Inspired by our exploration of the applicability of automated question answering (QA) technology to the task of business intelligence and general design science principle, we advocate a meta approach to the QA (fact seeking) applications since it does not rely on a single system and may provide the necessary accuracy and responsiveness. We present our prototype of a fact seeking meta engine, th...

BACKGROUND Indirect treatment comparison (ITC) and mixed treatment comparisons (MTC) have been increasingly used in network meta-analyses. This simulation study comprehensively investigated statistical properties and performances of commonly used ITC and MTC methods, including simple ITC (the Bucher method), frequentist and Bayesian MTC methods. METHODS A simple network of three sets of two-a...

studying the effect of marketing tactical capabilities on the financial performance of the firms is now proposed as one of the most important priorities of marketing researches. however, the results of the studies in many academic fields that are conducted about a specific issue are usually contrasting. meta-analysis is a research approach that helps the researcher to achieve a suitable combina...

Range restriction in most data sets is indirect, but the meta-analysis methods used to date have applied the correction for direct range restriction to data in which range restriction is indirect. The authors show that this results in substantial undercorrections for the effects of range restriction, and they present meta-analysis methods for making accurate corrections when range restriction i...

Visuo-spatial skills are believed to be enhanced in autism spectrum disorders (ASDs). This meta-analysis tests the current state of evidence for Figure Disembedding, Block Design, Mental Rotation and Navon tasks in ASD and neurotypicals. Block Design (d = 0.32) and Figure Disembedding (d = 0.26) showed superior performance for ASD with large heterogeneity that is unaccounted for. No clear diffe...

the present study examined the effect of grouped meta-cognitive therapy on meta-cognitive beliefs of patients' suffering from generalized anxiety disorder. this research is a quasi-experimental with pre-test and post-test design with control group in which two groups of experiment and control are used. the present study population includes all state universities, islamic azad universities ...

In regression applications, there is no single algorithm which performs well with all data since the performance of an algorithm depends on the dataset used. In practice, different algorithms / approaches are tried, and the best one is selected in each application. It is meaningful to ask whether there is a different way instead of running such tedious experiments. In meta learning studies, one...

For over a century, psychologists have investigated the mental processes of expert performers - people who display exceptional knowledge and/or skills in specific fields of human achievement. Since the 1960s, expertise researchers have made considerable progress in understanding the cognitive and neural mechanisms that underlie such exceptional performance. Whereas the first modern studies of e...

This systematic review and meta-analysis investigates the impact of cognitive training and general mental stimulation on the cognitive and everyday functioning of older adults without known cognitive impairment. We examine transfer and maintenance of intervention effects, and the impact of training in group versus individual settings. Thirty-one randomised controlled trials were included, with ...

the present study examined the effect of grouped meta-cognitive therapy on meta-cognitive beliefs of patients' anxieties suffering from generalized anxiety disorder. this research is a quasi-experimental with pre-test and post-test design with control group in which two groups of experiment and control are used. the present study population includes all state universities, islamic azad uni...
