The authenticity of social-media performance: lonelygirl15 and the amateur brand of Young-Girlhood

This article analyzes the gendered expectations of authenticity in online amateur media performances through a reading of the 2006 vlog series lonelygirl15. Actress Jessica Rose was part of an artistic collective that created the character of Bree, a teenage girl who posted a series of confessional vlogs on YouTube under the screen name lonelygirl15. The vlog quickly went viral due, in part, to the almost immediate suspicion that the series was “fake.” Through a close reading of both the coverage of the sting that revealed Bree's true identity, and the narrative of the series itself, the author illustrates how the series aestheticizes precarity in order to facilitate escalating modes of intimacy with Bree's character. By placing such demands within the longer history of girls’ media production, such as the video work of Sadie Benning and Camgirl websites, this article argues that the reaction to the series makes visible the increasing political significance of the entanglement of economic concerns and identity production within the networked social sphere.     

论优化高校思想政治教育新媒体平台的路径——基于大学生新媒体使用倾向性的调查

新媒体以其信息的即时性和丰富性等特点,成为了大学生获取信息和人际交往的重要渠道。在新媒体平台的使用过程中,大学生更青睐于使用新兴媒体,更愿意从新媒体平台中获取实用性强的信息,更注重新媒体的交互性。高校思想政治教育新媒体平台应该以大学生的新媒体使用习惯为依据,从打造新媒体集群,发布更关注大学生诉求的信息内容,设计形式多样的新媒体活动,优化新媒体平台建设,加强与大学生互动等方面着手,加强新媒体平台的建设。     

War of words: the impact of Russian state television on the Russian Internet

How effective is Russian state television in framing the conflict in Ukraine that began with the Euromaidan protests and what is its impact on Russian Internet users? We carried out a content analysis of Dmitrii Kiselev's “News of the Week” show, which allowed us to identify the two key frames he used to explain the conflict – World War II-era fascism and anti-Americanism. Since Kiselev often reduces these frames to buzzwords, we were able to track the impact of these words on Internet users by examining search query histories on Yandex and Google and by developing quantitative data to complement our qualitative analysis. Our findings show that much of what state media produces is not effective, but that the “fascist” and anti-American frames have had lasting impacts on Russian Internet users. We argue that it does not make sense to speak of competition between a “television party” and an “Internet party” in Russia since state television has a strong impact in setting the agenda for the Internet and society as a whole. Ultimately, the relationship between television and the Internet in Russia is a continual loop, with each affecting the other.     

Troubling the ontological bubble: middle school students challenging gender stereotypes

In this paper, we discuss how a selection of eighth-grade students (13–14-year-olds) responded when they were asked to publicly challenge the gender binary for a critical media literacy school assignment in the USA. We describe the ways in which students negotiated the dual projects of complying with the assignment to create video ads that challenged gender stereotypes and maintaining their gendered sense of self. While the videos had virtually all students disrupting gender in some way, many did so even as they reinforced the notion of gender as a binary. We apply the idea of ontological bubble, as well as concepts from post-structural theories, to help us make sense of the different methods students used to maintain the gender binary.     

Doing good or doing nothing? Celebrity,media and philanthropy in China

Based on a statistical analysis of 91 celebrity-endorsed charities in the People’s Republic of China, this paper challenges the popular assumption that celebrity involvement with not-for-profit organisations attracts extensive media coverage. Although China is the largest media market in the world, previous studies of celebrity philanthropy have been conducted almost exclusively in a Western context. Such studies argue passionately for and against the role that celebrities can play in attracting attention to humanitarian causes, focusing on the activities of Western celebrities, corporations and consumers as essential or problematic promoters and providers of aid to people in developing countries. We show that – in China, at least – most of this debate is overblown. Rather than arguing in favour of or against celebrity philanthropy, we provide statistical results suggesting that celebrity endorsement has very little impact on press coverage of charities.

警风构成论

了解警风的构成要素对于认识警风及其发展具有重要意义。警风是由警察认识、警察价值观、警察行为方式诸要素构成的一个有机整体。警察认识是多样化的、多层次的,既有日常感知层面的认识,也有抽象理论层面的认识,它是警风的依存基础。警察价值观是警察组织生存的基点和灵魂,是警察善恶是非判断的标准,是警察群体对所认同的目标持续一贯的追求,主导着警察制度的性质和方向,决定着警察的行为方式,它是警风的内在灵魂,在深层次上制约着警风的形成与发展。警察行为方式是警风的外显机制,是警察认识和警察价值观的外化,它包括交流、合作和冲突等。     

Exploring the Paradox of Liberal Democracy: More Political Communications Equals Less Public Trust

Francis Fukuyama asks: ‘Is liberal democracy prey to serious internal contradictions, contradictions so serious that they will eventually undermine it as a political system?’ This paper argues that one of these ‘internal contradictions’ is the political communications process and it can be sufficiently serious to undermine the democratic system—but such an undermining is not inevitable.     

四物汤对血管性痴呆大鼠的神经保护作用及其机制研究

目的 探讨四物汤对血管性痴呆（vascular dementia,VD）大鼠的保护作用及其机制。方法 将SD大鼠随机分为假手术组,模型组,四物汤高剂量（6 g/kg）、低剂量（3 g/kg）组,尼莫地平组（20 mg/kg）,每组12只。采用大脑中动脉阻塞再灌注法复制大鼠VD模型,术后连续给予相应药物14 d。采用水迷宫实验观察VD大鼠学习能力和记忆能力;酶联免疫吸附法测定海马组织中乙酰胆碱酯酶（acetylcholinesterase,AChE）、5- 羟色胺（5- hydroxy tryptamine,5- HT）、内皮素- 1（endothelin- 1,ET- 1）、血管内皮生长因子（vascular endothelial growth factor,VEGF）的含量。腹主动脉取血检测血液流变学指标。苏木精- 伊红染色观察海马CA1区神经细胞形态学变化。结果 与模型组比较,四物汤高剂量组大鼠逃避潜伏期明显缩短（P<0.05）,在目标象限距离百分比显著增加（P<0.05）,海马AChE、ET- 1含量显著降低（P<0.05）,5- HT、VEGF含量显著升高（P<0.05）,全血黏度、血浆黏度和红细胞聚集指数显著降低（P<0.05）。四物汤高、低剂量组比较,仅血浆黏度和红细胞聚集指数的差异具有统计学意义（P<0.05）。与模型组比较,四物汤组海马CA1区锥体细胞缺失减轻,神经纤维排列整齐,仅少数细胞核固缩。结论 四物汤对VD具有一定的改善作用,其机制与改善神经递质,调节海马ET- 1、VEGF含量,改善血流状态有关。
