This study was conducted to investigate the mediating role of time attitude and time metaphorical perception in the relationship between mindfulness and procrastination. The method of this descriptive-correlation study was based on structural equation modeling. The statistical population of the research included all the students of the Islamic Azad University- Karaj branch in 2023, from which 300 students were selected through available sampling. The participants completed the Procrastination, Mindfulness, Time Attitude Scales, and Time Metaphorical Perception Questionnaire. Data were analyzed using Pearson correlation and structural equations modeling. The results showed that procrastination had negative and significant relationship with mindfulness. The effect of positive time attitude and time metaphorical perception on mindfulness was positive and directly meaningful and the effect of negative time attitude on mindfulness was negatively significant. Furthermore, time attitude and time metaphorical perception played mediating role in the relationship between procrastination and students' mindfulness. On the other hand, the procrastination had a negative and significant relationship with mindfulness through the mediation of negative time attitudes. Therefore, it is suggested that behavioral sciences researchers should pay attention to factors related to time from different dimensions to study the foundation of students' procrastination.

Lack of aboriginal governance model, which is appropriate to national, cultural and ideological circumstances of Iran, is one of the most important problems in the development process of Iran. This paper used Meta-Analysis Method (MAM) to combine the findings of other researches and tries to take a step forward in developing the Iranian Governance model. In this study, 68 articles and reports about governance issues published in the period from 2003 to 2015 have been studied. These articles have been obtained from the four main scientific databases in two main parts including descriptive finding and analytic qualitative finding. In the descriptive part, we used six indicators for description of the articles includes types of article, publishing period, typology, researchers’ gender, geographical distribution, and research methods. Quiddity, knowing why and knowing how were the three main indicators, due to the Belicky's research, for the analytical part. The results of the meta-analysis showed that Iranian researches in the field of governance are in the scope of knowing why and their articles are more about quiddity of governance and why governance models are needed. Although there are some serious criticisms for this theory, “Good governance” is the dominant theory among Iranian researchers. Some researchers have developed “Islamic Good Governance” models but these recommendations seem too intellectual and theoretical and because of the paradoxical roots they will not be very useful.
