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These last years in France, the term ‘nosocomial infection’ has been replaced by ‘health-care associated infection’, which has a much broader definition.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.     

Outcome evaluation in brief mother-infant psychotherapies: Report on 75 cases

The effects of brief mother–infant psychotherapies (maximum of 10 sessions) were examined in cases of functional and behavioral disturbances in children less than 30 months old. Seventy-five mother-infant dyads were assessed prior to treatment, at 1 week, and 6 months after therapy ended. The outcome measures were changes in the infant's symptoms, the behavioral interactions between mother and infant, and maternal representations. The effect of two forms of intervention—Psychodynamic Therapy and Interaction Guidance Therapy—were compared. Results indicated a significant symptom reduction; dyadic interactions became more harmonious (mothers became less intrusive and infants more cooperative). Maternal self-esteem grew significantly and negative affects decreased. Improvements lasted as least several months, with some positive improvement detected at the 6-month follow-up. No major difference in outcome was found between the effects of the two forms of intervention. Within the limitations of research in a clinical context, this study suggests that brief mother–infant psychotherapies are a cost-effective method of early intervention.     

Parafoveal letter-position coding in reading

The masked-priming lexical decision task has been the paradigm of choice for investigating how readers code for letter identity and position. Insight into the temporal integration of information between prime and target words has pointed out, among other things, that readers do not code for the absolute position of letters. This conception has spurred various accounts of the word recognition process, but the results at present do not favor one account in particular. Thus, employing a new strategy, the present study moves out of the arena of temporal- and into the arena of spatial information integration. We present two lexical decision experiments that tested how the processing of six-letter target words is influenced by simultaneously presented flanking stimuli (each stimulus was presented for 150 ms). We manipulated the orthographic relatedness between the targets and flankers, in terms of both letter identity (same/different letters based on the target’s outer/inner letters) and letter position (intact/reversed order of letters and of flankers, contiguous/noncontiguous flankers). Target processing was strongly facilitated by same-letter flankers, and this facilitatory effect was modulated by both letter/flanker order and contiguity. However, when the flankers consisted of the target’s inner-positioned letters alone, letter order no longer mattered. These findings suggest that readers may code for the relative position of letters using words’ edges as spatial points of reference. We conclude that the flanker paradigm provides a fruitful means to investigate letter-position coding in the fovea and parafovea.     

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.     

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.
