  • Description: Orientation: The constant subjective criticism by the public for poor and or a total lack of service delivery by government departments in terms of meeting requirements and standards and the non-performance seem to rest with the public employees. In government, work engagement leads to the satisfaction of the citizens or clients, which in turn leads to the citizens trusting and having confidence in public organisations. Research purpose: This study aimed at examining the mediating role of job autonomy between mobile technology usage, work engagement and emotional exhaustion amongst public service employees in Bhisho. Motivation for the study: There is growth in the usage of mobile technology in Africa. However, the effects of mobile devices on the working environment are still unclear. A research gap exists on the effects of mobile technology on employee outcomes such as work engagement and emotional exhaustion. Research approach/design and method: This study used a quantitative approach, with a descriptive and explanatory research design. Analyses were conducted by SPSS 23 and Amos 22 on a sample of 165 public service employees. Main findings: The results show that mobile technology usage improved work engagement of the employees through their job autonomy. Mobile technology usage did not have any significant effect on the employees’ emotional exhaustion and work engagement. Practical/managerial implications: The findings from this study imply that mobile technology can result in positive psychological experiences for employees and present some managerial implications for boundary conditions. Contribution/value-add: This study contributes to the literature on mobile technology usage, work engagement, emotional exhaustion and job auto

  • Description: Worldwide, there is a large body of research that convincingly demonstrates the benefits of Higher Education (HE) in the socio-economic status of individuals who have gone through and qualified with certificates, diplomas and degrees. But access to HE does not just benefit individuals, it also has benefits for communities or broader society (access to HE may benefit individual scholars, but can also benefit economically the entire families and poverty stricken communities such as those from Tsholomnqa village where this study was conducted). However, in South Africa, there is limited research that focuses on the importance of and challenges of access to HE as confronted by rural scholars. This research presents findings from a mixed method based study which sought to probe key issues relating to access to HE and challenges facing rural scholars regarding access to information on HE. The study involved as many as 209 Grade 12 learners from two high schools in the rural area of Tsholomnqa village in the Eastern Cape Province, a province associated with high levels of poverty, inequalities and unemployment in South Africa. The findings reveal that rural scholars about to qualify for university access information on HE information primarily from the internet. However, it was found that issues such as not having data or smartphones to search the internet and lack of support from their parents and teachers including universities affected their self-efficacy and self-esteem. The implications of these findings suggest that HE institutions must target and strengthen outreach and visibility in rural schools.

  • Description: The research investigated the impact of leadership on performance in the case of selected schools in Mthatha district in the Eastern Cape. The research used a mixed method methodology combining qualitative and quantitative methods. The sample size was N=60 using purposive sampling. The dependant variable in the research was the school performance and the independent variable is the good leadership. The questionnaire was analysed quantitatively from a total key respondent of 45 leaders in the different schools.15 school educational leaders were interviewed and analysed qualitatively using thematic analysis. Research findings indicated that there is still male domination in school leadership positions over females. The leadership composition is 53percent males and 47percent females in Eastern Cape. School leadership positions are, in general, held by long serving members who are former teachers with a higher degree of seniority than the young school leaders. This is typical of traditional Xhosa societies dominated by elders in decision making. 73percent of the responses show a democratic leadership style when investigating how school leaders manage schools. The second most common leadership style is situational at 66percent, and the least prevalent management style is autocratic, which includes less than 10percent of the respondents. 60percent of the schools are performing and 40percent are underperforming, but overall there is good leadership in schools despite very poor results evidenced in the past 5 years. The research shows a strong correlation between the schools that had good performance and those that had good leadership in which the dominant leadership style was 'bureaucratic' and 'situational'. The schools that had poor results that were underperforming also showed trends of poor leadership.

  • Description: This study involved evaluating the extent to which universal access to quality grade R was realised by 2012 in Cofimvaba education district in the Eastern Cape Province. The evaluation was done through the implementation of goal 11 of the Education Sector Strategy - the Action Plan to 2014, revised to 2019. It further sought to find out whether universal access to grade R occurred to all learners who registered for grade 1 and whether the quality of grade R had improved between 2010 and 2012 in Cofimvaba education district. Improving the quality of grade R in this study included an assessment of the level of qualification of grade R practitioners and an improvement of the quality of grade R tuition through the use of textbooks, workbooks and resource packs supplied to grade R by the Department of Basic Education (DBE). The study used both the qualitative and quantitative methods. Questionnaires were used as data collection methods from grade R practitioners and grade 1 teachers. The respondents in this study consisted of twelve grade R practitioners, ten grade 1 teachers and two officials from Cofimvaba district office. The findings of this study revealed that the universal access to grade R, calculated from grade 1 learners who received formal grade R, was not achieved over the three-year period 2010-2012; albeit the target of grade 1 learners who should have received formal grade R by 2012 was a mere 50 percent. The percentage of grade R learners who received access to the required textbooks fell below the expected target of 100 percent. Although 77.61 percent does not signify bad performance, the non-attainment of 100 percent access to the required textbooks could not be acceptable because the absence of textbooks meant that effective teaching and learning could not have taken place. However, these findings uncovered that the supplied textbooks and workbooks were high quality learning and teaching materials. The findings also uncovered that the ECD-grade R practitioners, at the time, had the necessary work experience and limited qualifications as a means to teach the grade R classes. A pressing matter for the Department was the improvement of conditions of service for practitioners; their professionalisation as well as further improvement of their qualifications. It was revealed, through this study, that there was a slight improvement in the universal access to grade R; however, the quality of grade R still needed attention especially in so far as the provision of suitably qualified practitioners is concerned.

  • Description: The high sensitivities of modern radio telescopes will enable the detection of very faint astrophysical sources in the distant Universe. However, these high sensitivities also imply that calibration artefacts, which were below the noise for less sensitive instruments, will emerge above the noise and may limit the dynamic range capabilities of these instruments. Detecting faint emission will require detection thresholds close to the noise and this may cause some of the artefacts to be incorrectly detected as real emission. The current approach is to manually remove the artefacts, or set high detection thresholds in order to avoid them. The former will not be possible given the large quantities of data that these instruments will produce, and the latter results in very shallow and incomplete catalogues. This work uses the negative detection method developed by Serra et al. (2012) to distinguish artefacts from astrophysical emission in radio images. We also present a technique that automates the identification of sources subject to severe direction-dependent (DD) effects and thus allows them to be flagged for DD calibration. The negative detection approach is shown to provide high reliability and high completeness catalogues for simulated data, as well as a JVLA observation of the 3C147 field (Mitra et al., 2015). We also show that our technique correctly identifies sources that require DD calibration for datasets from the KAT-7, LOFAR, JVLA and GMRT instruments.

  • Description: Self-efficacy in clinical performance is a very important aspect in quality of health care, because it is the ability of the person to produce the desired outcomes. The aim of the study was to evaluate self-efficacy in clinical performance of NIMART programme by professional nurses in Buffalo City Metropolitan in Eastern Cape Province South Africa. A quantitative, descriptive survey design was used to examine self-efficacy in clinical performance during implementation of NIMART programme. A purposive sample of 358 NIMART programme trained professional nurses was included in the study. Analysis of the finding was done using SPSS version 21.0. Descriptive statistics (frequencies, percentage, mean and standard deviations) were used to analyse categorical variables. To reduce data volume, factor analysis was used to identify six variable clusters: Evaluation; planning, assessment, implementation, and patient care mentoring. Factor 1 (evaluation) was highly loaded on patient driven results (0.63); nursing interventions (0.70); breakdown point location (0.80); prognosis based care decisions (0.79); prognosis based outcome monitoring (0.70); and prognosis based settings adjustment (0.70). These items collectively define evaluation of self-efficacy clinical performance of the participants. Factor 2 (planning) was termed planning of patient care in a clinical setting was significantly loaded on these items: data driven nursing diagnosis (0.51); patient driven nursing diagnosis (0.52); settings based nursing diagnosis (0.49); overall care plan formulation (0.52); short-term patients care formulation (0.58); long-term patient care formulation (0.66); goal based measurable outcomes (0.80); goal based daily patient care plan (0.79); settings based daily patient care plan (0.73). Factor 3 (assessment) which was termed assessment in clinical performance was not significantly loaded in some of the items: physical assessment (0.64); patient history (0.65); energy restoration (0.56); time management (0.71); objective patient health data (0.61); subjective patient health data (0.49); data collection documentation (0.44). Factor 4 (implementation) data source correlation; patient health data analysis (0.45); patient strength (0.46); nurse-patient/family communication (0.55); nurse patient collaboration (0.64); Experience driven decision making (0.58). Factor 5 (patient care) patient care plan adherence (0.65); setting based overall patient care (0.74); resource based overall patient care (0.59). Factor 6 (mentoring) patient’s concerns identification (0.48); patient problems prioritisation (0.46); mentor/colleague advice (0.43); mentor/colleague feedback use (0.61); patient discharge strategies (0.71); continuous reporting/documenting (0.63). The mean scores produced by the Kruskal-Wallis test showed the lowest scoring pattern as follows: 20122013201120142010. This order was the same for all the variables, confirming that the 2010 group scored significantly higher than any other group on all the variables. The overall results of the study revealed that professional nurses have high self-efficacy in clinical performance in implementation of NIMART programme, except in evaluation aspect of self-efficacy where they scored lessor. Professional nurses trained by FPD scored higher in the aspects of self-efficacy in clinical performance compared to RTC trained; but scored lower in evaluative ability of self-efficacy in both institutions (FPD and RTC). The findings of this study showed that the overall self-efficacy of the professional nurses trained on NIMART programme performed clinically satisfactorily. It is recommended that in-service education or continuous professional development for professional nurses working in PHC’s should not only concentrate on updating clinical skills, but also create opportunity for reflection and strengthening of professional nurses’ self-efficacy in clinical performance. Also, further study on other processes of goal realisation will aid our understanding of self-efficacy in achieving the desirable goals of the professional nurses for patient quality care. Further research is also needed to evaluate clients’ satisfaction during care based on the NIMART intervention programme.

  • Description: In South Africa, the Constitution, 1996, the Municipal Structures Act,1998 (Act 117 of 1998), the Municipal Systems Act, 2000 (Act 32 of 2000) and the Municipal Finance Management, 2003 (Act 56 of 2003) place municipalities at the forefront for providing basic services such as waste management, electricity, water, sanitation, roads and transport to the communities. The journey that the local government sphere in South Africa has taken over the last 22 years has not gone smoothly, in some respects it has been a bumpy ride one. A single, unified local government had to be established from the fragmented, undemocratic, unaccountable and racially divided local government system that was inherited. The constitutional and political structure of local government, its promise of democratic accountability, and the delivery of services to improve the lives of citizens has proven to be challenging in their implementation. Performance management was introduced in the local government sphere to improve performance by establishing a rational planning process based on the assumption that “business methods” would be more effective than traditional public administration approaches. There is a problem with municipalities such as the BCMM; the problem is that they operate their WSDP, SDBIP, IDP, budget and PMS in silos. The WSDP, SDBIP, IDP, budget and PMS must be aligned so that BCMM can be able to deliver basic services like water and sanitation. The study sought to review the Water Services Development Plan and Service Budget Implementation Plan Alignment with the Performance Management System in Buffalo City Metropolitan Municipality. Data was collected using interviews from a sample of participants comprising mainly of managers of the BCMM, revealed that most of the performance targets set in the financial years 2009 to 2015 were not achieved. The study came up with the following recommendations that there should be regular workshops, training of BCMM officials in the importance of the alignment of the WSDP and SDBIP with the performance management system in the BCMM. The PMS should contribute in the improvement of productivity, through achieving set targets and goals as planned. The processes must be fully integrated. Challenges facing BCMM in terms of alignment must be addressed. There is also a need for sound annual plans with targets (quarterly) that show how the annual targets will be achieved.

  • Description: The turbulent economic and political situation that has plagued Zimbabwe over the past two decades has had a dire effect on its urban population. The country’s tempestuous situation has not only threatened urbanites’ access to basic necessities but has also rendered many households and particularly female-headed households vulnerable to poverty and deprivation. Thus the primary objective of this study was to analyse and understand how coloured female-headed households in Sunningdale, Harare, Zimbabwe are surviving in the context of the current economic and political crises in the country. Essentially the study sought to achieve the three main objectives. The first objective was to identify and document the current livelihood strategies that a small sample of coloured female-headed households have adopted; the second was to explore the challenges and problems faced by female-headed households in their daily lives and lastly, the third was to establish what support mechanisms were available to these households to cope with the challenges and problems they face in generating an income and catering to their household needs. Methodologically the study employed a qualitative research approach with in-depth semi-structured interviews being used to collect data from five female-headed households. The data was then analysed using an interpretive approach and presented textually. Essentially the study found that in terms of the first research objective that coloured female-headed households engaged in a range of livelihood activities in order to earn a living, with informal trading being the main livelihood activity that the participants relied on to acquire an income to support their households. With regards to the second objective, it was revealed that the female heads interviewed faced numerous challenges ranging from economic to social problems that limited their ability to develop sustainable livelihoods, thereby increasing their risk to fall into poverty and validating their feminization of poverty. In terms of the third and last objective, the study found that the female heads did not have many reliable support mechanisms available to them thereby limiting their ability to achieve financial and social empowerment.

  • Description: This study was conducted at Engcobo Local Municipality in the Eastern Cape Province to assess the role of municipal structures and systems in the implementation of small town revitalisation strategy. From onset, it highlights that numerous attempts to implement small town revitalisation have failed because of lack of institutional capacity. In addressing this problem, the study outlined the following objectives. To assess role played by municipal structures and systems on implementation of small town revitalisation. To identify institutional challenges experienced during implementation of small town revitalisation strategy. To propose alternative institutional measures that can lead to effective implementation of small town revitalisation. In achieving the study’s objectives; literature from both developed and developing countries was reviewed and it was learnt that institutional capacity is important for efficient implementation of the strategy. Systems theory was also reviewed so as to provide conceptual basis that underpins this study. Data was collected through primary methods and secondary sources. Research participants were chosen by random sampling from councillors, managers, business and traditional leaders. Research findings revealed that there were institutional problems which hinder implementation of the strategy such as lack of competent human resources, insufficient budget and shortages of machinery. Through analysis of findings, the research proposed that small town revitalisation strategy should be reformulated and role of municipal structures be clearly defined. Both councillors and officials should be capacitated. The study further recommended that local people and stakeholders should be involved in the conception and implementation of small town revitalisation strategy. Areas for further research were proposed at the end.

  • Description: The continued growth of world commerce has led to the advance of the permanent establishment principles. These principles are, however, constantly challenged by the developments of e-commerce. This thesis considers the taxing of a permanent establishment and the influence of e-commerce on the concept of a permanent establishment. In 2000, the Organisation for Economic Co-operation and Development (“OECD”) developed and introduced guidelines on how to deal with e-commerce in the context of a permanent establishment. Since the OECD guidelines on e-commerce were issued, the permanent establishment principles have come under further scrutiny. The latest development came about in 2013 with the release of the Base Erosion and Profit Shifting (“BEPS”) Action Plan. This Action Plan addresses the intention of the OECD to deal with the taxing of the digital economy. With the development of e-commerce and the result of e-commerce creating intangible boundaries between countries, the concept of a virtual permanent establishment has emerged. This has resulted in the need to tax a presence of an enterprise in a jurisdiction where no actual physical connection can be established. Various authors have made suggestions on how to ensure that an economy in which business is being carried on is correctly compensated for in the form of taxes. The source of income is the driving force for the imposition of taxation today. The main goal of this thesis was to explore the alignment of the concepts of a permanent establishment and e-commerce in the digital economy. This study therefore examined the concepts of both permanent establishments and e-commerce, and explored authors’ views and suggestions on how to deal with the inter-related effects of these two concepts. The relevant Action Points in the OECD Action Plan were also considered. , Maiden name: Venter, Michelle

  • Description: The purpose of the study is to assess risk factors associated with developing asthma and tuberculosis. Methodology: A quantitative study was conducted on 133 randomly selected tuberculosis respondents, 91 of whom were suffering from TB at the time of the study. 120 respondents were also selected randomly for asthma of which 82 were asthmatic. Data were collected by using a self-structured questionnaire. The statistical analysis was done with the statistical package for social sciences (SPSS, version 18) using the descriptive statistics and logistic regression model. Results: Findings from the study show that a large percentage of the participants for both diseases were male, and the carriers of the diseases were also mostly male. Amongst the factors assessed, smoking, a weak immune system and a history of contact with tuberculosis infected persons were factors independently associated with developing tuberculosis. In the case of asthma, family history, smoking and exposure to allergen irritants were the factors independently associated with developing the disease. Conclusion: The findings highlight the need for increasing awareness through information, education and communication to address the risk factors of tuberculosis and asthma in order to decrease the rate of outspread. Recommendations: Factors triggering asthma among humans should be avoided. Since tuberculosis can be contracted through person to person contact, proper sanitation and regular medical attention are advocated for safeguarding personal and public health.

  • Description: Introduction. A well-recognized problem exists when commonly employed tests developed in the United States (US) or United Kingdom (UK) are accepted unconditionally for use on local relatively disadvantaged populations, as these tests have questionable validity and therefore incur a high risk of misdiagnosis. Cross-cultural normative research has been conducted in South Africa on some of the Wechsler intelligence scales with respect to participants stratified for level and quality of education, age, race and language, including a study on the Wechsler Intelligence Scale for Children – Fourth Edition (WISC-IV) for learners with Grade 7 education (age 12 to 23). The aim of the current study was to conduct a partial duplication of the earlier WISC-IV South African norming study that specifically targeted a younger group of educationally disadvantaged children at a lower level of education. Method. Participants were Black Xhosa-speaking Grade 3 learners in the age range 8 to 9 (N =32 ), who were being schooled in the disadvantaged educational setting of the former Department of Education and Training (former-DET) schools. The WISC-IV results of the current study were statistically compared with the WISC-IV results from Shuttleworth-Edwards, Van der Merwe et al. (2013) study. Results. There was a significant lowering of between 20 to 30 IQ points relative to the UK standardisation on WISC-IV scores for this sample of Grade 3 Xhosa-speaking learners, replicating the earlier outcome for Grade 7 Xhosa-speaking learners relative to the UK standardisation. No differences were in evidence within the WISC-IV sample for the female and male participants on any of the indices. There was equivalence between the Grade 3 and Grade 7 Xhosa-speaking learners on all subtest and Index scores with the exception of the Digit Span subtest. Conclusions. The results confirm prior research indications of the negative impact of educational disadvantage on IQ test results and the need for this to be taken into account by the availability of socio- culturally relevant norms.

  • Description: Historically, the Consumption Capital Asset Pricing Method (C-CAPM) has performed poorly in that estimated parameters are implausible, model restrictions are often rejected and inferences appear to be very sensitive to the choice of economic agents' preferences. In this study, we estimate and test the C-CAPM with Constant Relative Risk Aversion (CRRA) using time series data from Germany, South Africa, Britain and America during relatively short time periods with the latest available data sets. Hansen's GMM approach is applied to estimate the parameters arising from this model. In general, estimated parameters fall outside the bounds specified by Lund & Engsted (1996) and Cuthbertson & Nitzsche (2004), even though the models are not rejected by the J-test and are associated with relatively small minimum distances.

  • Description: From Integrative summary: This document consists of three sections namely, an evaluation report (section 1), literature review (section 2), and research methodology (section 3). The evaluation report sets out the terms of reference for the research as well as identifying the objectives of the research. It also contains a summary of the literature review section, as well as a research methodology section summary. The literature review section contains a detailed review of the literature used in this study. This section sets out by reviewing existing literature on the topic of leadership, discussing the key elements of organisational culture and includes a short discussion on the typologies of culture. The Competing Values Framework as an organisational culture typology is discussed in greater detail, since it forms the foundation upon which the measurement and data collection tools for this research are founded. The research methodology section explains the research methodology and design employed in this study. This section also addresses some of the ethical considerations for this research, as well as how the researcher addressed them. There is also a brief discussion on the limitations of the research and the application of the results. This research focused on a business unit within Absa Business Bank, named Enterprise Business Gauteng Region, with the aim of investigating the “current organisational culture” in the business unit and the leadership competencies profile of its 11 Sales Managers. This was to provide the basis and departure point for the strategic organisational culture change that the new business unit head would have wanted to effect as the business has a history of non-performance, which the new business unit head aims to change. In order to diagnose the “current organisational culture” type, an organisational culture measurement tool based on the Competing Values Framework was used. The Competing Values Framework is a four-category organisational culture typology developed by Cameron and Quinn. The framework is based on two dimensions, how stable or flexible the organisation is, and how externally or internally focused it is. This framework was also employed to establish the leadership competencies profile of Sales Managers, as observed and experienced by the frontline staff, as well as the “desired organisational culture”, as intended by the new business unit head. Through hypotheses testing, the research revealed a statistically significant difference in perceptions of culture between males and females in the business unit. The perceptions of the female frontline staff about the “current” business unit culture indicated that they find it not to be empowering and less allowing for individuality and risk taking when compared to the male staff. The research also concluded that there is no statistically significant difference between leadership competencies associated with the four categories of the Competing Values Framework in the business unit. Comparisons between the “current” and the “desired” organisational culture revealed a misalignment. The main recommendations to the new business unit head were to get the leadership competencies of the Sales Managers aligned with the “desired organisational culture” state, and drive a purposive organisational culture change effort. To support this culture change, the espoused values of the business unit would need to be aligned to the desired culture state. To address the differences in perceptions of culture between males and females the business unit head would need to be mindful of the greater need to empower women either in their current roles, or by way of promotions to senior roles.

  • Description: A descriptive research with quantitative approach examined human capital in Non-profit organisations with three objectives: to ascertain the qualifications and skills essential in the non-profit sector; to determine if Non-profit organisations provide training and education support for its workforce and to describe formal education level of NPO workforce in South Africa. The study population were employees of Non-Profit organisation (NPO’s) operating in Cape Town. In order to evaluate human capital, workforce level of education of the non-profit organisations in South Africa, significant to addressing most Non-profit organisations challenges in recent time, a survey has been conducted among the South Africa non-profits, identified on the basis of the simple random sampling. 300 questionnaires were sent out, and 147 valid responses received. Empirical results from the selected civil society organisation seem to suggest and concluded that Non-profit organisations workforce are educated up to Honours degree level on average. However, that education may not be priority for the workforce, rather passion for the job and that satisfactory human capital management reduces turnover, in order word attract and enable retention of productive workforce for non-profit organisation effectiveness.

  • Description: The aim of this study was to establish whether samples of South African-mined clinoptilolite could be used to remove selected metal cations from aqueous solution. The clinoptilolite samples supplied, (by Pratley SA) were in four different particle sizes. Batch study results revealed a decrease in the initial metal concentration in samples that were in contact with clinoptilolite. The finer particle size clinoptilolite had a greater capacity to remove metal cations from aqueous solution. However, ion-exchange results from atomic absorption analysis showed that the larger particle sizes, removed more magnesium ions. Magnesium was the only ion investigated in this study that was present as an exchangeable ion in the Pratley clinoptilolite chemical formula, (MgCaNa2K2)2.5(AlO2)7(SiO2)30.21H2O. Results from the ion-exchange studies showed that the decreasing order of percentage metal removal at pH 3.00 was as follows: Pb > Ni > Cu > Fe > Mg. The mass of metal ions that accumulated on one gram of clinoptilolite as determined from the isotherms was calculated to be 6.16 mg/g for lead and 0.74 mg/g for copper. Data from the lead equilibrium studies were fitted into Langmuir and Freundlich equations and linear regression was used to calculate linearity coefficients for the isotherms. The results showed that the removal of lead ions by clinoptilolite is complex as both monolayer and multilayer adsorption occurs on a heterogeneous surface.

  • Description: In this study we conduct wind resource assessment to evaluate the annual energy production of a wind turbine. To estimate energy production of a wind turbine over a period of time, the power characteristics of the wind turbine are integrated with the probabilities of the wind speed expected at a chosen site. The first data set was obtained from a wind farm in Denmark. We propose several probability density functions to model the distribution of the wind speed. We use techniques from nonlinear regression analysis to model the power curve of a wind turbine. The best fit distribution model is assessed by performing numeric goodness–of–fit measures and graphical analyses. Johnson’s bounded (SB) distribution provides the best fit model with the smallest Kolmogorov–Smirnov (K-S) test statistic . 15. The four parameter logistic nonlinear regression (4PL) model is determined to provide the best fit to the power curve data, according to the Akaike Information Criterion (AIC) and the Bayesian Information Criterion (BIC). The estimated annual energy yield is compared to the actual production of the wind turbine. Our models underestimate the actual energy production by a 1 difference. In Chapter Six we conduct data processing, analyses and comparison of wind speed distributions using a data set obtained from a measuring wind mast mounted in Humansdorp, Eastern Cape. The expected annual energy production is estimated by using the certified power curve as provided by the manufacturer of the wind turbine under study. The commonly used Weibull distribution is determined to provide the best fit distribution model to our selected models. The annual energy yield is estimated at 7.33 GWh, with a capacity factor of 41.8 percent.

  • Description: The South African local government is expected to conform to all national policy directives including the principle of gender equality. Local government provides an immense opportunity for redressing imbalances and empowerment of women as they are the most negatively affected by poverty as a result of inequality. The South African Government has developed a wide range of legislation that ensures that women are empowered and participate in their own development. With all the legislation in place, women‟s empowerment as envisaged in the South African Constitution has, however, not yet been yielded the desired results as evidenced by the fact that women continue to remain disadvantaged in relation to men. This study therefore seeks to investigate whether and how the Nelson Mandela Bay Metropolitan Municipality (NMBMM) has mainstreamed gender in support to the principles of gender equality and women‟s empowerment in the implementation of Integrated Development Planning (IDP) with particular reference to wards 15 and 17. The researcher used a mixed methods research approach, this means that the study followed both the qualitative and quantitative approaches for in-depth understanding followed in the design and implementation of the IDP process. Data was collected from women participants by conducting surveys, making use of questionnaires. Structured interviews were conducted with municipality officials in order to give more insight more insight into how the IDP process is initiated in the Nelson Mandela Bay Metro Municipality. The findings of the study revealed that there is a lack of a strategic understanding of gender mainstreaming particularly by the leadership of the municipality. This as a result, has made operationalisation and engendering the IDP difficult. Due to this strategic vacuum, gender is generally not taken seriously when compared to other developmental challenges such as infrastructure provision. Moreover, the municipality does not have a coordination mechanism nor does it have a proper consultation mechanism to ensure that the nature of development projects is appropriate, effective and actually targets women‟s developmental needs. The leadership of the municipality must commit to the process of gender mainstreaming if the IDP is to be an effective tool in addressing the gender imbalances.
