- Description: The mussel Mytilus galloprovincialis is invasive worldwide, has displaced indigenous species on the west coast of South Africa and now threatens Perna perna on the south coast. We tested the hypothesis that Mytilus will replace Perna by examining changes in their distribution on shores where they co-exist. Total cover, adult density, recruit density, recruit/adult correlations and mean maximum lengths of both species were measured in 2001 at two contrasting sites (Plettenberg Bay and Tsitsikamma) 70 km apart, each including two locations 100 m apart. Cover and density were measured again in 2004. Total mussel abundance was significantly lower in Tsitsikamma, and recruit density was only 17% that of Plettenberg Bay. Abundance and cover increased upshore for Mytilus, but decreased for Perna, giving Mytilus higher adult and recruit density and total cover than Perna in the upper zones. Low shore densities of recruits and adults were similar between species but cover was lower for Mytilus, reflecting its smaller size, and presumably slower growth or higher mortality there. Thus, mechanisms excluding species differed among zones. Recruitment limitation delays invasion at Tsitsikamma and excludes Perna from the high shore, while Mytilus is excluded from the low shore by post-recruitment effects. Recruitment limitation also shapes population structure. Recruit/adult correlations were significant only where adult densities were low, and this effect was species-specific. Thus, at low densities, larvae settle or survive better near adult conspecifics. After 3 years, these patterns remained strongly evident, suggesting Mytilus will not eliminate Perna and that co-existence is possible through partial habitat segregation driven by recruitment limitation of Perna on the high shore and post-settlement effects on Mytilus on the low shore.

- Description: On 6th February 1838 the life of Piet Retief moved towards its great climax and death along with those of his entourage at the hands of Dingaan's warriors. Retief had gone to Umgungundlovu, Dingaan's kraal, to receive from Dingaan a cession of the land between the Tugela and the Umzimvubu Rivers. The grant of this land is said to have been made in a document dated Feb. 1838 but which circumstantial evidence suggests might have been signed on the 6 Feb. The document which has been regarded by some as a sort of title deed to Natal is an enigma which Retief has bequeathed to historians.

- 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.

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. Te 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. Tis 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: The Functions of Evil Across Disciplinary Contexts explores answers to two important questions about the age-old theme of evil: is there any use in using the concept of evil in cultural, psychological, or other secular evaluations of the world and its productions? Most importantly, if there is, what might these functions be? By looking across several disciplines and analyzing evil as it is referenced across a broad spectrum of phenomena, this work demonstrates the varying ways that we interact with the ethical dilemma as academics, as citizens, and as people. The work draws from authors in different fields—including history, literary and film studies, philosophy, and psychology—and from around the world to provide an analysis of evil in such topics as deeply canonical as Beowulf and Shakespeare to subjects as culturally resonant as Stephen King, Captain America, or the War on Terror. By bringing together this otherwise disparate collection of scholarship, this collection reveals that discussions of evil across disciplines have always been questions of how cultures represent that which they find socially abhorrent. This work thus opens the conversation about evil outside of field-specific limitations, simultaneously demonstrating the assumptions that undergird the manner by which such a conversation proceeds.

- Description: This paper investigates how the music nationalism promulgated by the ZANU-PF regime's former Minister of Information and Publicity, Jonathan Moyo, appropriated history and culture in its relentless effort to convince the citizenry that the on-going crisis in Zimbabwe is a continuation of the liberation struggle. It documents how Moyo's propagandised ‘patriotic history’ was written into song lyrics and used in frequently televised propaganda videos and CD/cassette releases to create a music nationalism that appropriated the music of the 1970s Second Chimurenga struggle, then performed to resist colonial oppression, and used it as propaganda intended to maintain the current oppressive regime's grip on political power. It argues that the appropriation of indigenous song/dance forms and the ‘chimurenga music’ of the liberation war has failed to achieve unification of the nation; and that rather, the propaganda's manipulation of memory has offended the Shona cultural aesthetic that requires songwriters to speak the truth of their experience in their music.

- Description: The decline in world energy consumption caused by the twin oil price hikes of 1973 and 1979 checked development in the major market economies and triggered the process of industrial restructuring that has so profoundly affected all sectors and all regions. ore efficient use of more expensive energy and strategic policy changes have made major contributions to easing the historical reliance upon energy inputs - especially in the case of oil. As a result the ratio between energy consumption and growth of gross world production has diminished by nearly 25 % over the past fifteen years. It has been estimated that full use of available energy-efficient technologies could cut per capita energy use by as much as 50% without impeding economic growth. The extent to which these gains are realized will depend upon a wide variety of economic and developmental factors, among which the price management of fuels is a very important one. here has also been a change in the industrial mix of the major OECD economies with the decline of old industries using high energy imputs and the rise of high technology sectors with different and lower energy requirements. The shift of much basic manufacturing to new locations in the developing world and to the hitherto centrally planned economies is likely to precipitate a further important change in energy requirements. emand for energy is forecast to continue to grow at only about half the rate of general economic growth over the short to medium term. Consumption is very uneven on a world scale, however. In 1988 the world consumed energy equivalent to some 8 billion tonnes of oil (Tonnes Oil Equivalent, or TOE) - an average of 1.3 tonnes for every man, woman and child on Earth. While citizens of the USA will consume an average of 8 TOE per capita, however, the average for both Japan and Western Europe is around 3 TOE, while people in the Third World still rely on fuelwood and dried animal dung as important energy resources, consuming only a small fraction of a TOE each in many cases.

Integrating writing development in curricula: writing intensive project case studies
- Authors: Thomson, Carol
- Date: 2017
- Language: English
- Type: Book , text
- Identifier: http://hdl.handle.net/10962/59580 , vital:27628
- Description: These case studies come from work done in the Writing Intensive Project (WIP) from its inception in 2013 until 2016 when formal funding from a Teacher Development Grant from the National Department of Higher Education ended. The project was unique for Rhodes University as it was the first time an intervention of this kind had ever been directed specifically at undergraduate writing development and support in the disciplines, and secondly, that participation by discipline-based academics in the project was entirely voluntary, thereby exemplifying a significant level of agency.

The battle for Cassinga : conflicting narratives and contested meanings
- Authors: Baines, Gary F
- Date: 2007
- Language: English
- Type: Conference paper
- Identifier: vital:6156 , http://hdl.handle.net/10962/d1007073
- Description: Nearly thirty years ago the name Cassinga (or Kassinga) came to the attention of the world. At the time the name evoked a range of responses, from outrage to grief to the celebration of military bravado. It still does so. And Cassinga will continue to elicit such responses as long as participants and witnesses are alive and the events remain part of living memory. Obviously perpetrators and survivors remember the events of 4 May 1978 differently. Memory is, after all, selective. The recollections of participants and witnesses are framed by personal and political agendas. This much is abundantly clear from the conflicting accounts of Cassinga that appear in the media and literature, especially the exchanges that take place between parties with a stake in how the events are remembered. Thus a report headlined “Battle of Cassinga still rages” published on the 29th anniversary suggested that the events are still shrouded in controversy and that there is no agreement about what transpired in the southern Angolan town. The title of this paper reflects my concern with the battle for rather than of Cassinga. The choice of preposition is intended to signify the ongoing contestation over the meaning of Cassinga.

The reward preference/motivation paradox and implications for performance and education
- Authors: Snelgar, Robin
- Subjects: Employee motivation , Incentive (Psychology) , f-sa
- Language: English
- Type: text , Lectures
- Identifier: http://hdl.handle.net/10948/21897 , vital:29799
- Description: The focus on reward preference has emerged essentially as a result of the need to identify what really motivates productive behaviour within the workplace, despite the fact that other variables such as retention and attraction have also been taken into consideratin. Motivation has always been an issue of great interest to both reserachers as well as practitioners within the organizational setting, the intention being to find ways to improve performance and, more specifically, particular types of performance within the world of work. Ultimately, the issue has always been how to understand, predict, shape and control human behaviour.

- Date: 2005
- Language: English
- Type: Article
- Identifier: vital:6136 , http://hdl.handle.net/10962/d1011588
- Description: The aim of this paper is to provide an overview of the semantic and syntactic characteristics of the discourse marker actually, and then to describe and explain how it is used by mothertongue (MT) Xhosa speakers who have learned English as an additional language. Such a description may provide a useful benchmark for comparison with MT norms. The source of data for the study is a corpus of approximately half a million words of transcribed spontaneous dialogue between Xhosa English speakers.

Shaking a hornets' nest: pitfalls of abortion counselling in a secular constitutional order–a view from South Africa
- Authors: Vincent, Louise
- Date: 2011
- Language: English
- Type: text , article

- Description: There exists an enormous gulf between the aspirations of South Africa's abortion legislation – among the most liberal in the world – and its implementation. One weakness in the provision of abortion services in South Africa is the absence of comprehensive abortion counselling services. On the face of it, the idea that counselling ought, as a matter of course, to be a significant component of a country's termination of pregnancy service provision, seems both straightforwardly sensible and politically innocent. This paper describes how abortion counselling has historically, in many different contexts, been saturated with questionable assumptions about women and their bodies. Counselling has more often than not been deployed, either as the formal policy of states or through informal mechanisms, as a means of curbing the right to abortion rather than deepening the meaning of that right. Differing approaches to counselling emerge as a reflection of contestations over reproductive and gender politics. Specifying an appropriate model for the provision of state-sponsored abortion counselling in the public health sector of a secular constitutional state provokes more of a hornet's nest of dilemmas than is sometimes supposed.
