An initial test and validation of a model predicting perceived organizational citizenship behaviors (OCBs) of lesbian and gay employees were conducted using structural equation modeling. The proposed structural model demonstrated acceptable goodness of fit and structural invariance across 2 samples (ns = 311 and 295), which suggested that altruistic OCB performance is precipitated by workplace outness. Furthermore, stigmatization salience and organizational climate for heterosexism predict levels of workplace outness. Organizational climate for heterosexism is negatively related to stigmatization salience. When the model was tested on 2 samples, all structural paths except 1 were significant.  相似文献

A two-sided sequential confidence interval is suggested for the number of equally probable cells in a given multinomial population with prescribed width and confidence coefficient. We establish large-sample properties of the fixed-width confidence interval procedure using a normal approximation, and some comparisons are made. In addition, a simulation study is carried out in order to investigate the finite sample behaviour of the suggested sequential interval estimation procedure.  相似文献

Results from the 1982 census show great progress has been made in the field of family planning because of close cooperation between the people and the government. Under the influence of the high birth rate in the 1950s and 1960s, a large number of youths are reaching the age for marriage each year, and they are bringing heavy pressure on the population growth. As a result of this situation, family planning work is still urgently needed. A great difference exists between cities and rural areas in family planning work. Economic conditions, cultural and educational levels, occupational characteristics, living environments, and concepts of population growth have contributed to this difference. Henceforth, special emphasis should be placed on family planning work in rural areas, so that the large scale population groth in the countryside may be brought under control. In areas of scientific management, propaganda and education, and technical measures for family planning, modern and and progressive methods should be used in order to reach the national goal of controlling population growth.  相似文献

For a long time, the Dongxiang nationality has lived in the area of Dongxiang, which is a part of Gu Hezhou in Gansu Province. Among the various minorities in China, the Dongxiang people has been noted for their small population. In recent years, however, their population growth rate has been very high. Statistics show their annual population growth rate was 13.5% in 1970 and 32.8% in 1980. This situation is caused mainly by the young age of the population (young persons under the age of 19 constitute 55.7% of the entire population). Because of the popularity of Islam among the people, the custom of early marriage and having children at an early age has long been a tradition. Rapid population growth has created numerous problems. Food production has been unable to keep up with the speed of the population growth, and economic development cannot satisfy the needs of the rapid growing population. The Dongxiang people are physically healthy and strong, and marriages between close relatives is prohibited. Because of the backward condition in education and culture, efforts to promote the quality of the Dongxiang population have remained slow and ineffective. Starting in 1974, the local government in Dongxiang launched extensive birth control projects and positive results have been achieved. At the present time, about 62% of its population have taken birth control measures, and the natural population growth rate dropped to 15.34% in 1982.  相似文献

The model presented in this paper assumes that a uniform lot size is produced through a series of manufacturing stages, with a single set-up and without interruption at each stage. Transportation of partial lots, called batches, is allowed between stages after the whole batch is completed. The batch sizes must be equal at any particular stage, but the optimal number of equal-sized batches may differ across stages. Of course, the set-up costs, the inventory-holding costs and the transportation costs influence both the optimal batch-sizes at the various stages and the uniform lot size. An optimization method for this deterministic model is developed and is illustrated by an example.  相似文献

Bureaucratic discretion is a fundamental feature of social provision,one that presents enduring difficulties for management. In general,management reform has taken two, divergent paths. One, utilizingthe familiar public bureaucratic model, seeks to control discretionthrough hierarchical command structures and standardization.The other, utilizing decentralization and privatization, regulatesand relocates discretion, using incentive structures associatedwith market or quasi-market institutions. However, it may bethat discretion will prove to be as problematic for the newpublic management (NPM) as it was for the old. This articleoffers a critical political history of management reformism,reviewing efforts to reorganize the public welfare provisionby applying new public management models to old public bureaucracyproblems. It considers the dynamics of bureaucratic discretionand reform not only as a problem of public management but aspart of the contested politics of social policymaking.  相似文献
