The role of sustainable tourism in poverty alleviation in South Africa : a case study of the Spier tourism initiativeChifon, Godlove Ngek January 2010 (has links)
Magister Artium - MA / In South Africa, poverty engendered by the apartheid regime has long been part of the fabric of the economy. Against this background of social marginalisation, material deprivation and individual vulnerability, tourism has over the years increasingly been mooted as a strategically important and lucrative sector that, if fully explored and exploited, would lead to sustained poverty alleviation in the Republic of South Africa. The central aim of this study was to establish whether tourism as evident in the Spier Tourism model is a sustainable poverty-reduction strategy. The specific objectives of this study were to examine the socio-economic impact of Spier tourism initiatives on its workers (previously disadvantaged individuals) and the local population, to assess the pro-poor tourism practices as implemented by Spier in relation to Rogerson's pro-poor approach, to identify the challenges that Spier is facing in its pro-poor tourism approach with respect to poverty reduction goals, to provide recommendations on how the challenges can be met most effectively and to examine how pro-poor tourism can be promoted and enhanced in South Africa. The study employed both the qualitative and quantitative research designs. Data were collected through different qualitative and quantitative techniques (in-depth interviews, focus group discussions, questionnaire). Summary findings indicate that Spier has positively contributed to the socio-economic improvement in the living standards (contribution to livelihood - increased income, enhanced health and food status), through job creation, improved education/healthcare, empowerment through training and skill development, investment in the corporate social responsibility. However, Spier is still grappling with challenges such as racial disputes, insufficient income of employees and unqualified staff to mention a few. This study makes several recommendations which are based on the findings. / South Africa

Exploring attitudes of university students towards seeking psychological counsellingLawrence, Michelle January 2009 (has links)
Magister Artium (Psychology) - MA(Psych) / Student counselling services, typically located within a holistic developmental approach, aim to render comprehensive student services to service users in relation to their psychological, social, educational and spiritual well-being. However, a number of cognitive and affective barriers reportedly reduce the likelihood of young people at universities seeking professional psychological help for personal-emotional problems. Accordingly, the aim of this study, which is located within the Theory of Reasoned Action, was to explore students' attitudes towards utilising student counselling services, as well as their interpretations of the influence of age, gender and education on their attitudes and self-rated knowledge regarding seeking psychological help. The study thereby attempts to provide an understanding of the factors that influence help-seeking behaviours in university students. The research sample consisted of twenty nine students from the Cape Peninsula University of Technology. The data was collected through focus group discussions, which were conducted using an open-ended and participant centred approach to the discussion. The qualitative approach of the study was informed by the theory of social phenomenology. Data gathered from the focus group discussions was thematically analysed. The results suggest that attitudes have a potentially important influence on intentions to seek out psychological counselling. Findings show that students feel shame and guilt when they are struggling psychologically and as a result avoid seeking psychological intervention for fear of being negatively stigmatised. The study revealed that education around mental health disorders and the management thereof was crucial in order for them to be demystified and de-stigmatised, and to facilitate openness in the sharing of these problems, and society's understanding and acceptance of people experiencing psychological disorders. Results also indicate that there is a shift taking place in these attitudes, and suggest ways in which this change can be further facilitated, such as the utilisation of peer helpers who could playa key role in facilitating and reinforcing help seeking behaviour. The outcomes of the study may further contribute to informing universities' goal to provide accessible, quality and effective
development and support services to its students.

Periodontal disease in an adolescent Caucasian population in South Africa - An epidemiological surveyJosephson, Cecil Aubrey January 1983 (has links)
Magister Scientiae Dentium - MSc(Dent) / The epidemiology of periodontal disease in the Republic of South Africa has received only scant attention in the past and consequently the available information is limited. The present study was therefore planned with the primary goal being to establish base-line information regarding periodontal disease in a portion of the population. The adolescent age group was selected as the target for the survey in that
destructive periodontal disease (periodontitis) probably commences in many instances during the teenage years and therefore the group would be the one most likely to derive maximum benefit from preventive care and simple treatment measures which could be realistically provided by existing community dental health services. To translate the result into practicality a simple method of treatment needs
estimation was also incorporated. In view of the diverse nature of the inhabitants of the Republic of South Africa and in keep with previously
conducted studies, the presedt survey was confined to a single ethnic group. The population comprised all 3 .684 white pupils in Standard VIII attending the 34 schools in the Cape Peninsula during 1977. A random sample of 500 was selected for investigation. The average age of the sample was 15 years 9 months and the two sexes were equally represented. Only 7,2% were classified in the lower grade socio-economic class and thus were considered not to have a significant effect on the results. METHOD A team of three, consisting of the author and two assistants, visited each school. Portable equipment included a reclining chair, lighting, compressed air, and hand instruments. The investigation began with a questionnaire to establish the attitude to and experience of symptoms, prevention, and treatment of periodontal disease within the sample. Each subject was then examined and at each of 12 sites, on the 8 incisors and 4 first molars, recordings were made of plaque, gingivitis, supragingival calculus, subgingival calculus, and loss of attachment (periodontitis) according to defined criteria. A standard statistical package was used to analyse the recordings. RESULTS The questionnaire: This showed that almost all the subjects (98%) were interested in the prevention and treatment of periodontal disease in order to achieve and maintain oral health. Not with standing this.The overall prevalence of plaque was 97% and the mean Plaque Index (Pl.I) was 0,94 with 75% of the subjects having a mean Pl.I=0,5. The site prevalence data revealed that out of 12 sites, on average, 4 had Pl.I~O, 4 had Pl.I~l, and 4 had Pl.I~2. In the maxilla the molar sites had the
higher plaque levels, whilst in the mandible the incisor sites had higher plaque levels. The sex-specific data showed the males to have higher mean plaque levels than the females, but in 50% of sample with a mean PI.I 0,5 to 1,45 there was ) had had any appurtenant treatment. The overall prevalence of plaque was 97% and the mean Plaque Index (Pl.I) was 0,94 with 75% of the subjects having a mean Pl.I=0,5. The site prevalence data revealed that out of 12 sites, on average, 4 had Pl.I~O, 4 had Pl.I~l, nd 4 had Pl.I~2. In the maxilla the molar sites had the
higher plaque levels, whilst in the mandible the incisor sites had higher plaque levels. The sex-specific data showed the males to have higher mean plaque levels than the females, but in 50% of sample with a mean PI.I 0,5 to 1,45 there was no difference.

Die doeltreffendheid as kariesvoorkomingsmaatreel van in 0,2% en in 0,05% neutrale natriumfluoried-mondspoelmiddelvan Wyk, Irma January 1985 (has links)
Magister Chirurgiae Dentium (MChD) / The study was carried out to 1) determine the effectiveness of the caries inhibiting effect of a weekly mouthrinsing programme in South African schools over a three year period and 2) compare neutral solutions of 0,2 per cent and 0,05 per cent NaF using a placebo of tapwater as control. Twelve to 13 year old White school children from eight randomly selected schools in the Parow School Board area of the Cape Peninsula were chosen. Participants were randomly assigned to one of the three rinsing groups. After three year's participation, the mean net increment in DFS per child was 4,7 for the 0,2 per cent NaF group; 5,9 for the 0,05 per cent NaF group and 7,5 for the placebo. These differences are statistically significant (p<:O,OOI). This meant a caries reduction of 38 per cent for the stronger and 21 per cent for the weaker sodium fluoride mouth rinse. It is concluded that such a mouth rinsing programme is a practical, feasible and an efficient approach
to caries prevention in South African circumstances.

Exploring the potential of digital storytelling in the teaching of academic writing at a higher education institution in the Western CapeMkaza, Linda Olive January 2019 (has links)
Doctor Educationis / Writing is an important skill throughout learners’ schooling trajectory because it is through writing that learners need to situate meaning and sense-making across the curriculum. Writing proficiency becomes even more important when learners access tertiary studies. Yet studies suggest that most students struggle with academic writing. Various authors suggest that writing has not been taught appropriately especially in secondary schooling contexts in South Africa and that writing becomes even more daunting for Second Language speakers of English when they reach tertiary education. There is abundant literature on students’ challenges with academic writing and ways to address academic writing challenges but the use of digital storytelling in relation to academic writing development is recent and distinctively underexplored in the literature.

An empirical study of the development of factory shops in the clothing industry in the Cape PeninsulaVisser, D.J. January 1991 (has links)
Magister Commercii - MCom / Over the 1ast eight years up to 1989, a new business phenomenon has manifested itself in South Africa. During this period, the so-ca 11ed "factory shop" concept has developed into one of the fastest growing industries in both the manufacturing and commercial sectors. In South Africa, factory shops have initially established in the Cape Peninsula.4,5. The nature of these shops is such that their creation may be attributed to the clothing industry itself ;" This trend originated in about 1980 at a few clothing manufacturers in Cape Town, inter alia, Desiree, Readywear, Atlantic Knitting Mills. Originally these factory shops were open for limited hours, I usually over lunch-time and on only one Saturday per month. They were strictly limited to and for the sole benefit of I the staff of those firms. Gradually, however, family and
later friends and acquaintances of these staff members became aware of the so-called bargain prices at these stores. Both supply and demand played important roles in the development of factory shops. For example, increasing pressure on management to supply larger quantities of these merchandise items at bargain prices, as well as the fact that clothing factories had excess stock which was difficult
to clear through the normal distribution channels. Factory owners recognized and seized this opportunity to reduce stock at little additional cost. From their inception, factory shops have had a significant influence on the turnover and profitability of the retail clothing industry. This trend is documented in reports by the organ i zed trade, 7 ,B where reference has been made to the influence of these factory shops and where independent clothing retailers have been calling for a plan of action for protect i on against the encroachment by these factory
shops on their (the clothing retailers') markets. However, up to that stage, no in-depth study or formal research was done to justify such action for protection. The ref 0reitwa s felt that" An empirical stud y of the development of factory shops in the clothing industry in
the Cape Peninsula" was needed to acquire an objective view of the state of affairs.

Biting the hand that feeds you: Visitor perceptions of visitor-baboon interaction in the Cape PeninsulaSefela, Farren January 2020 (has links)
Masters of Art / The rapid increase in urbanisation and tourism in the Cape Peninsula has increased the rate of human-wildlife interaction. The Cape Peninsula is unique in terms of placing urban areas next to protected natural areas with no physical barriers, thus allowing animals, especially baboons, to travel between the two areas, occasionally leading to conflict between humans and wildlife. Visitors to popular tourist sites may also actively participate in feeding baboons or through negligence by leaving food items in the open. As a result, changing the habits of the baboons as human food and food waste are seen as the preferred option in terms of dietary habits. The main aim of this study was to investigate the perceptions and social construction of visitors in the Cape Peninsula towards baboons at tourist sites. Social constructionist theory was used as the theoretical framework for the study, which looks at the way people perceive nature and wildlife, which is unique to each person. The study uses an exploratory sequential mixed methods design, with a qualitative section that includes three semi-structured interviews, followed by a quantitative section consisting of a questionnaire survey, with 201 questionnaires being completed. The survey was conducted at key tourist sites around the Cape Peninsula that are well known for baboon sightings, including Bordjiesrif Picnic Site, Buffels Bay viewpoint, Cape of Good Hope/Cape Point and Dias Beach. The study used discourse analyses and the Statistical Package for the Social Sciences (SPSS) to analyse the data, which allowed for ideas to be labelled and linked to opinions in the literature, and patterns identified during the data collection. Visitors viewed tourism spaces as anthropocentric areas, and thus perceived baboon-visitor interactions through conditional acceptance. Visitor perceptions and social construction of baboon-visitor interactions may be positive when conditional acceptance is adhered to, and negative when conditional acceptance is broken. Recommendations for further research includes more research on non-consumptive tourism activities and its impact on human-wildlife interactions, with a need for more literature on the influence of education on people’s attitudes towards wildlife, and finally, more research that focuses on the changing behavioural ecology of baboons, due to an increase in tourism/visitation.

Rheological model influence on pipe flow predictions for homogeneous non-Newtonian fluidsVan Den Heever, Emile January 2013 (has links)
Dissertation submitted in fulfilment of the requirements for the degreerequirements Master of Technology: Civi Engineering in the Faculty of Engineering
at the Cape Peninsula University of Technology
Supervisor: APN. Sutherland
Co-supervisor: Prof. R. Haldenwang
Cape Town
October 2013 / The reliable prediction of pressure drop versus flow rate for non-Newtonian pipe flow is important in many industrial processes. In laminar flow scale up is straightforward, but transitional velocity and turbulent flow predictions remain a practical problem. Various theoretical models exist, but nothing in literature shows conclusively which of these is the most reliable and consistent, nor is it evident what effect the choice of rheological model has on the predictions. The aim of this work was to i) evaluate the influence of different rheological models when used in existing prediction techniques for non-Newtonian flow ii) characterise each material type using selected (commonly used) rheological models and iii) predict laminar, transitional and turbulent pipe flow characteristics for each material type using existing prediction techniques, for comparison with experimental results.
Only time-independent, homogeneous, non-Newtonian fluids in pipe sizes from 13mm to 200mm were investigated. Rheological models and laminar flow predictions used only the power law, Bingham plastic, Herschel-Bulkley, Casson and Hallbom yield plastic models. The techniques used to predict transitional velocity were Ryan & Johnson, Metzner-Reed, Hedström intersection method, Slatter and Hallbom. For turbulent flow the Newtonian approximation, Dodge & Metzner, Wilson & Thomas, Slatter, Hallbom modified Wilson & Thomas and the Bowen correlation methods were used. The study documents the relevant theory and presents an assessment of the influence of rheology on pipe flow predictions, summarised in terms of the practical performance of the various rheological model/prediction method combinations for the different materials.
In laminar flow at practical pseudo shear rates (8V/D; taken as 40s-1) the choice of rheological model does not significantly influence pressure drop predictions. For yield-pseudoplastic materials (eg. kaolin) the Hedström intersection and the Slatter Reynolds number method with Bingham plastic or Casson rheology predicted transitional velocity most accurately. For Bingham plastic materials (eg. bentonite) the best predictions were obtained using the Metzner & Reed Reynolds number with Bingham plastic rheology, although similar results were observed for this technique with all rheologies. The transitional velocity for pseudoplastic materials (eg. CMC) was best predicted by the Slatter and Metzner & Reed Reynolds number methods, using power law or Casson rheology.
For turbulent flow of yield pseudoplastic materials the Slatter method using the Casson rheology gave the most accurate predictions overall. Turbulent flow of Bingham plastic materials was best predicted by the Slatter, Hallbom pseudo fluid Nikuradse and Dodge & Metzner methods, using Bingham plastic, Casson or yield plastic rheology. For pseudoplastic materials the Slatter and Wilson & Thomas methods were the most accurate, when used with yield plastic or power law rheology. Transitionalal velocity and turbulent flow predictions for materials with a yield stress vary significantly with rheological model. Laminar data should therefore be examined thoroughly and rheological models fitted with care. For pseudoplastic fluids there is little difference in predictions between the various techniques as long as power law rheology is used.

Development of a multi-cell inverter topology for driving nonlinear piezoelectric loadPentz, Rory Adriaan January 2014 (has links)
Thesis submitted in fulfilment of the requirements for the degree
Magister Technologiae Electrical Engineering
in the Faculty of Engineering
at the Cape Peninsula University of Technology
Supervisor: Mr. J. Wheeler
Co-supervisor: Dr. R.H. Wilkinson
Cape Town
October 2013 / This report presents the design and development of a five cell multicell inverter for driving a piezoelectric load. The multicell inverter was chosen for this application as it became evident that it would be more suitable for driving piezoelectric transducers due to its high apparent switching frequency. The multicell inverter was designed using DirectFET’s as this type of FET has a high current switching ability in a very small package. A positive and negative bootstrap power supply was incorporated in the design to reduce the number of supplies to power the gate drive circuits of the multicell inverter.
Three compensation networks were designed and constructed to investigate which one would transfer the most energy to the piezoelectric transducer. It was also important to investigate whether these compensation networks were able to reduce the harmonic content produced by the multicell inverter. This is necessary in order to excite the transducer correctly. It was found that the Q-Matching compensation network reduced the harmonic content applied to the load the most. Experiments were also conducted to determine if the advantage of the apparent frequency of the multicell inverter would mean that the piezoelectric load could be driven directly with the multicell inverter without any damage to the transducer. It was however required to increase the applied apparent power to the transducer to compensate for the reactive component of the load in order to melt the plastic which was used as the load to the transducer.
Experiments were conducted to determine if the charge on the cell capacitors of the multicell inverter would stay balanced while driving a non linear load such as a piezoelectric transducer. The results showed that the voltages stayed balanced when driving the piezoelectric transducer.
