Rafaela Ganga José Pedro Silva Rui Gomes Henrique Vaz João Teixeira Lopes Sílvia Silva Luísa Cerdeira Belmiro Cabrito Dulce Magalhães Maria de Lurdes Machado‐Taylor Paulo Peixoto Tomás Patrocínio Rui Brites 《International migration (Geneva, Switzerland)》2016,54(6):43-55
In the economic and social aftermath of the 2008 crisis there has been an important and growing new wave of highly qualified Portuguese emigration comprising scientists. No or very few public policies have been designed to reverse this phenomenon, risking the consequences of brain drain. International literature argues that professional reasons are central to scientists’ decision to migrate, even after the 2008 crisis. Spending some time in a foreign country to study, research, or teach, is perceived as a common step in an individual academic trajectory and an advantage for a successful professional career in academia. It is also encouraged by European Union policies. Twelve individual portraits of Portuguese scientists living in central Europe reveal how important other factors are to the migration decision‐making process. These factors include the economic crisis, student mobility programmes, and the current Portuguese scientific system revision. 相似文献

In therapeutic conversations, questions can be considered as interventions in their own right. This study is a cross‐cultural replication of Grant (Journal of Systemic Therapies, 2012, 31, 2, 21) study on the effects of different types of questions on various clinically relevant variables. A total of 204 students of a Spanish university described a real‐life problem that they wanted to solve and were then randomly assigned to either a solution‐focused or a problem‐focused questions condition. Before and after answering the questions, they completed a set of measures that assessed positive and negative affect, self‐efficacy, and goal attainment. Solution‐focused questions produced a significantly greater increase in self‐efficacy, goal approach, and action steps than problem‐focused questions, and a significantly greater decrease in negative affect, providing further empirical support to solution‐focused practices. 相似文献

Comiendo Bien: The Production of Latinidad through the Performance of Healthy Eating among Latino Immigrant Families in San Francisco 下载免费PDF全文
Airín D. Martínez 《Symbolic Interaction》2016,39(1):66-85
Utilizing a bricolage of interactionist cultural studies, ethnic foodways, and situational analysis this paper examines how Latino immigrants, representing six countries and multiple preimmigration class positions, come to perform Latinidad through the lay health practice of comiendo bien (eating well). Comiendo bien was examined through participant observation of 15 families living in San Francisco and 27 key informant interviews. Comiendo bien is a performance that exists through the convergence of multiple identity positions. Latina/o immigrants not only enact the Latinidad in the United States through artistic expression or political strategizing, but also by sharing an idealized practice of healthy eating. 相似文献

This article is an attempt at developing a lens through which political culture in Mozambique can be analysed, described and interpreted. It is based on the notion of a political teleology that emerged out of the conditions within which the country fought for its independence. The paper argues that violence in a symbolic and physical form played a central role in the constitution of this political teleology by, on the one hand, allowing the liberation movement to produce an account of Mozambican history which both gave legitimacy to its own struggle while at the same time undermining alternative accounts and, on the other, set the scene for the implementation of a national project that came to be primarily concerned with the reproduction of the claim to power of the liberation movement. Forty years of independence in Mozambique offer an ideal time frame to attempt the construction of such a lens. 相似文献

It is usually considered that the proportion of handicapped people grows with age. Namely, the older the man/woman, the more the level of disability he/she suffers. However, empirical evidence shows that this assessment is not always true, or at least, it is not true in the Spanish population. The study tries to assess the impact of age on disability in Spain. Each gender has been treated separately because it can be shown that men and women have their own pattern of behaviour. Three different methods of estimation have been used to check the link between those variables. The results seem to support the idea that the relationship among age and the intensity of disability is not always direct. One of the concluding remarks in this analysis is that the method of estimation has a great incidence in the final results, especially in central ages between 20 and 80 years old. 相似文献

The term gridlock describes the occurrence of rigid patterns in couples’ conflict. This study aimed to describe strategies of conflict resolution and gridlock prevention from the perspectives of couples and couple therapists. Participants were couple therapists and highly adjusted couples scored by the dyadic adjustment scale (DAS), distributed according to traditional and non‐traditional position in life and duration of relationships. Conflict gridlock scenarios were used to create video stimulus that were presented to participants. A qualitative methodology was used to analyse couples’ and therapists’ commentaries on the scenarios. Results showed differences in preventing conflict gridlock among sub‐groups of couples. Long‐term traditional couples focused on loyalty to a common project and value sacrificing to a higher good; long‐term non‐traditional couples prioritised caring and validating the bond in the relationship. Short‐term traditional couples focused on mutual love and the relief of hurt while short‐term non‐traditional couples supported the value of equity. 相似文献

Bootstrap procedures are useful to obtain forecast densities for both returns and volatilities in the context of generalized autoregressive conditional heteroscedasticity models. In this paper, we analyse the effect of additive outliers on the finite sample properties of these bootstrap densities and show that, when obtained using maximum likelihood estimates of the parameters and standard filters for the volatilities, they are badly affected with dramatic consequences on the estimation of Value-at-Risk. We propose constructing bootstrap densities for returns and volatilities using a robust parameter estimator based on variance targeting implemented together with an adequate modification of the volatility filter. We show that the performance of the proposed procedure is adequate when compared with available robust alternatives. The results are illustrated with both simulated and real data. 相似文献

Urbanized areas show a high proportion of non-native plants and can work as dispersal points to the surrounding areas. Ensenada
is a fast growing city located in the northwestern peninsula of Baja California (Mexico). It is the southern extreme of a
bi-national, coastal urban corridor that extends from Los Angeles, California south to Ensenada. This corridor is part of
the biodiversity hotspot of the California Floristic Province. The aim of this study was to analyze the composition and distribution
of the spontaneous flora in the city of Ensenada. We systematically sampled two differentiated urban environments, vacant
lots and arroyos, in 2006 and 2007. We found a total of 158 plant species, 61% of them were non-native species. Arroyo areas
showed higher non-native species richness than vacant lots (21.9 vs. 13.6 species/transect) and could be potential dispersal
vectors for non-native species to natural areas outside of the city, or in the reverse direction also. 相似文献

This study uses a regression analysis to explore the cross‐country variation in homicide rates for a large sample of countries. It starts by identifying seven significant regional variables, to which traditional socioeconomic, cultural, and institutional variables are added and tested. The importance of institutions, culture, and other factors affecting homicide rates is discussed. One unexpected finding is a curious relationship between the level of education and homicide rates: while an increase in male education tends to reduce homicide rates, an increase in female education tends to increase homicides. Several possible interpretations for this phenomenon are proposed. The study points to relatively unexplored areas of research in order to better understand homicide variation around the world. 相似文献

This paper calculates a human Wellbeing Composite Index (WCI) for 42 countries, belonging to the European Economic Space, North Africa and the Middle East, as an alternative to the shortcomings of other well-known measures of socio-economic development (i.e. Gross Domestic Product per head and Human Development Index). To attain this goal, different data envelopment analysis (DEA) models are used as an aggregation tool for seven selected socio-economic variables which correspond to the following wellbeing dimensions: income per capita, environmental burden of disease, income inequality, gender gap, education, life expectancy at birth and government effectiveness. The use of DEA allows avoiding the subjectivity that would be involved in the exogenous determination of weights for the variables included in WCI. The aim is to establish a complete ranking of all countries in the sample, using a three-step process, with the last step consisting in the use of a model that combines DEA and compromise programming, and permits to obtain a set of common weights for all countries in the analysis. The results highlight the distance that still separates Southern Mediterranean countries from the benchmark levels established by some European countries, and also point to the main weaknesses in individual countries’ performance. Nordic countries, plus Switzerland, top the list of best performers, while Mauritania, Libya and Syria appear at the bottom. 相似文献
