The optimal implementation of Computer Assisted Language Learning (CALL) in Iranian EFL higher education faces some challenges despite its incremental growth. It is, therefore, necessary to investigate the current challenges affecting university professors' and students' adoption of CALL in Iranian EFL contexts. For this purpose, data were collected through semi-structured interviews with three purposeful sampling groups of participants, both before and after the temporary shutdown of the educational sector due to COVID-19 spread. Therefore, 33 interviewees—university EFL professors, students, and Information Technology Support Engineers (IT-SE)— took part in an interview which took approximately 90 minutes for each, conducted in person or over WhatsApp and Skype platforms. All the interviews were audio recorded and transcribed for thematic analysis by the first researcher and an assistant researcher. The obtained results highlighted nine major categories of themes that indicated the obstacles and challenges of optimal CALL implementation. These challenges are related to 1) technological dimension, 2) teacher dimension 3) student dimension, 4) software and hardware dimension, 5) sanctions and filtering dimension, 6) curriculum dimension, 7) the nature of e-learning dimension, 8) socioeconomic and cultural dimension, and 9) university administrators' dimension.  It was the sanctions and filtering dimension, the nature of e-learning dimension, and the socioeconomic dimension that were exclusive to this study. Each of these major themes includes a set of minor themes. The results can contribute to educational planners, curriculum and material developers, and teachers to develop education programs for optimal CALL implementation in Iranian EFL higher education by removing the challenges.

Teachers’ Continuous Professional Development (T-CPD) is of utmost importance for language teachers. T-CPD is the stimulation for updating teachers’ subject knowledge and  their teaching skills. Therefore, the predictive power of Psychological Well-being, L2 Teacher Grit, Grit-s, and Perceived Organizational Support (POS) on T-CPD was investigated through the mediating role of Work Motivation. Those who have participated in this study were 189 L2 teachers, who were from Khorasan Razavi Province, Iran. They took part in an online questionnaire. The collected data was analyzed using Path Analysis. Before running path analysis, Confirmatory Factor Analysis (CFA) was run to estimate Cronbach’s Alpha. Based on the CFA, two items (one from L2 Teacher Grit and one from POS) that did not have good loadings were removed from the scales. Then, the authers used path analysis to check the causal relationship among the variables in the proposed model. The fitness indices showed good fitness. Moreover, the more domain-specific L2 Teacher Grit performed better than the Gris-s scale. These insights can inform strategies for enhancing T-CPD and improving the overall quality of education. In addition, the results put light on the design of teacher training programs and organizational policies that aim to improve teacher quality and student outcomes.

The significant wave height is a critical parameter in the design and analysis of marine structures, as well as in their operational use. Consequently, predicting this parameter greatly contributes to improving the design and analysis of marine structures. Various modeling approaches for wave characteristics include numerical, empirical, and artificial intelligence models. This study employs the SWAN model, which is a third-generation model for the simulation and estimation of wave characteristics. Furthermore, soft computing models, including individual and hybrid artificial intelligence models such as Adaptive Neuro-Fuzzy Inference System (ANFIS), Support Vector Machine (SVM), and Emotional Artificial Neural Networks (EANN), have been utilized for wave height prediction, using data from the Amirabad buoy for validation purposes. In this research, the model inputs consist of wind speed, while the outputs are the wave heights. The analysis of the different models was carried out using statistical metrics, including bias, root mean square error, coefficient of variation, and coefficient of determination. The evaluation of the models using these statistics indicates an acceptable agreement between the significant wave heights estimated by the SWAN model and the buoy data. Additionally, each of the three artificial intelligence models mentioned demonstrates a relatively accurate capability in predicting wave height. A comparison of the results from the artificial intelligence models revealed that the Support Vector Machine model exhibited higher accuracy than the others. The Support Vector Machine model serves as an alternative method to the SWAN model or other numerical techniques, enhancing modeling outcomes when wave height data is unavailable or lacks the necessary statistical quality.

The theory of the responsibility to protect was approved in 2005 in the output document of the United Nations Summit (A/RES/60/1) and in 2011, it was included in the Security Council Resolution 1973 regarding military intervention in Libya. The theory of the responsibility to protect implies the commitment of the international community to end the worst forms of violence and crime in humanitarian crises and internal armed conflicts. This article by using the qualitative method and document-library sources, books, articles and reports and internet notes, dealing with NATO's military intervention in Libya in 2011, which led to airstrikes, the creation of a no-fly zone, and ultimately the change of Muammar Gaddafi's regime,  criticizes its application in Libya.The findings of the article show that although the theory tries to fill the gap between the former obligations of UN member states under international humanitarian law and human rights with this reality that the human population facing the threat of genocide, crimes against humanity, ethnic cleansing and crimes against humanity must be supported, France, the United States and NATO have exploited the 1973 resolution for their political-military goals and have caused the stoppage of the development of the theory and the skepticism of the international community towards the goals and intentions of the world powers in the application of the theory and as a result of the design of the new approach of responsibility during support.

Autonomy support environments and Job involvement among University of Tehran’s employees: The mediating role of Basic psychological needs. As feedback and an important variable in enhancing an organization’s effectiveness, job involvement causes and consequences recognition is of great importance to managers, and an ultimate goal for organizational behavior management. Considering the importance of self-motivation in job involvement, it is necessary to illuminate job involvement through a motivation theory, for instance: self-determination theory. This theory states that work conditions which allow basic psychological needs fulfillment, pave the way for job involvement. Little research studying the relationship between these needs’ fulfillment and employees’ job involvement have been conducted, which calls for more research on this subject. This research is based on a correlation analysis, utilizing structure equation modeling methods. The Statistical population studied here is all of Tehran University’s employees, through which 113 people have been randomly chosen. Research findings show that autonomy support environments have a significant effect on fulfilling mental needs (0.6) , and that mental needs fulfillment, in turn, has a direct significant effect on job involvement (0.54). Moreover, indirect effects of autonomy support on job involvement’s significance (0.33), indicates the intermediary role of mental needs fulfillment in relation to these two variables.

Proof paradoxes refer to situations in which statistical evidence indicates that a suspect is the perpetrator, yet a conviction based solely on this evidence appears counterintuitive. The prevailing approach to addressing proof paradoxes involves establishing a criterion for distinguishing naked statistical evidence from other type of evidence. Smith introduces normic support as a criterion for the aforementioned distinction. Conversely, Di Bello proposes a modified version of normic support, arguing that the absence of access to undercutting defeaters in naked statistical evidence distinguishes it from other forms of evidence. In this research, we argue, in line with Pollock's perspective, that undercutting defeaters can still be accessed in the context of naked statistical evidence. Furthermore, by focusing on an example of proof paradoxes and drawing on Pollock's arguments-illustrated quantitatively by the base rate fallacy-we demonstrate the effectiveness of undercutting defeaters. Consequently, Di Bello's argument appears to be questionable.

Research Subject: In recent years, industrial-scale production of propylene based on oxidative dehydrogenation of propane has been of particular importance due to the lack of thermodynamic limitations. In this regard, the use of natural zeolites with high abundance and low price has placed a special position. In this research, perlite natural zeolites were treated with ionic liquid solution and acid, then supported vanadium catalysis were synthesized. Performance of catalysis were investigated in oxidative dehydrogenation of propane to propylene process with a mixed feed of propane and air in a fixed bed quartz reactor under condition of atmospheric pressure and temperature of 500˚C with a flow rate of 40000 h^-1 (GHSV).
Research Approach: In this study, natural perlite support as a source of aluminum oxide (Al₂O₃) and silica (SiO₂) was ion exchanged by one molar solution of ammonium nitrate (NH₄NO₃ 1 M). Continuously, to investigate the effect of delamination, different acid molar concentrations of nitric acid (HNO₃) equal to 0.75, 1.5, and 2.25 were used and then compared with the just modified ion exchange sample without acid leaching (V/PERLIT-I). Dry vanadium impregnation, as an active metal, was carried out to synthesize 8% wt. catalysts. X-ray diffraction analyzes (XRD), scanning electron microscopy (FE-SEM), and ammonia Temperature-programmed desorption program (NH₃-TPD) were used to characterization and evaluate the properties of the catalyst.
Main Result: The results showed that the concentration of acid used affects the conversion and selectivity of the catalysis. In comparison, a significant difference was observed between the performance of V/PERLIT-I sample compared to V/PERLIT-IA samples. The maximum selectivity value for V/PERLIT-IA(2.25) was 74%. According to the results, the treated perlite support with suitable selectivity can be considered in the studies of use as an industrial support.
