Educação e cidadania : exigências à formação docente

Um dos grandes desafios da educação encontra-se na formação inicial de professores; questão que ocasiona um fenômeno social preocupante dada a sua influência na qualidade do ensino. É fundamental olhar para o futuro pedagogo e refletir as exigências de uma formação voltada para atender aos chamados da sociedade em suas contradições sociais. Este estudo insere-se na linha de pesquisa Supervisão Pedagógica e Formação de Formadores, possui como temática central o curso de formação de professores com locus na graduação em Pedagogia e concretizou-se com uma pesquisa bibliográfica e uma pesquisa de campo de caráter qualiquantitativa. Para a sua realização analisamos o Projeto Pedagógico do Curso de Pedagogia da Instituição de Ensino Superior Mario Schenberg, aplicamos questionários semiestruturados aos alunos e egressos do curso e realizamos a observação participante. Esta investigação nos permitiu constatar nossas hipóteses levantadas, reforçando a nossa convicção de que as exigências da formação do pedagogo promovedoras de uma educação transformadora têm sua alavanca na formação inicial e que as habilidades e competências necessárias ao pedagogo, para que possa atuar em prol de uma educação para a cidadania, estão relacionadas ao desenvolvimento de saberes pedagógicos, metodológicos e conceituais, ou seja, uma sólida formação teórico-prática.

Formação Continuada e Qualificação Profissional dos professores de Sobral – CE : múltiplos olhares

Esta pesquisa tem como objetivo analisar como a formação continuada contribui para a qualificação profissional dos professores a partir do olhar dos docentes, alunos e gestores. Buscamos o respaldo teórico dos autores como Nóvoa (2007), Tardif (2002), Pimenta (2000) e os saberes sociológicos e filosóficos de Santos (2007). A pesquisa empírica foi desenvolvida através de questionários com os diferentes segmentos da escola e análise documental referente às políticas de formação continuada dos professores adotadas pela Secretaria de Educação do Ceará. A análise dos dados buscou compreender como a formação continuada influenciou a competência docente. Os dados obtidos revelam que as propostas dos cursos de formação continuada do professor, adotadas nas escolas estaduais de Sobral-CE, embora defenda a profissionalização docente, na realidade ainda não contemplam práticas que valorizam os diferentes saberes produzidos na prática do professor e não promovem capacidade reflexiva capaz de contribuir de forma ativa e transformadora nos projetos pedagógicos, entendendo e atendendo a demanda escolar. A análise dos resultados da pesquisa evidencia a importância da parceria entre as instituições de ensino. No entanto essa parceria precisa reconhecer e valorizar culturas existentes entre a prática pedagógica e o conhecimento científico elaborado socialmente.

A influência do protestantismo na educação do colégio Americano Batista em Pernambuco

Em início do século XX, no ano de 1905, no momento que se afigurou promissor, foi fundado o Colégio Americano Batista-C.A.B. Já predominava no Brasil o ensino religioso ministrado pelos Jesuítas vindos de Portugal. Fora um trabalho evangelístico-educacional, numa concepção de reeligere, numa cosmovisão unirreligiosa. Os conteúdos dessa disciplina ficavam sob a responsabilidade da igreja, visto ser ela considerada à única com habilidades plausíveis. José Eduardo Franco, (2006, p.311), em seu artigo O mito dos Jesuítas em Portugal - século XVI-XX menciona que “Portugal não teve, no seu território, nenhuma origem religiosa que tivesse obtido em tão elevado grau, o prestígio e o renome, que a partir de 1540, os Jesuítas conquistaram. Mas também nenhuma outra instituição religiosa foi julgada de forma tão dupla contraditória”. A despeito das possíveis qualidades do trabalho efetuado pelos Jesuítas, ou porventura, o aflorar de suas limitações, não é o que neste trabalho de pesquisa pretendemos analisar particularmente. Propomos investigar como o ensino religioso protestante tem influenciado a educação do Colégio Americano Batista desde as suas origens à atualidade sem excluir a promulgação da Lei de Diretrizes e Bases da Educação Nacional-9.394/96 e com a estrutura do ensino religioso mediante a produção dos Parâmetros Curriculares Nacionais-PCNs. Utilizamos como material empírico os depoimentos de docentes, discentes, e de toda a equipe técnica e pedagógica desta instituição. Pretendemos com tal metodologia assegurar a dimensão da influência do Ensino Religioso na educação como agente transformador na sociedade. Compreendemos a relevância desta pesquisa, à medida que observamos a interação do diálogo interreligioso e o avanço obtido quanto à concepção catequética numa passagem para uma nova concepção de ensino religioso, na concepção do sentido para a vida.

A transversalidade do tema meio ambiente na prática pedagógica

A educação é notadamente uma das ações mais importantes de mobilização socioambiental e cada vez mais se reconhece o papel transformador da escola frente às problemáticas ambientais. No ano de 1997 o Brasil publicou os PCNs (Parâmetros Curriculares Nacionais) que traziam os Temas Transversais, dentre eles o Meio Ambiente, para serem inseridos no cotidiano escolar. Esse contexto serviu de base para nossa investigação que teve por objetivo verificar como se dá a abordagem do tema Meio Ambiente, no que se refere à sua transversalidade, na prática pedagógica entre professores e alunos do ensino fundamental. Para tanto foi utilizada uma abordagem quanti-qualitativa, utilizando-se de técnicas como questionário e entrevistas, envolvendo 12 professores e 357 alunos de escolas públicas estaduais e municipais de dois municípios vizinhos, localizados no estado de Pernambuco, Brasil. A investigação esteve apoiada no pensamento de diversos autores, dentre os quais destacamos Carvalho, I. (2004, 2006, 2007); Gadotti, M. (2005, 2008, 2010); Gavidia, V. (2002); Guimarães, M. (2003, 2004, 2009); Leff, E. (2007, 2008, 2009, 2010); Loureiro, C. (2004, 2005, 2006); Reigotta, M. (2007, 2008, 2009) e Yus, R. (1998, 2002). Com a análise dos dados obtidos concluímos que o trabalho docente envolvendo o tema Meio Ambiente ainda não atingiu o patamar transversal, embora utilizando abordagens significativas, como projetos pedagógicos, a prática interdisciplinar que a transversalidade requer ainda não foi consolidada, indicando a necessidade de aperfeiçoamento profissional - teórico e prático - sobre a aplicabilidade do tema.

Children's sociospatial (re)production of disability within primary school playgrounds

There is a contemporary shift in the institutional context of 'disabled' children's education in the United Kingdom from segregated special to mainstream schools. This change is tied to wider deinstitutionalised or reinstitutionalised geographies of disabled people, fragile globalised educational 'inclusion' agendas, and broader concerns about social cohesiveness. Although coeducating children is expected to transform negative representations of (dis)ability in future society, there are few detailed explorations of how children's everyday sociospatial practices (re)produce or transform dominant representations of (dis)ability. With this in mind, children's contextual and shifting performances of (dis)ability in two case study school playground (recreational) spaces are explored. The findings demonstrate that children with mind-body differences are variously (dis)abled, in comparison with sociospatially shifting norms of ability, which have body, learning, and emotional-social facets. The discussion therefore places an emphasis on the need to incorporate 'intellectual' and 'emotional' differences more fully into geographical studies of disability and identity. The paper has wider resonance for transformative expectations placed on colocating children with a variety of 'axes of difference' (such as gender, 'race, ethnicity, and social class) in schools.

Steady periodic water waves with constant vorticity: regularity and local bifurcation

This paper studies periodic traveling gravity waves at the free surface of water in a flow of constant vorticity over a flat bed. Using conformal mappings the free-boundary problem is transformed into a quasilinear pseudodifferential equation for a periodic function of one variable. The new formulation leads to a regularity result and, by use of bifurcation theory, to the existence of waves of small amplitude even in the presence of stagnation points in the flow.

Marguerite Duras and colonialist discourse: an intertextual reading of 'L'Empire français' and 'Un barrage contre le Pacifique'

This article examines the intertextual relationship between Marguerite Duras' pro-colonialist, propagandist text, L'Empire français (1943), and her seemingly anti-colonialist novel, Un barrage contre le Pacifique (1950). It explores both the transformative and the emulative uses to which descriptive elements, borrowed from the precursor text, are put in the novel's depictions of colonial Indochina. Going against prevalent critical readings of Barrage, the article highlights the ambivalent and ultimately only partial nature of Duras' apparent ideological volte-face

Real-time application of a constrained predictive controller based on dynamic neural networks with feedback linearization

This paper describes an experimental application of constrained predictive control and feedback linearisation based on dynamic neural networks. It also verifies experimentally a method for handling input constraints, which are transformed by the feedback linearisation mappings. A performance comparison with a PID controller is also provided. The experimental system consists of a laboratory based single link manipulator arm, which is controlled in real time using MATLAB/SIMULINK together with data acquisition equipment.

Climate change and the emergence of new organizational landscapes

There is general agreement across the world that human-made climate change is a serious global problem,although there are still some sceptics who challenge this view. Research in organization studies on the topic is relatively new. Much of this research, however, is instrumental and managerialist in its focus on ‘win-win’ opportunities for business or its treatment of climate change as just another corporate social responsibility (CSR) exercise. In this paper, we suggest that climate change is not just an environmental problem requiring technical and managerial solutions; it is a political issue where a variety of organizations – state agencies, firms, industry associations, NGOs and multilateral organizations – engage in contestation as well as collaboration over the issue. We discuss the strategic, institutional and political economy dimensions of climate change and develop a socioeconomic regimes approach as a synthesis of these different theoretical perspectives. Given the urgency of the problem and the need for a rapid transition to a low-carbon economy, there is a pressing need for organization scholars to develop a better understanding of apathy and inertia in the face of the current crisis and to identify paths toward transformative change. The seven papers in this special issue address these areas of research and examine strategies, discourses, identities and practices in relation to climate change at multiple levels.

Stakeholder inclusivity in social and environmental report assurance

Purpose – The purpose of the research was to discover the process of social and environmental report assurance (SERA) and thereby evaluate the benefits, extent of stakeholder inclusivity and/or managerial capture of SERA processes and the dynamics of SERA as it matures. Design/methodology/approach – This paper used semi-structured interviews with 20 accountant and consultant assurors to derive data, which were then coded and analysed, resulting in the identification of four themes. Findings – This paper provides interview evidence on the process of SERA, suggesting that, although there is still managerial capture of SERA, stakeholders are being increasingly included in the process as it matures. SERA is beginning to provide dual-pronged benefits, adding value to management and stakeholders simultaneously. Through the lens of Freirian dialogic theory, it is found that SERA is starting to display some characteristics of a dialogical process, being stakeholder inclusive, demythologising and transformative, with assurors perceiving themselves as a “voice” for stakeholders. Consequently, SERA is becoming an important mechanism for driving forward more stakeholder-inclusive SER, with the SERA process beginning to transform attitudes of management towards their stakeholders through more stakeholder-led SER. However, there remain significant obstacles to dialogic SERA. The paper suggests these could be removed through educative and transformative processes driven by assurors. Originality/value – Previous work on SERA has involved predominantly content-based analysis on assurance statements. However, this paper investigates the details of the SERA process, for the first time using qualitative interview data.

What (science for) adaptation to climate change in Colombian agriculture? A commentary on “A way forward on adaptation to climate change in Colombian agriculture: perspectives towards 2050” by J. Ramirez-Villegas, M. Salazar, A. Jarvis, C. E. Navarro-Valcines.

Climate change is putting Colombian agriculture under significant stress and, if no adaptation is made, the latter will be severely impacted during the next decades. Ramirez-Villegas et al. (2012) set out a government-led, top-down, techno-scientific proposal for a way forward by which Colombian agriculture could adapt to climate change. However, this proposal largely overlooks the root causes of vulnerability of Colombian agriculture, and of smallholders in particular. I discuss some of the hidden assumptions underpinning this proposal and of the arguments employed by Ramirez-Villegas et al., based on existing literature on Colombian agriculture and the wider scientific debate on adaptation to climate change. While technical measures may play an important role in the adaptation of Colombian agriculture to climate change, I question whether the actions listed in the proposal alone and specifically for smallholders, truly represent priority issues. I suggest that by i) looking at vulnerability before adaptation, ii) contextualising climate change as one of multiple exposures, and iii) truly putting smallholders at the centre of adaptation, i.e. to learn about and with them, different and perhaps more urgent priorities for action can be identified. Ultimately, I argue that what is at stake is not only a list of adaptation measures but, more importantly, the scientific approach from which priorities for action are identified. In this respect, I propose that transformative rather than technical fix adaptation represents a better approach for Colombian agriculture and smallholders in particular, in the face of climate change.

Addressing uncertainty in adaptation planning for agriculture

We present a framework for prioritizing adaptation approaches at a range of timeframes. The framework is illustrated by four case studies from developing countries, each with associated characterization of uncertainty. Two cases on near-term adaptation planning in Sri Lanka and on stakeholder scenario exercises in East Africa show how the relative utility of capacity vs. impact approaches to adaptation planning differ with level of uncertainty and associated lead time. An additional two cases demonstrate that it is possible to identify uncertainties that are relevant to decision making in specific timeframes and circumstances. The case on coffee in Latin America identifies altitudinal thresholds at which incremental vs. transformative adaptation pathways are robust options. The final case uses three crop–climate simulation studies to demonstrate how uncertainty can be characterized at different time horizons to discriminate where robust adaptation options are possible. We find that impact approaches, which use predictive models, are increasingly useful over longer lead times and at higher levels of greenhouse gas emissions. We also find that extreme events are important in determining predictability across a broad range of timescales. The results demonstrate the potential for robust knowledge and actions in the face of uncertainty.

Fractal spatialities

This paper argues for the use of ‘fractals’ in theorising sociospatial relations. From a realist position, a nonmathematical but nonmetaphoric and descriptive view of ‘fractals’ is advanced. Insights from the natural sciences are combined with insights on the position of the observer from Luhmann and notions of assemblages and repetitions from Deleuze. It is argued that the notion of ‘fractals’ can augment current understanding of sociospatialities in three ways. First, it can pose questions about the scalar position of the observer or the grain of observation; second, as a signifier of particular attributes, it prompts observation and description of particular structuring processes; and third, the epistemic access afforded by the concept can open up possibilities for transformative interventions and thereby inform the same. The theoretical usefulness of the concept is demonstrated by discussing the territory, place, scale, and networks (TPSN) model for theorising sociospatial relations advanced by B Jessop, N Brenner, and M Jones in their 2008 paper “Theorizing sociospatial relations”, published in this journal (volume 26, pages 389–401). It is suggested that a heuristic arising from a ‘fractal’ ontology can contribute to a polymorphous, as opposed to polyvalent, understanding of sociospatial relations.

Cross-layer design of enhanced AMC with truncated ARQ protocols

Using a cross-layer approach, two enhancement techniques applied for adaptive modulation and coding (AMC) with truncated automatic repeat request (T-ARQ) are investigated, namely, aggressive AMC (A-AMC) and constellation rearrangement (CoRe). Aggressive AMC selects the appropriate modulation and coding schemes (MCS) to achieve higher spectral efficiency, profiting from the feasibility of using different MCSs for retransmitting a packet, whereas in the CoRe-based AMC, retransmissions of the same data packet are performed using different mappings so as to provide different degrees of protection to the bits involved, thus achieving mapping diversity gain. The performance of both schemes is evaluated in terms of average spectral efficiency and average packet loss rate, which are derived in closed-form considering transmission over Nakagami-m fading channels. Numerical results and comparisons are provided. In particular, it is shown that A-AMC combined with T-ARQ yields higher spectral efficiency than the AMC-based conventional scheme while keeping the achieved packet loss rate closer to the system's requirement, and that it can achieve larger spectral efficiency objectives than that of the scheme using AMC along with CoRe.
