Structural design extends beyond merely creating forms to withstand forces; it incorporates various technical and non-technical elements within architectural design. The true value of structural knowledge emerges during the design process when these elements are thoroughly understood. Achieving this understanding necessitates the provision of diverse types of structural knowledge capable of informing design and analysis. Additionally, by exploring various structural design methodologies, two principal types of cognition — "geometric" and "numerical" — can significantly help designers navigate the complex requirements of structural design. This research aims to investigate the different forms of structured knowledge relevant to architectural design, ultimately addressing the central question of how geometric and numerical comprehension of structures contributes to the architectural design process. The research employs a descriptive-analytical method with a comparative study approach. It begins by defining and detailing the characteristics of geometric and numerical cognition within the design framework, subsequently elucidating their interrelationship in architectural design. Findings suggest that geometric and numerical cognitions of structures, articulated through distinct languages, correspond to various roles in designing mechanical and spatial aspects, as well as different levels of structural comprehension at various design stages. Geometric cognition, due to its linguistic proximity to the design step, has the capability to examine and apply structural knowledge from the initial stages of form design to its actual construction phase. On the other hand, numerical cognition primarily focuses on the detailed examination of the mechanical and load-bearing aspects of the structure in its analytical step.

Objective: This study aimed to examine the effects of schema-based and mindful parenting training on reducing sleep problems and aggression in children with mild autism spectrum disorder (ASD). Methods: The research utilized a quasi-experimental design with pretest-posttest measurements, a control group, and a one-month follow-up. The study population consisted of 7- to 12-year-old children with mild ASD and their mothers from autism centers in Mashhad, Iran. Forty children (20 boys and 20 girls) and their mothers were selected using purposive sampling and randomly assigned to two intervention groups (schema-based and mindful parenting) and one control group. Both intervention groups received 12 weekly 90-minute training sessions, while the control group received no intervention. Data were collected using the Aggression Questionnaire and the Children’s Sleep Habits Questionnaire and analyzed with SPSS software using one-way ANOVA and covariance analysis (ANCOVA). Findings: Results showed that both schema-based and mindful parenting interventions significantly reduced sleep problems and aggression in children with mild ASD. The schema-based parenting group exhibited notable improvements in child-parent interactions and a reduction in maladaptive behaviors, while the mindful parenting group demonstrated enhanced maternal acceptance, reduced parenting stress, and improved emotional understanding of the child. Post-intervention comparisons indicated significant differences between experimental and control groups, with both interventions yielding positive impacts on sleep quality and aggressive behaviors. Conclusion: The findings suggest that schema-based and mindful parenting approaches can be effective in addressing sleep disturbances and reducing aggressive behaviors in children with mild ASD.

Objective: This study aimed to investigate the relationship between parental overcontrol and adolescent social withdrawal, with fear of negative and positive evaluation as potential mediating variables. Methods: The research employed a descriptive correlational design and included a sample of 551 Nigerian adolescents selected based on the Morgan and Krejcie table. Data were collected using standardized self-report instruments: the Psychological Control Scale–Youth Self-Report (PCS-YSR) for parental overcontrol, the Brief Fear of Negative Evaluation Scale (BFNE), the Fear of Positive Evaluation Scale (FPES), and the Withdrawn/Depressed subscale of the Youth Self-Report (YSR). Descriptive statistics and Pearson correlation coefficients were calculated using SPSS-27, and Structural Equation Modeling (SEM) was conducted via AMOS-21 to examine direct and indirect pathways among the variables. Findings: Pearson correlation analysis showed that parental overcontrol was significantly associated with fear of negative evaluation (r = .51, p < .001), fear of positive evaluation (r = .47, p < .001), and social withdrawal (r = .42, p < .001). SEM results confirmed that the structural model had good fit indices (χ² = 146.23, df = 84, χ²/df = 1.74, CFI = 0.97, RMSEA = 0.041). Parental overcontrol had significant direct effects on fear of negative evaluation (β = .51, p < .001), fear of positive evaluation (β = .48, p < .001), and social withdrawal (β = .27, p < .001). Both fears significantly predicted social withdrawal (FNE: β = .45, p < .001; FPE: β = .38, p < .001). Indirect effects of parental overcontrol on social withdrawal via FNE (B = 0.19, p < .001) and FPE (B = 0.14, p < .001) were also significant. Conclusion: These findings highlight that fear of evaluation—both negative and positive—serves as a psychological mechanism linking parental overcontrol to social withdrawal in adolescents, emphasizing the importance of addressing cognitive-affective vulnerabilities in preventive and therapeutic interventions.

Culture encompasses the values, norms, traditions, beliefs, and customs of a society, with clothing representing one of its most significant elements. In analyzing the traditional attire of an ethnic group, two key aspects are of importance: the cultural patterns influencing choices of material, color, design, and tailoring methods, and the symbolic and functional roles of clothing. Certain garments play vital roles across various social, cultural, occupational, and religious contexts. The Qashqai are one of the major nomadic tribes of Iran, primarily residing in the southern and southwestern regions of the country. The distinctive features of Qashqai clothing set it apart from that of other ethnic groups, despite notable similarities with the attire of the Lurs. Based on archival research and fieldwork, this study explores the historical evolution of Qashqai clothing. It aims to identify the earliest documented references to their attire through textual sources and visual representations, and to discuss the key factors contributing to its continuity. The findings reveal that although traditional Qashqai clothing has undergone changes over time, particularly among men, where modern styles are increasingly replacing it, it continues to be preserved among Qashqai women, especially during ceremonial events.

Online learning is one of the educational channels that learners and educational centers have recently turned to. However, there are still concerns about its effectiveness. The aim of the study was to explain learners' perspectives on the effectiveness of online learning. The present study was a qualitative study using content analysis method that was conducted in 1402. The participants were 38 female (n=22) and male (n=16) language learners from Tehran Language School who had experience in online learning and were selected through purposive sampling. Data were collected and analyzed through interviews. The overall analysis of the interviews indicates that 63% of learners (n=24) rated the method as weak, 20% (n=8) rated the method as average, and 17% (n=6) rated the method as good. 29 percent (n=11) believed that the method was effective in improving their knowledge, and 23 percent (n=9) considered the method effective in improving speaking skills. 15 percent (n=6) are willing to participate in online learning again and 83 percent (n=31) believed that the most important problem of online learning is the lack of necessary infrastructure and 83.6 percent (n=32) of the participants believe that the best learning method to improve English language skills is face-to-face learning. The findings indicate that online learning is not a suitable method for improving English language knowledge and skills compared to face-to-face education and if it is necessary to learn English online, it is necessary to provide infrastructure.
