Survey tools are widely used within Child Computer Interaction however the validity and reliability of children’s responses are often brought into question. This paper reports on a study on the effects of asking the same questions to the same children over a period of a week to ascertain the validity of children’s responses when completing a single questionnaire. The results showed that over 50...

Arrival performance for the United States shows that over 83 percent of flights are actually on time. However, 17 percent delayed flights are still an indisputable high number, having almost eight million commercial travel flights per year, only in the US. Knowledge of the conditions leading to flight delays may be used in a monitoring and prediction tool to diminish its impact on commercial fl...

STUDY OBJECTIVE To explore the impact of de-industrialisation over a 20 year period on working conditions and health among sawmill workers, in the province of British Columbia (BC), Canada. DESIGN AND SETTING This investigation is based on a sample of 3000 sawmill workers employed in 1979 (a year before the beginning de-industrialisation) and interviewed in 1998. The sample was obtained by ra...

In recent years, the threats to the integrity of science posed by the dishonesty of a small minority of scientists, and the biases held by most scientists, have become a topic of lively discussion. We believe that faulty measurement of biochem ical compounds is sufficiently common that it also serves to undermine the integrity and efficiency of science. We approach this neglected area by first ...

This paper reports on two case studies, the Information and Communications Technology (ICT) adoption among small businesses conducted in both United States and China. One small business from Nebraska (United States of America) and one small business from Sichuan (China) were chosen for comparison. The purpose of this paper is to conduct a comparative case study based on the ICT adoption among s...

Auxetic behavior in low porosity metallic structures is demonstrated via a simple system of orthogonal elliptical voids. In this minimal 2D system, the Poisson's ratio can be effectively controlled by changing the aspect ratio of the voids. In this way, large negative values of Poisson's ratio can be achieved, indicating an effective strategy for designing auxetic structures with desired porosity.

The strength of Ultra-High Performance Concrete (UHPC) can be sensitively affected by the curing method used. However, in contrast to the precast plant production of UHPC where a standard high-temperature steam curing is available, an optimum curing condition is rarely realized with cast-in-place UHPC. Therefore, the trend of the compressive strength development of UHPC was experimentally inves...

BACKGROUND The accurate recording of findings in clinical medicolegal cases is important, yet the current J88 form used for this purpose in South Africa has been reported to have many flaws. In addition, there are reports of poor completion of the form, which could in part be due to its poor design and clarity. OBJECTIVE To describe the process that was undertaken to revise the current J88 fo...

Developing the written communication skills of engineering students has become a higher priority learning outcome since the advent of the ABET EC2000 criteria. Increased numbers of writing intensive courses, refinements to document requirements and proliferation of rubric development indicate the effort used to address the elevated priority. The sharing of rubrics and standards for the formatti...
