[目的/意义] 针对现有社交媒体倦怠影响因素的探究中存在不一致和差异性的问题,使用定量分析方法对已发表的实证研究文献中的统计结果进行梳理总结和再统计。[方法/过程] 本研究从68篇实证研究文献中共提取出72组224个效应值进行研究,将社交媒体倦怠影响因素归纳为情境和本体两大因素,并提炼出平台类型、文化特征、社交媒体使用程度、用户性别及被试群体5个调节变量。使用元分析定量分析方法,通过异质性检验和次群体检验来探讨不同因素对社交媒体倦怠的影响,并检验调节变量对社交媒体倦怠影响的显著性。[结果/结论] 研究结果表明,情境因素和本体因素均对社交媒体倦怠产生显著的正向影响;两者对社交媒体心理倦怠的影响均强于对社交媒体行为倦怠,而情境因素与社交媒体倦怠之间呈现出更高的相关性。同时,本研究归纳识别的5类调节因素在本体因素与社交媒体倦怠之间具有一定的调节效应,而情境因素与社交媒体倦怠之间的关系仅受到被试群体的调节。  相似文献

ABSTRACT

Social media is a powerful tool for building an online presence, but it asks a lot. While it affords plentiful opportunities for professional development and networking, building a professional brand in an online space is not without its drawbacks and risks. By working from a set of actionable principles and benchmarks, users can minimize frustrations and setbacks to build a useful professional presence, all while imbuing the web with the tenets of good information stewardship.  相似文献

The independence of the media under Ghana’s Fourth Republic is assessed from the perspective of standards and professionalism. Using a qualitative method, the study shows that unethical practices are evident in the print media landscape in Ghana, and argues that this can be traced to four major spheres: educational qualification, existence of several professional associations, a weak regulatory body and “money matters”. Overall, the study argues that legalities form a minimal part of the independence of the Ghanaian media but concerns about freedom seem to be self-inflicted by the very media practitioners through their actions and sometimes questionable reportage.  相似文献

Around 1960, the politics of the emerging media society in Sweden tended to fixate the formative functions of mass communication. The monopoly of public service broadcast media, press subsidies and new tendencies in film policy were some of the issues around which uncertainty prevailed. New methods to provide reliable data were sought by politicians, since empirical facts were required as arguments for an updated media policy. This article examines the different ways that the field of media studies was introduced in Sweden between 1960 and 1980. We argue that Swedish academic media studies departed from, and emerged within, a rather diffuse borderland between industry, politics and academia. The formation of national media research in Sweden can partly be seen as an effect of politicians and the media industry wanting to be better informed on issues such as media influence, media ownership and the habits and composition of the media audience.  相似文献

If democracy is a platform for many voices, and the voices of the many, journalists serve democracy by bringing these voices to the forefront of governance by asking difficult questions to those in power. It can be argued that journalists engage in the broader form of surveillance of power from below, or sousveillance [Mann, Steve, and Joseph Ferenbok. 2013. “New media and the power politics of sousveillance in a surveillance-dominated world.” Surveillance and Society 11 (1-2): 18–34.], which aims towards a form of relative equilibrium. In democracies, the institutional system of checks and balances forms the basis on which journalism pursues its watchdog function. This paper explores the experiences of journalists with surveillance and their impact on journalists’ sense of freedom to fulfil their watchdog role. The paper contributes to increasing research interest in “journalism after Snowden” by addressing the intangible conditions under which journalists may or should work, and ultimately also how widely accepted standards of democratic liberties are challenged.  相似文献

This research examines privacy law and Human Flesh Search (HFS) on the Chinese Internet. HFS is spontaneous, widely participated search and publication of targeted individuals’ personal information on the Internet. This research sees HFS as an important form of non-institutional information gathering and publication, and argues that the regulation of HFS is not only about privacy but also line-drawing for information collection and dissemination in the digital setting. Therefore, legal instruments and court cases in relation to HFS and online privacy must be assessed as important components of the Chinese state’s Internet regulatory scheme. This research finds that the paired concepts of ‘flexibility and populism,’ key features of legal reform and development in contemporary China, are highly relevant to analyze the growth of digital privacy laws in China. The political-legal authorities’ experimentation and innovation in the development of the law shed important light on how China’s Internet governance adapts to changing circumstances and strives to keep pace with profound social transformations in new technological environments.  相似文献

This paper outlines a history of the union organizing of the American Newspaper Guild at Thomson Newspapers’ Peterborough Examiner in Canada from 1968 to 1969. It examines the communication tools that union members used to facilitate this labor organizing and “bite back” at the profitable Thomson chain. Peterborough newsworkers went on strike from November 1968 to April 1969 over union recognition. During the strike, the union members built an unprecedented alliance with Ontario university students, collaboratively launching a strike newspaper called the Peterborough Free Press. Expanding on the concept of temporary labor convergence, this paper considers how strike newspapers can be seen as a form of alternative journalism that newsworkers use as a campaigning tool to communicate their struggles to the public and put pressure on news corporations to bargain with them. This case study is situated in the local institutional contexts of labor relations at the Peterborough Examiner and the news industry in Peterborough, where Thomson Newspapers had a media monopoly. It is based on labor standpoint and signal juncture analyses of union archival documents and newspaper content. The research ultimately suggests that newsworkers should not only focus on communication tools but also build bridges with community members.  相似文献

Given the iconic status assigned to Gallipoli, virtually from the outset, it was inevitable that in its centenary year, commemoration would receive enormous political and media attention. My intention is not to produce a comprehensive summary of all international media output on Gallipoli, even if that were possible within the confines of a journal article. Language barriers and problems of access have further impacted on the selection process, as well as in the coverage of even countries that have been examined (I do not speak French, German or Turkish; I also did not have access to non-English publications in India.). Nor is the article meant to be a synthesis of historiographical debate on Gallipoli, a subject which military and other experts have successfully addressed in the past as well as during the centenary (Please see reference section below for a selection of relevant books.). Rather, my more modest aim is to highlight seminal themes and offer an assessment of response, both in and by the media, especially the print media, in some of the main belligerent countries situated today in differing geo-political contexts, viz. Great Britain, Australia, India (then part of the British empire) and Turkey (then part of the Ottoman empire). Arguably, at one level, there was little in the transnational response during 2015 which attempted to shift the foundational basis for a reading of Gallipoli that has been established in the media during the intervening decades. Yet, there were some notable shifts in transnational perspectives. Perhaps after the lapse of a century, it may be possible to achieve/restore some kind of balance to our appraisal of Gallipoli in the public mind.  相似文献
