Uma análise do regime jurídico da cooperativa à luz do conceito de empreendedorismo social

Partindo da análise do regime jurídico das cooperativas, constante do Código Cooperativo português, este estudo conclui que as cooperativas apresentam um perfil jurídico adequado ao desenvolvimento de projetos enquadráveis no conceito de empreendedorismo social. Efetivamente, as cooperativas desenvolvem uma missão social — que resulta, sobretudo, da obediência aos princípios cooperativos, nos quais se destaca a necessária convivência de uma dimensão social com uma dimensão económica —; assentam num modelo de governança democrático e participado, ainda que hoje se reclame uma maior profissionalização dos membros dos órgãos de gestão das cooperativas; não assentam a distribuição de resultados no critério da participação no capital social; e a escassez de recursos financeiros, em muitos casos propiciada pelo próprio regime jurídico cooperativo, leva a que as cooperativas, por força do princípio da intercooperação, se envolvam em processos de integração e cooperação de modo a assegurarem a sustentabilidade da organização.

Pré-hipertensão e hipertensão em adultos de Florianópolis: estudo de base populacional

OBJETIVO: Estimar a prevalência e os fatores associados de pré-hipertensão e hipertensão arterial em adultos. MÉTODOS: Estudo transversal, de base populacional, com 1.720 adultos em Florianópolis, SC, de setembro de 2009 a janeiro de 2010. Informações demográficas, socioeconômicas, comportamentos relacionados à saúde, medidas antropométricas, morbidades e autopercepção de saúde foram coletadas por meio de entrevistas domiciliares. Níveis de pressão arterial sistólica e diastólica foram avaliados. Adicionalmente perguntou-se sobre a ingestão de medicamentos e diagnóstico médico para hipertensão. A variável dependente foi categorizada em normal, pré-hipertensão e hipertensão arterial. A regressão logística politômica múltipla foi empregada com uso do modelo Logit multinomial. RESULTADOS: A prevalência de pré-hipertensão e hipertensão arterial foi de 36,1% (IC95% 33,3;38, 8) e 40,1% (IC95% 36,6;43,5), respectivamente. A análise de regressão politômica múltipla revelou que a pré-hipertensão esteve associada a homens, cor de pele preta, faixa etária acima de 50 anos, inativos fisicamente no lazer e com pré-obesidade. A hipertensão arterial esteve associada a homens, cor de pele preta, faixa etária acima de 40 anos, tercil intermediário de renda per capita, escolaridade menor que 12 anos, inativos fisicamente, pré-obesidade, obesidade, circunferência da cintura elevada e percepção negativa do estado de saúde. CONCLUSÕES: Para controlar a hipertensão arterial na população adulta de Florianópolis, é urgente haver políticas públicas eficazes para o combate à pré-hipertensão.

Ansiedade na performance: causas e possíveis curas

I - Este relatório pretende descrever o estágio especializado em ensino de música realizado no âmbito do mestrado em Ensino de Música na Escola Superior de Música de Lisboa. Este estágio decorreu no Instituto Gregoriano de Lisboa e no Conservatório de Música, de Dança e de Arte Dramática de Lisboa, duas escolas de ensino oficial especializado. Sendo a primeira pública e a segunda privada, estas escolas apresentam realidades muito diferentes do ponto de vista organizacional e de gestão, que resultam em situações heterogéneas e dependentes de vários factores que serão mencionados ao longo deste relatório. A análise SWOT efectuada para cada uma destas organizações descreve mais objectivamente os factores e variáveis que permitiram construir este relatório. Foram caracterizados três alunos, um de cada curso: preparatório, básico e secundário. A Maria M. é a aluna do 2º ano do curso preparatório, o Pedro R. é aluno de 3º grau do curso básico de instrumento e o Diego M. é aluno de 7º grau. Foram aprofundadas as práticas pedagógicas desenvolvidas com cada um dos alunos e os avanços e metas atingidas por cada um destes alunos. Este estágio resulta numa reflexão sobre a prática pedagógica aplicada e as suas motivações.

Superoxide reductase from the syphilis spirochete Treponema pallidum

Superoxide reductase is a 14 kDa metalloprotein containing a catalytic nonhaem iron centre [Fe(His)4Cys]. It is involved in defence mechanisms against oxygen toxicity, scavenging superoxide radicals from the cell. The oxidized form of Treponema pallidum superoxide reductase was crystallized in the presence of polyethylene glycol and magnesium chloride. Two crystal forms were obtained depending on the oxidizing agents used after purification: crystals grown in the presence of K3Fe(CN)6 belonged to space group P21 (unit-cell parameters a = 60.3, b = 59.9, c = 64.8 A ° , = 106.9 ) and diffracted beyond 1.60 A ° resolution, while crystals grown in the presence of Na2IrCl6 belonged to space group C2 (a = 119.4, b = 60.1, c = 65.6 A ° , = 104.9 ) and diffracted beyond 1.55 A ° . A highly redundant X-ray diffraction data set from the C2 crystal form collected on a copper rotating-anode generator ( = 1.542 A ° ) clearly defined the positions of the four Fe atoms present in the asymmetric unit by SAD methods. A MAD experiment at the iron absorption edge confirmed the positions of the previously determined iron sites and provided better phases for model building and refinement. Molecular replacement using the P21 data set was successful using a preliminary trace as a search model. A similar arrangement of the four protein molecules could be observed.

Deported Mexican migrants: health status and access to care

OBJECTIVE To describe the health status and access to care of forced-return Mexican migrants deported through the Mexico-United States border and to compare it with the situation of voluntary-return migrants. METHODS Secondary data analysis from the Survey on Migration in Mexico’s Northern Border from 2012. This is a continuous survey, designed to describe migration flows between Mexico and the United States, with a mobile-population sampling design. We analyzed indicators of health and access to care among deported migrants, and compare them with voluntary-return migrants. Our analysis sample included 2,680 voluntary-return migrants, and 6,862 deportees. We employ an ordinal multiple logistic regression model, to compare the adjusted odds of having worst self-reported health between the studied groups. RESULTS As compared to voluntary-return migrants, deportees were less likely to have medical insurance in the United States (OR = 0.05; 95%CI 0.04;0.06). In the regression model a poorer self-perceived health was found to be associated with having been deported (OR = 1.71, 95%CI 1.52;1.92), as well as age (OR = 1.03, 95%CI 1.02;1.03) and years of education (OR = 0.94 95%CI 0.93;0.95). CONCLUSIONS According to our results, deportees had less access to care while in the United States, as compared with voluntary-return migrants. Our results also showed an independent and statistically significant association between deportation and having poorer self-perceived health. To promote the health and access to care of deported Mexican migrants coming back from the United States, new health and social policies are required.

Study of the rheology of self-compacting concrete with fine recycled concrete aggregates

This work studies the effect of incorporating fine recycled aggregates on the rheology of self-compacting concrete over time (at 15,45 and 90 min). The fine fraction of the natural aggregates was replaced at 0%, 20%, 50% and 100% with recycled sand. The fresh-state properties were studied by empirical tests (slump-flow, J-Ring, L-Box) and fundamental ones in an ICAR rheometer. The mixes with 50% and 100% recycled sand lost their SCC characteristics at 90 min. Contrarily the mix with 20% replacement maintained suitable passing and filling ability. The causes of this trend were an initial increase of plastic viscosity and afterwards an increase of yield stress. The compressive strength of the 50% and 100% replacement mixes decreased significantly and that of the 20% replacement mix less than 10%. (C) 2015 Elsevier Ltd. All rights reserved.

Cardiac sympathetic-parasympathetic balance in rats with experimentally-induced acute chagasic myocarditis

To clarify the mechanism responsible for the transient sinus tachycardia in rats with acute chagasic myocarditis, we have examined the cardiac sympathetic-parasympathetic balance of 29 rats inoculated with 200,000 parasites (Trypanosoma cruzi). Sixteen infected animals and 8 controls were studied between days 18 and 21 after inoculation (acute stage). The remaining 13 infected animals and 9 controls were studied between days 60 and 70 after inoculation (sub-acute stage). Under anesthesia (urethane 1.25 g/kg), all animals received intravenous atenolol (5 mg/kg) and atropine (10 mg/kg). Acute stage: The baseline heart rate of the infected animals was significantly higher than that of the controls (P < 0.0001). The magnitude of the negative chronotropic response to atenolol was 4 times that of the controls (P < 0.00001). This response correlated with the baseline heart rate (r= - 0.72, P < 0.001). The heart rate responses to the beta-blocker and to atropine, of the infected animals studied during the sub-acute stage, were not different from controls. These findings suggest that cardiac sympathetic activity is transiently enhanced and cardiac parasympathetic activity is not impaired, in rats with acute chagasic myocarditis. The transient predominance of cardiac sympathetic activity could explain, in part, the sinus tachycardia observed in the acute stage of experimentally-induced chagasic myocarditis.

Heart rate responses to a muscarinic agonist in rats with experimentally induced acute and subacute chagasic myocarditis

We administered arecoline to rats, with experimentally induced chagasic myocarditis, in order to study the sinus node sensitivity to a muscarinic agonist. Sixteen month old rats were inoculated with 200,000 T. cruzi parasites ("Y" strain). Between days 18 and 21 (acute stage), 8 infected rats and 8 age-matched controls received intravenous arecoline as a bolus injection at the following doses: 5.0, 10.0, 20.0, 40.0, and 80.0 mug/kg. Heart rate was recorded before, during and after each dose of arecoline. The remaining 8 infected animals and 8 controls were subjected to the same experimental procedure during the subacute stage, i.e., days 60 to 70 after inoculation. The baseline heart rate, of the animals studied during the acute stage (349 ± 68 bpm, mean ± SD), was higher than that of the controls (250 ± 50 bpm, p < 0.005). The heart rate changes were expressed as percentage changes over baseline values. A dose-response curve was constructed for each group of animals. Log scales were used to plot the systematically doubled doses of arecoline and the induced-heart rate changes. The slope of the regression line for the acutely infected animals (r = - 0.99, b =1.78) was not different from that for the control animals (r = - 0.97, b = 1.61). The infected animals studied during the subacute stage (r = - 0.99, b = 1.81) were also not different from the age-matched controls (r = - 0.99, b = 1.26, NS). Consequently, our results show no pharmacological evidence of postjunctional hypersensitivity to the muscarinic agonist arecoline. Therefore, these results indirectly suggest that the postganglionic parasympathetic innervation, of the sinus node of rats with autopsy proved chagasic myocarditis, is not irreversibly damaged by Trypanosoma cruzi.

Effects of dual-task training on balance and executive functions in Parkinson's disease: A pilot study

The aim of this study was to analyze the efficacy of cognitive-motor dual-task training compared with single-task training on balance and executive functions in individuals with Parkinson's disease. Fifteen subjects, aged between 39 and 75 years old, were randomly assigned to the dual-task training group (n = 8) and single-task training group (n = 7). The training was run twice a week for 6 weeks. The single-task group received balance training and the dual-task group performed cognitive tasks simultaneously with the balance training. There were no significant differences between the two groups at baseline. After the intervention, the results for mediolateral sway with eyes closed were significantly better for the dual-task group and anteroposterior sway with eyes closed was significantly better for the single-task group. The results suggest superior outcomes for the dual-task training compared to the single-task training for static postural control, except in anteroposterior sway with eyes closed.
