A major requirement for humans is a breathable atmosphere. In microgravity, despite environmental life support systems regulating air exchange, astronauts complain about air quality, with elevated CO2-levels resulting in detrimental health and performance effects. We extend extant accounts of human respiration to include the role of gravity and buoyancy. Using computational fluid dynamics, we demonstrate that the absence of biothermal convection in microgravity reduces airflow around the human body. This impairs gas exchange by creating an environmental breathing deadspace (...) in front of the face, leading to significant CO2-rebreathing, with implications for astronaut health and countermeasures. In 1g, increasing ambient air temperature can also reduce efficient respiratory exchange, resulting in breathing conditions equivalent to those in microgravity, with implications for treating respiratory disease on Earth.

Critics of mass culture often identify 1950s-style status competition as one of the central forces driving consumerism. Thomas Frank has challenged this view, arguing that countercultural rebellion now provides the primary source of consumerism in our society, and that ‘cool’ has become its central ideological expression. This paper provides a rearticulation and defense of Frank's thesis, first identifying consumerism as a type of collective action problem, then showing how the ‘hip consumer’ is one who adopts a free-rider strategy in this (...) context.

The values that will govern choices among future energy systems are unlikely to be the same as the values we embrace today. This paper discusses principles of rational choice for agents expecting future value shifts. How do we ought to reason if we believe that some values are likely to change in the future? Are future values more, equally, or less important than present ones? To answer this question, I propose and discuss the Expected Center of Gravity Principle, which (...) articulates what I believe to be a reasonable compromise between present and future values.

All of us had fallen from 100 stories.Falling is rarely a good thing. It is something to avoid for safety, and such avoidance, for those of us fortunate enough to be in good health, has been burned into the unconscious memory of our muscles and bones. Unless we find ourselves in high places, or on some kind of precipice, falling tends not to be on the mind. It is, most of the time, a surprise.But it is also always a (...) possibility, in part because of one of those characteristics that define the human—our upright posture. Without this trait that.

Metaphors used to describe new technologies mediate public understanding of the innovations. Analyzing the linguistic, rhetorical, and affective aspects of these metaphors opens the range of issues available for bioethical scrutiny and increases public accountability. This article shows how such a multidisciplinary approach can be useful by looking at a set of texts about one issue, the use of a newly developed technique for genetic modification, CRISPRcas9.

Gravity and Grace was the first ever publication by the remarkable thinker and activist, Simone Weil. In it Gustave Thibon, the priest to whom she had entrusted her notebooks before her untimely death, compiled in one remarkable volume a compendium of her writings that have become a source of spiritual guidance and wisdom for countless individuals.

This grounded study investigated the negotiation of authorship by faculty members, graduate student mentors, and their undergraduate protégés in undergraduate research experiences at a private research university in the northeastern United States. Semi-structured interviews using complementary scripts were conducted separately with 42 participants over a 3 year period to probe their knowledge and understanding of responsible authorship and publication practices and learn how faculty and students entered into authorship decision-making intended to lead to the publication of peer-reviewed technical papers. Herein (...) the theoretical model for the negotiation of authorship developed through the analysis of these interviews is reported. The model identifies critical causal and intervening conditions responsible for the coping strategies faculty and students employ, which, in our study, appear to often produce unfortunate consequences for all involved. The undergraduate student researchers and their graduate student mentors interviewed in this study exhibited a limited understanding of authorship and the requirements for authorship in their research groups. The power differential between faculty and students, the students’ limited epistemic development, the busy-ness of the faculty, and the faculty’s failure to prioritize authorship have been identified as key factors inhibiting both undergraduate and graduate students from developing a deeper understanding of responsible authorship and publication practices. Implications for graduate education and undergraduate research are discussed, and strategies for helping all students to develop a deeper understanding of authorship are identified. (shrink)

As a continuation of the previous paper,Praying for a Miracle – Negative or Positive Impacts on Health Care, published in this research topic, this second paper aims at delving deeper into the same theme, but now from a simultaneously practical and conceptual approach. With that in mind, we revisit three theoretical models based on evidence, through which we can understand the role of a miracle in hospital settings and assess its impact in health contexts. For each of the (...) models described, we seek to illustrate the possible outcomes of belief in miracles as a modality of religious coping in situations of stress and suffering experienced by patients and caregivers in the face of gloomy diagnoses on coming across the limits of medicine to revert certain illnesses (e.g., child cancer) or biological conditions (e.g., fetal malformation). We posit that the judgment about how such a mechanism is healthy or not for each of the people involved (patient, caregiver, and/or health professional) depends on the modulation between the conception of the miracle adopted by the patient and/or caregiver and the concrete outcomes of the way of responding to the situations that accompany the gravity of the illness or condition. To better understand this process of psychological modulation that accompanies belief in miracles, we revisit the concepts of spirituality, religiosity, and religion, pointing out the connections and distinctions between them from a phenomenological perspective. We then present a conceptual model that takes these connections and distinctions into consideration to foster an understanding of miracles, their relations with the diversity of experiences of people who meet in hospital settings (patients, caregivers, and health professionals), and their respective impacts on healthcare.

In response to the many changes currently going on in health care, this book offers the combined insight and wisdom of a stellar group of scholars and professionals with extensive experience in the health care field. The book opens with a look at people's actual experience of health care today, from four different perspectives. It then addresses foundational questions, including the nature of medicine, nursing, and justice. Surveyed next are the changing economics of health care as (...) well as the impact of these changes on such areas as mental health care, long-term care, health care for minorities, and legal malpractice. The closing section of the book assesses from a Christian perspective available constructive alternatives, including creative funding strategies with special attention to the needs of poor persons, physician unions, and the use of "alternative medicine" therapies.

How patients and nurses experience the acute care psychiatric environment The concept of the therapeutic milieu was developed when patients’ hospitalizations were long, medications were few, and one‐to‐one nurse–patient interactions were the norm. However, it is not clear how the notion of ‘therapeutic milieu’ is experienced in American acute psychiatric environments today. This phenomenological study explored the experience of patients and nurses in an acute care psychiatric unit in the USA, by asking them, ‘What stands out to you about this (...) psychiatric hospital environment?’ Three figural themes emerged, contextualized by time, which was a source of stress to both groups: for patients there was boredom, and for nurses, pressure and chaos. Although they shared some themes, nurses and patients experienced them differently. For instance, nurses felt caged‐in by the Plexiglas‐enclosed nursing station, and patients felt caged‐in by the locked doors of the unit. The findings from this US study do not support the existence of the therapeutic milieu as described in the literature. Furthermore, although the nurse–patient relationship was yearned for by nurses, it was nearly absent from patients’ descriptions. The caring experienced by patients was mainly derived from interactions with other patients. (shrink)

Human beings are in the midst of very powerful shifts in our understanding of what it means to be a human. There is a non-trivial chance that sometime in the future humanity will transform itself, leading to an emergence of posthumans with God-like qualities – Homo Deificatio. Such a transformation has great potential for both good and bad. Posthumanism seeks to improve human nature, increase the human life- and health-span, extend its cognitive and physical capacities, and broaden its mastery (...) over the environment. As such, the notion of posthumanism implies a radical breaking off from, and reconceptualisation of, the state of being human. As neuroscientists, we aim to bring a neuroscientific perspective to this debate. Current scientific and technologic developments (related to brain and its augmentation) clearly demonstrate that what was formerly considered to be science fiction is slowly but firmly becoming a scientific reality.

_Gravity and Grace_ shows Weil's religious thoughts and ideas, drawn from many sources - Christian, Jewish, Indian, Greek and Hindu - and focusing on suffering and redemption. It brings the reader face to face with the profoundest levels of existence as Weil explores the relationship of the human condition to the realm of the transcendent.

Contemporary psychiatry faces serious challenges because it has failed to incorporate accumulated knowledge from basic neuroscience, neurophilosophy, and brain–mind relation studies. As a consequence, it has limited explanatory power, and effective treatment options are hard to come by. A new conceptual framework for understanding mental health based on underlying neurobiological spatial-temporal mechanisms of mental disorders (already gained by the experimental studies) is beginning to emerge.

ABSTRACT In this article, we first document the virtually complete absence of infectious disease examples and concerns at the time bioethics emerged as a field. We then argue that this oversight was not benign by considering two central issues in the field, informed consent and distributive justice, and showing how they might have been framed differently had infectiousness been at the forefront of concern. The solution to this omission might be to apply standard approaches in liberal bioethics, such as autonomy (...) and the harm principle, to infectious examples. We argue that this is insufficient, however. Taking infectious disease into account requires understanding the patient as victim and as vector. Infectiousness reminds us that as autonomous agents we are both embodied and vulnerable in our relationships with others. We conclude by applying this reunderstanding of agency to the examples of informed consent and distributive justice in health care. (shrink)

The article summarizes the theoretical and methodological knowledge about ecotourism as one of the viable types of tourism in the postmodern era, clarifies the patterns of its formation and development, a variety of approaches to its interpretation, interaction with other types of tourism, features of motivation and management in ecotourism. On the basis of the generalized data a number of perspective educational conditions is modeled: the orientation of the maintenance of pedagogical education on formation of steady positive motivation; updating the (...) content of professional training; availability of educational and methodical support; interrelation of competence, system and personal-activity approaches. Diagnostic methods relevant for postmodern education are selected: methods of diagnosing students' learning motivation; methods of diagnosis of value orientations in career; tests to determine the levels of formation of the components of professional competence. It is proved that the professional training of teachers who are able to use ecological tourism in their professional activities at a high level is one of the important conditions for increasing the interest of children and young people in physical education, tourism and sports, ensuring the necessary physical activity, developing, maintaining and strengthening their health, adaptation to the flexible postmodern society.

ABSTRACT Accurate self‐administration of antiretroviral medication therapy for HIV/aids is a significant clinical and ethical concern because of its implications for individual morbidity and mortality, the health of the public, and escalating healthcare costs. However, the traditional construction of patient medication adherence is oversimplified, myopic, and ethically problematic. Adherence relies on existing social power structures and western normative assumptions about the proper roles of patients and providers, and principally focuses on patient variables, obscuring the powerful socioeconomic and institutional influences (...) on behaviour. Some professionals advocate for alternate approaches to adherence, but many of the available alternatives remain conceptually underdeveloped. Using HIV/aids as an exemplar, this paper presents medication practice as a theoretical reconstruction and explicates its conceptual and ethical evolution. We first propose that one of these alternatives, medication practice, broadens the understanding of individuals’ medication‐taking behaviour, speaks to the inherent power inequities in the patient‐provider interaction, and addresses the ethical shortcomings in the traditional construal. We then integrate medication practice with feminist thought, further validating individuals’ situated knowledge, choices, and multiple roles; more fully recognizing the individual as a multidimensional, autonomous human being; and reducing notions of obedience and deference to authority. Blame is thus extricated from the healthcare relationship, reshaping the traditionally adversarial components of the interaction, and eliminating the view of adherence as a patient problem in need of patient‐centred interventions.

Two decades of research on euthanasia in the Netherlands have resulted into clear insights in the frequency and characteristics of euthanasia and other medical end-of-life decisions in the Netherlands. These empirical studies have contributed to the quality of the public debate, and to the regulating and public control of euthanasia and physician-assisted suicide. No slippery slope seems to have occurred. Physicians seem to adhere to the criteria for due care in the large majority of cases. Further, it has been shown (...) that the majority of physicians think that the euthanasia Act has improved their legal certainty and contributes to the carefulness of life-terminating acts. In 2005, eighty percent of the euthanasia cases were reported to the review committees. Thus, the transparency envisaged by the Act still does not extend to all cases. Unreported cases almost all involve the use of opioids, and are not considered to be euthanasia by physicians. More education and debate is needed to disentangle in these situations which acts should be regarded as euthanasia and which should not. Medical end-of-life decision-making is a crucial part of end-of-life care. It should therefore be given continuous attention in health care policy and medical training. Systematic periodic research is crucial for enhancing our understanding of end-of-life care in modern medicine, in which the pursuit of a good quality of dying is nowadays widely recognized as an important goal, in addition to the traditional goals such as curing diseases and prolonging life.

A number of philosophers have argued in favour of extended simples on the grounds that they are needed by fundamental physics. The arguments typically appeal to theories of quantum gravity. To date, the argument in favour of extended simples has ignored the fact that the very existence of spacetime is put under pressure by quantum gravity. We thus consider the case for extended simples in the context of different views on the existence of spacetime. We show that the (...) case for extended simples based on physics is far more complex than has been previously thought. We present and then map this complexity, in order to present a much more textured picture of the argument for extended simples. (shrink)

This is a nontechnical overview of how various approaches to quantum gravity suggest modifications to the way we conceptualize space and time. A theory of quantum gravity is needed to reconcile quantum physics with general relativity, our best theory for gravity. The most popular approaches to quantum gravity are string theory and loop quantum gravity. So far, no approach has been empirically successful, and there is no commonly accepted theory. Thus, the conclusions presented here are (...) tentative. Many approaches suggest that space and time—or perhaps, it is better to talk about spacetime—might not be fundamental. Various views on how to think about time in quantum gravity are briefly presented. (shrink)

This paper is in three sections. The first establishes that Newton, in spite of a well-known passage in a letter to Richard Bentley of 1692, did believe in action at a distance. Many readers may see this merely as an act of supererogation, since it is so patently obvious that he did. However, there has been a long history among Newton scholars of allowing the letter to Bentley to over-ride all of Newton’s other pronouncements in favour of action at a (...) distance, with devastating effects on our understanding of related aspects of his physics and his theology. Furthermore, this misconceived scholarly endeavour shows no sign of abating. The second section then offers a historical reconstruction, based on Newton’s writings, of how, when and why he began to accept actions at a distance and make them one of the cornerstones of his physics. Finally, using this chronological account of Newton’s use of actions at a distance, the paper re-assesses the claims of B. J. T. Dobbs that Newton’s important manuscript, De gravitatione et aequipondio fluidorum, was written, not in the late 1660s or early 1670s as was previously supposed, but during the composition of the Principia, in 1684 or 1685.Keywords: Isaac Newton; Action-at-a-distance; Gravity; Force; Aether; Attraction.

The rapidly changing field of genetics affects society through advances in health-care and through implications of genetic research. This study addresses the impacts of new genetic discoveries and technologies on different segments of today's society. The book begins with a chapter on genetic complexity, and subsequent chapters discuss moral and ethical questions arising from today's genetics from the perspectives of health care professionals, the media, the general public, special interest groups and commercial interests.

A striking feature of Newton’s thought is the very broad reach of his empiricism, potentially extending even to immaterial substances, including God, minds, and should one exist, a non-perceiving immaterial medium. Yet Newton is also drawn to certain metaphysical principles—most notably the principle that matter cannot act where it is not—and this second, rationalist feature of his thought is most pronounced in his struggle to discover ‘gravity’s cause’. The causal problem remains vexing, for he neither invokes primary causation, nor (...) accepts action at a distance by locating active powers in matter. To the extent that he is drawn to metaphysical principles, then, the causal problem is that of discovering some non-perceiving immaterial medium. Yet Newton’s thought has a third striking feature, one with roots in the other two: he allows that substances of different kinds might simultaneously occupy the very same region of space. I elicit the implications of these three features. For Newton to insist upon all three would transform the causal question about gravity into an insoluble problem about apportioning active powers. More seriously, it would undermine his means of individuating substances, provoking what I call ‘Newton’s Substance Counting Problem’. (shrink)

Philosophers of physics and physicists have long been intrigued by the analogies and disanalogies between gravitational theories and gauge theories. Indeed, repeated attempts to collapse these disanalogies have made us acutely aware that there are fairly general obstacles to doing so. Nonetheless, there is a special case space-time dimensions) in which gravity is often claimed to be identical to a gauge theory. I subject this claim to philosophical scrutiny in this article. In particular, I analyse how the standard disanalogies (...) can be overcome in dimensions, and consider whether really licenses the interpretation of gravity as a gauge theory. Our conceptual analysis reveals more subtle disanalogies between gravity and gauge, and connects these to interpretive issues in classical and quantum gravity. 1 Introduction1.1 Motivation1.2 Prospectus2 Disanalogies3 Three-dimensional gravity and gauge3.1 gravity3.2 Chern–Simons3.2.1 Cartan geometry3.2.2 Overcoming obst-gauge via Cartan connections3.3 Disanalogies collapsed4 Two More Disanalogies4.1 What about the symmetries?4.2 The phase spaces of the two theories5 Summary and Conclusion.

The central thesis of this paper is that contemporary theoretical physics is grounded in philosophical presuppositions that make it difficult to effectively address the problems of subject-object interaction and discontinuity inherent to quantum gravity. The core objectivist assumption implicit in relativity theory and quantum mechanics is uncovered and we see that, in string theory, this assumption leads into contradiction. To address this challenge, a new philosophical foundation is proposed based on the phenomenology of Maurice Merleau-Ponty and Martin Heidegger. Then, (...) through the application of qualitative topology and hypernumbers, phenomenological ideas about space, time, and dimension are brought into focus so as to provide specific solutions to the problems of force-field generation and unification. The phenomenological string theory that results speaks to the inconclusiveness of conventional string theory and resolves its core contradiction. (shrink)

In this essay, I examine the curved spacetime formulation of Newtonian gravity known as Newton–Cartan gravity and compare it with flat spacetime formulations. Two versions of Newton–Cartan gravity can be identified in the physics literature—a ‘‘weak’’ version and a ‘‘strong’’ version. The strong version has a constrained Hamiltonian formulation and consequently a well-defined gauge structure, whereas the weak version does not (with some qualifications). Moreover, the strong version is best compared with the structure of what Earman (World (...) enough and spacetime. Cambridge: MIT Press) has dubbed Maxwellian spacetime. This suggests that there are also two versions of Newtonian gravity in flat spacetime—a ‘‘weak’’ version in Maxwellian spacetime, and a ‘‘strong’’ version in Neo-Newtonian spacetime. I conclude by indicating how these alternative formulations of Newtonian gravity impact the notion of empirical indistinguishability and the debate over scientific realism. r 2004 Elsevier Ltd.
