PURPOSE: The offer to return research results to participants is increasingly recognized as an ethical obligation, although few researchers routinely return results. We examined the needs and attitudes of parents of children with cancer and of adolescents with cancer to the return of research results. METHODS: Seven experts in research ethics scored content validity on parent and adolescent questionnaires previously developed through focus group and phone interviews. The questionnaires were revised and provided to 30 parents and 10 adolescents in a (...) tertiary care oncology setting. RESULTS: The content validity index for individual questions and the overall questionnaires scored as 0.86 for both questionnaires. All 30 parents and 10 adolescents who agreed to participate returned questionnaires. The majority (>95%) indicated that they had a strong or very strong right to receive results. Letter or e-mail was a satisfactory means to return results described as good or neutral (66% parents, 100% adolescents) but more participants wished face-to-face disclosure of results with negative implications (50% parents, 60% adolescents). Very few wanted results disseminated through a Web site. The majority acknowledged the need for peer-review before disclosure (60% of adolescents and parents) but did not want "to be the last to know." CONCLUSIONS: Our data suggest that pediatric oncology patients and parents of children with cancer strongly feel that they have a right to research results, and that they wish to receive these in a timely manner.

It is often assumed that graphemes are a crucial level of orthographic representation above letters. Current connectionist models of reading, however, do not address how the mapping from letters to graphemes is learned. One major challenge for computational modeling is therefore developing a model that learns this mapping and can assign the graphemes to linguistically meaningful categories such as the onset, vowel, and coda of a syllable. Here, we present a model that learns to do this in English for strings (...) of any letter length and any number of syllables. The model is evaluated on error rates and further validated on the results of a behavioral experiment designed to examine ambiguities in the processing of graphemes. The results show that the model (a) chooses graphemes from letter strings with a high level of accuracy, even when trained on only a small portion of the English lexicon; (b) chooses a similar set of graphemes as people do in situations where different graphemes can potentially be selected; (c) predicts orthographic effects on segmentation which are found in human data; and (d) can be readily integrated into a full-blown model of multi-syllabic reading aloud such as CDP++ (Perry, Ziegler, & Zorzi, 2010). Altogether, these results suggest that the model provides a plausible hypothesis for the kind of computations that underlie the use of graphemes in skilled reading. (shrink)

Chow attacks statistical power analysis on theoretical grounds. I argue that if significance testing is defensible, so is power analysis. A number of Chow's criticisms seem to suggest that power analysts are confused about certain fundamental issues. I claim that few power analysts make the mistakes Chow describes. Finally, I address Chow's claim that power analysis is irrelevant to NHSTP because it deals with a different issue.

This paper provides a methodological analysis of Libertarian Paternalism, as put forward in the book Nudge by Richard Thaler and Cass Sunstein (Yale University Press, 2008). Libertarian Paternalism aims to use the accumulated findings of behavioural economics in order to assist decision-makers to make better choices. The philosophical debate about this proposal has focused on normative issues with regards to this proposal. This paper analyses Libertarian Paternalism descriptively and points out four methodological conditions for successful Nudges. On that basis, a (...) methodological critique of Libertarian Paternalism is mounted: the success conditions suggest that Nudges might be even harder to implement and to justify than commonly assumed in the philosophical debate.

The widespread use of stimulants among healthy individuals to improve cognition has received growing attention; however, public attitudes toward this practice are not well understood. We determined the effect of framing metaphors and context of use on public opinion toward cognitive enhancement. We recruited 3,727 participants from the United States to complete three surveys using Amazon’s Mechanical Turk between April and July 2017. Participants read vignettes describing an individual using cognitive enhancement, varying framing metaphors (fuel versus steroid), and context of (...) use (athletes versus students versus employees). The main outcome measure was the difference in respondent-assigned level of acceptability of the use of cognitive enhancement by others and by themselves between the contrasting vignettes. Participants were more likely to support the use of cognitive enhancement by others than by themselves and more when the use of enhancement by others was framed with a fuel metaphor than with a steroid metaphor. Metaphoric framing did not affect participants’ attitudes toward their own use. Participants supported the use of enhancement by employees more than by students or athletes. These results are discussed in relation to existing ethical and policy literature. (shrink)

We confront the philosophical literature on fair division problems with axiomatic and game-theoretic work in economics. Firstly, we show that the proportionality method advocated in Curtis is not implied by a general principle of fairness, and that the proportional rule cannot be explicated axiomatically from that very principle. Secondly, we suggest that Broome’s notion of claims is too restrictive and that game-theoretic approaches can rectify this shortcoming. More generally, we argue that axiomatic and game-theoretic work in economics is an indispensable (...) ingredient of any theorizing about fair division problems and allocative justice. (shrink)

On the received view, the Representational Theory of Measurement reduces measurement to the numerical representation of empirical relations. This account of measurement has been widely criticized. In this article, I provide a new interpretation of the Representational Theory of Measurement that sidesteps these debates. I propose to view the Representational Theory of Measurement as a library of theorems that investigate the numerical representability of qualitative relations. Such theorems are useful tools for concept formation that, in turn, is one crucial aspect (...) of measurement for a broad range of cases in linguistics, rational choice, metaphysics, and the social sciences.

This is a book about moral reasoning: how we actually reason and how we ought to reason. It defends a form of 'rule' utilitarianism whereby we must sometimes judge and act in moral questions in accordance with generally accepted rules, so long as the existence of those rules is justified by the good they bring about. The author opposes the currently more fashionable view that it is always right for the individual to do that which produces the most good. Among (...) the salient topics covered are: an account of the utilitarian function in society of generally accepted moral rules; a discussion of how we interpret existing moral rules and create new ones; and a defence of 'rule' utilitarianism against the charge that it either commits one to irrational rule worship, or collapses into a form of 'act' utilitarianism. This is a book about moral reasoning: how we actually reason and how we ought to reason. It defends a form of 'rule' utilitarianism whereby we must sometimes judge and act in moral questions in accordance with generally accepted rules, so long as the existence of those rules is justified by the good they bring about.

Controversies about time discounting loom large in decisions about climate change. Prominently, a particularly controversial debate about time discounting in climate change decision-making has been conducted within climate economics, between the authors of Stern et al. and their critics :977–981, 2006; Weitzman in J Econ Lit XLV:703–724, 2007; Nordhaus in J Econ Lit XLV:686–702, 2007). The article examines the role of values in this debate. Firstly, it is shown that time discounting is a case in which values are key because (...) it is at heart an ethical problem. Secondly, it is argued that time discounting in climate economics is a case of economists making frequent and routine references to ethical values and indeed conduct ethical debates with each other. Thirdly, it is argued that there is evidence for deep and pervasive entanglement between facts and values in the prevalent methodologies for time discounting. Finally, it is argued that this means that economists have given up the ‘value-free ideal’ concerning time discounting, and discussed how the current methodology of time discounting in economics can be improved.

In economics, the concept of time discounting introduces weights on future goods to make these less valuable. Yet, both the conceptual motivation for time discounting and its specic functional form remain contested. To address these problems, this paper provides a measurement-theoretic framework of representation for time discounting. The representation theorem characterises time discounting factors by representations of time dierences. This general result can be interpreted with existing theories of time discounting to clarify their formal and conceptual assumptions. It also provides (...) a conceptually neutral framework for comparing the descriptive and normative merits of those theories. (shrink)

This is the first translation into English of early phenomenologist Hedwig Conrad-Martius’ Metaphysical Conversations, originally published in 1921. Conrad-Martius was one of Husserl’s first students, an important part of the Göttingen Phenomenology Circle and mentor to Edith Stein, Jean Héring, and other early phenomenologists. The present volume provides the full German and English texts of the conversations, a phenomenological discussion of the nature of the human, examining the nature of body, soul, and spirit, and drawing distinctions between plants, (...) animals, humans, and various other beings. The volume also includes two important essays on phenomenology, in which Conrad-Martius distinguishes between the phenomenological approaches of Husserl, Heidegger, and the more ontological approach of the Göttingen school of phenomenology. She is critical of Husserl’s "transcendental" and Heidegger’s "existential" approach. The conversations illustrate her use of the phenomenological method for fundamental investigations into the nature (or Wesen) of things. (shrink)
