This article introduces the recent sound works of Heidi Fast, a Finnish voice and performance artist. Fast’s creative practice operates between art and philosophy, and articulates several ‘zones of becoming’: what Fast designates as ‘the clinical’, ‘the virtual’ and ‘vocal thought-material’. Using a methodology of routing, the article shows how these zones emerge as aesthetic, ethical and political concerns within Fast’s work. Since 2005, Fast’s sound works have variously taken shape as miniature concerts, social sculptures, imaginary soundscapes and environmental music performances. Drawing upon the writings of theorists who have helped shape her practice, this article argues that Fast uses sound and voice to propose an ‘actualising philosophy’. This philosophy actualises virtualities (unrealised potentials), affecting transformative shifts through tiny mutations in perceptions and behaviours.

It has long been accepted that thermal and moisture regimes within stonework exert a major influence upon patterns of salt movement and, subsequently, the type and severity of salt-induced decay. For example, it is suggested that slow drying is more likely to bring dissolved salts to the surface, whereas rapid drying could result in the retention of some salt at or near the frequent wetting depth. In reality however, patterns of heating, cooling and surface wetting regimes that drive them – are complex and inconsistent responses to a wide range of environmental controls. As a first step to understanding the complexity of these relationships, this paper reports a series of experiments within a climatic cabinet designed to replicate the effects of short-term temperature fluctuations on the surface and sub-surface temperature regimes of a porous Jurassic limestone, and how they are influenced by surface wetting, ambient temperature and surface airflow. Preliminary results confirm the significance of very steep temperature/stress gradients within the outer centimetre or less of exposed stone under short-duration cycles of heating and cooling. This is important because this is the zone in which many stone decay processes, particularly salt weathering, operate, these processes invariably respond to temperature and moisture fluctuations, and short-term interruptions to insolation could, for example,
trigger these fluctuations on numerous occasions over a day. The data also indicate that there are complex patterns of temperature reversal with depth that are influenced in their intensity and location by surface wetting and moisture penetration, airflow across the surface and ambient air temperature. The presence of multiple temperature reversals and their variation over the course of heating and cooling phases belies previous assumtions of smooth, exponential increases and decreases in subsurface temperatures in response, for example to diurnal patterns of heating and cooling

This article introduces examples of recent sound art in Belfast, a city that has undergone radical transformation over the past decade and is home to a burgeoning community of sound artists. The text investigates the ways in which sonic art can redraw boundaries in a city historically marked by myriad political, socioeconomic,
religious and sectarian divisions. The article focuses on sound works that reimagine a “post-conflict” Belfast. These include site-specific sound installations in urban and public spaces, soundwalks, sculptures, locative and online works, and experimental
sonic performances that draw upon traditional Irish song and music.

The Natural Stone Database for Northern Ireland was constructed to address the paucity of information available to stone conservation practitioners within the region. Almost 2000 listed buildings and monuments were surveyed over three years to produce an interactive GIS database. This contained information on stone sources, together with details of stone condition and decay processes. This paper uses elements of this GIS to investigate stone decay patterns across Northern Ireland. The results demonstrate that as the level of stone decay increases, so does the proportion of buildings with sandstone as the primary stone type. It appears that a
higher open porosity level combined with Northern Ireland’s wetter climate and maritime location leads to rapid wetting and drying cycles within sandstones. This is coupled with the ingress and crystallisation of marine and other salts within stone pores leading to considerably
higher rates of decay than for any other stone type.

The Settlement at Dhaskalio is the first volume in the series The Sanctuary on Keros: Excavations at Dhaskalio and Dhaskalio Kavos, 2006-2008, edited by Colin Renfrew, Olga Philaniotou, Neil Brodie, Giorgos Gavalas and Michael Boyd. Here the findings are presented from the well-stratified settlement of Dhaskalio, today an islet near the Cycladic island of Keros, Greece. A series of radiocarbon dates situates the duration of the settlement from around 2750 to 2300 BC. The volume begins with a discussion of the geological setting of Keros and of sea-level change, concluding that Dhaskalio was in the third millennium BC linked to Keros by a narrow causeway. The excavation and finds (excluding the pottery, discussed in later volumes) are fully documented, with consideration of stratigraphy, geomorphology, organic remains, and the evidence for metallurgy. It is concluded that there was a small permanent population of around 20, increased periodically by up to 400 visitors who would have participated in the rituals of deposition occurring at the Sanctuary at Kavos, situated opposite, on Keros itself, for which the detailed evidence (including abundant fragmented pottery, marble vessels and sculptures) will be presented in Volumes II and III
