On-line focus group: uma possibilidade para a pesquisa qualitativa em administra??o
Schr?eder, Christine da Silva;Klerin, Luis Roque;
Cadernos EBAPE.BR , 2009, DOI: 10.1590/S1679-39512009000200010
Abstract: the use of focal groups (focus groups) as a technique of research represents an interesting alternative to the development of qualitative studies. normally, this technique involves the participation of 6 to 10 respondents which discuss specific topics about some subject, and the interaction that occurs between the members of the group is also considered an important data. also, while it considers the influence of the technologies of information, specially the internet, the technique can still be applied virtually - through on-line focus groups (ofgs) -, through the use of tools like e-mail, chats and lists of discussion. based on the analysis of brazilian academic research in the business area, it was observed that the use of focus group is still incipient, especially in its on-line form. thus, the present paper aims to characterize ofgs and how it can be conducted, as well as to describe the advantages and disadvantages that result from its apllication, and suggesting its use in qualitative research in administration.

Abstract: With growing options of Information and Communication Technologies (ICTs) on the Internet, there is a growing interest in using them to improve, expand and facilitate educational processes, be it in face-to-face learning or distance learning. In order to integrate multiple media, software and resources, facilitate interactions between teachers and students, as well as between people and objects of knowledge, within the environment of the Internet, different processing system solutions have been developed, especially since 1990, in the form of Learning Management Systems (LMS). Some examples of LMS include: MOODLE, TelEduc and Blackboard. The high levels of interest in researching and building LMS usually stems from areas such as Education, Information Technology and Communication. However, this article presents the unique and innovative aspects of the LMS NAVI, Interactive Learning Environment that was developed in Brazil at the UFRGS School of Business Administration by a core of researchers and technicians from different backgrounds, but especially from the field of Administration. The constructed virtual environment brings in tow the influences of concepts derived from Management theory, especially Systems Theory. It differs from LMSs, which are known for the systemic approach of their organizational structures (and navigation), rather than the traditional linear and mechanistic approach. For this reason, it has more advanced properties, especially in terms of adaptability, flexibility, recursion and multidimensionality, as opposed to the rigidity, linearity, specificity and onedimensionality of traditional learning platforms. Due to its innovative character, the platform has received growing academic and professional support, and it is believed that it could constitute a genuine and innovative educational, conceptual and technological solution in the Brazilian context.

Abstract: we present the patterns of organization that emerge from the developmental process of mother-infant communication in face-to-face exchanges. this process is conceived as creating a dynamic system in constant transformation and construction. the patterns of organization describe the periods of stability of this system, proposed by the eea model as corresponding to three successive patterns, starting by an initial establishment, followed by a period of extension, and finally by an abbreviation of the dyadic exchanges. we analyzed the longitudinal mother-infant face-to-face exchanges from five dyads, describing the process of organization of these patterns. we identified a general tendency toward maintenance of the sequence of emergence and dominance of these three patterns in all five dyads, according to the proposals of the eea model. however, each dyad differs in terms of age of appearance, dominance and duration of each of these patterns.

Abstract: O conhecimento adquirido ao longo dos tempos levou o homem a deixar de ser n made, evoluindo processos relacionados à agricultura e pecuária e, com isso, descobriu que poderia cultivar seus alimentos e domesticar os animais, n o precisando mudar de um lugar para outro para garantir sua sobrevivência. Porém, naquela época, n o foi possível documentar o conhecimento que haviam adquirido e a tecnologia que desenvolveram. Gra as ao conhecimento adquirido pelo homem ao longo dos tempos, temos avan adas tecnologias que nos proporcionam melhor qualidade de vida e de trabalho. A sociedade contemporanea está se caracterizando pela velocidade que as mudan as est o ocorrendo no ambiente, ocasionadas pela globaliza o e pelo fácil acesso a informa o, o que vem gerando constantemente novos conhecimentos. As organiza es dessa nova sociedade devem estar preparadas para essas constantes mudan as, para que assim se mantenham competitivas e possam se perpetuar no mercado. à respeito disto, a gest o do conhecimento ganhou notoriedade nas discuss es acadêmicas e organizacionais devido à relevancia do assunto como forma de transformá-lo em fatores competitivos. Desta forma, o presente artigo pretende apresentar e discutir as teorias e ferramentas pertinentes à cria o, dissemina o e utiliza o dos inúmeros conhecimentos gerados pelas pessoas nas organiza es. Este estudo justifica-se pela temática contemporanea e ainda em fase de desenvolvimento e da importancia do referido no cenário globalizado e competitivo. A metodologia utilizada foi de caráter bibliográfico e as perspectivas geradas pela discuss o giram em torno das ferramentas existentes para a cria o e dissemina o do conhecimento organizacional como a universidade corporativa ou a simples ado o de reuni es expositivas para a gera o de idéias voltadas ao cenário das organiza es. Além destas, as organiza es podem utilizar sistemas complexos de informa o, redes sociais relacionadas à práticas e educa o corporativa continuada. As organiza es já se deram conta que a Gest o do Conhecimento Corporativo n o pode ser vista como modismo gerencial, pois o conhecimento corporativo deve ser tratado como um bem valioso para a perpetuidade das organiza es.

Abstract: Background The laboratory diagnosis of Chagas disease is challenging because the usefulness of different diagnostic tests will depend on the stage of the disease. Serology is the preferred method for patients in the chronic phase, whereas PCR can be successfully used to diagnose acute and congenital cases. Here we present data using a combination of three TaqMan PCR assays to detect T. cruzi DNA in clinical specimens. Methods/Principal Findings Included in the analysis were DNA extracted from 320 EDTA blood specimens, 18 heart tissue specimens, 6 umbilical cord blood specimens, 2 skin tissue specimens and 3 CSF specimens. For the blood specimens both whole blood and buffy coat fraction were analyzed. The specimens were from patients living in the USA, with suspected exposure to T. cruzi through organ transplantation, contact with triatomine bugs or laboratory accidents, and from immunosuppressed patients with suspected Chagas disease reactivation. Real-time PCR was successfully used to diagnose acute and Chagas disease reactivation in 20 patients, including one case of organ-transmitted infection and one congenital case. Analysis of buffy coat fractions of EDTA blood led to faster diagnosis in six of these patients compared to whole blood analysis. The three real-time PCR assays produced identical results for 94% of the specimens. The major reason for discrepant results was variable sensitivity among the assays, but two of the real-time PCR assays also produced four false positive results. Conclusions/Significance These data strongly indicate that at least two PCR assays with different performances should be combined to increase the accuracy. This evaluation also highlights the benefit of extracting DNA from the blood specimen's buffy coat to increase the sensitivity of PCR analysis.

Crop Breeding and Applied Biotechnology , 2008,
Abstract: In Brazil, papaya is sustained by a narrow genetic basis, with few genetically distinct cultivars for planting.Therefore, this study aimed to select and estimate the direct and combined genetic gains for commercial fruit yield (Yld Plt-1)in segregating generations of papaya. Six traits were simultaneously targeted in combined selection and were attributedweights associated to agronomic values. Direct selection however was based on Yld Plt-1 only. Results indicated geneticvariability in the segregating generations for the evaluated traits and although combined selection achieved a lower geneticgain in Yld Plt-1, it offers greater chances of success in the following generations since favorable and unfavorable agronomictraits of papaya are considered. These results motivated the recommendation to advance generations with 30 plants, selectedfrom a total of 345 plants, considering all segregating treatments.

Abstract: This study aimed to evaluate the genetic and seasonal influence on sex expression in segregating generationsof papaya elite and backcrossed genotypes. In the four seasons of the 2005/2006 growing season, 200 hermaphrodite plantswere evaluated. Of the eight studied traits, four were related to flowering and four to fruiting, i.e., to the percentage of normal,deformed, sterile, and total number of flowers, as well as the percentage of total, carpelloid, pentandric, and marketablefruits. Significant differences due to the genotype x season interaction were verified. Based on the genotypic determinationcoefficient and the variation index it was concluded that winter and spring are most appropriate for the selection of superiorgenotypes. Thus, selection in early stages of plant development is more successful, indicating that the physiological age mayalso be a factor involved in the expression of the above traits.
