  • Description: This study employs the panel cointegration and Pooled Mean Group technique to examine the effects of economic growth on greenhouse emissions using the panel data from the period of 1970 to 2014 for five Southern African Development Community group of countries. The increase in the combustion of burning fossil fuels has become the global threat in environmental quality. The Environmental Kuznets Curve hypothesis postulates that at the primary stages of industrial economies there is more extracting of natural resources and more agricultural activities taking place as a result the waste generation and resource depletion accelerate. However, as the economic development improves more, the curve reaches a threshold where it starts to decline due to the increase in economic growth and the change to information-based industries. Based on the empirical evidence, the variables of this study were found to be stationary at first difference and integrated of I(0) and I(1) using Im, Pesaran & Shin W-stat, Fisher ADF, and Levin, Lin & Chu panel unit root test. The existing long-run relationship between the variables were found in both the Pedroni and Kao cointegration test and were significant at 5% in finding the relationship between the variables. The Pooled Mean Group demonstrated mixed results in the study’s regressions, monotonic relationship was found between carbon dioxide and economic growth. The strong existence relationship between economic growth and energy consumption was found to be significant at the 1% level. These results are in line with the EKC hypothesis, which assumes that as the income level increases the society will start to be environmentally friendly and the technology advancement will decrease the emission of pollutants. In addition, in finding the causal relationship between variables, the researcher used the Granger causality test, with the results from this test revealing a unidirectional and bidirectional relationship between all the chosen variables. These results are important for policy makers.

  • Description: Aim: The purpose of the study was to assess the quality of patient care in the Primary Health Care (PHC) facilities of Mnquma Sub-district with the goal of improving or maintaining quality nursing in the area. Methodology: This study followed a quantitative research approach and it is descriptive in nature. The study involved 561 participants, of whom 406 participants were from urban clinics and 155 were from rural facilities, all these participants were attending clinics at Mnquma Sub-district. A structured questionnaire was used for data collection, since the participants were able to read and write in either English and or IsiXhosa. The data was analyzed with the help of a statistician using Statistical Package for Social Sciences (SPSS) program, software for windows version 21.0 Results: Results showed that participant’s responses to five of the twelve items on patient safety were found to have significant associations with residential setting. Rural participants were less likely to disagree with statements on availability of signage at the entrance of health establishment that indicates times when various services are offered, availability of the security guards to ensure patient safety, warning signs always put in place when the floors are wet, availability of at least one toilet for disabled patients in the health establishment and the fact that health professionals are always wearing name tags. This means that patient safety and security is practiced and implemented at the rural facilities according to the national core standards. The findings of the study confirmed that 13 items out of 19 under care and attitudes were found to have significant associations with residential setting. The items were patients spending less than 2 hours in the health facility; staff treating patients politely, illness being explained clearly to the patients, and ability of the patients to ask questions about their illness. Other items included nursing attitudes during opening and closing times of the health establishment, staff responding well when requested to assist, patients are being treated with empathy, patients are addressed by names and patients are being given all the treatment that they need, nurses explains the treatment side effects, and explains how to deal with side effects. This means that responses to these items depend on whether the patient is from a rural or urban clinic. Rural communities were found to be vi less likely to disagree with statements as compared to urban communities. This means that nurses are compliant with nursing care and attitudes in rural clinics. Findings of the study with respect to facility cleanliness, shows that there is no significant associations between the responses to the items which are: surroundings of the clinic are free of unpleasant smells, grounds of the clinic are clean, safe and clean grounds, bin waste inside and outside storage poses no health risks, and setting were detected. This means that the facilities are and cleanliness status remains the same across the residential settings. However, the younger age group was found be significantly more likely to disagree that toilets are clean and odorless and that grounds are safe and clean compared to the older age group. This suggests that the environment is clean except the toilets. Conclusion: Staffs at the facilities are at times ignorant and have negative attitudes at the opening and closing times and facilities have been reported to have long waiting times. The study indicated that the safety and security measures in the urban health facilities are not all practiced according to the National Core Standards checklist/Assessment tool, particularly wet warning signs, disabled toilets, and wearing of nametags. Majority of the participants indicated that, the status of cleanliness was on par at the urban and rural facilities.

  • Description: Freshwaterbodies are often recipients of a wide array of infectious agents yet they serve as immediate sources of water supply. Brackish and freshwater rivers support the growth of Vibrio species, which are the leading cause of diarrheal infections in the world. Their occurrence in these environments is detrimental to the health and well-being of many communities. Hence, this study aimed at assessing the occurrence and antibiogram profile of Vibrio species in Swartkops, UMzimvubu and Buffalo rivers. The rivers are important sources of freshwater supplies for some communities around the Eastern Cape Province, and water samples were collected once off from each of the sites, using standard membrane filtration method to concentrate the samples. Cultivation was carried out on Thiosulfate Citrate-Bile Salt Sucrose (TCBS) agar, were typical yellow/green colonies were enumerated as presumptive Vibrio species and expressed as CFU/100mL. Presumptive Vibrio counts ranged from 0 to 1.67 × 103 CFU/100mL, 0 to 6.42 ×102 CFU/100mL and 0 to 3.28×103 CFU/100ml in the uMzimvubu, Swartkops and Buffalo rivers respectively. Polymerase Chain Reaction was employed for molecular identification of the Vibrio isolates. Two hundred (200) presumptive Vibrio species were screened for molecular identification, and 185 isolates confirmed positive as belonging to the Vibrio genus. Antibiotic susceptibility profile of the confirmed isolates was determined using a panel of 12 commercial test antibiotics. All the confirmed Vibrio species showed 98 to 100percent multiple antibiotic resistance against all the test antibiotics from the three study sites. The most predominant phenotypic pattern of multidrug resistance displayed by the isolates was CAZ-PEN-AMP-CIP-AK-AZM-TET-CAM-CTX-STX-GEN-IPM showing 100percent resistance to all 12 antibiotics. The multiple antibiotic resistance index (MARI) on average was 1 for all the three rivers assessed. This finding suggest high possibility of antibiotic pollution and usage around the study areas, and occurrence of potentially pathogenic Vibrio species carrying antibiotic resistant genes, which is a major public and environmental health concern.

  • Description: The declining matric pass rates in the Eastern Cape Department of Education emanate from the ineffective implementation of performance management systems. Using an extensive documentary review analysis, the study explores various challenges which affected the Department in implanting performance management systems to enhance leaners’ performance and improve the work of public officials. The study recognizes that the manipulation of recruitment systems, ineffective leadership and administration discourage the effective implementation of performance management systems. In this case, public officials delayed to sign performance agreements which resulted in low staff morale. The Supervisor in the ECDoE could not provide feedback in time to officials which resulted in low morale. The study revealed the lack of monitoring and evaluation of performance management systems is due to lack of skills in the department. All these challenges affected the department negatively in terms of improving performance management for the benefit of learners’ education in the province. The study concludes that the implementation of skills development programmes in the Department can spearhead effective service delivery. The government of South Africa needs to channel adequate funding towards skills development, which is imperative in the running of an efficient public service.

  • Description: The main aim of the research study was to review the Mhlontlo Municipality Local Economic Development Strategy as a driver of economic development. The Mhlontlo LED Strategy was developed in 2007 to guide economic development of Mhlontlo Local Municipality. The Constitution of the Republic of South Africa (Act 108 of 1996), the White Paper on Local Government (1998), Section B, the National Framework for LED in South Africa (2006), and other pieces of legislation gave direction in the development of LED Strategies in South Africa, including the Mhlontlo LED Strategy. An in depth study was undertaken to review the Mhlontlo LED strategy using document analysis to look at the relevance of the strategy to the current economic activities, its alignment to the current national and provincial development plans. The LED Strategy is no longer aligned to the current development plan, the National Development Plan. It was clear during the study that the Mhlontlo LED Strategy was never understood by both councilors and officials, not working in the LED department and that led to the neglect of the LED strategy in the development plans of the various departments in the municipality. This had adversely compromised the development corridors identified in the LED strategy. The recommendation is that the LED Strategy be holistically reviewed, so that it can be aligned with the National Development Plan, the Mhlontlo Local Municipality Integrated Development Plan 2017-­2021 and other municipal documents. Both Mhlontlo municipality councilors and officials should be trained on the role of the LED strategy in development taking place in the municipality.

  • Description: South Africa‟s liberal democratic constitution allows for political competition for office, enhanced by the media‟s involvement or role, as both stakeholder and facilitator for debate between the public and political parties. The role of the media becomes a sensitive one as it entails perspectives on the political process and, as a consequence, certain perceptions of the political class, structures and electoral process will emerge. In previous elections the media has been cited for abdicating its objective stance in the narrative on political competition in view of candidate lists, party coalitions and allocation of value through cadre deployment, a term used for political appointments within party structures to positions of leadership in public office. Accordingly, it provokes intense debates in which the rationality of liberal-objective-observer to democratic process is criticized by thinking which argues that such rationality remains trapped by a devotion to „liberalist rituals‟, rituals detached from embedded meanings specific to South Africa‟s socio-political dynamics.

  • Description: The Department of Education, as part of the public sector, employs educators in terms of the Employment of Educators Act (EEA),1 whereas the rest of the public servants are employed in terms of the Public Service Act (PSA). If an educator is absent for more than 14 consecutive days without the permission of the employer, the educator is deemed to be discharged according to section 14(1)(a). With regard to the rest of the public sector, a similar provision is put in place, where section 17(5)(a) provides for the discharge of a public officer who is absent from his / her duties without the permission of the Head of Department for a calendar month (31 days). Sometimes long absent periods are caused by personal circumstances of the employee which are unforeseen. If the employee reports for duty after the dismissal, section 14(2) of the EEA provides that, the employee may be reinstated by the employer on good cause shown, after a post-dismissal hearing. If an employee in the public sector is discharged based on these deeming provisions, the employment is terminated by the operation of the law and there is no dismissal. This means that the employer is not responsible for the termination, meaning than there exists no option to review the dismissal. The supreme law of the Republic of South Africa (RSA) is the Constitution of the Republic of South Africa (the Constitution).5 The question at hand is whether the deeming provision of section 14 of the EEA6 is constitutional. The Labour Relations Act (LRA) goes further by stipulating that every person has the right not to be unfairly dismissed, and not to be subjected to unfair labour practice.7 Section 23 of the Constitution provides that everyone has the right to fair labour practices. Furthermore, section 33 of the Constitution provides for fair administrative action. The question is whether these provisions, dealing with the dismissal of educators, limit the employee’s constitutional right to a fair labour practice.

  • Description: This research has five important objectives. First, to outline the legal frame work regulating the right to strike. Outlining this legal framework is important in that it will provide an understanding of both the right to strike and the concept of a protected strike. it is crucial to understand what a protected strike is because the concept underlies the entire research. Without understanding it, it will be impossible to answer the main research question. Second, to investigate the causes of violence during protected strikes. An examination of the causes of violence enables the study to suggest possible solutions to end violent strike action in future. After all the LRA envisages in section 1, labour peace and an effective resolution of disputes. Third, to examine how the LRA regulates the use of violence during protected strikes. An understanding of how the LRA regulates violent strike action is important since the LRA is an important piece of legislation which governs South African labour relations. It is important to obtain guidance on how the law regulates such conduct. Fourth, to ascertain the courts’ approach towards violence during strikes The courts’ approach helps us understand how the courts will deal with strike violence during 5 protected strikes. It is also noteworthy that case precedents in this regard will be of importance when faced with similar acts of violence during strike action. Fifth, to examine the legal implications of violence during protected strikes. This objective directly answers the main research question and this will enable the study to offer possible recommendations in the final chapter of this study.

Ideas of poetic form: aspects of the Romantic-Symbolist tradition

  • Authors: Oldert, David

  • Identifier: http://hdl.handle.net/10962/54554 , vital:26587
  • Description: The subject of the work is some of the formal and technical developments of modern poetry in the Romantic-Symbolist tradition. These developments were stimulated partly by the ideas of the non-intellectual Symbol inherited from the Romantics and the idea that poetry could be a musical medium inherited from some of the French Symbolists. Their combined influence led to a number of technical problems in the structuring of imagery and the handling of syntax. The work begins, therefore, by tracing the philosophical assumptions behind the ideas of the Symbol and of the musical analogy. I then go on to examine two of the difficulties that these ideas produced. One is the tension between the analogical structure of a poem’s imagery and its metaphorical texture: quite simply, the more compressed and complex a poet’s metaphors become, the more they tend to disrupt the poem’s structure of imagery. The other problem is obscurity, which is caused by insufficient objectification of private images in a symbolic structure, and by fused metaphor, which is essentially a metaphor with an obscured ground of resemblance. Finally, I show how these difficulties were solved by poets outside the tradition who used a more articulate kind of syntax, yet who also managed to combine that syntax with the ideal of symbolic form. The implicit argument, then, is that the Romantic-Symbolist ideas of form, and the New Critics’ theories of form which were largely based on them, are able to elucidate an essentially different kind of poetry, and thus have some degree of truth and use beyond the tradition that generated them.

  • Description: Integrative Summary In 1997 the Minister of Public Service and Administration of South Africa, Zola Skweyiya, introduced the White Paper on Transforming Public Service Delivery(Department of Public Service and Administration(DPSA,1997: 1). It was premised on what was called Batho Pele (DPSA, 1997: 9), giving effect to Section 197 of the Constitution, Act 108 of 1996 as amended. A linkage to performance management can be found from the assertion made in the White Paper that in future the Batho Pele would form the basis of any assessment of the performance of individual staff and that would contribute to improving the delivery of service (DPSA, 1997:16). Another factor that contributed to the utilisation of a performance management system was the recommendation put forward by the Public Service Commission of South Africa( PSC,2004: 16),that called for public institutions to adopt a clear, comprehensive performance management and evaluation framework for the delivery of public service. That was expected to turn around the ailing public institutions whose record of serving the public with pride and dignity was on the decline. The research aim was to evaluate the effectiveness of the performance management system in creating and resolving role conflict with health professionals employed by the Buffalo City sub-district. The research goal was divided into three objectives, namely: evaluation of the effectiveness of the performance management system as a managerial tool for health managers to manage their subordinates including both professional and support staff, evaluation of the effectiveness of the performance system from the perspective of the health professional as a subordinate and to analyze the functioning and effectiveness of the system in creating and resolving role conflict between professional conduct and organisational requirements. The respondents noted that the implementation of the system was not matched with appointment at managerial level with officials having relevant managerial capacity. Further to that resources at the coal face of service delivery continued to deteriorate and became very scarce and there is no documented proof that has been found of an effort made to check the compatibility of the system to health professionals. The literature identified negative effects that have emanated from the implementation of the performance management system. The study was conducted by interviewing health professionals from the entry level to the management level within the Buffalo City sub-district from three mini hospitals or Health Care Centres. The respondents indicated that there are positives that have been achieved by the implementation of the system, such as the skills gap identification as well as specific targets contained in annual performance contracts. These targets help motivate health professional to focus on that particular direction of activities. Unfortunately it has been clearly documented that the performance management system has also contributed to the development of role conflict in a number of professionals. It has been documented that the system has not been crafted with a health professional in mind and, as such, appears to favour quantity rather than quality of health services as advocated by the codes of practice of different health professionals. There are a number of recommendations that were put forward by the respondents to try to salvage the system and in mitigation of the identified negative factors. For the improvement of the system, the Eastern Cape Provincial Department of Health has to firstly customise the annual contracts to contain only the fundamental information. Secondly need to improve the transparency pertaining to financial pressures facing the Health Department. Thirdly the provision of essential enablers, need to be prioritised. Fourthly there is a need to upgrade the system to incorporate 360 degree feedback. Further research recommendations include a bigger sample incorporating different research methods and to also incorporate searches for measures that can be implemented to improve the system to be more relevant to health professionals. This document is organised and presented in three sections. The first section is the evaluation report with a review of literature, research methodology, findings, discussion and conclusion. The second section is where an indepth literature review is located and the last section details the research methodology.

  • Description: A novel electrospun nanofiber colorimetric probe for the detection of Alkaline Phosphatase (ALP) for diagnosis of liver toxicity was developed through electrospinning of a para nitrophenyl phosphate (pNPP) functionalised nylon polymer. The chemical stability of the enzyme substrate (pNPP) and its two products (para nitrophenol (pNP) and para nitrophenolate (pNPL)) was evaluated in biological (pH 7.4), acidic (pH 2) and alkaline (pH 9) pH, respectively. Enzyme kinetics models of Michaelis Menten (MM) and Lineweaver Burk (LB) were used to characterise free ALP. Solution and nanofiber assaying of free ALP and 10x diluted serum (spiked with ALP) was also carried out. The results demonstrated that pNPP and pNP were colourless while pNPL was yellow which indicated that all reagents were chemically stable. In addition, the chromophore of pNPL exhibited a strong molar extinction coefficient (ε) of 18,458 M-1 cm-1. LB plot being the most accurate compared to MM showed Vmax, Km and excess substrate concentration of 5.5 × 10-3 μmol/min-1, 0.025 mM and 0.25 mM respectively. Solution and nanofiber assaying of free ALP and serum confirmed a direct proportional correlation between the pNPL yellow colour intensity and enzyme activity up to 858 IU/L and 820 IU/L respectively. The dipping of the nanofiber layer into solution showed that the leaching rate of pNPP was extremely high at 1.37 × 10-3 A/min-1 as was observed after only the first 0.25 min interval. However, this was not of great concern since it was also observed that administration of the sample (20 μL) by a dropwise method minimised leaching compared to dipping. The preliminary findings on the effect of temperature on the chemical stability of pNPP indicated that it was stable below temperatures of 40°C while it hydrolysed at 80°C. Therefore a sensitive, rapid and simple colorimetric probe for the detection of ALP was developed. The probe exhibited characteristics that make it suitable to be incorporated into point of care colorimetric liver toxicity diagnostic devices for applications in resource poor settings and telemedicine.

  • Description: Teenage pregnancy is an important health and social problem in South Africa. Despite declining trends of fertility rates in last two decades, the pregnancy among school girls remains steadily high in South Africa. Teenage pregnancy had negative impacts on various aspects of socio-economic well being of school girls. Aim: To determine the proportion of teenage pregnancy among high school girls and to identify the possible factors that influence teenage pregnancy in Mthatha region during the year 2009. Materials and Methods: This is an observational cross sectional, analytic study of teenage pregnancy conducted among high school teenage girls in the Mthatha region of South Africa. Result: A total of 1150 teenage girls from 15 to 19 years of ages responded from seven high schools in the Mthatha region of South Africa. In total 113 (10%) of teenage high school girls were currently mothers or had previously been pregnant. The proportions of those who had ever been pregnant increased significantly with age. The risk of falling pregnant among public high school teenage girls had two times higher compared to private high school teenage girls. Condoms were the most common method of contraception whereas the oral pills were the least common in practice. About half of teenage girls who had ever been pregnant had an abortion and of this one-third had had a backstreet/illegal abortion. The frequency of substance use was significantly higher among teenage girls who had ever been pregnant. A significant correlation was found between low socio-economic status, public schools and teenage pregnancy in this study. Conclusion: Teenage pregnancy is common among high school girls from 15 to 19 years of age in the Mthatha Region, South Africa. Poor socio-economic family conditions, lack of contraceptive use, early sexual maturation, risky behaviour, lack of knowledge about sexuality and reproductive health, multiple sexual partners and substance use were the common contributing factors of teenage pregnancy.

  • Description: The introduction establishes the goal of the research, which is to discover that art concerned with re-evaluating the relationship to the environment and spirituality can serve to connect people to one another, and to the environment. The context of the research is the contemporary ecological and spiritual crisis of the postmodern world. The background places the discussion within the contexts of modernism and postmodernism. The historical background focuses on the period from the 1960s to the present day. Land and Environmental artists who work in a manner that is conscious of environmental issues and who suggest a sacred and creative attitude to ecology are discussed. My own creative work which is a response to both ancient and contemporary sites as well as to contemporary theories of art and spirituality is discussed. The four projects, are discussed in chronological order, they are: Quest - A journey into Sacred Space; Gaika's Kop - Sacred Mountain; Labyrinth - Journeys to the Centre; and Transforming the Centre. The conclusion shows that the multi-faceted, intertextual and relativistic philosophy of postmodernism has brought about a significant change in the attitude of humanity towards the environment. Artists who reject the modernist aesthetic and philosophy are making art that emphasises relationship to, rather than separation from the natural world.

  • Description: This thesis looks at what choice of medium of instruction (MOl) parents in a rural village in KwaZulu would make if they had the opportunity to choose. The background to this choice goes back to 1979, when Education and Training Act No. 90 established the mother tongue as MOl from Sub A to Std 2 in Department of Education and Training (DET) primary schools, followed by a sudden transition to English medium of instruction - (EMl) in Std 3. Though by 1990 98% of the schools had opted for EMI, conditions were not favourable for a sudden transition and the policy led to high drop-out rates. The problems encountered by teachers and learners were researched and documented by Macdonald in the Threshold Project Reports (1990). Although the Minister initially ignored the Project's findings, in May 1991 he admitted that his department's language policy was leading to serious educational disadvantages. The explosive situation that culminated in the 1976 school uprisings led to the amendment of the Act. There was concern among people involved in educational language policy that parents had not been given sufficient information to make informed educational choices. They feared that many parents would, largely out of ignorance, opt for straight-for-English, when in fact the conditions in the schools were not conducive to the success of that choice option. The widespread assumption about the parents choosing straight-for-English was based on anecdotal evidence. I decided to investigate this matter in the Nongoma area. My findings pointed to very healthy attitudes towards the mother tongue and there was even a measure of understanding of the place of mother tongue instruction in the beginner classes. But even though the respondents wanted their language to be respected, they also wanted their children to acquire a good education in English, so as to be eligible for jobs in an economy that emphasises the importance of English.

  • Description: An investigation is made into the mathematics behind the noniterative inversion algorithm of Shimon Coen and Michael Wang-Ho Yu [1981]. The algorithm determines the conductivity profile of a horizontally uniform earth from surface measurements of apparent resistivity with a Schlumberger array. The algorithm is checked by performing the inversion on both artifical and raw field data

  • Description: The idea of generalising the classical notion of the inverse of a non-singular matrix arose as far back as in 1920, but it was not until the late fifties that the development of the theory gained any impetus. Since then , as is the case in the development of many new concepts , work done in parallel in various parts of the world has resulted in a great deal of untidiness in the literature : confusion over terminology , and even duplication of theory. More recently, however, some attempts have been made to bring together people active in the field of generalised inverses, in order to reach consensus on some aspects of definition and terminology, and to publish more general works on the subject. Towards this purpose, a symposium on the theory and application of generalised inverses of matrices was held in Lubbock, Texas, and its proceedings published in 1968 (see [25] ). A few other works of this nature (see [4], (19a] ) have appeared , but the bulk of the literature still comprises numerous diverse papers offering further ideas on the theoretical properties which these matrices have , and drawing attention to their application in areas of statistics , numerical analysis , filtering , modern control and estimation theory, pattern recognition and many others. This essay offers a look at generalised inverses in the following way: firstly a broad basis and background is established in the first three chapters to provide greater understanding of the motivation for the remaining chapters, where the approach then changes to become far more detailed. Within this general framework, Chapter 1 offers a brief glimpse of the history and development of work in the field. In Chapter 2 some of the most significant properties of these inverses are described, while in Chapters 3 and 4 and 5 attention is given to interesting and remarkable computational algorithms relating to generalised inverses (some well suited to machine processing). The material of Chapters 4 and 5 is largely due to Decell, Stallings and Boullion, and Tanabe, in [6], [24] and [27], respectively, while the source of material for the first three chapters is the literature generally, with Penrose's two papers providing a rough framework for Chapters 1 and 2 (see [17]).
