  • Description: China’s economic involvement in Africa has increased rapidly over the past decade. China’s involvement in Africa has become one of the controversial topics in the development literature. The background of the study is that Sino-African relations can be grouped into two phases thus: past relations and contemporary relations. The study notes that past relations are different from contemporary relations because while the former are mainly characterised by solidarity, the latter are mainly categorized by economic relations. The study is a historical narrative of China’s economic involvement and the impact in Africa over the past decade. The study draws its arguments from the myths which label Chinese resurgence into Africa as neo-colonialism and that China’s reinvigorated interest in Africa is entirely based upon its own economic pursuits since it has developed into an economic powerhouse over the past decade. Additionally, it has been reported that China disregard good governance in Africa by engaging African governments which are corrupt and which possess poor track human rights. In order to determine if China is pushed into Africa by its economic pursuits and whether China disregards good governance, the study uses two case studies thus: Zimbabwe and Zambia. Zimbabwe one the one hand represents a pariah state, which is viewed as corrupt and a nation which has a poor record of human rights while Zambia, on the other hand represents illiberal regimes and democratic regimes with commodity based economies. The research discovered that China’s economic involvement in Africa presents both opportunities and challenges for African countries. In some instances, China has aided GDP growth in some African countries while in some instances, it has increased unemployment. In conclusion, the study also discovered that China does not involve itself in African domestic affairs hence it has been criticised for encouraging corruption and abusing of human rights.However, the study notes that these issues are mainly domestic hence Africans are entirely to be blamed for such practices, not China.

  • Description: The purpose of this qualitative case study involving six secondary school teachers was to obtain insight into how geometry is taught in selected Nigerian and South African high schools. It also aimed, by making use of the van Hiele model of geometry instruction, to elucidate what possible learning opportunities observed instructional methods could offer learners in the subject. The sample comprised three mathematics teachers from Nigeria and three mathematics teachers from South Africa, all of whom were selected using purposive sampling techniques. Instructional activities in six geometry classrooms were recorded on videotape. The van Hiele learning phases provided the framework for data analysis. The findings of this study indicate that observed teaching methods in geometry classrooms in the participating schools offer learners scant opportunity to learn geometry.

  • Description: In 1996, Zimbabwean graphic designer Chaz Maviyane-Davies created a set of human rights posters which represent several articles of the Universal Declaration of Human Rights, from what he calls an “African perspective”. In this study I investigate how Maviyane-Davies has constructed ‘African-ness’ and probe what he refers to as the “alternative aesthetic” that he is trying to create. I use a visual social semiotic approach to examine the discourses he draws on to re-image and re-imagine Africa and Africans in a manner that contests the stereotypical representations found in political, news and economic discourses about Africa, paying particular attention to the ways he uses images of the body. My analysis of the posters shows how complex and difficult it can be to contest regimes of representation that work to fix racialised and derogatory meanings. In response to the pejorative stereotypes of the black body, Maviyane-Davies uses images of strong, healthy, and magnificent people (mostly men) to construct a more affirmative representation of Africa and Africans. Significantly, he draws on sports, touristic, traditional and hegemonic discourses of masculinity in an attempt to expand the complexity and range of possible representations of African-ness. In so doing he runs the risk of reproducing many of the stereotypes that sustain not only the racialised and gendered (masculinist) representations of Africa, but also a sentimentalisation and romanticisation of a place, a people and their traditions. Apart from women in prominent positions, other conspicuous absences from these images include white people and hegemonic references to Western modernity. I do not believe he is discarding whites and modernity as un-African, but is rejecting the naturalisation of whiteness as standing in for humanity, and particular icons of Western modernity as significations of ‘modernity’ itself

  • Description: The South African criminal justice process is such that there is an inevitable lapse of time between the arrest of the offender and his or her subsequent trial. The pre-trial incarceration presents a special problem. Between the arrest of the accused and release, the accused is being deprived of his or her liberty in circumstances where no court of law has pronounced him or her guilty. The right to bail is well entrenched in South African criminal justice system both in the Constitution Act and Criminal Procedure Act. Bail is always in the form of contract between the State and the accused, even though at times it may be opposed by the State. In the past the legal position based on the case law was that the presumption of innocence in bail proceedings operated in favour of the applicant even where it was said that there was a strong prima facie case against him or her. This position has slightly changed in that the courts in bail applications are not concerned with guilt, but that of possible guilt only to the extent that it may bear on where the interests of justice lie in regard to bail. The onus of proof in bail applications, other than Schedule 5 and 6 offences is borne by the State. Where Schedule 5 or 6 is applicable the onus is on the applicant. There are different requirements between schedule 5 and 6 that must be met by the applicant before release on bail is granted. In Schedule 5 offences the bail applicant must satisfy the court that the interests of justice permit his or her release. In determining whether the interests of justice permit the release of a particular applicant on bail, the courts are guided by the provisions of section 60(4) to (9) inclusive of section (11B)(c) of the Criminal Procedure Act. In such determination the courts must also take into account of section 60(60)(a) to (g) of the Criminal Procedure Act. In Schedule 6 offences there are two requirements namely: the exceptional circumstances and the interests of justice. The term “exceptional circumstances” does not have a closed definition. Both requirements must be established by means of written or oral evidence to the satisfaction of the court before bail may be granted. As pointed out above, the State may still oppose the release on bail of the applicant. It is now accepted in bail applications that ordinary circumstances may in particular context be blended with exceptional or unusual elements. In such cases the court is expected to apply its independent evaluation of evidence in order to determine whether the exceptional circumstances in the interests of justice permit the release on bail. Similarly to the South African bail jurisprudence the Rome Statute of the International Criminal Court recognises a right of the arrested person to apply for the interim release. It also recognises the need to establish exceptional circumstances for such release. The South African bail jurisprudence recognises the right to bail, and places reasonable and procedural limitations founded on the constitutional values and interests of justice. There are still practical challenges that need to be addressed as a results of the stringent requirements in section 60(11)(a) and (b) of the Criminal Procedure Act that relate to Schedule 5 and 6. It is therefore recommended that there is a need for the following: 1. Legislative intervention that will regulate and limit the time spent on investigations where bail has been refused. 2. Legislative intervention that will provide for an automatic review procedures in Schedule 5 or 6 offences where bail is refused on grounds that the interests of justice do not permit the release of the applicant on bail or for failure to prove exceptional circumstances. It is submitted that this may assist in reducing refusals of bail based on mistaken understanding of the law or facts or irregularities that may be prejudicial to the applicant or the administration of justice; or 3. Legislative intervention that will make it mandatory for a court that refuses to grant bail to reconsider its decision after a certain period in future provided that the trial has not been commenced with, in order to determine whether further incarceration is necessary or proportionate to the offence. It is submitted that this may assist the court to enquire into unreasonable delays on investigations or changed circumstances of the applicant in order to enable the court to reconsider its previous decision if necessary. This may further assist in offences where it is foreseeable that the trial court is likely to pass a partly or wholly suspended sentence in case of conviction. For example some cases fall within the scope of Schedule 5 by virtue of a previous conviction on Schedule 1 or release on bail on a Schedule 1 offence. The above recommendations may directly or indirectly contribute in balancing the scales of justice during the bail proceedings and its aftermath. These may contribute to the reduction of high numbers of the in custody awaiting trial prisoners while not compromising the current bail procedures.

  • Description: This study is an outcome and impact evaluation of Concern Worldwide (CW) community feeding program. Concern Worldwide conducted a community feeding program in Nyanga District in 2012. It was responding to the National Food Report (2011) issued by the government on the food shortages in Nyanga District. The feeding program supported Nyanga communities with nutritional supplements and food provisions to households. The goal of Concern Worldwide was to address the problems of hunger, household food insecurity, malnutrition and poverty which were affecting people in Nyanga. Four evaluation questions about program outcomes were used as a framework for the evaluation and included: How feasible are livelihood feeding schemes as methods of providing food safety net?; How are short-term emergency programmes converted into long term benefits for communities?; What are the interventions available in the program to ensure fulfilment of goals and community empowerment?; What lessons can be derived from the projects that can be used in future by Concern Worldwide and other NGOs involved in emergency and other developmental projects? For the purposes of the study three data sources were consulted. These included program documents, CW officials and beneficiaries. Data collection methods used included face to face interviews and both closed and open ended questionnaires. The qualitative data was analysed through content analysis and presented graphically and descriptively. The findings showed that the community feeding program made some impact through food provisions and agriculture inputs to the beneficiaries which was highly regarded and appreciated. It also managed to provide training on drought resistant crop farming and management of harvests. Monitoring and evaluation of the feeding program was identified as a critical tool in creating efficiency and accountability of the program. Although training was provided to all the beneficiaries, not all were directly involved in the daily routine activities of the program a goal that is not achievable in the context of community feeding program.

  • Description: The purpose of local economic development (LED) is to build up the economic capacity of a community, to improve its economic future and the quality of life for all. It is a process by which public, business and nongovernmental sector partners work collectively to create better conditions for economic growth and employment generation (World Bank, 2006). In achieving the above definition of LED by the World Bank, the participation of community members in this process cannot be over emphasized. Women entrepreneurs are a driving force in today’s modern world. Most researches on women entrepreneurs in developed countries have showed that there are significant improvements in the economic growth of these countries as a result of the entrepreneurial activities of these women. However, there are limited statistics on the impact of women entrepreneurs in developing countries. The context of this research area is the Nelson Mandela Bay Municipality (NMBM). This research makes a contribution to the existing body of knowledge about the promotion of LED through the participation of women entrepreneurs in NMBM. A group of women entrepreneurs in the metro completed a questionnaire. The aim of the questionnaires was to help identify their nature of business, years of being in business and most importantly, challenges each one of them encounter in carrying out their business operations and in developing their entrepreneurial skills. The research methods used in the study are the qualitative and quantitative methods. The qualitative method approach is used in the literature review. The literature review formed the conceptual basis against which the information gained from questionnaires were analysed. The quantitative method included the use of questionnaires. The data collected in this study revealed that the activities of women entrepreneurs contributed in their own little way to the growth and development of the metro. The study further reveals that finance is one of the major challenges of the women entrepreneurs as supported by the findings in the literature review. Therefore, if access to finance and support system are made readily available for women entrepreneurs, they would be able to make a significant impact in the development of the metro and nation at large. In conclusion, the researcher has been able to identify some of the challenges women entrepreneur face through the experience of the respondents in the study. The researcher has also been able to demonstrate how the aims and the objectives of the study have been met.

  • Description: Adolescent pregnancy among students across South Africa is a growing concern. The high incidence of dropping out of school results in greatly diminished chances of success and independence for many. Sex education forms part of the life orientation curriculum, and it has been put in place by the Department of Education as a measure to reduce the prevalence of adolescent pregnancy. Parents of adolescents play a vital role in educating their children on sexual matters, secondary to that is community educations on sexual matters in aid of uplifting communities. The aim of the study was to explore the perception of how effective sex education could be a means of reducing pregnancies in the Blue Crane Route Municipality. To achieve this aim, three objectives and three research questions were articulated. The objectives were to explore the course content of life orientation provided to adolescents, to investigate by questioning adolescents concerning the importance of life orientation in their lives and to examine the factors responsible for the escalation of adolescent pregnancies in the municipality. The research questions were: How adequate was the course content of life orientation in helping adolescents in their sexual lives? How useful was life orientation to adolescent girls? What are the factors that increase the incidence of adolescent pregnancies in the municipality? Qualitative data was obtained through semi-structured interviews; focus group discussions were conducted with students, social workers and life orientation educators and observations made by them were recorded. Data was analysed thematically and was supported by relevant literature. The findings revealed that sex education is not effective in reducing pregnancies in the Blue Crane Route Municipality. The figures for adolescent pregnancy in schools have increased since 2007, when sex education was introduced as part of the life orientation curriculum. Accordingly, it is recommended that the Department of Education should re-evaluate the curriculum and appoint educators who are sufficiently trained in life orientation to make learners properly aware of the consequences of unwanted pregnancies.

  • Description: The article reflects on why I opted for Political Science as my career. It tells of a society where once black women could only imagine themselves either as maids, teachers or nurses—this was my mother's world. The narrative shows how a racialised and gendered history shapes both my hopes for a particular kind of international relations theory and practice, as it shapes my frustrations and anxieties about my own future in the discipline. I also locate my place in the discipline within broader global ‘disruptions’ that see previously marginalised actors moving to the centre of international life. I also attempt to demonstrate that international relations today is located in globalised peace but within localised extremes of poverty and privilege. I make the case that the challenge to International Relations (IR) theory today is to find a language, a new language, in which to articulate the contradictions of a globalised peace that exists within localised extremes of poverty and privilege.

  • Description: Polymer composite fibers doped with phthalocyanines and phthalocyanine-functionalized gold nanoparticles were developed. The phthalocyanine and phthalocyanine-functionalized gold nanoparticles have been characterized using UV/Vis, fluorescence and X-ray photoelectron spectroscopy (XPS), time correlated single photon counting (TCSPC), time-resolved emission spectra (TRES) and transmission electron microscopy (TEM). The changes in photophysical and photochemical behavior of the phthalocyanines induced by their interaction with gold nanoparticles and polystyrene were also investigated. In the presence of gold nanoparticles, the fluorescence lifetimes and quantum yields of the phthalocyanine decreased, whereas the singlet oxygen quantum yield increased. This work shows that polymer composite fibers could be used as functional fibers for a variety of applications such as gas sensing when using the advantageous properties of phthalocyanines and gold nanoparticles.

  • Description: Whether investor sentiment has any authority over financial markets has long been a topic of discussion in the field of finance. This study investigates the relationship between investor sentiment and share returns in South Africa. Determining this relationship will add to the existing work which has documented important determinants of share returns on the stock exchange in South Africa, as well adding to the inconclusive link between sentiment and the South African financial markets. Does sentiment influence share returns or do share returns influence sentiment? Using quarterly data for the period 1996-2010, the study makes use of the FNB/BER Consumer Confidence Index as a proxy for investor sentiment, and the FTSE/JSE All Share Index to represent the South African financial markets. A regression analysis was conducted along with granger-causality tests, impulse response functions and variance decompositions in order to determine the nature of this relationship. The results showed that investor sentiment has a statistically significant relationship with share returns in South Africa. However, sentiment is only able to account for a very small portion of the variation in returns, with returns able to account for a larger portion of the variation in sentiment. Therefore investor sentiment is not a suitable predictor of share returns in South Africa. In addition, granger-causality tests indicate that returns are actually the leading indicator, suggesting that changes in South African investors’ confidence levels occur following changes in the state of the JSE. The limitations of the study include the infrequent nature of the sentiment measure used, thereby failing to capture important changes in sentiment and their immediate impact on financial markets. In addition, the sentiment of foreign investors must be taken into account due to the large foreign investment in the JSE.

  • Description: Background and Aim: Microalgae are a potential economical source of omega-3 fatty acids, which are known for their health benefits. Omega-3 fatty acids derived from microalgae are however still expensive due to high costs involved in production. These costs can partly be attributed to cultivation of microalgae in unialgal cultures, which are prone to contamination, difficult to scale up and require stringent control of growth conditions. This study therefore is aimed to investigate the feasibility of using a mixed microalgae culture for the production of omega-3 fatty acids. Methods and materials: The microalgae were grown under uncontrolled conditions in a hanging-bag photo-bioreactor, with only the phosphorus-nitrogen ratio (P:N-ratio) varied. Variations in the different population proportions in the culture were studied and related to the biomass, total fatty acid and omega-3 fatty acid productivity of the culture. Finally, a comparison was made between the results obtained in this study and similar studies found in literature. Results and discussion: The mixed culture used was composed of several green microalgae, whose proportions varied with P:N-ratio, season, and age of the culture. Different interactions between the populations were observable, and these were thought to influence the culture’s biomass, total fatty acids (TFAs) and omega-3 fatty acid productivity. The TFA content of the culture was ~10-20% by the end of the exponential phase, depending on the nutrients supplied. The fatty acids were composed of mostly unsaturated fatty acids, the majority of which were omega-3 fatty acids; C18:3ω3 (up to 50% of TFA), C16:4ω3 (up to 15%) and C18:4ω3 (up to 5%). Other fatty acids observed included C16:0 (up to 25%), C18:1ω9/C18:1ω8 (up to 20%), C18:2ω6 (up to 5%), traces of C18:0, C18:3ω6, C17:0, C16:3ω3 and C16:1ω7 were also detected. The presence of these fatty acids was found to vary depending on season, P:N-ratio, and age of the culture. When compared to studies in the literature, the mixed culture was found to perform better than, or as well as reported studies, where unialgal cultures were cultivated under controlled laboratory conditions. Conclusion: In view of the reported advantages of cultivating mixed cultures, the production of omega-3 fatty acids via such cultures appears attractive. More research however is needed to optimise the culture; study interactions between the organisms and their effect on biomass, total fatty acid and omega-3 fatty acid productivity. Finally, the economic implications of using mixed cultures need to be evaluated as well.

  • Description: The use of indigenous knowledge (IK) and indigenous bio-resources by pharmaceutical and herbal industries has led to concerns about the need to protect IK in order to prevent biopiracy and the misappropriation of indigenous knowledge and resources. While some commentators believe that intellectual property rights (IPR) law can effectively protect IK, others are more sceptical. In order to contribute to the growing debate on this issue, this study uses the relatively new and as yet largely critically unanalysed Masakhane Pelargonium case to address the question of whether or not IPR law can be used to effectively protect IK. It is argued here that discussion about the protection of IK is a matter that must be located within broader discussions about North-South relations and the continued struggle for economic and political freedom by indigenous people and their states. The Masakhane case suggests that IPR law in its current form cannot provide sufficient protection of IK on its own. Incompatibilities between IPR law and IK necessitate that certain factors, most important of which are land, organised representation, and what are referred as 'confidence and network resources', be present in order for IPR law to be used with any degree of success. The study also reveals various factors that undermine the possibility of using IPR law to protect IK. In particular, the study highlights the way in which local political tensions can undermine the ability of communities to effectively use IPR law to protect their knowledge. The thesis concludes with several recommendations that will enable indigenous communities and their states to benefit more substantially from the commercialisation of their bio-resources and associated IK.

  • Description: Integrated Quality Management System (IQMS) consists of three policies, namely; the Developmental Appraisal System; Whole School Evaluation and Performance Management System, designed to foster a culture of continuous improvement in schools. However research has cast doubt on the integration of the three policies. It has been argued that the implementation of the three policies is fragmented, with diverse goals, multiple purposes, values that are at variance, and conflicting expectations, causing tension between personal needs and improvement needs. The aim of this study is to understand how IQMS practices and systems promote continuous improvement. This was a case study of four primary schools located in different contexts in East London District. In-depth interviews were conducted on a total of 12 participants across all the schools. There were three main findings. First, IQMS is understood and practised as an external intervention. It appears not to have been internalised as a quality management system. Second, the participants were ambivalent about the IQMS practices as enablers and as barriers of continuous improvement. A fair amount of educators did not view IQMS as daunting as some had portrayed it. Third, There were blurred lines between what participants recognised as systems and the actual practices in the implementation of the three IQMS policies . There was no evidence of systemic thinking on the part of practitioners. As far as the IQMS systems and practices are concerned, no direct mention of evaluation variables or paradigms can be found, making it somehow complex for educators to distinguish between identifiable systems and practices. Finally, the external and internal quality assurance practices seemed to have been subsumed under managerial imperatives of compliance and accountability. Educators revealed that they merely undertake the process as they are compelled to do so as an expectation or requirement by the Department of Education. Given the above findings it can be concluded that and if continuous improvement is to be achieved through the IQMS strategy, there is a need to re-invent it such that , embedded in its systems and structures is a culture of continuous improvement. The reconfiguration of IQMS should look for mechanisms for integrating the three policies. The study recommends, for practice there should be a balance between professional development of educators and managerial imperatives that demand compliance and accountability. Further study must be undertaken to unravel the three IQMS policies.

  • Description: This psychobiography is focused on the life of Glenda Watson-Kahlenberg, whose life history epitomises the redemptive theme of triumph over tragedy. A phenomenological approach to the study allowed the researcher to observe the participant‟s lived experience through the theoretical lens of Frankl‟s conceptualization of a meaningful and full existence. A holistic perspective of factors contributing to redemption was accommodated by the Biopsychosocial-spiritual Model. The aim of this longitudinal revelatory study was to illuminate the process of redemption in a life, which leads to restoration and wholeness. This study breaks with traditional psychobiography – in that a life in progress has been selected; and personality development is not the key focus. This psychobiographical undertaking was anchored in qualitative research in the form of a single case study. Four types of triangulation were utilized, namely: data, investigators, theory and methodological triangulation. In addition, Alexander‟s identifiers of saliency, Miles and Huberman‟s data-management guidelines, Schultz‟s prototypical scenes, and Guba‟s criteria for trustworthiness, guided the methodology to ensure reliable data extraction and interpretation. The present researcher was in search of a deeper understanding of the enabling factors facilitating a restorative process in a life that was challenged by setbacks. Given the increasing pressures facing individuals in this modern era, the redemptive theme holds particular relevance, and was graphically demonstrated in the life of the participant who experienced trauma, widowhood, divorce, single parenthood, and a spate of medical and psychological setbacks. The findings suggest that the mental health clinician‟s utilisation of Frankl‟s conceptualisation of meaning in the most challenging circumstances, proffers itself as an all-purpose life-tool which enables individuals to overcome their challenges. The study demonstrated that gaining meaning in life is inextricably tied to an implicit legacy-oriented worldview. Of significance, is the role of forgiveness which emerged as the central redemptive catalyst. In this study, the resolution of past hurts through forgiveness, and the search for meaning, merge, forming an arterial theme in the life story of the participant. The dual impact of these factors not only reversed contaminated life-scripts, it also birthed a new calling in life which set the participant on a generative life course. The findings related to a redemptive life not only confirms existing theory, but also adds perspectives not previously considered. In addition, the findings related to the role of forgiveness has positive implications for the individual‟s physical and psychological wellbeing. Greater intentionality on the part of therapists to thread forgiveness into their practice, remains invitational in the light of the eugraphic impact demonstrated in this study.

  • Description: Public service delivery is a major challenge to governments in both the developing and developed worlds. Governments have used various strategies to enhance service delivery. These strategies have resulted in varying outcomes and levels of service delivery. In the Kenyan government, the strategies to enhance service delivery include: Results Based Management strategies, service charters, Information Communication Technology (ICT), performance contracting, and strategic plans. This study is an investigation of reforms in the Ministry of Immigration and Registration of Persons (MIRP), Kenya. The study sought to investigate the effects of Results Based Management on service delivery; to investigate the effect of strategic planning on service delivery in Kenya; to investigate the effect of ICT on service delivery in Kenya; and to investigate the effect of Business Process Re-engineering (BPR) in service delivery. This study utilized a descriptive research design where the researcher investigated and collected factual data to describe the situation or problem. Secondary data was sourced from document reviews. Data was analyzed as it was collected. The researcher classified the data in terms of the topic, themes and content. The broad topic and themes of the data collected was based on the research objectives of this study and included: use of Information Communication Technology, Business Process Re-engineering, Results Based Management, and strategic planning. The findings revealed that the department has utilized Results Based Management, strategic planning, Information Communication Technology, as well as Business Process Re-engineering tools in reforming public service delivery towards effectiveness and efficiency. Furthermore, this study also revealed that the department has accrued various benefits as a consequence of these tools despite the challenges facing their implementation. According to the report, the reform programs have enhanced greater transparency in service delivery, improved accountability, responsibility in employees, enhanced policy coherence and strengthened capacity. these advantages are evident to the Department of Immigration. the study recommends that the use of Results Based Management, ICT and Business Process Re-engineering policies and changes should be implemented to improve service delivery in the Ministry of Immigration and Registration of Persons. In addition, the study recommends the following further studies: the study should be replicated to other public organizations (agencies) to allow for comparison of the findings of this study; the study recommends research on the success of public organizations in achieving objectives of their strategic planning (this is based on the challenges identified facing strategic planning in the Department of Immigration); and, finally, this study recommends future research on the relationship between Business Process Re-engineering (BPR) and efficient service delivery. This study will provide insight to what extent BPR affects service delivery.

  • Description: This is a quantitative study which explores whether there is a positive relationship between customer satisfaction as perceived by corporate customers and revenue generated from such customers of the corporate division of a single South African bank. This research report has three sections, namely the (1) academic paper which comprises a condensed literature review, research methods, results and discussion, (2) an expanded literature review, and (3) an expanded research methodology. Although these three sections are interrelated, they may be considered stand-alone documents. A review of literature contends that customer satisfaction has been a topic of interest for over four decades when, in 1965, the concept was first introduced to literature by Cardozo. Even in these early stages it was hypothesized that higher customer satisfaction would lead to repeat purchasing and cross selling. Thus, for some time, researchers have proposed that a link exists between customer satisfaction and a company’s bottom line, ultimately alluding to the notion of positive associations between customer satisfaction, revenue and profitability. The corporate banking division of a South African bank has dedicated significant time and economic resources to monitoring and improving the satisfaction of their corporate customers each year. With a focus on this single corporate banking division, this quantitative study used secondary customer satisfaction data to establish whether a positive relationship between customer satisfaction with a bank representative or more formally termed, the ‘transactional banker’ (TB) and revenue at an account level exists. The study used a one-dimensional customer satisfaction construct summated from several variables or a one-dimensional multi item scale. This quantitative study made use of secondary data obtained through customer satisfaction surveys conducted with the division’s clients in three waves during September 2010, March 2011 and September 2011. At the time of data collection, telephone interviews were conducted with individuals in corporations who were customers of the corporate division within the bank. These individuals in their respective corporations were identified and surveyed because they (a) managed the primary relationship of the corporation with the banking division and (b) were senior financial decision makers of their organization’s (i.e. had the ability to influence a decision to change banks). Sample sizes of 273 (September 2010), 259 (March 2011) and 310 (September 2011) individual corporate customers were achieved through a method of stratified sampling. In this study, customers were stratified according to the TB who is responsible for their account. Within each stratum a random sample of 10 – 15 participants were included for each of the 30 TB’s. Monthly revenue data, recorded as a) credit revenue, b) overdraft revenue and c) total revenue was sourced from internal company records for each month from September 2010 to January 2012. Pearson’s correlation coefficient was used to assess whether a positive correlation between the two variables of customer satisfaction and revenue exists. This was followed by Ordinary Least Square Regression to investigate the magnitude and nature of the relationship between customer satisfaction and revenue using customer satisfaction as the independent variable and revenue as the response variable. Cronbach’s alpha was also used for internal scale validity. The results of the research indicated no statistically significant relationship between a customer’s satisfaction with the performance of their TB and either the credit, overdraft or total revenue generated from such a customer through their account. By highlighting this, these findings, nevertheless, contribute to the growing body of knowledge examining the impact of customer satisfaction efforts on revenue. On the basis of the findings of this study, it cannot be practically recommended that customer satisfaction efforts be terminated or changed within the organization of study owing to several study limitations which were present. Firstly, the study was hampered by small sample sizes due to a lack of the availability of revenue data in some instances, particularly in the case of overdraft revenue. Secondly, the study only focused on a single bank account held with the bank and increases and decreases in revenue based on the balances held within that single account. Since one of the purported consequences of improved customer satisfaction is the purchase of additional products, the current design of the study does not take into account the take up of additional accounts or banking products with the bank. Thus, an increase in revenue for the bank as a whole due to the purchase of additional accounts may be masked. Similarly, the scope of the study does not extend to examining the effect of recommendations made by these corporate customers to others and hence growth of divisional or bank revenue due to the addition of new customers. Finally, this quantitative study does not examine revenue growth when compared to customer satisfaction improvements over time due to a limited sample of customers taking part in the study over a number of periods as well as incomplete revenue data. The recommendations for future research are to examine the relationship between changes in customer satisfaction and changes in revenue at divisional level in the long run within the South African banking industry as the impact of an increase in customer satisfaction may be obscured by salient factors in the short run. It is also suggested that future research look at the correlation between dissatisfaction and revenue, where adequate sample sizes are available. Theoretically, the results of this research do bring into serious question the universal application, especially in the context of the South African banking industry of the Service Profit Chain and Satisfaction Profit Chain which propagate the existence of a positive relationship between customer satisfaction and revenue.

  • Description: The economic boom in South Africa following the 1994 democratisation led to increased welfare of the citizens and their purchasing power. This further resulted in increase in electricity consumption. The electricity supply did not increase proportionally to the increase in electricity consumption leading to the 2008 shortage of electricity which nearly damaged the power generating circuit. The literature review has shown that electricity supply and consumption have a positive impact on economic growth. It further showed that employment enhances economic growth. Conversely, it showed that power outages negatively affect economic growth. The research serves to investigate the relationship between electricity supply and economic growth in South Africa and to examine the impact of power outages on economic growth. It also seeks to find the appropriate structure for electricity supply industry that will lead to increase in economic growth. The autoregressive distributed lag (ARDL) bounds approach was used to find the relationship between economic growth, electricity supply, power outages and employment using quarterly data from 2000 to 2012. The ARDL technique was chosen over the conventional models such as Johansen technique for the research because it uses a single reduced form of equation to examine the long run relationship of the variables as opposed to the conventional Johansen test that employs a system of equations. The ARDL technique is also suitable to use to test co-integration when a small sample data is used and does not require the underlying variables to be integrated of similar order. The Vector Error Correction Model (VECM) Granger causality was also employed in the study to establish the causality between economic growth and electricity supply. It was chosen for its ability to develop longer term forecasting, when dealing with an unconstrained model. The results from the ARDL bounds test showed that there is a long run relationship between economic growth, electricity supply, power outages and employment. Based on the causality tests, the findings showed a unidirectional causality flowing from electricity supply to economic growth. This implies that electricity supply affect economic growth in South Africa. The results further showed no causality flowing from economic growth to electricity supply which indicates that when economic growth is booming fewer funds are used for improvement of the electricity generation. Lastly, the results showed that power outages negatively affect economic growth in the long run. To sum up, electricity supply is an important factor for economic growth in South Africa. It is therefore necessary that South Africa must put in place measures aimed at stimulating electricity supply. One of the measures aimed at increasing output of electricity is to unbundle the electricity sector. This process involves allowing entry of the Independent Power Producers (IPPs), Independent System Operator (ISO) and Regional Electricity Distributors (REDs). This will lead to increased supply of electricity and competitively lower prices of electricity. The study further recommends that renewable energy sources should be used to produce electricity instead of coal and nuclear fuels as they failed to produce enough electricity for the nation.

  • Description: A number of authors have portrayed leadership as a vital factor in the success or failure of an organization. Hence Bass (1994; 1997) believes that excellent organizations begin with excellent leadership and organisations reflect their leadership (Maritz, 1995). Therefore, successful organisations reflect their leadership (Maritz, 1995). In an attempt to investigate the aim of this research, various performance and leadership concepts and theories were investigated: the trait concept, behavioural approaches and situational/contingency approaches. Every one of these theories gave a different explanation to leadership. Furthermore, transactional, and transformational leadership were also discussed. The difference between these two models according to Bass and Avolio (1994) is that the work performance of the followers of transformational leadership is usually beyond expectations, while transactional leadership, at best, leads to expected performance. In terms of performance, it is argued that employee work performance can lead to a successful organisational performance. This is because several organisations attribute their business success to the work performance of their employees. According to Collis and Montgomery (1995) employee work performance has a major positive influence on organisational performance. Nevertheless, the accomplishment of an organisation is dependent on the leader’s ability to enhance human resources; hence “effective organisations require effective leadership” (Maritz, 1995). Transformational leadership was identified as the effective leadership style that can motivate workers to improve on their performance by instilling trust and confidence in them. Transformational leadership is superior to both transactional and non-transactional leadership because it makes workers loyal to the mission and vision of their organizations. Bass (1990) states “that the leadership research over the years has proved that loyalty is more powerful than tangible inducements.” Furthermore, non- transactional leaders avoid decision making, allowing their subordinates to take charge of the work process (Bass 1990). This research focuses on the relationship between leadership and employee work performance in a Nigerian Courier Company. In addressing this aim, a Nigerian Courier company was selected as the research context because of its success in the Nigerian turbulent business environment that is plagued by the country’s economic, social, and political troubles (McKern, Meza, Osayande and Denend, 2010). The research hypothesis of this research was generated to investigate leadership and employee performance. Leadership and performance were also identified as the research independent and dependent variables. Thus the research hypotheses were as follows: Hypothesis 1. Null Hypothesis: There is no significant positive linear relationship between employee performance and transformational leadership Alternative Hypothesis: There is significant positive linear relationship between employee performance and transformational leadership Hypothesis 2. Null Hypothesis: There is no significant positive linear relationship between employee performance and transactional leadership Alternative Hypothesis: There is significant positive linear relationship between employee performance and transactional leadership Hypothesis 3. Null Hypothesis: There is no significant positive linear relationship between employee performance and non-transactional leadership. Alternative Hypothesis: There is significant positive linear relationship between employee performance and non-transactional leadership. The general methodology included the use of a valid and reliable instrument known as the Multifactor Leadership Questionnaire (MLQ) and the company’s performance appraisal process. These instruments were used to collect information about employee work performance. The validity and reliability of the MLQ is not in doubt because it was formulated from the full range leadership development theory of Bass and Avolio (1997) and has been used extensively worldwide (Bass and Avolio, 1997). The research data was analysed using Statistica (StatSoft, 2011). Once the data was imported the necessary leadership factors were calculated as per the MLQ scoring key. From the eight factors a further three factors were generated namely transformational, transactional and nontransactional leadership. The data was checked and described using frequency tables and descriptive statistics, followed by correlation matrices coupled with their corresponding scatter plots. The research data was tested for consistency and reliability. Sekaran (2000) states that in order to determine the reliability of a measure one needs to test for both consistency and stability. For this research, linear correlation and regression analysis was used. The outcome of the first investigated hypothesis confirmed that there is a strong significant, positive linear relationship between employee performance and transformational leadership (ρ<0.0001). However, the findings on the null hypothesis, states that transformational leadership has no significant positive linear relationship with employee performance. The null hypothesis is REJECTED, because the model is significant at ρ<.0001. Thus, the alternative hypothesis is ACCEPTED because it concludes that there is sufficient evidence, at the 5% level of significance, that there is significant positive linear relationship between employee performance and transformational leadership. The second hypotheses found that with 5% level of significance there is no significant positive linear relationship between transactional leadership and employee performance (ρ =0.317). It must be noted that since the correlation is not significant the null hypothesis which states that there is no significant positive linear relationship between employee performance and transactional leadership was NOT REJECTED. The outcome of the third hypotheses support the null hypothesis, because the negative linear relationship between employee performance and non-transactional leadership is not significant (ρ = 0.6718). This informed the conclusion that at the 5% level of significance, there is no positive linear relationship between non-transactional leadership and employee performance. The findings of this research favour the conclusion drawn by Brand, Heyl and Maritz (2000) that suggested a more significant relationship between transformational leadership and employee performance, than any other leadership style. Evidence put together in the retail and manufacturing sector of South Africa, and the armed forces of the United States of America, Germany and Canada, point in the direction of the strong, positive effects of transformational leaders (Brand, et al., 2000). Again the effectiveness of transformational leadership can be reinforced by the research directed by Ristow, Amos and Staude (1999), which resolved that the effectiveness of transformational leadership was greater in a South African cricketing environment. Hayward, Davidson, Pascoe, Tasker, Amos and Pearse (2003) conducted research in a pharmaceutical organisation and found a positive linear relationship between transformational leadership and employee work performance. These research outcomes clarify the investigation by Pruijn and Boucher (1994) which established “that transformational leadership is an extension of transactional leadership” (Bass, 1997). The difference between these two models according to Bass and Avolio (1994) is that the work performance of supporters of transformational leadership is usually beyond expectation, while the behaviour of the supporters of transactional leadership, at best, leads to anticipated work performance. This research will be used to improve the relationship between the leaders and employees of the courier company under investigation. It will be useful for the placement of individuals to leadership positions in the company. It will also impact on how future leadership training will be conducted by the company, and of course add to the body of knowledge. This is supported by research conducted in the service sector which states that “transformational leadership affects performance over and above transactional leadership” (Geyery and Steyrer, 1998).
