  • Description: The study investigated psychological capital as a moderator in the relationship between occupational stress and quality of work life. The study used the explanatory survey research design. The convenience and purposive types of the non-probability sampling method were used to sample 150 male and female healthcare practitioners who participated in the study. Validated questionnaires were used to elicit information from the study’s participants. Four hypotheses were stated and analysed using the inferential statistical approach. The research findings showed that there was a significant positive relationship between occupational stress and quality of work life; there was a significant positive relationship between psychological capital and quality of work life; and there was a significant moderating influence of psychological capital on the relationship between occupational stress and quality of work life. And finally, there was no significant relationship between psychological capital and occupational stress. There is need for managers to focus on the four dimensions of psychological capital to help minimise occupational stress and improve quality of work life of healthcare practitioners. Management was also advised to devise optimal methods to curb stress and strengthen the mental and physical abilities of the employees’ outcomes. Future research should endeavour to apply a longitudinal research design in investigating the extent to which psychological capital can predict occupational stress, and in understanding its influence in the quality of work life of employees. The future study can spread the investigation to other districts as this study was conducted in just one district, which is a foremost limitation of the study.

  • Description: Recent observations have recognised the increasing role of aeolian processes as a geomorphic agent on sub-Antarctic Marion Island. This study presents the first long-term data on aeolian processes and dynamics at Mesrug (46° 56’ 41”S; 37° 49’ 59”E) on subAntarctic Marion Island. An intensive and high-resolution (five-minute interval) environmental monitoring campaign was initiated using Pace Scientific XR5 data loggers while aeolian transported sediments were collected using Big Spring Number Eight (BSNE) sediment traps at four different heights above the ground. The aeolian features at Mesrug is identified as mega-ripples and is essentially an erosional feature, while annual sediment flux at 0.05 m height were calculated as 2.29 kg cm-2 y -1 . Spatial data based on a two-year survey showed that the entire surface of the study area have lowered by deflation while the ripples shifted slightly eastward (down-wind). Furthermore, the site lost 3.4 m3 of sediment between these two surveys with an average of 0.75 cm per 1 m2 across the site which has an area of 454 m2 . The study suggest that the relatively large particle size of surface sediments on Marion Island is a major contributor to the low annual aeolian sediment flux. From the AWS data it is clear that high wind speeds are frequent at Mesrug and the high wind speeds facilitating sediment movement. Sediment supply is the limiting factor of aeolian sediment transport, but even though the perennial wetness experienced on the island is not a major limiting factor to sediment flux, it may influence rate of movement. The predominant wind direction at the study site is from the south-west but maximum wind velocities are from the north-west. The data from the wind-aspirated BSNE sediment traps, indicate that sediment movement occurs closest to the surface and weight of sediment moved as well as size of particles decreases vertically in the air column. It seems that the upper limit of aeolian sediment transport at Mesrug is 0.8 m above the ground and saltation of particles is the dominant aeolian transport mechanism. Sediment movement occur in near gale to gale force winds and horizontal precipitation. This is mainly associated with strong north-westerly winds which are linked to a frontal system from a mid-latitudinal cyclone that has a strong meridional component or is a cut of low pressure. The data suggest that the climate change implication of a reduction in the westerly component of wind could reduce wind speeds and this could influence the magnitude and frequency of aeolian sediment transport on Marion Island in the future

  • Description: Every business has a goal of being profitable which relies on employee job performance. To determine the relationship employee engagement, trust, goal setting, job fit and training had on job performance surveys was sent to 8 MTN Branded retail stores within the Eastern Cape to gather data. Each survey once completed would then be dropped off and the MTN head office in Cape Road. Previous work has looked at these independent variables and how they affect job performance separately and not as a whole. Contrary to the literature, goal settings were the only variable that had a significant influence according to the findings of this study. The statistical results of this study revealed that goal settings influenced job performance with a p-value of 0.010 (p<0.05) and had a positive relationship, indicating that the respondent’s goal settings had an influence on their job performance. The mean values indicated that the respondents agreed that the independent variables would affect the performance. Thus, it is highly recommended that management investigates the requirements of implementing strategies of these variables to improve job performance.

  • Description: Purpose: According to Khan and Khan (2011:56), a trade union is an organization of employee tasked with activities which include negotiating on behalf of their members for “pay and conditions of employment”. Several authors have purported that these roles extend beyond ensuring not only that the rights of workers are not violated and that their working environment complies with health and safety standards, but also that unions may have an effect on management practices, generally and specifically, on efficiencies and performance (Zulu, 2009; McGuire, 2011; & Dhliwayo, 2012). Health care workers including professionals are organised by the unions in a bid to influence social and economic reforms in the South African democracy. The main aim of this study was to examine the role of public sector unions and how they exercise their functions in delivery of health services Method: A qualitative research method based on phenomenological and case approaches was applied. Semi-structured interviews with open ended questions were used to prompt discussions. Documents were used to obtain complementary data. Senior managers, middle managers, union/employee representatives and employees who are members of the unions in the district hospital of Nelson Mandela Bay health district constituted the target population. Purposive non-probability sampling, which was the preferred method for this study, yielded 16 participants. Results Analysis followed Creswell’s thematic analysis involving coding responses categorising them and identifying themes. This followed repeated and thorough listening to the recorded interviews and transcribing. Themes identified were organisational functioning in line with the service delivery context; worker’s rights protection; negotiating better service conditions; implementing legislation, policies and resolutions; union-management interaction; engaging in strikes and impact on services delivery. Conclusion and Recommendations: The study found that the presence of unions in health care services was necessary because there are various categories of employees – working class – whose interests must be served. The role of the unions leaned heavily towards protection of the rights of the workers. As far as the observation of legislation is concerned, the unions demonstrated knowledge of the legislation applicable to the health care personnel, that is, the BCEA, the LRA and the PSA. The study found that unions were a hindrance to health services delivery in their quest to exercise voice monopoly. The unions tended to exert undue influence on management resulting in lack of discipline and dereliction of duty. The strike actions compromised quality of health care and the rights of citizens to access health care. There was no active participation nor positive contributions in committees where advancement of service delivery standards were deliberated and promoted. Recommendations included training of shop stewards; capacitation and training of managers, and development and communication of departmental labour relations policies.

  • Description: Background: HIV/AIDS is a major global public health problem. The higher education sector too, is affected by the scourge of HIV/AIDS. Universities are considered to be high- risks areas for HIV infection because many students indulged in high risky behaviour link to HIV infection; therefore developing ways to prevent students for acquiring HIV and as well reducing HIV prevalence rates through training and teaching about HIV/AIDS will contribute to change in behaviour of students. Anecdotal evidence suggests that the majority of the students at Fort Hare lack the general awareness and education in HIV/AIDS due to lack of information coupled with their general disadvantaged background with the ultimate result being threatened by high infection rates. The University of Fort Hare (UFH), in a bid to capacitate the academic staff in respect of the laudable initiative to integrate HIV/AIDS in curricula, decided to embark on a pilot study that is anticipated to form fundamental strategies to sustainable HIV/AIDS curricula integration across all faculties, at least by the end of 2030. The university has planned to engage in the curriculum integration process by implementing a two year cycle pilot study during the grant period. Aim: The main aim of the study was to assess the challenges faced by students and educators concerning the integration and implementation of HIV/AIDS curriculum at the University of Fort Hare. Methods: The study adopted a quantitative, explorative descriptive design to examine the challenges associated with the Integrated HIV/AIDS curriculum at the University of Fort Hare. The target population was the educators and students who had training and teaching in the Integrated HIV/AIDS curriculum. A purposive sampling was used to select 487 students and 23 educators from across three departments: Nursing Science, LKA (Life, Knowledge and Action) and Law involved in the HIV/AIDS Curriculum Integration programme at the university. A self-design questionnaire was used for data collection focusing on the demographic profiles of the participants, the teaching strategies and methodologies adopted in the Integrated HIV/AIDS curriculum, the usefulness and relevance of the newly integrated HIV/AIDS curriculum content in addressing the needs of the students and the community, and the challenges faced by the educators and students in the Integrated HIV/AIDS curriculum. Ethical approved was obtained from the Research Ethics Committee of the University of Fort Hare. Permission was obtained from the participants through written consent forms. The data was analysed using descriptive statistics (frequency counts, percentage, means and standard deviations (SD)). The Chi-square test was used to examine the relationship between the variables of interest across the departments. A p-value of 0.05 was set for statistical significant testing. Results: The majority of the participants have adequate knowledge of HIV transmission, as 93.2 percent indicated HIV can be contracted through unprotected sex, sharing of needles (92.1 percent), receiving a blood transfusion that has not been screened for HIV (83.9 percent), sharing razor blades that has not been disinfected (83.0 percent), and having more than one sexual partner (86 percent). Age, gender, race and department were significantly associated with knowledge of route of HIV transmission. The present study indicated that the participants experienced several challenges during the teaching of the Integrated HIV/AIDS curriculum. Time allocated was the biggest challenge (58.3 percent), followed by undated materials, and curriculum overloading and teaching. The study indicated that majority of the students would like to compile a portfolio of evidence in the teaching of HIV, followed by creative arts, DVD/movies, and internet research. The majority of the lecturers preferred to teach HIV/AIDS through expressive arts, followed by role play, and formal lectures. The majority of the participants stated that HIV/AIDS information would be useful to them to apply in their communities and in their profession (97 percent), emphasizing that such knowledge and information will empower them to participate in roadshows and voluntary work at HIV/AIDS Shelters. The findings of this study pertaining to the challenges faced by educators during the implementation of the Integrated HIV/AIDS curriculum revealed that the majority of the participants stated that the HIV information was not updated, heavy workload, and adequate training. The lecturers expressed that they would prefer to teach HIV/AIDS curriculum by expressive art through drawing and creating art that expresses HIV and the relevance in the students’ community. Conclusions: Majority of the students received teaching of HIV as part of a course, and HIV teaching as an integrated component in a subject, while few received it as a stand-alone subject offered by a lecturer/facilitator. The present study indicated that the participants experienced several challenges during the teaching of the Integrated HIV/AIDS curriculum. Time allocated was the biggest challenge (58.3percent), followed by undated materials, and curriculum overloading and teaching. The majority of students preferred HIV/AIDS to be taught by their peers experience in HIV, by face-to face by a person who is HIV/AIDS infected or affected. The majority of the lecturers preferred to teach HIV/AIDS through expressive arts, followed by role play, and formal lectures. The majority of the participants affirmed the relevancy of HIV information taught. They further indicated that the information and knowledge gain would able them to make informed decisions on sexual behaviour. The majority of the participants stated that the HIV information was not updated, heavy workload, and adequate training. Most of the educators used formal lectures, followed by compilation of a portfolio of evidence, storytelling, DVD and movies, and experiential learning in hospitals and clinics in teaching HIV/AIDS integrated curriculum. The lecturers expressed that they would prefer to teach HIV/AIDS curriculum by expressive art through drawing and creating art that expresses HIV and the relevance in the students’ community. It is recommended that student’s involvement in the decision making processes of the integrated HIV/AIDS curriculum at the University of Fort Hare would make the programme more successful. HIV/AIDS resource materials need to be updated regularly and relevant to provide educators with specialized knowledge to be able to teach HIV/AIDS.

  • Description: Approximately 2-4 billion cases of infectious diarrhoea occur every year, with the highest numbers recorded in sub-Saharan Africa. It remains the most common public health issue among children in developing nations. The purpose of this research was to unfold the prevalence of diarrhoeagenic E. coli and Campylobacter pathotypes as well as elucidate their antibiogram characteristics in diarrhoeal stool samples collected in some medical facilities in Eastern Cape Province, South Africa. Two hundred stool samples were collected from both inpatients and outpatients from male and females of all age groups attending selected medical facilities in the study area. Isolation and characterization of both organisms were done using culture based and molecular methods. Antibiotic susceptibility patterns of identified isolates were determined against a panel of 12 antimicrobial agents. One hundred and twenty presumptive E. coli isolates and 42 presumptive isolates of Campylobacter spp. Were isolated. Eighty-two percent (82 percent) of the presumptive E. coli isolates were confirmed as E. coli while 46.3 percent belonged to Campylobacter spp. Pathotyping of the diarrhoeagenic E. coli isolates by Polymerase chain reaction (PCR) showed the following prevalences: DAEC 43 (32 percent), EHEC 18 (17 percent), EIEC 11 (10 percent) and EPEC 18 (17 percent). EAEC and ETEC were not detected, while for Campylobacter spp. 37 (88 percent) were C. jejuni, and C. coli was not detected. A total of 12 (32.4 percent) of the confirmed Campylobacter jejuni isolates were found to possess the fliM gene, 9 (24.3 percent) possessed the flhA gene and only 6 (16.2 percent) harboured the gene flgE2. None were positive for the flaA, flab and flhB genes.The antibiotic resistance patterns observed among the E. coli isolates were high against ampicillin (98.1 percent), chloramphenicol (94.3 percent) and tetracycline (90.6 percent). For Campylobacter spp., resistance observed were: chloramphenicol (91.6 percent), tetracycline (25.2 percent), erythromycin (49.6 percent) and gentamycin (56.4 percent). A lesser resistance against imipenem (35.9 percent) and quinolone (ciprofloxacin) (45.5 percent) were exhibited by the E.coli isolates. 10.8 percent and 20.3 percent of the Campylobacter isolates were resistant to imipenem and ciprofloxacin respectively. The presence of chloramphenicol (CatA1) and tetracycline (tetA) resistance genes were detected in 94 percent and 89 percent of E. coli isolates respectively while 98 percent of Campylobacter spp. Harboured the catA1 resistance gene. It could be deduced from this study that E. coli and Campylobacter spp. are predomiant enteric pathogens as the etiologic agents of diarrhoea in the study community, and that their antimicrobial resistance is high in the study location. The need to develop strategies to prevent infection and control resistant organisms is evident.

  • Description: The first section of this paper looks specifically at the concept of greenwashing from a theoretical perspective. It aims to establish exactly what greenwashing is, what it involves and how it has been used. The second section incorporates both the first section of this paper, and delves deeper into how greenwashing has been present in social media. The third section of this paper is a case study. This section has been broken down into three categories of industries in consideration of greenwashing practises. The first is ‘The Obvious’ - this looks at the obvious examples of industries that use greenwashing practises. ‘The Overlooked’ looks at the industries which are often disregarded in terms of greenwashing practises. The last is ‘The Unexpected’ which looks into the industries that focus on supporting the environment and would not commonly be associated with any form of greenwashing practises at all. This case study aims to identify how the selected companies chosen for the study have been associated with greenwashing in the past, and how their current social presence may still be contributing to greenwashed advertising. As the concept of greenwashing is based on a theory developed around two decades ago and mostly consisted of very direct claims and statements using traditional advertising mediums such as billboards and magazine adverts, and considering the amount of well-known corporations who were proven guilty of such greenwashing practises, it would be ignorant to consider that such practises have simply subsided and ceased to occur. Corporations are aware of being called-out with negative press, especially with regards to issues such as false environmental practises, therefore as the advertising industry has changed with time, wouldn’t such greenwashing practises have adapted as well? Corporations in the past have learnt that direct greenwash statements have backfired negatively, therefore in collaboration with the use of social media, the prospect of using subtle, or even subconscious greenwash strategies seem to create an issue which requires investigation.

  • Description: Pitched is a novella made up of short stories. It is about breaking in, breaking down and breaking out of the advertising industry. My protagonist loves and hates this confusing world she lives in. She is tough but also emotional and anxious, often trapped between her strong desires and her strong morality. She finds herself both attracted to and repulsed by the people who inhabit this world - sexy wolf-like men, and prickly female execs alike. I have been inspired by the work of Lidia Yuknavitch, Kate Zambreno, Michelle Tea and Chris Kraus to create a universal woman I can identify with.

  • Identifier: http://hdl.handle.net/10962/420 , vital:19957
  • Description: The kinetic and dosimetric features of the main thermoluminescent peak of synthetic quartz have been investigated in quartz ordinarily annealed at 500_C as well as quartz annealed at 500_C for 10 minutes. The main peak is found at 78 _C for the samples annealed at 500_C for 10 minutes irradiated to 10 Gy and heated at 1.0 _C/s. For the samples ordinarily annealed at 500_C the main peak is found at 106 _C after the sample has been irradiated to 30 Gy and heated at 5.0 _C/s. In these samples, the intensity of the main peak is enhanced with repetitive measurement whereas its maximum temperature is unaffected. The peak position of the main peak in the sample is independent of the irradiation dose and this, together with its fading characteristics, are consistent with first-order kinetics. For doses between 5 and 25 Gy, the dose response of the main peak of the annealed sample is superlinear. The half-life of the main TL peak of the annealed sample is about 1 h. The activation energy E of the main peak is around 0.90 eV. For a heating rate of 0.4 _C/s, its order of kinetics b derived from the whole curve method of analysis is 1.0. Following irradiation, preheating and illumination with 470 nm blue light, the main peak in the annealed sample is regenerated during heating. The resulting phototransferred peak occurs at the same temperature as the original peak and has similar kinetic and dosimetric features, with a half-life of about 1 h. For a preheat temperature of 200 _C, the intensity of the phototransferred peak in the sample increases with illumination time up to a maximum and decreases thereafter. At longer illumination times, no further decrease in the intensity of the phototransferred peak is observed. The traps associated with the 325 _C peak are the main source of the electrons responsible for the regenerated peak.

  • Description: More employees in organisations in the built environment are beginning to suffer from ill health related to work when compared with employees in other industries. There are many reasons for this, such as: unsuitable working conditions, physical demands linked to the occupation and the high proportion of transient unskilled and semi-skilled employees. A study concerning the wellness levels of unskilled and semi-skilled employees therefore contributes to the understanding and improvement of employee health within the industry. The main objective of this study was therefore to identify the wellness levels of employees in the built environment and their perceptions of the extent to which their company provides wellness interventions or strategies. The methodological approach used in this study was within a quantitative paradigm, and a questionnaire was used as a data collection instrument. The findings indicated that the employees engaged in healthy activities and that the organisation encouraged the employees to maintain healthy lifestyles. However, there were areas that required consideration. Specifically, more attention should be given to budgeting for wellness interventions, regular health screenings should take place and more attention to substance abuse is required.

  • Description: Since Namibia gained independence parents have increasingly been seen as equal partners in the education process. The Education Act 16 of 2001 provides for the democratic participation in schools by parents, learners and other education stakeholders through the introduction of regional Education Forums and School Boards in schools Parental involvement in school governance has been widely researched and has become a ‘hot topic’ worldwide, including in Namibia. This study investigated and described parental involvement through the School Board in school governance in a secondary school in Otjozondjupa region, Namibia. The study was conducted within a qualitative, interpretive paradigm. The study employed three data collection tools namely, semi-structured interviews, document analysis and observation. The School Board was made up of parents of different classes and backgrounds, i.e. employed, unemployed, professionals and business persons and with different levels of educational background. These members create a network that represents the voices of parents from different social groups, with different levels of social capital. The different levels of social capital shape the nature of the contributions and interactions on the Board. The study found that in spite of the frequency of interaction between the School Board, parents and the community the School Board is still in a dilemma as it is unable to connect with its prominent source of potential support, such as the business community, due to an outdated view that the school is well-off based on its historic status of privilege. With respect to communications with parents the focus tends to be on the negatives of learners’ behaviour or performance and the task of the parents in this regard. Broadening the agenda of the collaboration to include positive aspects of the child would add to the motivation of parents and open possibilities for new forms of collaboration. The school lacks a well-coordinated system for utilizing the available resources as well as community expertise for the benefit of the school. On the strength of the findings, one of the recommendations is for a more structured program and strategy for the Boards various interactions with the community and parents.

  • Description: Integrated Algae Pond Systems (IAPS) are a derivation of the Oswald designed Algal Integrated Wastewater Pond Systems (AIWPS®) and combine the use of anaerobic and aerobic bioprocesses to effect wastewater treatment. IAPS technology was introduced to South Africa in 1996 and a pilot plant designed and commissioned at the Belmont Valley WWTW in Grahamstown. The system has been in continual use since implementation and affords a secondarily treated water for reclamation according to its design specifications which most closely resemble those of the AIWPS® Advanced Secondary Process developed by Oswald. As a consequence, and as might be expected, while the technology performed well and delivered a final effluent superior to most pond systems deployed in South Africa it was unable to meet The Department of Water Affairs General Standard for nutrient removal and effluent discharge. The work described in this thesis involved the design, construction, and evaluation of several tertiary treatment units (TTU') for incorporation into the IAPS process design. Included were; Maturation Ponds (MP), Slow Sand Filter (SSF) and Rock Filters (RF). Three MP's were constructed in series with a 12 day retention time and operated in parallel with a two-layered SSF and a three-stage RF. Water quality of the effluent emerging from each of these TTU's was monitored over a 10 month period. Significant decreases in the chemical oxygen demand (COD), ammonium-N, phosphate-P, nitrate-N, faecal coliforms (FC) and total coliforms (TC) were achieved by these TTU's. On average, throughout the testing period, water quality was within the statutory limit for discharge to a water course that is not a listed water course, with the exception of the total suspended solids (TSS). The RF was determined as the most suitable TTU for commercial use due to production of a better quality water, smaller footprint, lower construction costs and less maintenance required. From the results of this investigation it is concluded that commercial deployment of IAPS for the treatment of municipal sewage requires the inclusion of a suitable TTU. Furthermore, and based on the findings presented, RF appears most appropriate to ensure that quality of the final effluent meets the standard for discharge.

  • Description: The potato tuber moth, Phthorimaea operculella (Zeller), is a major pest of potato crops worldwide causing significant damage to both field and stored tubers. The current control method in South Africa involves chemical insecticides, however, there is growing concern on the health and environmental risks of their use. The development of novel biopesticide based control methods may offer a potential solution for the future of insecticides. In this study a baculovirus was successfully isolated from a laboratory population of P. operculella. Transmission electron micrographs revealed granulovirus-like particles. DNA was extracted from recovered occlusion bodies and used for the PCR amplification of the lef-8, lef-9, granulin and egt genes. Sequence data was obtained and submitted to BLAST identifying the virus as a South African isolate of Phthorimaea operculella granulovirus (PhopGV-SA). Phylogenetic analysis of the lef-8, lef-9 and granulin amino acid sequences grouped the South African isolate with PhopGV-1346. Comparison of egt sequence data identified PhopGV-SA as a type II egt gene. A phylogenetic analysis of egt amino acid sequences grouped all type II genes, including PhopGV-SA, into a separate clade from types I, III, IV and V. These findings suggest that type II may represent the prototype structure for this gene with the evolution of types I, III and IV a result of large internal deletion events and subsequent divergence. PhopGV-SA was also shown to be genetically more similar to South American isolates (i.e. PhopGV-CHI or PhopGV-INDO) than it is to other African isolates, suggesting that the South African isolate originated from South America. Restriction endonuclease profiles of PhopGV-SA were similar to those of PhopGV-1346 and PhopGV-JLZ9f for the enzymes BamHI, HindIII, NruI and NdeI. A preliminary full genome sequence for PhopGV-SA was determined and compared to PhopGV-136 with some gene variation observed (i.e. odv-e66 and vp91/p95). The biological activity of PhopGV-SA against P. operculella neonate larvae was evaluated with an estimated LC₅₀ of 1.87×10⁸ OBs.ml⁻¹ being determined. This study therefore reports the characterisation of a novel South African PhopGV isolate which could potentially be developed into a biopesticide for the control of P. operculella.

  • 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: This study, evaluating income generating projects was conducted on four projects, of which two are in Middleburg that is forming part of Inxuba Yethemba Local Municipality and another two are in Hofmeyer that is forming part of Tsolwana Local Municipality. Both these municipalities are in Chris Hani District Municipality in the Eastern Cape Province. Two of these projects are bakery projects and the other two are poultry projects. The study was explorative in nature as it was aimed at finding the reasons for the non-sustainability of income generating projects in this district municipality. Both qualitative and quantitative research methods were applied. Both the explanatory and a multigroup post-test-only design research designs were used when conducting this study. This was due to the fact that the researcher was interested in evaluating income generating projects with the aim of finding out what leads to their failure, and also of finding out how can they be assisted to be able to sustain themselves. Five respondents from each project were willing to take part in the study and this led to a total of 20 respondents who participated through answering questions that were asked to them by the interviewers guided by the questionnaire which is appendix A of the paper. The results of the study indicated the following factors as the ones that are contributing to the non sustainability of income generating projects: Lack of market for the products; Lack of passion to volunteer from project members; Unnatural causes like storms, that ended up delaying the implementation of the projects; Minimal support from communities by buying their products mostly on credit or not abiding by credit terms when credit is given; Non payment of the project members; Lack of transport for the projects to transport their products to market. The key recommendation that was made was that another study needs to be conducted to verify as to whether these findings can be generalised to other projects in the same district. Additional recommendations are that project members need to be skilled on an ongoing basis, the funders should avail funding for the payment of the beneficiaries, beneficiaries need to be encouraged to volunteer and participate in all the activities of the project, all stakeholders need to ensure the availability of resources before the projects are implemented, and the projects need to have project committees that are made of knowledgeable people who are committed in seeing to it that the projects are sustained.

  • Description: This treatise investigated mathematical word problems (MWPs) and their implementation in Foundation Phase classrooms. Factors influencing the implementation of MWPs, with specific reference to the teachers and learners involved, emerged. Direct and indirect factors influencing the implementation of MWPs were acknowledged. Student teachers‟ reflections on classroom practices experienced during their teaching practice training period for their initial teaching qualification inspired me as lecturer to embark on my own journey of inquiry and study the phenomenon above. As this study was undertaken in South Africa, the need arose to take into consideration the changes that have occurred since 1994. Observations of how democratic values and desires feature, or do not feature, when engaging with the phenomenon had to be considered. This study also aimed to emphasise inequalities in everyday practice. The discovery of “good practice” (Cooper 2010:170) contributed towards addressing the factors that emerged as influencing the implementation of MWPs. Jansens (2009:170) book Knowledge in the blood presents compelling reasons for disclosing the state of current practice and seeks alternatives to promote the required change in mathematics teaching, with one of the perspectives on mathematics education being the emphasis on implementing MWPs in the Foundation Phase. Teachers often extend their own preferences into practice and emphasise their “knowledge in the blood” as their view of good practice. Learners‟ needs and learner diversity are often overlooked. Learners‟ assessment scores, both nationally and internationally, have revealed more negative facts. These low scores have often been, and often still are, news flashes, contributing to a negative view of teachers and education. In order to address the widespread sentiment that there is “no hope for teachers” (Jansen 2011:19), and to avoid a recycling of negativity, “good practice” (Cooper 2010:170) is key to success. This study aimed to discover hope for teachers and learners.

  • Description: This mini-thesis investigates some of the nineteenth century socio-cultural ideals that have structured a connection between virtuosic aerial skill and bodily aesthetics. It views the emergence of a style of aerial kineticism that is structured from the gender ideologies of the period. It investigates the continual recurrence of this nineteenth century style amongst contemporary aerial dance works and outlines the possible frictions between this Victorian style of kineticism and contemporary aerial explorations. From this observation, a possible catalyst may be observed with which to relocate and inspire a study of aerial kinetics sans the nineteenth century aesthetic component. This kinesiological catalyst may be viewed in conjunction with the theories of ground-based kinetic theorist, Rudolph Laban’s choreutic study of the body in space. Thus, it may be possible to suggest and introduce a possible practical dance scholarship for aerial dance. This mini-thesis includes an introductory choreological investigation that draws on and integrates the disciplines of kinesiology; choreutic theory; existing aerial kinetic technique; musicology; and the physical sciences.

  • Description: This study investigated the planning, implementation and monitoring of sustainability principles in Buffalo City Municipality (BCM), in the Eastern Cape Province. It also analysed how reporting on sustainability principles was done at this municipality. The research was conducted as a qualitative case study that used analyses of documents, questionnaires and interviews to gather data. All respondents were involved with BCM, some as municipal officials in key positions in the different directorates and others as councillors. The study was contextualised within the area of sustainable development at local government level. The focus was on how the mandate of sustainable local development at local government level was met in BCM. The focus was on the planning, implementation and monitoring of stipulations of Local Agenda 21 and sustainability principles. The study focused on the provision of basic services; inter-generational equity; integration of economic, social and environmental aspects; community involvement; institutional capacity building; partnerships, and global links. The study established that Buffalo City Municipality incorporated sustainability in its vision. There was a lack of common understanding of the meaning of sustainability. Sustainability principles featured prominently at the integrated development planning phase but were less explicitly mentioned in the implementation, monitoring and reporting phases. Sustainability principles were subsumed in the developmental goals of the municipality. The study also highlighted the need for a strategy to have an institution-wide implementation of sustainability principles which would incorporate raising awareness about sustainability and its value.

  • Description: Housing provision plays a vital role in meeting basic needs. Dwellings provide the security required for basic functioning and are thus essential for both human development and the alleviation of poverty. This study examines the levels and quality of basic infrastructural service delivery (electricity, water and sanitation) at local government level, focusing on housing. The local government areas studied include Grahamstown Fort Beaufort and Duncan Village. This was done for the purposes of analyzing the effectiveness of the existing housing policy with regard to the adequacy of scale, its developmental logic, implementation and coordination. Justification for basic infrastructural service delivery is based on the Basic Needs Approach [BNA] which forms the cornerstone of the World Bank’s delivery framework. The paper makes use of two methods: firstly, secondary sources are used to provide an impression of the broad policy framework focusing around basic service delivery with housing as the centrepiece. Specific attention is thus given to Integrated Development Plans (IDPs) as this is the level of policy-making responsible for the delivery of these services to communities. Secondly, previously un-analysed data drawn from a household social exclusion survey (2005-2006) conducted in three Eastern Cape municipalities (Buffalo City, Makana and Nkonkobe – representing respectively urban, small town, and rural areas) are evaluated. The data are analysed two ways – graphically and through a regression analysis – to test four hypotheses regarding basic service delivery. Graphical analysis demonstrates that services differ according to housing type and location. It was found that brick houses seem more likely to have better basic services than either shacks or mud dwellings. The results also show that there are inequalities in the provision of certain basic services such as water and sanitation between Duncan Village and Grahamstown. Overall, the results of this study show that government is still faced with major challenges in addressing housing backlogs.

  • Description: This thesis is an investigation of the significance of Mhande song-dance in two performance contexts: the Mutoro ritual of the Karanga and the Chibuku Neshamwari Traditional Dance Competition. In addition, I undertake comparative analysis of the structure of Mhande music in relation to the structure of selected genres of Shona indigenous music. The position of Mhande in the larger context of Shona music is determined through analysis of transcriptions of the rhythmic, melodic and harmonic elements of chizambi mouth bow, karimba mbira, ngororombe panpipes, ngano story songs, game, hunting, war, and love songs. Mhande is an indigenous song-dance performed for the mutoro ceremony, the annual rain ritual of the Karanga. The Mhande repertoire consists of distinctive songs and rhythms used for communicating with the majukwa rain spirits. The rain spirits in turn communicate with God (Mwari) the provider of rain, on behalf of the Karanga. Mhande song-dance is performed exactly the same way in the annual Chibuku Neshamwari Traditional Dance Competitions as in the ritual context of the mutoro ceremony. However, in the context of the Competition, it is used for the expression of joy and as a form of cultural identity. The Competition is a forum in which Karanga songdance traditions such as Mhande, compete with other Shona song-dance traditions such as mbakumba, shangara and chinyambera. I contextualize and analyse Mhande song-dance by using the ‘Matonjeni Model’, which in terms of Karanga epistemology, is culture specific. This Model is grounded in description, interpretation and analysis; the primary methods in my research process.
