Anti-selection occurs when information asymmetry exists between insurers and applicants. When an applicant knows they are at high risk of loss, but the insurer does not, the applicant may try to use this knowledge differential to secure insurance at a lower premium that does not match risk.

In free and open source software (FOSS), computer code is made freely accessible and can be modified by anyone. It is a creative domain with many unique features; the FOSS mode of creativity has also influenced many aspects of contemporary cultural production. In this article we identify a number of fundamental but unresolved general issues in the study of creativity, then examine the potential for the study of FOSS to inform these topics. Archival studies of the genesis of FOSS projects, (...) coupled with laboratory studies detailing the psychological processes involved in software creation, can provide converging evidence on the nature of creativity in software design. Such a research program has broad implications both for theories of creativity and for real-world innovation in software and other forms of digital cultural production. (shrink)

Nāgārjuna contends that the doctrine of Pratītyasamutpāda , properly understood, constitutes the philosophical basis for the rejection and avoidance of all metaphysical theories and concepts . The companion doctrine of "śūnyatā" constitutes the denial of metaphysical realism but does not imply an anti-realist, conventionalist view of reality . "Pratītyasamutpāda," the true doctrine or, literally, "the exact or real nature of the case," is really two-sided: it is a "causal" principle explaining the origin of all that exists, and a semantic principle (...) concerning the mutual dependency of concepts and beliefs in both the systematic and historically contingent sense. The latter implies a pragmatic approach to meaning. (shrink)

We prove a finite model theorem and infinitary completeness result for the propositional -calculus. The construction establishes a link between finite model theorems for propositional program logics and the theory of well-quasi-orders.

In this paper we provide a psychological account of the nature and development of explanation. We propose that an explanation is an account that provides a conceptual framework for a phenomenon that leads to a feeling of understanding in the reader/hearer. The explanatory conceptual framework goes beyond the original phenomenon, integrates diverse aspects of the world, and shows how the original phenomenon follows from the framework. We propose that explanations in everyday life are judged on the criteria of empirical accuracy, (...) scope, consistency, simplicity, and plausibility. We conclude that explanations in science are evaluated by the same criteria, plus those of precision, formalisms, and fruitfulness. We discuss several types of explanation that are used in everyday life – causal/mechanical, functional, and intentional. We present evidence to show that young children produce explanations that have the same essential form as those used by adults. We also provide evidence that children use the same evaluation criteria as adults, but may not apply those additional criteria for the evaluation of explanations that are used by scientists.

According to many critics, Descartes argued in a circle when he presumed to base the certainty (and thus knowledge) of propositions that fulfill his epistemic criterion of being “clearly and distinctly perceived” on the demonstration that God exists and is not a deceiver. But his critics say, that demonstration, as he presented it, presupposed the validity of the same epistemic criterion. I critically examine two major strategies to dispel the appearance of circularity, two ways of interpreting Descartes’ argument.My approach shares (...) with the second strategy the contention that Descartes did adopt the principle that “whatever is clearly and distinctly perceived to be true is true,” prior to his consideration of the God question. Moreover, his demonstration of God’s existence and veracity made use of the principle. But my claim is that the knowledge of God’s existence and veracity is not used to validate the principle of clear and distinct perception (that would be unnecessary). It is used rather to defeat the sceptic’s argument that we cannot have any knowledge of the external, physical world. I proceed to present and explain Descartes’ argument centered around the thesis, “I cannot be certain that (r) any of my representational ideas of the external world are veridical, unless I am certain that (q), God exists and is not a deceiver.” That is, I prove why, for Descartes, (q) is necessary for (r). My discussion exposes some new facets to the principle of clear and distinct perception and reveals the fact that some familiar Cartesian distinctions that were not thought to be relevant to the problem of the Cartesian Circle are crucial to the solution of that problem.

Chad Hansen is one of the strongest proponents of the view that the important second chapter of Zhuangzi's Inner Chapters (The Qi Wu Lun) reveals Zhuangzi to be a relativistic sceptidst. Hansen argues that Zhuangzi is a sceptic because he is first and foremost a relativist. Hansen's argument is essentially that Zhuangzi's perspectivism, his belief that one's linguistic and conceptual perspective determines what one claims to know, makes him a thorough going relativist and sceptic. I agree that Zhuangzi is a (...) perspectivist, but disagree with Hansen's portrayal of him as a relativistic sceptic. I first show that there is an important ambiguity in Hansen's argument. I then proceed to argue that important passages in the Qi Wu Lun (in particular the butterfly dream passage,) reveal serious problems with Hansen's interpretation of Zhuangzi's philosophical stance, I maintain that Zhuangzi is neither a sceptic nor a perspectival relativist. He is rather a perspectival realist. (shrink)

This paper argues that the central philosophical movement in the complex history of Buddhism that originated with Siddhartha Gautama, the Buddha and carried on by Nāgārjuna (among other later Buddhist philosophers) shares some common themes with the pragmatic philosophy of John Dewey. These themes are the rejection of traditional metaphysics as definitive of philosophy, a return to the correct understanding of the nature of experience, and a particular view about the conduct and nature of philosophy. Dewey is used to illuminate (...) such controversial problems in the Buddhist tradition as why the Buddha is silent about metaphysical questions, what it means to say that everything is anitya, and how we are to understand Nāgārjuna's key concepts of prattyasamutpāda and únyatá.

BackgroundThe Mental Capacity Act was enacted in 2007 in England and Wales, but the assessment of mental capacity still remains an area of professional concern. Doctors’ compliance with legal and professional standards is inconsistent, but the reasons for poor compliance are not well understood. This preliminary study investigates doctors’ experiences of and attitudes toward mental capacity assessment.MethodsThis is a descriptive, cross-sectional study where a two-domain, study-specific structured questionnaire was developed, piloted and digitally disseminated to doctors at differing career stages employed (...) in a large, multi-site National Health Service Trust in London over 4 months in 2018. Descriptive statistics and frequency tables adjusted for missing data were generated and secondary analysis was conducted.ResultsParticipants were predominantly UK trained, female and between the ages of 30 and 44 years. Less than half of the participants reported receiving formal MCAx training. Only one-third of the participants self-rated themselves as very competent or extremely competent. Self-reported MCA confidence was significantly affected by career stage with Consultants with over 10 years of experience reporting lowest confidence.ConclusionsThis study describes significant variation in practice by doctors and low self-confidence in the practice of MCAx. These results raise concerns that MCAx continues to be inconsistently performed by doctors despite appropriate awareness of the law and professional guidance on best practice. (shrink)

Nāgārjuna contends that the doctrine of Pratītyasamutpāda (dependent origination), properly understood, constitutes the philosophical basis for the rejection and avoidance of all metaphysical theories and concepts (including causation). The companion doctrine of "śūnyatā" constitutes the denial of metaphysical realism (or "essentialism") but does not imply an anti-realist, conventionalist view of reality (as Jay Garfield maintains). "Pratītyasamutpāda," the true doctrine or, literally, "the exact or real nature of the case," is really two-sided: it is (1) a "causal" principle explaining the origin (...) of all that exists, and (2) a semantic principle concerning the mutual dependency of concepts and beliefs in both the systematic and historically contingent sense.

While Stephen Davies argues that a debate on cross-cultural aesthetics is possible if we adopt an attitude of mutual respect and forbearance, his fellow symposiasts shed light upon different aspects which merit a closer scrutiny in such a dialogue. Samer Akkach warns that an inclusivistic embrace of difference runs the risk of collapsing the very difference one sought to understand. Julie Nagam underscores that local knowledge carriers and/or the medium should be involved in such a cross-cultural exploration. Enrico Fongaro searches (...) for a way of experiencing cross-cultural art such that it can lead to a transformative experience Relatedly, Meilin Chinn uses the analogy of friendship to explore the edifying dimension of experiencing an art form.

It is shown that over any countable first-order structure, IND programs with dictionaries accept exactly the Π 1 1 relations. This extends a result of Harel and Kozen 118) relating IND and Π 1 1 over countable structures with some coding power, and provides a computational analog of a result of Barwise et al. 108) relating the Π 1 1 relations on a countable structure to a certain family of inductively definable relations on the hereditarily finite sets over that structure.

This paper presents a cognitive account of the process of evaluating scientific data. Our account assumes that when individuals evaluate data, they construct a mental model of a data-interpretation package, in which the data and theoretical interpretations of the data are integrated. We propose that individuals attempt to discount data by seeking alternative explanations for events within the mental model; data-interpretation packages are accepted when the individual cannot find alternative accounts for these events. Our analysis indicates that there are many (...) levels at which data-interpretation packages can be accepted or denied. (shrink)

Did the Carthaginian cavalry general Maharbal really urge Hannibal to march on Rome after Cannae, and then comment bitterly Vincere sets, Hannibal; victoria uti nescis, when his leader refused? There are two main objections: Maharbal may not have been there, and anyway Cannae was too far away to justify such a march. The whole story has been seen as one of those well-known Roman historiographical inventions. But there may well be more to the story than that, illuminating both Hannibalic history (...) and some Roman historiographical techniques. (shrink)

Development of the knowledge base for a profession depends on research and scholarship that builds on the insights and work of scholars within the discipline and is disseminated through the literature. The purpose of this study was to examine a unique collection of 79 articles selected by editors as representative of their nursing journals. Articles were assessed for congruence with long‐standing values and conceptual definitions of nursing, and the extent to which they built on prior literature published in nursing. Articles (...) were scored based on whether they reflected four characteristics of nursing as a discipline (holism, social context, goal of health, and consistency with common definitions of nursing); an abstract score on the extent to which the title, abstract, or keywords indicated a general focus on nursing; and a distinction score based on whether the article distinguished nurses or nursing from other providers. Fifty of the articles received an article score of 4, indicating all four disciplinary characteristics were present in the article's content. While the majority of the articles were congruent with fundamental nursing values and perspectives, only 28% of the sources cited were from nursing sources. The lack of citations to nursing literature, coupled with an assessment that reveals gaps in substantive content that builds on nursing knowledge, raises questions about the future of nursing perspectives in the literature.

This dialogue introduces the concepts of colonization and decolonization of nursing knowledge, the harms that have come from colonization, and the importance of engaging in the processes of decolonization as a means of achieving social justice and humanization for all. Specific options to decolonize nursing knowledge are discussed.

Ji Kang's 嵇康 argument against the presence of emotions in music in “Sound Has Neither Sorrow nor Joy” (sheng wu ai le lun 聲無哀樂論) relies centrally on his claim that harmonious sounds are “without image” (wu xiang 無象). In contrast, the Ru 儒 (Confucian) view of music is that it transmits images and emotions between musicians and listeners, which provides the basis for the musical cultivation of virtue (de 德). In this paper, I provide a reading of Ji Kang's argument (...) that elucidates key differences between music with and without images, and offer an analysis of these differences in terms of intransitive musical meaning.

In lieu of an abstract, here is a brief excerpt of the content:Nāgārjuna's Fundamental Doctrine of PratītyasamutpādaEwing ChinnIt seems fitting that the very last verse of Nāgārjuna's challenging work, Mūlamadhyamakakārikā (Fundamental Verses of the Middle Way), would present the reader with what seems to be a riddle: "I prostrate to Gautama, who through compassion, taught the true doctrine, which leads to the relinquishing of all views" (27 :30). This should be read with an earlier verse (13 : 8): "The victorious (...) ones have said that emptiness is the relinquishing of all views. For whomever emptiness is a view, that one will accomplish nothing."1 Since the last chapter deals with questions about the self and the world, it is understandable that so many commentators would assume that the "true doctrine" of which Nāgārjuna speaks is the doctrine of śūnyatā, but that gives a paradoxical character to these verses. Gautama recommends to us a doctrine that all this (we and all that we experience of the world) is śūnya, that is, empty of essence and thus of inherent, independent existence. And does this anti-realist, anti-essentialist view of things (as some would interpret śūnyatā) make possible and even constitute the relinquishing of all views, including his own? It cannot simply be the trivial and disingenuous claim that to accept the truth of śūnyatā is to relinquish all other wrong views. So is Nāgārjuna mysteriously refuting himself? Or is he uttering a paradox?I will argue that there is no paradox or problem of self-refutation, because the true doctrine that Nāgārjuna refers to is not śūnyatā but the doctrine of pratītyasa-mutpāda (dependent arising or origination). And what the verses assert is that if we understand and accept this doctrine, we will no longer have the need or inclination to hold any view about the nature of things, including the inclination to construct a view out of the declaration that "all this is śūnya." How this is possible, how accepting the doctrine makes possible the "relinquishing of all views," certainly depends on what kind of doctrine this is and how it is to be distinguished from a "view." Part of my argument, of course, is that neither pratītyasamutpāda nor the assertion that "all this is śūnya" should be taken as even implying any metaphysical views—either nihilism, absolutism, or anti-realism (the most common metaphysical interpretations). There is no doubt that a major target of Nāgārjuna's philosophical criticism is metaphysical realism. But this does not mean that the critic must hold some alternative metaphysical view.The logical place to begin is chapter 1, "Examination of Conditions," where the subject of discussion is the concept of pratītyasamutpāda, but it is not clear at all what Nāgārjuna is trying to establish about this concept. Jay Garfield, in his recent translation of and commentary on the Mūlamadhyamakakārikā titled The Fundamental Wisdom of the MiddleWay, offers a unique interpretation of the point of this chapter, [End Page 54] and I will follow him to some extent in his analysis of the text.2 However, we will part ways at a crucial point in the chapter with regard to what Nāgārjuna is about.On the Nature and Significance of PratītyasamutpādaIn this first chapter, Garfield notes that "Nāgārjuna distinguishes two possible views of dependent origination or the causal process—one according to which causes bring about their effects in virtue of causal powers and one according to which causal relations simply amount to explanatorily useful regularities—and defends the latter."3 That is to say, according to Garfield, Nāgārjuna defends pratītyasamutpāda as a regularity or Humean theory of causation against an essentialist or realist interpretation. The latter contends that while we may cite one or more factors or events as the causal condition of some effect, it is the force or power in these conditions that is actually the cause of the effect. Nāgārjuna's basic criticism of this realist view is summarized in the fourth verse:Power to act does not have conditions. There... (shrink)

The fact that racism and other forms of discrimination and injustice have persisted in our own nursing communities despite our rhetoric of caring and compassion can no longer be denied.

The authors of the articles in this issue are giving us the precious gift of their (...) ideas. All of us, white scholars and scholars of color, must come together to receive this gift, learn from their words and their insight, debate the ideas, honor the perspectives, and consider ways that we can move this discourse forward to create new possibilities for nursing, new possibilities to shape the future development of our discipline.

The claim that there are incommensurable conceptual schemes through which different cultures see the world (or see their worlds) poses a challenge to the viability of comparative philosophy that cannot be easily dismissed. Donald Davidson’s famous attack on the very idea of alternative conceptual schemes through his rejection of the “third dogma of empiricism,” the dogma of the absolute distinction between scheme and content, has never been very well understood. I will argue that the rejection of the dogma enables Davidson (...) to adopt a realist position (as opposed to the anti-realist position of Rorty, who endorses the rejection)and forms the basis for his theory of radical interpretation, supported by his “principle of charity.” And I will use John Dewey’s “postulate of immediate empiricism” to explain Davidson’s views. Together they provide a way to meet the challenge of conceptual relativism. (shrink)
