The key mutation of the schizophrenic psyche can be described as a disturbance of the first person-ness of the I-sense, i.e., of the sense of the "I" as personal subject of experience and of action. Under these circumstances, representations of things are not definitively experienced as "my" representations—with the self-evidence of belonging to me. This uncertainty of selfhood, specific to schizophrenia, cannot be reduced to a disability of intellect, logic, judgment, or memory. In the course of developing his argument, the (...) author criticizes philosopher Michel Henry's critique of Heidegger's (1961) interpretation of Descartes's cogito ergo sum. (shrink)

Chef de file de la réflexion psychiatrique au Japon, le Professeur Kimura Bin s’oppose dans cet article aux réductionnismes physicalistes en découvrant au coeur de la subjectivité une articulation complexe entre le personnel et l’impersonnel qui simultanément confirme la conception spirituelle zen de la constitution de l’individualité et donne une base à la fondation d’une science psychiatrique véritable. Il démontre que l’orientation donnée par les sciences cognitives et la philosophie analytique conduit à ignorer la différence entre réalité et actualité, (...) et occulte ainsi le fait que chaque existant est unique, manquant de la sorte à la fois son unité et son unicité. Pour retrouver l’originalité propre à chacun, Kimura propose d’en retrouver l’originarité, esquissée dans le concept heideggérien de Befindlichkeit, et d’élargir la subjectivité au sens proposé par Victor von Weizsäcker en tant que rencontre avec le milieu. Il conclut cette étude phénoménologique en proposant de fonder une psychopathologie en première personne, c’est-à-dire d’introduire la subjectivité dans la science psychiatrique, seule voie pour comprendre l’existence et résoudre l’énigme de la schizophrénie.

For genetic algorithms, it is important to maintain the population diversity. Some genetic algorithms have been proposed, which have an ability to control the diversity. But these algorithms use the distance between two individuals to control the diversity. Therefore, these performances become worse on ill-scaled functions. In this paper, we propose a new genetic algorithm, DIDC(a genetic algorithm with Distance Independent Diversity Control), that does not use a distance to control the population diversity. For controlling the diversity, DIDC uses two (...) GAs that have different natures. For realizing different natures, one GA uses a crossover operator as a search operator, and the other GA uses a mutation operator in DIDC. By applying DIDC to several benchmark problems, we show that DIDC has a good performance on high dimensional, multimodal, non-separable and ill-scaled problems. Finally, we show that the control parameter of DIDC has the same effect on the search with the number of generating children n c. (shrink)

Many often say that people resemble their pets or that the faces of manga characters and Buddha statues resemble those of their artists. Previous studies demonstrated that participants could match dogs with their owners, suggesting that pets resemble their owners. Other studies also demonstrated that people can match personal belongings, including inanimate objects, to their owners. However, it is unknown whether people tend to make objects that resemble themselves. In this study, we examined whether people tend to make objects that (...) resemble themselves with dolls made of cloth as stimuli. The results demonstrated that people tend to project themselves into dolls, even in the case of amateur college students. The mere exposure effect or the algorithm “self seeks like” may be at play in not only people’s selection of pets but also their making of objects. (shrink)

Web-based learning resources provide learners with hyperspace where they can navigate in a self-directed way to learn the contents included in the Web pages. The navigation involves making a sequence of the pages visited, which is called navigation path. However, learners often fail in making the navigation path due to a cognitive overload, which is caused by diverse cognitive efforts at comprehending the contents in Web pages, and monitoring the navigation process such as planning and reflection of navigation path. In (...) the self-directed learning, in particular, it is difficult for learners to maintain the navigation monitoring. Focusing on navigation planning, this paper addresses the issue of how to facilitate learners' navigation monitoring to promote their learning in hyperspace provided by Web-based learning resources. Our approach to this issue is to provide learners with a space, in which they can see through the learning resources to plan a navigation path, apart from hyperspace. In this paper, we also demonstrate an assistant system for the navigation planning, which is composed of hyperspace map, page previewer, and path previewer. These facilities give learners an overview of Web pages and navigation path to help them make a navigation path plan without visiting Web pages in hyperspace. This paper also describes a case study with the assistant system. The results indicate that the system facilitates navigation particularly in a more complicated hyperspace. (shrink)

We propose simple nonlinear mathematical models for the legal concept of balancing of interests. Our aim is to bridge the gap between an abstract formalisation of a balancing decision while assuring consistency and ultimately legal certainty across cases. We focus on the conflict between the rights to privacy and to the protection of personal data in Art. 7 and Art. 8 of the EU Charter of Fundamental Rights (EUCh) against the right of access to information derived from Art. 11 EUCh. (...) These competing rights are denoted by ( \(i_1\) ) _right to privacy _ and ( \(i_2\) ) _access to information_; mathematically, their indices are respectively assigned by \(u_1\in [0,1]\) and \(u_2\in [0,1]\) subject to the constraint \(u_1+u_2=1\). This constraint allows us to use one single index _u_ to resolve the conflict through balancing. The outcome will be concluded by comparing the index _u_ with a prior given threshold \(u_0\). For simplicity, we assume that the balancing depends on only selected legal criteria such as the social status of affected person, and the sphere from which the information originated, which are represented as inputs of the models, called legal parameters. Additionally, we take “time” into consideration as a legal criterion, building on the European Court of Justice’s ruling on the right to be forgotten: by considering time as a legal parameter, we model how the outcome of the balancing changes over the passage of time. To catch the dependence of the outcome _u_ by these criteria as legal parameters, data were created by a fully-qualified lawyer. By comparison to other approaches based on machine learning, especially neural networks, this approach requires significantly less data. This might come at the price of higher abstraction and simplification, but also provides for higher transparency and explainability. Two mathematical models for _u_, a time-independent model and a time-dependent model, are proposed, that are fitted by using the data. (shrink)

In recent times, international comparative studies on managers’ beliefs regarding ethical/unethical leadership have increased in number. These studies focus on both Eastern and Western countries. However, although these previous studies focused on the effects of national culture, they did not pay sufficient attention to the effects of institutions. Moreover, these studies covered only a few countries. Despite Japan’s strong influence on the world economy, it has not been included in previous studies on ethical leadership. Thus, to reveal unexplored factors—particularly cultural (...) and institutional factors—and to determine the generalizability of previous findings, this study used a qualitative research method to examine Japanese business managers’ beliefs about ethical/unethical leadership. The data revealed the convergence and divergence in beliefs regarding ethical/unethical leadership between managers in Japan and in other countries. The analysis identified mostly the same themes of ethical/unethical leadership as found in other countries albeit with different distributions. In addition, We identified new themes that may be specific to Japan or that were neglected in previous studies. Moreover, this study suggests the necessity of considering each society’s history of business ethics and current ethics-related institutional contexts in ethical/unethical leadership studies.

Previous empirical studies have shown that perceptions of organizational politics are negatively related to individuals’ affective commitment. The key contribution of this study was that it found the interactive moderating effects of political skill and quality of leader–member exchange (LMX) on the relationship between perceptions of organizational politics and affective commitment. Our results indicated that politics perception affective commitment relationship was weaker when both political skill and quality of LMX are high. When only political skill is high and the quality (...) of LMX is low, or LMX quality is high but political skill is low, the negative relationship between politics perception and affective commitment was not mitigated. Limitations and implications for future research are discussed. (shrink)

Recently, some studies revealed that transcranial direct current stimulation reduces dual-task interference. Since there are countless combinations of dual-tasks, it remains unclear whether stable effects by tDCS can be observed on dual-task interference. An aim of the present study was to investigate whether the effects of tDCS on dual-task interference change depend on the dual-task content. We adopted two combinations of dual-tasks, i.e., a word task while performing a tandem task and a classic Stroop task while performing a tandem task. (...) We expected that the Stroop task would recruit the dorsolateral prefrontal cortex and require involvement of executive function to greater extent than the word task. Subsequently, we hypothesized that anodal tDCS over the DLPFC would improve executive function and result in more effective reduction of dual-task interference in the Stroop-tandem dual-task than in the word-tandem dual-task. Anodal or cathodal tDCS was applied over the DLPFC or the supplementary motor area using a constant current of 2.0 mA for 20 min. According to our results, dual-task interference and the task performances of each task under the single-task condition were not changed after applying any settings of tDCS. However, anodal tDCS over the left DLPFC significantly improved the word task performance immediately after tDCS under the dual-task condition. Our findings suggested that the effect of anodal tDCS over the left DLPFC varies on the task performance under the dual-task condition was changed depending on the dual-task content. (shrink)

Japan is unusual among industrialized countries in its reluctance to use brain criteria to determine death and harvest transplant organs. This results from public distrust of the medical profession due to an earlier incident, and from concern that technological interventions will threaten religious and cultural traditions surrounding death and dying. Public acceptance is growing, however, as medical professional groups and universities develop brain criteria, and as pressure from patients who could benefit from a transplant, as well as from foreign countries, (...) increases.

This study explored the relationship between professional quality of life and emotion work and the major stress factors related to abortion care in Japanese obstetric and gynecological nurses and midwives. Between October 2011 and January 2012, questionnaires that included questions concerning eight stress factors, the Professional Quality of Life Scale, and the Japanese version of the Frankfurt Emotional Work Scale, were answered by 255 nurses and midwives working in abortion and childbirth services. Professional Quality of Life scores (compassion fatigue, compassion (...) satisfaction, burnout) were significantly associated with stress factors and emotion work. Multiple regression analysis revealed that of all the evaluated variables, the Japanese version of the Frankfurt Emotional Work Scale score for negative emotions display was the most significant positive predictor of compassion fatigue and burnout. The stress factors “thinking that the aborted fetus deserved to live” and “difficulty in controlling emotions during abortion care” were associated with compassion fatigue. These findings indicate that providing abortion services is a highly distressing experience for nurses and midwives. (shrink)

Quantum walks exhibit different properties compared with classical random walks, most notably by linear spreading and localization. In the meantime, random walks that replicate quantum walks, which we refer to as quantum-walk-replicating random walks, have been studied in the literature where the eventual properties of QWRW coincide with those of QWs. However, we consider that the unique attributes of QWRWs have not been fully utilized in the former studies to obtain deeper or new insights into QWs. In this paper, we (...) highlight the directivity of one-dimensional discrete quantum walks via QWRWs. By exploiting the fact that QWRW allows trajectories of individual walkers to be considered, we first discuss the determination of future directions of QWRWs, through which the effect of linear spreading and localization is manifested in another way. Furthermore, the transition probabilities of QWRWs can also be visualized and show a highly complex shape, representing QWs in a novel way. Moreover, we discuss the first return time to the origin between RWs and QWs, which is made possible via the notion of QWRWs. We observe that the first return time statistics of QWs are quite different from RWs, caused by both the linear spreading and localization properties of QWs. (shrink)

The Bose-Einstein condensation of free relativistic particles [ε=(M 2 c 4 +c 2 p 2 ) 1/2 −Mc 2 ] is studied rigorously. For massless bosons (ε=cp), the condensation transition of third (second) order occurs in2 (3) dimensions (D). The molar heat capacity follows the T 2 (T 3 ) law below the condensation temperature Tc [k B Tc=(2πħ 2 c 2 n/1.645) 1/2 [(π 2 ħ 3 c 3 n/1.202) 1/3 ], reaches4.38 (10.8) R at T=Tc, and approaches the (...) high-temperature-limit value2 (3) R with no jump (a jump equal to6.75R) in2 (3)D. For finite-mass (M) bosons, the phase transition occurs only in3D with the condensation temperature Tc always smaller than that of the corresponding nonrelativistic bosons [ε=(2M) −1 p 2 ]. If the mass M is reduced to zero, the condensation temperature Tc grows monotonically and reaches eventually that of massless relativistic bosons. This mass-dependence of Tc is therefore distinct from the case of nonrelativistic bosons, where Tc grows to infinity as M →0. A brief discussion is given for a possible connection with the normal-to-super transition of the independently moving Cooper pairs (bosons). (shrink)

Reinforcement Learning (RL) handles policy search problems: searching a mapping from state space to action space. However RL is based on gradient methods and as such, cannot deal with problems with multimodal landscape. In contrast, though Genetic Algorithm (GA) is promising to deal with them, it seems to be unsuitable for policy search problems from the viewpoint of the cost of evaluation. Minimal Generation Gap (MGG), used as a generation-alternation model in GA, generates many offspring from two or more parents (...) selected from a population. Therefore, evaluating policies of generated offspring requires much trial and error (i.e. interaction between an agent and an environment). In this paper, we incorporate importance sampling into the framework of MGG in order to reduce the cost of evaluation on policy search. The proposed techniques are applied to Markov Decision Process (MDP) with multimodal landscape. The experimental results show that these techniques can reduce the number of interaction between an agent and an environment, and also mean that MGG and importance sampling are good for each other.

The mental fatigue elicited by working and studying consumed mental resources, thereby eliciting a declined performance and an increased mental stress. The long-term continuous work and study, which is typical for modern workers and students, can increase mental fatigue and health risks. Previous studies reported that the natural environment has a restorative of mental resources and reducing stress. However, it is difficult for urban workers and students to take sufficient breaks in real natural environment. We conducted an experiment to examine (...) whether brief and indirect exposure to the natural environment elicits a restorative of attention and reducing stress. Twenty-five undergraduate and graduate students from the university of modern city participated in the experiment. The experiment involved measuring the changes in the task performance of the participants and the subjective mental workload, while the attention restoration was indexed from physiological response over time. The participants had two types of resting periods in the middle of the task, i.e., by looking at a blank display or by watching a nature video having scenes of, e.g., a forest, small waterfall, and rustling leaves. The results indicate that the natural environment indirectly depicted through the nature videos does not affect the task performance and the subjective mental workload but decreases the SCL. The results of the physiological response suggest that having rest periods depicting the natural environment, even if indirectly and briefly, can restore the directed attention for the task. This experiment revealed a useful method of resting for urban workers and students to restore their attention to a task. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Death and Dying in JapanRihito Kimura (bio)A majority of Japanese, at present, feel that the modern biomedical and technological innovations pertaining to human life and death have been forcing a change in our common understanding of what, historically, was simply the natural event and process of death and dying. The meaning of death and the dying process in our lives is changing as have the traditional criteria for (...) determining death, namely, cessation of heartbeat and respiration.An individual’s death should be a personal and private matter as well as a familial, communal, and social matter. It has been regarded as such for many thousands of years in our Japanese society and culture. It is well understood that our traditional socio-cultural understanding of human life positively admits the natural process of death as the final event of life. The ideas expressed in Zen-Buddhist phrases such as “accept death as it is” and “life-death as one phenomenon” have been key motifs totally integrated into our traditional understanding of life (Tomomatsu 1939).However, the traditional perception of death as an acceptable process has [End Page 374] been vanishing as the Japanese have applied modern biomedical technologies more frequently in well-equipped hospital settings. Although the involvement of family members in the process of dying and particularly in the death event continues in a variety of ways, the care of dying patients in Japan is becoming much more similar to that delivered in advanced hospital settings in many countries of the world, than it is different. Now, in Japan, a majority of people end their lives in the hospital, surrounded by high-technology machines. Yet, in a survey by the Yomiuri Shimbun of 15 June 1991, half of the respondents said they would prefer to die at home.In addition, there has been a tradition of not explaining to terminally ill people the true nature of their condition, on the ground that this is most appropriate way to proceed (Kashiwagi 1994, pp. 78–85). However, views on this matter are changing. There is a gradual move toward telling patients the truth, and the notion of informed consent has been widely publicized in the clinical setting (Leflar 1996, pp. 96–107). In the 1991 nationwide opinion poll by the Yomiuri Shimbun, 65 percent of the participants said that they would like to be given full diagnostic information about themselves even if they were terminally ill. Nevertheless, only 22 percent of the people questioned said they themselves would definitely be prepared to disclose such information to a family member.The same survey indicated that 78 percent of people considered palliative care desirable, even though it might shorten life, while 16 percent thought life should be sustained as long as possible, irrespective of the pain that patients might be suffering.Challenges of Care for the DyingA special task force on terminal care, set up by the Ministry of Health and Welfare, issued a report in 1989 that encouraged the disclosure of diagnostic information to patients, provided that consideration was given to patients’ life histories, personalities, relationships with family members, and other factors. The report favored the use of drugs for pain control; it also dealt with matters such as spiritual requirements and the care of the family members.Traditionally, the physician-patient relationship in Japan is based on a complete and unquestioning trust of the physician by the patient, such that the physician acts to make health care decisions on behalf of the patient (Kimura 1991). However, increasingly it is believed that people should not have to accept without question the authority of doctors in the treatment of disease. Responsibility for the care of the dying should be shared between family members and all health professionals, not only physicians. Changes are needed in the mentalities of health care providers, patients, and family members, and it must be recognized that the medical system and institutions are not immutable (Annas and Miller 1994, pp. 374–76). [End Page 375]To complicate matters even further, although a patient’s family is informed of the incurable nature of the disease affecting their family member, the patient, as noted above, usually is not told of...

This paper reports on recent developments in the rise of bioethics in Japan. Much of the recent interest in bioethics in Japan is seen as a response to various civic movements. The women's liberation movement, access to equal opportunity, and the recognition of patients' rights and the importance of informed consent are among some of the movements influencing the development of bioethics in Japan. The author argues that this movement is to be encouraged and fostered by health care professionals, public (...) policy makers, as well as lay persons in Japan.
