Various approaches have been adopted to urban form and many elements and indicators have been proposed on spatial scales. However, a comprehensive scale-based study of urban form is lacking. This study seeks to identify the elements and indicators of urban form on different spatial scales. The current study is a meta-synthesis based on a systematic review. A search for the keywords in information databases resulted in 12104 studies, which were reduced to 18 after being screened by means of elimination criteria and quality evaluation. Qualitative content analysis was used for the analysis of the results. Thus, 89 codes (indicators) were extracted and classified into 14 concepts (sub-elements) and 5 categories (main-elements) in terms of 3 scales of city and metropolitan area, neighborhoods and urban blocks. Using Shannon entropy method, the significant coefficient of the indicators was determined and the elements of urban form were ranked. Based on findings, the most important sub-elements on the macro-scale are land use mix, density distribution and type of density. In addition, land use mix, street network and type of density have the highest rank on the meso-scale and street design is placed at the first grade on the micro-scale. According to the rank of sub-elements, land use and density are the most important elements of urban form. Manuscript profile

Following the decline of social capital after the spread of urban sprawl, in the last two decades in various fields, including urban design and planning, growing empirical studies have been conducted to examine the relationship between "built environment" and "social capital. These studies have different and sometimes inconsistent and contradictory results, and researchers do not have comprehensive and sufficient information about the results of findings obtained from all researches.The purpose of this research is to classify aspects of the built environment related to social capital at the neighborhood scale and to find their effect size on social capital. In order to investigate the main purpose of the research based on meta-analysis method, keywords related to neighborhood design elements and social capital were searched in ISI Web of Science and Scopus databases in the period of 2000 to 2019.After identifying and screening the articles, based on the inclusion and exclusion criteria, 33 articles were included in the meta-analysis.After extracting the statistical data of each article, social capital data were coded in two behavioral and cognitive dimensions and neighborhood design elements data were coded in building, density, land use, street and public space dimensions. After analyzing the results using CMA (V.2) software and checking the heterogeneity between the studies with the I2 test, the random model was used to extract the average effect size.Therefore, among the neighborhood design elements the street dimension (ES=0.306) and then the land use dimension (ES=0.120) have the highest impact on the behavioral dimension of social capital and the public space dimension (ES=0.2) has the greatest impact on the cognitive dimension of the social capital.
