Psychological Contracts and Their Implications for Job Outcomes: A Social Exchange View

This article explores the relationship between on the 1 hand psychological contract fulfilment and affective commitment and on the other hand, normative commitment and job satisfaction. We hypothesized that the perceived supervisor support (PSS) and the perceived organizational support (POS) mediate the relationship between the fulfilment of the psychological contract, commitment and job satisfaction. The sample consists in 337 soldiers in training. In order to test our model, we used 3 measures of psychological contract fulfilment (economic, socioemotional and developmental), PSS and POS measures as well as attitudes. Results show that the developmental psychological contract is related to affective and normative organizational commitment and job satisfaction whereas socioemotional fulfilment is unrelated to affective commitment. Psychological contract fulfilment has a greater impact on normative commitment than affective commitment. Results show also that only PSS plays a mediating role in psychological contract processes. Several implications emerge from this study. First, in a military context, it is important to strengthen the developmental psychological contract. Second, it is essential for organizations to place greater emphasis on encouraging supervisors to establish healthy working relationships with newcomers.     

Visual discrimination of species in dogs (Canis familiaris)

In most social interactions, an animal has to determine whether the other animal belongs to its own species. This perception may be visual and may involve several cognitive processes such as discrimination and categorization. Perceptual categorization is likely to be involved in species characterized by a great phenotypic diversity. As a consequence of intensive artificial selection, domestic dogs, Canis familiaris, present the largest phenotypic diversity among domestic mammals. The goal of our study was to determine whether dogs can discriminate any type of dog from other species and can group all dogs whatever their phenotypes within the same category. Nine pet dogs were successfully trained through instrumental conditioning using a clicker and food rewards to choose a rewarded image, S+, out of two images displayed on computer screens. The generalization step consisted in the presentation of a large sample of paired images of heads of dogs from different breeds and cross-breeds with those of other mammal species, included humans. A reversal phase followed the generalization step. Each of the nine subjects was able to group all the images of dogs within the same category. Thus, the dogs have the capacity of species discrimination despite their great phenotypic variability, based only on visual images of heads.     

Le risque médico-judiciaire des infections nosocomiales

These last years in France, the term ‘nosocomial infection’ has been replaced by ‘health-care associated infection’, which has a much broader definition. In all cases, the plausibility of the association between infection and the care provided deserved to be rigorously analyzed. To qualify an infection as nosocomial, the expert witness must at the judge's request determine that infection actually occurred within the health facility and is linked to health care. French Public Health Code as well the most recent jurisprudence give currently a rather close definition of nosocomial infection. The principle of faultness liability in the field of nosocomial infection has been enshrined in the law of March 4^th 2002, the most severe situations (death; permanent functional deficit > 25 percent) being compensated by ONIAM, the French national office of compensation for nosocomial infection.     

Affective dimensions of odor perception: a comparison between Swiss, British, and Singaporean populations

Do affective responses to odors vary as a function of culture? To address this question, we developed two self-report scales in the United Kingdom (Liverpool: LEOS) and in Singapore (city of Singapore: SEOS), following the same procedure as used in the past to develop the Geneva Emotion and Odor Scale (GEOS: Chrea, Grandjean, Delplanque et al., 2009). The final scales were obtained by a three-step reduction of an initial pool of 480 affective terms, retaining only the most relevant terms to describe odor-related subjective affective states and comprised of six (GEOS) or seven affective dimensions (LEOS and SEOS). These included dimensions that were common to the three cultures (Disgust, Happiness Well-being, Sensuality Desire, and Energy), common to the two European samples (Soothing Peacefulness), and dimensions that were culture specific (Sensory Pleasure in Geneva; Nostalgia and Hunger Thirst in Liverpool; Intellectual Stimulation, Spirituality, and Negative Feelings in Singapore). A comparative approach showed that the dimensional organization of odor-related affective terms in a given culture better explained data variability for that culture than data variability for the other cultures, thus highlighting the importance of culture-specific tools in the investigation of odor-related affect.     

Contemporary theories of 1/f noise in motor control

1/f noise has been discovered in a number of time series collected in psychological and behavioral experiments. This ubiquitous phenomenon has been ignored for a long time and classical models were not designed for accounting for these long-range correlations. The aim of this paper is to present and discuss contrasted theoretical perspectives on 1/f noise, in order to provide a comprehensive overview of current debates in this domain. In a first part, we propose a formal definition of the phenomenon of 1/f noise, and we present some commonly used methods for measuring long-range correlations in time series. In a second part, we develop a theoretical position that considers 1/f noise as the hallmark of system complexity. From this point of view, 1/f noise emerges from the coordination of the many elements that compose the system. In a third part, we present a theoretical counterpoint suggesting that 1/f noise could emerge from localized sources within the system. In conclusion, we try to draw some lines of reasoning for going beyond the opposition between these two approaches.     

Being Successful in a Creative Profession: The Role of Innovative Cognitive Style, Self-Regulation, and Self-Efficacy

Purpose  

The purpose of this study was to test a model that proposes that innovative cognitive style and self-regulation (setting priorities, planning work activities, and monitoring time and task progress) are related to the self-reported success of architects. We investigated two aspects of the success: as designers and as business people. To this end, we examined the mediating role of self-efficacy in these relationships.     

Biased extensive measurement: The general case

We develop a theory of biased extensive measurement which allows us to prove the existence of a ratio-scale without transitivity of indifference and with a property of homothetic invariance weaker than independence. These representations, which cover the cases of interval orders and of semiorders, reveal a unique biasing function smaller or equal to 1 that distorts extensive measurement and explains departures from its standard axioms. We interpret this biasing function as characterizing the qualitative influence of the underlying measurement process and we show that it induces a proportional indifference threshold.     

The role of head-centric spatial reference with a static and kinetic visual disturbance

A static or kinetic visual disturbance affects subjects’ ability to estimate the direction of the gravitational vertical. This kind of error is increased by a head roll inclination. In two experiments, we combined head orientation with a static (Experiment 1: tilted frame) versus kinetic (Experiment 2: rotating disk) visual disturbance. The results showed that with a static visual disturbance, the increase of errors in the inclined head condition was mainly the consequence of a postural head effect like an Aubert effect. On the contrary, with a kinetic visual disturbance, it appears that the disk effect increases with head inclination. However, individual errors observed with the head inclined in front of a stationary disk were systematically correlated with the errors triggered by the same head inclination in front of a rotating disk. These observations confirm that the head axis spatial reference plays an important role in orientation perception, whatever the head position and the kind of visual display.
