Thesis (MPhil)--Stellenbosch University, 2014. / ENGLISH ABSTRACT: The aim of this thesis is to establish a tangible metric by which to evaluate the impact of modern energy access on the livelihoods of rural Sub-Sahara African communities. The narrative is set in Tsumkwe, a remote rural Namibian location some 596 km north-east from the main capital city Windhoek. Initiatives aimed at rural electrification and energy provision are expected to reduce poverty as well as contribute to the community’s general wellbeing. However, determining the relationship between energy and development is quite a challenging undertaking. An analysis that is either exclusively quantitative or qualitative runs the risk of providing a skewed picture of the energy-development-poverty nexus. In this thesis, quantitative data is embedded within qualitative data as an attempt to examine the nexus and to translate how intervention programmes are transformed into outcomes in order to gauge success of a project. The transformative paradigm shaped the theoretical framework and informed the mixed-method research approach while the capability approach was used to analyse plurality and individualisation of policy impacts. Consequently, the role of place is positioned at the centre in gauging experiences of the poor vis-à-vis the importance of locating resources and capabilities to address socio-economic issues within a geographical location. The injustice of energy poverty can be viewed as unequal access to energy services (i.e. distributional injustice) as well as an intervention that failed to recognise the needs of certain groups and potentiality offered by place. From this, the concept of an energy poverty penalty is qualitatively developed. It was found that the penalty, although it is more pronounced in the low income groups, is exacerbated by choice offered in an energy basket thus affecting non-income poor households too. Therefore, the energy poor are not necessarily income-poor. It is finally concluded that while sustainable energy interventions offer the possibility to reduce energy poverty and the attendant human wellbeing index improvement they need to be grounded in a robust information base to track progress towards targets. Most existing indicators and composite indices assessing access to energy, the degree of development related to energy and deprivation of access to modern energy fail to account for the energy poverty trap. / AFRIKAANSE OPSOMMING: Die doel van hierdie tesis is om ‘n tasbare meting daar te stel om die impak to toegang to moderne energie daar te stel in landelike gebied in sub-Sahara Afrika te evalueer. Die studie is uitgevore in Tsumkwe, ‘n afgeleë landelike gebied in Namibië, sowat 596 km noordoos van die hoofstad, Windhoek. Daar word veronderstel dat inisiatiewe wat daargestel word om energie en elektrisiteit toeganglik te maak vir landelike gebiede en gemeenskappe, verarming sal teewerk en gemeenskappe kan ophef. Dit is egter moelik om die verhouding tussen energie verskaffing and vooruitgang te bepaal. ‘n Studie wat net kwalitatief of kwantitatief gebaseer is, sal nie die ware toedrag van sake uitlig nie. In hierdie tesis is kwalitatiewe data verweef met kwantitatiewe data om vas te stel presies hoe effektief programme is wat daargestel is om energie aan landelike gebiede te lewer. Die transformatiewe paradigma het die teoretiese raamwerk gevorm en gelei tot die kombinasiemetode navorsingsbenadering terwyl die moontlikheids benadering gebruik is om die pluraliteit en individualisering van die beleidsimpakte te ontleed. Gevolglik, is die rol van plek in die middelpunt van die ondervindings van die armes vis-à-vis die belangrikheid van die verkryging van hulpbronne en vermoë om sosio-ekonomiese kwessies binne ‘n geografiese ligging te hanteer. Die feit dat landelike gebiede verarm is wat energie en elektrisiteit voorsiening betref, kan toegeskryf word aan die volgende: ongelyke toegang to energie dienste, programme wat nie die behoeftes van landelike gemeenskappe aanspreek nie en die potensiaal van plek waar die program aangepak word is nie voldoende aangespreek nie. In die lig van hierdie potensiële oorsake van energie verarming is die konsep energie aarmoede boete kwaliteitsgewys ontwikkel. Dit is gevind dat die boete, wat meer van toepassing is op lae inkomste groep is, beinvloed word deur die keuse wat beskikbaar gemaak is in terme van energie voorsiening. Hierdie keuse het ook ‘n invloed op die “geen-inkomste” arm groep in ‘n gemeenskap. Dit is dus duidelik dat diegene wat energie verarm nie noodwending geldelik ook verarm is nie. Die studie, ter opsomming, het tot die slotsom gekom dat hoewel tussenkomende programme wat daar gestel word om volhoubare projekte aan te bied vir energie voorsiening in landelike gebiede, energie verarming kan verminder, dit nie effektief genoeg is tensy dit opgevolg word met duidelike doelwitte nie. Die bestaanded aanduidings vir toegang tot energie, aanduidings wat energie toegang en vooruitgang evalueer is nie werklik effektief genoeg nie.

Thesis (MAud)--Stellenbosch University, 2015. / ENGLISH ABSTRACT: In developing countries, like Namibia, there is limited data pertaining to the number of individuals with hearing loss and its associated factors. This study aimed to determine the prevalence of potential hearing loss in Namibian Class A mines and to describe the extrinsic and intrinsic factors associated with hearing loss. A cross-sectional design was utilised and data were collected from 132 respondents (mining employees) from five different Class A mines throughout the country. A questionnaire and a retrospective review of respondents’ medical records were utilised to determine the risk factors. The most recent audiogram found in the respondents’ records was used to determine the presence of potential hearing loss. Three definitions of potential hearing loss were used in this study and included all major frequency hearing loss (AFHL), high frequency hearing loss (HFHL) and low frequency hearing loss (LFHL). Potential hearing loss was identified when the pure tone average (PTA) of 0.5, 1, 2, & 4kHz, 0.5, 1 & 2kHz and 4 & 8kHz respectively was greater than 25dBHL in either one or both ears. Chi-square measurements or, where necessary, Fisher’s exact tests, as well as Odds Ratios were used for the analysis of data. In general a significance level of 5% was applied for all analyses. Results indicated the prevalence of potential hearing loss in Namibian mining employees to be 27% and that both extrinsic and intrinsic factors were associated with hearing loss. The extrinsic factors significantly associated with potential hearing loss were both occupational and medical. The occupational factors found to be significant were the number of years employed in whole life >10 years (p=0.012; OR=3.1, 95% CI=1.3-7.9), the number of years employed in current job > 10 years (p=0.01; OR=3.9, 95% CI1.7-8.8) and the non-availability of formal training in prevention of hearing loss (p=0.022; OR=0.3, 95% CI (0.1-0.9). Diabetes was the sole significant extrinsic medical factor (p=0.035, OR=5, 95% CI 1.1-22.1). The only intrinsic factor which was found to be significantly associated with hearing loss was Age, specifically being older than 40 years (p=0.002; OR=3.5, 95% CI 1.6-7.8) and 50 years (p=0.001, OR=5.5, 95% CI1.9-15.8). A multiple logistic regression model of all significant factors found that only no formal training of prevention of hearing loss was found to be significant in the presence of all other factors (p=0.036, OR=0.036, 95% 0.1-0.92). Findings from this study suggest that multiple factors may be associated with potential hearing loss and not just the exposure to hazardous occupational conditions. Recommendations for future research and clinical practice should, therefore, include thorough investigations into the aetiology of hearing loss. As this study focused on Class A mines, it is recommended that future research be conducted in other mines that are not categorised as Class A mines. Keywords: prevalence, extrinsic factors, intrinsic factors, extrinsic occupational factors, extrinsic social factors, extrinsic medical factors, potential hearing loss, mining industry, Class A mine, Namibia. / AFRIKAANSE OPSOMMING: In ontwikkelende lande, soos Namibië, is daar beperkte data met betrekking tot die aantal individue met gehoorverlies en sy verwante faktore. Hierdie studie het gepoog om die voorkoms van gehoorverlies in Namibiese Klas A myne te bepaal en die ekstrinsieke en intrinsieke faktore wat verband hou met potensiale gehoorverlies te beskryf. 'n Deursnee-ontwerp is gebruik en data is ingesamel uit 132 respondente (mynbou werknemers), uit vyf verskillende Klas A myne regdeur die land. 'n Vraelys en 'n retrospektiewe oorsig van die respondente se mediese rekords is gebruik om die risiko faktore te bepaal. Die mees onlangse oudiogram wat in die respondente se rekords gevind is, is gebruik om die teenwoordigheid van potensiale gehoorverlies te bepaal. Drie definisies van potensiale gehoorverlies is gebruik in hierdie studie, ingesluit al die groot frekwensie gehoorverliese (AFHL), hoë frekwensie gehoorverlies (HFHL) en 'n lae frekwensie gehoorverlies (LFHL). ‘n Gehoorverlies was teenwoordig wanneer die suiwer toon gemiddelde (PTA van 0.5 , 1 , 2, & 4kHz , 0.5, 1 & 2kHz en 4 & 8kHz onderskeidelik , groter was as 25dBHL in een of albei ore. Chi -square metings of, waar nodig, Fisher se presiese toetse, asook kans verhoudings is gebruik vir die ontleding van data. In die algemeen is 'n beduidendeidsvlak van 5% gebruik en toegepas vir al die ontledings. Resultate het aangedui die voorkoms van gehoorverlies in Namibiese mynbouwerknemers tot 27 % was en dat beide ekstrinsieke en intrinsieke faktore ‘n verband toon met potensiaal gehoorverlies. Die ekstrinsieke faktore wat ‘n beduidende verband getoon het met gehoorverlies was albei beroeps- en mediese faktore. Die beroepsfaktore wat betekenisvol was, was die aantal jare diens in hele lewe > 10 jaar ( p = 0,012 ; OR = 3.1 , 95 % CI = 1.3-7.9) , die aantal jare in huidige pos> 10 jaar diens (p = 0,01 ; OF = 3.9 , 95 % CI1.7-8.8 ) en die onbeskikbaarheid van formele opleiding in die voorkoming van potensiaal gehoorverlies (p = 0,022 ; OF = 0,3 , 95 % CI ( 0,1-0,9 ). Diabetes was die enigste beduidende ekstrinsieke mediese faktor (p = 0,035 , OR = 5 , 95 % CI 1,1-22,1 ). Die enigste intrinsieke faktor watbeduidend was en verband hou met gehoorverlies was ouderdom, spesifiek om ouer as 40 jaar ( p = 0,002 ; OF = 3.5 , 95 % CI 1,6-7,8 ) en 50 jaar ( p = 0.001 , OR = 5.5 , 95 % CI1.9-15.8 ) te wees. 'n Veelvuldige regressie model van alle beduidende faktore het bevind dat slegs geen formele opleiding in die voorkoming van gerhoor verlies beduidende was in die teenwoordigheid van al die ander faktore ( p = 0,036 , OR = 0,036 , 95 % 0,1-0,92 ) . Bevindinge van hierdie studie dui daarop dat verskeie faktore geassosieer kan word met gehoorverlies en nie net die blootstelling aan gevaarlike beroepstoestande nie. Aanbevelings vir toekomstige navorsing en kliniese praktyk moet dus 'n grondige ondersoek na die etiologie van gehoorverlies uitvoer. Aangesien hierdie studie gefokus het op die Klas A- myne , word dit aanbeveel dat toekomstige navorsing gedoen word in ander myne wat nie gekategoriseer is as Klas A myne nie. Sleutelwoorde: Voorkoms, ekstrinsieke faktore, instrinsieke faktore, ekstrinsieke beroepsfaktore, ekstrinsieke sosiale faktore, ekstrinsieke mediese faktore, potensiale gehoorverlies, Klas A myn, Namibië.

Thesis (MBA)--Stellenbosch University, 2001. / ENGLISH ABSTRACT: The Republic of Namibia gained its independence from South Africa on 21 March 1990. The divided economic sector between modem European orientated and the underdeveloped African sector places major challenges on the government, the business sector and on the population itself. Vast differences exist between income, educational level, and living conditions and life expectations. The economy can be described as stable. Mining, fishing and agriculture are the main contributors to the economy. Currently the government maintains a budget deficit of 23.5% of the Gross Domestic Product. The economic policy can be described as open and democratic. Exchange rates and interest rates are market-determined. The comparatively high Gini - Coefficient of 0,7%, an unemployment rate of 34% and the decrease of the life expectancy rate are major challenges faced by the government of the day. Since independence Namibia has become a member of many regional and world organisations. These organisations support Namibia in various development projects, which will contribute t a stable economy. The composition of the Namibian population together with the size of the country and its various natural resources makes Namibia not very attractive for major manufacturers or industrialisation. Therefore the development of Small Macro and Medium Enterprises are of utmost importance. Namibia has developed a sophisticated financial sector, compared to other African countries. The Namibian Stock Exchange was established during 1992 and has developed into the second largest stock exchange in Africa. Treasury Bills and Government Bonds have been introduced as investment tools. Various state-supported institutions have been founded to support economic development. The Ministry of Trade and Industry implemented various tax incentives to attract foreign and local investments. However these measures have not had the expected effect. Namibia can learn few things from Mauritius, which has had basically the same historical development and economic composition. To ensure future investments in Namibia the government should consider the implementation of an investment tax, the implementation of an Unemployment Insurance Fund, and the support of unemployed people. The effect of HIV/AIDS will have a major impact on the economy of the country. The regional development will have a major effect on the national economy. The Southern African Development Community should create a regional currency, a standard economic and political structure and a free trade area. Such a regional development will have a positive effect on all national economies. Namibia has enough investment opportunities for national and foreign investors. Political and economical stability has to be maintained to ensure continuous future support of the investors. To fight poverty additional steps have to be taken so that within 20 years poverty in Namibia is not an issue anymore. / AFRIKAANSE OPSOMMING: Die Republiek van Namibië het op 21 Maart 1990 onafhanklik geword. Die groot ekonomiese verskille tussen moderne Europese en ander ontwikkelde Afrikaanse sektore plaas die regering, die besigheids sektor en die inwoners voor 'n groot uitdaging. Groot verskille bestaan tussen inkomste, opvoeding, lewens omstandighede en verwagte lewensduur. Die ekonomie kan as stabiel beskryf word. Huidiglik handhaaf die regering 'n begrotingstekort van 23.5% van die Nasionale Bruto Binnelandse Produk. Die ekonomiese beleid kan as demokraties en oop beskryf word. Die wisselkoerse en rentekoerse word deur die mark bepaal. Die relatief hoë Gini koefisiënt van 0.7%, 'n werkloosheidspersentasie van 34% en 'n daling in die verwagte lewensduur stel die regering voor 'n groot uitdaging. Sedert onafhanklikheid het Namibië lid geword van talle streeks- en werêld organisasies. Hierdie organisasies ondersteun Namibië in verskillende ontwikkelingsprojekte, wat 'n stabiele ekonomie tot gevolg sal hê. Die samestelling van die bevolking van Namibië en die grootte van die land tesame met die natuurlike hulpbronne maak dit aanloklik vir groot fabrieke en industrieë. Die ontwikkeling van mikro en klein besighede is dus uiters belangrik. Namibië het 'n gesofistukeerde finansiële sektor in vergelyking met ander Afrika lande ontwikkel. Die Namibiese effektebeurs is 1992 in die lewe geroep en het tot die tweede grootste effektebeurs in Afrika ontwikkel. Skatkis briewe en regerings skuldbriewe is ingevoer as beleggings moontlikhede. Verskillende regerings en ondersteunende instansies het onstaan om ekonomiese ontwikkelling te bevorder. Die Ministerie van Handel en Ontwikkeling het verskillende belasting voordele geskep om buitelandse beleggers te trek. Tot op die huidige dag het hierdie voordele nie die gewensde effek gehad nie. Namibië kan baie van Mauritius leer, wat basies dieselfde historiese ontwikkeling gehad het en dieselfde ekonomiese samestelling het. Om toekomstige ontwikkeling te verseker, behoort die regering die implementering van 'n beleggersbelasting te oorweeg, sowel as 'n werkloosheidsversekeringsfonds om werklose mense te help ondersteun. Die effek van MIV/VIGS sal 'n groot uitwerking hê op die ekonomie van die land. Streeksontwikkeling in Suider-Afrika sal 'n groot effek op die ontwikkelling van die nasionale ekonomie hê. Die Suid Afrikaanse Ontwikkelings Vereniging behoort een gesamentlike geldeenheid, 'n standaard ekonomiese en politieke beleid te hê om 'n vrye handelssone te implementeer. Die streeksontwikkeling sal 'n positiewe effek op alle nasionale ekonomieë hê. Namibië het genoeg beleggingsmoontlikhede vir nasionale en buitelandse ontwikkellaars. Politieke en ekonomiese stabiliteit behoort gehandhaaf te word om toekomstige steun van beleggers te waarborg. Om armoede te bekamp, moet addisionele stappe geneem word om te verseker dat dit oor 20 jaar geen probleem meer sal wees nie.

ENGLISH ABSTRACT: In Namibia the small business sector is seen to play a very important role in the creation of jobs and the growth of the economy. At the same time small enterprises face a wide range of problems, which keep the failure rates of new ventures high and often prevent dynamic business growth. To address these challenges it is insufficient to have a national strategy for small businesses or to just rely on national government and other national bodies. This is particularly important in a country like Namibia which has a small population, stretched over a vast territory, with huge differences in the resources and development patterns of the various regions. Against that background this study focuses on a particular area of Namibia, viz the Erongo Region along the coastal belt. It is Namibia’s best developed region after the central Windhoek/Khomes area, with the two towns, Walvis Bay and Swakopmund, the harbor of Walvis Bay, the Uranium mines and tourism being the foundation for business growth. After reviewing the spectrum of small business support bodies available in Namibia the study looked at a sample of 100 small enterprises in the Erongo area. They were asked about their business engagement, business prospects, main problems experienced and their awareness and utilization of support programmes. These needs profiles were then compared to the set of actual service suppliers found in the Erongo region. This showed that in practice very few of the problems are addressed, largely due to a lack of awareness, pro-activity and cooperation on both sides: local small enterprises and local support suppliers. The study ends with a range of proposals which should, if tackled on a partnership basis and in closer cooperation between the head offices in Windhoek and local bodies, lead to a steady improvement of the SME support process.

Main attention was given to the relatively unexplored field of spatial and structural organisation of the primary producer component in relation to its quantified intra-seasonal functional changes including its phenology. Simple mathematical model descriptions of seasonal mass change of the herbaceous parts of the primary producer component were derived. Various parts of the primary producer component were also evaluated in terms of some of the main climatic driving forces of the ecosystem, decomposition relations in the form of disappearance rates, soil-vegetation mineral relations and consumer (mainly insect) relations. Gross effects of manipulation of the ecosystem type by fire and management is included.

Pre-eclampsia is a multi-organ system disorder that occurs after the 20th week of gestation in pregnancy and is characterized by hypertension and proteinuria with or with out oedema. It is a major cause of morbidity and mortality for the woman and her child. Based on surveillance data, pre-eclampsia is one of the leading causes of maternal mortality in Namibia. However, there is no depth study done in Namibia that looks at the extent of confirmed pre-eclampia and its contribution to maternal and perinatal morbidity and mortality. There is also no standard management protocol currently recommended in Namibia. The aim of this study was to evaluate the outcomes and quality of care given to pre-eclamptic patients treated in Windhoek Central and Katutura referral hospitals in Namibia within the period of January 2003 to December 2004.
