校园媒体对大学校园文化建设的功能探析

校园媒体对大学校园文化建设的主要功能是舆论引导功能和文化上的同构建设功能。深受世界范围内媒体环境变革的影响,校园媒体对校园文化建设的功能面临新挑战。为应对这一挑战,校园媒体在舆论引导功能上要加强舆论导向与传播效果的统一、党性原则与受众意识的统一;在媒介文化建设上要深入研究“三贴近”方法,办有亲和力的校园权威媒体。本文同时还探讨了新形势下校园媒体新作用的正负效应及相应对策。     

领导成员交换关系对企业员工管家行为倾向的影响研究

通过问卷调查,采集针对企业普通员工的问卷数据,探讨了领导成员交换关系与员工管家行为之间的关联关系,构建并检验了 “领导成员交换关系—心理所有权—员工管家行为倾向”作用机制模型。研究结果表明：领导成员交换关系对员工管家行为倾向有显著的正向影响,心理所有权在领导成员交换关系与员工管家行为倾向之间起部分中介作用。     

数字化发展、制度环境与政府舆情治理质量

基于2016—2020年我国31个省级行政区的面板数据,考察数字化发展、制度环境与政府舆情治理质量之间的关系。研究发现,数字化发展对政府舆情治理质量具有改善效应;相比制度环境较差的省份,数字化发展对舆情治理质量的改善效应在制度环境较好的省份更为显著。异质性检验表明,数字化发展对政府舆情治理质量的改善效应在数字化水平高的省份、制度环境较好但数字化水平低的省份显著,在制度环境较好的省份、制度环境较差的东部省份显著。研究结论为借助数字化发展改善政府舆情治理质量提供了理论依据。     

Double robust estimator in general treatment regimes based on Covariate-balancing

Double robust estimators have double the chance of being a consistent estimator of a causal effect in binary treatments cases. In this paper, we proposed an estimator of a causal effect for general treatment regimes based on covariate-balancing. Under parametrical situation, our estimator has double robustness.     

The effect of media sexism on women’s political ambition: evidence from a worldwide study

This paper presents results from one of the first global studies on the relationship between media sexism and the share of candidates for the lower chamber of national parliaments who are women. Data on media sexism come from the Global Media Monitoring Project, the most reliable worldwide source for media coverage from a gender perspective. The data on share of female political candidates come from the Inter-Parliamentary Union. The results show that that there is, even when controlling for the number of women in parliament, electoral system, gender quotas, level of human development, level of women’s rights, freedom from corruption, and media access, a significant relationship between media sexism—measured as (i) the share of all news subjects that are women and (ii) the share of all news subjects portrayed in the function of experts who are women—and the share of women candidates for parliament: the higher the level of media sexism, the lower the share of women candidates. The theory discussed zooms in on a bystander effect: We hypothesize that sexist portrayals of women in the media stifle ambition among women who, in a less sexist media environment, would be willing to stand as political candidates.     

Education,cognitive ability,and cause-specific mortality: A structural approach

Education is negatively associated with most major causes of death. Prior work ignores the premise that cause-specific hazards are interdependent and that both education and mortality depend on cognitive ability. We analyse Swedish men aged 18–63, focusing on months lost due to specific causes—which solves the interdependence problem—and use a structural model that accounts for confounding due to cognitive ability. In a standard Cox model controlling for Intelligence Quotient, improving education is associated with large decreases in mortality for major causes of death. In the structural model, improving education is associated with a small decrease in months lost for most causes and education levels. Among the least educated, however, improving education strongly reduces the months lost, mainly those lost from external causes, such as accidents and suicide. Results suggest that conventional analysis of education and mortality may be biased, even if accounting for observed cognition.     

基于复杂网络的电动汽车充电桩众筹市场信用风险建模与分析

因其经济优势及环境友好特性,电动汽车（EV）保有量持续攀升。而当前中国充电设施建设明显滞后于电动汽车的扩张速度,成为制约电动车发展潜力的主要瓶颈。由于充电设施具有高正外部性,同时投资回收期较长,难以吸引到传统融资,而基于互联网的众筹作为新型融资方式则受到了广泛关注。但由于缺乏强制性的信息披露制度及相关法律法规,众筹融资过程中的信息不对称问题相较传统融资方式更为严重,由此导致的高违约率也进一步削弱了投资者信心。本文利用复杂网络对电动汽车充电桩众筹融资市场进行建模,刻画了众筹投资者决策过程中的羊群效应,基于信息不对称使用多Agent模型对信用风险的产生、影响及针对性政策效果进行了模拟分析。结果表明,众筹投资者在决策过程中易受到社交网络中负面信息的影响,使得筹资人违约行为的不利影响进一步扩散。而严格的罚款机制可以在不影响融资市场均衡的情况下,使违约行为的恶性循环得到遏制。     

微信公众号影响力指数建构与量化评估

作为被广泛使用的社交媒体,微信已经成为热点事件和网络舆情的重要策源地,科学准确评估微信公众号的影响力对于明晰微信信息传播特点,深入挖掘微信传播潜力,进一步规范和指导微信平台的传播行为具有较大的理论和实践意义。在对既有关于微信公众号影响力研究进行梳理和评价的基础上,基于传播效果测量的设计,坚持以受众为中心、由浅入深多层次考察准则,运用德尔菲法和层次分析法建构一套微信公众号影响力指标体系。该指标体系由4个一级指标和9个二级指标构成,并运用线性合成法合成微信公众号影响力指数。     

社会资本视角下“以购代捐”精准扶贫模式研究 ——基于凉山彝族自治州的实证分析

以凉山彝族自治州在精准扶贫过程中,为破解贫困地区“孤岛效应”,探索“以购代捐”扶贫模式为例,基于社会资本导向 的反贫困治理策略,分析“以购代捐”扶贫模式的理论内涵、演进路径、模式创新等,提出“以购代捐”正面临,物流投入滞后,影 响农产品品质;质量标准缺乏,制约农产品价格;质量检测缺位,食品安全堪忧;产品价格缺乏优势,长期执行易陷入行政摊派 等现实问题,为了完善“以购代捐”精准扶贫模式,建议：一要调动贫困农户生产积极性,保证农民“爱种（养）”;二要合理兼顾帮 扶单位的利益,让对口帮扶单位“爱吃”;三是政策措施要简单易行,让行政主管部门“爱扶”。     

论政府对会计监管的必要性、缺陷和效果

政府会计监管对纠正市场失灵、重新配置社会经济资源和调节经济运行有显著效果。同时 ,也存在严重缺陷 ,其表现为 :政府垄断会计规范制定权导致政府行为低效率 ;政府监管目标多元化导致政府角色冲突 ;政府会计监管部门行动不协调导致会计监管效率下降。政府会计监管要适度 ,监管不足和监管过度都是监管效果低下的表现。我国会计监管的现状是监管不足和监管过度两者并存
