Développer un système de gestion de la sécurité et augmenter la culture de sécurité en milieu hospitalier sont des objectifs essentiels dans des systèmes complexes et dynamiques. Après avoir passé en revue les mécanismes et la prévention des événements indésirables, nous proposons une réflexion sur une approche complémentaire pour le choix d’un outil capable de s’intégrer dans le quotidien des soins. Dans un esprit Safety-II, l’effort se porte vers une élévation des connaissances mais aussi des compétences pour que les tâches et donc les processus soient exécutés avec facilité et sans erreur.

ABSTRACT This study aimed to examine the directionality of the relationship between event justice and social entity justice. Using two samples and a cross-lagged panel analysis with two measurement times, social entity justice was found to predict event justice (procedural, distributive, interpersonal and informational justice event), supporting the top-down process. PRESS PARAGRAPH The life of organizations is punctuated by a wide range of managerial decisions (e.g., hiring, performance appraisal or organizational change). Facing such events, employees evaluate the fairness of the situation experienced. However, little is known about how employees develop justice judgments. This study shows that employees’ fairness perceptions about their organization influence their interpretation of the fairness of subsequent events involving the organization. Building and fostering a climate of justice is therefore of primary importance for organizations, since global fairness perceptions about the organization may help employees to perceive a specific event, such as a managerial decision, as being fair.

This paper proposes an algorithm for the numerical simulation of linear structural dynamics problems under unilateral elastic constraints, i.e., constraints with a linear force/displacement characteristic whenever active. The presented procedure relies on an event-driven strategy for the handling of the contact constraints, in combination with one-step schemes dedicated to the time integration of the second-order equations of motion. Efficiency of the procedure follows from the use of cubic Hermite interpolation to continuously extend the normal gap functions that reflect the openings of the contact interfaces. Robustness follows from the proper handling of complex numerical situations, e.g., numerical grazing or discontinuity sticking, through appropriate algorithm structure and numerical implementation. And, integration stability is guaranteed by the very nature of the algorithm and that of the one-step integration scheme. Following a detailed coverage of the integration procedure and the countermeasures to the expected numerical difficulties, three application examples are treated for illustration purposes. A MATLAB implementation of the procedure is provided online; download and usage information are given in the Appendix. [less ▲]

Since the discovery of the P300 component, a large number of studies have been conducted with the aim to find abnormalities of this psychophysiological marker among the main psychiatric disorders. The first studies were very promising, but successive findings were rather controversial resulting in two main positions (the pros and the cons) as regard to the usefulness of P300 in clinical psychopathology. However, P300 studies provide interesting findings concerning information processing in psychopathology. Moreover, other Event-Related Potentials (ERPs), such as the Mismatch Negativity (MMN) and the Error-Related Negativity (ERN) are particularly interesting for the study of cognitive processes in psychopathology. In this review, the author will give an overview of the main findings of P300, MMN and ERN values in psychopathology from a clinical and a cognitive point of view. After a brief description of the rationale of ERPs, the findings in schizophrenia, depression, alcoholism, posttraumatic stress disorder, panic disorder, and obsessive-compulsive disorder will be sequentially reviewed. The diagnostic usefulness of P300 in psychopathology is limited, but could be increased if variables known to influence P300 amplitude or latency are controlled. Doubtless, grouping two or more different ERP components would greatly improve the usefulness of the clinical applications of brain potentials. On the other hand, a growing number of studies have provided evidence of the relevance of ERPs to investigate cognitive processes in psychopathology. [less ▲]

Several studies have demonstrated that the emotional value of stimuli affects P300 amplitude. In the present study, the influence of alcohol-related stimuli in alcoholic patients was investigated. Subjects were 10 alcoholic inpatients (3 female) and 10 age- and sex-matched controls. Eight alcohol-related and 8 neutral words served as stimuli in a visual oddball paradigm. Acohol-related words were targets (48 stimuli, 33%) and neutral words were standard stimuli (96 stimuli, 66%). Results showed that P300 amplitude for targets did not differ significantly between the two groups. However, P300 latency for targets as well as reaction time were significantly shorter in male alcoholic patients. In contrast, P300 latency was increased in female alcoholic patients but reaction time did not differ. These results suggest that male alcoholics process information linked to alcohol cues more rapidly than neutral cues, probably because a specific semantic network is activated in these patients. The decreased reaction time confirms the impulsive behavior frequently found in male alcoholism, as it has been described in type II alcoholism. Besides, the results imply that information processing was delayed in female alcoholic patients. Therefore this study demonstrates a gender-dependent impact of alcohol-related stimuli on information processing. [less ▲]

We consider an exponentially stable closed loop interconnection of a continuous linear plant and a continuous linear controller, and we study the problem of interconnecting the plant output to the controller input through a digital channel. We propose a family of "transmission-lazy" sensors whose goal is to transmit the measured plant output information as little as possible while preserving closed-loop stability. In particular, we propose two transmission policies, providing conditions on the transmission parameters. These guarantee global asymptotic stability when the plant state is available or when an estimate of the state is available (provided by a classical continuous linear observer). Moreover, under a specific condition, they guarantee global exponential stability [less ▲]

Welcome to the “desert of the markets”, where businesses are playthings for bigger forces! The goal of this book is to share with you what we observed on the markets over the last twenty years, and what we believe to have learned as to their behavior. The end-product is a set of several hundred “experience-filtered” thoughts, facts and rules whose any subset could provide a reasonable basis on which to build your own theory of investing. Painful and solitary work. But, your survival on the markets is at that price. In its current 2017 edition, “Ever invested. Ever Failed. No matter. Invest again. Invest better.” is organized into seven chapters: The Great Recession of 2008; Businesses, assets and liabilities; Assessing market response; Financial engineering tricks and traps; Investors, swindlers and thieves; Rules for asset protection; Investing under non-parametric uncertainty. It concludes with a discussion of A few common myths and some Final thoughts on the art and science of investing. Each chapter comprises a short introduction, followed by an extensive, and unordered, list of thoughts, facts and rules that should help you articulate your information, decision and reward systems.

BACKGROUND: Disease progression in patients with HER2-positive breast cancer receiving trastuzumab might be associated with activation of the PI3K/Akt/mTOR intracellular signalling pathway. We aimed to assess whether the addition of the mTOR inhibitor everolimus to trastuzumab might restore sensitivity to trastuzumab. METHODS: In this randomised, double-blind, placebo-controlled, phase 3 trial, we recruited women with HER2-positive, trastuzumab-resistant, advanced breast carcinoma who had previously received taxane therapy. Eligible patients were randomly assigned (1:1) using a central patient screening and randomisation system to daily everolimus (5 mg/day) plus weekly trastuzumab (2 mg/kg) and vinorelbine (25 mg/m2) or to placebo plus trastuzumab plus vinorelbine, in 3-week cycles, stratified by previous lapatinib use. The primary endpoint was progression-free survival (PFS) by local assessment in the intention-to-treat population. We report the final analysis for PFS; overall survival follow-up is still in progress. This trial is registered with ClinicalTrials.gov, number NCT01007942. FINDINGS: Between Oct 26, 2009, and May 23, 2012, 569 patients were randomly assigned to everolimus (n=284) or placebo (n=285). Median follow-up at the time of analysis was 20.2 months (IQR 15.0-27.1). Median PFS was 7.00 months (95% CI 6.74-8.18) with everolimus and 5.78 months (5.49-6.90) with placebo (hazard ratio 0.78 [95% CI 0.65-0.95]; p=0.0067). The most common grade 3-4 adverse events were neutropenia (204 [73%] of 280 patients in the everolimus group vs 175 [62%] of 282 patients in the placebo group), leucopenia (106 [38%] vs 82 [29%]), anaemia (53 [19%] vs 17 [6%]), febrile neutropenia (44 [16%] vs ten [4%]), stomatitis (37 [13%] vs four [1%]), and fatigue (34 [12%] vs 11 [4%]). Serious adverse events were reported in 117 (42%) patients in the everolimus group and 55 (20%) in the placebo group; two on-treatment deaths due to adverse events occurred in each group. INTERPRETATION: The addition of everolimus to trastuzumab plus vinorelbine significantly prolongs PFS in patients with trastuzumab-resistant and taxane-pretreated, HER2-positive, advanced breast cancer. The clinical benefit should be considered in the context of the adverse event profile in this population. FUNDING: Novartis Pharmaceuticals Corporation. [less ▲]

Item response theory (IRT) is not only a famous acronym, it also covers a broad range of statistical and psychometric models, methods, and applications in psychology and educational science. However, IRT looks somewhat misunderstood or even esoteric to the non-statisticians and non-psychometricians. The main goal of this talk is to briefly and clearly present the main aspects of traditional IRT: objectives, assumptions, basic models, and basic estimation methods. As a secondary purpose, extensions of IRT to more complex situations (polytomous data, multidimensional and hierarchical models, computerized adaptive testing, differential item functioning, nonparametric IRT) are briefly outlined. This talk will be as little technical as possible, focusing on the main concepts and applications of this theory. [less ▲]

The purpose of this paper is to introduce an innovative instrument for policies aiming at energy savings in the household sector. This new instrument, which is based on the innovative coupling of complementary currencies and smart metering, has been designed to take into account insights gained from transition theory regarding barriers to change. However, could this new instrument also be designed to translate into policy-making some of the insights gained from social practices theory about everyday life energy consumption in the household? What about the use of complementary currencies, which is very innovative regarding policy-making in the field of energy saving? What insights does the use of Convention Theory provide to this respect? Accordingly, after a short introduction, the second section of this paper is dedicated to the description of the instrument for energy saving policies based on the innovative coupling of complementary currencies and smart metering. The third section focuses on the most relevant insights gained from using a social practices framework in the field of everyday life energy consumption in the household sector. The fourth part is dedicated to convention theory and how it could be extended to analysing the use of complementary currencies in the new instrument. Finally, building on the insights gained from using a social practices and convention framework, the fifth and last part is dedicated to investigating to which extent the new instrument could be designed in a way to incorporate those insights, and to providing policy recommendation.
