South Korean adolescents' delinquency,disclosure, parental knowledge,parent–child closeness,and delinquent peer associations

The present study sought to examine longitudinal associations among delinquency, children's disclosure to parents, parent-child relationship quality, and parental knowledge in a South Korean sample. Longitudinal research shows that in Western samples, delinquency is negatively associated with the latter three variables. We also sought to test whether the associations varied across gender. We found little evidence of significant reciprocal relationships among the variables and no differences in associations across gender. A second analysis revealed that adolescents’ involvement with delinquent peers was a good predictor of subsequent delinquency for males and females. Implications of the findings for future research and practice are discussed.     

Truncation Bias and the Measurement of Income Inequality

An experiment designed to test whether experimenter observation influences play of the ultimatum game led to a comparison of proportions of perfect equilibria obtained under different conditions. Our analysis features a Bayesian approach to this comparison. Our method extends recent work in the nonparametric Bayesian analysis of bioassay problems when the prior constrains the form of the potency curve. Sampling-based approaches to calculating posterior features of interest are used and discussed. We conclude that experimenter observation has a small influence but not enough to account for most of the deviation from perfect-equilibrium play.     

Table of percentage points of ratios of linear combinations of order statistics of samples from exponential distributions

A form of the distribution function of ratios of linear combinations of order statistics of samples from an exponential distribution is given. From the distribution, tables of percentage points of the statistic for α = .05, .95, and n = 3(1)50, and for censoring up to five observations are presented. Use of the tables is made to find critical values of the most powerful scale and location invariant test of exponentiality against uniformity, and also to find critical values for a test of outliers in an exponential population.     

Culture of the Labor Movement and Work in the United States

With the resurgence of union organizing during the 1990s, a new scholarship about the labor movement has emerged, documenting and explaining this new social movement unionism. Literature on the culture of work is well developed while, generally speaking, in the scholarship about the labor movement, culture is an underdeveloped analysis. In this article, we look at the culture of market fundamentalism as the dominant way of thinking and explaining work and labor in the United States. Market fundamentalism has emerged at the same time that women and immigrants have become much more numerous among U.S. workers, and they have brought with them new cultural emphases at work and among unions. In response to market fundamentalism and with the activism of women and immigrants among others, unions have transformed their own culture toward social movement unionism and have pushed for a new culture of work.     

Neuropathology in Alzheimer's disease: awaking from a hundred-year-old dream

For one hundred years after Alois Alzheimer's first report of Alzheimer's disease (AD) in 1906, the pathological hallmarks of the disease, senile plaques and neurofibrillary tangles (NFTs), have been attractive targets for researchers. Therefore, not surprisingly, efforts to understand disease mechanisms have concentrated on the cell biology of amyloid-beta (Abeta) deposition as senile plaques or on the phosphorylation and aggregation of tau as NFTs. However, it now appears that this focus on pathology as a central contributor to disease may be misguided. Indeed, neurons associated with Abeta and NFTs in AD brain show a decrease in oxidative damage relative to those in vulnerable but morphologically intact areas of the brain, suggesting that neurodegenerative lesions are compensatory phenomena, and thus manifestations of cellular adaptation. That Abeta and tau accumulations indicate an age-related physiological reaction to chronic stress calls into question the rationale of current therapeutic efforts targeted toward lesion removal. Moreover, if this concept holds true for pathology in other neurodegenerative diseases, we may need to restructure our thinking and undergo a paradigm shift before substantial progress can be made in therapeutic intervention.     

FATHERS TAKING PARENTAL LEAVE AND THEIR INVOLVEMENT WITH CHILDREN

Parental leave has been promoted as a way to enhance employed fathers’ involvement with their children. Leave patterns, factors affecting these patterns and the impact of taking leave on involvement with children were assessed for fathers in 38 couples. Parents, contacted through their employers, completed self-administered questionnaires on their work schedule changes after the arrival of a baby, reactions to these changes, childcare activities and attitudes. The mother's and father's assessments in each couple were averaged to measure 21 different aspects of fathers’ involvement. Fathers who took leave were more likely to share some specific childcare tasks with mothers than fathers who did not take leave but no differences were found for time spent with children or taking responsibility for childcare. Parents’ equalitarian beliefs, income and education had more impact than taking leave on fathers’ overall involvement in childcare.

Se ha promovido La Licencia de Paternidad como una forma para ayudar a los padres que están empleados a involucrarse con sus hijos. Los patrones de estas licencias, los factores que afectan estos patrones, y el impacto que tiene esta licencia en las relaciones con los niños fueron evaluadas por los padres en 38 parejas. Los padres, contactados por sus empleadores, completaron cuestionarios sobre los cambios en sus horarios de trabajo después de la llegada del bebé, las reacciones a esos cambios, actividades para el cuidado del niño, y sus actitudes. Se hizo un promedio midiendo los 21 diferentes aspectos del involucro de los padres presentado en las evaluaciones hechas por la madre y el padre en cada pareja. Los padres que tomaron licencia de paternidad, generalmente compartieron con la madre algunos aspectos específicos para el cuidado del niño a diferencia de los padres que no tomaron la licencia, pero no se encontraron diferencias sobre el tiempo empleado con los niños o en las responsabilidades del cuidado de los mismos. En general, las creencias sobre la igualdad, la situación económica y la educación de los padres, tuvo más impacto que el involucrarse totalmente en el cuidado de los niños de los padres con licencia de paternidad.     

Unbinding Time: Alternate Work Schedules and Work-Life Balance

We examine the possibility that alternate work schedules affect perceived work-life imbalance—the time bind. The results show that alternate schedules per se do not unbind time. However, perceived control of work schedules increases work-life balance net of family and work characteristics. The most consistent family characteristic predicting imbalance is being a parent. The most consistent work characteristic predicting imbalance is hours worked. Once we control for hours worked, women and part-timers are shown to perceive more imbalance. Younger and better educated persons also perceive more work-life imbalance. However, they also report higher levels of schedule control and since schedule control improves work-life balance, it may be more important for unbinding time than schedule alternatives.     

Social Cocoons: Encapsulation and Identity Transformation Organizations*

The transformation of personal identities is an implicit or explicit goal of many organizations, including “new” religious movements, self-help groups, “deprogramming” enterprises, rehabilitation programs, and others. This essay describes and accounts for one important structural feature of identity transformation organizations (ITOs): encapsulation. Three types of encapsulation are described–physical, social, and ideological–and reasons why different ITOs emphasize certain types of encapsulation rather than others are suggested. Finally, we discuss how the need for encapsulation may conflict with other organizational imperatives of ITOs and we discuss the implications of this organizational dilemma for the successful functioning of ITOs.     

Letter to the Editor: A reply to Klein and Stern

Klein and Stern (hereafter KS-2007) have several problems withour article ("Is the Academy a Liberal Hegemony"), with themost general being their contention that we "misrepresent" theirwork. Most of this hinges on their claim that, while they studiedthe proportion of faculty who register or vote Democratic orRepublican (their D:R ratio), we treated this as equivalentto a measure of liberalism versus conservatism. KS-2007 go onto say that we "impute ideological content" to their resultswhile they themselves claim the intellectual high road as havingbeen very careful not to conflate voting or party registrationwith
