The objective of this study was to validate an electronic system for monitoring individual feeding behavior and feed intake (Intergado Ltd., Contagem, Minas Gerais, Brazil) in freestall-housed dairy cattle. No data have been published that validate either the behavioral measurement or the feed intake of this system. Feeding behavior data were recorded for 12 Holstein cows over 5d using an Intergado system and time-lapse video. The cows were fitted with an ear tag containing a unique passive transponder and provided free access to 12 feed bins. The system documented the visit duration and feed intake by recording the animal identification number, bin number, initial and final times, and the difference between feed weight at start and end of each feed bin visit. These data were exported to Intergado web software and reports were generated. Electronic data on animal behavior were compared with video data collected during the same evaluation period. An external scale was used to manually measure and validate the electronic system's ability to monitor dairy cow feed intake for each feed bin visit. The feed intake was manually measured for 4-h time periods and compared with the sum of the feed intake recorded by the monitoring system for each cow visit during the same time period. Video and manual weight data were regressed on the electronic feeding behavior and feeding intake data to evaluate the precision of the monitoring system. The Intergado system presented high values for specificity (99.9%) and sensitivity (99.6%) for cow detection. The visit duration and feed intake per visit collected using the electronic monitoring system were similar to the video and manual weighing data, respectively. The difference between the feed intake measured manually and the sum of the electronically recorded feed intake was less than 250g (25,635±2,428 and 25,391±2,428g estimated using manual weighing and the electronic system, respectively). In conclusion, the Intergado system is a reasonable tool to monitor feeding behavior and feed intake for freestall-housed dairy cows.

ResumoO estudo da colaboração científica permite observar resultados que podem orientar a gestão da pesquisa em uma organização. Nesse sentido, o objetivo deste estudo é analisar a rede de colaboração científica em nanotecnologia na Empresa Brasileira de Pesquisa Agropecuária e sua evolução, considerando-se ser um tema que vem gerando resultados inovadores para o agronegócio brasileiro. Para tanto, foi empregada a metodologia de Análise de Redes Sociais, com o objetivo de perceber as relações de coautoria e de como analisar a evolução dessa rede de colaboração. Para trabalhar a perspectiva dos dados, foi escolhida a Base de Dados da Pesquisa Agropecuária, de acesso público, organizada e gerenciada pela Embrapa. 2008, 2009 to 2011, and 2012 to 2014. The results showed that the data represents a significant timeframe for analysis, nearly 10 years, providing the perception that, insofar as the evolution of the network is concerned, it evidently occurred in a gradual manner, highlighting the fact that scientific collaboration in nanotechnology at Embrapa becomes increasingly effective and dynamic. Abstract The study of scientific collaboration allows us to observe, for instance, results that can guide research management in an organization. In this sense, the objective of this study is to analyze the network for scientific collaboration in nanotechnology at the Brazilian Agricultural Research Corporation, and the evolution thereof, since this is a field which has produced innovative results for Brazilian agribusiness. To this end, the methodology of Social Network Analysis was used in order to identify co-authorship connections and to analyze the evolution of this network. The origin of the data was Agricultural Research Database

A premissa central deste artigo – parte de uma pesquisa de mestrado – é a verificação do entendimento sobre o conceito e prática de gestão do conhecimento na administração pública federal, onde foram selecionados e entrevistados nove gestores de organizações públicas federais em Brasília. Os resultados mostraram que a gestão do conhecimento organizacional, de acordo com o ponto de vista dos gestores públicos entrevistados, não é como conceito, uma idéia nova, mas um processo incipiente, cujo escopo, inserido no campo da cognição humana, apenas começa a ser discutido com mais profundidade na esfera da administração pública neste limiar do século XXI. Verificou-se, quando da aplicação das entrevistas, no ano de 2003, que nessas organizações públicas existe um significativo investimento nas áreas tecnológica e estratégica em detrimento dos investimentos nas áreas de capacitação e desenvolvimento de recursos humanos, que se constituem, na literatura revisada, como a essência da gestão do conhecimento.
