Health and Medical Services Use: A Matched Case Comparison Between CCRC Residents and National Health and Retirement Study Samples

Little is known about the health status of adults living in continuing care retirement communities (CCRC). Using matched-case control, 458 adults from the Health and Retirement Study (HRS) or a CCRC-based sample were compared on total comorbidity, self-rated health, home health services use, and hospitalizations. At year 2, the CCRC sample reported more comorbidities (96%) but significantly better self-rated health (96% good/excellent) than the HRS sample (93% comorbidity, 73% good/excellent; p < .01). There were no significant differences in frequency of home health use or hospitalization. Living in a CCRC appears to be associated with higher self-ratings of health in this sample.     

The Ending of Menstruation: Perspectives and Experiences of Lesbian and Heterosexual Women

This article aims to theorize how a sample of menopausal women, lesbian and heterosexual, construct the ending of their periods, and what the experience means for them. Findings indicate that for most of the lesbian participants (who were in a sizeable minority), emotions of loss at the ending of periods were simultaneously expressed alongside positive feelings, and they engaged in greater introspection around the issue than did heterosexual women. However, lesbians did not all take up a singular subject position in relation to menstruation, indicating that there is fragmentation and plurality in how the body is experienced across a group.     

What Do We Mean by Performativity in Organizational and Management Theory? The Uses and Abuses of Performativity

John Austin introduced the formulation ‘performative utterance’ in his 1962 book How to Do Things with Words. This term and the related concept of performativity have subsequently been interpreted in numerous ways by social scientists and philosophers such as Lyotard, Butler, Callon and Barad, leading to the coexistence of several foundational perspectives on performativity. This paper reviews and evaluates critically how organization and management theory (OMT) scholars have used these perspectives, and how the power of performativity has, or has not, stimulated new theory‐building. In performing a historical and critical review of performativity in OMT, the authors’ analysis reveals the uses, abuses and under‐uses of the concept by OMT scholars. It also reveals the lack of both organizational conceptualizations of performativity and analysis of how performativity is organized. Ultimately, the authors’ aim is to provoke a ‘performative turn’ in OMT by unleashing the power of the performativity concept to generate new and stronger organizational theories.     

Chinese workers' work ethic in reformed state-owned enterprises: implications for HRD

Work ethic, as the construct of work-related values and attitudes, directly affects employees' job performance. Work ethic subjects to the influence of business and social practices. China is in the mix of major economical and political transformation, although little is known about how work ethic has changed for Chinese workers since the economic reform first initiated in 1979. This study is designed to examine work ethic currently held by workers of Chinese state-owned enterprises (SOEs). Findings revealed work ethic perceptions based on the multidimensional work ethic profile (MWEP), a Western work ethic profile, and the Confucian work ethic (CWE), an Eastern work ethic profile, resulted in similarities but often lived different life styles. The major differences tended to focus on perceptions of hard work, self-reliance and centrality of work. Other areas such as education, use of time, delay of graduation and other MWEP concepts were very similar to Chinese workers' work perceptions.     

The international nature of HRD scholarship

In the UK, human resource practitioners and academics alike are becoming more aware of the emergence of managing diversity. But what does managing diversity actually mean, how does it translate into practice, and what does it matter? The following paper briefly debates the rhetoric of managing diversity and considers whether managing diversity is a distinct approach to managing people or a means of diluting equal opportunities in UK organizations. With respect to the realities of the concepts in UK organizations, empirical data from a survey of sixty UK human resource professionals and general line managers is presented. We pose a number of cautionary questions, including what does it matter and to whom? By doing so we intend to encourage further critique and challenges in respect to the concept of managing diversity in organizations.     

Evaluation of the benchmark dose for point of departure determination for a variety of chemical classes in applied regulatory settings

Repeated-dose studies received by the New Substances Assessment and Control Bureau (NSACB) of Health Canada are used to provide hazard information toward risk calculation. These studies provide a point of departure (POD), traditionally the NOAEL or LOAEL, which is used to extrapolate the quantity of substance above which adverse effects can be expected in humans. This project explored the use of benchmark dose (BMD) modeling as an alternative to this approach for studies with few dose groups. Continuous data from oral repeated-dose studies for chemicals previously assessed by NSACB were reanalyzed using U.S. EPA benchmark dose software (BMDS) to determine the BMD and BMD 95% lower confidence limit (BMDL(05) ) for each endpoint critical to NOAEL or LOAEL determination for each chemical. Endpoint-specific benchmark dose-response levels , indicative of adversity, were consistently applied. An overall BMD and BMDL(05) were calculated for each chemical using the geometric mean. The POD obtained from benchmark analysis was then compared with the traditional toxicity thresholds originally used for risk assessment. The BMD and BMDL(05) generally were higher than the NOAEL, but lower than the LOAEL. BMDL(05) was generally constant at 57% of the BMD. Benchmark provided a clear advantage in health risk assessment when a LOAEL was the only POD identified, or when dose groups were widely distributed. Although the benchmark method cannot always be applied, in the selected studies with few dose groups it provided a more accurate estimate of the real no-adverse-effect level of a substance.     

Variations in age-specific homicide death rates: a cohort explanation for charges in the age distribution of homicide deaths

An age-period-cohort characteristic model previously used to explain age-period-specific rates of homicide arrests for those 15 to 49 from 1960 to 1995 is applied to measures of age-period-specific homicide deaths. The extension of this model to the examination of homicide victimization is significant because we are able to test the utility of the model across a longer time span (1930 to 1995) and a wider range of ages (10 to 79) and disaggregated by sex and race (Whites and non-Whites). Although the results indicate that past and recent shifts in age-period-specific rates of homicide deaths are associated with specific characteristics of cohorts, there are some important differences across race and sex groupings in the effects of these characteristics. The effects of the cohort variables examined in our model are independent of age and period, often substantively large, and last throughout the life course. The results are consistent with Durkheimian explanations of lethal violence, hypotheses from victimization theory, and basic tenets of cohort theory.     

The interaction of pillars in multi‐pillar pension systems: A comparison of Canada,Denmark, Netherlands and Sweden

Canada, Denmark, the Netherlands and Sweden have advanced multi‐pillar pension systems. Using micro‐simulations, this article presents a close examination of the interaction of pillars in these countries. The relative importance and the role of the different pension pillars vary from country to country, and according to age, income, gender and socio‐economic dimensions as well as between generations. A further area of investigation is the mitigation capacity of the four pension systems. On the one hand, adverse labour careers lead to lower life‐time earnings and lower private pension accruals. On the other hand, these effects are mitigated through the design of pillars and their interaction. Mitigation is important to income security and stability in retirement and to post‐retirement income distribution. However, mitigation mechanisms come at the cost of incentives. Moreover, in many countries, the generosity of public benefits is set to decrease – increasing the importance of private pensions. This will shift risk and uncertainty from employers and pension institutions to individuals. Thus, risks and uncertainties related to private pensions will become more important, raising questions about the division of responsibilities between public and private pensions, and about the potential of mitigating such risk through pillar interaction. These concerns are further reinforced by labour market changes. Although a pension system free of distortions is inconceivable, this article seeks to contribute to addressing how mitigation should be designed, and how mitigation and risk sharing should be balanced against incentives, challenges which are as much political as technical.     

Accurate Confidence Interval Estimation of Small Area Parameters Under the Fay–Herriot Model

Small area estimation has long been a popular and important research topic due to its growing demand in public and private sectors. We consider here the basic area level model, popularly known as the Fay–Herriot model. Although much of current research is predominantly focused on second order unbiased estimation of mean squared prediction errors, we concentrate on developing confidence intervals (CIs) for the small area means that are second order correct. The corrected CI can be readily implemented, because it only requires quantities that are already estimated as part of the mean squared error estimation. We extend the approach to a CI for the difference of two small area means. The findings are illustrated with a simulation study.
