The question of how to measure the influence of family planning in fertility has been addressed by numerous international scholars. Highlighted briefly here are some of the methods endorsed by United Nations publications and recognized by scholars of various countries: 1) Standardization; 2) John Bongaarts model; 3) Trend analysis; 4) Wishik model; 5) Converse model of Dorothy Nartman; 6) Potter model; 7) Nathan Keyfitz model; 8) "Plural model"; 9) Model analysis. 相似文献

This article examines four issues that need to be explored by the therapist as possible causes of stress for a male couple: stereotypic male roles, stereotypic sexual roles, homophobia, which includes the "coming out" process, and sexual dysfunctions. These issues can cause anxiety and stress, which may in turn cause relationship problems for a male couple. The role of the therapist is clarified and suggestions for treatment are given. 相似文献

Mortality trends in the USSR from the middle of the nineteenth century to the present day are analyzed, with a focus on changes in life expectancy. The authors note that life expectancy increased up to 1964-1965, declined subsequently, and stabilized during the 1980s. Life expectancy has again started to rise since 1985. More detailed analyses of mortality differentials by sex and age and for the rural and urban populations are included. (SUMMARY IN ENG) 相似文献

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...."
