- Description: [Extract from message from Minister of Higher Education and Training, Hon. Dr BE Nzimande]: It gives me pleasure to provide support to the International Education Association of South Africa’s (IEASA) 9th edition of the Study South Africa publication. The focus of this edition, which is Higher Education and Development in South Africa, is most appropriate today as South Africa continuously strives to ensure that higher education remains relevant and responsive to the developmental needs of the country. To this end, we always have to bear in mind that South Africa is a developing country, and as such still confronts challenges such as poverty and under-development. These challenges are characteristic of most developing countries, particularly in sub-Saharan Africa. Thus, our higher education sector, through its core functions of teaching, research, and community engagement, should seek to address these issues especially as they affect the poor and other vulnerable members of our society. Since we became a democratic state in 1994, South Africa has gone a long way to transform and restructure our higher education system to ensure amongst others equity with regard to the demographics of our staff and student population. The gender and racial profile of our students has improved significantly over the years to the extent that we now have black and female students constituting the majority at our institutions, especially at undergraduate level. It is also pleasing to note that our institutions enjoy good international standing. South African researchers and institutions continue to engage in research collaborations with their peers and counterparts around the world, and thus, are integral parts of research programmes and networks. With respect to student mobility, our higher education institutions continue to attract large numbers of international students, particularly from other parts of Africa. In 2007 the number of international students enrolled at our institutions was counted at 59 209, a significant increase from 44 439 in 2000. About 85% of these students originate from the African continent, more specifically the Southern African Development Community (SADC) region. Several factors account for the increase in the number of international students coming to South Africa. These include the country’s natural and ecological resources, rich and diverse cultural heritage, and the stable socio-political conditions. The consistent growth in the number of international students seeking to study in South Africa is a positive affirmation on the quality of the country’s institutions and the international reputation of their academics and qualifications. As a country, we see this growth as a positive development as it provides us with the opportunity not only to impart or relate our experiences, but also, to learn from others, and by so doing further enhance the international standing of our higher education system. , 9th Edition

- Description: Dwesa is a rural town situated in South Africa's Eastern Cape Province that has been selected as a testing site for an e-commerce project to address some of the challenges faced by the community. These challenges include difficulties stemming from poverty, poor access to public services, unemployment and low levels of literacy. The Siyakhula Living Lab project’s aim is to develop an e-commerce platform that will 'connect' the residents with the necessary access to services and markets by providing them with the necessary tools that can help in alleviating some of their challenges. In order for the project to achieve its objectives, a deeper understanding into the needs of the prospective users is required. User requirements elicitation deals with the process of interacting with the prospective users to understand and document their needs. This research aims at evaluating existing requirements elicitation techniques and methodologies in the context of rural information technology implementations. The primary objective is to develop a model for user requirements elicitation in Dwesa. Many requirements elicitation techniques and frameworks exist, but few have been evaluated in the context of rural software implementations. Requirements elicitation techniques should not be applied simply as steps to gather information. Instead this research project proposes a model that can be applied to assimilate the contribution of knowledge regarding the stakeholders, problem and solution characteristics, and other characteristics into the software development process for the effective elicitation of requirements.

- Description: Currently South Africa has the highest number of persons living with HIV-AIDS (PLWAs) in the world. Focus-group discussions conducted by Moon (2005:3) in the Eastern Cape indicated that people may not want to get tested for HIV or to access antiretroviral therapy (ART) for fear of disclosure of their HIV-positive status and of stigmatization. These findings prompted the researcher to conduct a study in this field. The objectives of this study are to explore and describe the experiences of PLWAs with regard to the comprehensive ART management received from registered nurses at selected public primary healthcare clinics in Nelson Mandela Bay; and to develop guidelines for registered nurses that could facilitate them in rendering appropriate comprehensive ART management. The research study is based on a qualitative, explorative, descriptive, phenomenological and contextual research design. The research population comprised of HIV-positive patients who received treatment at the selected public primary healthcare clinics. Criterion-based, purposive sampling was used to select participants for the interviews. Ten in-depth unstructured interviews were conducted. Data was then transcribed and coded. One central theme identified the fact that PLWAs experienced both positive and negative experiences at the clinics. The main findings of this research included evidence of various forms of stigma experienced by the PLWAs; distrust of the lay health counselors; but also that PLWAs were generally well-treated and satisfied with the service they had received. Broad guidelines for registered nurses was formulated that could facilitate them in rendering appropriate comprehensive ART management. The study concludes with recommendations made with regards to the areas of nursing practice, education and research. Throughout the study the researcher abided by the ethical considerations. The aspects of trustworthiness implemented in this study, included dependability, credibility, transferability and confirmability (Holloway & Wheeler, 2002:354).

- Description: The research conducted in this study focussed on advancing the knowledge database of diamineplatinum complexes on two frontiers: 1) the development of novel anticancer complexes, and 2) improvements in their synthetic chemistry. Novel square-planar dichloro and oxalato platinum(II) complexes were synthesized as potential anticancer agents in accordance with a comprehensive set of factors identified as being significant in optimizing such action. The nonleaving ligands consisted of asymmetric chelating chiral diamines of the form 1- (1-R-imidazol-2yl)(R')methanamine (R representing methyl, butyl and R' methyl, phenyl). The complexes were characterized by a host of spectral, thermal and crystallographic techniques. In addition, the stabilities of the complexes were monitored in aqueous and saline solutions. Cytotoxicity screening on three cultured cancer cell lines (MCF-7, HeLa and HT29) indicated the compounds, present as their respective racemates, to have rather modest activities relative to cisplatin; with complexes having the smallest substituents, R,R' = methyl, being most active. In recognition of the limitations of traditional silver-based syntheses of oxalatoplatinum(II) complexes, innovative non-silver methods were developed using the well known cancer drug, oxaliplatin, (trans-R,R-1,2- diaminocyclohexane)oxalatoplatinum(II), as a prototype. These involved direct ligand exchange reactions of the dichloro precursor, (trans-R,R-1,2- diaminocyclohexane)dichloroplatinum(II), with tetrabutylammonium oxalate in essentially non-aqueous solvents. A 90:10 mixture of isoamyl alcohol (3-methyl- 1-butanol):water, proved to be a promising solvent, enabling the recovery of pure oxaliplatin (~98 percent) after 9 hours at 88 °C in yields of up to 86 percent. In light of the perceived unique mode of anticancer action available to mononitroplatinum(IV) complexes (i.e. their STAT3-binding potential), octahedral diamineoxalatoplatinum(IV) complexes containing axially-coordinated nitro and halo co-ligands were synthesized and extensively characterized. Electrochemical studies revealed trends in reduction potential which could be correlated to structural / chemical traits of the coordinated diamine and axial ligands. The similarities of the determined cytotoxicities of the platinum(IV) compounds and their respective platinum(II) analogues, implicated reduction as a means of activation of the platinum(IV) complexes.

- Description: Traditional methods of providing public services to disadvantaged rural communities in South Africa have, over the years, proven to be inefficient and in most such communities, simply non-existent. Although the South African government has taken initiatives to make these public services cheaply and conveniently available online at national level, access at local municipal level is still lacking. The goal of this study is to develop a cost-effective e-government system that will contribute to improved provision of public services to the Dwesa area, a rural community in the Eastern Cape province of South Africa, by the government. A prototype construction approach was used, to develop a cost-effective four-modular web application. Interviews were conducted in the field, resulting in four e-government system modules, based on open-source software, developed and integrated to form a single, dynamic web component that will act as a one-stop shop for Dwesa community members. These are the Dwesa Online Application Centre (DOAC) to apply for important government documents and grants, the Dwesa Online Reporting Centre (DORC) to report various grievances to the responsible agencies, the Dwesa Forum Corner (DFC), a digital community, and the management back-end module. The Dwesa e-government portal was developed using Linux-Apache-MySQL-PHP (LAMP) technology, a Zoop framework to model the individual components and a JQUERY JavaScript library to increase the responsiveness of the user interfaces. The most significant contributions of this thesis have been the development of a cost-effective, integrated e-government functionality, applicable to disadvantaged communities, and the greater understanding this has given of the tools and methodologies that can be used to deliver public services efficiently to citizens. The final evaluation of this e-government system gives significant evidence that the e-government portal provides a solid foundation that will allow e-government implementation to raise the provision of public services to a higher level.

- Description: Both children and adults share a common, culturally distinct view of what it means to be male or female. These gender stereotypes are pervasive in society and daily social interactions, and influence all aspects of gender development (Golombok & Fivush, 1994). The inherent physical differences of boys and girls may have triggered the speculation and accompanying myths surrounding the existence of gender differences in childhood development. Many people believe that boys and girls follow a different developmental path that lead to gender differences in intellectual ability. An up-to-date and integrative review of theory and research on gender indicates two opposing perspectives on the topic, with substantial information supporting each view. However, this is the first study to examine and compare a sample of South African pre-school boys and girls from a truly holistic developmental perspective on the recently released Griffiths Mental Development Scales-Extended Revised (GMDS-ER). Developmental theorists have emphasized the profound impact early childhood development has on subsequent development, as it shapes the course of an individual’s life. Contemporary cognitive developmental theories, such as Demetriou’s (2000; 2004) developmental model of cognitive development, advance that child development does not progress in a fixed and predictable manner. Instead, Demetriou proposes that development occurs in a wave-like fashion, where the processes and functions of the various levels of the mind may be at differing points in their cycle of development. When one function progresses to a higher level, it unlocks the possibility for another function to advance to a different point in its cycle (Demetriou et al., 2002). As the significance of understanding the process of early childhood development more fully increases, so does the need to establish with more confidence the value and role of developmental assessment in the early identification of problems. The overall purpose of this study was to generate comparative information regarding the general development of a sample of 5- and 6-year-old South African pre-school boys and girls. Specifically, the study aimed to explore and describe the developmental profiles of pre-school boys and girls within the abovementioned age group with respect to their overall performance on the GMDS-ER as well as their performance on the six Subscales. Then, the mean General Quotients (GQ) and developmental profiles of the pre-school boys and girls obtained on the GMDS-ER were compared. An exploratory-descriptive quantitative research method was used. The sample (N = 64) was selected through a combination of non-probability, purposive and convenience xiii sampling. Within this framework, a between-subjects design in which matching was used to control extraneous variables, was employed. Data was analysed using descriptive statistics and independent sample t-tests to compare the GQs of the gender groups. A Hotellings T2 was used to compare the Subscale profiles. No significant gender differences were found when comparing the overall developmental and Subscale profiles of the boys and girls on the GMDS-ER. However, certain interesting trends did emerge from a review of the findings when compared to the literature review and previous studies. The information generated from this study has contributed to our knowledge base of the performance of South African children on the recently released GMDS-ER.

- Description: Common law does recognise the concept of dismissal based on operational requirements. It recognises dismissals that are based on breach of expressed or implied terms of contract of employment. The concept of operational requirements has its roots in the Labour Relations Act 28 of 1956. This Act recognised termination of employment of a number of employees due to ability, capacity, productivity, conduct and operational requirements and needs of undertaking industry trade or occupation of the employer as legitimate. Under the 1956 LRA, employers were allowed to dismiss employees if employees refused to accept the proposed change to conditions of employment. The dismissal is called lock-out dismissal. This kind of dismissal entitled employers to dismiss employees on condition that the dismissal was temporary and the workers would be re-employed when they agree to the demands of the employer. After the contract of employment was terminated between the employer and employees, the employer was allowed to implement the changes using scab labour. The 1995 Labour Relations Act introduced section 187(1)(c) that was intended to re-enforce the abolishing of the lock-out dismissal. This section strictly forbids the dismissal of employees in order to compel them to accept demands of the employer in matters of mutual interest. Such dismissals are regarded as automatically unfair. In terms of section 64(4) of the 1995 LRA employers are not permitted to unilaterally effect changes to employees’ terms and conditions of employment. They are required to seek and obtain consent of the affected employees. If employees refuse to accept the proposed changes, the employer can use lock-out as defence. Firstly, the employer can initiate lock-out until employees accede to its demand. Secondly, the employer can lock-out employees in response to the notice of strike or strike of the employees. The employer can use scab labour during this lock-out period. Unlike the lock-out dismissal, lock-out under the 1995 LRA does not include termination of contract of employment. iv In contrast, employers are allowed to dismiss employees who refuse to agree to change to their terms and conditions of employment on the ground of operational requirements provided a fair procedure is followed. This reason for dismissal is not viewed by the courts as a dismissal to induce employees to accept the demand of the employer. The question that this study seeks to examine is the relationship between automatic unfair dismissal in terms of section 187(1)(c) of the Labour Relations Act and dismissal for operational requirements. A dispute between the employer and employees regarding change to terms and conditions of employment is a mutual interest dispute; and it therefore falls under collective bargaining. The same dispute can easily fall to rights dispute, because the reason for the proposed change to the production system and demand to the pursuit of improved efficiency and better achievement of profit objective related to operational requirement. There is obvious overlap between operational requirements and wage work bargaining. In Schoeman v Samsung Electronics, the court held that the employer is entitled to run its business in a prosperous way and this may entail affecting changes to terms and conditions of employment when the market forces demand so. In Mwasa v Independent Newspapers, the court held that change to terms and conditions of service of an employee can be proposed as a way to avoid retrenchment; dismissal of employees for refusing to accept the change is not covered by section 187(1)(c). In Fry’s Metals v Numsa, the court has rejected the notion that there is tension between section 187(1)(c) and section 188(1)(a)(ii). The court held that section 186(1) refers to dismissal or termination of workforce with the intention to end the employment contract and replacing the workforce with employees that are prepared to accept terms and conditions of employment that suit the employer’s operational requirements. The court argued further that the meaning of dismissal should be a v starting point when one wants to dispute the two sections. On the other hand, section 187(1)(c) was effected with a certain purpose, which is to prohibit the employer from dismissing employees in order to compel them to accept its demand in dispute of mutual interest. The court held that the dismissal in this case was final. The employer dismissed its employees because it did not need them anymore. This dismissal is in accordance with section 186(1). The court rejected that operational requirements is confirmed to saving business from bankruptcy. The court argued that the principle includes measures calculated to increase efficiency and profitability. The employer can dismiss and make more profit.

- Description: Common law does recognise the concept of dismissal based on operational requirements. It recognises dismissals that are based on breach of expressed or implied terms of contract of employment. The concept of operational requirements has its roots in the Labour Relations Act 28 of 1956. This Act recognised termination of employment of a number of employees due to ability, capacity, productivity, conduct and operational requirements and needs of undertaking industry trade or occupation of the employer as legitimate. Under the 1956 LRA, employers were allowed to dismiss employees if employees refused to accept the proposed change to conditions of employment. The dismissal is called lock-out dismissal. This kind of dismissal entitled employers to dismiss employees on condition that the dismissal was temporary and the workers would be re-employed when they agree to the demands of the employer. After the contract of employment was terminated between the employer and employees, the employer was allowed to implement the changes using scab labour. The 1995 Labour Relations Act introduced section 187(1)(c) that was intended to re-enforce the abolishing of the lock-out dismissal. This section strictly forbids the dismissal of employees in order to compel them to accept demands of the employer in matters of mutual interest. Such dismissals are regarded as automatically unfair.

- Description: A basic ichthyofaunal and physico-chemical survey of the coastal outlets on the south coast of South Africa (Robberg Peninsula to Cape St Francis) was undertaken during November 1994 and September 1995. Some 27 systems were identified along this stretch of coast and of these, 48% (Brak, Helpmekaars, Klip, Witels, Geelhoutbos, Kleinbos, Bruglaagte, Langbos, Sanddrif, Eerste, Boskloof, Kaapsedrif and Klipdrif [Wes]) comprised the inlets of coastal streams that offer little habitat for fishes, 26% (Sout, Bloukrans, Lottering, Elandsbos, Storms, Elands and Groot [Oos]) are located within deeply incised valleys within the Tsitsikamma region and provide limited littoral habitat for estuary-associated fishes; 26% of the systems (Piesang, Keurbooms, Matjies, Groot [Wes], Tsitsikamma, Klipdrif [Oos], Slang) appear to serve some estuarine function for both marine migrant and resident species although some of these may also be limited due to their small size and infrequent connection with the sea. This study serves to emphasize the ecological importance of these latter estuaries within this coastal sector.

Modelling of size-based portfolios using a mixture of normal distributions

- Description: From option pricing using the Black and Scholes model, to determining the signi cance of regression coe cients in a capital asset pricing model (CAPM), the assumption of normality was pervasive throughout the eld of nance. This was despite evidence that nancial returns were non-normal, skewed and heavy- tailed. In addition to non-normality, there remained questions about the e ect of rm size on returns. Studies examining these di erences were limited to ex- amining the mean return, with respect to an asset pricing model, and did not consider higher moments. Janse van Rensburg, Sharp and Friskin (in press) attempted to address both the problem of non-normality and size simultaneously. They (Janse van Rens- burg et al in press) tted a mixture of two normal distributions, with common mean but di erent variances, to a small capitalisation portfolio and a large cap- italisation portfolio. Comparison of the mixture distributions yielded valuable insight into the di erences between the small and large capitalisation portfolios' risk. Janse van Rensburg et al (in press), however, identi ed several shortcom- ings within their work. These included data problems, such as survivorship bias and the exclusion of dividends, and the questionable use of standard statistical tests in the presence of non-normality. This study sought to correct the problems noted in the paper by Janse van Rensburg et al (in press) and to expand upon their research. To this end survivorship bias was eliminated and an e ective dividend was included into the return calculations. Weekly data were used, rather than the monthly data of Janse van Rensburg et al (in press). More portfolios, over shorter holding periods, were considered. This allowed the authors to test whether Janse van Rensburg et al's (in press) ndings remained valid under conditions di erent to their original study. Inference was also based on bootstrapped statistics, in order to circumvent problems associated with non-normality. Additionally, several di erent speci cations of the normal mixture distribution were considered, as opposed to only the two-component scale mixture. In the following, Chapter 2 provided a literature review of previous studies on return distributions and size e ects. The data, data preparation and portfolio formation were discussed in Chapter 3. Chapter 4 gave an overview of the statistical methods and tests used throughout the study. The empirical results of these tests, prior to risk adjustment, were presented in Chapter 5. The impact of risk adjustment on the distribution of returns was documented in Chapter 6. The study ended, Chapter 7, with a summary of the results and suggestions for future research.

- Description: This study critically examines my classroom practice in teaching young learners aged four-and-a-half to six years old. It focuses on the following research question: How can I create a stimulating environment in my classroom to promote awareness of and a love for reading? My classroom-based action research methodology places me, the practitioner, at the centre of the investigation. The work examines closely my professional values and my strong belief in the capacity of learners to be curious, absorb and make sense of what they encounter and experience in a stimulating environment. It investigates how such an environment develops the potential of learners to love and embrace reading. The process of engaging reflectively and analytically in practitioner research has helped me to gain a better understanding of my learners’ needs and to improve the ways in which I promote reading in the reception year of formal schooling. I claim that the creating of a stimulating environment in my classroom is grounded in my ability to motivate, model and scaffold the learners to engage in reading confidently. Together, the learners and I have created a living theory of education, one that is open to further reflection and development. Ongoing interaction between theoretical discourse and practical experiences enable me to develop my professional knowledge and to synthesize my values and practice. The investigation continuously confirms the advantages of a print-rich environment and how it can be used to promote a love for reading amongst young learners. The claims and knowledge generated in this study are personal and true for me, while the living transformational process demonstrates how I have developed professionally.

- Description: Information and Communication Technologies (ICTs) have been widely deployed in developmental programs and this has lead to the creation of a new field – ICT for Development (ICT4D). Within the context of ICT4D, various e-services are being developed, including e-Commerce, e-Government, e-Health and e-Judiciary. ICT4D projects allow Small, Medium and Micro Enterprises (SMMEs) in rural areas to increase sales and gain a market share in the global market. However, many of these ICT4D projects do not succeed, because they fail to bring enough financial value to SMMEs due to the form they currently have. An obvious example is e-Commerce, which should be a source of revenue for business organizations, but most often is not. This thesis presents the design and implementation of a rewarding and negotiation application for a shopping portal to improve the marketing of products for rural entrepreneurs. The shopping portal has been set up for the Dwesa community, a marginalized area in the Eastern Cape province of South Africa. The proposed system, called the Dwesa Rewarding Program (DRP) enables customers buying online to get points for some of the activities carried out on the shopping portal. It also allows customers to negotiate and make offers whilst purchasing and get rewarded for buying online. The novelty of the system is in its flexibility and adaptability. One achievement of this system is the establishment of negotiation rules which allows fairness in rewarding customers. This should in turn lead to increased sales on the e-Commerce platform in marginalized areas and subsequently increased effectiveness of ICT4D for socio-economic development

- Description: Given the growing effect that globalisation and integration has had upon economies and regions, the process of monetary union has become an increasingly topical issue in economic policy debates. This has been driven in part by the experience and successes of the European Monetary Union (EMU), which is widely perceived as beneficial to member countries. The Southern African Development Community (SADC) is an example of a group of countries that has realised that there are benefits that may arise from economic integration. This paper makes use of an interest-rate pass through model to investigate whether the pass-through of monetary policy transmission in ten SADC countries has become more similar between January 1990 and December 2007 using monthly interest rate data. This is done to determine the extent of macroeconomic convergence that prevails within SADC, and consequently establish whether the formation of a regional monetary union is feasible. The results of the empirical pass-through model were robust and show that there are certain countries that have a more efficient and similar monetary transmission process than others. In particular, the countries that form the Common Monetary Area (CMA) and the Southern African Customs Union (SACU) tend to show evidence of convergence in monetary policy transmission, especially since 2000. In addition, from analysis of the long-run pass-through, the results reveal that there is evidence that Malawi and Zambia have shown signs of convergence toward the countries that form the CMA and SACU, in terms of monetary policy transmission. The study concludes that a SADC wide monetary union is currently not feasible based on the evidence provided from the results of the pass-through analysis. Despite this, it can be tentatively suggested that the CMA may be expanded to include Botswana, Malawi and Zambia.

- Description: The Putranjivaceae is an enigmatic family, notable for being the only lineage outside the Capparales to possess the glucosinolate biochemical pathway, which forms the basis of an induced chemical defense system against herbivores (the “ mustard oil bomb ” ). We investigated the pollination biology and fl oral scent chemistry of Drypetes natalensis (Putranjivaceae), a dioecious subcanopy tree with fl owers borne on the stem (caulifl ory). Flowering male trees were more abundant than female ones and produced about 10-fold more fl owers. Flowers of both sexes produce copious amounts of nectar on disc-like nectaries accessible to short-tongued insects. The main fl ower visitors observed were cetoniid beetles, bees, and vespid wasps. Pollen load analysis indicated that these insects exhibit a high degree of fi delity to D. natalensis fl owers. Insects effectively transfer pollen from male to female plants resulting in about 31% of female fl owers developing fruits with viable seeds. Cetoniid beetles showed signifi cant orientation toward the scent of D. natalensis fl owers in a Y-maze olfactometer. The scents of male and female fl owers are similar in chemical composition and dominated by fatty acid derivatives and isothiocyanates from the glucosinolate pathway. The apparent constitutive emission of isothiocyanates raises interesting new questions about their functional role in flowers.

- Description: The Putranjivaceae is an enigmatic family, notable for being the only lineage outside the Capparales to possess the glucosinolate biochemical pathway, which forms the basis of an induced chemical defense system against herbivores (the “ mustard oil bomb ” ). We investigated the pollination biology and fl oral scent chemistry of Drypetes natalensis (Putranjivaceae), a dioecious subcanopy tree with fl owers borne on the stem (caulifl ory). Flowering male trees were more abundant than female ones and produced about 10-fold more fl owers. Flowers of both sexes produce copious amounts of nectar on disc-like nectaries accessible to short-tongued insects. The main fl ower visitors observed were cetoniid beetles, bees, and vespid wasps. Pollen load analysis indicated that these insects exhibit a high degree of fi delity to D. natalensis fl owers. Insects effectively transfer pollen from male to female plants resulting in about 31% of female fl owers developing fruits with viable seeds. Cetoniid beetles showed signifi cant orientation toward the scent of D. natalensis fl owers in a Y-maze olfactometer. The scents of male and female fl owers are similar in chemical composition and dominated by fatty acid derivatives and isothiocyanates from the glucosinolate pathway. The apparent constitutive emission of isothiocyanates raises interesting new questions about their functional role in flowers.

- Description: Water hyacinth, Eichhornia crassipes (Martius) Solms-Laubach (Pontederiaceae), a free floating aquatic plant was discovered by C. von Martius in 1823 in Brazil. It is believed to have been introduced into South Africa, as an ornamental plant, in 1908 to the Cape Province and Natal. Since its introduction, water hyacinth has spread throughout South Africa to the detriment of all aquatic systems that it has been introduced to directly or indirectly. The weed was first positively identified on the Nseleni and Mposa rivers on the Nseleni Nature Reserve which is a protected area near Richards Bay in KwaZulu- Natal in 1982 and formed a 100% cover of the river by 1983. An integrated management plan was implemented in 1995 and resulted in a reduction of the weed from a 100% cover to less than 20% cover in 5 years. The keys to success of the water hyacinth integrated management plan, presented here, were finding the source of the weed, mapping the extent of the water hyacinth infestation, identifying sources of nutrient pollution, appointing a champion to drive the programme, dividing the river into management units, consultation with interested and affected parties, judicious use of herbicides and biological control and a commitment to follow-up. This study further showed that water hyacinth on the Nseleni and Mposa river systems had a negative impact on the biodiversity of the protected area and the control of water hyacinth resulted in the recovery of the benthic invertebrate, amphibian, reptile, fish and avian fauna. The implementation of this integrated management plan was very cost-effective and serves as a model approach to the control of water hyacinth in both South Africa and the rest of the world.

- Description: The provision of psychological services is vital considering the complex nature of psychosocial issues facing people today. Nevertheless, the provision and utilization of psychological services has not been given due recognition in most African countries, including Botswana. Botswana is one of the countries faced by the challenges of the HIV/AIDS pandemic and other mental health problems, as well as poverty and unemployment. To date statistics on the magnitude of the HIV/AIDS epidemic in Botswana, published annually by the National AIDS Coordinating Agency (NACA) reflect an increased rate of mental illness and psychosocial problems. Considering the complex nature of issues that impact negatively on people in Botswana, there is a need for awareness and the provision of psychological services in the primary health care system. There is little research on the place of psychology and psychological services in Botswana. The availability of such information is crucial for the planning of effective community-based psychological services. The present study employed a quantitative research method to explore and describe awareness and attitudes towards psychological services and referral practices in relation to psychological problems, of health care providers in Botswana. The participants in the study were chosen, based on a non-probability, purposive sampling method. The sample consisted of ninety-six persons and constituted medical doctors, nurses, psychiatrists, psychiatric nurses and clinical social workers from governmental and non-governmental institutions from Gaborone and Francistown in Botswana. Data were analyzed by means of descriptive statistics in order to identify the mean, ranges and standard deviations. Frequency counts and percentages of the participants’ responses were computed. The results of the study revealed an awareness of available psychological services, positive attitudes towards psychology and psychological services and a reasonable percentage of referrals to psychological services. The results also revealed that available psychological services were limited and not easily accessible to patients. There was also an indication of a shortage of trained professionals to offer psychological services in health care centres, which resulted in psychological problems being referred to social workers.

- Description: Interest in the use of low-valent titanium species as reagents in organic synthesis began with Van Tamelen and his research team in 1965, when they reported the first ever low-valent titanium-induced reductive dimerization of alcohols to give hydrocarbons [1]. In the early seventies shortly after the Van Tamelen report, the research teams of Mukaiyama,[2] Tyrlik[3] and McMurry[4] made the independent and simultaneous discovery that ketones and aldehydes undergo reductive dimerization to yield olefins on treatment with low-valent titanium reagents. Particularly McMurry and his co-workers [5,6,7] have extensively investigated this reaction, therefore this process is now generally referred to as the “McMurry reaction”.

- Description: An important focus of peacebuilding as a part of post-conflict reconstruction is the provision of basic needs. Peacebuilding is a move from war to a peaceful future. Peacebuilding rests on the premise that provision of people’s needs eliminates unrest and lawlessness that arise due to war. This in turn prevents a relapse into war. Also, communities that experience war lose many years and tend to develop at slower rates than peaceful areas, if at all they do develop. The twenty year old war in Northern Uganda has caused a gap between this area and the rest of the country. Poverty has left many unable to provide basic needs. Peacebuilding efforts have been undertaken by Non Governmental Organizations, Community Based Organizations, Government of Uganda as well as people in the community organizing themselves into groups to enable them reconstruct their lives. Efforts are being made towards reconstruction, resettlement, reconciliation and providing relief in an effort to move from war and destruction. In many societies, women are left out, marginalized and discriminated against as a result of patriarchy. Their roles in peacebuilding are not considered important and they face many challenges in their efforts to rebuild their lives and families. This research focused on the challenges faced by women in Gulu, a district in the Northern region of Uganda in peacebuilding. Through conducting face to face interviews, and consulting documents available to the public, the researcher collected information about the challenges faced by the Acholi women, the women of Gulu district.

- Description: The relationships between the spatial distribution of gully erosion and topographic thresholds in the form of slope angle, position and configuration, as well as land use change in the form of abandoned lands were examined in several affected catchments of the Eastern Cape Province, South Africa. Land use and permanent gullies were mapped, digitized from orthophoto maps in Arc/info 3.5.2 GIS and converted to shapefiles using ArcView 3.2 GIS. Relationships between the mapped phenomena and topographic variables were sought using a Digital Elevation Model (DEM) in Idrisi Kilimanjaro GIS. A comparison between areas with a high potential for gullying and actual gully erosion was made using the Stream Power Index (SPI) as a surrogate for critical flow shear stress. Field surveys were also conducted to assess the present condition of the gullied sites as well as to validate DEM derivations. Seventy five percent of the gullied area was noted to lie on abandoned lands. A predominance of gullying in concave bottom lands was also identified. The SPI values highlighted a distinct preferential topographic zone for gully location. A conceptual model depicting the interaction between land use and topographic parameters to induce gully erosion was developed. This should assist local authorities to develop a policy regarding management of abandoned lands.
