 Following the growing urbanization, choosing and providing housing has become one of the mos t important issues for planners as well as people. Developing a comprehensive program of housing needs complete identification and deep analysis of widespread dimensions of housing and factors affecting them. In the meantime, addressing housing indices, as the key planning tool forming its main thrus t, can be the mos t critical step of planning. By conducting research on identifying and analyzing different housing indicators, the effectiveness of housing programs can be greatly increased. However, among the policies and plans that have been made due to the overcoming of economic factors and the lack of clarification of the good housing index, the qualitative indicators of housing have remained somewhat diminished relative to its quantitative dimension, and planners have more focused on providing housing. This research seeks to find and compare the angles of unders tanding and evaluating the residents' viewpoints on the desired housing, and ultimately, address the impact of location on the mental valuation of residents about the cons tructive components of housing quality. The research method is descriptive-analytical and in order to achieve the desired goals, the qualitative indicators of desirable housing are surveyed from residents' point of view in Shahrak-e-Gharb and Monirieh neighborhoods of Tehran. In the formulation of the questionnaire, 48 items are developed in two areas of the residential unit and residential environment, of which only 13 indicators have a significant difference between the two neighborhoods indicating that the spatial domain has no effect on residents’ valuation of housing quality indices and also the average values given to the items show the great importance of the quality of housing for citizens. 

Social diversity in the neighborhood districts has been the new approach for the challenges resulting from varieties in cities. Social interpreters of this policy are to create neighborhoods where people of different ages, ethnic-racial backgrounds, income, etc. take a place in it. In this regard, many designers by using the concept of different forms of ownership such as housing schemas, different types of constructing and housing etc. have tried to promote it. Due to the less interest that came toward this issue, the knowledge of this mechanism is poor in urban ecology of Iran. The aim of this study is to assess the effects of urban design in promoting the social mixing which is determined with the research of the Abadan community areas. Relevant parameters have been studied with library studies, field visits and by the use of qualitative and quantitative analytical methods. Therefore, after reviewing the relevant concepts, we are going to test hypotheses by the exامینation of case studies, and finally, the influences of urban design criteria are presented.

The expansion and growth of cities is a remarkable phenomenon in urban planning literature, so that unpredictable developments have become more evident in recent decades, especially in cities that have undergone changes in their physical structure following the promotion of their political role. The present paper seeks to identify the factors driving growth in the developed areas of Ardebil city and extract basic factors and variables by investigating development of Ardebil. In this study, 27 variables have been tested in 920 expansion blocks during the years 1996 to 2011 using GIS and factor analysis. Four main groups including congestion factor, external factor, access factor and facilities are identified as driving forces of growth. The final combination of four factors in the Arc GIS environment show that the north, east and south east blocks of Ardebil had a higher score than the other blocks; in other words, these factors have the most effect on the growth of these areas. In addition, the Southwest blocks with the lowest score of between 0 and 2 have had the least impact from among the factors mentioned.

Studies conducted in the field of behaviour show that the necessity of noticing and determining urban space behaviour in field studies as well as surveys on dynamic small spaces is undeniable. Small urban spaces, including people-oriented spaces, involve social interactions. This study aims to consider the effect of small urban spaces on the volume of people’s social interactions and participations. The sample group consists of 184 residents and passers-by in the centre of the Sultan Mir Ahmad neighbourhood on different days of the week and at different times of the day. Information on variables was obtained through the behavioural questionnaire together with the related theoretical analysis. The Pearson correlation coefficient was used to determine the relationship between behavioural indicators and people’s turnout, while the regression model was used to determine the weight of each index. According to the studies, components such as awareness, people, purpose, etc. can be impactful from different perspectives in the incidence of behaviour in urban spaces. It can also identify features of behaviour in urban spaces, which can overall be considered in studies on urban space and behaviourism. The results show that there is a significant relationship between the neighbourhood centres considered in the study; five indicators show the correlation to preferential behaviour ranging from 39% (highest) to 19% (lowest).

Today, with the development of urbanization and increased abnormal behaviors, particularly urban crimes, prevention of social harms is of great importance. Social Sciences and Urban Development can prevent crime in urban areas by understanding cultural and social traits alongside other actions, in a way that the wrongdoer finds less opportunity for acting a criminal behavior in urban areas. The theory of social capital is intrinsically simple and affecting many other components. The core idea of social capital can be found and summed up in the word "relationship". Members of the community can cooperate and work together through making contacts with each other sustaining this relation. And thus they learn things that cannot be easily achieved alone or is hard-won. Humans are linked through a series of interconnected networks and tend to have values in common with other members of the network. And by expanding networks constitute an asset that can be considered as a form of capital. Obviously, the more people get to know each other and the more common outlook is found within them, we'll have a richer social capital. On this basis, this research will examine social capital in two dimensions, cultural (types of the trust) and structural (social participation and emotional and material support of network). And tries to study the relationship between social capital and social problems in the Pardis new city after explaining the concept of social capital; This research was conducted with survey method using a questionnaire technique. The statistical populations of the study are residents of Pardis new town, who have been selected though a random cluster sampling method. The sample size was determined as 400 people using Cochran Formula and finally data analysis was done with SPSS Software. The results show that increasing social capital components (cooperation, solidarity and social relations), social problems in new towns is reduced.
