BackgroundMany countries aiming to suppress SARS-CoV-2 recommend the use of face masks by the general public. The social meanings attached to masks may influence their use, but remain underinvestigated.MethodsWe systematically searched eight databases for studies containing qualitative data on public mask use during past epidemics, and used meta-ethnography to explore their social meanings. We compared key concepts within and across studies, then jointly wrote a critical synthesis.ResultsWe found nine studies from China (n=5), Japan (n=1), Mexico (n=1), South Africa (n=1) and the USA (n=1). All studies describing routine mask use during epidemics were from East Asia. Participants identified masks as symbols of solidarity, civic responsibility and an allegiance to science. This effect was amplified by heightened risk perception (eg, during SARS in 2003), and by seeing masks on political leaders and in outdoor public spaces. Masks also acted as containment devices to manage threats to identity at personal and collective levels. In China and Japan, public and corporate campaigns framed routine mask use as individual responsibility for disease prevention in return for state- or corporate-sponsored healthcare access. In most studies, mask use waned as risk perception fell. In contexts where masks were mostly worn by patients with specific diseases (eg, for patients with tuberculosis in South Africa), or when trust in government was low (eg, during H1N1 in Mexico), participants described masks as stigmatising, uncomfortable or oppressive.ConclusionFace masks can take on positive social meanings linked to solidarity and altruism during epidemics. Unfortunately, these positive meanings can fail to take hold when risk perception falls, rules are seen as complex or unfair, and trust in government is low. At such times, ensuring continued use is likely to require additional efforts to promote locally appropriate positive social meanings, simplifying rules for use and ensuring fair enforcement.

Abstract A foliar disease of peanuts, previously unreported in the USA, was found in Texas in 1972. The pathogen was identified as a species of Ascochyta. Further cultural studies have revealed this fungus to be Phoma arachidicola Marasas, Pauer, and Boerema. Pycnidia form profusely at 20 C and 25 C. Pycnidiospores are borne on short pycnidiosphores and are predominantly one-celled in culture. Spores produced in pycnidia on infected leaflets become 1 septate. Large 1-septate spores, as well as an occasional 2-septate spore, may form in culture. Optimum temperature for mycelial growth in 20 C; little or no growth occurs at 5 C or above 30 C. The teleomorphic state develops in the field on fallen leaflets and can be induced to form in the laboratory on sterilized peanut leaflets between 15 and 20 C. Cultures derived from single ascospores form pseudothecia. Pycnidiospores, ascospores, and chlamydospores are all infective units. Because this fungus produces hyaline ascospores and pseudoparaphyses, it has been transferred to the genus Didymella as Didymella arachidicola (Choch.) comb. nov. Comparisons with 15 isolates causing web blotch of peanut in the USA, Argentina, and South Africa indicate that web blotch symptoms are produced by the same fungal species.

The concept of unfair labour practice has been introduced into South Africa through the Labour Relations Act and it is argued that certain psychometric testing practices can be interpreted as falling under the definition of an unfair labour practice. Empirical results are presented indicating that different ethnic groups obtain significantly different mean ability test scores. A case-study is cited to show that this would result in underprediction of performance on a criterion for the lower scoring of two groups if test scores are regarded as comparable. It is argued that any interpretation of psychometric data in South Africa that does not take account of possible differences between ethnic groups is likely to ignore a significant moderator variable, given the history of ethnically based discriminatory practices in this country. Arguments based on meta-analytical research in the USA, to the effect that psychometric ability tests do not discriminate unfairly against disadvantaged groups if the same tests and norms are used, should not be assumed to hold in South Africa. Various conceptions of what constitutes fairness in selection are considered, and it is concluded that there is a need for employers to make explicit in their selection policies the trade-off between economic and social costs of employment practices. Finally, some implications for users of psychometric tests in industry are considered, in order to forewarn of likely developments in this field.

Assessment Activities

The Common Tasks for Assessment (CTA) was a new assessment programme that was introduced in 2002 in South Africa for all Grade 9 learners. The purpose of this paper is to articulate some concerns around the use of contextualised assessment activities in the CTA. The study reported here was carried out in 2003. Data for the study was generated from lesson observations and interviews with the participant teachers and groups of learners. It is argued that although the intentions behind the design of the CTA are well meaning and noble, there are in fact some learners who may be unintentionally disadvantaged by the design of the CTA which uses an extended context as a source for all the assessment tasks. In this paper two unintended consequences of using ‘real life’ contexts are identified and the implications of these are discussed, by linking the observations to research carried out in the UK and the USA.

Almost exactly twenty years ago, the first of a series of conferences dedicated to cosmic masers took place in Arlington, Virginia in the USA (March 9–11, 1992). Two more followed, each on a different continent, in Mangaratiba, near Rio de Janeiro, Brasil (March 5–10, 2001) and in Alice Springs, Australia (March 12–16, 2007). As at all others, a large part of the international maser community convened from January 29 to February 3, 2012 in splendid Stellenbosch, South Africa, to discuss the state of the art of the field.

This article investigates the competitiveness of the South African wheat industry and compares it to its major trade partners. Since 1997, the wheat-to-bread value chain has been characterised by concentration of ownership and regulation. This led to concerns that the local wheat market is losing international competitiveness. The competitive status of the wheat industry, and its sub-sectors, is determined through the estimation of the relative trade advantage (RTA). The results revealed declining competitiveness of local wheat producers. Compared to the major global wheat producers, such as Argentina, Australia, Brazil, Canada, Germany and the USA, South Africa’s unprocessed wheat industry is uncompetitive. At the same time, South Africa has a competitive advantage in semi-processed wheat, especially wheat flour. The institutional environment enables the importation of raw wheat at lower prices and exports processed wheat flour competitively to the rest of Africa.

Lewis Nkosi is increasingly recognized as one of South Africa’s foremost literary critics, and also as an iconoclastic writer of novels and plays. His years as an exile during the apartheid era meant, however, that his reputation within South Africa was for some time less secure than it was abroad. Born in Chesterville, a black Durban township, Nkosi came from a female-headed, working-class family. He was mission-schooled in Eshowe and then embarked on a career that began with a short but important journalistic stint at Drum magazine. To take up a Nieman Fellowship at Harvard in 1961, Nkosi left South Africa on a one-way exit permit. For the rest of his life he lived variously in England, Zambia, Poland, the USA and Switzerland, following a writing and academic career. Nkosi’s style is a distinctive one, at odds with much of the naturalist writing that characterized South African black ‘protest’ fiction of the apartheid years. Influenced by the writings of Faulkner, Kafka and Joyce, Nkosi’s style is modernist, suggestive and symbolic. His loyalty to form, and to the stringent demands of a modernist perception of art, is evident in his critical essays, gathered into three collections: Home and Exile (1965), The Transplanted Heart: essays on South Africa (1975), and Tasks and Masks: themes and styles of African literature (1981).
