- Description: The first democratically elected government in South Africa came into power in 1994 and with this the whole country faced changes and new challenges. The construction industry faced the challenge of incorporating and empowering previously disadvantaged people that were part of the industry as well as new emerging contractors that entered the industry. Various training and mentoring programmes were initiated by government as well as quasi-government institutions which attempted to address these challenges. Having an effective mentoring programme in place in the construction industry is critical to the development and growth of the emerging contractors as well as the industry as a whole. This research focuses on a specific programme to establish if the need for training and mentoring programmes exist and which specific aspects of the training need the most attention. The study furthermore, investigates the effect the programme had on emerging contractors on the specific programme. Primary data was collected by means of a telephonic questionnaire to emerging contractors on the mentoring programme as well as the mentors and service providers of the programme. Secondary data was obtained from the literature reviewed and from relevant publications. The main findings were that a need for the training and mentoring of emerging contractors exists and the study emphasizes that there is a demand for the ongoing monitoring of emerging contractors after completion of the programme. The study furthermore reveals that all aspects of the training and mentoring programme is important but more time and effort should be spent on the management and financial aspects of the programme The research is limited to emerging contractors and mentors who participated in the East Cape Development Corporation (ECDC) mentoring programme in the Eastern Cape and is limited to two specific regions namely Port Elizabeth and East London. The findings from the study could be used by training providers as well as mentors to enhance the existing programme to ensure proper rounding of the emerging contractors.

- Description: The purpose of the research was to assess the policy impact of the Land Redistribution and Development (LRAD) Programme, which substituted the Settlement and Land Acquisition Grant (SLAG) programme. Both these policies were meant to make land accessible to previously disadvantaged groups including Africans, Coloureds and Indians, as part of land reform policies of the post 1994 democratic government. Due to some failures of SLAG after its first five years of implementation, which were from 1995 to 1999, the land redistribution policy was revised and the LRAD programme came as an improved policy of SLAG. There has not been much research on the impact of this programme, which has been implemented since August 2001.

- Description: Organizations globally are challenged with a very volatile, fast changing environment. It is only those organizations that develop the capacity to change timeously that will survive in this millennium. (Meyer & Botha, 2000, p.23) Organizational development (OD) is a planned change approach aimed at changing behaviour and enhancing organizational effectiveness. Central to such an approach is continuous business process improvement. OD rests on the foundation of values and assumptions about people and organizations, and it is imperative that organizations adopt systematic methodologies in introducing business improvement interventions. The study introduced an OD approach to one of the rural primary schools in the Omusati region of Namibia, with the purpose of examining if it would bring change in the school. My goal was to explore participants' experience and perception of the OD process and to investigate the possible short term outcome of such an intervention. The case study involved 16 staff members made up of a principal, one head of department and 14 teachers. Data was gathered through formal interviews with the principal, head of department and three teachers, through a focus group interview with teachers, and through observation and observation note entries. The study found that OD was a new concept approach to the participants which differs completely from the way that change processes are introduced in the schools. Participants felt that introducing change in an organization using an OD approach can bring effective change, but it can also place huge demands on participants' commitment. This is particularly so if they do not adopt it as an internal process of business improvement. The OD approach is a long-term change process and not a quick fix. Finally, the outcome of the intervention indicated enthusiasm for the school to continue addressing the prevailing challenges despite various obstacles that they do not have control over.

- Description: The research was conducted in the Hewu area situated between Queenstown (20 km) and Whittlesea (15km) in the Eastern Cape Province of South Africa. In this area communal farming is practiced. Livestock and livestock products (wool) are the main sources of income. The farmers are mainly farming with Merino and Döhne Merino sheep. The lack of management systems (production, reproduction and management) for communal farmers resulted into ineffective communal farming defining the research problem. The research objectives set were: • To establish production norms for wool sheep. • To establish reproduction norms for wool sheep. • To establish effective management practices for wool sheep farmers. • To examine key constraints of wool sheep farmers. The farmers shear their sheep every 12 months usually in October of every year. The average wool production per sheep is 2.17kg. The clip averages a fineness of 19.1-20 micron. That is far below the wool production of the commercial farmers of the Eastern Cape who are producing between 4kg to 5kg per sheep at an average growing period of 12 months. The lack of proper fencing and camps causes major reproduction problems. The lambing percentage of the ewes is 94.85 percent. The weaning percentage referring to the reproductive efficiency of the mated ewes is only 17.24 percent. The survival rate of the lambs born alive is only 18.18 percent. Reproduction is the biggest problem of communal farms. Effective livestock- and grazing management systems for communal areas are essential for the successful development of farmers on communal grazing areas. Unfortunately the Hewu farmers still have many problems effecting their wool production and the production of lambs.

- Description: Heat generation during the FTSW process plays and important role in determining the characteristics of the weld. In order to obtain temperature fields, a transient temperature heat analysis is required. An area is the maximum temperatures reached within the base material during the FTSW process. These temperatures will be measured during experimentation, and compared to the welding simulation done using FEA. From the literature search it appeared that no heat transfer analysis had been done using finite element methods.

- Description: The dissertation focuses on the analysis of the extended defects present in as-grown and proton bombarded β-SiC (annealed and unannealed) grown by chemical vapour deposition (CVD) on (001) Si. The proton irradiation was done to a dose of 2.8 × 1016 protons/cm2 and the annealing took place at 1300°C and 1600°C for 1hr. The main techniques used for the analysis were transmission electron microscopy (TEM) and high resolution TEM (HRTEM). From the diffraction study of the material the phase of the SiC was confirmed to be the cubic beta phase with the zinc-blende structure. The main defects found in the β- SiC were stacking faults (SFs) with their associated partial dislocations and microtwins. The SFs were uniformly distributed throughout the foil. The SFs were identified as having a fault vector of the type 1/3 <111> with bonding partial dislocations of the type 1/6 <121> by using image simulation. The SFs were also found to be predominantly extrinsic in nature by using HRTEM analysis of SFs viewed edge-on. Also both bright and dar-field images of SFs on inclined planes exhibited symmetrical and complementary fringe contrast images. This is a result of the anomalous absorption ratio of SiC lying between that of Si and diamond. The analysis of the annealed and unannealed irradiated β-SiC yielded no evidence of radiation damage or change in the crystal structure of the β-SiC. This confirmed that β-SiC is a radiation resistant material. The critical proton dose for the creation of small dislocation loops seems to be higher than for other compound semiconductors with the zinc-blende structure.

- Description: The methanol extract of Helichrisum pedunculatum was screened for antimicrobial activity up to a concentration of 5 mg/ml using the agar dilution technique. A number of test bacterial isolates, comprising both Gram negative and Gram positive organisms were susceptible to the crude extract of the plant. The minimum inhibitory concentrations (MICs) of the extract ranged between 1 and 5 mg/ml for the susceptible organisms. The MICs of the selected antibiotics, chloramphenicol and penicillin, ranged between 2 and 4 mg/L, and 2 and 32 mg/L respectively against Bacillus cereus, Proteus vulgaris and Staphylococcus aureus OKOH1. Bactericidal activity was determined by the time kill assay. The methanol extract of the plant was not bactericidal at 1 × MIC for B. cereus, P. vulgaris and Staph. aureus OKOH1. At 2 × MIC the extract was bacteriostatic against B. cereus but bactericidal against P. vulgaris and Staph. aureus OKOH1. Combination studies were done at 1/2 × MIC, 1 × MIC and 2 × MIC of the plant extract with 1 × MIC of the antibiotics. Combinations of the plant extract and chloramphenicol resulted in mostly indifferent interactions against P. vulgaris and Staph. aureus OKOH1 but synergistic interactions at higher concentration of the plant extract for B. cereus. Penicillin combinations gave synergistic interactions at lower concentrations of the plant for P.vulgaris and Staph. aureus OKOH1 but was mostly indifferent for B. cereus.

- Description: Baylis-Hillman reactions of 2,2’-dithiodibenzaldehyde with the acyclic alkenes, methyl vinyl ketone (MVK) and methyl acrylate have afforded the thiochromene derivatives in moderate yields, and this approach has been extended to the use of the cyclic alkenes, 2-cyclohexenone and 2-cyclopentenone to afford the tricyclic analogues. In all cases, reduction of the disulphide link and intramolecular cyclisation occurred in situ, and a preliminary kinetic study of this reaction using the acyclic substrates MVK and methyl acrylate was undertaken with the aim of elucidating the mechanism involved. The results obtained showed that the consumption of both 2,2’-dithiodibenzaldehyde and MVK and/or methyl acrylate followed 1st-order kinetics during the initial stages of the reaction, but then deviated from 1st-order linearity. The reaction with methyl acrylate was much slower than with MVK, and the kinetic data indicates the mechanism to be more complex than anticipated. Conjugate addition reactions of methyl acrylate-derived 2-nitrobenzaldehyde Baylis-Hillman adducts with the amines, piperidine and benzylamine, afforded a range of conjugate addition products as diastereomeric mixtures in excellent yield (80-100%). Catalytic hydrogenation of the conjugate addition products using a Pd-C catalyst in ethanol, has afforded the corresponding, novel 3-amino-2-quinolone derivatives in lower yield (22-37%).The application of [superscript 13]C NMR prediction programmes to selected compounds synthesized in this study has revealed reasonable correlations between the experimental and predicted values.

- Description: It is important to the survival of the Africa Penguin (Spheniscus demersus) population that breeding at the nest site is successful and that large numbers of chicks are fledged into the breeding population. Nest distribution on Bird Island is not random and locality preferences for breeding exist. Although it seems that sufficient area exists on Bird Island for penguin nests, it can hardly be considered as suitable to optimise breeding. During prolonged heat conditions, breeders relocated to nest sites that were sheltered. Nests that were below ground in burrows was the only habitat that did not suffer nest desertion whilst all the other habitat types (including those that were sheltered) experienced 2-3 fold declines in nest numbers. Nests density and the selection of suitable nest sites are significantly influenced by the stage of breeding that the majority of birds are in, yet nests that are shaded, well-ventilated and protected seem to be the most preferred sites for breeding. Adults that attempt to breed are considered then to be in a healthy condition and will usually lay a double clutch (Randell 1983). The frequency of double clutches being laid during the peak breeding attempt was significantly higher compared to the replacement one. Breeding failure was fairly similar to breeding success during the incubation stage for nests with double clutches however, was substantially higher in single clutches. The growth rate of chicks was best fit to the von Bertalanffy growth curve in 90 percent of the cases. The overall growth rate of chicks from double broods was faster than from single broods, however was not significant. A-chicks maitain a high growth rate until they fledged. Yet, the sibling B-chick recorded the lowest growth rate of the successfully fledged chicks and up to until day 30 recorded a similar weight to those chicks that failed to fledge. Contrary to findings of Randall (1983), chicks from single broods delayed fledging, recorded lowest overall growth rates and experienced the greatest weight loss of all groups, yet fledged successfully. In order for chicks to fledge successfully, they needed to obtain a weight of 1060 g before day 30.5 in their growth cycles to avoid death due to startvation later on. Single chicks that are raised from a double cluth, fledged more other than chicks raised from a single clutch. Unfit or ill-adapted breeders that are marginal in the capabilities of raising offspring, already manifest in a small clutch size and offspring unable to obtain adequate weights during the initial stages of growth.

The overall growth rate of chicks from double broods was faster than from single broods, however was not significant. A-chicks maitain a high growth rate until they fledged. Yet, the sibling B-chick recorded the lowest growth rate of the successfully fledged chicks and up to until day 30 recorded a similar weight to those chicks that failed to fledge. Contrary to findings of Randall (1983), chicks from single broods delayed fledging, recorded lowest overall growth rates and experienced the greatest weight loss of all groups, yet fledged successfully. In order for chicks to fledge successfully, they needed to obtain a weight of 1060 g before day 30.5 in their growth cycles to avoid death due to startvation later on. Single chicks that are raised from a double cluth, fledged more other than chicks raised from a single clutch. Unfit or ill-adapted breeders that are marginal in the capabilities of raising offspring, already manifest in a small clutch size and offspring unable to obtain adequate weights during the initial stages of growth.

- Description: The forensic application of entomology is well known, but it is generally a field which concentrates on Diptera. Many Coleoptera also have forensic application, but are generally neglected by forensic entomology researchers. Necrophilic Coleoptera are diverse and therefore have application in estimating Post-Mortem Interval (PMI) by community composition, but they are also valuable in estimating PMI by development. In addition, Coleoptera are more common in stored product cases. Six species of forensically important Coleoptera were studied, three from the family Dermestidae (Dermestes haemorrhoidalis, D. maculatus and D. peruvianus) and three from the family Silphidae (Silpha punctulata, Thanatophilus micans and T. mutilatus). The effect of killing method and storage time on larval length was investigated in T. micans. Coleopteran larvae were shown not to behave in the same way as dipteran larvae. In contrast to dipteran larvae, it is recommended that coleopteran larvae be killed using ethanol. A development model is presented for T. micans. This represents the first statistically robust development model for forensically important Coleoptera, and the first development model for forensically important Silphidae. The model offers a method of estimating PMI which can be used once Diptera are no longer present on a corpse. Upper lethal temperature limits for four species of carcass beetle were determined. A comparison between species shows distinct differentiation between families and species. This differentiation accounts for microhabitat differences which these species show on carcasses. Bioclimatic models for the six species showed contrasting distributions, with both widespread and localised species. These models allow forensic investigators to assess whether the absence of a species from a corpse is forensically significant, or a result of the species distributions. Moisture-related variables were shown to be more important in predicting species distributions than temperature at a regional scale. Forensic entomology standards can be adjusted based on the findings of this study. Length was again shown to be an inferior measurement of larval age. Coleopteran development has been shown to be useful, and should be given greater consideration in future work. T. micans has been shown to be capable of locating and ovipositing on carcasses promptly after death, making it a good forensic indicator. Further work is needed for the full potential of necrophilic Coleoptera to be realised.

- Description: This dissertation summarises an analysis and assessment of the application of Quality Management Systems (QMS) by Small, Medium and Micro Enterprises (SMMEs), in the Engineering Manufacturing Sector of the greater Cape Town Metropolitan area. An outline of the existing hypothesis derived from previous international SMME studies related to the adoption of QMS by SMME’s, the management’s understanding of quality principles, the potential business benefits of QMS and the reasons for implementing Quality Management systems are given as background to the study. The dissertation includes a discussion of literature on the state of QMS in SMMEs, in particular, recent international research literature hypothesising that SMME management lack essential QMS knowledge and that, in general, most SMME’s do not have a QMS and that SMMEs only implement a QMS as a result of contractual pressures / requirements. Also reported are the results and findings of a survey conducted to test the validity of the existing hypotheses amongst a representative sample of Engineering Manufacturing SMMEs registered with the Cape Regional Chamber of Commerce and Industry in the Western Cape. Results of the survey indicate that almost 90 percent, of the companies surveyed had some type of Quality management System, the only two companies that reported not having a QMS, were companies classified as “Micro”, in terms of the National Small business Act. Analysis of the response to the survey concludes that, in general, more than 80 percent of Engineering SMMEs in the Manufacturing Sector have adopted a QMS based on ISO 9001 and that, on average, their management have a medium to high level of understanding of QMS and the associated business benefits. It is also apparent from survey responses, that companies classified as “Micro” in terms of the Small Business Act of 1996, do not see the need for a formal QM system as the owners of these companies consider them too small for a formal QMS. Instead they take direct ownership of their service and product quality in the face of the customer.

- Description: This study assessed the prevalence of unwanted early sexual experiences (UESE), of the first year psychology students at the University of Fort Hare, in East London. Of the participants, 65 (31 percent) indicated that they had been exposed to some form of non-contact (56.9percent) or contact (22.3 prercent) UESE before the age of 16 years. It was found that more male (42.5 percent) than female (25.2 percent) students reported being exposed to an UESE. The most common perpetrator reported by the majority of the participants were friends (52.4 percent). Most respondents reported that they were only exposed to the UESE once (55.6 percent). The study found that females were significantly more bothered than males both at the time of the UESE and at the time of completing the questionnaire. Both male and female participants were more bothered by the UESE at the time of the event than they were at the time of completing the questionnaire, which indicates an abatement of symptoms over time. The results indicate that flashbacks of the UESE were the most bothersome experience for both male and female participants at the time of completing the questionnaire.

The aim was to analyse and evaluate the policy and implementation framework underpinning the MURP within the auspices of the national Urban Renewal Programme (URP). During the course of the study, literature was reviewed with the aim of contextualizing the study, especially given the ‘controversies’ associated with urban renewal interventions globally. As far as implementation is concerned, the institutional mechanisms, the cooperative government imperatives and the community perspectives are highlighted and reported on. Lastly, the study also proposed different policy and implementation options, as well as an implementation model. This model is advocated as an option for local government consideration with the aim of resolving the urban renewal problematique.

- Description: In an attempt to manage scarce health care resources and keep drug expenditure low, health care administrators worldwide have to make careful considerations regarding the choice of drugs to be provided to patients within their systems. One of the key strategies that is being employed to achieve this goal is the use of formularies. A major challenge in the formulary development process is to use pharmacoeconomics and outcomes research effectively to arrive at formularies that simultaneously provide patients with effective pharmacotherapy whilst maintaining financial stability. The extent to which this can be successfully achieved depends to a large extent on the availability of appropriate pharmacoeconomic data. The primary objectives of this study were to describe the availability and quality of literature pertaining to South African based pharmacoeconomic research, and to establish the manner in and extent to which pharmacoeconomic data is used in drug formulary decision-making processes, in both the private and public health care sectors in South Africa. A structured bibliographic search for South African pharmacoeconomic studies was conducted and a qualitative assessment of the identified studies which met the predetermined inclusion criteria was completed, using a pre-validated quality evaluation tool. In order to determine the use of pharmacoeconomic data in the formulary decisionmaking processes, by various stake holders in both the public and private of health care sectors in South Africa, a cross-sectional, descriptive study using a self-administered questionnaire was conducted. The results suggest that there is a limited availability of pharmacoeconomic research data in South Africa. Only 16 full pharmacoeconomic studies could be identified as having been published between 01 January 1995 and 30 June 2007. The quality of 3 of these studies was considered to be ‘dubious’, one study was found to be of high standard whilst the other 12 (74.95%) were of acceptable quality and thus could be considered as suitable to be used in formulary decision-making. The results of the national survey indicated that pharmacoeconomics is considered to be of importance and is used in formulary decision-making processes in both the public and private sectors. The primary source of pharmacoeconomic data used in formulary decisions appears to be international peer-reviewed publications. Of concern however, is the finding that this data, mostly from studies conducted outside of South Africa, is applied directly without sensitivity analysis or modelling. The results of the literature search and the subsequent quality appraisal suggest that pharmacoeconomic research and the use of pharmacoeconomic data in formulary decisions is at its infancy in South Africa. Thus efforts are needed to develop and grow the discipline of pharmacoeconomics in South Africa.

- Description: The global threat of climate change is one of the most crucial environmental issues facing the world in modern times. In response to this threat, international governments have drafted the Kyoto Protocol which included the Clean Development Mechanism (CDM). The CDM is a scheme which invited developing countries, like South Africa, to become involved in climate change mitigation projects. While South Africa has been identified as an attractive host country for CDM projects, research has revealed that it lags behind other developing countries in this regard. This study provides a theoretical background to the CDM and grounds the subject within the field of Environmental Economics. Following a literature review of factors that could influence the involvement of a municipality in CDM projects, this thesis undertook a case study of the barriers and drivers to CDM implementation within the Nelson Mandela Bay Municipality (NMBM). Use was made of semi-structured interviews, where a questionnaire was used to guide the researcher’s interview process. Five NMBM officers, who were likely to have been involved with CDM project implementation, were interviewed. Data collected was analyzed using a coding technique and was compared and contrasted to the literature in a process of explanation building. It was possible to elicit 14 factors that acted as CDM-barriers; seven that acted as CDM-drivers; and 10 that were required to change within the NMBM to encourage greater CDM involvement. Of the barriers, lack of awareness, poor political will and lack of funding emerged as the most inhibiting. Of the CDM-drivers, the potential financial benefits; ownership of infrastructure capable of producing carbon assets; and technology transfer emerged as the factors most likely to promote CDM involvement. With regards the factors that require change, it emerged that a positive response would result from a proactive stance by National Government on the CDM; the use of Public-Private-Partnerships to facilitate CDM projects; and improved communication and capacity building within the NMBM and the Nelson Mandela Bay business community. The main recommendation offered to the NMBM was for it to draft a Sustainable Development Policy as well as a formal sustainable development strategy to drive a coherent and consolidated approach to the Municipality’s involvement with CDM projects. Further, it was proposed that the NMBM should, lobby National Government for it to promulgate enabling legislation and a framework which would encourage CDM investment in South Africa; and engage with local business to promote the active involvement of the Nelson Mandela Bay with the implementation of CDM projects.

- Description: The roles that women perform as depicted in African films are often dictated to by the type of society they find themselves in. At first glance traditional societies can be seen as oppressive because of the presence of certain cultural practices. Alternatively modern urban settings appear to offer women authority and empowerment through employment. However, with a closer examination one sees that the situation is not so simplistic. Such is the case when certain traditional practices that are deemed oppressive through a Western perspective, are still found in urban societies. Films on the subject of African women have to be cautious not place their characters in stereotypical roles. Therefore, it is not enough to merely portray African women as ‘oppressed’. African films that engage in a feminist critique need to present ‘realistic’ portrayals of African women. Such characters are layered and complex. The film Faat Kine (2000) depicts such a character in the authoritative protagonist Kine. The film La Vie est Belle (1987) examines the issue of polygamous marriages and patriarchy from the point of view of two African women living in France. Touki Bouki (1973) examines two young characters living in Senegal and questions the possibility of escape from ones circumstances. Traditional practices such as polygamous marriages are explored in Xala (1975), and Finzan (1989) explores cultural practices such as forced marriages and female circumcision. This treatise will consider women and work in both traditional society and urban settings. African feminism will also be investigated for the purpose of exploring common social perceptions of women in Africa.

Wastewater samples from Amalinda, Shornville and Fort Hare wastewater plants, and water samples from Gogogo and Tyume rivers were collected on ice and transported to the laboratory of the department of Microbiology and Biochemistry, University of Fort Hare for processing. The DNA dendograms of Salmonella and the applied UPGMA revealed 4 similarity groups of the strains. Most of the strains recovered from Amalinda, Shornville, Fort Hare wastewater plants, Gogogo and Tyume rivers show a high percentage of genetic similarity. On the other hand, protein dendograms of Salmonella isolates revealed 2 similarity groups which varied widely. Also, the lipopolysaccharide dendograms revealed three similarity groups with the first similarity groups showing a very high relatedness between strains from different water sources. The second similarity group included 16 strains which formed a rather homogenous group, and the third similarity group formed a distinct group. Of the seven antibiotics and sulfonamides tested against the Salmonella species, five namely, neomycin, chloramphenicol, kanamycin, streptomycin and cotrimoxazole were significantly inhibitory, while the bacteria showed considerable resistance to doxycycline and sulphamethoxazole. Our results based on restriction digestion, SDS/PAGE and dendogram construction show that there is a high similarity between the forty Salmonella strains studied, and that these methods are valuable tools for evaluating the relatedness ofSalmonella species. Our observations have proffered a veritable reference point on the diversity of Salmonella strains in the studied area.

- Description: Information technology developments in software and hardware have enabled radical changes in information systems, culminating in the paradigm Business Process Management. There has been a concomitant rise in the importance of information security and security engineering due to the increased reliance by society on information. Information is seen as a critical success factor which needs protection. Information security is the response to increased hazards created through recent innovations in Web technology and the advent of intra and inter enterprise-wide systems. Security engineering is based on a variety of codes of practice and security metrics which aim at ameliorating these increased security hazards. Its aim is to produce a balanced set of security needs which are integrated into the system activities to establish confidence in the effectiveness of the security counter-measures. It is generally accepted that security should be applied in an integrated approach, for example, in Information Systems development. This has proved to be a noble thought but is the exception to the rule. Security, historically, is generally applied as an after-thought in an Information Technology implementation. This motivated the concept of formulating a model of integrating security inherently within the paradigm of BPM. The overarching requirements of the model are to align the overall organisational security initiatives and ensure continuous improvement through constant evaluation and adaptation of the security processes. It is the intention of this research to show that these requirements are achievable through aligning the process management methodology of BPM, with the security paradigms of Information Security Management (using the ISO 17799 standard) and security engineering (using the Systems Security Engineering Capability Maturity Model – SSE-CMM). The aim of the Business Process Security Maturity model as the output of this research, is to link the SSE-CMM, as the security metric and appraisal method, to the ISO 17799 security standard, which provides the guidance for the information security management framework and security control selection, within the Business Process Management environment. The SSE-CMM, as the security version of the Capability Maturity Model, provides the necessary strategy to control the security engineering processes that support the information systems and it maintains that as processes mature they become more predictable, effective and manageable. The aim of the model is to provide an integrated, mature security strategy within the business process and monitor and correct the security posture of the implemented counter-measures.

- Description: The aim of this research project is to conduct an evaluation on the implementation of gender mainstreaming in South African government departments, with specific reference to the Department of Justice and Constitutional Development (DoJ&CD) and the Department of Foreign Affairs (DFA). The research project is based on the hypothesis that despite the existence of a National Gender Machinery, Gender Focal Points (GFPs) face numerous challenges in implementing gender mainstreaming, due to various internal and external factors. Based on the two case studies, the research project concludes that despite a strong commitment from government, GFPs still face challenges in effectively implementing gender mainstreaming. This is due to a lack of accountability, an understanding of the concept of gender mainstreaming, as well as a lack of resources. Furthermore, systemic weaknesses within the National Gender Machinery are exacerbating the challenges faced GFP

- Description: The integration of Information and Communication Technology (ICT) into the curriculum has become the major issue worldwide. The education system does not only pursue the integration of ICT into the curriculum because of its popularity in the market system, but because of the role it is perceived to play in the changing curriculum (encourages active construction of knowledge). According to White Paper 7 e-Education policy (2004:17) every South African learner should be able to use ICTs confidently and creatively to develop the skills and knowledge they need to achieve personal goals and to be full participants in the global community by 2013. The central role played by teachers in teaching and learning requires them to have a holistic understanding of ICT integration. Furthermore they should be able to analyse when ICT integration is appropriate according to what is expected from the learner in the teaching and learning process. Drawing on the evidence from a survey of nine secondary schools in the Grahamstown Circuit of the Eastern Cape, this study examines how teachers from three different types of secondary schools: Former Department of Education (FDET) schools, Former House of Representatives (FHOR) schools and Former Model C (FMC) schools perceive the integration of ICTs in the curriculum. The salient ideas of how teachers perceive the integration of ICTs into the curriculum emerge from what they view as benefits of using ICT and what they view as challenges of integrating ICT into the curriculum. Contrary to expectations, the degree of ICT integration within the curriculum did not correspond directly with the availability of sufficient hardware, software or Internet connectivity at the participating schools.
