I am interested in extending modal calculi by adding propositional quantifiers, given by the rules for quantifier introduction: provided that p does not occur free in A.

Prevalence of contract cheating and outsourcing through organised methods has received interest in research studies aiming to determine the most suitable strategies to reduce the problem. Few studies have presented an international approach or tested which variables could be correlated with contract cheating. As a result, strategies to reduce contract cheating may be founded on data from other countries, or demographics/situations which may not align to variables most strongly connected to engagement in outsourcing. This paper presents the results of a (...) series of statistical analyses aimed at testing which variables were found to be predictors of students’ self-reported formal outsourcing behaviours. The data are derived from an international research study conducted in 22 languages, with higher education students (from Europe, the Americas and Australasia. Analyses found that country and discipline of study as well as the rate at which respondents n = 7806) believed other students to be cheating, were positively correlated to their cheating behaviours. Demographic variables did not show strong statistical significance to predicting contract cheating. (shrink)

Deductive reasoning shares with other forms of thinking a reliance on strategies, as shown by the results of three experiments on the nature and development of control strategies to solve suppositional deductions. These puzzles are based on assertors who may or may not be telling the truth, and their assertions about their status as truthtellers and liars. The first experiment shows that reasoners make backward inferences as well as forward inferences, to short-cut their way through the alternatives, and the generation (...) of suppositions is a source of difficulty. The second experiment establishes that the elimination of the suppositional status of an individual does not render problems easier. The third experiment shows that reasoners can improve their reasoning accuracy and speed spontaneously, without feedback, and it clarifies the transfer of strategies and their development. We discuss the implications of these data for alternative theories of suppositional deduction and for the relationship between reasoning and other forms of thinking such as problem solving. (shrink)

This book focuses upon the perennial question of the existence and nature of an obligation to obey the law. Leading writers have, at one time or another, emphasized considerations such as gratitude, 'divine ordering, ' prudence, contract, autonomy, and utility in seeking to justify, or to deny any justification for, some sort of obligation to obey the positive law. The book provides relevant selections from a sampling of the historical approaches to legal obligation taken by writers such as Plato, Augustine, (...) Aquinas, Hobbes, Locke, Hume, Rousseau, Thoreau, Bentham, Marx and Engels, and Martin Luther King, Jr. These classical discussions are augmented by critical questions and commentary, by independent discussions of the question of legal obligation by a wide range of contemporary writers, and by relevant judicial cases discussing matters such as conscientious objection and civil disobedience.

Undergraduate medical ethics education currently focuses on ethical concepts and reasoning. This paper uses an intern’s story of an ethically challenging situation to argue that this emphasis is problematic in terms of ensuring students’ ethical practice as junior doctors. The story suggests that it is aligning their actions with the values that they reflectively embrace that can present difficulties for junior doctors working in the pressures of the hospital environment, rather than reasoning to an ethically appropriate action. I argue that (...) junior doctors need skills for implementing their ethical decisions and that these ought to form a central component of undergraduate medical ethics education. (shrink)

I answer Alvin Plantinga's challenge to provide a ‘proper’ de jure objection to religious belief. What I call the ‘sophisticates’ evidential objection' concludes that sophisticated Christians lack epistemic justification for believing central Christian propositions. The SEO utilizes a theory of epistemic justification in the spirit of the evidentialism of Richard Feldman and Earl Conee. I defend philosophical interest in the SEO against objections from Reformed epistemology, by addressing Plantinga's criteria for a proper de jure objection, his anti-evidentialist arguments, and the (...) relevance of ‘impulsional evidence’. I argue that no result from Plantinga-style Reformed epistemology precludes the reasons I offer in favour of giving the SEO its due philosophical attention. (shrink)

SummaryThis article examines the Scottish philosopher James Beattie's controversial work of moral philosophy An Essay on the Nature and Immutability of Truth, noted for its pugnacious attack on the sceptical philosophy of David Hume. Usually treated only as an ephemeral success in the early 1770s, the Essay actually had two distinct periods of enormous popularity that account for its contemporary significance in the period between 1770 and 1830. The prominence of the Essay is demonstrated by its widespread positive reception, evinced (...) in both published and private responses, in both England and Scotland, by the high estimation in which it was held within pedagogical circles as an anti-sceptical philosophical primer, and by its continual use as a textbook in both university and dissenting academy logic and moral philosophy classes. In these senses, Beattie's Essay was arguably the most significant work of the Common Sense School of Scottish philosophy. (shrink)

Much has been written on the genesis of the pseudo-hesiodic Shield of Heracles — so much, that true progress is difficult to discern among the welter of theories. But some has been made, although the conclusions that have been reached must be regarded as likely hypotheses rather than proven facts. In this article I propose to proceed from some of these conclusions, ensuring that they are as firmly grounded as possible, to an assessment of how this poem's version of the (...) combat of Heracles and Cycnus relates to the likely circumstances and occasion of its original performance. This will involve considering the legend's variants , and a new look at the first half of the Homeric Hymn to Pythian Apollo. (shrink)

A photoaffinity analog of cGMP has been used to biochemically identify a new ligand-binding subunit of the retinal rod cGMP-activated ion channel, as well as amino acids in contact with cGMP in the original subunit. Covalent tethering of this probe to channels in excised menbrane patches has revealed a functional heteogeneity in the ligand-binding sites that may arise from the two biochemically identified subunits.
