Stalking and psychological abuse: common factors and relationship-specific characteristics

The purpose of this study was to refine and elaborate models of personality and relationship-specific characteristics in the perpetration of stalking and psychological abuse. Three hundred and forty-two college students who had been in intimate relationships completed a series of questionnaires about their most recent breakup and their former relationship. Our hypotheses were supported, with harsh parental discipline, anxious attachment, and need for control of one's partner forming a common cluster in the prediction of stalking and psychological abuse. For psychological abuse, relationship dissatisfaction added to the predictive factors; whereas for stalking, the level of anger-jealousy over the breakup was the major added factor. Degree of anger-jealousy was influenced by being the recipient of a breakup and the level of passion.     

Book Reviews

This article examines some difficulties associated with the Haynes–Stone model and attempts to clarify how the model can be justified as representing the hypothesis that “quantity is demand determined and price is supply determined.” It also argues that the applications of such a model as was done by Haynes and Stone might not have resolved the controversies related to the Phillips curve and the supply function of exports (or imports).     

Science,measurement, and validity: Is completion of Samuel Messick's synthesis possible?

Messick's (1989) theory of test validity is profoundly influential (Hubley and Zumbo, 1996; Angoff, 1988) in part because it brings together disparate contributions into a unified framework for building validity arguments. At the heart of Messick's theory lies a synthesis of realism and constructivism with respect to both scientific facts and measurement. Within this synthesis there remains a tension between the evidential basis and the consequential basis for test interpretation and use. This cannot be sidestepped simply by limiting the evidential basis to test interpretation and the consequential basis to test use: Interpretation and use are not so easily held separate. The roles of constructivism and context in Messick's theory underline the inherent link between facts and values, but the assumption that facts are objective and values are subjective goes unquestioned in Messick's theory. The inherent link between facts and values combines with this assumption to produce the unresolved tension in Messick's theory. This suggests that a unified theory of test validity requires a theory of value justification.     

Measuring unemployment

The forecasts and assumptions of government and business regarding availability of labour are based in part on official statistics has been a matter of considerable debate in recent years. In this paper the author presents his views on the interpretation of the relevant U.K. statistics.     

A decision support system for the graph model of conflicts

A comprehensive decision support system called GMCA (Graph Model for Conflict Analysis) implementing the multi-player graph model for analyzing conflicts is developed. GMCA contains algorithms for the rapid computation of a wide range of solution concepts, thereby enabling decision makers to take account of the diversity of human behavior. Using an engineering case study, the key features of GMCA are illustrated.     

International alliance commitment and performance of small and medium-size enterprises: The mediating role of process control

Improving alliance performance is a critical issue that both managers and researchers have attempted to resolve. Recently scholars have suggested that firms can use alliance commitment and process controls to improve alliance performance. Yet research has only found weak support for these direct effects. In this paper we examine the mediating role of process controls on the relationship between alliance commitment and alliance performance. When tested on samples of SMEs we find support for our theoretical predictions. We then discuss the managerial implications of using commitment and process controls in SME international alliances.     

A case-based distance method for screening in multiple-criteria decision aid

Screening is a process of multiple-criteria decision aid (MCDA) in which a large set of alternatives is reduced to a smaller set that most likely contains the best choice. We propose screening using a distance model calibrated on the basis of the decision-maker's own judgement. Viewing MCDA as preference aggregation based on consequence data, we define consequence and preference expressions (values and weights) and describe how they are aggregated. Then we define screening and explain some of its properties. Using an appropriate definition of distance, our case-based distance method screens a set of alternatives using criterion weights and a distance threshold obtained by quadratic optimization using the decision-maker's selection of alternatives from a test set. This case-based method can elicit the decision maker's preferences more expeditiously and accurately than direct inquiry. An application in water supply planning is used to demonstrate the procedure.
