This paper reviews quantitative literature that addresses the questions of what explains why people buy virtual goods. The study reviews independent and dependent variables, path coefficients, used methodologies, theoretical backgrounds as well as types of services covered in the relevant literature. The goal of the paper is both to provide an overview to the literature and to investigate reasons...
The authors conducted a meta-analysis about the relationship between Information Technology (IT) capability and business performance which aggregates empirical findings from the information technology literature. This paper confirms that IT capability has significant impact on business performance. Our research also finds that different types of IT capability measurement, different types of performance...
As robots become increasingly capable and autonomous, the role of a human operator may be to supervise multiple robots and intervene to handle problems and provide strategic guidance. In such cases, the extent to which HRI tools support the human supervisor's situational awareness (SA) and ability to intervene in an appropriate and timely fashion will constrain the scale of operations (e.g., the number...
Stata is a comprehensive statistical package. This manuscript together with an example illustrated Stata11.0 procedures and corresponding results in meta- analysis. The outcomes showed that Stata was powerful and personalized and convenient in meta-analysis. At present, there is still lack of strong evidence to support the clinical effect on eradicating helicobacter pylori in chronic gastritis patients...
Genome Wide Association Studies (GWAS) are developed to find direct or indirect relations from given genomic configurations to physical characteristics or specific diseases. In order to build new GWAS, avoiding the complexities of field based studies, a statistical technique called meta-analysis can be used. Bad or unknown data quality has been largely identified as a major problem in meta-analysis...

To evaluate cytokine network of pulmonary fibrosis. A systematic literature search of EMBASE, MEDLINE, Cochrane Library was conducted through December 2007. Then potential regulatory pathway of cytokines was analyzed with a cubic spline intepolation and a linear differential model. The cytokines of silicosis fibrosis tissue were identified by meta-analysis. The related cytokines participated pulmonary...
In analyzing the reliability of complex systems, several types of data from full-system tests to component level tests are commonly available and are used. After a preliminary analysis, additional resources may be available and we wish to identify the best new data to collect to maximally improve the prediction of system reliability. In this paper we present methodology for selection of an appropriate...
