Buildings notably contribute to global environmental negative impacts due to consumption of both embodied energy and natural resources as well as various emissions during their whole life cycle. It is therefore necessary to develop practices to reduce these impacts, mainly by reducing the part of non-renewable resource in material as well as by ensuring the lowest energy consumption possible during their lifetime. New developments in natural fibres and their use in insulating materials can lead to significant improvement in building environmental impact. For this purpose, assessment of environmental performance is needed to support both the design and the production of (new) fibre based insulation solutions. In this context, the Life Cycle in Practice (LCiP) project helps SMEs to reduce the environmental impacts of their products and services across the entire life cycle. Within the frame of this project, Isohemp (BE) hemp concrete block impact is evaluated in a cradle-to-gate LCA. Functional unit is a pallet of hemp concrete blocks ready for shipping. It represents about 1.3 m³ of blocks. Hemp blocks are made by pressing a mix of hemp shives, hydraulic and hydrated limes, and water. Long term carbon storage due to lime carbonation induces a large benefit in Climate Change (CC) category. The balance of the CC indicator for hemp cultivation is also favorable due to carbon dioxide uptake by the photosynthesis occurring during the plant growth. Life Cycle Assessment of hemp concrete blocks ready to ship has also highlights some improvements that can easily be made at the packaging level in order to lower the global environmental impact and increase the sustainability of this insulation material. Data are processed in SimaPro 8 software, with Ecoinvent 3 and ELCD 3 databases, and analyzed with the CML IA method. This method is compliant with the indicators required by EN15804 standard in order to communicate on the environmental performance of Isohemp blocks. [less ▲]

In Bacillus licheniformis 749/I, the induction of BlaP beta-lactamase relies on a complex regulation system. During this process, the intracellular repressor BlaI is inactivated by a dipeptide coming from the peptidoglycan (PG) degradation via an “AND Gate” regulation. This regulation involves the cellular stress induced by the beta-lactam, the membrane receptor BlaR1 and the PG turnover. Briefly, the induction occurs when the extracellular domain of BlaR1 is acylated by the antibiotic which leads to a reorganization of the transmembrane segments and the receptor autocleavage. Simultaneously, the beta-lactam partially inhibits the penicillin-binding protein 1 (PBP1), triggering increased PG turnover and accumulation of PG fragments. Some of these fragments could enter in the cytoplasm and undergo enzymatic degradations which lead to the formation of the pro co-activator (tripeptide L-Ala-D-Glu-m-A2pm). This pro co-activator generates the co-activator, the dipeptide D-Glu-m-A2pm. Nowadays the nature and the concentration of PG fragments inside the cytoplasm are unknown. Therefore, the development of different analytical methods is required in order to identify those cytoplasmic fragments. In this poster, three different ways to separate PG fragments are discussed.

Our study focuses on Abnormal Bodily Experiences [ABE] in people with schizophrenia. We have created a specific questionnaire for this study – based on the study of Stanghellini et al. (2012) and the third dimension of the EASE scale (body experiences) (Parnas et al. 2005). Our research follows an analytical method called “empirical-phenomenological”. Our population is made up of 50 schizophrenic subjects. The average age of subjects was 37 years. There are no exclusion criteria regarding gender or control sample. Analyzes are qualitative. We observed that ABE are very present symptoms in people with schizophrenia. Indeed, in our sample, only one patient was asymptomatic. We also observed that all categories and subcategories were present in our sample. These results should help to refine and clarify the diagnosis of schizophrenia and open up significant opportunities for psychotherapeutic dimension. [less ▲]

Introduction: from a phenomenological perspective, anorexic female patients seem to experience difficulties regarding the subjective feeling of their own body (embodiment) and their personal identity, which lead to an intersubjectivity impairment within social interactions. Following these findings, this study investigates the “body-for-others” concept (Sartre, 1943) and altruistic hypotheses from the ethologist Albert Demaret (1973) in a sample of anorexic female patients. Two main hypotheses are tested: anorexic patients are expected to define themselves mostly through the gaze of others and as more altruistic than control participants. Method: this study included 67 anorexic female patients (based on the DSM-IV criteria) and 246 control female participants. Three self-reported questionnaires were used: the Eating Disorder Inventory: EDI-II of Garner (French version), the Identity and Eating Disorders questionnaire: IDEA of Stanghellini (French version translated and adapted by us) to assess the “body-for-others” concept and 17 complementary items for the altruistic dimension. Mann-Whitney non-parametric tests were used to compare the two groups. Results: results show that anorexic patients obtain higher scores than the control group for the three questionnaires (p<0,001 for all measurements). Discussion: the IDEA questionnaire enriches the knowledge relative to the body-self relationship and the first-person perspective, which is essential for a phenomenological approach. Furthermore, the promising results concerning the altruistic dimension in anorexia nervosa should be evaluated in future research. Nevertheless, a better validity of the items assessing the altruistic dimension is needed. [less ▲]

Introduction The diagnostic entity of heboidophrenia has been consigned to oblivion despite its clinical, prognostic, criminogenic value. At the core of this diagnosis lies specifics interactions between psychosis and psychopathy. The diagnosis was first coined by Kalhbaum in 1890, was revived by Anglo-Saxon literature in the first half of the 20th century, and by French psychiatrists in the late 90’. Method We integrated literary sources, clinical experience and an own pilot study as a stepping-stone for a more in-depth research. Cases (n=20) were selected out of samples of Mentally Disordered Offenders in Belgian Medium and High Risk Forensic Facilities. Files, records and therapist’s experiences were quantitatively analysed iteratively to cull subtypes from each other. We here present preliminary qualitative results, more indepth qualitative and quantitative results will be produced. Results The diagnosis subsumes more than a mere DSM-IV-TR Axis I & II comorbidity, it can be seen from a developmental perspective, or from a structural perspective. Both vantage points suggest an interplay between the (paranoid) psychotic process and the antisocial behaviour, where both trigger and induce each other. At this point, we found evidence for three subtypes modes of interplay; 1) mood instability patterns induced either psychopathic or psychotic phenotypic presentation, 2) according to personality organization and its defensive functioning (were psychopathy defends against psychosis), and 3) phenotypic expression of both components (psychopathy and psychosis) linearly co-dependent. Discussion Despite its incremental value, little is known about the therapeutic prospects of this diagnosis. Current results indicate that these patients do question competency to answer for their deeds in a peculiar manner, relapse more often, reoffend more often, do evade treatment opportunities (if they have any), act out more often (in both antisocial and psychotic ways), induce a particular negative counter-transference in psychiatric teams, etc. Because of these particularities and their versatile phenotype presentation, heboidophrenia patients cannot simply be assimilated to the “high risk & high care” population, but need special supervision and clinical insight. In this research, we aim(ed) at discerning semiologic signs in order to support the diagnostic process. [less ▲]

Incarceration leads to a break between an individual and one’s social environment, inducing significant losses of identity (Touraut, 2014). Tough delinquent identity remains prominent, during their incarceration, some inmates invest their role of father. Investing his role of father and thus his father’s identity allows the inmate to break away with delinquent’s identity (Tripp, 2009; Walker, 2009). Moreover, research on desistance underlines that turning point like job, marriage or parenthood supports the transition from criminal life to conventional life (Laub et Sampson, 2003; Lebel, Burnett, Maruna & Bushway, 2008). Indeed, becoming parent is a stage in life cycle that can shape one’s lifestyle. From qualitative researches conducted with father inmates since at least 6 months, we have identified the link between investment in parenting and desistance. The hypothesis is that investment in parenting has a positive impact on father’s prison experience, parenting sense of competence and it will support desistance process. A semi-structured interview and several questionnaires assessing relational and social life have been used in this context (WHOQOLbrief, EPS, ESUL, educational attitudes, QAECEP). First results highlight that parenting during incarceration can be difficult. Some inmates try to keep it with visits between inmate fathers and their children. These visits are influenced by different factors and have a positive impact on prison experience. Indeed, with these visits, inmates maintain a link with their children. That is a source of support and hope during incarceration. That allows investment in one father’s identity. [less ▲]

Valorising CO2 as a renewable C1 feedstock for producing added value building blocks is the scope of many academic and industrial researches. Carbon dioxide is a thermodynamically and kinetically stable molecule that can be converted into five membered cyclic carbonates by coupling with epoxides using organometallic complexes or organocatalysts. To date, the identification and development of highly efficient (organo)catalysts under mild experimental conditions still remains challenging. In particular, the synthesis of six membered cyclic carbonates by the CO2/oxetane coupling using such organocatalysts has never been reported to our knowledge. In this context, we developed a new highly efficient bicomponent homogeneous organocatalyst composed of an ammonium salt as the catalyst and fluorinated single or double hydrogen bond donor activators (HBD). First, the efficiency of this new organocatalyst for the fast and selective CO2/epoxide coupling was investigated through detailed kinetic studies by IR spectroscopy under pressure and results were compared with the most efficient organocatalysts reported in the literature. This study was completed by molecular modeling in order to elucidate the reaction mechanism. DFT calculations showed that the hexafluoroisopropanol functionalities of HBDs strengthened the proton donor capability and allowed a better stabilization by hydrogen bonding of the intermediates and transition states. Finally, the use of this dual organocatalyst was extended to the coupling of CO2 with less reactive oxetanes to produce hydroxyl telechelic oligocarbonates. [less ▲]

L'un des principaux modèles d'évaluation et d’intervention auprès des jeunes délinquants souligne l'importance d'adapter l'intensité de l’intervention au niveau de risque, de s'assurer que celle-ci cible les facteurs criminogènes et tienne compte de la réceptivité du jeune contrevenant. Il s'agit du modèle RNR, aujourd’hui largement reconnu pour son efficacité dans le domaine de la délinquance juvénile (Andrews, Bonta, & Wormith, 2011). L’évaluation du délinquant basée sur ce modèle améliorerait la justesse des décisions cliniques, permettrait une meilleure classification et identification de profils, proposerait des interventions ciblées ainsi qu’une évaluation efficace des programmes (Andrews & Bonta, 1998). Ce type d’approche est toutefois mis en balance avec le modèle GLM (Fortune, Ward, & Polaschek, 2014) basé sur les forces du jeune et sa responsabilisation. En effet, le modèle RNR peut être compris, dans son extrême, comme contrôlant, cherchant à imposer des normes correspondantes aux dictats de la société, au détriment des intérêts du jeune (Briggs, 2013). Suite à la décision de communautariser la détermination des mesures prises à l’égard des jeunes délinquants en Belgique francophone, notre recherche a pour but d'identifier et de recommander un instrument d'évaluation du jeune à des fins de classification et de gestion de cas en vue d’orienter les mesures ultérieures et interventions. Dans ce contexte, nous présenterons l’outil YLS/CMI 2.0 (Hoge & Andrews, 2011), que nous avons associé à un volet spécifique centré sur l’évaluation des forces du jeune (YCA ; Mackin, Weller, & Tarte, 2004). Nous décrirons le chemin parcouru depuis l’implémentation de l’outil dans les institutions accueillant de jeunes délinquants et nous attarderons sur les intérêts et enjeux de proposer un outil d’évaluation à la croisée des chemins, entre la gestion des risques que le jeune pose et l’importance de considérer ses intérêts et priorités en focalisant sur ses ressources.

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.
