A Dynamic Model of Racial Competition, Racial Inequality, and Interracial Violence

Race relations and stratification literatures offer explicit expectations concerning interracial conflict. Causal arguments derived from these perspectives are examined in this study to explore their ability to explain interracial violence above and beyond criminological perspectives of economic deprivation and racial inequality. The vast majority of previous aggregate-level studies on violence are cross-sectional, ignoring the importance of a dynamic model that incorporates the influence of changing structural conditions in urban areas on interracial violence. We explore theories that incorporate dynamic explanations for the influence of structural factors related to crime as well as racial conflict and employ a methodological approach that models the change in structural conditions for rare events such as interracial homicide. We find that changes between 1980 and 1990 in urban Black and Hispanic population composition, racial competition and racial inequality differentially explain the variation in White and Black interracial homicide offending.     

THE USE OF CORRELATION IN LARGE SAMPLES

The asymptotic relative efficiency of Kendall's and Spearman's coefficients of rank correlation are considered for samples from a bivariate normal distribution and comments are made on the calculation of their variances. For large samples it is suggested that one should use mean values of the coefficients calculated by splitting the sample into a fairly large number of smaller samples. This reduces the amount of calculation required and the asymptotic relative efficiency of this procedure is found both for ρ= 0 and ρ≠ 0.

Women in the police: Integration or separation?

This study reports on the incorporation of female officers into the Atlanta Bureau of Police Services which until recently had an all-male occupational subculture. Fieldwork techniques included one-year of participant observation and the structured interviewing of 50 police officers.Findings indicated that women have been acculturated into the behavior and attitudes characteristic of the male police group. Specifically, they express increased cynicism and distrust of the public, and their behavior is abrupt with an unsympathetic demeanor. Conversely, women police officers have not been accepted as equally capable as male police officers by the latter. This discriminatory reaction results in a male overprotective attitude which is expressed in male domination of both detective and uniformed officers' work. These findings are congruent with the data from other studies which examined occupations in which women were numerically rare (tokens).The author concludes that because females emulate the male officers' ethos and behavior, and because they have not been accepted as equals in the police group, they have not greatly changed the male subculture of policing.     

Perceived income adequacy and selected financial management practices among families in Chile and Mexico

The purpose of this study was to explore the perceived adequacy of families' incomes and selected financial management practices (food budgetin debt, saving) in two Latin American countries. An interview survey was used to gather socioeconomic and demographic information from 537 families in Chile and Mexico. There were major differences between Chile and Mexico in the income adequacy responses and also major differences within countries between income levels. Implications of the findings for policy makers and curriculum planners who work in developing countries with inflationary conditions and income inadequacies are discussed.     

The use of constructive-developmental theory to advance the understanding of leadership

Constructive-developmental theory is a stage theory of adult development that focuses on the growth and elaboration of a person's ways of understanding the self and the world. In this article we review how the constructive-developmental frameworks of Kegan [Kegan, R. (1982). The evolving self: Problem and process in human development. Cambridge, MA: Harvard University Press], Torbert [Torbert, W. R. (1987). Managing the corporate dream: Restructuring for long-term success. Homewood, IL: Dow Jones-Irwin.], and Kohlberg [Kohlberg, L. (1969). Stage and sequence: The cognitive developmental approach to socialization. In D. Goslin (Ed.), Handbook of socialization: Theory and research. New York: Rand McNally] have been applied in the theoretical and empirical literature on leadership and management. Although the literature has produced a number of propositions, the notion that a leader's order of development should impact his or her leadership effectiveness or managerial performance has generated the most research. We found mixed support for this proposition as well as a number of limitations in the research in general. To have a greater impact on the leadership field, constructive-developmental theory needs to generate more robust research, to link more clearly with on-going streams of leadership research, and to explore the contribution of aspects of the theory beyond individual order of development.
