Nowadays, the world's scientific community has been publishing an enormous number of papers in different scientific fields. In such environment, it is essential to know which databases are equally efficient and objective for literature searches. It seems that two most extensive databases are Web of Science and Scopus. Besides searching the literature, these two databases used to rank journals in terms of their productivity and the total citations received to indicate the journals impact, prestige or influence. This article attempts to provide a comprehensive comparison of these databases to answer frequent questions which researchers ask, such as: How Web of Science and Scopus are different? In which aspects these two databases are similar? Or, if the researchers are forced to choose one of them, which one should they prefer? For answering these questions, these two databases will be compared based on their qualitative and quantitative characteristics.

Abstract-Reporting detected errors is an important ethical behaviour of auditors which is one dimension of the quality of auditors' work. The main objective of this study is to investigate the effects of auditors' individual characteristics including personality type and locus of control on auditors' intention to report errors. Data are collected by distributing 1000 mail questionnaires among senior auditors in Malaysia. Applying multiple regression analysis, the results reveal that there is a significant and positive relationship between auditors' individual characteristics and their intention to report errors. In fact, research findings indicate that auditors with personality type A and internal locus of control have more intention to report errors than auditors with type B and external locus of control.

Journal impact factor (IF) as a gauge of influence and impact of a particular journal comparing with other journals in the same area of research, reports the mean number of citations to the published articles in particular journal. Although, IF attracts more attention and being used more frequently than other measures, it has been subjected to criticisms, which overcome the advantages of IF. Critically, extensive use of IF may result in destroying editorial and researchers' behaviour, which could compromise the quality of scientific articles. Therefore, it is the time of the timeliness and importance of a new invention of journal ranking techniques beyond the journal impact factor.

This study examines the effect of capital structure and ownership structure on Firm's performance using sample of 123 companies listed on Tehran Stock Exchange (TSE) during eight-year period, 2001-2008. We adopt rate of return on assets as a measure of firm's performance. The research results show that capital structure and ownership structure have a positive impact on the performance of companies listed on TSE. This study indicates consistency with prior empirical researches and also all research subsidiary hypotheses are consistent with the theoretical assumptions and all of them have been approved.
