Stress and burnout in the Methodist ministry - towards a holistic helping model.

Sharpe, Philip A. J. January 2002 (has links)
The hypothesis that underpins this dissertation is that a holistic helping model relevant to addressing Burnout in the ministry needs to have as its major focus, the prevention of Burnout. Adequate internal and external supports need to be in place to act as buffers and mitigate against the unique stressors of ministry. A reactive response, seeking to address the consequences of Burnout is considered an inadequate response. Preventative measu res are viewed as far more effective and desirable. Recently the writer's car engine overheated. The problem began in an insignificant way, a rubber hosepipe began to perish, nobody noticed . Eventually under constant and intense pressure from superheated water flowing powerfully through the engine's cooling system, the hosepipe burst. It only took a few moments for the engine to overheat, causing serious damage. The cost of replacing the rubber hose would have been under one hundred rand. The labour time would have been under a half an hour. To repair the damaged engine after the pipe had burst and the engine had overheated cost thousands and the labour took several days. To repair or heal a person is far more complex and not always possible. When the stressors build up and nobody appears to notice or care, when the person is unable to diagnose for themselves, that they are near to breakdown or Burnout. When the person does not know who, what or where to turn to , and when the person has inadequate internal and external coping mechanisms - this type of emotional breakdown is far more serious than any burst pipe. Unlike in the example above some things cannot be repaired. Therefore the emphasis needs to be on preventing the ' hosepipe from ever perishing '. In the writer's opinion the many stressors that are common to ministry can become so overwhelming that breakdown or Burnout become a real possibility . Adequate internal and ext ernal coping mechanisms can be effective buffers to prevent such stressors becoming catastrophic. To ascerta in how serious the problem of stress is and its main consequence in the context of th is dissertat ion, Burnout, twenty of the fifty active Methodist ministers in the Nat al West District were asked to participate in a study. All twenty received the Burnout Inventory found in Appendix B of this document . The ministers approached were select ed in order to adequately represent a cross - section of the Meth odist Ministers in the District. A fair representation of gender, race and age were key considerations. The respondents were however, all white ministers, men and women, many of whom had worked in cross - cultural contexts. The available experts in the field, the woman psychologist , the professor and the minister with a history of successful cross - cultural work, were also white. In the writer's opinion black academics in the Methodist Church have focused more upon social issues and issues of social justice, than intrapersonal or psychological stresses with in the ministers themselves. This dissertation is therefore the outcome of mainly the experiences and insights of white ministers and therefore its response to the impact of Burnout among black Methodist ministers is limited. The ministers were asked to indicate which, if any of the twenty four responses that make up the Burnout Inventory, they agreed with. The respondents were also asked to indicate their gender, age and race, but not to record their names to ensure confidentiality. The limited number of twenty was important as all who responded were given the opportunity, if they chose to, of discussing their responses with the writer in a confidential environment. Some of these responses, with the permission of the respondents, provide the personal insights on Burnout recorded in Chapter One (p13). Chapter One deals with the nature of stress and th e unique stressors of ministry. Chapters Two and Three are in the writer 's opinion vital, in that in addition to the unique stressors common to all who minister, the specific stress of cross - cultural ministry is considered in Chapter Two. In Chapter Three the complexities of being a woman in ministry are discussed with reference to facing the sin of patriarchy. Both Chapter Two and Chapter Three have suggested Models presented at the end of each to address the very specific stressors people who engage in cross - cultural ministry and women who minister encounter. In Chapter Four the Burnout of the Prophet Elijah is discussed and a Holistic model towards the prevention of Burnout in the ministry is proposed . This model is called the Tripod model. Six in - depth interviews are recorded. In Chapter Two an Indian pastor suggests insights into the traps and pitfalls associated with cross - cultural ministry . Two women ministers in Chapter Three, express their thoughts and experiences of being a woman in ministry and in Chapter Four three experts in the field of ministry Burnout are interviewed, whose thoughts and ideas are integrated in order to develop the Tripod Model and the additional suggestions associated with a holistic model towards the prevention of Burnout in the ministry . What of the responses received? Is stress and Burn out really such a big issue? Is the ministry really so stressful? Five of the black ministers approached failed to respond. Fourteen of the fifteen responses received indicated that it really is a serious issue. Eight out of the fifteen indicated more than six areas of concern in the Burnout Inventory . Six out of the remaining seven indicated between two and five of the statements, questions were relevant to them and their experience of ministry . Only one, a woman minist er who was later interviewed in - depth and whose interview is recorded in Chapter Three, indicated none of the statements, questions as relevant to her life. The reason for this response is most surprising and totally unexpected. This dissertation focuses on a preventative model in relation to Burnout in the ministry. What of those who are experiencing or who have already Burned out? Is there hope? At the end of Chapter Four God's response to the prophet Elijah is considered and how God ministered to him to facilitate healing . This however is far from the ideal. When it comes to the concept of deep wounds to the human soul, prevention is most definitely preferable to cure. / Thesis (M.Th.)-University of Natal, Pietermaritzburg, 2002.

Managing an emerging region : A study of how MNCs manage uncertainty in a Southern African context

Axelsson, Markus, Olofsson, Andreas January 2016 (has links)
Title: Managing an emerging region – A study of how MNCs manage uncertainty in a Southern African context Authors: Markus Axelsson & Andreas Olofsson Supervisor: Cecilia Pahlberg Research question: How are Swedish business-to-business MNCs reducing perceived uncertainty when operating in the Southern African Development Community? Purpose: Provide a deeper understanding of how Swedish MNCs from diverse industrial backgrounds are managing uncertainty when operating in the Southern African Development Community (SADC). This study further aims to add to an acknowledged theoretical gap in international business research by providing a contextual contribution towards the Southern African region to the field of internationalization management. Method: A qualitative research method including semi-structured interviews was used to gain in- depth understanding of how Swedish B2B MNCs manages uncertainty within SADC markets. For the analysis, a theoretical framework based on uncertainty management, knowledge and network theory was developed into a conceptual model, carried out when gathering empirical data. Conclusions: The findings suggest that gaining experiential knowledge was vital to reduce perceived uncertainty among Swedish B2B MNCs operating in SADC markets. Experiential knowledge was obtained through operations within the markets, which over time resulted in enhanced market commitments and thereafter increased experiential knowledge. Knowledge was further exclusively shared within networks, where gaining network insidership was essential. To gain network insidership in SADC markets, findings suggest that becoming localized in the market to gain legitimacy is beneficial and achieved over a longer period of time. Finally, findings indicate that South Africa could be used as a gateway into Southern Africa, where firms’ can gain valuable experiences, relationships and an understanding of business practices, which can reduce the perceived uncertainty towards other SADC markets.

Humanity and salvation : exploring concepts of humanity within the spirituality of Wesley's understanding of salvation and African perspectives within the Methodist Church of Southern Africa.

Matthew, Lauren Claire. January 2013 (has links)
This thesis seeks to explore the concepts of humanity within Wesley’s soteriology and African perspectives in response to the call of the leadership of the Methodist church of Southern Africa (MCSA) to develop theology that is informed by our Southern African context. The central problem of the paper attempts to understand how people within the life of the MCSA interact with an understanding of humanity that is formed within the frameworks of Nguni and Sotho culture as well as Christian perspectives. The thesis maps Wesley’s anthropology through his own experience of God and particularly within the trajectory of his soteriology. It also seeks unpack an understanding of humanity within the framework of Ubuntu. In attempt to ground the conversation within the lived experience of the MCSA the paper also draws in data from two focus groups that are comprised of laity and ministers in training, respectively as well as through feedback from questionnaires that the participants in the two focus groups completed. The thesis makes use of an interpretive qualitative approach to explore the interplay of the different world – views in the lives of the participants as they share who they understand themselves to be and why they hold those particular views. The paper concludes with the observation of a pattern within the feedback from the participants that within the lives of the participants there seems to be a difference in their theoretical conception of humanity and their lived experience of their humanity. Within their theoretical understanding the participants were able to draw equally from their cultural perspectives and their Christian understanding, whilst within their lived experience, participants drew their understanding mainly from their Christian perspectives. / Thesis (M.A.)-University of KwaZulu-Natal, Pietermaritzburg, 2013.

Water regime requirements and possible climate change effects on Fynbos Biome Restionaceae

Ayuk, James January 2018 (has links)
Philosophiae Doctor - PhD / The Cape Floristic Region (CFR) of southern Africa is one of the world’s most unique biodiversity hotspots. However, this biodiversity continues to be threatened by habitat loss due to rapid urbanisation, agriculture and alien vegetation encroachment, and now, by future groundwater extraction and climate change. Previous work had shown that soil moisture is important in structuring wetland plant communities at fine-scale. What is not fully known, however, is how the spatial distribution of species at a local scale is related to soil hydrology and what the response in the future of species distributions will be to perturbations arising from changes in climate or subsurface moisture in the future. The current research investigated the water regime of the Restionaceae which is a key family in the Fynbos biome and the implications of possible changes in soil hydrology caused by climate change in communities within this region. The Restionaceae were particularly appropriate because they are shallow rooted perennials with the ability to tolerate a wide range of water regimes which allows them to successfully co-habit within mixed plant communities as segregated clusters along fine-scale hydrologic gradients. Vegetation survey counts for the presence of these species along with measurements of soil water table depth and moisture content data generated from eight small-scale plots (50 x 50 m) were used to investigate the possible hydrological niches and to envision the potential impacts of a substantial reduction in rainfall and an increase in temperature as projected by Global Climate Models (GCMs) on the structure of Restionaceae communities in seasonal wetlands by 2100. A comparative analysis of the effects of two extreme Representative Concentration emission Pathways (RCP2.6 and RCP8.5) on significant hydrological variables to plant water regimes was carried out. The IPCC AR5 report describes the RCP8.5 emissions scenario as the likely ‘business as usual’ scenario where emissions continue to rise through the 21st century while the RCP2.6 scenario assumes that emissions peak between 2010 and 2020 and substantially subside thereafter.

Spatial and temporal variation in domestic biofuel consumption rates in southern Africa

Tshikalanke, Rabelani Phillip 04 December 2008 (has links)
Biomass burning is an important source of trace gases such as CO2, CO and NO, which influence regional and global atmospheric chemistry. Biomass is burnt in bush fires as well as in households as an energy source. Even though there have been numerous studies on domestic biofuel use in Africa over the last two decades there is still a lack of consumption data on the continent. Biofuel is used in rural and urban areas in Africa, but this project focuses on rural consumption. This project aims to quantify biofuel use at representative rural sites around southern Africa and to investigate the spatial and temporal variation. Three sites, one in the south, central and northern parts were selected in each of seven countries (Botswana, Namibia, South Africa, Mozambique, Zambia, Zimbabwe and Malawi). Consumption rates for all fuel types were determined by weighing the fuel used throughout the day. The survey was conducted during the months of May 2003 to February 2004. The forms of biofuel used over southern Africa were found to be wood, charcoal and to a lesser extent maize residue. To obtain a consumption estimate for the whole of rural southern Africa consumption values for Swaziland and Lesotho from previously studies were included. The total annual rural fuelwood consumption in southern Africa is estimated to be 54.7 ± 3.5 Tg with an average daily consumption of 2.55 kg person-1 day-1 . South Africa has the highest consumption of wood and Swaziland the least. While fuelwood was used in all countries charcoal was only consumed in the rural areas of South Africa, Zambia and Mozambique. Rural southern Africa is estimated to consume 8.1 ± 0.8 Tg of charcoal per year. Malawi was the only country to consume maize residue at an average rate of 0.51 ± 0.16 kg person-1 day-1, leading to a consumption of 1.8 ± 0.1 Tg yr-1 over the whole region. The total rural biofuel consumption over southern Africa was estimated to be 64.6 ± 3.6 Tg yr-1. Namibia and South Africa had increased consumption rates between August and October, and Zambia shows slightly higher consumptions between May and July. The other countries show little monthly variation with no specific seasonal trends. There was a slight positive relationship (r2 = 0.168; p = 0.065) between consumption rate and altitude, but the data is very scattered due to monthly variation. Slopes are only shown to be significant between January and March. Altitude is therefore not shown to be a significant controlling factor of biofuel consumption in this study.

Interactions between sexually transmitted infections and human immunodeficiency virus in Southern Africa

Htun, Ye 26 February 2007 (has links)
Student Number : 9813645X - PhD thesis - Faculty of Health Sciences / Epidemiological information on sexually transmitted infections (STIs) is necessary to assess the magnitude of the burden of infections, to identify vulnerable population groups, to mobilise resources for intervention activities and to monitor the impact of these activities. In addition, specific STI surveillance systems, such as studies on the relative prevalence of aetiological agents of STI syndromes and their antimicrobial susceptibility patterns, are aimed at improving patient care. The studies included in this thesis were designed and implemented to improve our understanding of the epidemiology of STIs and HIV infection in southern Africa. In all the study populations, we observed that high level STI epidemics preceded the explosive spread of HIV infection among high-risk individuals. The studies reported here also demonstrate the importance of triangulating data collected from different recommended STI surveillance components, using a tiered surveillance approach. The studies reported here also explored the bidirectional interactions of HIV and STIs. We observed that different STIs have shown different magnitudes of interaction with HIV infection. We found particularly strong interactions between genital herpes and HIV. At the individual level, HIV-seropositive patients with genital herpes were more frequently found to have atypical clinical presentations, delays in spontaneous healing, longer duration of HSV shedding and increased association with HIV shedding from ulcer and genital exudates. Mixed infections involving chancroid and genital herpes were found to be common, particularly in HIV-seropositive patients. The effectiveness of syndromic treatment targeting only bacterial causes of genital ulceration was significantly reduced due to persistent ulcerations as a result of co-infection with genital herpes. The successful treatment of herpes in men and women was found to be associated with a decline or cessation in HIV shedding into ulcer exudates or genital fluid. The studies have also shown that HIV plasma viral load is the main determinant for HIV shedding in both men and women presenting with STIs. As was the case with HSV infection, there was a strong association between HIV and HPV infection in both men and women. A higher prevalence of HPV infection was found among HIV-seropositive patients in our study population and this may reflect the higher frequency of recurrences and/or longer duration of infection (i.e. persistency). The studies also found that the biological false positive reactions in syphilis serology (i.e. RPR) are not a common occurrence in our HIV-seropositive study population. On the other hand, syphilis serology could be falsely negative in patients with PCR-confirmed primary syphilis who are co-infected with HIV and other aetiological agents causing GUD. In conclusion, the findings of our studies have supported the bidirectional nature of interactions between conventional STIs and HIV infection in southern Africa.

African equity markets integration: a case study of COMESA

Mundonde, Justice January 2017 (has links)
This thesis is submitted in fulfilment of the requirements for the degree of Master of Management in Finance and Investment. Faculty of Commerce, Law and Management 2017 / The vicious quest for higher risk-adjusted returns through diversification of portfolios has seen an enormous amount of foreign capital flows into new emerging markets. However, the success of any strategy profoundly depends on the degrees of comovements among markets - higher comovements limit the possible gains from diversification. It has been argued that the very act of chasing after these diversification benefits, which mainly includes financial globalisation, has actually resulted in the erosion of the benefits themselves. In addition, aspects such as international trade, the establishment of trade blocs and liberalisation of market controls has further reduced these diversification benefits. In this study, the long-run cointegration, short-run causality and volatility linkages were examined using six COMESA markets indices. The goal of the study was to ascertain whether the establishment of this bloc has resulted in increased association among the member markets. The astonishing rate at which globalisation has been growing at has drawn with it both opportunities and risks for investors. The Engle-Granger, the Johansen cointegration technique and the ARDL test methods revealed that the markets integrated in the long run, a result indicative of low diversification benefits across COMESA markets. However, the weak short-run causality from the causality tests revealed that despite the strong long-run relationship, an active investment strategy that seeks to diversify portfolios in the short-run could still yield enormous diversification benefits. A subsequent examination of the volatility linkages using generalised autoregressive conditional heteroscedasticity models revealed that uniformity of volatility structures in terms volatility persistence, leverage effects and risk premium across the markets, indicative of the high likelihood of volatility spill-overs across the markets. This implies that, despite the weak short-run causality, the benefits from short-run diversification can still be quite low due to the high likelihood of volatility spillovers across these markets. In light of these results, investors within the COMESA markets should rather focus on other markets outside the COMESA as diversification destinations. / MT2017

Gene flowanalysis of anopheles arabiensis (Diptera:culicidae) populations in southern africa using microsatellite DNA markers

Mouatcho, Joel Claude 26 October 2006 (has links)
0009014A Msc thesis Science Animal plant and environmental sciences / Anopheles arabiensis is considered an important vector of human malaria in the southern African region where the disease is the major cause of morbidity and mortality. Gene flow plays an important role in malaria control with the spread of insecticide resistance. The main objectives of this study were to (i) measure the genetic variability within and between five populations (Botswana, Namibia, South Africa, Swaziland and Zimbabwe) of wild An. arabiensis and (ii) estimate the level of gene flow between natural populations across the Southern-limits of An. arabiensis. A total of 1225 An. arabiensis specimens were identified out of 1300 mosquitoes collected from 2000-2003 with the sample sizes ranging from 180-292 per country. Variation at four microsatellite markers was investigated on non-denaturing polyacrylamide gels. The results showed fewer variations between populations (2.96%) than within populations (82.60%) suggesting considerable homogeneity. However, estimates of gene flow (Nm) calculated from mean FST and RST statistics were relatively low, 1.14 and 1.19 respectively, suggesting somewhat restricted gene flow between populations. The occurrence of gene flow within subpopulations of An. arabiensis in Zimbabwe but not in South Africa is interesting with regard to the spread of insecticide resistance in Zimbabwe. The results presented here are obviously subject to the limitations inherent in manual, silver staining method of analysing microsatellite DNA markers. It is possible that a different set of results would be obtained if an Automated Sequencing Analyzer were used. ii

A política externa de Moçambique e sua inserção no processo de integração regional na África Austral

Massangaie, Arnaldo Timóteo January 2017 (has links)
A inserção internacional de Moçambique é um processo que ocorreu em fases, tendo se iniciado com os esforços empreendidos na década de 1960 pelo Dr. Eduardo Chivambo Mondlane, Primeiro Presidente da Frente de Libertação de Moçambique (FRELIMO). Visando criar o isolamento internacional do regime colonial Português e obter o apoio necessário para a causa da independência de Moçambique, Mondlane estabeleceu contatos com governos de vários Estados do mundo incluindo países ocidentais, países progressistas africanos e países socialistas, projetando, deste modo, a imagem de Moçambique no mundo. Iniciada com as decisões tomadas no Segundo Congresso da FRELIMO realizado em 1968, a política externa de Moçambique tinha em vista “criar mais amigos e poucos inimigos”, num contexto de bipolaridade ideológica que caracterizava a guerra-fria. O novo contexto internacional emergente no período após o fim da guerra-fria viria a originar uma redefiniçao desta política que passou a ser definida como de “criar mais amigos e mais parceiras”. A nível da região da África Austral a FRELIMO considerou sempre que a independência de Moçambique só seria completa com a libertação de todos os países da região que ainda se encontravam sob a dominação de regimes coloniais e minoritários tendo dado o seu apoio incondicional à luta de libertação do Zimbábue, África do Sul e Namíbia, para além do seu grande empenho no processo de cooperação e integração regional. É neste contexto que se pode enquadrar esta tese cujo tema é “a política externa de Moçambique e sua inserção na região da África Austral” a qual procura, através de uma vasta revisão bibliográfica, analisar os contornos que estiveram à volta da afirmação de Moçambique como Estado reconhecido no concerto das nações tanto a nível regional como internacional. / The international insertion of Mozambique is a process that took place in phases, starting with the efforts made in the 1960s by Dr. Eduardo Chivambo Mondlane, First President of the Liberation Front of Mozambique (FRELIMO). In order to create the international isolation of the Portuguese colonial regime and obtain the necessary support for the cause of Mozambique's independence, Mondlane established contacts with governments in several states of the world including Western countries, progressive African countries and socialist countries, thus projecting the image of Mozambique in the world. Initiated by the decisions taken at the Second FRELIMO’s Congress held in 1968, Mozambique's foreign policy aimed to "create more friends and few enemies" in a context of ideological bipolarity that characterized the Cold War. The new emerging international context in the period after the end of the Cold War would lead to a redefinition of this policy, which was defined as "creating more friends and more partners". At the level of the southern African region FRELIMO always considered that Mozambique's independence would only be complete with the liberation of all the countries of the region that were still under the domination of colonial and minority regimes and gave its unconditional support to the liberation struggle in Zimbabwe, South Africa and Namibia, in addition to its strong commitment to regional cooperation and integration. It is in this context that one can frame this thesis whose theme is "the foreign policy of Mozambique and its insertion in the region of Southern Africa" which seeks, through a vast bibliographical review, to analyze the contours that were around the affirmation of Mozambique as State recognized in the concert of nations at both regional and international levels.

The effects of minerals on reservoir properties in block 3A and 2C, within the orange basin, South Africa.

Salie, Sadiya January 2018 (has links)
>Magister Scientiae - MSc / The reservoir quality of the Orange Basin, offshore South Africa is known to be immensely impaired by the presence of authigenic minerals. The collective effects of burial, bioturbation, compaction and chemical reactions between rocks, fluid and organic matter conclusively determined the quality of reservoirs within the Orange basin. The aim of this study was to provide information on the quality of reservoirs within the Orange Basin. Data used to conduct this study include wireline logs (LAS format), well completion reports and core samples from potential reservoir zones of wells K-A2, K-A3 and K-E1. To accomplish the aim, petrophysical parameters were calculated, such as porosity, permeability and water saturation. Besides, depositional environments were identified using gamma ray log and core logging techniques. Thirdly, petrographic studies were supporting techniques in understanding how various minerals and diagenetic processes play a role in reservoir characterisation. Geophysical wireline logs (Gamma ray, Resistivity, Bulk density and Caliper) allowed for the estimation of the three main reservoir properties; namely: porosity, water saturation and permeability. The porosity calculations revealed a range of 3-18% for well K-A2, 2%-13% for well K-A3 and 3%-16% for well K-E1. The permeability’s ranged from 0.08-0.1 mD and 0.001-1.30 mD for K-A3 and K-E1, respectively. Thus, the findings of the petrophysical evaluation of the wells in Interactive Petrophysics indicated that the reservoir intervals of wells K-A2, K-A3 and K-E1 are of poor to good quality. Based on the core analyses, the depositional environment is mostly shallow marine, specifically tide dominated for well K-A2, sandstone channel for well K-A3 and intertidal environment for well K-E1. These environments were confirmed by XRD, revealing glauconite as the prominent mineral.
