Japan's diplomatic codes were broken by the Soviet Union in the late 1930s. This was due to Kōzō Izumi (1890-1956), a Japanese diplomat and Soviet specialist stationed in Eastern Europe, who provided ...Japan's code books and keys to the Soviet secret police. Married to a Muscovite of noble origin working for the Soviet Foreign Intelligence, Izumi was entrapped and ultimately chose love over country. He thus led an unwitting Japan to conduct 'open diplomacy' towards the Soviet Union.
Many landslides were induced by the heavy rainfall of Typhoons 0415 and 0421 in Niihama city, east Ehime prefecture. Detailed geomorphic analysis by using airborne laser scanner and geologic ...investigation revealed the geomorphic and geologic features of landslide sites. The affected area is underlain by the Cretaceous Izumi Group consisting of alternating beds of sandstone, mudstone, and granule conglomerate; the Izumi Group had been supposed to be not susceptible to shallow landslides by rainstorms. Landslide sites were not controlled by lithology but were controlled by the intensity of weathering: the most common landslides were shallow slides of a soil layer derived from heavily weathered rocks. Airborne laser scanner detected landslides of 2004 and of previous years and convex slope breaks. Landslide crowns are aligned laterally to form convex slope breaks, which are "denudation front": Slopes just above these denudation fronts and on heavily weathered rocks are the most susceptible slopes to rainstorms.
The heteromorph ammonite Pravitoceras sigmoidale from the Upper Cretaceous Seidan Formation (Izumi Group) in south‐west Japan is frequently encrusted by sessile anomiid bivalves. Fossils of ...P. sigmoidale with anomiids are often concentrated at the top of or just above turbidite sandstones. Projecting retroversal hooks and apertures of P. sigmoidale are usually intact, and some individuals are associated with jaw apparatuses near apertures. Anomiids are found on both sides and ventral peripheries of P. sigmoidale conchs, attached predominantly to body chambers. These modes of occurrence suggest that the encrustation by anomiids occurred not on post‐mortem floating or sunken carcasses but on live conchs and that these organisms were rapidly buried by turbidity current deposits shortly after death. Attachment to both flanks and ventral peripheries of the retroversal hooks may indicate that at least adult individuals of P. sigmoidale did not lie on the sea floor and did not drag their body chambers. It is suggested that fully mature individuals of this ammonite species lived for a long period of time after having formed the retroversal hook because a few generations of anomiids have colonized a single body chamber. Such colonization by anomiids is also observed on Didymoceras awajiense, which is considered to be the closely related ancestral species of P. sigmoidale. This anomiid–heteromorph ammonite commensal relationship might continue to persist in descendants during the course of evolution of these heteromorph ammonites.
The heteromorph ammonite Pravitoceras sigmoidale Yabe, of the family Nostoceratidae, is the zonal marker of the upper Campanian P. sigmoidale Zone in southwest Japan, and is the main component of ...ammonite assemblages in this zone. We explain the taphonomic processes underlying the occurrence of P. sigmoidale in the Izumi Group, specifically in the Minato (Awaji Island), Anaga (Awaji Island), Koike–Omoizaki (Shikoku), and Hidonodani sections (Shikoku). The first two sections consist mainly of the non-turbiditic Northern Marginal Facies (NMF), while the latter two sections comprise the Main Facies (MF), a turbiditic facies deposited in waters deeper than those of the NMF. We recognise three modes of occurrence of P. sigmoidale, as follows: (1) In nodules crowded with P. sigmoidale (NCP); this mode occurs only in the NMF, and includes juvenile and adult specimens, together with other ammonites such as Solenoceras (Oxybeloceras) aff. humei (Douvillé), (2) In mudstone with isolated P. sigmoidale (MIP), which is found in all of the sections studied, (3) In sandstone with isolated P. sigmoidale (SIP), which occurs only in the MF. Adult individuals of P. sigmoidale are dominant in most of the sections, while juveniles were observed only in the Minato section, which originally was closer to land areas. The number of specimens of P. sigmoidale and Solenoceras spp. tends to increase in sections representing depositional environments proximal to terrestrial areas. Ammonite assemblages could have been transported from shallow- to deep-water settings by turbidity currents. The sorting of components by transport processes likely contributed to the formation of these fossil assemblages in different areas. This is an important clue to understanding the habitat of heteromorph ammonite life assemblages consisting mainly of P. sigmoidale.
•Taphonomic processes and habitat of heteromorph ammonite Pravitoceras sigmoidale Yabe.•Three modes of occurrence of P. sigmoidale are observed in the Izumi Group.•Fossil assemblages were transported by turbidity currents.•Ammonite life assemblages existed in northern marginal part of the basin.
Well-preserved upper and lower jaws of the aptychus-type found inside the body chambers of two specimens of the heteromorph ammonoid Pravitoceras sigmoidale Yabe, 1902 (Nostoceratidae, ...Ancyloceratina) are described from the Upper Cretaceous Izumi Group in Southwest Japan. They are similar in overall morphology to those of other nostoceratid and diplomoceratid ammonoids currently known, suggesting the morphological stability of the jaw features among these taxa. The equal size of the upper and lower jaws with beak-like rostral projection suggests that the jaw apparatus of this species might function to bite and cut up prey.
In my paper I intend to focus on Izumi Kyõka's "A Map of Shirogane", analyzing the way actual places and architectural structures are described through the eyes of the main character, the old kyõgen ...actor Hagiwara Yogorõ, who goes to Shirogane to look for Omachi, a girl whom he had previously met and who he thinks will help him play his roles more convincingly. A central place in the economy of the novel is taken by the University of the Sacred Heart (Seishin Joshi Gakuin), which was built in the western architectural style in 1910. As sites for acquiring advanced western learning, many colleges had been built in the western style since the beginning of the Meiji period, so in that sense there is nothing particularly new or remarkable about the structure of the University of the Sacred Heart. Rather, what is remarkable is the way in which the old man gradually comes to see it as two overlapping images: a western architectural structure, and an Inari torii (site of reverence of the fox deity since ancient times). His viewpoint might symbolize the gradually changing face of Shirogane, where the quiet residential site of a samurai family's villa is transformed by the construction of a university. Through the detailed analysis of the images of the places and buildings described in the novel, I will attempt to clarify the way Kyoka articulated the consciousness of the people living in these changing spaces and went on to create a unique world of his own. PUBLICATION ABSTRACT
Seven species of decapods are described from the Izumi Group (Upper Cretaceous: Campanian–Maastrichtian) of Hyogo and Osaka Prefectures, central Japan. Archaeopidae, a new family of Retroplumoidea ...embraces the monotypic Late Cretaceous genus Archaeopus. Hinecaris simplex, a new genus and species is the first record for the axiidean family Axiidae from the Cretaceous rocks of Japan. “Callianassa” (s.l.) masanorii Karasawa, 1998, is re-described and is moved from Callianassidae to Gourretiidae. A re-description is given for Linuparus japonicus Nagao, 1931, and Archaeopus ezoensis (Nagao, 1941). The lectotype for Linuparus japonicus Nagao, 1931, is herein designated.
On the eve of deinstitutionalization, a group of professionals, including an architect, a psychiatrist, and a psychologist, joined together in pursuit of a middle ground between outright closure of ...long-stay hospitals and the introduction of out-patient services in general hospitals. Augmented by the use of the hallucinogenic drug LSD, these men produced a trenchant critique of modern psychiatry and the changing mental health system without subscribing to antipsychiatry. Caught among shifting psychiatric paradigms, fiscal constraints, and political pressure to situate mental health within an encroaching system of publicly funded health care reforms, their proposed mental hospital designs failed to stem the tidal wave of post-World War II changes in mental health care.
