Temperament by parenting interactions may reflect that individuals with greater risk are more likely to experience negative outcomes in adverse contexts (diathesis‐stress) or that these individuals are more susceptible to contextual influences in a “for better or for worse” pattern (differential susceptibility). Although such interactions have been identified for a variety of child outcomes, prior research has not examined approach characteristics—excitement and approach toward pleasurable activities—in the first year of life. Therefore, this study investigated whether 6‐month maternal reported infant negative affect—a phenotypic marker of risk/susceptibility—interacted with 8‐month observed parenting behaviors (positive parenting, negative parenting) to predict 12‐month infant behavioral approach. Based on a sample of mothers and their infants (= 150), results indicated that negative parenting was inversely associated with subsequent approach for infants with high, but not low, levels of negative affect. Similar results did not occur regarding positive parenting. These findings better fit a diathesis‐stress model rather than a differential susceptibility model. Implications and limitations of these findings are discussed.  相似文献

In principle, migrants enjoy the protection of international law. Key human rights instruments oblige the States Parties to extend their protection to all human beings. Such important treaties as the International Covenant on Civil and Political Rights, and the International Covenant on Economic, Social and Cultural Rights have been ratified by more than 140 states, but many political, social or economic obstacles seem to stand in the way of offering those rights to migrants. In an attempt to bridge this protection gap, the more specifically targeted International Convention on the Protection of All Migrant Workers and Members of their Families was created and adopted by the United Nations in 1990. This treaty is not yet in force, but the number of States Parties is increasing towards the required 20. In the past few years the human rights machinery of the United Nations has increased its attention towards migrants' human rights, appointing in 1999 the Special Rapporteur on the Human Rights of Migrants. Governments, as the acceding parties to international human rights instruments, remain the principal actors as guardians of the human rights of all individuals residing in their territories. Receiving countries are in a key position in the protection of the migrants that they host. However, active defence of migrants' rights is politically difficult in many countries where anti‐immigrant factions are influential. Trafficking in migrants is one example of the complexity faced by states in formulating their migration policies. On the one hand, trafficking has made governments increasingly act together and combine both enforcement and protection. On the other, trafficking, with its easily acceptable human rights concerns, is often separated from the more migration‐related human smuggling. The latter is a more contentious issue, related also to unofficial interests in utilizing cheap undocumented immigrant labour.  相似文献

This study of 426 Canadian early adolescents (Mage = 12.52; 53% girls) investigated whether associations between popularity and indirect victimization (i.e., reputational victimization, exclusion) varied as a function of gender and the desire to conform to characteristics and competencies that are valued within the peer group (i.e., peer conformity goals). Regression analyses revealed popularity was uniquely and positively associated with reputational victimization, but was not significantly related to exclusion after accounting for the effects of meanness and likeability. The associations between popularity and indirect victimization were moderated by peer conformity goals and gender. The results indicated that popular girls with high peer conformity goals experienced more reputational victimization and exclusion than popular girls with low peer conformity goals. However, popular boys with high peer conformity goals experienced less exclusion than popular boys with low peer conformity goals. The findings suggest that peer conformity goals carry with them some risks for popular girls, but may serve a protective function for popular boys.  相似文献

Based on an extensive literature review, this paper reveals several gaps in organizational learning (OL) research that need filling before we can really talk about a theory of organizational learning or verify the traits and very existence of learning organizations (LO) as a phenomenon. The critique, however, is not targeted at any single model or theory of organizational learning, but at theory building, which constantly drifts away with new definitions and approaches that break up rather than construct a theory. Despite the fact that numerous consultation tools for turning organizations into learning models have been developed and applied, the concept of organizational learning itself still remains vague and there is an urgent need for a holistic model of OL. Too much emphasis is put on studying the learning of individuals instead of concentrating on the learning of organizations. Since the theory is highly dispersed and does not really build on earlier findings, rich empirical studies are needed in order to validate measures of organizational learning. Modelling of the organizational learning process and clarification of how learning of individuals is turned into learning of organizations is needed. This paper introduces one set of OL measures developed to study whether organizational learning occurred during the operational and business culture change process of a single case company. Suggestions for further OL research are made on the basis of experiences gained when empirically testing this model.  相似文献

Marriage or dissolution? Union transitions among poor cohabiting women   总被引:1,自引:0,他引:1  
Lichter DT  Qian Z  Mellott LM 《Demography》2006,43(2):223-240
The objective of this paper is to identify the incentives and barriers to marriage among cohabiting women, especially disadvantaged mothers who are targets of welfare reform. We use the newly released cohabitation data from the National Longitudinal Survey of Youth (1979-2000), which tracks the partners of cohabiting women across survey waves. Our results support several conclusions. First, cohabiting unions are short-lived--about one-half end within one year, and over 90% end by the fifth year. Unlike most previous research, our results show that most cohabiting unions end by dissolution of the relationship rather than by marriage. Second, transitions to marriage are especially unlikely among poor women; less than one-third marry within five years. Cohabitation among poor women is more likely than that among nonpoor women to be a long-term alternative or substitute for traditional marriage. Third, our multinomial analysis of transitions from cohabitation into marriage or dissolution highlights the salience of economically disadvantaged family backgrounds, cohabitation and fertility histories, women's economic resources, and partner characteristics. These results are interpreted in a policy environment that increasingly views marriage as an economic panacea for low-income women and their children.  相似文献

Using the literature on achievement differences as a framework and motivation, along with data on New York City students, we examine nativity differences in students’ rates of attendance, school mobility, school system exit, and special education participation. The results indicate that, holding demographic and school characteristics constant, foreign‐born have higher attendance rates and lower rates of participation in special education than native‐born. Among first graders, immigrants are also more likely to transfer schools and exit the school system between years than native‐born, yet the patterns are different among older students. We also identify large variation according to birth region.  相似文献

This paper explores the effect of the human capital characteristics of co‐ethnic immigrant communities on foreign‐born students’ math achievement. We use data on New York City public school foreign‐born students from 39 countries merged with census data on the characteristics of the immigrant household heads in the city from each nation of origin and estimate regressions of student achievement on co‐ethnic immigrant community characteristics, controlling for student and school attributes. We find that the income and size of the co‐ethnic immigrant community has no effect on immigrant student achievement, while the percent of college graduates may have a small positive effect. In addition, children in highly English proficient immigrant communities test slightly lower than children from less proficient communities. The results suggest that there may be some protective factors associated with immigrant community members’ education levels and use of native languages.  相似文献
