Blanche Gardin, moraliste de notre temps ? Humour, spectacle et formation informelle du sujet hypermoderne
Authors: Roelens Camille 
Published: September 2024

Dans la continuité de précédents travaux sur la part de la formation informelle dans le déploiement de l’éthicité du sujet hypermoderne, nous nous intéresserons dans ce texte aux enseignements que l’on peut tirer, lorsqu’on travaille dans le champ scientifique de l’éthique pratique et appliquée en éducation et formation, du succès contemporain des spectacles humoristiques « seule en scène » de l’humoriste française Gardin. Une première partie de l’étude nous permet d’en restituer les aspects les plus heuristiques. Une seconde esquisse trois pistes herméneutiques à explorer pour mieux comprendre en quoi Gardin s’érige in fine en éducatrice/formatrice informelle des passions de son public, du prisme le plus compréhensif et biographique (en lien avec ses études de sociologie) au plus critique, montrant en quoi elle glisse parfois de la position réflexive du moraliste classique à une posture moralisatrice plus problématique, car tendant davantage vers le fait de faire la leçon.
L’évaluation formative : pratiques d’évaluation en classe et dilemmes du personnel enseignant dans la mise en oeuvre
Authors: Ruminot Carolina 
Published: September 2024

Cette recherche examine l’état actuel des connaissances, des contraintes et des défis existants dans la pratique de l’évaluation formative chez des enseignants du primaire au Chili. Les résultats de 17 entretiens semi-dirigés réalisés à la suite d’une formation de dix ateliers de développement professionnel indiquent que le personnel enseignant de l’étude démontre une préoccupation à repenser ses pratiques évaluatives en classe. Cependant, une approche traditionnelle reste mobilisée en raison, d’une part, du manque de formation et, d’autre part, de la forte concentration du système éducatif sur l’évaluation standardisée. Les analyses fournies dans l’étude révèlent des tensions dans la quête d’équilibre entre les évaluations formatives et sommatives. Or, les réflexions posées sur les connaissances des enseignants à l’égard des défis rencontrés dans leurs pratiques peuvent alimenter les réflexions pédagogiques quant à l’impact des évaluations standardisées sur les pratiques des enseignants et sur les apprentissages mathématiques des élèves.

Face à des élèves qui cumulent les formes de vulnérabilités, les acteurs du lycée professionnel (LP) conçoivent des dispositifs éducatifs innovants, notamment pour l’évaluation. Aussi, cette recherche participative et pluridisciplinaire autour de l’enseignement de l’anglais en CAP s’articule autour de deux axes : 1) l’impensé d’une évaluation diagnostique comme objet frontière et 2) l’évaluation des effets de la recherche participative sur les membres du collectif (enseignants, inspecteurs, chercheurs). Une méthodologie qualitative de recueil de données et d’analyse de contenus a été mise en oeuvre. Les résultats montrent le besoin exprimé de (re)mobiliser les acteurs (enseignants et élèves), en partie à travers des interactions entre enseignants, ainsi qu’avec les chercheurs, autour des pratiques d’évaluation. Les enseignants verbalisent leur développement professionnel grâce aux temps de coopération sur l’objet frontière. Les valuations émergent tant par la recherche que par la coconception de l’évaluation, au sein d’une communauté de pratique pluricatégorielle.
Étude visant à identifier des facteurs ayant le potentiel de réduire les écarts d’anxiété mathématique observés entre les garçons et les filles francophones de 15 ans du Québec, à partir d’une analyse des données du PISA de 2003 et 2012
Authors: Vohl Patricia , Loye Nathalie 
Published: September 2024

Dans une étude antérieure (Vohl & Loye, 2024), nous avons montré qu’en moyenne, les filles québécoises francophones de 15 ans se disent davantage anxieuses à l’égard des mathématiques que les garçons et ce, sur l’ensemble du continuum des performances. Nous avons également montré que performances en mathématique et anxiété mathématique sont deux phénomènes négativement corrélés. Dans le présent article, nous souhaitons identifier des facteurs qui pourraient permettre d’expliquer les écarts d’anxiété mathématique observés entre les filles et les garçons. En prenant appui sur le modèle du contrôle et de la valeur de Pekrun (2006), nous vérifions si les écarts de concept de soi, de valeur intrinsèque et de valeur utilitaire observés entre les filles et les garçons expliquent complètement les écarts d’anxiété mathématique. Nos résultats révèlent que les écarts de concept de soi expliquent près de 70 % des écarts d’anxiété mathématique relevés chez les élèves francophones du Québec.

Published: September 2024

Background
Although chemoradiotherapy is an effective treatment for esophageal cancer, its feasibility in esophageal cancer with cirrhosis remains largely unclear.

Methods
We retrospectively studied 11 patients with superficial esophageal cancer with liver cirrhosis (Child-Pugh score ≤8) who underwent radical chemoradiotherapy from four centers, and the overall survival rate, local control rate and adverse events at 1 and 3 years were explored.

Results
The median age of the included patients was 67 years (Inter-Quartile Range 60–75 years). Complete response was observed in most patients (n = 10, 90.9%), and the remaining patient was unevaluable. The 1- and 3-year overall survival and local control rates were 90.9% and 90.9%, and 72.7% and 63.6%, respectively. Hematotoxicity was a common adverse reaction, and seven patients developed radiation esophagitis, with grade 3–4 observed in two cases. All cases of radiation dermatitis (n = 4) and radiation pneumonia (n = 2) were grade 1–2. Gastrointestinal bleeding occurred in two patients, including one with grade 1–2 bleeding, and one died.

Conclusion
Radical chemoradiotherapy is a potential treatment option for patients with superficial esophageal cancer complicated with cirrhosis. However, it can increase the risk of bleeding, which warrants prompt recognition and intervention.
Mitigating Climate Change Through Energy Recovery at Dandora Wastewater Treatment Plant, Nairobi County, Kenya
Authors: Omollo Mercy Achieng , Kirubi Gathu , Manohar Ram 
Published: September 2024

The world is experiencing an increase in the rate of greenhouse gases emissions accumulating in the atmosphere due to natural and anthropogenic causes. These gasses absorb and emits radiation within the thermal infrared range thus contributing to the Green House effect. The building up of greenhouse gasses beyond the natural acceptable levels can change the earth's climate thus contributing to climate change. To mitigate climate change, there is need to cease the increase of greenhouse gases either by not adding them into the air and or increasing the earths’ ability to withdraw them out of air. This study looked into mitigating climate change through energy recovery at Dandora wastewater treatment plant in Nairobi. The study employed both primary and secondary data. Operational data on the raw sewer chemical oxygen demand and biological oxygen demand levels was collected from the plant between 2007 and 2013. MS excel was used to analyze the data in order to cipher the trends of biological oxygen demand & chemical oxygen demand loadings and removals and thus estimation of biogas and methane likely to be generated and energy recovery thereof. The relationship between these two variables were tested through a Correlation coefficient test. The two-level computations estimated the daily biogas generation at the treatment plant as 2738m3. The study estimates methane generated to be equivalent to 68398MJ/Day of energy. Considering the calorific value of LPG of 46MJ/kg, this is equivalent to 495 cylinders daily serving 2974 households daily. The findings indicate that recovery of energy from the Plant mitigates climate change through reduction of emissions by 16 tCO2-e per day. The energy recovered had a positive correlation with the emission reduction at a high value of r= 0.99. The study concludes that energy recovery from wastewater treatment plant reduces emission thus mitigates climate change.
Biocomposites based on chemically modified cellulose fibers with renewable fatty‐acid‐based thermoplastic systems: Effect of different fiber treatments
Authors: Reulier M. , Perrin R. , Avérous L. 
Published: May 2016

ABSTRACTAdvanced biocomposites, based on binary and ternary systems, were developed with thermoplastic matrices such as thermoplastic polyurethane (TPU) and polyamide (DAPA) obtained from dimers of fatty acids, and cellulose fibers (CF). The CF were modified to display high interfacial adhesion and compatibility with the rather hydrophobic matrices. Different routes were considered such as grafting onto with prepolymers, or grafting from with aromatic isocyanate or fatty acid. An original approach of this work is to consider CF as a polyol with an equivalent hydroxyl index obtained by titration. In order to understand better the effect of each phase, the resulting modified CF were tested with neat TPU and DAPA matrices. The most promising fibers treatments were then tested with 80/20 and 50/50 wt %/wt % TPU/DAPA blends. Properties at the molecular and macromolecular scale were investigated. Improvement of the interfacial adhesion between the fibers and the polymers were observed. From the different grafting approaches tested, the best performing were the isocyanate‐terminated prepolymer and the silane‐terminated prepolymer modifications. In comparison with neat CF, modification with isocyanate‐terminated prepolymer improved threefold the storage and Young's modulus of TPU biocomposites. © 2016 Wiley Periodicals, Inc. J. Appl. Polym.

Diving for science ‐ science for diving: volunteer scuba divers support science and conservation in the Mediterranean Sea
Authors: Cerrano Carlo , Milanese Martina , Ponti Massimo 
Published: May 2016

Abstract

Recreational diving engages 20 million people worldwide. Most of the literature refers to tropical destinations but at least 1 million dives per year take place in Mediterranean marine protected areas (MPAs).
Divers may negatively affect underwater habitats. However, if effectively engaged, they can contribute to science, territorial management and more sustainable local economies.
During 2006–2014, volunteers trained by the not‐for‐profit organization Reef Check Italia (RCI) completed 24 714 observations and 2417 dives in six Mediterranean countries, contributing to a dataset that supports scientific papers about climate change, rare and non‐indigenous species (NIS), and informs MPA management decision‐making.
The wide range of opportunities offered by this dataset is illustrated with two examples relevant to marine conservation in the context of MPA management. They concern: (i) the spread of the NIS Caulerpa cylindracea along the Ligurian coasts, with a focus on Portofino MPA, and (ii) the distribution and abundance of protected species in the Portofino MPA.
A diver‐focused survey showed that RCI volunteers are highly committed, and that participation in RCI activities has led to a better understanding of, and a sense of stewardship towards, favoured dive sites and the marine world. Knowing who volunteers are, and why they volunteer in their favourite sector, is crucial to designing citizen‐science based projects able to achieve their multiple goals.

Published: May 2016

SummaryDREADDs, designer receptors exclusively activated by designer drugs, are engineered G protein‐coupled receptors (GPCR) which can precisely control GPCR signaling pathways (for example, Gq, Gs, and Gi). This chemogenetic technology for control of GPCR signaling has been successfully applied in a variety of in vivo studies, including in mice, to remotely control GPCR signaling, for example, in neurons, glia cells, pancreatic β‐cells, or cancer cells. In order to fully explore the in vivo applications of the DREADD technology, we generated hM3Dq and hM4Di strains of mice which allow for Cre recombinase‐mediated restricted expression of these pathway‐selective DREADDs. With the many Cre driver lines now available, these DREADD lines will be applicable to studying a wide array of research and preclinical questions. genesis 54:439–446, 2016. © 2016 Wiley Periodicals, Inc.
Mutualism exploitation: predatory drosophilid larvae sugar‐trap ants and jeopardize facultative ant‐plant mutualism
Authors: Vidal Mayra C. , Sendoya Sebastian F. , Oliveira Paulo S. 
Published: May 2016

AbstractAn open question in the evolutionary ecology of ant‐plant facultative mutualism is how other members of the associated community can affect the interaction to a point where reciprocal benefits are disrupted. While visitingQualea grandiflorashrubs to collect sugary rewards at extrafloral nectaries, tropical savanna ants deter herbivores and reduce leaf damage. Here we show that larvae of the flyRhinoleucophenga myrmecophaga, which develop on extrafloral nectaries, lure potentially mutualistic, nectar‐feeding ants and prey on them. Foraging ants spend less time on fly‐infested foliage. Field experiments showed that predation (or the threat of predation) on ants by fly larvae produces cascading effects through three trophic levels, resulting in fewer protective ants on leaves, increased numbers of chewing herbivores, and greater leaf damage. These results reveal an undocumented mode of mutualism exploitation by an opportunistic predator at a plant‐provided food source, jeopardizing ant‐derived protection services to the plant. Our study documents a rather unusual case of predation of adult ants by a dipteran species and demonstrates a top‐down trophic cascade within a generalized ant‐plant mutualism.

AbstractBei allen Arten der Rissinitiation in bindigen Böden ist deren Zugfestigkeit die wesentliche Kenngröße des Materialwiderstands. Direkte und indirekte Methoden zur experimentellen Ermittlung der Zugfestigkeit wurden an unterschiedlich bindigen Böden vergleichend bei verschiedenen Proctor‐Verdichtungsgraden und Wassergehalten an gesättigten und ungesättigten Proben durchgeführt. Anhand der Versuchsergebnisse werden Aussagen zu Präzision, Zuverlässigkeit und Qualität der Versuchsmethoden abgeleitet, welche Entscheidungsgrundlagen zur Festlegung der für eine spezielle Fragestellung angemessenen Versuchsmethode sind.Comparison of direct and indirect test methods for determining the tensile strength of cohesive soils. Related to the initiation of cracks in cohesive soils, the tensile strength is the most important parameter concerning resistance. Direct and indirect methods for the experimental determination of the tensile strength of different cohesive soils were comparatively investigated and evaluated. The experiments were carried out on saturated and unsaturated specimen at various degrees of compaction and water content. Based on the results, the different experimental approaches are compared in respect to precision and reproducibility. This comparison and evaluation might be a basis to find the appropriate test method for a specific impact.
In silico Structural characterization of podocin and assessment of nephrotic syndrome‐associated podocin mutants
Authors: Mulukala Sandeep Kumar Narasimha , Nishad Rajkishor , Kolligundla Lakshmi Prasanna , Saleem Moin A. , Prabhu Nagu Prakash , Pasupulati Anil Kumar 
Published: May 2016

AbstractNephrotic syndrome (NS) is manifested by hyperproteinuria, hypoalbuminemia, and edema. NPHS2 that encodes podocin was found to have most mutations among the genes that are involved in the pathophysiology of NS. Podocin, an integral membrane protein belonging to stomatin family, is expressed exclusively in podocytes and is localized to slit‐diaphragm (SD). Mutations in podocin are known to be associated with steroid‐resistant NS and rapid progression to end‐stage renal disease, thus signifying its role in maintaining SD integrity and podocyte function. The structural insights of podocin are not known, and the precise mechanism by which podocin contributes to the architecture of SD is yet to be elucidated. In this study, we deduced a model for human podocin, discussed the details of transmembrane localization and intrinsically unstructured regions, and provide an understanding of how podocin interacts with other SD components. Intraprotein interactions were assessed in wild‐type podocin and in some of its mutants that are associated with idiopathic NS. Mutations in podocin alter the innate intraprotein interactions affecting the native structure of podocin and its ability to form critical complex with subpodocyte proteins. © 2016 IUBMB Life, 68(7):578–588, 2016
Comparative Transcriptomics of Alternative Developmental Phenotypes in a Marine Gastropod
Authors: Lesoway Maryna Pauline , Abouheif Ehab , Collin Rachel 
Published: May 2016

ABSTRACTAlternative phenotypes are discrete phenotypic differences that develop in response to both genetic and environmental cues. Nutritive embryos, which arrest their development to serve as nutrition for their viable siblings, are an example of an alternative developmental phenotype found in many animal groups. Females of the marine snail,Crepidula navicella, produce broods that consist mainly of nutritive embryos and a small number of viable embryos. In order to better understand the genetic mechanisms that lead to the development of alternative phenotypes in this species, we compared the transcriptomes of viable and nutritive embryos at the earliest stage that we were able to distinguish visually between the two. Using high‐throughput Illumina sequencing, we assembled and annotated a de novo transcriptome and compared transcript levels in viable and nutritive embryos. Viable embryos express high levels of transcripts associated with known developmental events, while nutritive embryos express high levels of apoptosis‐related transcripts. Gene Ontology term enrichment with GOSeq found that these are associated with the negative regulation of apoptotic processes. This enrichment, combined with morphological evidence, suggests that apoptosis is important in the formation of gastrula‐like nutritive embryos. Apoptosis has been implicated in the development of alternative phenotypes in other animal groups, raising the possibility that this mechanism's role in alternative phenotypes is conserved in gastropod development. We suggest possible alternative mechanisms of nutritive embryo development. Most importantly, we contribute further evidence to the hypothesis that nutritive embryos are an alternative developmental phenotype.
Randomized‐controlled trial of mindfulness‐based cancer recovery versus supportive expressive group therapy among distressed breast cancer survivors (MINDSET): long‐term follow‐up results
Authors: Carlson Linda E. , Tamagawa Rie , Stephen Joanne , Drysdale Elaine , Zhong Lihong , Speca Michael 
Published: May 2016

AbstractBackgroundMindfulness‐based cancer recovery (MBCR) and supportive expressive group therapy (SET) are two well‐validated psychosocial interventions, but they have not been directly compared, and little is known about long‐term outcomes. This comparative effectiveness study measured the effects of these two interventions immediately following the groups and for 1 year thereafter in distressed breast cancer survivors.MethodsTwo hundred fifty‐two distressed Stage I–III breast cancer survivors were randomized into either MBCR or SET. Women completed questionnaires addressing mood, stress symptoms, quality of life, social support, spirituality and post‐traumatic growth before and after the interventions, and 6 and 12 months later.ResultsImmediately following the intervention, women in MBCR reported greater reduction in mood disturbance (primarily fatigue, anxiety and confusion) and stress symptoms including tension, sympathetic arousal and cognitive symptoms than those in SET. They also reported increased emotional and functional quality of life, emotional, affective and positive social support, spirituality (feelings of peace and meaning in life) and post‐traumatic growth (appreciation for life and ability to see new possibilities) relative to those in SET, who also improved to a lesser degree on many outcomes. Effect sizes of the time × group interactions were small to medium, and most benefits were maintained over 12 months of follow‐up.ConclusionsThis study is the first and largest to demonstrate sustained benefits of MBCR in distressed breast cancer survivors relative to an active control. MBCR was superior to SET for improving psychological well‐being with lasting benefits over 1 year, suggesting these women gained long‐lasting and efficacious tools to cope with cancer.Trial RegistrationRegistered on clinicaltrials.gov number NCT00390169, October 2006.
