A case is made for supposing that the total probability accounted for in a decision analysis is less than unity. This is done by constructing a measure on the set of all codes for computable functions in such a way that the measure of every effectively accountable subset is bounded by a number <1. The consistency of these measures with the Savage axioms for rational preference is established. Implications for applied decision theory are outlined.

The current research investigates a combination of two instructional approaches, tutored problem solving and worked examples. Tutored problem solving with automated tutors has proven to be an effective instructional method. Worked‐out examples have been shown to be an effective complement to untutored problem solving, but it is largely unknown whether they are an effective complement to tutored problem solving. Further, while computer‐based learning environments offer the possibility of adaptively transitioning from examples to problems while tailoring to an individual learner, the (...) effectiveness of such machine‐adapted example fading is largely unstudied. To address these research questions, one lab and one classroom experiment were conducted. Both studies compared a standard Cognitive Tutor with two example‐enhanced Cognitive Tutors, in which the fading of worked‐out examples occurred either in a fixed way or adaptively. Results indicate that the adaptive fading of worked‐out examples leads to higher transfer performance on delayed posttests than the other two methods. (shrink)

The debate about positive and negative claims of conscience is, in large part, about ethical consistency. In this commentary I argue that there can be differences between conscientious provision of treatment and conscientious nonprovision of treatment that are ethically relevant. However, in many cases, including those described in this commentary, there is not sufficient ethical reason to treat them differently. This means that asymmetrical conscientious objection policies are potentially unjustified.

I intend to defend the following as a necessary condition of a belief S being epistemically justified for a subject:Awareness Requirement: S is justified in believing that P only if i) there is something, X, that contributes to the justification of B; and ii) S is aware of X.This will be shown through drawing attention to our considered judgments about cases. That will then lay the groundwork for giving an account of the nature of this awareness in the second half (...) of this paper. In doing so I will examine and respond to an argument against the awareness requirement that we might call Bergmann‟s Dilemma. My solution invokes what I call “non-doxastic strong awareness” in a way that avoids the regresses that Bergmann advances. (shrink)

In this commentary I assess the possible harms to a fetus with trisomy 18 of continued life. I argue that, although there is good reason to avoid subjecting infants to major surgery and prolonged intensive care where there is little chance of benefit, doctors should support and engage honestly with parents who decide to continue their pregnancies. We should ensure that infants with trisomy 18 have access to high quality palliative care.

In this essay I contrast Freud’s account of mourning in Mourning and Melancholia to that of Merleau-Ponty in Phenomenology of Perception. In suggesting a somatic as well as a psychic response, Merleau-Ponty, I argue, more accurately accounts for the ways in which we experience loss and why, contrary to Freud’s suggestion, mourning’s work is never completed.

This commentary is intended to illuminate Gold's & Stoljar 's main contentions by exploiting a favorite comparison, namely, that between biology and electronics. Roughly, and leaving out Darwinian theory and the like, biology is physics and chemistry plus natural history just as electronics is physics plus wiring diagrams. Natural history contains generalizations, not laws. Psychology and cognitive science typically give more abstract explanations, as do “block diagrams” in electronics, and are less dispensable.
