The concept system around ‘quantity’ and ‘quantity value’ is fundamental for measurement science, but some very basic issues are still open on such concepts and their relations. This paper proposes a duality between quantities and quantity values, a proposal that simplifies their characterization and makes it consistent.

Quantity plays an important role in the analysis of a wide variety of phonological and morphological phenomena in many languages including the analysis of word stress, tone, compensatory lengthening, shortening processes, minimal word requirements, templatic restrictions and allomorphy selection. These phenomena frequently distinguish between syllables that are short (or light) from those that ...

量(Quantities)は、あらゆる場面で用いられ、我々が世界を理解するために重要な一部で ある。エンジンの馬力、サイズ、走行距離、自動車の価格など、様々な量について私たち は会話を行っている。 この論文では、それらの表現を生成する、認知的な量および法則の象徴的表現(symbolic representations)を提案する。言語学と心理学の分野から証拠を集めた結果、その表象は 2 種類に分けることが出来ると主張する。 ・Dimensional representations 「大きい」や「小さい」など、量の変化を意味するもの ・Structural representations 「沸点」や「貧困線」など、質の変化を意味するもの そこで、パイロット実験を行った結果、Dimensional な区別に関して、人々に共通する 特徴が存在することが示唆された。 また最後に、我々は計算モ...

In This Issue In This Issue Rabs make their way to mitochondria he large family of Rab GTPases has various functions, including the assembly of proteins required for endocytosis and membrane trafficking. Now, a new function for a Rab is emerging. On page 659, Alto et al. describe a Rab that affects mitochon-drial fission. This GTPase, Rab32, also has an unusual binding partner, the cAMP-depende...

Previous studies in the issue of inventory models with imperfect quality assumed the defectives could be sold in a batch by the end of the inspection process and the manufacturing systems were push systems. However, the above assumptions may not be true in the pull system in which buyer is powerful. Therefore, in this paper, we develop a new inventory model for items with imperfect quality and ...
