Background. A multidimensional, brief, and flexible stroke-specific health-related quality of life (HRQOL) measure is still needed. The aim was to develop a shortened version of the HRQOLISP-102, a multiculturally generated measure with excellent psychometric properties. Methods. Participants included 100 (Ibadan, Nigeria) and 103 (Berlin, Germany) stroke patients compared to 100 (Ibadan) and 5...

BACKGROUND The SF-36 is one of the most widely used self-completion measures of health status. The inclusion of the SF-36 in the first Australian national household panel survey, the Household, Income and Labour Dynamics in Australia (HILDA) Survey, provides an opportunity to investigate health inequalities. In this analysis we establish the psychometric properties and criterion validity of the...

This study examined the effect of the incorporation of environmental distractors in computerized continuous performance test (CPT) on the ability of the test in distinguishing ADHD from non-ADHD children. It was hypothesized that children with ADHD would display more distractibility than controls while performing CPT as measured by omission errors in the presence of pure visual, pure auditory, ...

However, little attention has been paid to address philosophical and methodological issues and to provide scientific rationales of marketing-finance. Therefore, the authors strive to address several philosophical and methodological issues in the marketing-finance interface...

Rather than using text for scientific research reports, we have proposed developing highly-structured reports with rich semantic models. In this paper, we consider detailed structures for the components of research reports using a modeling framework based on a rigorous upper ontology. For instance, we consider the use of structured descriptions of Research Designs to support evaluation of inter...

This paper reports the validation scores of the Student Tool for Technology Literacy (ST2L), a performance-based assessment based on the National Educational Technology Standards for Students (NETS*S) used to measure middle grade students Information and Communication Technology (ICT) Literacy. Middle grade students (N 1⁄4 5884) from school districts across the state of Florida were recruited f...

Despite the fact that both the Efficient Market Hypothesis and Random Walk Theory postulate that it is impossible to predict future stock prices based on currently available information, recent advances in empirical research have been proving the opposite by achieving what seems to be better than random prediction performance. We discuss some of the (dis)advantages of the most widely used perfo...

The purpose of this study is to contribute to efforts to improve methods for gathering and analyzing data from classroom observations in early literacy. The methodological approach addresses current problems of reliability and validity of classroom observations by taking into account differences in teachers’ uses of instructional actions (e.g., modeling) in specific skill areas (e.g., fluency, ...

Web surveys have become a very important way of empirical research. The rise of social media provides a new platform for web surveys. Investigators can collect data based on different social media platforms to get more respondents of higher external validity at a lower cost. However, there is no domestic expert and scholar to conduct related researches on web surveys based on social media. This...
