次元形容詞「高い」の意味体系に関する日中対照研究《論文》

日本語の「高い」と中国語の“高（gāo）”には，空間的用法と非空間的用法が見られる。そのうち，「高い」と“高”の非空間的用法に違いが見られるが，その背後には，意味の捉え方に違いが存在する可能性があると考えられる。しかし，今までの「高い」と“高”に関する研究では，言語的な知識の記述と分析が中心になっており，言語主体の認知能力や運用能力との関連で，意味体系の実態を明らかにした研究は少ない。 そこで，本研究では，國廣（1971），西尾（1972），籾山（2001）の研究を踏まえ，「高い」と“高”の空間的用法と非空間的用法に見られる複数の意味を記述し，複数の意味の間の関係をネットワークとして示した上で，「高い」と“高”の意味拡張の認知プロセス，意味体系のありかたを検討し，その相違点を探ってみた。 「高い」と“高”の意味体系の対照を通して，次のような結論が得られた。(1)「高い」と“高”は，プロトタイプ的意味，意味拡張に見られる認知プロセスが大きく類似している。(2)「高い」と“高”の空間認知において，五感を介する経験が経験的基盤となる点で共通している。しかし，五感のうち，嗅覚経験を介する対象の捉え方に違いが見られる。(3)「高い」と“高”の意味体系において，空間的用法は起点領域という役割をし，非空間的用法はイメージが写像される目標領域の役割を果たしている。したがって，「高い」と“高”の非空間的用法には違い見られるが，意味拡張の仕方と意味の捉え方は類似していると考えられる。 Dimensional adjectives of height, “takai” in Japanese and “gāo” in Chinese, have spatial and non-spatial uses. It is noteworthy that their non-spatial uses are slightly different from each other. This seems to be due to the fact that the cognitive modes how their meanings are cognized are different. The semantic studies on these words hitherto made mainly center around the description and analysis of their linguistic meanings. There are not so many works, on the cognitive and performance ability of their user that elucidated the cognitive system for their semantics. Based on the works by Kunihiro (1971), Nishio (1972) and Momiyama (2001), I reconsidered the multiple meanings of “takai” and “gāo”, describing the relations among them in terms of a semantic network. I explored the cognitive processes in which the meanings of both words are extended and their whole semantic systems in which they develop, and identified some difference between them. Comparing these two words, we have concluded the following three points. (1) Their prototypical meanings and their cognitive processes for meaning extension as well are highly similar. (2) The modes in which their users cognize space are similar to each other in how the objects evaluated by them are experienced in terms of all the five senses but the sense of smell. (3) Their spatial uses both belong to the region from which their users view the relevant object, and their non-spatial uses both belong to the region on which the image of the cognized object is projected. Thus, both words are supposed to be similar in extension and cognition of their meanings.textapplication/pdfdepartmental bulletin pape

Search for \bar{B}^0 →Λ_c^+\bar{Λ}_c^- decay at Belle

We search for the doubly charmed baryonic decay \bar{B}^0 →Λ_c^+\bar{Λ}_c^-, in a data sample of 520×106 B\bar{B} events accumulated at the Υ(4S) resonance with the Belle detector at the KEKB asymmetric-energy e^+e^- collider. We find no significant signal and set an upper limit of B(\bar{B}^0 →Λ_c^+\bar{Λ}_c^-)< 6.2×10^{-5} at 90% confidence level. The result is significantly below a naive extrapolation from B(B^-→　Ξ\begin0\c\end\bar{Λ}_c^-) assuming a simple Cabibbo-suppression factor of |V_cd/V_cs|^2. The small branching fraction may be attributed to a suppression due to the large momentum of the baryonic decay products, which has been observed in other charmed baryonic two-body B decays.journal articl

First comprehensive inter-comparison of aerosol electrometers for particle sizes up to 200 nm and concentration range 1000 cm −3

The concentration of nanometre-sized particles is frequently measured in terms of particle number concentration using well-established measuring instruments, e.g. condensation particle counters. Traceability for these measurements can be achieved by means of calibrations using an aerosol electrometer (AE) as a reference. A number of national metrology institutes (NMIs) and expert laboratories provide such calibrations, but the metrological basis is at present not well established because the equivalence between the unit realizations has not been investigated by means of an inter-laboratory comparison. This paper presents the results of the first comprehensive comparison of AEs involving NMIs and expert laboratories worldwide. The comparison covered the particle size and charge concentrations ranges 20 nm to 200 nm and 0.16 × 10-15 C cm-3 to 2.72 × 10-15 C cm-3 (equivalent to 1000 cm-3 to 17000 cm-3 singly charged particles), respectively. The obtained results agreed to within about ±3%, which was within stated uncertainties, with only a few exceptions, such as at low concentrations. Additional measurements with sub-20 nm particles show that comparisons in this size range are more challenging and require special considerations, though agreement to within about ±5% was still found with 6 nm particles. This comparison is the first and vital step towards internationally recognized SI traceability in particle number concentration measurements
