Reflections on the Process Leading to Collaborative Research‐Based on Experiences of Joint Presentations at the Japanese Language Education Methods (JLEM) Conferences‐
Get PDF共同研究には、個人研究ではまかなうことができない①専門性、②多様な視点、③ネットワークの３つを補うことができるというメリットがあり、日本語教育の分野でも多くの共同発表が行われている。しかし、共同研究を行うためには、その研究を遂行するために適当な資質を有する共同研究者を見つけなければならない。本稿では、筆者がこれまでに日本語教育方法研究会（JLEM）で行ってきた20回の共同発表について、共同研究者とつながった経緯を、①同僚、②学会参加、③直接コンタクト、④プログラム、⑤学会運営、⑥紹介の6つのネットワークから概観しどのような形で共同発表に至ったかを述べるものである。A significant number of research projects take the form of collaborative efforts. Joint presentations at conferences and workshops can be considered one of the outcomes of collaborative research, and there are quite a few joint presentations in the field of Japanese language education. Collaborative research has the advantages of supplementing expertise, diverse perspectives, and networks that individual research cannot cover. However, to conduct collaborative research, it is necessary to find researchers with the appropriate qualities to carry out the research. Therefore, for researchers who are considering starting collaborative research, the first challenge is how to find such suitable collaborators. This paper outlines the connections with co-researchers in the 20 joint presentations the author has made at he Japanese Language Education Methods (JLEM), categorized into six networks: (1) colleagues, (2) conference participation, (3) direct contact, (4) programs, (5) conference management, and (6) introductions, and describes how these joint presentations were realized
Remark on the local well-posedness for NLS with the modulated dispersion
Get PDFWe consider the Cauchy problem of the nonlinear Schrödinger equation with the modulated dispersion and power type nonlinearities in any spatial dimensions. We adapt the Young integral theory developed by Chouk-Gubinelli [10] and multilinear estimates which are based on divisor counting, and show the local well-posedness. This generalizes the result by Chouk-Gubinelli [10] in terms of the dimension and the order of the nonlinearity

Structures and Electrochemistry of γ-Butyrolactone Solvates of Na Salts
Get PDFPhase behaviors, solvate structures, Na+ transport properties, electrochemical stability, and battery performance of binary Na salt and γ-butyrolactone (GBL) mixtures have been studied systematically. A concentrated [sodium bis(fluorosulfonyl)amide (NaFSA)]/[GBL] = 1/1 mixture remains in the liquid state at room temperature, and a single crystal of the same composition is obtained below room temperature. The Na metal/electrolyte interface is stabilized and continuous electrolyte decomposition is suppressed in molten [NaFSA]/[GBL] = 1/1, whereas GBL solvates of NaN(SO2CF3)2 (NaTFSA) and NaPF6 exhibit a continual increase in interfacial resistance at the Na metal electrode. Solvent-bridged (Na+−GBL−Na+) and anion-bridged (Na+−FSA−−Na+) structures are observed in the [NaFSA]/[GBL] = 1/1 single crystal. These ligand-bridged structures produce a remarkably high Na+ transference number of 0.84 due to dynamic ligand-exchange conduction of Na+ in the electrolyte. Although the ionic conductivity of [NaFSA]/[GBL] = 1/1 is less than that of typical Na+-based electrolytes, the rate capability of a Na0.44MnO2 electrode in molten [NaFSA]/[GBL] = 1/1 is slightly greater than that in 1 mol dm-3 NaPF6/propylene carbonate. This observation is attributed to a high Na+ transference number, which suppresses the development of a concentration gradient in Na+ batteries under anion-blocking conditions. These observations indicate that not only ionic conductivity but also Na+ transference number are essential electrolyte properties for achieving high rate capabilities in Na batteries
