Education is essential in providing future human capital that is much needed to build a sustainable, competitive economy. However, the importance of a quality education is often underestimated. In order to enhance working conditions of educators, it seems essential to investigate the role of the positive psychology paradigm by means of developing teachers’ areas of deficiencies and capitalising on their strengths in order for them to reach their full potential and flourish. The current study aimed to adapt and validate the recently developed Strengths Use and Deficit Improvement Questionnaire (SUDIQ) in an attempt to make it suitable for educators. The general objective of this research study was to establish the psychometric properties of the SUDIQ by means of confirmatory factor analysis (CFA), convergent, discriminant and empirical validity. A cross-sectional field survey design and a convenience sample of educators from several educational institutions in the Gauteng Province (N = 502) was utilised to gather the data. CFA was used to test the factorial validity of the adapted SUDIQ scale. In order to prove convergent and discriminant validity, the relationships between the SUDIQ dimensions and similar theoretical constructs (job resources, strengths use, psychological capital, proactive behaviour and person-job fit) as well as constructs postulated to be unrelated to the SUDIQ dimensions (age and education) were determined. Finally, the relationship between the SUDIQ dimensions with vigour, dedication, emotional exhaustion and depersonalisation was determined by using multiple regression analysis. The results confirmed that the SUDIQ comprised a four-factor structure. These four factors were perceived organisational support for strengths use, perceived organisational support for deficit improvement, proactive behaviour towards strengths use and proactive behaviour towards deficits improvement. These dimensions were positively related to the scales such as the strengths use scale, autonomy, supervisor and colleague support, psychological capital, proactive behaviour, and person-job fit. Anticipated perceived organisational support for deficit improvement and proactive behaviour towards strengths use and proactive behaviour towards deficit improvement were unrelated to age. The scales were also relatively weakly related to education. Furthermore, the results revealed that perceived organisational support for strengths use, proactive behaviour towards strengths use and proactive behaviour towards deficit improvement were significant predictors of both vigour and dedication. However, it was found that the only SUDIQ dimension that predicted emotional exhaustion and depersonalisation was proactive behaviour toward strengths use. Recommendations were made to be applied in practice, as well as for future research. / MCom (Industrial Psychology), North-West University, Potchefstroom Campus, 2014

Bibliography: leaves 207-224 / Abstracts and keywords following the Appendices / This thesis evaluates Ethiopian higher learning institutes’ digital libraries (DLs) for their usability and usefulness. The outcome contributes knowledge by helping to propel development efforts; satisfy DL stakeholders; provide information and fill information gaps; serve as cross-reference for academicians and researchers in the discipline; make decisions and solve managerial issues in DLs of the developing world; and provide scientific interests and merits for the advancement of information systems. When undertaking usability and usefulness evaluation research in DLs, there is no agreed-upon established conceptual framework that guides researchers in the developing world. Therefore, the overall objective of this research is to propose a framework for DL evaluation that fits into the context of developing countries. As the study is concerned with users’ internal attributes, the interpretive research paradigm is applied. A qualitative research approach is employed and a case study research design is followed. Multiple data-collection techniques, namely semi-structured interviews (17 respondents), open-ended questionnaires (17 respondents) and observations (4 observations) are employed. The study encompasses four public university DLs in Ethiopia. The participants have a positive perception of all attributes of usability. Most of the attributes of usefulness are also perceived positively, except coverage. The major challenges encountered by participants are network accessibility, interruption and speed, and access restrictions imposed on some DL content. DL benefits include easy access to the DL content, enhanced teaching and research, lower cost and easy sharing of contents. The expectations of users are ensuring resource availability and sustainability, overcoming the absence of user feedback and federated search problems, and improving network infrastructure and speed. The interaction triptych framework (ITF), which is used in the current study, is a well-known framework that is commonly implemented by researchers. However, since it does not incorporate the contextual situation of developing countries, ITF has some limitations. Therefore, based on the output of this empirical research and considering the usability and usefulness themes of ITF and its relationships with other socio-technical and contextual themes, a contextual DL evaluation framework is proposed. The proposed framework emphasises the social, institutional and contextual aspects of DLs. The proposed framework has six DL components, namely: DL user; content and collection; system and technology; services and support; user interface; and context. The proposed framework is called a digital library components interaction evaluation framework. / Lo mqondo uhlaziya imitapo yolwazi yedijithali (i-DLs) yezikhungo zokufunda ephezulu zase-Ethiopia ngokusebenziseka kwazo nokuba wusizo. Umphumela unikela ngolwazi ngokusiza ukuhambisa imizamo yentuthuko; ukwanelisa ababambiqhaza be-DL; ukuhlinzeka ngolwazi nokugcwalisa izikhala zolwazi; ukusebenza okubhekiswe kukho kwezifundiswa nabaphenyi emkhakheni; yenza izinqumo futhi ixazulule izingqinamba zokuphatha kuma-DL wezwe elisathuthuka; futhi unikeze izintshisekelo zesayensi kanye nokufaneleka ekuthuthukisweni kwezinhlelo zolwazi. Lapho wenza ucwaningo lokusebenziseka neliwusizo okuhlaziya kuma-DL, akukho luhlaka lomqondo okuvunyelwene ngalo oluhola abacwaningi ezweni elisathuthuka. Ngakho-ke, inhloso ephelele yalolu cwaningo ukuphakamisa uhlaka lokuhlaziya kwe-DL oluhambisana nomongo wamazwe asathuthuka. Njengoba ucwaningo luphathelene nezimpawu zangaphakathi zabasebenzisi, inqubo yocwaningo ehumushekayo iyasetshenziswa. Indlela yokucwaninga esezingeni elifanele iyasetshenziswa bese kulandelwa ukwakheka kocwaningo lwesifundo. Kusetshenziswa amasu amaningi wokuqoqa imininingwane, njengezingxoxo ezihlelwe kahle (abaphenduli abayi-17), imibuzo evulekile (abaphenduli abayi-17) kanye nokubhekwayo (okubhekwayo oku-4). Lolu cwaningo luhlanganisa ama-DL amane wemfundo ephakeme yomphakathi wase-Ethiopia. Abahlanganyeli banombono omuhle wazo zonke izici zokusebenziseka. Iningi lezimpawu eziwusizo zibonwa kahle futhi, ngaphandle kokumbozwa. Izinselela ezinkulu ababambiqhaza abahlangabezana ngazo ukufinyeleleka kwenethiwekhi, ukuphazamiseka nejubane, nemikhawulo yokufinyelela ebekiwe kokunye okuqukethwe kwe-DL. Izinzuzo ze-DL zifaka ukufinyelela okulula kokuqukethwe kwe-DL, ukufundiswa okuthuthukisiwe nocwaningo, izindleko eziphansi nokwabelana okulula kokuqukethwe. Okulindelwe abasebenzisi ukuqinisekisa ukutholakala kwezinsiza nokusimama, ukunqoba ukungabi bikho kwempendulo yomsebenzisi nezinkinga zokusesha ezihlanganisiwe, nokwenza ngcono ingqalasizinda yenethiwekhi nejubane. Uhlaka lokusebenzisana lwe-triptych (ITF), olusetshenziswa ocwaningweni lwamanje, uhlaka olwaziwa kakhulu olusetshenziswa ngokuvamile ngabaphenyi. Kodwa-ke, njengoba lungafaki isimo somongo samazwe asathuthuka, i-ITF inemikhawulo ethile. Ngakho-ke, ngokuya ngokukhishwa kwalolu cwaningo olunamandla kanye nokubheka ukusebenziseka nosizo lwezindikimba ze-ITF kanye nobudlelwano bayo nezinye izingqikithi zomphakathi nezobuchwepheshe nezingqikithi zomongo, kuhlongozwa uhlaka lokuhlaziya lomongo lwe-DL. Uhlaka oluhlongozwayo lugcizelela izici zenhlalo, zesikhungo nezingqikithi zomongo zama-DL. Uhlaka oluhlongozwayo lunezingxenye eziyisithupha ze-DL, okuyilezi: Umsebenzisi we-DL; okuqukethwe neqoqo; uhlelo nobuchwepheshe; izinsizakalo nokwesekwa; isikhombimsebenzisi somsebenzisi nomongo. Uhlaka oluhlongozwayo lubizwa ngohlaka lokuhlaziya kokusebenzisana kokuqukethwe komtapo wolwazi wedijithali. / Hierdie proefskrif evalueer Ethiopië se hoër leerinstellings se digitale biblioteke (DBe) ten opsigte van hulle bruikbaarheid en nuttigheid. Die uitkoms dra by tot kennis wat kan help om die ontwikkelingspogings aan te dryf; om belanghebbers van digitale biblioteke tevrede te hou; om inligting te verskaf en inligtingsgapings te vul; deur te dien as kruisverwysing vir akademici en navorsers in die vakgebied; om besluite te neem en bestuursaangeleenthede in digitale biblioteke van die ontwikkelende wêreld op te los; en om wetenskaplike belange en meriete vir die bevordering van inligtingstelsels te voorsien. Wanneer bruikbaarheids- en nuttigheidsevalueringsnavorsing in digitale biblioteke onderneem word, is daar geen ooreengekome, gevestigde raamwerk wat leiding aan navorsers in die ontwikkelende wêreld kan gee nie. Die algehele doelwit van hierdie navorsing was derhalwe om ’n raamwerk vir die evaluaering van digitale biblioteke voor te stel wat in die konteks van ontwikkelende lande pas. Omdat die studie gemoeid is met gebruikers se interne eienskappe, is die vertolkende paradigma gebruik. ’n Kwalitatiewe navorsingsbenadering is gebruik en ’n gevallestudie-navorsingsontwerp is gevolg. Veelvuldige data-insamelingstegnieke, naamlik semigestruktureerde onderhoude (17 respondente), oop vraelyste (17 respondente) en waarnemings (vier waarnemigs), is ingespan. Die studie sluit vier openbare universiteite se digitale biblioteke in Ethiopië in. Die deelnemers het ’n positiewe persepsie van al die eienskappe van bruikbaarheid. Die meeste van die eienskappe van nuttigheid word ook as positief waargeneem, met die uitsluiting van voorsiening. Die grootste uitdagings wat die deelnemers ervaar het, was netwerktoeganklikheid, -onderbrekings en -spoed en die toegangbeperkings wat sommige digitale biblioteke oplê. Voordele van digitale biblioteke sluit die volgende in: toegang tot digitalebiblioteekinhoud; beter onderrig en navorsing; laer koste; en die maklike deel van inhoud met ander. Die verwagtings van gebruikers verseker hulpbronbeskikbaarheid en -volhoubaarheid, en om die afwesigheid van gebruikersterugvoer en gefedereerde soekprobleme en die verbetering van netwerkinfrastruktuur en -spoed te oorkom. Die interaksietriptiekraamwerk (ITF) wat in hierdie studie gebruik is, is ’n bekende raamwerk wat algemeen deur navorsers geïmplementeer word. Omdat dit egter nie die kontekstuele situasie van ontwikkelende lande inkorporeer nie, het ITF sekere beperkings. Gebaseer op die uitset van hierdie empiriese navorsing en met die inagneming van die bruikbaarheids- en nuttigheidstemas van ITF en sy verhouding met ander sosio-tegniese en kontekstuele temas, word ’n kontekstuele digitalebiblioteekraamwerk derhalwe voorgestel. Die voorgestelde raamwerk beklemtoon die sosiale, institusionele en kontekstuele aspekte van digitale biblioteke. Die voorgestelde raamwerk het ses digitalebiblioteekkomponente, naamlik: digitalebiblioteekgebruiker; inhoud en insameling; stelsel en tegnologie; dienste en ondersteuning; gebruikerkoppelvlak; en konteks. Die voorgestelde raamwerk word ’n interaksie-evalueringsraamwerk vir digitalebiblioteekkomponente genoem. / School of Computing / D. Phil. (Information Systems)

During August 2008 commissioners, senior tax administrators and policy makers from 28 African countries attended the International Conference on Taxation, State Building and Capacity Development in Africa. The objective of the conference had been to investigate how African countries can improve their resource mobilization, thereby decreasing Africa’s reliance on foreign aid, improving the fiscal independence of African countries and improving the living conditions of their citizens. It was identified during the conference that African countries can improve their resource mobilization through an improvement of their existing taxation structures. An improvement in existing taxation structures could in turn be achieved through improved sharing of information between African tax authorities on their tax structures currently in place, as well as the habits of their respective taxpayers. In order to facilitate the improved sharing of information, as well as to better equip African Tax Administrations for the task at hand, the African Tax Administration Forum (ATAF) was formed. The aim of this research is to determine whether any progress has been made regarding tax administration reform by African countries following the Conference on Taxation, State Building and Capacity Development in Africa, during the period 2008 to 2012. This has been determined by evaluating the structures of the ATAF and the activities implemented by the ATAF during the period 2008 to 2012 to meet its initial strategic objectives. Secondly, African countries that were previously members of SADC, and have since become members of the ATAF as well, were evaluated in order to determine whether the countries in question have implemented tax administration and governance reforms during the period 2008 to 2012, which have led to an improvement in the tax administration and governance structures of the countries in question. Furthermore, an evaluation was performed as to whether the improvements have led to an improvement in the fiscal independence and humanitarian conditions of the countries in question, during the period 2008 to 2012. The conclusion arrived at reveals that the ATAF has implemented several activities during the period 2008 to 2012, to meet its initial strategic objectives. Furthermore, all the analysed African countries have improved their tax administration structures during the period 2008 to 2012. Unfortunately, not all the countries analysed have been able to improve their governance structures during the period 2008 to 2012 as well. However, where a country has been able to improve both its tax administration and governance structures during the period 2008 to 2012, its fiscal independence and humanitarian conditions have also improved during the period 2008 to 2012. / MCom (South African and International Taxation), North-West University, Potchefstroom Campus, 2014

The tax system in South Africa makes provision for every South African citizen to contribute to a greater or lesser extent to funding the National Health Insurance (NHI), either through VAT or PAYE. However, as a result of the high unemployment rate, a large gap exists between tax and non-tax contributors. The question can now be asked whether it is fair that just a small percentage of taxpayers are responsible for the total funding of the NHI. Furthermore, it could be asked whether the taxpayer is aware of the additional tax burden the NHI will impose on him/her. The purpose of this research was to investigate three countries, namely, Brazil, Spain and Germany, where some form of NHI is in operation, in order to find a possible appropriate funding model for South Africa's NHI and, ultimately, to make conclusions and recommendations based on the outcomes. It was subsequently found that, although the taxpayer should be more heavily taxed in order to fund the NHI, there are a few other possibilities for distributing the tax burden more evenly. However, the impact of the proposed adjustment to increase VAT could have a negative impact on the non-taxpayer and might contribute to greater poverty in South Africa. / MCom (South African and International Taxation), North-West University, Potchefstroom Campus, 2014

In terms of assessment practices, in all facets of education there is a strong focus on assessment at the end of learning. New trends in the literature motivate for the continuous use of assessment strategies in classrooms, with a learner-centred approach. Many questions arise on this topic: When lecturers review their own higher education classroom assessment practices, what will be the extent of their discovery? Are they still inclined to do assessment after teaching and learning has taken place? Or are they moving towards continuous classroom assessment practices in line with the new trends? Is there still a place for classroom assessment at the end of teaching and learning? Should the one or the other be used or should there be a balance between the various strategies? With students perceiving assessment as being judgemental and oppressive and as the most political of all educational processes (Reynolds et al., 2000:268), how does the power struggle unfold in the classroom? By means of participatory action research I encouraged lecturers to reflect critically on their own classroom assessment practices. The lecturers engaged in critical discourses regarding their teaching, learning and assessment strategies and subsequently engaged in transformative actions resulting from their critical reflections. The aim of the research was to determine whether an emancipatory praxis had been developed and whether their reflections had brought about change and improved their classroom assessments. I wished to understand how the changes they had experienced were infused with theories of empowerment, emancipation and liberation. The nature of curriculum praxis of classroom assessment was investigated to determine the status of classroom assessment in a specific higher education context and to see how the balanced assessment system is reflected and how classroom assessment develops as an emancipatory praxis. / MEd (Curriculum Development), North-West University, Potchefstroom Campus, 2014

Summaries in Afrikaans and English / Text in Afrikaans / Two opposing approaches to beginning reading are used, namely the phonological and global approach, under which the whole word, whole sentence and whole language methods are classed. The whole crux of the controversy is situated in beginning reading as an explicit, intensive and systematic method of teaching phonics, as opposed to implicit beginning reading through discrimination of global configurations, augmented by psycholinguistic guesses within reading context. Arguments about the advantages and disadvantages of the opposing methods have been hurdled to and fro for decades without any discernible gain. The question emerged whether research on brain physiology with respect to language and reading, a relatively new field of study, could shed light on the foundation of an accountable method for beginning reading. Renewed insights to the controversial differences were gained, and brain physiologically accountable parameters as a base for a beginning reading method were framed from these insights. / Twee opponerende aanvangsleesbenaderings word in die skole gebruik, naamlik die fonologiese benadering en die geheelbenadering, waaronder die geheelwoord-, geheelsinen die geheeltaalmetode ressorteer. Die kern van die verskil tussen die aanvangsleesbenaderings le in aanvangslees as eksplisiete, intensiewe en sistematiese foneemonderrig, teenoor implisiete aanvangslees wat die waarneming van globale konfigurasies, aangevul deur psigolinguistiese raaiskote binne die leeskonteks, aanmoedig. In die polemiek om die beste leesmetode word argumente oor die voor- en nadele ten opsigte van die begronding van hierdie opponerende metodes reeds dekades heen en weer geslinger. Navorsingsresultate word eindeloos, sonder duidelike winste, met mekaar vergelyk. Dit het die vraag laat onstaan of navorsing ten opsigte van die breinfisiologie met betrekking tot taal en lees, 'n relatief nuwe studieveld, moontlik lig sou kon werp op die begronding van 'n verantwoordbare aanvangsleesmetode. Die literatuurstudie ten opsigte van breinfisiologie het vernuwende insigte oor die polemiese begrondingsverskille na vore gebring, en breinfisiologies-verantwoordbare parameters as basis vir 'n aanvangsleesmetode is uit hierdie insigte opgestel. / Psychology of Education / M.
