The COVID-19 pandemic has necessitated a rapid shift to online learning, making the community of inquiry (COI) framework increasingly relevant for creating meaningful and effective online learning experiences. However, the impact of COI presences (i.e., teaching, social, and cognitive presence) on students' learning outcomes has been inconsistent in the literature, and a recent meta-analysis has identified a publication bias in this relationship suggesting the need for further investigation. This study aimed to enhance our understanding of how the COI presence influences college students' learning outcomes and whether it has a mediating role in the effect of self-efficacy and motivation on e-learner’s academic achievement. In this cross-sectional study, using a correlational research design, among all graduate students studying in online courses, a total of 269 graduate students were selected from online programs in seven public universities in Iran between April 2022 and June 2023, to be the sample of the study. The data were obtained from the answers to the community of inquiry (COI) scale, self- efficacy scale, academic motivation scale and students’ last semester grade point average. To examine the questions of the study, a path analysis was applied whose results showed that motivation and self-efficacy affected the community of inquiry positively (p<0.000). Also, the community of inquiry affected learning performance positively (p<0.000). The outcomes can provide significant theoretical and practical contributions to the key stakeholders to design a satisfying and successful online curriculum for the post-COVID-19 era and offer valuable insights into the design of productive online learning communities.

Purpose - The rural-urban integration refers to an optimal combination of natural, economic, social, and spatial factors. The scale of this integration depends on the extent to which urban and rural systems (economic, social, and environmental) influence, interconnect, complement, and share benefits. The main goal of this study is the environmental analysis of villages in the periphery of Farsan city based on the rural-urban relationship. Design/methodology/approach- This is an applied study that uses a descriptive-analytical method. Data were collected using a questionnaire. The statistical population of the study consists of the four villages in Farsan county with a population of over one thousand people. Together, these four villages are home to about 4285 households (14972 people) from which a sample of n=375 was selected using Cochran's formula. Finding - The results of the research based on the one-sample t-test indicate an environmental relationship between Farsan county and its nearby villages. The environmental indicators such as noise pollution and non-expansion of green space, the change of cultivation pattern, the intensified land abuse and brokerage, the reduced share of water in agriculture, and the limited environmental knowledge of villagers suggested adverse effects whereas other variables manifested the positive effects of the connection with Farsan on improving the environment of the nearby villages. The results of regression analysis showed that the environmental relationship of Farsan with its surrounding villages explained 17% of study indices (environmental health, land-use change, water and soil resources, knowledge and importance of environmental issues) and the remaining 83% was explained by other factors not addressed in this study. Research limitations/implications - The main limitation of the study was the scant literature on the environmental effects of the urban-rural relationship. Practical implications - Implementing a suitable cultivation model for agricultural products, expanding new irrigation systems, maintaining and reviving orchards, and raising awareness of environmental issues among villagers should be put on the agenda. Originality/value - Investigating environmental effects of the urban-rural relationship as a way of ensuring sustainable rural settlement and environmental protection in the study area.

Tourism and the related economy is transforming and plays a vital role in world economy. Many economic development planners and policymakers also refer to tourism industry as the basis for development. Tourism-related activities and the provision of appropriate services in an area, like many other economic sectors, require necessary groundings in terms of its origin. Therefore, based on the importance of tourism industry on the one hand, and the existence of tourism potentials of Tehran province on the other hand, an appropriate procedure is required for prioritizing different areas in the province in order to efficiently and appropriately plan and prioritize different investments in these areas. In this regard, the aim of this research is to evaluate of tourism development indicators of Milad Telecommunication tower. In order to analyze the research data, the CO-PLOT analysis method and comparative comparison of Milad Tower tourism statistics were used. The results of factor analysis indicate the importance of the managerial-institutional dimension as one of the important factors in the tourism development of Milad Tower; the results from a t-test showed that the effect of each factor and dimensions is different on tourism development of Milad Tower. According to the tourism experts and professionals, the institutional-managerial, political, physical, socio-cultural, economic factors are of paramount importance in the tourism development of Milad Tower.
