Introduction: In 2020, according to the Global Cancer Observatory, nearly 10 million people died of cancer. Amongst all cancers, breast cancer had the highest number of new cases and lung cancer had the highest number of deaths. Even though the literatures suggest a possible connection between psychological factors and cancer risk, their association throughout studies remains inconclusive. The present systematic review studied the connection between psychological factors and the risk of breast and lung cancer, prior to a cancer diagnosis. The (...) psychological factors of trauma, grief, and depression were studied.Methods: The current systematic review was carried out across multiple databases in two phases, an initial exploratory research in June 2020, refined with a second electronic research in December 2020. The inclusion criteria included studies describing the association between trauma, posttraumatic stress disorder, grief, and depression with breast and lung cancer risk. The psychological data collection must have been carried out prior to a confirmed breast or lung cancer diagnosis, and accessed through self-report measures, questionnaires, clinical interviews, or clinical diagnoses. Study reports had to contain information about the incidence of cancer and effect size. The exclusion criteria were studies in which psychological factors were collected after cancer diagnosis.Results and Conclusion: A total of 26 studies were included. Although non-consensual, the findings from the present systematic review suggest that, in addition to the known risk factors, psychological factors may play an important role in the etiology of both breast and lung cancer. To include psychological factors as a variable that affects cancer development may be fundamental to opening new avenues for prevention and intervention.Systematic Review Registration: [www.ClinicalTrials.gov], identifier [CRD42020209161].

This article explores some of the most significant questions in feminist epistemology: how do academics demarcate what constitutes ‘proper’ academic knowledge? And to what extent is feminist theory and research recognised as such? I draw on material from an ethnographic study of academia in Portugal to examine the claims that non-feminist scholars make in classrooms and conferences about the epistemic status of feminist scholarship. I observed that feminist work was very commonly described as capable of generating credible and valuable knowledge, (...) but only in some instances and in limited ways. I present examples of these adversative claims (i.e. propositions that express opposition or discrepancy through a ‘but’ or equivalent adversative conjunction) and analyse their structure, content and uses of caricature and humour, showing how epistemic boundaries are drawn in them and how feminist scholarship is positioned in relation to those boundaries. I argue that this boundary-work produces a representation of feminist scholarship as being located partly within, and partly outside, the realm of proper knowledge, a move which I designate as an epistemic splitting of that scholarship. I suggest that this splitting enables and legitimates a selective engagement with feminist work, because it provides non-feminist scholars with a recognised epistemological rationale for taking into account the feminist insights which broadly fit mainstream frameworks, while simultaneously rejecting as epistemologically unsound the feminist critiques of those frameworks.

Although the STS literature on boundary-work recognizes that such work unfolds within a “terrain of uneven advantage” vis-à-vis gender, race, and other inequalities, reflection about that uneven advantage has been strikingly underdeveloped. This article calls for a retheorizing of boundary-work that engages more actively with feminist, critical race, and postcolonial scholarship and examines more systematically the relation between scientific boundary-work, broader structures of sociopolitical inequality, and boundary-workers’ positionality. To demonstrate the need for this retheorization, I analyze ethnographic and interview data (...) on scientific boundary-work in the natural and social sciences in Portugal, showing that scholars’ gender, sexuality, race, ethnicity, and nationality affect the success of their boundary-work. I suggest, therefore, that in unequal societies where credibility is unevenly distributed, the conditions are not in place for some scholars’ boundary-work to work. I draw on Sara Ahmed to argue that we must conceptualize scientific boundary-work as always potentially performative, but not always successfully so, and explicitly interrogate the actual conditions of performativity. Recognizing the links between inequality, embodiment, and non-performativity in scientific boundary-work will enable STS to better understand, and hopefully transform, the relations between contingent struggles over scientificity and entrenched structures of power.

O trabalho discute os fundamentos da educação e as contribuições da filosofia para a educação e para a pedagogia. A análise, em andamento, constitui nossas pesquisas na universidade, investigando as concepções pedagógicas e os pressupostos e fundamentos da educação. O texto de caráter teórico-bibliográfico apresenta uma síntese nas correntes da filosofia da educação, identifica a função social, os limites e as possibilidades desse complexo considerando a especificidade da sociedade de classes. Dessa forma, apoia-se em Saviani (2012, 2013, 2013a), Aranha (1996) (...) e Severino (1995). A educação e a formação humana no modo de produção capitalista perpassam por mecanismos explícitos e implícitos inerentes às teorias educacionais e à práxis educativa determinando as concepções de homem, de mundo e de sociedade.

Considerando as crianças como atores sociais (com voz e ação) competentes para a interpretação do contexto em que se inserem, apresenta-se no presente artigo uma reflexão sobre a sua importância, enquanto sujeitos e participantes na investigação partilhada. Através da participação das crianças como investigadoras em dois estudos de opinião, pretende-se discutir as respetivas possibilidades e limites, enquanto metodologia participativa na Educação Básica. A informação proveniente das crianças forneceu pistas de intervenção aplicadas à escola.

Benzodiazepines and antidepressants have been shown to change responses to unfairness; however, the effects of their combined use on unfairness evaluation are unknown. This study examines the effects of concomitant benzodiazepines and antidepressants long-term use on the evaluation of fair and unfair offers. To analyze behavioral changes on responses to unfairness, we compared the performance of medicated participants and healthy controls in the Ultimatum Game, both in the proposer and in the respondent role. The results showed that long-term psychotropic users (...) had the worse economic strategy by accepting less offers than control subjects. However, in the proposer role, the unfair offers made by participants were similar between groups. The present results suggest that long-term use of psychotropic medication, specifically the combination of benzodiazepines and antidepressants, may increase the sensitivity to unfairness, resulting in higher rejection rates in conditions where this strategy is the most disadvantageous.

Macunaíma: o herói sem nenhum caráter (1928), de Mário de Andrade, é o romance-rapsódia que versa sobre a trajetória de um herói baseado nas lendas indígenas amazônicas e apresentado como autenticamente brasileiro. A paródia se faz presente como intenção em diversas cenas da obra. Todavia, neste trabalho, será tratada a paródia enquanto deformação e transformação (ou imitação) com distanciamento crítico da figura do herói romântico indianista idealizado, que a personagem Peri, de O Guarani (1857), de José de Alencar, encarna. Palavras-chave: (...) Macunaíma. Peri. Herói. Paródia. (shrink)

O que temos em nossas mãos: uma obra acadêmica a mais, uma outra produção intelectual da Professora Maria Rita? Vários motivos nos conduziram a ter diante dos olhos o presente livro desta admirável profissional, educadora competente e mulher cristã que revela não conseguir pensar sua própria existência senão sendo-com tantas-outras-e-outros... É assim que a percebemos, quando no correr destas páginas vislumbramos bem mais do que um texto escrito. É que, ao apresentar com cuidado e rigor científico o fruto de sua (...) pesquisa, Maria Rita entra em diálogo não apenas com os iniciados ou bem experimentados na proposta educacional do Sempre Presente Paulo Freire. Como naqueles bate-papos em que se pode ir e vir com plena liberdade de um assunto para outro, por qualquer ponto que comecemos a leitura somos cativados a uma participação ativa no que estiver sendo dito. Mas, não nos aconteça ter tal "conversa" de forma inadvertida! Aos poucos, diante da clareza com que esta educadora assume suas opções, recebemos o desafio de também nós nos posicionarmos, de abraçarmos o risco da coerência e do que implica escolher um dos lados de nossa cindida sociedade.

The discovery of participation of astrocytes as active elements in glutamatergic tripartite synapses (composed by functional units of two neurons and one astrocyte) has led to the construction of models of cognitive functioning in the human brain, focusing on associative learning, sensory integration, conscious processing and memory formation/retrieval. We have modelled human cognitive functions by means of an ensemble of functional units (tripartite synapses) connected by gap junctions that link distributed astrocytes, allowing the formation of intra- and intercellular calcium waves (...) that putatively mediate large-scale cognitive information processing. The model contains a diagram of molecular mechanisms present in tripartite synapses and contributes to explain the physiological bases of cognitive functions. It can be potentially expanded to explain emotional functions and psychiatric phenomena. (shrink)

Este artigo relaciona a teoria existencialista de Sartre com os aspectos atuais da sociedade do conhecimento atrelados à educação. Para tanto o ser é tomado a partir da sua subjetividade que se estabelece na relação consigo mesmo, com o outro e com o mundo. A partir da trama dessas relações o conhecimento disseminado passa a ser filtrado e orientado entre os sujeitos. Para que haja um resgate à subjetividade, autonomia da consciência humana assentada no desenvolvimento das capacidades cognitivas e afetivas (...) de problematização e apreensão da realidade, no entanto, necessitará de uma formação global com participação crítica baseada na ação e compreensão no mundo.

In Beyond the Anthropological Difference, Matthew Calarco aims both at exposing and interpreting the current theoretical situation regarding animals and at proposing a new way of conceiving human-animal relations, advancing what he calls an ‘ontology of indistinction’. Mimicking Jacques Derrida’s project of decentring philosophy, here Calarco aims at decentring ethics appealing to a serious consideration of the relations between beings as opposed to a search for a ‘primary locus of ethical consideration’ (41). -/- .
