Spectacles of intimacy? Mapping the moral landscape of teenage social media

This paper explores young people's expressed concerns about privacy in the context of a highly mediated cultural environment, mapping social media practices against axes of visibility and participation. Drawing on interdisciplinary conceptual resources from both the humanities and social sciences, we use ‘spectacles of intimacy’ to conceptualise breaches of privacy, mapping an emergent moral landscape for young people that moves beyond concerns with e-safety to engage with the production and circulation of audiences and value. The paper draws on data from a methodological innovation project using multi-media and mixed methods to capture lived temporalities for children and young people. We present a model that captures a moral landscape shaped by emotional concerns about social media, the affordances of those media and affective discourses emerging from young people's use of the media.     

People with disability and new disaster communications: access and the social media mash-up

This article explores how a lack of access to increasingly complex and overlapping digital communications platforms in times of disaster for people with disabilities has the potential to make already life-threatening situations considerably more dangerous. As we are increasingly coming to rely on a social media mash-up of digital platforms to assist in communications during disaster situations, the issue of accessibility for people with disabilities is as dire as if it was high ground during a tsunami or transport during a typhoon. The contemporary social media environment is characterised by a complex and overlapping network of complementary platforms, populated by user-generated content, where people communicate and exchange ideas. In this environment, YouTube videos are posted to Facebook and embedded in blogs, and Twitter is used to link to these other sites and is itself embedded in other platforms. These networks are increasingly supplementing and supplanting more traditional communication platforms, such as the television and radio, particularly in times of disaster. The concern of this paper is that the elements from which this mash-up of communications channels is made are not always accessible to people with disabilities. This evolving network of social media-based communication exposes the limits of existing Internet-based universal design.     

孔隙介质中滞留聚合物分子的粘弹效应系数

本文在文献[1]的基础上做了进一步的试验研究,发现慢速降压过程流速对时间的依赖关系呈指数曲线形式,同时进行了慢速升压试验,同样发现流速与时间的指数关系。文中对文献[1]定义的附加残余效应系数提出了修改,重新定义为滞留分子粘弹效应系数,对降压过程和升压过程的粘弹效应系数进行了对比。通过岩心出口液浓度数据,证实了文中描述的粘弹效应机理和分子构象改变的物理模型的可靠性。     

Young people,social media and connective action: from organisational maintenance to everyday political talk

Social media is pervasive in the lives of young people, and this paper critically analyses how politically engaged young people integrate social media use into their existing organisations and political communications. This qualitative research project studied how young people from a broad range of existing political and civic groups use social media for sharing information, mobilisation and, increasingly, as a means to redefine political action and political spaces. Twelve in-person focus groups were conducted in Australia, the USA and the UK with matched affinity groups based on university campuses. The groups were of four types: party political group, issue-based group, identity-based group and social group. Our focus group findings suggest that this in-depth approach to understanding young people's political engagement reveals important group-based differences emerging in young people's citizenship norms: between the dutiful allegiance to formal politics and a more personalised, self-actualising preference for online, discursive forms of political engagement and organising. The ways in which political information is broadcast, shared and talked about on social media by engaged young people demonstrate the importance of communicative forms of action for the future of political engagement and connective action.     

What is Flint? Place,storytelling, and social media narrative reclamation during the Flint water crisis

ABSTRACT

The Flint Water Crisis became a national news story in January of 2016, when major publishers such as The New York Times began covering the story. In the same month, an influx of social media activism occurred in response to the crisis, with citizens developing hashtag campaigns such as #FlintFwd in order to disseminate news and stories from a citizen’s perspective; these campaigns often positioned Flint positively ? as a recovering community ? rather than a city in the middle of a public health crisis, and often addressed not a national public but a local audience. This paper considers Flint-based social media activity to investigate the emergence of place-based activism within the ostensibly global network of social media. In doing so, it identifies three key themes; 1) leveraging social media to forward a critique of deficient journalistic storytelling; 2) using the affective process of storytelling via social media to claim authority over their own material offline existence, and 3) using place-based storytelling to implicate others as witnesses via the global network of social media. These themes coalesce around a distinctly critical logic of connectivity. This logic extends the notion of connectivity articulated by Van Dijck and Poell [2013. Understanding social media logic. Media and Communication, 1(1), 2–14.] and the strategies of platform activism explored by Tufekci [2017. Twitter and tear gas: The power and fragility of networked protest. New Haven: Yale University Press.] to explain how social media works to expose discrepancies between the public story of the water crisis and material, lived conditions of Flint, rendering visible a discursive identity of Flint thus far unrecognized.     

大众传播中的“国家教师”媒介形象分析

运用传播学内容分析法，以中央媒体对获得"全国教书育人楷模"和"最美教师"荣誉称号的"国家教师"相关报道为研究对象，从外在和内在两个方面对大众传播的"国家教师"媒介形象进行分析。外在形象包括教师性别、年龄、教龄、外表、场景以及任教的学校类别、区域、学科专业等方面，内在形象包括职业精神、职业知识和职业能力等方面。研究发现，大众媒体对"国家教师"形象的刻画和宣传符合社会公众认知教师职业的基本逻辑，起到了传递教师精神、端正教师形象、唤起社会尊重教师的功效，但也存在城乡教师形象传播刻板化以及教师普通人形象展现不充分等问题，可在后续的传播中对"国家教师"形象的价值倾向进行适当调整。     

消费者网评使用习惯对网评效应的影响研究---网评奖励效果的中介和调节效应探索*

本文以网购旅游者为调查对象，分析其网评使用习惯及其在网评奖励效果作用下对网络评论效用发挥的影响。通过问卷调查和数据分析发现，网评使用习惯和网评奖励效果都对网评效应具有显著正向影响，但网评使用习惯的影响力大于网评奖励效果。同时，网评奖励效果对网评使用习惯与网评效应间的关系具有显著负向调节效应，它削弱了消费者网评使用习惯对网评效应的影响；但消费者的网评使用习惯不通过网站的网评奖励效果对网评效应发挥作用，网评奖励效果不具有中介作用。可见，在网评使用习惯、网评奖励效果和网评效应三者关系中，网评使用习惯是个独立的影响因素，它并不通过网评奖励效果发挥作用，并且由于网评奖励效果的加入，反而削弱了网评使用习惯对网评效应的影响。研究结论表明，对于网评奖励政策的效果，需要客观辩证地看待，不应一味夸大。

网上的西欧政党

20世纪90年代以后，互联网在全球迅速普及，对西欧政党产生了重要的影响。为适应自身发展的需要，获得更多选民的支持，西欧各国政党纷纷上网。他们竞相在网上开展各项活动。主要包括提供信息、网上竞选、政治参与和组织建设，并取得了一定的成效。但是，受到数字鸿沟、政党实力、政党利益、党员和选民态度的影响，西欧政党的网上潜能没有得到充分地发挥，政党的网上效力有待于进一步提高。
