Squander Management Practices - Essay Example Be that as it may, they were insufficient to tackle the clean issues of the ever-expanding age. The MSW age rate expanded from 2.7 pounds per individual every day in late twentieth century to around 4.5 pounds per individual every day (United States, 2002). It at that point settled to this sum because of different approaches and techniques for proficient administration systems. The origin of The Solid Waste Disposal Act and later, Environmental Protection Agency were two significant achievements, since they prompted talks and thoughts regarding waste removal which lead to decrease in age and appropriate administration. Source decrease was additionally one of the techniques conveyed by the United States. It intended to structure items that decreased poisonousness upon wastage and included reuse of items and treating the soil of yard trimmings. This incredibly diminished the age of MSW. Another strategy that managed administration of waste and decrease in MSW age is reusing, and the expense demand. Reusing included reusing of plastic and paper †a technique normally utilized and elevated to date and duty demands prompted decrease in removal of waste. Subsequently, these achievements have advanced in making an increasingly sterile, sound United States of

Radiation Exposure Of Women And Children Essay - 1250 Words

Three different independent studies involve ultraviolet exposure to cohorts of women and children. The paper will use the following studies to determine if exposure to ultraviolet radiation is causal of skin cancer. The first cohort study, Cumulative ultraviolet radiation flux in adulthood and risk of incident skin cancers in women (Wu S, Han J, Vleugels RA, et al., 2014), is a prospective study established in 1976 which follows a cohort of 121,700 registered nurses all of which filled out a questionnaire with risks of chronic diseases. The cohort which was named NHS included participants aged 30-55 years of age who resided within 11 different US states and by the conclusion participants resided in every state with a follow-up rate of 96%. Disease was defined as skin cancer and reported as basal cell carcinoma (BCC), squamous cell carcinoma (SCC), and melanoma (Medical records only collected from those with BCC or melanoma). The exposure of UV Flux (estimation of UVB radiation and UV A radiation) was estimated based on location of participants and the annual UV flux data for a participant s respective location. The second cohort study, Sun damage in ultraviolet photographs correlates with phenotypic melanoma risk factors in 12-year-old children (Gamble RG, Asdigian NL, Aalborg J, et al., 2011), is a prospective study from 2011 which follows a cohort of 1,145 children ages 11-12 born from January 1988 to September 1988.

Postcolonial Literature an Example of the Topic Literature Essays by

Postcolonial Literature - Historical, Political and Cultural contexts Generally, ideologies of nation and nationalism together with theories of modernity and postcoloniality are explained through the recordings of history in all their political, economic, cultural, historical, and archeological implications. It is the analyses of these implications that postcolonial scholars find useful in holding empire accountable, if not for anything else, at least for querying history. Romila Thapar in "The Past and the Prejudice" foregrounds the intellectual impetus behind the colonial method of writing history. She begins by saying: Need essay sample on "Postcolonial Literature - Historical, Political and Cultural contexts" topic? We will write a custom essay sample specifically for you Proceed Students Often Tell EssayLab specialists: I'm don't want to write my essay. Because I want to spend time with my friends Essay writer professionals suggest: Get Help In Writing An Essay Buy College Papers Buy Written Essays Online Assignment Help Buy Essays Cheap There is a qualitative change between the traditional writing of history and history as we know it today. The modern writing of history was influenced in its manner of handling the evidence by two factors. One was the intellectual influence of the scientific revolution, which resulted in an emphasis on the systematic uncovering of the past and on checking the authenticity of historical facts. The other was the impact on the motivation of history by the new ideology of nationalism, with stress on the notion of a common language, culture and history of a group. Indeed, historical studies the world over have assumed special significance in proving the background of nationalism. Thapar also acknowledges that the Enlightenment agenda and the European mode of writing the nation in tracing nationalist trajectories were structurally manipulated to fashion the history of the colonized peoples. Going beyond such an overtly fictive telling, the Subaltern Studies Group argues that there is another layer of colonial domination by showing that historiography of newly emergent nations (as in the writing of nation/nationalist struggles) borrows heavily from pejorative, imperial methods to often ignore, even delete subaltern historiography in order to privilege elitist, official versions. In fact, this argument echoes one of Frantz Fanon's most brilliant insights, wherein he excavated and scrutinized the damaged psyche of the colonized people to show how the native mirrors the desires of the colonizer. Recently, in "Absences in History" Aloka Parasher has foregrounded that debate by posing a challenge to scholarship which relies on poststructural vocabulary to decode colonization and re-encode a new historiography. She says that in our new post-modern consciousness we apparently privilege the margins of the past by constructing a new difference of the other "other" which has all the elements of heterogeneity, multivocality, and open-endedness, but the space and item where these margins of the past meet are the center of history... In a study of pre-modern society [colonized nations] then, where history as we understand it today was an alien concept, we privilege a modern notion of history [that of a de-colonized nation] and all that it entails so that it becomes central, and the object of study to remain distant and marginal. Salman Rushdie's Satanic Verses presents a cacophony of voices, most of them "unfamiliar," a polyphonic babble contesting the right to speak. Far from valorizing "verse" and its ideology, The Satanic Verses demonizes it. This text asserts the centrality of the margins, transgressing and interrogating boundaries of genre, class, time, traditions, geography. If Vikram Seth Golden Gate is Barthes' comfortable "text of pleasure," The Satanic Verses is Barthes' "text of bliss": Text of pleasure: the text that contents, fills, grants euphoria; the text that comes from culture and does not break with it, is linked to a comfortable practice of reading. Text of bliss: the text that imposes a state of loss, the text that discomforts (perhaps to the point of a certain boredom), unsettles the reader's historical, cultural, psychological assumptions, the consistency of his tastes, values, memories, brings to a crisis his relation with pleasure. Rushdie's text is indeed discomforting. The loss it imposes is the loss of familiar aesthetic pleasures: truth is neither beauty, nor beauty necessarily truth, and you need to know much, much more than that in this life. Indeed, if we are to trust this novel, truth and beauty and being are all provisional and precarious. It is not surprising, then, that Rushdie's work has become more a historical icon than an aesthetic artifact. As he writes of a character in Midnight's Children, he is "handcuffed to history" (a fine phrase later used by Uma Parameswaran in titling an essay about Rushdie work). When the furor over The Satanic Verses and the Ayatollah's fatwah was at its height, it was commonly said that The Satanic Verses was the most talked-about novel that was never read. The implications of this statement are double: first, that it is primarily a political, not an aesthetic, document; and second, that it is, as some critics stated at the time, unreadable, perhaps even not a "good" book. That is, it does not deliver pleasure in the comfortable and comforting aesthetic codes we know and to which we respond. Indeed, the novel may refuse to allow the kinds of pleasure that The Golden Gate provides. But Verses has embedded within it other semiotic codes of pleasure: the codes of literary realism, as we can see in the multiplicity of detail, as well as in the insistence on history. In addition, many critics have commented on Rushdie's work as embodying magical realism, or as being postmodernist in its metafictionality. Still other critics have demonstrated the literary and linguistic playfulness with which Rushdie entertains, teases, and pleases the reader. My point in bringing up such well-known literary categories as "literary realism," "magical realism," and "postmodernism" is again to ask us to focus on the uses of the aesthetic in the genre of the postcolonial. Rushdie's politics, his particularity of place, ethnicity, race, his evocation of the frightening "Other reader," do not come exclusive of aesthetic technique. Nor is that aesthetic merely a matter of ornamental decoration. Rushdie's text makes enormous claims to the experience and the discourse of the aesthetic, in o rder to claim its power and its moral force for itself. Rushdie's text, no less than Seth's, sets out to give pleasure. But the nature of those pleasures are different. One way of expressing that difference is in Barthes' terms, the comforting text of pleasure and the discomforting text of bliss. But this structure has an in-built hierarchical ranking--pleasure as lesser than bliss--with which I'm uneasy. Another way, perhaps, of expressing the difference of pleasure might lie in the difference between two of the definitions of the aesthetic that I used at the beginning of this paper: pleasure as evoked by formal expression, and the pleasure evoked by the expression of being of a particular social identity. I would reverse the categories of "minor" and "major" as Jameson uses them in his essay. While Seth's novel makes claims to being major by drawing upon the familiar pleasures of the aesthetic, it is, finally, "minor" because, in making an aesthetic claim to pleasure on primarily literary, formal grounds, it reinscribes the traditional separation of art and politics as forever separate. This is a fairly small, exclusive stage for the operation of the aesthetic experience. In some sense, Rushdie's novel, too, could be called "minor," but in a different sense, and a political sense. JanMohamed and Lloyd speak, not of being minor, but of becoming minor, that is of deliberately choosing to ally oneself with the groups of those who are historically disenfranchised, racial and ethnic minorities, women of all races and ethnicities, all the groups characterized by "difference" from the dominant classes: "'Becoming minor' is not a question of essence . . . but a question of position: a subject-position that in the final analysis can be defined only in 'political' terms--that is, in terms of the effects of economic exploitation, political disenfranchisement, social manipulation, and ideological domination on the cultural formation of minority subjects and discourses". To use this definition of "minor" for Rushdie's work is to follow Jameson's separation of the aesthetic and the political, to perceive the formal properties of Rushdie's text as "flaws" that detract from its provision of pleasure, and, finally, to see it as primarily political rather than aesthetic. But Rushdie's work makes forceful claims for its own aesthetic status. Unlike Seth's, it does not make a singular claim to the pleasures of aesthetic form. Rather, it makes plural aesthetic claims: it chooses to "become minor," in JanMohamed and Lloyd's sense, discomforting us with the expression of "minor" identities, with its "political" identity. But it simultaneously assaults us with formal, aesthetic demands on our attention; that is, it insists on its "artistic" identity. In doing so, it refuses to allow us, as readers, to safely separate art from politics, private from public, experience from knowledge, our private selves from the body politic. This gives it a more expansive, more inclusive stage to operate as a verbal artifact, as a piece of literary artifice: both art and politics, both aesthetics and history, both personal and collective. Here, the pistol shots neither replace nor compete with the concert: they are an integral part of the music. In other words, Rushdie Satanic Verses forces us to reformulate Jameson "Freud versus Marx" as "Freud is Marx"--and this may make it a "major" work, after all. Rushdie's work also suggests the ways in which history has perpetually undermined that dream of wholeness, leaving behind a "deep disorder," a legacy of cultural violation and dependency. The fully autonomous identity for which his characters yearn remains impossible; and the mimicry of other peoples and other values becomes inevitable. Rushdie's work stands as a later moment in both the literature and the historical process of decolonization; he takes what Bhabha describes as that "separation from origins and essences" as his starting point. In attempting to define an independent India's "national longing for form," he uses what: he terms a "historically validated eclecticism" to mount an attack on "the confining myth of authenticity" itselfan attack located in the very ground of his work's language. The most important writer that Anglophone South Asia has yet produced, Rushdie remakes English into a new Indian language called "Angrezi," in a move that at once destabilizes the imperial idea of a standard English to which one must conform and challenges the nativist assumption that there's only one "good, right way" to be Indian. For Paul Scott India provided the mausoleum for "the last two great senses of public duty we [British] had as a people . . . the sense of duty that was part and parcel of having an empire"--the duty, once having taken possession of India, to govern it responsibly and well--"and the sense of duty so many of us felt that to get rid of it was the liberal human thing to do." In literary terms the first approximates to Kipling and the second to Forster. Yet the dichotomy between them no longer seems so clear. They disagree as to what ought to be done about imperialism, but the rhetoric through which each writer depicts India is many ways the same. Both, for example, see the Raj as outside history; both are subject to what the historian Francis Hutchins calls "the illusion of permanence" on which the Raj depended. Nevertheless, Scott's distinction between those "two great senses of public duty" remains a good one, and his own achievement in The Raj Quartet ( 1966- 1975) lay in synthesizing the work of his predecessors to show how those duties came inevitably into conflict. From Scott the rhetoric of English India leads to the work of the two major novelists of the Indian diaspora, Rushdie and the Trinidadian Hindu V. S. Naipaul; a brief comparison of their work will provide this chapter's conclusion. Other important novels have of course emerged from England's engagement with empire in other parts of the globe. One thinks especially of Jean Rhys's Wide Sargasso Sea ( 1966), and Timothy Mo's historical novel about the founding of Hong Kong, An Insular Possession ( 1986), not to mention the national literatures of Australia or Nigeria or South Africa. Yet nowhere was the British literary encounter with imperialism so complex, or of so sustained a quality, as in India, the oldest and most important of Britain's conquered territories; hence this chapter's emphasis. But the British novel of Africa is also important, and its terms differ in interesting ways from those in which the British saw India. Before turning to Naipaul and Rushdie, we will therefore pause to examine some of its major motifs. According to Ahmad, postcolonial theory subsequently favors the work of the migrant intelligentsia of Third World origin based in the West. Said and his followers are taken to task for assuming that writers like Salman Rushdie (to whom Ahmad is consistently hostile) represent the authentic voice of their countries of origin. Instead, Ahmad locates them within the politically dominant class fraction of their host society, to which texts like Shame, like postcolonial theory itself, are in the first instance deemed to be addressed. Ultimately, Ahmad implies, a lot of such work needs to be placed within metropolitan discursive traditions such as Orientalism and Ahmad takes Said severely to task for failing to see how a text like Satanic Verses belongs to a long tradition of anti-Islamic sentiment in the West. When Third World culture 'proper' is addressed in postcolonial theory, Ahmad argues, most attention is given to those texts which 'answer back' to imperial and neo-colonial culture--for instance, the fictional ripostes to Heart of Darkness by figures as diverse as Chinua Achebe, Wilson Harris and Tayib Salih. According to In Theory, this attention to work that has been, in a crucial sense, interpellated by Western culture simply reinforces the traditional relationship between centre and periphery which underlay all discourse, political and cultural, of the colonial period. There is thus a damaging tendency 'to view the products of the English-writing intelligentsia of the cosmopolitan cities as the central documents' of the national literature of the country in question. In the process those aspects of Third World culture which are most genuinely independent of metropolitan influences and of allegiance to the national bourgeoisie, such as literatures written in regional Indian languages, are either neglected or ignored.

What is the true study of modern human emotion, th Essays

What is the true study of modern human emotion, th Essays What is the true study of modern human emotion, thought, and behavior, psychology or philosophy? This question's answer does not come easily to its solicitor; in fact, the two seemingly different subjects have a distinct and discernible relationship to one another. "Some things are up to us and some are not up to us. Our opinions are up to us, our impulses, desires, aversions, in-short whatever is our doing. Our bodies are not up to us, nor our possessions, our reputations, or our public offices, or that is, whatever is not of our own doing (Epictetus 1)." This citation, from a philosopher who lived around 100 B.C., illustrates the relationship between psychology and philosophy. When one examines the language housed within the passage he will understand, in order to lead a blissful life, one must have power over his reaction to an event and not let the event have power over his reaction. This effortless Stoic belief has lead to the development of a modern psychological therapy known as Rational-Emotive-Behavior-Therapy. This therapy uses a logical approach in order to solve problems with the human psyche.If one were to scrutinize the word "Psychological," he will notice the word "Psycho" which is related to the word "Psyche," which, in turn, means the human mind and its perception of consciousness. Upon further study of the word "Psychological," the person in question will notice the latter part of the word is "Logical" which deals with the processing and the capability of rational human thought; therefore, one can inf er that a psychological therapy must deal with the subjects awareness of his situation and his ability to rationalize his thoughts of such events. Rational-Emotive-Behavior-Therapy executes this conjecture to the letter. REBT is a reflexive approach to psychology that is gaining popularity. Today, REBT uses can be seen in everything from: combating unhealthy emotional outbursts, solving chemical dependencies, and improving a person's overall mental self-image. Foremost, one must understand Rational-Emotive-Behavior-Therapy in order to apply REBT to the above-mentioned modes of use. REBT is a therapy residing in a subdivision of psychological therapies known as Cognitive therapy, or an assumption based therapy relying on the premise that psychological problems are due to maladaptive patterns of thinking ( Hockenbury and Hockenbury 523). Gerald Metalsky Ph.D., Associate Professor of Psychology at Wisconsin's Lawrence University, explains cognitive therapy to be the process of "Identifying deprossogenic thoughts, evaluating these thoughts, and challenging the cognition of these thoughts in order to reduce future depressions ( Metalsky 23)." In other words, perception of life's events dictates emotion; however, perception is not always reality, cognitive distortions within one's mind are the actual culprit. Dr. Metalsky continues to explain with a model he uses to clarify the therapy to new patients. "We ta ke the ABC approach, which "A" is the antecedent event, "B" Is the belief one has regarding what has just transpired, and "C" is the consequence of the belief ( Metalsky 23)." This model shows the basic structure of all Cognitive therapies. For example, when a student fails an exam and the student concludes that he or she must be stupid. This is a classic example of an external event, interpreted incorrectly, creating a cognitive distortion in the mind of that individual. By understanding the outlining concept of Rational-Emotive-Behavior-Therapy, known as Cognitive Therapy, one is now ready to move on to the subject of REBT itself. What is REBT? Rational-Emotive-Behavior-Therapy, or commonly known as REBT, is a practical, action-oriented approach to coping with problems, and enhancing personal growth. The premise for Rational-Emotive-Behavior-Therapy is that a person's difficulties are the result of his or her faulty expectations and irrational beliefs (REBT facts 2). In order to restore emotional heath to the life of the individual one must utilize REBT. The therapy itself does not eliminate emotion; in fact, it emphasizes emotional involvement in every aspect of our thinking and our actions ( Metalsky 24). The therapy requires the patient to look at his situation and evaluate the emotion this situation evokes. When human emotion becomes too intense, as it often does, the person this emotion belongs to becomes unhappy. The quality of hi s or her life begins to deteriorate. It is at these times, the logical

Tambià ©n se admite, en casos extraordinarios, auto-peticià ³n por parte de un trabajador. Esto significa que puede solicitarse en los siguientes casos: Visa E-1, comerciante al amparo de un tratadoVisa E-2, inversor al amparo de un tratadoVisa H-1B, trabajadores extranjeros especiales o modelos. En este caso el gobierno ha anunciado la suspensià ³n temporal del proceso expedito que se reanudar el 10 de septiembre de 2018.Visa H-2B, trabajadores temporales para trabajos no agrà ­colasVisa H-3, trabajadores en prcticas o visitantes de intercambio en el campo de la educacià ³n especialVisa L-1, L-1B y LZ, trabajadores transferidos dentro de una empresa o subsidiarias de la mismaVisa O-1 para trabajadores con extraordinaria habilidad en Ciencias, Deportes, Arte, Educacià ³n o NegociosVisa O-2 para trabajadores que son un apoyo esencial para los titulares de una visa O-1Visa P-1, P-1S, P-2, P-2S, P-3 y P-3S, para deportistas individuales y de equipo, artistas y personal de apoyo para participar en un programa o evento à ºnico o que formen parte de un programa de intercambio cultural.Visa Q-1, para extranjeros participando en un prog rama de intercambio cultural internacional Visa R-1 para religiososVisa TN-1 y TN-2, para canadienses y mexicanos al amparo del Tratado de Libre comercio  (NAFTA, por sus siglas en inglà ©s)Visa EB-1, para extranjeros con habilidades extraordinarias, profesores e investigadores excepcionales y gerentes y ejecutivos de multinacionales.Visa EB-2, para profesionales con titulacià ³n avanzada o habilidad excepcional.Visa EB-3, para profesionales, trabajadores especializados y otros trabajadores El USCIS puede suspender temporalmente el procesamiento premium para alguna de esas visas. En el momento en que se escribe este artà ­culo no est vigente ninguna excepcià ³n. Es decir, se puede aplicar para todas las peticiones enunciadas. Costo del procesamiento premium y a quà © da derecho En la actualidad es de $1.225. Sin embargo, esta cantidad puede variar por lo que es muy conveniente verificar con la pgina oficial del USCIS. Si la solicitud se hace por internet utilizando el sistema de e-file, el pago puede realizarse mediante tarjeta de crà ©dito, dà ©bito o transferencia desde una cuenta de un banco en Estados Unidos. Por el contrario, si se envà ­a una solicitud en papel, el pago debe hacerse mediante un cheque de un banco en Estados Unidos o por money order. El pago da derecho a que el USCIS acuerde una respuesta en el plazo de 15 dà ­as naturales  a contar desde el dà ­a en el que se recibià ³ la solicitud de procesamiento premium con su correspondiente pago.   La respuesta no significa siempre que se obtiene la aprobacià ³n, sino que puede ser cualquiera de las siguientes: Una carta de aprobacià ³n de la peticià ³n de visa o de tarjeta de residenciaUna carta en la que se pide ms informacià ³n o documentacià ³n. Es lo que se conoce como Peticià ³n de Evidencia o RFE, por sus siglas en inglà ©s.Una carta en la que se notifica la intencià ³n de rechazar la peticià ³n. Se conoce como NOID, por sus siglas en inglà ©s.Y, finalmente, puede que lo que se notifique es que se   inicia una investigacià ³n porque se sospecha que la peticià ³n es fraudulenta o se ha mentido en la misma o se ha presentado documentacià ³n de apoyo falsa. En el caso de que USCIS haya respondido con una RFE o una NOID, el solicitante debe contestar en el tiempo que se le otorga en la notificacià ³n. Y, una vez que el USCIS recibe las  alegaciones o la documentacià ³n  adicional que pidià ³, tiene que responder en el plazo de 15 dà ­as naturales. En casos extraordinarios puede suceder que USCIS no responda dentro de los 15 dà ­as siguientesa  haber recibido la peticià ³n de tramitacià ³n premium.   En estos casos est obligado a regresar el coste del trmite y, adems, a responder inmediatamente.   Adems, el pago premium da derecho a utilizar un telà ©fono especial gratuito, el 1-866-315-5718, para resolver dudas o hacer preguntas relacionadas con la peticià ³n de la visa. Cà ³mo se solicita el pago premium para acelerar una peticià ³n con USCIS El formulario para solicitar la  aceleracià ³n de los trmites  es el I-907. La solicitud se puede realizar  conjuntamente  con el envà ­o de los formularios I-129,   en el caso de visa de trabajo temporal, o I-140, cuando se solicita la tarjeta de residencia por trabajo. Tambià ©n puede enviarse  por separado  en un momento posterior. Resaltar que la peticià ³n de tramitacià ³n acelerada sà ³lo la puede solicitar la empresa o emprendedor o su abogado  que son los que piden la visa. Nunca puede solicitarla el beneficiario de la peticià ³n, excepto en el caso en el que un trabajador de cualidades excepcionales solicita  una tarjeta de residencia para sà ­ mismo sin patrocinador. Por el contrario, el pago del formulario I-907 pueden efectuarlo no sà ³lo la empresa o  su abogado, sino tambià ©n la persona extranjera que resultarà ­a beneficiada por este trmite.  ¿A quà © no da derecho el pago premium para acelerar los trmites? En primer lugar, este pago no levanta los là ­mites anuales en el nà ºmero de visas que se pueden aprobar dentro de cada categorà ­a  por aà ±o fiscal. Es decir, si se ha agotado el nà ºmero de visas disponibles, con o sin pago premium hay que esperar al siguiente aà ±o fiscal para que se abra de nuevo la disponibilidad de visas. Tampoco da derecho a beneficios extra en los casos en los que existe una loterà ­a para determinar quià ©nes son los beneficiados de una visa, como por ejemplo con las visas de la familia H, en particular con la H-1B para profesionales. En los aà ±os en los que el nà ºmero de solicitudes excede en menos de una semana al total de visas disponibles para un aà ±o fiscal se procede a decidir por sorteo quià ©n es el ganador. El pago de procesamiento premium no da ventaja en esa loterà ­a. En tercer lugar, el pago premium no se admite en visas o en tarjetas de residencia cuyo proceso se inicia con formularios distintos al I-129 o al I-140. Por ejemplo, no es posible en las visas de turista, estudiante, intercambio, etc. Tampoco en las peticiones de green card por razà ³n de familia, algunas de las cuales sufren grandes demoras, como son los casos de  las peticiones de ciudadano americano para hermanos, hijos casados o hijos solteros mayores de 21 aà ±os o las de residente para sus hijos solteros mayores de 21 aà ±os.

Online research - Essay Example He never admitted to causing the injuries until the infant’s doctor confronted him and told him to take the infant to the hospital. Having spent only a few days in the hospital, the infant was released and her grandparents were given custody of her as well as the rest of her siblings. Day, who had been working as a dispatcher in the communications center of his local police department since 2007, was fired immediately following his arrest. Day is not set to make his first appearance in court until July 29, 2010. Various organizations and businesses that focus on child abuse are involved in the case, such as The Department of Children and Family and the Children’s Advocacy Center. The form of abuse that was involved in this case was physical abuse, or aggravated battery. Child neglect was also part of this case as Day did not immediately seek medical attention after his daughter sustained the injuries brought on by his carelessness and abuse. The injury report that had been filed after the infant spent time in the hospital showed that the fractured femur could be older than the fractured skull, which suggests that the infant could have faced earlier instances of child abuse. This bit of information has caused the case to be ongoing as investigators try to figure out how long the infant has dealt with the abuse of her father, if her siblings have acquired any injuries due to abuse, and if the mother of the children was aware of what was going on. The overall effect of the abuse and neglect on the infant was physical damage, though the damage is not considered to be long-term or life threatening. The infant is also now not living with her biological parents, which is a painful separation for someone as young as she is. As an infant, she requires the bond and nurture of her biological parents, especially her mother. Though the physical damage may not be long lasting, the mental and emotional state of the infant can alter with

Summary of Life of Pi by Yann Martel Essay -- essays research papers

The novel, Life of Pi, by Yann Martel, is about a young boy, Pi, and his survival on a lifeboat drifting in the Pacific Ocean. It is written in three sections, the second part, spanning from chapters 37 to 94, concerns the events on the lifeboat and what Pi experiences.

To sustain interest in this middle section of the novel, Martel uses a variety of techniques.

The Changing Role Of Women Essay examples - 578 Words

The Changing Role Of Women The role of women has changed in the last 100 years. However women have yet to achieve full equality with men. The role of women has changed in several ways. In the last century, only men went out to work. Women were expected to stay at home and take care of the household and the domestic side of things. This included the cooking, cleaning, laundry, ironing etc. However, the improvement in technology has meant that the household jobs have been made much easier and timesaving.

They will not ask this to men because it is not important when it comes to men, as they are not the parent that is constantly looking after them. One of the only times when a male parent is looking after their children is if they are a single parent or the mother is needed elsewhere. Also, if women were asked the question, do you intend to have any children, now or in the future, men arent as affected by the situation as women would be. If a woman were to fall pregnant, she wouldnt be bale to work as efficiently as she usually does, and also she will have to take maternity leave towards the end of her pregnancy. Employers know that men wont be as affected. Some employers think that men are more suitable for jobs and they work more efficiently, therefore men are more likely to be employed. This is an example of sexism that women have to put up with. Yet women did do a great job when the two World Wars were taking place. The men had to go to be soldiers and there was no one to take the jobs they were leaving behind.

The, The Gray Ghost, By Harper Lee - 1366 Words

Completing the Puzzle Harper Lee’s To Kill a Mockingbird, a novel about a young girl growing up in the racist South, tests one’s ethics and delves into some of the more profound human principles. The story of Maycomb, a sleepy Southern town, is rooted with the values, lessons, and symbolism of Harper Lee. Throughout the novel Harper Lee pays attention to even the smallest details, making sure that all writing has a purpose. That said, there are three books that Harper Lee mentions: Ivanhoe, The Gray Ghost, and Blackstone’s Commentaries. Although seemingly insignificant, the books that appear in To Kill a Mockingbird have symbolic and very much significant meanings, reinforcing what has been written, revealing parts of the novel, and†¦show more content†¦Mrs. Dubose won†¦ She was the bravest person I ever knew† (149). Atticus is subtly telling the story of Ivanhoe, reinforcing the struggles of both Mrs. Dubose and Wilfred of Ivanhoe. Ultimately, these characters act courageously, and despite not being accepted originally, regain the respect of their doubters as their true nature shows through. Blackstone’s Commentaries, one of the most important books on British Law (as well as an important influence on American Law), was written by Sir William Blackstone in an attempt to allow common folk to read and understand the law. Calpurnia briefly mentions the book while Jem and Scout are wondering how she and her son, Zeebo, learned to read and write, explaining that Blackstone’s Commentaries is influential in her ability to speak â€Å"proper† English., â€Å"Jem was thunderstruck†¦ ‘That’s why you don’t talk like the rest of ‘em’† (166-167). Jem comes to this realization after Calpurnia’s explanation, and understands what distinguishes her speech from that of other African-Americans of Maycomb. Although not made explicit in her writing, Harper Lee intends for Blackstone’ s Commentaries to be interpreted directly as an object symbolizing the law. As a result, the factor that differentiates Calpurnia and Zeebo from other African-Americans is not that they are literate and have the ability to speak proper English, but that they know the law.

Relevance of Swami Vivekananda’s Thoughts in Management Education Free Essays

Management education is a great beneficiary of Indian economic reform, where transformation from state controlled market to free market is imperative. In India, MBA degree has been perceived as a way of achieving assured careers and sound wages at early stage of life. The ambition of Indian youth today is to get a job in the business, industrial or service sectors and settle down well as early as possible. We will write a custom essay sample on Relevance of Swami Vivekananda’s Thoughts in Management Education or any similar topic only for you Order Now No doubt management education is needed an infusion of professional ability but the given value to society is equally important. Unfortunately, Management education in India has been so distorted and diluted in its execution as to lose nearly all the social intent. In whole spectrum, the role of intuition, value and social recognition gets short shrift in the Management education. Emphasis is only on the knowledge content, on which examination is conducted. All other useful knowledge areas and skills are vastly neglected. Like spiritual knowledge does not find an appropriate place in the curriculum. Therefore students have no opportunity to know about their faith, culture and values. The knowledge they gain is mainly bookish and is not backed by practical experience. About a century ago, Swami Vivekananda had envisioned a vision on education and had categorically pointed out that true education is not the amount of information that is put into one’s brain. The human mind is not a bottomless dry well, which has to be filled in with buckets of information by the teacher. He had said that education has more to do with assimilation of ideas and developing ‘a mind of the same material as that of which the thunderbolt is made’. He suggested, was to be done with the help of ‘Western science coupled with Vedanta †¦ and faith in one’s own Self’. What type of management education will provide this enlightenment? According to Swamiji, ‘The training by which the current and expression of will are brought under control and become fruitful is called education’. He wanted a man-making education ‘by which character is formed, strength of mind is increased, the intellect is expanded, and by which one can stand on one’s own feet’. Swamiji emphasized need of following points in education system. * Role of teacher * Spirituality * Accessibility of knowledge * Plural attitude Role of teacher Both the teacher and the student are active participants in the teaching-learning process. The teacher should look upon the student not as a mere physical being but as a living and dynamic mind that struggling to manifest the light of the infinite soul. The teacher should facilitate this process of self-discovery. Teacher should not try to fill the mind with information and knowledge only. Instead he should attempt to unfold the creativity within by stimulating and strengthening the mind. The teacher has to carefully nurture the conviction and faith in the mind of the students. Needless to say, teacher requires faith, patience, perseverance and firm conviction. This ideal of faith in oneself, or Atmashraddha, would be greatest gift of a teacher to the student. Spirituality Swami Vivekananda brings this out very clearly in his immortal works. He said: If there is any land on this earth that can lay claim to be the blessed Punya Bhumi †¦ the land where humanity has attained its highest towards gentleness, towards generosity, towards purity, towards calmness, above all, the land of introspection and of spirituality—it is India. †¦ the Indian race never stood for wealth. Although they acquired immense wealth, perhaps more than any other nation ever acquired, yet the nation did not stand for wealth. It was a powerful race for ages, yet we find that that nation never stood for power, never went out of the country to conquer. Quite content within their own boundaries, they never fought anybody. The Indian nation never stood for imperial glory. Wealth and power, then, were not the ideals of the race â€Å". Swami Ji enlightened that human peace and happiness depends not on the wealth they possess, or the power they wield, or the scholarship they have acquired, but by living a life of renunciation and having the awareness that they are part of the entire universe and that all constitute one family, V asudhaiva Kutumbakam. Accessibility of Knowledge Swami Ji emphasized on accessibility of education . He said: If the mountain does not come to Mohammed, Mohammed must go to the mountain. If the poor cannot come to education, education must reach them at the plough, in the factory, everywhere. How? You have seen my brethren. Now I can get hundreds of such [all-renouncing sannyasins], all over India, unselfish, good, and educated. Let these men go from village to village bringing not only religion to the door of everyone but also education†. Students must also be educated about the social world—the nature of the society he lives in, the laws that guide it, and the culture it has evolved. Plural Attitude In era of globalization people are coming closer than ever to each other. People of different languages, beliefs, religious faiths, political convictions and ways of life have come to live closely. Everyone has a right to his way of life. Dogmatism and bigotry have no place in globalized world. Therefore management education must instill these qualities in students. Thus, Swami Ji’s thoughts on education are like an ocean. The more we ponder the more we get. We have to pursue the ideas of Swami ji with a deep sense of commitment to achieve objectives of education.

Types of Cardiac Arrhythmia Resulting From Centrifugal Acceleration

Abstract Cardiac arrhythmia is one of the many health conditions that form the basis of aviation medicine. The absence of adequate information around the condition necessitates studies to that effect. The current paper sought to determine the types of cardiac arrhythmia that result from aviation related movement.Advertising We will write a custom research paper sample on Types of Cardiac Arrhythmia Resulting From Centrifugal Acceleration specifically for you for only $16.05 $11/page Learn More The study relied on findings made in centrifugal training experiments, where subjects are usually placed in a human centrifuge. The objective was to expose the subjects to +Gz forces, which are similar to the ones in a military jet or a commercial flight. During such exercises, the tolerance level of the subjects was determined relative to the G-forces. It was found that sinus arrhythmia, premature atrial contraction, premature ventricle contraction, and atrial fib rillation are the common cardiac arrhythmias during such exercises. Introduction Aviation Medicine An Overview There are certain health-related problems that are unique to the aeronautical and aviation industry.[1] Rayman points out that aviation medicine can also be referred to as flight or aerospace therapy.[1] The idea behind this kind of healthcare is the need for a medicinal approach in tackling the wellbeing of people in aerospace industries. Pilots and astronauts are good examples of individuals who are covered by aviation medicine. The principle behind this field is the fact that the patients find themselves physiologically affected by aviation-related factors, such as gravity. Advancement in the aerospace and aviation sectors imply that most of the aforementioned factors will increasingly affect the persons in the industry. Hanada, Hisada, and Koichiro affirm that progress is inevitable in the aviation industry.[2] An example is the case of air force pilots. The need to dev elop faster and effective jets means that the aerodynamic factors will be modified. Consequently, the pilots end up being affected by some of these forces. The advancements made in aviation medicine rely on its relevance to the world of aerospace. Whinnery indicates this importance by outlining the fact that the United States Air Force (herein referred to as USAF) has a School of Aerospace Medicine.[3] Such institutions justify the reasoning that research in aviation medicine is important. In a study to determine the state of affairs in Singapore in relation to this field, Gan, Low and Singh focus on the military and commercial flight areas.[4] In these fields, there is constant development of new and state-of-the-art machinery. However, as aforementioned, the same comes with consequences like increased arrhythmia.Advertising Looking for research paper on health medicine? Let's see if we can help you! Get your first paper with 15% OFF Learn More Technological innovati ons in medicine are required in such fields as aviation physiology and performance maximization.[4] Other areas in which advancement is required include the selection of medical standards and protection of aircrew from communicable diseases, which may arise during a flight. However, for the purposes of this paper, discussions will revolve around the physiology aspect of aviation medicine. G-Forces in air planes Airplanes are constructed in such a manner that they respond to the laws of aerodynamics.[1] The operation of these laws relies on gravity and how to overcome it. Whinnery brings out the understanding that gravity, as a force, is observed as acceleration.[2] The implication is that there is motion involved. Going by the arguments made in Newton’s laws of motion, it is evident that gravity is characterized by several forces. The study restricts itself to the forces exerted on an aircraft due to gravity, which is referred to as ‘g-force’. According to Gan et al.,[4] g-forces are considered as accelerations, as previously indicated. As a result, one can determine these forces on the basis of their respective weights. By virtue of the acceleration nature of gravity, the g-forces appear to multiply the weights of a given mass. In the context of an airplane, these factors tend to reproduce the weight of the unit mass of the persons in the jet. To appreciate how a pilot will experience this multiplier effect, one ought to obtain the sum of the non-gravitational forces acting on them. The aforementioned non-gravitational forces are considered as the proper accelerations.[1] Their effects include stress and strain on persons in an aircraft. In their study, Whinnery[3] makes the claim that high amounts of g-forces are destructive to the aircraft and to the people. Effects of g-forces on human anatomy G-forces cause strain and stress on the bodies in an aircraft. In line with this, the elements have a physiological effect on human bodies.[1] Ha nada et al.[2] affirm this hypothesis in their study on the effects of g-forces on military pilots. Most of the components of the human anatomy have mass. As such, the effects of stress and strain on them vary. Hanada et al.[2] indicate cerebral perfusion as a major impact of these forces. In such cases, the patients tend to suffer from a condition known as G-induced loss of consciousness (herein referred to as G-LOC). Such conditions are common among military pilots during the maneuvers displayed by the fighter jets. Arrhythmias is another common phenomenon resulting from the g-forces, especially in instances where flight crew are taken through centrifuge training.[4] In such cases, the pilots are subjected to the same conditions as those of a plane in the air. Consequently, the developments tend to alter the rhythmic patterns of an individual’s heartbeat. The effects of g-forces are so serious on the human anatomy to the extent that Hanada et al.[2] propose the presence of specialists during centrifuge training.Advertising We will write a custom research paper sample on Types of Cardiac Arrhythmia Resulting From Centrifugal Acceleration specifically for you for only $16.05 $11/page Learn More Effects of G-Forces on the Heart General effects An analysis of g-forces makes it apparent that human anatomy is severely affected by stress and strain, as illustrated in the previous section. Advances in aerospace technology imply that human body will continue to be subjected to such forces to determine its tolerance.[1] For the purposes of this study, it is important to understand the effects of g-forces on the heart as an organ in human anatomy. Cardiac arrhythmia The functioning of the heart is largely attributed to its electrical properties.[1] The stresses and strains brought about by the g-forces tend to affect the organ’s electrical attributes. As a result, the heart beat is altered. Conditions of this nature are what are referred to as cardiac arrhythmia. The condition is not age or gender specific. Whinnery[3] points out that the condition if often not fatal. However, studies illustrate that cardiac arrest is associated with arrhythmia.[2] Cardiac arrhythmia can occur in one of the compartments of the heart.[1] The same explains why there are different types of the said condition. Rayman[1] points out the existence of four types of cardiac arrhythmia. The first is supraventricular arrhythmia, which is characterized by a fast heart rate.[1] Secondly, there is bradyyarrhytmias. The condition arises when the heart beat is extremely low. In such cases, the blood hardly reaches the brain. The third type is ventricular arrhythmias. The occurence is associated with the lower chambers of the heart.[1] Finally, there is premature beats. It is a type of arrhythmia associated with the upper atria of the heart. The ‘premature beats’ are an indication of a mild form of arrhythmia, whose symptom s are not easily noticeable.[5] Cardiac arrhythmia in aviation medicine The aviation industry is a sensitive area, which involves out of space explorations and normal flights. The machines involved are quite complex. The sophistication requires the complete application of the pilot’s cognitive abilities. Within the broad spectrum of aviation medicine, cardiac arrhythmia falls under the physiological effects. The heart plays an important role in human anatomy.[6] As such, studies have been conducted to illustrate how best to overcome the condition. Factors influencing g-force provoked arrhythmia During centrifugal training, the participants are subjected to +Gz forces. The procedure leads to stress that affects human anatomical functions. It is evident that cardiac arrhythmia results from the effects of the G-force on the heart. The rhythms are distorted from their normal patterns.[7] It is important to appreciate the factors that influence the occurrence of arrhythmia due to the G-forces. Over the years, aviation medicine has relied on centrifugal training to obtain information about cardiac arrhythmia. Such information includes the various types of the condition and their influencing factors.[7] Experiments carried out to determine this rely on the use of human centrifuges, which are found in special units. The most common areas where such apparitions are found include special aviation medical departments in military wings.Advertising Looking for research paper on health medicine? Let's see if we can help you! Get your first paper with 15% OFF Learn More One of the factors that influence cardiac arrhythmia during centrifugal training is the magnitude of the +Gz. Ewalina and Lech[7] proved this in a study in which they sought to determine hemodynamic changes resulting from centrifugal acceleration and the corresponding cardiovascular responses. The study reveals that an acceleration of 1Gz is responsible of acute hemodynamic changes. The same magnitude of acceleration was found to be an activator of cardiovascular responses, arrhythmia being one of them.[7] Anti-G straining maneuvers (herein referred to as AGSM) are other factors that influence g-force-provoked arrhythmia. Ewalina and Lech[7] point out that the same has a direct effect on the nervous system, which impacts on the heart’s electrical properties. Such measures are seen as an attempt to reduce the effects of g-forces. They limit the impacts of +Gz on the electrical characteristics of the heart. Other factors include the health status of the subject and the duration of exposure. Latent cardiac medical histories give mixed results. Exposure durations increase the chances of cardiac arrhythmia, which further aggravates the severity of the conditions. Materials and Methods Introduction The current study is hinged on the hypothesis that centrifugal acceleration results in cardiac arrhythmia.[1] The research relies on a series of peer reviewed articles, which provide a detailed discussion of the topic. More importantly, the articles relied on address the issue of g-forces and their effects on human subjects. They illustrate the various types of arrhythmia and their relationship with g-forces. +G Acceleration and Corresponding Detection of Cardiovascular Responses In an experiment, Vettes, Viellefond, and Auffret[6] determined that g-forces have a corresponding cardiovascular response from the heart. The researchers deduced this by carrying out detailed studies on the issue. The subjects used were all male and individually volunteered for the exerci se. The studies were carried out in a laboratory in France. The location, known as the Aerospace Medicine Laboratory of the Flight and Test Center, contained the equipment necessary for this research.[6] The male volunteers had an average age of 37 years.[6] After the preliminary medical check-ups were concluded, all the subjects were found to be medically fit for exposure to g-forces. Preliminary tests carried out at the Central Medical Examination Centre for Flying Personnel, which is situated in Paris.[6] Thirteen of the participants did not have prior exposure to centrifugal acceleration. According to Vettes et al.,[6] +Gz g-forces were required for the study. The said forces are attained when a human centrifuge is rotated longitudinally. The specific centrifuge used in this research had a vertical rotating axis, whose arm was six meters.[6] A gondola is attached at the arm’s extreme end. Human subjects occupy this space. The centrifugal acceleration in this regard is obt ained by means of a perpendicular rotation of the arm relative to the gondola. During this rotation, the apparatus moves along the axis, exposing the subject to the +Gz forces arising from acceleration. To ascertain the responses, certain cardiac parameters are taken into account.[6] Such parameters as the subjects’ rate of heartbeat and arterial pressure were are determined. The study by Vettes et al.[6] required the stoke volume and the subjects’ visual fields to be recorded as part of the preliminary medical analysis. Each of the electrocardiographs was analyzed by means of a special electrode. The electrodes are placed on 3 locations on the subjects’ body. The first two are placed on each of the axillae, while the third is placed on the lumbar spine. In so doing, the researchers minimize the noise that would otherwise be present due to the muscle-related contractions. The arterial pressure on the other hand is obtained by means of a syphgamanomter.[6] The sa id machine is normally inflated by means of an electrovalve that is remotely controlled. To obtain the actual pressure in a subject, a curve on the machine is needed.[6] In addition, there is a microphone placed at a strategic point to detect specific noises. In the study, the researchers were able to record their patients’ rates of heartbeat using a phonocardiograph. However, there are exceptions where the heart rate is determined by taking measurements of 10 systoles from the machine. Safety Criterion The study by Hanada et al.[2] sought to develop a safety criterion for centrifugal training. The study relied on pilots from the Japanese Air Self-Defense forces. Each of the subjects was conversant with F-4, F-15 and F-2 fighter jets.[2] Such familiarity was a requirement to be part of the study. It was meant to ensure that the subjects were all familiar with increased G-forces due to the aircrafts’ high rates of acceleration. As expected, there was a preliminary medic al examination carried out on each of the participants.[7] In addition, the subjects were taken through a pre-determined duration of centrifugal acceleration to obtain specified results. The study created several profiles to analyze the effects of different +Gz forces. The data analysis phase was characterized by anonymity. The names of the pilots were not included in the profiles. G-Force Tolerance In their study, Blue et al.[5] examined levels of tolerance associated with g-forces during centrifugal training. The study revolved around subjects with an interest in spaceflight. The participants were part of Virgin Galactica crew and would- be passengers. An equipment referred to as a ‘Space Training Simulator’ was used in the study. The machine operates like a human centrifuge. Prior to the experiment, a medical examination was carried out. Afterwards, the subjects were taken through an anti-G straining procedure. There was a descriptive representation of the data colle cted in the study. Cardiac Arrhythmias in Flight and Centrifuge Simulations In their article, Ewalina and Lech[7] argue that centrifuge acceleration has an effect on cardiac arrhythmia. Consequently, their study analyzed the two scenarios in which such acceleration is achieved. They examined the rhythm balances when the subjects are in centrifuge training and in actual flight. Ewalina and Lech[7] point out that the two instances have similarities and differences. Ultimately, the research sheds more light on cardiac arrhythmia resulting from centrifugal acceleration. In the study, Ewalina and Lech[7] relied on 20 experienced pilots and 20 students. The student pilots were selected from a group of 3rd and 4th year cadets in the Polish Air Force Officers’ College. According to Ewalina and Lech,[7] the average age of the experienced pilots was 35.3 years. There was an allowance of 4.9 years in the positive and negative extremes. The average height was 176.6 cm, while body mass wa s 79.3kg.[7] The average flying hours of the experienced pilots was estimated at 2620. The trainee pilots, on the other hand, had an average age of 21.9 years and median height of 178.2 cm.[7] Their mean body mass was 78.7kg. They had an average of 252 flight hours on their records.[7] One of the requirements for participation in the experiment was that none of the pilots should take any form of medication. Ethical issues were also taken into consideration, where the participants were required to submit a written consent. The approval to conduct the study was granted by an ethics committee constituted by the ‘Polish Air Forces Institute of Aviation Medicine.’[7] The study required the subjects from the two groups to carry out flight protocols in pairs, where one acted as a pilot, and the other as a passenger.[7] Each of the subjects was required to make 2 flights. In the first flight, the subject was required to act as a ‘pilot’ (herein referred to as AF). The second flight demanded that they act as a passenger (herein referred to as PF). According to Ewalina and Lech,[7] the participants were required to take a break in-between the flight schedules. The study gave an allowance of 1 hour as the duration of time that each pilot should take before taking part in the next flight. To attain consistent results, all the subjects made use of the same TS-11 ISKRA Jet.[7] Once all the pilots had made their required flights, the researchers took a break of two days. During the break, the subjects underwent human centrifuge tests. It is important to note that the subjects did not wear G-suits during the study. The omission was meant to allow the +Gz effects to be conclusively examined. The forces were generated from the maneuvers carried out in the flight program. They ranged from 0.57 G.s-1 to 4Gz when the maneuver involved three successive turns.[7] With regards to the split S maneuver, the acceleration was recorded between 1.7G. s-1 and 5.6 G z.7 The ‘two-successive loop’ maneuver was characterized by an acceleration of 1.4G.s-1 to 5.0Gz. The other maneuvers carried out were the immelman and the one turn. The former had an acceleration of 5.6Gz, while the latter gave results identical to all the other maneuvers.[7] The results from the flight protocols were recorded separately. As aforementioned, the study carried out a centrifuge test. The same was realized using a centrifuge with a radius of 10 meters.[7] The equipment was provided by the Acceleration Tolerance Laboratory, which is situated within the Institute of Aviation Medicine. The latter is a department of the Polish Military. At the resting level, the acceleration was +1.4Gz. Thereafter, it was increased by 1G.s-1 to a maximum of 7Gz. When the human centrifuge was involved, the accelerations were set at levels similar to the aerobatic maneuvers.[7] +GZ and the Electrocardiographic Response Whinnery[3] sought to establish that the g-forces experience d during centrifuge training have an effect on an individual’s electrocardiographic (herein referred to as ECG) response system. The study involved a total of 59 subjects. According to Whinnery,[3] the research relied on the responses of the flight surgeons that developed the acceleration profiles of the subjects. The participants were drawn from the United States Air Force and the United States Navy.[3] The two training profiles developed for the study included the gradual and the rapid onsets. According to Whinnery,[3] observation of the subjects was carried out based on their respective ECG dysrhythmias. The first profile was developed when the participants were allowed to put on a standard anti-g suit. Whinnery[3] points out that the suit was not inflated. There various reasons why inflation was omitted. The major objective was to ensure that the subjects were relaxed and that their loss of peripheral vision was gradual. The maximum limit of +Gz was estimated at +9Gz. It is important to note that the tolerance levels during the centrifuge training were recorded from 2 extremes. There was the relaxed and the straining levels of tolerance.[3] In both cases, the aim was to obtain the proficiency of the anti-g element in the experiment.[3] The researchers analyzed the various symptoms exhibited by the subjects. To achieve this, the results were computed in terms of the average, standard deviation, minimum, and maximum.[3] Whinnery[3] used the ages of the subjects to estimate the results. Of particular interest was the comparison between the ectopy occurrences among the subjects. The incidences were analyzed by means of a correlated proportions test referred to as McNemar.[3] An elaborate outline of the results is discussed in the subsequent sections of this paper. The objective, as already mentioned, is to build on the hypothesis of the current study. The discussions will involve results from studies similar to the ones referred to in this section. Resu lts Introduction to the Results From the materials and methods discussed in the previous sections, it is apparent that there is enough evidence to support the hypothesis made in this paper. The evidence suggests that cardiac arrhythmia is caused by g-forces that result from centrifugal acceleration.[5] The results of previous studies conducted in this field highlight the various types of arrhythmias and the effect of centrifugal acceleration on the rate of heartbeat. In addition, the findings made illustrate the various cardiovascular parameters related to arrhythmia. In line with this, analysis of this condition in relation to centrifuge is outlined in this section. Types of Arrhythmias As aforementioned, there are multiple types of arrhythmias. Each of them has unique characteristics that set it apart from the others.[6] In a study to determine the safety measures needed to be put in place during g-flight training, Hanada et al.[2] found out different types of this condition. The findings are illustrated in Table 2 below: Table 1: Types of cardiac arrhythmia Number of Participants Percentage of Occurrence (%) Type of Arrhythmia 114 58.5 Single PVC 95 48.7 Sinus Arrhythmia 63 32.3 Single PAC 19 9.7 Paired PVC 5 2.6 Ventricular tachycardia 3 1.5 Paroxysmal supraventricular tachycardia 3 1.5 Repeated PAC 1 0.5 Paroxysmal Atrial Fibrillation 1 0.5 Ventricular bigeminy or trigeminy Adapted from: Hanada et al.[2] The study by Hanada et al.[2] reveals 9 types of cardiac arrhythmia associated with centrifuge acceleration. The figures listed in table 1 above were obtained from a research conducted by the Japan Air Self-Defense Force (herein referred to as JASDF). The most common condition recorded during the study was single premature ventricular contraction (herein referred to as PVC) at 58.5 percent. The occurrence of both Paroxysmal Atrial Fibrillation and ventricular bigemny or trigemny was recorded at 0.5% in one of the participants, maki ng it the least common of all. Centrifugal Acceleration and its Effects on the Rate of Heartbeat As previously mentioned, centrifugal acceleration has an effect on human anatomy. The effects of this phenomenon on human body vary between different organs. Studies reveal that centrifugal acceleration gives rise to g-forces. As such, it follows that their effects on the heart touches on its rhythms, leading to cardiac arrhythmia.[7] In their study, Whinnery[3] affirms that g-forces affect an individual’s heart rate. Table 2 below illustrates results of the study by Whinnery.[3] The effects of the forces on the human heart are documented in the table. Table 2: G-force exposure and corresponding heart beat rates Lown grade Ectopy Definition Subjects with highest Lown grade 0 Absence of ventricular premature depolarizations 12 1 5 PVC 31 2 5 PVC 3 3 Multiform PVC 1 4A Paired PVC 8 Source: Whinnery[3] In this research, Whinnery[3] relied on one type of cardiac arrhyt hmia. As illustrated in table 2 above, the study examined the rates of heartbeat in relation to the effects of exposure to +Gz forces. The analysis is based on a Lown grading system. Such a system is used to classify heartbeats with regards to cardiac arrhythmia.[8] Whinnery[3] selected a cluster from the known classifications, as shown in table 2. The experiment analyzed results from a total of 59 participants. It was found that +Gz forces affected an average of 11 subjects. The same is inferred from the data in table 2. Cardiovascular Parameters Studies aimed at examining the effects of centrifugal acceleration rely on specified cardiovascular parameters. Vettes et al.[6] posit that the +Gz forces arising from centrifugal acceleration rely on such factors. They determine such responses as cardiac arrhythmia. The said parameters include an electrogram and the visual field of the subject. In addition, the heart rate and humeral arterial pressure of the participants are factored in t he study. They make up the cardiovascular parameters recorded during such experiments.[6] Vettes et al.[6] point out that increased exposure to g-forces was followed by a corresponding increase in the rate of the individual’s heart beats. The results from their experiments illustrated that peripheral loss of vision among the subjects was an indicator of the effects of the +Gz forces. The latter is regarded as a key symptom indicating the onset of cardiac arrhythmia. The study by Vettes et al.[6] revealed that the highest recorded heart beat per minute was 113, whereas the lowest was 84. In terms of pressure, Vettes et al.[6] illustrated that increased exposure to these forces (up to levels of +3 Gz) resulted in a corresponding rise in arterial pressure. To this effect, blood pressure is treated as an essential parameter in understanding cardiac arrhythmia. The same explains the effects of exposure to g-forces. The scenario is similar to electrocardiographic recordings, which vary depending on the accelerations. In their study, Vettes et al.[6] point out that increased heart pressure was the cause of arrhythmia. The reason is that the pressure led to atrio-ventricular dissociation. Effects of Centrifuge Training on the Heart The major focus of this study is centrifugal acceleration and its effects on human anatomy.[9] Aviation regulations require pilots (and in some cases passengers) to undergo some level of centrifugal training. Such trainings simulate the acceleration likely to be experienced in fast moving aircrafts. An example of such instances involves commercial space-crafts.[5] The high acceleration associated with such crafts requires some training to acquaint the persons with the g-forces. Blue et al.[5] carried out a similar study in which occupants of a spaceflight were subjected to centrifugal-stimulated sub-orbital flight. The objective was to create conditions similar to those in a fast moving aircraft. The participants in the study by Blue et al.[5] were all healthy. The simulation was expected to provide information on how g-forces affect the heart. It was also expected to shed light on the influence of the forces on the occurrence of cardiac arrhythmia. Their study used a total of 81 participants[5]. The research by Blue et al.[5] required healthy individuals. As a result, all the participants were subjected to medical screening.[6] Consequently, the initial number was reduced to 77 subjects. Out of this, 65 were men, while 12 were women. Another batch of 21 participants was subjected to cardiac examinations to check for any latent complications. The medical examinations revealed that 16 had histories of hypertension, while 5 had diabetes. Another 5 had undergone a coronary heart bypass. In addition, 17 participants had a history of hyperlipidemia. Prior to the simulation, there were 2 individuals who were found to have severe cases of peripheral vascular disease. The objective of these tests was to obtain exact re sults from the simulations. The aim was to ensure that the findings made were due to g-forces from centrifugal acceleration and not from latent conditions. The participants with medical histories had little complaints from the centrifugal acceleration in comparison to those without backgrounds of medical conditions. However, both sets of participants complained of nausea. The same is common in cases where subjects are exposed to high centrifugal acceleration. Another effect of this development was greyout. To this end, participants complained of incidences of mild greyout. Interestingly, none of the participants experienced any form of G-LOC. There were, however, incidences where the participants would perform head movements with the sole objective of self-inducing sensations similar to coriolis. Discussion Overview From the various experiments highlighted in the current study, it appears that cardiac arrhythmia is caused by g-forces associated with aerodynamics.[10] The various stu dies made reference to centrifugal acceleration. It is not possible to obtain results from the specific aircrafts that the researchers used to generate centrifugal acceleration. As a result, most studies depend on simulations of conditions found in an aircraft.[11] During such instances, the subjects are rotated at speeds that are almost equivalent to those in an aircraft The objective of such simulations is to expose the subjects to g-forces from acceleration.[12] The specific elements observed are the +Gz forces. The designation ‘z’ implies that on a 3 dimensional plane, the said forces act on the z axis. Their effects on the subject are longitudinal. In addition, they are the most common forces that affect the rhythm of an individual’s heart when in flight.[13] The different levels of exposure to g-forces are a contributing factor to the occurrence of the various types of cardiac arrhythmia. The study by Hanada et al.[2] highlighted three types of arrhythmia c ommon among pilots, especially in military jets. The three were identified as PAC, PVC, and sinus arrhythmias. According to Hanada et al.,[2] the three occurred due to the variant levels of exposure to +Gz. For instance, sinus arrhythmia occurs in instances where subjects are exposed to high g-forces. In such cases, the resulting levels of stress are high. The same has an effect on the heart rate. It distorts the rhythm of these rates once the subject comes to rest. It is noted that PVC and PAC are the most common types of arrhythmia that result from interactions with high-G training.[14] Hanada et al.[2] addressed this issue by pointing out that the two are common in normal day-to-day exercises. The researchers found it prudent to do away with centrifuge in cases where subjects exhibited PAC and PVC.[2] The argument is strengthened by the assumption that the two arrhythmias are a normal occurrence among subjects. The study by Hanada et al.[2] introduced the element of grading the r ate of heartbeat rhythms among subjects. The system is essential in determining the degree or severity with which arrhythmia exhibits itself.[15] In this grading system, arrhythmias that are recorded at a grade of three or higher are regarded as severe. It is noted that 10% of the subjects in the study by Hanada et al.[2] exhibited a paired condition of PVC. The researchers argue that the condition is a direct physiological response to the stress experienced during the centrifugal acceleration in training sessions. The Lown grading system for ectopy was developed against the backdrop of the need to characterize the different types of arrhythmia. The same explains why, in the study by Hanada et al.[2], PAC and PVC are graded according to the degree of exposure to +Gz. An example is in the case where there is paired PVC and PAC, while at the same time single cases of PAC and PVC are noted. In both cases, the Lown format becomes vital in highlighting the severity of the different types of arrhythmia. The Lown system is one of the advancements made in aviation medicine. It is used to determine the types of arrhythmias that are permissible in centrifugal training. An example is evident in the study by Hanada et al.[2], where the system is used to sanction centrifugal training in cases where subjects exhibit paired PVC. However, training sessions are terminated in cases where the arrhythmias go beyond a specific threshold.[2] In such cases, the severity of the condition is determined by such factors as proaxysmal atrial fibrillation. Hanada et al.[2] posit that there are certain tachycardiac arrhythmias that reduce tolerance to G-stress resulting from centrifugal acceleration. In such cases, the subjects exhibit PSVT and VT. Their study revealed that PVST is possibly a major cause of loss of consciousness during centrifugal training.[15] The findings made in the current study are best understood from the perspective of a detailed discussion of centrifugal accelerati on and its effects on the heart. In so doing, the researcher aims to prove that cardiac arrhythmia is a result of centrifugal acceleration. In this section, the specific types of this condition are analyzed in detail. Protocols for Centrifugal Acceleration The findings in this study reveal that centrifugal acceleration is an important component of aviation medicine.[16] The process creates an environment that is similar to that experienced in fast moving aircrafts like fighter jets. Such individuals as military pilots and astronauts are the most affected by the G-forces arising from the acceleration of high speed aircrafts. It follows that such individuals require some form of training to acquaint themselves with the strenuous conditions and to help them bear with the stresses brought about by the forces. Centrifugal training, as already indicated, is the process through which pilots and other crew members are subjected to controlled conditions of G-stress. During such sessions, avi ation medical personnel examine individual subjects’ tolerance to G-forces.[2] It is important to take the subjects through certain protocols. Such a move is necessary as it helps in the attainment of accurate results from the exposure to the said forces. Several studies are used to elaborate the importance of these protocols as indicated in the ‘methods’ section of this paper. The first and most important protocol to follow in centrifugal training is preliminary medical check-ups.[1] The procedure is evident in the studies by Hanada et al.[2] and Whinnery[3], where the subjects are screened for heart related complications. The objective of such preliminary medical examinations is to ensure the effects of G-stress exposure are not confused with the symptoms of latent medical conditions. The second protocol during centrifugal studies is the exposure levels.[3] During the training exercises, the subjects must be exposed to varying levels of +Gz so that a proper com parison can be arrived at. For instance, Whinnery and Hickman[8] sought to study mitrial prolapsed and thus relied on centrifugal acceleration. Their subjects were exposed to stress levels of 1G.15s-1 which were gradually increased. There was also another exposure referred to as the rapid onset exposure in which the subjects experienced g-forces of 1 G.s-1. The initial tolerance level is essential in evaluating cardiovascular reflexes.[8] On the other hand the second tolerance level are useful in determining the subjects’ tolerance in terms of the hydraulics. During these exposure levels, in centrifugal training, it is expected that the subjects end up experiencing total loss of their peripheral sight. The aforementioned protocols are key in ensuring that the results are obtained as expected.[8] Arrhythmia Resulting from Centrifugal Training Overview From the findings in this paper, it is apparent that the rhythm of the heart is distorted by the G-stresses during centrifugal training.[17] As previously mentioned, centrifugal training involves rotation of subjects in a contraption referred to as a human centrifuge. The objective is to expose the participants in such exercises to +Gz forces.[3] Consequently, the individuals in such studies are observed to determine how the G-forces affect their human anatomy, of which the heart is a vital component. The contents of the articles referred to in the current paper reveal that there are 4 major types of arrhythmias that result from centrifugal acceleration.[4] The four include sinus arrhythmia, premature arterial contraction, arterial fibrillation, and premature ventricular contraction.[3] In order to categorize each of the mentioned arrhythmias, the author of the current study made observations depending on the levels of +Gz exposure. A detailed discussion is provided in this section. Sinus arrhythmia According to Rayman,[1] the heart has a specific rhythm to which it beats. Consequently, any external force l ike g-stress tends to distort the normal pattern of this organ, resulting in what is now known as cardiac arrhythmia. From the articles reviewed in this study, subjects in centrifugal training experiments were found to exhibit sinus arrhythmia among other complications known in aviation medicine.[9] The study by Hanada et al.[2] revealed that this complication is common during centrifugal training, where the subject’s heart rate normalizes immediately after a rapid heart-beat rhythm. Interestingly, there were subjects who exhibited this particular kind of arrhythmia prior to centrifuge acceleration and the subsequent exposure to the +Gz forces. As illustrated in table 2, the occurrence of the SA in the participants was recorded at 48%. It is important to appreciate that the high occurrence rate is not really due to the centrifugal acceleration. Hanada et al.[2] argue that the condition is a normal occurrence, especially among persons involved in physical training. Studies ill ustrate that the normal rate of a healthy adult lies between 60 to 100 beats every minute.[1] However, some studies indicate that the pattern varies between the genders. A normal female’s heart rate, for instance, is estimated to fall between 47 and 103 beats for every minute.[17] In men, the estimated rhythm is placed at the range of 43 to 102 beats per minute. Alterations in heart beat rhythm due to sinus arrhythmia are not fatal. There are cases where the condition cannot be detected. As such, members of a flying crew who are found to have the condition are not in danger. Premature arterial contraction (PAC) The human heart is fitted with a pace maker that has electrical characteristics.[1] as a result, when this part is exposed to external forces, there are distortions in its normal functioning. Centrifugal acceleration, as aforementioned, has an effect on the organ. The resultant +Gz forces give rise to G-stress. As mentioned earlier, these stressors tend to affect the n ormal workings of the human anatomy. The pacemaker is among the body parts affected. As a cardiac arrhythmia, premature arterial contraction is a phenomenon where the heart’s pacemaker emits signals before the ‘stipulated’ time.[18] The maker is located above the ventricles, meaning that these chambers respond to the distorted signals. As a result, the heart’s rhythm is altered by the ventricle’s ‘irregular’ response. An arrhythmia of this kind is usually common when an individual is stimulated either through exercises or as a result of such beverages as coffee. However, the same is also true when an individual undergoes centrifugal training.[2] In the study by Hanada et al.,[2] PAC exhibited itself in a number of the subjects used in the experiments. Despite the fact that the condition is not lethal, it can present itself in a manner that would require a discontinuation of the training. In such cases, it is considered as clinically sev ere. Hanada et al.[2] point out that repeated PAC is quite severe and advices intermittent discontinuation of centrifugal training among subjects who exhibit the condition. Premature ventricular contraction (PVC) The heart’s functions rely on the electrical impulses of the pacemaker.[19] In cases where +Gz forces are introduced into the human anatomy, the said impulses are interfered with. When such interferences occur, the functioning of some of the compartments of the heart is impeded, resulting in a distorted rhythm of heart beat. As an example of cardiac arrhythmia, PVC is characterized by the contraction of the heart’s ventricles before the expected electrical signal. The name ‘premature’ is sourced from this irregular contraction of the ventricles. The diagram below is an ECG representation of this condition: Graph 1: Premature ventricular beats Source: Vettes et al.[6] The study by Hanada et al.[2] points out that PVC can exhibit itself in differen t degrees. There is the occasional premature ventricular contraction, which is a mild version of the condition. Subjects who present the said condition are allowed to continue with centrifugal training owing to the fact that it is not harmful. The harmful case of PVC involves repeated PVC and Bigeminy, Trigeiny PVC. However, in spite of the fact that it is more harmful in comparison to occasional PVC, the latter case calls for the termination of centrifugal training after some time. A look at the study by Hanada et al.[2] reveals that 19 pilots exhibited the paired PVC condition. The number of subjects who presented the condition in subsequent training sessions kept on decreasing. The same indicates that despite being a common occurrence due to centrifugal training, PVC is only severe when a subject is exposed to High G-Stress over a long period of time without a break. A case in point is a pilot who travels in an aircraft at speeds that result in a stress of 5Gz.s-1 without taking a break. Such an individual is likely to experience a severe case of PVC, which might lead to cardiac arrest.[18] Artrial fibrillation Exposure to +Gz requires some form of tolerance from the persons participating in the centrifugal acceleration exercises.[19] Increased exposure and the resultant stresses affect the heart’s electrical functions. The atrial happens to be another region of the heart that is affected by the G-forces. According to Rayman,[1] the +Gz forces can increase the rate at which the pacemaker emits electrical impulses. When this happens, the ventricles contract in an irregular and erratic manner, leading to arterial fibrillation.[20] Whinnery[3] points out that exposure to G stress in such centrifugal exercises is characterized by atrial ectopy. As is the case with the other arrhythmias mentioned in this paper, this condition can be mild or severe depending on levels of exposure. For instance, Vettes et al.[6] suggest that the complication is regarded as normal when subjects are exposed to +2G for about five minutes. However, the researchers point out that the condition becomes severe in cases where the G-force is increased to +5G and the subjects exposed to the same for a period of more than five minute. Conclusion Vettes et al.[6] point out that centrifugal training, and by extension centrifugal acceleration, has a direct impact on cardiac arrhythmia. In the context of this study, centrifugal acceleration is regarded as an avenue of generating G-forces to create stress on human anatomy. Aviation medicine makes use of centrifugal training to effectively understand cardiac arrhythmia. In essence, this condition is caused by the distortion of the normal heart beat. Whinnery[3] introduced the element of human centrifuge in their study. The contraption is used in aviation medicine to conduct experiments on centrifugal acceleration. During such experiments, two main factors determine how G-forces give rise to cardiac arrhythmia. The two include the degree of +Gz and the duration of exposure. Intensity and duration are crucial elements in explaining the various types of arrhythmias. Hanada et al.[2] point out that centrifugal acceleration in centrifugal training exercises gives rise to 3 main types of arrhythmias. The analysis points out that sinus arrhythmia, premature atrial contraction, and premature ventricular contraction are the most common conditions. Atrial fibrillation is another type of arrhythmia associated with the exercises. Each of the conditions above is graded on their severity depending on the magnitude of +Gz. in addition, the duration in which the participants are exposed to the forces adds to the severity of the conditions. As such, it is important to pay attention to the degree of these conditions among individuals taking part in centrifugal training. The aim is to avert cases of cardiac arrest. Such occurrences are fatal, especially when the subjects are exposed to real time flight conditions. References Rayman BR. Clinical aviation medicine.
