The increase of terrorist acts and the essential, methodological and instrumental evolution of terrorism have led to the emergence of various forms of terrorist acts that cannot be combated with conventional and existing patterns. In this study, the researcher has addressed the comprehensive model for the fight against terrorism in order to enhance the domestic knowledge of this phenomenon and to pay attention to the practical needs existed in this field. The researcher by using descriptive-analytical method aims to identify both positive and negative aspects of comprehensive model for fighting terrorism. This model is based on six strategic policies as follows:A) Policies designed and implemented for the purpose of physical confrontation, weakening and/or elimination of terrorist unit, such as information dominance, organizational empowerment and operational dominance. B) Policies designed to socialize counter-terrorism and are meant to create a powerfully integrated society which has a high degree of impenetrability and certitude in potential terrorist acts. From this perspective, the priority is given to strengthen internal consistency, to heighten public awareness, and to increase the threshold of social tolerance and insight.

In recent years, determining the most effective time to post on Instagram for increased engagement has become a central concern for digital marketers. Despite its significance, research on this topic remains limited. This study adopts an exploratory research approach to analyze Instagram posts from selected Western countries (Europe and America) and Iranian businesses. The data were collected during the period from February 21, 2022, to March 21, 2022, employing web scraping tools. Classification algorithms, including XGBoost, K-NN, SVM, and Linear Regression, are employed for modeling, with results favoring the XGBoost method for accuracy. The study reveals optimal posting times between 12 and 3 pm for Western Countries businesses and 9 and 12 am for Iranian businesses. Furthermore, it suggests Sunday as the best day for posting in the West, contrasting with Thursday in Iran. In summary, this research underscores the differing ideal posting times in Iran and the West, emphasizing the challenge of constructing a uniform model for all countries.
