Adolescent Self-Esteem and Gender: Exploring Relations to Sexual Harassment, Body Image, Media Influence, and Emotional Expression

Self-esteem plays a central role in mental health, yet not enough is known about how youth evaluate themselves as they move across adolescence. This study used a cross-sectional design to examine age and gender patterns in self-esteem and to explore how contemporary social influences relate to adolescent self-esteem. Self-reported influences on self-esteem involving the media, sexual harassment, body image, family and peer relationships, and emotional expression were evaluated with 93 boys and 116 girls in Grades 5, 8, and 12. Girls reported lower self-esteem than boys in early adolescence, and late adolescent boys reported lower self-esteem than younger boys. The predictors as a set accounted for a significant portion of the variance in self-esteem, while the best predictor of self-esteem varied by age and gender. Large gender differences were present for emotional expression, with boys becoming more restrictive across adolescence. Girls reported more negative body image and media influence scores than did boys in late childhood and early adolescence. Body image appeared to mediate the relationships between certain predictors and self-esteem for girls, while gender and grade appeared to moderate the relationship between media influence and self-esteem for girls and boys.     

A China Divided since the Turnover of Political Power in Taiwan

Since March 2000 the turnover of political power in Taiwan to the Democratic Progressive Party (DPP) and President Chen Shui-bian has been associated with a bitter clash between two visions for Taiwan's future: a vision of Taiwanese nationalism promoted by President Chen and the DPP versus one of engagement with mainland China that aims to create a special relationship while engaging the Western world, as promoted by the KMT and some of its allies. These conflicting visions will continue to interact and influence political life in significant ways.     

DSM-III diagnoses and offenses in committed female juvenile delinquents

The relationship between juvenile delinquency and psychiatric disorders remains poorly understood. However, it is becoming more apparent that the spectrum of psychiatric illness present in juvenile delinquents is broader than once believed. Fifteen female juvenile delinquents committed to a residential treatment program were assessed for DSM-III diagnoses, using a structured diagnostic interview, the Diagnostic Interview for Children and Adolescents (DICA). A search of the literature revealed no other reports using the DICA in female juvenile delinquents. A broad spectrum of current and past diagnoses was discovered, including conduct disorder (100%), substance abuse/dependence (87%), major depression (67%), and anxiety disorders (47%). The average number of lifetime diagnoses per subject was 4.7; current diagnoses averaged 3.4 per subject. Additionally, criminal and status offense records were obtained for each subject. No significant relationship was noted between diagnoses and categories of offense. These results add further evidence for the presence of frequent and severe psychiatric disturbances in this population, and the need for increased clinical and research efforts by the psychiatric community.     

Statistical tests of discrimination in punishment

A method, adopted from the labor econometrics literature, is proposed for detecting discrimination in punishment. The method requires the separate estimation of time served and punishment probability equations for, say, whites and blacks. The coefficients from the white equation are used to predict the punishment blacks would receive if treated like whites. A test of no discrimination against blacks is a test that the black punishment predicted by the black equation is equal to the punishment predicted by the equation using the white coefficients but the black endowments or characteristics. A further test is proposed that evaluates the economic efficiency of disparities in punishment. The test is restricted to measuring the recidivism effect of equality of treatment in punishment. The discrimination test and the efficiency test are illustrated using the U.S. Board of Parole data for 1972. Statistically significant racial disparities in punishment are uncovered and are found to be economically inefficient.     

Macroscopic observations of the effects of varying fresh water pH on bone

Little is known about the decomposition of remains in aquatic environments of varying pH, and even less is known about the specific effects of these environments on bone. Bovine bones were placed in solutions of pH 1, 4, 7, 10, and 14 and observed over a period of 1 year. All solutions eventually removed or dissolved the soft tissues from the external surface of the bone. The pH 7 and pH 10 solutions had little effect on the bone, but the other solutions affected the bone to varying degrees. Extreme pH levels were the most destructive, while more moderate pH levels had lesser but significant and interesting effects. Empirical data on postmortem aquatic changes may be extremely useful in forensic contexts for both improving time since death estimates and also for providing better information to underwater recovery experts thereby potentially increasing the quantity and quality of remains recovery.
