Beginning in the late 1970s, a series of reforms to improve industrial productivity were implemented in China. We estimate changes in productivity growth and identify its sources in the post-reform period 1980-85. Our work is based on the newest and most comprehensive data set available on Chinese industrial activities. Productivity growth estimates are shown to be strongly affected by output specification. Overall, we find sharp increases in productivity growth in the 1984-85 period as compared to the 1980-84 period. Collective and private enterprises show higher output and productivity gains than do state-owned enterprises. 相似文献

1. The significant others of persons with AIDS, whether they assume the role of primary caregiver or not, have a number of unique experiences, concerns, and needs specifically related to their situations. 2. During the initial period following the diagnosis of a loved one, the significant others indicated their primary needs as sensitivity to their situations, assistance in securing appropriate information, and psychological support in dealing with uncertainty, and a general sense of dread. 3. Other common concerns and needs expressed by the significant others included support and reassurance, assistance in adjusting to a myriad of personal relationship changes, and help in meeting needs for active involvement in some form of AIDS-related work. 相似文献

Sixty-one newly arrived war-wounded refugees were interviewed about their background and flight while treated at the Medical Center for Refugees, University Hospital, Linköping, Sweden. They came from 9 countries in Asia, Africa and Latin America. Spinal cord injuries, nerve lesions, amputations and fractures were the most frequent injuries. The group was heavily burdened with regard to factors that might be of significance for wellbeing and integration in Swedish society: torture (51%), imprisonment (49%), loss of kin in war (62%), difficulties while growing up (54%), little or no schooling (48%), not having made the decision to flee oneself (46%) and having to leave the family behind (90%). This study is a first step in a longitudinal research project to shed light upon the situation of war-wounded refugees on arrival in Sweden and after 2 years. 相似文献

To disentangle clients from a social service network that has turned into a web, the author suggests a method: case conferences that include staff members of involved services, and a role: the systems-oriented case manager. As the coordinator of the client's social service network, the case manager would mediate the overt and convert conflicts that often exist among the professionals who are involved simultaneously with the client. 相似文献

The authors propose a weighted likelihood concept for the estimation of parameters in natural exponential families with quadratic variance. They apply the results to both simulated and real data. 相似文献

A class of distribution-free tests based on two matched pairs is considered for testing independence against positive quadrant
dependence. The class of tests proposed by Kochar and Gupta (1990) is a member of the proposed class. The performance of the
proposed class is evaluated in terms of Pitman asymptotic relative efficiency for Block-Basu (1974) model and Woodworth family
of distributions. The small sample performance of few members of the proposed class is also studied by finding empirical powers.
Unbiasedness and consistency of the proposed class of tests have been established. 相似文献

An overview of risk-adjusted charts 总被引:2,自引:1,他引:1

Summary. The paper provides an overview of risk-adjusted charts, with examples based on two data sets: the first consisting of outcomes following cardiac surgery and patient factors contributing to the Parsonnet score; the second being age–sex-adjusted death-rates per year under a single general practitioner. Charts presented include the cumulative sum (CUSUM), resetting sequential probability ratio test, the sets method and Shewhart chart. Comparisons between the charts are made. Estimation of the process parameter and two-sided charts are also discussed. The CUSUM is found to be the least efficient, under the average run length (ARL) criterion, of the resetting sequential probability ratio test class of charts, but the ARL criterion is thought not to be sensible for comparisons within that class. An empirical comparison of the sets method and CUSUM, for binary data, shows that the sets method is more efficient when the in-control ARL is small and more efficient for a slightly larger range of in-control ARLs when the change in parameter being tested for is larger. The Shewart p -chart is found to be less efficient than the CUSUM even when the change in parameter being tested for is large. 相似文献
