Understanding visual engagement with urban street edges along non-pedestrianised and pedestrianised streets using mobile eye-tracking

Existing knowledge of street edge experience has often been constructed using methods that offer a limited opportunity to gain empirical insight from the first-hand perspective of pedestrians. In order to address this, mobile eye-tracking glasses were used during the current investigation to provide a detailed understanding of pedestrian visual engagement with street edges along both non-pedestrianised and pedestrianised urban streets. Through this, the current study advances empirical knowledge of street edge experience from a perspective that has previously been challenging to capture and quantify. The findings demonstrate that people visually engage with street edge ground floors more than their upper floors, that visual engagement is distributed more towards the street edge on the walked side of non-pedestrianised streets than the opposite side, and that visual engagement with street edges of pedestrianised streets is balanced across both sides. The study findings also highlight how the everyday activities of pedestrians and different streets being walked often influence the amount of visual engagement within these street edge areas. These insights provide a new understanding that develops existing knowledge of pedestrian street edge experience. Significantly, they also provide an empirical foundation from which to examine how design intervention can become more considerate of peoples’ routine use of and experiential engagement with street edges along non-pedestrianised and pedestrianised urban streets

A conceptual framework for urban commoning in shared residential landscapes in the UK

This paper uses ideas central to the notion of urban commoning to develop a conceptual framework that can be used to inform the design and management of shared residential landscapes in the UK. Shared residential landscapes provide an important backdrop for everyday social interaction, chance encounters and mutual understanding. A recent revival of the commons concept within the urban context has brought forth new ideas for the design and long-term management of shared urban resources through participation and collective action. However, despite the potential benefits of urban commons for improved quality of urban living, there remains a disconnect between commons and spatial theory, obstructing effective application. Of particular significance are the role of physical space and the design professions in enabling or hindering the collective practice of urban commoning. To address this, this paper reviews the evolution of the commons, the implications for applying them to the urban context, and spatial theories in developing a conceptual framework for their application within the UK residential sector. Finally, the example of cohousing in the UK is drawn upon as an illustration of the urban commons framework. The framework creates a foundation for further research on the design and long-term management of shared residential landscapes as urban commons to benefit the everyday social lives of residential communities

Visual engagement with urban street edges: insights using mobile eye-tracking

This study provides empirical insight into the extent to which pedestrians visually engage with urban street edges and how social and spatial factors impact such engagement. This was achieved using mobile eye-tracking. The gaze distribution of 24 study participants was systematically recorded as they carried out everyday tasks on differing streets. The findings demonstrated that street edges are the most visually engaged component of streets; that street edge visual engagement is impacted by everyday social tasks as well as the spatial and physical materiality of edges on differing streets; and that street edges, which attract a lot of visual engagement while undertaking optional tasks, also attract greater amounts of visual engagement while undertaking necessary tasks. These findings offer new insight into urban street edge engagement from the direct perspective of street inhabitants and in doing so provide greater understanding of how street edges are experienced

Public squares in European city centres

During the latter part of the twentieth century, while a small number of exemplar city centre squares continued to be attractive places, the vast majority acquired either an image of empty spaces or an unattractive picture as traffic islands. This was emphasised by the decline of traditional community activities and the perception of comfort generated by internalising external space; coupled with a commodifying of cities in which they were merely viewed as commercial and retail opportunities. Communities need public spaces as places for assembly. They are the physical manifestation that each community is coherent and vibrant. Increasingly, it is being recognised that identity and place have enormous roles in reinforcing society. The re-introduction of public squares is part of reversing the erosion of the public sector and the public realm, and reclaiming city centres from private interests for the benefit of communities. Criteria for comfortable external spaces have been researched, and these recognise the differences between Northern and Southern Europe. The most recent advances are in the simulation of city centre design; which includes geometry, uses, pedestrian movement and environmental conditions. There is confidence to be gained from visualisation of how squares will look, feel and be used; and will make a real contribution to sustainable urban design

Validating DICOM Content in a Remote Storage Model

Verifying the integrity of DICOM files transmitted between separate archives (eg, storage service providers, network attached storage, or storage area networks) is of critical importance. The software application described in this article retrieves a specified number of DICOM studies from two different DICOM storage applications; the primary picture archiving and communication system (PACS) and an off-site long-term archive. The system includes a query/retrieve (Q/R) module, storage service class provider (SCP), a DICOM comparison module, and a graphical user interface. The system checks the two studies for DICOM 3.0 compliance and then verifies that the DICOM data elements and pixel data are identical. Discrepancies in the two data sets are recorded with the data elements (tag number, value representation, value length, and value field) and pixel data (pixel value and pixel location) in question. The system can be operated automatically, in batch mode, and manually to meet a wide variety of use cases. We ran this program on a 15% statistical sample of 50,000 studies (7500 studies examined). We found 2 pixel data mismatches (resolved on retransmission) and 831 header element mismatches. We subsequently ran the program against a smaller batch of 1000 studies, identifying no pixel data mismatches and 958 header element mismatches. Although we did not find significant issues in our limited study, given other incidents that we have experienced when moving images between systems, we conclude that it is vital to maintain an ongoing, automatic, systematic validation of DICOM transfers so as to be proactive in preventing possibly catastrophic data loss

Vitalit\ue0 della cultura classica nel dialogo con il contemporaneo (a proposito della mostra di F. Vezzoli \u201cMuseo Museion\u201d)

Il contributo \ue8 incentrato sul tema dell'attualizzazione dell'arte e della cultura classica realizzata nella mostra di Francesco Vezzoli intitolata "Museo Museion", esposta presso il Museo d'arte moderna e contemporanea di Bolzano. Essa offre l'esempio di una originale rilettura e di un vitale dialogo tra passato e presente, particolarmente adatto ad incuriosire e coinvolgere le nuove generazioni, nel confronto - talvolta bonariamente ironico - fra armonia classica ed emotivit\ue0 moderna
