As teorias e políticas de desenvolvimento regional sofreram grandes alterações nas duas últimas décadas. Os factores que impulsionam o crescimento económico sustentado já não se relacionam apenas com o capital físico, nem sequer com o capital humano regional. As novas condições de competitividade enfatizam a importância do “capital social”, normas e regras sociais, formais ou informais que promovem a compreensão recíproca e a confiança mútuas entre os agentes da economia da região. Este artigo demonstra a forma como as instituições de uma região se podem organizar em torno dos processos de reestruturação produtiva e encorajar as empresas na região a adoptar normas, expectativas, valores, atitudes e práticas comuns, em suma, uma cultura comum de inovação reforçada pelo processo de aprendizagem social. A acção política dinamizada pela autarquia da Covilhã no projecto ReADAPT, a acção da Associação Nacional dos Industriais de Lanifícios ao promover as condições que sustentam e levam ao aparecimento de redes ou agrupamentos de empresas com actividades relacionadas nas áreas de maior potencial de desenvolvimento da região, e o estabelecimento de relações entre essas redes e as restantes instituições (centros de formação, universidade, sindicatos, etc.) constituem o chamado Sistema Regional de Inovação deste território. Num contexto de depressão económica sectorial e regional, o papel da ANIL e das restantes entidades parceiras assumiu-se como de “animadores e facilitadores” do desenvolvimento. A aprendizagem e a reflexão institucional conseguidas contribuíram também para o que ANIL e as restantes entidades parceiras e o sector público com o qual interagem, tenham adquirido uma nova capacidade de inovação estratégica. Neste contexto, instituições de carácter regional/local assumem-se como um elemento essencial na construção de racionalidades e no condicionamento de comportamentos reflexivos e de cooperação, indicando os caminhos possíveis a seguir aos restantes actores da região. Em suma, as dinâmicas de associação entre actores regionais são um ingrediente fundamental na receita para o desenvolvimento das regiões, no sentido em que podem ajudar outros a ajudar-se na criação de significados, na construção de capacidade para agir e no suporte à construção de redes através das quais os agentes económicos e sociais podem colaborar em benefício comum.

Background. Teachers’ legitimacy is central to school functioning. Teachers’ justice, whether distributive or procedural, predicts teachers’ legitimacy. Aims. What is still do be found, and constitutes the goal of this paper, is whether unjust treatment by a teacher affects the legitimacy of the teacher differently when the student knows that the teacher was fair to a peer (comparative judgement) or when the student does not have that information (autonomous judgement). Samples. A total of 79 high school students participated in Study 1; 75 high school students participated in Study 2. Methods. Two experimental studies with a 2 justice valence (just, unjust) 9 2 social comparison processes (autonomous judgements, comparative judgements) betweenparticipants design were conducted. Study 1 addressed distributive justice and Study 2 addressed procedural justice. The dependent variable was teachers’ legitimacy. Results. In both studies, situations perceived as just led to higher teachers’ legitimacy than situations perceived as unjust. For the distributive injustice conditions, teachers’ legitimacy was equally lower for autonomous judgement and comparative judgement conditions. For procedural injustice, teachers’ legitimacy was lower when the peer was treated justly and the participant was treated unfairly, compared with the condition when the participants did not know how the teacher treated the peer. Conclusions. We conclude that teachers’ injustice affects teachers’ legitimacy, but it does it differently according to the social comparisons involved and the type of justice involved. Moreover, these results highlight that social comparisons are an important psychological process and, therefore, they should be taken into account in models of justice.

Adults of most marine benthic and demersal fish are site-attached, with the dispersal of their larval stages ensuring connectivity among populations. In this study we aimed to infer spatial and temporal variation in population connectivity and dispersal of a marine fish species, using genetic tools and comparing these with oceanographic transport. We focused on an intertidal rocky reef fish species, the shore clingfish Lepadogaster lepadogaster, along the southwest Iberian Peninsula, in 2011 and 2012. We predicted high levels of self-recruitment and distinct populations, due to short pelagic larval duration and because all its developmental stages have previously been found near adult habitats. Genetic analyses based on microsatellites countered our prediction and a biophysical dispersal model showed that oceanographic transport was a good explanation for the patterns observed. Adult sub-populations separated by up to 300 km of coastline displayed no genetic differentiation, revealing a single connected population with larvae potentially dispersing long distances over hundreds of km. Despite this, parentage analysis performed on recruits from one focal site within the Marine Park of Arrábida (Portugal), revealed self-recruitment levels of 2.5% and 7.7% in 2011 and 2012, respectively, suggesting that both long- and short-distance dispersal play an important role in the replenishment of these populations. Population differentiation and patterns of dispersal, which were highly variable between years, could be linked to the variability inherent in local oceanographic processes. Overall, our measures of connectivity based on genetic and oceanographic data highlight the relevance of long-distance dispersal in determining the degree of connectivity, even in species with short pelagic larval durations.
