Knowledge about personal branding, the development and sustaining of a personal brand and the link between personal branding and career success did not exist in a scientifically structured manner. The purpose of this study was to understand what the elements of personal branding are and what it takes to develop a personal brand in the corporate environment. It was also important to identify whether personal branding is key to career success. The systematic literature review procedure was used to identify, analyse and critically evaluate both empirical studies and popular literature relating to personal branding. The current body of knowledge was ill defined and a six step model detailing how to develop and maintain a personal brand was developed as a result of a content analysis of the available popular literature. A measure of a complete personal brand within the workplace was subsequently developed. In this study, the hypotheses of a possible relationship between personal branding and career success (performance appraisal score, 360 leadership evaluation and talent board placement) were tested. It was found that talent board placement was statistically significant and practically related to personal branding. The study was the first to provide a measurement tool as well as empirical evidence on the relationship between personal branding and career success and, as such contributed significantly to the body of knowledge. This study also opened avenues for further research. / Daar was min kennis oor ’n persoonlike handelsmerk, die ontwikkeling en handhawing van ’n persoonlike handelsmerk, en die verband tussen ’n persoonlike handelsmerk en loopbaansukses in die wetenskaplike domein beskikbaar. Die doel van hierdie studie was om die elemente van ’n persoonlike handelsmerk te begryp, asook om te bepaal wat dit behels om ’n persoonlike handelsmerk in die korporatiewe omgewing te ontwikkel. Dit was ook belangrik om te bepaal of ’n persoonlike handelsmerk deurslaggewend is tot loopbaansukses. ‘n Sistematiese literatuuroorsig is gedoen om empiriese studies asook gewilde literatuur oor ’n persoonlike handelsmerk te identifiseer, te ontleed en krities te evalueer. Gegewe beperkte akademiese kennismateriaal, en na aanleiding van die inhoudsontleding van die beskikbare gewilde literatuur, is ’n sesstapmodel ontwikkel om aan te dui hoe ’n persoonlike handelsmerk ontwikkel en gehandhaaf kan word. Na aanleiding hiervan is ’n instrument ontwikkel om ’n person se handelsmerk omvattend in die werkplek te meet. Dit is gevolg deur hipoteses van ’n moontlike verband tussen ’n persoonlike handelsmerk en loopbaansukses (prestasiebeoordelingtelling, 360-leierskapevaluasie en talentplasing) te toets. Die studie het bevind dat ’n persoonlike handelsmerk statisties beduidend en prakties relevant is tot talentplasing. Hierdie navorsing lewer ’n omvattende meetinstrument vir die meting van ’n persoonlike handelsmerk, asook empiriese bewyse rakende die verhouding tussen ’n persoonlike handelsmerk en loopbaansukses.

Abstracts in English, Zulu and Xhosa / Rock art affords unique opportunities for engendered research because it provides emic views of how specific people re-presented themselves. My feminist study investigates under-researched ‘San/Bushman’ gendered identities to understand more about area-specific constructions of personhood through analysing 2852 rock paintings from two adjacent areas of the northern Eastern Cape, South Africa. Using quantitative and qualitative methods and evidence from excavation archaeology, ethnography, ethology, and neurocognitive research, I identify three categories of ritual specialists: experienced and preeminent; ordinary; and novice. These paintings show that wo/men ritual specialists could transcend the identity norms of ordinary people, but men ritual specialists may have had more status and power. I suggest the paintings acted as a controlling mechanism for the potency of women, indoctrination of novices, and present an ideal for the practice of ritual specialists and ordinary people. This research has important implications for identifying different types of identity marking by different groups of southern African San. / Bonono ba majwe bo fana ka menyetla e ikgethang bakeng sa dipatlisiso tse fokolang hobane e fana ka ditjhebo tsa bonnete tsa hore na batho ba itseng ba ne ba itlhahisa jwang.

South Africa, like many other developing countries, faces a growing problem of informal settlements which are mushrooming in and around the major urban centres. Living conditions within these settlements are typically poor with residents facing a range of basic livelihoods challenges, exacerbated by poverty, inequality and social exclusion. Unplanned and rapid urbanisation, from which informal settlements originate, and existing conditions in these areas, heighten risk to disaster and provide the conditions that turn natural and man-made events into major livelihoods disruptions. The most devastating of these disruptions are disasters brought on by uncontrolled fires, extreme wet weather and associated flooding. To forestall disaster, minimise livelihoods disruptions and debilitating loss of assets, and safeguard developmental progress, local governments have increasingly adopted risk reduction approaches to their development planning and implementation. Among some of the critical risk reduction measures adopted is the deployment of communication interventions meant to cultivate a culture of risk avoidance among at-risk communities. While it is largely accepted that developmental losses can be considerably reduced if people are properly educated and well-prepared for a disaster, it is also widely recognised that current tools and guidelines for communication of disaster risk in developing communities have largely proved inadequate. Among leading criticisms is that the communication interventions implemented neither fully cater for the contemporary proactive and pre-emptive (risk minimising) approach to disaster risk management nor the developmental imperatives of the disaster risk reduction paradigm. This study, therefore, sought to propose a conceptual framework for the reorientation of thinking and improvement of the on-the-ground practice of disaster risk communication in South African municipalities, and to ensure, among other things, that the practice of disaster risk communication in South Africa places participation of at-risk communities at the centre of communication interventions for disaster risk reduction. A literature study was conducted to explore what principles of the participatory approach to development communication could be applicable to a framework for disaster risk communication interventions. Following the literature study, an empirical study into the contemporary disaster risk communication practice in the three study sites of Cape Town, George and uThungulu District was carried out. The field study comprised semi-structured interviews with disaster risk communication managers and other key informants, and focus group discussions with members of informally settled communities in the study areas. Using a hybrid thematic analytic approach, the data gathered empirically were analysed against the salient themes derived from the literature study and those emerging as the empirical study progressed, and from that process a conceptual framework for disaster risk participatory communication for at-risk communities in South African municipalities was developed and proposed. In conclusion, guidance was also given for translation of the conceptual framework into actual practice by disaster risk managers and other disaster risk reduction role-players in South Africa. / PhD (Communication Studies), North-West University, Potchefstroom Campus, 2014

This dissertation focuses on Foreign Direct Investment (FDI) in the oil sector of Africa, more specifically in Nigeria and Angola. A large problem faced by most African countries is their low domestic investment. This is due to the low savings rates in these countries. FDI serves as a supplement to domestic investment and therefore allows for increased production and growth in the region that can ultimately lead to better development. Further, FDI brings forth positive spill over effects that can further increase levels of development in African countries. Therefore, it is beneficial for African countries to achieve higher levels of FDI inflows. The African oil sector has, in recent years, received much deserved attention as Africa supplied approximately 11 percent of worldwide oil supply and the African untapped oil reserves constitute approximately 10 percent of the total worldwide proven oil reserves in 2010. There are currently 19 African countries known to have significant oil reserves and further surveying may increase this number. This dissertation focuses on Nigeria and Angola as these countries are the continent’s largest producers of oil and their oil sectors are the sectors with the strongest FDI inflows. Through economic and policy reforms and increased share in global oil supply, it is believed that these countries can be the drivers of economic growth and development in the region. Greater FDI is needed to fully exploit the available oil resources. Although many studies have been done on the factors that attract FDI, very few studies have focussed on oil sector specific FDI. Therefore, the aim of this dissertation is to determine and compare the factors that attract oil sector FDI in Nigeria and Angola. This dissertation undertakes both a literature review and an empirical analysis. The literature review provides an overview of FDI theory, the motives for investment, the types and benefits thereof; an overview of the African and, more specifically, the Nigerian and Angolan oil industry and the influence that FDI inflows have had on this sector. The current FDI inflow trends and oil sector FDI in Nigeria and Angola are reviewed. The dissertation examines and compares the current state of the Nigerian and Angolan oil industries. The empirical analysis consists of a country comparison through four least square regression models (domestic models for Nigeria and Angola and global models for both countries) using data between 1990 and 2011 obtained from the World Data Bank and the 2012 BP statistical review. The data used will describe the traditional determinants of FDI inflows as set out in literature review and other determinants derived from past studies of FDI inflows in transitional economies and oil sector dependent countries. In Nigeria and Angola, the problems of lack of accurate and sufficient data over a longer time period persist, as they do in most African countries. The main findings are that significant domestic influences of FDI inflows in Angola include: lower public power to entice private gain; better policies that are effectively enforced to improve civil and public services; and the proven oil reserves. This entails that government policy, transparency and their oil reserves are held in high regard by the foreign investors in Angola. In Nigeria, however, domestic influences of FDI inflows include: better citizen ability to select a government; freedom of expression; freedom of association and a free media; better ability of the government to formulate and implement sound policies and regulations that permit and promote private sector development; and oil production. This indicates that democracy, government policy and oil production are highly regarded by foreign investors who invest in Nigeria. Therefore, it can be argued that, even though results for factors influencing FDI inflows differ, there are similarities as government policy and the oil sector in general influence both countries even though the issues in both countries are not necessarily the same. However, on a global level, investment in the two countries is driven by completely different factors. According to the models, Angolan FDI inflows are driven by global oil production (supply) in the previous year whereas FDI inflows in Nigeria are correlated to the oil price in the previous year. Both of these models, however, leave much to be desired as they have low R2 values which indicate that they explain very little of what influences FDI inflows in the countries. / MCom (International Trade), North-West University, Potchefstroom Campus, 2014

Gas exploration and production at sea and on land is a recent phenomenon in South Africa. The reason for the sudden interest in gas exploration and production on land is that it may prove to be a solution to the need for cleaner forms of energy and provides the possibility for South Africa to move away from coal-based energy. In order to achieve this transition while keeping economic development intact, South Africa is in need of a “greener” option. Gas is considered the most environmentally friendly fossil fuel and therefore provides South Africa with this much needed “greener” option. The uncertainty about the nature and extent of the environmental impacts regarding gas exploration and production suggests that an efficient and effective energy and environmental law and policy framework is still needed to regulate onshore and offshore gas exploration and production during all phases of its life cycle. It furthermore requires of the authorities that they establish and enhance environmental protection and sustainability during all gas exploration and production operations in order to ensure that the environmental impacts that may occur during such operations are addressed in a holistic and integrated manner. This study focuses on conventional gas. South Africa’s energy and environmental law and policy framework that regulates gas exploration does not cover the entire life cycle of onshore and offshore gas activities. It is of paramount importance that the current fragmentation in the country’s existing energy and environmental regulatory framework be addressed and that a sufficient environmental governance regime, as envisaged in this study, is established. This will enable the administering agents to actively promote and maintain the welfare of the people, the ecosystems, the essential ecological processes and the biodiversity of South Africa, while promoting the utilisation of living natural resources on a sustainable basis to the benefit of all South Africans, present and future, as pledged in the Constitution of the Republic of South Africa, 1996. / LLM (Environmental Law and Governance), North-West University, Potchefstroom Campus, 2014

Afrikaans speaking believers have been experiencing a degree of disillusionment due to changes in the South African political landscape. This has caused spiritual instability that again caused people to want to escape to beter opportunities elsewhere, reduced church attendance and social isolation. This disillusionment is due to the fact that Afrikaans speaking believers hold to a cultural, social and self empowering type of hope that looks to the advantages of positive circumstances. A great void exists in research dealing with the hope and spirituality of Afrikaans speaking believers who experience such a disillusionment, and that resulted in this study. An empirical study revealed that the Afrikaans community struggles to deal completely with the new South African community. They feel the pressure of limited or no work opportunities due to affirmative action, uncertainty regarding their role in the new South Africa and the breaking down of Afrikaans as a historically respected language and culture. Materialism, a false trust in political and world leaders, negative media reporting, as well as people immigrating for beter opportunities, were singled out as contributors to the breaking down of hope, a hope that takes on the form of cultural entitlement and social self empowerment. A literary study showed that true Christian hope must be distinguished from wishful thinking, the outcome of social, political or economical self empowerment or emotional optimism, but rather that it is grounded in the faith knowledge of Jesus Christ as Redeemer. The church as the family of God provides hope in a space where the past and the future comes together in an active walk of faith that follows the life of Jesus Christ in serving and caring for others. Preaching must be the carrier of hope and the reminder that the promises of God will be realized up and until the coming of Jesus Christ in glory. Perspectives from Scripture confirmed that hope is not just a human thought of wishful thinking, an emotional state of mind or optimism. True Christian hope is an inner faith conviction and trust in the promises of God for salvation, provision and grace, even in the midst of poor or bad circumstances, caused by sin. This Christian hope is initiated and developed through a knowledge of the Word of God, that finds fulfillment in Jesus Christ. True Christian hope is an inner spiritual conviction through faith in Jesus Christ, a practical lifestyle of love in accordance with God’s will and a living expectation for the coming of Jesus Christ. Practical-theoretical guidelines and study work were developed where Afrikaans speaking believers, experiencing a degree of disillusionment due to a changing South Africa, can be pastorally guided to a true Christian hope. / MA (Pastoral Studies), North-West University, Potchefstroom Campus, 2014

The De Witte (2000) Job Insecurity Scale (JIS) claims to measure the cognitive and affective dimensionalities of job insecurity. However, there is a concern as to whether this is in fact a true reflection of the individual, owing to the possibility that the JIS may rather measure the negative and positive dimensionalities of job insecurity instead. This research article aims to investigate whether a revised version of the JIS measures the cognitive and affective dimensionalities of job insecurity, or alternatively, other dimensionalities of the revised JIS after additional items have been added to the scale. Furthermore, it is aimed at determining whether the constructs of the revised JIS prove to be invariant across gender, age and educational level, and to determine whether the psychometric properties of a revised version of the JIS is a valid and reliable instrument. Furthermore, this research article aims at determining if the revised version of the JIS is a more accurate indicator of job insecurity and its relation with organisational outcomes (job satisfaction and organisational commitment), as well as its equivalence across various demographic variables (i.e. gender, age and educational level). A quantitative research approach was used. This approach was utilised to statistically reflect the psychometric properties of the revised version of the JIS, using large amounts of data relating to job insecurity. A cross-sectional design was used for the purpose of this study. The sample consisted of employees working in the mining sector (n = 262) and manufacturing industries (n = 208), constituting a total sample of 470 (n = 470). Non-probability quota sampling was used to adequately divide the population according to its sector in the economy, and further according to the industry. The results showed that the revised JIS consists of a two-factor model, namely job security and job insecurity. Furthermore, it was found that the revised JIS is valid in providing relationships with organisational outcomes (job satisfaction and organisational commitment). The study indicated that job insecurity has a negative relationship with job satisfaction, as well as a predictive positive relationship with organisational commitment. The revised JIS proved to have discriminant validity in that it does not relate to an unrelated construct (physical tiredness during work). Lastly, the revised JIS can be deemed valid across different demographic groups (gender, age and educational level). Recommendations are made to be applied in practice, as well as for future research. / MA (Industrial Psychology), North-West University, Potchefstroom Campus, 2015

Background: Research on nursing practice has highlighted a relationship between non-nursing tasks (NNTs), nursing tasks left undone (NTLU), and internationally it was found that these factors have an effect on job satisfaction. Since the last study done on NNTs and NTLU in 1988, much has changed in South Africa`s health system. Current South African studies have revealed that decreased numbers of PNs in South Africa experience satisfaction. Therefore, this study explores the relationship between NNTs, NTLU and job satisfaction on both individual PN level and unit level in South Africa, and contributes to the international debate. Aim: To investigate the relationship between NNTs, NTLU and job satisfaction among professional nurses (PNs) in medical and surgical units in private and public hospitals in South Africa. Method: A cross-sectional survey design was used including 1166 PNs in 60 medical and surgical units in 55 private hospitals and seven national referral hospitals in South Africa who completed the survey. Measures: Relationships between NNTs, NTLU, job satisfaction and aspects of job satisfaction. Results: The three main NNTs performed were filling-in for non-nursing services (d=0.47), cleaning patient’s rooms and equipment (d=0.48) and obtaining supplies and equipment (d=0.64). Nationally more than 50% of PNs reported the following NTLU – comfort/talk with patients (62.2%), educating patients and family (57.9%) and develop or update nursing care plans/pathways (51.6%). PNs in private hospitals are more satisfied with their jobs than PNs in public hospitals. PNs were most dissatisfied with the opportunities for advancement (M = 2.60) and educational opportunities (M=2.64) aspects of job satisfaction. At unit level, NTLU positively correlated with three NNTs, and job satisfaction correlated mostly and negatively with NTLU. Conclusion: South African PNs perform many NNTs. However, the performance of NNTs does not influence their job satisfaction to the extent the NTLU does. Although PNs in this study indicated that NNTs do not have a significant influence on NTLU, it may reveal a greater issue, in that PNs have grown accustomed to performing NNTs as part of their workload. Clarifying professional nurses’ scope of practice and increased use of support services may provide PNs with more time to conduct nursing tasks which should improve job satisfaction. Recommendations for practice, education, policy/orientation programmes and research are made from the findings of this study. / MCur, North-West University, Potchefstroom Campus, 2014

Motivation: C-reactive protein (hs-CRP) and other risk factors such as cortisol and obesity in the diagnosis of cardiovascular dysfunction (CVD) in African and Caucasian women has become increasingly imperative when one considers the escalation of hypertension among these groups. Recent studies have explored some aspects of these risk factors and the roles that they play within hypertension and possible future risk for cardiovascular disease. Hs-CRP has been associated with the increased prevalence of hypertension and obesity. Cortisol per se has also been linked with the development of both hypertension and the hypothalamic-pituitary adrenal cortex (HPA) response. Nevertheless, the exact mechanism remains rather uncertain due to conflicting outcomes of research within different ethnic groups. Several recent investigations have, however, linked hypocortisolism with both urbanisation and a subsequent increased likelihood of hypertension within African women as they have presented increased vascular blood pressure responses. Conversely, Caucasian women have displayed an increased central cardiac reactivity. The lack of data regarding the relationship between the above-mentioned parameters within both African and Caucasian women serves as the motivation for conducting this study. Objective: To investigate hs-CRP, cortisol and hypertension as contributors to the increased likelihood of cardiovascular dysfunction in both African and Caucasian women within South Africa. hs-CRP use this through whole document please Methodology: The manuscript presented in Chapter 2 has been compiled using data obtained from the POWIRS (Profiles of Obese Women with Insulin Resistance Syndrome) study. Apparently healthy African (N=102) and Caucasian (N=115) women, matched for age and body mass index, were recruited from the North-West Province of South Africa for participation within this study. Subjects were divided into normotensive (NT) and hypertensive (HT) groups according to the mean resting cardiovascular values that were taken using a Finometer device. High-sensitivity C-reactive protein (hs-CRP) and cortisol blood serum values were determined by immunochemistry and ELISA analyses. Significant differences within each ethnic group and between each of the groups (NT and HT) were determined by analysis of covariance (ANCOVA), for anthropometric, cardiovascular, hs-CRP and cortisol variables, while adjusting for cardiovascular covariates (age, smoking and alcohol consumption). Partial correlations analyses were used to examine the relationship between hs-CRP, cortisol, anthropometric and cardiovascular parameters adjusting for cardiovascular covariates. Logistic regression analyses was used within each ethnic group to determine the relationship between anthropometric, cardiovascular, hs-CRP and cortisol as independent variables and hypertension as dependent variable. This study was approved by the Ethics Committee of the North-West University and all subjects gave informed consent in writing. For a more detailed description of the subjects, study design and analytical procedures please refer to the Materials and Methods section within Chapter 2 of this dissertation. Results and Conclusion: Both ethnic groups presented higher hs-CRP and lower cortisol levels compared to normal values. Lower waist circumference (WC) and cortisol as well as higher blood pressure (BP) and vascular values were evident in Africans compared to Caucasians. Both HT ethnic groups were older and more visceral obese compared to their NT counterparts. HT Caucasians indicated higher central adrenergic responses whilst HT Africans showed vascular adrenergicresponses. Only NT Africans had lower cortisol values than NT Caucasians but the Africans (NT and HT) responded with higher diastolic blood pressure responses compared to their Caucasian counterparts. Moreover, hs-CRP within African women significantly correlated with all BP and obesity variables whilst hs-CRP only associated with stroke volume (SV) and compliance (Cw) within HT Caucasian women. Cortisol in both ethnic groups was strongly associated with vascular BP responses. Only BP contributed to the higher prevalence of HT in both ethnic groups. In conclusion, these results suggest the possible diverse roles of HPA axis dysregulation associated with higher inflammatory responses. This happens in conjunction with cardiac and vascular responses within more obese Caucasian and especially African women, respectively. / MSc (Physiology), North-West University, Potchefstroom Campus, 2009

The study of pneumatology is important and necessary in theology, and also in the church. What Christians have to know and understand about it must be taught clearly. The nature and work of the Spirit of God should be mastered by every believer in Jesus Christ. In this way, wrong concepts and teachings can be rejected by the Christian way of life, in the church especially in Africa. It is very noticeable that Africans, in their traditional worldview are conscious of the existence of the Supreme Being, spirits, divinities, ancestral spirits and the spiritual world with its diversity. Africans, Christians and non-Christians believe that around them there are invisible spiritual beings and because of this consciousness they are haunted by the wish to discover what is really going on in the invisible world of the spiritual realm. Most Africans consider the existence of the ancestral spirits as a very important matter and they are in daily need to consult them about every event happening among them in their traditional context. In every event they believe there is always somebody, meaning a spirit, behind what is happening. A death or an accident cannot happen without having been caused by a spirit especially an ancestral spirit. The ancestral spirits are thought to be active in the lives of their living descendants on earth. Ancestral spirits are ambivalent in their relation with the living. They can bring good things to their descendants if they are well treated. They harm and molest them when they are angered by their descendants. The fact that Africans have been confronted with the Gospel has had an impact on the lives of Africans. We have to acknowledge that many things in the conduct of African culture have changed or are going to change in the practical lives of Africans. Although the Gospel has had an impact on the people in Africa, it is unfortunately observed that some Africans do not manifest real change. Christian Africans, despite this encounter with the Christian faith, usually revert to traditional practices in case of hardships like accident, incurable diseases and barrenness, for example. The context of religious pluralism which Africans are experiencing, presents an open door to syncretism. Traditional practices are seriously against the biblical teaching and practices. Christians in the church are found (many times) to be involved in these traditional practices where they fear the attacks of their ancestral spirits or the misfortunes by other spirits. The Spirit of God is active in the world and also in Africa. Christians have to rely on God and not on their ancestral spirits for the sustenance and support in different domains of life. The solution to this on-going attitude of Africans to the spirits can only come from the Word of God. It is absolutely important to continue with the proclamation of the Gospel to Africans. This proclamation of the Word of God must be taken seriously by the church and Christians in Africa. It is only the message from the Bible that can free Africans from their belief in the ancestral spiritual world. / PhD (Dogmatics), North-West University, Potchefstroom Campus, 2015
