The always vexed relationships between philosophy, theory, methodology, empirical work and their representations and legitimations have been thrown into chaos with the belated acknowledgement of the Anthropocene. Unsurprisingly, traditional Western thought may have been complicit, given its underlying anthropocentric assumptions and humanist commitments in education philosophy, theory and practice. The postcritical knowledge ecology developed here is applied to both a modest and responsible form of methodological inquiry in an ethnographic study of nature experience. Our contextualised experiment adds to the nascent (...) literature of an environmentally oriented education now demanded in the Anthropocene. (shrink)

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 notion of an entangled linear order gives a useful method to construct counter examples for such problems as the productivity of chain conditions, the square bracket partition relation and the existence of a large size monotonic subfunction. In particular, if there exists and ℵ1-entangled linear order then some consequences ofMA ℵ 1 or of wOCA fail. So, in which model ofZFC does an ℵ1-entangled linear order exist? Todorcevic [6] has shown if cf2ℵ 0=ω1 then there is an ℵ1-entangled linear (...) order of size ℵ1. And it is widely known that adding κ many Cohen reals adds such a linear order of size κ. In this note it is shown that adding asingle Cohen real is sufficient to get a maximal size ℵ1-entangled linear order. (shrink)

When making decisions, people tend to overweigh the impact of losses compared to gains, a phenomenon known as loss aversion. A moderate amount of LA may be adaptive as it is necessary for protecting oneself from danger. However, excessive LA may leave people few opportunities and ultimately lead to suboptimal outcomes. Despite frequent reports of elevated LA in specific populations such as patients with depression, little is known about what psychological characteristics are associated with the tendency of LA. Based on (...) the neurobiological studies of LA, we hypothesized that positive psychological wellbeing may be negatively associated with people's tendency of LA. In the present study, we set out to test this hypothesis in a sample of young adults. We evaluated LA using a decision-making task in which subjects were asked to decide whether to accept or reject a series of coin-toss gambles. Our results revealed that individuals with more advanced personal growth as assessed by the Ryff's Psychological Well-being Inventory showed reduced LA. To our knowledge, this is the first report demonstrating an association between positive psychological wellbeing and LA. These findings suggest that personal growth might be employed as interventional targets for correcting excessive LA in vulnerable populations. (shrink)

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)

Short-term motor practice leads to plasticity in the primary motor cortex. The purpose of this study is to investigate the factors that determine the increase in corticospinal tract excitability after motor practice, with special focus on two factors; “the level of muscle activity” and “the presence/absence of a goal of keeping the activity level constant.” Fifteen healthy subjects performed four types of rapid thumb adduction in separate sessions. In the “comfortable task” and “forceful task”, the subjects adducted their thumb using (...) comfortable and strong forces. In the “comfortable with a goal task” and “forceful with a goal task”, subjects controlled the muscle activity at the same level as in the C and F, respectively, by adjusting the peak electromyographic amplitude within the target ranges. Paired associative stimulation, which combines peripheral nerve stimulation and transcranial magnetic stimulation, with an inter-stimulus interval of 25 ms was also done. Before and after the motor tasks and PAS25, TMS was applied to the M1. None of the four tasks showed any temporary changes in behavior, meaning no learning occurred. Motor-evoked potential amplitude increased only after the FG and it exhibited a positive correlation with the MEP increase after PAS25, suggesting that FG and PAS25 share at least similar plasticity mechanisms in the M1. Resting motor threshold decreased only after FG, suggesting that FG would also be associated with the membrane depolarization of M1 neurons. These results suggest task-dependent plasticity from the synergistic effect of forceful muscle activity and of setting a goal of keeping the activity level constant. (shrink)

A change of gaze behavior at a small mistake moment is a natural response that reveals our own mistakes and suggests an apology to others with whom we are working or interacting. In this paper we investigate how robot gaze behaviors at small mistake moments change the impressions of others. To prepare gaze behaviors for a robot, first, we identified by questionnaires how human gaze behaviors change in such situations and extracted three kinds: looking at the other, looking down, and (...) looking away. We prepared each gaze behavior, added a no-gaze behavior, and investigated how a robot’s gaze behavior at a small mistake moment changes the impressions of the interacting people in a simple cooperative task. Experiment results show that the ‘looking at the other’ gaze behavior outperforms the other gaze behaviors and indicates the degrees of perceived apologeticness and friendliness. Keywords: Communication robots; gaze; mistake; mitigation. (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.

It is important to manage individuals’ personal data after their death to maintain their dignity or follow their wishes as much as possible. From this perspective, this report describes the real-world commercialization of immortal digital personalities, which gives eternal life to the deceased in a digital form. We identify the problems with the commercialization of deceased users’ images and personal data, which becomes postmortem entertainment. Considering these problems, we seek out the ideal form of deceased users’ personal data for commercialization. (...) We conduct a social survey to understand how ordinary Japanese people feel about the various types of publicly available services that use personal data after death, such as social network service logs. By analyzing our survey results approximately 20% of respondents would allow the commercial use of their personal data, such as browsing their social network service logs, if they could receive compensation during their lifetime.

Violence and warfare in prehistory have been intensely discussed in various disciplines recently. Especially, some controversies are found on whether prehistoric hunter-gatherers had been already engaged in inter-group violence and warfare. Japanese archaeology has traditionally argued that warfare has begun in the Yayoi period with an introduction of full-fledged agriculture though people in the Jomon period, when subsistence system had been mainly hunting and gathering, had not been involved in inter-group violence and warfare. However, Lawrence Keeley, Samuel Bowles, Steven Pinker, (...) and others have recently focused on archaeological data of human skeletal remains, especially remains with some injures, arguing that prehistoric hunter-gatherers had already initiated inter-group violence and warfare. This paper aims to summarize and examine recent arguments that address the relationship between violence or warfare and human evolution based on archaeological data. In the first place, we summarize the claims of Keeley, Bowles, and Pinker that warfare had already been initiated and was commonplace among prehistoric hunter-gatherers, as well as the counter-argument of Ferguson that these original data are problematic. Secondly, we summarize the available data on human skeletal remains from the Mesolithic period in Europe (between 11,000 BC and 3,500 BC) and argue that these data support Ferguson’s argument. In particular, the available data suggests that even though inter-group violence and warfare was present during this period, it was very sporadic. Finally, we discuss the implications of this study and suggest future directions. (shrink)

RESUMO Tendo em vista a importância que o conceito de modelização, advindo da Cibernética, possui para o pensamento de Iuri Lotman, este artigo visa discutir a maneira pela qual o raciocínio inerente ao procedimento modelizador se encontra presente numa das suas principais formulações, relativa à “invariante intelectual”, que elucida a ação exercida pelo mecanismo inteligente da cultura, capaz de assegurar a sua perenidade e, ao mesmo tempo, incitar a criação de novos textos. Para proceder a essa discussão, primeiramente serão retomados (...) os fundamentos do processo de modelização e sua relação com o fazer científico, com o intuito de indicar o que vem a ser o “modelo” e o tipo de inteligibilidade que ele é capaz de produzir. Ao explorar a centralidade que o procedimento modelizador possui nas formulações de Lotman, espera-se igualmente elucidar de que modo, para o autor, é possível construir uma compreensão semiótica muito singular acerca da linguagem e da cultura. ABSTRACT Considering the importance of the modelling concept from Cybernetics to Yuri Lotman’s thinking, this article aims to discuss how the inherent reasoning for the modeling procedure is found in one of its main formulations, related to “intellectual invariant,” which elucidates the action on the intelligent mechanism of the culture, capable of ensuring its perenniality while inciting the creation of new texts. In order to continue this discussion, the fundamentals of the modelling process and its relationship with the scientific doing will be firstly resumed to indicate the “model” and the type of intelligibility they are capable of producing. When exploring the centrality that the modeler procedure has in Lotman’s formulation, the author is equally expected to elucidate how it is possible to build a very singular semiotic understanding of language and culture.

Japanese English learners have difficulty speaking Double Object than Prepositional Object structures which neural underpinning is unknown. In speaking, syntactic and phonological processing follow semantic encoding, conversion of non-verbal mental representation into a structure suitable for expression. To test whether DO difficulty lies in linguistic or prelinguistic process, we conducted functional magnetic resonance imaging. Thirty participants described cartoons using DO or PO, or simply named them. Greater reaction times and error rates indicated DO difficulty. DO compared with PO showed parieto-frontal (...) activation including left inferior frontal gyrus, reflecting linguistic process. Psychological priming in PO produced immediately after DO and vice versa compared to after control, indicated shared process between PO and DO. Cross-structural neural repetition suppression was observed in occipito-parietal regions, overlapping the linguistic system in pre-SMA. Thus DO and PO share prelinguistic process, whereas linguistic process imposes overload in DO. (shrink)
