- Description: A household survey of Helenvale Township in Port Elizabeth was conducted in order to gain an understanding of the strategies and activities that people in this poor community employ to sustain their livelihoods. The household profile, which entailed a survey of the household size, education levels and employment status was conducted. Dwelling units in terms of ownership, type, size, quality and building materials were also assessed. The income and expenditure of the Helenvale residents and community assets, as well as access to basic services were also assessed. The study found that the household size varied between 5 and 7 members. A more or less even distribution of the gender of household heads was noted, with 48 percent and 50 percent female male respectively. Among the HHs surveyed, no member had a higher qualification than Matric and quite a number were illiterate. Unemployment which stands at 54 percent was identified as the most serious problem plaguing Helenvale. A high level of home ownership (84 percent) was noted; of which 79 percent are formal dwellings and typically two-room structures of poor quality. Helenvale residents are largely dependent on child support grants as the major source of income. Casual jobs and disability grants are the other important sources of income identified. Human assets in the form of labour power are the most important assets that the community possesses. Physical assets are negligible, while financial ones are non-existent among all the respondents. Television and electric kettles are the most commonly owned appliances in the households. Basic services are readily accessible to the community, particularly water, health, refuse removal and sewage. Among the threats that the respondents identified, unemployment came to the fore as the biggest and major threat to households. Crime, teenage pregnancy and overcrowding are also considered as major threats, as are gangsterism and gambling violence. The study recommends the development of a long term plan for poverty alleviation. The creation of employment opportunities in the form of financing of small community projects which empower women and the youth is also recommended. All this should be underpinned by the expeditious delivery of housing.

- Description: It is estimated that each direct job in the automotive industry supports at least 5 indirect jobs in the global community, resulting in more than 50 million jobs to the global auto industry (Ellis, 2006). In South Africa the automotive sector, as an employer, is widely viewed to be second only to mining. In the automotive industry globally, it is being discovered that knowledge, as opposed to “data” or “information”, is becoming harder to locate as a knowledge-bleed is occurring due to the phenomenon of the “brain drain”, retirement of experienced professionals, changing work behaviours among the younger generations and the general lack of infusion of new talent into the South African automotive industry over the past decade (Liebowitz, 1999). This realisation has spawned a growing interest in the concept of knowledge management (KM). KM is the development of tools, processes, systems, structures and cultures explicitly to improve the creation, sharing and use of knowledge critical for decision making. The effective use of KM helps organisations to improve the quality of their decision making and correspondingly to reduce costs and increase efficiency (Kinicki and Kreitner, 2008). Most automotive Original Equipment Manufacturers (OEMs) have made some attempt at KM initiatives, and these attempts have been well-documented. However, among the automotive component suppliers, limited evidence exists of attempts at KM (Piderit, 2007). No standard KM application framework could be established in the literature for industry practitioners in automotive component manufacturers within the Eastern Cape. The aim of this research study is therefore to develop a framework for the application of KM in automotive component manufacturers within the Eastern Cape. The research consisted of a study of the knowledge management literature and the subsequent development of a knowledge management framework and empirical evaluation of the framework in the automotive component supply industry of the Eastern Cape. In conclusion the report presents a knowledge management framework which converts a company assessment to recommended corrective actions to be implemented and also presents the author’s findings, conclusions and recommendations derived from the study.

- 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. 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. 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: Lean manufacturing has seen its creators, Toyota, rise from insignificance in the middle of the previous century, to the biggest selling car manufacturer in the world today. Another Japanese car manufacturer, Honda, which has also been practising the principles of lean avidly during the last few decades, has also made huge strides towards becoming a dominant force in the car market. These Japanese companies‟ adoption of lean has seen many of their mass producing United States (US) and European counterparts struggle for survival. Maynard (2003:10) predicted that by the end of the decade, at least one of the „Big Three‟ auto makers in the US – Chrysler, Ford, and General Motors (GM) – would be forced to undertake significant restructuring to continue in operation. At the time of this writing all indications are that this prediction will come true. GM is in the process of major shareholding restructuring in an attempt to keep the company afloat, having run up insurmountable debts in the face of the current global economic downturn. Adopting the lean methodology has become a matter of necessity. The continued use of mass production methods alone is no longer viable; companies need to also employ lean methods intelligently in order to remain competitive. This study is regarded as a crucial endeavour to assist operations managers of manufacturing concerns in developing lean implementation strategies which will maximise the benefits to the organization.

- Description: The human being is commonly considered as being the weakest link in information security. Subsequently, as information is one of the most critical assets in an organization today, it is essential that the human element is considered in deployments of information security countermeasures. However, the human element is often neglected in this regard. Consequently, many criminals are now targeting the user directly to obtain sensitive information instead of spending days or even months trying to hack through systems. Some criminals are targeting users by utilizing various social engineering techniques to deceive the user into disclosing information. For this reason, the users of the Internet and ICT-related technologies are nowadays very vulnerable to various social engineering attacks. As a contribution to increase users’ social engineering awareness, a model – called SERUM – was devised. SERUM aims to cultivate social engineering resistance within a community through exposing the users of the community to ‘fake’ social engineering attacks. The users that react incorrectly to these attacks are instantly notified and requested to participate in an online social engineering awareness program. Thus, users are educated on-demand. The model was implemented as a software system and was utilized to conduct a phishing exercise on all the students of the Nelson Mandela Metropolitan University. The aim of the phishing exercise was to determine whether SERUM is effective in cultivating social engineering resistant behaviour within a community. This phishing exercise proved to be successful and positive results emanated. This indicated that a model like SERUM can indeed be used to educate users regarding phishing attacks.

A model for privacy-aware presence management in mobile communications

- Description: As humans we find communicating natural and compelling. Over the centuries we have created many innovations which enable and improve communication between people; during the past decade mobile phone networks have brought about a technological revolution in this area. Never before have people been so connected to one another. Today we have the ability to communicate with almost anyone, anytime, anywhere. Our increased connectivity and reachability also leads to new issues and challenges that we need to deal with. When we phone someone we expect an instant connection, and when this does not occur it can be frustrating. On the other hand it is equally disruptive to receive a call when one is busy with an important task or in a situation where communication is inappropriate. Social protocol dictates that we try to minimize such situations for the benefit of others nearby and for ourselves. This management of communications is a constant and difficult task. Using presence – which signals a person’s availability and willingness to communicate – is a solution to this problem. Such information can benefit communication partners by increasing the likelihood of a successful connection and decreasing disruptions. This research addresses the problem of staying connected while keeping control over mobile communications. It adopts a design-science research paradigm, with the primary research artifact being a model for privacy-aware presence management in mobile communications. As part of the model development knowledge contributions are made in several ways. Existing knowledge about the problem area is extended through a quantitative analysis of mobile communications management. This analysis uses a novel survey, collecting useful empirical data for future research. This includes how people currently manage their communications and what features they expect from a potential “call management” system. The examination and use of presence standards, as a foundation for the model, provides a comparison of the main presence technologies available today. A focus on privacy features identifies several shortcomings in standards which, if addressed, can help to improve and make these standards more complete. The model stresses the privacy of potentially sensitive presence information. A unique perspective based on social relationship theories is adopted. The use of relationship groups not only makes logical sense but also assists in the management of presence information and extends existing standards. Finally, the evaluation of the model demonstrates the feasibility of a practical implementation as well the ability to extend the model in next generation mobile networks. Thus the model presents a solid foundation for the development of future services. In these ways the proposed model contributes positively towards balancing efficient mobile communications with the need for privacy-awareness.

The review done showed that literature is replete with arguments critical of the dominant paradigm due to its top-down nature of communication. Scholars critical of dominant paradigm argue that participatory communication should be given a prominent role to ensure that stakeholders work in concert to realise the stated objectives of their development project. The study highlighted many contentious issues surrounding the nature and practices of participatory communication. It pointed out that the issues have played themselves out in literature in the form of different typologies of participatory practices, which were dealt with extensively in this study. The discussion of participatory communication in literature is also mindful of different models of communication and the space they occupy in participatory communication practices. In this study, there was a discussion of transactional communication models as depicted by Nair and White (1993:52) and Steinberg (1997:19). Both scholars emphasise that participatory communication will not achieve its stated purpose without mutual agreement of the parties in communication. They equally stress the recognition of the possible effects of some contextual factors which may have bearing on the prevailing nature of communication. A review of different communication tools used by participatory development communicator was given in the study. These different communication tools were discussed in view of how these tools can be used to advance participatory practice in a development project, especially with reference to the project examined in this study. Using qualitative research method, different and appropriate interview methods such as semi-structured, focus group and post-survey interviews were used to collect data from the respondents in this study. The analysis and discussion of the data revealed that different challenges on the ground could affect participatory communication practices in a development project. With regard to the project examined in this study, the analysis showed that there is a weak stakeholder relationship, especially stakeholders identified in this study as field officers. The study highlighted that stakeholders such as the agricultural extension officers and animal health technicians are not very active in the implementation process of the project. Some of the reasons pointed out is the fact that the secondary stakeholder such as the Provincial Department of Agricultural (PDoA) to which these field officers belong is not playing active role in ensuring that they complement the efforts of other field officers such as the IDC representatives. The second reason is the fact that the participatory focus of the project was not properly communicated to the beneficiaries. This also transpired in their inability to reflect participatory practice in their relationship with the beneficiaries and other stakeholders of the project. Other challenges, among others, as pointed out in the analysis showed that participatory communication practice requires expert personnel to be successful. In the case of the project examined, apart from the fact that there is shortage of manpower to handle the challenges mentioned in the study, there is no communication expert among the few active personnel in the field. The findings of this study showed that there was no clear role and identification of responsibilities let alone coordination of all actors involved in the project. Through the selected case study, this study has not only provided avenue to explore both theoretically and practically participatory communication, but has added to participatory communication discourse that there is no easy answer to challenges field officers encounter in practice. This is the reason the different participatory practices characterising nature of the project this study has investigated was given.

- 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: Psychobiographies offer the illuminating experience of uncovering the story of an individual’s life through the lens of a psychological theory. Psychobiographies offer the chance to gain a deeper understanding of what makes that individual unique. This study aimed to explore and describe the emotional intelligence of Archbishop Emeritus Desmond Tutu according to Goleman’s (1998) theory of Emotional Intelligence. Tutu was chosen as a subject for this study because of his extraordinary life and accomplishments, and because he is regarded as a prominent figure of moral leadership in South Africa. A qualitative psychobiographical research method was utilised. Data was collected from both primary and secondary sources to enhance internal validity, and was then analysed according to Miles and Huberman’s (1994) approach. The findings suggest that Tutu applied all of the twenty five emotional intelligence capacities during his life, and that at times, some were used more extensively than others. This study is groundbreaking in that it is the first psychobiography on Desmond Tutu, and it is the first psychobiography undertaken at the University of Fort Hare. Psychobiographies offer an opportunity to evaluate the psychological theory which is applied. It was found that Goleman’s (1998) theory of Emotional Intelligence is supported by this study.

- 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: Biological control against water hyacinth, Eichhornia crassipes (C. Mart.) Solms (Pontederiaceae), salvinia, Salvinia molesta D.S. Mitch. (Salviniaceae), water lettuce, Pistia stratiotes L. (Araceae), parrot's feather, Myriophyllum aquaticum (Vell.) Verdc. (Haloragaceae), and red water fern, Azolla filiculoides Lam. (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.

(Salviniaceae), water lettuce, Pistia stratiotes L. (Araceae), parrot's feather, Myriophyllum aquaticum (Vell.) Verdc. (Haloragaceae), and red water fern, Azolla filiculoides Lam. (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.

A review of the performance of Botswana citizen building contractors
- Authors: Muche, Freeman Hansungule
- Date: 2011
- Subjects: Contractors , Building -- Botswana , Construction industry -- Botswana

- Description: Botswana was left underdeveloped in 1966 when it gained its independence from Great Britain. However, with the discovery of diamonds in the late 1970s, the economy of the country changed and two decades later the construction industry had experienced phenomenal growth. A growth propelled by the dominance of foreign contractors and the few citizen contractors available at the time resulted in a competitive environment in the industry. However, citizen contractors were unable to compete on the same level with their foreign counterparts, which was attributable to various factors such as a lack of resources and of business and technical experience. Being a major player in the construction industry, and realising the need to equip and encourage its own base of citizen contractors to actively participate in construction activities, the government of Botswana adopted new measures and policies that were meant to address the imbalances in the construction industry much to the advantage of citizen contractors. The rationale behind this study is to investigate the performance of citizen building contractors following the introduction of preferential procurement policies by the government of Botswana. This research study adopted the descriptive and analytical survey method which entailed the use of questionnaires and a review of the related literature for gathering relevant data. The sample strata included building contractors, consultants, and clients in the Botswana construction industry in Gaborone, Francistown, Selebi-phikwe, Maun, Serowe, and Lobatse. The empirical findings revealed that there is indeed a need to review some of the government assistance programs for citizen contractors in order to avoid the abuse of government resources and to further increase the citizen contractor’s knowledge base, skills, resources and capacity through mentorship and workshops. vi It is therefore incumbent upon government to protect those beneficiaries who genuinely require such assistance by critical assessment of the ineffective policies for the benefit of the whole industry

- 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.

- 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.

- Description: Good communication and maintaining effective relationships within a school community are essential for achieving high academic standards. The aim of effective communication between teachers and learners is to elicit and ensure behaviour that will enhance the learning process. It is therefore important that teachers relate to learners in a sensitive manner when they communicate their knowledge (Bingham and Sidorkin 2004, 5). Sotto (2007, 96) further contends that teachers‟ communication styles reveal their core attitude towards learning and that the success of their teaching will be partially determined by how effectively they communicate. Many schools are experiencing disciplinary problems, low teacher and learner expectations, a breakdown of the social order, and a high incidence of academic failure. Bingham and Sidorkin (2004, 5) explain the above-mentioned problems as symptoms of a breakdown in communication between educators and learners. Once relationships in a school have been jeopardised, it becomes increasingly difficult to achieve high academic standards. It is therefore essential that educators create meaningful interactions in an environment in which all individuals can develop to their full potential. The National Education Policy Act No. 27 of 1996 (Education Labour Relations Council 2003, A- 4) advocates the enhancement of quality education and innovation through systematic research and development. The principles contained therein are directed towards enabling the education system to contribute to the full development of each learner, respecting each learner‟s right to freedom of thought, opinion and expression within a culture of respect for teaching and learning. The establishment and strengthening of relationships in a school will contribute to improved academic achievement.

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.
