Abstract Pierre Bourdieu’s theoretical contributions pave the way for studying a wide range of social spaces, such as the academia. Through using Bourdieusian fields, our objective was to investigate whether the teaching area of the Coordination for the Improvement of Higher Education Personnel (CAPES) can be considered a relatively autonomous scientific field. Therefore, this study is motivated by two research questions: 1) what is the distribution of scientific capital in the teaching area; and 2) what are the implications of this distribution on its constitution as a scientific field. By crossing data on professors of programs in the field of education with the evaluation grade assigned by Capes to each of these programs, our analysis revealed that this area does not constitute a scientific field. Differently from what happens in well-established fields, most teaching advisors come from many different scientific backgrounds and do not recognize this field’s specific intellectual production as scientific capital. Assuming that the existing disputes between professors with less and more scientific capital can generate new conformations in the area, a possible structure could be a stabilization of the subgroup of professors with greater scientific capital and its constitution as a scientific field, whose agents become increasingly aware that their cognitive structure and ideals of education/research are different from what Capes intended to homogenize with the creation of a teaching area. We believe that our results can be a reference for critical reflection on the structure of the field of teaching, which is still driven by its agents.

The fossil record of bioerosion on rudists is commonly restricted to brief mentions that mainly use general terms and do not constitute detailed ichnological studies. This contribution comprises a detailed study of the bioerosion structures present on the shells of different species of rudists from the Upper Cretaceous (Maastrichtian) of Cuba. In addition, paleobiological, paleoecological and taphonomic implications of these boring are inferred. Among the studied material, seventeen rudist shells exhibits bioerosion structures. Based on their morphological features the borings have been ascribed to Gastrochaenolites isp. and Entobia isp. Gastrochaenid bivalves and clionaid sponges, respectively, have been proposed as their more likely producers. The modes of occurrence, density, and position of such bioerosion structures rule out a syn-vivo relationship between rudists and boring bivalves and sponges, demonstrating that colonization mainly was postmortem. Furthermore, the combination of these data together with previous paleoecological interpretations and the fact that the most parts of the rudist shells are filled by sediment, provides enough evidence to propose a subsequent process of reworking and reburial of these shells in shallow marine settings.

Anomalocardia flexuosa is a bivalve that inhabits shallow, low hydrodynamics coastal environments of normal to brackish salinity, currently distributed from the Caribbean up to the state of Santa Catarina (∼28°S) in southern Brazil, but its fossil record extends along the southwestern Atlantic up to ∼40°S, in Argentina. Its absence in southern coasts today is attributed to ocean water cooling as a result of Middle-Late Holocene changes in relative influence of the warm waters of the Brazil Current and the cold waters of the Malvinas/Falklands Current, but geomorphologic and stratigraphic data suggest that coastal evolution controlled mainly by glacioeustatic-driven oscillations may have also played a role on the shifts of its distribution. Here we review the past and present distribution of A. flexuosa along southern Brazil, establishing a correlation with the Holocene geological history of this area. The Holocene post glacial marine transgression (PMT) produced a large complex of interconnected coastal lagoons landward of sandy barriers stretching from southern Brazil (state of Rio Grande do Sul) to Argentina, creating a corridor that allowed for the southward dispersion of A. flexuosa. The few available numerical ages indicate that A. flexuosa was established in the northern coastal plain of Rio Grande do Sul around ∼7.1 ka BP, and by ∼5.8 ka BP it had reached the southern plain, facilitated by warmer ocean waters than today and the sea-level highstand of 6–5 ka BP. The combination of cooling, sea-level fall that reduced marine influence, and fluvial inputs of freshwater and sediments, converted most of the lagoon complex into smaller isolated freshwater lakes after ∼4 ka BP, leading to the regional extinction of that species. The fossils of A. flexuosa and other tropical mollusks in middle and late Pleistocene interglacial barrier-lagoon coastal deposits along the southwestern Atlantic suggest that their latitudinal distribution shifted cyclically, driven by glacial-interglacial oscillations of sea-level and temperatures. The understanding of the coastal processes that affected the distribution of A. flexuosa may help assessing how mollusks and other marine species respond to environmental forcings related to sea-level oscillations and climate, thus contributing from a paleobiological perspective for conservation and management efforts under present and future scenarios of changes in coastal ecosystems.

Nos cursos de licenciatura, usualmente, as discussões sobre Epistemologia são feitas de forma desconectada das discussões técnicas, muitas vezes realizadas apenas em disciplinas específicas. Buscando romper com esse abismo entre os conteúdos técnicos e pedagógicos das licenciaturas em Física, apresentamos uma análise de um curso de extensão sobre Astrofísica e Epistemologia, oferecido para professores de ciências e licenciandos de Física. Nesse curso, diferentes episódios da Astronomia e Astrofísica foram discutidos à luz de diferentes concepções epistemológicas. Nosso objetivo era permitir que os alunos refletissem sobre suas próprias concepções, confrontando-as com as diferentes possibilidades apresentadas. Para avaliar a intervenção, foi realizado um pré-teste e pós-teste, em que os participantes expressavam sua concordância com 10 enunciados sobre natureza da ciência. As respostas foram analisadas usando o método estatístico de Escalonamento Multidimensional. Nossos resultados mostram que, inicialmente, as respostas não apresentavam consistência interna e os participantes exibiam o mesmo grau de concordância em relação a visões concorrentes sobre a natureza da ciência. Após o curso, os participantes passaram a se posicionar de forma mais coerente, concordando com características de uma mesma visão epistemológica e se afastando de visões concorrentes.

The few passages in Spinoza’s work in which he focuses on the concept of human law have not received as much scholarly attention as passages focused on other themes, but they have still been very well examined, as evidenced by, for example, the collection edited by André Campos in 2015, which brought together 21 articles written between 1948 and 2010.It is true that most of these studies do not directly aim to determine whether Spinoza adopts a normative conception of human law in the political-legal field or, if he does adopt such a conception, what the conditions under which he could do so could be, given the logical-causal necessitarianism and naturalism of his metaphysics, explicitly reaffirmed in paragraph 3 of Chapter IV of the TTP. However, this problem is unavoidable, and it is precisely to this matter that I would like to contribute, in a rather modest way, by examining the answer that Spinoza himself offers in the passage just cited.

Neste texto, discuto a interpretação defendida por Moyal-Sharrock, segundo a qual as proposições eixo são maneiras de agir com o objetivo de oferecer uma proposta sobre como compreendê-las. Sustento que a posição de Moyal-Sharrock deixa algumas lacunas, porque não explica a origem das nossas certezas fundamentais. A sua leitura também carece de recursos para responder ao problema da demarcação, uma vez que não é claro como distinguir maneiras de agir que podem legitimamente cumprir o papel de fundamento não fundamentado das que não podem. Sem uma resposta para esse problema, a ameaça relativista é séria. Proponho, então, que as proposições eixo são maneiras de agir constitutivas de habilidades. Desenvolvo também uma abordagem ecológica das habilidades, a qual me possibilita explicar por que habilidades são embebidas-de-realidade e, por conseguinte, por que as maneiras de agir que as constituem são fundamentos não fundamentados legítimos. Com base nessa abordagem, ofereço uma resposta para o problema da demarcação que afasta a ameaça relativista.

In this paper, I explore and examine different ways in which affectivity is related to perception within ecological psychology. I assess whether some of those ways compromise the realist and direct aspects of traditional ecological perception. I sustain that they don’t. Affectivity, at least in some cases, turns the perception of fine-grained affordances possible. For an engaged perceiver, affectivity is not optional.

Este trabalho apresenta o projeto de extensão Agricultura Urbana e Periurbana, Alimentação, Educação e Saúde, iniciado em 2018 pela Universidade Federal do Rio Grande do Sul, no Campus Litoral Norte. O diálogo entre a universidade, gestores públicos, escolas, organizações não-governamentais e moradores da região fomentou o debate sobre agricultura, agroecologia, alimentação e saúde. Percebeu-se que havia demanda por cursos teórico-práticos que pudessem consolidar a formação técnica em torno dessas temáticas. O projeto iniciou realizando um mapeamento das hortas comunitárias urbanas e periurbanas na região e ofereceu cursos fomentando a inclusão de populações vulneráveis, articulando o direito humano à alimentação e o direito à cidade, propondo o aumento da produção de alimentos no espaço urbano.

In this paper, I argue that hinge propositions are ways of acting that constitute abilities or skills. My starting point is Moyal-Sharrock’s account of hinge propositions. However, Moyal-Sharrock’s account leaves gaps to be filled, as it does not offer a unified explanation of the origin of our ungrounded grounds. Her account also lacks resources to respond to the issue of demarcation, since it does not provide a criterion for distinguishing ways of acting that can legitimately fulfill the role of ungrounded grounds from those that cannot. Without an answer to this issue, the relativistic threat is serious. I then propose that by narrowing the ways of acting to those that are constitutive of abilities, we can deal with the relativistic threat. I provide an ecological approach to abilities through which I explain why abilities are reality-soaked and therefore why the ways of acting that constitute them are legitimate ungrounded grounds. Based on that approach, I provide an
answer to the issue of demarcation that defuses the relativistic threat.

Tomamos como certo que os nossos sentidos nos colocam em contato com o ambiente ao nosso redor. Enquanto caminhamos em uma rua, vemos obstáculos que temos de contornar ou remover. Mesmo de costas, podemos ouvir a bicicleta que se aproxima e dar passagem. Em suma, por meio de experiências perceptivas (visuais, auditivas, olfativas etc.), ficamos conscientes de objetos ou eventos que estejam ocorrendo ao nosso redor. Além disso, com base no que percebemos, podemos formar e manter crenças acerca do ambiente e, assim, adquirir conhecimento perceptivo acerca do mundo. A importância desse conhecimento acerca do que está ao nosso alcance perceptivo é inestimável para a nossa sobrevivência e a condução de nossos projetos cotidianos. Contudo, podemos querer saber (1) se de fato temos acesso ao mundo físico circundante por meio das nossas experiências perceptivas, e (2) se e como essas experiências justificam as nossas crenças acerca do que percebemos. Esses problemas são centrais para a epistemologia da percepção, embora não sejam os únicos. Nessa entrada, abordaremos esses dois problemas.
