The post-1989 change in former Communist societies in East and Central Europe is generally viewed as a double transition involving both marketization (removal of state hegemony over the economy)anddemocratization (move to a Western-style liberal democracy). Data from a nationwide survey of Romania in 1993 demonstrates that Romanians in fact distinguish two reform dimensions—marketization and democratization—as opposed to a single pro-Westernization dimension. Though Romanians distinguish marketization and democratization conceptually, support for reform in both instances is strongest among the same segments of the population: the young, the better educated, men, and those living in cities. Further analysis reveals that the effects of age, gender, and urban residence (but not education) largely wash out once the effects of risk aversion, individualistic ideology, and personal economic expectations are controlled for. Risk aversion is an especially important mediating variable. Men, the young, and those in cities are more likely to support marketization and democratization in large part because they tend to be less averse to risk.  相似文献

Outcome expectancies for gambling were explored in a group of 316 male medium security federal inmates with the multidimensional scaling statistical technique. Sixty-six possible outcomes for gambling were reduced to 16 after a factor analysis determined that 75% of the total variance was accounted for by the first 16 factors (eigenvalues > 0.75). The highest loading item for each factor was utilized in all subsequent analyses. Multidimensional scaling of these 16 items revealed the presence of two primary dimensions (positive-negative and arousing-sedating), corroborating previous research on alcohol outcome expectancies (Rather et al., 1992) and general affective response (Russell, 1980). Significant group (non-gambling, non-problem gambling, possible problem gambling, probable pathological gambling) differences were observed on 12 of the 16 items and on 3 of 4 composite scales (positive expectancies, negative expectancies, arousing expectancies, sedating expectancies).  相似文献

Changes in the structure and provisions of the employment relationship create substantial challenges for the management community. The employer-manager's traditional prerogatives to terminate at will are being eroded in response to changing socioeconomic values that recognize the emergence of an employee's reasonable expectations of job security. The United States lags far behind the international community in protecting these expectations. The authors survey the erosion of the employment-at-will doctrine, and review the concepts of corporate due process and property rights relating to employment. To ensure the institutionalization of this new equity, the authors call on the management community to take the initiative in crafting progressive legislation that strikes a sensible balance between managerial prerogatives and employee expectations of job security.  相似文献

Summary.  The analysis of covariance is a technique that is used to improve the power of a k -sample test by adjusting for concomitant variables. If the end point is the time of survival, and some observations are right censored, the score statistic from the Cox proportional hazards model is the method that is most commonly used to test the equality of conditional hazard functions. In many situations, however, the proportional hazards model assumptions are not satisfied. Specifically, the relative risk function is not time invariant or represented as a log-linear function of the covariates. We propose an asymptotically valid k -sample test statistic to compare conditional hazard functions which does not require the assumption of proportional hazards, a parametric specification of the relative risk function or randomization of group assignment. Simulation results indicate that the performance of this statistic is satisfactory. The methodology is demonstrated on a data set in prostate cancer.  相似文献

A third generation of environmental policy making and risk management will increasingly impose environmental measures, which may give rise to analyzing countervailing risks. Therefore, a comprehensive analysis of all risks associated with the decision alternatives will aid decision-makers in prioritizing alternatives that effectively reduce both target and countervailing risks. Starting with the metaphor of the ripples caused by a stone that is thrown into a pond, we identify 10 types of ripples that symbolize, in our case, risks that deserve closer examination: direct, upstream, downstream, accidental risks, occupational risks, risks due to offsetting behavior, change in disposable income, macro-economic changes, depletion of natural resources, and risks to the manmade environment. Tools to analyze these risks were developed independently and recently have been applied to overlapping fields of application. This suggests that either the tools should be linked in a unified framework for comparative analysis or that the appropriate field of application for single tools should be better understood. The goals of this article are to create a better foundation for the understanding of the nature and coverage of available tools and to identify the remaining gaps. None of the tools is designed to deal with all 10 types of risk. Provided data suggest that, of the 10 types of identified risks, those associated with changes in disposable income may be particularly significant when decision alternatives differ with respect to their effects on disposable income. Finally, the present analysis was limited to analytical questions and did not capture the important role of the decision-making process itself.  相似文献

The current study provides a portrait of emotional-behavioral functioning within a small sample of Vietnam veterans with combat-related posttraumatic stress disorder (PTSD), their partners, and older adolescent and adult children. Veterans, their partners and children reported moderate-low to moderate-high levels of violent behavior. In addition, partner and veteran hostility scores were elevated relative to gender and age matched norms. Partners also reported heightened levels of psychological maltreatment by veterans. Veterans' combat exposure was positively correlated with hostility and violent behavior among children but unrelated to partner variables. Veterans' reports of PTSD symptoms were positively associated with reports of hostility and violence among children, and hostility and general psychological distress among partners. Veterans' violent behavior was also positively correlated with children's violent behavior, but did not yield significant correlations with other child or partner variables. Findings are discussed in relation to prior work and directions for future research are addressed.  相似文献

A meta-analysis of family and twin studies on gambling and problem gambling was initiated in an effort to determine the probable role of genetic factors in high risk wagering. Two twin studies and 17 investigations employing the family history or family study method were included in this meta-analysis. A summation of the 19 studies produced a small but significant overall effect size (weighted = .10, unweighted = .13), with both family (weighted = .12, unweighted = .14) and twin (weighted = .06, unweighted = .05) studies achieving significant individual mean effects. Given the paucity of twin data, further analysis was confined to family studies and revealed a stronger familial effect for the sons of problem gambling fathers than for the daughters of problem gambling mothers and for more severe forms of problem gambling than for less severe forms of problem wagering, and was strongest for high severity problem gambling in males. The implications of these results are discussed.  相似文献
