- Description: Reports regarding the voltammetric properties of microbiological growth media are scarce in the literature and limited focus has been placed towards the application of electroanalysis for analyte monitoring in these complex media. This work aims to investigate the viability of voltammetry as a quantification method for analytes in microbiological growth media, using oxytetracycline (OTC) as a model analyte. Analysis of both commercially available and laboratory prepared growth media indicated the presence of interfering media components which produced anodic peaks at potentials ranging from ∼+0.85 V to ∼+1.30 V (vs. Ag/AgCl) under acidic conditions and ∼+0.62 V to ∼+1.35 V (vs. Ag/AgCl) under neutral pH. These peaks were identified as originating from proteinaceous components of growth media and correlated to the presence of peptone, malt extract and yeast extract. Electrochemical impedance spectroscopy demonstrated significant increases in the charge transfer resistance for Fe(CN)63−/4− redox probes at glassy carbon electrodes in the presence of peptone-comprised media (130.3 Ω) compared to media-free buffer (50.4 Ω). Adsorption of the aforementioned media components to the electrode surface thus contributes to analytical interference through faradaic and non-faradaic processes. By adapting the growth media for analyte detection purposes, this study proves the feasibility of detecting OTC, as well as the use of dilution of the media to further decrease the interferent effects of growth media. A 50-fold dilution of the media provided a 96.7% recovery of the OTC peak current at 20 μM concentration. The empirical detection limit of OTC in 50-fold diluted media was determined to be 0.5 μM, which makes it applicable to current industrial OTC fermentation processes.

- Description: Tax amnesties are government programs that typically allow a short period of time for tax evaders to voluntarily repay previously evaded taxes without being subject to penalties and prosecution that discovery of such tax evasion normally brings. Tax amnesties differ widely in terms of coverage, tax types, and incentives offered. A state’s Voluntary Disclosure Programme is another avenue available to taxpayers to assist them in resolving their state tax delinquencies. This programme is an on-going programme as compared to a tax amnesty, which is there for a limited time period only. The main goal of the research was to describe the tax amnesty and the voluntary disclosure programmes in South Africa and to assess their advantages and disadvantages. This thesis also discussed another form of voluntary disclosure programme, referred to as an Offshore Voluntary Disclosure Programme, which allows taxpayers with unreported foreign bank accounts, and presumably unreported foreign income, to voluntarily disclose their affairs. The study found that, due to tax amnesties, Government raises more tax revenue not only in the short run from collecting overdue taxes but also by bringing former non-filers back into the tax system for the long run. It was also found that, initially short-run revenue brought in from overdue taxes will be positive for the first amnesty and then decline each time the amnesty is offered repeatedly. The reason for the decline in revenue might be that tax amnesties provide incentives for otherwise honest taxpayers to start evading taxes because they will anticipate the offering of future amnesties, thereby weakening tax compliance. The costs associated with amnesty programmes include negative long run revenue impact and also that amnesty programmes reduce compliance by taxpayers in the long-run. In South Africa tax amnesties, especially the voluntary disclosure programme, are likely to be successful since they will increase the revenue yield and also bring non-filers back on the tax rolls.

- Description: This thesis examines the meanings that residents of the township of Hooggenoeg (in Grahamstown, in the Eastern Cape province of South Africa) made of the election coverage in the Grocott’s Mail newspaper during 2011 municipal elections in South Africa. In addition, this study also sought to understand the particular set of ‘normative roles’ played by the paper, both with reference to the well-established body of theory about the normative roles of journalism in a democracy, and in terms of the paper’s own conceptualisation of its role in the functioning of local democracy. Grocott’s Mail, the oldest independent newspaper in South Africa, provided extensive pre-election coverage, which included producing and distributing an unprecedented free edition of the paper. The paper also facilitated a town hall debate in order to encourage residents to vote, and empower them to make a more informed choice about their vote. Three qualitative research methods, namely qualitative content analysis, focus group interviews, and individual interviews were used to examine the relationship between the content provided by the paper and the audience’s process of ‘making sense’ and deriving meaning from the content provided. The study concludes that Grocott’s attempt to encourage democratic culture in Grahamstown, in keeping with the more ‘facilitative’ normative roles that the local media can play, was only partially successful. Much of the election reporting subordinated the voices of the ordinary people, and privileged reporting that focussed narrowly on the voting process, and which foregrounded the views of political parties. Overall this coverage largely failed to resonate with the Grocott’s readers who live in Hooggenoeg (a largely ‘coloured’ area of Grahamstown), whose key concerns in terms of their daily life – such as poverty, unemployment, crime, lack of services – seemed, to them, unaddressed by this election coverage and, consequently, was not as engaging or convincing as the publishers/editors had hoped it would be. It can be also argued that Grocott’s narrow conceptualisation of democracy as entailing only public participation in electoral processes failed to cater for how audiences can be made aware of how they can participate in governance beyond the election period.

- Description: Climate variability and change as well as sea level rise poses significant challenges to livelihoods, water and food security in small island developing states (SIDSs) including the Zanzibar Islands. Thus, without planned strategic adaptation, the future projected changes in climate and sea level will intensify the vulnerability of these sensitive areas. This thesis is based on research conducted in two sites located in the north eastern parts of each island, namely Kiuyu Mbuyuni, Pemba Island and Matemwe, Unguja Island. The research focused firstly on assessing the vulnerability of these two coastal communities to climate variability and change and other stressors. This included investigation of (1) the perceptions of fishers, farmers and seaweed farmers regarding climate stressors and shocks and associated risks and impacts, (2) existing and possible future water and food security issues, and (3) household's access to important livelihood assets. This was followed by an exploration of the coping and adaptive responses of farmers, fishers and seaweed farmers to perceived shocks and stresses and some of the barriers to these responses. Lastly, an analysis of the implications of the findings for achieving sustainable coastal livelihoods and a resilient coastal community was undertaken. The general picture that emerges is that local people along the east coasts of both islands are already vulnerable to a wide range of stressors. Although variability in rainfall is not a new phenomenon in these areas, increasing frequency of dry spells and coastal floods resulting from the influence of El Niño and La Niña events exert enormous pressures on local activities (fishing, farming and seaweed farming) which are the crux of the local economy. The main argument of the study is that the nature and characteristics of these activities are the main source of sensitivity amongst these communities and this creates high levels of vulnerability to climate shocks and trends. This vulnerability is evidenced by the reoccurrence of localised food shortages and the observed food and water insecurity. The study found that food insecurity is a result of unreliable rainfall, drought and seasonality changes. These interacted with other contextual factors such as poor soil, low purchasing power and the lack of livelihood diversification options. In addition to exposure to these almost unavoidable risks from climate variability, the vulnerability of the local communities along the east coasts is also influenced by the low level of capital stocks and limited access to the assets that are important for coping and adaptation. Despite this, some households managed to overcome barriers and adapt in various ways both within the three main livelihood sectors (fishing, farming and seaweed farming) as well as through adopting options outside these sectors resulting in diversification of the livelihood portfolio. However, the study found that most of the strategies opted for by fishers, farmers and seaweed farmers were mainly spontaneous. Few planned adaptation measures supported by state authorities were observed across the sites, with the exception of the provision of motorised boats which were specifically meant to increase physical assets amongst fishers, reduce pressure in the marine conservation areas and prevent overfishing in-shore. Furthermore, numerous strategies that people adopted were discontinued when further barriers were encountered. Interestingly, some of the barriers that prevented households adapting were the same ones that forced households that had responded to abandon their adaptations. To increase resilience amongst east coast communities to current and future predicted changes in climate and sea level, the study argues that traditional livelihood activities (fishing, farming and seaweed farming) need to be better supported, and access to a range of livelihood assets improved. This may be achieved through increased access to local sources of water and facilitation of rainwater harvesting, expanding the livelihood options available to people and increasing climate change awareness, and access to sources of credit.

- Description: [From Introduction] In South Africa, social grants are a central component of government's efforts to alleviate poverty. The number of people receiving social grants has significantly increased in recent years (from about 10.9 million in 2005 to almost 15.7 million in 2013, and an anticipated 16.8 million recipients by 2015).With social grants playing an increasingly important role, a pressing policy issue is whether or not the current social grant schemes are an effective tool for alleviating poverty. Some studies have shown that social grants improve food security (Case and Deaton, 1998; Samson et al., 2008) and in the long run can promote employment through accumulation of human capital and enhancing productivity of poor households (Edmonds et al., 2006; Samson et al., 2008; Surender et al., 2007). However, other studies have reported that social grants have possible disincentive effects on labor market activity, for example, through the relaxing of household budget constraints which may lead to a reduction in labor supply (Bertrand et al., 2003; Ranchorhod, 2006; Klasen and Woolard, 2009). Our study provides new insights by highlighting two key household characteristics, gender and education, in catalyzing or diminishing the effects of grants on household livelihood outcomes. Our analysis mainly focuses on impacts of pensions on household food security and labor supply of household members.

- Description: Knowledge of water use, through water foot printing (WF) in smallholder agriculture crop production is the key to the global fight against poverty, achievement of food security and sustainability within the world’s rural community. Water footprint of a crop can be defined as the volume of fresh water used to produce a certain crop in all the steps in the production line. This study, therefore aimed at contributing towards improvements in rural livelihoods by raising awareness of the increased productive use of green, blue and grey water in smallholder agriculture in South Africa. This was done through determination of water footprints of five vegetable crops, i.e. potatoes (Solanum tuberosum), tomatoes (Solanum lycopersicum), dry beans (Phaseolus vulgaris), cabbage (Brassica oleracea spp) and spinach (Spinacia oleracea) in the 2000-2013 period. Quantification of water footprints has been done worldwide but, in South Africa (SA) focus has mostly been on the industrial and domestic sector. Water footprint assessment framework, was used to estimate the full impact of vegetable production on water resources at Zanyokwe, Thabina and Tugela Ferry irrigation schemes as case studies. The CROPWAT@ model was used to calculate crop evapotranspiration, differentiating green and blue water. Local climatic data were obtained from SA weather services, while the crop and soil parameters were obtained from the FAO data base. Nitrogen was considered the main pollutant hence its use in the grey water footprint calculation. Generally, Thabina irrigation scheme had the highest water footprint, followed by Tugela Ferry irrigation scheme whilst Zanyokwe irrigation scheme had the lowest. Green beans had the highest water footprint at all the three irrigation schemes with Thabina irrigation scheme having the highest (3535.1 m3/ton). For Tugela Ferry irrigation scheme, the calculated WF was 2753 m3/ton whilst the lowest was observed at ZIS i.e. 2407.6 m3/ton. Cabbage had the lowest water footprint. The highest water footprint for growing cabbage was 254.5 m3/ton in TFIS, 223.1 m3/ton in TIS and the lowest was 217.8 m3/ton in ZIS. The differences observed in the WF of a crop at each scheme maybe attributed to the differences management, weather and environmental characteristics, in the three locations. Moreover, the needs for ET are related to soil type and plant growth, and primarily depend on crop development and climatic factors which are closely related to climatic demands. The grey water footprint was calculated using the recommended fertilizer application rates for all the three sites. Green beans had the highest WFgrey i.e. 373 m3/ton and the lowest was cabbage with 37 m3/ton. Potato, spinach and tomatoes had 156 m3/ton, 214 m3/ton and 132 m3/ton, respectively. Grey water footprint in this study was higher as compared to other studies, possibly because of the high rates of nitrogen fertilizers used in the calculations and the low yields farmers get. Compared with estimates from other studies, the water footprints of vegetable production within smallholder irrigation schemes was relatively high. There is therefore, a need to focus on crop management and tillage practices that will help in increasing yield while minimizing water usage.

Local climatic data were obtained from SA weather services, while the crop and soil parameters were obtained from the FAO data base. Nitrogen was considered the main pollutant hence its use in the grey water footprint calculation. Generally, Thabina irrigation scheme had the highest water footprint, followed by Tugela Ferry irrigation scheme whilst Zanyokwe irrigation scheme had the lowest. Green beans had the highest water footprint at all the three irrigation schemes with Thabina irrigation scheme having the highest (3535.1 m3/ton). For Tugela Ferry irrigation scheme, the calculated WF was 2753 m3/ton whilst the lowest was observed at ZIS i.e. 2407.6 m3/ton. Cabbage had the lowest water footprint. The highest water footprint for growing cabbage was 254.5 m3/ton in TFIS, 223.1 m3/ton in TIS and the lowest was 217.8 m3/ton in ZIS. The differences observed in the WF of a crop at each scheme maybe attributed to the differences management, weather and environmental characteristics, in the three locations. Moreover, the needs for ET are related to soil type and plant growth, and primarily depend on crop development and climatic factors which are closely related to climatic demands. The grey water footprint was calculated using the recommended fertilizer application rates for all the three sites. Green beans had the highest WFgrey i.e. 373 m3/ton and the lowest was cabbage with 37 m3/ton. Potato, spinach and tomatoes had 156 m3/ton, 214 m3/ton and 132 m3/ton, respectively. Grey water footprint in this study was higher as compared to other studies, possibly because of the high rates of nitrogen fertilizers used in the calculations and the low yields farmers get. Compared with estimates from other studies, the water footprints of vegetable production within smallholder irrigation schemes was relatively high. There is therefore, a need to focus on crop management and tillage practices that will help in increasing yield while minimizing water usage.

- Description: In the last decade, there has been an increase in the number of web-enabled mobile devices, offering a new platform that can be targeted for the development of learning applications. Worldwide, developers have taken initiatives in developing mobile learning (M-learning) systems to provide students with access to learning materials regardless of time and location. The purpose of this study was to investigate whether it is viable for first year students enrolled at the University of Namibia (UNAM) to use mobile phones for ad-hoc learning of mathematical concepts. A system, EnjoyMath, aiming to assist students in preparing for tests, examinations, review contents and reinforce knowledge acquired during traditional classroom interactions was designed and implemented. The EnjoyMath system was designed and implemented through the use of the Human Centred Design (HCD) methodology. Two revolutions of the four-step process of the HCD cycle were completed in this study. Due to the distance between UNAM and Rhodes University (where the researcher was based), the researcher could not always work in close relation with the UNAM students. Students from the Extended Study Unit (ESU) at Rhodes University were therefore selected in the first iteration of the project due to their proximity to the researcher and their similar demographics to the first year UNAM students, while the UNAM students were targeted in the second iteration of the study. This thesis presents the outcome of the two pre-intervention studies of the first-year students' perceptions about M-learning conducted at Rhodes University and UNAM. The results of the pre-intervention studies showed that the students are enthusiastic about using an M-learning system, because it would allow them to put in more time to practice their skills whenever and wherever they are. Moreover, the thesis presents the different stages undertaken to develop the EnjoyMath system using Open Source Software (PHP and MySQL). The results of a user study (post-intervention) conducted with participants at UNAM, ascertained the participants' perception of the usability of the EnjoyMath system and are also presented in this thesis. The EnjoyMath system was perceived by the participants to be "passable"; hence an M-learning system could be used to compliment an E-learning system at UNAM.

- Description: Tomi Ahonen, credited with introducing the concept of mobile as the seventh mass media, notes that the arrival of the mobile phone was a God-send for advertisers, as it is the only mass medium where the audience can be accurately identified. Conversely, the pervasiveness of location-aware, multi-sensor, permanently on and constantly connected devices raised privacy concerns about carrying "little brother" in your pocket at all times. One of the distinctive characteristics of mobile phones, setting them apart from all previous media, is the fact that they are personal devices: 60% of married users would not let their spouse access their mobile phone and, not surprisingly, teenagers are even less inclined to let their family members have a look at their device. Things have not always been so. In South Africa, research conducted among university students revealed that for many a hand-me-down phone the size of a brick and shared with siblings was their first mobile device.

- Description: Foreign Direct Investment (FDI) flows into South Africa have been very low for several decades, and this research examines the reason(s) why this has been the case since 1994. There is a common belief amongst economists that there is a positive relationship between the amount of FDI received and economic growth, thus the desire to attract greater FDI inflows. A literature review was conducted to establish the determinants of FDI globally and then data were collected and assessed to test which causes are most important. The performance of developing nations in attracting FDI was first compared with that of the developed nations. Thereafter, a regional breakdown of FDI flows was presented, with a particular focus on the Southern African region. FDI inflows to South Africa since 1994 were compared against the identified determinants of FDI, as well as with FDI inflows into two other major mining economies, Chile and Botswana. The friendliness of the government towards business was identified as a significant determinant of FDI inflows and the importance of this factor in explaining FDI inflows into environment in South Africa was looked at in more depth. It was found that many investors perceive the South African government as hostile towards business and as corrupt and/or inefficient. The empirical results show that this negative perception helps explain the FDI inflows attracted by South Africa since 1994. Therefore, increased friendliness to business by the government should increase future inward FDI flows into South Africa.

- Description: An ethnobotanical survey was conducted in Alice and Willowvale in the Nkonkobe and Mbashe municipalities of the Eastern Cape Province, South Africa to identify and document wild vegetables growing in the areas. The survey documented 22 vegetable species belonging to 12 different families. The Amaryllidaceae, Amaranthaceae, Apiaceae, Asteraceae, Caryophyllaceae, Chenopodiaceae, Convolvulaceae, Cruciferae, Cucurbitaceaea, Euphorbiaceae, Tiliaceae, Solanaceae, Polygonaceae and Urticaceae were the families that were recorded. The species were Tulbaghia violacea Harv., Amaranthus blitoides S., Amaranthus blitum L., Amaranthus hybridus L., Centella coriacea Nannfd., Bidens pilosa L, Cotula heterocarpa DC., Sonchus oleraceus L., Galinsoga parviflora Cav., Taraxacum officinale Weber, Hypochaeris radicata L., Stellaria media L., Chenopodium album L., Chenopodium murale L., Ipomoea batatas L., Sisymbrium thellungii O. Schulz, Cucurbita pepo L., Rumex crispus L., Acalypha virginica L., Nicandra physalodes L., Physalis peruviana L., Solanum nigrum L., Urtica urens L. and Corchorus olitorius L. About 27 % of the wild vegetables were native to South Africa and about 45 % were also used as medicinal plants in the areas. Sun drying was the most common method of preserving the wild vegetables for the off season months. This study also revealed that, men and the younger generation knew less about wild vegetables than the women. The study also revealed a loss of knowledge of wild vegetables and their use by the rural dwellers who are more in favour of the exotic types such as spinach and cabbage.

- Description: Marine and coastal ecosystems face widespread degradation largely because market failure hides the economic value of the goods and services provided by them. Marine protected areas (MPAs) can serve as a structure that ensures the continuing function of marine and coastal ecosystem goods and services. Yet, to be effective and sustainable, MPAs must be able to prove their economic worth and generate revenue. User-fees are a common system used to partially finance multi-use MPAs. This study applies contingent valuation as a method of economic valuation within an MPA in southern Mozambique. The objectives of this study are to determine the willingness to pay of combined user groups and of individual user groups for use of the Ponta do Ouro Partial Marine Reserve and to investigate the potential for the reserve to increase revenues for conservation through the implementation of a user-fee for marine based activities. The payment card contingent valuation method was employed to determine willingness to pay of dolphin swim tourists, scuba divers and fishermen. Data was collected by face-to-face interviews of 120 respondents within two popular tourist locations in the PPMR. Results show that visitors within the PPMR are mainly South Africans, loyal to the area. Probit and OLS regressions were used to determine the effects of various independent variables on willingness to pay. Results from the Probit model indicate that African residency, activity and environmental awareness were significant factors that influenced visitors being WTP more than R20 per person per day as a user fee within the PPMR. The OLS model examined independent variables that influenced visitors being willing to pay as well as the impact of the variables on the amount visitors were willing to pay. The OLS model found income, African residency and environmental awareness to be significant factors influencing visitors being willing to pay. The mean WTP was R43.75 per person per day. Using data supplied by the PPMR, conservative estimated annual revenues based on the implementation of this fee amount would range between R1.46m – R 3.3m.

- Description: The South African food and clothing retail industry is highly sophisticated and dominated by a few large competitors. The market is unique and has been shaped by abnormal political influences that have created a polarised society. The market holds a high potential owing to the burgeoning young middle class that is also attracting global attention. This necessitates an increase in economies of scale through expansion and acquisition strategies. Woolworths Holdings Limited has experienced significant growth in tough trading conditions whilst many competitors have lost ground. The Woolworths’ brand is primarily aimed at the high-income groupings but also appeals to the burgeoning middle class with their private-label products. The clothing and food divisions also provide a unique appeal that concentrates on the strong brand name to cater to the polarised nature of the market. The Woolworths Holding Limited (WHL) business model aims to offer superior quality at a lower cost than competitors which competitors find difficult to imitate. The apparent paradox is solved through tightly-knit supplier relationships and a culture demanding continuous improvement. The company is uniquely positioned to service the Living Standards Measure (LSM) 8-10 niche market whilst improving efficiencies. The company drives its competitive advantage over competitors through the key competencies of a reputable brand name, a strong sustainability programme, a strong operation and supply chain network, all of which are crucially-supported by superior and innovative technology utilisation. The study analysed the strategic brand positioning with a focus on the introduction of the supermarket concept. The study indicated that the supermarket concept was a reaction from WHL to consumer’s requirements for a one-stop shop aimed at increasing existing customers’ basket spend and drawing similar new clients. An increase in spend is potentially lucrative to WHL, and the strategy is a viable option as long as the company remains focussed on the core principles of the business model.

- Description: This study examines Work Family Conflict including Work Interferes with Family (WIF) conflict, Family Interferes with Work (FIW) conflict, role overload, role interference and the impact of children across various life and career stages. Much of the research in this area focuses on the differences in the way the genders experience Work Family Conflict. Research has shown that various life and career stages can have a marked impact on this type of conflict and this study aims to determine how individuals in the various life and career stages experience this conflict. A correlational research design was used for this study. Using a five point likert scale, participants were asked to score their responses to seventeen items. The instrument was based on Duxbury and Mills Measure of Work Family Conflict (1990) (in Handbook of Quality-of-Life Research: An Ethical Perspective by Sirgy, 2001) with the inclusion of two additional items due to their high face validity. The questionnaire was distributed to human resources managers in organisations, friends, family members and colleagues and friends, family members and colleagues of theirs. Most of the responses were scored using a pencil and paper technique and the remainder was distributed using a Surveymonkey application on social media platforms like Facebook and Linkedin. The overall sample size of respondents was 175. The raw data was entered on an excel spreadsheet and analysed using Statistica version 12 and Microsoft Excel applications with VBA macros developed by a consultant for the Nelson Mandela Metropolitan University Unit for Statistical Consultation. . Statistics such as means, Cronbach alpha’s, relationships between factors, descriptive statistics, MANOVA and Chi-squared tests were used to analyse the data. The results of this study demonstrate the need for organisations to take heed of the various challenges that individuals face in both the workplace and home environment and the different ways in which these are experienced across various life and career stages. This will enable them to design specific interventions to mitigate the effects of Work Family Conflict and improve employee’s level of performance.

- Description: Discipline is crucial in the provision of quality public service work. This is because most citizens are serviced through the public service work. Adhering to rules and orders, exercise of self control and the ability to put needs of others over one’s own needs are fundamental aspects of discipline. Every workplace has its own pieces of legislation that are used as a guide on expected conduct as well as a tool to deal with failure to adhere to the outlined pieces of legislation governing the conduct in the workplace. There are institutions in place that deal with the crafting of the pieces of legislation which clearly outline the manner in which both the employer and employee should conduct themselves as well as rights of both parties as they interact in the employment relationship. The existing pieces of legislation as well as their implementation and relevance in this era needs to be closely scrutinised and critique with proposals within the prescripts of legislation is necessary as some pieces of legislation seem to be conclusive, thereby undermining procedures followed when dealing with cases of misconduct. In any disciplinary process, the sanction should be in line with the process as it has unfolded and not be influenced by how a piece of legislation is crafted. The Public Service Act, Employment of Educators’ Act and the Labour Relations Act 66 of 1995 are key statutes in dealing with discipline in public education. Sanctions for misconduct are dependent on the gravity of the misconduct. In order to discipline educators, sections 17 and 18 of the Employment of Educators Act are used as guides on processes and procedures to be followed.

- Description: Discipline is crucial in the provision of quality public service work. This is because most citizens are serviced through the public service work. Adhering to rules and orders, exercise of self control and the ability to put needs of others over one’s own needs are fundamental aspects of discipline. Every workplace has its own pieces of legislation that are used as a guide on expected conduct as well as a tool to deal with failure to adhere to the outlined pieces of legislation governing the conduct in the workplace. There are institutions in place that deal with the crafting of the pieces of legislation which clearly outline the manner in which both the employer and employee should conduct themselves as well as rights of both parties as they interact in the employment relationship. The existing pieces of legislation as well as their implementation and relevance in this era needs to be closely scrutinised and critique with proposals within the prescripts of legislation is necessary as some pieces of legislation seem to be conclusive, thereby undermining procedures followed when dealing with cases of misconduct. In any disciplinary process, the sanction should be in line with the process as it has unfolded and not be influenced by how a piece of legislation is crafted. The Public Service Act, Employment of Educators’ Act and the Labour Relations Act 66 of 1995 are key statutes in dealing with discipline in public education. Sanctions for misconduct are dependent on the gravity of the misconduct. In order to discipline educators, sections 17 and 18 of the Employment of Educators Act are used as guides on processes and procedures to be followed.

- Description: Using the late twentieth-century French feminist notions of écriture féminine and the abject as a starting point, this article considers the various pitfalls, effects and ethical ramifications of representations of violence against the female body in South African crime fiction. How do authors reconcile the entertainment value of such representations with their aims to perform social analysis? This article attempts to answer this question by first describing how violence targeted at the female body is graphically portrayed, and, second, by assessing the effects of these visceral descriptions. Margie Orford’s novels, in particular, the first in the Clare Hart series, Like clockwork (2006), which foregrounds human trafficking, prostitution and gender-based violence, will be examined. In Orford’s Clare Hart series, the female detective figure, the various plots to do with assault, abduction, rape and murder, and the explicit imagery that descriptively conveys such crimes, are narrative techniques employed by Orford to address this scourge, and the patriarchy and sexism of contemporary South African society in general. The article ends by assessing whether a bona fide feminist subgenre of South African crime fiction is being inscribed by Orford

- Description: African foreigners in South Africa have frequently been the targets of violent and discriminatory practices, which occur in the enabling context of negative discourses concerning African foreigners that circulate in various spheres of public life. This study is interested in one particular field of interaction between African foreigners and the South African state, namely the public health sector. Discriminatory and, sometimes, violent practices towards African foreigners on the part of South African citizens are widely documented. Less discussed are the ways in which these practices of violence and discrimination are in fact state practices. We show this with reference to the treatment of African foreigners in the public health sector. We refer to this prejudicial treatment as health-care Xenophobia which is made possible by a wider set of discourses related to citizenship and the rights accruing to citizens which suggest the ‘non-rights’ of the non-citizen.

- Description: Zimbabwe Takes Back its Land offers a useful introduction to fast-track land reform in contemporary Zimbabwe for a broad popular audience unfamiliar with the existing literature on fast-track land reform. But its value as a contribution to a more specialised and nuanced body of knowledge about fast-track is considerably more problematic.
