Traditional network monitoring techniques suffer from a number of limitations. They are usually designed to solve the most general case, and as a result often fall short of expectation. This project sets out to provide the network administrator with a set of alternative tools to solve specific, but common, problems. It uses the network at Rhodes University as a case study and addresses a number of issues that arise on this network. Four problematic areas are identified within this network: the automatic determination of network topology and layout, the tracking of network growth, the determination of the physical and logical locations of hosts on the network, and the need for intelligent fault reporting systems. These areas are chosen because other network monitoring techniques have failed to adequately address these problems, and because they present problems that are common across a large number of networks. Each area is examined separately and a solution is sought for each of the problems identified. As a result, a set of tools is developed to solve these problems using a number of novel network monitoring techniques. These tools are designed to be as portable as possible so as not to limit their use to the case study network. Their use within Rhodes, as well as their applicability to other situations is discussed. In all cases, any limitations and shortfalls in the approaches that were employed are examined.

This study reports on a social-realist analysis of collaborative curriculum development in a journalism and media studies (JMS) department at a South African university. Archer's social-realist meta-theoretical framework is used to theorise about mechanisms that influence collaborative curriculum development within the context of the JMS Department. The thesis examines the cultural, structural and agential conditions that influenced the process of developing a JMS curriculum that aimed to integrate theory and practice. Bernstein's theories of knowledge recontextualisation and disciplinary knowledge structures are used in the analysis. Bernstein argues that knowledge recontextualisation constitutes a site of struggle. This thesis is an examination of the "struggles" for the epistemic-pedagogic device (Maton's elaboration of Bernstein's epistemic device) during the recontextualisation process that aimed to integrate media studies (MS) and media production (MP) in the JMS curriculum. Traditionally academic work has been an individual endeavour. However, given the growing need to work in disciplinary and inter-disciplinary teams, it is imperative to develop knowledge of the mechanisms that influence such practices. This thesis is a contribution to knowledge of collaborative processes at the level of an academic department in a university. It contributes to knowledge of cultural, structural and agential mechanisms that enable or constrain collaborative curriculum development within a particular kind of context. In addition it contributes to knowledge of the nature of leadership that may be necessary to facilitate productive collaborative relationships and practices in such a context. The curriculum development project reported on in this thesis was initiated in 2003; however, data collection for the study was conducted in 2006 when the curriculum for the fourth year (JMS 4) of the Bachelor of Journalism degree was developed. Since the JMS course prepares students to work as journalists or media workers it is necessary for the curriculum and pedagogy to be oriented both towards the academy and towards the media industries. The aim of the JMS degree is to develop students who will be critically reflexive journalists or media workers. As such the course is both theoretical (MS) and practical (MP). One of the findings of this research project is that the integration of MS and MP is a complex project given that the knowledge of the two disciplines is structured differently. MS is concept-dependent and some aspects of it can be applied to journalism and media practice, while MP is practical and thus context-dependent, though underpinned by theory. A further finding is that both the collaborative work and the integration project required different identity shifts from the lecturers in the JMS Department. Some were more able to make the shifts than others. The thesis shows that the knowledge recontextualisation struggles in the curriculum development processes of the Department of JMS centred around, inter alia, the setting of boundaries between the department and the media and journalism industries, between MS and MP and between MS theory and journalism theory. In addition, existing boundaries between MS and MP lecturers had to be traversed. These boundaries were circumscribed by, amongst other things, unequal power relations emanating from the higher status traditionally accorded to theoretical knowledge by universities, the tensions around the nature of journalism education and training and the differential properties and powers of the various lecturers within the department. The existence of a strong regulative discourse was found to be an important unifying mechanism in a tension-ridden context.

The aim of this study was to find out how praxis is fostered in professional development processes, through the assignment four of the Rhodes University / Swaziland Participatory course in Environmental Education (referred to as the Swaziland course), in the Swaziland context. The research aimed at exploring instances of praxis in assignment four development processes and in implementing the assignment ‘product’ in the field of participants’ practice at their schools. The research is intended to improve practice in professional development in the Swaziland course, and in the SADC region more broadly, although the case study does not assume generalisability. The study employed a naturalistic research methodology, involving the development of an interpretive case study to aid understanding of social phenomena in the natural setting. It is influenced by the belief that knowledge is socially constructed and the assumption that meanings are generated and shared through language. The research methods involved observing interactions in the course processes during tutorials sessions and I compiled a course processes profile. I also analyzed copies of assignment four products of two course participants, and observed them using their assignment ‘products’ in their workplaces. Using this data, I generated two ‘constructions’ of the two course participants’ experiences of praxis-based assignment work in the Swaziland course. I also interviewed two course tutors. Data was analysed with an intention to understand actions and interactions relating to praxis-based assignment work. Two ‘layers’ of data analysis were undertaken, to deepen understanding of the phenomenon studied. Through this research I have learnt that though assignment processes enable praxis basedlearning, there are problems encountered in participants’ field of practice due to power relations and participants articulation of the relationship between theory and practice. These, and other structural factors impinge on reflexive agency in the context of both educational and environmental praxis. The structures in the school system frustrate reflexive agency in environmental teaching and learning, and socio-political and socio-economic structures also constrain environmental praxis, hence false consciousness prevails. Given the above situation I recommend further research into the relationship between environmental and educational praxis in environmental education and further research into reflexive agency in environmental education contexts.

This mixed method, grounded theory study aimed to explore access to Master's level study at Rhodes University, a small, traditional South African university established in 1904, over the ten year period 1999-2008. It also sought to capture the essence of 'postgraduate readiness': the generic (non-certificated) attributes which academics expect graduates to possess in order to undertake Master's degree study. While the majority of students enter Master's level via the formal route (which at Rhodes is an Honours or 4-year bachelor's degree), a significant number are admitted based on the recognition of prior learning (RPL), a practice which is encouraged in South African higher education national policy as a means of widening access and also of acknowledging that learning can take place in ways other than 'formally'. The findings show that while RPL is well defined nationally at the undergraduate level, the concept of RPL at the postgraduate level is vague and largely left to institutional discretion. No national, and few institutional, guidelines are available on which to base the assessment of potential Master's degree students who do not have Honours degrees. Interviews with Deans, supervisors and policy makers at Rhodes indicated that while there is institutional support for admitting alternative access candidates, there is a general perception of deficit compared to those entering the Master's with formal qualifications. However, the statistical findings showed no significant difference in success rates or time taken to completion between students with and without Honours degrees. In addition, comments from supervisors with extensive experience of alternative access students praised the diversity and rich life experience which such students brought to their studies and their peers. The study concludes that an institutional culture characterized by resistance to change, risk and externally imposed regulations at Rhodes has resulted in weak implementation of the University's RPL policy, little marketing or publicizing of alternative access routes to postgraduate study, and low numbers of RPL enrolments at the Master's level. A framework for the assessment of potential Master's candidates - both RPL and formal admissions - for use at Rhodes University and potentially also at other higher education institutions, is proposed in conclusion.

Introduction: Studies reveal differential cognitive effects of alcohol use, with moderate to heavy alcohol having some beneficial effects in older adults, whereas in young adulthood, heavier alcohol use produces deficits. The aim of the research was to investigate the relationship between patterns of alcohol use and the cognitive and symptomatic functioning of university students over one year, and to discern which demographic, clinical and alcohol factors might moderate cognitive outcomes. Method: The sample included undergraduate Psychology students from a South African University, aged 18 to 23 years (n = 86). The sample was divided into two alcohol use groups based on four categories from the Alcohol Use Disorders Identification Test (AUDIT) (Babor et al., 2001), including a lighter drinking group (Safe/Hazardous, n = 74) and a heavier drinking group (Harmful/Dependent, n = 12). The two drinking groups were statistically equivalent for distribution of age, gender, English first language, race groups, history of neurological or psychiatric vulnerability, a measure of initial intelligence/cognitive reserve (Peabody Picture Vocabulary Test: PPVT-4) (Dunn & Dunn, 2007) and for a measure of test-taking validity (Immediate Postconcussion Assessment and Cognitive Test: ImPACT Impulse Control) (p = < 0.05 in all instances). Participants were tested on the computerized ImPACT battery (ImPACT, 2007) at three intervals over an academic year (May, August, October 2012). Repeated measures ANOVAs were used to investigate cognitive and symptomatic differences between the two alcohol use groups, in association with moderating factors. Results: The heavier drinking group revealed: (i) poorer performance on ImPACT Visual Motor Speed, Reaction Time and Cognitive Efficiency Index scores, including less ability to benefit from practice over time; (ii) symptom reports of severe Numbness/Tingling, Balance problems and Dizziness. Deleterious cognitive outcome was exacerbated by longer lifetime duration of alcohol use, passing out monthly, beer or wine drinking, smoking or substance use. Conclusion: Deleterious cognitive and symptomatic effects of heavy alcohol use are in evidence for undergraduate university students implicating current and/or cumulative alcohol induced brain impairment. The results of the study are of concern for optimal academic performance of students at an early stage of university level study, who engage in heavier (Harmful/Dependent) drinking patterns, with negative implications for future career attainment.

Questions of the dominance of cultures of whiteness are pre-imminent issues in historically white South African universities. Even when historically white universities – such as Rhodes University, the site of study for this thesis – have a predominantly black student body post 1994, there are still reports of students experiencing such institutions as alienating and excluding due to the privileging of whiteness. This thesis draws on the significant role played by discourse in how the world is constructed and reconstructed, to better understand how whiteness may continue to be produced and reproduced in everyday interactions at a historically white South African university, and how some students may feel less at home than others within such institutions. The thesis seeks to answer the following research question: what discursive strategies do Rhodes University students use to describe their raced experiences, and what role do these strategies play in either reinforcing and or challenging a culture of whiteness? The thesis engages with and is informed by literature on whiteness as constitutive of both social aspects and phenotypical essence. Drawing primarily from discourse analysis tools, and from interviews with Rhodes University students completed between 2014 and 2015, the thesis argues that whiteness is far from being a zero-sum game of winners and losers. Rather, there are gradations of whiteness where speakers draw upon whatever capital (social, phenotypical or a combination of both) to attain the best possible outcome for themselves. The thesis therefore takes seriously the idea that whiteness is a social construct which can, through socialisation be acquired, lost and, in some cases, decanted partially into other vessels. Whiteness, the thesis argues, is ever incomplete and subject to change as the context changes in order to ensure that it remains associated with privilege, opportunity and power. If whiteness is not limited to white bodies only, as suggested by both the data and literature review, then it must be studied in relation to blackness as well. The interactional, inter-relational and inter-racial construction and use of whiteness both methodologically and conceptually is one of the key contributions to the field of whiteness studies made by this thesis. This open-ended, permanent work in progress approach to whiteness can be the beginning of conversations about race that are not necessarily bounded by phenotype or essence – especially in South Africa, where race and a fixation of rigid social categories continue to be a central part of how South Africans navigate and understand the world around them.

The present study explores Rhodes students' perceptions and attitudes towards HIV/Aids issues. This study focuses on risk behaviour, stigmatisation, social perceptions and voluntary counselling and HIV testing (VCT). There is a lack of research on student attitudes, knowledge and behaviour at Rhodes University. It was therefore deemed pertinent to research this topic in that context. It was envisaged that the study would provide insights to be used in the formulation of improved strategies for HIV/Aids programs and education, ultimately impacting on the exponential increase of the pandemic in the Southern African region. A sample of six hundred and seventy five Rhodes University undergraduates completed a survey and its findings were interpreted in terms of relevant literature. A mixed methods approach using qualitative and quantitative methods was used. A focus group consisting of seven post-graduate students informed the development of the survey along with relevant literature. Four departments from the faculties of Commerce, Humanities, Science and Law were randomly sampled for the survey phase. Statistica was used to calculate descriptive statistics while the chi-square statistic was applied to examine the relationships between the variables. The findings show that the majority of students have high intention levels in planning to use preventative behaviour. However, in practise, this may not be the case. Many students feel that they belong to high or medium risk groups, as opposed to the low-risk groups. In terms of motivation levels, only sixty three percent of students are highly motivated to protect themselves from HIV/Aids and one third of respondents felt that they could not ask their partner to accompany them for an HIV/Aids test. In addition, students who had received VCT were more likely to be positive about the counselling process.

Thesis (M.Com. (Information Systems)) - Rhodes University, 2007.

This research focuses on the extent to which the Rhodes University Academic Skills Programme (ASP), now known as the Academic Development Programme, is able to act as an agent of progressive change within Rhodes University. In so doing it concentrates on the potential of the strategy of integrated academic development for dealing with the academic needs of university students within the context of South Africa as a society in transition. The candidate considers the inability of structuralist educational theory to account for the potential of human agency at the site of formal education. It is shown that structuralist theories provide deterministic and pessimistic accounts of the role of institutions of formal education. In support of this contention this study explores the history of ASP at Rhodes University, demonstrating that significant change in student academic development has already taken place. ASP has contributed to change within the said University through challenging traditional notions of academic development. This thesis suggests that the non-structuralist critical theory of Jurgen Habermas provides a more holistic account of ASP than do structuralist theories of formal education. Through the incorporation of Habermas's theory of communicative action a process of critical integration is explored, showing that a strategy of integrated academic development has the potential to involve all those who have an interest in university education through a process of rational discourse. This potential is strengthened by the fact that many students and staff have expressed an awareness of the need for an integrated academic development strategy. This thesis subsequently explores the possibility of there being a process of democratic and rational discourse which could lead to a progressive integration programme in the Rhodes University Department of Sociology and Industrial Sociology. This thesis stresses the contested nature of the integration process within departments. It is indicated that Habermas's critical theory is able to account for the changes which have taken place in the past and which are presently under way. It is argued that it not possible to predict future outcomes, but that if ASP pursues a process of rational discourse, it will indeed be able to stimulate a critical integrative approach to academic development in the Rhodes University Department of Sociology and Industrial Sociology.

The work of intercultural communication theorists such as Ting-Toomey (1999) and Gudykunst (2003) has informed curriculum design and teaching methodology of the courses developed for teaching isiXhosa for vocational purposes to second language (L2) learners. This seems to be an appropriate theoretical paradigm within multilingual South Africa, where intercultural communication is becoming a daily reality for a growing portion of the population. We make use of this theory to introduce and develop experiential understanding of multilingualism at Rhodes University in various departments and, more generally, on campus.
