Continuation of exchange with neighbors in later life: The importance of the neighborhood context

Relationships with neighbors are considered exchange relationships, in which the continuation of exchanges depends on balance in previous exchanges. Our study tested whether this is the case. An exchange relationship implies that neighbor relationships are isolated units. We expected, however, that neighborhood integration also affects the continuation of exchange among neighbors. Data were from a longitudinal study among 1,692 independently living Dutch adults of ages 55 to 85 years at baseline and their 7,415 relationships with proximate network members. At a four–year follow–up, both perceived balance and neighborhood integration at baseline increased the chance of instrumental support exchange occurring. We concluded that it is too limited to view relationships between neighbors as exchange relationships, as these relationships are embedded in larger communities, where such communities exist.     

An Examination of the Actor-Observer Effect in Young Drivers' Attributions for Their Own and Their Friends' Risky Driving

The attributions of 70 young drivers for their own and their friends' risky driving were examined using open-ended questions to determine if there were self-other differences consistent with the actor-observer effect. Six response categories were created, 4 of which were rated as more dispositional than situational by a subsample of the participants and 2 of which were rated as more situational than dispositional. While the largely dispositional category "Showing off, acting cool" was used significantly more for friends than for self, and the largely situational "In a hurry, late" was used significantly more for self than for friends, there was only limited support for the actor-observer effect overall. The participants also rated their friends as taking more risks than themselves. The actor-observer differences are suggested to be influenced primarily by motivational factors and the context in which young people observe their friends' driving. New approaches to traffic safety interventions are suggested.     

Reliability and construct validity of the Dutch psychopathy checklist: youth version: findings from a sample of male adolescents in a juvenile justice treatment institution

The present study examines the reliability and construct validity of the Dutch version of the Psychopathy Check List: Youth Version (PCL:YV) in a sample of male adolescents admitted to a secure juvenile justice treatment institution (N = 98). Hare's four-factor model is used to examine reliability and validity of the separate dimensions of psychopathy. Interrater reliabilities are good to excellent for the PCL:YV total score and most factor scores, except for the affective factor. Several suggestions are offered for optimizing reliability of this factor. Finally, meaningful associations between PCL:YV scores and scores on the Minnesota Multiphasic Personality Inventory-Adolescent and the Interpersonal Checklist-Revised support the construct validity of the PCL:YV total score as well as the four factors in the Dutch context.     

Large sample validations of three general predictors of pilot training success

This article addresses one of the perennial problems of pilot selection research: obtaining an adequate sample size for reliable statistical analysis of predictive validity. Results from three studies involving the same computerized tests of instrument comprehension and psychomotor ability were combined in a meta-analysis to determine whether the validities of these tests generalized across three contexts. These were Royal Air Force and Turkish Air Force fixed-wing pilot training and British Army Air Corps rotary-wing pilot training. In this article, we discuss the adequacy of samples for estimating the validity of the tests, and the persistence of predictive validity to later stages of training as shown by British Army Air Corps data. Reference is also made to data from a fourth independent study of Qantas pilot training.     

Naive and refined truth approximation

The naive structuralist definition of truthlikeness is an idealization in the sense that it assumes that all mistaken models of a theory are equally bad. The natural concretization is a refined definition based on an underlying notion of structurelikeness.In Section 1 the naive definition of truthlikeness of theories is presented, using a new conceptual justification, in terms of instantial and explanatory mistakes.In Section 2 general constraints are formulated for the notions of structurelikeness and truthlikeness of structures.In Section 3 a refined definition of truthlikeness of theories is presented, based on the notion of structurelikeness, using a sophisticated version of the conceptual justification for the naive definition.In Section 4 it is shown that idealization and concretization is a special kind of potentially refined truth approximation.I would like to acknowledge that van Benthem (1987) played in several respects a crucial role in the research for a new refined definition. Moreover, I like to thank David Miller, Ilkka Niiniluoto, and two referees for their comments on an earlier version. One of the referees notes that the Miller version of the naive approach (in model-theoretic terms, and identifying the truth with the truth about the actual world) has been criticised on several occasions for its failure to accommodate likeness between structures by Oddie (notably Oddie, 1986). The idea that likeness between structures should be a guiding idea behind truthlikeness is said to be a constant theme of Oddie's work. All this may well be true, but I should add however that Oddie's publications did not play any role in my research. The local references to Oddie are based on the suggestions by the referee.     

J.L. Moreno: An Unrecognized Pioneer of Family Therapy

J.L. Moreno's fundamental and pioneering contributions to the development of group therapy, encounter, transactional analysis, and especially psychodrama are well known. However, most family therapists seem unacquainted with the fact that from his earliest writings in 1923 J.L. Moreno developed an interactional view of psychotherapy that in 1973 already resulted in formulations of a true systems orientation and very concrete ideas about marital therapy, family therapy, and network therapy. He probably is the first (1937!) therapist that actually involved a husband's lover in conjoint marital therapy. His general theoretical formulations about the pathology of interpersonal relations as well as his practical suggestions for the therapy of the interpersonal relations seem to be insufficiently known to workers and researchers in the field of family therapy.     

Overpayment: Perceived qualifications and financial compensation

In this study expectancy and equity theory were compared. An experiment was carried out on the effect of overpayment. Overpayment was manipulated by varying perceived input (perceived qualifications) and received outcome (financial compensation). The experiment consisted of a 2 × 3 design: two levels of payment (4 guilders p.h. and 8 guilders p.h.) and three levels of perceived qualifications (high, medium, low). Sixty-six subjects were hired through the students placement service to decode personality questionnaires. Overpayment by manipulation of monetary rewards did not lead to greater production, as was hypothesized by Adams' equity theory (1965). As far m overpayment has been manipulated by perceived qualifications for the job the data confirmed equity theory. Several other theories (e.g. expectancy theory: Lawler, 1968b) can explain both results.
