What aspects of the data from studies of acquired category- specific impairments are relevant to theories of knowledge representation? Discussion in the target article focuses on the living/nonliving dichotomy. However, many case studies reveal considerably more complex patterns of impaired and preserved performance that undermine this distinction. We consider this evidence and discuss its implications for theories of knowledge representation.

The Compactness Theorem The compactness theorem is a fundamental theorem for the model theory of classical propositional and first-order logic. As well as having importance in several areas of mathematics, such as algebra and combinatorics, it also helps to pinpoint the strength of these logics, which are the standard ones used in mathematics and arguably … Continue reading Compactness Theorem →.

Every healthcare organisation enacts a multitude of policies, but there has been no discussion as to what procedural and substantive requirements a policy writing process should meet in order to achieve good outcomes and to possess sufficient authority for those who are asked to follow it.Using, as an example, the controversy about patient’s refusal of blood transfusions, I argue that a hospital wide policy is preferable to individual decision making, because it ensures autonomy, quality, fairness, and efficiency.Policy writing for morally (...) controversial medical practices needs additional justification compared to policies on standard medical practices and secures legitimate authority for HCO members by meeting five requirements: all parties directed by the policy are represented; the deliberative process encompasses all of the HCO’s obligations; the rationales for the policy are made available; there is a mechanism for criticising, and for evaluating the policy.

The quantitative problem of old evidence is the problem of how to measure the degree to which e confirms h for agent A at time t when A regards e as justified at t. Existing attempts to solve this problem have applied the e-difference approach, which compares A's probability for h at t with what probability A would assign h if A did not regard e as justified at t. The quantitative problem has been widely regarded as unsolvable primarily on (...) the grounds that the e-difference approach suffers from intractable problems. Various philosophers have proposed that 'Bayesianism' should be rejected as a research strategy in confirmation theory in part because of the unsolvability of this problem. I develop a version of the e-difference approach which overcomes these problems and possesses various advantages (but also certain limitations). I develop an alternative 'theistic' approach which handles many cases that my development of the e-difference approach does not handle. I conclude with an assessment of the significance of the quantitative problem for Bayesianism and argue that this problem is misunderstood in so far as it is regarded as unsolvable, and in so far as it is regarded as a problem only for Bayesians.

Most authors who work with moral status automatically dismiss the possibility that plants are the kinds of entities that have moral status. This dismissal coheres with our intuitions about common-sense morality: if plants do not have moral status then we do not have any direct moral obligations to plant life. An implication of such a view is that any suggestion otherwise commits one to be in favour of an absurd conclusion. However, given the recent literature and empirical evidence on plant (...) minds, there are reasons to accept a different perspective that finds the absurd conclusion plausible. (shrink)

The healthcare crisis that has developed in the last two decades during China's economic reform has caused healthcare and hospital financing reforms to be largely experienced by patients as a crisis in the patient–healthcare professional relationship (PPR) at the bedside. The nature and magnitude of this crisis were epitomized by the "Harbin Scandal"—an incident that took place in August 2005 in a Harbin teaching hospital in which the family of an elderly patient hospitalized in the intensive care unit (ICU) for (...) 66 days paid over RMB ¥6 million. The news was publicized globally and ended in the firing of six top hospital administrators including the hospital president and the ICU director. This paper seeks to show that the Chinese healthcare crisis is ultimately linked to a conflict of interests between patients and healthcare professionals (HCPs), which is inherent in the reformed healthcare system of China. Hence the crisis is, at its core, a crisis of fidelity and confidence that must be restored to the PPR. At the "macro" level, it is simplistic to blame the crisis on the failure of the market system, and at the "micro" level, it is naïve to expect that a contractual understanding of the PPR will effectively restore the confidence of patients. This paper will show that the fiduciary relationship and medical professionalism share similar attributes, with fidelity being the core value of both. It concludes that the loss of medical fidelity implies the dissolution of the PPR and the demise of the medical profession and challenges Chinese HCPs to keep their fidelity as a means to both protect their patients’ interests and to preserve their profession's survival.
