How should the defense activities of allies be aggregated to determine the alliance-wide level of defense? Two alternative modelsbest shot and weakest linkare contrasted with simple summation of defense spending or manpower for aggregating allies' defense efforts. We extend the joint product model to include these methods of aggregation, and devise an empirical procedure to test between best-shot and weakest -link models. We apply this test to four alliances: Triple Alliance (1880–1914), Triple Entente (1880–1914), Warsaw Pact (1963–1987), and NATO (1961–1987). The testing procedure can be applied to other collective choice situations.  相似文献

Abstract

Based on the value of children theory, the purpose of this study was to develop and establish the factor structure and internal consistency reliability of the Advantages of Children Scale (ACS), a self-report measure of a modification of Hoffman and Hoffman’s value scheme of the psychological needs children meet for their parents. Data were collected from 685 emerging adult men identifying as Latino or Caucasian who were not parents. Results of the confirmatory factor analysis found a good fit for the six hypothesized subscales on the ACS: connectedness, expansion of self, family heritage, adult status and social identity, development of self, and family maintenance. We discuss potential applications of the measure in research and practice.  相似文献

In general, systemic imbalance in pay between men and women is well established, but the literature on pay imbalance is mixed for nonprofit executives. Difference in organizational size could be a relevant factor in explaining pay imbalance, as previous research suggests average female nonprofit executives lead smaller organizations. The present study examines the role of governance accreditation on the gender gap in chief executive pay, using a 2 × 2 analysis of covariance to control for organizational size (as measured by annual revenue) when comparing samples of accredited and nonaccredited organizations in South Florida. We found a wage gap for gender, with female executives averaging 12% less compensation than male executives, after controlling for organizational size. No significant effect was found for accreditation; although the only significant difference between genders was in the nonaccredited sample, the findings hint that any trend towards pay equity would be due to a pattern of the male executives in the accredited sample being paid less than their counterparts in nonaccredited organizations.  相似文献

While many previous studies have identified a positive relationship between teachers unions and student achievement on standardized tests, little research to date has explored the channels through which unions might actually affect achievement. Utilizing multilevel random intercept models, we examine the effects of two categories of items commonly negotiated in teacher contracts—“industrial union” items and “professional union” items—on individual student math scores. Further, we assess the ability of these two clusters of variables to explain the positive union effect found in previous research. The results confirm that teachers unions are positively associated with student achievement and suggest that the industrial model explains moderately more of the union effect than the professional model; however, only the combination of both models is capable of reducing the union effect to nonsignificance. These findings are also confirmed in a supplemental analysis utilizing instrumental variables to account for the possibility of endogeneity. Finally, a decomposition of the union effect suggests that teachers unions are most beneficial to middle‐ and high‐achieving students. We conclude that through industrial and professional bargaining, teachers are able to secure higher salaries, credentialing, and greater autonomy which lead to improved student achievement.  相似文献

Many college students are using substances at levels consistent with Substance Abuse or Dependence, yet little explanation for this phenomenon exits. The aim of this study was to explore a risk factor profile that best separates those with low and high potential for having a substance use disorder (SUD). A discriminant function analysis revealed that participants with a high probability of having a SUD misperceive others' alcohol and marijuana use to a greater extent than those with a low probability of having a SUD. Implications for educators and counselors on college campuses are discussed.  相似文献

In this article, we argue for cognitive sociology as a framework for studying the sociology of race. Cognitive sociology concerns itself with classification, identity construction, meaning and collective memory and is thus centrally concerned with generic issues that apply well to racial category construction and maintenance. We, first, outline the cognitive sociology framework. We then elaborate on traditions in the sociology of race and racism that have implicit affinities to cognitive sociology. We argue that cognitive sociology provides a useful generic framework with which to look at specific issues in racial classification, the social construction of race, and to racist cognitions, while critical race theory and other sociology of race frameworks can compliment cognitive sociology by addressing issues of power and domination in cognitive frameworks.  相似文献

Concerns about potentially misleading reporting of pharmaceutical industry research have surfaced many times. The potential for duality (and thereby conflict) of interest is only too clear when you consider the sums of money required for the discovery, development and commercialization of new medicines. As the ability of major, mid-size and small pharmaceutical companies to innovate has waned, as evidenced by the seemingly relentless decline in the numbers of new medicines approved by Food and Drug Administration and European Medicines Agency year-on-year, not only has the cost per new approved medicine risen: so too has the public and media concern about the extent to which the pharmaceutical industry is open and honest about the efficacy, safety and quality of the drugs we manufacture and sell. In 2005 an Editorial in Journal of the American Medical Association made clear that, so great was their concern about misleading reporting of industry-sponsored studies, henceforth no article would be published that was not also guaranteed by independent statistical analysis. We examine the precursors to this Editorial, as well as its immediate and lasting effects for statisticians, for the manner in which statistical analysis is carried out, and for the industry more generally.  相似文献

Due to growing work-family demands, supervisors need to effectively exhibit family supportive supervisor behaviors (FSSB). Drawing on social support theory and using data from two samples of lower wage workers, the authors develop and validate a measure of FSSB, defined as behaviors exhibited by supervisors that are supportive of families. FSSB is conceptualized as a multidimensional superordinate construct with four subordinate dimensions: emotional support, instrumental support, role modeling behaviors, and creative work-family management. Results from multilevel confirmatory factor analyses and multilevel regression analyses provide evidence of construct, criterion-related, and incremental validity. The authors found FSSB to be significantly related to work-family conflict, work-family positive spillover, job satisfaction, and turnover intentions over and above measures of general supervisor support.  相似文献

Approximately 5% of older adults have a dementia diagnosis, and language deterioration is commonly associated with this disorder (Kempler, 2005). Several instruments have been developed to diagnose dementia and assess language capabilities of elderly adults. However, none of these instruments take a functional approach to language assessment as described by Skinner (1957). The purpose of this study was to develop and evaluate a function-based assessment for language deficits of older adults. Thirty-one participants were categorized into a control group (n  =  15) and a dementia group (n  =  16) based on their score on the Dementia Rating Scale-2. Individuals with dementia performed significantly worse on the tact assessment than those without dementia. Participants from both groups performed better on measures of tacts than intraverbals or mands, even though topographically identical responses were required in these assessments. The data provide support for Skinner''s conceptualization of functionally independent verbal operants.  相似文献
