Les propriétés radiatives sont d'une importance cruciale lors de l'étude des plasmas astrophysiques et de fusion, particulièrement dans des conditions hors équilibre thermodynamique local (hors-ETL). C'est pourquoi nous avons développé un modèle collisionnel-radiatif, capable de calculer les propriétés radiatives en toutes conditions de température et de densité. Nous avons intégré à ce modèle de nouveaux facteurs de Gaunt développés par nous-mêmes. Ces facteurs permettent d'obtenir des sections efficaces des processus atomiques plus précis que les formules classiques et semi-empiriques, nécessaires au calcul des populations atomiques. Ils ont été obtenus en utilisant des méthodes sophistiquées, telles que les méthodes distorted-wave et generelized-line-strength, à l'aide du code FAC. Dans le but de valider nos résultats, nous les avons comparés dans un premier temps, aux calculs de Hill et Rose d'un plasma composé d'un mélange de carbone et de 5% de silicium, dans des conditions ETL et hors-ETL. Les résultats sont très satisfaisants, aussi bien à l'ETL qu'hors-ETL. Nous avons aussi comparé nos résultats à la transmission mesurée par Xiong et al. d'un plasma de silicium à Te = 72 eV et Ne = 1.3 x 10²¹ cm⁻³. Là encore, nous obtenons un bon accord. Cependant, on constate la présence de quelques écarts au niveau du décalage spectral de certaines raies, ainsi que l'absence de certaines transitions. Cette absence peut s'expliquer par certaines configurations électroniques manquantes dans le calcul de structure atomique. Nous nous sommes aussi intéressés à l'absorption d'un mélange de carbone et de 5% de germanium avec un nombre restreint de configurations électroniques. Nous avons exploré l'effet d'interaction de configurations ainsi que l'effet d'un champ radiatif. Nous avons également déduit des lois permettant de calculer rapidement les lois de Planck et de Rosseland. Ces lois concernent pour le moment le carbone, le silicium et le germanium, pour Te entre 250 et 350 eV et Ne entre 2 et 8 x 10²³ cm⁻³. / The radiative properties are of utmost importance when studying astrophysical and ICF plasmas, particularly in non local thermodynamic equilibrium conditions. This is the reason why we have developed a collisional-radiative model that enables us to calculate the radiative properties of plasmas under any temperature and density conditions. We developed and implemented new Gaunt factors to the CR model. These factors greatly improve the precision when calculating the cross sections of the microscopic processes. These cross sections are required to calculate the populations of the atomic levels. We obtained these new factors by using the distorted-wave and generalized line strength methods of the Flexible Atomic Code (FAC).In order to validate our new-developed CR model, we compared our results to those of Hill and Rose, of a plasma composed of carbon and 5% silicon, in LTE and NLTE conditions. We obtained satisfactory results in both conditions. We also compared our results to the experimental transmission measured by Xiong et al., of a pure silicon plasma, with Te = 72 eV et Ne = 1.3 x 10²¹ cm⁻³. Again, we obtained results that are in good agreement with the measured spectrum. However, we noticed some discrepancies in the line shift of some lines, and some missing transitions. This can be explained by the absence of certain electronic configurations in the calculation of the atomic structure with the Cowan atomic code.We also explored the absorption of a plasma composed of carbon and 5% germanium with a restricted number of electronic configurations. We investigated the effect of configuration interaction and the effect of the radiative field. We also developed new laws that predict the Planck and Rosseland mean opacities very quickly. For the time being, these laws work for carbon, silicon and germanium, with Te between 250 and 350 eV, and Ne between entre 2 et 8x10²³ cm⁻³.

The primary objective of this study was to examine the broader impact of institutional quality on enhancing foreign direct investment (FDI) and foreign portfolio investment (FPI) inflows in a sample of twelve emerging market economies for the period 2007 to 2017. We specifically sought to answer questions related to the key drivers of FDI and FPI inflows into emerging markets, with a particular emphasis on the role played by institutional quality factors. We further sought to interrogate the long-run and causal relationships between the key variables of FDI, FPI and institutional quality, in respect of the sample of emerging markets. The study employed the Principal Components Analysis (PCA) to construct a composite index for institutional quality composed of the six Worldwide Governance Indicators. Various other econometric models were applied, including the dynamic panel data generalised method of moments (GMM) model, the panel autoregressive distributed lag (ARDL) model for dynamic heterogeneous panels, and the panel vector error correction model (VECM). The results revealed that FDI in the selected emerging markets was, in the main, attracted by economic growth and institutional quality. Institutional quality, economic rowth and capital account openness were positive determinants of FPI inflows; however, stock market development stood out as the foremost determinant factor. In addition to finding long-run, cointegrating relationships between the key variables, it emerged that there was bi-directional causality between FDI and FPI, as well as between FDI and institutional quality in the long run. Despite the latter findings, the results further suggested that the long-run relationship between the two foreign capital inflows, i.e. FDI and FPI, was more of a substitutability or trade-off nature in our sample of emerging markets. In light of these findings, we recommended that it would be in the best interests of these emerging markets if the responsible policymakers continued to liberalise these economies. Further, it was shown that in order to attract inward international capital flows, financial liberalisation should be coupled with the strengthening of the domestic institutional environment.Strengthening institutions could curtail the persistence of institutional weaknesses and insulate emerging market economies from the adverse effects of volatile capital flows, and in the long-run enhance international capital inflows. / Inhloso enkulu yalolu cwaningo kwaye kuwukuhlola umthelela obanzi kwizinga leziko ekuqiniseni uhlelo lokutshalwa ngqo kwezimali ezweni langaphandle (foreign direct investment; FDI) kanye nemali engena mayelana nokuthengwa kwamagugu (shares, stocks and bonds) angenisa imali ezweni elingaphandle (foreign portfolio investment; FPI) kwizimakethe zamazwe eziyishumi nambili esikhathini esiphakathi kuka 2007 ukufika ku 2017.

Text in English / Abstracts in English, isiXhosa and Afrikaaans / This study’s primary objective was to create a framework for developing authenticity, by exploring women’s experiences of authenticity and how these relate to their wellbeing in a male-dominated work environment. Twelve purposively chosen women participated in the study, comprising six police officers and six traffic officers from the Western Cape province in South Africa. Data were gathered through narrative interviews by using open-ended questions, and analysed by applying thematic analysis. The research findings revealed that challenges or stressors in their law enforcement environment serve as potential agents for moving the self away from best-self in the authenticity dynamic, resulting in the need for coping and therefore for developing authenticity. The framework for developing authenticity was constructed as an ongoing and unfolding process comprising the following: experiencing challenges or stressors; turning within; recognising possible ways of being; managing perceptions, thoughts, emotions and behaviour; making conscious choices and taking responsible actions; as well as evaluating responses and consequences against best-self standards. During this process various best-self characteristics and associated skills are developed and employed, but also serve as best-self standards against which to evaluate growth and transformation. Secondary objectives aimed to advance the concept of authenticity in the study of well-being as a discipline of psychology. It also aimed to make a methodological contribution by applying hermeneutic phenomenological and transpersonal approaches in a novel way. / Eyona njongo yesisifundo ibikukuphuhlisa umgaqo nkqubo wokwenene, oqwalasela izinto abantu basetyhini abadlule kuzo kwaye nokuba zingqamane njani nentlalontle yabo kwindawo zokusebenza eziphethwe ngamadoda.

Twaalf doelgerig gekose vrouens het deelgeneem aan die studie, wie bestaan het uit ses polisiebeamptes en ses verkeersbeamptes uit die Wes-Kaapse provinsie in Suid- Afrika. Data was versamel deur middel van narratiewe onderhoude deur oop vrae te gebruik, en ontleed deur tematiese analise toe te pas. Die navorsingsbevindings het aan die lig gebring dat uitdagings of stressors in hul wetstoepassingsomgewing as potensiële agente dien om die self weg te beweeg van die beste-self in die egtheid dinamika, wat die behoefte aan coping tot gevolg het en dus vir die ontwikkeling van egtheid. Die raamwerk vir die ontwikkeling van egtheid is saamgestel as 'n deurlopende en ontvouende proses wat die volgende insluit: ervaring van uitdagings of stressors; keer na binne; erkenning van moontlike maniere om te wees; hantering van persepsies, gedagtes, emosies en gedrag; maak bewustelike keuses en neem verantwoordelike aksies; sowel as die evaluering van reaksies en gevolge teen die beste-self standaarde. Gedurende hierdie proses word verskeie beste-self eienskappe en verwante vaardighede ontwikkel en aangewend, maar dien ook as die beste-self standaarde om groei en transformasie te evalueer. Sekondêre doelwitte het ten doel om die konsep van egtheid in die studie van welstand as dissipline van sielkunde te bevorder.

Corporate governance failures raise questions by stakeholders seeking explanations why audit committees are failing to play their agency role effectively. The objective of this study was to determine the relation between 49 disclosed audit committee effectiveness variables based on King III Code recommended practices and the external audit opinion expressed in South African central government departments. Descriptive statistics highlighted variances in 14 variables across 93 departments. Categorical principal component analysis categorised the 14 variables into four factor variables and hypotheses. Multivariate ordinal logistic regression tested the hypotheses. Results suggest that disclosure of a higher number of variables was generally associated with a clean audit report, while the association between a higher number of disclosures regarding audit committee structure and profile variables and a clean audit report was significant. Improvements to National Treasury’s disclosure templates and review of departmental managers’ disclosures about audit committees in annual reports are recommended. / Gevalle van korporatiewe beheer mislukking laat vrae by belanghebbers ontstaan waarom ouditkomitees versuim om hul oorsigrol doeltreffend te vervul.

The aim of this explorative and descriptive study was to develop an action plan for criminologists to become specialised practitioners within the South African child justice system. An exploratory, sequential, mixed-methods approach was used, where data was collected during the first phase using a self-administered, semi-structured questionnaire, including closed- and open-ended questions. The questionnaire was distributed to members of the Criminological Society of Africa (CRIMSA), as well as criminologists, magistrates, and other experts in the field of child law, known to the researcher. Sixteen questions were posed to collect data, consisting of nine Likert scale questions and seven open-ended questions. A semi-structured interview schedule was employed during the second phase of the study, to conduct 22 face-to-face and telephonic interviews with experts in the field of child law, probation officers, social workers, and criminologists. Descriptive data analysis was utilised during the first, and thematic analysis during the second phase of this study. The findings indicate that the absence of a regulating, professional body, limits career opportunities for criminologists as far as exercising their skills in practice. Furthermore, it was established that the role and function of criminologists, and the academic field of criminology, remain unfamiliar to various practitioners in the human science professions. Subsequently, criminologists are often considered mere crime researchers with limited applied skills for use in the South African criminal justice system. Though it was proven that, at least to some degree the academic training of criminologists is deficient, it was established that criminologists have a unique skill-set that places them in a unique position to execute various functions within the child justice sector as part of a multi-disciplinary team. Findings suggest that the Child Justice Act (75 of 2008) should be amended to facilitate the inclusion of criminologists in the South African child justice sector. / Die doel van hierdie verkennende en beskrywende studie was om ʼn aksieplan vir kriminoloë te ontwikkel om hulle in staat te stel om gespesialiseerde praktisyns in die Suid-Afrikaanse kindergeregtigheidstelsel te word. ʼn Verkennende, opeenvolgende, gemengdemetode-benadering is gebruik waar data gedurende die eerste fase ingesamel is deur middel van ’n selfgeadministreerde vraelys, wat geslote en oop vrae ingesluit het. Die vraelys is versprei onder lede van die Kriminologiese Vereniging van Suider-Afrika (CRIMSA), asook kriminoloë, landdroste en ander kundiges op die gebied van kinderreg wat aan die navorser bekend is. Altesame 16 vrae is gestel om data in te samel, wat uit nege Likert-skaalvrae en sewe oop vrae bestaan het. ’n Halfgestruktureerde onderhoudrooster is gedurende die tweede fase van die studie gebruik om 22 onderhoude van aangesig tot aangesig asook telefoniese onderhoude met kundiges op die gebied van kinderreg, proefbeamptes, maatskaplike werkers en kriminoloë te voer. Beskrywende dataontleding is gedurende die eerste, en tematiese ontleding gedurende die tweede fase van hierdie studie gebruik. Die bevindings dui aan dat die afwesigheid van ’n regulatoriese, professionele liggaam loopbaangeleenthede vir kriminoloë beperk wat die uitoefening van hul vaardighede in die praktyk betref. Daar is voorts vasgestel dat die rol en funksie van kriminoloë, en die akademiese gebied van kriminologie, onbekend aan verskeie praktisyns in die geesteswetenskapberoepe is. Kriminoloë word gevolglik dikwels bloot as navorsers met beperkte toegepaste vaardighede vir gebruik in die Suid-Afrikaanse strafregspleging beskou. Hoewel bewys is dat die akademiese opleiding van kriminoloë in ’n mate ontoereikend is, is vasgestel dat kriminoloë ’n unieke stel vaardighede besit wat hulle in ’n unieke posisie plaas om as deel van ’n multidissiplinêre span verskeie funksies in die kindergeregtigheidsektor uit te voer. Bevindings dui daarop dat die “Child Justice Act” 75 van 2008 gewysig behoort te word om vir die insluiting van kriminoloë in die Suid-Afrikaanse kindergeregtigheidsektor voorsiening te maak. / Sepheo sa phuputso ena ya kutullo le tlhaloso e ne e le ho hlahisa morero wa ketso bakeng sa ditsebi tsa tsa botlokotsebe hore ebe basebetsi ba ikgethang sistiming ya Afrika Borwa ya toka ya bana.

Summaries in English, Afrikaans and Southern Sotho / The aim of this study was to assess the suitability of International Financial Reporting Standards (IFRS) adoption in Ethiopia. To this effect, the study focused on examining the key factors that would influence IFRS adoption in the context of Ethiopia, namely economic growth, economic openness, capital market development, level of accounting education as well as legal systems and government policies. The study used a mixed-method approach, which involved a survey and content analysis. While the survey was the primary research approach in this study, the secondary data analysis was used to obtain additional evidence to corroborate the information gathered through the survey. Descriptive statistics was used to analyse and interpret the data. The study results show that the aforementioned factors examined were not conducive to adopting IFRS, and thus IFRS was not regarded as suitable in Ethiopia at the time of this study. The study also revealed an absence of a single set of accounting standards in Ethiopia. / Die doel van hierdie studie was om die geskiktheid van Internasionale Finansiële Verslagdoeningstandaarde-aanneming (IFRS-aanneming) in Ethiopië te assesseer. Die studie het derhalwe daarop gefokus om die sleutelfaktore te ondersoek wat die IFRS-aanneming in die konteks van Ethiopië sal beïnvloed, naamlik ekonomiese groei, ekonomiese oopheid, kapitaalmarkontwikkeling, vlak van rekeningkundeopvoeding, asook regstelsels en regeringsbeleide. Die studie het ’n gemengdemetodebenadering gebruik, wat ’n ondersoek en inhoudsontleding ingesluit het. Hoewel die ondersoek die primêre navorsingsbenadering in hierdie studie was, is die sekondêre ontleding gebruik om bykomende bewyse te bekom om die inligting wat deur middel van die ondersoek ingesamel is, te bevestig. Beskrywende statistiek is gebruik om die data te ontleed en te interpreteer. Die resultate van die studie dui daarop dat die bogenoemde faktore wat ondersoek is, nie bevorderlik is om die IFRS aan te neem nie en derhalwe is die IFRS as nie geskik vir Ethiopië ten tye van hierdie studie beskou nie. Die studie het ook ’n afwesigheid van ’n enkele stel rekeningkundige standaarde in Ethiopië aan die lig gebring. / Maikaelelo a thutopatlisiso eno e ne e le go sekaseka go tshwanelega ga go amogelwa ga Seemo sa Tlhagiso ya Dipegelo Tsa Ditšhelete sa Boditšhabatšhaba (IFRS) kwa Ethiopia.

Abstract in English, Sepedi and Sesotho / In this thesis, the researcher used an explanatory sequential mixed methods research design to investigate the role of English academic vocabulary on reading comprehension of grade 11 English First Additional Language (EFAL) learners in the Free State province, Fezile Dabi district in South Africa. The current study is an attempt to determine whether the breadth and depth of vocabulary knowledge have a bearing on grade 11 EFAL learners' reading comprehension, and to examine which one of these variables, that is, breadth or depth of vocabulary knowledge, makes a more important contribution to reading comprehension. It also attempts to investigate the Vocabulary Learning Strategies (VLS) used by grade 11 EFAL learners. For the non-experimental quantitative study, the participants of the study were thirty EFAL learners who were chosen based on available sampling. To collect the relevant data, two tests measuring breadth and depth of vocabulary knowledge (Section A and Section B) and a reading comprehension were administered to all participants. To achieve its aim 1, two independent variables namely, the Vocabulary Levels Test (VLT) which measures vocabulary breadth and Word Associate Test (WAT) which measures vocabulary depth were used. Then, the dependent variable was the reading comprehension test in which the participants were asked to read the passages and answer some multiple choice questions. Pearson product-moment correlations and multiple regression were chosen as the dominant techniques for the statistical analyses. The results obtained from the analysis of the data indicated that while both depth and breadth of vocabulary knowledge play an important role in EFAL learners' reading comprehension performance, depth of vocabulary knowledge makes a more important contribution. The results further revealed that depth and breadth of vocabulary knowledge are positively correlated, that is, those learners who had large vocabulary size had a deeper knowledge of the words, too. Then, the findings from the qualitative study based on the data collected through eight focus group discussion participants about the VLS used by grade 11 EFAL learners, highlight that it is important to explore and broaden learners’ vocabulary learning strategic knowledge. Also, results reflect that learners can take control of their own vocabulary learning as long the teachers train and then offer them opportunities to learn and practice the strategies.The qualitative data for this study was analysed using the content analysis method. / Nyakisiso ye e tserwe ka mekgwa ye mentshi ye e hlakantshitsweng lebaka e le go nyakishisha ka karolo yeo polelo ya Sepediya poleloya tlatselletso e ralokang karolo dithutong tsa polelo ya go bala taodiso mphatong wa lesometee (11) polelong go bana kua porofenseng ya Foreistata e bitswang Fezile Dabi, districting (lefapheng) gona mo Aforika Borwa.

Abstract in English, Tswana and Afrikaans / People who graduated from higher education, whether they attended classes on campus or studied via a distance mode of learning, have not only been educated but are also able to participate in and contribute positively to the political, social and economic forums in their immediate environments and within their country. Progressing through the higher education system successfully is not easy since there are many challenges to overcome. Students With Disabilities (SWD) face even greater challenges in making their way through the system to emerge triumphantly as graduates. Institutions of higher learning, including Open Distance eLearning (ODeL) facilities, must provide support to SWD in order to facilitate their learning experience so that they are better equipped to succeed. Therefore, it is vital to promote access to higher education for people with disabilities and to provide support, such as making assistive technologies and human services available, for SWD within ODeL institutions. This qualitative study was exploratory in nature and used a multiple case study research design in the chosen area to investigate the provision of support for SWD in the ODeL institution. Data were collected by means of semi-structured interviews and a document analysis, and these two methods of data gathering assisted with triangulation. The research findings revealed differences between the findings that were obtained through the responses received from teacher and staff member participants. The research findings also revealed differences between the findings that were obtained through the responses received from the participants, in general, and those obtained through the document analysis. The findings obtained through responses received from teacher participants showed that support for SWD was more evident at the school level than at the ODeL institution, that is, at the tertiary level of education. The document analysis of the policies of the ODeL institution revealed that the policies were general and did not specifically relate to the needs of SWD. At the same time, the findings in this dissertation of limited scope showed that the use of technology and the availability of assistive devices were more prominent at the school level than at the ODeL institution. / Batho ba ba alogang go tswa mo ditheong tse kgolwane tsa Thuto, ba tswa ba ka bo ba rutilwe le go ithuta ka go tsenela dikamuso (attending lecturers) mo khemphaseng kgotsa ba rutilwe le go ithuta ka thutotlhaeletsano, ga ba rutega fela mme ba kgona gape le go nna le seabe le go abelana ka tshiamo mo diforamong tsa sepolotiki, tsa seloago le tsa seikonomi mo ditikologong tse ba iphitlhelang ba le mo go tsona naga ka bophara.

Dit is nie maklik om suksesvol deur die hoëronderwysstelsel te vorder nie, omdat daar baie struikelblokke is om te oorkom. Studente met gestremdhede (SMG) het selfs meer uitdagings om hul weg deur die stelsel te baan en triomfantlik as graduandi te verrys. Hoëronderriginstellings, insluitende oop e-afstandsleer (ODeL) -fasiliteite, moet ondersteuning aan SMG bied om hul leerervarings te fasiliteer sodat hulle beter toegerus is om sukses te behaal. Dit is daarom noodsaaklik om toegang tot hoër onderwys en ondersteuning aan mense met gestremdhede te bied, soos om hulptegnologieë en menslike dienste aan SMG in ODeL-instellings beskikbaar te stel. Hierdie kwalitatiewe studie was verkennend van aard en het 'n veelvoudige gevallestudie-ontwerp in die gekose veld gebruik om die voorsiening van ondersteuning aan SMG in 'n ODeL-instelling te ondersoek. Data is versamel deur semigestruktureerde onderhoude en 'n dokumentonleding; hierdie twee metodes van dataversameling het met triangulasie gehelp. Navorsingsbevindings het verskille aangedui tussen die data wat verkry is van die onderwyser en die van deelnemende personeellede se reaksies. Navorsingsbevindings het ook verskille aangedui tussen die data wat verkry is van deelnemers se reaksies oor die algemeen en die wat deur dokumentontleding verkry is. Die bevindings wat deur die onderwyserdeelnemers verkry is, het aangedui dat ondersteuning aan SMG duideliker op skoolvlak was as by die ODeL-instelling; dit is op tersiêre vlak van onderwys. Die dokumentontleding van die ODeL-instelling se beleide het aangedui dat die beleide algemeen was nie spesifiek met SWD se behoeftes verband hou nie. Terselfdertyd het die bevindings van hierdie verhandeling van beperkte omvang getoon dat die gebruik van tegnologie en die beskikbaarheid van hulptoestelle meer prominent was op skoolvlak as by die ODeL-instelling. / Curriculum and Instructional Studies / M.
