The taxonomy of Brazilian insects vectors of transmissible diseases (1900-2000) - then and now

A brief historical overview is given of the most relevant taxonomic studies of insect groups vectors of transmissible diseases in Brazil, from the "heroic" times of the foundation of the Instituto Oswaldo Cruz in Rio de Janeiro up to the present. The following orders are considered: Phthiraptera (Anoplura, Amblycera and Ischnocera), Hemiptera (Reduviidae: Triatominae), Siphonaptera and Diptera (Culicidae, Ceratopogonidae, Psychodidae: Phlebotominae, Simuliidae, Tabanidae, Chloropidae and Muscidae). The most important Brazilian collections of each group are cited.

Sobre la dificultad de ser nihilista

Este artículo ofrece un análisis del nihilismo de Nietzsche y su distinción entre nihilismo activo y pasivo, y propone que cada uno de ellos ha dado lugar a una línea distinta de filosofía de la cultura. El artículo concluye con una reflexión sobre la dificultad de ser nihilista.

Perdida toda coherencia: El Descubrimiento de América en la 'crisis de la conciencia europea'

Este trabajo estudia de qué modo el Descubrimiento del Nuevo Mundo contribuyó no sólo a la descomposición del Viejo Mundo, sino, más aún, a la desaparición del"mundo" o"cosmos" mismo, entendido como un todo definido y ordenado jerárquicamente según valores trascendentes. ABSTRACT: This paper studies how the Discovery of the New World contributed not only to the decomposition of the Old World, but moreover to the disappearance of the"world" or"cosmos" itself, understood as a whole defined and ordered hierarchically according to trascendent values

Intravitreal chemotherapy for vitreous seeding in retinoblastoma: Recent advances and perspectives.

For decades intravitreal chemotherapy (IViC) remained virtually banished from the therapeutic armamentarium against retinoblastoma, except as a heroic attempt of salvage before enucleation in only eyes with refractory vitreous seeding. Very recently, we have initiated a reappraisal of this route of administration by (1) profiling eligibility criteria, (2) describing a safety-enhanced injection procedure, (3) adjusting the tumoricidal dose of melphalan, and (4) reporting an unprecedented efficacy in terms of tumor control of vitreous seeding. Since then, intravitreal chemotherapy is being progressively implemented worldwide with great success, but still awaits formal validation by the ongoing prospective phase II clinical trial. As far as preliminary results are concerned, IViC appears to achieve complete vitreous response in 100% of the 35 newly recruited patients irrespective of the previous treatment regimen, including external beam radiotherapy and/or intra-arterial melphalan. In other words, vitreous seeding, still considered as the major cause of primary and secondary enucleation, can now be controlled by IViC. However, sterilization of vitreous seeding does not necessarily translate into eye survival, unless the retinal source of the seeds receives concomitant therapy. In conclusion, IViC, an unsophisticated and cost-effective treatment, is about to revolutionize the eye survival prognosis of vitreous disease in advanced retinoblastoma.

Hyperkalemia. A prognostic factor during acute severe hypothermia.

When hypothermic patients appear to be dead, the decision to resuscitate may be difficult due to lack of reliable criteria of death. To discover useful prognostic indicators, we reviewed the hospital charts of nine hypothermic victims of snow avalanches (group A: median value of rectal temperature, 29.6 degrees C; range, less than 12 degrees C to 34 degrees C) and of 15 patients with hypothermia following acute drug intoxication and/or cold exposure (group B: 28.8 degrees C; range, 25.5 degrees C to 32 degrees C. In group A, plasma potassium level on admission was extremely high (14.5 mmol/L; range, 6.8 to 24.5 mmol/L) compared with that obtained in group B (3.5 mmol/L; range, 2.7 to 5.3 mmol/L). All patients in group A were in cardiorespiratory arrest. None could be successfully resuscitated despite effective rewarming by cardiopulmonary bypass or peritoneal lavage. In contrast, all of the patients in group B recovered from hypothermia, including two in cardiorespiratory arrest. Thus, extreme hyperkalemia during acute hypothermia appears to be a reliable marker of death. It might be used to select those patients in whom heroic resuscitation efforts can be useful.

Ilustración y nihilismo en los Artículos de Mariano José de Larra

En la primera parte de este artículo se muestra cómo el concepto de ser humano que Larra utiliza en sus escritos es de clara raigambre ilustrada. En la segunda, se analiza cómo el autor de los Artículos, tras tomar conciencia de los límites de dicho ideal, reaccionó con un extremismo nihilista que le llevó a ver como detestables aquellas capacidades humanas que los ilustrados habían valorado positivamente: el lenguaje, la racionalidad y la sociabilidad. En la tercera parte, se estudia, a la luz de los escritos de Friedrich Nietzsche, los dos tipos de nihilismo que se enfrentaron en el espíritu y en la obra de Larra.

Sublimidad y nihilismo en la cultura del barroco

Este trabajo estudia el concepto de"lo sublime" en la cultura barroca, con el objetivo de demostrar que, aunque no fue teorizado sistemáticamente hasta el siglo XVIII, este cobró durante el siglo XVII una centralidad y, sobre todo, un significado filosófico semejantes a los que se impondrían posteriormente y que, según veremos, está estrechamente ligado con el concepto de"nihilismo".

Playing to Learn: Business Simulation Games as Leadership Learning Environments

The aim of this dissertation is to investigate if participation in business simulation gaming sessions can make different leadership styles visible and provide students with experiences beneficial for the development of leadership skills. Particularly, the focus is to describe the development of leadership styles when leading virtual teams in computer-­supported collaborative game settings and to identify the outcomes of using computer simulation games as leadership training tools. To answer to the objectives of the study, three empirical experiments were conducted to explore if participation in business simulation gaming sessions (Study I and II), which integrate face-­to-­face and virtual communication (Study III and IV), can make different leadership styles visible and provide students with experiences beneficial for the development of leadership skills. In the first experiment, a group of multicultural graduate business students (N=41) participated in gaming sessions with a computerized business simulation game (Study III). In the second experiment, a group of graduate students (N=9) participated in the training with a ‘real estate’ computer game (Study I and II). In the third experiment, a business simulation gaming session was organized for graduate students group (N=26) and the participants played the simulation game in virtual teams, which were organizationally and geographically dispersed but connected via technology (Study IV). Each team in all experiments had three to four students and students were between 22 and 25 years old. The business computer games used for the empirical experiments presented an enormous number of complex operations in which a team leader needed to make the final decisions involved in leading the team to win the game. These gaming environments were interactive;; participants interacted by solving the given tasks in the game. Thus, strategy and appropriate leadership were needed to be successful. The training was competition-­based and required implementation of leadership skills. The data of these studies consist of observations, participants’ reflective essays written after the gaming sessions, pre-­ and post-­tests questionnaires and participants’ answers to open-­ ended questions. Participants’ interactions and collaboration were observed when they played the computer games. The transcripts of notes from observations and students dialogs were coded in terms of transactional, transformational, heroic and post-­heroic leadership styles. For the data analysis of the transcribed notes from observations, content analysis and discourse analysis was implemented. The Multifactor Leadership Questionnaire (MLQ) was also utilized in the study to measure transformational and transactional leadership styles;; in addition, quantitative (one-­way repeated measures ANOVA) and qualitative data analyses have been performed. The results of this study indicate that in the business simulation gaming environment, certain leadership characteristics emerged spontaneously. Experiences about leadership varied between the teams and were dependent on the role individual students had in their team. These four studies showed that simulation gaming environment has the potential to be used in higher education to exercise the leadership styles relevant in real-­world work contexts. Further, the study indicated that given debriefing sessions, the simulation game context has much potential to benefit learning. The participants who showed interest in leadership roles were given the opportunity of developing leadership skills in practice. The study also provides evidence of unpredictable situations that participants can experience and learn from during the gaming sessions. The study illustrates the complex nature of experiences from the gaming environments and the need for the team leader and role divisions during the gaming sessions. It could be concluded that the experience of simulation game training illustrated the complexity of real life situations and provided participants with the challenges of virtual leadership experiences and the difficulties of using leadership styles in practice. As a result, the study offers playing computer simulation games in small teams as one way to exercise leadership styles in practice.

Nietzsche's eternal recurrence of the same : the effect of logic abridgement, contradictions and inconsistencies

I will argue that the doctrine of eternal recurrence of the same no better interprets cosmology than pink elephants interpret zoology. I will also argue that the eternal-reiurn-of-the-same doctrine as what Magnus calls "existential imperative" is without possibility of application and thus futile. To facilitate those arguments, the validity of the doctrine of the eternal recurrence of the same will be tested under distinct rubrics. Although each rubric will stand alone, one per chapter, as an evaluation of some specific aspect of eternal recurrence, the rubric sequence has been selected to accommodate the identification of what I shall be calling logic abridgments. The conclusions to be extracted from each rubric are grouped under the heading CONCLUSION and appear immediately following rubric ten. Then, or if, at the end of a rubric a reader is inclined to wonder which rubric or topic is next, and why, the answer can be found at the top of the following page. The question is usually answered in the very first sentence, but always answered in the first paragraph. The first rubric has been placed in order by chronological entitlement in that it deals with the evolution of the idea of eternal recurrence from the time of the ancient Greeks to Nietzsche's August, 1881 inspiration. This much-recommended technique is also known as starting at the beginning. Rubric 1 also deals with 20th. Century philosophers' assessments of the relationship between Nietzsche and ancient Greek thought. The only experience of E-R, Zarathustra's mountain vision, is second only because it sets the scene alluded to in following rubrics. The third rubric explores .ii?.ih T jc,i -I'w Nietzsche's evaluation of rationality so that his thought processes will be understood appropriately. The actual mechanism of E-R is tested in rubric four...The scientific proof Nietzsche assembled in support of E-R is assessed by contemporary philosophers in rubric five. E-R's function as an ethical imperative is debated in rubrics six and seven.. .The extent to which E-R fulfills its purpose in overcoming nihilism is measured against the comfort assured by major world religions in rubric eight. Whether E-R also serves as a redemption for revenge is questioned in rubric nine. Rubric ten assures that E-R refers to return of the identically same and not merely the similar. In addition to assemblage and evaluation of all ten rubrics, at the end of each rubric a brief recapitulation of its principal points concludes the chapter. In this essay I will assess the theoretical conditions under which the doctrine cannot be applicable and will show what contradictions and inconsistencies follow if the doctrine is taken to be operable. Harold Alderman in his book Nietzsche's Gift wrote, the "doctrine of eternal recurrence gives us a problem not in Platonic cosmology, but in Socratic selfreflection." ^ I will illustrate that the recurrence doctrine's cosmogony is unworkable and that if it were workable, it would negate self-reflection on the grounds that selfreflection cannot find its cause in eternal recurrence of the same. Thus, when the cosmology is shown to be impossible, any expected ensuing results or benefits will be rendered also impossible. The so-called "heaviest burden" will be exposed as complex, engrossing "what if speculations deserving no linkings to reality. To identify ^Alderman p. 84 abridgments of logic, contradictions and inconsistencies in Nietzsche's doctrine of eternal recurrence of the same, I. will examine the subject under the following schedule. In Chapter 1 the ancient origins of recurrence theories will be introduced. ..This chapter is intended to establish the boundaries within which the subsequent chapters, except Chapter 10, will be confined. Chapter 2, Zarathustra's vision of E-R, assesses the sections of Thus Spoke Zarathustra in which the phenomenon of recurrence of the same is reported. ..Nihilism as a psychological difficulty is introduced in this rubric, but that subject will be studied in detail in Chapter 8. In Chapter 2 the symbols of eternal recurrence of the same will be considered. Whether the recurrence image should be of a closed ring or as a coil will be of significance in many sections of my essay. I will argue that neither symbolic configuration can accommodate Nietzsche's supposed intention. Chapter 3 defends the description of E-R given by Zarathustra. Chapter 4, the cosmological mechanics of E-R, speculates on the seriousness with which Nietzsche might have intended the doctrine of eternal recurrence to be taken. My essay reports, and then assesses, the argument of those who suppose the doctrine to have been merely exploratory musings by Nietzsche on cosmological hypotheses...The cosmogony of E-R is examined. In Chapter 5, cosmological proofs tested, the proofs for Nietzsche's doctrine of return of the same are evaluated. This chapter features the position taken by Martin ' Heidegger. My essay suggests that while Heidegger's argument that recurrence of the same is a genuine cosmic agenda is admirable, it is not at all persuasive. Chapter 6, E-R is an ethical imperative, is in essence the reporting of a debate between two scholars regarding the possibility of an imperative in the doctrine of recurrence. Their debate polarizes the arguments I intend to develop. Chapter 7, does E-R of the same preclude alteration of attitudes, is a continuation of the debate presented in Chapter 6 with the focus shifted to the psychological from the cosmological aspects of eternal recurrence of the same. Chapter 8, Can E-R Overcome Nihilism?, is divided into two parts. In the first, nihilism as it applies to Nietzsche's theory is discussed. ..In part 2, the broader consequences, sources and definitions of nihilism are outlined. My essay argues that Nietzsche's doctrine is more nihilistic than are the world's major religions. Chapter 9, Is E-R a redemption for revenge?, examines the suggestion extracted from Thus Spoke Zarathustra that the doctrine of eternal recurrence is intended, among other purposes, as a redemption for mankind from the destructiveness of revenge. Chapter 10, E-R of the similar refuted, analyses a position that an element of chance can influence the doctrine of recurrence. This view appears to allow, not for recurrence of the same, but recurrence of the similar. A summary will recount briefly the various significant logic abridgments, contradictions, and inconsistencies associated with Nietzsche's doctrine of eternal recurrence of the same. In the 'conclusion' section of my essay my own opinions and observations will be assembled from the body of the essay.

Gender and Genre in 21st Century Visions of Sherlock Holmes

Sherlock Holmes has been one of the most-adapted characters in literature since his first appearance in A Study in Scarlet in Beeton's Christmas Annual in 1887. Each new adaptation must offer innovations that bring freshness and contemporary appeal to time-worn stories and concepts or risk irrelevancy; analyzing these changes closely sheds light on shifts in societal constructs. Taking this as a starting point, this thesis examines Sherlock and Elementary from a perspective of feminism and queer theory via methods of discourse and genre analyses, with texts ranging from 1931 to the present as objects of comparison. The research illuminates constructions of masculinity as they have changed over time, particularly the movement from an orderly, stable, rational construction of hegemonic masculinity to one that is chaotic, often violent, and anti-heroic in at least some aspects while still being invested in the status quo.

Le processus suivi par les pairs aidants lors de leur expérience auprès d’adolescents suicidaires

Depuis plusieurs années, on assiste à la création de programmes en prévention du suicide à l’adolescence. L’un de ces programmes repose sur le principe des pairs aidants. Il consiste à former des jeunes dont le rôle est d’apporter du soutien à des camarades qui vivent des difficultés. Or, à notre connaissance, aucune étude n’a comme préoccupation spécifique l’aide apportée par un pair aidant à un élève suicidaire. C’est pourquoi le but de notre étude est de comprendre et d’interpréter le processus suivi par les pairs aidants lors de leur expérience auprès d’un adolescent suicidaire. Nous avons effectué des entrevues auprès de cinq anciens pairs aidants qui avaient joué ce rôle entre une et trois années auparavant. À cause de sa pertinence pour ce type d’étude, l’approche méthodologique choisie a été la théorisation ancrée. La proposition qui a émergé de l’analyse des données est que l’expérience de pairs aidants auprès d’adolescents suicidaires est une mission héroïque à la fois stimulante, « confrontante » et enrichissante. Pour rendre compte de la globalité de cette expérience, vécue comme une mission invitant le pair aidant à prendre un rôle de « héros », trois étapes ont été distinguées. La première étape commence par l’accès au statut de pair aidant. Après être entré en contact avec un camarade suicidaire, le pair aidant s’engage dans la mission de le sauver. Le pair aidant est alors « tout feu tout flamme » dans son rôle de héros sauveur. Au cours de la seconde étape seront considérés les faits entourant la mission. L’aide s’engage comme un combat pour « sauver » l’élève suicidaire. L’enthousiasme « tout feu tout flamme » du début se tempère dans l’ambivalence du combat que représente l’aide concrète. C’est la période d’une certaine désillusion. La dernière étape s’amorce après que soit terminée l’aide qu’a fournie le pair aidant. Il fait le point sur les victoires et les défaites qu’a comportées cette mission. C’est alors le moment de la sagesse. Au cours de l’analyse, certaines données ont suscité la réflexion. Nous avons donc effectué une seconde recension des écrits reliés au processus de venir en aide à un adolescent suicidaire en tant que pair aidant. À la fin de cette étude, nous pensons que le programme de pairs aidants a des répercussions positives pour l’adolescent impliqué.

Iphigénie de Rotrou à Racine : paradoxe d'un héroïsme chrétien au féminin

Dans la France de l’Ancien Régime, si les représentations de la condition féminine légitiment les valeurs d’une traditionnelle phallocratie, on note néanmoins que le dogme chrétien accorde aux femmes une place dans l’économie du salut. Dans un contexte de Contre-Réforme, celle-ci déterminera notamment, sur le plan socio-littéraire, les modalités de l’expérience mystique et de l’héroïsme au féminin : l’éthique chrétienne érige paradoxalement en modèle des figures féminines qui transcendent leur humanité dans le sacrifice et la mort. Mais au XVIIe siècle, l’évolution des notions d’abnégation et d’amour-propre éradique ce triomphe éphémère. En nous intéressant plus particulièrement aux remaniements de l’hypotexte euripidien dans l’Iphygenie de Rotrou (1640) et dans l’Iphigénie de Racine (1674), nous verrons comment les deux pièces traduisent ce déclin. Au premier chapitre de notre mémoire, nous nous intéresserons à l’espace de liberté que le discours chrétien confère aux femmes à travers le culte de la virginité et l’hypothétique transfiguration des corps célestes. Réintégrant ces données théologiques, la mystique marque l’essor d’un charisme féminin que la notion d’amour-propre déconstruira à l’ère classique. Dans un second chapitre, nous explorerons les développements de l’éthique héroïque qui ont servi à l’essor d’un héroïsme au féminin. Le troisième chapitre portera enfin sur l’échec d’une héroïne mythique qui, mettant à profit le dogme chrétien, menace dangereusement l’équilibre d’un ordre patriarcal. La critique littéraire convient généralement de l’irréfutable vertu de l’héroïne de Rotrou et de Racine. Au terme de notre analyse, nous entendons démontrer qu’Iphigénie est, a contrario, tragiquement reconnue coupable d’amour-propre par les deux dramaturges.

Le discours de guerre tenu aux enfants montréalais au sujet de la Première Guerre mondiale entre 1914 et 1918

L’étude du discours de guerre destiné aux enfants de Montréal, entre 1914 et 1918, concernant la Première Guerre mondiale n’a pas retenu l’attention des historiens canadiens. Pourtant, à travers une analyse des journaux montréalais, des revues pédagogiques du Québec, de certains écrits gouvernementaux, il est possible de comprendre comment la guerre est expliquée aux enfants. Ce mémoire vise à mettre en relief les caractéristiques et les objectifs du discours de guerre destiné aux enfants montréalais d’âge primaire. Le premier chapitre s’attardera aux connaissances factuelles transmises aux enfants afin d’établir les raisons qui leur sont présentées quant aux origines de la guerre. Nous constaterons la mise en place d’un triple discours : un discours de peur, un discours visant à rassurer et un discours culpabilisant pour sensibiliser les enfants à l’effort de guerre canadien. Le chapitre suivant analyse les principales caractéristiques des récits de guerre proposés aux enfants. Nous serons ainsi en mesure de cerner les objectifs de ce genre d’histoires. Enfin, nous verrons la place de l’enfant dans le discours de guerre. Nous montrerons comment l’enfant des récits de guerre devient un acteur dans le conflit et comment les écrits utilisent les actions héroïques enfantines. Dans cette guerre qui insiste sur la mobilisation de tous, le discours s’adresse aux filles et, surtout, aux garçons. La Première Guerre mondiale est un sujet incontournable à tel point qu’elle sert de prétexte pour inculquer aux enfants certaines connaissances traditionnelles et nouvelles. Elle s’immisce dans le quotidien de l’enfant, à l’école, dans ses loisirs et dans ses corvées familiales. L’enfant doit développer son patriotisme et les qualités « naturelles » propres à son sexe : les garçons doivent apprendre à faire la guerre et les filles à la soutenir. Le discours de guerre cherche à embrigader l’enfant dans l’effort de guerre canadien. Il insiste sur plusieurs nouvelles thématiques qui auparavant ne faisaient pas partie des enseignements habituels, comme la situation géopolitique de la Belgique. Il incite les petits Montréalais à devenir de bons futurs citoyens qui sauront, si l’occasion se représente, donner leur vie pour leur pays, mais, dans l’immédiat, il les incite surtout à participer à l’effort de guerre.

Hubert Aquin et la Gnose

Reprendre contact avec les réalités de l’âme, rouvrir la source où l’être rejaillit éternellement : tel est l’idéal occulte, inavouable, d’où procède la poétique d’Hubert Aquin. Depuis sa jeunesse, Aquin s’emploie clandestinement à défaire les mailles de la conscience et à rebrousser chemin vers les arrière-plans ténébreux du Moi, vers le Plérôme de la vie nue. Il manœuvre pour se mettre au service de l’intentionnalité impersonnelle inscrite au plus profond de sa psyché, pour devenir l’instrument du vouloir aveugle « qui opère en lui comme une force d’inertie ». Son œuvre ne s’accomplit pas dans le texte, mais à rebours du texte, voire à rebours du langage ; elle se déploie sur le terrain d’une confrontation enivrée avec le Négatif — avec la Parole sacrée issue de l’abîme. En d’autres termes, elle prend la forme d’une Gnose, c’est-à-dire d’un exercice de dé-subjectivation, de destruction de soi, consistant à réaliser la connaissance participative de l’empreinte imaginale scellée derrière les barreaux de la finitude. Essentiellement consacrée à l’analyse de la dimension gnostique de l’œuvre d’Hubert Aquin, cette thèse vise à montrer que la connaissance du hiéroglyphe mystérieux gravé au fond de l’âme n’est pas une sinécure. Il s’agit plutôt d’un opus contra naturam qui comporte bien des risques (en tout premier lieu celui d’une inflation psychique). Pourtant, ce travail est aussi, aux yeux de l’auteur, le seul véritablement digne d’être accompli, celui qui donne à l’homme le moyen de se soustraire à l’engloutissement de la mort et la possibilité de renaître. Comme l’écrit Aquin dans un texte de jeunesse, l’ouverture inconditionnelle au Négatif (la destruction de soi) est « une façon privilégiée d’expérimenter la vie et un préalable à toute entreprise artistique » ; elle correspond à « un mode supérieur de connaissance », à un savoir « impersonnel » qui offre immédiatement le salut.
