Purpose: Today, the issue of academic failure is one of the most important and scrutinized factors in educational systems and examining the effective factors on it can help in better understanding this phenomenon and providing solutions to its reduce. Therefore, the current research was conducted with the aim of modeling the academic failure of senior students based on the socio-economic position and family social capital with the mediation of family chaos. Methodology: This study in terms of purpose was applied and in terms of implementation method was quantitative from type of correlational. The population of the present research was the senior students of Mazandaran province, which 170 people of them were selected as a sample by cluster sampling method. The research tool was a researcher-made questionnaire of effective social factors on academic failure, which had four components of academic failure, socio-economic position, family social capital and family chaos. The face validity of the questionnaire was confirmed by education specialists and experts and its reliability was obtained with Cronbach's alpha method above 0.70. The data were analyzed with tests of regression and structural equation modeling from type of path analysis in SPSS and LISREL software. Findings: The findings showed that all three variables of socio-economic position, family social capital and family chaos separately had a significant correlation with the academic failure of senior students and were able to predict the 31.0%, 20.2% and 22.9% of the changes of their academic failure, respectively. Also, all the three mentioned variables together could predict 51.6% of the changes of academic failure of senior students. In addition, the academic failure model of senior students based on the socio-economic position and family social capital with the mediation of family chaos had a good fit, and in this model, the variables of socio-economic position and family social capital on family chaos and academic failure and the variable of family chaos on academic failure had a direct and significant effect and the variables of socio-economic position and family social capital with the mediation of family chaos had an indirect and significant effect on academic failure (P<0.001). Conclusion: According to the results of this study, in order to reduce the academic failure of senior students can provide the basis for improving the socio-economic position, increasing the family social capital and reducing the family chaos.

Purpose: The knowledge transfer in educational systems, especially higher education plays an important role in improving their educational and non-educational functions. Therefore, the purpose of this study was to present the strategic orientation model of knowledge transfer in University of Applied Sciences and Technology. Methodology: This study in terms of purpose was applied and in terms of implementation method was descriptive from type of correlation. The research population was all the managers and employees in University of Applied Sciences and Technology in Tehran city with number 450 people. The sample size based on Cochran's formula was estimated to be 207 people, who were selected by multi-stage cluster sampling method. The tool of the present study was a researcher-made questionnaire with 36 items, whose face validity was confirmed by the opinion of experts and its reliability was calculated by Cronbach's alpha method 0.95. The data after collecting with a researcher-made questionnaire were analyzed with the methods of exploratory factor analysis in SPSS and Smart PLS software. Findings: The findings of the present study showed that the strategic orientation model of knowledge transfer in University of Applied Sciences and Technology has 36 items in 6 categories including causal factors (with 6 items), central phenomenon (with 3 items), contextual factors (with 7 items), intervening factors (with 4 items), strategies (with 14 items) and consequences (with 2 items), which their factor load was higher than 0.40, their average variance extracted was higher than 0.50 and combined and Cronbach reliability was higher than 0.70. Also, the strategic orientation model of knowledge transfer in University of Applied Sciences and Technology had a good fit and the causal factors had a direct and significant effect on the central phenomenon. The central phenomenon, contextual factors and intervening factors had a direct and significant effect on the strategies and the strategies had a direct and significant effect on the consequences (P<0.001). Conclusion: The results of this study about the strategic orientation model of knowledge transfer in University of Applied Sciences and Technology can help the officials and planners of the University of Applied Sciences and Technology to improve the educational status of the university through knowledge transfer.

Social media platforms like Instagram facilitate connections among individuals through the sharing of images and videos, substantially augmenting the potential for influencing their audience. An area of particular interest that has evolved in recent years, especially with the growth of the virtual space and the visual-centric content on Instagram, is the level of satisfaction individuals have with their physical appearance, particularly among women. Their contentment with their appearance is intricately linked to the idealized beauty standards championed by Instagram beauty bloggers, often inspiring them to emulate or even contrast with these models. In cases where individuals deviate from Instagram's beauty standards, their definition of beauty still reflects certain parallels with these standards. For instance, they do not necessarily consider excess weight as a criterion for beauty, much like the Instagram models, who serve as symbols of conventional beauty, rarely possess excess weight. This qualitative research studied this subject through interviews with six female university students aged 20-30 in Tehran. The study aims to explore the influence of Instagram on their self-perception, satisfaction with their physical appearance, and their notions of beauty and desirable aesthetics. The research process involved a comprehensive review of key concepts and relevant literature, followed by the analysis and comparison of the interview themes. The study's findings, derived from an in-depth examination of these themes and concepts, provide a more profound understanding of the participants' mental constructs within the virtual space, shedding light on the substantial impact of this digital environment on individual mindsets.
