Temas e regiões nas políticas externas de Lula e Fernando Henrique: comparação do discurso dos dois presidentes

Neste artigo, comparamos o discurso sobre a política externa dos dois presidentes que governaram o País nos últimos 16 anos (Fernando Henrique e Lula). Por meio da técnica de análise de conteúdo, foram avaliados mais de mil pronunciamentos realizados em eventos diplomáticos no Brasil e no exterior. Encontramos semelhanças e diferenças importantes, tanto no que diz respeito às temáticas abordadas quanto nos parceiros que buscaram na arena internacional. Ambos os presidentes privilegiaram os temas referentes à economia, às instituições internacionais e ao relacionamento com os países da América do Sul. Fernando Henrique parece ter tido uma preocupação maior com a questão da democracia e aproximou-se mais dos países europeus. Lula estendeu a sua preocupação com o tema da desigualdade para a arena internacional e abriu maior diálogo com os países asiáticos, do Oriente Médio e, principalmente, da África.

China's rising Soft Power: the role of rhetoric in constructing China-Africa relations

As China turns increasingly to the cultivation of soft power in the course of developing its foreign policy, the use of political rhetoric and its explicit and implicit audiences become more and more important, both on a bilateral level and within the international arena at large. Using the case of China's relations with African countries, this article examines key themes within China's diplomatic narrative regarding its role on the African continent and contrasts with Western and African responses.

Mudanças estratégicas em organizações hospitalares: uma abordagem contextual e processual

O objetivo central do artigo consiste em verificar como ocorreu o processo de mudança estratégica em uma organização hospitalar. Analisam-se, de forma empírica, as mudanças estratégicas ocorridas nos últimos 20 anos no Hospital CBS. São identificadas as condições objetivas do setor - ambiente real, arena cognitiva - como ambiente percebido e a rede de colaboradores que dão suporte às atividades do hospital. O período de mais transformações foi o de 1991 a 1995, e as principais mudanças foram na cultura do hospital, na filosofia de trabalho dos médicos e funcionários, na forma de treinamento dos funcionários, na estrutura organizacional, nos processos e na tecnologia. Detectou-se que a coalizão dominante do hospital sofre apenas influência externa em razão das mudanças tecnológicas e que, internamente, o corpo clínico tem controle sobre o processo de tomada de decisões.

MICROFINANCE AND CLIMATE CHANGE IMPACTS: THE CASE OF AGROAMIGO IN BRAZIL

ABSTRACTThis paper reports an empirical case study on the interface between microfinance and climate change actions. Climate change, which until recently seemed a luxury for the microfinance sector, now appears to be crucial for its future. For their low adaptive capacity, the millions of microfinance clients worldwide happen to be the most vulnerable to a changing climate. However, such an arena is still blurred from an academic viewpoint, and inexistent among Brazilian academia. Therefore, by investigating Brazil’s largest rural MFI, Agroamigo, we aim at providing an empirical contribution to green microfinance. The main conclusion is that, albeit Agroamigo offers important links to climate change initiatives, it will need to take better account of specific vulnerabilities and risks to protect its portfolio and clients better from climate change impacts.

As assimetrias entre as políticas setoriais e a política de planejamento regional no Brasil

O modo de conduzir a formulação das políticas de desenvolvimento regional tem se constituído em ampla arena de embates acadêmicos e técnicos e levado a reflexões sobre os rumos das múltiplas políticas que acompanham esse processo de planejamento regional. Isso, em parte, decorre do processo de globalização e das políticas neoliberais que o acompanham, as quais possuem um forte apelo à competitividade. Essa estratégia de buscar espaços "privilegiados" se fez presente de uma forma intensa em alguns setores produtivos, que, ao usar o espaço como mercadoria, utilizam seu conjunto de atributos (naturais e artificiais) para realizarem-se e reproduzirem-se como parte do sistema. Assim, a proposta de estudo pretende responder a questão: em que medida as políticas públicas setoriais têm dialogado com as políticas de planejamento e desenvolvimento regional no âmbito do governo federal? No caso das políticas de planejamento regional, o recorte espacial é visto como um instrumento que, ao ser aplicado, pode se mostrar capaz de viabilizar a integração de ações multissetorializadas, o que em certa dimensão apontaria para uma maior eficiência do Estado na busca por restabelecer o equilíbrio esgarçado, tornando mais eficiente o planejamento.

Oral health in the family health strategy: a change of practices or semantics diversionism

OBJECTIVE:To evaluate public health dentistry practices of two different family health models. METHODS: Qualitative study conducted with data obtained from focus groups consisting of 58 dentists working in the Family Health Strategy for at least three years between August-October, 2006. The Paideia Family Health Approach was used in the city of Campinas and the Oral Health Initiative as part of the Family Health Strategy was implemented in the city of Curitiba, Southeastern and Southern Brazil, respectively. Data was analyzed using the hermeneutic-dialectic method. Analysis indicators were employed to indicate backwardness, stagnation or progress in oral health practices effective from the implementation of the strategies referred. The indicators used were: work process; interdisciplinary approach; territorialization; capacity building of human resources; health promotion practices; and responsiveness to users' demands. RESULTS: There was progress in user access to services, humanization of health care, patient welcoming and patient-provider relationship. The results related to health promotion practices, territorialization, interdisciplinary approach and resource capacity building indicated a need for technical and operational enhancements in both cities. CONCLUSIONS: Both models have brought about important advances in terms of increased access to services and humanization of health care. Universal access to oral health at all levels of complexity was not achieved in both cities studied. Local health managers and oral health program coordinators must bring more weight to bear in the arena that defines public policy priorities.

Standardization of an ELISA test using a recombinant nucleoprotein from the Junin virus as the antigen and serological screening for arenavirus among the population of Nova Xavantina, State of Mato Grosso

INTRODUCTION: Arenavirus hemorrhagic fever is a severe emerging disease. METHODS: Considering that the levels of antibodies against arenavirus in the Brazilian population are completely unknown, we have standardized an ELISA test for detecting IgG antibodies using a recombinant nucleoprotein from the Junin virus as the antigen. This protein was obtained by inserting the gene of the Junin virus nucleoprotein into the genome of Autographa californica nucleopolyhedrovirus, using the Bac-to-Bac baculovirus expression system. This recombinant baculovirus was used to infect S. frugiperda cells (SF9). RESULTS: The infection resulted in synthesis of high concentrations of recombinant protein. This protein was detected on 12.5% polyacrylamide gel and by means of Western blot. Using the standardized ELISA test, 343 samples from the population of Nova Xavantina were analyzed. We observed that 1.4% of the serum samples (five samples) presented antibody titers against arenavirus. CONCLUSIONS: These results show the population studied may present exposure to arenavirus infection.

Convergent validation study of the Contemplation Ladder for application via telephone in tobacco users

OBJECTIVE: This work was designed to validate the Portuguese version of the Contemplation Ladder, whose purpose is to assess the motivational phase to quit smoking among tobacco users using a telephone service. METHOD: A cross-sectional study was conducted in a nationwide drug use information hotline. In order to assess the convergent validation, the correlation between the Contemplation Ladder and the URICA Scale was calculated, which was previously validated. RESULTS: The study included 271 tobacco users. Statistically significant correlations were found between the Contemplation Ladder scores and the scores of the URICA precontemplation (r=-0.16; p<0.01), action (r=0.15; p<0.01) and maintenance (r=0.18; p<0.01) subscales. The correlation between the URICA Scale compound score and the Contemplation Ladder was also significant (r=0.31; p<0.01). CONCLUSION: The results of our study suggest that the Contemplation Ladder can be an efficient substitute for the URICA scale (whose application lasts at least 20 minutes), without submitting the interviewee to a heavy load of questions. The study presented evidences of convergent validity for the Contemplation Ladder when applied via telephone in tobacco users.

Impact of Intensive Physiotherapy on Cognitive Function after Coronary Artery Bypass Graft Surgery

Background: Coronary artery bypass graft (CABG) is a standard surgical option for patients with diffuse and significant arterial plaque. This procedure, however, is not free of postoperative complications, especially pulmonary and cognitive disorders. Objective: This study aimed at comparing the impact of two different physiotherapy treatment approaches on pulmonary and cognitive function of patients undergoing CABG. Methods: Neuropsychological and pulmonary function tests were applied, prior to and following CABG, to 39 patients randomized into two groups as follows: Group 1 (control) - 20 patients underwent one physiotherapy session daily; and Group 2 (intensive physiotherapy) - 19 patients underwent three physiotherapy sessions daily during the recovery phase at the hospital. Non-paired and paired Student t tests were used to compare continuous variables. Variables without normal distribution were compared between groups by using Mann-Whitney test, and, within the same group at different times, by using Wilcoxon test. The chi-square test assessed differences of categorical variables. Statistical tests with a p value ≤ 0.05 were considered significant. Results: Changes in pulmonary function were not significantly different between the groups. However, while Group 2 patients showed no decline in their neurocognitive function, Group 1 patients showed a decline in their cognitive functions (P ≤ 0.01). Conclusion: Those results highlight the importance of physiotherapy after CABG and support the implementation of multiple sessions per day, providing patients with better psychosocial conditions and less morbidity.

Circulatory and Ventilatory Power: Characterization in Patients with Coronary Artery Disease

Background:Circulatory power (CP) and ventilatory power (VP) are indices that have been used for the clinical evaluation of patients with heart failure; however, no study has evaluated these indices in patients with coronary artery disease (CAD) without heart failure.Objective:To characterize both indices in patients with CAD compared with healthy controls.Methods:Eighty-seven men [CAD group = 42 subjects and healthy control group (CG) = 45 subjects] aged 40–65 years were included. Cardiopulmonary exercise testing was performed on a treadmill and the following parameters were measured: 1) peak oxygen consumption (VO2), 2) peak heart rate (HR), 3) peak blood pressure (BP), 4) peak rate-pressure product (peak systolic HR x peak BP), 5) peak oxygen pulse (peak VO2/peak HR), 6) oxygen uptake efficiency (OUES), 7) carbon dioxide production efficiency (minute ventilation/carbon dioxide production slope), 8) CP (peak VO2 x peak systolic BP) and 9) VP (peak systolic BP/carbon dioxide production efficiency).Results:The CAD group had significantly lower values for peak VO2 (p < 0.001), peak HR (p < 0.001), peak systolic BP (p < 0.001), peak rate-pressure product (p < 0.001), peak oxygen pulse (p = 0.008), OUES (p < 0.001), CP (p < 0.001), and VP (p < 0.001) and significantly higher values for peak diastolic BP (p = 0.004) and carbon dioxide production efficiency (p < 0.001) compared with CG. Stepwise regression analysis showed that CP was influenced by group (R2 = 0.44, p < 0.001) and VP was influenced by both group and number of vessels with stenosis after treatment (interaction effects: R2 = 0.46, p < 0.001).Conclusion:The indices CP and VP were lower in men with CAD than healthy controls.

Dispersão larval radial pós-alimentar em Lucilia cuprina (Diptera, Calliphoridae): profundidade, peso e distância de enterramento para pupação

Blowflies utilize discrete and ephemeral sites for breeding and larval nutrition. After the exhaustion of food, the larvae begin dispersing to search for sites to pupate or for additional food source, process referred as postfeeding larval dispersal. Some aspects of this process were investigated in Lucilia cuprina (Wiedemann, 1830), utilizing a circular arena to permit the radial dispersion of larvae from the food source in the center. To determine the localization of each pupa, the arena was split into 72 equal sectors from the center. For each pupa, distance from the center of arena, weight and depth were determined. Statistical tests were performed to verify the relation among weight, depth and distance of burying for pupation. It was verified that the larvae that disperse farthest are those with lowest weights. The majority of individuals reached the depth of burying for pupation between 7 and 18 cm. The study of this process of dispersion can be utilized in the estimation of postmortem interval (PMI) for human corpses in medico-criminal investigations.

Efeito do tipo de substrato para pupação na dispersão larval pós-alimentar de Chrysomya albiceps (Diptera, Calliphoridae)

As moscas-varejeiras utilizam substratos discretos e efêmeros para posturas dos ovos e para alimentação das larvas. Após a exaustão de recursos, as larvas começam a procurar por um sítio de pupação no habitat ou por mais fonte de alimento adicional (dispersão larval pós-alimentar). No entanto, o tipo de substrato de dispersão pode afetar este processo; assim, procurou-se avaliar o comportamento de dispersão de Chrysomya albiceps (Wiedemann 1819) por meio da localização das pupas em arenas circulares preenchidas com vermiculita, comparando-se com outros estudos feitos em serragem. As arenas foram dividas em 72 setores iguais a partir do centro de dispersão para facilitar a localização das pupas no substrato. A massa, a distância de dispersão do centro de arena, e a profundidade de cada pupa foram determinadas e verificou-se a relação entre peso, profundidade e distância do centro de dispersão. Pôde-se constatar que as larvas com menor massa foram as que percorreram maior distância do centro de dispersão, como também foi observado em estudos anteriores que empregaram outros substratos. O sítio de pupação da maioria dos indivíduos foi entre 2 e 8 cm de profundidade (média 4,96±2,97 cm). Tal estudo do processo de dispersão pode ser útil na estimativa do intervalo pós-morte (IPM) para corpos humanos em investigações médico-criminais.

Dispersão larval pós-alimentar de Lucilia sericata (Diptera, Calliphoridae) em condições de laboratório

Os dípteros califorídeos são os primeiros indivíduos a compor a sucessão faunística de cadáveres em decomposição, auxiliando assim na estimativa do intervalo pós-morte. Estudos de dispersão pós-alimentar de suas larvas possuem relevância para investigações médico-criminais. Diante disto, uma arena circular, simulando o ambiente natural, foi montada em laboratório a fim de verificar-se a dispersão larval radial pós-alimentar de Lucilia sericata (Meigen, 1826), tentando assim estabelecer relações entre as variáveis peso, distância e profundidade de enterramento na arena. Os resultados demonstraram que 45% das pupas foram recuperadas a uma profundidade compreendida entre 6 cm e 8 cm e a uma distância entre 33 cm e 45 cm do centro da arena. Não houve diferenças significativas quanto à propagação e profundidade de enterramento de machos, fêmeas e indivíduos inviáveis. Com relação ao peso, verificou-se que a média das fêmeas (x = 32,35 mg) foi superior a dos machos (x = 30,28 mg). A análise de correlação e de regressão entre peso e distância percorrida e entre peso e profundidade foram positivas, ou seja, pupas oriundas de larvas mais pesadas propagaram e se aprofundaram mais. O experimento permitiu ainda concluir que uma arena circular possibilita o deslocamento das larvas em todas as direções.
