Fundamentos para uma pol??tica de carreiras no contexto da reforma gerencial

Com o advento da administra????o gerencial no ??mbito do aparelho do Estado, em complementa????o ?? administra????o burocr??tica, verifica-se certa turbul??ncia na gest??o de pessoal na administra????o p??blica, decorrente da s??bita aus??ncia de fundamentos conceituais s??lidos que permitam pensar a administra????o do capital humano do Estado em um contexto de transforma????o. Este artigo procura estabelecer as bases para a recupera????o destes fundamentos, propondo tr??s crit??rios de design de carreiras: a estrutura de incentivos, os mecanismos de governan??a e a gest??o do conhecimento. Em seguida, exemplifica-se a utiliza????o destes crit??rios pela an??lise de seis temas pr??prios ?? discuss??o sobre carreiras no servi??o p??blico: remunera????o, sele????o, recrutamento e desenvolvimento, mobilidade, promo????o, carreiras para ag??ncias executivas e controle social da burocracia.

Lead reduces tension development and the myosin ATPase activity of the rat right ventricular myocardium

Lead (Pb2+) poisoning causes hypertension, but little is known regarding its acute effects on cardiac contractility. To evaluate these effects, force was measured in right ventricular strips that were contracting isometrically in 45 male Wistar rats (250-300 g) before and after the addition of increasing concentrations of lead acetate (3, 7, 10, 30, 70, 100, and 300 µM) to the bath. Changes in rate of stimulation (0.1-1.5 Hz), relative potentiation after pauses of 15, 30, and 60 s, effect of Ca2+ concentration (0.62, 1.25, and 2.5 mM), and the effect of isoproterenol (20 ng/mL) were determined before and after the addition of 100 µM Pb2+. Effects on contractile proteins were evaluated after caffeine treatment using tetanic stimulation (10 Hz) and measuring the activity of the myosin ATPase. Pb2+ produced concentration-dependent force reduction, significant at concentrations greater than 30 µM. The force developed in response to increasing rates of stimulation became smaller at 0.5 and 0.8 Hz. Relative potentiation increased after 100 µM Pb2+ treatment. Extracellular Ca2+ increment and isoproterenol administration increased force development but after 100 µM Pb2+ treatment the force was significantly reduced suggesting an effect of the metal on the sarcolemmal Ca2+ influx. Concentration of 100 µM Pb2+ also reduced the peak and plateau force of tetanic contractions and reduced the activity of the myosin ATPase. Results showed that acute Pb2+ administration, although not affecting the sarcoplasmic reticulum activity, produces a concentration-dependent negative inotropic effect and reduces myosin ATPase activity. Results suggest that acute lead administration reduced myocardial contractility by reducing sarcolemmal calcium influx and the myosin ATPase activity. These results also suggest that lead exposure is hazardous and has toxicological consequences affecting cardiac muscle.

Estudo sobre a captação dos fundos de Private Equity e Venture Capital

O estudo tem por objetivo avaliar os fatores que possam explicar a captação de recursos (fundraising) dos fundos de Private Equity e Venture Capital (PE/VC). Em linhas gerais, a proposta é averiguar empiricamente quais são os fatores que impactam na captação de recursos pelos fundos de PE/VC. A amostra foi formada por 25 países e em um espaço temporal de 6 anos (2006-2011). Foram identificados seis fatores: atividade econômica, desenvolvimento do mercado de capitais, governança corporativa, desenvolvimento socioambiental, empreendedorismo e tributação. Assim, construiu-se através de Análise Fatorial seis fatores que foram compostos por 26 variáveis. Por meio de regressão múltipla foram investigadas as relações entre a captação de recursos por parte dos fundos PE/VC e os fatores gerados. Os resultados demonstraram que apesar dos fatores testados serem significativos, a captação dos recursos é fortemente influenciada pelo nível de desenvolvimento do mercado de capitais. Os resultados aqui encontrados se tornam relevantes, pois discutem uma realidade crescente tanto no Brasil quanto no mundo, visto que o mercado de PE/VC solidifica-se como alternativa de captação de recursos.

Há salvação para a África? Thabo Mbeki e seu New Partnership for African development

O NEPAD - New Partnership for African Development - tem seus primórdios em 1996, proposto pelo atual presidente da África do Sul, Thabo Mbeki e outros líderes africanos, para erradicar a marginalização e o subdesenvolvimento africanos e promover o crescimento econômico, através da integração continental. Seus objetivos, inseridos no contexto da globalização e do African Renaissance, incorpora valores da luta antiapartheid sul-africana, restauração da auto-estima e resgate de valores pré-coloniais. O que o difere de outros planos que não deram certo na África é o vínculo inseparável entre democracia, direitos humanos, paz, governabilidade e o desenvolvimento econômico, as responsabilidades assumidas pelos participantes e a propriedade africana do plano.

When emergent countries reform global governance of climate change: Brazil under Lula

Due to its recent economic success, Brazil is considered an emerging country, but is it an emerging power concerning global environmental governance? This article argues that although Brazil has a sui generis profile, it can only be considered an emerging power in some environmental regimes, such as global climate change. Thus, international relations theory needs more analytical instruments to assess the impact of emerging powers in global environmental governance

The G-77, BASIC, and global climate governance: a new era in multilateral environmental negotiations

The G-77 has historically organized the participation of developing countries in multilateral environmental negotiations. This article analyses the impact of a new coalition of emerging powers - Brazil, China, India, and South Africa as BASIC - on the G-77's role in climate governance. While there are important benefits for both sides in their relationship, I argue that the G-77 is also disadvantaged in several concrete ways by the BASIC countries.

The contribution of the European Union to global climate change governance: explaining the conditions for EU actorness

Como organização regional, o papel da União Europeia na governança global do clima enfrenta obstáculos que não se aplicam a nenhuma outra parte da Convenção-Quadro das Nações Unidas sobre a Mudança do Clima (CQNUMC) e do Protocolo de Quioto. Avaliando essa singularidade, este artigo fornece uma analise teórica e empírica de como os elementos de actorness (reconhecimento, capacidade, oportunidade e coesão) definem a participação da UE no regime internacional de mudanças climáticas.

Governance of global climate change in the Brazilian Amazon: the case of Amazonian municipalities of Brazil

With regards to the debate about governance of climate change, it should be assumed that the Amazon region plays an important role, as this large area is highly vulnerable to its effects. In this sense, this article aims to discuss how some Amazonian municipalities of Brazil have been taking part in the complexes and multilayered processes of climate governance.

An outline of military technological dynamics as restraints for acquisition, international cooperation and domestic technological development

The expectation that technological returns from defense expenditure through acquisition, international cooperation and domestic research would further national development underappreciates the different technological dynamic of the armed services. This paper outlines the technological dynamic the stems from fighting in the air, at sea and on land, exemplifying consequences for the case of acquisition.

Multi-level governance and social cohesion in the European Union: the assessment of local agents, a study case inside Galicia

Implementing multi-level governance has been a key priority in EU cohesion policy. This study assesses the perceived achievements and shortcomings in implementing European Social Fund by analyzing the deficits and weaknesses as well as the poor participation of local agents who are in direct contact with the beneficiaries in order to design and implement this fund, which is the main financial instrument of EU social policy.
