PROMOTING SCHOLARSHIP THROUGH DESIGN

How can new media positively transform scholarly practices? One possible way is for scholarly archives such as e-journals and digital libraries to better support the needs and practices of their users, instead of the publishing process. This article examines what it might mean to promote cognitive and social aspects of 'scholarship' through innovative archive design. Design requirements for supporting both scholarly tasks and scholarly communities are derived by analysing existing cognitive and social theories. A theoretical framework for guiding archive design is introduced: the contextually enriched document framework. This framework suggests that: document interfaces should enable practitioners to progressively enrich documents with important contextual information arising from social processes; and archive managers should engage in proactive practices to facilitate use and assist practitioners in realizing the benefits of the new technology. Both the design requirements and the framework are illustrated with examples from an existing electronic journal - The Journal of Interactive Media in Education .

Grandmothers Who Are Caregivers: An Overlooked Population

This paper examines the concerns of 22 African American grandmothers who are primary caregivers of their grandchildren. In-depth interviews were conducted and revealed that these grandmothers incurred economic hardships, marital difficulties, lifestyle changes, and stressors associated with multiple roles. Overall, however, these grandmothers reported that they enjoyed taking care of their grandchildren because it put meaning back into their lives. Implications for further research and the development of social service programs for African-American grandmothers who are caregivers and have multiple roles are discussed.     

‘Spite effects’ in tax evasion experiments

This paper sets out to consider individuals’ motivations to evade taxation. Experimental results indicate that individuals do not simply maximize pecuniary welfare. Their behaviour is consistent with the presence of a ‘spite effect’ when their perceptions are that enforcement variables are ‘excessive’.     

A framework for production control in health care organizations

The paper presents a hierarchical framework for production control of hospitals which deals with the balance between service and efficiency, at all levels of planning and control. The framework is based on an analysis of the design requirements for hospital production control systems. These design requirements are translated into the control functions at different levels of planning required for hospital production control. The framework consists of five levels of planning and control: patient planning and control, patient group planning and control, resources planning and control, patient volumes planning and control and strategic planning, though this last level does not make part of production control as such. Each of the levels of the framework is further elaborated in terms of the decisions made regarding patient flows and resources, and the co-ordination of the different planning levels. Implications of the framework are discussed by describing some points where current practice deviates from assumptions made in our approach. Recommendations for future research and development of the planning framework are formulated.     

Markov models of mite movements

Continuous time Markov models were used to analyse data from two bioassays to investigate the influence of β-fraction, a by-product of hop processing, on the two-spotted spider mite. The models were fitted to aggregate counts of the numbers of live and dead mites on treated and untreated halves of discs cut from leaves of hop and French bean plants. Some of the rate parameters were time dependent. Although not all parameters could be estimated precisely, the analysis enabled the quantitative effects of treatment over time to be estimated with reasonable precision. The estimated treatment effects were largely insensitive to the assumed values of other parameters. The first bioassay showed a progressive initial response to increasing concentration of β-fraction, although data at the intermediate concentration appeared anomalous. The second bioassay showed similar responses on hop and French bean leaves, with a stronger repellent effect on the lower leaf surface than on the upper surface.
