Wolf, Garrett, e Nathan Mahaffey. "Designing Difference: Co-Production of Spaces of Potentiality". Urban Planning 1, n.º 1 (22 de março de 2016): 59–67. http://dx.doi.org/10.17645/up.v1i1.540.
Texto completo da fonteResumo:
Design and Planning professionals have long been influenced by the belief in physically and spatially deterministic power over people and the environment, a belief that their representations of space become space. As a result the goal of design often becomes “fixing” or directing behavior and culture instead of letting culture happen. This outlook often prevents designers from engaging critically with culture, through representational space and spatial practice, as a crucial, possibly the most crucial, aspect in the design process. Just as human cultures interact to constantly reproduce and co-produce hybrid cultures, the professional designer and those users and experiencers of design (at whatever scale) must interact to co-produce spaces and places of activity. Through a critique of the practice of placemaking, we highlight the need to differentiate between participation and co-production. Understanding participation as one element of the design process and the role of design at larger scales of co-productive processes can help designers have a better understanding of how spaces are produced, and the role of designers in the creation of spaces of potentiality. Agamben’s writing on<em> potentialities </em>and Lefebvre’s spatial triad offer a theoretical framework to investigate the ethical role of professional designers in society while taking a critical stance against the singular solutions of modernist urban transformation. Spaces of Potentiality are seen here as a designer’s simultaneous withdrawal from rational problem solving and deterministic solutions, and an engagement with open source strategies for the co-production of urban space.

Texto completo da fonteResumo:
This article develops the concept of proximity as socio-spatial distance by looking at the temporally and spatially condensed events of contemporary art exhibition openings. The article begins by examining some developments in proximity research, the limitations of theorizing the importance of proximity as mere physical nearness, arguing that potentiality renders proximity meaningful. After introducing the art event, we offer a three-pronged approach to proximity by showing the imperatives for being-there, the conditional indeterminacy of potentiality and the politics of proximity. In contrast to much recent research, it is argued that the significance of events is not reducible to evaluated outcomes. Two ethnographic vignettes show the imperatives, indeterminacies and politics in action. We conclude by showing how this conceptualization of proximity has analytic purchase beyond the empirical realm of contemporary art.

Texto completo da fonteResumo:
Exploring acoustic space, this article aims to supplement the practice of acoustic design by exposing other perspectives on sound’s relationship to space. Following Paul Carter’s notion of sonic ambiguity, the author contends that the idealized sonic image of acoustics eliminates the potentiality inherent to sound and listening as forces of relational intensity and differentiation. To draw out this tension, the article examines alternative forms of acoustics as appearing within the practice of sound art. Through eccentric and speculative design, sound art comes to demonstrate a vital addition to notions of acoustics; by creating heightened listening experiences that exceed the traditional concepts of fidelity, it cultivates forms of noise by integrating extreme volume and frequency, building fantastical architectures for their diffusion, and incorporating a dynamic understanding of psychoacoustics and perception. Through such elements, sound and space are brought together and deliver other forms of acoustical experience while hinting at potentialities for their application in environments outside the art situation. Works by such artists as Tao G. Vrhovec Sambolec and John Wynne provide a vibrant terrain for registering how sound comes to perform as spatial material.

Texto completo da fonteResumo:
Cet article interroge la relation de voisinage à partir de l’analyse de la figure du voisin dans la culture populaire (dictons, littérature, bande dessinée…) : figure péjorative, elle est globalement contredite par les discours, beaucoup plus positifs, recueillis lors d’entretiens semi-directifs sur le rapport spatial et social à l’environnement de l’individu. Il en ressort que la relation de voisinage, en plus de la spatialité, a deux dimensions majeures : la temporalité et la potentialité. Le voisin, parce qu’il demeure à proximité, est potentiellement nuisible ou utile. Par cette simple potentialité, la relation de voisinage fait que l’individu n’est pas exactement ce qu’il est, il est aussi le résultat de la proximité du voisin et de la relation de voisinage en tant que triplet spatialité/temporalité/potentialité. L’article vise ainsi à proposer une définition du concept de relation.

Texto completo da fonteResumo:
In this essay, I propose a new alliance between speculative realism and spatial theory. Whether interpreted as an avant-garde movement or simply as part of an evolution in human thought, the Speculative Turn in continental philosophy has an important link to spatial studies, a field replete with the study of imaginative and speculative texts. By applying various spatial theories to this unique philosophical movement, and thereby implicating ourselves within a space where we become linked in spatial being, we can endeavor to think the absolute from a place of ‘radical contingency’ and spatiality. This analysis, then, historicizes the movement via its academic and para-academic manifestations, as it asserts a mode of remembering that invokes the loss of cultural amnesia. Thus, it demonstrates that speculative realism is a good candidate for further critical inquiry, but also that spatial studies, with its interdisciplinary lens often informing and creating the cultural worlds we inhabit, is a good candidate for speculative realism to cast its exploratory vision.

AbstractFive non-potential parameters are calculated to investigate the temporal and spatial variations of vector magnetic field in active region 11158. An area that had evident changes of the azimuth of the vector magnetic field was found. The sunspot rotation may lead to an increase of the non-potentiality. Rapid and prominent increases are found in the variations of unsigned helicity.

Texto completo da fonteResumo:
Multiple speckle diffusing wave spectroscopy (MSDWS) can be applied to measure spatially heterogeneous mechanical behavior in soft solids, with high sensitivity to deformation and both spatial and temporal resolution. In this paper, we discuss the mathematical approach behind the quantification of the deformation rate from MSDWS data and provide guidelines for optimizing the selection of experimental parameters in measurements. After validating the method in extensional tests on an elastomer, we provide an example of the potentiality of MSDWS by measuring the spatial distribution of the deformation rate during shear debonding of adhesive tapes. We quantitatively characterize the deformation rate distribution related to shearing and peeling under loading. A highly heterogeneous deformation rate distribution is observed, and time-dependent measurements reveal an increase in deformation localization hundreds of seconds before full debonding. This behavior, previously predicted by theory and simulation, is demonstrated here experimentally for the first time.

Face au constat de l’inadaptation à la marche de certains espaces urbains apparaît un besoin de méthode d’évaluation et de représentation des pratiques pédestres. Pour y répondre, les dispositifs techniques dérivés des statistiques de la mobilité, de l’analyse spatiale de l’accessibilité et de la régulation des flux paraissent à la fois incomplets et biaisés par la recherche d’efficacité et de vitesse qui a marqué l’urbanisme de la fin du XX e siècle. Les revendications émergentes en faveur de villes « marchables » devraient pousser à exploiter davantage les potentialités de ces dispositifs de mesure.

Texto completo da fonteResumo:
Urban segregation is an inherent feature of cities and becomes a problem when excluding or hindering certain groups from accessing services, activities and spaces. In Brazil, segregation by social class is dominant in the structure of cities and public policies rarely address urban configuration as part of the segregation problem. This work addresses segregation with a shift in emphasis from traditional housing segregation to segregation as the restraint of socio-spatial interactions, thus including other facets of the phenomenon that have not yet been properly explored and seeking new spatially relevant metrics. This paper aims to present a methodology of segregation analysis based on configurational models and develop an empirical application in a Brazilian city. Representing the probabilities of interaction between different socio-economic groups in public spaces, a configurational model was used, addressing retail-residence spatial relationship. The attributes of population size, household income and number of retail establishments were considered. The results allowed identifying the probabilistic residence-retail trajectories for high and low income groups, providing a first measure of spatial segregation. The conclusions seek to highlight the importance of configurational approaches for segregation studies, as well as to show potentialities and limits of this methodology.

Texto completo da fonteResumo:
The drinking and irrigation water scarcity is a major global issue, particularly in arid and semi-arid zones. In rural areas, groundwater could be used as an alternative and additional water supply source in order to reduce human suffering in terms of water scarcity. In this context, the purpose of the present study is to facilitate groundwater potentiality mapping via spatial-modelling techniques, individual and ensemble machine-learning models. Random forest (RF), logistic regression (LR), decision tree (DT) and artificial neural networks (ANNs) are the main algorithms used in this study. The preparation of groundwater potentiality maps was assembled into 11 ensembles of models. Overall, about 374 groundwater springs was identified and inventoried in the mountain area. The spring inventory data was randomly divided into training (75%) and testing (25%) datasets. Twenty-four groundwater influencing factors (GIFs) were selected based on a multicollinearity test and the information gain calculation. The results of the groundwater potentiality mapping were validated using statistical measures and the receiver operating characteristic curve (ROC) method. Finally, a ranking of the 15 models was achieved with the prioritization rank method using the compound factor (CF) method. The ensembles of models are the most stable and suitable for groundwater potentiality mapping in mountainous aquifers compared to individual models based on success and prediction rate. The most efficient model using the area under the curve validation method is the RF-LR-DT-ANN ensemble of models. Moreover, the results of the prioritization rank indicate that the best models are the RF-DT and RF-LR-DT ensembles of models.

Emboldened by the economic crisis of 2007 to 2008, a growing rhizome of socially and politically engaged spatial practices have resorted to alternative modes of producing architecture that focus more on its societal aspirations. Aiming to uncover some of the potentialities of the projects that emerged from this growing rhizome to introduce other modes of making architecture while resisting dominant ones, this paper considers the Deleuzian-Guattarian concept of the “minor” to propose an alternative reading of such projects as “minor architectures,” that is, critical practices that resist the canon and act in the crevices of the mainstream. Using ethnographic research methods on two empirical cases, namely the Floating Berlin designed by Raumlabor and Agrocité Paris designed by Atelier d’Architecture Autogérée, the paper identifies “minor” spatial tactics of making architecture that go beyond the limit(ation)s of the practice: (1) resisting the architectural object as a static entity, (2) fostering collective expression, (3) exploring potentialities by reterritorializing interstitial spaces, and (4) creating haptic and affective experiences. The paper reflects on the concept of the minor as an operational tool that could help break away from dominant systems of architectural production.

Texto completo da fonteResumo:
In the field of groundwater engineering, a convolutional neural network (CNN) has become a great role to assess the spatial groundwater potentiality zones and land use/land cover changes based on remote sensing (RS) technology. CNN can be offering a great potential to extract complex spatial features with multiple high levels of generalization. However, geometric distortion and fuzzy entity boundaries as well as a huge data preparation severance may be the main constraint and affect the spatial potential of CNN application for land cover classification. This study aims to recognize the proficiency of deep learning algorithms, i.e., CNN, for spatial assessment of groundwater potential zones and land cover. Among the groundwater influencing factors, classification of land cover (agriculture, built-up, water bodies, forests, and bare land) has been reported by several researchers for different purposes and they approved the CNN capability for the prediction of spatial groundwater potentiality zones like very high, high, moderate, poor, and very poor areas. In this study, CNN is recommended as a very essential algorithm for the identification of groundwater potential zones and classification of land use/land cover change. CNN gives a better option for scholars regarding when the limited data sets are available for validation.

La production des formes en architecture est un acte dans lequel se construit le projet et se façonne l’espace. Elle est une action qui structure l’environnement humain. La conception architecturale est aussi une production spatiale de formes et exploration de potentialités de composition. Deux approches nous intéressent ici : formalisation du savoirfaire architectural et analyse des modes de composition en architecture. Il s’agit d’une part de comprendre la notion de composition, d’organisation et de configuration architecturale et d’autre part de décomposer, segmenter et caractériser morphologiquement un ensemble d’objets architecturaux (décors des fenêtres) en vue de mettre en évidence et d’expliquer les lois du système de formes qu’ils organisent. L’objectif est de développer des outils d’aide à la conception architecturale dans le cadre de la pédagogie du projet et de l’informatisation du savoir-faire architectural. La mise en place d’un environnement virtuel et d’un dispositif de matérialisation spatiale de formes apporte une aide opératoire dans la conception architecturale.

Texto completo da fonteResumo:
Water scarcity affects all continents, with approximately 1.2 billion people living in areas where water is physically lacking. This scarcity is more accentuated in countries with an arid climate, and its impact becomes more threatening when the economy depends mainly on it. The Kingdom of Morocco, with its agricultural vocation, is one of them, especially in its southern regions. Therefore, mapping areas with high groundwater potential based on available geospatial data allows for optimizing the choice of a future well in such areas. Geometric average and fractal models were used to assess and delineate potential groundwater areas in the Tissent basin, Southeast Morocco. Eight factors, including topography, geology, hydrology, and hydrogeology, influencing the distribution of water resources was used. The formation permeability factor presents the most significant impact among the others, although it is directly related to most of them. The areas located in the central and downstream part of the basin are characterized by a high water potentiality due to increased geological formations’ permeability near the drainage system, which constitutes a recharge zone, and a low slope allowing a prolonged water-formation contact time favoring a gradual infiltration of the water towards the deep aquifers. The groundwater potential map has been edited and validated by comparing it with data from 52 wells scattered throughout the basin. The favorable potential sectors cover 15.81% of the basin’s total area. The moderate ones account for 21.36% while the unfavorable areas cover 62.83%. These results aim to provide policymakers and managers with a guide map for groundwater research and reduce hydrogeological investigation costs.

Texto completo da fonteResumo:
The assessment of soil pollution is only one instance where geographic information systems (GIS) have shown to be an invaluable tool in environmental management and assessment. Globally, there is growing worry over soil pollution since it can have catastrophic repercussions on plant, animal, and human life. A more in-depth understanding of the scope and severity of contamination is made possible by GIS, which offers a flexible and all-encompassing method to studying and assessing soil pollution. With the aid of GIS technology, precise maps of soil contamination may be produced by combining data from numerous sources, such as remote sensing, aerial photography, and ground surveys. This information can then be evaluated using a variety of techniques, such as spatial analysis, to pinpoint polluted areas, possible sources of pollution, and the effects they are most likely to have on the environment and human health. By making it easier to identify sensitive regions that need additional research or remediation, GIS can also help with the analysis of the risk of pollutant movement and dispersion. Comparing GIS to conventional methods for assessing soil pollution has various benefits. First of all, it enables a more thorough and in-depth examination of the degree and breadth of contamination, enabling the identification of locations that need urgent care. Second, it makes it easier for different stakeholders, such as environmental agencies, researchers, and policymakers, to share data and information, enabling better decision-making. Thirdly, it makes it possible to monitor and control soil contamination more effectively, allowing for the early detection of potential issues and the implementation of suitable corrective actions. In general, GIS technology is a useful tool for assessing soil pollution since it offers a more thorough and knowledgeable approach to environmental management. It is a crucial tool for environmental experts engaged in the assessment and control of soil pollution due to its capacity to combine different data sources, perform spatial analysis, and promote information sharing.

Texto completo da fonteResumo:
Coastal areas are among the most endangered places in the world, due to their exposure to both marine and terrestrial hazards. Coastal areas host more than two-thirds of the world’s population, and will become increasingly affected by global changes, in particular, rising sea levels. Monitoring and protecting the coastlines have impelled scientists to develop adequate tools and methods to spatially monitor morpho-sedimentary coastal areas. This paper presents the capabilities of the aerial drone, as an “all-in-one” technology, to drive accurate morpho-sedimentary investigations in 1D, 2D and 2.5D at very high resolution. Our results show that drone-related fine-resolution, high accuracies and point density outperform the state-of-the-science manned airborne passive and active methods for shoreline position tracking, digital elevation model as well as point cloud creation. We further discuss the reduced costs per acquisition campaign, the increased spatial and temporal resolution, and demonstrate the potentialities to carry out diachronic and volumetric analyses, bringing new perspectives for coastal scientists and managers.

Wildlife assessments can provide crucial information regarding species richness, relative abundance and spatial, temporal, and ecological information on wildlife habitat associations. The assessment’s information can in turn be used for developing management policies including for establishing touristic zones. We investigated wildlife occurrences in the Chandragiri Hills, Kathmandu Nepal from 2015-2019 to provide baseline data to inform the potential sites for ecotourism. During the study period, we recorded 30 mammal species, 199 bird species, 34 herpetofauna species and 77 butterfly species. The area harbors three globally and six nationally threatened mammal species, two globally and seven nationally threatened with one endemic bird species, one globally and nationally threatened herpetofauna, and one nationally threatened butterfly species. We also explored four potential hiking routes for observing wildlife and providing scenic views of the Himalayan range and Kathmandu city. Therefore, we expect Chandragiri Hills can become one of the hot spot for tourists to observe both common and threatened wildlife species in Nepal.

Marine spatial planning has become the crucial issues for an archipelagic state such as Indonesia. The global market demand on marine economic species has been initiated the exploitation of the marine species which will become the hindrance in maintaining the sustainable marine biodiversity. Besides that, the degradation of marine species will also become the problem for traditional fishermen. Therefore, a model has to be employed to spatially manage the coastal waters as the alternative for fishermen activities during closed seasons, such as floating fish net culture. The aim of this study was to develop marine spatial planning model based on ecological approach in order to identify the potentiality of marine waters for marine culture such as floating fish net culture. The method for the model consisted of social assessment using the Delphi for developing the rule of marine planning for floating fish net culture and the spatial analysis technique for determining the model of marine spatial planning for floating fish net culture. The area of Kupang Bay waters, East Nusa Tenggara was used as the study area. The result indicated that the model can be used to sustainable marine spatial planning, especially for floating fish net culture. The model considered the aspects of potential area for marine culture, the management of zonation and transportation lanes, the conservation and protected area and the strategic area. Application in Kupang bay illustrated the aspect of technology input such as raceways since the majority of the area of Kupang Bay waters is classified as medium potential. Further research still needs to optimum the application of model to others marine area.

Texto completo da fonteResumo:
The fact that real-time autonomous vehicle (AV) traffic volume can be collected without a field detector by virtue of advanced global positioning system (GPS) and wireless communication technologies can render a promising solution to online monitoring of traffic volume in the upcoming AV era. To demonstrate this opportunity, this paper proposes a new method to monitor real-time motorway traffic volumes for road locations where no detector is installed using AV traffic volume. The modeling concept is based on the obvious fact that AV traffic volume is a direct portion of total traffic volume. The capabilities of the method are demonstrated through an experimental study using real-world GPS-enabled smartphone vehicle navigation data. The results show that online motorway traffic volume can be effectively monitored throughout the day with 5.69% average error at the 14.91% penetration rate of AVs during the daytime. Therefore, it is expected that AVs can at least be used as complementary means for the role of vehicle detectors in the near future due to the fact that the detection range of AVs is not spatially constrained.

Si la ville est faite pour tous ceux qui l'habitent elle est par contre le produit de quelques individus ou organismes spécifiques. Les nouveaux axes de développement, les nouvelles activités qui s'inscrivent sur le sol sont en effet le choix d'acteurs privilégiés qui non seulement participent aux décisions concernant l'organisation territoriale mais font prévaloir leurs vues. L'aménagement urbain est certes influencé par des facteurs nombreux et divers mais il offre un champ d'élection pour des conflits d'intérêt particulièrement aigus. Étudier les jeux en matière d'utilisation du sol n'est pas chose aisée car beaucoup d'actes en ce domaine, soit échappent à l'investigation, soit ne se sont pas révélés dans toute la complexité de leurs relations. Les résultats de ces jeux sont concrétisés dans le zonage, pouvoir réglementaire reconnu aux municipalités, qui fixe les choix en matière d'utilisation du sol. Mais préalablement au stade réglementaire, les préférences spatiales se sont exprimées, soit au niveau de la demande, soit au niveau de la consultation, soit au niveau de la décision, soit encore au niveau de la contestation. Or comme le souligne R. Babcock « of ail the areas of the law, zoning is the least susceptible to académie scrutin ». Évidemment le règlement de zonage ne fait qu'ouvrir des potentialités d'utilisation du sol. Celles-ci peuvent être conformes à la situation existante, proches de l'utilisation actuelle du sol, sensiblement ou totalement différentes. De plus, elles ne sont pas nécessairement suivies d'effets. Bref le potentiel ouvert par le zonage peut être très différent de l'utilisation actuelle et peut très bien ne pas être exploité. Mais dans ce dernier cas, on peut être assuré qu'à plus ou moins long terme, un amendement au zonage viendra modifier ce potentiel stérilisé pour le rendre effectivement réalisable à brève échéance. L'utilisation effective du sol doit normalement se conformer aux usages permis par le règlement de zonage ou ses amendements. Le potentiel ouvert par le zonage est donc une chose très importante pour les utilisateurs du sol qui ont donc intérêt à intervenir. Quels sont donc les différents acteurs qui participent aux choix concernant le potentiel d'utilisation du sol? On sait que ces choix sont laissés à la discrétion des conseillers municipaux, décideurs formels tenus seulement d'observer les principes généraux et règles juridiques applicables aux règlements. En effet les pouvoirs de zonage sont précisés dans divers textes juridiques qui souvent mêlent indistinctement zonage et construction3. Mais aucun critère ni objectif ne viennent limiter ces choix, qu'il s'agisse du découpage du territoire municipal en zones, de l'affectation des différentes zones ou des modalités plus précises d'occupation du sol. Cette absence de référence laisse donc le champ entièrement libre aux différents groupes d'intérêt qui s'affrontent et essaieront de faire prévaloir leurs objectifs divers. Bref les règles du jeu sont généralement informelles. Il faut les découvrir à travers les acteurs et leurs comportements. Ces acteurs peuvent intervenir, soit lors des règlements de base initiaux, soit lors de la refonte de règlements de base, soit enfin lors des amendements4. Mais ce sont surtout les amendements qui révèlent les acteurs : nous les avons donc privilégiés pour plusieurs raisons. En effet les travaux récents de D. Pilette ont abouti aux deux conclusions suivantes. D'abord un règlement de base intervient en moyenne tous les neuf ans. Ensuite les amendements transforment le règlement de base de façon substantielle. De plus le règlement de base initial n'est souvent que la consécration juridique d'un état de fait en matière d'utilisation du sol. Les autorités municipales attendent les projets pour modifier par amendements les usages permis et se conformer aux options souhaitées par les utilisateurs du sol. De plus les règlements de base subséquents ne constituent généralement qu'une simple refonte des règlements de base antérieurs modifiés moult fois par ces amendements. Nous avons par ailleurs signalé dans une autre étude l'importance quantitative des amendements ainsi que l'importance qualitative des transformations qu'ils entraînent dans le potentiel d'utilisation du sol. Or si une partie de ces amendements peut être inspirée par le Conseil municipal ou les services de la ville, une autre partie provient des requérants particuliers ou des promoteurs et constructeurs. De plus, alors que pour le règlement initial le Conseil a une autorité exclusive en matière d'adoption du règlement, pour les règlements et amendements subséquents il partage son autorité avec les électeurs propriétaires. Aux termes de l'article 426 (le) de la Loi des Cités et Villes, les électeurs propriétaires de la zone visée par le règlement et éventuellement des zones adjacentes peuvent exercer un pouvoir de contestation au cours d'une assemblée convoquée par le greffier. Si six d'entre eux ou la moitié des participants, au cas où leur nombre est inférieur à douze, demandent la tenue d'un référendum, le règlement est alors soumis à leur approbation lors d'un vote subséquent. Par contre tout règlement de base subséquent au règlement initial, s'il est également « passible » de contestation et d'approbation, est souvent l'œuvre d'un ou de quelques spécialistes. Comme pour le règlement de base initial, il s'agit d'un document global préparé par un urbaniste conseil, ou par le service spécialisé de la ville. Des consultations peuvent avoir lieu auprès de services techniques ou juridiques. Mais l'initiative de la refonte ou d'un nouveau règlement relève généralement de la municipalité. Enfin, il faut souligner que l'évaluation d'un document aussi global concernant tout le territoire et les usages appellerait une étude attentive et approfondie. Or, aussi bien les conseillers qui adoptent les règlements que les électeurs propriétaires qui peuvent les contester, n'ont la possibilité d'investir autant de temps que les technocrates pour évaluer toutes les implications d'un tel règlement. Les interventions sont donc plus rares. Par contre les amendements à incidence spatiale plus précise suscitent davantage d'intérêt et d'interventions diversifiées en fonction des zones concernées et des types d'usages. Ces différentes raisons, plus particulièrement la transformation substantielle des règlements de base, nous ont incités à reconnaître aux amendements une valeur stratégique dans la dynamique du zonage. Cette dynamique se manifeste par l'ampleur quantitative et qualitative des amendements dans le temps. Ceux-ci révèlent les différents acteurs impliqués dans les modifications apportées à la vocation du sol. En étudiant deux villes de la région montréalaise, nous avons tenté de reconstituer le processus de décision en matière de zonage, d'identifier les acteurs participants et d'étudier les différents types d'interventions sur le potentiel foncier.

Texto completo da fonteResumo:
Wastescapes are the result of unsustainable linear growth processes and their spatial consequences within the context of urban metabolic flows and related infrastructure. They represent the operational infrastructure for waste management and include Drosscapes, generating complex relations with the servicing and surrounding territory. In particular, the peri-urban areas are spatially affected by these processes. This often leads to ineffective use and/or abandonment because they are currently impossible to use, demanding impactful (and often expensive) regeneration and revalorization to make them usable again. Being part of the urban metabolic process, wastescapes are in a continuous state of dynamic equilibrium. They can be considered crucial areas from a metropolitan perspective because they have the potential to become innovative spatial contexts or resources in a Circular Economy (CE), which aims to overcome the crises of both resource scarcity and spatial fragmentation. However, common and shared definitions of wastescapes are still missing at the European policy level, as only classical categories of material waste are generally mentioned. Wastescapes can be considered as ‘potentiality contexts’ where developing, testing, and implementing Eco-Innovative Solutions (EIS) can be done. By doing so, wastescapes can help start transitions towards a CE. This can be achieved by using Peri-urban Living Labs (PULL), which have the potential to be the virtual and physical environments in which experimenting the collaborative co-creation process for developing EIS can be done. Doing so will allow for the improvement of waste management and for the revalorization of wastescapes in collaboration with all potential stakeholders.

Texto completo da fonteResumo:
Photoacoustic (PA) imaging is a novel, powerful diagnostic technique utilized in different research fields. In particular, during recent years it has found several applications in Cultural Heritage (CH) diagnostics. PA imaging can be realized in transmittance or epi-illumination (reflectance) modes, obtaining variable levels of contrast and spatial resolution. In this work, we confirmed the applicability of the PA technique as a powerful tool for the imaging of one of the most challenging artwork objects, namely fresco wall paints, to obtain precise stratigraphic profiles in different layered fresco samples. In this regard, we studied some multi-layered fragments of the vault of San Giuseppe Church in Cagliari (1870 AD) and some mock-ups realized specifically to test the potentiality of this technique. Due to complex structures of the frescoes, we used the Spatially Off-set Raman Spectroscopy (SORS) technique to provide complementary information. The experimental results were in agreement for both techniques, even for the three-layered complex structure, and were confirmed with Scanning Electron Microscopy (SEM) analysis of cross-sections. The combined use of these two techniques proved useful to investigate detailed hidden information on the fresco samples.

Les projets de réhabilitation des petites rivières urbaines se multiplient et s’inscrivent de plus en plus dans une approche multi-bénéfices visant notamment à répondre au besoin de nature exprimé par les citadins. Afin de fournir des outils pour appréhender les bénéfices sociaux de ces opérations, un diagnostic est proposé pour mesurer la connectivité sociale des petites rivières urbaines. S’appuyant sur la description de la configuration matérielle de deux cours d’eau franciliens et de leurs berges, il vise à qualifier les potentialités d’usage offertes par celles-ci. Il révèle une accessibilité non négligeable pour des cours d’eau non domaniaux tandis que les six types identifiés témoignent de la diversité des situations.

Multispiral computed tomography (MSCT) is a method of choice for evaluation of bone structure condition, as well as for visualization of growth zones, main and additional ossific nuclea of the articular elements. Besides, MSCT provides precise evaluation of spatial orientation of hip joint components, pattern of bone fragments displacement in traumatic injuries, localization of pathologic focus in bone pathology and degree of adjacent anatomic structures involvement. Contrast enhancement (double-contrast technique) markedly widens potentialities of this method as it enables to evaluate the condition of articular cartilage and soft tissue structures that is the most actual in young children.

It makes two points: one about the potential of thinking about place in (and for) EU law and a second about the idea that potentiality itself – a notion which alludes to what could be – could be thought of in spatial terms. The overarching suggestion is that these ways of thinking offer insights into the meaning of meaning in EU law.

Texto completo da fonteResumo:
The spatial turn within the humanities and need for data richness has led to the re-conceptualisation and exploration of maps as ‘deep maps.’ Building narratives of place is becoming increasingly contingent on data landscapes as opposed to the physical landscapes within which they are situated. To make the assumption that GIS can form the basis for deep maps is to privilege the spatial dimension (and spatial data) over all others. We have sought in our experimentation to take a more open, balanced approach as to how a deep map might be organised as a way of learning/reflecting on what elements a framework should contain. Our subject matter here necessitated attention to the challenges and potentialities of deep mapping ‘things deemed religious.’ We found spatial navigation to be useful for visualizing physical and metaphysical linkages, integrating the geographical portions of our spatial narrative as well as organizing thoughts off the map.

The successful launch of Luojia 1-01 complements the existing nighttime light data with a high spatial resolution of 130 m. This paper is the first study to assess the potential of using Luojia 1-01 nighttime light imagery for investigating artificial light pollution. Eight Luojia 1-01 images were selected to conduct geometric correction. Then, the ability of Luojia 1-01 to detect artificial light pollution was assessed from three aspects, including the comparison between Luojia 1-01 and the Suomi National Polar-Orbiting Partnership Visible Infrared Imaging Radiometer Suite (NPP-VIIRS), the source of artificial light pollution and the patterns of urban light pollution. Moreover, the advantages and limitations of Luojia 1-01 were discussed. The results showed the following: (1) Luojia 1-01 can detect a higher dynamic range and capture the finer spatial details of artificial nighttime light. (2) The averages of the artificial light brightness were different between various land use types. The brightness of the artificial light pollution of airports, streets, and commercial services is high, while dark areas include farmland and rivers. (3) The light pollution patterns of four cities decreased away from the urban core and the total light pollution is highly related to the economic development. Our findings confirm that Luojia 1-01 can be effectively used to investigate artificial light pollution. Some limitations of Luojia 1-01, including its spectral range, radiometric calibration and the effects of clouds and moonlight, should be researched in future studies.

Texto completo da fonteResumo:
Heritage and space establish reciprocal relations that have been studied for decades. On the one hand, heritage has been described as an inherently spatial phenomenon. On the other hand, places are defined according to the attributes that make up their identity, among which heritage is a fundamental instrument. On the basis of the idea that education plays an important role in the socialization process, transmitted by the inherited culture, to integrate each subject within the specific community, and the notion of scale as the closest to heritage, we defined as general objectives to determine the relationships between geographic scales, heritage perspective and the didactic potential granted to heritage, within the framework of the construction of collective identities, and to contrast the perspectives of students and teachers regarding the geographical scale, heritage and their didactic potential, deducing implications for educational practices. In order to answer to these objectives, we carried out a non-experimental quantitative research, with a relational-predictive objective. Specifically, we used a survey method, being the context the whole of the local scale (Fuente Álamo, Murcia, Spain) and acting as participants all students and teachers of Secondary Education (n = 459) linked to social sciences. They answered the Test on Didactic Potentiality of Heritage according to Scale (TDPHS), and its information was analysed through different procedures (Spearman’s correlations, descriptive statistics, Mann-Whitney U…), using the statistical programs SPSS. The results show, on the one hand, that the scalar perspective scores are generally low, heritage perspective is consistent with the consideration of the scales, and the perceived didactic potential in relation to heritage is related to the importance given to each of the scales; and, on the other hand, the contrast in the perspectives of students and teachers regarding the geographical scale, heritage and their didactic potential is minimal.

The quantity of water that can be extracted from a borehole is directly related to the groundwater potential of an area among other things. Boreholes drilled in areas of low groundwater potential have every tendency to fail. There have been reported cases of borehole failures in Okene Local Government Area of Kogi state. This study therefore aimed at analyzing the potentiality of groundwater and the spatial relationship between borehole yield and groundwater potential zones in the area. Various data which include Sentinel 2 satellite image, Digital Elevation Model, geological map, rainfall data and borehole yield data were analyzed to produce various zones of groundwater potential, and validated using existing borehole yields and the relationship was tested using Pearson correlation. The result of this study reveals that the low potential zone covers 33.2%; moderate potential zone occupies 44.9% which cuts across the whole of Okene LGA and the high potential zone covers 21.9% mainly found around the western part of the area. The Pearson moment correlation analysis result revealed a strong positive correlation (R) value of 0.919. The correlation value shows that there is a strong positive relationship between the existing borehole yields in the study area and the groundwater potentiality map produced from the analysis. The study concluded that there is a strong positive relationship between the existing borehole yields and the groundwater potential zones in Okene Local Government Area.

Currently, climate change poses a global threat, which may compromise the sustainability of agriculture, forestry and other land surface systems. In a changing world scenario, the economic importance of Remote Sensing (RS) to monitor forests and agricultural resources is imperative to the development of agroforestry systems. Traditional RS technologies encompass satellite and manned aircraft platforms. These platforms are continuously improving in terms of spatial, spectral, and temporal resolutions. The high spatial and temporal resolutions, flexibility and lower operational costs make Unmanned Aerial Vehicles (UAVs) a good alternative to traditional RS platforms. In the management process of forests resources, UAVs are one of the most suitable options to consider, mainly due to: (1) low operational costs and high-intensity data collection; (2) its capacity to host a wide range of sensors that could be adapted to be task-oriented; (3) its ability to plan data acquisition campaigns, avoiding inadequate weather conditions and providing data availability on-demand; and (4) the possibility to be used in real-time operations. This review aims to present the most significant UAV applications in forestry, identifying the appropriate sensors to be used in each situation as well as the data processing techniques commonly implemented.

Texto completo da fonteResumo:
Abstract This work offers a novel methodological framework to address the problem of generating data-driven earthquake shaking fields at different vibration periods, which are key to support decision making and civil protection planning. We propose to analyse the entire profiles of spectral accelerations and project their information content to unsampled locations in the system, based on the theory of Object Oriented Spatial Statistics. The proposed methodology combines a non-ergodic ground motion model with a fully functional model for the residual term, the latter consisting of (i) the spatially-varying systematic effects due to source, site and path, and (ii) the remaining aleatory error. The proposed methodology allows to generate multiple shaking scenarios conditioned on the data, jointly and consistently for all the vibration periods, overcoming the intrinsic limitations of existing multivariate approaches to the problem. The approach is tested on a vast dataset of ground motion records collected in the study-area of the Po Plain (Northern Italy), for which a region-specific fully non-ergodic GMM was previously calibrated. Our validation tests demonstrate the potentiality of the approach, which is capable to effectively simulate spectral acceleration profiles, while keeping the ability to capture the main physical features of ground motion patterns in the region.

Texto completo da fonteResumo:
This work explores the advantages and drawbacks of the application of Digital Image Correlation (DIC) to Sentinel-2 Multi Spectral Instrument (MSI) data in conjunction with continuous Global Navigation Satellite System (GNSS) monitoring. The goal is to retrieve a spatially distributed and long-term time-series of slope movements in large-scale moderately rapid landslides. The short revisit time of Sentinel-2 satellites (5 days since March 2017 and 10 days before) increases the availability of cloud and snow free satellite acquisitions of the area of interest, which is a prerequisite for the extrapolation of slope movement time-series using DIC techniques. Despite the Sentinel-2 limited spatial resolution, the derived long time-series can be integrated with—and validated by—continuous GNSS monitoring data. This allows to effectively monitor landslide movements that are too fast for the application of interferometric approaches. In this study, we used the Normalized Cross Correlation (NCC) digital image correlation technique by 51 Sentinel-2 MSI scenes (band 4 with 10 m spatial resolution), acquired between 19 February 2016 and 16 July 2019, to derive the slope movement time-series of the Ca’ Lita earthslide-earthflow in the northern Apennines (Italy). During the period considered, the landslide experienced two to three months-long phases of moderately rapid velocity (around 10 m/month) and, in between, prolonged periods of slow movements (approx. 10 cm/month). NCC results have been integrated with, and are compared to, time series from three continuous GNSS devices located in different geomorphic zones of the landslide. On this basis, the errors and limitations associated to NCC time series are analysed and discussed together with their advantages and potentialities for assessing the spatial distribution and monitoring slope movements during moderately rapid reactivation events.

Difference is not an epiphenomenon of socio-spatial relations, but a genuine worldmaking driving-force, provided that it is the handling of difference that paves the way to specific interactions that end up shaping society and, ultimately, space. There exists not merely ‘a world of difference’ but a world because, and out of, differences. This article offers a neo-Hegelian analysis of the spatial basis of politico-economic and ethnic-social differences, making use of the striking example of anti-difference violence suffered by indigenous peoples under the hegemony of financial-rentier capitalism. There are two main pillars of socio-spatial difference, ethnicity and class, which co-determine each other and eventually result in hybrid, ethnoclass differences held by all humans and according to their specific and general circumstances. The socio-spatial trajectory of the Guarani-Kaiowa indigenous nation, in the center of Brazil, is emblematic of the dialectical basis of ethnoclass differences, and also of the political potentiality of difference.

Electrospinning is gaining increasing interest in the biomedical field as an eco-friendly and economic technique for production of random and oriented polymeric fibers. The aim of this review was to give an overview of electrospinning potentialities in the production of fibers for biomedical applications with a focus on the possibility to combine biomechanical and topographical stimuli. In fact, selection of the polymer and the eventual surface modification of the fibers allow selection of the proper chemical/biological signal to be administered to the cells. Moreover, a proper design of fiber orientation, dimension, and topography can give the opportunity to drive cell growth also from a spatial standpoint. At this purpose, the review contains a first introduction on potentialities of electrospinning for the obtainment of random and oriented fibers both with synthetic and natural polymers. The biological phenomena which can be guided and promoted by fibers composition and topography are in depth investigated and discussed in the second section of the paper. Finally, the recent strategies developed in the scientific community for the realization of electrospun fibers and for their surface modification for biomedical application are presented and discussed in the last section.

The areas surrounding Iraqi international airports generally suffer from a lack of interest in their planning in a manner compatible with the airport with the absence of integrated planning between the airport and the city. From here, the search problem appears. It is represented by a lack of interest in the integration of urban planning and airport planning and the lack of a clear policy to deal with the areas surrounding international airports. A desire to achieve the research aims to introduce compatible uses in the vicinity of airports and review the planning and global directions for dealing with the areas surrounding the airports within urban areas. In contrast, the second aspect of the research aims to assess the uses of the land surrounding the airports and determine their compatibility with the planning directions of these areas. The research studied the areas surrounding Baghdad International Airport and conducted a comprehensive survey of land uses within a distance of (4) km from the airport runway center. Then it conducted an analysis using geographical information systems(GIS) and studied the survey results, and assumed that the current uses of the areas surrounding international airports do not reflect the optimal use of these areas and, therefore, not exploiting the current capabilities and development opportunities provided by the airport for the surrounding areas. The research hypothesis is tested through the use of (GIS )and displaying the results of the field survey of land uses within the study area.
Furthermore, the methodology of comparative spatial analysis was done by monitoring the current situation through (GIS) and analyzing the result and comparing it with international standards to achieve results that contribute to attaining physical development. The first part of the research presents an introduction to international airports that are one of the most significant urban nodes in the city. The surrounding areas have many features that require regulation and coordination. The presence of incompatible uses in the vicinity of the airport leads to the loss of the advantages provided by the airport and the occurrence of adverse effects on the surrounding areas. Part two introduced compatible uses in the vicinity of airports. Part Three analyzed the case study of the areas surrounding Baghdad Airport. Then the results of the field survey showed that there are incompatible uses and the absence of compatible uses, and this case requires the identification of many planning procedures and benefiting from global trends in planning these areas.

Texto completo da fonteResumo:
The content of the general geographical concept of geospatial positionality (geopositionality) is revealed in the context of the relation of a single object / place with geospace, as well as the function of geoplace. Conceptual and terminological analysis of the concept is carried out in formal and semantic aspects. Using an explanatory dictionary of the modern Ukrainian language highlighted the meaning of placementtokens (position, location, positioning, neighborhood, proximity / remoteness) and the possibility of their use in geographical texts. Based on the study of scientific sources, object-centric, functional and integrated logical models of the concept of geopositionalityareelaborated. The directions of evolution of object-centric interpretation of the concept are revealed: clarification of the token of relation (sum of relation, set of relation, combination of relation, integral of relation; spatial, geographical, territorial, geospatial relations; spatial aspects of relation); determining the geopositionality of objects of ever smaller spatial coverage; the dominance of the ‘external’ approach to content disclosure; multiscale; potentiality. The functional model of the concept of geopositionality is created through the sequential deployment of the features, relations, potential, functions of geoplace. The semantic triangle of the concept of geopositionality of the object in the unity of its aspectsmeaning and conceptual content is developed. The main attributes of geopositionality (uniqueness / specificity, distance, potentiality / probability, hierarchy / multiscale, dynamism / historicity / variability) are highlighted, and their effect on different logical models are shown. The main directions of development of the concept of geopositionality are defined: nomination of features of geospatial relations of linear, areal, network geoobjects; nomination of dynamism of geopositionality of objects; positioning in relation to geospatial processes; mutual enrichment of semantically closest geopositional concepts; correct application of content and quantitative research methods for mathematical formalization and interpretation of geospatial relations of position and functioning. The classical, non-classical and modern stages in the development of the concepts of geospatial positionality are distinguished.
