Sphingosine-1-phosphate (S1P) has been implicated in tumor angiogenesis by acting through the Gi-coupled chemotactic receptor S1P1. Here, we report that the distinct receptor S1P2 is responsible for mediating the G12/13/Rho-dependent inhibitory effects of S1P on Akt, Rac, and cell migration, thereby negatively regulating tumor angiogenesis and tumor growth. By using S1P2LacZ/+ mice, we found that S1P2 was expressed in both tumor and normal blood vessels in many organs, in both endothelial cells (EC) and vascular smooth muscle cells, as well as in tumor-associated, CD11b-positive bone marrow-derived cells (BMDC). Lewis lung carcinoma or B16 melanoma cells implanted in S1P2-deficient (S1P2-/-) mice displayed accelerated tumor growth and angiogenesis with enhanced association of vascular smooth muscle cells and pericytes. S1P2-/- ECs exhibited enhanced Rac activity, Akt phosphorylation, cell migration, proliferation, and tube formation in vitro. Coinjection of S1P2-/- ECs and tumor cells into wild-type mice also produced a relative enhancement of tumor growth and angiogenesis in vivo. S1P2-/- mice were also more efficient at recruiting CD11b-positive BMDCs into tumors compared with wild-type siblings. Bone marrow chimera experiments revealed that S1P2 acted in BMDCs to promote tumor growth and angiogenesis. Our results indicate that, in contrast to endothelial S1P1, which stimulates tumor angiogenesis, S1P 2 on ECs and BMDCs mediates a potent inhibition of tumor angiogenesis, suggesting a novel therapeutic tactic for anticancer treatment. ©2010 AACR.

社会科学に新しいパラダイムを提示した研究として名高いホーソン研究は,幾度もなく厳しい批判にさらされてきている。興味深い点は,これらの諸批判が,大学の入門教科書では,ほとんど取り上げられていないという点である。本研究は,ホーソン研究の諸批判に焦点を絞る。そして,その意義や貢献だけではなく,諸批判も同時に教えることが,学生たちのマネジメントに対する多様なアプローチにつながる可能性を明らかにする。Hawthorn Studies are very famous for having suggested a new paradigm in social sciences. However, there is another story; many scholars have criticized that the studies are full of methodological problems and lack scientific evidences supporting the popular interpretation of the results. It is very surprising that the criticism has rarely been mentioned in introductory textbooks of I-O Psychology and Organizational Behavior. This study focuses on the criticism for Hawthorn Studies, especially in terms of methodological problems and the interpretation of research results. I argue that teaching the criticism help students learn much more balanced perspectives to management.

Based on the Liye 里耶 Qin strips, there existed three districts (鄕) in Qianling 遷陵, which are thought to have been located along the You 酉 river. The number of households registered in this prefecture was a mere 150-200, and three groups constituted the population : immigrants who came during the Qin occupation, colonists before unification, and natives. Among the native populace, some groups may have submitted to the Qin authority while maintaining their old social order. They were likely to have been divided from other commoners, and separately registered as "new citizens" (新黔首). Moreover, it seems reasonable to suppose that there were groups of men who were not under the administrative control of the Qin. Although the registered households were very few, the prescribed number of officials in Qianling was over 100. In addition, about 1, 000 convicts and over 600 soldiers were stationed there. This fact indicates the existence of members of the populace who had not submitted to the Qin in this area. Qianling prefecture played a role as a bulwark against hostile peoples who would invade the Xiang 湘 river system through the You river. In this sense, Qianling was a prefecture on the frontier. There were several types of soldiers stationed in Qianling : including gengshu 更戍 (short-term soldiers conscripted by rotation), rongshu 冗戍 (long-term military volunteers), and fashu 罰戍 (criminals forced into military service). Certain tendencies concerning their hometowns and times of conscription can be seen for each type of soldier. For example, soldiers tended to be conscripted from Nan 南 commandery just after the unification, and fashu from "the region within the passes" (關中), or the relatively old territory in "the east of the passes" (關東), were also dispatched to Qianling. Later, around the 33rd year of the reign of the First Emperor, the year when the expedition to Lingnan 嶺南 started, gengshu from the region occupied just before the unification appeared in this prefecture. It was the Xianwei 縣尉, or the Prefectural Commandant, who took charge of these soldiers. As an official in charge of prefectural military administration, the Xianwei was somewhat independent from the civil administrative organization led by the Xianling 縣令, or Prefectural Director. It was the Xiaozhang 校長, or the Guard Commander, who led the troops as a subordinate of the Xianwei. Soldiers were organized into units of five or ten, and these units were commanded by a Dunzhang 敦長. In addition to this organization of the prefectural army, commanders who belonged directly to the commandery were stationed in the Qianling prefecture with their troops. It is thought that they were likely to have been outside the control of the Xianwei, so we can assume that the total scale of the garrisons in Qianling was larger than that of the prefectural army, which was composed of about 600 soldiers.

Yongwanggung (Ryuogu/Ryuokyu),a renowned shamanism mecca for the first generation of Korean residents in Japan(especially,female residents from Jeju Island)disappeared,following an eviction order from the local government.It was only a few years before its dismantling that serious research started on its facilities and prayers.Previous research,however,left several important questions unanswered.This paper,mainly based on interviews of prayers and their family members,investigates and rediscovers the meaning of the `prayer community',and argues that shamanistic rituals carried out at several places,including Ryuogu,prayers home,Buddhist temples called Chosendera (Korean temples in Japan),are part of the first generation female residents' prayer activities,which are in turn part of the traditional culture of the first generation Korean residents.It also argues that though the rituals originated from Jeju island,they are adapted and transformed for Korean residents in Japan.From the deviation,we are able to read the life strategies of the first generation female residents.However,the prayer community,composed of mostly the first generation with some exceptional second generation residents,is destined to be isolated and separated from other generations and communities. The Shamanistic rituals of Korean residents in Japan are the scenes where oppositions or conflicts causedby the generation gaps,and educational and cultural background differences are revealed.

ハードウェア的なMIDI音源(M音源)と、ソフトウェア的なGMサウンドドライバについて、MIDI信号入力から発音開始までの遅延時間のばらつきを計測した実験について、多種のMIDI音源の計測結果を詳細に報告する。この結果から推定される音源処理アルゴリズム(IDI入力から発音までの信号処理)に関する考察を行い、音楽心理学的実験に使用できる場合と、実験の意味を失うために使用できない場合とを整理する。また、音源アルゴリズムを現実的に改良するための提案を行う。The purpose of this paper is to examine the delay of hardware/software sound generators from MIDI input and its deviations, and to consider its causes and its serious matter for research of psychoacoustics and its solution.
