The purpose of the present research is to create and validate a tool for the evaluation of the joint police exercise that is appropriate to the characteristics and local culture of the education

The method of the current research is a descriptive survey type. The community of this research was all the experts, professors, commanders, managers, and those involved in the design and implementation of the exercises of the University of Police Sciences and the experts of the Naja and Fateb operations deputy, 75 of whom were selected as a snowball. The data collection tool was a researcher-made questionnaire, the validity of the questionnaire was confirmed by experts, and Cronbach's alpha coefficient for the underlying factors was 87%, 94%, and 86%, respectively. In terms of data analysis and construction of the desired tool, confirmatory factor analysis method with PLS software and content validity (CVR) and (CVI) have been used.

The final instrument of this research has 104 items that include three factors before the exercise, during the exercise and after the exercise. The item reliability and composite reliability indicators indicate the appropriate reliability of the tool. In addition to exploratory and confirmatory factor analysis, convergent and discriminant validity results also showed that the instrument has acceptable validity.

The results have shown that this tool can be used to measure and evaluate the joint police exercise in the stages before, during and after the implementation of the joint police exercise in education and training system

Due to the growth of the global dimensions of drug trafficking, the destructive effects of this crime on Iran's economy and security, and the neglect of drug trafficking cases hidden in some of the money laundering issues raised in the Economic Security Police, have caused the writing of the present study with the aim of developing a model for the criminalization of drug trafficking through money laundering cases.

The present paper was applied research which was conducted with a qualitative approach in terms of purpose. The statistical population consisted of the money laundering cases which were under investigation by the Tehran Economic Security Police, and these cases were purposefully selected until the thirteenth case until the research reached to the theoretical and thematic saturation. Data were analyzed using MAXQDA software.

Nine categories included as, information sources, technical measures, defendants and related parties, officers, crime detection, departments and organizations, laws, banking network, banking operations, and finally, after selective coding, they were divided into organizational and non-organizational dimensions.

The proposed model in 2 dimensions, 9 components and 126 indicators can be used as a guide for the economic security police and the anti-narcotics police until its implementation and the development of a model for detecting drug trafficking crime via tracking money laundering cases in the fight against those offences which may provide an interactive and managerial approach between the above-mentioned two polices (economic security and the fight against narcotics). Hopefully by benefiting from the executive measures designed in the current model, practitioners may move from the path of crime detection in the fight against money laundering to the detection of drug trafficking and vice versa.

The purpose of this article is the pathology of crypto-currency crimes in cyberspace and it intends to use cyberspace data to express a new perspective for criminalizing virtual currencies. The current research is an applied research in terms of the type of research and a qualitative research in terms of the method of implementation and research method, with two qualitative methods of examining scientific documents and content analysis of virtual currencies. The data collection tools are scientific texts and interviews with experts and the statistical community of virtual currency experts. The research data were thematically analyzed and subjected to descriptive analysis. The findings of the research show that the three main categories of structure, decision-making and information are effective on the dependent variable of the research, i.e. the massing of virtual currencies.It is concluded that the most important indicators of the comprehensive system of criminalization of virtual currencies are the development of guidelines and guidelines for the criminalization of digital currencies, and there are traces of money laundering in cryptocurrencies and the identification of effective factors in cyberspace and criminalizing factors of virtual currencies in the research. It is clearly visible. These cases are one of the important factors of disorder and disturbance in economic security, and the failure to perform pathology in the field of virtual currencies, its economic consequences are irreparable, and the hidden crimes resulting from them lead to the reduction of the country's judicial and security system's control over crime in real and virtual space. will be Finally, one of the characteristics of the research is that it is possible to use solutions against illegal activities in this field.

improving the quality of shootings during the mission has always been the concern of Faraja officials. The purpose of this research is to investigate the effect of using Naptel simulators and laser pistols on improving the shooting skills of prevention police officers of Greater Tehran police command.

In terms of purpose, this research is practical and in terms of research method, it is a quasi-experimental research. The statistical population of the research includes 2000 Fateb prevention police employees and the sample size is 60 people, including two test groups of Naptel and laser pistol, in addition to the control group of each group, there are 20 people, and the sampling was done as available. The means of collecting information were library and field test and shooting test based on the standard forms determined in Faraja. The reliability of the instrument was calculated by the test-retest method with the correlation coefficient between the two tests and retests in the Naptel and laser pistol groups equal to 0.963 and 0.856, respectively. To analyze the data, multivariate covariance analysis was used by spss software.

The significance level of covariance analysis regarding the effect of training with laser pistol and Naptel simulator was less than 0.05, so with 95% confidence, there is a difference between the control and experimental groups in the scores of shooting speed and accuracy skills. Also, the average scores of both skills were higher in the laser pistol group than in the Naptel simulator group.

Training with a laser pistol and a Naptel simulator has a significant effect on improving the shooting skills, accuracy and speed of Fatab prevention police officers, and therefore, it is possible to use these simulators in the executive and operational ranks to improve the shooting skills of the officers. Many human and financial losses were prevented.

The aim of the present study was to determine the effect size of the psychological consequences of Internet addiction.

It is fundamental in terms of the purpose and a mata-analysis review in terms of method. The statistical population of the research consisted 95 domestic articles and theses over the past 20 years and 46 articles were selected using non-random sampling with inclusive criteria.

Social isolation (ES, 0.60), aggression (ES, 0.45), mental health (ES, -0.42), stress (ES, 0.40), feeling alone (ES, 0.39), anxiety (ES, 0.39), aggression (ES, 0.45), depression (ES, 0.36), quality of life (ES, -0.28) and sleep quality (ES, -0.22) are respectively the strongest the results were identified. Due to the heterogeneity in studies, studies with validity (ES, 0.27) have a larger effect size than studies without validation (ES, 0.11); also, the effect size of the systematic sampling method (ES, 0.52) was higher than other sampling methods.

In general, the review of research showed that the phenomenon of Internet addiction has significant psychological effects, and therefore it is necessary to consider the framework of researches that have dealt with the psychological factors influencing it; designed programs to prevent and intervene in this destructive phenomenon.
