Parental Involvement Promotes Rural African American Youths’ Self‐Pride and Sexual Self‐Concepts

This study, an evaluation of the Strong African American Families Program, was designed to determine whether intervention‐induced changes in targeted parenting behaviors were associated with young adolescents’ development of racial pride, self‐esteem, and sexual identity. Participants were 332 African American mothers and their 11‐year‐old children in 9 rural Georgia counties. Families were randomly assigned to a control group or an intervention group. Unlike those in the control families, mothers in the intervention group reported increases in targeted parenting behaviors, which promoted self‐esteem, positive racial identity, and positive sexual self‐concepts among their children. These findings expand the study of African American youths’ identity development by including broader domains of identity and parenting processes other than racial socialization.     

关于孟子思想之新诠释--以政治思想为中心

孟子的“仁义论”是综合原始儒家的“仁”论与前期墨家“义”论而形成,但是孟子将“仁义”概念结合于他的“心性”概念,从而创造出新的涵义。由此,孟子政治哲学确立了超阶级的普遍性与道德对于世俗权利的优越性。我们将具备此含义的孟子之政治思想称为仁义的政治思想。我们将从以下三个方面进行探讨:仁义政治思想的基本内涵;构成仁义政治思想的思维方式;以及其思维方式所蕴涵的意义与问题。     

Social Environmental Variation, Plasticity Genes, and Aggression: Evidence for the Differential Susceptibility Hypothesis

Although G×E studies are typically based on the assumption that some individuals possess genetic variants that enhance their vulnerability to environmental adversity, the differential susceptibility perspective posits that these individuals are simply more susceptible to environmental influence than others. An important implication of this model is that those persons most vulnerable to adverse social environments are the same ones who reap the most benefit from environmental support. The present study tested several implications of this proposition. Using longitudinal data from a sample of several hundred African Americans, we found that relatively common variants of the dopamine receptor gene and the serotonin transporter gene interact with social environmental conditions to predict aggression in a manner consonant with differential susceptibility. When the social environment was adverse, individuals with these genetic variants manifested more aggression than other genotypes, whereas when the environment was supportive they demonstrated less aggression than other genotypes. Further, we found that these genetic variants interact with environmental conditions to foster various cognitive schemas and emotions in a manner consistent with differential susceptibility and that a latent construct formed by these schemas and emotions mediated the effect of gene by environment interaction on aggression.     

Corporate Involvement in Community Affairs*

An extensive monitoring of the Jones and Laughlin (J&L) steel mill in Hennepin, Illinois suggests that absentee-owned corporations have the ability to involve themselves in local community affairs while maintaining an illusion of non-involvement. Three techniques J&L employed to exert influence are described: unilateral actions, cooptation, and intervention. The failure of reputational leadership data to identify corporate influentials is used to suggest both the success J&L had in concealing corporate influence and the inadequacy of the reputational technique for fully identifying power structures in verticalized communities.     

How to Approximate a Histogram by a Normal Density

Which normal density curve best approximates the sample histogram? The answer suggested here is the normal curve that minimizes the integrated squared deviation between the histogram and the normal curve. A simple computational procedure is described to produce this best-fitting normal density. A few examples are presented to illustrate that this normal curve does indeed provide a visually satisfying fit, one that is better than the traditional , s answer. Some further aspects of this procedure are investigated. In particular it is shown that there is a satisfactory answer that is independent of the bar width of the histogram. It is also noted that this graphical procedure provides highly robust estimates of the sample mean and standard deviation. We demonstrate our technique by using data including Newcomb's data of passage time of light and Fisher's iris data.     

Algorithms for Computing the Sample Variance: Analysis and Recommendations

The problem of computing the variance of a sample of N data points {x_i } may be difficult for certain data sets, particularly when N is large and the variance is small. We present a survey of possible algorithms and their round-off error bounds, including some new analysis for computations with shifted data. Experimental results confirm these bounds and illustrate the dangers of some algorithms. Specific recommendations are made as to which algorithm should be used in various contexts.     

Stereotypes and retirement: A perspective from the palmore facts on aging quiz

This paper focuses on the stereotypes that elderly retirees hold of old age and the socioeconomic and sociodemographic factors associated with these beliefs. The Palmore Facts on Aging Quiz (FAQ) was administered to 224 retirees from a large corporation in the Southwest. The results show that this group of elderly retirees is less likely to stereotype the elderly or old age than are similar age samples administered the FAQ, but is still negative in the stereotypes it does hold.     

Relationships between personality variables and burnout: A meta-analysis

Abstract

Most burnout research has focussed on environmental correlates, but it is likely that personality factors also play an important part in the development of burnout. Previous meta-analyses, however, have been limited in scope. The present meta-analysis examined the relationship between personality and three dimensions of the Maslach Burnout Inventory (MBI): emotional exhaustion, depersonalization, and personal accomplishment. Consistent with our hypotheses, self-esteem, self-efficacy, locus of control, emotional stability, extraversion, conscientiousness, agreeableness, positive affectivity, negative affectivity, optimism, proactive personality, and hardiness, each yielded significant relationships with burnout. Type A Personality, however, was only related to personal accomplishment. Furthermore, regression analysis found that core self-evaluations, the Five-Factor Model personality characteristics, and positive and negative affectivity explained significant variance in each of the burnout dimensions. Finally, moderator analyses found several instances in which the strength of personality–burnout relationships depended upon whether burnout was assessed with the Human Services Survey of the MBI or the General Survey version of the MBI. It is concluded that employee personality is consistently related to burnout. Given the practical importance of employee burnout, it is recommended that personality variables be included as predictors in future research on burnout.
