Background: Understanding color preference in virtual environments is crucial for applications in digital design, human-computer interaction, and virtual reality (VR).Aims: This study examines how luminance, hue, and saturation influence color preference in VR settings, considering both environmental and perceptual factors.Methodology: A controlled VR experiment was used, where participants interacted with two distinct virtual zones designed to simulate different lighting conditions.Finding: The findings suggest that chromatic lightness and perceived hue play distinct roles in color preference, with evidence supporting Weber's Law of illumination adaptation. It was also shown that regions with elevated chroma exhibit more pronounced colors. Additionally, the participants' average color preferences were determined, and the appropriate modification rate was extracted by comparing the preferred colors to the average colors of the virtual spaces. One significant finding was that, cooler colors were favored to warmer ones, which is consistent with previous research on color preferences. Furthermore, a correlation between lighting circumstances and color preferences was established.Conclusion: The findings indicated that adjusting the hue, saturation, and brightness can improve the design of virtual environments by matching the tastes of users. These insights contribute to a deeper understanding of color perception in digital spaces and have implications for design, architecture, and cognitive science.

The meticulous examination of discourse analysis, particularly the scrutiny of language application in academic writing, carries significant weight in the realm of Applied Linguistics. A critical aspect of this exploration revolves around the deployment of stance markers, which function as linguistic tools for articulating the personal viewpoints and assessments of writers concerning the assertions they proffer. The primary objective of this study was to juxtapose the overall and categorical distribution of stance markers in academic research articles authored by native (English) and non-native (Iranian) academic writers across the spheres of soft and hard sciences. The analytical framework of Hyland (2005b) on interactional metadiscourse was utilized to delineate the specific taxonomy of stance markers employed in the academic research articles written by two groups of authors. The results of the research revealed significant differences in the overall and categorical distribution of stance markers between the two sets of datasets, highlighting the potential impacts of disciplinary and cultural variations on their usage. The study advocates for an enriched understanding and integration of the rhetorical norms inherent in academic genres, including the deployment of stance markers, to enhance the creation of educational materials and elevate the language proficiency of students in linguistic studies.

Background: The FIFA 11+ program has been shown to be effective in improving physical fitness factors and preventing injuries in soccer players.Aim: The purpose of this study was to review the effect of the FIFA 11+ injury prevention program on youth soccer players’ performance.Materials and Methods: Relevant articles were searched in Science Direct, PubMed, Scopus, PEDro, and Google Scholar using the keywords "FIFA 11+", "performance", and "youth". The search yielded 32 articles, of which 14 were shortlisted, and ultimately, four were selected for review.Results: The reviewed articles have indicated that the FIFA 11+ program results in a significant improvement in various performance factors (P < 0.05). These studies demonstrated that the FIFA 11+ program enhances stability, knee flexor muscle strength, sprint performance, agility, Slalom Dribbling, and flexibility. However, no significant improvements were observed in long jump, vertical jump, VO2max, balance, and lower extremity range of motion.Conclusion: Studies suggest that the FIFA 11+ warm-up program is more effective than conventional warm-ups in enhancing performance. Therefore, based on the literature reviewed, the FIFA 11+ program is recommended to enhance muscle strength, flexibility, and agility, thereby reducing injury risk in youth football players.

The southern part of Lorestan province in Pishkuh is one of the key areas for understanding the cultural periods of Southwest Iran. This area is located near one of the government centers of Elam (Susa in the south) and on two communication routes from south to north and west to east. Therefore, this area can be one of the essential communication areas between the Susa and the Mesopotamian lowlands, the mountainous region of Zagros, and the central plateau of Iran. However, due to the focus of Elam scholars on the two state centers of Susa and Anshan, there is no comprehensive picture of the state of settlements in this region during the Elam period. Based on this, this research aimed to determine and analyze the situation of the Elamite settlements in the area by conducting a systematic archaeological survey in 2016. As a result, 31 sites belonging to the Elamite period were identified. This research showed that most of the Elam sites were formed in the intermountainous valleys and the slopes of mounds. Most of them have a chronological sequence, and in terms of morphology, they show evidence of Elamite nomadic settlements in this region.

Objective: This study aimed to investigate the effectiveness of Emotionally Focused Couple Therapy (EFCT) on differentiation of self and the reduction of intolerance of uncertainty in couples seeking divorce. Methods: The research method was quasi-experimental with a pretest–posttest control group design. The statistical population consisted of couples seeking divorce in Tehran, from which 30 couples were selected through convenience sampling and randomly assigned to experimental and control groups. The experimental group underwent a 10-session EFCT intervention, each session lasting 90 minutes, while the control group did not receive any intervention. Findings: Findings showed that Emotionally Focused Couple Therapy significantly increased differentiation of self and reduced intolerance of uncertainty in couples seeking divorce. Conclusion: These results suggest that by focusing on core emotions and emotional interactions, it is possible to improve interpersonal relationships and facilitate more informed decision-making in marital relationships. Accordingly, the use of EFCT is recommended in psychological interventions related to divorce crises.

Objective: This study aimed to examine the direct and indirect relationships between spousal support and marital satisfaction, with gratitude expression as a mediating variable. Methods and Materials: A descriptive correlational design was employed with 370 married individuals from Armenia, selected based on the Morgan and Krejcie sampling table. Data were collected using standardized instruments for marital satisfaction, spousal support, and gratitude expression. Analyses were conducted in two stages: Pearson correlation analysis in SPSS-27 to examine bivariate associations, and Structural Equation Modeling (SEM) in AMOS-21 to test the hypothesized mediating model. Model fit was evaluated using established indices, including χ²/df, GFI, AGFI, CFI, TLI, and RMSEA. Findings: Pearson correlations revealed that spousal support was significantly associated with both marital satisfaction (r = .58, p < .001) and gratitude expression (r = .51, p < .001), while gratitude expression was also correlated with marital satisfaction (r = .46, p < .001). SEM demonstrated acceptable model fit (χ²/df = 1.93, GFI = 0.93, AGFI = 0.91, CFI = 0.96, TLI = 0.95, RMSEA = 0.049). Direct effects showed that spousal support positively predicted marital satisfaction (β = 0.37, p < .001) and gratitude expression (β = 0.44, p < .001), while gratitude expression also predicted marital satisfaction (β = 0.29, p = .001). The indirect effect of spousal support on marital satisfaction through gratitude expression was significant (β = 0.13, p = .002), confirming partial mediation. Conclusion: Findings underscore the dual importance of supportive behaviors and gratitude expression in shaping marital satisfaction. Spousal support enhances satisfaction both directly and indirectly by fostering gratitude, suggesting that couples who both provide support and express appreciation are more likely to sustain fulfilling relationships.
