Impact of access to free basic electricity on households' poverty in Buffalo City Municipality in the Eastern Cape

Mvondo, Jephthe M January 2010 (has links)
The study was premised on the truism that men have historically served in higher echelons of organizational management structures and women are under-represented. The principal objective was to explore the constraints faced by women in accessing higher leadership and senior management positions in public, private and non-governmental organisations in Zimbabwe. This study adopted the triangulation method, that is, qualitative and quantitative approaches. These mixed research methods, were upgraded by the feminist research methodologies, thereby making a contribution in the field of research. The study found out that the constraints that mostly hinder women from accessing leadership and senior management positions in public, private and NGOs were cultural practices, which represent levels of power and control that in turn hinder reforms; and women's socialisation into feminised roles. The study also found out that in most organisations, most females work under male leadership, and this traditional organisational culture, needs to be deconstructed and reversed in order to achieve gender equality. The study recommended for a human centric and integrated organizational management strategy for public, private and NGOs in Zimbabwe. The adoption of a human centric and integrated management approach should aim at gender equity and reduce women's under-representation. A human centred organizational culture has to be practiced, that would create organisational ethos that guide organizational management. An integrated organizational management approach should integrate all systems and processes into one complete framework, enabling people to work as a single unit, unified by organizational goals, shared vision and common values. The system should depend on a balanced mix of the masculine and feminine attributes. The approach should put its weight towards adoption of measures to attract, advance and empower women so as to benefit from their qualifications, experience and talent in a highly competitive environment.

Bancos de dados hierárquicos em inquéritos epidemiológicos / Hierarchical Databases in Epidemiological Surveys

Barbieri, Silvio Fernando 09 September 2008 (has links)
Introdução - A preocupação com a qualidade e disseminação dos dados em inquéritos é crescente no mundo. A integração entre banco de dados, planejamento da amostra, questionário e entrada de dados é fundamental para que resultados observados sejam válidos e precisos. A bibliografia pesquisada apontou que os inquéritos raramente produzem arquivos organizados, padronizados e prontos para disseminação, o que impossibilita estudar diferentes objetos de investigação com base em informações já coletadas. Objetivos - Implementar modelo hierárquico para entrada de dados em inquéritos epidemiológicos. Métodos - Foi utilizada a UML (Linguagem de Modelagem Unificada) para o projeto lógico e o Makeview do Epi Info para obtenção das estruturas de dados. Os testes foram feitos em um setor censitário do inquérito Acesso a Medicamentos - FAPESP. A documentação foi gerada no Makeview com ajuda de uma macro do Excel. Resultados - O modelo permite criar arquivos relacionais flexíveis, conforme a necessidade do objeto de estudo, com unidades estatísticas escolhidas dentre os 4 níveis hierárquicos: setor censitário, domicílios, indivíduos e questões específicas. Conclusão - A possibilidade de criar infinitas visões sobre os dados representa um avanço em comparação com o modelo plano. Deve ser usado como padrão em inquéritos epidemiológicos, pois permite estudar o efeito de conglomeração das unidades de análise, além de viabilizar a disseminação com dados organizados. O Epi Info pode ser usado para implementar modelos hierárquicos que considerem as variáveis do plano amostral. / Introduction - Concern about the quality and data dissemination in surveys is growing in the world.

Measuring and validating food insecurity in Embo, using the food insecurity scale and index

Msaki, Mark Mapendo. January 2010 (has links)
Measurement of household food insecurity is needed to identify the magnitude of food insecurity and assess the impact of development interventions. However, there is no commonly agreed measure of household food insecurity. While researchers continually experiment with new measures, the resultant measures are often complex and include numerous variables that still do not distinguish clearly between the food secure and the food insecure. This study set out to prepare a quick and convenient tool to measure household food security, using common household demographic and socio-economic variables commonly collected through a variety of household surveys. This has minimised data collection costs and assisted national food security units to continually measure and monitor household food insecurity. Food insecurity levels were estimated using data from a baseline survey conducted in a community in KwaZulu-Natal, South Africa. Food security was estimated using a number of measures, including food quantity (adequacy), dietary diversity, dietary quality, coping strategies employed and the Coping Strategies Index. The study found that household food availability varied across the two seasons over which data were collected. Only the percentile of sample households with adequate food intakes (one third of the samples) consumed enough food during the lean period when agricultural production was low. Households with inadequate food intakes also had consumed insufficient energy and lower micronutrient intakes during the period when agricultural produce was more abundant. Energy, iron and protein consumption was positively related to the consumption of adequate food. Energy intake was a relatively good indicator of protein and micronutrient intakes during the leaner period. Consumption of foods from three food groups, namely cereals, legumes and vegetables and fruits were necessary for adequate food intake. Cereals were the most important foods, forming the base of most meals, while fats and animal sourced foods were not widely consumed. Diversifying consumption through fruits and vegetables contributed significantly and positively to improved household food intakes. Household dietary diversity and dietary quality improved during the period of plenty. The application of coping strategies was strongly related to household food intake and diversity. Engaging in more coping strategies and having resultant higher Coping Strategy Index scores was strongly associated with household food inadequacy intakes and low food diversity scores. As expected, sampled households employed more coping strategies during the lean season. The strong and significant relationships between the Coping Strategies Index scores, the number of coping strategies practised by households and the household food intake indices (the Household Food Intake Index and Nutrient Adequacy Ratios) show that food intake is a strong indicator for household food security. The Household Food Insecurity Index and the Household Food Insecurity Scale were developed using 13 potential household demographic and socio-economic variables to identify the food-insecure households. The results of these two new measures were correlated with the results of the common measures reported above and found to be useful determinants of food security. The study found that while the Household Food Insecurity Index explained the influence of demographic and socio-economic variables in household food insecurity, the Household Food Insecurity Scale is more convenient in application (easy data management and computation process), and it is strongly related to the Coping Strategies Index scores. Both the Household Food Insecurity Scale and the Household Food Insecurity Index were useful tools to measure household food security and differentiate between food security and food insecure households in Embo Community. More research is recommended to further test the usefulness of the proposed measures in various settings. / Thesis (Ph.D.)-University of KwaZulu-Natal, Pietermaritzburg, 2010.

Evaluation of the impact of a household food security programme in QwaQwa using a coping strategy index.

Majake, Mosela Paulina. January 2005 (has links)
The Free State Department of Agriculture distributed food security packages to Qwaqwa households in 2003. The purpose of distributing food security packages was to improve the food security status of poor households. Thirty households received food security packages to the value of R4500.00 each between March and May 2003. The packages were designed to include: garden fencing materials, gardening tools, winter and summer seeds, fertiliser, water hoses, twenty village chickens, chicken feed and a portable, ready made poultry cage. This study sets out to evaluate the impact of these packages distributed by the Department of Agriculture to Qwaqwa households by comparing dietary diversity, frequency of consumption, income sources, coping strategy applications and food security status. Maxwell et al 's (2003) Coping Strategy Index (CSI) was used to determine relative food security status. Data on household demographics, food consumption patterns and consumption coping strategies was collected from 30 recipient households and 30 non-recipient households whose names were on the waiting list for food security packages in Qwaqwa. The results of the study showed that the packages improved food security in recipient households. First, the frequency of consumption of most foods included in packages (carrot, beetroot, eggs as by-product of chicken and chicken) was higher among recipient households. Food consumption patterns improved in recipient households as more households diversified food intake. Second, some coping strategies applied by recipient and non-recipient households were similar, but the frequency of application of these strategies differed between households in the two groups. The frequency of application of similar strategies (eating less preferred food, purchasing food on credit, visiting friends to eat with them, restricting consumption of adults in order for small children to eat, borrowing food, sending children to visit relatives, skipping entire meal eaten in a day, reducing meal sizes, and sending household members to beg) was higher in non-recipient households. The classification of strategies according to severity levels (least severe, moderately severe, severe and very severe) was done by community members. Recipient households applied the least severe strategies and moderately severe coping strategies more than non-recipient households. Non-recipient households applied more severe and very severe strategies more often than recipient households. As a result, recipient households' average coping strategy index score was lower than that of the non-recipient households, suggesting that food security packages improved recipient households' food security status. Lack of suitable scavenging space for the chickens and lack of knowledge of freely available chicken feed constrained the impact of the packages on household food security. Recommendations include training of extension officers and households in village chicken rearing and harvesting of chicken feed. It is recommended that the Department of Agriculture should adhere to its original plan of giving twenty-month old chicken to households and should use the Coping Strategy Index for identifying food insecure households and monitoring and evaluation of the impact of the food security programme. / Thesis (M.Agric.)-University of KwaZulu-Natal, Pietermaritzburg, 2005.

Assessing the food security status of households participating in community gardens in the Maphephetheni uplands determined by the Household Food Security Access Scale.

Shisanya, Stephen Odede. January 2007 (has links)
While South Africa is nationally food secure, the m ajority of rural households are food insecure. Community and home gardens are widel y promoted to alleviate food insecurity. Households in the Maphephetheni Uplands , KwaZulu-Natal have come together to cultivate community gardens, producing food crops for consumption and selling surpluses. This study evaluated the contrib ution of community gardens towards alleviating food insecurity in the Maphephe theni Uplands. A survey was conducted among 53 participants of community garden s and their households. A questionnaire and focus group discussions were used to evaluate the following household food security measures: anxiety and uncer tainty about food supply; consumption of a variety of preferred foods; consum ption of sufficient quantities of food; and the prevalence of food insecurity. Eighty percent of the participating households had insufficient food intake, 72% consum ed food of inadequate quality and 89% were anxious and uncertain about food suppl ies. Among the households surveyed using the Household Food Insecurity Access Scale, 88.7% were categorised as severely food insecure, often going a day withou t eating, going to bed hungry or running out of food for more than ten days in a mon th. Eight percent of households were moderately food secure, and three percent were mildly food insecure. No households were food secure according to the classi fication. Only 11% of the household food was sourced from community gardens, while 83% was purchased and six percent was sourced from home gardens. Limited community garden sizes, drought, floods, theft, pests and diseases were ide ntified by community gardeners as factors limiting the contribution of community gard ens to household food security. Community gardens have not alleviated food insecuri ty among the participating households. It is recommended that an investigation should be carried out on how productivity could be improved through appropriate crop husbandry practices to reduce crop loses. Since purchasing is the main sou rce of food among community gardeners, alternative income generating activities need to be investigated. / Thesis (M.Agric.)-University of KwaZulu-Natal, Pietermaritzburg, 2007.

Farming in the Langkloof : coping with and adapting to environmental shock and social stress

De Kock, Carinus 04 1900 (has links)
Thesis (MA)--Stellenbosch University, 2015. / ENGLISH ABSTRACT: During the period 2006-2012, the Langkloof area, situated in the Eden District Municipality, suffered severely from environmental shocks and social stress including drought, flooding, hail, wildfire, heatwaves and reduced labour demand. These events negatively impacted many farmers and their livelihoods. In response to these external shocks and stressors, large-, medium- and small-scale farmers adopted numerous coping and adaptive strategies. This study performed a comprehensive livelihoods analysis of large-, medium- and small-scale farmers in the Langkloof area, using the widely recognized sustainable livelihoods framework developed by the United Kingdom’s Department for International Development, with a particular focus on coping and adaptive strategies against severe environmental shock and social stress. Variables used in the analysis were the vulnerability context in which farmers pursue a livelihood; livelihood assets (social, human, financial, natural and physical); the policies, institutions and processes in the external environment that influence the degree of ownership and access to assets; livelihood strategies pursued; and the various livelihood outcomes ultimately produced. The analysis of coping and adaptive strategies employed by farmers during these periods formed an integral part of this study. Sixteen livelihood asset indicators were identified to determine the total assets (human, social, physical, financial and natural) of the farmers. After scaling the indicators, a Principal Component Analysis (PCA) was used to assign weights to each indicator and to subsequently calculate the total assets of each household. Regarding the coping and adaptive strategies employed by farmers against environmental shock and social stress, the average number of strategies was calculated for each household. Spearman’s rank correlations were calculated for total assets achieved (capacity) and the number of strategies employed against environmental shock and social stress. / AFRIKAANSE OPSOMMING: Die Langkloofgedied, geleë in die Eden Distriksmunisipalitiet, is gedurende die tydperk 2006-2012 geweldig geteister deur omgewings- en sosiale gebeure, wat droogte, vloede, hael, veldbrande, hittegolwe en ʼn gevolglike verlaagde arbeidsaanvraag sluit. Hierdie rampe het verreikende nadelige gevolge op boere se lewensbestaan gehad. Terwyl hulle lewensbestaan tot die uiterste uitgedaag is, is verskeie hanterings- en aanpassingstrategieë teen omgewingskok en sosiale stres geïmplementeer. Met die gebruik van die Verenigde Koninkryk se Departement van Internasionale Ontwikkeling se volhoubare lewensbestaansraamwerk is ʼn gedetailleerde en alomvattende analise van groot, medium- en kleinskaalboere in die Langkloof se lewensbestaan gedoen, met ʼn sterk skem op hul hanterings- en aanpassingstrategieë teen omgewingskok en sosiale stress. Die analise veranderlikes het die kwesbaarsheidskonteks waarin boere hul lewensbestaan aanpak; hul verskeie bates (menslik, sosiaal, finansieel, fisies en natuurlik); die beleide, instansies en prosesse in die eksterne omgewing wat toegang tot en eienaarskap van bates reguleer; hul lewensbestaanstrategieë; en die lewensbestaansuitkomste wat bereik word, behels. Die analise van die boere se hanterings- en aanpassingstrategieë geïmplementeer teen omgewingskok en sosiale stres gedurende hierdie tydperk was ʼn integrale rol van hierdie studie. Sestien aanwysers is geïdentifiseer om die totale lewensbestaansbates (menslik, sosiaal, fisies, finansieel en natuurlik) van die boere te bepaal. Nadat die aanwysers geskaal is, is ‘n Hoofkomponentanalise (PCA) uitgevoer om gewigte aan elke aanwyser toe te ken vir die berekening van totale bates van huishoudings. Die hanterings- en aanpassingstrategieë ingestel deur boere teen omgewingskok en sosiale stres, is die gemiddelde aantal strategieë per huishouding. Spearman se rangorde korrelasies is bereken vir die totale bates (kapasiteit) en die getal strategieë geïmplementeer teen omgewingskok en sosiale stres.

Rural livelihoods at Dwesa/Cwebe: poverty, development and natural resource use on the Wild Coast, South Africa

Timmermans, Herman Gerald January 2004 (has links)
This thesis uses the sustainable rural livelihoods framework to investigate the livelihoods of communities residing adjacent to a remote protected area on the Wild Coast. The communities living in the area are among the poorest in South Africa and are largely dependent on migrant remittances and state welfare grants for their survival. Soon after South Africa's first democratic elections in 1994, the communities lodged a land claim against the protected area on the basis of past removals. In 2001, their land rights to the protected area were restored, opening up new avenues for the development of the area. It is argued that livelihood systems in the area are complex, varied and dynamic, and that for development to be sustainable, it needs to be informed by a thorough understanding of the many factors that shape the context in which livelihoods are generated. The research is based primarily on 'in-depth' micro-studies of two villages in the area - Ntubeni and Cwebe. It includes a detailed assessment of the extent and distribution of poverty and the various factors that make households vulnerable to livelihood shocks. The role of the rich and diverse natural resource base, the property rights associated with it, and the under-development of infrastructure and services in the area, are discussed in relation to livelihood prospects. A systems approach is used to examine the various ways in which livestock husbandry, cropping, natural resource use, employment and welfare dependence interact. Finally, the thesis examines in some detail the distribution of household assets, livelihood strategies and livelihood outcomes between the two villages, and between households in different income groups.
