Nanometre-sized ! '-martensites , a few nanometres in cross-sectional diameter, formed at intersections of deformation twins, have been found in a heavily deformed 316-type austenitic stainless steel and examined by high-resolution transmission electron microscopy . An orientation relationship was found to be close to the Kurdjumov-Sachs relationship, that is , . HRTEM observations were conducted with a beam direction parallel to . The observed nanometre-sized ! '-martensites exhibited a habit plane and the cross-section of the nanometre-sized ! '-martensites were elongated (...) along [545] % . It has been revealed that the nanometre-sized ! '-martensites of a few nanometres diameter formed at the intersections of deformation twins have a typical habit plane of , which is identical with that reported for a fully grown plate such as ! '-martensite. The origin of the observed habit plane is discussed on the basis of the d 112 ¢ {111} ! shear displacements assisting the % M ! ' transformation. (shrink)

Using the corpus of JSTOR articles, we investigate the role of gender in collaboration patterns across the scholarly landscape by analyzing gender-based homophily--the tendency for researchers to co-author with individuals of the same gender. For a nuanced analysis of gender homophily, we develop methodology necessitated by the fact that the data comprises heterogeneous sub-disciplines and that not all authorships are exchangeable. In particular, we distinguish three components of gender homophily in collaborations: a structural component that is due to demographics and (...) non-gendered authorship norms of a scholarly community, a compositional component which is driven by varying gender representation across sub-disciplines, and a behavioral component which we define as the remainder of observed homophily after its structural and compositional components have been taken into account. Using minimal modeling assumptions, we measure and test for behavioral homophily. We find that significant behavioral homophily can be detected across the JSTOR corpus and show that this finding is robust to missing gender indicators in our data. In a secondary analysis, we show that the proportion of female representation in a field is positively associated with significant behavioral homophily. (shrink)

Foundational issues in statistical mechanics and the more general question of how probability is to be understood in the context of physical theories are both areas that have been neglected by philosophers of physics. This book fills an important gap in the literature by providing a most systematic study of how to interpret probabilistic assertions in the context of statistical mechanics. The book explores both subjectivist and objectivist accounts of probability, and takes full measure of work in the foundations of (...) probability theory, in statistical mechanics, and in mathematical theory. It will be of particular interest to philosophers of science, physicists and mathematicians interested in foundational issues, and also to historians of science. (shrink)

Contemporary bioethics is usually notable for its focus on the uses and abuses of biomedical technology, on personal liberty and the on the formulation of ethical problems as dilemmas to be solved by utilitarian calculus within the frameworks of committees and institutional guidelines. It is argued that these developments actually reflect a technologization of medical ethics itself, which more often relies non-personal algorithms of utility.This is explained, from a historical point of view, by the impact of technology on the concepts (...) of nature and naturalism and by the triumphs of modern science, which obscures non-scientific modes of discourse. The article acknowledges some benefits of the technologization of ethics such as the democratization of decision-making but the discussion concentrates on five arguments against the dominance of utilitarianism in medical ethics. The common denominator of these arguments is that utilitarianism fails its own standards by undermining trust in the public domain. The loss of trust is brought about by the displacement of the phenomenological self and from fostering adversarialism in ethical discourse. (shrink)

© Springer-Verlag Berlin Heidelberg 2015. When reasoning about knowledge of procedures under imperfect information, the explicit representation of epistemic possibilities blows up the S5like models of standard epistemic logic. To overcome this drawback, in this paper, we propose a new logical framework based on compact models without epistemic accessibility relations for reasoning about knowledge of procedures. Inspired by the 3-valued abstraction method in model checking, we introduce hyper models which encode the imperfect procedural information. We give a highly non-trivial 2-valued (...) semantics of epistemic dynamic logic on such models while validating all the usual S5 axioms. Our approach is suitable for applications where procedural information is ‘learned’ incrementally, as demonstrated by various examples. (shrink)
