Many theories of explanation evaluation are based on context‐independent criteria. Such theories either restrict their consideration to explanation towards a fixed goal, or assume that all valid explanations are equivalent, so that evaluation criteria can be neutral to the goals underlying the attempt to explain. However, explanation can serve a range of purposes that place widely divergent requirements on the information an explanation must provide. It is argued that understanding what determines explanations' goodness requires a dynamic theory of evaluation, based (...) on analysis of the information needed to satisfy the many goals that can prompt explanation; this view conforms to the commonsense idea that people accept and apply explanations precisely if those explanations give the information they need. A range of goals that can underly explanation is examined, and a theory is presented for evaluating whether an explanation provides the information an explainer needs for these goals. The theory is illustrated by sketching its implementation in the computer program, ACCEPTER, which does goal‐based evaluation of the goodness of explanations for surprising events in news stories.

In The Media and Modernity, Thompson develops an interactional theory of communication media that distinguishes between three basic types of interaction: face-to-face interaction, mediated interaction, and mediated quasi-interaction. In the light of the digital revolution and the growth of the internet, this paper introduces a fourth type: mediated online interaction. Drawing on Goffman’s distinction between front regions and back regions, Thompson shows how mediated quasi-interaction and mediated online interaction create new opportunities for the leakage of information and symbolic content from (...) back regions into front regions, with consequences that can be embarrassing, damaging and, on occasion, hugely disruptive. The growing role of mediated quasi-interaction and mediated online interaction has reconstituted the political field so that political life now unfolds in an information environment that is much more difficult to control, creating a permanently unstable arena in which leaks, revelations and disclosures are always capable of disrupting the most well-laid plans.

In lieu of an abstract, here is a brief excerpt of the content:Future Directions for Human Cloning by Embryo Splitting:After the HullabalooCynthia B. Cohen (bio)In October 1993, a paper entitled, "Experimental Cloning of Human Polyploid Embryos Using an Artificial Zona Pellucida," was presented at a joint meeting of the American Fertility Society and the Canadian Fertility and Andrology Society. Although it was awarded a prize, its authors, who are affiliated with George Washington University, decided against calling a press conference to (...) announce their findings. Word of their experiment soon leaked out, however, and the New York Times blazoned on its front page that human embryo cloning had been achieved. The story was accompanied by a diagram of cloning by nuclear transplantation.Newspapers and television networks around the world picked up the story and embellished it. The idea of unlimited, xeroxed copies of human beings gripped the public imagination. Wild scenarios of hundreds of Hitlers plotting to take over the world and of clones giving birth to their own twins enlivened media reports. Only gradually did it become clear that the term "polyploid" in the title of the paper referred to abnormal embryos that could never develop into living human beings and that "cloning" referred to embryo splitting or twinning, not to nuclear transplantation or the transfer of a donor nucleus into an enucleated egg. Once this sank into public consciousness, the "hullabaloo," as Dr. Howard W Jones, Jr., called it, died down.It left in its wake unanswered questions about the ethics of splitting embryos. During the height of the publicity given to the George Washington experiment, newspaper and TV stories had not delved in any depth into the ethical issues it raised. Ethicists, given limited time to discuss the ethical questions at stake, had been quoted in quick, simplistic responses. Some had offered little analysis of the rights and wrongs of embryo splitting, but, revealing tremendous creative talent, had spun out [End Page 187] imaginary and frightening applications of the procedure. This was a story essentially about ethics in which ethics was never really discussed.The National Advisory Board on Ethics in Reproduction* (NABER), an independent, multidisciplinary group that addresses ethical issues in modern reproductive science, technology, and care, became concerned about the sparsity of reflective ethical debate about embryo splitting. NABER's chair, Albert Jonsen, observed that "reporters phoning ethicists for comment and ethicists appearing on talk shows do not a debate make. Debate requires face to face (or at least essay to essay) argument among persons sharing the same information. This has yet to take place." Consequently, NABER decided to convene a workshop on human cloning by embryo splitting at the National Academy of Sciences in February 1994. The board invited participants who would provide a broad range of opinion about the ethical and public policy issues entailed by human embryo splitting. Embryologists, ethicists, reproductive biologists, public policy experts, staff from the National Institutes of Health (NIH), legal scholars, journalists, and infertility specialists were among those who participated. The feature articles in this issue of the Kennedy Institute of Ethics Journal derive from that workshop. Their authors were given free rein to take whatever stance they deemed ethically supportable.The first article is designed to provide some understanding of the science of human cloning as a basis for exploring the ethical issues raised by this set of techniques. Jacques Cohen, a leading reproductive embryologist, and Giles Tomkin, a science writer, both of Cornell University Medical School, explain, in a way that is clear to laypersons and biologists alike, the meaning, nature, and function of cloning. They discuss recent: advances in this area and offer an assessment of feasible uses of human cloning procedures, hoping to dispel what they view as mistaken fears about its future applications. Dr. Howard W Jones, Jr., a pioneer infertility specialist, briefly comments on Cohen and Tomkin's paper, pointing out that embryo splitting may not improve pregnancy results if genetic heterogeneity is required for successful embryo transfer and implantation.In the next article, three major ethical arguments against human cloning by embryo splitting are analyzed and rejected by Ruth Macklin, an expert in reproductive ethics from Albert Einstein College of Medicine. She finds the first argument, that the worth of individuals... (shrink)

Popular interest in the progress of physical science has increased very rapidly in the last few years. Perhaps the spectacular ‘mysteries’ of wireless and the intriguing paradoxes of the theory of relativity are the chief causes. For every home now has its Magic Box—a piece of pure physics; there is not a familiar thing in it, not even that sine qua non of all things that ‘work’—a wheel, only mysterious parts called condensers, grid-leaks, inductances, and thermionic valves. And surely, when (...) a Sunday newspaper produces a facsimile page of Einstein’s recent paper in German containing abstruse tensor equations, reverence for the mathematical physicist is nearing its zenith.

Background Residual dried blood spots (rDBS) from newborn screening programmes represent a valuable resource for medical research, from basic sciences, through clinical to public health. In Hong Kong, there is no legislation for biobanking. Parents’ view on the retention and use of residual newborn blood samples could be cultural-specific and is important to consider for biobanking of rDBS. Objective To study the views and concerns on long-term storage and secondary use of rDBS from newborn screening programmes among Hong Kong Chinese (...) parents. Methods A mixed-method approach was used to study the views and concerns on long-term storage and secondary use of rDBS from newborn screening programmes among Hong Kong Chinese parents of children 0–3 years or expecting parents through focus groups (8 groups; 33 participants) and a survey (n = 1012, 85% mothers) designed with insights obtained from the focus groups. We used framework analysis to summarise the themes as supportive factors, concerns and critical arguments for retention and secondary use of rDBS from focus group discussion. We used multiple logistic regression to assess factors associated with support for retention and secondary use of rDBS in the survey. Results Both in focus groups and survey, majority of parents were not aware of the potential secondary use of rDBS. Overall secondary use of rDBS in medical research was well accepted by a large proportion of Hong Kong parents, even if all potential future research could not be specified in a broad consent. However parents were concerned about potential risks of biobanking rDBS including leaking of data and mis-use of genetic information. Parents wanted to be asked for permission before rDBS are stored and mainly did not accept an “opt-out” approach. The survey showed that parents born in mainland China, compared to Hong Kong born parents, had lower awareness of newborn screening but higher support in biobanking rDBS. Higher education was associated with support in rDBS biobanking only among fathers. Conclusion Long-term storage and secondary use of rDBS from newborn screening for biomedical research and a broad consent for biobanking of rDBS are generally acceptable to Hong Kong parents given their autonomy is respected and their privacy is protected, highlighting the importance of an accountable governance and a transparent access policy for rDBS biobanks.

The increasing use of digital technologies in judicial and arbitration proceedings increases the usage of digital evidence by the parties, which brings the necessity of creating patterns for adjudicators to admit and assess this new type of evidence. This paper generally addresses digital evidence focusing on the second moment in international arbitration proceedings. It also narrows the topic to hacked and leaked evidence and its admissibility in international arbitration. The literature review showed a significant amount of research devoted to the (...) evidence in arbitration. Some considered electronic evidence within one jurisdiction; others focused on certain forms of digital evidence such as electronic signatures. Papers on digital evidence in international arbitration approach arbitration rules for digital evidence but skip admissibility issues. No systemic and complex works research digital evidence in arbitration, explicitly focusing on the admissibility of hacked and leaked digital evidence from a comparative perspective. Also, no research deals with enforcing international arbitration awards relying on illegally obtained digital evidence. In these cases, there could be a possible violation of domestic public policy under the New York Convention terms (art. V, 2, b). That is why the paper aims to offer the concept of digital evidence in international arbitration, including hacked and leaked evidence, criteria of its admissibility and relevance, and design the arbitration guidelines for assessing hacked and leaked evidence. Comparative legal analysis of the international arbitration rules and national procedure law allowed us to compare the regulatory approaches to the definition of digital evidence and its admissibility worldwide. The method of legal modeling allowed designing model guidelines for arbitral tribunals to evaluate the admissibility and relevance of digital evidence, including hacked and leaked evidence. Moreover, the case study method allowed us to analyze jurisprudence and define criteria for admission of hacked and leaked evidence. We conclude that the admissibility of hacked and leaked evidence depends solely on the arbitrator’s broad discretion to assess the evidence. Nevertheless, thorough evidence analysis and a well-reasoned award are always mandatory. (shrink)

First published in 1986, Knowledge, Belief, and Witchcraft remains the only analysis of indigenous discourse about an African belief system undertaken from within the framework of Anglo-American analytical philosophy. Taking as its point of departure W. V. O. Quine's thesis about the indeterminacy of translation, the book investigates questions of Yoruba epistemology and of how knowledge is conceived in an oral culture.

The New Evil Demon problem has been hotly debated since the case was introduced in the early 1980’s (e.g. Lehrer and Cohen 1983; Cohen 1984), and there seems to be recent increased interest in the topic. In a forthcoming collection of papers on the New Evil Demon problem (Dutant and Dorsch, forthcoming), at least two of the papers, both by prominent epistemologists, attempt to resist the problem by appealing to the distinction between justification and excuses. My primary aim here is (...) to critically evaluate this new excuse maneuver as a response to the New Evil Demon problem. -/- Their response attempts to give us reason to reject the idea that victims of the New Evil Demon have justification for believing as they do. I shall argue that this approach is ultimately unsuccessful, however much of value can be learned from these attempts. In particular, progress in the debate can be made by following those who advance the excuse maneuver and make explicit the connection between epistemic justification and epistemic norms. By doing so, the questions being debated are clarified, as is the methodology being used to attempt to answer them. (shrink)

There are various equivalent formulations of the Church-Turing thesis. A common one is that every effective computation can be carried out by a Turing machine. The Church-Turing thesis is often misunderstood, particularly in recent writing in the philosophy of mind.

It is common to account for our senses on the basis of our sensory organs. One way of glossing why Aristotle famously counted five senses—and why his count became common sense in the West and elsewhere—is because there are five rather obvious organs of sense. In more modern accounts, this organ criterion of the senses has transformed into a neurobiological criterion; that is to say, part of what it means to be a sense is to have an associated organ with (...) appropriate physiological properties. For example, part of the claim that humans have a sense of vision is that we have a non-vestigial organ (the eye) that has cells (photoreceptors) especially sensitive to the properties of electromagnetic radiation. However, the nature of this “organ criterion” is a point of some contention. Is it a sufficient criterion? Necessary? To be called “vision” need the organ mediating it give rise to “visual experiences”? This chapter will consider the neurobiological criterion as it was originally presented in Aristotle and later reconceptualized in 19th-century neurophysiologist Johannes Müller’s “Law of Specific Nerve Energies.” By understanding the role of neurobiology in these accounts, we will be able to explore the deficiencies of contemporary accounts that downplay neurobiology in differentiating the senses. We will consider one of these accounts in detail: Alva Noë’s recent arguments in favor of an enactive approach to perceptual psychology. (shrink)

For German townsmen, life during the sixteenth and seventeenth centuries was characterized by a culture of arms, with urban citizenry representing the armed power of the state. This book investigates how men were socialized to the martial ethic from all sides, and how masculine identity was confirmed with blades and guns.
