Guia politicamente incorreto da história do Brasil.

Os problemas envolvidos na classificação e na padronização da vida social têm sido alvo de minhas preocupações de estudo há quase uma década. De fato, venho escrevendo um livro sobre esse assunto. Nele, a classificação e a padronização são discutidas dentro de contextos interativos que ressaltam suas características de automatismo, de hábito, de reprodução de valores e de comportamento. Classificar é seguir uma regra adrede preparada no intuito de oferecer coerência a um corpo de ideias, buscando fortalecê‑lo. Para se ter um breve exemplo da importância e das implicações da classificação na vida social, basta lembrar alguns acontecimentos dos séculos 17 e 18 com relação aos estudos dos naturalistas. Sabe-se que, naquele período, a dominação europeia sobre a América carecia de uma teoria científica (classificatória) que desse fundamentos lógicos e empíricos à supremacia europeia pela inevitável ?demonstração? da inferioridade do Novo Mundo. Toda a diversa paisagem natural da América foi alvo desse veículo classificatório: seu ar, seu clima, seus pântanos, seus habitantes, seus animais, sua vegetação, suas terras, suas montanhas, seus vulcões.Obra resenhada: NARLOCH, Leandro.

Delaying the timing of offshoring low-skilled tasks

WOS:000281106500009 (Nº de Acesso Web of Science)This paper examines the impact of uncertainty on offshoring low-skilled tasks. The model shows that greater demand uncertainty adversely affects the expected profit and timing of offshoring. It is also shown that a home-country tax rate deduction increases the volatility of the expected profits, making offshoring appear to be more risky. One policy implication of our results is that, in order to delay relocation of MNE's production from the home country, a government should adopt tax rate deduction rather than a direct subsidy because the former is more economical and effective than the latter

Spin configurations in hard-soft coupled bilayer systems: from rigid magnet to exchange spring transitions

We investigate equilibrium properties of an exchange-spring magnetic system constituted of a soft layer (e.g. Fe) of a given thickness on top of a hard magnetic layer (e.g. FePt). The magnetization profile M(z) as a function of the atomic position ranging from the bottom of the hard layer to the top of the soft layer is obtained in two cases with regard to the hard layer: i) in the case of a rigid interface (the FePt layer is a single layer), the profile is obtained analytically as the exact solution of a sine-Gordon equation with Cauchy's boundary conditions. Additional numerical simulations also confirm this result. Asymptotic expressions of M(z) show a linear behavior near the bottom and the top of the soft layer. In addition, a critical value of the number of atomic planes in the soft layer, that is necessary for the onset of spin deviations, is obtained in terms of the anisotropy and exchange coupling between the adjacent plane in the soft layer. ii) in the case of a relaxed interface (the FePt layer is a multilayer), the magnetization profile is obtained numerically for various Fe and FePt films thicknesses and applied field.Comment: 10 pages, 9 figures, PRB submitted (12-07-2010

The multidimensional role of social entrepreneurship: A case study approach within an international project context

Social entrepreneurship creates social value and has a multidimensional impact (e.g. economic, environmental, cultural). This is related to the complexity and multidimensional approaches to current societal problems such as climatic changes and socioeconomic crises. The paper explores this multidimensionality by presenting three Portuguese case studies of social entrepreneurship operating in diverse domains. The study is based on primary and secondary data on the selected social enterprises. The analysis explores the motivations and constraints in forming a social enterprise and the impact of entrepreneurial activity. There is evidence of multiple roles played by these entrepreneurial agents, and, therefore, their critical role in the response to the problems that current societies face.info:eu-repo/semantics/publishedVersio
