The knowledge related to the methodology of the field trial study as a type of intervention studies, yet for many of our researchers is not fully understood. The aim of the current study was a better understanding of conducting this type of research. Field trial studies are done on healthy individuals and aim to prevent. These types of studies such as clinical trials are performed on both individual and collective levels. One type of these studies is Community Intervention Trial which is usually done on a large scale population. Field trial study should be carried out in stages, such as the formulation of hypotheses, selection of the population (reference population, study population, and sampling), measuring the baseline variables (before conducting preventive intervention), random allocation of subjects to intervention and control groups, doing interventions and measuring outcome. The methodology of field trial studies is very similar to clinical trials. The difference is that field trials are conducted on healthy individuals and aim to prevent and also the sample size required to this type of study is relatively more, and these studies are usually time consuming and costly.

Background Scientific articles represent the efforts of researchers and are useful and valuable source of information and can be taken as a basis for scientific and performance analysis. The purpose of this research is to study the scientific production of the subject area of ethics in accounting. Method This descriptive-analytical research examined 145 articles of the subject area of ethics in accounting from 1984 to 2018. The research data were collected using a check list tool and statistical analyzed by using Excel software. Data was analyzed by descriptive statistics such as data classification based on frequency distribution and mean, tables and charts drawing. Results The research findings show that in 145 published articles, 318 authors participated. Among the educational and research centers, the Islamic Azad University, Science and Research Branch, with 17 articles ranked first. Most topic orientation, professional ethics with 21 articles in first rank and from total of 3, 288 references cited in the articles, approximately 72% of the references were in English and 28% in Persian. Conclusion Considering the importance of the issue, little number of scientific productions related to ethics in accounting and consequently, the lack of relevant scientific resources in the country, emphasizes the need for more attention in this area.

Background and aim: With increasing competition in the scientific society, attention to the quality of journals has enhanced and different methods are used to evaluate the journals. Therefore, the aim of this study was to find a comprehensive view on the status of the performance of the valid journals in the field of accounting and finance in Iran by gathering different evaluation criteria. Material and methods: This evaluative study was conducted using a scientometric method. Evaluation criteria consisting 14 components were prepared based on studies performed in this field, data on various components were collected by referring to the website of the journals and databases, and finally, these data were analyzed using Excel. The statistical population was 18 and 9 accounting and financial journals, respectively. Findings: The findings showed that 66. 6% of journals were published by State universities and 33. 4% by other centers. According to the State Journal database, 3 journals were ranked A and the others B and C. No journal was ranked A+. The mean of immediacy index and impact factor were 0. 018 and 0. 253 in the accounting journals and 0. 015 and 0. 123 in the financial journals, respectively. Only one journal was indexed in 6 national and 4 international databases. Totally, 18% of the journals were indexed in 80% of these databases and the others in lower ranks. In summary, two journals of "Financial Accounting Research" and "Financial Knowledge of Securities Analysis" were ranked first in this field. Conclusion: Averagely, accounting journals have higher impact factor and cumulative citations compared with financial ones. It is necessary to pay attention to the quality of articles in financial journals and indexing in valid databases in accounting journals.

Considering the importance of evaluating scientific output in different scientific field with scientometric indicators, this study aimed at analyzing and visualizing the scientific maps of research on the accounting field in Iran during a decade (2010-2019). For this, the output on the field in the form of published papers in 15 Irania research journals indexed in Islamic Scientific Citation (ISC) database were analyzed by scientometric and scientific mapping software packages. Based on the findings, top 20 authors authored about 30% of all papers. The mean rate of citation per paper was 2.65. The rates of authors' centrality showed authors' faire scientific interactions and connections. The main authorship pattern was multi-authored (mostly two-authored) one. The highly-frequent keywords were earning management, audit quality, and stock return, respectively. The highly-frequent co-occurred keyword pairs were earning quality-discretionary accruals, operating cash flow-accruals, unconditional conservatism-conditional conservatism, respectively.
