‘Gender ’ is a troublesome loanword in Japan. While this term has been prevalent in feminist and scholarly circles, it has evoked confusion in the government and stimulated a backlash from the ultra-conservatives against gender equality. Japanese reactionaries have attacked the concept of gender because of their anxiety about cultural destruction – I thus call them the ‘old guard’. Focusing on a dispute over the term ‘gender’ between feminists and the old guard, this paper examines the changes in the term's (...) usage and meanings in the Japanese political context. I first shed light on Japan's reaction to the newly arrived term ‘gender’, outlining different attitudes towards gender between the feminist/scholarly circles and the government. Secondly, I discuss the old guard's condemnation of the concept of gender, in which they distort its significance in order to diminish its positive impact on society. I then scrutinize the old guard's reasons behind their attack on the concept of gender. My findings reveal that the old guard, whose political cause is to protect traditional Japanese culture, asserts that gender equality damages this culture. Moreover, I refute their emphasis on Japan's uniqueness, demonstrating that Japanese women's traditional virtues under the patriarchal family system are not peculiar to Japan. To gauge how the concept of gender has been interpreted politically, I highlight legislative debates about the term ‘gender’. In doing so, I elucidate the extent to which the concept of gender has infiltrated Japanese society through the dispute.Export citation Request permission. (shrink)

We used a response competition paradigm to investigate whether a distractor is effectively rejected under conditions where it is projected to a highly-loaded hemisphere. In two experiments we asked right-handed participants to identify a target among five task-relevant letters while they ignored a distractor. We manipulated both the distractor visual-field and the compatibility of the target and the distractor. In the low-loaded visual-field, we presented a distractor with one task-relevant stimulus to one visual-field and the remaining task-relevant stimuli to the (...) opposite visual-field. In the high-loaded visual-field, we presented a distractor and task-relevant stimuli in reverse. In Experiment 1 , we found a compatibility effect for the low-loaded, but not for the high-loaded visual-field. In Experiment 2, this modulation of the compatibility effect did not appear when the upper/lower visual-field was manipulated. These findings demonstrate that a distractor is successfully ignored when it is presented to a highly-loaded hemisphere. (shrink)

When the Argonauts reach the island of Lemnos, Apollonius of Rhodes tells us, they send their herald Aethalides to the ruler of the island. Such a means of establishing contact and requesting safe passage was the norm in the Homeric world; there heralds acted as intermediaries between commanders and subordinates or between groups of people. In preliterate societies, heralds facilitated communication: messages were transmitted through memorization and repetition rather than by means of writing. While verbatim repetition was no doubt a (...) necessary feature of this form of communication, its wholesale transference into Homeric poetry was not necessarily the logical corollary. Nonetheless, we know of such repetitions precisely because of their appearance in the Homeric poems. It is now widely accepted that such passages are a result of the oral style of composition in which the oral poet repeats passages just as he uses shorter formulaic phrases. The debate embedded in the A-scholia of the Iliad suggests that repeated passages were a source of contention already in antiquity. While it is more common to see the scholiasts trying to decide which passage is ‘correct’ and which should be athetized, this provides evidence that athetization was not a unanimous impulse. The scholiast defends 2.60–71, part of which is repeated for the third time, against Zenodotus. (shrink)

Graphical AbstractEnvironmental oxygen might have been the key for the evolution of novel developmental mechanisms, such as the interdigital cell death of amniotes. Increased amount of oxygen can also induce cell death in interdigital regions of an amphibian that typically lacks it. To learn more about the role of environmental oxygen in the evolution of new traits, see the article number 2000025 by Ingrid Rosenburg Cordeiro and Mikiko Tanaka.

The PIWI-interacting RNA pathway, one of the major eukaryotic small RNA silencing pathways, is a genome surveillance system that silences selfish genes in animal gonads. piRNAs guide PIWI protein to target genes through Watson–Crick RNA–RNA base-parings. Loss of piRNA function causes genome instability, inducing failure in gametogenesis and infertility. Studies using fruit flies and mice as key experimental models have resulted in tremendous progress in understanding the mechanism underlying the piRNA pathway. Recent work using cultured silkworm germline cells has also (...) expanded our knowledge of piRNA biogenesis in particular, since these silkworm cells are the only cells of germline origin that can be cultured. In this review, we describe elucidation of the piRNA pathway using cultured silkworm cells as an experimental model by focusing on recent work in biochemistry and structural biology. Earlier studies that made important contributions to the field are also described. PIWI-interacting RNAs are germline-enriched small RNAs that silence transposons to maintain genome integrity. Recently, cultured silkworm germline cells such as BmN4 made great contributions to understand the mechanism underlying piRNA biogenesis in particular. In this review, we highlight the recent progress in biochemical and structural biology. (shrink)

In conventional generalization of the main results of classical measure theory to Stone algebra valued measures, the values that measures and functions can take are Booleanized, while the classical notion of a σ-field is retained. The main purpose of this paper is to show by abundace of illustrations that if we agree to Booleanize the notion of a σ-field as well, then all the glorious legacy of classical measure theory is preserved completely.

By creating an unbounded topological reduction theory for complex Hilbert spaces over Stonean spaces, we can give a category-theoretic duality between Boolean valued analysis and topological reduction theory for complex Hilbert spaces. MSC: 03C90, 03E40, 06E15, 46M99.

Oxygen is a key regulator of both development and homeostasis and a promising candidate to bridge the influence of the environment and the evolution of new traits. To clarify the various ways in which oxygen may modulate embryogenesis, its effects are reviewed at distinct organizational levels. First, the role of pathways that sense dioxygen levels and reactive oxygen species are reviewed. Then, the effects of microenvironmental oxygen on metabolism, stemness, and differentiation throughout embryogenesis are discussed. Last, the interplay between ecology (...) and development are reexamined with a focus on the evolution of tetrapods, including during the emergence of a novel mechanism that shapes amniote limbs—interdigital cell death. Both genetic and environmental components work together during the formation of organisms, highlighting the importance of a multidisciplinary approach for understanding the evolution of new traits.

Influential neoclassical economist Lionel McKenzie has made major contributions to postwar economic thought in the fields of equilibrium, trade, and capital accumulation. This selection of his papers traces the development of his thinking in these three crucial areas.McKenzie's early academic life took him to Duke, Princeton, Oxford, the University of Chicago, and the Cowles Commission. In 1957, he went to the University of Rochester to head the economics department there, and he remains at Rochester, now Wilson Professor Emeritus of Economics. (...) McKenzie's most significant research was undertaken during a period that saw the development of the major themes of neoclassical economics and the use of fundamental mathematical methods to do so. McKenzie contributed to both aspects of this research program. He helped shape the direction of the field and, at Rochester, influenced generations of future scholars. In 2002, The MIT Press published McKenzie's Classical General Equilibrium Theory, a detailed summary of the model and methodology. This book, collecting his most important papers in the form in which they were originally published, can be seen as a companion to that one. The many state-of-the-art results achieved in McKenzie's original papers present sophisticated theoretical work that will continue to be important to future developments in the discipline. (shrink)

In spite of the philosophical significance of higher-order modal logic, the modal logician's main concern has been with sentential logic. In this paper we do not intend to go into philosophical details, but we only remark that higher-order modal logic has a close relationship with Montague's well-known idea of “universal grammar”, which is an ambitious attempt to build a logical theory of natural languages with exact syntax and semantics, comparable with the artificial languages of mathematical logic. For this matter, the (...) reader can consult, e.g., Montague [8], [9] and Gallin [2]. (shrink)

The aims of this paper are: (1) to present tense-logical versions of such classical notions as saturated and special models; (2) to establish several fundamental existence theorems about these notions; (3) to apply these powerful techniques to tense complexity.In this paper we are concerned exclusively with quantifiedK 1 (for linear time) with constant domain. Our present research owes much to Bowen [2], Fine [5] and Gabbay [6].
