Le compagnonnage dans l’enseignement supérieur : accompagner et apprendre par les pairs pour transformer sa pratique professionnelle
Comprend des références bibliographiquesLe présent article revient sur les premiers mois d’un dispositif d’accompagnement des enseignants et enseignants chercheurs nouvellement recrutés à l’Université d’Angers, en référence au modèle compagnonnique. Adossée à diverses formalisations de l’expertise enseignante, dont le SoTL, l’expérimentation engagée à l’UA a pour objectifs d’encourager le développement professionnel par la verbalisation entre pairs de l’expérience professionnelle et la transformation des pratiques pédagogiques, dans le cadre d’un engagement politique de l’établissement. Pensé initialement à l’attention des nouveaux EEC, ce dispositif s’avère profitable aux deux membres du binôme, au terme d’une co-construction et d’un co-cheminement dans la réflexivité sur les pratiques professionnelles

Antineutrino emission and gamma background characteristics from a thermal research reactor
The detailed understanding of the antineutrino emission from research
reactors is mandatory for any high sensitivity experiments either for
fundamental or applied neutrino physics, as well as a good control of the gamma
and neutron backgrounds induced by the reactor operation. In this article, the
antineutrino emission associated to a thermal research reactor: the OSIRIS
reactor located in Saclay, France, is computed in a first part. The calculation
is performed with the summation method, which sums all the contributions of the
beta decay branches of the fission products, coupled for the first time with a
complete core model of the OSIRIS reactor core. The MCNP Utility for Reactor
Evolution code was used, allowing to take into account the contributions of all
beta decayers in-core. This calculation is representative of the isotopic
contributions to the antineutrino flux which can be found at research reactors
with a standard 19.75\% enrichment in U. In addition, the required
off-equilibrium corrections to be applied to converted antineutrino energy
spectra of uranium and plutonium isotopes are provided. In a second part, the
gamma energy spectrum emitted at the core level is provided and could be used
as an input in the simulation of any reactor antineutrino detector installed at
such research facilities. Furthermore, a simulation of the core surrounded by
the pool and the concrete shielding of the reactor has been developed in order
to propagate the emitted gamma rays and neutrons from the core. The origin of
these gamma rays and neutrons is discussed and the associated energy spectrum
of the photons transported after the concrete walls is displayed.Comment: 14 pages, 11 figures, Data in Appendix A and B (13 pages

Retrospective analysis of a cohort of HIV-infected patients on antiretroviral therapy in Abidjan (2003 to 2017)
Background: Antiretroviral therapy (ART) has been successful in improving clinical outcomes for HIV-positive patients, but efforts are needed to improve life expectancy and quality of life. This study aimed to analyze a long-term ART cohort and assess patients' life expectancy.
Methods: A retrospective cohort study was conducted at the infectious and tropical diseases department of the University Teaching Hospital of Treichville from 2003 to 2017. Data analysis was done using VBA access and XLSTAT 2018 excel software. Patients on post-exposure chemoprophylaxis and prevention of mother-to-child transmission were excluded.
Results: Out of 19,567 patient records, 49.60% were included, 72.43% were in 1st line, and 50.10% were over 50 years old, mostly female 58.49%, 98.4% HIV1. 74.31% had a CD4/mm3 (Nadir) count <350. The patients were essentially on the 2IN+INN regimen (72.31%), TDF + XTC + EFV (20.57%). The average duration under treatment 6.15 [0-13.67] ±3.94 years, the average duration under a line of treatment 4.33 [0-14.04] ±2.96 years. Life expectancy was 10.37 years. It is higher in patients on 2IN+IPr (12.21 years) versus 10.12 years in patients on 2IN+INN. The comparison of duration on a line according to the CD4 counts and the line of treatment did not show a significant difference p>0.05.
Conclusions: The study concluded that ART significantly improved the life expectancy of patients, adherence could be improved to further enhance the benefits of ART. The use of new combinations of ART may reduce events related to non-compliance
Transport anomalies across the quantum limit in semimetallic BiSb
We report on a study of electronic transport in semi-metallic
BiSb. At zero field, the system is a very dilute Fermi liquid
displaying a T resistivity with an enhanced prefactor. Quantum
oscillations in resistivity as well as in Hall, Nernst and Seebeck responses of
the system are detectable and their period quantifies the shrinking of the
Fermi surface with antimony doping. For a field along the trigonal axis, the
quantum limit was found to occur at a field as low as 3T. An ultraquantum
anomaly at twice this field was detected in both charge transport and Nernst
response. Its origin appears to lie beyond the one-particle picture and linked
to unidentified many-body effects.Comment: 5 pages inculding 4 figure
The costs of functional gastrointestinal disorders and related signs and symptoms in infants: a systematic literature review and cost calculation for England
OBJECTIVES: To estimate the cost of functional gastrointestinal disorders (FGIDs) and related signs and symptoms in infants to the third party payer and to parents. STUDY DESIGN: To estimate the cost of illness (COI) of infant FGIDs, a two-stage process was applied: a systematic literature review and a COI calculation. As no pertinent papers were found in the systematic literature review, a 'de novo' analysis was performed. For the latter, the potential costs for the third party payer (the National Health Service (NHS) in England) and for parents/carers for the treatment of FGIDs in infants were calculated, by using publicly available data. In constructing the calculation, estimates and assumptions (where necessary) were chosen to provide a lower bound (minimum) of the potential overall cost. In doing so, the interpretation of the calculation is that the true COI can be no lower than that estimated. RESULTS: Our calculation estimated that the total costs of treating FGIDs in infants in England were at least £72.3 million per year in 2014/2015 of which £49.1 million was NHS expenditure on prescriptions, community care and hospital treatment. Parents incurred £23.2 million in costs through purchase of over the counter remedies. CONCLUSIONS: The total cost presented here is likely to be a significant underestimate as only lower bound estimates were used where applicable, and for example, costs of alternative therapies, inpatient treatments or diagnostic tests, and time off work by parents could not be adequately estimated and were omitted from the calculation. The number and kind of prescribed products and products sold over the counter to treat FGIDs suggest that there are gaps between treatment guidelines, which emphasise parental reassurance and nutritional advice, and their implementation
