Maximising resilience to sea-level rise in urban coastal ecosystems through systematic conservation planning
Coastal cities and their natural environments are vulnerable to the impacts of climate change, especially sea-level rise (SLR). Hard coastal defences play a key role in protecting at-risk urban coastal populations from flooding and erosion, but coastal ecosystems also play important roles in the overall sustainability and resilience of cities and urban centres by contributing to coastal protection. Conserving coastal ecosystems and maximising the…

Stuart Marshall’s Idiophonics
Artist, educator and film- and video-maker Stuart Marshall (1949–1993) was an important link between the American experimental music of the 1970s and the British visual arts scene of the same epoch. The author looks at one of Marshall’s works, Idiophonics (a.k.a. Heterophonics), and offers thoughts on the occasion of the 40th anniversary of its presentation in London and Newcastle in 1976

A Theoretical Integration of User Satisfaction and Technology Acceptance
In general, perceptions of information systems (IS) success have been investigated within two primary research streams—the user satisfaction literature and the technology acceptance literature. These two approaches have been developed in parallel and have not been reconciled or integrated. This paper develops an integrated research model that distinguishes beliefs and attitudes about the system (i.e., object-based beliefs and attitudes) from beli…
Understanding Information Technology Usage
The Technology Acceptance Model and two variations of the Theory of Planned Behavior were compared to assess which model best helps to understand usage of information technology. The models were compared using student data collected from 786 potential users of a computer resource center. Behavior data was based on monitoring 3,780 visits to the resource center over a 12-week period. Weighted least squares estimation revealed that all three models…
On the Use, Usefulness, and Ease of Use of Structural Equation Modeling in MIS Research
Structural equation modeling (SEM) using LISREL, EOS, PLS, or other second genration data analysis techniques is increasingly being applied in MIS research. These techniques are important because they provide powerful ways to address key IS research problems such as understanding IT usage. However, they may lead to inappropriate conclusions if statistical criteria are permitted to drive analysis and override substantive understanding of a problem…
Perceived Usefulness, Ease of Use, and Usage of Information Technology
This paper presents the findings of two studies that replicate previous work by Fred Davis on the subject of perceived usefulness, ease of use, and usage of information technology. The two studies focus on evaluating the psychometric properties of the ease of use and usefulness scales, while examining the relationship between ease of use, usefulness, and system usage. Study 1 provides a strong assessment of the convergent validity of the two scal…
Subjective Burden of Husbands and Wives as Caregivers
Investigated were changes over time for caregivers of dementia patients, with a focus on factors associated with nursing home placement. Caregivers were all spouses, and at the time of the initial interview were caring for the patient at home. Subsequent nursing home placement was more strongly associated with subjective factors, particularly caregivers' perceived burden, than with objective indicators of the severity of dementia. Although wives …

Subjective Burden of Husbands and Wives as Caregivers
