Textbooks play a crucial role in English language teaching and learning. One of the methods for selecting the most appropriate textbook for a particular educational purpose is comparing two or several similar textbooks with each other. Textbook evaluation can provide useful information about the strengths and weaknesses of textbooks and can lead to the selection of the most suitable materials for specific purposes. The present study is a critical comparison of Prospect 2, taught in junior high schools in Iran, and English Net 6, taught in junior high schools in Turkey, in terms of their physical and utilitarian attributes, efficient outlay of objectives and supplementary materials, learning and teaching contents, and language skills. The participants of the study were 20 English teachers who completed two evaluation checklists. The textbook evaluation checklist that was used in the study was based on the guidelines and framework of AbdelWahab’s checklist (2013)with 123 items. The results of the study indicated that the Turkish textbook surpassed the Iranian one in many aspects of the text book evaluation checklist. The results revealed that in comparison with English Net 6, Prospect 2 had more weaknesses in terms of physical and utilitarian attributes, efficient outlay of objectives and supplementary materials, learning and teaching contents, and language skills.

Purpose: The examination, investigating and relationship between costs, benefit and attachment to the environment by mediating behavioral attitudes among sports tourists. Method: The population of the study consisted of all sports spectators of 27th Fajr Open and Esteghlal vs. Tractor rematch from 15th Persian Gulf Pro League. According to Kukran formula sample size was equal to 722 persons. 920 questionnaires distributed among population that 722 questionnaires were analyzed. In order to collect data a self-made questionnaire was used which it's validity confirmed by 5 sports teachers of Razi and Tehran university and variables reliability was calculated by using Cronbach's alpha coefficient which was equal to 0.89. Data analysis done by using the descriptive and inferential statistics include Kolmogorov–Smirnov, Pearson correlation, path analysis of structural equations, Regression and also AMOS-21 and SPSS-22. The results showed that environmental communication should be formed within the right framework, encourage people to Environmentally Responsible Behavior through a bonus is not necessarily effective and doesn't encourage sports spectator. Results: Result showed that spectators display more cooperation through targeting for enjoyment and are sensitive toward any perceived cost in the implementation of Environmentally Responsible Behavior. The result also showed if cooperation with Environmental Management System doesn't take too much time and totally doesn't interfere with their enjoyment of watching match, they will support it automatically. The results also suggest the need to design efficient equipment to ensure ease of use and as a result reducing the perceived cost associated with Environmentally Responsible Behavior. Conclusions: Sports event owners can encourage spectators to do the Environmentally Responsible Behavior by connecting with them and also induce this fact to spectators that associate with the event can assist them to experience higher quality events in the future.

Due to the importance of public transportation, which has become today an important urban problem with special conditions, this study was conducted aimed at determining the parameters affecting the mathematical programming model of the appropriate transportation system. The study was performed by modeling method, and the problem was solved in three different sizes (small, medium and large) to show the efficiency of the model and the proposed solution methods. Some common test problems in the literature were selected and the required characteristics of the problem under study were defined for them as needed, since there are no sample test problems in the literature to examine the performance of the developed algorithms. The results indicated that some of the most important parameters affecting the designed mathematical model were movement risks, fatigue and drowsiness while driving, demands at the source node, demands at the destination node, number of vehicles across the network, the time interval between requests, and the time interval between two consecutive requests. The mentioned parameters were so effective that little changes in parameters such as demands at the source node, demands at the destination node, and the number of vehicles across the network significantly increased time and decreased profitability. the company has a significant effect on the debt cost rate and capital cost rate and does not have a significant effect on stock prices. Finally, the share price shows little sensitivity to the company's financial structure.
