Abstract: The Field Education movement emerged in the Brazilian society in the last two decades, bringing to the national political scenario the role of social and trade union movements of the countryside in the affirmation and struggle in defense of a new paradigm of education and school for people living and working in the countryside—farmers, camping and agrarian reform settlers, rural workers, indians, quilombolas, among others. Parallel to the achievements of this movement, especially in the context of State public policies for countryside people, the subject of Field Education has gradually been consolidated in national academic productions. However, despite the increasing volume of work and scientific publications in the area, a balance of academic production reveals the existence of a theoretical gap Youth and Adult Education (EJA) in the field. This recognition of the reality of Youth and Adult Field Education in our society is an area yet to be mapped, and considering the existence of a range of practices and dispersed EJA experiences present in the everyday of the countryside that require more specific studies, the research program entitled Practices in Youth and Adult Education, Literacy and Educational Alternations emerged, whose purpose was to carry out a coordinated study network that would enable the systematic collection and production of data and analysis on the EJA experiences present in the rural reality of Brazil, emphasizing the dimensions of educational practices, processes and pedagogical dynamics constructed within these experiences. In this article, originated from this research program, our purposes are to characterize and analyze under the Field Education movement, the EJA experience in the field, called Agrarian Residency Program in its history, principles and political and pedagogical practices, highlighting the alternated training dynamics gestated in its inside and the social representations built by educators on the alternation. Among other aspects, the study results show that the Agrarian Residence Program, as an experience of Youth and Adult Field Education has become a transformation-propellant space in training professionals of Agricultural Sciences, highlighting both the construction of emancipatory pedagogical practices, and the new political and social relations between universities and social movements. In this respect, besides the processes of dialogical and collective training, the Agrarian Residence Program has also provided the students and educators with a set of experiences and reflections on the reality of

Polyoma BK virus: an emerging opportunistic infectious agent of the human central nervous system
Silva, Rodrigo Lopes da;
Brazilian Journal of Infectious Diseases , 2011, DOI: 10.1590/S1413-86702011000300017
Abstract: bk virus, a double-stranded dna virus, is a member of the polyomaviridae family which is known to infect humans. clinical evidence of disease is mostly encountered in immunosuppressed individuals such as aids patients or those who undergo renal or bone marrow transplantation where complications associated with bkv infection manifest commonly as a polyomavirus nephropathy or hemorrhagic cystitis, respectively. recent evidence suggests that in addition to the jc virus (the other member of the same family known to be strongly neurotropic and responsible for the progressive multifocal leukoencephalopathy), bk virus can infect and cause clinically relevant disease in the human central nervous system. in this mini-review, an analysis of the literature is made. a special focus is given to alert clinicians to the possibility of this association during the differential diagnosis of infections of the central nervous system in the immunocompromised host.

Lopes, Cleber da Silva;
Revista de Sociologia e Política , 2011, DOI: 10.1590/S0104-44782011000300008
Abstract: the emergence of private security guards and organizations that supply informal policing poses new problems for civil rights in brazilian society. this paper analyzes state control over private security, through a focus on federal police activity during the 1996 -2000 period. taking the way this control is dealt with in other countries as a crucial reference and using analysis of legal documents as well as interviews with those who are directly involved in the control of private security, we examine the following phenomena: the legal instruments that the federal police has at its disposal for the control of private security; the mechanisms that encourage internal and external control over private security and the watch that is kept over private security and other organizations and agents which engage in informal forms of policing.

Letras de Hoje , 2010,
Abstract: O presente trabalho trata do uso do ciberespa o no ensino da literatura, seja em nível escolar médio ou universitário. Para tanto, apresentamos o relato de duas experiências realizadas com blogs em três turmas do curso de Letras da Universidade Estadual de Maringá nas disciplinas de “Literatura Brasileira: Poesia” e “Tópicos Especiais de Literatura Brasileira”. Após o relato destas experiências, apontado os critérios de avalia o, a metodologia e os resultados, passamos a considerar o uso de chats na realiza o de oficinas on-line de cria o literária. Os resultados da experiência pedagógica realizada com os blogs apresentam-se bastante satisfatórios, pois – de modo geral – seu uso revelou-se uma estratégia muito positiva para fazer com que os alunos produzam mais e diversos tipos de textos, interajam mais com os conteúdos, os colegas e o professor, deixando de serem passivos na rela o professor-aluno, e passem a vivenciar o conhecimento como algo dinamico, percebendo sua produ o como processo. Para encerrar, apresentamos dicas de sites e revistas literárias e culturais on-line que podem ser utilizadas pelos alunos e professores de literatura.

CURRíCULO E A ES AFIRMATIVAS: perspectivas multiculturais
Theoffillo da Silva Lopes
Revista Espa？o do Currículo , 2011,
Abstract: Entendendo que a educa o n o é neutra, e que, por si só, n o tem a capacidade de encarar os problemas sociais existentes sem a tomada de uma posi o positiva e afirmativa por parte dos agentes envolvidos na constru o do currículo, já que este, por sua vez, tem um caráter político, social e de rela es de poder, percebe-se a influência que o mesmo pode ter ou efetuar sobre as políticas e os processos educativos, agindo como reprodutores ou transformadores da realidade. As a es afirmativas para adentro dos muros da educa o formal se tornam inviáveis se, em suas dimens es, os processos educacionais n o forem estabelecidos em currículos com perspectivas multiculturais. Assim, percebe-se que, as perspectivas curriculares multiculturais trazem para as a es afirmativas, a possibilidade de concretiza o dos seus objetivos, além do fato de n o só legitimar o acesso de minorias de grupos, como também ratificar e favorecer a permanência e o auxílio a tais minorias.
