Plagiarism as a clear example of academic corruption violates research ethics and slows down the production of science. Despite the criminalization of plagiarism in the Law on the Protection of the Rights of Authors, Writers and Artists, the quantitative nature of research in Iran has led to the growth of this behavior. Due to the importance of the discussion, this study aimed to investigate the relationship between the control source and research ethics in the prevention of plagiarism. The statistical population of the study is all members of the group and the Telegram channel of the School of Criminal Sciences as experts in Iranian criminal law, of which 212 people were selected as the final volume using the Cochran's formula. The data collection tool is the Ratter Control Source Questionnaire in which internal and external controls are checked. Also regarding research ethics and plagiarism, a researcher-made questionnaire design and their face and content validity using the opinions of three experts confirmed and their reliability for research ethics and plagiarism questionnaires with Cronbach's alpha coefficient of 0.82 and 0.87 was calculated .According to the findings, there is no relationship between internal and external control and prevention of plagiarism. Given that external control is used to justify unsuccessful behaviors and that not committing a crime is a successful behavior, the lack of a link between external control and plagiarism prevention is justified, but the lack of a link between internal control and plagiarism prevention suggests that self-control and morality have no role in preventing plagiarism. Thus, it can be said that the criminalization of plagiarism and the development of intelligent plagiarism detection software such as the software of Iranian Research Institute for Information Science and Technology by increasing the costs of crime has led to deterrence. The findings also show that the variables of research ethics, age, academic status and employment status have a significant positive relationship with the prevention of plagiarism. This means that crime prevention is better guaranteed by increasing the age, improve academic standing and promote research ethics. However, studies show that gender has a significant negative relationship with the prevention of plagiarism. This means that women are more talented and willing to commit crimes. Findings from stepwise regression analysis also proved that among the five main variables, three factors of research ethics, academic status and gender are able to estimate crime prevention

The purpose of this study is to conduct a meta-study (including trans-theoretical, meta-analysis and meta-analysis) on research on factors affecting the prevention of theft during the years 85-96 in the metropolis of Tehran. Eighteen studies in the field of theft prevention through internet search in domestic databases and manual search in organizations and universities in Tehran, were identified and related information was analyzed. In order to collect data, a checklist was compiled based on the existing theoretical foundations and the data were collected using it. The results of meta-theory and meta-method showed that the researchers conducted in the field of research subject (except in the cases of analytical model extracted from the theoretical framework and background study, preliminary test of measuring device, operational definition, measurement of reliability and validity, mentioning limitations and obstacles of research and ethical considerations ) And also the results of the meta-analysis showed that the size index of the combined effect of r in the field of factors affecting the prevention of theft in the fixed model was 0.695 and in the random model was 0.636, which according to Cohenchr('39')s criterion was considerable. But in a separate study, in the field of factors affecting the prevention of theft, the effect of the category of disciplinary factors was more than the categories related to security and socio-cultural factors. The results of Egger regression test, N-error-free test, dual and tweedy correction and fitting test and funnel diagram showed no diffusion bias in the meta-analysis sample. Due to the heterogeneity in the studies, the moderators were analyzed, which indicates the modulating effect of the research sampling method in the field of factors affecting the prevention of theft.

Designing electricity distribution networks, stealing it, increasing the price of metals, especially copper metal, is one of the common crimes. The purpose of the research is to identify the effective factors in preventing the occurrence of electrical equipment theft crimes. The research is applied in terms of its descriptive and analytical method, and in terms of the nature of the qualitative data and the non-probability sampling method of the snowball type, the statistical population is 22 experts in the field of theft prevention and for the purpose of interview analysis. Open, axial and selective coding and semi-structured interview tool were used in the letter.In situational prevention, increasing effort by 34% is in the first place, increasing the risk of crime by 26% in the second place, and removing excuses for theft by 20% are in the third place. Electrical equipment and strengthening social activists in the prevention of theft of electrical equipment each with 26% in the first place and the concept of needs management with 22% in the second place and in police prevention, increasing the speed of information about the theft of electrical equipment with 28% in the first place, increasing the speed of police presence at the scene of theft Electrical equipment is in second place with 24% and increasing the speed of action and being close to people to discover and identify thieves of electrical equipment is in third place with 20%.
