Agriculture as a Catalyst for New Forms of Urban Habitat in Residential Architecture. A Case of Multi-Family and Mixed Housing Estates from 2010–2021 – European, American and Asian Context

Abstract The article presented herein constitutes a research summary on urban, residential housing forms connected with agriculture developed in the years 2010–2021 throughout Northern America, Asia and Europe. The presented research was aimed at a comprehensive and comparative analysis of contemporary architecture, concerning new spatial phenomenon, analysing both the external form and the internal structure – formal and functional, of the resulting housing development. The method of global sampling was chosen as the possible examples of housing estates related to greenery or agriculture are spread worldwide. The paper aims to identify the main trends in creating a new form of urban living and to find the main points generating changes in the structure of buildings in connection with urban agriculture. Seven case studies were selected for the study, relating to both conceptual and already completed projects, showing a number of differences between the theoretical approach and its implementation, both in terms of the adopted assumptions and parameters of the obtained space in relation to housing estates combining architecture and greenery from that period. Case studies from Asia, North America and Europe created a background for comparison with the first Polish example of this type of development, located in Poznań.

Integrating macroeconomics and economic geography: the neoclassical growth model in spatial general equilibrium

ABSTRACT The neoclassical growth model and the Roback model of spatial general equilibrium (SGE) are integrated to study the joint determination of macroeconomic phenomena (gross domestic product (GDP) and the rate of interest) and spatial economic phenomena (the spatial distribution of gross regional product (GRP), employment and capital). If internal capital mobility is perfect and regional savings rates are homogeneous, GDP depends on SGE, but SGE does not depend on GDP. If saving rates are spatially heterogeneous, GDP and the rate of interest depend on SGE, but SGE does not depend on the rate of interest and GDP. If in addition capital is imperfectly mobile, macroeconomic outcomes such as GDP, the rate of interest and SGE are jointly determined. In general, therefore, the dichotomy between macroeconomics and economic geography breaks down.

Fsr: An R package for fuzzy spatial data handling

AbstractSpatial libraries are core components in many geographic information systems, spatial database systems, and spatial data science projects. These libraries provide the implementation of spatial type systems that include spatial data types and a large diversity of geometric operations. Their focus relies on handling crisp spatial objects, which are characterized by an exact location and a precisely defined extent, shape, and boundary in space. However, there is an increasing interest in analyzing spatial phenomena characterized by fuzzy spatial objects, which have inexact locations, vague boundaries, and/or blurred interiors. Unfortunately, available spatial libraries do not provide support for fuzzy spatial objects. In this article, we describe the R package named fsr, which is based on the Spatial Plateau Algebra and is publicly available at https://cran.r‐project.org/package=fsr. Our tool provides methods for building fuzzy spatial objects as spatial plateau objects and conducting exploratory spatial data analysis by using fuzzy spatial operations.

Synthetically non-Hermitian nonlinear wave-like behavior in a topological mechanical metamaterial

Topological mechanical metamaterials have enabled new ways to control stress and deformation propagation. Exemplified by Maxwell lattices, they have been studied extensively using a linearized formalism. Herein, we study a two-dimensional topological Maxwell lattice by exploring its large deformation quasi-static response using geometric numerical simulations and experiments. We observe spatial nonlinear wave-like phenomena such as harmonic generation, localized domain switching, amplification-enhanced frequency conversion, and solitary waves. We further map our linearized, homogenized system to a non-Hermitian, nonreciprocal, one-dimensional wave equation, revealing an equivalence between the deformation fields of two-dimensional topological Maxwell lattices and nonlinear dynamical phenomena in one-dimensional active systems. Our study opens a regime for topological mechanical metamaterials and expands their application potential in areas including adaptive and smart materials and mechanical logic, wherein concepts from nonlinear dynamics may be used to create intricate, tailored spatial deformation and stress fields greatly transcending conventional elasticity.

Evaluation of cut-off values in the control of land take in Italy towards the SDGs 2030

Over the last few years, land take monitoring in Europe and in Italy has become increasingly accurate and detailed owing to improved technologies that help acquire and make available free, easily accessible and high-resolution data. Nevertheless, the key issue is controlling this phenomenon, long considered pathological in its current form and scale, in order to mitigate / reverse it and achieve the 2030 containment targets set in international guidelines. To attain these results, firm regulatory action is certainly needed, underpinned by thresholds and reference limits to regulate the development of transformation activities planned by local authorities. In 2015, the United Nations Global Agenda for Sustainable Development Goals (SDGs) put forward a parameter for this purpose, namely the "Ratio of land consumption rate to population growth rate" (11.3.1 LCRPGR). It monitors the ratio between the extent of urban development and demographic dynamics in spatial-administrative units in order to link the growth of urbanized areas to actual population growth. This paper sets out a reconnaissance experiment to identify LCRPGR cut-off that can be used in legislation in relation to life quality indicators calculated repeatedly for Italy at the provincial level. The conclusions highlight the considerable difficulty inherent in identifying normative thresholds for the containment of negative spatial and social phenomena, and the need to develop scientific methods that are more reliable and robust than what is present in current practice.

Spaces of Displacement on the Island of Imbros/Gökçeada

This article investigates spaces of displacement within the context of Imbros, employing it as a case study to provide a novel perspective on the global phenomenon of displacement. Imbros/Gökçeada is a Turkish island in the Aegean Archipelago, currently inhabited by Turkish citizens from the mainland plus an indigenous community known as Rums or Asia Minor Greeks—an ethnic group who have faced waves of systematic displacement from the island during the 20th century since the demise of the Ottoman Empire. While the displacement of Imbrian Rums intensified between the period 1963 and 1980, the island simultaneously began to accommodate a growing number of Turkish residents, most of whom were emplaced by the Turkish authorities into the state-built villages on Imbros. Since the late 1990s, however, a return movement of the displaced Rum community to Imbros has gradually emerged through the revitalization of several Rum rituals on the island. As a result of these multiple temporal and spatial layers of displacement witnessed on Imbros, the question of how to better understand the phenomenon of displacement arose. To that end, the concept of positionality is deployed as a lens through which to analyze the various phases and spaces of displacement as they have occurred on Imbros itself, and from this, I produce the observation that the spatial phenomenon of displacement on Imbros is actually an entanglement of displacement, emplacement, and return (re-emplacement).

A Comprehensive Evaluation Framework of Water-Energy-Food System Coupling Coordination in the Yellow River Basin, China.

For mankind's survival and development, water, energy, and food (WEF) are essential material guarantees. In China, however, the spatial distribution of WEF is seriously unbalanced and mismatched. Here, a collaborative governance mechanism that aims at nexus security needs to be urgently established. In this paper, the Yellow River Basin in China with a representative WEF system, was selected as a case. Firstly, a comprehensive framework for WEF coupling coordination was constructed, and the relationship and mechanism between them were analyzed theoretically. Then, we investigated the spatiotemporal characteristics and driving mechanisms of the coupling coordination degree (CCD) with a composite evaluation method, coupling coordination degree model, spatial statistical analysis, and multiscale geographic weighted regression. Finally, policy implications were discussed to promote the coordinated development of the WEF system. The results showed that: 1) WEF subsystems showed a significant imbalance of spatial pattern and diversity in temporal changes; 2) the CCD for the WEF system varied little and remained at moderate coordination. Areas with moderate coordination have increased, while areas with superior coordination and mild disorder have decreased. In addition, the spatial clustering phenomenon of the CCD was significant and showed obvious characteristics of polarization; and 3) the action of each factor is self-differentiated and regionally variable. For different factors, GDP per capita was of particular importance, which contributed most to the regional development's coupling coordination. For different regions, GDP per capita, average yearly precipitation, population density, and urbanization rate exhibited differences in geographical gradients in an east-west direction. The conclusion can provide references for regional resource allocation and sustainable development by enhancing WEF system utilization efficiency.

Spatio-temporal intention learning for recommendation of next point-of-interest

ABSTRACT Next point-of-interest (POI) recommendation has been applied by many internet companies to enhance the user travel experience. Recent research advocates deep-learning methods to model long-term check-in sequences and mine mobility patterns of people to improve recommendation performance. Existing approaches model general user preferences based on historical check-ins and can be termed as preference pattern models. The preference pattern is different from the intention pattern, in that it does not emphasize the user mobility pattern of revisiting POIs, which is a common behavior and kind of intention for users. An effective module is needed to predict when and where users will repeat visits. In this paper, we propose a Spatio-Temporal Intention Learning Self-Attention Network (STILSAN) for next POI recommendation. STILSAN employs a preference-intention module to capture the user’s long-term preference and recognizes the user’s intention to revisit some specific POIs at a specific time. Meanwhile, we design a spatial encoder module as a pretrained model for learning POI spatial feature by simulating the spatial clustering phenomenon and the spatial proximity of the POIs. Experiments are conducted on two real-world check-in datasets. The experimental results demonstrate that all the proposed modules can effectively improve recommendation accuracy and STILSAN yields outstanding improvements over the state-of-the-art models.

Agency after the Subject: Beckett with Merleau-Ponty

Abstract: In Beckett and Embodiment , Amanda Dennis argues for an ecological rethinking of the concept of agency in Beckett, offering a powerful conceptual framework by which to reorganize poststructuralist, posthumanist and new materialist concerns. The book's central claim is that in his life-long engagement with embodiment Beckett invites us to disarticulate the concept of agency from intentionality and to redistribute it onto a space shaped by what Merleau-Ponty calls the body-subject. Beckett's prose reimagines agency as such a spatial phenomenon—irreducible to individual will and untethered from old mind-matter dichotomies. In developing this idea, Dennis reinvigorates the debate on agency in contemporary criticism by shifting the focus from questions of will, desire, and intention to figures of embodiment and lived space.

Multi-scale analysis of China's transportation carbon emissions based on nighttime light data.

This study explores the spatial and temporal evolution characteristics of transportation carbon emissions from multiple scales. Based on the integrated DMSP/OLS-NPP/VIIRS nighttime light data, a transportation carbon emission estimation model was constructed, and the spatial and temporal evolution characteristics of transportation carbon emissions in 30 provinces and some counties in China from 2000 to 2019 were analyzed. The main findings are as follows: (1) The goodness-of-fit of the estimation model improved from 51.2 to 87.15% by introducing the GDP variables. (2) At the provincial scale, the provinces with high carbon emissions from transportation were mainly distributed in the eastern region, with the highest value increasing from 19,171.6 million tons in 2000 to 71,545.98 million tons in 2019. The spatial distribution has a significant and positive spatial spillover effect, and the H-H aggregation was mainly distributed in the east-central region, showing a trend of expansion from the coast to the inland. Trend analysis showed that Shandong, Guangdong, Shanghai, and Jiangsu were areas with a rapid growth of high carbon emissions. (3) The county scale displayed a northeast-southwest evolutionary pattern, with the center of gravity in Henan. The spatial distribution showed a significant spatial agglomeration phenomenon. Trend analysis indicated that the transportation carbon emissions in 184 counties need to be controlled urgently, which was the focus of carbon emission reduction. This paper theoretically enriches the measurement method of transportation carbon emissions and overcomes the problem of insufficient spatial information of statistical data. In practice, it provides a scientific basis for accurate emission reduction and low-carbon development of transportation.

Factors Influencing the Coordinated Development of Urbanization and Its Spatial Effects: A Case Study of Beijing-Tianjin-Hebei Region

The purpose of the coordinated development of urbanization is to achieve the coordination of the internal subsystems of urbanization and the spatial coordination within the region. The coordinated development level of urbanization and its spatial effect are affected by many factors. Based on the influence mechanism of coordinated development of urbanization, in this study, the evaluation index system of coordinated development of urbanization and the analysis of influencing factors are constructed respectively. The coupling coordination model, fixed effect model and spatial lag model are used to analyze the coordinated development level and influencing factors of urbanization in Beijing-Tianjin-Hebei region, and the changes of influencing factors before and after the spatial effects are compared. The results are as follows: although the coordinated development level of urbanization in Beijing-Tianjin-Hebei region shows a trend of increasing year by year, the spatial differentiation phenomenon is becoming more and more obvious. In this process, the internal and external influencing factors of coordinated development of urbanization play a decisive role. In addition, after the spatial effect is included, the significance level of the influencing factors has changed, and the promotion effect on the coordinated development of urbanization is reduced. The performance is as follows: there is insufficient population transfer and employment among regions, low spatial spillover effect of economic development, strong dependence on land finance, expansion of habitat destruction and low degree of governance coordination, imbalance between public resource allocation and public service supply, lack of unified market-oriented environment and strong government intervention. The key points of future policies and reforms are as follows: under the guidance of the national strategic thinking, we should deepen the reform of the administrative system of the government, actively break through the institutional obstacles restricting the coordinated development of urbanization, continuously optimize the state of the urbanization system and form a joint force of coordinated development.

Colonialism, Migration and the Emergence of Urban Spaces in Colonial Nigeria

Arguably, urbanisation, which entails spatial, social, and temporal phenomena, is a social process describing how cities grow and societies become more complex. From this point of view, urbanisation is not a new phenomenon in Nigeria in particular and Africa in general. The process of urbanisation in Nigeria began in the pre-colonial period and continued during the colonial and post-colonial periods. However, the factors or conditions that facilitated urbanisation in each historical epoch of urbanisation in Nigeria have changed over time. This paper interrogates the effect of colonialism on the emergence of urban spaces in Nigeria between 1900 and 1960. It argues that migration, which constituted one of the main drivers of the emergence of urban spaces in Nigeria during this period, was promoted by the introduction of the British colonial policy of the administration. The main trend of internal migration during colonial Nigeria examined in the paper involves a drift from the rural areas and the lesser towns to the new urban centres of commerce and administration which developed in response to the establishment of formal colonial rule. This trend of internal migration was witnessed in different parts of Nigeria such as Lagos, Ibadan, Ogbomoso, Osogbo, Benin City (all in Western Nigeria); Onitsha, Enugu, Calabar, Port Harcourt (all in Eastern Nigeria); Kano, Jos, Makurdi, Zaria, Sokoto and Kaduna (all in Northern Nigeria) between 1900 and 1960. It concludes that the physical spaces in these cities have had a fundamental significance for the host communities, migrants and for host/migrant relations.

High Latitude Ionospheric Gradient Observation Results from a Multi-Scale Network.

In this article, a cluster comprised of eight Continuously Operating Reference Station (CORS) receivers surrounding five supplemental test stations located on much shorter baselines is used to form a composite multi-scale network for the purpose of isolating, extracting, and analyzing ionospheric spatial gradient phenomena. The purpose of this investigation is to characterize the levels of spatial decorrelation between the stations in the cluster during the periods with increased ionospheric activity. The location of the selected receiver cluster is at the auroral zone at night-time (cluster centered at about 69.5° N, 19° E) known to frequently have increased ionospheric activity and observe smaller size of high-density irregularities. As typical CORS networks are relatively sparse, there is a possibility that spatially small-scale ionospheric delay gradients might not be observed by the network/closest receiver cluster but might affect the user, resulting in residual errors affecting system accuracy and integrity. The article presents high level statistical observations based on several hundred manually validated ionospheric spatial gradient events along with low level analysis of specific events with notable temporal/spatial characteristics.

SPATIAL CLUSTERING PHENOMENA OF COVID-19 CASES IN SELANGOR: A HOTSPOT ANALYSIS AND ORDINARY LEAST SQUARES METHOD

Abstract. An increase in number of Coronavirus disease 2019 (COVID-19) cases will lead to more cluster discovery in Malaysia. Furthermore, with the increasing population, city growth, workplace income needs, high-risk groups, and other relevant factors can contribute to the formation of the new clusters. The cluster distribution of the disease could be seen by mapping and spatial analysis to understand their spatial phenomena of the disease dynamics. The purpose of the study is to analyse the spatial distribution of COVID-19 cluster cases in Selangor for year 2020. Two objectives of the study are i) to determine the hotspot location of the COVID- 19 cluster, and ii)to examine the spatial distribution of the factors affecting the COVID-19 cluster. The data processing was conducted using hotspot analysis and ordinary least squares (OLS) in ArcGIS Pro and Microsoft Excel to explore the local disease phenomena. TheCOVID-19 cases was most prevalent in the Petaling district, followed by Hulu Langat and Klang. The virus had the least impact in Sabak Bernam, Hulu Selangor, Kuala Selangor, Sepang, Kuala Langat, and Gombak. Three environmental factors of population density, the effects of urbanisation, and workplace cases were influential variables at the local clusters. These findings could help the local agencies to facilitate and control the spread mode of the virus in a spatial human environment.

Temporal effect of the spin-to-orbit conversion in tightly focused femtosecond optical fields.

Spin and orbital angular momenta are two of the most fundamental physical quantities that describe the complex dynamic behaviors of optical fields. A strong coupling between these two quantities leads to many intriguing spatial topological phenomena, where one remarkable example is the generation of a helicity-dependent optical vortex that converts spin to orbital degrees of freedom. The spin-to-orbit conversion occurs inherently in lots of optical processes and has attracted increasing attention due to its crucial applications in spin-orbit photonics. However, current researches in this area are mainly focused on the monochromatic optical fields whose temporal properties are naturally neglected. In this work, we demonstrate an intriguing temporal evolution of the spin-to-orbit conversion induced by tightly-focused femtosecond optical fields. The results indicate that the conversion in such a polychromatic focused field obviously depends on time. This temporal effect originates from the superposition of local fields at the focus with different frequencies and is sensitive to the settings of pulse width and central wavelength. This work can provide fundamental insights into the spin-orbit dynamics within ultrafast wave packets, and possesses the potential for applications in spin-controlled manipulations of light.

Resisting urban neoliberalism through social innovation

Centri sociali have been a common social, political, and spatial phenomenon in Italian cities since the 1970s. Since then, they emerged as active, youth-oriented places of left-wing and radical activism often operating at the margins of the urban fabric and in conflict with local institutions. In addition to political action, Centri Sociali play a social and cultural role in cities as spaces of leisure, social aggregation, and mutual support. This paper investigates how these groups locate themselves in an increasingly neoliberal urban environment by exploring their goals, the role they play in the wider communities, the issues they wish to address, and the strategies they mobilise. After presenting an overview of the concept and history of Italian Centri Sociali, the theoretical concept of urban neoliberalism is used to set the scene in which such groups are currently active and to explain the nature of the issues and challenges they aim to tackle. Further, the actions and strategies used by Centri Sociali are analysed through the lenses of Social Innovation Theory. This paper aims to understand how social innovation is used by Centri Sociali to create alternative urban spaces outside of neoliberal and capitalistic dynamics. It does so by using secondary data retrieved through literature review and through primary data collected via semi-structured interviews with 15 representatives from various Centri Sociali around Italy.

Towards strategy of geoinformation systems and technologies use for territory management

GeoInformation (GI) Systems (GIS) and GI Technologies (GIT, together GIST) have been used for almost half a century, since the creation of Canada's first GIS in the 60s of the last century, to solve territory management problems. Over the past years, GISTs have reached their maturity, but still continue to develop, covering ever wider areas of use. Even the science of geoinformatics has emerged, in which GIST is used mainly as a toolkit or technology. As an example, geoinformatics in the same Canada is called geomatics and is a technology and/or technological science. At the same time, the expansion of the field of GIST use poses to researchers the question of methods and methodology. They are followed by issues of methods and methodology of geoinformatics not only as a technology, but also as a science. Moreover, these issues become more complicated with the expansion of the field of use. In the information industry, together with the field of use, the term "domain" or "context" is used. Thus, modern GIST usage manipulate a large number of interrelated terms and concepts that are often not clearly defined. The work is devoted to the classification of the main ones, which are influenced by the strategy selected. Spatial models of territory are used in the work. They are used in the study of both territorial systems of reality and individual spatial entities and phenomena of reality. Among spatial models, the main attention is paid to information spatial models, the most famous of which are GeoInformation Systems (GIS). GIS are inseparable from GIS tools - GeoInformation Technologies (GIT). The main results of the article were obtained using the so-called method of Conceptual Frameworks (CoFr) of Spatial Information Systems (SpIS). The CoFr method is applied to a special class of GIS - Atlas Geo-Information Systems (AGIS) of large territories (LT). The AGIS class includes Electronic Atlases (EA), Atlas Information Systems (AtIS), Cartographic Information Systems (CIS) and, in fact, GIS, if we are talking about LT. AGIS-LT is a hierarchical echeloned SpIS, for which the main terms and concepts of the article are applicable. These are such terms and concepts as "strategy" and "methodology" of GIS usage. GIS, in turn, use GIT, which are also classified using CoFr SpIS.

ПОЛІТИКА ПРОСТОРУ, СОЦІАЛІСТИЧНИЙ УРБАНІЗМ І ТРАНСФОРМАЦІЇ: АНАЛІЗ ПЕРЕТВОРЕНЬ АДМІНІСТРАТИВНОГО ЦЕНТРУ КРИВОГО РОГУ

The urban spaces in Ukraine have been dynamically changed over the past decades, and the politics of space has also been transformed as a result of the changing imaginations on different types of the production of space – the socialist and the market one. During the transition period, the ideology of spatial development and politics that determine the goals, priorities and regulations in urban development have changed dramatically; as well as institutions and actors involved in the production of space. Thus, we observe today the process of not only physical transformations of urban areas, but also notions of them, priorities for their development, specific purposes, functions and regulation of their changes, spatial organization and its concepts, public involvement in the planning of urban areas. Post-socialist transition, in fact, denotes two completely different ways of producing the space – the socialist and the postsocialist. In this paper, we analyze the politics of space and spatial transformations, illustrating spatial restructurings through the changes of socio-political context - ideologies, institutions, actors and tools that shape it. We suggest that changes in the ways of the production of space and shifting from socialist to postsocialist urbanism are related specifically to the changes of these key dimensions. We consider the idea of Kryvyi Rih administrative center development through the several planning projects from the early 1930s (in relation to planning the socialist city in Kryvyi Rih) until the end of the 1980s (when project was partly implemented) in order to highlight the socialist urbanism as a spatial, social and ideological phenomenon. We analyze this urban space through the lens of socialism and post-socialist transition to illustrate how it transformed spatially, functionally and conceptually.
