Under the impact of cultural, economic and legislative forces the traditional role of the university health center is changing. The academic health center is rapidly evolving from a relatively undifferentiated general hospital, primarily responsible for the education of undergraduate students of medicine, into a center of clinical research, caring for very specialized mixes of patients, and having as its primary educational mission the training of subspecialists. The nature of the forces responsible for this change are analyzed, and some of its (...) possible consequences for the definition of quality health care, for the shape of medical practice and medical education, and for the allocation of resources for health care are explored. This exploration suggests that the functional separation of the medical school from the highly technical, clinical research center is inevitable. This in turn may exacerbate tensions within medicine between the physician as scientist and as healer, between curative and preventive practice and between personal and public health. Although the effects of this separation on medical education remain obscure, it has already occasioned the most comprehensive review of the medical curriculum since the time of Flexner. Out of this is likely to develop a more generalist view of the education of future physicians. (shrink)

The authors, on the basis of brief arguments, have dismissed tensor networks as a viable response to Jackendoff's challenges. However, there are reasons to believe that connectionist approaches descended from tensor networks are actually very well suited to answering Jackendoff's challenges. I rebut their arguments for dismissing tensor networks and briefly compare the approaches.

Patient safety has only recently been subjected to wide-spread systematic study. Healthcare differs from other high risk industries in being more diverse and multi-contextual, and less certain and regulated. Also many patient safety problems are low-frequency events associated with many, varied contributing factors. The subject of this paper is the epistemology of patient safety (the science of the method of finding out about patient safety). Patient safety research is considered here on the background of a risk management framework which requires (...) researchers to: • Understand the context - as a subset of healthcare quality, services and systems research, with technical and human behavioural (cultural) components and a range of external and internal organisational influences, a wide range of research disciplines is necessary • Identify the risks - identify the things that go wrong and the frequency and nature of different types of incidents from sources such as medical record review, observational studies, audit, incident and medico-legal reports • Analyse the risks - deconstruct the things that go wrong, identifying contributing factors and trying to detect trends and patterns in contributing factors, detection, mitigation factors, ameliorating factors and actions taken to reduce risk • Evaluate the risks - decide on priorities, identifying preventive and corrective strategies and judging the risk- and cost-benefit of potential corrective strategies such as standardisation or simplification of a process or device • Manage the risk - evaluate and scope preventive and/or corrective strategies and then implement these, or place the problem on a risk register pending solution, or accept that what is needed is unaffordable • Communicate and consult - use interactive sessions, audit, on-going feedback, reminders and patient mediated prompts • Monitor and review the state of the problem - get baseline trends and patterns so that changes can be tracked and properly attributed to an intervention A hierarchy of levels of evidence has been proposed for clinical research and we argue that insufficient weighting has been given to lower ranked levels of research and to qualitative research, although critical interpretive synthesis is now gaining acceptance in mainstream thinking (e.g. by the Cochrane Collaboration). Fundamental challenges remain including how to grasp the elusive concept of patient safety, how to quantify, characterise and cost the problems, how to judge the extent to which harm can be attributed to errors, violations or system failures, how to identify contributing factors and the extent to which they can be implicated, how to judge whether incidents or their precursors are preventable, how to generate strong evidence to make healthcare safer and how to translate research into practice. Future directions include addressing the mundane as well as rare, dramatic events, and developing further research in non-hospital settings and in developing countries. In summary, a mixture of qualitative and quantitative methods, using information from all available data sources and combining retrospective, real time and prospective study designs, is necessary to address some of the more difficult patient safety problems.

Evidence of risk aversion in laboratory settings over small stakes leads to a priori implausible levels of risk aversion over large stakes under certain assumptions. One core assumption in statements of this calibration puzzle is that small-stakes risk aversion is observed over all levels of wealth, or over a â sufficiently largeâ range of wealth. Although this assumption is viewed as self-evident from the vast experimental literature showing risk aversion over laboratory stakes, it actually requires that lab wealth be varied (...) for a given subject as one evaluates the risk attitudes of the subject. We consider evidence from a simple design that tests this assumption, and find that the assumption is strikingly rejected for a large sample of subjects from a population of college students. We conclude that the implausible predictions that flow from these assumptions do not apply to one specialized population widely used to study economic behavior in laboratory experiments. (shrink)

According to color subjectivism, colors are mental properties, processes, or events of visual experiences of color. I first lay out an argument for subjectivism founded on claims from visual science and show that it also relies on a philosophical assumption. I then argue that subjectivism is untenable because this view cannot provide a plausible account of color perception. I describe three versions of subjectivism, each of which combines subjectivism with a theory of perception, namely sense datum theory, adverbialism, and the (...) virtual color proposal, and argue that each version faces serious objections. Considering these three theories of perception to be exhaustive of those available to the subjectivist, I conclude that subjectivism is untenable and that the scientifically motivated argument for this view is unsound. I then offer the diagnosis that the philosophical assumption on which this argument relies is mistaken. (shrink)

Martine Nida-Rümelin (1996) argues that color science indicates behaviorally undetectable spectrum inversion is possible and raises this possibility as an objection to functionalist accounts of visual states of color. I show that her argument does not rest solely on color science, but also on a philosophically controversial assumption, namely, that visual states of color supervene on physiological states. However, this assumption, on the part of philosophers or vision scientists, has the effect of simply ruling out certain versions of functionalism. While (...) Nida-Rümelin is quite right to search for empirical tests for claims about the nature of visual states, philosophical issues remain pivotal in determining the correctness of these claims. (shrink)

I argue that phenomenal externalism is preferable to phenomenal internalism on the basis of externalism's explanatory power with respect to qualitative character. I argue that external qualities, namely, external physical properties that are qualitative independent of consciousness, are necessary to explain qualitative character, and that phenomenal externalism is best understood as accepting external qualities while phenomenal internalism is best understood as rejecting them. I build support for the claim that external qualities are necessary to explain qualitative character on the basis (...) of a model of color perception as a certain sort of information filter by which perceivers gain access to external qualities.

There has been some recent optimism that addressing the question of how we distinguish sensory modalities will help us consider whether there are limits on a scientific understanding of perceptual states. For example, Block has suggested that the way we distinguish sensory modalities indicates that perceptual states have qualia which at least resist scientific characterization. At another extreme, Keeley argues that our common-sense way of distinguishing the senses in terms of qualitative properties is misguided, and offers a scientific eliminativism about (...) common-sense modalities which avoids appeal to qualitative properties altogether. I’ll argue contrary to Keeley that qualitative properties are necessary for distinguishing senses, and contrary to Block that our common-sense distinction doesn’t indicate that perceptual states have qualia. A non-qualitative characterization of perceptual states isn’t needed to avoid the potential limit on scientific understanding imposed by qualia. (shrink)

The problem of the nature of color is typically put in terms of the following question about the intentional content of visual experiences: what’s the nature of the property we attribute to physical objects in virtue of our visual experiences of color? This problem has proven to be tenacious largely because it’s not clear what the constraints are for an answer. With no clarity about constraints, the proposed solutions range widely, the most common dividing into subjectivist views which hold that (...) attributed colors are mental properties or mental events} and a variety of realist views, which hold that colors are properties of physical objects. These realist views, in turn, divide into views that hold that attributed colors are dispositions of physical objects to produce color experiences (dispositionalism),° nondispositional relations between objects and perceivers (the relational view)," physical properties of physical objects (physicalism),‘ or sui generis properties of physical objects (primitivism and impressionism).‘ I’ll examine a proposed constraint which Mark Johnston (1992) calls Revelation. According to Revelation, the appearance of color in our ordinary visual experience provides us with unqualified access to the nature of color. While every proposal about the nature of color must take a stand on how the.. (shrink)

I propose a strategy for a metaphysical reduction of perceived color, that is, an identification of perceived color with properties characterizable in non-qualitative terms. According to this strategy, a description of visual experience of color, which incorporates a description of the appearance of color, is a reference-fixing description. This strategy both takes color appearance seriously in its primary epistemic role and avoids rendering color as metaphysically mysterious. I’ll also argue that given this strategy, a plausible account of perceived color claims (...) that colors are physical properties of physical objects. (shrink)

C. L. Hardin led a recent development in the philosophical literature on color in which research from visual science is used to argue that colors are not properties of physical objects, but rather are mental processes. I defend J. J. C. Smart's physicalism, which claims that colors are physical properties of objects, against this attack. Assuming that every object has a single veridical (that is, nonillusory) color, it seems that physicalism must give a specification of veridical color in terms natural (...) to physics, independently of our interests. Hardin argues that since physicalism doesn't give us any such specification of veridical color, this view is false. However, this argument assumes a mistaken account of veridical color. I show physicalism can appeal to an alternative account, according to which veridical color is characterized in terms of favored conditions of perceptual access, independently of any specification of the physical nature of color.

I examine a dispute about the nature of practical reason, and in particular moral reason, generated by Thomas Nagel's proposal of an internalist rationalism which claims we can explain motivation in terms of reason and belief alone. In opposition, Humeans contend that such explanations must also appeal to further desires. Arguments on either side of this debate typically assume that a rationalist or Humean conclusion can be reached independently of a claim about the nature of moral judgment. I'll maintain, to (...) the contrary, that a resolution of this dispute can only be achieved on the basis of such a claim. (shrink)

With the success of cognitive science's interdisciplinary approach to studying the mind, many theorists have taken up the strategy of appealing to science to address long standing disputes about metaphysics and the mind. In a recent case in point, philosophers and psychologists, including Robert Kane, Daniel C. Dennett, and Daniel M. Wegner, are exploring how science can be brought to bear on the debate about the problem of free will. I attempt to clarify the current debate by considering how empirical (...) research can be useful. I argue that empirical findings don't apply to one basic dimension of the problem, namely the dispute between compatibilism and incompatibilism. However, I show that empirical research can provide constraints in connection with another fundamental dimension, namely the dispute between libertarianism, which claims that indeterminacy is, in certain contexts, sufficient for freedom, and hard determinism and compatibilism, which deny this. I argue that the source of the most powerful constraint is psychological research into the accuracy of introspection. (shrink)

This chapter examines the spectrum inversion hypothesis as an argument against certain kinds of account of what it’s like to be conscious of color. The hypothesis aims to provide a counterexample to accounts of what it’s like to be conscious of color in non-qualitative terms, as well as to accounts of what it’s like to be conscious of color in terms of the representational content of conscious visual states (which, according to some philosophers, is in turn given an account in (...) non-qualitative terms). I explain the hypothesis’s reasoning in sections 1 and 2. I then take up background issues: since the counterexample provided by the hypothesis is typically given as a possibility rather than an actuality, I briefly discuss the kind of possibility involved in section 3, and the methodologies used to evaluate the plausibility of possibilities in section 4. In section 5, I describe some general considerations that are commonly used against the spectrum inversion hypothesis. I take up attempts to support the hypothesis with findings from color science in section 6. I end with comments skeptical of both the motivation for the spectrum inversion hypothesis and the methodology used to support it. (shrink)

I take issue with Saunders & van Brakel's claim that neural processes play no interesting role in determining color categorizations. I distinguish an aspect of color categorization, namely, color discrimination, from other aspects. The law of trichromacy describes conditions under which physical properties cannot be discriminated in terms of color. Trichromacy is explained by properties of neural processes.

I examine the metaphysical issue of the nature of color. I argue that there are two distinct ranges of colors, namely, physical colors, which are disjunctive monadic physical properties of physical objects, and mental colors, which are properties of neural processes. ;A pair of claims provide the motivation for subjectivist and dispositionalist proposals about the nature of color, proposals which I reject. The first claim holds that a description of colors according to our ordinary experience of color provides a specification (...) of some aspects of the nature of color. The second holds that our ordinary experience of color provides access to the nature of color. ;In chapter 1, I argue that visual experiences have mental colors, neural properties which importantly determine our color categories. However, I reject C. L. Hardin's and James A. McGilvray's arguments for the subjectivist claim that the colors we attribute to physical objects are mental colors. ;In chapter 2, I show that Paul A. Boghossian and J. David Velleman's arguments in support of subjectivism rely on the assumption that visual experience provides unqualified access to the nature of color. I argue, however, that objections to their projectivism about color perception provide strong reasons to reject subjectivism as well as their assumption that visual experience provides unqualified access to the nature of color. ;In chapters 3 and 4, I examine Mark Johnston's and Christopher Peacocke's dispositionalist proposals about the nature of physical colors, which are founded on the claim that ordinary visual experience provides access to an aspect of the nature of color. I undercut dispositionalism by rejecting their arguments for the claim that ordinary visual experience provides such access. ;In chapter 5, I show that Evan Thompson's proposal that the colors of objects are relations between properties of perceivers and objects assumes that a description of color according to our ordinary experience specifies some aspects of the nature of color. I reject this assumption by distinguishing between mental color and physical color. I conclude that rather than specifying the nature of color, descriptions of colors according to our ordinary experience merely serve to fix the reference of color terms. (shrink)

In this paper I chart the seismic shift that has occurred over the past three decades in attitudes towards the interpretation of visual images. My strategy implies the argument that the reading of visual images would appear to be an inevitability given the accelerating change of attitudes towards pictures as containers of determinate knowledge. French critical theorists (Foucault, Barthes, Derrida et. al.) dominated debate on interpretation of text and image in the 1980s, where my survey begins. Michel Foucault dismissed the (...) image (in Madness and Civilization 1959/1988) as a fascinating site for the madness of dreams but one standing outside of reasoned interpretation because of an inherent excess of meaning and deeply hidden attributes and allusions. Generally, however, when images were discussed using identifiable interpretive strategies in the 1980s the framework was a variant of semiotic analysis (Marin, Eco and Barthes – who famously, diverges from this mode in Camera Lucida). I use W. J. T. Mitchell’s Iconology: Image, Text, Ideology 1986 as a focal text from the 1980s and follow this with two of his publications on images, one from 1995 and another from 2005 to demonstrate the dramatic shift in the approach to pictures across almost three decades. Around these focal texts by Mitchell I reference other texts and trends that culminate in the more recent proliferation of texts related to visual studies and the re-emergence of aesthetics.

Central to W.E.B. Du Bois’s political theory is a conception of “world” remarkably similar to that put forward, years later, by Martin Heidegger. This point is more methodological than historical: I claim that approaching Du Bois’s work as a source, rather than as a product, of concepts that resonated with subsequent thinkers allows us to better appreciate the novelty and vision of his political theory. Exploring this resonance, I argue, helps to refine the notions of world and founding present in (...) each theorist’s work. Yet, it is only by remaining attentive to their differences that we can understand how Du Bois and Heidegger could endorse such dramatically opposed political programs despite similar theoretical starting points.

This research systematically evaluates via prototype analysis how conceptualizations of Western adult's monotheistic God are structured. Over 4 studies, using U.S. student and community samples of predominantly Christians, features of God are identified, feature centrality is documented, and centrality influence on cognition is evaluated. Studies 1 and 2 produced considerable overlap in feature frequency and centrality ratings across the samples, with “God is love” being the most frequently listed central feature. In Studies 3 (choice latency) and 4 (recall and recognition (...) memory), the centrality of features influenced cognitive processes: central features were more quickly identified as features of God than peripheral features; were correctly recognized more often; and central features were correctly recalled more often than peripheral features. Results indicated that participants meaningfully judged centrality and that centrality affected cognition. Thus, the two criteria necessary for demonstrating deity representations adhere to a prototype structure were met. Implications and future directions are discussed. (shrink)

The Right and the Good, a classic of twentieth-century philosophy by the eminent scholar Sir David Ross, is now presented in a new edition with a substantial introduction by Philip Stratton-Lake, a leading expert on Ross.

Intuitionism is now enjoying a considerable revival, and Stratton-Lake provides the context for a proper understanding (...) of Ross's great work today. (shrink)

This paper examines the interrelations between astronomical images of nebulae and their observation. In particular, using the case of the ‘Great Spiral’ , we follow this nebula beginning with its discovery and first sketch made by the third Earl of Rosse in 1845, to giving an account, using archival sources, of exactly how other images of the same object were produced over the years and stabilized within the record books of the Rosse project. It will be found that a particular (...) ‘procedure’ was employed using ‘working images’ that interacted with descriptions, other images and the telescopic object itself. This stabilized not only some set of standard images of the object, but also a very potent conception of spirality as well, i.e. as a ‘normal form’. Finally, two cases will be contrasted, one being George Bond's application of this spiral conception to the nebula in Orion, and the other Wilhelm Tempel's rejection of the spiral form in M51.

One of the biggest challenges facing modern societies is how to monitor one’s intelligence community while maintaining the necessary level of secrecy. Indeed, while some secrecy is needed for mission success, too much has allowed significant abuse. Moreover, extending this secrecy to democratic oversight actors only creates another layer of unobserved actors and removes the public scrutiny that keeps their power and decision-making in check. This article will therefore argue for a new type of oversight through a specialised ethical whistleblowing (...) framework. This includes, first, outlining what intelligence wrongdoings justify whistleblowing; second, whether whistleblowing is the correct remedy – something not necessarily clear with intelligence; and finally, what form the whistleblowing should take. This framework will examine the Snowden case to determine whether he was correct leaking intelligence data and whether the means were appropriate, and second, whether those involved in the Central Intelligence...

The surge in threats aided by or carried out through cyberspace has placed significant pressure on the intelligence community to adapt or leave itself open to attack. Indeed, many in both political and intelligence circles argue for access to ever greater amounts of cyber information in order to catch potential threats before they become real. By collecting all our digital information, the intelligence community argues that it is not only able to detail what people have done or are currently doing (...) but also predict what their next move might be. However, the ethical implications are unclear and the backlash following Edward Snowden’s revelations have shown that such activities are not without controversy. This leaves the debate stuck between the important, ethical role that intelligence can play and the potential for its unrestrained use to cause undue harm. This paper will resolve this by giving greater detail to cyber-intelligence practices, highlighting the different levels of harm that the various intelligence operations can cause. The essence of this paper is not that cyber-intelligence should be banned outright, but that it can be justified given the necessary circumstances. Therefore, the paper will develop a specialised set of Just Cyber-Intelligence Principles, built on the just war tradition, to outline if and when such activities are justified. (shrink)

Anonymising technologies are cyber-tools that protect people from online surveillance, hiding who they are, what information they have stored and what websites they are looking at. Whether it is anonymising online activity through ‘TOR’ and its onion routing, 256-bit encryption on communications sent or smart phone auto-deletes, the user’s identity and activity is protected from the watchful eyes of the intelligence community. This represents a clear challenge to intelligence actors as it prevents them access to information that many would argue (...) plays a vital part in locating and preventing threats from being realised. Moreover, such technology offers more than ordinary information protections as it erects ‘warrant-proof’ spaces, technological black boxes that no matter what some authority might deem as being legitimately searchable is protected to the extent that there are very limited or non-existent means of forcing oneself in. However, it will be argued here that not only is using such anonymising technology and its extra layer of protection people’s right, but that it is ethically mandatory. That is, due to the en masse surveillance—from both governments and corporations—coupled with people’s limited awareness and ability to comprehend such data collections, anonymising technology should be built into the fabric of cyberspace to provide a minimal set of protections over people’s information, and in doing so force the intelligence community to develop more targeted forms of data collection.

Some arguments include imperative clauses. For example: ‘Buy me a drink; you can’t buy me that drink unless you go to the bar; so, go to the bar!’ How should we build a logic that predicts which of these arguments are good? Because imperatives aren’t truth apt and so don’t stand in relations of truth preservation, this technical question gives rise to a foundational one: What would be the subject matter of this logic? I argue that declaratives are used to (...) produce beliefs, imperatives are used to produce intentions, and beliefs and intentions are subject to rational requirements. An argument will strike us as valid when anyone whose mental state satisfies the premises is rationally required to satisfy the conclusion. For example, the above argument reflects the principle that it is irrational not to intend what one takes to be the necessary means to one’s intended ends. I argue that all intuitively good patterns of imperative inference can be explained using off-the-shelf formulations of our rational requirements. I then develop a formal-semantic theory embodying this view that predicts a range of data, including free-choice effects and Ross’s paradox. The resulting theory shows one way that our aspirations to rational agency can be discerned in the patterns of our speech, and is a case study in how the philosophy of language and the philosophy of action can be mutually illuminating.

The ethical value of intelligence lies in its crucial role in safeguarding individuals from harm by detecting, locating, and preventing threats. As part of this undertaking, intelligence can include protecting the economic well-being of the political community and its people. Intelligence, however, also entails causing people harm when it violates their vital interests through its operations. The challenge, therefore, is how to reconcile this tension, which Cécile Fabre's recent book Spying through a Glass Darkly does by arguing for the “ongoing (...) and preemptive imposition of defensive harm.” Fabre applies this underlying argument to the specifics of economic espionage to argue that while states, businesses, and individuals do have a general right over their information that prevents others from accessing it, such protections can be forfeited or overridden when there is a potential threat to the fundamental rights of third parties. This essay argues, however, that Fabre's discussion on economic espionage overlooks important additional proportionality and discrimination concerns that need to be accounted for. In addition to the privacy violations it causes, economic espionage can cause harms to people's other vital interests, including their physical and mental well-being and autonomy. Given the complex way in which the economy interlinks with people's lives and society, harms to one economic actor will have repercussions on those secondary economic entities dependent on them, such as workers, buyers, and investors. This, in turn, can produce further harms on other economic actors, causing damages to ripple outward across society. (shrink)
