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

Research on firm search stresses the need for firms to adapt and align concurrently with their environment to optimize the ability to sense and seize opportunities for sustained performance. We postulate resource scarcity as an important contingency factor for the search-performance relationship, and assess its joint influence with high and low dynamism. Using a dataset spanning 23 years, we examine the performance implications of combinations of internal and external exploratory and exploitative search in resource-scarce environments, under conditions of high and low dynamism. We find that resource scarcity is an important condition for performance stemming from exploratory and exploitative search: even under conditions that involve low dynamism, but joined with resource scarcity, firms may benefit from pursuing exploratory and exploitative knowledge simultaneously.  相似文献

色彩是当代电影艺术最重要的艺术语言和表达方式之一.色彩在画面叙事和视觉美学的自我构建中,体现了当代影视和现代艺术的自我革新和体式变革,也体现了人类审美的时代追求与心理演进.新时代的审美文化在全球化和多元化的历史进程中,尤其关注色彩和色调在美术创作中的艺术构图、视界成型和哲理引导.通过研究电影色彩的叙事手法进一步探寻电影色彩的形式、时代、情感、伦理、原型的审美价值以及对审美公众的审美意义,有助于充分发挥电影色彩的价值,进一步探索电影创作的规律.  相似文献

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
