As a natural example of a 1-random real, Chaitin proposed the halting probability Ω of a universal prefix-free machine. We can relativize this example by considering a universal prefix-free oracle machine U. Let [Formula: see text] be the halting probability of UA; this gives a natural uniform way of producing an A-random real for every A ∈ 2ω. It is this operator which is our primary object of study. We can draw an analogy between the jump operator from computability theory (...) and this Omega operator. But unlike the jump, which is invariant under the choice of an effective enumeration of the partial computable functions, [Formula: see text] can be vastly different for different choices of U. Even for a fixed U, there are oracles A =* B such that [Formula: see text] and [Formula: see text] are 1-random relative to each other. We prove this and many other interesting properties of Omega operators. We investigate these operators from the perspective of analysis, computability theory, and of course, algorithmic randomness.

This book undertakes a multifaceted and integrated examination of biometric identification, including the current state of the technology, how it is being used, the key ethical issues, and the implications for law and regulation. The five chapters examine the main forms of contemporary biometrics–fingerprint recognition, facial recognition and DNA identification– as well the integration of biometric data with other forms of personal data, analyses key ethical concepts in play, including privacy, individual autonomy, collective responsibility, and joint ownership rights, and proposes (...) a raft of principles to guide the regulation of biometrics in liberal democracies. Biometric identification technology is developing rapidly and being implemented more widely, along with other forms of information technology. As products, services and communication moves online, digital identity and security is becoming more important. Biometric identification facilitates this transition. Citizens now use biometrics to access a smartphone or obtain a passport; law enforcement agencies use biometrics in association with CCTV to identify a terrorist in a crowd, or identify a suspect via their fingerprints or DNA; and companies use biometrics to identify their customers and employees. In some cases the use of biometrics is governed by law, in others the technology has developed and been implemented so quickly that, perhaps because it has been viewed as a valuable security enhancement, laws regulating its use have often not been updated to reflect new applications. However, the technology associated with biometrics raises significant ethical problems, including in relation to individual privacy, ownership of biometric data, dual use and, more generally, as is illustrated by the increasing use of biometrics in authoritarian states such as China, the potential for unregulated biometrics to undermine fundamental principles of liberal democracy. Resolving these ethical problems is a vital step towards more effective regulation. (shrink)

A real is called properly n-generic if it is n-generic but not n+1-generic. We show that every 1-generic real computes a properly 1-generic real. On the other hand, if m > n ≥ 2 then an m-generic real cannot compute a properly n-generic real.

Many research ethics guidelines now oblige researchers to offer research participants the results of research in which they participated. This practice is intended to uphold respect for persons and ensure that participants are not treated as mere means to an end. Yet some scholars have begun to question a generalised duty to disclose research results, highlighting the potential harms arising from disclosure and questioning the ethical justification for a duty to disclose, especially with respect to individual results. In support of (...) this view, we argue that current rationales for a duty of disclosure do not form an adequate basis for an ethical imperative. We review policy guidance and scholarly commentary regarding the duty to communicate the results of biomedical, epidemiological and genetic research to research participants and show that there is wide variation in opinion regarding what should be disclosed and under what circumstance. Moreover, we argue that there is fundamental confusion about the notion of “research results,” specifically regarding three core concepts: the distinction between aggregate and individual results, amongst different types of research, and across different degrees of result veracity. Even where policy guidance and scholarly commentary have been most forceful in support of an ethical imperative to disclose research results, ambiguity regarding what is to be disclosed confounds ethical action.

Advances in life-saving technologies in the past few decades have challenged our traditional understandings of death. Traditionally, death was understood to occur when a person stops breathing, their heart stops beating and they are cold to the touch. Today, physicians determine death by relying on a diagnosis of ‘total brain failure’ or by waiting a short while after circulation stops. Evidence has emerged, however, that the conceptual bases for these approaches to determining death are fundamentally flawed and depart substantially from (...) the established biological conception of death. We argue that the current approach to determining death consists of two different types of unacknowledged legal fictions. These legal fictions were developed for practices that are largely ethically legitimate but need to be reconciled with the law. The considerable debate over the determination of death in the medical and scientific literature has not informed the public that vital organs are being procured from still-living donors and it seems unlikely that this information can remain hidden for long. Given the instability of the status quo and the difficulty of making the substantial legal changes required by complete transparency, we argue for a second-best policy solution: acknowledging the legal fictions involved in determining death to move in the direction of greater transparency. This may someday result in more substantial legal change to directly confront the challenges raised by life-sustaining and life-preserving technologies without the need for fictions. (shrink)

Miller first examines the New Critics’ theory of metaphor, then presents his own views. There is one chapter on Hulme and Richards, one on Empson, Tate, Ransom and Brooks, and a third on Wimsatt, Wheelwright, and Krieger. Chapter Four contains Miller’s position and applies it to some metaphors from the metaphysical poets, and Chapter Five examines the problem of the objective status of a work of verbal art. Miller uses Richards’ distinction between the tenor and vehicle of (...) a metaphor; in "My love is a red, red rose," "love" is the tenor and "rose" the vehicle, and a metaphor occurs only in the tense convergence of tenor and vehicle. With this formal scheme he defines surface and submerged metaphors—the former having both elements stated, the latter having the tenor unstated but implied; Miller distinguishes these from moribund metaphors, like the "foot" of a mountain, in which the appropriate tenors are forgotten, not submerged. He distinguishes positive and negative metaphor, depending upon the emphasis the metaphor places on either the fusion or the resistance between tenor and vehicle, for both forces must operate within a lively metaphor. He distinguishes simple, complex and compound metaphors, to the extent that tenor and vehicle are either simple terms or else contain, each or both of them, metaphors inside themselves. In the case of compound metaphors, sometimes the vehicle can be submerged, and if the critic can find what the vehicle is, the poetic passage acquires a more condensed and unified logical form. Miller’s application of these schemes to concrete instances of metaphor are carried out to good effect. His treatment of the epistemology and ontology of a work of verbal art is less successful; he wishes to accommodate both subjective and objective aspects, but tends to consider a manifestation of a poem as the poem itself. He considers the written documentation of a poem to be marks on a surface which serve as stimuli to the reader’s awareness; but units of documentation are written words, not marks, and the process of reading is not, as he claims, a process of decoding. He distinguishes between oral documentation and performance, but seems to think records, tapes and films are instances of the former; would not memory, or perhaps even recitation by rote, be better examples of oral documentation? He considers Saussurian langue as an example of a "cultural object" which finds manifestation in parole; but if this is so, how can there ever be intermediate cultural objects like poems or stories? Langue would be the only verbal cultural object there is. It would be better to consider poems and stories as cultural objects, and language as a potential matrix for them, much as matter is a matrix for substances. Miller objects to the metaphor of "organism" for a poem, because, he says, when we take a poem apart in critical analysis, we do not kill it; therefore the metaphor of "machine" is better—something that can be taken apart and put together again. But surely the correction here is not to replace organism by machine, but to change one’s understanding of what it is to take apart. The critic takes apart in thought, the way a mathematician does, and not like a butcher. Miller’s book is extremely interesting, asks many good questions, and should be read with profit and delight by philosophers interested in language.—R. S. (shrink)

EveryK-trivial set is computable from an incomplete Martin-Löf random set, i.e., a Martin-Löf random set that does not compute the halting problem.

A vision of a living code of ethics is proposed to counter the emphasis on negative phenomena in the study of organizational ethics. The living code results from the harmonious interaction of authentic leadership, five key organizational processes (attraction–selection–attrition, socialization, reward systems, decision-making and organizational learning), and an ethical organizational culture (characterized by heightened levels of ethical awareness and a positive climate regarding ethics). The living code is the cognitive, affective, and behavioral manifestation of an ethical organizational identity. We draw (...) on business ethics literature, positive organizational scholarship, and management literature to outline the elements of positive ethical organizations as those exemplary organizations consistently practicing the highest levels of organizational ethics. In a positive ethical organization, the right thing to do is the only thing to do. (shrink)

Whole eye transplantation (WET) remains experimental. Long presumed impossible, recent scientific advances regarding WET suggest that it may become a clinical reality. However, the ethical implications of WET as an experimental therapeutic strategy remain largely unexplored. This article evaluates the ethical considerations surrounding WET as an emerging experimental treatment for vision loss. A thorough review of published literature pertaining to WET was performed; ethical issues were identified during review of the articles.

In lieu of an abstract, here is a brief excerpt of the content:Reviewed by:The Rhetoric of RHETORIC: The Quest for Effective CommunicationCarolyn R. MillerThe Rhetoric of RHETORIC: The Quest for Effective Communication. Wayne C. BoothMalden, Mass: Blackwell, 2004. Pp. xvi + 206. $20.95, paperback.By using the traditional word rhetoric I want to suggest a whole philosophy of how men succeed or fail in discovering together, in discourse, new levels of truth (or at least agreement) that neither side suspected before.—Wayne C. (...) Booth, 1974Listening-Rhetoric is what I most long to celebrate and practice—the kind that is sadly rare.... Here both sides join in a trusting dispute, determined to listen to the opponent's arguments, while persuading the opponent to listen in exchange.... Both sides are pursuing not just victory but a new reality, a new agreement about what is real.—Wayne C. Booth, 2004By the evidence of these two quotations, the late Wayne Booth sustained a passionate interest in a constructivist, cooperative rhetoric for at least thirty years. His 1974 Modern Dogma and the Rhetoric of Assent first sounds many of the themes that are rearticulated in his 2004 The Rhetoric of RHETORIC, a volume in the Blackwell Manifestos series. Both books were motivated by evident failures of public discourse, the earlier one by those emanating from the Vietnam War, including student protests at the University of Chicago, and the recent one by multiple rhetorical sins of the Bush administration and the national media, especially those concerning the war in Iraq. Indeed, Booth confesses here that his distress dates at least to 1963, when he lamented that "the debate about the [Kennedy] assassination [may be] a greater national disgrace than the assassination itself" (109).What animates Booth in both books is the conviction not that only we can do better in conducting our discursive relationships as a nation, as institutions, as families, but that we must do so. We must do so because our ability to live and progress together depends on our talking rather than resorting to force and on our talking in a way that engenders trust and enables continued debate, rather than provoking mistrust and disrespect. The two enemies he has always in sight are violence and deception. These are two forms of rhetorical failure, but the two become entangled when "violence and the threat of violence corrupt rhetoric," particularly during times of war (118), and when corrupt rhetoric itself becomes a kind of violence (48). [End Page 261]As a "manifesto" addressed to a non-specialist audience, The Rhetoric of RHETORIC is relatively brief, engagingly written, and passionately argued. It includes chapters on definitions of rhetoric (good and bad), the history of rhetorical studies, the difficulties of judging rhetoric (i.e., the disjunction between instrumental and ethical effectiveness), the dispersal of rhetoric to multiple disciplines and forums, the condition of rhetorical education today, the dangers of bad rhetoric in politics and in the media, and a demonstration of how our many intractable debates might be improved with "listening-rhetoric," using as a case example the "warfare" between science and religion. Throughout, Booth dramatizes his ideal of listening-rhetoric by engaging in frequent proleptic questioning and refutation as well as reflexive commentary.Anyone who heard Booth talk at a conference within the past decade or more has first-hand knowledge of his predilection for neologism, and he indulged himself in this book (though he resisted in 1974; see Modern Dogma, 11n5). His term for bad rhetoric, the rhetoric that exacerbates misunderstanding or seeks victory through deception, is "rhetrickery"; his term for the best rhetoric, a kind of critical consciousness that seeks to find common ground and to remove misunderstanding, is "rhetorology." We are also introduced to LR (listening-rhetoric), WR (win-rhetoric), BR (bargain-rhetoric), Rhet-Ed (rhetorical education), P-Rhet (political rhetoric), and MR (media rhetoric).Rhetorology, or listening-rhetoric, is Booth's solution to our rhetorical woes, a solution that admittedly has both philosophical and practical limitations. Rhetorology opposes rhetrickery and some versions of win-rhetoric. He is at some pains to explain and sequester these damaging capabilities so that the unsavory aspects of rhetoric's reputation do not obscure its positive potential.

In lieu of an abstract, here is a brief excerpt of the content:Philosophy and Rhetoric 34.2 (2001) 179-181 [Access article in PDF] Book Review Rethinking the Rhetorical Tradition: From Plato to Postmodernism Rethinking the Rhetorical Tradition: From Plato to Postmodernism. James L. Kastely. New Haven, CT: Yale University Press, 1997. Pp. viii + 293. $30.00. In Rethinking the Rhetorical Tradition, James Kastely presents an alternative to the "standard" rhetorical tradition; he calls this alternative skeptical rhetoric, describes its characteristic activity as (...) refutation, and claims for it special relevance in negotiating postmodern challenges to rhetoric, specifically, that it can serve as a "refutation of postmodernism" (23). This alternative tradition inheres in a canon of works somewhat different from the standard canon, and an examination of key works organizes most of the chapters in this book. To establish and articulate this tradition in the classical era, Kastely examines Plato's Gorgias and Meno, Sophocles' Philoctetes, and Euripides' Hecuba; he then moves to the modern era, and to two works that address themes central to ancient rhetorical skepticism: Jane Austen's Persuasion (1818) and Jean-Paul Sartre's What Is Literature? (1949). Finally, Kastely turns to the two prongs of the postmodern reappropriation of traditional rhetoric, the tropological formalism of Paul de Man and the ideological approaches of Marxist critics such as Terry Eagleton, challenging both of them with the comic skepticism of Kenneth Burke.The skeptical tradition begins with Socrates, of course. It takes as its central problem, not the impossibility or contingency of knowledge, but the existence of injustice. In a political community, the unavoidability of doing inadvertent injury both requires rhetoric and at the same time makes it party to continued injustice: "[D]oing injury is an inescapable aspect of a being who is born into a world that is shaped by a language and by conventional practices that embody a particular set of values" (42). It is these prior commitments and conventional practices that, Kastely argues, lead us to cause injury. Thus, the positive task of rhetoric is not to persuade others away from injustice or to promote remedies; it is to keep us constantly open to refutation, to the possibility of seeing an alternative to the inadvertent wrong we commit. The inherency of injustice is what makes rhetoric a philosophical problem, but refutation is what rhetoric can offer to philosophy (a claim that might surprise philosophers). And in his reading of the Meno, Kastely argues explicitly for a rhetorical, rather than philosophical or logical, understanding of refutation.Overall, Kastely offers us a Plato who is not the enemy of rhetoric, but rather "the most sophisticated and profound rhetorical theorist" (30), who dramatizes in dialogue the philosophical dilemma of rhetoric. In [End Page 179] Sophocles and Euripides, he finds dramatists who illustrate practical forms the dilemma can take, specifically the problem of the unavailable audience. In the Philoctetes, the problem is how to regain the trust and confidence of the marginalized and disenfranchised, how to restore the status of rhetorical audience to one who no longer believes that justice is possible. In the Hecuba, the problem is how a disempowered rhetor can speak to the powerful. In both plays, but especially in Hecuba, the proximity of rhetoric to violence is a practical consequence of the unsolved philosophical problem.Kastely admits that the skeptical legacy from classical rhetoric has had little effect since antiquity. His argument that this alternate tradition deserves recognition is made primarily by his chapters on Austen and Sartre. He sees the works he examines here as raising a question central to rhetorical skepticism: "Can there be a way of speaking and writing that can effectively challenge the marginalization and dehumanization of people in a world in which traditional structures of authority that made discourse coherent have vanished or, at least, are seriously and irretrievably eroded?" (139-40). Both question Enlightenment assumptions about universality and at the same time confront the vacuum left by the erosion of local communal and authority structures. Austen's "active exploration" of a "crisis in discursive practice" (141) and Sartre's concern with the "social responsibility of the writer" and the loss of a public... (shrink)

This paper is a critical analysis of David Rayfield's attempt to distinguish true from correct descriptions of human actions (Inquiry, Vol. 13 [1970], Nos. 1?2). It is argued that the analysis fails to do the job required of it for two reasons. First, the analysis of true descriptions is circular insofar as it turns on the notion of an ?unbound action?. Secondly, and independent of the charge of circularity, it is shown that the basis upon which Rayfield draws the true?correct (...) distinction leads to certain unacceptable consequences for action theory.

Late in 1990, the Center for the Study of Ethics in the Professions at Illinois Institute of Technology (lIT) received a grant of more than $200,000 from the National Science Foundation to try a campus-wide approach to integrating professional ethics into its technical curriculum.! Enough has now been accomplished to draw some tentative conclusions. I am the grant's principal investigator. In this paper, I shall describe what we at lIT did, what we learned, and what others, especially philosophers, can learn (...) from us. We set out to develop an approach that others could profitably adopt. I believe that we succeeded. (shrink)

This report describes the rationale, approaches, organization, and resource development leading to a large-scale deletion bin map of the hexaploid wheat genome. Accompanying reports in this issue detail results from chromosome bin-mapping of expressed sequence tags representing genes onto the seven homoeologous chromosome groups and a global analysis of the entire mapped wheat EST data set. Among the resources developed were the first extensive public wheat EST collection. Described are protocols for sequencing, sequence processing, EST nomenclature, and the assembly of (...) ESTs into contigs. These contigs plus singletons were used for selection of distinct sequence motif unigenes. Selected ESTs were rearrayed, validated by 5′ and 3′ sequencing, and amplified for probing a series of wheat aneuploid and deletion stocks. Images and data for all Southern hybridizations were deposited in databases and were used by the coordinators for each of the seven homoeologous chromosome groups to validate the mapping results. Results from this project have established the foundation for future developments in wheat genomics. (shrink)

The corporate social responsibility literature recognizes that firms’ existing CSR reputation can serve as a safeguard from the impact of reputation-damaging events on a firm’s social legitimacy. However, the literature has yet to focus on the extent to which CSR activities can help mitigate such damage, post-event. This article examines how a firm’s social actions following a product recall facilitate the recovery of its diminished social legitimacy. We test our predictions using a sample of 197 product recalls involving 168 publicly (...) traded corporations from 1999 to 2009 and demonstrate that the speed of the CSR response, the frequency of CSR activities, and the intensity of CSR activities have a significant effect on firm recovery following crisis. The effects were most pronounced in instances where the magnitude of the recall was most severe. The visibility of the recall has a limited impact on post-event recovery. We discuss our contributions to research on strategic CSR and recovery. (shrink)

Purpose Prescription stimulant use as “cognitive enhancers” has been described among undergraduate college students. However, the use of prescription stimulants among future health care professionals is not well characterized. This study was designed to determine the prevalence of prescription stimulant misuse among students at an academic health sciences center. -/- Method Electronic surveys were e-mailed to 621 medical, pharmacy, and respiratory therapy students at East Tennessee State University for four consecutive weeks in fall 2011. Completing the survey was voluntary and (...) anonymous. Surveys asked about reasons for, frequency of, and side effects of nonprescription misuse of prescription stimulants. Given the sensitive material, an opportunity to win one of ten $50 gift cards was used as an incentive. -/- Results Three hundred seventy-two (59.9%) students completed the survey from three disciplines (47.6% medical, 70.5% pharmacy, and 57.6% respiratory therapy). Overall, 11.3% of responders admitted to misusing prescription stimulants. There was more misuse by respiratory therapy students, although this was not statistically significant (10.9% medicine, 9.7% pharmacy, 26.3% respiratory therapy; P = .087). Reasons for prescription stimulant misuse included to enhance alertness/ energy (65.9%), to improve academic performance (56.7%), to experiment (18.2%), and to use recreationally/get high (4.5%). -/- Conclusions Prescription stimulant misuse was prevalent among participating students, but further research is needed to describe prevalence among future health care workers more generally. The implications and consequences of such misuse require further study across professions with emphasis on investigating issues of academic dishonesty (e.g., “cognitive enhancement”), educational quality, and patient safety or health care quality.

This paper presents a preliminary analysis of the first participatory budgeting experiment in the United States, in Chicago's 49th Ward. There are two avenues of inquiry: First, does participatory budgeting result in different budgetary priorities than standard practices? Second, do projects meet normative social justice outcomes? It is clear that allowing citizens to determine municipal budget projects results in very different outcomes than standard procedures. Importantly, citizens in the 49th Ward consistently choose projects that the research literature classifies as low (...) priority. The results are mixed, however, when it comes to social justice outcomes. While there is no clear pattern in which projects are located only in affluent sections of the ward, there is evidence of geographic clustering. Select areas are awarded projects like community gardens, dog parks, and playgrounds, while others are limited to street resurfacing, sidewalk repairs, bike racks, and bike lanes. Based on our findings, we offer suggestions for future programmatic changes. (shrink)

Many countries have regulations that require firms to engage in minimum levels of corporate social activities in areas such as the environment and social welfare. In this paper, we argue that changes in a firm’s compliance with CS regulations are reflected in its reputation for corporate social responsibility, which affects the firm’s performance. The performance impacts depend on whether the firm’s CSR reputation in the current and prior periods is positive, neutral, or negative. Our theoretical framework draws on the reputation (...) literature and on the concepts of recency bias, which weights the present more heavily than the past, and negativity bias, which weights negative assessments more heavily than neutral or positive assessments. We test our hypotheses on a sample of 7317 banks over 1992–2007 where we compare a bank’s return on assets with its current and prior compliance ratings under the U.S. Community Reinvestment Act. We find that changes in CSR reputation have predictable, asymmetric, and sizeable impacts on firm performance. For example, for an average bank with $1 billion in assets, gaining a positive CSR reputation translates into a rise in profits of 4.04%; gaining a negative CSR reputation results in a drop in profits of − 7.8%.
