The research population was students and graduates of the PhD period of humanities fields at the Islamic Azad University in 2020-21 academic years, which from them number of 12 people were selected as a sample according to the principle of theoretical saturation and with the purposeful sampling method. Data were collected by semi-structured interviews whose validity by 15 professors was obtained by the relative content validity coefficient method 0.84 and its reliability by the Holsti coefficient method was obtained 0.83. Finally, the data were analyzed by methods of open, axial and selective coding and thematic analysis in MAXQDA-18 software. Findings: The findings showed that managing the challenges of thesis writing in the educational-research field had 74 indicators, 13 components and 4 dimensions. The educational gap dimension has includes three components of computer and software training gap, the lack of familiarity with new research methods and the gap in the practical thesis writing course, choosing the subject dimension has includes three components of lack of paying attention to interdisciplinary subjects, lack of suitable guide for choosing subject and not lack of paying attention to students' interests, cooperation of professors dimension has includes five components of back-promising, restrictions on the selection of supervisors, scientific disability of supervisors, lack of access to professors and lack of commitment and responsibility and educational content dimension has includes two components of lack of access to first-hand sources and lack of easy access to content. Finally, pattern of managing the challenges of thesis writing in the educational-research field was drawn using the theme network method. Conclusion: According to the results of this research, planning it seems necessary to managing the challenges of thesis based on the identified dimensions, components and indicators.

This study aimed to compare impulsivity, sleep disorder, and suicidal thoughts in marijuana users and non-users. The present study was a comparative causal study. The statistical population of this study included students consuming marijuana as well as non-consuming students at the University of Gilan. Fifty male students consuming marijuana in the age group of 18 to 33 years were selected by purposive and snowballs sampling, and 50 non-consuming students were selected and placed in the other group. Participants completed the Bart (1995) Impulse Scale, the Pittsburgh Sleep Quality Index (1989), and the Beck Suicide Thought Scale (1961), respectively. Data were analyzed using multivariate analysis of variance, chi-square test, and independent t-test with SPSS-22 software. The results showed that marijuana users scored higher on all three subscales of impulsivity, i.e., cognitive, motor, and unplanned impulsivity, and showed a significant difference with the non-consumer group. In terms of sleep disorders, marijuana abusers in six subscales out of seven subscales, i.e., mental quality, sleep delay, sufficient sleep, sleep disorders, hypnotic drug, and daily sleep disorders, a significant difference with the non-consumer group. Moreover, in the suicidal ideation scale, people with marijuana abuse had a higher mean score on the Beck suicidal thoughts scale. Conclusion: The research findings can be used in designing therapeutic interventions for people addicted to marijuana.
