A Longitudinal Study of Self-Esteem: Implications for Adolescent Development

This study used a cluster analytic approach to identify self-esteem trajectories among adolescents over a four-year period from sixth to tenth grades (N = 1,160). Four self-esteem trajectories were identified that replicated previous research: (1) consistently high, (2) moderate and rising, (3) steadily decreasing, and (4) consistently low. Female adolescents were more likely to be in the steadily decreasing self-esteem group while male adolescents were more likely to be in the moderate and rising group. African American and white youth were equally distributed across groups. Using repeated measures analysis, we found that youth with consistently high and moderate and rising self-esteem reported developmentally healthier outcomes in Grade 10 than youth in the other two clusters. Outcomes included susceptibility to peer pressure, school grades, and alcohol use. Implications of these results for studying self-esteem and developmental change more generally are discussed.     

Disentangling the Weight of School Dropout Predictors: A Test on Two Longitudinal Samples

The aims of this study are to identify the most powerful predictors of school dropout and to determine how stable they are over time. Two generations of White French-speaking boys and girls from 12 to 16 years old (n = 791 in 1974, n = 791 in 1985) completed a self-administered questionnaire on their psychosocial adjustment at least one year before leaving school. As expected, the analyses showed that school, family, behavioral, social, and personality variables could all predict dropping out of school in the two samples. Furthermore, these predictors were quite stable over time. However, statistical improvement measures in logistic regression analyses indicated that school experience variables (i.e., grade retention, school achievement, school commitment) were the best screening variables for potential dropouts. The contribution of other psychosocial variables, even though significant, did not improve very much the capacity to identify who will drop out of school. The discussion highlights the implications of the findings for secondary prevention and screening practices.

Labor market experiences of low-income black women in middle-class suburbs: Evidence from a survey of gautreaux program participants

This article reports on a highly unusual experiment in racial and economic integration, the Gautreaux program. This program helps black families who are either current or former residents of public housing move into subsidized housing in Chicago and its suburbs. Surveying a random sample of 332 participants, we find that suburban movers are significantly more likely to have a job post-move than city movers, even among those who had never had a job before moving. Multivariate analysis shows that these differences are significant even after controlling for respondents' previous work history, human capital, and personal characteristics. These results suggest that low-income urban blacks experience significant gains in employment by moving to middle-class suburbs. Thus, housing assistance may be an effective alternative to traditional welfare-to-work programs.     

Discrimination Distress During Adolescence

Amidst changing patterns of accommodation and conflict among American ethnic groups, there remains a paucity of research on the nature and impact of racial and ethnic discrimination on development in multiethnic samples of youth. The Adolescent Discrimination Distress Index along with measures of caregiver racial bias preparation and self-esteem was administered to 177 adolescents drawn from 9th–12th graders self-identified as African American, Hispanic, East Asian, South Asian, and non-Hispanic white. Youth from all ethnic backgrounds reported distress associated with instances of perceived racial prejudice encountered in educational contexts. Instances of institutional discrimination in stores and by police were higher for older youth and particularly for African American and Hispanic teenagers. Encounters with peer discrimination were reported most frequently by Asian youth. Reports of racial bias preparation were associated with distress in response to institutional and educational discrimination and self-esteem scores were negatively correlated with distress caused by educational and peer discrimination. The importance of research on discrimination distress to understanding adolescent development in multiethnic ecologies is discussed here.     

Book Review: Facing the Decisions One Should Make and the Decisions One Wants to Make

Authors of two recent books, Smart Choices and The Win-Win-Solution, offer negotiation practitioners some new twists on how they can improve their decision-making processes. In the first book, Hammond, Keeney, and Raiffa present a five-part PrOACT system, which features: an assessment of the problem; determination of objectives; exploration of alternatives; comprehension of the consequences; and dealing with tradeoffs. The second book, by Brams and Taylor, outlines four settlement options that are available to decision makers, but advocates an adjusted winner approach. The authors have devised a system in which individuals' subjective assessments of particular items in dispute receive point totals, which can then be divided in an equitable manner. In effect, the authors show readers how to deal with the decisions they should make, and those they want to make.     

Sex differences in proximal humeral outline shape: elliptical Fourier functions

A method is presented for the numerical analysis of sex differences in size and shape of the proximal humeral outlines using elliptical Fourier functions (EFFs). A skeletal sample consisting of right and left humeri pairs of 69 individuals, 36 males and 33 females, was used. The proximal superior view in the plane of the proximo-distal axis of each humerus was photographed and then 54 boundary points were located on the two-dimensional outline tracings. These points were digitized and used to compute EFFs with 27 harmonics. From the EFFs, a set of expected points on the proximal humeral outline was generated using the centroid as an origin. Superimposition of the male and female outlines on this centroid provided a detailed picture of the relative sex differences in size and shape with respect to that center. The bounded area of the proximal humeral outline showed statistically significant sex differences. Additionally, statistical results of the amplitudes derived from the "area-standardized" EFFs and visual assessments of the mean outline plots indicated significant sex differences in shape of the proximal humeral outlines. Focusing on localized regional differences, the greater tubercle was located more postero-medially and the lesser tubercle was located more anteriorly in the males compared to the females. Sex determinations from the proximal humeri were also examined with discriminant functions based on the amplitudes, which represent shape characteristics of the outline, and the hounded area. Using a cross-validation method, predictions of the percentages of cases correctly classified with the discriminant functions were ranged from 92.8% to 95.7% for the right and left humeral data. These results suggest that differences in size and shape of the proximal humeral outlines may be better predictors of sex when compared with conventional measurements of the humerus.
