论网络称呼语“亲”的泛化

"亲"是2011年十大流行语之一,它不仅在网上流行而且也已经进入了我们的生活。它不反映人们彼此间的各种关系及所拥有的社会评价,所以本文认为"亲"属于称呼语。我们搜集了"亲"泛化的各种表现,并且对它的词义进行考察分析,认为"亲"是"亲爱的"缩略形式。从淘宝购物、交际需求、称呼语的缺失和社会功能这四个方面分析了"亲"泛化的原因,并且对它的发展前景进行了预测。     

明代科举格局与士人出处

科举制度对明代社会文化有着极为深刻的影响，作为士子人生穷达的关键转折，科举制度为传统观念下“学优则仕”的人生理想提供了相对客观有限的实现保障，士行文风为之转移。但其中各种各样的流弊、有限的录取名额又将相当多的士子拒之门外，因各种原因被迫放弃科举的失意文士以传统恩路中的“无道而隐”应对进取受挫的精神压力，因个人际遇而形成了一代以“隐”为主导色彩的士人风流。     

Amplitudes, rates, periodicities and causes of temperature variations in the past 2485 years and future trends over the central-eastern Tibetan Plateau

Amplitudes, rates, periodicities, causes and future trends of temperature variations based on tree rings for the past 2485 years on the central-eastern Tibetan Plateau were analyzed. The results showed that extreme climatic events on the Plateau, such as the Medieval Warm Period, Little Ice Age and 20th Century Warming appeared synchronously with those in other places worldwide. The largest amplitude and rate of temperature change occurred during the Eastern Jin Event (343-425 AD), and not in the late 20th century. There were significant cycles of 1324 a, 800 a, 199 a, 110 a and 2-3 a in the 2485-year temperature series. The 1324 a, 800 a, 199 a and 110 a cycles are associated with solar activity, which greatly affects the Earth surface temperature. The long-term trends (>1000 a) of temperature were controlled by the millennium-scale cycle, and amplitudes were dominated by multi-century cycles. Moreover, cold intervals corresponded to sunspot minimums. The prediction indicated that the temperature will decrease in the future until to 2068 AD and then increase again.

Dispatch Liquidity Theory in a Deregulated Environment

Power system security and reliability are more complex issues in a deregulated environment.Various criteria have been considered for power system reliability. In the day-ahead market, a successful trade schedule should be able to accept various disturbances with sufficient flexibility to be adjusted during the re-dispatch process. This paper describes the dispatch liquidity theory and some liquidity indices. The liquidity indices evaluate the effective operating reserves with the network constraints taken into consideration. A model is presented to calculate the liquidity index. An extended trade scheduling model with minimum liquidity index constraints is presented that considers the distribution requirements of the operating reserves. The liquidity indices could also be used to coordinate the security and reliability between multistage markets and for contingency selection. The algorithms were tested with real power system data. The results show that the dispatch liquidity theory is reasonable and the algorithms are effective.     

基于非线性映射分析的期货逼仓风险判定模型及其应用

选用资金、价格、持仓量等三类指标来反映期货交易中的逼仓风险,采用非线性映射分析将交易中存在逼仓风险的交易日分离成独立的点群.根据离差极小、最大欧氏距离等原理提出逼仓风险阈值计算方法及逼仓风险判定方法.其特点一是运用非线性映射分析等原理给出了逼仓风险阈值的求解方法及风险判定方法,使逼仓风险在酝酿初期就可被及时、准确地判定出来,为期货交易逼仓风险管理提供了预警功能.二是通过与系统聚类结果的对比,验证了非线性映射分析方法的科学性和有效性.三是以豆粕s0409的244个有效样本作为总样本,举例说明了逼仓阈值的求解及风险判定过程.并随机抽取了该合约中的30个样本进行检验,检验结果表明该判别方法的精度高达93.33%.

陕西省现代服务业发展面临的机遇

现代经济以服务业的高度发达为标志。服务业的现代化程度是衡量一个国家和地区现代化水平的重要指标。由于陕西经济总体发展水平低,现代服务业发展总量不足,有很大的发展空间。为此,应抓住全面建设小康社会及服务业开放和服务业国际转移的有利时机,充分利用我省科技教育等优势资源,促进我省现代服务业的发展。     

窃取商业秘密获得的专利权归商业秘密权利人所有——兼谈商业秘密构成要件和范围

中国加入WTO以后,知识产权的保护意识日益强化,作为知识产权范畴的专利权更是被人们普遍关注和重视。以“错案”为研究对象,运用商业秘密的有关理论以及保护商业秘密和专利权的有关法律制度,特别是从窃取商业秘密获得的专利权归谁所有的角度,对人民法院的判决进行了分析研究,指出了人民法院的判决是错误的,提出了窃取商业秘密获得的专利权归商业秘密权利人所有。这有利于人民法院公正司法,依法审判。
