Previous research in computer-mediated communication's effect on social networks has generated questions about the role of weak ties in what was assumed to be a unique affordance of strong ties-obtaining effective social support. Eighty-eight college students completed a questionnaire based on their most recent Facebook status updates and the comments and likes those updates generated. Items queried participants' perception of each response as well as the participants' relationships characteristics with the responder. Strong ties were perceived to have significantly closer relationships and provided significant social support. However, weak tie relationships were more numerous than strong ties and were perceived by participants to provide social support that was equally significant. While the use of Facebook did not erode the importance of strong ties, this study found that traditional understandings of weak ties do not account for the strong social support afforded by weak tie relationships when mediated through social network sites.

Given the important implications of social support on managing volunteers and their organizational commitment, we investigated how members of a Korean immigrant church (N = 178) exchanged two distinctive kinds of social support (i.e., informational and tangible). We used theories of centrality and homophily to hypothesize patterns of social connections among organizational members. Employing exponential random graph modeling (ERGM), the current study estimated the likelihood of age and gender homophily/heterophily in forming supportive ties while simultaneously considering structural parameters. The results of analysis of variance showed that members with higher socioeconomic status and in official staff positions in the church were more central in the informational support exchange. However, ERGM for both types of support networks did not show hypothesized gender and age homophily/heterophily of Korean immigrants' support exchange, suggesting the importance of other potential organizational and cultural influences. The findings shed light on the internal structuring of organizational support networks and suggest practical implications for managing organizational volunteers.

This study explored American job seekers' network of information sources using a random sample. Results revealed a pattern that job seekers segmented information sources by social (ie, personal and professional acquaintances, family and friends), formal (ie, employment agencies, printed advertisements and career events) and online (ie, online pages and social network sites) types. Though online sources were particularly central in the network, job seekers who used one source type did so at the expense of other types of sources. Those who were older and poorer job seekers were more likely to use formal sources, while online sources were used more by job seekers with higher education and Internet efficacy. The discussion offers advice for job seekers and those who coach job search. This study extends strength of weak ties theory by demonstrating the importance of online sources in job search.

In organizational meetings, mobile media are commonly used to hold multiple simultaneous conversations (i.e., multicommunication). This experiment uses video vignettes to test how manager policy (no policy, pro-technology, anti-technology), device use (notepad, laptop, cell phone) and task-acknowledgment (no task-acknowledgment, task-acknowledgment) affect perceptions of meeting multicommunication behavior. US workers ( N = 243) who worked at least 30 hours per week and attended at least one weekly meeting rated relevant outcomes: expectancy violation, communicator evaluation, perceived competence, and meeting effectiveness. Results reveal manager policy and device use both affect multicommunication perceptions, with mobile phones generating the highest expectancy violation and lowest evaluation of the communicator and meeting effectiveness. Surprisingly, there was no effect for task-acknowledgment; however, a match between manager policy and task-acknowledgment affected evaluations. This paper unifies past evidence about multicommunication under the expectancy violations framework, extends theoretical understandings of mobile media use at work, and suggests practical implications for technology use in unfamiliar workplace situations.
