  • Description: This study analyses the housing price volatility in metropolitan areas in South Africa, particularly Port Elizabeth and East London residential housing markets. This study uses secondary statistical data, obtained from secondary sources. The study uses quarterly time series data for the period 1981:1 to 2015:3 giving 139 observations. The data will be collected from different sources. The main sources of data are real estate agencies (Trafalgar, Harcourts and Property24), the South African Department of Trade and Industry (dti) and supplemented by the South African Reserve Bank (SARB) and Statistics South Africa (Stats SA). The study shall use the ordinary least squares (OLS) method to estimate its results. Ordinarily, this is a generalised linear modelling technique that may be used to model a single response variable which has been recorded on at least an interval scale. This method requires that the underlying stochastic processes of the variables are stationary. That is, explanatory variables should exhibit constant means and variances over time. If the stochastic processes are not stationary, OLS produces unreliably significant coefficients. Results showed that household savings, household income and total growth in household buildings (TGH) are statistically significant in explaining changes in house prices. Jointly, all the explanatory variables can account for almost 52% of the changes in the dependent variable. The Durbin Watson statistic showed that there is no autocorrelation in the model. This shows that the model is good. Results from the regression show that there is a negative relationship between house prices and household savings. A one-unit increase in household savings leads to a 0.407 decrease in house prices. This relationship makes economic sense because when households save, there is less income available to buy houses. When there is less income available to buy houses, it would mean there is less demand for houses.

  • Description: Leadership development is very important in business and much is often said about ‘growing’ leaders in business organisations. Leadership development cannot be achieved in one training course or programme, but should rather be an everyday practice of existing leaders. Leader development concentrates on individual leader development, enrichment or attainment of within-person competence while leadership development concentrates on relational development. This paper addresses and outlines how an all-inclusive method to leadership development and succession planning is needed for the employees of the Eastern Cape Treasury. It also looks at the willingness of the existing leadership in government to coach and mentor the youth of today to take on a leadership role when the current leaders exit the market. The head office in Bhisho for the Eastern Cape Treasury has 390 employees and in total, when combined with district offices around the Eastern Cape, there are 454. The questionnaire was sent out to 80 employees and 55 of those were filled and returned to the researcher. The targeted employees were those in the following positions: Administrative Officer, Assistant Director, Deputy Director, Director and Chief Director. The empirical results though showed that Autocratic Leadership and Satisfaction with Compensation Package had no correlation with Leadership development, whereas Organisational Culture, Senior Management Support and Participative Leadership Style showed positive correlation with Leadership development success. Implementing the recommendations might help with improving leadership development in the Provincial Treasury.

  • Description: The tax implications of contributions towards maintenance are not always clear to a typical taxpayer. The duty of support is often the driving force behind the contributions made. Donations, payments made by ‘Blessors’, and child maintenance are fundamental objects of attention in this study, although all maintenance payments are considered from a tax perspective with reference to the Income Tax Act No 58 of 1962. The main aim of the study was to illustrate and analyse the interaction of the rules governing the taxation of maintenance payments. Tax abuse was assessed in relation to the anti-avoidance provisions in effect in the legislation. The results were benchmarked against data relating to Australia. In the social context, a fundamental difference in the systems was observed, and the Australian provision may be considered for possible adoption in South Africa. In the context of tax per se, the study found that the operation of the attribution rules in the provisions in South African tax law pertaining to the taxation of child maintenance renders the provisions adequate.

  • Description: This study is a quantitative study done in selected schools on teachers’ attitudes towards the implementation of inclusive education. Despite efforts to ensure quality education for all learners through inclusive education in South Africa, indications are that many learners, especially those who experience barriers to learning, are still excluded from full access to quality and equitable education opportunities in mainstream schools. Research has shown that the success of inclusive education depends upon teachers’ attitudes. It also shows that attitudes can hinder the progress of the implementation of inclusive education. The paper draws on White Paper 6 which speaks to inclusion of children with disabilities in schools. As the legislative and policy framework for the implementation of inclusive education, White Paper 6 states that “a public school must admit learners and serve their educational requirements without unfairly discriminating in any way”. The study is framed by Ajzen’s theory of planned behaviour, which suggests that an attitude towards behaviour is influenced by past experiences, previous knowledge and newly acquired knowledge. The study reflects findings from a questionnaire circulated to 75 teachers at three selected high schools, using descriptive statistics to analyse the data. Findings showed that there is no relationship between attitudes based on factors, including class size, years of experience, inadequate resource, and lack of adequate training but the main negative influence was found to be lack of support in implementing inclusive education. The conclusion is that there is no relationship between attitudes and the factors identified except lack of support. This research concludes with recommendations to address teachers’ attitudes in order to facilitate the inclusion of learners with special needs in the classroom.

  • Description: Unethical conduct takes root and largely flourishes in environments devoid of compliance with SCM laws, regulations and sound corporate governance values and principles. Ethical conduct is a prerequisite of good governance and sound municipal financial management. Unethical conduct in SCM leads to a loss of public trust and confidence in the management of public affairs. Despite the existence of control and oversight structures and processes for monitoring compliance with ethical standards, norms and regulations in SCM, procurement and contract management processes, BCMM still flouts SCM regulations. This leads to non-compliance with precincts of SCM policy regulations, the MFMA, as well as the Municipal Systems Act (MSA). Lack of adequate and effective control and oversight measures further exacerbates the problem, leading to poor management of procurement systems as well as inconsistencies in the disposal and delivery of services. Effective control and oversight often results in the reduction of waste, eradication of corruption and improvement of municipal financial performance, as well as improved ethical conduct, integrity, transparency and accountability. Qualitative approach was used to gather data using interviews and secondary sources in the form of official documents to explore the extent to which control and oversight measures for ethical conduct in Supply Chain Management are effective in Buffalo City Metropolitan Municipality. The data is to be analysed using content analysis and filtering techniques. Challenges that are affecting the effective management of Supply Chain in Buffalo City Metropolitan Municipality were brought forth and recommendations to improve Supply Chain Management in Buffalo City Metropolitan Municipality are examined in this study.

  • Description: The study aimed at examining how strategies used to manage conflict between students and staff in secondary schools in Malawi were implemented. This was after it had been noted that conflicts in secondary schools in Malawi usually ended in violence. The study employed a pragmatic research paradigm. In this paradigm, a researcher employs mixed methods approach which collects both quantitative and qualitative data. Using a concurrent triangulation mixed method design, the two types of data were collected concurrently and analysed simultaneously. Study participants were head teachers, teachers, students, education officials and parents. Most of the teachers were randomly sampled while a few other teachers, the head teachers, the education officials and the parents were purposefully sampled. The study found that there were various causes of conflict in secondary schools in Malawi which included misunderstanding of human rights, poor communication between students and staff, poor school management by head teachers and lack of students‘ involvement in decisions that concerned them. The study further found that conflict was in a way beneficial to schools as it was a learning point for both students and staff. However, such benefits were overshadowed by the many evils that violence brought such as disturbing teaching and learning. The study also found that there were two approaches in the way schools managed conflict; engagement of students and calling for police intervention. It transpired that on the overall, stakeholders were aware of different conflict management skills but they did not know how best to use them. In addition, it transpired that stakeholders were not comfortable with win-win approaches to conflict management. This was against a background that the stakeholders were involved in conflict management in different ways. It also came out clear that support to secondary schools in the management of conflict was at two levels; school level and system level. On the part of monitoring, it transpired that the mechanism which were there were ad hoc and they included inspection visits and the requirement that head teachers should always submit reports which could carry issues related to conflict. The study concluded that poorly managed conflicts which turned into violence were a menace to secondary schools in Malawi. In this regard, there was need to ensure effective conflict management in order to avoid violence. To achieve this, the study has made a number of recommendations. Among them, it has been recommended that schools should from time to time take stork of the likely causes of conflict and address them accordingly. It has also been recommended that schools should put in place mechanisms for ensuring two way communication so that students feel free to air out their concerns. At Ministry level, it has been recommended that the MoEST should take guidance and counselling seriously by among other things training teacher councillors and making the post an established one. It has also been recommended that the MoEST should make sure that head teachers, deputy head teachers, teachers, parents and even education officials are inducted in conflict management.

  • Description: Mature students and their experience of tertiary education is an area of career psychology in which there is currently a lack of research. In particular, little published data related to the transition experience of mature students into and from tertiary education is available internationally and there is even less literature examining these students within the African and South African context. This study contributes to psychology‟s broad body of knowledge as it explores the perceptions of previously employed final year South African students on their transition experience into and from tertiary education. The researcher utilised a qualitative research approach. A non-probability purposive sampling strategy was employed and semi-structured interviews were conducted with five participants. All participants were considered to be mature students in their final year of university study. Interviews were conducted until data saturation was reached. The data obtained was subjected to thematic content analysis using Tesch‟s model. Lincoln and Guba‟s model was used to assess the trustworthiness of the data obtained. The findings revealed several factors influencing mature students‟ entry or re-entry into tertiary education. Participants‟ experience of tertiary education was enriching on both a personal/career level and participants were confident in their abilities. Furthermore, it was found that transition towards a new career starts during their tertiary study and that relying on experiences of their previous job aided them in their transition from tertiary education to new career. Limitations of the study, recommendations for further research and contributions of the research were identified.

  • Description: Enhanced coastal altimetry, adaptive Leading-Edge Subwaveform(ALES), was used to study wo well known eddies along the southeastern African coast, namely the Delagoa Bight Lee Eddy and the Durban Lee Eddy. I address a two part problem. Firstly, how well does the application of coastal altimetry techniques behave in the coastal region? Secondly, is there a relationship between the eddies’ presence and chlorophyll-a (chl-a). Sea level anomalies (SLA) were computed from the re-tracked ALES data of two satellite missions — Envisat (used for Delagoa Bight eddy) and Jason -2 (for the Durban eddy) with geophysical corrections removed. These datasets were compared with the original satellite, 1 Hz RADS, AND AVISO gridded data. Two regions were selected to see if there was a biophysical link. A centre region of the eddy and an outside region of the eddy were taken. Results indicate that coastal altimetrywas successful in delimiting both features. ALES was less noisey and able to recover more data that were missed by the 1 Hz RADS dataset. Hovmöller plots showed the Delagoa Bight eddy to be more of a transient feature than semi-permanent, as had previously been suggested. Results from the linear model indicate a negative correlation between SLA and chl-a. This influence could be through facilitation of chl-a in the bight or just retaining chla. This is hard to elucidate without in situ data. These results show a promising indication that coastal altimetry will be a useful and reliable product to further biophysical coupling research along the coast.

  • Description: South Africa has in the recent past seen employees embarking in strike action, even in sectors designated as essential services. The impact adversely affected inter alia economic growth, investor confidence, international credit ratings and the high rate of unemployment. The Labour Relations Act 66 of 1995 from its inception on 11 November 1996, and as amended, in 2002 and in 2015, has brought about some minor changes to the model aimed at regulating essential services, maintenance services and minimum services agreements. This research is aimed at investigating; whether essential services, maintenance services and minimum services agreements are designed to unjustifiably limit the right to strike or not. The Constitution1 and the Labour Relations Act, 19952 encourages parties in employment relationship to engage in collective bargaining. Mechanisms such as a no duty to bargain envisaged within the current LRA regulatory framework, appears to be undermining the significance of ensuring that parties engaged within services designated as essential and maintenance services exercise their fundamental right to strike and to bargain collectively. The Essential Services Committee when dispensing with its statutory functions may be unjustifiably limiting the right to strike for employees engaged in essential and maintenance services. Some employers may be to some degree reluctant to trigger maintenance services provisions as the LRA appears to be adopting a voluntarism principle when regulating collective bargaining, as the Act is encouraging employers to deal with the provision of maintenance services within collective agreements. An introduction of a judiciable enforceable duty to bargain collectively in services designated as essential and maintenance services may compel employers to conclude minimum services agreements. The extremely low number of services designated as maintenance services is a worrying reality and the solution is urgently required.

Developmental and reproductive performance of a specialist herbivore depend on seasonality of, and light conditions experienced by, the host plant

  • Description: Host plant phenology (as influenced by seasonality) and light-mediated changes in the phenotypic and phytochemical properties of leaves have been hypothesised to equivocally influence insect herbivore performance. Here, we examined the effects of seasonality, through host plant phenology (late growth-season = autumn vs flowering-season = winter) and light environment (shade vs full-sun habitat) on the leaf characteristics of the invasive alien plant, Chromolaena odorata. In addition, the performance of a specialist folivore, Pareuchaetes insulata, feeding on leaves obtained from both shaded and full-sun habitats during autumn and winter, was evaluated over two generations. Foliar nitrogen and magnesium contents were generally higher in shaded plants with much higher levels during winter. Leaf water content was higher in shaded and in autumn plants. Total non-structural carbohydrate (TNC) and phosphorus contents did not differ as a function of season, but were higher in shaded foliage compared to full-sun leaves. Leaf toughness was noticeably higher on plants growing in full-sun during winter. With the exception of shaded leaves in autumn that supported the best performance [fastest development, heaviest pupal mass, and highest growth rate and Host Suitability Index (HSI) score], full-sun foliage in autumn surprisingly also supported an improved performance of the moth compared to shaded or full-sun leaves in winter. Our findings suggest that shaded and autumn foliage are nutritionally more suitable for the growth and reproduction of P. insulata. However, the heavier pupal mass, increased number of eggs and higher HSI score in individuals that fed on full-sun foliage in autumn compared to their counterparts that fed on shaded or full-sun foliage in winter suggest that full-sun foliage during autumn is also a suitable food source for larvae of the moth. In sum, our study demonstrates that seasonal and light-modulated changes in leaf characteristics can affect insect folivore performance in ways that are not linear.

  • Description: The need to incorporate recycled materials in building products is becoming more important than ever before. There is an abundance of waste rubber tyres which in turn results in a waste management issue. The use of waste rubber tyres in cementitious building material provides a possible solution to the problem (Kathomi, 2009:10). Previous research has shown the introduction of recycled rubber tyre crumb can improve the durability, thermal and acoustic performance in residential and commercial buildings. This could result in lives of dwellers in concrete block buildings in South Africa improving due to these characteristics whilst potentially creating a cost-effective, sustainable building material. A grading analysis, loose and compacted bulk densities and relative densities were determined to provide a mix design. Three tests were conducted for this study namely compressive strength, fire and thermal performance and acoustic performance. The testing was conducted on 100mmx100mm cubes at varying rubber replacement percentages. The replacement values were 10%, 20% and 30% tested against a control of ordinary concrete. The waste rubber crumb was a replacement for sand. The research of this study showed 20 % decrease of compression strength at 10 % rubber replacement compared to the control, 55 % decrease at 20 % rubber replacement and 75% decrease at 30 % rubber replacement. The thermal performance test showed a 24 % lower temperature for 10 % rubber replacement compared to the control, 39 % lower temperature at 20 % rubber replacement and 52 % lower temperature at 30 % rubber replacement. All rubber replacement % samples and the control performed adequately in the flame resistance test. The smoke density test showed that all rubber replacement % samples did not release a quantity of smoke which would be deemed dangerous. The acoustic performance test showed the values at 10% rubber replacement was 6 % lower; at 20% rubber replacement; 4% lower and at 30% rubber replacement 14 % lower. Based on these results, the acoustic performance regarding transmission increases with a rubber replacement % higher than 20 %.

  • Description: Three fused-ring-expanded rubyrins with modified macrocyclic core have been synthesized and characterized. A series of spectroscopic, electrochemical measurements and a set of theoretical calculations demonstrate that the core-modification of the inner core of rubyrins has a large influence on the electronic structure. Colorimetric changes are observe that demonstrate that these core-modified rubyrins could be used as selective Hg2+ ion sensors. These properties can be fine-tuned by introducing lipophilic substituents on the meso-aryl rings.

  • Description: The purpose of this research is to investigate the tectonic poten¬tial of Eucalyptus. This is done by using the design of a furniture manufacturing facility in Hogsback as a scenario through which the tectonic potential of Eucalyptus can be explored. Eucalyptus as a material for investigation was chosen because, in the context of South Africa, Eucalyptus is listed as an invasive alien species which poses certain ecological problems to our ecosystems. Yet it is known as a versatile building material. The research is qualitative and empirical in nature and takes the form of pure research. The research was done by conducting site visits and through exploratory artworks and tectonic models (sculptures), as well as by reviewing relevant literature and conducting precedent studies based thereon. It was found that the tectonic potential of Eucalyptus rests in the ma¬terial’s great structural strength, compared to its weight. The factory type proved to be suitable building type through which to investigate the tectonics of Eucalyptus given its functional and architectural concern regarding structure and tectonics. The context of Hogsback added depth to the architectural challenge in requiring a response to climatic conditions, which can vary with vast extremes and can change within a short period of time. The practical implication of this research is that Eucalyptus has great potential in the making of architecture. It therefore warrants further investigation into the material’s structural properties which, thus far, has not been widely researched. This has become more of a necessity due to the fact that it is increasingly becoming more popular as an alternative to commercial species such as pine or other wood species used in the building construction.

  • Description: This study examines how the implementation of CAPS Life Skills curriculum training (as a recontextualising process) is engaging teachers in environmental education. The research was centred on training manuals for Life Skills (Official Recontextualisation Field) and their use in CAPS training at district level in two Eastern Cape sites of recontextualisation (Professional Recontextualisation Field). During the training, teachers developed lesson plans that were reviewed and group interviews were conducted on the training process and its outcomes. The manuals, training process, lesson plans and interview transcripts were analysed for evidence of environmental education, notably content, teaching and learning methods and assessment strategies. Bernstein’s (1990) framework of the pedagogic device underpins this study. Here the concept of the relay is key for tracking the "relay” of the content, teaching and learning methods and assessment strategies through the processes of recontextualisation into the lesson plans for the field of production. During the process of de-location and relocation, gaps are created and this study sought to track and probe patterns of omissions that took place during the relay process in two cases of training. The review of the in-service training course process of recontextualisation and its cascading approach exposed challenges of omission as it became clear that at each level of the recontextualisation process, gaps were apparent. The study highlighted how the 3-5 day workshop process reviewed was not a robust model for professional development. It was not effective and changes in the mode of delivery and processes of support that reach into curriculum practice in the context of the school are recommended. The study concludes that there is a need for continuous professional development as teachers need ongoing support especially for a "new” curriculum like CAPS that is content driven.

  • Description: It is common for countries to adopt growth-targeted strategies to address poverty and as a result, achieve development. South Africa is not an exception and that is the reason for implementing the industrial development zone (IDZ) programme, intended to achieve growth through exports. As part of this programme, the country established five IDZs, each of which operates in specific investment sectors. The economy of the Eastern Cape is experiencing difficulties in terms of unemployment, low wages and a declining population and the migration out of the Eastern Cape is due to limited job opportunities and low wages. The four largest economic sectors in the province are manufacturing, construction, agriculture and mining. The Coega IDZ (CIDZ) is located in the Eastern Cape Province of South Africa and operates in six investment sectors, namely automotive, agro-processing and aqua farming, chemical manufacturing, business process outsourcing, energy and metals. This research investigated the contribution of the CIDZ as a tool for development in the Eastern Cape and South Africa. It further investigates its contribution to the development of the Eastern Cape in the event of its expansion across three additional investment sectors, namely electronics, clothing and furniture. With the aim of conducting a proper assessment of their contribution, the strengths and weaknesses of these three investment sectors were elucidated. Additionally, the research described the operation of four special economic zones (SEZs), namely the Zarqa Free Zone, the Jebel Ali Free Zone, the East London Industrial Development Zone (ELIDZ) and the Coega Industrial Development Zone (CIDZ). The research methodology used was that of a descriptive study (literature-based). The research revealed that there is a need to add these three investment sectors to the CIDZ in order to develop the Eastern Cape, as they have the potential to meet the challenges that the province is facing. The research led to a number of recommendations inspired by the SEZs presented in the descriptive study, to improve the contribution of the CIDZ to the development of the Eastern Cape.

  • Description: Competencies represent the knowledge, skills and attitudes required for job roles. Organisations need to understand and grow competencies within their workforce in order to be more competitive and to maximise new market opportunities. Competency Management is the process of introducing, managing and enforcing competencies in organisations. Through this process, occupational competencies can be assessed to see if candidates match the required job role expectations. The assessment of competencies can be conceptualised from two perspectives. The rst is `competency frameworks', which describe competencies from a high-level overview. As such, they are regarded as theWhat" element of competency. The second perspective is `competencybased learning', which focuses on addressing competencies from a more detailed, task-oriented perspective. Competency-based learning is regarded as the How" element of competency. Currently, there is no available tool that can map the What" with the How" element of competency. Such a mapping would provide a more holistic approach to representing competencies. This dissertation adopts the topic map standard in order to demonstrate a holistic approach to mapping competencies, specially in network security. This is accomplished through the design and evaluation of a Design Science artefact. In this research process a topic map data model was constructed from mapping the `What' and `How' elements together. To demonstrate the applicability of the model, it was implemented in a Computer Security Incident Response Team (CSIRT) recruitment scenario. The aim of this demonstration was to prove that the topic map could be implemented in an organisational context.

  • Description: In this study, for the first time, an electro-driven microextraction method named electromembrane extraction combined with a simple high performance liquid chromatography and ultraviolet detection was developed and validated for the quantitation of zolpidem in biological samples. Parameters influencing electromembrane extraction were evaluated and optimized. The membrane consisted of 2-ethylhexanol immobilized in the pores of a hollow fiber. As a driving force, a 150 V electric field was applied to facilitate the analyte migration from the sample matrix to an acceptor solution through a supported liquid membrane. The pHs of donor and acceptor solutions were optimized to 6.0 and 2.0, respectively. The enrichment factor was obtained >75 within 15 minutes. The effect of carbon nanotubes (as solid nano-sorbents) on the membrane performance and EME efficiency was evaluated. The method was linear over the range of 10-1000 ng/mL for zolpidem (R2 >0.9991) with repeatability (%RSD) between 0.3 % and 7.3 % (n = 3). The limits of detection and quantitation were 3 and 10 ng/mL, respectively. The sensitivity of HPLC-UV for the determination of zolpidem was enhanced by electromembrane extraction. Finally, the method was employed for the quantitation of zolpidem in biological samples with relative recoveries in the range of 60-79 %.

  • Description: The research seeks to assess the efficacy of the oversight role of portfolio committees of Parliament with specific reference to the Portfolio Committee on Public Works between 2010 and 2015. The Portfolio Committee on Public Works has an overarching oversight role over all infrastructural and maintenance services rendered by the Department of Public Works. The Department of Public Works fulfils a pivotal function in the infrastructural and maintenance service rendition to all departments in the executive. This function overlaps on provincial and local government spheres. The researcher dwells much on the capacity and competency of members of portfolio committees and support staff in their use of oversight tools, inclusive of the Theory of Change, Monitoring and Evaluation, Budget Cycle Model, Public Sector Oversight Model and Logical Framework when conducting oversight within a financial year. The critical point that was noted was the inadequate time allocated by the Joint Programme Committee for committee oversight and the inadequate capacity of members and support to apply the instruments designed for effective and efficient oversight. The dearth of application of appropriate instruments for oversight is exacerbated by the proliferation of executive government departments, which stretches the work of the Portfolio Committee of Public Works without stretching the resources. The research methodology used included data collection using questionnaires and interviews as instruments for assessment. Questionnaires were distributed to all Whips of all parties in Parliament. A sample size was measured from the total number of members of Parliament less ministers and their deputies and officials. The sample was fifty members. After analysis of the data, it transpired that the responses on the questionnaires gave a convincing result confirming some assumptions that triggered the research. The researcher arrived at conclusions and thereafter suggested recommendations. The research reflected on weaknesses and achievements of the portfolio committees in their oversight role and stressed the importance of the application and use of oversight-related tools and models in order to achieve best practices for developmental results.
