The personal values systems of 884 public- and private-sectormanagers are compared. From that comparison inferences are drawnregarding the ethos of each sector, and potential implicationsfor managers are discussed. Although the personal-values systemsin the two sectors are quite similar, results reflect a public-sectorethos that is significantly higher in Delayed Gratificationand Self-Expansion and a private-sector ethos that is significantlyhigher in Competence, Personal Orientation, and Family Security.In addition, this study furthers the view that the personal-valuessystems of male and female managers within a given employmentsector are not significantly different.  相似文献

In preparation for planning counseling and mental health services at Columbia University, the authors conducted a mental health needs assessment survey that sampled representative numbers of students. Respondents were most concerned about academic and school-related issues, followed by concerns in the area of love relationships. Multiple regression analysis revealed certain subgroups that were more likely to have these concerns and certain health and mental health problems that were significantly associated with these concerns. The study identified serious psychological problems, including suicidal/homicidal thoughts and sexual abuse, and surveyed respondents' treatment preferences. Finally, the authors discuss how the study findings contributed to sharpening and expanding focus on different aspects of program development in the collaboration between mental health and health education.  相似文献

This paper discusses the results of empirical research examining history teachers’ opinions on teaching recent history, and on the revocation of a moratorium on teaching former Yugoslavia’s recent history in Serbian minority schools in the Croatian Danube region. The research was conducted in 2003, involving a sample of 29 primary and secondary history teachers in both the majority and minority programmes in the two counties affected by the moratorium. The post‐war divide is evident from the differences in teachers’ opinions regarding the moratorium’s revocation and the presentation of minority history in history teaching. On a general level however, when the history of the Croats and Serbs was not discussed, most of the teachers advocated a liberal concept of history teaching.  相似文献

In this paper we present improvements to one of the most recent and fastest branch-and-bound algorithm for the maximum clique problem—MCS algorithm by Tomita et al. (Proceedings of the 4th international conference on Algorithms and Computation, WALCOM’10, pp. 191–203, 2010). The suggested improvements include: incorporating of an efficient heuristic returning a high-quality initial solution, fast detection of clique vertices in a set of candidates, better initial colouring, and avoiding dynamic memory allocation. Our computational study shows some impressive results, mainly we have solved p_hat1000-3 benchmark instance which is intractable for MCS algorithm and got speedups of 7, 3000, and 13000 times for gen400_p0.9_55, gen400_p0.9_65, and gen400_p0.9_75 instances correspondingly.  相似文献

Although several authors have indicated that the median test has low power in small samples, it continues to be presented in many statistical textbooks, included in a number of popular statistical software packages, and used in a variety of application areas. We present results of a power simulation study that shows that the median test has noticeably lower power, even for the double exponential distribution for which it is asymptotically most powerful, than other readily available rank tests. We suggest that the median test be “retired” from routine use and recommend alternative rank tests that have superior power over a relatively large family of symmetric distributions.  相似文献

The 7-item adult version of the Personal Wellbeing scale (Cummins et al. Social Indic Res 64:159?C190, 2003) was administered to two samples of adolescents aged 12?C16 in Brazil (N?=?1,588) and Spain (N?=?2,900), and to a sample of adolescents aged 14?C16 in Chile (N?=?843). The results obtained were analyzed to determine its psychometric characteristics when used with adolescents in the three different countries and to check whether two additional items would improve its qualities. Results reveal that the new PWI-9 version worked well with the adolescents in the three countries, improving some of the qualities of the PWI-7. One of the added items, satisfaction with oneself, appears to be a major contributor to unique explained variance when regressed on the single-item of overall life satisfaction (OLS). The model we present using structural equations shows good fit statistics for the factor structure, with both 7 and 9 items. Separate in-country analyses demonstrate that cultural context has a strong influence on correlations and saturations between the studied variables and also on the explained variance. Probably related to this fact, the Model fit structure is good in Brazil (with a low PWI variance accounted for by its predictors) and Spain (medium), but rather modest in Chile, where data show a high proportion of the PWI variance accounted for by its predictors. However, a multi-group factor analysis among the three countries restricting saturations to 1 in each country in order to make data comparable across countries still show a good fit of the proposed model for both PWI-7 and PWI-9.  相似文献

This study examines, within the context of a model developed recently by Farber and Katz, the role of expectations, uncertainty, and costs on the incentive to bargain. It is shown that experience with a compulsory arbitration process can best be viewed as creating opposing effects on the frequency of use. While decreased uncertainty will reduce incentives to bargain, the convergence of expectations can work either to increase or decrease arbitration usage over time. Empirical evidence, while suggestive, is found to be too limited to draw strong conclusions on the relative magnitude of these effects. In addition, the paper incorporates arbitration costs into the bargaining model, and the effects of costs on arbitration usage and on the outcomes of negotiated settlements are examined. Available evidence on the magnitude of direct arbitration costs is then summarized. Because these costs are often low and provide little incentive to bargain, the authors suggest a policy approach for levying costs on the parties. The authors thank Vincent Crawford, Henry Farber, Thomas Kochan, and James Bennett for helpful comments and Pamela Marett for research assistance.  相似文献

In response to increased consumer demand, state governments are publishing more detailed information about the quality of nursing homes. In 2002, Ohio legislation mandated the publication of a Long-Term Care Consumer Guide that included information on nursing home resident and family satisfaction surveys. Using the 2002 Ohio Nursing Home Resident Satisfaction Survey as an example, this article addresses two research questions: (1) how can statewide resident face-to-face satisfaction interviews be implemented to maximize participation of residents and facilities and produce reliable and valid results, and (2) how satisfied are residents with their nursing home experiences, overall and by level of cognitive function.  相似文献

Skew‐symmetric families of distributions such as the skew‐normal and skew‐t represent supersets of the normal and t distributions, and they exhibit richer classes of extremal behaviour. By defining a non‐stationary skew‐normal process, which allows the easy handling of positive definite, non‐stationary covariance functions, we derive a new family of max‐stable processes – the extremal skew‐t process. This process is a superset of non‐stationary processes that include the stationary extremal‐t processes. We provide the spectral representation and the resulting angular densities of the extremal skew‐t process and illustrate its practical implementation.  相似文献
