Assessment Center for Pilot Selection: Construct and Criterion Validity and the Impact of Assessor Type

Cette recherche a examiné la validité d'un centre d'évaluation pour la sélection de pilotes. Les scores de N = 1,036 participants ont été utilisés pour étudier la validité de construit. Un sous-échantillon de participants performants a été suivi et les évaluations des pairs ont été retenus comme mesures du critère. Les résultats démontrent une première évidence de validité de construit et de critère pour cet outil d'évaluation des compétences interpersonnelles et liées à la performance. Par ailleurs, les résultats ont aussi montré que le type d'évaluateur (psychologue vs pilote) modère la validité prédictive des scores du centre d'évaluation. Cet effet "type d'évaluateur" dépend de la sorte de variables prédictives. Les résultats sont discutés et des implications pratiques sont suggérées.
This study examined the validity of an assessment center in pilot selection as a new field of application. Assessment center ratings of N = 1,036 applicants were used to examine the construct validity. A subsample of successful applicants was followed up and peer ratings were chosen as criterion measures. The results provide first evidence of the construct and criterion validity of this assessment center approach for rating interpersonal and performance-related skills. Furthermore the type of assessor (psychologist versus pilot) moderates the predictive validity of the assessment center ratings. This type-of-assessor effect depends on the kind of predictor variables. The results are discussed and practical implications are suggested.     

Biased extensive measurement: The homogeneous case

In the homogeneous case of one type of objects, we prove the existence of an additive scale unique up to a positive scaling transformation without transitivity of indifference and with a property of homothetic invariance weaker than monotonicity. The representation, which is a particular case of a semiorder representation, reveals a unique positive factor α?1 that biases extensive structures and explains departures from these standard axioms of extensive measurement (α=1). We interpret α as characterizing the qualitative influence of the underlying measurement process and we show that it induces a proportional indifference threshold.     

WordGen: A tool for word selection and nonword generation in Dutch,English, German,and French

WordGen is an easy-to-use program that uses the CELEX and Lexique lexical databases for word selection and nonword generation in Dutch, English, German, and French. Items can be generated in these four languages, specifying any combination of seven linguistic constraints: number of letters, neighborhood size, frequency, summated position-nonspecific bigram frequency, minimum position-nonspecific bigram frequency, position-specific frequency of the initial and final bigram, and orthographic relatedness. The program also has a module to calculate the respective values of these variables for items that have already been constructed, either with the program or taken from earlier studies. Stimulus queries can be entered through WordGen’s graphical user interface or by means of batch files. WordGen is especially useful for (1) Dutch and German item generation, because no such stimulus-selection tool exists for these languages, (2) the generation of nonwords for all four languages, because our program has some important advantages over previous nonword generation approaches, and (3) psycholinguistic experiments on bilingualism, because the possibility of using the same tool for different languages increases the cross-linguistic comparability of the generated item lists. WordGen is free and available athttp://expsy.ugent.be/wordgen.htm.     

Canadian bulk water exports: Analyzing the sun belt conflict using the graph model for conflict resolution

A conflict over the proposed bulk export of water from Canada is systematically studied using the graph model for conflict resolution in order to illustrate how strategic conflicts of this type can be better understood and managed. The ongoing conflict involving a US company, Sun Belt Water Inc., and the Canadian federal and provincial governments is modeled and analyzed using the graph model methodology. This dispute reflects the kinds of controversies that can arise when international trade laws, which stress competition and profits, are in conflict with environmental and social laws. The Sun Belt conflict is especially interesting because of its evolution over several stages; at each stage of the conflict, the objectives of the disputants, and their strategic implications, can be realistically modeled and thereby investigated using the graph model. Amer Obeidi received his B.Sc. in Electrical Engineering from the University of Jordan in 1990 and M.A.Sc. in Management Sciences in 2002 from the University of Waterloo, Ontario, Canada. He is currently pursuing a PhD degree in the Department of Systems Design Engineering, at the University of Waterloo. His currents research interests include confrontation analysis, conflict analysis, negotiation, cognitive and emotional processes effect on decision making, and choice theory. Dr. Hipel’s major research interests are the development and application of conflict resolution and time series analysis techniques from a systems design engineering perspective. The main application areas of these decision technologies are water resources management, hydrology, environmental engineering and sustainable development. Dr. Hipel is the author/co-author of four books, nine edited books, many journal papers and is an associate editor of six international journals. Moreover, he is a professional Engineer and has carried out consulting activities with engineering firms, government agencies, and utilities in many countries. Director of the Laurier Centre for Military Strategic and Disarmament Studies, and Adjunct Professor of Systems Design Engineering at the University of Waterloo. Dr. Kilgour’s research interests lie at the intersection of mathematics, social science, and engineering. He has applied game theory and related formal techniques to analyze decision problems in international security and arms control, environmental management, negotiation and arbitration, voting, fair division, and coalition formation, and has pioneered the development of systems for decision support in strategic conflict. His most recent books are Perfect Deterrence (Cambridge) and Designing Institutions for Environmental and Resource Management (Edward Elgar).     

The similarity–attraction relationship revisited: divergence between the affective and behavioral facets of attraction

In contemporary attitudes‐and‐attraction research, attraction has been viewed as a multidimensional construct. Moreover, the effects of dissimilar and similar attitudes have been shown to vary with the facets of attraction measured. The hypotheses tested are that (1) only the proportion of similar attitudes relevant to the social context or interaction goals affects behavioral attraction (i.e. interpersonal distance between the participant and targets), and (2) the proportion of similar attitudes influences affective attraction (i.e. Byrne's attraction measure), regardless of attitude relevance. Two experiments were conducted with classroom activities (Experiment 1) and a writing workshop (Experiment 2) as the social contexts. The results of both experiments supported the hypotheses. Clearly, a solely affective measure of attraction seems inadequate for understanding the similarity–attraction relationship. Copyright © 2002 John Wiley & Sons, Ltd.
