- Description: Technology is touted as a solution to problems in education. But is it? I report here on experiences with dropping use of slides in lectures and returning to working on the board. The apparent result is more interactive, engaged classes. Unfortunately there are too many other variables to make the experiences here definitive. The purpose of this paper is to provoke discussion on whether technology is overused in teaching when the goals of improving student engagement and general effectiveness of learning can be met many ways. Technology is not necessarily bad, but making it the starting point risks locking out nontechnological options.

- Description: The majority of learners in South Africa are not native speakers of English, yet English is the dominant language of learning and teaching (LoLT). South African teachers, therefore, have the challenge of ensuring that their learners' literacy skills in English are adequately developed so as to facilitate learning in other curricular areas. This study investigated the way in which two Grade 5 teachers employed at different primary schools in the Eastern Cape province of South Africa taught writing to their English first additional language (EFAL) learners. English is the LoLT at both schools. A qualitative interpretive approach was used to identify factors that shape the ways these teachers handle the teaching of writing. The theoretical framework was informed by Borg's model of teacher cognition (2003) Shulman's conception of teacher knowledge (1987). Data collection methods consisted of interviews, classroom observations and document analysis. In-depth interviews, comprising two semi-structured interviews, two post-lesson informal conversational interviews and one stimulated recall interview were conducted with each teacher. Five of each teacher's writing lessons were observed and audio and video recorded. Samples of learners' written work were also collected. Analysis of the data reveals that the two teachers' beliefs, their experiences as learners themselves and subsequently as teachers, impacted on their pedagogy, as did other contextual factors (including the support they received from subject advisors, time management, and the number and range of learners in their classrooms). It was found that both teachers focused primarily on ensuring that their learners completed their written work so that it could be marked and graded in response to demands from their superiors, rather than on engaging deeply with the processes of writing (brainstorming, drafting, revising etc). Not only does this run counter to the writing pedagogy recommended in the Curriculum and Assessment Policy Statements (CAPS), but it also denies learners the scaffolding needed to help them develop the self-regulation skills needed to become independent writers. These findings demonstrate the need for assisting teachers to shift away from focusing only on learners' performance (testing and grading) towards a stronger emphasis on the process of writing. This would require that teachers develop a deeper understanding of the process/genre approaches to teaching writing advocated by CAPS.

- Description: Publisher version , Biological and physico-chemical factors affecting abundance and biomass of shrimp Palaemon peringueyi were investigated in 2010–2011 in the lower, middle and upper reaches of the freshwater-deprived permanently open Kariega Estuary. Shrimp abundance and biomass ranged from 0 to 88 ind. m−2 and 0 to 4.4 g wwt m−2, respectively. Shrimps were most abundant in the lower reach, and highest abundances and biomasses were recorded in the lower reach in June when salinities were low. The shrimps were almost always absent in the upper reach. Juveniles were found mostly in the lower and middle reaches, whereas adults were distributed in all three reaches. Regression analyses showed no statistically significant relationship for either abundance or biomass of the shrimps with temperature, salinity and dissolved oxygen (p > 0.05). The relationship between shrimp abundance and biomass and vegetation cover was positive and statistically significant (R2 = 0.109 and 0.185, respectively; p < 0.05). Vegetation cover plays an important role in determining the presence, distribution and abundance or biomass of P. peringueyi in this estuary.

- Description: Fatty acid profiles were determined in rocky intertidal suspension-feeders (mussels and polychaetes) and grazers (limpets and sea urchins) on a monthly basis over 1 year to assess potential dietary overlap between consumers occupying the same trophic guild, and any temporal shifts in diets. Both reproductive and non-reproductive tissues were assessed in an attempt to separate influences of food quality with those of life cycle. Relative variability in fatty acids over time could not be predicted from the feeding guild occupied by a consumer, and influential factors of the temporal shifts included both dietary and reproductive dynamics (even in muscle tissues). Species in the same trophic guild occupied separate trophic niches throughout the year, hence minimising competitive interactions regarding food acquisition. Based on overall variation in fatty acid profiles of muscle tissues, the suspension-feeders Perna perna and Gunnarea gaimardi and the grazing limpet Cymbula oculus occupied narrower feeding niches relative to the grazing sea urchin Parechinus angulosus. Our results provide compelling evidence for potentially large changes in the lipid composition of intertidal invertebrate populations over relatively small temporal scales (i.e. month to month), and these have important implications for short-term field collections intended for assessing invertebrate diets.

- Description: Numerous ecological studies have used lipids to determine trophic pathways in aquatic systems, as fatty acid profiles provide time-integrated information on an organism’s assimilated diet. Many of these studies have, however, been based on sample collections with a limited temporal scale. The trophic ecology of pelagic systems has been studied intensively using fatty acid analyses, but very little work has been directed toward benthic communities, with the intertidal being especially neglected. The investigation of trophic pathways within rocky shore communities will help us to better understand system responses to environmental changes. The determination of long term temporal variation of the food web within a community could reveal the type, magnitude, duration and frequency of highly seasonal productivity. Changes in fatty acid profiles through time in primary consumers of intertidal rocky shores are poorly understood, but represent an important step towards a more comprehensive understanding of rocky shore food webs, compared with those derived from snapshot or short-term studies. The aim of this thesis was to clarify the temporal variability in the diets of rocky shore intertidal suspension-feeders (the brown mussels Perna perna and the Cape reef worm, Gunnarea gaimardi) and grazers (the Cape sea urchin Parencinus angulosus and the Goat-eye limpet, Cymbulus oculus) on the south east coast of South Africa using fatty acid profiles, and to investigate the effects of life style (e.g. feeding mode) and life cycle on temporal variations in tissue fatty acid profiles. I had three hypotheses: firstly, that suspension-feeders experience high levels of variability in their diets through time because water quality has the potential to change quickly and drastically, whereas grazers experience less variability in their diets over time since their food sources are more constant. Secondly, the reproductive cycles of the suspension-feeder P. perna and the grazer P. angulosus affect the fatty acid composition of their gonads, with temporal variations in lipid composition reflecting changes in reproduction investment. Thirdly, the total amount of energetic reserves available for reproduction are different for each gender (females allocate more energy to egg production than males allocate to gamete production). To address these aims, fatty acid profiles of suspension-feeders and grazers were investigated over a period of twelve months (from July 2010 to June 2011) at a single site on the south east coast of South Africa. The results showed high variability in the fatty acid composition of both the suspension-feeders strongly related with changes in their food source (suspended particulate material). Furthermore, similar temporal changes in fatty acid profiles of the two suspension-feeders were observed over time, reflecting their common diet and life style. There were some inter-specific differences in the suspension-feeders, likely originating from differences in their particle capturing mechanisms. Grazers showed less variability through time compared with the suspension-feeders, with the limpets being more consistent than the sea urchins. The temporal variability in the sea urchin diets may have resulted from the highly diverse and heterogeneous food sources available to them, whereas limpets may be more selective and have a limited range of diet items. Differences between the two grazer species may have arose from differences in their feeding strategies and intertidal zonation. The fatty acid compositions of gonad tissues in both P. perna and P. angulosus showed temporal variability strongly related to reproductive cycle. Differences in the fatty acid values between females and males were apparent, with females richer in total and polyunsaturated fatty acids than males. Spawning and gametogenesis influenced the variability of fatty acids through time in both species, suggesting the importance of considering the reproductive cycle when studying lipids in rocky shore species. Little evidence of lipid transfer between muscles and gonads was seen, suggesting the importance of direct lipid storage into the reproductive tissues. The influence of diet and life history of intertidal consumers on the temporal variability of their fatty acid compositions is important to understand, as it provides us with a better understanding of the functioning of rocky shore systems. There is an enormous potential for future research in this field of study.

- Description: The subject of the present treatise concerns termination of employment contracts that are effected as a result of an employee’s incapacity on the grounds of ill-health or injury. Every employee has the right not to be dismissed unfairly. The Labour Relations Act, 1995 recognises three grounds on which termination of employment might be legitimate. These include the conduct of the employee, the capacity of the employee and the operational requirements of the employer’s business. However, fundamental to any contract of employment is the obligation that rests on an employee not to be absent from work without justification. The Incapacity Code and Procedure in respect of Ill-health or Injury applicable to Educators is contained in Schedule 1 to the Employment of Educators Act, 1998. In addition there are collective agreements which are the products of collective bargaining that are also applicable to all categories of employees employed in the public education sector. Notably, PSCBC Resolution 7 of 2000 forms part of the subject of our discussion. The Department of Education determined the use of independent Health-risk Managers to provide advice on the management of incapacity leave and ill-health retirement, thereby ensuring objective and impartial evaluation which are largely acceptable to employees and their labour representatives. This is the Policy and Procedure on Incapacity Leave and Ill-Health Retirement in the Public Service. The appointed Health-risk Managers make recommendations to the Head of Department who thereafter implement the recommendations and deal with issues of a case to absolute finality. More importantly, the Policy and Procedure for incapacity leave and ill-health retirement in the Public Service is issued in terms of legislation, that is, section 3(3) of the Public Service Act, 1994 and therefore is not a collective agreement. Under the circumstances, it is not always easy to determine a real dispute and an issue in dispute. Because of this uncertainty arbitrators often found that bargaining councils have no jurisdiction to entertain these disputes, while on the other hand some arbitrators opined that bargaining councils do have jurisdiction In this treatise the general principles of the employment contract, the legislative framework applicable in the public education sector in determining an application for temporary incapacity leave and ill-health retirement and procedural and substantive issues in the termination of employment contract due to ill-health are considered and explained. The legal questions around the issue of discretion exercised by the Head of Department in granting or declining applications for ill-health are also examined. The primary aim of the treatise is to provide a clear exposition of the rather complicated law relating to incapacity due to ill-health and injury in public education.

- Description: This research has been undertaken to empirically test the assumption that it is trivial to bypass an antivirus application and to gauge the effectiveness of antivirus engines when faced with a number of known evasion techniques. A known malicious binary was combined with evasion techniques and deployed against several antivirus engines to test their detection ability. The research also documents the process of setting up an environment for testing antivirus engines as well as building the evasion techniques used in the tests. This environment facilitated the empirical testing that was needed to determine if the assumption that antivirus security controls could easily be bypassed. The results of the empirical tests are also presented in this research and demonstrate that it is indeed within reason that an attacker can evade multiple antivirus engines without much effort. As such while an antivirus application is useful for protecting against known threats, it does not work as effectively against unknown threats.

- Description: False codling moth, Thaumatotibia leucotreta (Meyrick) (Lepidoptera: Tortricidae), presents a significant threat to the South African citrus industry. To limit income loss due to direct larval damage or from fruit rejection due to the phytosanitary status of this pest, additional pre-harvest control techniques are required for Navel oranges, which are known to be susceptible to T.leucotreta damage. A number of Navel orange cultivars have been developed, and differences in female T. leucotretaovi positional preference and susceptibility of cultivars to larval penetration are known to exist. Navel orange cultivars were grouped according to time of maturity (early, mid- and late season). Female T.leucotreta were subjected to choice and no-choice tests with these cultivars, measured by oviposition. Host susceptibility was tested by allowing neonate T. leucotreta larvae to penetrate the different Navel cultivars. In the early maturing group, Fischer Navels were least preferred for oviposition and the least susceptible to larval penetration. The mid- and late season maturing groupings showed limited differences in oviposition preference, although host susceptibility did appear to be an important factor in assessing the vulnerability of fruit to T. leucotreta. Despite being widely planted in South Africa, the mid-season Palmer Navels were highly susceptible to larval penetration, while for the late season cultivars, Cambria and Glen Ora Late were the least susceptible to T. leucotreta. As a result of these laboratory trials, it is recommended that farmers increase cultivation of Fischer Navels as the principal early season cultivar, avoid Palmer Navels in favour of other mid-season maturing cultivars and give preference to the late maturing Cambria and Glen Ora Late cultivars, to limit T. Leucotreta damage.

- Description: False codling moth, Thaumatotibia leucotreta (Meyrick) (Lepidoptera: Tortricidae), presents a significant threat to the South African citrus industry. To limit income loss due to direct larval damage or from fruit rejection due to the phytosanitary status of this pest, additional pre-harvest control techniques are required for Navel oranges, which are known to be susceptible to T.leucotreta damage. A number of Navel orange cultivars have been developed, and differences in female T. leucotretaovi positional preference and susceptibility of cultivars to larval penetration are known to exist. Navel orange cultivars were grouped according to time of maturity (early, mid- and late season). Female T.leucotreta were subjected to choice and no-choice tests with these cultivars, measured by oviposition. Host susceptibility was tested by allowing neonate T. leucotreta larvae to penetrate the different Navel cultivars. In the early maturing group, Fischer Navels were least preferred for oviposition and the least susceptible to larval penetration. The mid- and late season maturing groupings showed limited differences in oviposition preference, although host susceptibility did appear to be an important factor in assessing the vulnerability of fruit to T. leucotreta. Despite being widely planted in South Africa, the mid-season Palmer Navels were highly susceptible to larval penetration, while for the late season cultivars, Cambria and Glen Ora Late were the least susceptible to T. leucotreta. As a result of these laboratory trials, it is recommended that farmers increase cultivation of Fischer Navels as the principal early season cultivar, avoid Palmer Navels in favour of other mid-season maturing cultivars and give preference to the late maturing Cambria and Glen Ora Late cultivars, to limit T. Leucotreta damage.

- Description: Developing countries face challenges in the development of infrastructure and population growth. These lead to “side-effects" such as uncontrolled urbanization and the fact that basic services such as water and sanitation are lagging behind the actual needs on the ground. Historical challenges, lack of skilled staff and often lack of sustained funding are some of the reasons for the status quo. Extent of water and sanitation coverage often forces national and local governments to install the minimum-standard solutions, e.g. the ventilated improved pit latrines. This improves the public health status in the short-term, but causes problem in the long run due to the lack of regular maintenance such as through lack emptying of pits. Sometimes, construction of these facilities is of inferior standard. Pits are often built without lining or zero consideration is given to the local conditions in terms of soil properties, water table and the number of toilet users.

- Description: The present study was conducted to assess selected heavy metal levels (Cu, Fe, Zn, Ni and Pb) in soil and plants that are irrigated by mixed industrial and domestic wastewater in the Buffalo City region. Three types of samples were studied: soil, water and vegetables (spinach and beetroot). Soil analysis showed that most of the heavy metals were found to be acceptable within the SEPA limits. Most of the heavy metal concentrations found in the wastewater indicate that the water is not suitable for irrigation or for livestock use, according to guidelines from the Department of Water Affairs and Forestry of South Africa. The level of copper in the wastewater effluent exceeded the level specified by SEPA limits. In the wastewater the lead concentration averaged 3.24 and 1.98 ppm in Tshatshu (TS) and Mlakalaka (ML) respectively, which shows that both sites are not suitable for both irrigation and livestock usage. The heavy metal levels (Ni, Pb, and Cu) in both spinach and beetroot samples exceed the criteria specified by the WHO and SEPA standards. The study recommends terminating the usage of effluent for irrigation and further investigation or monitoring in these water sources.

- Description: New policy initiatives that followed the 1994 democratic elections aim strongly on construction and development, especially in the agrarian sector. Land reform is one of the initiatives that the democratic government has implemented post 1994 to enable the previously marginalised and disposed individuals and families to own land. The aim of the land reform was not only to provide settlement beneficiaries, but to provide post settlement support to them and enable them to live a better life. However, most of the beneficiaries who acquired farms through the land reform programs lack practical experience in commercial agricultural production. In light of the above, the agricultural mentorship programme was implemented to offer a ray of sunshine to smallholder and emerging farmers. However, it is quite evident that although the agricultural mentorship program was implemented, the Kat river valley emerging citrus farmers are still facing challenges such as limited production capacity; limited access to financial capital; limited access to production equipment; and limited post-harvest support. This study aims to review the agriculture mentorship programme of the Department of Agrarian Reform and Rural Development (DRDAR), with a specific focus on citrus at Kat River Valley. Using data drawn from a sample of nine (9) mentees, two (2) mentors and one official from DARDAR who were personally visited and interviewed, the thesis presents the results of an assessment of the program’s outcomes for participant’s experiences and perceptions in order to strengthen the programme. A review of related literature on land and agriculture reform, agricultural policies, emerging farmers and mentorship has been presented. The study employed a qualitative approach for in-depth understanding and verification. Source documents, open-ended questionnaires and semi-structured interviews were used to collect data from participants. The study revealed that the mentorship programme has made an impact since its implementation as can be noted by the increase in production and income levels; sustainability of skills and knowledge attained from during mentorship and also job opportunities from the projects.

- Description: Maize is the most grown crop by the farmers in Jozini. Therefore, the main objective of the study was to assess the economic impact of climate change on maize production under different farming systems in Jozini Municipality in KwaZulu Natal (KZN). The study was looking at the smallholder farmers producing maize under dryland and irrigation system. A total of 100 farmers were selected for the study (40 from dry-land and 60 from irrigating farmers). Cluster and random sampling procedures were used to select the sample. Questionnaires were used for the collection of primary data, from the respondents (maize farmers). Data was analysed using descriptive statistics (frequency, percentages), gross margin, regression analysis and the Ricardian model. Data for computing gross margins and net revenue was taken from the on-farm trials. Gross margin was used on regression analysis and the net revenue was used on the Ricardian modelThe results of the regression analysis indicated that land size, farmer’s experience to farming, level of education, use of fertiliser, use of irrigation and the yield obtained were significant and have a positive relationship with farmers gross margin. The results of the Ricardian model indicated that climate change affects both farming systems, but farmers that are producing under dryland are the most affected farmers because they rely more on climate variables especially rainfall for their production. So a change in climate variables affects maize farmers’ productivity and thus affecting farmers’ gross margin and net revenue. The study recommends that the farmers must use irrigation in order to support maize production even in the absence of rainfall. Farmers must also adapt to the short growing season so that they will be able to produce even in the presence of climate change.

- Description: This study examines the production of masculinity in the advertisements of South Africa’s two most popular men’s lifestyle magazines, FHM and Men’s Health. I specifically focus on advertisements, as I argue that they play a crucial role in the re‐production of prominent discursive formations. Informed by a poststructuralist framework this study adopts Foucault’s notions of discourse, power and the constitution of the subject. Gender is conceived of within power relations, with a hierarchical relationship between masculinities and femininities. The gendered subject is also viewed as being constantly in process and being constructed performatively through material forms of practice. Focusing on group representations to establish gender hierarchies, I argue that these representations of people are performative acts, hailing the subjects who view them and producing reality through discourse. Hegemonic masculinity, which is argued to be prominent in advertising, is located at the highest point in the gender hierarchy. However, there is not one universal hegemonic masculinity, for it can vary across three discrete political contexts: the local, which is constructed in the immediate face‐to‐face interactions of families, organisations and social structures; the regional, which is constructed at the level of culture or the nation state; and the global, which is constructed in supra‐national locations. In the advertisements of FHM and Men’s Health there is interplay between the latter two as global and regional brands both advertise in these magazines. To investigate the portrayal of masculinities in these publications, this study first undertakes a content analysis to survey the “general landscape” of representation in the advertisements and then performs a critical discourse analysis to uncover “thick description” of the production of masculinity. The content analysis, finds that the advertisements in the sample validate both white and heterosexual forms of masculinity. The sample is comprised mostly of white males, white females and black males, generally proposing forms of hegemonic masculinity, emphasised femininity and complicit masculinity respectively. The representation of white males and black males is different both in terms of the frequency of representations and in the types of representations. I argued that a certain tension inhabits the resulting representations, which try to be inclusive of a multi‐racial South Africa, yet do so within a clearly hierarchical structure. An in‐depth analysis of eight texts, informed by Fairclough’s model of critical discourse analysis and Kress & van Leeuwen’s framework for visual analysis, finds similar results to the content analysis while providing insight into how various discourses produced the representations, particularly within non‐narrative advertisements.

- Description: The South African Constitution provides that a child’s best interests are of paramount importance in every matter concerning the child. This principle emanates from the United Nations Declaration on the Rights of the Child (UNCRC) and the African Charter on the Rights and Welfare of the Child (ACRWC). Accordingly the State and its various departments have adopted and are enforcing legislation and policies in defence of the child’s best interest. The principle of the best interest of the child is seldom observed in most of our schools. Incidents of child abuse are on the increase, especially by educators. This unfortunate situation prevails against the backdrop of legislation which condemns these atrocities. Section 17 of the Employment of Educators Act1 provides that educators must be discharged if they are found guilty of, inter alia, sexual abuse, intimate relationship with a learner and assault with grievous bodily harm. These measures have been taken to combat the vicious cycle of child abuse in schools and to advance children’s-rights agenda and the universal principle of the child’s best interests. For the department to successfully prosecute educator cases against child abuse, the testimony of a child witness is crucial. However, it is shocking to discover that the interests of the child witness are not always served in these disciplinary hearings. Officials are prone to be biased towards their fellow professionals at the expense of the interest of the child witness. This situation normally arises probably as a result of a lack of professional capacity because most of these officials tasked with disciplining educators have a teaching, human-resource or legal qualification. Others may have been recruited from the ranks of the trade-union movement without any formal qualification. Secondly, they may be specialists in the field of labour law which is essentially concerned with the regulating the employer and employee relationship. Thirdly, the disciplinary code and procedures that are used during educator-disciplinary processes are premised on the principles and values of the Labour 1 Act 76 of 1998. Relations Act Code of Good Practice: Dismissal2 and Schedule 2 of the Employment of Educators Act3 which addresses the interest of the child witness to a very limited extend. Finally, the policies regulating workplace discipline are generally biased towards employee rights as espoused in the Labour Relations Act4 and CCMA guidelines on misconduct arbitrations. This study has identified a number of challenges confronting the child witness and also areas of capacity improvement on the side of officials officiating over the disciplinary cases of educators. These challenges form the basis for a comprehensive and consolidated list of aspects in which officials need to be trained to effectively promote and defend the interest of the child witness in a professional manner. The role of the departmental representative in becoming the champions of the democratic Constitution and the vanguard of the child’s best interest cannot be over-emphasised. The question of how best to serve the best interest of the child witness has been addressed. The child witness can be a credible witness provided officials win over his or her confidence to speak out against abuse. The 16 days of activism against women and children abuse has to resonate consciously with departmental officials.

Finally, the policies regulating workplace discipline are generally biased towards employee rights as espoused in the Labour Relations Act4 and CCMA guidelines on misconduct arbitrations. This study has identified a number of challenges confronting the child witness and also areas of capacity improvement on the side of officials officiating over the disciplinary cases of educators. These challenges form the basis for a comprehensive and consolidated list of aspects in which officials need to be trained to effectively promote and defend the interest of the child witness in a professional manner. The role of the departmental representative in becoming the champions of the democratic Constitution and the vanguard of the child’s best interest cannot be over-emphasised. The question of how best to serve the best interest of the child witness has been addressed. The child witness can be a credible witness provided officials win over his or her confidence to speak out against abuse. The 16 days of activism against women and children abuse has to resonate consciously with departmental officials.

- Description: Home- and community-based care is deeply rooted worldwide and is an integral part of the continuum of health care. This form of care ranges from highly technical and professional services to simple forms of non-professional and voluntary support in homes. Currently a large number of people with HIV related illnesses are being cared for at home by their next of kin and community members as volunteer caregivers. With the continued high number of HIV infections, there is a need to initiate more home- and community-based care centres in South Africa. The study in question explored the challenges and coping strategies of care-givers working in home-based care for people infected with and affected by HIV/AIDS. A qualitative research approach has been employed using an explorative, descriptive and contextual design. The sample was drawn from three home- and communitybased care centres in Cofimvaba, in the Eastern Cape. Semi-structured interviews were used for data collection. Data was analyzed according to the Tesch’s model (1990). The strategy of Lincoln and Guba was used to verify data. Findings indicated that caregivers working in home-based care for people infected with and affected by HIV/AIDS, experienced challenges such as: lack of resources for proper caring; lack of cooperation from the beneficiaries of the caregivers who are getting social grants; influence of community perception on HIV infection on home- and community-based care; and emotional strain on caregivers. Relevant recommendations related to the findings are presented.

- Description: The purpose of the study was to investigate the challenges facing the National Youth Service Corps’ (NARYSEC) skills development programme implementation in the OR Tambo District in the Eastern Cape Province. A secondary aim was to determine whether the actual NARYSEC implementation matches the desirable needs of the poverty-stricken unemployed NARYSEC beneficiary participants and their communities. The study, which was framed within Amartya Sen’s Capability and Entitlement Approaches (1985), used multiple data collection instruments – (1) semi-structured survey questionnaire, (2) face-to-face semi-structured interviews, (3) semi-structured telephonic interviews and (4) key expert informant in-depth face-to-face interviews – to collect data from 73 NARYSEC participants and three expert informants (N=76). The study used purposive and snowball sampling strategies in selecting the participants. Data was analysed using thematic data analysis technique and the results suggested that the NARYSEC skills development programme offered to unemployed youth in the resource depleted former homeland districts of the former Transkei of the Eastern Cape Province, did not achieve the NARYSEC objectives and the desirable needs of the NARYSEC beneficiaries and their communities. The evidence suggested that failure of the NARYSEC programme could be attributed to the implementation methods as well repeated cycles of mismatch between the official NARYSEC objectives of recruiting and developing rural youth to perform community service in their own communities and the actual NARYSEC implementation results. The study showed that one of the challenges NARYSEC programme faced was from the poorly structured implementation mechanisms, which were manned by untrained civil servants and not by skills development experts who were capable of implementing the programme successfully. The research findings also seemed to suggest that two of the major factors responsible for the NARYSEC programme failure in the Eastern Cape were the chronic implementation weaknesses stemming from the historical and contextual constraints dating back to the apartheid era. To enhance the NARYSEC objectives and the desirable needs of the unemployed rural youth and their communities, the study suggests the following: Firstly, it was recommended that policy planners and implementers should incorporate the desirable needs and aspirations of the youth and their communities into the NARYSEC programme design and implementation process. This recommendation is informed by the divergence that characterized the NARYSEC programme implementation. Secondly, it is suggested that the NARYSEC Monitoring &Evaluation process must be revamped in order to reverse the general trend of the poor monitoring and evaluation performance that characterised the NARYSEC programme implementation.

- Description: The main aim of this study is to investigate challenges of re-skilling former inmates in South Africa in the 21st century. This is a case study of the Nkonkobe Municipality, Eastern Cape - South Africa. The objectives of this research are: to identify the current skills and education programmes offered by the DCS, to establish perceptions of inmates regarding the role of the DCS in skills training and education, to find out whether the current former inmates feel the support of society, to ascertain the offenders’ education levels, professional skills and job experience before and after prison, to identify the status of the offenders’ rights and rehabilitation programmes, to provide recommendations on ways to cement policy loopholes that have a deleterious effect on the government’s drive to create a whole new world for the ex-inmates and their holding communities. A qualitative research design was used to collect data from the participants in order to obtain in-depth information concerning the perceived impact of the life skills programmes on the behaviour and conduct of former inmates who participated in the programme. The findings reveal that the life skills programmes had an impact on the behaviour of former inmates because the life skills that they had gained from the programme mostly helped them desist from committing the offences that they used to commit. The life skills also curbed their anti-social behaviour tendencies. The factors that contributed to the success of the project included the approaches that the facilitators used to run the project, such as, motivating the inmates in everything that they did and the cooperation between the facilitators, the prison and the community. The findings also reveal that the good team work that occurred between the former inmates, support from the community, as well as the support from the Department of Correctional Services contributed to the success of the project. It was also suggested that the project should include all youths in the community; imprisonment should not be a passport to empowerment. The final suggestion was that the project should include all stakeholders in the community. The life skills projects should target unemployed youths in the communities so that they can gain skills that can help them become self-employed. The study also recommends that the life skills programmes should be implemented in all prisons in South Africa to provide inmates with life skills that can help them face day-to-day life challenges. This study culminates in the realisation that no life skills programmes can be successful in any society if they exclude the core social members who are law-abiding citizens. This is key to ensure that these programmes do not polarise the society due to empowerment being erroneously viewed as a preserve of those who did not abide by societal laws. This would set a wrong precedence that this study seeks to forestall. , Thesis (MSoc) -- Faculty of Social Sciences and Humanities, 2014
