We reviewed the Journal of Applied Behavior Analysis (JABA), Journal of Organizational Behavior Management (JOBM), and Behavior Analysis in Practice (BAP) from 1990 to 2016, to identify articles that evaluated organizational behavior management interventions in a human service setting. Of those articles, 75 articles met the inclusion criteria for the review, 44 from JABA (1990 to 2016), 22 from JOBM (1990 to 2016), and 7 from BAP (2008 to 2016). We categorized each selected article by setting, employee population, client population, assessment, dependent variable, independent variable, and outcome measures. Results from the review are discussed for all three journals. Recommendations are made to broaden the scope of population and dependent variable targets, include more assessments, and include outcome data when applicable.  相似文献

A Bayesian approach, implemented using Markov Chain Monte Carlo (MCMC) analysis, was applied with a physiologically‐based pharmacokinetic (PBPK) model of methylmercury (MeHg) to evaluate the variability of MeHg exposure in women of childbearing age in the U.S. population. The analysis made use of the newly available National Health and Nutrition Survey (NHANES) blood and hair mercury concentration data for women of age 16–49 years (sample size, 1,582). Bayesian analysis was performed to estimate the population variability in MeHg exposure (daily ingestion rate) implied by the variation in blood and hair concentrations of mercury in the NHANES database. The measured variability in the NHANES blood and hair data represents the result of a process that includes interindividual variation in exposure to MeHg and interindividual variation in the pharmacokinetics (distribution, clearance) of MeHg. The PBPK model includes a number of pharmacokinetic parameters (e.g., tissue volumes, partition coefficients, rate constants for metabolism and elimination) that can vary from individual to individual within the subpopulation of interest. Using MCMC analysis, it was possible to combine prior distributions of the PBPK model parameters with the NHANES blood and hair data, as well as with kinetic data from controlled human exposures to MeHg, to derive posterior distributions that refine the estimates of both the population exposure distribution and the pharmacokinetic parameters. In general, based on the populations surveyed by NHANES, the results of the MCMC analysis indicate that a small fraction, less than 1%, of the U.S. population of women of childbearing age may have mercury exposures greater than the EPA RfD for MeHg of 0.1 μg/kgg/day, and that there are few, if any, exposures greater than the ATSDR MRL of 0.3 μgg/kgg/day. The analysis also indicates that typical exposures may be greater than previously estimated from food consumption surveys, but that the variability in exposure within the population of U.S. women of childbearing age may be less than previously assumed.  相似文献

In recent years, the political nature of nonprofit funding has been well established, with research focusing on increased demands for accountability (Eikenberry and Kluver, 2004), difficulties in selecting accountability measures (Reed, Jones, and Irvine, 2005), and the shift from organizational mission that can occur while trying to adhere to funding requirements (Adcroft and Willis, 2005; Parsons and Broadbridge, 2004). This article examines the dynamics between a funder and the nonprofit organizations it funds within an evolving accountability process. Specifically, we use qualitative methods to examine the negotiations between the funder and the nonprofits. Both sides in the funding relationship face tensions as they attempt to work within the constraints of this specific funding regime while trying to maintain their focus on social justice outcomes.  相似文献

We explore how marital aspirations are related to the sexual behaviors of adolescents and young adults in Malawi, where HIV/AIDS prevalence among adults exceeds 10%. We also consider whether the specter of AIDS is shaping ideals about marriage. By combining survey data (N = 1,087) and in‐depth interviews (N = 133) with young Malawians from the Malawi Diffusion and Ideational Change Project, we show that looking for and finding a suitable spouse are linked to sexual behaviors and, thus, HIV risks. Moreover, concerns about contracting HIV are closely tied to the ideal characteristics of a future spouse. Our findings draw long‐overdue attention to the importance of marital aspirations in understanding adolescent sexual behaviors and risks in the era of AIDS.  相似文献

This article discusses a longitudinal study of firms selected for their expertise in environmental analysis. It is primarily designed to test two general propositions. The first, that environmental analysis is increasing in importance over time— both within and between firms; and the second, that environmental analysis is most viable as a separate, freestanding function within the organization.  相似文献

A period of more rigorous strategic management is under way in consumer service businesses. In banking, insurance, lodging, media, retailing, housing, restaurants and education, more growth must come from competitive share shift. This paper b shows the need for a different set of strategies to win in services than have been shaped in the product business context. Specific illustrations show how leading U.S. consumer service companies are building strategic advantage while also improving the value of their business.  相似文献

The presence today of ‘thinking’ robots has great implications for general management (as opposed to production management). The possibility is clear that within a decade a supercomputer may share or usurp functions of a corporate chief executive—functions that up to now have been thought unsharable. Now is the time to begin planning for such a development.  相似文献

Son preference and sex composition of children: Evidence from india   总被引:1,自引:0,他引:1  
Clark S 《Demography》2000,37(1):95-108
Although the effect of son preference on sex composition of children ever born is undetectable in national-level estimates that aggregate across all families, this article provides empirical evidence from India that son preference has two pronounced and predictable family-level effects on the sex composition of children ever born. First, data from India show that smaller families have a significantly higher proportion of sons than larger families. Second, socially and economically disadvantaged couples and couples from the northern region of India not only want but also attain a higher proportion of sons, if the effects of family size are controlled.  相似文献

Laura Bragg, a member of the first graduating class at Simmons College, journeyed to Charleston as a New Woman in 1909. As the first woman director of a major scientific museum in the United States, Bragg transformed the Charleston Museum into a public education institution and became an innovative leader in museum education. This article documents Bragg's contributions within the context of antebellum culture where the Southern Belle was placed on a Victorian pedestal and Boston marriages were an unknown phenomenon. Using extensive and hitherto unpublished correspondence, the authors detail Bragg's lesbian relationships and describe her network within the homosexual male community during the era of the Charleston Renaissance.  相似文献
