The economic benefits to immigrants of taking jobs in ethnic workplaces, relative to the open economy, are heavily debated. We examine longitudinally differences across immigrant categories in how the choice of ethnic or non‐ethnic workplace influences the ethnic composition of social networks and how these factors impact immigrants’ economic success. Using the Longitudinal Survey of Immigrants to Canada, with data 6 months, 2 years, and 4 years after arrival, we find support for both sides of the ethnic economy debate when it is qualified by immigrant category. While economic immigrants benefit from non‐ethnic workplaces, family immigrants face economic penalties in the open economy and do better in ethnic workplaces. We argue that policies sorting immigrants into visa categories do much of the work of leading them into segmented paths of incorporation. 相似文献

The purpose of this study was to examine the role of career barriers in social cognitive career theory (R. W. Lent, S. D. Brown, & G. Hackett, 1994). The participants were 584 high school students in Taiwan, Republic of China. The gender differences in perceived career barriers and career self‐efficacy were significant. Results of hierarchical regression analyses indicated that some of the perceived career barriers were significant in predicting individuals' career choice behavior after controlling for career self‐efficacy in certain career types. 相似文献

Learning to walk is a dynamic process requiring the fine coordination, assembly, and balancing of many body segments at once. For the young walker, coordinating all these behavioral levels may be quite daunting. In this study, we examine the whole‐body strategies to which infants resort to produce their first independent steps and progress over the first months of walking experience. Six infants were followed weekly from the onset of independent upright locomotion for 8 weeks, and then every other week until 4 months of walking experience. The walking kinematics from the infants' earliest steps were cluster‐analyzed and the infants were classified into 3 groups. Follow‐up comparisons with kinematics recordings were used to quantify the infants' strategies more precisely and track how these early forms of walking evolved over time. Results revealed that in the first weeks of independent walking, 3 infants used a stepping strategy, 1 used a twisting strategy, and 2 used a falling strategy to move their body forward and perform their first unsupported steps. As the infants gained walking experience, their walking patterns became more similar. These findings indicate that infants discover different solutions to use their body and control their balance when beginning to walk. With time, infants adopt a more efficient solution that incorporates and integrates elements of the different strategies. 相似文献

A model for the assessment of exposure to Listeria monocytogenes from cold-smoked salmon consumption in France was presented in the first of this pair of articles (Pouillot et al ., 2007, Risk Analysis, 27:683–700). In the present study, the exposure model output was combined with an internationally accepted hazard characterization model, adapted to the French situation, to assess the risk of invasive listeriosis from cold-smoked salmon consumption in France in a second-order Monte Carlo simulation framework. The annual number of cases of invasive listeriosis due to cold-smoked salmon consumption in France is estimated to be 307, with a very large credible interval ([10; 12,453]), reflecting data uncertainty. This uncertainty is mainly associated with the dose-response model. Despite the significant uncertainty associated with the predictions, this model provides a scientific base for risk managers and food business operators to manage the risk linked to cold-smoked salmon contaminated with L. monocytogenes. Under the modeling assumptions, risk would be efficiently reduced through a decrease in the prevalence of L. monocytogenes or better control of the last steps of the cold chain (shorter and/or colder storage during the consumer step), whereas reduction of the initial contamination levels of the contaminated products and improvement in the first steps of the cold chain do not seem to be promising strategies. An attempt to apply the recent risk-based concept of FSO (food safety objective) on this example underlines the ambiguity in practical implementation of the risk management metrics and the need for further elaboration on these concepts. 相似文献

Recent studies on transnational mothering have explored the various strategies migrant women use to negotiate their absence from home; however, there is limited knowledge on how migration status diversifies transnational mothering practices. To fill this gap, I conducted in‐depth interviews and observations of Filipino migrant mothers working in the domestic service sector in and around Paris. The consequences of migration include the prolongation of a planned stay in France, emotional difficulties due to family separation, and distant mother–child relationships. Transnational family life appears more complicated and difficult to manage for undocumented migrant mothers since they cannot easily visit their family back home, which they try to compensate by resorting to more intense transnational communication and gift‐giving practices. Hence, migration status plays an important role in shaping transnational motherhood. 相似文献

In an attempt to determine if a community standard existed and to relate judgments of pornography to conservatism, scores on Wilson and Patterson's Conservatism Scale, yes‐no judgments on whether 25 pictures were or were not pornographic, and demographic data were obtained from a random sample (N = 114) of a community. Results were as follows: (1) suggestive evidence for the existence of a community standard; (2) the c‐scale correlated .57 (N = 114, p < .01) with number of pictures judged pornographic; (3) the 25 pictures met Guttman requirements of unidimensionality (reproducibility of .925); and (4) factor analysis of the pornography judgments yielded three clear‐cut factors and one ambiguous factor which were ordered along the Guttman dimension. 相似文献

This paper analyzes the “gender strategies” of a sample of Israeli women social workers as evidenced in the recommendations that they write for the courts on custody and visiting rights for divorcing couples. Textual analysis of these reports reveals what Hochchild terms a “traditional gender strategy,” manifested in a consistent pattern of gender stereotyping. There are clear differences in the way the social workers present the husband and wife as persons, both separately and in relation to one another, and in the roles that they expect them to fulfill, with the man being assigned the provider role and the woman the parent role. Even the way they collect information about the two parents' relationships with their children is different. The paper concludes with a discussion of the practical implications of the findings. 相似文献
