Asian immigrants accounted for one-eighth of the total U.S. population in 2009. With Asian immigrants having higher levels
of education and income than average Americans, their potential contribution to American philanthropy will be even more significant.
This study examines the volunteering patterns of Korean immigrants, one of the fastest growing segments of the Asian immigrant
population in the United States. This study explains Korean immigrants’ volunteering within ethnic and mainstream (American)
organizations using the concepts of bonding and bridging social capital. The bivariate probit regression results suggest that
ethnic volunteering and mainstream volunteering are generally the substitutes for each other. The findings nevertheless suggest
that providing Asian immigrants’ with English education and continuing education opportunities may boost their volunteering
to mainstream nonprofit organizations without discouraging their volunteering for ethnic organizations. 相似文献

A recent opinion piece published in the Sydney Morning Herald expresses a widely held perception that, among young same-sex attracted men in Australia, "queer" has well and truly supplanted "gay" as the language and lens through which self and practice is generated. In this article, I discuss findings from a qualitative research project that studied notions of community among young gay men, and argue that this assumption should not be taken for granted. The article explores participants' understandings of the concept of "gay community," arguing that the young men studied share a common definition of community: one based on a conventional liberal model which prioritizes sameness and the cooperation of individuals to achieve common goals. This is of particular importance in that problems around "fitting in" with these understandings are also raised. In examining the potential place for queer alternatives to these formulations, however, the article finds that queer attracts little support among participants, raising questions about the bind young men may find themselves in if they prioritize sameness as fundamental to community, yet feel themselves to be excluded from community by their own or others' perceived difference. 相似文献

AbstractThis investigation into the cultural dynamics of gendered, aging bodies attends to a mediated representation of what contemporary biomedicine defines as pregnancy in “advanced maternal age” (AMA). We offer a feminist rhetorical analysis of an episode of TLC’s 19 Kids and Counting entitled “A Duggar Loss,” where 45-year-old matriarch Michelle Duggar experiences pregnancy loss. In the episode, age is reconfigured in discussions of AMA pregnancy through a metonymic substitution and slippage of risk discourses, pre-natal self-care, and technological interaction. Moreover, “A Duggar Loss” mobilizes strategies of expansive affiliation around and through reproductive choice, which appears to align with feminist principles of reproductive autonomy despite the family’s ties to the Quiverfull Movement. This work contributes to feminist studies of aging bodies by suggesting that representations of advanced maternal age pregnancy remain a central, yet undertheorized subject in formulating powerful trans-ideological affiliations that can undermine progressive reproductive politics. 相似文献

While the benefit of live supervision on clinical training is largely unquestioned, research that examines how live supervision affects the therapeutic process is lacking. Although marriage and family therapy has embraced this method of supervision, there is little empirical evidence suggesting it "works." This study uses hierarchical linear modeling to examine how therapy cases utilizing live supervision affect perceptions of progress on the problem. Findings indicated that live supervision does appear to make a difference for therapists' ratings of progress on the problem over the course of therapy; however, clients did not rate their progress as improving to the same degree. Implications for the use of live supervision as well as limitations of the study are discussed. 相似文献

Initial pilot interviews with women whose husbands were in the first year of retirement revealed that problems of "impingement"--perceptions of husbands as intruders into their worlds-as-lived--were cited, in response to open-ended items, as the most difficult aspect of husbands' retirement. An impingement index, consisting of items constructed from those responses, was administered to the original panel of 83 women whose husbands were now in the fourth year of retirement, and to a new panel of 61 women whose husbands had been retired for one year. Paired T-tests revealed one significant difference in perceptions of impingement between the two groups of wives, and not in the expected direction. Indeed, wives in year 4 were more often bothered by some impingement conditions than wives in year 1, and these were significantly related to self-assessments of marital satisfaction. Results have implications for "adjustment" to life transitions, including situations that may inhibit initiation of adaptive responses, degree of investment in social roles, and issues of expectation. 相似文献

This paper studies the efficient estimation of seemingly unrelated linear models with integrated regressors and stationary errors. We consider two cases. The first one has no common regressor among the equations. In this case, we show that by adding leads and lags of the first differences of the regressors and estimating this augmented dynamic regression model by generalized least squares using the long-run covariance matrix, we obtain an efficient estimator of the cointegrating vector that has a limiting mixed normal distribution. In the second case we consider, there is a common regressor to all equations, and we discuss efficient minimum distance estimation in this context. Simulation results suggests that our new estimator compares favorably with others already proposed in the literature. We apply these new estimators to the testing of the proportionality and symmetry conditions implied by purchasing power parity (PPP) among the G-7 countries. The tests based on the efficient estimates easily reject the joint hypotheses of proportionality and symmetry for all countries with either the United States or Germany as numeraire. Based on individual tests, our results suggest that Canada and Germany are the most likely countries for which the proportionality condition holds, and that Italy and Japan for the symmetry condition relative to the United States. 相似文献

Since the National Food Safety Initiative of 1997, risk assessment has been an important issue in food safety areas. Microbial risk assessment is a systematic process for describing and quantifying a potential to cause adverse health effects associated with exposure to microorganisms. Various dose-response models for estimating microbial risks have been investigated. We have considered four two-parameter models and four three-parameter models in order to evaluate variability among the models for microbial risk assessment using infectivity and illness data from studies with human volunteers exposed to a variety of microbial pathogens. Model variability is measured in terms of estimated ED01s and ED10s, with the view that these effective dose levels correspond to the lower and upper limits of the 1% to 10% risk range generally recommended for establishing benchmark doses in risk assessment. Parameters of the statistical models are estimated using the maximum likelihood method. In this article a weighted average of effective dose estimates from eight two- and three-parameter dose-response models, with weights determined by the Kullback information criterion, is proposed to address model uncertainties in microbial risk assessment. The proposed procedures for incorporating model uncertainties and making inferences are illustrated with human infection/illness dose-response data sets. 相似文献

Current implementations of Asimov's Grand Tour (for example in XLISP-STAT by Tierney, 1990, or in XGobi by Buja et al., 1996) do not remember the path of projections and show only the current state during the touring process. We propose a modification of the Grand Tour, named Tracking Grand Tour (TGT), that shows the trace of the touring process as small 'comet trails' of the projected points. The usefulness of the TGT is demonstrated with a simulated and a real data set. 相似文献
