Purpose -Drawing upon the knowledge sharing model, the purpose of this paper is to identify personal and environmental antecedents to information sharing on social networking sites (SNSs) and examines the interaction effects between the two factors. Design/methodology/approach -Data were collected via online survey with college students. Hierarchical multiple regressions were performed to test hypotheses and examine research questions. Findings -With regard to environmental factors, the more users perceive their audience to be a collection of weak ties, the more likely they are to share information on SNSs, independent of the size of their networks. Personal factors such as information self-efficacy, positive social outcome expectations, and sharing enjoyment feelings were found to be significant predictors of sharing activities. In addition, a significant interaction effect was found such that the effects of social outcome expectations on sharing activities on SNSs are manifested to a greater extent when users perceive their audience as weak ties rather than strong ties. Originality/value -This study extends the knowledge sharing model literature by applying it to the SNS context and advances SNS research by taking into consideration both environmental factors and personal factors and their interactions.

Results of the study suggest racial differences still exist when it comes to attitudes toward homosexuality in the United States. Findings indicate Black individuals hold significantly less favorable attitudes toward lesbian/gay/bisexual (LGB) individuals than non-Hispanic White individuals but not Hispanics, after controlling for demographics. Hispanic individuals' attitudes toward LGBs were not significantly different from those of non-Hispanic Whites. Despite less favorable attitudes toward LGBs, however, Black Americans display a significantly lower likelihood of engaging in LGB-directed microaggressions than both non-Hispanic Whites and Hispanics. Finally, the results of the study indicate that as non-Hispanic White individuals' ethnic identity gets stronger, their likelihood of engaging in microaggressions toward LGBs increases, more so than Black or Hispanic individuals.
