A study sample of 162 six‐month‐old children was selected from a larger sample of 346 infants on the basis of parents' report of their infants' temperament and a laboratory assessment of temperament. Infants were classified as easily frustrated and less easily frustrated and compared on a number of emotion regulation, physiology, and temperament measures. Results indicated that male and female infants were equally likely to be classified as frustrated and less easily frustrated; however, male infants were less able to regulate physiologically. Easily frustrated infants used different emotion regulation strategies and were observed to be less attentive and more active than less easily frustrated infants when observed in the laboratory. These infants were also characterized by their parents as more active, less attentive, and more distressed to novelty. Infants classified as easily frustrated were more reactive physiologically and less able to regulate physiological reactivity than their less easily frustrated counterparts. It is hypothesized that this cluster of characteristics may constitute a unique temperamental type that may have implications for other types of behavioral functioning. Limitations of the study are that observations are based on a single brief assessment of the infant, modest effect sizes were found, and the study is cross‐sectional. 相似文献

This study tests a hypothesis that Mexican foreign‐born immigrants who came to the United States for economic reasons naturalize less often than Cubans who immigrate for political reasons. It uses information from the Panel Study of Income Dynamics, Latino Sample, a national sample of 7,453 respondents from the 1989 Latino National Political Survey (LNPS) and the 1990 Panel Study of Income Dynamics (PSID). Ordinal logistic regression is used to examine the hypothesis. The results indicate that while more Mexicans plan to apply or have applied for naturalization, proportionately more Cubans than Mexicans have naturalized. Cuban political immigrants who came to the United States during the first half of the 1960s naturalize more often than their Mexican counterparts. However, the effect of ethnic identity on naturalization is mediated by a number of other predictors of naturalization such as gender, race, urban residence, socioeconomic status and acculturation. 相似文献

Epidemiological data show high rates of suicide attempts among adolescent Latinas. Few studies have addressed the psychosocial, cultural and family correlates of suicide attempts among this age group of a rapidly growing population. The authors studied 31 adolescent Hispanic females who were receiving mental health services; 14 girls had attempted suicide in the previous five years and 17 had never attempted suicide. The two groups of girls did not differ significantly with respect to demographic profiles, levels of depression, family type, acculturation, or self-esteem. However, as hypothesized, the mutuality between girls and their mothers was lower among suicide attempters. Maladaptive coping skills of withdrawal and wishful thinking were more commonly used by attempters, and non-attempters used emotional regulation and problem-solving more frequently. Findings are discussed within the context of the empirical and theoretical literature and implications for practice are considered. 相似文献

A review of the US ‘program evaluation standards’ (PES), undertaken in a series of workshops and meetings of networks of evaluators in Africa, resulted in modifications to those standards. The result was presented to a plenary session of the Inaugural Conference of the African Evaluation Association in September 1999, attended by over 300 evaluators from 35 countries. The AfrEA Conference decided that a systematic effort should be made to produce a list of African evaluation guidelines, similar to the PES, and that this checklist should be reviewed by national evaluation associations and networks in Africa and field tested in several countries. Ten national and regional networks and associations suggested modifications to the text and endorsed the final version of the guidelines. 相似文献

In this article I deal with transnational Hindu and Muslim movements. I reject the common assertion that migrant communities are conservative in religious and social matters by arguing that ‘traditionalism’ requires considerable ideological creativity and that this significantly transforms previous practices and discourses. I suggest that religious movements, active among migrants, develop cosmopolitan projects that can be viewed as alternatives to the cosmopolitanism of the European Enlightenment. This raises a number of challenges concerning citizenship, integration and political loyalty for governmentality in the nation‐states in which these cosmopolitan projects are carried out. I suggest that rather than looking at religious migrants as at best conservative and at worst terrorist one should perhaps pay some attention to the creative moments in human responses to new challenges and new environments. 相似文献

In September 2001, the Danish Ministry of Foreign Affairs commissioned a study of the present and potential links between migration and development. In January 2002, the new Danish Government announced a decision to enhance the links between its aid and refugee policies as part of the overall focus on poverty reduction. The present paper provides a state–of–the–art overview of current thinking and available evidence on the migration–development nexus, including the role of aid in migrant–producing areas. It offers evidence and conclusions around the following four critical issues: Poverty and migration People in developing countries require resources and connections to engage in international migration. There is no direct link between poverty, economic development, population growth, and social and political change on the one hand, and international migration on the other. Poverty reduction is not in itself a migration–reducing strategy. Conflicts, refugees, and migration Violent conflicts produce displaced persons, migrants, and refugees. People on the move may contribute both to conflict prevention and reconciliation, and to sustained conflicts. Most refugees do not have the resources to move beyond neighbouring areas, that is, they remain internally displaced or move across borders to first countries of asylum within their region. Aid to developing countries receiving large inflows of refugees is poverty–oriented to the extent that these are poor countries, but it is uncertain what effect such aid has in terms of reducing the number of people seeking asylum in developed countries. Furthermore, such aid may attract refugees from adjacent countries experiencing war or political turmoil. Migrants as a development resource International liberalization has gone far with respect to capital, goods and services, but not to labour. International political–economic regimes provide neither space nor initiatives for negotiations on labour mobility and the flow of remittances. There is a pressing need to reinforce the image of migrants as a development resource. Remittances are double the size of aid and target the poor at least as well; migrant diasporas are engaged in transnational practices with direct effects on aid and development; developed countries recognize their dependence on immigrant labour; and policies on development aid, humanitarian relief, migration, and refugee protection are internally inconsistent and occasionally contradictory. Aid and migration Aid policies face a critical challenge to balance a focus on poverty reduction with mitigating the conditions that produce refugees, while also interacting constructively with migrant diasporas and their transnational practices. The current emphasis on aid selectivity tends to allocate development aid to the well performing countries, and humanitarian assistance to the crisis countries and trouble spots. However, development aid is more effective than humanitarian assistance in preventing violent conflicts, promoting reconciliation and democratization, and encouraging poverty–reducing development investments by migrant diasporas. The paper is a synthesis of current knowledge of migration–development dynamics, including an assessment of the intended and unintended consequences of development and humanitarian policy interventions. We examine whether recent developments in the sphere of international migration provide evidence of a “crisis”, as well as the connections between migration, globalization, and the changing nature of conflicts. We summarize current thinking on the main issues at stake and examine available evidence on the relations between migration and development. Then the consequent challenges to the aid community, including the current debates about coherence and selectivity in aid and relief are discussed and, finally, we elaborate on the four conclusions of the overview. 相似文献
