Online Social Networks (OSNs), such as Facebook and LinkedIn, are now widely used. They count users in the hundreds of millions. This paper surveys popular OSNs in order to identify and present a pattern of recurring requirements, and a model of that pattern in the i-star requirements modelling language. The pattern can serve as a starting point for requirements engineering of new OSNs.

ABSTRACTIn less than a decade, online social networks (OSN) have revolutionised social communications worldwide. Nowhere is this more evident than amongst today's young consumers, so called millennial teens, who have snapped up these identity‐making digital social spaces claiming them as their own. This article examines the range of strategies and resources employed by UK millennials for self‐presentation in OSNs and the resultant implications on teenage identity construction in the postmodern era. An in‐depth qualitative content analysis of 20 teen OSN profiles was conducted and analysed against extant theories of impression management, self‐identity and self‐presentation.Our analysis revealed that millennials were deeply immersed in self‐presentation activities. They employed a wide range of 'intentional' self‐presentation strategies and drew on colour, design and symbolism to create complex, elaborate and decorative versions of self, which we have termed the 'aesthetic self'. OSNs satisfy teen needs for intense social interaction with their peers, offer potential for copious identity experimentation and reduce the need to consume physical symbolic items in order to convey meaning, thus acting as an accelerator in the teen identity‐making process.Our findings extend existing frameworks for teenage self‐identity theory and moreover have significant implications for future marketing practice, particularly sourcing consumer behaviour data, brand management and marketing communications strategies.Copyright © 2013 John Wiley & Sons, Ltd.

In recent years online communities have become popular as a way for dispersed members to interact and share ideas. However, there is limited research on the systemic analysis of such groups. In this paper the authors draw on systems research to suggest that one can only understand or interpret data gathered from an online group by assigning meaning to it in the context of a wider 'system'. Here they demonstrate that conventional methods of offline group analysis are ineffective when applied within online communities. As an alternative they offer a means of importing big data from a community on social media and identifying the kinds of information that would be typically gathered during an offline systemic analysis into a problem situation. The authors offer as an aid to managers a framework that identifies appropriate Social Network Analysis (SNA) metrics (from the imported data) that corresponds to soft systems concepts. During their analysis of a community on Twitter they found that their ideas provided a way to gain a more holistic understanding of the roles and interactions in a virtual community. The authors also found examples of the use of informal power in the Twitter community under study. This information can be useful to managers when producing marketing plans, during product development and when identifying opportunities for growth.

The research aimed to explore the status, usage, and roles of social networking sites in intercultural communication of different regional groups in different contexts, and the impacts on interpersonal communication in Thai culture and on communication across cultures, including guidelines towards effective and appropriate usage of social networking sites in Thai society. The study was conducted by documentary research, focus group interview and survey questionnaires with students, governmental officers, and multinational company staffs, including in-depth interviews with scholars and professionals. The results are as follows: 1) The subjects use "facebook" the most (88.75%) at "seldom" level (30.00%) to contact their present foreign friends or colleagues at school or in the workplace (46.80%). The most mentioned purpose of using SNS is to maintain their relationship (84.31%). 2) Increased roles of SNS usage in intercultural and cross cultural communication are found in various contexts and circles, i.e internal communication and organizational management, learning enhancement in educational and business circles, utilization for marketing and public relations, expansion of network and cooperation in social and political movement, and tools for mass media work across borders. 3) SNS usage is found to affect Thai people's values and personality. On the other hand, it enhances their cultural learning and increase their positive attitude in intercultural communication. 4) A number of guidelines towards effective and appropriate SNS usage in Thai society are proposed in this study. ; การวิจัยนี้มีวัตถุประสงค์เพื่อสำรวจสถานการณ์ ลักษณะการใช้และบทบาทการใช้เว็บไซต์เครือข่ายสังคมในการสื่อสารระหว่างวัฒนธรรมในบริบทต่างๆ ของคนกลุ่มต่างๆ ในแต่ละภูมิภาคในสังคมไทย ศึกษาผลกระทบของการใช้เว็บไซต์และเครือข่ายสังคมออนไลน์ต่อรูปแบบและวิธีการสื่อสารระหว่างบุคคลในวัฒนธรรมไทยและต่อการสื่อสารกับคนต่างวัฒนธรรมรวมถึงหาแนวทางการใช้เครือข่ายสังคมออนไลน์ในปริบทการสื่อสารระหว่างวัฒนธรรมอย่างมีประสิทธิภาพและเหมาะสมในสังคมไทย โดยศึกษาจากเอกสาร สัมภาษณ์กลุ่มเฉพาะ และสำรวจด้วยแบบสอบถามจาก กลุ่มตัวอย่าง ได้แก่ นักเรียน/นักศึกษา ข้าราชการ และพนักงานบริษัทเอกชนข้ามชาติ รวมถึงสัมภาษณ์เชิงลึกนักวิชาการและนักวิชาชีพ ผลการวิจัยพบว่า 1) กลุ่มตัวอย่างใช้เฟซบุ๊กมากที่สุด (ร้อยละ 88.75) กับเพื่อนต่างชาติที่สถานศึกษาหรือที่ทำงานในปัจจุบัน (ร้อยละ 46.80) ในระดับนานๆ ครั้ง (ร้อยละ 30.00) เพื่อรักษาความสัมพันธ์มากที่สุด (ร้อยละ 84.31) 2) มีการใช้เว็บไซต์เครือข่ายสังคมในการสื่อสารระหว่างวัฒนธรรมและข้ามวัฒนธรรมในบริบทและวงการต่างๆ มากขึ้น เช่น การบริหารและสื่อสารภายในองค์กร การเพิ่มช่องทางการเรียนรู้เพื่อการศึกษาวัฒนธรรมทั้งในวงการศึกษาและทางธุรกิจ การใช้เป็นเครื่องมือทางตลาดและประชาสัมพันธ์ การขยายเครือข่ายและความร่วมมือในการเคลื่อนไหวทางสังคมและการเมือง รวมถึงการใช้เป็นเครื่องมือในการทำงานของสื่อมวลชนข้ามชาติ ฯลฯ 3) พบการใช้เว็บไซต์เครือข่ายสังคมมีผลต่อการเปลี่ยนแปลงค่านิยมและบุคลิกภาพของคนไทย ขณะเดียวกันมีผลต่อการเรียนรู้และสร้างทัศนคติเชิงบวกในการสื่อสารกับคนต่างวัฒนธรรมมากขึ้น 4) แนวทางในการใช้เว็บไซต์เครือข่ายสังคมอย่างมีประสิทธิภาพและเหมาะสมในสังคมไทยหลายประการได้ถูกนำเสนอในงานวิจัยนี้

Enormous popularity of Social Networking Sites has introduced a great number of privacy risks. Even the most popular of all the social networking sites have characterized access control policies in terms of explicit tracking of the interpersonal relationships between the subjects, objects and their inter relation. In this paper we present a novel paradigm that accounts for a secure, yet sociable information flow model based on access control policies. We took advantage of real time success of the access control security policies in operating systems by implementing them on online social networks at the mandatory level so that the user's privacy does not have to be at stake by the growth of social network and activities or by the level of user understanding of the privacy settings provided by the social networking sites based on discretionary access control. We used Facebook and Google+ as case study and implemented the security policy in SecureWall to mitigate possible privacy leakage scenarios observed. We have implemented Chinese wall policy for community level privacy, Bell la-Padulla access control model to assure confidentiality to the user and Biba Access control model for providing Integrity. Since Bell la-Padulla and Biba models are basically meant to serve military security and therefore can risk sociability, we have combined the two models using Lipner Security Matrix in order to provide security without risking sociability. Our research can be adopted by online social networking sites for the mandatory level security especially for social networking in organizational specific activities.

The phenomenon of online social networking during the age of the web creates an era known as the 'Online Social Network Era'. Whilst the advantages of the online social network are numerous, the drawbacks of online social network are also worrying. The explosion of the use of online social networks creates avenues for cyber criminals to commit crimes online, due to the rise of information technology and Internet use, which results in the growth of the Internet society which includes the children. The children, who are in need of 'extra' protection, are among the community in the online social network, and they are exposed to the cyber crimes which may be committed against them. This article seeks to explore and analyse the position on the protection of the children in the online society; and the focus is in Malaysia while other jurisdictions are referred as source of critique. The position in Malaysia is looked into before the introduction of the Sexual Offences Against Children Act 2017. It is found that, in the Online Social Network Era, there are inadequate protections for children in the Malaysian legal framework before the introduction of the Act. The effectiveness of the Act which is already passed by the Parliament but yet to be enforced, is yet to be seen.
