Developments since the 20th century indicate that the wellbeing of communities makes for healthy national welfare in strong countries. Community wellbeing is thus a priority for policy makers and service providers. Conceptualization of a meaningful, holistic multidimensional measurement of community wellbeing at micro (community) level has been lacking. Such a concept and its measurement are essential when addressing social exclusion and development issues in the enhancement of community wellbeing is to produce worthwhile results. There is growing recognition that earlier understanding of community wellbeing failed to address development needs and processes at community level. Outsider stakeholder driven top-down one-dimensional community wellbeing (‘silo’) measurements did not address human development needs at community level. Meaningful measurement requires integrated frameworks addressing multidimensional issues conceptualizing wellbeing measurement at community level. Such measurement needs to be combined with the integrated inclusion of social capital influence through ‘insider-outsider’ partnerships. The research study purpose was to develop a community driven holistic, integrative wellbeing assessment model. This model could assist ‘insiders’ (community members) and ‘outsiders’ (policy makers, service providers and community development practitioners) in developing and implementing community driven initiatives towards improved wellbeing. The two main research questions were: 1) which macro level wellbeing assessment factors to consider in an aligned micro level wellbeing assessment? and 2) what is the associative relationship between wellbeing and social capital? Two descriptive sample surveys were conducted utilizing a structured questionnaire. Primary data findings contributed to finalization of a community level wellbeing assessment model. This model would enable estimation of the potential (push and pull) factors that influence the targeted success of suggested community development processes. The assessment model is community driven and owned, with spider and quadrant diagram graph tools indicating first the status of community wellbeing and social capital, then the associative relationships of wellbeing and social capital in ‘insider-outsider’ initiatives for wellbeing enhancement. / Development Studies / D.

For decades there has been growing interest into the crime of child murders. Emphasis was placed on victims and those at risk. Not much focus was placed on perpetrators and their families. Evidence suggests that the family and social systems play a vital role in determining adult violent behaviour. This qualitative study aims to explore the experiences of convicted child murderers in their family and social system. Data was collected and analysed, using genogram interviews and analysis. Themes were highlighted using hermeneutic thematic analysis, within a post-modern paradigm. Results were presented in the form of genogram analysis and thematic content analysis. Prominent themes that arose were separation, rejection, abuse, neglect and substance abuse. These life experiences together with poor education are some of the characteristics that may have contributed to the child murderers actions towards children. / Psychology / M. A.

We propose a method based on the Helfand moment in order to calculate the viscosity properties in systems of particles with periodic boundary conditions. We apply this method to the simplest system in which viscosity already exists: the two-hard-disk model. The escape-rate formalism, establishing a direct relation between chaotic quantities of the microscopic dynamics (e.g. Lyapunov exponents, fractal dimensions, etc.), is applied in this system. The results are in excellent agreement with those obtained by our Helfand-moment method. We extend the calculation of the viscosity properties to systems with more than two hard balls. Finally, we compute viscosity as well as thermal conductivity thanks to our own method also based on the Helfand moment.<p></p> / Doctorat en sciences, Spécialisation physique / info:eu-repo/semantics/nonPublished

The neural net computer simulations which will be presented here are based on the acceptance of a set of assumptions that for the last twenty years have been expressed in the fields of information processing, neurophysiology and cognitive sciences. First of all, neural networks and their dynamical behaviors in terms of attractors is the natural way adopted by the brain to encode information. Any information item to be stored in the neural net should be coded in some way or another in one of the dynamical attractors of the brain and retrieved by stimulating the net so as to trap its dynamics in the desired item's basin of attraction. The second view shared by neural net researchers is to base the learning of the synaptic matrix on a local Hebbian mechanism. The last assumption is the presence of chaos and the benefit gained by its presence. Chaos, although very simply produced, inherently possesses an infinite amount of cyclic regimes that can be exploited for coding information. Moreover, the network randomly wanders around these unstable regimes in a spontaneous way, thus rapidly proposing alternative responses to external stimuli and being able to easily switch from one of these potential attractors to another in response to any coming stimulus.<p><p>In this thesis, it is shown experimentally that the more information is to be stored in robust cyclic attractors, the more chaos appears as a regime in the back, erratically itinerating among brief appearances of these attractors. Chaos does not appear to be the cause but the consequence of the learning. However, it appears as an helpful consequence that widens the net's encoding capacity. To learn the information to be stored, an unsupervised Hebbian learning algorithm is introduced. By leaving the semantics of the attractors to be associated with the feeding data unprescribed, promising results have been obtained in term of storing capacity. / Doctorat en sciences appliquées / info:eu-repo/semantics/nonPublished

The rising rates of high-risk behaviours, such as substance abuse, unsafe sexual practices and violence in South African schools, have accentuated the need for intervention and prevention programmes in the education system. High-risk behaviour is related to changes and uncertainties at community level. The traditional values and behavioural codes are undermined and there is no corrective action from the community to control this behaviour. This study describes the need for support of adolescents, who are in a state of development and change and whose abilities are increasingly being tested by stress factors from a rapidly changing environment. To meet these needs for support, an experimental peer support programme was implemented in schools. Peer support involves the provision of information about healthy lifestyles and high-risk behaviour, such as substance abuse, crime and HIV/AIDS-related aspects. Through peer support, healthy lifestyles can be modelled, and a forum for the discussion of problems established. Peer supporters can assist their peers in dealing with problems and a context can be created in which new and healthier behavioural patters can develop. Peer support is important because educators and teachers are unable to manage the large number of learners who are experiencing problems and schools offer limited professional psychological support to learners. The objectives mainly entailed the prevention of high-risk behaviour related to HIV/AIDS, crime and substance abuse, as well as the enhancement of learners’ psychological well-being and the social climate in schools. The peer support system was implemented in four experimental schools and four similar schools served as a control group. The schools involved were selected by means of a stratified sampling method. A total amount of 2045 respondents between the ages of 12 and 21 years participated in this study. The peer support system was evaluated in terms of a pre and post-measurement in order to determine the impact of the system on the schools and learners in the schools, and to determine whether the set objectives have been achieved. The hypothesis was that the peer support system would have a positive effect in reducing high-risk behaviour and improving the psychological well-being of learners. A questionnaire was used as a pre and post-measurement tool to determine whether there had been significant changes and/or improvements regarding high-risk behaviour, crime, school climate and psychological well-being in the school system. The experimental and control school communities were compared. Significant differences were found between the experimental group and the control group in terms of behavioural problems in the school, school climate, high-risk sexual behaviour and psychological well-being. Learners’ perception of problem behaviour in the school remained unchanged in the experimental group, whilst the control group’s measurements became statistically significantly (p<0,05) more negative over time. A statistically significant difference at the 5% significance level was found between the control group’s pre and post-measurements regarding learners’ experience of the school climate. The control group’s experience had become more negative at post-measurement, whilst the experimental group’s experience had remained unchanged over time. A statistically significant difference was found between the experimental and control groups (p<0,001) in respect of the level of sexual experience. The number of sexually experienced learners in the control group had increased at post-measurement, whilst the level of learners’ sexual experience had remained constant in the experimental group. Furthermore, a significant increase (p<0,001) was found in the level of sexual activity among the control group during the last 30 days, but not in the experimental group. This implicates that the intervention has had a preventative effect that counters the normal tendency of increased sexual activity with age. More than 60% of learners viewed their friends as sexually experienced. The perceived group norm for the experimental group remained the same over 18 months, whereas a significant increase (p<0,001) was found in the control group. No decrease was found in the psychological well-being of learners in the experimental group at post-measurement, whereas that of the control group had decreased significantly (p<0,05). No statistically significant differences were found for substance abuse and personal control of risk among learners. Although many other variables could play a role in these changes, the conclusion can be made that the peer support system probably had a preventative effect in schools. The study further indicates that approximately two thirds of all learners had been aware of the system and about 40% had used it. The peer system was generally evaluated as positive and the biggest problems were related to the implementation and organization of the system, as well as the confidentiality of information. Recommendations have been made regarding the improvement of project implementation. If enhanced co-operation from school staff can be obtained during implementation of the intervention, the peer support system could function better and a bigger impact in schools could be achieved. In conclusion, it is important that intervention programmes be promoted efficiently in schools in order to facilitate optimal functioning. / Dissertation (MA (Research Psychology))--University of Pretoria, 2006. / Psychology / unrestricted

This study investigated the management of information and communication technologies (ICTs) at academic libraries in selected public universities in Ghana. The purpose for this study was to investigate the managerial processes and challenges in terms of conceptualization, policies, planning, implementation and strategies involved in ICTs adoption in order to formulate strategies for their management in Ghanaian academic libraries. Specifically, the objectives of the study were to review and explore the status and level of ICT diffusion in Ghanaian university; audit the procedures, processes and factors that influence ICT adoption and implementation in Ghanaian university libraries; establish the institutional policies, strategies and human resource that is in place and available for the adoption; determine the factors that hinder the adoption and management of ICTs in Ghanaian university libraries; and design a framework for effective and efficient management of ICTs in Ghanaian public university libraries. The study adopted mixed-method research design approach combining both quantitative and qualitative approaches through the pragmatic worldview to achieve the main purpose of the study. Adopting a survey study design, data was collected from five selected Ghanaian public universities by interviewing the five university librarians/directors, using questionnaires on 313 library staff and making observations within the five libraries. The findings of the study established that the managerial tools/instruments required for effective ICTs management in Ghanaian university libraries include the availability of library ICT policies, a library ICT strategic plan, library ICT installation and maintenance manuals, library ICT integration plans, and standard operations manuals. In addition, adequate funds, skilled manpower, adequate and standard ICT infrastructures among others. However, the study also revealed that there are absence of library ICT policies, lack of processes and procedure guidelines, inadequate funds, lack of management support, inadequate ICT skills among libraries and staff ICT training policies in the academic libraries in Ghana. The study recommends the formulation of ICT policies and strategic plans purposely for the comprehensive management of library ICT systems. Furthermore, the university top management should support their libraries by providing the required resources and motivation for the library managers including the development of stakeholder partnership and collaboration. To galvanise these recommendations, the study proposes a framework for the ICTs adoption and management in Ghanaian university libraries. / Information Science / D. Litt. et Phil.

L’éducation par les pairs est de plus en plus utilisée en promotion de la santé. Elle consiste à faire appel à des personnes pour offrir des interventions de prévention et de promotion de la santé (PPS) à leurs pairs. Une formation est généralement offerte aux pairs avant qu’ils débutent leur implication en PPS. Peu d’études ont examiné l’implantation de programmes de promotion de la santé (PPS) offerts par des pairs, ses déterminants et leurs mécanismes d’action. Cette thèse s’inscrit dans le cadre d’une étude quasi-expérimentale visant à évaluer les effets du programme Vivre en Équilibre (VEE), un PPS offert par des pairs ciblant la peur de tomber et ses conséquences sur la participation sociale des aînés. La thèse vise à développer et appliquer un modèle conceptuel des facteurs influençant l’implantation de programmes offerts par des pairs. Les objectifs spécifiques sont: 1) de développer un modèle conceptuel de l’implantation des PPS offerts par des pairs; 2) de documenter l’implantation de VEE; et 3) d’identifier les facteurs associés à son implantation. À la suite d’une recension des écrits, un modèle conceptuel de l’implantation des PPS offerts par des pairs a été élaboré en se basant sur des travaux conceptuels existants et en adoptant une conceptualisation des PPS en tant que systèmes complexes. Ce modèle postule que des facteurs liés aux individus, au programme et au contexte influencent l’implantation et suggère trois mécanismes (interactions, auto-organisation, processus d’adaptation) par lesquels ces facteurs agissent. Une étude de cas multiples a permis d’analyser l’implantation de VEE dans six résidences pour aînés du Québec. La population rejointe, la fidélité d’implantation, les adaptations, la réponse au programme et les facteurs associés à l’implantation du programme ont été documentés à l’aide de grilles d’observation, de journaux de bord, de fiches de présences, de questionnaires téléphoniques et d’entrevues réalisées auprès des pairs, des répondants de résidences et d’un sous-groupe de participants au programme. Une analyse intra- et inter-cas a permis d’identifier les facteurs associés à l’implantation et de les comparer au modèle élaboré. Au total, 71 aînés ont participé au programme. Les participants recrutés correspondaient majoritairement à la population ciblée par le programme. Les pairs ont offert toutes les activités du programme, mais ont rapporté avoir fait certaines adaptations. Le taux de participation (91%) et le niveau de satisfaction des participants, des pairs et des répondants des résidences étaient élevés. L’analyse révèle que des facteurs liés aux individus (ex. : attitudes des participants, expérience des pairs), au programme (ex. : qualité du contenu et du matériel, formation des pairs) et au contexte (ex. : climat d’implantation) ont influencé l’implantation du programme par le biais des mécanismes identifiés dans le modèle conceptuel. La thèse montre que VEE peut être implanté avec succès par des pairs aînés dans des résidences. Les résultats soutiennent aussi le modèle conceptuel élaboré dans le cadre de cette thèse. Ils apportent un éclairage sur les facteurs associés à l’implantation de VEE et guideront les chercheurs et les intervenants intéressés par l’implantation de PPS offerts par des pairs. / Peer education is increasingly being used in health promotion. In this strategy, peer leaders deliver health promotion programs (HPPs) to their peers. Peer leaders usually attend training before delivering HPPs. Few studies have examined the implementation of peer-led HPPs, along with their determinants and mechanisms of action. This thesis was undertaken as part of a quasi-experimental study aiming to evaluate the effectiveness of Vivre en Équilibre (VEE), a peer-led HPP targeting fear of falling and its consequences on older adults’ social participation. The purpose of this thesis is to develop and apply the implementation framework of peer-led HPPs. More specifically, the objectives are to: 1) develop a conceptual framework of peer-led HPPs; 2) document the implementation of VEE; and 3) identify the factors associated with its implementation. Following a literature review, a conceptual framework of peer-led HPPs was developed based on existing conceptual work and on complex systems theory concepts. This framework postulates that factors related to individuals, to the program and to the context influence implementation. It further suggests three mechanisms (interactions, self-organization, adaptation process) through which these factors may act. A multiple case study analyzed the implementation of VEE among six independent-living residences for older adults in Quebec. Program reach, fidelity of implementation, adaptations, responsiveness, and factors associated with implementation of the program were documented. Observation grids, peer leaders’ logbooks, attendance sheets, phone questionnaires and interviews (with peer leaders, activity coordinators of the residences, and a subgroup of program participants) were used to collect the data. Content analysis and case comparisons helped identify factors associated with implementation of VEE and compare them with the conceptual framework developed. Overall, 71 older adults participated in the program. Most participants corresponded to the program’s target population (i.e. older adults with fear of falling). Peers delivered all program content but adapted some elements. The participation rate (91%) and the satisfaction level of participants, peers and activity coordinators were high. The analysis revealed that some factors related to individuals (e.g., participants’ attitudes, peer leaders’ experience), to the program (e.g., materials and content quality, training) and to the organizational context (e.g., implementation climate) facilitated VEE implementation through mechanisms identified in the framework. This thesis shows that VEE can be successfully delivered by peer leaders in independent-living residences. The results also support the conceptual framework and shed light on factors associated with the implementation of VEE. These results can guide researchers and practitioners interested in implementing peer-led HPPs.

Wie wollen wir diese hochgradig komplexe soziale Welt von heute verstehen, in der bald über 7 Mrd. Menschen auf vielerlei verschlungenen Kanälen miteinander kommunizieren und interagieren, ohne über eine brauchbare ‚General Theory‘ des gegenwärtigen globalen sozialen Weltsystems zu verfügen? Wie wollen wir verstehen, wie das soziale Weltsystem mit seiner ökologischen Umwelt interagiert, wenn wir über keine brauchbare universelle Theorie verfügen, die hinlänglich präzise erklären könnte, wie die ‚globalen Zustände‘ zustande kamen und kommen?

This dissertation is a report on a study about autobiography as genre, focusing on the voice of the white, Afrikaans-speaking woman. The point of departure for this study was a survey of the number of autobiographies written in Afrikaans by these women. With the focus on the limited number of such autobiographies three autobiographies were studied, namely, Met die Boere in die veld (Sarah Raal), My beskeie deel (M.E.R.) and 'n Wonderlike geweld (Elsa Joubert). Within the framework of the complexity systems theory the role of the observer (author/reader) was studied to determine the possibility of demonstrating that when reading/writing an autobiography, some epistemological changes may occur, manifesting as conceptual changes in the mind of the observer. It could be demonstrated that because of women's sensitivity to interpersonal relationships they are capable of acting as unique registers of the complexity of individual existence, while remaining aware of the constant influence, effect and needs of the other. / AFRIKAANS & THEORY OF LIT / MA (AFRIKAANS)
