Aim: The Psychopathy Checklist-Revised (PCL-R) is the most studied and validated instrument to measure psychopathy. We aimed to explore its items content invariance to forensic schizophrenic subjects. Method: We examined the PCL-R protocol of 15 male forensic schizophrenic subjects and attributed a score of sensitivity to psychotic symptomatology to each item score. Results: Results suggest that the applicability of the PCL-R items to a forensic schizophrenic sample is not to be blindly warranted. Some items more systematically positively influenced by psychotic symptoms (e.g. Shallow Affect, Lack of Remorse or Guilt), while others were negatively influenced (e.g. Promiscuous Sexual Behavior, Glib and Superficial Charm), or not influenced at all (e.g. Criminal Versatility). Conclusions: The current study suggest that the applicability of the PCL-R items to a forensic schizophrenic sample is not to be blindly warranted. We discuss both psychometric and conceptual implications for the measurement of psychopathy when a diagnosis of schizophrenia has been established. [less ▲]

The paper describes the factors influencing the interplay of pension and tax policies from a fiscal and welfare perspective, and identifies areas where both topics can materially impact one another. The paper also explores the arguments for coordination between income tax and pension policies in light of the distributional and behavioral synergies. The paper raises questions regarding tax policy’s effectiveness for materially influencing pension coverage, contribution compliance, and labor mobility. The authors argue for taxing pension similarly to all other incomes and for limiting tax treatment of mandatory pensions, and for initiating coordinated tax and pension reforms before electoral demographics render such reforms even more difficult than today.

Introduction: Given that recent research has shown that functional connectivity is not a static phenomenon, we aim to investigate the dynamic properties of the default mode network’s (DMN) connectivity in patients with disorders of consciousness. Methods: Resting-state fMRI volumes of a convenience sample of 17 patients in unresponsive wakefulness syndrome (UWS) and controls were reduced to a spatiotemporal point process by selecting critical time points in the posterior cingulate cortex (PCC). Spatial clustering was performed on the extracted PCC time frames to obtain 8 different co-activation patterns (CAPs). We investigated spatial connectivity patterns positively and negatively correlated with PCC using both CAPs and standard stationary method. We calculated CAPs occurrences and the total number of frames. Results: Compared to controls, patients showed (i) decreased within-network positive correlations and between-network negative correlations, (ii) emergence of “pathological” within-network negative correlations and between-network positive correlations (better defined with CAPs), and (iii) “pathological” increases in within-network positive correlations and between-network negative correlations (only detectable using CAPs). Patients showed decreased occurrence of DMN-like CAPs (1–2) compared to controls. No between-group differences were observed in the total number of frames Conclusion: CAPs reveal at a more fine-grained level the multifaceted spatial connectivity reconfiguration following the DMN disruption in UWS patients, which is more complex than previously thought and suggests alternative anatomical substrates for consciousness. BOLD fluctuations do not seem to differ between patients and controls, suggesting that BOLD response represents an intrinsic feature of the signal, and therefore that spatial configuration is more important for consciousness than BOLD activation itself.

Worldwide, flood risk is expected to increase over the 21st century due to the combined effect of climate and land use changes. However, while the impact of climate change on future flood risk was extensively studied, the effects of urbanization remain unclear. The goal of this PhD thesis is to contribute to a better understanding of the influence of future urban development on changes in inundation flows as well as on the related damage. First, an original porosity-based model was developed, which enables efficient computation of urban flooding. It uses anisotropic porosity parameters to reproduce the influence of subgrid-scale obstacles on the flow. An original merging technique was implemented to optimize the computational efficiency in the presence of low values of the storage porosity parameter. Compared to a standard inundation model, the developed model enables speedup factors of the order of 100, while keeping the error on the flow variables at a few percent. Second, we systematically investigated how the layout of buildings located in floodplains influences the inundation characteristics for a long-duration flood scenario. The anisotropic porosity-based model was used to compute the flow variables for 2,000 alternative urban patterns. Correlations between the computed water depths and the urban characteristics reveal which features of the layout of buildings influences most the severity of urban flooding. In particular, the results suggest how the hydraulic effect of new urban development can be effectively mitigated by a suitable location of the buildings preserving a higher flow conveyance at the district-scale. This result provides guidance for more flood-proof urban developments. Finally, we evaluated the evolution of future flood damage as a result of urbanization along all the main rivers in the Walloon region, Belgium. The study was conducted at the regional level using detailed hydraulic results (resolution of 2 to 5 m). Despite high uncertainties in the considered urbanization scenarios, involving both urban expansion and densification, robust conclusions could be drawn, such as the overwhelming influence of banning new developments in flood-prone areas compared to the other tested facets of urban planning policy.

In this work, materials have been produced by sol-gel route. This synthesis way has been used for immobilization on a support of a function focused on green chemistry. The different functions are related with different applications that allow to illustrate the versatility and the flexibility of this sol-gel process. The two applications are: - Photocatalysis: Synthesis of material with photocatalytic property or with an additional property - Cyclocarbonation: Synthesis of an immobilized catalyst for polyurethane production through a green process The first application concerns the use of a photocatalyst that allows to degrade volatile organic compounds (VOC). The main photocatalyst is TiO2. It has been studied as a powder or as a film deposited on a support. A comparison of these two shapes has shown that an identical photocatalyst can have different performances depending on the final shape. A catalyst must be considered in its totality and with its environment rather than as a chemical composition only. To increase the photocatalyst performances, modifications have been added as the Zn doping to increase the photocatalytic activity and the superhydrophilicity. These new photocatalysts have been compared with pure ZnO and bilayer films composed of TiO2 and of ZnO. Different photocatalytic tests have been performed and depending on the test the best photocatalyst was different. Then, to increase the economic interest, some dopant have been used. In addition of the improvement of the photocatalytic activity and superhydrophilicity, theses dopants add a new property such as electrical conductivity and anticorrosion. First, metallic silver has been incorporated to add antistatic property and to increase the photocatalytic activity. The photocatalytic property has been improved, superhydrophilicity has been kept but no antistatic property was observed. Multiwall carbon nanotubes (MWCNTs) have been tested with TiO2 to increase the electrical conductivity. This doping is efficient because MWCNTs increase the conductivity, the photocatalytic activity and maintain the superhydrophilicity. In addition, anticorrosive property has been observed on stainless steel in a preliminary study with the MWCNTs incorporation. The second study is focused on the heterogeneous cyclocarbonation catalyst synthesis to produce, in fine, polyurethane. The catalyst was immobilized on different matrices that are inert from catalytic point of view but that have a potential activator effect. First, with the preselected catalyst, different supports have been investigated. The comparison between the supports has highlighted the activator effect and the texture influence (accessibility of the active sites) on cyclocarbonation yields. Then, with the optimal matrix, different catalysts from a same family have been grafted to choose the best catalyst. Therefore, it has been possible to define the best catalyst and the best support. With this combination, a kinetic study has been performed to determine the best experimental conditions to produce cyclocarbonates. [less ▲]

The psychometric properties of the French version of the Child Short Form of the Trait Emotional Intelligence Questionnaire (TEIQue-CSF) were investigated in a sample of 556 from 9 to 13 years old. The internal consistency and temporal stability were satisfactory. A significant difference for gender, but not for age, was observed. With regard to the factor structure, the best fit was found for a two-factor solution, emotion control and socioemotionality. Regarding convergent validity, positive correlations were found with the total and all except one-factor scores of the Emotion Awareness Questionnaire score (EAQ30). Evidences of concurrent validity were demonstrated, with negative correlations with State-Trait Anxiety Inventory for Children (STAIC) and Childhood Anxiety Sensitivity Index (CASI). Results also showed a positive correlation with Children’s Social Desirability Scale (CSD). In conclusion, these findings provide additional support for the use of the TEIQue-CSF for researchers and practitioners who want to assess emotion-related constructs in children. [less ▲]

BACKROUND: Emergency Medical Services (EMS) routinely work at the very limit of their capacity due to growing emergency rooms visits and residents’ shortage. In this context, EMS workers are regularly asked to work more than 10 hours a day, on varying shifts and with short recuperation breaks. Two approaches can be used to reduce fatigue-related risk: reducing the likelihood a fatigued operator is working (i.e. fatigue reduction), or reducing the likelihood a fatigued operator will make an error (i.e. fatigue proofing). In Emergency Medical Services, formal risk control mainly focuses on reduction strategies such as reducing work hours while proofing strategies develops as an implicit element of the safety system. OBJECTIVE: Our purpose is to identify individual proofing and reduction strategies used by emergency residents and to investigate how they relate to fatigue, performance and patient safety indicators. METHODS: First, we conducted 4 focus-group sessions with a total of 25 EMS residents to elicit perceived consequences of fatigue and strategies used to cope with them. Focus group results were used to design a questionnaire assessing how often EMS residents personally used any of the strategies reported during sessions. Second, we administered the questionnaire to a larger sample and conducted a prospective observational study with a repeated within-subjects component. A total of 45 EMS residents participated in the study for a total of 400 shifts analyzed. We gathered sleep diaries, subjective sleepiness, reaction time, self-reported medical errors and performance ratings at different time point during both day and night shift using an android-based application. Sleep time and activity levels were confirmed using wrist actigraphy. DISCUSSION: We will discuss what can be drawn from our results in terms of individual and collective resilience processes with a focus on the potential for implementation of more formal processes at a system level.  [less ▲]

Anycast offers a method for making a service IP address available to a routing system from several locations at once. It is used today to provide important services, such as naming and content delivery, in an economic, scalable, and simple to operate manner. The appeal and clear benefits of anycast to service providers have motivated a number of recent experimental studies on its potential performance impact. All studies have, to the best of our knowledge, focused on wired networks, despite the growing dominance of mobile as the most common and sometimes only form of Internet access. In this thesis, we present the first study of anycast performance for mobile users. In particular, our evaluation focuses on three distinct anycast services: K- and F-Root, each providing part the DNS root zone, and Google DNS. Our research revolves around three axes. First, we show that mobile clients are frequently routed to suboptimal replicas in terms of latency and that this issue is not limited to specific regions or ASes of the world. Second, we find that clients are often redirected to a DNS server hosted very far away from her. This happens more frequently while on a cellular connection than on WiFi, with a significant impact on performance. Our study reveals that this is not simply an issue of not having better alternatives, and that the problem is not localised to particular geographic areas or particular ASes. We investigate root causes of this phenomenon and describe three of the major detected classes of anycast anomalies. Third and finally, we explore IP assignment dynamics of mobile clients and find that recurrent IP changes on the client side lead to significant perceived variations of anycast latency. [less ▲]

The occurrence of an unexpected death puts the witnesses of this event in a situation of high emotional impact. The benefit to allow the families of victims to dispense the first resuscitation techniques has been emphasized. However, little data exist on the emotional impact of a cardio-respiratory arrest outside the hospital on the witness, who is often a close family member. Recently, we investigated the presence of psychological distress and the factors influencing it, in the active practice of basic resuscitation gestures by the witnesses guided by the operator 112. Resuscitation by a person not belonging to the medical corps seems not to be devoid of impact. Indeed, the presence of psychological distress is observed for most of witnesses questioned 6 to 10 days after the call but also 3 months later. This work highlights therefore the importance of identifying the coping strategies involved, in order to promote potentially beneficial strategies and limit the trauma associated with this type of event.
