- Description: Whilst arguing from a social realist perspective that knowledge matters in academic development (AD) curricula, this paper addresses the question of what knowledge types and practices are necessary for enabling epistemological access. It presents a single, in-depth, qualitative case study in which the curriculum of a science AD course is characterised using Legitimation Code Theory (LCT). Analysis of the course curriculum reveals legitimation of four main categories of knowledge types along a continuum of stronger to weaker epistemic relations: disciplinary knowledge, scientific literacies knowledge, general academic practices knowledge and everyday knowledge. These categories are ‘mapped’ onto an LCT(Semantics)(how meaning relates to both context and empirical referents) topological plane to reveal a curriculum that operates in three distinct but interrelated spaces by facing towards both the field of science and the practice of academia. It is argued that this empirically derived differentiated curriculum framework offers a conceptual means for considering the notion of access to ‘powerful’ knowledge in a range of AD and mainstream contexts.

- Description: In this thesis we consider nonholonomic Riemannian manifolds, and in particular, left- invariant nonholonomic Riemannian structures on Lie groups. These structures are closely related to mechanical systems with (positive definite) quadratic Lagrangians and nonholo- nomic constraints linear in velocities. In the first chapter, we review basic concepts of non- holonomic Riemannian geometry, including the left-invariant structures. We also examine the class of left-invariant structures with so-called Cartan-Schouten connections. The second chapter investigates the curvature of nonholonomic Riemannian manifolds and the Schouten and Wagner curvature tensors. The Schouten tensor is canonically associated to every non- holonomic Riemannian structure (in particular, we use it to define isometric invariants for structures on three-dimensional manifolds). By contrast, the Wagner tensor is not generally intrinsic, but can be used to characterise flat structures (i.e., those whose associated parallel transport is path-independent). The third chapter considers equivalence of nonholonomic Rie- mannian manifolds, particularly up to nonholonomic isometry. We also introduce the notion of a nonholonomic Riemannian submanifold, and investigate the conditions under which such a submanifold inherits its geometry from the enveloping space. The latter problem involves the concept of a geodesically invariant distribution, and we show it is also related to the curvature. In the last chapter we specialise to three-dimensional nonholonomic Riemannian manifolds. We consider the equivalence of such structures up to nonholonomic isometry and rescaling, and classify the left-invariant structures on the (three-dimensional) simply connected Lie groups. We also characterise the flat structures in three dimensions, and then classify the flat structures on the simply connected Lie groups. Lastly, we consider three typical examples of (left-invariant) nonholonomic Riemannian structures on three-dimensional Lie groups, two of which arise from problems in classical mechanics (viz., the Chaplygin problem and the Suslov problem). , Thesis (PhD) -- Faculty of Science, Mathematics (Pure and Applied), 2017

- Description: This article explores how Ishtiyaq Shukri’s The Silent Minaret critiques the limited and severely uneven forms of hospitality that characterise post-9/11 Britain. It also examines how the text gestures towards the possibility of a non-violent, inclusive cosmopolitanism. The piece begins by relating recent debates surrounding the “War on Terror”, as well as Britain’s decision to leave the European Union to the novel’s major concerns. It then turns to the novel, and summarises incidents in which the principal character, Issa Shamshuddin, is traumatised and harmed by the Islamophobia and anti-immigration policies evident in the London portrayed in the text. Next, it turns to an analysis of the strange and irreproducible rituals of Issa’s neighbour, Frances. The article concludes that that these unfollowable rituals posit how a truly cosmopolitan society would function.

- Description: The post-apartheid higher education transformation project is faced with the challenge of recruiting and retaining black academics and other senior staff. But when we shift the focus from participation rates to equality–inequality within historically white universities (HWUs), then the discourse changes from demographic equity and redress to institutional culture and diversity. HWUs invoke the need to maintain their position as leading higher education institutions globally, and notions of ‘quality’ and ‘excellence’ have emerged as discursive practices, which serve to perpetuate exclusion. The question then arises as to which forms of capital comprise the Gold Standard at HWUs? Several South African universities have responded to the challenge of recruiting and retaining black academics by initiating programmes for the ‘accelerated development’ of these candidates.

- Description: Pre-print , The traditional apprenticeship model of supervision in which the single scholar charts her individual research path is giving way to more collaborative learning environments. Doctoral programmes, in which communities of scholars work together, have become increasingly common. This study interrogated how being part of such a community enables the conceptual depth we expect at doctoral level. It draws on the notion of conceptual threshold crossing to make sense of the learning experiences of 28 education PhD scholars. Working in a community of doctoral scholars was found to have conceptual impact (i) when the community is supportive, (ii) encourages risk-taking and facilitates conversations across different issues and disciplines, (iii) when the scholars have to regularly articulate their position and (iv) because the programme structure enhances the likelihood of fortuitous encounters with theories and concepts.

- Description: The synthesis of four low symmetry A2B type Cu (III)triarylcorroles with meso-aryl substituents that provide electron donating (push) and withdrawing (pull) properties is reported, along with their structural characterization by NMR spectroscopy and X-ray crystallography. An analysis of the structure–property relationships in the optical and redox properties has been carried out by comparing their optical spectroscopy, electrochemistry, and spectroelectrochemistry to trends predicted in DFT and TD-DFT calculations. The results demonstrate that A2B type Cu(III)triarylcorroles are highly efficient catalysts for electrocatalyzed hydrogen evolution reactions (HERs) and that their reactivity can be modulated by changing the nature of the B-position meso-substituent.

- Description: Water plays a key role in all our lives and in South Africa epitomizes a space in which political inequalities have played themselves out with devastating consequences. The current ecological crisis demands new ways of engaging with ourselves, each other and nature. This research is an initial exploration on the use of a body-based creative movement approach within a transdisciplinary complex social-ecological systems researcher group. The research objective discussed in this chapter is to develop culturally relevant themes from professional Dance Movement Psychotherapy (DMP) training in the UK for application in a South African water resource management context. Interpretative Phenomenological Analysis was used to identify culturally relevant themes based on the recorded perceptions of the phenomenon of the training while it was taking place. The themes of: Awareness of Power and Difference; Therapeutic Adaptability; Sharing Leadership and Connecting with the Environment were identified. Artistic Inquiry was used to creatively reflect on the themes and add an embodied response to the discussion. The cultural adaptations of DMP can contribute to a more engaged and non-hierarchical collaboration between practitioners and the people and communities they serve, which would facilitate a therapeutic practice that works with both internal, external (and even transcendental) factors.

- Description: There is a growing interest in working with customary management (CM) systems to effectively manage benthic resources and small-scale fisheries. The underlying notion is that CM institution as territorial use rights in fisheries (TURFs) can be sufficiently adaptive and dynamic to create the local incentives that are necessary for promoting sustainable fishing practices and marine conservation more generally in a given region. This paper reviews the social opportunities and challenges of working with CM systems as a form of TURF, particularly in Oceania. A key conclusion is that policy makers and managers not only need to recognize natural interconnectivity in any one marine space, but also consider the social interconnectivity of stakeholders that covers customary TURFs. Only by recognizing and working with the existing social networks that overlay any given marine territory can the operational principles of CM (as reviewed in this paper) be effectively deployed for achieving some kind of bioeconomic efficiency and creating an equitable rights-based fisheries management system.

- Description: Descriptions of service-learning in the literature tend to position it as a powerful pedagogic tool as well as an exemplar of ‘best practice’ applicable across all disciplines and institutional contexts. Furthermore service-learning is couched as a moral imperative. In the South African context, this moral imperative is translated into policy pronouncements driving institutions of higher education to demonstrate responsiveness to the transformation needs of broader society. In this article, two departments, Philosophy and Environmental Science, at one university are used as case studies to interrogate what enables the uptake of service-learning as a pedagogic tool. Drawing on the work of Fairclough, this paper identifies the dominant discourses at play and considers how they constrain or enable the uptake of service-learning. We advocate for the infusion of service-learning in curricula, but argue that institutional culture, disciplinary values and the structure of knowledge impact on its uptake and should not be dismissed in the implementation process.

- Description: Pre-print , The PhD is the highest formal qualification and signifies a scholar’s rite of passage as a legitimate contributor of new knowledge in a field. Examiner reports make claims about what is legitimate in a thesis and what is not and thus articulate the organising principles through which participation in a field is measured. The authors analysed 39 examiners’ reports on 13 PhDs produced over a five-year period by scholars from the Higher Education Research doctoral studies programme at Rhodes University in South Africa. Drawing on aspects of Karl Maton’s Legitimation Code Theory (LCT), this study uses the dimensions of LCT:Specialisation and LCT:Semantics to explore what kinds of knowledge, skills and procedures and what kinds of knowers are validated in the field of Higher Education Research through the examination process. The study found that despite concerns in the literature about the a-theoretical nature of the Higher Education Studies field, examiners valued high-level theoretical and meta-theoretical engagement as well as methodological rigour. In addition, examiners prized the ability to demonstrate a strong ideological position, to use a clear doctoral voice, and to recognise the axiological drive of the field. The analysis showed that examiners were interested in strong contextualisation of the problem-spaces in higher education in South Africa but also commented positively on candidates’ ability to move from troubling an issue within its context to being able to abstract findings so as to contribute to the field as a whole.

Drawing on aspects of Karl Maton’s Legitimation Code Theory (LCT), this study uses the dimensions of LCT:Specialisation and LCT:Semantics to explore what kinds of knowledge, skills and procedures and what kinds of knowers are validated in the field of Higher Education Research through the examination process. The study found that despite concerns in the literature about the a-theoretical nature of the Higher Education Studies field, examiners valued high-level theoretical and meta-theoretical engagement as well as methodological rigour. In addition, examiners prized the ability to demonstrate a strong ideological position, to use a clear doctoral voice, and to recognise the axiological drive of the field. The analysis showed that examiners were interested in strong contextualisation of the problem-spaces in higher education in South Africa but also commented positively on candidates’ ability to move from troubling an issue within its context to being able to abstract findings so as to contribute to the field as a whole.

- Description: This chapter considers how engagement with decolonization history, theory and practice may provide an interesting future frame for Environmental and Sustainability Education (ESE). The chapter provides an overview of some of the key dynam-ics of decolonization thinking that are circulating at present, and considers particularly the problematique of absence and emergence. It argues for giving attention not only to critical analysis of colonization concerns (ie identification of absence), but also to expansive, emergent theories of learning which we might mobilise in environmental and sustainability education (ESE) out of our existing forms of being in order to re-imagine new becomings that are oriented to the common good (ie pro-cesses of emergence). In situating the argument within wider discourses around education and the common good, this chapter argues that decolonisation is a project that concerns us all (not only those in the global South), given the contempo-rary realities and geopolitics of resource flows, hypercapitalism, colonization by market logic, and the privatisation of the commons.

- Description: Streams and riparian areas are tightly coupled through reciprocal trophic subsidies, and there is evidence that these subsidies affect consumers in connected ecosystems. Most studies of subsidies consider only their quantity and not their quality. We determined the bidirectional exchange of organisms between the Kowie River and its riparian zone in South Africa using floating pyramidal traps (to measure insect emergence) and pan traps (to capture infalling invertebrates).

Deep wounds... left... in hearts and minds: South African public history

- Description: Public history practise in South Africa holds out much promise of further things to come. It can close the gulf between history and heritage. This chapter argues that the role of the public historian should not be conflated with the dynamics of the heritage sector, but suggests how trained academics can indeed put their skills to work in a society that is passionately interested in understanding itself and how its pasts created the present. The student movement sharply raised the image of universities in crisis, requiring a whole new, relevant curriculum and rethinking the ways that universities relate to their publics. Public historians can work towards creating invented spaces for co-production of knowledge, moving beyond the traditional oral history interview. The divide between academia and communities is huge and needs to be constantly tackled, providing access to the secluded information of the professional world. I suggest that due to their privileged place in society, many historians have been unable or unwilling to engage with the recovery agenda – the massive need for affirmation of African identity, capacity and culture. A handful of dedicated public historians do not fit this mould and have been exemplary in rolling up their sleeves and boldly engaging with the messy complications of dealing with non-academic communities to produce new forms of historical knowledge, based on inclusiveness.

- Description: This chapter describes Environmental and Sustainability Edu-cation (ESE) in South Africa against the backdrop of a chang-ing educational system. It discusses changing educational im-peratives in post-apartheid South Africa and how these have been interpreted and applied in three curriculum revisions in South Africa since 1994: Curriculum 2005, the Revised Na-tional Curriculum Statements and the Curriculum Assessment Policy Statement. The narrative also examines a changing pic-ture of teacher professional development in South Africa high-lighting how constructivist and social realist understandings of education, development and learning have entered the dis-course and influenced practice in South Africa. The chapter concludes with highlighting how a relational approach to learn-ing, as evident in ESE practices in South Africa, can help to avoid a pendulum swing between the dichotomies of compet-ing discourses.

Density-dependent effects on body size, Philopatry, and dispersal in the Damaraland mole-rat (Fukomys damarensis)

- Description: Population density may exert changes in a variety of behavioural and physiological characters in animals. However, the effects of density-dependence and dispersal are poorly studied in subterranean rodents due to the difficulties involved in observing such effects in wild populations. Using the cooperative breeding Damaraland mole-rat (Fukomys damarensis) as a model species, the effects of population density on body size, growth rates, group size, recruitment, philopatry and dispersal were investigated at two sites (one with low density and one with high density) in the Northern Cape of South Africa. Group size, litter size and the probability of recapture were independent of population density. However, individual body size, recruitment, dispersal rate and dispersal distance were density-dependent. Individuals were significantly larger, juveniles exhibited a significantly higher growth rate, and juvenile recruitment was significantly greater when population density was low. At higher densities, significantly more individuals were lost between capture events which may be indicative of increased rates of dispersal. Mean dispersal distances in mole-rats were reduced at higher densities and increased at lower densities. While both sexes dispersed equally, males were significantly more likely to join an established colony and females created new burrow systems. In addition, four times as many single females were found when population density was low. The apparent differences in the study populations may be attributed to variable annual rainfall or food availability. The greater annual rainfall at the high-density site may provide better habitat conditions and therefore result in an increase in the population density and an increased dispersal rate due to the relaxed ecological constraints such as reduced energetic costs to burrowing. However, the larger body size found at the low-density site may indicate that the available food at that location is of better quality. This study revealed that mole-rats were able to disperse over 1km and therefore a much larger study area would be required in capture-mark-recapture studies to ensure the recapture of the majority of dispersers. Lastly, a surprising find of this study was that females may survive a solitary existence for over two years while awaiting the arrival of a mate.
