Archaeological Survey of the Ex-USS <Emphasis Type="Italic">Independence</Emphasis> (CVL22)

In August 2016, a multidisciplinary team conducted the first archaeological survey of the deep-water (829 m) wreck of the ex-USS Independence (CVL22) using the remotely operated vehicles Argus and Hercules. The survey provided 34 h of direct observation with video and still camera documentation of the wreck, which the previous year had been initially identified with a limited three-dimensional sonar survey of the site. The 2016 assessment added considerably to an understanding of changes to Independence after its use as a target vessel for the 1946 atomic bomb tests at Bikini Atoll, as a radiological laboratory, training facility, and finally as a receptacle for “nuclear waste” prior to its scuttling off California in January 1951. The location and detailed examination of the wreck, along with additional archival research, offers a more nuanced definition of the carrier’s role within the context of the Cold War between the USSR, its adversaries and the race to establish nuclear supremacy, as well as site formation processes and ongoing biological colonization of the wreck site. As well, no evidence of residual radiological contamination was noted during the mission.     

USS <Emphasis Type="Italic">Independence’s</Emphasis> Aircraft

Submerged aircraft are a newly emerging area of study in underwater archaeology. In August 2016, a multidisciplinary team conducted the first archaeological survey of the deep water (829 m) wreck of the ex-USS Independence (CVL22), a WWII era light carrier scuttled off San Francisco after its use as an atomic bomb test target and subsequently as a floating radiological laboratory and training facility. Using the remotely operated vehicles Argus and Hercules, the expedition documented and studied Independence including assessment of a sonar target thought to be an aircraft resting inside the sunken carrier’s forward elevator pit. The survey confirmed the presence of a plane, but previous assumptions as to the type and identity of this aircraft, based on archival records, proved erroneous. As well, the remains of a second, and possibly a third, aircraft were also encountered during the 2016 survey. These artifacts, through their context, both as naval warplanes on an aircraft carrier, and as test articles for seaborne nuclear weapons development, more precisely fit within the parameters of maritime archaeology. They join other archaeological evidence at the Independence site that helps define its significance within the context of World War II and the Cold War.     

Reinforcement of the 18th Century Buttresses of Maniace Castle: Design and Execution

ABSTRACT

Maniace Castle, built on Ortygia island in Siracusa (Italy) in the first half of the 13th century and hosting a magnificent hypostyle hall (the Salone), a square area covered by 25 cross vaults supported by columns, was severely damaged by the 1693 earthquake and the explosion of the ammunition dump in 1704. The buttresses, built immediately afterward to counteract the thrust of the 10 surviving vaults, did not guarantee adequate seismic safety so that a metal scaffolding was installed in 2001 to prevent an overturning mechanism. This article discusses the design and execution of an external pre-stressing steel system to increase existing buttress strength and the seismic capacity of the Salone, starting with historical and constructional analyses and dealing with both analytical and technical aspects. The monitoring system installed to detect structural response during and after the working execution is shown, along with some of the data acquired so far.     

Stories about building history told by wooden elements – case studies from Eastern Austria

The intention of this article is to show the benefit of an interdisciplinary approach within the various disciplines of building research (architectural archeology, art history, archive research, dendrochronology, etc.).

The exact determination of the age of historical timber is undoubtedly the most important contribution of dendrochronology to building research. The significance of dendrochronological dates is discussed in detail—problems of reuse, repair, drying time, and differences between felling and building dates are demonstrated. Several case studies in Eastern Austria showed a difference of two to four years between felling and building.

To answer questions of where the timber came from, dendroprovenancing was introduced to Eastern Austria. First results showed that it will be possible to differentiate the origin of timber between Eastern Austria and regions where rafts started towards Vienna, via the river Danube. The results showed that it is important to combine building archaeology and archival analyses with the dendrochronological results.     

History and Characteristics of Construction Techniques Used in Traditional Timber Ottoman Houses

The aim of this article is to make a comprehensive review of the traditional timber house constructions in Turkey, which constitutes the majority of the existing Ottoman architectural legacy. After a short historical background focused on the Ottoman territory, the first section explores regional differences in the housing tradition, developed according to local features and defined by architectural features, material characteristics, and availability of materials. Derived from these regional differences, in the second section diversity in traditional timber construction systems in Turkey is described with special emphasis on the Ottoman h?m?? system. In this part, besides the discussion of the h?m?? technique which spread over Ottoman lands from the Balkans to Syria, the timber masonry and frame systems of the Eastern Black Sea Region and Thrace are presented in detail with visual support.     

Geophysical investigations of WWII air-raid shelters in the UK

Just before WWII, the British government prepared for an aerial onslaught that was predicted to raze cities and cause mass casualties. By 1938, the Air Raid Precautions Act officially stated that population protection would be through dispersal, meaning evacuation and small-scale protection, local authority responsibility often devolving to householders. Archaeological records of remaining air-raid shelters are relatively rare and under threat. This paper reports on geophysical surveys on three sites in Stoke-on-Trent and London. Results found three intact Stanton shelters in Stoke-on-Trent, located by GPR, electrical resistivity, magnetometry, gravity and electromagnetic methods. In London, partially demolished shelters and an intact, mass public shelter were both detected by EM and GPR methods, with subsequent intrusive investigations confirming results. Study outcomes show hitherto-neglected wartime shelters are in varied condition, with geophysical surveys able to detect, characterise and assess them, helping bring WWII British history into the wider scientific community and public domain.     

Siberia and neighboring regions in the Last Glacial Maximum: did people occupy northern Eurasia at that time?

An updated analysis of Paleolithic sites in Siberia and the Urals ¹⁴C-dated to the coldest phase of the Last Glacial Maximum (LGM), with its timespan currently determined as ca. 23,000–19,000 BP (ca. 27,300–22,900 cal BP), is presented. It is demonstrated that people continuously occupied the southern and central parts of Siberia and the Russian Far East (up to 58° N latitude), and perhaps sporadically settled regions located even further north, up to 70° N, throughout the LGM. This is in accord with our previous data, but is now based on a larger dataset, and also on a paleoecological analysis of the major pre-LGM archaeological sites in Siberia and the Urals north of 58° N. It is clear that Paleolithic people in northern Eurasia were able to cope with the treeless tundra environment well in advance of the LGM, at least at ca. 34,000–26,000 BP (ca. 38,500–30,000 cal BP). Therefore, a high degree of adaptation to cold conditions allowed people to survive in Siberia during the LGM.     

Leibniz’s Kehre: From Ultradeterminism to the Philosophy of Freedom

Abstract

This article examines the rift in Leibniz’s conception of determinism after being rebuffed by the Parisian theologian Antoine Arnauld in their correspondence of 1686. As, in addition, his study of surds infracted his confidence in the “complete concept,” Leibniz embarked on a new, dynamic doctrine of substance or “law of the series.” In the literature, this strategy has been widely (mis)understood as “tweaking” the system to allow some self-assertion of free will. But as this article will show, it amounts to a revolutionary conception that culminates in the unmasking of determinism as an insupportable, indeed incoherent doctrine. As all forms of determinism are profoundly entangled with human self-perception, the Leibnizian Kehre invites us to a new engagement with human freedom and autonomy and the disentanglement from a philosophical position for which neither a metaphysical nor an empirical proof can be given.     

Danto and the Pale of Aesthetics

Arthur Danto’s Transfiguration of the Commonplace is a new theory of art, seeking to catch the flavour and essence of its contemporary phenomenology. It is obliged, however, to pit itself in toto against aesthetic philosophy, leaning on the derivatives from deuteropraxis and institutional definition while committing itself to a concept of arthood extracted from exoteric ideas, which are held to comprise the artworks’ individuation and identity. This paper examines the principal notions in support of his contentions and contrasts them to the chief principles of aesthetic philosophy. In this juxtaposition, it transpires that conviction eludes Danto, as his suppression of aesthetic criteria yields unsuspected aporias from a disconjugate amalgam of inherence, ontology, epistemology and concept integration. Thus the leap from “mere real things” to the plateau of arthood is never accomplished, as it falters at the step where a perceiving subject has a stake in, and the power of authorisation, of this conception of art.
