Texto e dialogismo no estudo da memória coletiva
As ideias bakhtinianas sobre texto e dialogismo oferecem ferramentas importantes para trazer ordem ao caótico e fragmentado campo dos estudos da memória coletiva. Embora a definição de memória coletiva neste momento ainda esteja por ser resolvida, é possível obter alguma compreensão do espectro de opções, situando-se as discussões em termos do contraste entre versões fortes e distribuídas da memória coletiva. Tendo por base a noção de mediação semiótica e as afirmações a ela relacionadas sobre uma versão distribuída da memória coletiva, invoca-se a noção bakhtiniana de texto dialogicamente organizado. O fato de que o 'sistema da linguagem' concebido por Bakhtin inclui as orientações dialógicas do diálogo coletivo, generalizado assim como os elementos gramaticais padrão, significa que ele introduz um elemento essencial de dinamismo na memória coletiva.Bakhtinian ideas about text and dialogism provide important tools for bringing order to the otherwise chaotic and fragmented field of collective memory studies. While the definition of collective remembering may remain unsettled at this point, some appreciation of the range of options can be derived by situating discussions in terms of the contrast between strong and distributed versions of collective remembering. Building on the notion of semiotic mediation and associated claims about a distributed version of collective remembering, Bakhtin's notion of dialogically organized text is invoked. The fact that the "language system" envisioned by Bakhtin includes the dialogical orientations of generalized collective dialogue as well as standard grammatical elements means that it introduces an essential element of dynamism into collective remembering
Early respiratory viral infections in infants with cystic fibrosis
This article is made available for unrestricted research re-use and secondary analysis in any form or by any means with acknowledgement of the original source. These permissions are granted for the duration of the World Health Organization (WHO) declaration of COVID-19 as a global pandemic.Background
Viral infections contribute to morbidity in cystic fibrosis (CF), but the impact of respiratory viruses on the development of airway disease is poorly understood.
Methods
Infants with CF identified by newborn screening were enrolled prior to 4 months of age to participate in a prospective observational study at 4 centers. Clinical data were collected at clinic visits and weekly phone calls. Multiplex PCR assays were performed on nasopharyngeal swabs to detect respiratory viruses during routine visits and when symptomatic. Participants underwent bronchoscopy with bronchoalveolar lavage (BAL) and a subset underwent pulmonary function testing. We present findings through 8.5 months of life.
Results
Seventy infants were enrolled, mean age 3.1 ± 0.8 months. Rhinovirus was the most prevalent virus (66%), followed by parainfluenza (19%), and coronavirus (16%). Participants had a median of 1.5 viral positive swabs (range 0–10). Past viral infection was associated with elevated neutrophil concentrations and bacterial isolates in BAL fluid, including recovery of classic CF bacterial pathogens. When antibiotics were prescribed for respiratory-related indications, viruses were identified in 52% of those instances.
Conclusions
Early viral infections were associated with greater neutrophilic inflammation and bacterial pathogens. Early viral infections appear to contribute to initiation of lower airway inflammation in infants with CF. Antibiotics were commonly prescribed in the setting of a viral infection. Future investigations examining longitudinal relationships between viral infections, airway microbiome, and antibiotic use will allow us to elucidate the interplay between these factors in young children with CF
The principle of situated practice in literacy learning: students’ perspectives
O artigo resulta de uma investigação realizada no âmbito de uma iniciativa governamental destinada a melhorar os níveis de literacia nas séries iniciais do ensino fundamental em Portugal. A investigadora estudou as representações dos alunos sobre essa experiência por meio da realização de entrevistas em grupo. Este artigo analisa os dados referentes às representações dos alunos sobre uma das dimensões pedagógicas centrais da aprendizagem da literacia, nomeadamente a constituída pela prática situada. A análise qualitativa revela representações muito positivas sobre a prática que situou a aprendizagem, tendo os alunos expressado opiniões e sentimentos extremamente favoráveis sobre a prática de aprendizagem de literacia que experimentaram. A análise dos dados desvelou ainda que o contexto que situou a aprendizagem foi ativo, lúdico, colaborativo e mediado pelas TIC. Esses resultados fundamentam, do ponto de vista único dos próprios aprendentes, uma redefinição do entendimento atual do princípio da prática situada da literacia nas séries iniciais do ensino fundamental, no sentido do reconhecimento da centralidade da ludicidade nessa aprendizagem.This article derives from research developed in the context
of the implementation of a governmental initiative aimed to
enhance literacy learning in primary education in Portugal.
The researcher studied students’ representations about
their learning experience through group interviews. This
article focuses on data concerning students’ representations
about one of the central pedagogical dimensions of literacy
learning, namely situated practice. Qualitative analysis
revealed students’ very positive representations about the
practice which situated their learning, as they expressed
extremely favourable opinions and feelings. Data analysis
further unveiled that the context of learning was active,
playful, collaborative, and mediated by ICT. Such results
provide foundations for a theoretical redefinition of current
conceptions of situated practice by evidencing the centrality
of playfulness as learning practice in the education of the first
grades of primary education. This is an original contribution
made from the perspectives of learners themselves(undefined)info:eu-repo/semantics/publishedVersio
Embodying culture: Body pedagogics, situated encounters and empirical research
Contemporary research into the field of body pedagogics has produced a growing number of studies concerned with the embodied character of cultural transmission, experience, reproduction and change. This paper advances this sociological development by reinterpreting recent writings on situated epistemic relations (SER) and practical epistemological analysis (PEA) as complementary, methodological, techniques that can enhance these investigations. After outlining existing explorations into the body pedagogics of occupational, sporting, religious, educational and other cultures, I demonstrate how the interlinked approaches to learning made possible by systematising SER and PEA can be developed into a new approach that increases the effectiveness with which the theoretical and empirical concerns of studies into embodied acculturation are harnessed
