The origins and consequences of warfare or largescale intergroup violence have been subject of long debate. Based on exhaustive surveys of skeletal remains for prehistoric hunter-gatherers and agriculturists in Japan, the present study examines levels of inferred violence and their implications for two different evolutionary models, i.e., parochial altruism model and subsistence model. The former assumes that frequent warfare played an important role in the evolution of altruism and the latter sees warfare as promoted by social changes induced by agriculture. (...) Our results are inconsistent with the parochial altruism model but consistent with the subsistence model, although the mortality values attributable to violence between hunter-gatherers and agriculturists were comparable.

The causes of prehistoric inter-group violence have been a subject of long-standing debate in archaeology, an- thropology, and other disciplines. Although population pressure has been considered as a major factor, due to the lack of available prehistoric data, few studies have directly examined its effect so far. In the present study, we used data on skeletal remains from the middle Yayoi period of the Japanese archipelago, where archaeologists argued that an increase of inter-group violence in this period could be explained (...) by a population-pressure hy- pothesis. We quantitatively examine the effect of population pressure on the frequency of inter-group violence by compiling an exhaustive data set. We collected demographic information based on burial jars (kamekan) and the frequency of violence based on the ratio of injured individuals. The results are consistent with the hypothesis, i. e., high population density can promote inter-group violence. (shrink)

It has been commonly claimed that prehistoric warfare in Japan began in the Yayoi period. Population increases due to the introduction of agriculture from the Korean Peninsula to Japan resulted in the lack of land for cultivation and resources for the population, eventually triggering competition over land. This hypothesis has been supported by the demographic data inferred from historical changes in Kamekan, a burial system used especially in the Kyushu area in the Yayoi period. The present study aims to examine (...) the previous claim by using an expanded dataset of human skeletal remains and Kamekan. First, in order to quantify the intensity of warfare, we developed a database of injured individuals found in the middle phase of the Yayoi period in two large populations in the northern Kyushu area, the Fukuoka plain and the upperand middle-stream of the Homan River. Second, we collected Kamekan data from site reports published after 1990 and constructed a comprehensive database to infer the demography in these areas. Finally, we compared the frequency of injured individuals and the inferred demography. The results suggest that the frequency of injured individuals and the population increase tended to be higher at the upper- and middle-stream of the Homan River than on the Fukuoka plain. Different assumptions of the lifetime of each type of Kamekan can produce mixed results on the relationship between demography and the frequency of injured individuals. They were positively correlated under the traditional assumption of constant time intervals, while there was no correlation using time intervals based on carbon dating by the National Museum of Japanese History. Thus, our results are partially consistent with the previous claim that the population increase and the lack of land and resources due to the introduction of agriculture were causes of warfare in the northern Kyushu area in the middle phase of the Yayoi period.

Whether man is predisposed to lethal violence, ranging from homicide to warfare, and how that may have impacted human evolution, are among the most controversial topics of debate on human evolution. Although recent studies on the evolution of warfare have been based on various archaeological and ethnographic data, they have reported mixed results: it is unclear whether or not warfare among prehistoric hunter – gatherers was common enough to be a component of human nature and a selective pressure for the (...) evolution of human behaviour. This paper reports the mortality attributable to violence, and the spatio-temporal pattern of violence thus shown among ancient hunter–gatherers using skeletal evidence in prehistoric Japan (the Jomon period: 13000 cal BC–800 cal BC). Our results suggest that the mortality due to violence was low and spatio-temporally highly restricted in the Jomon period, which implies that violence including warfare in prehistoric Japan was not common.

The origins of Japan's medical ideas, which are deeply rooted in its religion, culture and history, are not widely understood in medical societies of other countries. We have taken up the task of summarising this tradition here so that some insight can be gained into the unique issues that characterise the practice of medicine in Japan. We borrow from the sayings of Tohkaku Wada, a medical philosopher of late eighteenth-century Japan, for a look at Japanese medical tradition. Wada's medical thought (...) was very much reflective of the Buddhism, Zen, and swordsmanship that informed eighteenth-century philosophy in Japan. His central concepts were “chu” and “sei”, that is, complete and selfless dedication to the patient and the practice of medicine. This paper explores Wada's thought, explaining it mainly from the standpoint of Japanese traditional culture. (shrink)

This study examined the ability to comprehend conventional and non-conventional implicatures, and the effect of proficiency and learning context on comprehension of implicature in L2 Chinese. Participants were three groups of college students of Chinese: elementary-level foreign language learners, advanced-level foreign language learners, and advanced-level heritage learners. They completed a 36-item computer-delivered listening test measuring their ability to comprehend three types of implicature: conventional indirect refusals, conventional indirect opinions, and non-conventional indirect opinions. Comprehension was analyzed for accuracy and comprehension speed. (...) There was a significant effect of implicature type on accuracy, but not on comprehension speed. A significant effect of participant group was observed on accuracy, but the effect was mixed on comprehension speed. (shrink)

Harmony is one of the most fundamental Japanese values. It is derived from Confucianism and encompasses a state of mind, an action process and outcomes of the action. This article draws on research data and discusses Japanese nurses’ perceptions of harmony as reflected in their everyday practice. The most important virtues for these nurses were reported as politeness and respect for other persons. The outcome from the nurses’ harmonious practice, it is claimed, benefited patients and created peaceful, harmonious relationships for (...) all. Because of the unique link between harmony and the location of interaction, the ideal ‘workplace harmony’ threatened some nurses’ professional decision making. These nurses confused harmony with conformity by superficial agreement. The Japanese seniority system could be a major factor contributing to this problem. Ethics education that includes traditional values and concepts in Japanese culture is strongly urged. (shrink)

Although we have learned much about the neuropsychological control of facial expressions of emotion, there is still much work to do. We suggest that future work integrate advances in our theoretical understanding of the roles of volition and consciousness in the elicitation of emotion and the production of facial expressions with advances in our understanding of its underlying neurophysiology. We first review the facial musculature and the neural paths thought to innervate it, as well as previous attempts at understanding the (...) neural control of facial expressions of emotion, focusing on the voluntary-involuntary dichotomy and studies of hemispheric specialization. In the second section, we discuss four major aspects of the psychology of facial expressions of emotion that have particular import to their neurophysiological substrates. We offer these as a starting point for a better integration of psychological and neurophysiological perspectives in considering the neuropsychological control of facial expressions of emotion.

In this paper, I discuss the problems of ``order in social situations'' using a computer simulation of iterated N -person prisoners' dilemma game. It has been claimed that, in the case of the 2 -person prisoners' dilemma, repetition of games and the reciprocal use of the ``tit-for-tat'' strategy promote the possibility of cooperation. However, in cases of N -person prisoners' dilemma where N is greater than 2, the logic does not work effectively. The most essential problem is so called ``sanctioning (...) problems''. In this paper, firstly, I discuss the ``sanctioning problems'' which were introduced by Axelrod and Keohane in 1986. Based on the model formalized by Axelrod, I propose a new model, in which I added a mechanism of players' payoff changes in the Axelrod's model. I call this mechanism norm-internalization and call our model `` norm-internalization game ''. Second, by using the model, I investigated the relationship between agents' norm-internalization (payoff-alternation) and the possibilities of cooperation. The results of computer simulation indicated that unequal distribution of cooperating norm and uniform distribution of sanctioning norm are more effective in establishing cooperation. I discuss the mathematical features and the implications of the results on social science. (shrink)

Human beings express affinity (Shinwa‐kan in Japanese language) in communicating transactive engagements among healthcare providers, patients and healthcare robots. The appearance of healthcare robots and their language capabilities often feature characteristic and appropriate compassionate dialogical functions in human–robot interactions. Elements of healthcare robot configurations comprising its physiognomy and communication properties are founded on the positivist philosophical perspective of being the summation of composite parts, thereby mimicking human persons. This article reviews Mori's theory of the Uncanny Valley and its consequent debates, (...) and examines "Uncanny" relations with generating healthcare robot conversational content with artificial affective communication (AAC) using natural language processing. With healthcare robots provoking influential physical composition and sensory expressions, the relations in human–healthcare robot transactive engagements are argued as supportive of the design and development in natural language processing. This implies that maintaining human–healthcare robot interaction and assessing the eeriness situations explained in the Uncanny Valley theory are crucial positions for healthcare robot functioning as a valuable commodity in health care. As such, physical features, language capabilities and mobility of healthcare robots establish the primacy of the AAC with natural language processing as integral to healthcare robot–human healthcare practice.

Climate change is often tackled via a two-pronged approach of behaviour change and technological advancement. Policy studies and social sciences generally take ownership of influencing behaviours, while natural sciences and engineering tackle generating newer, more efficient technologies. Fusion of these methodologies is severely lacking. Engineers are uniquely situated to contribute to positive environmental action in both technological and behavioural realms. This article explores the psychological mindset of engineers as they make decisions to dissect factors that undermine sustainable behaviour. The Theory (...) of Planned Behaviour, Multi-Criteria Decision Analysis and the Health Belief Model are applied to engineering decision making to develop a methodology for engineers to modify their behaviour to consistently make more sustainable choices, and in turn, assist others by making actions towards sustainability more convenient.

BackgroundEmotional regulation is important for adolescents’ adaptive development. Preventive interventions for anxiety and depression are necessary for reducing the development of disorders later in life, and emotional regulation is a potentially relevant factor.ObjectiveWe investigated the effects of a mindfulness-based psychological education and prevention program [the Mindfulness and Awareness Program ] on the mental health of junior high school students in Japan.MethodsOur MAP primarily focused on mindfulness meditation to improve emotional regulation, thereby reducing depression and anxiety. The MAP comprised eight sessions (...) administered by a school counselor in a school setting. All participants were 12–13-year-old adolescents from nine classes in two Japanese schools. The program was provided to the intervention group, wherein students were educated on emotional expression, emotional cognition, and emotional regulation. The control group received regular school counseling services.ResultsCompared with the control group, the intervention group showed significant improvement in emotional regulation and a decrease in depression and generalized anxiety. The effect was greater at the follow-up assessment than at the immediate post-intervention assessment, and greater in female students.ConclusionOur mental health prevention program exhibited efficacy in reducing depression and anxiety and enhancing emotional regulation in early adolescence. Further, it appeared to be more effective for female adolescents. (shrink)

To preserve postoperative brain function, it is important for neurosurgeons to fully understand the brain's structure, vasculature, and function. Intraoperative high-frequency electrical stimulation during awake craniotomy is the gold standard for mapping the function of the cortices and white matter; however, this method can only map the “focal” functions and cannot monitor large-scale cortical networks in real-time. Recently, an in vivo electrophysiological method using cortico-cortical evoked potentials induced by single-pulse electrical cortical stimulation has been developed in an extraoperative setting. By (...) using the CCEP connectivity pattern intraoperatively, mapping and real-time monitoring of the dorsal language pathway is available. This intraoperative CCEP method also allows for mapping of the frontal aslant tract, another language pathway, and detection of connectivity between the primary and supplementary motor areas in the frontal lobe network. Intraoperative CCEP mapping has also demonstrated connectivity between the frontal and temporal lobes, likely via the ventral language pathway. Establishing intraoperative electrophysiological monitoring is clinically useful for preserving brain function, even under general anesthesia. This CCEP technique demonstrates potential clinical applications for mapping and monitoring large-scale cortical networks. (shrink)

In the name of efficiency, the practice of education has come to be dominated by neoliberal ideology and procedures of standardization and quantification. Such attempts to make all aspects of practice transparent and subject to systematic accounting lack sensitivity to the invisible and the silent, to something in the human condition that cannot readily be expressed in an either-or form. Seeking alternatives to such trends, Saito reads Dewey’s idea of progressive education through the lens of Emersonian moral perfectionism (to borrow (...) a term coined by Stanley Cavell). She elucidates a spiritual and aesthetic dimension to Dewey’s notion of growth, one considerably richer than what Dewey alone presents in his typically scientific terminology. (shrink)

Researchers have been interested in what retrieval process is responsible for overgeneral autobiographical memories (OGM) in depression. Previous cross-sectional studies demonstrated that, for negatively valenced cues, directly retrieved OGM, rather than generatively retrieved OGM, are associated with depression. However, longitudinal evidence of this relationship is still lacking and needs to be tested. We conducted a re-analysis of the online computerised memory specificity training (c-MeST) data to examine whether directly retrieved OGM for negative cues prospectively predicts high levels of depression 1 (...) month later. Participants who met the criteria of current major depressive disorders (N = 116; n = 58 in the c-MeST group and n = 58 in the control group) recalled autobiographical memories for positive and negative cues and judged each retrieval process (i.e. direct or generative). The results supported our prediction, and directly retrieved OGM for negative cues predicted high levels of depressive symptoms 1 month later even after controlling for the group effect, baseline depressive symptoms, executive functioning and rumination. Exploratory analysis showed that direct retrieval of specific memories prospectively predicted low levels of depression. These results support the theory that elevated accessibility of negatively valenced general memory representations is a vulnerability factor for depressive symptoms. (shrink)

ναξ and βασιλες are the two most important titles applied to the top stratum of Homeric aristocracy., usually translated as ′lord′ or ′master′, and βασιλες, usually translated as ′king′, often apply to the same individuals, and can at times appear to be very close in meaning, allowing translators to render ναξ as ′king′ and βασιλες as ′lord′. There are, however, significant differences between the two. As Lexikon des friihgriechischen Epos now conveniently summarizes for us, avat; can be divine or human, (...) can be a master of a state, of gods, of men, of animals, or of his household, and can be used as an address in the vocative, whereas fiaoiXevs is only applied to humans in Homer, often in a political context, and is never used in the vocative.

Phoenix's speech in Book 9 of the Iliad is generally considered prophetic of what happens to Achilles later in the story. Many scholars have argued that Achilles is punished by Zeus through τη which causes the death of Patroclus, just as anyone who spurns the Litai in the allegory of Phoenix will be punished by Ate sent by Zeus. The Meleager episode is also regarded as reflecting almost exactly what happens later: the Achaeans have difficulty in the battle due to (...) Achilles' withdrawal, just as the Aetolians have when Meleager refuses to fight. Achilles, like Meleager, receives a set of three supplications to go back to the battle, and, just as Meleager loses his prize because he rejects the supplications, Achilles loses Patroclus because he does not listen to the pleas of the Embassy. This seems to be, in outline, the present orthodoxy. (shrink)

A multitude of global challenges that society grapples with, including climate change, social injustices, and economic disparities, persist largely due to the shortcomings of effectively responding to complex systems. In this article, we consider adopting systems literacy as a comprehensive educational approach to navigate in complex systems. We advocate for a systems literacy pedagogy that employs an affective-relational-cognitive (ARC) framework for learning, emphasizing active engagement and intervention in the world. The concept of systems beings is rooted in both ontological education (...) and systems literacy, and we propose the ARC framework as both a pedagogical theory and practice to further understand and engage with it. This is further explored through an educational example of a transdisciplinary doctoral pilot project focused on the climate emergency. (shrink)
