捕鯨論争における英語支配：国際捕鯨委員会における言説の分析

The International Whaling Commission (IWC), the inter-governmental bory for manafement of whaling and resources, shifted from the science-based policies for the industry to the ethic-mased policies for animal protection., which led to the moratorium for mst whaling operations undes its jurisdiction. This paper critiaclly analyzes the discourse at the IWC for the most critical decades (1967-1987), and shows how scientific categories and arguments for resource management weere replaced by essentially ethical (thus culturally bound) categories and arguments.It also points out that English, the only official and working language of the IWC, plated a significant role in manipulation of the discourse

Rigged Hilbert Space Approach for Non-Hermite Systems with Positive Definite Metric

We investigate Dirac's bra-ket formalism based on a rigged Hilbert space for a non-Hermite quantum system with a positive-definite metric. First, the rigged Hilbert space, characterized by positive-definite metric, is established. With the aid of the nuclear spectral theorem for the obtained rigged Hilbert space, spectral expansions are shown for the bra-kets by the generalized eigenvectors of a quasi-Hermite operator. The spectral expansions are utilized to endow the complete bi-orthogonal system and the transformation theory between the Hermite and non-Hermite systems. As an example of application, we show a specific description of our rigged Hilbert space treatment for some parity-time symmetrical quantum systems.Comment: 10 page
