Actions Pour l’intégration Socioprofessionnelle Des Travailleurs Issus De L’immigration: La Valorisation Identitaire Comme Mode d’Accompagnement Spécifique

In industrialized countries, economic problems linked to the changing world and working habits potentially impact all workers; however, immigrant workers experience additional difficulties owing to their status as foreigners or as people of foreign origin. While these employment obstacles are varied, the problems are not absolute and do not affect all foreign job seekers with the same intensity. Moreover, various attitudes can be effective when faced with certain obstacles. We call them “bypassing strategies”: the behaviour of foreign job seekers trying to negotiate these obstacles. This article presents and discusses several cases of adult training and job seeker support initiatives from French-speaking Belgium; within a specific context, these experiences are based on the concept of “professional and identity development” of immigrant workers.     

Comparing associative, statistical, and inferential reasoning accounts of human contingency learning

For more than two decades, researchers have contrasted the relative merits of associative and statistical theories as accounts of human contingency learning. This debate, still far from resolution, has led to further refinement of models within each family of theories. More recently, a third theoretical view has joined the debate: the inferential reasoning account. The explanations of these three accounts differ critically in many aspects, such as level of analysis and their emphasis on different steps within the information-processing sequence. Also, each account has important advantages (as well as critical flaws) and emphasizes experimental evidence that poses problems to the others. Some hybrid models of human contingency learning have attempted to reconcile certain features of these accounts, thereby benefiting from some of the unique advantages of different families of accounts. A comparison of these families of accounts will help us appreciate the challenges that research on human contingency learning will face over the coming years.     

Relating reference points and weights in MOLP

A frequent problem for decision makers (DMs) analysing decisions involving multiple objectives is the identification and selection of the most preferred option from the set of non‐dominated solutions. Two techniques, weighted sum optimization and reference point optimization, have been developed to address this problem for multiobjective linear programming problems (MOLP). In this paper, we examine the relationship between these two techniques. We demonstrate that the values of the dual variables associate with auxiliary constraints of the reference point technique are equal to the weight values used to compute the same non‐dominated solution via the weighted sum technique. This insight will enable the development of new interactive solution procedures for MOLPs which allow the DM to readily switch from one method to the other during the search for the most preferred non‐dominated solution. The advantages of the approach are discussed in the paper. Copyright © 1999 John Wiley & Sons, Ltd.     

Efficiency and accuracy of visual search develop at different rates from early childhood through early adulthood

Psychonomic Bulletin & Review - Most studies of visual search across the life span have focused on classic feature and conjunction searches in which observers search for a fixed, simple shape...     

Oceans of stimuli: an individual-based model to assess the role of olfactory cues and local enhancement in seabirds’ foraging behaviour

Animal Cognition - Oceans are extremely dynamic environments, which poses challenges for top-predators such as seabirds to find food resources. Yet, seabirds evolved sensorial abilities (olfactory...     

Acquisition and maintenance of delayed matching-to-sample in tufted capuchin monkeys

Delayed matching-to-sample (DMTS) is a commonly used procedure to investigate short-term memory. For the study of functions of forgetting, the delay between the disappearance of the sample stimulus and appearance of choices is manipulated. The intertrial interval (ITI) is also varied to assess interference effects. Performance decrements have been observed as delay increases and, in some cases, performance recovery occurs when ITIs are increased. Other studies indicate that the higher the ITI/delay ratio, the greater the accuracy in DMTS. In this study, 2 experiments investigated DMTS performances of 3 tufted capuchin monkeys as function of delay and ITI. In Experiment 1, alternation of gradual increases of delay and ITI was effective in producing ≥90% accuracy at delays as long as 90 s. Individual monkeys differed in the highest value of delay at which this criterion was met. In Experiment 2, the monkeys were exposed to 5-s DMTS with different ITIs to assess the effects of various ITI/delay ratios on accuracy. Highest accuracy tended to occur at the higher ITI/delay ratios.     

Psychometric Properties of the Objectified Body Consciousness Scale (OBCS) in Spanish Preadolescents

Sex Roles - Objectification theory postulates that the body is constructed as a sexual object and is subject to observation and evaluation in such a way that a person may feel that their body is an...     

W. I. Thomas and social reform: His work and writings

W. I. Thomas was a major figure in the founding of sociology, especially symbolic interactionism. His concern with and commitment to social reform, however, is rarely recognized. This neglected aspect of his thought and activities is crucial for the interpretation and assessment of his writings and status in the profession. Examination of this facet of his work also illuminates some of the important contributions made by women to the development of his thought and career.     

Developing and Validating the Perceived Parental Media Mediation Scale: A Self‐Determination Perspective

The aim of this study was to develop the Perceived Parental Media Mediation Scale (PPMMS). The PPMMS measures adolescents' perceptions about how frequently their parents restrict or actively discuss their media use, and in what style (i.e., autonomy‐supportive, controlling, or inconsistent). In a first study among 761 preadolescents and early adolescents (10–14 years), we confirmed that the subscales of the PPMMS could be distinguished. In a second study, in which 499 adolescents were surveyed again, the test–retest reliability and validity of the PPMMS were established. The PPMMS met the standards of reliability, validity, and utility. Subscales correlated in the expected directions with general parenting styles, family conflict, prosocial behavior, and antisocial behavior.
