Analysis of backgrounds for the ANAIS-112 dark matter experiment
No full textThe ANAIS (Annual modulation with NaI(Tl) Scintillators) experiment aims at the confirmation or refutation of the DAMA/LIBRA positive annual modulation signal in the low energy detection rate, using the same target and technique, at the Canfranc Underground Laboratory (LSC) in Spain. ANAIS-112, consisting of nine 12.5 kg NaI(Tl) modules produced by Alpha Spectra Inc. in a 3 × 3 matrix configuration, is taking data smoothly in “dark matter search” mode since August, 2017, after a commissioning phase and operation of the first detectors during the last years in various set-ups. A large effort has been carried out within ANAIS to characterize the background of sodium iodide detectors, before unblinding the data and performing the first annual modulation analysis. Here, the background models developed for all the nine ANAIS-112 detectors are presented. Measured spectra from threshold to high energy in different conditions are well described by the models based on quantified activities independently estimated following several approaches. In the region from 1 to 6keVee the measured, efficiency corrected background level is 3.58±0.02keV-1kg-1day-1; NaI crystal bulk contamination is the dominant background source being 210 Pb , 40 K , 22 Na and 3 H contributions the most relevant ones. This background level, added to the achieved 1keVee analysis threshold (thanks to the outstanding light collection and robust filtering procedures developed), allow ANAIS-112 to be sensitive to the modulation amplitude measured by DAMA/LIBRA, and able to explore at three sigma level in 5 years the WIMP parameter region singled out by this experiment. © 2019, The Author(s)

La présence d’un enseignant supplémentaire comme opportunité pour développer la différenciation et le travail collaboratif : le cas d’un projet pilote au sein du cycle 5-8 ans
No full textFederation Wallonia Brussel from Belgium is engaged in a reform aimed at developing personalized support to sustain differentiation: an additional teacher is in the classroom for a few hours. This paper relates the experiment with 10 schools at the level of the 5-8 years old. Its objective is to document the evolution of representations and practices of differentiation and collaboration. Individual questionnaires were submitted to teachers one year apart. Analysis of data revealed a broadening of pupils’ conceptions. The presence of an additional teacher in the classroom developed a collaborative dynamic and a differentiation beyond the classroom space. At the end of our investigations, it seems that the representation of teacher’s working time doesn’t integrate the collective dimension yet and constitutes an obstacle. professional representation – pedagogical differentiation – change of practice – collaborative practice – co-teaching practice – professional development – teacher working tim
Anais Nin: A case study of personality disorder and creativity
No full textAnais Nin, diarist and author of autobiographical novellas and erotica, and gregarious socialite, was known for her exotic persona and stormy personal life. The concept of personality disorder and the underlying assumption of the buffering capacity that personality affords to stressors are discussed. Against this background, evidence drawn from Nin's diaries, short stories and two biographies suggests that she conformed to the diagnostic criteria of histrionic personality disorder (HPD), with comorbid borderline and narcissistic features, and numerous Axis I symptoms. The proposed origin of the overall dysfunctional histrionic pattern is attributed to her early developmental history, and the maladaptive cognitive mechanisms of dissociation and repression inferred from her writings and shown to conform to the HPD pattern. Finally, it is argued that while Nin may not have displayed the classic divergent cognitive style thought to underlie the association between schizotypy and creativity, her HPD psychopathology was pivotal in shaping her creative products, most famous of which is her diary.

The intuitive quest in the novels of Anais Nin: A reader\u27s guide through the Cities of the Interior
No full textThis work, a reader\u27s guide, explores the five novels of Anais Nin\u27s continuous novel Cities of the Interior through the underlying motif of the intuitive quest. An examination of the characters, symbols, poetic style, and structure of Nin\u27s novels reveals the author\u27s thematic focus on the need for intuitive forms of expression in an often overly rational modern-day society. Each novel is approached as part of a fictional odyssey that relates the theme of the intuitive quest to the three major female characters\u27 contemporary, psychological search for selfhood. Author and reader are considered throughout as the protagonists\u27 co-questers. In its pattern of separation, initiation, and return, as described by Joseph Campbell in The Hero with a Thousand Faces and Myths to Live By, the course of each heroine\u27s journey is compared to that of the mythic and romantic hero. The extent to which Nin\u27s characters depart from society, undergo an inner initiation period, and renew their relationships with the larger human community is discussed. While similarities between Nin\u27s quest narrative and the traditional quest tale are demonstrated, differences are also illustrated. Nin\u27s presentation of a psychic, female rendition of the classic male quest is emphasized. In each of the five novels, the emotional nature of the adventures of the questing heroines is contrasted with the physical character of the exploits of the hero of the typical quest tale. The intended outcome of this reader\u27s guide through Anais Nin\u27s Cities of the Interior is a clearer understanding and better appreciation of the author\u27s undervalued fictional achievement. In turn, familiarity with Nin\u27s novels contributes to dispelling the mistaken notion that the author\u27s outlook is solipsistic and affirms her belief in the necessity of establishing a meaningful interaction between self and society. This study of Cities of the Interior is an offer of assistance to the reader who wishes to embark with Nin and her heroines on a descent into the interior cities--a positive, intuitive quest that eventuates in loving inclusion of others
La démarche réflexive au cœur d'un portfolio à visée certificative
No full textDans le cadre d’un certificat en management public, visant à former les futursmandataires des institutions publics, organisé conjointement par toutes les universités belges francophones, les participants rédigent un portfolio individuel (Van Nieuwenhoven, 2010) prenant appui sur une démarche réflexive (Schön, 1994). A l’entame de cette écriture, la majorité des participants découvraient la notion de portfolio et de démarche réflexive. Ils ont exprimé des craintes et avaient le sentiment de devoir « se mettre à nu » au travers de cet exercice. En outre, ces inquiétudes s’ancraient dans un contexte en tension (Romainville et Fischer, 2020) vu l’utilisation de ce portfolio comme outil de certification de la formation.Cette communication investigue les représentations en présence chez les participants à l’entame de la démarche portfolio. Tout en proposant des éléments concernant le vécu de l’accompagnement mené dans un contexte en tension entre développement professionnel et évaluation. Ce travail d’écriture ayant été accompagné par des formateurs
Transfert et identité professionnelle, deux vecteurs de professionnalisation.
No full textIl est fréquent de considérer la formation continue comme un facteur de professionnalisation et un moteur de développement professionnel. Le transfert des apprentissages de la formation vers le terrain apparait dès lors comme un élément central, incontournable. Beaucoup d’ouvrages ont analysé les conditions organisationnelles et pédagogiques favorables à celui-ci, dans une perspective de développement de la compétitivité des organisations. Nous choisissons un autre point de vue, nous centrant sur la personne en formation. Nous nous interrogeons sur son développement professionnel, défini comme un accroissement des compétences professionnelles mais aussi comme des modifications de l’identité professionnelle (Barbier, Wittorski, Donnay, Charlier). C’est cette relation entre transfert et identité professionnelle que nous voudrions approfondir, à travers une revue de la littérature mais aussi un recueil de données empiriques.Cet ouvrage tentera donc de faire des liens entre deux concepts généralement peu confrontés : le transfert des apprentissages et l’identité professionnelle, dans une perspective de professionnalisation. Nous dégageons plusieurs conceptions du transfert en lien avec l’évolution de la formation professionnelle des adultes et de la représentation de l’adulte sur laquelle elle se fonde.<br/
Avaliação de sistemas adesivos em dentina decídua: influência do envelhecimento na microtração e na nanoinfiltração
No full textTese (doutorado) - Universidade Federal de Santa Catarina, Centro de Ciências da Saúde. Programa de Pós-Graduação em Odontologia.Este estudo in vitro foi realizado com o objetivo de avaliar a resistência à microtração, e a nanoinfiltração de sistemas adesivos em dentina decídua, imediatamente (IM) e após seis meses (6M) do procedimento adesivo. Coroas de molares decíduos, hígidos e extraídos, foram desgastadas com papel de carbeto de silício até a granulação 600, obtendo-se superfícies oclusais planas, distribuídas em quatro grupos: Scotchbond Multi-Purpose (SMP), Single Bond (SB), Clearfil SE Bond (CSB) e Adper Prompt L-Pop (APL). Baseado nos dados obtidos pôde-se concluir que a resistência adesiva e a nanoinfiltração não foram influenciadas pelo envelhecimento e que a expressão da nanoinfiltração foi diferente entre os adesivos de condicionamento ácido total e autocondicionantes
