"The prospects for today's second generation will be considerably shaped by their current social, economic and demographic status. This article provides a statistical portrait of children of immigrants by analyzing data from the 1990 U.S. Census of Population and Housing. With the second generation defined as children under age 18 with at least one foreign-born parent, the study describes place of residence; household demographic, social and economic circumstances; household head's socioeconomic status; and characteristics of children themselves. Data on second-generation children are broken down by year of immigration of parents and child's nativity. Data for children with native-born parents are provided for comparison."  相似文献

This article describes the establishment in 1990 of a School of Medicine at Ahfad University for Women in Sudan. The school was premised on the view that women doctors would have a better opportunity to affect and improve women's health than men doctors. The curriculum is innovative and relies on a community orientation and a problem-solving approach. Medicine and health are taught in a holistic way. The new approach is rooted in the Alma Ata Declaration in 1978 of Health for All by the year 2000. The new method of delivery of medical care in the School of Medicine is based on the promotion of health through health education, prevention of disease, proper nutrition, provision of a safe water supply, attention to maternal/child health and family planning, and attention to the treatment of endemic diseases. In order to teach primary health care, medical schools must change their practices. Delivery of health care will have to be changed. New curriculum approaches emphasize learning objectives in each of the teaching modules and small group teaching. Integrated learning means the separate disciplines of medicine are taught as a whole multidisciplinary unit. Case management learning has the potential for increasing motivation and the ability to discover the knowledge needed to solve the problem. McMaster University relies on a problem-oriented approach to medical education that prepares the student for coping with changes in medical knowledge in the future. The challenge for educators is to create an efficient and comprehensive curriculum that will prepare a doctor for lifelong learning. Health settings have also changed to deemphasize sophisticated hospital settings in favor of community-based health centers. Ahfad University is the only one of its kind in Sudan. Medical education includes 6 years of schooling divided into 3 phases.  相似文献

"This paper focuses on the effects of age at marriage and the sex-ratio on patterns of ethnic homogamy among Israeli women. We hypothesize that later marriages are more likely than early marriages to be heterogamous as the 'marriage market' shifts from school to the work-place. By the same token, when facing severe marriage squeezes women will be forced to out-marry. Employing data from the 1983 census, we model mate selection of women from Afro-Asian and Euro-American origin in various birth-cohorts. The results do not fully support our hypotheses: we find that in and of itself, age at marriage does not enhance ethnic heterogamy."  相似文献

"The purpose of this paper...is twofold: first, to specify a way of calculating place utility so that potential migrants could move to the place where overall place utility is maximized; and second, which is more important, to reveal how decision-makers in the real world, who are acting within 'bounded rationalities'...,make their decisions on where to migrate. This study is supported by an empirical survey of recent Chinese immigrants to Edmonton [Canada].... The findings reveal that when people evaluate different places, they do not necessarily look for the one that generates the highest overall value or utility across all properties.... The study further indicates that the assumption underlying most microeconomic models (that maximizing utility or benefit is the ultimate rule for choosing one location out of several) has not been verified."

An experiment was conducted to assess the effect of using "markall that apply" question instructions on survey reporting aspart of the field test for the Second Follow-up of the NationalEducation Longitudinal Study of 1988 Eighth Graders (NELS:88).Mark-all-that-apply instructions were compared with instructionsasking respondents to indicate "yes" or "no" to each responseoption on responses to three items dispersed throughout thequestionnaire and consisting of different topics and numbersof response options. For the three items, significantly fewerresponse options were selected with the mark-all-that-applyinstructions than with the yes/no instructions, but becauseexternal validity criteria were not available, overreportingto the yes/no instructions cannot be ruled out. Instructiondependentprimacy effects, predicted under the hypothesis that respondentswould engage in more superficial processing when given the mark-all-that-applyinstructions, were not found.  相似文献

Patients may be referred for rehabilitation services with a variety of diagnoses, including stroke, spinal cord injury, brain injury, multiple trauma, orthopedic disorders, arthritis, multiple medical problems, and chronic pain. The goals and endpoints for treatment of these conditions are often unclear. The principles that are described in this article provide a structure for creating efficient and effective rehabilitation treatment plans. These principles can also focus the utilization and peer review processes and can assist in determining medical necessity of rehabilitation services. Part one of this two-part article discusses general principles of cost-effective rehabilitation. Part two, in the December 1995 issue, will focus on individual patient management issues.  相似文献

This article reports on some of the factors that have advanced and impeded hospital progress in moving from inpatient to outpatient surgery. Early on, patients, physicians, and hospital administrators all agreed that outpatient surgery had an intuitive appeal. Patients liked it because they didn't have to go in the hospital. Physicians liked it because they could get in and out of the outpatient surgery center more easily than the main hospital operating room. Administrators recognized the inherent appeal of outpatient procedures but were unable or unwilling to switch services from inpatient to outpatient for a variety of reasons. First, empty hospital beds and diminished scope of inpatient operations are a threat to the power of administrators. Moving surgery from inpatient to outpatient settings reduces inhouse operations. Second, reimbursement incentives were definitely in favor of continued inpatient care long after technology was in place for outpatient care. The third and most critical reason was that cost data on outpatient operations were just not available for making decisions on when to move into the outpatient setting. This review of the literature was intended to document the lack of relevant cost-based accounting. Instead, many other factors that more directly slowed progress were encountered. More than anything, this illustrates the erratic course of progress in health care reform.  相似文献

Coherent decision analysis with inseparable probabilities and utilities   总被引:1,自引:0,他引:1  
This article explores the extent to which a decision maker's probabilities can be measured separately from his/her utilities by observing his/her acceptance of small monetary gambles. Only a partial separation is achieved: the acceptable gambles are partitioned into a set of belief gambles, which reveals probabilities distorted by marginal utilities for money, and a set of preference gambles, which reveals utilities reciprocally distorted by marginal utilities for money. However, the information in these gambles still enables us to solve the decision maker's problem: his/her utility-maximizing decision is the one that avoids arbitrage (i.e., incoherence or Dutch books).  相似文献

A controlled exit-poll experiment on Election Day (November3, 1992) shows that refusals to answer questions and other evasiveforms of responding were significantly lower when respondentswere given a self-administered "secret-ballot" questionnairethan when they were interviewed face-to-face. While there weresome suggestive interactions of this mode-of-data collectioneffect with age and sex, and with the partisan atmosphere ofthe precinct in which the interviews were conducted, they wereborderline in significance, inconsistent in pattern, or difficuitto interpret. More important, comparisons with official electionreturns (the truth) indicated that the secret-ballot techniquewas more accurate than were face-to-face interviews in estimatingthe final outcome on the most socially sensitive of three self-reportedvotes: a vote for or against a tax levy for elderly services.Using a genuine secret ballot in the tradition of the olderGallup preelection polls can thus increase the validity of self-reportsin exit polls today.  相似文献

This article argues that in order to fully understand the geography of labour migration to global cities, it is necessary to consider economic forces in conjunction with mediating socio-cultural influences. Support for this argument is based on an examination of the pattern of migration to Hong Kong, a city which plays a significant role in the world economy.
Reported here are the results of an analysis of recently released 1996 by-census data, and the authors' interviews with foreign domestic workers in Hong Kong. These findings have shown that highly skilled immigrant workers were drawn largely from developed countries, the main sources of inward investment in this city, while less skilled immigrants were drawn from less developed neighbouring labour markets.
While the geographical pattern of immigration followed broadly that predicted from Hong Kong's position in the world economy, the results have revealed that cultural influences such as language and social networks are also important in shaping the economic roles of migrant workers.  相似文献
