The attributable fraction (population) has attracted much attention from a theoretical perspective and has been used extensively to assess the impact of potential health interventions. However, despite its extensive use, there is much confusion about its concept and calculation methods. In this article, we discuss the concepts of and calculation methods for the attributable fraction and related measures in the counterfactual framework, both with and without stratification by covariates. Generally, the attributable fraction is useful when the exposure of interest has (...) a causal effect on the outcome. However, it is important to understand that this statement applies to the exposed group. Although the target population of the attributable fraction (population) is the total population, the causal effect should be present not in the total population but in the exposed group. As related measures, we discuss the preventable fraction and prevented fraction, which are generally useful when the exposure of interest has a preventive effect on the outcome, and we further propose a new measure called the attributed fraction. We also discuss the causal and preventive excess fractions, and provide notes on vaccine efficacy. Finally, we discuss the relations between the aforementioned six measures and six possible patterns using a conceptual schema. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:The Nature (Ziran 自然) of Technological and Economic Development in Early DaoismYumi Suzuki (bio)I. IntroductionEric Nelson's Daoism and Environmental Philosophy: Nourishing Life provides comprehensive guidance on how early and later Daoist thought could offer both ideological and practical solutions to contemporary environmental issues. Nelson does not simple-mindedly claim that Daoists are environmentalists or that Daoism is comparable with modern environmental thought. His monograph has a more sophisticated, and (...) also more ambitious and consequently philosophically provocative, goal: to evolutionally develop old Daoist thought to directly address contemporary philosophical discourses on the environment.1I have summarized elsewhere what I find to be the most significant and meaningful contributions this book has made.2 I think its goal has successfully been achieved in various ways: Nelson gives careful and accurate interpretations to each passage from the original texts.3 What he calls "the new Daoism" deployed on the basis of these interpretations is reasonable and uncontroversial. The monograph overall offers an exemplary model of how wisdom acquired through studying the history of philosophy can be adapted to cogitating on newly emerging philosophical questions, despite differences in the intellectual contexts that we are required to warily distinguish. Moreover, by focusing on the Daoist tradition in East Asia, it well demonstrates how other systems of philosophical thought can be usefully employed to critically reflect on fundamental assumptions that an existing system is already committed to and that could be the very cause of relevant philosophical and pragmatic problems.While I mostly agree with his arguments in chapters 1–4 and 6, the only part I found unsatisfactory is chapter 5, "Early Daoist Biopolitics and a New [End Page 771] Daoist Political Ecology" (pp. 100–118). The present review aims to elaborate reasons for my resistance to Nelson's all-out endorsement of what he regards as the sociopolitical implications of Daoism. When it comes to politics, it appears to me, early Daoist texts such as the Daodejing and the Zhuangzi express often disappointingly ambiguous and agnostic attitudes toward what can be done with respect to their doctrinal opponents and outsiders. My suggestion is that if we examine the explorations of their contenders, that is, mainly Confucians and Legalists, concerning political and technological devices, they may present an altogether less biased and more balanced range of solutions to a question Nelson raises regarding an environmental challenge associated with a competitive globalized economy and rapidly developing technologies in our modern age.II. A Challenge to the Current Environmental MovementChapter 5 begins with the following statement:Appeals to encountering the myriad things in their environmental contexts and relations are necessary for an ecological transformation of existing cultures and societies. Yet an environmental ethos and culture of nature is not sufficient given how systematically reproduced social-economic processes in advanced capitalist societies meditate, entangle, and obstruct the transformative potential of such encounters. To this extent, an adequate environmental philosophy must concurrently be social-political philosophy that can offer an environmentally oriented critique of existing social structures and institutions that directly and indirectly harm creatures and degrade ecosystems in myriad ways such that transformations must transpire in economic and societal structures as well as at the level of individual cultivation and reflections.(p. 100)Nelson maintains that even though it is cardinal to transform the ways in which the myriad things encounter and mutually correspond with each other, as well as alter their own existential state, by cultivating an environmental ethos and culture of nature in each individual and society, one of the most serious challenges for such transformations could originate with already existing capitalist, materialist, and consumerist social structures and institutions widely prevailing and deeply embedded in the highly complex economic and political systems of our age.This, I think, captures the core problem of modern environmentalism. An individual, a group of people such as nonprofit or nongovernmental organizations, or a single city or country might be convinced by the Daoist "biospiritual" mode of life. Nevertheless, it appears to be far more difficult in practice to have certain countries or multinational mega-firms abandon their steadfast, primary commitment to national, industrial, commercial, or corporate missions to pursue their own benefits that deprioritize or...

This paper studies a sender-receiver game in which both players want the receiver to choose the state-optimal action. Before observing the state, the sender observes a “contextual signal,” a payoff-irrelevant signal that correlates with states and is imperfectly shared with the receiver. Once the sender observes the state, the sender sends a message to the receiver, incurring a small messaging cost. It is shown that there is no miscommunication in any efficient equilibrium if the messaging cost is uniform or contextual (...) information is poorly shared between players. However, if the messaging costs are different between some messages, and contextual information can affect the probability ranking of states and is shared reasonably well, any efficient equilibrium that favors the sender exhibits miscommunication. Furthermore, the messages that cause miscommunication can be coarse or ambiguous, depending on how well players share contextual information. (shrink)

The individual physical appearances of robots are considered significant, similar to the way that those of humans are. We investigated whether users prefer robots with male or female physical appearances for use in daily communication situations and whether egalitarian gender role attitudes are related to this preference. One thousand adult men and women aged 20–60 participated in the questionnaire survey. The results of our study showed that in most situations and for most subjects, “males” was not selected and “females” or (...) “neither” was selected. Moreover, the number of respondents who chose “either” was higher than that who chose “female.” Furthermore, we examined the relationship between gender and gender preference and confirmed that the effect of gender on the gender preference for a robot weakened when the human factor was eliminated. In addition, in some situations for android-type robots and in all situations for machine-type robots, equality orientation in gender role attitudes was shown to be higher for people who were not specific about their gender preferences. It is concluded that there is no need to introduce a robot that specifies its gender. Robots with a gender-neutral appearance might be more appropriate for applications requiring complex human–robot interaction and help avoid reproducing a gender bias. (shrink)

This paper revisits one of the most celebrated verses on dao and ming in the Opening Chapter of the received Laozi Daodejing. I shall clarify two types of English interpretations which are possibly applicable to the verse and demonstrate that they are equally sustainable. It follows that a commitment to either one of these interpretations may thereby spoil the meta-perspective effect which the verse skillfully creates.

Extending techniques of Dowd and those of Poizat, we study computational complexity of in the case when is a generic oracle, where is a positive integer, and denotes the collection of all -query tautologies with respect to an oracle . We introduce the notion of ceiling-generic oracles, as a generalization of Dowd's notion of -generic oracles to arbitrary finitely testable arithmetical predicates. We study how existence of ceiling-generic oracles affects behavior of a generic oracle, by which we show that is (...) not a subset of is comeager in the Cantor space. Moreover, using ceiling-generic oracles, we present an alternative proof of the fact (Dowd) that the class of all -generic oracles has Lebesgue measure zero. (shrink)

Shehtman and Skvortsov introduced Kripke bundles as semantics of non-classical first-order predicate logics. We show the structural equivalence between Kripke bundles for intermediate predicate lógics and Kripke-type frames for intuitionistic modal propositional logics. This equivalence enables us to develop the semantical study of relations between intermediate predicate logics and intuitionistic modal propositional logics. New examples of modal counterparts of intermediate predicate logics are given.

Since sending explicit messages can be costly, people often utilize “what is not said,” i.e., informative silence, to economize communication. This paper studies the efficient communication rule, which is fully informative while minimizing the use of explicit messages, in cooperative environments. It is shown that when the notion of context is defined as the finest mutually self-evident event that contains the current state, the efficient use of informative silence exhibits the defining property of indexicals in natural languages. While the efficient (...) use of silence could be complex, it is also found that the efficient use of silence can be as “simple” as the use of indexicals in natural languages if and only if the information structure satisfies some centrality and dominance properties.

This note is a continuation of our former paper ''Complexity of the r-query tautologies in the presence of a generic oracle.'' We give a very short direct proof of the nonexistence of t-generic oracles, a result obtained first by Dowd. We also reconstitute a proof of Dowd's result that the class of all r-generic oracles in his sense has Lebesgue measure one.

The economy and global competitiveness are the bottom line for society and governments, or so says conventional wisdom. But what are the real needs that must be satisfied to live rich, fulfilling lives? This is the question David Suzuki explores in this wide-ranging study. Suzuki begins by presenting the concept of people as creatures of the Earth who depend on its gifts of air, water, soil, and sun energy. He shows how people are genetically programmed for the company (...) of other species, and suffer enormously when we fail to live in harmony with them. And he analyzes those deep spiritual needs, rooted in nature, that are also a crucial component of a loving world. Drawing on his own experiences and those of others who have put their beliefs into action, "The Sacred Balance" is a powerful, passionate book with concrete suggestions for creating an ecologically sustainable, satisfying, and fair future by rediscovering and addressing humanity' s basic needs.

ResumoO texto aqui apresentado pretende dar uma pequena contribuição à discussão sobre a relação entre lógicae ontologia na filosofia kantiana. Seu objetivo é mostrar como Kant segue a lógica dos wolffianos, mantendosua abordagem geral, não sem introduzir algumas mudanças importantes. Ao contrário dos filósofosdogmáticos, Kant, como se sabe, enfatiza a neutralidade ontológica e epistemológica da lógica geral, diferenciando-a da lógica transcendental, que apresenta as condições universais necessárias apenas com basenas quais se pode falar de conhecimento objetivo. Leibniz, Wolff e seus (...) seguidores teriam negligenciadoessa distinção e dado à lógica geral um significado ontológico e heurístico, que absolutamente não lhepertence. Este artigo examina até que ponto essa versão da lógica dogmática, tão bem construída por Kante geralmente aceita pelos estudiosos, é confiável; tenta também mostrar que Kant flerta aqui e ali comasserções ontológicas e, ao fazê-lo, sua lógica também funciona como uma heurística. Os juízos categóricoe hipotético, bem como seus respectivos silogismos, serão aqui examinados em sua relação recíproca comocasos emblemáticos desse uso menos neutro da lógica formal por Kant. Além disso, espera-se que esteexame revele alguns dos procedimentos metódicos seguidos pelo filósofo em sua investigação conceitual,modo de proceder que, embora respeitando estritamente as regras lógicas estabelecidas, introduz modulaçõesdentro dessas mesmas regras, para enfrentar os desafios do pensamento crítico.Palavras-chave: Kant, lógica, ontologiaAbstractThe text presented here intends to make a small contribution to the discussion on the relationship betweenlogic and ontology in Kantian philosophy. Its purpose is to show how Kant follows the logic of theWolffians, maintaining their general approach, not without introducing some important changes. Unlikedogmatic philosophers, Kant, as is well known, lays stress on the ontological and epistemological neutralityof general logic, differentiating it from transcendental logic, which presents the necessary universal conditionsonly on the basis of which one can speak of objective knowledge. Leibniz, Wolff and his followerswould have neglected this distinction and given general logic an ontological and heuristic meaning, whichabsolutely does not belong to it. This article examines to what extent this version of dogmatic logic, so wellconstructed by Kant and generally accepted by the scholars, is reliable; it also tries to show that Kant flirtshere and there with ontological assertions and, in doing so, his logic also functions as a heuristic. The categoricaland the hypothetical judgments, as well as their respective syllogisms, will be examined here in theirreciprocal relationship as emblematic cases of this less neutral use of formal logic by Kant. Furthermore, thisexamination will hopefully reveal some of the methodical procedures followed by the philosopher in hisconceptual investigation, a way of proceeding that, although strictly respecting the established logical rules,introduces modulations within these same rules, to face the challenges of the critical thought.

Robustness against strategic manipulation is a crucial topic in social choice theory. Under some social ranking solutions (SRSs), namely mappings that yield candidates’ ranking from their coalitions’ ranking, candidates can sometimes improve their own social ranking by strategically degrading the coalitions to which they belong (e.g., sabotaging the coalitions to which the candidates and their competitors both belong could damage their competitors’ social rankings). This study investigates SRSs that can prevent such sabotage and promote sincere cooperation between candidates. To this (...) end, we introduce two axioms of SRSs by modifying the non-manipulability (NM) in the literature. An SRS is sabotage-proof (SP) if no candidate can improve their social ranking against anyone else through sabotage, and it is strongly sabotage-proof (SSP) if it is SP and is endowed with a sanction system against specific sabotage. We first demonstrate that the ceteris paribus majority (when there are at least four candidates) and lexicographic excellence solutions are SP but not SSP. We then propose a new characterization of dual lexicographic excellence solution as the unique linear SRS satisfying SSP and coalitional anonymity. Our axiomatic study provides a theoretical ground that lexicographic evaluation of coalitional performances is highly robust against strategic sabotage. (shrink)

Wabi Sabi is the Japanese Zen philosophy that all things are imperfect, unfinished and impermanent. It is a fresh way of seeing and moving through the world when our lives, literally and figuratively, feel cluttered. This book shows us how to apply this concept in the context of daily life and offers ideas on how to see it, embrace it and incorporate it into everyday thoughts, objects and situations."--Publisher description.

When an agent’s motivation is sensitive to how his supervisor thinks about the agent’s competence, the supervisor has to take into account both informational and expressive contents of her message to the agent. This paper shows that the supervisor can credibly express her trust in the agent’s ability only by being un- clear about what to do. Suggesting what to do, i.e., “directives,” could reveal the supervisor’s “distrust” and reduce the agent’s equilibrium effort level even though it provides useful information (...) about the decision environment. There is also an equilibrium in which directives are neutral in expressive content. However, it is shown that neologism proofness favors equilibria in which directives are double- edged swords.

Zen and Japanese Culture is one of the twentieth century's leading works on Zen, and a valuable source for those wishing to understand its concepts in the context of Japanese life and art. In simple, often poetic, language, Daisetz Suzuki describes his conception of Zen and its historical evolution. He connects Zen to the philosophy of the samurai, and subtly portrays the relationship between Zen and swordsmanship, haiku, tea ceremonies, and the Japanese love of nature. Suzuki's contemplative work (...) is enhanced by anecdotes, poetry, and illustrations showing silk screens, calligraphy, and examples of architecture. Since its original publication in 1938, this important work has played a major role in shaping conceptions of Zen's influence on Japanese traditional arts. Richard Jaffe's introduction acquaints a new generation of readers with Suzuki's life and career in both Japan and America. Jaffe discusses how Zen and Japanese Culture was received upon its first publication and analyzes the book in light of contemporary criticism, especially by scholars of Japanese Buddhism. (shrink)

The gap between the Markov blanket and ontological boundaries arises from the former's inability to capture the dynamic process through which biological and cognitive agents actively generate their own boundaries with the environment. Active inference in the free-energy principle (FEP) framework presupposes the existence of a Markov blanket, but it is not a process that actively generates the latter.

In this paper, we extend the canonicity methodology in Ghilardi & Meloni (1997) to arbitrary lattice expansions, and syntactically describe canonical inequalities for lattice expansions consisting of -meet preserving operations, -multiplicative operations, adjoint pairs, and constants. This approach gives us a uniform account of canonicity for substructural and lattice-based logics. Our method not only covers existing results, but also systematically accounts for many canonical inequalities containing nonsmooth additive and multiplicative uniform operations. Furthermore, we compare our technique with the approach in (...) Dunn et al. (2005) and Gehrke et al. (2005). (shrink)

A decision maker (DM) selects a project from a set of alternatives with uncertain productivity. After the choice, she observes a signal about productivity and decides how much effort to put in. This paper analyzes the optimal decision problem of the DM who rationally filters information to deal with her post-decision cognitive dissonance. It is shown that the optimal effort level for a project can be affected by unchosen projects in her choice set, and the nature of the choice set-dependence (...) is determined by the signal structure. Some comparative statics of choice set-dependence is also provided. Finally, based on the results, the optimal choice set design is also explored. This paper offers a simple framework to explain the experimental finding in psychology that people’s effort level for a project can be enhanced when the project is chosen by themselves rather than by others.

In a reenactment, a speaker re-presents or depicts a previously occurring event, often dramatically. In this article we examine the role of gaze in reenactments in conversations from Japanese and American English. Following Goodwin in viewing a reenacted story as ‘a multi-modal, multi-party field of activity’, we show how tellers’ and recipients’ gaze during reenactments is deployed to achieve specific interactional ends. We argue that there are two layers of activities involved in doing reenacting – a) the habitat of the (...) original event; b) the habitat of the reenacting event, including the dynamics of gaining appreciative recipiency – and show how they are interwoven in the joint production of a reenactment.
