The present study was intended to identify the effect of a CAI web site for swimming to elementary school children’s learning motives and learning strategy. Fifth-grade children participated in this study. Subjects were classified into two groups that learned with the CAI web site throughout the swimming class and a control group that merely participated in the ordinary swimming class inside th...

Web site usability and accessibility continues to be a pressing problem. Hence, there are over 30 automated evaluation tools to help designers to improve their sites. Unfortunately, there is little evidence about whether these tools actually improve sites from both the designer’s and the user’s perspectives. To gain insight, we conducted what we believe to be the first study of automated web si...

introduction surgical site infection is a common side effect of surgeries that causes an increase in morbidity, mortality , patient length of stay in the hospital and hospital expenses. quality management as an organizational strategy helps improve working processes and enhance hospital productivity. method this study aimed to examine the impact of applying a quality management technique on red...

This article reports a content analysis of the privacy policy statements (PPSs) from 97 general reference health Web sites that was conducted to examine the ways in which visitors' privacy is constructed by health organizations. PPSs are formal documents created by the Web site owner to describe how information regarding site visitors and their behavior is collected and used. The results show t...

Mammalian expression systems, due to their capacity in post-translational modification, are preferred systems for biopharmaceutical protein production. Several recombinant protein systems have been introduced to the market, most of which are under clinical development. In spite of significant improvements such as cell line engineering, introducing novel expression methods, gene silencing and pr...

agriculture.unl.edu/ RESOURCES Precision farming is an emerging agricultural technology that involves managing each crop input on a site-specific basis to reduce waste, increase profits, and maintain the quality of the environment. Remote sensing is a technology that can be used to obtain various spatial layers of information about soil and crop conditions. It allows detection and/or characteri...

The greatest constraint to potato production in the United Kingdom (UK) is damage by the potato cyst nematodes (PCN) Globodera pallida and G. rostochiensis. Management of PCN depends heavily on nematicides, which are costly. Of all the inputs in UK agriculture, nematicides offer the largest potential cost savings from spatially variable application, and these savings would be accompanied by env...

Recent advances in precision agriculture technologies and spatial statistics allow realistic, site-specific estimation of nematode damage to field crops and provide a platform for the site-specific delivery of nematicides within individual fields. This paper reviews the spatial statistical techniques that model correlations among neighboring observations and develop a spatial economic analysis ...
