- Description: Colorectal cancer (CRC) is a common disease with significant morbidity and mortality. In spite of significant advances in understanding the molecular signaling in this disorder, unanswered questions remain. Cyclooxygenase-2 (COX-2) and β-catenin have established roles in colorectal carcinogenesis, with both being upregulated early in the disease course. The role of peroxisome proliferator-activated receptor γ (PPARγ) is less clear, but has been shown to be downregulated in colon cancer models. Butyrate, a short chain fatty acid, produced by colon microbiota and transported into the colonocyte by transporter proteins, appears to be important in early carcinogenesis. The butyrate concentration is reduced in CRC and so are its transporters. Interleukin-17 (IL-17) plays a role in colitis-associated colorectal cancer (CAC), but its function in sporadic CRC is less clear. Similarly, Protein kinase C (PKC) has proven involvement in many solid tumours, including CRC, but its exact mechanistic role is still speculative. AIM: To investigate the role and possible signaling pathways of the major role players, β-catenin, COX-2 and PPARγ in early CRC. Further, to elucidate the mechanistic pathways of butyrate and its transporters, IL-17 and PKC in CRC. METHOD: Informed consent was obtained for all patients. Patients were recruited in various disease categories, including normal, irritable bowel syndrome (IBS), inflammatory bowel disease (IBD) and CRC. Colon biopsy specimens were obtained during colonoscopy and used for immunohistochemistry (IHC) and gene expression analysis of the above genes by quantitative polymerase chain reaction (qPCR). RESULTS: β-catenin mRNA and protein expression was increased in CRC and the IBD groups compared to the normal group, while it was reduced in the IBS groups. COX-2 mRNA expression showed a steady increase from normal, through IBS, IBD and CRC groups to a statistically significant degree. The COX-2 protein expression, however, did not match the mRNA expression with increased COX-2 protein expression in normal and IBS groups and reduced expression in IBD and CRC groups. PPARγ mRNA expression was unchanged in IBD and CRC groups, but significantly increased in the IBS group compared to normal. Butyrate transporter, SLC16A1 mRNA was significantly reduced in CRC, but also in the IBS groups, which was unexpected. In the IBD group, SLC16A1 mRNA was unchanged in Crohn’s disease (CD) but significantly reduced in ulcerative colitis (UC). Similarly, SLC5A8 mRNA expression was significantly reduced in the CRC as well as the IBS groups. In the IBD groups, SLC5A8 was unchanged in UC but significantly increased in CD. IL-17 mRNA expression was significantly reduced in CRC and IBS groups, but unchanged in the IBD groups. PKCε mRNA was significantly increased in CRC as expected. In the IBD groups, PKCε mRNA was unchanged in CD but significantly increased in UC. In the IBS groups, PKCε mRNA in constipation –IBS (C-IBS) was significantly reduced, but unchanged in diarrhoea – IBS (D-IBS). CONCLUSIONS: β-catenin mRNA and protein expression was increased in CRC and the CRC promoting IBD groups. COX-2 protein expression was incongruent with the COX-2 mRNA expression and this may reflect homeostatic control mechanisms. High COX-2 mRNA expression in CRC and CRC promoting IBD groups may be a secondary phenomenon reflecting the inflammatory milieu, rather than a true carcinogenesis-related event. PPARγ does not appear to play a central role in early colon carcinogenesis, in spite of available literature suggesting otherwise. Butyrate transporters showed inconsistent results and for now no firm conclusions can be drawn from this. IL-17 may play a role in CAC as confirmed in this and other studies, but its role in sporadic CRC is tenuous and requires further investigation. Likewise for PKCε, upregulation is associated with increased tumourigenecity as shown in this study, however, the mechanistic pathway(s) involved is still speculative and requires further study.

- Description: The human immunodeficiency virus/acquired immune-deficiency syndrome pandemic (HIV/AIDS) continues to increase in prevalence worldwide, particularly in South Africa. “AIDS, (Acquired Immune Deficiency Syndrome), has devastated the social and economic fabric of African societies, made orphans of a whole generation of children and become the epicentre of the HIV/AIDS pandemic” (Fassin, 2007: 76). Like the virus itself, the AIDS crisis mutates rapidly. Children who are AIDS orphans living in South Africa, as in other African countries, suffer from recurrent psychological trauma. It starts with the illness and death of their parents and is followed by cycles of poverty, malnutrition, stigma, exploitation, sickness and often sexual abuse. The figures concerning those affected, which are staggering, offer various predictions regarding the number of orphans left in the wake of the pandemic. Between 1990 and 2003, the number of orphaned children rose from fewer than 1 million to more than 12 million in sub-Saharan Africa (UNICEF, 2005: 68). South Africa is severely affected by the AIDS pandemic, with the largest number of HIV infections in the world, a total of 5.7 million (RSA, 2010: 10), affecting approximately 3.2 million women and 280 000 children aged from 0 to14 years. There is a significant variation in HIV prevalence per province, with the Eastern Cape (EC) reportedly having an average prevalence rate of 28 percent. Hence South Africa is likely to be the country with highest percentage of children orphaned by AIDS within its population. Orphanhood is a major consequence of the AIDS pandemic in South Africa with an estimated 2.2 million AIDS-orphaned children, 11,188 per 100,000 by 2015. Most children who are AIDS orphans living in township communities live predominantly uncared for and unsupported. Therefore the purpose of this research study was to develop strategies to provide care and support to children who are AIDS orphans living in township communities. To achieve the purpose of this research study, a qualitative, exploratory, descriptive and contextual design was used by the researcher to gain insight from health and social care practitioners who render care and support to children who are AIDS orphans living in these communities. The data from in-depth interviews with the health and social care practitoners was used by the researcher to develop strategies to provide care and support to children who are AIDS orphans living in township communities. The study comprised the following four phases: Phase One: During this phase, the researcher will present an overview of the current legislative framework policies at an international, national and provincial level, regarding the the rights of children living in South Africa. Phase Two: During this phase data from two research populations were collected and analysed. As the research process of this study dealt with two groups of participants, namely in group one health care practitioners and group two comprised social workers and psychologists, who work in the township communities to provide care and support to children who are AIDS orphans living in these communities. The researcher discussed each group separately in the discussion of phase two of the study. Phase Three: Comprised the themes identified in the data gathered from the transcribed in-depth interviews, the field notes as well as the reflective journals were cross-validated to ensure trustworthiness of the data which was then organised into a conceptual framework. The conceptual framework was used to clarify the relationships of the concepts and the themes identified during the research process and also used to link the gathered data to previously established models and theories (Schneider, 2004: 133). Phase Four: The last phase of the research design, focused on the development of the “Steps of progression strategies” to provide holistic care and support to children who are AIDS orphans living in township communities. This was done making use of the themes identified during data analysis and the literature sources used throughout this research process. The evaluation criteria of Chinn and Kramer (2008: 237-248) were used to evaluate the strategies. It is therefore concluded that the researcher succeeded in achieving the purpose of this study because strategies which were understandable, clear, simple, applicable and significant to nursing practice have been developed for use by the Department of Health and Department of Social Development as well as primary health and social care practitioners to provide holistic care and support to children who are AIDS orphans living in township communities in South Africa.

- Description: The wealth of information available on the Internet holds the potential to aid development in Africa. In order to be effective, such information needs to be contextualised to respond to local needs and practices. The combination of old and new media can support uptake and improve acceptance of new technologies in developing countries. The purpose of this qualitative study was to investigate the perceived usefulness of agricultural information sought on-line and broadcast via community radio in the two Community Multimedia Centres (CMCs) of Namaacha and Murrombene, in rural Mozambique. The data was generated from focus group discussion, individual interview, document analysis, and observation involving farmers and radio presenters. The study has shown that on-line agricultural information responds to the needs of the farmers because it contributes to eliminate pests and help farmers to make decisions about their activities. The study has also shown that there is a communication gap between farmers, extension workers, and volunteer reporters working at the community radios of the two CMCs. Volunteers have no agricultural knowledge. The problem this creates manifests itself primarily when they try to translate on-line agricultural information from Portuguese into local languages. Farmers have difficulties expressing their problems. Extension workers are not available to act as experts and mediators between volunteers and farmers. A collaborative website focusing on locally relevant content was suggested as a possible improvement.

- Description: False codling moth, Thaumatotibia leucotreta(Meyrick, 1913) (Lepidoptera: Tortricidae), is animportant pest on citrus in South Africa. Several new insecticides were screened for theirpotential negative impacts onT. leucotreta’s reproduction through topical insecticide applica-tions and detached fruit bioassays. Detached fruit bioassays showed that the registeredstandard concentration of Delegate®20 g/100 l and DPX-HGW86 35 ml/100 l caused femalesto oviposit significantly fewer eggs (P= 0.0016) than the controls. The same was found forthe registered concentration of Coragen® (P is less than 0.0001). Topical insecticide trials showed thatonly concentrations of Coragen®, at the registered field rate and above had an effect on themoths’ reproductive output (P is less than 0.0001). Alsystin®and Meothrin™, which were used asindustry standards, did not negatively affect the reproductive output of the moths duringtopical or detached fruit bioassay trials. This study helps to better understand the impor-tance of the application mode,i.e.directly on moths or fruit and implies secondary benefits tosome insecticide applications.

- Description: It is typically said that there are two questions that political philosophy seeks to address: ‘who gets what?’ and ‘who decides on who gets what?’ South Africa, along with much of the rest of the world, has answered the second question badly and currently ranks as one of the world’s most unequal societies. Counter-intuitively, South Africa maintains a social-political order that (re)produces this inequality along with great enthusiasm for ubuntu, an African ethic that at a minimum requires that we treat each other humanely. However, due to the view that ubuntu has been co-opted in support of South Africa’s unjust system, ubuntu has largely been ignored by radical thinkers. The aim of this thesis is therefore to explore the possibility of an ubuntu-based political philosophy, with the core assumption that political philosophy is rooted in ethical theory. Three tasks are therefore undertaken in this thesis. Firstly, ubuntu is articulated as an ethic. Secondly, it is compared to similar Western ethical theories in order to determine if there are distinguishing characteristics that make ubuntu a more appropriate founding ethic for South African political philosophy. Finally, whether ubuntu can find real-world applicability will be assessed by looking at the way ubuntu has been used in the law

- Description: For more than a decade (2001 – 2012) there has been extensive research conducted on the impact of marketing on food consumption, the promotion of healthy lifestyles and the use of media communication channels in the restaurant industry. However, no known research has focused specifically on the healthy fast-casual restaurant segment with a specific focus on media communication channels. This study attempts to address this limitation. The study deals with selected media communication channels and their influence on the healthy lifestyle perceptions and healthy lifestyle purchase intentions of young adult consumers in South Africa. The study considers the impact that a more selective choice of media communication channel can have on restaurants in the healthy fast-casual restaurant segment. Media communication channels are a vital part of a restaurant’s marketing communication program as they transmit messages between the business and its target market. In South Africa’s restaurant industry, there are numerous businesses that are conveying messages to consumers regarding their market offerings. This advertising clutter is aggravated by healthy fast-casual restaurants needing to compete against traditional fast-casual restaurants who are adding healthier items to their menus. The study’s secondary research included a literature review on marketing communication, selected media communication channels (print media, display media, broadcast media and online media) and the South African restaurant industry (with a focus on the healthy fast-casual segment). In addition, perception and purchase intention were discussed with a focus on healthy lifestyles and young adult consumers. In order to establish the influence of the selected media communication channels (print media, display media, broadcast media and online media) on young adults’ healthy lifestyle perceptions and healthy lifestyle purchase intentions an empirical investigation was also conducted. A positivistic research paradigm was used as quantitative methods were performed to identify significant relationships among the selected variables. The sample consisted of students from the Nelson Mandela Metropolitan University. A total of 440 questionnaires were distributed, with 350 usable. Therefore, a response rate of 79.55 per cent was obtained. The empirical investigation revealed that the items in the questionnaire that were used to gather information about healthy lifestyle perception and healthy lifestyle purchase intention loaded together on one factor which was renamed healthy lifestyle buying behaviour. Multiple regression analysis indicated that positive and statistically significant relationships existed between print media and healthy lifestyle buying behaviour and between online media and the healthy lifestyle buying behaviour of young adults. These relationships imply that an increased use of print media will reflect increased buying behaviour that supports healthy lifestyles amongst young adults. Similarly, the more online media is used, the more young adult buying behaviour will reflect healthier choices. This implies that restaurants in the healthy fast-casual restaurant segment can increase the demand for their market offerings and stand out amongst the advertising clutter through a more deliberate use of print media and online media. The study includes strategies that can be used to improve the use of print media and online media in order to influence the healthy lifestyle buying behaviour of young adults. Healthy lifestyle buying behaviours essentially will increase the demand for goods that support healthy lifestyles and therefore increase the demand for healthy fast-casual restaurants. The provision of healthy menu items and a more focused marketing program can be used as a strategy to attract more young adults as consumers, to grow business relationships with this target market, to enhance business performance and to create a healthier South African community.

Similarly, the more online media is used, the more young adult buying behaviour will reflect healthier choices. This implies that restaurants in the healthy fast-casual restaurant segment can increase the demand for their market offerings and stand out amongst the advertising clutter through a more deliberate use of print media and online media. The study includes strategies that can be used to improve the use of print media and online media in order to influence the healthy lifestyle buying behaviour of young adults. Healthy lifestyle buying behaviours essentially will increase the demand for goods that support healthy lifestyles and therefore increase the demand for healthy fast-casual restaurants. The provision of healthy menu items and a more focused marketing program can be used as a strategy to attract more young adults as consumers, to grow business relationships with this target market, to enhance business performance and to create a healthier South African community.

- Description: The demand for faster data transmission is ever increasing. Wavelength division multiplexing (WDM) presents as a viable solution to increase the data transmission rate significantly. WDM systems are based on the ability to transmit multiple wavelengths simultaneously down the fibre. Unlike time division multiplexing (TDM) systems, WDM systems do not increase the data transfer by increasing the transmission rate of a single channel. In WDM systems the data rate per channel remains the same, only multiple channels carry data across the link. Dense wavelength division multiplexing (DWDM) promises even more wavelengths packed together in the same fibre. This multiplication of channels increases the bandwidth capacity rapidly. Networks are looking into making use of technology that will ensure no electronic signal regeneration at any point within the DWDM network. Examples are; reconfigurable optical add/drop multiplexers (ROADM) and optical cross connect (OXC) units. These components essentially enable network operators to split, combine and multiplex optical signals carried by optical fibre. WDM allows network operators to increase the capacity of existing networks without expensive re-cabling. This provides networks with the flexibility to be upgraded to larger bandwidths and for reconfiguration of network services. Further, WDM technology opens up an opportunity of marketing flexibility to network operators, where operators not only have the option to rent out cables and fibres but wavelengths as well. Cross phase modulation (XPM) poses a problem to WDM networks. The refractive index experienced by a neighbouring optical signal, not only depends on the signal’s intensity but on the intensity of the co-propagating signal as well. This effect leads to a phase change and is known as XPM. This work investigates the characteristics of XPM. It is shown that, in a two channel WDM network, a probe signal’s SOP can be steered by controlling a high intensity pump signal’s SOP. This effect could be applied to make a wavelength converter. Experimental results show that the degree of polarization (DOP) of a probe signal degrades according to a mathematical model found in literature. The pump and probe signals are shown to experience maximum interaction, for orthogonal probe-pump SOP vector orientations. This may be problematic to polarization mode dispersion compensators. Additionally, experimental results point out that the SOP of a probe signal is much more active in the presence of a high intensity pump, as compared to the single signal transmission scenario.

- Description: Municipalities play an important role in accelerating service delivery to all communities. This study is an assessment of skills development programmes for selected employees at the Amathole District Municipality (ADM). The ADM is known as a predominantly rural district. The study revealed that the municipality is faced with a lack of proper skills to accelerate service delivery. This has resulted in the institution neglecting to invest in the development of those competencies needed to function in a constantly changing educational, training and development environment. The success of any organisation depends on its human resources, who are the most important asset. Therefore effective and efficient human resources management and training and development management play a critical role in the well-being of employees. Human resources training and development policies, practices and activities guide the institution with implementation of services and should take on a more strategic role to achieve their objectives. The researcher employed the quantitative research methodology for purposes of the empirical survey and also reviewed official documents and reports. A suitably constructed questionnaire was developed and distributed to the selected sample group from the ADM. The researcher also consulted legislation, official documents, articles, journals, policy documents, reports and books in an effort to obtain as much relevant information as possible. Based on the information gathered from the respondents and literature review the researcher proposes certain recommendations in the final chapter of the treatise.

- Description: Increasing competition within the non-alcoholic, ready to drink market (NARTD) in South Africa has intensified the need for soft drink producers to identify ways in which to enhance their competitiveness. One of the most important challenges for organisations operating in this industry is to produce quality products while meeting the needs of customers, at the lowest possible cost. While a number of competitors may rely on various competitive strategies such as lower priced products, it could become increasingly challenging for others to adopt similar approaches without comprising on the quality of their products. In order to remain competitive, organisations may be required to shift their focus onto their employees as a source of competitive advantage. Research has shown that employees provide organisations with sustainable competitive advantage, more specifically, it has shown that engaged employees outperform disengaged employees. The differentiating factor for organisations in the pursuit of competitive advantage would therefore be an engaged workforce. The primary research objective of this study was to investigate employees’ perceptions of engagement within the logistics function at Coca-Cola Fortune Port Elizabeth, as well as its impact on critical success factors. A theoretical overview was conducted to appraise various definitions, engagement models, factors influencing engagement and the impact of engagement on critical success factors. The research highlighted a number of common themes of engagement which includes a reciprocal relationship between the organisation and employees, enthusiasm, involvement and motivation. This research revealed that engaged employees make positive contributions to key business outcomes such as financial performance, productivity and customer satisfaction.An empirical study was conducted by means of a survey with a questionnaire as data collecting tool. The purpose of the structured questionnaire was to validate the findings obtained from the theoretical overview and to assess employees’ perceptions of engagement, engagement factors and the impact of engagement on critical success factors. A sample comprising 112 employees was identified by means of a stratified sampling technique. A 93 per cent response rate was obtained. The key findings of the study indicated that management and employee perceptions of engagement were comparable. It also indicated that corporate communication, employee involvement strategies, relationships with management and HR policies and procedures did influence employee engagement. Furthermore, the study validated the existence of a strong positive relationship between customer satisfaction, employee attendance and productivity – as was found between employee engagement and business success at CCF. The theoretical overview in conjunction with the empirical findings yielded a hypothesised model of employee engagement as presented in Chapter One. This model could provide direction in the organisation’s attempt to improve engagement levels and ultimately in the pursuit of competitive advantage.

- Description: In 1996, Zimbabwean graphic designer Chaz Maviyane-Davies created a set of human rights posters which represent several articles of the Universal Declaration of Human Rights, from what he calls an “African perspective”. In this study I investigate how Maviyane-Davies has constructed ‘African-ness’ and probe what he refers to as the “alternative aesthetic” that he is trying to create. I use a visual social semiotic approach to examine the discourses he draws on to re-image and re-imagine Africa and Africans in a manner that contests the stereotypical representations found in political, news and economic discourses about Africa, paying particular attention to the ways he uses images of the body. My analysis of the posters shows how complex and difficult it can be to contest regimes of representation that work to fix racialised and derogatory meanings. In response to the pejorative stereotypes of the black body, Maviyane-Davies uses images of strong, healthy, and magnificent people (mostly men) to construct a more affirmative representation of Africa and Africans. Significantly, he draws on sports, touristic, traditional and hegemonic discourses of masculinity in an attempt to expand the complexity and range of possible representations of African-ness. In so doing he runs the risk of reproducing many of the stereotypes that sustain not only the racialised and gendered (masculinist) representations of Africa, but also a sentimentalisation and romanticisation of a place, a people and their traditions. Apart from women in prominent positions, other conspicuous absences from these images include white people and hegemonic references to Western modernity. I do not believe he is discarding whites and modernity as un-African, but is rejecting the naturalisation of whiteness as standing in for humanity, and particular icons of Western modernity as significations of ‘modernity’ itself

Characterisation and biotic classification of Eastern Cape mixed substrate shores

- Description: A significant proportion of the South African coastline is composed of both soft (mostly sand) and hard (mostly bedrock) substrata, i.e. “mixed”. This study described and classified macrobenthic assemblages of 20 Eastern Cape mixed substrate shores that differed in shore topography and the extent and position of intertidal rock and sand. A stratified random approach was used. Species richness, composition, abundance and environmental variables were determined. Commonly used beach indices were calculated. A total of 78 macrofaunal and 172 macroalgal species from rock substrate assemblages and 205 macrofauna species from sediment were recorded. Total species richness and richness per substratum exceeded that of sandy beaches devoid of rock and rocky shores with no sand. Rhodophyta were the most diverse and abundant algae, dominating all low-elevation rock surfaces as midlittoral and infralittoral turfs. Chlorophyta diversity was higher than at rocky shores, contributing more to cover-abundance at study sites and in microhabitats with an increased sand load. Sessile macrofauna species richness and abundance was lower than that of rocky shores. Polychaetes and crustaceans were the most diverse and abundant beach infauna. Species richness of both substrates declined from the low shore towards the high shore, but abundance trends varied substantially. The presence and extent of an intertidal biotope/subzone at either substrate depended on substrate availability.The supralittoral fringe in both substrate types was most often affected. Zonal overlap was evident on rock substrate: assemblages of raised midlittoral rock surfaces were enriched by species from lower surfaces sometimes leading to elimination of character taxa. Classification and ordination identified three potential mixed substrate shore biotic types: Biotic type A (Jania-Corallina- Polysiphonia turf) was characterised by robustly-textured algal turfs, a lowered predominance and diversity of polychaetes and an increase in crustacean abundance and diversity in sediment. Biotic type B (Polysiphonia-Tayloriella-Caulacanthus turf) had intermediately and biotic type C (Arthrocardia-Laurencia turf) the most sheltered eulittoral zones and beaches. DCCA identified the major environmental parameters affecting the macrobiota as: the level of wave energy, geological control of waves by hard substrate, sediment grain size and sediment inundation. A strong cross-shore wave attenuation results in sheltered sediments and midshore rock surfaces. Beach macrofauna were highly variable and diverse, which directly opposes previous perceptions about the sediment-bound biota of mixed substrate shores. The hierarchical cluster analysis produced a biotic classification of mixed substrate shores that was indicative of a biotic response to the total effects of leading environmental parameters. Macrobenthos of rock surfaces and sediment therefore showed potential to be used as an alternative or complementary to physical characteristics in classifying mixed substrate shores.

Species richness of both substrates declined from the low shore towards the high shore, but abundance trends varied substantially. The presence and extent of an intertidal biotope/subzone at either substrate depended on substrate availability.The supralittoral fringe in both substrate types was most often affected. Zonal overlap was evident on rock substrate: assemblages of raised midlittoral rock surfaces were enriched by species from lower surfaces sometimes leading to elimination of character taxa. Classification and ordination identified three potential mixed substrate shore biotic types: Biotic type A (Jania-Corallina- Polysiphonia turf) was characterised by robustly-textured algal turfs, a lowered predominance and diversity of polychaetes and an increase in crustacean abundance and diversity in sediment. Biotic type B (Polysiphonia-Tayloriella-Caulacanthus turf) had intermediately and biotic type C (Arthrocardia-Laurencia turf) the most sheltered eulittoral zones and beaches. DCCA identified the major environmental parameters affecting the macrobiota as: the level of wave energy, geological control of waves by hard substrate, sediment grain size and sediment inundation. A strong cross-shore wave attenuation results in sheltered sediments and midshore rock surfaces. Beach macrofauna were highly variable and diverse, which directly opposes previous perceptions about the sediment-bound biota of mixed substrate shores. The hierarchical cluster analysis produced a biotic classification of mixed substrate shores that was indicative of a biotic response to the total effects of leading environmental parameters. Macrobenthos of rock surfaces and sediment therefore showed potential to be used as an alternative or complementary to physical characteristics in classifying mixed substrate shores.

- Description: The aim of the study was to explore the effects of the absence of an overarching national information policy on information services in Malawi. The objectives of the study were to: find out the effects of the absence of an overarching national information policy on information access in Malawi; establish factors impeding the development of an overarching national information policy in Malawi; find out the extent to which the absence of an overarching policy has affected capacity building in information services in Malawi; and identify the legal and regulatory framework implications of the absence of such a policy in Malawi. The study adopted an exploratory research design. Data were collected using document analysis, observations and in-depth interviews. Eighty-two face-to-face interviews were conducted with policy makers in government, Members of Parliamentary committees on legal and media issues, information scientists, information service providers, academicians, legal experts and information users. Purposive sampling was used to select participants. An interview guide comprising closed and open ended questions was used to interview respondents. Data were analysed using quantitative and qualitative methods. The findings of this study may be used by Government in developing relevant national information policies that would enhance free access and utilisation of information. Furthermore the study is significant in identifying factors that may impede the development of a national information policy. The study revealed that Malawi has a brittle national information policy framework for the provision of information services. Malawi doesn’t have an overarching policy framework for the sector and as a result, there is no policy guidance to drive the development of sectoral policies and supporting legislation. Policy development in Malawi is more reactive to issues than systematic and very slow. Consequently, access to and utilization of information is low; capacity building is low in terms of competencies and infrastructure and; the legal and regulatory framework for information services is weak. The study also revealed that factors impeding the development of an overarching national information policy include: motivation for the development of sectoral information policies; lack of an institutional framework to guide the development of policy; lack of finances and technical capacity; lack of sustained political will; level of economic development; existence of overarching government development plans; international trends; and the diverse nature of the information sector. The general recommendation emanating from the findings of the study is that Malawi needs an overarching national information policy which would articulate and address issues regarding access to information, capacity building in terms of skills and infrastructure, and the legal and regulatory framework. Information is a cross-cutting issue requiring an all-encompassing policy. However, specific recommendations from the findings of this study are that government should expedite the development of policies and enactment of relevant pieces of legislation which are not yet in place to enhance free access and utilisation of information and ICTs; government should speed up the introduction of information literacy in the school curriculum starting from primary school level to university; government should develop a library policy to promote the development of school libraries in both primary and secondary schools, and public libraries in all towns, district assemblies and rural growth centres which should be well resourced including Internet facilities; and government should constantly review and harmonise policies and legislation in the information sector so that they are in line with current trends.

- Description: The majority of South African public schools are not performing well considering the overall learner success rates in specifically so called disadvantaged schools. Many factors contribute to this situation, however, all education stakeholders contribute in some way to the success or failure of schools. In this regard alumni of disadvantaged schools in South Africa have not played an active role in supporting their alma maters. This research sought to identify the various roles alumni can play in the development of disadvantaged schools. As innovative strategies to the public education crisis in South Africa are required, one such strategy is to involve a neglected stakeholder group such as alumni to share their skills and resources towards improving the different aspects of school development. There are very few examples of functioning alumni associations at previously disadvantaged schools in the Eastern Cape. Sharing information on a study of two selected schools with already established alumni associations could be of value to other schools in the establishment of their own alumni associations in order to support school improvement and development initiatives. Therefore, based on the findings of this study and from evidence in literature, the researcher concludes that alumni associations can play a meaningful role in developing and transforming disadvantaged schools in a young and developing democracy as in the case of South Africa. This study looked at, amongst other aspects, at the roles and contributions that alumni may play in the development of their alma maters and finally offer guidelines in the establishment of alumni associations.

- Description: When the Arab Spring took place, it took the world by surprise and sparked renewed interest in the idea of revolution. With differing opinions on what caused such a revolutionary wave throughout the North African and Middle Eastern region, many began looking at their own countries, and South Africa was no different. A debate was sparked in South Africa, as to whether there would be a revolution or not. What I originally set out to accomplish is to find out which side of the debate would be correct through the philosophical context of revolutionary theory. Initially, we attempted to define and consider the history of revolutionary theory. We found that revolutionary theory has gone through four generation and that even finding a theoretically informed definition is difficult. Following this, we considered some social-psychological theories of revolution as well as theories of moral indignation. We found that these theories were incredibly informative and that they provide some insight into the reasoning for revolutionary fear in the South African debate. Through the use of opinion pieces, we then considered the South African debate, and – using socialpsychological theories and the theories of moral indignation - found that both sides of the argument had valuable points, however, they often lacked some foresight. With tentative agreement, we found that the side arguing that there would a revolution in South Africa had a more valuable argument, despite its limitations. However, far more research is required before one can – with more accuracy – predict a revolutionary occurrence in such a way as was done in South Africa.

- Description: It is critical in this dynamic and changing environment that both the leadership and educators of schools and organisations are well equipped with the skills and knowledge to create high performance teams (HPT). High performance teams can be defined as those highly motivated team players in the organisation or school that maximise their people integrated knowledge, skills and values to a shared purpose or vision of their stakeholders. In this mixed method research an analysis of the whole school operational teams of some secondary schools including all educators, head of departments, administrators and principals was undertaken. Four secondary schools from two quintile groups situated in various areas of the Nelson Mandela Bay Metropolitan were the sampling units and the sample size was eighty one. Both quantitative and qualitative data was collected utilising a carefully constructed questionnaire based on a theoretical conceptual framework of enabling factors for HPT in business contexts. The theoretical framework of the Kenexa High Performance Model was utilised in this study. A questionnaire was constructed based on the factors of the High Performance Work Index (HPW) study done by the Australian Business School. This model was adjusted to utilise factors aligned to those factors within the school operational context. Using other literature references further factors were included into the survey instrument. The School High Performance Work Index (SHPWI) was the dependent variable while the independent variables included organizational commitment, and employee engagement. These were literature based measures and the questionnaire items were taken from previous research studies, thereby allowing construct validity. The other independent variables included Communication, Leadership, Strategic Management, School Organizational Climate, Positive Practices, Conflict Management, Motivation and Trust. A statistical analysis was undertaken on each school’s team response data. Reliability and validity of the constructed questionnaire was shown by using the Kenexa employee engagement index and the Organizational Commitment measure, which were highly correlated with the SHPWI. In literature, high performance teams (HPT) show common patterns in business and in this study it was seen that a number of common factors contributed towards a HPT in school operational teams. In this research study the main enabling factors in whole school operational teams that could lead to the formation of HPT’s involved factors of leadership, communication and motivation. The SHPWI showed a high correlation with employee engagement and organizational commitment. The HPT profile involved innovation (freedom of thinking), employee (educator) engagement, fairness, leadership, learner needs, communication, trust, conflict management, school organizational climate, positive practices, strategic management and motivation. In the correlation between the SHPWI and the independent variables the highest correlation (statistically significant at p < 0.05 N = 81; r > 0. 500) occurred between the School High Performance Index and Leadership (0.822), Communication (0.785) and Motivation (0.766). In the multiple linear regression (MLR) of the results of this study the highest correlations with a value of R2 = 0.774 was obtained with variables of Leadership, Communication, Motivation and Strategic Management factors. Qualitative data was coded and linked with the factors in the quantitative data and the top five factors were selected and summarised for each school. Merged data showed that each school exhibited a different profile of strengths and weaknesses. Recommendations were outlined for each school operational team. Different schools in different quintiles have different needs and gap factors that require improvement. It is therefore imperative that schools analyse their strengths and weaknesses within their school operational teams. This research study aimed therefore to start research on a human resource metric that can be further developed to allow school operational teams to examine and analyze their own HPT profile, so that specific interventions may be implemented.

- Description: Adventure tourism (AT), defined as “a broad spectrum of outdoor touristic activities,often commercialized and involving an interaction with the natural environment away from the participants’ home range and containing elements of risk,” (Hall, 1992, p. 143) is currently one of the fastest growing sub-sectors of the tourism industry (Buckley 2010). Because it has emerged relatively recently as a field of study, a number of scholars have called for ongoing research in the area, see Swarbrooke (2003), Pomfret (2006), Buckley (2010), Rogerson (2007), and Williams & Soutar (2005). Much of this research, to date, has focused on marketing, injury caused by AT participation, environmental impacts, and the broad notion of “risk” associated with AT. The problem is that little of this work has focused on the significance of the environment in adventure tourism – an important element inherent in its definition. Thus, this thesis aims to move beyond a general risk-based analysis of AT, and focus on the role of the environment. This is done through a human-environment interaction approach undertaken in Tsitsikamma Village where five adventure tourist operations are based. The first step in operationalizing this approach was to develop a conceptual framework that integrated adventure tourism into a general framework on humanenvironment interaction. The second step was to use a research instrument which enabled one to examine the influence of the environment on human motivations and adventure tourism experiences, and not only the influence of humans on the environment. The former was accomplished through questionnaires based on external, environmental elements that attract adventure tourists as well as inherent personality traits impel such tourists to participate in AT. The latter, based on interviews and participant perceptions, sought to establish the significance of impacts on the environment as well as initiatives taken by AT companies to minimize environmental damage. The findings show that although risk/thrill does play a role, AT motivations and experiences are complex and multidimensional. The environment does significantly influence both motivations and even more so AT experiences. Furthermore, there are distinct differences between the motivations and experiences of participants in different types of AT activities, indicating that generalizing the industry as whole neglects these significant differences. In terms of influences on the environment, the results show that most AT operators in the Tsitsikamma have some consideration for environmental protection and take some initiatives to minimize environmental damage, though the degree to which this occurs differs significantly. Furthermore, activity participants do not believe that the activities have a strong negative impact on the environment, though the majority acknowledge small impacts. The types of impacts observed by participants vary significantly between companies. This thesis demonstrates the manner in which the two-way relationship between humans and the environment manifests itself in the commercial AT industry. The result is a well-rounded examination of the influence of human-environment interaction on AT participants.
