Communication challenges for partner organisations

Many people not directly involved in developing, maintaining and evaluating business–community partnerships tend to assume that such partnerships are one of two types: an add-on to an organisation’s core business or a fundraiser for an NGO. There are lots of examples of these two categories of “partnership” around the world, but there are considerably fewer of a third type – where the partnership is part of “core business” and as such is deeply embedded in the more forward-looking companies and community organisations that implement them, and also achieves significant internal impact. This situation raises some interesting communication
challenges.

Ni2+-based immobilized metal ion affinity chromatography of lactose operon repressor protein from Escherichia coli

A two-step chromatographic sequence is described for the purification of native lactose operon repressor protein from Escherichia coli cells. The first step involves Ni2+-based immobilized metal ion affinity chromatography of the soluble cytoplasmic extract. This method provides superior speed, resolution and yield than the established phosphocellulose cation-exchange chromatographic procedure. Anion-exchange chromatography is used for further purification to >95% purity. The identity and purity of the lactose repressor protein were demonstrated using sodium dodecylsulphate polyacrylamide electrophoresis, crystallization, tryptic finger-printing mass spectrometry, and inducer binding assays. The purified lac repressor exhibited inducer sensitivity for operator DNA binding and undergoes a conformational change upon inducer binding. By all these extensive biochemical criteria, the purified protein behaves exactly as that described for the Escherichia coli lactose operon repressor.

Special interests and political business cycles

In this paper we bridge the gap between special interest politics and political business cycle literature. We build a framework where the interplay between the lobby power of special interest groups and the voting power of the majority of the population leads to political business cycles. We apply our set up to explain electoral cycles in government expenditure composition, aggregate expenditures and real exchange rates.

Sources of comparative advantages in Brazil

Based on the Heckscher-Ohlin-Vanek model, this paper investigates relative factor abundance in Brazil, as revealed by its international trade. We study two different time periods: one characterized by high trade barriers (1980 to 1985) and the trade liberalization period (1990 to 1995). Two alternative methodologies are used: the estimation of factor intensity regressions on net exports and the direct computation of factor content in net exports. In the factor intensity regression, we incorporate technological changes that might have occurred over time, and those turned out to be significant. Both methods yield the same results: the Brazilian international trade reveals relative abundance in capital, land and unskilled labor, and scarcity in skilled labor, with qualitatively equivalent results for the two time periods studied.

The political economy of exchange rate in Brazil

This paper reviews part of the political economy literature on exchange rate policy relevant to understanding the political motivations behind the Brazilian exchange rate policy. We shall first examine the distributive role of the exchange rate, and the way it unfolds in terms of the desired political goals. We will follow by analyzing exchange policy as indicative of government effciency prior to elections. Finally, we discuss fiscal policy from the point of view of political economy, in which the exchange rate results from the macroeconomic equilibrium. Over this review, the Brazilian exchange rate policy is discussed in light of the theories presented.

Com a palavra mate com angu: uma intervenção estética no município de Duque de Caxias

Nas sociedades contemporâneas a cidadania cultural é um tema a ser enfrentado ao lado da defesa por uma melhor qualidade de vida material, ambiental, econômica e social. Assim, o direito à liberdade de criação, informação, expressão da diversidade entre outros, apresentam-se como desafios e fundamentos para uma verdadeira democracia cultural.O presente trabalho encontra-se inserido no campo dos estudos de novas práticas de cidadania exercidas particularmente por movimentos culturais. Nosso objeto de pesquisa foi o cineclube Mate com Angu, localizado na Baixada Fluminense.Por meio de entrevistas temáticas, buscamos aferir como cinco integrantes do grupo formulam e realizam sua proposta de intervenção social e estética, e interagem com sua comunidade Duque de Caxias utilizando a linguagem audiovisual.Os argumentos e as práticas do Mate com Angu revelaram que embora o compromisso central do grupo seja no campo estético, suas atividades trazem implicações também nos campos político e social, influenciando a vida e a cultura da comunidade caxiense. Desse modo constatamos que suas intervenções contribuem para a ampliação do conceito de cidadania, e particularmente para a construção dos direitos culturais.
