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.     

High test-retest reliability of a neural index of rapid automatic discrimination of unfamiliar individual faces

An important aspect of human individual face recognition is the ability to discriminate unfamiliar individual. Since many general processes contribute to explicit behavioural performance in individual face discrimination tasks, isolating a measure of unfamiliar individual face discrimination ability in humans is challenging. In recent years, a fast periodic visual stimulation approach (FPVS) has provided objective (frequency-locked) implicit electrophysiological indices of individual face discrimination that are highly sensitive at the individual level within a few minutes of testing. Here we evaluate the test-retest reliability of this response across scalp electroencephalographic (EEG) recording sessions separated by more than two months, in the same 30 individuals. We found no test-retest difference overall across sessions in terms of amplitude and spatial distribution of the EEG individual face discrimination response. Moreover, with only 4 stimulation sequences corresponding to 4 min of recordings per session, the individual face discrimination response was highly reliable in terms of amplitude, spatial distribution, and shape. Together with previous observations, these results strengthen the diagnostic value of FPVS-EEG as an objective and rapid flag for specific difficulties at individual face recognition in the human population.     

Neurocounseling: Promoting Human Growth and Development Throughout the Life Span

Professional counselors must understand both psychological and neurological factors that impact human development across the life span. Despite an emerging body of literature about neurocounseling, little is known about how to integrate this information into supervision or the counseling curriculum. This article provides an overview of neuroscience topics applicable to professional counselors and recommendations for learning about neurocounseling.     

Toward a Life Course Framework for Studying Vulnerability

Interest in the study of vulnerability has experienced impressive growth across various disciplines. To contribute to this major but scattered development in the study of vulnerability, this article argues for a multidisciplinary life-course framework. This framework promotes a systemic and dynamic perspective focused on three complementary research directions: multidimensional, multilevel, and multidirectional. On the basis of this life course perspective, the authors also propose a definition of vulnerability as a dynamic process of stress and resources across various domains of life (i.e., work, family, health, migration, etc.), levels (i.e., person, group, collective), and time (i.e., long-term processes).     

Analogous selection processes in declarative and procedural working memory: N-2 list-repetition and task-repetition costs

Working memory (WM) holds and manipulates representations for ongoing cognition. Oberauer (Psychology of Learning and Motivation, 51, 45–100, 2009) distinguishes between two analogous WM sub-systems: a declarative WM which handles the objects of thought, and a procedural WM which handles the representations of (cognitive) actions. Here, we assessed whether analogous effects are observed when participants switch between memory sets (declarative representations) and when they switch between task sets (procedural representations). One mechanism assumed to facilitate switching in procedural WM is the inhibition of previously used, but currently irrelevant task sets, as indexed by n-2 task-repetition costs (Mayr & Keele, Journal of Experimental Psychology: General, 129(1), 4–26, 2000). In this study we tested for an analogous effect in declarative WM. We assessed the evidence for n-2 list-repetition costs across eight experiments in which participants switched between memory lists to perform speeded classifications, mental arithmetic, or a local recognition test. N-2 list-repetition costs were obtained consistently in conditions assumed to increase interference between memory lists, and when lists formed chunks in long-term memory. Further analyses across experiments revealed a substantial contribution of episodic memory to n-2 list-repetition costs, thereby questioning the interpretation of n-2 repetition costs as reflecting inhibition. We reanalyzed the data of eight task-switching experiments, and observed that episodic memory also contributes to n-2 task-repetition costs. Taken together, these results show analogous processing principles in declarative and procedural WM, and question the relevance of inhibitory processes for efficient switching between mental sets.
