"Measuring the Cost of Imperfect Information in the Tokyo Housing Market"

The cost of imperfect information is estimated in the real estate market of resale condominiums in central Tokyo by using a new, comprehensive data set of resale condominium transactions. The results suggest a substantial cost. Specifically, if information were perfectly available and marketing time is null, sellers would get benefits of 10.58% based on average interest rate, 31.28% on gross rent and 22.59% on net rent, against imputed rent of their property. Buyers spend 1,042,000 Yen on search activities for one transaction, which would be saved if information were prefect. This cost amounts to be equivalent to 13.2% of buyers' average annual income.

Complete set of electromagnetic corrections to the nucleon mass in the Nambu-Jona-Lasinio model

We show how to derive the complete set of electromagnetic corrections to the Nambu-Jona-Lasinio (NJL) model of the nucleon. Our results enable an accurate estimate of the electromagnetic contribution to the neutron-proton mass difference within this model. At the same time, our procedure demonstrates the way to calculate the complete set of meson corrections to the NJL model that maintains chiral symmetry.Comment: Contribution to Proceedings, KEK-Tanashi International Symposium on Physics of Hadrons and Nuclei, 14-17 December 1998, Tokyo, Japan, to be published in Nuclear Physics A. 5 pages, revtex, epsf, 2 postscript figures.

On the Kauffman-Harary conjecture for Alexander quandle colorings

The Kauffman-Harary conjecture is a conjecture for Fox’s colorings of alternating knots with prime determinants. We consider a conjecture for Alexander quandle colorings by referring to the Kauffman-Harary conjecture. We prove that this new conjecture is true for twist knots.The Kauffman-Harary conjecture is a conjecture for Fox’s colorings of alternating knots with prime determinants.

The Importance of Cohesion in Academic Writing

This paper analyzes academic essays written by Japanese university students. One of their weak points lies on a lack of coherence in their writings. In order to investigate the characteristics of their writings in English, I conducted a micro-level analysis based on a student\u27s essay and a macro-level analysis by using learner corpus consisting of 21 students\u27 essays. The findings show that Japanese students have difficulty with using cohesive devices such as reference and conjunction

Student-Initiated Student-Repair in Classroom

This paper analyzes a classroom data of English class on short-term study abroad programme, and focuses on how Japanese students repair their mistakes. Although teachers usually play an important role in correcting students\u27 mistakes in a classroom, students occasionally do amend their utterances. The data shows how the student cooperates with other student in order to repair own mistake by using Japanese Aizuchi (backchannelling). Through the analysis of repairs using Aizuchi in class, it helps teachers understand why communication breakdown occurs and prompts students to achieve communicative competence in their target language

Towards the successful implementation of the updated OECD Guidelines for Multinational Enterprises

Manfred Schekulin and John Evans have each written Perspectives discussing the 2011 update to the OECD‘s Guidelines for Multinational Enterprises. The Guidelines have several potential impacts, including impacts on MNEs' interactions with their supply chains. Further, to be successful, it is important that the Guidelines are incorporated into MNEs' codes of conduct. It is also essential for emerging markets to adhere to the Guidelines
