Introduction
Although more than half a century has passed since the academic birth of urban design, it still suffers from ambiguities in theory and practice. Questions emerge such as the following. Can urban design be a definite discipline? Is urban design independent of urban planning, architecture, and landscape architecture? What is the role of urban design in the real world, and what is the final product? What is the appropriate process and the main toolboxes? Answers to these questions must be part of the common discourse of the field, definite answers to clarify all the ambiguities.
Theoretical Frameworks
Despite these ambiguities, urban design continues to be considered as an intellectual tradition. It plays a significant role in everyday human life, and remains a subject matter in many studies. In recent years, many urban projects have sought to create noble environments for people while providing economic benefits for the private sector and local governments. Some research has attempted to evaluate such projects. The results point to the fact that many such projects have failed to accomplish their stated goals. Theoretically, this appears to be the result of a theory-practice dichotomy.
However, there has been a gap in comprehensive research since the 1990s on the urban design process. Although several different parameters affect the implementation of designed projects, the urban design process may play a significant role in the end product. Hence, the question is what could be the relationship between the urban design process and on-the-ground project realization? A complementary question is whether we can manipulate the urban design process to achieve the stated design goals and realize the projects as intended. To answer these questions, we first present a literature review on the urban design process and then discuss the results of our examination of some implemented projects to find clues about how to handle the urban design process and solve the theory-practice dichotomy of urban design itself.
Urban design ambiguities can influence the urban design process as its central procedural dimension, which has implemented projects as its results. Although different parameters cooperate to make it troublesome to utilize a project, all designs are affected by the urban design process. Thus, the question concerns the relationship between the urban design process and project realization. It is also unknown whether we can manipulate the urban design process to ensure the realization of projects. In addition, based on the theory-practice dichotomy, we need to know whether the evaluation of urban design projects and their realization can give us a clue as to how to handle the urban design process. Therefore, we attempt to resolve theoretical ambiguity in urban design by examining some real-world projects. Here, we assume that the urban design process can also transfer theoretical ambiguities to real-world practice as a medium that canalizes theoretical knowledge to practice.
Methodology
The research addresses many unknown topics and undefined parameters. Thus, it may not be possible to develop a specific theoretical framework with a clear list of measurable criteria to meet the research goals through a classified research method. Our literature review leads to a framework that points to a relationship between the subject matters. This framework is not exhaustive because our research does not rely on quantitative measurements and focuses on experience with the subject.
Therefore, the study is restricted to qualitative research. Due to the uncertainties about the topics, a theoretical interpretation is made of the literature based on qualitative research to develop a framework for an experimental approach to the issue. Content analysis and action research lead us to calibration of the framework. The result provides an ultimate configuration for a practical framework which can be an a priori model which can be calibrated to an ultimate model by experience. Such an experience clarifies the parameters and their relationships through direct contact with the research domain. Therefore, a model is created for the urban design process after the literature review, applicable to examination of operational experience. Finally, we observe that the process is not an ultimate one but can help us find an ultimate one based on the iteration of the a priori model.
Here, the case study addresses the master plan for the Abbasabad region in Tehran. We use this project as the subject of our content analysis. The project is examined through the documents, i.e., reports, administrative correspondences, and proceedings, based on the meetings of cultural and technical committees.
The documents are analysed in MaxQda. The keywords used in the software include project, realization, process, ratification, Article 5 Commission, master plan, specific plan, implementation, and construction. After the first search in the documents, the useless words are eliminated, and the search is carried out again for their classification. The results are analyzed interpretively. Next, another project–i.e., design of the southern Kan area–is used as a case study implemented on the ground.
Results and discussion
The generalization of the incremental process can be explained theoretically, but the experimental proof requires more cases and several, repeated experimental applications of the process. Practical application of the process can calibrate the framework to a more realistic one. The result of the theoretical explanation is that the general format of the process can change over time to turn to a complete model, other models, or derivations of the present model.
In fact, a model is generated after the literature review calibration of which through experimental research leads to a design process.
Conclusion
The incremental process, as proposed in this paper, needs to be tested over time. The relationship between practice and implementation can be recognized through direct experimentation with the incremental process. However, the relationship between implementation and theory (following that between theory and practice) can be recognized through research methods such as design studies. This can demonstrate how theoretical knowledge can be converted to the practical material of projects.

Introduction
Because of the expansion of cities, it has become highly challenging to modify urban structures to address the drawbacks of the planning and design of open spaces, control microclimates, and improve thermal comfort conditions. Due to their effect on the quality of air in cities, urban microclimates are highly significant, and since urban spaces play an important role in creation of urban microclimates, urban designers and planners have the capacity and means to reduce the negative effects of climate on citizens’ health through implementation of proper designs.
Theoretical Framework
Urban spaces affect their users’ thermal comfort via their design elements. Various parameters can induce micro-climatic changes, such as the geometric patterns, vegetation, natural elements, and construction materials of the open spaces. These elements also play important roles in balancing urban thermal comfort during winter. While the effects of vegetation and geometric patterns on thermal comfort in public open spaces during winter have been studied independently, the cumulative impact of vegetation and geometric parameters during winter in cold and dry climates has not been investigated sufficiently. This article sought to address this shortcoming.
Methodology
The ENVI-met software was used for simulation and comparison of the thermal comfort conditions of the open spaces selected for this study. First, the design parameters of the selected sites were determined via field measurement, and were entered into the software for simulation of the thermal environments. The four climatic parameters of thermal comfort were measured during winter using ENVI-met . Then, a receptor was placed at the center of each selected site for investigation of thermal comfort at the pedestrian scale. Using these receptors, the parameters of space design and their impacts on thermal comfort were studied during the selected season.
Results and Discussion
The changes recorded for wind speed were larger than those in MRT, air temperature, and RH; hence, the differences in thermal comfort at the central points. According to the results, the Kolapa and Kolanj neighborhoods exhibited more favorable thermal conditions due to their higher PET values. Both Kalpa and Kolanj neighborhoods had north-south orientation. This type of orientation provides top-down access to the sunlight during winter. The H/W ratios at the central receptors of the Kolanj and Kalpa neighborhoods were 0.6 and 0.3, respectively. These H/W ratios provided greater enclosure than those of the other neighborhoods. While a H/W ratio less than one can be said to be suitable for cold climates during winter, it can cause thermal discomfort against wind speed if it lies below a certain threshold. This condition was observed in the Kababiyan neighborhood, where the H/W ratio at the central point was 0.13. As a result, the residents have to take protective measures against the winter wind and storms. In addition, dense vegetation caused a decrease in the SVF of the neighborhoods. The neighborhood centers with vegetation exhibited higher MRT values as well. The trees also raised the RH values of the neighborhoods. Because of the dry climate of Hamadan, Iran, vegetation can certainly improve thermal comfort in this city.
Conclusion
Recent climate studies have explored thermal comfort as an important quality of urban spaces. While thermal comfort can be achieved through a decrease in temperature in hot climates (as emphasized by most studies), it requires an increase temperature to provide thermal comfort in cold and dry climates. The presence of Hamadan’s citizens in the urban open spaces of the city always decreases in the second half of the year because of the cold mountainous climate. Limitation in or even lack of thermal comfort is one of the most important reasons for this change. With their high standards of sociability, the centers of the historical neighborhoods of Hamadan have always served as places for social interaction between the residents of the city. Therefore, this study attempted to assess the thermal characteristics of nine neighborhood centers in Hamadan using the notion of thermal comfort and the relevant variables.

Helping cities to attract skilled population, attract tourists and investors by relying on competitive advantages and identity
Urban branding is a process that helps cities increase the sense of belonging and satisfaction of current citizens.
the Use the capabilities of destinations to create creative attractions to attract tourists
Introduction
In the past few decades, branding has attracted plenty of attention in tourism planning. In globally competitive markets, the need of destinations to create a unique identity, that is, to differentiate themselves from competitors, has become more vital than ever. Tourism destination branding is a relatively new strategy in attraction of tourists because the brand gives the tourism destination identity and personality, and distinguishes it from other tourist destinations. According to the above, this study sought to address the role of the brand in the development of creative tourism and to help identify the city of Junqan, Iran as a brand using the city brand management (CBM) model. The research also attempted to specify the role and position of urban branding in the identification of the tourism in this city in terms of creativity.
Theoretical Framework
- Branding and urban branding
A brand is a rich source of emotional communication and cognition that leads to memorable experiences of a place such as a city. Urban branding is a relatively new concept that cities have adopted to differentiate themselves from other cities, to develop civic pride among their citizens, and to help tourists and business owners make decisions. Branding a city requires recognition of and information on the believable and realistic features of the city. That includes the historical, social, political, and international identity of the city, how it functions economically, and its amenities. Urban branding has turned into an essential topic in the field of tourism and a main factor affecting the tourism industry. Successful branding for cities and urban tourism destinations is based on their potentials and talents, so that the possibility of replacing it with other destinations is excluded.
- Creative tourism
Creative tourism means to travel to an original, exciting experience and to learn art, get to know the heritage or special features of the place, and establish a relationship between tourists and locals. A creative tourist develops their creativity capacity by approaching locals through informal participation in interactive workshops and learning the experiences that the destination culture plots for their vacation. In creative tourism, tourists engage in the cultural prospects of the destination, so that they can participate in various creative activities including agriculture, art, cooking, dance, and music. That creates new opportunities to learn new skills and establish closer relationships between tourists and locals and their cultural heritage.
Methodology
In the present applied, development-oriented research, a theoretical framework was first presented for the field of urban branding and creative tourism, and the role of urban branding in tourism was expressed using the methods of descriptive and library research for data collection. Then, the key factors influencing the generation of an image of Junqan and identification of its brand for development of creative tourism were studied using the city brand management model (CBM), the library method, and semi-structured interviews with urban and tourism experts. The interpretive analysis method was also used for analysis of the interviews.
Results and Discussion
The purpose of branding in tourism is to create and maintain a favorable image of the destination, increase tourists’ awareness, create positive attitudes toward the destination, and modify tourists’ behavior of visiting the destination. In addition to its positive economic aspects, the development of tourism in Iran can lead to a rapprochement between people of different nationalities. The study attempted to create a brand and manage it for the city of Junqan by examining the concepts of brand, urban brand, and creative tourism using the urban brand management model. The brand can help the city to enhance each of the indicators of creativity, leading to the development of creative tourism. The findings demonstrated that Sardar Asad Bakhtiari Castle was identified as the brand of the city of Junqan. For development of creative tourism aided by the city brand, a tourism route was provided that combined the historical and natural sights of the city to create innovative products and attract entrepreneurs who would find competitive advantages over other destinations. This could reflect the reputation and vision of the city around the world and support and guide creativity in the city, leading to the promotion of tourism, exports, and investment in the city.
Conclusion
We are currently facing the changing needs of tourists around the world, looking for new experiences and seeking to discover their talents. Urban branding is a strategy adopted to add a competitive advantage by providing a clear picture, cultural and political importance, and economic and social development. The main purpose of the discussion was to generate greater appeal for investment and to attract tourists and potential residents with an emphasis on community development and reconstruction of local identity in Junqan. Therefore, the achievement of the research could be addressed in terms of the dimensions of creative tourism. In the field of cultural development and measures, we attempted in this research to introduce, develop, and apply the people’s traditions, customs, and clothing, arts, and handicrafts and to introduce the way of life and interactions of the civil society in order to provide the requirements of tourism in Junqan. Moreover, with today’s development of technology and the information society, the need to employ talented native specialists having graduated in urban management is felt more than ever before. The development of public spaces to increase interactions and establish exhibitions is another infrastructure needed in the city of Junqan, which is in line with the development of creative tourism. Each of the above factors can be important and helpful both in the management and in the economy of the city, so they can be considered in line with the role of the brand in the development of creativity in tourism in Junqan.

Introduction
Due to the inattention of designers and architectures to the quality of biological collections during the rapid growth of urbanization, the residents of these collections have faced many problems, the most important being the sharp decline in their quality of life. On the other hand, since home is the most important space in human life, and people spend most of their lives in residential environments, the quality of housing and its role in improvement of the quality of life is a significant issue. Therefore, the present study aimed to investigate how the environmental quality of housing is related to the residents’ quality of life to analyze the mechanism of this relationship. Accordingly, the environmental quality of housing was considered as an independent variable and the quality of life as a dependent variable. In addition, given that the quality of housing is an objective issue, and the quality of life is a subjective issue, a mediating variable was needed with both objective and subjective aspects for analysis of the relationship between the two concepts. Therefore, the notion of health was considered as the mediating variable in this study, and an attempt was made to explain the relationship between the main variables through examination of the relationship between health and the dimensions of environmental quality, on the one hand, and its relationship with the quality of life, on the other.
Theoretical Framework
Based on the objectives and hypotheses of the research, architectural quality was considered as an independent variable, quality of life as a dependent variable, and health dimensions as a mediating variable. According to the research literature, the quality of architecture was evaluated in the form of three indicators: environmental quality, structural quality, and functional quality. The quality of life was evaluated in the form of a psychological-semantic concept including satisfaction with residents’ various aspects of individual and social life. Finally, the dimensions of health were analyzed in the form of three aspects: physical, mental, and social health.
Methodology
After a review of the literature and extraction of the indicators concerning each of the research variables, the theoretical framework of the research was presented. These indicators were examined as a case study using tools including observation, interview, and researcher-made questionnaires at three residential complexes in the city of Shiraz, Iran. A standard questionnaire was used to assess the quality of life. The quality of architecture was assessed using the above tools based on the indicators provided for that purpose. Finally, the residents’ health conditions were assessed using a researcher-made closed questionnaire. To specify the validity and reliability of the questionnaires, the items concerning each variable were first designed and provided to the experts. After a number of the items were corrected and deleted, the final questionnaire was designed in the form of a set of 26 items, and the Cronbach’s alpha coefficient for each group was obtained.
Results and Discussion
The eventual research results follow.
- The physical health of the people in the residential complexes was directly related to the environmental quality of the complexes.
- The mental health of the residents of the residential complexes was directly related to the structural quality of the complexes.
- The social health of the residents of the residential complexes was directly related to the functional quality of the complexes.
- Provision of health dimensions in the residential complexes was directly related to the residents’ quality of life.
Conclusion
1- The quality of architecture in residential spaces is directly related to improvement of the residents’ health conditions. In this regard, the following are significant:
-Improvement of the level of environmental quality promotes all aspects of health in housing, especially the residents’ physical health. This means that the most important factors ensuring the residents’ physical health include the provision of health, creation of environmental comfort in housing, and assurance of the residents’ safety, which lie in the field of environmental quality.
- Improvement of the level of structural quality in housing promotes mental health. Psychological peace is provided in the house through attention to the structural features of housing with respect to the method of spatial configuration, proper spatial zoning, provision of the residents with psychological security, creation of an appropriate visual space in the home environment, and the like. As a result, the residents’ mental health is improved at home.
- Improvement of the level of functional quality improves the residents’ social health in residential environments. We can refer to the capabilities of housing in provision of individual and social functions in the housing environment. are These capabilities include the establishment of collective spaces in the residential environment, creation of a space with functional diversity to perform a variety of activities in public spaces, generation of a spatial hierarchy, and individual and social privacy in space. Such solutions raise the possibility of increasing the interaction between neighbors, which leads to greater recognition among them, formation of the residents’ collective identity, and increase in the desire for social participation among them, which can ultimately contribute to social health.
2- The residents’ quality of health in residential complexes is directly related to the improvement of their quality of life.
This means that provision of all the three dimensions of health in residential environments increases the residents’ quality of life from all aspects. Therefore, if any of the dimensions of health is not provided in a residential environment, it can reduce the residents’ quality of life.
3- The quality of architecture in a residential space is directly related to the residents’ quality of life.
This issue, which is one of the main purposes of the present study, is quite obvious and understandable in light of the above. Thus, on the one hand, there is a two-way relationship between the quality of architecture and health dimensions; on the other hand, the residents’ quality of health in a residential complex is directly related to their quality of life there. Therefore, it can be stated that there is a direct relationship between the quality of architecture in a residential complex and the residents’ quality of life. Hence, improvement of the quality of architecture in a residential space increases different dimensions of the residents’ health, leading to an improvement in their quality of life.

Highlightsurban microclimate is one of the factors for public open spaces design in order to achieve environmental comfort.Feelings of satisfaction will occur when a person has reached a relative level of physical and mental environmental comfort.environmental and form factors such as shape of buildings, location, functional, microclimate comfort can be achieved through environmental comfort. Introduction City and climate are two man-made and natural systems that have direct impacts on each other. Insofar as it concerns human comfort, climate is the result of factors such as sunlight, temperature and humidity, wind, and rainfall. The climate of any geographic location has particular suitable conditions, which have limitations in the field of urban planning and design at the same time.The quality of designing public open spaces as resorts for leisure has an important role in the satisfaction of individuals. A basic characteristic of a sustainable urban environment is its compatibility and harmony with the local climatic features. Therefore, it is a basic prerequisite for planning and designing urban spaces to recognize, understand, and control the climatic effects of urban areas, to which special attention needs to be made by urban planners and designers before implementing urban plans and projects. Man’s feeling of comfort in the environment undoubtedly affects the quality of his behavior and activity. Therefore, it has a great effect on the health of people’s bodies and souls to pay attention to their comfort zones in the design of different urban spaces. On the other hand, the range of activity and the extent of flexibility in an outdoor area depends to some extent on its microclimatic conditions, especially the conditions of sunlight and wind speed.Theoretical FrameworkMicro-climate pertains to areas that are surrounded by larger areas with specific climatic features. The combination of building design and the outdoor space between buildings in an urban area leads in some cases to micro-production of urban climates. As a result, the micro-climate is shaped by the climatic factors of the city, which vary over time under the influence of urban factors. With its positive effects on the environment, micro-climate can be used as a tool in urban planning and design. Feelings of pleasure and satisfaction will occur when a person reaches a relative level of physical and mental (environmental) comfort, and is free from limitations. Moreover, environmental comfort is a factor affecting satisfaction due to the climatic hierarchy. However, urban micro-climate is a factor needed in the design of urban spaces and public open spaces for achievement of environmental comfort and satisfaction.MethodologyShohada Square in the city of Mashhad, Iran has lost its environmental comfort as a public open space with a particular spatial structure surrounded by commercial and administrative buildings and faced with conflicts with urban micro-climatic issues. For investigation of Shohada Sq. for creation of environmental comfort aided by urban micro-climate, a questionnaire with closed questions (in the Likert scale) was tested on a sample of 112 people. The research methodology was based on the analytical method supplemented by inferential statistics (confirmatory factor analysis test), analysis with the Sketch software, and final rhino analysis (umi plugin) to demonstrate that the micro-climatic factors are in line with the comfort of the square.Results and DiscussionThe results of this study indicate that Shohada Square is a public open space with a great potential in terms of location. Its environmental comfort has been degraded severely for the citizens and even the pilgrims despite the rich historical background of this space, the profound historical dimensions it has given to the metropolis of Mashhad as a historical cultural document of the city, and its direct relationship with the Holy Shrine. This is due to the lack of a proper relationship between its surrounding construction and the urban micro-climates and the neglection of the field space itself with respect to the micro-climates. All this has turned the square into a dead space.Therefore, it should be stated that achievements can be made via environmental comfort on the basis of urban micro-climate and consideration and promotion of indicators such as the comfort level of the square, the effect of shadows on comfort, the leisure time spent at the square, the impact of the anciency of the square on the willingness to spend time there, the effect of land use on the willingness to spend time at the square, the impact of climate and space size on the willingness to spend time there, the lack of urban facilities to address the sunlight problem, and the desirability of the flooring .ConclusionIn addition to the above, one can consider environmental and formal factors such as the location and shapes of the square and surrounding buildings, the existing functional and business spaces such as the commercial and administrative buildings on the periphery of the square, as a popular destination for the citizens, thermal comfort and indoor air quality, and micro-climate comfort, which can be achieved through environmental comfort.AcknowledgmentThis article has been extracted from a Master’s thesis in the field of Urban Design entitled Design of open public spaces with an emphasis on the effect of micro-urban climate on the environmental comfort of users: The case study of Shohada Square in Mashhad.

HighlightsThe greenery (shady trees and vegetation) and seating areas provide a good sense of going out in the city‘Gardens and parks’ are one of the variables of the desirability of the urban night landscapeThe majority of nightlife consumers consider their perceived safety to be more due to ‘activities/people on the streets, etc.’The spatiotemporal flow of evening and night-time activities leads to more revenue and financial turnover for the city and municipality IntroductionNightlife and night-time economic attractions are a proper way to expand a working day and the impetus for national growth and development. The present study sought to answer the basic question of how the city of Rasht, Iran could provide a suitable platform for the spatiotemporal flow of activities in the evening and at night.by adopting an analytical framework of time geography and quantitative analysis of nightlife consumption practices in the city center.Theoretical FrameworkThere have been many studies outside Iran on urban nightlife, most of which refer to a combination of social science studies on alcohol and the night leisure industry (Aresi & Pedersen, 2016; Pedrero-García, 2018; Søgaard, 2017). Studies conducted in Iran on nightlife have addressed the topic differently from the research performed outside Iran; these studies have been focused on geography and tourism planning (Shaykh-Baygloo & Soltani, 2019), urban vitality (Ghazanfarpor et al., 2019), cultural factors (Anizadeh, 2018), urban night leisure planning (Kashfi, 2012), and urban night landscape with an emphasis on lighting (AkhavanSaraf et al., 2014). Against this background of research, the present study sought to complement the previous geographic research by adopting an analytical framework of time geography and a quantitative analysis of nightlife consumption practices at the center of Rasht. The innovative aspect of the present study, adopting an analytical framework of time geography, was the combination of two fields, namely nightlife consumption and perception of safety.The perception of safety, that is, the experience of the subjective feeling of being secure (Tulumello & Falanga, 2015), has been known as a key component of a well-functioning city (Cozens & Tarca, 2016). It is influenced by many factors, including the built environment and activities (Bennetts et al., 2017; Piroozfar et al., 2019; van Nes et al., 2016) as an attribute of safer places (Llewelyn-Davies & Partnership, 2004). The literature (Heshmati & Charehjoo, 2018; Park & Garcia, 2019; Piroozfar et al., 2019; Yaran et al., 2019) suggests that the activity factor alone cannot cause spatial differentiation, concentration and thus a greater sense of safety. The solution is to create a high-quality environment by providing different types of complementary opportunities and activities and thoughtfully designing spaces to minimize inconsistencies so as to host a variety of uses and users. This is doubly important in the discussion of nightlife.Urban spaces attract a large number of people at night. The most easily distinguishable time-space layer is that of life and business in the evening and the early hours of the night (usually during 9-11 PM, but sometimes during 6-11 PM) (Rowe & Bavinton, 2011). After evening business, night-time business (11 PM to 2 AM) begins, and the number and diversity of nightlife users decreases dramatically, resulting in fewer services, especially public transportation. The expected outcomes of the present study were the urban nightlife ideals: to identify nightlife consumption practices and evaluate the spatiotemporal flow of activities in two layers of time-space, i.e., evening-downtown Rasht and night-downtown Rasht, in terms of perceived safety, diversity, and inclusivity.MethodologyA questionnaire was used for the data collection. The participants were asked to provide information on the following:(1) geographic locations of night-time activities in the city; (2) types of nightlife activity, including the movies, cafes/restaurants, parks/green spaces, bazaars/shopping malls (commercial centers, hypermarkets, etc.), walking/running, gymnasiums, etc.; (3) arrival time and duration of the last night out; (4) companionship, involving group size and group composition in terms of gender and ethnicity.In a part of the questionnaire, the respondents were asked to evaluate their feelings of safety/lack of safety at a specific (nightlife activity/entertainment) location and state the reason. In addition, the questionnaire included questions about the respondents’ more general patterns of going out and their demographic and socioeconomic statuses. The respondents were asked how often they went out on average and where they often went for nightlife. They were also asked about their genders, ages, lifestyles (living conditions, place of residence), social classes (academic degree, occupation, and type of work), and ethnicities. The data were analyzed with descriptive and inferential statistical methods (chi-squared test and two-step cluster analysis) using the SPSS 26 software.Results and DiscussionThe cluster analysis indicated significant differences in the types of nightlife consumption in downtown Rasht. Nevertheless, the heterogeneity in the space-time paths of nightlife downtown could be summarized in two distinct patterns: going to the park and shopping. These patterns are diverse in many ways, but could be identified at a part of the city center (Sabzeh Meydan Park). The key predictors included the following in descending order of significance: group ethnicity (1.00), group gender (1.00), group size (1.00), type of nightlife activity/entertainment (0.82), average duration (0.60), living conditions (0.48), ethnicity (0.42), location (0.33), gender (0.27), and academic degree (0.18). In this study, occupation and type of work, place of residence, and age played insignificant roles. The findings demonstrated that the majority of nightlife consumers in downtown Rasht felt safe, and this perceived safety could be accounted for mainly (78.2%) by the factor known as activities/people on the street, etc. In the study area, women had a pivotal role in the social production of space, which could be attributed to their perception of the feeling of safety in the nightlife of downtown Rasht.ConclusionAccording to the above findings, the average time of arrival at the first nightlife activity/entertainment (19:28) and the average time spent downtown (3.21 h), Rasht can be a suitable platform for the spatiotemporal flow of activities only in the evening and the initial hours of the night (during 6-11 PM). To conclude, three practical suggestions are made simultaneously for revision of the current procedure: to diversify the activities performed downtown, to manage the area by improving the quality of urban spaces and supporting longer hours of night-time activities, and to provide frequent late-night public transport.AcknowledgmentThis article has been extracted from a doctoral dissertation entitled The Impact of the Physical Environment Attributes on the Perception of Safety and the Patterns of Space Use in Downtown Rasht Using Evaluative and Behavior-Based Mapping, developed by the fourth author under the supervision of the first author and the advisory of the second and third authors at the University of Tabriz.

Introduction
As an Iranian city, Rasht is made up of diverse people of different ages, sexes, physical abilities, and ethnic backgrounds. Many of the world’s urban planning mechanisms have shifted to adopt diversity-oriented approaches and incorporate diversity and difference into urban planning processes by embracing the diversity of urban residents. However, the urban planning mechanism in Iran and the city of Rasht still treats citizens as the same thanks to modernist thoughts, disregarding the differences in age, sex, ethnicity, religion, and physical ability and, consequently, the differences in the citizens’ needs in the city. Planning theory and practice has recently become more conscious of the need to cater to diverse needs and preferences. Planning for diversity and difference is a social interpretation of planning for cities and an approach that considers the needs of different groups of people. This study aimed to identify the factors affecting the realization of diversity-oriented urban planning in Rasht based on the viewpoints of planning experts in the city.
Theoretical Framework
Diversity refers to the increasingly wide range of social and demographic backgrounds of people who live and work in the city. The notion of diversity is now used as a label for policies addressing the heterogeneity of local populations. Certain differences give rise to discrimination and disadvantage, while others do not. Gender, race, disability, and age are critical issues at the root of much discrimination in the society. The critical point is that differences between diverse social groups in enjoyment of the opportunities of urban planning measures are continually reproduced by a range of processes and policies, rendering a number of people mainstream and others marginal. Planning for diversity is a social interpretation of planning for cities, and is an approach that considers different groups of people. There are two conceptual frames, or ways of regarding this profoundly social interpretation of planning for cities, that need to be deployed simultaneously. Firstly, planning for diversity is planning for the diverse range of people who live in and use the city. Secondly, planning the institutional settings to encourage equality of access across places is planning to reduce difference.
Methodology
One of the most efficient qualitative research methods, the grounded theory method was used to help achieve the research purpose; since the research problem is multifaceted, complex, and procedural, grounded theory can be an excellent way to provide an understanding of all the adequate conditions and factors. A semi-structured questionnaire was developed for data collection. Then, in-depth interviews were conducted with ten of the planning experts of this city. Sampling was carried out using a nonrandom sampling method called Snowball Purposive Sampling. In this research, a systematic approach known as grounded theory was applied. The systematic approach emphasizes the adoption of data analysis steps, including open coding, axial coding, selective coding, and the development of a logical model or a visual description of the generated theory. After the collection of textual interview data, analysis and coding began along with sampling. Specialized qualitative research software called Max QDA was used for that purpose. The main tasks of this software are to categorize data and connect the categories and to enable more sophisticated data analysis. In grounded theory, the researcher extracts subcategories, main categories, and core categories from the data, and continues the analysis.
Results and Discussion
Finally, the factors effective on the realization of the diversity-oriented urban planning approach were identified, including 17 main categories and 59 subcategories and the relationships between them. These factors include 1) reflection to govern the urban planning mechanism, 2) significant urban planning policies, 3) improvement of the approach applied to develop urban development plans, 4) modification of the contents of urban development plans, 5) public demand, 6) types of urban planning system, 7) national laws protecting the rights of various social groups, 8) law enforcement, 9) citizens’ cultural and social characteristics, 10) financial strength of municipalities, 11) organizational structure of the authority implementing the plans, 12) inter-organizational coordination, 13) education of urban planning students, 14) the knowledge and experience of the producers of urban development plans, 15) city council approvals, 16) needs assessment, 17) improvement of the quality of the urban environment/diversity-oriented urban environment. In the next step, we selected the category of applying and realizing the diversity-oriented approach from the open coding stage, placed it at the center of the process studied as the central phenomenon, and then related the other categories to it. These categories include causal conditions, strategies, contextual conditions, intervening conditions, and consequences. Next, a diagram called the coding pattern was drawn, which illustrates the relationships between causal conditions, strategies, contextual conditions, intervening conditions, and consequences. In the following step, we developed a theory of the relationships between categories in the axial coding pattern. This theory provides an abstract description of the process examined in this study, namely the application and realization of the diversity-oriented urban planning approach.
Conclusion
The results demonstrate that a wide range of intellectual, procedural, instrumental, organizational, legal, financial, educational, and socio-cultural infrastructures effectively realize this approach. Identification and explanation of these factors can guide the future decisions and practices of Iran’s urban planning authorities to help recognize diverse social groups, respond to their different needs in the city, and address discrimination in urban planning practices.

Introduction
Informal settlements are a fundamental challenge in modern urbanization. Various approaches and plans have been adopted to address this challenge, but many of them have not been associated with success for various reasons, including a lack of understanding of the characteristics of these settlements, especially the demographic dimensions. Studies have demonstrated that housing and habitation in informal settlements is far more frequent in Sanandaj than the national average, and covers more than half of the city’s population. The aim of this study was to analyze the demographic characteristics and indices in informal settlements and compare them to those in other settlements in Sanandaj. The achievements are highly significant mainly because they provide an overview of the active demographic structure and processes in formal and informal settlements. Moreover, many theories that indicate the formation of informal settlements highlight the importance of social, economic, and demographic factors in this regard.
Theoretical Framework
The theoretical framework of this research was based on theories that focus on urban growth and diversity in developing countries. Furthermore, these theories address the typology of urban settlements due to this diversity.
According to the demographic transition framework, rural-urban migration is the initial source of urban growth at the early stages of transition, but natural population growth itself is the fundamental source of urban growth as the transition and urbanization processes continue, and the urban sector grows increasingly larger (Keyfitz, 1980: 149). In the middle and end of the demographic transition, where the rates of death and birth are both low and more or less equal in urban and rural areas, rural-urban migration turns into another factor affecting the growth of urban population.
Undergoing a state of demographic transition and post-transition, the city of Sanandaj, Iran has witnessed both natural growth and rural migration, and has therefore experienced high rates of urbanization. This increasing urbanization has led to the formation of various structures and patterns of urban settlement, including informal dimensions, and represents different trends, types, and patterns in demographic terms.
Methodology
The present research is a quantitative descriptive study with an exploratory nature although it analyzed the current conditions. It was conducted to compare population characteristics and indices in formal and informal settlements in Sanandaj with a secondary analysis of raw data from the population and housing censuses in 2006, 2011, and 2016 in Sanandaj. After the data were processed and prepared, the districts were classified into settlement types based on previous research, and the population characteristics and indices in urban settlements were then compared and analyzed.
Results and Discussion
According to the results, the most dramatic demographic changes in Sanandaj, including those in size, population growth rate, and migration, had occurred in informal settlements. In addition, they are considered as the poles of attraction of the population along with the new settlement areas. There is instability and imbalance among the settlements in terms of the static characteristics of the population, including household density, residential unit quality, academic conditions, dependency burden, and employment status This indicates that informal settlements with larger households, smaller residential units, larger populations per room, and higher ratios of flimsy housing units are excluded from the proper cycle of economic and social urban life. These problems can all lead to occurrence of further urban challenges.
Conclusion
The present study revealed the existence of heterogeneous characteristics and demographic indices in the settlements of Sanandaj. Although the same pattern in terms of population processes cannot be considered for different districts, some settlements are characterized by both higher population growth and poorer housing, occupation, employment, and education. This makes them not only more vulnerable but also potential causes of urban issues and the Achilles’ heel of urban management.
The policy solution proposed in this article is that it is necessary and fundamental to pay attention to the demographic characteristics and indices of informal settlements in the provision and advancement of a comprehensive approach to planning and management in order to upgrade and regenerate these settlements. The results of this paper provide important lessons for planners and policy-makers on population redistribution policies and urban management, and indicate the different dimensions and characteristics of population in districts and settlements of Sanandaj.

Highlights
The residence of informal settlements in the northern part of Tabriz is affected by the legitimate structures and signification of the region.
In their social life, marginalized residents do not pay much attention to the rules set by the upstream planners.
Marginalized residents reproduce the structures of domination in line with their legitimate and implicit structures so that their residence is in line with local values and implications.
Introduction
A particular factor effective in the spontaneous settlements in suburban areas is the behavioral patterns in the residents’ lives and relevant daily activities that could affect the shape of housing. Consideration of the life structure and its effect on the formation of the architecture are topics that have been addressed by various thinkers in fields such as culture and environmental psychology. It is essential to attend to the set of values and meanings of human behavior, viewed as local culture, and the realization of traditions. This process provides a criterion in the construction of spontaneous settlements in marginalized areas. This study investigated and identified the physical patterns of spontaneous settlements and their construction strategies with respect to the lifestyles adopted by the inhabitants of the suburban areas in the northern parts of the city of Tabriz, Iran. In these areas, the residents seem to form the features of the residences according to their local culture rather than the regulations and urban plans.
Theoretical Framework
Many policies proposed to improve the conditions of informal settlements have ignored the structure of life, which has led them to neglect residents’ lifestyles and attempt to impose renovation plans with top-down approaches. Despite the abundance of research, there are more fundamental questions about the residents’ hidden layers faced during their lives. Most of the reviews of research on marginal housing have disregarded the residents’ life structure. This study investigates how the physical patterns of spontaneous settlements take shape with respect to the inhabitants’ lifestyle in suburban areas of the northern parts of Tabriz. Some of the most sophisticated studies conducted in the field include the research by Abrams (1964) and Turner (1967), focused on the participation of residents and their autonomy in the process of improvement and empowerment besides critical views of the destruction and displacement of the suburbs. To proceed with these studies, various conferences and meetings were held between 1996 and 1999 to discuss the empowerment of the poor in the suburbs in order to increase the efficiency of urban development. In addition, different dimensions of informal settlement were addressed in the adopted approaches, in which issues such as economic development, culture, social capital, and security were examined (Hashas 2005, Paul 2017, Petter et al. 2007, Tsenkova 2009, Fernandes 2001, Pugh 2000). Along with the expansion of studies on the culture of marginalization and validation of the structures of local communities, field research needed to be conducted, exemplified by Young and Wilmot (1957), Ganz (1962), and Suttles (1974). Focused on the distinction of the culture of marginalization from the urban culture, these studies have demonstrated that marginalized people define a lifestyle framework with self-assessment criteria, and always strive for social cohesion and protection of internal security.
Methodology
The approach adopted in this research is a qualitative one developed by grounded theory. For selection of the sample, the purposeful sampling method was used with the greatest variety, and semi-structured interviews, observations, and planned samplings were utilized for data collection. In the research sample, forty residents of the examined areas participated, and thirty sample houses were studied.
Results and Discussion
The results demonstrate that the organization of spaces and the physical pattern of spontaneous settlements have been more dependent on legitimate and semantic structures than on signification or domination. In this process, the characteristics of residents’ lives and the physical shape system of the environment in regard to these structures have affected the environmental components, such as neighborhood presence, physical flexibility and adaptability, physical scalability, integration of living space and work, outdoor viability, and widespread housing.
Conclusion
The analysis of the findings demonstrates that the sense of dwelling is more dependent in informal settlements on autonomous patterns to maintain significant legitimate structures than on practical ones (pertaining to extrinsic biological aspects), and the residents always try to protect their existential security as social agents. They can validate structures that respond to all kinds of real perception (concerning intrinsic value aspects). These categories are essential items that should be taken into account in the design and improvement of suburban areas to align the body with the residents’ lifestyle. This factor can indirectly lead to a sense of belonging and sustainable settlement in these areas. Therefore, the planners must improve the physical-biological aspect as a priority to promote these areas according to the local value structures, so that the residents can improve their residential structures under legitimate and significant structures in their social lives in a self-organizing process, in which reference is made to consideration of changeable, adaptable, and flexible housing.
