Uma questão de método: origens, limites e possibilidades da etnografia para a psicologia social

O presente trabalho, eminentemente voltado à metodologia de pesquisa em psicologia social, organiza-se em torno de três objetivos: definir em maiores detalhes algumas das principais características da etnografia, realizar um breve percurso histórico acerca das suas origens como prática cientificamente legitimada e, finalmente, discutir a sua atual utilização. De maneira conclusiva, enfatiza não apenas os limites, mas também as possibilidades da prática etnográfica, sustentando que a experiência de estranhamento que tradicionalmente a caracterizou continua trazendo em si mesma tanto o dinamismo quanto o potencial crítico necessários para manter em movimento o pensamento sobre ou, se preferirmos, com a diferença.

Taxonomic Characters in the Genus Echinococcus (Cestoda: Taenlidae)

Not more than four species of cestodes of the genus Echinococcus Rudolphi, 1801, are recognized as valid. The larval stage of at least three of them is able to develop in man, causing respective types of hydatid disease. Accurate characterization of these cestodes, including both larval and adult stages, is essential for identification, upon which depends development of methods for preventing infection of man and domestic animals. Because morphological characteristics of the larval cestodes may be modified according to the species of host in which they develop, identification should be based upon taxonomic characters of specimens from the respective natural hosts, which can be identified by means of ecological investigations in endemic areas in combination with controlled infection of experimental animals. The morphological and biological characteristics of the known species are discussed, and the two species most important to public health and economically--E. granulosus (Batsch, 1786) and E. multilocularis Leuckart, 1863--are distinguished. French résumé: Trois espèces de cestodes du genre Echinococcus Rudolphi, 1801 ont été identifiées: E. granulosus (Batsch, 1786); E. multilocularis Leuckart, 1863; et E. oligarthrus (Diesing, 1863). On n'a pas encore déterminé avec certitude s'il fallait leur adjoindre E. patagonicus Szidat, 1960. Ce dernier mis à part, tous ces ténias sont connus pour provoquer chez l'homme des formes spécifiques d'échinococcose hydatique; l'infestation par les larves de E. granulosus est également fréquente chez les ongulés domestiques et la répartition de ce cestode est presque cosmopolite. E. multilocularis est très largement répandu dans l'hémisphère nord, tandis que E. oligarthrus ne se trouve que dans le centre et le sud de I'Amérique. Pour définir des critères morphologiques qui permettent de distinguer avec précision les différentes espèces d'Echinococcus, il convient de prendre les spécimens sur leurs hôtes naturels, sinon l'évolution du stade strobilaire se trouve habituellement retardée et le stade larvaire présente une gamme étendue de variations morphologiques. Pour identifier les hôtes naturels, il faut étudier l'écologie dans les zones d'éndemicité, ainsi que les manifestations de l'infection contrôlée chez des animaux d'expérience. Le stade strobilaire des ténias peut présenter plusieurs caractères spécifiques importants qui concernent notamment la taille, le nombre et la répartition des testicules, la position du pore génital dans les segments gravides, la forme de l'utérus gravide et, dans certains cas, la taille et la forme des crochets du rostre. La structure de la larve normalement développée est caractéristique de chacune des trois espèces relativement bien connues. Les caractéristiques biologiques jouent également un rôle important dans la différenciation de ces cestodes. Au stade larvaire, le laps de temps nécessaire au développement des scolex infectants est directement fonction de la durée de vie de l'hôte intermédiaire. La larve de E. multilocularis présente des scolex infectants dès le deuxième ou le troisième mois, alors qu'ils n'apparaissent qu'au bout d'un ou deux ans chez la larve de E. granulosus. Un tableau donne la liste comparative des caractéristiques taxonomiques qui permettent de faire la distinction entre ces deux espèces.

O governo estadual na experiência política brasileira: os desempenhos legislativos das assembléias estaduais

Este artigo analisa o volume e a dinamica da produção legislativa em 12 assembléias legislativas estaduais brasileiras durante duas legislaturas, 1999-2002 e 2002-2006. Em primeiro lugar, constatamos que a dinâmica legislativa das assembléias estaduais depende dos recursos institucionais conferidos constitucionalmente aos atores políticos pela Carta de 1988 que restringe a legislação proposta pelos deputados estaduais e limita a autonomia legislativa do Governador. Apesar de indícios claros da existência de uma dinâmica partidária relevante e um jogo efetivo entre governo e oposição nas assembléias que explica as variações encontradas entre os estados. Em segundo lugar, sinalizamos uma dinâmica legislativa estadual diversificada que não se restringe ao predomínio do poder executivo. O volume de propostas apresentadas pelos deputados estaduais que não distribuem benefícios concentrados sinaliza para uma agenda pelo menos "desejada", principalmente direcionada a definir normas e diretrizes das políticas públicas estaduais. Por outro lado, é evidente que o sucesso legislativo dos deputados estaduais é elevado se comparado ao dos deputados federais, mas basicamente restrito a uma categoria de norma: a concessão de benefícios concentrados, destacando-se a categoria das declarações de utilidades públicas. O esforço de pesquisa aqui empreendido e os dados apresentados chamam a atenção para a necessidade de futuras pesquisas sobre as assembléias estaduais em busca de uma melhor compreensão do funcionamento das instituições brasileiras no âmbito subnacional.

Le désert et la littérature de voyage européenne du XIXe siècle

L'Europe commence à découvrir le désert à la fin du XVIIIe siècle. Ce milieu présente des aspects multiples aux premiers explorateurs, qui le décrivent comme un lieu vivant et varié. La géopolitique constitue le premier approche d'analyse : le désert peut être rendu plus viable si mieux administré, donc libre de la domination ottomane. Au cours du siècle, le tourisme se développe, aussi en raison de la colonisation ; l'expérience du désert devient commune, et les voyageurs partent en quête d'une expérience spirituelle aussi bien que d'une aventure. Le désert devient un écran de projection pour la rêverie et les souvenirs des Européens (la Bible et les topos traditionnels demeurent actifs dans l'imaginaire occidental) ; seules certaines caractéristiques de ce milieu sont dès lors appréciées par les voyageurs. Ensuite, avec l'âge du Réalisme, devient objet d'appréciation de la part des peintres. Grâce à la médiation de l'art, la littérature commence à regarder au désert d'un point de vue esthétique, et elle lui reconnaît un charme de la nudité et du dépouillement. La mort et le minéral caractérisent ce milieu vers la fin du siècle ; le désert se vide, et devient le "désert de sable" que nous tous connaissons aujourd'hui.

What is Practice Research in Social Work - Definitions, Barriers and Possibilities

Practice is subject to increasing pressure to demonstrate its ability to achieve outcomes required by public policy makers. As part of this process social work practice has to engage with issues around advancing knowledge-based learning processes in a close collaboration with education and research based perspectives. This has given rise to approaches seeking to combine research methodology, field research and practical experience. Practice research is connected to both “the science of the concrete” – a field of research oriented towards subjects more than objects and “mode 2 knowledge production” – an application-oriented research where frameworks and findings are discussed by a number of partners. Practice research is defined into two approaches: practice research – collaboration between practice and research – and practitioner research – processes controlled and accomplished by practitioners. The basic stakeholders in practice research are social workers, service users, administrators, management, organisations, politicians and researchers. Accordingly, practice research is necessarily collaborative, involving a meeting point for different views, interests and needs, where complexity and dilemmas are inherent. Instead of attempting to balance or reconcile these differences, it is important to respect the differences if collaboration is to be established. The strength of both practice and research in practice research is to address these difficult challenges. The danger for both fields is to avoid and reject them.

Empfehlungen zur Diagnostik und Therapie der behavioralen und psychologischen Symptome der Demenz (BPSD)

In patients with dementia, Behavioral and Psychological Symptoms of Dementia (BPSD) are frequent findings that accompany deficits caused by cognitive impairment and thus complicate diagnostics, therapy and care. BPSD are a burden both for affected individuals as well as care-givers, and represent a significant challenge for therapy of a patient population with high degree of multi-morbidity. The goal of this therapy-guideline issued by swiss professional associations is to present guidance regarding therapy of BPSD as attendant symptoms in dementia, based on evidence as well as clinical experience. Here it appears to be of particular importance to take into account professional experience, as at this point for most therapeutic options no sufficiently controlled clinical trials are available. A critical discussion of pharmaco-therapeutic intervention is necessary, as this patient-population is particularly vulnerable for medication side-effects. Finally, a particular emphasis is placed on incorporating and systematically reporting psycho-social and nursing options therapeutic intervention.

[Collagenase injection in Dupuytren's disease, evaluation of the ultrasound assisted technique].

Since October 2011, the enzymatic lysis of Dupuytren's cord was introduced in Switzerland (Xiapex(®), Auxilium Pharmaceuticals, Pfizer). Here we present our first university experience and underline the major role of ultrasound during the injection. Between December 2011 and February 2013, 52 injections were performed to eliminate 43 Dupuytren's cords in 33 patients. The mean age of the patients was 64.4 ± 8.5 years. Complications were documented for each patient. Before, directly after and after a minimum of 6 months post-injection, the contracture of the treated joint was measured with use of a goniometer. The DASH score was evaluated after a minimum of 6 months and the patients were asked to subjectively evaluate the outcome of the treatment (very good, good, mild, poor) and whether they would reiterate it if necessary. Four skin defects, one lymphangitis, and one CRPS were responsible for a complication rate of 18%. There was no infection and no tendon rupture in the series. The mean MCP joint contracture was respectively 36.8 ± 27.4°, 3.5 ± 7.8° (gain of mobility compared to the preoperative situation 33.3°, P<0.001), and 8.4 ± 13.9° (gain 28.4°, P<0.001) respectively before, just after and at the long-term clinical control. The mean PIP joint contracture was respectively 36.5 ± 29.1°, 5.9 ± 6.7° (gain 30.6°, P<0.001), and 15.1 ± 13.8° (gain 21.4°, P<0.001) respectively before injection, just after and at the long-term clinical control. The DASH score decreased from 24 ± 14 to 7 ± 9 (P<0.001). Eighty-one per cent of the patients were satisfied or very satisfied of the treatment. All but two would reiterate the treatment if necessary. Ultrasound is able to target the injection of collagenase in order to reduce complications. The short-term results of this non-invasive therapy are very promising however comparison with conventional procedures is difficult as the long-term results are lacking.
