Work and technological innovation in organic agriculture

Organic agriculture is a sustainable cultivation ecologically, economically and socially. Several researches in organic agriculture have been made from technical perspectives, economic traits or related to ecological aspects. There are practically no investigations into the nature of the technology used in organic agriculture, especially from an ergonomic perspective. From the activity analysis, this study aimed to map the technology used in the production of organic vegetables. Properties producing organic vegetables were selected representing the State of São Paulo. It was applied an instrument (questionnaire and semi-structured interview) with their managers and it was made visual records to identify adaptations, innovations and technological demands that simultaneously minimize the workload and the difficulties in performing the tasks and increase work productivity. For some of the technological innovations a digital scanner was used to generate a virtual solid model to facilitate its redesign and virtual prototyping. The main results show that organic farmers have little technology in product form. The main innovations that enable competitive advantage or allow higher labor productivity occur in the form of processes, organization and marketing.

Foraging, diet and community structure in an epigaeic ant (Hymenoptera: Formicidae) assemblage: the role of recruitment

The significance of recruitment systems for community structure of epigaeic ants in a tropical upland forest in southern Brazil was evaluated by examining patterns of spatial occurrence at fixed points. Normal exploratory activity was evaluated with pitfall traps, while the effect of recruitment and diet was evaluated by using honey and sardine baits at the same points. Through techniques developed for environmental impact assessment, the significance of recruitment was evaluated following perturbation, or the placement of bait. Of the 46 species encountered, 15 were sufficiently frequent to study. Of these, only 6 showed significant spatial frequency changes at baits when compared with pitfall trap collections. In one analysis, monthly differences were important for a few smaller species, suggesting thermic limitations, while bait types either increased or decreased spatial point usage. The magnitude of spatial point variation is an index for the strength of recruitment in community organization. Bait types suggest nutritional possibilities of each species. Both recruitment and diet are probably functions of the species composition of the ant community.

Serviço de Referência Virtual: implantação do serviço de chat

Introduction: With the invention of the Internet and the Collaborative Web, libraries had to rethink the way to offer their services. Thus, the U.S. libraries began a search for technological innovations in an effort to bring the library to the user through features that patrons commonly use. The Virtual Reference Service (VRS) through chat and reference services via videoconferencing are features that derived from this search. Objective: This article aims to outline the implementation process of Virtual Reference Services (SRV) libraries in American universities, particularly those for chat, as well as presenting the successful Brazilian experience. This paper also discusses factors to be considered for implementing virtual reference service via chat for libraries wishing to offer the service. Methodology: The research methodology is based on a theoretical search on international and national literature on the subject. The methodology also includes participant observation. Results: In Brazil the implementation of SRV in some university libraries has occurred and according to these institutions, the SRV is a service that benefits the community and puts the library in line with the demands of information technology and communication. Conclusions: It is concluded that online SRV is appropriate to the reality of university libraries in Brazil, since the institutions that offer the service have positive results from their assessments and believe they are adding value to their library.

Inovações tecnológicas na caprinocultura

O largo crescimento do setor de agronegócios no Brasil tem estimulado mudanças nos sistemas produtivos, tanto na intensificação, como na profissionalização da produção. Dessa forma, os produtores têm buscado estratégias para melhor atender aos desafios da atividade pecuária atual, dentre as quais se destacam as inovações tecnológicas que devem resultar em comprovado benefício à atividade, seja pelo aumento em produtividade, seja pela melhoria na qualidade dos produtos, seja pela conscientização do respeito ao meio ambiente. Assim como em outros segmentos do agronegócio brasileiro, na caprinocultura existe uma demanda crescente pela aplicação de inovações tecnológicas, uma vez que o sistema produtivo precisa ser mais competitivo para se manter no mercado. Dentre as inovações tecnológicas aplicadas na caprinocultura, foram abordadas as mais relevantes nas áreas de reprodução (desde métodos para indução de cio até a prática da transgenia), melhoramento genético (biogenética), sanidade (inovações no diagnóstico e prevenção de doenças de maior impacto na criação), nutrição (inovações nos sistemas de alimentação) e tratamento de dejetos (diminuição de contaminantes no ambiente). A utilização conjunta das inovações tecnológicas nos diferentes segmentos associados à cadeia produtiva caprina pode fazer com que ocorram melhorias nos rebanhos assim como nos produtos gerados.

Factors determining the structure of fish communities in Pantanal lagoons (MS, Brazil)

The fish communities of lagoons in the Nhecolandia Pantanal were studied to determine the factors which are responsible for the composition and abundance of species. Fishes were collected in 19 lagoons during August 1997, after their isolation from the River Negro, using beach seines (15 x 1.5 m; 2 mm mesh). A total of 51 species were collected. In the lagoons, or in parts with dense macrophytes, a screened box trap was used. Fishing was also accomplished with hooks of several sizes. Species richness was estimated by the jack-knife procedure, after adjustment to the log-normal distribution and with von Bertalanffy's equation (asymptotic). The most important factors in the community organization were macrophyte cover, piscivore abundance and depth of the lagoons. The role of these habitats in the Pantanal ecosystem was discussed.

Manejo de irrigação e nitrogênio no feijoeiro comum cultivado em sistema plantio direto

With technological innovations, such as irrigation, the bean has been grown by producers who have the most varied levels of technology that, in suitable times, allows the planting great success in grain yield. The aim of this study was to evaluate the response of the dry bean to different managements of irrigation and nitrogen fertilization with no-tillage system, in Aquidauana - MS, Brazil. The experiment was conducted at the Universidade Estadual de Mato Grosso do Sul (UEMS), with the soil of the area classified as Alfisol, using the bean crop "Perola" sown on June 30, 2007. The experimental design was a randomized block split-plot consisting of three blocks and two replications within each block. The plots were composed of three management of irrigation, by the Class A pan method, using Hargreaves-Samani equation, and management by tensiometry (-40 kPa), with water replacement of 16.5 mm for all irrigation plots. The subplots consisted on four rates of nitrogen fertilization (0; 50; 100 and 150 kg ha(-1)), in which the nitrogen source was urea. It was concluded that the irrigation management through the Class A pan and Hargreaves-Samani equation conduced to higher grain yields of bean, 3031.11 and 3005.02 kg ha(-1) respectively.

RESTRUCTURING of SYSTEMS and LOGISTICS of MOVEMENT and ITS IMPACT on URBAN and REGIONAL PLANNING PAULISTA

Report some of the changes in production and consumption occurring in the state of São Paulo. through the restructuring in motion systems, logistics and standards and taxation, as well as the impacts on urban spaces through new economic dynamics, imposed by the demands of corporate, is the purpose of this article. The decentralization of production and consumption towards the interior was made possible by the combination of hierarchical and ordered some basic elements such as technological innovations (ways and means of transport) and organizational (logistics, standards and taxation) which optimized the flow territorial state São Paulo. It is noteworthy, therefore: 1) the improvement of logistics as a strategy, planning and management of transport, storage and communications (including the granting of public services to private), 2) the technological improvement and expansion of motion systems (infrastructure, means of transport) and 3) the systems of rules and regulations through taxation and deregulation affect the circulatory system of a given space. Thus, both systems aims to disentangle the economic flows (goods, services, information, capital and people) and provide a more fluid territorial. The impacts on the State of São Paulo, mainly through its economic dynamics, revert positively and negatively, by changing the way one thinks and performs planning.
