Transitional phenomena in adolescence: Tools for negotiating the second individuation

The purpose of this article is to heighten clinicians awareness of the integrative potential of transitional phenomena in adolescent ego development. A review of the literature and presentation of clinical examples support the author's contention that adolescents may employ transitional phenomena to assist them through developmental turbulence reminiscent of original rap-prochement crises in early separation-individuation. An understanding of how adolescent clients may use transitional phenomena provides clinicians with an expanded perspective for differential assessment and intervention.     

THE REDUCED-RANK GROWTH CURVE MODEL FOR DISCRIMINANT ANALYSIS OF LONGITUDINAL DATA

This paper presents a method of discriminant analysis especially suited to longitudinal data. The approach is in the spirit of canonical variate analysis (CVA) and is similarly intended to reduce the dimensionality of multivariate data while retaining information about group differences. A drawback of CVA is that it does not take advantage of special structures that may be anticipated in certain types of data. For longitudinal data, it is often appropriate to specify a growth curve structure (as given, for example, in the model of Potthoff & Roy, 1964). The present paper focuses on this growth curve structure, utilizing it in a model-based approach to discriminant analysis. For this purpose the paper presents an extension of the reduced-rank regression model, referred to as the reduced-rank growth curve (RRGC) model. It estimates discriminant functions via maximum likelihood and gives a procedure for determining dimensionality. This methodology is exploratory only, and is illustrated by a well-known dataset from Grizzle & Allen (1969).     

A Tale of Two Border Cities: Community Context,Ethnicity, and Homicide*

Objective. Using Poisson‐based negative binomial regression, we estimate the effect of neighborhood factors on homicides in two cities (San Antonio, Texas and San Diego, California) that have large Mexican‐origin populations. Methods. Three independent data sources (official homicide police reports, medical examiner records, and the U.S. Census) are used to construct the dependent homicide, and independent neighborhood, variables. Census tracts represent the unit of analysis, which serve as a proxy for neighborhoods. Given the spatial nature of the data, spatial estimation procedures were also modeled. Results. Spatial proximity to violence, neighborhood disadvantage, and affluence (in San Antonio) consistently buffered homicide across neighborhoods, even in heavily populated Latino neighborhoods. Conclusions. Spatial embeddedness and neighborhood characteristics are important for improving our understanding about ethnic neighborhood variations in levels of violence. Comparative approaches across places, namely, Latino‐dominated cities, can yield considerable insight into how the local context intersects race/ethnicity and violent crime.     

Acyclic social choice from finite sets

This paper characterizes acyclic preference aggregation rules under various combinations of monotonicity, neutrality, decisiveness, and anonymity, in the spirit of Nakamura's (1979) Theorem on the core of simple games. Each of these characterizations can be seen to follow from Ferejohn and Fishburn's (1979) result on acyclic aggregation rules assuming only independence of irrelevant alternatives. We then state as corollaries to these characterizations extant results such as Sen's (1970) liberal paradox, Blau and Deb's (1977) theorem on the existence of vetoers, and Brown's (1975) theorem on the non-emptiness of the collegium.I thank David Austen-Smith, Michel Le Breton, Maurice Salles, and two anonymous referees for numerous enlightening conversations and comments.

Self-Esteem and Low Status Groups: a Changing Scene?*

To insure the widest possible test of the hypothesis that individuals with lower ascribed or achieved status will demonstrate lower levels of self-esteem than higher status individuals, 972 subjects completed questionnaires which included the Rosenberg Self-Esteem Scale. North Florida residents were sampled using a disproportionate stratified random sampling technique. Seven groups were identified: psychiatric patients, prisoners, black or white college students, city residents, married black residents, and service-oriented professionals. When analyzing data for each group, the results indicated that persons with lower ascribed status (blacks, females, and older Americans) did not, as a group, have lower self-esteem scores than persons with higher ascribed status (Whites, males, and younger Americans). However, persons with lower achieved status in the areas of educational attainment and occupational prestige did have lower self-esteem scores than did persons of higher status. Further, having an institutionalized status—confinement at a state psychiatric hospital or a maximum security prison—is correlated with low self-esteem scores. Some possible explanations of these findings are explored.     

Labor market adjustments in the unionized contract construction industry

The unionized construction labor market reaches equilibrium by means of three adjustment mechanisms: wage changes, changes in the quality of workers hired, and the migration of workers in and out of the market. The relative importance of the three mechanisms in local labor markets depends on laws and institutional rules. This paper examines some of the important institutional rules and presents a model of market clearning where wage adjustments are infrequent.
