Neugebauer JE 《Physician executive》1991,17(4):30-31
At the end of May, the U.S. Supreme Court allowed an antitrust claim by a physician against a hospital for an allegedly improper peer review proceeding. Previously, hospitals were allowed to defend against antitrust claims regarding a peer review decision involving one physician on the grounds that the activities did not affect interstate commerce. The Supreme Court has apparently removed this defense by letting stand a Court of Appeals decision allowing a physician's antitrust claim against a hospital that has suspended his privileges. 相似文献

To change from punitive and legalistic QA to positive and productive CQI, both attitudes and methods must change. This is a difficult challenge, but potential rewards for both the organization and its individual members suggest that the effort is worthwhile and deserves high priority. Members of the executive/management team will likely turn to physician executives for guidance on how to proceed. 相似文献

RACE-OF-INTERVIEWER EFFECTS IN A PREELECTION POLL VIRGINIA 1989 总被引:1,自引:0,他引:1
All published preelection surveys of the 1989 Virginia gubernatorialcontest overestimated the vote share of the black candidateand eventual victor, Douglas Wilder. We offer a "social desirability"interpretation of the polls' inaccuracies and hypothesize thatclaiming support for Wilder was the socially desirable responsefor some whites, especially when the interviewer was black.We show a race-of-interviewer effect on the vote intention ofwhite respondents of 8–11 percentage points in a preelectionsurvey of Virginia voters. The effects were greatest among whiteDemocrats and among whites who were more uncertain of theirvote intention. We discuss the implications of these findingsfor race-of-interviewer research and for improving the accuracyof preelection forecasts in contests with black and white opposingcandidates. 相似文献

"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 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

Several countries have attempted to change human fertility through economic incentives. This paper presents simple mathematical models of the participation of couples in a locally funded program of economic incentives. The models take as a springboard China's one-child program. Localities with low per capita incentives attract few couples to the program, while localities with high incentives attract many couples at first, but the value of the benefits is then watered down. The models show that participation in the program may persistently oscillate or may decay to a stationary level. Which behavior occurs is determined by whether there are decreasing, constant, or increasing returns in the rates of participation in response to successive equal increments in the incentive offered, and by the extent to which prospective parents learn from experience with past oscillations in the incentives. The models raise many empirical questions about the dynamics of incentive programs. 相似文献
