Corpus ex machina : a ciborguização da enfermeira no contexto da terapia intensiva

A pesquisa busca analisar as tensões humano-máquina em materiais pedagógicos utilizados pela enfermagem em terapia intensiva e, entre esses materiais pedagógicos foram analisados os manuais e protocolos assistenciais. Para desenvolvê-la, apóio-me na teorização cultural e no trabalho de autores e autoras que têm problematizado a noção de corpo e de sujeito na pós-modernidade a partir dos pressupostos teóricos do pós-estruturalismo. Entre os/as autores /as utilizados, indico os estudos de Donna Haraway e seu entendimento de ciborgue – uma idéia produtiva que possibilita explorar a ciborguização da cultura contemporânea e suas implicações para a enfermagem em terapia intensiva. Utilizo a abordagem metodológica da análise cultural tal como esta vem sendo desenvolvida pelos Estudos Culturais que se aproximam do Pós-estruturalismo, para descrever e analisar, em três lições, alguns dos diferentes tipos de ciborguização que se materializam na prática da enfermagem em terapia intensiva. Para tal intento, selecionei alguns acontecimentos que sintetizam significados importantes da terapia intensiva na contemporaneidade, a saber: o atendimento avançado de reanimação cardiorrespiratória, a produção de imagens de corpos doentes através de um complexo sistema de monitoramento e o deslocamento das fronteiras entre a vida e a morte. Com base nessa análise, discuto no final, os desdobramentos dessas tensões no discurso da humanização da assistência na área da saúde.

Aprendizagem de escrita de língua de sinais pelo sistema SignWriting : língua de sinais no papel e no computador

Esta tese trata de como o sistema SignWriting pode servir de suporte a uma nova proposta pedagógica ao ensino da escrita de língua de sinais e letramento para crianças surdas usuárias da Língua Brasileira de Sinais - Libras e da Língua de Sinais Francesa - LSF. Escrever deve ser uma atividade significativa para a criança. No caso da criança surda, a escrita fundamenta-se em sua competência na língua de sinais, sem precisar da intermediação da língua oral. A criança surda, quando em um ambiente onde ela e seus colegas se comunicam em língua de sinais, efetivamente tenta escrever sinais, quando é incentivada a fazê-lo. Em nossos experimentos, usamos o sistema SignWriting para mostrar ás crianças surdas (e a seus pais e professores) como escrever textos em línguas de sinais de ambas as formas: manuscrita e impressa, usando o programa Sign Writer para editar textos em línguas de sinais. A base teórica que apóia a tese é a abordagem bilíngüe para a educação de surdos, a língua de sinais, a teoria de Piaget, e de Ferreiro quando trata das etapas da alfabetização em língua oral. Esta investigação possui um caráter exploratório, em que o delineamento metodológico é dado pela pesquisa-ação. O primeiro estudo apresenta um levantamento do processo de aquisição da escrita de sinais, em sua forma manuscrita, pela criança e jovem surdo no Brasil e na França. O segundo estudo trata da ajuda que a informática pode dar a essa aquisição e de como utilizamos os softwares de escrita de língua de sinais em aulas de introdução ao uso do computador e em transcrições da LSF de corpus vídeo para a escrita de língua de sinais. Os resultados sugerem que as crianças evoluem em sua escrita, pois muitos signos que elas escreveram não foram sugeridos pela experimentadora, nem por outro meio, mas surgiram espontaneamente. A introdução de um software como o Sign Writer ou o SW-Edit nas classes para introduzir as TI traz a essas aulas muito maior interesse do que quando usamos um editor de textos na língua oral. Também as produções das crianças são mais sofisticadas. As conclusões indicam que a escrita de língua de sinais incorporada à educação das crianças surdas pode significar um avanço significativo na consolidação de uma educação realmente bilíngüe, na evolução das línguas de sinais e aponta para a possibilidade de novas abordagens ao ensino da língua oral como segunda língua.

Acordo Tripartite Itaipu-Corpus : ponto de inflexão entre a disputa geopolítica e a política de cooperação

A aproximação na Bacia do Prata é um dos poucos caminhos que os países do contexto regional têm à sua disposição perante os problemas comuns. Entretanto, apesar desta convicção, durante anos as tentativas de convergência foram sobrestadas pela rivalidade brasileiro- argentina, cujas origens remontam à secular disputa geopolítica mantida na região desde a época da dominação luso-espanhola. E, a partir de meados do século passado, conflitos advindos da exploração do potencial fluvial daquela com finalidades hidrelétricas somaram-se aos antagonismos históricos. O presente trabalho analisa o contencioso binacional que decorre da decisão brasileira de construir a Hidrelétrica de Itaipu à revelia dos projetos argentinos para aproveitamento dos recursos propiciados pelo Rio Paraná. A conseqüente crise perdura por mais de uma década, durante a qual a hipótese de confronto armado está sempre presente e as políticas dos países são baseadas na correlação de forças a nível regional; esta, na época, é claramente favorável ao Brasil. Finalmente, como resultado de um longo processo de negociações, é assinado o Acordo Tripartite Itaipu-Corpus, que equaciona o problema da utilização dos recursos hídricos e permite que Brasil e Argentina iniciem uma nova etapa nas suas relações recíprocas, caracterizada pela superação das antigas tensões. Deste modo, as notas diplomáticas trocadas pelos signatários em 19 de outubro de 1979 representam um marco simbólico, ponto de inflexão entre a disputa geopolítica e a política de cooperação, o qual é alcançado apesar dos países envolvidos serem governados por regimes militares de exceção.

A formação de professores surdos de Libras: a centralidade de ambientes bilíngues em sua formação

The study object of this thesis intertwines the history of deaf education in the last 30 years in three schools for the deaf in the cities of Campina Grande, Gado Bravo and Aroeiras, Paraiba, the life stories of six deaf teachers of brasilian sign language (Libras) that have formed and works in these educational institutions for the deaf and our own journey, as a teacher and researcher. The study was conducted on the theoretical-methodological principles of (auto)biographical research in education and socio-historical studies on the social formation of the human. The corpus used for analysis was consisted of six narrative interviews conducted in sign language and transcribed into portuguese, documents and personal files and institutional. The analysis allowed us to define three hinge moments of this story: the creation of the first school for the deaf, within the framework of oralism (1980 - 1991), the passage into the Total Communication (1991 - 1995) and, finally, the introduction of Bilingualism (1995 to today). The analyzes show that the trajectories of teacher formation of the research participants reflect the history of the three schools which have costituted bilingual social spaces of paramount importance to the subjects and the deaf community as a group of linguistic and cultural minority. The evolution of this trajectory has allowed to demarcate between the two generations of research participants. The generation of heirs of oralism, which had delayed access to the Libras and lived an education referenced in oralism, whose reminiscences of childhood and adolescence are strongly marked by suffering for the lack of communication, which hinders their social and professional career until today. And the generation of the sons of bilingualism, the youngest in age, who had childhood access to Libras and education within the framework of bilingualism, whose reminiscences are not marked by suffering and have a positive vision of the future. With respect to your teacher formation, three figures stand out as a teacher. The teacher's improvised, closer to the first generation of teachers who were called to teach without proper training. The figure of the teacher craftsman, which corresponds to the image that most of them have of yourself now, understanding that their knowledge are based on the exchange between peers. And finally the figure of the real teacher, which stands on the horizon of expectations as future graduates in Letters |Libras. The narratives allowed to realize that the evolution between these figures is based on the contributions of the other: hearing teachers of EDAC and the Federal University of Campina Grande and deaf teachers of the two generations who learn from each other. The analyzes and reflections allowed to defend the thesis of the centrality of bilingual environments for the establishment of the deaf person as a citizen with full rights, based on the voice of the deaf, muted by the history of education, conducted by listeners

Effect of breed and corpus luteum on pregnancy rate of bovine embryo recipients

The objective of this study was to evaluate pregnancy rates of recipients of different breed groups (Nellore and crossbreed), as well as the effects of size and type of the corpus luteum (CL) on plasmatic concentrations of progesterone and pregnancy rates of embryo recipients. A total of 152 heifers were synchronized with progesterone implants and on the day of embryo transfer, previously obtained by superovulation and frozen in ethylene glycol, the diameter and type of the corpus luteum (cavitary and compact) was measured and blood was collected for progesterone measurement. The pregnancy rate was 44.1%, with a diameter of corpus luteum higher in recipients that became pregnant (2.03±0.41) compared with non-pregnant ones (1.86±0.34 cm). Plasmatic concentrations of progesterone did not differ between pregnant (1.50±1.05) and non-pregnant (1.31±0.91 ng/mL) animals. The type of corpus luteum did not influence the pregnancy rates. Only Angus and crossbred Marchigiana differ among themselves in pregnancy rates (33.3 and 59.2%, respectively). The pregnancy probability was affected only by CL diameter, but not by P4 plasmatic concentration. Selection of the corpus luteum size at the time of embryo transfer is an important factor to increase pregnancy rates in recipients, and compact and cavitary corpora lutea do not influence the pregnancy rates of bovine embryo recipients. Nellore recipients have pregnancy rates that are satisfactory and comparable to crossbred (Bos taurus × Bos indicus) recipients.

Cartas oficiais norte-riograndenses dos séculos XVIII, XIX e XX : constituição e caracterização de um corpus diacrônico

The diachronic studies marked the first decades of the 20th century in Brazilian linguistics, passing by an ostracism period after the 50s. Mainly from the 90s especially with the project, created in 1997, Para a história do português brasileiro (PHPB), which has systemized, in national ambit, the programme related to the area of diachrony the historical studies retake forces and have gradually increased since then. Our work is set in the new scene of Brazilian historical linguistics and it is associated to two research programmes: i) the constitution of a diachronic corpus; ii) the diachrony of text and discourse. As regards the first programme, we made effort to constitute a diachronic corpus of official letters about Rio Grande do Norte, we called cartas oficiais norte-rio-grandenses, written in 18th, 19th and 20th centuries. The chosen for bureaucrat letters occurred for they represent a textual category very productive in historical contexts, mostly 18th and 19th centuries, in which the command of writing was the least and also because they bring, almost always explicitly, the information of where, when, for whom and from whom, as remembers Fonseca (2003). The rules for constituting the corpus were based, although not strictly, on the orientation from PHPB. In respect to the second programme, we set up on the ideas of coserian base came from the studies on discourse traditions (TD) (Koch, 1997; Kabatek, 2006) amongst which that the texts are shaped so as to follow their own tradition (Coseriu, 2007), and we turned to Diplomatics (Belloto, 2002) in order to do the characterization of this corpus by the application of concepts from Diplomatics and TD as well as by the presentation of the structures that form those official letters: their textual genres, a kind of TD, with their macrostructures; and some of their formulaic expressions (microstructures), another sort of TD. This stage of characterizing will pay attention, as far as possible, to the dynamic between tradition and innovation that happen in the actualization of those textual structures along the centuries. This work intends to contribute with the researches connected to Historical Linguistics in Rio Grande do Norte, more specifically the ones related to the constitution of diachronic corpora and to TD; and with the study of official documents, textual category about which there are almost no studies (cf. Silveira, 2007)

Tatuagem da palavra : educação sentimental do corpo no corpus poético de Maria Teresa Horta

While looking to the body and finding it engraved by cultural, imaginary and power-related texts through a discourse embodied in itself, this research proposes a new vertiginous approach to it by analyzing the following works: Poesia completa II, more specifically, Educação sentimental, and Novas cartas portuguesas. Such transgressive and performatic works are from Maria Teresa Horta (1937-), Portuguese writer, who proposes a new education by a renewed language: a sentimental education spawned from the erotic element. Starting from the deconstruction of the view over the spoiled body and exposed in Novas cartas portuguesas, from the poetic texts in Educação sentimental, as well as in remaining ones in Poesia completa II, Horta disassembles and reassembles the body, giving a new meaning to the symbols that surround us and our experiences. Other than proposing to all, men and women, such new meaning of the behavior and current practices models, Horta s education allows, through a performance action, the construction of a stage for female identity, free from the phallic influence. A new identity, able to handle all holy and profane characteristics of women, discarding the chromatic lens of sin. Horta s poetry emerges as a new proposal of literary labor

In vitro PGF2 alpha production by endometrium and corpus luteum explants from pregnant and nonpregnant diestrus bitches and placental explants from pregnant bitches

To better understand the process of slow luteal regression of the nonpregnant cycle in dogs and the acute luteolysis that occurs prepartum, the present study investigated in vitro PGF2 alpha production by the endometrium, corpus luteum and placental explants obtained at known times of the cycle from pregnant bitches (days 63, 64 and immediately postpartum; day 0 = estimated day of the ovulatory LH surge) and from nonpregnant diestrus bitches (approximately days 65, 75 and 85). Both basal PGF2 alpha production and its production in the presence of the protein kinase C (PKC) stimulator 12,13-phorbol dibutyrate (PDBu) were determined. For PDBu-supplemented incubations, mean PGF2 alpha production (pg/mL/mg/6 h) by endometrium explants of the nonpregnant bitches in late diestrus was highest on day 65 (205 +/- 87) and reduced to low levels (38 +/- 17 and 11 +/- 11) on days 75 and 85, respectively. The production by corpus luteum explants from these bitches was significantly less on day 65 (46 +/- 14) than that of the day 65 endometrium explants, and was slightly increased on day 85 (103 +/- 52). The corresponding mean PGF2 alpha production by the endometrium explants of pregnant bitches was on average much greater (i.e., two to three-fold) compared to nonpregnant bitches (P < 0.01) and involved high concentrations at day 64 (1523 +/- 467) and postpartum, compared to somewhat lower levels on day 63 (830 +/- 65); luteal PGF production (165 +/- 4) was also higher than in nonpregnant bitches around day 65. For pregnant bitches, PGF production per gram of tissue in the endometrium explants was greater than for the CL or placenta explants (180 +/- 37). Therefore, the endometrium of the pregnant bitch has an increased capability to produce PGF2a immediately prepartum, which on a tissue weight basis, exceeds that of either corpora lutea or the placenta. However, assuming a larger mass of placental tissue in vivo, we inferred that the placenta may contribute substantially to peripheral PGF concentrations. (c) 2006 Published by Elsevier B.V.

Canine corpus luteum regression: Apoptosis and caspase-3 activity

The present study evaluated the occurrence of apoptosis and caspase-3 activity in the canine corpus luteum during the period of luteal regression in eight pregnant and nine nonpregnant diestrus bitches. Intact luteal cells were obtained from corpora lutea in both peripartum pregnant bitches and nonpregnant diestrus bitches at approximately 65 d (range 63-68) after estrus, but not at days 75 and 85 in nonpregnant bitches. In all bitches, apoptotic cells were rarely detected and when present, those cells were more easily detected using the hematoxylin and eosin technique than using the critical electrolyte concentration technique. The luteal structures at 75 and 85 d of diestrus had histological characteristics similar to a corpus albicans. Caspase-3 activity was detected in morphologically normal corpora lutea from both pregnant and diestrus bitches around day 65, and also in the later structures considered corpus albicans tissue. These results suggested that apoptosis may not be the major mechanism involved in canine functional luteal regression, and that caspase-3 participated in both functional and morphological luteolysis and in the tissue reorganization involved in corpus albicans formation.
