Uniform Plane Graphs

This paper presents two special classes of plane graphs characterized by the sequences M(v) and W(e). M(v) is the circular sequence consisting of the numbers of vertices on the meshes around vertex v ; and W(e) is the sequence consisting of the numbers of vertices on the meshes to the right and the left of edge e and also of the degrees of the head and the tail of e. A graph is called uniform with respect to M(v) or W(e) if its vertices all have the same M(v), or if its edges all have the same W(e), respectively. It is shown that if such a uniform plane graph exists for the given M(v) or W(e), the numbers of its vertices, edges and meshes are uniquely determined. Then, the conditions on M(v) or W(e) for the existence of a graph are investigated. Tables of plane graphs which are uniform with respect to M(v) or W(e) are presented. Besides regular polyhedrons, there are thirteen types of graphs which are uniform with respect to M(v), and only four graphs which are uniform with respect to W(e)

Endpoint Strichartz estimates and global solutions for the nonlinear Dirac equation

We prove endpoint Strichartz estimates for the Klein-Gordon and wave equations in mixed norms on the polar coordinates in three spatial dimensions. As an application, global wellposedness of the nonlinear Dirac equation is shown for small data in the energy class with some regularity assumption for the angular variable

Remarks on the Rellich inequality

We study the Rellich inequalities in the framework of equalities. We present equalities which imply the Rellich inequalities by dropping remainders. This provides a simple and direct understanding of the Rellich inequalities as well as the nonexistence of nontrivial extremisers. © 2016 Springer-Verlag Berlin HeidelbergEmbargo Period 12 month

Radioprotective Effect of Alk(en)yl Thiosulfates Derived from Allium Vegetables against DNA Damage Caused by X-Ray Irradiation in Cultured Cells: Antiradiation Potential of Onions and Garlic

To evaluate a radioprotective effect of sodium n-propyl thiosulfate (NPTS) and sodium 2-propenyl thiosulfate (2PTS) derived from onions and garlic, respectively, rat hepatoma H4IIE cells and mouse lymphoma L5178Y cells were preincubated with each of these compounds for 48 hours at 37°C before receiving 10 Gy of X-ray irradiation. Cell damage caused by the irradiation was quantified as comet tail moment, which represents the degree of DNA damage. X-ray-induced DNA damage was significantly decreased in both H4IIE and L5178Y cells by micromolar concentrations of NPTS and 2PTS compared with the control without the compounds. The protective effect was more potent with 2PTS than NPTS. Onions and garlic have antiradiation potential

アンチ「福祉国家」の租税=社会保障政策論 : ベーシック・インカム構想の新展開

1980年代以降、戦後「福祉国家」体制の動揺のなかでさまざまな再編、見直し論議が盛んに行われてきている。本稿では、ベーシック・インカム構想を取り上げ、その系譜の説明、類似の提案である負の所得税、参加所得、社会配当との比較検討などを行いつつ、アンチ「福祉国家」の租税=社会保障政策論として、自由主義者から社会主義者、エコロジストやフェミニストなど幅広い立場から多くの関心を集めている根拠を探っている。ベーシック・インカム構想が支持されているのは、人々を性別分業にもとづく核家族モデルから解き放ち、資力調査に伴うステイグマや「失業と貧困の罠」から解き放ち、不安定度が強まる労働賃金への依存から解き放ち、労働の人間化や自主的市民活動の広範な発展に寄与することが期待されているからである。ただ、労働と所得の切り離しの是非、公務労働の役割についてなど今後解明されるべき論点も残されている

ベーシック・インカム論と福祉社会の展望 : 所得と労働の関係性をめぐって

ベーシック・インカムの持つ所得と労働を切り離す側面に焦点をあて、資本主義社会において所得保障と労働(賃労働)が結びついていることの意味をA.ゴルツの所論によりながら検討し、ベーシック・インカム保障が大幅な労働時間短縮とワークシェアリング、就労支援政策や自発的な社会貢献活動の活性化政策と結合することが重要であるが、就労を所得保障の条件とするようなワークフェア政策とは一線を画すべきであることを論じた。次いで、消費論からみた所得と労働の関係性も検討し、労働時間の短縮によってゆとりある生活を行うことが、加速化する消費主義の熱を冷まし「浪費と働きすぎの悪循環」(ショア)というもう一つの所得と労働の関係を人間化することにつながることを論じた
