Barbosa, de Souza Held. "Analyse bibliométrique de la contribution des postdoctorants canadiens à l’avancement des connaissances." Thèse, 2014. http://hdl.handle.net/1866/11859.
Full textCanadian postdoc fellows represent an increasingly important group of researchers that faces various problems resulting from deficiencies on the higher education system. Additionally, their contribution to the research system remains largely unknown. This study presents a bibliometric analysis of the scientific production of postdoctoral fellows funded by the Canadian and Quebec granting agencies, whose grant application was submitted between 2004 and 2008 (N = 3,454). The results show that the scientific impact, as well as the number of papers authored by postdocs is equal or higher than the ones of PhD students and of faculty members from Québec. We also observe that postdocs who completed their training in the United States obtain higher productivity and impact indicators. This study is the first of its kind in Canada and helps identify the contribution of postdocs to the advancement of knowledge.
Pichot, Alizée. "Transmédia Storytelling à l’ère de la convergence : processus de réception et mythe médiatique." Thèse, 2016. http://hdl.handle.net/1866/18676.
Full textThe alternate reality game Why So Serious ? lies at the heart of a transmedia storytelling strategy created for the promotion of the movie The Dark Knight (2008) by Christopher Nolan. This game is deeply rooted in an era of convergence in which the distinction between production and reception of media messages is blurred. Different players’ practices illustrate specific modes of reception that, linked to the emergence of a plot with multiple threads, indicate the emergence of new communicational and narrative issues. This thesis examines those specific processes of reception and their relationship to the appearance of a mythological message in which the fictional world of Batman is recentered on the character of the Joker. Through the articulation of a netnography of the game’s official forum, Unfiction, visual semiotic analysis and Barthesian mythological analysis, it was possible to schematically build a communication circuit within which the messages produced by both the cultural industries and the game players evolve. This study contributes to and contributes to an understanding of active users’ power in this transmedia phenomenon. Furthermore, it highlights the users’ ability to generate a brand new message, thus mythological, whose significance is nourished by diverse sources, from the nature of medium itself, to the interpretation of the fictional universe within the experience itself.

Full textThis study explores the usage of open access (OA) and delayed OA journals in the social sciences and humanities hosted by the journal platform Érudit. Relying on Érudit’s download data, the goals of the study are: 1) to describe the usage of scholarly articles, 2) to examine download patterns of national and international users, and 3) to analyze the effect of OA policies on journal download rates. The study is based on an analysis of 39,437,659 downloads, which were extracted from 999,367,190 HTTP requests stored in Érudit’s log files between 2010 and 2015. The results show that the majority of users came from Quebec, France and other French-speaking countries, and that most users access articles through Google. Download patterns varied between countries: although articles were most frequently accessed during working hours, US users were more active in the evening, at night and during weekends than Canadian and French users. The study also demonstrates a clear OA advantage, as freely available articles were downloaded more frequently than delayed OA articles affected by an embargo, and downloads per article increased substantially after embargos ended. This effect was less pronounced for Canadian users, who often have access to Érudit journals via institutional subscriptions and are thus not affected by the embargo periods. The results show the positive effect of OA on knowledge dissemination in Canada as well as internationally, and emphasize the importance of national journals in the social sciences and humanities.
Leon, Ayala Sandra Caterine. "Les personnes âgées face au défi d'utilisation des nouvelles technologies : étude de l’utilisabilité des interfaces de téléphones portables." Thèse, 2010. http://hdl.handle.net/1866/4736.
Full textTechnological progress and the growing aging population are two major trends of the last decade. The ubiquitous proliferation of mobile communication devices during this period has significantly altered people’s communication habits. The constantly changing mobile phones, their increasing features, the numerous icon designs, the variety of user interfaces and its complex navigation require nowadays not only more time for adaptation and learning but also a significant cognitive effort. Information technology and communication (ICT) have become essential tools of modern life. For seniors, this constantly mutating universe with its new digital devices makes information accessible to many thus contributing to a generational divide. The lack of reference and support and the physical or cognitive impairment that some people often develop while aging makes the use of such products very difficult. Both, a physically and cognitively accessible system becomes a real necessity in our modern society since it could help seniors live more autonomously and« connected ». This research aims to identify the challenges related to mobile phone use and reveal specific problems that older people encounter. The study focuses on the population that is little familiar with these devices especially since communication technologies seem aimed at the younger generations and professionnels. Through qualitative research seniors’ usage pattern will be studied allowing us not only to establish different user profiles with respect to ICT but also to better understand the challenges related to the perception, comprehension and manipulation of mobile phone user interfaces.

Full textWho does what in a scientific research team? This work proposes to define the roles of each author with an original methodology. The order of the authors is a useful indicator of the relative importance of each of the co-authors, but it does not reveal the precise nature of their respective role. Our research shows that using statements of contributions from scientific articles for bibliometric purposes is possible, even on a large scale. Our results show that there are differences in the contributions to scientific articles and these differences also apply to the distribution of work among research teams by gender.

Full textThe discovery of the death of my great-grandparents, gassed in 1943 at the Auschwitz concentration camp in Poland, triggered a frantic search for archives and raised several questions. The genealogy proceeds from a research of kinship, of filiation which links us to a context of society and the archives, formerly secret and devoted to experts (historians and researchers), know with these users a revival of informational but also emotional interest, both at the concrete (material) and virtual (digital) levels. Jewish genealogy is on the fringes of this movement because it often testifies to another psychological and sometimes physiological need, that of filling a "gaping hole" that several migrations, pogroms and a "recent" genocide have dug. In this context, we wondered what the importance of archives could be (in a traumatic context) in Jewish genealogy and their emotional and identity impacts. To answer these research questions, we visited genealogical routes in two organizations: the Jewish Genealogy Circle in Paris and the Jewish Genealogical Society of Montreal. The portraits we have drawn differ. Parisians are more attached to the original archives (especially in the context of the Shoah) and they do not hesitate to share them; Montrealers are more fond of digital archives (especially in the context of immigration) and they favor information rather than medium. However all participants agree on one point: these archives, in addition to enabling better understanding and self-building for some, have consequences for their lives. Undoubtedly, this research of archives on their Jewish ancestors responded (partially?) to a need for singularity. A future study could characterize the archive which marks so much and the particularity of the effects it produces on those who seek it.
Bussière-Lavallée, Véronique. "Du modèle du cercle magique à celui de la place du joueur : un apport de l’esthétique de la réception au design de jeux vidéo." Thèse, 2013. http://hdl.handle.net/1866/10973.
Full textThis thesis proposes a consideration of models that allow one to better understand and develop the aesthetic experience of a video game. Such models reflect different ideals of the player’s position. Since we approach it through a reflection on the model of the “magic circle”, play is often understood to be a unilateral act of entering, via the imagination a world foreign to the real world - where any penalty or exit marks the end of the game. Looked at this way, the designer’s role is therefore to place and maintain the player in the virtual world, making him feel immersed and present therein. However, as evidenced by those critics who speak out against the model of the magic circle, other strategies to put the player in place need to be distinguished and defined in order to facilitate the analysis and design of video games. Given this model, deemed to be restrictive, what we propose is to use some typological and methodological tools of reception aesthetics in art history in order to build a more inclusive model of the "player's place", the validity of which is tested by analysing the video game God of War III (2010).
Dione, Bernard. "L’accommodation des valeurs professionnelles aux valeurs culturelles chez les bibliothécaires universitaires sénégalais." Thèse, 2012. http://hdl.handle.net/1866/8778.
Full textA profession basically includes two components: scientific skills and professional values, which are the guidelines of professionals’ daily demeanor. The library profession is based on values like the preservation of humanity cultural heritage, a fair access to knowledge, intellectual freedom, confidentiality and the protection library users’ private lives, professional neutrality, tolerance etc. In Senegal as well as in the other African countries, libraries are, on the whole, legacies of colonialism. The values of library science were designed in a western perspective. This profession value system may sometimes conflict with the Senegalese librarians’ cultural value systems. However, very little is known on ways Senegalese professionals cope with these two value systems. This present research will describe and explore the interactive co-existence and adaptation of professional values within the cultural value system of Senegalese academic librarians. It seeks to answer the following research questions: (1) what is the Senegalese academic librarians’ dominant cultural value system? (2) How do Senegalese academic librarians prioritize their professional values? (3) How do Senegalese academic librarians adapt their professional values to cultural values? This exploratory and descriptive analysis combines a mixed methodology approach: Two types of data collecting methods have been used: a questionnaire based on interviews and on Schwartz’s Portrait Values Questionnaire (PVQ) (Schwartz, 2006) The findings highlight the fact that, on the cultural level, Senegalese academic librarians essentially emphasize, in the value system, the interests of the social group they belong to, the respect of social order and adoption of normative behavior in order to facilitate their relationships with the other group members. The values favor a strong integration of the individual into a group but do not encourage an action and thought autonomy which may destroy social harmony. On the professional level, they regard access to information, preservation and conservation of heritage and the denial of all sorts of discriminations as essential professional values. As professional values conflict with cultural norms, Senegalese academic librarians often seek a compromise, a balanced position to make decision which does not basically question their cultural values. When a compromise is impossible, the final decision is made in favour of cultural values. On the theoretical level, this research confirms the theory of a value system predominance rooted in Schwartz’ perspective of the “continuity/self-transcendence” (Schwartz, 2006, 1992). In his system, the dominant values are universalism, benevolence, tradition, conformity and security. These values favor the individual’s integration into a group, solidarity and family security and the refusal to undertake actions which may endanger group harmony. On the practical level, this research displays the necessity to reinforce professional socialization which includes ethics and values in the training of Senegalese academic librarians.
Singh, Harsh Jot. "Prediction of the transaction confirmation time in Ethereum Blockchain." Thèse, 2019. http://hdl.handle.net/1866/23790.
Full textBlockchain offers a decentralized, immutable, transparent system of records. It offers a peer-to-peer network of nodes with no centralised governing entity making it ‘unhackable’ and therefore, more secure than the traditional paper based or centralised system of records like banks etc. While there are certain advantages to the paper based recording approach, it does not work well with digital relationships where the data is in constant flux. Unlike traditional channels, governed by centralized entities, blockchain offers its users a certain level of anonymity by providing capabilities to interact without disclosing their personal identities and allows them to build trust without a third-party governing entity. Due to the aforementioned characteristics of blockchain, more and more users around the globe are inclined towards making a digital transaction via blockchain than via rudimentary channels. Therefore, there is a dire need for us to gain insight on how these transactions are processed by the blockchain and how much time it may take for a peer to confirm a transaction and add it to the blockchain network. In this thesis, we aim to introduce a novel approach that would allow one to estimate the time (in block time or otherwise) it would take for Ethereum Blockchain to accept and confirm a transaction to a block using machine learning. We explore two of the most fundamental machine learning approaches, i.e., Classification and Regression in order to determine which of the two would be more accurate to make confirmation time prediction in the Ethereum blockchain. More specifically, we explore Naïve Bayes classifier, Random Forest classifier and Multilayer Perceptron classifier for the classification approach. Since most transactions in the network are confirmed well within the average confirmation time of two block confirmations or 15 seconds, we also discuss ways to tackle the skewed dataset problem encountered in case of the classification approach. We also aim to compare the predictive accuracy of two machine learning regression models- Random Forest Regressor and Multilayer Perceptron against previously proposed statistical regression models under a set evaluation criterion; the objective is to determine whether machine learning offers a more accurate predictive model than conventional statistical models.
