METROPOLITAN STRUCTURE AND CRIMINAL VIOLENCE

This article re-examines the conclusions of an earlier paper (Blau and Blau. 1982);i.e., that racial inequality in metropolitan places increases criminal violence and is accountable for various factors to which this violence is often attributed, notably poverty, race, and the Southern subculture of violence. The replication confirms the basic original hypothesis that a Standard Metropolitan Statistical Area's (SMSA) racial inequality in socioeconomic status raises its rates of violent crime. This article also supports the earlier findings that rates of criminal violence are higher in larger SMSAs and in SMSAs with a great number of marital conflicts and disruptions (as indicated by the large proportion of divorced and separated), and that these rates are unrelated to an SMSA's poverty level once other conditions are controlled. However, when interaction effects and curvilinear relationships are taken into consideration, criminal violence is seen to depend considerably on an SMSA's racial composition and to be more prevalent in SMSAs with a largely Southern population than in others, which supports the thesis of a Southern subculture of violence.     

Pathways to productivity improvement

A study of productivity in the Machine Tool industry has just been published by the Engineering Employers Federation (EEF). As a member of the Productivity Steering Group, information was available to one of the authors, in an unusually detailed and validated form for the twenty or so individual companies, (though they remain anonymous). It was thought worthwhile to apply methods developed in the Economics and Statistics Department of British Aerospace to this data in order to give pointers to the factors explaining productivity differences. The particular methods referred to were those of the Diagnostic Chart, though considerably simplified to match the data available, and multiple regression analysis. Particular care is necessary in applying the latter technique in productivity analysis if spurious results are to be excluded. The conclusions were as follows: the most favoured path to improved productivity is via increased turnover; changes in productivity are reflected mainly in changes in the ‘profit’ element of value added rather than in the labour cost element; the major factor distinguishing low from high productivity companies is an excess of the manual work force in relation to turnover; increased fixed assets favours increased labour productivity; increased commitment to R & D favours increased labour productivity; these conclusions are, of course, deduced from a study of the machine tool industry in particular, but may well be of applicability to other industries.     

Occupational stress, and teachers in Northern Ireland

This article reports the results of a study of occupational stress undertaken with a large sample of Northern Ireland teachers, including qualified staff up to headteacher level. This study formed part of a wider interprofessional study of teachers, nurses and social workers.

The design and methods are described and demographic characteristics of the teaching sample are provided, with their views about teaching. Stressors are identified in both professional and private lives. The effects of stress as manifested through the General Health Questionnaire and the Maslach Burnout Inventory are examined and the teachers' views on various stress coping strategies are discussed.     

Transitions related to infection with human immunodeficiency virus (HIV)

Discovery of one's human immunodeficiency virus (HIV) infection, or receiving a diagnosis of acquired immune deficiency syndrome (AIDS), sets in motion a variety of transitions for individuals. Transitions may be characterized by changes in identity or role, changes in physical capacity and functioning, changes in outlook, changes in relationships, changes in routine, etc. Workplaces also face transitions to deal with increasing numbers of workers who are infected with HIV. A model for vocational rehabilitation counselors to assist individuals living with HIV infection in adjusting to their transitions is presented, and resources for providing informational support of individuals and organizations are described.     

Adapting the Own Children Method to allow comparison of fertility between populations with different marriage regimes

The Own Children Method (OCM) is an indirect procedure for deriving age-specific fertility rates and total fertility from children living with their mothers at a census or survey. The method was designed primarily for the calculation of overall fertility, although there are variants that allow the calculation of marital fertility. In this paper we argue that the standard variants for calculating marital fertility can produce misleading results and require strong assumptions, particularly when applied to social or spatial subgroups. We present two new variants of the method for calculating marital fertility: the first of these allows for the presence of non-marital fertility and the second also permits the more robust calculation of rates for social subgroups of the population. We illustrate and test these using full-count census data for England and Wales in 1911.
