Healthcare-associated infections due to multidrug-resistant organisms continue to increase in incidence. To control the transmission of these pathogens, such as methicillin-resistant Staphylococcus aureus , some have advocated active surveillance cultures of all hospitalized patients, followed by institution of contact precautions. While there has been extensive debate about the effectiveness of this approach in reducing infections, little attention has been given to the ethical issues raised by the intervention. Active surveillance for multidrug-resistant organisms is a quality improvement measure and ethical implications (...) arise through the potential to inadvertently cause harm. Unintended adverse effects may include decreased contact with healthcare workers, increased depression and anxiety, and increased rates of noninfectious adverse events among patients placed in contact precautions. The potential risks and benefits are not distributed fairly; patients placed in contact precautions are exposed to the risks, while those not isolated experience the benefit. Ethical challenges involve a conflict between the interests of the individual patient and the patient population not already colonized with the organism. For healthcare systems, active surveillance increases the complexity of bed management, exacerbating problems with patient placement, patient throughput, emergency department overcrowding and ambulance diversion for some hospitals. It also poses ethical dilemmas regarding societal resource allocation. Investing in an unproven or marginally beneficial quality improvement activity such as this must be balanced against other public health priorities competing for scarce resources.

Using as a case study the forensic comparison of images for purposes of identification, this essay considers how the history, philosophy and sociology of science might help courts to improve their responses to scientific and technical forms of expert opinion evidence in ways that are more consistent with legal system goals and values. It places an emphasis on the need for more sophisticated models of science and expertise that are capable of helping judges to identify sufficiently reliable types of expert (...) evidence and to reflexively incorporate the weakness of trial safeguards and personnel into their admissibility decision making.

Thus far in the development of the discipline of medical ethics, the overriding concern has been with solutions to specific problems. But discussion is hampered by lack of understanding of the scope and methodology of medical ethics, and its scientific and philosophical basis. In Underpinnings of Medical Ethics Edmond A. Murphy, James J. Butzow, and Edward L. Suarez-Murias offer much-needed clarification of the purview, ontological basis, and methodology of a medical ethics that is to be comprehensive and yet readily (...) accepted by all. The authors begin by describing the scope of the analysis and discussing possible ethical systems and paradigms. They then deal with the structures and concepts necessary in the formulation of a coherent philosophy: normality and disease, scientific and juridical law, certainty and certitude, decisions. Finally, they introduce particular human dimensions, such as quality of life, pain, and responsibility. Throughout, case examples illustrate the authors' theoretical framework. (shrink)
In view of the excellent arguments that have been put forth recently in favour of qualia, internal sensory presentations, it would strike an impartial observer - one could imagine a future historian of philosophy - as extremely odd why so many philosophers who are opposed to qualia, that is, sensory experiences internal to the brain, have largely ignored those arguments in their own. There has been a fashionable assumption that any theory of perception which espouses qualia has long since been (...) overcome by a number of 'formidable' objections, in particular, the Homunculus/Infinite Regress Objection, the Solipsism Objection, Austin's Illusion/Delusion Objection, the Ludicrousness-of-Colours-in-the-Brain Objection, the Indirect-Realist-has-to-assume-Direct-Realism Objection, the Impossibility-of-Comparing-Internal-with-External Objection, the Impossibility of Intrinsic Experience, and several more minor varieties of these. It is uncanny how they continue to be repeated, indeed, with a kind of automatism, evidenced by the fact that none of those who repeat them appear to have taken note of the answers to the objections. Indeed, they only appear to refer to those philosophers with whom they agree: it has long been insisted upon in the study of rhetoric that one of the weakest things to do in an argument is to ignore the main points made by one's opponent:
[it is] the wisest plan _to state Objections in their full force_ ; at least, wherever there does exist a satisfactory answer to them; otherwise, those who hear them stated more strongly than by the uncandid advocate who had undertaken to repel them, will naturally enough conclude that they are unanswerable. It is but a momentary and ineffective triumph that can be obtained by man. (shrink)
A sensory receptor, in any organism anywhere, is sensitive through time to some distribution - energy, motion, molecular shape - indeed, anything that can produce an effect. The sensitivity is rarely direct: for example, it may track changes in relative variation rather than the absolute change of state (as when the skin responds to colder and hotter instead of to cold and hot as such); it may track differing variations under different conditions (the eyes' dark-adaptation; adaptation to sound frequencies can (...) lower the difference threshold; the kinesthetic sense will shut down if a limb is held in a stationary position too long - the limb 'going to sleep'); it may be subject to distortion of the input from overloading (dazzle producing strong-after-images); it may not be confined to one channel of sensitivity (the retina is sensitive to pressure; the hands can feel some strong sound-vibrations, the tympanum of the ear records touch). Strictly speaking there is no limit as to what intensities and what ranges receptors could be sensitive. Sharks are sensitive to electrostatic fields, homing pigeons to magnetic fields; snakes to infra-red rays; bacteria to acid concentrations; perhaps there has even been a mutant organism sensitive to the passage of cosmic rays, even though that would hardly have bestowed any conceivable survival value. What is irrefutable is that individual receptors differ markedly from organism to organism, between different members of the species (one dog being better at tracing smells than another; one person being able to sense light-waves of 375 nanometres, another not; children able to hear 20,000 Hz, older persons not), and between receptors of the same kind within one organism (one eye being sensitive to 765 nm and the other not; one ear deaf to 15,000 Hz and over, the other not). There are also just-noticeable-differences (JND's), in that one person can see two shades of a colour where another sees only one; similarly with sounds. (shrink)
It is the purpose of this article to explicate the logical implications of a television analogy for perception, first suggested by John R. Smythies (1956). It aims to show not only that one cannot escape the postulation of qualia that have an evolutionary purpose not accounted for within a strong functionalist theory, but also that it undermines other anti-representationalist arguments as well as some representationalist ones.

This discussion takes up an attack by Jerrold Aronson (seconded by Rom Harre) on the use made by Norwood R. Hanson of the Gestalt-Switch Analogy in the philosophy of science. Aronson's understanding of what is implied in a gestalt switch is shown to be flawed. In his endeavor to detach conceptual understanding from perceptual identification he cites several examples, without realizing the degree to which such gestalt switches can affect conceptualizing or how conceptualizing can affect gestalts. In particular, he has (...) not confronted the possibility of such gestalt selection being involved in the basic identification of what we term "entities". (shrink)
One evolutionary advantage is that, because of sensory and perceptual relativity (acknowledged as an empirical fact), the tracking of portions of the real relevant to the living creature can be enhanced if updating from species-member to species-member can take place. In human perception, the structure is therefore in the form of a triangulation (Davidson's metaphor) in which continual mutual correction can be performed. Language, that which distinguishes human beings from other animals, capitalizes on that structure. The means by which updating (...) of adaptiveness takes place in the human species is shown to involve a covert hypothesis of singularity in co-reference, a structure that brings the idea of mutual faith and its character to the fore.

This essay attempts to identify the ethical principles appropriate to a second-order political agent—an agent, that is, whose primary responsibility lies not in the implementation of state power, but in the response to and evaluation of that state power. The specific agent I examine is the human rights non-governmental organization, and the specific context is that of humanitarian military intervention. I argue that the specific role of the human rights NGO gives rise to ethical permissions not available to government agents. (...) In particular, such NGOs may have permissions to ignore the motivation of government agents, and support even substantially unjust interventions, where such interventions would have substantial benefit for the defense and preservation of basic human rights. a Footnotesa Previous versions of this paper were presented at Brown University, the Edmond J.

Freud's Jokes and their Relation to the Unconscious (1976 [1905]), because of its subject-matter, has had a fragmented history. From within psychoanalysis itself it has been regarded as an early application of the insights of his dream theory to a by-way of human behaviour, in which the unconscious adopts techniques against the censor similar to those that are operative within the dream. In his essay 'Humour' (1985 [1927]) Freud himself did later add an addendum on humour per se which related (...) it to his id-ego-superego topology, extending the context of relevance to the operations of the superego as an 'heir to the parental agency', but he did not widen the generality of his explanation further.

The originator of the notion of structural isomorphism was the philosopher Roy Wood Sellars. Many modern philosophers are unaware how this notion vitiates their attacks on the concept of an internal sensory presentation. His view that this allowed for corrective feedback undercuts Palmer's belief that there is a mapping of objects. The privacy of subjective experience is also shown not to be inviolable.
Steven Lehar allows too much to his direct realist opponent in using the word “subjective” of the sensory field per se. The latter retains its nonconceptual, nonmental nature even when explored by perceptual judgement. He also needs to stress the evolutionary value of perceptual differences between person and person, a move that enables one to undermine the direct realist's superstitious certainty about the singular object.
In this paper I shall try to analyse appropriate logic and actual methods as a preliminary to developing expert systems that will simulate clinical diagnosis. It is doubtful that all diagnoses address the same kind of problem and hence no one logic will suffice. Sometimes the signs and symptoms manifest an underlying disorder that cannot be observed directly (the substantialist model); sometimes there seems to be no underlying disorder and the diagnosis is a rearrangement of the data (the nominalist model). (...) In deciding their merits in the particular case, we must identify the sources of variation; what is meant by saying that the data are independent; and what can be meant by wrong diagnosis and misclassification. Problems arise in human diagnosis because the data may be false, even lies; because the known list of diseases is not exhaustive; and because the probability of multiple unrelated diseases increases with age. Special difficulties arise from homeostasis (which is fundamental in defining and understanding disease) because the primary disturbances may be hard to distinguish from the homeostatic responses to them.

The authors are working with a limited notion of religion. They have confined themselves to a view of it as superstition, “counterintuitive,” as they put it. What they have not seen is that faith does in a real sense involve a paradox in that it projects an impossibility as a methodological device, a fictive ploy, which in the best interpretation necessarily involves a commitment to the likelihood of self-sacrifice.
The formal properties of orbits in a plane are explored by elementary topology. The notions developed from first principles include: convex and polygonal orbits; convexity; orientation, winding number and interior; convex and star-shaped regions. It is shown that an orbit that is convex with respect to each of its interior points bounds a convex region. Also, an orbit that is convex with respect to a fixed point bounds a star-shaped region.Biological considerations that directed interest to these patterns are indicated, and (...) the implications of the prospect of higher orders of star-shapedness mentioned.

Zenon Pylyshyn here repeats the same error as in his original article (1973) in starting with the premiss that all cognition is a matter of perceiving entities already given in their singularity. He therefore fails to acknowledge the force of the evolutionary argument that perceiving is a motivated process working upon a non-epistemic sensory registration internal to the brain.
Interesting as the experiments are, their relevance to the real-life situation is rendered questionable by the unthinking use of given singularities as target objects. The evolutionary process does not respect what one agent takes to be a singular referent. A “singling” from the continuum is rather a varying feature of the necessity to track what is rewarding in it.
The epistemology and ontology of experimentation are discussed in depth with special reference to biology and medicine. Two types of experiments are distinguished: exploratory (or "blazing") and consolidating. They Have objectives and canons that are strikingly different. A contrast is drawn between the literalism of the most pragmatic scientists and the formalism of most statisticians. The terms and notions of the one may have imperfect correspondence with those of the other, or perhaps none at all. The dangers are pointed out (...) of both the conclusion that the gap between the two is unbridgeable and the contrary view that the gap is trivial and merits no serious attention. Substantive discussions address the choice and meaning of a metric, the idea of interaction and time series analysis, the ontology of variation, and the epistemology of randomization, hypothesis-seeking, and multiple comparisons. * From the Division of Medical Genetics, Johns Hopkins University School of Medicine, Baltimore Md. 21205.

The authors O'Regan & Noë (O&N) have ignored the case for the visual field as being non-epistemic evidence internal to the brain, having no pictorial similarity to the external input, and being material in ontological status. They are also not aware of the case for the evolutionary advantage of learning as the perceptual refashioning of such non-epistemic sensory evidence via motivated feedback in sensorimotor activity.
Arthur M. Glenberg omits discussion of motivation and this leads him to an underestimation of the part played by pleasure and pain and desire and fear in both the clamping and the updating of percepts. This commentary aims at rectifying this omission, showing that mutual correction plays an important role.

A system of semigroup identities is hereditarily finitely based if it defines a variety all semigroups of which are finitely based. Two new types of hereditarily finitely based identity systems are presented. Two of these systems, together with eight existing systems, establish the hereditary finite basis property of every semigroup of order five or less with one possible exception.
