The present research tried to prompt self-regulated learning, autonomy, and self-efficacy of EFL learners through authentic assessment in Iranian EFL classrooms. To do so, 57 Iranian EFL learners were chosen and assigned to two equal groups; the Experimental Group (CG) and the Control Group (CG). Then, three questionnaires were administered to assess the respondents' self-regulated learning, autonomy, and self-efficacy before doing the treatment. After that, the EG received the treatment via using authentic assessments whereas the CG received the instruction through non-authentic assessments. After teaching 15 English passages to both groups, three post-tests were administered to them to determine the effects of the treatment on their self-regulated learning, autonomy, and self-efficacy. Lastly, the attitude questionnaire was given to the EG students to assess their attitudes toward implementing authentic assessments in EFL classes. The outcomes of ANCOVA revealed that there were significant differences between the post-tests of the EG and the CG. The results displayed that the EG noticeably outdid the CG in self-regulated learning, autonomy, and self-efficacy post-tests. In addition, the results showed that the EG held a positive attitude toward using authentic assessment in EFL classes. It can be concluded that applying authentic assessment in EFL classes can bring about constructive impacts for EFL learners. The findings of this investigation can be extremely valuable for EFL teachers and material designers to consider the impacts of authentic assessments and invest more in using these sorts of assessments.

This study investigates the relationship between the immersive VR experience, destination cognitive image, destination affective image, and tourists' travel intention. The sample of this research is 167 visitors of three tourist attractions of Isfahan Province in Iran, through 360-degree virtual reality videos. In order to collect research data, an online survey and convenience sampling methods were used. PLS-SEM was utilized to assess both the measurement and structural models. The findings indicated that among factors of external technical environment stimuli, media richness has a stronger effect on the formation of the destination's cognitive image than the affective image. Also, perceived interactivity compared to media richness has a significant impact on the formation of the destination's affective image. In addition, vision consistency as an internal technical environment stimulus has a positive effect on the formation of the cognitive and affective image of the destination. Finally, the affective image of the destination resulting from the immersive VR experience has a stronger effect on travel intention than the cognitive image. [ABSTRACT FROM AUTHOR]

Background: Previous studies have shown that physical appearance perfectionism could play an important role in social physique anxiety; however, the moderating role of body compassion has not been studied. The current study aims to explore the moderating role of body compassion in the relationship between physical appearance perfectionism and social physique anxiety in undergraduate students. Methods: A sample of 418 undergraduates (n = 418; 217 female and 201 males) from three universities in Tehran, Iran completed online questionnaires measuring physical appearance perfectionism, body compassion and social physique anxiety. Results: The results of structural equation modeling showed that physical appearance perfectionism (β = 0.68, p < 0.001) positively predicted the social physique anxiety and body compassion negatively predicted (β = −.56, p < 0.001) the social physique anxiety in undergraduate students. A multi-group analysis showed that body compassion acted as a moderator between physical appearance perfectionism and social physique anxiety. Conclusions: The results suggested that individuals with greater levels of physical appearance perfectionism are more likely to experience social physique anxiety. Also, the results suggested that individuals who were at a high level of the body-compassion group experienced lower levels of social physical anxiety if they also had high levels of physical appearance perfectionism. Therefore, body-compassion acted as a protective role in the relationship between physical appearance perfectionism and social physique anxiety. Plain English summary: Anxiety over one's physical appearance in social situations is known as social physique anxiety. One of the variables that plays an important role social physique anxiety is physical appearance perfectionism. General perfectionism, body dissatisfaction, the symptoms of eating disorders and muscle dysmorphia and obsessive exercise are all linked to physical appearance perfectionism. The results of the current study showed individuals with high levels of physical appearance perfectionism are more likely to experience social physique anxiety. In the current study, we tested the moderating role of self-compassion in the relationship between physical appearance perfectionism and social physique anxiety. Body compassion is characterized by diffusion, common humanity, and acceptance of one's own body as opposed to being judgmental, critical, isolated, and over-identifying with unpleasant experiences and emotions. The findings showed in the group with high body- compassion, the relationship between physical appearance perfectionism and social physique anxiety was not significant, which means that body-compassion played a buffering role in this relationship.

Identifying railway capacity is an important task that can identify ‘in principal’ whether the network can handle an intended traffic flow, and whether there is any free capacity left for additional train services. Capacity determination techniques can also be used to identify how best to improve an existing network, and at least cost. In this article, an optimization approach has been applied to a case study of the Iran national railway, in order to identify its current capacity and to optimally expand it given a variety of technical conditions. This railway is very important in Iran and will be upgraded extensively in the coming years. Hence, the conclusions in this article may help in that endeavor. A sensitivity analysis is recommended to evaluate a wider range of possible scenarios. Hence, more useful lower and upper bounds can be provided for the performance of the system.

Background: Unsafe worker behavior is often identified as a major cause of dangerous incidents in the petrochemical industry. Behavioral safety models provide frameworks that may help to prevent such incidents by identifying factors promoting safe or unsafe behavior. We recently conducted a qualitative study to identify factors affecting workers' unsafe behaviors in an Iranian petrochemical company., Objective: The aims of this study were to (1) conduct a review of the relevant research literature between the years 2000 and 2019 to identify theoretical models proposed to explain and predict safe behavior in the workplace and (2) to select the model that best reflects our qualitative findings and other evidence about the factors influencing safe behaviors among petrochemical workers., Methods: This research used mixed methods. Initially, we conducted a qualitative study of factors that Iranian petrochemical workers believed affected their safety behavior. Four themes emerged from the semistructured interviews: (1) poor direct safety management and supervision; (2) unsafe workplace conditions; (3) workers' perceptions, skills, and training; and (4) broader organizational factors. Electronic databases, including PubMed, Embase, Scopus, Google Scholar, EBSCOhost, and Science Direct, were then searched for eligible studies on models to explain and predict safe behaviors, which were published between the years 2000 and 2019. Medical subject headings were used as the primary analytical element. Medical subject headings and subheadings were then extracted from the literature. One researcher conducted the search and 3 researchers performed screening and data extraction. Then, constructs described in each study were assessed to determine which were the most consistent with themes derived from our qualitative analysis., Results: A total of 2032 publications were found using the search strategy. Of these, 142 studies were assessed and 28 studies met the inclusion criteria and were included in the review. The themes identified in the qualitative study most closely matched 3 scales included in Wu et al's model that measured safety behavior and performance, safety leadership, and safety climate in petrochemical industries. Poor direct safety management and supervision matched with safety leadership and its subscales; unsafe workplace conditions matched with safety climate and its subscales; workers' perceptions, skills, and training matched with safety performance and its subscales; and broader organizational factors matched with some subscales of the model., Conclusions: This is the first literature review to identify models intended to explain and predict safe behavior and select the model most consistent with themes elicited from a qualitative study. Our results showed that effective safety leadership and management and safety climate and culture systems are the most frequently identified factors affecting safe behaviors in the petrochemical industry. These results can further help safety researchers and professionals design effective behavior-based safety interventions, which can have a more sustainable and persistent impact on workers' safety behaviors., Trial Registration: Iranian Registry of Clinical Trials IRCT20170515033981N2; https://www.irct.ir/trial/26107., International Registered Report Identifier (irrid): RR2-10.1186/s12889-019-7126-1., (©Azita Zahiri Harsini, Philip Bohle, Lynda R Matthews, Fazlollah Ghofranipour, Hormoz Sanaeinasab, Farkhondeh Amin Shokravi, Krishan Prasad.
