- Description: This article engages with the autonomist Marxism of John Holloway from a feminist standpoint. The positions developed by this feminist critique are used to shed new light on the land occupations in contemporary Zimbabwe. Though sympathetic to his work, we argue that Holloway does not sufficiently address gender identity with specific reference to social reproduction and women. The notions of the commons and the process of commoning are consistent with Holloway’s autonomist framework and its complementarities to Silvia Federici’s Marxist feminist lens on the commons is highlighted. Against a tendency within autonomist and commoning theories, we argue for a pronounced identitarian politics as grounded in localised struggles undertaken by women as women. We privilege the significance of women asserting and revaluing their identities as part of a possible project of transformation. For us, struggling against and beyond what exists is invariably rooted in struggles within what exists (including identities).

- Description: publisher version , A number of approaches have been utilized in the prevention, management, and treatment of obesity, including, surgery, medication, diet, exercise, and overall lifestyle changes. Despite these interventions, the prevalence of obesity and the various disorders related to it is growing. In obesity, there is a constant state of chronic low‐grade inflammation which is characterized by activation and infiltration of pro‐inflammatory immune cells and a dysregulated production of high levels of pro‐inflammatory cytokines. This pro‐inflammatory milieu contributes to insulin resistance, type‐2 diabetes, cardiovascular disease, and other related co‐morbidities. The roles of the innate (macrophages, neutrophils, eosinophils, mast cells, NK cells, MAIT cells) and the adaptive (CD4 T cells, CD8 T cells, regulatory T cells, and B cells) immune responses and the roles of adipokines and cytokines in adipose tissue inflammation and obesity are discussed. An understanding of the crosstalk between the immune system and adipocytes may shed light in better treatment modalities for obesity and obesity‐related diseases.

- Description: Chapter 5 of the Tax Administration Act, which supplements the various fiscal statutes, empowers SARS to call for information on taxpayers, conduct audits, investigations and in certain instances to search premises and seize goods and records. For this purpose, taxpayers are required to keep proper books and records (see § 8.2 and § 4). The purpose of a tax audit is to verify the accuracy and timing of an assessment, but more specifically to ensure accuracy and full disclosure in terms of the law. In the event that an audit reveals non-compliance, criminal and/or civil charges may be initiated by SARS (see § 8.5).

- Description: Students Must Rise 98 Chapter 8 SASO and Black Consciousness, and the shift to congress politics I n 1960, demonstrators protesting against pass laws were killed and injured by police at Sharpeville. Soon afterwards, the apartheid government declared a state of emergency. Over 11 000 political activists were detained, and repressive new laws, police raids, arrests, bannings, and torture were used to crush political opposition to apartheid. The African National Congress (ANC) and Pan Africanist Congress (PAC) were banned, and many leaders of the ANC and PAC were arrested and imprisoned , and hundreds fled into exile. For many white South Africans, the rest of the 1960s were a time of economic boom, political calm, prosperity, and rising living standards. Some blacks took the opportunity to accumulate wealth, power, and privilege through the Bantustans that the apartheid government established as part of its separate development programme. For most blacks, it was a period of great economic exploitation, extensive political and social control, fear, and demoralisation. It was difficult to see how there could be any political challenge to white minority rule. Anti-apartheid organisations faced immediate repression. They also had to overcome black people’s fear and demoralisation, which stood in the way of mobilising opposition against apartheid. The emergence of the South African Students’ Organisation and Black Consciousness Despite many problems, the South African Students’ Organisation (SASO) was formed as an exclusively black university and college student organisation in 1968. It escaped immediate state repression, and developed a following among students at the Saleem Badat SASO and Black Consciousness, and the shift to congress politics 99 universities reserved for blacks. Thereafter, the ideology of Black Consciousness (BC) was developed and other BC organisations were formed, resulting in the BC movement. SASO saw its challenge as the ‘assertion, manifestation and development of a sense of awareness politically, socially and economically among the black community’.1 It emphasised black ‘group cohesion and solidarity’ as ‘important facets of Black Consciousness’, the need for ‘the totality of involvement of the oppressed people’, and for BC ‘to be spread to reach all sections of the black community’.2 SASO began community development, literacy, education, media, culture, and sports projects, which aimed to help black communities to determine and realise their own needs. They were seen as a means to win the trust of people and to educate and mobilise them.3 Projects instilled the idea of self-reliance, seen as important for achieving freedom, in members and communities. SASO created a favourable political climate for various organisations to emerge.

- Description: Publisher version , Pleurotus tuber-regium (Fr.) Singer (1951) is a unique sclerotium-forming edible and medicinal mushroom. Interestingly, both the sclerotium and mushroom are edible and are often used for curing various ailments. Previous studies have focused on the antimicrobial and antioxidant activity of the extracellular polysaccharide (EPS) from wild P. tuber-regium. There has been no report on the intracellular polysaccharide (IPS) of the wild mycelia, likewise there is very meager information on the improvement of the perceived potentials of P. tuber-regium. This research study analysed the EPS and IPS fractions of P. tuber-regium hybrid and mutant strains. The antimicrobial potential of the IPS and EPS fractions, their scavenging activity on 1, 1-diphenyl–2picryhydrazyl (DPPH) and Hydroxyl radicals were also determined. Both IPS and EPS fractions of P. tuber-regium hybrids and mutants showed increased DPPH and hydroxyl scavenging activity over the wild P. tuber-regium with an EC50 mostly 1 mg/ml. The antimicrobial activity of the IPS from a mutant strain had an IC50 of 15.6 mg/ml compared to the wild type (18.75 mg /ml). This study showed that selected mutant and hybrids of P. tuber-regium had increased radical scavenging activity indicating potentially increased biological activity that could offer increased benefit as a neutraceutical.

- Description: Publisher version , From Introduction: The understanding that the science, engineering, technology and mathematics disciplines (STEM) have a significant and directly causal role to play in economic productivity and innovation has driven an increased focus on these fields in higher education. Innovation in this context is a shorthand for the harnessing of the knowledge economy and the provision of products with novel significant ‘added value’. The assumption in both developed and developing economies alike is that STEM will drive national growth (World Bank 2002; UNESCO 2009), and this impacts on demands that universities provide competent graduates in sufficient numbers. However, exactly what ‘competency’ might mean in this context is open to debate.

- Description: Publisher version , We evaluated the bacteria occurring externally on Musca domestica and Chrysomya megacephala, the two most common synanthropic flies which may be found at many refuse sites throughout the world. Bacteria cultured from 10 specimens of each species were isolated, Gram-stained and examined microscopically, and divided into morphologically distinct ‘pseudospecies', to avoid excessive duplication of genetic identification. About 350 bp of the 16S ribosomalRNAgene was amplified from genomicDNAextracted from each ‘pseudospecies', sequenced, and bacteria identified using BLASTn. Nineteen different types of colony were identified from M. domestica, with Pseudomonas sp. and Swine Manure Bacterium SP14 being most abundant. Chrysomya megacephala yielded 15 distinct pseudospecies with total colony counts approximating to 10 000 from 10 plates, where 80 % of colonies were non-pathogenic Bacillus pumilus. A total of 18 species were identified genetically: three shared by the fly species; four unique to C. megacephala, and 13 unique to M. domestica. Half of these 18 species were pathogenic, two or three others were food spoilers and the rest were environmental or commensal bacteria from soil or plant matter. This study added three new pathogenic strains of bacteria and one new environmental strain to the list of bacteria reported to be vectored by these flies.

- Description: Time-resolved optical stimulation of luminescence has become established as a key method for measurement of optically stimulated luminescence from quartz, feldspar and α-Al2O3:C, all materials of interest in dosimetry. The aim of time-resolved optical stimulation is to separate in time the stimulation and emission of luminescence. The luminescence is stimulated from a sample using a brief light pulse and the emission monitored during stimulation in the presence of scattered stimulating light or after pulsing, over photomultiplier noise only. Although the use of the method in retrospective dosimetry has been somewhat limited, the technique has been successfully applied to study mechanisms in the processes leading up to luminescence emission. The main means for this has been the temperature dependence of the luminescence intensity as well as the luminescence lifetimes determined from time-resolved luminescence spectra. In this paper we review some key developments in theory and applications to quartz including methods of evaluating lifetimes, techniques of evaluating kinetic parameters using both the dependence of luminescence intensity and lifetime on measurement temperature, and of lifetimes on annealing temperature. We then provide an overview of some notable applications such as separation of quartz signals from a quartz–feldspar admixture and the utility of the dynamic throughput, a measure of luminescence measured as a function of the pulse width. The paper concludes with some suggestions of areas where further exploration would advance understanding of dynamics of luminescence in quartz and help address some outstanding problems in its application.

- Description: publisher version , Heat shock protein 90 (Hsp90) is of critical importance in the proper folding of numerous proteins, including those involved in cancer. Consequently, there is significant interest in the discovery and development of Hsp90 inhibitors as anticancer drugs. In this study, we investigated the ability of sargaquinoic acid (SQA) and selected naphthoquinone derivatives to inhibit Hsp90 function. SQA was isolated and purified from Sargassum incisifolium while the naphthoquinones were synthesised via a straightforward sequence incorporating a Diels-Alder reaction between benzoquinone derivatives and myrcene followed by coupling with substituted alkyl or arylamines. Hsp90 inhibition was assessed by a client protein degradation assay. At a concentration of 1µM, SQA showed almost complete inhibition of Hsp90 but only moderate antiproliferative effects (IC50 658µM) against a Hs578T breast cancer carcinoma cell line. Interestingly, the most potent synthetic aminonaphthoquinone inhibited Hsp90 function by 50% at a concentration of 1µM but showed much improved activity against the Hs578T cell line (IC50 0.32µM). Furthermore, unlike geldanamycin, none of the compounds tested upregulates Hsp70 suggesting that these compounds may bind to the C-terminal end of Hsp90.

- Description: A challenge facing higher education researchers, especially those new to the craft of research, is that of moving between theory and data effectively in order to mediate research findings clearly to readers. For postgraduate students and academics publishing their research, working with data and designing effective and fit-for-purpose methodologies can be a challenge. Moreover, this is not necessarily an easy area for supervisors and research mentors to assist with. In addition to researchers, practitioners working in academic development also need ways of using research – either empirical or conceptual – to augment their work with lecturers to improve teaching and learning. There are many handbooks that detail the differences between qualitative, quantitative and mixed-methods research. There are many theoretical texts to choose from. But there are few texts that offer researchers and those mentoring researchers insight into how methodology and theory connect in research studies, as well as practical tools to navigate the chaos of research, bringing theory and data into conversation in relevant and problem-oriented ways that can influence practice effectively. Karl Maton, in his introduction to this edited collection, argues that in spite of many claims within educational and social research for the need to connect research with theory more effectively, ‘the two frequently remain divorced or, at best, not on speaking terms’ (p. 1). The central premise of the book flows from this: we need to move beyond calls for more theory-informed research into education and society towards generating ways of demonstrating enactments of research that bring theory and research together meaningfully. The need for the research we publish to make clear its theoretical and methodological underpinning and enactments is crucial for effecting sustainable and meaningful change in practice within the field. This text, located within the growing field of Legitimation Code Theory (LCT) research, within the broader field of sociology of education, takes a generous step in that direction. Building on Maton’s 2014 text, Knowledge and knowers. Towards a realist sociology of education, this text delves into how LCT concepts – particularly in the dimensions of Specialisation and Semantics – can be enacted within educational research and practice.

- Description: Students’ ability to build knowledge, and transfer it within and between contexts is crucial to cumulative learning and to academic success. This has long been a concern of higher education research and practice. A central part of this concern for educators is creating the conditions that enable their students' deep learning, as this is an area of significant struggle for many students. Legitimation Code Theory, in particular the dimension of Semantics, is proving useful in examining the kinds of conditions that may be necessary for students to build disciplinary knowledge cumulatively over time. Using illustrative data from one case study, this paper suggests that the conceptual tools offered by Semantics can provide academic lecturers and academic development staff with a set of conceptual and analytical tools which can enable them to ‘see’ and understand the ways in which knowledge can be cumulatively acquired and used, as well as the possible gaps between what they are teaching and what their students may be learning. The hope is that these new insights will provide new directions for change in teaching and learning where these may be needed.
