- Description: Individuals are often not aware of the required level of contributions needed to fund a retirement savings plan. This problem is compounded by the fact that the assistance provided to these individuals by way of commercially-available retirement planning models does not take into account the effect of income tax on the level of required retirement savings contributions and recent changes in the tax legislation to the income tax payable by individuals has had a significant effect on these required levels. As a preamble to the research process, an exploratory questionnaire was administrated to a sample of individuals, which was designed to measure the level of awareness of these individuals of the contributions to a retirement savings plan needed to fund their postretirement financial needs, and of the impact of age, the level of income and income tax on their contributions. Responses to the questionnaire indicated a low level of awareness of retirement planning amongst these individuals. A retirement planning model was then designed to test the effect of earnings, age and changes in tax legislation on the level of an individual's required monthly contributions to a retirement savings plan. Independent variables of age and income were processed using the model. These same variables were then processed using the Old Mutual and Liberty Life retirement planning models and a comparison was made between the model developed in the research and these commercially developed models, to assess their usefulness and limitations. Based on the above comparison, it appeared that the Old Mutual and Liberty Life retirement models both included the effects of the individual marginal tax rates in their calculations. However, they appeared to be using marginal tax rates which were higher than those reflected in the 2006 individual income tax tables. In addition these models did not include the effect of income tax exemptions and deductions and they therefore provided more conservative estimates than the retirement planning model designed in the research. Recent tax adjustments have had the effect of greatly increasing the after-tax income of individuals and therefore it is important to include the effects of changes in tax legislation in determining the monthly contributions to a retirement savings plan.

- Description: Mining companies operating in developing countries like the Democratic Republic of Congo (DRC) have come under increasing public criticism for not only failing to bring benefits to the country in which they operate but for often making the situation even worse through adverse environmental and social impacts. The particular focus of this treatise is the social division that a new mining project can generate between the operating company and the community living on or near to the mine site. In one area in north-eastern DRC, a large multinational mining company, AngloGold Ashanti, plans to develop a gold mine. While there have been no manifest conflicts between the company and the host community, there is evident latent conflict in the form of uncertainty and mistrust between parties. Although the company is engaged in two different models of companycommunity participation, this has either resulted in or failed to prevent tensions between the company and the local community. This research offers an exploration and discussion of the existing models of company-community participation as a conflict management strategy. With reference to relevant research and literature, as well as other available models for company-community participation, this treatise will provide a series of recommendations as to how the existing models could be made more effective in managing conflict.

- Description: Globalisation and financial liberalisation has increased the linkages across countries in recent times. The existence of money market links has important implications for both domestic monetary policy and for investment decisions. This study examines the linkages between South Africa’s money market and selected major international money markets. The objectives of the study are firstly to examine the links between the repo rate of South Africa and the central bank rates of the EU, Japan, UK and US. Secondly, is to compare the influence of domestic and foreign monetary policy decisions on South Africa’s money market. The third objective is to examine the long run relationship between the South African money market and the money markets of its major trading partners. Three estimation techniques are used to examine the different links. Principal components analysis, four tests of cointegration, and stationarity tests of the spreads/risk premium between South Africa’s interest rates and the interest rates of the other countries. All three techniques show that there is no long-run link between South Africa’s central bank rates and the central bank rates of the other countries. This shows that the repo rate does not depend on movements in other central bank rates. Domestic money market interest rates respond strongly to changes in the repo rate whilst showing no dependence on central bank rates of the other countries. This confirms the autonomy of the South African Reserve Bank in carrying out policy objectives. When the risk premium is accounted for under the third technique, evidence of integration is found. This indicates that the risk premium plays a crucial part in the level of integration between South Africa and the countries included in the study.

- Description: Most orogenic type gold deposits are formed under low greenschist facies to mid amphibolite facies metamorphic conditions and deposition is either structurally or lithologically controlled. A few known gold deposits found in high grade metamorphic terranes include those in the Yilgarn craton in Australia, Renco in Zimbabwe, Hemlo in Canada and the recently discovered Handeni deposit in Tanzania. Within Tanzania, gold deposits are mainly hosted in Archaean low grade metamorphic rocks commonly known as the Lake Victoria greenstone belt. The greenstone belts of Tanzania are of Nyanzian age (> 2.5Ga) and are located to the south and east of Lake Victoria on the Tanzania craton. The Tanzania Craton is surrounded by Usagaran 1.9 Ga rocks (the east African orogenic belt (EAO) better known as the Mozambique belt) to the east and the Ubendian belt to the south and west. Published reports show that the eastern part of the Tanzania Craton is dominated by the fragments of Archaean rocks. Metamorphism along East Africa and the Tanzania Craton is due to several geological events. These geological events include the intrusion of granites in the Archaean Tanzania Craton (3 Ga), subduction of ocean plate resulted to the formation of Usagaran belt (1.9 Ga), opening and closure of Mozambique Ocean, which resulted in the formation of the Mozambique belt between 700 – 800 Ma and the Pan African orogeny at 640 – 620 Ma, which is associated with the formation of Gondwana. It is believed that fragments from the Archaean Tanzania craton were re - metamorphosed during these events. The Handeni project (the focus of this thesis) is located in the northern portion of the eastern part of the Usagaran belt (1.9 Ga) comprising the eastern part of Archaean Tanzania Craton. The area is characterized by Proterozic rocks of basaltic composition. The documented 2.7 Ga rocks at the Kilindi Handeni Superterrane at the northern part of the Usagaran belt correlate well with 2.7 Ga of Nyanzian rocks of Archaean Tanzania craton. The Handeni project area is geologically dominated by metamorphosed and deformed units of quartzofeldspathic gneisses, migmatitic gneiss, garnet silicified rock, garnetiferous amphibolite, garnetiferous granulite, graphitic schist and hornblende pyroxenite. Intensive deformation features that were developed include folds (sheath folds, micro and macro scales), faults, shears and regional thrusts. This thesis focuses on identifying the protolith of the rocks, alteration minerals, and metamorphic assemblages in the project area in order to understand the timing of gold mineralization. Geological investigation of core, ore petrology and mineralogy, mineral composition by using JEOL microprobe analysis and XRF analysis of bulk rocks were utilized. All the analytical work was done at the Geology laboratory, Rhodes University. Petrographic analysis shows that the rocks sampled in the study area are characterized by alteration minerals such as calcite, dolomite and sericite. Sulphide minerals including chalcopyrite, pyrrhotite, pyrite, pentlandite and gersdorffite were identified. Gold mineralization is associated with disseminated sulphides in association with trace amounts of base metals. Four rock types were proposed as host rocks for the mineralization, namely garnet silicified rock with superimposed quartz veins, garnetiferous amphibolite, garnetiferous granulite and hornblende pyroxenite. Fold troughs, filled fractures associated with episodes of folding, quartz veins and shear zones are suggested as gold precipitation sites. The presence of high grade metamorphic rocks containing gold, intermediate to low grade assemblages with sulphides and associated hydrothermal alteration as well as a complex deformation history suggests that the Handeni mineralization took place over an extended time period stretching from a ductile to a brittle environment.

- Description: The aim of this research is to evaluate the level of service quality provided by Eskom to its Large Power User (LPU) customer segment in the Eastern Cape. The research uses the SERVQUAL model in order to assess the customers’ expectations and perceptions of the service provided by Eskom. This evaluation report comprises three sections. Section one consists of (a) a review of service quality literature that exists and is applied to Eskom where relevant, (b) a summary of the method used to conduct the research, (c) the research findings, and (d) a discussion of the research findings and recommendations. Section two consists of a review of the key concepts identified for this study as follows: (a) defining customer service quality by looking at the concepts of the customer, service, quality and the dimensions of quality, (b) the importance of service quality, (c) the components of service quality in Eskom, (d) models of service quality, and (e) the SERVQUAL model used in this study. Section three consists of the detail of the research methodology used to conduct this study. The Gap Model of Service Quality (Parasuraman et al., 1985:44) is evaluated in order to understand the gaps between expected and perceived service. The provider gap (Zeithaml et al., 2006: 34) is also reviewed in order to identify the gaps that occur within the organisation. An extensive review of customer service quality models is undertaken before a discussion of the SERVQUAL model, which was used in this evaluation study, is provided. The researcher adopted the critical realism research paradigm and quantitative data was collected from a sample of 120 Eskom customers within the LPU customer segment in the Eastern Cape. These customers were randomly selected from the Eskom Customer Care and Billing database and comprised customers from Port Elizabeth, Aliwal North, Mthatha and East London Areas within the Eastern Cape. The data was collected online through a questionnaire which was based on SERVQUAL and modified for electricity services. The quantitative data obtained from the study is presented in the form of tables and graphs created from the data obtained from the 45 customers who responded to the questionnaire. The gaps between LPU customer perceptions and expectations were calculated for the five SERVQUAL dimensions. The research identifies the existing gaps in the service delivered by Eskom; this is based on the perceptions and expectations of the LPU customers in the Eastern Cape, who participated in the study. The results reveal that gaps exist between LPU customer perceptions and their expectations of the service provided by Eskom in the Eastern Cape. The key findings reveal that the largest gaps are within the reliability and empathy dimensions and the smallest gap is in the tangibles dimension. The recommendations were made on the basis of the gaps which were identified and these focus on the training of the front line staff responsible for servicing customers. It is recommended that this training should include an overview of the organisation’s policies and procedures to enable employees to respond adequately to customer queries. Recommendation is also made on training staff to interact with customers effectively in order to resolve customer queries satisfactorily. Finally, it is recommended that regular assessments of the existing customer service quality levels are conducted in order for the organisation to remain aware of the current customer perceptions and expectations

- Description: The international linkages of stock markets have important implications for cost of capital and portfolio diversification. Recent trends in globalization, financial liberalization and financial innovation raises questions with regard to whether African stock markets are being integrated into world equity markets. This study examines the extent to which the South African (SA) equity market is integrated into the world equity markets using daily data for the period 1995-2007. The study is divided into three main parts, each looking at the different ways in which integration can be considered. The first investigates whether there is long run comovement between the SA and the major global equity markets. Both bivariate and multivariate Johansen (1988) and Johansen and Juselius (1990) cointegration approaches were utilised. Vector Error Correction Models (VECMs) are then estimated for portfolios which show evidence of cointegration. The second part analyses returns linkages using the Vector Autoregressive (VAR), block exogeneity, impulse response and variance decomposition. The third part examines the behaviour of volatility and volatility linkages among the stock markets. Firstly volatility is analysed using the GARCH, EGARCH and GJR GARCH. Simultaneously, the hypothesis that investors receive a premium for investing in more risky stock markets is explored using the GARCH-in mean. The long term trend of volatility is also examined. Volatility linkages are then analysed using the VAR, block exogeneity, impulse response and variance decomposition. The first part established that no bivariate cointegration exists between the SA and any of the stock markets being studied, implying that pairwise portfolio diversification is potentially worthwhile for SA portfolio managers. However, multivariate cointegration exists for some portfolios, with the US, UK, Germany and SA showing evidence of error correction for some of these portfolios. Findings on return linkages is that there are significant returns linkages among the markets, with the US and SA being the most exogenous and most endogenous respectively. Findings regarding volatility are that the volatility in all the markets is inherently asymmetric and that except for the US there is no risk premium in any of the markets. The long term trend of volatility in all the stock markets was found to be relatively stable. The final finding was that significant volatility linkages exist among the markets, with the US being the most exogenous and SA and China showing evidence of bidirectional linkages. Overall, except for volatility linkages, the integration of SA into the global equity markets is still quite low. Thus, both SA and international investors can capitalise on this portfolio diversification potential. On the other hand, policy makers should capitalise on this and make policies that will attract the much needed foreign investors.

- Description: The aim of the study was to obtain preliminary normative data for two tests of hand motor function (Successive Finger Tapping and Purdue Pegboard tests) and two tests of verbal fluency ("S"-Words-In-One-Minute and Words-In-One-Minute), administered in English, on a non-clinical sample of black, isiXhosa-speaking unskilled workers with a background of relatively disadvantaged former DET education (N = 33). The sample was equally distributed for gender; educational level was restricted to 11 - 12 years; age range was 18 - 40 years divided further into two age categories (18 - 29 and 30 - 40 years). Results of t-test comparative analyses revealed significant age effects on both trials of the Successive Finger Tapping test in the direction of the younger age group outperforming the older age group, and a marginal but consistent tendency towards poorer performance at an earlier age stage than proposed by the available literature, for the Purdue Pegboard, "S"Words- In-One-Minute and Words-In-One-Minute. Gender effects were only in evidence on the Purdue Pegboard in the direction of females outperforming males. A descriptive comparison of the norms acquired for the present study with available normative data for English first language speaking populations with higher levels and/ or relatively advantaged quality of education revealed consistently poorer performance for the present study. The findings highlight the effect of relatively low levels and/ or poor quality of education on both verbal and non-verbal neuropsychological test performance and confirm the need for demographically specific normative data.

- Description: This dissertation seeks to articulate a liberatory conception of philosophy which interprets reality on its own terms. It is an attempt to intervene in the practice of philosophy in South Africa, which has continued along colonial lines expressed through the marginality of African philosophy up to the present, to the general neglect of the unjust and divisive social reality that defines South Africa. It is our argument that such a continuity is indicative of outstanding liberation on the part of the indigenous people conquered in the unjust wars of colonisation. Our main task then is to struggle for this liberation at the epistemic level with Archie Mafeje, through an examination of his intellectual works and life as a revolutionary intellectual, as an inspiration and an instance of a liberatory practice of philosophy. We draw on the work of Archie Mafeje to elaborate and defend his account of African Philosophy, as a historically specific expression of the liberatory struggle of Africans against unjust Euro-centric colonial domination. This shall be achieved in three instances. In the first instance, Chapter 1, we trace the history of institutionalised philosophy in South Africa outlining Eurocentrism and mimesis as its defining features. In the second instance, Chapter 2, a history of contemporary African philosophy is outlined as emanative from the question concerning the existence of African philosophy, of which mainstream South African philosophy has largely been ignorant. In the final instance, Chapter 3 and 4, a liberatory practice of philosophy is presented, as a necessary response to this context, with Mafeje’s account of African philosophy defended as such an instance. The birth of the Azanian Philosophical Society is also presented as such an instance and as a challenge to the unchallenged hegemony of white philosophy in South Africa.

- Description: Internationally, in both developed and developing countries, it has been accepted that SMMEs are the backbone and the driving force of economic growth and job creation. In South Africa, SMMEs account for approximately 60 per cent of all employment in the economy and more than 35 per cent of South Africa's Gross Domestic Product (GDP) (Ntsika, 1999:38; Gumede, 2000:67 and Berry et ai, 2002 in Kongolo, 2010:235). SMMEs are often the vehicle by which the lowest income people in our society gain access to economic opportunities. The sector represents 97.5 per cent of the total number of business firms in South Africa and that it contributes 42 per cent of total remuneration. SMMEs account for some 3.5 million jobs and have between 500 000 and 700 000 businesses (Abor and Quartey, 2010:2337). Due to the above-mentioned contribution, the South African government initiated a number of SMME support programmes aimed at promoting, growing and developing the SMME sector. As a result, a number of national government agencies such as the National Youth Development Agency (NYDA), Khula Finance Limited, the National Development Agency (NDA), the Small Enterprise Development Agency (SEDA) and many other national , provincial and local government organizations were established post 1994. However, despite the concerted efforts by government to develop the sector, SMMEs are, after 17 years of democracy, still faced with enormous challenges such as access to markets, information, appropriate technology, finance, to mention but a few. Of the above-mentioned challenges, access to finance is on top of the list of these. This study, therefore, is aimed at investigating external, institutional and internal constraints impacting on SMME access to finance in the Buffalo City Metropolitan Municipal area. The study is also aimed at ascertaining which of the abovementioned constraints have the greatest influence to SMME access to finance. In developing the framework of the study, recent empirical research conducted around the country and internationally on constraints influencing SMME access to finance (Bbenkele, 2007:18; Ganbold, 2008:45; Mahadea and Pillay, 2008:99; Chenesai, 2009:135; Zindiye, 2009:78; Fatoki and Garwe, 2010:2765; Pandula, 2011 :257) was drawn upon. In order to meet the objectives of the study, a simple random sample survey of 50 SMMEs in the Buffalo City Metropolitan Municipality (BCMM) jurisdiction was conducted. The profile of the SMMEs was very similar to that of other studies that focused on constraints to SMME access to finance. A structured questionnaire was used to collect data from SMME owner-managers and a response rate of 60 percent was achieved . The results of the study indicated that the high cost of credit and interest rates and Value Added Tax (VAT) registration were the key external factors that impacted on SMME access to finance. Generally, SMMEs are viewed by lending institutions as high risk category. Therefore, even though interest rates have come down significantly, the cost of credit and interest rates still remain a constraint. The study also found that even though the South African Revenue Services (SARS) has increased the VAT threshold to R1 million (South African Revenue Service, 2007: 29), SMMEs still struggled to register for VAT. With regards to the institutional factors, the study revealed that ineffective support services provided by private and public SMME support agencies, the lack of communication of these services (access to information) and the lack of the subsequent follow-up services were the key constraints to SMME access to finance. The results of the study indicate that those firms with good track record, high annual turnover, sophistication and diverse skills, good credit record, good cash flow, proper financial records, bankable and viable business plans, collateral and registered for VAT were more likely to have access to finance than their counterparts. The main conclusion of the study is that the internal factors turned to have the greatest influence to SMME access to finance. However, there is more to be done by private and public SMME support agencies and lending institutions to address the above-mentioned institutional constraints which have a negative influence to SMME access to finance. It is recommended that more in-depth empirical research be conducted on the support services provided by private and public SMME support agencies in terms of the services that they offer the effectiveness of the services and how these are communicated to potential customers. It is also recommended that training workshops aimed at addressing the intemal constraints identified be conducted. Also recommended is the development and implementation of sector-specific mentoring programmes for the owner-managers. Strategies to improve the awareness of support services provided by SMME support agencies need to be developed. This would ensure the effective use of these services by SMMEs. It is also recommended that SMME support agencies and lending institutions staff be trained in order to better understand and be more responsive to the owner managers' needs. Linkages with tertiary institutions in planning and conducting the training needs to be made.

- Description: The study evaluated the use of saliva as a minimally invasive technique for cortisol level determination. This was done by assessing the relationship between serum and saliva cortisol based on short sampling intervals. In addition, the study also determined the effect of successive handling on faecal glucocorticoid metabolites (FGM), rectal temperature (RT), avoidance distance (AD), chute and crush scores as well as urination, defaecation and vocalization in multiparous cows. For trial one six non-pregnant, clinically healthy Nguni cows were used. They were administered with standardised doses of adrenocorticotropic hormone on treatment days and saline was used as a placebo on alternative days. Simultaneously, blood and saliva samples were collected to quantify cortisol levels. No relationship (r = 0.0131, P>0.05) was observed between serum and saliva cortisol. However, results showed that there was adrenal stimulation in saliva coupled by significant (P<0.05) effects of sampling intervals. For the second study 21 non-pregnant and clinically healthy Nguni cows of one herd were used for the trial. They were divided into parity groups and their weights were used as a covariate in data analysis. For five consecutive weeks, fresh faecal samples were extracted and rectal temperatures measured. In addition, fear of approaching humans was assessed by AD scores and behaviour scores in the crush chute, as well as vocalisation, urination and defaecation were observed. The effect of successive handling significantly (P<0.05) affected the physiological parameters, namely FGM and RT. Contrariwise, Chi-square tests revealed that parities had a significant (χ2 < 0.05) influence on AD and crush scores as well as on the occurrence of excretory behaviour. It was concluded that saliva cortisol can be used as a stress indicator in beef cows. However, plasma cortisol can be significantly volatile thereby becoming less sensitive to changes across time. This can cause a lack of relationship between plasma and saliva cortisol. On the other hand, repetitive handling of beef cows has an influence on faecal stress levels. In addition, beef cows of differing parities behave differently to handling stress.

- Description: The study investigates the role of media in promoting free debate in Lesotho: A case study of democratic debate on People’s Choice (PC) FM “Thahameso” and Harvest FM “Tsa Mabatooa in Lesotho. Firstly, the study looked at the democratic communication in the volatile democracy of Lesotho, by providing historical factors of pre-independence and authoritarian governments, democrocatic governments prevailing and the dependence on South Africa. Secondly, the study provided literature on the role of broadcast media in different forms of government globally. Thirdly, it provides the analysis and transcription of one month’s recordings of the two political talk shows in Sesotho and identifies the communicative strategies used in this live on-air political discussion by talk show hosts, guests and callers. In these talk shows the researcher identifies the caller, host and guest behaviour and attitudes in discussions that relate the current political situation to the historical development of democracy in Lesotho alongside the economic and political influences from South Africa. The researcher also identifies that the talk show, guests and callers in the challenging political climate use traditional figurative expressions and biblical quotations to express their views. This leads the researcher to conclude that the political talk shows indeed facilitate participatory communication.

- Description: The research problem addressed in this study was to identify guidelines to improve business processes that will enhance the ability of Small, Medium, and Micro Enterprises (SMME’s) to be able to operate competitively in local and global markets. Reengineering of business processes (BPR) is necessary because of internal factors such as increasing global competition, increasing domestic competition, new technologies, industry overcapacity, shrinking markets and increasing pressure from suppliers. There are also various external factors that influence the necessity to reengineer business processes. These factors include increasing cost structure, declining profitability, declining sales, low productivity, inadequate employee skills and less efficiency in operations. In order to identify guidelines that will enhance SMME’s performance, questionnaires with relevant questions were used . The findings of the literature survey clearly highlights the specific areas where attention is required for improvements.

- Description: Community-based organizations (CBOs) play a crucial role in sustainable development and hence it is important that they are promoted, guided and supported by state agencies and the private sector. The South African government encourages communities to establish co-operatives as a tool or strategy to address local social issues and risks and act accordingly. The purpose of this case study was to determine what aspects of the establishment and operation of a successful community-based environmental organization are producing sustained school and community projects. The study set out to investigate and audit the activities of a successful environmental CBO so as to determine how it has successfully sustained its school and community environmental projects. The reason for this investigation was to inform other CBOs and the state environmental agencies that support them on how to sustain their environmental activities in community and school contexts. The investigation was designed as an interpretive case study, which used document analysis, semi-structured interviews and observations to gather data. The gathered data was analyzed through inductive analysis to interpret and audit reported activities. Analytical memos were used to represent key themes in relation to the successful operations of the organization. Through auditing and reporting the activities in the analytical memos, analytical statements were developed. Those statements guided the discussion and informed the study‟s findings and recommendations. After investigating this CBO, it was concluded that, their success is a result of the establishment of a networking forum with different stakeholders and parties, community involvement in different projects, partnerships with local schools to develop and expand their curriculum practice, CBO networking locally and internationally and finally, their participation in annual and continuous environmental competitions/projects/programs. The insights gained and lessons learned will be used to advice and support community based co-operatives in environmental learning activities in school and community contexts as part of my ongoing work.

- Description: Introduction: Although the hackneyed adage "one picture is worth a thousand words" defies proof and begs argument, the basic value of illustration in graphic communications is beyond dispute. Without attempting to put a relative value on illustration as compared with words, we can still be aware of the special effectiveness of images, in accomplishing communication goals. The roots of illustration go hack to prehistoric pictorial art of engraved or painted figures done on stone. The hand print can be interpreted as one of the first attempts at drawing. Prehistoric pictorial art depicted visually what could not be expressed by word or gestures some had religious significance, some the presence of myth, others plainly diadactic, showing daily life, social communication, the magic of the hunt, death, birth, group life and sexual symbolism. Little is known of the vast lapse of time between prehistoric art and the imagery that man devised in the service of developing civilisations at the dawn of history. With steadily increasing demands upon his skills, the artisan's mastery of the tools and materials progressed, so that by the beginning of recorded time he was in possession of the potential elements for printmaking. Yet the importance of communication, as we know it today, only developed centuries later with the motivating force of religion. The print could tell its story to those who could not read or write but could quickly grasp the meaning of a picture.

- Description: A case study carried out at Edgewood College of Education (Natal) attempted to demonstrate how in-house training could provide staff with the necessary computer literacy skills to integrate computer technology into lecturing and teaching programmes. The duration of the project was six months and during this time a group of thirty academic staff members were exposed to computer technology via practical experience, lectures and demonstrations. The results gleaned from the project show that most of the staff involved in the project developed sufficient computer skills to be of benefit in their professional and personal tasks. In addition the recognition of the value of word processing and desk top publishing led to the staff encouraging students to use these software packages in the preparation of coursework. Consequently the use of the computer resources increased noticeably in the six month period. One of the goals of the study was to show how staff, once computer literate, would make use of generic software to integrate computer technology into their lecturing programmes. This did not happen and the reasons for this failure are discussed.

- Description: The class of pseudo-differential operators with symbols from Sm (superscript) po̧̧ (subscipt)(Ωx IRⁿ) has been extensively studied.The main assumption which characterises this class of symbols is that a(x,Ȩ) є Sm (superscript)po̧̧ (subscipt)(Ωx IRⁿ) should have a polynomial growth in the Ȩ variable only. The x-variable is controlled on compact subsets of Ω. A polynomial growth in both the x and Ȩ variables on a C°°(lR²ⁿ) function a(x,Ȩ) gives rise to a different class of symbols and a corresponding class of operators. In this work, such symbols and the action of the operators on the functional spaces S(lRⁿ) , S'(lRⁿ) and the Sobolev spaces Qs (superscript) (lRⁿ) (s є lRⁿ) are studied. A study of the calculus (i.e. transposes, adjoints and compositions) and the functional analysis of these operators is done with special attention to L-boundedness and compactness. The class of hypoelliptic pseudo-differential operators in IRⁿ is introduced as a subclass of those considered earlier.These operators possess the property that they allow a pseudo- inverse or parametrix. In conclusion. the spectral theory of these operators is considered. Since a general spectral theory would be beyond the scope of this work, only some special cases of the pseudo-differential operators in IRⁿ are considered. A few applications of this spectral theory are discussed

- Description: Climate change has become indisputable judging from the observed global variations in precipitation, increases in average temperatures, rising average sea levels and melting of ice. The climate phenomenon has since evolved globally and it has been largely documented by scholars. Because of the increases in global temperatures, weather patterns have also changed. This change has resulted in debates on climate change as well as how to respond to it. Various scholars across the world have expressed their opinions about climate change; its causes, impacts and adaptation. In addition, there has been a growing body of literature and studies focusing on smallholder farmers’ perceptions of climate change. Without a doubt, climate change will and has left a group of people, communities and countries vulnerable. In particular, developing countries and poor communities in sub-Saharan Africa are expected to be affected the most by the impacts of climate change. This is mainly because of the region’s dependence on natural resources and their limited capacity to adapt. Literature further adds that vulnerability is on condition of the community’s socioeconomic characteristics and physical surroundings. Climate change variations pose a threat to the agricultural sector and food security of households relying on subsistence farming for survival. Climate variations such as decrease in rainfall and increased hot seasons have been reported to have led to a decline in food production, death of livestock and outbreaks human and animal diseases. The study’s main aim was to determine the smallholder farmers’ perceptions of climate change and adaptation strategies in Raymond Mhlaba, Port Saint Johns’ and Ingquza Hill local municipalities. Particularly, the study looked at the factors influencing these perceptions and the factors affecting the smallholder farmers’ choice of adaptation strategies used in response to climate change. Investigating perception provides insights into the fundamental drivers of behavioural changes in the face of climate change. On their part, adaptation options are greatly shaped by the nature of an individual’s behaviour. The study was carried out in 3 local municipalities (Raymond Mhlaba, Port St Johns’ and Ingquza Hill) in the Eastern Cape, South Africa. The research design applied in this study was cross sectional design where data are collected at a single point in time. Multistage sampling technique was used in selecting respondents from the local municipalities. Stratification was then done to group farmers according to their vi wards and locations. Lastly, purposive sampling was used to select households and smallholder farmers practising crop and livestock production. A total of 211 smallholder farmers constituted the sample size for the study. A close-ended questionnaire was used to conduct structured interviews of household heads. The study utilized both qualitative and quantitative approach. Data collected were coded and entered in Microsoft Excel and transferred to Statistical Package for Social Scientists (SPSS, version 25) for analyses. Descriptive statistics was used to determine the climate change perceptions of smallholder farmers and also to explore the adaptation strategies used by farmers to cope with the impacts of climate change. The findings were explained using frequencies, means and variances. Multinomial Logistic Regression (MNL) was used to determine the factors affecting the choice of adaptation strategies used by smallholder farmers and the probability that a farmer would choose a particular strategy. The results from the study revealed most of the respondents as being able to identify the perceived changes in climate with the environmental changes that they observed. The respondents perceived climate change as an increase in drought period, increase in average temperatures, decrease and variations in rainfall, shortened growing season, crop failure, pests and diseases. However, most of the smallholder farmers disagreed with the frequency of flood incidences as they have not experienced these in their areas. In terms of responses to these changes in climate, the smallholder farmers have used a number of adaptation strategies to cope. Most of the farmers used crop diversification, organic manure, soil and water conservation practices, while others simply did not adapt and some used all the available adaptation strategies identified in this study. The results from the MNL revealed that occupation, household size and years spent in school (education) generally had a positive influence on the choice of adaptation strategy used by smallholder farmers. On the other hand, age; farming systems and membership of a farmers’ association were negatively affecting the smallholder farmers’ choice of adaptation strategy to use in response to climate change. Much support is needed in terms of disseminating information and knowledge among smallholder farmers about climate change and its adaptation strategies. This can be possible through improving extension services, and providing credit to smallholder farmers

- Description: The Autoregressive Distributed Lag model was used to estimate and analyse the relationship between crude oil prices and the trade balance of South Africa. This study estimated the trade balance model and analysed the relationship between crude oil prices and the trade balance of South Africa from the period 1990 to 2015. The bounds cointegration test confirmed the existence of a long-run relationship between the trade balance and real oil prices, real effective exchange rate, domestic income, real interest rate and the inflation rate. The results confirm that changes in oil prices have a negative impact on the trade balance whereas, currency devaluation, real interest, inflation rate and domestic income had a positive effect on the trade balance. The negative sign and significance of the Error Correction Term and diagnostic tests confirmed the reliability of the results.
