- Description: preprint , Modernism tends to be criticised, internationally, as politically conservative. The objection is often valid, although the charge says little about the quality of artistic achievement involved. This article argues that the alliance between Modernism and political conservatism is by no means a necessary one, and that there are instances where modernist vision has been used to convey substantive political insight, effective social critique and solid resistance. To illustrate the contrast,the article juxtaposes the abstract Modernism associated with Ben Nicholson and World War 2, with a neglected strain of South African railway poetry which uses modernist techniques to effect a powerful critique of South Africa’s apartheid dispensation. The article sustains a distinction between universalising modernist art that requires ethical work from its audiences to achieve artistic completion, and art in which modernist vision performs the requisite ethical work within its own formal constraints. Four very different South African railway poems, by Dennis Brutus, John Hendrickse, Alan Paton, and Leonard Koza, are examined and contextualised to demonstrate ways in which a modernist vision has been used to portray the social disruptions caused by apartheid. Modernist techniques are used to turn railway experience into a metonym for massive social disruption,without betraying the social reality of the transport technology involved.

- Description: At present the Swedish points system is one of the main determinants of an applicant either being granted or refused entry into many South African higher education institutions (HEIs). Using a grounded theory approach, this article interprets the experiences of participants whose school performance and therefore university 'entry points' were lower than the expected norm. Despite not meeting standard university entry requirements, these students succeeded at university, completing their degrees in the minimum time available and going on to higher degrees. The journey of these participants - from low entry points to academic success - suggests that points based on school performance are not necessarily the best way of identifying students' potential to succeed in the contemporary South African educational context. If their entry points were not a good indication of their ability to thrive at university, the article asks, what is it about these participants that accounts for their success? And what implications does this have for South African practice, not only with regard to admissions policies but also in relation to the responsibilities of HEIs to students once they are admitted?

- Description: Online version of original print edition of the Special Publication of the J.L.B. Smith Institute of Ichthyology; No. 9 , Klipfishes of the subfamily Clininae are among the dominant intertidal fishes in southern Africa. Except for a few tropical clinine members such as Clinus xanthosoma Bleeker, Clinus ekloniae McKay and Petraites roseus (Gunther), these diverse temperate forms seem to be replaced by members of the Blenniidae in the intertidal zone of the tropical Indo-Pacific. Klipfishes have not been collected often in the tropical IndoPacific, but often enough to indicate a distribution for C. xanthosoma from Japan through the Philippines to Indonesia and Ceylon. In a recent publication Shen (1971 b) has brought our knowledge of C. xanthosoma up to date and described a new genus, Springeratus to house this species. The status of C. halei has been and still remains uncertain since Day described it in 1888. While collecting fishes at Mauritius, an undescribed intertidal clinid was obtained. This population of live-bearing klipfish contributes to our understanding of the zoogeography and possible relationships of Australian and southern African Clininae. Penrith (1969: r 14) hypothesized sea-weed transport of a clinid ancestor from Australia to South Africa. The Mauritian species favours her hypothesis as well as casting some doubt on the validity of Springeratus as a genus different from Clinus (sensu Penrith, 1969).

Attempts to restrict the concept of Acanthiops to Ac. marlieri (Demoulin) and re-erect Afroptiloides Gillies, syn. n., for Ac. elgonensis Lugo-Ortiz & McCafferty, Ac. griffithsi Lugo-Ortiz & McCafferty, Ac. tsitsa Barber-James & McCafferty, Ac. variegatus (Gillies), Ac. varius (Crass) and Ac. zomba Lugo-Ortiz & McCafferty, are shown to be based on inconsistent and inadequate morphological features that result in a paraphyletic taxonomy. The unofficial separate treatment of Ac. cooperi (Gillies & Wuillot) and Ac. erepens (Gillies) under Platycloeon Gillies & Wuillot is also shown to be paraphyletic. Acanthiops faro Barber-James & McCafferty, sp. n., is described from larvae from Guinea, and is distinguished by the combination of a papillate projection on labial palp segment 2, small tubercles on terga 1-8 and abdominal colour pattern. Acanthiops io Lugo-Ortiz & McCafferty, sp. n., is described from larvae from the Democratic Republic of Congo, and is distinguished by the combination of a papillate projection on palp segment 2, elongate tubercles on terga 1-9 and abdominal colour pattern. The larva of Ac. erepens (Gillies) is redescribed to incorporate morphological features and variability previously not accounted for, and larvae originally assigned to Baetis cataractae Crass are shown to be equivalent to Ac. erepens. New locality data or emendations on locality data are provided for Ac. griffithsi, Ac. tsitsa Barber-James & McCafferty and Ac. varius (Crass).

- Description: This paper attempts to describe the search for the parameter(s) to represent solar wind effects in Global Positioning System total electron content (GPS TEC) modelling using the technique of neural networks (NNs). A study is carried out by including solar wind velocity (Vsw), proton number density (Np) and the Bz component of the interplanetary magnetic field (IMF Bz) obtained from the Advanced Composition Explorer (ACE) satellite as separate inputs to the NN each along with day number of the year (DN), hour (HR), a 4-month running mean of the daily sunspot number (R4) and the running mean of the previous eight 3-hourly magnetic A index values (A8). Hourly GPS TEC values derived from a dual frequency receiver located at Sutherland (32.38° S, 20.81° E), South Africa for 8 years (2000–2007) have been used to train the Elman neural network (ENN) and the result has been used to predict TEC variations for a GPS station located at Cape Town (33.95° S, 18.47° E). Quantitative results indicate that each of the parameters considered may have some degree of influence on GPS TEC at certain periods although a decrease in prediction accuracy is also observed for some parameters for different days and seasons. It is also evident that there is still a difficulty in predicting TEC values during disturbed conditions. The improvements and degradation in prediction accuracies are both close to the benchmark values which lends weight to the belief that diurnal, seasonal, solar and magnetic variabilities may be the major determinants of TEC variability.

- Description: The Third SADTU Congress, held at the World Trade Centre in Kempton Park, was attended by over 800 delegates, representing 100 000 teachers country-wide. Delegates were elected at Branch level, ensuring grass roots participation in the highest decision making body of the Union. The Congress served to confirm SADTU’s position as the largest teacher Union in the country, and demonstrated a strongly unified focus around the theme: “Unionise and Reconstruct for Teacher Empowerment”. The success of any Congress must be measured against the aims it sets itself. Our Congress had two aims: to elect new leadership for the next two years, and to adopt resolutions which would inform the direction and programmes of the Union in this period. While we successfully completed the former task, we could only make a start on the second aspect - confirming the fact that the period we are entering is far more complex than before, and in need of extensive analysis and debate. We therefore mandated the SADTU National Council to formalise the adoption of resolutions arising from the reports. A Special National Council was convened on 25/26 August, with extended participation by regions, and the Congress report can now be finalised.

Colour patterns, number of gill-rakers, body depth, second anal spine length, pectoral-fin length, and caudal peduncle depth are important aids for identification of the Red Sea species. Two synonyms of Apogon guamensis were based on juvenile material: Apogon ocellatus from Madagascar and Apogon spongicolus from the Red Sea. Rüppell’s, Günther’s and Klausewitz’s concepts of Apogon annularis are reviewed. Apogon erdmani is a synonym of Apogon annularis. Apogon savayensis and another wide spread new species were not found in any Red Sea collections we examined.

- Description: Publisher version , Traditional approaches to monitoring aquatic systems are often limited by the need for data collection which often is time-consuming, expensive and non-continuous. The aim of the study was to map the spatio-temporal chlorophyll-a concentration changes in Malilangwe Reservoir, Zimbabwe as an indicator of phytoplankton biomass and trophic state when the reservoir was full (year 2000) and at its lowest capacity (year 2011), using readily available Landsat multispectral images. Medium-spatial resolution (30 m) Landsat multispectral Thematic Mapper TM 5 and ETM+ images for May to December 1999–2000 and 2010–2011 were used to derive chlorophyll-a concentrations. In situ measured chlorophyll-a and total suspended solids (TSS) concentrations for 2011 were employed to validate the Landsat chlorophyll-a and TSS estimates. The study results indicate that Landsat-derived chlorophyll-a and TSS estimates were comparable with field measurements. There was a considerable wet vs. dry season differences in total chlorophyll-a concentration, Secchi disc depth, TSS and turbidity within the reservoir. Using Permutational multivariate analyses of variance (PERMANOVA) analysis, there were significant differences (p < 0.0001) for chlorophyll-a concentration among sites, months and years whereas TSS was significant during the study months (p < 0.05). A strong positive significant correlation among both predicted TSS vs. chlorophyll-a and measured vs. predicted chlorophyll-a and TSS concentrations as well as an inverse relationship between reservoir chlorophyll-a concentrations and water level were found (p < 0.001 in all cases). In conclusion, total chlorophyll-a concentration in Malilangwe Reservoir was successfully derived from Landsat remote sensing data suggesting that the Landsat sensor is suitable for real-time monitoring over relatively short timescales and for small reservoirs. Satellite data can allow for surveying of chlorophyll-a concentration in aquatic ecosystems, thus, providing invaluable data in data scarce (limited on site ground measurements) environments.

- Description: Central to the tumultuous student protests of 2015 and 2016 was an urgent call for the decolonisation of South African universities. Existing curricula, including teaching and assessment practices, as well as institutional cultures and structures were challenged. Against this backdrop, in this article we focus on the academic leadership role of Heads of Departments (HoDs) at Rhodes University. In this small-scale project we interrogate how HoDs conceptualised their roles in this uncertain and complex context. From the data analysis a number of tensions emerged in the ways in which they articulated and enacted their roles. The findings indicate that the protests have contributed to the increasing complexity of the role of an HoD. Issues raised during the protests catalysed HoDs at Rhodes University, some for the first time, into considering the implications of the decolonising call from students and into exercising stronger transformative leadership roles.

One of the key hallmarks of CSCs is the ability to grow anchorage-independently under serum-free culture conditions resulting in the formation of tumourspheres. It has further been reported that these cells are resistant to traditional chemotherapeutic agents.

In one well-studied, classic, flood basalt province, the Mesozoic Karoo province of southern Africa, magmatism occurred in the following tectonic settings: (a) continental rifting leading to ocean-floor spreading in the South Atlantic Ocean (Etendeka suite of Namibia); (b) stretched continental lithosphere and rifting not leading directly to ocean-floor formation (Lebombo suite of southeastern Africa); and (c) an a-tectonic, within-plate, continental setting characterized by an absence of faulting or warping (Lesotho highlands and Karoo dolerites of South Africa).

- Description: Local perceptions of environmental and climate change, as well as associated adaptations made by local populations, are fundamental for designing comprehensive and inclusive mitigation and adaptation plans both locally and nationally. In this paper, we analyze people’s perceptions of environmental and climate-related transformations in communities across the Western Solomon Islands through ethnographic and geospatial methods. Specifically, we documented people’s observed changes over the past decades across various environmental domains, and for each change, we asked respondents to identify the causes, timing, and people’s adaptive responses. We also incorporated this information into a geographical information system database to produce broad-scale base maps of local perceptions of environmental change. Results suggest that people detected changes that tended to be acute (e.g., water clarity, logging intensity, and agricultural diseases). We inferred from these results that most local observations of and adaptations to change were related to parts of environment/ecosystem that are most directly or indirectly related to harvesting strategies. On the other hand, people were less aware of slower insidious/chronic changes identified by scientific studies. For the Solomon Islands and similar contexts in the insular tropics, a broader anticipatory adaptation planning strategy to climate change should include a mix of local scientific studies and local observations of ongoing ecological changes.
