Enhancing the chances of successful OR/MS implementation: the role of the advocate

This paper extends understanding of the role of the advocate in the implementation of Operations Research/Management Science models in governmental agencies. The first part of this paper presents and analyzes the data resulting from interviews with 39 criminal justice agencies regarding the model implementation process. The interview data indicated that the advocate performed important problem-solving and mediation functions needed to introduce the technology. The second part of this paper provides a case study describing an advocate's successful introduction of a Patrol Car Allocation Model (PCAM) in the Los Angeles County Sheriff's Department. To assess the overall effectiveness of their implementation strategy, the project team conducted a questionnaire attitudinal survey of lieutenants, sergeants and officers in two of the pilot stations prior to PCAM implementation and after staffing changes. Overall, the attitude of the respondents was more favorable at the time of the second survey. The analysis of the interviews and the PCAM case study suggests a simple normative model for enhancing the chances of successful implementation of Operations Research/Management Science models.     

Child effects in socialization research: Some conceptual and data analysis issues

This paper examines issues associated with the conceptualization of child effects in socialization research and outlines possible data analysis strategies that may be used with contemporaneous correlational data from parents and children. The paper begins with an outline of some recognized prohlems in the studv of child effects. The role of cognitive factors, which complicate efforts to disentangle child effects, is emphasized, in an attempt to clarify further the meaning of child effect, three different types of effect are outlined and then a distinction is made between moderator and mediator variables. In general, a moderator variable specifies when certain outcomes will hold (e.g. for one type of child but not another), whereas a mediator variable indicates how or why the outcome occurs. The distinction between moderator-mediator variables provides the main focus of the paper. It assists in the conceptualization of child effects, as well as having direct implications for data analysis strategies. The relevance of the distinction is illustrated via data from a study of family relationships. The use of correlations, multiple regressions with interaction terms, and latent variable path analysis are examined as ways of investigating moderator and then mediator variables. Conclusions are reached about conceptual and data analysis difficulties associated with attempts to determine child effects.     

School-based interventions with depressed minority adolescents

School-based approaches to intervention with depressed minority adolescents is discussed within a preventive framework. The symptomatology and epidemiology of depression is presented as it pertains to minority group adolescents. Specific suggestions for school-based services, the uses of school-based mental health professionals, and for coordination with mental health agencies are provided.     

Voluntarism, self-help and rural community development: Some current approaches

Within the last decade or so, there has developed an increased concern for the welfare of rural communities and for individuals within such communities. At the same time there has emerged a parallel concern for environmental matters, concerned with conservation of species and habitat and the protection of cherished landscapes and amenities. Both sectors of rural concern have been characterised by debate about the means of delivery of policies and programmes in their respective areas and, in particular, about the balance between state action and the activities of the private sector. A common thread running through such debates has been the role of what is loosely called the ‘voluntary sector’, that is the complicated mix of individuals and organisations, local and national, which involve themselves in effort, not for direct payment nor as a routine of work, but because of feelings of commitment, belief and ideology.This paper is concerned with just one aspect of this sector — that which involves social and community aspects of the lives of rural dwellers in the English countryside. Despite this restricted field, there is an attempt to see things within a broader socio-political context, such that rural voluntarism and rural self-help can be assessed not only against a wider picture of volunteering generally but also placed within a political framework, both national and local. Voluntarism and self-help cannot exist independently of the world around them, yet the very process of facing up to the wider political realities creates problems of accountability and control to the extent that some would dismiss the voluntary sector as ineffective at best or the tool of vested interests at worst.     

NETWORK AND MEANING: AN INTERACTIONIST APPROACH TO STRUCTURE*

Social network is a concept interactionists might use to link individual behavior to the larger social system. A symbolic interactionist formulation of network would: 1) approximate the original, anthropological usage better than the current structural conception does, 2) offer symbolic interactionists a unit of social organization better suited to their perspective than the small group, and 3) allow symbolic interactionists to deal with “macro” sociological concerns. Network is conceived of as a set of relationships which people imbue with meaning and use for personal or collective purposes. By emphasizing subjective meaning and the investigation of multi-purpose and weak ties, the interactionist formulation provides theoretical insights into those aspects of society which “structural” approaches overlook.
