- Description: Intrusion Detection is essential in modern networking. However, with the increas-ing load on modern networks, the resource requirements of NIDS are significant. This paper explores and compares the requirements of Snort and Bro, and finds that Snort is more efficient at processing network traffic than Bro. It also finds that both systems are capable of analysing current network loads on commodity hardware, but may be unable to do so for higher bandwidth networks. This is ben-eficial in a South African context due to the increasing international bandwidth that will come online with the launch of the SEACOM Cable, and local projects such as SANREN.

- Description: Owners and vendors are increasingly publishing their materials in digital form. Because such materials can be exactly copied, a mechanism is required that will protect the legitimate owners of these works, by providing proof of original ownership. Digital watermarking has now become one accepted method of establishing ownership of digital materials. The owner of a work embeds a pattern, called a digital watermark, in the content. This embedded watermark is normally undetectable, but its presence can be demonstrated by the owner of the work or his agent, thereby proving ownership. Digital watermarking has been used for many types of multimedia content, primarily audio, video and flat images. Recently, interest has been shown in applying digital watermarking schemes to 3D surfaces, in various formats. In this paper, we examine a method whereby a digital watermark can be embedded in a Bezier surface. A prototype watermarking method for such surfaces is presented, with some experimental results, and a discussion of directions for future research.

- Description: Surfacing the connections between science engagement, engaged science, and sustainability sciences, we urge a re-evaluation of sustainability science's beneficiaries and goals, by advocating a transdisciplinary approach to address sustainability challenges, based on a relational ontology. Thinking with posthumanist, feminist new materialist and Black feminist theories, we consider the importance of multispecies attention and empathy in scientific research. We propose a concept of evolving new perceptual organs in humans to enhance collective responsiveness, inspired by the lateral line organ in fish and their collaborative intelligence for navigating contemporary social and ecological crises and injustices in 'hot messes'.

- Description: The article focuses on active anting in captive Cape white-eyes Zosterops pallidus. In this study, observation of captive birds at close quarters enables to test some of the stimuli that could elicit this behavior. When anting, birds either brush ants through their plumage or allow ants to crawl over them. Anting has been recorded in more than 160 species of passerine birds worldwide. Nevertheless, it is rarely observed in the wild, perhaps because the actions resemble preening movements or dust-bathing. Experiments were designed to clarify whether white-eyes ant before eating ants, and whether anting is correlated with moult in this species.

- Description: A southern race of the Olive Thrush, Turdus olivaceus smithi Bonaparte, has recently been proposed as a full species, the Karoo Thrush Turdus smithi (Bowie et al. 2003). Some of the published information on the Olive Thrush Turdus olivaceus olivaceus thus pertains to the Karoo Thrush (eg Kopij 2000), whereas other information deals specifically with the Olive Thrush (eg Winterbottom 1966, Bonnevie et al. 2003). We have ringed, recaptured and recovered both Olive and Karoo Thrushes in the Eastern Cape since 1986, and the two taxa are markedly different in this region. We describe some differences in appearance of the two populations from these data, and compare mass and wing length of living birds, as well as culmen and tarsus lengths of museum specimens from the East London Museum, South Africa. The collection sites of the museum specimens were mapped using ArcView 3.1 (ESRI 1996) together with the ringing sites (Figure 1). Areas of potential sympatry are Oudtshoorn (33 25’S, 22 11’E) and Patensie (33 45’S, 24 48’E).

- Description: Figs, the fruits of Ficus species (Moraceae), support diverse communities/assemblages of fig wasps belonging mainly to the families Agaonidae and Eurytomidae (Boucek et al. 1981; Compton and Hawkins, in press). Southern African fig wasp communities are composed mainly of species associated with the ovules of the plants, either as ovule-gallers or their parasitoids, although some species also gall fig primordia or the walls of the figs (Compton and van Noort 1992). The trophic relationships of only a few fig wasp species have been determined (Compton and van Noort 1992), but these suggest that the various subfamilies of fig wasps are generally consistent in that they contain either gallers or parasitoids. Amongst the gall-forming species are the Epichrysomallinae and Agaoninae (Agaonidae)(Boucek 1988). Eurytomids provide an exception to this general uniformity of larval feeding methods. For example, Sycophila Walker is a major genus of fig wasp eurytomids which includes species that are either gall-formers or parasitoids (Claridge 1959; Boucek 1988).

- Description: The objective of this paper is to assess the current state of Container-Based Emulator implementations on the Linux platform. Through a nar-rative overview, a selection of open source Container-Based emulators are analysed to collect information regarding the technologies used to construct them to assess the current state of this emerging technology. Container-Based Emulators allows the creation of small emulated net-works on commodity hardware through the use of kernel level virtualiza-tion techniques, also referred to as containerisation. Container-Based Emulators act as a management tool to control containers and the ap-plications that execute within them. The ability of Container Based Emu-lators to create repeatable and controllable test networks makes it ideal for use as training and experimentation tools in the information security and network management fields. Due to the ease of use and low hard-ware requirements, the tools present a low cost alternative to other forms of network experimentation platforms. Through a review of cur-rent literature and source code, the current state of Container-Based Emulators is assessed.

The seven case studies of how applied theatre practices can be framed as research methodologies are practically and theoretically useful for students, practitioners and scholars engaged in community-driven, socially engaged theatre work. The book argues a particular approach to arts based research which offers alternatives to traditional research tools such as ‘the interview’ (which often result in participants giving a researcher what they think they want to know or hear) and provides a range of aesthetic research methodologies that aim to harness the language of theatre and performance as an empowering and resistant research tool.

- Description: Few teachers and learners have any 'sense of ownership' of 'the place' in which school geography is located. Notwithstand-ing the apparent neutrality of a subject that is concerned with information about climate, settlement, or the economy, these 'geographies' have until now been located, in a political and physical landscape of a South Africa that did not 'belong' to the people at large. This has effectively meant that geography has been taught from a perspective that is perceived to be alien and even hostile, and is therefore often considered to be irrel-evant. Teaching resources and strategies have served to strengthen this sense of alienation. Textbooks are, in style and content, almost exclusively situated in a white South Africa of which many pupils have little or no experience. Furthermore, because geography has been taught 'from a book' with field-work the exception rather than the rule, few children have any concept of geography as' that which is all around us' (Mapha-phuli 1992; King 1994). It is part of the missed opportunities of South African geography that indigenous cultural concepts re-lating to the notion of place have not been widely recognised. The combination of a lack of a sense of political ownership and perceived 'eurocentricity' has had a further impact on the atti-tudes of pupils and learners.

- Description: The conventional methods of animal identification can be replaced with a semi-automatic image analysis tool, which distinguishes individuals based on their unique markings. A flexible framework for the analysis must encompass a combination of relevant features with interchangeable animal-specific modules. Developing a Java-ImageJ plug-in alleviates routine functionality, but enforces some degree of conformity. Zebra photographs are used as the initial data under consideration. De-interlacing, adaptive thresholding, smoothing and sharpening are identified as beneficial pre-processing steps. Binarisation and sequential thinning are discussed as essential processing stages. Pattern extraction and matching is based on vectors relative to a manually defined region of interest. Provision for enhancing the system to allow fully automatic processing must be made.

- Description: With developments in the Internet and Web-based technologies, dis-tinctions between traditional markets and the global electronic market-place-such as business capital size, are gradually being narrowed down. It is recognized that in the Information Age, e-Commerce is a powerful tool for economic growth of developing countries. While there are indications of e-Commerce patronage among large firms in devel-oping countries, there seems to be little and negligible use of the Inter-net for commerce among small and medium sized firms. However, many of these e-Commerce projects in marginalized areas fail as a re-sult of lack of the required resources to support ICTs. Different ways have been suggested for marketing products online and to create cus-tomer loyalty. This paper discusses a marketing and customer loyalty strategy through a real-time interactive negotiation application, aimed at improving the existing e-Commerce platform. The e-Commerce platform has been deployed as part of the Siyakhula Living Lab ICTD project which is undertaken for the Dwesa community in the Eastern Cape province of South Africa.

- Description: Insects are a poor source of dietary calcium and since they are seasonally abundant, it has been suggested that calcium availability may play a significant role in controlling the timing of reproduction in insectivorous bats. To assess the possible role of dietary calcium, we have measured bone calcium concentrations in female and male long-fingered bats (Miniopterus schreibersii) through a full reproductive cycle. The results indicate that winter was not a period of calcium stress and, therefore, that seasonal changes in insect abundance and dietary calcium availability are not a satisfactory explanation for the occurrence of delayed implantation in the long-fingered bat. Bone calcium concentrations of females did not differ significantly throughout pregnancy, indicating that the insects available in winter and early summer were sufficient to meet the calcium demands of pregnancy. Lactating females had the lowest bone calcium concentrations of all specimens, supporting the suggestion that lactation is indeed a period of severe calcium stress in aerial insectivores. We conclude that parturition is probably timed so that lactation coincides with the period of maximal insect abundance and corresponding dietary calcium availability.

- Description: Emerging and re-emerging vector-borne diseases caused by viruses, bacteria, protozoa and other pathogens have increased dramatically throughout the world in recent years. Among the factors that have undoubtedly contributed to this scenario are environmental change, increased international trade and travel, human-induced changes in land use, technical innovations in food processing, microbial adaptation and insecticide resistance. Such diseases pose a serious threat to both human and animal health, and measures for their surveillance and control urgently need to be implemented. In view of the fact that infectious diseases are currently appearing in countries where they did not previously exist or are reappearing after a period of decline, this book is both timely and crucial to our understanding and awareness of this serious problem.

- Description: This study presents results from stomach content analysis of 123 largemouth bass, Micropterus salmoides, sampled at the mouth of the fishway leading into a 3 m high weir at the tidal limit of the Kowie River, Eastern Cape Province (33°32‘39“S, 26°46‘ 52.3“E). Stomach contents from small (120–240 mm fork length, FL) and large (250–440mm FL) fish were analysed separately. Fish were the dominant prey item in small bass, followed by terrestrial insects and Potamonautes sp. In large bass, Potamonautes sp. dominated the stomach contents, while fish were less dominant and other prey items were considered incidental. Estuarine fish species, Monodactylus falciformis, and two species of the family Mugilidae, Mugil cephalus and Myxus capensis, were the most common fish prey in both size classes of M. salmoides. These results are the first evidence of the alien M. salmoides preying on these three indigenous estuarine species during their migration into fresh water.

- Description: Cliff-nesting pale-winged starlings (Onychognathus nabouroup) gather on the cliff tops to perform Group Displays which include both aggressive and courtship elements: Hopping, Wing Stretching, Wing Drooping, Wing Flicking, Staring, Head Forward Threat and Butterfly Fluttering. These displays occur throughout the year, most frequently in the late afternoon. We suggest that this behaviour may be important in pair formation, and in establishing dominance relationships between birds breeding at the same site.
