Rivalry and cooperation: how the Japanese photographic industry went global
No full textThis thesis analyzes the postwar political economy of the global photography industry, i.e. camera/lens and film, up to 1995 and finds that the Japanese industry has met unprecedented success. The question addressed in this thesis is: who drove the success of the Japanese photography industry, the government or firms? The words 'rivalry' and 'cooperation' are used in this thesis because they most aptly describe the three main relationships in the photography industry during the postwar period: bureaucrat-politician, government-industry and firm-firm. Cooperation and rivalry always existed in these relationships, but one often took precedence over the other.
The camera/lens makers in Japan's photography industry benefited from cooperative relationships through export promotion and import protection policies from 1950 to 1973. Export promotion was effective because Japanese camera/lens firms began to 'export' to US military postal exchanges in Japan during the Allied Occupation (1945-1952). After that time, the US market was wide open to Japanese exports due to Japan's balance of payments problems and America's mounting security concerns in Asia. Exports of cameras/lenses to the US and Europe expanded throughout the 1950s and 1960s, while photographic film manufacturers (who also produced cameras/lenses) caught up technologically and enjoyed a protected domestic market for film. After 1974, rivalry increased in the three main relationships primarily due to changes in the international trading regime and within Japan. In particular, firm-firm rivalry in cameras/lenses and film grew throughout the 1970s and intensified during the 1980s as new technological advances raised the stakes for global market shares.
This thesis shows that some firms have been successful despite government involvement in the industry, while others have been successful because of it. Cooperation between the government and industry was important in the early years because of the tight controls placed on industry (up to the early 1970s). But the influence of the government waned as the firms within the photography industry went global and rivalry among firms increased. Additional sectoral studies of Japan's early export industries (e.g. sewing machines, bicycles, clocks/watches) are needed to provide additional evidence of the extent to which there was cooperation and/or rivalry in the three main relationships in Japan's postwar political economy
DNS of turbulent channel flow with a flexible square cylinder
No full textFluid-Structure Interaction (FSI) problem is concerned with in various research fields such as mechanical, aerospace, civil and medical engineering. Their accurate prediction and control are desired. So far, in order to improve the performance of various applications, many kind of research, on the heat transfer enhancement due to vortex generator in heat exchangers, on the drag reduction through the setting of bluff body in pipe-line systems, and on the reduction of flow induced vibration, are conducted. In particular, since the wake of wall-mounted cylinder is a common flow regime in above-mentioned research, the detail of the flow has been aggressively investigated so far[1]. The present study, we pay attention to the flow control using flexible structures in the above mentioned flows. To investigate the potentiality of the control in advance, both high accurate and stable computational scheme is needed so that theactual phenomena including turbulence is well predicted. Therefore, in order to analyze the fluid-structure interaction, we propose aweak-coupling method[2] in which for flexible structures, the rigorous equations of motion are discretized with finite volume method (FVM[3]); for a flow computation, the finite difference method (FDM) is used and the flexible structures is reproduced via immersed boundary method[4]. In this present paper, we demonstrate on the result of flow structure around of rigid and elastic cylinder in turbulent channel flow
Developing countries'participation in the World Trade Organization
No full textIn the 1960s and 1970s developing countries viewed UNCTAD (United Nations Conference on Trade&Development) rather than the GATT (General Agreement on Tariffs&Trade) as the main institution through which to promote their interests in international trade. But beginning with the Uruguay Round in the mid-1980s, their attitude changed, many more of them became members of the GATT, and a significant number played an active role in negotiations. The author analyzes developing countries'representation and participation in the World Trade Organization (WTO) as of mid-1997 to determine how developing countries can effectively promote their interests and discharge their responsibilities under the rules and agreements of the new organization. He concludes that although many developing countries are actively participating in the new process, more than half of the developing countries that are members of the WTO participate little more than they did in the early 1980s and have not increased their staffing, despite the vastly greater complexity of issues and obligations. Institutional weaknesses at home are the main constraints to effective participation and representation of their interests at the WTO. To make their participation more effective, he recommends that the developing countries establish adequately staffed WTO missions based in Geneva; failing that, pooling their resources and representation in Geneva; and being sure to pay their dues, which are typically small. He also recommends that the international community place higher priority on programs of assistance in support of institutional development of poorer countries aimed at enhancing their capacity to participate in the international trading system and the WTO -- and that the WTO review its internal rules and procedures to ensure that inadvertently they do not make developing countries participation more difficult.Economic Theory&Research,Decentralization,Economic Conditions and Volatility,Country Strategy&Performance,Labor&Employment Law,Trade and Services,Poverty Assessment,Economic Theory&Research,World Trade Organization,Country Strategy&Performance

Prior to the present studyı eleven species have been described from around the world (see McCain and Steinberg 1970; Larsen 1997; Guerra-García 2002 ı 2003; Lim and Takeuchi 2012; Momtazi and Sari 2013).</p> <p> The present species was previously reported as <i>Metaprotella excentrica</i> Mayerı 1890 [<i>sense lato</i>] based on the specimens collected from Port Jacksonı New South Wales (see Mayer 1903 ı Stebbing 1910 ı McCain and Steinberg 1970. The type locality of <i>M. excentrica</i> was the Pamban Bridgeı Indiaı which is situated north of the Mannar between south-eastern India and northern Sri Lanka. <i>Metaprotella excentrica</i> [<i>sensu lato</i>] was also recorded from Ceylon (Sri Lanka) and Port Jacksonı New South Wales (see McCain and Steinberg 1970; Hutchings et al. 2013). Mayer (1890) first described this species based on the specimens from the type locality. Later Sivaprakasam (1977) described and figured a large male collected from Kilakkarai or Appa Island which is located on the Indian coast of the Gulf of Mannar. Guerra-García et al. (2010) also figured a mature male and female collected from Kasivari Island in the same Gulf of Mannar. All these figures for <i>M. excentrica</i> from India confirm the unique diagnosis for gnathopod 2ı which is the presence of three distal projections on the basis. Descriptions and/or figures of <i>M. excentrica</i> [<i>sensu lato</i>] from New South Wales have never been reported.</p> <p> <i>Metaprotella guileri</i> sp. nov. from New South Wales differs from <i>M. excentrica</i> [<i>sensu stricto</i>] from India by: (1) the head possessing a pair of small triangular projectionsı <i>M. excentrica</i> [<i>sensu stricto</i>] projections of head are smallı but sharp; (2) pereonites 2 and 3 having anteriorly forwarded mid-dorsal triangular projectionsı while those projections of <i>M. excentrica</i> [<i>sensu stricto</i>] are sharp; (3) pereonite 2 lacking a pair of posterior dorsal projection which <i>M. excentrica</i> possesses; and (4) the basis of gnathopod 2 with one to two distal projectionsı while <i>M. excentrica</i> [<i>sensu stricto</i>] has three distal projections. Thusı we establish the new speciesı <i>Metaprotella guileri</i>. Considering the biogeographical distributionı previous records of <i>M. excentrica</i> [<i>sensu lato</i>] recorded from Port Jacksonı New South Wales (see McCain and Steinberg 1970; Hutchings et al. 2013) could be <i>M. guileri</i> sp. nov.</p> <p> The specimens assigned as <i>Metaprotella guileri</i> sp. nov. were found in the old collection of the Australian Museum collected in Port Jackson and Jervis Bay and in materials collected in Port Jackson in 1996 and from Brush Island to Batemans Bay in the Hermon Slade Batemans Bay Expedition during 2003 to 2004. The male of materials collected in 1996 from Port Jackson (by ITı the senior author)ı where most of the old specimens were collectedı was selected as the holotypeı and the concurrently collected specimens were assigned as paratypes. While three mature females of the present species were found in the old collectionı these are not suitable for description and illustration due to being dried up or damaged. The largest male collected in the Hermon Slade Batemans Bay Expedition was also figured and described.</p> <p>The present species shows an unique ontogenetic development of gnathopod 2 in larger males. Of the specimens studiedı 4 males longer than 12.80 mm in body length possess the distinct proximal projection and two distal round projections on the basis of gnathopod 2.</p>Published as part of <i>Takeuchi, Ichiro & Lowry, James K., 2019, A taxonomic study on Orthoprotella and related genera (Crustacea: Amphipoda: Caprellidae) of New South Walesı Australia, pp. 1023-1059 in Journal of Natural History 53 (17)</i> on pages 1025-1032, DOI: 10.1080/00222933.2019.1589590, <a href="http://zenodo.org/record/3673283">http://zenodo.org/record/3673283</a>
Author Co-Citation Analysis (ACA): a powerful tool for representing implicit knowledge of scholar knowledge workers
No full textIn the last decade, knowledge has emerged as one of the most important and valuable organizational assets. Gradually this importance caused to emergence of new discipline entitled ―knowledge management‖. However one of the major challenges of knowledge management is conversion implicit or tacit knowledge to explicit knowledge. Thus Making knowledge visible so that it can be better accessed, discussed, valued or generally managed is a long-standing objective in knowledge management. Accordingly in this paper author co- citation analysis (ACA) will be proposed as an efficient technique of knowledge visualization in academia (Scholar knowledge workers)
ON THE γ-RAY MEASUREMENT AROUND THE YAMASAKI FAULT
No full textA γ-ray survey was carried out around the Yamasaki fault. The results were not so clearlyinterpreted as were made around the Ohbaku fault.An earthquake of magnitude about 4 occurred near the fault on Sept. 30, 1977. On 27 pointsamong the survey lines above mentioned, time variation of γ-ray intensity was examined by 4times of measurements, one of which was before the earthquake and the rest after it. The patternof the variation is similar to that of Chloride ion contents (Yoshioka (7)) in a spring near the fault.This suggests us that the continuous observation might have caught some precursory change ofthe earthquake occurrence. From the middle of Nov. continuous observation was started in theobservation tunnel of crustal movements at Yasutomi. It seems that high values of γ-ray intensityarise about 4 days after the peaks of the numbers of the microearthquakes and explosions near theregion.A γ-ray survey was carried out around the Yamasaki fault.
