This book, based on lectures, examines ways that the tradition of 'Middle' Platonism can point us to aspects of Plato's thinking which contemporary discussions often overlook, and which give us a better-rounded account of Plato.

BackgroundAn increasing number of studies utilize intracranial electrophysiology in human subjects to advance basic neuroscience knowledge. However, the use of neurosurgical patients as human research subjects raises important ethical considerations, particularly regarding informed consent and undue influence, as well as subjects’ motivations for participation. Yet a thorough empirical examination of these issues in a participant population has been lacking. The present study therefore aimed to empirically investigate ethical concerns regarding informed consent and voluntariness in Parkinson’s disease patients undergoing deep brain (...) stimulator (DBS) placement who participated in an intraoperative neuroscience study.MethodsTwo semi-structured 30-minute interviews were conducted preoperatively and postoperatively via telephone. Interviews assessed participants’ motivations for participation in the parent intraoperative study, recall of information presented during the informed consent process, and participants’ postoperative reflections on the research study.ResultsTwenty-two participants (mean age = 60.9) completed preoperative interviews at a mean of 7.8 days following informed consent and a mean of 5.2 days prior to DBS surgery. Twenty participants completed postoperative interviews at a mean of 5 weeks following surgery. All participants cited altruism or advancing medical science as “very important” or “important” in their decision to participate in the study. Only 22.7% (n = 5) correctly recalled one of the two risks of the study. Correct recall of other aspects of the informed consent was poor (36.4% for study purpose; 50.0% for study protocol; 36.4% for study benefits). All correctly understood that the study would not confer a direct therapeutic benefit to them.ConclusionEven though research coordinators were properly trained and the informed consent was administered according to protocol, participants demonstrated poor retention of study information. While intraoperative studies that aim to advance neuroscience knowledge represent a unique opportunity to gain fundamental scientific knowledge, improved standards for the informed consent process can help facilitate their ethical implementation.

This important new work surveys the source and ramifications of the famed Nuremburg Code -- recognized around the world as one of the cornerstones of modern bioethics.

Transient receptor potential vanilloid 4 (TRPV4), a member of the TRP superfamily, is a broadly expressed, cell surface‐localized cation channel that is activated by a variety of environmental stimuli. Importantly, TRPV4 has been increasingly implicated in the regulation of cellular morphology. Here we propose that TRPV4 and the cytoskeletal remodeling small GTPase RhoA together constitute an environmentally sensitive signaling complex that contributes to pathological cell cytoskeletal alterations during neurological injury and disease. Supporting this hypothesis is our recent work demonstrating direct (...) physical and bidirectional functional interactions of TRPV4 with RhoA, which can lead to activation of RhoA and reorganization of the actin cytoskeleton. Furthermore, a confluence of evidence implicates TRPV4 and/or RhoA in pathological responses triggered by a range of acute neurological insults ranging from stroke to traumatic injury. While initiated by a variety of insults, TRPV4–RhoA signaling may represent a common pathway that disrupts axonal regeneration and blood–brain barrier integrity. These insights also suggest that TRPV4 inhibition may represent a safe, feasible, and precise therapeutic strategy for limiting pathological TRPV4–RhoA activation in a range of neurological diseases.

The Borg are always confident that humans will be assimilated into their collective hive and therefore that, as they say, “resistance is futile.” In Star Trek, of course, the humans always successfully resist. Elizabeth Fenton and John Arras, like the Borg, resist the idea that humans are uniquely special as well as the utility of the human rights framework for global bioethics. I believe their resistance to human rights is futile, and I explain why in this essay. Let me begin (...) with their subtitle, because we do seem to agree that popular culture is a powerful aid to understanding human actions and motivations. (shrink)

Ideas about heredity and evolution are undergoing a revolutionary change. New findings in molecular biology challenge the gene-centered version of Darwinian theory according to which adaptation occurs only through natural selection of chance DNA variations. In Evolution in Four Dimensions, Eva Jablonka and Marion Lamb argue that there is more to heredity than genes. They trace four "dimensions" in evolution -- four inheritance systems that play a role in evolution: genetic, epigenetic, behavioral, and symbolic. These systems, they argue, can all (...) provide variations on which natural selection can act. Evolution in Four Dimensions offers a richer, more complex view of evolution than the gene-based, one-dimensional view held by many today. The new synthesis advanced by Jablonka and Lamb makes clear that induced and acquired changes also play a role in evolution.After discussing each of the four inheritance systems in detail, Jablonka and Lamb "put Humpty Dumpty together again" by showing how all of these systems interact. They consider how each may have originated and guided evolutionary history and they discuss the social and philosophical implications of the four-dimensional view of evolution. Each chapter ends with a dialogue in which the authors engage the contrarieties of the fictional "I.M.," or Ifcha Mistabra -- Aramaic for "the opposite conjecture" -- refining their arguments against I.M.'s vigorous counterarguments. The lucid and accessible text is accompanied by artist-physician Anna Zeligowski's lively drawings, which humorously and effectively illustrate the authors' points. (shrink)

Recently, scholars have looked more closely at the philosophical importance of the imaginative and literary aspects of Plato's writing, and have begun to appreciate the methods of ancient philosophers and commentators who studied Plato. This study brings together leading philosophical and literary scholars to investigate these new-old approaches.

Since at least the advent of Jack Kevorkian’s “suicide machine” the major argument against adopting physician-assisted suicide laws has been that they will lead us down a slippery slope to state-sa...

ABSTRACT:A wide range of research uses patterns of genetic variation to infer genetic similarity between individuals, typically referred to as genetic ancestry. This research includes inference of human demographic history, understanding the genetic architecture of traits, and predicting disease risk. Researchers are not just structuring an intellectual inquiry when using genetic ancestry, they are also creating analytical frameworks with broader societal ramifications. This essay presents an ethics framework in the spirit of virtue ethics for these researchers: rather than focus on (...) rule following, the framework is designed to build researchers’ capacities to react to the ethical dimensions of their work. The authors identify one overarching principle of intellectual freedom and responsibility, noting that freedom in all its guises comes with responsibility, and they identify and define four principles that collectively uphold researchers’ intellectual responsibility: truthfulness, justice and fairness, anti-racism, and public beneficence. Researchers should bring their practices into alignment with these principles, and to aid this, the authors name three common ways research practices infringe these principles, suggest a step-by-step process for aligning research choices with the principles, provide rules of thumb for achieving alignment, and give a worked case. The essay concludes by identifying support needed by researchers to act in accord with the proposed framework. (shrink)

When interpreting the meanings of visual features in information visualizations, observers have expectations about how visual features map onto concepts (inferred mappings.) In this study, we examined whether aspects of inferred mappings that have been previously identified for colormap data visualizations generalize to a different type of visualization, Venn diagrams. Venn diagrams offer an interesting test case because empirical evidence about the nature of inferred mappings for colormaps suggests that established conventions for Venn diagrams are counterintuitive. Venn diagrams represent classes (...) using overlapping circles and express logical relationships between those classes by shading out regions to encode the concept of non-existence, or none. We propose that people do not simply expect shading to signify non-existence, but rather they expect regions that appear as holes to signify non-existence (the hole hypothesis.) The appearance of a hole depends on perceptual properties in the diagram in relation to its background. Across three experiments, results supported the hole hypothesis, underscoring the importance of configural processing for interpreting the meanings of visual features in information visualizations.

The law has therefore had two conflicting impacts on medical ethics: the positive effect of eroding paternalism and replacing it with a patient-centered ethic; and the negative effect of encouraging physicians to be more concerned with avoiding litigation than doing the "right" thing.

Both experimental and therapeutic uses of the new reproductive technologies have been governed not by the medical ideology of the best interests of patients and their children, but by the market ideology of profit maximization under the guise of "reproductive liberty." Government in our constitutional, democratic society has the authority and obligation to make and enforce reasonable regulations to manage the new reproductive market in order to protect the interests of the public, prospective parents, and their future children. The "cloning" (...) debate provides a useful opportunity to compare and contrast the competing regulatory models of the free market, professional guidelines, and government restrictions. (shrink)

In his compelling novel Blindness, José Saramago tells us about victims stricken by a contagious form of blindness who were quarantined and came to see themselves as pigs, dogs, and “lame crabs.” Of course, they were all human beings - although unable to perceive themselves, or others, as members of the human community. The disciplines of bioethics, health law, and human rights are likewise all members of the broad human rights community, although at times none of them may be able (...) to see the homologies, even when responding to a specific health challenge.The boundaries between bioethics, health law, and human rights are permeable, and border crossings, including crossings by blind practitioners, are common. Two working hypotheses form the intellectual framework of this article: we can more effectively address the major health issues of our day if we harmonize all three disciplines; and American bioethics can be reborn as a global force by accepting its Nuremberg roots and actively engaging in a health and human rights agenda.

With this issue George Annas contributes his last At Law to the Hastings Center Report. Since the column was inaugurated in 1976 as Law and the Life Sciences, George has charted the course of biomedical ethics in the courts, challenging readers to come to grips with an emerging body of law in provocative analyses of critical decisions. As he retires from this column we wish him well, and look forward to his continued contributions to our pages. In bidding farewell (...) to one friend we are nonetheless pleased to welcome another as Alexander Morgan Capron, Henry W. Bruce University Professor of Law and Medicine at the University of Southern California and codirector of the Pacific Center for Health Policy and Ethics, joins the Report in the September‐October issue as a regular contributor to this column. Prof. Capron, formerly executive director of The President's Commission for the Study of Ethical Problems in Medicine and Biomedical and Behavioral Research, is a distinguished scholar and writer well known to our readers. We welcome the opportunity to share his insights on issues before courts and legislatures nationwide. (shrink)

Only 27 percent of Americans in a 1995 Harris poll said they had read or heard “quite a lot” about genetic tests. Nonetheless, 68 percent said they would be either “very likely” or “somewhat likely” to undergo genetic testing even for diseases “for which there is presently no cure or treatment.” Perhaps most astonishing, 56 percent found it either “very” or “somewhat acceptable” to develop a government computerized DNA bank with samples taken from all newborns, and their names attached to (...) the samples. This does not necessarily mean the public is unconcerned about genetic privacy. More likely it means that the public is still uninformed about the risks associated with genetic testing, and has not thought at all about the risks involved in storing identifiable DNA samples.A central question presented by genetic screening and testing is whether the genetic information so obtained is different in kind from other medical information, and, if so, whether this means that it should receive special legal protection.

The authors proposes a philosophical hinterland of nomological type for various conceptions of alethic modalities. Differences among these conceptions are explained by the fact, that moda­lizators can be relativized to various types of laws. Thus one can speak respectively about logic and definitional, ontical and physical, technical and dispositional, psychological and methodo­logical, and finally deontic modalities. The authors shows that in their conceptual appa­ratus modal logics find intuitive interpretation more clear and ontologically more cautious than the semantics of possible worlds (...) philosophically interpreted. The nomological explication of main notions of this semantics (like “possible world” and “accessibility relation”) is also given. (shrink)
