This study aimed to test the “healthy immigrant” hypothesis and assess health heterogeneity among newly arrived working-age
immigrants (18–64 years) from various regions of origin. Using the 5% sample of the 2000 U.S. Census (PUMS), we found that,
compared with their native-born counterparts, immigrants from all regions of the world were less likely to report mental disability
and physical disability. Immigrants from selected regions of origin were, however, more likely to report work disability.
Significant heterogeneity in disabilities exists among immigrants: Those from Eastern Europe and Southeast Asia reported the
highest risk of mental and physical disability, and those from East Asia reported the lowest risk of physical disability.
Furthermore, Mexican immigrants reported the lowest risk of mental disability, and Canadian immigrants reported the lowest
risk of work disability. Socioeconomic status and English proficiency partially explained these differences. The health advantage
of immigrants decreased with longer U.S. residence. 相似文献

Commonly used tests to detect carcinogenic potential of a test compound make extreme assumptions about the lethality of tumors, due to their occult nature. In this paper we compare a nonparametric test, which uses interim sacrifice to avoid such assumptions, with these tests using simulation based on the EDOl data. Results indicate that in the presence of a significant difference in the mortality rate with treatment, commonly used methods could fail to maintain the nominal significance level. However, when there is no difference in the mortality rate, such procedures are robust to the underlying assumptions about the lethality of tumors and more powerful than the nonparametric test using interim sacrifice. 相似文献

We formulate a modified version of the Hoerl-Kennard ridge regression method to solve the problem of estimating coefficients in economic relationships. We investigate two approaches for determining the biasing parameter One approach utilizes prior information in choosing jr, the other approach estimates y from the sample data. Monte Carlo experiments are used to evaluate the relative efficiencies of alternative ridge estimators. 相似文献

We investigated associations of sexual desire with time of day, physical and social context, and positive and negative affect using momentary sampling in 44 depressed young women (mean age = 18). Analyses revealed that depressed young women experienced sexual desire when with their boyfriends and later in the evening. Sexual desire was also positively associated with positive affect. Sexual desire was not associated with negative affect or physical context. This research suggests that sexual desire is experienced by depressed young women in normative developmental social contexts. Our findings may help clinicians and sexual health educators in correcting the myth that depressed women do not have sexual desire. 相似文献

The study was conducted on 20 farm workers to identify the occupational health hazards in threshing operation. Four different protective masks were given and tested on various parameters. Respondents reported respiratory health problems which were mainly due to heat and organic dust in the surroundings. All respondents reported irritation in eyes and throat followed by nose (85.0%) and ears (75.0%). Musculo-skeletal problems were reported showing severe to very severe discomfort in lower arms (m.s. = 3.8), upper back (3.6) and upper arms (3.4). Overall discomfort score (ODS) was 7.6 depicting high level of discomfort. Peak expiratory flow rate was reduced by 6.6 % depicting reduced capacity of lungs after day long work in polluted environment. Hood mask was highly acceptable as it showed lowest breathing resistance. Leakage of dust from sides and rate of sweating was medium. Hence, use of hood mask would be helpful to achieve the ergonomics objective of reducing health problems and improving performance. 相似文献

This article provides a brief and concise account of Hollywood’s long engagement with cinema and the audience in India. The focus is on the new phase that this complex relationship has entered, with Hindi films being produced under the direct and total control of Hollywood-based producers and financiers, on an experimental basis. 相似文献

Let be k independent populations having the same known quantile of order p (0 p 1) and let F(x)=F(x/i) be the absolutely continuous cumulative distribution function of the ith population indexed by the scale parameter 1, i = 1,…, k. We propose subset selection procedures based on two-sample U-statistics for selecting a subset of k populations containing the one associated with the smallest scale parameter. These procedures are compared with the subset selection procedures based on two-sample linear rank statistics given by Gill & Mehta (1989) in the sense of Pitman asymptotic relative efficiency, with interesting results. 相似文献

The paper makes an attempt to examine financing of urban services within the broader macro-economic liberalisation and decentralisation context in India. It estimates the resource gap between the present flow of funds and financial requirements for urban civic services on the basis of the existing un-met demand and projected population growth trends. While making a case for appropriate pricing and cost recovery for generating more resources for financing urban services, the paper focuses on the changing attitude towards full-cost recovery, existing practices of pricing and cost recovery of urban services, provides empirical evidence of poor cost recovery from four Indian cities and identifies key institutional, conceptual and managerial issues that need to be addressed. Finally, the paper presents the emerging directions for policy reforms and action for meeting the growing needs for urban infrastructure and services, which includes some measures for fiscal reforms to increase the flow of finances for urban infrastructure and services, strengthening the resource base of local agencies and capacity building of local agencies. 相似文献
