An Extensive Analysis on the Japanese Markets via S. Taylor's Model

Abstract: Applying S. Taylor's approach (1986), we make an extensive analysis on the Japanese stock market, foreign exchange market and the Japanese Government Bond Futures market. The purpose of this paper is to empirically reveal the structure of the Japanese markets via Taylor's model rather than to propose a new model. For this reason, we include a variety of analyzed data particularly for the Japanese stock market and the foreign exchange market because the results can be used in a different manner. The paper consists of three parts. But each part can be read separately.

Inclusive wealth, total factor productivity, and sustainability: an empirical analysis

Abstract: Sustainability can be assessed by non-declining inclusive wealth, which refers to man-made capital, human capital, natural capital, and all other types of capital that are sources of human well-being. As the previous studies—including Arrow et al. (J Econ Perspect 18(3):147–172, 2004) and the Inclusive Wealth Report (2012 and 2014)—suggest, total factor productivity (TFP) is one determinant of inclusive wealth, because it is related to the resource allocation mechanism. TFP is one important component of sustainability. When considering the contribution of TFP toward inclusive wealth, attention needs to be paid to the improvement in the usage of human and natural capital as well as the traditional man-made capital. However, in the previous studies, only man-made capital and labor force have been considered. This study extends current measures of sustainability by capturing the efficient utilization of natural resources, giving us inclusive wealth-based TFP. Therefore, in contrast to conventional TFP measures, we consider both human and natural capital in addition to man-made capital. We examine 43 countries and find that a new indicator which asserts countries previously considered sustainable by earlier studies such as Arrow et al. (J Econ Perspect 18(3):147–172, 2004) as no longer sustainable.

Genetic Assessment of a Hybrid Population between Japanese and Taiwan Macaques in Wakayama Prefecture

Abstract: We conducted genetic assessment on a postulated hybrid population between Taiwan macaques (Macaca cyclopis) and Japanese macaques (M. fuscata) inhabiting Ooike and the surrounding area in Wakayama prefecture in 1999. The population originated with the introduction of Taiwan macaques in the area in 1955. Two social groups, of approximately 200 animals in total were observed, indicating an annual growth rate of 3.0-6.7% following introduction. From our analysis of diagnostic genetic markers (three kinds of blood proteins and mitochondrial DNA D-loop sequence), the degree of interspecific hybridization could be quantified and the breeding structure assessed. Six of the nine animals examined were identified as hybrids born in the study area after more than one generation of mixture. Two of the remaining animals showed a Taiwanese macaque-like genetic profile and the last was Japanese macaque-like. Approximately one forth of the Taiwanese gene pool has already been replaced with Japanese macaque genes over the last 45 years. The migration rate from out groups of native Japanese macaques was estimated to be 0.6% per year and 5.9% per generation. These results strongly suggest that the two macaque species are intermixing without reproductive constraint in the area. This man made hybrid zone risks disturbing of the gene pools and biological features of native Japanese macaques in surrounding areas. The impact of expansion of exotic genes into Japanese macaque habitats is discussed based on the obtained estimates of demographic and genetic parameters.

Hybrid Modeling Approach for Supply-Chain Simulation

Abstract: This paper proposes a novel simulation-modeling framework that combines discrete-event simulations with system-dynamics simulations The former represents both operational processes inside of a supply-chain, and the later represents management environment outside of a supply-chain Further, the paper also discusses modeling capabilities of the proposed framework for supply-chain systems in real world by using several example simulation models
