The question that has always occupied the minds of police commanders is what features of police command and management are most beneficial and increase the effectiveness of police missions? The purpose of this research is to know the characteristics of commanding style and police managers based on the teachings of Shahid Soleimani school.

In terms of purpose, the research is applied and in terms of nature, it is a mixed exploratory type based on the Delphi method. The participants included police experts and documents related to the Shahid Soleimani school, which were selected as a purposeful judgment, and the oral and written data collected were analyzed and analyzed in a proof-interpretive way.

73 indicators or sub-categories were identified as the characteristics of police commanders and managers based on the Shahid Soleimani school, which can be divided into six dimensions or categories: belief and spirituality (8 dimensions), personality (12 dimensions), command and management (19 dimensions), Ethical-behavioral (14 dimensions), knowledge-skills (13 dimensions) and foresight (7 dimensions) were classified. The findings show that although the realization of managers and commanders at the level of the Islamic Revolution requires the comprehensive development of these characteristics, the most central category is the religious and spiritual dimension, which forms the basis of all other dimensions.

Having the leadership style of Martyr Soleimani in the police education and training program can lead to the systematic training of commanders and managers at the level of the Islamic Revolution and the school of Martyr Soleimani. It is expected that these characteristics in all behavioral dimensions of police commanders and managers can lead to the police at the level of the Islamic Revolution.

Today, organizations attach great importance to ensuring the physical and mental health of their employees; Because the imposition of severe pressures due to the nature, type or inappropriate condition of work can lead to job loss in them. Based on this, the aim of this research is to identify the effective factors in reducing job attrition of human resources in Iran's governing organizations.

This research is applied in terms of purpose and exploratory (qualitative-quantitative) in terms of execution method. For this purpose, after carrying out exploratory and library studies, the related factors and components came to the opinion of 30 academic and organizational experts through Delphi method, and after receiving their corrective opinions, finally, the model, components and combination of factors were agreed upon by them. Next, in order to evaluate the model, a researcher-made questionnaire among 260 employees of the governing organizations of Mazandaran province who were selected by random cluster method, the distribution and data obtained in this section were also analyzed using confirmatory factor analysis by Smart PLS3 software. became.

According to the findings of the research, four categories of organizational, occupational, individual and environmental factors are effective in reducing job burnout of human resources, and individual factors with an impact factor of 0.434 have the greatest effect on reducing job burnout in these organizations.

In the current research, in addition to the dimensions and components identified in previous studies, new dimensions of factors affecting the reduction of job attrition of human resources were introduced and finally, a comprehensive model was presented for it; So that it reduces the dispersion of the findings of previous researches and emphasizes on coherence and integration.

This study was conducted in the field of human communication skills with the aim of verifying the indicators of the Daffos model of human communication (approved by the Council of Excellence and Development of Amin University of Police Sciences, 2018) and also designing and compiling a resource for training the index of human communication skills.

The research was conducted using a qualitative method and within the framework of thematic analysis. The participants consisted of three groups: a) 43 students of Daffodil in 2019, period 28, who were studying in five classes at the time of the research and were studying human communication; b) professors of human communication course (five people); and c) provincial staff (54 people). In total, nineteen people for the first spectrum, three people for the second spectrum and seventeen people for the third spectrum were selected in a purposeful way until reaching theoretical saturation. The data was collected through expert meetings and separate focus groups. At the end of these meetings, the human communication model of Daffodil students was calculated and designed.

In total, after multiple revisions, fifteen indicators in the individual dimension, ten indicators for the intra-organizational dimension and five indicators for the extra-organizational dimension of human communication were counted.

The model of human communication obtained has been evolutionary and progressive and is based on the model designed and approved by the Council of Excellence and Transformation of Amin University of Police Sciences. Therefore, it is necessary to pay special attention to these dimensions and their indicators in order to improve this characteristic with the importance of command.

Establishing stable security in major sports events is one of the important challenges of those in charge of organizing them in the country. Therefore, the current research seeks to identify factors affecting sustainable security in major sports events in Iran.

This research is practical and exploratory with a mixed approach (qualitative-quantitative). In the qualitative part of the data base theory (Strauss and Corbin 1990) and semi-structured interview with 20 experts who were selected by non-random sampling and face validity and reliability (retest) were used. In the quantitative part of the research, 250 people participated and were collected using a researcher-made questionnaire whose validity and reliability (Cronbach's alpha coefficient 89%) were confirmed and analyzed by multivariate regression test.

Based on the findings, causal factors include proper management, disciplinary and security measures, inter-organizational communication; Background factors include management of fans' emotions, emotional and psychological support; Intervening factors include the implementation of laws and regulations, monitoring of media and virtual space, and sports policies; The strategies included the promotion of culture, social integration, correct education, sports diplomacy, improving welfare and sports infrastructure, investment and financial assistance, technology and information, and the consequences included sports, security and cultural consequences.

It is suggested that the country's sports custodians establish a constructive and unifying determination to create sustainable security by creating unity and empathy by changing the attitude in the country's sports community and with a coordinated management centered on security forces.

A series of crimes with new methods and forms, complexity in the way of committing and with special characteristics at the national and transnational levels, known as "organized crimes", is expanding, which has caused insecurity in both national and international societies. . According to its legal duty, the police is the main custodian of discovering and fighting organized crime. This research has been done with the aim of presenting the pattern of criminalization of organized crimes in the Iranian police.

The present research is applied in terms of purpose and mixed in nature. In the qualitative part, the sample size consisted of 15 knowledgeable experts who were selected based on the theoretical saturation principle of the purposive sampling method. The data collected from the semi-structured interview technique were analyzed and analyzed using the qualitative content analysis method with "Max Kyoda" software. Quantitative part is survey method; The statistical community of this department included 251 specialized police experts, and the sample size was 148 based on Morgan's table and stratified random sampling method. Quantitative part data was collected by questionnaire tool and analyzed through Lisrel software.

The criminalization pattern of organized crimes includes six dimensions (structure, goals, human resources, technology, coordination and interactions, and environment), 18 components and 104 indicators. Also, the pattern identified in the qualitative section was confirmed based on the findings of the quantitative section.

The results of the research show that the pattern of criminalization of organized crimes in the Iranian police can be used in the criminalization of organized crimes and crime detection by the police, and according to the comparison of the current and desired situations and the identification of the gap between these two situations, officials and policy makers The police command of the whole country should take the necessary measures for the implementation of the model.

The problem that today's society is suffering from is the way related institutions and organizations intervene in the crime detection process and get the participation of other governmental and non-governmental organizations and foundations by the judicial system and law enforcement command to manage crimes. The main goal of this research is to design a model of multi-institutional participation in the crime detection process.

This research was conducted with a mixed approach (qualitative-quantitative). The participants in the qualitative part included experts related to the subject, and the statistical community in the quantitative part was selected from experts in related categories in accordance with the crime detection mission. Sampling in the qualitative part is purposeful and in the quantitative stage it is stratified random. The data was collected in the qualitative phase through semi-structured interviews and in the quantitative part using a researcher-made questionnaire (based on the findings of the qualitative phase).

The identification and statistics of the dimensions (five dimensions), components (31 components) and indicators of the multi-institutional partnership model (147 indicators) indicate that there is a significant relationship between all dimensions with the multi-institutional partnership model and, in total, the final multi-institutional model in the process of mass identification was reliably tested.

In the structural dimension, six components include "command and management, control and supervision, organizational structure, planning, functions and organization"; In the environmental dimension, there are seven components including "neighboring systems, law, social obligation, public interest, commitment to society, interaction and cooperation and type of participation"; In the system dimension, five components include "human resource management, reactions, coordination, information and motivation promotion"; In the processes dimension, there are five components including "problems and obstacles, requirements, regulations, complementary programs and professional approach"; In the technological dimension, eight components including "electronic participation, intelligence, media interactions, technology, equipment, training and crime detection knowledge" have the greatest impact in the crime detection process, which indicates the design and presentation of a desirable model of multi-institutional partnership and a meaningful relationship between dimensions. has been identified.

 criminal investigation has rules that realize the foundations of crime detection in a structured information-oriented system, which depends on the correct use of criminal investigation information bases; Therefore, the current research was conducted with the aim of identifying the challenges of intelligence-based policing in criminalizing the theft of places caused by criminal trips.

 The current research is applied in terms of purpose and qualitative in terms of the nature of the data, which has been analyzed using the method of content analysis. The statistical population was detectives and crime detection specialists, 14 of them were selected as participants with a targeted criterion approach and based on the principle of theoretical saturation. The data collection tool was a semi-structured interview, which was used to determine its reliability and validity using the four criteria of credibility, transferability, verifiability and reliability.

 The challenges of intelligence-based policing in criminalizing thefts caused by criminal trips include 67 basic themes, 9 organizing themes and 2 comprehensive themes. Therefore, the first overarching theme, i.e., extra-organizational challenges, includes four organizing themes, and intra-organizational challenges also includes five organizing themes, which are discussed in the text of the article.

 In all societies, crimes and intelligence are closely related to each other, and from the point of view of forensic science experts, one of the most important issues in the improper design of the crime detection process is the lack of sufficient intelligence. Therefore, a useful intelligence system and away from internal and external organizational challenges is important and vital for the success of any police case.
