舆情内涵发展演变探析

舆情研究是在吸收借鉴舆论与民意相关研究的基础上发展起来的,舆情概念的提出和舆情研究的发展反映了我们党科学执政、民主执政的现实要求,突出舆情的政治指向性,具有重要的现实意义。而随着转型期社会利益矛盾的复杂化、公民社会力量的增长和网络表达的快速发展,网络舆情在整个社会舆情中的地位和影响日益凸显,舆情的内在诸要素也在不断发生变化,因而舆情概念的内涵与外延也应不断做出相应的调整、丰富与拓展。

精神病人强制医疗程序法律制度评析

长期以来,对肇事肇祸精神病人的强制收治,一般由公安机关以行政手段决定.《刑事诉讼法》的修订,将强制医疗程序纳入司法轨道,但缀加了“依法不负刑事责任”的限定条件.《精神卫生法》则立足于行政手段对精神障碍患者的收治管理进行了规定.虽然两部法律的规定更多是宏观上的制度构建,但有理由肯定其划时代的巨大意义,并有必要对相关内容进行解构和研究.     

网络广告的价值取向分析

作为一种文化传播形式,网络广告是社会价值观念不断被传送、强化和公众接受社会文化教化的过程。目前网络广告呈现出多种价值取向,积极价值取向主要体现在弘扬民族精神和社会公德、张扬个性、鼓舞斗志,消极的价值取向体现为重利轻义思想严重、宣扬享乐主义、网络色情广告泛滥、挑战社会公德等,成为互联网世界中最不安定的因素之一。造成这些现象的主要原因是：部分广告主和网站经营者片面追求利益最大化、中国传统价值观与西方价值观的冲突、网络经济的发展与法律法规相对滞后的矛盾、行业规范的缺失与技术监控的瓶颈、从业人员缺乏道德素养与受众的主体意识退化等。     

基于驱动因素控制的线性时变参数DLDGM(1,N)模型

针对传统GM(1,N)模型未考虑参数随时间变化的动态特征及未明确驱动因素作用机制的问题,首先引入线性时变参数以及驱动因素控制函数,构建基于驱动因素控制的线性时变参数DLDGM(1,N)模型,论证DGM(1,1)、NDGM(1,1)、TDGM(1,1)、DGM(1,N)、DCDGM(1,N)模型均是该模型在不同参数取值下的特殊形式;然后基于白化信息充分和匮乏的两种情况,给出驱动因素控制参数的识别方法;最后应用所提模型对河南省粮食产量进行预测,验证模型的有效性和实用性。     

基于柯式模型的残疾人就业培训效果评估

为及时发现现有残疾人就业培训体系的不足,从而在理论上和实践上提供有针对性的对策建议,本文在柯式模型的基础上,将全国范围内参加就业培训或接受就业支持的残疾人作为研究对象,以问卷法和访谈法相结合的方式收集数据,经由专家评价和统计处理后编制出残疾人就业培训效果评估问卷,并进一步探索年龄、婚姻状况、地域和就业形式等显著影响残疾人培训效果的因素.此外,研究还发现就业培训效果与残疾人培训满意度、月收入显著正相关;而除了农业户口种养殖就业形式的残疾人以外,八种就业形式和无就业残疾人的培训满意度与培训效果总均分均存在显著正相关.     

Bin packing with “Largest In Bottom” constraint: tighter bounds and generalizations

The (online) bin packing problem with LIB constraint is stated as follows: The items arrive one by one, and must be packed into unit capacity bins, but a bigger item cannot be packed into a bin which already contains a smaller item. The number of used bins has to be minimized as usually. We show that the absolute performance bound of algorithm First Fit is not worse than 2+1/6≈2.1666 for the problem, improving the previous best upper bound 2.5. Moreover, if the item sizes do not exceed 1/d, then we improve the previous best result 2+1/d to 2+1/d(d+2), for any d≥2. (Both previously best results are due to Epstein, Nav. Res. Logist. 56(8):780–786, 2009.) Furthermore, we define a problem with the generalized LIB constraint, where some incoming items cannot be packed into the bins of some already packed items. The (in)compatibility of the incoming item with the items already packed becomes known only at the arrival of the actual item, and is given by an undirected graph (and, as usual in case of online graph problems, we can see only that part of the graph what already arrived). We show that 3 is an upper bound for this general problem if some natural transitivity constraint is satisfied.     

高层管理支持、环保创新实践与企业绩效——资源承诺的调节作用

本论文基于珠三角地区148家制造企业的问卷调查,对高层管理支持、环保创新实践与企业绩效之间的关系进行实证研究,并进一步验证资源承诺对环保创新实践与企业绩效之间关系的调节作用。研究结果显示:高层管理支持对环保创新实践有显著的正向影响,环保创新实践显著正向作用于企业的环境绩效,但对企业经济绩效没有显著的直接作用,而是会通过环境绩效间接地作用于企业的经济绩效。此外,研究还发现资源承诺对环保创新实践和企业经济绩效之间的关系有正向调节作用。     

Uneven dynamics and regional disparity of multidimensional poverty in China

Qualifying the official minimum of “Two no worries and three guarantees” (certainty of food and clothing, guarantees of compulsory education, basic medical care, and housing) is essential to evaluate the targeted poverty alleviation program since 2013 in China. Using the poverty monitoring dataset and the multidimensional poverty indicator system, the uneven dynamics and regional disparity of multidimensional poverty and its driving factors in poverty-stricken areas in China during 2014–2018 are explored in this paper. The incidence rate of multidimensional poverty was reduced by 61.72%, and the poverty reduction rate within the six dimensions ranged from 52.29 to 76.36%. Multidimensional poverty and its six dimensions displayed narrowing regional disparity. Impoverished and moderately poor areas shrank, whereas low-poverty areas expanded. All 22 provinces have become low-poverty areas in 2018. The contribution of each dimension to multidimensional poverty varies for different types at different stages. Income and expenditure contribute the most to poverty status, followed by transportation, housing conditions, education, communication, and medical care and health. The contribution of each indicator among different dimensions varied with different trends from 2014 to2018. This paper helps incorporate the official minimums of “Two no worries and three guarantees” into a more operational evaluation system to promote sustainable policies for governments at all levels by 2020 and beyond, as well as provide valuable references for poverty alleviation in other developing countries worldwide.

     

论中国大地上的知识青年上山下乡运动

20世纪60年代末文革中兴起的全国性大规模知识青年上山下乡运动,由初始的安置青年学生就业的权宜之计,迅速发展成为“反修防修”、培养无产阶级革命事业接班人的百年大计。其间出现了一系列知识青年的生活生计、生产劳动的实际问题,他们的心态由此出现反复,并形成了社会的共鸣。党和国家进行了多次的政策性调整。这场运动从轰轰烈烈兴起经十年到悄然偃息之后,给人留下了多重的思索:知识青年上山下乡是大有作为;还是有所作为;或是无所作为?只有以实践来检验之,并总结出历史的经验和教训。
