Z_P群中N维广义正方体上的哈密顿回路

设Z_P={1,2,…,P-1,0},在模P的加法运算下,Z_P是一个群。Z_P上定义n维广义正方体,其顶点集为{(x_1,x_2,…,x_n):x_i∈Z_P.i=1,2,…,n},两个顶点x和y之间有一条棱,当且仅当sum from i=1 to n丨x_i-y_i丨=1 mod(P)。在这个定义下,本文证明了对任意P≥2和n≥2,Z_P中n维广义正方体上存在一个经过所有顶点的哈密顿回路。文中给出了一些例子作为应用。     

理路与实践：马克思主义大众化传播的高校担当

传播马克思主义是高校光荣历史传统和重要时代使命。高校具有马克思主义社区传播的独特时空、主体及资源优势,基层社区是高校传播和践行马克思主义,师生深入“社会大课堂”和“将论文写在祖国大地”的重要场域。本案例HN大学青年理论社团精准对接基层社区开展马克思主义传播实践的创新经验是校地同构的街道“一体两翼多元四联”传播共同体,共辟全域协同传播阵地,共享立体多维传播资源。案例的启示是要提升高校对基层社区的马克思主义传播力和影响力,树立传播责任意识是前提,建设传播服务团队是根本,完善传播激励机制是关键,提供精准长效传播服务是方向。     

品牌延伸:资产价值转移与理论模型创建

本文通过对品牌延伸(Brand Extension)的研究综述和实证研究,提出决定品牌延伸的三大因子,并在此基础上构成品牌资产价值(Brand Asset Value),进而研究其在品牌延伸过程中的价值转移,从而构成了评估品牌延伸成败的标准,最终将各种因子和评估标准进行整合,提出了品牌延伸的理论模型。     

农业社会学:经典命题及其延续

作为一门新兴学科,农业社会学近年来在中国呈现出良好的发展势头。一门学科的发展,需要通过不断的知识积累和经验研究进行一砖一瓦的建设,其中理论建设尤其重要。同其他社会科学一样,经典文本在农业社会学的理论建设中具有核心位置。 本专题选取了三个(对)农业社会学中的经典命题:农业的生产时间与劳动时间、农业技术变迁中的占取主义与替代主义,以及技术采用中的“农业跑步机理论冶。按照时代背景、原典阐释、学术延续以及启发意义的思路撰写,尝试为农业社会学的入门者提供一种理论梳理的路径。     

Building up Resilience in a Pharmaceutical Supply Chain through Inventory,Dual Sourcing and Agility Capacity

This paper is inspired by a risk management problem faced by a leading pharmaceutical company. Key operational risk mitigation measures include Risk Mitigation Inventory (RMI), Dual Sourcing and Agility Capacity. We study the relationship between these three measures by modeling the drug manufacturing firm that is exposed to supply chain disruption risk. The firm determines optimal RMI levels for assumed Dual Sourcing and Agility Capacity. We quantify the decrease in RMI levels in the presence of Dual Sourcing and Agility Capacity. Furthermore, using an example, we analyze RMI, Dual Sourcing and Agility Capacity decisions jointly. It turns out that RMI and Agility Capacity can be substitutes as long as no Dual Source is available. Once the Dual Source is available, Agility Capacity and Dual Sourcing appear to be substitutes. We further show that for long disruption times, the optimal Dual Source production rate may decrease in the disruption time. Within our modeling framework, we introduce an operational metric that quantifies Supply Chain Resilience. Supply chain disruptions can have a severe business impact and need to be managed appropriately.     

Fiber optical network design problems: A case for Turkey

In this paper, we consider problems originating from one of the largest Internet service providers operating in Turkey. The company mainly faces two different design problems: the green field design (area with no Internet access) and the copper field re-design (area with limited access over copper networks). In the green field design problem, the aim is to design a least cost fiber optical network that will provide high bandwidth Internet access from a given central station to a set of aggregated demand nodes. Such an access can be provided either directly by installing fibers or indirectly by utilizing passive splitters. Insertion loss, bandwidth level and distance limitations should simultaneously be considered in order to provide a least cost design to enable the required service level. In the re-design of the copper field application, the aim is to improve the current service level by augmenting the network with fiber optical wires, specifically by adding cabinets to copper rings in the existing infrastructure and by constructing direct fiber links from cabinets to distant demand nodes. Mathematical models are constructed for both problem specifications. Extensive computational results based on realistic data from Kartal (45 nodes) and Bakırköy (74 nodes) districts in Istanbul show that the proposed models are viable exact solution methodologies for moderate dimensions.     

专利法的若干问题及其立法建议

专利法的两次修正使我国专利保护水平在整体上得到了历史性提升。但是 ,某些具体规则的内容尚有值得探讨之处。专利法与合同法对合作发明创造的权利归属规则应协调一致 ;专利申请权与申请专利的权利性质不同 ,转让程序也不同 ,两者不能混淆 ;外观设计专利授权条件中的美感应改为装饰性 ,以反映外观设计的本质特点
