Multilingualism in classrooms is currently prompting debate and has significantly impacted on schooling in South Africa over the last decade. At present South African educators face the challenge of coping with and finding solutions to culturally and linguistically diverse urban school contexts that did not exist before. In many South African communities young learners, without any prior knowledge of English, are placed in English preschools. Preschool teachers have the demanding task of preparing these multilingual preschoolers for formal schooling in English, and, in addition, are pressurised by parents or caregivers who expect their children to be fluent in English by the time they enter primary school. A group of preschool teachers in a specific urban, multilingual preschool context expressed concern about multilingual preschool learners’ academic performances and their future, and requested advice and support. Consequently a need was identified for speech-language therapists to make their expertise available to multilingual preschool learners, as well as to their preschool teachers. To address this need, an exploratory, descriptive, contextual research design, incorporating the quantitative perspective, was selected to describe the specific educational context of multilingual preschools in the Pretoria Central Business District (CBD) and Sunnyside area. A descriptive survey was conducted and two survey techniques were employed to collect the data, namely a questionnaire and a test battery. The questionnaire was used to collect information from 32 teacher participants to investigate the needs and strengths of preschool teachers and multilingual preschool learners. The test battery was utilised to collect data on the language and communication proficiency in English of 30 learner participants. Results indicated that the teacher participants perceived certain personal challenges while supporting the preschool learners acquiring English as Language of Learning and Teaching (ELoLT). These teachers expressed a need for knowledge and support. They also reported that the multilingual preschool learners in the research context had to communicate in ELoLT despite it being an unfamiliar language. Some of the multilingual preschool learners displayed behaviours that could be indicative of negative influences on their self-esteem. The language and communication assessment revealed that many learner participants’ comprehension and expression in ELoLT were insufficient for learning and that they required support for academic success. In addition, the results support the claim that an integrated view of the multilingual learners’ communication abilities need to be established across contexts, by combining assessment strategies, such as naturalistic and structured assessment, as well as interdisciplinary perspectives. The results of the empirical research was used to propose a service delivery model for the acquisition of ELoLT in the research context. This proposed model may be an effective approach to provide supportive intervention to multilingual preschool learners with linguistic barriers to learning. In addition, initial stage intervention guidelines for the basic level ELoLT learner were offered in response to the needs of the specific community. These guidelines may provide a basis for the planning of intervention strategies to preschool teachers who were concerned about the education and future of multilingual preschool learners. / Thesis (DPhil (Communication Pathology))--University of Pretoria, 2007. / Speech-Language Pathology and Audiology / Unrestricted

South African welfare policies and social problems dictate social service rendering in South Africa. Social workers are involved in various service delivery interventions of which community development (macro focus) and statutory services (micro focus) are two separate specialised interventions. In social work practice there is a need for both interventions, however, there is no clear guidelines for social workers how to integrate these interventions in practice. The aim of this study was to determine how community development and statutory services as two distinctive social work interventions could be integrated in order to render effective, integrated social services within a developmental approach. A qualitative research approach was utilised for the study and data was gathered by means of four focus group interviews. Respondents for the study included social workers and clients who were involved in both statutory and community development interventions. Research findings indicated that statutory and community development interventions are guided by different processes, time frames, and models of implementation, such as the legislative framework in the case of statutory work as opposed to participatory models in community development. The study concluded that there is not only confusion with regard to the role of social workers, but also a high risk of clients loosing trust in the helping relationship when one social worker simultaneously does community work and render statutory services in the same community. The distinctive nature of statutory services and community development calls for other options for the integration of these two intervention levels. This study proposed three options for social workers and NGOs to integrate statutory services and community development. Based on the research findings and conclusions of the study, the researcher proposed guidelines for (1) the development of an integrated model and (2) a policy framework for the integration of statutory services and community development within a developmental approach and finally recommended that such a designed model and policy framework be implemented and the impact thereof on social service delivery be researched. / Dissertation (MSD (Social Development and Policy))--University of Pretoria, 2006. / Social Work / unrestricted

Newborn hearing screening has become an increasingly important element of neonatal care in developed countries whilst only a few fragmented screening programmes are evident in developing countries. The numerous socio-economic, cultural and healthcare barriers in developing contexts do not, however, negate or diminish the need to ensure optimal outcomes for infants with hearing loss through early identification and intervention programmes. South Africa has taken a first step toward addressing this need by publishing a Year 2002 Hearing Screening Position Statement that was produced by the Professional Board for Speech, Language and Hearing Professions of the Health Professions Council of South Africa. Interim recommendations are made toward universal newborn hearing screening programmes in three contexts: well-baby nurseries,; neonatal intensive care units (NICU) and Maternal and Child Health (MCH) clinics through their 6-week immunisation programmes. Although these clinics constitute an unfamiliar hearing screening context, they are essential platforms toward widespread screening of the majority of infants in South Africa. An urgent need therefore exists to ascertain the feasibility of hearing screening programmes at MCH 6-week immunisation clinics in order to guide the future implementation of widespread hearing screening services in South Africa. To attend to this need, an exploratory descriptive design that jointly implements quantitative and qualitative methods in a dominant-less-dominant model of triangulation was utilised to critically describe a screening programme conducted at two MCH clinics in Hammanskraal (a developing, peri-urban South African community). The quantitative methods included a structured interview to compile biographical and risk information; high frequency immittance measurements; hearing screening with OAE and AABR according to specified protocols, and diagnostic assessment of referred infants. The qualitative methods included field notes and critical reflections describing clinics as screening contexts and elucidating interactional processes involved in sustaining programmes. A total number of 510 infant-caregiver pairs were enrolled as subjects during the five-month research period. Results indicate that clinics not only provide a suitable context, but also the possibility of effective collaborations toward facilitating effective initial infant hearing screening programmes. The caregivers and infants who attended the clinics demonstrated significant degrees of socio-economic deprivation. They also reported an increased incidence of risk indicators exacerbating the population’s risk for congenital hearing loss, poor participation in the hearing screening/follow-up process, and subsequent poor involvement in a family-centred early intervention process for infants identified with hearing loss. The screening protocol effectively classified infants into risk categories for hearing loss and established useful norms for high frequency immittance in infants. The efficiency of the programme was acceptable considering the short period of implementation, but inefficient coverage with the AABR and poor follow-up return rates were obtained at the clinics. Despite prevailing barriers, the MCH 6-week immunisation clinics showed promise as platforms for widespread hearing screening programmes for infants in South Africa. The clinical implications and recommendations that emerged from the research conducted in this study were compiled and presented in the form of a preliminary service delivery model for infant hearing screening at MCH clinics. / Thesis (DPhil (Communication Pathology))--University of Pretoria, 2004. / Speech-Language Pathology and Audiology / unrestricted

Cette thèse a pour but de documenter la réorganisation des services effectuée au programme Enfants et adolescents (PEA) du Centre de réadaptation Estrie, Sherbrooke. Une démarche de recherche-action participative (RAP) est utilisée afin de collaborer au développement, à l’implantation et à l’évaluation d’un nouveau modèle de services visant à accroître l’accessibilité et la qualité des services de réadaptation offerts aux enfants ayant une déficience physique. Spécifiquement, les objectifs sont : 1) de documenter les retombées de la réorganisation des services; 2) de réaliser une analyse critique du processus de changement. Des méthodes quantitatives et qualitatives sont utilisées afin d’atteindre ces objectifs. Tout d’abord, la Mesure des processus de soins (MPOC) documente la perception de la qualité avant (2007), pendant (2008) et après (2009) l’implantation du nouveau modèle de services. Au total, cet outil est employé auprès de 222 familles et 129 intervenants. À quatre reprises, les intervenants et les gestionnaires répondent également à un questionnaire sur leurs perceptions des forces, des faiblesses, des opportunités et des menaces au PEA. En 2008 et en 2009, des focus groups et des entrevues téléphoniques sont réalisées auprès des familles (n=5), des intervenants (n=19) et des gestionnaires (n=13) afin de documenter leurs perceptions sur le processus de changement et sur les retombées de la réorganisation des services. Quant à l’observation participante, elle permet de recueillir de l’information sur le processus de réorganisation des services tout au long de ces trois années. Enfin, les informations recueillies sont analysées à l’aide de différentes approches, dont des tests statistiques et des analyses de contenu utilisant une grille de codification inspirée de la théorie des systèmes d’actions organisées. Les résultats indiquent que davantage d’enfants reçoivent des services en 2009 en comparaison à 2007. De plus, la qualité des services s’est maintenue selon les perceptions évaluées par la MPOC (article 1). L’utilisation d’interventions de groupe contribue fort probablement à augmenter le nombre d’enfants qui reçoivent des services, mais plusieurs défis doivent être adressés afin que cette modalité d’intervention soit réellement efficiente (article 2). Les résultats font ressortir que le processus de réorganisation des services est complexe. L’évaluation des forces, des faiblesses, des opportunités et des menaces d’un programme, de même que l’implication des acteurs dans le processus de développement d’un nouveau modèle de services, favorisent l’amélioration continue de la qualité (article 3). Or, les facilitateurs et les obstacles à l’implantation du nouveau modèle de services évoluent durant la réorganisation des services. Considérant cela, il est important de poser les actions nécessaires afin de soutenir le changement tout au long du processus (article 4). En résumé, cette thèse contribue à l’avancement des connaissances en réadaptation en comblant une lacune dans les écrits scientifiques. En effet, peu de projets visant le développement et l’implantation de nouveaux modèles de services sont évalués et documentés. Pourtant, des modèles tels que celui développé par le PEA semblent prometteurs afin d’améliorer l’accessibilité, et éventuellement, la qualité des services de réadaptation chez l’enfant. / This thesis aims at documenting the reorganization of services that took place within the programme Enfants et adolescents (PEA) of the Centre de réadaptation Estrie, Sherbrooke. Participatory action research (PAR) is used to collaborate in the development, implementation and evaluation of a new model of service delivery aimed at increasing the accessibility and quality of rehabilitation services offered to children with physical disabilities. Specifically, the objectives are to : 1) evaluate outcomes of the service reorganization, and 2) critically analyze the change process. Quantitative and qualitative methodologies are used. First, the Measures of processes of care (MPOC) are utilized to document quality-related perceptions before (2007), during (2008) and after (2009) the implementation of the new service delivery model. In total, these tools are utilized with 222 families and 129 clinicians. On four occasions, clinicians and administrators also responded to a questionnaire on the program’s strengths, weaknesses, opportunities and threats. In 2008 and 2009, focus groups and phone interviews are conducted with families (n=5), clinicians (n=19) and administrators (n=13) to document their perceptions of the change process and the service reorganization outcomes. Participatory observation allowed collecting data during the whole process of service reorganization. Finally, all the data collected are analyzed using different approaches, such as statistical tests and content analysis using an emerging coding grid inspired from the organized action systems theory. Results indicated that the program served more children in 2009 compared to 2007. Moreover, service quality was maintained according to perceptions evaluated with the MPOC (article 1). The utilization of intervention groups probably contributed to the increased number of children receiving services, but many challenges have to be overcome to ensure effective use of this service delivery method (article 2). Results highlight that reorganizing services is a complex process. Evaluating strengths, weaknesses, opportunities and threats of a new program, as well as the involvement of stakeholders to develop a new model of service delivery, contribute to quality improvement efforts (article 3). However, the facilitators and barriers to the implementation of a new model of service delivery evolved during the reorganization process, and it is essential to take the required actions to sustain changes through the transformation process (article 4). In summary, this thesis contributes to increasing the knowledge in rehabilitation by providing information in an area of the literature where little has been published. Indeed, few projects aiming at developing and implementing new models of service delivery are evaluated and documented. Models, such as the one developed by the PEA, seem interesting to increase accessibility, and eventually, the quality of rehabilitation services for children.

La conception d’un produit ou d’un service en Santé est un processus complexe et risqué. Il doit intégrer dans les phases précoces de conception les normes, les contraintes réglementaires, les données de surveillance et d’évaluation de la sécurité jusqu’à l’autorisation de mise sur le marché pour les dispositifs médicaux, mais également les préférences des utilisateurs experts : professionnels de santé ou non-experts : patients. Dans le marché compétitif des nouveaux produits ou services en Santé, l’enjeu pour les ingénieurs est de faire coïncider les besoins des utilisateurs à leur contexte et usages tout en intégrant toutes les parties prenantes du système de soin. Innovation médicale, technologique et organisationnelle, la télémédecine (TM) est l’utilisation des nouvelles technologies pour délivrer des actes médicaux. L’objectif de cette thèse est la mise au point d’une méthodologie centrée sur les utilisateurs et leurs usages pour concevoir, développer, intégrer et valider une application dermatologique de la TM : la télédermatologie. L’opportunité de validation de cette méthodologie pour intégrer et déployer un service innovant dans un service de dermatologie y est également discutée. / Designing product or services for healthcare system is highly complex, costly and risky. It combines constraints such as being a multi decisional and multilevel system with specific financial model linked to the state the healthcare system organization belongs to. In the highly marketing-time sensitive context of innovative products or services, there is challenge for designers to be able to match the new design to the users’ needs, answering to their context or usages while integrating all system stakeholder components. Telemedicine (TM) is the use of ITtechnologies to provide medical care or medical advice. It is considered a care delivery transformation combining medical, technological and organizational innovation. Using the example of Teledermatology a dermatological application of TM, this PhD develops a methodology based upon users contexts and usages to design integrate and provide an assessment model to decision makers. The opportunity to implement and integrate the service in French department of dermatology is discussed.

<p dir="ltr">Ultra-scaled, always-on, smart, wearable and implantable (WI) therapeutic platforms define the research frontier of modern personalized medicine. The WI platform integrates real-time sensing with on-demand therapy and is ideally suited for real-time management of chronic diseases like diabetes. Traditional blood tracking methods, such as glucometers, are insufficient due to their once-in-a-while measurements and the imprecision of insulin injections, which can lead to severe complications. To address these challenges, researchers have been developing smart and minimally invasive microneedle (MN) components for pain-free glucose detection and drug delivery, potentially functioning as an "artificial pancreas". Inspired by natural body homeostasis, these platforms must be accurate and responsive for immediate corrective interventions. However, artificial MN patches often have slow readings due to factors like MN morphology and composition that remain poorly understood, hindering their optimization and integration into real-time monitoring devices. Despite extensive, iterative experimental efforts worldwide, a holistic framework incorporating the interaction between MN sensing and therapy with fluctuating natural body functions is missing. In this thesis, we propose a generalized framework for glycemic management based on the interaction between biological processes and MN-based operations. The results, incorporating theoretical insights from the 1960s and recent advancements in MN technology, are platform-agnostic. This generality offers a unique template to interpret experimental observations, justify the recent introduction of drugs like GLP-1 cocktails, and optimize platforms for accurate and fast disease management. </p>
