“We wouldn’t say it to their faces”: online harassment,women sports journalists,and feminism

In April 2016, a US-based independent sport media organization Just Not Sports launched #MoreThanMean, a digital media campaign to raise awareness about online harassment of women in sports journalism. The video quickly reached 3.7 million views and generated widespread coverage in mainstream news media, sports media, and online-only outlets. Using the #MoreThanMean campaign as a case study, this study assesses how discourses circulate in the sports media environment and, in particular, how feminist messages travel as the content moves from social media to mass media. This study engages with post-feminism in order to examine how various producers of media content position online harassment and sexism in sport and society. While the campaign positioned online harassment as gendered workplace discrimination, the mainstream and sports media coverage typically centralized men in the discussion. Feminist perspectives were constrained to platforms with a progressive, women-centered, and/or explicitly feminist take. Implications for digital feminist activism in the context of sport are discussed.     

数字经济发展的评估指标体系研究——基于投入产出视角

发展数字经济是我国重要国策,对其评估指标体系的研究受到多方关注,但目前我国数字经济测度仅仅局限于数字化产业和数字化创新,尚未形成一个完整、系统的数字经济评价指标体系。文章在引入治理环境的基础上,基于经济学上的投入产出视角探讨我国数字经济发展的有效测度方法,在研究数字经济的发展效应中新添了数字化治理和数字知识型人才供给两项指标,构建了一套基于投入产出视角的数字经济发展评价指标体系,为衡量数字经济发展提供了一个系统的体系。为提升数字治理现代化水平,更好发挥数字经济在促进经济高质量发展中的作用提供了实践意义和政策参考。     

A multicriteria sorting approach based on data envelopment analysis for R&D project selection problem

In this paper, multiple criteria sorting methods based on data envelopment analysis (DEA) are developed to evaluate research and development (R&D) projects. The weight intervals of the criteria are obtained from Interval Analytic Hierarchy Process and employed as the assurance region constraints of models. Based on data envelopment analysis, two threshold estimation models, and five assignment models are developed for sorting. In addition to sorting, these models also provide ranking of the projects. The developed approach and the well-known sorting method UTADIS are applied to a real case study to analyze the R&D projects proposed to a grant program executed by a government funding agency in 2009. A five level R&D project selection criteria hierarchy and an assisting point allocation guide are defined to measure and quantify the performance of the projects. In the case study, the developed methods are observed to be more stable than UTADIS.     

R2的复活——股价同步性研究评述与展望

R2是最近十几年迅速发展的一个研究课题,其研究取向从纯粹的计量经济学符号演变为股价同步性特征变量,并与公司特质信息含量联系起来,赋予了全新的内涵.学者们通过跨学科的交叉与融合,从法与金融理论、委托代理理论、信息不对称理论、公司治理理论等视角对R2背后的生成机制、作用渠道和影响后果展开富有成效的研究.本文首先梳理从资产定价模型到R2,再从R2到股价同步性中间的学理关系和因果顺承,接着回顾了关于R2形成机理与经济后果的相关讨论,然后对R2的学术争论进行总结和评述,最后就R2的溯源问题、以及文化与政治潜在影响对未来R2研究提出展望.     

P2P 网络借贷研究进展及中国问题研究展望

P2P ( 个人对个人) 网络借贷是指通过网络借贷平台,在全球范围内实现个人与个人或小微企业间的小额信用借贷交易． P2P 网络借贷作为全新的互联网金融服务受到商业界的高度关注,而且发展成为学术研究的国际前沿领域． 对 P2P 网络借贷相关研究文献进行了综述,具体从影响借贷交易的信息因素、羊群效应以及社交网络等 3 个方面分析了该领域研究的现状和发展脉络． 因为中国已超越美国成为全球最大的 P2P 网络借贷交易市场,所以结合中国的具体情境和问题,提出了未来研究工作的展望．     

中国P2P网络借贷信用风险的测量

分析中国P2P网络借贷信用风险的生成机理,借鉴商业银行典型个人信用风险测量理论基础与方法,构建基于涵盖借款人软信息的P2P网络借贷信用风险评级指标体系。通过向在银行从事信贷工作的专业人员发放调查问卷,确定具体指标,使用AHP(层次分析法)与DEMATEL(决策实验室法)相结合的方法综合确定指标体系权重,最后评级结果以百分制数值给出,并换算成具体的信用等级,有效解决了平台对借款人信用等级测量问题。     

A powerful and efficient algorithm for breaking the links between aliased effects in asymmetric designs

Fractional factorial (FF) designs are no doubt the most widely used designs in experimental investigations due to their efficient use of experimental runs. One price we pay for using FF designs is, clearly, our inability to obtain estimates of some important effects (main effects or second order interactions) that are separate from estimates of other effects (usually higher order interactions). When the estimate of an effect also includes the influence of one or more other effects the effects are said to be aliased. Folding over an FF design is a method for breaking the links between aliased effects in a design. The question is, how do we define the foldover structure for asymmetric FF designs, whether regular or nonregular? How do we choose the optimal foldover plan? How do we use optimal foldover plans to construct combined designs which have better capability of estimating lower order effects? The main objective of the present paper is to provide answers to these questions. Using the new results in this paper as benchmarks, we can implement a powerful and efficient algorithm for finding optimal foldover plans which can be used to break links between aliased effects.     

社会安全阀运行与和谐社会构建

社会安全阀具有宣泄社会情感、激发制度创新与整合社会结构的重要功能。由于制度化手段的缺失,当代中国社会安全阀机制具有潜制度化特征并在运行中逐渐显现出弊端,已不能适应社会和谐发展的需要。应该引入制度化的手段,用“显社会安全阀”替代“潜社会安全阀”,在经济、法律、政治、社会生活诸领域中实现社会安全阀的制度化运行机制。
