Abordagem de redes no estudo de movimentos sociais: entre o modelo e a metáfora

Este artigo faz parte de um conjunto de reflexões sobre as consequências do uso de abordagens fortemente influenciadas pela lógica empresarial como lentes para compreender movimentos orientados pela oposição a essa lógica. Neste artigo a preocupação é retomada, aprofundando a abordagem de redes. O ponto de partida foi uma apropriação crítica de autores e formulações representativos dessa abordagem. Foi impossível deixar de lado a hibridização entre a(s) teoria(s) do capital social e a abordagem de redes sociais. Parte deste artigo redundou em retirar as formulações de Pierre Bourdieu da vala comum, em que leituras equivocadas as têm jogado, ao classificálo como um teórico do capital social e da análise de redes. Também é revisada a expressão predominante da abordagem de redes nos estudos sobre movimentos sociais. Finalmente é abordada a distinção entre metáfora e modelo. A partir daí se pode afirmar que a retomada da estratégia discursiva da metáfora poderia abrir espaço para reconhecer o novo, o que está em construção, e o que ainda não é. Além disso, possibilitariam a coerência com a razão de ser do objeto a ser estudado. Nesse sentido são apresentadas três metáforas - fluidos, teias e rizomas - de modo a ilustrar as potencialidades contidas no uso desse recurso no estudo de movimentos sociais.

Linguagem fílmica: uma metáfora de comunicação para a análise dos discursos nas organizações

O objetivo da pesquisa aqui relatada foi investigar a linguagem fílmica como metáfora de comunicação para a análise dos discursos nas organizações. Trata-se de uma pesquisa qualitativa, com uso da estratégia de análise fílmica. Os dados foram coletados por meio da observação indireta e não participante, registrados em protocolo de observação. Foi utilizada a estratégia de análise de discurso do personagem do Rei George VI no filme comercial/artístico O discurso do rei; a análise documental do filme documentário The king speaks - "The true story behind the film" e a análise de conteúdo da obra literária biográfica O discurso do rei - "Como um homem salvou a monarquia britânica". Nos resultados, reforçou-se que o uso da linguagem fílmica, nesta pesquisa, contribui para o entendimento do fenômeno da comunicação nas organizações. Seu uso cria a oportunidade de simulação a partir de cenas que podem ser comparadas com dados inseridos no contexto organizacional, como metáforas, desde que haja cuidado com a dimensão afetiva envolvida no processo de significação fílmica. Sua utilização torna-se conveniente, desde que não se permita a escolha do filme pelo filme e que haja um alinhamento entre o filme escolhido e o construto que se pretende investigar.

Temporal Geobiotic Mapping: a conceptual mapping technique toward visualising geobiotic areas in cross-section

Geobiota are defined by taxic assemblages (i.e., biota) and their defining abiotic breaks, which are mapped in cross-section to reveal past and future biotic boundaries. We term this conceptual approach Temporal Geobiotic Mapping (TGM) and offer it as a conceptual approach for biogeography. TGM is based on geological cross-sectioning, which creates maps based on the distribution of biota and known abiotic factors that drive their distribution, such as climate, topography, soil chemistry and underlying geology. However, the availability of abiotic data is limited for many areas. Unlike other approaches, TGM can be used when there is minimal data available. In order to demonstrate TGM, we use the well-known area in the Blue Mountains, New South Wales (NSW), south-eastern Australia and show how surface processes such as weathering and erosion affect the future distribution of a Moist Basalt Forest taxic assemblage. Biotic areas are best represented visually as maps, which can show transgressions and regressions of biota and abiota over time. Using such maps, a biogeographer can directly compare animal and plant distributions with features in the abiotic environment and may identify significant geographical barriers or pathways that explain biotic distributions.

Las competencias desde la perspectiva informacional: apuntes introductorios a nivel terminológico y conceptual, escenarios e iniciativas

En la actualidad, las organizaciones tienen que enfrentar los cambios en la tecnología, adecuarse a la nueva organización del trabajo y lograr ventajas en el mercado. Para ello, las competencias de los individuos juegan un papel vital, y su gestión se convierte en factor clave para la supervivencia de las mismas. Este enfoque de competencias laborales y/o profesionales, unido a la sociedad de hoy, llamada de la información hace imprescindible las competencias informacionales. Para poder llevar a cabo un estudio aplicado sobre éstas es preciso contar con un acervo teórico-conceptual. A partir de ello, este trabajo tiene como objetivos mostrar, tomando en cuenta primeramente el concepto de competencias, qué se entiende por competencias informacionales a nivel terminológico y conceptual; demostrar, mediante los diferentes escenarios, cómo las competencias informacionales se imponen; y mostrar mediante las distintas iniciativas cómo cada vez resulta más importante su gestión. El trabajo se basa en el análisis documental.

Information literacy - historical and conceptual bases: constructing meanings

Recent years have witnessed the increasing interest in studies focused on information literacy, which is reflected mainly in the number of publications on the subject and goes beyond the fields of Librarianship and Information Science. The purpose of this paper is, therefore, to offer an outlook, historical and conceptual, of international researches on information literacy, trying to show some of the different ramifications which the discussion on the subject has exhibited in past few years in countries where its process of legitimation is already well established, in order to illuminate possible areas of research and action for the librarian professional. This research indicates that if the initial studies on this topic tended to be devoted to conceptualize it, discussing its relevance and determine the skills and knowledge related to information literacy, in the last decade can be noticed a proliferation of researches aimed at describing initiatives or proposing models in areas beyond the usual field such as Medical Sciences, Law, Politics or Computers, among others. The first results of this research refer to a philosophical and educational perspective of information literacy, which suggests the need for deeper understanding and characterization of information literacy in four dimensions: technical, aesthetic, ethical and political, serving both to competence as to information.

Do general chemistry textbooks facilitate conceptual understanding?

Research in chemistry education has recognized the need for facilitating students' understanding of different concepts. In contrast, most general chemistry curricula and textbooks not only ignore the context in which science progresses but also emphasize rote learning and algorithmic strategies. A historical reconstruction of scientific progress shows that it inevitably leads to controversy and debate, which can arouse students' interest and thus facilitate understanding. The objective of this article is to review research related to the evaluation of general chemistry textbooks (based on history and philosophy of science, HPS) and suggest alternatives that can facilitate conceptual understanding.

Caracterización de la reactividad intrínseca de los halobencenos en el modelo conceptual de la teoría de funcionales de la densidad (TFD)

The aim of this paper is to study the family of halobenzenes for characterizing their intrinsic reactivity and in this way to establish a rational order of the intrinsic reactivity of this family of molecules in the electrophilic aromatic substitution. This study was carried out in the framework of Density Functional Theory which provides a global and local index that can be used in the characterization of the reactivity. This index is related to some concept derivatives of experimental chemistry, being a good approach to the characterization of halobenzenes.

Propuesta de un test para determinar el conocimiento conceptual de estudiantes universitarios sobre la constante de equilibrio químico y su aplicación en estudiantes españoles

This article outlines a procedure that was used to develop a written test for evaluating the conceptual knowledge of chemical equilibrium constant among university students. The concepts in the subject matter were carefully defined through propositional statements. Students' understanding of the topic was determined through interviews. These data were used to produce nine multiple choice questions. Each question was designed to identify misconceptions related to the chemical equilibrium constant. The test was evaluated by foure associate professors and was administred to a total of 196 spanish university students. This test has a Cronbach's alpha reliability of 0.63 and its content validity values ranged from 3.7 to 5.

Boundless thought. The case of conceptual mental episodes

I present and defend here a thesis named vehicleless externalism for conceptual mental episodes. According to it, the constitutive relations there are between the production of conceptual mental episodes by an individual and the inclusion of this individual in social discursive practices make it non-necessary to equate, even partially, conceptual mental episodes with the occurrence of physical events inside of that individual. Conceptual mental episodes do not have subpersonal vehicles; they have owners: persons in interpretational practices. That thesis is grounded on inferentialism and on the endorsement of the idea that "meaning is normative". After having recapitulated this heritage and after having presented that thesis, the paper especially attempts to articulate how, in that framework, we may then positively conceive the relations there are between conceptual mental episodes, intracranial events and inferential behaviour.
