- Description: The study explores and compares the incidents of vigilantism in two selected communities in Port Elizabeth. However, the word ‘vigilantism’ as utilized in the study can be explained as the group of people in a community who take the law into their own hands and punish alleged societal offenders on the spot. Vigilante activities have become a regular occurrence in many communities in Port Elizabeth and in South Africa as whole. This phenomenon as reported by several authors has destroyed many young men’s lives and ambitions. This is a paradoxical situation that violates human rights because South Africa is a country with a Constitution that prioritizes human dignity for all, and citizens that are totally free from violence of any kind. The aim of the study is to explore, analyze and compare the incidents of vigilantism in New Brighton and Kwazakhele communities in Port Elizabeth. The intention is to educate and enlighten the members of the selected communities, together with the public about vigilantism and its impact on communities.

The intention is to educate and enlighten the members of the selected communities, together with the public about vigilantism and its impact on communities. The researcher achieved the aim of this study by asking the following questions: • What are the motives of individuals/communities who take the law into their own hands? • What impact do vigilante incidents have on communities? • Which effective preventative measures can be utilized to combat vigilantism? To answer these questions, questionnaires for data collection were utilized. The study was conducted using a total population of one hundred (100) participants who were divided by two. Each community had a sample of fifty (50) participants. The participants were selected by utilizing purposive sampling technique which is non-probability sampling. The participants were the community members of the selected communities. The researcher applied a qualitative research methodology in order to obtain in-depth information and utilized content thematic analysis and SPSS software for the analysis of the data gathered. Two theories a) Differential Association Theory and b) Social Learning Theory were employed to interpret the findings of the study. iv The results of the study demonstrate that there has been an escalation in vigilante activities in Port Elizabeth communities since 2000 and 2010. In many vigilante actions that occurred, males (ages between 18 and 30 years) were found to be the majority of the people who were more likely to be victims of vigilantism because of the crimes they commit. The results also demonstrate that an increase in vigilante incidents in New Brighton and Kwazakhele have been reported to be a result of the ineffectiveness of visible policing, easy bail conditions and frustration and anger of the community members, who do not see the criminals being arrested. These vigilante activities have been reported to have negative impact in these communities specifically on children. Based on this issue of vigilantism, several strategies that could assist to combat vigilante actions were made. The participants suggested that government should improve the criminal justice system as a whole in order to reduce vigilantism. The respondents also indicated that government should create jobs for the youths because other people become involved in criminal activities, because of poverty and lack of employment opportunities. Furthermore, the participants proposed that government should enact tough laws on offenders. v.

- Description: This work presents the synthesis and characterization of a new zinc phthalocyanine complex tetrasubstituted with 3-carboxyphenoxy in the peripheral position. The photophysical properties of the new complex are compared with those of phthalocyanines tetra substituted with 3-carboxyphenoxy or 4- carboxyphenoxy at non-peripheral positions. Three phthalocyanine complexes were encapsulated within silica matrix to form a core shell and the hybrid nanoparticles particles obtained were spherical and mono dispersed. When encapsulated within the silica shell nanoparticles, phthalocyanines showed improved triplet quantum yields and singlet oxygen quantum yields than surface grafted derivatives. The improvements observed could be attributed to the protection provided for the phthalocyanine complexes by the silica matrix.

- Description: The search for cheap, non toxic and readily available antidiabetic drugs has been a challenge for researchers and the pharmaceutical industries. Diabetes mellitus is a metabolic disease characterized by defects in the synthesis of insulin and/or insensitivity to the action of insulin at the target cells. The disease has been on the increase mostly in developing countries where large proportions of the population have little access to good medical care due to either accessibility or non availability of synthetic drugs. This has led to the use of medicinal plants to treat diabetes because it is safe, cheap and with few side effects. There is little scientific evidence on the dosages, active compounds, mechanisms of action and toxicity of these traditionally used plants. Two of the most frequently used plants; Albuca setosa and Albuca bracteata were investigated in this study. The qualitative analysis of different extractions of these plants revealed the presence of phenolics, alkaloids, tannins and saponins. The antioxidant properties of aqueous, acetone and methanollic extracts of Albuca setosa and Albuca bracteata were investigated using models such as Diphenyl-1-Picrylhydrazyl (DPPH), 2, 2’-azino-bis (3-ethylbenzothiazoline-6-sulphonic acid) (ABTS), Ferric ion reducing antioxidant potential (FRAP), Nitric Oxide and Hydrogen Peroxide (H2O2). Both plants revealed inhibitions against DPPH in a concentration - dependent manner with Albuca setosa (0.330 mg/ml) showing higher activity than Albuca bracteata (0.647 mg/ml) determined from the IC50. The aqueous extract of Albuca setosa showed a higher inhibition against DPPH radical compared to the Albuca bracteata aqueous extract at all concentrations investigated. The isolated saponins from Albuca bracteata had a higher DPPH scavenging activity than the crude methanolic extract of the plant in a concentration - dependent manner but are significantly different from each other at 0.4, 0.6 and 1.0 mg/ml only. The IC50 of the saponins was also observed to be higher than the crude extracts and standards.The Albuca setosa aqueous extract showed a higher percentage inhibition of ABTS radicals than Albuca bracteata at all the concentrations investigated. Overall, the Albuca setosa aqueous extract (0.0809 mg/ml) showed maximum activity against ABTS radicals. The iron reducing power was significantly higher (P < 0.05) in the methanolic extract of both plants compared to the aqueous counterpart. Overall, the Albuca bracteata aqueous extract (0.344 mg/ml) showed maximum activity as indicated by the IC50. The aqueous extracts of both plants also revealed percentage inhibitions in a concentration - dependent manner against NO2. The aqueous extract of Albuca bracteata bulb was more active against nitric oxide and hydrogen peroxide inhibition. In this study, the cytotoxicity of the extracts was evaluated at a high dose of 100 μg/ml on Chang liver cells and determined using MTT, crystal violet, glucose consumption, lactate production and lactate dehydrogenase release and FRAP. The aqueous extracts of both Albuca setosa and Albuca bracteata were non-toxic on Chang liver cells at the concentrations investigated. The MTT revealed that the aqueous extract of Albuca setosa bulb had the optimum cell viability of 108.09 percent while the acetonic extract of Albuca bracteata showed the least cell viability (37.72 percent) compared with the control. The crystal violet test also revealed the acetone extract of Albuca bracteata to have the least percentage of cell viability at 31.47 percent, while the aqueous extract of Albuca setosa showed the maximum cell viability at 112.5 percent. The aqueous extracts of both plants showed higher percentage cell density on the second day of incubation from the proliferation assay. All the tested samples were observed to consume more glucose than the blank except for the methanollic and acetone extracts of Albuca bracteata bulb. The aqueous and methanolic extracts of Albuca setosa bulbs produced the highest lactate with 120.2 μg/ml and 113.7 μg/ml respectively. The acetone extracts of both Albuca setosa and Albuca bracteata revealed toxicity with a higher lactate dehydrogenase release compared to the control.

- Description: This study researched the nature of tasks used in Grade 10 mathematics tests and end-of-year national examinations. The study was carried out in three, purposively selected, Grade 10 schools in the Ohangwena region in Northern Namibia. For the purpose of this study, a mixed method approach was employed to analyse a combination of both quantitative and qualitative data. A sample of three tests per mathematics teacher from the three participating schools and national examinations question papers for the past three consecutive years (2011-2013) were analysed using Stein, Smith, Henningsen, & Silver’s (2000) framework of cognitive demand. The study was divided into two phases. Phase 1 was the analysis of teacher test items and national examination items in terms of their cognitive demand. Phase 2 involved semi-structured interviews with three selected teachers to probe their views and find out their basis for selecting test items. The findings of this study revealed that there was no substantial difference in the distribution of the levels of cognitive demand in both tests and national examinations items. The study, however, showed that mainly tasks requiring only procedures without connections dominated the tests and the examinations. The number of higher level tasks in both tests and examinations analysed was low. There was no single task coded at level 4 in any of the teachers’ tests. Only 2% of tasks could be classified at level 4 in the examination items. The study also revealed that since tests and examinations assess the same learning objectives from the syllabus, most of the test items set by teachers were extracted from the national examinations question papers. The paper recommends that more tasks at a higher level category need to be included in assessment tasks to promote critical thinking amongst learners.

- Description: Scrutiny of the capabilities and accuracy of computer forensic tools is increasing as the number of incidents relying on digital evidence and the weight of that evidence increase. This thesis describes the capabilities of the leading proprietary and open source digital forensic tools. The capabilities of the tools were tested separately on digital media that had been formatted using Windows and Linux. Experiments were carried out with the intention of establishing whether the capabilities of open source computer forensics are similar to those of proprietary computer forensic tools, and whether these tools could complement one another. The tools were tested with regards to their capabilities to make and analyse digital forensic images in a forensically sound manner. The tests were carried out on each media type after deleting data from the media, and then repeated after formatting the media. The results of the experiments performed demonstrate that both proprietary and open source computer forensic tools have superior capabilities in different scenarios, and that the toolsets can be used to validate and complement one another. The implication of these findings is that investigators have an affordable means of validating their findings and are able to more effectively investigate digital media.

- Description: The African continent is endowed with vast natural resources of minerals, such as cobalt, diamonds, gold, bauxite, iron, platinum, silver, uranium and mineral oil. Oil is unequally distributed in the continent, with some countries, such as Cameroon, Chad, Congo Brazzaville, Equatorial Guinea, Gabon and South Africa, being particularly well endowed. These natural resources can help accelerate development on the continent, especially in Gabon and South Africa if used strategically. This dissertation gives an overview of the international instruments, which play a key role in petroleum legislation and development. At the global level, the international legal instruments related to the permanent sovereignty over natural resources (PSNR), such as the 1962 Resolution 1803 (XVII) on Permanent Sovereignty over Natural Resources indicates that States have the rights to exploit freely national resources and wealth, use and dispose their natural resources for the realisation of their economic development in accordance with their national interest. The PSNR must be exercised in line with indigenous peoples’ rights and the respect of rules concerning the expropriation. At the African level, with regard to the right to the State to exploit freely natural resources, the African (Banjul) Charter on Human and Peoples’ Rights of 1981 has similar provisions as the Resolution 1803. The African (Banjul) Charter specifies that no peoples can be deprived of the right to dispose their natural resources. The African Commission on Human and Peoples’ Rights is tasked to interpret the African (Banjul) Charter. The Resolution on Human Rights-Based Approach to Natural Resources and Governance has also indicated principles in relation to the governance of natural resources. At the regional level, the Constitutive Treaty of the Central African Economic and Monetary Community (CAEMC) of 1994 and the Southern African Development Community (SADC) Treaty of 1992 do not provide explicit provisions relative to the PSNR and the management of natural resources. Therefore, it is important to examine if at the national level, the domestic instruments of both States deal with the PSNR.

At the global level, the international legal instruments related to the permanent sovereignty over natural resources (PSNR), such as the 1962 Resolution 1803 (XVII) on Permanent Sovereignty over Natural Resources indicates that States have the rights to exploit freely national resources and wealth, use and dispose their natural resources for the realisation of their economic development in accordance with their national interest. The PSNR must be exercised in line with indigenous peoples’ rights and the respect of rules concerning the expropriation. At the African level, with regard to the right to the State to exploit freely natural resources, the African (Banjul) Charter on Human and Peoples’ Rights of 1981 has similar provisions as the Resolution 1803. The African (Banjul) Charter specifies that no peoples can be deprived of the right to dispose their natural resources. The African Commission on Human and Peoples’ Rights is tasked to interpret the African (Banjul) Charter. The Resolution on Human Rights-Based Approach to Natural Resources and Governance has also indicated principles in relation to the governance of natural resources. At the regional level, the Constitutive Treaty of the Central African Economic and Monetary Community (CAEMC) of 1994 and the Southern African Development Community (SADC) Treaty of 1992 do not provide explicit provisions relative to the PSNR and the management of natural resources. Therefore, it is important to examine if at the national level, the domestic instruments of both States deal with the PSNR.

- Description: Business sustainability is a fundamental concern amongst business leaders and it is imperative that business defines an environmentally and socially sustainable path to financial prosperity. This focus on sustainable business practices has been caused by the perceived contribution of businesses to undesirable conditions such as environmental and social degradation including global warming and the global financial crises. This study suggests that a leadership style that differs from leadership that is currently causing business unsustainability is needed in order to achieve the goal of sustainable business practices. This study therefore proposes a new kind of leadership, called conscious leadership. The main contribution of the study is to increase the achievement of sustainable business practices by investigating the importance of conscious leadership in achieving this objective. Convenience sampling was used to select senior managers and directors from mainly JSE listed companies. This resulted in a total of 371 usable questionnaires (317 from listed companies and 54 from unlisted companies) being received. A quantitative approach was adopted to investigate whether conscious leadership would be related to increased sustainability competencies and more effective sustainability-related corporate governance and whether these in turn would increase sustainability behaviours which would generate sustainable business practices as measured by financial, social and environmental performance. Regression analyses were conducted to investigate the hypothesised relationships among these variables. Pearson correlations and descriptive statistics were also calculated. The empirical results showed that respondents in this study regarded conscious leadership, not as a separate construct, but as a way they governed their businesses. The empirical results showed that corporate governance and systems thinking competency had a strong interactive relationship and should therefore be cultivated within business firms. Corporate governance (including conscious leadership) and systems-thinking competency were positive influencers of employee relations, equal opportunities and workforce diversity. The empirical results however showed that corporate governance (including conscious leadership) had a negative influence on profitability. The present study cannot argue for the discouragement of corporate governance (including conscious leadership), as measured in this study, because reduced corporate governance would decrease healthy employee relations and the latter would decrease the achievement of equal opportunities and workforce diversity in these firms. A decrease in healthy employee relations would decrease profitability. The most important finding of this study is that senior managers and directors of big business firms, mostly JSE-listed companies, regarded conscious leadership as an important part of corporate governance. Corporate governance that includes conscious leadership must be developed to higher levels in business firms, so that the negative and not-significant relationships to profitability as viewed by lower and high conscious leaders respectively can be changed to positive relationships.

- Description: The role of natural resources in African conflicts has been subject to extensive scholarly analysis. However, much of this analysis has taken a narrow economic reductionist bias. As such, it is imperative that the dominant assumptions and accepted concepts and theories about the role of natural resources in African conflicts be re-examined. The aim of this thesis is to offer a revaluation of the role of coltan during the Democratic Republic of Congo’s (DRC) Second War (1998-2003) through a critical engagement with the resource wars literature. The purpose is to offer a re-reading of the role of coltan in the DRC Second War and the broader regional and global economic context in which this conflict took place. It rejects the commonly cited assumption that the presence of coltan in the DRC means it is an initiator of conflict. Rather, this thesis argues that the central role of coltan in the DRC Second War was as an aggravator of conflict in that its exploitation was used by different parties to fund their military and political ambitions. This thesis also argues that the DRC’s weak state structures and pivotal role within the Great Lakes region, as well as the international trade of coltan and the nature of the DRC coltan mining industry are all key factors in understanding coltan exploitation in the country’s Eastern Region during the Second War.

A critical assessment of economic policies and their impact on entrepreneurship development in South Africa: a case of Khayelitsha Township in Cape Town

- Description: The complexity of the South African society due to past systematic exclusion of some communities from economic activities resulted in the triple challenge of poverty, inequality and unemployment. Although various economic policies had been developed since the advent of the democratic dispensation in 1994, these policies focused on levelling the economic environment, poverty alleviation and massive social security system. However, despite all the interventions, South Africa remains one of the most unequal societies in the world. This is profiled by the mushrooming of informal settlements around cities with job seekers and frequent protests by people who are impatient to experience improvement in their quality of life and who feel cheated out of their social contract. Advocacy from the governing party’s tripartite alliance towards a developmental state had placed more obligations on the government. This requires deliberate interventions through policies implementation to improve or at best alleviate the well-being of the citizenry. A survey conducted in the township of Khayelitsha to assess the impact of such economic policies on the development of entrepreneurship. Khayelitsha is one of South Africa’s largest townships, an informal settlement profiled by unemployment, poor infrastructure and unavailability of basic services. The study explored the entrepreneurial perception, start-up barriers, entrepreneurship climate, and general cultural factors relating to the environment of entrepreneurship development. The results reveal that despite the various economic policies, high level of unwillingness of citizens towards entrepreneurial activity and business venture is rife notwithstanding the high level of unemployment and poverty. The antidote to these challenges would be a rapid entrepreneurship drive among people most affected that would cause them to mind their own business” and become “masters of their own destinies. Given the complexity and massiveness of the challenges, the conclusion shows that a pragmatic solution is required. Therefore, the emancipation of entrepreneurship development in South Africa townships needs attention. The recommended solution is a pragmatic and innovative strategy based on the acronyms NEEDS HELP which stand for Neighbourhood Enhancement and Environmental Development Strategy and Holistic Entrepreneurial Lifestyle Programme. , Thesis (PhD) -- Faculty of Management and Commerce, 2015

- Description: The research problem was based on the private sector implementation of Responsible Tourism, since 1996, perceived to be slow and challenging (Frey & George, 2010: 107). The South Africa Government proposed Responsible Tourism as the guiding principle for sustainable tourism development (Goodwin, 2011: 138). The problem is compounded by shortcomings identified in the nature of the research conducted about tourism and communities and the methodologies used. Tourism-Community relationships Theory was applied as the conceptual framework of the study. This theory advocates a holistic approach when conducting research about the impacts of tourism, encompassing community perspectives, attitudes, reactions and considerations for the future development and control of tourism (Pearce, Moscardo & Ross, 1996: 2). The insights gained contributed an emic understanding of the keyinformants’ perspectives imparted in their own language. This study is located in the Interpretevist paradigm, underpinned by Constructivist philosophy. Meaning is created through the reality of key-informants, their perspectives and the interaction of individuals in a community (Cresswell, 2014: 8). The Instrumental Case Study Approach (Stake, 1995) contributed an etic perspective in terms of the researcher’s interpretations. The single, qualitative case was applied to gain deeper insights about the phenomenon of Responsible tourism. The case investigated was Stormsriver Adventures (SRA), an eco-adventure tourism business in the Tsitsikamma tourism destination in the Eastern Cape region of South Africa. SRA is reputed to be business best practice in its implementation of Responsible Tourism. Data triangulation was established through multiple methods of data collection, namely in-depth interviews with key-informants, documentation sourced from them and researcher observation. Data analysis methods, namely direct interpretation, categorical aggregation, pattern seeking and naturalistic generalisations (Stake, 1995), were used. The member checking process assisted with establishing data triangulation as keyinformants corroborated or dispelled the researcher’s interpretation of data. Findings were structured according to within-case themes, namely SRA’s perspective of its Responsible Tourism practices, the community’s perspective of SRA’s Responsible Tourism practices and perspectives about the future development and control of tourism. The study contributes new theoretical insights through applying the inductive approach to selected findings. Findings indicate that the perspectives of the community are divided. SRA keyinformants conveyed positive economic, social and environmental impacts of SRA’s Responsible Tourism practices. Key-informants not directly linked to SRA raised negative economic impacts and questioned the accuracy of SRA’s marketing messages. Within-case conclusions are that it is not the responsibility of one tourism business that practices Responsible Tourism to achieve sustainability within the tourism destination. To this end it is recommended that SRA and the community find common ground and that the misunderstandings that exist, be addressed. The study concludes that in order to achieve successful Responsible Tourism- Community Relationships, a holistically and integrated approach is required. To this end the recommendations made provide an implementation framework within the context of a tourism destination. The study adds value to the field knowledge about the implementation of Responsible Tourism by the private sector in South Africa and also contributes new knowledge to the field of tourism in terms of the particular methodology used.

- Description: South African history is rooted in racial identities, inequalities and injustices, which the post-apartheid government has sought to address for twenty years since 1994. The transition to a post-apartheid society though has been a difficult one with the social structure and everyday life still marked by the racial past. Though racial classifications on an official basis no longer exist, racial identities continue to pervade the country. Of particular significance to this thesis are black identities including the possibility of black inferiority, which I examine in relation to black post-graduate university students in contemporary South Africa, specifically at Rhodes University. In examining this topic, I draw extensively on the work of Frantz Fanon, who wrote about both colonial society and the emerging post-colonial experience. Fanon was a young black intellectual whose work was in part based on his own experiences of being a once-colonised black person in a world which he perceived as being dominated by whiteness. In his work he expresses his own perceptions of whiteness and how the black identity has come to be shaped by and around this dominant white foundation. Fanon extensively discussed the lives of black intellectuals and elites, and demonstrated how the black identity becomes shaped by and around the world of whiteness. In doing so, he raised a range of themes, such as black inferiority, mimicry and double consciousness. I draw upon the work of Fanon in a critically sympathetic manner to delve into the experiences of black postgraduate students as they negotiate their way through a university setting dominated by a white institutional culture. I bring to the fore the argument that the racial identities of these students is not fixed and sutured but, rather, is marked by considerable fluidity and ambiguity such that black identity must be understood not just as a state of being but also as a process of becoming.

After sexual maturity, oogenesis and spermatogenesis continued throughout the year and were found to be similar to these processes in other seabream species and teleosts in general. Analysis of maturity data over the past two decades revealed a significant change in both age and size-at-maturity, a response to fishing pressure.

- Description: Face-to-face adult communication with young people about sexuality is, for the most part, assigned to two main groups of people: educators tasked with teaching schoolbased sexuality education that is provided as part of the compulsory Life Orientation (LO) learning area, and parents. In this paper, we report on a study conducted with Further Education and Training College students in an Eastern Cape town. Using a discursive psychology lens, we analysed data from, first, a written question on what participants remember being taught about sexuality in LO classes and, second, focus group discussions held with mixed and same-sex groups. Discussions were structured around the sexualities of high school learners and the LO sexuality education that participants received at high school. We highlight participants’ common deployment of a ‘discourse of disconnect’ in their talk. In this discourse, the messages of ‘risk’ and ‘responsibility’ contained in adult face-to-face communications, by both parents and LO teachers, are depicted as being delivered through inadequate or nonrelational styles of communication, and as largely irrelevant to participants’ lives. Neither of these sources of communication was seen as understanding the realities of youth sexualities or as creating habitable or performable sexual subject positions. The dominance of this ‘discourse of disconnect’ has implications for how sexuality education and parent communication interventions are conducted.

- Description: This thesis analyses the influence of monetary policy on the general price level in Zimbabwe during periods of hyperinflation and dollarisation. The first part of the analysis covers the period January 2006 to July 2008 when the country experienced high inflation and ultimately hyperinflation. The second part covers the period 2009 to 2012, when the country adopted the multi-currency system and became fully dollarised. In terms of motivation, the study firstly sought to empirically examine the factors that led to hyperinflation in Zimbabwe, paying particular attention to the influence of monetary policy. Secondly, the thesis sought to determine the major factors that influenced price formation in a dollarised Zimbabwean economy; a completely new macro-economic environment. A significant development in this new macro-economic environment was the loss of monetary policy autonomy of the central bank, which also contributed to the relevance of the study. This thesis makes two contributions. The first contribution is the finding that hyperinflation in Zimbabwe was caused by expansionary monetary policy as a result of the activities of an unrestrained and unaccountable central bank. The second contribution was the empirical finding that in the fully dollarised economy inflation is largely determined by external factors. This implies that the domestic economy has no control over domestic inflation developments and as such, Zimbabwean authorities should formulate appropriate economic policies to respond to the impact of external shocks on domestic price formation when the need arises. The role of monetary policy in Zimbabwe’s hyperinflation episode is assessed using the Autoregressive Distributed Lag (ARDL) and the Error Correction Model (ECM) approaches with monthly data from January 2006 to July 2008. The impact of monetary policy on hyperinflation is captured by the coefficient of broad money supply and the interest rate. Results indicate that hyperinflation was caused by expansionary monetary policy, the exchange rate premium and inflation expectations for both the short and long term. Zimbabwe’s hyperinflation episode which peaked during the period 2007 to 2008 brings to the fore the importance of ensuring that the central bank is independent in executing its mandate of influencing the monetary policy process in a manner that ensures price stability. The ARDL and ECM approaches are also used to explore the dynamics of inflation in the dollarised Zimbabwean economy, with monthly data from January 2009 to December 2012. The main drivers of inflation under the multi-currency system were found to be the United States of America dollar/South African rand exchange rate, international oil prices, inflation expectations and the South African inflation rate. The findings contrast with the hyperinflationary era, where empirical studies have cited excessive money supply growth as the major driver of inflation dynamics in Zimbabwe. The results also suggest a higher exchange rate pass-through to domestic prices, consistent with empirical literature which postulates that inflation in dollarised economies is largely explained by movements in the exchange rate of major trading partners and international prices. The policy implication from the analysis is the need for policy makers to aggressively promote policies that ensure increased productivity of the economy. An improvement in productivity would influence the relative prices of tradable and non-tradable goods and ultimately the general price level in the economy. The study also quantified the independence of the Reserve Bank of Zimbabwe (RBZ) using the Mathew (2006), “new index for institutional quality” and the results showed that the RBZ is not an independent central bank. The central bank is found to have a low index of central bank independence (CBI), against a high level of inflation. While this relationship does not imply causality it can be inferred that the lack of independence of the RBZ could have influenced inflation dynamics in Zimbabwe. Only a subordinated central bank can be compelled to engage in inflationary deficit financing and also fund quasi-fiscal activities. The provisions of the RBZ Act [Chapter 22:15] in their current form make the central bank an appendage of the Ministry of Finance and Economic Development and this has, to a large extent, resulted in conflict between the political goals of government and the central bank’s primary objective of achieving price stability. In the event that Zimbabwe reintroduces its own currency in future, the achievement of the primary goal of price stability by the central bank will only be realised if the apex bank is given more autonomy.

A flight of fancy in the Chorister Robin-Chat (Cossypha dichroa) : an isotopic standpoint

- Description: Forested areas have been cited for their highly diverse floral and faunal assemblages, which are currently under threat from anthropogenic activities that restrict their range and deplete the resources produced within these naturally fragmented patches. Historically, up to 67 percent of avifaunal species associated with well-treed areas have undergone localised extinctions, consequentially affecting biodiversity as a measure of species richness and ecosystem functionality. To date, more than 900 of the bird species affiliated with forests are under threat and despite the theory surrounding functional redundancy, the mass extinction that is currently underway poses considerable limitations on the ecological integrity of these biomes. In South Africa, indigenous forest (one of the rarest biomes), occurs predominantly in small isolated patches along the eastern escarpment. With mountainous terrain emphasised as ‘prominent hotspots of extinction’, the limited dispersal and habitat sensitivity of montane forest fauna renders these species more prone to localised extinctions. BirdLife International, the IUCN and SABAP2 all indicate reductions in the range and abundance of the Chorister Robin-Chat (Cossypha dichroa) - an endemic forest specialist that is reported to move seasonally between high-altitude forest patches where they breed in summer, and lowland coastal forests where they overwinter. Beyond diet, body morphology and vocalisations, much of the information available on the altitudinal movements of C. dichroa is based on secondary sources and the assumptions therein. This study aimed to investigate the potential utilisation of δ13C and δ15N stable isotopes in determining the dietary niche width and altitudinal movements of C. dichroa. Feathers obtained in forested patches of the Limpopo, KwaZulu-Natal and Eastern Cape provinces exhibited a wide trophic niche width and generalised diet. Strong regional separation is apparent in the isotopic signatures suggesting little movement between provinces. A comparison of 13C-isotopes showed minimal variation that point to a uniformity in the carbon-base utilised by C. dichroa across their range. The 15N-signatures obtained in Limpopo, however, revealed a distinct trophic segregation between the northern-most Chorister populations and their southern counterparts. No altitudinal movements were detected in the isotopic signatures of recaptured Choristers, but more research is needed to investigate the long-term accuracy of these results and the breeding potential of resident Choristers in lowland coastal forests; especially when considering the reduced range and abundance reported for this endemic species.

- Description: The changing business environment has increasingly driven organisations to incorporate sustainability into their corporate strategy for them to remain competitive. The economic, social and environmental goals and objectives of the organisation are now being factored into corporate strategy. This is as a result of the opportunities presented with the adoption of sustainability as a strategy and the threats caused by failure to adopt sustainability within their corporate strategy. For organisations to reap any benefits of incorporating sustainability, successful implementation of the strategy is needed. The role employees’ play in the implementation process of the sustainability strategy is critical. For successful implementation of the strategy, employee commitment is required as they have to adjust their actions and behaviours to be congruent with those required for the successful implementation of the sustainability strategy. However literature suggests that employees have received little attention in past research in regard to sustainability especially in emerging markets where research on sustainability has been limited. For this reason, the research problem for this study was how employee commitment can be improved towards the implementation of the sustainability strategy in their day-to-day operations. To achieve this objective, a conceptual framework was developed by investigating the organisational factors that impact on employee commitment to implementing sustainability in their day-to-day activities. To develop the conceptual framework, a literature review was conducted. The conceptual framework served as a basis for the construction of the questionnaire, to determine the nature of employee commitment to sustainability, to what extent they were implementing sustainability in their day-to-day activities and finally for the employees who were committed and were implementing sustainability what were the organisational factors that influenced their commitment to the sustainability strategy. The questionnaire was distributed to employees of different organisations in the Nelson Mandela Bay Metropolitan area who were MBA students at Nelson Mandela Metropolitan University. The findings of the empirical study indicate that the majority (75.5%) of the respondents were committed to all the tenets of sustainability, and were implementing the sustainability strategy. Though there were trade-offs in how the sustainability strategy was implemented, with the economic aspect having precedence where 84.5% of the respondents were implementing it, 70% of the respondents were implementing the social aspect of sustainability and 72.2% implementing the environmental tenet of sustainability. The organisational factors that influenced employee commitment to sustainability as was developed in the conceptual framework were all positively confirmed by the findings of the empirical study. Employee socialisation had the highest influence on commitment, followed by leadership, culture, communication, sustainability programmes and finally performance management. Formal and informal socialisation in the form of training and influence from experienced employees was the leading organisational factor that influenced commitment. The different roles top and middle management played in regard to sustainability followed. The organisational culture that existed in the organisation and the internal communication that was received all contributed to employee commitment to sustainability. The sustainability programmes in place and performance management systems in place were all organisational factors contributing to employee commitment to sustainability.

- Description: Cloud computing adoption and usage is important to achieving business competition. This is done by making it a competitive tool for firms. The adoption of cloud computing enables firms to achieve greater business competency, improve performance, and allows them to maintain their competitive advantage. Since its emergence, there has been a surge in the adoption of cloud computing with research into its adoption primarily concentrated on bigger firms. However, a major characteristic of cloud computing is the anticipated possibilities it holds for small and medium-sized enterprises (SMEs). SMEs typically operate differently from larger firms and are not limited by resource constraints. For SMEs, the reduction in the financial burden normally associated with the adoption of new technologies is a significant benefit of cloud computing due to their financial constraints. In Ghana, SMEs mostly use obsolete technologies and have a slow response towards new technologies. Thus, they are unable to harness the numerous opportunities technology presents to them to stay competitive. Cloud computing is still regarded as a new technology in the business world, therefore research that focuses on its adoption by SMEs to help them stay competitive is minimal. Available research on cloud computing in Ghana does not provide clear guidelines for ensuring a successful adoption process and the continued use of cloud computing services. This study seeks to investigate how a framework can assist SMEs in their use of cloud computing in the Accra-Tema metropolis of Ghana. A knowledge of the factors associated with adoption decisions and those that significantly influence the decision are required to ensure a successful adoption process. The empirical data was gathered using a questionnaire and face-to-face interviews developed from literature and administered to users and potential users of cloud computing. The questionnaire and interviews primarily investigate key adoption factors and the findings are reported in this research study. The findings reveal interesting insights into understanding issues that affect the overall decision to adopt and use cloud computing services by SMEs. The findings show that the adoption of cloud computing can improve information management practices within SMEs. The findings also reveal that several factors need to be considered in the overall decision to adopt and use cloud computing to ensure a successful adoption process. An initial cloud computing adoption model was proposed based on the empirical findings. Key adoption factors of the initial adoption model include adoption benefits and drivers, concerns and barriers, adoption interventions, and information management in the cloud. computing adoption framework. The proposed adoption framework aims to assist SMEs to adopt and use cloud computing services and make them relevant in the global market.
