In recent years, the use of grounded theory methodology has increased in scientific fields related to the built environment, especially in urban planning and design. On the other hand, researchers' lack of attention to the foundations and methodological considerations of grounded theory and its readings has sometimes led to a type of methodology with eclectic readings, which sometimes lacks and conflicts the nature of the grounded theory methodology and the primary considerations of the intended reading. Despite this, the review and evaluation of the quality of such research in the scientific fields related to the built environment, particularly urban design and planning has been done less. Therefore, the aim of the present study is to systematically evaluate the studies using the grounded theory methodology in urban planning and design in order to understand the appropriate application of the key tenets of this methodology in this field of knowledge and to provide suggestions for future applications. In this regard, the eligible studies have been selected by systematic search of papers published in reliable Persian-language scientific databases applying the systematic review method. After screening the existing studies based on the specified criteria, 44 studies published until 2019 were selected and evaluated based on the evaluation criteria of the grounded theory methodology. The results of the methodological evaluation of the conducted researches based on the grounded theory methodology showed that despite the increasing use of this method in urban planning and design research, many of these research have been unsuccessful in fully and accurately applying the principles and stages of the grounded theory methodology and its readings, and their results have been reduced to a diagram, model and conceptual framework instead of a theory as the expected achievement from the application of this method. In addition, the results of the present study showed that a number of the research only use a set of techniques of the grounded theory methodology including coding or memo writing. Neglecting important processes such as theoretical sampling, constant comparison and in-depth analysis of categories, has caused that these studies did not go beyond the level of description, and while limiting themselves to presenting descriptive themes and narratives, they rarely achieve theory building as the aim of the grounded theory methodology. Based on the findings of this paper, improving the quality of research based on the grounded theory methodology in the field of urban planning and design requires researchers with a correct understanding of the nature, characteristics and principles of the grounded theory and a deep insight of the readings of this method and their differences, in order to measure the appropriateness and justify the choice of the appropriate reading based on the aims and characteristics of the research.

Highlights:Artworks concerning frontages as media of communication among the artwork, the artist, and the public and frameworks for interaction with locationsCommon viewpoint held by untrained observers (citizens), trained observers (visual art specialists), and creators (artists) in the appraisal of the perceptual-visual desirability of muralsCloseness of the citizens’ and artists’ attitudes toward the appraisal of the perceptual-visual desirability of muralsCitizens’ greater appreciation of the use of creative designs with rhythms and formal contrasts in the appraisal of the perceptual-visual desirability of murals IntroductionAs subway stations are regarded as public spaces in cities, their frontages, involving public artworks, especially murals, are taken into account as part of the urban townscape. The artworks on frontages can provide a medium for interaction, functioning as a visual communication system among the artwork, the artist, and the public. Therefore, it is important to identifying the factors influencing the visual preferences of the audience. The aim of this paper is to investigate the effect of the visual elements of murals on the perceptual-visual desirability of frontages at the Tehran Theater subway station. It seeks to answer the question of how the visual elements of the murals at the station affect the perceptual-visual desirability of the station frontage.Theoretical FrameworkAmong the large number of visual components assumed by various theorists, the main common components taken into account is this research include color, shape, texture, line, tonality, and light (Jansen, 1998: 69). This study investigates element quality, the quality of the relationship between elements, and that for figures and the ground (Pakzad, 2006) to achieve the degree of visual desirability in response to questions about the aesthetic component and the scape quality. The element quality is mural, and the relationship between the murals is considered for appraisal of the quality of the relationship between the elements. Moreover, the relationship between the mural and the wall is considered for appraisal of the quality of the relationship between the figure and the ground. The components related to the quality of the element include intensity, tension, and ingravibility, those pertaining to the quality of the relationship between the elements include balance, symmetry, proportion, dominance, clarity, and density. The components concerning the quality of the relationship between a particular element and others (figure and ground) include contrast, opposition, conformity, advantage, hindrance, emphasis, enclosure, narrowness, openness, sequence, and concentration (ibid.: 121-136)MethodologyFor achievement of the research aim, a mixed method was adopted based on data collection through archives, observations, interviews, and visual preference techniques. Among different cities, Tehran was selected due to its position, and the Tehran Theater subway station was chosen among different stations because of its location in the proximity of Vali-asr Street, Tehran Theater, and Daneshju Park. Then, nine murals were selected from among those available at the station. Given the nature of the data, the methods of regression analysis and correlation analysis were used along with SPSS techniques for analysis of the collected data.Result and DiscussionThe results indicated that perceptual-visual desirability existed in all the three groups: untrained observers (citizens), trained supervisors (visual art experts) and creators of artworks (artists). The findings also demonstrated that tonality (degree of darkness/brightness), shape (design), color, line, and texture exhibited the greatest impacts on perceptual-visual desirability, in that order. The elements of shape, color, tonality, line, and texture played the greatest roles, in order of priority, in the perceptual-visual utility of the station frontage for the citizens, the elements of tonality, shape, line, texture, and color for the specialists, and shape and tonality, color, and line and texture for the artists. The most important reasons for these differences follow. The main reason why tonality was selected as the first priority by the three information sources is the community’s need to observe color diversity at different levels of the society. Unfortunately, this field has been neglected for years. However, its negative effects, such as the increase in the number of patients with depression, are evident. The second priority involved the designs and patterns used in the murals, which demonstrated the significance of form and content and of the choice of subject and consideration of the aspects of visual beauty. In the studied cases, the messages and feelings that the artist tried to convey to the audience had a negative impact on citizens’ perception although understood to a large extent by the audience, as the predicted lighting was not considered properly, the mural lights were used only occasionally, and inappropriate accessions led to visual disturbance. ConclusionThe results indicated perceptual-visual desirability in all the three groups of untrained observers (citizens), trained observers (visual art specialists), and creators (artists). Furthermore, the citizens’ and artists’ opinions were close to each other. The citizens appreciated the use of creative designs with rhythms and formal contrasts, being satisfied both with the location of the murals in terms of visibility and view-shed and with their association with the frontages, but not with the lighting of the works. These were identified as the main perceptual-visual desirability factors in the studied samples.

Highlights Simon Bell Landscape Analysis Technique is an appropriate technique in townscape analysis with a physical approach. Spatial, structural and ordering organizing patterns have the most scores from the experts' viewpoints in the Imam Khomeini Square, respectively. Patterns of visual organizing have the highest scores on the eastern, northern, western and southern sides of the studied square, respectively. Introduction Townscape is a complex environmental phenomenon in physical and perceptual terms, created by various layers of form, function, and meaning through interaction with the human mind, and plays an important role in promotion of the visual and perceptual capabilities of urban spaces. Although mere view and reading of the city as townscape will not be responsive to the complex urban problems, it is necessary to consider townscape as a basic, essential tool (although not sufficient) for reading the city text in order to respond to part of the urban issues and the rights of citizenship. The aim of this paper is to evaluate the visual and spatial quality of Imam Khomeini Square in the city of Qom, Iran based on expert viewpoints in order to answer the main research question: Based on the criteria and sub-criteria derived from Simon Bell Landscape Analysis Technique, which side of Qom’s Imam Khomeini Square is prioritized for redesign intervention? Theoretical Framework In visual analysis, different approaches to the subject can be adopted, some of the most important being the place-based approach, visual approach, subjective approach, physical approach, organizational approach, and visibility approach. Among the above, the physical approach is selected as basis for this paper, in turn based on the Simon Bell landscape analysis framework. In his book Elements of Visual Design in the Landscape, Bill proposes this framework to designers as an alphabet of aesthetics. This framework includes basic elements, variables, and patterns of visual organization, as follows. Basic elements: Point, line, plane, solid volume, open volume. Variables: Number, position, direction, orientation, size, shape (form), interval, texture, density, color, time, light, visual force, visual inertia. Patterns: The organizational principles can be grouped into three categories, as follows. Spatial: nearness, enclosure, interlock, continuity, similarity, figure and ground. Structural: balance, tension, rhythm, proportion, scale. Ordering: axis, symmetry, hierarchy, datum, transformation (Bell, 2007: 22). In visual analysis, different approaches to the subject can be adopted. Some of the most important approaches include the place approach, visual approach, subjective approach, physical approach, organizational approach, and visibility approach. Among the visual analysis approaches, the physical approach is selected as the theoretical framework of this paper, in turn based on the Simon Bell landscape analysis framework. In his book Elements of Visual Design in the Landscape, Bell proposes this framework to designers as an alphabet of aesthetics. The presentation of this alphabet follows a tripartite structure. First, the basic constituents of each landscape are investigated and discussed. Each of these basic elements may be varied in a number of ways. They may also be organized into different patterns. It is the combination of these three components—the element, its variation, and its organization—that describes the existing landscape patterns, or produces new visual designs and patterns. An appropriate design contributes to accurate choice of elements and variables and of coherently harmonious modes of organization. The components of the tripartite structure are as follows (Bell, 2007: 22). Basic elements: Point, line, plane, solid volume, open volume. Variables: Number, position, direction, orientation, size, shape (form), interval, texture, density, color, time, light, visual force, visual inertia. Patterns: The organizational principles can be grouped into three categories, as follows. Spatial: nearness, enclosure, interlock, continuity, similarity, figure and ground. Structural: balance, tension, rhythm, proportion, scale. Ordering: axis, symmetry, hierarchy, datum, transformation (Bell, 2007: 22). Methodology To help achieve the aimof this research, a descriptive-analytical method with a qualitative-quantitative approachwas applied. For assessment of the current conditions, the required data were collected and analyzed based on the Simon Bell Landscape Analysis Technique using observation, photography, and the SWOT and AHP techniques. After the research literature was reviewed, an initial survey and analysis was made of the visual qualities supported by the framework through field observation and photography of the square. Then, the strengths, opportunities, weaknesses, and threats of the tripartite organizing patterns of all the square sides were examined in SWOT tables. Next, the criteria and sub-criteria of the selected framework were weighted. For that purpose, the average viewpoints of thirty urban experts were taken into consideration using a questionnaire, evaluation matrices, and the AHP technique. The rate of inconsistency in the experts’ judgments was less than 0.1, indicating the consistency and logical validity of the experts’ viewpoints. Results and Discussion According to the research findings, the townscape analysis of Imam Khomeini Square based on the selected framework rates the spatial organizing pattern 43.9%, the structural organizing pattern 38.3%, and the ordering organizing pattern 17.8%. Overall, the evaluation of townscape organizing patterns exhibited the highest value, i.e. 44.4% of the score, on the eastern side, 29.4% on the northern side, 16.4% on the western side, and 9.8% on the southern side. Conclusion The results of the present study demonstrate that the spatial, structural, and ordering organizing patterns received the highest scores, in that order, from the experts’ viewpoints on the four sides of Imam Khomeini Square. In the spatial organizing pattern, the highest scores concerned the sub-criteria of figure and ground, interlock, enclosure, continuity, similarity, and nearness, in that order. In the structural organizing pattern, balance, proportion, rhythm, scale, and tension scored highest, and hierarchy, axis, symmetry, datum, and transformation obtained the highest scores in the ordering organizing pattern. The patterns of visual organizing exhibited the highest scores on the eastern, northern, western, and southern sides of the square, in that order. Therefore, the southern side of the square was prioritized for redesign.

Nowadays people’s health (physical, mental and social) is one of the main dilemmas of societies living in metropolitan areas. In this regard, urban design, as one of the influential disciplines among many others, seeks to find solutions to help solving these dilemmas by focusing on the physical and functional dimensions of the urban environment. The main questions of this paper are: what are the effective physical-environmental attributes on the social health of citizens and which of them are more effective? Accordingly, the main objective of this paper is to study and compare the effects of physical- environmental attributes on people’s social health. To achieve this aim, multiple regression method was applied to study, analyze and test the assumptions in order to (1) measure correlation among the mentioned indicators and social health and (2) to identify more effective indicators to predict social health. The study results demonstrate a few common indicators in both neighborhoods; some indicators in distinct neighborhoods have mutual correlation with social health. However, some of the indicators have no significant correlation with social health, these include age, job activities, suitable lighting of public spaces and car ownership. Some indicators have the most correlation in both neighborhoods; they have more certain correlation with social public life of people .These indicators include security and low crime rate in neighborhood, inclusiveness of public spaces, cohesion among neighborhood residents, safety and security of children in public spaces, sense of attachment to the neighborhood, education and townscape quality. In particular, security and low crime rates, sense of attachment to the neighborhood and inclusiveness of public spaces have a high correlation with resident’s social health. Results of the third assumption indicated that there were some differences among correlations between independent variables and social health in the two neighborhoods, one with a historical and traditional social and physical construction and another being a completely new grid neighborhood. Investigating the fourth assumption in the last stage, a limited number of indicators was extracted from the indicators with mutual correlation with social health to predict social health and form the regression equation. Regression results for Dardasht neighborhood indicate that only four indicators (among the indicators with a significant correlation with social health) are obtained as significant indicators in the regression results. Only the following indicators have enough significant predictive role for the dependent variable (social health): availability of gathering spaces, inclusiveness of public space, suitable security and low crime rate, social cohesion among neighborhood residents. However, there is not much difference between coefficients. The highest predicted effect is related to inclusiveness with 1.921 unstandardized coefficient B and the least predictive effect is related to social cohesion among community groups with 1.571 unstandardized coefficient B. The significant indicators in the regression equation for Mulla-Sadra neighborhood are more than those for Dardasht neighborhood, i.e. there are enough significant effect to predict the dependent variable. These indicators include security and crime rate, sense of attachment to the neighborhood, education level, inclusiveness of urban spaces, safety and security of children in public spaces, and suitable townscape of public spaces. Security and inclusiveness have the most coefficient value (2.345 and 1.939, respectively) and suitable townscape has the least coefficient value (1/374). The results indicate that only two indicators, security and inclusiveness, are common among regression results for the two neighborhoods, indicating the highest generalizability of these two indicators regarding different social and physical attributes of these two neighborhoods.

By design, some features of physical spaces can affect people’s image of time. Reviewing the literature shows a correlation between physical dimension of space and users’ time image; a number of place variables, affecting the duration estimation of time that also causes some environmental norms affecting the sense of place. Although, in urban design studies psychological and perceptional aspects of time image is neglected and there is no codified framework to study that, the present study aims to investigate the role of environmental elements in building and supporting the image of time. To achieve this aim, based on reviewing the related literature, a theoretical framework defined that includes some main variables: Time-quantitative variables, dynamic-time features, non-temporal variables, and normative variables. To approach a practical structure in study, "Naghsh-e-Jahan Square" as a case was studied using a mixed research method including storytelling for data collection and AHP for quantitative analysis. In one hand, a “semi-structure interview” technique employed that the analysis of interviews indicated a structure of temporal concepts in people's description of their daily life in "Naghsh-e-Jahan Square". On the other hand, quantifying norms and environmental elements (according to non-temporal variables) was conducted. AHP technique was used to compare the quantified environmental norms, with the impact level of environmental elements that concluded from Fuzzy questionnaires. The result indicates that square manifests different qualitative concepts in different times. Each one of these concepts are along with evidences as dynamic-time features and also quantitative & qualitative factors.
