 This paper examines the problem of distilling conflicting interpersonal comparisons into a single set of interpersonal comparisons. The mapping that achieves this has a richer co-domain than all social choice problems (and a richer domain than most social choice problems). The set of mappings satisfying a mild set of restrictions is very small. If interpersonal comparisons embody ratio-scale comparability then the mapping is Cobb–Douglas in form; if interpersonal comparisons embody no more than level and difference comparability then the mapping must be dictatorial and it is impossible to combine different interpersonal comparisons.

This article discusses the challenges and opportunities encountered in interviewing organizational elites. Drawing on a wide range of experiences in elite interviewing, I offer suggestions for gaining access to elites, controlling the interview, obtaining the highest-quality interview data, and writing effectively about those data. I also discuss the 'dilemma of seduction' that can occur in elite interviewing and suggests ways to both present and critique the worldview of elites when writing about qualitative interviews.  相似文献

Accumulating research suggests that the adoption of high performance work practices (HPWPs) is related to organizations' performance. The evidence base is limited by its reliance on retrospective survey reports. This study uses an intervention, including longitudinal interview and survey reports, of the implementation and outcomes of the introduction of HPWPs alongside time series data of objective performance metrics recorded before and after the intervention. The results showed that the implementation of HPWPs was associated with subsequent and sustained increases in productivity and safety performance. The study suggests that a specifically designed intervention involving HPWPs can have beneficial effects both on productivity and safety, but other intermediary variables associated with the implementation process may be critical in mitigating potentially detrimental worker welfare effects arising from work intensification.  相似文献

Traditional additivity models provide little flexibility in modeling the dose–response relationships of the single agents in a mixture. While the flexible single chemical required (FSCR) methods allow greater flexibility, its implicit nature is an obstacle in the formation of the parameter covariance matrix, which forms the basis for many statistical optimality design criteria. The goal of this effort is to develop a method for constructing the parameter covariance matrix for the FSCR models, so that (local) alphabetic optimality criteria can be applied. Data from Crofton et al. are provided as motivation; in an experiment designed to determine the effect of 18 polyhalogenated aromatic hydrocarbons on serum total thyroxine (T4), the interaction among the chemicals was statistically significant. Gennings et al. fit the FSCR interaction threshold model to the data. The resulting estimate of the interaction threshold was positive and within the observed dose region, providing evidence of a dose‐dependent interaction. However, the corresponding likelihood‐ratio‐based confidence interval was wide and included zero. In order to more precisely estimate the location of the interaction threshold, supplemental data are required. Using the available data as the first stage, the Ds‐optimal second‐stage design criterion was applied to minimize the variance of the hypothesized interaction threshold. Practical concerns associated with the resulting design are discussed and addressed using the penalized optimality criterion. Results demonstrate that the penalized Ds‐optimal second‐stage design can be used to more precisely define the interaction threshold while maintaining the characteristics deemed important in practice.  相似文献

Sick Building Syndrome (SBS) involves seemingly healthy individuals experiencing long-lasting symptoms of physical distress in their work settings and is estimated to exist in 20 to 30% of all work settings in the USA. We examined differences in stress, social support and both physical and psychological symptoms reported by hospital personnel working in known SBS sites in Halifax, Nova Scotia (n = 297) with control employees working in relatively SBS-free settings (n = 228). We found that employees reporting that their health had been affected by the building in which they worked and those complaining of poor air quality were more likely to be found in SBS locations. In addition, those people with higher levels of organizational support and marginally higher levels of union support were also more likely to be found in SBS locations. Further analyses revealed that employees with higher role overload and greater family support, but lower levels of organizational support were more likely to report that their own health had been adversely affected by their place of work. Perceptions of poor air quality were predicted by higher levels of role conflict, role overload, and organizational stress and lower levels of organizational support. These results suggest that SBS may not be solely dependent on environmental factors.  相似文献

Parents' child–rearing behaviors have been identified as major sources of influence on the self–esteem of adolescents from Western societies and Chinese adolescents in Hong Kong. The pattern of relationships found in samples of Hong Kong adolescents has been similar to the pattern found among samples of U.S. adolescents, but contrary to what might be expected in collectivistic societies such as mainland China. The purpose of this study, therefore, was to test specific dimensions of parenting behaviors as possible predictors of adolescents' self–esteem in mainland China. Self–report data were acquired for this study from 480 adolescents who attended secondary schools located in Beijing. Results indicated that patterns of socialization between parents and adolescents in mainland China were similar to those found in the United States, although explanations for these results may differ from those characteristic of the United States and other Western societies. Reasoning, monitoring, and autonomy–granting behavior by Chinese parents were positive predictors, whereas punitiveness was a negative predictor of Chinese adolescents' self–esteem (both males and females). Contrasting with patterns commonly found in the United States was the finding that parental support was not a predictor of Chinese adolescents' self–esteem.  相似文献

We examine the relationship between union presence and CEO compensation. Based on the notion that the union taxes the firm's returns, we test whether unions successfully capture a larger share of the firm's returns with respect to the share captured by the CEO. On average CEOs in union firms are paid 19 percent less than those in nonunion firms, after controlling for several determinants of CEO pay. CEO compensation risk is lower in union firms because the reduced compensation risk is a trade-off for the lower level of CEO compensation.  相似文献

Complementing previous literature on welfare reform and the character of jobs in the low-wage labour market, we illustrate the lack of regularity and security that mark the jobs held by many low-income mothers. To do so, we present a typology of mothers’ work patterns and illustrate their experiences through case examples. Our qualitative analysis of longitudinal pathways-to-work in three cities involved an examination of the experiences of 99 diverse, low-income working mothers with a young child. The work patterns that emerged from this analysis include: continuous duration of a single job; multiple job spells; underemployment; and churning in and out of employment. Findings indicate that a complicated ‘coming together’ of well-paying stable jobs, consistent aid from public systems and stable family networks are necessary for mothers to take even the first steps into stable employment.  相似文献

The multi‐agency, multiple intervention Promoting Prevention initiative to prevent youth offending in Swansea was evaluated with a computer‐based interactive questionnaire with 580 young people (aged 11–18). Results indicate that multiple exposure to risk factors within the main domains of the young person's life (for example, family, school) significantly increases the likelihood that a young person will become involved in problem behaviours. In contrast, exposure to multiple protective factors decreases the likelihood of these behaviours. Evaluation indicates that Promoting Prevention's consultative methodology is an empowering and engaging way of targeting interventions to promote positive behaviours and prevent anti‐social behaviour in young people.  相似文献
