Cross-city transfer improves prediction in label-scarce cities by leveraging labeled data from other cities, but it becomes challenging when cities adopt incompatible partitions and no ground-truth region correspondences exist. Existing approaches either rely on heuristic region matching, which is often sensitive to anchor choices, or perform distribution-level alignment that leaves correspondences implicit and can be unstable under strong heterogeneity. We propose SCOT, a cross-city representation learning framework that learns explicit soft correspondences between unequal region sets via Sinkhorn-based entropic optimal transport. SCOT further sharpens transferable structure with an OT-weighted contrastive objective and stabilizes optimization through a cycle-style reconstruction regularizer. For multi-source transfer, SCOT aligns each source and the target to a shared prototype hub using balanced entropic transport guided by a target-induced prototype prior. Across real-world cities and tasks, SCOT consistently improves transfer accuracy and robustness, while the learned transport couplings and hub assignments provide interpretable diagnostics of alignment quality.
An increasing number of modernist churches of the Evangelical Lutheran Church of Finland which were built in the 1960s and 1970s are reaching a point in their life cycle where they require extensive renovations or demolition. As church membership is falling due to secularisation, an ageing population, and immigration, the financial resources to do extensive renovations are also diminishing. Hence more and more modernist churches are threatened by demolition. Despite their relatively young age, these churches have already become meaningful for and entwined with the lives of local communities, and their removal is felt as a loss of valuable heritage. This article discusses the reasons for demolition and analyses subsequent debates in the public media. While most media attention is directed to values defined by architects and heritage professionals, the emotional and autobiographical values of the locals are less appreciated. It is argued that heritage professionals could prepare for the demolitions by adopting the framework of anticipatory grief, which acknowledges and perhaps alleviates the loss felt by the stakeholders.

Privacy and security in Smart Cities remain at constant risk due to the vulnerabilities introduced by Internet of Things (IoT) devices. The limited computational resources of these devices make them especially susceptible to attacks, while their widespread adoption increases the potential impact of security breaches. This article presents a review of security proposals aimed at protecting IoT devices in Smart City environments. The review was conducted by analyzing recent literature on device-level security, with particular emphasis on lightweight cryptography, physically unclonable functions (PUFs), and blockchain-based solutions. Findings highlight both the strengths and limitations of current approaches, as well as the need for more practical, scalable, and resource-efficient mechanisms to ensure user privacy and data protection in IoT ecosystems.

\abstract{Urban scaling theories posit that larger cities exhibit disproportionately higher levels of socioeconomic activity and human interactions. Yet, evidence from developing contexts (especially those marked by stark socioeconomic disparities) remains limited. To address this gap, we analyse a month-long dataset of 3.1~billion voice-call records from Brazil's 100 most populous cities, providing a continental-scale test of urban scaling laws. We measure interactions using two complementary proxies: the number of phone-based contacts (voice-call degrees) and the number of trips inferred from consecutive calls in distinct locations. Our findings reveal clear superlinear relationships in both metrics, indicating that larger urban centres exhibit intensified remote communication and physical mobility. We further observe that gross domestic product (GDP) also scales superlinearly with population, consistent with broader claims that economic output grows faster than city size. Conversely, the number of antennas required per user scales sublinearly, suggesting economies of scale in telecommunications infrastructure. Although the dataset covers a single provider, its widespread coverage in major cities supports the robustness of the results. We nonetheless discuss potential biases, including city-specific marketing campaigns and predominantly prepaid users, as well as the open question of whether higher interaction drives wealth or vice versa. Overall, this study enriches our understanding of urban scaling, emphasising how communication and mobility jointly shape the socioeconomic landscapes of rapidly growing cities.
Complex networks are commonly used to explore human behavior. However, previous studies largely overlooked the geographical and economic factors embedded in collective attention. To address this, we construct attention networks from time-series data for the United States and China, each a key economic power in the West and the East, respectively. We reveal a strong macroscale correlation between urban attention and Gross Domestic Product (GDP). At the mesoscale, community detection of attention networks shows that high-GDP cities consistently act as core nodes within their communities and occupy strategic geographic positions. At the microscale, structural hole theory identifies these cities as key connectors between communities, with influence proportional to economic output. Overlapping community detection further reveals tightly connected urban clusters, prompting us to introduce geographic and topic-based metrics, which show that closely linked cities are spatially proximate and topically coherent. Of course, not all patterns were consistent across regions. A notable distinction emerged in the relationship between population size and urban attention, which was evident in the United States but absent in China. Building on these insights, we integrate key variables reflecting GDP, geography, and scenic resources into regression model to cross-verify the influence of economic and geographic factors on collective user attention, and unexpectedly discover that a composite index of population, access, and scenery fails to account for cross-city variations in attention. Our study bridges the gap between economic prosperity and geographic centrality in shaping urban attention landscapes.
In the Italian context, the first law directly affecting the urban planning and building sector dates back to approximately 160 years ago, precisely Law 2248/1865. It established the administrative unification of the Kingdom of Italy, empowering municipal councils to deliberate on ‘hygiene, building and local police regulations’, and was followed a few months later by Law 2359/1865 on expropriations for public purpose. By contrast, the first regulations for the protection of artistic, historical, archaeological and ethnographic heritage (1089/1938), and natural beauty (1497/1939), are just over 80 years old. From that time onwards, the rules governing planning and design actions have been considerably enriched and developed. Hence, it is worth reflecting on the effectiveness and efficiency of a regulatory framework that has been governing territorial, urban and building transformations in an increasingly articulated and specialised manner with a view to improving the quality and sustainability of natural and anthropic habitats. Moreover, its ability to govern the ways, times and cultural and technical contents of the project production process to carry out high quality creations is worthy of consideration.
Perhaps the issue of standardisation has never been the centre of attention in all sectors of civil life as today: in public administration and scientific research, among economic operators, planners, and citizens themselves. Regulatory systems are increasingly pervasive in regulating design activity and the characteristics of works in response to a general «increase in the variety and complexity of public interests that appear worthy of protection, such as the quality of the environment, the safeguarding of the natural and historical-artistic heritage, the protection of health, the safety of persons, and security […]» (Bassanini et al., 2005). Changing interests require frequent updates to adapt regulations to rapid socio-economic, cultural, and technological changes.
The centres of regulatory production have also multiplied, breaking up into different levels and sectors of regulation, namely with multi-level (international, EU, national, regional, local), sectoral (economy, environment, territory, landscape, infrastructure, cultural heritage, health, etc.) and institutional governance structures, with corresponding different interests (public/private, collective/individual) and complicated relationships of interconnection, conditionality and/or competition (Raveraira, 2009). The scenario is even more complex, if we broaden the scope to include, in addition to prescriptive and binding rules, the vast universe of guiding principles, voluntary standards, guidelines, best practices, etc.
Moreover, also due to the nature of the legal system model of reference (civil law derived from Roman law, as opposed to the common law of English-speaking countries, founded on the binding force of practice and judgements), Italian legislation has been stratified by an anomalous number of rules, which are often not mutually coordinated, sometimes contradictory or bearing inconsistent definitions. They are either incapable of producing the desired results, or are not the cause of effects even diametrically opposed to those expected. The attempt to solve every problem through a special regulation results in limiting the free and responsible action of citizens (and planners). Indeed, as Marco Romano points out, «to reduce people’s desires to rights codified in the doctrine of planning, imposed by enlightened and pedagogical governments on rebellious citizens unaware of their own good, is to erase what makes them citizens: the diversity of their individual life projects» (Romano, 2013).
On the other hand, the discrepancy between this regulatory approach and the reality that surrounds us is evident. On Alessandro Pizzorno’s death, Fabrizio Schiaffonati recalled how, back in the 1960s, the doyen of Italian political sociology had already warned that in Italy «everything must be regulated so that everything can be conceded», pointing out that «this is still the case nowadays, more than half a century later, with good peace for the quality of the project, which is overwhelmed by constraints and contradictory procedures that are obstructive to a necessary qualitative transformation of the anthropic environment within proper time and costs» (Schiaffonati, 2019).
This hypertrophic growth of laws and regulations (a true ‘legislative inflation’ or ‘regulatory pollution’) is accompanied by their rapid variability over time, so much so that a building intervention begun within a given legislative framework risks being completed in the presence of a different regulatory framework, which would not have allowed its execution, and vice versa. Not to mention the «badly written, lengthy regulations that are difficult to read and even more difficult to apply, (which) now represent a constant factor with which even the most prepared and motivated operator must come to terms» (Gorlani, 2022), which lead to confusion and interpretative doubts. This makes bureaucratic formalities unnecessarily complex, overloads administrative action, and increases the regulatory and management costs for citizens, businesses and the public institutions themselves, including those dedicated to monitoring and control actions (which, in a context of shrinking public resources, are often the first to be lacking…).
Legal uncertainty leads to opaque, if not arbitrary decisions, facilitates corruption, increases discrimination and social conflict, and limits economic development, sometimes to the point of inhibiting it (Bassanini et al., 2005). A vulnus with dramatic effects, if it is true that certainty does not have to be of the law, but: «certainty is law, just as, vice versa, law is certainty, if it is true that law […], is constituted for the specific purpose of giving certainty, or rather: certainties» (emphasis added; Ruggeri, 2005).
The body of urban planning legislation has expanded considerably, imposing on city and regional planning new objectives and constraints aimed at protecting and improving the quality of the environment and landscape. Strategic environmental and impact assessments, regulations to limit land consumption, to increase climate resilience and to regenerate the built environment have been in use for many years now, with their rich set of analyses and tools to manage knowledge, build scenarios, compare alternatives, and quantify their effects through indicators (environmental, socioeconomic, etc.). And yet, all this does not seem to have produced the expected effects, as witnessed by the continuing degradation of urban suburbs, the continuous increase in soil erosion by new urbanisations and infrastructures, the abandonment of ‘inland areas’, and the hydrogeological instability of the most ‘fragile’ territories. Instead, by moving more and more on the level of so-called policies, planning seems to have lost its technical capacity to conform the quality of spaces, even in their cultural value and use, in a sort of throwback of illiteracy forgetting the grammatical and syntactical rules of construction of the European city. The disciplinary crisis of the plan is evident, incapable of governing land uses and built forms, as well as the quality of public space, relying, instead, on the abstraction of ‘tactical squares’ and social streets totally inadequate to determine an organic configuration of the urban structure.
There is no large city that does not have a plan for climate resilience or sustainable mobility, nor is there a major project that cannot boast top-level environmental and/or energy performance, duly certified even when it plans to replace a tree-lined park of more than 50,000 square metres with green roofs on a shopping centre (for example, San Siro in Milan). Greenwashing operations often characterise the private actions of real estate operators, in the absence of checks and controls by the public authorities.
The public works sector has long been searching for a better balance of time, cost and quality of works. «A long journey, which has allowed for advances […] and regulatory innovations during the Nineties» (Schiaffonati, 2006) and which, after thirty years of conjunctural measures (suspensions, temporary derogations, emergency decrees, special procedures and competences, variations of thresholds, etc.1) has led to the new Procurement Code (legislative decree no. 36/2023). It features a text of more than 150,000 words, to which the regulatory and procedural innovations introduced by the PNRR must be added, with the related set of regulations, guidelines, explanatory circulars, protocols and technical instructions2.
It is a seemingly unstoppable process of continuous correction and integration to reform the reform, in the absence of the indispensable monitoring activity that should, instead, verify and assess the effects of the application of the regulation to correctly finalise its amendment. Nevertheless, there has been no lack of significant precedents in this regard, as in the case of the French experimentation of the Spinetta Law on construction insurance systems3.
If we apply to the standard the historical notion of “quality as fitness for intended use” (Juran, 1951), or to the more recent notion of «the set of properties and characteristics of a product or service that provide the capacity to satisfy expressed or implicit needs» (UNI EN ISO 8402:1995), it clearly appears that the challenge to be faced concerns not so much or only regulatory and administrative simplification, or the replacement of redundant, obsolete or unjustified regulations, but precisely the “quality of regulation”. A direction undertaken since 2001 by OECD and Apec countries with a Regulatory Reform (reference criteria to ensure quality and transparency in regulatory activity), in line with the obligation to formulate rules that are conceptually and semantically precise, clear and comprehensible in the terms used, in the objectives set, in the required behaviour (Constitutional Court, ruling no. 364 of 1988) and, above all, with contents derived from consensual and shared planning (Raveraira, 2009).
Responsibility, consensus and collaboration are, I believe, the key words to possibly rethink the relationship between design and regulation. In fact, I agree with Marco Dugato’s observation in this Dossier when he argues that «the fault of normative hypertrophy cannot be attributed to the omnipotence of the regulator by itself, rather it is attributable to the contribution of the ones regulated». If it is true that architectural design is constrained by regulations, it certainly cannot be mechanically determined by them for mere reasons of conformity. Conversely, as Maria Chiara Torricelli emphasises again in the Dossier, the norm is a tool that provides valid and shared knowledge to the project; and the project itself, as a projective activity, contributes proactively to its definition. There are many examples spanning technical directives regulating the implementation cycles of the INA Casa, the result of design research in support of the political project, and the various procedural and meta design regulations derived from research in the Architectural Technology Field. Such design experiences have unfolded in an experimental manner, in derogation of the regulations and leading to their renewal.
Instead, deductive design approaches seem to prevail today, due to the growing availability of algorithmic procedures that do not merely support the design process, but develop it in an almost automated manner through conditioning and prevailing indicators and parameters. These tools legitimise choices where conformity to the standard acts as a screen for the assumption of precise responsibilities.
There is a conceptual and operational reversal with respect to creative, responsibly inductive design action, which experiments and innovates, putting the principles of adequate performance and compliance with needs over the criteria of formal conformity. This is evident in the relationship between technical regulations and techno-typological innovation for evolutions that move the parameters of regulatory congruity “forward”, but sometimes even “sideways”. This also counteracts the phenomena of norm obsolescence.
In consideration of the pervasiveness of the regulatory systems that rule design action, it is, finally, disturbing to observe the very limited importance assigned to this subject in the education of new designers. The didactics of design, which have long been the focus of Architecture studies, rarely envisage a structured discussion on regulatory and normative aspects, leaving them to the discretion of professors. Hence, at the end of the course, a large proportion of students have never heard about the Code of Procurement, environmental impact assessment or minimum environmental criteria… Whereas it is, instead, essential to solicit, from the first year, critical attention to the normative paradigm, also for the ethical, social and professional responsibilities it entails, and to encourage the assumption of norms and constraints as factors that nourish the entire design process. The norm thus becomes a «tool for guiding and controlling design choices», which as such «must be assumed in the organisation of the starting data» (Del Nord, 1992).
Not to mention the need for qualifying training programmes, as Mario Avagnina points out, so that all those involved in the process, particularly public clients, are able to carry out their tasks. The objective is far from being achieved, and «necessarily passes through the training of the figures involved, starting with the RUPs». Figures characterised not only by technical knowledge of the building process and its rules, but also by a culture of standards and conscious responsibility that can only derive from a design practice, which is continually verified in the real context, and by design actions based on an experimental method that aims to face the issues of society. Figures characterised not only by technical know-how of the building process and its rules, but also by a culture of standards and conscious responsibility, which can only derive from a practice continually verified by comparison with reality, and by design actions marked by an experimental method that finds its arguments in taking on the problems of society.

This paper presents a 1/10th scale mini-city platform used as a testing bed for evaluating autonomous and connected vehicles. Using the mini-city platform, we can evaluate different driving scenarios including human-driven and autonomous driving. We provide a unique, visual feature-rich environment for evaluating computer vision methods. The conducted experiments utilize onboard sensors mounted on a robotic platform we built, allowing them to navigate in a controlled real-world urban environment. The designed city is occupied by cars, stop signs, a variety of residential and business buildings, and complex intersections mimicking an urban area. Furthermore, We have designed an intelligent infrastructure at one of the intersections in the city which helps safer and more efficient navigation in the presence of multiple cars and pedestrians. We have used the mini-city platform for the analysis of three different applications: city mapping, depth estimation in challenging occluded environments, and smart infrastructure for connected vehicles. Our smart infrastructure is among the first to develop and evaluate Vehicle-to-Infrastructure (V2I) communication at intersections. The intersection-related result shows how inaccuracy in perception, including mapping and localization, can affect safety. The proposed mini-city platform can be considered as a baseline environment for developing research and education in intelligent transportation systems.
This paper explores the application of automated planning to automated theorem proving, which is a branch of automated reasoning concerned with the development of algorithms and computer programs to construct mathematical proofs. In particular, we investigate the use of planning to construct elementary proofs in abstract algebra, which provides a rigorous and axiomatic framework for studying algebraic structures such as groups, rings, fields, and modules. We implement basic implications, equalities, and rules in both deterministic and non-deterministic domains to model commutative rings and deduce elementary results about them. The success of this initial implementation suggests that the well-established techniques seen in automated planning are applicable to the relatively newer field of automated theorem proving. Likewise, automated theorem proving provides a new, challenging domain for automated planning.
This article seeks to explain the development of urban ethnography and the successful careers of its practitioners, evident in the 1990s but not in the 1920s and 1940s, by examining several factors: the dispersion of University of Chicago students trained in fieldwork, the expansion of the graduate population, the urban revolts of the 1960s, the proliferation of urban research centres, and the growth of anthropologists' interest in 'urban' issues. The article thus provides a better understanding of what is usually imprecisely described as a consequence of the movement of ideas, by following people and institutional developments.

This article documents the deployment of a new metropolitan critique through the ethnography of contestation in action in a neighbourhood in Nantes, France - Le Bois Hardy, in Bas Chantenay. It analyzes the make-up of a collective, without neglecting its internal differences, and its non-univocal relations with public actors. Using a typology of urban environmentalisms, we show the dynamics of a non-homogeneous group, the supports and activities that allow a credible and tangible critique of urban planning. Although there remains an artistic critique of the densification operations at work in the city centre, we rather examine a procedural critical activity that questions, on the side of the collective, the ways of apprehending the general interest. Starting from a singular mobilization, this article goes into the details of an emerging metropolitan critique in the making.

Resumen
Las ciudades pequeñas y medias son un activo fundamental de los territorios y, aunque con un papel renovado hoy, siguen siendo, como históricamente, claves para el desarrollo equilibrado de nuestras regiones y sus sociedades. Aunque en torno a dicho papel pueden realizarse multitud de análisis, muy diversos, la articulación funcional es una de las dimensiones más interesantes a través de la cual comprobar cómo estas ciudades contribuyen, por su posición socioespacial intermedia, a la cohesión territorial.
La red polinuclear de nodos urbanos del litoral centro-oriental de Andalucía, entre las aglomeraciones urbanas de Málaga y la Costa del Sol y de Almería y el Poniente, constituye un interesante caso de estudio por ser escenario de la aparición e intensificación de una serie de procesos de gran impacto sobre las estructuras demográficas y económicas precedentes sin que esto haya supuesto una disminución de sus funciones de intermediación históricas. A través del análisis de la articulación territorial de esta red urbana, con Vélez-Málaga, Motril y Adra a la cabeza demográficamente, se defiende la necesidad de atender a las ciudades pequeñas y medias a la hora de plantear estrategias futuras de planificación y desarrollo territorial, reivindicando y considerando su necesario protagonismo.
Abstract
Small and medium-sized cities are a fundamental asset of territories and, although with a renewed role today, they remain, as historically, key to the balanced development of our regions and their societies. Although a multitude of diverse analyses can be carried out on this role, functional articulation is one of the most interesting dimensions through which to verify how these cities contribute, due to their intermediate socio-spatial position, to territorial cohesion. The polynuclear network of urban nodes on the central-eastern coast of Andalusia, between the urban agglomerations of Malaga and the Costa del Sol and Almeria and the Poniente, is an interesting case study because it is the scene of the appearance and intensification of a series of processes with a great impact on the previous demographic and economic structures without this having led to a reduction in their historical intermediary functions. Through the analysis of the territorial articulation of this urban network, with Vélez-Málaga, Motril and Adra at the demographic forefront, the need to pay attention to small and medium-sized towns when considering future strategies for territorial planning and development is defended, reaffirming and considering their necessary prominence.

This paper proposes the use of an on-demand, ride hailed and ride-Shared Autonomous Vehicle (SAV) service as a feasible solution to serve the mobility needs of a small city where fixed route, circulator type public transportation may be too expensive to operate. The presented work builds upon our earlier work that modeled the city of Marysville, Ohio as an example of such a city, with realistic traffic behavior, and trip requests. A simple SAV dispatcher is implemented to model the behavior of the proposed on-demand mobility service. The goal of the service is to optimally distribute SAVs along the network to allocate passengers and shared rides. The pickup and drop-off locations are strategically placed along the network to provide mobility from affordable housing, which are also transit deserts, to locations corresponding to jobs and other opportunities. The study is carried out by varying the behaviors of the SAV driving system from cautious to aggressive along with the size of the SAV fleet and analyzing their corresponding performance. It is found that the size of the network and behavior of AV driving system behavior results in an optimal number of SAVs after which increasing the number of SAVs does not improve overall mobility. For the Marysville network, which is a 9 mile by 8 mile network, this happens at the mark of a fleet of 8 deployed SAVs. The results show that the introduction of the proposed SAV service with a simple optimal shared scheme can provide access to services and jobs to hundreds of people in a small sized city.
Various stakeholders with different backgrounds are involved in Smart City projects. These stakeholders define the project goals, e.g., based on participative approaches, market research or innovation management processes. To realize these goals often complex technical solutions must be designed and implemented. In practice, however, it is difficult to synchronize the technical design and implementation phase with the definition of moving Smart City goals. We hypothesize that this is due to a lack of a common language for the different stakeholder groups and the technical disciplines. We address this problem with scenario-based requirements engineering techniques. In particular, we use scenarios at different levels of abstraction and formalization that are connected end-to-end by appropriate methods and tools. This enables fast feedback loops to iteratively align technical requirements, stakeholder expectations, and Smart City goals. We demonstrate the applicability of our approach in a case study with different industry partners.
Abstract : Basuki Rahmat Street is a National Road with a primary-arterial-function based on the Regional Master Plan of Palu City 2010-2030. The area is focused as a trade and service area which attracts visitors to have economic and social activities. Therefore, each section of the road has other traffic performance. The research was conducted in three road segments: Grand Hero Supermarket, Samsung store, and BCA Bank, and Star Kitchen Electronic Center based on traffic generation of business activity. The study aims to understand Basuki Rahmat street's performance and its activities in each segment. A survey was conducted periodically (early, middle, and end of the month) by taking a workday and a holiday for each period, from 09.00-22.00 WITA. The evaluation method was based on the Indonesian Highway Capacity Manual (IHCM) 1997 urban area on peak hour. The result showed that the Road Segmentation Method (RMS) of Basuki Rahmat street has 0.37 degrees of Saturation (DS) and was included in a B level of service. The differences between DS-RMS and DS on each segment were 0.04. The road segmentation method should be considered to assess the traffic performance of the road link.

In this paper, a mathematical model is proposed to analyze the dynamic behavior of COVID-19. Based on inter-city networked coupling effects, a fractional-order SEIHDR system with the real-data from 23 January to 18 March, 2020 of COVID-19 is discussed. Meanwhile, hospitalized individuals and the mortality rates of three types of individuals (exposed, infected and hospitalized) are firstly taken into account in the proposed model. And infectivity of individuals during incubation is also considered in this paper. By applying least squares method and predictor-correctors scheme, the numerical solutions of the proposed system in the absence of the inter-city network and with the inter-city network are stimulated by using the real-data from 23 January to $18-m$ March, 2020 where $m$ is equal to the number of prediction days. Compared with integer-order system ($α=0$), the fractional-order model without network is validated to have a better fitting of the data on Beijing, Shanghai, Wuhan, Huanggang and other cities. In contrast to the case without network, the results indicate that the inter-city network system may be not a significant case to virus spreading for China because of the lock down and quarantine measures, however, it may have an impact on cities that have not adopted city closure. Meanwhile, the proposed model better fits the data from 24 February to 31, March in Italy, and the peak number of confirmed people is also predicted by this fraction-order model. Furthermore, the existence and uniqueness of a bounded solution under the initial condition are considered in the proposed system. Afterwards, the basic reproduction number $R_0$ is analyzed and it is found to hold a threshold: the disease-free equilibrium point is locally asymptotically stable when $R_0\le 1$, which provides a theoretical basis for whether COVID-19 will become a pandemic in the future.
