This paper discusses the application of social network sites in building an interactive English reading community under the guidance of the constructivist learning theory and its influence on the learners' English reading. This SNS-aided reading community puts the students as the center and the teacher the guide, embodying students' subjectivity, equality, and interactivity. The study shows that the interactive English reading community can motivate students to read, improve their reading skills, and thus develop a new SNS-aided English reading model for English learners.展开更多

Cyworld was one of the most successful SNSs in the world, but its international expansion efforts failed. Facebook's open technology has had considerable influence on various sectors of the economy and society and allowed it to become a dominant SNS at the global level, whereas Cyworld has remained a local SNS. Facebook's open platform and application programming interface (API) pose a serious challenge to Cyworld's walled-garden approach. Cyworld is based on strong ties fostering close relationships, whereas Facebook expands social networks through its open and weak ties and has more network power than Cyworld. Therefore, openness is the main reason behind the rise of Facebook and the fall of Cyworld.展开更多

As known from the main business literature, the social network represents one of the most important instrument to improve the company fame by strengthening the affection of customers to the brand. For this reason, some companies use these tools to build relations and contacts with customers all over the world. The population of social networks users is made, for the most parts, of youngsters (people belonging to the 13-30 years old cluster). In the last years, with the social web networking, social communication lost the exclusive social meaning and social network sites become strategic instruments for the construction of powerful relations that connect people with people and people with firms. This work is aimed at clarifying the genesis and the evolution of the relations between companies and potential customers, focusing on the tools used by the firm to achieve their marketing goals through social network sites (SNSs). First of all, the work proposes the recognition of some studies about the origin of web social network and their links with marketing strategies. Secondly, it considers marketing goals achieved from any companies through social networking with a particular focus on advertising through web social networking.展开更多

This research aims to investigate the factors which influence knowledge contribution behavior of social networking sites(SNS) users.Design/methodology/approach: The data were obtained from an online survey of 251 social networking sites users. Structural equation modeling analysis was used to validate the proposed model.Findings: Our survey shows that the individuals' motivation for knowledge contribution,their capability of contributing knowledge,interpersonal trust and their own habits positively influence their knowledge contribution behavior,but reward does not significantly influence knowledge contribution in the online virtual community.Research limitations: Respondents of our online survey are mainly undergraduate and graduate students. A limited sample group cannot represent all of the population. A larger survey involving more SNS users may be useful.Practical implications: The results have provided some theoretical basis for promoting knowledge contribution and user viscosity.Originality/value: Few studies have investigated the impact of social influence and user habits on knowledge contribution behavior of SNS users. This study can make a theoretical contribution by examining how the social influence processes and habits affect one's knowledge contribution behavior using online communities.展开更多

Employing qualitative approach, this study attempts to uncover the cross-cultural differences in motivations and behavioral patterns for using SNSs among the Korean and American users. The finding of this study shows the explicit differences in the motivations and strategies for using SNSs between Korean and American users, which is supported by the independent and interdependent self-construals theory proposed by Markus and Kitayama (1991). The motivational themes and usage patterns emerged from Korean participants are more other- or relationship-focused, pursuing social/emotional support, while those of Americans are more ego- or self-focused, pertaining to entertainment or information seeking.展开更多

The interactions between two non-governmental organizations (NGOs) and rural beneficiaries in Isinya, Kajiado County, provide case studies of how NGOs modernize their outreach via new media and how beneficiaries respond to the change. The research was not only concerned with the presence of information technology (IT) and online facilities in remote and deprived locations. It also evaluated responses to the replacement of person-to-person contact with technologies, such as social media, the Internet, Compact Disc-Read Only Memory (CD-ROMs), and Digital Versatile Disc (DVDs). Conducted in four focus groups, the research evaluated the uptake of new media technologies by beneficiaries following the transition, asked whether beneficiaries engaged with the materials being communicated, and assessed whether this confluence of technology and culture had eased the flow of communication, or unsettled it. Evidence of discomfort among the older (over 50-year-old) beneficiaries stemmed from fear of failure to master the technologies and a desire for a continuation of regular interpersonal interaction with the NGO field officers (whose field trips were scaled back in preference of computer-mediated communication). However, younger (under 40-year-old) beneficiaries were less insistent on regular interpersonal visits and were appreciative of the use of technology, and of the building of Maarifa Centres to give the beneficiaries free access to internet, DVDs, and hard drive-based information materials. Another demographic, beneficiaries aged between 40 and 50 years old, said they were not comfortable with the change and wanted the interpersonal interaction to continue, but were open to a longer-term transition once the beneficiaries were all conversant with the uses of the new technologies. The study recommends a better managed transition that accommodated the beneficiaries’ fears, misgivings, and cultural preference for verbal, face-to-face consultation.展开更多

As a result, many Afi'ican American women lack knowledge about how to care for their naturally kinky hair because straightened hair has been the standard and norm. Therefore, women wearing natural hair had to seek support and education outside of their immediate community via social networking sites. Through a participatory culture framework via an Afrocentric lens, the results revealed that producers of these sites became the needed support and comfort that the natural hair community was missing. Through communication with these producers and their sites, a space was created where women began to appreciate and love their natural hair.展开更多
