- Description: Publisher version , Given the high rate of intimate partner violence (IPV), understanding how counsellors talk about IPV and their interventions is important. The authors conducted narrative interviews with eight counsellors from non-governmental organisations (NGOs) working with IPV. Using narrative-discursive methodology, this qualitative study paid attention to the discursive resources that the participants drew upon. Two broad clusters of discursive resources and one contradictory (‘nurturing femininity’) discourse emerged. The first cluster engenders a sense of helplessness in the face of overwhelming power relations; the second enables the counsellors to foresee positive outcomes for their counselling. Implications for counselling include emphasising enabling discourses, highlighting multiplicities of gender, and wider-scale interventions.

- Description: The cultural and creative industries (CCIs) have been hailed as offering great potential to create jobs and to be socially inclusive. Since artistic success is defined by individual talent, or merit, the CCIs should be one sector that is especially open to, and appreciative of, social diversity in terms of race, class, cultural group and gender. However, as expected, recent studies in both the UK and the US have revealed that employment in the CCIs is heavily dominated by the middle classes, and is not as diverse in terms of other characteristics. Since the advent of democracy in South Africa in 1994, transformation of firm ownership, previously dominated by white people, to include more black, coloured and Indian/Asian-origin South Africans, has been an important part of achieving greater economic equality and social cohesion, as well as being more representative of the cultures of the majority of the population. Using data from a survey of 2400 CCIs firms in South Africa, this paper examines the extent to which the CCIs in South Africa have transformed in terms of ownership and employment. Comparisons are also made across the six UNESCO [(2009). Framework for cultural statistics. UNESCO Institute for Statistics. Retrieved from http://www.uis.unesco.org/culture/Pages/framework-cultural-statistics.aspx] “Cultural Domains” in terms of ownership, average monthly turnover and the number of full-time, part-time and contract employees. Results show some diversity in the industry, but significant differences between the Domains. Statistical analysis demonstrates that CCI funding policy in South Africa is sensitive to advancing the transformation agenda in that more transformed firms were shown to be more likely to have received some form of government grant as part of their income.

- Description: The visit of the botanical artist, Marianne North, to South Africa during 1882 to 1883, although frequently referred to, has not received much close attention; nor has her account of the visit, in her ‘Recollections of a happy’ life, been set against the actual conditions she would have encountered. This paper attempts to flesh out at least part of that visit, specifically the weeks she spent in the Eastern Cape Colony and, more particularly, her visits to Port Elizabeth, Grahamstown and Port Alfred. What were these three centres like at the time? Who were the people she mentions? Where did she stay? How do her observations tally with other accounts of the period?.

- Description: Attempted repetition of a reported synthesis of fenchene from fenchol has afforded, in high overall yield, a mixture shown by spectroscopic and elemental analysis to comprise a pair of discrete rotameric systems of a novel 2-endo-2′-endo-difenchyl sulfite ester. The kinetics of the formation of these dimeric rotameric systems (I and II) has been explored experimentally, using 1H NMR spectroscopic analysis, and theoretically at molecular and quantum mechanical levels. Construction of a theoretical model has permitted calculation of rate constants for each of the steps, while modelling of the transition state complexes corresponding to the rate-determining steps for the formation of the rotameric systems I and II has revealed their independent access to further sets of interconverting rotamers.

The nonlinear optical response demonstrated that the studied complex and the nanoconjugates exhibit higher excited state absorption cross-section compared to ground state absorption. Enhanced optical limiting performance was observed when complex 6 was conjugated to nanoparticles with 6CB-AuNPs (CB = covalent bond) showing the highest optical limiting threshold of 0.36 J cm−2.

- Description: Quantitative measures of student performance fail to provide insight into underpinning constraints and enablements to access in science in higher education. This case study of a science foundation course uses Legitimation Code Theory as a theoretical frame and acquisition of recognition and realisation rules as an analytical frame to provide a depth empirical account of student access and success. Results indicate that access to the powerful science knowledge in the production (science) context is dependent on students recognising and realising the knower code of the learning context, which requires of them to be independent and autonomous learners. Such access is not afforded when students prior (school) learning-context relativist code clashes with the required university learning-context knower code. It is argued that a focus on the learning context could be key in enabling access to students whose educational background does not align well with that of the higher education context.

- Description: A comparative study of the dosimetric features of α-Al2O3:C,Mg and α-Al2O3:C relevant to thermoluminescence dosimetry is reported. A glow curve of α-Al2O3:C,Mg measured at 1°C/s after beta irradiation to 1 Gy shows two subsidiary peaks at 42°C (labelled as I) and 72°C (II) and the main peak at 161°C (III) whereas a glow curve of α-Al2O3:C measured under the same conditions shows the main peak at 178°C (II′) and a lower intensity peak at 48°C (I′). Apart from these ones, there are several other peaks at temperatures beyond that of the main peak in both α-Al2O3:C,Mg and α-Al2O3:C. However, the latter are not included in this study. We report a comparative quantitative analysis of dose response and fading of peaks I, II and III of α-Al2O3:C,Mg and peaks I′ and II′ of α-Al2O3:C. Analysis shows that the dose response of peaks I and III is sublinear within 1–10 Gy whereas that of peak II is superlinear within 1–4 Gy followed by a sublinear region within 4–10 Gy. In comparison, the dose response of peak I′ is superlinear within 1–4 Gy followed by a sublinear region within 4–10 Gy whereas that of peak II′ is sublinear within 1–4 Gy followed by a superlinear region within 4–10 Gy. As regards to fading corresponding to 1 Gy, peak I is very unstable and fades within 300 s, peak II is more stable and takes up to 43200 s to fade. In comparison, peak III fades down to 30% of its initial intensity within 2400 s. Interestingly, between 2400 and 800 s, the intensity fades by 17% only. Regarding fading in α-Al2O3:C, peak I′ fades within 600 s whereas peak II′ shows an inverse fading behaviour up to 64800 s. The rate of fading for peaks I, II and III in α-Al2O3:C,Mg was found to decrease with increase in dose. However, no such behaviour was observed in α-Al2O3:C. The fading in both samples is discussed on the basis of a charge hopping mechanism.

- Description: Social science and public health research has pointed to, firstly, the challenges women face in terms of the management of menstruation and, secondly, to the negative symbolic associations made with the menstruating body. This research, however, seldom engages with philosophical issues relating to embodied subjectivity in order to explain and understand the trends noted. In this paper, we attempt to bridge the divide between feminist theory and current research on the menstruation-related challenges facing women today. We provide a feminist phenomenological account of menstruation in which women's shared bodily lived experiences of menstruation—the body as situation—are set within contexts that enable and/or restrain freedom—the body in situation. This account allows us to understand the universal and differentiated aspects of menstruation and menstrual management, thereby providing a nuanced picture of the interplay between the physical occurrence of menstruation, the symbolic associations made with menstruation, and the socio-material, historical and political conditions within which women live. Such an account, we suggest, should inform advocacy around public policy and institutional civic society that promotes the freedom of women to engage in important life projects, and ground public health interventions around menstruation related challenges.

- Description: Victims of crimes against humanity perpetrated during Kenya’s post-2007 conflicts may feel aggrieved by the International Criminal Court’s discontinuance of all Kenya cases without having found the suspects either culpable or non-culpable. Neither did the suspects benefit from acquittals. Unprecedentedly, Ruto and Sang’s charges were vacated at half-time. Cases against other suspects were withdrawn. Given the circumstances which led to the ICC’s intervention in the Kenyan situation, this paper argues that in lieu of either quantitative or qualitative studies, arguments of various proxy approaches for evaluating judicial performance, are problematic. Neither judicial independence, rule-compliance, community of purpose, nor even institutional design, adequately measure judicial performance. Besides interrogating limitations of using such proxies, the paper appraises the merits of constructing a modified version of the goal-based approach. It will demonstrate that by incorporating both process-oriented as well as strategic constituency models, a more dynamic evaluative methodology can be developed for measuring the ICC’s performance in the Kenya cases.

- Description: The Russian Wheat Aphid (Diuraphis noxia Kurdjumov, 1913) (RWA) is a serious pest of grain crops and is of considerable concern in South Africa, particularly in terms of barley grown specifically for the brewing industry. This paper highlights the effect of a small (50 ppm) increase in [CO2] on the growth rate of the four South African RWA biotypes on the SABBIErica barley cultivar. Controlled environment experiments revealed that the colony growth rate for RWASA4 was significantly lower than SA1 under ambient conditions as well as significantly lower than SA1, SA2 or SA3 under elevated CO2 conditions. The unexpected difference suggested an atypical, non-preferential feeding habit on SABBIErica, for RWASA4. The small RWASA4 colonies inflicted similar morphological damage to the significantly larger RWASA1 – RWASA3 biotype populations — indicative of potential hypervirulence under elevated CO2. The continuous feeding of RWASA biotypes causes damage to the transport system as well as substantial, catastrophic damage to mesophyll chloroplasts as well as mitochondria within the host plant's leaves. The TEM study revealed evidence of sequential/systematic degeneration of chloroplasts and mitochondria with continued aphid feeding, which we suggest is an indication of potential emergent hypervirulence under elevated CO2 conditions.

- Description: As networks have grown, so has the data available for monitoring and security purposes. This increase in volume has raised significant chal-lenges for administrators in terms of how to identify threats in amongst the large volumes of network traffic, a large part of which is often back-ground noise. In this paper we propose a framework for scoring and coding NetFlow data with security related information. The scores and codes are added through the application of a series of independent tests, each of which may flag some form of suspicious behaviour. The cumulative effect of the scoring and coding raises the more serious po-tential threats to the fore, allowing for quick and effective investigation or action. The framework is presented along with a description of an implementation and some findings that uncover potentially malicious network traffic.

- Description: South African Sign Language (SASL) is an understudied language with a rich and interesting phonology. For instance, while the language allows onsetless syllables, it does not allow codaless syllables, except in a small class of signs which do not include path movement. This article identifies and defines possible constraints on syllable codas in SASL. Using a video dictionary as data, we have coded handshapes at locations occurring at the onset and coda of the more common signs in the lexicon. In handshape, it has been found that the selected fingers may move to create different handshapes in the coda position, but that these coda handshapes are often [1], [5], [A], [Å] or [S], which are the unmarked handshapes of the non-dominant hand in asymmetrical two-handed signs (Sandler and Lillo-Martin 2006). Furthermore, the joint specification for the selected fingers can also vary in the coda position, but there appear to be strict limitations on which joint combinations are permitted in the onset-coda relationship. There are also constraints on coda location. The major body region can change within a single syllable, and the preferred body regions in the coda position are [body] and [H2]. It is evident not only that handshape and location constraints occur at the coda position, but that these constraints show patterns similar to coda neutralisation in many spoken languages.

- Description: Health data is important as it provides an individual with knowledge of the factors needed to be improved for oneself. The development of fitness trackers and their associated software aid consumers to understand the manner in which they may improve their physical wellness. These devices are capable of collecting health data for a consumer such sleeping patterns, heart rate readings or the number of steps taken by an individual. Although, this information is very beneficial to guide a consumer to a better healthier state, it has been identified that they have privacy and security concerns. Privacy and Security are of great concern for fitness trackers and their associated applications as protecting health data is of critical importance. This is so, as health data is one of the highly sort after information by cyber criminals. Fitness trackers and their associated applications have been identified to contain privacy and security concerns that places the health data of consumers at risk to intruders. As the study of Consumer Health continues to grow it is vital to understand the elements that are needed to better protect the health information of a consumer. This research paper therefore provides a conceptual threat assessment framework that can be used to identify the elements needed to better secure Consumer Health Wearables. These elements consist of six core elements from the CIA triad and Microsoft STRIDE framework. Fourteen vulnerabilities were further discovered that were classified within these six core elements. Through this, better guidance can be achieved to improve the privacy and security of Consumer Health Wearables.

- Description: Cheetahs (Acinonyx jubatus) typically prey upon the most available small to medium-sized (23–56 kg) antelope (Hayward et al., 2006). In Botswana, impala (Aepyceros melampus) and springbok (Antidorcas marsupialis), followed by steenbok (Raphicerus campestris) and duiker (Sylvicapra grimmia), are the prey species most frequently killed by cheetahs (Klein, 2007). Juvenile eland (Tragelaphus oryx), gemsbok (Oryx gazella), hartebeest (Alcelaphus buselaphus) and kudu (Tragelaphus strepsiceros) are also taken (Klein, 2007). The Northern Tuli Game Reserve (NOTUGRE) in eastern Botswana is naturally delineated by the nonperennial Shashe and Limpopo rivers in the east and south and has relatively porous game fencing along portions of the western and southern boundaries (Fig. 1) (Jackson, McNutt & Apps, 2012). Neither the fences nor the rivers restrict the movement of large carnivores such as cheetahs, lions (Panthera leo), leopards (Panthera pardus), spotted hyaenas (Crocuta crocuta) and African wild dogs (Lycaon pictus) onto neighbouring pastoral land (Jackson, McNutt & Apps, 2012). It is thus possible that cheetahs are feeding on livestock outside of the park. However, the diet of the cheetahs in NOTUGRE has not been evaluated. Our study serves to describe the diet of the cheetahs in NOTUGRE using both scats and kill sightings.

- Description: Is crime fiction the new 'political novel' in South Africa? Why did the apartheid censors disapprove of crime fiction more than any other genre? Crime fiction continues to be a burgeoning literary category in post-apartheid South Africa, with more new authors, titles and themes emerging every year. This book is the first comprehensive survey of South African crime fiction. It provides an overview of this phenomenally successful literary category, and places it within its wider social and historical context. The authors specialise in both literary studies and print culture, and this combination informs a critical analysis and publishing history of South African crime fiction from the nineteenth century to the present day. The book provides a literary lineage while considering different genres and sub-genres, as well as specific themes such as gender and eco-criticism. The inclusion of a detailed bibliography of crime fiction since the 1890s makes A Survey of South African Crime Fiction an indispensable teaching and study aid

- Description: Chimaeroid fishes (Holocephali) are one of the four principal divisions of modern gnathostomes (jawed vertebrates). Despite only 47 described living species1, chimaeroids are the focus of resurgent interest as potential archives of genomic data2 and for the unique perspective they provide on chondrichthyan and gnathostome ancestral conditions. Chimaeroids are also noteworthy for their highly derived body plan1,3,4. However, like other living groups with distinctive anatomies5, fossils have been of limited use in unravelling their evolutionary origin, as the earliest recognized examples already exhibit many of the specializations present in modern forms6,7. Here we report the results of a computed tomography analysis of Dwykaselachus, an enigmatic chondrichthyan braincase from the ~280 million year old Karoo sediments of South Africa8. Externally, the braincase is that of a symmoriid shark9,10,11,12,13and is by far the most complete uncrushed example yet discovered. Internally, the morphology exhibits otherwise characteristically chimaeroid specializations, including the otic labyrinth arrangement and the brain space configuration relative to exceptionally large orbits. These results have important implications for our view of modern chondrichthyan origins, add robust structure to the phylogeny of early crown group gnathostomes, reveal preconditions that suggest an initial morpho-functional basis for the derived chimaeroid cranium, and shed new light on the chondrichthyan response to the extinction at the end of the Devonian period.

- Description: E-Government deployments by stakeholders within the South African water service sector, provide certain benefits for the sector. While deemed beneficial and of considerable value, e-Government deployments and implementations in the water sector of local governments of South Africa have not always been successful. One important reason for e-Government failures, among several others, is the lack of coherent strategies, informed by key representing stakeholder views, to guide implementation and deployment of e-Government tools. Without strategies, it is highly likely that ICT integration will be conducted haphazardly. As a point of note, more than the deliverable (strategy document) that represents the output of the strategy development process, it serves more purpose to understand the process that results in the strategy. Importantly, understanding the process helps to account for the formed relationships between the various stakeholders that need to buy into the strategy. The research study develops an e-Government strategy formulation framework based on a systems thinking approach, intended to support the strategy formulation process of e-Government strategies – to underpin the effective integration, deployment and sustained use of ICT solutions for water service delivery at the local government level. A systems thinking approach is considered due to its emphasis on the strategy being informed by a holistic assessment. Where there is some knowledge about the processes by which a strategy is formulated – over time ideas may be derived on the types of processes that may produce efficient e-Government strategies. The research is conducted using the Design Science research paradigm. The Design Science paradigm is comprised of two processes – build and evaluate (Hevner et al., 2004). The build process, as related to this research concentrates on the progression through which the theoretical e-Government strategy formulation framework is derived. Weick’s (1989) theorizing approach is ascribed, supporting the design of the theoretical framework. In applying Weick’s theorizing approach, firstly, the lack of knowledge on how e-Government strategies should be formulated in South African local municipalities – is explicated in an intelligible manner. Once the problem is properly articulated, a trial and error selection process is undertaken of existing approaches on strategy formulation – thought to possess the potential to contribute to the development of an e-Government strategy formulation framework, suited to local governments in South Africa. With good reason, 10 (ten) strategy approaches are selected from, e-Government programmes in developed countries, Non-Governmental organizational strategy approaches, and business related strategy formulation approaches. Lastly, as all possible approaches that may contribute to the framework development process cannot be selected, criteria is specified to limit the number of possible selections. Furthermore, in deriving the framework, foundations for systematically dealing with unstructured problems, such as, strategy formulation are consulted. This foundation along with the research goals, informs the development of a template used to comparatively analyse the 10 selected approaches on strategy formulation. This analysis aids in revealing the components of an e-Government strategy formulation process. With the developed framework, the evaluation process of the design science research commences, seeking to determine the utility of the framework (suitability and shortcomings). The framework is applied to the procedural formulation of a strategy for a tentative e-Government project called MobiSAM, which aims to enhance citizen engagement with local government through the use of mobile phones. The strategy formulation application process in the project environment and local government reveals lessons that inform revisions to the framework. The e-Government strategy formulation framework, therefore represents a fundamental tool for e-Government strategy development in local municipalities, and may be customized to fit the requirements of varying local municipalities. , Thesis (PhD) -- Faculty of Commerce, Information Systems, 2017

- Description: Using the notion of “negative hermeneutics,” this chapter examines how Michiel Heyns’s novel Lost Ground draws on the heritage of the Sherlock Holmes stories. It argues that Heyns’s representation of contemporary South Africa necessitates a shift from the emphasis on the epistemological quests of nineteenth-century detective fiction to the “negative hermeneutics” and ontological concerns of postcolonial anti-detective fiction. An analysis of Lost Ground reveals direct intertextual and metatextual references to “The Silver Blaze,” yet the novel subversively presents a detective figure that is the antithesis of Holmes. Thus the chapter demonstrates how in postcolonial social and cultural contexts the ratiocinative process is hermeneutically inadequate and socio-political analysis comes to replace, or combine with, the feats of reason epitomized by Holmes.

- Description: Four low symmetric A2B meso-substituted Cu(III)corroles with electron withdrawing meso-aryl rings have been synthesized and characterized. A detailed analysis of the optical and redox properties has been carried out by comparing their optical spectroscopy, electrochemistry and spectroelectrochemistry to a series of DFT and TD-DFT calculations. A series of experiments demonstrate that these Cu(III)corroles can be used as highly effective catalysts for hydrogen evolution reactions (HERs). Moreover, when the number of fluorine atoms at B meso-position is increased, there is a marked enhancement in the catalytic ability of the corrole complexes, which demonstrates that modification to the structures of low symmetry corroles is a useful strategy for developing new HER catalysts.

- Description: Public health and rights-based approaches to abortion advocacy are well established. Feminists are, however, increasingly using a broader framework of ‘reproductive justice’, which considers the intersecting conditions that serve to enhance or hinder women’s reproductive freedoms, including their capacities to decide about the outcome of their pregnancies. Nonetheless, reproductive justice approaches to abortion are, conceptually, relatively under-developed. We introduce a reparative justice approach as a method of further articulating the concept of reproductive justice. We first explain how this approach can be used to conceptualise safe, accessible and supportive abortion as a key element of reproductive justice in relation to the injustice of unwanted or unsupportable pregnancies. Using Ernesto Verdeja’s critical theory of reparative justice and case studies of two countries (South Africa and Great Britain) where abortion is legal, we show how such an approach enables an analysis of reproductive justice within the specificities of particular contexts. We argue that both the rights-based legal framework adopted in South Africa and the medicalised approach of British law have, in practice, limited reparative justice in these contexts. We discuss the implications of reparative justice for abortion advocacy.
