This thesis identifies realistic export opportunities for South African products in the rest of the world and specifically in the rest of the African continent. The method chosen to achieve this goal is the Decision Support Model (DSM) developed by Cuyvers et al (1995) and Cuyvers (1997) that was specifically designed to assist export promotion institutions in planning and assessing their export promotion activities. This model is positioned into the international market selection literature and four main refinements to the DSM methodology are introduced to address the limitations of the model and to make it more applicable for the South African international trade conditions. The refined model is then applied to identify product–country combinations with the largest export potential for South Africa in the rest of the world and in the rest of the African continent specifically. The refinements to the DSM filtering process introduced in this study contribute to the effective use and application of the DSM results by South African exporters and more focused export promotion activities by South African export promotion organisations. The four refinements include (i) running the DSM on a HS 6–digit level, (ii) introducing a method to calculate the potential export value of each identified export opportunity in order to prioritise between the product–country combinations identified as realistic export opportunities, (iii) taking the production capacity of South Africa into consideration in order to identify export opportunities that can be pursued immediately due to the country's existing revealed comparative advantage in the production and exportation of these products and (iv) developing a market accessibility index per product–country combination from a South African point of view on a HS 6–digit level in order to make filter 3.2 (barriers to trade) of the DSM applicable for South African conditions. The results of the application of the refined DSM to identify export opportunities for South Africa in the rest of the world include the top 50 worldwide export opportunities. There are 17 countries in which the top 50 worldwide product–country combinations identified as export opportunities for South Africa are located. These include the United States, Japan, India, the United Kingdom, Canada, China, Germany, Israel, Hong Kong, the Netherlands, Australia, Belgium, Singapore, Indonesia, Saudi Arabia, Italy and Brazil. Mineral products (coal, copper and aviation spirit); transportation products (1500 - 3000 cc automobile engines and diesel powered trucks); stone/glass (diamonds, platinum and rhodium) and metals (aluminium, iron/steel structures, nickel) are the product classifications within the top 50 worldwide product–country combinations that hold the largest worldwide export potential for South Africa. In terms of the product–country combinations with the highest export potential for South Africa in the rest of the African continent, there are 18 countries in which the top 50 product–country combinations for South Africa in the rest of the African continent are located. These include Nigeria, Namibia, Ghana, Morocco, Egypt, Zambia, Tunisia, Kenya, Uganda, Zimbabwe, Botswana, Mauritius, Tanzania, Senegal, Mozambique, Algeria, Malawi and Cote d'Ivoire. The products with the highest potential export values in the top 50 product–country combinations for South Africa in Africa include mineral products (aviation spirit, iron ore, sulphur and coal) and transportation products (1500 - 3000 cc automobile engines and diesel powered trucks weighing less than 5 tons). / Thesis (Ph.D. (International Trade))--North-West University, Potchefstroom Campus, 2011.

SMEs can play a significant role in the economy as drivers of economic growth and job creation. Many SMEs are, however constrained by their limited access to finance. This study examines the source of finance of firms in South Africa and estimates the importance of finance as a predictor of output per worker. Using the 2007 World Bank Enterprise Survey, the study focuses on the firm’s access to finance, or sources of finance, as a predictor of the productivity of South African firms. Other factors that are taken into account include sources of finance such as the overdraft of the firm, collateral available and the type of financial institution used to acquire financing. These covariates all play an integral role in whether or not the firm will receive the financing, the amount granted and the repayment terms. Empirical analysis is done with a Cobb–Douglas production function regression to determine how output per worker is influenced by various factors. The results show that output per worker improves as additional finance variables are added to the regression model. Using an access to finance dummy as the dependent variable, a logistic regression model is used to calculate the probability of access to finance as a constraint based on the independent variables. The results of the logistic regression show that the probability of firms’ experiencing access to finance as a constraint is decreased by variables such as fixed assets and increase with negative factors such existing debt and collateral. These results are expected based on previous research on the topic and confirms that access and finance sources are determinants for firm growth. Recommendations include more extensive research on the topic, with panel data over a longer period and specific to a country. Policy recommendations include amended evaluation techniques, adapted to the individual firm’s requirements and strengths. / Thesis (M.Com.

In order to make decisions to approve filling stations, an environmental impact assessment (EIA) needs to be conducted and evaluated by the competent authority. Although numerous filling stations have been authorised for operation, the quality of the EIA reports that form the basis for decision making has never been evaluated. The evaluation of the quality of EIA reports on filling station developments by means of an adapted Lee–Colley review package formed the basis of this research. The main conclusion was that the quality of the EIA reports for filling station developments, as reviewed by the adapted review package, is generally of a poor standard. This means that a decision to approve a new filling station is generally based on just enough information to the competent authority. The main deficiencies in the EIA reports related to site description, cumulative impacts and mitigation measures, while the environment description, identification of impacts, scoping of impacts, assessment of impact significance and emphasis (impacts) in the reports were of good quality. The results from the reviewed EIA’s correspond mostly with the literature on the review of EIA reports. / Thesis (M. Environmental Management)--North-West University, Potchefstroom Campus, 2012.

Tourism is currently the third largest industry within South Africa. Many African countries, including South Africa, have the potential to achieve increased economic growth and development with the aid of the tourism sector. As tourism is a great earner of foreign exchange and also creates employment opportunities, especially low–skilled employment, it is identified as a sector that can aid developing countries to increase economic growth and development. Accurate forecasting of tourism demand is important due to the perishable nature of tourism products and services. Little research on forecasting tourism demand in South Africa can be found. The aim of this study is to forecast tourism demand (international tourist arrivals) to South Africa by making use of different causal models and to compare the forecasting accuracy of the causal models used. Accurate forecasts of tourism demand may assist policy–makers and business concerns with decisions regarding future investment and employment. An overview of South African tourism trends indicates that although domestic arrivals surpass foreign arrivals in terms of volume, foreign arrivals spend more in South Africa than domestic tourists. It was also established that tourist arrivals from Africa (including the Middle East), form the largest market of international tourist arrivals to South Africa. Africa is, however, not included in the empirical analysis mainly due to data limitations. All the other markets namely Asia, Australasia, Europe, North America, South America and the United Kingdom are included as origin markets for the empirical analysis and this study therefore focuses on intercontinental tourism demand for South Africa. A review of the literature identified several determinants of tourist arrivals, including income, relative prices, transport cost, climate, supply–side factors, health risks, political stability as well as terrorism and crime. Most researchers used tourist arrivals/departures or tourist spending/receipts as dependent variables in empirical tourism demand studies. The first approach used to forecast tourism demand is a single equation approach, more specifically an Autoregressive Distributed Lag Model. This relationship between the explanatory variables and the dependent variable was then used to ex post forecast tourism demand for South Africa from the six markets identified earlier. Secondly, a system of equation approach, more specifically a Vector Autoregressive Model and Vector Error Correction Model were estimated for each of the identified six markets. An impulse response analysis was undertaken to determine the effect of shocks in the explanatory variables on tourism demand using the Vector Error Correction Model. It was established that it takes on average three years for the effect on tourism demand to disappear. A variance decomposition analysis was also done using the Vector Error Correction Model to determine how each variable affects the percentage forecast variance of a certain variable. It was found that income plays an important role in explaining the percentage forecast variance of almost every variable. The Vector Autoregressive Model was used to estimate the short–run relationship between the variables and to ex post forecast tourism demand to South Africa from the six identified markets. The results showed that enhanced marketing can be done in origin markets with a growing GDP in order to attract more arrivals from those areas due to the high elasticity of the real GDP per capita in the long run and its positive impact on tourist arrivals. It is mainly up to the origin countries to increase their income per capita. Focussing on infrastructure development and maintenance could contribute to an increase in future tourist arrivals. It is evident that arrivals from Europe might have a negative relationship with the number of hotel rooms available since tourists from this region might prefer accommodation with a safari atmosphere such as bush lodges. Investment in such accommodation facilities and the marketing of such facilities to Europeans may contribute to an increase in arrivals from Europe. The real exchange rate also plays a role in the price competitiveness of the destination country. Therefore, in order for South Africa to be more price competitive, inflation rate control can be a way to increase price competitiveness rather than to have a fixed exchange rate. Forecasting accuracy was tested by estimating the Mean Absolute Percentage Error, Root Mean Square Error and Theil’s U of each model. A Seasonal Autoregressive Integrated Moving Average (SARIMA) model was estimated for each origin market as a benchmark model to determine forecasting accuracy against this univariate time series approach. The results showed that the Seasonal Autoregressive Integrated Moving Average model achieved more accurate predictions whereas the Vector Autoregressive model forecasts were more accurate than the Autoregressive Distributed Lag Model forecasts. Policy–makers can use both the SARIMA and VAR model, which may generate more accurate forecast results in order to provide better policy recommendations. / Thesis (M.Com.

Die historiese wortels van apartheid is vasgele in die tydperk tussen 1652 en 1948. Die Ned. Geref. Kerk het vanaf die dertigerjare van die twintigste eeu die regering versoek om apartheid statuter uit te bou. Met die bewindsverandering in 1948 het 'n nuwe fase van meer as veertig jaar in Suid-Afrika aangebreek. Gedurende hierdie tydperk vind ons 'n hegte band tussen die owerheid en die Ned. Geref. Kerk. Die Ned. Geref. Kerk het in 1948 apartheid vanu it die Skri f geregverd i g en het sy profetiese getuienis daarmee sterk onder verdenking gebring. Die statutere implementering van apartheid het hierna gevolg. Die Ned. Geref. Kerk en die owerheid het hulle standpunte gegrond op die beginsel van voogdyskap. Hiervolgens was blankes die voogde van nie-blankes wat hulle tot mondigheid moet begelei. Na republiekwording is die tuislandbeleid ontwikkel sodat swartmense onafhanklikheid kon verkry. In die praktyk het swartes afhanklik en ondergeskik aan blankes gebly. In 1974 verskyn Ras, Volk en Nasie as amptelike beleidsdokument van die Ned. Geref. Kerk. Die Skriftuurlike begronding verdwyn en apartheid word om praktiese redes onderskryf. Die onluste van 1976 het 'n fase van kritiese evaluering van apartheid ingelei. Die regering het begin om toegewings oor apartheid te maak. As gevolg van die diep kloof tussen politieke oortuigings van Ned Geref. Kerklidmate was die vroee tagtigerjare 'n fase vol huiwering vir die Ned. Geref. Kerk oor apartheid. Die besluit tydens die Algemene Sinode van 1986 dat die Ned. Geref. Kerk "oop" is, was in beginsel 'n sprong weg van apartheid soos gereflekteer in die nuwe beleidsdokument, Kerk en Samelewing. In die fase tussen 1986 en 1991 vind die besliste ontstrengeling van apartheid plaas. Die Ned. Geref. Kerk en die owerheid het dus saam apartheid geimplementeer en saam daarvan weg beweeg. Die Ned. Geref. Kerk het met sy ondersteuning van apartheid en hegte band met die owerheid meegewerk om sy baie "bevoorregte" posisie ten opsigte van die owerheid ongedaan te maak. 'n Era is afgesluit en in die nuwe Suid-Afrika is daar nou 'n nuwe owerheid met nuwe vennote. Indien die Ned. Geref. Kerk nuwe geleenthede aangryp, kan sy Skriftuurlike opdrag, met 'n duidelike profetiese stem, 66k teenoor die owerheid, gehoor word. Die alternatief is 'n eensame pad ... / Thesis (DD)--University of Pretoria, 1994. / gm2014 / Practical Theology / Unrestricted

In Januarie 1914 het ‘n algehele industriële staking in die Unie van Suid-Afrika (SA) uitgebreek en die Unieverdedigingsmag (UVM) sou vir die eerste keer operasioneel aangewend word om die staking te onderdruk. Die Staande mag van die UVM was nog nie gereed om die staking op hul eie te onderdruk nie en gevolglik is die kommando’s van die Burgermagreserwes opgekommandeer vir diens. Probleme is dus destyds met die samestelling en organisasie van die UVM, as gevolg van die intergrasie van die verskillende militêre kulture, ondervind. Die Unieregering het op baie van die gewone burgers wat in die Anglo-Boereoorlog (ABO) in kommando’s geveg het, se ondersteuning en deelname om die staking te onderdruk, staatgemaak. Die tradisionele kommandostelsel van die voormalige Boererepublieke sou dus vlugtig tydens die 1914-staking herleef. Die Afrikaner het as gevolg van verskeie redes op kommando gegaan om die staking te help onderdruk. Die groeiende gees van nasionalisme onder die Afrikaner kon ook tydens die staking waargeneem word en sou tesame met die suksesvolle aanwending van die kommando’s tydens Januarie 1914 bydra tot die Rebellie later die jaar. Die politieke, ekonomiese en sosio-maatskaplike omstandighede van destyds het tot die nywerheidstaking van Januarie 1914 bygedra. Die rol wat die vakbonde en mynbedryf in die tydperk voor die Eerste Wêreldoorlog gespeel het, het ook bygedra tot die staking. Die ervaringe en omstandighede van die kommandolede tydens ontplooiing in Januarie 1914 is ‘n belangrike aspek van die sosiale militêre geskiedskrywing in SA. Onderwerpe soos, mobilisasie, voorrade, vervoer, dissipline, asook demobilisasie en kompensasie werp dus lig op die ervaringe en omstandighede van gewone burgers op kommandodiens tydens die staking. Die aanwending van die kommando’s tydens die 1914-staking het uiteenlopende reaksies van die verskillende groepe in die gemeenskap tot gevolg gehad. Die betrokkenheid van ander rolspelers, soos swart mense en vrouens, tydens die staking was gering, dog belangrik vir die Suid-Afrikaanse geskiedenis.

South Africa has the highest prevalence of Foetal Alcohol Spectrum Disorders (FASD) worldwide. Despite the high prevalence of FASD in children and the resulting need for services, appropriate identification and management of most genetic and congenital disorders are critically lacking in South Africa. As a result of the established risk for communication delay from birth, young children with FASD need early communication intervention (ECI). There appears to be a dearth in research on the communication difficulties of local young children with FASD. Determining comprehensive communication profiles of young children may serve to emphasize their need for ECI. The main aim of the study was to present the distinctive communication profiles of a group of young children with FASD. The sub-aims entailed the description of their developmental histories, family/care-giving contexts, communication functioning and identifying developmental trends across the participants. A collective case study design following a quantitative approach was selected. The study was cross-sectional and descriptive statistics was used to describe the participants’ communication skills. A purposive sampling procedure was utilized as a limited number of participants could be found with a diagnosis of FASD. Five participants diagnosed with FASD, living in the Gauteng area, between the ages of 4 to 58 months took part in the study. The empirical study comprised of two phases. Phase 1 entailed the development of the Interview Schedule, the Assessment Protocol and the conduction of a pilot study. Phase 2 comprised the data collection, analysis and interpretation of results. The results of the study indicated that all five participants presented with incomplete case histories obtained from the foster parents and general developmental delays. According to the Four-Level Early Communication Assessment Framework the greatest delays included all aspects of communication skills. A developmental trend of the combined communication profiles of the participants indicated an increase in delay with an increase in chronological age. The participants presented with complex multiple neuro-developmental needs to be viewed within a developmental systems and ecological framework. Based on the results of this study the diverse roles of the speech-language therapist working with young children with FASD and their families were identified. A framework for interdisciplinary service delivery to this population was suggested. The study succeeded in the attempt to provide a comprehensive, in-depth description of a group of the five participants’ unique communication skills. In addition the study also highlighted the shortage of services, e.g. limited early identification and services dedicated to families affected by alcohol related problems. The study is of value to the speech-language therapist in the clinical and research domain. Future research is recommended to expand and support the findings. AFRIKAANS : Suid-Afrika vertoon die hoogste prevalensie van Fetale Alkohol Spektrumafwykings (FAS) wêreldwyd. Ten spyte van die hoë prevalensie van FAS in kinders en die voortspruitende behoefte aan dienste, is toepaslike identifikasie en hantering van die meeste genetiese en kongenitale afwykings in Suid-Afrika krities ontoereikend. As ‘n resultaat van die bevestigde risiko vir kommunikasie agterstand vanaf geboorte, benodig jong kinders met FAS vroëe kommunikasie intervensie (VKI). Daar blyk ‘n gaping in die navorsing aangaande die kommunikasie probleme van plaaslike jong kinders met FAS te wees. Omvattende kommunikasie profiele van jong kinders met FAS kan die behoefte aan VKI dienste beklemtoon. Die hoofdoel van die studie was om die kommunikasie profiele van ‘n groep jong kinders met FAS voor te lê. Die sub-doelwitte het die beskrywing van hulle ontwikkelings geskiedenis, gesin/sorggewer konteks, kommunikasie funksionering en die identifisering van ontwikkelings neigings in al die deelnemers behels. ‘n Saamgestelde gevallestudie is geselekteer volgens ‘n kwantitatiewe navorsings benadering. Die studie is ‘n kruisdeursnee ontwerp en beskrywende statistieke is gebruik om die deelnemers se kommunikasie vaardighede te beskryf. ‘n Doelgerigte steekproef prosedure is gebruik omdat ‘n beperkte aantal deelnemers met ‘n diagnose van FAS gevind kon word. Die vyf deelnemers wat geselekteer was vir die steekproef was gediagnoseer met FAS, woonagtig in die Gauteng area en het binne die 0 – 5 jaar ouderdomsgroep geval. Die empiriese studie het uit twee fases bestaan. Fase 1 het die ontwikkeling van die onderhoud skedule, die assesserings protokol en die uitvoering van ‘n loodsstudie ingesluit. Fase 2 het die data insameling, analise en interpretasie van resultate behels. Die resultate van die studie het aangedui dat al die deelnemers gepresenteer het met onvolledige gevalsgeskiedenisse wat van hul pleegouers verkry is en ‘n algemene ontwikkelings agterstand. Volgens die Vier-Vlak Vroëe Kommunikasie Assesserings Raamwerk het die grootste agterstande alle aspekte van kommunikasie vaardighede behels. ‘n Ontwikkelings neiging vanuit die gekombineerde kommunikasie profiele van die deelnemers het ‘n toename in agterstand met ‘n toename in kronologiese ouderdom aangedui. Die deelnemers presenteer met veelvuldige neuro-ontwikkelings behoeftes wat binne die ontwikkelings sisteem en ekologiese raamwerk beskou moet word. Gebasseer op die resultate is die diverse rolle van die spraak-taalterapeut wat met jong kinders met FAS en hulle families werk, geïdentifiseer. ‘n Raamwerk vir interdissiplinêre dienslewering aan hierdie populasie word voorgestel. Die studie het geslaag in die poging om ‘n omvattende, in-diepte beskrywing van die deelnemers se unieke kommunikasie vaardighede te verskaf. Addisioneel het die studie ook die tekort aan dienste, naamlik beperkte vroëe identifikasie en dienste toegewy aan families geaffekteer deur alkohol verwante probleme, uitgelig. Die studie is van waarde vir die spraak-taalterapeut in die kliniese en navorsings domein. Toekomstige navorsing vir die uitbreiding en ondersteuning van die studie se bevindinge word aanbeveel. / Dissertation (MCommunication Pathology)--University of Pretoria, 2011. / Speech-Language Pathology and Audiology / Unrestricted

Abstracts in English, Afrikaans and Venda / The purpose of this study was to assess the diversity of epiphytic lichens growing on Acacia karroo, A. caffra and Jacaranda mimosifolia trees in Pretoria, and to investigate the influence of air pollution, land use, altitude and climate on lichen diversity. Lichen diversity was first studied at 12 sampling sites under different land use types (high traffic areas, residential areas and industrial areas) and in protected areas (open-air museums and nature reserves). The “European guidelines for monitoring lichen diversity as an indicator of environmental stress” were then tested in 29 sites using the same tree species and under two main land use types (“Industrial areas and busy roads” and “Parks and nature reserves”). Lichen Diversity Values (LDVs) were calculated for 164 trees. Correlations of LDVs and single lichen species with environmental parameters were studied by descriptive statistics, univariate analysis, Principal Component Analysis (PCA) and Generalized Linear Models (GLM). A naturality/alteration interpretative scale based on the percentile deviation of LDVs from natural conditions was developed for the first time in South Africa. Altogether 25 taxa, predominantly foliose and subtropical to tropical species, were recorded and are reported with their ecology and distribution. An identification key was developed for easy identification of species in the field. The highest lichen diversity was found in protected areas. The LDVs of Jacaranda are lower than values for both Acacia species. “Parks and nature reserves” have significantly higher LDVs than “industrial areas and busy roads”, as demonstrated by the PCA. The GLM models were significant for LDV and some lichen species. Sampling sites in industrial areas and the proximity of busy roads are negatively related to LDV and with the frequency of many lichen species. Higher atmospheric concentrations of NOx were negatively related to LDV and to the frequency of the species Candelaria concolor, Lepraria spp. and Pyxine cocoes. Culbersonia nubila and Lepraria spp. were respectively positively and negatively correlated with atmospheric SO2. The intensity of land use appears to have a negative impact on lichen diversity. In conclusion, lichens respond well to human disturbances in Pretoria and can be used as bioindicators of naturality/alteration. The European standardised monitoring method can be applied to estimate the degree of environmental alteration in South Africa, by adopting a stratified random sampling and a more flexible strategy for tree selection. / Die doel van hierdie studie is om die diversiteit van die epifitiese ligene op Acacia Karoo, A. caffra en Jacaranda mimosifolia bome in Pretoria te bepaal, en die uitwerking van lugbesoedeling, grondgebruik, hoogte en klimaat op die ligeendiversiteit te ondersoek. Die ligeendiversiteit is by 12 monsterneemterreine bestudeer. Sommige terreine het op grond met uiteenlopende gebruike (drukverkeergebiede, woongebiede en nywerheidsgebiede) en ander in beskermende gebiede (opelugmuseums en natuurreservate) voorgekom. Die “Europese riglyne vir die monitering van ligeendiversiteit as aanduiding van omgewingstres” is telkens by dieselfde boomspesies op 29 terreine gevolg. Die hoofsoorte grondgebruik van hierdie terreine was “nywerheidsgebiede en besige paaie” en “parke en natuurreservate”. Die ligeendiversiteitswaardes (LDW’s) van 164 bome is bereken. Die korrelasies tussen LDW’s, enkelligeenspesies en omgewingsparameters is aan die hand van beskrywende statistiek, eenveranderlikeontleding, ʼn hoofkomponentanalise (HKA) en veralgemeende lineêre modelle (VLM’s) bestudeer. ʼn Verklarende naturaliteit-/wysigingskaal wat op die persentielafwyking van LDW’s in natuurlike omstandighede berus, is vir die eerste keer in Suid-Afrika ontwikkel. Altesame 25 taksa, oorwegend digblarige en subtropiese tot tropiese boomspesies, tesame met die ekologie en verspreiding van elk, is geboekstaaf. ʼn Kensleutel waarmee spesies maklik in die veld uitgeken kan word, is ontwikkel. Die grootste ligeendiversiteit het in beskermde gebiede voorgekom. Die LDW’s van Jacaranda was laer as dié van die twee Acacia-spesies. Volgens die HKA het “parke en natuurreservate” beduidend hoër LDW’s as “nywerheidsgebiede en besige paaie” gehad. Die VLM’s vir LDW en sommige ligeenspesies was veelseggend. In nywerheidsgebiede en naby besige paaie was die LDW en die voorkoms van verskeie ligeenspesies laag. ʼn Hoë konsentrasie van NOx het ʼn negatiewe verband getoon met die LDW en die voorkoms van die spesies Candelaria concolor, Lepraria spp. en Pyxine cocoes. Daarteenoor het Culbersonia nubila en Lepraria spp. onderskeidelik positief en negatief met atmosferiese SO2 gekorreleer. Die intensiteit van grondgebruik benadeel blykbaar ligeendiversiteit. Ten slotte reageer ligene goed op menslike versteurings in Pretoria. Hulle kan as bioaanwysers van naturaliteit/wysiging gebruik word. Die gestandaardiseerde Europese moniteringsmetode kan toegepas word om die mate van omgewingswysiging in Suid-Afrika te skat deur gestratifiseerde, ewekansige steekproewe te neem en ʼn buigsame strategie in boomkeuring te volg. / Ndivho ya ngudo idzi ho vha u ela ha phambano ya nzulatshinya dza epiphytic lichens dzi aluwaho kha Muunga wa Sogani, Caffra na Muṱonḓowa wa Piṱori, u sedzulusa ṱhuṱhuwedzo ya tshikafhadzo, u shumiswa ha mavu, vhunṱha na kilima kha u fhambana ha nzulatshinya.

The need for the study was prompted by discussions with my fellow photographers and friends that fewer people visited the Kruger National Park the last few years. Various reasons were given for it. I discussed it with Professors G. Puth and A. N. Schreuder, and members of the National Parks Board. Initially it was decided that a study should be done of why there was a decrease in the demand for accommodation in the Park, and how it could possibly be improved. Mr. P. Fearnhead and Professor A. N. Schreuder suggested that it would be better if a price sensitivity study should be done with a new computer program, namely conjoint analysis. This type of study has not been done in South Africa before. One of the major purposes of a conjoint analysis is to measure consumer preferences among competitive products and services. Basically it measures preferences of tourists by making trade-offs between five attributes and seventeen levels, and that consumers make complex decisions not on one factor alone but on several factors "jointly". Thus it was named conjoint analysis. Ranking a number of different combinations of attribute levels on a nine-point rating scale indicated their preferences. The results were then processed by a computer program, Conjoint Value Analysis (CVA), Version 2.0 system. They indicated their preferences by ranking a number of different combinations of attribute levels to give utility values for the attributes. Six representative camps (three large and three small ones) were used for a stratified sample of 428 respondents. The findings will give recommendations that can be used. AFRIKAANS : Die behoefte vir die studie is aangespoor deur gesprekke met my medefotograwe en vriende dat minder mense die Nasionale Kruger Wildtuin die laaste aantal jare besoek het. Veskeie redes is daarvoor gegee. Ek het dit met Professore G. Puth en A. N. Schreuder, en lede van die Nasionale Parkeraad bespreek. Oorspronklik is besluit dat 'n studie gedoen behoort te word oar hoekom daar 'n afname in die vraag vir akkommodasie in die Wildtuin was, en hoe dit moontlik verbeter kon word. Mnr. P. Fearnhead en Professor A. N. Schreuder het voorgestel dat dit beter sou wees indien 'n prysssensitiwiteit-studie met 'n nuwe rekenaarprogram, nl. gesamentlike analise ("conjoint analysis"), gedoen sou word. Hierdie tipe studie was nag nie voorheen in Suid-Afrika gedoen nie. Een van die hoof oogmerke van 'n gesamentlike analise is om verbruiksvoorkeure tussen mededingende produkte en dienste te meet. Basies meet dit voorkeure van toeriste deur kompromiee ("trade-offs") tussen vyf eienskappe en sewentien vlakke te maak, en dat verbruikers komplekse besluite maak nie oar een eienskap aileen nie, maar verskeie eienskappe gesamentlik ("jointly"). Daarom is dit gesamentlike analise ("conjoint analysis") genoem. Hulle voorkeure word gewys deur die toekenning van 'n rangorde aan 'n aantal veskillende kombinasies van eienskap-vlakke op 'n nege-punt skattingskaal. Die resultate is daarna deur 'n rekenaarprogram, Conjoint Value Analysis (CVA), Version 2.0 sisteem, verwerk. Hulle wys hulle voorkeure deur die toekenning van 'n rangorde van 'n aantal van verskillende kombinasies van eienskap-vlakke om nuttigheidswaardes vir die eienskappe te gee. Ses verteenwoordigende kampe (drie grates en drie kleintjies) is gebruik vir 'n gestratifiseerde steekproef van 428 respondente. Die bevindings sal aanbevelings gee wat gebruik kan word. / Dissertation (MCom)--University of Pretoria, 1999. / Marketing Management / MCom / Unrestricted

Various studies have highlighted the problems faced in accounting education. Some of these problems refer to the stagnating accounting curriculum, limited resources available to students from designated black empowerment groups, and the underdevelopment of skills required by practice. This study focuses specifically on the problems faced in secondary and tertiary accounting education in South Africa (SA) and the effects of these problems on practice. The first article of this study emphasises the various causes for the declining pass rate in firstyear chartered accountancy (CA) students. For this purpose, the researcher gathered information on the perceptions of first-year CA students and of lecturers involved in departments of accounting at SA universities. One of the possible causes identified is the apparent gap between school and university accounting education, especially in respect of curriculum, teaching quality and textbooks. The study revealed that students from designated black empowerment groups are facing the most problems in SA accounting education. The second article addressed the skills shortages in first-year CA trainees that practitioners have to deal with. According to the results, the majority of the participants felt that universities do not sufficiently equip students with the skills necessary to be successful in practice. The skills shortages identified included the inability of first-year trainees to determine the extent of testing needed in audits and to think independently. It also seemed as if first-year trainees lack professional communication skills and cannot sufficiently apply theory learnt at university in practice. These are only some skills with which universities are expected to equip students in order to be successful in practice. The researcher drew conclusions and made recommendations based on the information obtained from the above-mentioned two studies. / MCom (Accountancy), North-West University, Potchefstroom Campus, 2014
