Art History Paper †“the Denial of St. Peter” Essay

I chose the artwork â€Å"The Denial of St. Peter† attributed to Master Jacomo in the early mid-17th century made using either French or Italian style which consisted of oil on canvas. The physical condition of the painting looks good for how old it is and it looks clean. The painting represents a scene of a Roman guard interrogating St. Peter and a servant girl. St. Peter denies the fact that he is a follower of Jesus to the Roman soldier as the woman looks on. When I first saw the painting my eyes focused on the left side of the painting: then the followed the rest of it while noticing a dark and suspenseful scene that focused on the actions of many beings. The male and female on the right seem to on walk or stroll while the two males on the right are more on like a night shift or patrol. The people in the light are tenser and tight guarded while the two figures in the half dark are more open and smug with their facial features. The people in the light seem to be almost trying to hide something but it seems that the guard has some sort of idea what their hiding with the expression he has on his face. The guard might have a smug look but he has his right hand clenched meaning that not only is he cocky he is also a bit angry. The woman seems to be trying to hide the older male from the guard by putting his shroud over his face. The woman is also looking to her right which could give reference that she is lying because when people look to their right it says that they are using their right side of their brain which is where their creativity is. It seems that she is trying to lie in order to hide his identity. The old male however seems to trying to reassuring the guard to clear them of any suspicion that he may have of them. He is looking straight at him without doubt of fear in his eyes. The male that is in the back is trying to get a look at the old male and female while blocking most of the light from his ey es with his right hand. The most interesting part is the lit candle that the man is holding in his left hand as it is the only source of light in this painting. The guard is holding the other man by the wrist as he tries to steady the light. The funny thing is the light plays more of a role here than its purpose. The effect that is being used right now is the Chiaroscuro effect which is the strong contrast between light and dark. In this painting there is a strong contrast of light and dark. St. Peter and the woman faces and hands are in the light while their lower bodies are in darkness. For the guard if face and hand are the only parts in the light while the other male holding the candle only has half his face in the light. Also the light plays another part as showing who knows, who doesn’t, and who believes. In this painting the woman is in full light with the exception of some of her left side of the head this could refer that she knows of the old man’s identity. For the guard we can only see half his face in the light which could refer that he had some idea of who the old man is but he is still is not totally sure which could explain his smug expression of thinking he has St. Peter. The old man is in total light which is justified because he knows who he is so of course he would be know the truth. Now the man in the back his face would be in total light if his hand wasn’t covering his face which could mean he might know who the old man is but is trying to hide the truth from himself which is weird because he is the one holding the candle to begin with. Now the colors used in this painting are mostly dark colors. The scenery color does not vary. There is more focus on the middle detail and color on the middle portion of the painting rather than on the sides of the painting. The only color that really stands out is the red that the woman is wearing which draws attention to her. It could also mean anger showing that she could be angry that they were found. St. Peter is dressed in black with a brown shroud over his body and head. The black almost hides him in the dark with the brown as a cover if the light wasn’t on him. The black represent his inconspicuous while the brown shows his stability and connectivity with the earth. The guard is dressed in grey armor as he almost hiding himself in darkness also ready to come out whenever needed. It almost gives an ominous and depressing feeling when seeing that grey in the darkness. It could show that by meeting this guard they are facing exposure and loss. The light of the candle is again a bright color that illuminates everything in its path. It symbolizes the light of truth showing who knows what truth is and who does not. Other than those colors, darkness fills the rest of the painting obviously showing that this is a night scene. This painting showed a lot of effects that takes a while to see when looking at this painting. It was a great painting that I had a good sense of style and it had good hidden symbols in the painting. The artist really showed the Chiaroscuro effect and played the light well. Think the artist not only wanted to show â€Å"The Denial of St. Peter† but he also wanted to show how the light and truth have ties with each other. It probably the artist way of saying the light will always guide you to the truth.

Art Making Process Essay

The teaching of artmaking process is one in which there appear to be no right answers as it is frequently related to the teachers own understanding of the material at hand. (Schon, 1996). As art making is an open ended process there are a number of difficulties posed in instruction. One option is to engage art students in the process in a highly conscious and reflective manner. This was the mode in which the author conducted a 10 week course on the subject designed after intimately observing how contemporary artists worked. The first step in teaching art is said to be informing and inspiring students with various methods of artistic practice by playing video taped interviews of artists. The understanding of the use of big ideas by artists is one of the most important facets. Exploration of the big idea provides clarity of concept and insight into the artmaking process which is understood only through reflective practice. Maintaining documentation is also important. This provided students new perspectives in art making as they indulged in reviewing the big idea with personal relevance over a period of many weeks. Identification of the correct big idea is also linked to problems faced by artists in artmaking. Problems can be overcome with proper identification of the big idea and pursuing it with an open mind without an early closure. The delay in closure occurs when the artist discuses the concept repeatedly with himself thereby providing him better insight and enhancing creativity. Thus it is the understanding of the big idea, main concepts, the base and boundaries of knowledge which enable an artist to communicate his ideas most effectively to his audience. While artmaking cannot be taught in the form of a formula of success, the instructions provided in a generalized manner provide for developing the students creativity as well as art practice as was seen in the ten week artmaking project detailed in the article.

Research Report Essay Example | Topics and Well Written Essays - 3000 words - 2

Research Report - Essay Example The reasons for the rise of spirituality were diverse ranging from religion to superstition. People felt empowered and believed that they had a sense of direction when they get involved in spirituality. These findings open new doors for the governments in these countries which can create policies that can make people engage in more productive activities and make them rely less of spirituality for peace of mind and self-esteem. But the results also showed rise in happiness level and self-esteem. The success of spirituality can be harnessed to make people feel fulfilled. This study investigates into the phenomenal rise of spirituality in the western countries. Many things such as astrology and meditation have existed in the Oriental civilizations such as India, China and Japan. But these are being adopted by the western countries at a very fast pace. The purpose of this report is to investigate this issue by asking four major questions – There have been many studies on the rise of spirituality. Author of the book The God Delusion, Richard Dawkins, made a documentary called The Enemies of Reason. In that he argued that people believe in superstitions in order to escape hard realities of life. He wondered on the rise of spirituality at a time when science was giving answers to most of the problems. With these studies in the background, this study identifies the need to investigate the real reasons behind rise of spirituality in current age. This research is very important as it can provide an insight into the psychology of people and may also identify a social drift taking place in the western society. This research will address questions that aren’t usually asked in developed countries. Questions such as are people happy with the material prosperity, and are they seeking for some form of escape through spirituality, will be addressed by the present study. People, throughout the world, look for new experiences that would satisfy them.

Plan for visiting your policymaker Assignment Example | Topics and Well Written Essays - 1250 words

Plan for visiting your policymaker - Assignment Example For instance, the â€Å"clinical guidelines on the identification, assessment and management of overweight and obesity adults† was instituted in 1998. These guidelines were aimed to be employed by health practitioners dealing with obese and overweight individuals. The government has also instituted the weight-control information network to deal with obesity (Voigt & Kristin, 2014). The government has also instituted other policies and programs that seek to educate the people on their diets and the importance of exercising. Over the past few decades, the different presidents that have been in power have encouraged people to eat healthy and exercise. Prevention of child obesity is particularly significant in nursing practise as the primary goal is to prevent diseases and promote healthy lifestyles in the society (Institute of Medicine US, 2012). This goes a long way to imply that nurses must take a leadership role in responding to the epidemic of obesity. Voigt and Kristin (2014) argue that obesity can be caused by genetic, metabolic and environmental factors or a combination of the three. Nurses can promote healthy lifestyles patterns that minimizes the risk of overweight by emphasizing on the importance of breastfeeding, physical exercises, regular meals and nutritional weight counseling. Obesity is an issue that requires the input of almost everyone including federal, state and local policy makers. The policy makers involved in childhood obesity include my congressperson, Carlos Curbelo and Commissioner Juan C Zapata. I will try to contact the policy makers through calling their offices to book appointments. Terry (2013) acknowledges that calling is an appropriate way of booking for appointments or contacting policymaker’s offices. Each of these policy makers’ offices have contact numbers that are available on their webpages. Additionally, their numbers are listed on the blue pages of my phone book.

Landscape Archaeology Essay Example | Topics and Well Written Essays - 500 words

Landscape Archaeology - Essay Example in God, landscape painting, cartography and human enterprise, among others, to illustrate how humans have usurped nature, superimposed sophisticated concepts over it, and bent it to their own purposes. Using concepts fleshed out by such philosophers of science as Heidegger, Thomas moves on to explain human concepts of place and how ‘purpose’ is always superimposed thereon. ‘A place is always the place of something.’ (pp173) He also shows how landscapes seem to be contained within a frame: visual or conceptual, and of course monetary or pecuniary. Humans attach value to place, whether or not it is land, developed or otherwise. They also impose meanings of time, as evidence by the article itself; the value placed on findings from the past; as well as practical present-time use. In addition, Thomas shows a connection between land and the cosmos, seen as early as Neolithic times. Tombs, houses and henges not only formed part of the land form, but had some sort of attachment or reference to the skies and astral bodies; so that the passing of time and seasons were understood to affect the land and places where people lived and died, even from such an early time. We are deluding ourselves, Thomas suggests, if we try and interpret archaeological findings within the landscape using our modern mindsets. (pp 180) We would always fail if we superimposed our way of seeing things over whatever remnant of early undertakings we find. We cannot ultimately gain access to the meanings given to, and the uses of, the environment by early civilisations. He gives the examples of evidence of large gatherings in long houses, discoveries of human remains, patterns of movements between and around monuments, and other details studied through visions and understandings that are necessarily limited (or overly expanded) by modern knowledge. Thomas uses the literature, citing Gow, Frazer and Berger among many others, to extrapolate a theory of anthro-centrism: a superimposition (and

Currency Exchange Essay Example | Topics and Well Written Essays - 2250 words

Currency Exchange - Essay Example Around 1967 the GBP was devalued by 14 per cent, a major economic policy decision. Since then, the Sterling, on average has either depreciated or appreciated by 14 per cent every two years. The figure below shows how the exchange rate between the Sterling and the United States dollar has performed over a 5 year period. Around the mid 2008 shows a sharp drop in the exchange rate from around 2.0 to a low of 1.4. The significant change in the movement is attributed to the financial recession of the 2008. Sterling/US dollar exchange rate over the last one year For the past one year, the Sterling has been weak against the USD making the USD an expensive and valuable asset. This means that the clients needing to buys the currency are paying more and more. The reason for this slide may be due to the steps forward by Europe and the US. For instance the situation in Italy may be the key factor for the change in exchange rates which could go on for the next couple of weeks. Also, with a furthe r round of Quantitative Easing expected in the UK, the Sterling has been losing ground against the USD. Rates have dropped and whilst many expect this trend to continue should QE be confirmed, this in my view is being priced by the investors. Notably, the pound is not only losing ground against the USD but against other major currencies and the recent drop against the Euro and the Australian Dollar are no coincidence. It is floating around 1.50 against the USD and at an all-time low against the AUD. The following figures give the performance of the Sterling against the USD for a the last 12 months, narrowing down to 6 months and 3 months respectively. Key factors affecting the Sterling Being the sixth largest economy in the world and the third largest economy in Europe, the United Kingdom has a lot to boast about. For instance, the United Kingdom is able to produce over 60 per cent of its food with less than 2 per cent of the labour force. The United Kingdom also has numerous resour ces at its disposal, for instance oil, natural gas and coal. However the country was hit hard the financial crisis with growths rates going down to 0.3 per cent in Quarter 1 of 2010 and 0.4 per cent growth in Quarter 4 of 2009. The UK has a capitalist economy that is highly productive with a strong financial services industry. On a global basis the British Sterling Pound is undervalue. For instance, the purchase price parity shows that the Sterling should fall in value over time, but high investment flow potential means the opposite is what will happen, that is the Sterling will increase in value. According the United Kingdom’s Value Investor Survey, which reflects short term investment, the economic environment is very favourable for long term economic growth because of high scores on the government transparency, economic diversity and economic freedom. An undervalued currency, a favourable business environment and a moderate investment flow potential leads to a positive out look for the United Kingdom investments. Factors that have positively affected the British Sterling Pound are lower rates of unemployment and the foreign students. The UK, the US and Australia are the leading centres in attracting foreign students to study in their countries. These students obviously provide many social and monetary benefits that propel the economic activities of the host countries. Some factors that have negatively affected th

The Correctional System Case Study Example | Topics and Well Written Essays - 750 words

The Correctional System - Case Study Example The way prisoners were treated across the eras varies widely. "Criminal excesses of the 1920’s to 1930’s hardened the public’s attitude†¦J. Edgar Hoover†¦pushed for the now famous (or infamous) super maximum Alcatraz, which soon showed itself to be to expensive to run and maintain† (â€Å"Prison,† 2010, p. 1). Alcatraz was a maximum security prison on an island which is infamous for having housed many bitter and hardened criminals. The idea was that it was on an island so no one was able to leave. Alcatraz was one of the toughest prisons from which one could escape because, basically the security system was so complex. Not only that, but somehow, after having escaped from the prison itself, one would have to then get off the island. This required exceptional thought and planning. There were a few, and prisoners did escape from Alcatraz, although it was difficult. To contrast, in the 1800’s, â€Å"The convicted were not stripped of t heir belongings like in today's prisons, but they were searched for weapons or objects that could be used to escape†¦Many times the prisoners died of starvation and dehydration† (â€Å"Prison Life,† 2010, p. 1). In contrast, the prisoners of today are strip-searched and told that all their belongings must be put in a holding bin. These belongings are kept for the person until they are released from jail. Also, prisoners began to be treated better starting in the 20th century, and it increasingly got better from there on out. In the 1800’s. In the 1800's, as stated, prisoners were left to die in many cases, barely being given enough food on which they could sustain themselves. However, with the advent of psychiatric units and such, prisoners began to be regarded as people which were not lost causes to be put in a room and then allow someone to throw away the key. Rather, a more humanistic perspective was taken on in the mid-20th century in order to make the correctional system that we have today, where people are seen as being able to be rehabilitated instead of simply jailed. III. Secure Holding and/or Monitoring of Offenders The main difference in holding facilities between 1800 and 2000 is the fact that they simply got better. Living conditions improved over time for the inmate as time wore on. After awhile it was realized that prisoners couldn't just be allowed to languish in dirty, disorganized cells with dirt floors and a bench for a bed. People took note that prisoners were people too, and that they deserved a certain standard of living, however menial. IV. Alternatives to Incarceration Alternatives to incarceration involved being put in a chain gang in the early days (1800's till the 1950's). Although chain gangs can be seen today in the 21st century, usually those are for community service projects and are not as common. However,

Technology impact on Business - Essay Example The product was developed based upon the expectations of a citizen, such as customization and multiple communication options as well as virtual personalized assistance.(Lyon, 2008). Features of the IRS contact center include round-the-clock customer access using one click that can access the customer’s desired choice of assistance, such as chat, video or audio help. Using this improved technology, more customers can be served using fewer resources, thereby resulting in improved efficiency and higher levels of customer satisfaction. The author has pointed out that as the technology evolves, it is likely to improve further and become more mobile, requiring fewer devices to function efficiently. This article also provides details of improved technology devices that can contribute to a cleaner, greener environment. One of these is the EPEAT, a project of the Green Electronics Council. This program is a tool that helps customers to compare monitors, desktops and personal computers in order to evaluate their impact on the environment in terms of the waste they generate. For example, some of these electronic devices may contain toxic or hazardous compounds and if these components are not discarded properly, they could pose a danger to the environment and can also harm public health. The EPEAT technology consists of three basic components. The first is a standard that contains fifty one environmental performance criteria IEEE 1680 to 2006 Standard for the environmental assessment of personal computers. Twenty three of these fall under the mandatory criteria while twenty eight of these criteria are optional, but all of them fall under eight basic categories – the selection of materials, reduced use of environmentally sensitive materials, conservation of energy, ensuring product longevity and ensuring they are designed with end of life management so they can be

The difference between liberalism and socialism Essay

The difference between liberalism and socialism - Essay Example Nevertheless, wealth is shared in accordance with the individual’s contribution in the creation of that wealth (Wallerstein 73). This implies that those who involved a lot in the creation of the wealth get more share than those who does not contribute much in the creation of wealth. Socialist ideology also discourages the formation of classes or groups since it does not support competition among individuals (Wallerstein 74). To socialists, everybody in the society is considered equal, meaning that no one is considered superior to others. It is also noted that, in a socialist government, all resources are collectively owned by the people who also determine how the resources are to be utilized for the development of the society. Socialists also believe in equality and, therefore, discourage accumulation of capital in the hands of a few according to Wallerstein (73). China is a good example of a socialist state, which has also practiced the liberal system of government. Germany a nd the U.K. are another classical example of a country that have practiced both socialism and liberalism (Wallerstein 76). Liberalism is a political ideology which believes in the freedom of people in the society (Wallerstein 74). This implies that it is opposed to any restrictions on people in the society. According to liberalists, the state has the power to control all industries with the aim of eliminating malpractices. However, unlike in a socialist system that discourages private ownership of property, liberalists encourage private ownership of property (Wallerstein 75). The liberalist economic system, like a socialist system, is also structured in a manner the ensures fair distribution of national resources to every individual in the society as noted by Wallerstein (75). However, in a liberalist system, the activities of private welfare is regulated by the government or laws aimed at barring them from exploiting their

Discuss Shakespeares dramatic technique in Act one scenes 1 to 7 Essay Example for Free

Discuss Shakespeares dramatic technique in Act one scenes 1 to 7 Essay The chief character of the play is Macbeth. He is first of all Thane of Glamis and then inherits the title thane of Cawdor from an executed traitor. Instigated by a prophecy from the Witches that he will become king, and urged on by his wife, he murders King Duncan, and has himself proclaimed king. To secure his position, he is driven to commit further criminal acts, and plunges his country into civil war. After he is killed in battle by Macduff he is described as a dead butcher. The first scene is set on the moor that is bleak and desolate. This scene is one of desolation and devastation. The desolate countryside metaphorically separates the humans from the Witches who are used to open the play to introduce the idea of fate and destiny. From the stage directions, the battlefield creates a scene of death, carnage and destruction in line 4, when the battles lost and won and line 12 and 13, fair is foul and foul is fair a paradox is offered. How can fair be foul? How a battle be lost and won? The Witches chant in rhyming couplets and their speech is deliberately equivocal to create confusion in the mortals, as it is open t interpretation. He rhyming couplets give the effect of an incantation, while the thunder and lightning echo the noise of the battle. Similarly strange is thepaaradox that closes the scene: contained within it is the oxymoron, fair is foul, and foul is fair, a paradoxical idea that the Witches are able to transform what is good into evil, and make what is evil appear virtuous. These are also the first words spoken in the play by Macbeth, the echo establishes an unconscious contact with the Witches and is dramatically effective. We discover that the Witches are on the moor to meet with Macbeth. They seem to know where Macbeth will be. Once again they show that they can foretell the future. What can Macbeth the plays eponymous hero have to do with these abnormal, weird woman who look not like thinhabitants of earth? How does he fit into their plans? The opening scene heightens the audiences expectations, as Macbeth will soon appear on stage, the audience will try and establish exactly why the Witches hope t meet him. Witches held great significance for a Jacobean audience who believed in witchcraft. Witches were the objects of morbid and fevered fascination during this era. The Jacobeans were afraid and superstitious. They suspected that the Witches were credited with powers and could predict the future, fly, cause fogs and tempests, bring on night in daytime, kill animals and curse people, with fatal diseases as well as induce nightmares. By the use of this technique, Shakespeare knew that he would get his audiences attention with the opening scene. Although brief, this scene sets the supernatural atmosphere of the play, which is central to its dramatic action. In scene two, Shakespeare cleverly moves the scene to establish a different mood when introducing the humans. The seething battlefield replaces the moor, foul thunder is replaced by the sound of the military alarum and the humans replace the Witches. In this scene we meet Duncan, the King of Scotland, and his sons, Donalbain and Malcolm. Duncans supremacy is instantly established for he is the first to speak. They receive a report of the battle fought against the King of Norway and Macdonwald, the thane of Cawdor who has proved disloyal to Duncan. From the report he audience learns about the heroism and bravery of one of the King Duncans generals, Macbeth. Shakespeare continues to build suspense as he introduces the humans. The audience are also introduced to evil in man and the evil in warfare. The playwrights use of language helps to bring the battle to life and emphasises Macbeths importance. Dynamic verbs like, smokd, brandishd and unseamd suggest Macbeths skills and courage as his sword smokd with bloody execution. Once again we hear about Macbeth before we see him. Hw=e is spoken of in glowing terms and he becomes a hero in the eyes of the audience. Though he is referred to as a worthy gentlemen, there is still the memory that his name is connected with the Witches. Brave Macbeth kills Macdonwald by carving out his passage till he unseemd him from the nave to the chops with his brandishd steel that smokd with bloody execution. Part of this description highlights Macbeths bravery and valour, but the captains description of Macbeths unseeming of Macdonwald can be interpreted in different ways. Shakespeare intentionally paints an ambiguous picture of Macbeth. Macbeth, however, is still not satisfied until he had fixd [Macdonwalds] head upon the battlements. The decapitation of Macdonwald would support a more negative reading of Macbeth as oppose to his courageous behaviour. Scene two concludes with an ironic note as Macbeth is rewarded with the title of Thane of Cawdor which has been taken from that most disloyal traitor and given to Macbeth, who will prove to be more treacherous: No more than Thane of Cawdor shall deceive, Our bosom interest. Go pronounce his death, And with his former title greet Macbeth. The audience will realise that to make Macbeth Thane of Cawdor is a great mistake. We see Macbeth, the loyal subject and great hero who fought for good, change and become corrupt, and gradually deteriorate into a vicious tyrant. At the start of scene three, we meet the Witches once again in foul weather and we begin to witness their spiteful destructive nature. One sister has been killing swine while another has possession of a pilots thumb. The other Witch punishes a sailors wife by conjuring up a storm, therefore getting at her husband. From this the audience learns that the powers the Witches carry are limited. They cannot kill, but are able to create a climate for evil to flourish. Though his bark cannot be lost Yet it shall be tempest-tossd. The Witches curse on the sailor can be read as a prediction of Macbeths future. We are shown that the Witches are determined to make people suffer. They torment the sailor and drain him dry as hay. They deny him sleep at night and in the day. They ensure that he shall live a man forbid. However, Macbeth can be destroyed because the forces of veil are present within him. He alone causes chaos in the world by destroying the natural order when he deliberately choose the path of evil. The ship is a metaphor for the state of Scotland which is going to tempest tossd when Macbeth becomes king. A drum beats and Macbeth makes an entrance. We finally meet him and it is significant that his first appearance is with the Witches on the moor. This represents his connection with evil. His paradoxical word So foul and fair a day I have not seen arrests us because it replicates those of the Witches. This once again draws inferences between Macbeth and evil. This could suggest that the Witches have control over Macbeth, or that the hags are in some way similar to him. The appearance of the Witches like their speeches is equivocal. It is Banquo, who is used now as a dramatic device, who first comments on the bizarre appearance of the Witches. They look not like thinhabitants oth earth, and yet are ont and they appear to be women though they have beards. Banquo is calm and is looking for a reasonable explanation to why the Witches are on the moor, whilst Macbeth is impatient and wants an immediate answer to why the Witches have come with such prophetic greetings. The Witches prophesise that Macbeth, Thane of Glamis will become Thane of Cawdor and king hereafter, and that Banquo will have kings. Part of the prophecy is immediately fulfilled when a messenger announces that Duncan, King of Scotland has promoted Macbeth Thane of Cawdor. We the audience realise, that from the previous scene, Macbeth with his courage and bravery, and not the Witches powers, has won him the title Thane of Cawdor. Macbeth is rapt withal and becomes lost in his thoughts, as the Witches have articulated his secret desire of killing the King. His mind has been corrupted and he wants glory for himself. Shakespeare shows how evil can control what is good in Macbeth. Macbeth is torn between the forces of good and evil and he believes that he cannot be king unless evil wins over good. Macbeth reveals a disturbed mind, when he speaks his own thoughts aloud in a soliloquy, as murder is in his mind. His first thought is to leave everything to chance: If chance will have me king, why chance may crown me, Without my stir Macbeth has asked Ross and Angus, the messengers, why they dress [him] in borrowd robes- why they call him by the name of Cawdor, when Cawdor lives. By the end of the scene Macbeth is contemplating borrowing the kings robes. The reference to clothing in this scene is symbolic. The imagery of clothing indicates status, prestige and symbolises a persons title. By using the imagery of clothing, Shakespeare is trying to show that if you wear someone elses clothes they may feel uncomfortable and they may cleave not to their mould because they are borrowd. Therefore if Macbeth wears the robes of the kingship they will cleave not to [his] mould as he is not worthy of the kings throne. When the Witches depart in this scene, Macbeth orders them to, Stay, you imperfect speakers tell me more. Macbeths curiosity has got the better of him and his demand of the Witches indicates his obsessive interest with these weird women and their prophecies. The Witches vanish into the air as they do not receive orders from mortals and will not be dictated to. The source and purpose of their evil remains a mystery to the audience. Shakespeare metaphorically compares the disappearance of the Witches to bubbles. Macbeths life can also be represented as a bubble, as the honour, love, obedience and troops of old friends that he has will soon disappear under the wishes they had stayd. Ross and Angus enter, they are used as dramatic devices to convey to Macbeth the Kings decision to reward Macbeth with the title Thane of Cawdor. Macbeth and Banquo are both shocked as the devil has spoken the truth. Macbeth is already snared by the Witches prophecies, as he believes that, The greatest is behind On the other hand, Banquo can see through the trickery of the Witches. He is sceptical and can see through Macbeths motives in asking him whether he hopes his heirs will become kings. Banquo tries to warm Macbeth against the instruments of darkness. He tries to convince Macbeth that the Witches tell simple truths that are easy to believe, so that when they want to deceive people with more important matters they will also be believed. And often times, to win us to our harm, The instruments of darkness tell us truths, Win us with honest trifles, to betrays In deepest consequence. Banquo is portrayed b by Shakespeare in a positive light, as he does not make him an accomplice in Duncans murder. The stage directions show that Macbeth turns aside. This informs the audience that he is talking to himself. This symbolises Macbeth turning away from the other characters in the play as well as the path to righteousness. Shakespeare uses dramatic language to emphasise Macbeths horror. His seated heart knock at his ribs and his hair is unfixed. The scene concludes with Macbeth and Banquo following Ross and Angus to meet the king. The audience are filled with a sense of apprehension and anticipation. One question remains: how will Macbeth get the crown? Scene four opens with a focus on treachery and betrayal. King Duncan hears his son, Malcolm, relate how the treacherous Cawdor has been executed. Also in this scene Duncan reveals his lack of knowledge regarding his own thanes. He exposes a very human weakness-one which lies at the heart of the play- the difficulty of working out who is loyal and who is pretyending loyalty: Theres no art to find the Minds construction in the face. It seems likely that there is an implicit criticism of Duncan here: a good King should be able to assess the loyalty of all his servants. Duncans failure to do so reveals his limitation as a monarch- one who is taken in by appearances. Dramatic irony is introduced where Duncan announces that Cawdor was a Kinsman in whom he had absolute trust. Macbeths betrayal will replicate that of Cawdors. When Macbeth and Banquo enter, Duncan immediately singles out Macbth for praise, oworthiest cousin. The superlative worthiest subtly reveals that Macbeth is yet another thane in whom Duncan has absolute trust. Macbeth is the most dangerous of the potential traitors because he is closest to the king. Scene four is the only time we see Macbeth and Duncan together and Shakespeare contrasts the forces of good and evil. Macbeths deceit and hypocrisy is shown in this scene when he praises King Duncan and promises to honour him with loyalty. He convinces Duncan that servicing your highness will be its own reward. Macbeth is a hypocrite because in the previous scene he has contemplated the murder of Duncan. Duncan ironically comments that he has started to metaphorically plant Macbeth, meaning that he will make sure that Macbeth grows greater and stronger as a reward for his services. This is ironic because what is growing in Macbeth is the seed of ambition to be King himself. Shakespeare deliberately plants an obstacle in Macbeths path when Duncan announces that his eldest son, Malcolm, is to succeed him as king. Macbeth now sees Malcolm as an obstacle between himself and the throne which he must fall down or else oer leap. Shakespeare uses the euphemism that Malcolm is a step he must oer leap, in order to disguise the realisation that Malcolm must be eradicated. In an aside, symbolically turning his back on the King, Macbeth reveals to the audience, and articulates for the first time his black and deep desires. He invokes the powers of darkness to hide [their] fires. At the beginning of scene five, we see that Macbeth and his dearest partner of greatness, Lady Macbeth, have a very close relationship. This is a contrast to how distant they become later on in the play when Macbeths fiend-like queen is innocent of the knowledge. She is innocent of the knowledge as Macbeth does not confide about his plans to kill Banquo, and she shows ignorance of Macbeths murder of Macduffs family. She asks in her rambling state where the Thane of Fifes wife is now. Macbeths lack of sorrow when he hears of his wifes death is also indicative of how they have drifted apart. In all the public scenes in the play she acts like the innocent flower; in the private scenes we see the serpent undert. It is suggested that she commits suicide as she has become lonely and rather isolated. Lady Macbeth does not live up to the expectation of a typical Jacobean/Elizabethan woman. She wants the spirits the spirits to unsex her so that she can be tough and strong. Lady Macbeth uses strong imperatives and determined language that is brutal and violent. This is because she is delighted with her husbands letter and shows determination that he will become king. The letter form Macbeth describes the Witches appearances, their prophecies-in particular that which promises the throne to Macbeth- but does not mention King Duncans announcement of his heir; the audience can therefore, assume that this letter was written immediately after the events which occur in the third scene. Although Lady Macbeth knows that her husband is ambitious, she is aware that he is too full othe milk of human kindness. She says that ruthlessness is an illness that Macbeth does not have. This is not a true portrayal of Macbeth, because from the previous scenes and throughout the play we see that Macbeth is not too full othe milk of human kindness but lacks it. Perhaps she is comparing Macbeth to herself and is saying that Macbeth is not as ambitious as she is. Lady Macbeth under estimates the powers of her conscience. She see her conscience as her weakness, not realising until after Duncans murder how she will pour[her] spirits in his ear. She has also decided that nothing will stand between him (or her?) and the golden crown ( a metonym for the throne). Lady Macbeth greets her husband like the Witches, which subconsciously links her to evil and believes that her call to the murdering ministers has been answered. She feels now the future in the instant and that she is beyond this ignorant present. This is ironic as Lady Macbeth is still being ignorant. Lady Macbeths confidence is a contrast to Macbeths uncertainty. She advises him to look like the innocent flower but be the serpent undert and to only look up clear. She is in control of their relationship and tries to help Macbeth find the necessary determination to do the deed. Though Lady Macbeth appears to be confident, she uses euphemisms when talking to Macbeth about the nights great business. At this point in the play, Macbeth has been tempted to commit regicide, however he has tried to resist temptation. Macbeths resistance, however, is not vigorous enough to stand up to his wifes ability to manipulate him. The scene closes dramatically with Lady Macbeth emphatic affirmation that Duncans fate rests in her hands- leave all the rest to me. Scene six sees King Duncan arriving at Macbeths castle, he and Banquo talk about how pleasant a place it is to visit. They comment that the air recommends itself and is delicate. This is ironic in view of Lady Macbeths words in the previous scene, and even more so when compared with that of the Witches say about the fog and filthy air surrounding their evil deeds. Duncan also says that he is grateful for the love which is shown to him. Here again, Shakespeare uses dramatic irony. The idea that Duncan feels safe and loved in the surroundings is ironic as this will be the scene of his murder. This creates a sense of anticipation for the audience. It shows Duncans naivety, as he keeps full trust in Macbeth and his fair and noble hostess. We are presented in this scene with images of tranquillity and the words host and guest are repeated. At the beginning of scene seven, we once again see the struggle between the forces of good and evil. Macbeth cannot make up his mind whether to kill Duncan and he wrestles with his conscience in his soliloquy. He knows that the murder would be wrong and would he would end up paying the price for his crime, but he has vaulting ambition that is very persuasive to his conscience. Though Macbeth is driven by his vaulting ambition he redeems himself and will proceed no further in this business, as Duncans murder will be like angels, trumpet-tongud and heaven would be outraged. The verb will shows Macbeths determination to keep his soul. Toward the end of his soliloquy Macbeth compares his excessive ambition to a horse that tries to jump too high and fall on the other side of the fence. Within the soliloquy Macbeths thoughts seem to be fragmented, this is shown by the use of many full stops. Lady Macbeth verbally assaults her husband using violent language that becomes heightened. She accuses him of being a coward and questions his manhood: when you durst do it, she says, then you were a man. She is forceful in her language and she conjures up images of horror. She knows, How tendertis love the babe that milks me: I would, While it was smiling in my face, Have pluckd my nipple from boneless gums, and dashd the brains out Lady Macbeth seems to have been granted her earlier wish to the evil spirits to Fill me from the crown to the toe top-full Of direst cruelty. Macbeths earlier decision not to kill Duncan crumbles under the scornful attack of his wife, especially when his bravery is questioned. However, he is still worried bout what will happen to then if they should fail. Shakespeare cleverly ends the scene with rhyming couplets. Away, and mock the time with fairest show, False face must hide what the false heart doth know. The rhyming couplets symbolise their connection with the Witches and evil as they complete their preparations for murder. The audience waits in anticipation. Throughout Act one Shakespeare creates an atmosphere of tension by exploring the theme of evil against good. Symbolism is used to emphasise this theme. Dramatic irony, dramatic language and strong descriptive scenes also help to build up an atmosphere of tension.

Rectification circuit for a dc power supply

Rectification circuit for a dc power supply 1. Introduction Most of the electronic devices do not power on AC basis, and if so it will conduct a lot of power and will be damaged the first moment it operates. Thus a device that reduces the voltage and correspondingly smoothes the output voltage to become much more stable and reliable to use than the AC which is the DC is needed. A question may arise that asks why do not use batteries to supply a DC voltage. Well, it is a good it a good question, but batteries are expensive and does not handle large electronic devices. Imagine having a desktop on batteries and having to change its battery every half an hour or so, it is a nightmare. As a result, in this case, a linier DC power supply that operates from fixed (ex: at home) AC voltage is needed. A rectification circuit do all that automatically. It smoothes and filters the current and make it a better than a battery DC source. The report paper will focus primarily on the technical aspects of the Rectification circuit used in the linear DC power supply. Other aspects than mentioned will not be included. 2. Discussion 2.1. Linear power supply AnACpowered linear power supply usually uses atransformerto convert the voltage from the wall outlet (mains) to a different, usually a lower voltage. If it is used to produceDC, arectifieris used. A capacitoris used to smooth the pulsating current from the rectifier. Some small periodic deviations from smooth direct current will remain, which is known asripple (Wiki, 2009). The voltage produced by an unregulated power supply will vary depending on the load and on variations in the AC supply voltage. For critical electronics applications alinear regulatorwill be used to stabilize and adjust the voltage. This regulator will also greatly reduce the ripple and noise in the output direct current. Linear regulators often provide current limiting, protecting the power supply and attached circuit from over current (Wiki, 2009). Figure 1 illustrates two common linear power supply circuits in current use. Both circuits employ full-wave rectification to reduce ripple voltage to capacitor C1. The bridge rectifier circuit has a simple transformer but current must flow through two diodes. The centre-tapped configuration is preferred for low output voltages since there is just on diode voltage drop. For 5V and 12V outputs, Schottky barrier diodes are commonly used since they have lower voltage drops than equivalently rated ultra-fast types, which further increase power conversion efficiency. However, each diode must withstand twice the reverse voltage that a diode sees in a full-wave bridge for the same input voltage. The linear voltage regulator behaves as a variable resistance between the input and the output as it provides the precise output voltage. One of the limitations to the efficiency of this circuit is due to the fact that the linear device must drop the difference in voltage between the input and output. Consequently the power dissipated by the linear device isVi-VoÃÆ'- Io. While these supplies have many desirable characteristics, such as simplicity, low output ripple, excellent line and load regulation, fast response time to load or line changes and low EMI, they suffer from low efficiency and occupy large volumes. Switching power supplies are becoming popular because they offer better solutions to these problems (National, 2002). 2.2. Transformer Atransformeris a device, figure 2, that transferselectrical energyfrom onecircuitto another throughinductively coupledconductorsà ¢Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬the transformers coils. A varyingcurrentin the first orprimarywinding creates a varyingmagnetic fluxin the transformers core, and thus a varyingmagnetic fieldthrough the secondarywinding. This varying magnetic fieldinducesa varyingelectromotive force (EMF)or voltage in the secondary winding. This effect is called mutual induction. If aloadis connected to the secondary, an electric current will flow in the secondary winding and electrical energy will be transferred from the primary circuit through the transformer to the load. In an ideal transformer, the induced voltage in the secondary winding (VS) is in proportion to the primary voltage (VP), and is given by the ratio of the number of turns in the secondary (NS) to the number of turns in the primary (NP) as follows: Step down transformers convert electrical voltage from one level or phase configuration usually down to a lower level. They can include features for electrical isolation, power distribution, and control and instrumentation applications. Step down transformers typically rely on the principle of magnetic induction between coils to convert voltage and/or current levels. Step down transformers are made from two or more coils of insulated wire wound around a core made of iron. When voltage is applied to one coil (frequently called the primary or input) it magnetizes the iron core, which induces a voltage in the other coil, (frequently called the secondary or output). The turns ratio of the two sets of windings determines the amount of voltage transformation. An example of this would be: 100 turns on the primary and 50 turns on the secondary, a ratio of 2 to 1. Step down transformers can be considered nothing more than a voltage ratio device. With step down transformers the voltage ratio between primary and secondary will mirror the turns ratio (except for single phase smaller than 1 KVA which have compensated secondarys). A practical application of this 2 to 1 turns ratio would be a 480 to 240 voltage step down. Note that if the input were 440 volts then the output would be 220 volts. The ratio between input and output voltage will stay constant. Transformers should not be operated at voltages higher than the nameplate rating, but may be operated at lower voltages than rated. Because of this it is possible to do some non-standard applications using standard transformers. Single phase step down transformers 1 kva and larger may also be reverse connected to step-down or step-up voltages. (Note: single phase step up or step down transformers sized less than 1 KVA should not be reverse connected because the secondary windings have additional turns to overcome a voltage drop when the load is applied. If reverse connected, the output voltage will be less than desired). 2.3. Rectifier Arectifieris an electrical device that convertsalternating current(AC) todirect current(DC), a process known asrectification. Rectifiers have many uses including as components of power suppliesand asdetectorsofradiosignals. Rectifiers may be made ofsolid statediodes,vacuum tubediodes,mercury arc valves, and other components (Wiki, Rectifier, 2009). While half-wave and full-wave rectification suffice to deliver a form of DC output, neither produces constant-voltage DC. In order to produce steady DC from a rectified AC supply, a smoothing circuit orfilter,is required. In its simplest form this can be just areservoir capacitoror smoothing capacitor, placed at the DC output of the rectifier. There will still remain an amount of ACripplevoltage where the voltage is not completely smoothed. Sizing of the capacitor represents a trade-off. For a given load, a larger capacitor will reduce ripple but will cost more and will create higher peak currents in the transformer secondary and in the supply feeding it. In extreme cases where many rectifiers are loaded onto a power distribution circuit, it may prove difficult for the power distribution authority to maintain a correctly shaped sinusoidal voltage curve (Wiki, Rectifier, 2009). For a given tolerable ripple the required capacitor size is proportional to the load current and inversely proportional to the supply frequency and the number of output peaks of the rectifier per input cycle (National, 2002). The load current and the supply frequency are generally outside the control of the designer of the rectifier system but the number of peaks per input cycle can be affected by the choice of rectifier design. A half-wave rectifier will only give one peak per cycle and for this and other reasons is only used in very small power supplies. A full wave rectifier achieves two peaks per cycle and this is the best that can be done with single-phase input. For three-phase inputs a three-phase bridge will give six peaks per cycle and even higher numbers of peaks can be achieved by using transformer networks placed before the rectifier to convert to a higher phase order (Wiki, Rectifier, 2009). To further reduce this ripple, acapacitor-input filtercan be used. This complements the reservoir capacitor withinductor and a secondfilter capacitor, so that a steadier DC output can be obtained across the terminals of the filter capacitor. A more usual alternative to a filter, and essential if the DC load is very demanding of a smooth supply voltage, is to follow the reservoir capacitor with avoltage regulator. The reservoir capacitor needs to be large enough to prevent the troughs of the ripple getting below the voltage the DC is being regulated to. The regulator serves both to remove the last of the ripple and to deal with variations in supply and load characteristics. It would be possible to use a smaller reservoir capacitor (these can be large on high-current power supplies) and then apply some filtering as well as the regulator, but this is not a common strategy. The extreme of this approach is to dispense with the reservoir capacitor altogether and put the rectified waveform straight into a choke-input filter. The advantage of this circuit is that the current waveform is smoother and consequently the rectifier no longer has to deal with the current as a large current pulse, but instead the current delivery is spr ead over the entire cycle. The downside is that the voltage output is much lower approximately the average of an AC half-cycle rather than the peak. 2.4. Regulator The regulator is an electrical regulator designed to automatically maintain 3. The Proposed Circuit * The proposed circuit shall have an input voltage equals to 220v. * A centre-tapped step down transformer with 220v output and 12v output. * 2 diodes (1N4001) working independently (note: duel regulated) as half-wave rectifiers. * 2 capacitors (1000u) to smooth the signal. * 2 voltage regulators (LM7815C) to regulate the coming voltages from the capacitors. * 2 small values capacitor (10u) for final smoothing for the output voltage. * The output voltage of 0-5v. 4. Conclusion One of the best ways to output an efficient and reliable DC power supply is to use linear power supply, which uses a step-down transformer, a rectification circuit, a regulator and a filter. The step-down transformer takes the voltage down from 220v to 12v, then the rectification circuit smoothes and filters it using capacitors and diodes, as a result, the output DC voltage would be 0-5v with a minimal ripple factor using the proposed circuit as mentioned.

Emotional, Behavioral, and Psychological Disturbances in Neglected Chil

Every year millions of children are abused and neglected worldwide. Child abuse is a global concern. It has severe outcomes on the children who are victims, and often the effects are long-lasting. Child abuse is a highly under-reported crime although of those reported, neglect accounts for the majority of child abuse cases (Pala, ÃÅ"nalacak, & ÃÅ"nlà ¼oÄŸlu, 2011). Neglect in children often has more dire consequences than other types of child abuse (DePanfilis, Children’s Bureau, & Office on Child Abuse & Neglect, 2006). One consequence especially prevalent in neglected children is insecure or lack of attachment to a primary caregiver. John Bowlby’s research has shown the evolutionary importance of infant attachments, further research shows that infant attachment styles carry over into adulthood (Levine & Heller, 2011). Neglected children showed disturbed attachments that manifest into developmental delays and behavioral problems. Through treatment neglected childr en aim to learn how to create secure attachments (Hardy, 2007). Defining neglect Numerous teachers, family doctors, social workers, among other professionals will be faced with child abuse and have the responsibility of reporting mistreatment. Therefore, it is important for these specialists to be able to recognize signs of child abuse and neglect (Pala, et al, 2011). The World Health Organization Consultation on Child Abuse Prevention currently recognizes four types of child abuse: physical, sexual, emotional, and neglect. Dr. Bengà ¼ Pala and his colleagues found that neglect accounted for up to 71% of the child abuse cases in 2008 around the world. They defined neglect as a parent or caregiver’s precedence of failure to provide for the development and welfare of the child ... ...on regulation and emotional stability (Hardy, 2007). From 2000 to 2004, 7.6 out of every 1,000 children were reported as being neglected. The Third National Incidence Study of Child Abuse and Neglect found that less than a third of child maltreatment is reported. The signs of neglect can often be subtle and hard for other adults to recognize; this attributes to the underreporting of neglect cases (DePanfilis, et al., 2006). Due to the fact that child abuse distresses millions of children every year and millions more suffer silently, it is important to improve research on the dilemma. Several studies acknowledge that there is an absence of research on attachment theory in neglected children (Venet et al.) It is imperative that research on attachment disorders drastically advance so that effective treatments can be developed allowing neglected children to heal.

Essay --

â€Å"Heroes take journeys, confront dragons, and discover the treasure of their true selves.†- Carol Lynn Pearson. Heroes have many different qualities depending upon the person you believe is a hero in your eyes. A Hero’s qualities could be being Brave, Trustworthy, Loving, a Leader, Intelligent, and Kind. Now those are just some common characteristics to â€Å"make† or to â€Å"be† a hero. Some heroes to others could be in their family, their friends, or even famous people that have passed or are still alive. A characteristic that stands out to many is Bravery. Being a brave person can be challenging. Martin Luther King Jr., for example, is a brave person and a hero. † A man who won't die for something is not fit to live†-Martin Luther King, Jr. He stood up for what he believed in and stood up for all of the ones who were frightened to say something. His speech,† I Have a Dream† caught the attention by everyone in the whole entire world. Martin was arrested upwards to about twenty times and was assaulted about four times (nobelprize.org/MartinLutherKingJr.). How could Martin Luther not be a hero? He risked his life for Blacks and for their rights. Would you do this if you were in his shoes? Another example of a Brave hero would be Anne Frank. † And finally I twist my heart round again, so that the bad is on the outside and the good is on the inside, and keep on trying to find a way of becoming what I would so like to be, and could be, if there weren't any other people living in the world†-Anne Frank. Even though she was younger and may not have understood everything, she was still a brave and strong person. She had to go into hiding to save her life and her families. They all had to stay quiet and get along with all the families they were ... ...n a season, and the most valuable player of the year. All of his awards and accomplishment showed that it doesn’t matter what you like. Appearance doesn’t determine if you are skilled or not, if you are brave, or even a hero. In conclusion, the qualities are what make up a hero. Not the ways they look, act, or speak, but they all have one thing in common which is standing for what they believe in. In any situation that occurs. Someone’s appearance does not prove or show you what they can do or how they can act. A hero’s actions or skills are what make them a hero. You don’t have to be a superhero with a cape or a muscular man to make everyone think you are a hero. You could be the quietest person in the school or your town for that matter. If you are willing to stand for what you believe in and do what you think is the right decision, you could be a hero to many.

Moving Towards Totalitarianism in Our Pursuit of Social Justice Essay

Moving Towards Totalitarianism in Our Pursuit of Social Justice Pursuit of various visions of social justice probably accounts for most human misery. What's more, the historical pattern that has emerged has been one whereby one form of injustice is replaced by one that is far worse. Russia's 1917 revolution expelling the Czars, and their injustices, ushered in Lenin, Stalin and a succession of brutal dictators who murdered tens of millions in the name of the proletariat revolution. The injustices of Chiang Kai-shek were replaced with those of Mao Tse-tung; Castro's ousting of Batista or Ayatollah Khomeini's toppling of the Shah of Iran produced regimes far more brutal. In Africa, after independence, the injustices of colonial powers were replaced with those of brutal dictators. The slaughter of nearly 200 million poor souls, not including war deaths, during the 20th century, was a direct result of pursuit of visions of social justice such as income equality, promoting the common good and fighting the so-called evils of capitalism. As if by design , measures taken to produce what was seen as the good society lowered both the common man's human rights protections and his standard of living. By contrast, after the American revolution, we laid the groundwork that produced the world's freest people. However, for most of the 20th century, we have been losing ground. If you ask the question which way are we heading - away from totalitarianism or towards it - there is no question that, by tiny steps at a time, we are heading towards totalitarianism and arbitrary governmental abuse and control. Some Americans are naive enough to think that the oppression seen in other countries can't happen here. But let's not forget that the countr... ...t determine what is or is not moral conduct. In Nazi-Germany, there were laws that required the reporting of a person hiding a Jew. In our country, the Fugitive Slave Act made assisting runaway slaves a crime. In apartheid South Africa, hiring blacks for certain work was illegal. In the former East Germany, assisting people in their efforts to escape to the West was illegal. Would any decent person demand that any of these laws be obeyed? Decent people must always ask: Does the law have a moral basis? Liberty is not mankind's normal state of affairs. Liberty is fragile. Our liberties are under siege because most Americans are ignorant about our Constitution and its philosophical underpinnigs. Thus, we fall easy prey to political charlatans and quacks all too ready to exploit this ignorance in their quest for power and to satisfy popular visions of social justice.

Michigan

Despite the governor’s pretty language abot alternative fuels and efforts to create a partnership with Sweden for the development of alternative fuel use in Michigan, the state is still nowhere near where it should be in terms of use of alternative fuels. The reasons are simple and complex all at the same time. People don’t want to buy vehicles which use alternative fuels if they can’t buy that fuel at the local store and local stores don’t want to carry a product that no one is buying.  Ã‚   On a website for Ford Truck enthusiasts,   one consumer said he would love to have a biodiesel truck or a flex fuel Ford Ranger, but even with the incentives the state has adopted to promote the use of these fuels, they are not generally available at the corner store. In addition, Michigan’s incentives, such as a 12 cents per gallon sales tax credit on some alternative fuels, do not account for market fluctuations that are inherent in a system that relies on only ethanol and oil fuels. In the worst conditions, extreme versions of the summer of 2007, a drought in major corn-producing states could raise the price of ethanol and OPEC production games can increase the price of gasoline. Because biodiesel and other alternative fuels are not easily used in most vehicles, consumers are still caught in a Catch-22. Switching to one alternative fuel does not make it readily available. With diversification as the car manufacturers look for more efficient ways to propel their vehicles and save the environment,   consumers cannot be assured that their â€Å"alternative fuel† vehicle of today is not going to be an obsolete paperweight with no fuel available in just a few years. The sad thing is that for all the attacks on the automotive industry, Michigan and automakers are trying to come up with a solution for the environment and for business. Unfortunately, the businesses and researchers can’t agree on what the best alternative fuel source is.   Ethanol relies of the growing season, propane is still a fossil fuel and methane is difficult to transport safely. Biodiesel, a form of heavy vegetable oil, also requires good crops. With shifting weather patterns across the globe, manufacturers are loathe to rely on a system which necessitates a good growing season. Furthermore, many activists are now arguing that the farmland used to create corn and soy beans for use in alternative fuels further contributes to the global warming problem by destroying farmland. In short, Michigan is trying to address the alternative fuel needs of the state and the country, but until the technology and production capability meet, consumers are less likely to buy into the alternative fuel option than officials would like. Hybrids are popular, but largely unproven in terms of long-term mechanical durability and alternative fuel cars just aren’t attractive for mass consumption. Until Michigan can do something about the supply chain for alternative fuels and the reliability of cars built to use them, the alternative fuels effort in Michigan will be strong, but not terribly effective.

Is the Earth large or small? Essay

Any information concerning the size of the earth is likely to refers to this aspect its description within the context of relativity. As one of the planets in the solar system, the earth is large relative to its planetary counterparts. It is the largest and most massive of the terrestrial planets (which include Mars, Venus, and Mercury) within the solar system. In addition, the earth is also denser than the other planets within its solar system. However, compared with the non-terrestrial planets (Saturn, Jupiter, Uranus and Neptune) the earth is very small. In comparison with the sun, the earth is tiny. The mass of the earth is 5. 9736 X 1024 kg. This, compared with the mass of the sun is 1. 99 X 1030 kg, which is 332,946 times that of the earth. On the size scales within the solar system, therefore, the earth might be considered medium sized. However, since the sun is quite miniscule compared to other stars and to the physical bodies within and beyond the galaxy, the sizes of the earth on a universal scale approaches the infinitesimal. 2. What are the major differences between parallels and meridians? Parallels or latitudes differ from meridians primarily in the directions in which they run. While parallels always run east-west, meridians run north-south in a way that allows each to cut (cross) each parallel at a different angle. This is because meridians all run through the axes of the earth, and this ensures that they all converge upon the poles. The parallels or latitudes run parallel to each other, and this ensures that they never meet each other in their journeys around the earth. One effect that this difference (in parallelism) has on the two types of lines is that while parallels are always equidistant from the equator and poles at every point on its circumference, meridians change their distances from each other the closer or further away they are from the poles. Therefore, at the equator, the distance between any two given meridian will always be greater than at any other latitude on the earth. 3. Why are vertical rays of the Sun never experienced poleward on the tropic lines? The sun’s vertical rays are experienced only between 23. 5oN and 23. 5oS primarily as a result of the tilt of the earth’s axis. This tilt measures 23. 5 degrees, so as the earth revolves around the sun, its poles tilt toward or away from the sun at this angle. During the summers (which alternate between opposing parts of the year in for the northern and southern hemispheres), the poles are tilted toward the sun. However, the angle this causes the earth to make with the sun ensures that the angles of the sun-rays hitting the earth are less than the 90 degrees which would constitute a direct hit. Because of this tilt, the rays of the sun are sometimes able to shine directly on such parts of the earth that always between the latitudes that remain in the direct path of the rays after the 23. 5o tilt. The further north or south of these latitudes one goes, the less of a direct contact the earth makes with the sun’s rays. In fact, the extreme of this is that very close to the poles at certain times of the year, the sun’s light is not seen at all. 4. On which day of the year do the vertical rays of the Sun strike the farthest north of the Equator? What is the latitude? Why? The days on which the sun’s vertical rays hit the earth at the angle farthest from the equator is approximately December 22. This is known as the Winter Solstice, and describes the time when the Northern Hemisphere experiences its shortest daytime period (or longest night-time period). The latitude at which this occurs is the 23. 5oN, which represents the latitude of the Tropic of Cancer. This occurs primarily because of the earth’s axial tilt, which is about 23 degrees toward or away from the sun. At the time of the Northern Hemisphere’s Winter Solstice, the earth is tilted away from the sun, yet the sun’s direction from the earth at that time compensates for that tilt so that its rays hit at the spot farthest north that is possible at any given time. This â€Å"spot† occurs at 23o north of the equator. 5. Explain the implications of the statement, ‘No map is totally accurate. ’ According to mapping standards held by the Unites States (and likely by other countries), maps have to maintain accuracy within a given scale. For example, for scales where one (1) inch on the map represents 24,000 inches on land (or sea), the inaccuracy level of the map should not exceed 1/50th of an inch in more than 10% of the points (USGS). These standards are based upon the premise or understanding that no map can be completely accurate. However, what this means is that at minute scales on the ground or sea, it becomes impossible to locate things with a large degree of accuracy. This can be seen more clearly when it is known that 1/50th of an inch on a 1:24,000 scale represents 40 feet (USGS). Therefore, in important expeditions that require map use, a user may expect to be ignorant concerning the exact location of a designated point within at least a 40-foot radius. 6. A globe can portray Earths surface more accurately than a map, but globes are rarely used. Why? Globes are more accurate than maps because, while the map distorts the latitude lines, the shapes of its landmasses and other features, these are kept in true to form on globes. However, globes are rarely used because of their three-dimensional natures that make them more difficult to navigate than two-dimensional maps. The shapes made by the intersection of parallels and meridians are also less like simple geometrical shapes. Because of the way in which the latitude lines are portrayed on maps (as vertical and parallel, thereby creating the illusion of squares) these are usually more suited to calculations done by the lay person or navigator. These parallel latitudes represent not real latitude lines but what has been termed loxodromes (also known as rhumb lines). These rhumb lines actually represent the constant bearing of a compass and calculations using these lines make it easier for navigators to determine the direction of their courses (Rosenberg). Maps are also more intuitively like humans view the surface of the earth. From our perspective, it does not appear to be a sphere, but a large expansive area. Therefore, maps accord more to our everyday experience and are easier for humans to translate. 7. Distinguish between GPS and GIS. Provide ways in which these tools can be useful to physical geographers. The Global Positioning System or GPS is a system that facilitates the location of objects or areas on or around the earth based on a group of satellites which have been launched into the earth’s orbit at about 11,000 miles (Corvallis). This differs from a GIS, which is a Geographical Information System—a database that holds the location of a large number of locations on the earth. The difference between the two lies in that while the GPS is the system for mapping an object, the GIS is the actual object that whose position is being mapped. The GPS system is of immense importance because of the level of accuracy it provides whether on the scales required by navigators or those required for geodesic positioning (ISSA). GIS allows geographers to be able to know, map, and locate specific regions or objects on the earths surface. It also allows them to chart paths from one location to the next by accurately calculating vectors that denote the relative distances and directions between given locations. The GPS continually expands the data available by embodying the technology that allows new places to be located and pin-pointed.

Digital Media

Introduction: You may have heard of digital media, but you may have no idea what it is and how it can help you out when it comes to marketing. It's definitely important that you get up to speed so you can use this to benefit your business. Basically digital media refers to any type of electronic media out there. Today media can be accessed in many ways, including with hand held devices like mobile phones, laptops, desktops, mp3 players, and more. Digital media must be stored in an electronic way, so there is a lot of digital content on the internet today, including text content, pictures, audio content, as well as video content.Through the history of internet, digital media has been developing in various ways. Here's we'll take a look at how it has affected the Internet and ways that it may be integrated moving forwards (Rogers 2006). One type of digital media is text; this in fact represented the very first explosion of  this  type of content  out there on the Internet. When t he Internet first got big, there was an explosion of content on the web, especially with all the text editors and word processing options out there today (Rogers 2006).Larger companies started to put date on computers instead of storing it in cabinets, and the internet definitely allowed a great way to share, transfer, and store content as well. As the Internet grew, images began to appear. Instead of just text emails, soon people could send photos, and soon photo sites for sharing photos began to pop up. Then in the middle 1990s, audio began to become an important part of digital media with the mp3 files that could be easily used. Soon music and more was shared online with sites that allowed you to share audio.Last in the digital media development was video. YouTube definitely made video sharing a hugely popular form of modern media distribution and this is continuing to grow as we speak today. Now with new technology seen in things like the iPhone,  this new form of virtual medi a  is available in handheld devices as well, and no doubt  this sector  is only going to continue to grow in the future (Rogers 2006). Now that you understand a bit more about the technology side, you may be wondering how it can help your business.Well businesses are using digital media for marketing more and more today, realizing that there is a huge marketing field out there and that  it can help to draw in visitors and can even provide better search engine visibility with you. Text content can be kept updated on your site and helpful content is a great part of good marketing. Expertise in your field can really help your business and get traffic flowing into your business website. Photos, charts, diagrams, and models are always popular online and will help you to get more visibility as well.Audio allows you to use music on pages or to do podcasts for your business. Creating videos is a popular method of digital media marketing today, and videos do very well in search engin es (Rogers 2006). With the popularity of digital media, it is definitely important that you continue to create and use it for good marketing and business results. Even if you have to hire someone to help out, the benefits will make it worth the money. So knowing about and using digital media is definitely important for your business success todayProblem statement: Most people accept the idea that the media can influence people. But the degree of that influence, as well as who is most-impacted, when, how and why, have been the subjects of great debate among communication scholars for nearly a century. Media effects refers to the many ways individuals and society may be influenced by both news and entertainment mass media, including film, television, radio, newspapers, books, magazines, websites, video games, and music.To understand digital media effects, it is first critical to consider how media are used and for what purposes. Communication scholars have traditionally fallen into tw o camps – functionalists, who believe the media audience tends to be in control and active, and critical/culturalists who believe the audience has less control and is therefore more passive. The balance may lie somewhere in the middle and may vary from country to country. Purpose of the study: In this paper we are going to study and evaluate the digital media and its effect on children in general.The following text is a general idea: Youth spend an average of ;7 hours/day using media and the vast majority of them have access to a bedroom television, computer, the Internet, a video-game console, and a cell phone. In this paper we review the most recent research on the effects of media on the behavior and health and well-being of children and adolescents. Studies have shown that media can provide information about safe health practices and can foster social connectedness.However, recent evidence raises concerns about media's effects on aggression, sexual behavior, substance use , disordered eating, and academic difficulties. We provide recommendations for parents, practitioners, the media, and policy makers, among others, for ways to increase the benefits and reduce the harm that media can have for the developing child and for adolescents. More than 50 years of media research attests to the significant influence of media on child and adolescent health.Both â€Å"old† media (television, movies, magazines) and â€Å"new† media (the Internet and social networking sites, video/computer games, cell phones) can have an impact on virtually every health concern that practitioners and parents have about young people, including aggressive behavior, risky sexual behavior, substance use, and disordered eating. Although the media are not the leading cause of any of these problems, the research reviewed here suggests that they are significant.Yet, despite the evidence of potential harm, there is also evidence that media can be beneficial for youth (eg, by increasing empathy and acceptance of diversity through modeling of prosocial behaviors and developing children's early literacy skills through educational programming). Those concerned with child and adolescent health need to be aware of the research on the effects of modern media on youth. Theoretical framework: Literature review: Media affect youth not only by displacing time they spend doing homework or sleeping but also by influencing beliefs and behaviors.According to social learning theory, children and adolescents learn by observing and imitating what they see on the screen, particularly when these behaviors seem realistic or are rewarded. Cognitive development theory asserts that children's cognitive capacities at different stages determine if and how they understand media content. For example, children younger than 8 years who are not yet able to comprehend persuasive intent will be more vulnerable to advertising.In addition, media present youth with common â€Å"scriptsâ €  for how to behave in unfamiliar situations such as romantic relationships. Finally, superpeer theory states that the media are like powerful best friends in sometimes making risky behaviors seem like normative behavior. With the variety of theories suggesting a potentially powerful effect of the media and the growing empirical evidence for negative impact, one might hypothesize that parents would take care to limit exposure to detrimental media content.However, the â€Å"third-person effect† (a well-documented phenomenon in the communications literature) shows that teenagers and adults think that the media influence everyone except themselves or their children Violence and Aggression By the age of 18, the average adolescent will have seen an estimated 200 000 acts of violence on television alone. Much of the violence on television and in movies is presented in a sanitized and glamorized fashion, and in children's programming it often is presented as humorous.More than 1 0% of 10- to 14-year-olds saw 40 of the most violent movies in 2003. Both music videos and rap music have become increasingly violent. Interactive media can encourage antisocial beliefs and behavior in children and adolescents, particularly because violence in new media has been found to be prevalent as well. A recent analysis of video games revealed that more than half of all games contain violence, including ;90% rated as appropriate for children aged 10 years and older.Health professionals worry most about first-person shooter video games. In the aftermath of the West Paducah, KY school shooting, it was discovered that the shooter had never fired a real gun in his life before that day, yet his marksmanship was both accurate and lethal. Researchers believe that repeated exposure to mediated violence can lead to anxiety and fear, acceptance of violence as an appropriate means of solving conflict, and desensitization, with resulting increases in aggression and decreases in altruism. In particular, the portrayal of justifiable violence that is common in American media—â€Å"good guys versus bad guys†Ã¢â‚¬â€places children at risk because it is so powerfully reinforcing. The relationship between media violence and real-life aggression is nearly as strong as the impact of cigarette smoking on lung cancer not everyone who smokes will get lung cancer, and not everyone who views media violence will become aggressive themselves. However, the connection is significant. The most problematic forms of media violence include attractive and unpunished perpetrators, no harm to victims, realism, and humor. SexResearchers investigating the impact of exposure to sexual content in media on adolescent sexual beliefs and early sexual initiation have found modest but significant associations, particularly in the realm of pornography. In a national sample of 1500 10- to 17-year-olds, nearly half of the Internet users had been exposed to on-line pornography in the prev ious year. In a sample of middle-school youth, exposure to sexually explicit (X-rated) content predicted perpetration of sexual harassment (for males), more permissive sexual norms, having oral sex, and engaging in sexual intercourse while in high school.Longitudinal studies now exist that have linked heavy exposure to sexual content in mainstream media with more rapid progression of sexual activity, earlier coital behavior, greater risk for and unplanned pregnancy, and sexually transmitted disease. One explanation for this relationship may lie in the role of the media as a â€Å"superpeer† that gives adolescent audiences a consistent message that sex is normative and risk free. In addition, media play an important role in providing sexual information to adolescents in the United States and in shaping their beliefs about how males and females behave in romantic relationships.Television shows geared toward teenagers actually have more sexual content than adult-oriented shows, yet there is little mention of the need for contraception or for responsibility. Virtually every Western country makes birth control available to adolescents, including allowing birth control advertisements in the media, but the major US television networks balk at airing ads for contraception. This flies in the face of the fact that a substantial body of evidence shows that giving teenagers’ access to condoms does not lead to earlier sexual activity.Parents and child advocates often express concern over children connecting with strangers on-line. Although there have been disturbing cases of Internet sexual predatory activity by adults on children, most recent studies of Internet safety have suggested that sexual solicitation of minors is more likely to occur by other minors. Social networking sites such as MySpace and Facebook enable adolescents to present themselves publicly, sometimes in very sexually suggestive ways; however, adult on-line predators are not using social n etworking sites to find or entice their victims.One national survey of â€Å"sexing† with cell phones, conducted with 13- to 19-year-olds, revealed that 20% had sent and 48% had received sexual messages. However, social networking sites can also be used prosocially for safer-sex campaigns, for example. Substance Use In the United States, more than $22 billion is spent marketing and advertising drugs ($13 billion on tobacco, $5 billion on alcohol, and $4 billion on prescription drugs), and many research studies have shown that it has a significant impact on adolescent use.Children and teenagers can also see considerable alcohol and drug content in on-line videos. Recent studies of social networking sites have found that substance abuse is referenced in 40% of the profiles. Portrayals of tobacco are also prevalent in the movies: ? 70% of movies made in the United States today contains smoking, and smoking is rarely associated with negative health outcomes. Longitudinal prospect ive studies have revealed that exposure to movie smoking at baseline (grades 5–8) predicts smoking initiation 1 to 8 years later.Experimental research has helped illuminate why exposure to movie characters' smoking is associated with smoking initiation: viewers who identify with the storyline and the characters are more likely to increase their intention to smoke. Obesity and Eating Disorders Numerous American and international longitudinal studies (one of them as long as 26 years in duration) have shown that media use is contributing to the current epidemic of obesity worldwide. However, the mechanism for why heavy television-viewing, in particular, is predictive of children's weight status is unclear. Food marketing may be 1 culprit.Children and teenagers see 4400–7600 ads per year for junk food and fast food on television alone. Randomized, controlled experiments have provided evidence that exposure to junk food advertising has an impact on children's food beliefs a nd preferences. The Internet now presents a new concern. As the Kaiser Foundation noted, â€Å"There is a vast amount of food related content online, with the potential to significantly expand and deepen children's exposure to food marketing messages. Apart from the influence of advertising, eating while viewing may lead to greater food consumption.College-aged students showed significantly greater consumption of food when subjects were watching television versus listening to classical music. The investigators hypothesized that satiety cues are suppressed in viewing conditions. Although the evidence that television-viewing displaces physical activity is equivocal, researchers are now examining whether heavy media use, particularly at nighttime, displaces sleep. Children who do not get enough sleep are more likely to engage in sedentary behaviors (such as television-viewing) and less likely to engage in physical activity.The media play a crucial role in the formation of body self-im age and may be responsible for creating unrealistic expectations and body dissatisfaction. Females who are regular readers of fashion and beauty magazines in early adolescence are more likely to suffer from a distorted body image during their teenaged years. A natural field experiment in Fiji revealed that the prevalence of eating disorders increased dramatically after the introduction of American television programs, which show excessively thin female lead characters.On the Internet, there are now ;100 proanorexia Web sites that not only encourage disordered eating but offer specific advice on purging, severely restricting caloric intake, and exercising excessively. School Performance and Learning Problems The possibility of a connection between television-viewing and ADD or other learning disabilities is currently an issue of great controversy. An initial study in 2004 revealed an association between daily hours of television-viewing at the ages of 1 to 2 years and subsequent atte ntional problems at the age of 7.However, a more recent study in which 59 children with ADD and 106 comparison children were examined actually revealed that the latter had more impairment in their cognitive processes after viewing television than the former. At least 4 studies have shown an impact on academic performance, especially if there is a television set in the child's or teenager's bedroom. Other Health Effects Heavy television-viewing has also been associated with hypercholesterolemia, hypertension, an increased prevalence of asthma, sleep disorders, mood disorders, psychological distress, and depression.These were largely correlational studies and, therefore, did not necessarily show cause and effect. Prosocial Effects Despite the negative effects listed above, the media can be powerfully prosocial and educational. Children and teenagers can learn antiviolence attitudes, empathy, tolerance toward people of other races and ethnicities, and respect for their elders. Video ga mes can be beneficial as well, including improving compliance with chemotherapy regimens in adolescents with cancer.Important and useful public messages can be successfully embedded into primetime television shows that are popular with adolescents. In an episode of the television program Friends, for example, Rachel tells her boyfriend Ross that she is pregnant although they had used a condom. A national telephone survey conducted with Friends viewers after the episode aired found that adolescents learned that condoms are not fool-proof and were more likely to discuss contraception with their parents.Similarly, a recent episode of Gray's Anatomy was effective in teaching viewers about HIV and pregnancy. Research into the impact of digital media on relationship formation and maintenance has revealed that on-line communication and on-line self-disclosure can stimulate adolescents' social connectedness and, thereby, their well-being. However, the benefits of socializing on-line are not equal for every child or adolescent. The positive Internet effect holds only when adolescents predominantly talk with their existing friends.Communication technologies that are most often used to communicate with strangers (eg, chat in a public chat room) or more solitary forms of Internet use (such as surfing the Web) have negative effects on social connectedness. TRADITIONAL MEDIA AND NEW MEDIA Children and adolescents spend more time with media than they do in any other activity except for sleeping—an average of ;7 hours/day. Children's bedrooms are replete with media technology: by 2005, two thirds had a television set, one half had a VCR or DVD player or video-game console, and nearly one third had Internet access or a computer.Media impact is increased significantly with the presence of a bedroom television: viewing increases 1 to 2 hours/day, risk of overweight increases by 31%, and the likelihood of smoking doubles. When a television is in the bedroom, parents are le ss able to monitor viewing habits , children participate in fewer activities such as reading and hobbies, and sleep is shortened Field Observation: Focus group: One of the aims of my research paper was to understand what children feel about the way they are affected by the Digital media. To do this i used one of our qualitative methods – focus group.A focus group is a method that is used by researchers to find out what people’s opinions and views are. During a focus group the researcher(s) will ask questions to stimulate discussion within the group, while taking note of what people are saying about particular issues. The focus group were conducted in Notre dame college-lwaize in total, 10 young people (5 males and 5 females) took part, who were all aged between 9 – 12year. Question asked during the focus group: * Do Digital media take a lot of your time? * Do you feel lost when you are not connected? Do you go online to check for new updates? * Do you feel you a lways have to go online to learn/view information? * Do you forget to eat when you are connected? * Do you use online social networking to retrieve any type of information? * Does spending time on social networking affects on your grades in a negative way? * Do you think you can stop yourself from always connecting online? * Are you unable to continue your day without checking for updates of news / friends online? * Has social networking sites made you become depressed? Do you enter sexual websites? * Do you talk with stranger people online? Analysis: After the focus groups were done, the information was analyzed and i was able to put together the information to have a basic result. I can say that each person had his/her own view, the information was not possible to evaluate and conduct on a percentage scale. The focus group study it showed that the males spend more time on social networking sites then men. They believe they do spend more time online which allows them to play ad ent er many kind of websites.All participants believe online social networking is time consuming and has its negatives. Some of the negatives given about online social networking. Some positives were: it has allowed a number of people to be curious to want to know more information, to learn more, to be able to communicate with people in different countries and be entertained. Solution and recommendation: Parents should limit total screen time for children older than 2 years to no more than 1 to 2 hours/day, and avoid screen time for children younger than 2 years.Also keep children's bedrooms free of screen media; and co-view media with their children and discuss the content.. Parents also need to avoid exposing young children to PG-13– and R-rated movies, given the prevalence of violent and sexual content in higher-rated film sand the new evidence that movie scenes that depict drinking alcohol and smoking may be very influential in teenagers' decisions to use alcohol and tobacco. In addition, parents can be mindful of their own media practices, because studies have shown that the strongest predictor of children's heavy media use is parents' heavy media use.Parental efforts to interpret, elaborate, and provide supplemental information on topics introduced by television have been found to be successful in countering negative or harmful content. In a recent study on exposure to sexual media content, adolescents who report that they discuss the content of what they see on television are less likely to engage in risky sexual activity. Moreover, Schools have not kept pace with modern media, especially in violence prevention, drug prevention, and sex education programs.With the amount of sexual suggestiveness currently displayed on television and in movies, schools no longer have any excuse for not providing comprehensive school-based sex education programs for children and adolescents, including full discussions of contraception and discussions of how sex and sex uality are portrayed in the media. Similarly, drug education programs must progress beyond scare tactics to incorporate principles of media education, teaching young people how to deconstruct alcohol and tobacco ads and, therefore, become more resilient.Conclusion: During the past 50 years, thousands of research studies have revealed that the media can be a powerful teacher of children and adolescents and have a profound impact on their health. To date, too little has been done by parents, health care practitioners, schools, the entertainment industry, or the government to protect children and adolescents from harmful media effects and to maximize the powerfully prosocial aspects of modern media. More research is needed, but sufficient data exist to warrant both concern and increased action.

Substance Use In the United States, more than $22 billion is spent marketing and advertising drugs ($13 billion on tobacco, $5 billion on alcohol, and $4 billion on prescription drugs), and many research studies have shown that it has a significant impact on adolescent use.Children and teenagers can also see considerable alcohol and drug content in on-line videos. Recent studies of social networking sites have found that substance abuse is referenced in 40% of the profiles. Portrayals of tobacco are also prevalent in the movies: ? 70% of movies made in the United States today contains smoking, and smoking is rarely associated with negative health outcomes. Longitudinal prospect ive studies have revealed that exposure to movie smoking at baseline (grades 5–8) predicts smoking initiation 1 to 8 years later.Experimental research has helped illuminate why exposure to movie characters' smoking is associated with smoking initiation: viewers who identify with the storyline and the characters are more likely to increase their intention to smoke. Obesity and Eating Disorders Numerous American and international longitudinal studies (one of them as long as 26 years in duration) have shown that media use is contributing to the current epidemic of obesity worldwide. However, the mechanism for why heavy television-viewing, in particular, is predictive of children's weight status is unclear. Food marketing may be 1 culprit.Children and teenagers see 4400–7600 ads per year for junk food and fast food on television alone. Randomized, controlled experiments have provided evidence that exposure to junk food advertising has an impact on children's food beliefs a nd preferences. The Internet now presents a new concern. As the Kaiser Foundation noted, â€Å"There is a vast amount of food related content online, with the potential to significantly expand and deepen children's exposure to food marketing messages. Apart from the influence of advertising, eating while viewing may lead to greater food consumption.College-aged students showed significantly greater consumption of food when subjects were watching television versus listening to classical music. The investigators hypothesized that satiety cues are suppressed in viewing conditions. Although the evidence that television-viewing displaces physical activity is equivocal, researchers are now examining whether heavy media use, particularly at nighttime, displaces sleep. Children who do not get enough sleep are more likely to engage in sedentary behaviors (such as television-viewing) and less likely to engage in physical activity.The media play a crucial role in the formation of body self-im age and may be responsible for creating unrealistic expectations and body dissatisfaction. Females who are regular readers of fashion and beauty magazines in early adolescence are more likely to suffer from a distorted body image during their teenaged years. A natural field experiment in Fiji revealed that the prevalence of eating disorders increased dramatically after the introduction of American television programs, which show excessively thin female lead characters.On the Internet, there are now ;100 proanorexia Web sites that not only encourage disordered eating but offer specific advice on purging, severely restricting caloric intake, and exercising excessively. School Performance and Learning Problems The possibility of a connection between television-viewing and ADD or other learning disabilities is currently an issue of great controversy. An initial study in 2004 revealed an association between daily hours of television-viewing at the ages of 1 to 2 years and subsequent atte ntional problems at the age of 7.However, a more recent study in which 59 children with ADD and 106 comparison children were examined actually revealed that the latter had more impairment in their cognitive processes after viewing television than the former. At least 4 studies have shown an impact on academic performance, especially if there is a television set in the child's or teenager's bedroom. Other Health Effects Heavy television-viewing has also been associated with hypercholesterolemia, hypertension, an increased prevalence of asthma, sleep disorders, mood disorders, psychological distress, and depression.These were largely correlational studies and, therefore, did not necessarily show cause and effect. Prosocial Effects Despite the negative effects listed above, the media can be powerfully prosocial and educational. Children and teenagers can learn antiviolence attitudes, empathy, tolerance toward people of other races and ethnicities, and respect for their elders. Video ga mes can be beneficial as well, including improving compliance with chemotherapy regimens in adolescents with cancer.Important and useful public messages can be successfully embedded into primetime television shows that are popular with adolescents. In an episode of the television program Friends, for example, Rachel tells her boyfriend Ross that she is pregnant although they had used a condom. A national telephone survey conducted with Friends viewers after the episode aired found that adolescents learned that condoms are not fool-proof and were more likely to discuss contraception with their parents.Similarly, a recent episode of Gray's Anatomy was effective in teaching viewers about HIV and pregnancy. Research into the impact of digital media on relationship formation and maintenance has revealed that on-line communication and on-line self-disclosure can stimulate adolescents' social connectedness and, thereby, their well-being. However, the benefits of socializing on-line are not equal for every child or adolescent. The positive Internet effect holds only when adolescents predominantly talk with their existing friends.Communication technologies that are most often used to communicate with strangers (eg, chat in a public chat room) or more solitary forms of Internet use (such as surfing the Web) have negative effects on social connectedness. TRADITIONAL MEDIA AND NEW MEDIA Children and adolescents spend more time with media than they do in any other activity except for sleeping—an average of ;7 hours/day. Children's bedrooms are replete with media technology: by 2005, two thirds had a television set, one half had a VCR or DVD player or video-game console, and nearly one third had Internet access or a computer.Media impact is increased significantly with the presence of a bedroom television: viewing increases 1 to 2 hours/day, risk of overweight increases by 31%, and the likelihood of smoking doubles. When a television is in the bedroom, parents are le ss able to monitor viewing habits , children participate in fewer activities such as reading and hobbies, and sleep is shortened Field Observation: Focus group: One of the aims of my research paper was to understand what children feel about the way they are affected by the Digital media. To do this i used one of our qualitative methods – focus group.A focus group is a method that is used by researchers to find out what people’s opinions and views are. During a focus group the researcher(s) will ask questions to stimulate discussion within the group, while taking note of what people are saying about particular issues. The focus group were conducted in Notre dame college-lwaize in total, 10 young people (5 males and 5 females) took part, who were all aged between 9 – 12year. Question asked during the focus group: * Do Digital media take a lot of your time? * Do you feel lost when you are not connected? Do you go online to check for new updates? * Do you feel you a lways have to go online to learn/view information? * Do you forget to eat when you are connected? * Do you use online social networking to retrieve any type of information? * Does spending time on social networking affects on your grades in a negative way? * Do you think you can stop yourself from always connecting online? * Are you unable to continue your day without checking for updates of news / friends online? * Has social networking sites made you become depressed? Do you enter sexual websites? * Do you talk with stranger people online? Analysis: After the focus groups were done, the information was analyzed and i was able to put together the information to have a basic result. I can say that each person had his/her own view, the information was not possible to evaluate and conduct on a percentage scale. The focus group study it showed that the males spend more time on social networking sites then men. They believe they do spend more time online which allows them to play ad ent er many kind of websites.All participants believe online social networking is time consuming and has its negatives. Some of the negatives given about online social networking. Some positives were: it has allowed a number of people to be curious to want to know more information, to learn more, to be able to communicate with people in different countries and be entertained. Solution and recommendation: Parents should limit total screen time for children older than 2 years to no more than 1 to 2 hours/day, and avoid screen time for children younger than 2 years.Also keep children's bedrooms free of screen media; and co-view media with their children and discuss the content.. Parents also need to avoid exposing young children to PG-13– and R-rated movies, given the prevalence of violent and sexual content in higher-rated film sand the new evidence that movie scenes that depict drinking alcohol and smoking may be very influential in teenagers' decisions to use alcohol and tobacco. In addition, parents can be mindful of their own media practices, because studies have shown that the strongest predictor of children's heavy media use is parents' heavy media use.Parental efforts to interpret, elaborate, and provide supplemental information on topics introduced by television have been found to be successful in countering negative or harmful content. In a recent study on exposure to sexual media content, adolescents who report that they discuss the content of what they see on television are less likely to engage in risky sexual activity. Moreover, Schools have not kept pace with modern media, especially in violence prevention, drug prevention, and sex education programs.With the amount of sexual suggestiveness currently displayed on television and in movies, schools no longer have any excuse for not providing comprehensive school-based sex education programs for children and adolescents, including full discussions of contraception and discussions of how sex and sex uality are portrayed in the media. Similarly, drug education programs must progress beyond scare tactics to incorporate principles of media education, teaching young people how to deconstruct alcohol and tobacco ads and, therefore, become more resilient.Conclusion: During the past 50 years, thousands of research studies have revealed that the media can be a powerful teacher of children and adolescents and have a profound impact on their health. To date, too little has been done by parents, health care practitioners, schools, the entertainment industry, or the government to protect children and adolescents from harmful media effects and to maximize the powerfully prosocial aspects of modern media. More research is needed, but sufficient data exist to warrant both concern and increased action.
