Practice and research in managing human systems—Four problems of relationship

Academic disciplines, it is argued, have structural reasons for remaining separate from each other. Professional schools, on the other hand, having a built-in test of relevance, draw what they need from different disciplines and are better equipped for inter-disciplinary work, even though they have problems in bridging professional boundaries. But the professions which manage human systems (management, government, planning, policy making) have no such support from the social sciences as, for example, medicine and engineering draw from the natural sciences. They have evolved powerful means of modelling complex human systems but they lack any adequate source of the assumptions needed for such models, since these are culture-determined and historically determined variables, far more dependent on specific time and place.The paper raises for discussion questions related to (a) the inter-relation of the social sciences; (b) their relation to the professional fields in which they might be applied; (c) their relation to the management sciences; and (d) the scope for an all-embracing general systems theory.     

The median voter model across levels of government

The median voter model provides a method of aggregating individual voter's demands to obtain community demand. Although higher level governments are often assumed to be less responsive to voters than lower level governments, it remains an open question whether or not the median voter model, which has been found to apply to the lowest tier of the federalist system, extends to higher level governments. We use the Cox specification test to find that the ad hoc model dominates the median model for counties and states. The county results are sensitive to the time periods, budgetary structure, and degree of urbanization.

The role of violence in street crime: a qualitative study of violent offenders

Studies on the motivation for violent street crime, such as robbery and assault, have tended to draw on either the rational choice or the subcultural perspective. This study explores the extent to which violence on the street can be explained by rational factors associated with the successful commission of the offence or social factors related to street culture. The study is based on qualitative interviews with 55 violent street offenders who were serving sentences for street robbery and assault in six prisons in the United Kingdom. The findings, based on accounts of 101 incidents of street violence, identified four main explanations for street violence: (a) successful offence enactment, (b) buzz and excitement, (c) status and honor, and (d) informal justice. The article concludes that there might be benefits in combining the insights of both perspectives by generating an integrated theory that would properly explain both the rational and the seemingly irrational components of street violence.     

Low-intensity community supervision for low-risk offenders: a randomized,controlled trial

The Philadelphia Low-Intensity Community Supervision Experiment provides evidence on the effects of lowering the intensity of community supervision with low-risk offenders in an urban, US county community corrections agency. Using a random forests forecasting model for serious crime based on Berk et al. Journal of the Royal Statistical Society, Series A, 172(Part 1), 191–211, 2009, 1,559 low-risk offenders were identified and randomly assigned to either standard or reduced frequency of mandatory office visits. Treatment as assigned was substantially delivered at 4.5 probation visits per year versus 2.4, for as long as offenders remained on active probation or parole. In a one-year follow-up for all cases, outcomes examined were the prevalence, frequency, seriousness and time-to-failure of arrests for new crimes committed after random assignment was implemented. No significant differences (p = .05) in outcomes were found between standard and low-intensity groups. Non-significant differences for offense seriousness favored the low-intensity group. We conclude that lower-intensity supervision at the tested level of dosage can allow fewer officers to supervise low-risk offenders in the community without evidence of increased volume or seriousness of crime.     

Effectiveness of hotline, advocacy, counseling, and shelter services for victims of domestic violence: a statewide evaluation

The authors report the results of an evaluation of services provided by 54 Illinois domestic violence agencies. In collaboration with the University of Illinois at Chicago evaluation team, domestic violence advocates identified services to be evaluated, specified desired outcomes of those services, and participated in developing measures of those outcomes in both English and Spanish. With in the limitations of the study, outcomes were positive in all four program areas: hotline, counseling, advocacy, and shelter. The authors then discuss implications for evaluation of domestic violence programs that maintain victim safety as a guiding principle.
