Contractual governance and the choice of dispute-resolution mechanisms: Evidence on technology licensing

In fast-paced and knowledge-intensive environments, licensing partnerships can be powerful levers for market expansion. Research on the management of technology-oriented licenses has nonetheless pointed out the risks of corrosive disputes caused by conflicting interests or misunderstandings among licensing partners. The choice made ex ante on mechanisms for resolving potential disputes is of prime importance in the execution of licensing exchanges. Although the legal literature has widely emphasized the advantages of arbitration towards litigation, public ordering remains the “default” option in managers’ eyes. By adopting a transaction cost economics logic, our study explores the conditions under which licensing partners may prefer arbitration over public ordering during the contractual-design phase. In accordance with our theoretical arguments, findings show that the occurrence of arbitration provisions increases when the coordination orientation adopted by licensing partners is extensive. In situations where both monitoring and coordination orientations are simultaneously extensive, results reveal a greater propensity to prefer arbitration over public ordering. Our research therefore supports the view that corporate decision-makers tend to favor the conciliatory stance and compromising awards typically associated with arbitration, only when exchanges are expected to be highly coordinative. Their preference for arbitration over litigation is magnified when the coordination orientation develops alongside the monitoring orientation.     

PI3K阻断剂对大鼠运动骨骼肌Akt/mTOR信号的影响

目的:通过阻断PI3K信号,以深入探讨Akt/mTOR通路在抗阻运动中骨骼肌蛋白合成的作用。方法:8周龄雄性SD大鼠在适应性训练后分为4组:安静组(S)、阻断剂组(SL)、运动组(E)、运动+阻断剂组(EL),每组6只。运动方式为跑台运动(坡度为10%,跑速20 m/min,60 min),每天1次,共7 d。腹腔注射外源性LY294002(剂量为5.5 mg/kg)。用Western Blotting法检测腓肠肌MHC、Akt和mTOR蛋白表达、Akt(Ser473)和mTOR(Ser2448)磷酸化表达。结果:在一周后,LY294002明显抑制MHC,运动有促进的趋势,并减弱LY294002对MHC的抑制效应。LY294002显著抑制Akt和mTOR蛋白表达、Akt(Ser473)和mTOR(Ser2448)的磷酸化表达,而运动明显增强mTOR、Akt(Ser473)和mTOR(Ser2448)表达。结论:1)阻断PI3K信号可使运动骨骼肌Akt/mTOR通路受到明显抑制,而同时骨骼肌MHC明显降低,明显抑制肌肉蛋白合成。2)运动明显促进该通路的表达,并减弱PI3K阻断剂对该通路的抑制效应。3)PI3K阻...     

185nm紫外光/氧化协同降解水体中微量三氯甲烷的研究

文章研究了185nm紫外光/氧化协同降解水体中微量三氯甲烷的降解情况,考察了溶液浓度、光解时间、溶液pH值以及加入氧化剂等对降解三氯甲烷的影响,研究结果表明,CHCl3的脱氯基本是由185nm紫外光引起;其脱氯率几乎不受pH值的影响;在近中性条件下,5mg.L-1的三氯甲烷水溶液的CODMn去除率、脱氯率均与光解时间呈指数上升;光解5min后,CODMn去除率可达50%左右,脱氯率则小于30%;CHCl3的解离主要是185nm光子的作用,而与其它氧化性物质无关。     

运动训练对tau蛋白和Aβ的影响及与防治AD的关系研究

大量研究发现AD患者脑神经纤维tau蛋白的过度磷酸化形成NFTs,和Aβ在脑内的沉积形成老年斑,是导致AD发病的重要机制。在查阅了大量国内外有关tau蛋白和Aβ及运动对二者影响的文献的基础上,对导致tau蛋白异常过度磷酸化和Aβ产生的机制进行阐述,并就运动训练对tau蛋白过度磷酸化和Aβ的影响及防治AD的可能机制进行探讨。研究发现运动训练抑制了AD实验动物脑内tau蛋白的异常过度磷酸化和Aβ的沉积,在运动人体科学领域为体育运动防治AD的研究提供了可行性依据,也为AD的防治提供了除药物治疗外的新方法。

Should Trump Bother with an Education Agenda?

The principal opportunities awaiting the Trump administration in K–12 education are only loosely related to the candidate’s campaign comments about advancing school choice and reducing the federal Education Department. Recent passage of the Every Student Succeeds Act signals that Congress will be loath to re-open the major federal K-12 programs for amendment. Bright opportunities away in connection with the Perkins Act, special education and the Institute of Education Sciences (IES), as well as various domains--beginning with the Office for Civil Rights--that beg for strategic deregulation.     

南宋时期湖南人才波峰的成因及其思想特点

Field-based professional development of teachers engaged in distance education: experiences from the Arctic

We examine the experiences of five teachers who traveled with a team of educators, scientists, and explorers on circumpolar Arctic expeditions to deliver adventure learning (AL) programs to K–12 students at a distance. Results highlight the personal and professional impacts this opportunity had on teachers, including their empowering, fulfilling, and mentally exhausting experiences while assisting in delivering distance education to students worldwide. The article concludes with a discussion of issues to consider in the development of similar programs.
