The tricks of the trade (un)exposed

One of the filmic trends which has been neglected by the Academy Awards is the metacinema, which for practical purposes I will consider to be a cross between the complexities of the self-reflexive cinema (highly connoted with modernism) and the Hollywood Film (the classical films about the urge to ‘make it’ in Hollywood). Indeed, these films have always existed and some, as Sunset Boulevard (Billy Wilder, 1950, USA) and Mulholland Dr. (David Lynch, 2001, FRA/USA), have even made it to the ceremony, but were, predictably, defeated in the main categories, by other more ‘serious’ or less self-reflexive products. The United States has always insisted on not revealing the tricks of the trade while, ironically, generating films that deal with this theme, in order to cater to the curiosity of the metacinema-inclined spectator. For this reason such films are usually about the universe of cinema but not its medium, at least not in a way that discloses the operations of the technical apparatus. Why are these films not viewed as serious enough and artistic enough to be awarded Oscars by the Academy in the categories of Best Picture, Best Director, Best Screenplay, and Best Cinematography? Are they being discarded for the same reasons that comedy and musicals usually are? Or are they being punished for being too unveiling? Or is the industry going for commercial products that can easily be pushed on a global scale and make a profit?

Cultura organizacional e desempenho: o impacto da cultura organizacional no desempenho financeiro

Esta dissertação visa o estudo da influência da cultura organizacional no desempenho financeiro das organizações. Nesse contexto, procuramos analisar qual a cultura predominante das organizações, de forma a estabelecer posteriormente uma relação entre a cultura e o desempenho das empresas. Para isso a metodologia seguida foi a realização de um inquérito por questionário a empresas da região Douro de Portugal no sentido de obter, através de uma adaptação ao instrumento desenvolvido por Cameron e Quinn (2006), a cultura predominante da empresa, os indicadores financeiros necessários ao nosso estudo assim como, uma caracterização da amostra recolhida. Para análise e tratamento dos dados recolhidos através do inquérito por questionário foi utilizada a ferramenta estatística SPSS que nos permitiu retirar ilações sobre as características da amostra, assim como sobre a relação existente entre cultura organizacional e desempenho financeiro, esta relação foi avaliada através de testes de correlação e regressão linear múltipla. Os resultados sugerem que as variáveis culturais, cultura adocrática, mercado e hierárquica e o número de colaboradores explicam em cerca de 20% o resultado líquido ajustado. Também se verificou um efeito positivo da cultura adocrática e de mercado, embora o efeito da cultura de mercado seja mais forte que o da adocrática, e o efeito negativo da cultura hierárquica, ainda que estes resultados não sejam estatisticamente significativos. Não existem evidências que os tipos de cultura analisados (adocrática, de mercado e hierárquica) estão significativamente associados ao desempenho financeiro, avaliado pelos resultados líquidos ajustados, das empresas analisadas, quer pelos testes de correlação quer pelos resultados da estimação do modelo de regressão linear múltipla.

Shoulder Kinematics Is Not Influenced by External Load During Elevation in the Scapular Plane

The current study aimed to compare the shoulder kinematics (3D scapular orientation, scapular angular displacement and scapulohumeral rhythm) of asymptomatic participants under unloaded and loaded conditions during unilateral shoulder elevation in the scapular plane. We used a repeated-measures design with a convenience sample. Eleven male participants with an age range of 21–28 years with no recent history of shoulder injury participated in the study. The participants performed isometric shoulder elevation from a neutral position to approximately 150 degrees of elevation in the scapular plane in intervals of approximately 30 degrees during unloaded and loaded conditions. Shoulder kinematic data were obtained with videogrammetry. During shoulder elevation, the scapula rotated upwardly and externally, and tilted posteriorly. The addition of an external load did not affect 3D scapular orientation, scapular angular displacement, or scapulohumeral rhythm throughout shoulder elevation (P > .05). In clinical practice, clinicians should expect to observe upward and external rotation and posterior tilt of the scapula during their assessments of shoulder elevation. Such behavior was not influenced by an external load normalized to 5% of body weight when performed in an asymptomatic population.

Intake of milk, but not total dairy, yogurt, or cheese, is negatively associated with the clustering of cardiometabolic risk factors in adolescents

Epidemiologic studies have reported an inverse association between dairy product consumption and cardiometabolic risk factors in adults, but this relation is relatively unexplored in adolescents. We hypothesized that a higher dairy product intake is associated with lower cardiometabolic risk factor clustering in adolescents. To test this hypothesis, a cross-sectional study was conducted with 494 adolescents aged 15 to 18 years from the Azorean Archipelago, Portugal. We measured fasting glucose, insulin, total cholesterol, high-density lipoprotein cholesterol, triglycerides, systolic blood pressure, body fat, and cardiorespiratory fitness. We also calculated homeostatic model assessment and total cholesterol/high-density lipoprotein cholesterol ratio. For each one of these variables, a z score was computed using age and sex. A cardiometabolic risk score (CMRS) was constructed by summing up the z scores of all individual risk factors. High risk was considered to exist when an individual had at least 1 SD from this score. Diet was evaluated using a food frequency questionnaire, and the intake of total dairy (included milk, yogurt, and cheese), milk, yogurt, and cheese was categorized as low (equal to or below the median of the total sample) or “appropriate” (above the median of the total sample).The association between dairy product intake and CMRS was evaluated using separate logistic regression, and the results were adjusted for confounders. Adolescents with high milk intake had lower CMRS, compared with those with low intake (10.6% vs 18.1%, P = .018). Adolescents with appropriate milk intake were less likely to have high CMRS than those with low milk intake (odds ratio, 0.531; 95% confidence interval, 0.302-0.931). No association was found between CMRS and total dairy, yogurt, and cheese intake. Only milk intake seems to be inversely related to CMRS in adolescents.

Liderança e motivação nas entidades responsáveis pela recolha e gestão de resíduos do concelho da Maia

O contexto, o tempo é de mudança. Ainda que o não fosse, falar de gestão de recursos humanos, falar de pessoas, é falar em mudança (ou mudanças). A economia mundial é que dita o presente e o futuro das organizações, privadas ou públicas, com ou sem fins lucrativos, pequenas, médias e grandes. Quando, em 2011, foi chumbado o quarto projeto do Programa de Estabilidade e Crescimento, vivia-se em Portugal um período crítico, ao qual não era alheia a conjuntura internacional de recessão económica. No domínio da Administração Pública, procurava-se redesenhar as organizações, imprimir-lhes uma gestão mais privatística, de otimização de recursos e controlo de custos. Hoje, sabe-se que aquela rejeição do programa político governamental teria outras consequências, as que atualmente os portugueses vêm sentindo. É um período de mudanças radicais, sem precedentes. Como lideram ou como administram os responsáveis pelas organizações, no contexto atual? Quais as qualidades de liderança que imperam em situações de crise e de austeridade? Como reagem líderes e liderados em períodos de recessão ou adversidade? E, sobretudo, como falham uns e são bem-sucedidos outros? Desde logo, há que reconhecer a importância e valorizar o capital humano: atrair, reter e desenvolver. Neste trabalho, procuramos responder aos crescentes interesse e preocupação em redesenhar, reformar e melhorar a gestão na administração pública. Daí o interesse pela motivação e a sua relação com o estilo de liderança adotado nas organizações deste setor, fator determinante para o comprometimento, a eficácia e a produtividade no trabalho. Mais concretamente, o objetivo deste estudo é compreender a relação entre o sistema de gestão que predomina nas entidades responsáveis pela recolha e gestão de resíduos do concelho da Maia e a motivação dos seus colaboradores, assim como a satisfação dos mesmos com a sua chefia. A metodologia de investigação utilizada orienta-se para a abordagem quantitativa, recorrendo-se a técnicas e instrumentos de natureza quantitativa, tais como o questionário de escala de resposta tipo Likert, por considerarmos ser a mais ajustada às pretensões desta investigação.

REPRODUCIBILITY OF ALKALINE ANTIGENS OF Leishmania major-LIKE AND Leishmania (V.) braziliensis EVALUATED BY IgG-ELISA. COMPARISON OF ANTIGENS ADDED OF A PROTEIN INHIBITOR (PMSF) OR NOT

This paper deals with the analysis of 10 batches of L.major-like and L.(V.) braziliensis antigens added or not of a proteases inhibitor evaluated by means of an IgG-ELISA on three consecutive days using positive standard sera from patients with diagnosis of American Leishmaniasis previously tested for the presence of IgG antibodies by means of ELISA. The statistical analysis showed that for L. (V.) braziliensis the PMSF-containing antigen did not show any difference among batches or days of testing; the L.(V.) braziliensis antigen without PMSF showed statistical significance for differences among batches and a two-way ANOVA showed significant differences between antigens. L.major-like antigen prepared with or without PMSF showed differences among batches; all 3 days of testing displayed differences for the PMSF antigen but only for days 1 and 2 for the antigen without inhibitor. A two-way ANOVA showed differences among batches of the antigens but not for antigens with and without the protein inhibitor. According to the statistical analysis the L.major-like antigen added or not of PMSF has shown that it is the choice antigen for mucocutaneous leishmaniasis serology.

IL-2 AND IFN-g, BUT NOT IL-4 SECRETION BY PERIPHERAL BLOOD MONONUCLEAR CELLS (PBMC) ARE RELATED TO CD4+ T CELLS AND CLINICAL STATUS IN BRAZILIAN HIV-1-INFECTED SUBJECTS

It has been reported that production of IL-2 and IFN-g, known as T-helper type 1 cytokines, by peripheral mononuclear cells (PBMC) decreases with progression of HIV infection. In contrast, IL-4 and IL-10 production, Th2 cytokine profile, increases with HIV disease progression. PBMC were evaluated from 55 HIV-infected subjects from Divisão de Imunologia, Hospital das Clínicas, Faculdade de Medicina da Universidade de São Paulo, to "in vitro" cytokines production after 24 hours of stimulation with PHA. Low levels of IL-4 production in both HIV- infected patients and normal subjects, were detected. The patients with CD4+ T cell counts <200 showed a significant decrease of IL-2 and IFN-g production compared to controls. Patients with higher counts of CD4+ T cells (either between 200-500 or >500 cells/mm3) also showed decreased production of IL-2 that was not statistically significant. There was a correlation between IL-2 and IFN-g release with CD4+ T cells counts. HIV-1-infected individuals with CD4+ T cells >500 cells/mm3 showed increased levels of IL-2 and IFN-g, than individuals with CD4+ T cells <500 cells/mm3. In conclusion, we observed a decline of IL-2 and IFN-g production at advanced HIV disease. IL-4 production was not affected during HIV infection. Taken together, these findings suggest that the cytokine profile might be influenced by the HIV infection rather than the cause of disease progression.

Immunoglobulin Fc receptors in clinical strains of Staphylococcus aureus do not confer resistance to Phagocytosis in an in vitro assay

Staphylococcus aureus binds Immunoglobulin G (IgG) on its external surface due to the presence of specific receptors for the Fc domain of this immunoglobulin. This mechanism represents a kind of camouflage against phagocytic cells. In order to confirm that possibility an in vitro evaluation of the phagocytic activity of leukocytes polymorpho-nuclear (PMN) against strains of Staphylococcus aureus was done, comparing 18 strains isolated from clinical samples and 16 from healthy individuals. The presence of Fc receptors was evaluated by haemagglutination (HA) with erythrocytes group A after incubation of the strains with IgG anti blood group A. Phagocytosis of S. aureus was carried out by mixing live bacteria with a suspension of human PMN and incubating at 37 °C for 1 h; survivors were counted as colony forming units by plating. The strains from clinical specimens showed higher HA than those from healthy individuals (p = 0.01); but the former were killed more efficiently than the latter (80-90% and 40%, respectively). It is may be possible that S. aureus showed different behavior in vivo, where could express other virulence factors to prevent the action of phagocytes.
