We provide an overview of a transdisciplinary project about sustainable forest management under climate change. Our project is a partnership with members of the Menominee Nation, a Tribal Nation located in northern Wisconsin, United States. We use immersive virtual experiences, translated from ecosystem model outcomes, to elicit human values about future forest conditions under alternative scenarios. Our project combines expertise across the sciences and humanities as well as across cultures and knowledge systems. Our management structure, governance, and leadership behaviors have (...) both fostered and constrained our work and must be continuously responsive to changing group dynamics. Our project presents opportunities for substantial contributions to society, including insights and knowledge about complementary ways of knowing, skills training, and professional development, and opportunities for reflexive learning about effective transdisciplinary, translational, and transformative scientific processes.

In his target article, Yarkoni prescribes descriptive research as a potential antidote for the generalizability crisis. In our commentary, we offer four guiding principles for conducting descriptive research that is generalizable and enduring: prioritize context over control; let naturalistic observations contextualize structured tasks; operationalize the target phenomena rigorously and transparently; and attend to individual data.

Given the growing public concern and attention placed on cases of research misconduct, government agencies and research institutions have increased their efforts to develop and improve ethics education programs for scientists. The present study sought to assess the impact of these increased efforts by sampling empirical studies published since the year 2000. Studies published prior to 2000 examined in other meta-analytic work were also included to provide a baseline for assessing gains in ethics training effectiveness over time. In total, this (...) quantitative review consisted of 66 empirical studies, 106 ethics courses, 150 effect sizes, and 10,069 training participants. Overall, the findings indicated that ethics instruction resulted in sizable benefits to participants and has improved considerably within the last decade. A number of specific findings also emerged regarding moderators of instructional effectiveness. Recommendations are discussed for improving the development, delivery, and evaluation of ethics instruction in the sciences. (shrink)

Predictive modeling in education draws on data from past courses to forecast the effectiveness of future courses. The present effort sought to identify such a model of instructional effectiveness in scientific ethics. Drawing on data from 235 courses in the responsible conduct of research, structural equation modeling techniques were used to test a predictive model of RCR course effectiveness. Fit statistics indicated the model fit the data well, with the instructional characteristics included in the model explaining approximately 85% of the (...) variance in RCR instructional effectiveness. Implications for using the model to develop and improve future RCR courses are discussed. (shrink)

Requirements for business ethics education and organizational ethics trainings mark an important step in encouraging ethical behavior among business students and professionals. However, the lack of specificity in these guidelines as to how, what, and where business ethics should be taught has led to stark differences in approaches and content. The present effort uses meta-analytic procedures to examine the effectiveness of current approaches across organizational ethics trainings and business school courses. to provide practical suggestions for business ethics interventions and research. (...) Thus, the primary questions driving this research are as follows: what course characteristics moderate the effectiveness of ethics instruction?, and have ethics education and training efforts improved? Findings suggest that professional, focused, and workshop-based training programs are especially effective for improving business ethics. However, results also reveal considerable problems with many of the criteria used to evaluate the effectiveness of business ethics interventions. Practical suggestions for course design and evaluation in business ethics efforts are discussed along with future research needs. (shrink)

ABSTRACT Researchers have increasingly acknowledged that affect plays a role in ethical decision making. However, the impact that specific affective states may have on the expression of decision biases in the context of ethical dilemmas has received limited empirical attention. To address this, the present effort examined the impact of happy and sad affective states on biases in ethical decision making. In an online experiment, undergraduate students read short stories that either induced happy, sad, or relaxed affective states, followed by (...) a covert measure of three types of biases held to inhibit ethical decision making. Results demonstrated that happy affective states increased the expression of regulation biases, and sad affective states increased the expression of simplification biases, compared to relaxed affective states. Implications are discussed for advancing research on ethical decision making and reducing unethical behavior in organizations. (shrink)

The paper studies the impact of informational ambiguity on behalf of informed traders on history-dependent price behaviour in a model of sequential trading in financial markets. Following Chateauneuf et al., we use neo-additive capacities to model ambiguity. Such ambiguity and attitudes to it can engender herd and contrarian behaviour, and also cause the market to break down. The latter, herd and contrarian behaviour, can be reduced by the existence of a bid-ask spread.

Increased investment in ethics education has prompted a variety of instructional objectives and frameworks. Yet, no systematic procedure to classify these varying instructional approaches has been attempted. In the present study, a quantitative clustering procedure was conducted to derive a typology of instruction in ethics education. In total, 330 ethics training programs were included in the cluster analysis. The training programs were appraised with respect to four instructional categories including instructional content, processes, delivery methods, and activities. Eight instructional approaches were (...) identified through this clustering procedure, and these instructional approaches showed different levels of effectiveness. Instructional effectiveness was assessed based on one of nine commonly used ethics criteria. With respect to specific training types, Professional Decision Processes Training and Field-Specific Compliance Training appear to be viable approaches to ethics training based on Cohen’s d effect size estimates. By contrast, two commonly used approaches, General Discussion Training and Norm Adherence Training, were found to be considerably less effective. The implications for instruction in ethics training are discussed. (shrink)

There is an argument (first presented by Fitch), which tries to show by formal means that the anti-realistic thesis that every truth might possibly be known, is equivalent to the unacceptable thesis that every truth is actually known (at some time in the past, present or future). First, the argument is presented and some proposals for the solution of Fitch's Paradox are briefly discussed. Then, by using Wehmeier's modal logic with subjunctive marks (S5*), it is shown how the derivation can (...) be blocked if one respects adequately the distinction between the indicative and the subjunctive mood. Essentially, this proposal amounts to the one by Edgington which was formulated with the help of the actuality-operator. Finally it is shown how the criticisms by Williamson against Edgington can be answered by the formulation of a new conception of possible knowledge that \alpha (thereby \alpha being in the indicative mood and thus referring to the actual world). This conception is based on the concept of same de re knowledge in different possible worlds. (shrink)

Hobbs (2010) introduced ‘clause-internal coherence’ (CIC) to describe inferences in, e.g., ‘A jogger was hit by a car,’ where the jogging is understood to have led to the car-hitting. Cohen & Kehler (2021) argue that well-known pragmatic tools cannot account for CIC, motivating an enrichment account familiar from discourse coherence research. An outstanding question is how to compositionally derive CIC from coherence relations. This paper takes strides in answering this question. It first provides experimental support for the existence of CIC (...) via offline evidence that attributive (non-)deverbal adjectives can trigger the same causal inferences within clauses that their predicative counterparts can trigger across clauses, albeit more weakly. To explain the experimental results, we use tools in Segmented Discourse Representation Theory (SDRT), which allows us to show that causal inferences can be derived in various ways, depending on whether deverbal adjectives are used attributively or predicatively. If the former, they are presupposition triggers and the coherence relations Elaboration/Continuation compete with Background; if the latter, Explanation/Result compete with Background. These different competitions -- cashed out in terms of interaction between default axioms -- correlate with the difference in the relative salience of the causal inferences. (shrink)

As the prevalence of conflict and fragility continue to rise around the world, research is increasingly heralded as a solution. However, current ethical guidelines for working in areas suffering from institutional and social fragility, insecurity or violent conflict have been heavily critiqued as highly abstract; focussed only on data collection; detached from the realities of academia in the Global South; and potentially extractive. This article seeks to respond to that assessment by spotlighting some of the most prevalent challenges researchers face (...) in the pursuit of ethical working practices. It explores the material and epistemic injustices that often shape and underpin research structures and relationships in these contexts. The paper draws on the authors’ experiences of research in conflict-affected and fragile contexts over the last fifteen years and on workshop discussions with researchers based in fragile and conflict-affected contexts conducted in Amman, Bogotá and Dhaka in 2019-2020. The paper works from the premise that achieving ethical research in fragile spaces is not dependent solely on activity at the site of research, but also on decisions made across the entire ecosystem of a research project. It therefore interrogates the full research landscape, from funding models, to research design, to dissemination plans and ethical gatekeeping. The paper critically reflects on inequities in the processes of knowledge production about conflict and fragility and the key ethical challenges that researchers encounter. It highlights the need for further guidance, support and accountability to ensure ethical research practices. (shrink)

Aristotle maintains that defining nous requires first defining its activity, which requires first having considered its objects, intelligible beings. This chapter is about the nature of these objects: what about them makes them intelligible? My principal proposals will be that what makes them intelligible is that they are separate or unmixed, and that because, insofar as they are intelligible, they are, in their essence, activity. I am not unaware that this makes it sound as though Aristotle takes intelligibility to consist (...) in some kind of nous. But he himself virtually says as much, when he claims that nous is the form of its objects (lit. εἶδος εἰδῶν); besides it is a result he is committed to by the doctrines that nous is intelligible and that there is something that intelligible objects all are in common; for the alternative, as he himself says, is to suppose that nous “will have something mixed-in, which makes it intelligible just like the rest.” The challenge, then, is not to steer clear of this result, but to make sense of it. My proposal will be that the key lies in realizing that and why Aristotle thinks intelligibility is a creature of nous. (shrink)

Aristotle's thesis in "Physics" I 8 is that a certain old and familiar problem about coming to be can only be solved with the help of the new account of the "principles" he has developed in "Physics" I 7. This is a strong thesis and the literature on the chapter does not quite do it justice; specifically, as things now stand we are left wondering why Aristotle should have found this problem so compelling in the first place. In this paper (...) I develop an interpretation which (I hope) will help to remedy this. I believe that Aristotle's problem about coming to be depends on a certain principle to the effect that "nothing can become what it already is" (it is this that is supposed to explain why τὸ ὄν cannot come to be ἐξ ὄντος -- cf. 191a30). The main innovation of the interpretation developed here is its suggestion that we understand this principle as a principle about kinds. So understood, the principle does not make the comparatively trivial point that nothing can become any individual it already is, but rather the more powerful and substantive point that nothing can become any kind of thing it already is. I argue that this is a point which Aristotle himself accepts and that this is why the problem about coming to be raises serious difficulties for him. I also discuss Aristotle's proposed solutions to this problem, explaining how each draws on his new account of the principles and why each is required for any full resolution of the difficulties the problem raises. In this way I hope to show how the interpretation developed here does justice to the very strong thesis with which Aristotle begins "Physics" I 8. I conclude briefly and somewhat speculatively with a suggestion as to why Aristotle might accept the principle on which I have suggested the problem turns. (shrink)

Aristotle introduces Physics I as an inquiry into principles; in this paper I ask where he argues for the position he reaches in I 7. Many hold that his definitive argument is found in the first half of I 7 itself; I argue that this view is mistaken: the considerations raised there do not form the basis of any self-standing argument for Aristotle's doctrine of principles, but rather play a subordinate role in a larger argument begun in earnest in I (...) 5. This larger argument stalls in I 6, which ends in aporta; I argue that the problem lies in the fact that Aristotle's reasoning in I 6 thoroughly undermines his reasoning in I 5 (on which I 6 is ostensibly supposed to build). I further argue that the materials necessary for resolving this problem, and thereby allowing the argument begun in I 5 to reach its proper conclusion, are supplied by the thesis that organizes the first half of I 7. Along the way I offer some remarks about Aristotle's doctrine of principles, arguing that it is about the principles of natural substance (as opposed to coming to be or change). I also offer some remarks about the thesis which organizes the first half of I 7.1 argue negatively that it is not anything like a preliminary statement of Aristotle's doctrine of principles. I argue positively that it reflects Aristotle's idea that there are two distinct kinds of effect change has upon things (one constructive, the other destructive). One of these effects lies behind Aristotle's reasoning in I 5, the other comes to the fore in 16; the achievement of the first half of I 7 is to reconcile these seemingly competing conceptions by finding a place for them both in a unified account of coming to be and its subjects.

Among all their sensations, agents need to distinguish between those caused by themselves and those caused by external causes. The ability to infer agency is particularly challenging under conditions of uncertainty. Within the predictive processing framework, this should happen through active control of prediction error that closes the action-perception loop. Here we use a novel, temporally-sensitive, behavioural proxy for prediction error to show that it is minimised most quickly when volatility is high and when participants report agency, regardless of the (...) accuracy of the judgement. We demonstrate broad effects of uncertainty on accuracy of agency judgements, movement, policy selection, and hypothesis switching. Measuring autism traits, we find differences in policy selection, sensitivity to uncertainty and hypothesis switching despite no difference in overall accuracy. (shrink)

Anxiety disorders are one of the most prevalent mental disorders globally, and 63% of those diagnoses are of women. Although widely acknowledged across health disciplines and news and social media outlets, the majority of attention has left assumptions underlying women's anxiety in the twenty-first century unquestioned. Drawing on my own experiences of anxiety, I will the explore both concept and diagnosis in the Western world. Reflecting on my own experiences through a critical feminist lens, I will investigate the construction of (...) anxiety as mental disorder in the context of neoliberal late-stage capitalism, heteropatriarchy, and biomedical psychiatry. Tracing the postpositivistic foundations of anxiety, as well as the historical and ongoing medicalization and pathologization of women, I will critically consider the sociopolitical implications of constructing anxiety as biomedical disorder. Assumptions underlying mental health will be explored within the context of the construction, experience, and operationalization of gender and the way gender intersects with diverse positionalities, power, knowledge, and neoliberal governance. Weaving the voices of women poets with the biomedical language of disorder, this critical-realist inquiry will explore my anxiety as it relates to the epidemic levels of anxiety among other women, and the late-stage capitalist world within which anxiety flourishes.

Musical life became disrupted in 2020 due to the COVID-19 pandemic. Many musicians and venues turned to online alternatives, such as livestreaming. In this study, three livestreamed concerts were organized to examine separate, yet interconnected concepts—agency, presence, and social context—to ascertain which components of livestreamed concerts facilitate social connectedness. Hierarchical Bayesian modeling was conducted on 83 complete responses to examine the effects of the manipulations on feelings of social connectedness with the artist and the audience. Results showed that in concert (...) 1, where half of the participants were allowed to vote for the final song to be played, this option did not result in the experience of more agency. Instead, if their preferred song was played (regardless of voting ability) participants experienced greater connectedness to the artist. In concert 2, participants who attended the concert with virtual reality headsets experienced greater feelings of physical presence, as well as greater feelings of connectedness with the artist, than those that viewed a normal YouTube livestream. In concert 3, attendance through Zoom led to greater experience of social presence, but predicted less connectedness with the artist, compared to a normal YouTube livestream. Crucially, a greater negative impact of COVID-19 (e.g., loneliness) predicted feelings of connectedness with the artist, possibly because participants fulfilled their social needs with this parasocial interaction. Examining data from all concerts suggested that physical presence was a predictor of connectedness with both the artist and the audience, while social presence only predicted connectedness with the audience. Correlational analyses revealed that reductions in loneliness and isolation were associated with feelings of shared agency, physical and social presence, and connectedness to the audience. Overall, the findings suggest that in order to reduce feelings of loneliness and increase connectedness, concert organizers and musicians could tune elements of their livestreams to facilitate feelings of physical and social presence.

Over the past twenty-five years, thirty-seven states and the US Congress have passed mental health and substance use disorder (MH/SUD) parity laws to secure nondiscriminatory insurance coverage for MH/SUD services in the private health insurance market and through certain public insurance programs. However, in the intervening years, litigation has been brought by numerous parties alleging violations of insurance parity. We examine the critical issues underlying these legal challenges as a framework for understanding the areas in which parity enforcement is lacking, (...) as well as ongoing areas of ambiguity in the interpretation of these laws. We identified all private litigation involving federal and state parity laws and extracted themes from a final sample of thirty-seven lawsuits. The primary substantive topics at issue include the scope of services guaranteed by parity laws, coverage of certain habilitative therapies such as applied behavioral analysis for autism spectrum disorders, credentialing standards for MH/SUD providers, determinations regarding the medical necessity of MH/SUD services, and the application of nonquantitative treatment limitations under the 2008 federal parity law. Ongoing efforts to achieve nondiscriminatory insurance coverage for MH/SUDs should attend to the major issues subject to private legal action as important areas for facilitating and monitoring insurer compliance.

A wide range of countries decided to go into lockdown to contain the coronavirus disease (COVID-19) pandemic of 2020, a setting separating people and restricting their movements. We investigated how musicians dealt with this sudden restriction in mobility. Responses of 234 people were collected. The majority of respondents (95%) resided in Belgium or the Netherlands. Results indicated a decrease of 79% of live music making in social settings during lockdown compared with before lockdown. In contrast, an increase of 264% was (...) demonstrated for online joint music making. However, results showed that most respondents were largely or even completely unaccustomed with specialized platforms for online joint music making (e.g., JamKazam, Jamulus). Respondents reported to mostly use well-known video-conferencing platforms such as Zoom and Skype when playing together virtually. However, when such video-conferencing platforms were used, they were often not employed for synchronized playing and were generally reported to insufficiently deal with latency issues. Furthermore, respondents depending on music making as their main source of income explored online real-time methods significantly more than those relying on other income sources. Results also demonstrated an increase of 93% in the use of alternative remote joint music-making methods (e.g., recording parts separately and subsequently circulating these digital recordings). All in all, results of this study provide a more in-depth view on joint music making during the first weeks of lockdown induced by the COVID-19 pandemic of 2020, and demonstrate users’ perceptions of performance and usability of online real-time platforms as well as alternative methods for musical interaction.

The authors of the feature article argue against implied consent in all episiotomy cases, but allow that opt-out consent might be appropriate in limited circumstances.1 However, they do not indicate how clinicians should assess whether the pregnant person is capable of consenting in this way during an obstetric emergency. This commentary will focus on how capacity should be determined during these circumstances, suggest next steps for clinicians if capacity is deemed uncertain or absent, and discuss the appropriate role for opt-out (...) consent in labour. Previous studies investigating the extent to which pregnant persons retain decision-making capacity during labour have shown poor recall, a component of capacity, about consent processes during obstetric emergency procedures in 14%–49% of cases.1 2 As the feature article acknowledges, this does not mean that pregnant persons should be assumed to lack decision-making capacity during labour. Although pain, labour intensity, exhaustion and medications can make consenting processes during labour more difficult and it is possible that these factors will result in the impaired ability of the pregnant person to make informed and voluntary decisions about treatment options, this possibility of impaired capacity should not be taken as the expected outcome nor should it be used as an excuse to skip consenting procedures.1 2 The default to treat labouring patients as able to make their own decisions still stands, although signs that a person lacks ….

Abstract:There is a storied history of Native and Indigenous feminisms on Turtle Island (North America). We are fortunate that many of those stories birthed from an ancestral tradition of storytelling and survivance were captured in the canonical feminist anthology This Bridge Called My Back: Writings of Radical Women of Color. In celebration and commemoration of 40 years since This Bridge was first published we visit with three of the books original Native and Indigenous contributors–Chrystos, Max Wolf Valerio, and Jo Carrillo–to (...) recount old as well as new stories as they explore what Native and Indigenous feminisms mean to them and their continued work for Indigenous visibility. The conversation provides a unique intergenerational vision for conceptualizing contemporary Native and Indigenous feminisms all the while building upon the legacy and path set forth by amazing Native and Indigenous women trailblazers.

Many autistic behaviours can rightly be classified as adaptive, but why these behaviours differ from adaptive neurotypical behaviours in the same environment requires explanation. I argue that predictive processing accounts best explain why autistic people engage different adaptive responses to the environment and, further, account for evidence left unexplained by the social motivation theory.

In this paper we provide an interpretation of Aristotle's rule for the universal quantifier in Topics Θ 157a34–37 and 160b1–6 in terms of Paul Lorenzen's dialogical logic. This is meant as a contribution to the rehabilitation of the role of dialectic within the Organon. After a review of earlier views of Aristotle on quantification, we argue that this rule is related to the dictum de omni in Prior Analytics A 24b28–29. This would be an indication of the dictum’s origin in (...) the context of dialectical games. One consequence of our approach is a novel explanation of the doctrine of the existential import of the quantifiers in dialectical terms. After a brief survey of Lorenzen's dialogical logic, we offer a set of rules for dialectical games based on previous work by Castelnérac and Marion, to which we add here the rule for the universal quantifier, as interpreted in terms of its counterpart in dialogical logic. We then give textual evidence of the use of that rule in Plato's dialogues, thus showing that Aris... (shrink)

This paper addresses a dichotomy in the attitudes of some clinicians and bioethicists regarding whether there is a moral difference between deactivating a cardiac pacemaker in a highly dependent patient at the end of life, as opposed to standard cases of withdrawal of treatment. Although many clinicians hold that there is a difference, some bioethicists maintain that the two sorts of cases are morally equivalent. The author explores one potential morally significant point of difference between pacemakers and certain other life-sustaining (...) treatments: specifically, that the former are biofixtures, which become part of the patient in a way that the latter do not. The concept of the pacemaker as biofixture grants pacemakers a unique moral status that gives reason to treat a pacemaker the same as other parts of the patient that are necessary to sustain life. The author employs this biofixture analysis to affirm the intuition that deactivating a pacemaker in a highly dependent patient at the end of life is, in moral terms, more analogous to active euthanasia than it is to standard cases of withdrawal of treatment. The paper concludes with consideration of potential implications for further implantable medical technologies, such as ventricular assist devices and total artificial hearts. (shrink)

Life-saving health resources like organs for transplant and experimental medications are persistently scarce. How ought we, morally speaking, to ration these resources? Many hold that, in any morally acceptable allocation scheme, the young should to some extent be prioritized over the old. Govind Persad, Alan Wertheimer and Ezekiel Emanuel propose a multi-principle allocation scheme called the Complete Lives System, according to which persons roughly between 15 and 40 years old get priority over younger children and older adults, other things being (...) equal. They defend this ‘modified youngest first’ principle in part by appealing to the greater social investment that has been made in 15-year-olds than in younger children. Ruth Tallman has proposed a distinctive defense of modified youngest first, one that appeals not at all to social investment. We find this defense wanting. Tallman’s argument depends on the idea, which we try to show to be implausible, that allocations should maximize the number of people in the midst of a possibly complete life who actually complete their lives. Moreover, Tallman does not justify the priority modified youngest first gives 15-year-olds over, for example, 5-year-olds. Tallman fails to dispel a serious shortcoming with modified youngest first: its fundamental unfairness to pre-adolescents. (shrink)

Dialogical logic is a game-theoretical approach to logic. Logic is studied with the help of certain games, which can be thought of as idealized argumentations. Two players, the Proponent, who puts forward the initial thesis and tries to defend it, and the Opponent, who tries to attack the Proponent’s thesis, alternately utter argumentative moves according to certain rules. For a long time the dialogical approach had been worked out only for classical and intuitionistic logic. The seven papers of this dissertation (...) show that this narrowness was uncalled for. The initial paper presents an overview and serves as an introduction to the other papers. Those papers are related by one central theme. As each of them presents dialogical formulations of a different non-classical logic, they show that dialogical logic constitutes a powerful and flexible general framework for the development and study of various logical formalisms and combinations thereof. As such it is especially attractive to logical pluralists that reject the idea of “the single correct logic”. The collection contains treatments of free logic, modal logic, relevance logic, connexive logic, linear logic, and multi-valued logic. (shrink)

My intention in writing this article is to illustrate how I engage with the process of orienting to the meaning of pedagogy by inquiring into several moments in my life where I am able to fully experience its um. I begin this phenomenological inquiry by plunging into my experience on a teeter-totter as a young child, and use the sense of ups and downs as a metaphor for the tensions of weight and weightlessness, comfort and challenge that characterize the pedagogical (...) world. I then attempt to gain a more perceptual understanding of pedagogy by narrowing in on the suspended moment, which becomes a metaphor for the pedagogical moments of support, vulnerability, and opening that emanate from this tension. In these particular moments, I am able to dwell in the spaces in-between my everyday ups and downs and become existentially conscious and pedagogically connected to the world around me. By metaphorically connecting each of these moments to my teeter-totter experience, I illustrate how embracing the tensions of life and allowing myself to dwell in a suspended moment, deepens my perceptual understanding of pedagogy and influences my current pedagogical practice as a new teacher and master’s student.

Goal-directed spatial decision making video games combine spatial mapping, memory, and reward; all of which can involve hippocampal excitation through suppression of an inhibitory neurotransmitter, γ-aminobutyric acid. In this study, GABA was measured before and after 30 min of video game play within a voxel around the hippocampus. It was predicted that all participants would experience a decrease in GABA during gaming as a result of in-game rewards; and, those who were most competitive with the goal-directed spatial decision making game (...) would display lower hippocampal GABA concentrations after gaming. Those who were not competitive, because they were too skilled or not skilled enough, would demonstrate higher hippocampal GABA concentrations after gaming. While there were no significant differences in hippocampal GABA before and after gaming for gamers and non-gamers alike, there was a significant quadratic regression between performance on a spatial working memory task and post-gaming hippocampal GABA concentrations.
