How social media matter: Repression and the diffusion of the Occupy Wall Street movement

This study explores the role played by social media in reshaping the repression-mobilization relationship. Drawing on the case of the Occupy Wall Street movement, we examine the impact of Facebook and Twitter on the spatial diffusion of protests during a period of heightened state repression. Results from event history analyses suggest that the effects of repression on protest diffusion are contingent on the presence of social media accounts supporting the movement. We find that state repression at earlier protest sites encouraged activists to create Facebook and Twitter accounts in their own cities, which then served as important vehicles for the initiation of new Occupy protests. Moreover, results suggest that repression incidents can directly facilitate future protests in cities that already have Occupy Facebook accounts. This study highlights the potential of social media to both mediate and moderate the influence of repression on the diffusion of contemporary movements.     

Parameter estimation for multivariate diffusion processes with the time inhomogeneously positive semidefinite diffusion matrix

Statistical inference for the diffusion coefficients of multivariate diffusion processes has been well established in recent years; however, it is not the case for the drift coefficients. Furthermore, most existing estimation methods for the drift coefficients are proposed under the assumption that the diffusion matrix is positive definite and time homogeneous. In this article, we put forward two estimation approaches for estimating the drift coefficients of the multivariate diffusion models with the time inhomogeneously positive semidefinite diffusion matrix. They are maximum likelihood estimation methods based on both the martingale representation theorem and conditional characteristic functions and the generalized method of moments based on conditional characteristic functions, respectively. Consistency and asymptotic normality of the generalized method of moments estimation are also proved in this article. Simulation results demonstrate that these methods work well.

Adolescents,Online Marketing and Privacy: Predicting Adolescents’ Willingness to Disclose Personal Information for Marketing Purposes

The present study aims at exploring which factors predict the willingness of adolescents to disclose personal information in response to online marketing requests. Our analyses show that especially privacy concerns and perceived benefits explain a considerable portion of variance in both willingness to disclose profile data (e.g. age, hobbies, favourite products) and contact data (e.g. phone number, e‐mail address, home address). An interesting interrelationship was found between profile data and contact data disclosure. Contrary to our expectations, parental mediation strategies were only a weak predictor of teenagers’ willingness to disclose contact information. Policy implications that emerge from the central findings of this study are discussed.     

“互联网+”助推民营经济发展路径探析

在“互联网+”时代,新技术迅速发展,各种信息变得更为透明,民营经济若想充分利用现有资源,探索出适合企业的发展路径,就必须充分利用好互联网平台,将互联网与企业深度融合,充分发挥“互联网+”中“+”的作用。但是由于在利用互联网探索发展路径的过程中,存在领导层网络意识淡薄、难以改变旧有的商业模式、构建网络平台能力差、与合作企业之间存在信任短板等方面的问题,导致在平台利用上缺少一定的条件。在这种情况下,民营企业要充分认识“互联网+”,并且抓住机遇,融入“互联网+”的大潮中,树立互联网思维模式,努力构建网络信息中心平台,提升民营企业互联网接入水平,政府也应搭建相应的网络平台促进民营经济转型升级。     

网络语言暴力法律规制的必要性和立法构想

网络语言暴力的泛滥以其独有的方式撕裂了道德底线,向现行法律制度提出了挑战。此类事件不能仅在道德层面进行约束和思考,道德的谴责已无济于事,必须从法律层面进行约束和思考。网络语言暴力属于名誉侵权行为。既然属于侵权行为,那就应当纳入法律调整的范围,以法律从主体、客体、内容和责任方面进行有效规制。这样有利于拓宽法治的空间、更好地保护当事人的合法权益,惩治、震慑和预防网络语言暴力侵权行为,净化网络社会环境。
