"This paper proposes a conceptual framework for analyzing migration as a household event and presents two public use microdata applications of this approach for out-migrants from New York City. The distribution of single- and multi-origin households by race and Hispanic origin permits a more rigorous analysis of household migration differentials....and the disaggregation of household members by migration status provides insight into the household outcomes of the migration process...."

The author discusses the effect of remittances from workers in oil-producing states in the Arab world on macroeconomic development patterns in non-oil-producing regions. Consideration is given to the impact of remittances on consumption and domestic growth and their interrelationships with foreign exchange. (SUMMARY IN FRE AND SPA)  相似文献

Subjects imagined situations in which they reported enjoying themselves either alone or with others. Electromyographic (EMG) activity was recorded bilaterally from regions overlying thezygomatic major muscles responsible for smiling. Controlling for equal rated happiness in the two conditions, subjects showed more smiling in high-sociality than low-sociality imagery. In confirming imaginary audience effects during imagery, these data corroborate hypotheses that solitary facial displays are mediated by the presence of imaginary interactants, and suggest caution in employing them as measures of felt emotion.Avery Gilbert and Amy Jaffey had compelling insights throughout the course of study. We thank Paul Ekman, Carroll Izard, and Paul Rozin for extensive comments on earlier drafts. We also thank Bernard Apfelbaum, Jon Baron, Janet Bavelas, John Cacioppo, Linda Camras, Dean Delis, Rob DeRubeis, Alan Fiske, Stephen Fowler, Greg McHugo, Harriet Oster, David Premack, W. John Smith, and David Williams for their valuable comments and suggestions.  相似文献

Doctors are not health care providers, and medicine is not a commodity. To practice medicine well, the doctor must attend to each patient as a whole person and be faithful in giving care when cure is not possible.  相似文献

The problems that people experience in social roles can be regarded as either causes or consequences of psychological symptoms. To reflect one of these possibilities, Pearlin et al. (1981) developed measures of "role strains" which are considered sources of psychopathology. To reflect the other position, Dohrenwend et al. (1981) constructed measures of "role functioning" which are seen as consequences of psychopathology. We show that the measures developed by these two teams of investigators are similar in content and show substantial empirical overlap despite the different meanings attributed to them. In an effort to understand whether these highly correlated measures assess, "role strain" or "role functioning," we conduct an exploratory analysis of marital and housework role problems, using a small panel sample of New York City residents. Specifically, we use instrumental variables to identify reciprocal effects between psychological distress and each role area. We find that the relationship between housework role problems and distress is more consistent with Pearlin et al.'s interpretation, whereas the relationship between marital problems and distress is more consistent with that of Dohrenwend et al. Investigators interested in measuring either role strain or role functioning must bear in mind the strong possibility of contamination from the other construct.  相似文献

A recent American survey of attitudes toward societal multiculturalism vs. assimilation has found surprisingly widespread support for maintaining heritage cultures not only among immigrant minority groups but also among most subsamples of majority host groups, black and white. Working-class whites are the one exception. This pilot study explores the same attitude domain in a contrasting European setting. Randomly selected samples of middle- and working-class families (a mother, father, and teenage son or daughter) from a small city in France were interviewed. As a group, they were neutral to slightly favorable to immigrants maintaining heritage cultures and languages rather than losing them through assimilation. On measures of attitudes toward specific immigrant groups, there were marked intergroup dyfferunces with Maghrebian Arabs rated leist favorably and Southeast Asians, the model immigrants, most favorably. Comparisons of subgroups of respondents who varied in terms of (a) political left-right orientation, (b) social class standing, (c) degree of religiosity, and (d) generational level provide the base for a more general discussion of cultural assimilation and multiculturalism.  相似文献

Originally presented to the Society of Home Health Care Management of the American College of Physician Executives at its November 16, 1993, meeting in Tucson, Ariz., the program described in this article was the winner of the College's 1994 Innovations Award in Medical Quality Management, sponsored by Merck Sharp & Dohme. The program shows the potential of case management for both improvement in the quality of care and containment of costs for a managed care population with a substantial Medicaid segment. This article is part of a continuing series on innovative programs in home health care.  相似文献
