Social media have become an integral part of online news use, affecting how individuals find, consume, and share news. By applying the Theory of Reasoned Action (TRA), this study investigates the effects of motives, attitude, and intention on news-sharing behavior among German social media users (n = 333). Findings show that news-sharing attitude and subjective norms have a positive effect on news-sharing intention, which in turn has a positive effect on actual news-sharing behavior. Taken together, we see that a new media behavior in the early phases of its societal diffusion—like social media news sharing in Germany in 2015—can mainly be explained by a rational choice logic and is rooted in the motives of socializing and information seeking. This finding thus reflects the double nature of social media as a means for both information retrieval and social grooming.  相似文献

Binge-watching—the intensive, consecutive viewing of televised series—has become a prevalent usage pattern of entertainment media, which may influence users’ psychological well-being both positively and negatively: On the one hand, binge-watching could increase viewers’ enjoyment, recovery experiences, and vitality through an increase in perceived autonomy. On the other hand, binge-watching can trigger goal conflicts and feelings of guilt, which may reduce well-being. Drawing on an online survey (N = 499), the present study examines the tension between these two mechanisms and their effects on users’ well-being. The data largely support the hypotheses: Binge-watching is perceived as recreational as long as goal conflicts and feelings of guilt can be avoided. Well-being, on the other hand, is positively affected by binge-watching-induced increases in perceived autonomy. These results corroborate the central role of self-determination as a link between media reception, media enjoyment, and psychological well-being.  相似文献

This study examines how social comparison information provided by video game leaderboards may influence players’ retrospective judgments of autonomy, competence, and relatedness need fulfillment. Participants played a video game and were randomly assigned to receive no postgame feedback or were shown a leaderboard that placed them in the top or bottom quartile of players. Results indicate downward social comparisons increase enjoyment by increasing competence and relatedness perceptions. However, upward comparisons did not have an opposite effect, nor did either type of social comparison influence players’ autonomy perceptions. Implications for applying Self-Determination Theory to video game enjoyment in the context of social comparison feedback is discussed.  相似文献

Altmetrics是Web2.0时代一种新兴的计量方法并受到国内外学者的认同、关注与研究。识别国际Altmetrics主题演进动态,发现国际Altmetrics知识演化规律,从而为我国Altmetrics的研究提供借鉴或参考。基于此,本文运用Sci MAT软件绘制了Wo S中的2012—2015年Altmetrics研究文献的覆盖图、演进图、战略图三种知识图谱,以期识别出国际Altmetrics演进动态。研究发现:Altmetrics研究以传统计量学的理论方法为基础,其理论体系覆盖文献计量学、科学计量学、信息计量学和网络计量学;研究主题由学术影响研究向学术影响研究和社会影响研究转变;计量数据由引文数据向引文数据和社交媒体数据转换。因此,Altmetrics有着广泛的研究、应用与发展空间,值得研究人员尤其是计量研究人员的关注、重视及研究。  相似文献

从文件生命周期理论到文件连续体理论,档案界对文件运动形式的理解从线性向多维转变。在后现代主义档案观的影响和跨界合作的时代背景下,四维的文件连续体理论模型逐渐向五维演变。本文以加拿大档案学者勒梅教授及其团队提出的“第五维度理论”为基础,认为应该充分考虑利用者在档案工作流程中的作用,同时将对档案的“探索”性开发看成是对文件连续体理论模型的第五个维度。  相似文献

Inconsistency is often considered an indication of deceit. The conceptualization of consistency used in deception research, however, has not made a clear distinction between two concepts long differentiated by philosophers: coherence and correspondence. The existing literature suggests that coherence is not generally useful for deception detection. Correspondence, however, appears to be quite useful. The present research developed a model of how correspondence is utilized to make judgments, and this article reports on four studies designed to elaborate on the model. The results suggest that judges attend strongly to correspondence and that they do so in an additive fashion. As noncorrespondent information accumulates, an increasingly smaller proportion of judges make truthful assessments of guilty suspects. This work provides a basic framework for examining how information is utilized to make deception judgments and forms the correspondence and coherence module of truth-default theory.  相似文献

This article explores people’s susceptibility to political deception. Participants watched a news interview in which a politician either answered all the questions or deceptively evaded a question. In Study 1 (n = 202), deception is perceived through the dodge being irrelevant for voters who do not identify with the politician. In Study 2 (n = 618), partisan voters consider the politician more deceptive, and acting more deceptively, when the politician has their opposing party affiliation, independent of whether he dodges. When the politician shares their party identification, voters identify with the politician more and consider his responses more relevant. Findings are consistent with theoretical positions of identification, the cooperative principle, and social identity.  相似文献

The development of artificial intelligence (AI) technology expands the boundary of business practice, inducing the emergence and application of business intelligence (BI) that has promoted the transformation of information techniques to optimize business decision and operation. However, there is a lack of theoretical consensus and measurement of the technology embedded in BI at present. This study exploratively develops the Sense-Transform-Drive (STD) conceptual model of BI based on dynamic capabilities theory and organizational evolutionary theory to explain the core BI capabilities. By using factoring analysis and structural equation modeling analysis, we extract the latent constructs and empirically verify the validity of the STD model and further examine the correlation and mode of interaction of the three core BI capabilities and the impact of BI application on firm performance in the real economy with a sample contextual to Chinese business practices. The study results show that there are direct and high-intensity cumulative positive effects among the structural components of the STD conceptual model and BI-related dynamic capabilities can enhance operating efficiency and firm performance.  相似文献
