The public largely supports the use of animals in biomedical research, but only if they are sure that the animals are treated humanely. The scientific community has provided these assurances. Is this a truthful claim? I argue that when examined systematically, the claim that animals in research are treated humanely is not truthful by any existing definition of the word. This article does not argue for or against the morality of using animals in research; rather, the reasoning set forth herein (...) argues that in this use of animals, the scientific community is not being truthful to the public.

The consistency of a second-order version of Morley’s Theorem on the number of countable models was proved in [EHMT23] with the aid of large cardinals. We here dispense with them.

Keywords: Elementary Submodel; Real Line; Order-Isomorphic.

Since their public launch, a little over a year ago, large language models (LLMs) have inspired a flurry of analysis about what their implications might be for medical ethics, and for society more broadly. 1 Much of the recent debate has moved beyond categorical evaluations of the permissibility or impermissibility of LLM use in different general contexts (eg, at work or school), to more fine-grained discussions of the criteria that should govern their appropriate use in specific domains or towards certain (...) ends. 2 With each passing week, it seems more and more inevitable that LLMs will be a pervasive feature of many, if not most, of our lives. It would not be possible—and would not be desirable—to prohibit them across the board. We need to learn how to live with LLMs; to identify and mitigate the risks they pose to us, to our fellow creatures, and the... (shrink)

By utilizing the topological concept of pseudocompactness, we simplify and improve a proof of Caicedo, Dueñez, and Iovino concerning Terence Tao's metastability. We also pinpoint the exact relationship between the Omitting Types Theorem and the Baire Category Theorem by developing a machine that turns topological spaces into abstract logics.

Given a space in an elementary submodel M of H, define XM to be X∩M with the topology generated by . It is established, using anti-large-cardinals assumptions, that if XM is compact and its regular open algebra is isomorphic to that of a continuous image of some power of the two-point discrete space, then X=XM. Assuming in addition, the result holds for any compact XM satisfying the countable chain condition.

In lieu of an abstract, here is a brief excerpt of the content:The Incoherence of Determining Death by Neurological Criteria: A Commentary on Controversies in the Determination of Death, A White Paper by the President’s Council on Bioethics*Franklin G. Miller** (bio) and Robert D. Truog (bio)Traditionally the cessation of breathing and heart beat has marked the passage from life to death. Shortly after death was determined, the body became a cold corpse, suitable for burial or cremation. Two technological changes (...) in the second half of the twentieth century prompted calls for a new, or at least expanded, definition of death: the development of intensive care medicine, especially the use of mechanical ventilators, and the advent of successful transplantation of vital organs. Patients with profound neurological damage, leaving them incapable of breathing on their own and in an irreversible coma, could be maintained for some period of time with the aid of mechanical ventilation. The situation of these patients posed two ethical questions. Is it appropriate to stop life-sustaining treatment? If so, is it acceptable to retrieve vital organs for transplantation to save the lives of others before stopping treatment?In 1968, the Ad Hoc Committee of the Harvard Medical School to Examine the Definition of Brain Death proposed that death could be determined on the basis of neurological criteria, thus providing a positive answer to these two questions (Ad Hoc Committee 1968). According to the position of this committee, patients diagnosed with the cessation of brain function are dead, despite the fact that they breathe and circulate blood with the aid of mechanical ventilation. [End Page 185] Because they are dead, it is appropriate, indeed imperative, to stop mechanical ventilation. And because they are dead, it becomes ethical to procure vital organs for transplantation before stopping what otherwise would be life-sustaining treatment. Remarkably, this innovative neurological determination of death became, with little debate or controversy, the established position in medical ethics and the law throughout the United States.The Harvard Committee articulated the diagnosis of “irreversible coma,” but merely asserted that this condition constituted death. No explanatory rationale was provided. It fell to the President’s Commission for the Study of Ethical Problems in Medicine and Biomedical and Behavioral Research to provide an authoritative rationale in its 1981 report, Defining Death. The second paragraph of the report set the stage as follows: “The question addressed here is not inherently difficult or complicated. Simply, it is whether the law ought to recognize new means for establishing that the death of a human being has occurred” (President’s Commission 1981, p. 3). The Commission claimed that “death is a unitary phenomenon” (p. 7) and that the determination of death by neurological criteria, in terms of the absence of all brain function, is consistent with the traditional conception of death as the cessation of vital functioning of the organism as a whole. The key issue is the integrative functioning of the human organism, which ceases to exist, according to the Commission, when the whole brain, including higher cortical areas and the brain stem, fails to function. Although “brain-dead” patients do not appear to be dead—i.e., the reality of their death is “masked” by the activity of mechanical ventilation—the patient’s body has irreversibly lost all capacity for integrative functioning. In the words of the Commission: “When artificial means of support mask this loss of integration as measured by the old methods [cessation of respiration and heart beat], brain-oriented criteria and tests provide a new window on the same phenomenon” (p. 33). The President’s Commission was instrumental in developing and establishing “The Uniform Definition of Death Act”: “An individual who has sustained either (1) irreversible cessation of circulatory and respiratory functions, or (2) irreversible cessation of all functions of the entire brain, including the brain stem, is dead” (p. 2).Although the question posed by the President’s Commission was easy to articulate, the answer, over time, has proved complicated and controversial. The coherence and cogency of determining death by neurological criteria has been challenged. Various experts have demonstrated that “brain-dead” patients maintained on mechanical ventilation display a range of vital, integrative, functioning, which conflicts with the judgment that they are dead (Truog and...

Accepted medical practice already violates the dead donor rule. Explicitly jettisoning the rule—allowing vital organs to be extracted, under certain conditions, from living patients—is a radical change only at the conceptual level. But it would expand the pools of eligible organ donors.

Conventional medical ethics and the law draw a bright line distinguishing the permitted practice of withdrawing life-sustaining treatment from the forbidden practice of active euthanasia by means of a lethal injection. When clinicians justifiably withdraw life-sustaining treatment, they allow patients to die but do not cause, intend, or have moral responsibility for, the patient's death. In contrast, physicians unjustifiably kill patients whenever they intentionally administer a lethal dose of medication. We argue that the differential moral assessment of these two practices (...) is based on a series of moral fictions – motivated false beliefs that erroneously characterize withdrawing life-sustaining treatment in order to bring accepted end-of-life practices in line with the prevailing moral norm that doctors must never kill patients. When these moral fictions are exposed, it becomes apparent that conventional medical ethics relating to end-of-life decisions is radically mistaken. (shrink)

Bioethics is a hybrid discipline. As a theoretical enterprise it stands for untrammeled inquiry and argument. Yet it aims to influence medical practice and policy. In this article we explore tensions between these two dimensions of bioethics and examine the merits and perils of a “Socratic” approach to bioethics that challenges “the conventional wisdom.”.

This book challenges fundamental doctrines of established medical ethics. It is argued that the routine practice of stopping life support technology causes the death of patients and that donors of vital organs (hearts, liver, lungs, and both kidneys) are not really dead at the time that their organs are removed for life-saving transplantation. Although these practices are ethically legitimate, they are not compatible with traditional medical ethics: they conflict with the norms that doctors must not intentionally cause the death of (...) their patients and that vital organs can be obtained only from dead donors. The aim of this book is to undertake an ethical examination that aims to honestly face the reality of medical practices at the end of life. This involves exposing the misconception that stopping life support merely allows patients to die from their medical conditions, that there is an ethical bright line separating withdrawal of life support from active euthanasia, and that determination of death of hospitalized patients prior to vital organ donation is consistent with the established biological conception of death. A novel ethical justification is required for procuring vital organs from still-living donors. It is contended that in the context of plans to withdraw life support, donors of vital organs are not harmed or wronged by organ procurement prior to death, provided that valid consent is obtained for stopping treatment and organ donation. In view of serious practical difficulties in facing the truth regarding organ donation, an alternative pragmatic account is developed for justifying current practices that relies on the concept of transparent legal fictions. In sum, it is the thesis of this book that to preserve the legitimacy of end-of-life practices, we need to reconstruct medical ethics. (shrink)

Socially responsible publishers, such as the BMJ Publishing Group, have demonstrated a commitment to health equity and working towards rectifying the structural racism that exists both in healthcare and in medical publishing.1 The commitment of academic publishers to collecting information relevant to promoting equity and diversity is important and commendable where it leads to that result.2 However, collecting sensitive demographic data is not a morally neutral activity. Rather, it carries with it both known and potential risks. Among these are issues (...) around privacy or data misuse, as well as more basic concerns about how, when or why people should be categorised in certain ways and/or prompted to conceive of themselves or their identities in certain terms.3 If such data are to be collected, therefore, their effectiveness in achieving the stated ends must have a sufficiently compelling evidence base so as to justify the various risks involved. And where possible, these risks must also be identified and minimised. As Varcoe et al 4 argue, > While most leaders and healthcare workers and some patients [in their study] envisioned potential benefits associated with having ethnicity data, these benefits were seen as largely contingent upon action being taken to [actually] ameliorate inequities. Overwhelmingly, however, leaders from ethno-cultural communities and patients of diverse identities anticipated potential harm arising both from having ethnicity data and the process of collection. The analysis illustrates that in today’s sociopolitical context, collecting ethnicity data in clinical contexts may engender considerable harm, particularly for racialized, vulnerable patients. (p1569) Varcoe et al refer to ‘ethnicity’ data, which as they note is an ambiguous concept, potentially encompassing such diverse notions as ancestry, language, religion or culture. It is also a term that is in some contexts—for example, the USA—often used interchangeably with a different, more highly charged term: ‘race’. Data …. (shrink)

The currently leading cognitive theory of consciousness, Global Workspace Theory,1,2 postulates that the primary functions of consciousness include a global broadcast serving to recruit internal resources with which to deal with the current situation and to modulate several types of learning. In addition, conscious experiences present current conditions and problems to a "self" system, an executive interpreter that is identifiable with brain structures like the frontal lobes and precuneus.1Be it human, animal or artificial, an autonomous agent3 is said to be (...) functionally conscious if its control structure (mind) implements Global Workspace Theory and the LIDA Cognitive Cycle, which includes unconscious memory and control functions needed to integrate the conscious component of the system. We would therefore consider humans, many animals4 and even some virtual or robotic agents5,6 to be functionally conscious. Such entities may approach phenomenal consciousness, as found in human and other biological brains, as additional brain-like features are added.Here we argue that adding mechanisms to produce a stable, coherent perceptual field7 in a LIDA controlled mobile robot might provide a small but significant step toward phenomenal consciousness in machines.>8 We also propose that implementing several of the various notions of self in such a LIDA controlled robot may well prove another step toward phenomenal consciousness in machines.

Drawing on a recent case report of a pregnant, brain‐dead woman who gave birth to a healthy child after over seven months of intensive care treatment, this essay rejects the established doctrine in medicine that brain death constitutes the biological death of the human being. The essay describes three policy options with respect to determination of death and vital organ transplantation in the case of patients who are irreversibly comatose but remain biologically alive.

We seek to change the conversation about brain death by highlighting the distinction between brain death as a biological concept versus brain death as a legal status. The fact that brain death does not cohere with any biologically plausible definition of death has been known for decades. Nevertheless, this fact has not threatened the acceptance of brain death as a legal status that permits individuals to be treated as if they are dead. The similarities between “legally dead” and “legally blind” (...) demonstrate how we may legitimately choose bright-line legal definitions that do not cohere with biological reality. Not only does this distinction bring conceptual coherence to the conversation about brain death, but it has practical implications as well. Once brain death is recognized as a social construction not grounded in biological reality, we create the possibility of changing the social construction in ways that may better serve both organ donors and recipients alike.

Fluctuations in attentional state and their relation to goal neglect were examined in the current study. Participants performed a variant of the Stroop task in which attentional state ratings were given prior to each trial. It was found that pre-trial attentional state ratings predicted subsequent trial performance, such that when participants rated their current attentional state as highly focused on the current task, performance tended to be high compared to when participants reported their current attentional state as being unfocused on (...) the current task. This effect was larger for incongruent than congruent trials leading to differences in the magnitude of the Stroop effect as a function of pre-trial attentional state. Furthermore, variability in attentional state was correlated with overall levels of performance, and when attentional state was covaried out, the Stroop effect was greatly reduced. These results suggest a link between fluctuations in pre-trial attentional state and goal neglect. (shrink)

Mood disorders, including major depressive disorder and bipolar disorder, are highly prevalent, frequently disabling, and sometimes deadly. Additional research and more effective medications are desperately needed, but clinical trials research in mood disorders is fraught with ethical issues. Although many authors have discussed these issues, most do so from a theoretical viewpoint. This manuscript uses available empirical data to inform a discussion of the primary ethical issues raised in mood disorders research. These include issues of consent and decision-making capacity, including (...) patients’ motivations for participating in research. We also address drug withdrawals, placebo controls, and the overall safety of research. Finally, we examine the extant literature for studies discussing potential indirect benefits of clinical trials research to participants. Taken together, the evidence suggests that clinical trials research incorporating drug withdrawals and placebo controls can be conducted safely and ethically, even in patients with severe or treatment-resistant mood disorders. In fact, given the dearth of effective treatment options for this population, it is our opinion that a moral imperative exists to extend the offer of research participation to severely ill or treatment-resistant groups.

Controversies about the diagnosis and meaning of brain death have existed as long as the concept itself. Here we review the historical development of brain death, and then evaluate the various attempts to justify the claim that patients who are diagnosed as brain dead can be considered dead for all legal and social purposes, and especially with regard to procuring their vital organs for transplantation. While we agree with most commentators that death should be defined as the loss of integration (...) of the functioning of the organism as a whole, we conclude that patients diagnosed as brain dead have not, in fact, lost this integrated functioning. We close with reflections on the implications of this conclusion generally and particularly with regard to organ transplantation, and briefly make reference to alternative approaches to justifying the procurement of transplantable organs that do not depend upon a flawed approach to the diagnosis of death.

Human life and death should be defined biologically. It is important not to conflate the definition of death with the criteria for when it has occurred. What is distinctively "human" from a scientific or normative perspective has nothing to do with what makes humans alive or dead. We are biological organisms, despite the fact that what is meaningful about human life is not defined in biological terms. Consequently, as in the rest of the realm of living beings, human beings die (...) when they no longer function biologically as organisms. In contrast, a determination of exactly when death has occurred, required to serve various social purposes, combines social and normative considerations with biological facts. (shrink)

The COVID-19 pandemic will generate vexing ethical issues for the foreseeable future and many journals will be open to content that is relevant to our collective effort to meet this challenge. While the pandemic is clearly the critical issue of the moment, it’s important that other issues in medical ethics continue to be addressed as well. As can be seen in this issue, the Journal of Medical Ethics will uphold its commitment to publishing high quality papers on the full array (...) of medical ethics. At the same time, JME aims to be a premiere home for ground-breaking scholarship on the ethical issues raised by COVID-19.

: This response to Lynn Jansen's critique of clinical pragmatism concentrates on two themes: (1) contrasting approaches to moral epistemology and (2) the connection between theory and practice in clinical ethics. Particular attention is paid to the status of principles and the role of consensus, with some closing speculations on how Dewey might view the current state of bioethics.

We perceive color everywhere and on everything that we encounter in daily life. Color science has progressed to the point where a great deal is known about the mechanics, evolution, and development of color vision, but less is known about the relation between color vision and psychology. However, color psychology is now a burgeoning, exciting area and this Handbook provides comprehensive coverage of emerging theory and research. Top scholars in the field provide rigorous overviews of work on color categorization, color (...) symbolism and association, color preference, reciprocal relations between color perception and psychological functioning, and variations and deficiencies in color perception. The Handbook of Color Psychology seeks to facilitate cross-fertilization among researchers, both within and across disciplines and areas of research, and is an essential resource for anyone interested in color psychology in both theoretical and applied areas of study.

Although informed consent is important in clinical research, questions persist regarding when it is necessary, what it requires, and how it should be obtained. The standard view in research ethics is that the function of informed consent is to respect individual autonomy. However, consent processes are multidimensional and serve other ethical functions as well. These functions deserve particular attention when barriers to consent exist. We argue that consent serves seven ethically important and conceptually distinct functions. The first four functions pertain (...) principally to individual participants: (1) providing transparency; (2) allowing control and authorization; (3) promoting concordance with participants' values; and (4) protecting and promoting welfare interests. Three other functions are systemic or policy focused: (5) promoting trust; (6) satisfying regulatory requirements; and (7) promoting integrity in research. Reframing consent around these functions can guide approaches to consent that are context sensitive and that maximize achievable goals. (shrink)
