Six‐Axis Ground Motion Measurements of Caldera Collapse at Kīlauea Volcano, Hawai'i—More Data, More Puzzles?

Near‐field recordings of large earthquakes and volcano‐induced events using traditional seismological instrumentation often suffer from unaccounted effects of local tilt and saturation of signals. Recent hardware advances have led to the development of the blueSeis‐3A, a very broadband, highly sensitive rotational motion sensor. We installed this sensor in close proximity to permanently deployed classical instrumentation (i.e., translational seismometer, accelerometer, and tiltmeter) at the Hawaiian Volcano Observatory (USGS). There, we were able to record three ~Mw 5 earthquakes associated with large collapse events during the later phase of the 2018 Kīlauea summit eruption. Located less than 2 km from the origins of these sources, the combined six‐axis translational and rotational measurements revealed clear static rotations around all three coordinate axes. With these six component recordings, we have been able to reconstruct the complete time history of ground motion of a fixed point during an earthquake for the first time

Experimental Analysis of the Thermal Performance of Wood Fiber Insulating Panels

During the last decades, attention to energy and environmental problems has significantly grown, along with the development of international and national policies addressing sustainability issues. In the construction sector, one of the most widespread energy efficiency strategies consists of thermal insulation of buildings thanks to external insulating panels. Among these, wood fiber is an insulating material characterized by a natural, eco-sustainable and biodegradable structure, coming from the recycling of waste wood from sawmills. The present study aimed to characterize small test building insulated with wood fiber panels from the thermal point of view, comparing the results with those of an identical, non-insulated reference test building. The experimental campaign highlighted several advantages and an excellent thermal performance provided by the eco-sustainable solution of wood fiber insulating panels: Lower values of the thermal transmittance (-57%), thus ensuring greater stability of the internal air temperature and better values in terms of attenuation (-60% in summer and -74 % in winter) and phase shift (+2 h in summer and +2.28 h in winter) compared to those obtained from the reference building. The material is also equipped with an Environmental Performance Declaration (EPD) that certifies its environmental benefits

'Alive after five' : constructing the neoliberal night in Newcastle upon Tyne.

The development of the ‘night-time economy’ in the UK through the 1990s has been associated with neoliberal urban governance. Academics have, however, begun to question the use and the scope of the concept ‘neoliberalism’. In this paper, I identify two common approaches to studying neoliberalism, one exploring neoliberalism as a series of policy networks, the other exploring neoliberalism as the governance of subjectivities. I argue that to understand the urban night, we need to explore both these senses of ‘neoliberalism’. As a case study, I take the ‘Alive After Five’ project, organised by the Business Improvement District in Newcastle-upon-Tyne, which sought to extend shopping hours in order to encourage more people to use the city at night. Drawing from Actor-Network-Theory, I explore the planning, the translation, and the practice of this new project. In doing so, I explore the on-going nature and influence of neoliberal policy on the urban night in the UK

Exploring relationships between soundscape and lightscape perception: A case study around the Colosseum and Fori Imperiali in Rome

Recently, there has been a growing interest to implement a holistic approach to study perception in urban settings with historic value, in which environmental factors such as acoustics and lighting play an important role. However, little research has addressed sound and light in combination. In this exploratory field study, a soundscape and lightscape protocol was implemented to gather both objective and subjective data. In all, 46 people joined a group walk around the historical sites of Colosseum and Fori Imperiali in Rome. Participants assessed the soundscape and lightscape quality via questionnaire at four locations, immediately before and after the sunset in April 2021. Acoustic parameters (A-weighted equivalent sound level, loudness, sharpness, roughness) and lighting parameters (luminance, colour rendering index and correlated colour temperature) were measured at each location while participants filled in the questionnaire. While there was little variation in the acoustic parameters measured before and after the sunset walks, changes were observed in perceptual data about the soundscape. These outcomes reveal a potential effect of lighting conditions on soundscape perception

Ultra-infra: Becoming Skin

This demonstration showcases outcomes from a program of research that seeks to expand the practice of painting through the exploitation of new digital technologies. Through virtual reality and digital painting processes, this research interrogates the nature of materiality by considering the hidden realities of human skin. The demonstration is in the form of a VR-based artwork delivered on a Windows Mixed Reality headset

Cinematic and aesthetic cartographies of subjective mutation

This article exmaines the use of cinema as a mapping of subjective mutation in the work of Deleuze, Gauttari and Berardi. Drawing on Deleuze's distinciton between the reduction of the art-work to the symptom and the idea of art as symptomatology, the article focuses on Berardi's use of cinematic examples, posing the quesiton in each case of to what extent they function as symptomatologies or mere symptoms of cultural and subjective mutations in examples ranging from Bergman's Persona to Van Sant's Elephant to finish on speculations about Fincher's The Social Network as a cirtical engagement with subjective mutation in the 21st Century
