This article integrates two competing perspectives on value orientation. Inglehart's postmaterialism thesis stresses the permanent effects of childhood experience in which economic deprivation leads to materialism in adult life. The human development perspective, in contrast, emphasizes the evolution of a person's value system as life-cycle development unfolds new circumstances and possibilities. We adopt a developmental framework to test claims from these two perspectives. On the basis of micro-level data, we compare the materialistic values of two historically and culturally different Chinese societies, Hong Kong and Guangzhou. Findings support Inglehart's assertions that childhood experience has lasting effects and that rapid social changes create birth cohort differences in materialistic concerns. But life-cycle developments, such as education, marriage, and current social status, are equally important in influencing a person's value orientation. Both perspectives see only part of the picture, and an integrated approach is needed to better understand how people construct and maintain their value system.  相似文献

Samuels interviewed Dimen in lieu of a book review for her Sexuality, Intimacy, Power. The interview was unstructured and dialogical and covered the following main topics: (a) professional issues in the field of psychoanalysis such as the relation of theory to practice and reflections on the nature and content of trainings in psychoanalysis; (b) issues in the broad areas of sexuality and gender including the question of moral relativism with respect to sexual behaviors historically designated as “perverse” and considerations of masculinity, femininity, and patriarchy; (c) intellectual considerations such as the relations between anthropology and psychoanalysis and the as yet indeterminate nature of the discipline of psychoanalysis, neither art nor science and not a hybrid of the two; and (d) the political, social, and cultural contexts within which psychoanalytic endeavors including the interview itself are taking place.  相似文献

Abstract

The central theme of this article is performance management, defined as activities of organizations aimed at an effective and efficient use of their human resources. The organization focused on in particular is the hospital. Three principles taken from motivation theory are dealt with which are basic to performance management: goal setting, feedback and reinforcement. Next, a recently developed procedure (Pritchard 1990, Pritchard et al. 1988, 1989) for the design of performance management systems is described. This procedure, ProMES: Productivity Measurement and Enhancement Systems, is explained using a team of ward nurses as a hypothetical example. In addition to the nursing wards example, other potential applications of the ProMES technique to several hospitals areas are mentioned. Finally, some conditions that should be fulfilled in order to successfully start a ProMES project are discussed.  相似文献

In this study, we develop nonparametric analysis of deviance tools for generalized partially linear models based on local polynomial fitting. Assuming a canonical link, we propose expressions for both local and global analysis of deviance, which admit an additivity property that reduces to analysis of variance decompositions in the Gaussian case. Chi-square tests based on integrated likelihood functions are proposed to formally test whether the nonparametric term is significant. Simulation results are shown to illustrate the proposed chi-square tests and to compare them with an existing procedure based on penalized splines. The methodology is applied to German Bundesbank Federal Reserve data.  相似文献

In this article, interval estimates of Clements' process capability index are studied through bootstrapping when the underlying distribution is Inverse Gaussian. The standard bootstrap, the percentile bootstrap, and the bias-corrected percentile bootstrap confidence intervals are compared.  相似文献

Box–Cox together with our newly proposed transformation were implemented in three different real world empirical problems to alleviate noisy and the volatility effect of them. Consequently, a new domain was constructed. Subsequently, universe of discourse for transformed data was established and an approach for calculating effective length of the intervals was then proposed. Considering the steps above, the initial forecasts were performed using frequently used fuzzy time series (FTS) methods on transformed data. Final forecasts were retrieved from initial forecasted values by proper inverse operation. Comparisons of the results demonstrate that the proposed method produced more accurate forecasts compared with existing FTS on original data.  相似文献

This paper presents three small sample tests for testing the heteroscedasticity among regression disturbances. The power of these tests are compared with two of the leading tests for this hypothesis, one by Goldfeld and Quandt [5] and the other by Theil [17]. We also provide a heuristic method of selecting the number of middle observations to be deleted for the Goldfeld-Quandt type of tests.  相似文献

Late-life stressors often require individuals to make substantial alterations in behavior and lifestyle and can affect their overall health and well-being. Relocation is a significant life stress, regardless of age. The primary aim of this study is to elucidate the push-pull factors associated with moving into congregate senior housing. The secondary aim is to investigate the decision-making processes and stresses associated with moving into a congregate living environment. Interviews were conducted with 26 women who were new residents in congregate senior housing. Relocation, as expected, was considered to be stressful, although individual differences were found among perceptions of relocation stresses. Women who had made the decision to relocate on their own showed evidence of better psychosocial well-being at the time of the move. One-quarter of the sample chose to move to provide care to another person. As the options for senior housing continue to evolve and the number of adults reaching advanced age continues to increase, it is important to understand the factors that contribute to successful adaptation. This knowledge will enable facility administrators to implement programs and procedures to assist incoming residents with acclimating to their new homes.  相似文献

The German Corporate Tax Reform Act of 2008 requires an adjustment of classic valuation concepts because it limits interest deduction from taxable income depending on the operating performance of the company. By using time- and state-contingent discount rates in a risk-neutral valuation with predetermined debt levels, a theoretically sound valuation result is obtained. However, a modified APV-concept which assumes deterministic debt over the planning horizon and constant leverage in the terminal value phase also yields consistent valuation results when two types of tax shields with different levels of risk are distinguished.  相似文献
