This paper presents a two-country migration model, following Galor (1986), in which the world population consists of two types individuals. Individuals with a high (low) degree of altruism give to their children a high (low) level of bequest. Production uses three inputs: immobile land, mobile labour, and capital. Capital mobility is linked to labour mobility since individuals move with their inheritance. The model shows that countries are homothetic in the post-migration equilibrium with equal factor prices and equal densities of population. Migration flows are bilateral and the number of each type of migrants is uniquely determined. In some cases, migration leads to a Pareto improvement in both countries.

Decades of puberty research have yielded key scientific discoveries. Building on the field's rich history, we highlight four understudied populations: youth of color, boys, sexual minority youth, and gender minority youth. We explore why scientific study has been slow to evolve in these groups and propose paths forward for exciting new work. For ethnically racially diverse youth, we discuss the need to incorporate culture and context. For boys, we highlight methodological issues and challenges of mapping existing conceptual models onto boys. For sexual and gender minority youth, we discuss unique challenges during puberty and suggest ways to better capture their experiences. With an eye toward a new era, we make recommendations for next steps and underscore the importance of transdisciplinary research.  相似文献

The purpose of this study was to examine the associations among racial discrimination, generational status, and perceptions of the economic value of education among Latina/o youth. Participants were 400 urban, low‐income, Latina/o students from a large Midwestern U.S. city who completed surveys in both 9th and 10th grades. Results revealed that more perceived racial discrimination was associated with more perceived economic limitations of education. When analyzed by generational status, more racial discrimination in 9th grade was significantly related to lower perceived economic value of education in 10th grade for third‐generation and later participants, but not for first‐ or second‐generation participants. The results provide evidence for the diverse experiences of racial discrimination and perceived economic value of education across generational groups.  相似文献

This article draws on data from an exploratory study involving an organized group of Mexican immigrant mothers engaged in community-based policy advocacy in the Pacific Northwest. Participants in the project lobbied state legislators on bills expanding the rights of undocumented immigrants—most notably, bills granting access to in-state tuition and driver’s licenses. In-depth interviews (n=12) reveal that through this process, participants came to see themselves as political subjects, despite their unauthorized legal status. Findings reveal that participants’ engagement in the policy process is centered on the idea of expressing needs and reflects their interest in improving individual, family, and community well-being. In this sense, their participation in politics flows from their roles as mothers and caregivers. By illuminating the experiences of a group—undocumented immigrant women—often overlooked in research on immigration policy and practice, this case offers a counter-narrative to the dominant portrayal of immigrant women and suggests ways to integrate community organizing and collective action into policy practice.  相似文献

The aim of this article is to develop a framework within which the role and social construction of knowledge in International Relations can be understood and theoretically underpinned. In order to do so, the article discusses post-structuralist and neo-Gramscian answers to the structure–agency debate and argues that the role of knowledge remains rather implicit in both understandings on how structure and agency are mutually constituted. The main argument of the article is that the social construction of knowledge can only be understood, if International Relations are analysed in terms of a dialectically constituted relationship between structure and agency visible in and through processes whereby science and expert knowledge are referred to as true and policy relevant. On this basis, the article develops the concept of “epistemic selectivities”, which describes how the use of science and expert knowledge to underpin strategic action leads to hegemonic patterns in the way in which (scientific) expert knowledge is related to particular claims of policies and facts.  相似文献

Global human mobility constitutes a key mechanism for knowledge transfer. This study examines the micro-dynamics of knowledge transfer in the developed-developing country migratory context. It highlights the agentic role of return migrants in transforming overseas learning into relevant knowledge in their home contexts. Drawing on situated and relational theories of knowledge and learning, the study views knowledge transfer as a relevance discovery process. It looks at a group of highly skilled migrants who had returned from developed countries to Ethiopia. Despite their high skill, the focus of knowledge transfer was mostly in non-technical fields that include a broad range of organizational knowledge and work practices. These were made relevant to the local context through the returnees’ ‘work of reconciliation’, involving ‘engagement’, ‘alignment’ and ‘imagination’. The study challenges the standard assumption of a one-way linear flow of knowledge from developed to developing countries. It sheds new light on the migration-development link by highlighting the ‘aspirational’ aspect of migrant transnational learning.  相似文献

In a recent paper in Decision Sciences, Barton proposes the MTPD method for finding a unique solution for the nucleolus. We argue that the basis for the MTPD method is flawed because the nucleolus is always unique. Furthermore, the MTPD method is inconsistent and does not exhibit the properties desirable in a cost allocation method.  相似文献
