We study the Johansen–Ledoit–Sornette model of financial market crashes :219–255, 2000). On our view, the JLS model is a curious case from the perspective of the recent philosophy of science literature, as it is naturally construed as a “minimal model” in the sense of Batterman and Rice :349–376, 2014) that nonetheless provides a causal explanation of market crashes, in the sense of Woodward’s interventionist account of causation.

Philosophers sometimes claim that economics, and the idealizing strategies it employs, is ultimately unable to provide genuine laws of nature. Therefore, unlike physics, it does not qualify as an actual science. Careful consideration of thermodynamics, a well-developed physical theory, reveals substantial parallels with economic methodology. The corrective account of scientific understanding I offer appreciates these parallels: understanding in terms of efficient performance.

In this paper, I draw a parallel between the stability of physical systems and that of economic ones, such as the US financial system. I argue that the use of equilibrium assumptions is central to the analysis of dynamic behavior for both kinds of systems, and that we ought to interpret such idealizing strategies as footholds for causal exploration and explanation. Our considerations suggest multi-scale modeling as a natural home for such reasoning strategies, which can provide a backdrop for the (...) assessment and prevention of financial crises. Equilibrium assumptions are critical elements of the epistemic scaffolding that make up multi-scale models, which we should understand as a means of constructing explanations of dynamic behavior.

Economists often consult multiple models in order to combat model uncertainty in the face of misspecification. By examining modeling practices at the Bank of England, this paper identifies an important, but underappreciated modeling procedure. Sometimes an idealized model is manipulated to reproduce the results from another distinct auxiliary model, ones which it could not produce on its own. However, this procedure does not involve making the original model “more realistic,” insofar as this means adding in additional causal factors. This suggests (...) that there are ways to make models more representationally adequate that do not involve de-idealization in the straightforward sense. (shrink)

This paper claims that how economists actually treat the consumption function, both theoretically and empirically, seems to be at odds with traditional structural realism. While economics aims to find out the way the world actually is, economic theory – including theoretical staples such as the consumption Euler equation – do not always state literal truths. Yet, such methods persist. Our investigation will reveal that the Euler equation is deployed as part of a realist methodology to identify scale-dominant behaviors. These analyses (...) permit the economist to conduct counterfactual reasoning and sometimes (via policy) to intervene on the world itself; the implication is when this is successful, the economist has uncovered real structure.

In this paper, I discuss the relationship between bodily experiences in dreams and the sleeping, physical body. I question the popular view that dreaming is a naturally and frequently occurring real-world example of cranial envatment. This view states that dreams are functionally disembodied states: in a majority of dreams, phenomenal experience, including the phenomenology of embodied selfhood, unfolds completely independently of external and peripheral stimuli and outward movement. I advance an alternative and more empirically plausible view of dreams as weakly (...) phenomenally-functionally embodied states. The view predicts that bodily experiences in dreams can be placed on a continuum with bodily illusions in wakefulness. It also acknowledges that there is a high degree of variation across dreams and different sleep stages in the degree of causal coupling between dream imagery, sensory input, and outward motor activity. Furthermore, I use the example of movement sensations in dreams and their relation to outward muscular activity to develop a predictive processing account. I propose that movement sensations in dreams are associated with a basic and developmentally early kind of bodily self-sampling. This account, which affords a central role to active inference, can then be broadened to explain other aspects of self- and world-simulation in dreams. Dreams are world-simulations centered on the self, and important aspects of both self- and world-simulation in dreams are closely linked to bodily self-sampling, including muscular activity, illusory own-body perception, and vestibular orienting in sleep. This is consistent with cognitive accounts of dream generation, in which long-term beliefs and expectations, as well as waking concerns and memories play an important role. What I add to this picture is an emphasis on the real-body basis of dream imagery. This offers a novel perspective on the formation of dream imagery and suggests new lines of research. (shrink)

Abstract: Recent experimental research on the 'Knobe effect' suggests, somewhat surprisingly, that there is a bi-directional relation between attributions of intentional action and evaluative considerations. We defend a novel account of this phenomenon that exploits two factors: (i) an intuitive asymmetry in judgments of responsibility (e.g. praise/blame) and (ii) the fact that intentionality commonly connects the evaluative status of actions to the responsibility of actors. We present the results of several new studies that provide empirical evidence in support of this (...) account while disconfirming various currently prominent alternative accounts. We end by discussing some implications of this account for folk psychology. (shrink)

The new field of experimental philosophy has emerged as the methods of psychological science have been brought to bear on traditional philosophical issues. Oxford Studies in Experimental Philosophy will be the place to go to see outstanding new work in the field. It will feature papers by philosophers, papers by psychologists, and papers co-authored by people in both disciplines. The series heralds the emergence of a truly interdisciplinary field in which people from different disciplines are working together to address a (...) shared set of questions. The inaugural volume is roughly structured into four sections. The first three papers focus on recent developments in moral psychology, a topic that has seen lively debate and a great deal of progress over the last decade. The second section highlights three contributions that bring new methods to moral psychology: formal modeling and special populations. The third section brings together four papers that adopt an experimental philosophy approach to novel topics, including intuitive dualism, generics, joint action, and happiness. And the last two papers provide critical and historical context to the development of experimental philosophy. (shrink)

The Character Gap by Christian Miller is an excellent discussion of how the empirical research conducted on virtue bears upon the larger question of whether or not people are virtuous, especially when we consider the question through the lens of a philosophically rigorous account of virtue. His conclusion is that overall people are not virtuous—but then, neither are they vicious. In this commentary, I challenge the latter. I explore two alternative ways of conceiving of vice and utilize a range of (...) empirical findings—on topics ranging from bullying, to sexual assault, to factory farming—to argue that perhaps vice is much more prevalent than Miller believes, a worry that deserves our attention and concern.

Very little research into women farmers in developed countries has been produced by economists, but much of what has been studied by scholars in other disciplines has economic implications. This article reviews such research produced by scholars in all disciplines to explore to what extent women farmers are becoming more equal to men farmers and to suggest further contributions to the literature. As examples, topics that has been widely researched in developing countries but have received almost no attention in developed (...) countries include comparisons of men and women farmers’ productivity and their access to and use of resources. Discoveries in these and other areas will be important not only for their insights into the agricultural industry in developed countries, but also because they will inform, and be informed by, research on women farmers in developing countries.

According to current definitions of civil disobedience, drawn from the work of John Rawls and Carl Cohen, eco-saboteurs are not civil disobedients because their disobedience is not a form of address and/or does not appeal to the public's sense of justice or human welfare. But this definition also excludes disobedience by a wide range of groups, from labor activists to hunt saboteurs, either because they are obstructionist or because they address moral concerns other than justice or the public weal. However (...) earlier definitions of civil disobedience were not so narrow. I review the development of the current definition and the circumstances of its acceptance. I argue that the circumstances which help to explain the attractiveness of the Rawls/Cohen formulations in the 1970s are no longer applicable and that the question of civil disobedience should be revisited. I suggest a wider definition according to which at least some types of eco-sabotage would be civil disobedience. (shrink)

There is growing interest in the processes by which entrepreneurial opportunities are cocreated between entrepreneurs and their stakeholders. The longitudinal case study of de novo firm Wakefield Seafoods seeks to understand the underlying dynamics of phenomena that play out over time as stakeholders emerge and their contributions become essential to the opportunity formation process. The king crab data show that under conditions of uncertainty, characterized by incomplete or missing knowledge, entrepreneurial processes of experimentation, failure, and learning were effective in forming (...) and exploiting an opportunity. Moreover, contrary to existing literature that either emphasizes heroic entrepreneurs or downplays their value, this article shows that both the vision of the entrepreneur and the stakeholder contributions are critical. This detailed examination of process data shows that the cumulative actions made by entrepreneurs in concert with their stakeholders formed an opportunity that coalesced into a new market. (shrink)

The Russian invasion of Ukraine in 2022 was met with condemnation from the European Union and the United States as an "unprovoked and unjustified military aggression" that undermines the liberal international order. However, some international relations scholars, such as John Mearsheimer, argue that Russia had genuine security concerns with regard to Ukraine and that the invasion was a response to the threat of NATO membership for Ukraine. Both liberal and realist perspectives on the invasion rely on the assumption of rational, (...) cost-benefit calculations by actors, but cultural factors and irreconcilable non-material interests may also be at play in shaping the actions and motivations of states. Understanding the cultural and national identity factors at play in the invasion of Ukraine is complex and difficult, but they cannot be ignored in attempting to understand and address the conflict.

Since 1997 there has been a significant increase in the number and percentage of Kansas farmers who are women. Using Reskin and Roos’ model of “job queues and gender queues” I analyze changes in the agricultural industry in Kansas that resulted in more women becoming “principal farm operators” in the state. I find there are three changes largely responsible for women increasing their representation in the occupation: an increase in the demand for niche products, a decrease in the average farm (...) size, and greater societal acceptance of women as farmers. This study adds to the growing literature on women principal farm operators in developed countries, and is among the first to explore why women are becoming a larger percentage of the occupation in the United States.

It is well established that language production and comprehension are influenced by information status, for example, whether information is given, new, topical, or predictable, and many scholars suggest that an important component of information status is keeping track of what information is in common ground, and what is not. Information status affects both speakers' choices and how listeners interpret the speaker's meaning. Although there is a wealth of scholarly work on information status, there is no consensus on the mechanisms by (...) which it is used, and in fact relatively little discussion of the underlying representations and psycholinguistic mechanisms. Moreover, a major challenge to understanding information status is that its effects are notoriously variable. This study considers existing proposals about information status, focusing on two questions: how is it represented; and by what mechanisms is it used? I propose that it is important to consider whether representations and mechanisms can be classified as either explicit or emergent. Based on a review of existing evidence, I argue that information status representations are most likely emergent, but the mechanisms by which they are used are both explicit and emergent. This review provides one of the first considerations of information status processing across multiple domains. (shrink)

Some have argued that Locke's failure to condemn contemporary slavery is best viewed as a personal moral lapse which does not reflect on his political theory. I argue to the contrary.

In this paper I argue that reference to a developmental account of agency can help explain, and in cases also alter, our current practices when it comes to the non-consensual medical treatment of children. It does this through its explanation of how stages of development impact the types of interests we have.

In this paper, I write about nurses of colour who have made significant contributions to nursing, yet are actively ignored in traditional nursing textbooks related to colonized thinking. One consequence of this is that when we think about comparing the disparities of the past to the present day, we see that we have not made much of a difference. The disparity is still huge. I call on all of us as nurses to challenge ourselves to think beyond the box of (...) colonized thought to what we know is true. (shrink)

RÉSUMÉ : J’affirme que les normes sémantiques, y compris les normes mathématiques pour l’addition, sont réelles. Ces normes sont régies par des pratiques sociales d’attribuer aux autres et d’entreprendre soi-même la signification, et cet aspect sociale obscurci l’objectivité des normes. L’attribution par Kripke d’un paradoxe sceptique, quant à la possibilité de suivre une règle, relève d’une conception de la normativité selon laquelle les pratiques sociales sont insuffisantes pour autoriser les normes sémantiques. Or, une conception de la normativité qui prend comme (...) point de départ que les êtres humains font partie du monde, détrône cette idée fausse ainsi que le scepticisme sémantique qu’elle soutien.

An instructor's decision to drop an exam score and to assign a penalty to all class members because no one was willing to identify students who allegedly cheated is described, including how the class members felt about the incident. For the most part, students held the cheaters responsible for their penalties. The instructor received only slightly lower student evaluations, as compared to the 2 other courses she taught that year.

A Psychological Perspective on Folk Moral Objectivism is a thoroughly researched interdisciplinary exploration of the critical role metaethical beliefs play in the way morality functions. Whether or not people are "moral objectivists" is something that deserves much more empirical attention than it has thus far received, not only because it bears upon philosophical claims, but because it is a critical piece of the puzzle of human morality. This book aims to facilitate incorporating the study of metaethical beliefs into existing research (...) programs by providing a roadmap through the theoretical and empirical landscape as it currently exists and evaluating the methodological approaches used thus far. In doing so, it summarizes the key findings-both in terms of metaethical beliefs, and their correlates, causes, and consequences-that have emerged, and explores the value of this area of study for anyone interested in the development, function, causes, and/or consequences of morality.

When education is jointly managed by a workplace and academia, causal mechanisms in the culture, structure and agency of these two contexts may unintentionally generate discourse that conveys conflicting messages for learners regarding some of the priorities of the profession. Using the concepts of culture, structure and agency as they are used in critical realism to analyse the discourse generated in two teaching and learning contexts (a radiography division in a university and a radiography workplace in a large state tertiary (...) academic hospital), this paper attempts (i) to identify possible causal mechanisms that generated discourse concerning the role and value of writing competency for radiographers, such that this discourse possibly influenced learners not to be motivated to improve their writing competency to their lecturers’ satisfaction; and (ii) to suggest what practices and influences might successfully generate an alternative emancipatory discourse. Drawing on Margaret Archer’s (1995) morphogenetic approach, the paper argues that the radiography lecturers have the primary agency to address this unsatisfactory situation, as it is through their interaction – both as a team and with other relevant stakeholders – that an alternative emancipatory discourse may be generated.

Should states use military force for humanitarian purposes? Leading scholars and practitioners provide practical and theoretical answers to this burning question, demonstrating why humanitarian intervention continues to be a controversial issue, not only for the UN, but also for Western states and humanitarian organizations.

In this paper I argue that excising a final end from accounts of virtue does them more harm than good. I attempt to establish that the justification of contemporary virtue ethics suffers if moved this one step too far from the resources in traditional accounts. This is because virtue, as we tend to describe it, rests on an account of practical rationality wherein the role of the final end is integral. I highlight the puzzles that are generated by the ellipsis (...) that is “the role of a final end” in contemporary theories of virtue. The authors of these theories devise ad hoc solutions for these puzzles, puzzles that do not exist for traditional final end-based accounts. Recent critics of virtue ethics have certainly not been satisfied the explanations being offer in lieu of references to a final end. As a remedy, I recommend that the role of a final end be reintroduced in contemporary virtue ethics. I hope to explain that there is nothing to be frightened of and much to be gained. (shrink)

Drawing on in-depth interviews, I analyze how teen fathers talk about the responsibility for having a baby at a young age. In addition to negotiating the stigma often associated with teen pregnancy, teen fathers also confront stereotypes that label them as selfish and uncaring. In telling their stories of “what happened,” they utilize three gendered discourses to deny responsibility for the pregnancy: the feminization of birth control, a discourse of uncontrollable male sexual desire, and love. Their narratives also reveal the (...) ways in which gendered norms can solve some problems while creating others. Aligning themselves with certain notions of masculinity can serve as a resource for denying responsibility for the pregnancy while also signifying their manhood, but these same discourses are also constraining in that they reinforce stereotypes of teen fathers as selfish, even predatory. While these approaches may allow teen fathers to claim masculine identities, they also stigmatize them as the wrong kind of men. In short, teen fathers are not only negotiating the potential stigma of teen pregnancy, they are also negotiating their identities as men. (shrink)

In comparison to activist films with an “in your face” aesthetic, Food, Inc. seems positively tame. Rather than shock viewers with direct images of distasteful, disgusting, immoral, and outrageous practices in the food industry, it provokes and performs physical and moral disgust by its paradoxical (and perhaps quintessentially documentary) combination of proximity and immediacy with distance and delay. This close textual analysis reveals the film’s use of images to defer, deflect, and dodge, in such a way as to emphasize the (...) temporal ‘lag time’ that Sara Ahmed argues is intrinsic to disgust and that connects as well to what Malin Wahlberg calls ‘documentary time.’.

Professions have traditionally treated advocacy as a collective duty, best assigned to professional associations to perform. In North American nursing, advocacy for issues affecting identifiable patients is assigned instead to their nurses. We argue that nursing associations’ withdrawal from advocacy for patient care issues is detrimental to nurses and patients alike. Most nurses work in large institutions whose internal policies they cannot influence. When these create obstacles to good care, the inability of nurses to affect change can result in avoidable (...) distress for them and for their patients. We illustrate this point with a case study: the circumstances of the death of Michael Joseph LeBlanc, an inmate at Kingston Penitentiary Regional Hospital (Ontario). We conclude that patients and their nurses will suffer unnecessarily unless or until nursing associations cease to burden individual nurses with the responsibility for patient advocacy. (shrink)
