- Description: Bollywood’s popularity as a global cultural form has occurred at the same time as the valorization of difference in the South African political landscape. As the youngest members of the 19th-century labour diaspora, South African Indian youths are the inheritors of a conservative—yet adaptable—home culture amidst the marginalized identities of (post-)apartheid South Africa. Their desire to create an identity for themselves that encompasses their self-perception both as modern South African subjects and as guardians of their traditional home cultures is achieved through Bollywood, which speaks to its diasporic audiences through images of an idealized traditional yet modern India. While India is not a place of return for these youth, their reactivation of a diasporic identity through Bollywood’s representations of a successful Indian diasporic culture and their participation in South African Bollywood concerts and award ceremonies has provided an opportunity for young South African Indians to reimagine their diasporic Indian identity in ways that (re-)connect them to India and to an imagined global diaspora.

- Description: The purpose of this qualitative case study involving six secondary school teachers was to obtain insight into how geometry is taught in selected Nigerian and South African high schools. It also aimed, by making use of the van Hiele model of geometry instruction, to elucidate what possible learning opportunities observed instructional methods could offer learners in the subject. The sample comprised three mathematics teachers from Nigeria and three mathematics teachers from South Africa, all of whom were selected using purposive sampling techniques. Instructional activities in six geometry classrooms were recorded on videotape. The van Hiele learning phases provided the framework for data analysis. The findings of this study indicate that observed teaching methods in geometry classrooms in the participating schools offer learners scant opportunity to learn geometry.

- Description: In aquatic ecosystems, impacts by invasive introduced fish can be likened to press disturbances that persistently influence communities. This study examined invasion disturbances by determining the relationship between non-native sharptooth catfish Clarias gariepinus and aquatic macroinvertebrates in the Eastern Cape, South Africa. A Multiple Before–After Control–Impact (MBACI) experimental design was used to examine macroinvertebrate communities within two rivers: one with catfish and another one without catfish. Within the invaded river, macroinvertebrates showed little response to catfish presence, whereas predator exclusion appeared to benefit community structure. This suggests that the macroinvertebrate community within the invaded river was adapted to predation impact because of the dominance of resilient taxa, such as Hirudinea, Oligochaeta and Chironomidae that were abundant in the Impact treatment relative to the Control treatment. High macroinvertebrate diversity and richness that was observed in the Control treatment, which excluded the predator, relative to the Impact treatment suggests predator avoidance behaviour within the invaded river. By comparison, within the uninvaded river, catfish introduction into the Impact treatment plots indicated negative effects on macroinvertebrate community that was reflected by decrease in diversity, richness and biomass. A community level impact was also reflected in the multivariate analysis that indicated more variation in macroinvertebrate composition within the Impact treatment relative to the Control in the uninvaded river. Catfish impact within the uninvaded river suggests the dominance of vulnerable taxa, such as odonates that were less abundant in the Impact treatment plots after catfish introduction. From a disturbance perspective, this study revealed different macroinvertebrate responses to catfish impact, and suggests that within invaded habitats, macroinvertebrates were less responsive to catfish presence, whereas catfish introduction within uninvaded habitats demonstrated invasion impact that was shown by a decrease in the abundance of vulnerable taxa. The occurrence of non-native sharptooth catfish within many Eastern Cape rivers is a concern because of its predation impact and potential to influence trophic interrelationships, and efforts should be taken to protect uninvaded rivers, and, where possible, eradicate the invader.

- Description: This study examined temporal variation in population dynamics and size structuring of two cyprinid minnows, Pseudobarbus afer and Barbus anoplus, in relation to their proximate physical habitats. Population estimates were determined using three-pass depletion sampling during both summer and winter. The habitats were characterised by seasonal variation in all physico-chemical conditions and spatial variation in substrata compositions. Whereas significant differences in population size were noted between seasons for B. anoplus, no differences were found between seasons for density and capture probability for either species. An increase in boulders was associated with increase in population size and density for P. afer; for B. anoplus, increased percentages of bedrock and bank vegetation were associated with an increase in population size and probability of capture, respectively. According to Canonical Correspondence Analysis, size structuring in P. afer was explained predominantly by seasonality, with smaller length classes associated with the seasonal variable of summer, while larger length classes were associated with pH that was higher in winter. By comparison, for B. anoplus, the habitat variables – bank vegetation and bedrock – accounted for much of the explained variance for size structuring. Recruitment appeared to be the major driver of size structuring for the two species; refugia, especially boulders and bank vegetation, also appeared to be important. Overall, the two species were adapted to the headwater streams that were generally variable in environmental conditions. Potential invasions by non-native invasive fishes that occur within the mainstream habitats threaten these two species. Efforts should continue to protect these minnows from such invasions by constructing barriers to upstream migration of non-native fishes into these headwater habitats.

One has always associated the ability to make mathematical connections, together with the teacher's role in teaching them, with deep mathematical understanding. This article examines the nature and quality of the mathematical connections that the teachers' representations of those connections enabled or constrained. The researchers made video recordings of four Grade 11 teachers as they taught a series of five lessons on algebra-related topics. The results showed that the teachers' representations of mathematical connections were either faulty or superficial in most cases. It compromised the learners' opportunities for making meaningful mathematical connections. The researchers concluded by suggesting that helping teachers to build their representation repertoires could increase the effectiveness of their instructional practices.

This was the first national strike on 2010 World Cup sites by South African construction workers and was therefore an historic event. A second key feature of the strike was the unity displayed by workers and trade unions within a sector organised by several trade unions. Engineering and building workers came out on strike, with the Building Construction & Allied Workers Union (BCAWU) and the National Union of Mineworkers (NUM) standing together as their representative organisations. A third feature of the strike was the widespread sympathy for it by the South African public and media. This was despite it potentially setting back progress with World Cup projects. Fourthly, the pressure placed upon the trade unions' negotiating team by the Ministry of Labour and the FIFA Local Organising Committee (LOC) proved lethal in undermining their, assisting in causing them to dilute their trade union demands and demobilising the national strike.

This study shows that these two words are in fact narratives which reveal the tension, inherent in all historical narratives, between that which is denotative or factual and that which is connotative or fictional. Similarly, the words also form the shifting horizon from which we may see history as a narrative of the past that is always also a narrative of the present. The link between these words will ultimately show the complex, compromised role of the narrator and, perhaps, of all historians.

'Iron on iron': modernism engaging apartheid in some South African railway poems

- 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.

In addition to translocations within its southerly range (Cambray 2003), Cambray (2005) noted that as a result of poor aquaculture practices and introductions from a number of unknown sources, C. gariepinus has now invaded South America, Europe, Asia, and Australia. Its life history characteristics include a fast growth rate to a maximum length of 1300mmtotal length (TL) (Bruton 1976), a high fecundity, an omnivorous diet and the ability to breathe air (de Moor & Bruton 1988; Cambray 2003). Understanding the biology and population dynamics of this invader would assist in its management and possibly eradication.

- Description: Recruitment, selection and transfer of educators were decentralized after South Africa became a democratic state in 1994 and shifted to School Governing Bodies. The legislation promoted a shared governance and participation of parents in issues that are related to recruitment, selection and transfer of educators, but parents are struggling and facing challenges in performing these tasks as School Governing Body members especially in the Butterworth district, as a result of that Butterworth district is experiencing problems with increasing number of disputes resulting from the appointment of educators after they have been recommended by the School Governing Bodies. This study focuses on the recruitment, selection and transfer of educators in the Butterworth district of the Eastern Cape Province of South Africa. The study sought to reveal the thinking behind government insistence on giving the School Governing Bodies a responsibility to recruit, select and transfer educators knowing fully well that they do not perform this responsibility. A qualitative approach was used to explore and challenge this phenomenon. This approach is concerned with understanding social phenomenon from the participant’s perspective. In depth semi – structured interviews with open ended questions were used to bring the researcher more closer to a more plausible perspective of this phenomenon. Moreover, they were used because they are the most appropriate method to capture the data. The findings revealed that School Governing Bodies are faced with challenges such as: high level of illiteracy, manipulation of School Governing Bodies by school management, unions and candidates, the issue of regionalism and kickbacks, capacity building and empowerment and role played by the Departmental Officials. By conducting this study, we hope that the findings might contribute in identifying the disjuncture between the policy and the practice in issues pertaining to educator recruitment, selection and transfers. , Thesis (MMED) -- Faculty of Educational Sciences, 2011

By conducting this study, we hope that the findings might contribute in identifying the disjuncture between the policy and the practice in issues pertaining to educator recruitment, selection and transfers. , Thesis (MMED) -- Faculty of Educational Sciences, 2011

- Description: The contributions in this volume suggest that "the ethics project in legal education" is increasingly an international one. Even though the strength of commitment by both the profession and the legal academy to "ethics learning" within law schools varies, two fundamental questions confront all who work in this area. First, what is it that we want our students to learn (or, perhaps, in what manner do we want our students to develop) from the teaching of "legal ethics"? Second, how can we create a learning environment that will encourage the nature and quality of learning we think is important?.

- Description: This study was conducted against the backdrop of growing scholarly interest in the epistemic divide between formal, institutionalised knowledge, which guide government interventions in rural community development, and local knowledge, upon which rural communities construct their social existence. The study sought to understand why, despite their resilience and cultural embeddedness in South Africa's rural communities, indigenous self-help groups (SHGs) - as a particular form of indigenous rationality - remained on the periphery of contemporary community development interventions. The study was conducted in the communities of Dabhana, Feni and Mgwanlana in Peddie (Ngqushwa Local Municipality), Eastern Cape. Three SHG variants were eselected: a funeral group (Masingcwabane), an HIV and AIDS support groups, and a financial mutual (mgalelo) – all in the context of government-assisted community development. Empirical data was collected using a mini-survey, focus group discussion, in-depth interviews and key informant interviews. The findings revealed that SHGs were a collective model of indigenous knowledge and social interaction, driven by the belief that through 'sharing', 'reciprocity' and 'collectivism', what would ordinarily be a heavy burden for individuals became 'lighter'. Furthermore, while the institutional framework for community development mandated collaboration between government and SHGs, this framework created a stiff, bureaucratic canvass that alienated SHGs and stifled their operations. The study also found that partnership between the government and SHGs was characterised by fear and distrust on the part of government, and reluctance on the part of SHGs. Government's distrust was premised on the "informality" and "traditionality" of SHGs, and the fear that any investment in SHGs would go to waste. On the other hand, SHGs' reluctance to make themselves amenable to partnership with government seemed like a reaction to a "faulty, culturally insensitive" institutional framework which "delegitimised" grassroots development impulses. The study concluded that there existed in the rural community development arena an epistemic, ideational and practical chasm between government-driven development praxis and age-old indigenous initiatives, and that while the weaknesses of each knowledge domain were accentuated through this divide, development would continue to elude the grassroots communities unless the two knowledge domains interacted with, and leveraged, each other. , Thesis (PhD) (Sociology) -- University of Fort Hare, 2018

- Description: This article explores intersections between understandings of masculinity and nationalism. Etymologically, ‘patriotism’ refers to a love for a fatherland and a patriarchal order; it includes notions of loyalty, honour and a range of qualities often associated with conceptions of masculinity. But if gender remains fixed to these normative constructions, what happens to one’s sense of masculine identity when the national state changes? My interest lies in exploring how white South African men have been repositioned in terms of a shift in their gendered identification, with a reflection on the possibly tragic consequences of maintaining an overly rigid gender role identification. As long as masculinity is embedded within nationalism, it will be caught up within a defensive reactive mode which can turn self-destructive. In order to explore these ideas the article employs as its central metaphor the character of Dawid Olivier, who is the protagonist of Athol Fugard’s Sorrows and Rejoicings (2002).

- Description: In Zoë Wicomb's Playing in the Light, the main character's troubled sense of identity (brought about by her parents' shameful decision to ‘play white’) is viscerally symbolised by her discomfort in her own and others' homes. In her Cape Town apartment she has nightmares about other houses. Her visits to her family home, where her elderly father lives alone, are similarly burdened by presences and memories she finds unwelcoming. And, her extended vacation to the UK, once she has discovered her family's secret, is a choice of “a place in which to cry” (Wicomb 2006: 191).

- Description: To examine the different uses and perceptions of introduced Australian acacias (wattles; Acacia subgenus Phyllodineae) by rural households and communities. Eighteen landscape-scale case studies around the world, in Vietnam, India, Réunion, Madagascar, South Africa, Congo, Niger, Ethiopia, Israel, France, Portugal, Brazil, Chile, Dominican Republic and Hawai‘i. Qualitative comparison of case studies, based on questionnaire sent to network of acacia researchers. Information based on individual knowledge of local experts, published and unpublished sources. We propose a conceptual model to explain current uses and perceptions of introduced acacias. It highlights historically and geographically contingent processes, including economic development, environmental discourses, political context, and local or regional needs. Four main groupings of case studies were united by similar patterns: (1) poor communities benefiting from targeted agroforestry projects; (2) places where residents, generally poor, take advantage of a valuable resource already present in their landscape via plantation and/or invasion; (3) regions of small and mid-scale tree farmers participating in the forestry industry; and (4) a number of high-income communities dealing with the legacies of former or niche use of introduced acacia in a context of increased concern over biodiversity and ecosystem services. Economic conditions play a key role shaping acacia use. Poorer communities rely strongly on acacias (often in, or escaped from, formal plantations) for household needs and, sometimes, for income. Middle-income regions more typically host private farm investments in acacia woodlots for commercialization. Efforts at control of invasive acacias must take care to not adversely impact poor dependent communities.

- Description: This ambitious book begins with the statement ‘By and large, the states of sub-Saharan Africa are failures’ (p. 1) and then sets out to explain state failure in Africa and to provide some ‘rational policy fantasies’ in response to this failure. The book builds on the work of scholars like Robert Jackson, William Reno and Jeffrey Herbst, with the particular focus of Englebert's book being on the domestic implications of the unconditional recognition of the sovereignty of African states. African states are internationally recognised despite lacking the features and not being able to perform the functions typically associated with statehood. Englebert's interest is to examine some of the domestic effects of this unconditional international recognition.

- Description: This study documents validation of vertebral band-pair formation in spotted gully shark (Triakis megalopterus) with the use of f luorochrome injection and tagging of captive and wild sharks over a 21-year period. Growth and mortality rates of T. megalopterus were also estimated and a demographic analysis of the species was conducted. Of the 23 OTC (oxytetracycline) -marked vertebrae examined (12 from captive and 11 from wild sharks), seven vertebrae (three from captive and four from wild sharks) exhibited chelation of the OTC and f luoresced under ultraviolet light. It was concluded that a single opaque and translucent band pair was deposited annually up to at least 25 years of age, the maximum age recorded. Reader precision was assessed by using an index of average percent error calculated at 5%. No significant differences were found between male and female growth patterns (P>0.05), and von Bertalanffy growth model parameters for combined sexes were estimated to be L∞=1711.07 mm TL, k=0.11/yr and t0= –2.43 yr (n=86). Natural mortality was estimated at 0.17/yr. Age at maturity was estimated at 11 years for males and 15 years for females. Results of the demographic analysis showed that the population, in the absence of fishing mortality, was stable and not significantly different from zero and particularly sensitive to overfishing. At the current age at first capture and natural mortality rate, the fishing mortality rate required to result in negative population growth was low at F>0.004/ yr. Elasticity analysis revealed that juvenile survival was the principal factor in explaining variability in population growth rate.
