In this article we take up a critique of the concept of Communities of Practice voiced by several authors, who suggest that network may provide a better metaphor to understand social forms of organisation and learning. This critique we situate within a broader theoretical movement in socio-cultural learning theories. From this we identify some theoretical and analytical challenges to the networ...

This paper explores how theories of diversity and intersectionality can improve our understandings of the lives of older lesbian, gay and bisexual (LGB) adults. In so doing, it argues that theories of diversity help us to understand both the structural constraints and the advantages that may arise from being an older LGB adult. However, these theories are unable to fully account for differences...

In this paper, we show how to reduce the Penrose conjecture to the known Riemannian Penrose inequality case whenever certain geometrically motivated systems of equations can be solved. Whether or not these special systems of equations have general existence theories is therefore an important open problem. The key tool in our method is the derivation of a new identity which we call the generaliz...

Identity fusion is a visceral sense of “oneness” with a group and its individual members that motivates personally costly, pro-group behaviors. Past approaches, most notably social identity theory, have assumed that when people align with groups, the group category eclipses both the personal self and the relationships among individual group members. Also, social identity researchers have focuse...

We develop a theory of moral behavior, individual and collective, based on a general model of identity in which people care about “who they are” and infer their own values from past choices. The model sheds light on many empirical puzzles inconsistent with earlier approaches. Identity investments respond nonmonotonically to recent acts or threats, and taboos on mere thoughts arise to protect be...

Drawing on ideas from identity control theory and coping theory and on a diverse range of social psychology literature, we propose an integrative theoretical framework that unpacks and traces the processes by which information technology comes to affect users’ identity. We define four types of strategies (acting on the situation, adjusting the self, cathartic practices and distancing) through w...
