Gestão do conhecimento científico: proposta de um modelo para a área de Ciência da Informação da Universidade Estadual Paulista (Unesp)

Universities produce large volume of scientific knowledge; however, much of this knowledge is not properly systematic and socialized, causing losses to the development of Science and society. Therefore, there is the need to apply methods, techniques and tools that facilitate the systematization and sharing the knowledge generated in this context. In this perspective, a study aimed at developing a model of the knowledge management representing the specific area of Information Science (IS) of the Sao Paulo State University [Universidade Estadual Paulista (UNESP)]. For this, a qualitative study was developed, descriptive and exploratory, consisting in five steps: started with the theoretical foundation about the thematic, defined the appropriate methodology, comprising characterization of the area of CI Unesp; collecting and analysis of information about the generation, socialization, ownership and communication of scientific knowledge in this environment. As a result of the study, it was possible to develop a model of scientific knowledge management. This model represents the elements involved in the dynamics of scientific knowledge, serving as a starting point for the planning and execution of future actions for the management of scientific knowledge. The study also presents an initial diagnosis on the state of art of scientific knowledge in the academic community of CI from Unesp.

Retextualização da escrita por alunos com surdez usuários da LIBRAS: em foco a mediação do professor

The way teachers will coordinate the writing appropriation process assumes an especial importance, sharing their knowledge with the deaf student, assigning importance and meaning for what this student was capable to produce, even if his production isn’t resembled to the idealized pattern of an adult writing. This study is proposed to investigate the mediation in rewriting activities, along with deaf students, held by eight trainee students of a Pedagogy course, with ages between 20 and 28 years old. Thereunto, this activities were recorded on video, for later transcription and descriptive analysis, subsided by a new model proposed in the literature. The results indicate: the importance of the rewriting in the understanding of write contents produce by deaf students, the participants’ attitudinal change about their role like coordinator and interlocutor in such activities and the greater teacher’s comprehension about notational and discursive aspects involved in the deaf student write production. These results allowed to conclude the future teachers’ need that will work in inclusive classes or in multifunctional classes, understand and use rewriting activities in their daily pedagogical practice for the appropriation for the promotion of the Portuguese write by the deaf student, user of LIBRAS. It should be noted these teachers’ need to know the LIBRAS’ grammar and have access to linguistic knowledge enabling them to comprehend the nature of the occurrences present in the texts produced by deaf students.

Production of β-(1,3)-glucanases by Trichoderma harzianum Rifai: Optimization and Application to Produce Gluco-oligosaccharides from Paramylon and Pustulan

β-(1→3)-Glucanases were produced by Trichoderma harzianum Rifai PAMB-86 cultivated on botryosphaeran in a bench-fermenter and optimised by the response surface method. Maximal enzyme titres occurred at 5 days, initial pH 5.5 and aeration of 1.5vvm. β-(1→3)-The β-glucanolytic enzyme complex produced by T. harzianum Rifai PAMB- 86 was fractionated by gel filtration into 2 fractions (F-I, F-II), and employed to produce gluco-oligosaccharides from algal paramylon ((1→3)-β-D-glucan) and lichen pustulan ((1→6)-β-D-glucan). Both enzymes attacked paramylon to the extent of ~15-20% in 30 min releasing glucose and laminaribiose as major end-products, and laminarioligosaccharides of degree of polymerization (DP) ≥3. Only F-I degraded pustulan resulting in ~2% degradation at 30 min, with glucose, gentiobiose and gentio-oligosaccharides of DP ≥4 as major products. The difference in the nature of the hydrolysis products can be explained by the substrate specificities of each enzyme fraction, and the structural differences of the β-D-glucans attacked.

Social networks on the Internet: a practical investigation about file sharing on Facebook

The social networks on the internet have experienced rapid growth and joined millions of users in Brazil and throughout the world. Such networks allow groups of people to communicate and exchange information. Sharing information in files is also a growing activity on the internet and is done in various ways. However, applications are not yet available to enable file sharing on Facebook, the premier social network today. This study aims to investigate how users use Facebook, and their practices for file sharing. Due to the experimental nature of this research, we opted for a data collection survey, applied over the web. From the data analysis, we have found a frequent use of file sharing, but no interest in paid services. As for Facebook, there was an extensive use of applications. The set of results shows a favourable scenario for applications that allow file sharing on Facebook.

Influência do ambiente no desenvolvimento de colônias iniciais de formigas cortadeiras (Atta sexdens rubropilosa)

Annually, mature colonies of Atta ants produce winged males and females, where leave the colony in which they were produced to form new colonies and thus continue the species perpetuation. The foundation of Atta spp. colonies always involves high queen effort, solely responsible for growing the fungus and the care with itself and its offspring. During the foundation there is consumption of body reserves. This study investigated how the environment influences the development of newly founded colonies of leaf cutting ant, Atta sexdens rubropilosa. Therefore, it was compared field colonies collected five months after the nuptial flight and colonies maintained in the laboratory since the nuptial flight. It was analyzed the weight and size of the population (number of workers, larvae, pupae and eggs), the workers size, the volume and weight of the fungus garden and queen effort for the nest foundation (lipid content and weight of queens). In comparison to the field colonies, the laboratory colonies showed higher values in the weight and size of population, the volume and weight of the fungus garden. Measures of workers by class size did not vary between colonies from field and laboratory. The queen effort for nest foundation was higher in field colonies, which showed a lower percentage of fat and lower weight compared to laboratory colonies. These results show that the environment has a strong influence on the colonies development during the foundation, as well as on the physiological status of the queens, and therefore the survival, development and success of the colony, it is a reflection of the queen efforts and of the environment conditions.
