The purposes of this study were to obtain data on the Children's Manifest Anxiety Scale (CMAS) administered to children in an Appalachian area, to compare these data with appropriate studies reported in the literature for other groups of children in the United States, and to discuss results in terms of child-rearing practices. The CMAS was administered to 176 fifth and sixth grade children from families of low socioeconomic level in a rural Appalachian area of East Tennessee. Mean scores were higher than for most groups of middle-class Midwest children reported in the literature, especially for fifth grade girls, but were commensurate with reported scores of children from a Southeastern area, black children, and a psychiatric outpatient group in Minnesota. Results of an item analysis and chi-square analysis of sex differences were compared with a St. Louis study. Findings are discussed in terms of child-rearing practices in Appalachia since reports of cross-cultural CMAS studies have stressed this aspect when reporting comparative data. 相似文献

Organizational leaders face environmental challenges and pressures that put them under ethical risk. Navigating this ethical risk is demanding given the dynamics of contemporary organizations. Traditional models of ethical decision-making (EDM) are an inadequate framework for understanding how leaders respond to ethical dilemmas under conditions of uncertainty and equivocality. Sensemaking models more accurately illustrate leader EDM and account for individual, social, and environmental constraints. Using the sensemaking approach as a foundation, previous EDM models are revised and extended to comprise a conceptual model of leader EDM. Moreover, the underlying factors in the model are highlighted—constraints and strategies. Four trainable, compensatory strategies (emotion regulation, self-reflection, forecasting, and information integration) are proposed and described that aid leaders in navigating ethical dilemmas in organizations. Empirical examinations demonstrate that tactical application of the strategies may aid leaders in making sense of complex and ambiguous ethical dilemmas and promote ethical behavior. Compensatory tactics such as these should be central to organizational ethics initiatives at the leader level. 相似文献

In this paper, we introduce a new approach for finding robust portfolios when there is model uncertainty. It differs from the usual worst‐case approach in that a (dynamic) portfolio is evaluated not only by its performance when there is an adversarial opponent (“nature”), but also by its performance relative to a stochastic benchmark. The benchmark corresponds to the wealth of a fictitious benchmark investor who invests optimally given knowledge of the model chosen by nature, so in this regard, our objective has the flavor of min–max regret. This relative performance approach has several important properties: (i) optimal portfolios seek to perform well over the entire range of models and not just the worst case, and hence are less pessimistic than those obtained from the usual worst‐case approach; (ii) the dynamic problem reduces to a convex static optimization problem under reasonable choices of the benchmark portfolio for important classes of models including ambiguous jump‐diffusions; and (iii) this static problem is dual to a Bayesian version of a single period asset allocation problem where the prior on the unknown parameters (for the dual problem) correspond to the Lagrange multipliers in this duality relationship. This dual static problem can be interpreted as a less pessimistic alternative to the single period worst‐case Markowitz problem. More generally, this duality suggests that learning and robustness are closely related when benchmarked objectives are used. 相似文献

Web-based distance learning is an up and coming form of education. Web-based education delivered via a Web browser through the Internet has been found to be less expensive, more efficient, and sometimes more effective than classroom training. In the distance learning environment, the traditional \"lecture and chalkboard\" classroom pedagogy is completely absent. The virtual classroom becomes an \"active learning\" environment in which students, while utilizing technology, are able to discuss health administration concepts, analyze cases, work exercises, and discuss and share these interactively with both the instructor and fellow classmates. This method of Health Administration Education encourages students to learn from each other and promotes the open exchange of ideas and experiences. It does not require working students to put their careers on hold while they continue their studies. In this paper, we explore the opportunities and challenges of delivering web-based Health Administration courses via the Internet. Included is a discussion of the design, development, and delivery of a distance learning, web-based Health Administration Education system. 相似文献

Little is known about the form and or magnitude of compensation provided university-based scientists working on firm R&D. This is unfortunate, given the important role that university-based scientists play in R&D, and the growing literature concerning compensation and innovation. This paper sheds some light on these issues by examining the compensation of university-based scientists involved with 52 biotech firms that made an initial public offering between March of 1990 and November of 1992. Although the stock holdings of the university scientists are of particular interest, additional forms of compensation received by the scientists are also examined.We find that approximately 10 percent of the university-based scientists affiliated with these companies hold sufficient options or stock to require disclosure at the time of the public offering. A far larger proportion has an equity position in the firm. In many instances the scientists also receive consulting fees or salary from the firm and enter into licensing agreements with the firm. In addition to providing information concerning the compensation of university-based scientists, the empirical work suggests that the rewards to science can be significantly greater than previous work would suggest. 相似文献

The trade-off between accuracy and complexity is a common issue faced in farm systems analysis. To provide insights into the importance of representing weather-year sequence in farm modelling, two whole-farm optimisation models are constructed and applied to a mixed enterprise farming system in a subregion of Western Australia. The frameworks are (i) four-stage single-sequence stochastic programming with recourse (4-SPR) to capture weather-year variation and management tactics tailored to each weather-year and (ii) eight-stage multi-sequence stochastic programming with recourse (8-SPR) to outline weather-year sequences and management tactics tailored to particular weather-year sequences. Results show that single-year stochastic programming generates similar expected profit and strategic management as multi-year stochastic programming. However, optimal tactical farm management is affected by the outcome of the previous year. Tactical decision-making in response to the outcome of the preceding weather-year increases profitability by 14%. Technology changes over the last decade, particularly the increase in computer speed and computational power, increase the ease of construction and application of the 4-SPR and 8-SPR frameworks. Nonetheless, choosing which framework is best to apply to a particular issue or opportunity remains a challenge. 相似文献
