《非诚勿扰》节目失范行为的传媒环境学解读

传媒环境学派一直将传播媒介视为考量传播效果的关键性因素。将《非诚勿扰》节目中出现的“作秀”、“缺乏真实性”和“言语粗俗”等问题置于传媒环境学视域下进行考察,能发现该节目出现失范行为的本质原因在于电视媒介本身,而非其他。     

西方广告商与媒体的关系对中国媒体的启示

西方广告商对媒体施加了直接和间接的压力,其后果是媒体公信力的丧失和报道的同质化。在我国,广告商对媒体的控制虽未达到西方的水平,但却呈现愈演愈烈的趋势。因此政府和媒体要及时采取措施,防微杜渐。     

Resistance as method: unhappiness,group feeling,and the limits of participation in a digital storytelling workshop

This paper offers a narrative case study of Mirabel, one participant in a digital storytelling workshop for women who were newcomers to Canada, whose experience compelled me to rethink conceptualizations of participation in social justice-oriented, community-based participatory media projects. Drawing on the work of Sara Ahmed, I consider how Mirabel’s resistance to the ‘promise of happiness’ offered by the group was interpreted by others as a failure to participate. Conversely, I suggest that Mirabel’s experience and her digital story are generative for thinking about resistance as a method of participation and a political resource for the group. I argue that conceptualizations of participation should be complicated to include the kinds of agency demonstrated by participants like Mirabel who resist the norms of the digital storytelling workshop and group culture.     

论高校思想政治教育载体的整合运用

课程载体、活动载体、管理载体、校园文化载体、网络载体等是高校思想政治教育的主要载体,这些载体的运用是一项复杂的系统工程,要实现这一系统的最佳运行和综合优化,就必须进行思想政治教育载体的整合运用。这种整合运用主要涉及到高校思想政治教育载体发挥作用的目标相协调、各载体承载的教育内容相协调、各载体发挥功能相协调、各载体运作方式相协调。     

国家重点实验室网络影响力评价及实证研究

为衡量国家重点实验室在新时代背景下的网络媒体影响力,构建网络媒体影响力评价体系,以此分析国家重点实验室的网络媒体影响力水平。利用层次分析法构建国家重点实验室网络媒体影响力评价指标体系,并计算相应的权重系数,同时选取156所国家重点实验室进行实证研究。研究显示,国家重点实验室间的网络媒体影响力参差不齐,且大多数与第三方平台影响力水平同步;国家重点实验室在自主平台特别是微信和官网的利用上还有很大的提升空间。并据此建议积极与多类社交媒体建立联系、强化微信公众号的内容建设以及加强对官方网站的建设与维护等建议。     

Determinants of public engagement on municipal Facebook pages

Abstract

This article analyzes the determinants of public engagement on the Facebook pages of municipalities. The sample consists of 170 Italian and Spanish municipalities that used Facebook in 2014. The findings show that posting a lot of information on municipal Facebook pages does not increase the engagement of citizens. Also, frequent posting of information per se does not engage public engagement. However, if the posts are published when public can pay attention to them (e.g., off days), the likelihood of public engagement increases. Furthermore, the citizens’ engagement on municipal Facebook page depends on the level of citizens’ income – there is a negative relationship between citizens’ income and the level of participation.     

Social media opinion summarization using emotion cognition and convolutional neural networks

Quickly and accurately summarizing representative opinions is a key step for assessing microblog sentiments. The Ortony-Clore-Collins (OCC) model of emotion can offer a rule-based emotion export mechanism. In this paper, we propose an OCC model and a Convolutional Neural Network (CNN) based opinion summarization method for Chinese microblogging systems. We test the proposed method using real world microblog data. We then compare the accuracy of manual sentiment annotation to the accuracy using our OCC-based sentiment classification rule library. Experimental results from analyzing three real-world microblog datasets demonstrate the efficacy of our proposed method. Our study highlights the potential of combining emotion cognition with deep learning in sentiment analysis of social media data.     

Social media and entrepreneurship research: A literature review

The rise of social media has led to changes in how entrepreneurs carry out their day-to-day activities. Studies on social media and entrepreneurship are relatively new and fragmented in their focus, however there is increasing interest from academia and practitioners for further research and investigation within this area. This study systematically reviews research carried out in the domain of social media and entrepreneurship. A total of 160 papers, published between 2002 and 2018 were synthesised to identify critical theories and research methods used in the domain. Based on the extent review, an integrative framework was developed to identify relationships amongst elucidated constructs. While most papers investigated the factors that drive social media adoption and use by entrepreneurs, it was found that the use of social media by entrepreneurs had transcended marketing and it is now used in business networking, information search and crowdfunding for their business. This has led to significant impact with improved firm performance and innovation enhancement being the essential outcomes. The literature review and framework further understanding of social media and entrepreneurship research, providing a useful basis for future studies and informs practice in this area.     

The role of social media in the engagement and information processes of social CRM

This study furthers investigation into exactly how Social CRM (S-CRM) is different from traditional CRM, and models the interrelationships between its capabilities. It is underpinned in dynamic capabilities theory, to explain how social media, as a resource all organizations use, can lead to differing performance outcomes. It is underpinned in seminal research into traditional CRM, but which does not cater for the disruptive nature of social media. We outline how S-CRM is a second-order dynamic capability consistng of a set of first-order integrative dynamic capabiliies that, when properly interrelated, lead to performance outcomes. We particularly model the role of S-CRM front- and back-office technology capabilities, customer engagement initiatives, and social information processes in driving customer relationship performance. Findings show that S-CRM is different from traditional CRM in a range of ways in the front- and back-offices, and provide a framework for researcher and managers in information systems and marketing to operate at strategic and tactical levels within S-CRM, while being congisant of both.
