This study examined the relationship between future orientation and well-being mediated by school connectedness. Data were collected from 380 high school adolescents in Shiraz (Iran) in 2021. Participants completed the Future-Orientation Questionnaire, the Psychological Sense of School Membership scale, and Warwick-Edinburgh Mental Well-Being Scale (WEMWBS) to assess their future orientation, school connectedness, and well-being, respectively. Results revealed that students’ future orientation (toward academic or career futures) was positively related with school connectedness (b = .78). Future orientation was also significantly associated with their feeling of well-being (b = .61). School connectedness was significantly associated with the feeling of well-being as well (b = .62). According to the results, future orientation had an indirect significant effect (b = .48) on the well-being; based on this, school connectedness played a significant mediating role in the relation between future orientation and well-being. The results recommend that school connectedness may be a mechanism by which adolescents’ orientation toward academic or career futures may have an effect on their feeling well-being.

The study was conducted to determine the effect of mindfulness training on cognitive flexibility in sixth-grade female students. This research used a pretest-posttest study with control group. A multi-stage random sampling was used in 4 schools, among which 37 sixth-grade female students were randomly selected and assigned to two experimental (17 students) and control groups (20 students). Students in the experimental group participated in a mindfulness training course for 12 (120-minute) sessions for a month and a half. The study used Dennis and Vander Wal's Cognitive Flexibility Inventory (2010). The results of covariance analysis showed that there was a significant difference between the two groups in the scores of cognitive flexibility and due to the higher mean scores of the cognitive flexibility of the experimental group in the posttest (p> 0.05, p = 10.25), it can be stated that mindfulness training was effective in increasing students' cognitive flexibility.

The kind of feeding and feed conditions affect on fish quality. They also affect on proximate composition and fish shelf life. Hence the aim of this study was the evaluation of qualitative changes among the carps culturing in a pond (CCP)¡ an under controlled place (CL) and marine carp (MC) during refrigeration. In order to perform this study¡ the fish was stored at 4◦C for 15 days. During the storage time¡ qualitative changes were evaluated with recording changes in their Total Volatile Bases Nitrogen (TVN)¡ Thiobarbiotic Acid (TBA)¡ Free Fatty Acids (FFA)¡ pH¡ WHC and heme iron. The proximate compositions of fish fillet (moisture¡ protein¡ lipid and ash) were evaluated. The results showed that the highest value of moisture and the lowest value of lipid were observed in CCP. Protein levels among different treatments did not have significant difference. TVN¡ TBA and FFA increased during refrigeration. pH changes didn’t follow an identical pattern in all treatments. The highest level of TBA and FFA and the lowest level of heme iron were observed in CCP. The highest level of WHC was observed in marine carp. The results showed that CCP had more potential to decay.
