Description: Online version of original print edition of the Special Publication of the J.L.B. Smith Institute of Ichthyology; No. 38 , Recent collecting in the Malawi lakes Chilwa and Chiuta has revealed a new haplochromine cichlid fish, Astatotilapia tweddlei, which is described and illustrated. It is distinguished from most members of this genus by an elongate, rounded caudal fin. Although having a distinctly different colour pattern and more slender pharyngeal bone, it shows a greater similarity to A. paludinosa, known only from the Malagarasi Swamp 1200 km to the north in the Zaire ichthyofaunal province, than it does to members of this genus from the closely adjacent Zambezi province from which this wetland system, in the East Coast province is separated by only some 50 km.

Description: The idea to restructure the union is not a new one. Political changes in our country compelled almost all the unions to consider the possibilities of restructuring the union and the industry in general. New approaches to Collective Bargaining Strategies came to the fore. The good example of these Bargaining strategies was the NUMSA THREE YEAR BARGAINING STRATEGY (1993). Later in the same year, CWIU also introduced its Bargaining Strategy in the form of five pillars. The common thing about Numsa and CWIU bargaining strategies is that they both failed to deliver and the process of setting up working groups are more complex than expected. The main cause of the tap problem in my view is that the existing union structures are a big deterent to the development and implementation of new bargaining strategies. Our Centralised Bargaining victory and the new LRA will demand major union restructuring if we want to utilise the openings created by these new developments. In this discussion paper, I will focus on how we should restructure our union. In this paper, I am suggesting that the union (CWIU) must be made up of four semi-autonomous departments.

Description: Retraction Watch maintains a "running list" of retracted papers on Covid-19 related research. By the end of September 2020, thirty-three retracted Covid-19 papers were listed. We analysed these retracted papers, focusing specifically on how they have been cited by review papers, and subsequently how they have penetrated and potentially distorted public discourse and legitimate research on Covid-19. The study demonstrates the need for more in-depth studies that focus on the phenomenon of citation pollution. We show that the "Covid-19 publication race", amplified by a pressure-to-publish research culture, distorted published science on Covid-19. We highlight the urgency to engage popular media and critical decision makers on how to distinguish between questionable and legitimate science. We also emphasise the importance of dealing with illegitimate research in a timely manner, both from a scholarly communications and research quality perspective. , Retraction Watch maintient une "liste courante" des articles rétractés sur les recherches liées au Covid-19. Fin septembre 2020, trente-trois articles rétractés sur le Covid-19 étaient répertoriés. Nous avons analysé ces articles rétractés, en nous concentrant spécifiquement sur la façon dont ils ont été cités par d'autres articles, et ensuite sur la façon dont ils ont pénétré et potentiellement faussé le discours public et la recherche légitime sur le Covid-19. L'étude démontre le besoin d'études plus approfondies qui se concentrent sur le phénomène de la pollution des citations. Nous montrons que la "course à la publication sur le Covid-19", amplifiée par une culture de la pression à la publication de la recherche, a déformé l'information scientifique publiée sur le Covid-19. Nous soulignons l'urgence d'engager les médias populaires et les décideurs critiques sur la manière de distinguer la science douteuse de la science légitime. Nous soulignons également l'importance de traiter rapidement les recherches illégitimes, tant du point de vue de la communication scientifique que de la qualité de la recherche. , Retraction Watch houdt een "lopende lijst" bij van ingetrokken papieren over Covid-19-gerelateerd onderzoek. Eind september 2020 waren drieëndertig ingetrokken Covid-19 papieren op de lijst geplaatst. We hebben deze ingetrokken papieren geanalyseerd, waarbij we ons specifiek hebben gericht op de manier waarop ze zijn geciteerd door review papers, en vervolgens op de manier waarop ze zijn doorgedrongen en mogelijk vervormd in het publieke discours en het legitieme onderzoek naar Covid-19. De studie toont aan dat er behoefte is aan meer diepgaande studies die zich richten op het fenomeen van de citatievervuiling. We tonen aan dat de "Covid-19-publicatierace", versterkt door een druk om te publiceren onderzoekscultuur, de gepubliceerde wetenschap over Covid-19 vertekend heeft. We benadrukken de urgentie om de populaire media en kritische besluitvormers te betrekken bij het maken van een onderscheid tussen twijfelachtige en legitieme wetenschap. We benadrukken ook het belang van het tijdig aanpakken van onrechtmatig onderzoek, zowel vanuit het oogpunt van wetenschappelijke communicatie als vanuit het oogpunt van de kwaliteit van het onderzoek.

Description: A total of 141 Polydactylus quadrifilis were sampled from the Kwanza Estuary in Angola ranging in size from 436 to 1360 mm fork-length (FL). Of these, 124 were male, six intersex and 11 female. Female fish were significantly longer (mm, FL) and heavier (kg) than males and had significantly higher gonadosomatic indices (GSI’s) than those of males and intersex fish. Transitional (intersex) gonads were delimited, with testicular and ovarian regions separated by connective tissue. The first signs of ovarian tissue appeared on the outer ventral surface of the gonad. A second layer of ovarian tissue was first noticeable at either end of the initial ovarian region and developed back towards the centre of the ventral wall to form a luminal space. Early-stage oocytes were commonly found in the outer area of male regions and residual late-stage spermatids and spermatozoa were found in the luminal space of ovarian regions, suggesting a process of sex change from the outside inwards. A loss of male function was noted with increased ovarian prevalence. Based on this evidence it is suggested that P. quadrifilis in the Kwanza Estuary are protandrous. Owing to the reliance of P. quadrifilis on large highly fecund females for egg production, it is likely that they will be sensitive to fishing practices that target larger individuals within the population.

On location: Narratives of the South African city of the late 1940s and 1950s in film and literature

Description: This article is about narratives, about the forms and meanings constructed by South African storytellers, especially writers and filmmakers. It examines the relationships between examples of these two different narrative forms of literature (fiction and non-fiction) and feature film. Following Turner, the point of departure is that the study of narrative has the potential to provide a framework within which such a two pronged approach can be undertaken. This is not to say that the production of meaning takes place within an exclusive literary or cinematic context. Rather, this approach will allow us to obtain a fuller picture of the narrative of the South African city than is possible by concentrating on one medium. It is based on the premise that narratives are ultimately produced by culture; thus these cultural constructions generate meanings, take on a significance, and assume forms that are articufations of the values, beliefs -the ideology - of the culture.' Literature and film offer specific forms for such narratives. By adopting an interdisciplinary approach which borrows insights from literary and film studies, this article attempts to make a contribution to the fledgling field of South African cultural studies.

Description: Coral reefs are subjected globally to a variety of natural and anthropogenic stressors that often act synergistically. Today, reversing ongoing and future coral reef degradation presents significant challenges and countering this negative trend will take considerable efforts and investments. Scientific knowledge can inform and guide the requisite decision-making process and offer practical solutions to the problem of protection as the effects of climate change exacerbate. However, implementation of solutions presently lags far behind the pace required to reverse global declines, and there is a need for an urgent and significant step-up in the extent and range of strategies being implemented. In this paper, we consider scientific frontiers in natural and social science research that can help build stronger support for reef management and improve the efficacy of interventions. We cover various areas including: (1) enhancing the case for reef conservation and management, (2) dealing with local stressors on reefs, (3) addressing global climate change impacts, (4) and reviewing various approaches to the governance of coral reefs. In sum, we consider scientific frontiers in natural and social science that will require further attention in coming years as managers work toward building stronger support for reef management and improve the efficacy of local interventions.

Description: Private land conservation areas (PLCAs) have become critical for achieving global conservation goals, but we lack understanding of how and when these areas respond to global pressures and opportunities. In southern Africa, where many PLCAs rely on trophy hunting as an income‐generating strategy, a potential ban on trophy hunting locally or abroad holds unknown consequences for the future conservation of these lands. In this study, we investigate the consequences of a potential trophy hunting ban in PLCAs in two biodiversity hotspots in South Africa's Eastern and Western Cape provinces. We used semistructured interviews with PLCA managers and owners to elicit perceived impacts of an internationally imposed trophy hunting ban on conservation activities in PLCAs, and to probe alternative viable land uses.

Description: Doreen Baingana’s Tropical Fish explores the migratory experiences of the main narrator-focalizer, Christine Mugisha, as she travels from Uganda to the United States of America. Although the analyses of home, exile, and migration by writers like Edward Said and Paul Tiyambe Zeleza tend to be ungendered; Baingana seems to elaborate on these concerns by reflecting on the gendered experience of travel. As Carole Boyce Davies has argued, the act of travelling and migration opens up new spaces and possibilities for black women writers as they come into contact with multiple places and cultures. In their encounters with migration, black women are able to negotiate and re-negotiate their identities. This article focuses on how Tropical Fish, interrogates complex, contradictory, ambiguous and often conflicted questions of home and migration with their concomitant issues of belonging and alienation/ estrangement and how they are intimately tied to the maternal bond.

Description: In reviewing the 1990 financial year for TGWU (1 Jan 1990 - 31 Dec 1990) it is clear that the union was in an unstable financial position. The income from subscriptions was forever fluctuating. In most cases expenditure for this period exceeded the income from subscriptions. Our bank balance was, from time to time, in an overdraft situation. The union couldn’t be self-sufficient—and as a result, relied on foreign funding. This report will deal with both the income and expenditure for the said financial period.

Description: The year 1999 is the year of assessing performance and delivery. In the political arena we are reflecting on the accomplishments and shortcomings of our young democracy as we prepare our nation for South Africa's second democratic elections on the 2nd of June 1999. At this time, it is important that we also evaluate the progress we as a united labour movement made subsequent to April 1994, since the involvement of COSATU in our struggle for democracy was and still remains crucial. For women the 2nd of June 1999 presents itself as a challenge, especially women within COSATU. The challenge lies in the need to ensure that women are more represented in all structures of the federation, affiliates, down to local structures. Women make up the majority of citizens in South Africa and have been and remain under represented within the trade union movement. This has been the case since the launch of COSATU in 1985.

Description: The importance of non-timber forest products (NTFPs) to rural livelihoods is widely acknowledged globally, as is the income generated from casual or fulltime trade on village and urban markets. However, there is less understanding of how the condition or status of the neighboring landscapes influence the use of and trade in NTFPs. Here we report on the use and trade in NTFPs in four villages situated along a gradient of decreasing forest cover in southwest Malawi using a mixed-methods approach. Data were sourced via a survey of 286 households, value chain analysis of the four most commonly traded NTFPs (thatch grass, edible orchids, mushrooms, and wild fruits), key informant interviews with NTFP traders and direct observations.

Description: Community-based approaches are pursued in recognition of the need for place-based responses to environmental change that integrate local understandings of risk and vulnerability. Yet the potential for fair adaptation is intimately linked to how variations in perceptions of environmental change and risk are treated. There is, however, little empirical evidence of the extent and nature of variations in risk perception in and between multiple community settings. Here, we rely on data from 231 semi-structured interviews conducted in nine communities in Western Province, Solomon Islands, to statistically model different perceptions of risk and change within and between communities.
