Online Interaction effects of storytelling in an internet breast cancer support group
Journal of social intervention: Theory and Practice, 2008Co-Authors: Mette Terp Hoybe, Christoffer Johansen, Tine TjornhojthomsenAbstract:The internet provides new ways of forming social relationships among people with breast cancer and is increasingly used for this purpose. This qualitative study, using ethnographic case-study method, aimed to explore how support groups on the internet can break the social isolation that follows cancer and chronic pain, by analysing the storytelling emerging on the Scandinavian Breast Cancer Mailing list. Using participant observation and face-to-face or Online interviews of participants, we investigated the motivations of 15 women who chose the internet to counteract social isolation after breast cancer. The results showed that the women were empowered by the exchanges of knowledge and experience within the support group. The internet was considered a means for finding ways of living with breast cancer. Our study suggests that internet support groups have important potential for the rehabilitation of cancer patients.

meaningful Interaction in web based learning a social constructivist interpretation
Internet and Higher Education, 2007Co-Authors: Younghee Woo, Thomas C ReevesAbstract:Interaction is an essential ingredient in any learning process. However, every Interaction does not lead to increased learning. When Interaction has a direct influence on learners' intellectual growth, we can say the Interaction is meaningful. The precise meaning of meaningful Interaction is strongly related to the learning theories underlying the development of particular learning environments. The primary goal of this paper is to re-conceptualize Online Interaction in terms of meaningful learning based on the learning theory known as social constructivism. Analyzing Interaction through this theoretical framework may yield design principles needed to improve the quality of Web-based learning environments. A secondary goal of this paper is to present the implications of meaningful Online Interaction for researchers and developers.

a social aware framework for efficient information dissemination in wireless ad hoc networks
IEEE Communications Magazine, 2017Co-Authors: Yanru Zhang, Lingyang Song, Chunxiao Jiang, Nguyen H Tran, Zaher Dawy, Zhu HanAbstract:In wireless ad hoc networks, each node participates in routing by forwarding data to other nodes without a pre-existing infrastructure. Particularly, with the wide adoption of smart devices, the concept of smartphone ad hoc networks (SPANs) has evolved to enable alternate means for information sharing. Using unlicensed frequency spectrum and short-range wireless technologies, a SPAN enables a new paradigm of applications and thus is seen as an attractive component in future wireless networks. In a SPAN, smartphones form local peer-to-peer networks to cooperate and share information efficiently. Recent studies have shown that if the users’ social relations are considered while designing cooperation schemes and protocols in SPANs, the cooperation initialization and content dissemination can be notably improved to increase the overall network efficiency and communications reliability. In this article, we present a social-aware framework for optimizing SPANs by exploiting two layers: users’ relationships in the Online social network layer and users’ offline connections and Interactions in the physical wireless network layer. The Online content popularity distribution is also studied as a result of the users’ Online Interaction profiles. In the end, we integrate both Online and offline layers, and discuss possible applications to further enhance the network performance.

a causal loop approach to uncover interrelationship of student Online Interaction and engagement and their contributing factors
Research in Learning Technology, 2019Co-Authors: Afrooz Purarjomandlangrudi, David ChenAbstract:Advances in technology reinforce the imperative to obtain further insight into the factors that impact Online Interaction in Online environments. Even though past researchers have extracted factors impacting student Online Interaction and engagement, there is a lack of research that uncovers the dynamics of these relationships and investigates the impact of a comprehensive set of factors on student Online Interaction at the same time. Thus, this paper seeks to fill this gap by employing a causal loop approach to uncover the interrelationships of these factors that contribute to a positive impact on students’ learning outcomes, and to evaluate satisfaction and engagement in Online courses by focussing on students’ Online Interaction. To this end, a rich qualitative data set was obtained from an Online focus group consisting of students from a large Online course, and a thematic analysis was conducted resulting in identifying different factors that played a role in the topic under study. More importantly, causal loop modelling was used to model these factors and their causal interrelationships.

investigating the drivers of student Interaction and engagement in Online courses a study of state of the art
Informatics in education, 2016Co-Authors: Afrooz Purarjomandlangrudi, David Chen, Anne NguyenAbstract:Online learning has become a widespread method for providing learning at different levels of education. It has facilitated the learning in many ways and made it more flexible and available by providing learners with more opportunities to learn information, further access to different learning resources, and collaboration rather than face-to-face learning. In spite of these benefits and rapid growth of Online education, success and persistence in such courses is one the important aspects of Online learning research and it relies on different factors. Therefore investigating the reasons of students' dropout of an Online education course or program and its contributing factors is essential in this area. One of the most barriers in Online learning system is lack of Interactions. In learning, Interaction between students themselves, with the course content, and course instructors is important for conveying information, enhancing teaching quality, give directions, and many more functions. The aim of this research is to review the literature to propose a clearer picture of studies have been conducted regarding Online Interaction and factors that impact it in Online education systems.
