Abstract
Statecraft, or what is called modern politics in the Shahnameh, has prosperity and authenticity combined with knowledge and insight. The foundation of Shahriari and governance is based on the two principles of truth and justice. Ferdowsi′s Shahnameh is one of the greatest and most influential epics works of Iran and the world. This great work can be studied and researched from different aspects. In many stories of Shahnameh, a manifestation of positive psychology can be explored.
One of the most outstanding literary works in the field of Persian literature is Ferdowsi's Shahnameh, which contains characterisations, depictions of lofty and ideal human goals, references to desirable solutions to improve the quality of life, and so on. In his literary masterpiece, Ferdowsi has mentioned the human being and its positive dimensions, and has provided extensive explanations in relation to idealistic figures such as Ky Khosrow - who go beyond the usual norms of society. In this regard, the present research, by applying Seligman's psychological opinions, will examine and analyse other aspects of Shah Kiani's personality and Shahriari's and Pahlavi's actions in order to answer the following questions: a) Which of the characteristics of positivist psychology emphasised by Seligman are prominent in the character of Khosrow? b) By approaching Seligman's intellectual foundations, can Shah Kiani be considered a positive and self-fulfilling person?

Abstract
- Each nation has its origins in the manifestation of the beliefs and customs of its people. Literature is the mirror par excellence of each nation's past. The history of each nation or people is not discontinuous and, if a message of a text of folk literature is related to its historical realities, it will always be transmitted over time to the following periods and will be periodically reconstructed. One Thousand and One Nights- the prototype of world’s tale- has been always a remarkable source in folk literature. Throughout the history and over time, these stories have been emerged under diverse meanings and shapes. Farīd ud-Dīn Attār, the mystic poet- has taken the advantages of folk literature in order to express mystic thoughts. The existence of common signs and points as well as formal and content aspects of these tales show the inter-textual relations of both histories. It is possible to describe structural pattern of these stories by investigating their lyric structure. According to their theme, stories have different content (epic, romantic and mystic). In this research, the authors have compared two histories from Elahi-Nāmeh and One Thousand and One Nights according to Gérard Genette theoretical framework and inter textual relation by insisting on the their impressionability from folk literature.

Abstract
This paper aims to measure the extent of mark-up and monopoly pricing in different sub sectors of the Iranian manufacturing. We measure annually the degree of monopoly pricing and mark-up for sub sectors over the period from 1959 to 2003. A panel data approach is developed and applied to gauge the mark-up and degree of monopoly pricing
The results show that in four sub sectors, including chemical, non-ferrous metals, basic metals and machinery, these kinds of pricing are dominated and it is also prevalent in other sub sectors. Capital intensity and increase in the number of firms in each sector cause a reduction in mark-up while trade liberalization leads to an increase in productivity. The experience of liberalization in Iran over a short period of time confirms that mark-up is reduced, productivity is increased and capital intensity is decreased.

Abstract
This paper aims to evaluate the relationship between exports diversification and productivity for nine Iranian manufacturing industries using a panel data approach. Empirical results indicate that productivity and exports have similar trends over the period considered in this study. Indicators such as capital-labor ratio in sub-sectors of the manufacturing and the real effective exchange rate have positive effects on productivity. Exports diversity index has also a positive and significant impact on productivity such that one percentage change in this index increases productivity by 1.8 percent. The effect of trade liberalization on manufacturing productivity is negative and negligible, implying that, to promote productivity, policymakers should consider other fundamental and institutional factors in addition to the foreign trade.

Abstract
Aims: This research aimed to evaluate some phytochemical characteristics of Clematis ispahanica Boiss. in two arid and semi-arid sites.
Materials & Methods: After studying the climatic conditions in each site, 30plots (6m2) were established randomly– systematically for soil and plant sampling. A total of ten composite soil samples were collected from two depths (0–10 and 10-30 cm), and some of their properties were measured. Three plant samples were obtained and mixed at three Phenological stages in each site, and their secondary metabolites were determined. A comparison of soil properties between the two sites was performed using an independent-sample t-test. Phytochemical comparison of plants between two sites and three Phenological stages was performed using Factorial analysis of variance and Duncan’s multiple range test. Correlation between soil properties and phytochemical characteristics was performed using the Pearson correlation coefficient.
Findings: The results demonstrated that C. ispahanica has higher secondary metabolites (total Phenol, total Flavonoid, and total Alkaloids) in semi–arid climates compared to arid climates. In both sites, the highest content of secondary metabolites was observed at the flowering stage (Phenolic content in Bavanat and Mehriz city’s 184.33 & 115.16 mg GAE.g. DW Ext, Flavonoid content, 32.57 & 28.37 mg QE.g DW Ext, Alkaloids content 12.89 & 5.75 mg Atr.g DW Ext, respectively). A significant, mostly positive, correlation was observed between the phytochemical characteristics of C. ispahanica and soil pH, EC, and total Nitrogen.
Conclusion: It was concluded that heavier soil texture, semi-arid climate, and flowering stage are more suitable for C. ispahanica secondary metabolites production.

Abstract
Aims: This research examined climate change’s impact on the Eurasian otter’s habitat (Lutra lutra) in Khuzestan Province based on habitat modeling in R regarding climate scenarios and the MRI-ESM2-0 general circulation model.
Materials & Methods: 72 points were recorded, and ten climatic and environmental variables were used as inputs for the models. The ROC curve, TSS, and Kappa coefficient were used to assess model accuracy using three different methods.
Findings: In the ROC model, AUC 0.7–0.8 indicates a suitable model, AUC 0.8–0.9 indicates a robust model, and AUC > 0.9 indicates a powerful model. In the TSS model,> 0.75 indicates excellent diagnostic power, 0.4–0.75 indicates good, and < 0.4 indicates weak diagnostic power. The Kappa coefficient (0.39–0.98) shows good prediction accuracy. The RF and GBM were the best for determining the habitat of the Eurasian otter in Khuzestan Province. River distance, BIO1, and BIO3 had the most significant role in habitat suitability. A total of 9176.185 km² of Khuzestan Province was identified as a suitable habitat. The prediction of the species’ distribution changes based on SSP126, SSP370, and SSP585 showed that this species’ habitat would decrease until 2070.
Conclusion: Climate change significantly affects the distribution of the Eurasian otter. Similar to other studies on animal and plant species, it leads to habitat reduction and alterations in habitat ranges.
