Measures of Multigroup Segregation

In this paper we derive and evaluate measures of multigroup segregation. After describing four ways to conceptualize the measurement of multigroup segregation—as the disproportionality in group (e.g., race) proportions across organizational units (e.g., schools or census tracts), as the strength of association between nominal variables indexing group and organizational unit membership, as the ratio of between–unit diversity to total diversity, and as the weighted average of two–group segregation indices—we derive six multigroup segregation indices: a dissimilarity index (D), a Gini index (G), an information theory index (H), a squared coefficient of variation index (C), a relative diversity index (R), and a normalized exposure index (P). We evaluate these six indices against a set of seven desirable properties of segregation indices. We conclude that the information theory index H is the most conceptually and mathematically satisfactory index, since it alone obeys the principle of transfers in the multigroup case. Moreover, H is the only multigroup index that can be decomposed into a sum of between– and within–group components.     

Adolescent Personality as Risk and Resiliency in the Testosterone–Externalizing Association

Previous investigations of testosterone and externalizing behavior have provided mixed findings. We tested the hypothesis that self‐regulatory personality moderates the testosterone–externalizing behavior association in adolescence. Parents reported on their 13‐ to 18‐year‐old (N = 106, M_age = 16.01, SD = 1.29) children's personalities and psychopathology. Testosterone was measured via drool samples. As hypothesized, personality moderated the testosterone–externalizing behavior association. High testosterone predicted higher levels of externalizing behaviors, but only for adolescents low in Agreeableness and Conscientiousness. Also, personality acted as a resiliency factor: high levels of Conscientiousness, in the presence of high testosterone, predicted lower levels of rule breaking. Results highlight how endogenous factors, such as personality, may interact with testosterone, and emphasize the relevance of including personality moderators in future research.     

A Holland Perspective on the U.S. Workforce From 1960 to 2000

The authors analyze civilian occupations and employment data collected by the U.S. Census Bureau in 1960, 1970, 1980, 1990, and 2000 with respect to 6 kinds of work (Holland's RIASEC [Realistic, Investigative, Artistic, Social, Enterprising, Conventional] classification), employment, and gender. For the 1990 and 2000 censuses, kinds of work, gender, and income are analyzed, and for the 2000 census, kinds of work, age, and gender are examined. Past employment trends developed from census data are further analyzed with respect to Bureau of Labor Statistics employment projections through 2012. Implications for further research, employment policy, and career services are offered.     

The effect of the united mine workers of America on the probability of severe injury in underground coal mines

This paper examines the efficacy of the United Mine Workers of America (UMWA) in achieving safe working conditions by reducing the probability of severe injury. A detailed data base has been constructed for underground mines during the period 1986–1988. The results obtained fail to provide convincing evidence that the UMWA reduces the severity of injury, even though the UMWA has safety committees and inspectors in the mines where it is the bargaining agent. Further testing reveals that there is no significant difference in the probability of injury due to roof falls, haulage, and handling material, between union and nonunion mines.     

Using Profile Elevation to Increase the Usefulness of the Self‐Directed Search and Other Inventories

The authors explore the construct of profile elevation on interest inventories results. They speak to the need for career counselors to maximize their use of the interest inventory and how they can do that by properly interpreting profile elevation. Profile elevation is defined, and correlates of high and low profile elevation are presented. The common interpretive interaction that occurs between profile elevation and differentiation is explored. The authors also present a case of low profile elevation and the career counseling interventions and considerations used with the client.     

Career Decision State and Assessment of RIASEC Interest Structure

The career decision state (CDS) was studied in relation to RIASEC (Realistic, Investigative, Artistic, Social, Enterprising, Conventional) profiles in Self-Directed Search results among college students (86 women, 27 men). Three CDS dimensions measured by the Career State Inventory (CSI; certainty, satisfaction, and clarity) were examined as predictors of RIASEC primary and secondary constructs. Significant, albeit modest, zero-order correlations (p < .05) emerged between clarity and 3 secondary constructs (i.e., consistency, commonness, and coherence). Results of regression analyses indicated that CSI dimensions predicted 1 secondary construct (i.e., commonness).     

The Rise of Supermarkets in Africa: Implications for Agrifood Systems and the Rural Poor

The rise of supermarkets in Africa since the mid‐1990s is transforming the food retail sector. Supermarkets have spread fast in Southern and Eastern Africa, already proliferating beyond middle‐class big‐city markets into smaller towns and poorer areas. Supplying supermarkets presents both potentially large opportunities and big challenges for producers. Supermarkets' procurement systems involve purchase consolidation, a shift to specialised wholesalers, and tough quality and safety standards. To meet these requirements, producers have to make investments and adopt new practices. This is hardest for small producers, who risk exclusion from dynamic urban markets increasingly dominated by supermarkets. There is thus an urgent need for development programmes and policies to assist them in adopting the new practices that these procurement systems demand.     

The important role of mass media in the diffusion of accurate information about AIDS.

This paper explores the vital role of mass media in diminishing the lack of consensus among those at risk for AIDS and those who treat them. It examines the perceptions of these groups with regard to the seriousness of the AIDS threat, what people at risk are really doing to protect themselves and others, and the accuracy and objectivity of media reports about AIDS. Results indicate that there is a disarming lack of consensus among those people who can do the most to influence the spread of AIDS. Results also indicate that those people at greatest risk for AIDS and for spreading the disease distrust the accuracy and objectivity of the media. The authors argue that consensus is required for a concerted fight on AIDS and that the mass media offer an effective avenue for encouraging it. They also explore methods for regaining media respect among high risk groups with regard to AIDS reporting.     

Using Readiness Assessment to Improve Career Services: A Cognitive Information‐Processing Approach

This article begins with a review of the use of readiness assessment measures as a strategy for improving career services. A 5‐step process model for readiness assessment is then proposed and current readiness measures are identified. Although considerable research has been conducted on career decision‐making readiness and numerous measures have been developed, there has been limited literature available on the application of readiness assessment in selecting career interventions to meet specific client needs. This article continues with a theory‐based conceptualization of readiness and then links readiness assessment to the selection of career interventions designed to meet clients' needs.     

A Cognitive Approach to Career Services: Translating Concepts Into Practice

This article provides counselors with concept-based materials that clients can use to understand and structure the career problem-solving and decision-making process. Clients can use this knowledge to solve immediate career problems, transfer the knowledge to future career problems, or generalize the knowledge to other types of personal, social, and family problems.
