Seniors’ usage of mobile social network sites

Seniors’ usage of mobile social network sites: Applying theories of innovation diffusion and uses and gratifications Myung Ja Kim, Choong-Ki Lee, Noshir S. Contractor Abstract: Seniors are substantial users of mobile devices to communicate and participate in mobile social network sites (MSNS) to interact, but there has been little theoretically based understanding of what motivates seniors’ use of MSNS for tourism. To bridge the gap, this study applied the theory of the diffusion of innovations as well as the theory of uses and gratifications to explain why seniors use MSNS. Key explanatory variables included site attachment and authentic experience. Results indicate that the effect of innovation diffusion on authentic experience was greater than on site attachment. The effect of uses and gratifications was also greater on authentic experience than on site attachment. In addition, this study examined the moderating role between purchase and non-purchase groups. The effects of uses and gratifications on site attachment and authentic experience were stronger in the purchase group than in the nonpurchase group, while on the other hand, the effects of innovation diffusion on site attachment and authentic experience were stronger in the non-purchase group than ...

Aaron M. Schecter, SONIC alumnus and Ph.D. in Industrial Engineering and Management Science, received the 2018 J. Richard Hackman Award for his Ph.D. dissertation at INGroup 2018. The conference recognizes recent graduate students whose dissertation shows the greatest potential to advance the study of groups. His dissertation entitled “It’s About Time: Theorizing the Antecedents and Outcomes of Dynamic Processes in Teams and Multiteam Systems” presented a sophisticated theoretical analysis combined with four controlled experimental studies. The relational event modeling framework provided a new conceptual and methodological approach to studying teams process in Multi-Team Systems. At the award ceremony, Schecter’s dissertation was described as “a clear and innovative interdisciplinary approach by contributing to the advancement of team research methodology.” Dr. Schecter, who is an assistant professor at the Terry College of business at the University of Georgia, received a commemorative plaque, a $1,000 check, and an invitation to present his dissertation in a featured session at the following year’s INGRoup conference, in Portugal.

Multidimensional Understanding of Tie Strength

06
Jul

An article “The weakness of tie strength” in the current issue of Social Networks unpacked three elements related to the strength of ties: capacity, frequency, and redundancy. The case with an email network shows that the three elements are not highly correlated and are likely to reflect different dimensions of ties. This multidimensional view may explain some unexpected empirical findings. For example, Garg and Telang (forthcoming in Management Science) found that strong ties in online social networks play a significant role in job search and weak ties are ineffective. Weak ties may generate some job information, but only strong ties lead to actions such as referrals.
