- Description: Debate about the extent to which university education should serve industry is an important consideration for institutions of higher learning in a transforming South Africa, and particularly for those teaching would-be journalists. This issue can also be profitably analysed with reference to the current framework of the South African education authorities who argue that the quality of higher education institutions should be measured in terms of their “fit for purpose” to missions aligned to stakeholder interests in the transformation of the country as a whole. This criterion for quality assessment tends to focus on the educative processes within a university, but it can be argued that it ought to extend into the examination of the output consequences of journalism teaching. This would amount to not just fitness for purpose, but also achievement of purpose – and the latter including a creative and critical impact.

- Description: A good indicator of successful land redistribution cases has to be the continuation of viable productivity rates in their post-transfer periods. Continued productivity benefits all the stakeholders that are involved in the process. Unfortunately, negative productivity levels have been reported in numerous South African land redistribution transfers in recent years. A game theoretic perspective is adopted to illustrate and argue that cooperation among key stakeholders, which could be enforced through long-term contracts between land buyers, sellers and new owners, may lead to maintenance and higher productivity levels and other benefits within the country's land redistribution process.

Over 500,000,000 HIV viruses could fit the dot on top of this i. In the wrong environment HIV dies. In the right environment, it dominates. AIDS is dominating South Africa with all ready 2.4 million people infected, with estimates of 20% of the working population being infected within four years. South Africa has willingly opened itself to domination. This time, not colonial political oppression or the cruelty of racial apartheid, but domination by a virus all of us saw coming. The Ministry of Health welcomed the virus by failing to impart a practical and realistic National AIDS strategy. Instead, entertaining us with a R14.3 million play called Sarafina 2 and a discredited new cure for AIDS Virodene.

- Description: The extant academic literature in the field of regional International Relations has paid little attention to non-state actors’ organizational relations in building region-ness. Yet, the region offers sets of organizational relations outside, alongside, and as part of the formal regional state structures to do with gender, which offer insights into non-state regional relations and thus help to fill the lacunae in the field and facilitate understanding of the regional dynamic of international relations. This article examines how organizational relations of non-state actors in gender security play out in the Southern African Development Community (SADC) region. It highlights the shortcomings of the inter-governmental approach to international relations pursued by various scholars. Drawing on interviews with representatives of NGOs, governments, the SADC, and annual reports, as well as the academic literature, it argues for a socio-historical approach to understanding regional organization and transnationalism, which considers African agency in building region-ness.

- Description: Metabolic remodelling of the tumour microenvironment is a major mechanism by which cancer cells survive and resist treatment. The pro-oncogenic inflammatory cascade released by adipose tissue promotes oncogenic transformation, proliferation, angiogenesis, metastasis and evasion of apoptosis. STAT3 has emerged as an important mediator of metabolic remodelling. As a downstream effector of adipocytokines and cytokines, its canonical and non-canonical activities affect mitochondrial functioning and cancer metabolism. In this review, we examine the central role played by the crosstalk between the transcriptional and mitochondrial roles of STAT3 to promote survival and further oncogenesis within the tumour microenvironment with a particular focus on adipose-breast cancer interactions.

- Description: preprint , It is rare for a writer to make a literary impact with only one novel. It is even more unusual when that work is written by a novice author in his early sixties. Yet such is the case of R.L. Peteni, whose novel, Hill of Fools, was published by David Philip in South Africa in 1976, and internationally in the same year by Heinemann in the African Writers Series. Four years later, in 1980, the book was translated by the author into Xhosa as Kwazidenge and published by the Lovedale Press. Twenty years after initial publication, in 1996, there came a television version of Kwazidenge broadcast by the SABC, starring Willie Thambo and Amanda Quwe, though the locale was translated – in the bizarre logic of television – to an urban environment on the Cape Flats. The transposition, though pragmatic in terms of television demographics, destroyed much of the point of Peteni’s work, for Hill of Fools is South Africa’s first regional novel in English by a black writer. It is also the first novel in English by a Xhosa-speaker.

Art topples monuments: artistic practice and colonial/postcolonial relations in the public space of Luanda

- Description: Even though there have been very few modern and contemporary artworks in the urban space of Luanda in the years after independence in 1975—and especially after the end of the civil war in 2002—there are two works by Angolan artists that are of particular interest: the sculpture Mitologias II (1984) by António Ole (b. 1951) and the photographic series Redefining the Power (2011) by Kiluanji Kia Henda (b. 1978). Both works address the possibility of using contemporary art as a symbolic form of the replacement of power, since both are built on pedestals that had previously supported monuments of Portuguese colonial power. They might, therefore, be read as a form of substitution for monuments that would commemorate and celebrate independence or the end of colonialism. This article also discusses whether these two artworks can also be regarded as counter-monuments and this contributes to the discourse on the visual and material culture of Lusophone Africa.

Bread and honour: white working class women and Afrikaner Nationalism in the 1930s

- Description: Women have occupied a central place in the ideological formulations of nationalist movements. In particular, the figure of woman as mother recurs throughout the history of nationalist political mobilizations. In Afrikaner nationalism, this symbolic female identity takes the form of the volksmoeder (mother of the nation) icon, commonly assumed to describe a highly circumscribed set of women's social roles, created for women by men. The academic orthodoxy holds that middle-class Afrikaner women submitted to the volksmoeder ideology early on in the development of Afrikaner nationalism but that the working class Afrikaner women of the Garment Workers' Union (GWU) represented an enclave of resistance to dominant definitions of ethnic identity. They chose instead to ally themselves with militant, class-conscious trade unionism. This paper argues that Afrikaner women of different classes helped to shape the contours of the volksmoeder icon. Whilst middle class Afrikaner women questioned the idea that their social contribution should remain restricted to narrow familial and charitable concerns, prominent working class women laid claim to their own entitlement to the volksmoeder heritage. In doing so, the latter contributed to the popularization and reinterpretation of an ideology that was at this time seeking a wider audience. The paper argues that the incorporation of Afrikaner women into the socialist milieu of the GWU did not result in these women simply discarding the ethnic components of their identity. Rather their self-awareness as Afrikaner women with a recent rural past was grafted onto their new experience as urban factory workers. The way in which leading working class Afrikaner women articulated this potent combination of 'derived' and 'inherent' ideology cannot be excluded from the complex process whereby Afrikaner nationalism achieved success as a movement appealing to its imagined community across boundaries of class and gender.

This booklet provides profile 'snapshots' of the major companies, national and international, involved in World Cup 2010 construction projects. These 'snapshots' include a description of history and operations, profits for the 2006 financial year, executive and non-executive remuneration and state the specific 2010 contract awarded to each company. To give a broader picture of profitability in the construction sector, we have included other companies (in Annexure 1), that may not be involved in 2010 projects directly. We also provide information on the minimum wages for the civil engineering sector, which is contrasted to the remuneration packages of executives in the industry. Through this booklet, we aim to arm those involved in the struggle for decent work with information to be used for discussion, debate and action amongst workers; and contribute to the building of the independent knowledge of the working class. After all, 'knowledge is too important to be left in the hands of the bosses'.

- Description: Protein homeostasis relies on a balance between protein folding and protein degradation. Molecular chaperones like Hsp70 and Hsp90 fulfil well-defined roles in protein folding and conformational stability via ATP dependent reaction cycles. These folding cycles are controlled by associations with a cohort of non-client protein co-chaperones, such as Hop, p23 and Aha1. Pro-folding co-chaperones facilitate the transit of the client protein through the chaperone mediated folding process. However, chaperones are also involved in ubiquitin-mediated proteasomal degradation of client proteins. Similar to folding complexes, the ability of chaperones to mediate protein degradation is regulated by co-chaperones, such as the C terminal Hsp70 binding protein (CHIP).

- Description: In 1985, the Central Statistical Services and the Chamber of Mines ceased publishing a racial breakdown of mining industry employment. This marked the end of a statistical series that dated back for almost 100 years. Since 1985, there is no official series of racially segmented data for the mining industry, while the racial breakdown of employment in all other sectors of the economy was published up until 1992. From 1993, the Central Statistical Services introduced a new “Unspecified Race” category into its published employment data, making the identification of trends in employment and income by race less certain. The statistical information on racial issues in this submission must reflect these difficulties with the data. In respect of gold and coal mines that are members of the Chamber of Mines, the Chamber periodically has made available unpublished information on employment and total wages after 1985, grouped into “skilled employees” and “unskilled / semi-skilled employees.” Until about 1989, when legal barriers to the employment of blacks in skilled jobs were removed, the two Chamber categories reflect the old “White” and “Non-White” categories used by the Chamber before 1986. Since 1989, a small, but slowly increasing number, of skilled workers have been black, but this has not been taken into account in any of the statistics presented for the gold and the coal sectors. “Black” employment in the gold and coal mining industry thus refers to employees in Categories 1 to 8, the only groups for which the NUM currently bargains with Chamber member mines.

Since 1989, a small, but slowly increasing number, of skilled workers have been black, but this has not been taken into account in any of the statistics presented for the gold and the coal sectors. “Black” employment in the gold and coal mining industry thus refers to employees in Categories 1 to 8, the only groups for which the NUM currently bargains with Chamber member mines.

- Description: Models used to predict species’ potential distributions have been described as either correlative or mechanistic. We attempted to determine whether correlative models could perform as well as mechanistic models for predicting species potential distributions, using a case study. We compared potential distribution predictions made for a coastal dune plant (Scaevola plumieri) along the coast of South Africa, using a mechanistic model based on summer water balance (SWB), and two correlative models (a profile and a group discrimination technique). The profile technique was based on principal components analysis (PCA) and the group-discrimination technique was based on multiple logistic regression (LR). Kappa (κ) statistics were used to objectively assess model performance and model agreement. Model performance was calculated by measuring the levels of agreement (using κ) between a set of testing localities (distribution records not used for model building) and each of the model predictions. Using published interpretive guidelines for the kappa statistic, model performance was “excellent” for the SWB model (κ=0.852), perfect for the LR model (κ=1.000), and “very good” for the PCA model (κ=0.721). Model agreement was calculated by measuring the level of agreement between the mechanistic model and the two correlative models. There was “good” model agreement between the SWB and PCA models (κ=0.679) and “very good” agreement between the SWB and LR models (κ=0.786). The results suggest that correlative models can perform as well as or better than simple mechanistic models. The predictions generated from these three modelling designs are likely to generate different insights into the potential distribution and biology of the target organism and may be appropriate in different situations. The choice of model is likely to be influenced by the aims of the study, the biology of the target organism, the level of knowledge the target organism’s biology, and data quality.

- Description: Geochemical data and mapping from a Karoo flood basalt crater complex reveals new information about the ascent and eruption of magma batches during the earliest phases of flood basalt volcanism. Flood basalt eruptions at Sterkspruit, South Africa began with emplacement of thin lava flows before abruptly switching to explosive phreatomagmatic and magmatic activity that formed a nest of craters, spatter and tuff rings and cones that collectively comprise a crater complex >40 km2 filled by 9–18 km3 of volcaniclastic debris.

- Description: This article begins by discussing what Christo Doherty in his article "Trauma and the Conscript Memoirs of the South African 'Border War'," published in English in Africa 42.2 (2015), calls the "explanatory schema" for the analysis of "anti-heroic" conscript memoirs. At the centre of Doherty's schema is the concept of post-traumatic stress disorder (PTSD), with its satellite concerns of "trauma narratives" and the "victim-perpetrator." In contrast, my analysis of two memoirs hinges upon a concern with the contest between hegemonic and counter-hegemonic discourses of masculinity that prevailed in the 1980s. The memoirs I focus upon are two that are briefly discussed by Doherty - Rick Andrew's Buried in the Sky (2001) and Anthony Feinstein's Battle Scarred: Hidden Costs of the Border War (1998/2011). The aim of the article is to apply to the memoirs an analytic framework that does justice to a wider range of intra- and inter-masculine dynamics than can be accommodated by a trauma-centred analysis.

Cosmolocal orientations: trickster spatialization and the politics of cultural bargaining in Zambia

- Description: The spatialization of Africa is fraught, and places within Africa tend to be stereotyped by geographies of morality and simplistic rural/urban divides. Focusing on the spatial, cultural, and political bargaining of contemporary chiefs and cultural festivals in 21st-century Zambia, this article delinks cosmopolitanism and Afropolitanism from the city and associated attitudes of urbanity. Positioning place as a trickster character, it argues for a nuanced understanding of time-space imaginaries that refuses to bind people and identities to closed-down notions of place. In this article I propose the term cosmolocal, suggesting that the cosmolocal is an outward-engaging orientation that understands place as a profoundly discursive and situational process and that has the potential to exist anywhere. Many contemporary chiefs in Zambia embrace cosmolocalism, enabling them to escape the limitations of being viewed merely as custodians of culture who are limited to the space of the village framed historically as the warehouse of culture.

Cybersecurity: reducing the attack surface

- Description: Almost 60% of the world’s population has access to the internet and most organisations today rely on internet connectivity to conduct business and carry out daily operations. Further to this, it is estimated that concepts such as the Internet of Things (IoT) will facilitate the connections of over 125 billion ‘things’ by the year 2030. However, as people and devices are becoming more and more interconnected, and more data is being shared, the question that must be asked is – are we doing so securely? Each year, cybercriminals cost organisations and individuals millions of dollars, using techniques such as phishing, social engineering, malware and denial of service attacks. In particular, together with the Covid-19 pandemic, there has been a so-called ‘cybercrime pandemic’. Threat actors adapted their techniques to target people with Covid-19-themed cyberattacks and phishing campaigns to exploit their stress and anxiety during the pandemic. Cybersecurity and cybercrime exist in a symbiotic relationship in cyberspace, where, as cybersecurity gets stronger, so the cybercriminals need to become stronger to overcome those defenses. And, as the cybercriminals become stronger, so too must the defenses. Further, this symbiotic relationship plays out on what is called the attack surface. Attack surfaces are the exposed areas of an organisation that make systems more vulnerable to attacks and, essentially, is all the gaps in an organisation’s security that could be compromised by a threat actor. This attack surface is increased through organisations incorporating things such as IoT technologies, migrating to the cloud and decentralising its workforce, as happened during the pandemic with many people working from home. It is essential that organisations reduce the digital attack surface, and the vulnerabilities introduced through devices connected to the internet, with technical strategies and solutions. However, the focus of cybersecurity is often on the digital attack surface and technical solutions, with less of a focus on the human aspects of cybersecurity. The human attack surface encompasses all the vulnerabilities introduced through the actions and activities of employees. These employees should be given the necessary cybersecurity awareness, training and education to reduce the human attack surface of organisations. However, it is not only employees of organisations who are online. All individuals who interact online should be cybersecurity aware and know how to reduce their own digital and human attack surfaces, or digital footprints. This paper emphasises the importance of utilising people as part of the cybersecurity defense through the cultivation of cybersecurity cultures in organisations and a cybersecurity conscious society.

Danger and disease in sex education : the saturation of ‘adolescence’ with colonialist assumptions

- Description: The United Nations Development Programme’s Millennium project argues for the importance of sexual and reproductive health in the achievement of all Millennium Development Goals. Sex education programmes, aimed principally at the youth, are thus emphasised and are in line with the specific Millennium Development Goals of reducing the incidence of HIV and improving maternal health. In this paper I analyse recent South African sex education and Life Orientation (a learning area containing sex education) manuals. Danger and disease feature as guiding metaphors for these manuals, with early reproduction and abortion being depicted as wholly deleterious and non-normative relationships leading to disease. I argue, firstly, that these renditions ignore well-designed comparative research that calls into questions the easy assumption of negative consequences accompanying ‘teenage pregnancy’ and abortion, and, secondly, that the persistence of danger and disease in sex education programmes is premised on a discourse of ‘adolescence’. ‘Adolescence’ as a concept is always already saturated with the colonialist foundation of phylogeny re-capitulating ontogeny. Individual development is interweaved with collective development with the threat of degeneration implied in both. This interweaving allows for the instrumentalist goal of sex education in which social changes are sought through changing individuals’ sexual attitudes and behaviour.
