2015-12-31 Effective public leadership to drive organisational change in the public health sector in order to improve service delivery : the case of the Western Cape Department of HealthIsaacs, Rafeeqah 04 1900 (has links)
Thesis (MPA)--Stellenbosch University, 2015. / ENGLISH ABSTRACT: The goal of this research was to investigate effective leadership that drives organisational
change in the public health sector to meet the changing environmental needs to improve
service delivery within the Western Cape Department of Health. Organisational change in the
public health sector must lead to improved public health service delivery.
The role of leadership is to deal with incompetent personnel as they are the cause of problems
regarding inadequate service delivery. Leadership must contribute to the main areas where
competency development needs to take place. Healthcare 2030 requires transformational
leadership from the ranks of managers and clinicians for collective and distributed leadership
across all levels of organisations.
The research methodology used in this study was a combination of qualitative and
quantitative research methodologies. The methodology included an empirical investigation in
the form of a literature review and a preliminary semi-structured interview as well as a nonempirical
investigation. The empirical investigation was conducted by using semi-structured
interviews as well as a survey questionnaire which was designed to gather information
focussing on leader personality traits, task-related traits and understanding the organisation.
This study specifically focussed on effective public leadership to drive organisational change
in the health sector and to improve service delivery. The results provide support for a
cohesive trait-behavioural model of leadership effectiveness. In general, leadership traits
associated with task competence are related to task-oriented leadership behaviours, which
improve performance-related leadership outcomes. Effective leadership in the public health
sector that drives organisational change is based on the general personality traits of a leader,
task-related traits and understanding the organisation. These are the elements that are
important for effective public leadership to improve service delivery. / AFRIKAANSE OPSOMMING: Die doel van hierdie navorsing was om doeltreffende leierskap, wat organisatoriese
verandering in die openbare gesondheidsektor teweeg kan bring, te ondersoek. Sodoende kan
in die veranderende omgewingsbehoeftes voorsien word en kan die Wes-Kaapse Department
van Gesondheid verbeter. Organisatoriese verandering in die openbare gesondheidsektor
moet tot verbeterde openbare gesondheidsdienslewering lei.
Die rol van leierskap is om onbekwame personeel te hanteer omdat hulle die oorsaak van
probleme met betrekking tot onvoldoende dienslewering is. Leierskap speel ‘n sleutelrol in
die bevordering van bevoegdheidsontwikkeling. Healthcare 2030 vereis transformerende
leierskap uit die geledere van bestuurders en dokters oor alle vlakke van organisasies heen.
Die navorsingsmetodologie wat in hierdie studie gebruik is, was ’n kombinasie van
kwalitatiewe en kwantitatiewe navorsingsmetodologieë. Die metodologie het ’n empiriese
ondersoek in die vorm van ’n literatuuroorsig en ’n voorafgaande semi-gestruktureerde
onderhoud asook ’n nie-empiriese ondersoek, ingesluit. Die empiriese ondersoek is uitgevoer
deur van semi-gestruktureerde onderhoude en ’n opnamevraelys gebruik te maak. Die vraelys
is ontwerp om inligting met betrekking tot leiers se persoonlikheidseienskappe, taakverwante
eienskappe en ’n begrip van die organisasie te ondersoek.
Hierdie studie het spesifiek op doeltreffende openbare leierskap gefokus om organisatoriese
verandering in die gesondheidsektor te bewerkstellig en dienslewering te verbeter. Die
resultate ondersteun ’n samehangende eienskapgedragmodel van leierskapdoeltreffendheid.
Oor die algemeen is leierskapeienskappe wat met taakbevoegdheid geassosieer word,
verwant aan taakgeöriënteerde leierskapgedrag wat prestasieverwante leierskapuitkomste
verbeter. Doeltreffende leierskap in die openbare gesondheidsektor wat organisatoriese
verandering dryf, is gegrond op die algemene persoonlikheidseienskappe van ’n leier, taakverwante
eienskappe en ’n begrip van die organisasie. Dit is die elemente wat belangrik is vir
doeltreffende openbare leierskap om dienslewering te verbeter.

Addressing diminishing profit margins within the Dutoit Group : a value chain analysisDu Plessis, J. S. 12 1900 (has links)
Thesis (MBA)--Stellenbosch University, 2014. / ENGLISH ABSTRACT: Rapid urbanisation, coupled with growing per capita incomes and a rapid rising middle class, is triggering rapid growth in urban food markets. Despite these opportunities, agriculture in South Africa is confronted with diminishing profit margins due to direct production cost increasing at rates above the revenue generated from agricultural products. This research assignment has aimed to define the attributes of an effective agricultural value chain in South Africa, given the challenges faced. To achieve this goal, the research focus was on the results of an in-depth analysis of the Dutoit Group’s deciduous fruit value chain.
To be able to perform a value chain analysis it is of utmost importance to first understand the meaning of the concepts as well as their origin and the evolution of their application. This is achieved through a comprehensive study of literature. Three value chain analysis tools were used for the research. These tools were an industry analysis, value chain maps and benchmarking. Through the literature review the importance and relevance of these three tools were also explored and reasons provided why they can be regarded to be adequate for a proper in-depth analysis.
An overview of the Dutoit Group’s history, focusing on the specific key events influencing the evolution of their value chains, is also discussed together with their business philosophy, business model and main accomplishments. This is done to provide context to the environment in which the value chain analysis process was performed.
The main focus of the fourth chapter is the application of the three value chain analysis tools on the Dutoit Group’s deciduous fruit value chain, utilising primary and secondary data collected through interviews with specific value chain actors, observations, management information and literature obtained from the public domain. Through the application of the three value chain analysis tools the effectiveness of the Dutoit Group’s deciduous fruit value chain was evaluated, and strengths and weaknesses identified.
The research results showed that the Dutoit Group’s internal deciduous fruit value chain has been effective in addressing the risk of diminishing profit margins. In addition the results showed that the key attributes of an effective value chain which are able to address the current challenges are defined as effective integration, strong relationships between value chain actors, high levels of productivity and strong leadership.

Successful integration of upcoming farmers in the commercial farming sector : a focus on the Western CapeNel, Jacobus E. 04 1900 (has links)
Thesis (MBA)--Stellenbosch University, 2015. / ENGLISH ABSTRACT: In South Africa, land reform and the development of upcoming farmers are part of the country’s transformation objectives. The development of upcoming farmers into commercial farmers therefore requires the growth of sustainable agri-businesses. Unfortunately, limited success has been achieved in terms of land reform and the country is far from its set targets.
This study examined the factors that gave current successful, upcoming commercial farmers the advantage to grow their businesses up to a certain level. Data was collected through interviews with farmers, mentors, transformation managers and governing bodies such as Agri-West Cape. Interviews on the farms gave the researcher the opportunity to observe underlying factors that can influence their businesses. The objective of the study was to determine the critical success factors that relate to the success of upcoming commercial farmers in the Western Cape.
The results identified a number of success factors, some of which were unexpected and in contrast with some of the literature sources.
All the cases covered in this study – i.e. successful, upcoming commercial farmers in the Western Cape – used different business models and emphasised the importance of proper management. They also used their detailed business plans as a handbook for successful farming, and acknowledged the important role of mentors. Only a mentor-farmer relationship based on trust and respect worked in the end. The mentors took on coaching roles that were not limited to farming activities but included an equally important people development component. A sustainable market was identified as one of the critical success factors for successful upcoming commercial farmers.
One of the biggest hurdles for upcoming farmers was financial management. Hence, they required dedicated financial management to be sustainable.
One of the main outcomes of the study was the importance of the personal profile of the farmers and their understanding of the opportunity. Focusing on short-term financial gains resulted in failure. All the farmers in the case studies displayed a deep understanding of the long-term goal of their businesses and their role in that.
Transformation, land reform and building an equal society in South Africa are burning points for the nation. The success of upcoming farmers helps to build confidence that the hard work is paying off.

Old field restoration : vegetation response to soil changes and restoration efforts in Western Cape LowlandsMemiaghe, Herve Roland 12 1900 (has links)
Thesis (MScConsEcol (Conservation Ecology and Entomology))--Stellenbosch University, 2008. / In the Mediterranean climate regions of the world, agricultural practices have caused
considerable landscape transformation and lead to introduction of alien species that now
dominate secondary succession on abandoned agricultural fields. Various restoration attempts
have been made to reduce alien plant species cover, and to enhance the re-establishment and
cover of native plant species. However, results and successes were mostly short-term due to
re-growth and persistence of the weedy alien species, which has been suggested to be caused
by land use history, especially the nutrient enrichment of soil, and particularly phosphorus
and nitrogen.
This study investigated different soil properties (pH, electrical conductivity (EC), soil
moisture, as well as available phosphorus (P) and total nitrogen (N)) on 10 and 20 year old
abandoned fields, as a function of depth in three habitats (ridge (old cultivated area), ditch
(old drainage line) and slope (intermediate zone between ridge and ditch)) on the old fields.
The relationship between these soil properties and the vegetation occurring on the two old
fields was established. At the same time, restoration treatments (autumn burn, combination of
autumn burn and herbicide, herbicide application alone, as well as spring burn) were
conducted to reduce the cover and abundance of non-native plant species and Cynodon
dactylon, and to enhance cover of native species.
Results from the study show that levels of all investigated soil properties were higher on the
younger field. The highest difference was observed in EC and pH. Seasonal differences in
both soil properties could also be observed. A principal component analysis indicated that the
dynamic of all soil properties shaped the vegetation type on old fields, with the main soil
properties being dependent on land-use history and time since abandonment. This study
suggests that EC and pH could be part of parameters that drive the persistence of undesirable
species persistence on old fields and inhibit native plant species instead.

Vegetation patterns and dynamics of Renosterveld at Agter-Groeneberg Conservancy, Western Cape, South AfricaWalton, Benjamin Alan 03 1900 (has links)
Thesis (MSc (Conservation Ecology and Entomology)--University of Stellenbosch, 2006. / Swartland Shale Renosterveld is restricted to fertile fine-grained soils in the winter rainfall region of
the Western Cape. Between 91% and 97% of this vegetation type is transformed, mostly due to
agriculture. Remaining fragments have an irreplaceable conservation value due to a high richness of
endemic geophytes. Information on renosterveld vegetation composition and response to
disturbance is sparse. Research occurred at three sites near Wellington: Voëlvlei Provincial Nature
Reserve (CapeNature), Elandsberg Private Nature Reserve (Elandsberg Farms (Pty.) Ltd.), and
Krantzkop munitions factory (Armscor/Somchem) forming a contiguous fragment in the Agter-
Groeneberg Conservancy. The primary research aim was to identify or ascertain patterns of plant
succession in Swartland Shale Renosterveld and associated different-aged old fields (previously
ploughed), with the interaction of grazing. The key research questions are: (1) What are the plant
communities of unploughed renosterveld and different-aged old fields which originated in habitats
of ploughed renosterveld? (2) What are the most characteristic features of the floristic and
ecological relationship between the described plant communities in terms of ecological factors
operating within the studied system? (3) Does total species and life-form group richness differ
between natural vegetation and old fields? (4) Is life-form richness influenced by ploughing and
grazing or the interaction between these disturbances? (5) Is life-form cover-abundance influenced
by ploughing and grazing or the interaction between these disturbances? (6) Does alien plant
species richness differ amongst seres, and with different levels of grazing intensity? A comparison
of life-form richness and cover-abundance of old field vegetation was made with adjacent natural
unploughed “controls”. The effects of ploughing on community structure, with the inclusion of
grazing was established. These life-form richness comparisons also occur across a gradient of
increasing large mammalian herbivore grazing intensity. Sampling was conducted in winter and
spring using nested 1000m2 relevés.
A hierarchical classification, description and floristic interpretation of renosterveld and old field
vegetation were made using TWINSPAN, SYN-TAX 2000 and CANOCO. The samples were
classified with TWINSPAN and two communities were described at the association level, namely:
Ursinia anthemoides–Cynodon dactylon Grassland Community (with two variants) and the
Pterygodio catholici–Elytropappetum rhinocerotis Shrubland Community (with two subassociations),
respectively. The vegetation data were further hierachically classified using SYNTAX
2000 which revealed similar clustering of sample objects to that resulting from classification and ordination. Following ordination of sample objects with CANOCO, select groups of species
were used to depict their response curves in relation to seral development.
Briefly it was found that the effects of grazing vs. non-grazing was more pronounced on old fields
than in unploughed vegetation. Overall total species and life-form richness was reduced by
ploughing with old fields requiring a recovery period of 30 years to resemble unploughed
vegetation.
Keywords: Swartland Shale Renosterveld, phytosociology, vegetation patterns, life-forms,
succession, disturbance, ploughing, grazing, old fields.

Die gebruik van 'n swaainet vir die monitering en diversiteitsbepaling van insekte op lusern in die Wes-KaapDe Villiers, M. (Marelize) 03 1900 (has links)
Thesis (MScAgric)--University of Stellenbosch, 2002. / ENGLISH ABSTRACT: Lucerne is the most important pasture and fodder crop in the winter rainfall area of
South Africa. Various pests are known to cause damage to this crop. The use of the
sweep net for monitoring pests is a cheap, easy and quick technique. If the sweep net
is suitable for the lucerne pests in South Africa, potential pest status can be
determined easily and quickly and the necessary precautionary measures taken to
prevent crop losses. From a managerial point of view, it is also important to know
the composition of the insect community in order to follow practices in which the
number of beneficial insects can be increased and the injurious insects decreased.
Therefore a study was done to quantify the use of the sweep net as a survey
technique for monitoring pests on established lucerne stands. Insect diversity was
also determined to obtain information on the insect families and guilds on lucerne.
The redlegged earth mite, due to its importance as a pest, and the Anystis mite,
important as a predator, were also included.
The sweep net proved to be suitable for the sampling of the main lucerne pests. If a
29 cm diameter sweep net is swiped once per pace for six long paces, twelve
systematically chosen sampling units are recommended for the lucerne earth flea and
aphids. It is not necessary to differentiate amongst the three aphid species, or
between the winged and unwinged aphids. Actual counts should be used instead of
absence-presence data. Instead of counting all the insects in a sample, sub-samples
can be taken. Operational characteristic curves can be used to determine the risk
involved in the decision not to intervene, for example by spraying or grazing.
Recommendations for monitoring and the accuracy of control decisions for the
redlegged earth mite, Sitona weevil and lucerne butterfly can only be made after
threshold values have been determined.
The pea aphid, bluegreen aphid and lucerne earth flea showed peaks in their
population levels during spring. Peak numbers of the spotted alfalfa aphid occurred
during late summer and autumn. The Sitona weevil and lucerne butterfly numbers
reached peak levels during late spring and early summer. For all pests population levels were dramatically reduced after grazing or cutting of the plantings. Therefore,
these cultivation practices provided good control.
The herbivores made up more than 85% of the insect community in lucerne. The
largest herbivorous families, in terms of the number of individuals per family, were
the Aphididae and Sminthuridae. These two families contain the main lucerne pests,
the pea aphid, bluegreen aphid, spotted alfalfa aphid and the lucerne earth flea. The
largest predatory family was the Anystidae, represented by the Anystis mite, the
most important predator of the red legged earth mite and lucerne earth flea. Another
well represented predatory family was the Coccinellidae, containing natural enemies
of the aphids. The dryland plantings had a higher percentage of predators than the
irrigated lucerne.
The most important parasitaids were those in the superfamily Chalcidoidea and in
the family Braconidae. The main detritivores were springtails in the suborder
Arthropleona, insects in the families Mycetophilidae on irrigated lucerne, and
Mycetophagidae on dryland lucerne. The most abundant visitors were in the families
Chironomidae, Drosophilidae and Tephritidae. The dryland plantings had a lower
percentage of visitors than the irrigated plantings.
The number of insect families, as well as the number of individuals per family, was
lower at the dryland plantings than at the irrigated plantings. The vast majority of
insect families found on lucerne were collected during the one-year sampling period.
A lower diversity was found where grazing was more severe, and there was a
negative relationship between diversity and evenness. / AFRIKAANSE OPSOMMING: Lusern is die belangrikste wei- en voergewas 10 die winterreëngebied van Suid-
Afrika. Hierdie gewas word deur 'n verskeidenheid plae aangeval. Die gebruik van
die swaainet vir die monitering van plae is 'n goedkoop, maklike en vinnige tegniek.
lndien die swaainet geskik is vir die betrokke plae in Suid-Afrika, kan potensiële
plaagstatus van die plae dus maklik en vinnig bepaal word en die nodige
voorsorgmaatreëls getref word om verliese te voorkom. Vanuit 'n bestuursoogpunt
is dit ook belangrik om te weet wat die samestelling van die insekgemeenskap is
sodat praktyke gevolg kan word waardeur die getal voordelige insekte verhoog en
nadelige insekte verlaag word. Gevolglik is 'n studie uitgevoer om die gebruik van
die swaainet te kwantifiseer as 'n monsternemingsmetode vir die monitering van plae
op gevestigde lusernstande. Insekdiversiteit is ook bepaal ten einde inligting te
bekom oor die insekfamilies en -gildes op lusern. Die lusernerdvlooi en
swartsandmyt, vanweë hul belang as plae, en die Anystis-roofmyt, vanweë sy belang
as predator, is ook ingesluit.
Die swaainet blyk geskik te wees vir die monitering van die. vernaamste lusernplae.
Wanneer 'n 29 cm deursnee swaainet vir ses lang treë een keer per tree geswaai
word, word 12 sistematies gekose steekproefnemingseenhede vir die lusernerdvlooi
en plantluise aanbeveel. Daar hoef nie onderskeid tussen die plantluisspesies en
tussen gevleuelde en ongevleuelde plantluise getref te word nie. Daar moet gebruik
gemaak word van werklike insektellings en nie van aanwesigheid-afwesigheid data
nie. In plaas van om al die insekte in 'n monster te tel, kan submonsters geneem
word. Operasionele karakteristieke kurwes kan gebruik word om die risiko verbonde
aan die besluit om nie op te tree, deur byvoorbeeld te spuit of bewei nie, te bepaal.
Vir die swartsandmyt, Sitona-snuitkewer en lusernskoenlapper moet drempelwaardes
eers vasgestel word voordat aanbevelings vir monitering en die akkuraatheid van
besluite rakende beheer, gegee kan word.
Vir die ertjieluis, blougroenluis en lusernerdvlooi het die bevolkingsvlakke 'n piek in
die lente bereik. Die gevlekte lusernluis se piekgetalle was hoofsaaklik in die laat
somer en herfs. Die Sitona-snuitkewer en lusernskoenlapper het piekgetalle gehad in die laat lente en vroeë somer. Vir al die plae het bevolkingspieke drasties afgeneem
nadat die aanplantings bewei of gesny is. Hierdie verbouingspraktyke blyk dus goeie
beheer te verskaf.
Die herbivore op lusern het meer as 85% van die insekgemeenskap beslaan. Die
grootste herbivoorfamilies, in terme van aantal individue per familie, was die
Aphididae en Sminthuridae. Hierdie twee families bevat die vernaamste lusernplae,
naamlik die ertjieluis, blougroenluis, gevlekte lusernluis en lusernerdvlooi. Die
grootste predatoriese familie was die Anystidae, wat verteenwoordig is deur die
Anystis-roofmyt. 'n belangrike predator van die swartsandmyt en lusernerdvlooi.
Nog 'n predatoriese familie wat goed verteenwoordig was, was die Coccinellidae,
natuurlike vyande van plantluise. Die droëland aanplantings het 'n hoër persentasie
predatore gehad as die besproeide lusern.
Die belangrikste parasitoïede aanwesig was dié in die superfamilie Chalcidoidea en
familie Braconidae. Die vernaamste detritivore was erdvlooie in die suborde
Arthropleona, insekte in die families Mycetophilidae by besproeide lusern, en
Mycetophagidae by droëland lusern. Die volopste besoekers was lede van die
families Chironomidae, Drosophilidae en Tephritidae. Die droëland aanplantings het
'n laer persentasie besoekers gehad as die besproeide lusern.
Die aantal insekfamilies, asook die aantal individue per familie, was laer by die
droëland aanplantings as by die besproeide aanplantings. Die oorgrote meerderheid
insekfamilies wat op lusern voorkom, is gedurende die een jaar opnameperiode
waargeneem. 'n Laer insekdiversiteit is gevind waar beweiding strawwer was, en
daar was 'n negatiewe verband tussen diversiteit en gelykmatigheid.

An investigation into the factors influencing the health status of the coloured people of the Western Cape in an urban settingStellenberg, Ethelwynn L. (Ethelwynn Linda) 12 1900 (has links)
Thesis (DCur)--Stellenbosch, 2000. / ENGLISH ABSTRACT: Guided by the researcher's clinical experience and through recent outreach
research projects (Stellenberg, 1996 and 1997) the factors influencing the health
status of two communities were identified through health screening. It was
further identified that these problems affecting the health status of these
communities were magnified through the poor accessibility, availability, and
affordability of health services.
According to the researcher, despite the efforts of the Government and attempts
to remedy the disparities of the past, the introduction of any such policy should
be based on scientific evidence.
The researcher decided to investigate the factors influencing the health status of
the Coloured people of the Western Cape. This population group is the largest
in the Western Cape, being 60,8%. Its domination in this province determines
the health status of the province. By acquiring knowledge about the factors
influencing the health status of the Coloured population, it will be possible for the
policy makers in health care to direct their emphasis on health care policies more
appropriately. Currently differences in socio-economic and knowledge levels,
along with existing inequalities in health service pose major challenges for the
policy makers in health care. Therefore, knowledge about the health status,
health practices and health beliefs of minority groups will improve the average
health status of the general population.
It is against this background, that this research study was undertaken. Specific
objectives were set for the study.
• To determine the health status of economically active Coloured people in
an urban area as defined with specific reference to the indicators as
identified by the researcher
• To determine the prevalence of factors influencing the health status of
economically active Coloured people in an urban area as defined.
• To determine the relationship between the health status and the factors
influencing the health status of economically active Coloured people in an
urban area as defined.
• To determine an association between factors influencing the health status of economically active Coloured people in an urban area as defined.
• To make recommendations to the health policy-makers concerning factors
influencing the health status of the economically active Coloured people in
an urban area as defined and possibly related ethnic groups.
These objectives were met through an in-depth research study of this population
group in six identified suburbs. Factors influencing the health status of an
individual as described in the literature were explored and described. The
recommendations based on the findings confirmed that the health status of the
Coloured population is influenced by the following factors:
• Socio-economic Level (education, financial income and occupation)
• Lifestyle of individuals (High Risk Behavioural Practice such as smoking,
use of alcohol and illegal drugs, dietary intake, minimal exercise, stress
management and leisure time)
• Ethno-cultural Beliefs: health and illness
• Religion, health and illness
• Environmental factors
• Health Services: accessibility and affordability of services
Recommendations based on the findings
• Emphasis on re-development and health education of all age groups.
• The introduction of social grants for those who are unable to support
themselves and their families have become essential in order to improve
their health status.
• The creation of jobs to improve the socio-economic circumstances of the
populations.
• Current health services at primary health care level and environmental
factors influencing the health status of the population require urgent
attention. / AFRIKAANSE OPSOMMING: Gelei deur die navorser se persoonlike kliniese onde'rvinding asook onlangse
navorsingsprojekte oor uitreikingsaksies ten opsigte van gemeenskapsgesondheid
(Stellenberg, 1996 en 1997), is faktore wat In rol in die
gesondheidstatus van gemeenskappe speel, geïdentifiseer. Daar is ook bevind
dat faktore wat probleme rondom die gesondheidstatus van hierdie
gemeenskappe vererger, elemente is soos toeganklikheid, beskikbaarheid en
bekostigbaarheid van gesondheidsdienste.
Ten spyte van pogings van die regering om die ongelykhede van die verlede uit
die weg te ruim behoort die regstelling daarvan volgens die navorser op
wetenskaplike bewyse gegrond te word.
Die navorser het daarom besluit om die faktore wat gesondheidsorg van die
Kleurlinggemeenskap in die Wes-Kaap beïnvloed, te ondersoek. Hierdie
bevolkingsgroep is die grootste in die Wes-Kaap, naamlik 60,8%. Die
oorheersing van die Kleurling in die provinsie bepaal grootliks die
gesondheidstatus van die provinsie. Deur kennis in te win van faktore wat die
gesondheidstatus van die Kleurlinggemeenskap beïnvloed, is dit moontlik vir
besluitnemers in gesondheidsorg om dit beter te bestuur. Daarom sal kennis oor
gesondheidsorg, gesondheidspraktyke en -gelowe van minderheidsgroepe die
gesondheidstatus van die totale bevolking verbeter.
Dit is teen hierdie agtergrond wat die navorsing onderneem is. Spesifieke
doelwitte vir die studie was om die volgende te bepaal:
• Die gesondheidstatus van die ekonomies aktiewe Kleurling-gemeenskap
in In stedelike gebied soos gedefinieer met spesifieke verwysing na die
indikatore soos geïdentifiseer deur die navorser
• Die prevalensie van faktore wat 'n invloed op die gesondheidstatus van
die ekonomies aktiewe Kleurling-gemeenskap in In stedelike gebied soos
gedefinieer
• Die verwantskap tussen die gesondheidstatus en die faktore wat In
invloed uitoefen op die gesondheidstatus van die ekonomies aktiewe
Kleurling-gemeenskap in In stedelike gebied soos gedefinieer
• Die moontlike assosiasie te bepaal tussen faktore wat die gesondheidstatus beïnvloed van die ekonomies aktiewe Kleurlinggemeenskap
in In stedelike gebied soos gedefinieer.
• Aanbevelings aan die gesondheidsowerheidsbeleidmakers oor bevindings
wat In invloed uitoefen op die gesondheidstatus van die ekonomies
aktiewe Kleurling-gemeenskap in In stedelike gebied soos gedefinieer, en
moontlike verwant etniese groepe.
Die doel is bereik deur in-diepte navorsingsonderhoud met die Kleurling
bevolkingsgroep in ses geïdentifiseerde gebiede. Faktore wat die
gesondheidstatus van individue soos in die literatuur beskryf beïnvloed, is
ondersoek en beskryf. Die aanbevelings is gebasseer op bevindings gedoen in
die ondersoek van die gesondheidstatus van die Kleurling bevolking, en is deur
die volgende faktore in die ondersoekgroep beïnvloed:
• Die sosio-ekonomiese vlak (opleiding, inkomste en beroep)
• Lewenstyl van respondente (hoë risiko faktore soos rook, die gebruik van
alkohol, verdowingsmiddeis, daaglikse dieët, oefening, hantering van
spanning en vryetydsaktiwiteite).
• Etnies-kulturele gelowe: gesondheid en siekte
• Geloofsgesondheid en siekte
• Omgewingsfaktore
• Gesondheidsdienste: toeganklikheid en bekostigbaarheid van dienste
Aanbevelings wat op die navorsingsbevindings gebaseer is, is die volgende:
• Beklemtoning van die herontwikkeling van gesondheidsvoorligting vir alle
ouderdomsgroepe.
• Die instel van In toelae vir individue wat nie in staat is om hulself en hulle
gesinne te help nie, is noodsaaklik vir die verbetering van hulle
gesond heidstatus .
• Die skep van meer werk om sosio-ekonomiese omstandighede in die
bevolking te verbeter
• Huidige gesondheidsdienste op pnmere gesondheidsorgvlak en
omgewingsfaktore wat die gesondheidstatus van die gemeenskap
beïnvloed, vereis dringend aandag.

Gambling in South Africa, with specific reference to the Western Cape gambling policyHuman, Pieter 12 1900 (has links)
Thesis (MPhil)--Stellenbosch University, 2000. / ENGLISH ABSTRACT: For the purposes of this study the term "gambling" refers only to casino style
gambling and does not necessarily include horse racing and the national lottery.
The study is partly based on the theoretical model for policy analysis as described by
Dunn in his book "Public Policy Analysis" (1994). The thesis is divided into two
sections. The first section deals mainly with the stage of monitoring and is a
retrospective analysis of the development of the gambling industry in seventeenth
and eighteenth century Venice and more recently in the United States, Australia,
Namibia and South Afiica prior to 1994.
The last section deals mainly with the stage of policy evaluation and questions the
possible discrepancies between the expected and actual gambling policy
performance in the Western Cape after 1994 when large scale gambling was
legalised throughout the country. It uses the recommendations of the Main Report on
Gambling in the Republic of South Afiica (Wiehahn Report) as a basis for the
evaluation of the Western Cape gambling policy from both a social and economic
perspective. More specifically the study attempts to shed light on the issues of the
problems related to the scientific research of gambling, the economic profile of
gamblers, the location of casinos, the displacement of capital and the correlation
between crime and gambling. / AFRIKAANSE OPSOMMING: Vir die doeleindes van hierdie studie word die term "gambling" slegs gebruik met
verwysing na dobbel in casinos en sluit nie noodwendig perdewedrenne en die
nasionale lotery in nie.
Die studie word gedeeltelik gebaseer op die teoretiese model vir beleids-analise soos
weergegee deur Dunn in sy boek "Public Policy Analysis" (1994). Die studie word
verdeel in twee afdelings. Die eerste gedeelte behandel die stadium van monitering

Structural adjustments in the wheat industry of the Western Cape ProvinceTroskie, Dirk Pieter 03 1900 (has links)
Dissertation (PhD (Agric))--Stellenbosch University, 2001. / ENGLISH ABSTRACT: The objective of this dissertation was to investigate the structural imbalances of the wheat industry
of the Western Cape Province and, with due recognition of a changing environment, to develop an
effective strategy for the industry.
It was found that the origins of the structural imbalances could be detected in the interaction
between policy, technological and demand factors and is not unique to the specific industry. The
farm problem provides an explanation for the instability of and downward pressure on wheat prices
as well as the sluggish adaptation to environmental change experienced in the wheat industry.
Internationally similar problems led to a whole range of policy measures. Relatively unique to
South African agriculture, but not only to the Western Cape wheat industry, is the circumstances
that gave rise to the current dual structure of the domestic agricultural sector. The origins of these
circumstances could be traced back to the Dutch settlement of the Cape in 1652 and the resulting
measures was later upheld under British rule. After the commercialisation of the local agricultural
sector following the discovery of diamonds in South Africa, certain measures were lobbied for at
the end of the 19th Century to protect white farmers. These measures were expanded in the 20th
Century and gave rise to the particular duality along ethnic lines of the South African agricultural
sector.
If it is accepted that the structural problems of the wheat industry are the result of political, policy,
technological and demand factors, the question of the potential future role of the sector, and more
specifically the wheat industry, can be asked. It was established that agriculture is a natural catalyst
for economic development through the provision of food, foreign exchange, manpower, and capital
formation as well as a market for industrial produce. Whereas the potential exists, agriculture has
not yet fulfilled this role in Southern Africa due to inconsistent domestic policy, adverse trade
regimes, inappropriate technology and problems encountered in the management of development.
This potential role of agriculture has been quantified for the Western Cape Province.
In the development of a strategy for an industry it is imperative to evaluate the future economic and
social environment. It was verified that in the next phase of economic development, towards
information societies, agriculture would still fulfil the functions previously mentioned. However, a
new and more esoteric role relating to identity could be added to this list in an information society.
Given the important role of agriculture as described in the previous section, intuition would lead
one to expect that government would play an important role in alleviating the structural problems of
the Western Cape wheat industry. However, contrary to this intuitive expectation it was found that,
in alleviating the problems of the Western Cape wheat industry, government intervention will be
largely limited to creating a favourable enabling environment. In getting to this conclusion the
theory of welfare economics, public choice and politician - voter interaction were explored. The
traditional wisdom has it that in searching for a Pareto-optimal state, or at least a second-best
solution, pressure group activities may play an important role. This is seen as important due to the
difficulties, as indicated by Arrow's impossibility theorem, in transforming individual preferences
into political preference functions. However, numerous examples have shown that pressure group
activities may only playa marginal role in influencing the final outcome. The underlying structural
characteristics of the national and provincial economies may be a more important determinant. This
became more certain as the way politicians perceived agriculture before and after the 1994 political
transition was analysed.
It follows that a strategy for the wheat industry of the Western Cape will take the global, social,
policy, natural and consumer environment into account and both the strategy and the industry will
have to be self-reliant. It was argued that a solution would be found in changing the slope
(elasticity) of the demand and supply functions for agricultural produce. With the aid of a spatial
model developed the impact of the different elements of the strategy on the profitability of wheat
production in the Western Cape was evaluated. This model took into consideration the yield
potential for wheat, the gross and net margin of wheat production, spatial dispersion, transport costs
and also made provision for different intermediate markets. It was found that each of the
components of the strategy would substantially contribute to a more profitable wheat industry for
the Western Cape. The combined effect of the strategy would result in a 97 percent decrease in the
area where wheat production is unprofitable. Profitable production of wheat would be possible on
99,3 percent of the total area that is suitable for rainfed wheat production. The production of wheat
would be highly profitable at a margin of more than R200 per ton on more than 1,1 million hectares
(77,1% of the total area).
It is concluded that, while taking the global, social, policy, natural and consumer environment into
account and without relying on government, a strategy could be developed that will rectify the
structural problems of the Western Cape wheat industry. / AFRIKAANSE OPSOMMING: Die doel van hierdie proefskrif was om die strukturele wanbalanse van die koringbedryf in die Wes-
Kaap Provinsie te ondersoek en, om met erkenning aan 'n veranderde omgewing, 'n effektiewe
strategie vir die bedryf te ontwikkel.
Dit is bevind dat die oorsprong van die strukturele wanbalanse uit die interaksie tussen beleid-,
tegnologiese- en vraagfaktore spruit en dat die wanbalanse nie uniek is tot die bedryf nie. 'n
Verklaring vir die onstabiliteit van- en afwaartse druk op koringpryse, sowel as die trae aanpassings
van die bedryf by omgewingsveranderings, word deur die plaasprobleem gebied. Soortgelyke
probleme het globaal tot 'n verskeidenheid van beleidmaatreëls aanleiding gegee. Wat wel uniek is
tot die Suid-Afrikaanse landbou, maar nie tot die plaaslike koringbedryf nie, is die omstandighede
wat tot die huidige dualistiese struktuur van die landbou sektor aanleiding gegee het. Die oorsprong
van die omstandighede kan teruggespoor word tot die Hollandse besetting van die Kaap in 1652 en
die gepaardgaande maatreëls wat ook onder Britse bewind in stand gehou is. Na die
kommersialisering van die plaaslike landbou sektor, wat op die ontdekking van diamante in Suid-
Afrika gevolg het, is bepaalde maatreëls aan die einde van die 19de eeu deur drukgroepe beding ten
einde blanke boere te beskerm. Hierdie maatreëls is in die 20ste eeu uitgebrei en het die unieke
dualiteit op etniese gronde van die Suid-Afrikaanse landbou sektor tot gevolg gehad.
Met aanvaarding daarvan dat die strukturele wanbalanse van die koringbedryf die resultaat is van
politieke, beleid, tegnologiese en vraag faktore, kan dit gevra word of die sektor, en meer spesifiek
die koringbedryf, nog 'n rol te speel het. Dit is gevind dat landbou 'n natuurlike katalisator vir
ontwikkeling kan wees deur die verskaffing van voedsel, buitelandse valuta, mannekrag, kapitaal
vorming en 'n mark vir industriële goedere. Ten spyte van die bestaande potensiaal kon landbou
nog nie hierdie rol in Suidelike Afrika vervul nie, hoofsaaklik as gevolg van inkonsekwente
binnelandse beleid, onvriendelike handelsomgewings, nie-geskikte tegnologie en ontwikkelingsbestuur
probleme. Die potensiële rol van landbou in die Wes-Kaap Provinsie is gekwantifiseer.
Dit is belangrik om tydens die ontwikkeling van 'n strategie vir 'n bedryf ook die toekomstige
ekonomiese en sosiale omgewing in aanmerking te neem. Dit is bevestig dat in die volgende fase
van ekonomiese ontwikkeling, dié van 'n inligtings gemeenskap, landbou steeds die voorgenoemde
funksies sal vervul. 'n Nuwe en meer esoteriese funksie, gefokus op identiteit, kan egter in 'n
inligtingsgemeenskap tot die lys toegevoeg word.
Gegewe hierdie belangrike rol van landbou kan intuïtief verwag word dat die owerheid bereid sal
wees om 'n belangrike bydrae te maak tot die verligting van die strukturele probleme van die Wes-
Kaapse koringbedryf. Teenstrydig met hierdie intuïtiewe verwagting is egter bevind dat owerheids
betrokkenheid hoofsaaklik beperk sal wees tot die skepping van 'n gunstige en bemagtigende
omgewing. Ten einde hierdie gevolgtrekking te bereik is welfaart ekonomie, publieke keuse en
politici - kieser interaksie teorie bestudeer. Volgens tradisionele denke kan drukgroep aktiwiteite
'n belangrike rol speel in die soeke na 'n Pareto-optimale staat, of ten minste in die soeke na 'n
tweede-beste oplossing. Weens probleme in die transformasie van individuele voorkeure na
politieke voorkeur funksies, soos beskryf deur die onmoontlikheidsteorie van Arrow, word hierdie
aktiwiteite as belangrik geag. Veelvuldige voorbeelde dui egter daarop dat drukgroep aktiwiteite
slegs 'n marginale rol kan speel in die beïnvloeding van finale uitkomste. Dit blyk dat
onderliggende eienskappe van die nasionale en provinsiale ekonomië meer bepalende faktore kan
wees. Hierdie vermoede is bevestig namate die politieke persepsie van die landbou voor en na die
1994 politieke transformasie geanaliseer is.
Uit die voorafgaande is dit duidelik dat 'n strategie vir die koringbedryf van die Wes-Kaap die
internasionale, sosiale, politieke, natuurlike en verbruikers omgewing in aanmerking sal moet neem.
Dit is ook duidelik dat beide die strategie en die bedryf self onderhoudend sal moet wees. Dit word
aangevoer dat 'n oplossing gevind kan word indien die helling (elastisiteit) van die vraag en aanbod
funksies van landbouprodukte aangepas kan word. Met behulp van 'n ruimtelike model wat
ontwikkel is, is die impak van die verskillende elemente van die strategie op die winsgewendheid
van koringproduksie in die Wes-Kaap geëvalueer. Hierdie model het onder meer die opbrengs
potensiaal van koring, die bruto en netto marge van koringproduksie, ruimtelike verspreiding,
vervoerkoste en verskillende intermediêre markte in aanmerking geneem. Dit is bevind dat elk van
die elemente van die strategie beduidend tot winsgewende koringproduksie in die Wes-Kaap kan
bydra. Die strategie kan daartoe lei dat die oppervlakte met nie-winsgewende koringproduksie met
97 persent sal afneem. Koring kan winsgewend verbou word op 99,3 persent van die area geskik
vir droëland produksie. Terselfdertyd sal koring, teen 'n marge van R200 per ton, hoogs
winsgewend verbou kan word op nagenoeg 1,1 miljoen hektaar (77,1 persent van die totale area).
Ten slotte blyk dit dat, met inagneming van die internasionale, sosiale, politieke, natuurlike en
verbruikers omgewing, en sonder dat op owerheids ondersteuning staatgemaak word, 'n strategie
ontwikkel kon word wat die strukturele wanbalanse van die Wes-Kaapse koringbedryf kan oplos.
