This article examines the initial labor market outcome and the subsequent mobility process of Chinese immigrants in Colonial Hong Kong using complete work history data and event history modeling. Contrary to the rhetoric that Hong Kong is a capitalist paradise for adventurers, the data showed that immigrants were penalized in their initial class placement, subsequent mobility, and current income attainment. Differences in educational attainment and the lack of transferability of pre‐migration human capital partly explained the attainment gap between immigrants and the natives. Yet the disadvantage of immigrants was also embedded in the local economic structure. The process of deindustrialization significantly lowered the chance of immigrants getting good first jobs when entering the labor market. Moreover, since deindustrialization benefited the natives by providing them with more opportunities in the service sector, it inadvertently widened the gap in upward mobility chances between natives and immigrants. 相似文献

Action‐oriented research is a methodological approach for doing collaborative research with practitioners and community partners that can inform practice, programs, community development, and policy while contributing to the scientific knowledge base. This article discusses how family scholars can use action‐oriented research to work together with community partners to address their need for useful information about their practices and programs. We present some practical strategies that can help guide the action‐oriented research process including how to develop collaborative relationships with community partners; suggestions for determining sound, action‐oriented research questions; guidelines for selecting and implementing appropriate research designs; and considerations regarding data collection and the dissemination of findings. 相似文献

In scheduling medical residents, the objective is often to maximize resident satisfaction across the space of feasible schedules, relative to the many hard constraints that ensure appropriate patient coverage, adequate training opportunities, etc. A common metric of resident satisfaction is the number of time‐off requests that are granted. Simply maximizing this total, however, may lead to undesirable schedules since some requests have higher priority than others. For example, it might be better to grant one resident's request for a family member's wedding in place of two residents’ requests to attend a rugby game. Another approach is to assign a weight to each request and maximize the total weight of granted requests, but determining weights that accurately represent residents’ and schedulers’ preferences can be quite challenging. Instead, we propose to identify the exhaustive collection of maximally feasible and minimally infeasible sets of requests which can then be used by schedulers to select their preferred solution. Specifically, we have developed two algorithms, which we call Sequential Request Selection Via Cuts (Sequential RSVC) and Simultaneous Request Selection Via Cuts (Simultaneous RSVC), to identify these sets by solving two sequences of optimization problems. We present these algorithms along with computational results based on a real‐world problem of scheduling residents at the University of Michigan C.S. Mott Pediatric Emergency Department. Although we focus our exposition on the problem of resident scheduling, our approach is applicable to a broad class of problems with soft constraints. 相似文献

Government policy on services for the elderly is to increase the provision of care in the community. This paper examines this policy in relation to informal help received from relatives and friends.
Drawing on the results of a pilot study of 92 people over the age of 75, registered in a group general practice, data are presented on the balance between informal and formal help over a group of activities of daily livhg. The main informal helpers are described with the range of activities for which people in the study were receiving assistance.
Community services are, at present, limited in the help they can provide for people in their own homes. If policies of community care are to be successful, then they must take into account the strengths and weaknesses of informal support. Using the data presented, suggestions are made a bout improvements in services including task specific services not currently provided and the definition of groups at risk of their social support breaking down. 相似文献

Business portfolio analysis is becoming an increasingly important and indeed critical element in strategy analysis, and the problem of cross subsidization will almost certainly become an issue of some importance for managements under the influence of the new Price Commission. This article analyzes the problem of developing corporate strategy on the basis of the individual contributions which inter-dependent groups of services and products make to the company's profitability, stability and future potential. 相似文献

In studying correlates of social behavior, attitudes, and beliefs, a measurement model is required to combine information across a large number of item responses. Multiple constructs are often of interest, and covariates are often multilevel (e.g., measured at the person and neighborhood level). Some item–level missing data can be expected. This paper proposes a multivariate, multilevel Rasch model with random effects for these purposes and illustrates its application to self–reports of criminal behavior. Under assumptions of conditional independence and additivity, the approach enables the investigator to calibrate the items and persons on an interval scale, assess reliability at the person and neighborhood levels, study the correlations among crime types at each level, assess the proportion of variation in each crime type that lies at each level, incorporate covariates at each level, and accommodate data missing at random. Using data on 20 item responses from 2842 adolescents ages 9 to 18 nested within 196 census tracts in Chicago, we illustrate how to test key assumptions, how to adjust the model in light of diagnostic analyses, and how to interpret parameter estimates. 相似文献

Household demographic factors as life cycle determinants of land use in the Amazon 总被引:10,自引:0,他引:10
This paper seeks to broaden the application of demographyto environmental studies by complementing existing macro-level approaches, which feature aggregate populations, with a micro-level approach that highlights household life cycles. I take up the case of small farm households in the Brazilian Amazon to present a theoretical framework that identifies demographic characteristics which dispose families to engage in different forms of land use as household age structures change. Empirical models show that net of theeffects of farmer background, neighborhood context, institutional context, and off-farm incomes, demographic variables indicative of the household life cycle exert significant effects on the prominence of land uses with distinct environmental ramifications. The findings not only reveal micro-level demographic factors which affect Amazon land cover, they yield implications forfuture changes in rainforest landscapes in northern Brazil, and suggest household life cycle models as an avenue for further demographic research on environmental change in Latin America and other contexts. 相似文献

This study focuses on four aspects of theinequality of average household income amongthe American states. First, we document changein the inequality of nominal average householdincome between 1979 and 1990. Second, weidentify states contributing to the observedinequality. Third, we examine the pattern instate income convergence-divergence whenspatial and temporal state price differentialsare accounted for. Fourth, we provide estimatesof impacts of alternative income components onincome inequality. We find that inequality inreal income is smaller than that in nominalincome. Also, we conclude that traditionalincome measures that exclude transfer paymentsand other types of income overstateinequality. 相似文献

Current government policy places great importance both on clinical governance and on partnership working between health and social services. Separately and together, these policy emphases require greater clarity in and between organizations about who should provide what care where than has often been achieved in the past. A study of the implementation of continuing health care policies suggests that clarity about appropriate long–term health and social care provision was difficult to achieve in the 1990s quasi–markets, because there were too few financial and structural incentives for agencies to cooperate in developing and implementing precise and comprehensive eligibility criteria. This problematic interplay between financial and structural factors is being addressed by a number of government initiatives designed to stimulate joint working, although the difficulty of drawing a clear boundary between health care (free at the point of delivery) and social care (which can be means–tested) remains. 相似文献

The English language fluency and occupational success of ethnic minority immigrant men living in English metropolitan areas 总被引:1,自引:1,他引:0
This paper examines two crucial aspects of the assimilation experience of ethnic minority immigrants in the United Kingdom.
It explores the determinants of their English language (speaking) fluency and the key role such skills play in their occupational
success. Our sample is derived from the Fourth National Survey of Ethnic Minorities undertaken in 1994. Uniquely this data
contains an interviewer-assessed measure of English language fluency. Importantly, we also attempt to control for possible
endogeneity bias in the estimates of the effect of language fluency on occupational success. We find that fluency is associated
with significantly higher mean hourly occupational wages.
