- Description: The majority of women in the world - women workers - have not only suffered from exploitation by the bosses, they also face oppression as women in society and from their husbands and partners at home. According to the 1996 Human Development Report, of the 1.3 billion people living in poverty in the world, 70% are women. Twice as many women as men cannot read or write, and girls are 60% of the 130 million children who have no access to primary education. Women produce half of the world’s food but own around 1% of the world’s land. The number of rural women living in poverty has increased by 50% in the last twenty years, compared to 3% for men. Women also represent the highest percentage of the unemployed. The problems of women workers are not personal, individual problems. They are social problems which women suffer as members of this society, as workers and as women. So, if we want to address and work towards solving women workers’ problems, we have to tackle them as part of the problems of the whole society.

- Description: Lantana camara L. (Verbenaceae) is one of the most problematic plant invaders in South Africa and has been targeted for biological control for over 50 years. Essential oil constituents which often change in response to insect herbivory are reported to play a crucial role in plant-insect interactions. However, nothing is known about the chemical profiles of essential oils of L. camara varieties in South Africa and how this changes under herbivory. Therefore, essential oils were collected using hydrodistillation from undamaged and insect-damaged leaves of four L. camara varieties and analysed using gas chromatography-mass spectrometry to elucidate their chemical profiles. A total of 163 compounds were identified from the undamaged leaves of the various L. camara varieties. Feeding by the biocontrol agent Falconia intermedia Distant (Hemiptera: Miridae) resulted in changes in the quality and quantity of chemical constituents of the essential oils. Only 75 compounds were identified from the insect-damaged leaves of L. camara varieties. Terpenes were the major components across the varieties, while caryophyllene, hexane, naphthalene, copaene and a-caryophyllene were common in all the varieties tested from both undamaged and insect-damaged leaves. Results from this study indicated the chemical distinctiveness of the Whitney Farm variety from other varieties. The changes in chemical concentrations indicated that feeding by the mirid on L. camara varieties causes an induction by either reducing or increasing the chemical concentrations. These inductions following the feeding by F. intermedia could be having a negative impact on the success of biological control against L. camara varieties. However, the focus of this paper is to report on the chemical baseline of L. camara varieties. Hence, comparisons of chemical compound concentrations of L. camara essential oils tested and the feeding-induced changes with respect to their quality and quantity are discussed.

- Description: Due to the increased interest in their application in the treatment of infectious diseases, boron-containing compounds have received a significant coverage in the literature. Herein, a small set of novel cinnamoly-oxaborole amides were synthesized and screened against nagana Trypanosoma brucei brucei for antitrypanosomal activity. Compound 5g emerged as a new hit with an in vitro IC50 value of 0.086 μM against T. b. brucei without obvious inhibitory activity against HeLa cell lines. The same series was also screened against other human pathogens, including Mycobacterium tuberculosis, the causative agent of tuberculosis (TB), for which moderate to weak activity (10 to >125 μM) was observed. Similarly, these compounds exhibited moderate activity against the human protozoal pathogen Trichomonas vaginalis with no observed effect on common microbiome bacterial species. The cross-species inhibitory activity presents the possibility of these compounds serving as broad-spectrum antibiotics for these prevalent three human pathogens.

- Description: Hydraulic engineering infrastructures, such as reservoirs, dikes, breakwaters, and inlet closures, have significantly impacted ecosystem functioning over the last two centuries. Currently, nature-based solutions are receiving increasing attention in hydraulic engineering projects and research programs. However, there is a lack of reflection on the concomitant, fundamental changes occurring in the field of hydraulic engineering, and coastal engineering in particular, and what this could mean for sustainability. In this article, we signal the shift from conventional to ecosystem-based hydraulic engineering design and characterize this in terms of four continua: (i) the degree of inclusion of ecological knowledge, (ii) the extent to which the full infrastructural lifecycle is addressed, (iii) the complexity of the actor arena taken into account, and (iv) the resulting form of the infrastructural artefact. We support our arguments with two carefully selected, iconic examples from the Netherlands and indicate how the stretching ideals of ecosystem-based engineering could engender further shifts towards sustainability.

- Description: In June 1959 there were widespread riots and disturbances in the Durban African area of Cato Manor. The fundamental causes were socio-economic; arising from such factors as poor living conditions and widespread poverty. But it was the exhaustive beer-raids on illegal stills that provided a flashpoint. It was illegal for Africans to brew their own beer; instead they were obliged to purchase it from the municipal beer-halls - the money then being used for the development and administration of African facilities, (l) Amongst the inhabitants of Cato Manor and particularly amongst women who traditionally brewed the beer, this caused much dissatisfaction. However, discontent was prevented from reaching breaking -point by the police strategy of ignoring illegal brewing as long as amounts did not exceed more than k to 8 gallons, and also by only carrying out very perfunctory raids. (2) Another dimension was added to the beer-hall issue in the form of complaints by women that this was not the traditional way of doing things. They said that men should obtain beer from their women instead of frequenting the beer halls, and more importantly, by patronising the beer-halls, men were depriving their women of what little money they could have paid them. (3) In this complaint centering around the fact that an element of traditional life was being disrupted, is contained another issue of basic importance to the Natal riots in general. The policies of the government as implemented by the Durban Corporation in the case of Cato Manor meant the fragmentation of a traditional and still important social order. The economic function of the women of Cato Manor, and ass will be seen later, of most Natal women was being removed. In addition to basic deprivation it was this factor that can to a large extent be seen as the reason for the intensity and militancy of the women's attacks on the beer-halls and on Corporation property. Cato Manor was an area unique among the locations and townships of Durban. Its inhabitants had moved there in the years just after the war without any official sanction. Cato Manor was unplanned, and as a result of its spontaneous creation far less controlled and policed than any of the townships set up as a result of government planning. Because of this freedom Cato Manor was a haven for all those who were illegally in the urban areas, or whose livelihood contravened the multitude of rules and regulations governing the lives of Africans. Cato Manor's large population of shebeen queens owed its existence to this lack of control. (4) In 1958 there had been considerable discontent and unrest in Cato Manor over the attempt to implement shack-removal schemes, thereby clearing the slum and transferring much of its population to the new township of Kwa Mashu. At Kwa Mashu where rents were higher and which was also less centrally situated than Cato Manor, there was far more rigid control. Removals would have in effect meant that. Cato Manor's large illegal population, including the shebeen Queens and petty traders, would have been deprived of their livelihoods or endorsed out of the urban areas. (5) It was in this context that threats of a Typhoid epidemic in June 1959 caused the Durban Corporation to decide to radically increase and improve sanitation measures in Cato Manor, and to eliminate any conditions conducive to the breeding of flies. The refusal of the inhabitants of Cato Manor to do away with the large quantities of illegal liquor negated the health measures taken by the authorities. Finally, municipal labourers were ordered to enter Cato Manor and destroy all stills. The resentment aroused by this action caused a large group of women to march on the Booth Road Beerhall on June 17th whereupon they chased out the male customers and destroyed the beer. (6) The rioting spread rapidly to other Durban beerhalls and a large proportion of the Corporations property was destroyed. In addition, a successful beer boycott was launched. In Cato Manor violence had subsided by the beginning of July at which time it had already spread to such areas as Verulam and Umbumbulu. Six weeks after the initial rioting essential services had not yet been restored fully in Cato Manor. By the beginning of August unrest was rife in many of Natal's smaller towns as well as a large section of the rural areas.

- Description: Knowledge of the factors that drive species distributions provides a fundamental baseline for several areas of research including biogeography, phylogeography and biodiversity conservation. Data from 148 minimally disturbed sites across a large drainage system in the Cape Floristic Region of South Africa were used to test the hypothesis that stream fishes have similar responses to environmental determinants of species distribution. Two complementary statistical approaches, boosted regression trees and hierarchical partitioning, were used to model the responses of four fish species to 11 environmental predictors, and to quantify the independent explanatory power of each predictor.

- Description: In observing and plotting the dialectics of how our present world works, fragmenting as it integrates we struggle in wanting to pin down a moving target! Unlike the world of science with its physical laws, the social nature of the world and its relations across borders keep changing course with social and transnational relations constantly mutating. This makes it rather difficult to plot the complexity of human relations, also those across borders. As the late Nobel Laureate Herbert Simon once said, the social sciences are, after all, the really ‘hard’ sciences. They are so hard because they are so hard to explain.

- Description: This essay traces a critical genealogy of counter-memory – spanning critical theory, film and contemporary art – bound to what Rosi Braidotti terms nomadic subjectivity. Engaging with the work of feminist and postcolonial theorists and artists, this essay charts the import of nomadic subjectivity as a method for staying with the many times and histories of global contemporaneity. It aims to move beyond thinking of counter-memory as simply a means to maintain or register erased and/or contested histories, or as a dialectical mnemonic system. It charts an alternative concept of counter-memory, one that is post-dialectical, not bound to the formulas of either/or, us/them or self/other, but which is instead committed to the endless accumulation and proximities of things – the and–and.

- 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: Governments can intervene to a greater or lesser extent in managing the risks that citizens face. They can adopt a maximal intervention approach (e .g. COVID‐19) or a hands‐off approach (e .g ., unemployment) , effectively “responsibilizing” their citizens. To manage the cyber risk, governments publish cyber‐related policies. This article examines the intervention stances the governments adopt in supporting individual citizens managing their personal cyber risk. The authors pinpoint the cyber‐related responsibilities that several governments espouse, applying a “responsibilization” analysis. Those applying to citizens are identified, thereby revealing the governments' cyber‐related intervention stance. The analysis reveals that most governments adopt a minimal cyber‐related intervention stance in supporting their citizens. Given the increasing number of successful cyber attacks on individuals, it seems time for the consequences of this stance to be acknowledged and reconsidered. The authors argue that governments should support individual citizens more effectively in dealing with cyber threats.

- Description: Naphthoquinones have been found to have a wide range of biological activities, including cytotoxicity to cancer cells. The secondary metabolites lapachol, α- and β-lapachone and a series of 25 related synthetic 1,4-naphthoquinones were screened against the oesophageal cancer cell line (WHCO1). Most of the compounds exhibited enhanced cytotoxicity (IC50 1.6–11.7 μM) compared to the current drug of choice cisplatin (IC50 = 16.5 μM).

De La Rey rides (yet) again : Afrikaner identity politics and nostalgia in post-apartheid South Africa

- Description: In 2006 a relatively unknown South African artist with the stage name Bok van Blerk released his debut album called “De la Rey”. The album included a music video of the title track that calls upon the legendary Boer War general to save the volk (people) from the wantonly destructive strategies of the British imperial forces: the scorched earth policy and the subsequent internment of women and children in concentration camps. The British justified such extreme – some would say ‘genocidal’ – strategies so as to prevent non-combatants from supporting the irregular Boer soldiers. Although he did not believe that the war could be won on account of the overwhelming odds that the Boer forces faced, De la Rey still fought to the bitter end. Needless to say, he was on the losing side.

Deconstructing the Transvaal Supergroup, South Africa: implications for Palaeoproterozoic palaeoclimate models

- Description: Current correlations between the Pretoria and Postmasburg Groups of the Transvaal Supergroup are shown to be invalid. The Postmasburg Group is also demonstrated to be broadly conformable with the underlying Ghaap Group and therefore considerably older (~2.4 Ga) than previously supposed. The new stratigraphy documents an extensive (100 Ma) and continuous cold-climate episode with a glacial maximum at the Makganyene Formation diamictite. Iron formations of the underlying Asbesheuwels and Koegas Subgroups and overlying Hotazel Formation have similar origins, related, respectively, to the onset and cessation of the glacial event. This interpretation of the Transvaal Supergroup stratigraphy has significant implications for various Palaeoproterozoic environmental models and for the timing of the development of an oxygenated atmosphere.
