Este artigo busca entender como a parceria entre as organizações locais (associações, cooperativas, sindicatos dos trabalhadores e outros) e o governo contribui para o desenvolvimento local. O artigo explora em que medida a parceria é uma estratégia efetiva para o desenvolvimento local em áreas historicamente marcadas por conflito entre os governos municipais e as organizações locais que defendem os interesses dos pequenos produtores rurais de base familiar. Particularmente, o artigo se concentra na discussão sobre a parceria como um mecanismo de divisão de poder e empoderamento das pessoas que historicamente têm sido excluÃdas do processo de desenvolvimento local. Os dados empÃricos do artigo foram coletados nos municÃpios de Ourém e Igarapé-Miri, Nordeste do Pará, Amazônia, Brasil.

Neste artigo analisamos a literatura de parceria entre o estado e a sociedade civil, em particular sobre a parceria entre as organizações públicas e as organizações sem fins lucrativos. Discutimos as diferentes perspectivas do conceito de parceria e objetivamos destacar algumas das principais preocupações teóricas sobre este conceito no contexto da governança. Buscamos mostrar que, em geral, o contexto histórico da parceria não tem sido incluÃdo entre os fatores usados para explicar o seu uso no contexto da governança. Apontamos que, a despeito das análises sobre parceria que indicam que esta traz benefÃcios sociais, ainda existem lacunas no conhecimento que evidenciem que esta "tecnologia social" contribui efetivamente para empoderar as pessoas e os grupos sociais com menor poder de influência. A maior parte da literatura sugere que a parceria objetiva fortalecer a relação entre a população e o governo local e melhorar as possibilidades das pessoas e dos grupos sociais com menor poder de influência em participar na governança local. Entretanto, não encontramos na literatura sobre parceria evidências substantivas de que ela se direciona para modificar a estrutura de poder polÃtico. Finalmente, mostramos que não está claro se a interação entre as "pessoas comuns" e o estado, por via de um processo participativo, tem contribuÃdo efetivamente para construir coesão social para diferentes grupos sociais. A principal contribuição do artigo é expandir o conhecimento dos fatores que influenciam (de forma positiva e negativa) o processo de parceria entre o estado e a sociedade civil para o desenvolvimento local.

The electronic and structural properties and elastic constants of the wurtzite phase of GaN, was investigated by computer simulation at Density Functional Theory level, with B3LYP and B3PW hybrid functional. The electronic properties were investigated through the analysis of the band structures and density of states, and the mechanical properties were studied through the calculus of the elastic constants: C11, C33, C44, C12, and C13. The results show that the maximum of the valence band and the minimum of the conduction band are both located at the Γ point, indicating that GaN is a direct band gap semiconductor. The following constants were obtained for B3LYP and B3PW (in brackets): C11 = 366.9 [372.4], C33 = 390.9 [393.4], C44 = 99.1 [96.9], C12 = 143.6 [155.2], and C13 = 107.6 [121.4].

The respiration of metal oxides by the bacterium Geobacter sulfurreducens requires the assembly of a small peptide (the GS pilin) into conductive filaments termed pili. We gained insights into the contribution of the GS pilin to the pilus conductivity by developing a homology model and performing molecular dynamics simulations of the pilin peptide in vacuo and in solution. The results were consistent with a predominantly helical peptide containing the conserved a-helix region required for pilin assembly but carrying a short carboxy-terminal random-coiled segment rather than the large globular head of other bacterial pilins. The electronic structure of the pain was also explored from first principles and revealed a biphasic charge distribution along the pilin and a low electronic HOMO-LUMO gap, even in a wet environment. The low electronic band gap was the result of strong electrostatic fields generated by the alignment of the peptide bond dipoles in the pilin's alpha-helix and by charges from ions in solution and amino acids in the protein. The electronic structure also revealed some level of orbital delocalization in regions of the pilin containing aromatic amino acids and in spatial regions of high resonance where the HOMO and LUMO states are, which could provide an optimal environment for the hopping of electrons under thermal fluctuations. Hence, the structural and electronic features of the pilin revealed in these studies support the notion of a pilin peptide environment optimized for electron conduction.

The magnetic properties of Mn nanostructures on the Fe(001) surface have been studied using the noncollinear first-principles real space-linear muffin-tin orbital-atomic sphere approximation method within density-functional theory. We have considered a variety of nanostructures such as adsorbed wires, pyramids, and flat and intermixed clusters of sizes varying from two to nine atoms. Our calculations of interatomic exchange interactions reveal the long-range nature of exchange interactions between Mn-Mn and Mn-Fe atoms. We have found that the strong dependence of these interactions on the local environment, the magnetic frustration, and the effect of spin-orbit coupling lead to the possibility of realizing complex noncollinear magnetic structures such as helical spin spiral and half-skyrmion.

Too Big to Ignore (TBTI; www.toobigtoignore.net) is a research network and knowledge mobilization partnership established to elevate the profile of small-scale fisheries (SSF), to argue against their marginalization in national and international policies, and to develop research and governance capacity to address global fisheries challenges. Network participants and partners are conducting global and comparative analyses, as well as in-depth studies of SSF in the context of local complexity and dynamics, along with a thorough examination of governance challenges, to encourage careful consideration of this sector in local, regional and global policy arenas. Comprising 15 partners and 62 researchers from 27 countries, TBTI conducts activities in five regions of the world. In Latin America and the Caribbean (LAC) region, we are taking a participative approach to investigate and promote stewardship and self-governance in SSF, seeking best practices and success stories that could be replicated elsewhere. As well, the region will focus to promote sustainable livelihoods of coastal communities. Key activities include workshops and stakeholder meetings, facilitation of policy dialogue and networking, as well as assessing local capacity needs and training. Currently, LAC members are putting together publications that examine key issues concerning SSF in the region and best practices, with a first focus on ecosystem stewardship. Other planned deliverables include comparative analysis, a regional profile on the top research issues on SSF, and a synthesis of SSF knowledge in LAC
