Ethnic and American Identity as Predictors of Self-Esteem Among African American,Latino, and White Adolescents

In order to examine ethnic and American identity as predictors of self-esteem among adolescents, we surveyed 669 American-born high school students (372 Latinos, 232 African Americans, and 65 Whites). Participants completed measures of self-esteem, ethnic identity, American identity, attitudes toward other groups, and demographic variables. Multiple regression analyses of self-esteem were carried out separately for each ethnic group, using ethnic and American identity, other-group attitudes, gender, age, socioeconomic status, and grade point average as predictors. Results indicated that for all groups ethnic identity was a significant predictor of self-esteem. For the White students only, American identity was a strong predictor of self-esteem and was highly correlated with ethnic identity. Other predictors varied across ethnic groups. Although ethnic identity was a significant predictor of self-esteem, it accounted for a relatively small proportion of the variance, suggesting the importance of other influences on self-esteem.     

The law and economics of organ procurement

This paper presents an economic analysis of the organ procurement system in the U.S. and examines proposals to alleviate the shortage of transplantable organs. The paper's principal conclusions are: (1) Although non-market solutions deserve the highest priority, demand increases fueled by improvements in transplant technology will probably make some market-based solution necessary in the future. (2) Quality deterioration and coercion will not necessarily be worrisome problems under a market-based procurement system.     

Self-determination as a universal human right

Conventional wisdom suggests that promoting self-determination for peoples and protecting the human rights of individuals are competing priorities. However, many recent international human rights documents include rights of peoples in their lists of basic human rights. In this paper, I defend including at least one people’s right, the right to self-determination, in the list of basic rights. Recognizing that self-determination is a constitutive element of human dignity casts state sovereignty in a different light, with interesting consequences both for international law and for philosophical debates about the rights of minorities.     

The Age Structure-Crime Rate Relationship: Solving a Long-Standing Puzzle

Objectives

Develop the concept of differential institutional engagement and test its ability to explain discrepant findings regarding the relationship between the age structure and homicide rates across ecological studies of crime. We hypothesize that differential degrees of institutional engagement—youths with ties to mainstream social institutions such as school, work or the military on one end of the spectrum and youths without such bonds on the other end—account for the direction of the relationship between homicide rates and age structure (high crime prone ages, such as 15–29).

Methods

Cross sectional, Ordinary Least Squares regression analyses using robust standard errors are conducted using large samples of cities characterized by varying degrees of youths’ differential institutional engagement for the years 1980, 1990 and 2000. The concept is operationalized with the percent of the population enrolled in college and the percent of 16–19 year olds who are simultaneously not enrolled in school, not in the labor market (not in the labor force or unemployed), and not in the military.

Results

Consistent and invariant results emerged. Positive effects of age structure on homicide rates are found in cities that have high percentages of disengaged youth and negative effects are found among cities characterized with high percentages of youth participating in mainstream social institutions.

Conclusions

This conceptualization of differential institutional engagement explains the discrepant findings in prior studies, and the findings demonstrate the influence of these contextual effects and the nature of the age structure-crime relationship.
