Abstract: in the region of janaúba, northern minas gerais state, brazil, banana yields are high due to the highly technical agriculture of the region, with intensive use of fertilizers and systematic plant disease and pest control. however, farmers frequently report a decline in banana yields, particularly when water from deep wells is used for irrigation. we therefore studied the effect of irrigation water from wells and from the gorutuba river on soil chemical characteristics of areas with banana cultivation. soil samples were collected to a depth of 100 cm in adjacent areas with and without irrigation. it was observed that the irrigation water from deep wells is of low quality and resulted in increased ph, ca2+ and mg+ levels in the soil. this resulted in high ca/mg and ca/k ratios, which are far above from the optimal range for banana plants. for soils irrigated with water from wells there was an increase of h2so4 - extractable p as a result of p precipitation with ca dissolved in water. the ph values of soil saturation extract were higher than the ones obtained during routine analysis. the concentration of soluble salts in soil solution observed within the soil profile at intermediate depths was due to leaching, especially in the 30-40 cm layer of soils irrigated with water deep wells.

Abstract: a cross section study was carried out in a farming community from nova friburgo, rio de janeiro state, brazil, to examine epidemiological, clinical and laboratory aspects of multiple exposure to pesticides in a representative sample of 102 small farmers. both males and females were submitted to an extensive protocol which included an occupation questionnaire, biological sample collection for toxicology analysis and clinical - general and neurological - evaluation. the toxicology test results showed light to moderate episodes of acute intoxication by organophosphorates either described by the farmers or observed during clinical examination. thirteen cases of delayed neuropathies (12,8%) as well as 29 cases of neural behavioral syndromes and psychiatric disorders associated to the continued use of pesticides were diagnosed. these results indicate recurrent multiple overexposures to high concentrations of different chemicals, with serious damage to vital functions, especially considering their young age (average 35 ± 11 years old) and the productive period in their lifetime. these results show how important it is to monitor multiple exposure to pesticides - a chain of events that may have major impacts on public health and the environment.

Abstract: from the participant observation of a group of capoeira in the city of natal/ rn, looks to show nuances of rationality tattooed body and gesture, from the game of capoeira. to this end, we apply the method of phenomenology proposed by merleau-ponty, based on the systematization of visual score as a methodological tool for the observation of gesture and body in the game of capoeira. it presents arguments from the intentionality of body experience in capoeira, saying the human society and culture, to the extent that the meaning of gestures and body tissues are in the mutual actions, established and recognized by the subjects.

Abstract: Retailers face a complex task in formulating prices strategies. While the goal of pricing is to lay down a general course of action, pricing methods are procedures which enable organizations to make their pricing decisions. The scope of this paper is to explore retail pricing goals along with the methods that are employed for pricing, and to investigate whether the methods employed succeed in achieving the objectives. It was found that the companies used in the sample are basically pursuing quantitative rather than qualitative objectives and that they lay emphasis on achieving sales and making profits by following market developments. Another significant factor was that, the firms in the sample seemed to attach less importance to customer-oriented methods and employ the traditional methods of costing, probably due to their simplicity.

Abstract: No varejo, os gestores possuem uma delicada e complexa tarefa na formula o das suas estratégias de precifica o considerando-se os múltiplos produtos e servi os disponíveis. Enquanto os objetivos de pre o fornecem uma dire o geral para a o, as estratégias de precifica o s o os passos ou procedimentos pelo qual as organiza es atingem suas decis es de pre os. O escopo desse trabalho é explorar os objetivos de pre os que as empresas varejistas buscam juntamente com as estratégias que adotam para precificar seus produtos e servi os; e investigar se os objetivos de pre o est o associados com as estratégias de pre o adotadas. Para responder aos objetivos desse trabalho, optou-se por realizar uma pesquisa de cunho quantitativo-descritivo por meio de levantamento tipo survey. A sele o da amostra é n o probabilística e por conveniência dos pesquisadores. Constitui-se de 300 empresas varejistas de diversos portes localizadas na cidade de S o Paulo. Como resultado descobriu-se que as empresas da amostra est o fundamentalmente perseguindo objetivos quantitativos no lugar de objetivos qualitativos, com uma forte ênfase na realiza o de vendas e lucros seguidos pelo desenvolvimento de mercado para a organiza o. Outro ponto importante na discuss o dentro das estratégias de varejo, as empresas da amostra parecem dar uma menor importancia a métodos orientados ao cliente. Essas empresas empregam com mais freqüência o método tradicional de custos, provavelmente devido a simplicidade deste método.

Abstract: This study intends to discuss the importance of building a co-operative strategic relationship in business, since it became an important precedent of success in business. Researchers have demonstrated that partnership and alliances have an important role in establishing a competitive advantage based on a firm’s resources. For the objective in this research, we commence with an investigation in two real-state networks of which we adopt as a methodological pillar, the qualitative typology of investigation, due to it providing the most adequate observations. Methods utilised for this investigation included: a semi-structured interview; bibliographic research and non-participant. It concludes to demonstrate that the relationship researched proves the importance of a well-meaning cooperative strategy for companies acting in network formats. As a direct consequence, the access to partners and their resources could be considered the most strategic object analyzed. As a methodological limit, the fact this research is qualitative must be underlined and noted. These findings have little room for generalization when compared with quantitative research. The biggest practical implication is to allow managers participating in a network to perceive the strategic importance of this relationship. The manager must consider, within the boundaries of their formulated strategies, the development and maintenance to: grant them access to partners and their resources and the ability to build a strong position within the network in order to influence other partners. Esse trabalho visa discutir a importancia dos relacionamentos estratégicos de negócios de forma cooperativa, pois se têm tornado um importante antecedente de sucesso nos negócios. Estudos mostram que alian as e parcerias possuem um importante papel na moldagem das vantagens competitivas baseadas em recursos da empresa. Para a concretiza o dos objetivos propostos nesse estudo, iniciou-se uma investiga o em duas redes imobiliárias e adotou-se como pilar metodológico, a tipologia qualitativa de investiga o, por fornecer a melhor adequa o ao fen meno observado. Foram utilizados como instrumento: entrevista semi-estruturada, pesquisa bibliográfica e observa o n o-participante. Conclui-se que os relacionamentos se mostraram importantes e estratégicos para empresas que est o atuando em formato de redes. Como conseqüência direta, o acesso aos parceiros e aos recursos que esses possuem pode ser considerado, como o mais estratégico dos pontos analisados. Como limite metodológico deve ser citado o fato de a pesquisa ser d

Abstract: objective: to reduce cost and time associated with household sampling process and to assess the feasibility of shared use of address data file of census enumeration areas in several epidemiological surveys using updated information from the national survey of households (pnad). methods: address data file comprising 72 census enumeration areas was kept as primary sampling units for the city of s?o paulo. during the period 1995-2000, three distinct household samples were drawn using the two-stage cluster sampling procedure. geographic information system (gis) technology allowed delimiting boundaries, blocks and streets for any primary sampling unit and printing updated maps for selected sub-samples. results: twenty-five thousand dwellings made up the permanent address data file of the master sample. a cheaper and quicker selection of each sample, plus gathering information on demographic and topographical profiles of census enumeration areas were the main contribution of the study results. conclusions: the master sample concept, integrated with gis technology, is an advantageous alternative sampling design for household surveys in urban areas. using the list of addresses from the pnad updated yearly, although limiting its application to the most populated brazilian cities, avoids the need of creating an independent sampling procedure for each individual survey carried out in the period between demographic censuses, and it is an important contribution for planning sampling surveys in public health.

Abstract: OBJETIVO: Reduzir as despesas e o tempo associados ao processo de amostragem de domicílios e mostrar a viabilidade de uso compartilhado dos cadastros de endere os entre vários inquéritos epidemiológicos, a partir da reciclagem de material produzido pela Pesquisa Nacional de Amostras de Domicílios (PNAD). MéTODOS: Cadastros permanentes de endere os foram construídos e atualizados para 72 setores censitários, e retidos como unidades primárias da amostra mestra do município de S o Paulo, SP. No período 1995-2000, sortearam-se três diferentes amostras pelo processo de conglomerados, em dois estágios. Opera es de sorteio e mapeamento das amostras foram automatizadas por meio da aplica o de tecnologia de geoprocessamento. RESULTADOS: Cerca de 25.000 domicílios comp em o cadastro permanente de endere os da amostra mestra. A produ o ágil e barata de cada amostra, aliada ao conhecimento acumulado sobre os perfis demográficos e topográficos dos setores censitários, pode ser considerada a principal contribui o dos resultados alcan ados. Verificou-se que o sistema proposto contrasta com a sele o de amostras independentes para cada investiga o "ad hoc", o que ainda é prática comum nas agências ou grupos que realizam inquéritos domiciliares. CONCLUS ES: A reciclagem das listagens anuais de endere os da PNAD, apesar de restringir a abrangência de replica o da experiência aos municípios mais populosos do País, evita a repeti o do processo de amostragem para cada inquérito; além disso, significa importante contribui o ao planejamento de investiga es descritivas na área da saúde pública. Quest es conceituais ou teóricas, decorrentes do procedimento operacional, foram facilmente superadas pela introdu o de técnicas estatísticas compensatórias.

Abstract: The cultivars Arbequina, Picual and Frantoio of Olea europaea are cultivated in severalMediterranean countries. In 1999, these cultivars were planted at three locations in the region of Coquimbo,an arid, Mediterranean-like area in Chile. A generalized linear modeling approach was used in view of thenon-normal distribution of the agronomic data sets. Fruit yield (harvests of 2002-2003), precocity (2002) andtree survival (after four growing seasons) differed significantly between the cultivars. Arbequina and Picualhad a positive effect on the yield. Picual was the earliest cultivar at two sites. The survival rate of Frantoio washigh at the three sites (90-100%), as opposed to Picual (56-83%). The approach of Generalized Linear Modelswas particularly useful where the assumption of normality was not satisfied. The selection of cultivars ispromising in this arid region of Chile, while the success will depend on the selection of well-adapted genotypesto a particular location.

Abstract: Tree survival, early fruit production, vegetative growth and alternate bearing were examined in six different olive cultivars (Barnea, Biancolilla, Coratina, Empeltre, Koroneiki and Leccino) under intensive agronomic conditions i southern Atacama Desert, in the Coquimbo Region of Chile. The cultivars were evaluated over four successive years and had a high survival rate (93%) confi rming their potential for these dry-lands. Fruit production (recorded over the growing seasons 2002-2003), vegetative growth (2000-2003) and alternate bearing differed signifi cantly among cultivars. Olive selection in intensively managed planting at the southern part of the Atacama Desert depends on matching specifi c cultivars to sites on which they perform the best.
