Stuck in place. Patterns of inequality relating social classes and street centrality in Bogotá (Colombia)
This study examines how street centrality relates to socio-economic conditions in Bogotá, Colombia, using data at the urban block level. Centrality metrics – both global and local – are calculated through Multiple Centrality Assessment. Results reveal contrasting spatial patterns: middle and higher classes concentrate in areas with high global centrality, offering long-range connectivity, while lower classes cluster in areas with high local centr…
Urban form and socioeconomic deprivation in Isfahan
Studies on urban deprivation date back to the 19 th Century but remain important today due to rising levels of inequality and social segregation. However, while social causes of deprivation have been investigated, the role of the built environment remains neglected. Existing studies either provide broad coverage at the expense of detailed morphological descriptions or offer meticulous accounts of small-scale areas without capturing the broader co…
EO + Morphometrics
Earth Observation (EO)-based mapping of cities has great potential to detect patterns beyond the physical ones. However, EO combined with the surge of machine learning techniques to map non-physical, such as socioeconomic, aspects directly, goes to the expense of reproducibility and interpretability, hence scientific validity. In this paper, we suggest shifting the focus from the direct detection of socioeconomic status from raw images through im…
Urban form character and Airbnb in Amsterdam (NL)
Proliferation of Short Term Rental (STR) in cities has generated considerable debate as it was found associated with negative externalities, such as gentrification. Nonetheless, it signals urban qualities working as attractors at different geographical scales. STRs’ relation with urban form remains largely understudied. In this paper, we explore how urban form relates to STRs registered by the Airbnb platform in Amsterdam (NL). First, we identify…
Urban form and Covid-19 cases and deaths in Greater London
The COVID-19 pandemic generated a considerable debate in relation to urban density. This is an old debate, originated in mid 19th century’s England with the emergence of public health and urban planning disciplines. While popularly linked, evidence suggests that such relationship cannot be generally assumed. Furthermore, urban density has been investigated in a spatially coarse manner (predominantly at city level) and never contextualised with ot…
Methodological foundation of a numerical taxonomy of urban form
Cities are complex products of human culture, characterised by a startling diversity of visible traits. Their form is constantly evolving, reflecting changing human needs and local contingencies, manifested in space by many urban patterns. Urban morphology laid the foundation for understanding many such patterns, largely relying on qualitative research methods to extract distinct spatial identities of urban areas. However, the manual, labour-inte…

Urban Morphometrics and the Intangible Uniqueness of Tangible Heritage. An Evidence-Based Generative Design Experiment in Historical Kochi (In)
Asia is urbanising rapidly. Current urbanisation practices often compromise sustainability, prosperity, and local quality of life while context-sensitive alternatives show very limited impact. A third way is necessary to integrate mass-production, heritage, and human values. As part of UNICITI’s initiative, A Third Way of Building Asian Cities, we propose a scalable and replicable methodology which captures unique morphological traits of urban ty…
Measuring urban form
Unprecedented urbanisation processes characterise the Great Acceleration, urging urban researchers to make sense of data analysis in support of evidence-based and large-scale decision-making. Urban morphologists are no exception since the impact of urban form on fundamental natural and social patterns (equity, prosperity and resource consumption’s efficiency) is now fully acknowledged. However, urban morphology is still far from offering a compre…
H eghnar Z eitlian W atenpaugh . The Missing Pages
In 1256, Toros Roslin completed an illuminated copy of a set of the Zeytun Gospels that had been commissioned and paid for by the Catholicos of the Armenian Church, Constantine I (1221–67). In The Missing Pages: The Modern Life of a Medieval Manuscript from Genocide to Justice, Heghnar Zeitlian Watenpaugh traces the evolution of the status of this manuscript from Constantine’s private property to a local liturgical relic to a national artifact th…

Jack Tannous. The Making of the Medieval Middle East
In the ambitious The Making of the Medieval Middle East: Religion, Society, and Simple Believers, Jack Tannous foregrounds the “simple believer” in the social history of the Middle East between the fifth and ninth centuries c.e. He reminds us that the learned elite upon whose works much modern scholarship relies were not representative of the majority of believers, whether Christian or Muslim. Instead, these believers were composed of the “simple…
On the origin of spaces
The modern discipline of urban morphology gives us a ground for the comparative analysis of cities, which increasingly includes specific quantitative elements. In this paper, we make a further step forward towards the definition of a general method for the classification of urban form. We draw from morphometrics and taxonomy in life sciences to propose such method, which we name ‘urban morphometrics’. We then test it on a unit of the urban landsc…
Form and urban change – An urban morphometric study of five gentrified neighbourhoods in London
Research in Urban Morphology has long been exploring the form of cities and their changes over time, especially by establishing links with the parallel dynamics of these cities’ social, economic and political environments. The capacity of an adaptable and resilient urban form to provide a fertile environment for economic prosperity and social cohesion is at the forefront of discussion. Gentrification has emerged in the past few decades as an impo…
Street networks and street- blocks in the city centre of Tripoli
The results of an analysis of the urban form of central Tripoli, Libya are presented. Three cases from different morphological periods are compared: the Old Town (pre- modern), the Italian Quarter (colonial) and the Garden Suburb (early- Modernist). Two sets of descriptive indices that relate to street network and street- block structure are applied to measure quantitatively the urban fabric of the three selected cases and explore their distinct …
Armeno-Latin Intellectual Exchange in the Fourteenth Century
This essay examines the scholarly interaction and competition between the Armenian and Latin intellectual traditions in the fourteenth century. During the course of the century, Franciscan and Dominican missionaries successfully converted a number of Armenians to Roman Catholicism. In order to do so, they brought a significant number of texts that were translated into Armenian. The Aristotelian focus of the Dominican tradition in particular const…
Seta B. Dadoyan. The Armenians in the Medieval Islamic World
The current volume by Seta B. Dadoyan consists of two parts, the first examines Erznka (Erzincan) as a paradigmatic case study for the analysis of the interaction between Armenian and Muslim communities in Eastern Anatolia. The second presents images of Muḥammad and Islam in Armenian literature, particularly in the polemical literature of the fourteenth century. The volume also reproduces the introductions to the first two volumes in the series a…
Alterations in scale
This paper presents a morphological study of 100 main street networks from urban areas around the world. An expansion in the scale of main street networks was revealed using a unique heuristic visual method for identifying and measuring the lengths of main street segments from each of the study areas. Case studies were selected and grouped according to corresponding urban design paradigms, ranging from antiquity to present day. This research show…
Elementary processes governing the evolution of road networks
Urbanisation is a fundamental phenomenon whose quantitative characterisation is still inadequate. We report here the empirical analysis of a unique data set regarding almost 200 years of evolution of the road network in a large area located north of Milan (Italy). We find that urbanisation is characterised by the homogenisation of cell shapes, and by the stability throughout time of high-centrality roads which constitute the backbone of the urban…
Street Centrality and the Location of Economic Activities in Barcelona
The paper examines the geography of three street centrality indices and their correlations with various types of economic activities in Barcelona, Spain. The focus is on what type of street centrality (closeness, betweenness and straightness) is more closely associated with which type of economic activity (primary and secondary). Centralities are calculated purely on the street network by using a multiple centrality assessment model, and a kernel…

Street Centrality and Densities of Retail and Services in Bologna, Italy
This paper examines the relationship between street centrality and densities of commercial and service activities in the city of Bologna, northern Italy. Street centrality is calibrated in a multiple centrality assessment model composed of multiple measures such as closeness, betweenness, and straightness. Kernel density estimation is used to transform datasets of centrality and activities to one scale unit for analysis of correlation between the…

Centrality measures in spatial networks of urban streets
We study centrality in urban street patterns of different world cities represented as networks in geographical space. The results indicate that a spatial analysis based on a set of four centrality indices allows an extended visualization and characterization of the city structure. A hierarchical clustering analysis based on the distributions of centrality has a certain capacity to distinguish different classes of cities. In particular, self-organ…
The network analysis of urban streets
The Network Analysis of Urban Streets
The network metaphor in the analysis of urban and territorial cases has a long tradition, especially in transportation or land-use planning and economic geography. More recently, urban design has brought its contribution by means of the ‘space syntax’ methodology. All these approaches-though under different terms like ‘accessibility’, ‘proximity’, ‘integration’ ‘connectivity’, ‘cost’, or ‘effort’-focus on the idea that some places (or streets) ar…
Translation And Transformation
Although Greco-Roman language and literature remained the dominant force in the center of the Christian world, towards the periphery there now existed Armenian, Coptic, Ethiopic, Georgian, and Syriac literatures. The literary emergence of local tongues changed the fundamental relationship between culture and language in those areas. The task of converting Armenians to Christianity began immediately after the conversion of King Trdat at the beginn…
The Reception and Influence of the Corpus of Works Attributed to Dionysius the Areopagite in the Medieval Armenian Spiritual Tradition
T he corpus of works attributed to Dionysius the Areopagite1 was first translated into Armenian by Step'anos Siwnec'i with the assistance of Dawit' Hiwpatos in Constantinople between 712 and 717.2Along with the corpus, Step'anos and Dawit' rendered the scholia attributed to Maximus 1. Abbreviations have been used for the following Dionysian texts: HH^Heavenly Hierarchy
The Armenian Episcopacy in Mamluk Jerusalem in the Aftermath of the Council of Sis (1307)
From the earliest days of Christianity in Armenia, Jerusalem was an important centre of pilgrimage, culture, and faith. An Armenian hierarchy free from the authority of the Imperial Greek church had existed in Jerusalem possibly from the time of Justinian and an Armenian episcopacy from the time of the Arab conquests. According to Armenian tradition, first recorded in M. Č‘amč‘ian's History of the Armenians , in 1311 Bishop Sargis of Jerusalem (s…
