One of the most important research topics in HRM field of study in recent decades, is the study of HRM-performance relationship. The importance of these studies is so much, as they imply both micro and macro implications of HR practices, encompass HRM influences on performance outcomes, and also the existence reason of HR practices and the nature of its practices. However, a body of researches have scientifically criticized/questioned the findings of aforementioned previous studies. These criticisms often comprise the methodological aspects of previous studies. Current study, in two phases, has been done by considering the importance of prementioned issue and the lack of a study in order to introduce and summarize those criticisms. First, we applied “mixed research synthesis” approach as one of the subsidiaries of meta-synthesis method. By studying and summarizing 40 valid critical papers in this field of study, we have presented and explained a five-dimensioned guiding map for introducing the criticisms on the HRM-performance researches. In order to assess research validity, CASP standard checklist was applied, and to determine the reliability, Cohen's Kappa was used in SPSS software which was confirmed by resulting in 0/762.  In the second phase, the five dimensions, found in the former phase, were prioritized with AHP method.

In recent decades, information technology, especially with all aspects of our life and professional career has been stirred. Because IT applications in different fields and the rapid growth of computers in organizations, to review the level of acceptance and rejection of information technology in organizations have special significance. Hand with the growth of research in various fields related to the IT acceptance and dealing with a scattering of information and information explosion, control over all aspects of this area is largely impossible. Therefore, the combination of research studies conducted in this matter to extract the systematic and scientific results for researchers is very important. In this study using meta-analysis methods with comprehensive meta-analysis (CMA) software, for examining a large number of theses, articles and researches done in connection with the adoption of information technology in Iran, 19 studies with 21 hypotheses and variables have been selected. The results of meta-analysis shows that employee empowerment, extent of use of technology, perceived ease of use and perceived usefulness of IT had the most influence on the acceptance of information technology in the Iranians organizations.
