- Description: β-N-methylamino-L-alanine (BMAA) is a non-proteinogenic amino acid associated with human neurodegenerative disease. Due to the cosmopolitan nature of cyanobacteria, detection of BMAA in cyanobacteria has caused concerns about human exposure risk. This study was therefore based on the hypothesis that BMAA poses a health risk to humans either by direct ingestion or by indirect exposure to BMAA from a cyanobacterial source via a freshwater food chain. A validated gas chromatography-mass spectrometry (GC-MS) BMAA analysis method and a confirmatory liquid chromatography-mass spectrometry (LC-MS) method, with improved sensitivity, were developed in addition to a LC-MS/MS method for analyte confirmation. These methods were used to quantify BMAA in South African cyanobacteria, isolated from various potable water reservoirs. The majority of the isolates tested, contained BMAA. Possible human exposure by direct consumption of BMAA released from cyanobacterial blooms was investigated by the development of a robust solid phase extraction (SPE) method used for BMAA concentration and quantification in raw and treated tap water. Despite the use of the SPE method that facilitated the concentration of BMAA from large quantities of water, no free dissolved BMAA was detected in raw or processed fresh water. The fate of exogenous BMAA was therefore investigated firstly by evaluating the efficacy of standard water treatment processes employed in South Africa and secondly by investigating the possibility of BMAA bioaccumulation and biomagnification in aquatic food chains. Standard water treatment processes proved highly efficient at removing free dissolved BMAA, explaining the absence of BMAA in treated tap water. However, the cause of the BMAA absence in raw potable water remained unknown. Uptake of BMAA by model aquatic organisms was investigated in controlled experiments. BMAA uptake was documented in both Ceratophyllum demersum and Daphnia magna, however, BMAA-protein association and biomagnification were not observed in D. magna. BMAA had an inhibitory effect on the oxidative stress enzyme acitivties of both organisms tested (as well as human S9 extracts), resulting in accumulation of detrimental reactive oxygen species (ROS) in the cells. Exposure of crop plants to BMAA in controlled experiments resulted in BMAA uptake, protein association, and subsequent inhibition of the antioxidative enzyme activities. However, BMAA was detected in neither free nor protein-associated form in natural crop plants irrigated with known BMAA-containing bloom water. Post-mortem liver samples of Clarias gariepinus (Catfish) and Crocodylus niloticus (Crocodile), from a natural fresh water ecosystem that experienced frequent cyanobacterial blooms, contained both free and protein-associated BMAA. Higher BMAA concentrations were found in crocodile liver samples compared to fish liver samples, strongly suggesting biomagnification from one trophic level to the next. BMAA concentrations corresponded to crocodile age. This is the first report of bioaccumulation and biomagnification in two trophic levels in a fresh water ecosystem. These findings strongly suggest possible human exposure via aquatic food chains of cyanobacterial origin. Direct BMAA exposure via drinking water is not plausible due to the efficiency of standard water treatment processes to remove BMAA. The use of raw water for agricultural and recreational use, however, remains a problem. The development of management strategies as well as daily tolerable levels for BMAA is urgently required.

- Description: Cryptosporidiosis is an infection caused by Cryptosporidium; a protozoan parasite that infects the gastrointestinal tract. The infection is of major public health concern in both developed and developing countries. Faecal samples were collected from 160 in-patient adults, with complaint of diarrhoea, admitted at Victoria hospital in Alice, Nkonkobe Municipality. Twenty apparently healthy subjects were included as controls. All diarrhoea positive patients were interviewed to record socio-demographic information, water supply and animal contact. Initial screening was carried out by microscopy and ELISA to detect positive Cryptosporidium. Genomic DNA was extracted from microscopically positive samples and a PCR reaction was perform to amplify the (18S) SSUrRNA gene for further identification and epidemiology of Cryptosporidium. Data were analysed using Pearson‘s χ2 and Fisher‘s exact test to assess the univariate association between Cryptosporidium infection and the possible risk factors. Of the 180 subjects screened for cryptosporidial infection, Cryptosporidium antigen was detected in 122 giving an overall prevalence of 67.8 percent. In HIV-positive diarrhoea patients, prevalence increased with ages; between 31-43 (mean age 36.5 yr) and 70-82 (mean age 75.8 yr) had a higher prevalence (100 percent) of the antigen than 18-30 (mean age 23.2 yr) and 83-95 (mean age 88.8 yr) (50.0 percent) in HIV-positive diarrhoea patients (P > 0.05). In HIV-negative diarrhoea patients, prevalence was highest in the 18-30 (mean age 23.2 yr) (87.5 percent) and least (35.7 percent) in those aged 83-95 (mean age 88.8 yr) (P > 0.05). Cryptosporidium antigen was higher in females than in males. Of 115 females (mean age 46.7yr) who participated in the study, antigen was detected in 90 (78.2 percent) against 32 (71.1 percent) of 45 males (mean age 42.6yr). None of the 20 apparently healthy control subjects was found to be infected with Cryptosporidium. Cryptosporidium was detected in 27 HIV-positive and 97 HIV-negative diarrhoea patients by any one of the techniques. Antigen detection by ELISA 14 showed the highest positivity 96 (76.8 percent) in HIV- negative and 26 (74.3 percent) in HIV- positive diarrhoea patients. PCR detected eighty-nine (71.2 percent) cases in HIV-negative and 23 (65.7 percent) in HIV-positive patients with diarrhoea. Only 13 (37.1 percent) HIV-positive and 34 (27.2 percent) HIV-negative diarrhoea patients were found positive for Cryptosporidium by modified ZN. No significant difference was observed in sensitivity of antigen detection by ELISA and PCR (96.9 percent) in HIV-negative diarrhoea patients, respectively. Specificity of the staining technique was 88.9 percent in HIV-positive and 96.6 percent in HIV-negative diarrhoea patients. No significant difference was found in specificity of antigen detection by ELISA and PCR in HIV-positive and HIV-negative diarrhoea patients, respectively. Positive predictive value of ZN staining in both HIV-positive and HIV-negative diarrhoea patients (92.3 and 96.9 percent) was statistically higher than ELISA and PCR. No significant difference was observed in negative predictive value of ZN technique for detection of Cryptosporidium between HIV-positive and HIV- negative diarrhoea patients. Differences found in prevalence rates due to water source, suggest that the high infection rates of specific groups are associated with their exposure to the contaminated water supply. The results indicate that Cryptosporidium infection is highly prevalent in adult faecal specimens in the Nkonkobe Municipality, an indication of active infection that is likely to emerge as major human pathogen in this location due to socioeconomic changes which favour transmission. However, sequencing analysis is required to differentiate between Cryptosporidium genotypes in the various outbreaks

- Description: Taking cognisance of the increasingly important role that copreneurial businesses play in national economies, the unique challenges that they face, and the lack of research attention given to such spousal teams, the purpose of this study was to contribute to the more effective functioning of copreneurships in South Africa by identifying the factors that impact on their success. Consequently, the primary objective of this study was to investigate the factors that influence the Perceived success of copreneurships in South Africa, as well as the conditions required for the effective and harmonious functioning of such spousal partnerships. This study seeks to incorporate previous findings and studies on team effectiveness and spousal relationships into a comprehensive conceptual model. After conducting a comprehensive literature study, as well as examining the different teamwork models proposed and the study by Farrington (2009), it became clear that successful teams have validated their proficiency with regard to two types of factors, namely, relational-based and organisational-based factors. Within these two categories of factors, 14 independent variables were identified and hypothesised to influence the measures of effectiveness of copreneurships, namely the dependent variable Perceived success; and the intervening variable Financial performance. All of the factors in this study were clearly defined and operationalised. Reliable and valid items sourced from Farrington’s (2009) measuring instrument, as well as several measuring instruments used in other studies, were used in the operationalisation of these factors. In addition, several items were self-generated from secondary sources. Respondents were identified using the convenience snowball sampling technique, and a structured questionnaire was made available to them. The data gathered from the 380 usable questionnaires was subjected to various statistical analyses. The validity and reliability of the measuring instrument was confirmed by means of an exploratory factor analysis, and Cronbach-alpha coefficients were calculated for this purpose. The original intervening variable Financial performance could not be confirmed as originally intended in the conceptual model. Instead, Financial performance split into v two separate variables which were named Financial performance and Growth performance. The original dependent variable Perceived success was confirmed by the factor analyses. The relational- and organisational-based factors could not be confirmed as originally intended in the conceptual model. Instead, seven new relational- and seven new organisational-based factors emerged, and where necessary these factors were renamed. The primary statistical procedure used to test the significance of the relationships hypothesised between the independent and dependent variables in this study, was Structural Equation Modelling (SEM). Owing to the sample-size restrictions, the conceptual model could not be subjected to SEM as a whole. Instead, seven submodels were identified and subjected to further analysis. The following independent variables were identified as influencing the dependent and intervening variables in this study: • Spousal relationship • Commitment to spouse • Equal status • Commitment to the business • Emotional attachment • Non-family involvement • Personal needs alignment • Leadership • Competencies • Internal context In order to investigate the influence of the various demographic variables on the intervening and dependent variables, an Analysis of Variance (ANOVA), Multiple Linear Regression analysis and t-tests were performed. How leadership occurs in a copreneurial business, the tenure of the business, the location of the business, the status of the copreneurship, the level of spousal involvement in the business and the vi number of employees were found to have an influence on the intervening and dependent variables of this study. By empirically investigating copreneurships, this study has added to the limited amount of family business literature on these complex partnerships. By way of the conceptual models developed in this study a significant contribution has been made towards understanding the factors influencing the success of copreneurships. As a result, this study presents recommendations and suggestions to assist couples in managing their copreneurships in such a way as to nurture their marriage relationships and at the same time enhance the performance of their businesses.

- Description: This study explored the balancing out of the rights associated with terrorist and counter-terrorist attacks by using descriptive case studies of the US 9/11 attacks; and the counter-terrorist attacks on Afghanistan and Iraq. The research was conducted within a critical theory paradigm, drawing on the ideas of Habermas and other Critical Theorists. The research design was influenced by the securitive and ideological nature of the topic and it was decided that an extensive review of literature would be more suitable than a field study. A small number of interviews added to the richness of the data. Human rights, needs and international relations were investigated to serve as a theoretical starting-point for the study (Chapter 2). The case studies were subsequently explored against the background of this theoretical approach. This thesis therefore assessed the impact of human rights law on terrorism and counter-terrorism attacks under the Human Rights Act (1998). It considered how the provisions of the Human Rights Act have influenced the formulation and interpretation of anti-terrorism laws, and it examined the role of the judiciary in adjudicating disputes between the individual and the state. It further discussed human needs and the progress on human rights, terrorist attacks, as well as counter-terrorism attacks. Extensive data was gathered on the 9/11 attacks, and it was concluded that these attacks fall within the definition of crimes against humanity under international human rights jurisprudence. To bring about a truly secure world we must adopt a new paradigm that shifts priority to the security of the individuals and of communities to achieving human security, the honouring of human rights, and respect for the rule of law. This will obviously require a renewed commitment by all individuals and a shared sense of responsibility for all people, all over the world. What we need now is a major course correction – a new iii A. Fabbriciani approach which begins with a broader understanding of what defines human rights and the rule of law (Wilson, 2007). The study also focuses on counter-terrorist attacks in Afghanistan and Iraq (Chapters 3 and 4). It was shown that counter-terrorist attacks had an effect on the global economic system and development policies, which have been dominated by ideological strategies for many years. However, resistance has come from Islamic states, which have realised that new-liberal economic practices are incompatible with their theological and economic traditions. This has caused a situation to rethink global development programmes by political leaders, and to move away from new-liberal schemes towards true global development strategies. One of the main findings of the study was that the crimes of persecution and torture on the basis of political or religious views have been perpetrated by both parties, namely Al-Qaeda, and the US and its allies. It has been shown that the explored acts of terrorism and counter-attacks represent crimes against humanity, as defined by the relevant provisions of international law.

- Description: Historically, the two species of Cape hakes Merluccius capensis and M. paradoxus off South Africa were commercially exploited exclusively by demersal trawling. In 1994, hake-directed demersal longline was introduced on an experimental basis, and in 1998 was initiated as a commercial fishing sector. The effect of a combined fleet composed of both trawlers and longliners on the Cape hake resource is not fully understood. Analysis of fishing intensity and catch-rate data revealed that the highest catch rates were found around the 400m and 500m isobaths for the trawl and longline fisheries respectively. Catch rates from both fishing sectors were also noted to be higher over sediments with a sand component. Differences between areas of the highest fishing intensity and highest catch rates were noted. In addition to other factors, it is suggested that a ‘friction of distance’ effect applies — vessels will trade-off higher catch rates with the increased costs associated with fishing in deeper waters.

In addition to other factors, it is suggested that a ‘friction of distance’ effect applies — vessels will trade-off higher catch rates with the increased costs associated with fishing in deeper waters.

- Description: Six indicators were investigated for South African sardine Sardinops sagax and anchovy Engraulis encrasicolus: mean length of catch, length-at-50% maturity, total mortality, exploitation rate, ratio of bycatch, and centre of gravity of commercial catches. Sardine length-at-50% maturity is the most promising as a descriptive indicator because it is positively correlated with population size for an extensive time period (1953–2005). The remaining indicators were limited by shorter data-series (1984–2005). However, mean length of catch, ratio of bycatch and exploitation rate were found to be useful when considered in conjunction with other indicators. The centre of gravity of commercial sardine catches has shown a significant eastward shift from the West Coast, whereas that of anchovy has remained off that coast. Ratio of bycatch indicates that school composition is a reliable descriptive indicator of relative abundance in the two species. Fewer indicators for anchovy were useful, which is attributed to this species’ flexible life-history pattern.

- Description: Smallholder irrigation schemes (SIS) in South Africa have performed poorly and failed to achieve the development objectives of sustaining rural livelihoods by increasing crop production and income. Limited knowledge of crop production among farmers is one constraint to improved crop productivity and, yet little research has been carried out to relate agronomic practices to productivity. This study was aimed at identifying strategies to improve the productivity of maize-based smallholder irrigated cropping systems in South Africa, using Zanyokwe irrigation scheme (ZIS) in the Eastern Cape Province as a case study. The research design was emergent, developed progressively as influenced by the progressive analyses that were made. The research work involved two main phases: exploratory studies and refinement on-farm experiments for testing technologies as informed by the exploratory studies. Exploratory studies were aimed at describing farmer crop production practices in major crop enterprises and identifying and prioritizing major agronomic yield constraints. Findings indicated that the overall performance of the cropping systems was poor as evidenced by low overall yields of < 25% of the potential in maize and butternut. Poor management of weeds, soil fertility, plant populations and water, late planting and poor cultivar choice were the most important yield constraints. The average cropping intensity achieved by farmers was only 48%. New hybrids yielded 50 - 65% higher grain than the cultivars commonly grown by farmers. However, farmers favoured their traditional cultivars, as they preferred green maize production as opposed to dry grains. As a result of these findings, focused research was designed on options for iii improving green maize production, soil fertility, crop stand and weed management in crop production. On-farm trials were, therefore, designed to (1) compare the response to nitrogen (N) rate of direct seeded and transplanted maize; (2) evaluate comparative performance of direct seeded and transplanted green maize under farmer management, and to work out the economics of transplanting; (3) investigate the effects of row spacing and atrazine dosage on weed dynamics maize yield; (4) determine the effects of inter-row spacing and plant population on weed dynamics and maize yield; and (5) investigate the effects of pre-plant weed control, N rate and plant population on weed dynamics and butternut yield. Maize transplanting improved crop stand, had earlier maturity and yielded higher at lower N rates compared to direct seeding for both green and grain maize. Total costs that varied were higher by R3 565 ha-1 for transplanted maize compared to direct-seeded maize, but the net benefits from transplanting were also much higher by R8 773 ha-1. Farmers favoured transplanting, citing bigger cobs, early maturity and the absence of seedling damage by birds, when maize was transplanted. However, a follow-up survey conducted during the subsequent year indicated that five of the six farmers abandoned transplanting, citing shortage of labour and high cost of commercially produced seedlings. It was concluded that transplanting is unlikely to be adopted unless the labour intensiveness of manual transplanting can be solved. Increasing atrazine dosage from a third of the label recommended dosage (LRD) and reducing row spacing from 90 to 45 cm resulted in an increase in weed mortality. A 100% kill of annual broadleaf weeds was possible while iv perennial grasses and the annual broadleaf weed, Oxalis latifolia, could not be controlled even at the LRD. However, improved weed mortality with increase in atrazine dosage and/or narrow rows did not translate into improved maize productivity. In butternut, pre-plant weed control resulted in a six-fold decrease in weed biomass and a 100% increase in fruit yield. These findings demonstrated the possibility of incorporation of reduced herbicide dosages and narrow rows to achieve adequate weed control and optimise on maize yields in smallholder farming systems. The results also suggested that pre-plant weed control is one of the pre-requisite to successful butternut production in SIS in South Africa. Increasing maize population from 40 000 to 60 000 plants ha-1 resulted in a 30% grain yield increase, but decreased length of cobs. Row spacing had no effect on maize yield at 40 000 plants ha-1, but at 60 000 plants ha-1 45 cm rows resulted in 11% higher grain yield (12 547 kg ha-1) than 90 cm rows (11 288 kg ha-1). Butternut yield increased significantly (p < 0.01) with increase in plant population and N rate. The optimum butternut population and N rate were estimated at 25 000 plants ha-1 and 120 kg N ha-1, respectively. Pre-plant weed control in butternut resulted in a six-fold decrease in weed biomass. Increasing butternut planting density from 10 000 to 30 000 plants ha-1 decreased weed biomass by 47%. No marketable fruits were obtained when planting was done without prior weed control. This result suggest that application of non-selective herbicide before planting is one technique that can be used by farmers as part of integrated weed management to give the crop a competitive advantage in the early growth stages before the plants start to produce vines. Yield increased significantly (p < 0.01) with increase in plant density and N rate. The optimum plant density and N rate were estimated at 25 000 plants ha-1 and 120 kg N ha-1, respectively. These findings emphasise the need to take into consideration production practices by farmers as a basis to build up skills in the management of crop enterprises and the farm as a viable business in any efforts to improve on the performance of SIS in South Africa. Future research should concentrate on labour-saving sustainable production technologies for SIS in South Africa.

- Description: The importance of SME family businesses is evident in society. Coming out of a recession, the innovation, labour absorption and employment creation capabilities of SMEs and family businesses globally, and in emerging economies with high levels of unemployment and poverty, is incredibly important for environmental sustainability and societal harmony. Good governance is empirically proven to improve long-term sustainability of organisations, and poor governance is linked to the demise of many businesses – large and small, family and non-family businesses alike. This research, by means of a thorough literature review of family business and governance, and a single in-depth case study, identifies the components of SME family business governance in a contextual setting in South Africa. The literature review defines SMEs, family businesses and corporate governance. It reviews the nuances of family businesses that make them distinctive from non-family businesses, the models of family businesses that have been developed over time, the approaches to corporate governance, corporate governance codes of conduct, and family business governance models, as well as the components and dynamics of family business governance. The qualitative case study approach adopted enables the in depth contextual identification and exploration of the dynamics of family business governance. Empirical data collected from interviews, observations and reports are analysed using triangulation and pattern matching logic to ensure validity and reliability. Empirical findings are discussed with reference to the literary research findings, integrating literary and empirical findings, and resulting in the development of a conceptual model of family business governance, an SME family business governance structures model, and an SME family business authority delegation model. Governance is defined as the manifestation of the intent of the founder/owners of the business. Governance is manifest in structures, strategies, policies, procedures, relationships and performance. The reciprocity of transfers and outputs between the family business systems, the family business and its contextual environment is reflected in the performance of the business; which in turn is a reflection of the governance of the family and the family business. The study concludes with the importance of the family and its cohesion and harmony, and the impact it has on synergy, unity and harmony in the business. The study also finds that governance is strategic leadership, and that efficient and effective governance leads to synergies between the family, the family business and its contextual environment that when harnessed and directed towards a vision, can produce unimitable competitive advantages for the family firm.

- Description: Literature has tended to be cut from the moorings of its authorial origins under the influential literary criticism of the past forty years. This thesis is an attempt to re-moor a work of literature to its authorial origins; particularly a work of literature in which the author-poet‘s self-referential markers are so overtly and persistently present as is the case in Hesperides and His Noble Numbers. Although there is a significant overlap between the real-life Herrick and the Hesperidean Herrick, the two figures cannot be regarded as identical. Instead, Herrick‘s deployment of specific genres and not of others, his chosen conventions for ordering a collection of miscellaneous poems, and his adoption of certain conventional poetic stances provide him with a semi-fictionalised way of declaring who he understands himself to be and how he wants himself to be understood. At the same time, the rich classical mythological associations of Herrick‘s title, Hesperides, declare his status as an inheritor of the classical literary tradition, whose hallmark during the Renaissance was the melding of classical, Christian and secular associations into new and complexly polyvalent literary works. For example, Herrick‘s appropriation of the classical mythological figure of Hercules provides him with both a narrative way and an allegorical way of reconciling the so-called secular, or profane poetry of Hesperides with the so-called religious, or divine poetry of Noble Numbers. In Noble Numbers, Herrick reveals new facets of his self-presentation to the reader, whilst also making explicit the theological congruencies between the two works. Herrick‘s religious self-presentation demonstrates his expansive scholarly interests, as well his instinct to include, rather than to exclude, the religious beliefs of others within his syncretistic sense-of-self. Finally, the placement of Noble Numbers after Hesperides is not a signal that Herrick privileged the former, or took his religion less seriously than he did his love for classical poetry, but rather that in Herrick‘s understanding of his world, man‘s fleeting glimpses of God in the secular sphere give way to a fuller comprehension of Him in the divine sphere.

- Description: Print newspapers in South Africa are the oldest formal mode of news and information dissemination but which has come under tremendous pressure with the advent and spread of technological innovation involving information communication infrastructure and processes, but specifically the internet. The main challenge facing print newspapers in terms of circulation growth of print and advertising revenue is speed to market. The internet has not only provided a new avenue for news and information dissemination but has the distinct advantage of tremendous speed to deliver news and information to readers. Meanwhile, print newspapers whose production is still almost entirely dependent on traditional structures, processes and physical mode of delivery are battling to stay afloat as the chase for readers' attention is gaining more ground on digital platforms. This new competition landscape has now cast focus fully on traditional print media‟s production processes competency levels as well as their suitability for the nature of competition posed by digital news platforms. The processes involved in the production of a print newspaper can be described as hybrid (Davis and Heineke. 2005: 220) in that they involve different types of processes at different stages to produce the final product. The focus of this study at Avusa Media (Port Elizabeth) was on the post production processes involving the printing and distribution of printed newspapers with the objective of gaining an understanding of the extent and impact of the information technology advancement in the post production phase of printed newspapers. v In pursuing the goal, the case study research followed a phenomenological paradigm involving exploratory and descriptive research processes as described by Yin (1994) in Collis and Hussey (2003: 69) and Clifford Geertz (1973) in Babbie and Mouton (2005: 272) The research found that the traditional business structure for printed newspapers is increasingly becoming unviable due to poverty of technological innovation in critical parts of the production value chain; namely post production processes that encompass printing and distribution of printed newspapers. The research established and revealed that while there are some technological innovations and advances in the print newspaper publishing industry value chain worldwide, they are not only severely limited and disjointed but are also seemingly moving apart rather than towards consolidation in terms of the speed to market need faced by print newspaper publishers.

- Description: The Constitution Act, 108 of 1996 declares that: 'in the Republic, government is constituted as national, provincial and local spheres of government that are distinctive, interdependent and interrelated". Section 41(1)of the above Constitution further states that there shall be cooperation, mutual trust and good faith between these three spheres. They should inform and consult one another on matters of common interest, co-ordinate their legislation, and adhere to agreed procedures. In addition, it is expected that acts of Parliament should establish structures and institutions to promote and facilitate intergovernmental relations, and provide mechanism and procedures to facilitate settlement of intergovernmental disputes. In view of the above, it is evident that co-operative government can be regarded as one of the cornerstones of the new constitutional dispensation in South Africa and intergovernmental relations can be regarded as practical instrument for ensuring co-operative government in the delivery of services by the three spheres of government. The study therefore seeks to assess the impact of intergovernmental relations on service delivery in the Department of Cooperative Governance and Traditional Affairs in Eastern Cape Province from the year 1994-2009. It also attempts to show the importance of intergovernmental relations to service delivery especially in integrated development planning, co-operation and co-operation and co-ordination of policies and plans.

In addition, it is expected that acts of Parliament should establish structures and institutions to promote and facilitate intergovernmental relations, and provide mechanism and procedures to facilitate settlement of intergovernmental disputes. In view of the above, it is evident that co-operative government can be regarded as one of the cornerstones of the new constitutional dispensation in South Africa and intergovernmental relations can be regarded as practical instrument for ensuring co-operative government in the delivery of services by the three spheres of government. The study therefore seeks to assess the impact of intergovernmental relations on service delivery in the Department of Cooperative Governance and Traditional Affairs in Eastern Cape Province from the year 1994-2009. It also attempts to show the importance of intergovernmental relations to service delivery especially in integrated development planning, co-operation and co-operation and co-ordination of policies and plans. "The assessment of the impact of intergovernmental relations on service delivey in the Department of Co-operative Governance and Traditional Affairs in the Eastern Cape Province (1994-2009)".

- Description: People without private transport are dependent on public transportation. Public transport, particularly minibus taxis, is the most popular mode of transport in the Northern Areas of Port Elizabeth. The objective of the minibus taxi industry is to provide public transport to minibus taxi commuters in an economically, reliable and safe manner. The focus of this case study was to explore and determine the views of minibus taxi commuters who utilised minibus taxis as a form of public transport, as well as the views of minibus taxi drivers in terms of adhering to road safety requirements on Stanford Road in Port Elizabeth. The literature survey revealed that transport in South Africa has had a political dimension arising from the Group Areas Act 41 of 1950. One consequence of this Act, which imposed residential segregation on the country, was that poor black commuters were forced to live far out of town, forcing them to travel long distances to places of work and commercial centres, with a commensurate increase in transport costs. Data was collected by means of two structured questionnaires which were administered to minibus taxi drivers and minibus taxi commuters to explore their views and experience of road safety on Stanford Road in Port Elizabeth. A discussion on the minibus taxi industry, minibus taxi associations and law enforcement agencies in Port Elizabeth, as well as the sustainability of the minibus taxi industry, followed in Chapter Three. Through this case study, valuable insight was gained regarding the minibus taxi industry and road safety in Port Elizabeth. Finally, recommendations to improve road safety were made.

- Description: The purpose of this study was to explore and identify factors that either facilitate or inhibit individuals volunteering for HIV-testing. The target group was comprised of Xhosa first-language construction workers in a company with an HIV/AIDS workplace policy and programme. This programme provides basic education and awareness about HIV/AIDS. This education includes information about where to access voluntary counselling and testing (VCT) services. Interpretive qualitative research was undertaken in order to explore the beliefs, perceptions and intentions of the target group in regard to the utilisation VCT services. Data was collected using an unstructured interview guide. The data was analysed using Tesch’s approach to content analysis. Concerns about validity and reliability were engaged throughout the research process and supported further by using researcher reflexivity and an independent researcher. The independent researcher analysed data separately and only after discussion and consensus being found between the two researchers were final categories and codes agreed upon and data analysis considered complete. Findings revealed that an HIV/AIDS workplace programme has a positive impact on the health-seeking behaviour of workers in the construction company used in this research. Respondents knew how HIV/AIDS is transmitted, how to prevent transmission and where to find HIV-testing treatment and support. In this case HIV-testing services can easily be accessed further facilitating respondents volunteering for HIV-testing. It was also found that family, friends and churches support HIV-testing behaviour by providing education, guidance and support to respondents encouraging behaviour change. On the other hand, respondents held that community members who had not benefited from an HIV/AIDS workplace programme such as theirs are exposed daily to the devastating effects of HIV leading to AIDS deaths and live in fear of the disease. Debilitating illness and eventual death is equated with an HIV-positive diagnosis which causes community members to believe it is better not to volunteer for HIV-testing than to ascertain one’s HIV-status. The HIV/AIDS workplace policy and xv programme on the other hand is seen to have provided respondents with HIV/AIDS knowledge enabling them to overcome their fear of an HIV-positive diagnosis and to volunteer for regular HIV-testing.

- Description: This research has undertaken two key mandates. One was to develop modifications to the African Catchment Game (ACG), a role playing simulation game, in order to simulate rainfall and water management processes representative of the southern African context. The other was to understand what, if any, learning associated with water management issues had taken place as a result of playing the ACG. The modification process took the form of an action research process. The initial modifications were trialed with South African students as part of their undergraduate Geography course offered at Rhodes University, South Africa. Subsequent modifications were implemented over a five month period with three diverse participant groups, namely Finnish, American and South African participants. An interpretive research orientation was employed in order to analyse both the qualitative and quantitative data that was generated. Pre- and Post-Game Questionnaires were used in order to identify the learning and understanding which the participants constructed as a result of playing the ACG. The Chi-Square Test was also applied to each of the pre- and post- questions to establish statistical significance. Subsequent analysis of these questions identified and traced patters and trends associated with learning and understanding across the three game runs. This research study draws on social constructivism and experiential learning as the dominant education theory that underpins it. Results revealed that for all three game runs learning took place. Participants identified dominant themes and environmental dimensions both before and after playing the ACG. The analysis of these responses indicated a deeper awareness of water as a contributing factor for sustainable economic development while the game runs enabled the researcher to adjust the water availability within each game run until rainfall and water management processes representative of a southern African context were successfully simulated in the last game run.

- Description: The quality control of geometrical coherences and relations in modern automobile production is done by different stationary and flexible measurement systems and strategies. Furthermore, there currently exists possibilities of inline measurements and offline measurements. This project presents the basic research concerning the possibility of a flexible wireless measurement system in modern automobile production, that is able to combine the advantages of both strategies. An investigation of existing measurement techniques was done in order to find a sensor technology, which enables the wireless measurement process. The research project introduces the current location systems and positioning systems. These techniques are compared by a value benefit analysis to expose a suited technology as basis for the measurement system. As result of the value benefit anlysis, the ultrasonic technique was selected for further investigations. The ultrasonic test setup is used to analyze the accuracy of modern sensors and to verify the possibility of a project related integration. The tests are done in different conditions, in order to compare the laboratory application and the industrial application. During the test measurements different physical influencing variables and disturbances occurred. From this research project, it can be concluded that the laboratory application of the system is possible. However, the industrial application is subject to restrictions.

- Description: Discipline in the government schools in South Africa has deteriorated during the past fifteen years. There are many different reasons for that. The aim of this study was to develop a uniform programme of discipline which can be used for application in all ten schools in the Bitou area. To reach this aim, the following procedures were followed: • A study has been done regarding the supporting role of the Bitou 10 foundation in the designing and management of a uniform discipline program. • A summary of the disciplinary problems in government schools has been given with possible reasons why discipline has deteriorated. • A study has also been made of various programs of discipline which have been used in various countries in the past. Certain aspects of those programmes have been used in this study to compile an effective programme of discipline for all the schools in the Bitou area. • Criteria for a positive discipline program have been put together. This study has been done in the Plettenberg Bay area. This area has ten schools which include primary- and high schools, single medium- and double medium schools, multi-cultural and mono-cultural schools and also some schools which have hostels. This study showed that not all schools in the Bitou area follow the same disciplinary programme. This study also makes recommendations on the possible implementing of such a uniform system of discipline. This study does not only show what the role is of the principal and teachers responsible for discipline, but also indicates the role and task of the parents and the community. Research on the application of discipline can never end because new ideas and methods will always be found to create an ideal programme in order to make the process more effective.

In the majority of these conflicts child soldiers are involved in various ways. Judicial problems concerning the prosecution of commanders and leaders of armed groups, irrespective of governmental or not are being solved. Thus, underlying concern is left to the issue of accountability of child soldiers. International, Regional and National protection measures provide for certain judicial standards dealing with children under the age of eighteen. In order to fully understand the difficulties arising from the existence of universal binding measurement dealing with the accountability of child soldiers, one has to be aware of the international, regional and national legislative frameworks. In Sub Saharan Africa, especially in Rwanda, Uganda and the Democratic Republic of Congo, governments face various difficulties, such as the implantation process of international protection measures and ongoing conflicts, making it very difficult to examine the status of accountability measures for child soldiers. States have different minimum ages for accountability for child soldiers. Only a process of international co-operation between governments and non state actors can attempt to deal with the accountability of child soldiers. Not only deterrent, but rather restitution approaches and reintegration programmes should be followed in order to bring justice and achieve results in peace processes.

- Description: This research reviews the challenges and obstacles confronting multinational civil engineering consulting and contracting companies seeking to conduct project developments within Emerging Markets, specifically with regard to the regions of Africa and the Middle East. With the increasing convergence of the global economy towards an interconnected and co-dependant system, the emerging economies of previously underdeveloped parts of the world are now capturing the focus of the civil engineering industry as the primary area of operation. Multinational companies that historically were restricted to construction of the developed world must now adapt and reposition themselves with a footprint in these emerging markets, if they are to take advantage of the changing conditions within the global infrastructure construction industry. For companies historically unfamiliar with operating in Africa and the Middle East, a plethora of potential risks are associated with project development. This research incorporated a substantial literature study that determined a number of critical issues that directly and indirectly influence a company’s ability to complete a project within time and under budget. The literature bank was then tested against the expert opinions of four selected respondents utilising a case study research methodology, as detailed by Yin (1994: 1-17). The respondents represented two selected civil engineering consulting firms, one based in a developed country with an extensive interest in the Middle East, and the other based in an emerging country itself, with operations throughout Africa. The outcome of the research ii highlighted several internal risk factors affecting development in Africa and the Middle East, such as capacity, staff experience, available resources and corporate culture. External factors were, however, the primary focus of respondents’ feedback, and included the reliability of energy supply in the target country, the condition of the built infrastructure such as roads and ports, tax rates and cost of finance, the prevalence of corruption as well as the risk of civil conflict and political instability. The Project Risk Guideline was the final output of this research process, which represented a synthesis between the literature review, the case study investigations as well as synthesis of various accepted risk evaluation techniques. The Guideline is a stage-gate sequential process, and may be utilised by civil engineering consulting or contracting firms with an interest in risk profiling and mitigation for project developments in emerging nations.

- Description: This research reviews the challenges and obstacles confronting multinational civil engineering consulting and contracting companies seeking to conduct project developments within Emerging Markets, specifically with regard to the regions of Africa and the Middle East. With the increasing convergence of the global economy towards an interconnected and co-dependant system, the emerging economies of previously underdeveloped parts of the world are now capturing the focus of the civil engineering industry as the primary area of operation. Multinational companies that historically were restricted to construction of the developed world must now adapt and reposition themselves with a footprint in these emerging markets, if they are to take advantage of the changing conditions within the global infrastructure construction industry. For companies historically unfamiliar with operating in Africa and the Middle East, a plethora of potential risks are associated with project development. This research incorporated a substantial literature study that determined a number of critical issues that directly and indirectly influence a company’s ability to complete a project within time and under budget. The literature bank was then tested against the expert opinions of four selected respondents utilising a case study research methodology, as detailed by Yin (1994: 1-17). The respondents represented two selected civil engineering consulting firms, one based in a developed country with an extensive interest in the Middle East, and the other based in an emerging country itself, with operations throughout Africa.
