Evaluation of medicinal turpentine used for the prevention of bovine babesiosis in southern KwaZulu-Natal and the eastern Free State

Biggs, L.J. (Louise Joanne) 24 May 2012 (has links)
Medicinal turpentine has been used extensively in the eastern Free State and KwaZulu-Natal in the belief that it is able to prevent and treat redwater in cattle. A number of commercial beef farmers have been using it for many years and the information has been passed down through generations. Redwater is often a fatal disease in cattle and results in losses of large numbers every year in South Africa. In this study redwater is used to describe both Babesia bigemina (African redwater) and Babesia bovis (Asiatic redwater). Redwater is also known as babesiosis. Medicinal turpentine is obtained by the distillation of resin obtained from numerous pine tree species as a by-product during the production of chemical wood pulp9,72. The use of turpentine for the treatment of redwater is, however, yet to be scientifically validated. This study was initiated in an attempt to investigate the validity in the use of the turpentine as a medicinal agent. For this study the use of turpentine was evaluated in three parts. The first component of the study involved a detailed survey with ten commercial farmers from KwaZulu-Natal and the eastern Free State who were known to be proponents for the use of turpentine. The second part of the study made use of a screening assay of Babesia caballi in a red cell culture which was exposed to various concentrations of turpentine in comparison to Diminazene and Imidocarb. Both of these drugs are used on a large scale in the conventional treatment of redwater and are at this point in time the most effective treatments available in South Africa. In the third part a tolerance study was undertaken. Twenty four cattle were treated with turpentine. Three different volumes were used and a control group was treated with saline. Blood was then drawn from these animals at specified intervals and pre-determined parameters were measured. These included obtaining serum for Babesia bovis and Babesia bigemina serology to determine whether the animals used had ever been exposed to either one of these parasites. Temperatures, weights, pregnancy status and injection site reactions were also monitored. From the information gathered farmers are using turpentine in a fairly consistent manner so it was relatively straight forward to design a treatment protocol for the tolerance study that could be representative of what was being done in the field. The cultures indicated that turpentine may have a delayed static effect on parasite growth or it may have an indirectly cidal effect. This effect was most obvious at certain concentrations. It was not seen with all the concentrations used in the cultures. The tolerance study revealed that a significant effect was seen in the protein levels and no deleterious effects were noted either in liver or kidney function. Further studies will need to be undertaken to determine the exact effect turpentine has on the immune response and whether this response is in fact adequate to protect animals from redwater. AFRIKAANS : Die gebruik van medisinale terpentyn is ekstensief in KwaZulu-Natal en die oos Vrystaat gebruik vir die voorkoming van beide Afrika en Asiatiese rooiwaterstamme. Hierdie gebruik is reeds geslagte lank vir die behandeling en voorkoming van rooiwater deur boere gebruik. Rooiwater is n toenemende probleem vir kommersiële boere en daar kom jaarliks groot veeverliese voor. Medisinale terpentyn is die byproduk van sekere denneboomspesies. Die harpuis verkry tydens die vervaardiging van houtpulp met die Kraftproses, word gedistilleer9,72. Tydens die ondersoek na die gebruik van terpentyn deur sekere boere is eerstens tien boere van KwaZulu-Natal en die oos Vrystaat betrek. ‘n Vraelys is opgestel waarin die betrokke boere oor die gebruik van terpentyn gevra is. Tweedens is kulture van Babesia caballi in die laboratorium gekweek en met verskillende konsentrasies van terpentyn behandel. Diminazene en Imidocarb is as die positiewe kontroles gebruik. Beide hierdie produkte word op groot skaal met sukses deur boere gebruik om beide rooiwaterspesies te bestry. Huidiglik is dit die mees effektiewe behandeling van rooiwater in Suid Afrika. Derdens is die verdraagsaamheidstudie onderneem en vier en twintig beeste is in die proef gebruik. Terpentyn is teen drie verskillende konsentrasies gebruik. Die kontrole groep is met soutwater behandel. Bloed is met verskillende intervalle van die beeste getrek en vooraf bepaalde parameters is vir meting gebruik. Dié oefening het ingesluit die verkryging van serum om te bepaal of die diere voorheen blootgestel was aan enige van die rooiwaterspesies. Temperatuur, gewigte, dragtigheidstatus en reaksie op die inspuitplekke is gemonitor. Die gegewens ingewin by die boere wat terpentyn gebruik, was voor die handliggend om toleransie daarvan in die praktyk te bepaal. Die kweking van die parasiete dui daarop dat verskillende konsentrasies van terpentyn die groei daarvan vertraag en moontlik vernietig. Hierdie effek is nie by al die konsentrasies waargeneem nie. Die toleransie studie het aan die lig gebring dat dit ‘n effek op die proteïenvlakke gehad het maar geen newe-effekte op die lewer en nierfunksie gehad het nie. Verdere studies sal onderneem moet word om te bepaal watter effek terpentyn op die immuunstelsel het en of dit genoegsaam is om diere teen rooiwater te beskerm.

The impact of east coast fever on African homestead society in the Natal colony 1901-1910

Thabede, Mfanimpela Ishmael 08 1900 (has links)
This dissertation looks at the impact of East Coast Fever on African homestead society in Natal in the period 1901-1910. The disease broke out in Natal at the beginning of 1904. With the realization that East Coast Fever was another lethal epizootic, the Natal Colonial Government introduced measures to control the spread of the disease and finally eradicate it. The campaign was, however, not successful. The disease thus spread throughout the colony and led to the loss of many cattle owned by Africans. By 1909 not more than four divisions in the colony remained free of the disease. The death of many cattle deprived Africans of the means of extensive cultivation, the source of income for the payment of rents and taxes, and Ilobolo. Many African males were forced to leave their homesteads for the towns and the mining sector in search of work. This eventually changed the nature of the homestead society. / History / M.A. (History)

Teachers’ experiences of change : a case study analysis of a school-based intervention in rural Kwazulu-Natal

James, Sally Jane January 2014 (has links)
The research presented in this thesis is a case study analysis of the school-based intervention initiated by the David Rattray Foundation [DRF]. David Rattray, a South African historian well known for his contribution to the 1879-1896 Anglo-Zulu War heritage, was murdered in January 2007. In response to his untimely death, the DRF was established by family and friends with the hope of improving education within the Umzinyathi rural municipal district of KwaZulu-Natal. This study consisted of three phases: Phase I (May-December 2011); Phase II (January-December 2012), and Phase III (December 2012-October 2013). During Phase I, the focus was on describing the broader context in which the case is located. It resulted in a narrative account of the emergence of the DRF as a non-governmental organisation [NGO] working towards change within the local rural school community. During Phase II the focus shifted from the broader socio-political and economic context to the human dimension which included teachers, principals, volunteer workers and a district official working in the schools. During Phase II the approach to change adopted by the DRF was critically analysed in relation to models of change described in the literature. Teachers’ experiences of change were also examined. Phase III was a synthesis of the findings from the first two research phases. By drawing on systems and complexity theory perspectives, insights were gained enabling a deep understanding of the DRF’s school-based intervention as a whole. This research is a qualitative study that seeks to understand individual teachers’ experiences and participation in a process of change that reaches beyond the individual and his/her immediate context. The adoption of a realist ontology (Maxwell, 2012) and application of an explanatory heuristic based on the critical realist philosophy of Bhaskar (1979, 1980, 2011) enabled the layered analysis and in-depth interpretation that characterises the study. The findings of the study reveal a complex and ongoing process of change within a rural school context. The results illuminate the efficacy of a collaborative partnership between civil society (the DRF), the local community, under the leadership of a tribal authority, and the local government (KwaZulu-Natal Provincial Department of Education). It also reveals how teachers within this particular context do not have a strong voice in the change process and hence participate only superficially in the school-based intervention. It is probable that the constraining mechanisms revealed through this research are not exclusive to this particular case study, but are common across the South African rural school context. The main contention of this thesis is that these mechanisms need further interrogation in order to enable further change and permit the active participation of teachers in the process.While the study illuminates many of the tensions and problems faced by the schools and the community in which they are located, it also highlights the achievements and selfless attitude of many people working towards change and improvement within the schools. This case study thus provides an example to all South Africans of what can be achieved with commitment and effort.

A critical evaluation of local level responses to mine closure in the Northwestern KwaZulu-Natal coal belt region, South Africa

Buthelezi, Mbekezeli Simphiwe January 2004 (has links)
The de-industrialisation process that was a common feature of North America and Western Europe in the 1970s, through into the 1980s has become an observable feature in African countries and South Africa in particular in the last two decades. Globally, hard hit areas include those associated with the early Industrial Revolution characterised by mass production and the agglomeration of iron and steel, coal and textile industries. General changes in the global market, especially the falling demand for extractive heavy minerals like coal and gold have also affected many countries region and localities. In the case of South Mrica, the previous high economic dependence on mined minerals like coal and gold has resulted in many once prosperous mining regions of the country being reduced to a shadow of their former selves. The worst affected areas in South Africa are those of the Klerksdorp Goldfields in the North West Province and Free State Goldfields, with the latter alone losing 100,000 jobs during the 1990s. This trend has also been acute in the coal-mining industry of the KwaZulu-Natal province since the late 1970s. The firms that had grown in the shadow of the major mining company supplyipg machinery, or who processed the semi-manufactured product are also severely affected by the closing down and restructuring in the mining and iron industries. These industries have often been forced to close down because of a break in the vital connections they developed with these mining industries. Such localised economic crisis has encouraged the universal trend towards the devolution of developmental responsibilities to the local governments and other local stakeholders to - empower them to respond to these changes. This study investigated the local economic initiatives which have been undertaken in the three municipalities of north-western KwaZulu Natal i.e. Utrecht, Dundee and Dannhauser to respond to the closures which have taken place in the mining industry of this region, which used to be among the most prosperous coal mining regions of South Africa. Using their new developmental mandate the local governments, in partnership with the communities and other external interveners have tried to respond to these localised economic crisis and also indirectly to the general poverty and underdevelopment, which characterises this region of KwaZulu-Natal. The effects of apartheid policies, and previous discriminatory rural development policies in, particular, and the Regional Industrial Development policy, which was intensively applied in the 1980s by the pre-1994 government regime, have further compounded the magnitude of the challenge. The lack of capacity in some municipalities has constrained successful implementation of Local Economic Development has led to some communities acting alone to face their situation with or without external intervention.

The simultaneous acquisition of a second and third language

Bruce, Marian Elsie 11 1900 (has links)
This study investigates whether it is possible and necessary to acquire a second and third language simultaneously in our present multicultural, multilingual South Africa with its eleven official languages. The qualitative, descriptive empirical research was executed for the duration of the first school term within a multiracial grade four class at Richmond Primary School in KwaZulu Natal. Afrikaans and Zulu were taught in separate periods, simultaneously, for the exact number oflessons per week, with the exact same content, method and teacher. The success ofthe research, rested on maintaining absolute reality within the normal daily routine of the school day, in order to see if it is possible to acquire two languages simultaneously. The very positive outcomes of this research cannot be generalized, but rather indicate possible tendencies that it is indeed possible to acquire two languages simultaneously. / Psychology of Education / M.

An assessment of the implementation of the Service Delivery Improvement Policy in the Department of Arts, Culture and Tourism in KZN

Mnculwane, Vikinduku Victor 03 1900 (has links)
Thesis (MPA (School of Public Management and Planning))--University of Stellenbosch, 2009. / As an attempt to usher in a paradigm shift in the way public services are rendered in the new dispensation, Section 195 of the Constitution of the Republic of South Africa, Act No. 108 0f 1996, envisages a Public Administration governed by specific values and principles intended to act as a guide in government‟s endeavours of seeking to provide services impartially, fairly and without bias. According to the supreme law of the country, this could be achieved among other things by responding adequately to the needs of the people and further entrenching the participation of the citizenry in the policy processes of government; thus deepening good governance. Part of the challenge that faces the realization of what the Constitution envisages centres largely around the transformation of public servants sothat they begin to deliver services in a way that puts the citizen first. To this extent government has already responded with a very ambitious Batho Pele program, the implementation of which is intended to effect a turn around in the Public Administration status quo bequeathed by the past, so that it is deliberately focused on the needs of the client. The current section of the thesis is an introduction to the entire work aimed at assessing the levels of implementation of the Service Delivery Improvement Policy of Provincial Government within the Department of Arts Culture and Tourism in KZN.

Mabaso, Thandeka Grace 03 1900 (has links)
Thesis (MPhil)--Stellenbosch University, 2005. / ENGLISH ABSTRACT: This paper was written with the intention of investigating how Knowledge Management (KM) influences an organization's competitive advantage. The objective of the research questions was to determine KM's role in a competitive advantage. Knowledge is the critical asset of any organization whether profit or nonprofit. This paper will discuss the meaning of the competitive advantage focusing attention in a non-profit organization, which will serve as a framework for subsequent argument and the remainder of the study. Research into KM's relation with business issues such as leadership, IT for KM, organizational structure was conducted. The objective was to determine the readiness of the institution in implementing Knowledge Management as a basis for its competitive advantage and also to determine the role of the leadership for KM and IT for KM and to propose a new agenda for the Chief Knowledge Officer. This paper is organized around six chapters. It begins with introduction and background chapters where the research question, research setting and KM's competitive advantage are discussed. An in-depth literature review follows in chapter two. Chapter three deals with the detailed description of the methodology followed to compile this paper. A data report and analysis in chapters four and five followed by recommendations for rolling out of KM initiative are considered. Research concludes in chapter six. / AFRIKAANSE OPSOMMING: Hierdie studiestuk is geskryf met die bedoeling om die wyse waarop Kennisbestuur (KB) 'n organisasie se mededingende voordeel beïnvloed, te ondersoek. Die oogmerk van die navorsingsvrae was om KB se rol met betrekking tot mededingende voordeel te bepaal. Kennis is 'n belangrike bate vir enige organisasie met of sonder winsbejag. In hierdie stuk word die betekenis van mededingende voordeel bespreek met die klem op 'n organisasie sonder winsbejag wat as raamwerk sal dien vir daaropvolgende argumente en die res van die studie. Navorsing is oor die verband tussen KB en sake-aangeleenthede soos leierskap, inligtingstegnologie (IT) en organisatoriese struktuur gedoen. Die oogmerk was om die gereedheid van die instelling te bepaal vir die implementering van KB as 'n grondslag vir sy mededingende voordeel en ook om die rol van leierskap vir KB en IT vir KB vas te stel en om 'n nuwe agenda vir die Hoof Kennisbeampte voor te stel. Hierdie stuk bestaan uit ses hoofstukke. Dit begin met 'n inleiding en 'n hoofstuk met agtergrondinligting waar die navorsingsvrae, navorsingsomgewing en KB se mededingende voordeel bespreek word. 'n Deeglike literatuur-oorsig volg in hoofstuk twee. Hoofstuk drie handel oor 'n gedetailleerde beskrywing van die metodologie wat gevolg is om hierdie stuk te lewer. 'n Dataverslag en -ontleding word in hoofstukke vier en vyf oorweeg, gevolg deur aanbevelings vir die uitrol van 'n KB inisiatief. Die navorsingsgevolgtrekking is in hoofstuk ses vervat.
