Sport participation and positive development in older persons

In many Western countries, more and more people are living longer. As part of this demographic shift, increasing numbers are participating in Masters sport. In the past, sport was considered important for the development of young people; however, the potential for sport participation to affect positive development across the lifespan is now recognized. The purpose of this paper is to introduce conceptual frameworks from developmental psychology that are being used to understand youths’ positive development through sport, and to explore these frameworks in the context of sport as an avenue for positive development in older persons. To achieve this aim, we outline research on sport participation as it applies to youth development and consider relevant aspects as they broadly apply to development later in life. This discussion highlights the inherent paradox of sport participation—that it has the potential to provide considerable positive growth but also the potential for significant negative consequences. Finally, we explore areas of future research related to positive development in older persons through sport.     

Initial Validation of the Open Adoption Scale: Measuring the Influence of Adoption Myths on Attitudes Toward Open Adoption

All adoptions, including those facilitated by public agencies, should be evaluated for openness. Although there are no national figures related to openness in public welfare, there are indications that it is not considered in all cases. Adoption myths may be one of the reasons that adoption workers do not always assess a family's ability to maintain a more open adoption arrangement. The following study is the initial validation of a multidimensional psychometric instrument developed to measure myths as they relate to open adoption. Based on a sample of 547 university students, the results indicate very good reliability and acceptable factorial and construct validity. The instrument was designed as a training and research tool to inform child welfare personnel and policy makers of the influence of adoption-related myths on child welfare adoption practice.     

NISO Webinar: “The Case of the Disappearing Journal: Solving the Title Transfer and Online Display Mystery” (November 10, 2010)

Abstract

In December 2012, Eric Hanson interviewed Christopher Cronin, director of technical services at the University of Chicago, about their participation as an RDA test partner and issues surrounding RDA training and implementation.     

Does a food for education program affect school outcomes? The Bangladesh case

The Food for Education (FFE) program was introduced to Bangladesh in 1993. This paper evaluates the effect of this program on school participation and duration of schooling using household survey data collected in 2000. Using propensity score matching combined with difference-in-differences methodologies, we find that the program is successful in that eligible children on average have 15% to 26% higher school participation rates, relative to their counterfactuals who would have been eligible for the program had they lived in the program-eligible areas. Conditional on school participation, participants also stay at school 0.7 to 1.05 years longer than their counterfactuals.     

Improving Cancer Dose–Response Characterization by Using Physiologically Based Pharmacokinetic Modeling: An Analysis of Pooled Data for Acrylonitrile-Induced Brain Tumors to Assess Cancer Potency in the Rat

Historically, U.S. regulators have derived cancer slope factors by using applied dose and tumor response data from a single key bioassay or by averaging the cancer slope factors of several key bioassays. Recent changes in U.S. Environmental Protection Agency (EPA) guidelines for cancer risk assessment have acknowledged the value of better use of mechanistic data and better dose–response characterization. However, agency guidelines may benefit from additional considerations presented in this paper. An exploratory study was conducted by using rat brain tumor data for acrylonitrile (AN) to investigate the use of physiologically based pharmacokinetic (PBPK) modeling along with pooling of dose–response data across routes of exposure as a means for improving carcinogen risk assessment methods. In this study, two contrasting assessments were conducted for AN-induced brain tumors in the rat on the basis of (1) the EPA's approach, the dose–response relationship was characterized by using administered dose/concentration for each of the key studies assessed individually; and (2) an analysis of the pooled data, the dose–response relationship was characterized by using PBPK-derived internal dose measures for a combined database of ten bioassays. The cancer potencies predicted for AN by the contrasting assessments are remarkably different (i.e., risk-specific doses differ by as much as two to four orders of magnitude), with the pooled data assessments yielding lower values. This result suggests that current carcinogen risk assessment practices overestimate AN cancer potency. This methodology should be equally applicable to other data-rich chemicals in identifying (1) a useful dose measure, (2) an appropriate dose–response model, (3) an acceptable point of departure, and (4) an appropriate method of extrapolation from the range of observation to the range of prediction when a chemical's mode of action remains uncertain.     

Hate Speech and Constitutional Protection: Priming Values of Equality and Freedom

Freedom of speech and equality are two basic values in American culture that cause a value conflict with regard to hate speech. This study examined the effects of priming of values of freedom of speech and equal protection (equality) on perceptions of and attitudes toward hate speech and value prioritization. Data were collected from 159 college students. Priming of freedom of speech directed participants' attitudes and values toward advocating freedom of speech, whereas priming for equal protection directed attitudes and values toward the harm of hate speech. Participants primed for free speech viewed hate speech (introduced via scenarios) as less harmful and the speaker as less accountable than those primed for the harm of hate speech and a control group.     

Managing Money in Marriage: Multilevel and Cross‐National Effects of the Breadwinner Role

We examine whether institutionalized practices and beliefs regarding breadwinning roles are associated with the choice of more or less equal money management strategies in marriage. Using cross‐national data from 21 country contexts in the International Social Survey Programme and multilevel modeling, we find that in contexts of shared breadwinning, there is a greater likelihood of shared management of money, controlling for the relative income contribution of each spouse. We also find some evidence that the effect of spouses’ relative income contributions diminishes in contexts of shared breadwinning. Our analysis comparing women’s and men’s money management is consistent with previous research indicating that women’s management may be more work than power.
