someone else the misuse that what was shared and/or take credit somewhere in the team or organisation. As such, interpersonal relationships and ´fair´ exchange appear important, as does some kind of mechanism for rewards and gratitude (possibly organisation-wide), as these impact on individual professional discretion and the degree and success of exchange. Citizenship behavior Social exchange theory is a theoretical explanation for organizational citizenship behavior. This study examines a model of clear leadership and relational building between head and teachers as antecedents, and organizational citizenship behavior as a consequence of teacher–school exchange. Citizenship behavior can also be shown with employees and their employers.This is shown through organizational identification which plays an important role in organizational citizenship behavior. An employees identification with their employer plays a significant role in supporting and promoting organized citizenship behavior, serving as a mediating mechanism with citizenship behaviors, perceived organizational justice, and organizational support based on both the social exchange and social identity theory. Online social networking and self-disclosure Understanding interpersonal disclosure in online social networking is an ideal application of social networking theory. Researchers have leveraged SET to explain self-disclosure in a cross-cultural context of French and British working professionals. They discover that reciprocation is the primary benefit of self-disclosure, whereas risk is the foundational cost of self-disclosure. They find that positive social influence to use an online community increases online community self-disclosure; reciprocity increases self-disclosure; online community trust increases self-disclosure; and privacy risk beliefs decrease self-disclosure. Meanwhile, a tendency toward collectivism increases self-disclosure. Similar research also leveraged SET to examine privacy concerns versus desire for interpersonal awareness in driving the use of self-disclosure technologies in the context of instant messaging. This study was also a cross-cultural study, but instead compared US and Chinese participants. Affect theory The actors in social exchange are normally viewed as unemotional beings who have information, cognitively process it, and make decisions concerning the pattern and nature of exchange with others. Affect theory of social exchange complements social exchange theory by incorporating emotion as part of the exchange process. Formalized by Lawler (2001), the affect theory examines the structural conditions of exchange that produce emotions and feelings and then identifies how individuals attribute these emotions to different social units (exchange partners, groups, or networks). These attributions of emotion, in turn, dictate how strongly individuals feel attached to their partners or groups, which drives collectively oriented behavior and commitment to the
