Prácticas festivas y formas de sociabilidad de y entre varones homosexuales (ciudad de córdoba, 1976-1986) Parties and Forms of Sociability between and among Male Homossexuals (City of Córdoba AR, 1976-1986)

El presente proyecto de investigación está interesado en explorar y describir determinadas formas de sociabilidad de varones de clase media auto definidos como homosexuales entre el inicio de la última dictadura (1976) y la formación de un circuito de discos y pubs gays en la ciudad de Córdoba durante el llamado “destape alfonsinista” (1986). La investigación contempla la descripción densa de dos series de prácticas de sociabilidad. Por una parte, se analizará la sociabilidad de varones homosexuales, especialmente de un conjunto de sujetos que desempeñaban determinadas profesiones como “decoradores”, “modistos”, “cocineros”, “anticuarios” y organizadores de fiestas, contratados por las elites locales y clases medias acomodadas para diseñar sus formas de diversión durante el período. ¿Cómo estos sujetos se relacionaban con quienes no forman parte del “ambiente” homosexual y cómo gestionaban el “secreto público” de su identidad erótico-sexual en sus relaciones con las elites cordobesas? El estudio de estas formas de sociabilidad homosexual escasamente trabajadas por la literatura internacional se relacionará con un análisis de las formas de sociabilidad entre varones homosexuales y la formación de un “ambiente”. Para ello se estudiarán espacios colectivos de socialización como baños públicos, plazas, calles, fiestas privadas, bares, boliches y saunas. Los códigos de comunicación verbal y gestual utilizados en esos espacios, y la caracterización de las redes de personas que componían el “ambiente” también serán objeto de análisis. Dado el carácter inicial de esta investigación, ya que no se cuenta con estudios previos para Córdoba, proponemos la siguiente hipótesis de tipo exploratorio en relación a las formas de sociabilidad de determinados varones homosexuales: Estos sujetos habrían asegurado su reproducción social tanto como la posesión de ciertos salvoconductos para el ejercicio de su identidad sociosexual produciendo fiestas de las elites locales. A partir de erigirse en árbitros del “buen gusto” dichos sujetos habrían asegurado ciertos privilegios, entre ellos “feminizar” sus gustos y producirse como “locas”. Dada las nuevas condiciones impuestas por la recuperación democrática, los salvoconductos se hicieron cada vez menos valiosos al mismo tiempo que se formaba una identidad “gay” que, aunque buscó distanciarse del modelo negativo de “la loca”, continuó reclamando su dominio sobre el “buen gusto”. De esta manera, el cultivo experto del “buen gusto” sería parte de las prácticas que organizaban las formas de sociabilidad de varones homosexuales con sujetos heterosexuales de las elites. En relación a las formas de sociabilidad entre homosexuales proponemos que durante la dictadura, “el ambiente” se habría organizado en torno a un circuito callejero y una territorialidad de eventos privados (fiestas negras). Las diferentes performances sociales desarrolladas en tales espacios formaron parte de prácticas que desafiaron el estado de sitio impuesto. Reprimidas por la dictadura, estas prácticas no podían formar parte de un consumo cultural mercantilizado. La recuperación democrática y los cambios en las políticas del Estado con relación a los derechos y los reclamos de las minorías articulados con la expansión de un mercado gay global, habrían producido un cambio en las formas de sociabilidad homosexual. El ejercicio de esta sociabilidad supuso cada vez más el consumo de ciertas mercancías culturales asociadas con “la noche”. Así, la formación de una identidad “gay”, como opuesta al modelo “loca/chongo” dominante hasta los años ´80, aparecería fuertemente relacionada con la formación y segmentarización de un mercado del entretenimiento nocturno. Para la recolección de datos se recurrirá a entrevistas focalizadas e historias de vida de sujetos que trabajaron dando forma a las prácticas de divertimento nocturno de las elites locales y participaron en las redes de personas que componían el “ambiente”. This research project aims at exploring and describing determined forms of sociability among middle class self-identified as homossexual males betwwen the beginning of the last dictatorial period (1976) and the establishment of a network of disco and gay pubs in Cordoba, AR, during the so called “destape alfonsinista” (1986). This research will deal with the thick description of two series of sociability practices. On the one hand, it will analyze male homossexuals sociability practices themselves, barely studied in international literature, mainly those of a set of subjects whose professional careers were those of interior decorators, dressmakers, kitchen chefs, antiquarians and party promoters hired by the local elites and upper middle classes to design their forms of leisure durign that period. On the other, we will deal with the forms of sociability between male homossexuals and the the set of a social environment. This rearch will study collective spaces of socialization such as restrooms, squares, streets, private parties, pubs, discos and saunas. The communication codes in those spaces, both verbal and gestural, as well as the description of the social networks componing that enviroment will also be considered. Focused interviews with and life histories of those who worked structuring night leisure local elite practices and were part of that environment social networks will be the main techniques used in data collection.

Efeitos da pressão positiva contínua nas vias aéreas na insuficiência cardíaca crônica

FUNDAMENTO: A insuficiência cardíaca pode apresentar disfunção assintomática à descompensação, com limitações e diminuição da capacidade produtiva. A pressão positiva contínua nas vias aéreas (CPAP) é um meio não farmacológico de redução da pós-carga. OBJETIVO: Analisar os efeitos da CPAP (10 cmH2O), por 30 dias, em paciente com insuficiência cardíaca crônica. MÉTODOS: Avaliamos 10 pacientes, com diversas etiologias, idade média de 54 ± 14 anos, sexo (masc.= 6 e fem.= 4), com IMC de 21 ± 0,04 kg/m². A terapia foi ofertada por 60 min., 5 vezes por semana, durante 1 mês, no período diurno. Foram analisados ecocardiograma e ergoespirometria, antes e após 30 dias de terapia. RESULTADOS: Apresentou aumento de 19,59% na fração de ejeção do ventrículo esquerdo (FEVE): 23.9 ± 8.91 vs 27.65 ± 9.56%; p = 0,045. Na ergoespirometria, o tempo de exercício (Tex) apresentou aumento significante de 547 ± 151,319 vs 700 ± 293,990 seg., p = 0,02, o consumo de oxigênio (VO2) foi de 9,59 ± 6,1 vs 4,51 ± 2,67 ml.kg-1.min.-1 , p = 0,01, enquanto a produção de dióxido de carbono (VCO2) de repouso (9,85 ± 4,38 vs 6,44 ± 2,88 ml.kg-1.min.-1 , p = 0,03) apresentou diminuição. CONCLUSÃO: A CPAP provocou aumento na fração de ejeção do ventrículo esquerdo e no tempo de exercício, diminuiu o consumo de oxigênio e a produção de dióxido de carbono no repouso.

Stroke

Stroke is a preventable and treatable disease. It can present with the sudden onset of any neurological disturbance, including limb weakness or numbness, speech disturbance, visual loss or disturbance of balance. Over the last two decades, a growing body of evidence has overturned the traditional perception that stroke is simply a consequence of aging which inevitably results in death or severe disability. Evidence is accumulating for more effective primary and secondary prevention strategies, better recognition of people at highest risk and thus most in need of active intervention, interventions that are effective so on after the onset of symptoms, and an understanding of the processes of care that contribute to a better outcome. In addition, there is now good evidence to support interventions and care processes in stroke rehabilitation. In the UK, the National Sentinel Stroke Audits 2,3 have documented changes in secondary care provision over the last 10 years, with increasing numbers of patients being treated in stroke units, more evidence-based practice, and reductions in mortality and length of stay. In order for evidence from research studies to improve outcomes for patients, it needs to be put into practice. National guidelines provide clinicians, managers and service users with summaries of evidence and recommendations for clinical practice. Implementation of guidelines in practice, supported by regular audit, improves the processes of care and clinical outcome. This guideline covers interventions in the acute stage of a stroke (‘acute stroke’) or transient ischaemic attack (TIA). Most of the evidence considered relates to interventions in the first 48 hours after onset of symptoms, although some interventions of up to 2 weeks are covered as well. This guideline is a stand-alone document, but is designed to be read alongside the Intercollegiate Stroke Working Party guideline ‘National clinical guideline for stroke’* which considers evidence for interventions from the acute stage into rehabilitation and life after stroke. The Intercollegiate Stroke Working Party guideline is an update of the 2004 2nd edition and includes all the recommendations contained within this guideline. This acute stroke and TIA guideline is also designed to be read alongside the Department of Health’s (DH) ‘National stroke strategy’ (NSS). Where there are differences between the recommendations made within this acute stroke and TIA guideline and the NSS, the Guideline Development Group (GDG) members feel that their recommendations are derived from systematic methodology to identify all of the relevant literature.

Estudos sôbre o quiabeiro II: efeitos da autofecundação e do cruzamento

The present work deals with the study of the effects of selfing and crossing in pures lines of okra inbred for five generations and the methods of breeding in this plant. This work is party of a large program of this Dept. to study heterosis in plants naturally self pollinated. The technic of selfing consists of tying with a string the floral bud before anthesis. To make controlled crosses, it is necessary to emasculate the flowers removing the anthers with small forceps, and to cover the flowers with a bag and wait for 1 or 2 days until the blooming. Also, the male parents are covered with paper bags prior to flowering. Finally, the pollen is brushed lightly over the stigma of the emasculated flowers and the females unit rebagged. The authors have tried without sucess the technic of soda fountain straw used for cotton. The treatments were: I) Fl of the cross pure-line x foreign variety (not improved by breeding). II) Fl of the cross pure-line x parental variety and III) pure-line 5 generations inbred. In order to compare the production of these three treatments, a randomized blocks with 4 replications was designed; since we had 6 families in each treatment, the total number was: 4 replications x 3 treatments x 6 families: = 72. Each familiy was planted in lines of 10 plants. Owing to the design devised, the present experiment corresponds to a split-plot. The analysis of variance of the number and the weight of the pods is given in tables 2 and 4, and shows the following: 1) The production expressed in both numbers and weights of the cross, - pure lines x foreign variety - was statistically smaller than the others treatments, i, e., the cross of pure-lines x parental variety and the pure-lines; 2) The production of the treatments pure-lines x parental variety and selfed purelines was the same. It was proved that the selfing do not produce harmful effects in okra, it was benefical, since after 5 inbred generations the production was the same when compared with Fl of the parental variety. Also, the methods of pure-lines are indicated to improve varieties of okra.

Benthic macroinvertebrates as bioindicators of water quality in an Atlantic forest fragment

The objective of this study was to evaluate benthic macroinvertebrate communities as bioindicators of water quality in five streams located in the "Reserva Particular do Patrimônio Natural" (RPPN) Mata Samuel de Paula and its surroundings, in the municipality of Nova Lima near the city of Belo Horizonte, Minas Gerais State, southeastern Brazil. This region has been strongly modified by human activities including mining and urbanization. Samples were collected in the field every three months between August 2004 and November 2005, totaling six samplings in the rainy and dry seasons. This assessment identified one area ecologically altered while the other sampling sites were found to be minimally disturbed systems, with well-preserved ecological conditions. However, according to the Biological Monitoring Work Party (BMWP) and the Average Score Per Taxon (ASPT) indices, all sampling sites had excellent water quality. A total of 14,952 organisms was collected, belonging to 155 taxa (148 Insecta, two Annelida, one Bivalvia, one Decapoda, one Planariidae, one Hydracarina, and one Entognatha). The most abundant benthic groups were Chironomidae (47.9%), Simuliidae (12.3%), Bivalvia (7.5%), Decapoda (6.1%), Oligochaeta (5.2%), Polycentropodidae (3.7%), Hydropsychidae (2.5%), Calamoceratidae (1.8%), Ceratopogonidae (1.7%), and Libellulidae (1.2%). The assessment of the benthic functional feeding groups showed that 34% of the macroinvertebrates were collector-gatherers, 29% predators, 24% collector-filterers, 8% shredders, and 5% scrapers. The RPPN Mata Samuel de Paula comprises diversified freshwater habitats that are of great importance for the conservation of many benthic taxa that are intolerant to organic pollution.
