- Description: Following the democratic transition in South Africa in the early 1990s the government has implemented a widespread electrification programme, as well as introduced a free basic electricity allowance as a means of poverty alleviation. Yet there are limited longitudinal studies on the impacts of the introduction of electricity on the patterns of household energy use, and even more so in the neglected rural sector. This study reports on the patterns of household energy use in five rural settlements in 1991 and again in 2002. Results indicate a changing pattern of energy use for lighting and powering entertainment appliances, more specifically from dry-cell batteries and paraffin to electricity. Yet for thermal needs, most notably cooking, fuelwood has remained the most widespread fuel, and the amount used per month has not changed, despite increasing scarcity of wood in the local environment. There has been an increase in the proportion of households purchasing fuelwood as opposed to collecting their own. Overall, the mean total number of fuel types used per household has increased, indicating that electricity is simply viewed as an additional energy, rather than an alternative. Yet, electricity accounted for approximately 60% of expenditure on energy sources in 2002, despite the government's policy of a free basic allowance of 5–6 kWh per month. This has implications for energy supply costing, as well as the poverty alleviation dimensions of the whole programme.

- Description: The paper analyses selected aspects of the codeswitching behaviour in a spoken corpus of the English of 326 people, all of them mother-tongue speakers of Xhosa (a local African language in South Africa), and all of whom would see themselves as Xhosa/English bilinguals. The corpus comprises approximately 550,000 transcribed words of spontaneous, relaxed, oral discourse in English between pairs of Xhosaspeaking interlocutors, discussing a wide range of topics. While the usual pattern in bilingual speech is to use the L1 as matrix language and the L2 as embedded language, in this corpus the opposite is the case, as interlocutors were interviewed in English (the L2). The corpus therefore offers a ‘mirror image’, in a sense, of normal codeswitching behaviour. Using Wordsmith (a concordancer programme), all incidences of codeswitching into Xhosa during these conversations were identified and analysed in an effort to reveal underlying patterns. Examination of the amount and nature of codeswitching in the corpus promised to throw some light on the extent to which participants are genuinely bilingual, in terms of their ability to converse comfortably in English.

- Description: Communication is a central feature of human life. The ability to talk is the very feature that distinguishes us from our primate ancestors. Knowing how to use language effectively gives the bearers of this knowledge power over their environment and an upper hand in their dealings with others. Thus, understanding the importance of communication in management is an essential tool for managers who wish to build and develop their organisations and their staff within these organisations. This thesis takes a case study view of manager-staff communication at a South African university. In this study managers and staff members contribute their feelings on current communication practices at this organisation through an online questionnaire and in-depth interviews. In an interpretive paradigm this thesis answers three central questions: 1) what role do managers and staff think communication plays in their working relationships, 2) what do they perceive to be effective and ineffective communication strategies and 3) What strategies can they suggest to enhance effective communication? Through in-depth qualitative research and numerical data analysis this thesis discovers central themes that pertain to the effective flow of communication in this organisation. These themes include: motivation and praise, the role of listening, building relationships, respect, acknowledging others’ languages and cultures, building teams, communicating frequently and using email and technology effectively, as well as keeping notes of meetings and discussions. Challenges to effective communication include not having enough time, suffering from stress, and the challenges of physical space and distance. By paying attention to basic human principles, such as the fact that acknowledging people for a job well done encourages them to perform well in future, this thesis relates the general concepts of communication and management theory to the specific realities and individual, personal experiences of manager-staff communication. In this way it sheds a beam of light on management communication practices and points the way towards an ideal where managers and staff members use communication as a tool of empowerment and understanding.

- Description: The community structure and predation impact of carnivorous macrozooplankton (>2 cm; chaetognaths, medusae, ctenophores and mysids), with particular emphasis on the chaetognaths Eukrohnia hamata and Sagitta gazellae, were investigated during three surveys conducted in late austral summer (April/May) of 2001, 2004 and 2005 in the Polar Frontal Zone in the vicinity of the Prince Edward Islands (46º45’S, 37º50’E), Southern Ocean. The 2001 survey formed part of the Marion Offshore Variability Ecosystem Study (MOVES II), while the 2004 and 2005 surveys formed part of the Dynamics of Eddy Impacts on Marion’s Ecosystem study (DEIMEC III and IV respectively). Macrozooplankton samples were collected using WP-2, RMT-8 and Bongo nets. Results of the hydrographic survey indicated that the region of investigation, the Polar Frontal Zone (PFZ), is an area of high mesoscale variability. During the 2004 survey the Antarctic Polar Front (APF) and the Subantarctic Front (SAF) merged to form an intense frontal feature with subsurface temperature and salinity ranging from 8.5-7.5ºC and 34.15-33.88, respectively. A cyclonic cold core eddy, believed to have been spawned from the APF, was observed during the 2005 survey. Macrozooplankton abundance and biomass ranged from 0 to 43.731 ind. m⁻³, and from 0 to 41.55 mg wwt m⁻³ respectively, during the three surveys. Among the carnivorous macrozooplankton, chaetognaths (Eukrohnia hamata and Sagitta gazellae) were most prominent, contributing up to 85% of the total biomass during all three surveys. Elevated biomass values were found near and within the frontal feature during the 2004 survey, and also along the eddy edge during the 2005 survey. However, hierarchical cluster analysis did not reveal the presence of distinct zooplankton groupings associated with the various water masses encountered during the surveys and this is probably due to the high mesoscale variability in oceanographic conditions that are characteristic of the PFZ. The total average predation impact of the selected carnivorous macrozooplankton during the 2001, 2004 and 2005 surveys accounted for 4.93 ± 6.76%, 0.55 ± 0.51% and 4.88 ± 4.45 of the mesozooplankton standing stock, respectively. S. gazellae had the highest consumption rate in all three surveys, consuming up to 800 g Dwt 1000m⁻³d⁻¹ during the study. Of the two chaetognaths, E. hamata dominated the chaetognath standing stock. The combined abundance and biomass values of E. hamata and S. gazellae ranged from 0 to 43.73 ind. m⁻³ and from 0 to 41.551 mg wwt m⁻³ respectively, during the three surveys. Inter-annual variability in the chaetognath densities was apparent. Highest abundances and biomasses tended to be associated with specific water masses, confirming the existence of a relationship between zooplankton community structure and hydrographic conditions. Generally, about 90% of the chaetognaths contained no food in their guts. S. gazellae consumed a wider variety of prey. Oil droplets occurred in the guts of ≈ 51% of E. hamata. Cannibalism was low in both species, but greater in S. gazellae than E. hamata. During the three surveys, the feeding rate values of E. hamata and S. gazellae went up to 0.48 and 2.099 prey d⁻¹ respectively. S. gazellae also had a greater predation impact on the mesozooplankton standing stock than E. hamata. The mean predation impact of the chaetognaths combined was 0.31 ± 0.291%, 0.52 ± 0.28% and 0.53 ± 0.56% of the mesozooplankton standing stock during the 2001, 2004 and 2005 surveys, respectively. During all three surveys, the majority of individuals (≈ 76%) of the chaetognaths were at stage I maturity, suggesting that during the time of study the chaetognaths were not reproducing. In both species a significant difference (log-linear analysis, p < 0.05) in maturities between the years investigated was observed. In general, there were no differences in lengths and maturities between the different water masses encountered during the surveys. The lengths of E. hamata and S. gazellae ranged from 5 to 24 mm and from 9.4 to 63.6 mm, respectively.

- Description: Photolysis of aqueous solutions of chlorophenols (4-chlorophenol, 2,4-dichlorophenol, 2,4,5-trichlorophenol and pentachlorophenol) in the presence of immobilized non-transition metal phthalocyanine photosensitizers onto Amberlite® is presented. The photosensitizers studied are: Al (AlOCPc) and Zn (ZnOCPc) octacarboxyphthalocyanines; Al (AlPcS4) and Zn (ZnPcS4) tetrasulfophthalocyanines; sulfonated phthalocyanine complexes (containing mixtures of differently substituted derivatives) of Al (AlPcSmix), Zn (ZnPcSmix), Ge (GePcSmix), Si (SiPcSmix) and Sn (SnPcSmix). Photolysis of the chlorophenols resulted mainly in the formation of chlorobenzoquinone derivatives. The complexes showed order of activity towards the transformation of pentachlorophenol as follows: ZnOCPc > SiPcSmix > SnPcSmix > ZnPcSmix > GePcSmix > ZnPcS4 > AlPcSmix > AlOCPc > AlPcS4. The generation of singlet oxygen (1O2) by these immobilized MPc photosensitizers was found to play a major role in their photoactivities towards the transformation of these chlorophenols. Langmuir–Hinshelwood (L–H) kinetic model studies showed that the ZnOCPc, GePcSmix and ZnPcSmix photocatalysis occurred on the catalysts surface. © 2005 Elsevier B.V. All rights reserved.

- Description: Comparative surface electrochemistry and electrocatalytic properties of solid ultrathin monolayer films of metallophthalocyanine (MPc) complexes of cobalt (CoPc), iron (FePc) and manganese (MnPc) self-immobilised, via axial ligation reaction, onto preformed 4-mercaptopyridine self-assembled monolayers (SAMs) on gold electrodes have been described. Surface electrochemical parameters of the modified electrodes showed that these MPc-SAMs are densely packed with flat orientations. The electrochemical, electrocatalytic and stability properties of these MPc complexes follow this order: FePc > MnPc > CoPc. This finding is remarkable as it suggests that the success of using this method of self-assembling of MPc onto gold electrode is largely dependent on the bond distance between the pyridine linker and the central metal of the MPc; the shorter the distance, the faster the co-ordination and the better the electrocatalytic properties towards L-cysteine and thiocyanate. Thus, the superiority of FePc-based SAM over those of the MnPc and CoPc, has been proposed to be the result of the more favorable axial co-ordination properties of FePc with pyridine (i.e. shorter Fe–N(pyridine) bond length.

- Description: Networks of ground-based hydro-meteorological observations are frequently sparse in developing countries and the situation is not improving. Part of the reason is the lack of resources available in countries which have more pressing economic and social issues. However, these are also the very countries where improved estimates of water resource availability are required. While hydrological models have the potential to provide the necessary information, without adequately accurate climate (rainfall, evaporation, etc.) input information, it is extremely difficult to establish models and generate representative water resource availability information. This paper reports on a preliminary analysis of the potential for using satellite derived rainfall data through a comparison with available gauge data for four basins in the southern Africa region. It is clear that the satellite data cannot be used directly in conjunction with historical gauge data. Specifically, the satellite data do not reflect the strong influences on precipitation of topography in some of the basins. However, the prospects of applying relatively straightforward adjustments are promising and further assessments appear to be justified.

It is clear that the satellite data cannot be used directly in conjunction with historical gauge data. Specifically, the satellite data do not reflect the strong influences on precipitation of topography in some of the basins. However, the prospects of applying relatively straightforward adjustments are promising and further assessments appear to be justified.

- Description: This thesis provides a historical account of the emergence of the pharmacy education system in South Africa, and an analysis of the influence of competing interest groups over the pharmacy education curriculum. It provides a critical evaluation of structural-consensus and micro-interpretive approaches to medical and pharmacy education, and sets out a macrointerpretive account of pharmacy education in South Africa. Following Margaret Archer (1979) it analyzes three forms of negotiation between competing interest groups in their efforts to change the pharmacy curriculum; these are political manipulation, external transaction and internal initiation. The thesis argues that whilst the private sector interest group (comprising of retail, wholesale and manufacturing pharmacy) dominated the pharmacy education system until 1994, since then a newly emerged government interest group has begun to compete for educational control. The priorities pursued by this interest group have consistently reflected the objectives set out in the ANC National Health Plan of 1994. The thesis maintains that given its frustration over the non-implementation of the ANC’s health policy objectives, the government interest group is likely to resort to direct political manipulation by passing legislation to alter the content of the current pharmacy curriculum. Such changes would seek to ensure that the syllabus more accurately reflects the ANC Plan’s community health and primary health care objectives. The thesis asserts that such an outcome (of direct political manipulation of the curriculum) is not inevitable, and can be avoided through a process of internally initiated change. It presents the findings of an interpretive case study into how the Rhodes University Community Experience Programme (CEP) influenced final year pharmacy students’ perceptions of the role of the pharmacist. The students’ comments were collected by means of focus group interviews, participant observation and documentary analysis. Whilst the CEP did not successfully transform their concept of the pharmacist’s role, it did succeed in influencing students’ understanding of the notions of community pharmacy and primary health care in line with the government interest group’s health objectives. This thesis concludes that internally initiated change within the pharmacy education system, would be preferable to that imposed through external political manipulation, as such change would be more likely to preserve the independent professional interests of pharmacy academics.

- Description: Introductory remarks: Being a middle-class white South African, I grew up on a diet of predominantly "white" music: rock, pop and Western classical music. I was later introduced to a broader range of musics: blues, jazz, kwaito and traditional Southern African idioms. I found myself particularly attracted to the traditional music of the amaXhosa (especially that of the uhadi bow), possibly due to the fact that this music is hexatonic (that is, based on two major triads whose tonics are one tone apart), a system that bears certain resemblances to the Western tonal idiom. However, much of my musical experience tended to be entrenched in the piano and flute music I played: mostly works by composers who were neatly ensconced in the traditional Western canon. Therefore, despite the broad range of musics with which I was familiarisedduring my tertiary studies, I feel that this early experiential background is the reason I feel most comfortable with Western-influenced music. More recently, I discovered a whole new genre to explore: film music, particularly the work of Elliot Goldenthal, Danny Elfman, John Williams and Philip Glass, whose unique brand of minimalism has extended from the concert hall to thefilm theatre. I am fascinated by the ways in which film scores function. A "main titles" theme usually appears as the film opens, upon which most of the subsequent music is based. This is not a linear process, like a theme and its variations, but a lateral, where the main titles theme is the core that engenders other themes that all share a familial resemblance.

- Description: Introduction: This portfolio consists of musical ideas which I have had for some time now. I have attempted to capture these ideas throughout the portfolio, starting with the smaller works (Brumes et Pluies) and building up to the larger works (James Tiberius, The tide). Brumes et Pluies is minimalistic in style. The interlocking of the two pianos plays an important role in the texture of the piece. The rhythms are repetitive throughout, with only slight variations. Kalahari is more idiomatic, rhythmical and has a main theme which recurs throughout the piece. Melodic fragments are used, sometimes with slight variations. This piece was inspired by the Kalahari desert, with its abundance of life. I enjoy the string quartet because of the homogeneity of sound on the one hand, and the diversity possible by using different techniques and effects on the other. James Tiberius is a work for chamber orchestra. Motifs in the music resemble certain animals. The rhythm is unstable, as is the harmony. There are many melodic fragments throughout. The texture is thin in certain areas (at the beginning) and dense in others (the waltz). The harmony is sometimes unconventional. The Tide was written in response to a memory of a drowning incident I experienced when I was a child. This orchestral piece is strong in form. The opening, for example, is tense and slightly atonal in harmony. The pomposo section tends to utilise most of the orchestra, so the texture is a lot denser here and the harmony is more conventional. I try not to use traditional forms in my composition. Rather, I prefer to compose by re-using and re-introducing ideas as I proceed.

- Description: Truth commissions around the world have given the technique of confession a new public currency and political power. Many works of literature thematising these commissions have also adopted the technique of confession for literary purposes. In this paper I bring Foucault's understanding of the technique of confession, and his discourse on the role of public intellectuals in modernity, to bear upon an examination of Antjie Krog's literary reflection of the work of the Truth and Reconciliation Commission (TRC), entitled Country of My Skull (1998). I look at how this text, and Krog's subsequent public intellectual status as a witness of the TRC, perpetuate the technique of confession without problematising it in ways that Foucault's work would suggest is necessary.

- Description: This study investigated rural livelihoods in two contrasting environments in the upper and lower reaches of the Gariep River: Sehlabathebe in the Lesotho highlands, and the Richtersveld in the Northern Cape, and how these have changed over time. Livelihoods were examined using the Sustainable Livelihoods Framework in conjunction with the household development cycle. This study therefore adopted a multi-scale approach, where a micro-level household analysis was framed within the macro level social, political, environmental, economic and institutional context, while taking into account the role of temporal scale of livelihood change. A multi-scale approach facilitated the identification of the major drivers of change, both exogenous and endogenous. The combination of livelihood strategies pursued differed between the two sites. Households in Sehlabathebe are reliant mainly on arable and garden cultivation, livestock in some households, occasional remittances, use of wild resources, petty trading and reliance on donations. Households in the Richtersveld relied primarily on livestock, wage labour, use of wild resources and State grants or pensions. The livelihood strategies pursued in each site have not changed markedly over time, but rather the relative importance of those strategies was found to have changed. The assets available to households, the livelihood strategies adopted and the changes in these livelihood strategies are influenced by a households stage in the development cycle and differing macro-level factors. Drivers of change operate at multiple spatial and temporal scales, and are often complex and interrelated. The major drivers of livelihood change were identified as macro-economic, demographic, institutional and social and climatic. This study highlights the importance of using historical analysis in the study of livelihoods, as well as the complexity and diversity of rural livelihoods. Ecosystem goods and services were found to play a fundamental role in rural livelihoods and are influenced by institutional factors. Rural households are heavily reliant on the formal economy, and macro-economic changes have had a significant impact on livelihoods. This is highlighted by how the drastic decline in migrant labour opportunities for households in Sehlabathebe has negatively affected them. Vulnerability was shown to be a result of external shocks and trends, such as institutional transformation, a decline in employment opportunities, theft and climatic variation; and differed between the two sites. The role of institutional breakdown was shown to be a major factor influencing rural livelihoods, and this is related to broader economic and political changes. This study contributes to the growing literature on rural livelihoods by allowing for an appreciation of how differing environments and contextual factors influence livelihood strategies adopted, and which different factors are driving change.

- Description: During the second half of the nineteenth century, the Berlin Mission Society made strenuous efforts to convert the rulers of the people in whose areas they worked in the Northern Transvaal. In this they were largely unsuccessful. This raises questions about what forces influenced success and failure, and how the missionaries interpreted this. In this article, we interrogate the Berlin Missions Society’s accounts of the life and death of August Makhahane, a ruler of the Vhavenda who converted to Christianity, against the background of the accounts dealing with Matsiokwane Leboho, a ruler of the Bahananwa who did not convert. Through such a comparison, we aim at exploring the contrasted ways in which the Berlin missionaries reported about the two rulers.

- Description: The new science and technology framework has challenged higher education institutions in South Africa to create research partnerships with industry, to contribute to growing a national system of innovation. Through detailed case studies, this monograph explores how one new organisational form typical of the knowledge society, the network, is currently being created in practice, in all its complex and contingent reality, in three high technology fields. It is the third volume in the Working Partnerships: Higher Education, Industry and Innovation series. The case studies show that knowledge networks are primarily shaped by the competitive dynamics of the industrial sub-sector within which partner enterprises operate, intersecting with the levels of scientific and managerial expertise within higher education partner institutions, and facilitated by government policy steering mechanisms and intermediary partners. The intersection of interests gives all partners a stake in the research project at the heart of the knowledge network, and builds the levels of trust required to succeed. The analysis highlights some of the possibilities and constraints evident in the current policy context, suggesting that state attempts to steer the system need to be more nuanced and targeted, informed by the specificity of sectoral dynamics, and it suggests that universities need to identify their own strategic solutions to develop a flexible and adaptive institutional approach to networks.

Critical media literacy: a design for the future

- Description: [From OPENSPACE Editor Alice Kanengoni's editorial]: Professor Jeanne Prinsloo notes in her article that "In fact, it has been argued that the significance of the media in people’s lives has increased to the extent that it has been described as their primary curriculum, thereby recasting formal education as the secondary curriculum." This therefore requires an incestment in media literacy; people's ability to to understand the world around them, as represented in the media. Thus, Professor Prinsloo argues for critical media literacy, citing the role that the media played in fuelling the genocide in Rwanda, as an illustrative case in point. She states that "While we can not attribute all blame in the Rwandan scenario to the radio use, it is clear that the media mattered." She indicates that "media representations and engagements play a significant role in the way we understand the world, its people and events, and ourselves therein." As such, societies should invest in building a critical citizenry that can read and deconstruct the various ideologies that are often carries in and through the media.

- Description: [From OPENSPACE Editor Alice Kanengoni's editorial]: Professor Jeanne Prinsloo notes in her article that "In fact, it has been argued that the significance of the media in people’s lives has increased to the extent that it has been described as their primary curriculum, thereby recasting formal education as the secondary curriculum." This therefore requires an incestment in media literacy; people's ability to to understand the world around them, as represented in the media. Thus, Professor Prinsloo argues for critical media literacy, citing the role that the media played in fuelling the genocide in Rwanda, as an illustrative case in point. She states that "While we can not attribute all blame in the Rwandan scenario to the radio use, it is clear that the media mattered." She indicates that "media representations and engagements play a significant role in the way we understand the world, its people and events, and ourselves therein." As such, societies should invest in building a critical citizenry that can read and deconstruct the various ideologies that are often carries in and through the media.
