- Description: This article uses an appraisal analysis of 40 letters to the Daily Sun and The Times newspapers in South Africa to illustrate a reconceptualisation of the Engagement system. It discusses dialogism (Bakhtin 1981), which inspired the creation of the Engagement framework by White (2003), who classified attempts to either align or disalign readers with a writer’s stance. Contrary to the options for dialogic Engagement proposed by Martin and White (2005) and White and Don (2012), the data suggests that not all Engagement strategies carry equal power of alignment, as the framework’s systemic layout implies. This prompts a re-thinking of the Engagement categories as occurring along a continuum of their strength.

- Description: Union politics remain central to the new century. It remains central because of the ongoing importance of unions as mass movements, internationally, and because unions, like other popular movements, are confronted with the very real challenge of articulating an alternative, transformative vision. There is much to be learned from the historic and current tradition of anarcho-and revolutionary syndicalism.

- Description: Publisher version , We utilised stable isotope ratios to assess differences in diet among three indigenous and syntopic rocky shore suspension-feeders (mussels Perna perna, barnacles Tetraclita serrata, and polychaetes Gunnarea gaimardi). We also determined the spatial and temporal variability in the suspension-feeder diets by collecting specimens on two occasions from two regions adjacent to hydrologically distinct river mouths (i.e. one with larger annual freshwater throughput than the other). The results showed that the isotopic niches (used as proxies for trophic niches) of the three species did not overlap and that the barnacles occupied a trophic position (3.4) well above those of the mussels (2) and polychaetes (2.6). We ascribed the interspecific differences primarily to the disparate feeding mechanisms used by the species. Large-scale regional (~50 km) differences in suspension-feeder diets were apparent, but not small-scale (up to a few km north and south of each estuary mouth). The regional differences in diet resulted from the increased availability of estuarine-origin suspended particulate matter (SPM) and zooplankton in the region adjacent to the river with relatively larger freshwater output, although overall incorporation of zooplankton versus mixed SPM into consumer diets was relatively consistent between regions and through time. Temporal shifts in suspension-feeder diets were apparent from stable carbon isotope ratios in the consumers. Our results showcase the measurable effects of regional-scale processes that can alter the food sources for dominant primary consumers in the rocky intertidal, thus potentially affecting entire food webs through bottom-up processes. The clear evidence for trophic niche partitioning offers valuable insights into how potentially strong competitors can coexist.

The past 22 years have seen an ongoing process of settling down and construction of necessary buildings. This paper seeks to explore aspects of philosophical and architectural influences that served as some of the foundation stones for creation of an eclectic series of buildings, including their home, visual arts studios, a gallery, a community theatre and guest accommodation. A review of these buildings will show that Van der Merwe and Lloyd have developed an idiosyncratic construction style that incorporates alternative technology with empathetic use of natural resources, which results in organically flowing living and working spaces that are fit for purpose, have substantial presence and have minimal environmental impact.

- Description: In terms of nationality, Alexandra Fuller is difficult to pigeonhole. She was born in England but from age two was brought up in Southern Africa (mostly Rhodesia). She married an American working in Zambia and then moved to Wyoming to raise a family. She has written three books about her family, their peripatetic life, and the violence of decolonizing Africa. The success of these works has made her one of the few African female nonfction writers to gain an international audience. Fuller’s longform journalism has been published in Granta and the Guardian in the United Kingdom, and in the New Yorker, Harper’s, National Geographic, Byliner, and Vogue in the United States. This paper traces the arc of a writer transcending her continent to break into the competitive American magazine market, portraying the complex land from which she has come for a foreign audience.

- Description: Rotenone, a naturally occurring ketone, is widely employed for the management of invasive fish species. The use of rotenone poses serious challenges to conservation practitioners due to its impacts on non-target organisms including amphibians and macroinvertebrates. Using laboratory studies, we investigated the effects of different rotenone concentrations (0, 12.5, 25, 37.5, 50, 100 μg L-1) on selected invertebrate groups; Aeshnidae, Belostomatids, Decapods, Ephemeroptera, Pulmonata and zooplankton over a period of 18 hours. Based on field observations and body size, we hypothesized that Ephemeropterans and zooplankton would be more susceptible to rotenone than Decapods, Belostomatids and snails.

Art investment as a portfolio diversification strategy in South Africa

- Description: publisher version , Art has been suggested as a good way to diversify investment portfolios during times of financial uncertainty. The argument is that art exhibits different risk and return characteristics to conventional investments in other asset classes. The new Citadel Art Price index offered the opportunity to test this theory in the South African context. The Citadel index uses the hedonic regression method with observations drawn from the top 100, 50 and 20 artists by sales volume, giving approximately 29 503 total auction observations. The Index consists of quarterly data from the period 2000Q1 to 2013Q3. A VAR of the art price index, Johannesburg Stock Exchange all-share index, house price index, and South African government bond index were used. Flowing from the VAR results, additional analyses included variance decomposition, impulse response, and, to determine volatility, variance and standard deviation measures for each index. Results show that, when there are increased returns on the stock market in the previous period and wealth increases, there is a change in the Citadel Art Price Index in the same direction. This finding is consistent with Goetzmann et al. (2009), who reported that there is a strong relationship between art and equity markets and that art price changes are driven by capital gains and losses. No significant difference was found between the house price index and the art price index, and neither between the art and government bond price indices. Overall, the South African art market does not offer the opportunity to diversify portfolios dominated by either property, bonds, or shares.

- Description: We examined how human harvesting impacts on managed areas affect the abundance and size distribution of the edible mangrove shellfish Anadara granosa and Polymesoda spp. in the Roviana Lagoon, Solomon Islands. We tested two hypotheses: (1) in areas permanently and temporally closed to human exploitation, abundance and size distribution of these shellfish species is significantly greater than in sites open to exploitation and (2) moderate human disturbance of shell beds, particularly of Polymesoda spp., increases their abundance. Firstly, we studied perceptions of environmental states and processes coupled to foraging and management interventions to assess sociocultural influences on harvesting practices and ascertain the types of management regime that people would consider in a context where poaching and interloping are common practices. Secondly, we compared shellfish abundance and shell size from areas that were permanently protected, temporally reserved for communal harvest, and permanently open for exploitation. Thirdly, drawing from women’s local knowledge, we measured the abundance of Polymesoda spp. in relation to mud compactness in quadrats across the three management regimes. Results showed that both species were significantly more abundant in permanent and temporally closed sites than in open sites. In the mud compactness study, however, while shell abundance was greater in moderately compacted quadrats, there was no statistical relationship between mud compactness and shell abundance within or across the three management regimes. Results suggest that even under the strong impacts of poaching, temporally closed areas have more clams than open areas and are as effective as areas that are permanently closed nominally. The results also suggest that human harvesting regimes can influence the effectiveness of local management decisions and thus are important when designing community-based conservation programs in the Solomon Islands and other Pacific Islands.

- Description: This study was conducted at a small ‘research-led’ institution in South Africa. The data indicate that women produce less research than men and have low levels of professional self-esteem. Factors such as accrual of social capital, family responsibilities and self-esteem are constraints experienced by women academics in pursuing research careers. Mentoring was found to facilitate research career development and improve levels of self-esteem. Improved self-esteem enables women to promote themselves within their institutions and in the research arena. The role of the head of department with mentoring as a key function emerged as an influential structure for the career advancement of women academics. However, these leadership positions are significantly dominated by men and this appears to affect the amount and nature of mentoring women academics receive.

- Description: Life Orientation sexuality education in South Africa faces many pedagogical challenges, not least among which is that it is sometimes perceived as irrelevant to learners' real interests and concerns. Learners report that the content is repetitive and that they learn more from peers than from the reiterated lessons of risk and disease avoidance that permeate sex education messages. In this article we describe the world of the study site - a 'single sex' school - as consisting of diverse informal student sexual cultures in which repertoires for the development of learner sexual identities are developed, negotiated and transmitted. The study is based on detailed ethnographic immersion in the study site which generated rich data drawn from in-depth interviews, focus groups, observations and solicited narratives. We argue that even the enlightened, tolerant 'best practice' form of sexuality education that takes place at the study site fails to take diverse learner identities, lifeworlds and experiences seriously as a pedagogic starting point, but rather tends to homogenise learners and to impose on them what they need to learn. A more empowering form of sexuality education would take seriously how young people understand themselves as sexual subjects located in unequal ('raced' and classed) social contexts.

- Description: Using network telescopes to monitor unused IP address space provides a favourable environment for researchers to study and detect malware, denial of service, and scanning activities on the Internet. This research focuses on comparative and correlation analysis of traffic activity across five IPv4 network telescopes, each with an aperture size of /24 over a 12-month period. Time series representations of the traffic activity observed on these sensors were constructed. Using the cross- and auto-correlation methods of time series analysis, sensor data was quantitatively analysed with the resulting correlation of network telescopes’ traffic activity found to be moderate to high, dependent on grouping.

- Description: publisher version , From Introduction: The aim of this article is to situate the importance of orality in rural communities within the paradigm of Technauriture, which is defined below. The chapter will also explore/describe the process of orality supported through community meetings, oral histories, and story-telling, and how it interacts with the recording process facilitated through modern technology, as well as the return of the oral material via technology. These objectives will be pursued as part of empirical data collected at Tshani, an area falling within the in Mankosi tribal authority in the Eastern Cape Province of South Africa. Mankosi’s twelve villages are inhabited by amaXhosa people and is situated in the Ngqeleni district in the former Transkei region. Mankosi is about 76 kilometres away from Mthatha, the major city in that area. These villages are under the Nyandeni Local Municipality and are regarded as very disadvantaged. There is poor sanitation, gravel roads, and few local people have access to electricity. Most of the villagers depend on government support grants. These include Child Support Grants, Old Age Grants, Disability Grants, and Foster-Care Grants. Furthermore, most of the community is involved in small-scale agriculture for survival. People often move, temporarily, from their village to towns in order to gain employment, including domestic work and working on the mines in the mineral rich Gauteng Province. They send cash remittances home to their families. The primary technological devices that people in the village are familiar with would be radio and the cell phone. Even television sets are relatively uncommon.

Sculpting with fire: celebrating ephemerality at AfrikaBurn 2015 in the Tankwa Karoo, South Africa

- Description: Land art, and some installation art, is usually aimed at relatively temporarily manipulating the surface of the earth. AfrikaBurn takes place annually in the near-desert of the Tankwa Karoo, South Africa. It is a communal event unique to Africa, and manifests as a fleeting week-long series of interventions in the natural environment, partially aimed at creating and then actively destroying free-standing public sculptures, some of which are huge and intricate. AfrikaBurn gives any one of the thousands of participants an opportunity to be inspired on any scale to generate artworks that take into account a principle that no debris whatsoever is left behind on the surface of the earth after a week-long celebration of creative energies. Unlike, for instance, an artwork built on the edge of the Indian Ocean in the Eastern Cape, where rough tidal seas would ensure gradual destruction, at AfrikaBurn, the sacrificial method of choice is controlled rapid burning, under the direction of a specified firemaster. This paper seeks to unbundle some aspects of land and installation art in Southern Africa with specific reference to AfrikaBurn 2015 events and anti-fracking initiatives. This is within a context that takes into account recognition that even seemingly durable public sculptures are subject to change and may even physically disappear with the passing of time.

- Description: Spotted ragged-tooth sharks Carcharias taurus occur along the southern and eastern coasts of South Africa. We report on movements of juveniles and adults within a known nursery area on the Eastern Cape coast using acoustic telemetry. The focus area of the study was Algoa Bay, where six VEMCO VR2 ultrasonic receivers were placed at known shark aggregation sites. An additional receiver was placed at Thunderbolt Reef, approximately 2 km southwest of Cape Recife, the south-western tip of Algoa Bay. Single receivers were also deployed at Port Alfred and East London, some 45 and 170 km north-east of Algoa Bay, respectively. VEMCO acoustic V16 tags were either surgically implanted (n = 37) or attached externally using dart heads (n = 6) between January 2003 and March 2006. Surgically implanted tags were recorded over multiple months and years, whereas external tags were probably lost shortly after tagging because they were detected for very short periods. Sharks moved extensively between the sites and revisited monitored reefs over time-periods of months and years, demonstrating philopatry. Departures from and arrivals at reefs were more frequently recorded at sunset and sunrise, respectively. Sharks were detected throughout the year but they spent more time at aggregation sites during summer and autumn, indicating seasonal abundance in agreement with previous findings. Movements away from study reefs were attributed to either foraging or movements to other reefs. Despite extensive movements around the bay and beyond, both juveniles and adults exhibited philopatry to the study area over multiple years.

- Description: Research has shown that children are the greatest users of natural areas and that childhood experiences strongly shape adults’ environmental values. This project was designed to ascertain children’s environmental uses and perceptions in two rural villages in the Eastern Cape, South Africa, utilising children’s use of the environment for play and their sense of place as key focus areas. Several factors influenced children’s environmental use, including safety fears, increased consumption of western media and environmental restrictions imposed by the state, revealing how South Africa’s high level of violence against women and children contributes to gendered environmental use and knowledge, and bringing about concern for children’s cultural identity in an increasingly westernised world.

- Description: Five to seven subspecies of Antarctic Tern (Sterna vittata) are recognised, with at least three (S. v. vittata, S. v. tristanensis and S. v. sanctipauli) wintering in South Africa. Morphological characters used to define these subspecies are not perfectly reliable, but fidelity to nesting site suggests they could be genetically distinct. We used morphological data and DNA to investigate the validity of subspecies. We further used stable isotope analysis of feather samples collected from the non-breeding grounds in South Africa to attempt to ascertain the population of origin. Nuclear and mitochondrial DNA sequence data identified two major genetic clades: one mostly comprised individuals partially or completely matching the morphological description of S. v. tristanensis, the other included individuals from S. v. vittata and S. v. sanctipauli. Stable isotope values indicated that juveniles originated from at least three populations. Irrespective of their morphological and genetic characteristics, most immatures moulted in Antarctic waters, and adults moulted in various habitats. Their colony of origin could not therefore be inferred from stable isotope values from feathers. Results indicate that morphological groupings may reflect a north-south cline across the Indian Ocean. Adequate conservation strategies require rigorous reassessment of the currently accepted subspecies, including DNA analyses of samples from the breeding grounds, particularly on Amsterdam and St Paul Islands.

- Description: This edited work has gathered together contributions on how to transform universities in South Africa; as many are struggling to shift their institutional culture. In a South African context, transformation means to attempt to change higher education institutions such that they no longer reflect the values promoted by apartheid but rather reflect the values embodied in South Africa's 1996 Constitution. Institutional culture is the main subject for discussion in this book. In order to transform South Africa's universities, the contributors begin by analyzing the idea of what a university is, and relatedly, what its ideal aims are. A second theme is to understand what institutional culture is and how it functions. Moreover, transformation cannot occur without transforming the broader cultures of which they are a part. Related to this theme is a general concern about how contemporary moves towards the instrumentalization of higher education affect the ability to transform institutions. These institutions are being pushed to conform to goals that are outside the traditional idea of a university, such as concerns that universities are being 'bureaucratized' and becoming corporations, instead of a place of learning open to all. In conclusion it can be said that the contemporary South African academic community has an opportunity to recreate itself as the end of apartheid created space for engaging in transformative epistemic projects. The transformation of the tertiary sector entails a transformation of institutional cultures.

- Description: publisher version , In recent years there have been calls both for building the knowledge base of academic development (AD) and for systematic induction of newcomers to the field if AD is to advance as a professional and an academic field. Despite the importance and complexity of AD, induction of novice academic developers remains mostly informal and predominantly focuses on the practices of the field. We argue that more-experienced academic developers have an obligation to provide formal and systematic routes into the field and its knowledge base than is currently the case. One way of doing this is through offering a formal course for growing the next generation of academic developers. Such a course could equip newcomers with a more solid and shared knowledge base, thus contributing to shaping the epistemic spine of AD. In this paper, using Maton's Legitimation Code Theory, we offer an analysis of an existing course aimed at equipping novices with the theoretical and practical knowledge to enable them to solve some of the problems in higher education. From this analysis have emerged general principles that could inform the selection, sequencing and pacing of knowledge in a formal course for academic developers.
