- Description: The study focused on the factors influencing the procurement processes in the Supply Chain Management. The empirical part of the study was conducted at the Eastern Cape Provincial Planning and Treasury at Bhisho. The Supply Chain Management (SCM) is the organisation’s identification, acquisition, access, positioning and management of resources in order to attain its objectives. Supply Chain Management System is the South African reform process that the South African Government developed, for sound management of procurement activities within government. Section 195 (1) of the Constitution of South Africa, 1996 (Act 108 of 1996), sets out the basic values and principles governing public administration which include a high standard of professionalism, efficiency, economic and effective use of resources, and promoting transparency at all times. Section 217 (1) of the Constitution further states that when an organ of state contracts for goods and/or services it must do so in accordance with the system which is fair, equitable, transparent, competitive and cost effective. Treasury Regulation 16A.6 on the procurement of goods and services provides that procurement either by way of quotations or through competitive bidding processes must be within the thresholds as determined by the National Treasury, and in the case of procurement through bidding processes, the SCM system must provide for the establishment, composition and functioning of Bid Specification, Evaluation and Adjudication Committees. The departmental processes were measured against the applicable prescripts and the study revealed that the departmental processes were in line with the applicable legislation. Areas of concerns were however raised where the department needs to come up with innovative ways to implement the procurement processes to be economical and also to train the officials involved in procurement.

- Description: Mobile Commerce (MC) can be defined as any transaction carried out over a wireless network, using a wireless device, such as a mobile phone, and that has monetary value (Wang and Liao, 2007). MC is a rapidly developing industry in tenns of its technological capabilities. With these increasing developments, come greater forecasts of potential benefits to societies, economies, industries and individuals. However, the growth and development ofthe underlying MC technology, has not been met by the creation and adoption of the services meant to accompany MC. It is said that the success of MC will ultimately lie in its services. As MC Service Providers (MCSP) are responsible for delivering these MC Services (MCS), the success ofMC can be said to rest on them. In order for MCSs to be successfully adopted, both the initial use and continuous use thereof should be targeted. In other words those that have used MCSs (users) and those that have yet to use MCSs (non-users) should be targeted. It is thus pivotal that an understanding of the factors that generate MCS adoption be sought. This research purposed to uncover the factors that generate MCS adoption within the user and nonuser group. In defining successful adoption ofMCS's, two separate measures were used for each group. User satisfaction is a well accepted construct among researchers for measuring system success among users. User satisfaction is also accepted to be a detenninant of service re-use and loyalty. Intention to use is a measure used for MC success among non-users and is accepted to be a detenninant of actual use. Factors affecting both detenninants, user satisfaction and intention to use, were investigated. After a review ofliterature and current models, ten (10) factors were hypothesised to be significant factors in determining user satisfaction and intention to use namely: ease of use, cost, speed, personalisation, pennission, privacy, security, convenience, relationship (with MCSP) and awareness. A questionnaire was developed to test the hypothesised factors. Not all factors were proven to have a significant impact on both user satisfactions and intention to use. One main recommendation is that both initial and continuous adoption should be the focus ofMC strategy. Services that cater to specific user needs and offer convenience at a low cost should be offered. MCSPs can use the factors proved to be significant to generate and evaluate their service offering, to users and non users, to increase the probability of successful adoption from initial to continuous use. The research concludes that MCSPs need to begin to offer MCSs that meet user needs and add value to their lives in order to realise the professed potential ofMC.

- Description: First of all, South Africa‟s struggle against racial discrimination has received international exposure but the focus now is on gender disenfranchisement which is, however, eclipsed by the struggle for racial redress. In the current climate of redress, post Apartheid South Africa has pledged an unequivocal commitment to the promotion of a unitary, non-sexist, non-racist South Africa in all facets of life. Several enabling national policies have been legislated to promote equity and access to those previously excluded by virtue of race and gender, particularly in assuming leadership roles in key public domains. The catalyst for this study is encapsulated from historical trajectories of women lives, in apparent intractable patriarchal higher echelons, monolithic patriarchal South African school organizations and visible paucity of women in principalship positions of Senior Secondary Schools (SSS) in Dutywa Education District. Significantly, this study actually refers to causality factors of gender imbalance in work places as a provocative factor leading to constant marginalization of women in leadership positions irrespective of sound and clear government policies. This is a principal subject of concern that has grounded this present researcher to undertake this study. Views and ideas applicable in addressing this phenomenon were invited from women teachers of Dutywa Education District and most crucially about the scarcity of women teachers in principalship positions of this District. Questionnaires were distributed to research sites of three sub-districts of concern. The population had been sampled from women teachers of Dutywa Education District, Eastern Cape Province of South Africa. Quantitative results show that organisational factors, culture, women‟s personalities and colonial legacies are obstacles challenging the effectiveness of females in school administration. Specifically, teachers' negative attitudes towards being a female, particularly female principal in schools are cited as the major impediments to women principals of high schools. The study implores governments to continue appointing more women to school leadership positions despite the identified challenges.

- Description: The study investigates factors that contribute to job satisfaction/dissatisfaction in a case study of two Public Senior Secondary Schools as perceived by teachers of Libode District in the Eastern Cape. The point of departure of the study is the fact that the researcher has observed high rate of resignations and transfers of teachers. The study was conducted through a case study design. A total of thirty-five sample subjects from both schools were selected using purposive methods. The instruments used to collect the data were the questionnaires and interviews. The targeted population was teachers teaching in both schools at the area of the research site. Pilot study was done. Ethical issues were taken into consideration. The data collected was, analyzed and interpreted within a specified time frame. The findings were based on the data collected; thereafter the conclusions and recommendations were drawn based on the findings of both the quantitative and qualitative methods. The main findings of the study indicated clearly that poor working conditions, low salaries and ill discipline of learners contribute to job dissatisfaction. Findings were discussed in the context of the main and sub research questions and recommendations were made. The study will help the Department of Education to identify teachers' concern regarding job satisfaction/dissatisfaction.

- Description: Driving a vehicle while it is within the warranty period provide customers with assurance that should a failure occur on the vehicle, there would be no financial obligation for the customer to repair the vehicle. For the manufacturer, it is a huge financial obligation to repair or replace components that fail on the vehicle. The research conducted in this study explores and identifies the main reasons for high warranty costs as well as the reasons that do not influence high warranty costs at VWSA. The purpose of this research is to provide VWSA with a potential starting point to reduce warranty costs and increase profits. The study revealed that the main cause of high warranty costs at VWSA was related to the quality of vehicles. By improving the quality of vehicles produced, VWSA could reduce a significant portion of the warranty costs it spends each year. With reduced warranty costs, VWSA could increase the warranty period and thereby attract more customers to purchase VW products. In a cutthroat automotive industry, this would ensure a competitive advantage over rivals; maintain longevity, increase profits and continued success.

The study has been circuits of the Engcobo district. Questionnaires were administered over a group of matriculants, English second language teachers and 8 school principals with a variety of questions and interviews on the causes of this failure problem. Based on the study it has been reared through collect data that some teachers have not been workshopped in the current curriculum (NCS) and this somehow affects the learners. Learners from rural areas have a problem in understanding English language. Lack of educational facilities like libraries also have a negative impact in learner’s progress. Learners who came from Junior Secondary Schools to High schools are not ready and this gives High School teachers a big task to mould them to be ready for matric. It is recommended that parental involvement is vital in their children’s education so as to see their progress and to develop the teacher-parent locomotives learners need to be engaged in Educational activities like debates, public speaking, conducting so as to improve their communication skills. Educators should give more writing and reading exercises to learners so as to minimize the number of learners who are unable to write in Matric. , Thesis (MMED) -- Faculty of Educational Sciences, 2013

Faecal source tracking and water quality in the Eastern Cape, South Africa

- Description: Water quality is concerning as many still lack access to safe drinking water. Alternate sources such as rivers (FC up to 1600 CFUs/100 mL) and rainwater are often polluted. Rainwater tanks require maintenance to improve water quality, but could be used for non-potable purposes or irrigation. Grahamstown infrastructural failures initiate deviations from DWAF 1996 domestic water guidelines for microorganisms within the distribution system. Frequent testing can decrease risks of waterborne diseases. Limitations to this are inaccessibility of rural areas, distances from testing centres and costs. The low cost H2S strip test able to be used onsite by communities, may aid in risk assessment. H2S strip test results are not affected by sulphate (14 to 4240 mg/L) or nitrite (up to 47 mg/L). Transportation of the H2S strip tests between 10 and 32°C does not modify results significantly. Similarly to other studies: Klebsiella spp.; Enterobacter spp. and Serratia spp. were isolated from H2S strip tests. The mH2S strip test corresponds best with HPC in treated water, while in untreated river water it has approximately 90% correspondence with FCs, while survival of FC causes discrepancies with the H2S test after 22 days. A faecal coliform inactivation rate of 0.1 CFUs/ day, may be longer than many pathogens. Faecal source tracking, not currently practised in South Africa, could aid health risk assessments for disaster management, which would improve the NMMP programme. Bacterial survival times could propose the time period for which water is unsafe. Bifidobacteria and Rhodococcus are proposed to help identify the faecal pollution source. But enumeration of Rhodococcus is too lengthy (21 days). The tracking ratio of bifidobacteria (between 0.1 to 6.25) is not source definitive. The bifidobacteria survival rate, could indicator the time since faecal pollution. The bifidobacteria average survival rate is 2.3 CFUs per day for both groups. The culturability and selectivity of agar is still poor, with total bifidobacteria less selectively culturable. Enterococci overgrowth of TB was decreased by Beerens media. SUB is still useful to identify potential human faecal inputs. A single tracking method is thus not suitable alone, but requires a combination of techniques.

- Description: Malaria is an infectious disease caused by parasites of the Plasmodium genus with mortality rates of more than a million annually, hence a major global public health concern. Plasmodium falciparum (P. falciparum) accounts for over 90% of malaria incidence. Increased resistance to antimalarial drugs by the Plasmodium parasite, coupled with the lack of an effective malaria vaccine necessitates the urgent need for new research avenues to develop novel and more potent antimalarial drugs. This study focused on falcipains, a group of P. falciparum cysteine proteases that belong to the clan CA and papain family C1, that have emerged as potential drug targets due to their involvement in a range of crucial functions in the P. falciparum life cycle. Recently, falcipain-2 has been validated as a drug target but little is known of its Plasmodium orthologs. Currently, there are several falcipain inhibitors that have been identified, most of which are peptide based but none has proceeded to drug development due to associated poor pharmacological profiles and susceptibility to degradation by host cysteine proteases. Non-peptides inhibitors have been shown to be more stable in vivo but limited information exists. In vivo studies on falcipain-2 and falcipain-3 inhibitors have also been complicated by varying outcomes, thus a good understanding of the structural variations of falcipain Plasmodium orthologs at the active site could go a long way to ease in vivo results interpretation and effective inhibitor design. In this study, we use bioinformatics approaches to perform comparative sequence and structural analysis and molecular docking to characterize protein-inhibitor interactions of falcipain homologs at the active site. Known FP-2 and FP-3 small molecule nonpeptide inhibitors were used to identify residue variations and their effect on inhibitor binding. This was done with the aim of screening a collection of selected non-peptide compounds of South African natural origin to identify possible new inhibitor leads. Natural compounds with high binding affinities across all Plasmodium orthologs were identified. These compounds were then used to search the ZINC database for similar compounds which could have better binding affinities across all selected falcipain homologs. Compounds with high binding affinities across all Plasmodium orthologs were found.

- Description: From the Introduction: There has been significant reform of South African legislation pertaining to same-gendered families. The Constitution supports the rights of gay men and lesbians to establish life partnerships or, more recently, to enter into civil unions, to adopt children, keep custody of their own children in divorce proceedings, and to undertake co-parenting of their created families. Despite—or maybe because of—these developments, public debate on these issues is as lively and vociferous as it has ever been. At the time of writing this chapter, for instance, a veteran journalist published a column in a national newspaper in which he denounced same-gendered family “arrangements” as “neither the norm nor ultimately desirable” (Mulholland, 2013). Children in same-gendered families must be informed of this, he claimed. His argument was unsupported, save for unsubstantiated claims regarding the unnaturalness of same-gendered families, which defy “the natural order of things”, and the vehement refusal that “same-sex matrimony is the same as that of heterosexuals” (Mulholland, 2013). Mulholland’s column, which met with outrage by various activists and academics, demonstrates some of the ideas that circulate in public discussion of same-gendered families: concerns regarding the differences between homosexual and heterosexual families and the effects that these ‘differences’ might have on children living in ‘alternative’ families. In this chapter, we examine the public discussion, focusing on South African print media as a key site where debate has occurred. Recognising that the discussion of LGBTI issues in South Africa has increased in visibility over time, focusing on stories about coming out, rights, transgressions, stigma, discrimination and violence, this chapter concentrates on the public discussion in local print media that centre on ‘alternative’ family arrangements that are in contrast to a traditional heterosexual nuclear family. Drawing on a selection of print media reportage, we examine the social and public discourses that underpin and resist normative meanings associated with ‘the family’ as a social unit and, specifically, how same-gendered families (often rendered invisible and pathologised) are constructed within this material. , C.

- Description: publisher version , Professor Lawrence Schlemmer, affectionately known as Lawrie, was the father of South Africa’s quality-of-life studies and social indicators movement. He died on 26 October 2011 at the age of 75 after a short illness. In 1978, Lawrence marched into my office at the Centre for Applied Social Sciences, University of Natal, brandishing two books. We need to do some work on quality of life in South Africa, he announced, before handing me the volumes. At the time, South Africa’s leaders assumed that smiling black faces meant that South Africans were happy with their lot in life under apartheid. Our surveys were to prove otherwise. That weekend was spent reading cover to cover the classic works by Frank Andrews, Angus Campbell and their colleagues. The next week we pored over lists of concerns voiced by South Africans which we later put to test in the field. In 1982, we submitted our findings by ‘slug’ post to the editor of Social Indicators Research. We received a letter by return mail from Alex Michalos to say he would publish our paper and we should not be too disappointed with our regression results!

- Description: The status of South African farm workers has changed significantly over the past five decades. Using data from three major surveys conducted between 1957 and 2008, an Eastern Cape district was used as a case study to assess farmers’ perceptions of the changes that had occurred, particularly as a result of legislation. Considering the changes, the impacts on the farm labour market and wage and non-wage working conditions are analysed. The legislation focused on includes the Extension of Security of Tenure Act 62 (ESTA) of 1997, the Basic Conditions of Employment Act 75 (BCEA) of 1997 and minimum wage legislation. Farmers believed legislation had both positive and negative effects, which were compounded by changes in the political and economic contexts. The case study reveals that government has a role in improving the status of farm labourers, with education and healthcare services requiring special attention. However, caution is needed to ensure that further reductions in farm employment are restricted.

Female changes : the violation and violence of women in Ovid's Metamorphoses

- Description: Ovid’s interest in women and their lives is apparent throughout his texts, but is especially so in the Metamorphoses. This study analyses the violation and violence of women in the Roman poet’s epic and sets out to uncover the governing social mores and values that perhaps shaped the representations of women in the text. It examines how Ovid’s narratives may betray his values and attitudes and those of his audience as well as looking at the various ways that the poet and his rape episodes have been read. After surveying the literature on rape in Ovid’s Metamorphoses, Ars Amatoria and the Fasti, a brief historical context for the Metamorphoses is provided; women’s lives in Rome, the rape laws that existed during this time, as well as Roman sexuality are then examined. After this, a close textual analysis of different rape episodes in the Metamorphoses is presented, including the episodes of nymphs as victims, the silencing of rape victims and sexually ‘aggressive’ women, in order to reveal and examine the patterns that emerge. While Ovid’s intentions and attitudes towards women, as they are found in the Metamorphoses, have been read by some as sympathetic, by others as misogynistic and still others as more neutral, it is concluded that, although there is space for various readings, as a poet, Ovid was ‘opportunistic’ in his choice of materia and, above all, he wished to stimulate and delight his audience. While his personal values may not necessarily be reflected in his works and his readers may never know the ‘true’ intentions behind the poem, the Metamorphoses does hold up a mirror to the negative treatment of women and exposes the gender inequalities that existed during Ovid’s time. As a poet, however, Ovid’s conceived role is to entertain his audience and despite his somewhat problematic treatment of women and rape victims, he does just that.

- Description: The research which forms the basis of this thesis describes rural women’s perceptions of how Camfed education and skills development programmes have improved their lives in the Chikomba rural district in Chivhu, Zimbabwe. The researcher was motivated to carry out this study mainly due to the fact that in most rural societies in Zimbabwe, women are found suffering from social, cultural and political biases in the traditional male dominated society of Zimbabwe. Compared to their male counterparts, women have limited access to educational and employment opportunities and also have less social and political power than men. Being heads of households, women have to carry out the full traditional roles with the added responsibility of household and production management. The purpose of this study was to inform those investing and interested in women’s education about whether, how and the conditions under which women’s education directly improves women’s own lives and decreases poverty in the family and society. Camfed is an organization that advocates for female education particularly in the marginalized and poor parts of the country where poverty remains a barrier to girl’s education. It provides financial resources and establishes innovative education and training programs in order to break the poverty cycle in rural communities and empower women. A quantitative approach was employed in this study using a descriptive survey design, with the emphasis on collecting primary data from the research participants as well as consulting secondary data sources such as books, academic journals, completed and unpublished post-graduate research dissertations and theses. Findings of this study revealed that financial constraints, early marriage, proximity to school, death of parents as well as domestic chores were factors identified by the women that prevented them from completing school and pursuing further studies. The women also describe their perceptions of how education has led to better opportunities and an improved standard of living as they can now afford the basic goods and services. Moreover the participants mentioned how education has provided them with the basic skills to pursue a livelihood which will enable them to enjoy a decent standard of living. The research also found that education is an important determinant of women’s decision making in terms of finances and thereby improves their sense of empowerment. The women talked extensively about how education has raised their self-esteem and how it has enhanced their economic and social independence. At the end of the study and using the acquired information, several recommendations are made for the expansion and increase of programmes that offer incentives to keep girls in school, especially at secondary level where returns for girls are substantially greater in-terms of reducing poverty and improving the wellbeing of individuals.

- Description: This study examined how financial management decisions are made by small and medium enterprises (SMEs) in the Buffalo City Metropolitan in Eastern Cape, South Africa. The study aimed at discovering SME awareness on financial management practices. The financial management practices address issues on capital budgeting, working capital management, capital structure, financial reporting and analysis. The study, therefore, hypothesised that SMEs were not aware of the sound financial management practices. It was also intended in this study to examine the relationship between employment of sound financial management practices and firm financial performance. Subsequently, the study hypothesised that the employment of sound financial management practices by SMEs did not significantly affect their financial performance. The results obtained in this study revealed that SMEs were aware of the sound financial management practices that could be employed to yield high financial performance. However, the results also revealed that most SMEs were not employing qualified personnel and this in turn had an effect on the effectiveness of the financial management practices that the SMEs utilised. The findings also indicated that the employment of sound financial management practices did significantly and positively affect the financial performance of SMEs. The study recommended that SMEs could increase their chances of financial survival if they employ sound financial management practices. The study also gave recommendations to the South African Government to provide effective facilities and services to SMEs and help sustain them because they are important in the economy. Lastly, the study recommended financial institutions to relax their credit granting policies so that SMEs could access funds.

Financial structure and economic growth nexus: comparisons of banks, financial markets and economic growth in South Africa

- Description: The importance of the financial structure system, which comprises the banking sector and financial markets, to the growth of a country’s economy cannot be underestimated. It is important to analyse comparatively the contribution of each sector to the economic growth of a country. This study, therefore, empirically examined the relationship between financial markets, banks and economic growth in South Africa using time series analysis for the period 1990 to 2011. The study used the Vector Error Correction model (VECM) based causality tests to establish the link between financial structure (represented by both banks and financial markets) and economic growth. Real GDP was used as a measure for economic growth, Bank credit to the private sector was used as a proxy for the banking system, turnover ratio and value of shares traded was used as a measure for the stock market and bond market capitalisation was used as a measure for the bond market. To determine the net effects of financial structure on long run growth in South Africa, one control variable was added which was the ratio of government expenditure to GDP to control for the government’s role in the economy. The Johansen co-integration technique was also employed to obtain a long run relationship. The results from the study revealed that the stock turnover ratio, bond market capitalisation, and government expenditure have a long run relationship with economic growth while bank credit to private sector and value of shares traded showed a negative relationship with economic growth. With granger causality all the variables proved to granger cause economic growth except for bond market capitalisation where economic growth prove to granger cause bond market development. The study recommended that measures to improve liquidity, transparency and accessibility of both the banking sector and financial markets instruments should be a priority for South African authorities. The authorities should, therefore, encourage stock market development through an appropriate mix of taxes, legal and regulatory policies to remove barriers to stock market operations and thus enhance their efficiency since stock markets in Africa are underdeveloped. Strong financial regulation and supervision in banks to ensure efficiency in credit allocation should be done to enable channelling of credits to capital development rather than consumption spending.

- Description: Sustainable environmental practices need to be integrated into a university's infrastructural operations. Universities are entities that function within financial constraints with varying priorities across both administrative and educational functions. Unfortunately, these financial constraints often imply that a university's potential leadership role can only be realised should the viability (business case) of a proposed intervention be determined. This study focuses on the determination of a relational sustainable indicator and a relational cost factor. A relational sustainable indicator demonstrates how a university can collectively determine the contribution made to sustainability by various sectors of infrastructure. This is developed by means of a secondary study. Two components are important for calculating the relational sustainability indicator, namely, green infrastructure attributes and the basic elements of sustainability systems, namely, the environmental, economic and social dimensions of sustainability. The determination of a relational cost factor involves the quantification of the costs associated with alternative infrastructure provision. In particular, attention is paid to demand-side management costs, rationalising spatial growth costs, green building development costs, operation and maintenance of existing buildings costs, wastewater infrastructure costs, water infrastructure costs, energy infrastructure costs and transport infrastructure costs. Once the actual costs of each intervention category are determined, a relational sustainable cost factor can be calculated. Utilising the costs in the eight categories identified, a relational sustainable cost factor is determined. A resultant relational cost benefit as per the eight defined categories of sustainable infrastructure provision is derived from the relevant costs of sustainable infrastructure provision, the resultant relational cost factors and, finally, the relational sustainability indicators. It is proposed that that the determination of a budget split between the various interventions based on the resultant relational cost factor occur as follows: - Demand side management interventions: 15.97percent - Rationalising spatial growth: 6.72percent - Construction of green buildings: 24.37percent - Operations and maintenance: 21.85percent - Wastewater: 7.56percent - Water: 1.68percent - Energy: 12.61percent - Transport: 9.24percent. This study provides a platform to guide how and where to invest in sustainable infrastructure and provide direction in determining a budget split between various categories of sustainable infrastructure development.

- Description: Sustainable environmental practices need to be integrated into a university's infrastructural operations. Universities are entities that function within financial constraints with varying priorities across both administrative and educational functions. Unfortunately, these financial constraints often imply that a university's potential leadership role can only be realised should the viability (business case) of a proposed intervention be determined. This study focuses on the determination of a relational sustainable indicator and a relational cost factor. A relational sustainable indicator demonstrates how a university can collectively determine the contribution made to sustainability by various sectors of infrastructure. This is developed by means of a secondary study. Two components are important for calculating the relational sustainability indicator, namely, green infrastructure attributes and the basic elements of sustainability systems, namely, the environmental, economic and social dimensions of sustainability. The determination of a relational cost factor involves the quantification of the costs associated with alternative infrastructure provision. In particular, attention is paid to demand-side management costs, rationalising spatial growth costs, green building development costs, operation and maintenance of existing buildings costs, wastewater infrastructure costs, water infrastructure costs, energy infrastructure costs and transport infrastructure costs. Once the actual costs of each intervention category are determined, a relational sustainable cost factor can be calculated. Utilising the costs in the eight categories identified, a relational sustainable cost factor is determined. A resultant relational cost benefit as per the eight defined categories of sustainable infrastructure provision is derived from the relevant costs of sustainable infrastructure provision, the resultant relational cost factors and, finally, the relational sustainability indicators.

- Description: When creating artefacts that belong in the material world artists choose specific raw materials for particular reasons, including that selected resources are accessible and well suited to fitness for purpose and expression of intentions. Many potters in Africa are engaged in zero electricity usage ceramics practice, and each creative cycle usually starts with extracting clay from local sites according to preferences and well established procedures that may sometimes include certain rituals. Ways in which some potters who source their own clay are particular about certain factors that are thought to be capable of influencing the effectiveness of physical properties of that raw material are explored, with particular reference to what is known about the practices of Eastern Cape potter Alice Gqa Nongebeza, of Nkonxeni Village [31°37‘59.66“S, 29°23‘22.26“E], Tombo, near Port St Johns. Specific choices enacted by potters when gathering and using clayey raw materials are considered in order to better understand some aspects of conceptual and social frameworks that may influence clay extraction procedures. Thus, by means of comparisons between particular potter’s practices, as well as through analysis of interview material and observed events, this paper aims to contextualise how it transpired, inter alia, that clay seams close to the Nongebeza homestead were ignored by her in favour of a relatively distant and almost inaccessible site that yielded a particular clay well suited to her unique firing style of placing raw ware onto an already roaring bonfire, thereby effectively creating pots for daily use and enjoyment

- Description: Bangweulu Wetlands is a 6000 km² public-private-partnership conservation area in northeastern Zambia, lying on the south-eastern margins of the Bangweulu Swamps, Congo River system. The area is important for wildlife conservation, tourism and as a fishing ground for the local inhabitants. This study provides a baseline of the fish and fisheries of this area. The conservation area is situated on the transition zone between woodland, floodplain and swamp. A total of 42 fish species representing 12 taxonomic families were collected. The fish fauna of the area was characterised by a diversity of small cyprinids (14 species), cichlids (9 species), clariid catfishes (4 species) and mormyrids (4 species). Species such as Clarias gariepinus, C. ngamensis, Marcusenius macrolepidotus, Tilapia rendali, T. sparrmanii and several small Barbus species were shared with adjacent floodplain systems such as the upper Zambezi and Kafue rivers. Fishing was undertaken by fishing groups consisting of a fisherman and his family, or a group of men fishing together. Access to the fishing grounds was controlled by traditional fishing leaders, who collected tribute from fishermen. Fishing groups utilised fixed, distinct fishing areas determined by ancestry. The most important time for fishing was during the drawdown phase of the floodplains, from March until June. During the dry season fewer groups were engaged in fishing, with many having returned to farming activities. The main fishing methods of the floodplain fishery were basket traps and mosquito-mesh funnel nets set into earth fish barriers (fish weirs) constructed on the plains, various mesh sizes of gillnets, hook longlines and seine nets. The use of fish spears, drag baskets and piscicides was of lesser importance. Most fishing gears were constructed of a variety of natural and modern, manufactured materials. The fishery was multi-species and 23 fish species were recorded from in catch. The three most important species in the catches were C. gariepinus, T. rendalli and M. macrolepidotus. Together these contributed 67% by weight to the catch. Catch-per-unit-effort (CPUE) for the different gears was 0.4 ± 0.3 kg.trap.night⁻¹ for basket traps, 2.7 ± 4.6 kg.net.night⁻¹ for funnel nets, 0.3 ± 0.5 kg.50 m net.night⁻¹ for gill nets, 3.5 ± 6.3 kg.100 hooks.night⁻¹ for longlines, 1.79 ± 1.11 kg.haul⁻¹ for mosquito-mesh seine nets and 6.87 ± 6.27 kg.haul⁻¹ for larger-mesh seine nets. The weight of average daily landings of fishing groups, using a variety of gears was 7.8 ± 7.4 kg. Fishermen were able to maintain the same catch rate between dry and wet seasons, with no significant differences (p < 0.05) in daily landings between seasons. Yield per fisherman for a seven month season, which required 2-3 relocations due to falling water level, was 1.64 t based on catch assessment, and 1.9 t from a socio-economic survey. A tentative yield per area estimate for the area was 2I7 kg.ha⁻¹ over the three month shallow-floodplain fishing season. Most fish landed in the fishery were processed into sundried or smoke-dried products. These were used for 1) home consumption, 2) trade with village farmers (from up to 70 km inland of the fishing grounds) in exchange for staple starch meal, and 3) sold to urban fish traders, reaching markets as distant as Lubumbashi in Democratic Republic of Congo. Fish traders toured fishing camps to buy fish, supporting auxiliary industries such as transport and accommodation services. The price for dried fish at source was 3.14 ± 1.34 USDlkg and the market price reported for the Zambian Copperbelt was 6.14 ± 2.54 USD/kg. Typical returns on investment in fish trading were estimated as 68-77%. The fishery was considered to be biologically and socially sustainable. By harvesting a seasonally transient assemblage of species with high productivity and biological turnover rates and with life histories adapted to high mortality, fishermen were able to maintain a stable and viable livelihood. Management recommendations for the area were that a fisheries management plan be developed that would seek to strengthen the traditional system of rights-allocation, address problems between fishing and tourism activities, and enhance communication between fisheries and conservation stakeholders. To do this it was recommended that: 1) conservation authorities recognise the importance of the fishery, 2) no changes to current effort levels and fishing methods were necessary, 3) points 1 and 2 above be used to improve communication and trust between conservation authorities and fishermen, 4) customary resource-access mechanisms be understood and strengthened so that local inhabitants' rights to the resource are protected, 5) fishermen help formulate and accept conservation and tourism rules, 6) tourists and guides be made aware of the function of the fishery, 7) a fisheries management forum of key community, government and conservation stakeholders be formed to shape and implement the fisheries management plan, 8) locally-adapted bylaws be created to legitimise crucial floodplain gears currently considered illegal (e.g. mosquito-net gears, fish weirs), 9) no intervention to formalise fish trading be made, and 10) a trained person with a fisheries background be hired oversee the implementation of the recommendations.

- Description: The relationship between the convergence of a sequence of self mappings of a metric space and their fixed points, known as the stability (or continuity) of fixed points has been of continuing interest and widely studied in fixed point theory. In this thesis we study the stability of common fixed points in a Hausdorff uniform space whose uniformity is generated by a family of pseudometrics, by using some general notations of convergence. These results are then extended to 2-metric spaces due to S. Gähler. In addition, a well-known theorem of T. Suzuki that generalized the Banach Contraction Principle is also extended to 2-metric spaces and applied to obtain a coincidence theorem for a pair of mappings on an arbitrary set with values in a 2-metric space. Further, we prove the existence of coincidence and fixed points of Ćirić type weakly generalized contractions in metric spaces. Subsequently, the above result is utilized to discuss applications to the convergence of modified Mann and Ishikawa iterations in a convex metric space. Finally, we obtain coincidence, fixed and stationary point results for multi-valued and hybrid pairs of mappings on a metric space.
