Sewall Wright and Gustave Malécot developed important theories of isolation by distance. Wright’s theory was statistical and Malécot’s probabilistic. Because of this mathematical difference, they were not clear about the relationship between their theories. In this paper, I make two points to clarify this relationship. First, I argue that Wright’s theory concerns what I call ecological isolation by distance , whereas Malécot’s concerns what I call genetic isolation by distance . Second, I suggest that if Wright’s theory is interpreted appropriately, (...) a previously unnoticed connection between the two theories emerges. †To contact the author, please write to: Yoichi Ishida, Department of History and Philosophy of Science, University of Pittsburgh, 1017 Cathedral of Learning, Pittsburgh, PA 15260; e‐mail: [email protected].

Stein has raised a fundamental problem for any attempt to characterize instrumentalism and realism as substantive alternatives. This is the distinguishability problem, which consists in the problem of developing a form of instrumentalism that is substantially different from a plausible realist alternative and the problem of showing that this form of instrumentalism does justice to actual scientific practice. Using Stein’s own discussion of Maxwell, I formulate instrumentalism and realism as a scientist’s attitudes toward models, where an attitude is understood to (...) be a complex of the scientist’s belief and intention regarding models. Developing a case study of Benzer’s modeling practice, I show that each attitude can structure inquiry differently and argue that to understand certain aspects of scientific practice, such as the practice of genetic mapping in Benzer’s work, we sometimes need to appeal to the coexistence of these attitudes.

Robert MacArthur's mathematical ecology is often regarded as ahistorical and has been criticized by historically oriented ecologists and philosophers for ignoring the importance of history. I clarify and defend his approach, especially his use of simple mathematical models to explain patterns in data and to generate predictions that stimulate empirical research. First I argue that it is misleading to call his approach ahistorical because it is not against historical explanation. Next I distinguish three kinds of criticism of his approach and (...) argue that his approach is compatible with the first two of them. Finally, I argue that the third kind of criticism, advanced by Kim Sterelny and Paul Griffiths, is largely irrelevant to MacArthur's approach. ‡I am especially grateful to Thomas Nickles for encouragement and helpful comments on earlier versions of this paper. Thanks also to Guy Hoelzer, Stephen Jenkins, and Jay Odenbaugh for comments on an earlier draft, Kim Sterelny for clarifications of the Tasmania example, Gregory Mikkelson for references, and the audience at PSA 2006 for discussions. †To contact the author, please write to: Department of History and Philosophy of Science, University of Pittsburgh, 1017 Cathedral of Learning, Pittsburgh, PA 15260; e-mail: [email protected].

Evolution is frequently concentrated in bursts of rapid morphological change and speciation followed by long‐term stasis. We propose that this pattern of punctuated equilibria results from an evolutionary tug‐of‐war between host genomes and transposable elements (TEs) mediated through the epigenome. According to this hypothesis, epigenetic regulatory mechanisms (RNA interference, DNA methylation and histone modifications) maintain stasis by suppressing TE mobilization. However, physiological stress, induced by climate change or invasion of new habitats, disrupts epigenetic regulation and unleashes TEs. With their capacity (...) to drive non‐adaptive host evolution, mobilized TEs can restructure the genome and displace populations from adaptive peaks, thus providing an escape from stasis and generating genetic innovations required for rapid diversification. This “epi‐transposon hypothesis” can not only explain macroevolutionary tempo and mode, but may also resolve other long‐standing controversies, such as Wright's shifting balance theory, Mayr's peripheral isolates model, and McClintock's view of genome restructuring as an adaptive response to challenge.

Indirect discrimination (or disparate impact) is one of the focal points of current antidiscrimination policies. However, few political/moral philosophers have paid substantial attention to indirect discrimination until recently. This contribution provides an overview of the two philosophical questions in this context: the definitional question (DQ) and the moral question (MQ). DQ concerns what distinguishes indirect discrimination from direct discrimination and inequality. Conceptually, either (1) indirect discrimination is not a genuine subtype of discrimination; (2) it is a subtype of discrimination secondary (...) to direct discrimination; or (3) it is a subtype of discrimination independent of direct discrimination. A more substantial distinction between direct and indirect discrimination can be drawn according to the discriminator’s intention, the disproportionateness of intergroup disadvantage, and so forth. MQ addresses what makes indirect discrimination morally wrong. Conceptually, either (1) indirect discrimination cannot be morally wrong qua discrimination in its own right; (2) it can be morally wrong qua discrimination in its own right, where the wrongness must be connected to past direct discrimination; or (3) it can be morally wrong qua discrimination regardless of past direct discrimination. Substantially, possible wrong-making factors of indirect discrimination include the discriminator’s objectionable intentions, the objectionable message that discriminatory practices may carry, and their harmful effects. This framework is a first step for future works that are necessary to yield a comprehensive insight into the relationship between discrimination and inequality and address contemporary forms of discrimination that tend to be indirect rather than direct.

This article conducts a decision theoretic analysis of the effect of dual candidacy on voting decisions in the Japanese variant of the mixed electoral system, where each candidate can run in both a single-member district (SMD) and a proportional representation (PR) block, and dual candidates can be ranked either individually or equally in parties' PR lists: their post-election ranking is determined by their SMD votes. The model shows that dual candidacy differentiates the mixed system from merely the simultaneous use of (...) the SMD and PR systems. That is, if an SMD candidate also runs in the PR block, it lowers voters' utility increment obtained by casting their SMD votes for him. If he is ranked equally in the PR list, however, SMD votes for him may help him win a PR seat against other equally ranked dual candidates, which enables dual candidacy accompanied by equal ranking to attract more SMD votes.

In lieu of an abstract, here is a brief excerpt of the content:Report on the Thirtieth Annual Conference of the Japan Society for Buddhist-Christian StudiesYagi YōichiTranslated by Paul L. SwansonIn Japan, the disasters of the giant tsunami and the resulting crisis at the Fukushima nuclear power plant on 11 March 2011 have been grim reminders of the unprecedented tragedies of the nuclear bombings on Hiroshima and Nagasaki just sixty-six years ago. These are experiences in which one becomes speechless, when words (...) are no longer able to convey what used to be their usual meaning.At that time, people were faced with basic and universal questions concerning the fundamental constitution of human existence. What is the ultimate basis for our thoughts and actions? Is there a way to know? If there is a way to know these answers, how do we attain them? The state of intellectual inquiry in postwar Japan, however, was not able to face these questions and come up with answers. Rather, there was a tendency to avoid facing these questions directly and instead rely on absorbing the pronouncements of Western thought.Within this postwar intellectual environment in Japan, the Japan Society for Buddhist- Christian Studies has continuously attempted in an academic way to discuss comprehensive themes, based on Buddhist-Christian or Christian-Buddhist foundations, and is perhaps the only forum in Japan that has consistently sought answers to these basic and universal questions of human existence.It was in this time of crisis that the thirtieth annual conference of the Japan Society for Buddhist-Christian Studies met 5-7 September 2011 at Hanazono University in Kyoto. Discussion of a recent book, Dialogue and Commentary: The Words of Jesus and the Words of Zen (対談評釈 イエスの言葉／ 禅の言葉, Iwanami Shoten, 2010, in Japanese), a series of dialogues and discussions between Ueda Shizuteru and Yagi Seiichi, was chosen as an appropriate theme for this meeting. This book was chosen because it is a splendid synthesis of the activity and discussion carried out by our Society over the past thirty years. Through the magnificent dialogue of these two men, we hoped to open a "living horizon" for a mutual understanding of "the words of Jesus and the words of Zen." The main themes were "direct experience," "self-awareness," "place," and "words."The two dialoguers—Ueda and Yagi—have not only both served and provided [End Page 139] leadership for the Society over many years, as presidents and in other capacities, but also share a basic sense of fundamental questions. They are also leading philosophers of religion who represent the attempt to seek answers to fundamental questions within Buddhism and Christianity in postwar Japan. Ueda Shizuteru, a leading authority and internationally recognized scholar of Meister Eckhart, is also known for his contributions on the philosophy of religion (especially the idea of "place"/basho) in the tradition of Nishida Kitarō, Nishitani Keiji, and Zen Buddhism. His basic philosophical statement is "I am I when I am not I." Yagi Seiichi, on the other hand, is known for promoting religion (philosophy) as "a logic of place" as seen in the New Testament, and for his historical and essentialist critique of New Testament thought. To Yagi, the essence of "the religion of Jesus" is religion as a "logic of place," and if we return to this place we can (to borrow the exquisite phrasing of Yagi himself) "drink directly from the same fountain that was discovered by Jesus." Through this experience we can transcend not only biblical fundamentalism and the exclusivist absolutism of Christianity, but also make it possible to have a true dialogue with other religions. For Yagi, the dialogue between Buddhism and Christianity not only should deepen common understanding, but also open the way to mutual reform, clarify the truth that flows at the basis of both religions, and probe into the fundamental constitution of human existence, and this is why he has constantly sought after dialogue with Buddhists.Yagi Seiichi has stood out as a partner in dialogue for many years. His discussions with the Zen master Hisamatsu Shin'ichi (A Religion of Awakening, published in 1980) was an epochal event in intellectual history from the perspective of "Buddhism and Christianity." Yagi has also been involved in important dialogues with Nishitani... (shrink)

Seit einiger Zeit mehren sich in der Fichte-Forschung die Versuche, Fichtes Philosophie aus ihrer Interpretation durch Hegel herauszulösen und damit ihre Eigenständigkeit neu sichtbar zu machen. Dabei wird u.a. die Auffassung vertreten, Hegel habe Fichte falsch oder zumindest einseitig verstanden, wenn er in seiner Differenzschrift oder in Glauben und Wissen dessen Philosophie als »Reflexionsphilosophie« oder »formalen Idealismus« bezeichnet. Dagegen gibt es Stimmen, die Hegels Interpretation Fichtes als gerechtfertigt verteidigen. Diese Diskussion verweist nicht nur auf Defizite in den philosophischen Theorien von (...) Fichte und Hegel, die nicht geleugnet werden können, sondern mehr noch darauf, dass es in den Standpunkten beider erhebliche Unterschiede gibt, die zunächst herausgearbeitet und bedacht werden müssen.

On March 16, 2020, the Director-General of the World Health Organization said: “We have a simple message to all countries—test, test, test.” This seems like sound advice, but what if limiting the number of tests has a positive effect on infection control? Although this may rarely be the case, the possibility raises an important ethical question that is closely related to a central tension between deontological and consequentialist approaches to ethics. In this paper, we first argue that early during the (...) COVID-19 pandemic, Japan offers an interesting case because it experienced few deaths due to COVID while the number of tests was limited, suggesting that there may be cases in which low testing contributes to infection control indeed. After that, we examine deontological constraints on such a “low-testing” policy, focusing on issues related to a supposed “right to know,” which is a central issue in medical ethics in general.

Understanding whether the long and elaborate songs of male gibbons have syntax and hierarchical structures is an interesting question in the evolution of language, because gibbons are near humans in the phylogenetic tree and a hierarchically organized syntax is considered to be a basic component of human language. We conducted field research at Danum Valley Conservation Area in northern Borneo to test the hypothesis that gibbon songs have syntax and chunks. We followed one Mueller’s gibbon group for 1 week in (...) the dry and rainy seasons every year from 2001 to 2009, collecting vocal and behavioral data. Results show that songs emitted by the studied male gibbon were governed by combinatory rules. Some context-dependent songs had different combinatory rules, although they overlapped with the songs whose contexts were uncertain. The male Mueller’s songs had characteristics that suggest existence of chunk structure. These results provided an important perspective in the study of language origin. (shrink)

The quantum efficiency (QE) of light-induced metastable defect creation in hydrogenated amorphous silicon (a-Si : H) and amorphous As2Se3 (a-As2Se3) by bandgap and subgap illumination has been deduced from photocurrent measurements. The QE decreases with increasing number of absorbed photons. A higher QE for a-As2Se3 than for a-Si : H has been observed and this is interpreted in terms of the higher structural flexibility of a-As2Se3. We have also found that, for both materials, subgap illumination yields a higher QE than (...) does bandgap illumination. (shrink)

Mueller's gibbons ( Hylobates muelleri ) sing both sex-specific and duet songs. These songs are thought to be involved in territory maintenance, as well as the maintenance of pair or family bonds. However, few observational studies have examined how gibbons interact with their neighbors through song in the wild. We have been conducting field observations of wild gibbon groups in northeast Borneo since 2001. In the Borneo Rainforest Lodge (BRL) and Danum Valley Field Center (DVFC) at the Danum Valley Conservation (...) Area (DVCA), we observed seven episodes of alternating songs between males. Here, we describe the process of song exchange between males. During male interactions, song bouts rarely overlapped and were alternately emitted. Several studies have reported antiphonal vocalizations in New World and Old World primate species, but rarely in apes. Our observations of antiphonal songs in gibbons indicate that gibbons not only unilaterally advertise information, but also interactively communicate with neighbors and family members through songs. Since gibbons are phylogenetically similar to humans, and turn-taking has an important role in human conversation, our research on gibbon communication may provide insight into the evolution of human language.

Mating activity of a wild Mueller’s gibbon group was observed in the Danum Valley Conservation Area, Sabah, Malaysia. The purpose of this study was to investigate the function of copulation calls in gibbons. The female emitted copulation calls at the time of intromission and pelvic thrusting. Copulation calls were composed of two notes and one of them was sung only while mating. Approximately half of copulation calls were sung near the range boundary. Mating with copulation calls sometimes occurred while singing. (...) According to the model that female copulation calls have evolved under the selective pressures of risk of infanticide and sperm competition, copulation calls should be rare in species with little female promiscuity. As gibbons usually live in pair-living social organization and have a monogamous mating system, no vocal signals by female gibbons are considered to be needed. However, clear copulation calls were emitted by the female. It suggests that the relationship between paired gibbons is unstable. Copulation calls by the female Mueller’s gibbon may function to increase mate guarding and strengthen the pair bond. (shrink)

The various schools of the Indian classical philosophy have discussed the issue how we understand the meaning from an utterance. In the present paper, I analyse the ancient controversy on this issue between two schools, Naiyāyikas and Vaiśeṣikas, and attempt to show that it has two aspects of religious and epistemological natures. Vaiśeṣikas, on the ground that the process of the verbal understanding is identical with that of the inference, claim that the verbal understanding is merely a type of the (...) inference. Naiyāyikas oppose this and assert that the former is distinct from the latter. I summarise Vaiśeṣikas’ argument into two points: (1) the similarity of the objects of the cognition and (2) that of the relations between the object and what denotes it. Naiyāyikas rejects both thesimilarities. The above discussion, which may stimulate our epistemological interest, has a close connection with the issue of scriptures. The utterance as a source of knowledge seems to have stood, in the early period, only for the scriptures, as pointed out by Hiryanna. Taking this into consideration, Vaiśeṣikas’ thesis can be understood to imply that they deny the intrinsic authority of scriptures and reduce it to the rational faculty of human beings. Naiyāyikas also deny itsintrinsic authority, but their view on the cognitive process of the verbal understanding is different from that of Vaiśeṣikas. The reason of this divergence may lie in how they treat the reliability of the speaker in respect to the cognitive process. (shrink)

The construct of Cognitive Moral Development (CMD) has drawn much attention in the study of business ethics for over two decades. The Defining Issues Test (DIT) has made a significant contribution to the literature as an easy-to-administer CMD instrument, and the Moral Judgment Test (MJT), an alternative scale, has also been used widely especially in Europe. The two scales differ in their approaches to measuring CMD, focusing on stage preference (DIT) and stage consistency (MJT), yet empirical comparisons have been scarce. (...) The present research empirically compares the two scales in terms of their correspondence with ethical ideology as a reference scale, and it demonstrates a clear distinction between the DIT and the MJT. Although they both aim to measure CMD, their dissimilar approaches lead to distinctly different implications. (shrink)
