Recently, there has been much research into conceptual engineering in connection with feminist inquiry and activism, most notably involving gender issues, but also sexism and misogyny. Our paper contributes to this research by explicating, in a principled manner, a series of other concepts important for feminist research and activism, to wit, feminist political identity terms. More specifically, we show how the popular Conceptual Spaces Framework (CSF) can be used to identify and regiment concepts that are central to feminist research, focusing (...) especially on feminism in France. According to the CSF, concepts can be represented geometrically, as regions in similarity spaces. A particular strength of the CSF framework is its empirically-focused methodology, which allows researchers to infer the boundaries of concepts from empirical data, thus eliminating the need to strongly rely on intuitions about meanings. This is shown to be especially valuable for the explication of concepts relating to feminist political identity, given that the intuitions of feminist scholars and activists about what would appear to be core concepts in the area tend to be poorly aligned or even conflicting. We report the results from an empirical categorization study conducted among French feminists and show how they support the view that the CSF can contribute to both the conceptual engineering project and our understanding of the structure of social reality.

Research on collective emotion spans social sciences, psychology and philosophy. There are detailed case studies and diverse theories of collective emotion. However, experimental evidence regarding the universal characteristics, antecedents and consequences of collective emotion remains sparse. Moreover, current research mainly relies on emotion self-reports, accounting for the subjective experience of collective emotion and ignoring their cognitive and physiological bases. In response to these challenges, we argue for experimental research on collective emotion. We start with an overview of theoretical frameworks to (...) identify a set of three characteristics of collective emotion. Based on research in cognitive and affective sciences, we then examine the corresponding candidate mechanisms. Finally, we highlight outstanding questions, review experimental evidence, and suggest ideas for future experimental research. (shrink)

Non-epistemic values pervade climate modelling, as is now well documented and widely discussed in the philosophy of climate science. Recently, Parker and Winsberg have drawn attention to what can be termed “epistemic inequality”: this is the risk that climate models might more accurately represent the future climates of the geographical regions prioritised by the values of the modellers. In this paper, we promote value management as a way of overcoming epistemic inequality. We argue that value management can be seriously considered (...) as soon as the value-free ideal and inductive risk arguments commonly used to frame the discussions of value influence in climate science are replaced by alternative social accounts of objectivity. We consider objectivity in Longino's sense as well as strong objectivity in Harding's sense to be relevant options here, because they offer concrete proposals that can guide scientific practice in evaluating and designing so-called multi-model ensembles and, in fine, improve their capacity to quantify and express uncertainty in climate projections.

The physical, psychological, and spiritual violence against fat bodies in the US, committed in service of a racist, sexist, classist, and ableist vision of an idealized body size, is death-dealing. This essay develops a theo-ethical vision of fat liberation that rejects the trappings of the “religion of thinness” and celebrates the inherent worth of fat bodies through an incarnational theology that recognizes the image of God in every body size, the presence of body size diversity in creation, and the full (...) inclusion of all body sizes at the eucharistic table.

The reactions that science triggers on the people it studies, describes, or theorises about, can affect the science itself and its claims to knowledge. This phenomenon, which we call reactivity, has been discussed in many different areas of the social sciences and the philosophy of science, falling under different rubrics such as the Hawthorne effect, self-fulfilling prophecies, the looping effects of human kinds, the performativity of models, observer effects, experimenter effects and experimenter demand effects. In this paper we review state-of-the-art (...) research that falls under the remit of the philosophy of reactivity by considering ontological, epistemic and moral issues that reactivity raises. Along the way, we devote special attention to articles belonging to this journal's Topical Collection entitled “Reactivity in the Human Sciences”. (shrink)

Machine learning methods have recently created high expectations in the climate modelling context in view of addressing climate change, but they are often considered as non-physics-based ‘black boxes’ that may not provide any understanding. However, in many ways, understanding seems indispensable to appropriately evaluate climate models and to build confidence in climate projections. Relying on two case studies, we compare how machine learning and standard statistical techniques affect our ability to understand the climate system. For that purpose, we put five (...) evaluative criteria of understanding to work: intelligibility, representational accuracy, empirical accuracy, coherence with background knowledge, and assessment of the domain of validity. We argue that the two families of methods are part of the same continuum where these various criteria of understanding come in degrees, and that therefore machine learning methods do not necessarily constitute a radical departure from standard statistical tools, as far as understanding is concerned.

Convergence of model projections is often considered by climate scientists to be an important objective in so far as it may indicate the robustness of the models’ core hypotheses. Consequently, the range of climate projections from a multi-model ensemble, called “model spread”, is often expected to reduce as climate research moves forward. However, the successive Assessment Reports of the Intergovernmental Panel on Climate Change indicate no reduction in model spread, whereas it is indisputable that climate science has made improvements in (...) its modelling. In this paper, after providing a detailed explanation of the situation, we describe an epistemological setting in which a steady model spread is not doomed to be seen as negative, and is indeed compatible with a desirable evolution of climate models taken individually. We further argue that, from the perspective of collective progress, as far as the improvement of the products of a multi-model ensemble is concerned, reduction of model spread is of lower priority than model independence.

The One Health approach to antimicrobial resistance (AMR) requires stakeholders to contribute to cross-sectoral efforts to improve antimicrobial stewardship (AMS). One Health AMR policy implementation is challenging in livestock farming because of the infrastructural role of antibiotics in production systems. Mitigating AMR may require the development of more stringent stewardship obligations and the future limitation of established entitlements. Drawing on Amatai Etzioni’s compliance theory, regulatory analyses and qualitative studies with stakeholder groups we examine the structural and socio-cultural dimension of antibiotic (...) use and AMS compliance in Australian beef and dairy production. We found a disconnect between how antibiotic use is conceptualised by farmers and the way in which AMS policies construe agricultural AMR risks. Under the umbrella of food safety standards and national-level prescribing restrictions, farmers and veterinarians interact around antibiotic use with different operating logics and compliance mechanisms. These parallel regimes service distinct and sometimes competing common goods of food security and antibiotic preservation. Further reforms to mitigate AMR need to account for the value orientations of different groups and the embeddedness of the constraints imposed by existing systems. Advocacy for greater AMR precaution in agriculture should acknowledge and compensate for erosions in competing common goods and the cost of proposed interventions. (shrink)

Ethics instructors often use cases to help students understand ethics within a corporate context, but we need to know more about the impact a case-based pedagogy has on students’ ability to make ethical decisions. We used a pre- and post-test methodology to assess the effect of using cases to teach ethics in a finance course. We also wanted to determine whether recent corporate ethics scandals might have impacted students’ perceptions of the importance and prevalence of ethics in business, so we (...) used in-depth case studies of several of the major scandals (e.g., Enron, Tyco, Adelphia). Our results are somewhat surprising since studying ethics scandals positively impacts students’ ethical decision making and their perceptions of the ethics of businesspeople. (shrink)

In March of 2012, following a robust activist campaign, Arysta LifeScience withdrew the soil fumigant methyl iodide from the US market, just a little over a year after it had finally been registered for use in California. As a major part of the campaign against registration of the chemical, over 53,000 people, ostensibly acting as citizens rather than consumers, wrote public comments contesting the use of the chemical for its high toxicity. Although these comments had marginal impact on the outcome (...) of the case, these comments are of interest for what they say about public action at a time when efforts to address food and agricultural issues have been dominated by “voting with your fork.” Based on a qualitative textual analysis of approximately 3500 representative comments made available to us, we show that many of those taking action did not abandon consumer subjectivities associated with neoliberal governmentality. By threatening “personal boycotts,” some were acting in their capacity as individual consumers; in invoking their own and their children’s health many more were also acting on behalf of consumers, despite that the chemical in question is applied before strawberries are planted and thus leaves no residues. The emphasis that letter writers gave to their own bodies reinforces the idea that some bodies count more than others and thus reveals a biopolitical sorting. Having consumer lives matter is consequential in light of evidence that consumer concern about pesticides has historically led to formulations and regulations more protective of consumers than workers and neighbors.

We know that reading involves coordination between textual characteristics and visual attention, but research linking eye movements during reading and comprehension assessed after reading is surprisingly limited, especially for reading long connected texts. We tested two competing possibilities: (a) the weak association hypothesis: Links between eye movements and comprehension are weak and short‐lived, versus (b) the strong association hypothesis: The two are robustly linked, even after a delay. Using a predictive modeling approach, we trained regression models to predict comprehension scores (...) from global eye movement features, using participant‐level cross‐validation to ensure that the models generalize across participants. We used data from three studies in which readers (Ns = 104, 130, 147) answered multiple‐choice comprehension questions ~30 min after reading a 6,500‐word text, or after reading up to eight 1,000‐word texts. The models generated accurate predictions of participants' text comprehension scores (correlations between observed and predicted comprehension: 0.384, 0.362, 0.372, ps <.001), in line with the strong association hypothesis. We found that making more, but shorter fixations, consistently predicted comprehension across all studies. Furthermore, models trained on one study's data could successfully predict comprehension on the others, suggesting generalizability across studies. Collectively, these findings suggest that there is a robust link between eye movements and subsequent comprehension of a long connected text, thereby connecting theories of low‐level eye movements with those of higher order text processing during reading.

It is currently common to conceive of the classic methodological individualism–holism debate in level terms. Accordingly, the dispute is taken to concern the proper level of explanations in the social sciences. In this paper, I argue that the debate is not apt to be characterized in level terms. The reason is that widely adopted notions of individualist explanations do not qualify as individual-level explanations because they span multiple levels. I defend this claim relative to supervenience, emergence, and other accounts of (...) the social world as levelled. Moreover, I discuss the consequences of this finding for the ongoing methodological individualism–holism debate. (shrink)

In 2003 the UK National Blood Service introduced a policy of ‘male donor preference’ which involved women’s plasma being discarded following blood collection. The policy was based on the view that data relating to the incidence of Transfusion-Related Acute Lung Injury (TRALI) was linked to transfusion with women’s plasma. While appearing to treat female donors as equal to male donors, exclusion criteria operate after donation at the stage of processing blood, thus perpetuating myths of universality even though only certain ‘extractions’ (...) from women are retained for use in transfusion. Many women in the UK receive a plasma-derived product called Anti-D immunoglobulin which is manufactured from pooled male plasma. This article examines ways in which gender has significance for understanding blood relations, and how the blood economy is gendered. In our study of relations between blood donors and recipients, we explore how gendered bodies are produced through the discursive and material practices within blood services. We examine both how donation policies and the manufacturing and use of blood products produces gendered blood relations. (shrink)

The continued development of General Circulation Models (GCMs) towards increasing resolution and complexity is a predominantly chosen strategy to advance climate science, resulting in channelling of research and funding to meet this aspiration. Yet many other modelling strategies have also been developed and can be used to understand past and present climates, to project future climates and ultimately to support decision-making. We argue that a plurality of climate modelling strategies and an equitable distribution of funding among them would be an (...) improvement on the current predominant strategy for informing policy making. To support our claim, we use a philosophy of science approach to compare increasing resolution and complexity of General Circulation Models with three alternate examples: the use of machine learning techniques, the physical climate storyline approach, and Earth System Models of Intermediate Complexity. We show that each of these strategies prioritises a particular set of methodological aims, among which are empirical agreement, realism, comprehensiveness, diversity of process representations, inclusion of the human dimension, reduction of computational expense, and intelligibility. Thus, each strategy may provide adequate information to support different specific kinds of research and decision questions. We conclude that, because climate decision-making consists of different kinds of questions, many modelling strategies are all potentially useful, and can be used in a complementary way. (shrink)

Arts and Humanities in Higher Education, Volume 21, Issue 2, Page 198-219, April 2022. This article presents playfulness as an emerging approach to learning in higher education that emphasises the arts and humanities across disciplines. The article is based on a qualitative, hermeneutical literature review in light of educational culture in higher education. The literature review indicates that playful approaches to learning stand in opposition to educational cultures that focus on rapidness and student performance. However, an educational culture of play (...) is about to establish itself, and this culture of play emphasises creativity in learning and human flourishing in education, perspectives that are connected to arts and humanities. The main findings cultures of time, performance and play lead to several questions about societal, institutional, and organisational educational culture, and regarding approaches to teaching, learning, humanity and society. The main contribution of this article is that a focus on playfulness offer the field of arts and humanities new possibilities in future education. (shrink)

The assessments issued by the Intergovernmental Panel on Climate Change (IPCC) aim to provide policy-makers with an objective source of information about the various causes of climate change, the projected consequences for the environment and human affairs, and the options for adaptation and mitigation. But what, in this context, is meant by ‘objective’? In practice, in an effort to address internal and external criticisms, the IPCC has regularly revised its methodological procedures; some of these procedures seem to meet the requirements (...) of objectivity, at least as understood in a specific sense, but the relationship between objectivity and value-neutrality requires further investigation. The aim of this paper is to offer an appropriate philosophical account of objectivity, reconcilable with the fact that the IPCC is not value-free. I argue that Sandra Harding’s notion of strong objectivity is particularly well suited to this goal, and I examine the extent to which the current IPCC procedures match her account. (shrink)

This paper is dedicated to the first universities and mendicant schools, where thousands of students began to converge during the thirteenth century. Logic played an unpreceded role in basic and higher education. A “Parisian logical model” of education was shaped at the University of Paris, adopted by mendicant Orders in their schools of logic, diffused in all disciplines, and progressively spread in Southern Europe. Medieval education became heavily based upon logical, and even “logician” practices, with the “syllogization” of exegetical, disputational, (...) and evaluation practices.The notion of logical skill conveniently captures this unique situation for the discipline of logic, as well as the way medieval thinkers conceived of logic as a universal, transdisciplinary method, a natural operation of the mind, a modality of knowledge, the very form of teaching and graduating, a “habitus,” a technique and a science.The divisions of Aristotelian logic, the “artificial logic,” were for the first time naturalized and projected on the very structure of human mind, which was thereby “logicalized” and ascribed a “natural logic.” A strong anthropological dimension was bestowed on logic. The discipline of logic was deemed a necessary instrument in the philosophical “perfection” and the Christian “reparation” of man as an intellectual creature by a group of logically skilled, professional philosophers and theologians, whereas men deprived of logical education were described as “logically disabled,” and stuck into inferior forms of humanity.The world of medieval intellectual elites displayed a variety of social uses of logic, beyond academic circles, especially in the performance of pastoral duties. The possible historical records of the social usefulness of logic are explored: for students, the majority in medieval universities, who left university without a degree, but with a solid logical education, for ordinary mendicant friars, dedicated to preaching and confession, who frequented logical schools, and for members of the parish clergy sent to the faculties of arts.

Virtue and the Moral Life brings together distinguished philosophers and theologians with younger scholars of consummate promise to produce ten essays that engage both academics and students of ethics.

Nous montrons à cet égard combien les débats métaphysiques de la première modernité sont inséparables d’un certain nombre d’engagements éthiques et politiques. En particulier, les préjugés de nos penseurs sur les capacités intellectuelles des non-Européens ne sont pas extérieurs (...) à ce débat mais en sont, au contraire, le moteur. (shrink)

I wonder why women philosophers, once recognized, too often seem to drop from the intellectual radar screen or, at least, to drop mainly to the land of footnotes and bibliographies. I consider one distinguished moral philosopher, Elizabeth Lane Beardsley, both to highlight her philosophical contributions and as a case study that suggests more widespread problems in recognizing t5he work of female philosophers and ensuring their rightful place in our professional dialogue. I consider sociological and professional factors which might partially explain (...) why work by women philosophers has not always received the attention in the professional dialogue it seems to deserve. I conclude with some modest suggestions about the efforts that we can make to address these problems, including the organization of readings for our own courses, the sources consulted for our own research and writing, and the preservation of rec rods of meetings and other public gatherings that recognize women philosophers.

When E. M. Forster published the novel Howards End in 1910, it was at the height of ‘the inheritance society’, and the gulf between rich and poor was great and problematic; a fact that Forster was very well aware of. Yet in spite of this, the main character in Howards End, Margaret Schlegel, is a financially independent rentier living off of the wealth of her ancestors, and her wealth increases when she is named the ‘spiritual heir’ of Ruth Wilcox and (...) thus inherits the house of Howards End. In this study, I argue that Forster shifts the focus from inherited money to inherited values in order to pardon a society of great inequality. Drawing on an aristocratic principle, Forster thus deals with inheritance as an inalienable and spiritual subject rather than as a legal and economic one. (shrink)

L'empirisme transcendantal élaboré par Gilles Deleuze n'est pas le fruit du hasard : il résulte de lectures critiques et d'un véritable remaniement de concepts, notamment dans ses monographies des années cinquante et soixante. Or on lit généralement les œuvres de maturité de Deleuze sans trop s'attarder sur ces premiers écrits. De même, la question de la subjectivité dans son œuvre est souvent laissée au second plan, et l'on constate dans la littérature secondaire des opinions diamétralement opposées quant au statut du (...) sujet chez Deleuze. Le présent ouvrage reconstruit la notion deleuzienne de subjectivité à partir des premières monographies que le philosophe a consacrées à Hume, Kant, Nietzsche et Bergson. Il confronte les œuvres de ces auteurs aux monographies de Deleuze, et réarticule les concepts de la période de 'Différence et répétition' (singularités, habitudes, champ transcendantal, etc.) autour des questions sur la genèse et le statut de la subjectivité."--Page 4 of cover.

This essay looks at the important, but often neglected, contribution that self‐interpretation makes to emotional self‐knowledge. We engage in acts of self‐interpretation when (A) we try to understand what it is that we are feeling, or, relatedly, what it is that we ought to be feeling. On such occasions, we draw upon social and personal narratives as well as on the emotional conceptual repertoires at our disposal. We also engage in acts of self‐interpretation when (B) we try to ascertain the (...) meaning or significance of an emotion, treating it as a datum, or piece of evidence, upon which to make inferences or further Interpretations. Although we often seem to have first‐person privileged access to our mental states, the third‐person strategy of self‐interpretation can be a valuable source of self‐knowledge. I focus here upon the role that self‐interpretation plays in providing us with knowledge about our emotional experiences. (shrink)

In this article, the authors operationalize the intersection of gender and race in survey research. Using quantitative data from the Multi-City Study of Urban Inequality, they investigate how gender/racial stereotypes about African Americans affect Whites’ attitudes about two types of affirmative action programs: job training and education and hiring and promotion. The authors find that gender/racial prejudice towards Black women and Black men influences Whites’ opposition to affirmative action at different levels than negative attitudes towards Blacks as a group. Prejudice (...) toward Black women has a larger effect on Whites’ policy preferences than does prejudice toward Black men or Blacks in general. In future research, survey methodologists should develop better intersectional measures to further document these gender/racial attitudes. (shrink)

Taking up Lemke’s (2000) critical questions of how moments add up to lives and social life, we articulate theoretical and methodological frameworks for _perezhivanie_ and becoming, challenging binaries that splinter entangled flows of _perezhivanie_ into frozen categories. Working from a flat CHAT notion of assemblage to develop an ontology of moments, we stress consequentiality, arguing it emerges in intersections of embodied intensities (not only affective, but also indexical, intra-actional, and historic), the dispersed bio-cultural-historical weight of artifacts and practices, and dialogic (...) resonances across moments. Methodologically, we take an ethico-onto-epistemological perspective to systematically study perezhivanie. The bio-ecological model of rich environments (centered around meaningful complexity, agency, and individual optimization) offers both a key framework for understanding becoming and a design framework for transdisciplinary realizations of ethico-onto-epistemological practice. We illustrate these frameworks with examples from four research projects: a university physics lab group doing and writing an experiment, a former pastor managing bipolar disorder and rejecting faith, a sustained social justice education program at a university, and intersections of aging policies, media representations, and stroke survival in Brazil. Finally, we argue that an ontology of moments centered on consequentiality can illuminate _perezhivanie's_ relationship to becoming and that the model of enriched environments offers metrics to assess and design environments.

A growing body of research has suggested that high levels of family functioning—often measured as positive parent–child communication and low levels of parental stress—are associated with stronger cognitive development, higher levels of school engagement, and more successful peer relations as youth age. The COVID-19 pandemic has brought tremendous disruption to various aspects of daily life, especially for parents of young children, ages 3–5, who face isolation, disconnection, and unprecedented changes to how they engage and socialize. Fortunately, both youth and parent (...) brains are plastic and receptive to change. Resilience research shows that factors such as engaging in acts of kindness, developing trusting relationships, and responding compassionately to the feelings of others can help lay new neural pathways and improve quality of life. Yet, little research has investigated the effects of brain healthy parental practices of kindness with pre-school aged children. The current study examines whether an interactive, parent–child kindness curriculum can serve as a potentiator for brain health as measured by resilience and child empathy levels. During a peak of the pandemic, mother participants between the ages of 26–46 completed questionnaires on parental resilience levels and parent-reported child empathic pro-social behaviors before and after engaging in a 4 weeks online, self-paced, kindness curriculum. Half of the group received additional brain health education explaining the principles of neuroplasticity, empathy, perspective taking, and resiliency. Mothers in both groups showed increased resilience and reported higher levels of empathic behavior in their child after completing the curriculum. There was no significant difference between groups. Comparison of mean resilience levels during COVID-19 to pre-pandemic general means indicated that mothers are reporting significantly lower levels of resilience as well as decreased empathetic behaviors in their children. These results support the notion that kindness is a powerful brain health booster that can increase resilience and empathy. This research study was timely and relevant for parents in light of the myriad of stresses brought about by the ongoing COVID-19 pandemic. There are broader public health implications for equipping individuals with tools to take a proactive and preventative approach to their brain health. (shrink)

Cetaceans show high cognitive abilities and strong social bonds. Their primary sensory modality to communicate and sense the environment is acoustics. Research on their echolocation and social vocalizations typically uses visual and tactile systems adapted from research on primates or birds. Such research would benefit from a purely acoustic communication system to better match their natural capabilities. We argue that a full duplex system, in which signals can flow in both directions simultaneously is essential for communication research. We designed and (...) implemented a full duplex system to acoustically interact with cetaceans in the wild, featuring digital echo-suppression. We pilot tested the system in Arctic Norway and achieved an echo suppression of 18 dB. We discuss the limiting factors and how to improve the echo suppression further. The system enabled vocal interaction with the underwater acoustic scene by allowing experimenters to listen while producing sounds. We describe our motivations, then present our pilot deployment and give examples of initial explorative attempts to vocally interact with wild orcas and humpback whales. (shrink)

In this paper we assess the explanatory role of idealizations in ‘design explanations’, a type of functional explanation used in biology. In design explanations, idealizations highlight which factors make a difference to phenomena to be explained: hypothetical, idealized, organisms are invoked to make salient which traits of extant organisms make a difference to organismal fitness. This result negates the view that idealizations serve only pragmatic benefits, and complements the view that idealizations highlight factors that do not make a difference. This (...) analysis in particular strengthens the perspective that idealizations are means to highlight difference making factors, and identifies a novel, more direct role for idealizations in doing so. It thus offers a novel argument why in some explanatory contexts idealizations are in-eliminable. (shrink)
