- Description: Impact assessment is a requirement for development in many countries across the globe, seeking to inform the decision-maker as to the environmental, social and economic impact of an ongoing or proposed project. Socioeconomic impact assessment (SEIA) is a means of informing decision-makers as to the socioeconomic effects a project could have, or is having, thus contributing to informing adaptive management practices. However, the tendency of socioeconomic impact assessment to highly quantitative economic methods of analysis raises the question of whether the desired results are achieved by the process. The purpose of the research was to determine whether highly quantitative forms of economic analysis are suitable for measurement of impacts in a social context where distributive as well as net impact is important; to critically analyze the method utilized in achieving highly quantitative economic impact assessment results; and lastly to draw conclusions and make recommendations regarding the efficacy of monitoring processes used to inform adaptive management practices. The research was conducted by means of a case study focusing on three SEIAs carried out on the same entity, namely the Addo Elephant National Park. Managed by South African National Parks (SANP), it began expanding its borders in the early 2000s. Funded by the World Bank, SANP was required to carry out a comprehensive Strategic Environmental Assessment (SEA) in 2003 to ensure the expansion did not have negative environmental, social and economic repercussions, and where such consequences were unavoidable, to ensure that mitigation and management thereof was informed by useful monitoring exercises. Given the need for resettlement and issues of economic distributive concern raised in the 2003 SEA, the three socioeconomic impact assessments conducted from 2005 – 2010 as part of the ongoing monitoring exercises formed an ideal framework for answering the primary research questions. The findings indicate that despite consistent terms of reference, different assessors interpret mandates from the commissioning body in different ways, leading to varied applications of the same theory, some methodologically better than others. Economic multiplier analysis was found to be inadequate as a measure of the distributive effects of economic impact. Moreover, a lack of consistency, accountability and transparency in the monitoring process led to three sets of results that were incomparable over time and thus inadequate as a means to inform adaptive management practices. Asymmetries of and between power and expertise in the commissioning body and the assessors led to breakdowns of the assessment process in terms of accountability and integrity and resulted in a failure to properly define the scope of the study and measure the relevant indicators. The following recommendations were made: that the economic multiplier method be complemented by additional methods of analysis when utilized in disparate social contexts where distribution of economic benefit is important; that monitoring practices be systematized at an early stage of the process to ensure comparable results useful in informing ongoing management practices; and that what an assessment measures and how it measures it be clarified with reference to an objective source. Finally, the number of factors for consideration in any impact assessment means that measurement of the full picture suffers resource constraints, emphasizing the need for impact assessment oversight to recognize the deficiencies of the process whilst still acknowledging that ‘some number is better than no number’.

- Description: The Eastern Cape Provincial Administration has, since the promulgation of the Supply Chain Management Policy Framework in 2003, been challenged with the implementation of the said Policy.Some departments have progressed better than others, but all of the provincial departments have been challenged in one way or another.It was therefore, necessary to research the reasons for the erratic implementation process by the different departments. An analysis, based on answers provided by senior officials of the Eastern Cape Provincial Administration in an interviewing process, was needed to get an understanding of the challenges the departments are faced within the implementation process. In order to provide quality goods and services, this dissertation aims to evaluate the implementation process, provide insight to the challenges that the departments are faced with and offer recommendations on how to remedy these challenges. The lessons learned from this research study will assist the provincial departments to re-engineer their implementation processes and move forward to greater success and embracement of the Supply Chain Management policy Framework.

- Description: Modern botnet trends have lead to the use of IP and domain fast-fluxing to avoid detection and increase resilience. These techniques bypass traditional detection systems such as blacklists and intrusion detection systems. The Domain Name Service (DNS) is one of the most prevalent protocols on modern networks and is essential for the correct operation of many network activities, including botnet activity. For this reason DNS forms the ideal candidate for monitoring, detecting and mit-igating botnet activity. In this paper a system placed at the network edge is developed with the capability to detect fast-flux domains using DNS queries. Multiple domain features were examined to determine which would be most effective in the classification of domains. This is achieved using a C5.0 decision tree classifier and Bayesian statistics, with positive samples being labeled as potentially malicious and nega-tive samples as legitimate domains. The system detects malicious do-main names with a high degree of accuracy, minimising the need for blacklists. Statistical methods, namely Naive Bayesian, Bayesian, Total Variation distance and Probability distribution are applied to detect mali-cious domain names. The detection techniques are tested against sample traffic and it is shown that malicious traffic can be detected with low false positive rates.

- Description: The rapid expansion of networks and increase in internet connected devices has lead to a large number of hosts susceptible to virus infec-tion. Infected hosts are controlled by attackers and form so called bot-nets. These botnets are used to steal data, mask malicious activity and perform distributed denial of service attacks. Traditional protection mechanisms rely on host based detection of viruses. These systems are failing due to the rapid increase in the number of vulnerable hosts and attacks that easily bypass detection mechanisms. This paper pro-poses moving protection from the individual hosts to the Internet Ser-vice Provider (ISP), allowing for the detection and prevention of botnet traffic. DNS traffic inspection allows for the development of a lightweight and accurate classifier that has little or no effect on network perfor-mance. By preventing botnet activity at the ISP level, it is hoped that the threat of botnets can largely be mitigated.

- Description: The use of Network Telescope systems has become increasingly popular amongst security researchers in recent years. This study provides a framework for the utilisation of this data. The research is based on a primary dataset of 40 million events spanning 50 months collected using a small (/24) passive network telescope located in African IP space. This research presents a number of differing ways in which the data can be analysed ranging from low level protocol based analysis to higher level analysis at the geopolitical and network topology level. Anomalous traffic and illustrative anecdotes are explored in detail and highlighted. A discussion relating to bogon traffic observed is also presented. Two novel visualisation tools are presented, which were developed to aid in the analysis of large network telescope datasets. The first is a three-dimensional visualisation tool which allows for live, near-realtime analysis, and the second is a two-dimensional fractal based plotting scheme which allows for plots of the entire IPv4 address space to be produced, and manipulated. Using the techniques and tools developed for the analysis of this dataset, a detailed analysis of traffic recorded as destined for port 445/tcp is presented. This includes the evaluation of traffic surrounding the outbreak of the Conficker worm in November 2008. A number of metrics relating to the description and quantification of network telescope configuration and the resultant traffic captures are described, the use of which it is hoped will facilitate greater and easier collaboration among researchers utilising this network security technology. The research concludes with suggestions relating to other applications of the data and intelligence that can be extracted from network telescopes, and their use as part of an organisation’s integrated network security systems

- Description: The IP Multimedia Subsystem (IMS) is a telecommunication middleware platform with robust service features that enables the delivery of a wide range of services to mobile network subscribers. Network operators are encouraged to develop services from service building blocks in order to avoid redundancies by re-using existing functionality. In this environ-ment, operators must be able to control the service execution chain in order to prevent undesirable interactions from occurring between indi-vidual building blocks. It is also in their interests to provide subscribers with personalisation options so that they can modify service composi-tions and define their own preferences for how they would like their ser-vices to behave during live sessions. This paper describes a solution for these challenges that involves the storage of service information in an XDMS and allows operator staff and subscribers to manage this in-formation using the XCAP protocol. The ETSI-defined XCAP applica-tion usage named simservs was chosen to demonstrate an application usage that can be used to create service compositions in XML format. A prototype is described that uses components of the open source Mo-bicents project to verify the suitability of the design. This work is part of a larger effort aimed at modeling interaction management in the IMS through the use of a service broker that is part of an extended IMS ser-vice layer (EISL). The service broker's functional and structural architec-ture have not yet been standardised.

This project proposes the im-plementation of a testing framework based on numerous fuzz-testing tech-niques. The framework will allow a user to detect errors in applications and locate critical areas in the applications that are responsible for the detected errors. The aim is to provide an all-encompassing testing framework that will allow a developer to quickly and effectively deploy fuzz tests on an applica-tion and ensure a higher level of quality control before deployment.

- Description: This thesis examines the processes of policymaking in South Africa, as expressed through the shifts in income maintenance policy. The thesis focuses on the processes leading to the establishment of the South African Social Security Agency (SASSA), as its case study. SASSA is the institutional framework for the delivery of social grants. Our intention is to test the efficacy of what we have called ‘state learning’ in the South African context. Therefore, the overall aim of the study is to assess the capacity of the ‘state to learn’ in the process of policymaking as expressed through the shifts in social grant administration and the institutional framework of social welfare in South Africa. The subsidiary goals of the research includes mapping changes in the system of social grants administration since 1994 in order to assess the sources of the shifts in its institutional framework; to assess processes and responses within the state that result in policy shifts and the extent to which these can be considered dimensions of state learning; to assess the power of ideas in the policymaking process and to assess the influence of non-state agencies/actors in policy contestation and learning processes. This is essential, because social policy, especially welfare policy research in post-apartheid South Africa, has focused on the economic value of policies and not the political processes in policymaking. For the framework of analysis the study draws on theories of learning, especially at the organizational or institutional level. We start from the perspective that policymaking and implementation cannot be reduced to a neatly ordered schema (Lamb: 1987:6). Further, that policy change and policymaking are “iterative, haphazard, and highly political processes, in which the apparently logical sequences of decision-making, may turn out to be the reverse” (Lamb, 1987:6). This is mainly because state building is a complex affair and a contested terrain; policy learning and making are neither benign nor do they involve the state working in isolation (Sabatier, 1998). To understand processes of policymaking in South Africa, we rely on content analysis of primary and secondary materials or documents and in-depth interviews with key informants involved in the policy process. The documentary sources include records of parliamentary debates, green and white papers on social welfare, ANC party documents, presidential task force reports, newspapers, magazines and court judgments. The study reveals that the establishment of SASSA lends itself to the idea of ‘state learning’. Learning is indicated in South Africa by the capacity and ability of the state to stimulate ideas, debate ideas to establish ideational matrixes as well as paradigms that have informed the development of policy, take ideas and implement them to try and solve mismatches between the intention of the state and the outcomes and the ability of the state to produce policy.

A legal-comparative study of the interpretation and application of the doctrines of the sham and the alter-ego in the context of South African trust law: the dangers of translocating company law principles into trust law

- Description: This thesis analyses the doctrines of the sham and the alter-ego and their application to the law of trusts in South Africa. Following an initial examination of the historical development of the law of trusts in English law and the principles of equity law, the study focuses on the current legal status of the trust inter vivos in South Africa and the similarities to its English forerunner. The work traces the sham doctrine back to its origins in English law, where the term “sham” was first used in the context of fraud and dishonesty in cases involving matters arising from hire-purchase agreements, and explains how it gradually began to find its place in the law of trusts.

In terms of the alter-ego doctrine, the work highlights the birth of the principle in Australian law and the doctrine’s immediate reception into other common law jurisdictions and its resultant development. The growth, maturity and popularity of the doctrines are key to the thesis and, in the course of the investigation, the study provides a legal-comparative analysis of the treatment of the doctrines in the context of trusts against that in other common law countries. The study then shifts its focus to South Africa’s interpretation and application of these doctrines in trust law, and reveals the erroneous judicial development in which the courts have in some instances mistakenly replaced the sham doctrine with the company law doctrine of piercing the corporate veil or, in other instances, have erroneously conflated the two trust doctrines. The results highlight a breach of a fundamental rule observed overseas – the “no half way house” rule, which specifically cautions against South Africa’s chosen direction when allowing the lifting of a trust’s veil. The study closes with suggestions as to how the country could reconcile the problems underlined in the thesis by means of law reform, as well as offering practical advice for settlors, trustees and beneficiaries, the core of which is given in the handbook that accompanies this thesis.

- Description: This thesis analyses the doctrines of the sham and the alter-ego and their application to the law of trusts in South Africa. Following an initial examination of the historical development of the law of trusts in English law and the principles of equity law, the study focuses on the current legal status of the trust inter vivos in South Africa and the similarities to its English forerunner. The work traces the sham doctrine back to its origins in English law, where the term “sham” was first used in the context of fraud and dishonesty in cases involving matters arising from hire-purchase agreements, and explains how it gradually began to find its place in the law of trusts. During the exploration, the work highlights the cornerstone of the sham doctrine’s development, the Snook test, which in effect became the internationally accepted guideline for any sham trust enquiry. In terms of the alter-ego doctrine, the work highlights the birth of the principle in Australian law and the doctrine’s immediate reception into other common law jurisdictions and its resultant development.

- Description: Novel oxovanadium(IV) complexes of glycine, ʟ-alanine, 1-methylimidazole-2-carboxylic acid, imidazole-2-caboxylic acid and imidazole-4-carboxylic acid were synthesized and isolated in the solid state. The ligands and complexes were characterized by elemental analysis, melting point, NMR, IR and UV-vis spectroscopy. The IR studies showed that glycine and ʟ-alanine coordinate monodentately through the amine nitrogen whilst the imidazole-carboxylic acid derivatives assume a bidentate chelation. The electronic spectroscopic studies indicate distorted octahedral geometry for the oxovanadium complexes of amino acids and a square pyramidal geometry for oxovanadium(IV) complexes of imidazole carboxylic acid derivatives. The reaction of vanadyl (VO2+) with glycine, ʟ-alanine, imidazole-2-cabrboxylic acid, imidazole-4-carboxylic acid and 1-methylimidazole-2-carboxylic acid was studied in aqueous solution by pH-potentiometry under oxygen and carbon dioxide-free conditions. The data obtained from these titrations were used to calculate the protonation and stability constants. The results showed that all ligands are suitable for bidentate coordination in the formation of monomeric species although the solid state studies of the oxovanadium(IV) complexes of amino acids showed a monodentate coordination. The overall stability constants for the (VIVO)-ʟ-alanine system (log β120 = 18.27(6)), (VIVO)-glycine system (β120 = 17.22(6)), (VIVO)-imidazole-4-carboxyic acid (β120 = 11.38(8)), (VIVO)-imidazole-2-carboxylic acid (β120 = 11.62(6)) and (VIVO)-1-methylimidazole-2-carboxylic acid (β120 = 15.49(9)) were obtained. The calculations for the species distribution in the experimental pH range showed that the neutral bis-coordinated complexes are dominant over the biological pH range. The glucose uptake effect of oxovanadium(IV) complex of ʟ-alanine, imidazole-4-carboxylic acid, imidazole-2-carboxylic acid and 1-methylimidazole-2-carboxylic acid was investigated using 3T3-L1 adipocytes, Chang liver and C2C12 muscle cells at various concentrations. The compounds had significant glucose uptake on Chang liver cells only at a concentration of 0.1-10 μM whilst in the C2C12 muscle and 3T3-L1 cells the compounds showed little to no activity probably due to the lower concentrations employed as a result of the cytotoxicity of these compounds on these two cell lines.

- Description: FundaWethu is reading software that is designed to deliver reading lessons to Grade R-3 (foundation phase) children who are learning to read in a multilingual context. Starting from a premise that the system should be both educative and entertaining, the system allows literacy researchers or teachers to construct rich multimedia reading lessons, with text, pictures (possibly animated), and audio files. Using the design-based research methodology which is problem driven and iterative, we followed a user-centred design process in creating FundaWethu. To promote sustainability of the software, we chose to bring teachers on board as “co-designers” using the lesson authoring tool. We made the authoring tool simple enough for use by non computer specialists, but expressive enough to enable a wide range of beginners reading exercises to be constructed in a number of different languages (indigenous South African languages in particular). This project therefore centred on the use of designbased research to build FundaWethu, the design and construction of FundaWethu and the usability study carried out to determine the adequacy of FundaWethu.

- Description: Since the 1970s, the international economic system has become prone to the volatility and undue effects associated with booms and busts. This forty year period spanning the present has exhibited restrained growth and repressive economic development. Critical changes to the system are presented by the transition from "Fordism" to the post 1970s neoliberal regime and the globalization of world markets. Underpinning this transformation is an ideological shift towards free market capitalism and the adoption of "reduced form" market models. These "reduced form" models appear to hinder economic sustainability as their grounding in economics fails to account for real economic activity. This thesis aims to provide a more holistic perception of sustainability, one that provides a sound basis on which to develop sustainable economic policy. The Regulationist Approach presents the requisite understanding of economic sustainability required within this research. The inclusion of economic, historical and socio-political fields of research proposes a wider understanding of the political economy and sustainability. The application of the Regulation Approach to the South African economy illustrates many problem areas that require attention. The examination found that firstly, aggregate demand in the South African economy was unsustainable due to the debt driven nature of demand under the asset price bubble of the mid to late 2000s. Secondly, aggregate supply also proved unsustainable as government is failing to provide any substantive growth within important sectors of the economy such as education and the provision of general services. Furthermore, the adoption of inflation targeting in South Africa poses a barrier to sustained economic growth as it focuses singularly on price inflation. The "reduced form" model of inflation targeting fails to account for market failures and a number of vital indicators of sustainability most notably, debt levels and asset prices. The inclusion of these indicators, and financial stability more generally, are found to provide a more holistic and sustainable approach to macroeconomic policymaking.

However, much doubt exists over the extent to which this has been converted into appropriate classroom practice at the majority of under-resourced rural schools in the country. This article reports on a study which piloted a research tool which can be used to analyse teachers’ lessons, with the aim of gaining insight into the extent to which they integrate natural resource management issues. The research tool was based on Bernstein’s concept of classification and consisted of five indicators of natural resource management integration into Life Sciences lessons. The study contributes to the design of research tools that can be used to analyse and monitor the integration of environmental issues into teachers’ lessons. It also provides some insight into the environmental content of a sample of Grade 10 Life Sciences lessons at four rural underresourced schools in the Eastern Cape.

- Description: The southern African marine realm is located at the transition zone between the Atlantic and Indo-Pacific biomes. Its biodiversity is particularly rich and comprises faunal and floral elements from the two major oceanic regions, as well as a large number of endemics. Within this realm, strikingly different biota occur in close geographic proximity to each other, and many of the species with distributions spanning two or more of the region's marine biogeographic provinces are divided into evolutionary units that can often only be distinguished on the basis of genetic data. In this review, we describe the state of marine phylogeography in southern Africa, that is, the study of evolutionary relationships at the species level, or amongst closely related species, in relation to the region's marine environment. We focus particularly on coastal phylogeography, where much progress has recently been made in identifying phylogeographic breaks and explaining how they originated and are maintained. We also highlight numerous shortcomings that should be addressed in the near future. These include: the limited data available for commercially important organisms, particularly offshore species; the paucity of oceanographic data for nearshore areas; a dearth of studies based on multilocus data; and the fact that studying the role of diversifying selection in speciation has been limited to physiological approaches to the exclusion of genetics. It is becoming apparent that the southern African marine realm is one of the world's most interesting environments in which to study the evolutionary processes that shape not only regional, but also global patterns of marine biodiversity.

- Description: A critical review of the methodological approaches used to explore the impact of trade liberalisation in South Africa on growth and poverty in particular is preceded by a re-examination of key features of the theoretical debate on trade liberalisation and the controversies surrounding the associated empirical evidence. The appropriateness of the questions and concerns highlighted in the literature on ‘trade reform’ in South Africa are then considered, in the light of the recent emphasis on using trade policy to meet the country’s national and regional development goals. An important reason for the polarised and ideological debate on trade, growth and poverty has been the persistent view that a ‘free trade’ system is a relevant benchmark, and argues that the theory and evidence are not as compelling as proponents contend. Instead, alternative scenarios should be evaluated against those that are relevant for industrial, other development goals rather than relative to an unrealistic free trade ideal. In the debate,the broader state of play in multilateral, regional and bilateral trade negotiations and the associated obligations and pressures should also be appreciated. The dialogue on ‘trade reform’ in South Africa should move beyond simply characterising the debate as one between ‘free trade’ and ‘protectionism’.The appropriate question is rather how to manage trade sensibly, in order to allow for growth without creating balance of payment difficulties and policy space to promote the structural change necessary to create jobs.

(Azollaceae) has been ongoing in South Africa since the release of the first biological control agent on water hyacinth in 1974. This review provides an account of progress for the period from 1999. Post-release evaluations over the last three years have shown that, with the exception of water hyacinth, all of these problematic aquatic plants have been suppressed effectively using classical biological control. In eutrophic water bodies at high elevations that experience cold winters, an integrated approach, that includes herbicide application and augmentive biological control, is required against water hyacinth. The grasshopper Cornops aquaticum (Brüner) (Orthoptera: Acrididae: Leptysminae) has recently been released as a new agent for water hyacinth, and Megamelus scutellaris Berg (Hemiptera: Delphacidae) and Taosa longula Remes Lenicov (Hemiptera: Dictyopharidae) are being considered for release on water hyacinth. The longterm management of alien aquatic plants in South Africa relies on the prevention of new introductions of aquatic plant species that could replace those that have been controlled, and, more importantly, on a reduction in nutrient levels in South Africa's aquatic ecosystems.

- Description: Pyura stolonifera is a large solitary ascidian found in Africa, Australasia and South America. The taxonomic status of different populations of this species is disputed, especially since there is evidence for several distinct morphological and genetic units that point towards the existence of multiple cryptic species. While some researchers still recognize P. stolonifera as a single species, others treat the different populations as distinct species. Here, we present a revision of the P. stolonifera species complex based on the examination of samples from all regions where there are reliable reports of this taxon. We recognize four species that are both morphologically and genetically distinct, one of which is new to science and is formally described here. This species is morphologically distinct from the other three members of the species complex in terms of the colour and texture of the tunic, the arrangement of the gonads within the gut and the shape of the dorsal tubercle, among other characters. We name the new species Pyura dalbyi after Dr. J.E. Dalby Jr., whose research on its ecology and distribution provided the incentive for examining this species more closely.

We name the new species Pyura dalbyi after Dr. J.E. Dalby Jr., whose research on its ecology and distribution provided the incentive for examining this species more closely.

- Description: This journal reflects a diversity of environment and sustainability education research and viewpoints alongside two synthesis papers. Read as a whole and within a widely held ideal that diversity reflects resilience, the environment and education for sustainable development landscape in Africa might be said to be healthy and proliferating. But read against the pressure to produce tangible evidence of change on an African landscape of persistent climate variation and poverty, along with a widening gap between rich and poor, the picture remains challenging. These contrasting readings are notable at a time when we are looking towards the Association for the Development of Education in Africa (ADEA) Triennial in February, 2012, the Rio+20 Earth Summit in June 2012 and our own EEASA +30 conference in September 2012. The UN Decade of Education for Sustainable Development is characterised by a proliferation of education imperatives. These emerged as modern education in response to the issues of the day and now a modernity in deepening crisis.

A series of systematic case studies on the treatment of rape-related PTSD in the South African context implications for practice and policy

- Description: In 2009, South African police statistics revealed that more than 68 332 women were raped in the country. The evidence from independent researchers has shown that SAPS statistics are highly susceptible to under-reporting and the actual figure is more than double this amount. One pervasive feature of the phenomenology of rape is post-traumatic stress disorder (PTSD). PTSD is a highly debilitating condition with severe individual and societal costs. The condition takes a critical toll on occupational functioning, schooling and personal relationships and is associated with depression, suicide risk, self-harming behaviours and alcohol-abuse problems. The Ehlers and Clark (2000) cognitive model represents the most efficacious treatment for PTSD but the approach is severely under-utilised by South African practitioners working with sexual trauma. The reasons for such under-utilisation relate to a lack of exposure and training surrounding the model and concerns about the transportability of the treatment to a multi-cultural context. One method of addressing these barriers to treatment delivery is through systematic case-based research. Systematic case-based research offers a complementary means of refining theory and developing evidence-based practice in the context of a developing country. The method offers an intensive analysis and description of the particular phenomena under study within its real-life context. It allows the researcher to intensively examine and identify the specific aspects of the therapist’s responses and client’s reactions that contributed to significant change. Unlike efficacy studies, generalisability in case-study research is based on replication on a case-by-case basis and the creation of case law. This research study uses a systematic-case study approach to investigate the applicability of the Ehlers and Clark (2000) model in the treatment of rape-related PTSD in South Africa. The study aims to demonstrate the transportability of the model and develop a needed evidence base for service providers in the country. Seven women participated in the project and lent their treatment process to the research. The participants varied in terms of age, race, culture, socio-economic status and the nature of their sexual trauma. Through synoptic thematic analysis of their therapy process specific client-related personal aspects, client-related contextual factors and state-level factors were found to impede treatment delivery and implementation. The implications of these aspects for clinical practice and social policy are comprehensively discussed.
