Imperfect indifference : the rhythm, structure and politics of neutrality

Cette thèse propose l’émergence d’une poésie de l’entre deux dans la littérature expérimentale, en suivant ses développements du milieu du vingtième siècle jusqu'au début du vingt-et-unième. Cette notion d’entre-deux poétique se fonde sur une théorie du neutre (Barthes, Blanchot) comme ce qui se situe au delà ou entre l'opposition et la médiation. Le premier chapitre retrace le concept de monotonie dans la théorie esthétique depuis la période romantique où il est vu comme l'antithèse de la variabilité ou tension poétique, jusqu’à l’émergence de l’art conceptuel au vingtième siècle où il se déploie sans interruption. Ce chapitre examine alors la relation de la monotonie à la mélancolie à travers l’analyse de « The Anatomy of Monotony », poème de Wallace Stevens tiré du recueil Harmonium et l’œuvre poétique alphabet de Inger Christensen. Le deuxième chapitre aborde la réalisation d’une poésie de l’entre-deux à travers une analyse de quatre œuvres poétiques qui revisitent l’usage de l’index du livre paratextuel: l’index au long poème “A” de Louis Zukofsky, « Index to Shelley's Death » d’Alan Halsey qui apparait à la fin de l’oeuvre The Text of Shelley's Death, Cinema of the Present de Lisa Robertson, et l’oeuvre multimédia Via de Carolyn Bergvall. Le troisième chapitre retrace la politique de neutralité dans la théorie de la traduction. Face à la logique oppositionnelle de l’original contre la traduction, il propose hypothétiquement la réalisation d’une troisième texte ou « l’entre-deux », qui sert aussi à perturber les récits familiers de l’appropriation, l’absorption et l’assimilation qui effacent la différence du sujet de l’écrit. Il examine l’oeuvre hybride Secession with Insecession de Chus Pato et Erin Moure comme un exemple de poésie de l’entre-deux. A la fois pour Maurice Blanchot et Roland Barthes, le neutre représente un troisième terme potentiel qui défie le paradigme de la pensée oppositionnelle. Pour Blanchot, le neutre est la différence amenée au point de l’indifférence et de l’opacité de la transparence tandis que le désire de Barthes pour le neutre est une utopie lyrique qui se situe au-delà des contraintes de but et de marquage. La conclusion examine comment le neutre correspond au conditions de liberté gouvernant le principe de créativité de la poésie comme l’acte de faire sans intention ni raison.

ABNORMAL EXPRESSION OF VOLTAGE-GATED SODIUM CHANNELS Nav1.7, Nav1.3 AND Nav1.8 IN TRIGEMINAL NEURALGIA

Voltage-gated sodium channels have been implicated in acute and chronic neuropathic pain. Among subtypes, Nav1.7 single mutations can cause congenital indifference to pain or chronic neuropathic pain syndromes, including paroxysmal ones. This channel is co-expressed with Nav1.8, which sustains the initial action potential; Nav1.3 is an embrionary channel which is expressed in neurons after injury, as in neuropathic conditions. Few studies are focused on the expression of these molecules in human tissues having chronic pain. Trigeminal neuralgia (TN) is an idiopathic paroxysmal pain treated with sodium channel blockers. The aim of this study was to investigate the expression of Nav1.3, Nav1.7 and Nav1.8 by RT-PCR in patients with TN, compared to controls. The gingival tissue was removed from the correspondent trigeminal area affected. We found that Nav1.7 was downregulated in TN (P=0.017) and Nav1.3 was upregulated in these patients (P=0.043). We propose a physiopathological mechanism for these findings. Besides vascular compression of TN, this disease might be also a channelopathy. (C) 2009 IBRO. Published by Elsevier Ltd.

Beyond neuropathy in hereditary sensory and autonomic neuropathy type V: cognitive evaluation

Background and purpose: Hereditary sensory and autonomic neuropathy ( HSAN) type V is a very rare disorder. It is characterized by the absence of thermal and mechanical pain perception caused by decreased number of small diameter neurons in peripheral nerves. Recent genetic studies have pointed out the aetiological role of nerve growth factor beta, which is also involved in the development of the autonomic nervous system and cholinergic pathways in the brain. HSAN type V is usually reported not to cause mental retardation or cognitive decline. However, a structured assessment of the cognitive pro. le of these patients has never been made. Methods and results: We performed a throughout evaluation of four HSAN type V patients and compared their performance with 37 normal individuals. Our patients showed no cognitive deficits, not even mild ones. Discussion and Conclusions: Although newer mutations on this and related disorders are continuously described, their clinical characterization has been restricted to the peripheral aspects of these conditions. A broader characterization of this rare disorder may contribute to better understand the mechanisms of the nociceptive and cognitive aspects of pain.

Influence of deceleration profiles on occupant velocity differential and injury potential

This paper compares two hypothetical and identical vehicle deceleration profiles mirrored in time, one linearly descending with time and the other linearly ascending with time. The differences of such profiles on occupant velocity differential and by implication, injury levels at the point of occupant impact are presented. An indifference point is established to assist in comparing which occupant body part will benefit from the altered crash pulse. It is shown that for occupant proximity distances below the indifference point, an ascending profile results in lower injury risk. Above the indifference point, the result is reversed.

O paradoxo da cidade monitorada : vigilância limitada e espaços públicos fragilizados a partir do estudo do sistema das câmeras do município de Vila Velha - ES

A dissertação aborda a fragilização dos espaços públicos num contexto de utilização de câmeras de vigilância, temática que será problematizada a partir da vigilância exercida pelas câmeras do município de Vila Velha – ES. Partimos da hipótese de que vivemos cercados por objetos técnicos que continuamente produzem informações sobre os sujeitos sociais e os seus espaços como forma de controle. As câmeras representam o exemplo mais conhecido desses objetos, embora sejam apresentadas pelos discursos das administrações públicas como ferramentas de auxílio à segurança. Utilizando como metodologia a observação participante para acompanhamento do trabalho realizado “por trás” das câmeras, concluímos que uma série de fatores desmistificam esses discursos: as câmeras que não são monitoradas, a ausência de manutenção dos equipamentos do sistema, os baixos salários e as condições trabalhistas daqueles que operam as câmeras, a ausência de articulação com os demais setores da prefeitura, a falta de credibilidade das câmeras com a polícia, etc. Por outro lado, ao fazermos um trabalho “na frente” das câmeras, observando o cotidiano de três áreas vigiadas nos bairros Praia da Costa, Glória e Riviera da Barra, bem como entrevistando transeuntes, moradores e comerciantes, concluímos que a maneira surpreendentemente indiferente com que as pessoas lidam com a vigilância é alimentada quando descobrimos que elas não oferecem a segurança pretendida. Se as câmeras não auxiliam a segurança pública, a sua utilização tem um efeito perverso na fragilização dos espaços públicos de Vila Velha, considerando que a vigilância representa ameaças potenciais e reais às condições que o pressupõem: a pluralidade e a liberdade, pois as câmeras atualizam um estado de vigilância permanente alimentando o estigma sobre determinados grupos sociais, que, por sua vez, são os alvos favoritos da vigilância, o que permite às câmeras, ainda, a potencial função de controle socioespacial direto (função admitida inclusive pelos cidadãos entrevistados) sobre os espaços vigiados; e a individualidade dos cidadãos, que é acintosamente violada. As câmeras, portanto, ao pretenderem garantir qualidade de vida à população (oferecendo segurança), produzem o efeito exatamente inverso

Twin Peaks como alegoria daimónica cinematográfica

For a long time the allegorical activity was considered dogmatic and equated with artistic fossilization, archaic religious propensity and lack of creativity. However, Walter Benjamin (1928) and Paul De Man (1969), among other illustrious thinkers, came to its defense, exalting, instead, its cryptic, hybrid and abstract nature, which, incidentally, are the main characteristics of modern art. “Twin Peaks – Fire Walk with Me” (David Lynch, 1992) is a wonderful object of analysis, despite being one of the most misunderstood films in the history of cinema. The fact that its narrative is a prequel to the cult television series “Twin Peaks” and incorporates many of the characters of that show, explicitly denigrating the moral image of the protagonist, Laura Palmer, brought about an intense rejection by the fans of the series, as well as the indifference of the cinephilic community in general. However, one must go deeper, in order to understand Lynch’s brave accomplishment and its artfulness. Indeed, the opus is a powerful cinematic allegory because it contains a double layer of metaphorical meaning, one of them being explicitly metacinematic. Thus, besides assuming itself as a filmic daimonic allegory, occurring in a spiritual universe of Good versus Evil, the film is also an authorial discourse on cinema itself. More specifically, it is an allegory of spectatorship, according to Robert Stam’s definition, where the existence and crossing over to “another side” duplicates the architecture of movie theatres and the psychic processes involved in film viewing.

Bullying escolar – Intervenientes, ações e sentimentos associados: um estudo com alunos do 2º e 3º ciclos da região do Algarve

Introdução – O bullying pode ser definido como atitudes agressivas, intencionais e repetidas durante um período de tempo. Diversos estudos verificaram a prevalência de bullying entre estudantes de vários países e demonstraram que este é um problema internacional e que pelo menos um em cada dez estudantes está envolvido numa situação de bullying. Objetivos – Caracterizar as situações de bullying no ambiente escolar, o papel do estudante, os sentimentos associados a essas ações e identificar as características do agressor. Métodos – A amostra foi constituída por 519 alunos matriculados em duas escolas da região sul de Portugal que preencheram um questionário anónimo sobre uma situação de bullying que vivenciaram, descrevendo o papel do aluno e o que sentiram nesta situação. Resultados – Os resultados revelaram que em 61,7% dos casos se tratou de agressão física e 29,7% de agressão verbal. Desempenharam o papel de agressores 12,7% dos alunos, 21,8% foram vítimas e 63,6% foram testemunhas desta situação. 10,6% dos alunos relataram sentir bem, 11% mostraram indiferença e 78,4% dos alunos sentiram‑se mal com a situação de bullying. Verificou‑se que, com o avanço da idade, o estudante aumentava em 1,5 vezes a probabilidade de desempenhar o papel de agressor e os rapazes apresentavam 5,2 vezes mais probabilidades de vir a ser agressor numa situação de bullying. Conclusão – O presente estudo verificou que a maioria dos alunos participou de uma situação de bullying escolar como testemunha, sendo os casos mais comuns de agressão física. A maioria dos alunos sentiu‑se mal com essa situação. Os rapazes e os alunos com mais idade tiveram mais probabilidade de vir a desempenhar o papel de agressor numa situação de bullying.

¿La edad de la política? Balanche Historiográfico de los estudios sobre comunicación e información política en la sociedad ibérica moderna

Los estudios sobre política y su impacto y circulación entre la sociedad moderna, han solido limitar su expansión a un número reducido de personas del entorno más próximo a los grandes actores cortesanos frente a la tradicional “indiferencia” del común. Sin embargo, gracias a la renovación de la historiografía de lo político y a su interés por áreas culturales y sociales ajenas a su tradicional consideración, en las últimas décadas se ha descubierto un interesante terreno de experiencias políticas que nos puede servir como atalaya para conocer la difusión de la información sobre los hechos políticos también entre “gente corriente”. A nuestro juicio, es un momento adecuado para evaluar el desarrollo de un fenómeno historiográfico carente de cierta sistematicidad, razón por la que planteamos este balance crítico y analítico sobre la sociedad ibérica del Antiguo Régimen.

Investigações sobre doenças de Psittacideos

The present paper colligates the notions acquired in previous investigations, already published, and new observations upon diseases of the psittacidae, liable to be confused with psittacosis of parrots. The author calls attention to the indifference with regard to this question shown by investigators, even by those who dealt with the study of this disease on the occasion of the latest outbreak of psittacosis, in flagrant contrast with the researches upon the alterations induced by pathogenic agents of other diseases transmissible to man, when these agents pass through animals or when the latter are depositaries of the virus. This remark considerably enhances the importance of the presence paper from a hygienic and epidemiologic point of view, representing moreover a contribution to general knowledge and to veterinary medicine. The researches carried out since the appearance of the latest outbreak of psittacosis,-which occurred simultaneously with an epizooty in parrots lodged in aviary of the park of Agua Branca (Directory of Animal Industry of the State São Paulo)-led to the verification of the frequent existence in these animals of various diseases liable to be confused with psittacosis. These diseases are due to two kinds of pathogenic agents: virus and bacteria. In the first group there are to be found the diseases occasioned by the virus of human psittacosis, discovered by Western, Bedson and Simpson, and the disease me with in parrots coming from traders in S. Paulo. The infections by bacteria of the genus Salmonella and by those of other genera belong to the second group. As differential characters of the two infections due to virus, delineated on the strength of notions drawn from a detailed experimental study and from the literature on this subject, the following are given: ¹ Samples of our virus were sent, for comparison, to various investigators of psittacosis. Amongst them, Prof. M. Rivers acceded to our request; he found its nature to be different from that of the virus of psittacosis studiedby him. We are very much obliged to him for the attention he paid to this verification. Virus of psittacosis - Infectiousness: man, monkey, rabbit, mouse, hen, canary. Neurotropic affinity. Inclusions: small, protoplasmic. Exsiccation: the virus has good power of preservation. Symptoms: inactivity, drowsiness, frequent diarrhoea, oculo-nasal discharge and cough, coma. Duration: 4 to 5 days. Bodily lesions: congestion of intestines, splenomegaly. Virus of S. Paulo - Infects only psittacidae, particularly those of the genus Amazona. No localization in the nervous system. Large, nuclear. Is rapidly destroyed. Inactivity, inappetency, adynamia (drooping of the wings, indifference, leaning its beak against the bars of the cage in order not to fall down); profuse diarrhoea, of whitish stools, at times enterorrhagia; prolonged coma. 2 to 8 days. Foci of yellowish necrosis in liver, spleen and lung. At times, congestion of intestines. Characteristic features common to the two viruses.-They act in great dilutions, filter through tight candles though being partly retained, are preserved under glycerine or Bedson's solution, are stable at 55°C. heat and are destroyed by physical and chemical agents. Both virus diseases are very seldom met with in psittacidae: only once, amongst numberless sick parrots, the author met with a disease of the virus differring from that of psittacosis. This disease, greatly transmissible to man, ought to be more frequent, if it were common in parrots. On the contrary, bacteria cause diseases in these animals with great frequency, presenting variable characters, from a severe epizootic form, rapidly mortal, to ambulatory or silent forms, for the most part developing towards a cure or assuming a chronic character. Amongst the bacteria which cause the infection of this group the salmonellae predominate and amongst them the bacterium discovered by Nocard, as well as a species which in the course of this study is characterized under the name of Salmonella nocardi. The author believes that in the epizooty from which Nocard isolated his bacterium there was association of the virus-disease inducing the epizooty of that epoch in Paris with the bacterial disease, as must have happened in Argentina, where the disease was transmitted to man, and Santillan, according to Barros, isolated from the sick parrots bacteria of the genus Salmonella. The diseases of the two groups, that due to virus and that due to bacteria, are differentiated: Virus-diseases - Evolution: rapid, nearly always followed by death. Symptoms: sadness, profuse diarrhoea, of whitish stools, at times enterorrhagia, complete inappetency, adynamia, indifference, prolonged coma. Clinical forms: acute and subacute. Lesions: Foci of necrosis in liver and spleen without cellular reaction around the focus, yellow liver, multiple serositis. Presence of protoplasmic or nuclear granulations. Bacteriology: Complete lack or inconstant presence of bacteria in the organs and blood. Infectiousness of the organs and blood after filtration: positive. Bacterial diseases - Varies from one week to a month or more, not always fatal. Sadness, partial inappetency, tremblings, intensive thirst, mucous or mucosanguineous diarrhoea, lack of adynamia (reacts to stimulations and moves well at any time of the disease, though showing little disposition to locomotion), soiling of feathers. Frustrate, acute, subacute and chronic. Hepatic and intestinal cogestion, foci of necrosis in liver, spleen and lung with cellular reaction around the focus. Lack of granulations. Constant presence of bacteria in the organs and blood. Negative. The analysis of the litterature shows that the characteristic features of the diseases in parrots referred to parrot psittacosis, more frequently approach the bacterial diseases here described of these animals, a hypothesis which is reinforced by the observation of the greater frequency of infections...

Choice, Deferral and Consistency

In this paper we study decision making in situations where the individual’s preferences are not assumed to be complete. First, we identify conditions that are necessary and sufficient for choice behavior in general domains to be consistent with maximization of a possibly incomplete preference relation. In this model of maximally dominant choice, the agent defers/avoids choosing at those and only those menus where a most preferred option does not exist. This allows for simple explanations of conflict-induced deferral and choice overload. It also suggests a criterion for distinguishing between indifference and incomparability based on observable data. A simple extension of this model also incorporates decision costs and provides a theoretical framework that is compatible with the experimental design that we propose to elicit possibly incomplete preferences in the lab. The design builds on the introduction of monetary costs that induce choice of a most preferred feasible option if one exists and deferral otherwise. Based on this design we found evidence suggesting that a quarter of the subjects in our study had incomplete preferences, and that these made significantly more consistent choices than a group of subjects who were forced to choose. The latter effect, however, is mitigated once data on indifferences are accounted for.

Nondictatorial Arrovian Social Welfare Functions: An Integer Programming Approach

In the line opened by Kalai and Muller (1997), we explore new conditions on prefernce domains which make it possible to avoid Arrow's impossibility result. In our main theorem, we provide a complete characterization of the domains admitting nondictorial Arrovian social welfare functions with ties (i.e. including indifference in the range) by introducing a notion of strict decomposability. In the proof, we use integer programming tools, following an approach first applied to social choice theory by Sethuraman, Teo and Vohra ((2003), (2006)). In order to obtain a representation of Arrovian social welfare functions whose range can include indifference, we generalize Sethuraman et al.'s work and specify integer programs in which variables are allowed to assume values in the set {0, 1/2, 1}: indeed, we show that, there exists a one-to-one correspondence between solutions of an integer program defined on this set and the set of all Arrovian social welfare functions - without restrictions on the range.

Emotional behavior in acute stroke: the Lausanne emotion in stroke study.

OBJECTIVE: To study emotional behaviors in an acute stroke population. BACKGROUND: Alterations in emotional behavior after stroke have been recently recognized, but little attention has been paid to these changes in the very acute phase of stroke. METHODS: Adult patients presenting with acute stroke were prospectively recruited and studied. We validated the Emotional Behavior Index (EBI), a 38-item scale designed to evaluate behavioral aspects of sadness, aggressiveness, disinhibition, adaptation, passivity, indifference, and denial. Clinical, historical, and imaging (computed tomography/magnetic resonance imaging) data were obtained on each subject through our Stroke Registry. Statistical analysis was performed with both univariate and multivariate tests. RESULTS: Of the 254 patients, 40% showed sadness, 49% passivity, 17% aggressiveness, 53% indifference, 76% disinhibition, 18% lack of adaptation, and 44% denial reactions. Several significant correlations were identified. Sadness was correlated with a personal history of alcohol abuse (r = P < 0.037), female gender (r = P < 0.028), and hemorrhagic nature of the stroke (r = P < 0.063). Aggressiveness was correlated with a personal history of depression (r = P < 0.046) and hemorrhage (r = P < 0.06). Denial was correlated with male gender (r = P < 0.035) and hemorrhagic lesions (r = P < 0.05). Emotional behavior did not correlate with either neurologic impairment or lesion localization, but there was an association between hemorrhage and aggressive behavior (P < 0.001), lack of adaptation (r = P < 0.015), indifference (r = P < 0.018), and denial (r = P < 0.045). CONCLUSIONS: Systematic observations of acute emotional behaviors after stroke suggest that emotional alterations are independent of mood and physical status and should be considered as a separate consequence of stroke.
