On the efficiency of using the sample kurtosis in selecting optimal lpestimators

This paper examines the efficiency of thesample kurtosisin obtaining L_P estimates as an estimates of central tendency for symmetric distributions. Moreover, guidelines are established for determining an optimal value of P based on the kurtosis of the error distribution.     

Measuring Christian Beliefs that Affect Managerial Decision-Making: A Beginning

Although considerable work has been done on the measurement of religious values and beliefs, little is understood about their effect on managerial values and decision making. This paper reports on theoretical work by the authors identifying Christian religious beliefs that might affect managerial decision making; it also reports the results of empirical work validating five scales of religious beliefs that might affect managerial decision making. Future research directions are proposed. This revised version was published online in August 2006 with corrections to the Cover Date.     

Union-Nonunion differentials and establishment size: Evidence from the NLSY

We provide new empirical evidence on union-nonunion differentials using the 1990 wave of the National Longitudinal Surveys of Youth (NLSY) data set which allows us to examine a broader set of fringe benefits than most other studies and provides a rich set of control variables. Our major finding is that the union effect decreases with establishment size for both components of the compensation structure, i.e., wages and fringe benefits. An earlier version of this paper was presented at the Southern Economic Association conference in Washington, DC in 1996. We thank Tom Hyclak and other session participants.

Defining delayed consequences as reinforcers: some do, some don't, and nothing changes

Results of a survey sent to members of the editorial boards of five behavior-analytic journals in 1990 indicated that there was no consensus among respondents with respect to whether delayed events can function as reinforcers (Schlinger, Blakely, Fillhard, & Poling, 1991). Since that time, several studies with nonhuman animals have demonstrated that events delayed by at least several seconds can increase the probability of occurrence of the responses that produce them. To determine the relative number of contemporary behavior analysts who nonetheless believe that reinforcers must immediately follow the responses that produce them, the present study replicated the procedures used by Schlinger et al., with similar results. That is, respondents did not agree with respect to whether delayed events could be reinforcers.     

Successful Aging And Creativity In Later Life

This study examined the meanings older people attached to successful aging and its relationship to creative activity. Thirty-six contributors to a senior art exhibition participated in this study and ranged in age from 60–93. Interviews with participants explored their understandings of successful aging and creativity, the factors viewed as necessary for each, and the benefits of creative activity and its relationship to successful aging. Qualitative data were coded by two independent reviewers. Content analysis confirmed six features of successful aging: a sense of purpose, interactions with others, personal growth, self-acceptance, autonomy, and health. The findings indicate that creative activity contributes to successful aging by fostering a sense of competence, purpose, and growth. Artistic creativity also facilitates successful aging by encouraging the development of problem-solving skills, motivation, and perceptions that translate into a practical creativity in the way these individuals manage their everyday lives.     

Consumer discrimination in the NBA: An examination of the effect of race on the value of basketball trading cards

In this research we use sport trading cards to examine consumer discrimination in the NBA. Using a Tobit analysis, we test whether the race of a player affects the value (price) of his NBA trading card. We find that a player's race does not affect the value of NBA trading cards. We conclude that some forms of consumer discrimination are declining in the NBA.     

An Exploratory Analysis of Executive Functioning for Female Sexual Offenders: A Comparison of Characteristics Across Offense Typologies

This study examined the association between female sexual offending behavioral patterns, as delineated by Sandler and Freeman's (2007 Sandler, J. C. and Freeman, N. J. 2007. Typology of female sex offenders: A test of Vandiver and Kercher. Sex Abuse, 19: 73–89. [Crossref], [PubMed], [Web of Science ®] , [Google Scholar]) typologies, and executive functioning. The sample included all referrals for sexual offender assessments within a women's maximum/medium security prison between January 2009 and October 2009. Each subject was administered the Stroop (Golden & Freshwater, 2002 Golden, C. J. and Freshwater, S. M. 2002. The Stroop color and word test: A manual for clinical and experimental uses, Wood Dale, IL: Stoelting Company.  [Google Scholar]) and Trail Making Test (Reitan, 2004 Reitan, R. M. 2004. “Validity of the trail making test as an indicator of organic brain damage”. In Neuropsychological assessment, 4th, Edited by: Lezak, M. D., Howison, D. B. and Loring, D. W. 371–374. New York: Oxford University Press.  [Google Scholar]) and were assigned to a typological category. Nonparametric analyses were conducted to determine if there was an association between typology and performance on neuropsychological tests. Results yielded no significant associations between test scores and typological category. Subjects displayed average capacities for a subset of executive functions, suggesting that the mechanisms for sexually offending behavior in females may differ from males.     

Lesbian and gay men’s perceptions of their local area agency on aging

This article reviews data from a qualitative study of lesbians and gay men about engagement with their local Area Agency on Aging (AAA). Findings include lack of knowledge about the local AAA, feelings of exclusion, and the need for better outreach. It is important that AAAs engage their local lesbian, gay, bisexual, and transgender (LGBT) elders, as data show they are at higher risk for aging alone and can often harbor mistrust of formal services due to lifetimes of discrimination. Suggestions on where AAAs can find training and resources on reaching out to the LGBT older adult community and implications for the profession of social work are provided.
