We have lost one of the giants of the twentieth century physics when Yoichiro Nambu passed away in July, 2015, at the age of 94. Today's Standard Model, though still incomplete in many respects, is the culmination of the most successful theory of the Universe to date, and it is built upon foundations provided by discoveries made by Nambu in the 1960s: the mechanism of spontaneously broken symmetry in Nature (with G Jona-Lasinio) and the hidden new SU(3) symmetry (...) of quarks and gluons (with M-Y Han). In this volume honoring Nambu's memory, World Scientific Publishing presents a unique collection of papers written by his former colleagues, collaborating researchers and former students and associates, not only citing Nambu's great contributions in physics but also many personal and private reminiscences, some never told before. This book is a volume for all who benefited not only from Nambu's contributions toward understanding the Universe but also his warm and kind persona. It is a great addition to the history of contemporary physics. (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)

Medical paternalism has long been a common medical practice. However, patient autonomy in healthcare has been recently adopted by doctors and patients alike. This study explored whether doctors and patients in a tertiary care hospital in Saudi Arabia preferred autonomy or paternalism in shared decision‐making. A total of 118 participants (51 patients requiring total knee replacement, owing to stages 3–4 of osteoarthritis, and 67 doctors) from the Eastern province, Saudi Arabia. responded to a 17‐question category‐based questionnaire involving four scales of (...) autonomy. Descriptive statistics and chi‐square test results revealed that in this hospital, patients preferred a paternalistic approach toward their medical care along with a full disclosure of the risks related to surgical procedures. We recommend health education regarding the specific autonomy subscales (doctor knows best, patient should decide, right to non‐participation, and obligatory risk information), and the implementation of protocols that protect patients' rights and enhance personal autonomy.

Two thought experiments are discussed which suggest, first, a geometric interpretation of the concept of a (say, vector) potential (i.e., as a kinematic quantity associated with a transformation between moving frames of reference suitably related to the problem) and, second, that, in a quantum treatment one should extend the notion of the equivalence principle to include not only the equivalence of inertial forces with suitable “real” forces, but also the equivalence of potentials of such inertial forces and the potentials of (...) suitable real forces. The two types of cancellation are physically independent of each other, because of the Aharonov-Bohm effect. Finally, we show that the latter effect itself can be understood “geometrically” as a kinematic effect arising upon the transformation between the two reference frames. (shrink)

Abstract:The increasing needs for housing in Ghana is a result of urbanisation which is also a sign of improvement in the socio-economic lives of the people. Building of houses usually replaces prime vegetation land. The rate of indiscriminate devegetation for housing purpose in Ghana is as a result of the lack of a comprehensive land use policy implementation in the country. It is clearly stated in the country's land use policy that ‘the principle of optimum usage for all types of (...) land uses will be assured by the state and that, the state will ensure every socioeconomic activity is consistent with sound land use through sustainable land use planning in the long-term. But, evidence in the country is contrary to what is stipulated in the land use policy document. The study therefore, contributes to the environment-spatial land use conflict debate. It does this by focusing on the fast rate at which agricultural land at the fringes of urban Ghana is mainly used for housing purposes. It uses Accra and Tamale as examples to argue that if the content of the land use policy is not implemented to minimise the excessive devegetation for housing, the country stands the chance of losing utterly, its natural vegetation, especially, the forest vegetation. With the help of old maps, GIS and researchers’ observations, the study describes how the land use cover in areas close to the cities of Accra and Tamale has largely been replaced by housing. It ends by advocating sound sustainable housing typologies which will reduce the rate of devegetation in the country. (shrink)

Upshot: In the model simulation and the human experiment, we observed that attention shifted from a tool to a task. This was accompanied by bodily extension. However, our experiments lack a sense of bodily incorporation (the sense of ownership. Based on the valuable commentaries, we would like to discuss the necessary conditions for possible bodily incorporation in terms of redundant degrees of freedom, synchronous visual tactile stimulation, and 1/f noise.

We interpret the (formal) postulates of measurement in quantum theory in terms of measurement procedures that can be done in the laboratory (at least in principle).

How do we ready ourselves to intervene responsively in the contingent situations that arise in co-designing to make change? How do we attune to group dynamics and respond ethically to unpredictable developments when working with 'community'? Participatory Design can contribute to social transitions, yet its focus is often tightly tuned to technique for designing ICT at the cost of participatory practice. We challenge PD conventions by addressing what happens as we step into a situation to alter it with others, an (...) aspect of practice that cannot be replicated or interchanged. We do so to argue that practices of readiness are constituted by personal histories, experiences, philosophies and culture. We demonstrate this political argument by giving reflexive accounts of our dimensions of preparation. The narratives here are distinct, yet reveal complementary theories and worldviews that shape PD ontologies. We have organized these around the qualities of punctuation and poise as a way to draw out some less easily articulated aspects of PD practice. (shrink)

Open peer commentary on the article “Consciousness as Self-Description in Differences” by Diana Gasparyan. Upshot: Gasparyan’s article ignores the inherent tension of being a human who is both a subject and an object at the same time. Any theory of consciousness must include both of these dimensions.

The paper advances a Humean metaethical analysis of "intrinsic value" - a notion fundamental in moral philosophy in general and particularly so in environmental ethics. The analysis reduces an object's moral properties (e.g., its value) to the empirical relations between the object's natural properties and people's psychological dispositions to respond to them. Moral properties turn out to be both objective and subjective, but in ways compatible with, and complementary to, each other. Next, the paper investigates whether the Humean analysis can (...) support non-anthropocentric environmental ethical theories, which attribute intrinsic value to nonhuman natural entities. It argues that one of the most useful resources from Hume for non-anthropocentrism is his account of justice as an artificial virtue, which is a plausible model for the internalization of various environmentally friendly conventions and the creation of environmental values. Finally, the paper concludes that any Humean account of intrinsic value is empiricist all the way down. Moral questions about what things are intrinsically valuable, and to what extent they are so, are ultimately empirical questions about complex psychological capacities and dispositions of human beings, which cannot be single-handedly answered by philosophers a priori; and that ethics is more appropriately seen as an interdisciplinary investigation, requiring collaboration among the various psychological and social sciences, human biological and neurological sciences, and history and philosophy.
