The fan and rays of the C. elegans male tail constitute a compound sensory organ essential for mating. Within this organ, the individual sensilla, known as rays, have unique identities. We show that ray identities are patterned by a selector gene mechanism in a manner similar to other serially homologous axial structures. One selector gene that promotes the identities of a subset of the rays is...

This article presents a model of social identity development and integration in the self. Classic intergroup theories (e.g., social identity theory, self-categorization theory) address the situational, short-term changes in social identities. Although these theories identify the contextual and environmental factors that explain situational changes in social identification, the intraindividual p...

We consider some parametrized classes of multiple sums first studied by Euler. Identities between meromorphic functions of one or more variables in many cases account for reduction formulae for these sums.  2005 Elsevier Inc. All rights reserved.

Research related to colonialism and post colonialism shows how the identities of indigenous people were constructed and how these identities are reconstructed in our contemporary world. The thrust of this paper is that colonialism brought a shift in the linguistic structure of Ghana with the introduction of the use of English among Ghanaians. The coexistence of both Ghanaian languages and Engli...

the key argument of this commentary is that patient choice has a broader meaning than suggested by consumerist choice models. in increasingly marketized health care systems with diversified and knowledge-based service arrangements, patients are continuously obliged to choose insurers, physicians or hospitals and treatments—whether they like it or not. however, health care users refer to a wide ...

The Dissociative Identity Disorder – Trait Mapper (DID-TM) is a system for use by clinicians and researchers in the treatment and study of dissociative disorders. In these disorders, individuals manifest multiple identities that must be understood and tracked through treatment. The system’s visual representations assist the user in gaining insight into the structures of personalities, patterns ...

We generalize the selective-ID security model for HIBE by introducing two new security models. Broadly speaking, both these models allow the adversary to commit to a set of identities and in the challenge phase choose any one of the previously committed identities. Two constructions of HIBE are presented which are secure in the two models. Further, we show that the HIBEs can be modified to obta...

A common, but important issue with large Information Technology (IT) organizations that implement Knowledge Management (KM) strategies is end-user apathy and indifference towards the KM initiative in organizational units. End-user communities associate themselves minimally with the organization-wide KM apparatus, rarely contributing to the initiative, or/and in a few cases completely dissociate...

Statistical agencies that disseminate data to the public are ethically and often legally required to protect the confidentiality of respondents’ identities and sensitive attributes. To satisfy these requirements, Rubin (1993), Little (1993), and Fienberg (1994) proposed that agencies utilize multiple imputation. For example, agencies can release the units originally surveyed with some values, s...
