Text in English / In South Africa, retention of newly qualified professional nurses in public health institutions upon completion of their year of compulsory remunerated community service remains a challenge that exacerbates the shortage of professional nurses in these institutions. The literature indicates that many newly qualified professional nurses leave the public health institutions due to lack of professional development support and heavy workloads while they are still finding their feet. A mixed-methods design of concurrent triangulation approach was used to answer the question: How are the newly qualified professional nurses supported in terms of induction and professional development during community service in South Africa? Triangulation was achieved by using both quantitative and qualitative methods. Induction/orientation documents from public health institutions were analysed using a checklist. A survey questionnaire with mixed quantitative closed items (1–43) and qualitative open-ended questions (43–46) was sent to newly qualified professional nurses who had recently completed community service. Focus groups held with operational nurse managers and individual interviews with coordinators of community service for nurses yielded rich qualitative data. Descriptive and inferential statistics were used to describe and synthesise data. The qualitative findings confirmed the quantitative findings. Findings were lack of professional development support in some public health institutions, informal, non-comprehensive support where given, shortage of experienced professional nurses, reluctance by some professional nurses and operational nurse managers to supervise newly qualified nurses, and increased workload due to the shortage of experienced professional nurses in the public health institutions. Inadequate clinical skills, poor discipline and lack of professionalism in the newly qualified professional nurses also played a part. Respondents suggested constructive recommendations for the induction and professional development support of the newly qualified professional nurses, and these were incorporated in the recommended guidelines for the induction and professional development support of newly qualified professional nurses during community service. / Health Studies / D.

Vegetative species diversity is under threat from environmental pressures, particularly climate change. As the impacts of climate change vary from place to place, response of vegetative species diversity to a changing climate also vary depending on geographical location. The response of vegetative species diversity under dry conditions in Zimbabwe is not well known. This study assessed the impact of climate change on vegetative species diversity under semiarid conditions of Masvingo province in Zimbabwe. This was achieved by determining climate change trends over a period of forty years (1974-2014), and examining the relationship between vegetative species diversity and spatially interpolated climate data. The absence of historical diversity data prompted the use of remote sensing to enable the assessment of spatial and temporal changes. Thus, the Normalised difference vegetation index (NDVI) was used to assess vegetative species diversity changes after establishing a positive relationship between species diversity and NDVI. The mixed methods research design was used as the strategy of inquiry. The non-aligned block sampling design was used as the sampling framework from which 198 sampling points were identified. Meteorological data obtained from Zimbabwe Meteorological Services Department (ZMSD) and the National Climate Data Centre (NCDC) were used for climate change analysis. Data collected through image analysis, direct observations, questionnaire surveys and interviews were used to assess the impact of climate change on vegetative species diversity. Results indicate that all temperature and precipitation variables have significant (p<0.05) trends over the period under study. However, the trend for seasonal total precipitation was not significant but declining. The significant trends indicate that climate change occurred over the period under study. 93% of the respondents confirmed having experienced the climate change phenomenon. Results also show a significant relationship between climate elements (precipitation and temperature) and vegetative species diversity represented by Shannon Weaver Index (H). More so, there is a positive relationship between NDVI and H. Vegetative species diversity represented by NDVI decreased over the period under review. The results indicate that climate change has contributed to the decrease of vegetative species diversity in Masvingo province, thus it is a force behind many other factors contributing to biodiversity loss. / College of Agriculture and Environmental Sciences / Ph.

The phenomenon of business value dissipation in mature organisations as an unintended by-product of the adoption and use of information systems has been a highly debated topic in the corporate boardroom awakening the interest of practitioners and academics alike. Much of the discourse tends to focus on the inability of organisations to unlock and realise the intended benefits to be harvested through large information systems investments. While the business case for investing in large technology programmes has been thoroughly investigated, the human agent that causes value erosion through his interaction with information systems (IS), has not received the studied attention it deserves. This study examines the use of technology in organisations by considering the dichotomy inherent in IS where its introduction for the purposes of creating new or sustaining existing business value subsequently also inadvertently dissipates value. The study proceeds to investigate the root people-induced causes resulting in the unintentional dissipation of value and presents an empirically validated model suggesting that human agents do not only create value for organisations through their use of IS, but at the same time, deliberately or inadvertently, dissipate value. The root people-induced causes resulting in the unintentional dissipation of value is delineated within a Theoretical Technology Value Framework that is constructed from a review of the extant literature, and delineates the overall unintentional value destroying causes and effects of IS on organisations. The Theoretical Technology Value Framework is forthwith applied as a basis for the development of a set of questions to support both qualitative and quantitative investigations from which an Archetypical Technology Value Model was derived. Finally, an Archetypical Technology Value Model is presented as a benchmark and basis to identify, investigate, mitigate and minimise or eliminate the unintentional value destroying effects of IS on Information Technology driven organisations. The study concludes with implications for both theory and practice and suggestions on how value erosion through the activities of the human agent may be identified, modeled and mitigated. Ultimately, recommendations are offered towards the crafting of more effective IS. / School of Computing / Ph. D. (Information Systems)

The Digital Doorway (DD) project provides computing infrastructure in impoverished communities in South Africa. DD terminals offer opportunities for unassisted- and peerassisted learning of basic computer skills, and varying computing activities ranging from entertainment, to independent research. This study addresses software application usage, and how it relates to user demographics (age and gender) and location, in order to better understand both the user base, and the nature and extent of DD interactions. A mixed-methods approach is employed, involving log-files, interviews, questionnaires, and naturalistic observation; to build up a holistic picture of application usage and user behaviour at selected sites. Important issues with respect to ICT for Education and Development in the DD context, are addressed. Analysis of the data indicates notable trends, and relationships between age, gender, location, and application usage. User behaviour and environmental effects on usage are discussed, and recommendations provided for future DDs and similar initiatives. / Computing / M. Tech. (Information Technology)

Global and South African business challenges necessitate an increased focus on the need for effective leadership. The leaders of South African public listed organisations need to investigate new business solutions to enhance and sustain organisational effectiveness. Public listed South African organisations on the Johannesburg Stock Exchange (JSE) were selected as the organisation type for this study. This study was motivated by the need for public listed South African organisations to explore organisational leadership as a means to assist in differentiating their organisations from competitors, thereby enhancing organisational competitiveness. The primary research objective of this study was to investigate and establish an organisational leadership brand concept model for public listed South African organisations. The discussion of the literature covered the global and South African business context, the concepts of the nature of organisational leadership, brand and organisational leadership brand, and emminated in an exploratory conceptualisation of organisational leadership brand for public listed South African organisations. The pragmatic paradigm was used as the foundation of this study. The study adopted an exploratory, sequential mixed methods research approach, combining a qualitative emphasis and supportive quantitative research approach to conduct the exploratory research. The qualitative findings proposed the concepts: the nature of organisational leadership and organisational leadership brand, including stakeholders and these concepts served as the basis for designing the quantitative survey questionnaire. The quantitative results indicated reliable questionnaire items, and based on the exploratory statistical analysis of the multivariate linear regression equation, described the organisational leadership brand (OLB) concept exploratory model with the best fit. An integration of the qualitative findings and quantitative results provided the empirical support to achieve the primary research objective. The OLB concept model integrates the concepts of organisational leadership and organisational leadership brand. The study contributed across the methodological, theoretical and practical domains as follows: the nature of organisational leadership for South African public listed organisations was conceptualised; the elements comprising the concept of OLB for public listed South African organisations was described; the OLB concept model for public listed South African organisations describes the development of organisational leadership brand equity through four levels of organisational leadership brand equity development; and the OLB concept model for public listed South African organisations may assist by providing guidance for the senior leadership of organisations in establishing organisational leadership brand equity. Furthermore, the study’s research approach provides support for the use of a mixed methods research approach in the study of organisational leadership within the pragmatic context of business organisations / Industrial and Organisational Psychology / D.

La transition du milieu de soins pédiatrique au milieu adulte est un processus exigeant pour les jeunes atteints de maladies chroniques, puisqu’elle a lieu durant une période de leur vie où beaucoup de changements se produisent simultanément. N’étant pas encore tout à fait autonomes, les jeunes doivent apprendre à prendre soin d’eux-mêmes alors qu’ils se retrouvent parachutés dans un nouvel environnement, au sein d’une nouvelle équipe médicale. La diminution de l’encadrement peut en mener certains à prendre leur médication de manière erratique ou à manquer des rendez-vous. En transplantation rénale, une baisse de l’observance thérapeutique peut avoir pour conséquences des épisodes de rejet qui conduisent parfois à la perte du greffon. Pour pallier ces problèmes, deux néphrologues du CHU Sainte-Justine et une néphrologue du Centre hospitalier de l’Université de Montréal (CHUM) se sont consultées afin de mettre en place une clinique de jeunes adultes greffés du rein. Cette clinique s’adresse spécifiquement aux jeunes adultes, tant ceux ayant vécu la transition que ceux greffés à l’âge adulte. L’objectif de cette thèse est de mener l’évaluation des processus ainsi que l’évaluation des effets médicaux et psychosociaux de la clinique des jeunes (CDJ), en comparant le groupe de patients qui y sont suivis aux jeunes patients suivis à la clinique adulte régulière (CAR). Dans le premier article, qui présente l’évaluation des processus, des entrevues semi-structurées sont réalisées auprès de 10 patients de la CDJ, afin de décrire leur expérience de la clinique et d’identifier les composantes contribuant à son succès ainsi que des pistes d’amélioration du service. L’analyse thématique propose six thèmes caractérisant l’expérience des patients: (a) le soutien à l’autonomie versus la surprotection, (b) les garanties de sécurité à travers l’incertitude, (c) l’identification et le sentiment d’appartenance, (d) la complémentarité des approches entre les milieux de soins pédiatrique et adulte, (e) un environnement s’harmonisant avec le mode de vie des jeunes adultes et (f) les raisons de non-adhérence au traitement. Dans le deuxième article, qui présente l’évaluation des effets, une méthodologie mixte quantitative et qualitative est utilisée afin de mettre en contraste l’expérience de 17 patients de la CDJ avec celle de 16 patients de la CAR, de vérifier l’efficacité de la CDJ et de vérifier l’utilité de la théorie de l’auto-détermination (TAD) dans notre contexte. Les analyses quantitatives comparatives révèlent que la CDJ semble efficace surtout dans la période critique post-transition ou post-greffe en milieu adulte. Le fait d’être suivi à la CDJ semble minimiser l’incidence des complications médicales, améliorer l’adhérence au traitement et la qualité de vie physique des patients. Les analyses corrélationnelles établissent des liens entre les variables de la TAD (perception de soutien à l’autonomie, motivation autonome ou contrôlée, sentiment de compétence), l’adhérence au traitement et la qualité de vie. L’analyse thématique met en lumière quatre thèmes: (a) la résilience, (b) les besoins relationnels et l’alliance thérapeutique, (c) la quête d’équilibre et (d) la quête de normalité. Sur la base des résultats présentés dans les deux articles, des recommandations sont formulées afin d’améliorer le service à la CDJ et de servir de lignes directrices pour le développement d’initiatives similaires en transition. / Transition from pediatric to adult care is a demanding process for chronically ill young patients, because it takes place during a period of their life when many changes happen simultaneously. Because they are not entirely autonomous yet, youths must learn to take care of themselves while they are being parachuted in a new environment, within a new medical team. The lack of guidance can lead some to take their medicines erratically or to miss appointments. In kidney transplantation, decreased treatment adherence rates can have consequences such as rejection episodes, which sometimes lead to graft loss. To mitigate these problems, two nephrologists from the CHU Sainte-Justine and one nephrologist from the Centre hospitalier de l’Université de Montréal (CHUM) consulted one another to set up a young adult clinic for kidney transplant recipients. This clinic is specifically destined to young adults, those who transitioned as well as those transplanted as adults. This thesis aims to conduct the process evaluation as well as the evaluation of the clinical and psychosocial outcomes of the young adult clinic (YAC), by comparing its group of patients to the young patients who are attending the regular adult clinic (RAC). In the first article, which presents the process evaluation, semi-structured interviews are conducted with 10 YAC patients, to describe their experience of the clinic and identify its key components as well as possible areas of improvement. Thematic analysis highlights six themes that characterize patients’ experience: (a) autonomy support versus overprotection, (b) stability anchors through uncertainty, (c) identification and belongingness, (d) complementarity of approaches between pediatric and adult care settings, (e) an environment matching young adults’ lifestyles and (f) reasons for non-adherence. In the second article, which presents the outcome evaluation, a quantitative and qualitative mixed methodology is used to contrast the experience of 17 YAC patients with the experience of 16 RAC patients, to verify the YAC’s efficiency and to check if self-determination theory (SDT) is relevant in our context. Comparative quantitative analyses reveal that the YAC seems efficient especially during the critical period post-transition or post-transplant in adult setting. Attending the YAC seems to minimize the incidence of medical complications, to improve treatment adherence and patients’ physical quality of life. Correlational analyses establish relationships between SDT variables (perceived autonomy support, autonomous or controlled motivation, perceived competence), treatment adherence and quality of life. Thematic analysis highlights four themes: (a) resilience, (b) relational needs and the therapeutic alliance, (c) quest for balance and (d) quest for normalcy. On the basis of the findings presented in the two articles, recommendations are formulated in order to improve the YAC services and to serve as guidelines for the development of similar transition initiatives.

High school students need to be equipped with the competencies that may enable them to adapt to the increasing demands of learning in the school and beyond. To this end, the main research question of this study was, namely How can the self-regulated learning of adolescents be developed at high school? The aim of the study was to design, implement and evaluate a study skills programme for high school students. The social-cognitive theory, in particular the self-regulated Learning (SRL) theory, was used as the conceptual framework on which this study was based. An explanatory, sequential, mixed-methods research design was implemented. Purposeful sampling was used to select the participants in the three phases of the research project. Two classes of Grade 10-students (an experimental and a comparison group) from one school participated in the study, as follows: (i) in the first quantitative phase both classes wrote a pre-test, using the Learning and Strategies Inventory - High School Version (LASSI-HS); (ii) this was followed by a qualitative phase over 10 weeks. During this time a programme was implemented with the experimental group, once per week for 30 minutes (during school hours), and a 30 minute session in the afternoons. Individual work was also done with eight students, who were purposefully sampled. Between one and four sessions were held with each of the eight students. During the 10 weeks data were collected continuously by means of individual interviews with the eight students, as well as from their journals. In addition, the researcher collected data by means of field-notes. (iii) After the 10 weeks, the final quantitative phase involved both the experimental and the comparison groups in the writing of a post-test. The results indicated that the programme to enhance the students’ goal-setting, self-monitoring and self-evaluation strategies was successful. The students also indicated an improvement in their attitudes, motivation, information-processing, and in selecting the main ideas in their study material. However, shortcomings were noted in certain areas. Based on the literature and the empirical findings of the study, an improved programme for the development of the adolescents’ SRL in high school was designed. The programme recommended the early commencement of the programme, and that the two problem areas that were identified, namely time-management and motivational strategies be emphasised. / Psychology of Education / D.

Le but de cette recherche est d’évaluer l’importance du paysage culturel dans la résilience des communautés urbaines post-catastrophes. Ce travail se concentre sur le quartier du Lower Ninth Ward dans la ville de La Nouvelle-Orléans (États-Unis) après le passage de l’ouragan Katrina en 2005. Les catastrophes naturelles prennent une envergure et causent des dommages considérables lorsqu’elles touchent des villes. La reconstruction post -désastre est donc très dispendieuse pour les villes et les gouvernements, d’autant que certaines régions sont dévastées au point qu’elles doivent être reconstruites au complet. Cependant, le coût le plus lourd à assumer reste celui en vies humaines et si rebâtir les éléments concrets d’une ville est une tâche difficile à entreprendre, reconstruire une communauté est considérablement plus complexe. Dans le but de comprendre une telle démarche, cette recherche se concentre sur les éléments intangibles, comme l’attachement au lieu et les réseaux sociaux, dont une communauté a besoin pour se reconstituer de façon durable et résiliente. Le concept de résilience est très contesté dans la littérature et plusieurs chercheurs se sont essayés à le mesurer. Cette recherche adopte une perspective critique sur le concept et le revisite d’un point de vue holistique pour mettre en lumière sa complexité. Cette démarche permet de remettre en question l’importance de mesurer un concept finalement en perpétuelle redéfinition dans le temps et selon les échelles géographiques. De plus, en établissant une relation entre résilience et paysage culturel, il a été possible de mieux comprendre la complexité de la résilience. Touchant à plusieurs disciplines (architecture de paysage, urbanisme et sociologie), cette recherche utilise une méthodologie qui reflète son aspect multidisciplinaire : les méthodes mixtes. Ces dernières permettent la collecte de données quantitatives et qualitatives qui produisent une vue globale de la situation post-Katrina à travers le regroupement de recensions statistiques, d’observations de terrain et d’articles de journaux. Parallèlement, des entretiens ont été réalisés avec des résidents du quartier ainsi qu’avec des professionnels pour mieux comprendre les différents points de vue. Cette méthodologie a permis de produire des résultats au niveau du cas d’étude autant qu’au niveau théorique. La recherche valide l’importance de prendre en compte le paysage culturel dans les situations post-catastrophes, (en particulier) dans la mesure où il s’agit d’un élément souvent négligé par les urbanistes et les acteurs locaux. En effet, les éléments constitutifs du paysage culturel tels que l’attachement au lieu et les réseaux sociaux, participent d’un sentiment d'appartenance (« home ») et d’une volonté, pour les résidents, de reconstruire leurs habitations, leur communauté ainsi que leur quartier. Toutefois, il faut reconnaître que ces éléments ne suffisent pas à retrouver ce qu’ils ont perdu. Ainsi, l’étude du paysage culturel permet non seulement de mieux comprendre la complexité de la résilience, mais démontre également que cette dernière est une construction sociale. / The purpose of this research is to determine the importance of using the cultural landscape in evaluating the resilience of an urban community after the occurrence of a natural disaster. The focus is on the neighborhood of the Lower Ninth Ward after Hurricane Katrina in 2005 in the city of New Orleans. Natural disasters are gaining significance and magnitude when they hit cities, which are becoming more and more populated over the years. The damage these disasters cause is colossal. It is very costly for cities to undergo major disasters and sometimes, large sections of cities need to be entirely rebuilt. The costliest price is the human life, and as history marks it, too many lives have perished due to disasters. While rebuilding is a challenging task, yet feasible, rebuilding a community is not as tangible as rebuilding the infrastructure. This research focuses on the many intangible aspects, like place attachment and social networks, a community needs to rebuild itself in a sound and resilient way. The concept of resilience is very contested in the literature and many have attempted to measure it. This research takes a step back and scrutinizes the concept of resilience from a holistic perspective, which highlights its complexity. This leads to questioning the importance of measuring the concept, especially that it changes with time and with the different scales of geography. In addition, a relationship between the cultural landscape and resilience is established, which allows for a better understanding of this complexity. Taking a little from multiple disciplines (Landscape Architecture, Urban Planning, and Sociology), this research resorts to a methodology that reflects its multidisciplinary aspect. The methodology is the mixed methods research design, which allows the collection of quantitative and qualitative data. The focus is to gather census data, newspaper articles, and observations to give a general perspective on the post-Katrina situation. Interviews are collected from residents and from professionals so as to tackle the research from different angles. This allows reaching results at the case study level as well as the theoretical level. This research validates the importance of using the cultural landscape in post-disaster situations as planners and government officials overlook it. Some of the elements that constitute it like place attachment and social networks motivate people to return to their original neighbourhoods and rebuild their homes and community. These elements, however, cannot by themselves give people back what they lost in the disaster. By relating the cultural landscape to the concept of resilience, it implies that resilience is a social construction.
