Decadal-scale reduction in net primary production in the western subarctic North Pacific : impact of lateral transport of dissolved iron from the Sea of Okhotsk
No full textThe subarctic North Pacific (SNP) is a high-nutrient low-chlorophyll region in which decoupling of dissolved iron (dFe) and macronutrient is an essential control of primary production. In this study, we evaluate the influence of decadal-scale climate change on the net primary production (NPP) in the SNP by performing a hindcast experiment for 1979–2016 using an ice–ocean coupled model with a simple biogeochemical model with iron cycle. Simulation results show a significant NPP decrease in the subtropical–subarctic gyre boundary (SGB) region since the 1990s; the trend is −48 mgC m−2 d−1/37 years with a magnitude that is 14.3% of the climatological mean NPP. The NPP decrease in the SGB is prominent during the spring, indicating weakening of the spring bloom. Diagnostic analysis of simulation data reveals that the NPP decrease in the SGB can be explained by the decrease in both dFe and light availability. Sensitivity experiments indicate that wind-driven circulation change mainly explains both the reduction in dFe and the light availability through the northward expansion of oligotrophic subtropical water, but the thermohaline change in the Sea of Okhotsk also has a non-negligible effect on the dFe reduction. Results from our numerical model simulations suggest the importance of lateral and vertical advection of dFe on the decadal-scale changes of NPP in the SNP
An Exordium of Theories of Law’s Nature on the Social Security Law : What the Social Security Law Studies can learn from the Philosophy of Law
No full textThis paper discusses what the social security law studies can learn from key concepts in the philosophy of law. The theory of the three types of law corresponds to the three dimensions of social security law—rights protection, policy implementation and support for autonomy—indicating the importance of these aspects, while the theory of dialogical rationality shows that agreement, deliberation and procedure are crucial at every stage of the legislation, interpretation and operation of social security law. In terms of rights theory, social security law aligns with the interest theory of rights for the right to life, while the freedom-based theory and the participatory-contributory support theory of social security law are compatible with the will theory of rights. Meanwhile, Hohfeld’s classification of rights is useful for analysing the complex rights within social security. Regarding various theories on the duty to obey the law, any of consent theory, obligation theory, benefit theory or relational duty theory can explain the rationale for mutual aid by social security law, but relational duty theory holds a dominant position. Ronald Dworkin's theory of legal integrity, which views law as a mechanism for 'equal respect and concern', is well-suited for social security law. Finally, the theory of relationality is compatible with the participatory-contributory support theory in social security law
［招待講演］DNSを活用した研究で着目した幾つかのリソースレコードの紹介
No full textDomain Name System (DNS) による名前解決はインターネットにおいて重要な役割を果たしており、サービスプロバイダーやインターネットユーザに欠かせないサービスの一つである。そのため、DNSによる名前解決ログは効率的なインターネットサービスの提供、不正通信の検知と遮断、インターネットユーザのプライバシー保護などにおいて重要な参考情報となっている。本稿では、著者らがDNSを活用した研究で着目してきた幾つかのリソースレコードを取り上げ、それらを活用した応用研究を紹介する。Domain Name System (DNS) plays an important role in the Internet in terms of domain name resolution. Almost of all Internet service providers and Internet users utilize DNS-based domain name resolutionservice. DNS provides many types of resource record for domain name resolution service. In this paper, we pick up several types of DNS resource record focused in our researches and introduce some of them practically utilizing DNS
A numerical solution method for the fractional moment problem within engineering
No full textIn the field of engineering, the fractional moments of random variables play a crucial role and are widely utilized. They are applied in various areas such as structural reliability assessment and analysis, studying the response characteristics of random vibration systems, and optimizing signal processing and control systems. This study focuses on calculating the fractional moments of positive random variables encountered in engineering. By integrating Laplace transforms with fractional derivatives, both analytical and practical numerical solutions are derived. Furthermore, specific practical application methods are provided. This approach allows for the stable and highly accurate calculation of fractional moments based on the integer moments of random variables. Data experiments included in this study demonstrate the effectiveness of this method in solving fractional moment calculations in engineering. Compared to traditional methods, the proposed method offers significant advantages in stability and accuracy, which can further advance research in the engineering field that employs fractional moments
Flowers of the Rear Garden : Representation of Male Homosexuality in Pornography of the Late Ming and Early Qing Dynasties
No full text明清時期のポルノグラフィーにおいて，「後庭花」は男色の隠語として多用されていた。しかし，具体的に「肛門」または「肛門交」なる行為を指すこの語彙は，必ずしも男性に限って用いられるものではない。小論は明末清初に刊行されたポルノグラフィーの作品群を取り上げ，「後庭花」を手がかりに，肛門交に関する描写に注目し，作品における異なるアプローチを分析し，男色の扱われ方を考察する。後半では，清代初期の刊行と想定される二つの小説『桃花影』と『春灯鬧』を取り上げ，そのやや特殊な男色の描き方を緻密に読み解き，男色描写がいかにジェンダーの越境と抑圧につながるのかについて考察する
Interpretation Issues of the Antecedent in the Chinese “DOU” : A Contrast with the Japanese “X TOMO”
No full text先行研究によれば，“都”は必ず先行詞を最大値と解釈させるとは限らず，先行詞を部分集合の集合と解釈させる機能を持つ。これは“都”構文に自由変項（Cov）があるためであり，“都”が何を全称量化するのかは文脈によって異なると説明されている。しかし，文脈が明確な場合，その部分集合を構成する要素，つまり，先行詞の値を決定するメカニズムについては言及されていない。また，日本語では“都”と同じく先行詞を部分集合の集合と解釈させる機能を持つ要素は何なのかについて検討した先行研究も管見の限りない。筆者は中国語の“都”と日本語の「Xとも」が全称量化詞であり，それらの姉妹位置に空範疇のEVERYが存在すると考える。そして，例外が言及された“都”構文と「Xとも」構文を，例外が言及されていない“都”構文と「Xとも」構文と比較し，Reinhart（1997）の提唱した選択関数を用いて，“都”と「Xとも」の先行詞の値は選択関数で決まると主張する
