Exercise self-regulation among older women participating in a heart disease-management intervention

Using behavioral self-regulation processes may facilitate exercise among older women with heart disease. Data from women in a heart disease-management program (n = 658, mean 73 years), was used to explore associations among exercise self-regulation components (i.e., choosing to improve exercise and observing, judging, and reacting to one's behavior) and exercise capacity. General linear models showed that choosing exercise predicted higher exercise self-regulation scores postprogram and 8 months later. In turn, these scores predicted greater improvements in exercise capacity concurrently and 8 months later. Interaction analyses revealed that the effect of self-regulation on exercise capacity was stronger among women who chose to work on exercise.     

THEORIES OF RISK: TESTING INVESTOR BEHAVIOR ON THE TAIWAN STOCK AND STOCK INDEX FUTURES MARKETS

This article considers four utility functions—concave, convex, S‐shaped, and reverse S‐shaped—to analyze the behavior of different types of investors on the Taiwan stock index and its corresponding index futures. Using stochastic dominance (SD) rules, we show that the existence of all four investor types is plausible. Risk averters prefer spot to futures, whereas risk seekers prefer futures to spot. Investors with S‐shaped utility functions prefer spot (futures) to futures (spot) when markets move upward (downward). Investors with reverse S‐shaped utility functions prefer futures (spot) to spot (futures) when markets move upward (downward). We show that both spot and futures markets can exist when only risk averters are present, but futures can dominate spot only if there is some risk‐seeking behavior. These results are robust with respect to subperiods, spot returns including dividends, and diversification. (JEL C14, G12, G15)     

Public Perceptions About Sex Offenders and Community Protection Policies

Sex offenders and sex crimes provoke a great deal of anxiety in our society, and over the past decade, lawmakers have passed a variety of social policies designed to protect the public from sexual victimization. The purpose of this study was to examine public perceptions about sex offenders and community protection policies. Data were obtained from a sample of 193 residents in Melbourne, Florida. It was hypothesized that the public holds some inaccurate beliefs about sex offenders, and that there is strong public support for community protection policies. It was found that community members believe that sex offenders have very high recidivism rates, view sex offenders as a homogeneous group with regard to risk, and are skeptical about the benefits of sex offender treatment. The hypothesis that public perceptions contradict empirical research was supported. Community members were overwhelmingly in favor of public disclosure of information about registered sex offenders, although they did not express as much support for residence restrictions. Implications for public policy, and for the media's role in shaping public perceptions, are discussed.     

Life values,family support and psychosocial adaptation among older people in Taiwan: an institutional and community comparison

The purpose of this study was to investigate the psychosocial adaptation among elderly persons in institutional and community settings, and to explore factors influencing their adaptation. A cross-sectional survey was conducted with a convenience sample of 165 residents of four institutions (two assisted-living facilities and two nursing homes) and 209 community-dwelling elders served by a primary care centre, all located in middle Taiwan. A structured interview questionnaire was used to collect data. Results: community-dwelling elderly had significantly higher adaptation scores than those in institutional settings. Factors related to adaptation differed between institutional and community settings, with more variables influencing adaptation in the community than in the institution. Physical functional status was the major influence on adaptation of the elderly in institutions. Dietary support from family was negatively associated with adaptation in this group. Influencing factors for community-dwelling elders were more complicated, including perceived family emotional and economic support, personal life values and physical functional status. Implications: greater support from government, including economic resources and assistance in community care are needed to achieve the policy goal of ‘aging in place’. Further investigation of the influence of family interaction on elders' adaptation is needed.     

Does Privatization Protect Natural Resources? Property Rights and Forests in Guatemala

Objectives . Property rights are central to debates about natural resource policy. Governments traditionally have been seen as the appropriate custodians of natural resources for their citizens. More recently, many argue the privatization of property rights will ensure that users have incentives to manage their resources well. Common property, to the extent it is discussed at all, is seen as leading to the tragedy of the commons. We evaluate these claims by assessing property rights and forest conditions in two private and three communal forests in Guatemala. Methods . Data on biological and social phenomena from five forests (151 plots) and their associated communities were collected using the International Forestry Resources and Institutions Research Program protocols. Ordinary least squares regression was used to analyze four models. We examined t -scores for differences in coefficients for the different models. Results . The models demonstrate that de jure property rights are not a powerful predictor of variations among the sampled forests. Conclusions . We argue that de facto institutions and their enforcement are much more important than de jure property rights to forest management. Communities holding a forest in common can, under certain circumstances, create institutions to manage their resources as successfully as—or more successfully than—private owners.     

The Role of Curiosity in the Sociopolitical Development of Black and Latinx Adolescents

Sociopolitical development, the process of coming to understand and take action against systems of oppression, is associated with key outcomes for youth. Although rooted in Paulo Freire's work on critical consciousness, sociopolitical development models overlook a motivational attribute—curiosity—that Freire characterized as a catalyst of such development. This longitudinal study investigated the relationship between curiosity and two aspects of sociopolitical development (social analysis, societal involvement) in a sample of Black and Latinx adolescents (N = 659). Longitudinal growth models demonstrated positive growth in all constructs over 4‐years of high school. Multivariate growth models revealed a positive correlation at baseline between curiosity and both constructs; growth in curiosity was also positively correlated with growth in social analysis and societal involvement.     

Using Frontier Analysis to Evaluate Company Performance

The measurement of performance is critical to nearly all managerial disciplines. Yet little is known about the aggregation characteristics of the components of performance and how our notion of a ‘good performing firm’ relates to what we use as a dependent variable. In this paper we propose an approach to the measurement of performance that uses the logic of frontier analysis and the technique of data envelopment analysis. The approach is shown to be a reasonable representation of the multidimensional nature of performance and is shown to replicate, effectively, the components that strategic management scholars typically consider when discussing performance. It is also shown to be superior to the simpler alternatives based on traditional approaches to performance measurement.
