Over the past decade, social media have become an increasingly important component in the ways broadcasters communicate with their audiences. A relative newcomer to that mix is the social network Pinterest, which enables followers to post photos and other types of visuals based on topics of interest. A content analysis examined how 85 local television stations are using that social network for promotion and branding. Results showed that, rather than promotion, use of Pinterest primarily revolves around lifestyle content, including postings by stations and interactivity by followers.  相似文献

The author investigates how social media affects stock prices and post–earnings announcement drift in response to companies’ quarterly earnings announcements. Using quarterly earnings data as well Twitter and StockTwits data, the author utilizes Twitter volume and a residual methodology to generate an attention proxy that is orthogonal to the growth of Twitter accounts. The author finds that the new attention brought by social media after the earnings announcements positively affects the cumulative abnormal returns. Further, even companies reporting bad news can still have positive immediate cumulative abnormal returns if they attract enough attention from investors after an earnings announcement. The new attention effects are different in both magnitudes and statistical significance between social media popular and unpopular industries.  相似文献

ABSTRACT

The co-option of consumers as unwilling agents in their own surveillance has enabled significant abuses of consumer privacy. Previous studies have largely used privacy concern as a proxy for overall privacy attitudes. In this study, we implement a choice experiment in combination with measures adapted from Communication Privacy Management theory to enable a broader exploration of the influences of privacy attitudes by contextualising privacy as a negotiation about accessibility over contextual boundaries. Key findings suggest individuals’ social media disclosure decisions are influenced at least in part by their privacy attitudes, particularly with respect to information categories which may cue other personal information. Findings are also presented on consumers’ willingness to pay for privacy, with implications for alternative revenue streams not built on consumer surveillance.  相似文献

电子媒介的兴起使传统的文学步入边缘化的境地——远离艺术中心,沦为最低级的科学。从文学媒体介质的变化、阅读主体与接受主体、后现代的审美取向等角度观察现代传媒对文学的影响:改变因垄断话语权而使少数精英滋生不可一世的贵族心态的传统文学观念,使其由崇高、严肃、宏大、华丽典雅的审美趣味向朴素、通俗的大众化和世俗化倾斜。  相似文献

ABSTRACT

While traditional anti-tobacco social marketing campaigns have focused on prevention and cessation, a new breed of anti-tobacco message has arisen during the last decade, which focuses on attacking the tobacco industry and its tactics. This type of anti-tobacco program has been termed a tobacco industry manipulation campaign in the United States, where it was introduced in the early 1990s. The objective of a tobacco industry manipulation campaign is to point out negative traits of the tobacco industry, including manipulative marketing strategies and tactics. Evaluations of tobacco industry manipulation campaigns have found that these ads are effective in redirecting the guilt that smokers often feel, channeling it instead into anger at being manipulated. Guidelines are provided for how social marketers can incorporate this approach within their tobacco control campaigns.  相似文献

This study examines the determinants of Facebook activity levels with a particular focus on Facebook activity around earnings announcements. Facebook activity is generally higher for firms with higher levels of analyst following, individual ownership, and trading volume, indicating that it is responsive to investor demand effects. Facebook activity also increases around earnings announcements, with the increase being largely attributable to posts containing earnings news. In general, therefore, firms use Facebook posts to amplify earnings news. Such activity is selective, however; it is lower for firms with high levels of information asymmetry, for firms reporting earnings that exactly meet the consensus analyst forecast amount, and when the earnings news is negative but the accompanying price movement is positive. Hence, firms appear to use Facebook to manage the level of attention paid to earnings news.  相似文献
