Dissertation (PhD)--University of Stellenbosch, 2003. / ENGLISH ABSTRACT: Riparian vegetation has received a lot of attention in South Africa recently, mainly because of its importance in bank stabilization and its influence on flood regimes and water conservation. The upper reaches have thus far received the least of this attention because of their inaccessibility. This study mainly focuses on these reaches where riparian vegetation is still mostly in a pristine state. The study area chosen for this purpose is the Hottentots Holland Mountains in the Southwestern Cape, the area with the highest rainfall in the Cape Floristic Region, which is very rich in species. Five rivers originate in this area and the vegetation described around them covers a large range of habitats, from high to low altitude, with different geological substrates and different rainfall regimes. All of these rivers are heavily disturbed in their lower reaches but are still relatively pristine in their upper reaches. All of them are dammed in at least one place, except for the Lourens River. An Interbasin Transfer Scheme connects the Eerste-, Berg- and Riviersonderend Rivers. The water of this scheme is stored mainly in Theewaterskloof Dam. Another big dam for water storage, Skuifraam Dam, will be built on the Berg River near Franschhoek in the nearby future. In order to study the vegetation around a river, a zonation pattern on the river bank is described and several physical habitats are recognized. A primary distinction is made between a Wet Bank (flooding at least once a year) and a Dry Bank (flooding less than once a year). The Dry Bank is further subdivided into a Lower Dynamic, a Shrub/Tree and a Back Dynamic Zone. In the lower reaches these zones are very distinct, but in the upper reaches of a river they tend to blend into each other and some zones can be absent or very narrow. Vegetation has been sampled in transects across the riverbed, following the Braun-Blanquet method. Additional vegetation samples have been recorded in the bogs and mires at the sources of the rivers. Vegetation structure and physical habitat has been described to contribute to the description of the vegetation types. In order to understand the environmental processes that determine the vegetation, environmental parameters were recorded in every vegetation sample, such as, slope, aspect, rockiness and soil variables. The classification of the vegetation samples resulted in the identification and subsequent description of 26 riverine and 11 mire communities. The riverinecommunities have been subdivided into ten Community Groups, including a group of Aquatic communities and three groups of Wet Bank communities. The main distinction within the Wet Bank Zone is the importance of erosion or deposition as a driving force of the ecosystem. Three groups of Fynbos communities are identified in the Back Dynamic Zone, with Asteraceous Fynbos occurring on shales and granites, Ericaceous Fynbos occurring on Table Mountain Group sandstones and Transitional Fynbos on a variety of substrates. One community group is characterized by the dominance of Cliffortia odorata, which shows affinity with some renosterveld communities known from literature. The two final groups contain the Afromontane Forests and Riparian Scrub communities, respectively. Discharges are calculated from data recorded at existing gauging weirs. The recurrence intervals, inundation levels and stream power of several flood events are derived from these data and are extrapolated to upstream sites. It appears that most vegetation types in the zonation pattern on the riverbank can be explained by these flood events, except for the Afromontane Forests, which are dependent on other sitespecific factors including protection from fire. Constrained and unconstrained ordinations are used to relate vegetation patterns to the environment. The vegetation is determined by three environmental gradients, operating at different scales. The lateral gradient across the riverbed is mainly determined by inundation frequency and stream power, which are difficult to measure in rocky mountain situations, although variables like distance from the water’s edge, elevation above the water level and rockiness are correlated to them. The longitudinal gradient is the gradient along the length of the river, from high to low altitude. This gradient has the least influence on the riparian vegetation. The geographical gradient reflects the large-scale climatic processes across the mountain range. This gradient accounts for the biggest part of the total explained variation. Important variables are especially the ratio between the summer and winter rainfall and the geological substrate. In the Fynbos Biome, where gamma diversity is extremely high, large-scale environmental processes are important in azonal vegetation as well. The most species-rich vegetation associated with the rivers is found furthest from the water’s edge at intermediate altitudes. Knowledge about the vegetation types and environmental processes in Western Cape rivers is essential for monitoring and maintaining these special ecosystems. Specific threats are related to possible abstraction of water from theTable Mountain Group aquifer and from climate change, which might result in an overall drying of the ecosystem. / AFRIKAANSE OPSOMMING: Riviere se oewerplantegroei kry die laaste tyd baie aandag in Suid-Afrika, hoofsaaklik vanweë die belang vir die beheer van vloede, stabilisasie van die oewers en die bewaring van drinkwater. Die hoë-liggende dele van die riviere het tot dusver die minste aandag geniet omdat hulle tot ’n groot mate ontoeganklik is weens die onherbergsame terrein waarin hulle geleë is. In hierdie studie is daar veral na bergstrome gekyk waar die plantegroei nog taamlik natuurlik en onversteur is. Die studiegebied wat vir hierdie doel gekies is, is die Hottentots-Holland berge in die Wes-Kaap. Die gebied het die hoogste reënval in die Kaapse Floristiese Ryk en is ook baie ryk aan spesies. Vyf riviere het in hierdie gebied hulle oorsprong. Die plantegroei wat hier voorkom sluit ‘n wye reeks habitatte in: van hoog tot laag in hoogte bo seespieël, verskeie geologiese substrate asook verskillende reënval patrone. Al die vyf riviere wat ondersoek is, is baie versteur in hul onderlope, maar is nog grotendeels natuurlik in hul hoë-liggende dele. Almal is reeds opgedam deur een of meer damme, behalwe die Lourensrivier. ’n Tussenopvanggebied-oordragskema verbind tans die Eerste-, Berg- en Riviersonderendriviere met mekaar. Die water uit hierdie riviere word tans hoofsaaklik in die Theewaterskloofdam opgegaar. ’n Verdere groot opgaardam, die sogenaamde Skuifraamdam, word binnekort in die Bergrivier te Franschhoek gebou. Al die riviere se onderlope is tot ’n mindere of meerdere mate vervuil met landbou- en rioolafvoerprodukte. Uitheemse indringerplante, wat die natuurlike oewerplantegroei verdring, skep veral probleme stroomaf van plantasies en dorpe. Om die plantegroei van die rivieroewers na te vors, te klassifiseer en te beskryf, is variasies in die fisiese omgewing bepaal en korrelasies gesoek om die verspreiding van die plantegroei te verklaar. Die belangrikste verdeling in die oewerplantegroei wat gevind is, is tussen die Nat-oewersone (dit word meer as een keer per jaar oorstroom) en die Droë-oewersone (dit word minder as een keer per jaar oorstroom). Die Droë-oewersone word verder onderverdeel in die Laerdinamiesesone, die Boom/Struiksone en die Agter-dinamiesesone. In die laer dele van die rivier is hierdie soneringspatrone baie duidelik, maar in die boonste dele van die rivier kan die onderverdelings dikwels nie van mekaar onderskei word nie omdat hulle gemeng is, of kan die sones baie smal wees of selfs heeltemal afwesig wees.Die plantegroei is gemonster in transekte wat dwarsoor die rivierloop uitgelê is. Die Braun-Blanquet monstertegniek is gevolg. Bykomende monsterpersele is opgemeet in die moerasse in die boonste dele van die berg-opvanggebiede. Om die omgewingsprosesse wat die plantegroei bepaal te verstaan, is ’n aantal omgewingsfaktore in elke monsterperseel aangeteken, wat, onder andere, helling, aspek en bedekking van rotse ingesluit het, terwyl die variasie in samestelling van die bodem ook aangeteken is. Die klassifikasie van die plantegroei het tot die beskrywing van 26 plantgemeenskappe in die riviere en 11 gemeenskappe in die moerasse gelei. Die struktuur van die plantegroei asook kenmerke van die fisiese habitat is in die beskrywing van die plantegroei-eenhede ingesluit. Die gemeenskappe in die riviere is onderverdeel in tien gemeenskapsgroepe. Daar is een gemeenskapsgroep wat die akwatiese gemeenskappe en drie wat die Nat-oewersone gemeenskappe insluit. Die belangrikste verskille tussen die verskillende Nat-oewersone gemeenskappe word bepaal deur die mate waartoe erosie of deposisie voorkom. Daar is ook drie gemeenskapsgroepe van Fynbos onderskei wat in die Agter-dinamiesesone voorkom. Dit sluit in die Aster-fynbos op die skalies en graniete, die Erica-fynbos op die sandstene en die Oorgangs-fynbos op gemengde substrate. Een gemeenskapsgroep is deur die dominansie van Cliffortia odorata gekenmerk. Dit toon verwantskap met renosterveld gemeenskappe wat reeds in die literatuur beskryf is. Die laaste twee groepe sluit die Afromontane woude en Oewerstruikbosse in. Die waterafloop is bereken deur middel van data verkry vanaf bestaande keerwal meetstasies. Die herhalings-intervalle, oorstromingsdiepte en vloei-sterkte van verskillende vloedtipes word vanaf hierdie data afgelei en stroomop geekstrapoleer. Die meeste plantegroeivariasie op die oewers kan deur die vloede verklaar word, behalwe in die geval van die Afromontane woude, wat deur ander omgewingsfaktore bepaal is. Beperkte en onbeperkte ordinasie is gebruik om die verband tussen die plantegroeipatrone en die omgewing te bepaal. Die plantegroei se verspreiding is bepaal deur drie omgewingsgradiënte, wat op verskillende skale ‘n uitwerking het. Die laterale gradiënt oor die rivierbedding is hoofsaaklik bepaal deur oorstromingsfrekwensie en stroomvloeisterkte. Hierdie veranderlikes is moeilik bepaalbaar, alhoewel ander soos, afstand vanaf die rivier, hoogte bo watervlak en bedekking van rotse, wat hieraan gekorreleer is, wel meetbaar is. Die lengte gradiënt,dit is die gradiënt wat van oorsprong na einde langs die lengte van die rivier teenwoordig is, het die minste invloed op die plantegroei. Die geografiese gradiënt weerspieel die grootskaalse klimaatsveranderinge oor die bergreeks. Deur hierdie gradiënt word die grootste deel van die totale variasie tussen die monsters verklaar. Die belangrikste veranderlikes is die verhouding van somer- teenoor winter-reënval en die geologiese substraat. Soortgelyk aan die fynbos in die Fynbosbioom, waar gammadiversiteit buitegewoon hoog is, is die grootskaalse omgewingsprosesse, ook vir asonale oewerplantegroei, baie belangrik. Die spesierykste plantegroei rondom die rivier word die verste van die oewer op gemiddelde hoogtes bo seespieël gevind. Kennis oor die plantegroei en die omgewingsprosesse in die riviere in die Wes-Kaap is belangrik vir die monitering en effektiewe beheer van hierdie besondere ekosisteem. Spesifieke bedreigings is gekoppel aan die potensiële ontginning van water uit die akwifer in die Tafelberggroep-sedimente asook deur grootskaalse klimaatsveranderinge waartydens die hoeveelheid water, volgens voorspellings, waarskynlik sal afneem in hierdie ekosisteem.

Multilingualism has always been a feature of South African Education. It is only in recent years that a particular form of linguistic diversity has become unmanageable for schools implementing the official English/Afrikaans bilingual model associated with the previous regime. The subject of this study is a remedial language enrichment or support programme instituted as a response to multilingualism in the junior primary section in a parallel medium primary school in the Western Cape.

There is a growing sense of apathy and lack of focus amongst the youth, which contributes to the threat of social integration. Constructive alternatives are therefore needed to curb gangsterism, drug abuse and other criminal activities among youth at risk. It has become imperative to challenge the present situation in which crime has become one of the most attractive options facing our youth. Through a programme of contructive engagement, a substantial difference can be made in their rehabilitation and ultimately their active participation in building a safer society. A strong emphasis should be placed on the development and implementation of effective restorative justice principles, alternative sentencing and community-based rehabilitation programmes, particularly for young people in marginalised communities.

The Table Mountain group aquifer system has the potential to be an important supply of water. Although the aquifer system is used to some extent, a number of aspects relating to the aquifer system are poorly understood and unquantified. This study aimed to take into consideration the importance of differenct ecosytems, which is essential in predicting the effects of groundwater abstruction. However, the ecological requirements of systems that depend on groundwater are poorly understood. This project identified &quot / type areas&quot / for further detailed research into the impacts of large-scale groundwater abstraction from the Table Mountain group aquifer system based on the nature and functioning of ecosystems across groundwater dependent ecosystem boundaries of a regional scale.

Increasingly, organisations are realising that they have to establish an equitable balance between the employee&rsquo / s contribution to the organisation and the organisation&rsquo / s contribution to the employee. Establishing this balance is one of the main reasons to reward and recognise employees. Organisations that follow a strategic approach to creating this balance focus on the three main components of a reward system, which includes, compensation, benefits and recognition (Deeprose, 1994). Studies that have been conducted on the topic indicates that the most common problem in organisations today is that they miss the important component of recognition, which is the low-cost, high-return ingredient to a well-balanced reward system. A key focus of recognition is to make employees feel appreciated and valued (Sarvadi, 2005). Research has proven that employees who get recognised tend to have higher self-esteem, more confidence, more willingness to take on new challenges and more eagerness to be innovative (Mason, 2001). The aim of this study is to investigate whether rewards and recognition has an impact on employee motivation. A biographical and Work Motivation Questionnaire was administered to respondents (De Beer, 1987). The sample group (N= 184) consists of male and female employees on post-grade levels 5 to 12. The results of the research indicated that there is a positive relationship between rewards, recognition and motivation. The results also revealed that women, and employees from non-white racial backgrounds experienced lower levels of rewards, recognition and motivation. Future research on the latter issues could yield interesting insights into the different factors that motivate employees. Notwithstanding the insights derived from the current research, results need to be interpreted with caution since a convenience sample was used, thereby restricting the generalisability to the wider population.

The research explored the new health care service vehicle of South African with special reference to health service providers in Western Cape Department of health for the period 1995-2001. A study was made of the District Health System and the shift of emphasis from tertiary and secondary level of health care to the more cost effective Primary Health Care Service rendered at District level.

Motivation is considered to be the desired positive willingness that prompts a person to action. The factors that influence or lead to this positive willingness, are considered to be motivation factors, and include specific needs, wants, drives or impulses (Hersey &amp / Blanchard, 1988).<br /> <br /> People are motivated by different things, both intrinsic and extrinsic factors. For some, it is power and money that motivate them while for others, it is flexibility or a social workplace. According to Herzberg&rsquo / s theory, intrinsic factors are motivators or satisfiers and can be described as a person's relationship with what she or he does, many related to the tasks being performed (Buitendach &amp / De Witte, 2005 / Mehta, Anderson &amp / Dubinsky, 2000). Extrinsic factors, also known as hygiene factors or dissatisfiers, have to do with a person's relationship to the context or environment in which she or he performs a job (Buitendach &amp / De Witte, 2005 / Mehta et al., 2000). Some individuals are highly motivated by both intrinsic and extrinsic rewards. This is supported in a study amongst medical students (Beswick, 2002). In another study by Shim, Gehrt and Goldsberry (1999), it was found that students entering a career in retail viewed intrinsic aspects as the most important predictor of a retail career, followed by lifestyle flexibility aspects and then extrinsic aspects. Furthermore, research within a service organisation has indicated that various biographical factors have an influence on work motivation (Bezuidenhout, 2001). However, limited research has been conducted to determine whether biographical factors have an influence on work motivation within the retail industry.<br /> <br /> The aim of the study was to investigate the motivation of retail managers in a retail organisation in the Western Cape. Furthermore, it investigates whether the motivation levels of retail managers are influenced by their biographical variables. The Work Satisfaction and Motivation Questionnaire developed by De Beer (1987) and a self-developed biographical questionnaire was administered to elicit work content, promotion, supervision, reward and recognition in relation to work motivation. The questionnaires were distributed to the target population (n=236) of retail managers which were inclusive of store managers, store assistant managers and department managers. Convenience sampling was used to draw a sample (n=109) of male and female retail managers. Statistical analyses involved both descriptive and inferential statistics (ANOVA, Multiple Regression Analysis, Pearson&rsquo / s Correlation Co-efficient and Scheffe&rsquo / s test). The results revealed that there is a significant positive relationship between the investigated dimensions of work motivation and satisfaction. It was found that the investigated dimensions of motivation only account for 49.5% of the variance in total motivation experienced by retail managers. Furthermore, significant differences were found between the biographical variables and responses to the questionnaire. It is suggested, for future research that a proportionate stratified random sample be drawn which will allow the findings of the study to be reliably generalised to the population. Furthermore, it is also recommended that future research consider dimensions of motivation, such as, achievement, responsibility, security, autonomy, feedback and morale, which are not investigated in this study.

<p>In South Africa, some of the problems experienced in moving towards an inclusive education system are a lack of resources, a lack of commitment and a poor understanding of how to aid successful inclusion. The implementation of inclusion is a process that has been initiated by Education White Paper 6 (Dept. of Education, 2001) and is still in the process of developing the necessary education support. This study aimed to investigate the collaboration between the District Based Support Team, the School Based Support Team and the School Governing Body which represents the parents. The main objective was to investigate how the above bodies support and assist learners who experience barriers to learning, development and participation through a collaborative and consultative problem approach.</p>

<p>In virtually any field of endeavour today, access to information is a prerequisite for success. Libraries form the repositories with user-friendliness their mission. This has lead to the need for new ways to evaluate library performance. Astute library managers will plan for such developments, taking into account current and future trends that impact on library services. Library services are also affected, for example, by financial considerations and staffing problems. Further complicating matters are the demands of their clients who have developed increased expectations of improved service, and also a desire for more self-service opportunities. Such changes raise the question: &ldquo / to what extent can libraries apply business performance management techniques to assess their performance.&rdquo / This, then, is the research question for this study.</p> <p><br /> This work will evaluate library performance with the aim of improving service management.
