- Description: After the 1994 general elections, the government realised the importance of efficient and effective financial management and public sector procurement for the rebuilding of South Africa. This was done by embarking on a major review of its financial and supply chain management systems. The financial and supply chain management systems operate in an ever-changing environment, and that requires that these systems are fit for purpose. Supply Chain Management is one of the cornerstones for the performance of any organisation or company. Section 217 (3) of the Constitution of the Republic of South Africa requires organs of state irrespective of whether they are at National, Provincial or Local government level to apply a procurement system which is fair, equitable, transparent, competitive and cost-effective when contracting for goods and services. The Constitution also attempts to protect and advance persons disadvantaged by unfair discrimination. Supply Chain Management has met an ever-increasing interest over the past decade. This interest comes from within the industry due to the huge amounts involved in procurement and the supply chain value creation. Every society strives to be in a state where every need is available and every citizen has what he/she requires to be able to leave a fulfilled life. In order to meet the needs of societies, member of the society carry out economic activities. The public procurement practice and systems have been acclaimed, based on empirical evidence, as the best means of guaranteeing the provision of public goods to the Citizens and public expenditure management.

- Description: Tax avoidance by multinational enterprises is the focus of much media and political scrutiny. It is also the subject of a major Organisation for Economic Co-operation and Development (OECD) project called Base Erosion and Profit Shifting (BEPS). The objective of this thesis was to gain a greater understanding of BEPS, particularly in a South African and Australian context, and to determine whether BEPS is as great a problem as the OECD portrays. A detailed analysis of the OECD BEPS Report and Action Plan was undertaken to understand what the term BEPS means. A review of current BEPS literature was then performed toassess the extent of BEPS. This was followed by a comparative analysis of South Africa and Australia, including a comparison of their tax systems and various economic indicators. It was found that there is no simple definition of BEPS. It encompasses the spectrum of international tax planning strategies used by multinational enterprises. Furthermore, these tax strategies are usually legal, which makes measuring the extent of BEPS conceptually difficult. Despite being legal, many observers believe that BEPS behaviour by multinational enterprises is ethically unacceptable. This thesis also discussed the ethics of tax avoidance, and argued that countries should assess BEPS with reference to the many benefits which multinationals bring to a country. The benefits of multinational enterprise activity are especially important to developing countries like South Africa. Despite similar tax systems, South Africa and Australia vary greatly in terms of their economic and social position. This thesis concluded that South Africa, as a developing country, is more likely than Australia to tolerate BEPS behaviour in order to maintain or even attract foreign investment. The OECD Action Plan calls for urgent internationally coordinated actions against BEPS. It appears, however, that much more research is needed on the nature and extent of BEPS before countries formulate their response. This thesis acknowledges that aggressive tax planning by multinational enterprises does exist, but suggests that countries approach BEPS, and any estimates of its extent, with a degree of caution.

- Description: The study sought to inquire about the youth’s knowledge and understanding of diabetes in relation to its different types with regards to determined societal components such as education, culture, healthcare and socioeconomic status. It then became important to establish what the youth in Humewood, Port Elizabeth, understand about diabetes in relation to its three different types with regard to education, culture, healthcare and socioeconomic status in Humewood, Port Elizabeth. Previous studies have failed to inquire about knowledge construction and understanding of diabetes in Port Elizabeth, this provided an opportunity to do so, especially since diabetes is growing rapidly and is a lifelong illness. Most studies tend to focus on disseminating information to those that already have diabetes, overlooking the importance of diabetes education as a preventative strategy. The research followed a qualitative approach which included semi-structured individual face-to-face interviews as a method of data collection amongst ten participants using convenience sampling. The data revealed the importance of diabetes education and representation, and showed that financial standing and healthcare are interconnected. Complex inferiorities and social stratification hinder the betterment of the general welfare and therefore signifying social injustice. This research is an important contribution to medical anthropology in the context of Port Elizabeth, South Africa.

- Description: Summary: A recording spectrometer for the measurement of fluorescence excitation spectra in the visible and ultra-violet regions of the spectrum is described. A direct method of modulating the hydrogen light source of the spectrograph is presented, whereby the discharge is driven by an A.C. power oscillator. The use of tuned amplifiers in the detecting unit is investigated as a means of eliminating the D.C. component of the dark current. Aspects of the modulation method are discussed. Fluorescence and energy transfer in aromatic hydrocarbon is discussed with particular regard to anthracene. Some absorption, fluorescence, excitation and reflection spectra of anthracene obtained by previous workers are presented9 together with Tables listing the wavelengths of principal maxima for the above spectra published in the literature. Features of the excitation spectrum of anthracene are discussed and are related to its absorption and fluorescence spectra. The role of surface effects, defects and impurities are discussed in relation to the fluorescence of anthracene. The method of A.C. detection was unable to resolve the excitation spectrum of anthracene due to the high noise level associated with the method. However, peaks in the ultra-violet region of the hydrogen molecular spectrum were recorded at a modulation frequency of 400 Kc/sec. The noise level is explained and ways of improving the signal to noise ratio of the A.C. detection system are suggested. It is concluded that D.C. detection is a simpler and more direct way of measuring excitation spectra. No modulated signals were detected when the hydrogen discharge was excited at 6·5 Mc/sec. Signals were recorded at modulation frequencies of 400 Kc/sec . The degree of modulation at 400 Kc/sec. increased with decrease in the pressure of the hydrogen discharge.

- Description: South Africa occupies a unique space in terms of the decolonization of the continent of Africa. While massive projects of decolonization where happening across the continent, South Africa was subjected to a conservative and racialised project of segregation. This arrested development makes for an interesting anachronism in South Africa as disconcerting “ThirdWorld” and “First-World” economies emerged creating an anomalous temporality. I was born just a month before the inimitable Ruth First was unceremoniously assassinated in Mozambique in 1982. While further South, one of the most underreported conflicts of apartheid South Africa was in its nascent stages no further than a kilometer away from my house. I am referring of course to the violent clashes between factions of both the Inkatha Freedom Party (IFP) and the African National Congress (ANC), played in the men’s hostel of the third largest township in the country, Umlazi, South of Durban. These would only come to have meaning to me later, when I was at university. I mention these cultural and perhaps socio-political artefacts in so far as they relate to the kind of environment that lead to this research enquiry. Which is to say that as social beings, we are in fact products of the things that affect the social environment that we exist in. This is not a new idea. What is particularly interesting for this enquiry is the eclecticism of the emblems that survive to shapes one’s own identity and perception of the world around them. Within the above stated mini-biography lies a complex matrix of emotions and extrapolated meanings mediated through a conflicted and negotiated understanding of what the social history of South Africa meant for my own personal history. This paper is an attempt to think through articulations of time as they are constituted by future-orientated subjectivities extending back to varied pasts. It does so by exploring a recent work of black South African self-writing, Jacob Dlamini’s Native Nostalgia (2009). Considering the text’s treatment of time, I argue that porous conceptions of temporality open up possibilities for self-enunciation. What Paul Gilroy has described as “the signs of sameness” (2000, 101). Meaning that these could be quantified and as such researchable and in fact applied across various cultural texts (including but not limited to film). The body of work from South African documentary filmmaker Rehad Desai provides an interesting case study to examine Jacob Dlamini’s thematic pre-occupations with nostalgia. Nostalgia here is used to see if such pre-occupations can be applied to a filmic body of work. Desai’s body of work is interesting to this enquiry because it almost exclusively deals with the temporalities of South Africa as “refracted through the prism of the past”. By this I mean Desai through his work appears to reflect on South Africa’s storied past as it affects current happenings. It is the intention of this paper to argue that Desai deals with his subject (the evolution of the South African political landscape) in similar terms to the way Jacob Dlamini explores the notion of reflective nostalgia.

Equity employees are those employees jescribed as such in the Employment Equity Act 55 of(1998). Bussin's (2002) Total Rewards Model was used as the theoretical framework for the study. The investigation was conducted within an interpretive paradigm and employed a qualitative methodology. Thematic analysis was used in the interpretation of the three data sources gained access through the data collection process. A previously completed employee relationship audit's findings, and the data derived from nine exit interviews formed the basis for the twenty-four semi-structured individual interviews, which were conducted with a sample ofthe employees. A purposive sampling technique enabled the identification of particular employees, who were the equity participants in the study. An additional component of the Total Rewards Model, namely Talent Management was identified from an analysis of the results. Six salient factors were highlighted in the investigation. The factors identified were: A need for a short-term incentive plan, which would provide recognition above and beyond an employee's monthly salary. The need for career development opportunities. The utilization of new skills from the training initiated by the organization. The representation of women and Black people in senior management positions. The need for formal performance support. The standardization of the recruitment process, the management of unrealistic or unattainable expectations and listening to employees' concerns. , KMBT_363 , Adobe Acrobat 9.54 Paper Capture Plug-in

- Description: Eastern Cape is one of the provinces experiencing a rapid increase in food prices while household income is increasing at a slower rate. Against this background, the main objective of this study was to investigate strategies used by rural households to improve food security in Raymond Mhlaba Local Municipality formally known as Nkonkobe in the Eastern Cape Province, South Africa. Data were collected from 100 households using a questionnaire as the main instrument by using simple random sampling. Data were analyzed by employing simple descriptive statistics to describe household food security. Results revealed that most (50.3percent) households that were interviewed were male headed and unemployment was high (73.6percent). Moreover, the average age of the interviewed household heads was 59 years. Most (68percent) of the households owned home gardens and had access to arable land which was not being cultivated. Most (87percent) households indicated that lack of capital was the main cause of food security and depended on government grants. Most (100percent) of the interviewed household heads depend mostly on food purchases rather than their own production. The recommendation is that the government should continue fostering its agenda of improving agriculture as a strategy in rural households for curbing food insecurity.

- Description: This study seeks to examine economic activity using anthropological perspective at Lower Gqumahashe. This settlement possesses natural resources that favour agricultural development. For instance, water resources include Tyhume River, which is the main source of irrigation. Tyhume Rive is the perennial river that runs along the study area. Other possible sources of irrigation are local livestock dams and the main water pipe supplying University of Fort Hare and Alice town. This study is an attempt to determine the impact of formal education on agricultural productivity at Lower Gqumahashe. The study population was female local farmers who were actively involved in agricultural activities during the course of investigation. The researcher used empirical research design. The researcher realized that empirical research design would offer her an opportunity for intense or prolonged contact with research informants in order to have a holistic picture of their behavior. The findings of the study reveal that low level of formal education of farmers impacts negatively on agricultural productivity in the study area. The study recommends that local female farmers should be encouraged to participate in adult basic education using incentives.

- Description: Participative management, a key theme in contemporary management literature, is one of the central aims of the decentralization policy in Namibian education. Current perceptions of participative management on the part of teachers in Namibia are therefore of topical interest. This study set out to explore such perceptions among teachers in a Namibian primary school. The study is an interpretive case study focusing on six individual teachers’ understanding and experience of participative management within their place of work, a primary school in the Oshikoto region of Namibia. Semi-structured interviews, observation and document analysis were used to gather data. The study revealed a strong sense of commitment among the respondents to participative management and its accompanying practices, such as shared decision making and broad stakeholder involvement. Participative management was implemented chiefly through a committee structure for school organisation and government. Respondents also highlighted challenges facing participative management, such as the persistence of autocratic leadership, conflicts of interest in decision making, laziness and unwillingness among staff members, and a lack of understanding among parents concerning their role in the schooling of their children. HIV/AIDS was also seen to pose challenges to the free and frequent participation of stakeholders. The chief recommendation arising from these findings is that school leaders and managers’ understanding of tenets of participative management, such as site-based management and democratic management approaches, requires improvement and development.

- Description: Reisbeskrywings, en veral die reispoësie as genre, het met die aanbreek van die twintigste eeu „n opbloei binne die Afrikaanse letterkunde beleef. Talle Afrikaanse skrywers en digters het na verskillende kontinente gereis en hul ondervindinge in roman, dagboek of joernaalvorm aangeteken. Die Afrikaanse skrywers sluit hulself gevolglik aan by die tradisie van die reisbeskrywing wat reeds eeue lank deel vorm van die globale literêre kanon. Reispoësie kom veral voor in die werk van digters soos C. Louis Leipoldt, Uys Krige, W.E.G. Louw, N.P. van Wyk Louw, D.J. Opperman, Breyten Breytenbach, Lina Spies, Petra Muller, Joan Hambidge en meer onlangs Melt Myburgh. Dit is veral Hambidge wat oor reis in haar poësie skryf. In 2011 verskyn „n versameling van Hambidge se reisgedigte wat sedert 1985-2010 in van haar bundels verskyn het onder die titel Visums by verstek – ‘n Keur uit die reisgedigte van Joan Hambidge. Hambidge bespreek sekere deurlopende temas in haar gedigte. Die temas sluit in: die poësie en die verhouding tussen die liefde en die poësie, die mens as alleenreisiger deur die wêreld, die dood en die huldiging van gestorwenes asook die beskrywing van sekere gebeurtenisse in die wêreldgeskiedenis. In hierdie skripsie word gefokus op die ontleding van Hambidge se reisgedigte wat onder drie verwante temas bespreek word naamlik die stad as vreemde rumite, reis as metafoor vir ontvlugting van die geliefde en reis as kreatiewe stimulus. Hierdie ondersoek geskied aan die hand van onder meer Pratt se konsep van “kontaksones”. Reispoësie word binne die konteks van globalisasie as „n belangrike bron van inligting en inspirasie beskou aangesien dit tot „n nuwe geslag wêreldreisigers spreek wat opnuut die literêre waarde van die reisbeskrywing- en poësie ontdek het.

- Description: Acid mine drainage is of growing concern for both developing and developed economies. Thus there is increasing pressure to develop alternative remediation strategies. Biological sulphidogenic mechanisms have long since been studied but, very few have been implemented on a large scale. Limitations are due to the inability to acquire a suitable, low cost, environmentally friendly, renewable carbon source. The present study investigated the use of an algae biomass generated by the HRAOP of an IAPS as a carbon source for the EBRU 00AB/06 SRB consortium. The algae biomass and consortium were utilized together to remediate simulated AMD. Remediation involved decreasing the sulphate and metal concentrations in solution and decreasing the acidity of a simulated AMD. Experiments were carried out to investigate the capability of the EBRU 00AB/06 SRB consortium for sulphate reduction and sulphide generation. The consortium produced colonies when grown under anaerobic conditions in Petri dishes containing modified lactate SRB medium. The SRB consortium reduced the sulphate concentration of modified Postgates medium B and generated sulphide. Further analysis of the EBRU 00AB/06 SRB consortium revealed that the consortium was minimally impacted at pH 5 and by sulphate and iron at 3 g.L-1 and 0.5 g.L-1 respectively. The EBRU 00AB/06 SRB consortium was exposed to Actinomycin D and Ethidium Bromide to determine whether transcription and translation of proteins was required for sulphate reduction. Results indicated that sulphide generation and sulphate reduction were inducible. Analysis of the algae biomass used in this study revealed the empirical formula C1.0H1.91N0.084S0.003O0.36 indicating a carbon source rich in the nutrients required to sustain microbial development. Light microscopy revealed that algae cell walls and in particular those of Pediastrum were susceptible to acid hydrolysis. Dinitrosalicylic acid, Nile red, Bradford and Ninhydrin assays were used to determine the reducing sugar, lipid, protein and amino acid content respectively, of the mixed algae biomass. Results showed that upon exposure of the biomass to simulated AMD at pH 1 and pH 3, the concentration of reducing sugars and amino acids in solution increased. Whereas levels of lipids remained unchanged while the protein concentration decreased, indicating that, upon exposure of algae biomass to AMD, simulated or otherwise, cells ruptured, proteins were hydrolyzed and polysaccharides were broken down to sugars which are immediately available for SRB utilization. Exposure of biomass to simulated AMD revealed further that the presence of algae biomass increased the pH of simulated AMD (pH 3) to pH 7.67 after 4 d. Likewise, the pH of simulated AMD at 1 increased to 1.77 after 2 d while pH of the neutral control increased to 8.1 after 4 d. A direct comparison between lactate and algae biomass revealed 94 % sulphate removal after 23 d in the presence of algae biomass while 82 % sulphate removal was measured in the presence of lactate. Thus the EBRU 00AB/06 SRB consortium successfully utilized algae biomass for sulphate reduction and sulphide generation. In another experiment to establish if the consortium could remediate simulated AMD (pH 5) containing 0.5 g.L-1 iron and 3 g.L-1 sulphate while utilizing an algae biomass as the carbon source no residual iron was detected after 14 d and by day 23, an 89.07 % reduction in sulphate was measured. The results of this investigation are discussed in terms of utilizing a readily available and renewable biomass in the form of microalgae produced in HRAOPs as an effective carbon source in the SRB catalysed remediation of AMD.

- Description: This study investigated psychological capital (PsyCap) as a mediator of the relationship between workplace conflict (WC) and organisational citizenship behaviour (OCB). The study was based on equity theory as well as the social exchange theory. The sample encompassed of 151 administrative staff members from the University of Fort Hare (Alice, Bhisho and East London campuses) in the Eastern Cape Province. Argentero, Cortese, and Ferretti (2008) organisational citizenship behaviour questionnaire was employed to assess OCB; the Interpersonal Conflict at Work Scale (ICAWS) was employed to assess workplace conflict; and Luthans, Avolio, Avey, and Norman’s (2007) psychological capital questionnaire by McGee (2011) was employed to assess psychological capital. In terms of data analysis, a descriptive analysis, correlational analysis together with simple linear regression analysis and multiple linear regression models were applied using the Statistical Package for Social Sciences (SPSS) version 25. The findings indicated a negative relationship between workplace conflict and organisational citizenship behaviour. Thus, for the purpose of enhancing extra-role behaviours amongst staff members, the management of the institution needs to ensure equitable compensation, rewards, and benefits amongst workers. This is vital because should the employees perceive that inequity exists, they will fight for fairness and justice, and if they are not heard, it will result in workplace conflict.

- Description: Thermoluminescence of synthetic quartz annealed at 1000 ºC for 10 minutes has been studied. The aim was to study mechanisms of thermoluminescence in annealed synthetic quartz and to discuss the results in terms of the physics of point defects. The sample was irradiated with a beta dose of 10 Gy of beta radiation and then heated at a linear heating rate of 1 ºC.s-1 up to 500 ºC. The thermoluminescence (TL) glow curve consists of three glow peaks. Peak I at 74 0C (main peak) with high intensity as compared to the other two peaks. Peak II at 144 ºC is more intense than peak III at 180 ºC. This study was on the main peak (MP) at 74 ºC and peak III at 180 ºC. Kinetic analysis was carried out to determine the trap depth E, frequency factor s and the order of kinetics b of both peaks using the initial rise, peak shape, variable heating rate, glow curve deconvolution and isothermal TL methods. The values of kinetic parameters obtained were around 0.7 to 1.0 eV for trap depth and in the interval of 108 to 1015 s-¹ for frequency factor for both peaks. The effect of heating rate from 0.5 to 5 ºC.s-¹ on the TL peak intensity and peak temperature was observed. Also the effect of thermal quenching was observed at high heating rates. Since the TL glow curve has overlapping TL peaks, the Tm-Tstop method from 54 ºC up to 64 ºC and E -Tstop methods were introduced where a first order single peak was observed. Phototransfered thermoluminescence (PTTL) was investigated and characterized by three peaks. First PTTL peak I at 72 ºC, peak II at 134 ºC and peak III at 176 ºC. Analysis was carried out on peaks I and III for the effect of dose dependence from 20-200 Gy. Thermal fading was observed on PTTL peaks I and III, after storage time of 30 minutes.

- Description: Climate variability affects rural households and agricultural productivity, yet it is just one of many stresses that vulnerable rural households have to cope with. Climate variability is not as noticeable as weather variability, because it happens over seasons and years. It is the manner in which climate fluctuates above or below a long-term average value. Without measures at local and national level to adapt to climate variability, risk of food insecurity will continue to increase at household level. The objective of the study was to determine factors affecting adaptation to climate variability. Purposive sampling was used to identify households who participated because of un-availability of sampling frame. Information was elicited from the selected households with the aid of a semi-structured questionnaire. The study utilised a cross-sectional survey of 205 farming households in Tyhume Valley communities. Data gathered was subjected to descriptive statistics, Cross tabulations and Binary logit model. The results indicate that rural households from Tyhume Valley communities practiced coping adaptation through use of the following adaptation strategies; crop rotation, planted drought resistant crops, changed planting dates and used indigenous strategies such as using ash to kill mule (intuku). Most of the households used irrigation as the coping strategy to adapt to climate variability. However, heatwave, high winds, employment status, cell phones, age and gender of the rural households’ heads have effects on households’ adaptation to climate variability in Tyhume Valley. In view of the research findings, a large number of farming households are old and are females, there is a need for development of labour saving technologies and extension services to increase the likelihood of adaptation of climate variability by vulnerable farmers such as women and elderly farmers.The study also recommends that there must be a development of infrastructure for farmers as they are negatively affect by high winds due to low infrastructural development.The study also shows that farming households who have access to cellphones are more likely to adapt to climate variability, therefore the study recommends that communication of farming households must be improved.Adapting to climate variability is an increasingly important issue in agriculture and one that is likely to persist for many years.

- Description: The stories in this collection explore the fantastical, the power of memory, and the human capacity to love. Moving between the surreal, the absurd, the allegorical, and the metafictional, they elaborate on life's ordinary madness and the mysteries of the spirit. By challenging the either/or boundaries of the binary of realism and fantasy, the stories provoke the reader to engage actively with the text. Influenced by experimental US author Stacey Levine, the mid‐century British novelist Barbara Comyns, and the adventurous Chinese writer Can Xue, in most cases, they create a playful, experimental world that exists at a slight angle to the world as we know it.

The holy spirit in the theology of St. Luke

- Description: The essay consists of five main chapters with an introduction and conclusion. This defines the limits of the essay and explains the methodology employed. These chapters are examined particularly with reference to the Spirit as the agent of fulfillment of the old, and the inaugurator of the new. 'The main text examined is Lk. 1.35. The Spirit is shown to be also used in a skillful linking and differentiation of John the Baptist and Jesus. Through a fairly detailed synoptic comparison, the peculiarly Lukan emphasis is brought to light. The Baptism is linked with 1.35 and the Transfiguration. Again both the Baptism and Temptation are shown to be seen in the light of the fulfillment of the Old Covenant. All the lines of fulfilment join together in the Spirit's descent on Jesus. The immediate result of this is the testing of his Messiahship, and Proclamation in the synagogue of Nazareth. This proclamation is coupled with the Luken rejection motif. The Spirit is seen to be especially involved in Jesus' ministries of exorcism and healing, but also in his preaching and teaching. The position of Lk 4.18-19 is seen to be of great importance. The main problem is the lack of specific reference to the Spirit. This is resolved in similar fashion to the question of the Messianic Secret. The relation of the apostles to the spirit is also discussed, since this is relevant to the ministry of the Church. Firstly the relation between the Transfiguration and Ascension is examined. This points to the fundamental centrality of the Ascension in Luke's theology. Pentecost is then seen as the fulfilling of the Ascension in the Church. Secondly, as a minor theme, the resurrection appearances are looked into and the similarities with Johannine thought are noted. This raises the question of the historicity of the Lukan schematization. In the examination of Pentecost itself the problem of the quotation from Joel and also the relation of Pentecost to the founding of the Church and the Gentile mission are raised. The Spirit is revealed to be active in two main areas : (1) the mission of the Church in evangelization - this is especialy seen in the areas of preaching, miracles and the life of the Church ; (2) the establishing and justification of the Gentile mission - this overriding concern is shown to obscure the other functions of the Spirit especially in the realm of Baptism and the Christian life of the individual. Thus Luke's historical sense is seen to be coupled with a theological desire to justify and bolster the Gentile mission. This draws out the various conclusions within the essay. The question of 'salvation-history' is raised and a solution found in terms of Luke's use of the Spirit. In broad outline the schema of Conzelmann is accepted. The Lukan eschatology is mentioned in an attempt to find a solution to questions raised by the comparison of Luke with Paul and John. This comparison is only meant to place the main conclusions of the essay within the context of the wider New Testament.
