The article examines the impact of the virtual public sphere on how urban spaces are experienced and conceived in our data-driven society. It places particular emphasis on urban scale digital twins, which are virtual replicas of cities that are used to simulate environments and develop scenarios in response to policy problems. The article also investigates the shift from the technical to the socio-technical perspective within the field of smart cities. Despite the aspirations of urban scale digital twins (...) to enhance the participation of citizens in the decision-making processes relayed to urban planning strategies, the fact that they are based on a limited set of variables and processes makes them problematic. The article aims to shed light on the tension between the real and the ideal at stake during this process of abstracting sets of variables and processes in the case of urban scale digital twins.

Urban planning as a discipline has been continuously evolving in the past decades, aiming to become the response to diverse issues through transdisciplinarity, innovation, creativity and justice. As a result of an ever- accelerating pace of life, we constantly witness worldwide transitions and turbulences, from environmental crises to socio-economic struggles, that challenge cities, regions, and the nature of the planning discipline itself. Climate change and both natural and man-made disasters render territories fragile and force humans and species (...) to migrate, while the growing urban population requires solutions for sustainable transformation for life in the city and beyond. In this context of increasing uncertainty, the planning discipline attempts to suggest ways forward, yet often lacks in providing tangible examples of how to bridge theory and practice. Within this framework, the conference focuses on the predominant discontinuities that currently characterise the planning field. Those are articulated into two directions of discussion that are in dialogue with and between each other: the urban-rural divide (Track 1 and Track 2) and the academia-practice divide (Track 3 and Track 4). The conference aims to create space for these dialogues to emerge, and to ultimately bridge these gaps by reflecting on our role as researchers, on our position towards, and in relationship with, society and on the effectiveness of practice. The questions that arise are timely and crucial, contemplating on the complexities inherent in a perpetual endeavour for coexistence between humans, species and the environment (Track 5). How can planning reinvent itself? How can we reconcile a holistic perception of territories? Which theories, strategies and methods should planning adopt so as to contribute to a better future for the human and natural species? Which are the tools and practices that will ensure human well-being and coexistence with the world? (shrink)

Semiotics is an innovative science that has latterly entered the field of contemporary research. This knowledge application has become more or less common in urban planning, although gradually and not directly. Various urban phenomena tend to be hidden based on their characteristics, and only their effects can be studied in the city, so semiotics can be an efficient and accurate mechanism to generate qualitative data from cities. This article consists of three sections; First, with an initial review (...) of the fundamental concepts and definitions of semiotics, the SIGN is defined and then based on the theoretical foundations of Saussure's concepts, semiotics indicators are categorized. Next, the prototypes of semiotics from the point of view of Umberto Eco, which is one of the most famous categorizations done in this regard, will be studied. Subsequently, the following classifications will be considered in this article: - Biological semiotics - Ecological semiotics - Computer Semiotics - Social semiotics - Cultural semiotics - Visual semiotics - Visual semiotics In the last section, for each of the seven types of semiotics explained, first, a definition and second Saussure's concepts of it will be analyzed and finally the interpretation of that class of semiotics in urban planning, or in other words, the application of each type of semiotics in urban planning will be discussed.

Lack of physical activity is one of the main cause of obesity. Currently, scientists proposed that teenagers and women are overweight or obese than men in Bangladesh. Furthermore, non-communicable diseases (NCDs) are becoming more prevalent in Bangladesh. By 2050, the illness burden of non-communicable diseases will have a significant impact on the health budget. To reduce non-communicable diseases, physical activity is one of the options. However, the lack of public facilities for physical activities in each community is a concern. According (...) to the Department of Military Estate Administration, Central Circle, DOHS (Defense Officers' Housing Scheme) has a total of 2966 plots and 396.6327 acres of area (640 acres =1 square mile) including 5 DOSH in Bangladesh. However, each DOHS has all the public facilities including structures streets, parks, walking paths, squares, gyms, cultural and sports grounds, walkways, waterfronts, lakes, mosques, cafeterias, public toilets, sitting areas for elderly or passersby, etc for physical activities specially for women, children, and the disabled people. Gulshan, Baridhara, Banani, and Dhanmondi areas are other good examples from Bangladesh where dwellers specially, women and children have facilities for physical activities. Sangmoo Kim, urban specialist said, “it is not over-ambitious thinking to have public facilities; it is a basic need for each city dweller for a healthy life”. This report aims to explore what are the policy drawbacks of the Government of Bangladesh not providing public facilities to perform physical activities in each area. (shrink)

The concept of Tabula Rasa, as a desire for sweeping renewal and creating a potential site for the construction of utopian dreams, is presupposition of Modern Architecture. Starting from the middle of the 19th century to the first half of the 20th century, Iranian urban and architectural history has been integrated with modernization, and western-influenced modernity. The case of Tehran as the Middle Eastern political capital is the main scene for the manifestation of modernity within it’s urban projects (...) that was associated with several changes to the social, political and spatial structure of the city. In this regard, the strategy of Tabula Rasa as a utopian blank slate upon which a new Iran could be conceived “over again” – was the dominant strategy of modernization during First Pahlavi era (1925–1941). This article explores the very concept of constructing a new image of Tehran through the processes of autocratic modernism and orientalist historicism that also influenced the discourse of national identity during First Pahlavi era.

The article presents the reasons for which the issue of providing housing to low-income citizens has been a real challenge in Addis Ababa during the recent years and will continue to be, given that its population is growing extremely fast. It examines the tensions between the universal aspirations and the local realities in the case of some of Ethiopia’s most ambitious mass pro-poor housing schemes, such as the “Addis Ababa Grand Housing Program” (AAGHP), which was launched in 2004 and was (...) integrated in the “Integrated Housing Development Program” (IHDP) in 2006. The article argues that the quotidian practices of communities and their socio-economic and cultural characteristics are related to the spatial attributes of co-housing practices. Drawing upon the idea that there is a mutual correspondence between social and spatial structures, it places particular emphasis on the analysis of the IHDP and aims to show that to shape strategies that take into account the social and cultural aspects of daily life of the poor citizens of Addis Ababa, it is pivotal to invite them to take part in the decision-making processes regarding their resettlement. Departing from the fact that a large percentage of the housing supply in Addis Ababa consists of informal unplanned housing, the article also compares the commoning practices in kebele houses and condominium units. The former refers to the legal informal housing units owned by the government and rented to their dwellers, whereas the latter concerns the housing blocks built in the framework of the IHDP for the resettlement of the kebele dwellers. The article analyzes these processes of resettlement, shedding light of the fact that kebele houses were located at the inner city, whereas the condominiums are located in the suburbs. Despite the fact that the living conditions in the condominium units are of a much higher quality than those in the kebele houses, their design underestimated or even neglected the role of the commoning practices. The article highlights the advantages of commoning practices in architecture and urban planning, and how the implementation of participation-oriented solutions can respond to the difficulties of providing housing. It argues that understanding the significance of the endeavors that take into account the opinions of dwellers during the phase of decision-making goes hand in hand with considering commoning practices as a source of architecture and urban planning frameworks for low-cost housing in this specific context. The key argument of the article is that urban planning and architecture solutions in Addis Ababa should be based on the principles of the so-called “negotiated planning” approach, which implies a close analysis of the interconnections between planning, infrastructure, and land.

Along with environmental pollutions, urban planning has been connected to public health. The research indicates that the quality of built environments plays an important role in reducing mental disorders and overall health. The structure and shape of the city are considered as one of the factors influencing happiness and health in urban communities and the type of the daily activities of citizens. The aim of this study was to promote physical activity in the main structure of the (...) city via urban design in a way that the main form and morphology of the city can encourage citizens to move around and have physical activity within the city. Functional, physical, cultural- social, and perceptual-visual features are regarded as the most important and effective criteria in increasing physical activities in urban spaces based on literature review. The environmental quality of urban spaces and their role in the physical activities of citizens in urban spaces were assessed by using the questionnaire tool and analytical network process (ANP) of structural equation modeling. Further, the space syntax method was utilized to evaluate the role of the spatial integration of urban spaces on improving physical activities. Based on the results, the consideration of functional diversity, spatial flexibility and integration, security, and the aesthetic and visual quality of urban spaces plays an important role in improving the physical health of citizens in urban spaces. Further, more physical activities, including motivation for walking and consequently, the sense of public health and happiness, were observed in the streets having higher linkage and space syntax indexes with their surrounding texture.

The article examines the impact of the study for Levittown of urban sociologist Herbert Gans on Denise Scott Brown’s thought. It scrutinizes Denise Scott Brown, Robert Venturi, and Steven Izenour’s ‘Remedial Housing for Architects or Learning from Levittown’ conducted in collaboration with their students at Yale University in 1970. Taking as its starting point Scott Brown’s endeavour to redefine functionalism in ‘Architecture as Patterns and Systems: Learning from Planning’, and ‘The Redefinition of Functionalism’, which were included in Architecture (...) as Signs and Systems: For a Mannerist Time (2004), the article sheds light on the fact that the intention to shape a new way of conceiving functionalism was already present in Learning from Las Vegas, where Robert Venturi, Denise Scott Brown and Steven Izenour suggested an understanding of Las Vegas as pattern of activities. Particular emphasis is placed on Scott Brown’s understanding of ‘active socioplastics’, and on the impact of advocacy planning and urban sociology on her approach. At the core of the reflections developed in this article is the concept of ‘urban village’ that Gans uses in US in The Urban Villagers: Group and Class in the Life of Italian-Americans (1972) to shed light on the socio-anthropological aspects of inhabiting urban fabric.

The experienced quality of urban environments has not traditionally been at the forefront of understanding how cities evolve through time. Within the humanistic tradition, the temporal dimension of cities has been dealt with through tracing urban or architectural histories or interpreting science-fiction scenarios, for example. However, attempts at understanding the relation between currently existing components of cities and planning based on them, towards the future, has not captured the experience of the temporal layers of cities to a (...) satisfying degree. Contemporary urban environments comprise both lasting and fairly stable elements as well as those that change continuously: change is an inevitable part of urban life. Different aspects of city life evolve with a different tempo: urban nature has its cycles, inhabitants their rhythms, and building materials and styles different lifespans, for example. Recognizing them becomes an especially important issue when future imaginaries are projected onto existing urban structures and when decisions about the details of urban futures are made. This paper aims at bringing environmental and urban aesthetics into the discussion about the possible directions of urban futures. The focus is on introducing the notion of aesthetic sustainability as a tool to better understand how urban futures unfold experientially and how aesthetic values of urban environments develop with time. This concept has some background in the field of design theory, more specifically in sustainable usage and product design, but it has not so far been used in order to study large scale living environments. The concept can prove to be a valuable supporting tool in urban sustainability transformations based on how it captures the experiential side of the physical and temporal dimensions of cities.

The first signs of historical settlements in Tirana date back to the year 1614. These settlements and their road system belongs to the Ottoman city structure. Nowadays this historic northeast area of Tirana consists of a conglomeration of buildings that date back to different historical periods. A good part of these dwellings are informal ones, which damage the morphology of the area. This paper is considering a genuine historical basis to create an intervention model in this specific area of Tirana. (...) The total surface of the area which is rigorously analyzed is 2.08 ha. Regulatory plans that will be considered for this analysis are the regulatory plans of 1917, 1921, 1937, 1953, 1980, up to today (the existing situation of the city of Tirana). The whole area will be analyzed including the typical road system; the typical structure of the dwellings, and the typical morphology of the area. All dwellings will be filed, according to historical dating situation and the existing situation. The current local general (PPV) plan provides a radical intervention in this area which seriously damages the historical heritage of the city of Tirana. This article aims and focuses on a territorial development model recovering it and not damaging it, (in contradiction with the current regulatory plan). The new model will be clearly detailed (up-to-level plans). The city of Tirana needs historical heritage and historical identity. How can one damage such treasure which the time took care so much to create and preserve? Such allusions are to be spoken out loudly! (shrink)

The Second World War and its associated political events of a national and global scale brought new circumstances, which was considerably influenced the development processes of Tehran. During World War II, Iran hoped that Washington would keep Britain and the Soviet Union from seizing control of the country’s oil fields. In 1951 and 1952 Truman worked with Iranian Prime Minister, though unsuccessfully, to regain some of those lost oil rights for Iran. By the late 1950s and President Kennedy’s presidency, he (...) used aid as leverage for social reform. During the early years of 1960s, the Kennedy Administration was urging its allies in the third world to carry out necessary reforms in order to prevent popular discontent and enhance the dominant ideology of ‘modernism’. In 1968, a major piece of legislation, the Urban Development and Renewal Act, enabled the municipality to implement Tehran’s Comprehensive Plan (TCP 1968), which integrated all the elements of a 1960s’ American city such as the separation of functions, highways, suburbs, shopping centers and housing area. The export of these American cities principles can only be understood from the background of the Cold War period, in which the east and west were both competing for cultural colonization of Middle Eastern strategically important cities like Tehran. During this period, the new developments supported by the oil boom of 1970s, were built in different forms to constitute an expanding metropolis. In 1974, the second “International Congress of Architecture” with the theme of “Toward a Quality of Life” held at Persepolis and brought together all leading world architects and planners to review Iran’s progress in its professional response to the challenges posed by increasing oil revenues. This research aims to represent the export of planning as a political means of cultural colonization of the Third World during the cold war period. (shrink)

Citizens can be meaningfully involved in multiple phases of the urban planning process from decision-making to implementation via a dedicated online platform through which they can interact with planners and decision-makers. In historical contexts, local people are essential resources for decision-makers seeking critical local information needed for effective planning and intervention—including what those citizens recall from the past about the area’s social values and the built environment and what they imagine and hope for their neighborhood’s future. This (...) public knowledge, collected through storytelling and mapping, can play a fundamental role in shaping the framework for neighborhood rehabilitation plans. As a foundation for designing an online visual questionnaire to collect local knowledge and understand the views and expectations of local people, this study focuses on theoretical ideas to define a framework for an online visual questionnaire tool. The tool presented provides a common visual language that people can easily understand and use whatever their social class, education, or background. It also has the benefit of enabling citizens and planners to interact directly regardless of their geographical location. To proposing a framework for the online visual questionnaire, the first step was to review some existing visual tools and methods, including analog used for community engagement and digital used in urban planning to encourage and support public participation. Through an analysis of these methods, some important variables and criteria were identified that further our understanding of citizens’ perceptions of their neighborhoods. The next step, as part of a larger study, will be examining a historical public space, including a bazaar, hammam, and cistern—located in the historical context of Yazd— a central city in Iran registered as a cultural heritage site by UNESCO— as a case study with the larger goal of identifying some specific.

Today’s exponential advancement of information and communication technologies is reconfiguring participatory urban development practices. The use of digital technology implies new forms of decentralised governance, collaborative knowledge production, and social activism. The digital transformation has the potential to overcome shortcomings in citizen participation, make participatory processes more deliberative, and enable collaborative approaches for making cities. While digital tools such as digital mapping, e‐participation platforms, location‐based games, and social media offer new opportunities for the various actors and may act as (...) a catalyst for renegotiating urban space and collective goods, digitalisation can also perpetuate or even attenuate existing inequalities and exclusion. This editorial introduces the thematic issue “Citizen Participation, Digital Agency, and Urban Development” which focuses on the trajectories and (dis)continuities of citizen participation through digitalisation and elaborates this with examples from Europe and Asia on how the digital transformation impacts, challenges, or reproduces hegemonic power relations in urban development.

Urban residents have the potential to play a key role in helping to facilitate ecological resilience of wilderness areas and ecosystems beyond the city by helping ensure the migration of nonhuman climate refugee populations. Three ethical frameworks related to this issue could determine whether we have an ethical duty to help nonhuman climate refugee populations: ethical individualism, ethical holism, and species ethics. Using each of these frameworks could support the stronger view that policy makers and members of the public (...) have a moral duty to mitigate the impacts of climate induced migration, or the weaker claim that these impacts should be taken into account when making land-use and planning decisions in urban contexts.

The problem of "lost space," or the inadequate use of space, afflicts most urban centers today. The automobile, the effects of the Modern Movement in architectural design, urban-renewal and zoning policies, the dominance of private over public interests, as well as changes in land use in the inner city have resulted in the loss of values and meanings that were traditionally associated with urban open space. This text offers a comprehensive and systematic examination of the crisis of (...) the contemporary city and the means by which this crisis can be addressed. Finding Lost Space traces leading urban spatial design theories that have emerged over the past eighty years: the principles of Sitte and Howard; the impact of and reactions to the Functionalist movement; and designs developed by Team 10, Robert Venturi, the Krier brothers, and Fumihiko Maki, to name a few. In addition to discussions of historic precedents, contemporary approaches to urban spatial design are explored. Detailed case studies of Boston, Massachusetts; Washington, D.C.; Goteborg, Sweden; and the Byker area of Newcastle, England demonstrate the need for an integrated design approach--one that considers figure-ground, linkage, and place theories of urban spatial design. These theories and their individual strengths and weaknesses are defined and applied in the case studies, demonstrating how well they operate in different contexts. This text will prove invaluable for students and professionals in the fields of architecture, landscape architecture, and city planning. Finding Lost Space is going to be a primary text for the urban designers of the next generation. It is the first book in the field to absorb the lessons of the postmodern reaction, including the work of the Krier brothers and many others, and to integrate these into a coherent theory and set of design guidelines. Without polemics, Roger Trancik addresses the biggest issue in architecture and urbanism today: how can we regain in our shattered cities a public realm that is made of firmly shaped, coherently linked, humanly meaningful urban spaces?

Integration sustainability outcomes give attention to construction ecology in the design review of urban environments to comply with Earth’s System that is composed of integral parts of the (i.e., physical, chemical and biological components). Naturally, exchange patterns of industrial ecology have consistent and periodic cycles to preserve energy flows and materials in Earth’s System. When engineering topology is affecting internal and external processes in system networks, it postulated the valence of the first-level spatial outcome (i.e., project compatibility success). These (...) instrumentalities are dependent on relating the second-level outcome (i.e., participant security satisfaction). The construction ecology-based topology (i.e., as feedback energy system) flows from biotic and abiotic resources in the entire Earth’s ecosystems. These spatial outcomes are providing an innovation, as entails a wide range of interactions to state, regulate and feedback “topology” to flow as “interdisciplinary equilibrium” of ecosystems. The interrelation dynamics of ecosystems are performing a process in a certain location within an appropriate time for characterizing their unique structure in “equilibrium patterns”, such as biosphere and collecting a composite structure of many distributed feedback flows. These interdisciplinary systems regulate their dynamics within complex structures. These dynamic mechanisms of the ecosystem regulate physical and chemical properties to enable a gradual and prolonged incremental pattern to develop a stable structure. The engineering topology of construction ecology for integration sustainability outcomes offers an interesting tool for ecologists and engineers in the simulation paradigm as an initial form of development structure within compatible computer software. This approach argues from ecology, resource savings, static load design, financial other pragmatic reasons, while an artistic/architectural perspective, these are not decisive. The paper described an attempt to unify analytic and analogical spatial modeling in developing urban environments as a relational setting, using optimization software and applied as an example of integrated industrial ecology where the construction process is based on a topology optimization approach.

On 11 March 2020, the World Health Organization declared a pandemic of the COVID-19 coronavirus disease that was first recognized in China in late 2019. Among the primary effects caused by the pandemic, there was the dissemination of health preventive measures such as physical distancing, travel restrictions, self-isolation, quarantines, and facility closures. This includes the global disruption of socio-economic systems including the postponement or cancellation of various public events (e.g., sporting, cultural, or religious), supply shortages and fears of the same, (...) schools and universities closure, evacuation of foreign citizens, a rise of unemployment, changes in the international aid schemes, misinformation, and incidents of discrimination toward people affected by or suspected of having the COVID-19 disease. The pandemic has brought to the fore unpreparedness in critical areas that require attention, amid prospects and challenges. Moreover, considerable reorganization efforts are required with implications for assets, resources, norms, and value systems. COVID-19 is challenging the concept of globalization and stimulating responses at the levels of local and regional socio-economic systems that lead to the mobilization of assets that have been unrecognized earlier on, such as various forms of economic capital, social capital, cultural capital, human capital, and creative capital. For example, through digital channels, local groups are forming to create schemes of support for physical and mental wellbeing. These emerging exchanges lead to various social and technological innovations by building on skills and assets that are less important in the free-market economy, such as empathy, skills for crafts, making and fixing; locally grown microgreens; and micromanufacturing. Isolation and local living are also making it much harder to ignore the civic responsibilities towards communities, meant as individuals, vulnerable groups, and local businesses. Whilst the pandemic is limiting physical participation, this challenging time is uncovering alternative ways of mutual support, which may create long-term benefits for socio-economic systems, including environmental and biodiversity protection, reduction of the air pollution, and climate action. The pandemic’s threat to public health will hopefully be overcome with implications for disruption for an extended period that we are unable to forecast at this stage. It is key to focus on studies recognizing the activities and interventions leading to the recovery of socio-economic systems after the pandemic. Reflecting and planning on how societies and economies will go back to “business as usual” requires new forms of communication and cooperation, imaginative design thinking, new styles of management, as well as new tools and forms of participation in various public policies. Many questions related to the care of the vulnerable, economic restart, and the risk of future pandemics, to mention but a few, are already occupying the academic, scientific, experts, and activist communities, who have started to imagine the “new normal.”.

Context: Philosophical and - more recently - empirical approaches to the study of mind have recognized the research of lived experience as crucial for the understanding of their subject matter. Such research is faced with self-referentiality: every attempt at examining the experience seems to change the experience in question. This so-called “excavation fallacy” has been taken by many to undermine the possibility of first-person inquiry as a form of scientific practice. Problem: What is the epistemic character and value of reflectively (...) acquired phenomenological data? Can the study of experience, despite the excavation fallacy, rely on the act of reflection on lived experience and make sense and use of its results? Method: Through a philosophical discourse, informed by empirical first-person inquiry, we explore the experiential structure of the act of reflection and the formation of the corresponding belief about past experience. Results: We present a provisional first-person model of the experiential dynamics of retrospective reflection, in which the reflective act is characterized as enaction of belief about past experience that co-determines - rather than distorts - its results. From a constructivist perspective on the inevitable interdependence between the act of observing and the observed, the excavation “fallacy” is recognized as an intrinsic characteristic of reflection. Reflection is described as an iterative, self-referential process, guided by a context- and subject-specific horizon of expectations. Implications: Knowing the characteristics of the formation of beliefs about experience is essential for understanding first-person data and for the possibility of their acquisition and use in scientific practice, particularly in the context of second-person approaches to the study of experience. Constructivist content: We relate the proposed understanding of reflection to constructivist epistemology and argue that constructivism provides an epistemological foundation for the empirical study of experience more suitable than the traditional epistemological objectivism of cognitive science. We suggest that the constructive nature of the process of reflection calls for a collaboration between the fields of constructivism, phenomenology, and first-person research, and points towards the potential for their mutual enrichment.

This paper proposes a new classification algorithm for the partitioning of a conceptual space. All the algorithms which have been used until now have mostly been based on the theory of Voronoi diagrams. This paper proposes an approach based on potential theory, with the criteria for measuring similarities between objects in the conceptual space being based on the Newtonian potential function. The notion of a fuzzy prototype, which generalizes the previous definition of a prototype, is introduced. Furthermore, the necessary conditions (...) that a natural concept must meet are discussed. Instead of convexity, as proposed by Gärdenfors, the notion of geodesically convex sets is used. Thus, if a concept corresponds to a set which is geodesically convex, it is a natural concept. This definition applies, for example, if the conceptual space is an Euclidean space. As a by-product of the construction of the algorithm, an extension of the conceptual space to d-dimensional Riemannian manifolds is obtained. (shrink)

This paper deals with Gärdenfors’ theory of conceptual spaces. Let \({\mathcal {S}}\) be a conceptual space consisting of 2-type fuzzy sets equipped with several kinds of metrics. Let a finite set of prototypes \(\tilde{P}_1,\ldots,\tilde{P}_n\in \mathcal {S}\) be given. Our main result is the construction of a classification algorithm. That is, given an element \({\tilde{A}}\in \mathcal {S},\) our algorithm classifies it into the conceptual field determined by one of the given prototypes \(\tilde{P}_i.\) The construction of our algorithm uses some physical analogies (...) and the Newton potential plays a significant role here. Importantly, the resulting conceptual fields are not convex in the Euclidean sense, which we believe is a reasonable departure from the assumptions of Gardenfors’ original definition of the conceptual space. A partitioning algorithm of the space \(\mathcal {S}\) is also considered in the paper. In the application section, we test our classification algorithm on real data and obtain very satisfactory results. Moreover, the example we consider is another argument against requiring convexity of conceptual fields. (shrink)

Do Muslims and Christians worship the same God? We answer: it depends. To begin, we clear away some specious arguments surrounding this issue, to make room for the central question: What determines the reference of a name, and under what conditions do names shift reference? We’ll introduce Gareth Evans’s theory of reference, on which a name refers to the dominant source of information in that name’s “dossier,” and we then develop the theory’s notion of dominance. We conclude that whether Muslims’ (...) use of “Allah” co-refers with Christians’ use of “God” depends on how much weight is given to what type of information in the dossiers of these two names, and we offer a two-part test by which the reader can determine whether Muslim and Christian uses of the divine names co-refer: If Christianity were true and Islam false, might “Allah” still refer to God? And: If Islam were true and Christianity false, might “God” still refer to Allah? We explain the implications of your answers to those questions, and we close with a few reflections about what, in addition to reference, might be required for worship, and whether, from a Christian perspective, salvation turns on this issue.

Since the 1860s, petroleum companies, through their influence on local governments, port authorities, international actors and the general public gradually became more dominant in shaping the urban form of ports and cities. Under their development and pressure, the relationships between industrial and urban areas in port cities hosting oil facilities evolved in time. The borders limiting industrial and housing territories have continuously changed with industrial places moving progressively away from urban areas. Such a changing dynamic influenced the (...) permeability of these borders. Port cities are nodes and logistic points where various flows of commodities, wealth, and knowledge gathered before further re‐distribution. These flows affected port cities by changing their spatial organization and the availabiity of space between borders. The main question here is: How did industrial and urban borders evolve through time in port cities? Through a historical analysis, the article explores the settlements of oil facilities and the influence of oil companies over local, regional, and national governments in creating borders and how it influenced the porosity of port cities. This article, through the petroleum narrative, illustrates the impacts of past borders on the contemporary urban form through the evolution of the French port city of Dunkirk, in the North of France. As a historical study, the article analyzes the changing relationships between petroleum industrial sites and housing areas in the city of Dunkirk, using aerial pictures, archival sources, and regulations of different periods. The importance of this analysis lies in knowing that former oil sites previously located on the periphery of Dunkirk, that were forgotten by the authorities are now located within the current urban tissue. This process demonstrates the importance of historical developments to understand current challenges in the urban planning of industrial port cities. (shrink)

Despite its aesthetic appeal, the Iranian resort Majara is poised to be a sore point among local residents. Looking at the 200 vibrant oddly-shaped domes might make you feel you’re on a Wes Anderson movie set.The Majara Residence overlooking the Persian Gulf offers homes and resort-like accommodation, complete with cafes, restaurants, souvenir shops, tourist information, a prayer room, laundry, storage and more. Located at Hormuz (or Ormuz) Island, a historic port off the southern coast of Iran, the project is designed (...) to attract tourists to the small island and serve as an alternative to high-rise developments traditionally used to house visitors. Presence in Hormuz 2 is a series of urban development projects designed by the Tehran-based ZAV Architects. Majara (which means adventure) is the second phase of this multipurpose cultural residence, aimed at binding together the lives of local people and visitors culturally and economically. On the verge of opening, this project has been heavily criticised by environmental activists and urban experts citing ecological, economic, cultural and social concerns. Such projects have made locals mere servants in service of investors, which impedes the enhancement of their quality of life. (shrink)

The theory and culture of the arts has largely focused on the arts of objects, and neglected the arts of action – the “process arts”. In the process arts, artists create artifacts to engender activity in their audience, for the sake of the audience’s aesthetic appreciation of their own activity. This includes appreciating their own deliberations, choices, reactions, and movements. The process arts include games, urban planning, improvised social dance, cooking, and social food rituals. In the traditional object (...) arts, the central aesthetic properties occur in the artistic artifact itself. It is the painting that is beautiful; the novel that is dramatic. In the process arts, the aesthetic properties occur in the activity of the appreciator. It is the game player’s own decisions that are elegant, the rock climber’s own movement that is graceful, and the tango dancers’ rapport that is beautiful. The artifact’s role is to call forth and shape that activity, guiding it along aesthetic lines. I offer a theory of the process arts. Crucially, we must distinguish between the designed artifact and the prescribed focus of aesthetic appreciation. In the object arts, these are one and the same. The designed artifact is the painting, which is also the prescribed focus of appreciation. In the process arts, they are different. The designed artifact is the game, but the appreciator is prescribed to appreciate their own activity in playing the game. Next, I address the complex question of who the artist really is in a piece of process art — the designer or the active appreciator? Finally, I diagnose the lowly status of the process arts.

Kevin Lynch's books are the classic underpinnings of modern urban planning and design, yet they are only a part of his rich legacy of ideas about human purposes and values in built form. City Sense and City Design brings together Lynch's remaining work, including professional design and planning projects that show how he translated many of his ideas and theories into practice. An invaluable sourcebook of design knowledge, City Sense and City Design completes the record of one (...) of the foremost environmental design theorists of our time and leads to a deeper understanding of his distinctively humanistic philosophy. The editors, both former students of Lynch, provide a cogent summary of his career and of the role he played in shaping and transforming the American urban design profession during the 1950s, the 1960s, and the 1970s. Each of the seven thematic groupings of writings and projects that follow begins with a short introduction explaining their content and their background. The essays in part I focus on the premises of Lynch's work: his novel reading of large-scale built environments and the notion that the design of an urban landscape should be as meaningful and intimate as the natural landscape. In part II, excerpts from Lynch's travel journals reveal his early ideas on how people perceive and interpret their surroundings—ideas that culminated in his seminal work, The Image of the City. This part of the book also presents Lynch's experiments with children and his assessment of environmental-perception research. The examples of both small-scale and large-scale analysis of visual form in part III are followed by three parts on city design. These include Lynch's more theoretical works on complex planning decisions involving both functional (spatial and structural organization) and normative (how the city works in human terms) approaches, articles discussing the principles that guided Lynch's teaching and practice of city design, and descriptions of Lynch's own projects in the Boston area and elsewhere. The book concludes with essays written late in Lynch's career, fantasy pieces describing utopias and offering new design freedoms and scenarios warning of horrifying "cacotopias.". (shrink)

Urban spaces, often emerging outside formal, recognized boundaries, underscore the pivotal role women play in shaping these environments. Despite the enduring influence of patriarchal and hierarchical structures that render these spaces overtly gendered, it is within these contexts that women’s actions become particularly transformative. Drawing from feminist urban theories of the global south, this paper investigates informal placemaking, feminist urban activism, revolutionary placemaking, online protest movements, and the networks that support women’s solidarity groups. Employing a mixed-methods approach (...) that includes case studies, interviews with activists, and social media analysis, this research focuses on Iran, with a specific emphasis on the recent ‘Women, Life, Freedom’ movement. This study not only highlights how women navigate, contest, and reshape urban spaces through feminist urban activism and informal revolutionary placemaking but also anticipates the broader implications of these actions for urban planning and policy. By analyzing and comparing these case studies, we aim to uncover the commonalities, differences, challenges, and opportunities between informal/formal, state-led/bottom-up, and revolutionary feminist placemaking practices in Iran. The findings of this paper are expected to contribute valuable insights into the dynamics of feminist urbanism and suggest avenues for future research in enhancing the inclusivity and responsiveness of urban spaces to gendered needs and activism.

How were the concepts of the observer and user in architecture and urban planning transformed throughout the 20th and 21st centuries? Marianna Charitonidou explores how the mutations of the means of representation in architecture and urban planning relate to the significance of city's inhabitants. She investigates Le Corbusier and Ludwig Mies van der Rohe's fascination with perspective, Team Ten's interest in the humanisation of architecture and urbanism, Constantinos Doxiadis and Adriano Olivetti's role in reshaping the relationship (...) between politics and urban planning during the postwar years, Giancarlo De Carlo's architecture of participation, Aldo Rossi's design methods, Denise Scott Brown's active socioplactics and Bernard Tschumi's conception praxis.

This article connects value-sensitive design to Gibson’s affordance theory: the view that we perceive in terms of the ease or difficulty with which we can negotiate space. Gibson’s ideas offer a nonsubjectivist way of grasping culturally relative values, out of which we develop a concept of political affordances, here understood as openings or closures for social action, often implicit. Political affordances are equally about environments and capacities to act in them. Capacities and hence the severity of affordances vary with age, (...) health, social status and more. This suggests settings are selectively permeable, or what postphenomenologists call multistable. Multistable settings are such that a single physical location shows up differently – as welcoming or hostile – depending on how individuals can act on it. In egregious cases, authoritarian governments redesign politically imbued spaces to psychologically cordon both them and the ideologies they represent. Selective permeability is also orchestrated according to business interests, which is symptomatic of commercial imperatives increasingly dictating what counts as moral and political goods. (shrink)

Serious games with their educational or skill development purposes besides entertainment, have been used in various fields such as architecture, landscape architecture, urban planning, cultural heritage, and learning of language and culture, easing the data absorption process of the specific topic for the user. The use of serious games in the cultural heritage or cultural landscape, as a subtopic, can have a role in its preservation in addition to the information transition ability. Yedikule Bostans is a serious game (...) designed for cultural heritage, its importance, and maintenance ways. The case study of this article is the İstanbul’s market gardens, existing plenty of them in İstanbul, which have remained since ancient times surviving despite the difficulties of urbanization. This research is focusing on the Yedikule Bostanları with their 1500-year history which are associated with the Theodosian Walls, registered in the list of historic areas of İstanbul in UNESCO. The serious game presented in this research with its immersive text-based time-traveling theme about these gardens aims to attract the public's attention to their perishing danger. Thanks to the abilities of the Twine software used in the game's development, we provide a charming journey to the users throughout the game to increase their awareness of the inherited farming culture and more comprehensively the cultural heritage and cultural landscape, meanwhile.

While many papers may claim that virtual environments have much to gain from architectural and urban planning theory, few seem to specify in any verifiable or falsifiable way, how notions of place and interaction are best combined and developed for specific needs. The following is an attempt to summarize a theory of place for virtual environments and explain both the shortcomings and the advantages of this theory.

Smells seem to offer a great opportunity to restructure the reality of the individual. Yet, the olfactory dimension is rarely part of design strategies in architecture, urban planning or landscape urbanism. As designers, we learn to compose mainly with shapes, shapes whose full scale and effects on our senses we will experience only when constructed. However, we should be primarily concerned with creating spaces that not only open the imagination of the individual but also allow positive moods to (...) thrive. In this scheme, all the senses should be called, not just our vision, as is too often the case. The fields of architecture and environmental design must evolve and train professionals capable of conceptualizing both tangible and intangible forms. In this logic, architectural structures offer a way to call upon our own mindscapes; and within the discipline of design a new field of specialization exists: smellscaping. (shrink)

Arakawa and Gins have been fomenting revolution for a long time. In the last twenty years their attention has turned more and more towards architecture and urban planning as a way of reforming our bodily existence. Their proposals enter daily life rather than staying in the isolated sphere of the museum or gallery. These constructions are to be lived in, not contemplated. Will daily life then blunt or sharpen Arakawa and Gins's power to educate and revise our "architectural (...) bodies"? (shrink)

Descartes and Architecture -/- The article analyses the architectural metaphor in Descartes' Discourse on Method and The Seventh replies. The idea of Descartes' project, introduced to the reader as a construction of a building and planning of a city, is much more indebted to its architectural imagery than, or so its critics say, is "sound" for a philosophical theory. Architecture is an analogon of philosophy in Descartes' texts. By producing a figure of philosopher-architect, Descartes tries to legitimate his philosophical (...) theory using architectural discourse. Descartes always uses the examples of architecture and urban planning when he intends to introduce his great project of a new beginning in philosophy. This new beginning is manifest in two levels: first, as a denial of traditional metaphysics of the Schools in the Discourse, and second, as a denial of one’s own beliefs in the Meditations using methodical doubt. In the conclusion, the article emphasises through Derrida's analysis of metaphor that, given the metaphysical nature of any metaphor, Descartes’ metaphor also cannot appear as a mere rhetorical figure.

The book consists of articles in various fields written by graduate students. The articles were selected among many which applied to the "International Student's Work Competition". Then divided into two categories and published a two-volume "The World After the Pandemic" book series. Articles in this volume are related to "Life Sciences and Medicine", "Lifestyle and Urban Planning", "Technology" and "Education" regarding the world after the COVID-19 pandemic.

Among the main components of a smart city, the modern public space plays a vital and core role in the transition towards a friendly lifestyle. However, urban planning and design guidelines in many countries’ practices have radically transformed without cultural preservation purpose. Therefore, it is necessary to design public space with local cultural wisdom demonstrated as renewable criteria considered a sustainable public space solution for smart cities. This may improve places, increasing prosperity and extending expectations of modernization in (...) many cities. This article contributes to cultural preservation dynamism in public spaces. It explores how modernist approaches to planning and design along with cultural features shaped the quality of urban space. This study uses the Banjar culture in Banjarbaru City, Indonesia as a replanned city in a rapidly developing economy, but one where largely unusable public spaces have failed to meet people’s everyday needs and aspirations. The study was performed based on extensive literature reviews, documentary analyses, morphological surveys, photographic and qualitative surveys. In general, the integration of Banjar culture into modern public space provides a better promotion understanding of identity and friendly environmental quality. (shrink)

With rapid changes in urban living today, peoples’ behavioural patterns and spatial practices undergo a constant process of adaptation and negotiation. Using “house” as a laboratory and everyday life and spatial relations of residents as a framework of analysis, the paper examines the spatial planning concepts in traditional and contemporary Iranian architecture and the associated socio-cultural practices. Discussions are drawn upon from a pilot study conducted in the city of Kerman, to investigate ways in which contemporary housing solutions (...) can better cater to the continually changing socio-cultural lifestyles of residents. Data collection for the study involved a series of participatory workshops and employed creative visual research methods, participant observation and semi structured interviews to examine the interlacing of everyday socio-spatial relations and changing perception of identity, belonging, socio-cultural and religious values and conflict. The inferences from the study showcases the emerging social and cultural needs and practices of people manifested through the complex relationship between residents, the places in which they live, and its spatial planning and organisation. For a better understanding of this complex relationship, the paper argues the need for resituating spatiality as a socio-cultural paradigm. (shrink)

Climate change poses a significant risk threatening the livelihood of people, communities, and cities worldwide. The stakes cannot be reduced to zero, so there is a constant need to re-theorize the collective action to address the climate change challenges. Doing so requires planning to reduce vulnerability to climate change. One of the most crucial challenges facing scientists, academics, citizens, and policymakers today is whether the collaborative, inclusive, and resilient climate change action can be implemented, assessed, and achieved. To respond (...) to this question, this research aims to re-theorize, de-conceptualize, and analyze the collective effort to address the climate change challenges. First, the paper conceptualizes climate change resiliency as the ability to anticipate, prepare for, and respond effectively to climate-related risks, hazards, and threats. The existing challenges toward implementing resilient and inclusive climate change action have been analyzed. The paper theorizes the urban commons and collaborative governance to theorize collective efforts. This article concludes by identifying some critical determinants for the up‐scaling of collective action to address the climate change challenges. It can be supposed that any future inclusive and resilient collective action to address climate change is based on social learning to support decision-making, emphasizing inclusion and equity, which came in line with the United Nation’s 2030 SDGs.

Through analysing different case studies in the Middle East, this section uses rooted cosmopolitanism as a theoretical lens to explore exported modernism and architecture between socialist and capitalist countries during the Cold War. This research analyses the circulation and local applications of urban development and modernisation paradigms in so-called ‘Third World’ countries. For assessing the socialist and capitalist-inspired modernisation processes in the Middle East, this chapter studies the cosmopolitan and trans-cultural architecture created by global and local influences. Comparing two (...) types of cosmopolitan architecture (socialist and capitalist) during the Cold War period in third-world contexts will help us to analyse and compare their relative rootedness and to learn from the interconnected, multifaceted, and multilayered planning transfers and architectural exportations.

Marianna Charitonidou's books discuss the problem of changes in the creation of architecture in the 20th century. The author showed representatives of four generations of architects of this period. The first group is represented by Le Corbusier and Ludwig Mies van der Rohe. The second generation was described as a group of opponents to the CIAM environment centered around the Team X grouping and the activities of Alison and Peter Smithson and Aldo van Eyck. Generation three was discussed based on (...) the work of Aldo Rossi and Giancarlo Da Carlo. Generation four, active since the 1980s, was linked to the activities of Rem Koolhaas and Bernard Tschumi.

In 1960, Kevin Lynch wrote The Image of the City, which transformed the way design professionals and social scientists dealt with the urban form and design. The Evaluative Image of the City follows the work of Lynch and further explores the role of human evaluations of the cityscape. This book describes how to assess, plan, and design the appearance of cities to please inhabitants. It presents a series of studies on evaluative images and discusses methodologies, findings, and applications to (...) design and planning at various stages. Designers, planners, and businesspeople, as well as the general public, will find this book a valuable guide for improving the image of their surroundings. (shrink)

Plato put housing second only to a secure food supply in the order of business of an emerging polis [Republic 2.369d); we argue, without quibbling over rank, that adequate housing ought to have fundamental priority, with health and education, in civil societies' planning, budgets, and legislative agendas. Something made explicit in the Platonic Laws, and often reiterated by today's poor — but as often forgotten by bureaucrats— is that human wellbeing, eudaimonia, is impossible for the homeless. That is, adequate (...) housing is valuable to human societies independently of its instrumental role in supporting the safety, health, and education of the populace. Currently, governments all too frequently end up undermining their own health and education programs as a direct result of neglecting the housing needs of the poor. Finally, we argue that governments ought now to be using the low-cost ways that already exist to provide, or to promote the provision of, better housing for their increasingly urbanized populations; further, even in those circumstances where it is necessary to subsidize housing, governments' most important role is to develop just regulatory and enforcement systems within which public- and private-sector investment can operate.

The overwhelming majority of Albania’s urban population is located in Tirana, a city with a very dynamic socio-spatial reality, resulting as an entry point for people from various origins, including multicultural rural societies, and has significant concentrations of finance and other economic activities. Urban areas demonstrate the dynamics that impact society from many angles, including those related to technology, economics, demographics, and culture, via a diverse and changed perspective. Since 1991, there has been a growing separation between classes, (...) genders, and regions, as well as between individuals and vulnerable groups, due to a lack of social protection and governmental measures for these groups and individuals, and the unrestricted power of the free market. Today, there is a noticeable improvement in the real pattern of social group concentration. This paper focuses on various divisions of social groupings in Tirana, how they are reflected in the city’s everyday life, and how they trend to the fragmentation of contemporary urban regions. In order to comprehend the change over time and transition patterns of Tirana from sites of production to places of consumption, the process method is modified by concentrating on the main stakeholders. The background of enhancing cities’ mobility and competitiveness demonstrates the interaction between different social groups and different living patterns in Tirana. The study also shows the socio-spatial pattern of the new city. The significant level of social fragmentation in Tirana is evident from analysis that only investigated a certain percentage of the city’s social groupings. The new master plans predicted in the city will help to overcome the issue. (shrink)

Our task is the preservation of historic towns. In America as in Europe historic town centers are surrounded by recent additions and suburban sprawl. It is tempting to imagine the task of preservation as protecting our historical heritage from a featureless wave of mediocrity, as the worldwide commercial civilization overwhelms local cultures. This story is familiar from the writings of Kenneth Frampton and others: sprawl, homogenization, loss of distinctive local and regional form. I want to disagree with this story. From (...) what force are we trying to save the historic towns? Might not that force have its own new kinds of order? Might that new order be already at work inside the historic towns? Are its effects only negative? I want to question a presupposition common in many discussion of historic preservation. This is the presupposition that a spatially distinct historic center belongs to a single community that possesses a unified self-consciousness and a unified aesthetic self-image. Local communities less and less correspond to bounded spatial areas, and spatial areas contain less and less homogeneous communities. There is growing a new kind of discontinuous unity, which is the theme of this essay. (shrink)
