Rooted in the Cognitive Load (CL) and Dual Coding theories, this sequential explanatory study examined the CL levels experienced by 36 available Iranian pre-intermediate English as a Foreign Language (EFL) learners in auditory and visual Phonemic Awareness Tasks (PATs). The PATs focused on 'th' sound variations that were specifically challenging for Persian speakers of English. Participants were divided into two equal groups. The first group underwent auditory and visual PATs (i.e., picture sorting and word discrimination). The second group faced auditory PATs only (i.e., rhyme recognition and sound isolation) structured around voiced and voiceless ‘th’ sounds. In the qualitative phase, 8 participants were randomly interviewed to discover the potential reasons behind various levels of CL measured in certain PATs. A Virtual Reality (VR) cognitive pupillometry analysis was performed for two groups in an immersive VR environment using VR Head-Mounted Displays (VR-HMDs) and Tobii Nexus software, followed by thematic analysis. GazeMetrics strategies were employed to validate and ensure the reliability of the data collection process. The quantitative results demonstrated (a) no critical differences regarding the CL experienced by the participants in each group concerning voiced vs. voiceless’ th’ PATs and (b) higher levels of CL (increased pupil diameter, decreased blink rates, and increased gaze pattern or fixation duration) among participants in the auditory PATs group compared to the ones in the auditory and visual PATs group. Besides, qualitative findings identified the following factors as the most probable causes of the observed differences in CL levels among participants: (a) segmental differences, (b) phonological transfer, (c) phonological fossilization, (d) working memory constraints, (e) cognitive flexibility, and (f) task delivery methods. This study contributes to cognitive phonology, phonological processing, perceptual-motor language functions, and English material development.

Today, businesses are considered the main factor in improving the country's economy and creating employment through the implementation of policies that foster entrepreneurship and the establishment of supportive institutions. Therefore, the current research seeks to identify factors that affect the development of IT-based platform services. In this research, a questionnaire based on the fuzzy Delphi method was used to identify the factors. The statistical population of this research consists of 20 managers, professors, specialists, and experts who are associated with start-up companies. Due to the small size of the population, the entire population was considered as a sample. In this research, the influential factors were identified using the fuzzy Delphi method. The results of the research showed that providing access to financial resources is the most important factor affecting the development of IT-based platform services. On the other hand, improving the entrepreneurial environment through the establishment of laws is considered the least important factor in this area.

  Subjective : Psychological problems are involved in many psychosomatic disorders. Gastric ulcer is also related to psychological problems as one of the psychosomatic disorders. This research was conducted with the aim of comparison of emotion regulation in gastric ulcer sufferers and non-sufferers. Methods : This research is descriptive and causal-comparative. 100 patients with gastric ulcer and referred to Imam Hussein Hospital in Tehran in 2022 were selected by convenience sampling method and compared with 100 of their companions who did not have gastric ulcer. Both groups responded to Difficulties in Emotion Regulation Scale (DERS). Data were analyzed with multivariate analysis of variance and SPSS-21 software. Results : The findings showed that the total score of difficulties in emotion regulation and its subscales (non-acceptance of negative emotions, difficulties engaging in goal-directed behaviors, difficulties controlling impulsive behaviors, limited access to effective emotion regulation strategies, lack of emotional awareness, lack of emotional clarity) in patients with gastric ulcer is significantly higher than of non-afflicted people (P<0.001). Conclusion : According to this finding, it can be concluded that the difficulty in regulating emotions may play a role in gastric ulcers. It seems that patients with gastric ulcer are less able to identify and understand their emotions and less able to manage their emotions properly. Therefore, the accumulation of psychological pressure caused by negative emotions can cause their symptoms to appear or intensify.

This study aimed to explore Iranian EFL teachers' perceptions of Critical Pedagogy (CP) and their classroom practices. For this purpose, a total of 22 EFL teachers were selected through convenience sampling and participated in an online semi-structured written interview. A sub-group of them also took part in a phone interview. Textual data were analyzed using grounded theory coding types, including open, axial, and selective coding, with MAXQDA software (Version 2020). The findings revealed two broad themes: raising students' critical consciousness and learner-centered pedagogy for CP definition, and communicative tasks and learner-centered activities for CP classroom practices. Additionally, the dominant barriers to the implementation of CP in the Iranian EFL context were identified as the top-down educational system, teachers' variables, and practical barriers.
