Abstract

Urbanization and the increase in urban populations, resulting from both natural population growth and rural-to-urban migration, have led to the concentration of significant material and spiritual human capital within urban settlements. Concurrently, various natural and human-induced crises pose threats to these capitals. Urban management has initiated a range of programs to address these crises, with a contemporary focus on enhancing the resilience of cities. The concept of resilience can be examined across various dimensions, including physical, economic, social, and environmental aspects.
The present study adopts a descriptive-analytical approach with the objective of assessing the physical resilience of metropolitan areas in Tabriz and determining their status relative to one another. To achieve this goal, multi-criteria decision-making methods (MADM) and the Analytic Hierarchy Process (AHP) have been employed. Additionally, three models—Technique for Order Preference by Similarity to Ideal Solution (TOPSIS), VIKOR, and Complex Proportional Assessment (COPRAS)—have been utilized to rank the regions in terms of physical resilience. Ultimately, the Copeland model was applied to integrate the results from the aforementioned models. The findings indicate that regions 2, 8, and 9 collectively exhibit the highest levels of physical resilience, followed by regions 1, 10, 3, 7, 5, 4, and, lastly, region 6, respectively.

Abstract

Atmospheric rivers are one of the atmospheric phenomena that generate heavy rainfall and can lead to significant human and financial losses. Understanding the synoptic mechanisms of water vapor flux and atmospheric river formation in the country's atmosphere, as well as revealing the interaction between the NAO (North Atlantic Oscillation) zonal component and the creation and intensification of this atmospheric phenomenon, can greatly improve the predictability of torrential rainfall events. The main goal of this research is to investigate the atmospheric river phenomenon in the Iranian atmosphere and its relationship with the phases of the NAO phenomenon. In this regard, data on the zonal and meridional components of wind, specific humidity, and NAO anomalies were obtained from the NOAA database during the statistical period of 1944–2019. The results showed that during the study period, atmospheric rivers have shifted in terms of longitude and latitude, moving toward the southern half of Iran. A high correlation was observed between the NAO index and meridional flows at levels above 600 hectopascals. Additionally, a sigma value of 0.2101 indicated a strong correlation with the NAO in the area where atmospheric rivers enter the Iranian atmosphere.  High-pressure centers play an important role in directing atmospheric rivers. These rivers cannot pass through high-pressure centers and typically exhibit meridional curvature at the outer borders of these centers in the Northern Hemisphere, resulting in southwest and northeast orientations. The primary moisture source for atmospheric rivers entering Iran is the Atlantic Ocean, which is further enhanced by water bodies such as the Red Sea, the Sea of Oman, the Indian Ocean, and the Persian Gulf.

Abstract

The objective of this study was to examine the impact of destination image and service quality on the competitiveness of tourism destinations, specifically focusing on Tabriz city. This research is classified as applied in terms of its purpose and analytical in terms of its descriptive methodology. The statistical population comprised incoming tourists to Tabriz, with a sample size estimated at 384, calculated using Cochran's formula for an infinite population. To gather field data, a researcher-developed questionnaire was employed, the validity of which was confirmed by subject matter experts. The reliability of the instrument was assessed using Cronbach's alpha and composite reliability, with the results affirming the questionnaire's reliability. Data analysis was conducted utilizing SPSS and LISREL software. The findings indicated that both destination image and service quality exert a positive and significant influence on the competitiveness of tourism destinations. Furthermore, the path coefficient analysis demonstrated that the impact of destination image on the competitiveness of tourism destinations was greater than that of service quality.
