The Deaf culture in the United States is a unique culture that is not widely understood. To members of the Deaf community in the United States, deafness is not viewed as a disease or pathology to be treated or cured; instead it is seen as a difference in human experience. Members of this community do not hide their deafness; instead they take great pride in their Deaf identity. The Deaf culture in the United States is very communitarian not individualistic. Mary (...) Beth and Dominic are a married couple in their late 20s who are genetically deaf. They are active members in the Deaf community and work as advocates for individuals who are deaf, family members of Deaf people and sign language interpreters who identify with the Deaf culture. Mary Beth and Dominic approach the fertility clinic with a request that they only want a child with the genetic gene for deafness. They would want the embryos that do not have the gene to be destroyed. This would entail creating a child who would have the gene for deafness. Medically and ethically, should the fertility clinic agree to the couple’s request? The authors argue that the couple's request should be denied and provide reasons for it from the perspectives of foundational and clinical ethics. (shrink)

This piece presents the work of academics and architects in a collaborative venture. It provides an architectural design and a series of statements towards the hypothetical creation of an unconventional city centre in the Chinese city of Shenzhen. The idea is to create a linear university that would run the 20-kilometer length of the Shenzhen Strip: the 20K university. The contributors outline, in the diversity of their idioms, a complex spatial condition fundamental to life, and demonstrate new relationships between knowledge (...) and the city. The design of the proposed ‘open university space’ responds to two simultaneous and interrelated challenges: that posed to architecture, and that posed to science. The university would embody the meeting of these at the intersection of the urban infrastructure and the knowledge infrastructure. The purpose is thus also to develop the notion of knowledge, embodied in institutions, as urban infrastructure. (shrink)

The statistical properties of a single quantum object and an ensemble of independent such objects are considered in detail for two-level systems. Computer simulations of dynamic zero-point quantum fluctuations for a single quantum object are reported and compared with analytic solutions for the ensemble case.

This paper provides a critical reconstruction of J. B. Erhard's account of recognition that locates it within the context of his revolutionary natural law theory. The first three sections lay out the foundations of Erhard's position. The fourth section outlines Erhard's response to the opponents of revolution and raises a problem for it. The fifth section argues that we can resolve this problem by drawing upon Erhard's account of failures of legal recognition. The sixth and final section considers the relevance (...) of that account for contemporary legal and political theory. (shrink)

The ability to make direct genetic changes to the DNA of future children poses profound challenges for governance: should it be done? For what purposes and subject to what limitations? And, no less importantly, who should decide? As a resolution pending in the US Senate rightly states, the prospect of editing the germline "touches on all of humanity". Given this, how should we as a human community guide and govern this emerging technology?The question of how human genome editing should be (...) governed—and by whom—has been at the heart of the debates that have unfolded over the course of the last five years....

On April 3, 2015, a group of prominent biologists and ethicists called for a worldwide moratorium on human genetic engineering in which the genetic modifications would be passed on to future generations. Describing themselves as “interested stakeholders,” the group held a retreat in Napa, California, in January to “initiate an informed discussion” of CRISPR/Cas9 genome engineering technology, which could enable high-precision insertion, deletion, and recoding of genes in human eggs, sperm, and embryos. The group declared that the advent of a (...) technology that makes human germ-line genetic engineering plausible makes a corollary discussion of its ethical implications urgent. Echoing this sentiment, the National Academy of Sciences and the National Academy of Medicine have announced plans to convene an international summit in fall 2015 to assess the implications of CRISPR/Cas9. Yet the notion that the advent of this particular technology is the warrant for initiating a public discussion is remarkable, and so too is the idea that the experts who have brought it into being and are putting it to use are best positioned to define the terms of the debate. The relevant ethical questions are by no means specific, let alone subsidiary, to the CRISPR/Cas9 technology. They are longstanding questions about what features of human life ought not be taken as objects of manipulation and control. They are questions about our responsibilities to our children and our children's children, where the mark of our actions will be inscribed upon their bodies and their lives. (shrink)

This paper examines political norms and relationships associated with governance of pandemic risk. Through a pair of linked controversies over scientific access to H5N1 flu virus and genomic data, it examining the duties, obligations, and allocations of authority articulated around the imperative for globally free-flowing information and around the corollary imperative for a science that is set free to produce such information. It argues that scientific regimes are laying claim to a kind of sovereignty, particularly in moments where scientific experts (...) call into question the legitimacy of claims grounded in national sovereignty, by positioning the norms of scientific practice, including a commitment to unfettered access to scientific information and to the authority of science to declare what needs to be known, as essential to global governance. Scientific authority occupies a constitutional position insofar as it figures centrally in the repertoire of imaginaries that shape how a global community is imagined: what binds that community together and what shared political commitments, norms, and subjection to delegated authority are seen as necessary for it to be rightly governed.

When looking at a scene, observers feel that they see its entire structure in great detail and can immediately notice any changes in it. However, when brief blank fields are placed between alternating displays of an original and a modified scene, a striking failure of perception is induced: identification of changes becomes extremely difficult, even when changes are large and made repeatedly. Identification is much faster when a verbal cue is provided, showing that poor visibility is not the cause of (...) this difficulty. Identification is also faster for objects mentioned in brief verbal descriptions of the scene. These results support the idea that observers never form a complete, detailed representation of their surroundings. In addition, results also indicate that attention is required to perceive change, and that in the absence of localized motion signals it is guided on the basis of high-level interest. (shrink)

This paper concerns the relationship between epistemology and radically extended cognition. Radically extended cognition (REC) – as advanced by Andy Clark and David Chalmers – is cognition that is partly located outside the biological boundaries of the cognizing subject. Epistemologists have begun to wonder whether REC has any consequences for theories of knowledge. For instance, while Duncan Pritchard suggests that REC might have implications for which virtue epistemology is acceptable, J. Adam Carter wonders whether REC threatens anti-luck epistemology. In this (...) paper, I argue that the possibility of REC has no systematic consequences for theorizing in epistemology. I suggest an alternative relationship between the two: epistemology can play a role in diagnosing cases of REC. Thus, by establishing that entities partially located outside biological boundaries don't play certain epistemic roles, one can establish that they don't play the related cognitive roles either. I conclude the paper by illustrating this last point. (shrink)

Strange inversions occur when things work in ways that turn received wisdom upside down. Hume offered a strangely inverted story about causation, and Darwin, about apparent design. Dennett suggests that a strange inversion also occurs when we project our own reactive complexes outward, painting our world with elusive properties like cuteness, sweetness, blueness, sexiness, funniness, and more. Such properties strike us as experiential causes, but they are really effects—a kind of shorthand for whole sets of reactive dispositions rooted in the (...) nuts and bolts of human information processing. Understanding the nature and origins of that strange inversion, Dennett believes, is thus key to understanding the nature and origins of human experience itself. This paper examines this claim, paying special attention to recent formulations that link that strange inversion to the emerging vision of the brain as a Bayesian estimator, constantly seeking to predict the unfolding sensory barrage.

Biobanks are custodial institutions that enhance the utility and value of biological materials by collecting and curating them. Their custodial functions tend to include ethical oversight and governance. This paper explores how biobanks increase the value of biological materials by standardizing routines of governance in order to engender “ethical efficiency.” Focusing in particular upon banking of human embryos for research, the article offers an historical account of how human embryos came to be “waste” available for use by researchers in the (...) US. It offers a case study of a human embryo biobank and the practices of ethical governance that the biobank employs to capture this waste and convert it into a valuable resource for research use. The article draws attention to the ways biobanks’ emphasis on efficiency and resolving problems of ethical governance up front codifies otherwise contested normative relationships and authorizes uses of human biological materials that some see as ethically problematic, even as it eliminates institutionalized mechanisms of reflection in which such problems would otherwise be acknowledged and confronted.

Extended Cognition examines the way in which features of a subject's cognitive environment can become constituent parts of the cognitive process itself. This volume explores the epistemological ramifications of this idea, bringing together academics from a variety of different areas, to investigate the very idea of an extended epistemology.

Humans have always imagined better futures. From the desire to overcome death to the aspiration to dominion over the world, imaginations of the technological future reveal the commitments, values, and norms of those who construct them. Today, the human future is thrown into question by emerging technologies that promise radical control over human life and elicit corollary imaginations of human perfectibility. This interdisciplinary volume assembles scholars of science and technology studies, sociology, philosophy, theology, ethics, and history to examine imaginations of (...) technological progress that promises to transcend the constraints of human body and being. Attending in particular to transhumanist and posthumanist visions, the volume breaks new ground by exploring their utopian and eschatological dimensions and situating them within a broader context of ideas, institutions, and practices of innovation. The volume invites specialists and general readers to explore the stakes of contemporary imaginations of technological innovation as a source of progress, a force of social and historical transformation, and as the defining essence of human life.

As Achim Rosemann and colleagues rightly suggest in their article “Heritable Genome Editing in Global Context: National and International Policy Challenges,” in this issue of the Hastings Center Report, the scientific, ethical, and governance challenges associated with heritable genome editing are global in scope. Both the genetic interventions and the social and moral judgments about human identity and integrity associated with them will affect all humanity. Yet the worries, problems, and solutions that the study illuminates reflect only a partial picture (...) of those challenges. That is to be expected from a study of this sort: the “stakeholders” who were consulted are a limited group and as such are bound to provide a particular, limited picture. One of the important contributions that such a study can make is in providing a picture of what problems particular kinds of experts see as the primary problems and how the framing of those problems may displace other questions and perspectives, especially when such parochial framings of problems are elevated to the level of the “global.” Rosemann et al. do not explain how participants were identified as stakeholders or, indeed, how the study identified the stakes. This is a missed opportunity, and it points toward a set of questions that themselves need to be asked about how the stakeholders—and the stakes—of global governance of heritable genome editing are identified.

If our choices make us who we are, then what does that mean when these choices are made in the human-machine interface? Developing a clear understanding of how human decision making is influenced by automated systems in the environment is critical because, as human-machine interfaces and assistive robotics become even more ubiquitous in everyday life, many daily decisions will be an emergent result of the interactions between the human and the machine – not stemming solely from the human. For example, (...) choices can be influenced by the relative locations and motor costs of the response options, as well as by the timing of the response prompts. In drift diffusion model simulations of response-prompt timing manipulations, we find that it is only relatively equibiased choices that will be successfully influenced by this kind of perturbation. However, with drift diffusion model simulations of motor cost manipulations, we find that even relatively biased choices can still show some influence of the perturbation. We report the results of a two-alternative forced-choice experiment with a computer mouse modified to have a subtle velocity bias in a pre-determined direction for each trial, inducing an increased motor cost to move the cursor away from the pre-designated target direction. With queries that have each been normed in advance to be equibiased in people’s preferences, the participant will often begin their mouse movement before their cognitive choice has been finalized, and the directional bias in the mouse velocity exerts a small but significant influence on their final choice. With queries that are not equibiased, a similar influence is observed. By exploring the synergies that are developed between humans and machines and tracking their temporal dynamics, this work aims to provide insight into our evolving decisions. (shrink)

This volume explores the epistemology of distributed cognition, the idea that groups of people can generate cognitive systems that consist of all participating members. Can distributed cognitive systems generate knowledge in a similar way to individuals? If so, how does this kind of knowledge differ from normal, individual knowledge?

First, a theoretical background to the volume’s topic, extended epistemology, is provided by a brief outline of its cross-disciplinary theoretical lineage and some key themes. In particular, it is shown how and why the emergence of recent and more egalitarian thinking in the cognitive sciences about the nature of human cognizing and its bounds—viz., the so-called ‘extended cognition’ program, and the related idea of an ‘extended mind’—has important and interesting ramifications in epistemology. Second, an overview is provided of the papers (...) included as chapters in the volume. The sixteen contributions are divided into two categories: those that engage with foundational issues to do with extended epistemology, and those that pursue applications of extended epistemology to new areas of research.

In this paper, we discuss the macroscopic quantum behavior of simple superconducting circuits. Starting from a Lagrangian for electromagnetic field with broken gauge symmetry, we construct a quantum circuit model for a superconducting weak link (SQUID) ring, together with the appropriate canonical commutation relations. We demonstrate that this model can be used to describe macroscopic excitations of the superconducting condensate and the localized charge states found in some ultrasmall-capacitance weak-link devices.

High-spin states have been studied in Pr-135(59), populated through the Cd-116(Na-23,4n) reaction at 115 MeV, using the Gammasphere gamma-ray spectrometer. The negative-parity yrast band has been significantly extended to spin similar to 45 (h) over bar and excitation energy 21.5 MeV, showing evidence for several rotational alignments. The positive-parity yrast band of Ce-135(58), populated through the p4n channel of this reaction, was also populated to spin similar to 38 (h) over bar and excitation energy 18 MeV. Cranking calculations indicate that (...) these nuclei are soft with respect to the triaxiality parameter gamma and that several competing nuclear shapes occur at high spin. (shrink)

Medium- and high-spin states of Pr-134 were populated using the Cd-116(Na-23, 5n) reaction and studied with the GAMMASPHERE spectrometer. Several new bands have been found in this nucleus, one of them being linked to the previously observed chiral-candidate twin-band structure. The ground state of Pr-134 could be determined through establishing a level structure that connects the two previously known long-lived isomeric states. Unambiguous spin-parity assignments for the excited states could be performed based on the known 2(-) spin-parity of the ground (...) state combined with the present experimental data. Intrinsic single-particle configurations have been assigned to the newly observed bands on the basis of the measured B(M1)/B(E2) ratios, alignments, band-crossing frequencies, bandhead spins, the observed single-particle configurations in the neighboring nuclei, and taking into account the predictions of total Routhian surface and tilted-axis cranking calculations.

This is the first of two volumes of essays in commemoration of Alan Turing, whose pioneering work in the theory of artificial intelligence and computer science continues to be widely discussed today. A group of prominent academics from a wide range of disciplines focus on three questions famously raised by Turing: What, if any, are the limits on machine `thinking'? Could a machine be genuinely intelligent? Might we ourselves be biological machines, whose thought consists essentially in nothing more than the (...) interaction of neurons according to strictly determined rules? The discussion of these fascinating issues is accessible to non-specialists and stimulating for all readers. (shrink)

This chapter explores the tension between public health protection and the freedom of commercial expression from a Commonwealth Caribbean perspective, using Barbados and Jamaica as case studies. First, it assesses the scope of the right to freedom of expression. Second, it discusses the extent to which public health protection may be invoked to restrict the right. The authors conclude that Commonwealth Caribbean states can justifiably restrict commercial speech about tobacco products and unhealthy food and beverages.

An international team of ethicists refresh the debate about human enhancement by examining whether resistance to the use of technology to enhance our mental and physical capabilities can be supported by articulated philosophical reasoning, or explained away, e.g. in terms of psychological influences on moral reasoning.

Science, Truth, and Meaning presents a scientific and philosophical examination of our place in the world. It also celebrates how diverse, scientific knowledge is interconnected and reducible to common foundations.The book focuses on aspects of scientific truth that relate to our understanding of reality, and confronts whether truth is absolute or relative to what we are. Hence, it assesses the meaning of the scientific deductions we have made and how they have profoundly influenced our conception of life and existence.The subtitle (...) is 'From Wonder to Understanding', which is a paraphrased quote from Einstein, who said that the search for scientific truth is '... a continual flight from wonder to understanding'.In addressing the goal of advancing our understanding of our place in the world, this book also reveals the development and details of diverse sciences, their connections and achievements, and that while perhaps the same fundamental questions exist, they are seen in the light of an ever-refined scientific perspective on reality.Why the book is needed: many popular science books have been written, aimed at different levels of subject expertise, and nearly all treat their specific subject in isolation. Few attempt to link different sciences to their common foundations, and those that do are written by physicists. Since human knowledge is derived by, and relates to, the biological organism that human beings are, then such a book written from a biological perspective represents a novel perspective on the integration of science, and addresses new questions. This is such a book.Impressive aspects: the depth, breadth, consistency, and clarity of the work. (shrink)
