Violência, ideologia e estranhamento na era das imagens virtuais.

O texto trata do impacto dos videojogos na cultura e na sociedade contemporâneas. Procura demonstrar que nas experiências vivenciadas, através desses jogos e acessórios (óculos, capacetes, joysticks), há uma espécie de simbiose entre a sensação física real e a representação virtual, que permite criar um simulacro da realidade que funciona como um bálsamo para as desesperanças. Para orientar a discussão abordar-se-á dois temas-eixo dos jogos eletrônicos – a violência e o mito do herói – não só por serem recorrentes ou suscitarem polêmica e inquietação particularmente entre não-jogadores, mas por serem reveladores de algumas particularidades da sociabilidade contemporânea.

Força de trabalho feminina no Brasil: no interior das cifras

Teoricamente, este artigo foi elaborado do ponto de vista do FEMINISMO, compreendido este enquanto uma nova perspectiva científico-politica. Por conseguinte, rejeita-se a posição do denominado feminismo radical, segundo a qual as relações de gênero constituem o principio fundamental estruturador das sociedades capitalistas, assim como se refuta a posição daqueles que reduzem a textura complexa das sociedades de classes a lutas de classe. O feminismo como perspectiva cientificopolítica não apenas leva em consideração estes dois antagonismos, como também suas interrelações. Daí deriva a concepção deste tipo de sociedade em termos de capitalismo-patriarcado e não como capitalismo patriarcal. À luz deste esquema teórico de referência é examinada, ao longo da história, a desigual incorporação da mulher na força de trabalho brasileira. Se durante o período 1872-1982 os dados a respeito deste fenômeno sofreram mudanças, houve, por outro lado, muita conservação de fenômenos discriminatórios contra a mulher, no interior das estatísticas. Ou seja, o grosso das trabalhadoras continua ocupando posições subalternas, recebendo salários mais baixos pelo desempenho da mesma função, exercendo duas jornadas de trabalho. Estes fenômenos como também os que deles decorrem, só poderão ser eliminados pela luta contra o patriarcado-capitalismo, pela destruição desta simbiose, que propicia a dominaçâo-exploração de quase todos por muitos e de mulheres por homens.

Contaminação por fungos antes e após limpeza e desinfecção de colchões hospitalares

OBJECTIVE: To verify the existence of fungal contamination prior to and following the cleaning and disinfection process of hospital mattresses used by patients with Candidemia. METHODS: Cross-sectional study analyzing 25 mattresses used by patients with Candidemia confirmed by blood culture from different hospital wards. The study made use of convenience samples. After growing the samples in an Agar Sabouraud Dextrose environment, isolated yeasts were identified by macroscopic, microscopic and physiologic characteristics. RESULTS: Analyses showed 15 (60%) mattresses contaminated by Candida spp. From these, 10 (66.7%) and five (33.3%) mattresses corresponded respectively to the collection prior to and following disinfection, with Candida parapsilosis being the isolated species with the highest frequency. CONCLUSION: Considering that half of the mattresses remained contaminated after cleaning and disinfection, there is a risk that these mattresses may act as potential secondary reservoirs in the infection chain.

The effect of an Er,Cr:YSGG laser on external adaptation of healthy and decayed cavities

The aim of this study was to evaluate the influence of chlorhexidine and Er, Cr:YSGG laser irradiation on the bond strength and external adaptation in mixed healthy and caries-affected class V cavities before and after thermal cycling. Thirty-six cavity preparations were made in mixed class V buccal human molars, half of them being artificially caries-induced. Any remaining affected dentin was removed from the cavity with a round burr at low speed. The teeth were divided into six groups, according to cleaning agent for both healthy and caries-induced dentin: no treatment, chlorhexidine and erbium, chromium-doped: yttrium, scandium, gallium, garnet (Er,Cr:YSGG) laser irradiation. A Filtek P90 (3M ESPE, St Paul, MN, USA) silorane adhesive restorative system was used. The specimens were subjected to 5000 thermal cycles (5-55 degrees C 60 min). Epoxy replicas were obtained to characterize the external adaptation under scanning electron microscopy. The average percentages of non-continuous margins were 5.41% and 6.49% in enamel dentin before thermal cycling and 25% and 33.7% after thermal cycling, respectively. The caries-affected and laser irradiated cavities showed higher non-continuous margins. Thermal cycling was able to raise the percentage of non-continuous margin for all groups. Chlorhexidine did not affect the marginal adaptation results, and the Er,Cr:YSGG laser irradiation showed significantly worse results compared with the control group.

Performance and carcass quality of feedlot- or pasture-finished Nellore heifers according to feeding managements in the postweaning phase

The objective of this study was to evaluate the postweaning history of heifers kept on marandu grass pastures with three canopy heights, in a continuous-grazing system, during the rainy period, on feedlot-or pasture finishing. The effects of three canopy heights (15, 25 and 35 cm) associated with two supplements (mineral salt and protein-energy supplement) and two finishing systems in the dry period (feedlot and open pasture) were studied in the postweaning period during the rainy season. The adopted design was completely randomized, with seven replications (animals) in a 2 x 2 factorial arrangement. The animals which received protein-energy supplement reached the finishing period with greater body weight in relation to those fed mineral salt. In both feedlot and pasture finishing systems, compensatory gain effect was observed in the animals that remained on the low pastures during postweaning compared with the high pastures. This compensatory gain was not verified in the animals that received protein-energy supplement in relation to the mineral salt, and thus the animals were slaughtered beforehand. The heifers on pastures with 25 or 35 cm in height were slaughtered in the same period, and those kept on the low pastures were slaughtered afterwards. The studied factors in the postweaning phase did not affect the carcass characteristics. Animals finished in feedlot slaughtered with the same body weight as those finished on pasture show greater carcass yield, subcutaneous fat deposition and renal pelvic and inguinal fat and greater losses with trimmings for cleaning the main hindquarter meat cuts; however, they provide cuts with the same weight but greater fat cover.
