This study deals with the search for psychological profile(s) that can differentiate levels of leader performance. Although many have rejected the traditional trait theory approach to leadership, others continue to search for meaningful relationships between leader characteristics and leader behavior/effectiveness. Recent promising research focuses on profiles as opposed to individual traits as indicators of leader effectiveness. It is clearly the interaction of certain individual characteristics and situational variables that ultimately predict leader behavior. This requires continued search for person variables that may be relevant to this equation. Work with the 16 Personality Factor scale suggests some promising results. Research in this article focuses on the generation of specification equations that differentiate between high and low performers. The assumption is that there exist unique combinations (profiles) of characteristics that can aid in the prediction of leader performance. This research is an attempt to explore such profiles. Results show that a multitrait profile with weighted scale scores can predict performance. Significant correlations were obtained between 16PF profile scores and overall performance. 相似文献

This paper presents an econometric assessment of the Canadian Wage and Price Control Program. The assessment is specifically designed to determine whether controls have been effective in reducing the long-run inflation rate in Canada. The method of evaluation of the control program is to compare the behavior of inflation under controls to the behavior which would have occurred in the absence of controls. In addition, the paper analyzes inflation in the post-control period to test for the “catch-up” phenomenon. The results suggest that the control program exercised a permanent effect on the inflation rate. 相似文献

This paper presents results of a survey conducted to determine those monographs perceived by accounting academicians to have made the most significant contributions to the accounting literature. Based on responses from 471 academicians from 184 identifiable colleges and universities located in 47 states, a list of the top 15 ranked monographs was compiled. These top-ranked monographs, as selected by a broad cross-section of American academia, could serve as an important source of common knowledge for academicians and graduate students involved in the study of accounting theory. 相似文献

Extending a recent definition, we propose a theorem on the impact of marginal changes in risk on the optimal decision of a risk averse individual. Several micro-economic applications are then provided. 相似文献

The class of games without side payments obtainable from finite trader markets having possibly infinite dimensional commodity spaces, individual compact, convex consumption and production sets, and concave upper-semicontinuous utility functions is considered. It is shown that these market games are precisely the totally balanced games. In fact, each totally balanced game is shown to have both a finite commodity representation and an infinite commodity ‘simple’ representation. 相似文献

Developing a preference-based utility scoring algorithm for the Psoriasis Area Severity Index (PASI)

AbstractIntroduction: It is challenging to identify health state utilities associated with psoriasis because generic preference-based measures may not capture the impact of dermatological symptoms. The Psoriasis Area Severity Index (PASI) is one of the most commonly used psoriasis rating scales in clinical trials. The purpose of this study was to develop a utility scoring algorithm for the PASI.Methods: Forty health states were developed based on PASI scores of 40 clinical trial patients. Health states were valued in time trade-off interviews with UK general population participants. Regression models were conducted to crosswalk from PASI scores to utilities (e.g. OLS linear, random effects, mean, robust, spline, quadratic).Results: A total of 245 participants completed utility interviews (51.4% female; mean age?=?45.3?years). Models predicting utility based on the four PASI location scores (head, upper limbs, trunk, lower limbs) had better fit/accuracy (e.g. R2, mean absolute error [MAE]) than models using the PASI total score. Head/upper limb scores were more strongly associated with utility than trunk/lower limb. The recommended model is the OLS linear model based on the four PASI location scores (R2?=?0.13; MAE?=?0.03). An alternative is recommended for situations when it is necessary to estimate utility based on the PASI total score.Conclusions: The derived scoring algorithm may be used to estimate utilities based on PASI scores of any treatment group with psoriasis. Because the PASI is commonly used in psoriasis clinical trials, this scoring algorithm greatly expands options for quantifying treatment outcomes in cost-effectiveness analyses of psoriasis therapies. Results indicate that psoriasis of the head/upper limbs could be more important than trunk/lower limbs, suggesting reconsideration of the standard PASI scoring approach. 相似文献

The study investigates the effects of personal involvement in a collective risk on the structure of its social representation, and how those effects depend on risk‐related experience. The paper reports an empirical study conducted within the structural approach to the Social Representations Theory. We tested the effects of risk‐related practice (earthquake experience) and of personal involvement in risk on the structure of its social representation. The results showed that the social representation was normative in nature, but became more practically oriented in the group who experienced earthquake. A normative representation is useful in judging risk's attributes; instead, a more functional, or a more practically oriented representation is expected to enable the use of more diversified risk‐related information especially for practical purposes (risk mitigation behaviour). Similarly, the social representation of participants who were highly involved in seismic risk was more structured and more practically oriented. However, this was true only if they possessed risk‐related experience, either through collective (risk culture) or live earthquake experience. Based on these results, a suggestion is made on how to increase the efficiency of prevention campaigns that aim at encouraging collective risk‐mitigation conduct. 相似文献

Extant studies assume that targets’ private ownership mitigates acquirers’ incentives and opportunities to finance acquisitions with inflated stocks. This view stems from the observation that, although the average stock‐for‐stock acquirer's merger announcement return is negative when the target is listed, it is positive when the target is unlisted. Accordingly, extant studies often suggest that announcements of stock‐for‐stock acquisitions of unlisted targets convey favorable private information about the acquirers. However, an analysis of stock‐for‐stock acquirers’ stock performance, abnormal accruals, net operating assets, and insider trading suggests the opposite. Acquirers of unlisted targets are generally more overvalued than acquirers of listed targets. 相似文献
