Understanding the Nature,Uses, and Gratifications of Social Television: Implications for Developing Viewer Engagement and Network Loyalty

This study employed an online survey (N = 310) to explore how viewers’ motivations for social TV participation influence their involvement in social TV activities, their program commitment, and network loyalty. Findings show that social infotainment and social companionship are the primary motivations of social TV participation. However, only social infotainment significantly predicts the intensity of viewers’ social TV usage, which has a positive influence on program commitment and network loyalty. Additionally, the relationship between social TV usage and network loyalty is partially mediated by program commitment. These findings demonstrate the value of social TV to broadcasters and provide directions for initiating and maintaining long-term relationships with viewers.

Research universities on the ResearchGate social networking site: An examination of institutional differences,research activity level,and social networks formed

As one of the largest active academic social networking sites, ResearchGate (RG) has been utilized by scholars to share publications, seek collaborators, communicate work in progress, and build scholarly reputation. This study collects data from RG users from 61 U.S. research universities at different research activity levels, as categorized by the Carnegie Classification of Institutions of Higher Education, to examine the impact of institutional differences on RG reputational metrics. The results confirm that RG is a research-oriented academic social networking site that closely and realistically mirrors the research activity level of institutions. With an increase in the research activity level of a university, its affiliated RG users tend to have higher RG scores, more publications and citations, and more profile views and followers, while the average number of reads of their publications and followees tend to be lower and fluctuant. In addition, RG users primarily follow others from institutions of a higher research activity level, forming virtual social networks centered around esteemed institutions. The study suggests academic social networks can serve as indicators in evaluation of research activities among research institutions, and such sites can be helpful and credible for acquiring resources, keeping informed about research, and promoting academic influence.     

Photonic orbital angular momentum with controllable orientation

Vortices are whirling disturbances, commonly found in nature, ranging from tremendously small scales in Bose-Einstein condensations to cosmologically colossal scales in spiral galaxies. An optical vortex, generally associated with a spiral phase, can carry orbital angular momentum (OAM). The optical OAM can either be in the longitudinal direction if the spiral phase twists in the spatial domain or in the transverse direction if the phase rotates in the spatiotemporal domain. In this article, we demonstrate the intersection of spatiotemporal vortices and spatial vortices in a wave packet. As a result of this intersection, the wave packet hosts a tilted OAM that provides an additional degree of freedom to the applications that harness the OAM of photons.

基于供需融合理念打造学术期刊转型升级的全媒体经营业态

经营业态总体上反映一个产业的经营结构、供需关系、运营方式和发展战略,其合理性、科学性决定着产业市场运行模式的成败。近20年来我国学术期刊已逐步形成以纸质版、网络与电子版多元发布的全媒体出版产品结构,但这同一内容的2种版本却一直分别由不同的供应链各自定价发行,人为地将一个市场裂解为2个市场,造成了价格脱离价值、市场相互抵消、边际成本上涨、营销模式混乱的状态,严重削弱了期刊的市场主体地位,扭曲了产业生态,牵制了期刊和图书馆等信息服务机构的数字化转型升级与高质量发展。为根本上破解这一制约产业发展的全局性难题,应构建供需合作共赢的“刊-网-馆”融合运营模式,大幅度降低产业运行消耗,打造学术期刊数字版云出版、传播和服务与纸质版集约化生产发行和馆配相结合的全媒体经营业态。
