基于引文内容分析的引用情感识别研究

［目的/意义］针对自动识别论文引用情感问题，提出一种基于引文内容分析的识别方法并进行可视化展示，克服基于简单引用频次计量无法区分不同引用情感的问题。［方法/过程］首先，利用正则表达式抽取出论文全文中的引文内容信息; 然后，利用 TF-IDF 算法筛选出引用情感特征词，结合情感词典，利用情感分析技术对引文内容进行引用情感识别; 最后，利用可视化工具展示出引用情感整体分布情况。［结果/结论］该方法能够有效识别出抗衰老领域论文数据集中引用情感情况。实验结果显示，该领域正面引用占总引用次数的21% ，中立引用占总引用次数的 78% ，负面引用仅占总引用次数的 1% 。与传统引文网络相比较，基于引用情感的可视化图谱可以有效识别出不同引用情感在整体数据集合上的分布情况。</p

China’s Coal Net Imports Forecast and the Energy Strategy Adjustments under the Trend of Coal Net Import

一直以来，煤炭都是中国一次能源消费中最主要的能源品种，中国高速经济增长的主要能源动力是廉价的煤炭资源。到目前为止，依然有很多人认为中国的煤炭资源是取之不尽用之不竭的。本文利用Hubbert峰值模型对中国的煤炭峰值进行了刻画，表明即使采用基础储量数据，即不考虑回采率的限制，中国煤炭峰值也会在2036-2040之间到来，产量为48-58亿吨原煤，之后中国的煤炭产量会进入快速下降的通道。另外，本文还对影响中国煤炭产量峰值的影响因素进行了分析，包括储量、回采率和政府的政策。中国高速的经济增长带来了中国煤炭消费的大幅增加，本文建立了包含一次能源消费需求和GDP、能源效率、能源价格水平、产业结构等变量关系...All along, coal is the most important energy varieties of the primary energy consumption in China. And the cheap coal resources are the main energy power of China’s rapid economic growth. Up to now, there are still a lot of people who hold the view that China's coal resources are inexhaustible. This article uses Hubbert model to depict the coal peak in China, which indicates that even with the bas...学位：经济学博士院系专业：经济学院中国能源经济研究中心_能源经济学学号：3132008015030

Modulation Recognition Method of Non-cooperation Underwater Acoustic Communication Signals Using Principal Component Analysis

由于信道传输特性、信噪比低等因素的影响,非合作水声通信信号的调制识别极具挑战性。对信号功率谱、平方谱进行主分量分析,提取代表不同类型调制信号特有信息的主分量作为特征参数,从而降低特征参数维度、抑制噪声影响,并在此基础上设计一种基于人工神经网络的水声通信信号调制方式分类器。海上实录信号数据的识别实验结果表明了该方法的有效性。The modulation classification of the non-cooperation underwater acoustic communication signals is extremely challenging due to channel transmission characteristics and low signal-to-noise ratio. The principal component analysis( PCA) is used to analyze the power spectra and square spectrum features of signals,which is capable of extracting the principal components associated with different modulated signals as input vector,thus reducing the feature dimension and suppressing the influence of noise. An artificial neural network( ANN) classifier is proposed for modulation recognition. The experimental modulation classification results obtained from field signals in 4 different underwater acoustic channels show that the proposed modulation recognition method has good classification performance.国家自然科学基金项目(11274259、11574258

经营“灵活性”:制造业劳动力市场的组织生态与制度环境——基于W市劳动力招聘的调查

对于世界工厂如何持续有效地组织和控制劳动力问题,当前研究过于关注生产政治,忽略了工厂之外劳动力市场组织的角色与影响。基于对W市制造业招聘的调查,本文分析了当前劳动力市场组织生态及其嵌入的制度环境。研究表明,围绕企业的灵活用工需求,劳动力市场组织形态日益复杂化,已形成了层层外包、精细分工、竞争合作的中介链条。在配合弹性生产的同时,该链条的盈利方式与运行策略正不断抬高工厂的用工成本,持续构造工人的高流动性与低技能性。地方政府、用工企业、工人群体是形塑劳动力市场组织生态的重要力量,三者共同营造了中介链所需的制度环境,并策略性地经营着生产体系中部分的\"灵活性\",同时也放大了生产体系整体的系统性风险。中央高校基本科研业务费(ZK1044);;\n福建省社会科学规划青年项目(FJ2017C050)的阶段性成
