Entre o sistema e o mundo da vida: possibilidades de ação comunicativa na trajetória formativa de professores de Ciências

This study aimed at both identifying possibilities of communicative action that occur in the formative trajectory of Science teachers, and therefore collaborate in the discussion on the rationality approach that supports teacher education. Therefore, we hope to contribute for the construction of a formative model that encourages human emancipation. For this purpose, we draw concepts from Communicative Action Theory proposed by Jürgen Habermas. Data were obtained by half-structuralized interviews. Although strategic actions predominate among those used by teachers during their education period, we observed some tension focus could be identified, better recognized and built up in order to enlarge possibilities of increasing communicative actions in teacher education. We identified political and epistemological factors as obstacles for these possibilities to materialize.

Intencionalidades detectadas no processo de elaboração e implementação de um projeto de formação inicial de professores de física

This article presents part of a PhD research that investigated what are the limiting factors to be overcome by an initial training program for teachers of physics in order to achieve the identity profile of your proposed course on Pedagogical Project Course (PPC). From the survey of the intended ideal, the actions taken by professors, coordinators and managers seeking its implementation were analyzed. Data were collected from official documents, field notes taken during meetings between professors and interviews with the subjects belonging to the faculty of the course. This is a research in action grounded in Habermas principles. For data analysis, we used analytical devices of discourse analysis, using the French perspective of Pêcheux. The outline presented here seeks to highlight the intentions identified through the analysis of discourses present in the texts, in the speech of different subjects involved and the actions undertaken by them during this process. What one can conclude is that the intentions of the involved professors are permeated of contractions, since in some aspects they intend to give the program teacher's an identity (licenciature) and in other ones they try to maintain the status quo, that means, a teachers program which a bachelor’s profile.

Física Moderna e Contemporânea no ensino médio e a formação de professores: desencontros com a ação comunicativa e a ação dialógica emancipatórias

Taking into consideration various argumentation perspectives, the introduction of Modern and Contemporary Physics at High School level has been defended by various researchers. In the present qualitative nature research, we heard and interpreted ten High School physics teachers’ discourses, aiming to analyze how their initial education, regarding to Modern and Contemporary Physics, was based in a rationality which matches with the communicative and the dialogical actions. Teachers of our sample were individually interviewed and, at that time, they had finished their initial undergraduate program at least five years before. Teachers’ discourses interpretation was supported by some French school discourse analysis’ concepts, Jürgen Habermas’ communicative action, Freire’s dialogical action, as well as teachers’ education research critical referential. The discourses interpretations evidenced that these teachers’ education, with respect to Modern and Contemporary Physics, was mainly based in technical-instrumental rationality basis. This perspective did not help teachers’ autonomy construction in order to work these subjects in their classes, mainly in a perspective coherent with the teachers’ emancipation, producing reflexes in classroom physics teaching. The study evidenciates the necessity of future teachers’ professors revise theirs teaching practice, as well studying other curricular structures, regarding to Modern and Contemporary Physics teaching.

Aportes teóricos e metodológicos para a constituição de um grupo de planejamento conjunto com docentes da licenciatura em física

We present in this paper parts of the results of a research that had the intention to promote a space of communicative interaction among teachers of an undergraduate Course of Physics Teaching so they could plan their courses together. From the theoretical recommendations of the Theory of Communicative Action , by Jürgen Habermas , it was possible to draw a way of rationality crisis in training degree in physics in Brazil and then propose the creation of a Joint Planning Group (JPG) with teachers of specific nature disciplines of physics and disciplines about physics teaching. They start a joint discussion about the relationship among the disciplines in delivering of a project for future high school teachers' training. All meetings developed over a school year in the GPC were recorded, transcribed and analyzed with a part of a methodological analysis feature of the intersubjective interactions. This methodology was developed specifically for the research. The conclusions are related to the joint constructions developed by the JPG, its local contexts and the possibility of extension of this group. The joint constructions undertaken in the group point to the defense of the formation of JPG in the formation of the professors who teach these courses.

Perspectivas críticas na pesquisa sobre formação de professores de Ciências

This text is in theoretical study, with consideration of the authors of the critical perspective of education and training of science teachers. We indicate a set of principles and concepts of some philosophers, like Habermas and Gramsci and theoretical education in a critical bias, as Freire, Saviani, Giroux and Duarte, which can enrich the discussions in the field of science teacher education. Some of these concepts: organic intellectual philosophy of praxis, inconclusiveness, incompleteness, dialogue and problematization, communicative action, critical pedagogies of learning to learn, dialectical relationship between theory, culture and depth psychology. Thus, we intend to explain the richness of the dialogue among this perspective and its implications for the training of science teachers.

Contesting Sphere Boundaries Online: Private/Technical/Public Discourses in Polycystic Ovarian Syndrome Discussion Groups

The internet is fast becoming a means for people to obtain information, creating a unique forum for the intersection of the public, technical, and private spheres. To ground my research theoretically, I used Jürgen Habermas’s sphere theory. Habermas (1987) explains that the technical sphere colonizes the private sphere, which decreases democratic potential. In particular, the internet is a place for altering technical colonization of the private and public spheres. My research focuses on women’s health because it is a particularly useful case study for examining sphere tensions. Historically, the biomedical health establishment has been a powerful agent of colonization, resulting in detrimental effects for women and their health. The purpose of this study is to examine how the internet encourages expert and female patient deliberation, which empowers women to challenge the experts and, thus, make conversations between the private/technical spheres more democratic. I used PCOS (Polycystic Ovarian Syndrome) as a case to observe the changing sphere boundaries by studying the discourse that took place on multiple patient and doctor websites over a four-year period. Through my research, I found that the PCOS women challenge the biomedical model by appropriating medical language. By understanding the medical talk, the women are able to feel confident when discussing their health conditions with the doctor and with each other. The PCOS women also become lay-experts who have personal and medical experience with PCOS, reducing private sphere colonization. This case study exemplifies how female empowerment can influence expert culture, challenging our conventional understanding of democracy.

Stuart Hall, cultural studies e a nostalgia da dominação hegemônica

Stuart Hall é um dos poucos autores contemporâneos que ainda se apóia no conceito de ideologia. Ela interfere na língua falada definindo limites, regulando a forma discursiva com a intenção de estabilizá-la e congelá-la. Ela domina o bloco histórico e a estratégia seria a de unir as camadas populares, a partir de dentro, para que estas possam fortificar-se e combatê-la. Mas todo esse esquema tem sabor nostálgico, como se houvesse uma manobra dos poderosos e os dominados não se identificassem com os signos de poder e prestígio. Como no caso da “leitura crítica”, não seria o caso de modernizar Stuart Hall?

A publicidade contra-intuitiva e o efeito ricochete

O propósito deste artigo é compartilhar com o leitor algumas noções conceituais de publicidade contra-intuitiva e observar seus possíveis efeitos na reavaliação, desconstrução de crenças e estereótipos sociais, na estrutura cognitiva do indivíduo receptor. Destaca-se entre os reflexos provavelmente gerados o irônico efeito ricochete, segundo a teoria desenvolvida por Daniel M. Wegner. A aplicação para se discutir o cruzamento da narrativa contra-intuitiva e o efeito ricochete será, neste primeiro momento, pela exemplificação do filme Motorista, peça integrante da campanha publicitária da Fiat do Brasil “Reveja seus conceitos”, para o lançamento do automóvel Palio 2002. Um experimento laboratorial está sendo desenvolvido pelos autores para se mensurar de maneira consistente a apresentação teórico-conceitual exposta

Haploinsufficiency of a Spliceosomal GTPase Encoded by EFTUD2 Causes Mandibulofacial Dysostosis with Microcephaly

Mandibulofacial dysostosis with microcephaly (MFDM) is a rare sporadic syndrome comprising craniofacial malformations, microcephaly, developmental delay, and a recognizable dysmorphic appearance. Major sequelae, including choanal atresia, sensorineural hearing loss, and cleft palate, each occur in a significant proportion of affected individuals. We present detailed clinical findings in 12 unrelated individuals with MFDM; these 12 individuals compose the largest reported cohort to date. To define the etiology of MFDM, we employed whole-exome sequencing of four unrelated affected individuals and identified heterozygous mutations or deletions of EFTUD2 in all four. Validation studies of eight additional individuals with MFDM demonstrated causative EFTUD2 mutations in all affected individuals tested. A range of EPTUD2-mutation types, including null alleles and frameshifts, is seen in MFDM, consistent with haploinsufficiency; segregation is de novo in all cases assessed to date. U5-116kD, the protein encoded by EFTUD2, is a highly conserved spliceosomal GTPase with a central regulatory role in catalytic splicing and post-splicing-complex disassembly. MFDM is the fast multiple-malformation syndrome attributed to a defect of the major spliceosome. Our findings significantly extend the range of reported spliceosomal phenotypes in humans and pave the way for further investigation in related conditions such as Treacher Collins syndrome.

Underlying Event measurements in pp collisions at root s=0.9 and 7 TeV with the ALICE experiment at the LHC

We present measurements of Underlying Event observables in pp collisions at root s = 0 : 9 and 7 TeV. The analysis is performed as a function of the highest charged-particle transverse momentum p(T),L-T in the event. Different regions are defined with respect to the azimuthal direction of the leading (highest transverse momentum) track: Toward, Transverse and Away. The Toward and Away regions collect the fragmentation products of the hardest partonic interaction. The Transverse region is expected to be most sensitive to the Underlying Event activity. The study is performed with charged particles above three different p(T) thresholds: 0.15, 0.5 and 1.0 GeV/c. In the Transverse region we observe an increase in the multiplicity of a factor 2-3 between the lower and higher collision energies, depending on the track p(T) threshold considered. Data are compared to PYTHIA 6.4, PYTHIA 8.1 and PHOJET. On average, all models considered underestimate the multiplicity and summed p(T) in the Transverse region by about 10-30%.

Football in the dock: the case of homophobia.

This essay discusses some issues related to homophobia in football. To this was discussed through official documents and literature of the difficulties and challenges in the fight against homophobia in Brazil. From these initial discussions sought to relate the world of "male" and the reproduction of discrimination in football. As a form of analysis came from two authors of the social sciences: Durkheim's concept of anomie, which offers an explanation of why the repression of different (idea of the sacred and profane), and Habermas with the idea of civil society as a construction of mechanisms to fight for a transformation of reality and possibility of dialogue.

Determinants of discordance in patients' and physicians' rating of rheumatoid arthritis disease activity

Objective To assess the determinants of patients' (PTGL) and physicians' (MDGL) global assessment of rheumatoid arthritis (RA) activity and factors associated with discordance among them. Methods. A total of 7,028 patients in the Quantitative Standard Monitoring of Patients with RA study had PTGL and MDGL assessed at the same clinic visit on a 0-10-cm visual analog scale (VAS). Three patient groups were defined: concordant rating group (PTGL and MDGL within >= 2 cm), higher patient rating group (PTGL exceeding MDGL by > 2 cm), and lower patient rating group (PTGL less than MDGL by > 2 cm). Multivariable regression analysis was used to identify determinants of PTGL and MDGL and their discordance. Results. The mean +/- SD VAS scores for PTGL and MDGL were 4.01 +/- 2.70 and 2.91 +/- 2.37, respectively. Pain was overwhelmingly the single most important determinant of PTGL, followed by fatigue. In contrast, MDGL was most influenced by swollen joint count (SJC), followed by erythrocyte sedimentation rate (ESR) and tender joint count (TJC). A total of 4,454 (63.4%), 2,106 (30%), and 468 (6.6%) patients were in the concordant, higher, and lower patient rating groups, respectively. Odds of higher patient rating increased with higher pain, fatigue, psychological distress, age, and morning stiffness, and decreased with higher SJC, TJC, and ESR. Lower patient rating odds increased with higher SJC, TJC, and ESR, and decreased with lower fatigue levels. Conclusion. Nearly 36% of patients had discordance in RA activity assessment from their physicians. Sensitivity to the "disease experience" of patients, particularly pain and fatigue, is warranted for effective care of RA.

Measurement of prompt J/psi and beauty hadron production cross sections at mid-rapidity in pp collisions at root s=7 TeV

The ALICE experiment at the LHC has studied J/psi production at mid-rapidity in pp collisions at root s = 7 TeV through its electron pair decay on a data sample corresponding to an integrated luminosity L-int = 5.6 nb(-1). The fraction of J/psi from the decay of long-lived beauty hadrons was determined for J/psi candidates with transverse momentum p(t) > 1,3 GeV/c and rapidity vertical bar y vertical bar < 0.9. The cross section for prompt J/psi mesons, i.e. directly produced J/psi and prompt decays of heavier charmonium states such as the psi(2S) and chi(c) resonances, is sigma(prompt J/psi) (p(t) > 1.3 GeV/c, vertical bar y vertical bar < 0.9) = 8.3 +/- 0.8(stat.) +/- 1.1 (syst.)(-1.4)(+1.5) (syst. pol.) mu b. The cross section for the production of b-hadrons decaying to J/psi with p(t) > 1.3 GeV/c and vertical bar y vertical bar < 0.9 is a sigma(J/psi <- hB) (p(t) > 1.3 GeV/c, vertical bar y vertical bar < 0.9) = 1.46 +/- 0.38 (stat.)(-0.32)(+0.26) (syst.) mu b. The results are compared to QCD model predictions. The shape of the p(t) and y distributions of b-quarks predicted by perturbative QCD model calculations are used to extrapolate the measured cross section to derive the b (b) over bar pair total cross section and d sigma/dy at mid-rapidity.

Projeto terapêutico nos serviços extra-hospitalares de saúde mental: uma reflexão crítica sobre a forma de elaboração e gestão dos projetos terapêuticos nos serviços

Com base em uma pesquisa realizada no município de Ribeirão Preto, SP, em serviços extra-hospitalares de saúde mental, que teve como objetivo estudar a organização desses serviços, os projetos terapêuticos e a inserção da reabilitação psicossocial nas ações de saúde disponibilizadas, apresenta-se reflexão teórico-crítica sobre o processo de elaboração dos projetos terapêuticos pelas equipes dos serviços. A pesquisa, que foi desenvolvida em um Ambulatório e em um Centro de Atenção Psicossocial II, foi realizada com base em metodologia qualitativa; como técnicas de coleta de dados, utilizou-se entrevistas semidiretivas e grupos focais, e a análise dos dados apoiou-se em referencial hermenêutico dialético de Jürgen Habermas, seguindo técnica interpretativa reconstrutiva. A análise dos dados mostrou que os profissionais têm apresentado dificuldade na elaboração e gestão dos projetos terapêuticos. Ações de saúde são disponibilizadas sem o referencial concreto de uma proposta norteadora das atividades práticas do serviço. Os projetos terapêuticos são referenciados pelos profissionais como decorrentes das diretrizes provenientes de instâncias gestoras ou das orientações técnicas próprias a cada categoria profissional, mas não como atividade de construção representativa de uma filosofia de trabalho da equipe de saúde. Ao enfocar-se o projeto terapêutico como um tipo de consenso fundado, resultante de ação comunicativa orientada para o entendimento mútuo e intersubjetivo entre membros da equipe do serviço extra-hospitalar de saúde mental, evidencia-se a dificuldade das equipes dos serviços em organizarem-se dialogicamente para a construção coletiva do projeto terapêutico.
