This paper studies the relations between bilateral FDIs and immigrant networks of France, Germany, UK, Italy and Spain, and the emigrant diasporas of Italy and Spain. It focuses on skilled and unskilled immigrants and on ties with developing and developed countries. Results evidence two different network models: FDIs of UK, Germany and France are prompted by the ties of skilled immigrants, while those of Italy and Spain are only influenced by their respective diasporas. The disparity may stem from history. Differently from the findings of previous literature, the effects of networks with developing countries are similar to those with rich economies.  相似文献

Insulin-like growth factor 1 (IGF-1) signaling modulation has been associated with increased lifespan in model organisms, while high levels of circulating interleukin-6 (IL-6) are a marker of disability and mortality. In the prospective, population-based "Treviso Longeva"--TRELONG Study from Italy (n = 668, age range 70-105.5 years at baseline, followed for seven years) we investigated the effects of survival on the IGF-1 receptor (IGF-1R) gene polymorphism rs2229765, the IL-6 gene promoter polymorphism rs1800795, and plasma concentrations of IGF-1 and IL-6, alone or in combination. We found a sex-dependent effect for the IGF-1R rs2229765 polymorphism, as male carriers of the homozygous A/A genotype survived longer, while the IL-6 rs1800795 genotype did not influence overall or sex-specific longevity. Higher IL-6 levels were more detrimental for survival among males than females, while IGF-1 had no dose-response effect. These findings sustain the hypothesis that sex-specific longevity relies on detectable differences in genetic and biochemical parameters between males and females.  相似文献

The Black Adoption Research and Placement Center is a nonprofit organization delivering culturally specific adoption and foster care services. The organization developed as a response to concerns in the African-American community about the high numbers of African-American children entering and not exiting the public foster care system. The organization has undergone significant transformations over its 25-year history in relation to social, political, and economic changes that have altered the ways that the agency finances and delivers services. The history of Black Adoption Research and Placement Center presents an organization that has weathered many challenges because of its strong leadership, its committed governing body, its external relationships, and its internal operations.  相似文献

Research into workplace bullying has continued to grow and mature since emerging from Scandinavian investigations into school bullying in the late 1970s. Research communities now exist well beyond Scandinavia, including Europe, the UK, Australia, Asia and the USA. While the terms ‘harassment’ and ‘mobbing’ are often used to describe bullying behaviour, ‘workplace bullying’ tends to be the most consistently used term throughout the research community. In the past two decades especially, researchers have made considerable advances in developing conceptual clarity, frameworks and theoretical explanations that help explain and address this very complex, but often oversimplified and misunderstood, phenomenon. Indeed, as a phenomenon, workplace bullying is now better understood with reasonably consistent research findings in relation to its prevalence; its negative effects on targets, bystanders and organizational effectiveness; and some of its likely antecedents. However, as highlighted in this review, many challenges remain, particularly in relation to its theoretical foundations and efficacy of prevention and management strategies. Drawing on Affective Events Theory, this review advances understanding through the development of a new conceptual model and analysis of its interrelated components, which explain the dynamic and complex nature of workplace bullying and emphasize current and future debates. Gaps in the literature and future research directions are discussed, including the vexing problem of developing an agreed definition of workplace bullying among the research community, the emergence of cyberbullying, the importance of bystanders in addressing the phenomenon and the use of both formal and informal approaches to prevention and intervention.  相似文献

Pathways to Prevention is an early prevention project founded on developmental systems theory operating through a schools‐community agency‐university partnership in a socially disadvantaged area of Brisbane. Circles of Care is a Pathways programme also implemented on a small scale by the same agency in a regional city. The Circles programme is designed to strengthen connections between schools, families and community services, and harmonize activities in these settings by surrounding children with identified needs with a supportive group of adults. A Circle, which includes at least the child, parent(s), teacher and agency staff, sets goals, mobilizes resources for the child, family and school, and monitors progress. The client is conceptualized not as the child but as a dysfunctional developmental system, with better outcomes for children as the ultimate goal. Qualitative evaluation at the two sites showed that while Circles worked well at the level of practical support and relationship building and did achieve good child outcomes, its capacity to achieve collaborative practice and strengthen system relations was limited by entrenched organizational structures and cultures. However, one site, with more support for collaboration across organizational boundaries, suggested that system alignment is achievable on a larger scale with vision and leadership for organizational reform.  相似文献

ABSTRACT

This article describes a framework for measuring activity demands and the psychometric properties of a related measurement tool, the Multidimensional Activities Demand Strength for Assisted Living (MADS-AL). Nine experts—three in physical, cognitive, and social domains, respectively—rated demands of 37 common assisted-living activities. Interrater reliability and internal consistency for physical, intraclass correlation coefficient (ICC)(2, 3) = .96, Cronbach's α = .97, cognitive, ICC(2, 3) = .71, α = .93, and social, ICC(2, 3) = .80, α = .86, scales give preliminary support for reliability of the MADS-AL tool. Overall, this article moves the field toward considering task demands as a relevant variable to inform future activities research and practice.  相似文献

This paper deals with the influence of friends in class on adolescents’ problematic school behavior (i.e. inattention in class and not doing homework). We examine whether this influence is moderated by ego (i.e. the adolescent's indegree), alter (i.e. friends’ indegree) and dyadic characteristics (i.e. friendship reciprocity). Influence processes are analyzed with a stochastic actor-based model (SIENA), while controlling for friendship selection. Using a 4-wave panel dataset, we find that friends influence adolescents’ problematic school behavior. Adolescents with a higher indegree are less likely to be influenced. The influence of friends is not significantly moderated by friends’ indegree and friendship reciprocity.  相似文献

ABSTRACT

Many college students today are no longer using the terms straight, gay, lesbian, bisexual, or transgender to self-identify their sexual orientation or gender identity. This commentary explores research related to fluidity of sexual identities, emerging sexual identities used by college students, and how these identities interact with the health and well-being of the student. Additionally, the authors discuss strategies to help college health professionals provide a sensitive environment and clinical experience for students whose sexual identity is fluid.  相似文献
