Design and Implementation of the O2O Platform on Mobile Internet for a Community
随着经济发展与商业形态的变迁,社区居民对于社区商业、社区服务需求逐步增大。O2O作为线上流量与线下销售协同的一种服务展现形式,充分发挥了网络购物便捷和实体商户商品真实的特点,特别适用于社区服务。社区O2O即在传统O2O的基础上,面向同一区域内用户开展线上流量与线下购买互通服务。 本文通过对社区O2O业务特点与技术需求的深入分析,规划了系统技术架构。同时,针对移动互联网的特性,以及社区O2O中社区服务、社区商业、社区社交三大业务模块各自不同的业务需求,对系统的逻辑架构、子模块、数据库进行了详细的设计,规划了表示层、接入层、领域层、通用系统与数据层五个系统层级,以及各类第三方平台的接入与功能调用...With the development of economy and the change of business form, community residents' demand for community commerce and community service is increasing gradually.

Environment, Resources and Fisheries Society: A Case Study of Jiaodong’s Coastal Region in the 1950s
本文以20世纪50年代的胶东渔场为中心,考察与之相关的渔权争端、产业开发、自然灾害、资源保护、政治改革以及妇女角色的演变,揭示环境、资源与社会的相互依赖与内在关系,进而就某些问题提出新的观点与思考。 在西方学者笔下,“海上公地”的核心问题是短期和局部的生态恶化。而黄海的渔业争端却经历了漫长的演变史:从宗藩时代的越海捕鱼活动,到殖民体系下的实业救国与政府谈判,再到当代的军事护渔和技术竞争。受到资源波动、国力博弈与技术发展的影响,公地的位置、范围和性质在不断改变着,这种变化本身带有长时段和跨区域的历史延续性。 渔业转型离不开成功的资源开发活动,荣成地区的捕鲨计划就是其中之一。政府在资源禀赋的基...The paper is focusing on the fishery transformation in Jiaodong during the 1950s, including fishing disputes, development activities, natural disasters, resources protection, political reform and gender relations. Our objective is to emphasize the contingent interdependence between environment, resources and human society. At the heart of this study Garrett Hardin’s “tragedy of the commons” is th...学位:历史学博士院系专业:人文学院_专门史学号:1032012015370
Directed Evolution and Simultaneous Release Reasearch of Recombinant Cellulases
能源短缺和环境污染是我国乃至全球可持续发展面临的两大挑战。随着人口的增加和现代化工业进程的持续发展,有限的不可再生的煤炭等化石能源已无力支撑世界对于能源的巨大需求。开发新的、清洁环保的、可持续的替代能源,成为解决这两大挑战的主要方案。利用大自然中广泛的生物质为前体,经过一定的转化和利用,将储存在其中的太阳能变成燃料等可以直接利用的能源,同时在此过程中可以得到一定的化学品,这种生物炼制的理念被科学界广泛接纳并加以实践。木质纤维素作为地球上蕴藏最丰富的生物质资源,一直是生物质能研究的重点,通过纤维素酶,将木质纤维素降解成糖,然后经过发酵等生物转化生成最终的生物质燃料是一条行之有效的利用途径。 纤...Energy shortage and environmental pollution are two of main challenges to human being in sustainable development in China and the whole world. With the increase of population and the sustainable development of modern industrial process, a limited non-renewable fossil fuels such as coal has been unable to support the huge demand for energy in the world. To developing the new, clean, environmental p...学位:工学硕士院系专业:化学化工学院_生物化工学号:2062013115146

Analysis on the Misconceptions of the Subject of National Defense Education
国防教育主体是国防教育学科的基本研究范畴,也是国防教育实践需要明确的根本问题。明确国防教育主体的内涵以及各主体之间的关系,是正确发挥国防教育主体作用,提高国防教育效率的基本要求。 国防教育主体是包括政府、武装力量、社会团体、各政党、企事业组织以及全体公民在内的广义的“国家”,具有国防和教育的双重属性。国防教育主体的特征主要有:结构上的多层次性,领导角色的更替性,利益的多元性以及矛盾的复杂性。国防教育主体的理论误区,一是国防教育的领导主体与实施主体不可兼任;二是公民不可作为国防教育的主体;三是国防教育主体领导角色的更替会导致无政府领导。实践中对国防教育主体的认识误区,一是对“国家”的概念模糊;...The subject of national defense education is among the basic researching category of national defense discipline, as well as the fundamental question that needs to be clarified in national defense practice.

TEAD4 as a Potential Therapeutic Target for Hepatic Carcinoma and Colon Cancer
肝癌和结肠癌是常见的恶性肿瘤,发现时往往已经到了晚期,因而这两种肿瘤都有较高的致死率。因此,迫切需要为结肠癌和肝癌的早期诊断寻找标志物,并为结肠癌和肝癌的治疗提供更有效的新靶点,筛选出合适的药物进行治疗。 Hippo通路效应蛋白---TEAD蛋白家族成员在哺乳动物中高度保守,其家族有四个成员,包括TEAD1,TEAD2,TEAD3以及TEAD4。该家族成员共有的特征是包含TEA结构域(DNA结合结构域)以及能够与转录激活因子结合的转录激活结构域。TEAD蛋白家族在辅转录激活因子的参与下能将信号向下游传导,影响细胞分化、增殖、抗凋亡以及干细胞的干性维持等方面的功能。其中,TEAD4可通过激活C...Colorectal cancer (CRC) and hepatocellular carcinoma (HCC) are most common causes of cancer-related death wordwide. Therefore, it is important to discover novel biomarkers for early detection, and to identify novel target for treatment of CRC and HCC patients.

Resource Endowments,Policy Orientation and Social Effects:The Shark-Fishing Plan in Rongcheng during the 1950s
1950年代,山东荣成地区曾发展过一项捕鲨计划。当地的一批尚未公开的渔业档案记录了该计划的实施细节,并且提供了新的评价资源开发方式与效应的维度:在产业发展过程中,资源禀赋要素直接影响到官方的政策导向,当渔民从事捕鲨业时,政府在环境与产业特征基础上,对资本和流通环节进行过某种程度的引导和干预;从开发的社会效应上看,捕鲨业自身并没有陷入一个雷同的“开发—破坏“怪圈里,其发展是与渔民生产方式和渔村职业结构的变化相联系的。In 1950s, Rongcheng County of Shandong Province has developed a shark-fishing plan.Some undisclosed archives about the local fishery recorded the details of the whole plan, which provided a new perspective of evaluating the resource development mode and its effect: In the process of development, the resource endowments directly affected the policy orientation.When fishermen joined the plan, the government made some guidance and used some intervention on the capital link or the circulation, which were based on the environment and industry characteristics.On the social effects, the shark-fishing plan itself has not fallen into a duplicate trap of "development-damage", whose development was associated with the changes of the fishermen's production mode and the fishing villages' professional structure
