Mud Brick Metaphysics and the Preservation of Earthen Ruins

In the conservation of built heritage, earthen ruins rank as one of, if not the most, intractable of problems to be confronted. Lacking the very architectural devices originally in place to combat and control weathering, earthen ruins face rapid deterioration without constant remedial and preventive conservation. Often it is the enormous mass of many ancient earthen ruins that explain their persistence; however, even these will collapse over time from differential erosion, or eventually stabilize as formless lumps. The impossible demands of simultaneously preserving architectural form and fabric (materiality) challenge the archaeologist and conservation professional who attempt to manage both for temporary and permanent display.     

A NEOCLASSICAL MODEL OF REGIONAL GROWTH IN INDONESIA

In this paper a neoclassical model of regional growth is specified, estimated, and applied to the provinces of Indonesia. While parametric estimates indicate that factors of production respond as expected to neoclassical incentives, the attractiveness of growing regions for capital and labor inputs leads to instability and divergence among regions when the model is solved dynamically. A simulation of government intervention via a policy of encouraging capital growth in lagging regions demonstrates the potential of reversing such effects and encouraging regional convergence.     

Archaeological Survey of the Ex-USS <Emphasis Type="Italic">Bugara</Emphasis> (SS/AGSS331)

In August 2017, a multidisciplinary team conducted the first archaeological survey of the deep water (242 m) wreck of the ex-USS Bugara (SS/AGSS331) using the remotely operated vehicles Argus and Hercules. The survey provided 8 h of direct observation with video and still camera documentation of the wreck, which previously had been identified by sonar and a brief ROV survey of portions of the hull in 2001. The 2017 assessment added considerably to an understanding of changes to Bugara after it sank while under tow in 1971. Bugara, a World War II-era submarine, served at the end of that conflict and through the Cold War. The submarine reflects a series of modifications to “modernize” it within the context of the Cold War. The examination of the wreck, along with additional archival research, offers more details not only on the probable cause of the sinking but also on subsequent site formation processes. The characterization of the wreck resulted in a reassessment of the site as more than an obsolete vessel accidentally lost when relegated to target practice. The archival record, now declassified, shows that Bugara’s loss also reflects its ultimate use, within the context of the Cold War, as a target for the Mark 48 torpedo, a newly developed “sub and ship killing” weapon designed in the late 1960s and tested through 1971 to take out Soviet deep-diving nuclear submarines and high-performance surface ships.
