WHY DO WE HAVE SO MANY SOCIAL SECURITY CLAIMS IN BRAZIL?

In his Reading the Landscape of Disputes: What We Know (And Think We Know) about Our Allegedly Litigious Society, Marc Galanter suggests a different reading of the landscape of disputes in the United States, exchanging the "litigation explosion" reading for a more "contextual" approach. Based on some of Galanter's strategies, our paper tries, in its first section, to question the common core, rejecting three of the most commons arguments used to explain the so called "litigation explosion" in Brazil: that Brazilians are too litigious, that our Judiciary is too small and that access to courts is too easy. In the second section, using social security claims as an example, we try to provide a different reading of the causes for so many lawsuits in that area. We argue, although in an exploratory way, that the dispute resolution system for social security claims pretends to use two filters ‒ administrative agency and court-connected mediation ‒ that do not imply fewer lawsuits and, in fact, could act as propellers for more cases to be brought to the Judiciary.Article信州大学経法論集 5(ブラジル・日本国際セミナー特集号) : 91-115(2019)departmental bulletin pape

The Kolmogorov-Riesz compactness theorem

We show that the Arzela-Ascoli theorem and Kolmogorov compactness theorem both are consequences of a simple lemma on compactness in metric spaces. Their relation to Helly's theorem is discussed. The paper contains a detailed discussion on the historical background of the Kolmogorov compactness theorem.Comment: This version is lightly revised in response to referee comments.

Quais saberes são mobilizados para suprir as lacunas na formação inicial referentes à história da ciência?

Nowadays it is increasingly required insertion History of Science on content to be worked in education, which raises many doubts and difficulties on the teachers did not have that content in their initial training. This work results from a qualitative empirical study aimed to investigate how a teacher of Biology and Science in a public school in the city of Bauru, São Paulo state, was not in their initial training courses relating to the History of Science, mobilizes their knowledge to enter such an approach in their teaching practice. In the research methodology used as its theme the history of DNA present in the materials and also conduct open interviews and field notes to identify the knowledge involved in teaching practice and was adopted as the theoretical framework of Maurice Tardif’s Teachers Knowledge. The results showed that even with difficulties arising from gaps in initial training teachers used their experiential knowledge to fill these needs, as well as appropriating knowledge from the programs and textbooks, but their shortcomings make it difficult to analyze more critically. Thus, these data lead us to a reflection on the role of textbooks for these teachers and the process by which the knowledge they construct occurs.Atualmente é cada vez mais exigida à inserção da História das Ciências no conteúdo a ser trabalhado no ensino, o que gera muitas duvidas e dificuldades nos professores que não tiveram esse conteúdo em sua formação inicial. O presente trabalho resultante de um estudo empírico qualitativo objetivou investigar como uma professora, de Biologia e Ciências de uma escola publica do município de Bauru - SP que não teve em sua formação inicial disciplinas referentes à História da Ciência, mobiliza seus saberes para inserir essa abordagem em sua prática docente. Na metodologia da pesquisa utilizamos como tema a história do DNA presente nos materiais didáticos e também realizamos entrevistas abertas e notas de campo para identificar os saberes envolvidos na prática docente, sendo adotado como referencial teórico os Saberes Docentes de Maurice Tardif. Os resultados demonstraram que mesmo com dificuldades provenientes das lacunas da formação inicial, a professora recorreu aos seus saberes experienciais para suprir essas carências além de apropriar-se de saberes provenientes dos programas e livros didáticos, porém suas lacunas dificultam uma analise mais crítica. Assim, esses dados nos conduzem a uma reflexão sobre o papel dos livros didáticos para esses professores e o processo pelo qual ocorre a consolidação dos saberes por eles construído

Disorder effects in diluted ferromagnetic semiconductors

Carrier induced ferromagnetism in diluted III-V semi-conductor is analyzed within a two step approach. First, within a single site CPA formalism, we calculate the element resolved averaged Green's function of the itinerant carrier. Then using a generalized RKKY formula we evaluate the Mn-Mn long-range exchange integrals and the Curie temperature as a function of the exchange parameter, magnetic impurity concentration and carrier density. The effect of the disorder (impurity scattering) appears to play a crucial role. The standard RKKY calculation (no scattering processes), strongly underestimate the Curie temperature and is inappropriate to describe magnetism in diluted magnetic semi-conductors. It is also shown that an antiferromagnetic exchange favors higher Curie temperature.Comment: tex file + 4 .eps figures are included. submited to PR

Disordered Correlated Kondo-lattice model

We propose a self-consistent approximate solution of the disordered Kondo-lattice model (KLM) to get the interconnected electronic and magnetic properties of 'local-moment' systems like diluted ferromagnetic semiconductors. Aiming at $(A_{1-x}M_x)$ compounds, where magnetic (M) and non-magnetic (A) atoms distributed randomly over a crystal lattice, we present a theory which treats the subsystems of itinerant charge carriers and localized magnetic moments in a homologous manner. The coupling between the localized moments due to the itinerant electrons (holes) is treated by a modified RKKY-theory which maps the KLM onto an effective Heisenberg model. The exchange integrals turn out to be functionals of the electronic selfenergy guaranteeing selfconsistency of our theory. The disordered electronic and magnetic moment systems are both treated by CPA-type methods. We discuss in detail the dependencies of the key-terms such as the long range and oscillating effectice exchange integrals, 'the local-moment' magnetization, the electron spin polarization, the Curie temperature as well as the electronic and magnonic quasiparticle densities of states on the concentration $x$ of magnetic ions, the carrier concentration $n$, the exchange coupling $J$, and the temperature. The shape and the effective range of the exchange integrals turn out to be strongly $x$-dependent. The disorder causes anomalies in the spin spectrum especially in the low-dilution regime, which are not observed in the mean field approximation.Comment: Accepted by JMM

DIFICULDADES ENCONTRADAS PELOS DOCENTES DE UMA ESCOLA ESTADUAL LOCALIZADA NO ESTADO DO PARANÁ FRENTE A ALUNOS QUE APRESENTAM DISTÚRBIOS DE APRENDIZAGEM

O presente artigo é referente à parte dos resultados obtidos em uma pesquisa para a finalização da disciplina de Estágio Supervisionado para a Docência no Ensino de Ciências, do curso de Ciências Biológicas em uma Universidade Pública no Estado do Paraná. O trabalho consistiu em apresentar as dificuldades e barreiras encontradas pelos docentes de um colégio estadual, em um município no Estado do Paraná, em relação ao processo de ensino e aprendizagem de alunos que possuem algum distúrbio de aprendizado. Para tanto, apresentamos um breve histórico da educação especial no Brasil e uma descrição de um dos principais problemas de aprendizagem o Transtorno de Déficit de Atenção e Hiperatividade (TDAH). Os resultados foram obtidos mediante a aplicação de questionários entregues a professores do colégio, que responderam a diversas perguntas referentes ao tema. De posse dos resultados, inferimos que os professores tem conhecimento restrito na área dos distúrbios de aprendizagem e têm dificuldades para lidar com alunos que apresentam dificuldades no aprendizado. Dentre as maiores dificuldades estão: a falta de recursos que os mesmos possuem e a superlotação das salas de aula. Notamos também que, mesmo tendo dificuldades, os professores praticam a inclusão escolar, aplicando provas mediadas e fazendo uso de outras estratégias.

Oscillatory Exchange Coupling and Positive Magnetoresistance in Epitaxial Oxide Heterostructures

Oscillations in the exchange coupling between ferromagnetic $La_{2/3}Ba_{1/3}MnO_3$ layers with paramagnetic $LaNiO_3$ spacer layer thickness has been observed in epitaxial heterostructures of the two oxides. This behavior is explained within the RKKY model employing an {\it ab initio} calculated band structure of $LaNiO_3$, taking into account strong electron scattering in the spacer. Antiferromagnetically coupled superlattices exhibit a positive current-in-plane magnetoresistance.Comment: 4 pages (RevTeX), 5 figures (EPS
