  In general, categorization of systems in the context of social – economic issues, cities are considered as one the most complicated ones. Now, metropolitan areas have faced rapid growth and their problems have increased in terms of both quantity and quality aspects. Managing highly complicated systems requires a systematic approach, as well as identifying and guiding relevant elements on the basis of rules and analyses of such approach. The aim of urban management is to assure that the elements of the system are managed in a way that provide the daily functions of a city which facilitates and encourages all economic operations and enables the residents to meet their basic needs, such as housing, access to public facilities and services and income generation opportunities. Urban management integration is an issue emerged from local government, types of current performance and political dispersions in urban area, urban power system and its agents. The aim of this article is identifying and categorizing operant and the tools of integrated urban management in Tehran Metropolitan Area. The concept of city, urban management and the relationship between urban management operant and such concepts are determined on the basis of previous literature. In a mixed approach, needed data are gathered by using case study (qualitative) and survey (quantitative) methods. In this line, explorative studies and interviews are used to devise research theoretic basics. In terms of purpose, present study is a descriptive – analytic research. The statistical population of the research includes two groups: Tehran urban management administrative and senior managers, and urban management experts. A relevant questionnaire was used and sampling method was judgment. Judgment sampling is used when a limited group of people have the relevant information. It is the only sampling method which can be used, regarding the holders of such information. In present study, obtained data from collected questionnaires of urban management experts and managers were analyzed by using Kruskal Wallis test and then the most effective institutions and Operant in various aspects of urban management such as policymaking, monitoring, control, planning and urban and administrative rules and regulations were determined.According to the respondents, in terms of existing rules and laws on policymaking in Tehran Metropolitan Area, City Council (17.2%) plays the biggest role, followed by governmental agencies (17.2%). In terms of monitoring and control, Municipality (20.3%) plays the most vital role. In the meantime, Municipality has the highest share (18.8% frequency) plays the most vital role in urban planning. According to research findings, one can state that 17.2% of respondents believe that governmental agencies enjoy the highest legal rights to determine urban laws and rules. It shows the centralization of domestic political system and its related power links. Regarding executive affairs, Municipality has the highest frequency (35.9%). Ultimately, findings outline that in the opinions of research participants, Municipality is the most competent agency for integrated management of Tehran Metropolitan Area (35.9% frequency). In the meantime, rules and regulations have the highest and important role, among other available tools for urban management. Manuscript profile

  Geography of election is a field of geography with background in European countries from mid of 1910s. Later this field was expanded in 1960s along with little revolution in USA. Geography of election considers condition before and after election; on the other words, it analyzes actors of election through spatial point of view. One of the fields for study on geography of election is study on spatial-local condition of ballot-boxes before election; it was tried in this study to analyze 15th district of Tehran municipality using GIS for 2 cases: first case is relationship between demographic zones and quantity of ballot-boxes and second case is way of access to hospital and clinic in case when unexpected accident is occurred. 15th district of Tehran is one of the 22-fold districts of Tehran metropolitan, located in southeastern of Tehran at entrance gate of old Khorasan road. According to predictions of a universal plan, population of this district will be 942400 people in 2021. Therefore, 15th district is one of the important demographic centers. In regard to such condition, spatial-local analyze of GIS maps is considered in this research which accordingly, relationship between population and quantity of ballot-boxes in districts is not suitable; actually ballot-bases of district is not distributed proportionally considering current population in its areas. Moreover, positions of local hospital, firefighting stations as well as clinics existing in this district are considered in relation to ballot-bases. Condition of mentioned district’s access networks is interested and findings are shown lack of a planned systematic network. Manuscript profile

  The increase of urban population and its post-effects is one of the currentproblems and difficulties of the people at the world, regional, or national scales. Therise of metropolitan of Tehran in our country has changed the urban order. Its spatialexpansion not only has created new alleys, city divisions, and new towns, but alsochanged the small and old population centers of suburban villages into theconcentrated population poles. As a result, the unique spatial order established before1335 in Tehran and its suburb, were altered due to some economic, social, and politicalactivities and all the city and its periphery were developed to an enlarged spatialorganization. This process of changes created a new form of spatial organization whichis now called "urban region", "urban complex", or "urban system". Manuscript profile

  Background and Objective: Urban expansion causes fundamental changes in the ecological landscape structure and function and a gradual change in the spatial structure and pattern of the landscape. Due to the importance of understanding the components of urban environment and how to understand the interactions between these components, the aim of this study is the urban-rural gradient analysis of Tehran using landscape metrics to quantify the landscape pattern.Method: Research data were collected in 2019 and the combination of gradient analysis and landscape metrics has been used to quantify the pattern of Tehran landscape. Land use maps of Tehran were classified using Landsat 7 and 8 satellite images related to 2008 and 2018 in ENVI 5.3 in categories of built-in land, open land, vegetation land and water. For the gradients analysis, a number of 4km×4km transects were designed in the four main directions, and passing through region 12 of Tehran. To calculate the mestrics of Number of Patches, Patch Density, Edge Density, Percentage of Landscape, Mean Patch Size and Mean Shape Index on both landscape and class levels used the moving-window technique.Findings: From 2008 to 2018, urban development has increased the Patch Density in the landscape. So in the central transect the continuity of the landscape has decreased and the fragmentation of the structural components has increased. At the level of the landscape, the Number of Patches and the Edge Density have increased dramatically. However, the Mean Patch Size and the Mean Shape Index have decreased. At the class level, the Mean Patch Size of open lands and built-in land has increased.Discussion and Conclusion: Along transects in addition to land use changes, Shape and Patch Density have also changed, and the process of these changes along transects is different. The percentage of built-in lands is the dominant matrix in transects near the commercial center of Tehran, and the area of vegetation lands and water has decreased from 2008 to 2018.  Manuscript profile

  Homelessness is a pattern of habitance which does not follow the essential standards of housing. This type of habitance forms based on numerous factors; such as personal and structural factors. The aim of this research is identification of structural factors effective on homelessness formation in Tehran metropolitan area. The methodology of this research is practical, based upon the aim and descriptive-analytical, based upon the method and nature. Considering the aims of the research, at first, the factors affecting homelessness formation were extracted out of previous studies and with emphasize on right to city approach (which is the main approach of this research) and categorized into three political, economic, and social groups and into 15 criteria. These factors were written as a questionnaire and were asked from 20 experts (university faculties) to fill it. Through Fuzzy SWARA, which is one of the new methods of MCDM, and then Fuzzy ARAS, each of these factors and criteria were weighted and prioritized, respectively. The results obtained from the Fuzzy ARAS method showed that political and economic factors are the most important factors in homelessness formation by 0.4089 and 0.3909 weights, respectively. Among 15 criteria, the land and housing allocation policies (political factor), commodity land and housing under allocation approach (economic factor) and new urban policies (political factor) and demographic composition (social factor) were the most important criteria effective on homelessness formation in Tehran metropolitan area Manuscript profile

  The worn out texture of Tehran city is 3268 hectares, which accounts for about 5 percent of the total area of the city of Tehran, and the district 12, which is the historical core, is one of the worst urban areas in Tehran. The emergence of various social anomalies in Tehran's metropolis has become a major concern for urban managers. Therefore, this research was conducted with the aim of investigating the spatial patterns and facilitating conditions of committing crimes in the area of worn out texture of the region of 12 metropolitan area of Tehran. The current research is applied and its method is analytical, comparative. In this study, tests for the nearest neighbor and kernel density estimates were used to identify spatial patterns of crime distribution. The statistical population of the present study consisted of convicted offenders who have been filed in Tehran's clinics. As a statistical sample, 560 cases of crimes in district 12 of Tehran municipality have been investigated. The findings show that the concentration center of mass corpses has been formed in central, northeastern and northwestern parts of the district 12 of Tehran, which indicates the unfavorable situation of this section in terms of delinquency than other parts of it. has it. The highest percentages of crimes occurred in blocks of 40-60, 60-80, 80-100% unbearable. From the total of 560 crimes committed, 509 cases equaled 87.69% of all crimes occurred in unrelenting blocks with a high percentage of infamy. Manuscript profile
