This Handbook documents the main trends in current research between logic and language, including its broader influence in computer science, linguistic theory and cognitive science. The history of the combined study of Logic and Linguistics goes back a long way, at least to the work of the scholastic philosophers in the Middle Ages. At the beginning of this century, the subject was revitalized through the pioneering efforts of Gottlob Frege, Bertrand Russell, and Polish philosophical logicians such as Kazimierz Ajdukiewicz. Around (...) 1970, the landmark achievements of Richard Montague established a junction between state-of-the-art mathematical logic and generative linguistic theory. Over the subsequent decades, this enterprise of Montague Grammar has flourished and diversified into a number of research programs with empirical and theoretical substance. This appears to be the first Handbook to bring logic-language interface to the fore. Both aspects of the interaction between logic and language are demonstrated in the book i.e. firstly, how logical systems are designed and modified in response to linguistic needs and secondly, how mathematical theory arises in this process and how it affects subsequent linguistic theory. The Handbook presents concise, impartial accounts of the topics covered. Where possible, an author and a commentator have cooperated to ensure the proper breadth and technical content of the papers. The Handbook is self-contained, and individual articles are of the highest quality. (shrink)

The formation of particles of elemental tin in association with the nucleation of the precipitate phase θ′ in an Al–1.7 at.% Cu–0.01 at.% Sn alloy has been investigated by high resolution transmission electron microscopy. Analysis of lattice images has demonstrated that these tin particles associated with θ′ platelets formed during short-term ageing (typically 3 min at 200 degrees Celcius) exhibit a crystallographic form that is distinctly different from that previously reported in such ternary alloys and also from that observed in (...) the binary alloy Al–0.01 at.% Sn. Those tin particles that could be clearly identified as β-Sn phase shared a crystallographic relationship of the form (001)Sn‖(001)Al‖(001)θ′, [110]Sn‖[100]Al‖[100]θ′ with the α-Al and θ′ phases with which they were simultaneously in contact. The observations imply that, while tin may assist nucleation of platelets of θ′, the formation of θ′ equally influences the crystallography of β--Sn that forms in association with θ′. Following prolonged ageing (typically 50 h at 200°C), the β-Sn particles in contact with θ′ plates had coarsened and diminished in number, and most now exhibited an orientation relationship with α-Al matrix similar to that observed in the binary alloy Al–0.01 at.% Sn (i.e. (100)Sn‖(111)Al, [010]Sn‖[112]Al) and to that previously observed in the later stages of ageing of the ternary alloy Al–1.7 at.% Cu–0.01 at.% Sn.

This study provides current data on key questions about retraction of scientific articles. Findings confirm that the rate of retractions remains low but is increasing. The most commonly cited reason for retraction was research error or inability to reproduce results; the rate from research misconduct is an underestimate, since some retractions necessitated by research misconduct were reported as being due to inability to reproduce. Retraction by parties other than authors is increasing, especially for research misconduct. Although retractions are on average (...) occurring sooner after publication than in the past, citation analysis shows that they are not being recognised by subsequent users of the work. Findings suggest that editors and institutional officials are taking more responsibility for correcting the scientific record but that reasons published in the retraction notice are not always reliable. More aggressive means of notification to the scientific community appear to be necessary. (shrink)

Betrachtet man den Gebrauch der Worte ‘Moral’ und ‘Vernunft’ etwas genauer, so stellt man fest, dass nicht klar ist, was sie bezeichnen bzw. wie Moral und Vernunft zusammenhängen. In dem Buch ‘Rationalität in der Angewandten Ethik’, in dem sich verschiedene Autoren die Aufgabe gestellt haben, diese Umstände in das Licht der Betrachtung zu rücken, finden wir Fragen darüber, wie “Moral”, “Angewandte Ethik” und “Vernunft” (auch in der Anwendung) zu verstehen und zu vereinen sind.

We formulate and analyze the dynamics of an influenza pandemic model with vaccination and treatment using two preventive scenarios: increase and decrease in vaccine uptake. Due to the seasonality of the influenza pandemic, the dynamics is studied in a finite time interval. We focus primarily on controlling the disease with a possible minimal cost and side effects using control theory which is therefore applied via the Pontryagin’s maximum principle, and it is observed that full treatment effort should be given while (...) increasing vaccination at the onset of the outbreak. Next, sensitivity analysis and simulations (using the fourth order Runge-Kutta scheme) are carried out in order to determine the relative importance of different factors responsible for disease transmission and prevalence. The most sensitive parameter of the various reproductive numbers apart from the death rate is the inflow rate, while the proportion of new recruits and the vaccine efficacy are the most sensitive parameters for the endemic equilibrium point.

Nicholas Wolterstorff's Divine Discourse attempts to give philosophical warrant to the claim that ‘God speaks’. While Wolterstorff's argument depends largely on his appropriation of J.L. Austin's speech act theory, he also uses two narratives that for him demonstrate how ‘God speaks’. The first is the story of Augustine's conversion in the Confessions and the second is a story that Wolterstorff recounts about a certain ‘Virginia’. This study argues that what Wolterstorff claims to derive from Augustine's narrative for his view of (...) divine discourse is not fully supported by the Confessions, and that Augustine's interpretation of the words ‘tolle lege, tolle lege’, can be construed as a useful interpretation of an ambiguous sign. This is consistent with Augustine's understanding of the interpretation of texts in both the De doctrina christiana and the Confessions. In short, Augustine is far more open to the ambiguity of signs than Wolterstorffs's account suggests. (shrink)

Iris Murdoch’s Metaphysics as a Guide to Morals ranges wide over the field of Western philosophical thought. Throughout the work, Murdoch proposes and enacts a form of philosophical inquiry that she believes supports a moral philosophy based on the idea of the good. One of her attempts, partly inspired by Paul Tillich and J. N. Findlay, centers on her critique and appropriation of the structure of the so-called “ontological argument” in Anselm’s Proslogion. This study assesses Murdoch’s accomplishment and the tenability (...) of the kind of Platonism she proposes against Anselm’s argument about the good in both the Monologion and the Proslogion. My claim is that Anselm’s conception of the good simply does not permit the kind of interpretation that Murdoch puts on the “ontological argument.”. (shrink)

Herein we examine the theory and practical limits of designing a voluntary incentive scheme to protect endangered species on private land. We consider both an ay-ante scheme, in which a contract to the landholder depends only on what the landholder reports, and an ay-post scheme, in which a contract to the landholder depends on reports from all landowners. Except in special cases, the ex-ante scheme never implements the full information allocation, and can actually set aside too much land. In contrast, (...) expected habitat size under the ex-post scheme is smaller than both the ex-ante and full information allocations. (C) 2001 Elsevier Science (USA). (shrink)
