This study aims to investigate the role of first language literacy and reading habits in L2 development. the researcher invited a group of 97 pre-intermediate and intermediate learners from various schools to participate in this study. They were asked to take part in two L1 tests (L1 reading comprehension and L1 spelling) as well as an L2 achievement test. Correlation was used to find the possible relation between L1 literacy and L2 development and in order to find out which of the two subcomponents of L1 literacy can better predict L2 development, regression was used. The findings show that there is a meaningful relationship between L1 literacy and L2 development. Both reading comprehension and spelling knowledge of L1 can lead to L2 development; the statistics revealed that both can preferably lead to L2 development and L2 literacy. But in this study, reading comprehension has the strongest impact on L2 development.

In the Industry 4.0 era, many pioneering industries are leveraging emerging technologies such as the Internet of Things (IoT) as solutions in the digital age. One of the largest and most active industries in Iran is the food industry, which stands to benefit significantly from these advancements. Achieving a sustainable competitive advantage is often possible at the level of the supply chain, where companies use information and communication technologies, such as IoT, to coordinate information, finances, and materials among supply chain actors. This research aimed to identify the key success factors (KSFs) for implementing IoT in the food supply chain. Firstly, through a systematic literature review, the KSFs for IoT implementation in the food supply chain were identified. To develop a measurement model, confirmatory factor analysis using structural equation modeling was employed, making the research applied-descriptive. A questionnaire was designed and completed by 142 members of the "Amadeh Laziz" supply chain (a case study), who were selected using a stratified random sampling method. Confirmatory factor analysis and LISREL 8.83 were then used to validate the proposed model. Finally, the cause-and-effect relationship between KSFs in IoT implementation in the food supply chain was analyzed using Grey DEMATEL. Based on the confirmatory factor analysis findings, the KSFs in implementing IoT in the food supply chain were identified as technical, economic, legal, cultural and social, security, applicability of IoT throughout the supply chain, and implementation of IoT applications. Thus, the measurement model included eight factors and 27 measures. According to the cause-and-effect relationship findings, "Implementation of IoT applications" and "Economic" factors were found to be mostly influenced, while "Applicability of IoT throughout the supply chain" and "Technical" factors were recognized as the most influential. The results of this research can guide food producers and technology policymakers in their supply chains and help avoid trial and error in IoT implementation by leveraging global and national experiences.

INTRODUCTION: Considering the high number of incidents and disasters in Iran and the importance of the issue, this research investigates the challenges and opportunities of people's participation in the implementation of disaster management policies in the Iranian Red Crescent Society (IRCS). METHOD: The research is applied in terms of purpose and mixed in terms of method. In the first stage, structured interviews were conducted with 20 experts and informants in the field of disaster management. Then, data was analyzed through content analysis and open coding, and components of challenges and opportunities were extracted using Maxquda software. Finally, a researcher-made questionnaire for challenges and opportunities based on the findings of the qualitative part was design and its validity and reliability using was confirmed by experts and Cronbach's alpha respectively and were distributed among 365 managers and employees related to disasters. FINDINGS: According to the findings, in the qualitative section, the main challenges include coordination and organization, lack of people’s participation in decision-making, conflict of interests, participation sustainability, level of knowledge and awareness, and resistance to change, as well as the opportunities include increasing efficiency and effectiveness, the use of local knowledge, strengthening the sense of responsibility, communication improvement, cost reduction and strengthening social solidarity. The results of quantitative part, showed that strengthening the sense of responsibility, use of local knowledge and communication improvement with an average of 11.86%, 10.38% and 9.46% respectively of the most important opportunities and conflicts of interest, the level of knowledge and awareness and coordination and organization with an average of 10.43%, 9.37% and 9.35% respectively are the most important challenges. CONCULSION: The results showed that solving the challenges and strengthening the opportunities for people's participation will lead to the success and effectiveness of the implementation of the policies and will lead the society to the direction of prosperity, prevention of wastage of resources, casualties’ reduction and sustainable development. Thus, it is suggested to develop educational programs, strengthen organizational structures, etc. in order to improve people's participation in disaster management.
