Abstract Background and Objective: Parking management is one of the most important instruments of urban transportation management. Appropriate parking pricing policies can significantly influence traffic efficiency, travel behavior, and urban quality of life. Among transportation demand management strategies, urban network pricing has been recognized as an effective mechanism for addressing two major urban transportation challenges, namely traffic congestion and environmental pollution. In this context, parking pricing can be employed as an economic tool to regulate parking demand, reduce cruising traffic, improve network performance, and optimize the utilization of limited urban land resources. This study aims to determine optimal parking prices for selected parking facilities in District 5 of Isfahan City by employing a mathematical programming framework based on Nash equilibrium. The proposed model minimizes total network costs while accounting for the equilibrium behavior of drivers in their parking location choices.
Methodology: The analytical framework assumes that travelers select parking facilities by minimizing their generalized travel costs, which consist of driving costs, parking fees, parking search time costs, and walking costs from parking locations to final destinations. Given fixed parking locations and travel destinations, optimal parking prices are determined through a network cost minimization problem under equilibrium conditions. The empirical analysis focuses on District 5 of Isfahan City. The study network consists of five origins (Tohid, Pole Felezi, Pole Azar, Hakim Nezami, and Mohtasham–Shariati), three major destinations (Hakim Nezami, Nazar, and Jolfa), and three public parking facilities (Tohid, Khaghani, and Jolfa). Traffic and parking demand data were analyzed over eight hourly periods. The optimization model was solved for each time period to estimate optimal parking prices and occupancy levels.
Results and findings: The results reveal significant temporal variations in optimal parking prices across the selected facilities. The average optimal parking fees were estimated at 7,040 Tomans for Tohid Parking, 8,520 Tomans for Jolfa Parking, and 9,140 Tomans for Khaghani Parking. Furthermore, the estimated optimal parking capacities indicate that Tohid Parking accommodates the highest average occupancy level with 308 parking spaces, followed by Khaghani Parking with 281 spaces and Jolfa Parking with 88 spaces. The findings also demonstrate a positive relationship between optimal parking prices and parking occupancy levels, suggesting relatively inelastic parking demand within the study area. This behavior can be attributed to the concentration of commercial, service, and recreational activities in District 5, which generates a stable demand for parking facilities despite changes in parking fees. The analysis further shows that parking occupancy closely follows traffic volume fluctuations throughout the day. As traffic demand increases during peak periods, parking utilization rises correspondingly, while reductions in traffic volumes are associated with lower parking occupancy rates. This finding highlights the strong interdependence between parking demand and urban traffic conditions.

Abstract Background and Objective: Human resources, as the most important and valuable resource, play a significant role in the success of an organization because the organization's human resources have the ability to change their performance and are considered the main tool for achieving organizational goals. Today, the success of organizations requires more attention to human resources. In order to succeed, organizations must make good use of their human resources capabilities, and in this regard, paying attention to organizational citizenship behavior is of particular importance. Therefore, in today's world, having employees who go beyond their roles and duties and demonstrate organizational citizenship behavior is a prerequisite for the success of organizations. Therefore, the present study was conducted with the aim of the effect of organizational citizenship behavior on employee performance in the hotel industry at Abbasi Hotel in Isfahan.

Also, structural equation modeling using Smart PLS software was used to analyze the data.
Results and Findings: The results indicate that organizational citizenship behavior and each of its dimensions have a positive and significant effect on employee performance. It was also shown that the work conscientiousness variable has the largest path coefficient value and its effect on employee performance is greater than that of other variables.

Abstract Background and Objective: This research presents a comparative study of the historical bridges of Ardabil and Isfahan during the Safavid era, focusing on the influence of each region’s geographical features on the architecture and construction of these bridges. During the Safavid period, both Ardabil and Isfahan were recognized as significant political, cultural, and economic centers of Iran. Bridges of this era, beyond their function as crossings, played a crucial role in enhancing communication, facilitating economic exchanges, and even serving military purposes. The design and construction of these bridges were influenced by geographical, climatic, topographic conditions, and available local resources. In this context, examining how architects and engineers responded to natural challenges reveals the degree of architectural adaptation to the environmental context. The findings of the study indicate that geographical differences have led to variations in the design, construction, and functions of the bridges. Bridges in Ardabil, suited to mountainous conditions and variable rivers, exhibit more robust structures, while bridges in Isfahan, influenced by the urban setting and the Zayandeh Roud River, feature more open, decorative designs with multifunctional roles.
Methodology: The research methodology is descriptive-analytical, and data has been collected through library sources, historical texts, architectural documents, and geographical analyses. The core of this analysis consists of a comparison of design, structural types, materials used, and the functions of the bridges.
Findings and Conclusion:  The main objective of this study is to compare the architecture and structure of prominent historical bridges in Ardabil and Isfahan and to analyze the impact of geographical factors such as climate, topography, and water resources on the formation of their form, materials, and functions. This research aims to identify architectural patterns adapted to environmental conditions through the study of selected examples.

Abstract Urban decayed texture is the most important potential for using urban land, for housing, providing open spaces and services, and improving the environmental qualities. On the other hand, these contexts are a practical solution to prevent the physical expansion of the city from underdeveloped lands around the city and the development of empty and abandoned lands within the urban area that can help revitalize  the city. In this regard, the main aim of this study is to identify the capacity of decayed texture to construct housing. Research method is descriptive-analytical in terms of nature, and applied in terms of purpose and aim. In order to achieve the goals of the research, spatial data and performing relevant analyzes in GIS and multi-criteria decision model AHP, VIKOR, SAW has been used. The statistical population were urban planning experts of Isfahan, and the sample size is 30 experts, based on theoretical saturation, and snowball sampling is used to choose the experts. The results of the two methods of VIKOR and linear weight combination showed that out of the total area of ​​Sarcheshmeh neighborhood, in VIKOR model 336354.29 square meters and in linear weight combination model, 15213.59 square meters have high capacity for housing production. Since the number of pixels on the utility threshold is higher in the VIKOR model, the output of the VIKOR model is preferred to use the decayed texture to provide future housing.

Abstract Today, planners believe that environmental quality is a key concept for regional and social planning and is associated with concepts such as quality of life, diversity of social space, physical characteristics, activities, spatial dependencies, and urban identity. Therefore, improving the quality of the environment has become one of the main goals of policy makers and urban planners. The purpose of this study is to investigate the importance of environmental quality components from the perspective of tourists in Isfahan metropolis. The research method in this study is descriptive-analytical and the data are prepared by survey method. The statistical population of this study includes tourists of Isfahan metropolis, which using a Cochran''s formula, a sample of 384 people was randomly selected and studied. This number was questioned through a questionnaire whose validity was tested using Cronbach''s alpha method. In this study, in order to analyze the data, the statistical approach of structural equation modeling (SEM) and the second-order five-factor confirmatory factor analysis test were used. The final results obtained from the elimination of the effects of measurement errors in the structural equation modeling approach, indicate the effectiveness of the evaluation of the tourist community of environmental quality, respectively, environmental, aesthetic and formal, semantic and perceptual dimensions, and finally functional and activity.
