Integrating research,policy, and practice in juvenile justice education

This article provides an overview of the history and context leading to Florida's efforts to implement an evaluation-driven research and associated quality assurance system for its juvenile justice education policies and practices. The Juvenile Justice Educational Enhancement Program began implementing Florida's evaluation research and quality assurance system to juvenile justice education in 1998. The article includes a brief summary of articles comprising this special issue of Evaluation Review that address the Juvenile Justice Educational Enhancement Program's various functions, methodological components, data, preliminary findings, continuing evaluation research efforts, and impediments.     

Evaluation research,policy, and politics

This article discusses the role of politics in the Juvenile Justice Educational Enhancement Program's effort to use evaluation research data to inform Florida's juvenile justice education policies and practices. Through consideration of the Juvenile Justice Education Enhancement Program's experiences with privatization and the tough love and economy of scale rationales for larger and more custodial juvenile institutions, the variable role of politics is examined. Although the two examples are different, the discussion demonstrates that by maintaining an overriding commitment to its evaluation research purpose, the Juvenile Justice Educational Enhancement Program has been able to continue its data-driven policy efforts despite operating in a politically charged environment.     

Fathers in child welfare: caseworkers' perspectives

Five focus groups substantially agreed about the lack of paternal participation in child welfare services and the reasons for low paternal involvement. The groups had considerable disagreement about whether child welfare professionals should address this issue. Some caseworkers believed that all fathers and mothers should be treated identically with respect to services to be offered and time frames for services; other caseworkers thought that the special circumstances of some fathers, such as lack of child care experience, called for service approaches that differ from those for mothers. Another disagreement was whether more fathers would be more involved if services were gender sensitive, that is, if agencies provided male caseworkers for fathers and had father-only services. Much of the debate focused on pragmatic considerations (would gender-sensitive services improve paternal participation and outcomes?), although some participants were concerned about equity (would such services give fathers an advantage in disputed custody cases?).     

The non-monetary quality of city life in South Africa

In contrast to most research on the non-monetary quality of life, which relies on subjective indicators, we construct objective measures of the non-monetary quality of life using regression methods, for South Africa's cities. We also analyse the extent to which the various cities have been able to turn improvements in per capita incomes (monetary quality of life) into non-monetary quality of life – as reflected for instance in a better environment, higher literacy and longer lives. When monetary quality of life measures are used for South Africa's cities, the ranking in 2004 was led by Johannesburg, Tshwane, Ekurhuleni, Cape Town, Durban and Port Elizabeth. However when residuals from a regression of per capita income on (HDI) are used as a measure of non-monetary quality of life (i.e. the proportion of HDI not explained by variation in incomes), coastal cities tend to obtain generally higher rankings, with Cape Town ranked first, followed by Ekurhuleni, Durban, Port Elizabeth and then Johannesburg and Tshwane.     

A profitability model for tactical planning

Simple models reflecting changes in aggregate company behaviour in response to changes imposed by management decisions and/or factors outside the direct control of management provide useful tools for tactical planning purposes.One such model is discussed in this paper. The model enables management to assess explicitly and quantitatively the effect on the rate of return on capital employed of primary causes of change in any of the key variables affecting company performance, such as the unit price, the unit cost, the output level and the capital employed. Simple functional relationships are proposed between the major variables in the model, such as the level of output and the unit cost, the unit price and the volume of sales, the working capital requirements and the general level of the firm's activity, etc. and these are based on analytical considerations, empirical evidence and a series of assumptions. These relationships give rise to a set of parameters which are incorporated in the model and describe the operational (cost structure), financial (capital structure) and marketing (elasticity of demand) position of the company under study.Numerical results obtained from the model seem to suggest that the sensitivity of the rate of return to some of the parameters and underlying assumptions is relatively small, implying that the inter-dependence between some of the variables can be ignored, thus simplifying the problems associated with data collection and model evaluation.Both the model and the methodology of analysis employed are flexible enough to allow: (1) application of the model to alternative sets of functional relationships between variables and/or underlying assumptions; (2) further decomposition of the model to include additional variables depending on the particular objectives of the study; (3) modification of the model to explore the effects of management decisions or those of changes in external factors on productive unit and product profitability; and (4) analysis of models reflecting the effects of changes which are imposed on the system on measures of business performance other than the rate of return on capital employed.
