Angry drivers: a test of state-trait theory

Tested hypotheses from state-trait theory applied to anger while driving. College student drivers high in trait driving anger were compared to drivers low in trait driving anger. High anger drivers were more frequently angered in day-to-day driving (frequency hypothesis). They reported more intense anger in their most angering driving situations, when visualizing provocative driving events, and in day-to-day driving (intensity hypothesis). Driving diaries and surveys showed they engaged in more aggressive behavior and expressed their anger through more verbal, physical, and vehicular means (aggression hypothesis). They reported handling of their anger less well when visualizing provocative events and on the Adaptive/Constructive Expression scale (reduced adaptive expression hypothesis). They engaged in risky behavior (risky behavior hypothesis) and experienced more moving violations, close calls, and losses of concentration, but not more major or minor accidents (partial support for crash-related outcomes hypothesis). High anger drivers were more generally angry and impulsive and employed more negative, less controlled forms of general anger expression. Results supported state-trait theory and added to the literature showing that high anger drivers have some other psychological and behavioral characteristics that may interact negatively with anger behind the wheel.     

Intransitivities in multidimensional spatial voting: period three implies chaos

It is well known that multidimensional spatial voting can involve intransitivity and cycles, resulting in outcomes anywhere in the policy space. These results are typically referred to as the chaos theorems. In this paper, I show that the connection between non-equilibrium spatial voting and chaos is not merely semantic, but is theoretic. Using symbolic dynamics, I show that if a three-cycle intransitivity among social choices exists, then cycles of all lengths greater than three are possible. This result is then used to establish the three conditions of sensitive dependence on initial conditions, topological transitivity, and dense periodic points, demonstrating the formal connection between multidimensional spatial voting and chaotic nonlinear dynamics.     

Home Visiting Family Therapy for Children at Risk

Home visiting has a long history in the areas of health and welfare (Baldock, 1990: 121). Early intervention through home visiting programs has been found effective in preventing abuse and neglect in many countries including the USA (Olds, 1992), Ireland (Johnson, 1993) and Europe (Cox, 1993). The success of these programs lay in their effectiveness in reducing social isolation, improving parenting skills and enhancing self esteem. This paper reports on the role of family therapy in home-based early intervention for families with newborn infants.     

Seemingly unrelated reduced-rank regression model

Reduced-rank regression models proposed by Anderson [1951. Estimating linear restrictions on regression coefficients for multivariate normal distributions. Ann. Math. Statist. 22, 327–351] have been used in various applications in social and natural sciences. In this paper we combine the features of these models with another popular, seemingly unrelated regression model proposed by Zellner [1962. An efficient method of estimating seemingly unrelated regressions and tests for aggregation bias. J. Amer. Statist. Assoc. 57, 348–368]. In addition to estimation and inference aspects of the new model, we also discuss an application in the area of marketing.     

Social accounting as stakeholder knowledge appropriation

Heeding the call for socio-political explorations of the social accounting project, we use the analytical lens of knowledge appropriation to explore power and contest in social auditing. We develop a knowledge appropriation model comprising three stages: knowledge creation, knowledge generation and outcome distribution, which we then use to analyze an exemplar case. We argue that, despite asymmetries of power and managerial prerogative, deficient stakeholder involvement in the creation and distribution stages renders social auditing ineffective for governance as either a stakeholder account or a strategic management system. We conclude that embedded stakeholder involvement in knowledge creation processes is essential for social auditing to be effective as corporate governance.

Social Workers who Move into Private Practice: The Impact of the Socio-economic Context

Summary This paper is based on a doctoral research project, conductedin New Zealand between 1993 and 1999, that considered factorsin the movement of social workers into private practice (vanHeugten, 1999). The study employed a qualitative methodologyin which 33 private practitioners were interviewed using semi-structuredquestionnaires. All respondents had at least a first professionalqualification in social work. The research grew from a realizationthat there had been an upsurge in private practice since themid-1980s, during a time of increasingly right wing governmentpolicies, and free market philosophies. These policies and philosophiesled to a radical restructuring of government and not-for-profitorganizations that employed social workers. Some workers respondedto the changes by seeking alternatives to organizational employment.Concurrently opportunities for private practice were createdby the availability of third party payments for counsellingof survivors of sexual abuse and parties to marital disputes.A similar pattern of confluence of expanding social work privatepractice and free market ideology has been noted in countriessuch as Great Britain and Australia. The implications of thismovement into private practice are considered in relation toprofessional social work associations.
