This paper examines the challenges that 'grass roots' e-learning initiatives face in trying to become sustainable. A cross-institutional study focused on local, rather than centrally driven, initiatives. A number of successful e-learning innovations were identified that had been driven by capable teachers seeking solutions to real educational problems. However, most of these remain in a high-risk category for institutions and offer poor rewards to their creators. While they may attract grant funding, these initiatives are typically not well supported in other important ways. Semi-structured interviews were conducted with 30 staff in various academic and support roles from the tertiary sector in New Zealand, who were nationally recognised as e-learning leaders. Analysis of their responses revealed both institutional and cultural barriers to long-term sustainability. The following influences on sustainability were identified and discussed: supportive organisational structures, a vision shared by all and staff accountability. The paper proposes that not all initiatives are sustainable and offer practical strategies for achieving diffusion and continuity through collective action. The paper concludes that there is a need for cross-functional collaboration to accommodate different and sometimes conflicting perspectives. This is just one aspect of the culture change that research shows is needed for e-learning to transform, rather than sit uncomfortably alongside, institutional practice.
SUMMARYUpper bound techniques are used to analyse the stability of slopes of material failing according to a nonlinear failure criterion, such as closely jointed rocks. The global, extremal nature of upper bound calculations is discussed, as is the inverse use of such procedures for obtaining safe lower bound estimates for material strength properties in back analyses. Specific results are presented for the material model proposed by Hoek and Brown.
A significant increase in the use of computer-supported learning (CSL) within schools and universities across the world gives rise to concern about gender-related differences in performance and interaction style in these environments. Research has shown that initial perceptions of CSL environments as democratic and offering equal opportunities to all students were flawed because interactions that take place through electronic channels lose none of the socio-cultural complexity or gender imbalance that exists within society. Much of the recent literature states that women are disadvantaged because of inferior levels of access and technology literacy and dominant male behavior. However, the assumption that difference implies disadvantage is challenged by evidence that variable factors such as professed confidence and apparently dominant interaction styles do not necessarily lead to better educational opportunity and performance. This paper contains a summary of gender-related issues identified by international research and academic practice together with supportive case study examples. The conclusion is that women often perform better than men despite the observable differences in interaction style.

Contemporary research identifies significant gender-related differences in performance and interaction style in computer-supported learning (CSL) environments. Evidence suggests that initial perceptions of these environments as democratic and offering equal opportunities to all students were flawed because interactions that take place through electronic channels lose none of the sociocultural complexity or gender imbalance that already exists within society. This paper presents a summary of gender-related issues identified by international research and academic practice together with the opinions expressed by participants in a discussion forum staged at ALT-C in 2001. Two main questions were addressed during the conference forum. Firstly, if computer access and literacy levels are assumed to be equalizing as the literature suggests, how can educational designers using CSL technologies best serve all student groups? Secondly, does the existence of gender-based differences in behaviour and interaction style in CSL environments mean that any student group is disadvantaged? The paper concludes with suggestions about how educational designers might increase the flexibility of CSL courses to offer equal opportunities to all students. A number of issues for further research are also identified
