Construire des bibliothèques publiques pour les adolescents grâce à l’engagement communautaire : une étude de case d’une bibliothèque publique en Corée du Sud
No full textThis study investigates essential elements of public libraries for teens. Based on the community engagement model, this study adopted a case study approach with a regional central library in Seoul, South Korea. Data were collected using interviews, surveys, and meetings with the local council. Analysis of the survey with 180 teens and 60 parents was performed. Interviews with 9 teens and 10 parents and 3 local council meetings were analyzed. The study suggests improvements in services for teens in Korean public libraries. The study shows that libraries should go beyond being a space for reading and studying to become a center of connected learning.Cette étude porte sur les éléments essentiels des bibliothèques publiques pour les adolescents Sur la base du modèle d’engagement communautaire, cette étude a adopté une approche d’étude de case avec une bibliothèque centrale régionale a Séoul, en Corée du Sud. Les données ont été recueillies au moyen d’entretiens, d’enquêtes et de réunions avec le conseil local. L’analyse de l’enquête auprès de 180 adolescents et 60 parents ont été réalisées. Des entretiens avec 9 adolescents et 10 parents et 3 réunions du conseil local ont été analyses. L’étude suggère d’améliorer les services destinés aux adolescents dans les bibliothèques publiques coréennes. L’étude montre que les bibliothèques doivent aller au-delà d’un espace de lecture et d’étude pour devenir un centre d’apprentissage informel and formel connecté
D'une Servante à l'autre. Transmission et projections, de la page au petit écran
No full textIn 2017, the broadcast of the series adaptation of the dystopian novel The Handmaid's Tale (1985) allowed a wide audience to discover the name and the work of the Canadian novelist Margaret Atwood. The Handmaid's Tale had already been adapted for the big screen in 1990. Shunned by the public, not much appreciated by the critics, Volker Schlöndorff's film was quickly forgotten, while Bruce Miller's series continues to attract the favor of its many commentators. This article will try to understand this difference in appreciation by asking whether the format of the television series would be better able to capture the themes and literary problems posed by Atwood's novel from the audiovisual language that is its own.En 2017, la diffusion de l’adaptation en série de du roman dystopique La Servante écarlate (The Handmaid’s Tale, 1985) a permis à un large public de découvrir le nom et l’œuvre de la romancière canadienne Margaret Atwood. Or, cet ouvrage avait déjà fait l’objet d’une adaptation sur le grand écran et ce, dès 1990. Boudé par les spectateurs, peu apprécié par la critique, le film de Volker Schlöndorff a rapidement été oublié, tandis que la série de Bruce Miller continue de s’attirer les faveurs de ses nombreux commentateurs. Le présent article cherchera à comprendre cette différence d’appréciation en se demandant si le format de la série télévisée serait plus à même de cerner les thématiques et les problématiques littéraires posées par le roman de Atwood à partir du langage audiovisuel qui est le sien
Dynamic functional connectivity in the brain during rhythm listening: An exploratory fMRI study
No full textDespite decades of research, little is known about the neural circuits involved in rhythm and beat perception. Previous studies suggest the involvement of the striatum and supplementary motor cortex in a cortico-subcortical network activated by rhythms with a regular beat. However, assumptions that functional connectivity does not change during rhythm perception may be unwarranted due to the brain's dynamic nature. To address this, we used functional magnetic resonance imaging to study dynamic changes in functional connectivity. Participants underwent three five-minute scans; they listened to rhythms with a beat, rhythms without a beat, and silence. We statically and dynamically compared the cortico-subcortical network involving the superior temporal gyrus, supplementary motor area, and putamen between the three scanning conditions. Our results supported the idea of reorganization in brain networks during different listening states, with changes in functional connectivity seen at various time points of specific conditions. Given that the study was exploratory, we discuss how our findings contribute to the existing literature and suggest ways to advance future research
The role of social support in developing recovery capital
No full textThe substance abuse literature suggests that social support is a key component of recovery from substance use disorders (SUD). However, the mechanisms underlying this relationship are not well understood. The objective of this paper is to address this gap in our current understanding by employing Cloud and Granfield’s (2008) recovery capital framework, which consists of four subtypes of capital: physical, social, human, and cultural. The contribution of social support to each subtype of recovery capital is considered individually, in order to examine how social support contributes to one’s overall recovery capital. Differences in the amount of social support experienced by various sociodemographic groups are also considered, with a focus on deficits in social support for women, young people, and racial minorities. Areas that require further research development are discussed. This review yields two practical implications for SUD treatment: the need for online mutual-help groups, and the inclusion of interpersonal skills training and education in SUD treatment. 
Community Stakeholders’ Perceptions of the Impact of the Coronavirus Pandemic on Homelessness in Canada
No full textHomelessness was already a well-known risk factor contributing to premature death, morbidity, mental illness, and substance use disorder. The coronavirus disease for 2019 (COVID-19) pandemic has amplified disparities in Canada’s public health system, disproportionately impacting people experiencing homelessness. The present study aimed to investigate the impact of the COVID-19 pandemic on the homelessness situation in Canada from community stakeholders’ perceptions. The study used qualitative research approaches underlain by focused ethnography tenets. The sample includes 200 service providers from 28 communities across Canada (at least one site in each province and territory) to participate in virtual focus groups. Data analysis followed a four-step ethnographic approach for thematic analysis in qualitative research. Six main themes emerged: (a) system changes precipitated by the COVID-19 pandemic; (b) personal changes in life circumstances; (c) previous strategies no longer working; (e) opportunities; (d) some things getting better; (f) an overall increase in first time and recurrent homelessness in Canada. The study findings underscored mechanisms required to help ‘tip the scale’ in affording people experiencing homelessness the opportunity to avoid or exit homelessness
Laurent Series and Puiseux Series in Maple
No full textLet K be an algebraically closed field of characteristic zero. The field of fractions of the ring of formal multivariate power series over K, is called the field of formal multivariate Laurent series. In this document, we follow the ideas introduced by Monforte and Kauers in their paper Formal Laurent Series in Several Variables. Our objective is to report on a first implementation of formal multivariate Laurent series inside of Maple, and explain the challenges we had to overcome. In order to accomplish this goal, we make use of the already existing MultitivariatePowerSeries package, and its lazy evaluation scheme. In particular, we expose our ideas for adding and multiplying Laurent series with support inside different cones, where the support of a Laurent series is the set of all exponents of all non-zero monomials of our series. We also describe our biggest challenge, how to invert a Laurent series. Unfortunately, this problem cannot be completely solved in a lazy evaluation context. We describe some situations where we can solve the problem completely; our approach for the cases that fall outside of these situations; and how we let the user customize this approach, trading off between speed and the likelihood of an incorrect result.
The algebraic closure of the field of formal multivariate Laurent series is call the field of formal multivariate Puiseux series. As an extension of our current work, we also present our ideas for an implementation of a multivariate Puiseux series object inside of Maple

“Silver is for Monsters” – Des livres aux jeux, étude de la translation d’une matière escrimale vers le média audiovisuel dans la série The Witcher (Netflix)
No full textFencing, and more generally speaking martial representations are at the core of The Witcher universe. It is embedded in Geralt of Rivia, a monster hunter and the story’s main character who always carries his sword with him, and therefore, through him, fencing plays a major role in this universe as it feeds its narration and characterization with the fights lead by the character. The Witcher is also a transmedial universe, who was given birth by the writer Andrzej Sapkowski and recognised for its video game adaptations made by CD Projekt. In that prospect, fencing supposedly constitutes a pillar in the project of TV show adaptation by Lauren Schmidt Hissrich for Netflix. This article offers a study concerning how fencing representations appear as an element contributing to the coherence of this adaptation, considering the preexisting transmedial works. It takes into account the features of TV shows (budget, CGI, scenic props…), questions the specificities implied, such as biomechanics and actors’ knowledge, and also how fights are written compared to books and games. From a compared literature and ethnoscenology perspective, this crossed study offers to identify the series’ fencing aesthetic and its relation to the universe’s transmedial web. Doing so, it looks at the worldbuilding dynamics at work, and the relation between Primary and Secondary World.L’escrime et plus généralement l’imaginaire martial sont au cœur de l’univers The Witcher. Incarnée par Geralt de Riv, chasseur de monstres et protagoniste de l’œuvre qui ne se départit jamais de son épée, elle tient par son biais une place charnière au sein de l’univers, qui nourrit sa narration des affrontements menés par le personnage. The Witcher est également un univers transmédial, né de la plume d’Andrzej Sapkowski et reconnu pour son adaptation vidéoludique par CD Projekt. Aussi, lorsque Lauren Schmidt Hissrich se lance dans un projet d’adaptation sérielle pour Netflix, l’escrime se situe supposément comme un pilier de ce processus. Cet article se propose d’étudier comment l’imaginaire escrimal s’impose comme un élément de cohérence de cette adaptation, en regard des œuvres transmédiales lui préexistant. Il s’interroge sur les spécificités que le média sériel implique, telles que la biomécanique ou les compétences des acteur·rice·s, ainsi que la manière dont il chorégraphie des combats en parallèle des livres et jeux. À cheval entre la littérature comparée et l’ethnoscénologie, cette étude croisée propose ainsi d’identifier l’esthétique escrimale de la série et son rapport au tissu transmédial de l’univers qu’elle dépeint, en se penchant notamment sur les dynamiques de worldbuilding et les rapports entre Monde Primaire et Monde Secondaire
