Among critical responses to the perceived perils of the industrial food system, the food sovereignty movement offers a vision of radical transformation by demanding the democratic right of peoples “to define their own agriculture and food policies.” At least conceptually, the movement offers a visionary and holistic response to challenges related to human and environmental health and to social and economic well-being. What is still unclear, however, is the extent to which food sovereignty discourses and activism interact with and affect (...) the material and social realities of the frequently low-income communities of color in which they are situated, and whether they help or hinder pre-existing efforts to alleviate hunger, overcome racism, and promote social justice. This research and corresponding paper addresses those questions by examining food justice and food sovereignty activism in the city of New Orleans since Hurricane Katrina as understood by both activists and community members. I argue, using post-Katrina New Orleans as a case study, that food projects initiated and maintained by white exogenous groups on behalf of communities of color risk exacerbating the very systems of privilege and inequality they seek to ameliorate. This paper argues for a re-positioning of food justice activism, which focuses on systemic change through power analyses and the strategic nurturing of interracial alliances directed by people residing in the communities in which projects are situated.

Several studies show that healthcare professionals need to communicate inter-professionally in order to manage ethical difficulties. A model of clinical ethics support inspired by Habermas’ theory of discourse ethics has been developed by our research group. In this version of CES sessions healthcare professionals meet inter-professionally to communicate and reflect on ethical difficulties in a cooperative manner with the aim of reaching communicative agreement or reflective consensus. In order to understand the course of action during CES, the aim of this (...) study was to describe the communication of value conflicts during a series of inter-professional CES sessions. Ten audio- and video-recorded CES sessions were conducted over eight months and were analyzed by using the video analysis tool Transana and qualitative content analysis. The results showed that during the CES sessions the professionals as a group moved through the following five phases: a value conflict expressed as feelings of frustration, sharing disempowerment and helplessness, the revelation of the value conflict, enhancing realistic expectations, seeing opportunities to change the situation instead of obstacles. In the course of CES, the professionals moved from an individual interpretation of the situation to a common, new understanding and then to a change in approach. An open and permissive communication climate meant that the professionals dared to expose themselves, share their feelings, face their own emotions, and eventually arrive at a mutual shared reality. The value conflict was not only revealed but also resolved. (shrink)

O objetivo deste ensaio é apresentar uma análise sucinta dos reflexos dos argumentos de Durkheim sobre educação no corpo da Lei de Diretrizes e Bases daEducação Nacional nº 9394/96. Arquiteto de um paradigma clássicopara a sociologia, que se irradia alimentando outros paradigmas de teóricos degrande envergadura, que o sucederam, Émile Durkheim conferiu àSociologia uma base empírica, com métodos próprios de investigação, demonstrando que os fatos sociais – seu objeto de estudo – teriam características próprias, que os distinguiriam dos estudados pelas (...) demais ciências. Considero que fiz uma aproximação tímida, a partir de leituras preliminares, que revelaram um universo teórico complexo, com uma vasta gama de conceitos enredados, e além disso um fascínio que torna difícil interromper as leituras. O texto reflete leituras das obras Educação e Sociologia e Divisão do Trabalho Social, bem como de comentadores, como Quintaneiro e Aron .The purpose of this essay is to present a brief analysis of the reflections ofDurkheim's arguments about education in the Law of Directives and Basis ofNational Education nº 9394/96. It was with Emile Durkheim , the architect of a classic paradigm for sociology, that radiates to otherparadigms of major theorists, who succeeded him, that sociology came to be considered a science, with an empirical basis and its own methods of research; he showed that its object of study, social facts, would have characteristics that distinguish it from those studied by other sciences. I believe that I done a timid approach, from first readings, that revealed a complex theoretical universe, with awide range of concepts, and a fascination that makes it difficult to stop the readings. The referential reflects the readings of Education and Sociology and The Division of Labour in Society and commentators, as Quintaneiro and Aron. (shrink)

A large literature suggests that the organization of words in semantic memory, reflecting meaningful relations among words and the concepts to which they refer, supports many cognitive processes, including memory encoding and retrieval, word learning, and inferential reasoning. The co‐activation of related items has been proposed as a mechanism by which semantic knowledge influences cognition, and contemporary accounts of semantic knowledge propose that this co‐activation is graded—that it depends on how strongly related the items are in semantic memory. Prior research (...) with adults yielded evidence supporting this prediction; however, there is currently no evidence of graded co‐activation early in development. This study provides the first evidence that in children the co‐activation of related items depends on their relational strength in semantic memory. Participants (N = 84, age range: 3–9 years) were asked to identify a target (e.g., bone) amid distractors. Children's responses were slowed down by the presence of a related distractor (e.g., puppy) relative to unrelated distractors (e.g., flower)—suggesting that children co‐activated related items upon hearing the name of the target. Importantly, the degree of this co‐activation was predicted by the strength of the target–distractor relation, such that distractors more strongly related to the targets slowed down children to a larger extent. These findings have important implications for understanding how organized semantic knowledge affects other cognitive processes across development. (shrink)

This photo-essay, entitled 'Our Stories: Cartography of a Conflict', is born from the fieldwork carried out in the scope of the research 'Past, Present and Future in the Voice of Women and Girls Affected by the Conflict in Cabo Delgado: A Feminist Analysis', as a way of naming and disseminating the diversity of voices of displaced women, and broadening the visibility of their stories, which have very often been reduced to statistics. The aim of this article is to share their (...) perceptions and demands, their stories and journeys in search of security and possible horizons for their re-existence. This photo-essay shows that women displaced and affected by the conflict need to be named, singularised in their aspirations, needs and struggles. Their life stories are the reason for this work. It is their pain and resilience, their desires, their invisible and visible powers, their strategies for rebuilding their lives, families and communities that we want to make known. Their voices need to be heard, read, understood and placed at the centre of all governmental and civil society interventions for reconstruction, humanitarian response and peacebuilding in Cabo Delgado. Each woman participating in this photo-essay has chosen to share her story and her face, and has decided how to be photographed and represented, with the desire that somehow their trajectories become sources of direct knowledge to guide the paths to Peace in the province. They want to be known and recognised in their dignity, in their determination and perseverance, as well as in their deepest needs. The story of each woman shared in this article is a local and national reference to build a nonviolent future in Mozambique. (shrink)

Public engagement is one of the fundamental pillars of the European programme for research and innovation _Horizon 2020_. The programme encourages engagement that not only fosters science education and dissemination, but also promotes two-way dialogues between scientists and the public at various stages of research. Establishing such dialogues between different groups of societal actors is seen as crucial in order to attain epistemic as well as social desiderata at the intersection between science and society. However, whether these dialogues can actually (...) help attaining these desiderata is far from obvious. This paper discusses some of the costs, risks, and benefits of dialogical public engagement practices, and proposes a strategy to analyse these argumentative practices based on a three-tiered model of epistemic exchange. As a case study, we discuss the phenomenon of vaccine hesitancy, arguably a result of suboptimal public engagement, and show how the proposed model can shed new light on the problem. (shrink)

I examine the theory of consequentia of the medieval logician, John Buridan. Buridan advocates a strict commitment to what we now call proposition-tokens as the bearers of truth-value. The analysis of Buridan's theory shows that, within a token-based semantics, amendments to the usual notions of inference and consequence are made necessary, since pragmatic elements disrupt the semantic behaviour of propositions. In my reconstruction of Buridan's theory, I use some of the apparatus of modern two-dimensional semantics, such as two-dimensional matrices and (...) the distinction between the context of formation and the context of evaluation of utterances.

Neste artigo pretendemos compreender se, e de que forma, o cinema pode servir a uma cosmopoética do pensamento decolonial. Para tanto, nos apoiaremos em alguns conceitos dos estudos decoloniais, que buscam atualizar a tradição crítica do pensamento latino-americano a partir da problematização do pensamento hegemônico, oferecendo novas releituras histórias e novas possibilidades de produção dos saberes. A perspectiva decolonial opera fornecendo novos horizontes para o pensamento, promovendo uma ecologia dos modos de saber e conhecimento não reconhecidos pelas epistemologias dominantes. Assim, (...) buscamos entender a potência cosmopoética do cinema e como ele pode contribuir, dentro dos espaços de educação, como alternativa epistemológica para o pensamento decolonial. (shrink)

A contemporary serious lack of scientific knowledge by the general public and many decision-makers is now quite perceptible, both globally and in Portugal. Living in a science-driven technological world filled with scientific illiteracy is dangerous and a path toward disaster. Recent years brought a fairly strong global movement promoting the so-called “alternative therapy” that also affected Portugal. I propose an evidence-based ethics reflection and argumentation, both encompassing the global and the specific Portuguese reality. I debate the specific arguments used in (...) favour of alternative therapies, demonstrating the inherent fallacies of thought, deliberate manipulation of words and concepts, and the dire consequences for global and local health politics by following this line of biased reasoning.

As higher education teachers we undertook a self-study research focused on emotional education, during two school years. The analysis of the students’ portfolios and the teachers’ fieldnotes provide evidence to problematize some tensions and challenges identified along the process, namely for integrating personal, cultural and institutional dimensions, facing the unpredictability of a participative process and opening new paths. Students valued the work centred on their own goals, the building of a personal learning project in conjunction with a class collective project, (...) the relational practices based on an ethics of care, the diversity of mindfulness and meditation proposals, amongst others.

BackgroundThis study is part of a major study about difficulties in communicating ethical problems within and among professional groups working in hemodialysis care. Describing experiences of ethically difficult situations that induce a troubled conscience may raise consciousness about ethical problems and thereby open the way to further reflection.The aim of this study was to illuminate the meanings of being in ethically difficult situations that led to the burden of a troubled conscience, as narrated by physicians working in dialysis care.MethodA phenomenological (...) hermeneutic method was used to analyze the transcribed narrative interviews with five physicians who had varying lengths of experience in nephrology.ResultsThe analysis shows that physicians working in hemodialysis care suffered from a troubled conscience when they felt torn by conflicting demands and trapped in irresolution. They faced ethical dilemmas where they were forced to make crucial decisions about life or death, or to prioritize when squeezed between time restraints and professional and personal demands. In these ethical dilemmas the physicians avoided arousing conflicts, were afraid of using their authority, were burdened by moral responsibility and felt devalued and questioned about their way of handling the situation. The findings point to another way of encountering ethical dilemmas, being guided by their conscience. This mean sharing the agony of deciding how to act, being brave enough to bring up the crucial problem, feeling certain that better ways of acting have not been overlooked, being respected and confirmed regarding decisions made.ConclusionThe meanings of being in ethically difficult situations that led to the burden of a troubled conscience in those working in hemodialysis care, indicate the importance of increasing the level of communication within and among various professional groups - to transform being burdened by a troubled conscience into using conscience as a guide - in situations where no way of solving the problem seems to be good.

BackgroundMoral distress has been described as an emotionally draining condition caused by being prevented from providing care according to one’s convictions. Studies have described the impact of moral distress on healthcare professionals, their situations and experiences. The Measure of Moral Distress for Healthcare Professionals (MMD-HP) is a questionnaire that measures moral distress experienced by healthcare professionals at three levels: patient, system and team. The aim of this project was to translate and make a cultural adaption of the MMD -HP to (...) the Swedish context.MethodsThe questionnaire comprises 27 items, rated according to frequency and intensity on a five-point Likert scale (0–4). The procedure for translating MMD-HP followed WHO guidelines (2020). These entailed a forward translation from English to Swedish, a back translation, expert panel validation, pretesting and cognitive face-to-face interviews with 10 healthcare professionals from various professions and healthcare contexts.ResultsThe Swedish version of MMD-HP corresponds essentially to the concept of the original version. Parts of some items’ had to be adjusted or removed in order to make the item relevant and comprehensible in a Swedish context. Overall, the cognitive interviewees recognized the content of the items which generally seemed relevant and comprehensible.ConclusionThe Swedish version of MMD-HP could be a useful tool for measuring moral distress among healthcare professionals in a Swedish healthcare context.

Anthropogenic changes in the biosphere, driven mainly by human cultural habits and technological advances, are altering the direction of evolution on Earth, with ongoing and permanent changes modifying uncountable interactions between organisms, the environment, and humankind itself. While numerous species may go extinct, others will be favored due to strong human influences. The Bio-Evolutionary Anthropocene hypothesizes that directly or indirectly human-driven organisms, including alien species, hybrids, and genetically modified organisms, will have major roles in the evolution of life on Earth, (...) shifting the evolutionary pathways of all organisms through novel biological interactions in all habitats. We anticipate that, in future scenarios, novel organisms will be continuously created, and contemporary native organisms with no obvious economic use will decline—while anthropogenic-favored and novel organisms will spread. The Bio-Evolutionary Anthropocene hypothesis therefore predicts that humankind and novel organisms will interact within a strong evolutionary bias that will lead to unexpected, and probably irreversible, outcomes for the evolution of life on our planet.

Explication is the conceptual cornerstone of Carnap’s approach to the methodology of scientific analysis. From a philosophical point of view, it gives rise to a number of questions that need to be addressed, but which do not seem to have been fully addressed by Carnap himself. This paper reconsiders Carnapian explication by comparing it to a different approach: the ‘formalisms as cognitive tools’ conception. The comparison allows us to discuss a number of aspects of the Carnapian methodology, as well as (...) issues pertaining to formalization in general. We start by introducing Carnap’s conception of explication, arguing that there is a tension between his proposed criteria of fruitfulness and similarity; we also argue that his further desideratum of exactness is less crucial than might appear at first. We then bring in the general idea of formalisms as cognitive tools, mainly by discussing the reliability of so-called statistical prediction rules, i.e. simple algorithms used to make predictions across a range of areas. SPRs allow for a concrete instantiation of Carnap’s fruitfulness desideratum, which is arguably the most important desideratum for him. Finally, we elaborate on what we call the ‘paradox of adequate formalization’, which for the Carnapian corresponds to the tension between similarity and fruitfulness. We conclude by noting that formalization is an inherently paradoxical enterprise in general, but one worth engaging in given the ‘cognitive boost’ it affords as a tool for discovery. (shrink)

BackgroundMoral distress is a problem and negative experience among health-care professionals. Various instruments have been developed to measure the level and underlying reasons for experienced moral distress. The moral distress thermometer (MDT) is a single-tool instrument to capture the level of moral distress experienced in real-time.AimThe aim of this study was to translate the MDT and adapt it to the Swedish cultural context.Research designThe first part of this study concerns the translation of MDT to the Swedish context, and the second (...) part the psychometric testing of the Swedish version.Participants and research context89 healthcare professionals working at a hospital in northern Sweden participated. Convergent validity was tested between MDT and Measure of Moral Distress-Healthcare Professionals (MMD-HP), and construct validity was tested by comparing MDT scores among healthcare professionals. MDT was compared with responses to the final questions in MMD-HP. One-way ANOVA, Welch’s ANOVA, Games–Howell post-hoc test and Pearson’s correlation analysis were done.Ethical considerationsThe study was approved by the Swedish Ethics Review Authority (dnr 2020-04120) in accordance with Helsinki Declaration.ResultsThe translated Swedish version of MDT was described as relevant to capture the experience of moral distress. The mean value for MDT was 2.26, with a median of 2 and a mode value of 0. The result showed moderate correlations between the MDT and MMD-HP total scores. There was a significant difference when comparing MDT and healthcare professionals who had never considered leaving their present position with those who had left and those who had considered leaving but had not done so, with the latter assessing significantly higher moral distress.ConclusionThe MDT is an easily available instrument useful as an extension to MMD-HP to measure the real-time experience of moral distress among healthcare professionals in a Swedish context.

Argumentation is important for sharing knowledge and information. Given that the receiver of an argument purportedly engages first and foremost with its content, one might expect trust to play a negligible epistemic role, as opposed to its crucial role in testimony. I argue on the contrary that trust plays a fundamental role in argumentative engagement. I present a realistic social epistemological account of argumentation inspired by social exchange theory. Here, argumentation is a form of epistemic exchange. I illustrate my argument (...) with two real-life examples: vaccination hesitancy, and the undermining of the credibility of traditional sources of information by authoritarian politicians. (shrink)

Background Ethics communication has been described as a pedagogical form, promoting development of ethical competence among nursing students. The ‘one to five method’ was developed by this research group as a tool for facilitating ethical communication in groups among healthcare professionals but has not yet been evaluated. Aim To explore post-graduate nursing students’ experiences of practicing ethical communication in groups Research design The study design is qualitative. Participants and research context The study comprised 12 nursing students on a post-graduate course (...) for Registered Nurses focusing on palliative care. After education the students engaged as participants and facilitators in ethics communication in groups, with support from the ‘one to five method’. Data were derived from the students written reflections and subjected to thematic analysis. Ethical considerations The study was performed in accordance with the ethical standards in the 2013 Helsinki Declaration and approved by the Ethics Committee of the Medical Faculty at Umeå University Results An overall theme was identified, ‘being supported to achieve a democratic dialogue concerning ethical problems’ and five themes, related to each step of the ‘one to five method’. The themes concerned: putting the experience of an ethical dilemma into words; being confirmed by shared emotions; defining the value conflict using ethical principles; expressing virtues of empathy and raised awareness; jointly finding various action approaches. Discussion Regular ethics communication in groups encourages nursing students to actively seek understanding and clarification of ethically difficult situations. Conclusions The results indicate that ethics communication in groups could be a way of developing virtues during education. Interventions using the ‘one to five method’ need to be further studied among student groups from other healthcare contexts. (shrink)

The term Open Society was rigorously presented by Bergson in Les Deux Sources de la morale et de la religion (1932), but it was Karl Popper's The Open Society and Its Enemies (1945) that made the expression famous. It was under the influence of this last approach and not Bergson's that the term came to be used practically as a synonym for democracy or a scientific, rational, free, tolerant, inclusive, pluralist and humanist social order. The term has come to encompass (...) nearly every core value held by the free world; but what it gained in breadth it lost in depth, approaching common sense at the expense of its philosophical value. This article, therefore, tries to revert this conceptual impoverishment, returning to Bergson's original perspective, in dialogue with Karl Popper's rationalist and critical reflection. (shrink)

It is well known that reductio ad absurdum arguments raise a number of interesting philosophical questions. What does it mean to assert something with the precise goal of then showing it to be false, i.e. because it leads to absurd conclusions? What kind of absurdity do we obtain? Moreover, in the mathematics education literature number of studies have shown that students find it difficult to truly comprehend the idea of reductio proofs, which indicates the cognitive complexity of these constructions. In (...) this paper, I start by discussing four philosophical issues pertaining to reductio arguments. I then briefly present a dialogical conceptualization of deductive arguments, according to which such arguments are best understood as a dialogue between two participants—Prover and Skeptic. Finally, I argue that many of the philosophical and cognitive difficulties surrounding reductio arguments are dispelled or at least further clarified once one adopts a dialogical perspective.

Since at least the 1980s, the role of adversariality in argumentation has been extensively discussed within different domains. Prima facie, there seem to be two extreme positions on this issue: argumentation should never be adversarial, as we should always aim for cooperative argumentative engagement; argumentation should be and in fact is always adversarial, given that adversariality is an intrinsic property of argumentation. I here defend the view that specific instances of argumentation are adversarial or cooperative to different degrees. What determines (...) whether an argumentative situation should be primarily adversarial or primarily cooperative are contextual features and background conditions external to the argumentative situation itself, in particular the extent to which the parties involved have prior conflicting or else convergent interests. To further develop this claim, I consider three teloi that are frequently associated with argumentation: the epistemic telos, the consensus-building telos, and the conflict management telos. I start with a brief discussion of the concepts of adversariality, cooperation, and conflict in general. I then sketch the main lines of the debates in the recent literature on adversariality in argumentation. Next, I discuss the three teloi of argumentation listed above in turn, emphasizing the roles of adversariality and cooperation for each of them. (shrink)

In the final section, I offer brief considerations on an alternative account of reasoning, where the focus is on how sociocultural environments may tune the social production and evaluation of arguments.

We report three experimental studies of reasoning with double conditionals, i.e. problems based on premises of the form: If A then B. If B then C. where A, B, and C, describe everyday events. We manipulated both the logical structure of the problems, using all four possible arrangements (or “figures” of their constituents, A, B, and C, and the believability of the two salient conditional conclusions that might follow from them, i.e. If A then C, or If C then A. (...) The experiments showed that with figures for which there was a valid conclusion, the participants more often, and more rapidly, drew the valid conclusion when it was believable than when it was unbelievable. With figures for which there were no valid conclusions, the participants tended to draw whichever of the two conclusions was believable. These results were predicted by the theory that reasoning depends on constructing mental models of the premises. (shrink)

El presente artículo explora las percepciones sobre la existencia de los filósofos medievales musulmanes Avicena (m. 1037) y Averroes (m. 1198), cuyas obras se encuentran muy próximas a la filosofía de Aristóteles. Además de la influencia aristotélica, que caló en toda la filosofía islámica medieval, Avicena y Averroes estuvieron inspirados por la teología islámica, conocida en árabe como Kalam. La distinción entre esencia y existencia es uno de los más fundamentales y controvertidos aspectos de la filosofía de Avicena junto a (...) su aseveración de que la existencia es un accidente. Averroes, en cambio, concibe de forma radicalmente diferente la existencia, identificándola con los seres existentes más que considerarla como algo en sí misma. Con la traducción al latín de los trabajos de metafísica de Avicena en el siglo XII, su distinción prosiguió modelando el debate sobre la existencia en la filosofía escolástica medieval y más allá. Este artículo evalúa el significado de la distinción en la crítica tanto de Avicena como de Averroes. Al explicar sus concepciones, radicalmente distintas, de la existencia se establece un contacto con posteriores discusiones concernientes a la misma, como, por ejemplo, la cuestión de si la existencia es un predicado, en la edad moderna.
