- Description: Since the deregulation of Voice over Internet Protocol (VoIP) in 2005, many South African organizations are now attempting to leverage its cost saving and competitive values. However, it has been recently cited that VoIP is one of the greatest new risks to organizations and this risk is cited to increase Information Security insurance premiums in the near future. Due to the dynamic nature of the VoIP technology, regulatory and legislative concerns such as lawful interception of communications and privacy may also contribute to business risk. In order to leverage value from the VoIP implementation, an organization should implement the technology with knowledge of the potential risk of civil liability. This is further highlighted by the King III Report which indicates that the Directors of an organization should be ultimately responsible for Corporate Governance and, therefore, IT Governance and Information Security Governance. The report goes further to say that any newly implemented technology, such as VoIP, should comply with all South African legislation and regulations. This responsibility encourages the practice of both due care and due diligence. However, recent trends exercised by Information Security professionals, responsible for drafting Information Security policies and related procedures, often neglect the regulatory requirements and choose to only implement international best practices with no consideration of the risk of civil liability. Although these best practice frameworks may inadvertently comply with existing local legislation, a chance of an oversight is possible. Oversights may not only result in criminal sanctions, but also civil action due to losses or damages suffered. With regard to implementing VoIP, good Corporate Governance could potentially be ensured through the use of both identified regulations and relevant international best practices. This dissertation aims to aid organizations in avoiding or at least mitigating the risk of civil liability to better leverage VoIP’s value, through good Corporate Governance practices. This should aid in the exercise of due care and due diligence when implementing VoIP as a means of conducting business communication.

- Description: The research seeks to explore why women in Zimbabwe still face hindrances in accessing micro finance services and what can be done to meet their needs in a more holistic and effective way. Women play a crucial role in the economic development of their families and communities but are faced with certain obstacles that hinder them from performing their role effectively. Such hindrances as poverty, unemployment, low household income and societal discrimination. UNIFEM (1992) confirms that the majority of the world‟s poor have a predominantly female face and argues that women earn only 10 percent of world‟s income and own less than 10 percent of the world‟s property. African women have been characterised by the lack of empowerment caused by societal perceptions and negative cultural practice. In many cases of women rights violation it has been noted that this has been exacerbated by the over reliance on the male counterpart. Development practitioners have noted that micro finance as one of the strategies needed for women empowerment. Despite the concept having been practiced for at least 15 years now, women still face challenges in accessing micro finance services. There is need for Micro Finance Institutions to recognise the position of women in relation to men as actors in society.

- Description: An understanding of species specific water quality requirements is essential for efficient production of aquaculture products, an aspect not well documented for the land-based culture of the South African abalone, Haliotis midae. In order for the industry to remain competitive in international markets, efficient use of water supplies and the development of water reuse technology is needed. This study assessed the changes in water quality between tanks in a tiered serial-use raceway in relation to accumulated biomass and water flow and estimated the flow index (FI) (L h⁻¹ kg⁻¹) at which growth becomes significantly affected. The effect of dietary protein level, supplementation of pure oxygen and addition of sodium hydroxide (NaOH⁻) on water quality and fundamental production parameters in the serial-use raceways was also assessed. The serial-use raceways were used as a tool to create a range of water quality conditions at which the growth, feed conversion ratio (FCR) and condition factor (CF) of "cocktail" size (60 – 70 mm) H. midae could be monitored. The metabolic activity of the abalone resulted in a deterioration in water quality between tanks in series. pH (r² = 0.99; p < 0.001) and dissolved oxygen concentration (r² = 0.99; p < 0.001) were positively correlated with flow index (pH = 7.38 FI°·°² ; dissolved oxygen = 6.92 FI°·°⁴), while free ammonia nitrogen (FAN) (r² = 0.99, p < 0.001) and nitrite (NO²⁻ - N) (r² = 0.93, p < 0.001) were negatively correlated with flow index (FAN = 8.02 FI⁻°·⁷¹). Nitrite concentrations increased over time indicating colonisation of Nitrosomonas bacteria on the basket surfaces. A flow index of 7.2 – 9.0 L h⁻¹ kg⁻¹ was estimated as the minimum to avoid significant reductions in weight and shell length gain and increases in FCR values. Total ammonia nitrogen (TAN) and FAN concentrations were significantly correlated to dietary protein (P) (t = 6.63, p < 0.0001 and t = 6.41, p < 0.0001, respectively) and flow index (t = 5.42, p < 0.0001 and t = 3.9, p < 0.0002, respectively) and could be estimated using the models TAN = 9.73 P – 110.3 log (FI), and FAN = 0.132 P – 1.10 log (FI). Mean FAN concentrations were 67 and 41 % lower in tanks fed a diet containing 22 and 26 % protein respectively, when compared to tanks fed a 33 % protein diet. Supplementation with pure oxygen (103 ± 8 % saturation) improved shell length gain (t = 3.45, p = 0.026) in abalone exposed to high FAN (2.43 ± 1.1 μg L⁻¹) and low pH (7.6 ± 0.13), relative to a treatment with no oxygen supplementation (92 ± 6 % saturation). Addition of a sodium hydroxide solution resulted in elevated mean pH in treatment raceways when compared to control raceways. The increased pH resulted in significantly higher weight gain (g abalone⁻¹) (F₁·₁₂ = 4.51; p = 0.055) and shell length gain (mm abalone⁻¹) (F₁·₁₂ = 4.56; p = 0.054) at an α-error level of < 5.5 %. In two trials, weight gain and shell length gain were significantly correlated to pH (p < 0.001), and multiple regression of pH, dissolved oxygen and FAN consistently revealed pH to be the best predictor of growth. It is therefore suggested that decreasing pH is the first limiting water quality variable for abalone in serial-use raceways. As a decrease in water pH is linked to respiration by the abalone and subsequent increase in dissolved carbon dioxide (CO₂) concentration, future studies should examine the effects of CO₂ on H. midae metabolic rate, calcification rate and health. The results of this study will contribute toward our understanding of the specific water quality requirements for H. midae in commercial aquaculture systems, and influence the design and management procedures for abalone water reuse systems.

- Description: This study deals with water service delivery for improved quality of life in the Mbizana Local Municipality. The study sets out to determine how the inner workings of water service delivery work in the Mbizana Local Municipality, situated in the Eastern Cape, and how this should function in terms of South African legislation. The objectives of the study are to understand the current state of water service delivery in the Mbizana Local Municipality, finding out information about South African legislation regarding the ideal state of water service delivery, and recommending development programmes to improve water service delivery. This study is about understanding trends in the body of scientific knowledge or literature, and studying (as objects) the ideas and writings of other scholars. No empirical study was conducted. The research methodology for this study is descriptive, with data sourced from available literature. The findings in this study indicate that backlogs for water service delivery remain high in the Mbizana Local Municipality. Regrettably, the situation has worsened since 2004; backlogs have shifted from 45 percent to 94 percent of households with no access to tap water. A number of normative criteria to deal with the research problem were extracted from available literature, from which conclusions were drawn and recommendations made.

- Description: Zoonotic diseases are diseases that are transmitted from animals or vectors to humans and vice versa. The public together with veterinarian authorities should readily access disease information as it is vital in rapidly controlling resultant zoonotic outbreak threats through improved awareness. Currently, the reporting of disease information in South Africa is predominantly limited to traditional methods of Information Communication Technologies (ICTs) like faxes, monthly newspaper reports, radios, phones and televisions. Although these are effective ways of communication, their disadvantage is that the information that most of them offer can only be accessed at specific times during a crisis. New technologies like the internet have become the most efficient way of distributing information in near-real-time. Many developed countries have used web-based reporting platforms to deliver timely information through temporal and geographic visualisation techniques. There has been an attempt in the use of web-based reporting in South Africa but most of these sites are characterised by heavy text which makes them time consuming to use or maintain. As a result most sites have not been updated or have ceased to exist because of the work load involved. The success of web reporting mechanisms in developed countries offers evidence that web-based reporting systems when appropriately visualised can improve the easy understanding of information and efficiency in the analysis of that data. In this thesis, a web-based reporting prototype was proposed after gathering information from different sources: literature related to disease reporting and the visualisation of infectious diseases; the exploration of the currently deployed web systems; and the investigation of user requirements from relevant parties. The proposed prototype system was then developed using Adobe Flash tools, Java and MySQL languages. A focus group then reviewed the developed system to ascertain that the relevant requirements had been incorporated and to obtain additional ideas about the system. This led to the proposal of a new prototype system that can be used by the authorities concerned as a plan to develop a fully functional disease reporting system for South Africa.

- Description: This treatise investigates the representation of career opportunities for young girls as portrayed in three English-medium newspapers published in the Nelson Mandela Bay in 2010.While there have been numerous researches on the representation of women in the media, studies on career opportunities for young girls have yet to be conducted. Previous studies have established that girls were socialized to occupy nurturing roles in society: through parents, schools and social institutions like churches were chief socialization instruments. The use of language and rhetoric in the media often reiterates this socialization. Due to the power of the media to influence perceptions, this research reflects on the messages obtained by readers of the publications. The research is important because it aims to identify the trends of representation of career and life opportunities for girls in: The Herald, the Weekend Post and La Femme newspapers. A pilot study of articles on women and young girls was completed; this was followed by a main study. A content analysis of articles only on women and girls was conducted; whilst articles on young boys and men were excluded from this research, as its main focus was on women. The theoretical frameworks applied were the theories of journalism and feminism to determine the nature of representation. While the media organisations operate solely as a business, whose interest is to make profit, they have the fundamental responsibility of promoting values, particularly in South Africa. Under the leadership of the ANC-led government, plans have been executed to promote a 50/50 representation in government. Also, the participation of women in the private sector has improved through the requirements of the policy of Black Economic Empowerment, which aims to redress the wrongs of the past. This project has established that although the world has embraced feminism and the equality of women and men, much still needs to be done to reinforce these ideals, especially in the socialization of children.

- Description: The sense of region in Southern Africa is based on nationalism and its struggles for national liberation. Unusually, the norms of smaller states initially shaped the region's scope and culture of interaction. First and foremost, cooperation happened in the area of security, an initial focus being to uphold the independence and sovereignty of the state in the face of challenges from apartheid South Africa. As such, rather atypically, intergovernmental security cooperation preceded broad based economic cooperation. This has meant that security and development have remained largely de-linked and this has helped discourage implementing a society or human rights centred approach to security. Cooperation has been made more difficult by disparate political systems with divergent values, cultures, agendas and sensibilities. As such, regionalism reinforces nationalism to the exclusion of development or wider notions of political and social security. The region amounts to a security regime with only a patchy record in advancing security. Therefore, in the face of developmental challenges and unless a degree of strategic coherence along political and policy fronts is reached, after 20 years of SADC the endeavour to institutionalise security in conventional state-centred ways amounts to a scenario of diminishing returns.

- Description: In the context of widening participation, large classes and increased diversity, assessment of student learning is becoming increasingly problematic in that providing formative feedback aimed at developing student writing proves to be particularly laborious. Although the potential value of peer assessment has been well documented in the literature, the associated administrative burden, also in relation to managing anonymity and intellectual ownership, makes this option less attractive, particularly in large classes. A potential solution involves the use of information and communication technologies to automate the logistics associated with peer assessment in a time-efficient way. However, uptake of such systems in the higher education community is limited, and research in this area is only beginning. This case study reports on the use of the Moodle Workshop module for formative peer assessment of students’ individual work in a first-year introductory macro-economics class of over 800 students. Data were collected through an end-of-course evaluation survey of students. The study found that using the feature-rich Workshop module not only addressed many of the practical challenges associated with paper-based peer assessments, but also provided a range of additional options for enhancing validity and reliability of peer assessments that would not be possible with paper-based systems.

- Description: South Africans today live not only with the memory of the racial injustices of the past, but also with present injustices that are a consequence of that past. How should white South Africans live with these past and present injustices? On recognition of the racial injustices of the past and of the continuation of forms of white privilege today, involvement in ongoing anti-racist struggles seems to be an appropriate way for white South Africans to respond to past and present injustices. However, some discussions of the way in which white privilege operates and is perpetuated in post-segregationist societies suggest the need for caution with regard to white involvement in anti-racist struggles, arguing that some of the ways in which white people involve themselves in apparently anti-racist work actually result in the perpetuation rather than the erosion of white privilege. This article explores concerns about the intractability of white privilege while also ultimately defending the appropriateness of white involvement in anti-racist struggles.

- Description: The controversy around the inclusion of zero in the number system has been widely documented. Influential mathematicians in various ancient cultures did not accept zero as a number. The idea of the empty set was too abstract and they could not conceptualise division by zero. Surprisingly, understanding of the concept is still a matter of concern today. In spite of expansive reports on and recommendations for developing conceptualisation of the concept, learners and teachers still experience problems similar to those that ancient mathematicians struggled with. The study was initiated by an observation of Grade 7 learners' inability to solve the problems 4 × 0 and 0 ÷ 7 effectively or at all. I investigated why Grade 3 to 6 learners and mathematics teachers on a BEd (in-service) course and an accredited ACE course experience problems with the concept of zero. I was especially interested in the understanding of multiplication and division by zero. I investigated teachers' knowledge of zero's characteristics as a number, the history of zero and how they teach the concept, in order to support my assumptions. The data production process was performed over a period of two years. It involved a multi-case opportunity sample approach embedded in the empirical field that formed the backdrop of my involvement as mathematics education specialist in schools in the Western and Eastern Cape. The interpretative orientation of the study allowed me to conduct inquiries that served to confirm or challenge my assumptions and enabled me to construct generalisations that depict learners' and teachers' knowledge construction. The qualitative data analysis informed the presentation and discussion of the findings. The single most important message conveyed to readers of this study is that the value of zero as a number, its importance in the number system, its properties and its behaviour in calculations, should not be underrated. Teaching of this abstract concept requires competent teachers who are able to mediate understanding in the most effective and innovative manner. Professional development programmes should orchestrate this competence and curriculum developers and textbook authors should acknowledge the significance of learning and teaching the concept of zero.

- Description: Pharmacists as members of health care teams, have a central role to play with respect to medication. The pharmaceutical care and cognitive services which pharmacists are able to provide can help prevent, ameliorate or correct medication-related problems. There are however many barriers to the provision of these services and one of the barriers commonly cited by pharmacists is the lack of remuneration for their expert services. The aim of this study is to ascertain if patients in South Africa are willing to pay for pharmacist-provided services which may reduce medication related problems, and thereby determine the perceived value of the pharmacist-provided services, by patients. The study will also seek to determine factors that influence willingness to pay (WTP), including financial status, gender, race, age and level of education. In addition the perceived value of the pharmacist‘s role in patient care, by third party payers (SA Medical Aid providers) and their WTP for pharmacist-provided services (such as DSM) on behalf of patients through their monthly premiums will also be investigated. The study was conducted as a two-phase process: the first phase focused on the opinions of patients and the second phase on the medical aid companies. In phase-1 a convenience sample of 500 patients was recruited by fifty community pharmacies distributed throughout the nine South African provinces. Data collection, consisting of telephonic administration of the questionnaires, was conducted and the survey responses were captured on a Microsoft Excel® spreadsheet. All the captured information was analyzed using descriptive statistics, box and whisker plots, analysis of variance (ANOVA) and regression analysis. In phase-2, medical aid schemes that are registered with the Council of Medical Schemes (CMSs) of South Africa were included in this research. A fifteen point questionnaire was completed electronically via e-mail by willing medical aid participants. Data was analyzed using descriptive statistics only. Only 233 or 88.6 percent, of the 263 participating respondents, were willing to pay at least one rand towards pharmacist-provided services. On average respondents were willing to pay R126.76 as out-of-pocket expenses. Respondents‘ WTP increased as the risk associated with medication-related problems was reduced due to pharmaceutical care intervention. Of the 263 respondents who took part in this research, fifty percent were willing to pay at least R100 for a risk reduction of 30 percent, R120 for a 60 percent reduction and approximately R150 for a greater than 90 percent risk reduction. It was also found that the respondents‘ willingness to pay was influenced by their age, earnings, racial grouping, employment status, medical aid status and their level of satisfaction with pharmacist-provided care services. Of the thirty-one open medical aid schemes only eight (25.8 percent) participated in the study. Findings indicate that all the participating medical aid respondents were unwilling to pay for pharmacist-provided care services, although they perceived pharmacists as very influential healthcare providers and as having a significant role to play in reducing medication-related problems. In conclusion it was found that majority of participants were willing to pay for pharmacist-provided services directed towards reducing risks associated with medication-related problems. Until pharmacists are able to prove pharmaceutical care‘s utility and cost-effectiveness to third-party payers, pharmacists must look to the patient for reimbursement.

- Description: Based on ringing data from the Western Cape, Underhill et al.(1995) demonstrated that there was a bimodal distribution of wing-length measurements in the Lesser Honeyguide Indicator minor, and they described the timing of wing-moult in this region. Hanmer (1997) reported similar results for Lesser Honeyguides from Mozambique and Malawi. This species remains poorly studied, and we have examined size dimorphism and wing moult for a sample of birds from the Eastern Cape region: 44 museum specimens from the Albany Museum (Grahamstown), East London Museum and the Ditsong Museum (formerly Transvaal Museum, Pretoria), together with ringing data for 94 birds. Wing-length of both museum specimens and ringed birds was measured in the standard manner (maximum chord); weight to the nearest 0.5 g was recorded with a Pesola spring balance. Each bird was checked for wing moult, which was recorded as 0 for an old feather and 5 for a fully grown new feather (de Beer et al. 2001). These moult scores were converted to percentage feather mass grown using a primary feather mass index, Passer9 (Bonnevie 2010a), for analysis using the model of Underhill and Zucchini (1988), as implemented in R (Erni et al. in press), with the data subsampled to prevent non-moulting birds from biasing the estimates (Bonnevie 2010b).

- Description: Psychobiography is a qualitative approach to exploring and understanding the life story of an individual through the lens of psychological theory. The application of theory is typically conducted on the finished lives of well-known or enigmatic people. This study explores and describes the psychological development across the lifespan of Winston Leonard Spencer Churchill, by applying the Individual Psychology of Alfred Adler. Winston Churchill voted the greatest Briton of the twentieth century, was an author, painter, adventure, soldier, politician and Prime Minister that led the United Kingdom during World War Two. Extensive data has been examined in this work to ensure an accurate description of Winston Churchill‘s life. Alexander‘s model of identifying salient themes was used to analyse the data within a conceptual framework derived from the theory. Churchill‘s difficult childhood motivated him to succeed, his passion for the nation of Britain and his dislike of the Nazi regime meant that Churchill was always abreast with current affairs, anticipating every possible scenario of attack. When the time came to fight the Nazi‘s Churchill was ready to die for his country. The research findings highlight Churchill‘s ability to rise above his childhood stigmas and surpass all expectations and so cementing his name into the history of a country he loved and a democratic world he hoped for. Alfred Adler‘s Individual Psychology proposes that an individual‘s potential weaknesses can be used as a means to strive and achieve greatness within their sphere of influence.

- Description: Winter rotational cover crops (WRCC) are often used to boost soil fertility and plant nutrition. However, selection and use of WRCC for soil physical improvement is usually overlooked. The objective of this study was to determine the effects of WRCC on soil strength, aggregate stability and water conservation of a hardsetting soil. The soil physical properties were determined after four rotations of growing monocultures of vetch (Vicia dasycarpa cv. Max), lupin (Lupinus angustifolius cv. Tanjil) and oats (Avena sativa cv. Sederberg) and after two rotations of growing bicultures of oats (Avena sativa cv. Pallinup) and vetch (Vicia dasycarpa cv. Max) across two soil layers, 0 to 15 cm and 15 to 30 cm. The individual WRCC and a weedy fallow constituted the treatments in the monoculture study whilst in the biculture study the various combinations of WRCC namely; 90% oat plus 10% vetch (O90V10); 70% oat plus 30% vetch (O70V30) and 50% oat plus 50% vetch (O50V50) and a weedy fallow constituted the treatments. After four rotations with cover crop monocultures, oats significantly (P ≤ 0.05) reduced penetration resistance (PR) whilst vetch increased PR in both soil layers compared to the weedy fallow control. The effect of the biculture treatments was only experienced within the 15 to 30 cm depth. The treatments O50V50 and O70V30 increased the PR compared to the control. The WRCC in monoculture significantly increased the soil aggregate stability relative to the control in both soil layers. Vetch, lupin and oats resulted in a 41.7%; 20.4% and 15.7% increase in MWD in the 0 to 15 cm soil layer and 47.2%; 44.2% and 39.7% in the 15 to 30 cm depth, respectively. An increase in aggregate stability was associated with increased macro-aggregation. Under the biculture, WRCC slightly increased, non- significantly, the aggregate stability. Both hot water and dilute acid extractable polysaccharides showed no significant correlation with aggregate stability in the two studies. Oats monoculture resulted in a significant difference (P ≤ 0.05) on cumulative infiltration compared to the control. However, after 2 h vetch and lupin showed no significant difference from the control on cumulative infiltration. Oats resulted in a 7.8% increase in final infiltration rate (FIR) whilst vetch and lupin reduced FIR by 9% and 16.7% respectively, compared to the control. Bicultures of oats and vetch significantly (P ≤ 0.05) increased cumulative infiltration compared to the weedy fallow control. A similar significant increase in FIR was also observed under bicultures. The treatments O50V50; O90V10 and O70V30 resulted in a 163.3%; 113.3% and 105.4% increase in FIR respectively, compared to the control. Cover crop monocultures significantly (P ≤ 0.05) increased plant available water (PAW) compared to the weedy fallow, with vetch, oats and lupin resulting in a 28.3%; 22% and 23.9% increase respectively, in PAW. However, no significant differences were observed on PAW after two rotations with bicultures. Compared with winter weedy fallow, WRCC improved most of the soil physical properties under study, with the most suitable results expected under bicultures compared to monocultures. Under CA, selection of WRCC like oats, vetch and lupin, one should therefore take into consideration their effects on soil physical properties as a selection criterion and not biomass and fertility alone.
