Go with the flow: How children's persuasion knowledge is associated with their state of flow and emotions during advergame play

This study investigates children's persuasion knowledge towards an advergame. Based on the theory of limited capacity and the PAD dimensions of emotions (i.e. pleasure, arousal and dominance), we propose a model in which persuasion knowledge is associated with game flow, and in which game flow is subsequently related to self‐reported player emotions. To test this model, 200 respondents between 7 and 12 years old were asked to play an advergame and to complete a survey addressing self‐reported emotions, persuasion knowledge and game flow. Structural equation modelling partially confirms our model. Both managerial and ethical implications are discussed in the paper. Copyright © 2015 John Wiley & Sons, Ltd.     

Cross‐cultural Generalizability of the Alternative Five‐factor Model Using the Zuckerman–Kuhlman–Aluja Personality Questionnaire

Several personality models are known for being replicable across cultures, such as the Five‐Factor Model (FFM) or Eysenck's Psychoticism–Extraversion–Neuroticism (PEN) model, and are for this reason considered universal. The aim of the current study was to evaluate the cross‐cultural replicability of the recently revised Alternative FFM (AFFM). A total of 15 048 participants from 23 cultures completed the Zuckerman–Kuhlman–Aluja Personality Questionnaire (ZKA‐PQ) aimed at assessing personality according to this revised AFFM. Internal consistencies, gender differences and correlations with age were similar across cultures for all five factors and facet scales. The AFFM structure was very similar across samples and can be considered as highly replicable with total congruence coefficients ranging from .94 to .99. Measurement invariance across cultures was assessed using multi‐group confirmatory factor analyses, and each higher‐order personality factor did reach configural and metric invariance. Scalar invariance was never reached, which implies that culture‐specific norms should be considered. The underlying structure of the ZKA‐PQ replicates well across cultures, suggesting that this questionnaire can be used in a large diversity of cultures and that the AFFM might be as universal as the FFM or the PEN model. This suggests that more research is needed to identify and define an integrative framework underlying these personality models. Copyright © 2016 European Association of Personality Psychology     

Nodule Detection with Eye Movements

Radiologists often miss nodules that may represent lung cancer on chest radiographs. We investigated whether eye movements collected during the search for lung nodules by large samples of laypeople may provide information that could assist radiologists in their detection. For that purpose, we developed a partially invisible Markov model with partially unobserved states and analyzed eye tracking data of over 100 laypeople who reviewed 14 chest X‐ray images, of which seven contained a potentially cancerous nodule. We used the luminance value of the pixels in the X‐ray images as prior information on the possible location of a nodule and identified six regions of interest on each image that may contain a nodule. Our study demonstrated that the eye movements recorded from laypersons contained information that may assist radiologists in the detection of nodules in chest X‐rays, which has important implications for crowdsourcing of search for pulmonary nodules, which are discussed.

Assessing risky public investments with MUSTARD

This paper presents a practical implementation of multicriteria methodologies based on the UTA model by Jacquet‐Lagrèze and Siskos and Quasi‐UTA model by Beuthe and Scannella, which are specified with a non‐linear, but piecewise linear, additive utility function. In contrast with the general UTA model, the Quasi‐UTA specification structures the partial utilities as recursive exponential functions of only one curvature parameter. This allows for a reduction of the quantity of information necessary to build the utility function. The software MUSTARD implements different variants of these models. Firstly, it offers the basic deterministic UTA model of disaggregation, but also its first programmed stochastic version. In both cases, the software proceeds stepwise and interactively helping the decision maker to formulate the problem and state preferences between projects; in the stochastic case, the decision maker is even helped to build the criteria distributions. The Quasi‐UTA specification can be introduced in this disaggregation model. Secondly, the software offers an aggregation model whereby the Quasi‐UTA partial utility functions are built separately through specific questioning processes. The questions relating to deterministic criteria are of the ‘direct rating type’, while those of the stochastic criteria are either of the ‘variable probability’ or the ‘variable outcome’ type. The criteria weights can be assessed by the ‘swing weight’ method or by a UTA‐II side‐program. As an example as well as a test of the Quasi‐UTA aggregation approach, the paper presents its application to a real problem of selecting road investment projects in Belgium. Several experts and civil servants were interviewed, and their individual utility functions derived. The projects are ranked according to their rate of return, which is computed on the basis of the projects certain equivalent money value. Copyright © 2002 John Wiley & Sons, Ltd.     

Undercover probes of police corruption: risk factors in proactive internal affairs investigations

The targeting of selected police officers for proactive undercover investigations is being championed by Internal Affairs (IA) who see it as an innovative corruption prevention program. A critical look at this program suggests that IA's discretionary powers and lack of decisionmaking guidelines for initiating administrative undercover investigations risk adverse legal, social, and ethical consequences. The role of cognitive and organizational factors on police managers' decisions to initiate internal undercover investigations was studied empirically. Three cases of police misconduct involving a shake-down of drug dealers, of extracting sexual favors from a female, and of minor misconduct involving an officer's suspicious acceptance of free meals at a restaurant were reviewed by 217 mid- to upper-level police managers. While 90% of the managers endorsed an undercover investigation in cases of serious misconduct, 45% also supported an undercover probe to see what might be behind an officer accepting free meals. Endorsing an undercover probe for minor misconduct was associated with a police manager's Machiavellian and Bureaucratic attitudes, and was unrelated to familiarity with IA or criminal undercover investigations. Preemptive undercover inquiries to identify problem officers could reduce corruption in an organization, but the present study suggests that the absence of guidelines for establishing when these probes are unacceptable may lead some dedicated IA investigators to stretch the legal and ethical envelopes, and risk going too far with undercover stings. © 1998 John Wiley & Sons, Ltd.
