This study aimed to investigate the impact of social networks on learning requests by Arab undergraduate EFL students.

Furthermore, both types of requests (i.e. direct and indirect) have been compared under the same condition. A total of 40 Saudi EFL learners participated in this study. Their scores in the pre-test and post-test were compared.

Results of the post-tests indicated that the experimental groups' performance significantly outscored the control groups. However, no significant difference was reported between the two experimental groups (i.e. direct and indirect).

Requests, as a component of pragmatics, have been investigated extensively in the literature to aid second/foreign language learning. However, little is known about the manner by which social networks could foster learning requests.

This study aims to examine direct effects of qualified team gatekeepers on absorptive capacity (AC), and the mediating roles of combinative capabilities – knowledge integration capability (KIC) and interteam coordination.

A social networking analysis was used to analyze a unique data set collected from all members of 32 Japanese research and development (R&D) teams to identify key individuals who perform daily gatekeeping functions. This study analyzed the data through partial least squares structural equation modeling with higher-order latent variables. Finally, cross-validation tests were used with holdout samples to test the model’s predictive validity.

Qualified gatekeepers directly contribute to teams’ realized AC but not to their potential AC. Furthermore, qualified gatekeepers can improve their teams’ capability to absorb and exploit external knowledge by facilitating their capability to consolidate knowledge, that is, its KIC and interteam coordination.

Unlike prior research that asks top managers to identify team gatekeepers, this study used social network analysis to identify these vital individuals. This study provides a new framework indicating how qualified gatekeepers impact the AC of R&D teams through the examination of both the direct and indirect paths of gatekeeping abilities, two combinative capabilities as mediators and team AC.
