Introduction: The Dropout phenomenon has been studied extensively in general psychotherapy and in more specific domains. Therapeutic programs for male batterers across Europe, United States or Canada also have their share of problems in their attempts to maintain users in treatment. The purpose of this study is to identify potential intrapsychic variables associated with dropout and completion of this kind of treatment. Method: Fifty one male offenders enrolled in a group treatment for domestic violence took part in the study (23 who abandoned and 28 who completed). Before the start of therapy, they were surveyed using questionnaires and structured clinical interview to collect sociodemographic data and to assess specific psychological variables, namely emotional distress (BDI), impulsive behavior (BIS-11), early relationship with their parents (PBI), life events (LEDS) and alexithymia (TAS-20), the inability to experience and express subjective emotions. Results: Correlational analysis showed that age, paternal parenting behaviors and the number of significant events reported in the past six months are the only variables correlated with treatment dropout. The younger the participants, the most likely they were to dropout of the group therapy. Moreover, men who completed treatment reported fewer difficulties in their life and less autonomy support by their father than men who prematurely terminated their therapy. Discussion: The present findings pose a serious challenge for all actors involved in specifics treatment programs. Indeed, if all individuals who committed violent acts have the same intrapsychic variables, how do we predict, especially retain and motivate, the users likely to dropout? [less ▲]

Selon Fourouzan, Malingrey et Brouillette-Alarie (2012), la littérature scientifique évoque qu’au cours des 25 dernières années, le taux de criminalité des femmes a augmenté dans plusieurs pays. Cette augmentation de criminalité, associée à une hausse du taux d’incarcération, suscite un réel intérêt et les recherches portant sur la criminalité féminine sont actuellement plus nombreuses. La notion de psychopathie féminine y est cependant peu abordée. Le concept de psychopathie a principalement été étudié au travers de recherches se basant sur une population masculine. C’est en 1941 que H. Cleckley fournit la première description clinique de la psychopathie, dans son œuvre, « The mask of sanity » et en 1991 que R. Hare développe son échelle, la PCL-R (Psychopathy Checklist-Revised) auprès d’une population exclusivement masculine et permettant de diagnostiquer la sévérité du trouble psychopathique et le risque de criminalité violente ou non. En effet, pour Hart (1998), cité par Monhonval, Linkowski et Leistedt (2011), la psychopathie est centrale à toute évaluation du risque de violence car elle en constitue un facteur important et ne pas la considérer serait une négligence professionnelle. La psychopathie féminine constitue dès lors, une notion importante, voire centrale, dans l’évaluation de la situation des détenues en termes de réinsertion et de prédiction du risque de récidive. Dans le cadre de la présente étude portant sur des entretiens semi-structurés et évaluations psychologiques avec des femmes incarcérées au sein d’un établissement pénitentiaire belge francophone, nous présenterons une description générale du concept de psychopathie et tenterons de décrire en quoi ce type de personnalité se caractérise chez les femmes. Différentes hypothèses étiopathogéniques ont déjà été traitées pour expliquer ce trouble, et dans le cadre de notre présentation, nous allons nous centrer sur la notion d’attachement en questionnant les liens entre la psychopathie et les troubles de l’attachement .

Les recherches sur l’agression sexuelle des mineurs se sont prioritairement centrées sur l’étude des auteurs masculins alors que les filles ont été plutôt associées au statut de victime et non d’auteurs. Envisager la jeune fille comme auteure d’agression sexuelle a nécessité des avancées au niveau de la reconnaissance de la réalité des violences sexuelles perpétrées par les mineurs et de la délinquance sexuelle chez les femmes adultes. Les études menées en délinquance sexuelle estiment que les auteurs mineurs d’infraction à caractère sexuel (AAICS) de sexe féminin constitueraient entre 5% et 8% de l’ensemble des AAICS. Dès lors, si les filles sont plus souvent victimes d’abus sexuels que les garçons, elles semblent moins nombreuses que les garçons à commettre des agressions sexuelles. Les études en délinquance non sexuelle ont démontré que la victimisation sexuelle durant l’enfance est un facteur significativement associé au risque de conduites déviantes et de trajectoire délinquante durant l’adolescence, particulièrement pour les filles. Dans la continuité du questionnement mené dans le champ de recherche en délinquance non sexuelle (différences intra et inter-groupes selon les sexes en termes d’intensité, de gravité et de diversification des activités délinquantes), nous allons envisager ces questions par rapport à la délinquance sexuelle. L’analyse de de 225 dossiers judiciaires de mineurs, auteurs de faits qualifiés infraction à caractère sexuel (150 garçons et 75 filles) a permis de dégager les profils psycho-sociaux de ces mineurs, les trajectoires délinquantes et la nature des délits sexuels et confirme la thèse de l’hétérogénéité intra-groupale. Notre recherche a également porté sur les décisions prises à l’égard des AAICS par les juridictions de la jeunesse : taux de renvoi par le Ministère Public devant le Tribunal de la Jeunesse, caractéristiques spécifiques de cette population soumise à un jugement, éléments orientant la décision du juge de placer le mineur hors de son milieu de vie.

The exercise of parenthood is threatened by the precarious context in which parents and children live. Precariousness is defined by the lack or the absence of basic securities, such as housing, employment, financial, emotional security, etc. In such a context, the emotional availability of a parent can be reduced, so that the quality of parent-child interactions decreases and multiple dimensions of the child development are impacted. Therefore, policies of prevention and intervention have been developed in order to overcome the difficulties experienced by parents from birth and, sometimes, from pregnancy. However, little is known about the parenting sense of competence of mother living in such a precarious context, and the possible mediating effect of perceived social support. In this study, we investigate parenting sense of competence in a sample of 38 adult mothers raising alone their children in a context of poverty. Subjects completed the French versions of the “Parenting Sense of Competence Scale (P.S.O.C.)” and the “Social Provisions Scale”, and a socio-demographic questionnaire. Results indicate that, in average, mothers report a high parenting sense of competence (μ=69.18), characterized by a high level of self-efficacy (μ=32.76) and an average level of satisfaction (μ=36.42). Mothers also report low perceived social support (T=41, percentile 21). Results also indicate a significant negative correlate between self-efficacy and the need to feel useful and necessary, while the satisfaction dimension is positively correlated with all the perceived social support dimensions, except from the “need to feel useful” dimension. In conclusion, mothers raising alone their children in a context of poverty report high levels of parenting sense of competence. However, withdrawal and isolation are associated with poorer parental satisfaction. This suggests that the social dimension of poverty is a significant aspect to consider in parenting support policies. [less ▲]

Integration between levels of care is not facilitated by the Belgian health system. Indeed, patients have uninhibited access to every level of care, there is no gatekeeping system, and no structural coordination between levels of care. Meanwhile, on one hand, the occurrence of more complex care situations in the ambulatory setting is enhancing the need for coordination while on the other hand, hospitals face financial constraints to provide care in the community. The aim of the research was to organize coordination between levels of care at the local level, in an urban setting. We used the “Local Health System” model (LHS) that aims at integrating hospital and primary care activities for a defined population at the local level. We chose the participatory action research (PAR) methodology and its spiral plan-do-study-act cycles, to ensure the participation and implementation of results by the targeted actors (hospital and local general practitioners (GP) organizations).

BACKGROUND: Idiopathic pulmonary fibrosis (IPF) is a chronic lung disorder of unknown origin, which ultimately leads to death. Several growth factors such as IGFs (insulin-like-growth factor) and IGFBPs (insulin like growth factor binding proteins) seem to take part to the pathogenesis. We evaluated IGFs and IGFBPs in serum from patients with IPF and healthy subjects including 24 untreated IPF and 26 IPF receiving anti-fibrotic therapy and to compare them with healthy subjects. METHODS: Serum of 50 idiopathic pulmonary fibrosis and 55 healthy subjects (HS) were analysed by ELISA for IGFs and IGFBPs, TGF-beta and KL-6, the latter being tested as positive control in IPF. RESULTS: Serum levels of IGFBP-1 and IGFBP-2 and KL-6 were significantly higher in the IPF group than in the healthy subjects (p < 0.05, p < 0.001 and p < 0.0001 respectively) while the picture was inversed regarding IGFs. By contrast there was no significant difference between the groups with respect to TGF-beta. IGFBP-2 was significantly reduced in the patients with specific anti-fibrotic therapy pirfenidone and nintedanib compared to untreated patients (p < 0.05) but still significantly elevated in comparison to HS (p < 0.001). CONCLUSION: Serum IGFBP-1 and -2 are increased in idiopathic pulmonary fibrosis and IGFBP-2 may be reduced by anti-fibrosing therapy. IGFBPs may be promising biomarkers in IPF. [less ▲]

Nowadays, in newly built housings, energy losses due to the ventilation can represent up to 50 % of the total building energy consumption. As a result, heat recovery ventilation units are widely used in order to save primary energy and different control strategies for ventilation systems are investigated. For instance, demand control ventilation sounds like a promising solution to decrease the energy impact of the ventilation system in the residential sector. An accurate building model integrating the influence of ventilation (so called thermo-aeraulic building model) is necessary in order to investigate the control and the impact of the ventilation system on a yearly basis. The aim of the present paper consists in a description of a combined multi-zone airflow network model and thermal building model implemented in the Modelica language. The thermal model is a simplified dynamic model using equivalent thermal resistance and capacity. The airflow network is based on the traditional electrical circuit analogy. The model can be used for ventilation systems design, infiltration rate calculation, inside air quality calculation, energy consumption calculation, etc. The first part of the paper details the multi-zone thermal building model. The results obtained from the model are compared to experimental in situ results collected in the typical single family house test facilities. Those experimental results have been obtained in the frame of the IEA-EBC Annex 58. The second part of the paper introduces the multi-zone airflow network building model. Obtained model results are compared with the results provided by a typical multizone airflow analysis software, for a simple three zones test case. The third part of the paper describes the coupling between both thermal and airflow models. The different numerical problems encountered are described and solutions are discussed. [less ▲]

In the last few decades, promising new approaches to the study of the senses and to the body have shed new light on how people in the past experienced their lives, as much as on the ways in which knowledge about self and the world was being shaped, negotiated and transformed. Although all the senses could contribute to these discussions, scholars have predominantly focused on sight and visual cultures, leaving other potentially fruitful avenues unexplored. Touch, especially, has received little attention in historical research, where it has been reduced to a history of sexuality, leaving its other dimensions unexamined. Yet this sense, considered the defining sense of human nature, raises important questions regarding the part played by the lower senses in knowledge production, as well as in society and culture at large. Sources concerning Renaissance anatomy provide a significant lens through which to examine the part played by touch in the early modern study of Nature, as evidenced by the practice of dissections, which engaged the body, the skin and the hand of the anatomists, in their attempt to unveil the truths hidden inside the body. Using theoretical writings (anatomical textbooks) as well as sources more closely linked to daily practices (such as university notes of medical students), this paper seeks to explore the technologies of touch that were displayed in 16th-century anatomical practices and discourses, with the aim of highlighting the epistemological value of the sense of touch in early modern inquiries about Nature and the human body.

This paper investigates whether conditional accounting conservatism has informational benefits to financial market participants. Using a large sample of French firms over the period 2001-2014, we report that accounting conservatism improves the firm information environment by providing verifiable information. We specifically document that increases in accounting conservatism are associated with more accurate analyst earnings forecasts, less dispersed forecasts and less volatility in forecast revisions. We also provide evidence that increases in firm accounting conservatism lead to subsequent increases in stock market liquidity, tested on the price impact dimension. Overall, our findings are in line with conservatism being useful to financial markets participants such as financial analysts and investors. [less ▲]

The design of drug delivery systems (DDS) often requires biodegradable and biocompatible materials that allow safe retention and controlled release of the drug. In this respect, poly(ethylene oxide)-b-polyphosphoester amphiphilic block copolymers are known to self-assemble into polymer micelles when placed in water are appropriate drug carriers. In this work, an unsaturated alkene side-chain was introduced on the cyclic phosphate monomer according to a one-step reaction followed by its organocatalyzed polymerization initiated by a poly(ethylene oxide) macroinitiator. After self-assembly into water, the micelles were cross-linked by UV irradiation. Then, these cross-linked micelles have been loaded by doxorubicin, which is a drug to use in cancer therapy. We observed that the doxorubicin loading increased with the number of double bonds on the polyphosphate block of non-cross-linked micelles. This diblock amphiphilic copolymer bearing pendant unsaturations appears thus particularly promising candidate to build micellar drug delivery systems for intravenous injection. [less ▲]

Macroporous polymer monoliths with interconnected structures have attracted considerable interests in the last decades and sustain many applications in the fields of supported catalysis, chromatography, microfluidic, water purification, membrane separation, tissue engineering, to name but a few. A very popular and straightforward synthetic approach for such open-cell polymers is the High Internal Phase Emulsion (HIPE) polymerization method. The latter consists in three steps: (i) stabilization of an emulsion in which an internal phase with a volume fraction higher than 74% is dispersed within a minor continuous phase containing a polymer network precursor, (ii) curing of the polymer phase by polymerization or crosslinking reactions, (iii) removal of the internal phase to release the porosity. The surface properties and morphology of the polyHIPEs are important features that must be controlled and adjusted for each applications. In this context, we prepared by controlled radical polymerization a series of well-defined amphiphilic copolymers having different hydrophilic-lipophilic balance (HLB) and chain-ends, used it as stabilizers for the emulsion-templated polymerizations and demonstrated the crucial effect of the structure of the macromolecular surfactant on the morphology of the polyHIPEs. Finally, the physical and chemical anchoring of the macromolecular surfactants at the surface pores were also considered for tuning the surface properties of the porous monoliths. [less ▲]

Polyurethane (PUs) is one of the most important polymers and finds applications as elastomers, coatings, adhesives and sealants for automotive or construction. PU is also a material of choice in the biomedical domain due to its good biocompatibility, biodegradation and mechanical properties. Especially, PUs hydrogels have been developed in the last years for biomedical applications such as soft contact lenses, wound dressing, drug delivery systems and scaffolds for tissue engineering. Traditionally, PUs are synthesized by a step-growth polymerization between diols and diisocyanates. Because of toxicity issues and a possible interdiction of isocyanates, we focused on developing new PU hydrogels using a non-isocyanate route (Figure 1). The polyurethanes formed by this route are called NIPU (for Non-Isocyanate PolyUrethane). Firstly, chemically cross-linked NIPU gels were synthesized by solvent-free polycondensation between a hydrophilic CO2-sourced polyethyleneglycol bi-cyclic carbonate and a diamine in the presence of a crosslinker. Then, NIPU gels were swelled in water till water equilibrium before characterization of their mechanical properties by compression tests. The influence of the cross-linking ratios (diamine/crosslinker ratio) and diamine structure on the swelling and the compression properties were studied. To reinforce the compression properties of NIPU hydrogel (increase in stress at break, strain at break and compression modulus), a nanofiller was dispersed in the cyclic carbonate/diamine/crosslinker formulation prior to polymerization. For the first time, nanocomposite NIPU hydrogels with high water contents (up to 80%) and good compression properties have been prepared by using low clay content. [less ▲]

Thanks to their fascinating physical properties such as high surface area, multidimensional electron transport pathways and good mechanical strength, three dimensionally (3D) interconnected carbon porous frameworks have emerged as attractive materials for various electrochemical energy storage/conversion devices, including Li-ion batteries (LIBs), Li−O2 batteries, Li−S batteries, supercapacitors, and fuel cells. A hierarchically structured macro- and mesoporous N-doped carbon with dispersed Fe2O3 nanoparticles (NDC@Fe2O3) is prepared by thermal treatment of a novel composite composed by PMMA particles decorated by graphene oxide (GO), PPy and iron salts. The NDC@Fe2O3 composite exhibited high surface area with a hierarchical pores structure. Integrated as a lithium ion battery anode, NDC@Fe2O3 exhibited high reversible capacity of 930 mA h/g over 200 cycles. The combination of Fe2O3 nanoparticles with porous carbon to form hybrid anode has been an efficient way to maintain the electronic integrity of the whole electrode since the carbon acts as a buffer layer to accommodate the volume variation and to provide multidimensional electron transport pathways during the charge/discharge process.
