In this paper, we analyze the ethical issues of using honesty and integrity tests in employment screening. Our focus will be on the United States context: legal requirements related to applicant privacy differ in other countries, but we posit that our proposed balancing test is broadly applicable. We start by discussing why companies have ethical and legal obligations, based on a stakeholder analysis, to assess the integrity of potential employees. We then move to a consideration of how companies currently use background checks as a pre‐employment screening tool, noting their limitations. We then take up honesty and integrity testing, focusing particularly on the problems of false positives and due process. We offer a balancing test for the use of honesty and integrity testing that takes in three factors: (1) the potential harm posed by a dishonest employee in a particular job, (2) the linkage between the test and the assessment process, and (3) the accuracy and validity of the honesty and integrity test. We conclude with implications for practice and future research.  相似文献

Invasive species risk maps provide broad guidance on where to allocate resources for pest monitoring and regulation, but they often present individual risk components (such as climatic suitability, host abundance, or introduction potential) as independent entities. These independent risk components are integrated using various multicriteria analysis techniques that typically require prior knowledge of the risk components’ importance. Such information is often nonexistent for many invasive pests. This study proposes a new approach for building integrated risk maps using the principle of a multiattribute efficient frontier and analyzing the partial order of elements of a risk map as distributed in multidimensional criteria space. The integrated risks are estimated as subsequent multiattribute frontiers in dimensions of individual risk criteria. We demonstrate the approach with the example of Agrilus biguttatus Fabricius, a high‐risk pest that may threaten North American oak forests in the near future. Drawing on U.S. and Canadian data, we compare the performance of the multiattribute ranking against a multicriteria linear weighted averaging technique in the presence of uncertainties, using the concept of robustness from info‐gap decision theory. The results show major geographic hotspots where the consideration of tradeoffs between multiple risk components changes integrated risk rankings. Both methods delineate similar geographical regions of high and low risks. Overall, aggregation based on a delineation of multiattribute efficient frontiers can be a useful tool to prioritize risks for anticipated invasive pests, which usually have an extremely poor prior knowledge base.  相似文献

Despite renewed interest in traditional trait approaches to leadership and despite recent demographic trends towards an aging workforce, research on leaders' age as a specific demographic trait variable has remained surprisingly sparse and fragmented. This article provides a comprehensive review of the empirical literature on this issue. Although a body of research relating leaders' age with their behaviors and outcomes has emerged, the existing findings exhibit little consistency and lack theoretical coherence. Integrating theories of emotional aging with research on emotions and leadership, we therefore develop a novel, emotion-based framework that explicates key mechanisms and boundary conditions underlying age–leadership linkages. Moreover, we outline opportunities for further theoretical extensions and provide recommendations for future empirical work. Overall, this article paves new ground for contemporary research on leadership traits by highlighting the relevance of leaders' age, summarizing current knowledge on this issue, and providing new theoretical and empirical directions.  相似文献

Data from a heterogeneous‐agents economy with incomplete asset markets and indivisible labor supply are simulated under various fiscal policy regimes and an approximating representative‐agent model is estimated. Preference and technology parameter estimates of the representative‐agent model are not invariant to policy changes and the bias in the representative‐agent model’s policy predictions is large compared to predictive intervals that reflect parameter uncertainty. Since it is not always feasible to account for heterogeneity explicitly, it is important to recognize the possibility that the parameters of a highly aggregated model may not be invariant with respect to policy changes.  相似文献

As the transition to adulthood becomes more protracted and less orderly, fewer young people occupy adult roles and experience the social control associated with these roles. One might therefore expect behaviors associated with the teenage years to spill over into older age groups, reflecting postponed entrance into full social adulthood. We test this hypothesis by examining trends over time in the age distribution of crime, substance use, and violent death. We find little evidence that behaviors typical of adolescence are moving upward to older ages. Although the achievement of adult roles is being pushed to older ages, this stretching of the transition to adulthood is not reflected in the observed patterns of substance use, violent death, and arrests.  相似文献

Objective. Taking an institutional approach to the determinants of outcomes for women in science and engineering, we examine the effects on women's percentages among undergraduate majors and among degree recipients of four basic factors: (1) the percentage of faculty who are women in the students' major science/engineering area; (2) the students' disciplines (biology, physical sciences, and engineering); (3) the type of institution in which students are enrolled (“Research I” vs. others); and (4) a time trend (1984–2000). Method. We use longitudinal, multivariate, and multi‐institutional data from the Integrated Postsecondary Data System (IPEDS) and from a mail survey of registrars. Results. Over the observation period, the women's percentages have risen steadily. The effects of disciplines and departments are stronger than those of institutions. Especially notable is that the percentages of women among undergraduate science/engineering majors and degree recipients are associated with the percentages of women among the faculty in these fields. Conclusion. The findings contribute empirically to the discussion about the effects of “role models” for the participation and performance of women in science and engineering—and point to the strong effects of departments, compared to institutions, in accounting for degrees awarded to undergraduate women.  相似文献

The ongoing HIV/AIDS pandemic in southern Africa continues to manifest itself in unexpected ways. While the consequences of the disease appear straightforward in some aspects—e.g., medical, labor, cost—in other respects the repercussions, while large, are nonetheless highly nuanced and can be counterintuitive. This paper reports on the intersection of HIV/AIDS, migration, livelihood adaptation, land tenure, and forest conservation, to outline how adaptation to the pandemic has reworked significant aspects of land tenure to result in increased forest conservation in southern Zambia in the near to medium-term. The research uses a combination of ethnography, case studies, household survey and spatial analyses and finds that HIV/AIDS is used in customary legal settings to enhance land access. We also draw links to practical and theoretical implications of the relationship between HIV/AIDS, land tenure, and deforestation in Sub-Saharan Africa.  相似文献

Au cows du XXe siècle, la différence de l'espérance de vie entre les sexes dans les pays industrialisés a augmenté en faveur des femmes. On a remarqué récemment un renversement du modèle a long terme de cet écart dans certains pays. Au Canada, entre 1981 et 2000, cette différence a diminué d'environ deux ans. Une grande partie de ce phénomène sexplique par un taux de mortalité moins élevé chez les hommes que celui auquel on se serait attendu par rapport aux cardiopathies, aux cancers du poumon, aux accidents et à la violence (les suicides non compris). Le changement de la préevalence du tabagisme chez les hommes et chez les femmes est en forte corrélation avec la modification de la mortalité due aux maladies du c?ur et au cancer en fonction des sexes. Les raisons qui expliquent la diminution de la mortalité chez les hommes par suite d'accidents et de violence sont cependant moins claires et exigent des recherches plus approfondies. Over the 20th century sex differences in life expectancy in the industrialized countries have widened in favour of women. Recently, a reversal in the long‐term pattern of this differential has been noted in some countries. In Canada, between 1981 and 2000, this differential narrowed by almost two years. Greater than expected improvements in male death rates with respect to heart disease, lung cancer, accidents and violence (excluding suicide) explain a large part of this phenomenon. Change in male and female smoking prevalence correlates strongly with change in sex differences in mortality from heart disease and cancer. The reasons underlying men's greater mortality improvements in regard to accidents and violence are less clear and need further investigation.  相似文献
