Inter-And Transdisciplinary Action-Formation-Research with People Involved in the Homeless Issue

Este artigo apresenta reflexões teórico-metodológicas sobre processo de investigação de pós-doutorado que objetivava basicamente construir - na ação - estratégia de "psico-sócio-formação" de pessoas envolvidas com a questão do morador de rua; criar e aplicar um recurso metodológico operacional denominado "conto de encontro transformador". Do ponto de vista teórico, sob perspectivas inter e transdisciplinares de produção do conhecimento, essa "pesquisa-ação-formação" baseou-se no encontro dialógico entre os conhecimentos sobre "encontro transformador", "resiliência" e "ágape" e construtos teóricos da área da Educação, com ênfase no processo de autoformação. O projeto contou com vinte participantes: moradores de rua; trabalhadores de instituições de apoio a moradores de rua; técnicos das Secretarias de Assistência Social da Prefeitura de São Paulo e/ou da Secretaria da Saúde; e provenientes da Universidade de São Paulo e de outras Universidades do Brasil, França e Canadá.This paper presents theoretical and methodological reflections on a postdoctoral investigation process that aimed to build - on action - a psychological, social and formational strategy targeted at people involved in the question of homeless individuals; and to create and apply an operational methodological resource called "transforming encounter short story". From the theoretical point of view, under inter- and transdisciplinary perspectives of knowledge production, this action-formation-research was based on the dialogic encounter between the concepts of "transforming encounter", "resilience" and "agape"; and on theoretical constructs from the Education area, with emphasis on the self-formation process. The project had twenty participants: homeless people; workers from institutions that support the homeless; technicians with the Social Work Departments of the Municipal Government of São Paulo and/or with the Health Department; and participants from the University of São Paulo and from other Universities of Brazil, France and Canada

Towards the solution of the CP/CAC_{P}/C_{A} anomaly in shell-model calculations of muon capture

Recently many authors have performed shell-model calculations of nuclear matrix elements determining the rates of the ordinary muon capture in light nuclei. These calculations have employed well-tested effective interactions in large scale shell-model studies. For one of the nuclei of interest, namely $^{28}$Si, there exists recent experimental data which can be used to deduce the value of the ratio $C_{P}/C_{A}$ by using the calculated matrix elements. Surprisingly enough, all the abovementioned shell-model results suggest a very small value ($\simeq 0$) for $C_{P}/C_{A}$, quite far from the PCAC prediction and recent data on muon capture in hydrogen. We show that this rather disturbing anomaly is solved by employing effective transition operators. This finding is also very important in studies of the scalar coupling of the weak charged current of leptons and hadrons.Comment: Revtex, 6 pages, 2 figs include

Shell Model Monte Carlo studies of neutron-rich nuclei in the 1s-0d-1p-0f shells

We demonstrate the feasibility of realistic Shell-Model Monte Carlo (SMMC) calculations spanning multiple major shells, using a realistic interaction whose bad saturation and shell properties have been corrected by a newly developed general prescription. Particular attention is paid to the approximate restoration of translational invariance. The model space consists of the full sd-pf shells. We include in the study some well-known T=0 nuclei and several unstable neutron-rich ones around N=20,28. The results indicate that SMMC can reproduce binding energies, B(E2) transitions, and other observables with an interaction that is practically parameter free. Some interesting insight is gained on the nature of deep correlations. The validity of previous studies is confirmed.Comment: 22 pages + 7 postscript figure

Production of Osteopontin by Cultured Porcine Epithelial Cell Rests of Malassez

Background:  The epithelial cell rests of Malassez (ERM) are derived from Hertwig's epithelial root sheath (HERS). During development the cells of HERS deposit a variety of molecules on the newly forming root surface. The possibility that ERM retain this potential after root development is completed and secrete bone or cementum-related proteins needs to be investigated. The purpose of this study was to determine the expression of the non-collagenous proteins osteopontin (OPN) and bone sialoprotein (BSP) by cells derived from the epithelial cell rests of porcine periodontium. Methods:  ERM and fibroblasts were cultured from porcine periodontal ligament. The cells were identified and characterized using transmission electron microscopy, immunohistochemistry, western blot analysis of proteins, reverse transcription–polymerase chain reaction and ability to form mineralized nodules in culture. In particular the expression of the mineralized tissue-related proteins, BSP and OPN, was studied. Results:  Cells from porcine periodontal ligaments were successfully cultured; separated and characterized as being of either an epithelial or fibroblastic phenotype. Although the ERM did not form mineralized nodules in culture, they did express a significant amount of mRNA for OPN. Conclusion:  The results from this study provide evidence that ERM express mRNA for at least one bone/cementum-related protein. Whether this function would be consistent with a role for ERM in tissue formation, inflammation and regeneration remains to be established
