Methodology : The method of the present study was applied based on the purpose and mixed type based on the nature of the data. The statistical population in the qualitative part of the research included all experts in the field of effective skills training, and 30 experts were selected using targeted snowball sampling method. The second group of the statistical population of this study in the quantitative part included all the official teachers of applied science centers in Mazandaran province in the number of 3,000 people who were selected by random sampling and snowball method of 608 people as the sample size. In the qualitative part of the present study, semi-in-depth interviews were used and in the quantitative part, a researcher-made questionnaire was used. The validity and reliability of both instruments were evaluated and confirmed. The method of data analysis in the qualitative part of the theoretical coding was taken from the method of data theory of the foundation and in the quantitative part, confirmatory factor analysis was used to validate the model and determine the relationship between the identified factors. Findings : The results showed that in a total of 6 dimensions of career goals, instructor, environment, student, content and management, 28 components and 252 indicators of the dimensions of the skill training model are effective. Conclusion : Based on the obtained coefficients, it can be said that all indicators have an important and significant role in measuring the dimensions and components of the model of effective skills training system for scientific-applied centers of Mazandaran province

Purpose: One of the indicators of economic development in the countries is the participation of citizens. One of the most important issues is the participation of citizens in paying taxes. Methodology: In this research, a model for promoting popular participation in paying taxes at the Tehran Tax Administration has been addressed.

The statistical population of this study is 384 attendants and 254 employees of the General Directorate. A random sampling method was used. According to the opinion of the professors, the tool was selected through the implementation of 30 questionnaires and the determination of Cronbach's alpha The research used in this study was exploratory factor analysis, T test, Factor Factor Analysis and Verifiable Factor Analysis, which was performed using SPSS software and Lisrel software and MonteCarloPCA program and structural equation modeling technique (SEM). Findings: The research findings show that in this study 8 factors have been discovered to increase the participation and its model has been extracted and approved by the experts. Among these factors, technological and economic have the highest value and have been introduced as the most important factor for promoting participation.

The instrument of this research was a semi-structured interview whose validity was confirmed by the triangulation method and its reliability was obtained by the agreement coefficient method between the two coders 0.90. Data were analyzed by open, axial and selective coding methods in MAXQDA-2018 software. Findings: The results showed that for the aesthetic education of elementary school students were identified 21 indicators in 10 components and 3 dimensions. The dimensions were included constructing learning experiences (with 3 components of reviewing the previous lesson and learning prerequisites, briefly stating the objectives of each lesson and presenting new material along with practice by students), progress in short steps, but at a fast pace (with 3 components of applying an appropriate behaviors with aesthetics features, applying a teaching model and planning for students' learning experiences) and presenting feedback and error correction (with 4 components of applying established learning principles, regular feedback and corrections, performing exercises with clear instructions and guiding students in doing the first exercises).

Cyber transgressions (non-normative behaviors, attitudes and conditions) are growing, hence we employed a three-study exploratory sequential mixed method designed to make a taxonomy of Instagram cybercultural transgressions, and cyber social control means; to examine the effects of low self-control, depression, negative interpersonal relationships, computer/ Internet self-efficacy, netiquette, and normative beliefs, and also sociodemographic factors, and media use habits on cybercultural transgressions; and to explore the effectiveness of jurisdiction, non-anonymity, filtering, and forced user migration to domestic social media platforms as cyber social control means. The quantitative findings from 989 participants showed that nondepressed, older, married, middle-income, university educated, non-student users (especially women) with high self-control, more positive interpersonal relationships, moderate levels of computer/ Internet self-efficacy, normative beliefs, and with more years of Internet use experience, and less daily Internet use, who are knowledgeable about netiquette, are parents, have a job (also retired individuals and housewives), do not use VPNs, psychotropic medications, and alcoholic beverages and/ or recreational drugs, do not have previous experience of online victimization, do not associate with online transgressors, and do not feel being in minority, are less likely than others to commit online transgressive behaviors, or consume transgressive content. The importance of jurisdiction and non-anonymity as social control means, and the failure of filtering and forced user migration to Iranian social media platforms are discussed. These findings can be useful in devising new non-coercive policies and initiatives to socially control cybercultural transgressions.
