This article explores the issue of gender role changes encountered by young Vietnamese-American women based on our ethnographic study of Versailles Village, a low-income ethnic community in New Orleans, US.
We examine how female Vietnamese high school students deal with conflicts between the stubborn traditionalism of parents and the desire for personal liberty of American-reared children and how they negotiate gender roles at home and in school and society.
Through in-depth examination of the school experience of young Vietnamese women, we find that they not only equal young men in scholastic performance and ambition, but may even show higher levels of achievement. Our data indicate that it is not because the women are liberating themselves from traditional gender roles in order to avail themselves of the opportunities of American society. Instead, the socio-economic conditions of the new land place a new emphasis on education for both men and women.
Immigrant families see the importance of education as an avenue of upward mobility for their children and encourage educational achievement. Precisely because traditional gender roles lead families to exercise greater control over daughters, young women are pushed even more than young men toward scholastic performance.  相似文献

This paper traces the development of the voluntary and community sector in Northern Ireland from the early 1970s onwards. Particular attention is given to the expansion of the voluntary and community sector in the 1970s, community action in conflict with government in the 1980s, and new funding--from the European Union and other international sources--for development work since the mid-1990s. More recent trends discussed include the rapprochement of the voluntary and community sector with government, which has seen a growth in formal partnerships and networking, as well as the impact of the 1998 Belfast Agreement.  相似文献

In the year prior to Hillary Clinton's and Barack Obama's bids to become the Democratic nominee for the U.S. presidency, we explored children's views about the role of race and gender in the U.S. presidency, with a specific focus on perceptions of discrimination. Specifically, we examined children's (aged 5 to 10) knowledge of and attributions for the lack of female (Study 1, N = 76), African American (Study 2, N = 64), and Latino (Study 3, N = 65) presidents. Results indicated that children are knowledgeable about the gender, race, and ethnicity of past presidents, and that many children attribute the lack of female, African American, and Latino presidents to gender and racial discrimination. Theoretical and policy implications of the work are discussed.  相似文献

Objective. We make use of individual‐level survey data from the 2006 midterm election in order to determine the degree to which redistricting affected the vote choice of whites residing in Georgia Congressional Districts 8 and 12. Methods. A multivariate probit model was used to assess the probability of voting for the GOP House candidate among voters represented by the same incumbent before and after redistricting versus voters who had been newly drawn into one of these districts. Results. Despite a national tide that favored the Democratic Party in the 2006 elections, redrawn whites were more likely to vote for the Republican challengers in the districts surveyed. Conclusions. Our findings indicate that redistricting can be used to dampen the incumbency advantage. In addition, the findings of this research also speak to the continuing Republican realignment of white voters in the Deep South and to the recognition that the effects of redistricting are dependent on political context.  相似文献

Objective. Growth in the share of high‐technology employment is critical to discussions of the postindustrial transition. Do new state and local technology policies create growth in the share of high‐technology employment? This article examines this question along with the effects of location and agglomeration advantages, identifying sources of qualitative growth in the U.S. economy. Methods. We examine change in the share of high‐technology employment in metropolitan statistical areas (MSAs) in the United States between 1988 and 1998. High‐technology employment is measured from the BLS Current Employment Statistics Survey. The scale of state and local technology policies are measured from a comprehensive survey of state and local technology programs. A generalized linear model (GLM) estimates the effects of technology policies along with regional proximity, location, and agglomeration factors. Results. Technology grant and loan programs and research parks have direct effects on the share of high‐technology employment, along with private venture capital firms and military R&D. Research parks also magnify the effects of private venture capital firms, while public venture programs and technology development policies compensate for agglomeration deficits. Rapid population growth provides a more conducive context for these policies but does not directly influence growth in the share of high‐technology jobs. Conclusion. State and local technology policies compensate for and magnify the effects of agglomeration advantages, indicating that state and local government can play a strategic role in high‐technology development.  相似文献

Consider the model where there are II independent multivariate normal treatment populations with p×1p×1 mean vectors μiμi, i=1,…,Ii=1,,I, and covariance matrix ΣΣ. Independently the (I+1)(I+1)st population corresponds to a control and it too is multivariate normal with mean vector μI+1μI+1 and covariance matrix ΣΣ. Now consider the following two multiple testing problems.  相似文献

The Wehrly–Johnson family of bivariate circular distributions is by far the most general one currently available for modelling data on the torus. It allows complete freedom in the specification of the marginal circular densities as well as the binding circular density which regulates any dependence that might exist between them. We propose a parametric bootstrap approach for testing the goodness-of-fit of Wehrly–Johnson distributions when the forms of their marginal and binding densities are assumed known. The approach admits the use of any test for toroidal uniformity, and we consider versions of it incorporating three such tests. Simulation is used to illustrate the operating characteristics of the approach when the underlying distribution is assumed to be bivariate wrapped Cauchy. An analysis of wind direction data recorded at a Texan weather station illustrates the use of the proposed goodness-of-fit testing procedure.  相似文献

Residential lawns provide chronosequences to examine influences of home age and aboveground tree biomass (ATB) on soil carbon (C) levels. Soil C dynamics were compared between 44 lawns with trees (LwT) and 23 without trees (PL). At the 0–15 cm depth, LwT had higher mean soil C than PL and an earlier rise in median soil C across home age. Nonparametric quantile regression also showed a steeper rise in the 5th, 50th, and 95th soil C quantiles for LwT. Fitted polynomial regression models indicated that home age and ATB together accounted for 40 % of the soil C variation at the 0–15 cm depth [C = 1.34 + 0.05(Age) + 0.0003(ATB)]. At the 15–30 cm depth, the interaction between home age and ATB explained 33 % of the soil C variation [C = 0.78 + 0.0003(Age*ATB)]; at 30–50 cm, ATB was responsible for 20 % [C = 0.56 + 0.0003(ATB)].  相似文献

W. Brian Arthur 《Demography》1984,21(1):109-128
Many seemingly different questions that arise in the analysis of population change can be phrased as the same technical question: How, within a given demographic model, would variable y change if the age- or time-specific function f were to change arbitrarily in shape and intensity? At present demography lacks the machinery to answer this question in analytical and general form. This paper suggests a method based on modern functional calculus for deriving closed-form expressions for the sensitivity of demographic variables to changes in input functions or schedules. It uses this “linkage method” to obtain closed-form expressions for the response of the intrinsic growth rate, birth rate, and age composition of a stable population to arbitrary marginal changes in its age patterns of fertility and mortality. It uses it also to obtain expressions for the transient response of the age composition of a nonstable population to time-varying changes in the birth sequence, and to age-specific fertility and mortality patterns that change over time. The problem of “bias” in period vital rates is also looked at.  相似文献
