In recent years, the debate on the problem of causal exclusion has seen an ‘interventionist turn’. Numerous non-reductive physicalists (e.g. Shapiro and Sober 2007) have argued that Woodward’s (2003) interventionist theory of causation provides a means to empirically establish the existence of nonreducible mental-to-physical causation. By contrast, Baumgartner (2010) has presented an interventi...

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...

Knowledge contribution is one of the essential factors for the success of virtual communities (VCs). Although there has been a great deal of research on knowledge management in organizational settings, there is a lack of understanding about the knowledge contributions of individual members in non-organizational settings, especially in VCs. This study examines the knowledge contribution of indiv...

Knowledge contribution is one of the essential factors behind the success of blogging communities (BCs). This research studies knowledge contribution behavior in a BC from the perspective of knowledge contributors and their characteristics using the lens of social identity theory. Social identity theory asserts that individuals are fundamentally motivated to present or communicate their identit...

The key result in this paper is a proof of a large class of identities, generalizing the Capelli identity [Cl. The Capelli identity is a centerpiece of 19th century invariant theory. It asserts the equality of two differential operators on the n2-dimensional space M(n, R) of n x n real matrices. Let E, denote the ijth elementary matrix, let xii denote the linear functions on M(n, R) dual to E,,...

Semi-structured face-to-face interviews were used to examine the influence of riding on the identity construction of people with disabilities. The fifteen participants, three men and twelve women, were between fifteen and sixty-five years old and have various physical disabilities. The data analysis derives from identity theory, a social-psychological theory that understands identity as an inte...

The teaching process cannot be simplified to definitions of the best teachers as those possessing certain desirable teaching behaviours and skills (Katz, 2002). Although there are numerous factors that significantly influence learning and teaching, one might agree that specific teaching roles dominantly determine the quality of preschool teaching processes and learning outcomes. Furthermore, tw...

2016 will be marked as a year in which identity politics reached new levels of significance. Among numerous dramatic events, the UK referendum on membership of the European Union has brought many issues of interest to archaeologists to the fore. These range from entirely contemporary concerns such as the future of research funding in Britain to topics of more longitudinal significance, includin...

The impact of a major life transition on identity change is examined in this longitudinal study. Drawing on a framework provided by symbolic interactionism and identity theory (Stryker, 1968, 1987), we examined global self-esteem, interactional commitment and the identity hierarchies of a group of students while they were in secondary school and, again one year later, when they had made the tra...

Identity theft is often perceived as one of the major upcoming threats in crime. However, there is no commonly accepted definition of ‘identity theft’ or ‘identity fraud’, and it is impossible to study the real threat of this phenomenon without conceptual clarity. In this article, we attempt to provide a starting point for policy and research by proposing some definitions. We indicate that what...
