This study examines the effects of the Big Five personality traits (Neurotics vs. Extroversion vs. Openness vs. Conscientiousness vs. Agreeableness) and strangers’ gender in affecting Facebook users’ decisions to accept (or ignore) the stranger’s friend request. Results showed that gender of the stranger and the personality match between participant and stranger jointly affect the decision to accept the stranger as friend on Facebook. Most of the participants accepted the stranger’s friend request based on textual cues that were displayed in the friend request message. This finding supported Social Information Processing theory, suggesting that impression formation of the stranger was not constrained to the lack of nonverbal cues online. Moreover, participants were more likely to accept the stranger’s friend request when the participant’s and stranger’s personalities matched. This effect was more pronounced when the stranger was a female. Participants accepted female stranger’s friend request due to the inflated perception of stereotypical female characteristics, which supports the Hyperpersonal Perspective.展开更多

Most existing studies take a greedy scheme in data forwarding process, i.e., only nodes with higher utility values than current carriers can be selected as relays. They lack an in-depth investigation on the main features of the optimal paths in Epidemic. These features are vital to any forwarding scheme that tends to make a trade-off between packet delivery delay and cost. This is mainly because Epidemic provides an upper bound on cost and a lower bound on delivery delay. Therefore, a deep understanding of these features is useful to make informed forwarding decisions. In this paper, we try to explore these features by observing the roles of different social relationships in the optimal paths through a set of real datasets. These datasets provide evidence that strangers have two sides in data forwarding process, and that the importance of strangers shows a decreasing trend along the forwarding paths. Using this heuristic knowledge, we propose STRON, a distributed and lightweight forwarding scheme. The distributed feature makes it very suitable for opportunistic scenarios and the low communication and computation features make it easy to be integrated with state-of-the-art work. The trace-driven simulations obviously confirm its effectiveness, especially in terms of packet delivery delay and cost.展开更多
