AFRIKAANSE OPSOMMING: Die eerste gedeelte van hierdie tesis is ʼn opstel met die titel Van plaas tot agterplaas: Die uitbeelding van Afrikaners in Johannesburg in drie Hertzogpryswenners en die tweede deel is ʼn roman getiteld ʼn Duisend stories oor Johannesburg. Die roman en die opstel hou tematies met mekaar verband. Soos die roman, speel al drie bekroonde werke in Johannesburg af met Afrikaners as sentrale karakters. Die bepaalde historiese konteks waarin elkeen van die drie pryswenners verskyn het, dikteer die invalshoek van die opstel, hoe die werk krities ontvang is, sowel as die rol en waarde wat deur die Afrikaner-instelling daaraan toegeken is. Daar sal verder in die bespreking getoon word watter rol die Hertzogprys in die skepping van die Afrikaner-instelling gespeel het. Die gebruik van die begrip en eienaam “Afrikaner” in hierdie bespreking verwys na die wit, Afrikaanssprekende, Christelike gemeenskap in Suid-Afrika, in die sin dat dit ooreenstem met die (uiters aanvegbare) stelling dat alle wit Afrikaanssprekers saamgevoeg kan word in ʼn organiese “volkseenheid”. Hierdie voorveronderstelling aanvaar ook dat hierdie “Afrikanerdom” tradisionele, konserwatiewe volkswaardes deel, en altyd beskikbaar is vir mobilisering ter wille van gedeelde Afrikaner-belange, soos deur Dan O‟Meara gedefinieer in sy Volkskapitalisme: Class, capital and ideology in the development of Afrikaner nationalism, 1934 – 1948 (1983:6). Hierdie kwessies word, onder meer, deur die polisisteemteorie van die Israeliese kultuurnavorser, Itamar Even-Zohar, asook J.B. Thompson se kritiese teorie van ideologie gedoen. Daar word ook na Jacques Rancière se teorie oor “die verspreiding van die waarneembare” (the distribution of the sensible) verwys. Daar word tot die gevolgtrekking gekom dat die Hertzogprys van meet af aan in diens van die Afrikaner-instelling gestaan het en ten spyte van ʼn veranderende ideologiese landskap, ʼn voortgesette rol gespeel het in die daarstelling van die Afrikaner-repertoire. Binne die polisisteemteorie is die “repertoire” die versameling reëls en elemente wat die produksie van tekste bepaal. Die term “instelling” verwys na die faktore wat betrokke is by die instandhouding van die letterkunde as ʼn sosio-kulturele aktiwiteit. Die roman speel af in ʼn klein Johannesburgse hotelletjie, genaamd Mei Villa, in die buurt Belgravia, tydens ʼn uitbarsting van xenofobiese geweld in 2008. Binne ʼn raamverhaalstruktuur fokus die roman op twee karakters, naamlik die ontheemde argitek, Zweig van Niekerk, wat na 40 jaar na Johannesburg terugkeer, asook die hoteleienaar, die bekroonde maar mindere digter, Bosman Hiemstra. Omring deur hotelgaste en personeel met hulle uiteenlopende verhale, soek Zweig van Niekerk tevergeefs na die Johannesburg van sy jeug, terwyl Bosman Hiemstra met ewe min sukses ʼn tweede digbundel probeer skryf. Aan die einde van die boek begin die digter ʼn roman te skryf met sy gas se lewensverhaal as gegewe dalk ook die boek wat die leser pas klaar gelees het.
ENGLISH ABSTRACT: The first part of this thesis is an essay titled Van plaas tot agterplaas: Die uitbeelding van Afrikaners in Johannesburg in drie Hertzogpryswenners (From farm yard to back yard: The depiction of Afrikaners in Johannesburg in three Hertzog Prize winners) and the second part is a novel called ʼn Duisend stories oor Johannesburg (A thousand tales of Johannesburg). The novel and the essay are thematically linked. Like the novel, the three Hertzog Prize winners takes place in Johannesburg with Afrikaners as central characters. The point of departure of the essay is the historical context in which the three literary works were published, the critical reception thereof and what role and value was attributed to it by the Afrikaner institution. The role played by the Hertzog Prize in the creation of the Afrikaner institution will also be discussed. The term “Afrikaner” in this discussion refers to the white Afrikaans-speaking, Christian community in South Africa, in the sense that it correlates with the (highly debatable) contention that all white Afrikaans-speakers can be combined in an organic “volkseenheid”. This use of the term assumes that “Afrikanerdom” also shares traditional, conservative national values, and is always available for mobilisation in service of shared Afrikaner interests, as defined by Dan O'Meara in his Volkskapitalisme: Class, capital and ideology in the development of Afrikaner nationalism, 1934 – 1948 (1983:6). To examine these issues, the polysystem theory of the Israeli cultural researcher, Itamar Even-Zohar, as well as J.B. Thompson's critical theory of ideology, will be used. Reference is also made to Jacques Rancière's theory around “the distribution of the sensible”. The conclusion is reached that despite a continuously changing ideological landscape, the Hertzog Prize served the interests of the Afrikaner institution from the very start and played an ongoing role in the Afrikaner repertoire. Within the polysystem theory the “repertoire” is the aggregate of rules and elements which determine the production of texts. The term “institution” refers to the factors involved in the maintenance of literature as a socio-cultural activity. The novel is set in a small hotel, Mei Villa, in the Belgravia neighbourhood in Johannesburg during an outbreak of xenophobic violence in 2008. Within the story structure it focuses on two characters, the displaced architect, Zweig van Niekerk, who returns to Johannesburg after 40 years, and the hotel owner and award-winning, but lesser poet, Bosman Hiemstra. Surrounded by other hotel guests and staff with their own stories, Zweig van Niekerk searches in vain for the Johannesburg of his youth, while Bosman Hiemstra attempts with equal lack of success, to write a second book of poetry. At the end of the book the poet starts to write a novel using his guest's life as material; that could be the book that the reader has just completed.

Thesis (MScAgric (Conservation Ecology and Entomology)--University of Stellenbosch, 2005.
A semi-arid country, like South Africa, with unpredictable seasonal rainfall, is subject to great scarcity in water and an ever-increasing demand from the rising human population. Therefore, efficient reservoirs as well as monitoring methods are needed to manage the South African water supply. This study was undertaken on the Eerste River in the Western Cape, South Africa, focusing on the impact of the Klein Plaas dam system on the benthic macroinvertebrates. The study also examined the use of benthic macroinvertebrates as bioindicators of water quality with special reference to the South African Scoring System Version 5(SASS5) that is currently being used nationally. The impoundment of the water, as well as the inter-basin transfer programme and the experimental cage-culture trout farm, all play a significant role in the disturbance impact of the dam on the Eerste River system. The disturbance is manifested as a drop in water quality that can be seen in the distribution of keystone species, changes in the riparian vegetation, as well as in physical-, chemical-, and biomonitoring evaluations. The study also indicated that the SASS5 is effective, but needs some adjustments, such as inclusion of a prediction phase, finer spatial-scale methodologies and greater consideration of the rarity of species.

Scholarly communication has changed with the growth in technology, particularly the internet and the social web. The changes include a broader definition of the scholarly communication format, and the role of social media in the research process, amongst others. This study sought to record the body of work that PLAAS had produced over a 20-year period (1995 to 2015) and to measure its visibility and impact through bibliometrics and altmetrics. It was the first time that such a study had been done. The Web of Science Citation Index and Scopus are two commercial databases that have recently been joined by Google Scholar, the first open database of scholarly items with citation counts based on the entire contents of the World Wide Web. Scopus and Google Scholar were used in this study. Methods used in the study included the compilation of a full bibliographic record of the outputs during that period. Citation analysis and publication counts were conducted, per author, within Scopus and Google Scholar. Altmetric analysis was achieved with the Altmetric Explorer database, and by studying three PLAAS grey literature outputs in more depth for altmetric indicators. The last method used was a small survey based on an online multiple-choice questionnaire of researchers at PLAAS to investigate their attitudes to a selection of the social media platforms commonly used by scholars. The full list of outputs, once compiled, showed a composition of 54% grey literature published by PLAAS and 46% journal articles and monographs. The results showed that bibliometrics, as a purely quantitative indicator, can be useful in measuring the impact of a body of work on the scholarly domain and in this study indicated high publication and citation rates. The authors of the highest number of PLAAS outputs and with the highest citation counts and h-indices, were found to be the same throughout the study. These authors are closely associated with the Institute and have contributed to the good academic reputation of its research. The study was inconclusive with regard to the impact on social media platforms as none of the grey literature from PLAAS had a unique identifier which made it difficult to track; in addition, the use of social media by the Institute and its researchers was intermittent and uneven in covering all the PLAAS-published outputs that were produced. Key recommendations for PLAAS to improve the visibility and impact of their outputs in scholarly and social contexts were to use unique identifiers, to track their social media activity and to keep author profiles up to date. Further use and application of the research design in other research units and departments at UWC will generate results that are useful to research management at UWC.

The vitamin D metabolite 1,25-dihydroxyvitamin D3 [1α,25(OH)2D3] plays an important role in the regulation of musculoskeletal growth and differentiation. 1α,25(OH)2D3 mediates its effects on cells, including chondrocytes and osteoblasts, through the classical nuclear 1α,25(OH)2D3 receptor. Additionally, recent evidence indicates that several cellular responses to 1α,25(OH)2D3 are mediated via a rapid, calcium-dependent membrane-mediated pathway. These actions of 1α,25(OH)2D3 can be blocked by antibodies to protein-disulfide isomerase family A, member 3 (Pdia3), indicating that it is part of the receptor complex; however, the pathway which is activated by this receptor is not fully understood. The overall goal of this thesis was to examine the roles of phospholipase A2 activating protein (PLAA) and calcium calmodulin-dependent kinase II (CaMKII) in 1α,25(OH)2D3 rapid membrane-mediated signaling. We further investigated the interaction between two pathways regulating growth plate cartilage and endochondral bone formation, 1α,25(OH)2D3 and Wnt5a, at the receptor complex level. Results indicated that PLAA was required for mediating 1α,25(OH)2D3 signal from Pdia3. Furthermore, CaM and CaMKII were identified as mediators of 1α,25(OH)2D3-stimulated PLAA-dependent activation of cPLA2 and PKCα, and downstream biological effects. Wnt5a and 1α,25(OH)2D3 are important regulators of endochondral bone formation. This study demonstrated that 1α,25(OH)2D3 and Wnt5a mediate their effects via similar receptor components in osteoblasts and chondrocytes suggesting that these pathways may interact.

Abstract Since 1990 the development of world wide armament towards C4ISR system by the Revolution of Military Affairs-RMA, and the related technologies of Electronic Warfare-EW system has become the core engineer for supremacy of military power. As so called a “Rising Great Country”, the construction of Chinese military armament is following the western experience to create “military reform with Chinese character” for the goal of military modernization, and the development of EW system which represents the achievement of total readiness of the People`s Liberation Army. According to the Chinese developing of aerospace technologies in the recently years, their efforts to build an integrated environment for aerospace readiness, therefore, the reason of historic background, development of theory and utility in each phases has being a subject for research item which either underlining the trend of PLAAF or observation of how the combination with air and magnetic power by the PLA.

Since PRC has established, its military thought throughout take "people''s war" as highest guiding principle. In 1991, the USAAF has carried out the high tech air strike on Iraq. It makes PLA understand they have been unable to adapt the future war condition request. Therefore the PRC adjusts its strategic concept, change "people''s war" principle to "wins the modern technology war", especially "under high-tech condition local war". The PRC thought the characteristic of future war will be limited the battlefield for the war goal. Therefore the local war emphasize to the rapid attack, the total recall is useless. But the air force is suitable for this kind of war. Although the PLAAF positively imitates the USAAF`s tactic, the weak of researching and developing the weapon let the PLAAF still learning the ability of carried out the high-tech war. By the China economic potentiality is formidable day after day, its ability of carries out the high-tech air strike even could not achieve in the short time, but it will happen in the near future.

According to the clear and definite air force strategy, PLAAF devotes itself to modernization supporting the national interests and military strategy. Purchasing and converting of SU-27/SU-30 is the significant mission for promoting the capability to cope with hi-tech local war. Due to the complex and extensive scope of the mission involved, it’s difficult to find out the real key problem and resolution. However, supposing some meaningful outcome can be acquired, it should be helpful to further deduce the trend of PLAAF’s development. Looking into a specific case and draw the reasonable inference is a new model in such kind of research. If this mode was practicable, it was feasible for other similar academic thesis.

When the SARS broke out between March and April 2004, China’s fight against the disease revealed several socio-economic problems such as the imbalance of social welfare business and economic development, wrongdoing of policies and the ever-enlarging gap between city and rural areas. After the SARS, Chinese government realized the importance of impartial development of society VS.economy, city VS. rural areas and human VS. nature. As a result, in October 2003, Chinese president Hu Jintao raised so-called Scientific Development Concept, to insist establishing a comprehensive,coordinated and sustainable development concept based on humanity, so as to facilitate the comprehensive advancement of socio-economy and human society. The PLA sees the Scientific Development Concept as a guidance that could help it adopt to the variation of China’s security environment, strike a balance between defense buildup and economic development, as well as proceed with military construction at a unprecedented speed and efficiency. As China integrates the Scientific Development Concept into its defense buildup and military construction, highlights the importance of a harmonious relationship between defense and economic construction, and insists on a coordinated development between defense and economic construction, it is aiming at establishing a modern military power based on the continuous development of national economy, which goes along with the long-term interest of its national security and development. Its goal is to achieve a wealthy society and a strong military at the same time. The PLAAF’s measures on personnel education, political propaganda, military training and logistic construction from 2005 to 2009 reveals that it is heading towards the goal of modern construction to establish a strategic air force that can effectively carry out new historic mandates. Judging from the PLAAF’s related constructions from 2005 to 2009, we can see that under the instruction of the Scientific Development Concept, the PLAAF has strengthened its personnel education, paid more attention to the protection of soldier’s basic rights, endeavored to form the air force culture, and highlighted the importance of military training and logistic modernization.

Abstract Over the years, the People’s Liberation Army Air Force has made remarkable progress in its modernization. This essay attempts to get hold of the really military strength, advantage, disadvantage and obstacles. The purposes of this research are: 1) to know the clear picture of the PLAAF modernization so as to predict its future development, 2) to evaluate its impact on the security of the Asia Pacific region, 3) to provide a reference to the military situation is South China Sea, 4) to map out a plan for our military development and defense policy in the future. To deal with the potential conflicts in the South China Sea, countries concerned have started shopping spree of advanced sea and air weapon systems so as to maintain their military and political status. When most Western countries were trying to cut down their defense spending during the Post Cold War Period, the East Asia was the region where military investment and acquisition were greatly increasing. These countries were aiming at gaining the upper hand by their power supremacy over the issue of South China Sea sovereignty. In fact, the targets for armament expansion for these countries are procuring high performance aircraft, missiles and combat vessels, hoping to take control of the marine exploration and close isles to increase their influences in the region. According to the Military Strategic Missions for the New Period”, the PLAAF will adjust its strategy from “Air Defence” to active “Simultaneous Offensive and Defensive Operations”, implying that the PLAAF is fostering air combat power to meet the requirement for future wars. The PLAAF is earnestly engaging in phasing old equipments, developing the fo4th Generation fighters F 20, intimidating weapons and long range combat capabilities, whose purpose is to counter the surprise military attack from hegemonism countries. The PLAAF intends to take preemptive strikes to gain air superiority over the air space of the conflict region. For the current situation in the South China Sea, the PLAAF with current Tong Fong 5 missiles, F 10, F 11 and Su 30 fighters after its military modernization will be strong enough to deter Vietnam and the Philippine air power and maintain air superiority over the South China Sea. Key words: Modernization, Military Strategic Missions for the New Period, Air Defence Type, Simultaneous Offensive and Defensive Type

Hierdie studie ondersoek vrae rondom die aard van literêre niefiksie - ook die vierde genre genoem. Die bestaande drieledige genreklassifikasiesisteem maak nie voldoende voorsiening vir tekste waarin die grense tussen feit en fiksie opgehef word nie. Die toename van sodanige hibriede tekste noodsaak dus ‘n uitbreiding van tradisionele genrekategorieë tot ‘n vierde, naamlik dié van literêre niefiksie. Dié ondersoek poog om vrae rondom literêre niefiksie te beantwoord met verwysing na De plaag: het stille knagen van schrijvers, termieten en Zuid-Afrika (2001) van David van Reybrouck. Dié teks dokumenteer Van Reybrouck se ondersoek na die bewering dat Maurice Maeterlinck die termietnavorsing van Eugène Marais sonder erkenning oorgeneem het. Tydens sy navorsingsreis maak Van Reybrouck kennis met die verwikkeldhede van ‘n postapartheid Suid-Afrika en verwoord sy reiservaring met behulp van metafore uit die entomologie. Die resultaat is dat De plaag ‘n hibriede karakter vertoon wat versoenbaar is met die kriteria vir literêr-niefiksionele tekste.
This study attempts to explore the nature of literary nonfiction (the fourth genre). The existing tripartite classification system does not make adequate provision for texts where the borders between nonfiction and fiction are transcended. A marked increase in such texts therefore necessitates an expansion of the traditional genre categories to accommodate a fourth, namely that of literary nonfiction. De plaag: het stille knagen van schrijvers, termieten en Zuid-Afrika (2001) by David van Reybrouck will serve as point of departure to explore the genre of literary nonfiction. The said text documents Van Reybrouck’s investigation into the alleged plagiarism by Maeterlinck of Marais’ research on termites. Van Reybrouck’s travels expose him to the complexities of a post-apartheid South Africa, which he expresses by using metaphors derived from the field of entomology. The result of this process is that De plaag displays a hybrid character which complies with the criteria for literary nonfiction.

Hierdie histories-argeologiese studie bied ‘n basiese beskrywing van die materiële kultuur van ‘n afgeleë Suider-Afrikaanse plaas wat tussen die 1880’s en die 1930’s bewoon is. Die studie berus op ‘n gedetailleerde ontleding van die opgegraafde vondste wat herwin is van ashope wat met drie wooneenhede op die plaas Welkomskraal, geleë in die distrik Venterstad in die Noordoos-Kaap, verbind word. Die artefakte is aan die hand van die naslaanversameling in die Bloemfonteinse Nasionale Museum en handelsadvertensies geïdentifiseer. Die materiële kultuur dek die volle spektrum van die alledaagse lewe van die plaasbewoners en word aangevul deur genealogiese data, wat aantoon dat die grondeienaars die nasate was van die eerste trekboere wat hulle in die gebied gevestig het. Die bewoningsperiode van Welkomskraal val saam met die tweede industriële revolusie, wat gekenmerk is deur die massaproduksie van goedere en ‘n toenemend globale handelsnetwerk. Die versameling lewer bewys dat boere in die verre binneland toegang tot ‘n wye reeks ingevoerde produkte gehad het, hoewel hulle nie noodwendig welvarend was nie.
This historical archaeological study provides a baseline description of the material culture of a remote southern African farm occupied between the 1880s and the 1930s. The study is based on a detailed analysis of the excavated finds recovered from middens associated with three homesteads, located on the farm Welkomskraal, in the Venterstad district of the north-eastern Cape. Artefacts were identified using the reference collection of the National Museum in Bloemfontein and commercial adverts. The material culture covers the full spectrum of the daily lives of the farm’s occupants and is complemented by genealogical data, which indicate that the landowners were the descendants of the first trekboers who settled in the area. The occupation of Welkomskraal coincided with the second industrial revolution, which was characterised by mass production of goods and an increasingly global trade network. The assemblage attests that farmers in the deep interior had access to a wide range of imported goods although they were not necessarily prosperous.

The People's Republic of China is developing a sophisticated Anti-Access/Area-Denial operational concept utilising a variety of defensive military capabilities, entwined with offensive components. The United States, Japan and other Asia-Pacific countries remain sceptical about China's defensive rationale for developing this operational concept because it threatens to undermine Asia-Pacific security. Specifically, the threat posed by China's military modernisation to the security of Japan may force the Japanese Government to adopt a more self-reliant defence posture. However, there are a variety of factors that complicate Japan's perception of China and restrict the number of feasible response options open to the Japanese Government. As such, this sub-thesis will examine the nature of China's Anti-Access/Area-Denial operational concept in addition to the factors complicating Japan's response and finally the ways that Japan may respond to the rising power of China.

2015 Chinas Military Strategy indicated that In line with the strategic requirement of mobile operations and multi-dimensional offense and defense, the PLA Army (PLAA) will continue to reorient from theater defense to trans-theater mobility. In the process of building small, multifunctional and modular units, the PLAA will adapt itself to tasks in different regions, develop the capacity of its combat forces for different purposes. After Xi Jin Ping’s Military Reform PLAGF operation institution are specifically contained in that the four military general departments had been changed into 15 CMC military offices, seven military regions had been changed into five theater commands and the general command of the army established. Above institutional change made PLAGF operation institution form flat organization, multifunctional operations and trans-theater mobility. In other words, PLAGF operation institution after Xi Jin Ping’s military reform has far-reaching implications and deserves our close attention. This study analyzes PLAGF operation institution after Xi Jin Ping’s Military Reform through the "institutional approach". Comparing the differences between the Chinese and U.S. operation institution, analyzes the military exercises of PLAGF and explore operation institution within the framework of rational choice institutionalism. New PLAGF operation institution will prove whether PLAGF can achieve the three goals that is “winning the information war”, “supporting PLAGF strategy” and “strengthening capability of joint operations”. The PLA have completed "above the neck” reform and “below the neck” reform keeps going to develop. Operation institution is positively related to combat forces. From the internal organization structure, the military service, theater command to the strategic level of CMC, operation institution will inevitably produce specific combatforces. However, in the process of adapting the military to the institution, practice and adjustment, whether PLAGF operation institution has been enhanced the combat power during the transformation process or not. This is still a question for researchers.

Paratrichodorus meyeri De Waele & Killian, 1992 is extremely sensitive to surface sterilization; therefore in vitro culture could not be utilized for the mass culture of this nematode and another method had to be developed. Hermetically sealed glass containers were employed successfully for the reproduction of Paratrichodorus meyeri. With this method an average 12 times increase was achieved on tomatoes over a period of 60 days. Certain crops were evaluated in the greenhouse to establish their status as hosts for Paratrichodorus meyeri. The aim of this experiment was to determine which plants could be used as hosts for the reproduction of the nematodes in the greenhouse. It was found that tomatoes (cultivar Roma VF) and wheat (cultivar Gamtoos) were excellent hosts, tobacco (cultivar K51E) and onions (cultivar Bon accord) good hosts, tobacco (cultivar TL 38) and lettuce (cultivar Great Lakes) average hosts and sweetcorn (cultivar Golden Bantam), beetroot (cultivar Formanova) and cabbage (cultivar Sugar Loaf) unsatisfactory hosts for this nematode species. The aim was also to determine the effect of this nematode species on tobacco and cotton. Various inoculation levels of Paratrichodorus meyeri were tested on tobacco cultivars K51E, TL33 and RK and the cotton cultivar Acala 1517170. It was established that an inoculation level as low as 50 - 100ft! Qsoil had a negative effect on cotton (cult. Acala 1517170). A damage threshold value of 100ft! Q soil on the tobacco . cultivar K51E was established. It is also possible for tobacco cultivar RK to support this nematode species without any adverse effects it can even be beneficial for this particular cultlvar. It was also determined that a negative correlation exits between the initial number of nematodes inoculated and the final population.

South Africa is facing an ongoing public health crisis with increasing and alarming human immunodeficiency virus (HIV) statistics. Farmworkers in South Africa are highly vulnerable and susceptible to HIV. This study involved the farmworker community on a farm in the North West province of South Africa. The purpose of this study was to explore the perceptions and acceptance of home-based HIV counselling and testing (HBHCT) in a rural farming community, using an interactive World Café method to stimulate creative discussions around questions that matter. Thirty-one farmworkers participated in the World Café. This study had an explorative approach and qualitative design. The study did not investigate the number of HIV infections or sexual practices on the farm, and did not offer an HIV test or any other medical treatment to any participant. Data were collaboratively analysed by the researchers and the participants. Content analysis of data was conducted. The findings indicated that majority of the farmworkers had a positive perception of HBHCT, and that there was a serious need for HIV prevention and intervention in this community. Some concerns were raised among the participants regarding the confidentiality of HBHCT, attention should therefore be paid to these concerns. More research is needed to establish linkage to care after HBHCT. It remains unclear whether the migrant farmworker population would be effectively linked to HIV care and treatment without legal identification documentation. The acceptance of HBHCT in the farming community by farmers, should be explored. The study found that there would be a high level of acceptability if HBHCT were to be offered to farmworkers in this region. This study created insight into the HIV care and prevention needs of the local farmworker community, as well as highlighted the barriers the farmworkers face in attending primary healthcare (PHCs) clinics for HIV testing.
Suid-Afrika staar ’n voortdurende openbare gesondheidskrisis in die gesig met toenemende en onrusbarende menslike immuungebrekkige virus (MIV)-statistieke. Plaaswerkers in Suid-Afrika is uiters kwesbaar en vatbaar vir MIV. Hierdie studie het die plaaswerkergemeenskap van ’n plaas in die Noordwes-provinsie van Suid-Afrika geteiken. Die doel van hierdie studie was om die sieninge en aanvaardingsvlakke van tuis-gebaseerde MIV-berading en -toetsing (TSMBT) te ondersoek, deur gebruik te maak van die “World Café”-metode om kreatiewe bespreking rondom belangrike vrae te stimuleer. Een-en-dertig plaaswerkers het deelgeneem aan die “World Café”. Hierdie studie het nie die aantal MIV-infeksies of seksuele praktyke op die plaas ondersoek nie, en ook nie ’n MIV toets of enige ander mediese behandeling vir enige deelnemer aangebied nie. Die studie het gevind dat die meerderheid van die plaaswerkers ’n positiewe persepsie van TSMBT gehad het, en dat daar ’n dringende behoefte aan MIV-voorkoming en - ingryping in hierdie gemeenskap is. Bekommernis is uitgespreek deur die deelnemers rakende die konfidensialiteit van TSMBT, dus moet aandag hieraan geskenk word. Die studie het gevind dat daar ’n hoë vlak van aanvaarding van TSMBT sal wees as dit aan die plaaswerkers in hierdie streek gebied word. Hierdie studie skep insig in die MIVsorg- en -voorkomingsbehoeftes van die plaaslike plaaswerkergemeenskap, en beklemtoon die hindernisse vir plaaswerkers om die primêre gesondheidsorgkliniek te besoek vir MIV-toetsing.

Bangama- 31 abasebenzi basepulazini ababambe iqhaza esizindeni sokucobelelana ulwazi (i- World Cafe). Lolucwaningo aluzange luphenye izibalo zabantu abatheleleke ngegciwane lesandulela ngculazi kanye nezinga labo lokuzibandakanya ocansini, futhi aluzange lunike abebebambe iqhaza ithuba lokuhlolela igciwane lesandulela ngculazi(HIV) kanye nokulashwa kwanoma iluphi uhlobo. Imiphumela iveze ukuthi iningi labasebenzi basemapulazini babe nemibono emihle mayelana nosizo lokululekwa nokuhlolela igciwane lesandulela nngculazi (HIV) emakhaya (HBHTC), futhi kunesidingo esikhulu sokuthi kungenelelwe kulomphakathi ukuze kuvikelwe igciwane lesandulela ngculazi (HIV). Kube nokukhathazeka kwababebambe iqhaza mayelana nezimfihlo zokulekelelwa ngokwelulekwa kanye nokuhlolela igciwane lesandulela ngculazi emakhaya(HBHCT),ngalokhoke kufanele kubhekelelwe lokho kukhathazeka. Ucwaningo luveza ukuthi kuzokwamukelwa ukuqala usizo lokwalulekwa nokuhlolela igciwane lesandulela ngculazi (HBHCT) kubasebenzi basemapulazini kulesisifundazwe. Lolucwaningo luveze ngokujulile izidingo zokunakekela kanye nokuvikela igciwane lesandulela ngculazi (HIV) emphakathini wabasebenzi basemapulazini kulendawo, laphinde lwaveza nezithiyo (Barriers) abasebenzi basemapulazini abahlangana nazo mabevakasha emitholampilo (PHCs) ukuyohlola igciwane lesandulela ngculazi.
