Is The Burden of Medical Education Affecting Ethics of Medical Treatment?

A substantial number of medical students in India have to bear an enormous financial burden for earning a bachelor's degree in medicine referred to as MBBS (bachelor of medicine and bachelor of surgery). This degree program lasts for four and one-half years followed by one year of internship. A postgraduate degree, such as MD, has to be pursued separately on completion of a MBBS. Every medical college in India is part of a hospital where the medical students get clinical exposure during the course of their study. All or at least a number of medical colleges in a given state are affiliated to a university that mainly plays a role of an overseeing authority. The medical colleges usually have no official interaction with other disciplines of education such as science and engineering, perhaps because of their independent location and absence of emphasis on medical research. However, many of the medical colleges are adept in imparting high-quality and sound training in medical practices including diagnostics and treatment. The medical colleges in India are generally of two types, i.e., government owned and private. Since only a limited number of seats are available across India in the former category of colleges, only a small fraction of aspiring candidates can find admission in these colleges after performing competitively in the relevant entrance tests. A major advantage of studying in these colleges is the nominal tuition fees that have to be paid. On the other hand, a large majority of would-be medical graduates have to seek admission in the privately run medical institutes in which the tuition and other related fees can be mind boggling when compared to their public counterparts. Except for candidates of exceptionally affluent background, the only alternative for fulfilling the dream of becoming a doctor is by financing one's study through hefty bank loans that may take years to pay back. It is often heard from patients that they are asked by doctors to undergo a plethora of diagnostic tests for apparently minor illnesses, which may financially benefit those prescribing the tests. The present paper attempts to throw light on the extent of disparity in cost of a medical education between state-funded and privately managed medical colleges in India; the average salary of a new medical graduate, which is often ridiculously low when compared to what is offered in entry-level engineering and business jobs; and the possible repercussions of this apparently unjust economic situation regarding the exploitation of patients.

Relaxor ferroelectricity and electric-field-driven structural transformation in the giant lead-free piezoelectric (Ba,Ca)(Ti, Zr)O-3

There is great interest in lead-free (Ba0.85Ca0.15)(Ti0.90Zr0.10)O-3 (15/10BCTZ) because of its exceptionally large piezoelectric response Liu and Ren, Phys. Rev. Lett. 103, 257602 (2009)]. In this paper, we have analyzed the nature of: (i) crystallographic phase coexistence at room temperature, (ii) temperature-and field-induced phase transformation to throw light on the atomistic mechanisms associated with the large piezoelectric response of this system. A detailed temperature-dependent dielectric and lattice thermal expansion study proved that the system exhibits a weak dielectric relaxation, characteristic of a relaxor ferroelectric material on the verge of exhibiting a normal ferroelectric-paraelectric transformation. Careful structural analysis revealed that a ferroelectric state at room temperature is composed of three phase coexistences, tetragonal (P4mm)+ orthorhombic (Amm2) + rhombohedral (R3m). We also demonstrate that the giant piezoresponse is associated with a significant fraction of the tetragonal phase transforming to rhombohedral. It is argued that the polar nanoregions associated with relaxor ferroelectricity amplify the piezoresponse by providing an additional degree of intrinsic structural inhomogeneity to the system.

Las bodas de Camacho y una relectura del mito de D. Quijote desde versiones operísticas del episodio cervantino

Resumen: El mundo de la ópera es un campo de permanentes ebulliciones aunque todavía se le endilguen acusaciones falsas de inmovilidad y anquilosamiento. No cesan de componerse obras con lenguajes innovadores sobre temáticas inéditas. Se experimenta —a veces, abusivamente— con puestas en escena heterodoxas, y las investigaciones hallan partituras perdidas o relegadas que hacen variar, permanentemente, el mapa del canon del género. En el presente trabajo, se analiza un caso-testigo de estas continuas mutaciones. Es la recuperación entre 2006 y 2011 de tres óperas compuestas entre 1760 y 1830 sobre el episodio del Quijote referido a las bodas de Camacho. Reviste particular relevancia, a mi juicio, porque no solo ha aumentado el caudal del repertorio operístico conocido sino que por sus relaciones con la literatura nos alerta a los estudiosos de ésta acerca de fenómenos que no podemos dejar de considerar. Ellos atañen a la recepción de la obra cervantina y al mito de D. Quijote, mito cuya expansión sobrepasa, ampliamente, al público lector de la obra. Nos conduce, por lo tanto, más allá de lo literario, a las complejidades de la construcción del imaginario cultural.

Films de polietileno oxo-degradados mediante envejecimiento acelerado por radiación UV y calor

Resumen: Los materiales plásticos utilizados en la industria del embalaje y transporte de mercaderías familiares e industriales, presentan numerosas ventajas que los han puesto en su lugar durante los últimos 50 años. En la actualidad, son miles de millones de toneladas anuales de bolsas o embalajes de polietileno, las que diariamente se producen, se usan, se recuperan (en muy pequeña parte) y son finalmente dispuestas, quemadas o literalmente arrojadas al medio ambiente. La alta estabilidad química o la muy baja tasa de degradación, hace que estos residuos perduren en el medio - en la mayoría de los casos por más de 100 años- dependiendo las condiciones ambientales locales. Hace pocos años, se adaptaron conocimientos científicos a esta problemática, y de ello nacieron dos formas de atacar la eliminación del plástico como desecho (más allá del reciclado y uso racional): por un lado, la utilización de bioplásticos con propiedades biodegradables; y por otro, el agregado de aditivos pro-degradantes a plásticos convencionales. El presente trabajo, tiene por objeto tomar a esta última herramienta, sobre la cual se han comenzado a estudiar los mecanismos químicos por los cuales cumplen su función, evaluándolos en distintas condiciones aceleradas de laboratorio. De esta manera, se caracterizaron velocidades de degradación abiótica mediante envejecimientos acelerados con radiación ultravioleta y térmica, para films de polietileno aditivados con un compuesto oxodegradante comercial. Se estudiaron distintas concentraciones de aditivo en el polímero, en función del tiempo de envejecimiento. Las caracterizaciones incluyeron análisis mecánico, análisis térmico diferencial, espectroscopía de absorción infrarroja y de Absorción Atómica.

De Jiménez de Asúa a Perón : sus exilios como componentes de la política exterior hispano-argentina

Resumen: El compromiso vital de Jiménez de Asúa con sus ideas y con la España republicana, lanzará al eminente jurista al exilio en la Argentina, donde su prestigio intelectual le permitirá retomar su vida académica. Al encarnar la oposición legal en el exterior contra el solidificado régimen franquista, colocará su protagonismo en una situación cercana al poder desestabilizador del exilio en España del mismo Perón. La política exterior de la Argentina y de España, por diferentes vías de intervención, pero sin definiciones drásticas, procurará influir indirectamente para neutralizar a ambos.

Topics in quantum gravity

We study some aspects of conformal field theory, wormhole physics and two-dimensional random surfaces. Inspite of being rather different, these topics serve as examples of the issues that are involved, both at high and low energy scales, in formulating a quantum theory of gravity. In conformal field theory we show that fusion and braiding properties can be used to determine the operator product coefficients of the non-diagonal Wess-Zumino-Witten models. In wormhole physics we show how Coleman's proposed probability distribution would result in wormholes determining the value of ^θQCD. We attempt such a calculation and find the most probable value of ^θQCD to be π. This hints at a potential conflict with nature. In random surfaces we explore the behaviour of conformal field theories coupled to gravity and calculate some partition functions and correlation functions. Our results throw some light on the transition that is believed to occur when the central charge of the matter theory gets larger than one.

Vegetation Effects on Fish Distribution in Impounded Salt Marshes

We compared the density and biomass of resident fish in vegetated and unvegetated flooded habitats of impounded salt marshes in the northern Indian River Lagoon (IRL) Estuary of east-central Florida. A 1-m2 throw trap was used to sample fish in randomly located, paired sample plots (n = 198 pairs) over 5 seasons in 7 impoundments. We collected a total of 15 fish taxa, and 88% of the fishes we identified from the samples belonged to three species: Cyprinodon variegatus (Sheepshead Minnow), Gambusia holbrooki (Eastern Mosquitofish), and Poecilia latipinna (Sailfin Molly). Vegetated habitat usually had higher density and biomass of fish. Mean fish density (and 95% confidence interval) for vegetated and unvegetated sites were 8.2 (6.7–9.9) and 2.0 (1.6–2.4) individuals m-2, respectively; mean biomass (and 95% confidence interval) for vegetated and unvegetated sites were 3.0 (2.5–3.7) and 1.1 (0.9–1.4) g m-2, respectively. We confirmed previous findings that impounded salt marshes of the northern IRL Estuary produce a high standing stock of resident fishes. Seasonal patterns of abundance were consistent with fish moving between vegetated and unvegetated habitat as water levels changed in the estuary. Differences in density, mean size, and species composition of resident fishes between vegetated and unvegetated habitats have important implications for movement of biomass and nutrients out of salt marsh by piscivores (e.g., wading birds and fishes) via a trophic relay.

Keep an "eye" on the text: The Use of Self-mention in the Academic Writing of Experts

One of the most controversial inquiries in academic writing is whether it is admissible to use first person pronouns in a scientific paper or not. Many professors discourage their students from using them, rather favoring a more passive tone, and thus causing novices to avoid inserting themselves into their texts in an expert-like manner. Abundant research, however, has recently attested that negotiation of identity is plausible in academic prose, and there is no need for a paper to be void of an authorial identity. Because in the course of the English Studies Degree we have received opposing prompts in the use of I, the aim of this dissertation is to throw some light upon this vexed issue. To this end, I compiled a corpus of 16 Research Articles (RAs) that comprises two sub-corpora, one featuring Linguistics RAs and the other one Literature RAs, and each, in turn, consists of articles written by American and British authors. I then searched for real occurrences of I, me, my, mine, we, us, our and ours, and studied their frequency, rhetorical functions and distribution along each paper. The results obtained certainly show that academic writing is no longer the faceless prose that it used to be, for I is highly used in both disciplines and varieties of English. Concerning functions, the most typically used roles were the use of I to take credit for the writer’s research process, and also those involving plural forms. With respect to the spatial disposition, all sections welcomed first person pronouns, but the Method and the Results/Discussion sections seem to stimulate their appearance. On the basis of these findings, I suggest that an L2 writing pedagogy that is mindful not only of the language proficiency, but also of the students’ own identity may have a beneficial effect on the composition of their texts.

Possíveis relações entre a área de pesca, profundidade e tempo de imersão nas actividades da pesca com covos

A cruise aboard the vessel Cassiopeia was held from 14 to 22 November 2000. The objective to map the fishing areas, to study the variation of the catch, income, specific composition and length on wishbone Polysteganus coeruleopunctatus (cachucho) in relation to fishing areas, depth and immersion time of the fish pots. The total capture registered was 4.350,00 Kg for 1600 fish pots and 32 effectuated throws. The highest capture per throw was registered in the interval of depth between the 140 to 180 meters. Regarding the time of immersion, the better captures were obtained in the interval between 25 and 30 hours. The profits during this cross were for fish-trap (2, 71 kg), per throw 135,00 Kg and for immersion hour 6,07 kg. P. coeruleopunctatus (cachucho) was more abundant in number in Quissico, while in Zavora it was abundant in number and also in weight. Likewise, the cachucho was more abundant in number and weight in the captures of the fish pots submerged less than 24 hours, 100-140 meters depth. Cachucho catch under 100 meters depth was quite reduced (less than 1 %). The middle length of the cachucho captured during the cross was 275,7 mm. There were significant differences in the lengths of the cachucho accordingly to depth or fishing area. The smallest individual (fish) was captured by fish pots that were submerged more than 24 hours. The principal recommendations of the study refer to maintenance of the current fishing effort with regard to the number of fish pots, and explore the fishing areas on a rotating basis, to avoid the local effort, currently high.

Fingidores em cena: a metaficção em Sérgio SantAnna e Rubens Figueiredo

A partir de uma proposta de ampliação do conceito de metaficção, a tese tem como objetivo investigar os usos metaficcionais nas obras de dois autores da literatura brasileira contemporânea: Sérgio SantAnna e Rubens Figueiredo. No caso de Sérgio SantAnna, são investigadas as relações que a metaficção estabelece com o controle do imaginário, com a reflexão estética feita no interior dos textos ficcionais e com a polêmica em torno das vanguardas. No caso de Rubens Figueiredo, a discussão sobre o uso do discurso metaficcional levará em conta os três ciclos pelos quais passa a obra do autor, ciclos esses marcados pela ênfase em determinadas questões, tais como a parodização de romances policiais, a questão da identidade e a problemática do social. O olhar panorâmico lançado para a obra ficcional dos dois autores deverá mostrar como os diferentes usos metaficcionais − ao atribuírem valores diferenciados à ligação que a literatura tem com o chamado mundo real − sinalizam duas concepções quase antagônicas do fenômeno literário

Blogs de Educadores: perspectivas inovadoras na formação continuada de professores?

O presente trabalho discute as perspectivas para a formação de professores presentes nos blogs de educadores, que buscam e transmitem conhecimentos, em uma rede colaborativa que desponta como uma nova modalidade de formação continuada. Optou-se pela abordagem metodológica qualitativa, dada as características do objeto de estudo e pela possibilidade de ampliação do diálogo entre a teorização e os dados coletados. Procedeu-se uma discursão a partir do discurso dos professores blogueiros entrevistados e da observação de seus blogs. Os 31 blogs que se teve acesso foram classificados segundo suas características preponderantes. Responderam o questionário proposto 27 blogueiros. Pode-se afirmar que os blogs dados seus aspectos de ferramentas de interação, de fácil acesso e uso e de aglutinação de pessoas em razão de interesses comuns, têm efeitos sobre a prática docente. Embora se tenha identificado nos blogs a prevalência de uma concepção compensatória, eles se mostram como ações de autogerenciamento por parte dos docentes, que não mais se isolam com suas dúvidas, incertezas e insegurança, mas, valendo-se da democratização da informática, lançam-se na internet para socializar saberes, partilhar práticas em uma rede de colaboração mútua.

Etymological notes on Aleut (III). With methodological notes on (Eskimo-Aleut) historical linguistics

[EN] The goal of this contribution is twofold: on the one hand, to review two relatively recent contributions in the field of Eskimo-Aleut historical linguistics in which it is proposed that Eskimo-Aleut languages are related genealogically to Wakashan (Holst 2004) and?/or Nostratic (Krougly-Enke 2008). These contributions can be characterized by saying that their authors have taken little care to be diligent and responsible in the application of the comparative method, and that their familiarity with the languages involved is insufficient. Eskimo-Aleut languages belong to a very exclusive group of language families that have been (and still are) used, sometimes compulsively, in the business of so-called “long-range comparisons”. Those carrying out such studies are very often unaware of the most basic facts regarding the philological and linguistic traditions of those languages, as a result of what mountains of very low quality works with almost no-relevancy for the specialist grow every year to the desperation of the scientific community, whose attitude toward them ranges from the most profound indifference to the toughest (and most explicit) critical tone. Since Basque also belongs to this group of “compare-with-everything-you-come- across” languages, it is my intention to provide the Basque readership with a sort of “pedagogical case” to show that little known languages, far from underrepresented in the field, already have a very long tradition in historical and comparative linguistics, i.e. nobody can approach them without previous acquaintance with the materials. Studies dealing with the methodological inappropriateness of the Moscow School’s Nostratic hypothesis or the incorrectness of many of the proposed new taxonomic Amerindian subfamilies (several of them involving the aforementioned Wakashan languages), that is to say, the frameworks on which Krougly-Enke and Holst work, respectively, are plenty (i.a. Campbell 1997: 260-329, Campbell & Poser 2008: 234-96), therefore there is no reason to insist once more on the very same point. This is the reason why I will not discuss per se Eskimo-Aleut–Wakashan or Eskimo-Aleut–Nostratic. On the contrary, I will focus attention upon very concrete aspects of Krougly-Enke and Holst´s proposals, i.e. when they work on “less ambitious” problems, for example, dealing with the minutiae of internal facts or analyzing certain words from the sole perspective of Eskimo-Aleut materials (in other words, those cases in which even they do not invoke the ad hoc help of Nostratic stuff). I will try to explain why some of their proposals are wrong, demonstrate where the problem lies, and fix it if possible. In doing so, I will propose new etymologies in an attempt at showing how we may proceed. The main difference between this and handbook examples lies in the reality of what we are doing: this is a pure etymological exercise from beginning to end. I will try to throw a bit of light on a couple of problematic questions regarding Aleut historical phonology, demonstrating how much work should be done at the lowest level of the Eskimo-Aleut pyramid; it is technically impossible to reach the peak of the pyramid without having completed the base. As far as Aleut is regarded, I will mainly profit not only from the use of the traditional philological analysis of Aleut (and, eventually, of Eskimo) materials, but also of diachronic typology, bringing into discussion what in my opinion seems useful, and in some cases I think decisive, parallels. It is worth noting that this paper makes up yet another part of a series of exploratory works dealing with etymological aspects of the reconstruction of Proto-Eskimo-Aleut, with special emphasis on Aleut (vid. i.a. Alonso de la Fuente 2006/2007, 2008a, 2008b, 2010a), whose main goal is to become the solid basis for an etymological dictionary of the Aleut language, currently in progress.

A sede do deserto: Lavoura arcaica e a parábola do pródigo

Desde que foi publicado, em 1975, Lavoura arcaica vem intrigando os leitores com a sua dessemelhança. Em meio a livros que absorviam a violência do regime militar brasileiro, Raduan Nassar surgiu com uma obra estranha, que se nutria de uma linguagem poética profundamente ressonante, do pensamento monoteísta mediterrâneo, da herança cultural árabe, da subversão pela via da sexualidade. O tempo passou, o escritor abandonou a literatura, muita coisa interessante foi dita sobre o romance, mas seus enigmas são ainda sementes lançadas em solo fértil. Lavoura arcaica é mais uma releitura da prolífica parábola do filho pródigo, presente no Evangelho de Lucas e reelaborada inúmeras vezes ao longo dos seus dois mil anos de existência. A história do jovem rebelde que decide romper os laços com a família para se lançar no mundo tem se mostrado generosa para com a imaginação de muitos autores, que se dispuseram a reescrevê-la com o filtro de suas óticas particulares. Alguns deles estão no presente trabalho: Gide, Kipling, Kafka, Rilke, Dalton Trevisan, Lúcio Cardoso e também o teólogo católico Henri Nouwen. Apesar das variações, a volta para casa ocupa em todas as narrativas um lugar privilegiado. Essa é uma história, afinal, sobre os motivos que levam o sujeito a ir embora e, mais ainda, sobre as razões que fazem com que regresse. Arrependimento, recomeço, fraqueza, derrota, amor? A despeito das muitas antíteses que encontramos no texto de Raduan, elas não exigem que façamos uma escolha entre o arcaico e o moderno, entre ficar ou partir, entre o individual e o coletivo, entre a contenção e a entrega. Essa é a questão: Lavoura arcaica não é um livro sobre a luta do bem contra o mal, da liberdade contra a opressão, mas um painel que mostra como tudo isso se mistura na mesma paisagem ou, parafraseando o personagem André, como as coisas só se unem se desunindo
