Nutrition Food Essay In our today’s society, especially western countries, the issue of fast food seems to be at the top of every health related debate. As these debates become more controversial, the question of who bears the responsibility remains unanswered. In his essay, Don’t Blame the Eater, David Zinczenko attempts to answer this key question by placing the greater responsibility of America’s obesity and other fast food related health issues on the fast food industries. Contrary to Zinczenko’s argument, Raldy Balko, in his essay, What You Eat Is Your Business, states that, people should take ownership of their health and well-being, and are therefore responsible for what and how they eat. Although both Zinczenko and Balko address the issue of responsibility, though with contrast, but valid arguments, Zinczenko seems to present a more convincing argument due to the way in which he explains the politics of food, the way in which our lifestyles are altered by what we eat, and things we can do to change the way we see food and its role in our lives. Although Zinczenko hold consumers responsible to an extent, he blames the fast food industries for the rising rate of obesity and other health issues related to fast food due to their failure to provide labels for their products. Zinczenko convincingly supports his claim by noting statistical data that shows the rise in money spent to treat diabetes. â€Å"Before 1994, diabetes in children was generally caused by a genetic disorder only 5 percent of childhood cases were obesity related, or Type 2 diabetes. Today, according to the National Institutes of Health, Type 2 diabetes accounts for at least 30 percent of all new childhood cases of diabetes in this country†(Zinczenko 392). He argues that, if the fast food companies are regulated so that they are responsible for their food contents, by providing proper labels, than consumers will make informed food choices. Contrary to Zinczenko, Balko argues that what one eats should be a matter of personal responsibility. To Balko’s credit, I believe that people should take personal responsibility for their health by adding a sensible diet and exercise to their routines. Where I differ from Balko is when he says that government restrictions on food are a result of people making poor food choices. According to Balko, â€Å"a society where everyone is responsible for everyone else’s well-being is a society more apt to accept government restrictions† (397). I think Balko’s argument in this regard, is a selfish one, and is an attempt to exempt the rich from paying their fair share of taxes that would otherwise benefit the poor or some middle families who cannot afford the high cost of health insurance. Both Zinczenko and Balko seem to agree on the rising health costs that are somehow a result of fast food, these two authors seem to differ on reasons. Zinczenko argues that health care cost is on the rise because of diseases caused by fast food due to the failure of fast food companies to provide labels and that consumers should not be blame for it. However, Balko argues that it is so that, we allow the â€Å"government to come between us and our waistline† (396). Balko states that, the more the government continues to fund health issues that are direct attribute of poor food/health choices, the more people will continue to dine on fast food and engage not in an effective diet and exercise regimen. (398) The growth of the fast food industry and the rate at which fast food is consumed is so fast, and its accompanying risks of obesity and related cardiovascular diseases have become a societal epidemic. Zinczenko blames the fast food industries for the spring in the rate to which obesity have grown in the United States. Even though Zinczenko is right about the rising rate of obesity, and that the consumption of fast food forms part of its etiology, the thesis of his argument cannot be proven and therefore cannot form the basis for his claims against the fast food companies since there are other contributing factors regarding the cause, onset, and progression of obesity. Obesity is also biologically linked. These biological attributors include: genetics, hormones, enzymes, and vitamins and minerals. Some people have fat in their genes that, no matter what they do, they are just fat. Others have issues with hormonal imbalances and or inadequate enzymatic actions that would aid in the adequate digestion and absorption of certain foods. Fast food is just one of the many environmental attributes associated with obesity. So Zinczenko can accurately make his case against the fast food industries for providing labels so as to enable consumers make informed food choices and not a case of obesity. Sometimes, people are too fast to pass judgment on others, especially people that are obese. I am equally guilty of the accusation myself. I work as a nurse at a nursing home facility and, in most cases, when staff member comes to me complaining of headache, first thing I say to them is; let’s check your blood pressure and, God forbid, the blood pressure is elevated, or if that person just look fat to me, my next comment is, it is because of all the junk you eat. My judgment, though may be incorrect, is based on the fact that most of these staff members are single parents, live in inner cities, and have a total commute time of two hours to and from work. Not to mention, some of them have more than one job. However, these people are being made to feel guilty about something that is totally out their control. In most instances, their wages aren’t even enough to meet up with their rents and utilities bills. Fast food comes handy in such instance where one can spend ten dollars and get ten cheeseburgers to feed a family of three to five versus going to the grocery store where each healthy ingredient is almost equivalent to the price of the entire dinner comprising of fast food. People fall back on fast food because it is cheap. Zinczenko explains that his parents were split up and that he had to live with his mother who worked long hours just to make the monthly bills. â€Å"Lunch and dinner, for me, was a daily choice between McDonald’s, Taco Bell, Kentucky Fried Chicken or Pizza Hut. † (Zinczenko 391). In Zinczenko’s case, his lifestyle is altered because fast food is his only option since his family is dysfunctional. His single mother has to work very hard to pay bills and provide him a meal. It doesn’t matter the kind of meal. A meal is a meal, especially for someone who doesn’t have the time to prepare a home cooked meal. The people afflicted with fast food related obesity are not to blame for what they eat because they have very little or no options regarding what they eat due to all of the above reasons. However, to Balko’s point, while people may not have the option about what they eat, they have the option to control how they eat. Zinczenko states in his essay that fast food is â€Å"the only available options for an American kid to get an affordable meal†, and so, he urges his readers not to â€Å"blame the Eater† (392). But as with Zinczenko, we are well aware of the role fast food play in our lives. We understand that, though fast may be one, or the only available meal choice that we have, the way we eat can help us determine the role these foods play in our lives. Zinczenko supports his argument about the role food play in his life by giving information about his pre-college weight. â€Å"By age 15, I had packed 212 pounds of torpid tallow on my once lanky 5-foot-10 frame† (392). Even Zinczenko believes that, consumers are as equally responsible for the way they eat. However, he maintains his argument that the fast food companies bare the greater responsibility. In conclusion, both the eater and the producer are responsible for fast food related obesity, but I believe that the fast industries should bare the greater responsibility. Fast food companies must provide their consumers with proper food labels that enable them to make inform decision about what they eat. Label should not be falsified or misleading, like in the example giving by Zinczenko about the misleading label on the â€Å"chicken salad† (393). He refers to the salad as not healthy and that it is a caloric death- trap aimed at eaters who will not suspect it. Although Balko makes some really good points, his objectives seem to me as a means to an end. Zinczenko cautions that there are few or no alternatives to what we eat and that things have to change. Balko cautions that allowing food regulations for labels means letting the government between you and your waistline. In either case, we as a people have a responsibility to consider what and how we eat.

Treatise for the Christian Soldier in John Milton’s Paradise Lost Essay

Milton's Treatise for the Christian Soldier in Paradise Lost  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚         While the War in Heaven, presented in Book VI of John Milton's Paradise Lost, operates as a refutation of the concept of glory associated with the epic tradition, the episode also serves a major theological purpose. It provides nothing less than a perfect example of how the Christian soldier should act obediently in combating evil, guarding against temptation, and remaining ever vigilant against the forces of darkness. It also offers the ultimate hope that Satan can be thwarted and comforts Christians in the knowledge that Satan cannot be victorious. At the same time, the example warns against the pretensions that Christians might have about being able to overcome Satan by themselves. Christians are reminded that the victory can only be won by the Son of God; at best, they can only confirm their allegiance and obedience to God through their service. Throughout the poem Milton has tried to show two definitions of glory. The first lies in the assumption that war can bring glory to those who perform heroic deeds in its service. This is the view Satan holds, and is evidenced in his words to Abdiel, "But well thou com'st / Before thy fellows, ambitious to win / From me some plume" (vi, 159-161). The second defines glory not as something won, but something given. The Son affirms this definition when he explains to the loyal angels why he alone must end the war: "against me is all their rage, / Because the Father, to whom in Heaven supreme / Kingdom and power and glory appertains, / Hath honored me, according to his will" (vi, 813-816). James Holly Hanford perhaps best describes the conflicted feelings Milton had for war: War, then constituted for Milt... ...on's example and by Milton's manipulation of the elements of the epic tradition. For Milton, putting down the epic tradition in favor of Christian doctrine exemplifies his thoughts on war. As a realistic pacifist, Milton saw war as the result of sin, but knew that because of the presence of sin in a post-lapsarian world, war on earth would only be ended by the Son, just as he ended it in Heaven.

Stress in Athletics Essay examples -- Sports Athletics Athletes Teams

Stress in Athletics In the Journal article by Mark H. Anshel, entitled Qualitative Validation of a Model For Coping With Acute Stress In Sports. Explains how stress affects athletes, and how they can go about to deal with the problem, or cope with the problem. The author breaks this down into four categories. First, they want to perceive a stimulus or experiencing an event, secondly, appraising that event as stressful, thirdly, using either approach or avoidance coping strategies each consisting of either cognitive or behavioral strategies, and finally enacting post-coping activity that consists of either remaining on task, reappraising the stressful situation, examining the effectiveness of the coping strategy, or disengaging from further sport participation. Stress itself is a widely studied characteristic; it is defined as an interaction between an individual and the surrounding environment. Most research on stress is just new, but has been a topic for the last 20 years. But most new studies on stress have to deal more with the coping process. â€Å"Coping is the person’s conscious attempt at reducing or managing the demands of a stressful event or expanding the person’s resources to deal with the event (Anshel, 2001).† Previous research by Gottlieb (1997) explained â€Å"how coping strategies related to acute forms of stress differ from chronic stress, and that many contexts of chronic stress do not end themselves to an event-centered strategy of measuring coping (pg...

Media Ethics Towards Employing Utilitarianism and Kantian Theory in Examining Practical Ethical Issues

Media Ethics Towards Employing Utilitarianism and Kantian Theory in Examining Practical Ethical Issues In this era of global interactivity and extreme media scrutiny, real-life situations and instances of behaviour that raise ethical issues and moral dilemmas continue to reverberate across all civilizations in the world. The role of the media in disseminating information to people is legion, but arising ethical issues persist to put this important institution in a collision course with germane issues that must be primarily dealt with for responsible practice (Plaisance, 2009).Advertising We will write a custom essay sample on Media Ethics: Towards Employing Utilitarianism and Kantian Theory in Examining Practical Ethical Issues specifically for you for only $16.05 $11/page Learn More These ethical issues put into perspective the need to rely on philosophical thought to decide on the proper course of action. It is the purpose of this paper to utilize both utilitarianism and Kantian theory to critically examine some underlying ethical issues relating to the cla im below: There’s almost no situation in which I’d stop filming to do something, because I think a film record of a given situation is ultimately more effective, and has greater impact. In the end, it helps more people than if I put down my camera to lend a hand (Bowden, 1987 p. 182) To offer a critical evaluation of the above claim, it is imperative to briefly discuss the two broad classifications of philosophical thought from which utilitarianism and Kantian theory derives from. The first classification – teleological ethics – comprise of theories which are essentially concerned with outcomes or consequences and the capacity to produce the best possible decisions. These theories are glued by the premise that ethically right decisions are those that produce maximum consequences (Albarran, 2010). To date, utilitarianism, with its axiom of the greatest good still offers the best example of teleological ethics. The second classification – deontologic al ethics – comprise of ethical theories concerned with the philosophical process of arriving at decisions based on established principles (Albarran, 2010). These theories affirm that the rightness or wrongness of an action or behaviour is dependent on that particular action or behaviour and not on the outcomes or consequences it produces. Deontological ethics are best illustrated in the philosophical works of Kant. Utilitarianism, espoused by such philosophers as David Hume, John Stuart Mill, and Jeremy Bentham, among others, states that moral actions are correct to the extent that they tend to enhance the ‘greatest good for the greatest number.’ As one of the best known adaptations of consequentialism, this theory defines what is morally acceptable in terms of the â€Å"maximization of the net expected utility for all parties affected by a decision or action† (Smart Williams, 1998 p. 83).Advertising Looking for essay on communications media? Le t's see if we can help you! Get your first paper with 15% OFF Learn More In other words, human beings ought to behave or act in a manner that occasion the best possible outcomes from their actions (Russo, n.d.). Consequently, acceptable behaviour or actions, according to utilitarianism, should be evaluated by rules and guidelines that, if universally followed would lead to the greatest happiness for the greatest number. Judging by the above description, it appears that the author of the claim in discussion based his arguments on utilitarian theory. Indeed, he argues that a film record of a situation is eventually more effective, has a greater impact, not mentioning the fact that it helps more people. In essence, the film record will enhance the greatest good for the greatest number of viewers the scenario that was being filmed notwithstanding. Such philosophical thought has serious ethical undertones since it therefore means that it actually does not concern us what kind of behaviour or actions we engage in or what our intentions are when engaging in them, as long as the outcomes of our behaviours or actions are generally positive to the wider audience. According to Russo (n.d.), â€Å"†¦what all utilitarians have in common is that they accept one and only one principle of morality, the principle of utility, which states that in all our actions we must always strive to produce the greatest possible balance of good and evil† (para. 3). This therefore means that when faced with a choice between two divergent courses of action, a utilitarian will always aim to select the one that bears the best overall outcome or consequence for the majority who might be affected in one way or another by the actions. In the claim, it is clearly evident that the author would choose the action that has a greater impact and helps more people – that of continuing to film instead of lending a hand. Again, this has serious ethical undertones assuming that the situation he is filming demands that people offer assistance such as a plane clash. Many modern institutions, including the media and democratic institutions, are built around the principle of utilitarianism, that is, ‘the end justify the means.’ Indeed, actions are judged based on the outcomes, not on the objectives, intentions or motives (Terrall, 2007). As such, the individual would be justified to continue filming since he is bound to achieve the best possible outcomes from his action – that of assisting more people. To argue along this continuum, however, is counterintuitive since such actions are taken more for profit orientations than for ethical considerations. When evaluated under the lenses of ethical considerations, utilitarianism in contemporary institutions, including the media, justifies the treatment of individuals as a means to an end. There arise serious ethical connotations when individuals are viewed as a means to achieve an outcome th at is agreeable to the majority.Advertising We will write a custom essay sample on Media Ethics: Towards Employing Utilitarianism and Kantian Theory in Examining Practical Ethical Issues specifically for you for only $16.05 $11/page Learn More In equal measure, ethical issues arise if individuals assume that an action or behaviour is acceptable if it generates a greater sum of good than evil for all the individuals who are affected by such an action (Russo, n.d.). This, it appears, is the mentality of the individual who continues to film since filming by itself will have a greater impact and will assist many people than helping the situation. As already mentioned elsewhere, Kantian theory is firmly rooted in deontological ethics. Kant proposed an intricate system that specified the duties endowed upon us as moral agents. According to Plaisance (2009), â€Å"†¦at the core of [Kant’s] system is the claim that our human capacity for reason enables us to know these duties and that freedom enables us to act on them (p.8). As such, the foundations of Kantian theory are rationality and liberty. For Kant, individuals are bound by obligation to act and behave morally as the only way to perform their duties to others. It is imperative to note that by moral action, Kant insinuated that individuals should test and evaluate their actions by inquiring if they could be universalized, that is, whether it would be morally acceptable if every individual applied the actions as standard of behaviour (Johnson, 2008). It therefore follows that the individual in the filming claim would have first stopped to ponder if it was agreeable for everyone to continue filming the arising situations as opposed to lending a hand. In fact, he would have never at the first place been so sure to say that ‘there’s almost no situation in which I’d stop filming to do something†¦Ã¢â‚¬â„¢ since he was not in a position to know or judge if such an action could be universalized to others in similar profession or situation. This demonstrates why Kant was so strict on rationality and liberty. In a hypothetical situation, say a car accident where people are trapped inside the car, a Kantian follower would have reasoned out to first cease filming and lend a hand. If the situation was not that serious, a Kantian follower would have taken the liberty to start filming the situation. Here, the Kantian theory appears more ethically acceptable. Kant formulated the famous ‘categorically imperative’ phrase, implying duty without exception (Plaisance, 2009). This principle demands obedience and core moral obligations that all individuals must meet. Consequently, Kant was of the opinion that individuals are owned respect not because of their professions or individual positions, but for the reason that they are human beings with ability to reason.Advertising Looking for essay on communications media? Let's see if we can help you! Get your first paper with 15% OFF Learn More According to Plaisance (2009), â€Å"†¦this universal moral obligation requires that we treat individuals as ends in themselves and never sorely as a means to attain other goals or desires we may have† (p.9). In equal measure, the philosopher was of the opinion that morality was principally about motives. To him, motives are the basis of actions and these, not results or consequences – should be the basis for ethics. Back to the filming claim, it is vehemently clear that the individual use the means (situations) to achieve the ends (having a greater impact and assisting more people). The Kantian theory, however, is clear that the individuals should be perceived and treated as the ends in themselves and never sorely as means. Here, the underlying ethical issue is that utilitarianism, its axiom of achieving the greatest good notwithstanding, is open to abuse in contemporary times. In media institutions, indeed, it is rightfully or wrongfully used and depicted as bei ng in the ‘public interest,’ and in the case of newspapers, it is being used and passed as ‘what the public is interested in.’ Such catchy phrases have serious ethical undertones since what one segment of the public is interested in may not be universalized to the other population, not mentioning the fact that the motive behind an action, say publishing a story, may not necessarily be the reason why a certain outcome is desired (Elder, 2001). All in all, both utilitarianism and Kantian theory have been discussed at length in relation to the claim about filming. Ethical issues have been highlighted on both sides and critical appraisal offered. What is clear is that although the claim about filming is utilitarian in nature, utilitarianism raises more ethical issues than Kantian theory. Both philosophical thoughts, however, have their advocates and critics, and it is premature to discount utilitarianism is a valid theory of ethics. Indeed, according to Terrall (2007), many modern institutions, including the media, heavily rely on utilitarianism. However, as have already been discussed, the theory has serious ethical ramifications when compared to Kantian theory. List of References Albarran, A.B (2010). Management of Electronic Media.

Byzantine Music And Christianity Religion Essay Essays

Byzantine Music And Christianity Religion Essay Essays Byzantine Music And Christianity Religion Essay Paper Byzantine Music And Christianity Religion Essay Paper The methodological analysis I used for my undertaking was some old books and that analyse the three notation systems of Byzantine music. Through those books it was able for me to understand better how the two old notation systems worked and why the New Chrysantine method was the 1 that Christian church still uses. In order to happen the right books I visitedA theA ArchdioceseA ofA my countryA andA I found the right people who address whatA booksA areA suited forA my undertaking and besides if those resources are dependable. For my research I used besides questionnaires because they provide a convenient manner of garnering information from people who deals with Byzantine Music as instructors, Chanters, and pupils. I design a short and simple questionnaire so it holds the respondent s involvement. The end was to do the respondent want to finish the questionnaire. In my questionnaires I had some inquiries about the old Notation systems but besides the new system but besides I had inquiries about their sentiment about Byzantine music and why the Christian Orthodox church is still uses it. Questionnaires were a method that helped me a batch for conclude my consequences and results because the sentiments and besides the cognition of those people was really of import. Internet research was besides a method that I used. Internet, in our yearss is a topographic point that person can happen a broad scope of information. I used specific articles and web pages which I knew that are first of all dependable beginnings. For illustration I used web sites that I knew the certificates of the writer or websites that are merely for Educational proposes as www.grovemusic.com. In the cyberspace I besides found old undertakings from academic people and people who are experts in Byzantine music. Finally I used Byzantine tonss, tabular arraies, entering and Videos in order to understand how Byzantine notations systems plants, but besides to used them as illustrations in my undertaking. Introduction The Roman Empire was divided in Eastern and Western in the late of fifth Century. Byzantium was the capital metropolis of Easter Roman Empire since King Constantine rebuilds the Constantinople, in 330 A.D until 1453 when Ottomans Turks took the City from the Romans. The Eastern Roman Empire survived until 1453 as the Grecian speaking-Byzantine Empire. Byzantine music, took its name from the modern bookmans depicting the Christian Orthodox church music of the Eastern countries of the Roman Empire and besides the tunes from verse forms in honor of the King. The height of Byzantine music starts from the early old ages of Christianity and includes chants and anthem which entreaty to God. Byzantine music plays a important function in Christian church and that is the ground that I want to analyze and compose about it. In my undertaking I am traveling to give a short description of Music and Christianity but besides a description about the first two notation systems of Byzantine music ; and how they work through the analysis of specific tonss. Besides through of tabular arraies I will explicate the tonic system of Byzantine music and the anthem, and chiefly I will concentrate on the new Byzantine notation system or else the Chrysanthosnotation system. I will besides advert the advantages and disadvantages of the three systems of the Byzantine music, and eventually I will compose some consequences and Outcomes through, my survey of Byzantine music. Chapter I BYZANTINE MUSIC AND CHRISTIANITY The metropolis of Byzantium is the country which is in the present called Constantinople. It was rebuilt by Constantine in 330 A.D and was made the capital metropolis of the Eastern Roman Empire. Christianity was besides accepted by the imperial household in the twelvemonth of 312 A.D. However this caused a major rake between the Orthodox people. During the twelvemonth of 395 A.D, they were divided into two imperiums, the Eastern and Western. Each imperium though maintained a different capital metropolis, the Eastern with the Byzantium and the Western with Rome. Consequently the Christian church so adapted features from the Greek speech production universe and other Greek communities which were around the Eastern Mediterranean. As I mentioned earlier, Byzantine music has to make with church music merely. In an cyberspace article for Byzantine music , the writer Dimitri Conomos references that Byzantine music is the medieval sacred chant of Christian Churches following the Orthodox rite. By stating Byzantine Music that includes the anthem, chants and all of their derived functions which have to make with Christianity and chiefly to God, the Son of God, the Virgin Mary and the Saints of Christian churches. Most hymns and psalms describe the life, miracles and the passions of Jesus Christ every bit good as the Saints . David J. Melling, in the internet article of Reading Psalmodia , references that: When Christianity was established as the official faith of the Roman Empire the Church acquired new and glorious edifices for worship. The rites and ceremonials of Imperial Christianity took on the sedateness and the magnificence of tribunal ritual. A rich traditions of hymnography developed, poets, composers and vocalists conveying their accomplishments to the service of the Church. During the first old ages of Christianity the church male parents did non accept the usage of musical instruments holding anything to make with the Church. As Constantinos G. Eliades references in I?I µI »I µI„I ®I?I ±I„I ± I’I†¦I ¶I ±I?I„I?I?I ®I‚ II?I?I »I ·I?I?I ±I?I„I?I?I ®I‚ I?I?I†¦I?I?I?I ®I‚ ( Studies of Byzantine Ecclesiastical Music ) , they believed that the instrumental music was improper and inappropriate for the Orthodoxy. Even though music has the ability to do you experience rather strong feelings, it is felt even more in Christianity because it is the manner in which we can talk to God. However St. Ignatius wrote to the Church in Ephesus in order to do a alteration. His precise words are in an article in an internet web site: You must every adult male of you to fall in in a choir so that being harmonious and in Concord and taking the keynote of God in unison, you may sing with one voice through Jesus Christ to the Father, so the He may hear you and through your good workss recognize that you are parts of His Son . Grigorios Th. Stathis besides mentions in I- I’I†¦I ¶I ±I?I„I?I?I ® I?I?I†¦I?I?I?I ® I?I„I · I »I ±I„I?I µI?I ± I?I ±I? I?I„I ·I? IIˆI?I?I„I ®I?I · , ( Byzantine music in faith and scientific discipline ) , that the usage of music in the church can assist in the approval of people s psyches and a vocal of the church can be associated with coming and praying. Church music is rather a important and serious affair with a true significance for the Christian population. In a Byzantine music cyberspace article, written by Mavraganis Diamantis, he mentions that Byzantine music is considered to be in a manner the continuity of the ancient Grecian music. He states that many characteristics which can be found in ancient Grecian music, such as the graduated tables, the sounds, and the systems are quite common with those found in Byzantine music.

Eliades, references that the ancient Grecian music every bit good as the antediluvian Grecian linguistic communication were the first which were used by the Orthodox Church. With the birth of Jesus Christ followed with the spread of Christianity, Greek music easy became known beyond the parturiency of the Grecian universe and moved to the Holy Places and countries of the Byzantine Empire. There, Grecian music was able to spread out, better, develop, since it was affected by different beginnings. Finally it turned into being a wholly s ecclesiastical type music which serves in a manner the spiritual Orthodox people. The grounds why the music of Christianity was Greek are many. Harmonizing to Constantinos G. Eliades, in I?I µI »I µI„I ®I?I ±I„I ± I’I†¦I ¶I ±I?I„I?I?I ®I‚ II?I?I »I ·I?I?I ±I?I„I?I?I ®I‚ I?I?I†¦I?I?I?I ®I‚ ( Studies of Byzantine Ecclesiastical Music ) , some of these grounds are the undermentioned: to get down with all the music has characteristics which originated in Greece, for illustration the half steps every bit good as the systems which were found by Pythagoras the celebrated Grecian Mathematician. Another ground is that the music of the church was written based on the beat of the anthem which was the characteristic beat used in ancient Grecian music. The writer states that this happened because the instrumentalists were either Greeks or they had known ancient Grecian music really good. Chapter two The Byzantine anthem and the different sorts of them The anthem to God were considered to be the oldest musical act towards Him. The Eastern Churches easy developed assorted church acts names Holy Eucharists from topographic points such as Antioch, Alexandria, and Epheus. As Dimitri Comonos references in the cyberspace article for Byzantine music , these topographic points used the single-channel vocal music at the clip. It is besides rather important to advert that Byzantine music had a immense consequence on the Western chant. Byzantine music was the predominate music for a really long clip which besides lasted for more than 13 centuries. Byzantine hymnography was so split into two periods which gave a new rhythmical form to hymnography. During the first period, dated from the fifth century, the kontakion was developed. In the 2nd period, dated from the terminal of the seventh century the chief anthem developed during the period was the kanon . Egon Wellesz, in his book A history of Byzantine Music and hymnography , references that: Byzantine hymnography is the poetical look of Orthodox divinity, translated, through music, to the domain of spiritual emotion. It mirrors the development of the dogmatic thoughts and philosophies of the Orthodox Church from the early yearss of the Eastern Empire to the full luster of the service at the tallness of its development. The anthem is one of the most of import genres which was developed in Byzantine music. There are assorted sorts of anthems such as the troparia , kontakia and kanones . In an inernet article of Byzantine music Dimitri E. Conomos references that: During the first nine centuries of Christianity, the Byzantine musical tradition of plainsong managed to maintain alive a certain improvisatory excitement that was besides manifest in the spontaneousness of supplications and rites in the early Christian Holy Eucharist. Now, with some shots of a 9th-century pen, the plainchant tunes were caught in a stiff stylization. They became as if embalmed and their stylistic profiles conformed to 9th-century and finally, subsequently, gustatory sensations. The old chants that originated as sung supplications were henceforth crystallised art-objects. Troparia are short responses between the Psalms. The first troparia were written in the fourth century. The tune type of troparia bit by bit became quite important and easy some of troparia developed into more independent anthem. Harmonizing to the cyberspace article, Orama World there is a possibility, that the earliest sets of troparia were those of the known writing of monastic Auxentios which dated from the 5th century. Two of the most of import illustrations of troparia are the Phos Hilarion , which means Gladsome Light , and is dated from the fourth century and O Monogenis Yios , which means the merely Begotten Son . These two illustrations can be found in the introductory portion of the Thia Litourgia which is the Divine Liturgy . The Troparia terminal with two words mentioning to God and are repeated many clip. The features of these anthems are the stichera and the kanones. The stichera are sung in between the poetries of the Psalms. Sticheron is one of the most important parts of Byzantine anthem and the complete music of the stichera is the Sticherarion. The development of the kontakion began during the fifth century A.D. It is a long and complicated metrical discourse. Kontakia evolved from 13 into 18, and in some instances into more than that, with stanzas which are all structurally similar. Accoridng to an cyberspace article in the Britannica Online Encyclopedia, kontakion was introduced into the Byzantine spiritual pattern by St. Romanos Melodos during the first half of the sixth century. St. Romanos became one of the greatest early Christian poets. Harmonizing to the writer of an article in the Goarch it is stated that the first notated versions of kontakia were melismatic which means that there were many notes per syllable and they appeared during the ninth century. Kanones, and their tunes contain texts which were hodgepodges of stereotypic phrases. The tunes were developed harmonizing to the rule of centonization which was qiote common in Eastern music at the clip. Alexander Lingas in his article Hesychasm and Psalmody which is found in the book Mount Athos and Byzantine Monasticism , references that the Sticherarion, which is a book incorporating theoretical account tunes for canons and stichera, contains some syllabic tunes which are easy and each 1 has a alone melodious expression. Sticheron is a type of anthem which is used in the Divine Liturgy. In an article which is found in Grove Music Online , Kenneth Levy and Christian Troelsgard reference that kanones are hymnodic composites which are comprised of nine odes. Each ode includes the heirmos which is followed by troparia with the same music and metrical reproductions as the heirmos. The nine odes are normally independent. A kanon consists of nine different and independent tunes. As Grigorios Stathis references in I- I’I†¦I ¶I ±I?I„I?I?I ® I?I?I†¦I?I?I?I ® I?I„I · I »I ±I„I?I µI?I ± I?I ±I? I?I„I ·I? IIˆI?I?I„I ®I?I · , ( Byzantine music in faith and scientific discipline ) , psalmodia is another basic feature of the Christian Orthodox people. The Byzantine music is music which is wholly written for the church and it is used in the Christian Orthodox Churches in to pray to God, the Son and the Virgin Mary. Alexander Lingas in Hesycasm and Psalmody , says that during the 14th century the hymnody used in the Byzantium had a scope of signifiers and was thought to be a really important cloistered plus which held the chance of being infused with the idea and this shows that the hymnody was accomplished with the head and bosom on God. Psalmodia is sung by the psaltes who are trained in order to sing church music. Psalmodia is the lone chant of the Greek Orthodox Church. Christians who were Grecian speech production used the term psalmodia in order to picture the signifiers of the liturgical vocalizing. Psalmodia which was used in Constantinople had a important map in the agreement of the different Rite of the Church of Hagia Sofia. Alexander Lingas in Music and Liturgy of the Orthodox Traditions references that: All public services of the Byzantine rite are sung, there being no equivalent in the churches of the Orthodox East to the Low Mass of the Latin West. While the proper ecclesiastical term for liturgical vocalizing remains psalmodia, the repertories of plainsong that developed in tandem with the services of the Byzantine rite are today frequently referred to as Byzantine chant or Byzantine music . Chapter four The New Method or Chrysanthine Method Chrysanthos had a good instruction, really good cognition of Latin and Gallic and every bit good as European and Arabic music. He started off as a monastic and so became a hierarch. Peter Byzantios so taught Chrysanthos to intone until Chrysanthos could be considered as a great instrumentalist and composer. Harmonizing to Dimitri E. Comonos article, he mentions that before the foundation of the School, Chrysanthos had used traditional methods of learning which caused his expatriate from the Constantinopolitan Patriarchal to Madytos. However, Chrysanthos did non halt learning the ecclesiastical music because his system for learning was really effectual due to his pupils being able to larn the music notation system of Byzantine music merely in 10 months and non 10 old ages. Subsequently on Holy Synod decides to accept his learning methods and in 1815 he stated learning at the 3rd Patriarchal School along with Protopsaltis Grigorios and the archivist Chourmouzios. In the prologue of I?I µI†°I?I ·I„I?I?I?I? I?I ­I?I ± I„I ·I‚ I?I?I†¦I?I?I?I ®I‚ I?I?I†¦I?I?I?I ®s I §I?I†¦I?I ¬I?I?I?I†¦ I„I?I†¦ I µI? I?I ±I?I?I„I†°I? ( Theoritikon Mega Ti MI?usikis Chrysanthou tou ek Maditon ) , Georgios N. Constantinou quotes the words of Dionysius Vatopedinos which were said during the Holy Eucharist in the Patriarchical Music School: IsI ±I„I ±I†¦I„I ¬I‚ [ I„I ±I‚ I ·I?I ­I?I ±I‚ ] I ·I?I?I?I†¡I?I · I µI?

IˆI?I†°I„I?I?I?I?I?I µI »I?I? ( ) , ( 1815 ) . The account of Dionysius Vatopedinos s missive is the followers: In those yearss a new school opened and teaches a new scientific method of music with regulations and grammar. Teachers are the monastic Chrysanthos and the torchbearer of the Great Church, and more than two 100 pupils are go toing it. Among them are priest and bishops ( aˆÂ ¦ ) , ( 1815 ) . Dionysius Vatopedinos fundamentally states that a school was opened in order to learn the new method of Byzantine music notation which included grammar and regulations of music. The chief instructors were Chrysanthos, a monastic, and the torchbearer of the Great Church. Many pupils including monastics, priests and society people had visited the school in order to larn the New Method of Byzantine music notation. David J. Melling references in an article that: Confronting the complex and hard notation they inherited from their mediaeval predecessors, and an emerging spread between the musical texts used by adept psaltai and the traditional liturgical tunes handed down by ear, several instrumentalists attempted to reform the notation to bring forth something simpler and more intuitive. Indeed, there is grounds that there had already emerged ways of composing a rapid short-hand version of the marks which could even be used to observe down a tune as it was being Sung. A peculiarly successful simplification was designed by Peter Lampadarios [ +1777 ] , but this was eclipsed by the great Reform of the Three Teachers, Houmouzios, Grigorios and Chrysanthos, who designed a new, more analytic notation and transcribed into it a prodigious figure of texts from the psaltic repertory. The New Method of Byzantine Music notation was created during the eighteenth century and began to be taught in the nineteenth century. This included rather simple marks against the two old methods of Byzantine music notation. The New Method is besides called the Chrysanthine Method which took its name from the monastic Chrysanthos who subsequently moved on to became one of the reformists of the church s music notation in 1815. The other reformists of the Byzantine New notation system were Chourmouzios the archivist and Gregorios the Protopsaltis, who was lampadarios ( torchbearer ) . The New Method is still used even today. In The manners and Tuning in Neo-Byzantine Chant Frank Harry Desby references that: Before the New system, ten old ages were required to larn music. The new method made it possible to larn in 10 months. Kate Romanou besides mentions in her article A New Approach to the work of Chrysanthos of Madytos that: The New Method preserved the earlier differentiation between the quantitative and the qualitative neumes. The former indicated the existent notes, while the latter, the rhythmic and expressive niceties or decorations which applied to the notes. Apart from the old marks The New Method, includes new marks of which some were phrasing marks, marks for chromatic intervals, remainders and continuance marks. Chrysanthos besides abrogated a few of the old marks and established new ways of notating. Furthermore in an article Dimitri E. Conomos references that: Chrysanthos besides introduced new procedures of transition and chromatic change and abolished some of the notational symbols. As a consequence of these attempts, a big repertory of psalmody was made available to melody pipes who were ignorant of the melodic and dynamic content of the old marks. With those alterations the choirmasters had the chance to sing a batch of anthem which were hard to make with the old notation systems. In an cyberspace article found in The music portal , the author references that there are three basic tones which are used in order to tune the sound. These tones, which are characteristic of the New Method, are the meizon ( major ) , elasson ( minor ) and the elachistos ( minimun ) . It is besides mentioned that each tone is made up from two tetra chords and one major tone. Byzantine music can acknowledge the octave but the sounds are based in tetra chords and pentachords which are groups of four and five notes consequently. Byzantine Psalmodia uses assorted manners and the choirmaster must cognize all the types every bit good as the features of the manners, in order to understand and be able to intone the music. In another cyberspace article found in The music portal , it is stated that this system is made up of eight manners or echoi ( sounds ) which are split into in the chief four sounds and the five manners. Each reverberation ( sound ) has a different intervals every bit good as gradual development. Morover, Chrysanthos besides structured the eight manners into three different types which are the diatonic, chromatic and enharmonic. These types are besides called three Genera. The diatonic genera, is split into three basic types: the meizon ( major ) , elasson ( minor ) and elaxistos ( lower limit ) . The octave of dad, vou, tabun, di, ke, zw, Ni is divided into 72 stairss or tones. The major tone had 12 grades, which means one tone or measure. The minor tone had 10 grades which means one measure and the minimal tone had 8 grades which means half measure. The diatonic graduated table has besides been a ground of an statement which took topographic point between Chourmouzios and Chrysanthos. Harmonizing to an article written by Ioannis Plemenos, Chrysantho s sentiment was that the diatonic scale consist of major and minor tones, one by one, which began with a minimal tone and hence the diatonic graduated table consisted of 64 units. However the the right graduated table for Chrysanthos had to dwell of 68 units. Therefore, Chourmouzios suggest a new version which could finish the graduated table of Chrysanthos and which consisted of 69 units. Finally, Chrysanthos borrowed the 72 unit division from Aristoxenos, who was a good know mathematician and great music theoretician at the clip. Antioxenos had expressed his ain sentiment in concern to the music intervals of the diatonic graduated table which was the 1 that had the highest proportion. In the image below we can see the diatonic graduated table, as they are in the internet article of David J. Melling: F G A Bb C D E F | 12 | 10 | 8 | 12 | 12 | 10 | 8 | Ga Di Ke Zo Ni Pa Vu Ga The diatonic graduated table is divided in three different types which are the diapason, troxos and triphonia. Diapason is non tranferable and Troxos can besides be called as tetraphonia. In The manners and Tuning in Neo-Byzantine Chant Frank Harry Desby states that: The tetachords are all disjunct. In triphonia the tetra chords are conjuct. The diapason assortment was normally found on kanona or pandoura. Pandoura is a twine instrument which includes three brace of strings. In an article found on the Remoundos web page, the writer references that During the Byzantine period, it [ the pandoura ] is appeared to derive some credence among the civilized persons, since the Archbishop Chrysanthos considered that it was necessary for learning Byzantine music. On pandoura there are some rings which are used in order to slpit the musical instrument into assorted parts where the notes are fixed. Harmonizing to Frank Harry Desby in The manners and Tuning in Neo-Byzantine Chant , he states that the tuning of pandoura has intervals for illustration, perfect fourths and fifths, which are ordinary intervals. However it besides includes some assorted sound effects, for illustration the diapason system is the one which is used in most instances. By stating troxos we mean tetraphonia or a rhythm of five notes. The octave between troxos and diapason is rather similar. Finally, the triphonia or tetrachordon as the tetra chords are joint. In his book, The manners and Tuning in Neo-Byzantine Chant , Frank Harry Desby states that it consists of four confused tetrachords or joint fifths. In this graduated table nevertheless there is no meizon ( major ) tone. In another article, David J. Melling besides mentions that: Here we have big tones of 12 steplets, indistinguishable in size with the Enharmonic tones, but accompanied by lesser tones of 10 steplets and big half steps of 8 steplets. The chromatic graduated table is divided in two types. These are the difficult chromatic graduated table and the soft chromatic graduated table. Below we can see the two types of chromatic graduated tables: Hard chromatic graduated table: D Eb F # G A Bb C # D | 6 | 20 | 4 | 12 | 6 | 20 | 4 | Pa Vu Ga Di Ke Zo Ni Pa Soft chromatic graduated table: C Db E F G Ab B C | 8 | 14 | 8 | 12 | 8 | 14 | 8 | Ni Pa Vu Ga Di Ke Zo Ni The enharmonic graduated table consists merely of 12 and 6 grades: F G A Bb C D E F | 12 | 12 | 6 | 12 | 12 | 12 | 6 | Ga Di Ke Zo Ni Pa Vu Ga Pa Calciferol Rhenium Vou Tocopherol Myocardial infarction Tabun F Fa Di Gram Sol Ke A La Zo Bacillus Silicon Nickel C Nto Chrysanthos made usage of the first seven letters derived from the Greek alphabet which is based on the European system. The graduated table includes the undermentioned syllables: dad, vou, tabun, di, ke, zo, ni. The notes of these syllables are shown in the tabular array below. The chief marks of the Chrysanthine method are ten and their names are: ison, oligon, petasti, kentimata, kentima, hypsele, apostrophos, hyporroi, elafron and chamele. These marks show whether the voice goes down or up or remain the same. These marks are the intermission marks and are besides called neumes. Below the marks and their accounts can be seen, as taken from an on article of St. Anthony s Monastery written by monk Ephraim: ison Chapter V Advantages and disadvantages, of the new method. The Byzantine music first notation was non really good structured, as there were adequate jobs. The most of the anthem were hard to intone from the choirmasters, as they could non transcribed them. The Paleo-Byzantine Music was excessively complicated, but besides non effectual, as a consequence to be difficult for people to understand it and intone the anthem. Kate Romanou, in A New Approach to the work of Chrysanthos of Madytos references that: If, in malice of the great demand of a simpler musical system, all old efforts to accomplish a reform had failed, it was because they adhered to one of two extremely contradictory attacks: the first which wholly broke with tradition, and the 2nd which displayed the familiar complexness and deficiency of lucidity. The 600 old ages of Middle-Byzantine Music notation usage, show that this notation was better than the first 1. Middle-Byzantine notation system was a complete system but included excessively many complex marks. As I mentioned earlier the New Method of the Byzantine Music notation or else the Chrysanthine notation was and still is the simplest notation system for the Byzantine music. Against the Paleo-Byzantine music notation system, the new system and its marks helped the melody pipes to understand the manner that the anthem must be chanted. Despite the jobs that the Middle Byzantine Music notation faced, it existed for many centuries. The Chrysanthine method was that one which exists since the decennary of 1800 until presents. The marks that Chrysanthos adds to his method describe really clearly how the notes and by and large the tune must be chant. In an cyberspace article, the writer references that: Byzantine notation can be used as a rapid stenographic transcriptional method to compose down a tune faster than one could make so utilizing Western notation. This is peculiarly helpful when seeking to enter unrecorded music on paper. Although there are at least a 100 marks in the Byzantine notation, it is preferred for most of the people. It is non difficult for people to larn the Byzantine music notation, it takes merely a small clip. The marks that Chrysanthos added to the new notation system were really helpful. Traveling to the dissadvantages of the New method of Byzantine music notation, I would wish to advert that despite the disagvantages, no 1 believed that the new method should be changed for a new one. Of class there were some suggestions for altering the system but they declined. The first trouble to the Byzantine notation of Chrysanthos was that the Byzantine music of Constantinople did non accept the tetrafonia. During 1878, as I found in an cyberspace article, some people tried to convert the Grecian society of Constantinople to compose the Byzantine anthem utilizing the European system notation. Finally, this was neer happened. During the clip that Chrysanthos introduced the New Method, there were some reactions against the new system. In an cyberspace article and harmonizing to proffesor Ioannis Plemenos, there were many expostulations from the people and espacially for Vasileios Stephanides, a musician and physician during 1819. Vasileios Stephanides believed that Chrysanthos s determination non to utilize some of the marks of the old notation systmes was incorrect. In 1820, as Ioannis Plemenos references in his article, Apostolos Konsta was besides did non accept the New Method of Chrysanthos. Ioannis Plemenos places the words of Apostolos Konsta, which are the undermentioned: ( ) I ­I?I ±I?I µ I?I ±I? I ±I†¦I„I? I?I†¡I?I »I µI?I?I? I?I?I?I?I? I„I†°I? I† I?I?I?I?I†°I? , I?I„I ¬I?I µI†°I? I?I ±I? I†¡I µI?I?I?I?I?I?I?I ±I‚ I?I?I ± I?I ­I?I?I†¦ I„I ·I‚ I?I†¦I?I?I ·I„I?I?I ®I‚ , I ­I†¡I ±I?I µ I?I?I†°I‚ , I ±I »I »I?I?I?I?I?I?I? , I„I ·I? I ±I?I?I µI »I?I?I ®I? I?I µI »I†°I?I?I ±I? , I„I ± I?I?I„IZ I?I ­I?I · I„I ·I‚ I?I »I†¦I?I†¦I„I ¬I„I ·I‚ I µIˆI?I?I„I ®I?I ·I‚ . This means: The three instructors opened a school, merely for notes, remainders and Heironomia, but they lost the b eatific tune and the eight parts of the sweet scientific discipline . Apostolos Konsta means that the new school which opened to learn the New Method of Chrysanthos, was learning merely some notes and marks and lost the chief topic which was the beautiful tune. Another job as Ioannis Plemenos references in his article, it was that Georgios the Lesbios, believed that the New system was non good structured because the three instructors did non seek to happen new marks to increase the notes in a specific pitch. Those who were supported the old notation systems did non desire Chrysanthos to learn the New Method, but eventually allow him to learn, although they were opposite. Chrysanthos was learning in the Third Patriarchical Music School. Consequences and results The Greeks owe the musical notation used today in their churches to Chrysanthos of Madytos, Gregory the Protopsaltes and Chourmouzios the Chartophylax. This notational system, known today as the New Method. With the scrutiny of the old notations we conclude that the extant information about the development of Byzantine notation from the autumn of Constantinople to the 19thA century vividly illustrates the fact that Grecian church instrumentalists had become progressively more baffled and puzzled by the old system. At the same clip Byzantine anthem were being sung more and more from unwritten tradition despite the fact that a series of efforts had been made to simplify the bing notation. Byzantine music is the most of import facet of the Orthodox Christian Church. In our yearss the Orthodox Christian Church is still utilizing the New notation system for their chants and anthem. What is the ground of making that? The ground is that Byzantine notation system is the lone manner to notate the anthem and chants, as the melodious lines includes tonss of melismas but besides hard and unusual types of harmoniousness. Another ground is that, Church wants to forestall its tradition and a manner of making that is maintain that notation system. With analyzing the Byzantine music we can see that Christians use the voice entirely in executing of anthem, intoning as did our Godhead Himself and His adherents. St. John Chrysostom says: Our Savior chanted anthem merely as we do. The Apostolic Constitutions forbid the usage of musical instruments in the church. From the clip of the Apostles, hymnody was single-channel, or homophonic, as it is to this twenty-four hours in our churches [ in Greece ] . The Western Church, in order to satisfy people and blandish their gustatory sensations, put instruments inside the churches, disobeying what was ordained by the Fathers. They did this because they had no thought what liturgical music was and what secular music was, merely as they did non cognize the difference between liturgical picture and secular picture. But the Byzantines distinguished the one from the other, and this shows how much more religious they were in comparing with the Westerners and how much more genuinely they experienced the spirit of Christianity. Byzantine music is, in comparing with the music of the West, precisely as Orthodox iconography is in comparing with the spiritual picture of the West.

By reading this guide, you will be able to outline and seamlessly write a stellar essay. Without further ado, here are 10 facts on the spatial order in human visual perception: The human visual perception is far beyond our imagination. When we see our Earth’s surface, it appears that we can see nothing more than a few kilometers that lead up to the horizon. This is because the surface of the Earth literally curves out of sight after 5 kilometers.If the Earth’s surface were to be flat on the other hand, you would see a flickering candle flame even 48 kilometers away. In addition, our naked eye can see the Andromeda galaxy, which is located 2.6 million light-years away from Earth. The source of light that enters our retina travels from 1 trillion stars in the galaxy. Technically, we can see the color red with our naked eye, but in theory, it’s quite the opposite. Some scientists believe that the retina has receptors similar to that of an RGB (red, green, blue color spectrum) monitor. However, the eye’s retina can’t detect red shades. The so-called â€Å"red† receptor actually detects yellow-green hues whereas the â€Å"green† receptor detects blue-green colors or hues. These colors are then differentiated by our brain which tells us to see red colors. Selig Hecht, known for his remarkable work on human eye perception, made an accurate measurement of the human vision’s absolute threshold in 1941; i.e. the number of photons that must strike our retinas in order to stimulate the brain with visual awareness.The study that led to such a remarkable discovery was performed under ideal conditions where participants were allowed to adapt to total darkness; flashlights of 510 nanometer blue-green wavelength, acted as a stimulus, to which the human eye is most sensitive. It was concluded that our brain interprets vision when the retina is exposed to 5 14 photons. The human eye perception is limited to a certain degree. We are only able to see colors between 350 to 700 nanometer wavelengths. This is why we are not able to perceive ultraviolet and infrared colors. Ultraviolet colors fall in shorter wavelengths than 350 nanometers, whereas infrared colors are longer than 700 nanometer wavelengths. For example, when you take a look at bananas, you see the color yellow because they bounce off color wavelengths of 570-580 nanometers, when hit by full spectrum light. Have you ever asked yourself why you see things in 3D? Our brain is responsible for reconstructing images which let us experience life from a 3D perspective. This is because we have a pair of eyes that gives birth to a phenomenon known as Binocular Disparity – a slight difference in perspective between the left and right eye. Binocular disparity plays a vital role in giving depth to a scene. Convergence is another phenomenon which signals the brain to create depth of field, particularly when you are focusing on something close to your eyes. While we can see and perceive colors at the center in high resolution, our peripheral vision is very low in resolution – it’s blurry and nearly monochrome. However, we don’t actually see our peripheral vision as a monochrome image because our eyes and brain are quick enough to fill in the required details as soon as we become aware of this fact. It takes time for the human eye to perceive visual depth of a scene. The brain of a newborn child is not fully developed and must adapt to the new environment first before learning to construct a three- dimensional perspective. A study on infants has revealed that it takes a two months old baby to construct depth awareness of an image. Human visual perception is able to â€Å"adjust† to the dark by activating its own ‘night vision mode’. The neural pathways of the brain recalibrate themselves chemically to turn on scotopic vision circuits. These circuits are normally off during the daytime and require 20 minutes of darkness to be active. Scotopic vision circuits do not adapt to colors other than blue, as their receptors are blue-sensitive. You might have noticed how everything tends to take a bluish hue when you are trying to see in the dark. Ever thought why you can see the stars twinkling and shining at night? It’s because these receptors are very sensitive to even minor fluctuations in light. The brain is the main asset behind our visual perception. The eyes are merely tools to perceive light and transfer it to receptors that signal the brain to form images. The brain is, for a fact, the main component that constructs images and enables us to see perfectly. For example, our retina captures and interprets everything upside down, but still, we see everything the right side up. There are 100 million photoreceptors in each eye that enable us to see crystal clear images. However, there is only a million nerve fibers that act as a bridge to the eyes and brain. So, technically speaking, the resolution of our eye is not more than 1 megapixel. These facts will help you come up with your own topics and create masterpieces.

Personal Philosophy Essay Example | Topics and Well Written Essays - 750 words - 1

Personal Philosophy - Essay Example Nursing requires that both nurses and nursing educators explore their own values so they can be better placed to appreciate and respect the cultural values and beliefs of the communities and individuals they serve. It is not possible to examine the aspect of scholarship in nursing education in isolation from the scholar within the â€Å"scholarship†, this comprises of individuals who embody several traits among which are; intense intellectual curiosity, disenchantment with prevailing systems as well as persistence for scholarly growth. In case these ideas were to be inculcated into the scholarship in a school of nursing, they would significantly contribute to the education of nurses who are not only professionally competent but also capable of dealing with situations beyond their call of duty should circumstances a rise. As aforementioned, my core principles are; do no harm and provide the best possible care; these can be implemented in nursing scholarship to mound the trainee s into moral and ethical professionals (Silva and Ludwick, 2005). When nurses are educated in and environment that allows them to express their curiosity, they will acquire more knowledge through in-depth research and studies which will ultimately make them better placed to deal with patients from their wealth of both theoretical and practical knowledge. Furthermore, when they are disenchanted with the prevailing systems, it means they will desire to improve them by examining alternatives and this will boost creativity. The second aspect of my personal philosophy has to do with elimination of discrimination, while this has been covered in nursing training; the elements of prejudice are still evident in nursing practice. This is however not exclusively emanating from nurses but possibly from patients as well, for instance a patient may express discriminatory, for instance racial bias to the attending nurse. In case, the nurse is not objective in his/her practice of care, they may dev elop a negative attitude towards the patient due to the offence and this may be reflected in the quality of care. In my opinion, the best way to bring about changes in the scholarship of nursing through scholarship is to teach it both as a science and art, such that it creates and avenue for excellence through which teachers supply technical knowledge, wisdom and humanity to students (Silva 2012). After the examination of prevailing conditions changes can be implemented through Lewis model of change that requires, the unfreezing of previously held perception, then the scholars can move on to other ideas which if found to be progressive can be refrozen until such a time they will require to be changed of improved (Mitchell 2013). In addition, this also results in inspiring students to think critically and reflectively so that they question convectional practices and strive to be better citizens of the nursing and global community. While ethics may be theoretically taught in class, un til a student is inspired to examine the process of nursing for him/her and make their own conclusions, they will only see them as abstract concepts. For effective change in the field of nursing scholarship; so that it may produce the best caliber of nurses, it is

Business Law Assignment - Coursework Example The paper tells that in the Constitution of the United States, Article 1, Section 2 refers to the qualifications that must be met to serve as a member of the House of Representatives. It states that â€Å"No Person shall be a Representative who shall not have attained to the Age of twenty five Years, and been seven Years a Citizen of the United States, and who shall not, when elected, be an Inhabitant of that State in which he shall be chosen†. Article 1, Section 3 of the Constitution delineates the requirements to become a Senator, by stating that â€Å"No Person shall be a Senator who shall not have attained to the Age of thirty Years, and been nine Years a Citizen of the United States, and who shall not, when elected, be an Inhabitant of that State for which he shall be chosen†. The qualifications to serve as President of the United States are found in Article 2, Section one. The document states that â€Å"no Person except a natural born Citizen, or a Citizen of the United States, at the time of the Adoption of this Constitution, shall be eligible to the Office of President; neither shall any Person be eligible to that Office who shall not have attained to the Age of thirty five Years, and been fourteen Years a Resident within the United Statesâ€Å". The Age requirement for the House of Representatives is five years less than the requirements for senate and ten years less than for president. The age and citizenship requirements for Senate exceed those of the House by five and three years respectively. They are less than those for President by five years for both categories. The qualifications to serve as President are the highest exceeding the age requirement for the House by ten years and the Senate by five years, and the citizenship requirement for the House by seven years and for Senate by five years. All three of the offices require that the Person be a natural born Citizen of the United States. Question 2: Stanglin argues that the ordin ance violates the equal protection, because there is no rational basis to suppose that children are at a greater danger being near a class E dance hall than a skating rink. I disagree with this statement. The Equal Protection clause states that "no state shall ... deny to any person within its jurisdiction the equal protection of the laws† (US Const., amend. XIV). This statement taken on its own can be taken either extremely strictly or be loosely interpreted, but there is a rather extensive history of supreme court cases that has led up to the current guidelines on interpreting this clause. Some of the most famous of these cases had to do with equality between races, women’s suffrage and the rights of immigrants. Currently the equal protection clause is interpreting as protecting state governments from discriminating against these types of rights--fundamental or inalienable rights. For cases like Stanglin’s, where no fundamental rights are involved, the state ne ed only to show there is some type of rational basis for whatever distinction they make through the law. Since the state passed the ordinance in the interest of protecting the youth from drugs and dangerous sex, it was not passed arbitrarily and thus not irrational. Personally, it seems to me that Stanglin filed this suit simply out of personal interest, because he would lose money for his business. I don’t think the equal protection should ever work in this way. The clause is not to be used for protecting the profit seeking interests of business from regulations imposed by local governments. It is to protect people from arbitrary and unjust discrimination of the law. Question 3: The primary element in this case, is the fact that Hernandez relied upon a promise that a business made to him, which they failed to keep causing him to suffer monetary loss. Thus I am certain Hernandez should win this case given that the circumstances meet the criteria for promissory estoppel. The t ext defines a promise in a promissory estopp

Watergate Scandal Essay Example | Topics and Well Written Essays - 750 words

Watergate Scandal - Essay Example Edward M. Kennedy and a young woman’s death. Remarkable of this incident is that it engulfed the U.S President Richard M. Nixon and many of his followers in an array range of illegal acts and hence triggered the resignation of the president who ended as â€Å"one of the sorriest spectacles in [U.S] national experience,†1 as a journalist from the New York Times put it. According to many investigations, the burglary has been carried out by five men who were later captured in the Democratic National Committee Watergate hotel. This serious incident garnered little media attention, yet it should be pointed out that two dedicated reporters, Bob Woodward and Carl Bernstein, both of whom were working for the Washington Post played, particularly, critical roles and managed somehow to uncover the president’s sponsored plan of espionage to discredit Democratic candidates. In addition to the reporters, another man called Sussman was directly involved in the Post’s effort to reveal and unveil the truth in the face of the general apathy by the press and the public and the White House pressures. Sussman cleverly remarked that the mass media, namely the press, was just not much concerned with the Watergate issue at the very beginning; however, the Post did its best and utmost to unearth the scandal. Sussman added that even the Congress repeatedly attempted to avoid if not ignore the Watergate Issue. He wrote that an â€Å"overwhelming number of congressmen had consistently turned their backs on Watergate until it surrounded them. They were still reluctant to deal with it, hoping Nixon would solve what was becoming their dilemma.†2 No doubt the Watergate scandal aroused considerable interest in how scandals are covered and oftentimes uncovered by the mass media. Of course, none can deny that the whys and the wherefores of Watergate have been widely investigated as many scholars conducted serious investigations and surveys about it. We can mention, in this

The current status of immigration, proposed changes to immigration Research Paper

The current status of immigration, proposed changes to immigration policy, and what all of this means for HR - Research Paper Example An analysis of current and required legal immigration policies is being discussed with the implication to Human Resources. An Overview of Immigration Laws: Federal immigration law of United States establishes if any person is eligible to gain residence or citizenship within the country. The law provides a means through which certain individuals may become legally naturalized citizens with all rights of citizenships. It is the responsibility of Federal government to determine the immigration policies by controlling visa processes. There are two types of visas: â€Å"immigrant visas† and â€Å"non immigrant visas†. Primarily the visitors or tourists are issued non-immigrant visas. However, the holders of immigrant visas may be permitted to stay in the United States by fulfilling few legal requirements (Walsh, 2013). Legal requirement for Immigrants: United States, policy makers are providing immigration support to its current and other Foreign Nationals as per their immig ration policies underlining the areas of Human Resource so they can make a significant contribution in the workforce of any organization. There are legal terms, which are used for individuals who are migrating to the United States depending on their visa status and immigration status: Foreign National: is a term used for members who are not citizens of United States. They can be Lawful Permanent Resident (â€Å"green card† holder), Refugee or Temporary Resident as per1986 amnesty program when they were appointed by any organization. Nonimmigrant Visa Status: is a temporary immigration position, which provides permission for a Foreign National to work or study at any University. It includes H-1B status, TN status, and O-1 status. Immigrant Status, Permanent Residence or â€Å"green card†:  is the term given to a status, in which individuals have the right to live, work or study in the United States. A close family member or an employer may sponsor these persons to bec ome permanent residents (Walsh, 2013). Confirmation of Employment Authorization   As per the policies it is required by the federal law that all employees which are hired after November 6, 1986, without prejudice, whether the person is U.S. or foreign-national, has to sign United States Citizenship and Immigration Service Form I-9, the Employment Eligibility Verification.  Employees must complete Section 1 of Form I-9 and give all original  documents or documents as required so that their identity is established. The Director of Employee and Labor Relations then reviews this copy and the information is recorded (Walsh, 2013). Employment of Foreign National Workers As per the policies for Foreign National workers, employees will not be allowed to work for any organization until approved by federal law.   The organization’s Human Resource Department will determine if the Foreign National is authorized to begin employment. In order to be employed by the University, the w orker must have a Nonimmigrant Visa or Employment Authorization Document, which is not expired (Walsh, 2013). Immigration Sponsorship does not affect or replace Employment Policies There may be any employer’s conformity or willingness to sponsor any foreign worker for legal permanent residence. It may not be a contract of employment and may not supersede any of the employer’

Human services legislation Essay Example | Topics and Well Written Essays - 500 words

Human services legislation - Essay Example overty level was increasing at a rapid rate, which made the Johnson administration to come up with a program that would be run by the government to try and reduce the poverty level. The legislation worked out well because the poverty level was greatly reduced over time to a lower level. Expounding on the war on poverty will paint a clear picture on the impact and benefits of the legislation. The war on poverty is a legislation that was pioneered by United States president Johnson Lyndon in a state address. Johnson proposed the legislation in response to the rising poverty rates. The proposal allowed the United States congress to pass the economic opportunity act which then instituted the office of economic opportunity to oversee the local application of funds aimed against poverty. Johnson believed in increasing the government’s roles in reducing poverty and bettering education and health care as strategies of reducing the poverty rates. Johnson had an aim of not to cure the symptoms of poverty, but to cure it and above all, to prevent it. During Johnson’s administration hearing before the select committee on poverty of the committee on labor and public welfare, President Johnson decided that the United States was not going to put up with the increasing poverty rates anymore (Zarefsky, 1986). The notion was that prosperity alone was not going to get rid of the increasing poverty rates. Johnson emphasized that the war on poverty would create job opportunities, and also lead to planning and organization of resources, to break the cycle of poverty in communities. The main social problems were poor education and health care, lack of job opportunities, poor transportation and urban problems. According to Phelps, this is why President Johnson found it more convenient to curb those social problems in order to fight poverty in a more orderly manner (2014). This is especially because poverty is related to issues such as lack of education, jobs, proper healthcare

Solar Radio Emissions: Investigating Reactivated Prominences

Solar Radio Emissions: Investigating Reactivated Prominences Madeleine Eve Andrew Johnston Solar Radio Emissions in Investigating Reactivated Prominences Literature Review Abstract Astronomical objects that have a changing magnetic field can produce radio waves, which are the longest waves in the electromagnetic spectrum. By studying the radio waves emitted by the Sun, astronomers can acquire information about its composition, structure and motion. This aim of the present project is to use solar radio emissions produced during the re-activation of prominences in order to investigate possible energy sources for the activation. The purpose of this literature review is to analyse relevant papers on the subject matter that will be covered in this project, and give a summary of the literature in the field, whilst covering the history and importance of the topic, along with what types of instruments can be used to measure radio waves, and how radio waves are useful in studying prominences and their reactivation. 1 Introduction Radio waves are a type of electromagnetic radiation, which is a form of energy produced whenever charged particles are accelerated. They have frequencies from 3kHz to 300GHz, with corresponding wavelengths ranging from just 1mm to 100km. The understanding of solar radio emissions began in 1942, when an English physicist and radio astronomer, James Hey, was tasked to work on radar anti-jamming methods for the military. He had several reports of severe noise jamming of radars signals in the 4-8 meter wavelength range, and after examination, he realised that the direction of maximum interference was coming from the Sun, and concluded that the Sun radiates radio waves (M. Pick, 2008). The observation of solar radio emissions has proved to be a useful tool in our efforts to understand solar physics., In particular solar radio emissions can be used to study local plasma density and magnetic reconnection, which relates to the release, over periods of a few minutes, of magnetic energy stored in the corona and which accompany solar eruption events like prominences which this project will be focusing on. In addition, radio wave emissions from solar flares offer several unique diagnostic tools which can be used to investigate energy release (A. O. Benz; 2005), plasma heating, particle acceleration, and particle transport in magnetized plasmas. A Solar flare is an observed sudden flash of brightness over the Sun’s surface or the solar limb, powered by magnetic reconnection. Scientists study the Sun through radio emissions and other electromagnetic emissions and this has an additional advantage in that it provides a better understanding other stars, and the important processes they have to offer, such as nuclear fusion, which is a potential alternative energy source scientists have been trying to recreate on Earth for decades. The study of prominences and other eruptive events is important for providing an insight into the mechanics of the interior of the Sun, and also to assist us in the prediction of ‘space weather,’ which can effect satellites, and the Earth’s atmosphere and magnetic field. A solar prominence is a large, bright, gaseous feature that is anchored to the surface of the Sun in the photosphere, and extends outwards into the Sun’s corona in a loop shape. Solar prominences are made from plasma that is roughly 100 times cooler and denser than the plasma in the corona and so, when viewed with the sun as a backdrop, they appear dark, and are referred to as ‘filaments.’ They can last for several months, and are held in place above the Suns surface by strong magnetic fields. The exact composition of prominences is currently unknown, but it has been proposed that they are made up of roughly 10% helium and 90% hydrogen. Solar prominences, like other erupting projectiles, are useful to observe as they are good indicators of the magnetic field pattern of the sun, since they lie above the magnetic neutral lines. There are two basic types of prominences: quiescent and active-region prominences. Quiescent prominences are typically larger than active-region prominences, and also extend further into the corona, often reaching up to and over 30 000 kilometres above the Sun’s corona (T. E. Berger, 2012). In addition, quiescent prominences have a magnetic field of roughly 0.5-1mT, allowing them to extend further from the surface of the Sun than active-region prominences, which are much smaller, have much larger magnetic fields of around 2 – 20mT, and mostly do not travel over 30 000km. This project will largely be focusing on Quiescent prominences, as, extending further away from the Sun, they are easier to study using radio waves. Prominences are always projected from filament channels, which are along polarity inversion lines; where the magnetic field is highly non-potential (J. Chaf, 2005). These channels are the source of all major solar eruptions, such as coronal mass ejections and flares. The temperature of a prominence that hasn’t erupted, is typically , and these often appear as a long horizontal sheet of plasma. Several different models have been proposed in order to explain how cool, dense objects like prominences can be supported and thermally isolated from the surrounding hot coronal plasma. It is generally accepted that these models can generally be placed into one of two main categories: dip models, and flux rope models (for example: D. H. Mackay, 2010, D. J. Schmit, 2013, P. F. Chen; 2008). The main similarity between dip models and flux rope models is the suggested existence of concave-upward directed magnetic fields to support the prominence plasma against the downward gravitational force. Following this mechanism, it can be assumed that the plasma in a prominence is frozen to the magnetic field lines. Prominence plasma, however, is actually only partially ionised, and so it is not entirely clear how the non-ionized portion of plasma is supported, and how rapidly the neutral material might drain across the magnetic field lines. Scientists are still researching how and why prominences are formed, and the cause for their reactivation. The models proposing how prominences are supported are vital in understanding their formation and reactivation. 2 Radio Emissions with Prominences Measurable coherent radio emissions occur during flares, and are intermittent and in bursts, driven by the magnetic reconnection process, giving them the term ‘radio burst.’ Previous experiments (J. P. Raulin; 2005, J. P. wild; 1956, R. F. Wilson; 1989, G. Swarup; 1959) in measuring radio emissions produced from prominences have found that Type I bursts are predominantly emitted, Type I being characterised by their long lifespan lasting from hours to days, having a frequency of 80-200mHz with corresponding wavelengths of roughly 2m, and being produced by electrons with a charge of several keV within coronal loops. Moving Type IV radio bursts are also associated with prominence eruptions, these last from half an hour to 2 hours, with a frequency of 20-400MHz, and a corresponding wavelength range of 1 to several meters. As mentioned in the introduction, scientists can use radio waves to gain an insight into how plasmas behave during the prominence eruption process. This can be done through magnetohydrodynamics (MHD), which is the study of the dynamics of electrically conducting fluids. Scientists have previously used MHD equations in investigations to understand the formation and reactivation of prominences (J. A. Linker; 2001, D.J. Schmit;2013, G. P. Zhou;2006, A. K. Srivastava; 2013). An investigation using SDO/AIA (T. E. Berger; 2012) on the formation of prominences produced a series of images that showed the reactivation of a prominence. The sequence showed that after a prominence has completed its eruptive cycle, it slowly disappears due to drainage and the lateral transport of plasma, and a bright emission cloud forms in the upper regions of the coronal cavity. The cloud descends towards the lower region of the cavity while successively becoming brighter, and a new prominence then forms, rapidly growing in both the vertical and horizontal dimensions. The new prominence is the reactivated old prominence. The coronal cavity core in the image then grows darker as the reactivated prominence continues to grow. The reactivated prominence reaches its maximum size after a number of hours, and the emission cloud in the cavity reduces correspondingly. Using the time sequence of images from this T. E. Bergers paper, an idea of what to search for in data to find reactivat ed prominences can be formed. Work has been performed (by C. Chifor; 2006; D. H. Mackay; 2010, D. J. Schmit, 2013) which also investigates how prominences are formed, concluding that reconnection events trigger different phases in prominence eruption. The flux rope model discussed earlier has been found to be a good model in several investigations (S. E. Gibson; 2006, P. F. Chen; 2008, G. P. Zhou, 2006). Helical field lines provide a support for the mass of the prominence, and are capable of storing the magnetic energy needed to propel the prominence. A coronal flux rope can be interpreted as a magnetic structure which consists of field lines that intricately twist around each other a number of times between the two ends that are anchored to the photosphere. Studies mentioned earlier involving MHD have been found to support the flux rope model, making the model a good investigation point for the project. Further research has been carried out into the cause of reactivated prominences (R. F. Wilson; 1989), producing evidence that suggests that as the initial prominence dissipates, a ‘feed-back’ mechanism occurs, during which interactions of the large scale loops trigger burst activity in lower lying loops. 3 Instruments There are two main types of instruments that can be used to observe objects in the radio wave portion of the electromagnetic spectrum, the type selected for use depending on the strength of the signal and the amount of detail needed. The first type of instrument comprises radio telescopes, which are a form of directional radio antenna. As the range of frequencies in the radio wave portion of the electromagnetic spectrum is very large, there are a variety of different antennae that are used in radio telescopes, differing in their size, design and configuration. When measuring wavelengths of 30-3 meters, the radio telescopes use either directional antenna arrays, or large stationary reflectors with moveable focal points. At shorter wavelengths dish style radio telescopes are more largely used. The second type of instrument comprises radio interferometers, which are made up of arrays of telescopes or mirror segments. The main benefit of using a radio interferometer is that the angular resolution is similar to that of a radio telescope with a large aperture, however, radio interferometers do not collect as many photons as radio telescopes, and they cannot detect objects that are too weak. However, an array of telescopes will provide very good resolution as a result of aperture synthesis. Aperture synthesis is an imaging process that mixes signals from the array of telescopes to produce images with an angular resolution equivalent to that of a single instrument with a diameter equal to the overall size of the array of telescopes. This makes it easy to obtain high resolution images of the Sun. SDO/AIA EUV Several different types of data that can be used to review the radio emissions of the Sun in order to extract information on prominences have been researched. The first is SDO/AIA EUV data; SDO being the Solar Dynamics Observatory, which is a NASA mission that has been observing the Sun since 2010. The goal of the SDO is to understand the influence of the sun on the Earth and close space by studying the solar atmosphere over time and space in many wavelengths at the same time. Currently, investigations are focused on how the Suns magnetic field is generated and structured, and how the stored magnetic energy is converted and released into the heliosphere and geospace in the form of solar wind, energetic particles, and variations in solar radiance, which is the measure of the power per unit area on the Earth’s surface. The SDO uses the Atmosphere Imaging Assembley (AIA), an instrument which provides continuous full-observations of the solar chromosphere and corona in seven extreme ultraviolet channels. The AIA is comprised of four telescopes providing individual light feeds to the instrument. The Extreme Ultraviolet Experiment (EUV) is the instrument that measures the Sun’s extreme ultraviolet irradiance, and incorporates physics based models in order to further understand the relationship between EUV variations and magnetic variation changes in the Sun (N. Labrosse, 2011). Fig 1. This image is an example of SDO/AIA data, taken from (T. E. Berger; 2012) from a time sequence which investigates the radio emissions from the Sun leading up to the reactivation of a prominence event. Using the data produced by the two, an image can be created of the Sun that combines physical processes such as prominences, with information on the magnetic field at the time. An example is shown in ‘Fig 1’ above, which shows a reactivated prominence eruption and its corresponding radio emission in the form of a cross-sectional image of the surface of the Sun. Data collected from the AIA has been made public through online databases, providing a ready set of images and films that can be analysed in order to observe prominences and their reactivation for this project. NoRH The second type of data that will be focused on in order to infer radio emissions from the Sun is Nobeyama Radioheliograph data. The Nobeyama Radioheliograph is an array of 84 antennas dedicated for solar observation at the Nobeyama Radio Observatory, located in the Japanese Alps, and was constructed with the purpose of observing the Sun, using non-thermal emissions in particular. The Nobeyama Radioheliograph is a radio interferometer, and the original data comprises sets of correlation values of all the combination of antennas. The antennas correspond to the spatial Fourier components of the brightness distribution of the solar disk. The Nobeyama Radioheliograph is particularly useful in studying prominences (M. Shimojo, 2005), as due to its large daily observation window, combined with the low time resolution of 1 second, and a spatial resolution of roughly 13†, it can produce highly dynamic images. Even though the NoRH is ground based, the consequences of the surrounding weather conditions are minimal compared to that of other ground based observations, and observations can take place even in turbulent unclear weather. NoRH has also developed an automatic detection method, the most important factor in using the instrument to detect prominences, as data will be recorded automatically when there is an eruptive projectile. However, due to the limited time resolution and the field of view, NoRH cannot detect vary fast or very slow eruptive events, simultaneous events, and events where the structure has a weak brightness. Fig 2 This is an image taken by the NoRH (M. Shimojo) which is an example of a prominence eruption, recorded by the automatic limb detection method. The panels are negative images, so the dark region indicates the high temperature. NoRH uses the radio interferometer to create images of the Sun such as in ‘Fig 2,’ which is an example of use of the automatic limb detection method to record images of prominence eruption. Data recorded from the NoRH automatic limb detector has also been made public through online databases, giving a further set of images that can be analysed in order to extract information on prominences and their reactivation. 4 Conclusion The topics covered in the papers that were researched lead to an adequate proposal of how to investigate the reactivation of prominences. Using NoRH and AIA data from SDO, the radio bursts emitted during the collapse and reformation of a prominence, an idea of what causes the reformation can be found. The investigation will centre on the different models, primarily the magnetic flux rope model, and the magnetohydrodynamics behind them that have been proposed for the formation of prominences, and how these models could support the ‘feed-back’ theory. 5 References J.
