A heuristic for the time constrained asymmetric linear sum assignment problem

The linear sum assignment problem is a fundamental combinatorial optimisation problem and can be broadly defined as: given an \(n \times m, m \ge n\) benefit matrix \(B = (b_{ij})\), matching each row to a different column so that the sum of entries at the row-column intersections is maximised. This paper describes the application of a new fast heuristic algorithm, Asymmetric Greedy Search, to the asymmetric version (\(n \ne m\)) of the linear sum assignment problem. Extensive computational experiments, using a range of model graphs demonstrate the effectiveness of the algorithm. The heuristic was also incorporated within an algorithm for the non-sequential protein structure matching problem where non-sequential alignment between two proteins, normally of different numbers of amino acids, needs to be maximised.     

Confronting Anxiety in Couple and Family Therapy Supervision: A Developmental Supervisory Model Based on Attachment Theory

Referencing relevant supervisory literature and attachment theory, this article presents a developmental couple and family therapy supervisory model that emphasises the efficacy of the supervisory relationship. Issues concerning anxiety, cognition and learning theory are addressed and phases in the supervisory process are identified and described. Cognitive, emotional and social development are linked to attachment theory and discussed in the supervisory context.     

Commitment in same-sex love relationships

This study sought to desribe and compare commitment structures among lesbian and gay male living-together relationships, and to develop an instrument which would measure different dimensions of commitment among gay dyads without some heterosexual biases inherent in traditional measures of interpersonal commitment. Questionnaire data collected from 32 lesbians and 50 gay males who had lived together for at least six months were factor analyzed, yielding three factors: (1) intradyadic commitment, (2) extradyadic commitment, and (3) commitment-as-trust. On all three of these indices the lesbians scored somewhat higher than did the gay males, but in fact there were surprisingly few significant differences between the gay men and the lesbians. Suggestions in the data that lesbians report somewhat less social supports and are more concerned with couple boundary maintenance, whereas gay males report somewhat more jealousy and dependency, are discussed in terms of their implications for such relationships.     

The effects of attire,location, and sex on aiding behavior: A similarity explanation

This study examined two distinct theoretical explanations for the effect of attire on aiding behavior. The reinforcing value of attire itself predicted that well-dressed persons would always receive more assistance than poorly dressed persons. The reinforcing value of perceived similarity predicted that similar persons would receive more assistance than dissimilar persons. Female confederates (N=17) who were well-dressed or poorly dressed approached males and females in an airport or bus station asking for a dime to complete a telephone call. Well-dressed confederates received more money at the airport; poorly dressed confederates received more money at the bus station. These results were interpreted as support for the similarity hypothesis.An earlier version of this paper was competitively selected to be presented to the communication theory interest group at the Central States Communication Association convention in St. Louis, Missouri, April 5–7, 1979.     

Cognitive-behavioral therapy for obsessive-compulsive disorder: review of treatment techniques

Obsessive-compulsive disorder (OCD) is a chronic, impairing condition with an estimated lifetime prevalence in adults of 2.5%. Controlled treatment trials have demonstrated that cognitive-behavioral therapy (CBT) is an effective intervention for OCD. However, many individuals diagnosed with OCD do not receive appropriate, empirically validated interventions, perhaps due to limited knowledge of CBT among mental health practitioners. This article provides a review of CBT for OCD. Issues related to treatment delivery and assessment are presented and highlighted by an individual example.     

Storming the ivory towers. A look at violence and stalking on campus

1. Organizations should establish workplace violence prevention policies and education programs. 2. Multidisciplinary teams should be established to address potentially violent situations. 3. Law enforcement or other experts should be consulted in stalking cases.     

Whither Risk Assessment: New Challenges and Opportunities a Third of a Century After the Red Book

Six multi‐decade‐long members of SRA reflect on the 1983 Red Book in order to examine the evolving relationship between risk assessment and risk management; the diffusion of risk assessment practice to risk areas such as homeland security and transportation; the quality of chemical risk databases; challenges from other groups to elements at the core of risk assessment practice; and our collective efforts to communicate risk assessment to a diverse set of critical groups that do not understand risk, risk assessment, or many other risk‐related issues. The authors reflect on the 10 recommendations in the Red Book and present several pressing challenges for risk assessment practitioners.
