- Description: Calibration in radio interferometry describes the process of estimating and correcting for instrumental errors from data. Direction-Dependent (DD) calibration entails correcting for corruptions which vary across the sky. For small field of view observations, DD corruptions can be ignored but for wide fild observations, it is crucial to account for them. Traditional maximum likelihood calibration is not necessarily efficient in low signal-to-noise ratio (SNR) scenarios and this can lead to ovefitting. This can bias continuum subtraction and hence, restrict the spectral line studies. Since DD effects are expected to vary smoothly across the sky, the gains can be parametrised as a smooth function of the sky coordinates. Hence, we implement a solver where the atmosphere is modelled using a time-variant 2-dimensional phase screen with an arbitrary known frequency dependence. We assume arbitrary linear basis functions for the gains over the phase screen. The implemented solver is ptimised using the diagonal approximation of the Hessian as shown in previous studies. We present a few simulations to illustrate the performance of the solver.

- Description: This research explored whether there is any evidence of reporting of organisational resilience within the integrated reports of a large state-owned enterprise. The organisation chosen for the research was Eskom. The integrated annual reports of Eskom for 2016, 2017 and 2018 were examined. Direct and indirect evidence of organisational resilience was sought within the organisations integrated reports. The direct reporting of organisational resilience was located by using a PDF word search. A thematic content analysis was used to perform the search for indirect reporting of organisational resilience. Three main themes to represent organisational resilience that were identified beforehand were used to identify the indirect reporting of organisational resilience. Namely, transformability, adaptability and persistence. Sub themes of general and specified resilience were also identified during the research process. The literature review discusses the themes in detail, and also introduces communication and integrated reporting. Evidence of both direct and indirect organisational resilience was identified in all three years studied. Evidence of all the main themes and sub themes was found within the indirect reporting of organisational resilience. The main limitation of the study is that although evidence of reporting of organisational resilience was found, this evidence does not provide any indications of the level of organisational resilience within Eskom. A number of recommendations to Eskom management are made at the end of the research. What is interesting is that integrated reports are not designed to report on organisational resilience. However, the research showed clear evidence of reporting of organisational resilience within all three years researched. Potentially indicating that the integrated annual reports are a useful method of sharing information regarding organisational resilience with stakeholders. An additional benefit is that communication with stakeholders is simultaneously contributing to the enhancement of the organisations resilience.

- Description: The main objective of this study was to question and investigate the primacy of illicit financial flows (IFFs) in developing countries, specifically focused on two countries namely China and South Africa. Africa is estimated to have lost approximately $1 trillion to IFFs over the last 50 years, which exceeds the financial assistance that these nations needed over the same period. For years. Africa has been the feeding ground for exploitation and resource plunder, and the narrative has always been Africa is underdeveloped because of this crime. Although this statement holds true in most African countries, what this paper seeks to do is to question whether capital flight, IFFs and more specifically tax evasion and tax haven activity are the reason for the deterioration of African economies or are IFFs perpetuated by economies with unsustainable growth paths. IFFs are an important factor when it comes to obstacles of economic growth. But are they the cause or effect? A very strong case can be made that they are the latter however, it is beyond the scope of this article to resolve this question. Its purpose is merely to assert that the question is a valid one and that presuming the answer could divert attention from the real question of economic development. This study contextualized the way in which IFFs are currently viewed in the world economic system according to the two approaches to development finance, and discussed modern monetary theory as an extension off these theories. Due to the nature of the study, the methodology employed is a case study approach between China and South Africa by means of extensive numerical and document analysis. Upon conducting this analysis on the primacy of illicit financial flows in developing countries there was difficulty in measuring IFFs. The reason for this is because IFFs have a range of estimates so it was very difficult to produce precise and accurate results. The key findings of this paper were that there seems to be some kind of parallel between developing countries with large volumes of illicit financial outflows, and a dependency these countries have on external debt. This means it seems that weak economies, that are highly dependent on external debt and have large amounts of this debt, seem to have the largest volumes of illicit financial outflows. Weak regulation, high levels of debt and liberalised trade markets seem to be contributing factors to the degree to which companies evade taxes and partake in tax haven activity in these regions. Another key finding was that in 2012, despite China being ranked number one in the the countries which have the largest amounts of outflows on average, it still managed to achieve large amounts growth in the last 20 years. Indicating that there is some form of indication that IFFs could be viewed as symptomatic of weak financial systems and weak economies, instead of IFFs being the core of the problem.

- Description: The main aim of this research is to examine the hip hop scene in Grahamstown, Eastern Cape and whether hip hop can serve as a significant platform to discuss women’s lived experiences. This study also places focus on how female rappers construct their rap personas, as well as how they are perceived by their male counterparts. In order to understand the multifaceted viewpoints, it was necessary to interview both male and female hip hop artists. Eight interviews were conducted with eight young black rappers who are actively involved in the Grahamstown hip hop scene. It was found that hip hop, like any other art form, is a significant platform for women to express themselves, however gender constraints limit who is willing to listen to and promote their music. Male rappers advocate for women to talk about their stories, yet are more unlikely to listen because it does not relate to their struggles. In addition, there seem to be four specific tropes that female rappers choose to construct their identities from. Female rappers tend to create their personas around: Queen Mother, Fly Sista, Bitch with Attitude, and Lesbian. However, these categories are fluid and it was found that women navigate these categories depending on their audience and message they want to convey at a particular moment. Lastly, there is a split between Grahamstown West (Rhodes University) and Grahamstown East (township). University students are unlikely to perform in the township, and township residents rarely perform at organised events in Grahamstown West. In addition, Rhodes University students are more likely to feature on the university run radio station, rather than Radio Grahamstown, the local community radio.

- Description: Alien invasive species have the ability to transform or alter environments, often causing severe ecological and/or economic impacts. Marine bioinvasions are occurring globally and are most often facilitated (intentially and accidently) through anthropogenic activities including the building of inter-oceanic canals, shipping and commerce. The Mediterranean mussel, Mytilus galloprovincialis, is a globally successful marine alien invasive species which was first recorded on the west coast of South Africa in the late 1970s and the south coast in 1988. This species is thought to have reached the Knysna Estuary in the early 2000s and has colonised all man-made hard substrata in the embayment of the estuary. Although there are studies on recruitment of M. galloprovincialis on the rocky intertidal coasts of South Africa, there is little information on recruitment of this species in more sheltered estuarine environments. This study aimed to determine recruitment levels of M. galloprovincialis and other bivalves within the Knysna estuarine embayment. To determine monthly recruitment, 10 recruit collectors/pads (plastic pot scourers) were placed at three separate locations within the embayment of the estuary for a week on a monthly basis for 20 months. In addition, recruitment of M. galloprovincialis over spring and neap tides and different lunar phases was also determined at two sites within the Knysna estuarine embayment during the main reproductive season in 2018. The pads were deployed three days before a neap/spring tide and then collected three days after the respective tide. Finally, to look at how rapidly M. galloprovincialis and other macroinvertebrates (when M. galloprovincialis was excluded) would re-colonise free space, 18 plots (15x15 cm), consisting of three treatments including a control (A,B and C), were cleared in M. galloprovincialis mussel beds and then photographed monthly for 12 months. Four bivalve taxa (Mytilus galloprovincialis, Perna perna, Ostreidae, unidentified mytilid) were recorded during the monthly study. Recruitment levels for all bivalves differed significantly (P < 0.001) between months and sites, with peak recruitment occurring from late spring to early autumn (November – March). Mytilus galloprovincialis recruitment levels were greater than other bivalves and were up to 4.5x greater than other taxa. Recruitment also varied between years possibly owing to differences in larval supply and/or environmental factors. Spatial variation in bivalve recruitment was observed throughout the study. The greatest recruitment was at the site (Thesen Island Wharf) closer to the entrance of the embayment. By contrast at the site (Railway Bridge) furthest from the entrance lower recruitment was found. This difference is possibly due to differences in hydrodynamics or other biological and/or environmental factors. A preliminary tidal study found that M. galloprovincialis had significantly higher (P < 0.001) recruitment levels over spring tides than neap tides at Thesen Island Wharf, whereas recruitment at the Railway Bridge on spring and neap tides was not significantly different. In the study undertaken in the reproductive season only, recruitment levels were high over a two week period during both a spring and neap tide, suggesting that factors other than lunar phase and the state of tide are more important in determining the timing and intensity of recruitment. The clearance plots created and photographed over a 12 month period showed that M. galloprovincialis rapidly occupied free space (eight months to virtually cover all free space) by encroachment from the adjacent mussel bed. Limpets and barnacles were only able to colonise cleared space when M. galloprovincialis was excluded, suggesting that the mussel has the ability to outcompete indigenous macrofauna for space. The high recruitment levels of M. galloprovincialis compared to other indigenous bivalves, as well as its ability to occupy space rapidly are traits that must contribute to the success of the invasion of this species within the Knysna estuarine embayment, particulary within Thesen Islands Marina and Thesen Island Wharf.

- Description: One of the biggest limiting factors in marine finfish aquaculture is the low survival rate of early-stage larvae. Most mortalities can be ascribed to the poor nutritional value of live feeds, sibling cannibalism, and various stressors that result in swim bladder hyperinflation and/or starvation during the larval stage. Research results vary on the best timing for the introduction of artificial feed for good survival and growth rate in dusky kob larvae. The main objective of this experiment was to improve survival and growth rate. The experiment focused on a new feeding regime that sought to wean larvae onto an artificial diet earlier than the current Argyrosomus japonicus standard (weaning commenced at 16 days after hatch (DAH) versus 20 days after hatch), based on findings and recommendations made by Musson & Kaiser (2014). Three trials were conducted, each with five replicates of the two treatments, namely the new feeding regime and the standard feeding regime in a fully randomised design. Samples from each tank were collected every two days for the duration of the trial. Morphometric measurements (standard length; body depth; eye diameter) obtained from these sample larvae were used to compare growth rates between treatments. The ratio of BD:SL was used to assess larval condition throughout each trial. Tank survival rates were calculated on the last day of each trial.The study indicated that in mean water temperatures ranging from 24.3 – 25.2 °C, dusky kob larvae can be weaned onto an artificial pellet diet from 16 - 21 DAH without any negative effects on growth, condition and survival. Results from the highest mean temperatures of Trial 2 show a better mean condition in the treatment group during the weaning period (p < 0.05). In Trial 3, with its lower mean water temperatures of 23.2 °C, larvae in both treatments showed stunted absolute growth rates of all biometrics when compared to results from the higher mean temperatures of Trials 1 and 2. During the first 6 days of Trial 3 larvae were in relatively poor condition, BD:SL ≤ 0.30. During this same period in Trials 1 and 2, mean BD:SL ≥ 0.31, suggesting that a BD:SL ratio of ≤ 0.30 in non-weaned dusky kob larvae is an indicator of a degree of starvation. A future study on the morphology and histology of the larval gastrointestinal tract, specifically the liver and intestines, and how this early weaning regime affects their ontogeny under differing temperature conditions this needed to investigate the validity of these initial data on dusky kob larvae condition.

- Description: Purpose – Companies operating in the South African retail industry have been experiencing a high staff turnover, reported to be standing at 36% (Kelly, 2016). The Edcon Retail Group and Taste Holdings have already indicated their strategic focus on staff turnover reduction in order to achieve their business objectives (Crotty, 2017; Laing, 2017). This research study explained the relationship between the three leadership styles of the Full Range Leadership Theory (FRLT) model developed by Bass and Avolio and three types of commitments from the three component model of Meyer and Allen. The research study was interested in the leadership style that contributes the most to commitment. The effective leadership style may be developed to improve the level of employee commitment in the South African Retail industry. Methodology – The research study used the total population of 300 subordinate employees from four stores of a retail company in the Rustenburg region in the North-West Province of South Africa. The Multifactor Leadership Questionnaire (MLQ 5X) instrument was adopted for leadership questionnaire data collection, the three-component model of commitment was adopted for data collection of the commitment questionnaire. Pearson Correlations quantitative data analysis was adopted to explain the relationship of the independent and dependent variables. Multiple Regression quantitative data analysis was adopted to test the strength of the leadership styles on commitment. Findings – The statistical analysis results of Pearson Correlations found weak but significant positive relationship between Transactional leadership style and both Normative and Continuance commitment. A weak but significant positive relationship was found between Transformational leadership style and Normative commitment. A weak but significant positive relationship was found between Passive/Avoidant leadership and continuance commitment. Transformational leadership style showed more strength in contribution to commitment, followed by the Transactional leadership style. Significant – This research study will expand the existing but limited leadership style and commitment body of knowledge in the South African retail industry. The South African retail companies will be able to develop the preferred leadership style by its employees and develop this leadership style in their managers to improve the commitment of their employees.

- Description: Purpose – Companies operating in the South African retail industry have been experiencing a high staff turnover, reported to be standing at 36% (Kelly, 2016). The Edcon Retail Group and Taste Holdings have already indicated their strategic focus on staff turnover reduction in order to achieve their business objectives (Crotty, 2017; Laing, 2017). This research study explained the relationship between the three leadership styles of the Full Range Leadership Theory (FRLT) model developed by Bass and Avolio and three types of commitments from the three component model of Meyer and Allen. The research study was interested in the leadership style that contributes the most to commitment. The effective leadership style may be developed to improve the level of employee commitment in the South African Retail industry. Methodology – The research study used the total population of 300 subordinate employees from four stores of a retail company in the Rustenburg region in the North-West Province of South Africa. The Multifactor Leadership Questionnaire (MLQ 5X) instrument was adopted for leadership questionnaire data collection, the three-component model of commitment was adopted for data collection of the commitment questionnaire. Pearson Correlations quantitative data analysis was adopted to explain the relationship of the independent and dependent variables. Multiple Regression quantitative data analysis was adopted to test the strength of the leadership styles on commitment. Findings – The statistical analysis results of Pearson Correlations found weak but significant positive relationship between Transactional leadership style and both Normative and Continuance commitment. A weak but significant positive relationship was found between Transformational leadership style and Normative commitment. A weak but significant positive relationship was found between Passive/Avoidant leadership and continuance commitment. Transformational leadership style showed more strength in contribution to commitment, followed by the Transactional leadership style. Significant – This research study will expand the existing but limited leadership style and commitment body of knowledge in the South African retail industry. The South African retail companies will be able to develop the preferred leadership style by its employees and develop this leadership style in their managers to improve the commitment of their employees.

- Description: This thesis seeks to understand the cultural and social experiences of black Zimbabwean students, as foreign students, at Rhodes University in Grahamstown, South Africa. It examines the ways in which black Zimbabwean students negotiate the cultural, social and institutional milieu of Rhodes University, which is a former white English-medium university. In doing so, the thesis draws upon Interface theory because, once entering the university space, these students interpret the space and simultaneously negotiate their way in and through this space along cultural and social interfaces. The fieldwork for the thesis involved in-depth interviews with eighteen black Zimbabwean students at the university, stratified in terms of both gender and year of study. A focus on gender facilitated an understanding of possible differences between male and female Zimbabwean students in terms of social and cultural experiences; while a consideration of year of study allowed for an examination of possible shifts in negotiation over time, from first year to Master’s level. The findings demonstrate a range of challenges faced by black Zimbabwean students while at Rhodes University, some of which arise from differences between Zimbabwean and South African society. At the same time, there are considerable differences amongst black Zimbabwean students in relation to the manner in which negotiation took place. While some students negotiate the space through active socialising and assimilating into the local world and lives of South African students as well as the university’s institutional culture, other students negotiate the space through isolation and alienation. Overall, with regard to adjusting to the world of Rhodes and South Africa, students pursued different routes which, in the end, made sense to them.

Challenging Biblical boundaries: Jeanette Winterson’s postmodern feminist subversion of Biblical discourse in Oranges are not the only fruit (1985) and Boating for beginners (1985)

- Description: This thesis investigates the subversion of Biblical discourse in Jeanette Winterson’s first two novels, Oranges are Not the Only Fruit and Boating for Beginners. By rewriting Biblical stories Winterson challenges traditional Western religious discourses and their rules for heteronormative social and sexual behaviours and desires. Winterson’s texts respond to the patriarchal nature of socially pervasive texts, such as the Bible, by encouraging her readers to regard these texts with suspicion, thus highlighting what can be seen as a ‘postmodern concern’ with the notion of ‘truth’. Chapter One of this thesis comprises a discussion of Biblical boundaries. These boundaries, I argue, are a process of historical oppression which serves to subjugate and control women, a practice inherent in the Bible and modern society. The Biblical boundaries within which women are expected to live, are carefully portrayed in Oranges and then comically and blasphemously mocked in Boating. Chapter One also argues that Winterson’s sexuality plays an important role in the understanding of her texts, despite her desire for her sexuality to remain ‘outside’ her writing. Chapter Two of this thesis, examines the mix of fact and fiction in Oranges, in order to create a new genre: fictional memoir. The chapter introduces the concept of the ‘autobiographical pact’ and the textual agreement which Winterson creates with her readers. In this chapter, I examine Winterson’s powerful subversion of Biblical discourse, through her narration of Jeanette’s ‘coming out’ within a Biblical framework. Chapter Three of this thesis examines Winterson’s second book, Boating, and the serious elements of this comic book. This chapter studies the various postmodern narrative techniques used in Boating in order to subvert Biblical and historical discourse. Chapter Three highlights Winterson’s postmodern concern with the construction of history as ‘truth’. Finally, Chapter Four compares Oranges and Boating, showing the texts as differing, yet equally relevant textual counterparts. This chapter examines the anti-feminine characters in both texts and Winterson’s ability to align her reader with a feminist or lesbian viewpoint. This thesis argues that Winterson’s first two texts deliberately challenge Biblical discourse in favour of a postmodern feminist viewpoint.

- Description: “Forgetting Ntaba kaNdoda”: Reciting Performative Memories at the Ntaba kaNdoda Monument serves as a theoretical examination of the Ntaba kaNdoda Monument as a commemorative marker. My mini-thesis unpacks the notions of memory and performative memorialisation at a nationalist memorial in the former Ciskei by examining the concepts of place, memory and memorialisation, which are theoretically integral in my professional practice. This research initiates an investigation into the effects on memory in a situation where the construction of the Monument disrupted an efficacious memorialisation by the communities of Ntaba kaNdoda. In my accompanying MFA exhibition Forgetting Ntaba kaNdoda, I explore notions of place, memory and memorialisation through installations of a variety of photographic processes that are based on what I call ‘de-monumental’ and performative monuments (Widrich2014). The written component of my MFA submission relates directly to my professional art practice, developing and situating it within a relevant context. In my mini-thesis, I consider photographers working with notions of place, memory and memorialisation. Lebohang Kganye and Nassim Rouchiche’s works retrace and recall past memory in the present, while David Goldblatt and Cedric Nunn, who have photographed the Ntaba kaNdoda Monument, point the viewer to the values and histories of the communities most affected by colonialism and apartheid. These photographers’ works operate as mnemonic devices that seek to translate a lived experience at a particular place. I use Widrich’s (2009; 2014) conception of “performative monuments”, Lippard’s (1997) “sense of place” and Nora’s (1989) “lieu[x] de mémoire” and “milieux de mémoire” in approaching my professional art practice and my research into the Ntaba kaNdoda memorial. Using these entwining nodes of theories in formulating what I term ‘demonumentalisation’ in my photography practice at the Ntaba kaNdoda Monument, my photography functions as both performative memorialisation and de-monumentalisation. Remembrance, using photography as a vehicle to represent this notion at Ntaba kaNdoda, transcends the materiality of the Monument. My exhibition, in conjunction with this mini-thesis, therefore reframes and reconfigures theNtaba kaNdoda Monument as a multiplex memory place.

- Description: The deduction of damages and the associated legal costs must satisfy the requirements of the preamble to section 11 and section 11(a) of the Income Tax Act 58 of 1962, read with section 23(g) (referred to as the general deduction formula). This research examined under what circumstances a payer of damages and the associated legal costs would be able to claim a deduction from taxable income. This research also considered whether or not the issue of fault is a relevant consideration in determining whether a deduction should be allowed. In some cases the courts appear to have disallowed a deduction if the expenditure or loss was incurred as a result of a negligent or unlawful act. In other instances the courts have allowed the deduction of damages despite the expenditure or loss having been incurred as a result of a negligent or unlawful act. The research concludes that negligence is not a relevant consideration in the deduction of damages and the associated legal costs. In order to secure a claim for damages the taxpayer must prove that the expenditure was incurred in the production of income and it was expended for the purposes of trade. Associated legal costs are only deductible if the damages satisfy the requirements of section 11(c).

- Description: [Message from the President of IEASA, Dr Roshen Kishun]: The fourth edition of Study South Africa; Guide to South African Tertiary Education coincides with a momentous event in the history of South Africa. It is the 10th anniversary of the democracy after the 1994 elections that ended apartheid. It is time to celebrate the achievements, the development strides, and the reintegration of South Africa into the world community. The International Education Association of South Africa (IEASA) welcomes the new Minister of Education, Ms Naledi Pandor, elected to the Cabinet after the April 2004 elections. We wish her well in her new and demanding portfolio. We are confident that the Minister will support the tertiary education sector to develop linkages between international education, skilled migration and the transition to knowledge economies. While we believe that a free and democratic country may be the most powerful attraction for international students wishing to study in South Africa there are other reasons. South Africa is rated as a technological powerhouse on the African continent. Comparatively South Africa’s educational infrastructure can be compared with the best in the world. Its research sector is by far the strongest in Africa. The country has adopted English as one of its official languages and it is the main medium of instruction in the tertiary education sector. A significant factor which makes South African qualifications attractive is the relatively lower cost of study. Study in South Africa offers the best of both worlds to international students, combining the experience of living in Africa with the opportunity to obtain quality education at a fraction of the cost. In the ten years since 1994, the opening-up of the tertiary education sector in South Africa is evidenced by the dramatic increase of international students studying in the South African public education sector from about 13 000 to more than 47 000 in 2002. While the headcount numbers include distance education students, it is possible that South Africa is currently the leading host country for international students in Africa. An IDP report predicts that by 2025 almost eight million students will be educated trans-nationally. The growth in international student numbers presents South Africa with some exciting challenges in the global context. South Africa is expected to become one of the top nations in the world hosting international students in the next ten yean. Study South Africa is published in the middle of one of the most intense periods of change when the South African education system is being restructured to eliminate duplications created under the apartheid system. The number of public institutions is being reduced from 36 to 23 through mergers and incorporations. The binary divide that existed in the public higher education system pre- 2002, where there were 21 universities and 15 technikons is blurred by the creation of the universities of technology. In spite of the massive transformation, the South African higher education sector has much to offer in the form of quality education, advanced research facilities and internationally recognized qualifications. The information provided in this Guide introduces the individual institutions, their academic offerings, support services provided and other relevant details needed to make a choice of study destination Study South Africa is also a useful tool in the development of a strategy to market South African higher education into the competitive world of international education. The decision by IEASA to develop a marketing strategy is not only a reaction to global higher education pressures, but is also an acknowledgement of South Africa’s return to the global higher education community and in identified geographical areas. IEASA realised that past isolation can only be overturned by conscious new strategies. This 'marketing initiative’ meant that the presence of South Africa was highly visible at some of the leading forums dealing with international education in the world. Study South Africa is undertaken by IEASA in association with the South African Vice-Chancellors Association (SAUVCA) and the Committee of Technikon Principals (CTP). These organizations themselves are set to merge in the near future. We appreciate the support of the Council on Higher Education (CHE), the South African Qualifications Authority (SAQA), Unitech (Higher Education professional body for marketing, communication and development), and Professor T Mthembu. We are most grarefril to Karen MacGregor, our specialist writer, who compiled the excellent articles in this publication on achievements during the ten years of transformation. I wish to take this opportunity of thanking all those who made contributions for their support and all the tertiary education institutions in the public education sector for their participation. We are grateful to the Department of Foreign Affairs for the distribution of the Guide abroad and to members of the IEASA publications committee for their input. We appreciate the support of Artworks Publishing for working under pressure to meet publications deadline. Special thanks are due to Zandile Wanda for the work in coordinating the response from the tertiary education sector and to Alexandra van Essche for compiling and producing the Guide. Without their efforts it would not have been possible to publish the Guide. , 4th Edition

In spite of the massive transformation, the South African higher education sector has much to offer in the form of quality education, advanced research facilities and internationally recognized qualifications. The information provided in this Guide introduces the individual institutions, their academic offerings, support services provided and other relevant details needed to make a choice of study destination Study South Africa is also a useful tool in the development of a strategy to market South African higher education into the competitive world of international education. The decision by IEASA to develop a marketing strategy is not only a reaction to global higher education pressures, but is also an acknowledgement of South Africa’s return to the global higher education community and in identified geographical areas. IEASA realised that past isolation can only be overturned by conscious new strategies. This 'marketing initiative’ meant that the presence of South Africa was highly visible at some of the leading forums dealing with international education in the world. Study South Africa is undertaken by IEASA in association with the South African Vice-Chancellors Association (SAUVCA) and the Committee of Technikon Principals (CTP). These organizations themselves are set to merge in the near future. We appreciate the support of the Council on Higher Education (CHE), the South African Qualifications Authority (SAQA), Unitech (Higher Education professional body for marketing, communication and development), and Professor T Mthembu. We are most grarefril to Karen MacGregor, our specialist writer, who compiled the excellent articles in this publication on achievements during the ten years of transformation. I wish to take this opportunity of thanking all those who made contributions for their support and all the tertiary education institutions in the public education sector for their participation. We are grateful to the Department of Foreign Affairs for the distribution of the Guide abroad and to members of the IEASA publications committee for their input. We appreciate the support of Artworks Publishing for working under pressure to meet publications deadline. Special thanks are due to Zandile Wanda for the work in coordinating the response from the tertiary education sector and to Alexandra van Essche for compiling and producing the Guide. Without their efforts it would not have been possible to publish the Guide. , 4th Edition

The development of a scale to measure sexual orientation and an examination of its psychometric properties

- Description: The purpose of the study was to develop a scale to measure sexual orientation and to examine its psychometric properties. Previous scales were critically examined and compared and the need for a scale which simultaneously measures same and opposite sex responsiveness independently, and accounts for dynamic changes over time, while testing a number of overt and covert dimensions of sexual orientations, was established. A 48-item scale was designed to tap self-reported intensity and frequency of Emotional Attachment, Sexual Fantasy, Sexual Attraction and Sexual Contact towards males and females in the Past, Present and Future. An initial study was conducted with 13 undergraduate university students of both genders, representing a variety of sexual orientations and nationalities, and qualitative feedback was obtained and utilized to make appropriate adjustments and refinements to the scale. The scale was then administered to 133 Rhodes University undergraduate psychology students to obtain quantitative data with regard to its internal structure. The scale was found to have a good internal consistency reliability Cronbach alpha coefficient of 0.8106. Existing sub-scales had lower alpha coefficients. Factor analysis, a form of construct validation, was performed and four factors emerged. These had very good internal consistency reliability alpha coefficients: Sexual Responsiveness to Females (0.9894), Sexual Responsiveness to Males (0.9741), Emotional Attachment to Females (0.8403) and Emotional Attachment to Males (0.8372). These factors were further statistically analysed to ascertain how they relate to one another and to the demographics of gender, age, relational status and sexual orientation identity. Future research will need to assess other forms of reliability and validity and focus on larger and more varied samples.

- Description: This study attempts to present a comparative analysis of the implication of the IMF in Zambia and South Africa in its Reconstruction and Development Programme (RDP). In examining the IMF programme, the study focuses on the Fund's understanding of such economies and its prescriptions for development. It is argued that IMF's familiar orthodoxy will have disastrous consequences for South Africa's poor, disadvantaged and rural communities. Finally, the IMF's market-oriented policy prescriptions are likely to erode democracy and have devastating effects to people-centred development programmes such as the RDP.
