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 paper was motivated by what we see as an inconsistency between a 1988 paper by Brennan and Buchanan expressing concern that public choice might erode public confidence in government and previous work by Buchanan, in particular Buchanan. The one advantage we saw with the 1988 paper was that it, all by itself, is all one needs to dismiss MacLean’s depiction of Buchanan as an ideologically rigid extremist. We also found the same inconsistency occurring simultaneously in Buchanan’s writing in 1979. (...) Yet, based on Wagner, we conclude that such inconsistencies may reflect a strength in Buchanan’s scholarship. (shrink)

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.

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 considers prevailing environmental policy in the United States with the emphasis on liberty, markets, utilizing information, entrepreneurial discovery, and the economic analysis of political decisions. The general discussion is illustrated by the concern over global warming and policies for addressing this concern. The political incentives to confront environmental problems directly with mandates, restrictions, and subsidies ignore the power of liberty and market incentives to solve problems by fostering an impressive network of information transfer, increasing innovation, and expanding prosperity. (...) Indeed, most environmental policies systematically suppress liberty, censor the communication of information, and retard innovation and prosperity, with the result that they provide less environmental quality at greater cost than is possible. While such flawed policies might be justified in cases where pollution problems pose clear, serious, and immediate threats, we argue this is not true of global warming, and the most effective response to concerns over carbon emissions may be limiting the discretionary power of government to take direct action and rely on the indirect effects of liberty and market incentives to move us beyond the petroleum age more quickly and efficiently than will result from the direct action of government.

Economic models are founded in the idea of taking individuals' preferences as both known and given. This article explores the evolution of personal preferences, within a context of both entrepreneurial discovery and Objectivist philosophy. It begins by formalizing Ayn Rand's theory of Objectivism applied to human values, and continues by modeling preference changes similar to Schumpeter's theory of creative destruction—a process of self-discovery. Next the role of societal factors is examined in forming shared preference sets. Finally, the article describes how (...) the strength of human preferences is used to narrow choice sets in the presence of greater consumption options. (shrink)

Alternatives to convenience sampling (CS) are needed for HIV/STI surveillance of most-at-risk populations in Latin America. We compared CS, time space sampling (TSS), and respondent driven sampling (RDS) for recruitment of men who have sex with men (MSM) and transgender women (TW) in Lima, Peru. During concurrent 60-day periods from June-August, 2011, we recruited MSM/TW for epidemiologic surveillance using CS, TSS, and RDS. A total of 748 participants were recruited through CS, 233 through TSS, and 127 through RDS. The TSS (...) sample included the largest proportion of TW (30.7 %) and the lowest percentage of subjects who had previously participated in HIV/STI research (14.9 %). The prevalence of newly diagnosed HIV infection, according to participants' self-reported previous HIV diagnosis, was highest among TSS recruits (17.9 %) compared with RDS (12.6 %) and CS (10.2 %). TSS identified diverse populations of MSM/TW with higher prevalences of HIV/STIs not accessed by other methods. (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 volume represents the majority of papers delivered at the 1966 Workshop of Christian Philosophy and Religious Renewal held at the Catholic University of America. The Workshop's main task was to re-evaluate Christian philosophy in the light of contemporary phenomenological and analytic philosophy. Dietrich von Hildebrand's paper on the "Phenomenology of Values in a Christian Philosophy" urges a "rehabilitation" of ethics through an existential "value response." Ethical values are rescued from the "laboratory" of abstract study and returned to the world (...) where they belong. In "Analytic Philosophy and Language about God," W. Norris Clarke cites four basic challenges that analytic philosophy offers a philosophy of God: that theism has not unravelled the confusion concerning the use of "God" as naming or describing; that it is a "category mistake" to state "God is a necessary Being" since "necessary" is a term meaningful only in propositions and not about things; that according to the falsification theory of meaning there is no way to check the validity of statements about God, such as "God is providential and loving," since anything that happens would be providential and loving in a strange and hidden way; that there can be no meaningful predication of God since language would then refer to a realm that transcends experience. Father Clarke sees these challenges as forcing a re-evaluation of a philosophy of God and holds that only by using all the philosophical resources at hand, e.g., phenomenological, semantic, symbolic, metaphysical, will one be able to work out real positive meaning concerning God. Some other themes discussed are "Person," "Freedom," and "Love," written by Mother Mary Clark, L. B. Geiger, and Robert O. Johann respectively.—J. J. R. (shrink)

Hypnagogic and hypnopompic experiences (HHEs) accompanying sleep paralysis (SP) are often cited as sources of accounts of supernatural nocturnal assaults and paranormal experiences. Descriptions of such experiences are remarkably consistent across time and cultures and consistent also with known mechanisms of REM states. A three-factor structural model of HHEs based on their relations both to cultural narratives and REM neurophysiology is developed and tested with several large samples. One factor, labeled Intruder, consisting of sensed presence, fear, and auditory and visual (...) hallucinations, is conjectured to originate in a hypervigilant state initiated in the midbrain. Another factor, Incubus, comprising pressure on the chest, breathing difficulties, and pain, is attributed to effects of hyperpolarization of motoneurons on perceptions of respiration. These two factors have in common an implied alien ''other'' consistent with occult narratives identified in numerous contemporary and historical cultures. A third factor, labeled Unusual Bodily Experiences, consisting of floating/flying sensations, out-of-body experiences, and feelings of bliss, is related to physically impossible experiences generated by conflicts of endogenous and exogenous activation related to body position, orientation, and movement. Implications of this last factor for understanding of orientational primacy in self-consciousness are considered. Central features of the model developed here are consistent with recent work on hallucinations associated with hypnosis and schizophrenia. (shrink)

The present study examined the neural substrate of two classes of quantifiers: numerical quantifiers like ” at least three” which require magnitude processing, and logical quantifiers like ” some” which can be understood using a simple form of perceptual logic. We assessed these distinct classes of quantifiers with converging observations from two sources: functional imaging data from healthy adults, and behavioral and structural data from patients with corticobasal degeneration who have acalculia. Our findings are consistent with the claim that numerical (...) quantifier comprehension depends on a lateral parietal-dorsolateral prefrontal network, but logical quantifier comprehension depends instead on a rostral medial prefrontal-posterior cingulate network. These observations emphasize the important contribution of abstract number knowledge to the meaning of numerical quantifiers in semantic memory and the potential role of a logic-based evaluation in the service of non-numerical quantifiers.

Background Informed consent is an integral component of good medical practice. Many researchers have investigated measures to improve the quality of informed consent, but it is not clear which techniques work best and why. To address this problem, we propose developing a core outcome set to evaluate interventions designed to improve the consent process for surgery in adult patients with capacity. Part of this process involves reviewing existing research that has reported what is important to patients and doctors in the (...) informed consent process. Methods This qualitative synthesis comprises four phases: identification of published papers and determining their relevance; appraisal of the quality of the papers; identification and summary of the key findings from each paper while determining the definitiveness of each finding against the primary data; comparison of key themes between papers such that findings are linked across studies. Results Searches of bibliographic databases returned 11,073 titles. Of these, 16 studies met the inclusion criteria. Studies were published between 1996 and 2016 and included a total of 367 patients and 74 health care providers. Thirteen studies collected data using in-depth interviews and constant comparison was the most common means of qualitative analysis. A total of 94 findings were extracted from the primary papers and divided into 17 categories and ultimately 6 synthesised findings related to: patient characteristics, knowledge, communication, the model patient, trust and decision making. Conclusions This qualitative meta-aggregation is the first to examine the issue of informed consent for surgery. It has revealed several outcomes deemed important to capture by patients and clinicians when evaluating the quality of a consent process. Some of these outcomes have not been examined previously in research comparing methods for informed consent. This review is an important step in the development of a COS to evaluate interventions designed to improve the consent process for surgery. Registration The study protocol was registered on the international prospective register for systematic reviews. (shrink)

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)

Although living conditions have improved throughout history, protest, at least in the last few decades, seems to have increased to the point of becoming a normal phenomenon in modern societies. Contributors to this volume examine how and why this is the case and argue that although problems such as poverty, hunger, and violations of democratic rights may have been reduced in advanced Western societies, a variety of other problems and opportunities have emerged and multiplied the reasons and possibilities for protest.

This essay, which is the editor's introduction to part 1 of a multipart symposium on quietism, also constitutes his call for symposium papers. The symposium is meant be comprehensive. It is described as political and broadly cultural as well as religious, and in religious terms is said to cover not only the Catholic and Protestant quietisms (most properly so called) of the late seventeenth and eighteenth centuries, but also the proto-quietisms of the medieval Western church and reputedly quietist aspects of (...) the Gnostic, Eastern Orthodox, early Hasidic, Shi'ite, Jain and other Indic, Taoist, and Zen religious traditions. This introduction emphasizes the secular approaches, mostly antipolitical or postphilosophical, that wear the adjective “quietist” metaphorically, including the postmodern currents that Martha Nussbaum has named “hip quietism” and the “minimalist” philosophical version developed by Wittgenstein and some of his successors, notably Richard Rorty. This introduction concludes with attention to Rorty's late essay “Naturalism and Quietism,” then with a dedication of the entire symposium to Rorty's memory. (shrink)

BackgroundThe ARRIVE (Animal Research: Reporting of In Vivo Experiments) guidelines are widely endorsed but compliance is limited. We sought to determine whether journal-requested completion of an ARRIVE checklist improves full compliance with the guidelines.MethodsIn a randomised controlled trial, manuscripts reporting in vivo animal research submitted to PLOS ONE (March–June 2015) were randomly allocated to either requested completion of an ARRIVE checklist or current standard practice. Authors, academic editors, and peer reviewers were blinded to group allocation. Trained reviewers performed outcome adjudication (...) in duplicate by assessing manuscripts against an operationalised version of the ARRIVE guidelines that consists 108 items. Our primary outcome was the between-group differences in the proportion of manuscripts meeting all ARRIVE guideline checklist subitems.ResultsWe randomised 1689 manuscripts (control: n = 844, intervention: n = 845), of which 1269 were sent for peer review and 762 (control: n = 340; intervention: n = 332) accepted for publication. No manuscript in either group achieved full compliance with the ARRIVE checklist. Details of animal husbandry (ARRIVE subitem 9b) was the only subitem to show improvements in reporting, with the proportion of compliant manuscripts rising from 52.1 to 74.1% (X2 = 34.0, df = 1, p = 2.1 × 10−7) in the control and intervention groups, respectively.ConclusionsThese results suggest that altering the editorial process to include requests for a completed ARRIVE checklist is not enough to improve compliance with the ARRIVE guidelines. Other approaches, such as more stringent editorial policies or a targeted approach on key quality items, may promote improvements in reporting. (shrink)

High-spin states in the odd-odd N = Z nucleus Co-54 have been investigated by the fusion-evaporation reaction Si-28(S-32,1 alpha 1p1n)Co-54. Gamma-ray information gathered with the Ge detector array Gammasphere was correlated with evaporated particles detected in the charged particle detector system Microball and a 1 pi neutron detector array. A significantly extended excitation scheme of Co-54 is presented, which includes a candidate for the isospin T = 1, 6(+) state of the 1f(7/2)(-2) multiplet. The results are compared to large-scale shell-model (...) calculations in the fp shell. Effective interactions with and without isospin-breaking terms have been used to probe isospin symmetry and isospin mixing. A quest for deformed high-spin rotational cascades proved negative. This feature is discussed by means of cranking calculations. (shrink)

Two rotational bands have been identified and characterized in the proton-magic N = Z + 1 nucleus Ni-57. These bands complete the systematics of well-and superdeformed rotational bands in the light nickel isotopes starting from doubly magic Ni-56 to Ni-60. High-spin states in Ni-57 have been produced in the fusion-evaporation reaction Si-28(S-32, 2p1n)Ni-57 and studied with the gamma-ray detection array GAMMASPHERE operated in conjunction with detectors for evaporated light charged particles and neutrons. The features of the rotational bands in Ni-57 (...) are compared to those of neighbouring isotopes and interpreted by means of configuration-dependent cranked Nilsson-Strutinsky calculations. The two observed high-spin bands are considered signature partners and assigned to configurations with one 1g(9/2) proton and one 1g(9/2) neutron, resulting in an unambiguous understanding of the energetically favoured signature alpha = -1/2 band but a somewhat less satisfactory description of the signature alpha = +1/2 band.

The aim of this book is to explore some of the relations between morality and politics. Areas in which these are explored include the role of ideals in foreign policy , committing evil for the sake of a greater good in wartime, and lying and deception in political affairs. Illustrative examples are used throughout and include the Iraq war and its political fallout , Allied and Axis actions during the Second World War, decisions made by former Australian Prime Minister John (...) Howard and thought-experiments such as whether to lie about the Jewish family hiding in the basement when the Nazis come knocking at the door.Chapters 1 and 2, making up the first half of the book, are the highlight of it. In them, Coady confronts the realist critique of morality in foreign …. (shrink)

In “Hegel’s Phenomenological Method,” Kenley R. Dove maintains that the method of the Phenomenology of Spirit is not dialectical but instead wholly phenomenological. That is, Dove claims that Hegel’s method is purely descriptive. Dove’s interpretation has been highly influential and widely accepted. This article argues that, although there is a phenomenological aspect to Hegel’s method, that aspect itself presupposes a prior dialectical moment. Failure to account for that dialectical moment results in spirit being reduced to substance.
