- Description: This paper discusses the intellectualisation of African languages from a historical perspective. It explores how different historical epochs ascribed certain values on African languages, thereby facilitating or impeding the development of the languages, which remain in urgent need of transformation into fully functional languages in modern society. Such an exploration is not undertaken for the purposes of generating another historical account or rivalling others already in place, but in order to contribute towards understanding the integral role of African languages in the broader decolonisation and transformation endeavours across the continent.

- Description: The objectives were to design a simple, illustrated patient information leaflet for the antiretroviral regimen of stavudine, lamivudine and efavirenz and to evaluate its readability and acceptability in the local Xhosa population. In order to achieve this, a further objective was to design and evaluate illustrations to include in the patient information leaflet which were culturally acceptable and well interpreted. Illustrations or pictograms were designed to illustrate selected instructions appearing in the patient information leaflet and were individually tested in 30 Xhosa participants who had a maximum of 8 years of formal schooling. Results were used to improve the pictograms for inclusion in the patient information leaflet. The patient information leaflet was designed and tested in sixty Xhosa participants with varied levels of education who had stated they could read. Demographic data were collected and they were then asked to read the patient information leaflet, available in both English and isiXhosa, and a series of questions was asked to assess its comprehension and acceptability. The overall average rate of understanding was 95. Six of the 20 questions were located and understood by all participants, and only two questions resulted in less than an 85 correct response. Physical appearance and quantity of information were highly rated and all participants were enthusiastic about the inclusion of pictograms.

- Description: Language policies in sub-Saharan African nations emerge out of specific political, historical, socioeconomic, and linguistic conditions. Education plays a crucial role for all spheres of language policy. Policies either upgrade or downgrade indigenous languages through their application at various educational institutions. The most significant example is the selection of the language (s) used as languages of learning and teaching at higher-education institutions. The region’s colonial history also influences the language policies of the independent African states. Language policy in Senegal is an example of a francophone country focusing on a linguistic assimilation policy in which minor reforms in favor of indigenous languages have taken place.

- Description: Prof Duncan has outlined the relative merits and demerits of self-regulation, co-regulation and deregulation, with which we are in broad agreement. She has also ably dealt with the three functions of regulatory bodies, namely the setting of ground rules for the industry to ensure best practice; enforcement of these; and adjudication of claims and counter claims re journalistic practice (Duncan 2012, p17). Finally, she has also taken up the issue of the necessity of accepting Third Party Complaints as one of the fundamental mechanisms by which citizens can make complaints on the basis of principle, rather than being personally aggrieved. While we are in broad agreement with her on these issues, we would like to highlight some further points for consideration.

- Description: The name Phoberus capensis (Scholtz) is applied to a small flightless, keratinophagous beetle endemic to the Cape Floristic Region of South Africa. Its gross distribution stretches from roughly 1000 km from the Cederberg (32°24’22” S, 19°04’50” E) to Grahamstown (33°20’07” S, 26°32’50” E). The populations are spatially discrete, restricted to relict forests of the southern Cape and disjunct high montane refugia of the Cape Fold Mountains. We test the hypothesis that there is more than one distinct species nested within the name P . capensis . Phylogenetic relationships among populations were inferred using molecular sequence data. The results support three distinct evolutionary lineages, which were also supported by morphological characters. Divergence time estimates suggest Pliocene-Pleistocene diversification. Based on these results, it is suggested that the P. capensis lineage experienced climatically-driven allopatric speciation with sheltered Afrotemperate forests and high mountain peaks serving as important refugia in response to climatic ameliorations. The P. capensis complex thus represents a speciation process in which flight-restricted populations evolved in close allopatry, possibly as recently as the Pleistocene. Two divergent and geographically distinct lineages are described as novel species: The new species, P . disjunctus sp. n. and P . herminae sp. n., are illustrated by photographs of habitus and male aedeagi.

- Description: Extant genera and subgenera of the Trogidae (Coleoptera: Scarabaeoidea) are reviewed. Contemporary classifications of this family have been based exclusively on morphological characters. The first molecular phylogeny for the family recently provided strong support for the relationships between morphologically defined genera and subgenera. On the basis of morphological, molecular and biogeographical evidence, certain taxonomic changes to the genus-level classification of the family are now proposed. The family is confirmed as consisting of two subfamilies, Omorginae Nikolajev and Troginae MacLeay, the former with two genera, Omorgus Erichson and Polynoncus Burmeister, and the latter with two genera, Trox Fabricius and Phoberus MacLeay stat. rev. Phoberus is restored to generic rank to include all Afrotropical (including Madagascan endemic) species; Afromorgus is confirmed at subgeneric rank within the genus Omorgus ; and the monotypic Madagascan genus Madagatrox syn. n. is synonymised with Phoberus. The current synonymies of Pseudotrox Robinson (with Trox ), Chesas Burmeister, Lagopelus Burmeister and Megalotrox Preudhomme de Borre (all with Omorgus ) are all accepted to avoid creating speculative synonyms before definitive phylogenetic evidence is available.

- Description: The cicadas are a group of insects belonging to the order Hemiptera which comprises a diverse range of insects including the bugs, leafhoppers, aphids, scale insects etc. The Hemiptera are characterised by specialised mouth parts that are adapted for piercing and sucking up sap from host plants or animal juices from their prey. All cicadas are plant feeders and can be extremely camouflaged when sitting and feeding on a branch, although the males give themselves away by their persistent, often high pitched calls.

- Description: Smith's (personal communication) work in a continuous, commercial cabbage-growing area near Grahamstown showed that parasitism of diamondback moth averaged over 60% and could reach 100%. In many parts of the world cabbage crops are not under continuous cultivation, and periodic cropping Systems may demonstrate différent patterns of parasitism, especially in disrupted, patchy subsistence crops. Cabbage (Brassica oleracea) is the most commonly grown cruciferous crop in subsistence gardens in the suburbs of Grahamstown East. The subsistence farmers' crops are considered patchy because the cabbages are grown in small and relatively widely separated plots. Thèse gardens provided an opportunity to follow Talekar and Shelton's (1993) suggestion to investigate the population dynamics of P. xylostella (a useful model pest) and its rate of parasitism on cabbages of subsistence farmers where commercial pesticides are used less.

Cabbage (Brassica oleracea) is the most commonly grown cruciferous crop in subsistence gardens in the suburbs of Grahamstown East. The subsistence farmers' crops are considered patchy because the cabbages are grown in small and relatively widely separated plots. Thèse gardens provided an opportunity to follow Talekar and Shelton's (1993) suggestion to investigate the population dynamics of P. xylostella (a useful model pest) and its rate of parasitism on cabbages of subsistence farmers where commercial pesticides are used less.

- Description: Seasonal fluctuations of diamondback moth and its hymenopteran parasitoids were recorded weekly from April 1997 to November 1999 at four cabbage sites in the Grahamstown area of the Eastern Cape, South Africa. Two sites were commercial farms with active spraying programmes; the others were unsprayed. Infestation levels were highest during spring (September to November) and autumn (March to May), where 100% infestation of plants was reached at times. The highest infestation was found during the spring months, where 12 larvae/plant were found at the unsprayed sites and between 6 and 10 larvae at the sprayed sites. At the unsprayed sites abundance of diamondback moth larvae and parasitoids was high during 1997, but much lower during 1998 and 1999, indicating possible control by the parasitoids. Nine species of parasitoid were recorded from diamondback moth during this period and four (Cotesia plutellae (Kurdjumov) (Hymenoptera: Braconidae), Diadegma mollipla (Holmgren) (Hymenoptera: Ichneumonidae), Diadromus collaris Gravenhorst (Hymenoptera: Ichneumonidae) and Oomyzus sokolowskii (Kurdjumov) (Hymenoptera: Eulophidae)) showed potential as biological control agents. The highest rate of parasitism was found from mid-autumn to the beginning of winter (April to June) and from mid-spring to the beginning of summer (October to December). Percent parasitism varied throughout the year, ranging between 10% and 80%. Parasitism of 100% was observed when moth numbers were low. Different species of parasitoids were found to be dominant at different times of the year.

- Description: Many of the theoretical and methodological frameworks that are currently influential in Environment and Sustainability Education (ESE) research in South Africa foreground interventionist research, activism, causal explanation, critique, social-ecological transformation and decoloniality. These frameworks guide ESE researchers to design, implement and report on research in particular ways, hence influencing how social-ecological phenomena, learning and social change are understood and enacted. In this essay, I present some exploratory perspectives on the relevance and potential contribution of phenomenological approaches to ESE research, especially Goethean inspired observation.

- Description: As a contribution to discussions about how ESE research respond to increasing urgency and climate emergencies, this essay discusses the relation between education and the pursuit of societal transformation with a view to questions of socio-ecological justice. Our research interest centers on young children’s participation and voice, on the inequalities which constitute barriers to this participation, and on the potentials of a more fine-tuned pedagogy which listens to children’s voices and their relations with the non-human environment in our research practices. This listening is a radical process of unlearning and rethinking ‘urgency’. The essay is based on an ongoing dialogue about how research on sustainability education might respond to the voices of children in marginalized positions across two very different geographical and socio-cultural settings–the Danish welfare state and post-apartheid South Africa (see James and Jørgensen, forthcoming). Here we draw attention to the dangers of assumptions underlying urgency (dualism and instrumentalism) and the voices of young children in research as a practice that resists these dangers.

- Description: An Identity Document (ID) is needed by South Africans to study, apply for a pension or get married. However, Home Affairs, the state department responsible for issuing them, is poorly managed. The popular Daily Sun tabloid newspaper mediates for its five million working class readers the frustration caused by this incompetency in its “Horror Affairs” column. Readers tell their stories about (not) getting their IDs, stories often of suicide, depression and “giving up” on life. Using a Lacanian frame, and through a close reading of “Horror Affairs” texts, I argue that this tabloid plays a therapeutic role for its socially marginalised readers by mediating the “invisibility” engendered by the modernising state and its administrative technologies. Given the concern about high rates of mental health illness in South Africa, the research also demonstrates how popular culture forms can alert health care practitioners to issues which may otherwise go unnoticed.

- Description: Literature exists that studies media coverage of natural disasters. The media has the potential to influence how governments react to disasters, how emergency services handle disasters, and how people receive and react to the news of disasters. However, the media sometimes sensationalizes the news about the disasters and focus on other manifestations such as panic, looting, shock, emerging heroes and villains, human conflict, and suffering. This study aims to analyze the media coverage of the 2022 floods in the province of KwaZulu-Natal (KZN) in South Africa. In particular, the study seeks to evaluate if there was media coverage of the floods and what the contents of the coverage were. The study used content analysis to examine the presence of KZN floods from three selected online newspapers, focusing on whether the floods were covered, and which issues or themes dominated the reporting of the floods. The aim here was to examine the role that the media played during this disaster in South Africa. Content analysis was used to note the number of stories covered during the KZN floods in the media, the key themes that dominated the coverage of the floods and factors that influenced the media coverage of the floods. The selected online newspapers are News24, Independent Online (IOL) and TimesLive. These newspapers were purposively selected because of their wider national readership, the ideology of the newspaper, strong online presence, and type/style of reporting. Based on the above-presented data, we argue that there was sufficient coverage of the KZN floods in South African media. The study also discovered that the following issues or stories dominated the reporting/coverage of floods: disaster management, casualties, relief measures, the role of the government, business interests, the role of opposition parties, destruction of infrastructure, and effects on social life.

- Description: Although two-thirds of countries in the world no longer outlaw lesbian, gay, bisexual, transgender and intersex (LGBTI) relationships, same-sex relationships are still illegal in 76 countries. In the recent past, new laws have been passed in Russia, India, Nigeria, Burundi, Cameroon and Uganda and are being contemplated in other countries to further prohibit same-sex relationships or the so-called ‘promotion of homosexuality’. There is evidence that such new laws precipitate negative consequences not just for LGBTI persons and communities, but also for societies as a whole, including the rapid reversal of key public health gains, particularly in terms of HIV and AIDS and other sexual health programmes, increases in levels of social violence, some evidence of reduced economic growth, and the diversion of attention from sexual and other violence against women and children.

- Description: Abiotic stress tolerance in plants is gaining importance day by day. Different techniques are being employed to develop salt tolerant plants that directly or indirectly combat global food problems. Advanced comprehension of stress signal perception and transduction of associated molecular networks is now possible with the development in functional genomics and high throughput sequencing. In plant stress tolerance various genes, proteins, transcription factors, DNA histone-modifying enzymes, and several metabolites are playing very important role in stress tolerance. Determination of genomes of Arabidopsis, Oryza sativa spp. japonica cv. Nipponbare and integration of omics approach has augmented our knowledge pertaining to salt tolerance mechanisms of plants in natural environments. Application of transcriptomics, metabolomics, bioinformatics, and high-through-put DNA sequencing has enabled active analyses of regulatory networks that control abiotic stress responses. To unravel and exploit the function of genes is a major challenge of the post genomic era. This chapter therefore reviews the effect of salt stress on plants and the mechanism of salinity tolerance along with contributory roles of QTL, microRNA, microarray and proteomics.
