Latent classes and group membership

A technique for analyzing group membership data, such as interlocking directorates, based on the assumption of latent classes of individuals, is described and illustrated with two data sets. The technique partitions individuals and/or groups into homogeneous sets and can be used to create measures of structural centrality for groups and for individuals.     

Sociology and political arithmetic: some principles of a new policy science

This paper advances the position that sociology needs to develop an approach to research which focuses on fundamental social problems. In doing so it shares many of the intellectual values and goals of political arithmetic while seeking to move methodologically beyond it. Since such problems are complex they will require, typically, interdisciplinary input and a concomitant approach to the development and appraisal of theories. We are not, therefore, advocating the primacy of sociology but arguing that it has a distinctive part to play in addressing the fundamental problems of the twenty-first century. However, a policy-oriented sociology has also to take up the task, so clearly defined by the tradition of political arithmetic, which is to hold governments to account. Consequently a central principle of a new policy science is that it should contribute to democratic debate about policy.     

Breaking in a new function for casein kinase 2

DNA damage response mechanisms help ensure the fidelity of chromosomal transmission, and the failure of such mechanisms might lead to premature aging and cancer. A new report has established that casein kinase 2 (CK2), a protein that functions in diverse cellular processes, controls the activity of the DNA repair protein XRCC1. These results indicate that CK2 is a key participant in the cellular response to DNA damage.     

Mismatch of school desks and chairs by ethnicity and grade level in middle school

The purpose of this article is to introduce the cross-disciplinary competency standards for work-related assessments, why they are needed and how they have been developed in New South Wales (NSW). Cross-disciplinary competency standards communicate the benchmarks for effective performance of work-related assessments. They outline what is expected of rehabilitation professionals, including the ability to apply and transfer competence across different conditions and workplace contexts. Outcomes in occupational rehabilitation are affected by the efficacy of the work-related assessments performed, which is dependent upon competent, clinical decision-making by rehabilitation professionals. However, in Australia, work-related assessment practice is not governed by universally accepted competency standards or by any competency-based training/education and assessment system. To enhance professional practice, WorkCover NSW has developed cross-disciplinary competency standards for work-related a ssessments. The competencies provide (i) quality standards for professional workplace training and development, (ii) benchmarks for assessing the competence of rehabilitation professionals, (iii) a framework for evidence-based practice, (iv) benchmarks for measuring service quality and (v) "real world" learning outcomes and assessment criteria for professional education programs.     

Pretest-posttest designs and measurement of change

The article examines issues involved in comparing groups and measuring change with pretest and posttest data. Different pretest-posttest designs are presented in a manner that can help rehabilitation professionals to better understand and determine effects resulting from selected interventions. The reliability of gain scores in pretest-posttest measurement is also discussed in the context of rehabilitation research and practice.     

Confirming and Expanding the Usefulness of the Extended Satisfaction With Life Scale (ESWLS)

The role of stress, particularly economic hindrance,in the prediction of global life-satisfaction wascontrasted between typically younger (n = 109)and more mature (n = 66) undergraduate students. Participants completed a Personal Projects AnalysisAppraisal Matrix including six stress dimensions, aswell as a single-item measure of globallife-satisfaction. Discriminant function analysesconducted on the students' Personal Project appraisalsrevealed that project challenge and economic hindranceaccounted for 25% of the variability inlife-satisfaction for the mature students, but none ofthe stress dimensions predicted life satisfaction forthe younger students. These results indicate that therole of stress in the prediction of life-satisfactionvaries as a function of age, with project challengeand economic hindrance playing a significant role inolder students' lives. The results are discussed inrelation to the developmental context of personalprojects as life tasks and the varying contexts foracademic pursuit between mature and typically youngerundergraduate students.     

College and University Health Care Professionals: An Expanding Team

Abstract

Factors contributing to students' compliance with mass vaccination programs during meningococcal outbreaks have not been well described. A 1997 mass vaccination campaign at Michigan State University provided an opportunity to study such factors. Of 34 024 students in the target population, 17 538 (51.5%) were vaccinated in 5 days. Vaccination rates were higher for women (47.9%) than for men (43.1 %) and higher for on-campus residents (65.3%) than for off-campus residents (35.6%). For each year of students' age beyond 19, the adjusted odds of vaccination were reduced by 0.82. Adjusted odds ratios for vaccination, with White students as the reference group at 1.0, were 1.33 for Asian American students, 0.97 (not significant) for Hispanic students, 0.82 for African American students, and 0.80 for Native American students. Students from the Colleges of Business, Engineering, Communication, and Natural Science had the highest vaccination rates; those from the College of Arts and Letters had the lowest rates.     

The North American Career Development Partnership: Experiment in International Collaboration

This article describes how career development programs became the focus of an international partnership between the United States and Canada. Beginning in 1976 in the United States, the National Occupational Information Coordinating Committee (NOICC) and its State Occupational Information Coordinating Committees (SOICCs) developed training and materials that promote the use of occupational and labor market information. Similarly, in the early 1970s, Canada began to explore the feasibility of creating a computer‐based career information delivery system. What follows is the story of an unusual and significant international collaboration. It concludes with identification of lessons learned.
