- Description: This study locates the Blackboard Learning Management System as a Technology Enhanced Learning tool within the bounds of the discipline of eLearning and aimed to interrogate the use of Blackboard for the purposes of teaching, learning and assessment in large classes. It is evident from the literature reviewed that changes in both Higher Education in the South Africa with regards to policy and legislation in addition to international shifts towards increased access and participation in a fast paced, ever-evolving knowledge-based economy, providing the context for this work. The theoretical framework for this study is not unidimensional due to the fact that the educational field of eLearning as an area of specialisation draws on a multitude of theories in terms of their utility value for instructional design of courses utilising Information and Communications Technology as a mode of delivery. This study was conducted within the bounds of an interpretivist paradigm as the researcher sought to focus on the use of Blackboard and the experiences of the lecturers and students involved in the implementation thereof. The research design for this study took the form of a case study and a multiple case method was employed. The researcher collected data through personal interviews conducted with participating lecturers, while student data was collected by means of a qualitative survey which was conducted through the Blackboard Learning Management System. The data was analyzed by means of a thematic analysis, consistent with the interpretive paradigm chosen for this study. The findings of this study revealed that Blackboard was utilised effectively in order to facilitate communication, access to course resources and promoted more efficient assessment processes. The implementation was however not without challenges many of which were systemic and focused on the lack of resources available to the students. The implications of using Blackboard for teaching and assessment of large classes include the use of the Learning Management System as part of a multimodal method of course delivery in an effort to reach the multitude of registered students both conceptually as well as electronically. The recommendations arising from this study include consideration on the part of the faculty for a unified approach in the use of Blackboard for communication as well as deployment of resources. Additionally, this study may form the foundation of further studies in this field, with a focus on the active engagement and training of lecturers in order to integrate traditional teaching methods with blended learning opportunities.

- Description: The present study investigates the use of English and isiXhosa in teaching and learning Physical Sciences in four King Williams Town schools. Physical Sciences educators and Grade 11 Physical Sciences learners were interviewed to find out about their perceptions with regard to the language(s) used in the learning and teaching of the subject Physical Sciences. The same educators and learners were also observed to find out their actual language practices in class. The findings revealed that English was the preferred medium of instruction in the learning and teaching of Physical Sciences, even though the majority of learners had low proficiency in English. Both teachers and learners extensively use code-switching to bridge this language gap in order to improve the learning of content. The choice to use isiXhosa to bridge the English second language barrier was influenced by the language profile of the learners. However, even in lessons in which teachers used code-switching, the participation of learners in class discussions was very low because the delivery of the lessons was still teacher-centred. The National Department of Education assessment policy seems to limit schools toward adopting English as the LoLT even though learners in these schools were isiXhosa first language speakers. The fact that all assessment are done in English leads to school adopting English on LoLT. Schools adopted the English only policy as way of promoting learners’ learning and understanding of English, so that the learners are not disadvantaged by the English language factor when writing examinations.

- Description: The purpose of this study was to provide professionals practising sports public relations in South Africa with insight into the use of social media platforms Facebook and Twitter. The secondary data from this study was drawn from the fields of communications, public relations, new media, social media, sport and marketing. South African Paralympic swimmers Kevin Paul and Shireen Sapiro were selected as the case studies and their Facebook and Twitter sites were analysed. The data was analysed leading up to, during and after the 2012 London Olympics and Paralympics. Content analysis using quantitative and qualitative data was utilized to conduct this study. During the period 27 July to 30 September 2012, the study was able to evaluate data by identifying the reach, frequency, interaction of the stakeholders and the positive or negative impact social media had on these athletes. The study established that there were correlations between the secondary and primary research that was undertaken. The findings revealed that social media platforms Facebook and Twitter can be useful tools to communicate with stakeholders. Social media can also create support for the athletes, create two-way interaction, create unity and enhance reputation. It was identified that social media could only be effective if it enticed stakeholders to engage with the brand and create two-way communication. Immediate feedback by responding to comments as soon as possible to build and maintain relationships with stakeholders is essential. This can be done through comprehensive planning, monitoring and proactively seeking ways to satisfy stakeholder needs.

- Description: A question asked at the United States of America (USA) National Council for Geographic Education (NCGE) conference in 1967, namely, what learning does GIS allow that other ways do not and whether teaching GIS at school level is worth the time and effort required to implement it, remains largely unanswered. Literature searches suggest that little more has been done since 1967 to investigate the effectiveness of GIS in education, or that there are any findings to suggest that GIS is worth the time and effort to implement in schools. Internationally the implementation of GIS software and geo-spatial data in schools has been slow, and South Africa is no exception. The main reasons given for slow implementation internationally have included lack of resources, lack of training and lack of time. The majority of secondary schools that offer Geography in the Port Elizabeth Education District, South Africa, teach GIS theory without the use of GIS software and geo-spatial data. The purpose of this research was to elicit the perceptions of secondary school level Geography teachers and learners of the benefits, barriers and obstacles to implementing GIS software and geo-spatial data as a teaching strategy. As a focused exercise to investigate what learning using GIS allows that other ways do not, this study also investigated whether using GIS as a teaching and learning strategy enables the promotion of learners spatial cognition, spatial perspective taking and problem solving abilities better than traditional methods do. The findings are viewed through the lens of developing Crystallized Intelligence (Gc), Spatial Intelligence (Gv) and Fluid Intelligence (Gf), respectively. The study followed a concurrent transformative mixed methods design with pre-post testing and the use of crossover experimental and control groups to generate both qualitative and quantitative data. Questionnaires aimed at all secondary Geography teachers in the Port Elizabeth Education District were used to assess how GIS is taught in their schools and to evaluate their perceptions of the benefits and barriers of implementing GIS software and geo-spatial data in the classroom. Four secondary school Geography teachers in four schools volunteered to take part in the experimental aspects of the study. Empirical data on the development of spatial cognition, spatial perspective taking, and problem solving were generated via pre- and post-tests in which the grade 11 Geography learners participated. Experimental and comparison groups of learners wrote four different types of pre- and post-tests where the experimental groups worked on GIS software with geo-spatial data while the comparison groups used traditional methods. Teacher interviews and learner interviews were also conducted to assess attitudes towards GIS software and geo-spatial data as a teaching strategy. The results from this aspect of the study mirrored the benefits and barriers to implementing GIS in schools recorded in international literature. However, and possibly more importantly, the empirical data generated by the learners revealed that GIS software and geo-spatial data do statistically significantly promote better spatial cognition (Crystallized Intelligence) and spatial perspective taking (Spatial Intelligence) than traditional methods do (i.e. using atlases, rulers and calculators). No improvement was found in the experimental groups‟ problem solving abilities. This report offers possible explanations and recommendations in terms of socio-cultural findings from other educational studies on the effects of exploratory talk on the development of Fluid Intelligence. Recommendations are made for the attention of curriculum developers, teachers, school principals, departmental officials and other educational stakeholders in terms of what is required for the successful implementation of GIS software and the use of geo-spatial data in secondary school Geography classes.

- Description: In 1997 industrialized nations, the Third Conference of the Parties to the United Nations Framework Convention on Climate Change, met in Kyoto, Japan to sign a treaty (the “Kyoto Protocol”) in terms of which industrialized nations would be required to reduce their greenhouse gas emission by at least five percent below 1990 levels by the end of the “first commitment period” 2008-2012. South Africa is not regarded as an industrialized nation, but nonetheless acceded to the Kyoto Protocol in 2002. The literature reviewed in the present research reveals that, although idealistic, the Kyoto Protocol has been problematic. Fourteen meetings of the Conference of Parties to the Kyoto Protocol between 1997 and 2011 have achieved little more than to repeatedly defer and redefine Kyoto obligations. This research was undertaken to document the existing environmental taxation policies employed in selected international jurisdictions with a view to providing a framework for environmental tax policy formation in South Africa to assist this country in meeting its “greenhouse gas” emission targets, while at the same time promoting economic growth. A doctrinal research methodology was adopted in this study as it mainly analysed and interpreted legislation and policy documents and therefore the approach was qualitative in nature. An extensive literature survey was performed to document the various environmental policies that have been legislated in the selected jurisdictions. Comparisons were drawn with proposed tax policy measures for South Africa. The literature indicates that in the selected international jurisdictions carbon taxes achieved less-than-optimal results, largely due to political and industry-competitive agendas. With South Africa planning to introduce a carbon tax, it is submitted that the implementation of a carbon tax regime in isolation will be counter-productive, given South Africa’s economic profile. On the basis of the literature reviewed, it was concluded that South Africa should consider “recycling” carbon tax revenues within the economy to fund a broad-based tax incentive regime that will stimulate the change to non-carbon energy whilst promoting growth through sustainable development

- Description: Experience has shown that effective fisheries governance requires a sound understanding of fisheries as systems incorporating both ecological and human dimensions. The Ecosystem Approach to Fisheries requires that the human components of these systems be considered when developing management and governance frameworks. While the potential for inland fisheries to contribute towards societal welfare and the development of rural livelihoods is becoming increasingly apparent, developing South African inland fisheries requires a careful consideration of both their positive and negative impacts, given that they revolve mainly around five of the world‟s top 100 invasive species. This thesis aimed to explore the value of inland recreational fisheries to rural livelihoods in the Amathole District of South Africa, to the regional economy, and to anglers themselves. Three methods were used to isolate this value. Economic impact analysis was used to estimate the combined total economic impact of the 2011 Divisional Tournament (n=31) and the 2012 Amatola Bass Classic (n=100) on the regional economy of the Amathole District, estimated to be R106 625. The travel cost method was applied to data from the 2012 Amatola Bass Classic in order to estimate the social welfare generated by this tournament. The Negative Binomial model, corrected for truncation and endogenous stratification, estimated this value at R 1 960 090. The sustainable livelihoods framework was used to conduct a broad-based analysis of the value of Amatola Wild Trout, the firm which constitutes the fishery surrounding the rural village of Cata. It was found that the fishery had been responsible for a modest pecuniary impact on the community of Cata within its first two years of establishment, although significant improvements in human capital were found to have resulted from the development of the fishery. These results provide insights into the economic dimension of fisheries in the Amathole District, and will prove useful when weighing up the positive and negative impacts of non-native fish species, particularly when informing decisions regarding their potential eradication.

- Description: Radio Frequency Identification (RFID) is revolutionizing business practices across industries worldwide as means for its commercial application continue to be developed. It is surpassing barcoding as the preferred means of product identification due to its’ ability to identify goods at item-level as opposed to batch- or type identification, and with no line-of-sight requirements for item detection. Although many industries have successfully employed the technology and are reaping the rewards, RFID’s adoption in the truck tyre industry is still in its infant stage. A small number of documented cases discuss the limited roll-out and testing of RFID effectiveness in satisfying the demands and expectations associated with this specific application. This study is aimed at evaluating the viability of introducing RFID to the South African market. The market readiness is reflected in the perceptions of Continental Tyre South Africa’s (CTSA’s) customers regarding the perceived benefits of RFID. More importantly, it is revealed in how it affects customers’ buying behaviour and, by implication, the impact on CTSA’s sales. The results of the study also reveal critical aspects unique to the South African truck tyre market which could potentially be addressed through the introduction of RFID. These aspects form the basis of the conclusions and recommendations for future actions by CTSA.

- Description: This thesis unites law and social science so as to give a comprehensive account of the phenomenon of racial hate speech in South Africa as an obstacle to transformation. Hate speech is presented as a form of violent language and an affront to the constitutional rights of freedom of speech, equality and dignity. To establish the nature of hate speech, the fluid quality of language is explored so as to show how language can be manipulated, on the one hand, as a means to harm, and employed, on the other hand, as a tool to heal and reconcile. This double gesture is illustrated through the South African linguistic experience of past hate and segregation and the current transformation agenda. It is through this prism that hate speech regulation is discussed as an uneasy fit in a country where freedom of expression is constitutionally protected and where language plays an important role in bringing about reconciliation, and yet words are still being employed to divide and dehumanise. This reality necessitates a clearly articulated stance on the regulation of language. The thesis accordingly interrogates the current legal standards in relation to hate speech with reference to international law that binds South Africa and the constitutional standard set for the regulation of language and the prohibition of hate speech. Thereafter, the current and proposed legislative prohibitions on hate speech, the residual common law provisions governing expression and the regulation of language in the media are outlined and analysed. These legal frameworks are explored in terms of their content and their application in various fora so as to ascertain what the South African approach to hate speech prohibition is, whether it is consistent and, ultimately if it is indeed suitable to the South African experience and the realities of language. This thesis concludes that contemporary hate speech measures lack a coherent understanding of what hate speech entails and a general inconsistency in approach as well as application is found in the treatment of hate speech complaints in South Africa. This is explained through the fallibility of language as a medium to regulate expression and solutions are offered to not only taper current and proposed hate speech provisions but to also consider alternative forms of resolving hate speech complaints

- Description: The third sphere of government (Local Government) has been persistently clouded by unfavourable Annual Financial Statement (AFS) audit reports. This results in local government losing credibility and its stakeholders losing confidence in the institutions or municipalities. In-depth analysis of the root cause of this dilemma is an opportunity for the municipality to reorganise its house and redeem its dignity and credibility to its stakeholders through addressing the identified challenges. The importance of the study can be attributed to the need to investigate the root causes of unfavourable audit opinion and recommend possible remedies that can assist municipalities to improve their audit report outcomes which in turn will improve the confidence of its stakeholders. The primary objective of the study was to investigate variables that impact on the audit report outcomes on annual financial statements of the municipalities that are within Alfred Nzo District (AND) Jurisdiction, including Alfred Nzo District Municipality (ANDM). This was achieved through investigating the root causes of the audit report outcomes with specific focus on the relationship that exists between the management role and audit outcomes of the Alfred Nzo District Municipalities. This was measured by the municipality’s leadership, governance, internal controls and human capital management. Convenient sampling was used wherein 150 questionnaires (30 per municipality) were sent out to the selected employees in all the municipalities in the Alfred Nzo District. Out of the questionnaires that were sent out, 103 responses were received. These were analysed to draw findings, conclusion and recommendations. The empirical results of the study revealed that there is strong evidence that leadership, governance and human capital management have a positive influence on the municipality’s AFS audit report outcomes. It also revealed that there is overwhelming evidence that internal controls have a positive influence on the municipality’s AFS audit report outcomes. The study recommends how leadership, governance, internal controls and human capital management must be improved. It also provides future research recommendations to improve this study.

- Description: This think piece captures some of the thinking that emerged in and through the Southern African Development Community (SADC) Regional Environmental Education Programme research programme. This research programme emerged over a five-year period (2008–2012) and involved ten southern African teacher education institutions from eight countries (see ‘Acknowledgements’). The research programme sought to understand what contributions environment and sustainability education could make to debates on educational quality and relevance. Issues of educational quality are high on the national agendas of governments in southern Africa, as it is now well known that providing access to schooling is not a sufficient condition for achieving educational quality. Educational quality is intimately linked to the processes of teaching and learning, but the concept of educational quality is not unproblematic in and of itself. It is, as Noel Gough (2005) noted many years ago, an ‘order word’ that shapes the way people think and practise. Our enquiries during this research programme involved a number of case studies (that were reported on in the Southern African Journal of Environmental Education (SAJEE) in 2008, and are again reported on in this edition of the SAJEE), but the programme also involved theoretical engagement with the concept of educational quality and relevance. This think piece helps to make some of this thinking and theoretical deliberation visible. The author of this think piece was also the leader of the regional research programme and was tasked with synthesising the theoretical deliberations that emerged from the research design which were found to be useful for guiding interpretations and deliberation on more detailed case studies undertaken at country level.

- Description: Research methodology is significantly political and in this think piece I try to better understand the effect of this politicisation in the production of science. The main focus of the think piece is to identify the dominant methodological discourses and analyse them using techniques borrowed from post-structuralism. From this analysis, I suggest that methodological discourses are reproduced and normalised in much the same way as discourses of, for example, sexuality, and I give examples of this from my experience as a PhD student of environmental education. I also suggest that some transgressive methodologies, such as those associated with postmodernism or participatory research, despite purporting to empower, at times also disempower. Furthermore, all of the methodologies that I analyse are, in one way or another, ‘loaded’; they cloak their agendas. From this analysis, I move towards suggesting an alternative critical realist methodology for environmental education which is naked; its agendas are clearly stated, not least because this epistemology does not lend itself to deception. An important part of this critical realist conception of methodology is the idea of ‘meta-reflexivity’ in which truth is not vulgarly pragmatic or fideistic.

- Description: The objective of this study was to determine time budgets, blood urea content, total protein and body condition score as adaptive responses to seasonal dynamics by breeding Nguni cows and heifers reared on a sweetveld. Twenty four clinically healthy Nguni cows and heifers were selected for the study. The animals were grouped according to their parities namely: Parity 1 (n=5), Parity 2 (n=5), Parity 3-6 (old cows) (n=9) and in-calf heifers (n=5). Two separate experiments were conducted and running concurrently. In the first experiment time budgets (time spent walking, grazing, lying down, drinking water and browsing) of the cows and heifers were monitored for two consecutive days once a month, while in the second experiment blood samples were collected from the coccygeal vein once a month during weighing. Body condition scores were also determined during weighing times. Heifers maintained significantly (p0.05) of both blood urea nitrogen (BUN) (7.5±0.39 mmol/l) and TP (80.7±1.19 g/l) in November. All the animals had the least BUN levels in January (1.93±0.18 mmol/l) while the highest total protein (TP) (82.1±1.08 g/l) was recorded in February. All the animals showed distinct (p0.05) in most behavioural attributes in the cool-wet season. Heifers spent significantly (p0.05) body condition scores, amount of time spent browsing and drinking water. On the other hand, heifers (14.7±1.50%) and first parity cows (13.9±1.50%) traded-off most (p<0,05) of their time walking during the cool-dry season. Similarly heifers spent more time browsing (6.4±0.62%) forage plants (p<0.05) than all the cows during the cool-wet season. Grazing (r = 0.17) and standing (r = -0.18) were correlated (p<0.05) with all the behavioural attributes measured in this environment. It was concluded that seasonal dynamics in trade-off behaviour through time budgeting, maintenance of BUN and TP were necessary for the Nguni cows and heifers to maintain their body condition scores within a narrow range throughout the four seasons.

- Description: The estimation of variance components serves as an integral part of the evaluation of variation, and is of interest and required in a variety of applications (Hugo, 2012). Estimation of the among-group variance components is often desired for quantifying the variability and effectively understanding these measurements (Van Der Rijst, 2006). The methodology for determining Bayesian tolerance intervals for the one – way random effects model has originally been proposed by Wolfinger (1998) using both informative and non-informative prior distributions (Hugo, 2012). Wolfinger (1998) also provided relationships with frequentist methodologies. From a Bayesian point of view, it is important to investigate and compare the effect on coverage probabilities if negative variance components are either replaced by zero, or completely disregarded from the simulation process. This research presents a simulation-based approach for determining Bayesian tolerance intervals in variance component models when negative variance components are either replaced by zero, or completely disregarded from the simulation process. This approach handles different kinds of tolerance intervals in a straightforward fashion. It makes use of a computer-generated sample (Monte Carlo process) from the joint posterior distribution of the mean and variance parameters to construct a sample from other relevant posterior distributions. This research makes use of only non-informative Jeffreys‟ prior distributions and uses three Bayesian simulation methods. Comparative results of different tolerance intervals obtained using a method where negative variance components are either replaced by zero or completely disregarded from the simulation process, is investigated and discussed in this research.

- Description: Under the growing demand for marine fish resources, and the apparent and expected impacts of global climate change, there is a need to conduct long-term monitoring (LTM) to ensure effective management of resources and conservation of biodiversity. However LTM programmes often suffer from design deficiencies and fail to achieve their objectives. These deficiencies stem from the fact that insufficient consideration is afforded to the design phase, with programmes selecting methods that are not suitable to address the objectives, or are not cost-efficient, compromising the sustainability of the LTM. To facilitate the establishment of LTM programmes along the southern coast of South Africa, background research needed to be conducted to identify which methods were most appropriate for LTM of reef fish. This study presents a detailed field-based assessment of the suitability and cost-efficiency of monitoring methods for long-term monitoring of reef fish in the Agulhas Ecoregion of South Africa. The approach adopted to identify the method, or suite of methods most suited for LTM, involved (i) the selection of methods considered suitable for LTM, (ii) the individual assessment and optimisation of method performance, and (iii) the comparative assessment of the fish community sampled by the different methods. The most suited method(s) were then identified as those that provide the most comprehensive assessment of the fish community and had the highest cost-efficiency. The research was conducted between January 2008 and 2011 in the Tsitsikamma and Table Mountain National Park (TNP and TMNP, respectively) marine protected areas (MPAs) within the Agulhas Ecoregion. The methods selected included fish traps (FT), controlled angling (CA), underwater visual census (UVC), remote underwater video (RUV), baited RUV (BRUV) and remotely operated vehicles (ROV). The individual assessment and optimisation was conducted with the FT, UVC, RUV and BRUV methods. The assessment of the FT method aimed to identify the optimal soak time, and whether or not the size of the funnel entrance to the trap affected the catch. The results identified that larger funnel entrances caught more fish and soak times of 80 minutes produced the highest catches per unit effort. However the data were highly variable and the method detected few of the species typical of the region. Fish traps were also associated with high levels of mortality of fish post-release. The assessment of UVC strip transect method involved directly comparing the precision of data collected by researchers and volunteers using a novel double-observer technique (paired-transects). The results showed considerable error in both the volunteers and researchers data, however the researchers produced significantly higher precision data, compared to the volunteers. The distinction between researchers and volunteers was not evident in the data for the dominant species of fish. For all observers, the abundance of a species in the sample had a significant influence on its detectability, with locally scarce or rare species poorly detected. UVC was able to sample the majority of species typical of reefs in the region, however it appeared plagued by observer and detectability biases. The assessments of RUV and BRUV were conducted simultaneously which enabled the assessment of the effect of bait on the observed fish community. In addition the optimal deployment time for both methods to maximise species richness and abundance was determined. The results showed that BRUV, and to a lesser degree RUV, were able to effectively survey the reef fish community for the region with a 50 minute and 35 minute deployment time, respectively. Baited remote underwater video was especially good at detecting the invertebrate and generalist carnivores, and cartilaginous species. On the other hand, RUV was more effective at surveying the microinvertebrate carnivores. Remote underwater video was characterised by higher data variability, compared to BRUV, and was ultimately considered a less cost-efficient monitoring method. Comparative methods assessments were conducted during two field experiments with the FT, UVC and BRUV methods in the TMNP MPA, and the FT, CA, UVC, RUV, BRUV and ROV methods compared in the TNP MPA. The objectives of the comparison were to investigate differences in the fish communities observed with the different methods, and to determine the power of the data to detect an annual 10% growth in the fish populations over a period of five years. The results from the method comparison were in turn used to conduct the cost-benefit analysis to determine the efficiency of the different methods at achieving monitoring objectives requiring population data from multiple trophic and functional groups with the community, and from species of fisheries importance. The results indicated that FT, CA and ROV were ineffective at monitoring the reef fish community, although CA appeared to provide valuable data for the dominant fisheries species. Both CA and FT required minimal initial investment however, the variability in the data translated into high annual monitoring costs, as the required sampling effort was great. The ROV required the highest initial investment and was identified as the least cost-efficient method.

- Description: Under the growing demand for marine fish resources, and the apparent and expected impacts of global climate change, there is a need to conduct long-term monitoring (LTM) to ensure effective management of resources and conservation of biodiversity. However LTM programmes often suffer from design deficiencies and fail to achieve their objectives. These deficiencies stem from the fact that insufficient consideration is afforded to the design phase, with programmes selecting methods that are not suitable to address the objectives, or are not cost-efficient, compromising the sustainability of the LTM. To facilitate the establishment of LTM programmes along the southern coast of South Africa, background research needed to be conducted to identify which methods were most appropriate for LTM of reef fish. This study presents a detailed field-based assessment of the suitability and cost-efficiency of monitoring methods for long-term monitoring of reef fish in the Agulhas Ecoregion of South Africa. The approach adopted to identify the method, or suite of methods most suited for LTM, involved (i) the selection of methods considered suitable for LTM, (ii) the individual assessment and optimisation of method performance, and (iii) the comparative assessment of the fish community sampled by the different methods. The most suited method(s) were then identified as those that provide the most comprehensive assessment of the fish community and had the highest cost-efficiency. The research was conducted between January 2008 and 2011 in the Tsitsikamma and Table Mountain National Park (TNP and TMNP, respectively) marine protected areas (MPAs) within the Agulhas Ecoregion. The methods selected included fish traps (FT), controlled angling (CA), underwater visual census (UVC), remote underwater video (RUV), baited RUV (BRUV) and remotely operated vehicles (ROV). The individual assessment and optimisation was conducted with the FT, UVC, RUV and BRUV methods. The assessment of the FT method aimed to identify the optimal soak time, and whether or not the size of the funnel entrance to the trap affected the catch. The results identified that larger funnel entrances caught more fish and soak times of 80 minutes produced the highest catches per unit effort. However the data were highly variable and the method detected few of the species typical of the region. Fish traps were also associated with high levels of mortality of fish post-release. The assessment of UVC strip transect method involved directly comparing the precision of data collected by researchers and volunteers using a novel double-observer technique (paired-transects). The results showed considerable error in both the volunteers and researchers data, however the researchers produced significantly higher precision data, compared to the volunteers. The distinction between researchers and volunteers was not evident in the data for the dominant species of fish. For all observers, the abundance of a species in the sample had a significant influence on its detectability, with locally scarce or rare species poorly detected. UVC was able to sample the majority of species typical of reefs in the region, however it appeared plagued by observer and detectability biases. The assessments of RUV and BRUV were conducted simultaneously which enabled the assessment of the effect of bait on the observed fish community. In addition the optimal deployment time for both methods to maximise species richness and abundance was determined. The results showed that BRUV, and to a lesser degree RUV, were able to effectively survey the reef fish community for the region with a 50 minute and 35 minute deployment time, respectively. Baited remote underwater video was especially good at detecting the invertebrate and generalist carnivores, and cartilaginous species. On the other hand, RUV was more effective at surveying the microinvertebrate carnivores. Remote underwater video was characterised by higher data variability, compared to BRUV, and was ultimately considered a less cost-efficient monitoring method. Comparative methods assessments were conducted during two field experiments with the FT, UVC and BRUV methods in the TMNP MPA, and the FT, CA, UVC, RUV, BRUV and ROV methods compared in the TNP MPA. The objectives of the comparison were to investigate differences in the fish communities observed with the different methods, and to determine the power of the data to detect an annual 10% growth in the fish populations over a period of five years. The results from the method comparison were in turn used to conduct the cost-benefit analysis to determine the efficiency of the different methods at achieving monitoring objectives requiring population data from multiple trophic and functional groups with the community, and from species of fisheries importance. The results indicated that FT, CA and ROV were ineffective at monitoring the reef fish community, although CA appeared to provide valuable data for the dominant fisheries species. Both CA and FT required minimal initial investment however, the variability in the data translated into high annual monitoring costs, as the required sampling effort was great. The ROV required the highest initial investment and was identified as the least cost-efficient method. Underwater visual census was able to adequately survey the bony fish within the community, however it did not detect the cartilaginous species. Underwater visual census required a large initial investment and was not cost-efficient, as a many samples were required to account for the variability in the data. Remote underwater video provided a comprehensive assessment of the reef fish community, however it too was associated with high levels of variability in the data, compared to BRUV, reducing its cost-efficiency. BRUV provided the most comprehensive assessment of the reef fish community and was associated with the highest cost-efficiency to address the community and fisheries species monitoring objectives. During the course of this research stereo-BRUV has gained considerable support as an effective reef fish monitoring method. Although not tested during this research, stereo-BRUV is preferred to BRUV as it provides accurate data on the size of fish. However, the initial investment of stereo-BRUV is over three times that required for the BRUV. Although it is recommended that a baited video technique be used for LTM in the Agulhas Ecoregion, the choice between BRUV and stereo-BRUV will depend on the specific objectives of the programme and the available budget at the implementing agency.

- Description: This paper considers the application of GPU co-processors to accelerate the analysis of packet data, particularly within extremely large packet traces spanning months or years of traffic. Discussion focuses on the construction, performance and limitations of the experimental GPF (GPU Packet Filter), which employs a prototype massively-parallel protocol-independent multi-match algorithm to rapidly compare packets against multiple arbitrary filters. The paper concludes with a consideration of mechanisms to expand the flexibility and power of the GPF algorithm to construct a fully programmable GPU packet classification virtual machine, which can perform massively parallel classification, data-mining and data-transformation to explore and analyse packet traces. This virtual machine is a component of a larger framework of capture analysis tools which together provide capture indexing, manipulation, filtering and visualisation functions.

- Description: The thesis examines the Namibian labour dispute resolution system by undertaking a comparative analysis of South African and international labour standards. It describes the legal provisions that exist for the effective and efficient resolution of labour disputes through an alternative dispute resolution (ADR) system, which is given recognition in national labour legislation, and in a number of international labour standards and regional labour instruments. It argues for the provision of a proactive and expeditious dispute resolution system that helps to resolve labour disputes in the most effective and efficient manner, without necessarily having to resort to the courts. The study examines the provisions of relevant international labour standards on labour dispute resolution to ascertain their adequacy as part frameworks that apply to Namibia and South Africa’s obligation to provide ADR systems that respond to the needs of the labour relations community. It is argued that ratifying particular ILO conventions creates obligations to comply with their provisions, and to apply them in national legislation and in practice. It is further argued that by having ratified those international labour standards that provide for ADR, Namibia assumes specific obligations under international law, enjoining the country to provide the required ADR system of conciliation and arbitration, which is credible and trusted by disputants and the general public. A comparative approach is adopted, which relies on primary and secondary sources of data, thereby undertaking an in-depth content analysis. The focus of the comparison is on whether the South African ADR system can inform Namibia’s application of its newly adopted ADR system. South Africa has a labour dispute resolution system that has influenced Namibian labour law, prompting Namibia to borrow its ADR system from South Africa’s advanced Commission for Conciliation Mediation and Arbitration (CCMA). In this sense, it is submitted that there are fundamental similarities and differences in the two respective systems. Ideally, disputes should be resolved at conciliation level, resulting in the minority of disputes being referred to arbitration or the Labour Court. In terms of implementation, it is argued that despite the international obligation and commitment to provide and make available free and expeditious ADR services, there are gaps that exist between the legal framework regulating the ADR system and the application thereof in practice, making the attainment of effective and efficient labour dispute resolution difficult. Disputes should be resolved as quickly and informally as possible, with little or no procedural technicalities, and without allowing them to drag on indefinitely, offering immediate solutions instead. This is far from the reality of the situation. In contrast, the study found that although the Labour Act, 2007 and the South African Labour Relations Act (LRA) have brought statutory dispute resolution within the reach of the ordinary worker, these Acts may have compounded the problems relating to dispute resolution in the respective countries. The statutes in question have created sophisticated systems of dispute resolution in which most role players are seen as failing to operate as a result of the complex and technical processes of dealing with disputes. For this reason, the author proposes several remedial interventions that look to the future and the continued provision of fast, effective and user-friendly ADR services. Solving these problems and making effective and efficient labour dispute resolution a reality calls for renewed commitment from government and social partners and investment in appropriate human and financial resources. This requires a strong political will as well as concerted efforts from all role players in the labour relations community in the two respective countries.

- Description: This paper is a record of a unique intervention for enhancing the Undergraduate learning experience at Rhodes University. It will focus on the establishment of the project, the experiences encountered and lessons learned thus far. In April 2013, a vibrant team of 13 librarians embarked on a Personal Librarian Pilot Project at the Rhodes University Library. The Personal Librarian Programme is primarily directed at undergraduate students at Rhodes University. In an attempt to bridge the information literacy skills gap that exists between Senior School and University in South Africa, the idea behind this programme is that each incoming first year student is assigned a Personal Librarian who will remain that individual’s contact in the library throughout his/her academic career at Rhodes University. The project came about as a result of research exploring the perceptions of both students and lecturers in the Commerce Faculty at Rhodes University with regard to Information Literacy practices and needs (Gontshi, 2011). The study revealed and recorded a shortcoming in the Information Literacy ability of students between Senior School Level and University Level. It became clear that new University students were not aware of the important link between their academic studies and the Library which in turn suggested the need to make Rhodes University librarians and the role that they play in the academic world more obvious to these new students (Gontshi, 2011). The Personal Librarian Programme was devised to fill this need. The Librarians involved in this programme include staff from all sections of the Library: circulation, faculty liaison and bibliographic/technical services. The training needs of staff who did not work directly with students were identified and the relevant training provided. The staff from Circulation and Bibliographic/Technical services sections identified a need to advance their knowledge on the use of library from a users’ perspective. The training focused on the following: “Brainstorming a research topic with a student”; “Identifying relevant databases to conduct a research topic” and “Conducting a search on relevant databases for the research topic” – this included ‘different ways of devising an effective search technique’. The training ensured a good foundation for these librarians to develop their confidence to work with users. The project, modeled on a similar programme at the Yale University Library in America, was also a direct result of Rhodes University Library’s involvement in the Carnegie Research Libraries Consortium (2009 – 2011) and a ten-week internship in the United States, seven weeks of which were spent at Yale University.

- Description: With most employees in Engineering Small and Medium Enterprises (SME) now having access to their own personal workstations, the need for information security management to safeguard against loss/alteration or theft of the firms’ important information has increased. These Engineering SMEs tend to be more concerned with vulnerabilities from external threats, although industry research suggests that a substantial proportion of security incidents originate from insiders within the firm. Hence, technical preventative measures such as antivirus software and firewalls are proving to solve only part of the problem as the employees controlling them lack adequate information security knowledge. This tends to expose a firm to risk and costly mistakes made by naïve/uninformed employees. This dissertation presents an information security awareness process that seeks to cultivate positive security behaviours using a behavioural intention model based on the Theory of Reasoned Action, Protection Motivation Theory and the Behaviourism Theory. The process and model have been refined and verified using expert review and tested through action research at an Engineering SME in South Africa. The main finding was information security levels of employees within the firm were low, but the proposed information security awareness process increased their knowledge thereby positively altering their behaviour.
