Transition of Multicultural Symbiotic Policies in Japan: Case Studies Analysis of Tokyo, Toyohashi and Minamiuonuma City

How to attract foreign human resources and settle in has been one of the main issues of Japan where is facing depopulation and required to lead local regeneration with diversity. This paper introduces the transition of multicultural symbiotic policies in Japan and case studies at city level based on the collected data by in-depth interview in 2015. Data was collected in three advanced case studies, Tokyo, Toyohashi, and Minamiuonuma city. Through the overview of transition of policies and case study analysis, this paper attempts to find the fundamental and potential gaps between policies and actual condition at national and city levels in Japan

Thermal dependency of shell growth, microstructure, and stable isotopes in laboratory‐reared Scapharca broughtonii (Mollusca: Bivalvia)

We experimentally examined the growth, microstructure, and chemistry of shells of the bloody clam, Scapharca broughtonii (Mollusca: Bivalvia), reared at five temperatures (13, 17, 21, 25, and 29°C) with a constant pCO2 condition (∼450 μatm). In this species, the exterior side of the shell is characterized by a composite prismatic structure; on the interior side, it has a crossed lamellar structure on the interior surface. We previously found a negative correlation between temperature and the relative thickness of the composite prismatic structure in field‐collected specimens. In the reared specimens, the relationship curve between temperature and the growth increment of the composite prismatic structure was humped shaped, with a maximum at 17°C, which was compatible with the results obtained in the field‐collected specimens. In contrast, the thickness of the crossed lamellar structure was constant over the temperature range tested. These results suggest that the composite prismatic structure principally accounts for the thermal dependency of shell growth, and this inference was supported by the finding that shell growth rates were significantly correlated with the thickness of the composite prismatic structure. We also found a negative relationship between the rearing temperature and δ18O of the shell margin, in close quantitative agreement with previous reports. The findings presented here will contribute to the improved age determination of fossil and recent clams based on seasonal microstructural records
