- Description: Change is inevitable and change is necessary; in order for organisations to remain competitive they have to keep on evolving, ensuring that the organisational vision and strategy are aligned to the organisation’s vision, importantly, that the employees have a fulfilling work experience in order to do their best and live up to the organisation’s values. In the high-pressured, agile work environment, it is necessary for the organisations to move their processes with the times, providing information on digital platforms while upskilling the employees and saving time. Employee engagement is defined as the force that drives the organisational success and when achieved it eventually leads to high morale, employee retention, employee trust and loyalty to the organisation and organisational performance The aim of the study was to investigate the impact of change management process on the employee engagement in the workplace. The three identified main factors were readiness for change, process of change and leadership involvement. Change initiatives have been reported to fail by 70% if not implemented effectively and can have a negative impact on how the employees receive the change. The mixed method study approach was used, starting with interviews with the four key players in the organisation to establish how they perceive change and gather new information. It was followed by a quantitative e-survey to departments which have had technological change in the past year. The empirical results showed that the there is a relationship between the factors of change and employee engagement. Importance of readiness for change was highlighted, supporting the need for an organisational analysis followed by a detailed change plan aligned to the organisational vision. Process of change had a positive significance for employee engagement while lack of leadership involvement showed the negative relationship to employee engagement. The findings show how change leadership should work in sync with organisational leadership at all times and should incorporate change management into the organisational DNA.

- Description: Seabirds are one of the most threatened groups of birds with 29% of seabird species at some risk of extinction. As a result of multiple human-induced threats, seabird species including the Cape gannet Morus capensis which is endemic to southern Africa population experience significant declines and is now classified as Endangered. The Cape gannet faces predation threats from a variety of different species. The current predators of concern at Lambert’s Bay gannet colony are both the Cape fur seal Arctocephalus pusillus pusillus and the Kelp gull Larus dominancus. The former predates on fledglings and the latter predates on eggs. In the 2005/06 breeding season the entire Cape gannet population deserted the Lambert’s Bay gannet colony due to predation by the Cape fur seal. Although the Cape gannets have subsequently recovered to approximately 8000 pairs, seal predation on Cape gannet fledglings continues, together with predation by Kelp gulls. This has caused concern over the impact of predation on this species at the Lambert’s Bay colony, particularly given the species’ conservation status, its small breeding range and its current population trend. CapeNature, the conservation agency involved at this colony has been monitoring and managing the predation on Cape gannets and are interested in evaluating the success of their efforts. Therefore the aim of this study was to determine the spatial and temporal aspects of predation on the Cape gannet population at Lambert’s Bay gannet colony. When examining the influence of fish availability on predation intensity, we found that in years with an increase in fish biomass there was a decrease in predation probability by Cape fur seals. This increase in fish biomass not only led to decreased predation on the fledglings it also led to increased breeding success of the Cape gannets. In determining the effect of predation within the Cape gannet breeding colony we found that the probability of predation by Kelp gulls decreased in years with increased adult gannet density. Indirectly, Cape gannet population growth should lead to a decrease in Kelp gull predation as a higher gannet density increases the risk of injury to the Kelp gulls. This suggests that if Cape gannet populations continue to decline, they may become increasingly vulnerable to Kelp gull predation which can result in a further population decline. In terms of past management actions, the selective culling of predatory Cape fur seals and Kelp gulls, was evaluated. It was found that in the years in which culling of Cape fur seals and Kelp gulls was implemented, a decrease in predation was observed. This indicated that culling reduced predation in the short-term. Predation is inevitable, but due to the Cape gannet’s conservation status we suggest that additional, long-term, and more sustainable methods to reduce predation should be explored. Our research emphasises the need for improving food availability to Cape gannets as food security is paramount to their long-term survival and population growth. Colony management in isolation from other management strategies, is not efficient for conserving a species. We therefore suggest that sound management of predation at the terrestrial habitats are required but that effective management of fisheries are also required for the successful conservation of the Cape gannet. Food security for Cape gannets could be improved by, for example, establishing some ways that we suggest improving the food security for Cape gannets would be to establish Marine Protected Areas (MPAs) with dynamic boundaries around Cape gannet colonies, and to have locate the MPAs close to breeding and foraging hotspots where these areas are closed to fishing thus reducing the competition between commercial fisheries and marine predators, such as the Cape gannet. Another way to improve food security for the gannets are to promote the efforts of focussing on developing and implementing an ecosystem approach to fisheries management in which fishing quotas account for the needs of marine predators. The findings of this study have not only aided the understanding of the dynamics of predation on the Cape gannets and highlighted the extent that predation takes place on them but can also guide future management decisions regarding predation on this endemic and endangered species.

- Description: Ecological studies need to consider ecological interactions between species and their environment across trophic levels. This complexity not only makes the study of ecology very challenging but it also means that ecosystems are vulnerable to change as a disruption at any of the levels could result in cascading effects through the hierarchy. This sensitivity to change makes it especially important to understand ecosystem function as this is needed for effective and adaptive conservation management. A key way in which humans drive and change ecosystem function is through land use and associated management practice. A primary objective of many protected areas is restoration of natural function through re-introduction of large ungulates, which are often fenced and small, thus requiring intensive management that can influence ecosystem function. This is true of the West Coast National Park (the park). Small antelope abundance, and associated drivers, in the contractual Postberg section of the park have been a long-term management question. Postberg is a small (1800 ha) fenced and isolated section of the park which was historically used for agriculture (livestock grazing and some cultivation) and later large wild ungulate species were re-introduced and kept at high densities. The perception of a lower abundance of small antelope has been attributed to predation by a mesopredator (Caracal caracal), however interspecific competition and habitat quality is also known to influence species abundance. Therefore, I aimed to explore the potential mechanisms of small antelope occurrence in the region and how this might differ across three sites with different management practices. Using 18 camera traps, I documented the occurrence of small, medium and large ungulates and caracal. My study spanned across three areas that each represented different forms of management practice with regards to fencing, and stocking rates of managed ungulate species. I made use of single-season, single-species occupancy models in R to assess occupancy of small antelope and caracal and I used the abundance induced heterogeneity model to estimate abundance of managed ungulates. I employed the single-season, two-species occupancy model in PRESENCE to explore species co-occurrence and interactions. Activity patterns and temporal overlap between managed ungulates, small antelope and caracal were assessed using the overlap and activity packages in R. Vegetation height appears to be an important driver of common duiker occupancy. Fallow lands were strongly favoured by managed ungulates suggesting that they may be utilising these patches for foraging. Small antelope occupancy was highest outside of the park and caracal detections were lowest outside of the park. The low detection of caracal across all areas, along with the known diet of caracals, suggests that predation is not likely the driver of small antelope occurrence. Our data suggest that co-occurrence between small antelope and managed ungulates is high and that these sympatric species have probably partitioned food resources. I found that small antelope were mostly crepuscular, managed ungulates more diurnal while caracal were primarily nocturnal. There was a high overlap between small antelope and managed ungulate activity while overlap between caracal and small antelope indicates some temporal partitioning. Overall I found some effects of inter-specific interactions at the local scale. There was, however, no consistent pattern across the areas which, in line with literature, suggests large scale ecological trends are difficult to detect at local scales. Due to the heterogeneity of the region’s vegetation, coupled with the small size of the biome and extensive fragmentation by land use, there are few areas which adequately represent the biome to test how large ungulates would utilise the area at a large scale. This has important implications for the management of small protected areas in the region who are mandated to restore these areas to their historical and natural function. The ability of conservation managers to meet objectives of restoring parks to their historical function, and maintaining these systems as such, may be questioned if our protected areas are not meeting the spatial requirements of re-introduced species.

- Description: This cross-sectional quasi-experimental research applied a combination of an indepth literature review, key informant interviews and a small- and medium-sized enterprise (SME) survey to identify key policies which influence access to formal finance for women-owned SMEs in Zimbabwe. The study then applied Sandiford and Rossmiller’s 4Es (effectiveness, efficiency, enforceability and equity) framework for policy analysis to identify gaps in the SME development policy framework, which inhibit female entrepreneurs from access to formal finance. The study also reviewed India’s SME development policy framework to identify lessons that Zimbabwe could learn. The study found that female entrepreneurs in Zimbabwe are rarely engaged during the design and implementation of SME policies; hence they lack knowledge of interventions which affect their businesses. The study also found that Zimbabwe lacks current data and knowledge on how the current SME policy framework affects women-owned SMEs to access finance. As a result, SME policies are not evidence based, are hurriedly implemented and lead to duplication and uncoordinated efforts. In addition, SME policies are not systematically evaluated so as to better inform implementation thereof or follow on policies. The study concluded that Zimbabwe’s SME development policy ranks low on all the 4Es - effectiveness, efficiency, enforceability and equity in promoting access to finance for women-owned SMEs. The study recommends the Government of Zimbabwe (GoZ) to invest in timely policy research and analysis to better understand women-owned SMEs’ access to finance challenges and adopt evidence based policy making and implementation. The study also recommends the GoZ to learn from India how to enhance the SME development policy framework by building the capacity of female entrepreneurs and financial institutions to close the deeply entrenched information and confidence gaps on access to finance issues.

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

- Description: The small business sector is growing rapidly worldwide. It has been noted that the small business sector plays a vital role in the social as well as the economic development of the country. However this has brought about some challenges with regards to tax compliance. Within the Eastern Cape there is a vast difference in customer base, with some taxpayers being illiterate the non-compliance challenge becomes rather a critical focus. The limited tax knowledge within the small business sector as well as the complex tax language has contributed to small businesses being tax non-compliant. It is for this reason that this study became apparent. The primary objective of this study is to identify the variables to improve tax compliance for the small business segment by investigating the determinants of effective communication. More specifically this study will investigate the influence of communication channels, communication frequency, Information Technology Communication and tax education on tax compliance. To achieve the primary objective of this study, secondary and primary research was undertaken. The positivistic research methodology was adopted as relationships were tested as well as it emphasised the quantification of the data collected and analysed. Four determinants of effective communication (Communication Channels, Communication Frequency, Information Technology Communication and Tax Education) served as the independent variables, while Perceived Success of Tax Compliance served as the dependent variable. The majority of respondents were females with a 61% representation and males represented 39% of the responds. Most respondents were between the ages of 36 and 45 years, the age group profile depicts the diversity of the maturity levels within the respondents. From the descriptive statistics it was observed that the majority of the respondents agreed that their businesses were tax compliant. For the independent variables, the reported average mean values ranged from 3.03 to 3.97 with the highest mean value being reported for the variable of Tax Education and the lowest score reported for Communication Frequency. In accordance with the literature review and the findings from the empirical data obtained and analysed in this study, it can be concluded that tax compliance is a function of many variables. The study has revealed that the determinants of effective communication that were identified as independent variables have an impact on the perceived success of tax compliance. In other words, an increase in the independent variable will lead to an increase in the level of tax compliance.

- Description: The legal principles of reasonableness and the burden of proof date back to ancient times. The first codification of these principles occurred in Roman Law. The Tax Administration Act incorporates these principles in various sections. The purpose of this treatise as formulated in Chapter 1 was to determine whether there is a close connection (in practice) between tax administration (within the context of the Tax Administration Act) and the principles of reasonableness and the burden of proof. SARS acknowledges that the principles of best international practice in tax administration must be taken into account1. These principles include equity, fairness, certainty, simplicity, efficiency and effectiveness. Effective tax administration entails that a balance must be struck between the rights and obligations of the taxpayers and those of SARS2. It is important that the taxpayers and SARS strive to communicate with one another in an efficient and effective manner in order to resolve disputes between them. The treatise followed a logical approach. This entailed that the general interpretation of aspects had to be followed by the tax specific interpretation of the aspects. The general interpretation included an analysis of case law as well as research into the origins of the principles of reasonableness and the burden of proof. Reasonableness and the burden of proof do not require perfection. It is important, however, that assertions must be accompanied by evidence. The quality and quantity of evidence submitted is dependent upon the relevant facts and circumstances of a matter. The facts and circumstances of a matter also constitute determining factors in 1 Draft Explanatory Memorandum on the Draft Tax Administration Bill, 2009 at 1 in 2.5. 2 Ibid in 2.1.evaluating whether the principles of reasonableness and the burden of proof have been applied. The treatise concludes that increased efforts are necessary in order to ensure that the principles of reasonableness and the burden of proof are adhered to in tax administration. This obligation is not limited to SARS but also includes taxpayers and tax practitioners. This is closely linked to effective and efficient communication.

- Description: Cancer procoagulant (CP) is a cysteine protease found in tumour cells and amnion chorion membranes. The main function of CP is not yet known, but it has potential roles in tumour growth and metastasis. Initially, CP was believed to increase coagulation in cancer patients; however, research has shown that increase in CP concentration does not correlate with an increase in coagulation. The location of CP in amnion chorion membranes and tumour cells only led to the hypothesis that CP might be involved in inducing blood vessel and or lymph vessel formation. CP was shown to induce lymphangiogenesis (lymph vessel formation) in human telomerase reverse transcriptase-human dermal endothelial cells (hTERT-HDLEC) (Tshaka, 2011). CP-induced tube formation was inhibited by rapamycin; indicating that CP may be signalling via the mammalian target of rapamycin (mTOR) pathway. The aim of this study was to investigate the effect of CP on the mTOR signalling pathway using human umbilical endothelial vein cells (HUVECs) as a model. CP was isolated from amnion chorion membranes and purified using two anion exchange chromatography steps. Purified CP (2 μg/ml) was used to induce tube formation in endothelial cells (HUVECs) seeded on growth factor reduced (GFR) Matrigel. In addition, the 2 μg/ml CP was used to treat cultured HUVECs. Sodium dodecyl sulphate polyacrylamide electrophoresis (SDS-PAGE) and western blotting were used to determine phosphorylation levels of protein kinase B (Akt) and ribosomal protein S6 kinase (S6K). CP was successfully isolated and purified using anion exchange chromatography. The effect of CP on tube formation was not significant relative to the control in the HUVEC cell line. The role of CP on Akt and S6K phosphorylation still needs to be verified by using sensitive methods of quantification such as enhanced chemiluminescence (ECL) and enzyme linked immunosorbent assay (ELISA). The levels of CP activity were shown to be higher in early tumour growth than in advanced cancer suggesting that certain physiological factors could be increasing CP activity during early tumour growth. This study investigated the effect of cobalt chloride on CP activity in breast cancer cell lines. Cobalt chloride reduced CP activity in MCF-7 and promoted CP activity in MDA-MB-231.
