On-line focus group: uma possibilidade para a pesquisa qualitativa em administra??o
Schreder, 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.

Revista de Administra??o IMED - RAIMED , 2011,
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.
Lymphocyte subpopulations during cytomegalovirus disease in renal transplant recipients
Castro S.M.,Sporleder H.,Schreder R.,Santos A.
Brazilian Journal of Medical and Biological Research , 2003,
Abstract: We have determined the number of circulating T, B and natural killer cells in renal transplant recipients in order to detect changes during cytomegalovirus (CMV) infections. Serial blood samples were taken from 61 patients on standard triple immunosuppression therapy (cyclosporin A, azathioprine and prednisone). Using two-color flow cytometry analysis, the absolute number of CD3+, CD4+, CD8+, CD19+, CD3+HLA-DR+ and CD16+56+ cells was determined. Forty-eight patients (78.7%) developed active CMV infection, and all of them subsequently recovered. Twenty of the infected patients (32.8%) presented symptoms compatible with CMV disease during the infectious process. The number of lymphocytes and their main subpopulations were normal before the onset of CMV disease. During the disease there was a decrease followed by a significant increase (P<0.005) in the number of CD3+, CD4+, CD8+ and CD3+HLA-DR+ cells. No significant changes were observed in natural killer cells or B lymphocytes during the disease. We conclude, as observed in all viremic patients recovering from infection, that recovery is associated with an increase in the number of T cell subsets. The monitoring of different lymphocyte subsets along with antigenemia can be extremely useful in the detection of patients at high risk of developing CMV symptoms, allowing the early introduction of antiviral therapy or the reduction of immunosuppression therapy.

Abstract: the best strategy for control of cytomegalovirus (cmv) infection in lung transplant patients is still not determined. the aim of this study was to document the incidence of cmv infection in a cohort of lung transplant recipients under universal prophylaxis with intravenous ganciclovir. all patients received immunosuppressive regimens consisting of cyclosporine, azathioprine, and prednisone. regardless of cmv serostatus, intravenous ganciclovir was prescribed for every patient in the first 3 months post-transplantation. cmv infection was defined as the detection of cmv pp65 in leukocytes. eighty-two lung transplant patients were included over a 5-year period. the incidence of cmv infection in the first year post-transplantation was 68.3%, occurring after a median length of 114 days (range, 26-343 days). this study revealed a high incidence of cmv infection in the first year following lung transplantation despite prolonged universal ganciclovir prophylaxis.

The Position of Mineral Nitrogen Fertilizer in Efficient Use of Nitrogen and Land: A Review  [PDF]
Jaap Jan Schr?der
Natural Resources (NR) , 2014, DOI: 10.4236/nr.2014.515080
Abstract: Our attitude towards mineral nitrogen (N) fertilizers is ambivalent. N fertilizers have on one hand increased our supply of food, feed and other bio-based raw materials tremendously and also improved the use efficiency of land and labor, but have on the other hand a negative impact on the quality of the environment and contributed to the depletion of fossil fuel reserves. This awareness has resulted in strong pleas to spend much more attention to the recycling of N containing downstream “wastes”. It is, however, naive to assume that even perfect recycling suffices to offer the same number of people the same diet without inputs of “new” N, as inevitable losses of N make compensations indispensable. “New” N can be derived from either biological N fixation (“legumes”) or from industrially fixed N (“fertilizer”). The existing literature provides no evidence that the use of N fertilizers is per se unsustainable, as these fertilizers can also be made from renewable forms of energy. Besides, soil health and human health appear sensitive for the dosage but not for the form of N. It is yet imperative to reduce the input of “new” N as much as possible, so as to minimize adverse environmental effects. Measures to this end are a more precise assessment of crop N requirements, a better timing and positioning of N inputs, and any measure supporting the acceptance of “wastes” by farmers. The present paper elaborates the above aspects.

Abstract: learning is not the same as cultural evolution. social learning does not change the world but provides the elements for changing it. it promotes an increase in variation, enlarging the scope of possibilities for evolution.
Identidades coletivas e mobiliza??o de identidades
Eder, Klaus;
Revista Brasileira de Ciências Sociais , 2003, DOI: 10.1590/S0102-69092003000300001
Abstract: contemporary nation states have to reproduce collective identities in societies with increasing ethnic differences. this is the situation where the political order is decoupled from the community of people. the following questions arise in such a situation: what happens to the sentiments of national belonging? how do collective identities decoupled from the nation-state look like? do they still refer to a community below or above the nation-state or does emerge a more abstract or a more instrumental kind of togetherness? what happens to political mobilization in such culturally diversified societies? the final question: do we still need the nation-state for taming collective sentiments or do we have to imagine different forms which require new theoretical tools to describe and design institutions for taming collective sentiments?
