In the 1990s, Colombia, the Dominican Republic, Ecuador, Costa Rica, and Brazil passed dual citizenship laws granting their expatriates the right to naturalize in the receiving country without losing their nationality of origin. I estimate the effects of these new laws on naturalization rates and labor market outcomes in the United States. Based on data from the 1990 and 2000 U.S. censuses, In find that immigrants recently granted dual nationality rights are more likely to naturalize relative to immigrants from other Latin American countries. They also experience relative employment and earnings gains, together with drops in welfare use, suggesting that dual citizenship rights not only increase the propensity to naturalize but may also promote economic assimilation. The effects of dual citizenship on improved economic performance, if mediated through naturalization, are consistent with American citizenship conferring greater economic opportunities.  相似文献

ABSTRACT.Objectives: We conducted a survey to obtain information concerning how mothers of children with DSD represent the diagnosis. Methods: We examined our findings through IPA methodology. Results: We observed a crisis of meaning, based on the inability to classify their child with a milestone of the social experience: the gender category. That risks of slipping into adempitive adherences to medical knowledge or hasty decisions about the health of the child. Conclusions: It's necessary to structure spaces with medical-psychological teams, for allowing these families to manage the condition in relation to the choices, and the daily context, of their children.  相似文献

To better understand the form and recognizability of neonatal smiling, 32 newborns (14 girls; M = 25.6 hr) were videorecorded in the behavioral states of alertness, drowsiness, active sleep, and quiet sleep. Baby Facial Action Coding System coding of both lip corner raising (simple or non‐Duchenne) and lip corner raising with cheek raising (Duchenne smile) was followed by a smile recognition task using 48 naive observers. Both types of smiles were detected in all behavioral states. Lip corner raising with cheek raising (Duchenne smiling) tended to predominate in active (rapid eye movement) sleep, suggesting a potential tie to early constituents of emotion. A significant portion of the typically briefer lip corner raising distinguished by expert coders was not recognized as smiling by the naive observers. These briefer actions may represent a motor phenomenon idiosyncratic to the neonatal period.  相似文献

The article compares participatory research and alternative activist approaches, based on the literature on participatory research and interviews with nine successful sociologists who use alternative approaches. Participatory research, distinguished by high control over research by community members, equalizes power within the research process, but often retards academic publication and career advancement. The interviews show that successful academics retain control over their research, experience mild to severe conflicts with departments, and develop various strategies for combining activism and career success. All types of activist research are more effective in challenging inequality if they involve activist community organizations. Her research has focused on family, gender, and feminist and participatory methods. Recent publications includeLove in America, “Feminist Science,” and “Participatory Research” with Cathleen Armstead. Her current participatory research project explores “Family and Community Caring” in a Mexican-American community. Address for correspondence: Francesca M.

We study the effects of immigration on the diversity of consumption choices. Data from California in the 1990s indicate that immigration is associated with fewer stand-alone retail stores and a greater number of large and in particular big-box retailers—evidence that likely contradicts a diversity-enhancing effect of immigration. In contrast, focusing on the restaurant sector for which we can better identify the types of products consumed by customers, we find that immigration is associated with increased ethnic diversity of restaurants. This latter effect appears to come in part from the comparative advantage of immigrants in the production of ethnic goods.  相似文献

In the last decades it has been necessary to face emergencies due to big crisis events caused by anthropic and natural events. In particular modern technological systems have reached such a high level of complexity that even a simple event can influence correct behavior with potential catastrophic consequences. The security and economy of technologically developed countries depends on the correct behavior of this infrastructure and on the continuity of the services that they grant. In this framework, risk management assumes an important role focusing on policies for vulnerability reduction and after-crisis management. It imposes a multidisciplinary and transnational approach in order to establish a common strategy between different countries, studying how to be prepared for disasters and prevent disaster damage. In this paper a preliminary analysis of risk categories is presented, suggesting a number of tentative proposals for risk reduction.  相似文献

Since the end of apartheid, South Africa has been characterized by a dualistic economic structure. It is a developed country compared to the African context, but it is still developing for many problems such as high unemployment rates, low levels of foreign direct investments and saving, inflation, and the general levels of poverty and inequality. In this sense, the recent national election, held on 22 April 2009, has a crucial role. The high percentage of voters shows that there is a common sense of revenge. People want to believe that a new beginning is possible. The ANC victory and the election of Jacob Zuma as president appear to be the first steps in order to realize this change. Nevertheless, this national support clashes with international concerns. The background of J. Zuma, the increasingly close cooperation between South Africa and China, as well as the proximity and politic instability of Zimbabwe make international observers skeptical about Zuma’s actions. In the light of the economic and social problems of South Africa, the aim of this paper is to analyze these aspects in order to imagine what the future holds for South Africa.  相似文献
