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)

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)

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)

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.

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.

В статті досліджуються механізми виникнення концептосфери Інтернету «розумних» речей. Представлено розуміння процесів трансферу з ментального плану людини у простір культури концептів. Дослідження вказує на важливість еволюції ментального плану людини для процесів трансформації когнітивно перетворювальної практики людини. Такий феномен техніки, як ІРР, сформував нове ментальне середовище – концептосферу «ІРР», яка має важливе значення для формування ментального плану людини. Концептосфера «ІРР» має вплив у всіх сферах діяльності людини: науці, техніці, культурі, медицині, економіці, побуті тощо. Концептосфера «ІРР», як і сама техносфера ІРР, характеризується (...) аутопоезисом та автономністю. (shrink)

This study had two purposes: to explore the components of the pedagogical content knowledge (PCK) of an experienced elementary science teacher and to reveal the presumed interactions among these components. A naturalistic inquiry was conducted as a single case study in which in-depth qualitative data were gathered through semi-structured interview questions. After the theory-based and data-driven analysis of the qualitative data, the verbal communication was quantitated into numerical data for the enumerative analysis. The results revealed that the teacher’s knowledge of (...) students’ understanding and difficulties, knowledge of the elementary science curriculum and knowledge of instructional strategies and representations were found to be mostly intersected PCK components, whereas orientations towards teaching science and knowledge of assessment in science had limited connections to the other components. Further discussions and context-based suggestions are given regarding professional development programmes. (shrink)
