- Description: Literature indicates that tax relief measures for persons with disabilities are important as they align with the principle of equity in the allocation of the tax burden. They are a government intervention that assists in decreasing the financial burden of medical care for persons with disabilities. The right of persons with disabilities to an adequate standard of living is contained in the landmark Convention on the Rights of Persons with Disabilities and Optional Protocol, a treaty of the United Nations, which South Africa ratified in 2007. The objective of the research was to provide a comparative study of tax relief measures for persons with disabilities in South Africa with those of Canada and the Republic of Ireland, with a view to identifying potential areas for improvement in South Africa. The requisite information was primarily collected through an extensive analysis of the tax legislation in the jurisdictions. The research found that tax relief measures for persons with disabilities and their families in South Africa are limited when compared with those of Canada and the Republic of Ireland. The comparative study identifies a number of potential tax relief measures for implementation in South Africa.

- Description: Invasive non-typhoidal Salmonella, caused by the intracellular pathogen Salmonella enterica, has emerged as a major cause of bloodstream infections. It remains a neglected infection responsible for many deaths in Africa, as it fails to receive the level of support that is given to most better known infections. There are currently no vaccines against invasive non-typhoidal Salmonella. First-line antibiotics have been used for treatment, however, the rise in the resistance of the bacteria against these antibiotics has made treatment of invasive salmonellosis into a clinical problem. Therefore, the discovery of new compounds for the development of antibiotic drugs is required. Central metabolic pathways can be a useful source for identifying drug targets and among these is the non-mevalonate pathway, one of the pathways used for the biosynthesis of isoprenoid precursors. The second step of the non-mevalonate pathway involves the NADPH-dependent reduction of 1-deoxy-D-xylulose 5-phosphate (DOXP) into 2-C-methyl-D-erythritol 4-phosphate (MEP). 1-Deoxy-D-xylulose 5-phosphate (DOXP) reductoisomerase plays a vital role in the catalysis of this reaction and requires NADPH and divalent metal cations as co-factors for its activity. In this investigation recombinant DOXP reductoisomerase from Salmonella enterica, Plasmodium falciparum and Mycobacterium tuberculosis were biochemically characterized as potential targets for developing drugs that could be used as treatment of the disease. The expression and nickel-chelate affinity purification of S. enterica DOXP reductoisomerase in a fully functional native state was successfully achieved. However, the expression and purification of P. falciparum DXR and M. tuberculosis DXR was unsuccessful due to the formation of insoluble inclusion bodies. Although alternative purification strategies were explored, including dialysis and slow dilution, these proteins remained insoluble, making their functional analysis not possible. An NADPH-dependent enzyme assay was used to determine the activity of S. enterica DXR. This assay monitors the reduction of DOXP to MEP by measuring the absorbance at 340 nm, which reflects the concentration of NADPH. An alternative assay, resazurin reduction, which monitors the NADPH-dependent reduction of resazurin to resorufin, was explored for detecting enzyme activity. The recombinant S. enterica DOXP reductoisomerase had a specific activity of 0.126 ± 0.0014 μmol/min/mg protein and a Km and Vmax of 881 μM and 0.249 μmol/min/mg respectively. FR900098, a derivative of fosmidomycin, is a well-known inhibitor of DXR, however, the sensitivity of S. enterica DXR towards FR900098 has not yet been reported. The NADPH dependent enzyme and resazurin reduction assays were used to determine whether FR900098 has enzyme inhibitory effects against S. enterica DXR. Upon confirming that FR900098 is able to inhibit S. enterica DXR, FR900098 was used as a control compound in the screening of novel compounds. The S. enterica DXR enzyme was screened for inhibition by the collection of compounds from the Pathogen Box. Compounds that exhibited the desired inhibitory activity, referred to as ‘hits’ were selected for further investigation. These hits were confirmed using the NADPH-dependent enzyme assay, resulting in the identification of two different DXR inhibitor compounds, MMV002816, also known as diethylcarbamazine, and MMV228911. The inhibitory concentration (IC50) values of FR900098, MMV002816 and MMV228911 against S. enterica DXR were 1.038 μM, 2.173 μM and 6.861 μM respectively. The binding mode of these compounds to S. enterica DXR could lead to the discovery of novel druggable sites on the enzyme and stimulate the development of new antibiotics that can be used for treating Salmonella infections.

- Description: Prominent German automotive manufacturers had been tampering with emissions for some time before it became public knowledge in September 2015. It is then that that the term ‘Dieselgate’ was coined in reference to the scandal. As the scandal became public knowledge, manufacturers accused of emissions cheating faced challenges on several fronts, including legal, financial and environmental. While the ‘backlash’ as a result of the scandal was apparent in other countries, it was not as apparent in South Africa. This research paper set out to explore the impact that the Dieselgate scandal had in South Africa in terms of customer equity. Data analysis was undertaken using a two-pronged approach. The first of these was analysis of vehicle sales data using a paired t-test. This was to understand whether sales had seen a decline pre-, as well as post-scandal. The results point to a sales decline, this highlights that Dieselgate was a factor even though other, unexamined factors, were not investigated. The second instrument used was a customer equity questionnaire, this provided insight into the real opinions of consumers in South Africa about the affected brands. The analysis revealed that the affected manufacturers operating in South Africa had seen no negative effects in terms of customer equity. Based on the results, it could be said that market factors, which was not part of the research, play a great role in consumers’ preferences or mindsets. Additionally, manufacturers can operate with a degree of latitude in certain markets. This is based on market factors in a specific market as well as the regulations imposed and enforced in that market. Lastly, customer equity is a complex theory that includes a multitude of converging theories. Based on this fact, it is currently difficult to evaluate customer equity in its entirety in a single paper. A comprehensive model is yet to be developed that can effectively measure customer equity in an all-encompassing way.

- Description: This thesis utilises an interdisciplinary approach to understand the political significance of the experimental poetics used by Claudia Rankine in Citizen: An American Lyric and Koleka Putuma in Collective Amnesia. Rankine and Putuma offer contemporary reflections on what it means to occupy marginalised spaces in society. These artists experiment with formal and conventional aspects of literature to explore and create new definitions of what it means to be Black in society. Their works and techniques allow for thinking outside of dominant ideologies of race and posit alternative Black identities that are not found within canonical theory on Blackness. This project reflects on existing theories of Black subjectivity as evident in Frantz Fanon’s Black Skin, White Masks and Aimé Césaire’s Notebook on the Return to My Native Land. While these theorists did not reject the role of Black women in Western civilisation, they should be read as a moment in a series of counter-discourse to the Black Other rather than the finite canon of Black subjectivity. The emergence of Rankine and Putuma’s experimental poetics works to disrupt the conflation of the Black subject with the Black heteronormative male. Using Michelle M. Wright’s Physics of Blackness as its primary theoretical framework, this project advocates alternative and disruptive readings of Blackness that potentially shift Blackness away from its conflation with nationalism, masculinity and heteronormativity. This thesis uses a dialogical approach between political theory and literature which allows for Citizen and Collective Amnesia to be read as acts of resistance to epistemological erasure and as articulations of the politics relevant to the poets’ lived experiences. Both the United States and South Africa have a history of institutionalised racial segregation, which allows Rankine and Putuma to be read in relation to one another. Where the Civil Rights movement and the anti-apartheid struggle were both foregrounded as male-lead liberation movements contemporary social movements including #blacklivesmatter and #feesmustfall have initiated a return to the androcentric philosophies of Malcom X and Steve Biko, for example. As such Rankine and Putuma’s literature and art marks a reclamation of female empowerment and visibility in the face of a political rhetoric that continues to be masculine and nationalist in nature. In the absence of a space where Black female and queer bodies are adequately recognised, the poetry they write creates a space of self-representation and recognition.

- Description: Behavioural change is increasingly anticipated as an important pathway towards the reduction of the human footprint on the environment. Monitoring resource consumption at the household scale is essential as a basis for evaluating current performance and supports the understanding of how behaviour change interventions can be implemented. Yet, there are comparatively fewer studies on pro-environmental behaviour (PEB) in developing country contexts than in developed countries. Further, where research efforts have been made in developing countries, these have mainly focussed on low-income households. This means the extant literature on PEB is limited across a geographic and economic gradient, making generalisations about PEB problematic and limiting the scope for thinking about interventions for promoting pro-environmental behaviour in developing countries. In response to this, the study focuses on high-income households in Johannesburg, South Africa. Overall, the findings show a high level of heterogeneity in reported pro-environmental energy use behaviour, attributed to a suit of socio-demographic and value factors. Mainly, age, number of dependents, household size. Valuing leisure time were negatively correlated to energy use behaviours, while valuing environmental quality positively correlated to energy use behaviours. The provision of information energy-saving interventions yielded positive behavioural change as shown by reduced energy consumption of up to 12% in the Treatment group. However, no significant correlations were found between energy reduction and socio-demographic and personal value factors, which can be attributed to a different cultural context. The study discusses the implications of the findings on debates around pro-environmental behaviour and factors influencing pro-environmental behaviour, and provides further recommendations for future energy policies related to the household sector.

- Description: This thesis provides a statistical analysis of traveling ionospheric disturbances (TIDs) in South Africa. The velocities of the TIDs were determined from total electron content (TEC) maps using particle image velocimetry (PIV). The periods were determined using Morlet function in wavelet analysis. The TIDs were grouped into four categories: daytime, twilight, nighttime TIDs, and those TIDs that occurred during magnetic storms. It was found that daytime medium scale TIDs (MSTIDs) propagated equatorward in all seasons (summer, autumn, winter, and spring), with velocities of about 114 to 213 m/s. Their maximum occurrence was in winter between 15:00 and 16:00 LT. The daytime large scale (TIDs) LSTIDs propagated equatorward with velocities of approximately 455 to 767 m/s. Their highest occurrence was in summer, between 12:00-13:00 LT. Most of the these TIDs (about 78%) were observed during the passing of the morning solar terminator. This implied that the morning terminator was more effective in instigating TIDs. Only a few nighttime TIDs were observed and therefore their behavior could not be statistically inferred. The TIDs that occurred during magnetically disturbed conditions propagated equatorward. This indicated that their source mechanism was atmospheric gravity waves generated at the onset of geomagnetic storms.

- Description: This thesis aims to respond to the rise in the production of science fiction in Africa over the last decade, and to show how what I describe as the juju orientation of many of these works does not disqualify them from the genre of science fiction. Rather, I advocate for the recognition of juju ontologies as genuine sources of knowledge about the world, which have been overlooked by the globally dominant scientism that has informed science fiction theorisation to date. In my introduction I outline the theoretical frameworks of juju, science fiction and epistemology with which the thesis is in communication. In my second chapter I re-read Amos Tutuola’s novel The Palm-Wine Drinkard, showing the inherently science fictional structure of the juju-based storytelling that characterises colonial and pre-colonial African literature, as well as the essentiality of science fictional modes to Tutuola’s own prose. My third chapter considers Ian MacDonald’s theorisation of a jujutech aesthetic in African science fiction, wherein the speculations of the genres are rooted in both technoscientific and juju ontologies simultaneously. I account for the role this literary aesthetic plays in Ekari Mbvundula’s “Montague’s Last” to blur the divisions of worldly knowledge enforced by global epistemological inequalities, before showing how Dilman Dila’s A Killing in the Sun presents a critically frontier African epistemology in literary practice, and the value thereof. My fourth chapter considers the role of popular culture and consumption, and how the global literary industry resists juju-based texts. I conclude that juju-based nova and the jujutech aesthetic are not only essentially science fictional literary modes, but important players in science fiction’s role in being epistemologically productive in the future.

I account for the role this literary aesthetic plays in Ekari Mbvundula’s “Montague’s Last” to blur the divisions of worldly knowledge enforced by global epistemological inequalities, before showing how Dilman Dila’s A Killing in the Sun presents a critically frontier African epistemology in literary practice, and the value thereof. My fourth chapter considers the role of popular culture and consumption, and how the global literary industry resists juju-based texts. I conclude that juju-based nova and the jujutech aesthetic are not only essentially science fictional literary modes, but important players in science fiction’s role in being epistemologically productive in the future.

- Description: Every student has a unique mathematical lived experience: a unique amalgamation of ideas about mathematics, exposure to mathematical concepts and feelings about mathematics. A student's unique set of circumstances means that not every explanatory account of mathematics will cohere with her previous experiences. For an explanation to have explanatory potential, it must provide an account which coheres with the other beliefs a student has about mathematics. If an explanation has no such coherence, it will not be recognisable as an explanation of the phenomenon of mathematics for the student. Our explanatory accounts of mathematics and mathematical knowledge are our philosophies of mathematics. Different philosophies of mathematics will better explain different sets of mathematical lived experiences. In this thesis I will argue that students should be exposed to a multiplicity of philosophies of mathematics so that they can endorse the philosophy of mathematics which has the most explanatory potential for their particular set of mathematical lived experiences. I argue that this will improve student understanding of mathematics. The claims inherent in any given philosophy of mathematics, when combined with other stereotypes or prejudices, can work to unjustly exclude members of subordinated groups, such as poor, black or female students, from mathematical participation. If we want to avoid reinforcing and reinscribing prejudicial claims about people in the mathematics classroom, we need to be aware of how a certain philosophy of mathematics can exclude certain students. In this thesis I will be defending the idea that, as mathematics educators, we should diversify the way we see mathematics so that we decrease this exclusion from mathematics. In order to diversify the way in which we see mathematics so as to decrease unjust exclusion, members of subordinated groups should be encouraged to share their mathematical experiences in a space sensitive to the power dynamics present in the mathematics classroom. These accounts can then be combined with existing philosophies of mathematics to create new ways of making sense of mathematics which do not unjustly exclude members of subordinated groups.

- Description: [Editor's Letter]: Study South Africa has been the global mouthpiece of the International Education Association of South Africa (IEASA) and South African Higher Education since the publication of its first edition in 1999. It grew from a publication that served as a guide to South African Higher Education to a comprehensive source of information for the international academic community and others interested in South Africa’s tertiary education sector. This annual publication requires knowledgeable contributors as well as skilful editorial and other technical support. For the past number of years the editorial team was ably supported by Loveness Kaunda from the University of Cape Town (UCT). She provided the publication with her time, energy and knowledge. However, as she retired from her UCT position, she will no longer be available to consult with on a regular basis. This edition of Study South Africa is dedicated to her as a token of gratitude for all her time and passion. Another source of knowledge and inspiration is Patrick Fish - a higher education specialist who does research on topics relevant to the South African Higher Education landscape and provides us with up-to-date information. His writing skills turn the first number of pages of this publication into a real source of information. The knowledge about South African universities will be incomplete without the contributions of the universities themselves. A common trend this year is the focus on excellence of teaching and research as well as the relevance of South African Higher Education to local students functioning in an ever globalising world. It is also evident that most of the South African universities are aware of the need to be globally competitive, not only to attract the best international students, but also to be able to compete in a very competitive global knowledge driven environment. Study South Africa is again proudly presented by IEASA. This edition, focussing on Internationalisation of Higher Education, with a specific focus on South Africa in a changing world, again illustrates the interconnectedness of global higher education. It is envisaged that future editions will explore and document the collaboration between IEASA and similar organisations that is promoting the Internationalisation of Higher Education as well as global trends in international higher education affecting internationalisation of higher education in emerging countries. , 13th Edition

- Description: [Extract from article by Ms Merle Hodges]: A recent article points to the feeling of alienation that students feel when studying away from home. It seeks to address the problem by establishing a range of fora where foreign students can feel more ‘at home’. It encourages host students to be more willing to accommodate these ‘outsiders’ in order to boost the reputation of the institution. Most of these initiatives are slightly patronising, but obviously well-meant. The overriding sense behind the article is that international students, within higher education institutions, are a benevolent burden. International students should be looked after, because universities are generally maternal (they are someone’s alma mater after all), places of kindness (they literally give away knowledge) and generally care for others (community outreach is fundamental to most universities). More importantly, international students – in places like the USA and UK – generate additional funding in an environment where government and federal funding is drying up. But what if four out of every ten students in the world who graduated were from China and India? In the next eight years? That genial inconvenience now becomes an imperative. These are the predictions by such august organisations as The British Council and the education branch of the OECD. It is also anticipated that these countries will not be in a position to educate this number of students internally. Which, in turn, suggests that there will be mass outflows at the undergraduate level and, by sheer dint of numbers, also means that internationalisation is heading towards a compounding acceleration in numbers. Where then does internationalisation stand? It will no longer be an altruistic add-on, but core business to the lifeblood of the universities across the globe. As far back as 1994, Jane Knight understood internationalisation as a phenomenon that would have a profound impact on the functions and structures of the university. “Internationalization,” she points out, “is the process of integrating an international, intercultural, global outlook into the major functions of a university – teaching, SRC, and service functions.” Over the past year arguments have been made that suggest that global shifts in student demographics are not the ‘province’ of South African higher education and that our obligation is to focus internally, on poverty alleviation and job creation. This argument misses the point. The free flow of academics and students – especially the large number of postgraduate students from other countries already at our institutions – are working with our academics on solving exactly these kinds of problems. IEASA is no longer only about the 60 000 students who migrate to our shores annually. It’s about what they learn and the diverse experiences that they will go through; experiences that will change them for life and will inevitably bring them to a different understanding of the world that we, collectively, are presently fashioning. , 12th Edition

- Description: [Extract from message from Minister of Higher Education and Training, Hon. Dr BE Nzimande]: The 10th Edition focuses on the highly relevant issue of ‘Higher Education Internationalisation in the Development of Africa’. The internationalisation of higher education is of great importance for the continent, if Africa wants to be able to compete and participate in a global context. Currently, there are only three African institutions in the Top 500 of the Shanghai Academic Ranking of World Universities and all of these are in South Africa. Similarly, one South African institution appears in the Top 200 of the Times Higher Education World Ranking and no other African universities are represented. Despite being cautious about the methodology used to derive rankings, our aim in higher education should be to actively compete internationally and, more importantly, to serve the developmental challenges of Africa. It is imperative that Africa engages internationally and participates in the development of humanity’s knowledge. Research outputs and publications are particularly low on the continent, and African universities need to develop their research capabilities and direct resources to this important function. It is particularly important that research, which affects Africa and its development, is conducted on a large scale on the continent, supported by collaborative work and partnerships, rather than being carried out predominantly in other countries. The time has come for the tide to change and for our researchers and academics to focus on research opportunities presented on the continent. This is an important step for Africa to take if it is to deal effectively with the problems it faces and take its place in the international arena. One way to increase and develop knowledge outputs is through collaboration. An important opportunity for South African universities is the Erasmus Mundus Programme funded through the European Union (EU). This programme encourages collaboration between South African and European universities and provides resources for the exchange of staff and students within specific research programmes. It is also important for Africa to develop the research collaboration within the continent and with other developing and developed countries. In this regard, the Intra-ACP (Africa-Caribbean-Pacific) Scheme is of great importance. This initiative by the African Union (AU), working in collaboration with the EU, provides the opportunity for academic staff and student exchanges between universities in these regions. Intra-African exchanges are of particular importance in developing the continent’s capacity. Through such programmes African universities can work together to develop research and participate in the knowledge economy. We should also not ignore the challenges faced in improving the quality of teaching and learning in African universities, including many in South Africa. If sufficient attention and resources are not directed to improving these most basic activities of higher education, we will not only fail to meet the continent’s human resource development needs, but we will fail to establish the basis for future research advancement. Student mobility is very much a part of our fabric and provides the necessary intellectual stimulation, which is an essential part of student life. The number of African students from outside South Africa studying at South African institutions is growing annually, as is the number of non-African students. The networks established through such internationalisation are invaluable. There are also large numbers of our own students who, through universities’ reciprocal agreements, are studying abroad. The information provided in this publication provides a valuable opportunity to showcase our higher education sector and goes a long way to providing the necessary facts to encourage such student mobility. , 10th Edition

- Description: Trite as it may sound, the end of the Cold War is a landmark event in the history of human-kind. As such, this thesis was motivated by some of the international and local events that have taken place since the end of the 1980s. At the international level, the end of the Cold War has encouraged the re-examination of the concept of security. In Southern Africa too, this process has been strengthened by the demise of apartheid in South Africa. Initially challenged by a few academics, the traditional conception of security which perceived the threat to 'national' security primarily in the form of external military aggression no longer enjoys the primacy it was accorded during the Cold War era. A 'new' security discourse has emerged, and even though it has not yet made inroads into many governments' policy papers, there is some realisation that people's security concerns go beyond external military aggression to the state. Proponents of this 'new' thinking make reference to people-centred or human security - the notion that people and not the state, must be the objects of security. Arising from that, they point to the existence of many phenomena which should also be accorded security status especially in developing countries where people are confronted by life-threatening challenges such as disease, poverty, famine, and other challenges which do not necessarily threaten life, but if not tackled with urgency could transform themselves into the more conventional military threats. Here reference is made to the proliferation of small arms, political instability, mass migr?tions, and so on. In a region besotted by many of the challenges mentioned above, a security conception informed by the 'new' approach seems more appropriate. The outcome of the traditional approach to security is well known to the region many millions of lives were lost and it is estimated that billions of dollars in revenue were also lost, all in the name of maintaining the security of the South African state. Seeing neighbouring states as threats to its security because they accommodated liberation movements who occasionally instigated military attacks against Pretoria, the former apartheid state through its policy of 'Total Strategy' terrorised the entire region, including the majority of citizens within South Africa. However, since the end of apartheid in 1994, the new democratically elected South African government has committed itself to help build a politically stable, more secure, economically prosperous and integrated region. Through its accession to the Southern African Development Community (SADC), a body which it once tried to undermine, South Africa has further demonstrated a commitment to tackle some of the region's problems in unison with its former adversaries. Throughout the Southern African region there is a realisation that there are more long-term benefits to be gained by working together to tackle the challenges that confront almost all the countries in the region than trying to solve problems independently. Therefore through SADC, primarily a development-oriented body, Southern African states will also seek to address the region's security concerns. Many of the region's governments seem to show an understanding that security and development are intertwined - that they are two sides of the same coin whereby one cannot be attained without the other. Much as this understanding is laudable, in practice it does not seem as if it will translate to the prominence of so-called development issues or marginal security issues. Accepting the 'new' thinking on security also implies an acceptance of a wider range of security agents. It does not mean that by widening the agenda of security to include nonmilitary threats, more tasks will follow for the 'men' in uniform. What it means is that, the military establishment should no longer be the sole agent of security. Instead, where there is no military threat, resources should be channeled to other establishments such as those of health and research in order to fight the spread of AIDS. Furthermore, departments of water, environmental affairs, and so on, should be part of the security policy-making process. In addition, civil society should also be included in the policy-making process. Notwithstanding its limitations, and without undermining inter-governmental projects, civil society can at best promote security by serving as a watch-dog over policies adopted by governments. South Africa during the era of apartheid is a classic example of how governments cannot always be entrusted with the security of ordinary citizens. However, an examination of the structure and terms of reference of the newly created SADC Organ for Politics, Defence and Security (from henceforth referred to as the Organ) reflects a preponderance of the traditional/realist approach to addressing security concerns. It was conceived by, and is primarily constituted by the traditional establishments of security, that is, the military and the police. Some of the Organ's objectives include; security and defence cooperation through conflict prevention, management and resolution and mediation of disputes and conflicts. Nowhere is it evident that others besides those from a military/police background were involved in the formation of this important body. There is also no indication as to how other dimensions of security will be attained through the Organ. All this casts doubt regarding SADC's actual commitment to a development-oriented, people-centred and people-driven security. Nonetheless, current debates on security give hope to the notion that in the future, people's overall security needs will be addressed.

Much as this understanding is laudable, in practice it does not seem as if it will translate to the prominence of so-called development issues or marginal security issues. Accepting the 'new' thinking on security also implies an acceptance of a wider range of security agents. It does not mean that by widening the agenda of security to include nonmilitary threats, more tasks will follow for the 'men' in uniform. What it means is that, the military establishment should no longer be the sole agent of security. Instead, where there is no military threat, resources should be channeled to other establishments such as those of health and research in order to fight the spread of AIDS. Furthermore, departments of water, environmental affairs, and so on, should be part of the security policy-making process. In addition, civil society should also be included in the policy-making process. Notwithstanding its limitations, and without undermining inter-governmental projects, civil society can at best promote security by serving as a watch-dog over policies adopted by governments. South Africa during the era of apartheid is a classic example of how governments cannot always be entrusted with the security of ordinary citizens. However, an examination of the structure and terms of reference of the newly created SADC Organ for Politics, Defence and Security (from henceforth referred to as the Organ) reflects a preponderance of the traditional/realist approach to addressing security concerns. It was conceived by, and is primarily constituted by the traditional establishments of security, that is, the military and the police. Some of the Organ's objectives include; security and defence cooperation through conflict prevention, management and resolution and mediation of disputes and conflicts. Nowhere is it evident that others besides those from a military/police background were involved in the formation of this important body. There is also no indication as to how other dimensions of security will be attained through the Organ. All this casts doubt regarding SADC's actual commitment to a development-oriented, people-centred and people-driven security. Nonetheless, current debates on security give hope to the notion that in the future, people's overall security needs will be addressed.

- Description: Second year psychology students (N=176) from Rhodes University were surveyed using an anonymous questionnaire to obtain information on sexual behaviour and knowledge of the acquired immunodeficiency syndrome (AIDS) among young people. The following information was obtained: Knowledge of safe sex practices and HIV transmission was high although a number of misconceptions were noted. Only fifty six percent of students viewed oral sex with a condom as safe and thirty one percent do not consider mutual masturbation with a condom safe. Thirteen percent and twenty five percent respectively identified insects and saliva as being routes of HIV transmission. Magazines (96%), informal discussions with friends (95%), public pamphlets (86%) and public television (79%) were preferred sources of information. The students' knowledge did not appear to significantly affect sexual behaviour. Eighty percent of respondents were intimately involved with another person during the past twelve months, and only fifteen percent always made use of a latex barrier when being sexually intimate. Despite high rates of alcohol and/or drug consumption (80% of students use such substances), and the belief by the majority of respondents that alcohol and/or drugs facilitate higher risk behaviours, no support for the alcohol/risky sex hypothesis was found. Students were found to score highly on proneness to psychological and behavioural risk taking, and no significant relationship between this and unprotected sex was found. It can be concluded that educational programmes need to focus on what constitutes safe sexual practices in order to equip young adults with the knowledge they need to make informed choices regarding the relative risks of various sexual activities.

An investigation into the relationship between adolescent parasuicide, depressive illness and associated risk factors

- Description: This study aimed at investigating the relationship between adolescent parasuicide, depressive illness and associated risk factors. Reports worldwide indicate that suicidal behaviour in this age group has risen 150% over the past 20 years, whilst the rate for suicide in adults and the elderly has remained the same (Deykin et al, 1985; Neiger & Hopkins, 1988; Sudak, Ford & Rushforth, 1984a). In South Africa statistics confirm similar trends with regard to attempted and completed suicide. Statistics reveal that a high local incidence of adolescent suicide attempters are seen at psychiatric units. One pilot study recorded 187 adolescent suicide attempters during a three month period. This study was based on the hypothesis that the incidence of depressive illness in adolescent suicide attempters is higher than is generally accepted and that this condition often goes unrecognised and is misdiagnosed because it manifests differently with acting out behaviour and "masked" symptomatology. A random sample of suicide attempters between the ages of 13 - 25 who presented at C23 (psychiatric emergencies) Groote Schuur Hospital following a suicide attempt were assessed. 100 subjects were seen over a period of three months. The research procedure comprised a comprehensive assessment incorporating a semi-structured interview, self-report and objective rating scales for depression as well as instruments designed to assess the general health of each subject and their level of suicide intent. The depressive inventories used have been validated for use in this age group and were designed to elicit the associated features of adolescent depression. If warranted, a clinical diagnoses was given based on DSM 1V criteria. This diagnosis was substantiated by information from the research instruments which formed part of the assessment process. A high incidence of clinical disorders was diagnosed in the sample (86%). Depressive illness was found to be a significant risk factor for suicidal behaviour with 68% of the subjects suffering from an affective disorder and 21% reporting depressive symptoms. This study shows that the correlation between parasuicide and depressive illness is high enough to suggest that all suicidal behaviour in this age group should be taken seriously as parasuicide in itself is often a reliable indicator of an underlying depressive condition. Additional risk factors for adolescent parasuicide identified in this study correlated well with the findings of similar research studies. Psychiatric co-morbidity, especially substance use (42%) and cluster B personality factors (54%), were high and served to increase an individual's vulnerability to suicide risk. Psychosocial factors such as sexual abuse (28%) and physical abuse (37%) were also identified as high risk factors for adolescent suicidal behaviour. Individuals at risk for depression and suicidal behaviour typically came from broken homes which were disrupted and unsupportive. Family members were frequently abusing alcohol and 67% of the subjects reported the presence of psychiatric illness in the family. The preferred method of suicide attempt was an overdose (90%). These attempts were generally unplanned and impulsive with no disclosure prior to the event. Intent was usually high at the time of the act. It is only through identifying the risk factors specific to the developmental concerns of this age group and acknowledging the role of depressive illness in adolescent suicidal behaviour that effective preventative measures can be devised.
