This study reports part of a broader research about information behavior of graduate students in Education. The research´s participants were nine masters and doctoral students from a graduate program in Education at a public university. The focus group technique was used to collect the data. The focus group sessions were observed and recorded. The recorded data were transcribed, categorized and then analyzed using the technique of content analysis. The main aspects achieved were: i) Identification’s forms of information resources for research; ii) Internet as source of information; iii) Academic Library’s services and resources use; iv) Training to use of electronic data base; v) Difficulties to perform the search; vi) Advisor’s influence on research development; and vii) Environmental factors that affect information seeking behavior. The main results reveal that the identification of information sources occurs, mainly, through references quoted on studies of the researched area; as well as the advisors’ influence in the information seeking behavior of the participants. The results, also, disclose some environmental aspects, as example, lack of time to search and discomfort caused by the libraries’ environment that influenced negatively the information behavior of the studied group.

A gestão da informação é extremamente importante para as organizações. O mapeamento informacional é um instrumento que pode ser utilizado no âmbito da gestão da informação. Para realizar o mapeamento informacional, pode-se utilizar o método denominado Infomapping, criado por Burk Jr. e Horton Jr., que se constitui em uma valiosa ferramenta para gerenciar os recursos de informação de uma organização. Ele permite descobrir com exatidão o grau de desconhecimento que se tem sobre as fontes, serviços e sistemas com os quais se desenvolve o trabalho informacional da organização. O processo consiste em criar um levantamento de todas as informações, que supostamente constituem-se num recurso informacional gerado internamente ou produzido externamente, que impactam diretamente as atividades corporativas.

Feedlot consulting nutritionists were invited to participate in a survey of feedlot nutritional and management practices in Brazil. Thirty-one nutritionists completed the survey on a Web site that was designed for collection of survey data. The survey consisted of 94 questions that included general information (n = 10); commodity information (n = 12); and questions about the use of coproducts (n = 5), roughage source and levels (n = 5), finishing diet adaptation methods (n = 7), supplements and micronutrients (n = 8), feed mixers (n = 6), feeding management (n = 3), cattle management and type of cattle fed (n = 16), formulation practices (n = 17), information resources used for nutritional recommendations (n = 2), and 2 additional questions. One final question addressed the primary challenges associated with applying nutritional recommendations in practice. The number of animals serviced yearly by each nutritionist averaged 121,682 (minimum = 2,000; maximum = 1,500,000; mode = 120,000; total = 3,163,750). Twenty-two respondents (71%) worked with feedlots that feed less than 5,000 animals/yr. Labor, along with availability and precision of equipment, seemed to be the main challenges for the nutritionists surveyed. Most of the nutritionists surveyed used TDN as the primary energy unit for formulation. More than 50% of the clients serviced by the 31 nutritionists did not manage feed bunks to control the quantity of feed offered per pen, and 36.6% fed cattle more than 4 times daily. The NRC (1996) and Journal of Animal Science were the most used sources of information by these nutritionists. Overall, general practices and nutritional recommendations provided by the 31 nutritionists surveyed were fairly consistent. Present data should aid in development of new research, future National Research Council models, and recommendations for Brazilian feeding systems in which Bos indicus cattle predominate.

The development of new technologies that use peer-to-peer networks grows every day, with the object to supply the need of sharing information, resources and services of databases around the world. Among them are the peer-to-peer databases that take advantage of peer-to-peer networks to manage distributed knowledge bases, allowing the sharing of information semantically related but syntactically heterogeneous. However, it is a challenge to ensure the efficient search for information without compromising the autonomy of each node and network flexibility, given the structural characteristics of these networks. On the other hand, some studies propose the use of ontology semantics by assigning standardized categorization of information. The main original contribution of this work is the approach of this problem with a proposal for optimization of queries supported by the Ant Colony algorithm and classification though ontologies. The results show that this strategy enables the semantic support to the searches in peer-to-peer databases, aiming to expand the results without compromising network performance. © 2011 IEEE.
