This lecture looks at the role of the media in promoting an enhanced citizenship, locating the debate within the discourse of development and freedom. It identifies threats to what can be characterised as a 'media-citizens compact', such as media over-commercialisation. It concludes that public-service media are cardinal to the enjoyment of citizenship rights and freedoms.

This presentation gives a descriptive and analytical overview of the implementation of the Rhodes eResearch Repository system at Rhodes University, building on an ETD programme started in 1998. This project involves staff from Rhodes University Library and the Information Technology Division, with the approval of the Dean of Research. With the support of Management and a strong university IT culture of using open source software, Rhodes University Library planned the implementation of the system without major bureaucratic obstacles. We did, however, experience limited budgetary support and severe staff constraints. This poster aims to encourage institutions with limited resources to start IR programmes and emphasizes the short space of time required “to get up and go”.

This inaugural lecture is in two parts: each related to a different nexus of the four types of scholarly activity. The first reflects on my career and is an examination of how I have developed as a teacher and learner. The key scholarly activities being discovery, integration and teaching. The second part reflects on the evolution of my research interests and leads up to an examination of the land question in South Africa. The scholarly activities in this part of the lecture are discovery, integration and application.

What role can the commercialisation of natural resource products play in the efforts to reduce poverty and vulnerability and how can this be enhanced? With poverty alleviation at the top of the global development agenda, this is a question posed by many scholars, practitioners, donor agencies and government departments operating at the environment-development interface. However, recent commentary on this issue is mixed and ambiguous, with some observers being quite optimistic regarding the potential of these products, while others hold a counter view. This thesis explores the livelihood contributions and poverty alleviation potential of four products traded locally in the Bushbuckridge municipality, South Africa; namely traditional brooms, reed mats, woodcraft and a beer made from the fruits of Sclerocarya birrea. A common approach, employing both quantitative and qualitative methods, was used to investigate the harvesting, processing and marketing arrangements, sustainability and livelihood contributions of each product. The results illustrate that any inference regarding the potential of the trade to alleviate poverty depends on how poverty is defined and interpreted, and on whether the role of these products is assessed from a holistic livelihood perspective that includes notions of vulnerability, alternatives and choice, diversification and the needs of rural producers themselves. Overall, the products studied were key in enhancing the livelihood security of the poorest members of society, forming an important safety net and assisting in raising household incomes to levels equivalent to the wider population, but generally were unlikely, on their own, to provide a route out of poverty. However, there were notable exceptions, with marked variation evident both within and across products. Incomes often surpassed local wage rates, and a minority of producers were obtaining returns equivalent to or greater than the official minimum wage. Other benefits, such as the opportunity to work from home or to diversify the livelihood portfolio, were also crucial, with the trade representing different livelihood strategies for different households. When viewed within the context of rising unemployment and HIV/AIDS these findings assume greater significance. While the trades were complex and growth limited, livelihood benefits could be improved on a sustainable basis if the sector was given the attention and support it deserves.

This thesis examines the historical interaction of the psychoanalyst, Jacques Lacan, the surrealist, Salvador Dali, and the English poet, David Gascoyne. It traces the discursive, and sometimes personal, relationship between these figures which led to a psychoanalytic-based conception of paranoia that impacted on both surrealism and the surrealist-inspired poetry and theory of David Gascoyne. Furthermore it seeks to identify the potential ramifications of this conception of paranoia, and the artistic practice it engendered, for literary, Marxist and psychoanalytic theory.

Whilst the structure of higher plant plasmodesmata was first described by Robards (1963. Desmotubule—a plasmodesmatal substructure. Nature 218, 784), and despite many subsequent intensive investigations, there is still much that remains unclear relating to their ultrastructure and functioning in higher plants. We have examined chemically fixed plant material, and suggest that the conformational changes seen in plasmodesmatal substructure, particularly the deposition of electron-dense extra-plasmodesmal material, is linked to either manipulation of the hormonal balance (as in Avocado fruit), or of osmotic potential in leaf blade material. These changes result in the deposition of β 1,3-glucan (callose) at the neck region of these plasmodesmata. This electron-dense material is deposited at the neck region of plasmodesmata, and forms a collar-like structure. The formation of a collar is shown to be coupled with loss of lucence within the cytoplasmic sleeve. The formation of a collar at the plasmodesmatal orifice thus results in encapsulation and closure of the plasmodesmatal orifice. Closure of the orifice coincides with a loss of electron-lucence and a lack of resolution of the desmotubule. These ultrastructural changes are potentially significant and could contribute to, result in, or assist in the down-regulation of cell to cell trafficking via plasmodesmata.

The Russian wheat aphid (Diuraphis noxia) feeds preferentially from the phloem of longitudinal veins of nonresistant wheat leaves. The xenobiotic, 5,6-CFDA was applied to exposed leaf blade mesophyll cells in control and aphid-infested plants. In control plants, the fluorophore moved approximately 5–6cm from the point of application of 5,6-CFDA within 3h of application. The fluorochrome was transported in the sieve tube companion cell complex, including those in the numerous interconnecting transverse veins. Leaf blades on which the Russian wheat aphid had been feeding demonstrated a marked decrease in 5,6-CF transport. Aphids feeding on the leaves formed local sinks and redirected the fluorophore (and presumably associated assimilate) to the aphids’ gut, with little longitudinal translocation of 5,6-CF below inserted stylets or aphid feeding areas. Aniline blue staining revealed massive deposits of wound and reaction callose caused by the aphids, with callose associated with the sieve plates, pore-plasmodesma between the companion cells and their associated sieve tubes, as well as with plasmodesmal aggregates in parenchymatous elements within the vascular bundles. Leaves that had been colonised by aphids but from which the aphids were removed, showed extensive wound callose deposits, which persisted for up to 48h after removal of aphid colonies, suggesting that the damage caused by aphid feeding is a long-term, non-transient event in non-resistant plants.

Research suggests numerous views to account for the influence on practice of teachers’ beliefs. One view states that teachers’ lived experiences shape their beliefs about practice. Another view attributes the influence to school experiences. This research sets out to gain insight into teachers’ beliefs on the role of extensive reading in second language learning. A case study of 9 teachers from 3 schools in Grahamstown, South Africa selected purposefully and conveniently was utilised. The teachers were viewed to be knowledgeable on this matter by virtue of their profession while the 3 schools were selected to represent a private school, a former Model C and former Department of Education and Training (DET) school. Data was mainly collected by means of semi-structured interviews, which utilised in-depth open-ended questions to yield teachers’ past experiences. The findings revealed the following: all the teachers appeared to believe that extensive reading was invaluable and enhanced language skills. However, white and black teachers differed in terms of their early experiences of reading. Whereas for white teachers early experiences with literacy were encountered in the home, for black teachers the school was where they had their first exposure to literacy. In addition formal training in the form of an ACE (Advanced Certificate in Education) seemed to have influenced black teachers’ beliefs about the subject at hand, whereas the role of teacher education/ training was not as significant for white teachers.

This thesis investigates current sentencing practices relating to the diverse, complex and emotionally laden phenomenon of child sexual abuse. It focuses on relevant legislative provisions, on case law and on an empirical study conducted amongst regional court magistrates. Trends, developments and problems are analysed and possible solutions to the main problems identified are investigated. The thesis concludes with proposed guidelines regarding the sentencing process in child sexual abuse cases. Such guidelines address general and specific principles, the use of victim impact statements, the increased recognition and use of behavioural science in the sentencing phase with regard to both the victim and the offender, and relevant aggravating and mitigating factors. The guidelines are an attempt to give some structure to the current haphazard approach adopted by the courts with regard to harm experienced by the victim. They are also aimed at assisting experts to provide more effective and reliable pre-sentence reports. Further, the thesis attempts to provide clarity concerning the factors that are considered to be aggravating or mitigating in the offence category, child sexual abuse, as well as with regard to the weight that should be attached to them. In addition, recommendations are made for the purpose of possible law reform and further research in relation to the regulation of judicial discretion through the introduction of formal sentencing guidelines, victim impact statements and the accommodation of behavioural science in the sentencing process pertaining to sexual offenders. This proposal is based on current South African sentencing practices as reflected in the consolidation of local judgments scattered over many years in different law reports and, to some extent, on English, Canadian, Australian and American sentencing practices as researched in this study.

The development of small (<300 km²), private game reserves has become a trend, not only in the Eastern Cape Province, but also elsewhere in South Africa as a result of a shift in land use practise from agriculture to ecotourism. The resultant re-introduction of elephants to many of these reserves has lead to management concerns because of the limited research on small reserves regarding their impact on the vegetation. In this study I assessed the space use, habitat selection, diet and impact of two elephant populations on the vegetation in the Eastern Cape Province between February 2004 and March 2005. Home range sizes were calculated using the kernel utilization distribution method. Home range sizes for elephants on Kwandwe were significantly larger during summer than winter (p<0.05). There was no significant difference between the home range sizes of the herds and males within a season and during summer the elephants utilized about 75 % of the reserve and only 54 % during winter. On Shamwari, the herd utilized about 92 % of the reserve during summer and 83 % during winter; while the males utilized 76 % of the reserve. Core areas for both elephant populations shrank from summer to winter and were concentrated around the permanent water sources on each reserve. Habitat selection was assessed using χ² tests and Bonferroni confidence intervals. On Kwandwe, there was a significant difference between observed and expected use of vegetation types (p<0.05) and karroid shrubland was strongly avoided by both herds during summer and winter. The preferred vegetation types of the males ranged from relatively open (short euphorbia thicket, bushclump karroid thicket and karroid shrubland) to completely open (old lands). On Shamwari, subtropical thicket, bontveld and montane grassland were avoided; while primary and secondary acacia thicket, riverine thicket and cultivated lands were preferred. The predominant vegetation type in the home ranges of herds on Kwandwe and Shamwari was subtropical thicket. The diet was assessed by direct observations over two seasons and dietary preferences were calculated. There was a significant difference in the frequency of occurrence of plants in the diet on the two reserves (p<0.05) and no significant effect of time of day or season (p>0.05). Seventeen woody plant species were utilized on Kwandwe and 23 species were utilized on Shamwari. Grass constituted a significantly greater percentage of the diet in summer than winter (p<0.05). Elephants on Kwandwe showed a selective preference for Ozoroa mucronata, Pappea capensis and Acacia karroo; while on Shamwari, A. karroo was selected. Transects were conducted in two different vegetation types on each reserve so as to assess the impact of elephant on the vegetation and damage scores were then calculated from these data. There was no significant effect of vegetation type or elephant density on mean damage scores in Kwandwe (p>0.05). Five hundred and seventy-eight plants were assessed in the subtropical thicket vegetation type and 225 plants were assessed in the savanna-type vegetation, with more than half the trees showing low levels of damage that could not only be attributed to elephants. Mean damage was highest for Portulacaria afra and Pappea capensis in subtropical thicket and for Rhus spp. in the savanna-type vegetation. On shamwari, 408 plants were assessed in subtropical thicket and 215 in the savanna-type vegetation, with more than 70 % of trees showing low levels of damage. There was a significant effect of plant species and elephant density on the mean damage scores in subtropical thicket, with Aloe ferox showing more damage than the other plant species (p<0.01). In the savanna-type vegetation, A. karroo was the most severely damaged. Overall, damage was greater in the thicket vegetation type compared to the more open vegetation type on both reserves.
