The phenomenon of ambiguity aversion, in which risky gambles with known probabilities are preferred over ambiguous gambles with unknown probabilities, has been thoroughly documented in adults but never measured in children. Here, we use two distinct tasks to investigate ambiguity preferences of children (8- to 9-year-olds) and a comparison group of adults (19- to 27-year-olds). Across three separate measures, we found evidence for significant ambiguity aversion in adults but not in children and for greater ambiguity aversion in adults compared to (...) children. As ambiguity aversion in adults has been theorized to result from a preference to bet on the known and avoid the unfamiliar, we separately measured familiarity bias and found that children, like adults, are biased towards the familiar. Our findings indicate that ambiguity aversion emerges across the course of development between childhood and adolescence, while a familiarity bias is already present in childhood. (shrink)

In this thesis I argue that the tradition of political philosophy which follows in John Rawls's footsteps is obligated to concern itself not only with the realizability, but also with the realization, of justice. Although Rawls himself expresses a commitment only to the former of these, I argue that the roles which he assigns to political philosophy require him to take on the further commitment to realization. This is because these roles are meant to influence not only political philosophers, but (...) the citizens of the wider community as well. The realistically utopian role, which I take to be the central one, requires political philosophy to inspire in that population a hope which I argue that realizability alone cannot provide. Given the deep revisions regarding the political nature of justice as fairness which Rawls made on the basis of realizability concerns, I argue that his theory must in this case be committed to a similar revision. The hope which political philosophy is meant to provide is simply not realizable until the discipline concerns itself centrally with the task of realization. (shrink)

This paper presents the evaluation of the alpha version of a gamified tool called Call for Papers: The Game (CfP:TG), specially designed for teaching scientific writing in the training of future engineers. A non-probabilistic convenience sampling was carried out with the participation of engineering students from a Peruvian public university. The short version of the user experience questionnaire (UEQ) was applied, and usability was qualitatively evaluated. The main results indicate that the Pragmatic Quality of CfP:TG is in the neutral range (...) with a value of 0.729, and the Hedonic Quality receives a positive evaluation with a value of 1.089.

Winner of the Premio Iberoamericano Book Award in 1997 What form does the crisis of modernity take in Latin America when societies are politically demobilized and there is no revolutionary agenda in sight? How does postmodern criticism reflect on enlightenment and utopia in a region marked by incomplete modernization, new waves of privatization, great masses of excluded peoples, and profound sociocultural heterogeneity? In _No Apocalypse, No Integration _Martín Hopenhayn examines the social and philosophical implications of the triumph of neoliberalism and (...) the collapse of leftist and state-sponsored social planning in Latin America. With the failure of utopian movements that promised social change, the rupture of the link between the production of knowledge and practical intervention, and the defeat of modernization and development policy established after World War II, Latin American intellectuals and militants have been left at an impasse without a vital program of action. Hopenhayn analyzes these crises from a theoretical perspective and calls upon Latin American intellectuals to reevaluate their objects of study, their political reality, and their society’s cultural production, as well as to seek within their own history the elements for a new collective discourse. Challenging the notion that strict adherence to a single paradigm of action can rescue intellectual and cultural movements, Hopenhayn advocates a course of epistemological pluralism, arguing that such an approach values respect for difference and for cultural and theoretical diversity and heterodoxy. This essay collection will appeal to readers of sociology, public policy, philosophy, cultural theory, and Latin American history and culture, as well as to those with an interest in Latin America’s current transition.

In the Netherlands, as in many other nations, the government has proposed the use of a contact-tracing app as a means of helping to contain the spread of the corona virus. The discussion about the use of such an app has mostly been framed in terms of a tradeoff between privacy and public health. This research statement presents an analysis of the Dutch public debate on Corona-apps by using the framework of Orders of Worth by Boltanski and Thévenot (...) (1991). It argues that this framework can help us to move beyond the dichotomy of privacy vs. public health by recognizing a plurality of conceptions of the common good in the debate about contact-tracing apps. This statement presents six orders of worth present in the Dutch debate:civic, domestic, vitality, market, industrialandproject,and argues that the identification of which common goods are at stake will contribute to discussions about the use of this technology from a standpoint with a richer ethical perspective.

In this article the impact of the Covid-19 virus will be used as a lens to read this Isaianic text. The collective threat of the corona-virus causes trauma on societies and communities on different levels: psychological, physical, existential and communal trauma. Isaiah 7:18–25 also tells us of an historic event which caused extreme trauma to its audience. Verse 18 describes the arrival of the Assyrian army. The prophet compares the Assyrian hosts to the flies “in the rivers of Egypt”, (...) and to the bees in Assyria; that is to say, the invaders will be the innumerable and speedy warriors of the Assyrian king. This portrayal is expanded stating that the flies and the bees will swarm all over the land, penetrate every corner and crack and it will be impossible to get rid of them. The plague of “flies” in the metaphor represents the large numbers, while the “bees” are clearly the aggressive and terrifying ones in this metaphor. Just as the Assyrians, who are about to appear as an unwanted and troublesome multitude of flies and bees from which Ahaz will be unable to free himself and his kingdom, the Covid-19 virus is causing havoc and wreckage to societies all over the world. Contribution: This article reflects theologically on the immense psychological and existential damage of trauma caused by the terrifying and laming fear this virus has on the mental well-being of a society. The theological reflections will engage with a biblical text which also reflects on the traumatic effects of threat and fear that lamed a society. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Minutes of the Annual General Meeting 2023Cornelis de Waal, Editor-in-Chief, Richard Kenneth Atkins, André De Tienne, Director and General Editor, and Elizabeth Cooke[as approved on January 17, 2024]The Annual General Meeting of the Charles S. Peirce Society was held in conjunction with the Eastern Division Meeting of the APA on January 5, 2023, at the Sheraton Le Centre, Montréal, Quebec. Rosa Maria Mayorga chaired the meeting and called (...) it to order at 12:38 p.m.1. Moment of SilenceThe annual meeting began with a moment of silence in memory of Peirce scholars who passed away in the last year.2. Approval of Minutes of the 2022 MeetingMinutes of the 2022 Annual General Meeting had been posted online. Copies were also distributed at the annual meeting. Rosa Maria Mayorga asked for a motion to approve the minutes. James Liszka so moved and Fabienne Forster seconded. The minutes were approved unanimously.3. Report from the Executive CommitteeRichard Kenneth Atkins submitted the following report.The Executive Committee Meeting was held virtually via email. All members of the Executive Committee were contacted and responded regarding the agenda and items.Agenda Items(A) Non-profit Status Update:On December 5, 2022, we received notification from the IRS that we have been legally approved as a public non-profit foundation.(B) Funding for Scholarship:Every year, we set aside a certain amount of funding for scholarship, usually 2/3rds of the year's income. This includes the $1,000 set aside for the Peirce Essay prize. Atkins reported that the income this past year was $6,597.06. 2/3rds of that is $4,400. Atkins requested that that amount of money be set aside for funding for scholarship, with which the committee unanimously agreed.(C) Next Year's AGM:Atkins proposed that we continue to hold our annual conference in conjunction with the E-APA in New York, NY, especially as this keeps us in line with the calendar year which is also our fiscal year as a nonprofit. The committee unanimously agreed. [End Page 118](D) Any Other Business:Cornelis de Waal suggested that we add to the agenda for the annual business meeting a moment of silence to commemorate Peirce scholars who passed this year. The Executive Committee unanimously agreed.4. Report from the Transactions of the Charles S. Peirce SocietyCornelis de Waal submitted the following report on behalf of the Transactions of the Charles S. Peirce Society. Richard Kenneth Atkins read the report on his behalf.During the 2022 calendar year we produced four issues of the Transactions. We encountered some problems with the first issue, because the printer suffered a ransomware attack. This apparently wreaked havoc with their system and caused significant delay in the completion of the issue.Likely due to the (after) effects of the pandemic, quality submissions to the journal were down significantly, both in the Peirce segment and in the non-Peirce segment of the journal. In addition, there was a significant drop in book reviews. The latter led to the resignation of our long-term book review editor, Henrik Rydenfelt. For the last two months I have been taking over for him, and I'm first-hand experiencing some of the challenges, even including publishers simply not following through on requests for books. We did, though, publish a book symposium on James Liszka's Charles Peirce on Ethics, Esthetics and the Normative Sciences, and we have another book symposium forthcoming on Chris Voparil's Reconstructing Pragmatism: Richard Rorty and the Classical Pragmatists. Besides a number of excellent papers on Peirce, we published some very nice papers in American philosophy. The latter include an extensive portrait of Edwin Bissell Holt, a discussion of the use of the term pragmatism in 18th century Germany, the first English translation of two texts by Wilhelm Jerusalem, as well as work on George Santayana, Jonathan Edwards, and Emily Dickinson.With Henrik gone, the editorial team is now down to Robert Lane and me (hopefully briefly returning to the traditional Robin-Hare setup). I'll be attending the upcoming SAAP meeting in Denver, and Bob is planning to attend as well... (shrink)

Marking a ground-breaking moment in the debate surrounding bodies and "body politics," Elizabeth Grosz's Space, Time and Perversion contends that only by resituating and rethinking the body will feminism and cultural analysis effect and unsettle the knowledges, disciplines and institutions which have controlled, regulated and managed the body both ideologically and materially. Exploring the fields of architecture, philosophy, and--in a controversial way--queer theory, Grosz shows how these fields have conceptually stripped bodies of their specificity, their corporeality, and the vestigal (...) traces of their production as bodies. Her tour de corpe investigates the work of Michel Foucault, Teresa de Lauretis, Gilles Deleuze, Judith Butler and Alphonso Lingis. Grosz considers their work by examining the ways in which the functioning of bodies transforms understandings of space and time, knowledge and desire. Begining with an exposition of the epistemological implications of bodily and sexual difference, Grosz examines the effects such knowledge have on the reception of meaning. She looks at the relationship between the knowledge of difference and the way that knowledge validates, affirms, avows and valorizes subjects. Grosz then extends this analysis to an investigation of the relationship between space, time, bodies and the spatial "arts" such as architecuture, urban planning and geography. In the last section, Grosz moves toward a radical consideration of bodies and their relationship to transgression and perversity. Controversially showing the ways in which "queer" theory fails to offer a truly transformative conception of bodies and their politics, Grosz finds "queer" a reactive category "which sees itself in opposition to a straight norm and thus defines itself in terms of this norm." Consequentially, "queer" theory inherits the acceptance of an entire range of sexual practices, without "asking what they share and without taking into account the profound tension that may exist among these practices." Grosz's Space, Time and Perversity is a diverse and incisive collection of essays from a renowned feminist philosopher. (shrink)

Background The opioid epidemic has enabled rapid and unsurpassed use of big data on people with opioid use disorder to design initiatives to battle the public health crisis, generally without adequate input from impacted communities. Efforts informed by big data are saving lives, yielding significant benefits. Uses of big data may also undermine public trust in government and cause other unintended harms. Objectives We aimed to identify concerns and recommendations regarding how to use big data on opioid use in ethical (...) ways. Methods We conducted focus groups and interviews in 2019 with 39 big data stakeholders who had interest in or knowledge of the Public Health Data Warehouse maintained by the Massachusetts Department of Public Health. Results Concerns regarding big data on opioid use are rooted in potential privacy infringements due to linkage of previously distinct data systems, increased profiling and surveillance capabilities, limitless lifespan, and lack of explicit informed consent. Also problematic is the inability of affected groups to control how big data are used, the potential of big data to increase stigmatization and discrimination of those affected despite data anonymization, and uses that ignore or perpetuate biases. Participants support big data processes that protect and respect patients and society, ensure justice, and foster patient and public trust in public institutions. Recommendations for ethical big data governance offer ways to narrow the big data divide, enact shared data governance, cultivate public trust and earn social license for big data uses, and refocus ethical approaches. Conclusions Using big data to address the opioid epidemic poses ethical concerns which, if unaddressed, may undermine its benefits. Findings can inform guidelines on how to conduct ethical big data governance and in ways that protect and respect patients and society, ensure justice, and foster patient and public trust in public institutions.

The vivid, dramatic images of distant stars and galaxies taken by the Hubble Space Telescope have come to define how we visualize the cosmos. In their immediacy and vibrancy, photographs from the Hubble show what future generations of space travelers might see should they venture beyond our solar system. But their brilliant hues and precise details are not simply products of the telescope's unprecedented orbital location and technologically advanced optical system. Rather, they result from a series of deliberate decisions made (...) by the astronomers who convert raw data from the Hubble into spectacular pictures by assigning colors, adjusting contrast, and actively composing the images, balancing the desire for an aesthetically pleasing representation with the need for a scientifically valid one. In Picturing the Cosmos, Elizabeth A. Kessler examines the Hubble's deep space images, highlighting the remarkable resemblance they bear to nineteenth-century paintings and photographs of the American West and their invocation of the visual language of the sublime. Drawing on art history and the history of science, as well as interviews with astronomers who work on the Hubble Heritage Project, Kessler traces the ways that the sublime, with its inherent tension between reason and imagination, not only forms the appearance of the images, but also operates on other levels. The sublime informs the dual expression—numeric and pictorial—of digital data and underpins the relevance of the frontier for a new era of exploration performed by our instruments rather than our bodies. Through their engagement with the sublime the Hubble images are a complex act of translation that encourages an experience of the universe as simultaneously beyond humanity's grasp and within the reach of our knowledge. Strikingly illustrated with full-color images, this book reveals the scientific, aesthetic, and cultural significance of the Hubble pictures, offering a nuanced understanding of how they shape our ideas—and dreams—about the cosmos and our places within it.

This book explores the tradition of the 'science of man' in French medicine of the era 1750-1850, focusing on controversies about the nature of the 'physical-moral' relation and their effects on the role of medicine in French society. Its chief purpose is to recover the history of a holistic tradition in French medicine that has been neglected because it lay outside the mainstream themes of modern medicine, which include experimental, reductionist, and localistic conceptions of health and disease. Professor Williams also (...) challenges existing historiography, which argues that the 'anthropological' approach to medicine was a short-term by-product of the leftist politics of the French Revolution. This work argues instead that the medical science of man long outlived the Revolution, that it spanned traditional ideological divisions, and that it reflected the shared aim of French physicians, whatever their politics, to claim broad cultural authority in French society.

Face perception, perhaps the most highly developed visual skill in humans, is mediated by a distributed neural system in humans that is comprised of multiple, bilateral regions. We propose a model for the organization of this system that emphasizes a distinction between the representation of invariant and changeable aspects of faces. The representation of invariant aspects of faces underlies the recognition of individuals, whereas the representation of changeable aspects of faces, such as eye gaze, expression, and lip movement, underlies the (...) perception of information that facilitates social communication. The model is also hierarchical insofar as it is divided into a core system and an extended system. The core system is comprised of occipitotemporal regions in extrastriate visual cortex that mediate the visual analysis of faces. In the core system, the representation of invariant aspects is mediated more by the face-responsive region in the fusiform gyrus, whereas the representation of changeable aspects is mediated more by the face-responsive region in the superior temporal sulcus. The extended system is comprised of regions from neural systems for other cognitive functions that can be recruited to act in concert with the regions in the core system to extract meaning from faces.

This article is an interview with Elizabeth Povinelli, by Mathew Coleman and Kathryn Yusoff. It addresses Povinelli’s approaches to ‘geontologies’ and ‘geontopower’, and the discussion encompasses an exploration of her ideas on biopolitics, her retheorization of power in the current conditions of late liberalism, and the situation of the inhuman within philosophical and anthropological economies. Povinelli describes a mode of power that she calls geontopower, which operates through the governance of Life and Nonlife. The interview is accompanied by a (...) brief contextualizing introduction.

Though emotion conveys memory benefits, it does not enhance memory equally for all aspects of an experience, nor for all types of emotional events. In this review, I outline the behavioral evidence for arousal's focal enhancements of memory and describe the neural processes that may support those focal enhancements. I also present behavioral evidence to suggest that these focal enhancements occur more often for negative experiences than for positive ones. This result appears to arise because of valence-dependent effects on the (...) neural processes recruited during episodic encoding and retrieval, with negative affect associated with increased engagement of sensory processes, and positive affect leading to enhanced recruitment of conceptual processes.

This paper is a critical examination of Lonergan’s notion of moral conversion. Conversion in general is described as a mode of self-transcendence and distinguished from development. Then moral conversion is contrasted with the two other basic forms of conversion, intellectual and religious. Next, I propose that there are two distinct moments of moral conversion: a negative moment of rational compunction, which is more Kantian in nature, and a positive moment of passionate transcendence, which is consonant with Scheler’s value ethics. I (...) draw on philosophical accounts of the initial awakening of moral consciousness, and argue that it is possible to make this first movement yet fail to make the second movement. (shrink)

This paper reflects on certain working assumptions of Husserlian phenomenological practice, using an investigation of interkinaesthetic affectivity as an example. I suggest that in some cases, Husserl’s “stratificational” model should be replaced with the notion of the ongoing dynamic efficacy of mutually co-founding, interpenetrating, and interfunctioning moments-“through”-which experience proceeds. Finally, I relate the latter model to Patočka’s call for a genuine integration of the three movements of embodied human life.

Process models are valuable conceptual tools to help in understanding the approaches to value creation in social enterprises. This teaching case illustrates the application of a process model about creating, building, and sustaining a social enterprise with a mission to provide clean water to communities in need. The social enterprise generates revenue in support of community water projects and works with community stakeholders in different locations throughout the world to provide sustainable clean water solutions. The case study uses primary data (...) from semi-structured interviews, direct observations of a community project, and archival sources to demonstrate application of the process model. The study shows how the social enterprise developed as a promising idea; was implemented through an operating model with resources to support social impact; and continues to build and evolve while guided by the social mission. The paper concludes with a discussion and teaching note on ways to use the case for educational purposes to enhance learning about the social value creation process. (shrink)

This Husserlian transcendental-phenomenological investigation of interkinaesthetic affectivity first clarifies the sense of affectivity that is at stake here, then shows how Husserl’s distinctive approach to kinaesthetic experience provides evidential access to the interkinaesthetic field. After describing several structures of interkinaesthetic-affective experience, I indicate how a Husserlian critique of the presupposition that we are “psychophysical” entities might suggest a more inclusive approach to a biosocial plenum that includes all metabolic life.

Astronomy has a long tradition of translating data into different visual representations and scholars have noted a division between ‘pretty pictures’ and scientific images. A series of drawings and engravings of M51 derived from Lord Rosse’s observations at Birr Castle and Hubble Space Telescope images of the same object offer an opportunity to examine shifts in the object’s representation within a given period, as well as over the long history of observing it. This demonstrates both the consistent interest of astronomy (...) in structure and improved resolution, as well as the subjective treatment of light and color. Furthermore, while the distinction between ‘pretty pictures’ and scientific images offers a starting point for analyzing the translations within a given period, the line between the two blurs, suggesting the complexity of aesthetic choices within astronomical images.Keywords: Hubble Space Telescope; M51; Whirlpool Galaxy; Lord Rosse; Astronomical images.

In _Between Gaia and Ground_ Elizabeth A. Povinelli theorizes the climatic, environmental, viral, and social catastrophe present as an ancestral catastrophe through which that Indigenous and colonized peoples have been suffering for centuries. In this way, the violence and philosophies the West relies on now threaten the West itself. Engaging with the work of Glissant, Deleuze and Guattari, Césaire, and Arendt, Povinelli highlights four axioms of existence—the entanglement of existence, the unequal distribution of power, the collapse of the event (...) as essential to political thought, and the legacies of racial and colonial histories. She traces these axioms' inspiration in anticolonial struggles against the dispossession and extraction that have ruined the lived conditions for many on the planet. By examining the dynamic and unfolding forms of late liberal violence, Povinelli attends to a vital set of questions about changing environmental conditions, the legacies of violence, and the limits of inherited Western social theory. _Between Gaia and Ground_ also includes a glossary of the keywords and concepts that Povinelli has developed throughout her work.

Current work on hooking up—or casual sexual activity on college campuses—takes an individualistic, “battle of the sexes” approach and underestimates the importance of college as a classed location. The authors employ an interactional, intersectional approach using longitudinal ethnographic and interview data on a group of college women’s sexual and romantic careers. They find that heterosexual college women contend with public gender beliefs about women’s sexuality that reinforce male dominance across both hookups and committed relationships. The four-year university, however, also reflects (...) a privileged path to adulthood. The authors show that it is characterized by a classed self-development imperative that discourages relationships but makes hooking up appealing. Experiences of this structural conflict vary. More privileged women struggle to meet gender and class guidelines for sexual behavior, placing them in double binds. Less privileged women find the class beliefs of the university foreign and hostile to their sexual and romantic logics. (shrink)

Prior research has examined value antecedents to sustainable consumption, including religious or cultural values. We bridge together these usually separated bodies of literature to provide an ethically-based examination of both religious and cultural values in one model to understand what drives sustainable consumption as well as outcomes on consumer well-being. In doing so, we also fulfill calls for more research on socio-demographic antecedents to ethical consumption, particularly in the domain of sustainable consumption. We examine this relationship using data from the (...) religiously and culturally diverse country of Singapore, collected from a door-to-door, representative sample utilizing numerous quality control techniques. Our path analysis and logical follow-up tests reveal that both religious and cultural values influence sustainable consumption, and then sustainable consumption positively influences consumer well-being. Implications are provided for consumer ethics, business’ ethical practices, and belief congruence theory. (shrink)

'Since the middle of the twentieth century,' writes Elizabeth Johnson, 'there has been a renaissance of new insights into God in the Christian tradition. On different continents, under pressure from historical events and social conditions, people of faith have glimpsed the living God in fresh ways. It is not that a wholly different God is discovered from the One believed in by previous generations. Christian faith does not believe in a new God but, finding itself in new situations, seeks (...) the presence of God there. Aspects long-forgotten are brought into new relationships with current events, and the depths of divine compassion are appreciated in ways not previously imagined.' This book sets out the fruit of these discoveries. The first chapter describes Johnson's point of departure and the rules of engagement, with each succeeding chapter distilling a discrete idea of God. Featured are transcendental, political, liberation, feminist, black, Hispanic, interreligious, and ecological theologies, ending with the particular Christian idea of the one God as Trinity. >.

The risk of executing innocent persons is a decisive objection to the institution of capital punishment in the United States. Consequentialist arguments for the death penalty are inconclusive at best; the strongest justification is a retributive one. However, this argument is seriously undercut if a significant risk of executing the innocent exists. Any criminal justice system carries the risk of punishing innocent persons, but the punishment of death is unique and requires greater precautions. Retributive justifications for the death penalty are (...) grounded in respect for innocent victims of homicide; but accepting serious risks of mistaken executions demonstrates disrespect for innocent human life. United States Supreme Court decisions of the 1990’s illustrate the existence of serious risk and suggest some explanations for it. (shrink)

In typical statistical learning studies, researchers define sequences in terms of the probability of the next item in the sequence given the current item (or items), and they show that high probability sequences are treated as more familiar than low probability sequences. Existing accounts of these phenomena all assume that participants represent statistical regularities more or less as they are defined by the experimenters—as sequential probabilities of symbols in a string. Here we offer an alternative, or possibly supplementary, hypothesis. Specifically, (...) rather than identifying or labeling individual stimuli discretely in order to predict the next item in a sequence, we need only assume that the participant is able to represent the stimuli as evincing particular similarity relations to one another, with sequences represented as trajectories through this similarity space. We present experiments in which this hypothesis makes sharply different predictions from hypotheses based on the assumption that sequences are learned over discrete, labeled stimuli. We also present a series of simulation models that encode stimuli as positions in a continuous two‐dimensional space, and predict the next location from the current location. Although no model captures all of the data presented here, the results of three critical experiments are more consistent with the view that participants represent trajectories through similarity space rather than sequences of discrete labels under particular conditions.
