A systematic approach to the construction of non-empty choice sets

Suppose a strict preference relation fails to possess maximal elements, so that a choice is not clearly defined. I propose to delete particular instances of strict preferences until the resulting relation satisfies one of a number of known regularity properties (transitivity, acyclicity, or negative transitivity), and to unify the choices generated by different orders of deletion. Removal of strict preferences until the subrelation is transitive yields a new solution with close connections to the “uncovered set” from the political science literature and the literature on tournaments. Weakening transitivity to acyclicity yields a new solution nested between the strong and weak top cycle sets. When the original preference relation admits no indifferences, this solution coincides with the familiar top cycle set. The set of alternatives generated by the restriction of negative transitivity is equivalent to the weak top cycle set.     

A systematic approach to smoking cessation activities in Danish shelters

Introduction: Shelter users have an alarmingly high smoking prevalence; our aim was to develop systematic smoking cessation activities in the shelters. Method: All available (n?=?13) shelters in Copenhagen were included. This Participatory Action Research had a development/test period and an implementation period for the revised intervention. Shelter-staff completed a questionnaire at baseline. Municipal smoking cessation counselors were trained to work with shelter users. Three types of on-site smoking cessation activities were developed and offered. Results: The estimated mean smoking prevalence in shelter users was 79%. Only two shelters ran smoking cessation activities prior to study start. All but one of the shelters implemented group-based intervention activities and approximately 13% of smokers signed-up; 26.6% of those who attended the first session were abstinent after approximately 12 weeks, as confirmed by staff. Conclusion: Smoking cessation activities in shelters are wanted by staff and shelter users, they are feasible and even very vulnerable persons are able to quit. Based on our experiences in Copenhagen shelters, we propose a systematic approach for future smoking cessation initiatives: smoking activities should be driven by the municipality, be pro-active, on-site, tailored and flexible, in addition, free nicotine therapy should be offered and trained smoking cessation counselors should be available.     

A systematic approach to increasing use of management-oriented program evaluation data

With the implementation of Management Information Systems (MISs) in human service delivery settings, came the expectation that managers would make data-based decisions. There is substantial evidence, however, that this has not occurred. The present authors describe a systematic approach to correcting this deficiency. The approach involves a behavioral definition of management information use, the identification of disruptions in the behaviors comprising information use, and an intervention designed to reduce disruptions and promote use. Conclusions about the effectiveness of this approach gained from its implementation in a community mental health center are described.     

Foster home recruitment: a market research approach to attracting and licensing applicants

Reports differ concerning the relative recruitment productivity of the various possible resources. This report from Hennepin County, Minnesota, of a three-year recruitment study involving a large sample, with well-detailed findings, offers much to be considered by foster family care services.     

A cultural approach to culture

Artifacts and Allegiances: How Museums Put the Nation and the World on Display takes a global approach to how museums make sense of increased globalization and migration. Museums construct narratives that link their locality to the nation and to the world. Peggy Levitt’s major book explains how museums imagine themselves and how they work towards composing a kind of visitor experience. It is about museum visions, missions, and exhibitions as told through the eyes of those who create and are responsible for them, namely, top administrators, curators, politicians, and more. Her analysis explains why museums only a few hundred miles apart can have such different conceptions of how to create the proper citizen. As such, the book illuminates the power of a cultural sociological approach.     

A developmental approach to resistance

Diagnosis, treatment and technical interventions are dependent on a theoretical interpretation of the behavior of a patient. The clinical material presented addresses an initial alternative assessment of resistances, not from a classical theoretical position of opposition to the analytic procedure, the defense of the neurosis and a safeguard against pain and danger, but behavior that expresses a developmental need and deficit in the patient that is expressed in the treatment and relationship to the therapist.     

A Kleinian approach to psychotherapy

This paper explores how certain key ideas of Melanie Klein regarding transference, separation, the significance of internal phantasy, the phenomenon of splitting internal objects, and experiences of greed, envy, and gratitude relate to the practice of psychotherapy. Problems of differentiating between persecutory and depressive anxieties as well as the defenses against specific anxieties, based on Klein's notion of the infantile roots of anxiety tied to loss, are discussed. The importance of attending to negative transference phenomena is elucidated. Implications of Kleinian theory for clinical social work practice and extended possibilities of work with asocial borderline and psychotic states are explored. How the therapist functions as a model of the biological mother is illustrated by case material of a borderline individual.     

The development of a systematic approach to mental health screening in Child Advocacy Centers

We report on efforts to implement a new protocol of mental health screening for children seen in Child Advocacy Centers (CACs), including the results from the first year of implementation with 1685 families. The parent-reported child screening results (obtained on 46.3% of children) indicate that while many children were not experiencing significant symptoms of internalizing or externalizing problems, a subset of children had very elevated scores. At the one-week and one-month screening, consistent predictors of more severe internalizing problems included age, a parent or step-parent as the offender, and having been removed from the home. For externalizing problems, consistent predictors included Caucasian ethnicity and having been removed from the home. By the one-week follow-up, about half of those interviewed (50.8%) had entered counseling or had an appointment pending. The likelihood of initiating mental health services was increased when the alleged abuse type was sexual, when the child had been removed from the home, and when the child's internalizing and externalizing symptoms were more severe. Surveys of the CAC staff implementing the new process suggest that it helped them understand the needs of the children, though their ability to reach some families was a barrier to implementation.     

A partitioning approach to structural balance

The classic formulation of structural balance by Cartwright and Harary (Psychological Review, 63, 1956, 277–293) had the basic structural theorem that a balanced structure could be partitioned into two mutually antagonistic subgroups each having internal solidarity. Davis (Human Relations, 20, 1967, 181–187) extended this theorem for cases where there can be more than two such mutually antagonistic subgroups. We use these theorems to construct a criterion function for a local optimization partitioning procedure for signed digraphs. For any signed digraph, this procedure yields those partitions with the smallest number of errors, a measure of the imbalance in the graph, and an identification of those links inconsistent with both generalized and structural balance. These methods are applied to some artificial data and to the affect data from Sampson (A novitiate in a period of change: An experimental and case study of social relationships, Dissertation, Cornell University, 1968). The latter provides a positive test of a basic tenet of balance theory, that there is a tendency towards balance with signed relations in human groups. While these methods can be applied to all signed digraphs and signed graphs, the balance hypothesis is relevant only for affect ties.     

A socio-economic approach to market transactions

The task of this article is to explore social underpinnings in economic exchanges. This exploration is undertaken within the frame of reference of socio-economics that centers on the multifarious social and cultural variables of economic phenomena. In particular, the socio-economic perspective on the market, focusing on the social setting of market exchanges, is utilized. As such, this exploration probes under the surface of (seemingly) cost-benefit induced exchange processes and uncovers a far more complex social structure and dynamics underlying these processes. Hence, these processes are analyzed as constituting socio-economic categories of the market. The social-cultural contingency of economic exchange, especially of its market varieties, is the key hypothesis of this article. This signifies that market exchange, just as production, distribution, and consumption, is a dependent variable on concrete social-historical conditions, rather than being a human universal. The approach proposed here provides an alternative to the purely economic conception, which treats exchange processes as strictly economic variables driven by an intrinsic logic and insulated from other social relations. The mainstream economic literature’s lack of consistent applications of such an approach to market exchange contrasts with the richness of such applications in the field of socio-economics. The paper’s aim is to contribute toward further elaboration and application of socio-economics.     

A contingency approach to nonprofit governance

A number of contingency factors may be relevant for effective nonprofit organizations and their boards. Although all boards must fulfill certain critical roles and responsibilities, strategic choices can be made about adopting different governance configurations or patterns. These choices can be meaningfully informed by understanding organizational contingencies such as age, size, structure, and strategy—and, even more important, by external contingencies and environmental dimensions such as degree of stability and complexity. This article extends or layers contingency thinking beyond its traditional focus on an alignment between the external environment and the organization's structure to focus as well on the alignment of the organization's governance configuration with its structure and environment. Structural contingency theory in general, and specifically within nonprofits, is reviewed. Two cases are presented of organizations that used an approach based on contingency theory in an action research process to examine and change their governance configurations. The steps they followed may help other nonprofits adapt their governance structures and practices and fulfill their responsibilities for board assessment and reflection.     

A strategic approach to managing crises

This article encorporates the management literature on crisis to create a model that can be used to assess the seriousness of crisis. In addition, the model is extended for use by public relations managers. The article concludes with suggestions that will modify approaches employed and improve the effectiveness of public relations professionals in their role as crisis managers.     

A team approach to practice teaching

The ideas presented in this paper were originally generated in a workshop at an NSPCC conference on Practice Teaching in March 1996. In this article we wish to develop some of these ideas further and explore the idea of a team approach to practice teaching. This is not some radical new notion, but an acknowledgement of the reality of many placements. Although a student will be allocated a practice teacher (and possibly an off-site practice teacher) he or she will not function by themselves but will be part of an organisation. It is this wider structure and its effects on the student that we feel needs closer scrutiny. Firstly, we believe that not enough attention has been given to the power that organisations can have over an individual (particularly one whose stay is only short-term and possibly part-time). Secondly, we believe students can obtain benefits from the wealth of knowledge existing in any team, drawing on the skills and expertise of all team members. When team learning works well we feel that it provides benefits for all parties - the student, the practice teacher, the team and service users.     

A strategic approach to labour inspection

In a report released in 2006, the ILO highlighted the difficulties of labour inspection in its member States and advocated a number of measures to strengthen its effectiveness. The author argues that inspectorates must go beyond calls for more inspectors by adopting a clear strategic framework for reacting to incoming complaints and targeting programmed investigations in order to maximize effectiveness in the use of their overstretched resources. To do so, he proposes, their work must be guided by the principles of prioritization, deterrence, sustainability and achieving systemic effects. The article concludes with an outline of the requirements of a coherent regulatory strategy.
