α-recursion lifts classical recursion theory from the first transfinite ordinal ω to an arbitrary admissible ordinal α [10]. Idealized computational models for α-recursion analogous to Turing machine models for classical recursion have been proposed and studied [4] and [5] and are applicable in computational approaches to the foundations of logic and mathematics [8]. They also provide a natural setting for modeling extensions of the algorithmic logic described in [1] and [2]. On such models, an α-Turing machine can complete a θ-step (...) computation for any ordinal θ < α. Here we consider constraints on the physical realization of α-Turing machines that arise from the structure of physical spacetime. In particular, we show that an α-Turing machine is realizable in a spacetime constructed from R only if α is countable. While there are spacetimes where uncountable computations are possible and while they may even be empirically distinguishable from a standard spacetime, there is good reason to suppose that such nonstandard spacetimes are nonphysical. We conclude with a suggestion for a revision of Church’s thesis appropriate as an upper bound for physical computation. (shrink)

There are theoretical limitations to what can be implemented by a computer program. In this paper we are concerned with a limitation on the strength of computer implemented deduction. We use a version of the Curry paradox to arrive at this limitation.

In this note, we consider constraints on the physical possibility of transfinite Turing machines that arise from how one models the continuous structure of space and time in one's best physical theories. We conclude by suggesting a version of Church's thesis appropriate as an upper bound for physical computation given how space and time are modeled on our current physical theories.

There is significant interest in type-free systems that allow flexible self-application. Such systems are of interest in property theory, natural language semantics, the theory of truth, theoretical computer science, the theory of classes, and category theory. While there are a variety of proposed type-free systems, there is a particularly natural type-free system that we believe is prototypical: the logic of recursive algorithms. Algorithmic logic is the study of basic statements concerning algorithms and the algorithmic rules of inference between such statements. (...) As shown in [1], the threat of paradoxes, such as the Curry paradox, requires care in implementing rules of inference in this context. As in any type-free logic, some traditional rules will fail. The first part of the paper develops a rich collection of inference rules that do not lead to paradox. The second part identifies traditional rules of logic that are paradoxical in algorithmic logic, and so should be viewed with suspicion in type-free logic generally. (shrink)

We develop a functional abstraction principle for the type-free algorithmic logic introduced in our earlier work. Our approach is based on the standard combinators but is supplemented by the novel use of evaluation trees. Then we show that the abstraction principle leads to a Curry fixed point, a statement C that asserts C ⇒ A where A is any given statement. When A is false, such a C yields a paradoxical situation. As discussed in our earlier work, this situation leaves (...) one no choice but to restrict the use of a certain class of implicational rules including modus ponens. (shrink)

In Taking the Path of Zen , Robert Aitken provided a concise guide to zazen (Zen meditation) and other aspects of the practice of Zen. In The Mind of Clover he addresses the world beyond the zazen cushions, illuminating issues of appropriate personal and social action through an exploration of the philosophical complexities of Zen ethics. Aitken's approach is clear and sure as he shows how our minds can be as nurturing as clover, which enriches the soil and (...) benefits the environment as it grows. The opening chapters discuss the Ten Grave Precepts of Zen, which, Aitken points out, are "not commandments etched in stone but expressions of inspiration written in something more fluid than water." Aitken approaches these precepts, the core of Zen ethics, from several perspectives, offering many layers of interpretation. Like ripples in a pond, the circles of his interpretation increasingly widen, and he expands his focus to confront corporate theft and oppression, the role of women in Zen and society, abortion, nuclear war, pollution of the environment, and other concerns. The Mind of Clover champions the cause of personal responsibility in modern society, encouraging nonviolent activism based on clear convictions. It is a guide that engages, that invites us to realize our own potential for confident and responsible action. (shrink)

Sensory processing dysfunction is characterized by a behaviorally observed difference in the response to sensory information from the environment. While the cerebellum is involved in normal sensory processing, it has not yet been examined in SPD. Diffusion tensor imaging scans of children with SPD and typically developing controls were compared for fractional anisotropy, mean diffusivity, radial diffusivity, and axial diffusivity across the following cerebellar tracts: the middle cerebellar peduncles, superior cerebellar peduncles, and cerebral peduncles. Compared to TDC, children with SPD (...) show reduced microstructural integrity of the SCP and MCP, characterized by reduced FA and increased MD and RD, which correlates with abnormal auditory behavior, multisensory integration, and attention, but not tactile behavior or direct measures of auditory discrimination. In contradistinction, decreased CP microstructural integrity in SPD correlates with abnormal tactile and auditory behavior and direct measures of auditory discrimination, but not multisensory integration or attention. Hence, altered cerebellar white matter organization is associated with complex sensory behavior and attention in SPD, which prompts further consideration of diagnostic measures and treatments to better serve affected individuals.

This handbook offers a deep analysis of the main forms of legal reasoning and argumentation from both a logical-philosophical and legal perspective. These forms are covered in an exhaustive and critical fashion, and the handbook accordingly divides in three parts: the first one introduces and discusses the basic concepts of practical reasoning. The second one discusses the main general forms of reasoning and argumentation relevant for legal discourse. The third one looks at their application in law as well as at (...) the different areas of legal reasoning. The handbook’s division in three parts reflects its conceptual architecture, since legal reasoning and argumentation are considered in relation to the more general types of reasoning. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Buddhist-Christian Studies 22 (2002) 63-76 [Access article in PDF] Formal Practice: Buddhist or Christian Robert Aitken Diamond Sangha In this paper, I write from a Mahayana perspective and take up seven Buddhist practices and the views that bring them into being, together with Christian practices that may be analogous, in turn with their inspiration. The Buddhist practices sometimes tend to blend and take on another's attributes and functions. (...) I name them according to their usage in Western Buddhism.The Nembutsu (Ch. Nien-fo, "Recalling Buddha") is the pronouncement of veneration to Amida Butsu (Ch. A-mi-to-fo, Skt. Amitabha Buddha), an appeal to his salvific power, and sometimes an endeavor to unify with him.The ekomon (Ch. hui-hsiang-men, Skt. parinamana) is a verse that transfers merit back to Buddhas, bodhisattvas, and past teachers for their further empowerment to bring beings to the way of the Buddha.Zazen (Ch. tsao-ch'an, Skt. dhyana) is focused meditation intended to enable the student to personalize the realization and way of the Buddha.The vow or expression of aspiration (J. gan, Ch. yuan,Skt. pranidhana) pronounces a determination to make realization possible for the self and others.Sange, or zange (Ch. chang-hui, Skt. kshamayati), is the confession of personal responsibility for bad karma in the past and repentance for it.Mudra(J. in, Ch. yin) and dharani(J. darani or ju, Ch. chou) are ritualized presentations of realizations and their dharma. They can be gestures, hand positions, or postures; dharaniare esoteric formulas or texts.Sutras and sutra services, from the Sanskrit (J. kyo,Ch. ching), traditional Buddhist chants and texts. The Nembutsu The Nembutsu invokes Amida, the Buddha of Infinite Light and Life and the Lord of the Pure Land, a powerful savior by dint of vows he took while still in his Bodhisattva Dharmakara incarnation. He is venerated across Asia—in Japan, Korea, Vietnam, and the Chinese diaspora. The Nembutsu formula, "Namu amida butsu," or the equivalent in the other languages ("Veneration to 'Amida Butsu'"), is repeated devotionally, bringing promise of a joyous afterlife, and for some, intimacy with Amida, [End Page 63] the spiritual oyasama, or parent, an effect not unlike that of Christian mysticism. 1 The Myokonin (Pure and Happy People), the Pure Land movement of Japanese who take it upon themselves to practice the Nembutsu moment-to-moment, set forth their experience in artless poetry that is poignant and metaphysically clear: I thought it was all due to my self-power, That [the Nembutsu] was uttered; But it was not so, it all came from the power of Oya. What I was imagining to be the other power Was no other than the self-power itself. Wishing to shun the evil path And ever hoping for the Pure land— The very thought was no other than the self-power. I have been designing all the time, Saying, "Is this the way, or that?" But there was no designing after all, All was given fully, and freely How grateful I am! Namu amida butsu! 2Interior repetition of the Nembutsu hundreds of times a day brings the fulfilling gift of spiritual intimacy with the oya, and the Christian analoy is clearly the Jesus Prayer, "Lord Jesus Christ, Son of God, have mercy on me, a sinner," or its shortened version, "Lord have mercy" ("Kyrie eleison"). 3 Yet there is more than a shade of difference between devotion to a savior empowered by his original vows for his all-embracing compassion, and devotion to the one who inherits the power of an omnipotent God. In the words of Saint Teresa of Avila, "God is almighty. His power has equaled His will; and so He can do everything that pleases him. The less I understand this, the more I believe it and the greater the devotion it arouses in me. Blessed is He forever! Amen." 4 The EkomonIn contrast to the Nembutsu, the ekomon is not an appeal for redemption but a return of the "auspicious power" (J. fukutoku, Ch. fu-tu, Skt. punya) of the sutra or sutras just recited to...

There’s a common line of reasoning which supposes that the phenomenal unity of conscious experience is grounded in a mind-like simple subject. To the contrary, Mādhyamika Buddhist philosophers like Śrīgupta (seventh–eighth century) argue that any kind of mental simple is incoherent and thus metaphysically impossible. Lacking any unifying principle, the phenomenal unity of conscious experience is instead an unfounded illusion. In this paper, I present an analysis of Śrīgupta’s "neither-one-nor-many argument" against mental simples and show how his line of reasoning (...) is driven by a set of implicit questions concerning the nature of and relation between consciousness and its intentional object. These questions not only set the agenda for centuries of intra-Buddhist debate on the topic, but they are also questions to which any defender of unified consciousness or a simple subject of experience arguably owes responses.

A significant proportion of conservationists' work is directed towards efforts to save disappearing species. This relies upon the belief that species extinction is undesirable. When justifications are offered for this belief, they very often rest upon the assumption that extinction brought about by humans is different in kind from other forms of extinction. This paper examines this assumption and reveals that there is indeed good reason to suppose current anthropogenic extinctions to be different in kind from extinctions brought about at (...) other times or by other factors. Having considered – and rejected – quantity and rate of extinction as useful distinguishing factors, four alternative arguments are offered, each identifying a way in which anthropogenic extinction is significantly different from other forms of extinction, even mass extinction: (1) Humans are a different kind of natural cause from other causes of extinction; (2) Extinctions brought about by humans are uniquely persistent; (3) Anthropogenic extinctions are effectively random whereas past mass extinctions are rule-bound; (4) The impact of the current anthropogenic extinction event differs from the impact of other extinction events of the past, such that future recovery may not follow past patterns. Together, these four arguments suggest that the present-day extinction event brought about by humans may be unprecedented and that we cannot clearly extrapolate from past to present recovery from extinctions. Although insufficient as justification for the claim that present-day extinctions are undesirable, the arguments provide some ammunition for conservationists' conviction that species extinction – in which humans play an accelerating role – ought to be prevented.

It is commonly supposed that individual animals are of little relevance to conservation which is concerned, instead, with groups of things or 'wholes' such as species, habitats, and the like. It is further contended by some that by prioritising individuals, two of those values that are held dear by conservation – namely natural selection and fitness – are compromised. Taking wildlife rehabilitation as a paradigm case of concern for the individual, it is argued that the latter claim is based upon (...) mistaken assumptions. Then, using red deer culling as a case study, the discord between conservation 's holistic values and a concern for individual worth is explored. It emerges that the conservation value of red deer culling is more apparent than real and thus that there is more room for conservationists' acceptance of individual worth than usually supposed.

BackgroundThe past 10 years have witnessed a significant growth in sharing of health data for secondary uses. Alongside this there has been growing interest in the public acceptability of data sharing and data linkage practices. Public acceptance is recognised as crucial for ensuring the legitimacy of current practices and systems of governance. Given the growing international interest in this area this systematic review and thematic synthesis represents a timely review of current evidence. It highlights the key factors influencing public responses (...) as well as important areas for further research.MethodsThis paper reports a systematic review and thematic synthesis of qualitative studies examining public attitudes towards the sharing or linkage of health data for research purposes. Twenty-five studies were included in the review. The included studies were conducted primarily in the UK and North America, with one study set in Japan, another in Sweden and one in multiple countries. The included studies were conducted between 1999 and 2013. The qualitative methods represented in the studies included focus groups, interviews, deliberative events, dialogue workshops and asynchronous online interviews.ResultsKey themes identified across the corpus of studies related to the conditions necessary for public support/acceptability, areas of public concern and implications for future research. The results identify a growing body of evidence pointing towards widespread general—though conditional—support for data linkage and data sharing for research purposes. Whilst a variety of concerns were raised in cases where participants perceived there to be actual or potential public benefits from research and had trust in the individuals or organisations conducting and/or overseeing data linkage/sharing, they were generally supportive. The studies also find current low levels of awareness about existing practices and uses of data.ConclusionsWhilst the results indicate widespread public support for data sharing and linkage for research purposes, a range of concerns exist. In order to ensure public support for future research uses of data greater awareness raising combined with opportunities for public engagement and deliberation are needed. This will be essential for ensuring the legitimacy of future health informatics research and avoiding further public controversy. (shrink)

We develop a framework for assessing security market quality, relating five elements of market design to three metrics of market integrity and two metrics of market efficiency. We empirically implement this integrity–efficiency MQ framework by testing a hypothesis that trade-based ramping manipulation at the close raises execution costs on 24 security markets worldwide. Estimating a simultaneous equations model of ramping incidence, spreads, and the probability of deploying real-time surveillance, we show that quoted bid-ask spreads are positively related to the incidence (...) of MTC across seven liquidity deciles. The magnitude is economically significant; improving market integrity by cutting MTC in half reduces spreads 6–11 %. Allowing direct market access in conjunction with RTS, conducting auctions at the close, and developing regulations that require surveillance, all reduce MTC and thereby lower spreads, assuring better market integrity and enhancing market efficiency. Introducing circuit breakers or prohibiting shorts poses integrity–efficiency tradeoffs. (shrink)

Abela and Murphy (J Acad Mark Sci 36(1):39–53, 2007 ) examined Service-Dominant (S-D) logic (Vargo and Lusch, J Mark 68(1):1–17, 2004 ) from the viewpoint of Marketing Ethics and concluded that whilst S-D logic does not have explicit ethical content, the Foundational Premises (FPs) of S-D logic do have implicit ethical content. They also conclude that what may be needed to make the implicit more explicit is the addition of another FP. The aim of this article is to explore whether (...) S-D logic needs to be modified, if one wishes to construct a theoretical framework for analysis of Marketing that has ethical considerations fully integrated. We critically evaluate the claim that the FPs are inherently ethical and conclude that S-D logic should be modified. We offer an additional FP for consideration that relates to the role of personal and societal values in the co-creation of value. This FP is necessary because of the role that the ethical positions of actors play in exchange behaviour. However, it should be pointed out that whilst the article explores the ethical potential of S-D logic it does not privilege any particular ethical position or code. These concerns will be addressed in subsequent articles: the aim here is to establish the underlying rationale for including an explicit commitment to ethics in S-D logic. (shrink)

This chapter presents an overview of the life, work, and philosophical contributions of Śāntarakṣita (c. 725–788), who is known for his synthesis of Nāgārjuna’s Madhyamaka with elements of the Dignāga-Dharmakīrti tradition of logic and epistemology. His two most important independent treatises, the Compendium of True Principles (Tattvasaṃgraha) and the Ornament of the Middle Way (Madhyamakālaṃkāra), are characterized by an emphasis on the indispensable role of rational analysis on the Buddhist path as well as serious and systematic engagement with competing Buddhist (...) and non-Buddhist schools of thought. Śāntarakṣita employs a pedagogical-rhetorical device of provisionally adopting what he deems to be successively more rational views to reject less rational ones. Using this approach, in the Ornament of the Middle Way, he recommends a gradual path to arrive at an understanding of the Madhyamaka ultimate truth by incorporating Yogācāra idealist ontology into his presentation of conventional truth. In this same text, he presents an influential iteration of the neither-one-nor-many argument for the Madhyamaka ultimate truth, the emptiness of intrinsic nature—i.e., the universal negation of ontologically independent being—leaving a lasting and significant impact on both Indian and Tibetan Madhyamaka Buddhist philosophy.

Canonical defenders of the principle of sufficient reason (PSR), such as Leibniz and Spinoza, are metaphysical foundationalists of one stripe or another. This is curious since the PSR—which says that everything has a ground, cause, or explanation—in effect, denies fundamental entities. In this paper, I explore the apparent inconsistency between metaphysical foundationalism and approaches to metaphysical system building that are driven by a commitment to the PSR. I do so by analyzing how Indian Buddhist philosophers arrive at foundationalist and anti-foundationalist (...) positions motivated by implicit commitments to different versions of the PSR. I begin by introducing the Buddhist principle of dependent origination (pratītyasamutpāda) as a proto-PSR that is restricted to causal explanation. Next, I show how Vasubandhu’s Sautrāntika Abhidharma metaphysics is shaped by a qualified commitment to both causal and metaphysical grounding versions of the PSR. I then reveal how Nāgārjuna’s Madhyamaka metaphysics is driven by an unrestricted and exceptionless commitment to causal and metaphysical grounding versions of the PSR. Finally, I consider how Nāgārjuna’s account may put him in a unique position to respond to a common contemporary objection to the PSR from necessitarianism. I conclude by addressing a competing interpretation on which Nāgārjuna is best understood as an anti-rationalist rather than an uber-rationalist, as I characterize him. (shrink)

According to Madhyamaka Buddhist philosophers, everything depends for its existence on something else. But what would a world devoid of fundamentalia look like? In this paper, I argue that the anti-foundationalist “neither-one-nor-many argument” of the Indian Mādhyamika Śrīgupta commits him to a position I call “metaphysical indefinitism.” I demonstrate how this view follows from Śrīgupta’s rejection of mereological simples and ontologically independent being, when understood in light of his account of conventional reality. Contra recent claims in the secondary literature, I (...) clarify how the Madhyamaka metaphysical dependence structure is not a straightforward infinitism since it does not honor strict asymmetry or transitivity. Instead, its dependence relations are irreflexive and extendable, admitting of dependence chains of indefinite (though not actually infinite) length and dependence loops of non-zero length. Yet, the flexible ontology of Śrīgupta's Madhyamaka can accommodate a contextualist account of asymmetry and support a revisable theory of conventional truth, delivering significant payoffs for the view, including the capacity to accommodate developments in scientific explanation.

One of the central concepts in rabbinic Judaism is the notion of the Evil Inclination, which appears to be related to similar concepts in ancient Christianity and the wider late antique world. The precise origins and understanding of the idea, however, are unknown.

The chapters, which cover a wide range of sources including the Bible, the Ancient (...) Versions, Qumran, Pseudepigrapha and Apocrypha, the Targums, and rabbinic and patristic literature, advance our understanding of the intellectual exchange between Jews and Christians in classical Antiquity, as well as the intercultural exchange between these communities and the societies in which they were situated.

In lieu of an abstract, here is a brief excerpt of the content:Who Hears?A Zen Buddhist PerspectiveRobert AitkenWestern psychologists and neurologists have attempted to use their concepts to explain East Asian religions for more than seventy-five years. Carl Jung (1875–1961) wrote a long foreword to Richard Wilhelm's The Secret of the Golden Flower back in 1931, which gave many readers in Europe and the Americas their first glimpse of philosophical Daoism.1 A generation later, Erich Fromm's conversations with D. T. Suzuki (...) were recorded in Zen Buddhism and Psychoanalysis.2 In our own time, the Dalai Lama's collaborative work with neuroscientists and psychologists has received widespread attention,3 while academia has given James H. Austin's Zen and the Brain hearty approval.4The process of mutual understanding between Western scientists and teachers of East Asian religion is still incomplete, however, and in earlier times it had barely begun. I remember my amusement back in the 1970s, watching a video of monks trailing streams of wires attached to biofeedback instruments while they were walking formally and solemnly. Even in those early days it was apparent to me that for all their academic credentials, the scholars had started with an ignorance of the subject of their study. They were successful in measuring something in the brain relating to a samādhi condition, but while the monks may have grounded themselves more or less in a settled practice, who is to measure their appreciation of the mejiro chirping in the camellia bush just outside? Great masters of Zen, Zhaozhou, and Deshan and their successors did not talk about being settled, any more than neuroanataomists discuss the importance of the alphabet.The chirping of the mejiro might have reminded the monks of a case, a case that would lie in a dimension even further from the world of wires and dials. "Who is the master of hearing that sound?"5 This was the gist of a question by Bassui Tokushō Zenji—a question that became a public case, one kōan among many other kōans that have not been studied by science. It is time for such a study.My directory of Chinese kōans holds more than 5,500 neatly framed traditional stories set forth to guide the student.6 The modern Zen teacher is conversant with some 550 of these kōans, a number that is sufficient if... if.... There are several caveats. If the teacher treats kōans as historical artifacts, then the stories are no [End Page 89] longer kōans, and the teaching is perniciously misleading. Sometimes the teacher has gone only part way in kōan study. The great house of conventional wisdom has fallen, but he or she doesn't know it is ruined and holds forth in the old explanatory way. Sometimes the teacher has completed the long course of study, but elects to pontificate from within the wreckage of the old manor. Finally there are those who abandon the ruins completely for practice on the open road. Here is my gāthā pointing to that way:Stepping forth on the open road,I vow with all beingsTo distinguish the voices of birds,And make good use of my time.Bassui Zenji's kōan "Who is the master of hearing that sound?" could be paraphrased here at the Pālolo Zen Center as "Who is hearing that thrush singing on the railing outside?" If, in the days before I retired, a student were to respond, "I hear the thrush," I would not have approved. Bassui would not have approved. Intimacy would be missing, and intimacy is the Dao. Intimacy is the way of all the Buddhas. There is no Zen without intimacy; intimacy with what? Both the self and the thrush. That was Bassui's intention, you can be sure.Fayan met Dizang while on pilgrimage. Dizang asked, "What are you up to these days?"Fayan said, "I'm going around one pilgrimage, wherever my feet will carry me."Dizang asked, "What to you expect from pilgrimage?"Fayan said, "I don't know."Dizang said, "Not knowing is most intimate." Fayan underwent great realization. 7Zen Buddhism stresses intimacy, while in... (shrink)

Longchen Rabjampa (1308–64), scholar of the Tibetan Buddhist Nyingma tradition, presents a novel doxographical taxonomy of the so-called Svātantrika branch of Madhyamaka Buddhist philosophy, designating the Indian Mādhyamika Śrīgupta (c. 7th/8th century) as the exemplar of a Svātantrika sub-school which maintains that appearance and emptiness are metaphysically distinct. This paper compares Longchenpa’s characterization of this “distinct-appearance-and-emptiness” view with Śrīgupta’s own account of the two truths. I expose a significant disconnect between Longchenpa’s Śrīgupta and Śrīgupta himself and argue that the impetus (...) for Longchenpa’s doxographical innovation originates not in Buddhist India, but within his own Tibetan intellectual milieu, tracing back to his twelfth-century Sangpu Monastery predecessors, Gyamarwa and Chapa.

Innes’s “control signals” provides a semiotic perspective for explaining how acts of social control send “signals” about the effectiveness of security mechanisms. A cross-cutting theme infers that “culture and situation matter” in the reception of signals. However, the control signals concept does not explicitly consider the influence that prior experiences may have on present interpretations. Drawing on qualitative research into how members of a residential community perceived control measures within their everyday environment for Glasgow’s 2014 Commonwealth Games, this article outlines (...) the importance of the “pre-signalling” context in influencing how control signals are received. Goffman’s “frame analysis” is used as part of a semiotic framing approach to demonstrate that control signals are framed (or pre-signalled) by the history of relations between sender and receiver of the signal (for example, police and residents).

Dharmakīrti’s (c. seventh century) Examination of Relations (Sambandhaparīkṣā) is unique in the Indian Buddhist canon for its being the only extant root text devoted entirely to the topic of the ontological status of relations. But the core thesis of this treatise—that relations are only nominally real—is in prima facie tension with another claim that is central to Dharmakīrti’s epistemology: that there exists some kind of “natural relation” (svabhāvapratibandha) that reliably underwrites inferences. Understanding how Dharmakīrti can consistently rely on natural relations (...) to prop up his presentation of inferential reasoning while at the same time advancing an anti-realist account of relations is critical for making sense of his system of logic and epistemology, which came to be nearly universally adopted in Tibetan Buddhism cutting across traditions. Chomden Rikpé Reldri (1227–1305), who was perhaps the most prolific commentator on logic and epistemology in the history of Tibetan philosophy, composed two texts commenting on the Examination of Relations, neither of which have received any scholarly attention to date. In this paper, I provide an introduction to Chomden Reldri’s two commentaries and consider how they may illuminate Dharmakīrti’s text and also what they reveal about the understanding of Dharmakīrti’s account of relations in early Tibetan scholasticism. I then present a translation of Dharmakīrti’s Examination of Relations together with Chomden Reldri’s commentary, Annotations and Topical Outline of the Examination of Relations (’Brel pa brtag pa’i mchan dang sa bcad gnyis).

Current attention directed at ethical dimensions of data and Artificial Intelligence have led to increasing recognition of the need to secure and maintain public support for uses of people’s data. This is essential to establish a “Social Licence” for current and future practices. The notion of a “Social Licence” recognises that there can be meaningful differences between what is legally permissible and what is socially acceptable. Establishing a Social Licence entails public engagement to build relationships of trust and ensure that (...) practices align with public values. While the concept of the Social Licence is well-established in other sectors – notably in relation to extractive industries – it has only very recently begun to be discussed in relation to digital innovation and data-intensive industries. This article therefore draws on existing literature relating to the Social Licence in extractive industries to explore the potential approaches needed to establish a Social Licence for emerging data-intensive industries. Additionally, it draws on well-established literature relating to trust to examine the relevance of trust, and trustworthiness, for emerging practices in data-intensive industries. In doing so the article considers the extent to which pursuing a Social Licence might complement regulation and inform codes of practice to place ethical and social considerations at the heart of industry practice. We focus on one key industry: Financial Technology. We demonstrate the importance of combining technical and social approaches to address ethical challenges in data-intensive innovation and to establish relationships of trust to underpin a Social Licence for Financial Technology. Such approaches are needed across all areas and industries of data-intensive innovation to complement regulation and inform the development of ethical codes of practice. This is important to underpin culture change and to move beyond rhetorical commitments to develop best practice putting ethics at the heart of innovation. (shrink)

What are the opportunities for the maximum happiness, greatest satisfaction, and fulfilment of all in the business organisation? What quality of life can we have at work?

The digitization of society and academic research endeavours have led to an explosion of interest in the potential uses of population data in research. Alongside this, increasing attention is focussing on the conditions necessary for maintaining a social license for research practices. Previous research has pointed to the importance of demonstrating “public benefits” from research for maintaining public support, yet there has been very little consideration of what the term “public benefits” means or what public expectations of “public benefits” are. (...) In order to address this pressing issue a series of deliberative workshops with members of the public were held across Scotland in May and June 2017. The workshops aimed to engage a cross-section of the Scottish population in in-depth discussions of the ways that the public – or publics – might benefit from data-intensive health research. The findings reported here discuss workshop participants’ understandings and expectations of health research; who they considered to be “the public” that should benefit from health research and; in what ways they felt “the public” should benefit. Workshop participants’ preference was clearly for the widest possible public benefit to be felt by all, but they also acknowledged the value in research aiming to primarily benefit vulnerable groups within society. A key focus of discussions was the extent to which workshop participants were confident that potential public benefits would be realised. A crucial consideration then is the extent to which mechanisms and political support are in place to realise and maximise the public benefits of data-intensive health research. (shrink)

Jan Westerhoff defends an account of thoroughgoing non-foundationalism that he calls “irrealism,” which is implicitly modeled on a Madhyamaka Buddhist view. In this paper, I begin by raising worries about the irrealist’s account of human cognition as taking place in a brain-based representational interface. Next, I pose first-order and higher-order challenges to how the irrealist—who defends a kind of global error theory—can sensibly accommodate an unlocalized appearance-reality distinction, both metaphysically and epistemologically. Finally, although Westerhoff insists that irrealism itself is not (...) an ontological theory and that the irrealist’s rejection of absolutely general quantification precludes his commitment to any ultimately true theories, I propose strategies inspired by the Svātantrika commentarial tradition of Madhyamaka for how the irrealist might develop a lightweight account of unrestricted quantification that could be used to advance a lightweight ultimately true theory. This, I suggest, may allow the irrealist to (i) preserve a commitment to an unlocalized appearance-reality distinction, (ii) underwrite a distinction between ordinary veridical states and metaphysically accurate epistemic states, and (iii) provide an explanation for the massive error that he claims characterizes ordinary cognition.

A number of recent developments in our understanding of the biology of heritability question commonly held views on the immutability of genetic factors. These have numerous potential implications for improving understanding and practice in pre- and postconceptional care and for infant and child mental health, and they carry a cautionary message against overgeneralization.

This paper outlines some of the moral issues I faced when working in the field with homeless children and children with cerebral palsy. Bill Bunge argues that the 'immediacy' of fieldwork requires that we divest ourselves of theoretical and philosophical pretensions to attend the urgency of our participants' context. I use personal examples of powerful and contradictory experiences from working with young people in the field to highlight the importance of a moral integrity that recognizes vulnerability and the needs of (...) the moment.

It pertains to a problem which we cannot ignore today, namely that of thinking the place of science in the context of the entirety of our experience, whether in order to maintain a critique of the former, as has been done after Bergson (and in ways other than his own), for example by Deleuze or Merleau-Ponty; or to continue to deepen it, as has been done after Brunschvicg (and in ways other than his own) for example by Bachelard or Cavaillès. (...) Without revisiting these two doctrines, we can understand neither the problem nor the way in which it continues to problematise the philosophical enterprises that have succeeded it, up to the present day.1.

This monograph includes an analysis of the Commentary on the Introduction to Reality (Tattvāvatāravṛtti) by the Indian Madhyamaka Buddhist philosopher, Śrīgupta (7th/8th century), together with a Tibetan critical edition and annotated translation of this text, which has never before been available in English. In this work, Śrīgupta advances the “neither-one-nor-many argument,” which sets out to prove that all things lack ontological independence, and by implication, that everything depends for its existence on something else. I present a detailed reconstruction and analysis (...) of the argument, showing how Śrīgupta rejects the possibility of ontological independence by way of rejecting the possibility of mereological simples, both material and immaterial. Śrīgupta's other important philosophical contributions are brought to light, including his influential threefold criterion for conventional reality (saṃvṛtisatya) and his argument for the possibility of conceptual enlightened cognition (vikalpajñāna), which is standardly supposed to be non-conceptual.

Both fairness and efficiency are important considerations in market design and regulation, yet many regulators have neither defined nor measured these concepts. We develop an evidencebased policy framework in which these are both defined and measured using a series of empirical proxies. We then build a systems estimation model to examine the 2003–2011 explosive growth in algorithmic trading on the London Stock Exchange and NYSE Euronext Paris. Our results show that greater AT is associated with increased transactional efficiency and reduced (...) information leakage in top quintile stocks. For less liquid stocks, manipulation at the close declines. We also document the tradeoff between reduced spreads and increased manipulation or information leakage following the introduction of MiFID1. (shrink)

Although the generation of reactive oxygen species is an activity normally associated with phagocytic leucocytes, mammalian spermatozoa were, in fact, the first cell type in which this activity was described. In recent years it has become apparent that spermatozoa are not the only nonphagocytic cells to exhibit a capacity for reactive oxygen species production, because this activity has been detected in a wide variety of different cells including fibroblasts, mesangial cells, oocytes, Leyding cells endothelial cells, thryroid cells, adipocytes, tumour cell (...) and platelets. Since the capacity to generate reactive oxygen species is apparently so widespread, the risk‐benefit equation for these potentially pernicious molecules becomes a matter of intese interest. In the case of human spermatozoa, the risk of manufacturing reactive oxygen metabolites is considerable because these cells are particularly vulnerable to lipid peroxidation. Indeed, there is now good evidence to indicate that oxygen radicals are involved in the initiation of peroxidative damage to the sperm plasma membrane, seen in many cases of male infertility. This risk is off‐set by recent data suggesting that superoxide anions and hydrogen peroxide also participate in the induction of key biological events such as hyperactiavated motility and the acrosome reaction. Thus, human spermatozoa appear to use reactive oxygen species for a physiological purpose and have the difficult task of ensuring the balanced generation of these potentially harmful, but biologically important, modulators of cellular function.

Introduction The provision of abortion services in the Republic of Ireland is legally restricted. Recent legislation that has been implemented allows for abortion if there is a real and substantial risk to the woman's life, but in general Irish women must travel abroad for abortion services. The aims of this study were to investigate the clinical experiences of Irish obstetric non-consultant hospital doctors that work in this environment and to assess their attitudes towards termination of pregnancy. Methods We conducted an (...) online cross-sectional descriptive survey of 184 Irish obstetric NCHDs. Quantitate and qualitative analysis was performed. Results There was a 28% response rate. 88% of respondents thought that ToP should be permitted for fatal fetal abnormality if the parents choose, 96% if the woman's health is severely affected and 86% in cases of rape and incest. Over 90% of respondents believed a woman's health suffers because of the need to travel abroad to undergo a ToP. Physical, psychological and social reasons were explored. The research also highlights that obstetric trainees are actively involved in the provision of preabortion and postabortion care. Conclusions The clinical experiences and opinions of the respondents suggest that the current legal availability of abortion in Ireland is insufficient to guide best clinical practice and does not represent the views of those that provide obstetric care.

Most healthcare providers work from ethical principles based on a Western model of practice that may not adhere to the cultural values intrinsic to Indigenous peoples. Breaking bad news is an important topic of ethical concern in health research. While much has been documented on BBN globally, the ethical implications of receiving bad news, from an Indigenous patient perspective in particular, is an area that requires further inquiry. This article discusses the experiences of Māori lung cancer patients and their families, (...) in order to investigate the ethical implications of receiving bad news. Data collection occurred through 23 semistructured interviews and nine focus groups with Māori lung cancer patients and their families in four districts in the Midland Region of New Zealand: Waikato, Bay of Plenty, Lakes and Tairāwhiti. The findings of this study were categorised into two key themes: communication and context. Avenues for best practice include understanding the centrality of the HCP–patient relationship and family ties in the healthcare journey, and providing patients with the full range of viable treatment options including hope, clear advice and guidance when the situation calls for it. Overall, the findings of this study hold implications for providing culturally safe and humanistic cancer care when BBN to Māori and Indigenous patients. (shrink)
