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)

Cette étude se focalise sur différentes méthodes utilisées pour l’analyse phonologique de la parole aphasique. Nous comparons des tâches expérimentales de répétition et de dénomination d’image, des tâches d’élicitation semi-structurées et de la parole naturelle. Nous montrons que le type de mots rencontrés, le type de consonnes ou encore le nombre de productions diffèrent selon la tâche. Si les protocoles expérimentaux permettent d’obtenir toutes les cibles voulues, les tâches d’élicitation semi-structurée permettent d’avoir un plus grand nombre d’occurrences de sons et (...) de mots et des productions subissant des transformations différentes.

Two studies aimed to examine cultural differences in social support provision, with or without solicitation, in Japan and the United States. In Study 1, we replicated a previous study with Japanese university students. We found that the Japanese participants did not provide social support when it was not solicited, as compared with when it was solicited. Furthermore, in Study 2, participants were asked to respond to a questionnaire regarding a hypothetical stressful situation experienced by a close other and to indicate (...) their willingness to provide support. We confirmed our hypothesis that Japanese participants hesitate to provide unsolicited support to close others, even when they recognize that the close others are in need, whereas the American participants do not hesitate to provide such support. Contrastingly, regarding solicited support, the Japanese and Americans were equally ready to provide support, as hypothesized. The cultural difference in social support resides in the provision of unsolicited support. These results suggest that differences in culturally appropriate responses to needy people are responsible for the difference in the provision of unsolicited vs. solicited social support. (shrink)

Let ℸ be the set of Gödel numbers Gn of function symbols f such that PRA ⊢ and let γ be the function such that equation imageWe prove: The r. e. set ℸ is m-complete; the function γ is not primitive recursive in any class of functions {f1, f2, ⃛} so long as each fi has a recursive upper bound. This implies that γ is not primitive recursive in ℸ although it is recursive in ℸ.

This paper discusses how to refine a given initial legal ontology using an existing MRD (Machine-Readable Dictionary). There are two hard issues in the refinement process. One is to find out those MRD concepts most related to given legal concepts. The other is to correct bugs in a given legal ontology, using the concepts extracted from an MRD. In order to resolve the issues, we present a method to find out the best MRD correspondences to given legal concepts, using two (...) match algorithms. Moreover, another method called a static analysis is given to refine a given legal ontology, based on the comparison between the initial legal ontology and the best MRD correspondences to given legal concepts. We have implemented a software environment to help a user refine a given legal ontology based on these methods. The empirical results have shown that the environment works well in the field of Contracts for the International Sale of Goods. (shrink)

BackgroundMany genetic counseling studies have focused on anxiety status because clients of GC often feel anxious during their visits. Metacognition is known to be one of the causes of having an inappropriate thinking style. In this study, we examined the relationship between anxiety and the metacognitive status of GC clients according to their characteristics.MethodsThe participants were 106 clients who attended their first GC session in our hospital from November 2018 to March 2021. The survey items were the clients’ characteristics, anxiety (...) status at the time of the visit, and metacognitive status.ResultsHigh state anxiety and high trait anxiety were observed in 34.9 and 11.3% of clients, respectively. Clients who were a relative or had a family history were significantly more likely to have high state anxiety. As for metacognitive status, only negative beliefs about thoughts concerning uncontrollability and danger were associated with having an anxiety status. Furthermore, multivariate analysis showed that negative beliefs about thoughts concerning uncontrollability and danger were an independent determinant of higher state anxiety, but not being a relative or having a family history. Metacognitive status scores were significantly lower in clients than in the control group.ConclusionState anxiety was shown to be more dependent on negative beliefs about thoughts concerning uncontrollability and danger of GC clients than their characteristics such as being a relative or having a family history. The results of this study will contribute to the development of new GC psychosocial support measures to address the anxiety of GC clients. (shrink)

McEntire (1984) proved that, for a portfolio problem with independent assets, the generalized harmonic mean plays the role of a risk-free threshold. Based upon this property, he developed a criterion for including or excluding assets in an optimal portfolio, and he proved an ordering theorem showing that an optimal portfolio always consists of positive amounts of the assets with the largest mean values. Also, some commonly used utility functions were shown to satisfy the property that the dominance of an asset (...) over another is unaffected by the addition of other assets. In this paper we extend these results to the case where assets are dependent. (shrink)
