L’accélération et l’adoption massive des innovations technologiques ont transformé les usages et les comportements des individus à travers le monde. Les consommateurs utilisent désormais les technologies numériques pour presque tous les usages du quotidien. Le Marché est ainsi en forte évolution. D’une part, l’ensemble des industries font évoluer leurs modèles d’affaire pour tourner leurs offres vers le numérique, d’autre part celui-ci est devenu plus volatile de par l’introduction de nouveaux acteurs dits « disruptifs », entièrement tournés vers le numérique, et capables de mettre en péril n’importe quel acteur. Pour faire face à ces nouveaux enjeux les entreprises mettent en œuvre des programmes de transformation digitale. Ces derniers consistent à faire évoluer la manière de concevoir et fournir des services ou des produits, et de transformer la structure interne de l’entreprise pour la rendre plus compétitive, tout en faisant évoluer les conditions de travail des employés.Les objectifs de cette recherche sont de démontrer le rôle du capital intellectuel (ensemble des actifs immatériels d’une organisation) dans la transformation digitale des organisations et d'identifier dans quelle mesure il peut contribuer à l'évaluation de la maturité d'une organisation dans sa transformation digitale.Notre recherche se décompose en deux phases. Une première phase, descriptive, nous permet au travers d’une étude exploratoire, de décrire le rôle essentiel du capital intellectuel dans la transformation digitale des organisations.La seconde phase, prescriptive, consiste à proposer un modèle de maturité de la transformation digitale, s’appuyant sur les résultats de la précédente étude et appliqué dans une entreprise.Les apports de cette recherche sont multiples. D’une part, elle contribue à la littérature existante dans le domaine des systèmes d’information en sciences de gestion sur la transformation digitale, qui est aujourd’hui limitée et non étudiée au travers de la transformation du capital intellectuel. D’autre part, cette recherche applique différentes méthodes de recherche dont la revue systématique de la littérature, une étude qualitative et la conception d’un modèle de maturité selon l’approche design science. Enfin, cette recherche a aussi un apport pratique en proposant des solutions et des recommandations concrètes à une problématique rencontrée par la plupart des entreprises aujourd’hui / The acceleration and intensive adoption of technological innovations have changed people's behavior. Consumer’ daily activities have now fully integrated digital technologies. Thus, Markets have also been swept away by this wave of change.Organizations from all industries are changing their business models to move toward the development of digital offers. Meanwhile, the market has become more volatile because of new disruptive actors that provide digital services, are more flexible and can put any actor in danger.To face these new challenges, organizations are implementing digital transformation programs. They have the ambitions of changing the way of developing and providing goods & services, and transforming internal structure to make the organization more competitive, while enhancing people's working conditions.The objectives of this research are to demonstrate the role of intellectual capital (all intangible assets of an organization) in the organization’s digital transformation, and to identify in which extent it could contribute to the assessment of an organization’s digital transformation maturity.The research unfolds in two phases. The first phase, descriptive, allows to through an exploratory study, to describe the fundamental role of intellectual capital in the digital transformation of organizations.The second phase, prescriptive, describe the proposition of a digital transformation maturity mode, enriched by the results of the previous study and applied in a company.This research has multiple contributions. First, it strengthens to the existing literature on digital transformation, which is currently limited and not studied via the transformation of intellectual capital. Then, this research uses several research methods such as systematic literature review, a qualitative study and the design of a maturity model. Finally, it provides solutions to practitioners regarding issues shared by most of firms around the world.

The research originated out of a concern that loveLife, the world's largest HIV/AIDS youth education organisation in the world, was possibly replicating gendered inequities in its communication initiatives geared toward reducing transmission of HIV in the adolescent population. To carry out the research data was collected from three different "sites" and was analysed using discourse analysis. The approach to discourse analysis was informed by both Foucauldian and feminist theory. Furthermore, both the literature review and the primary data were informed by a social constructionist approach, in an attempt to recognise the environmental, social, structural, temporal and political impact on the constructions of AIDS, gender and sexuality by loveLife messages, staff and participants as they intersect with the lived realities of South African adolescents. All of the primary data is qualitative, and therefore, limited in scope. The research is experimental and iterative in nature and the data produced is varied. Nevertheless, it provides a useful snapshot with which to begin an examination of loveLife's production of knowledge and values. The data sites included: loveLife's second major print media campaign; interviews with loveLife staff and their volunteer youth corps, known as "groundBREAKERS"; and a focus group with participants at a loveLife youth centre. The print campaign included a series of five billboard advertisements and produced the most static of all the data examined. The interviews were conducted with five loveLife staff and four groundBREAKERS at loveLife's head office in Johannesburg and at a loveLife youth centre in Langa. Finally, the focus group consisted of three young men and two young women between the ages of 14-18 and was also conducted at the youth centre in Langa. The findings show that loveLife's constructions of gender are both narrow and problematic and often lose relevance when intersecting with the target audience as represented by the focus group. The findings also show that through its chosen strategy to promote loveLife as a brand, loveLife is producing a discourses that both homogenises its target audience and shifts the focus of the organisation away from transforming behaviour change as it relates to sex, sexuality and gender relations in an attempt to curb HIV transmission. Lastly, the findings also reveal that loveLife assumes that sexual choice is universally available to all South Africans. However, because this assumption does not reflect the lived realities of South African youth, particularly the realities of young women, loveLife ignores, and consequently, further replicates existing gendered inequities.

Note:

The dynamic precipitation of ferrite during austenite deformation above the Ae3 temperature, was first reported by Yada et al. in the 1980s. These observations were later confirmed for a wide range of steel compositions and processing conditions. The aim of this work is to clarify the mechanism by which ferrite formation takes place above the Ae3 temperature. To that end, a simple model for ferrite growth as a result of the movement of disconnections under applied stress is established. This motion, opposed by the back stress, increases the Gibbs energy as a result of deformation of ferrite above Ae3. Preliminary calculation suggests that the dynamic transformation is possible near the Ae3 temperature for large stress. The results are discussed in terms of experiments using a deformation dilatometer. / Thesis / Master of Applied Science (MASc)

The purpose of this study was two-fold. The first objective was to determine if Saccharomyces cerevisiae is a useful system for investigating the expression of T-DNA (it takes several months to obtain sufficient bacteria-free transformed plant tissue to investigate T-DNA transcription). A short fragment of T-DNA carrying T-DNA gene 7 was cloned into a yeast plasmid in an attempt to investigate the expression of gene 7 in yeast. The second objective was to determine the significance of a heat shock related sequence identified in the 5¹ region of T-DNA gene 7. Primer extension analysis, SI nuclease mapping, and Northern hybridizations indicate that transcription of T-DNA gene 7 in yeast is different from that of transcription of gene 7 in crown gall tumors. Transcription is different because the distance between the TATA box and the transcription initiation sites must be at least 40 nucleotides in yeast. Therefore, Saccharomyces cerevisiae does not appear to be a useful system for investigating the expression of T-DNA. Crown gall tumors were subjected to a number of stress agents, including heat shock, to determine the significance of the heat shock related sequence identified in gene 7. Primer extension analyses indicate that only cadmium and mercury have a significant effect on the expression of T-DNA gene 7. Although gene 7 responds to cadmium and mercury, the increase in transcription does not appear to be heat shock or metallothionein related, indicating that another mechanism is involved in the enhanced transcription of T-DNA gene 7 in crown gall tumors. / Medicine, Faculty of / Medical Genetics, Department of / Graduate
