INTRODUCTION: After the approval of the country's crisis management law, the upstream documents related to this law, including the preparedness and response programs at the national and provincial levels, are among the tasks assigned to increase the efficiency of the crisis management processes. METHODS: This study presents a general framework for developing a provincial crisis response program. The proposed process has been used to develop the crisis response program of Hamadan province. In the phase of understanding the current situation, questionnaires and in-depth interviews were used to collect field data and determine the challenges presented to crisis management in Hamadan province. Moreover, a method for allocating the specialized functions of the response phase to the provincial organizations has been presented using the national crisis documents. FINDINGS: In general, the findings of this research can be assigned to three groups. The first group pertained to the project method, including the stages of understanding the current situation and developing the response program of the provinces. The second group of findings was the summary of the analysis of field data collected regarding the state of preparedness and response in Hamadan province. The third group encompassed determining and allocating specialized crisis response functions in Hamadan province. The functions of the provinces (n=32) and after their compliance with the national functions, the crisis management law, and the capabilities of the existing organization in the province, 56 specialized sub-functions were identified in the provinces, and the responsible, collaborating, and supporting institutions were determined. CONCLUSION: As evidenced by the obtained results, in the process of function allocation, some problems have been identified due to the shortage of information in the upstream documents, which are suggested to the crisis management organization for better planning.

Online learning has recently turned to one of the most well-known channels of education; however, the controversy over the quality and outcome of such online medium is still a concern. This study sought to determine the pros and cons of online courses as perceived by Iranian language teachers and learners. Two tailor-made questionnaires, along with a semi-structured interview, were used to collect the data. The participants were 71 college students who have experienced online educations and 31 language teachers who taught web-based classes in the Department of English Language Education at three universities in Iran, Isfahan, Sheikhbahaee, and Ashrafi. An overall analysis of questionnaires and interviews revealed that students and teachers could not find online education easier than its conventional counterpart. Online education provides teachers with a precise image of applying the appropriate teaching methodology in their online classes as well as enhancing their autonomy. The research recapped that online educators and administrators of faculties ought to lay the foundations for making the benefits of online education bold for learners. The findings may be a contributing factor for teacher educators to create the climate for professional development.

This study examines the relationship between stock liquidity and return predicta-bility of 116 publicly-traded firms in Tehran Stock Exchange (TSE). To this end, we constructed a dated-regular frequency of time series with total 40128 stock-firm observations. After calculating daily bid-ask spreads and stock returns, the observations were classified based on liquidity into three classes and the return predictability was investigated across different classes using a set of parametric tests. The results exhibit signs of return autocorrelation and non-independence over three liquidity groups. Our findings didn’t show a connection between stock liquidity and market efficiency. The Hurst exponent also revealed mean reversion of returns series across different liquidity classes. We conclude that stock liquidity doesn’t play a significant role in market efficiency and return predictability of stocks in TSE. In case of TSE as other emerging markets, due to the small num-ber of traders (the need for more trading activity) and low market making activi-ties, both the cost of trading increases and the reaction to stock price information is delayed, resulting in predictability of price /return.
