Perceptional inequality and preferential judgements: An empirical examination of distributional axioms

There are two categories of income distribution evaluations: first, the more-or-less “value-free” perception of income inequality as a statistical dispersion; and second, the valuation of income distributions according to an explicit social welfare function which is meant to capture all of society's value judgements. These societal value judgements can be expressed in the form of preferences. Whereas the inequality perception of income distributions appeals to an observer's sober judgement, the revelation of preferences with respect to specific income distributions appeals to his or her sentiments. This paper is an empirical analysis which investigates the juxtaposition of preferences with respect to income distributions and corresponding perceptions of distributional inequality. We do this through a questionnaire in which attitudes towards various distributional axioms are tested. The source of our data is 1773 completed questionnaires collected from five German universities. Based on our data, we observe that individuals' preference orderings over the set of income distributionssubstantially deviate from their perceptions of distributional inequality. In fact, our test responses showed that even when some income distribution is judged to be more unequal than another, that distribution might be preferred, as it accords higher incomes to each individual. We hold that the preference for these greater incomes expresses a compensation for the increased degree of inequality. This explanation applies both to equiproportional and to equal fixed-sum increases in incomes, which implies a support of Paretian ethics.     

Negative affect and hormone levels in young adolescents: Concurrent and predictive perspectives

The purpose of this study was to test hypotheses regarding (1) relations among negative affect and hormones of gonadal and adrenal origin in young adolescents, at three times of measurement, over a one-year period; and (2) stability of negative affect. The sample consisted of 10- to 14-year-old boys (N=56) and 9- to 14-year-old girls (N=52). The adolescents were assessed three times at 6-month intervals over one year. Serum levels of gonadotropins, gonadal steroids, adrenal androgens, and cortisol were assessed, as well as stage of pubertal development (Tanner criteria). The negative affect assessments consisted of self-report questionnaire and interview measures of anxiety and depressive affect, as well as mother reports of internalizing behavior problems. In the concurrent (cross-sectional) analyses, boys reporting higher levels of negative affect tended to be those at higher genital stage or older age, with lower testosterone and cortisol levels and lower dehydroepian-drosterone sulphate levels. In the longitudinal analyses, negative affect, and to a lesser extent hormone levels at the first time of measurement predicted negative affect 12 months later. The findings suggest that puberty-related hormone levels should be considered along with psychological characteristics in examining the processes involved in the development of negative affect during the pubertal years.Received Ph.D. from The Pennsylvania State University.

The sporting life: Athletic activities during early adolescence

The decline in sports participation that begins in early adolescence has been well documented, and there has been considerable controversy regarding the reasons for this attrition. The present study addressed the attrition process by focusing on the subjective experience of sports as a function of grade, gender, and sport context. Following the procedures of the Experience Sampling Method, 401 5th–9th-grade boys and girls carried electronic pagers, similar to those worn by doctors, for one week, and filled out self-report forms on their activities and subjective states in response to signals received at random times. Older respondents spent less time in sports than their younger peers. This age difference was due primarily to a decline in informal sports participation, with less pronounced attrition from organized sports. Our findings suggest that the reasons for attrition from sport may be context specific. While informal sports were experienced more positively than gym class or organized sports, perceptions of skill were lowest during informal sports and declined with age. It seems youngsters stop participating in organized sports because these activities are less enjoyable to them, while attrition from informal sports is more performance based. Boys spent more time in sports than girls, and this difference was based primarily upon significant gender differences in informal sports participation. In spite of their differential rates of participation, boys and girls reported similar levels of affect, arousal, and skill during sports.This research was supported by NIMH grant number MH38324, Stress in Daily Life During Early Adolescence, awarded to Reed Larson, and was carried out while the first author was a Dissertation Fellow in the Department of Psychology at Loyola University of Chicago.Received Ph.D. in psychology from Loyola University of Chicago.

Classwork and homework in early adolescence: The ecology of achievement

Recent studies have questioned whether the nation's educational system is adequately preparing children to function productively in today's society. To examine this issue, the present study utilized the Experience Sampling Method to investigate the amount of time young adolescents spent doing classwork and homework, their inner subjective experience while doing so, and their companions while doing homework. The relationship between these variables and students' academic performance was also examined. Results revealed that students spent only 15.5 hours per week engaged in school work and only 6 hours per week doing homework, with increased homework time associated with better academic achievement. In addition, students were found to complete homework primarily alone or in classes, although doing homework with their parents was associated with better academic performance. Lastly, students' affect was found to be relatively neutral when doing classwork, but comparatively more negative while doing homework, particularly when doing homework alone. The implications of these findings for understanding the socializing influence of school are discussed.This research was supported by NIMH grant number MH38324, Stress in Daily Life During Early Adolescence, awarded to Reed Larson.

Validation of a 16-locus fluorescent multiplex system

STR multiplexes have been indispensable for the efficient genotyping of forensic samples. The PowerPlex 16 System contains the coreCODIS loci, D3S1358, D5S818, D7S820, D8S1179, D13S317, D16S539, D18S51, D21S11, CSF1PO, FGA, THOI, TPOX, vWA, the sex determinant locus, amelogenin, and two pentanucleotide STR loci, Penta D and Penta E. This multiplex satisfies the locus requirements for most national databases and is the most efficient currently available system due to its single PCR amplification. To provide the groundwork for judicial acceptance, including the publication of primer sequences, and to evaluate laboratory-to-laboratory variation, a developmental validation for casework on this commercially available system was performed in 24 laboratories and produced the following conclusions. Amplification was reliable on a variety of thermal cyclers and product could be analyzed on either an ABI PRISM 310 Genetic Analyzer or an ABI PRISM 377 DNA Sequencer. Genotyping using single source samples was consistent between 0.25 and 2 ng of input DNA template with a few laboratories obtaining complete genotypes at 0.0625 ng. However, heterozygote allele imbalance (<60% peak height balance) caused by stochastic effects was observed at a rate of 13% with 0.125 ng DNA and 22% at 0.0625 ng DNA. Mixture analyses were done using a total of 1 ng of DNA template. Most alleles were detected in mixtures of 4 to 1 and some minor alleles were detected in mixtures of 19 to 1. Optimum amplification cycle number was dependent on the sensitivity of the detection instrument used and could also be adjusted to accommodate larger amounts of DNA on solid supports such as FTA paper. Reaction conditions including volume, annealing temperature, and concentrations of primer, AmpliTaq Gold, and magnesium were shown to be optimal yet robust enough to withstand moderate variations without affecting genotype analysis. Environmental, matrix and standard source analyses revealed an ability to obtain complete genotypes in all sample types except those exposed to 80 degrees C for 12-48 days. Finally, comparison of genotype results from the PowerPlex 16 System with other commercially available systems on non-probative reference and forensic samples showed consistent results.     

Designing a merit‐based process for appointing boards of abcs: Lessons from the Nova Scotia reform experience

Abstract: Efforts to design merit‐based appointment systems for the boards of government agencies, boards and commissions (abcs) have gained greater priority over the past decade in order to enhance public confidence in the integrity of the political process, improve the governance of organizations operating at arm's length from ministers, and reduce the risks to the public interest and public purse that come with incompetent boards. The Nova Scotia reform experience in this regard is instructive because this province's appointment regime not only encompasses a legislative committee veto over ministerial appointments, a power unique to this province in the Canadian and comparative Westminster systems, but also uniquely sets the merit standard as relative‐merit, that is, the appointment of the most qualified of all applicants, and not merely a qualified candidate. This article reviews this provincial experience and concludes that a merit‐based appointment system that pursues relative merit can be created but only by restricting the authority of ministers to a veto over the appointment of candidates nominated by the abcs themselves. Sommaire: Ces dix demières années, les efforts déployés pour concevoir des systemes de nomination au mérite pour les conseils d'administration d'organismes, des régies et des commissions du gouvernement ont obtenu une priorité beaucoup plus grande, et cela, afin de rehausser la confiance du public envers I'intégrite du processus politique, d'ameliorer la gouvernance d'organismes fonctionnant sans contrôle ministériel direct et de réduire les risques que représentent les conseils incompétents pour le bien et les deniers publics. L'expérience de la réforme entreprise en NouvelleÉcosse est à cet égard instructive pour les partisans de la réforme. Le régime de nomination de cette province comporte non seulement un droit de veto de la part d'un comité législatif sur les nominations ministéielles, pouvoir unique à cette province dans le systéme canadien et le systéme comparatif de Westminster, mais il établit également la norme de mérite comme un mérite relatif, c'est‐à‐dire la nomination de la personne la mieux qualifiée parmi tous les candidats et non simplement la nomination d'une personne qualifiée. Le présent article examine I'expérience de cette province et conclut qu'un système de nomination au mérite visant le mérite relatif peut être mis en place, mais seulernent à condition de limiter le pouvoir des ministres à opposer leur veto à la nomination de candidats par les organismes, régies et commissions gouvernementaux.
