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.

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 textInformation retrieval is generally concerned with answering questions such as: is this document relevant to this query? How similar are two queries or two documents? How query and document similarity can be used to enhance relevance estimation? In order to answer these questions, it is necessary to access computational representations of documents and queries. For example, similarities between documents and queries may correspond to a distance or a divergence defined on the representation space. It is generally assumed that the quality of the representation has a direct impact on the bias with respect to the true similarity, estimated by means of human intervention. Building useful representations for documents and queries has always been central to information retrieval research. The goal of this thesis is to provide new ways of estimating such representations and the relevance relationship between them. We present four articles that have been published in international conferences and one published in an information retrieval evaluation forum. The first two articles can be categorized as feature engineering approaches, which transduce a priori knowledge about the domain into the features of the representation. We present a novel retrieval model that compares favorably to existing models in terms of both theoretical originality and experimental effectiveness. The remaining two articles mark a significant change in our vision and originate from the widespread interest in deep learning research that took place during the time they were written. Therefore, they naturally belong to the category of representation learning approaches, also known as feature learning. Differently from previous approaches, the learning model discovers alone the most important features for the task at hand, given a considerable amount of labeled data. We propose to model the semantic relationships between documents and queries and between queries themselves. The models presented have also shown improved effectiveness on standard test collections. These last articles are amongst the first applications of representation learning with neural networks for information retrieval. This series of research leads to the following observation: future improvements of information retrieval effectiveness has to rely on representation learning techniques instead of manually defining the representation space.

Full textIn Western and Eastern Antiquity, names of well-know people were associated with methods and tools for worldview transformation and personality metamorphosis. Since the 1920s, we are witnessing the same phenomenon through the emergence of personal development celebrities. Today the personal development field is a thriving industry. The popularity, attractiveness and influence these leaders can have over others is an important question, at least as much as the criticism and heated debates they raise. Intrigued by this phenomenon, and questioning her own practice as a professional coach, this study adopts a constitutive approach to organizational communication to better understand the communication practices by which the authority of such leaders is accomplished in and through interactions. This research shows the presence of processes already identified in the literature for their role in the production and reproduction of authority in interactions such as presentification, invocation and authoring. Two new communication practices also emerged from the data and have been identified as self-distinction and distance management. Access to an organization led by a personal development leader is rare, it represents a unique and rich organizational context and opens up many avenues for future research.

Full textAbstract This thesis addresses the appropriation of the Internet and of multimedia in the university population of French-speaking Africa, in the year 2001. It deals with six sub-Saharan countries: Benin and Burkina Faso, Cameroon, Ivory Coast, Mali and Togo. The research is specifically interested in the inventory of demographic research centers in sub-Saharan French-speaking Africa and the investigation with the universities of Yaoundé II and Douala in Cameroon. The question of access and use is central to our approach. Articulated as a research question, the focus is as follows: "In a context dominated by the representations of the ICTs as symbols of modernity and ways of integrating the world economy, what are the modalities of appropriation of these technologies by academics within postsecondary institutions of teaching and research in Africa considered in this study?" Two theoretical approaches were adopted to deal with the empirical data : theories of development tied to the (new) media and the sociology of technological innovations. Rooted in the thought of the Enlightenment, completed and refined by the evolutionist approaches inspired by Spencer, Parsonian functionalism and the political economy centered on the thought of W.W. Rostow, theories of development have made much use of theories of the communication in order to achieve their objectives. Even as the crisis of Western modernity threatens to delegitimize these paradigms, the emergent technologies give them a new lease on life: in continuity of the thought of Auguste Comte, development is henceforth thought in terms of integration within a new social structure, the information society. This new eschatological promise and this faith in technology as the factor of integration within society and the network economy animate all the projects undertaken on the continent, whether it is the NEPAD, the Digital Solidarity Fund, the $100 Computer Project for Deprived Children or the Pan-African project of satellite sideboard, the RASCOM. The second part of our theoretical framework is centered on the sociology of technical innovations. We make use of the socio-political approach to usage developed by Vedel and Vitalis to re-introduce critical reason into the debate on the development of the African continent, with a view to showing how political prerogatives at the State-level still have their place, if we want to develop digital resources that satisfy social demands and respond not only to demands deemed solvent and essentially arising out of urban areas. By refusing the technical determinism so current in thinking about development, we would like to show that the future of technology is not inscribed in its essence, like a shadowy presence, but that human action, notably political action, can reorient the trajectory of technological innovation in the direction of responding to the aspirations of citizens. Methodologically, our approach combines quantitative methods and qualitative methods. The former will allow us to measure the presence of the Internet and multimedia in the environment of those concerned. The latter will help us to grasp the representations developed by the users in contact with these tools. Within a socio-constructivist perspective, these discourses are constitutive of these technologies, inasmuch as they are so many modalities of appropriation, of the social construction of usage. Ultimately, the integration of the technical language specific to these multimedia tools into the every day language of the users signals the last stage of this appropriation. Through this research, it became evident that few users utilize audiovisual technologies in a professional context. As for the Internet and multimedia tools, their presence and their use remain limited, physical access not yet being guaranteed to all the respondents of the study. The Internet, while creating large expectations, also remains largely inaccessible in a professional context, the majority of the users making use of public spaces such as cyber-cafes to mitigate the lack of resources within their own institutions. As far as representations go, they remain still widely dependent on the dominant political and institutional discourses, according to which the future will be digital or will not be. The thesis, however, goes beyond this data in order to draw up the current digital map of the continent, by integrating within the technological landscape the phenomenal rise of mobile cellular technology. It appeared to us that the Internet, the availability of which on the continent has been modest at best, could widely take advantage of the emergence on the continent of the mobile culture, which facilitates in particular the convergence between netbooks and mobile telephones (smartphones).

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.

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.

Full textThis thesis operates mainly on two levels: one is ethnographical, the other is communicationnal. I explore the curious case of North American jungle backyards in which « used-to-be-wild » animals are experiencing « almost-domesticated » existences while their daily lives are merged with that of Homo sapiens. As pets, guinea pigs or postnatural totems, these pioneer organisms not only feed the third most important black market in the world, they also blur our traditional zoological and philosophical apparatus (often driven by dichotomies between nature/culture, human/nonhuman, prey/predator, dominant/dominated, transmitter/receiver). In 2011, I traveled 16 000 miles all around the continent to explore some of these contemporary humanimal modalities. Hence, I examine important transpecific aspects of these modified ecological landscapes, in which known living organisms experience unknown reorganizations of life. In a Simondonian perspective, I reconceptualize animality and communication activities in order to readdress, along with the question of the animal, individuation processes and their inherent indetermination qualities – the kind, yet unseen, that contemporary jungle backyards silently nurture. At a time when animal rights and bioethics are regularly at stake (and indeed a serious preoccupation for societies that strive to leave behind medieval practices, but also attempt to cope with their biotechnological becomings), jungle backyards provide an original ethological dataset based not only on what an animal is or should be, but rather on what real animal existences actually consist of. In that respect, I offer firsthand material that may help to better navigate our common Ark, possibly facing a new environmental flood. Instead of considering animals from a reductive substancialist point of view or from a strict hylemorphic perspective, focusing on matters of form or forms of matter, I concentrate on movements that give form to matter and matter to form. I then suggest that animality, more than a simple collection of mere attributes or even a basic manifestation of an elaborate biochemical complex, constitutes an enmeshment constantly in motion made of transductive relationalities. Here, biomedia are not considered the latest bourgeon of our technological modernity, slowly shifting from inorganic materialities to organic potentialities, but rather an ancient deviation of natural forces (too quickly restricted to domestication). Instead teckné and anima operate jointly and disparately to propel what I call aniculture and which I consider to be not only a part of our anthropogenic processes, but also a mutagenic pool of differentialities from which humanity constantly draws in order to reinvent itself. Then, along with a specific textual mode of organization (as transpecific as its topic), writing is here even envisaged as another possible expression of animality, maybe even a powerful re-intensification. Because our traditional dealings with animals have always been inseparable from our becomings, the (yet untold) ways we are now dealing with some of our ex-predators and preys reveal a great deal about our postnatural futures and that “animal-medium” we all inhabit. In fact, jungle backyards are less denaturalized places than renaturalized spaces in which animals demonstrate not only adaptive responses to selective pressures but initiate creative processes at a number of levels from which fertile lines of thought can eventually stem.

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.
