We clarify the significance of quasiprobability in quantum mechanics that is relevant in describing physical quantities associated with a transition process. Our basic quantity is Aharonov’s weak value, from which the QP can be defined up to a certain ambiguity parameterized by a complex number. Unlike the conventional probability, the QP allows us to treat two noncommuting observables consistently, and this is utilized to embed the QP in Bohmian mechanics such that its equivalence to quantum mechanics becomes more transparent. We (...) also show that, with the help of the QP, Bohmian mechanics can be recognized as an ontological model with a certain type of contextuality. (shrink)

Zen Training is a comprehensive handbook for zazen , seated meditation practice, and an authoritative presentation of the Zen path. The book marked a turning point in Zen literature in its critical reevaluation of the enlightenment experience, which the author believes has often been emphasized at the expense of other important aspects of Zen training. In addition, Zen Training goes beyond the first flashes of enlightenment to explore how one lives as well as trains in Zen. The author also draws (...) many significant parallels between Zen and Western philosophy and psychology, comparing traditional Zen concepts with the theories of being and cognition of such thinkers as Heidegger and Husserl.

We examined whether children's ability to integrate speech and gesture follows the pattern of a broader developmental shift between 3- and 5-year-old children regarding the ability to process two pieces of information simultaneously. In Experiment 1, 3-year-olds, 5-year-olds, and adults were presented with either an iconic gesture or a spoken sentence or a combination of the two on a computer screen, and they were instructed to select a photograph that best matched the message. The 3-year-olds did not integrate information in (...) speech and gesture, but 5-year-olds and adults did. In Experiment 2, 3-year-old children were presented with the same speech and gesture as in Experiment 1 that were produced live by an experimenter. When presented live, 3-year-olds could integrate speech and gesture. We concluded that development of the integration ability is a part of the broader developmental shift; however, live-presentation facilitates the nascent integration ability in 3-year-olds. (shrink)

フェミニズムの歴史とは、「私たちとは誰なのか」を批判的に問うてきた歴史でもある。フェミニストとして語るあなたとは誰なのか。その語りはどんな場所からなされているのか。その語りからは誰が排除されているのか 。「私たちが共にあること」はいかにして可能なのか。フェミニズムはもちろん一枚岩ではない。それでも、私にとってのフェミニズムとは、自己の、そして他者の“トラブル”に直面しながらその声に応答しようとしてき たフェミニズムである。ジュディス・バトラーの『ジェンダー・トラブル』と、田中美津の「とり乱し」を架橋する、理論と実践の両面からの試み。.

In social contexts, people are responsible for their actions and outcomes. Diffusion of responsibility is a well-known social phenomenon: people feel less responsible when performing an action with co-actors than when acting alone. In previous studies, co-actors reduced the participant’s responsibility attribution by making the cause of the outcomes ambiguous. Meanwhile, it is unclear whether the presence of co-actors creates diffusion of responsibility even in situations where it is “obvious” that both oneself and the co-actor are the causes of an (...) outcome. To investigate this potential diffusion of responsibility, we used a temporal binding task as a measure of causal attribution. Low TB effects indicate the enhancement of external attribution in perceptual processing for the action and outcomes. To investigate the influence of presence of a co-actor on causal attribution, participants were required to act under two experimental conditions: an ALONE condition or a TOGETHER condition. The only difference between the two conditions was whether the actions were shared. In addition, to make participants feel responsible, they were induced to feel guilt. In the High-harm condition, participants gave a financial reduction to a third party. When guilt was induced, participants showed lower TB effects in the TOGETHER condition compared to the ALONE condition. Our study suggests that actions with a co-actor change causal attributions even though the causes of the outcome are obvious. This may have implications for understanding diffusion of responsibility in inhumane situations. (shrink)

The exocyst is a conserved octameric complex that physically tethers a vesicle to the plasma membrane, prior to membrane fusion. It is important not only for secretion and membrane delivery but also, in mammalian cells, for cytokinesis, ciliogenesis, autophagy, tumorigenesis, and host defense. The combination of genome editing and advanced light microscopy of exocyst subunits in living cells has recently shown the complex to be much more dynamic than previously appreciated, and exposed how little we still know about its function (...) and regulation.

The Millennium Development Goals were criticised for failing to address the issue of governance, and the associated notions of responsibility and accountability. The Sustainable Development Goals, we argue, need to recognise the structural constraints facing poor countries – the power imbalances in the global economic system that limit their ability to promote the prosperity and well-being of their people, as was clearly brought out by the Commission on Global Governance for Health, of which we were both members [Ottersen, O. P., (...) J. Dasgupta, C. Blouin, Paulo Buss, Virasakdi Chongsuvivatwong, Julio Frenk, Sakiko Fukuda-Parr, et al. 2014. “The Political Origins of Health Inequality: Prospects for Change.” Lancet 383: 630–667]. This article is divided into three parts. We begin by making the case for a global justice perspective which emphasises the responsibility – and hence also accountability – of international organisations and rule-making bodies. We next demonstrate the limitations of accountabi.. (shrink)

Children’s intentions should be respected. Parents are the key persons involved in decision-making related to their children. In Japan, the appropriate ages and standards for a child’s consent and assent, approval, and decision-making are not clearly defined, which makes the process of obtaining consent and assent for clinical research complex. The purpose of this paper is as follows: to understand the attitudes and motives of parents concerning children’s participation in medical research and the factors influencing their decision-making. We also sought (...) to clarify who has the right to be involved in decisions regarding children’s participation in research. A semi-structured Internet survey on parents’ opinions and attitudes and preferences concerning medical research involvement was conducted. Children were divided into three age groups (6–10-year-olds, 11–14-year-olds, and 15–18-year-olds), with three illness severity categories. Possible correlations between the number of children, children’s ages, parents’ educational levels, and parents’ attitudes were examined. Among the participants, 42.3% recognized the term “informed consent.” The proportion of participants who understood “informed consent” increased with educational level. Four out of five participants did not know, or had not heard of, the term “informed assent.” Furthermore, the percentage of those who understood the term “informed assent” increased with academic level. Participants generally believed in prioritizing parents’ opinions over children’s, and that parents and children would ideally reach a joint decision. Although many parents favored collaborative decision-making, they also wanted their own will reflected in the decision and felt they should receive important information before their children do. Decision-making was affected by the condition’s severity and prognosis. This indicates that most Japanese parents believe that their children have the right to know their disease name and treatment; nonetheless, they should be protected. Parents’ values and judgments regarding medical intervention involving their children varied. Children’s ability to consent to treatment and research believed to be in their best interests should be assessed appropriately. They should be permitted to provide consent or assent, and their views should be respected. Involving children in decision-making fosters more open communication and transparency between medical professionals, parents, and children. (shrink)

Mediator is a coregulatory complex that plays essential roles in multiple processes of transcription regulation. One of the human Mediator subunits, MED26, has a role in recruitment of the super elongation complex (SEC) to polyadenylated genes and little elongation complex (LEC) to non‐polyadenylated genes, including small nuclear RNAs (snRNAs) and replication‐dependent histone (RDH) genes. MED26‐containing Mediator plays a role in 3′ Pol II pausing at the proximal region of transcript end sites in RDH genes through recruitment of Cajal bodies (CBs) (...) to histone locus bodies (HLBs). This finding suggests that Mediator is involved in the association of CBs with HLBs to facilitate 3′ Pol II pausing and subsequent 3′‐end processing by supplying 3′‐end processing factors from CBs. Thus, we argue the possibility that Mediator is involved in the organization of nuclear bodies to orchestrate multiple processes of gene transcription. (shrink)

Contemplating one’s own death is a core aspect in the history of Western philosophy. In the modern era, existential philosophy has inherited this tradition and established unique discussions on the concept of “_my_ death,” resting on the premise that this concept is unapproachable via scientific inquiry. Conversely, biological research is essentially conducted within the scope of life phenomena, with death being referred to in the sense of lifespan; thus, death is not among its inherent themes, which automatically excludes the concept (...) of _my_ death from its scope. To establish a dialogue between the two fields, this study questions the widely held premise that _my_ death is unrelated to science and is best examined by philosophy. I consider the movement between continuity and discontinuity as foundational to scientific development, and integrate it with the relationship between the unknown and known. Furthermore, I extend this to the concepts of consciousness and body, and subsequently clarify and define the unknown divisions. Finally, I examine the kinds of unknowns that science confronts to interpret philosophically how an aspect of reproductive theory has unwittingly revealed a completely new dimension of life: _my_ death. Overall, I argue that _my_ death is an essential point of contact between philosophy and biology that reveals the scholarly significance of the unknown. (shrink)

The inositol phosphate metabolism network has been found to be much more complex than previously thought, as more and more inositol phosphates and their metabolizing enzymes have been discovered. Some of the inositol phosphates have been shown to have biological activities, but little is known about their signal transduction mechanisms except for that of inositol 1,4,5‐trisphosphate. The recent discovery, however, of a number of binding proteins for inositol high polyphosphate [inositol 1,3,4,5‐tetrakisphosphate (IP4), inositol 1,3,4,5,6‐pentakisphosphate, or inositol hexakisphosphate] enables us to (...) speculate on the physiological function of these compounds. In this article we focus on two major issues: (1) the roles of inositol high polyphosphates in vesicular trafficking, especially exocytosis, and (2) pleckstrin homology domaincontaining IP4 binding proteins involved in the Ras signaling pathway.

The capacity of visual working memory (VWM) refers to the amount of visual information that can be maintained in mind at once, readily accessible for ongoing tasks. In healthy young adults, the capacity limit of VWM corresponds to about three simple objects. While some researchers argued that VWM capacity becomes adult-like in early years of life, others claimed that the capacity of VWM continues to develop beyond middle childhood. Here we assessed whether VWM capacity reaches adult levels in adolescence. Using (...) an adaptation of the visual change detection task, we measured visual working memory capacity estimates in 13 year-olds, 16-year-olds, and young adults. We tested whether the capacity estimates observed in early or later years of adolescence were comparable to the estimates obtained from adults. Our results demonstrated that the capacity of VWM continues to develop throughout adolescence, not reaching adult levels even in 16 year-olds. These findings suggest that VWM capacity displays a prolonged development, similar to the protracted trajectories observed in various other aspects of cognition. (shrink)
