Background No data exist about caregivers’ beliefs surrounding a diagnosis of cerebral palsy (CP), its causes and how this influences caregivers’ perceptions of therapy in poorly-resourced South African settings. Neither is there any information about how rehabilitation therapy influences the life of the child or the caregiver. The appropriateness, the outcomes and the effectiveness of therapy for children with CP in a South African setting have not been studied. Numerous tools and scales for measuring outcomes of rehabilitation relating to both the child and the caregiver are available internationally but none have been validated for use in South Africa. Caregiver-related outcomes were the focus of this study and included maternal well-being and mental health, personal quality of life, availability of support and interaction with the child. These are factors known to potentially be influenced through contact with rehabilitation services. Aims The aims of this study were firstly to ascertain whether caregiver-related outcome measures developed in high-income settings were appropriate for a poorly-resourced South African setting; and secondly, to describe parental perceptions and experiences of rehabilitation therapy received in public service hospitals in disadvantaged areas. Methodology The study was undertaken in two phases. Phase One was a quantitative cross-sectional, analytical study and addressed the first aim. Five scales were identified from the literature as being suitable for measuring the caregiver-related outcomes of interest in this study: the Caregiver-Child Scale, the Family Support Scale, the Personal Quality of Life Scale, the Mental Health Subscale of the Medical Outcomes Study (MOS) Short-form 20 Health Survey, and the Measure of Processes of Care (MPOC) Scale. The first four scales measure aspects of maternal well-being and interaction with the child whilst the MPOC assesses caregivers’ reported experiences of family-centred behaviours of rehabilitation service providers. These scales were modified and adapted to make them relevant to a South African setting through a process that included focus groups with caregivers and experienced therapists. After the modified scales had been translated into six local languages and then back-translated into English, the translators, researcher and interviewers met to discuss discrepancies between the two versions (the original modified English version and the back-translation) and to reach consensus on the final translation. The scales were further refined during a pilot study where two trained interviewers administered the modified scales to 24 caregivers of children attending public service hospitals for therapy. Items in the scales which were confusing for caregivers or which they found difficult to understand were clarified. In addition, where necessary, concrete examples were given of the type of behaviour or action being asked about in the scale. Following the pilot study, two trained interviewers administered the modified scales to a convenience sample of caregivers attending rehabilitation therapy in public service hospitals in Gauteng and Limpopo. The reliability and validity of each scale was assessed using multi-trait scaling and factor analysis. Phase Two employed qualitative methodology to address the second aim of the study. A purposive sample of 24 information-rich caregivers attending therapy in public service hospitals in Gauteng and Limpopo participated in one of five focus groups. The discussions were conducted in local languages. Taped recordings were transcribed and translated into English before being analysed using a grounded theory approach. Results Two hundred and sixty three caregivers from 31 hospitals in Gauteng and Limpopo provinces were interviewed during the first phase of the study. The mean age of their children was 3.3 years (± 2.6).Two-thirds of the children (66%) had severe limitations in motor function and few (15%) could communicate verbally. Only one of the five scales, the Mental Health Subscale, proved to be both reliable and valid in South African settings. A second scale - the MPOC - was potentially useful if reduced to an eight item scale (from the original 20 items). The Family Support Scale was reliable but not valid whilst the Caregiver-Child and Personal Quality of Life Scales were neither reliable nor valid. The process of administering the scales combined with the qualitative data helped to explain why the scales did not perform as well as expected in a South African setting. Reasons for these findings included the caregivers’ inexperience in completing these kinds of questionnaires; their difficulty with the concept of grading their responses which meant that Likert-type scales were difficult for them to complete; and thirdly language and cross-cultural applicability. This was because the scales were developed for very different cultural groups. It was not the questions or scale items that were the problem; it was rather finding the language and words that caregivers themselves would use to express the underlying concepts. The study found that caregivers living in disadvantaged South African settings live very differently from their counterparts in well-resourced areas. They lived in poverty; were beset by financial concerns; often abandoned and rejected by their partners; and endured gossip and ignorant attitudes from their neighbours and the community. The burden of daily care-giving was high as most of the children were severely disabled. This was compounded by concern about the child’s health and the future. Despite this, the study found that they were happy, healthy and generally well satisfied with their lives. Support from informal support structures such as relatives and close family members, together with formal support structures, was an important dimension in helping caregivers cope. Qualitative data from the focus groups yielded information regarding caregivers’ beliefs surrounding the perceived cause of the child’s disability. These ranged from traditional and cultural beliefs to medical explanations, and to frank confusion between the two. This was accompanied by misconceptions about therapy and the outcome thereof. Parental perceptions and experiences of rehabilitation were positive although many caregivers initially expected therapy to provide a cure. Respectful and caring attitudes, “hands on” therapy, practical help and assistance with assistive devices and school placements were aspects of service most valued by caregivers. The study helped define the components of an “ideal” therapy service in disadvantaged South African settings. They would include the availability of parent support groups; greater involvement of fathers, close family members and traditional healers in the rehabilitation process as well as the implementation of innovative strategies to ensure clearer communication and understanding between therapists and caregivers operating in a cross-cultural setting. Elements of care not traditionally perceived as part of therapy such as promoting supportive networks and taking on advocacy role for children with disabilities may offer additional advantages. Conclusion The study confirms the view that scales developed in high-income settings are not necessarily immediately applicable to less well-resourced settings and often require extensive modifications to ensure reliability and validity. Whilst the Mental Health Scale is a reliable and valid tool for caregivers attending public service hospitals in South Africa, other scales, such as the MPOC, a popular scale in North American and Europe, require substantial modification for a South African setting. In addition to highlighting the challenges involved in finding suitable outcome measures of therapy intervention for this population, this study has objectively documented the lives and experiences of caregivers of children with CP in South Africa for the first time together with their experiences and perceptions of rehabilitation therapy. Using this information, the components of an “ideal” rehabilitation service in a disadvantaged South African setting have been identified and described. This may facilitate the establishment of a more effective and appropriate therapy service for caregivers and children with CP living in poor areas.

Thesis advisor: Mary E. Walsh / The out-of-school factors that low-income children face can impact their wellbeing and ability to learn (Rothstein, 2010), leading to low academic performance, and, in turn, high levels of stress among their teachers. One of the numerous potential strategies that exist to address this problem is the implementation of systemic student support interventions, which are hypothesized to support teachers in addition to students (Ball & Anderson-Butcher, 2014). Using the City Connects intervention as an example of a comprehensive, systemic student support intervention that has demonstrated positive effects for students, this dissertation study examines the impact of this same intervention on teachers. The study used data obtained from annual surveys administered to all teachers in public schools (across several districts) where the City Connects intervention was implemented. The sample consisted of 656 responses from teachers in Boston Public Schools that were participating in the City Connects intervention during three designated school years (2012-13, 2013-14, and 2015-16). The study implemented a mixed-methods approach that allowed for an in-depth analysis of teachers’ perceptions of support from the City Connects intervention through both quantitative and qualitative data sources. Following exploratory and confirmatory factor analyses of the survey instrument itself, survey data was analyzed using the Validating Quantitative Data Model (Creswell & Plano Clark, 2007), in which quantitative findings were confirmed and expanded upon through analysis of data from a small number of open-ended survey questions. The results of this dissertation study support the continued use of systemic student support interventions in schools, as data confirm that teachers in schools with City Connects report being supported by the intervention. These results hold for veteran teachers who have been teaching for over sixteen years and have participated in the City Connects intervention for over ten years. Ultimately, the findings of this dissertation study suggest that, in addition to leading to positive changes in students’ developmental trajectories, student support interventions can improve the experiences of other members of the school community. / Thesis (PhD) — Boston College, 2018. / Submitted to: Boston College.

Speech technologies such as text-to-speech synthesis (TTS) and automatic speech recognition (ASR) have recently generated much interest in the developed world as a user-interface medium to smartphones [1, 2]. However, it is also recognised that these technologies may potentially have a positive impact on the lives of those in the developing world, especially in Africa, by presenting an important medium for access to information where illiteracy and a lack of infrastructure play a limiting role [3, 4, 5, 6]. While these technologies continually experience important advances that keep extending their applicability to new and under-resourced languages, one particular area in need of further development is speech synthesis of African tone languages [7, 8]. The main objective of this work is acoustic modelling and synthesis of tone for an African tone,language: Yorùbá. We present an empirical investigation to establish the acoustic properties of tone in Yorùbá, and to evaluate resulting models integrated into a Hidden Markov model-based (HMMbased) TTS system. We show that in Yorùbá, which is considered a register tone language, the realisation of tone is not solely determined by pitch levels, but also inter-syllable and intra-syllable pitch dynamics. Furthermore, our experimental results indicate that utterance-wide pitch patterns are not only a result of cumulative local pitch changes (terracing), but do contain a significant gradual declination component. Lastly, models based on inter- and intra-syllable pitch dynamics using underlying linear pitch targets are shown to be relatively efficient and perceptually preferable to the current standard approach in statistical parametric speech synthesis employing HMM pitch models based on context-dependent phones. These findings support the applicability of the proposed models in under-resourced conditions. / PhD (Information Technology), North-West University, Vaal Triangle Campus, 2014

Philosophiae Doctor - PhD / South Africa is committed to accelerating the roll-out of information and communication technologies (ICTs) to support development at all levels. E-inclusion intermediaries (e-IIs) are used in the country to bridge the digital divide and to create equal opportunities for citizens to benefit from using ICTs. E-IIs are established mainly in under-resourced communities by private, public and third-sector organisations to provide physical access to ICT services for free or at a very low cost. The aim of e-IIs is to make ICT services affordable for and accessible to marginalised and poor community members, who can use the ICT to support community development. The debate is ongoing regarding the contribution of e-IIs towards community development due to, in part, the lack of quantifiable evidence to support the impact that the e-IIs have on development in the communities. Furthermore, despite the existence of e-IIs in communities, there still are community members who do not use the e-IIs. This has been attributed to the lack of awareness of the e-IIs and the services they provide. This lack of awareness is often blamed on the ineffective communication strategies of e-IIs. E-IIs are accused of relying heavily on traditional communication channels and conventional mass media, which do not share information and create awareness effectively in the communities. The increased uptake of modern technologies, such as the Internet and mobile devices, in South Africa has created new opportunities to communicate with community members to share information and create awareness. Social media, for instance, which are mostly accessed through mobile devices, have made communication more accessible and inexpensive for community members with limited skills and resources. Social media have also become popular among development actors in their attempt to direct policy, create awareness and garner community members’ support for development interventions. Arguably, e-IIs could also benefit from using social media, which have become popular in some communities, to communicate with community members in order to create awareness of the e-IIs, the services they provide and the benefits of using ICTs to support community development. The investigation undertaken in this study was twofold. Firstly, the quick-scan analysis method was used to analyse fifty e-IIs. Using this method it was possible to explore the services that are provided by e-IIs as well as how e-IIs communicate with community members and other development actors. Secondly, using six in-depth case studies this study further investigated how e-IIs’ services support community development and how the e-IIs communicate for development, paying special attention to their use of social media.

Meanwhile the digital content can be used in each e-reader. In addition, the firms can cooperate with telecommunications firms to provide added-value service. 2. The study found that many internet companies differentiate customer service and build trust from customer by online services to create competitive advantage like creating user community to share knowledge and resources; using word of mouth marketing to attract new customers. Executives should focus on their customer-orientated service to meet market demand.

This work increased the value of ferrite process (FP) in three directions: firstly, changed the inferiority of FP on cost by transforming the FP sludge into a catalyst; secondly, used ERFP and elutriation to promote the performance of FP; thirdly, developed Fenton oxidation as a pretreatment step for avoiding the interference from chelating agents. Six ferrite catalysts (MxFe(3-x)O4, M = Cu, Zn, Mn, Ni, Cr or Fe) formed from FP were tested. Experimental results indicate that the Cu-ferrite catalyst with a Cu/Fe ratio of 1/2.5 can completely convert CO to CO2 at an inlet CO concentration of 4000 ppm and a space velocity of 6000 hr-1 were held at 140¢J. The catalytic performance of Cu-ferrite did not reduce even when the concentration of O2 was just 1%. This work proves that the ferrite catalysts have good potential for catalyzing oxidation. For developing FP for effectively treating almost all heavy metal waste liquid, hence an extremely difficult treating target- simulated waste liquid was designed. It contains ten heavy metals - Cd, Pb, Cu, Cr, Zn, Ag, Hg, Ni, Sn and Mn, each at a concentration of 0.002 M. Although conventional FP could not be used to treat the simulated waste liquid completely, the enhanced FP, i.e. ERFP, could be used to satisfy regulatory limits. FeSO4 can be added in the extended stage of ERFP intermittently rather than continuously. The optimum operating parameters in the initial stage are pH = 9 , FeSO4 dosage = 0.2 mol/L, temperature = 90 oC, air supply rate = 3 L/min/L and reaction time = 40 min; in the extended stage, they are intermittent dosing, adding 10 mL 1M-FeSO4 solution per liter waste liquid every 5 min, pH = 9, temperature = 90 oC, air supply rate = 3 L/min/L and reaction time = 80min. Elutriation was conducted to reduce the cost of ERFP and ensure that the sludge met Toxicity Characteristic Leaching Procedure (TCLP) standards. An operating pH from 2.88 to 4 and an elutriation time of 6 h were recommended. Used Fenton oxidation to decompose chelating agent in waste liquid and then treated heavy metal by FP, this research showed that under proper operational conditions Fenton/ ERFP could completely solve the chelating agent interference problem. The best condition for decreasing EDTA using the Fenton method was: pH = 2, ferrous ion initial concentration [Fe2+]0 = 1¡Ñ10-2M, hydrogen peroxide addition rate = 5¡Ñ10-4 mol/min/L and reaction time = 10 min. Lastly, a lot of real waste liquids were treated satisfactorily by applying the results of this study.

Thesis (M.Sc. (Computer Science)) -- University of Limpopo, 2015 / This study investigates the potential of using graphemes, instead of phonemes, as acoustic sub-word units for monolingual and cross-lingual speech recognition for some of the under-resourced languages of the Limpopo Province, namely, IsiNdebele, Sepedi and Tshivenda. The performance of a grapheme-based recognition system is compared to that of phoneme-based recognition system. For each selected under-resourced language, automatic speech recognition (ASR) system based on the use of hidden Markov models (HMMs) was developed using both graphemes and phonemes as acoustic sub-word units. The ASR framework used models emission distributions by 16 Gaussian Mixture Models (GMMs) with 2 mixture increments. A third-order n-gram language model was used in all experiments. Identical speech datasets were used for each experiment per language. The LWAZI speech corpora and the National Centre for Human Language Technologies (NCHLT) speech corpora were used for training and testing the tied-state context-dependent acoustic models. The performance of all systems was evaluated at the word-level recognition using word error rate (WER). The results of our study show that grapheme-based continuous speech recognition, which copes with the problem of low-quality or unavailable pronunciation dictionaries, is comparable to phoneme-based recognition for the selected under-resourced languages in both the monolingual and cross-lingual speech recognition tasks. The study significantly demonstrates that context-dependent grapheme-based sub-word units can be reliable for small and medium-large vocabulary speech recognition tasks for these languages. / Telkom SA

The rapid spread of the coronavirus disease (COVID-19) has impacted the lives of millions around the globe. The COVID-19 pandemic has caused increasing concern among treatment professionals about mental health and risky substance use, especially among those who are struggling with a substance use disorder (SUD). The pandemic's impact on those with an SUD may be heightened in vulnerable communities, such as those living in under-resourced and rural areas. Despite policies loosening restrictions on treatment requirements, unintended mental health consequences may arise among this population. We discuss challenges that under-resourced areas face and propose strategies that may improve outcomes for those seeking treatment for SUDs in these areas.
