在当代中国政治经验中,人民是中国共产党和广大群众密切结合在一起的政治实体力量,是全过程人民民主的根本主体。就理论逻辑而言,作为根本主体的人民在政治生活中发挥着作为整体性质的政治实体的作用,不仅由人民掌握国家权力,并定型为国家制度,而且由国家权力机关来代表人民,真正的将人民当家作主落实到全过程人民民主的实践之中。就历史脉络而言,人民是中国共产党通过组织、动员、教育等方式,将广大群众团结在自身领导之下,从而塑造的能够推动历史进步的积极力量,中国共产党既塑造人民又代表人民,并且使人民作为整体性质的政治实体力量存续于全过程人民民主的实践之中。就实践形式而言,中国共产党是内在于人民之中的领导力量,民主党派、人民团体、群众组织等都是人民的重要组成部分,在中国共产党的领导下形成“多元一体”的政治实体即人民,推动着全过程人民民主的发展与深化。

基于反事实思维,利用2000-2020年中国14个省份的面板数据,采用广义合成控制法探究“价补分离”政策改革对玉米生产的影响效果。结果表明,“价补分离”政策的实施促使实施地区玉米产量增加了183.01×10^(4)t,增产贡献为6.69%。“价补分离”政策具有时空异质性,2016年政策增产贡献较2015年降低了82.7%,随后逐年提升,2019、2020年政策效果趋于稳定。因生产者补贴政策制定标准、补贴对象范围等不同,3个实施地区玉米生产者补贴政策对玉米生产的影响效果存在差异,增产效应由高到低依次为黑龙江、内蒙古、辽宁、吉林。基于此,提出政府与市场有机统一、细化补贴对象范围、实施差异化标准补贴的政策建议。

路网中的skyline查询在智慧交通、兴趣点发现和位置服务等领域具有重要的应用价值,但存在查询效率较低、未考虑查询结果的隐私性等问题。有鉴于此,文中提出了一种基于差分隐私的路网环境下skyline查询方法。首先,针对路网环境下的初始数据集数据量大和数据复杂的特点,对数据集进行预处理,利用基于距离属性划分的skyline层和路网Voronoi图的性质提出了3个剪枝规则,基于剪枝规则给出了路网环境下的数据集剪枝算法,从而有效地过滤掉大量冗余数据;其次,针对过滤后的数据集,利用网格索引的存储方式来节省存储空间,并设计了基于网格索引的skyline扩展树,基于扩展树和相应的剪枝规则提出了查询全局候选skyline点集的算法;最后,针对查询结果集,利用差分隐私预算分配模型来分配隐私预算,并基于信息散度进行结果集发布,有效提高了数据信息的隐私性。实验结果表明:所提出的查询方法的准确率在99%以上;其在数据集规模较大情况下的查询效率相较于传统skyline查询方法提升10%以上;在总差分隐私预算为0.01、0.10、0.50和1.00时,所提出的隐私预算分配方法的相对误差均低于等差分配和等比分配方法。

为了解决时序知识图谱的存储问题,提出结合快照和日志模式的时序知识图谱存储模型SL-tgStore.模型由若干时间桶组成,每个时间桶由一系列的时间窗口组成.在首个时间窗口引入初始快照作为时序知识图谱存储和处理的基本单元,在接下来的时间窗口存储为增量日志.提出相应的阈值来确定初始快照的生成,即生成一个新的时间桶,以达到初始快照数量与增量日志数量的平衡,并提出临时快照生成算法.所提模型能够有效解决快照存储模式消耗内存大,日志存储模式查询效率低的问题.为了对SL-tgStore模型进行高效查询,在此基础上提出4种索引结构.在4个真实数据集上进行实验,理论研究与实验结果表明所提出的SL-tgStore存储模型具有高效性.
