This paper deals with benchmark‐based portfolio choice for buy‐and‐hold strategies of investing. Multiple benchmarks for returns are considered, which is more realistic than taking a unique benchmark – a unique aspiration difficult to select in practice among the various aspirations for returns that the investor has in mind. Portfolio selection with multiple benchmarks leads to a multi‐objective problem, which is addressed by mean value – stochastic goal programming. In particular, two benchmarks are considered, which involves two goals. Weights for goals depend on investor's preferences and Arrow's absolute risk aversion coefficients. An efficient frontier of portfolios is obtained. Advantages of this stochastic method in our context are as follows: (i) Mean value‐stochastic goal programming relies on classical utility theory under uncertainty and Arrow's absolute risk aversion, which ensures soundness and strictness, and (ii) the numerical model is easily solved by using available software such as mean–variance software. Numerical results are tabulated and discussed. Copyright © 2011 John Wiley & Sons, Ltd.  相似文献

In this article, the author conceptualizes the counseling process and its outcome by comparing it metaphorically to Freud's psychosexual stage conception of personality development. Specifically, he focuses on resemblances between the oral, anal, phallic, latency, and genital stages of both Freud's conception and the counseling process. Suggestive of the heuristic quality of metaphorical comparisons, new meanings can be drawn from these resemblances, leading to fresh insight into the nature of the counseling relationship.  相似文献

In this 257-participant study (76% female; mean age: 44.84), we examined two ideas that are widespread among burnout researchers: (a) the idea that burnout is primarily related to occupational-level factors; and (b) the idea that burnout should be considered a sentinel indicator in research on negative occupational outcomes. We investigated the links between burnout and a series of generic and work-related variables, namely, depressive symptoms, neuroticism, extraversion, effort-reward imbalance in the job [ERI], social support at work (SSW), and turnover intention. Burnout was assessed with the Shirom-Melamed Burnout Measure, depressive symptoms with the PHQ-9, neuroticism and extraversion with the NEO-Five Factor Inventory, ERI with the 10-item version of the Effort-Reward Imbalance Questionnaire, SSW with the Job Content Questionnaire, and turnover intention with a dedicated 3-item measure. Correlation, multiple regression, and relative weight analyses were conducted. Burnout was not found to be more strongly linked to organizational and work-contextualized variables than to personality traits. In addition, turnover intention was not associated to a greater extent with burnout than with ERI. Burnout and depressive symptoms were highly correlated and exhibited overlapping nomological networks. Overall, our findings question the way burnout has been generally conceived.  相似文献

Many researchers provide praise for complying with demands during the escape condition of the functional analysis (FA). However, praise may function as a reinforcer for some individuals which may reduce the aversiveness of task presentation or increase behavior that competes with problem behavior (e.g., compliance with demands). In general, this may result in lower or less stable levels of problem behavior and decrease the efficiency of the FA. Thus, the purpose of the current study was to evaluate some effects of praise on the rate of problem behavior and compliance during the escape condition of the FA in children diagnosed with autism spectrum disorder. We found that praise did not affect the rate of problem behavior but did increase compliance in three of five subjects. The results of the study and implications for the assessment of problem behavior are discussed.  相似文献

Research has suggested that military spouses experience increased depressive symptoms and parenting stress during a military member's deployment. A relationship between maternal depressive symptoms, parenting stress, and child attachment security has been found in the general population, as has an indication that social support may provide a buffering effect. While there appears to be an association between the emotional well‐being of military spouses and child emotional well‐being during deployment, data are limited regarding the association between maternal emotional well‐being and child attachment security. The current study explores the association between deployment status and child attachment to the nonmilitary parent (i.e., the mother in this study) in a sample of 68 Canadian military families. Results revealed a significant impact of deployment status on maternal depressive symptoms and on quality of child attachment. The impact of deployment status on attachment was not mediated through the maternal variables, and despite a main effect of social support on the maternal variables, there was no moderating effect. Thus, our results suggest that deployment may affect child attachment independently of maternal well‐being.  相似文献

This paper describes the development and validation of an inventory to uncover youths' experiences in their neighbourhoods. The Neighbourhood Youth Inventory (NYI) was developed from conversations with youths in Grades 7, 9 and 11. This paper reports the psychometric analyses of the NYI. Responses from 934 youths (511 urban, 423 rural) to the NYI resulted in a four‐factor solution. This solution was stable across responses from youths in Grades 7, 9 and 11, and for urban and rural youths. Cronbach alphas ranged from 0.64 to 0.94. Construct, convergent and discriminant validity of the NYI subscales are demonstrated. Using the NYI we will be able to assess youths' experiences within their neighbourhoods, which may contribute to a more ecological understanding of healthy developmental outcomes beyond family, peer and school environments.
