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.

Gareth Evans proved that if two objects are indeterminately equal then they are different in reality. He insisted that this contradicts the assumption that there can be vague objects. However we show the consistency between Evans's proof and the existence of vague objects within classical logic. We formalize Evans's proof in a set theory without the axiom of extensionality, and we define a set to be vague if it violates extensionality with respect to some other set. There exist models of (...) set theory where the axiom of extensionality does not hold, so this shows that there can be vague objects. (shrink)

Let A[ω]ω be a maximal almost disjoint family and assume P is a forcing notion. Say A is P-indestructible if A is still maximal in any P-generic extension. We investigate P-indestructibility for several classical forcing notions P. In particular, we provide a combinatorial characterization of P-indestructibility and, assuming a fragment of MA, we construct maximal almost disjoint families which are P-indestructible yet Q-destructible for several pairs of forcing notions . We close with a detailed investigation of iterated Sacks indestructibility.

In ${\mathbf{H}}$ , a set theory with the comprehension principle within Łukasiewicz infinite-valued predicate logic, we prove that a statement which can be interpreted as “there is an infinite descending sequence of initial segments of ω” is truth value 1 in any model of ${\mathbf{H}}$ , and we prove an analogy of Hájek’s theorem with a very simple procedure.

This paper examines ethics in finance, specifically related to responsible investment. In recent years, socially responsible principles are becoming the de facto standard not only for socially responsible but also for profitable investing. For instance, the United Nations developed the Principles for Responsible Investment (PRI) in 2006, which require institutional investors to incorporate ESG (Environmental, Social and Governance) issues into investment analysis and decision-making processes. This raises the following question: can responsible investments be justified from an ethical point of view? (...) In this paper I first explain responsible investments. Then, I turn to the ethical foundation of responsible investments. There are two arguments for responsible investments. I argue that both fail. Therefore, my conclusion is that the ethical foundation of responsible investments is not firm. (shrink)

We prove a set-theoretic version of Hájek, Paris and Shepherdson's theorem [HPS00] as follows: The set ω of natural numbers must contain a non-standard natural number in any natural Tarskian semantics of CŁ0, the set theory with comprehension principle within Lukasiewicz's infinite-valued predicate logic. The key idea of the proof is a generalization of the derivation of Moh Shaw-Kwei's paradox, which is a Russell-like paradox for many-valued logic.

We introduce the simpler and shorter proof of Hajek’s theorem that the mathematical induction on ω implies a contradiction in the set theory with the comprehension principle within Łukasiewicz predicate logic Ł ${\forall}$ (Hajek Arch Math Logic 44(6):763–782, 2005) by extending the proof in (Yatabe Arch Math Logic, accepted) so as to be effective in any linearly ordered MV-algebra.

In my paper, I partially defend Philippa Foot’s view in answering the question ‘why be moral?’ In her book, Natural Goodness(2001) and her final paper, “Rationality and Goodness” (2004), Foot proposes two ideas: Ethical Naturalism and, what I call, the ‘Anti-Humean Theory of Practical Rationality’. In answering the question ‘why be moral?’, I argue that we should abandon the former and adopt the latter. In Section I, I discuss Foot’s Anti-Humean Theory of Practical Rationality. In Section II, I examine Foot’s (...) Ethical Naturalism. I argue that it is no longer defensible. In Section III, I examine other possible ways to integrate the categories of practical rationality. One is to take a utilitarian approach and another is to take a Kantian approach. I argue that the latter approach is in harmony with Foot’s Anti-Humean Theory of Practical Rationality. (shrink)

We propose a new game to strategically justify the constrained equal awards rule in claims problems. Our game is “procedurally fair” and “multilateral”. In addition, even if claimants cannot reach an agreement in any period, they can renegotiate in the next period. We show that, for each claims problem, the awards vector chosen by the constrained equal awards rule achieved at period 1 is the unique subgame perfect equilibrium outcome of the game.

Background Advance care planning (ACP) is a process in which adults engage in an ongoing dialogue about future medical treatment and care. Though ACP is recommended to improve the quality of end-of-life care, the details of the dialogue experience in ACP are unknown. Objective To explore participants’ experiences of dialogue in an ACP educational program that encouraged them to discuss the value of a way of life. Research design This qualitative descriptive study used the focus group interview method. Data were (...) analyzed using qualitative content analysis. Participants and research context A dialogue-based ACP educational program was conducted in four regions in Japan for local citizens to discuss the value of their way of life. A total of 66 individuals (mean age = 55.5 ± 17.2 years; 50 women and 16 men) participated in focus group interviews. Ethical considerations This study was approved by the Ethical Review Committee of Tokyo Women’s Medical University (no. 4723) and Kyoto University (no. R2099). Findings Five main themes were extracted: discussing one’s thoughts with others in a considerate manner, reflecting on one’s way of life through others, feeling a sense of connection with others through storytelling, realizing the difficulties of talking about “what if” topics, and turning one’s eyes toward the future through the dialogue. These themes were interrelated and illustrated the complexity of the experience of discussing values. Conclusions The results suggest that dialogue in ACP is useful in clarifying values. They also indicated the need for dealing with the ethical challenges of discussing value and the importance of caring for the interlocutor to have a safe dialogue. In the ACP process, safety in dialogue may improve readiness in ACP, and health practitioners who support ACP need to address the ethical challenges entailing dialogue about values. (shrink)

When people speak about “communication barriers”, what they usually think about are such things as the limitations set by human nature itself, or the constraints that are inherent in the tools we use for communicating. As an example of the first, consider the limited range of the naked human voice; for the second, we may think of the limitations imposed by such primitive communicative devices as the bonfire, the heliograph, or an old-fashioned megaphone.Our contribution draws attention to the fact that, (...) despite enormous advances on the technological side of human communication (such as demonstrated by the existence and use of computers as communication devices), there still are some barriers to be removed as far as the human side is concerned. We call these barriers the “stumble-blocks of the mind”. Their existence is demonstrated by the study of two case stories, which show that understanding the communicative implications of computerizing information is more important than increased emphasis on ever fancier and more expensive hardware products.The next question has to do with the reasons for these “stumbling blocks” to occur. Current communicative and linguistic theoretical findings are used in an effort to explain and solve the communicative dilemmas that are encountered in the organization of our communication, among others in the area of human-computer interface. In particular, the notion of “privacy” in speech acting is suggested as an overlooked aspect, and the notion of “information transfer” is replaced by that of “creating mental activity”.Finally, some conclusions are drawn, and a number of practical applications are offered.

This paper investigates the effects of group interaction in a storytelling situation for children using two robots: a reader robot and a listener robot as a side-participant. We developed a storytelling system that consists of a reader robot, a listener robot, a display, a gaze model, a depth sensor, and a human operator who responds and provides easily understandable answers to the children’s questions. We experimentally investigated the effects of using a listener robot and either one or two children during (...) a storytelling situation on the children’s preferences and their speech activities. Our experimental results showed that the children preferred storytelling with the listener robot. Although two children obviously produced more speech than one child, the listener robot discouraged the children’s speech regardless of whether one or two were listening. (shrink)

Eukaryotic genome DNA is wrapped around core histones and forms a nucleosome structure. Together with associated proteins and RNAs, these nucleosomes are organized three‐dimensionally in the cell as chromatin. Emerging evidence demonstrates that chromatin consists of rather irregular and variable nucleosome arrangements without the regular fiber structure and that its dynamic behavior plays a critical role in regulating various genome functions. Single‐nucleosome imaging is a promising method to investigate chromatin behavior in living cells. It reveals local chromatin motion, which reflects (...) chromatin organization not observed in chemically fixed cells. The motion data is like a gold mine. Data analyses from many aspects bring us more and more information that contributes to better understanding of genome functions. In this review article, we describe imaging of single‐nucleosomes and their tracked behavior through oblique illumination microscopy. We also discuss applications of this technique, especially in elucidating nucleolar organization in living cells. (shrink)

This article is an attempt to answer the question whether Descartes had read Sextus Empiricus’s Outlines of Pyrrhonism. At first glance, the question seems trivial. This question, however, is of historico-philosophical significance in that it reveals, even if only partially, what Descartes, who is regarded as the father of early modern philosophy, inherited from his earlier intellectual legacy in formulating his own philosophy. I first compare statements from Sextus’s Outlines with corresponding statements from Descartes’s writings to identify their similarities in (...) terms of content. This comparison focuses on their views regarding four subjects: the syllogistic, moral guidelines, the use of definitions, and true opinions. I then analyse and discuss whether the degree of similarity between these sets of statements is sufficient to conclude that the particular work of Descartes is based on Sextus’s arguments. This preliminary study can only provide indirect evidence that Descartes had read Sextus, for a thorough clarification of whether he read anything other than the works he himself stated that he had read (e.g., Cicero, Suárez), would require further circumstantial evidence, however weak it may be.

The evolution of altruism in human societies has been intensively investigated in social and natural sciences. A widely acknowledged recent idea is the “parochial altruism model,” which suggests that inter- group hostility and intragroup altruism can coevolve through lethal intergroup conflicts. The current article critically examines this idea by reviewing research relevant to intergroup conflicts in human evolutionary history from evolutionary biology, psychology, cultural anthropology, and archaeology. After a brief intro- duction, section 2 illustrates the mathematical model of parochial altruism (...) and some critiques of the model and its interpretation, primarily from an evolutionary biology point of view. Section 3 delves into the archaeological evidence of prehistoric intergroup conflicts in the Japanese archipelago’s Jomon and Yayoi periods, Europe’s Mesolithic period, and North America’s Pacific period as counter examples of the paro- chial altruism model. In section 4, the ethnographies of intergroup relationships and conflicts reveal that intergroup relationships in many ethnic groups are not as simple as the assumption in the mathematical model of parochial altruism. In section 5, we outline psychological research on intergroup conflicts which suggest that intergroup hostility and ingroup altruism are not necessarily correlated. In conclusion, we argue that the assumption and parameter settings of the parochial altruism model are inconsistent with empirical data. (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)
