Building mature churches in Africa : a practical-theological study / Timothy Wendell Cantrell

Cantrell, Timothy Wendell January 2004 (has links)
In this thesis the researcher argues that churches in Africa are being planted rapidly but are not growing to maturity, which produces troubling consequences. The Baptist Union of Southern Africa (BUSA) is then given as a representative case study of church planting in Afiica, because from 1990 they have seen as many as 413 new churches started. Yet there is growing concern over the stability of many of these young churches and their leaders. Key leaders in the BUSA are calling for an analysis of the church planting and a greater emphasis on church strengthening and equipping. Next, the researcher lays the exegetical foundation for building mature churches, drawing from Acts and the Pauline epistles. In Acts, keys for the growth of the church are given. In Paul's writings, the researcher identifies the core principles and content used in establishing churches. Next come the field research findings that show the condition of churches and church planting in the BUSA The research was conducted through church leader surveys and key interviews, supplemented by observations of Christ Seminary faculty in their training of pastors from these churches. Some disturbing statistics and characteristics of these young churches emerge. The researcher then seeks to demonstrate how to analyse the health of churches and church planting in Africa by interacting with the field research in light of Scripture. An analysis is given of the strengths and weaknesses of the BUSA's younger churches, in the areas of their evangelism, their establishing of the members, and their entrusting of leadership. Cautions were given against unbiblical church growth trends. Finally, the researcher offers suggestions and strategies for building stronger churches in Africa. He states, "In order for the gospel to steadily advance through the BUSA or through any churches in Africa, mother churches and church planters must take responsibility for strengthening young churches until they have qualified elders and are mature, reproducing churches." / Thesis (Ph.D. (Pastoral))--North-West University, Potchefstroom Campus, 2004.

Effets des cultures intercalaires dans le maïs-grain, sur le rendement en grain, la qualité édaphique, et la teneur en azote inorganique des sols

Claude, Pierre-Phillippe January 1990 (has links)
The objectives of the study were to determine whether intercropped alfalfa (Medicago sativa L.), red clover (Trifolium pratense L.) or rye grass (Lolium multiflorum Lmk.) could simultaneously contribute to the nitrogen regime of grain-corn (ie: increased yield), improve edaphic quality, and decrease the level of inorganic nitrogen present in the soil after corn harvest. To achieve these objectives the seeding of the intercrops was delayed, the corn population was increased, and the red clover was spring-ploughed. / Fall-ploughed red clover maintained the mean weight diameter (MWD) of aggregates on the Ste-Rosalie clay. Spring-ploughed red clover on the other hand caused a decrease in bulk density in the top 10 cm of the Chicot loam. / The nitrogen-response of corn indicated that the intercrops did not contribute to the nitrogen regime of grain-corn. There were also indications that intercrops competed with corn for available inorganic nitrogen and water. The intercrops, however, did reduce the levels of soil inorganic nitrogen in the fall allowing for a possible decrease in the nitrogen load of soil percolates. / Despite the beneficial effect of nitrogen fertilisation on the organic nitrogen content of the soil, the presence of leguminous intercrops did not prevent the increase of the soil CN ratio.

Produção animal e de grãos de trigo duplo propósito com diferentes períodos de pastejo

Pitta, Christiano Santos Rocha January 2009 (has links)
Produzir trigo de duplo propósito possibilita ao agricultor dar ênfase às alternativas mais rentáveis em função da variação dos preços pagos pelos produtos, entretanto, a época de diferimento e os efeitos do pastejo sobre a produção ainda precisam ser elucidados. Diante disso, o objetivo do presente trabalho, conduzido na área do Instituto Agronômico do Paraná (IAPAR) na estação experimental de Pato Branco- PR, foi avaliar a influência de diferentes períodos de pastejo (0, 21, 42, 63, 84 e 105 dias) sobre a produção de grãos de trigo da cultivar BRS Tarumã e a produção animal de bovinos da raça Purunã com peso médio de 162 kg e idade de 10 meses, que permaneceram sob pastejo com lotação contínua e taxa de lotação variável. Durante o período experimental (abril a novembro de 2007), avaliou-se: massa, oferta e qualidade da forragem, carga animal, taxa de lotação, ganho de peso vivo por área e ganho médio diário e produção de grãos em delineamento experimental de blocos ao acaso com seis tratamentos e duas repetições. O pastejo pode ser executado com resultados eficientes para produção animal até os 88 dias, porém ocorre redução na produção de grãos de acordo com o aumento do período de pastejo. / The double purpose wheat production (animal and grain production) allows some flexibility in the crop livestock production system and permit to the farmers to choose the best alternative according to the prices paid to the products, although, the deferment periods and the grazing effects over the wheat production need to be studied. The aim of the present work, carried out at the Agronomist institute of Paraná (IAPAR), experimental unit of Pato Branco-PR, was to evaluate the effect of six grazing periods (0, 21, 42, 63, 84 and 105 days) over the wheat grain production, BRS Tarumã cultivar and the animal production of Purunã steers with average live weight of 162 kg and age of 10 months managed on continuous stocking rate. During the experimental period (April to November of 2007) were evaluated: forage mass, offer and nutritive value, intake, stocking rate, animal daily gain and gain per hectare and wheat grain production. The experiment was laid out as randomized complete (RCBD) block design with six treatments and two eplications. The grazing period can be kept until 88 days with efficient results to the animal production, however, the grains production decreased with grazing use.

Saúde e qualidade de vida: um estudo comparativo em duas comunidades rurais no Estado do Paraná

Yamada, Roberto Shigueyasu 30 March 2012 (has links)
Qualquer estudo sobre a cadeia produtiva do tabaco reconhece que o elo mais frágil do processo é o fumicultor. Neste estudo de caso abordou-se este complexo tema na perspectiva interdisciplinar, iniciou-se com contextualização da fumicultura como uma agricultura familiar especializada, a seguir uma analogia da folha do tabaco como duas faces de um desenvolvimento sustentável: o lado do bem refente ao lado econômico, e o lado do mal como as consequências na saúde publica. E finalmente os riscos e qualidade de vida no cultivo do tabaco. Um questionário semiestruturado baseado no instrumento Vigilância de Fatores de Risco e Proteção para Doenças Crônicas por Inquérito Telefônico (Vigitel) sob a responsabilidade da Secretaria de Vigilância em Saúde do Ministério da Saúde foi utilizado para captar algumas informações sobre saúde das comunidades. O instrumento genérico e de auto percepção, Medical Outcomes Study 36 – Item short form health survey (SF-36), traduzido e validado para o português foi utilizado para verificar se haveria diferença de qualidade de vida na saúde nas duas comunidades de diferentes sistemas de produção do tabaco; Itaiba com tabaco tipo Burley no município de Marmeleiro – Pr e, Volta Grande com tipo Virgínea no município de Irati - Pr, mostrou-se adequado nesta pesquisa. A confiabilidade dos domínios foi avaliada através do Coeficiente Alfa de Cronbach cujo resultado foi de 0,841 para Itaiba e 0,722 para Volta Grande. A validade dos domínios foi através da Correlação de Spearman cujos resultados foram positivos e estatisticamente significativos na maioria das correlações nas duas comunidades. Não houve diferença significativa no teste t de Student quando avaliada a variável localidade e atividade agrícola com os indivíduos das duas comunidades excluindo os aposentados. Havendo diferença quando utilizadas as variáveis de patologias como Hipertensão Arterial (HA), Diabetes (Db), colesterol, osteoporose em relação às dimensões que avaliavam o aspecto físico. Os indivíduos das duas comunidades conhecem a importância da utilização dos Equipamentos de Proteção Individual (EPIs), mas utilizam de forma precária. A compreensão do risco no trabalho da cultura do tabaco está prejudicada quando se refere à própria pessoa, como nas demais atividades agrícolas, os riscos parecem que afetam somente os outros indivíduos. Pela presença mensal do Agente Comunitário de Saúde (ACS) percebida pelo acompanhamento de hipertensos e diabéticos no Sistema de Informação de Atenção Básica (SIAB) do Ministério da Saúde; bem como menor consumo de automedicação, há um melhor acompanhamento da população da comunidade de Itaiba, município de Marmeleiro em relação à comunidade de Volta Grande, município de Irati. A comparação de qualidade de vida na saúde com mesmo instrumento na atividade agrícola poderá ser realizada futuramente com a construção de trabalhos semelhantes. / Any study on the tobacco production chain acknowledges that the weakest link in the process is the tobacco grower. In this case study, this complex topic was approached in an interdisciplinary perspective. It began with the contextualization of the tobacco growing farms as a specialized family-based agriculture, then an analogy of the tobacco leaf as two sides of a sustainable development: the good side related to the economic aspect, and the side of evil as the consequences on public health. And finally, the risks and the quality of life in the cultivation of tobacco. A semi-structured survey based on Surveillance of Risk and Protective Factors for Chronic Diseases by Telephone Inquiry (Vigitel) under the responsibility of the Secretariat of Health Surveillance, Ministry of Health was used to capture some information about the health of communities. The generic and self-perceptive instrument, Medical Outcomes Study 36 – short form health survey (SF-36), translated and validated into Portuguese, was used to verify whether there would be a difference in the quality of life in the health of two communities with different tobacco production systems: Itaiba with Burley type tobacco in the city of Marmeleiro – Pr, and Volta Grande with Virginea type tobacco in the city of Irati - Pr, and proved suitable in this survey. The reliability of the domains was assessed by using the Cronbach Alpha Coefficient, with results of 0.841 for Itaiba and 0.722 for Volta Grande. The validity of the domains was assessed through the Spearman Correlation, of which results were positive and statistically significant in most of the correlations in the two communities. There was no significant difference in Student’s t test when the variables location and agricultural activity were evaluated with individuals from the two communities, excluding retirees. A difference was observed when using pathologies such as Hypertension (HA), Diabetes (Db), cholesterol and osteoporosis as variables, compared to the dimensions that assessed the physical aspect. The individuals of the two communities are aware of the importance of the use of Personal Protective Equipment (PPE), but use it in a precarious way. The understanding of the risk involved in the work of tobacco growing is impaired when referring to oneself, as in other agricultural activities, the risks seem to only affect other individuals. With the monthly presence of the Community Health Agent (ACS), noticed by the monitoring of individuals with hypertension and diabetes in the Primary Care Information System (SIAB) of the Ministry of Health, as well as lower comsumption of self-medication, there is a better monitoring of the community population of Itaiba, city of Marmeleiro, in relation to the community of Volta Grande, city of Irati. The comparison of quality of life in health, with the same instrument in agricultural activity, may be performed in future developments of similar work.

Respostas agronômicas e ecofisiológicas de videira, cultivar BRS Violeta, influenciadas por sistemas de adubação

Malagi, Gustavo January 2011 (has links)
CAPES / O cultivo da videira no Paraná, especialmente na região Sudoeste, tem apresentado desenvolvimento ascendente em função da ampliação dos canais de consumo e das melhorias infraestruturais e de manejo que vem sendo adotadas. Porém, questões de ordem econômica como a elevação dos custos com fertilizantes e, questões técnicas como a falta de pesquisas voltadas ao desenvolvimento de um modelo produtivo sustentável, limitam ainda a expansão desta cultura. Assim, buscam-se alternativas que possam suprir carências de fertilizantes acessíveis economicamente e ao mesmo tempo eficientes agronomicamente. Busca-se também suprir as necessidades da sociedade por produtos alternativos voltados a um modelo de produção agroecológico. Assim, este trabalho teve por objetivo avaliar a influência de formulações à base de insumos alternativos, isolados ou em combinação com derivados do xisto, sobre o desenvolvimento, produção e qualidade dos frutos da videira. O trabalho foi desenvolvido na área experimental da Universidade Tecnológica Federal do Paraná, Campus Pato Branco, entre 2008 e 2011, utilizando-se dez tratamentos: T1: Fosfato Natural de Gafsa (FNG) + K2SO4; T2: FNG + PRB (Pó de Rocha Bioland®); T3: FNG + K2SO4 + GP (cama de Galinha Poedeira); T4: FNG + PRB + GP; T5: FNG + K2SO4 + MBR3 (Matriz Xisto 3); T6: FNG + PRB + MBR3; T7: FNG + K2SO4 + MBR3 + GP; T8: FNG + PRB + MBR3 + GP; T9: SFT (Superfosfato Triplo) + KCl + Uréia e T10: Testemunha Absoluta. Empregou-se o delineamento blocos ao caso com quatro repetições, utilizando-se videira cultivar BRS Violeta. Cada unidade experimental foi composta por sete plantas úteis, limitadas por duas plantas de bordadura. Os dados obtidos foram submetidos à análise da variância utilizando-se análise de contraste ortogonais em estrutura fatorial para comparação das classes de adubação. Verificou-se que a área foliar da cultivar BRS Violeta pode ser determinada com boa precisão pela equação ß : 0,2169(SCN S)² + 5,3642(SCN S) - 34,725 , substituindo o parâmetro SCNS pelo somatório do comprimento das nervuras secundárias das folhas. O uso de sulfato de potássio proporcionou aumento significativo do teor de potássio na camada superficial do solo, favorecendo a elevação da condutância estomática e da taxa fotossintética das folhas no verásion, a elevação do teor deste elemento nas cascas das bagas, e o aumento do teor de sólidos solúveis totais nas bagas durante a evolução da maturação. O uso do pó de rocha Bioland® e da matriz MBR3 proporcionou aumento do teor de fósforo na camada superficial do solo, possivelmente pela dessorção deste elemento por silício. A atividade microbiana do solo esteve relacionada também com o aumento do teor de fósforo pela mineralização do fósforo orgânico presente nos restos culturais da cobertura de inverno. Na safra 2010/11 a área foliar das videiras aumentou ignificativamente pelo efeito médio dos tratamentos com adubação. A produtividade por área não foi afetada significativamente pelos efeitos das adubações, assim como os teores de antocianinas e flavonóides na evolução da maturação. As avaliações pós-colheita não evidenciaram influencias dos tratamentos. Pelos tratamentos alternativos serem de baixa solubilidade, é esperado que seus efeitos sejam evidentes de médio a longo prazo. / Vineyards in Paraná, especially in the Southwest region, has shown upward development due to the expansion of the channels of consumption and infrastructural improvements and management that has been adopted. However, financial issues as the rising cost of fertilizers, and technical issues such as lack of research directed to developing a sustainable model of production, limit further expansion of this culture. Thus, attempts to find alternatives that can meet needs for affordable and fertilizer at the same time efficient crop. The aim is also supply the needs of society for alternative products aimed at a model agroecological. This study objective to evaluate the influence of formulations based on alternative inputs, alone or in combination with products derived from shale, on the development, production and fruit quality of grapevine. The study was conducted in an experimental area at the Federal Technological University of Paraná, Pato Branco Campus, between 2008 and 2011, using ten treatments: T1: Gafsa Rock Phosphate (GRP) + K2SO4; T2: GRP + RDB (Rock Dust Bioland®); T3: GRP + K2SO4 + TL (Turkey Litter), T4: GRP + RDB + TL; T5: GRP + K2SO4 + MBR3 (Matriz Shale 3), T6: GRP + RDB + MBR3; T7: GRP + K2SO4 + MBR3 + TL, T8: GRP + RDB + TL + MBR3; T9: TSP (Triple Superphosphate) + Urea + KCl and T10: absolute control. We employed a block design with four replications, using BRS Violeta vine. Each experimental unit consisted of seven plants, limited by two border plants. The data were subjected to analysis of variance using orthogonal contrast analysis in comparison to factor structure of the classes of fertilization. It was found that the leaf area of BRS Violeta can be determined by the equation ß : 0,2169(SCN S)² + 5,3642(SCN S) - 34,725 , replacing the parameter SCNs by the sum of the length of secondary veins of leaves, with good accuracy. The use of potassium sulfate provided significant increase of potassium content in the topsoil, causing high stomatal conductance and photosynthetic rate of leaves in verásion, raising the content of this element in the bark, berries and enhanced content of soluble solids in berries during the maturation. The use of basaltic rock powder Witimarsun MBR3 provided an increase of phosphorus content in topsoil, possibly by the desorption of this element in silicon. The soil microbial activity was also related with the increase of phosphorus content on the mineralization of organic phosphorus present in the debris of winter cover crops. In the 2010/11 crop leaf area of vines increased significantly by the average effect of fertilization treatments. The productivity per area was not significantly affected by the effects of fertilization, and it also happened with the anthocyanins and flavonoids on the maturation. Postharvest evaluations showed no influence of treatments. Alternative treatments are those of low solubility, so it is expected that its effects will be evident in the medium to long term.
