The past few months have seen our courageous youth take to the streets to demonstrate their disgust against this system of exploitation and oppression. This militant fervour has touched many young hearts and minds. However, there is always the danger that these energies will burn out and dissipate. Demoralisation can so easily set in if these energies are not constructively channeled. "Channeled into what?” you may ask. ORGANISATIONS. It is only through strong organisations which attempt to give guidance and direction that meaningful action can be undertaken. The WCYL recognises the important need for students to begin to discuss broader issues such as The History of Struggle in S.A. or The Nature of S.A. Society. It is only when students begin to grapple with broader issues such as these, together with more specific ones, in a co-ordinated manner, will their actions be more effective. To this end has "GET ORGANISED" been designed. The handbook is intended as a guide for students in their efforts to organise SRC’s, awareness programmes, among other things, in schools.

Thesis (MScAgric)--Stellenbosch University, 2012. / ENGLISH ABSTRACT: This study looked at the incidence, etiology and epidemiology of core rot of apples in orchards situated in the Western Cape, South Africa. Core rot is a post-harvest disease, with three symptoms, namely mouldy core (MC), dry core rot (DCR) and wet core rot (WCR). These symptoms are caused by various pathogenic fungi, including Alternaria and Penicillium. Although MC is not economically important, DCR and WCR are, as they affect the flesh of the fruit. Core rot occurs worldwide in susceptible apple cultivars such as ‘Starking’ and ‘Red Delicious’. These cultivars have a wider, open calyx tube which results in an open core area. In South Africa, core rot of apples are important post-harvest diseases and losses of between 5 and 12% occur in apple cultivars. An in depth literature search was done on core rot including literature on each core rot symptom, the genuses Alternaria and Penicillium, molecular identification and techniques, disease incidence and its economic importance, various inoculum sources, pathogenicity of core rot organisms and integrated management of core rot. This study included two research chapters, with seven objectives, namely, to 1, determine the incidence of core rot in apples from commercial orchards both pre- and post-harvest; 2, to identify the causal organisms associated with core rot symptoms; 3, to identify potential sources of inoculum of core rot pathogens and determine whether there is synergism between Alternaria and Tarsonemus mites associated with core rot; and 4, to determine whether the fungicide Bellis®, used a full bloom application, can be used to manage core rot in South Africa; 5, to identify the species of Alternaria and Penicillium sampled from core rot symptomatic fruit and inoculum sources (air, apple mummies and mites), using morphological and molecular methods; 6, to compare Penicillium species isolated from pre- and post-harvest WCR symptomatic fruit, using molecular species identification methods and 7, to compare and to select the most reliable pathogenicity test for use in future research. The total decay incidence for Ceres is considerably higher than the previous losses indicated in literature. Pre-harvest core rot, which was confirmed by previous studies, had a higher incidence of each core rot symptom than previously indicated. The two most frequently isolated causal organisms were Alternaria and Penicillium. Other organisms isolated and then identified from the symptoms were Fusarium, Cladosporium, Epicoccum, Ulocladium, Stemphylium, Phoma, Botryosphaeria, Botrytis, Trichoderma, Verticillium, Paecilomyces and Gliocladium. Three inoculum sources, air, mummies and mites, were regarded as potential sources of infection for core rot. During this study the sources of infection were verified and core rot causing organisms were isolated from these sources. Alternaria was isolated from air inoculum samples, but was not found on the other two sources. This dismissed the hypothesis that there was a possible synergism between Alternaria and Tarsonemus mites. Penicillium species were isolated from all three sources, more frequently from the mummies and mites. Bellis® was applied three times during the bloom period. The subsequent results showed a significant difference between the control and Bellis® treated treatments with the treated fruit having a significant higher incidence than the controlled fruit. No control was observed with this result and managing core rot with only Bellis® is not advisable. Alternaria species were identified using the following genetic loci, ITS, OPA1-3, 2-1 and 10-2 as well as endoPG. Isolates from pre- and post-harvest symptoms and air inoculum were identified using each of the genetic loci. Alternaria arborescens was one of the species that was identified. The other isolates obtained were A. alternata, A. tenuissima, A. gaisen, A. dumosa, A. turkisafria and A. perangusta. Separating combined species was not possible. Another molecular technique, ISSR, was used to identify Alternaria species. This technique, after multiple re-runs, did not give consistent results and species could not be identified. Penicillium species were identified using the genetic loci ITS for isolates collected from pre- and post-harvest symptoms and inoculum sources. Thirteen clades were identified, including the species P. ramulosum, P. sp. (aff. cecidicola), P. sp (aff. dendriticum), P. expansum, P. paneum, P. solitum, P. crustosum , P. brevicompactum, P. novae-zeelandiae, P. glabrum and P. rugulosum. Penicillium expansum and P. ramulosum had the highest distribution between the isolates. Pre- and post-harvest WCR isolates were identified using the partial beta-tubulin PCR-RFLP method, and comparing different banding-patterns. The species identified using this method were P. expansum, P. ramulosum, P. sp. (aff. cecidicola), P. sp (aff. dendriticum), P. rugulosum, P. chermesinum and P. glabrum. Penicillium ramulosum and P. expansum had the highest incidence with P. ramulosum occurring more frequently pre-harvest than post-harvest and P. expansum occurring more frequently post-harvest. Five methods, previously published, were compared to select the most reliable pathogenicity test. The methods included surface wounding of an apple with colonised toothpicks, surface wound inoculated with a pipette, inoculation of an open mesoderm core cavity, deep and non-wounding of apple fruit with colonised toothpicks. The surface wounding with a colonised toothpick gave the most reliable results and can be used in industry as a pathogenicity test for Alternaria in apples. This study contributed to our understanding on the incidence and etiology of core rot in the Western Cape as well as in identifying inoculum sources from where infection can take place in the orchard. The results for the fungicide trial were not as anticipated and more research is required on selecting fungicides for the control of core rot in South African orchards. Although molecular techniques reduce the time in identifying fungal species, it is costly and mistakes can occur due to contamination. Identification of species can be incorrect when using a Genbank as the sequence information may be incorrect. Molecular techniques, though a good tool in identifying species, should be combined with morphological characteristics to ensure more accurate results. / AFRIKAANSE OPSOMMING: Hierdie studie het gekyk na die insidensie, etiologie en epidemiologie van kernvrot in appels vanuit boorde in die Wes-Kaap, Suid-Afrika. Kernvrot is ‘n na-oes iekte, met drie simptome, naamlik beskimmelde kern, droë kernvrot en nat kernvrot. Hierdie simptome word veroorsaak deur verskillende patogeniese swamme, insluitend Alternaria en Penicillium. Alhoewel beskimmelde kern nie ekonomies belangrik is nie, is droë en nat kernvrot wel belangrik, omdat hulle die vrug se vlees affekteer. Kernvrot kom wêreldwyd voor in vatbare kultivars soos ‘Starking’ en ‘Red Delicious’. Hierdie kultivars het ‘n wye, oop kelkbuis wat ‘n oop kern area veroorsaak. In Suid-Afrika is kernvrot van appels ‘n belangrike na-oes siekte en verliese tussen 5 en 12% kom voor in appel kultivars. ‘n In diepte literatuurstudie is gedoen omtrent kernvrot, insluitend literatuur omtrent elke kernvrot simptoom, die genera Alternaria en Penicillium, molekulêre identifikasie en tegnieke, siekte insidensie en sy ekonomiese impakte, verskillende inokulum bronne, patogenisiteit van kernvrot organismes en die geïntegreerde bestuur van kernvrot. Hierdie studie sluit in twee navorsings hoofstukke met sewe doelwitte, naamlik om 1, te bepaal wat die insidensie van kernvrot in appels is vanuit kommersiële boorde vir beide voor en na-oes; 2, om veroorsakende organismses wat met kernvrot simptome geassosieër is te identifiseer; 3, om potensiële inokulum bronne van kernvrot patogene te identifiseer en te bepaal of daar ‘n sinergisme tussen Alternaria en Tarsonemus myte, wat geassosieër is met kernvrot, is; 4, om te bepaal of die fungisied Bellis®, gebruik as ‘n volblom toediening, gebruik kan word om kernvrot in Suid-Afrika te beheer; 5, om die Alternaria en Penicillium spesies wat uit simptomatiese kernvrot vrugte en inokulum bronne geïsoleer is te identifiseer; 6, om Penicillium spesies, wat uit voor en na-oes nat kernvrot simptome geïsoleer is, te vergelyk deur gebruik te maak van molekulêre spesies identifiserings metodes en 7, om die betroubaarste patogenisiteits toets te vergelyk en selekteer vir toekomstige gebruik. Die totale bederfde insidensie vir Ceres is heelwat hoër as die vorige verliese wat aangedui is in literatuur. Vooroes kernvrot, wat deur vorige studies bevestig is, het ‘n hoër insidensie vir elke kernvrot simptoom gehad as wat voorheen aangedui is. Die twee geïsoleerde veroorsakende organismes wat die meeste voorgekom het was Alternaria en Penicillium. Ander organismes wat geïsoleer en geïdentifiseer is vanuit die simptome was Fusarium, Cladosporium, Epicoccum, Ulocladium, Stemphylium, Phoma, Botryosphaeria, Botrytis, Trichoderma, Verticillium, Paecilomyces en Gliocladium. Drie inokulum bronne, lug, gemummifiseerde vrugte en myte, is geag as potensiële bronne van infeksie vir kernvrot. Gedurende hierdie studie is hierdie bronne bevestig en kernvrot veroorsakende organismes is uit die bronne geïsoleer. Alternaria is geïsoleer vanuit die lug inokulum monsters, maar is nie geïsoleer vanuit die ander twee bronne nie. Dus die hipotese dat daar ‘n sinergisme tussen Alternaria en Tarsonemus myte is, is verwerp. Penicillium spesies is geïsoleer vanuit al drie bronne, maar meer gereeld vanuit die gemummifiseerde vrugte en die myte. Bellis® is drie keer gedurende die bot toegedien. Die daaropvolgende resultate het ‘n betekenisvolle verskil tussen die kontrole en Bellis® beheerde behandelings getoon, met die behandelde vrugte wat ‘n betekenisvolle hoër insidensie gehad het as die kontrole vrugte. Geen beheer is waargeneem nie en beheer van kernvrot met net Bellis® word nie aanbeveel nie. Alternaria spesies is geïdentifiseer deur die volgende genetise lokusse, ITS, OPA1-3, 2-1 en 10-1, asook endoPG. Isolate van voor en na-oes simptome en lug inokulum is geïdentifiseer deur elk van die genetiese lokusse. Alternaria arborescens is een van die spesies wat geïdentifiseer is. Ander isolate wat verkry is, was A. alternata, A. tenuissima, A. gaisen, A. dumosa, A. turkisafria and A. perangusta. Om gekombineerde spesies te skei was nie moontlik nie. ‘n Ander molekulêre tegniek, ISSR, was gebruik om Alternaria spesies te identifiseer. Hierdie tegniek, na menigte probeerslae, het nie konsekwente resultate gegee nie en spesies kon nie hiermee geïdentifiseer word nie. Penicillium spesies, versamel vanuit voor en na-oes simptome en inokulum bronne, is geïdentifiseer deur die genetiese lokus ITS. Dertien ‘clades’ is geïdentifiseer, insluitend die spesies P. ramulosum, P. sp. (aff. cecidicola), P. sp (aff. dendriticum), P. expansum, P. paneum, P. solitum, P. crustosum , P. brevicompactum, P. novae-zeelandiae, P. glabrum en P. rugulosum. Penicillium expansum en P. ramulosum het die hoogste distribusie tussen die isolate. Voor en na-oes nat kernvrot isolate is geïdentifiseer deur die deels beta-tubulin PCR-RFLP metode, en verskillende band patrone te vergelyk. Die spesies geïdentifiseer deur hierdie metode is P. expansum, P. ramulosum, P. sp. (aff. cecidicola), P. sp (aff. dendriticum), P. rugulosum, P. chermesinum en P. glabrum. Penicillium ramulosum en P. expansum het die hoogste insidensie gehad met P. ramulosum wat meer dikwels vooroes voorkom en P. expansum wat meer dikwels na-oes voorkom. Vyf metodes, wat voorheen gepubliseer is, is vergelyk om die betroubaarste patogenisiteits toets te selekteer. Die metodes sluit in die oppervlak wond van ‘n appel met ‘n gekoloniseerde tandestokkie, oppervlak wond geïnokuleer met ‘n pipette, inokulasie van ‘n oop mesoderm kern area, diep besering en nie-besering van die appel met gekoloniseerde tandestokkies. Die oppervlak besering met ‘n gekoloniseerde tandestokkie het die betroubaarste resultate gegee en kan in die industrie gebruik word as ‘n patogenisiteits toets vir Alternaria in appels. Hierdie studie het bygedra tot ons kennis van die insidensie en etiologie van kernvrot in die Wes-Kaap sowel as die identifisering van die inokulum bronne, van waar die infeksie in die boord kan plaasvind. Die resultate vir die fungisied proef was nie wat ons verwag het nie en meer navorsing word benodig om fungisiede te selekteer vir die beheer van kernvrot in Suid-Afrikaanse boorde. Alhoewel molekulêre tegnieke die tyd verminder om ‘n swam spesie te identifiseer, is dit wel duur en foute kan voorkom as gevolg van kontaminasie. Identifikasie van spesies kan verkeerd wees indien Genbank gebruik is, omdat die informasie daar nie altyd korrek is nie. Molekulêre tegnieke, alhoewel ‘n goeie manier om spesies te identifiseer, moet gekombineer word met morfologiese karakter eienskappe om akurate resultate te verseker.

Thesis (MBA (Business Management))--University of Stellenbosch, 2009. / ENGLISH ABSTRACT: The Western Cape Education Department (WCED) is responsible for the provision of education to nearly a million learners in 2007/08 from grade R to grade 12. To fulfil its primary function, it employs thousands of educators and officials. Like any organisation, the WCED should be managed effectively to ensure that this main educational mission is carried out. Communication forms an integral part of this management process. This research report focuses on communication processes between two groups within the WCED, namely, officials at Head Office and officials working directly in the Educational Management and Development Centres (EMDCs). The aim was to determine the perceptions that the officials have about communication in the WCED and to make recommendations to the WCED to improve the situation, should such recommendations be needed. Chapter 1 gives a background of the organisation where the research was conducted. Chapter 2 focuses on the literature and gives a review of the different communication theories while applying these to the organisation being researched. Chapter 3 provides an explanation of the method of research and refers to the two groups that are compared, the questionnaire that was developed and administered as well as an explanation of how the statements were analysed. Chapter 4 categorises the responses of the two groups and each statement is analysed based on whether the groups agree or disagree with each other. Summaries of the findings, in four groupings, are presented. Chapter 5 places the focus on the conclusions that have been drawn from the analyses and makes recommendations to the WCED regarding how to improve communication. Several findings were made. There are a number of aspects that officials from both groups agree with, but also many issues that they disagree on. The main finding of the research is that both groups perceive the management of the WCED to be autocratic and that this seems to be one main root of problems related to communication in the department. / AFRIKAANSE OPSOMMING: Die Wes-Kaap Onderwysdepartement is verantwoordelik vir die voorsiening van opvoeding vir duisende leerders vanaf graad R to graad 12. Terwyl dit die primere funksie van die onderwysdepartment is, moet dit ook in gedagte gehou word dat dit duisende onderwysers en amptenare in diens het. Die Wes-Kaap Onderwysdepartement moet effektief bestuur word om te verseker dat die hoofdoel bereik word. Kommunikasie vorm 'n integrale deel van die bestuursproses. Die navorsingsverslag fokus op die kommunikasieprosesse tussen twee groepe binne die Wes-Kaap Onderwysdepartement, naamlik Hoofkantoor- en Distriksamptenare. Die doel was om die persepsies wat hierdie amptenare oor kommunikasie het, te bepaal, en om aanbevelings te maak aan die onderwysdepartment om die situasie wat bestaan, te verbeter. Hoofstuk 1 gee 'n agtergrond van die organisasie waar die navorsing gedoen was. Hoofstuk 2 fokus op die literatuur en gee 'n oorsig van die verskillende kommunikasieteoriee, terwyl hierdie toegepas word op die organisasie wat nagevors word. Hoofstuk 3 voorsien 'n verduideliking van die metodiek van navorsing en verwys na die twee groepe wat vergelyk word, die vraelys wat ontwikkel en geadministeer was, sowel as 'n verduideliking van hoe die stellings geanaliseer sal word. Hoofstuk 4 kategoriseer die terugvoering van die twee groepe en elke stelling word geanaliseer, gebaseer op of die groepe met mekaar saamstem of nie. Hoofstuk 5 plaas die fokus op die gevolgtrekkings wat gemaak word van die analise, terwyl daar ook aanbevelings aan die Wes-Kaap Onderwysdepartement gemaak word oor hoe om kommunikasie te verbeter. In die analise van die terugvoering van die amptenare wat op die vraelys gereageer het, word 'n aantal bevindinge gemaak. Daar is 'n aantal aspekte waaroor amptenare van beide groepe saamstem, maar ook aspekte waaroor hulle nie met mekaar saamstem nie. Die hoof bevinding van hierdie navorsing is dat amptenare die persepsie het dat die bestuur van die WKOD outokraties is en dat dit die oorsaak is van die probleme wat verband hou met kommunikasie in die departement.

Thesis (MSc)--Stellenbosch University, 2015. / ENGLISH ABSTRACT: Invasive arthropod predators are one of the largest and most diverse groups of invasive insects in the world. Many are generalist predators, with cosmopolitan distributions due to their use as biological control agents in agriculture. Harmonia axyridis (Coleoptera: Coccinellidae), an invasive arthropod predator species native to Asia, which now has a world-wide distribution. It is considered one of the most successful biological control predator species and is generally considered to be economically beneficial. However, negative effects have recently emerged in agricultural and natural systems. Harmonia axyridis poses a threat to biodiversity as it outcompetes native species for food resources. It can also feed directly on native predatory arthropods that disrupt natural ecosystem processes. Their movement in-and-out of agricultural landscapes may depend on food availability with natural vegetation alongside agricultural areas often utilised for refuge and alternative food resources. This beetle has also been recorded in urban areas. The aim of this study was to determine how the invasive H. axyridis beetle uses the local landscape in the Western Cape province, South Africa, and to determine its threat to native species. I sampled urban landscapes, vineyards, natural vegetation/vineyard edge zones and pristine natural areas for arthropods every second month using a suction sampler. Data collected included the abundance and diversity of H. axyridis, herbivores, local predators and non-Harmonia ladybeetles. Most H. axyridis were collected in urban areas during all sampling periods. Highest abundance was recorded in May and July (winter). This indicates that urban areas were the preferred landscape feature and that these act as ovipositing areas, particularly as larval H. axyridis were also only collected in urban areas. Significantly, vineyards and natural vegetation had very low abundance of H. axyridis, questioning their value as a biological control agent in this region. Harmonia axyridis had a negative effect on the overall local arthropod community, as well as the predator and herbivore guilds, although it was positively correlated with the abundance of non-Harmonia ladybeetles. This suggests that H. axyridis and non-Harmonia ladybeetles are responding to the same resources in these landscapes. A negative correlation found between H. axyridis and the abundance of predators is most likely due to competition for the same resources (e.g. prey items). These negative impacts, along with their negligible value as biological control agents in agriculture, suggest that a programme should be implemented to control this invasive species. More specifically, control should be aimed in urban areas during winter when and where the species aggregates and when larvae are present. / AFRIKAANSE OPSOMMING: Geleedpotige roofdiere is een van die grootste en mees diverse groepe van uitheemse insekte in die wêreld. Die meeste is veelsydige roofdiere, met wêreldwye verspreiding te danke aan hul gebruik as biologiese beheer agente in landbou gebiede. Byvoorbeeld, Harmonia axyridis (Coleoptera: Coccinellidae), 'n indringer geleedpotige roofdier spesies inheems aan Asië, het nou 'n wêreldwye verspreiding. Dit word beskou as die mees suksesvolle roofdier spesies wat gebruik word vir biologiese beheer en word oor die algemeen beskou as ekonomies voordelig. Negatiewe effekte was onlangs aangeteken beide in landbou gebiede en natuurlike areas. Harmonia axyridis hou 'n bedreiging in vir inheemse biodiversiteit as dit inheemse spesies uitkompeteer vir voedsel bronne. Dit kan ook direk voed op plaaslike roofsugtige geleedpotiges wat trofiese vlakke ontwrig en uiteindelik, biodiversiteit. Hulle beweging in-en-uit landbou landskappe kan gekoppel word aan die beskikbaarheid van voedsel, en gebruik natuurlike plantegroei langs landbou gebiede dikwels as 'n toevlugs oord en area vir alternatiewe voedsel bronne. Harmonia axyridis word ook in stedelike gebiede aangeteken. Die doel van hierdie studie was om te bepaal hoe die indringer Harlekynkewer die plaaslike landskap gebruik met die fokus op wingerde in die Wes-Kaap provinsie van Suid-Afrika, en tweedens om die bedreiging wat hierdie kewer moontlik vir inheemse spesies te bepaal. Ek het arthropoda in stedelike landskappe, wingerde, natuurlike plantegroei / wingerd rand sones en ongerepte natuurlike areas elke twee maande met behulp van 'n D-vac versamel. Monsters was ontleed deur gebruik te maak van die getalle van H. axyridis, herbivore, plaaslike roofdiere en nie-Harmonia liewenheers kewers. Die meeste H. axyridis was in stedelike gebiede versamel gedurende al die seisoene, maar meeste individue was gedurende Mei en Julie (winter) versamel. Hierdie toon dat stedelike gebiede die voorkeur-landskappe is vir hierdie kewers en dat hierdie gebiede opgetree as eierleggende gebiede, veral omdat larwes van H. axyridis slegs in hierdie gebiede aangeteken was. Wingerde en die natuurlike plantegroei het baie lae getalle H. axyridis gehuisves wat hul waarde as biobeheermiddel bevraagteken. Harmonia axyridis het 'n negatiewe uitwerking op die algehele plaaslike geleedpotige gemeenskappe gehad, asook op die die roofdier en herbivoor gildes, maar hul getalle was positief gekorreleer met die getalle van nie-Harmonia liewenheerskewers. Dit dui daarop dat H. axyridis en nie-Harmonia liewenheerskewers beide reageer op dieselfde hulpbronne in hierdie landskappe. 'n Negatiewe korrelasie was gevind tussen die getalle van H. axyridis en die getalle van ander predatoriese geleedpotiges at waarskynlik te danke was aan mededinging tussen hierdie groepe vir dieselfde hulpbronne (bv prooi). Hierdie negatiewe invloede, asook hul verminderde waarde as biobeheeragente in die landbou, dui daarop dat 'n program in werking gestel moet word om hierdie indringerspesies te beheer. Meer spesifiek, beheer moet gedurende die winter en in stedelike gebiede geskied, waar en wanneer hierdie spesie op sy volopste is en waar larwes teenwoordig is.

Local Economic Development (LED) is one of the primary building blocks in terms of the economic growth and development equation for the Province. The primary challenges LED has the potential to address include the following: Job creation, the building of an enabling environment that will encourage economic engagement by a larger number of local entrepreneurs, drawing together a number of critical partners and mobilising their energies and resources towards local economic growth and development, facilitating access to finance, markets, capacity building and business support services, creating the environment which will effect economic viability of local communities and their Local Authorities, linking local product development to provincial, national and international markets. There are many other fundamental challenges. The key issue though is whether people in their communities, especially rural and peripheral environments, are benefiting in real terms regarding the quality of their lives. The LED programme will also give effect to the “Growth, Employment and Redistribution: A Macro Economic Strategy” framework that outlines the strategy for rebuilding and restructuring the South African economy. The document confirms Government’s commitment: “It is Government’s conviction that we have to mobilise all our energy in a new burst of economic activity. This will need to break current constraints and catapult the economy to higher levels of growth, development and employment needed to provide a better life for all South Africans.” (1996:2)

Thesis submitted in fulfilment of the requirements for the degree Magister Technologiae in Information Technology in the Faculty of Informatics and Design 2006 / The primary objective of this research project was to determine whether search engine optimisation elements as specified in the Chambers model, affect real estate website visibility. In South Africa, real estate companies predominantly function as SMMEs and are therefore as vulnerable to failure as any other SMME in the country. In order for SMMEs to reduce the possibility of failure, they need to re-evaluate their use of the Internet, as it could assist in their survival. The traditional company structure is no longer sufficient to ensure market reward. The reality is that users are rapidly adapting to the technology available. The Internet is fast becoming a communication, commerce and marketing medium that is changing business globally. Real estate SMMEs are unable to adapt to e-commerce in its purest form, however, they can make effective use of e-marketing. Static websites are used for that specific purpose. A marketing strategy is imperative to the survival of a company, whereby the firm is able to create and maintain a competitive advantage in a cluttered marketplace. Regrettably, hosting a website on the Internet is not enough. Searchers tend not to view search results beyond the second page - 30 results at the most. It becomes evident that companies should ensure that their own website ranks as high as possible on the search engine result page. This in turn should sufficiently market the company. Search engine optimisation involves designing or modifying websites in order to improve search engine result page ranking. The elements as specified in the Chambers model are extensively elaborated on in the literature analysis. The methodology consisted of two stages - a questionnaire and empirical experiments. A quantitative research approach was adopted for both of these components. The primary objective of the questionnaire was to obtain search phrases from the public when searching for real estate online. The search phrases were then used in the experiments, testing the visibility of predetermined websites, which were based on a pre- post- test control group design methodology. In this instance, the before group consisted of five different websites from five different real estate companies which have been hosted on the Internet for a duration of no less than three months. The Chambers model was used in the development of five new optimised websites, one for each company. The new websites were hosted on the Internet for 27 days, in order to give search engines the opportunity to index them. The results documented were then compared in order to draw a conclusion. A total of 121 key search phrases were obtained. The results from the old and new websites were applied to a process which produced a combination of results known as the ‘quality factor’. The quality factor indicated either a visibility improvement or visibility deterioration with regard to the old and new company’s website. In addition to this, this author compared the optimised website which obtained the best visibility improvement with the website that obtained the highest deterioration in visibility. As a result, the elements specified in the Chambers model were re-evaluated whereby new elements that had not been specified in the original model were identified. Based on the new findings, this author developed a new search engine optimisation model as a secondary objective in this thesis.
