This study aims to determine whether the perceived ease of use and perceived usefulness can significantly predict the students’ intention to use video conferencing applications in an online classroom. This study utilized a descriptive predictive quantitative research design. This study used the survey questionnaires adopted from the study of Salloum et al. (2019). The researchers conducted an online survey using Google form for over a month. Out of 153 target respondents, 130 responded to the survey questionnaire. Linear regression was initiated using JASP 0.16.0.0. The findings revealed that the two variables perceived ease of use and perceived usefulness can both significantly predict the students’ intention to use video conferencing applications in an online classroom. The results further showed that the perceived ease of use can better predict the students’ intention to use video conferencing applications in an online classroom as compared to perceived usefulness. The findings imply that video conferencing applications used in the teaching and learning process should be user-friendly and pedagogically relevant to support students’ desire to use video conferencing applications.

INTRODUCTION: The present study aimed to investigate communication, information exchange, cooperation, and trust networks in Iran's Humanitarian Supply Chain at both inter-organizational and interpersonal levels. METHODS: This applied research was conducted based on a descriptive survey design. The statistical population of this research included the organizations and people involved in relief operations performed in three recent disasters: the fire-induced collapse of the Plasco building, Shahran gas explosion, and the flash flood in the Tehran subway. In order to analyze networks, a questionnaire containing network analysis questions was designed. Upon the completion of the questionnaires, the data of each network were entered systematically into a matrix on an excel spreadsheet. Such indexes as degree centrality, betweenness centrality, intersection points, isolation points, and network density were calculated by Ucinet and NetDraw software packages; therefore, the networks were analyzed. FINDINGS: Based on the results obtained from the analysis of communication, information exchange, and cooperation networks, the network density was 21%, indicating a low level of organizational relationship. At this level of communication, information exchange and cooperation were obtained at 11.5% and 16.5%, respectively. The analysis of the trust network also illustrated that the density of this network was 26.6%, suggesting that out of 21% of connections, there was about a quarter of possible trust. This is suggestive of low levels of inter-organizational Trust. CONCLUSION: Building trust in Iran's humanitarian service supply chain can be very effective in the acceleration of service supply, organization, and success of relief operations

Purpose: Covid-19 pandemic increased the use of e-learning and the ensuing academic stress. This research aims to study the relationship between e-learning induced academic stress and academic self-efficacy in the Yazd branch of Payame Noor University in Iran. Methodology: This is a descriptive-correlational study. The study population was the Yazd branch of Payme Noore University students in the 2020-21 academic year. Cochran’s formula gave us a sample size of 319 people. Due to the Covid-19 pandemic and the unavailability of some of the sample members, we used voluntary sampling. Our research tools were the academic stress scale (Pooladi Reyshahri, 1995) and the academic self-efficacy scale (Owen and Froman, 1988). We sent the scale to the subjects electronically. The scales’ alpha Cronbach reliabilities were 0.90 and 0.84, respectively. We analyzed the data using the T-test, correlation, and regression in SPSS version 21. Findings: Our findings showed that e-learning induced academic stress, and its subscales (academic conditions and economic environment stresses) were significantly below average in the students. Students’ academic stress and academic self-efficacy were significantly and inversely related. Academic stress could significantly explain self-efficacy (P < .001). Conclusion: Our results showed the negative role of academic stress in explaining students’ academic self-efficacy. Reducing students' academic stressors through academic workshops can significantly increase academic self-efficacy.

Purpose: This research was conducted with the aim of identification and analysis of effective factors on the strategic intelligence of education districts managers of Tehran city and provides an appropriate model. Methodology: The present study in terms of purpose was applied and in terms of implementation method was descriptive from type of quantitative. The study population was managers, deputies and experts of the education nineteen districts of Tehran city in 2020 year, which based on the Krejcie and Morgan table the sample size was estimated 120 people who were selected by randomly sampling method. The research instrument was a researcher-made questionnaire of effective factors on the strategic intelligence of managers (113 indicators) which after two Delphi rounds with Kendall coefficient of 0.678 was designed by 15 experts and its content validity was confirmed by experts and its reliability was calculated by Cronbach's alpha method 0.921. Data were analyzed by exploratory factor analysis and structural equations modeling in SPSS-22 and Smart PLS-3 software. Findings: The findings showed that the effective factors on the strategic intelligence of managers had 113 indicators in 21 components and 2 dimensions; So that the intra-organizational dimension were included 11 components of intelligent planning, support processes, communication processes, power of change and transformation, knowledge management, educational intelligence, moral intelligence, informational intelligence, organizational process intelligence, human resource intelligence and financial resources intelligence and extra-organizational dimension were included 10 components of business intelligence, environmental intuition thinking, technological intelligence, planning intelligence, social intelligence, competitors intelligence, policy-making, communication with people intelligence, targeting intelligence and environmental macro intelligence. Also, the factor load of all dimensions and components was higher than 0.40, their average extracted variance was higher than 0.50 and their reliability was higher than 0.70. In addition, the model of effective factors on the strategic intelligence of education districts managers had a good fit and the model had a significant effect on the intra-organizational and extra-organizational dimensions and the mentioned dimensions on the relevant components (P<0.05). Conclusion: The results showed two dimensions of intra-organizational and extra-organizational for the model of effective factors on the strategic intelligence of education districts managers. Therefore, to increase and enhance their strategic intelligence can be done by improving the dimensions and components of each of them.
