Web-based learning environments provide an attractive method for information dissemination, but in many instances they can be just electronic equivalents of printed course materials. Appropriate learning objectives and pedgagogical strategies are minimal or non-existent. Too often web-based learning environments lack cooperative and collaborative activities with the unintended consequence of fe...

This paper discusses and illustrates work in progress on the MEMO workbench for early model-based usability evaluation of interface designs. Characteristic features of the workbench include (a) the prediction of errors via rules that refer to user attributes; and (b) the automatic generation of methods for performing specific tasks and for recovering from errors.

Collaboration between IT staff and user groups is an enduringly problematic aspect of IS deployment and use in organizations. In this paper we offer an explanation as to why such difficulties persist despite management initiatives designed to eliminate them. We examine how a retail banking organization attempted to improve IT-user collaboration through the creation of an intermediary role calle...

Sexual assault generates much attention in social research, but male victims are largely neglected by a predominantly feminist perspective that seeks to highlight the gendered nature of sexual assault as a social phenomenon. As a result there is a relative lack of empirical information on male rape; but it is possible to chart the theoretical development of male rape as a social problem as it e...

If low-energy supersymmetry is realized in nature, the apparent discovery of a Higgs boson with mass around 125 GeV suggests a supersymmetric mass spectrum in the TeV or multi-TeV range. Multi-TeV scalar masses are a necessary component of supersymmetric models with pure gravity mediation or in any model with strong moduli stabilization. Here, we show that full scalar mass universality remains ...

The popular view of navigation is that it is a conscious, goal directed activity i n which someone is trying to reach a destination. Such a view of navigation i s essentially individualistic, objectivist and cognitive. Just as Lynch's aim i n trying to specify the basic, discrete units of (urban) space have had a significant impact on urban planning and design, so the metaphorical use of the co...

A decade ago, a national conference of macroeconomic educators called for fundamental reform in the teaching of intermediate macroeconomics, urging instructors to employ a single analytic framework rather than ‘responding to the fragmentation of macroeconomics by teaching a separate model for each school of thought’ (Erekson, Raynold and Salemi, 1996; Salemi and Siegfried, 1999). This paper des...
