Reduced Environmental Stimulation Therapy (REST) alters the balance of sensory input to the nervous system by systematically attenuating sensory signals from visual, auditory, thermal, tactile, vestibular, and proprioceptive channels. Previous research from our group has shown that REST via floatation acutely reduces anxiety and blood pressure while simultaneously heightening interoceptive awareness in clinically anxious populations. Anorexia nervosa (AN) is an eating disorder characterized by elevated anxiety, distorted body representation, and abnormal interoception, raising the question of whether REST might positively impact (...) these symptoms. However, this approach has never been studied in eating disorders and it is unknown whether exposure to REST might worsen AN symptoms. To examine these possibilities we conducted an open-label study to investigate the safety and tolerability of REST in AN. We also explored the impact of REST on affective symptoms, body image disturbance, and interoception. Twenty-one partially weight-restored AN outpatients completed a protocol involving four sequential sessions of REST: reclining in a zero-gravity chair, floating in an open pool, and two sessions of floating in an enclosed pool. All sessions were 90 minutes, approximately one week apart. We measured orthostatic blood pressure before and immediately after each session (primary outcome), in addition to collecting blood pressure readings every 10 minutes during the session using a wireless waterproof system as a secondary outcome measure. Each participant's affective state, awareness of interoceptive sensations, and body image was assessed before and after every session (exploratory outcomes). There was no evidence of orthostatic hypotension following floating, and no adverse events (primary outcome). Secondary analyses revealed that REST induced statistically significant reductions in blood pressure, anxiety and negative affect, heightened awareness of cardiorespiratory but not gastrointestinal sensations, and reduced body image dissatisfaction. The findings from this initial trial suggest that individuals with AN can safely tolerate the physical effects of REST via floatation. Future randomized controlled trials will need to investigate whether these initial observations of improved anxiety, interoception, and body image disturbance can be effectively extended to acutely ill AN populations.

Traditional engineering courses typically approach teaching and problem solving by focusing on the physical dimensions of those problems without consideration of dynamic social and ethical dimensions. As such, projects can fail to consider human rights, community questions and concerns, broader impacts upon society, or otherwise result in inequitable outcomes. And, despite the fact that students in engineering receive training on the Professional Code of Ethics for Engineers, to which they are expected to adhere in practice, many students are unable to (...) recognize and analyze real-life ethical challenges as they arise. Indeed, research has found that students are typically less engaged with ethics—defined as the sensitivity and judgment of microethics and macroethics, sensitivity to diversity, and interest in promoting organizational ethical culture—at the end of their engineering studies than they were at the beginning. As such, many studies have focused on developing and improving the curriculum surrounding ethics through, for instance, exposing students to ethics case studies. However, such ethics courses often present a narrow and simplified view of ethics that students may struggle to integrate with their broader experience as engineers. Thus, there is a critical need to unpack the complexity of ethical behavior amongst engineering students in order to determine how to better foster ethical judgment and behavior. Promoting ethical behavior among engineering students and developing a culture of ethical behavior within institutions have become goals of many engineering programs. Towards this goal, we would like to present an overview of the current scholarship of engineering ethics and propose a theoretical framework of ethical behavior using a review of articles related to engineering ethics from 1997-2020. The review engages in theories across disciplines including philosophy, education, and psychology. In this work-in-progress paper, we present a subset of initial results based on a review of the first 50 articles out of the systematically selected 409 articles from Springer, Engineering Village, and EBSCO-Education Full Text. Preliminary results identify two major kinds of drivers of ethical behavior, namely individual level ethical behavior drivers and institutional drivers. Our preliminary results indicate that a sensitivity to both microethics and macroethics as well as the implicit and explicit understanding of ethics are essential in promoting ethical behavior amongst students. Furthermore, while drivers of ethical behavior at the individual level is important, one should not ignore the roles of the drivers of ethical behavior at the institutional level in promoting a collective ethical culture within organizations. The review also points to a need to focus on increasing students’ macroethical sensitivity to topics such as sustainability and protection of human rights. This research thus addresses the need, driven by existing scholarship, 2 to identify a conceptual framework for explaining how ethical judgment and behavior in engineering can be further promoted.

While the technical aspects of engineering are emphasized in education and industry, the ethical aspects are, in some ways, just as vital. Engineering instructors should teach undergraduates about their ethical responsibilities in the realm of engineering. Students would then be more likely to grasp their responsibilities as professionals. For many students, undergraduate study is a time of growth and change, with their ethical development just beginning to take shape. In this study, we aim to understand the progression of ethical development (...) for engineering undergraduate students and identify key factors that may contribute to their development. To help us assess ethical development, we deployed in Fall 2020 a survey to undergraduate engineering students at two universities; the survey entailed the Defining Issues Test-2 (DIT-2). The DIT-2 evaluates ethical development based on Kohlberg’s theory of moral development; the test recognizes three levels of morality—preconventional, conventional, and postconventional. This study evaluates the associations between students’ university and class year and their Personal Interest, Maintaining Norms, and N2 scores. We utilized the results of a multivariate analysis of variance (MANOVA) to address the following research question: _Is a student’s ethical development associated with their university and class year?_ The results of the analysis reveal that students’ ethical development appear to differ between universities and to lie along a continuum, changing from first-year students to seniors of engineering undergraduate study.

Engineering ethics can be divided into three spheres, namely the technical, the professional, and the social. Ideally, engineering students should engage with all three spheres of ethics, but the literature suggests that this might not be the case. How do engineering students engage with the three spheres of engineering ethics during a global pandemic? The COVID-19 pandemic represents a dramatic and ongoing real-world challenge affecting many students personally. This research explores the extent to which engineering students engage with each sphere (...) of engineering ethics by examining how engineering students understand their roles in addressing the pandemic and its implications. We conducted a survey with undergraduate engineering students (n = 410) at a university in the Midwest. Qualitative analysis suggests that there was low engagement with both social ethics and professional ethics among respondents, while there was higher engagement with technical ethics. Quantitative analysis suggests that non-conservative engineering students from less wealthy families in our study show higher engagement with technical ethics as compared to conservative engineering students from less wealthy families. Non-conservative engineering students from wealthy families, however, show similar engagement with technical ethics as compared to conservative engineering students from wealthy families. In addition, engineering students from both wealthy and less wealthy families show higher engagement with technical ethics if they reside in urban areas as compared to engineering students from both wealthy and less wealthy families in non-urban areas. In addition, the difference in terms of engagement with technical ethics between non-urban engineering students from less wealthy families and urban engineering students from less wealthy families is larger than the difference in terms of engagement with technical ethics between non-urban engineering students from wealthy families and urban engineering students from wealthy families. Further investigation will be needed to explain these findings. However, qualitative results confirm that, despite the potential for the pandemic to encourage engagement with all three spheres of ethics, there continues to be low engagement with ethics beyond the technical level.

_Matters of Mind_ examines the mind-body problem. It offers a chapter by chapter analysis of debates surrounding the problem, including visual experience, consciousness and the problem of Zombies and Ghosts. It will prove invaluable for those interested in epistemology, philosophy of mind and cognitive science.

One of the most innovative and brilliant philosophers of his generation, but largely neglected until he was brought to public attention by Gilles Deleuze, Gilbert Simondon presents a challenge to nearly every category and method of traditional philosophy. Psychic and Collective Individuation is undoubtedly Simondon's most important work and its influence, clearly felt in Stiegler and DeLanda, has continued to grow. David Scott provides the first full introduction to this work, which will inspire as well as instruct philosophers working (...) in Continental thought, philosophy of science, social theory and political philosophy.

I argue that our knowledge of the world's causal structure does not generate a sound argument for physicalism. This undermines the popular view that physicalism is the only scientifically respectable worldview.

In the middle of the twentieth century a dispute erupted between the chief architect of Logical Empiricism, Rudolf Carnap, and Logical Empiricism’s chief reformer, Willard van Orman Quine -- who was attempting to save what he took to be its main insights by recasting them in a more acceptable form. Though both eschewed metaphysics of the traditional apriori sort, and both were intent on making the investigation of science the center of philosophy, they disagreed about how to do so. Part (...) of the disagreement involved the nature of ontological disputes. The central documents in the debate are: (i) Quine’s 1948 article, “On What There Is,” which tells us how to discern ontological.. (shrink)

Many of the activities of clinical practice happen to, with or upon vulnerable human beings. For this reason numerous nursing authors draw attention to or claim a significant moral domain in clinical practice. A number of nursing authors also discuss the emotional involvement and/or emotional labour which is often experienced in clinical practice. In this article I explore the importance of emotion for moral perception and moral agency. I suggest that an aspect of being a good nurse is having an (...) emotional sensitivity to other human beings (patients), because this emotional sensitivity allows the nurse to perceive more accurately the context and perspective of the patient. It is thus important to the moral agency of the nurse and to morally sensitive clinical practice. As such education of the emotions should be a feature of the moral education of the nurse. A useful conception of the role of educated emotion in the moral life can be discovered in Aristotelian ethics. (shrink)

In 1947 Donald Cary Williams claimed in The Ground of Induction to have solved the Humean problem of induction, by means of an adaptation of reasoning first advanced by Bernoulli in 1713. Later on David Stove defended and improved upon Williams’ argument in The Rational- ity of Induction (1986). We call this proposed solution of induction the ‘Williams-Stove sampling thesis’. There has been no lack of objections raised to the sampling thesis, and it has not been widely accepted. In our (...) opinion, though, none of these objections has the slightest force, and, moreover, the sampling thesis is undoubtedly true. What we will argue in this paper is that one particular objection that has been raised on numerous occasions is misguided. This concerns the randomness of the sample on which the inductive extrapolation is based. (shrink)

In the Prolegomena to De Jure Belli ac Pacis, Hugo Grotius expounds his theory of natural law by way of reply to a skeptical challenge from the Greek Academic Carneades. Though this dialectical context is undeniably important for understanding Grotian natural law, commentators disagree about the substance of Carneades’s challenge. This paper aims to give a definitive reading of Carneades’s skeptical argument, and, by reconstructing Grotius’s reply, to settle some longstanding debates about Grotius’s conception of natural law. I argue that (...) Grotius held a Stoic view of natural law, endorsing both the doctrine of eudaimonism and the claim that moral obligations are natural, not grounded in divine command. Consequently, Grotius’s view of natural law has more continuity with pre-modern, indeed ancient, morality than is usually supposed. However, I argue that we can still understand Grotius as a founder of modern moral philosophy. (shrink)

Though the “internal point of view” is perhaps H.L.A. Hart’s greatestcontribution to legal theory, this concept is also often and easily misunderstood. This is unfortunate, not only because these misreadings distort Hart’s theory, but, more importantly, because they prevent us from appreciating the infirmities of sanction-centered theories of law and the compelling reasons why they ought to be rejected. In this paper, I try to address some of these confusions. What, exactly, is the internal point of view? What role (or (...) roles) does it play in Hart’s theory? And how does an adequate appreciation for the centrality of the internal point of view lead to the rejection of sanction-centered theories? (shrink)

Though the question is ontological, I will approach it through another, partially linguistic, question. What must natural kinds be like, if the conventional wisdom about natural kind terms is correct? Although answering this question won’t tell us everything we want to know, it will, I think, be useful in narrowing the range of feasible ontological alternatives. I will therefore summarize what I take to be the contemporary linguistic wisdom, and then test different proposals about kinds against it. As we will (...) see, some fare better than others.

Social epidemiology has made a powerful case that health determined not just by individual-level factors such as our genetic make-up, access to medical services, or lifestyle choices, but also by social conditions, including the economy, law, and culture. Indeed, at the level of populations, evidence suggests that these “structural” factors are the predominant influences on health. Legal scholars in public health, including those in the health and human rights movement, have contended that human rights, laws, and legal practices are powerfully (...) linked to health. Social epidemiology and health-oriented legal scholarship are complementary in their focus and their research needs. Legal scholarship has identified plausible ways in which legal and human rights factors could be influencing health, but empirical evidence has been limited. (shrink)

Chase Wrenn argues that there are no epistemic duties. When it appears that we have an epistemic duty to believe, disbelieve or suspend judgement about some proposition P, we are really under a moral obligation to adopt the attitude towards P that our evidence favours. The argument appeals to theoretical parsimony: our conceptual scheme will be simpler without epistemic duties and we should therefore drop them. I argue that Wrenn’s strategy is flawed. There may well be things that we ought (...) to do on epistemic grounds alone. (shrink)

In standard models of decision making, participation in violent political action is understood as the product of instrumentally rational reasoning. According to this line of thinking, instrumentally rational individuals will participate in violent political action only if there are selective incentives that are limited to participants. We argue in favor of an alternate model of political violence where participants are motivated by moral commitments to collective sacred values. Correlative and experimental empirical evidence in the context of the Israeli–Palestinian conflict strongly (...) supports this alternate view. (shrink)

I reinterpret Bohr's attitude towards quantum mechanical formalism and its empirical content, based on his understanding of the correspondence principle and its approximate applicability. I suggest that Bohr understood complementarity as a limitation imposed by the commutation relations upon the applicability of the idealizations which had grounded the use of the correspondence principle. By discussing this interpretation against the contemporary background of discussions regarding “naïve realism” about operators (as observables), I suggest that a Bohrian view on the empirical content of (...) quantum mechanical operators may provide a middle ground between complete contextualism and an untenable realism about quantum properties.

This paper situates the moral domain of practice within the context of a particular description of nursing practice – one that sees human interaction at the heart of that practice. Such a description fits not only with professional rhetoric but also with literature from patients and recent empirical work exploring the nature of nursing practice.Martha Levine in her 1977 description of ethics, within the context of nursing practice, indicated that what was important from an ethical perspective was how we interact (...) with each other, with patients and colleagues, on a daily basis. What enables such interaction to display moral sensitivity, insight into patient need, and a focus on the good for the patient? Of relevance when answering this question is the empirical evidence indicating that professional socialization, as a nurse or a doctor, may dull the individual’s moral sense. If this is the case, cognizance needs to be taken of such evidence when identifying theoretical approaches from mainstream ethics that may provide insight and value for nurse education. It is suggested that such insight and value can be gained from a consideration of the work of Aristotle, Murdoch, and Vetlesen. (shrink)

The article examines the surprising role of Rousseau in the revival of liberal and humanist thought in contemporary French political thought. The choice of Rousseau as an inspiration and source of humanism is an illuminating indication of a shift in French thought. The authors concentrate on the natural- rights republicanism of Luc Ferry and Alain Renaut and the critical humanism of Tzvetan Todorov. While these thinkers all appeal to Rousseau's definition of humanity in terms of freedom, they draw on different (...) aspects of his thought and his relationship to the philosophic tradition. Their different receptions of Rousseau reveal tensions in the humanist revival and provoke reflection on the relationships among republicanism, liberalism and humanism in contemporary France.

In his early lecture courses, Martin Heidegger exhibited an abiding interest in human life. He believed that human life has philosophical import while it is actually being lived; language has philosophical import while it is being spoken. In this book, Scott Campbell traces the development of Heidegger's ideas about factical life through his interest in Greek thought and its concern with Being. He contends that Heidegger's existential concerns about human life and his ontological concerns about the meaning of Being (...) crystallize in the notion of Dasein as the Being of factical human life. Emphasizing the positive aspects of everydayness, Campbell explores the contexts of meaning embedded within life; the intensity of average, everyday life; the temporal immediacy of life in early Christianity; the hermeneutic pursuit of life's self-alienation; factical spatiality; the temporalizing of history within life; the richness of the world; and the facticity of speaking in Plato and Aristotle. He shows how Heidegger presents a way of grasping human life as riddled with deception but also charged with meaning and open to revelation and insight. (shrink)

Duties of beneficence are not well understood. Peter Singer has argued that the scope of beneficence should not be restricted to those who are, in some sense, near us. According to Singer, refusing to contribute to humanitarian relief efforts is just as wrong as refusing to rescue a child drowning before you. Most people do not seem convinced by Singer’s arguments, yet no one has offered a plausible justification for restricting the scope of beneficence that doesn’t produce counterintuitive results elsewhere. (...) I offer a defence of this restricted scope by introducing the notion of unique dependence, a notion that is both intuitively attractive and theoretically grounded. It explains why your reason to rescue the drowning child is more stringent than your reason to contribute to humanitarian relief, while blocking the conclusion that we have no reason at all to aid distant sufferers .

The surface appeal of the Social Responsibility theory of the press emerging in the report of the Commission on Freedom of the Press in 1947 has made Social Responsibility theory broadly acceptable. Yet, I declare it inconsistent with the American social system. Three concepts are discussed - societal obligation, individual rights, and interpersonal relationships - as necessary for a new moral theory that serves valid societal goals.

Although Caenorhabditis elegans was chosen and modified to be an organism that would facilitate a reductionist program for neurogenetics, recent research has provided evidence for properties that are emergent from the neurons. While neurogenetic advances have been made using C. elegans which may be useful in explaining human neurobiology, there are severe limitations on C. elegans to explain any significant human behavior.

In recent years, it has become common to defend science against charges of bias against the supernatural by explaining that science must remain methodologically natural but does not assume metaphysical naturalism. While such a response is correct, some details about the distinction between methodological naturalism and ontological or metaphysical naturalism have been lacking, as has a clear understanding of the distinction between the methodological restriction of science to natural explanations and naturalistic claims about the scope of those methods. We still (...) require an account of the natural that explains well why science is restricted to giving naturalistic methods, and why the pursuit of natural explanations is not tantamount to the assumption that only natural causes exist. I suggest that the distinguishing characteristics of the natural are not metaphysical at all but broadly epistemological, concerning goals of intersubjectivity and predictability. I argue that by focusing on naturalistic goals we can better explain why the pursuit of natural explanations need not presume any purely natural metaphysics. But I also suggest that the adoption of natural methods is not entirely metaphysically neutral, as it is associated with values that may be more closely associated with some metaphysical views than others.

In lieu of an abstract, here is a brief excerpt of the content:Simulation, Subjective Knowledge, and the Cognitive Value of Literary NarrativeScott R. Stroud (bio)IntroductionLiterary narrative holds the power to move individuals to thought, reflection, action, and belief. According to a longstanding view of literature, it is this impact on the reader that leads to literary narrative being valued so highly in our culture and in others. What exactly is the value of literature? Humanists such as Peter Lamarque and Stein (...) Olsen1 argue for this value in terms of perennial themes that literature allows one to "grapple with," as opposed to cognitivist accounts that discuss the value of literary narrative in terms of conveyed truths or knowledge. One particularly important position that explains the cognitive value of literature can be labeled the "Subjective Knowledge Theory" (SKT). Such an account of literature places its value in the subjective perspectives or experiences the narrative opens up to the reader. Thus, one can gain knowledge of "what it is like" to be caught in the throes of jealousy, endangered by an opposing army, or captivated by the lure of magical prowess. Lamarque and Olsen, however, argue that SKT is fundamentally flawed in its analysis of knowledge derivable from the literary narrative and in terms of its account of literary practice.I wish to defend a version of SKT in this article. In order to do so, I make and defend the following claims. First, Lamarque and Olsen's critique of SKT relies on a conflation of two distinct types of knowledge—the knowledge provided by the simulated subjective experience and its appropriation/ generalization to forms useful for the reader's real life activities. I will argue that the former of these outcomes is due strictly to the aesthetic features of the literary narrative, whereas the second involves a non-necessary psychological reaction to the text (that is, judgments of the veracity or usefulness of the text for one's own purposes). By conflating both of these into the cognitive knowledge derivable from the text, Lamarque and Olsen's critique can [End Page 19] gain its purchase against SKT. If these two processes and the resultant sorts of knowledge are separated, then the SKT account does seem to show how literature holds value in itself and in relation to the reader's moral activities/ judgments. Second, the process of simulation is the primary means by which one can gain any type of subjective knowledge from a literary narrative. This type of knowledge will be gained by virtue of the literary narrative's aesthetic qualities, which result in a certain type of activity in the reader. Third, I will argue that the second sort of knowledge—that derived from the simulated subjective experience—results from the process of reader identification with the values, beliefs, and/or behaviors of the simulated agent. This sense of identification involves selective appropriation and generalization and will be shown not to be subject to the critiques of simple identification offered by Noël Carroll.2 It is at this stage that individuals learn what they believe they ought to value, how they ought to act, and what they should believe from their experience of simulation in reading the literary narrative. Notice that this knowledge is separate from the first sort of knowledge, which is knowledge of what it is like to experience x through y's eyes.As I elucidate and defend these claims, I hope it will become clear that this is an account that does justice to the value resident in literature and in the activities readers do after they partake in the aesthetic object of the literary narrative. Thus, I will conclude by showing how this account does not fall prey to the conflation that both critics and supporters of SKT commit in muddling the different types of knowledge available from and in relation to a literary narrative.Before I proceed, it is important that some basic concepts are clearly set forth. A narrative can be defined as any representation of two or more events over time. The number of events and the relationship among them can be as simple or complex as one likes, but the crucial aspect is that the representation supplies the... (shrink)

Three natural assumptions about rationality lead to conflict when they are formalized in natural ways. The paper examines how the assumptions are built into formal frameworks and why they lead to conflict.

While it is widely agreed that decoherence will not solve the measurement problem, decoherence has been used to explain the “emergence of classicality” and to eliminate the need for a Copenhagen edict that some systems simply have to be treated as classical via a quantum-classical “cut”. I argue that decoherence still relies on such a cut. Decoherence accounts derive classicality only in virtue of their incompleteness, by omission of part of the entangled system of which the classical-appearing subsystem is a (...) part. I argue that this omission is only justified by implicit classical assumptions that objectify a subsystem and are employed via either a traditional Copenhagen cut or a functionally equivalent imposition of separability on a system in a non-separable state. I argue that decoherence cannot derive classicality without assuming it in some other form, and I provide an analysis of when it is appropriate to make these otherwise implicit classical assumptions by adopting a minimalistic Copenhagen-style approach to measurement. Finally, I argue that, ironically, the conditions for making these assumptions may be better satisfied in standard measurement situations than in cases of environmental monitoring. (shrink)

Sound propagation within certain non-relativistic condensed matter models obeys a relativistic wave equation despite such systems admitting entirely non-relativistic descriptions. A natural question that arises upon consideration of this is, “do devices exist that will experience the relativity in these systems?” We describe a thought experiment in which ‘acoustic observers’ possess devices called sound clocks that can be connected to form chains. Careful investigation shows that appropriately constructed chains of stationary and moving sound clocks are perceived by observers on the (...) other chain as undergoing the relativistic phenomena of length contraction and time dilation by the Lorentz factor, \, with \ the speed of sound. Sound clocks within moving chains actually tick less frequently than stationary ones and must be separated by a shorter distance than when stationary to satisfy simultaneity conditions. Stationary sound clocks appear to be length contracted and time dilated to moving observers due to their misunderstanding of their own state of motion with respect to the laboratory. Observers restricted to using sound clocks describe a universe kinematically consistent with the theory of special relativity, despite the preferred frame of their universe in the laboratory. Such devices show promise in further probing analogue relativity models, for example in investigating phenomena that require careful consideration of the proper time elapsed for observers. (shrink)

“Public health practice” consists of activities and Programs managed by public health agencies to promote health and prevent disease, injury, and disability. Some of these activities might be deemed to fit within the broad definition of “research” under federal regulations, known as the Common Rule, designed to protect human research subjects. The Common Rule defines research as “a systeniatic investigation, including research development, testing and evaluation, designed to develop or contribute to generalizable knowledge.” Public health activities that might under some (...) circumstances be considered research include disease reporting, review of medical records, surveys, interviews, focus groups, specimen collection, and laboratory testing.There are questions about the extent to which the Common Rule applies or was intended to apply to public health practice: and it has been suggested in any case that Common Rule regulation of public health practice may not be socially optimal for both practical and principled reasons.
