We propose an efficient algorithm for deciding the reachability between any nodes on XML data represented by connected directed graphs. We develop a technique to reduce the size of the reference table for the reachability test. Using the small table and the standard range labeling method for rooted ordered trees, we show that our algorithm answers almost queries in a constant time preserving the space efficiency and a reasonable preprocessing time.

This chapter focuses on the use of effortless attention in performing daily activities and tasks. It details a study developed by The University of Chicago and Claremont Graduate University, and named the Experience Sampling Method to collect data from subjects of the study investigating the use of effortless attention in daily life. The findings are based on an ESM study of subjects consisting of middle and high school students from around the United States and the Sloan Study of Youth and (...) Social Development. The Sloan study focuses on investigating both effortful and effortless attention experiences of the subjects. A large number of students reveal how effortless attention has helped them to focus better on several tasks without much effort. (shrink)

The essay is a written version of a talk Nakamura Yūjirō gave at the College international de philosophie in Paris in 1983. In the talk Nakamura connects the issue of common sense in his own work to that of place in Nishida Kitarō and the creative imagination in Miki Kiyoshi. He presents this connection between the notions of common sense, imagination, and place as constituting one important thread in contemporary Japanese philosophy. He begins by discussing the significance of (...) place (basho) that is being rediscovered today in response to the shortcomings of the modern Western paradigm, and discusses it in its various senses, such as ontological ground or substratum, the body, symbolic space, and linguistic or discursive topos in ancient rhetoric. He then relates this issue to the philosophy of place Nishida developed in the late 1920s, and after providing an explication of Nishida’s theory, discusses it further in light of some linguistic and psychological theories. Nakamura goes on to discuss his own interest in the notion of common sense traceable to Aristotle and its connection to the rhetorical concept of topos, and Miki’s development of the notion of the imagination in the 1930s in response to Nishida’s theory. And in doing so he ties all three—common sense, place, and imagination—together as suggestive of an alternative to the modern Cartesian standpoint of the rational subject that has constituted the traditional paradigm of the modern West.

Free will in intentional consciousness is exposed to skeptics since it was found that subconscious neural activities, what is called readiness potential, precedes the intention to an action. The question of whether free will is an authentic illusion has been argued not only in psychology but physics and philosophy. Most of scientists, however, think that the intentional consciousness who believes to have his/her own free will, is determined by readiness potential in advance, and that free will cannot coexist with determinism. (...) We here point out that knowing to be determined in advance cannot be verified till local event at a local site can be known from a different local site without disturbing the event. That is the assumption of locality. We here show that determinism, free will and locality are three essential elements in consciousness, and show that they constitute trilemma. The fact that one of three elements must be abandoned can lead to three types of consciousness. Absence of free will can constitute type I consciousness which is consistent with symptoms in autism spectrum disorder such as weakened theory of mind. Absence of determinism can constitute type II consciousness which is consistent with symptoms in schizophrenia such as thought insertion, self-other integration. Absence of locality can constitute type III consciousness which is consistent with typical people. We can find the entanglement of intentional consciousness with unconsciousness including readiness potential only in type III consciousness. Finally, we show that sense of agency and free will cannot be established until consciousness as an entanglement is implemented. (shrink)

Transvertebral magnetic stimulation (TVMS) of the human lumbar spinal cord can evoke bilateral rhythmic leg movements, as in walking, supposedly through the activation of spinal locomotor neural circuitry. However, an appropriate stimulus intensity that can effectively drive the human spinal locomotor circuitry to evoke walking-like movements has not been determined. To address this issue, TVMS was delivered over an intervertebral space of the lumbar cord (L1–L3) at different stimulus intensities (10–70% of maximum stimulator output) in healthy human adults. In a (...) stimulus intensity-dependent manner, TVMS evoked two major patterns of rhythmic leg movements in which the left-right movement cycles were coordinated with different phase relationships: hopping-like movements, in which both legs moved in the same direction in phase, and walking-like movements, in which both legs moved alternatively in anti-phase; uncategorized movements were also observed which could not be categorized as either movement type. Even at the same stimulation site, the stimulus-evoked rhythmic movements changed from hopping-like movements to walking-like movements as stimulus intensity was increased. Different leg muscle activation patterns were engaged in the induction of the hopping- and walking-like movements. The magnitude of the evoked hopping- and walking-like movements was positively correlated with stimulus intensity. The human spinal neural circuitry required a higher intensity of magnetic stimulation to produce walking-like leg movements than to produce hopping-like movements. These results suggest that TVMS activates distinct neural modules in the human spinal cord to generate hopping- and walking-like movements. (shrink)

Given the known hazards of nuclear energy in seismically active Japan after the Fukushima meltdowns as well as the presence of viable conservation and renewable energy options, the question of Japan’s stalled energy transition warrants critical interrogation. To better understand why, after Fukushima, Japan’s energy policy trajectory maintained the nuclear status quo and an increased reliance on fossil fuels, this article employs network and historical analyses to examine the confluence of post-Fukushima political forces connected to Japan’s nuclear energy sector. Our (...) novel network dataset combines with historical analysis to identify a dense network of overlapping executives and officials in Japan that forge long-term ties between the nuclear energy industry, the state, and the leading business federation in Japan. Following the 3.11 disaster and the meltdowns at the Fukushima-Daiichi facility, a long-standing nuclear safety myth and a tightly networked nuclear energy industrial complex provided an ideological and structural context to re-legitimize nuclear energy in spite of widespread public concern. Instead of a bold, ecologically rational policy to quickly phase out nuclear power and phase in renewable energy, well-worn class and state networks aligned to recommit Japan to a nuclear-reliant energy path. These findings support a theoretical synthesis around our concept of an energy industrial complex with applications in environmental and political sociology. (shrink)

In this paper, I attempt to elucidate Husserl’s later phenomenological approach to the unconscious as a limit problem of phenomenology. Husserl had encountered the kind of problem as the unconscious earlier on and it continued to come up throughout his work. There are references to the unconscious in Ideas II and in the Analyses Concerning Passive Synthesis, and even in early lectures. Nonetheless, the unconscious as a severe problem of Husserl’s phenomenology emerged only in his mature phase. In this paper, (...) I first discuss how Husserl treats the unconscious in relation to affection in Analyses Concerning Passive Synthesis, in order to shed light on the process of how the unconscious is problematized in phenomenology. Then, I rely on his later manuscripts on the unconscious in Husserliana XLII, where Husserl deals with the unconscious in relation to waking and sleeping. At the end, I explain how Husserl explores the multi-layered structure of consciousness as a result of his treatment of the unconscious as limit problem of phenomenology. (shrink)

Although advance care planning can lead to more patient-centered care, the communication around it can be challenging in acute care hospitals, where saving a life or shortening hospitalization is important priorities. Our qualitative study in an acute care hospital in Japan revealed when specifically physicians and nurses start communication to facilitate ACP. Seven physicians and 19 nurses responded to an interview request, explaining when ACP communication was initiated with 32 patients aged 65 or older. Our qualitative approach employed descriptive analysis (...) to identify major themes, which included “initiation by patients” and “initiation by healthcare professionals.” In the latter case, seven specific triggers were identified: when the patients’ medical condition changed in terms of symptom relief, when the patients’ medical condition changed in terms of prognostic prediction, when serious events occurred, when a choice of treatment was presented, when the location for end-of-life care was chosen, when the patients’ cognitive function deteriorated, and when serious events settled down. Within this group of healthcare professionals, physicians were more focused on changes in their patients’ medical condition, whereas nurses focused more on their patients’ desire for a long-term perspective. Nurses encouraged patients to consider ACP themselves, which developed into an approach to respect patients’ autonomy. In acute care hospitals, it appeared to be desirable to have an early discussion where patients could understand the significance ACP, which would matter even after their discharge from the hospital.

LetL be any modal or tense logic with the finite model property. For eachm, definer L (m) to be the smallest numberr such that for any formulaA withm modal operators,A is provable inL if and only ifA is valid in everyL-model with at mostr worlds. Thus, the functionr L determines the size of refutation Kripke models forL. In this paper, we will give an estimation ofr L (m) for some linear modal and tense logicsL.

As interpersonal, racial, social, and international conflicts intensify in the world, it is important to safeguard the mental health of individuals affected by them. According to a Buddhist notion “if you want others to be happy, practice compassion; if you want to be happy, practice compassion,” compassion practice is an intervention to cultivate conflict-proof well-being. Here, compassion practice refers to a form of concentrated meditation wherein a practitioner attunes to friend, enemy, and someone in between, thinking, “I’m going to help (...) them.” The compassion meditation is based on Buddhist philosophy that mental suffering is rooted in conceptual thoughts that give rise to generic mental images of self and others and subsequent biases to preserve one’s egoism, blocking the ultimate nature of mind. To contextualize compassion meditation scientifically, we adopted a Bayesian active inference framework to incorporate relevant Buddhist concepts, including mind, compassion, aggregates, suffering, reification, conceptual thoughts, and superimposition. In this framework, a person is considered a Bayesian Engine that actively constructs phenomena based on the aggregates of forms, sensations, discriminations, actions, and consciousness. When the person embodies rigid beliefs about self and others’ identities and the resulting ego-preserving bias, the person’s Bayesian Engine malfunctions, failing to use prediction errors to update prior beliefs. To counter this problem, after recognizing the causes of sufferings, a practitioner of the compassion meditation aims to attune to all others equally, friends and enemies alike, suspend identity-based conceptual thoughts, and eventually let go of any identity-grasping belief and ego-preserving bias that obscure reality. We present a brain model for the Bayesian Engine of three components: Relation-Modeling, Reality-Checking, and Conflict-Alarming, which are subserved by the Default-Mode Network, Frontoparietal Network and Ventral Attention Network, and Salience Network, respectively. Upon perceiving conflicts, the strengthening or weakening of ego-preserving bias will critically depend on whether the SN up-regulates the DMN or FPN/VAN, respectively. We propose that compassion meditation can strengthen brain regions that are conducive for suspending prior beliefs and enhancing the attunements to the counterparts in conflicts. (shrink)

Pain is an important focus for consciousness research because it is an avenue for exploring somatic awareness, emotion, and the genesis of subjectivity. In principle, pain is awareness of tissue trauma, but pain can occur in the absence of identifiable injury, and sometimes substantive tissue injury produces no pain. The purpose of this paper is to help bridge pain research and consciousness studies. It reviews the basic sensory neurophysiology associated with tissue injury, including transduction, transmission, modulation, and central representation. In (...) addition, it highlights the central mechanisms for the emotional aspects of pain, demonstrating the physiological link between tissue trauma and mechanisms of emotional arousal. Finally, we discuss several current issues in the field of pain research that bear on central issues in consciousness studies, such as sickness and sense of self. (shrink)

The facial expression of pain is the end product of a complex process that is, in part, emotional. The evolutionary study of facial expression must account for the social nature of human consciousness and should address the questions of why empathy exists, the adaptive importance of empathy, and whether facial expression is a mechanism of empathy and second-person consciousness.
