文化、权力与多元性:关于媒介批评学科体系建设的思考

随着大众传媒与社会生活的关系日益紧密,旨在为观察、分析、阐释错综复杂的媒介现象提供理论与方法的传播学分支学科——媒介批评——的重要性正日益凸显。然而,目前我国的媒介批评学科体系中存在着包罗万象、还原主义和重理论轻实践的三种倾向,制约着媒介批评学科的发展。本文认为,媒介批评学科体系的建构需在文化、权力分配与多元性的框架内展开,赋予该学科以真正的批评力量,切实推动社会变迁。     

媒介治理:作为善治的传播研究

西方信息社会的传播权利运动的兴起带动了传播学界"媒介治理"的研究热潮。通过社会人类学的"功能-符号"路径,媒介治理关注了传播的信息界面、产业界面、符号界面和关系界面,综合了传播系统的界内研究和界外研究,代表了一种新的传播研究范式。作为跨学科的交叉研究,"媒介治理"在研究取向上呈现出学科的交叉性:深层生态学路径、公共选择路径、协商民主路径是研究"媒介治理"的基本路径。媒介治理的研究是一种"灰色系统"的信息论,是第三种文化思维范式的代表。媒介治理理论研究尚处于起步阶段,需要进一步提供具有解释力的基本假设,实现叙事的连贯性和必要的逻辑建构。     

The effect of interactivity on initial interactions: the influence of information valence and modality and information richness on computer‐mediated interaction

Research investigating relationship development through computer‐mediated channels has failed to acknowledge the importance of initial interactions. Increasingly, multimodal forms of communication, such as audio‐ and videoconferencing, in addition to text‐only formats have emerged on socially oriented websites designed for relationship initiation. Utilizing the principle of interactivity as a conceptual framework, the present study investigates whether increased structural interactivity provided by the additional aural and visual modalities influences initial interaction processes and outcomes online. The results indicate that increased availability of nonverbal modalities, combined with the valence of the information acquired, significantly affected interaction involvement and mutuality, which are markers of processual interactivity, as well as the interaction outcomes of uncertainty, predicted outcome value, and information seeking. Additional analysis revealed that mutuality mediated the effect of richness on postinteraction uncertainty level and the evaluations of future relationship potential.     

A Call to Educate,Participate, Invoke and Indict: Understanding the Communication of Online Hate Groups

This study analyzes the messages in hate group websites using a grounded theory approach. Through this process of interpretive inquiry we propose four prominent themes—educate, participate, invoke, and indict—that characterize the messages examined in 21 hate groups. These message themes speak to the: (a) education of members and external publics; (b) participation within the group and in the public realm; (c) invocation of divine calling and privilege; and (d) indictment of external groups including the government, media, and entertainment industries, and other extremist sects. In advancing a substantive grounded theory of online hate group communication, we also explore the potential of these themes to ostensibly reinforce the hate group's identity, reduce external threats, and recruit new members.     

Geographical Proximity,Cultural Imperialism,and the Cultivation Effect

This work investigates the influence of geographical proximity on the cultivation effect in the context of cultural imperialism. A content analysis of prime-time programming (n=63 hours) is used to compose questions about the prevalence of different occupations in the USA and Israel. A sample of 655 students answered these questions. Viewing of American programming was significantly correlated with a tendency to hold a biased estimation of the prevalence of certain occupations in America in a manner that resembles the world of TV content. Viewing of Israeli programs had no such impact on the estimation of occupation prevalence in Israel. General viewing had no influence on the estimations made about any of the countries.     

Relational Communication in Computer-Mediated Interaction Revisited: A Comparison of Participant–Observer Perspectives

Studies of online environments estimate that the majority of members in online forums do not contribute to ongoing discussions and only observe or “lurk” (e.g., Nonnecke & Preece, 2000). Despite the prevalence of this form of information acquisition, direct comparisons between the experiences of these “observers” (or “lurkers”) and active participants are lacking. The present research draws on previous research examining perceptual differences between participants and observers as well as social information processing theory (Walther, 1992) and reports on three studies examining such differences in computer-mediated communication (CMC). Study 1 examined the effects in the context of interpersonal interaction in synchronous CMC. Study 2 examined the effects in the context of group interaction in both synchronous and asynchronous CMC. Study 3 replicated and extended the results of the previous studies across two time periods. The overall results (a) support the presence of participant–observer differences in CMC, (b) show that the presence of anticipated future interaction moderates said differences, and (c) provide mixed evidence that participant and observer interpretations of relational messages converge over time.
