Minka - The houses of Japanese imigrants in Ribeira valley, São Paulo,Brazil

O artigo analisa o processo de produção de moradia do imigrante japonês no Vale do Ribeira, na região sul do estado de São Paulo, ocorrido no início do século XX. Partindo do contexto histórico do início da colonização da região e as condicionantes que possibilitaram a criação da colônia, o trabalho busca verificar como foram construídas as casas que, baseados na autoconstrução e tendo a terra e madeira formaram o repertório de quase 500 casas. Põe foco em dois exemplares onde são analisadas a técnica do tsuchikabe e as sambladuras; verificando que mesmo diante das adversidades encontradas na natureza distinta de sua origem construíram casas de elevada qualidade. Os saberes trazidos do extremo oriente foram aplicados e se mesclaram às influências, cabocla, quilombola e europeia que hoje, após um século, representam uma categoria expressiva e variada sob os aspectos construtivo, tipológico e programático.

The alternative Pharaoh approach: stingless bees mummify beetle parasites alive

Workers from social insect colonies use different defence strategies to combat invaders. Nevertheless, some parasitic species are able to bypass colony defences. In particular, some beetle nest invaders cannot be killed or removed by workers of social bees, thus creating the need for alternative social defence strategies to ensure colony survival. Here we show, using diagnostic radioentomology, that stingless bee workers (Trigona carbonaria) immediately mummify invading adult small hive beetles (Aethina tumida) alive by coating them with a mixture of resin, wax and mud, thereby preventing severe damage to the colony. In sharp contrast to the responses of honeybee and bumblebee colonies, the rapid live mummification strategy of T. carbonaria effectively prevents beetle advancements and removes their ability to reproduce. The convergent evolution of mummification in stingless bees and encapsulation in honeybees is another striking example of co-evolution between insect societies and their parasites.

The role of olfactory cues in the sequential radiation of a gall-boring beetle, Mordellistena convicta

1. Herbivorous insects often have close associations with specific host plants, and their preferences for mating and ovipositing on a specific host-plant species can reproductively isolate populations, facilitating ecological speciation. Volatile emissions from host plants can play a major role in assisting herbivores to locate their natal host plants and thus facilitate assortative mating and host-specific oviposition. 2. The present study investigated the role of host-plant volatiles in host fidelity and oviposition preference of the gall-boring, inquiline beetle, Mordellistena convicta LeConte (Coleoptera: Mordellidae), using Y-tube olfactometers. Previous studies suggest that the gall-boring beetle is undergoing sequential host-associated divergence by utilising the resources that are created by the diverging populations of the gall fly, Eurosta solidaginis Fitch (Diptera: Tephritidae), which induces galls on the stems of goldenrods including Solidago altissima L. (Asteraceae) and Solidago gigantea Ait. 3. Our results show that M. convicta adults are attracted to galls on their natal host plant, avoid the alternate host galls, and do not respond to volatile emissions from their host-plant stems. 4. These findings suggest that the gall-boring beetles can orient to the volatile chemicals from host galls, and that beetles can use them to identify suitable sites for mating and/or oviposition. Host-associated mating and oviposition likely play a role in the sequential radiation of the gall-boring beetle.

Parameters of Reform and Unification in Modern Japanese Buddhist Thought: Murakami Senshō and Critical Buddhism

Reform is a word that, one might easily say, characterizes more than any other the history and development of Buddhism. Yet, it must also be said that reform movements in East Asian Buddhism have often taken on another goal—harmony or unification; that is, a desire not only to reconstruct a more worthy form of Buddhism, but to simultaneously bring together all existing forms under a single banner, in theory if not in practice. This paper explores some of the tensions between the desire for reform and the quest for harmony in modern Japanese Buddhism thought, by comparing two developments: the late 19th century movement towards ‘New Buddhism’ (shin Bukkyō) as exemplified by Murakami Senshō 村上専精 (1851–1929), and the late 20th century movement known as ‘Critical Buddhism’ (hihan Bukkyō), as found in the works of Matsumoto Shirō 松本史朗 and Hakamaya Noriaki 袴谷憲昭. In all that has been written about Critical Buddhism, in both Japanese and English, very little attention has been paid to the place of the movement within the larger traditions of Japanese Buddhist reform. Here I reconsider Critical Buddhism in relation to the concerns of the previous, much larger trends towards Buddhist reform that emerged almost exactly 100 years previous—the so-called shin Bukkyō or New Buddhism of the late-Meiji era. Shin Bukkyō is a catch-all term that includes the various writings and activities of Inoue Enryō, Shaku Sōen, and Kiyozawa Manshi, as well as the so-called Daijō-hibussetsuron, a broad term used (often critically) to describe Buddhist writers who suggested that Mahāyāna Buddhism is not, in fact, the Buddhism taught by the ‘historical’ Buddha Śākyamuni. Of these, I will make a few general remarks about Daijō-hibusseturon, before turning attention more specifically to the work of Murakami Senshō, in order to flesh out some of the similarities and differences between his attempt to construct a ‘unified Buddhism’ and the work of his late-20th century avatars, the Critical Buddhists. Though a number of their aims and ideas overlap, I argue that there remain fundamental differences with respect to the ultimate purposes of Buddhist reform. This issue hinges on the implications of key terms such as ‘unity’ and ‘harmony’ as well as the way doctrinal history is categorized and understood, but it also relates to issues of ideology and the use and abuse of Buddhist doctrines in 20th-century politics.

The Pursuit of Tangible Happiness: Religion and Politics in a Japanese New, New Religion

The decline of traditional religions in Japan in the past century, and especially since the end of World War Two, has led to an explosion of so-called “new religions” (shin shūkyō 新宗教), many of which have made forays into the political realm. The best known—and most controversial—example of a “political” new religion is Sōka Gakkai 創価学会, a lay Buddhist movement originally associated with the Nichiren sect that in the 1960s gave birth to a new political party, Komeitō 公明党 (lit., Clean Government Party), which in the past several decades has emerged as the third most popular party in Japan (as New Komeitō). Since the 1980s, Japan has also seen the emergence of so-called “new, new religions” (shin shin shūkyō 新新宗教), which tend to be more technologically savvy and less socially concerned (and, in the eyes of critics, more akin to “cults” than the earlier new religions). One new, new religion known as Kōfuku-no-Kagaku 幸福の科学 (lit., Institute for Research in Human Happiness or simply Happy Science), founded in 1986 by Ōkawa Ryūho 大川隆法, has very recently developed its own political party, Kōfuku Jitsugentō 幸福実現党 (The Realization of Happiness Party). This article will analyse the political ideals of Kōfuku Jitsugentō in relation to its religious teachings, in an attempt to situate the movement within the broader tradition of religio-political syncretism in Japan. In particular, it will examine the recent “manifesto” of Kōfuku Jitsugentō in relation to those of New Komeitō and “secular” political parties such as the Liberal Democratic Party (Jimintō 自民党) and the Democratic Party (Minshutō 民主党).

Beyond Belief: Japanese Approaches to the Meaning of Religion

For several centuries, Japanese scholars have argued that their nation’s culture—including its language, religion and ways of thinking—is somehow unique. The darker side of this rhetoric, sometimes known by the English term “Japanism” (nihon-jinron), played no small role in the nationalist fervor of the late-nineteenth and early twentieth centuries. While much of the so-called “ideology of Japanese uniqueness” can be dismissed, in terms of the Japanese approach to “religion,” there may be something to it. This paper highlights some distinctive—if not entirely unique—features of the way religion has been categorized and understood in Japanese tradition, contrasting these with Western (i.e., Abrahamic), and to a lesser extent Indian and Chinese understandings. Particular attention is given to the priority of praxis over belief in the Japanese religious context. Des siècles durant, des chercheurs japonais ont soutenu que leur culture – soit leur langue, leur religion et leurs façons de penser – était en quelque sorte unique. Or, sous son jour le plus sombre, cette rhétorique, parfois désignée du terme de « japonisme » (nihon-jinron), ne fut pas sans jouer un rôle déterminant dans la montée de la ferveur nationaliste à la fin du XIXe siècle, ainsi qu’au début du XXe siècle. Bien que l’on puisse discréditer pour l’essentiel cette soi-disant « idéologie de l’unicité japonaise », la conception nippone de la « religion » constitue, quant à elle, un objet d’analyse des plus utiles et pertinents. Cet article met en évidence quelques caractéristiques, sinon uniques du moins distinctives, de la manière dont la religion a été élaborée et comprise au sein de la tradition japonaise, pour ensuite les constrater avec les conceptions occidentale (abrahamique) et, dans une moindre mesure, indienne et chinoise. Une attention toute particulière est ici accordée à la praxis plutôt qu’à la croyance dans le contexte religieux japonais.

Revisioning a Japanese Spiritual Recovery Through Manga: Kobayashi Yoshinori’s ‘Gōmanism’ as Aesthetics and Ideology

This essay provides a critical analysis of the aesthetic ideology of “Gomanism” in the manga of Kobayashi Yoshinori (b. 1953), particularly Yasukuniron (On Yasukuni, 2005) and Tennōron (On the Emperor, 2009), in order to flesh out the implications of the author’s “revisionist” approach to Japanese religion, politics and history.

Inbreeding and selection on sex ratio in the bark beetle Xylosandrus germanus

Background Local Mate Competition (LMC) theory predicts a female should produce a more female-biased sex ratio if her sons compete with each other for mates. Because it provides quantitative predictions that can be experimentally tested, LMC is a textbook example of the predictive power of evolutionary theory. A limitation of many earlier studies in the field is that the population structure and mating system of the studied species are often estimated only indirectly. Here we use microsatellites to characterize the levels of inbreeding of the bark beetle Xylosandrus germanus, a species where the level of LMC is expected to be high. Results For three populations studied, genetic variation for our genetic markers was very low, indicative of an extremely high level of inbreeding (FIS = 0.88). There was also strong linkage disequilibrium between microsatellite loci and a very strong genetic differentiation between populations. The data suggest that matings among non-siblings are very rare (3%), although sex ratios from X. germanus in both the field and the laboratory have suggested more matings between non-sibs, and so less intense LMC. Conclusions Our results confirm that caution is needed when inferring mating systems from sex ratio data, especially when a lack of biological detail means the use of overly simple forms of the model of interest.
