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. 相似文献

The concept of Hazard Analysis and Critical Control Point (HACCP) is a system that enables the production of safe meat and poultry products through the thorough analysis of production processes, identification of all hazards that are likely to occur in the production establishment, the identification of critical points in the process at which these hazards may be introduced into product and therefore should be controlled, the establishment of critical limits for control at those points, the verification of these prescribed steps, and the methods by which the processing establishment and the regulatory authority can monitor how well process control through the HACCP plan is working. The history of the development of HACCP is reviewed, and examples of practical applications of HACCP are described. 相似文献

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. 相似文献

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. 相似文献

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. 相似文献

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. 相似文献
