Foreign Student Emigration to the United States: Pathways of Entry,Demographic Antecedents,and Origin‐Country Contexts 下载免费PDF全文
This study uses data from various sources to examine the determinants of trends in international student migration to the United States. Our results highlight the differential contributions to these trends made by various entry pathways. For example, we find that the overall growth was driven by students using visas that offered the least possibility of US employment following the completion of their studies. We also find that overall student migration trends were significantly affected by global demographic changes. For example, student emigration from Europe was negatively affected by declining fertility trends, percentage of youths, and youth population size. In Asia and Africa, contrasting demographic trends explained the substantial student migration increases observed from these regions. Increases in youth population size had a particularly positive effect on student migration in contexts of economic growth. Finally, the analysis finds a declining significance of English language contexts for fueling overall student migration trends. 相似文献

ABSTRACTThis article investigates how Swedish gay men pursue and understand fatherhood, using a qualitative, semi-structured methodological approach. We are interested in how practical issues and different fatherhood arrangements are understood and handled by the fathers; how the construction of “rainbow families” is understood in relation to legal issues; parental responsibilities; and thoughts regarding gender-equal and gender-neutral relationships within Swedish society and culture. The results show that the trajectory of gay men toward fatherhood is shaped by a variety of mediating factors such as interactions with agencies, clinics, attorneys, and the state. There are some significant legal, social, financial, and cultural obstacles to realizing gay parenthood. There are also cases where study participants talked about a sense of intolerance expressed toward gay parents within a gay community. Although there are still strong normative dimensions involved in the construction of modern parenthood, the grip of heteronormative views on family life and sexuality is changing; the narratives presented also represent a questioning of the hegemonic image of fatherhood in Sweden. Consequently, it is possible to discern different attempts at transgressing and changing the cultural landscape of fatherhood and the ways people build families today. 相似文献

It has long been asserted that in univariate location-scale models, when concerned with inference for either the location or scale parameter, the use of the inverse of the scale parameter as a Bayesian prior yields posterior credible sets that have exactly the correct frequentist confidence set interpretation. This claim dates to at least Peers, and has subsequently been noted by various authors, with varying degrees of justification. We present a simple, direct demonstration of the exact matching property of the posterior credible sets derived under use of this prior in the univariate location-scale model. This is done by establishing an equivalence between the conditional frequentist and posterior densities of the pivotal quantities on which conditional frequentist inferences are based. 相似文献

In this paper, we establish the role of concomitants of order statistics in the unique identification of the parent bivariate distribution. From the results developed, we have illustrated by examples the process of determination of the parent bivariate distribution using a marginal pdf and the pdf of either of the concomitant of largest or smallest order statistic on the other variable. An application of the results derived in modeling of a bivariate distribution for data sets drawn from a population as well is discussed. 相似文献

Mixture distributions have become a very flexible and common class of distributions, used in many different applications, but hardly any literature can be found on tests for assessing their goodness of fit. We propose two types of smooth tests of goodness of fit for mixture distributions. The first test is a genuine smooth test, and the second test makes explicit use of the mixture structure. In a simulation study the tests are compared to some traditional goodness of fit tests that, however, are not customised for mixture distributions. The first smooth test has overall good power and generally outperforms the other tests. The second smooth test is particularly suitable for assessing the fit of each component distribution separately. The tests are applicable to both continuous and discrete distributions and they are illustrated on three medical data sets. 相似文献

What we know about the experiences of black teachers is limited, especially considering the vast amount of research conducted on and about black boys and young men. This article describes and analyzes how a black teacher at a suburban high school in the Midwestern United States negotiated professional relationships through culturally relevant discourse. Anthony Bell was the only black male teacher participating in a classroom discourse analysis study group at a diverse suburban high school. Throughout the course of the semester, Anthony’s stated objective for learning discourse analysis was to understand, structure, and facilitate more productive conversations with a struggling student teacher he was mentoring. Yet Anthony also used his discursive inquiry to “trouble the water” in his classroom and in the study group workshops. Participation in the study group provided Anthony with metalinguistic tools to critique his interactions with his students, student teacher, and professional peers. Anthony’s analyses of his own teaching, his student teacher’s work, the study group, and the school index themes in critical and critical race theory in education. As he became a teacher researcher, Anthony reported a greater sense of professional self-efficacy, eventually facilitating a successful workshop at a national teacher conference. Anthony’s case is an exemplar of the unique and critical role of black men who teach, as well as the imperative of practitioner research within the current climate in teacher education. 相似文献

Many immigrants in Western countries hail from countries where attitudes towards gender relations and sexual norms are considerably more conservative than in the host countries where they eventually settle. This paper assesses whether immigrants and their children acculturate in this dimension, and how migrants’ cultural practices and economic integration influence this process. Presenting a conceptual and methodological innovation, this paper treats acculturation as a process by which immigrants (and their children) shift from the attitude distribution in the origin country to the one of the host country. Using a cross-classified hierarchical regression model and data on attitudes towards homosexuality in 83 countries of origin and 23 destination countries, I model the relative influence of origin and destination contexts on the attitudes of 15,000 immigrants and children of immigrants in Europe. In line with previous work, I find considerable evidence for acculturation across and within generations, but also important variation: respondents who use the home-country language, who are religious, or who are economically marginalised, show less acculturation in attitudes, though these effects vary between immigrants and the second generation. 相似文献
