Social networks are one of the most used communication methods of today's world. Their use in different fields has been examined in several research studies. This study aims to examine the effects of social media on student's behaviors which will mainly focus on Facebook. Whether there is a positive relationship between confidence, social media participation and social media related behaviors will also be assed with regard to using Facebook. In order to collect the primary data, a general scanning model was used to observe attitudes of high school students. The participants chosen were 362 high school students from level 9 to 12. The findings highlight that Facebook is used for communication entertainment and sharing news, pictures and songs. In addition, their Facebook profile picture is alone and students were aware that swearing is considered a form of misconduct, which is a good sign. The study also indicates that students were aware of protecting their social identity as their Facebook shares are not public. Furthermore, they respect privacy as they do not use their friend's Facebook account.  相似文献

This study develops a research model that explains the continuance of corporate social network service (SNS) pages. In order to find antecedents that influence end users’ continuance intention, this study adopts communicative ecology theory from media and communication studies. Results indicate that the quality of social interaction is the most salient feature, as indicated by the fact that it has the highest impact on perceived usefulness and enjoyment. Moreover, content quality also increases both perceived usefulness and enjoyment, while SNS platform quality and service quality increase perceived usefulness only. In addition, perceived network size moderates the impact of social interaction quality on perceived enjoyment.  相似文献

This study proposes and empirically examines a research model that incorporates the knowledge creation mode and social networking mode to describe knowledge creation performance. The mediation effect of the knowledge creation process is explored in terms of socialization, externalization, combination, and internalization (SECI). The data collected from the manufacturing and service industries in Taiwan were analyzed. The goal-driven mode and web topology are found to be significantly associated with product or service creation primarily because of the creation efficacy aspect. The SECI with web topology has a mediation function when the goal-driven mode is adopted. Implications and suggestions are also provided.  相似文献

Based upon the stressor-strain-outcome framework, this study proposes that perceived system feature overload, information overload, and social overload are stressors which induce strain, in terms of social network fatigue and dissatisfaction. Both of social network fatigue and dissatisfaction further influence discontinuous use intention. The empirical results indicate that three types of perceived overload exert greater effects on social network fatigue than dissatisfaction, both of which further increase users’ intention of discontinuance. The study also finds that demographic characteristics, such as gender and age, also have moderating effects on these relationships.  相似文献

A well-designed field trip can promote active learning and reinforce classroom materials. Few studies have examined the potential for social media to enhance IS field trip experiences by promoting active and collaborative learning. One major barrier to the exploitation of this potential is the lack of the adoption of social media by students as a learning tool to enhance field trip experiences. Therefore, the first task is to understand how to increase the satisfaction of students in their use of social media to enhance IS field trips. This research sets out to understand the factors that could help increase students’ satisfaction with the use of social media to enhance IS field trips, and thereby their intentions to continue to use social media in future field trips. The results show that to increase user satisfaction, course instructors should ensure that students perceive the social media sites used for enhancing field trip study to be trustworthy, effortless, useful and accepted by their peers. Future research could determine how we can incorporate the use of social media to enhance the field trip learning experience.  相似文献

Political information sharing in social media offers citizens opportunities to engage with news and express their political views, but how do different patterns of online political information exposure, including both incidental and selective exposure, affect sharing? Using two‐wave panel survey data collected in the United States, we examine the relationship between incidental and selective exposure and their consequent links to political information sharing, across different levels of strength of political party affiliation. Our results demonstrate that incidental exposure to counter‐attitudinal information drives stronger partisans to more actively seek out like‐minded political content, which subsequently encourages political information sharing on social media. The results highlight the need to consider both types of political information exposure when modeling citizens' political behavior online.  相似文献

ABSTRACT

Scholars and activists have studied social movement media for its potential to challenge dominant narratives, build community relationships and create social change. This paper presents a case study of two short-form documentary projects with Black Lives Matter 5280 and the Service Employees International Union, Local 105 in Denver, Colorado to explore how collaborative media-making projects assist in building local grassroots campaigns of racial and economic justice. The communication strategies as well as the distribution efforts via online social networks and community screenings are discussed in order to analyse how documentaries rely upon personal narratives to animate members and allies’ feelings and then connect them with traditional forms of organizing like community meetings and public demonstrations. The participatory aspects of filmmaking are viewed through democratic theory, which emphasizes the social relations of citizenship and shared communal values over material and cultural resources, rather than visual aesthetics or technical processes.  相似文献

ABSTRACT

This article serves as an introduction to a special issue of the journal Digital Creativity, which addresses the challenges, potentials and meaning of different creative forms of citizenship enacted through social media. The articles in this special issue paint a complex picture of the expressions and meaning and citizenship. This introduction aims to provide a wider context for the contributions to this special issue by reviewing some of the claims made for the creative civic potential of social media and identifying a number of issues and questions that might inform analyses of the subject.  相似文献

随着社交网络的流行,从各种各样的社交网络数据中提取出有效信息并进行清晰直观的可视化分析,从而为用户提供有价值的潜在知识,显得尤为重要。聚类分析是数据挖掘中的重要分析手段,传统的面向社交网络数据的用户聚类分析大都仅考虑网络的拓扑链接结构,未考虑用户的兴趣相似度。文中基于贝叶斯概率模型来计算用户兴趣相似度并进行聚类,进一步设计交互可视化方式来展示上述聚类结果。具体地,针对社交网络中的用户评分数据 建立潜在语义模型来提取表示每个用户兴趣特点的特征向量;基于用户的特征向量对用户进行聚类,得到具有不同特征的人群,并通过实验和热度图选择合适的人群聚类数;最后提出了基于层次气泡图的可视化展现和分析方案,将用户、电影类型、电影等多维信息在图形中交互展示,支持用户从全局概览到局部细节的推进式探索,从多角度可视化人群特征。对豆瓣网用户和电影评分数据进行了实验和分析,结果验证了所提方法的有效性。  相似文献
