Free Movement of Persons: The Mirage of Social Security Schemes. Bruges European Economic Research Papers (BEER) 34/2015

The purpose of this paper is to address the issue of social security benefits that jobseekers, nationals of other Member State, residing in another Member States are in title to, as well as the economic implications of free movement of persons and labour market access. Consequently, it aims to disentangle between labour mobility welfare effects and “benefit tourism” looking in particular at the United Kingdom social security system and analysing the policy framework currently in place that governs the free movement of people across the European Union Member States.

Neurogenomic mechanisms of social plasticity

Group-living animals must adjust the expression of their social behaviour to changes in their social environment and to transitions between life-history stages, and this social plasticity can be seen as an adaptive trait that can be under positive selection when changes in the environment outpace the rate of genetic evolutionary change. Here, we propose a conceptual framework for understanding the neuromolecular mechanisms of social plasticity. According to this framework, social plasticity is achieved by rewiring or by biochemically switching nodes of a neural network underlying social behaviour in response to perceived social information. Therefore, at the molecular level, it depends on the social regulation of gene expression, so that different genomic and epigenetic states of this brain network correspond to different behavioural states, and the switches between states are orchestrated by signalling pathways that interface the social environment and the genotype. Different types of social plasticity can be recognized based on the observed patterns of inter- versus intra-individual occurrence, time scale and reversibility. It is proposed that these different types of social plasticity rely on different proximate mechanisms at the physiological, neural and genomic level.

A inserção profissional de assistentes sociais em instituições particulares de solidariedade social com resposta à senioridade: o caso do concelho da Covilhã

O presente trabalho teve como objetivo analisar a inserção das Técnicas de Serviço Social na área da senioridade. Como se trata de um estudo de caso restringe-se concelho da Covilhã. Por isso, foi realizado um estudo que tinha quatro vertentes: as Assistentes Sociais, as Instituições Particulares de Solidariedade Social e o concelho da Covilhã. No sentido de tomar mais consistente a pesquisa, foi desenvolvido um guião de entrevista e aplicado a várias profissionais inseridas nas Ipss com três valências (ERPI, SAD e CD) no concelho. Posteriormente foram analisados os resultados e comparados com dados recolhidos dos Censos, do Instituto nacional de Estatística e Pordata. O tema é bastante atual e pertinente, devido ao panorama nacional. Por um lado o aumento da Taxas de desemprego e emigração, e por outro o envelhecimento da população e o aumento dos casos sociais. Concluiu-se que, para as entrevistadas a maior dificuldade no desempenho das suas funções é a excessiva carga horária, os problemas diários associados aos idosos (Dependência física e mental, o Luto, condições desumanas) no entanto revelaram alguma facilidade e rapidez na obtenção do primeiro emprego.

The Principle of Common Concern and Climate Change

Effective policies combating global warming and incentivising reduction of greenhouse gases face fundamental collective action problems. States defending short term interests avoid international commitments and seek to benefit from measures combating global warming taken elsewhere. The paper explores the potential of Common Concern as an emerging principle of international law, in particular international environmental law, in addressing collective action problems and the global commons. It expounds the contours of the principle, its relationship to common heritage of mankind, to shared and differentiated responsibility and to public goods. It explores its potential to provide the foundations not only for international cooperation, but also to justify, and delimitate at the same time, unilateral action at home and deploying extraterritorial effects in addressing the challenges of global warming and climate change mitigation. As unilateral measures mainly translate into measures of trade policy, the principle of Common Concern is inherently linked and limited by existing legal disciplines in particular of the law of the World Trade Organization.

Human Capital and New Venture Performance: The Moderating Role of Social Relations

With whom should entrepreneurs create their firms in order to enhance nascent venture performance? Conventional wisdom suggests that the stronger human capital and social relations in nascent venture teams are, the better the nascent venture’s performance. We draw from social embeddedness literature, however, and argue that the positive effect of team members’ human capital on three different dimensions of nascent venture performance is weaker when team members exhibit strong social relations. Our analysis of 488 nascent venture teams in the PSED II dataset confirms our predictions, showing that nascent ventures of teams with strong human capital but weaker social relations exhibit the best performance. The study thus offers valuable contributions particularly to literature on entrepreneurial teams the determinants of new venture performance.
