Materials are the most noticeable components of every language-learning context. One of these materials is the specific textbooks being used by English language academies; they are crucial in directing EFL teachers and learners and guiding them through the route of language learning. The present study attempts to compare the cultural content of two course books being used currently in Iran called ILI and Rise and Shine series in order to see which one is more useful in developing the intercultural competence of EFL learners. The participants of this study include 30 EFL teachers (15 teachers in ILI who teach advanced level books and 15 teachers in Chitsazan academy who teach advanced level books). The instrument of this study includes a questionnaire adapted from (Ahmadi Safa, Moradi et al. 2015) that consists of 38 questions designed based on Likert scale. The collected date were analyzed by an independent t-test. The obtained results revealed that Rise and Shine series include more intercultural features than ILI series and they are more applicable in improving the intercultural competence of EFL learners.

Achieving the goals of educational systems and responding correctly to the expectations of students, parents and teachers depend on the existence of efficient and effective educational administrators and their beliefs. Therefore, the attention of education researchers is focused on the understanding of management in educational settings. Since individuals' beliefs cause the creation of personality structures, so the study of managers' personality structures can be helpful in selecting, transferring and relocating educational managers on a scientific basis, recognizing the necessary components of management to establish training courses, predicting future actions of managers and reducing skepticism and uncertainty and identifying the stylistic complexity of managers. On the other hand, structures enable educational administrators to better fulfill their professional mission. Based on the importance of this issue, the main purpose of the study was to identify and compare the personal structures of management among school principals. In the present study, in order to achieve the personal construct of managers, an interpretive approach and a qualitative method of case study were used. Participants included all public school principals in Sanandaj who were employed in 2021 and had more than one year of managerial experience. Therefore, sampling was done in a target based using the criterion method. Also, the number of samples was appropriate for the Repertory Grid Technique which is usually used for the sample with small number, 43 novice and experienced Principal were chosen. Data were collected using semi-structured interviews and a Repertory Grid Matrix. Finally, 575 personal construct were extracted during 43 interviews. Content analysis with the unit of subject was applied for the data analysis. The collected data of the personal construct of administrator were classified in 4 main categories and 13 sub-categories, which included issues as morality, relationship, personal features and intellectual-functional. The results of this study indicates that the highest percentage of personal constructs of novice and experienced managers is in the category of communication and the lowest percentage of personal structures for novice managers is in the category of intellectual-operational and also for experienced managers is in the category of ethics.

Vicinity in its various dimensions (Geographical, Political, cultural and etc ) has Fundamental importance in convergence and common understanding of the political units. This factor led to Convergence and sustainable security in various aspects of economic, socio-cultural and environmental . Therefore, Health infrastructure, cultural heritage, economic interests and ... have important from the perspective of Geopolitical tourism . Accordingly, this study has raised the question that is the geographic proximities such as Geographical neighbors, Identity – historical, Common cultural heritage, Health, environmental problems, economic interests, political and etc, in relation to Iran and Azarbayejan (Geopolitical tourism) of the two countries can be resulted in sustainable convergence and security. Explaining the question has been done by the Analytical - Descriptive method and the collection of Data and Information have been done by library study . The results show that in the world of highly evolved, that threats Show themselves In newer dimensions day by day, Geopolitical Tourism can determine the convergence And common understanding between political units - Space of geopolitical contexts. In the meantime, whatever this proximities more and deeper, Tourism geopolitical power as a parameter in the field of convergence and convergence of political - space units - would be more practical. Since the two countries of Iran and Azerbaijan have a variety of cultural, social, environmental, economic interests, etc proximities, Geopolitical Tourism can provide the contexts of shared understanding and the convergence between the two countries.

Wireless sensor networks (WSNs) are the sensor nodes that are generally interconnected and these nodes communicate wirelessly to collect the data from the environment around them. Sensor nodes are low-powered and distributed in a decentralized ADHOC manner. WSNs setup comes with some limitations such as energy constraints and the cooperative demands essential to perform multi-hop geographic routing for Internet of things (IoT) applications. Quality of Service (QoS) depends to a great extent on offering participating nodes an incentive for collaborating. The real-time applications of WSNs have potential design limitations such as energy and other QoS constraints in the context of IoT. This work formulates two different re-transmission strategies for optimized cross-layer design and also integrates the framework with a swarm intelligence technique assisted Bacteria Foraging Optimization (BFO) for efficient Cluster Head (CH) selection. The proposed work designs analytical modelling to realize the formulated concept and also simulates the computational design in a numerical computing tool. Finally, an extensive simulation is carried out using the MATLAB simulation tool. The obtained results show the effectiveness of the proposed system in terms of delay is reduced by 12%, throughput is increased to 10%, remaining energy of the network is increased to 11%, and packet delivery ratio of the proposed work in increased to 7-9% in comparison with the existing system.
