Market entry strategy in the presence of market spillovers and efficiency differentiation

Firms form various alliances or use brand extensions to enter new markets in order to improve their operational efficiency and create a positive spillover. However, they do not always know the implications of these strategies for market entry and multimarket competition because the sale of products in one market can have negative spillover effects on product sales in other markets. We present an analytical framework to examine whether and how (i.e., by choosing alliance entry or independent entry) competing firms should enter a market in a situation where market spillovers occur when a firm enters a spillover-producing market to sell products that may increase or decrease the consumers' willingness to pay for products in the primary market. Our analysis shows that the operational efficiency (or quality differentiation ability) of firms in a spillover-producing market varies, and hence, the impact of market spillovers differs for firms. We identify the key factors, such as bargaining power, brand value difference in the primary market, and the extent of efficiencies and spillovers, that determine the firms benefitting from the different entry strategies. Specifically, we show that firms would be more willing to choose an alliance strategy to enter a spillover-producing market if the negative spillover is small and alliance efficiency is high. In contrast, if an alliance entry is not favored, the firms' relative operational efficiency is crucial for them to decide whether to enter the market independently under moderate spillover conditions. Finally, we show the implications of market entry strategies for managers.     

新型教学模式下教学路径探讨——基于本科教育“四个回归”

实现本科教育的“四个回归”,是新时代背景下高等本科教育教学改革应该完成的目标。要围绕学生的主体地位来建构新型教学模式下教学路径中的学生角色。学生刻苦学习是学生主体学习地位的基础,实行一定比例的淘汰制是学生刻苦学习的重要保证,助力实现“回归常识”。在教师主导课程学习的过程中,要以学生究竟能学到什么和事实上学到什么作为衡量教学效果的标准,助力实现“回归本分”。课程全过程评价方式是动态全方面的评价方式,改变了目的性极强的单一期末考试评价机制,打破了期末考试一考定成绩的传统做法,助力实现“回归初心”和“回归梦想”。     

站在发展的新起点上继续解放思想

站在发展的新起点上继续解放思想,关键在于冲破妨碍科学发展的种种束缚,始终与时代同步,主动与世界接轨,坚持与强者为伍,自觉与科学结伴,保持与兵心相通;站在发展的新起点上继续解放思想,应始终坚持从社会主义初级阶段的国情与军情出发,始终坚持以马克思主义中国化的重大成果为指导,始终坚持把又好又快作为解放思想的根本着眼点和落脚点。

Investigation of the shock compression behaviors of Al/PTFE composites with experimental and a 3D mesoscale-model

The responses of AI/PTFE reactive materials (RMs) under shock compression were investigated by a single-stage gas gun.A 3D mesoscale-model was established based on micro-computed tomography(micro-CT) slice images and confirmed with experimental results.In the high-pressure stage,the com-posites reacted partially,whereas there were no deviations between the partially reacted Hugoniot and the inert simulation results.The simulation reveals that the Teflon matrix melting on the high shock pressure.Melts and decomposition of the PTFE accelerated the diffusion of the atoms.Thus,the reactions of the Al/PrFE composites are more like a combustion rather than a detonation.     

坚持以科学发展观为指导加强军队思想政治建设

坚持以科学发展观为指导加强军队思想政治建设,必须坚持把思想政治建设摆在各项建设的首位。把思想政治建设摆在各项建设的首位,体现了以人为本的要求,是各项工作全面协调发展的客观要求,是保证部队全面建设持续健康发展的客观要求。同时,还必须准确把握思想政治建设的职能和任务,提高思想政治建设标准。各级领导都要重视思想政治教育,各项教育都要以理服人,各类干部都要善于做思想工作,各项工作都要做出思想性,各种规则规定的目标指向都要与社会主义核心价值取向相一致。     

分层土中桩筏基础荷载分担

结合一个桩筏联合基础的设计过程,探讨了在复杂地基土上基础设计中的受力分析及变形协调计算过程.介绍了在满足复合地基承载力和变形要求前提下合理布置桩筏联合基础的做法及其设计思路.布置桩筏联合基础时使桩筏分别落在不同土层上,以充分利用不同深度地基土的承载力;另外针对桩下为非淤泥系硬土层,应最大限度利用桩身强度和天然地基承载力.该做法可以取得很好的经济效益,可供工程设计人员参考.
