BackgroundBoth impairment and sex differences in social cognition and neurocognition have been documented in schizophrenia. However, whether sex differences exist in the association between social cognition and neurocognition are not known. We aimed to investigate the contribution of areas of neurocognition to theory of mind and hostility bias, representing social cognition, according to sex in early course schizophrenia.MethodsIn this cross-sectional study, we assessed neurocognition using the Japanese version of the Brief Assessment of Cognition in Schizophrenia and assessed the ToM and (...) hostility bias subdomains of social cognition using the Social Cognition Screening Questionnaire in 131 participants diagnosed with schizophrenia within 5 years of onset. Sex differences were analyzed using t-tests. The associations of neurocognitive subdomains with ToM and hostility bias according to sex were analyzed using multiple regression analysis. Results were adjusted by age, estimated premorbid intelligence quotient, and symptomatology.ResultsNo sex differences were found in ToM or hostility bias. Higher verbal fluency was significantly associated with higher ToM in females, whereas higher executive function was significantly associated with higher ToM in males. Higher verbal fluency was significantly associated with lower hostility bias in females, whereas neurocognition and hostility bias were not significantly associated in males.ConclusionThe results suggest that neurocognition associated with social cognition differ according to sex. These differences should be considered for more effective treatment of social cognition. (shrink)

This article presents research on robot therapy for elderly residents in a care house. Experiments were conducted from June 2005, lasting more than 2 months. Two therapeutic baby seal robots were introduced to the residents, and activated for over 9 hours daily. To investigate the psychological and social effects of the robots, the residents’ activities in public areas were recorded using video cameras, during the daytime for over 2 months. In addition, urinalysis of the residents was performed for 17-ketosteroid sulfate (...) and 17-hydroxycorticosteroid. Results of the video analysis indicated that social interaction increased through interaction with the seal robots. Results of the urine tests showed that the reactions of the subjects’ vital organs to stress improved after the introduction of the robots. (shrink)

Metadata helps users locate resources that meet their specific needs. But metadata also helps us to understand the data we find and helps us to evaluate what we should spend our time on. Traditionally, staff at libraries, archives, and museums (LAMs) create metadata for the content they manage. However, social metadata—content contributed by users—is evolving as a way to both augment and recontextualize the content and metadata created by LAMs. Many cultural heritage institutions are interested in gaining a better understanding (...) of social metadata and also learning how to best utilize their users' expertise to enrich their descriptive metadata and improve their users' experiences.

Jainism is characterized by an observance of non-violence (ahimsa) and asceticism (tapas). In the field of philosophy, it is marked by the doctrine of manifold aspects (anekantavada). The purpose of this study is to explore the inseparable connection between Jainism as a religion and as a philosophy. The first chapterdescribes the position of philosophical thinking in Jainism, while the second examines the doctrine of manifold aspects, which has become synonymous with Jainism. These exploration makes it clear that most of Jaina (...) philosophers have not moved beyond their religious framework into the realm of pure philosophy, even though they have developed philosophical doctrine called the doctrine of manifold aspects. Finally, I introduce Haribhadra’s statement that could becalled an ideal form of the doctrine of manifold aspects. He deals with Kapila (thought to be the founder of the Samkhya school) impartially, and he deals with Mahavira, who founded Jainism, critically. It is interesting that such an idea was stated by a philosopher who was placed in a religious framework. Though thismay be a rare case, it shows the possibility that the philosophical thinking of Jainism has the potential to go beyond its own religious framework. (shrink)

Our empirical beliefs beyond sense impressions and the memories of them cannot be justified. Logically we must be complete skeptics. This is the consequence of Hume’s skeptical argument against induction. Should we accept this conclusion or not? This is the so-called problem of induction. In this paper I propose a new solution that belongs to the 'dissolutionist’ tradition (Strawson 1952, Okasha 2001). Through criticizing the core argument in Hume’s skepticism I claim the following: Hume’s skepticism against induction does not succeed (...) in denying the soundness of induction. We are not required to justify induction generally. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:The Japan Society for Buddhist-Christian Studies:A Report on the 2008 Annual MeetingTerao KazuyoshiThe 2008 annual meeting of the Japan Society for Buddhist-Christian Studies was held at the Palace Side Hotel in Kyoto on 1–3 September. The main theme of the meeting was the "Possibility of Religious Philosophy." The meeting consisted of four sessions, one research presentation, and a general overview on the final day.Two sessions were staged on the (...) first day. They dealt with a reconsideration of the religious philosophy of Jan Van Bragt (1928–2007), following the meeting in 2007, which generally covered his academic contributions. First, Keta Masako (Kyoto University) read a paper titled "A Configuration in the Contemporary World: A Response to Jan Van Bragt's Expectation and Disappointment at the Kyoto School of Philosophy." (Unfortunately I was unable to attend this session, so I am not able to summarize the presentation.) Next, Hanaoka Eiko (Nara University of Industry) presented a paper titled "In Search of the New Possibility of Religious Philosophy: Fundamental Experience and a Turning Point for Philosophy." She insisted that we need to keep in mind an overview of the religious philosophies of Nishida Kitaro, Tanabe Hajime, and Nishitani Keiji in order to understand Van Bragt's criticism of the Kyoto school. Nishida's ideas of the "logic of the place of nothingness" and the "unity of mind and body" work together, she suggested; this polarity was "one," in accordance with the idea of the "self-identity of absolute contradictions." But in Hanaoka's opinion, Van Bragt sometimes placed a disproportionate emphasis on one side of the polarity. Hanaoka identified ten polarities in Nishida's absolute nothingness: (1) philosophy of self-awareness and philosophy of existence, (2) substantial philosophy and non-substantial philosophy, (3) experience and rationality, (4) plurality and unity, (5) continuity and discontinuity, (6) temporality and eternity, (7) matter and spirit, (8) process and reality, (9) true self and ego, and (10) philosophy and the philosophy of philosophy. Hanaoka argued that Van Bragt's doubts would have disappeared if he had fully experienced love as that which emanates from the "oneness" of the polarity of absolute nothingness.On the second day of the meeting, Peter Baekelmans gave a presentation titled "The Faith of The Awakening Faith in Mahayana." While Baekelmans studied Buddhism, [End Page 147] particularly esoteric Buddhism, at Koyasan University, he became acquainted with the Daijōkishinron (The awakening faith in Mahayana) and began to translate it into English. He found that the Hindu term śraddhā meant both "hope for achieving the goal" and "confidence in the method," and that the former corresponded to the "faith of Mahayana" and the latter to the "generation of faith of Mahayana." Baekelmans then attempted to demonstrate that the Awakening of Faith was composed in India. In addition, from the perspective of phenomenology he argued that belief as the essence of the religious phenomenon and practice as the phenomenon itself together form a unified spirituality. The deeper that belief becomes, he said, the less important the difference between belief and practice becomes. Some textual scholars in the audience objected to that line of thought, suggesting that we needed more circumspect analysis in order to accept such a perspective.At the third session, Kim Seung-Chul (Kinjōgakuin University) read a paper on "Christian Theology Facing Religion and Science." He called the relation of religion and science a "double reflection," referring to theories by sociobiologist Edward O. Wilson and philosopher of science Ian Barbour. Kim interpreted religion and science in Nishitani as a "superposition" of existential order. Kim focused on two meanings of nondiscrimination according to Nishitani: "nondiscrimination in nature," found in science, and "nondiscrimination in love," found in religion. The former was symbolized by matter and the latter by life. The place where these two nondiscriminations coincide, he said, is exactly the "standpoint of emptiness." Kim concluded that we must recognize that this "standpoint of emptiness" was the place where the "problem of Christianity and other religions" and the "problem of Christianity and science" can be dealt with simultaneously as "in an absolutely equal status" for their resolution.Kobayashi Enshō (Hanazono University), the respondent to Kim's paper...

What Does Only Assert and Entail? This paper investigates the semantics of English only and two equivalent expressions in Japanese -dake and -shika, giving attention to two aspects: the debate over the status of two propositions that are involved in the use of ONLY expressions and the semantic and pragmatic differences among ONLY items, if any. We claim that a sentence with ONLY expressions entails both the affirmative and negative propositions. This view raises issues with Horn's original claim as well (...) as van Rooij and Schulz's while supporting Atlas and Horn. We claim then that the difference in strength between the affirmative and negative propositions emerges from what is asserted by that sentence. One of the bases for our claim is that there is a significant difference in behavior between entailment and assertion of a given sentence, following Horn. This difference explains the difference between -dake on the one hand and -shika and -only on the other: -dake differs from only and -shika in that it asserts the affirmative proposition while -shika and only asserts the negative proposition.

Though there has been an array of methods to evaluate the extent of sarcoidosis, it is generally difficult to detect central nervous system involvement. Recently it has become accepted that 18F-FDG PET is more sensitive than gallium scintigraphy in finding sarcoid lesions, however its usefulness and limitations for detecting sarcoidosis in the central nervous system, especially in the spinal cord, has rarely been investigated. Two patients with pathologically confirmed sarcoidosis manifested spinal symptoms. We conducted 18F-FDG PET along with conventional imagings (...) before and after treatment. Abnormal FDG uptakes which could not be detected by gallium scintigraphy were shown in the spinal cords in both patients. These abnormal uptakes were diminished in accordance with clinical improvement after treatment. Our findings suggest that 18F-FDG PET is effective in detecting and tracking the activity of spinal sarcoidosis. (shrink)

We examined amygdala subregion volumes in patients with a first episode of major depression and in healthy subjects. Covariate-adjusted linear regression was performed to compare the MD and healthy groups, and adjustments for age, gender, and total estimated intracranial volume showed no differences in amygdala subregion volumes between the healthy and MD groups. Within the MD group, we examined the association between amygdala subregion volume and the 17-item Hamilton Rating Scale for Depression score and the HAMD subscale score, and found (...) no association in the left amygdala. In the right amygdala, however, there was an inverse linear association between the HAMD total and the HAMD core and lateral nucleus and anterior-amygdaloid-regions. Furthermore, an inverse linear association was seen between the HAMD psychic and the lateral nucleus, anterior-amygdaloid-regions, transition, and whole amygdala. The findings of this study suggest that the severity of MD and some symptoms of MD are associated with right amygdala volume. There have been few reports on the relationship between MD and amygdala subregional volume, and further research is needed to accumulate more data for further validation. (shrink)

Introduction: Physical distancing under the coronavirus disease 2019 pandemic had a significant impact on lifestyles, including exercise routines. In this study, we examined the relationship between mental health and addictive behaviors, such as excessive exercise and the use of image and performance enhancing drugs across 12 sport disciplines.Materials and methods: A large cross-sectional sample of the adult population was surveyed. The mean age was 33.09. The number of male participants was 668. The use of IPEDs was assessed in conjunction with (...) psychometric measures such as the Exercise Addiction Inventory and the Appearance Anxiety Inventory. The participants were grouped into activity group and non-activity group according to the presence or absence of their exercise habits. The results were compared between these groups, as well as across sport disciplines, while taking into account the relationship between different psychological measures and IPEDs consumption.Results: The frequency of IPEDs use was higher among AG than NAG, although AG participants reported less history of addictions than NAG. The logistic regression analysis revealed that scores equal to or above cutoff points, in both the EAI and AAI, predicted the IPEDs use. Regarding the differences across the various sport disciplines, those who were involved in practicing Weight Lifting and Cross Fit were found to be more at risk of excessive exercising and more inclined to use a wide range of IPEDs.Conclusions: Although exercise could help to increase well-being and prevent addictions during the COVID-19 pandemic, our results show that those in the AG are particularly vulnerable to excessive IPEDs use. Sport disciplines associated with higher EAI and AAI scores have also shown a higher tendency to excessive IPEDs use. Furthermore, the factor of having above the cutoff scores in EAI or AAI in each sport could indicate larger IPEDs consumption regardless of the discipline. In light of the current findings, it is necessary to better define the “non-excessive” levels of exercise in various sport disciplines and an adequate intake of IPEDs to ensure the safety and well-being of people during a pandemic.
