Hypotheses concerning the effects of sex and class On future orientation were tested on 100 boys and girls between the ages of 14 and 16. Future orientation was measured in various domains of life, constituting either private or public areas of concern (e.g., family, environment), on the dimensions of density (number oi hopes and fears voiced by the subject), extension, and optimismpessimism. A...

This paper investigates the relevance of government purchasing behavior for innovationbased economic growth. We construct a parsimonious Schumpeterian growth model in which demand from the public sphere can effectively alter the economy’s rate of technological change. We incorporate results of various empirical studies arguing that public sector demand acts as incentive for private innovation a...

The purpose of this replication and extension study was to examine how teacher delivery and student progress influenced experienced teachers’ perceptions of overall teaching effectiveness. Participants (N = 60 experienced music teachers) viewed 12 private lesson excerpts that included four separate conditions: (a) high teacher delivery and more student progress, (b) high teacher delivery and le...

This paper presents three models which enable the customisation of Universal Description, Discovery and Integration (UDDI) query results, based on some pre-defined and/or real-time changing parameters. These proposed models detail the requirements, design and techniques which make ranking of Web service discovery results from a service registry possible. Our contribution is two fold: First, we ...

This paper studies the interaction between coordination and social learning in a dynamic regime change game. Social learning provides public information to which players overreact due to the coordination motive. So coordination affects the aggregation of private signals through players’ optimal choices. Such endogenous provision of public information results in inefficient herds with positive p...

Hierarchical identity-based encryption (HIBE) is an extension of identity-based encryption (IBE) where an identity of a user is organized as a hierarchical structure and a user can delegate the private key generation to another user. Providing a revocation mechanism for HIBE is highly necessary to keep a system securely. Revocable HIBE (RHIBE) is an HIBE scheme that can revoke a user’s private ...

Ubiquitous communication will be one of the paradigms for the next decades. Mobile communication systems experience tremendous growth rates, Internet access is integrated in vehicles, pedestrians use Internet-ready mobile phones. This use of the Internet demands for a highly reliable and secure system, especially when used in nonacademical environments like remote offices, e-commerce, or traffi...

The extension of privacy laws to cover private sector providers and the proposal of a National Health Privacy Code highlight the importance of examining privacy issues in aged care policy and practice. Although privacy in health and aged care may also include physical, psychological and social dimensions, it is informational privacy that is the focus of these recent changes. In this paper a ran...

Körner and Marton established the capacity region for the 2-receiver broadcast channel with degraded message sets. Recent results and conjectures suggest that a straightforward extension of the Körner-Marton region to more than 2 receivers is optimal. This paper shows that this is not the case. We establish the capacity region for a class of 3-receiver broadcast channels with 2-degraded message...

Partitioned Global Address Space (PGAS) languages offer an attractive, high-productivity programming model for programming large-scale parallel machines. PGAS languages, such as Unified Parallel C (UPC), combine the simplicity of shared-memory programming with the efficiency of the messagepassing paradigm by allowing users control over the data layout. PGAS languages distinguish between private...
