Climate change and economic growth: a heterogeneous panel data approach.

Climate change is a global phenomenon. Its impact on economic growth must therefore be analyzed in accordance with its (time-varying) common effects. We present an econometric analysis that evaluates this effect taking into account its global nature. Contrary to previous evidence that ignores the global effects, we obtain that the rising temperature has not decreased growth in real GDP per capita in the second half of the twentieth century for the world countries. However, we obtain a negative effect of rising temperatures and a positive effect of rising precipitation in poor countries. This positive effect of rising precipitation is also confirmed for hot and temperate countries.

O cultural e o político no coletivo hip hop chama: um papo reto sobre participação política e relações entre universidade e movimentos sociais / The cultural and the political in the collective hip hop chama a straight chat on political participation and relationship between university and social movements

Este artigo é fruto de pesquisa coletiva realizada pelo Programa Conexões de Saberes na UFMG sobre as mudanças na relação entre pesquisadores e os movimentos sociais com base na crítica à hierarquia de saberes. Realizamos uma pesquisa-intervenção junto ao Coletivo Hip Hop Chama, organização político-cultural voltada para ações educativas com a juventude da região metropolitana de Belo Horizonte. Analisamos as formas de organização e práticas do Coletivo e a construção de identidade coletiva de seus integrantes, a fim de contribuir para o entendimento das formas diversas de participação política. A atuação do grupo não pode ser apreendida se separarmos as instâncias da participação política da produção cultural. Na relação pesquisador/campo constatamos a persistência de uma hierarquia de saberes com predomínio da ciência e a invisibilidade das temáticas enfrentadas pelo Coletivo na Universidade e nas formas de produção de conhecimento.

This article results from a collective research conducted by the “Programa Conexões de Saberes”, at the Federal University of Minas Gerais, about the relationship between researchers and social movements, based on the criticism of the hierarchy of knowledge. We conducted an action-research with the Coletivo Hip Hop Chama, a cultural-political organization that promotes culture and education for the youth in the metropolitan area of Belo Horizonte. We studied the organization and community practices of the Coletivo and the construction of the collective identity of its members, aiming to the understanding of the varied forms of political participation. The experience of the Coletivo points to the construction of a collective identity that rearranges the cultural and political dimensions of their political participation. The researcher-field relation reveals the persistence of a hierarchy of knowledge with the predominance of science, and the invisibility of issues faced by the Coletivo both at the University and in other sources of knowledge production.

Risk factors for dementia in a rural area of Northeastern Brazil.

OBJECTIVE: To identify risk factors for dementia among the elderly in a rural area of Northeastern Brazil. METHOD: The subjects assessed were all 60 years old or older, and lived in a rural region of Bahia, a Northeastern State of Brazil. CAMDEX, a structured clinical evaluation protocol, was used for diagnosis, and applied at the home of the subjects. RESULTS: The risk factors identified were divided in accordance with socio-demographic characteristics, the presence of co-morbid conditions, and the use of medications. The variables with strong association with dementia were age, history of stroke, arterial hypertension, and sight impairment. CONCLUSION: Advanced age, arterial hypertension, and vascular brain injury were the main risk factors associated with dementia, which suggests that public health measures adopted to prevent and control modifiable risk factors can mitigate the prevalence of high rates of dementia.

OBJETIVO: Identificar fatores de risco para demência entre idosos de uma área rural do nordeste do Brasil. MÉTODO: Os indivíduos avaliados tinham 60 anos ou mais e viviam numa região rural na Bahia, Estado do nordeste brasileiro. Um protocolo de avaliação clínica estruturada - CAMDEX - foi utilizado para diagnóstico e aplicado no domicílio dos indivíduos participantes. RESULTADOS: Os fatores de risco identificados foram divididos de acordo com características sócio-demográficas, a presença de comorbidades e o uso de medicações. As variáveis com forte associação para demência foram idade, história de acidente vascular encefálico, hipertensão arterial e comprometimento visual. CONCLUSÃO: Idade avançada, hipertensão arterial e lesão vascular cerebral foram os principais fatores de risco associados com demência, o que sugere que medidas de saúde pública adotadas para prevenir e controlar fatores de risco modificáveis podem diminuir a prevalência de altas taxas de demência.
