This paper examines the application and implementation of a computer-based information system designed to record, store, retrieve and analyse archaeological site data for the Brighton area based upon techniques currently being developed in the field of Geographic Information Systems (GIS). The paper discusses the need for spatial data handling capabilities in archaeology at the regional level t...

Poorly designed Web sites can lead to lost productivity and revenue. The question of how to improve the design of informational Web sites is thus of critical importance. Although most prominent Web sites are created by professional design firms, many smaller sites are built by people with little design experience or training. As a consequence, Web sites with local reach, such as those belonging...

Unless a web site meets the needs of the intended users it will not meet the needs of the organisation providing the web site. Web site development should be user-centred, evaluating the evolving design against user requirements. The first step is to define the business objectives, the intended context of use and key scenarios of use. This helps prioritise design and provides a focus for evalua...

P erformance and high availability are critical at Web sites that receive large numbers of requests. This article presents several techniques—including redundant hardware, load balancing, Web server acceleration, and efficient management of dynamic data—that can be used at popular sites to improve performance and availability. We describe how we deployed several of these techniques at the offic...

Analytical chemistry methods can be classified as “definitive methods” or “screening methods.” Environmental decision-makers and practitioners frequently make a simplifying assumption that definitive analytical methods generate “definitive data,” while screening methods generate “screening data.” The pervasiveness of this incorrect assumption inhibits the development and application of more cos...

Web site design and construction is characterised by the use of a number of poorly integrated technologies – mark-up languages, databases, server side middleware, client side scripting languages, etc. The absence of an integrated structure means that reusability and site maintenance are difficult to achieve. Instead of this, we are building a component-based declarative web site design system, ...

W eb caching is widely viewed as an effective way to improve Internet performance. Web cache servers temporarily store Web documents. Because cache servers are typically located near the clients, using them reduces retrieval latencies and the number of requests reaching Web servers, thus reducing overall network activity. Most Web cache servers make cache decisions based on document names or UR...

Web sites often provide the first impression of an organization. For many organizations, web sites are crucial to ensure sales or to procure services within. When a person opens a web site, the first impression is probably made in a few seconds, and the user will either stay or move on to the next site on the basis of many factors. One of the factors that may influence users to stay or go is th...

OBJECTIVE Characterization of a non-invasive method of quantifying subepidermal moisture (SEM) surrounding stages III and IV pressure ulcers (PrUs) in spinal cord injury (SCI). DESIGN Prospective, single-visit, single-rater, observational study, using repeated-measures analysis. Method Setting-inpatient units of one VA SCI Center. PARTICIPANTS Convenience sample of 16 subjects with SCI with...
