The longitudinal study of land-use at Acconia: Placing the fieldwork of the survey archaeologist in time

Abstract

This article presents the results of the longitudinal study of land-use conducted at Acconia in southern Italy between 1980 and 2007. This is the first of several articles planned on the landscape dynamics that took place there over a span of 27 years. Here we trace the sequence of the steps in the work of the Acconia Survey and the evolution in our thinking that led to the start of the longitudinal study, outline the fieldwork conducted at Acconia in 2007 and 2008, and present the changes in land-use that took place between the first mapping in 1980 and the fourth one in 2007. The final section considers some of the implications of what we have observed for the development of method and theory in survey archaeology. One of the main conclusions to emerge from the longitudinal study is that the work of the survey archaeologist should be seen as situated in time.     

Facts and Myths about Research on Public Policy Implementation: Out-of-Fashion, Allegedly Dead, But Still Very Much Alive and Relevant

Despite several decades of research on public policy implementation we know surprisingly little, not only about cumulative research results, but also about several other key aspects of this research field. This article tries to amend these deficiencies by presenting the results of a comprehensive literature survey. Its main purpose is to challenge, revise, and supplement some conventional wisdom about implementation research. A second motivation is to lay the foundation for and initiate a much needed synthesis of empirical research results. The main results are: The overall volume of publications on policy implementation has not stagnated or declined dramatically since the mid 1980s as is commonly asserted. On the contrary, it has continued to grow exponentially through the 1990s and into the twenty-first century. Even more surprising is that a large number of publications are located outside the core fields. Hence, the literature is substantially larger and more multidisciplinary than most commentators realize. Doctoral dissertations are the most ignored, but probably the richest, largest, and best source of empirical research results. Tracing the origin as well as the location of the disciplinary and geographical cradle of implementation studies must also be readjusted significantly. The ethnocentric bias of this research field toward the Western hemisphere has been, and still is, strong and some policy sectors are given much more attention than others. Although positive in many ways, the predominant multidisciplinary character of implementation research still poses some serious problems with respect to theory development. Thus, I discuss whether a resurgence of interest in policy implementation among policy scholars may already be occurring. Finally, I suggest that the time is long overdue for efforts to synthesize research results in a more rigorous scientific manner than has hitherto been done.

Satellite imagery and archaeology: the example of CORONA in the Altai Mountains

Satellite imagery, and specifically CORONA, is now of common use in archaeology. CORONA, as it produces two images of the same spot (afterward and forward), allows for stereoscopic view and is a perfect tool for the production of maps, especially in remote areas, where maps are not reliable of even absent.     

Integrating shallow geophysical survey: archaeological investigations at Totógal in the Sierra de los Tuxtlas,Veracruz, México

The Postclassic site of Totógal in the western Tuxtla Mountains of Veracruz, Mexico contains rare examples of stone architectural features in the southern Gulf Lowlands. Today, the partial remains of one such structure are highly visible; however, the amount of wall fall, looters' pit destruction and over-growth masks the extent and form of the feature. Local histories ascribe these ruins to early Colonial construction periods, however Postclassic Aztec-style artifacts recovered near this architecture question the occupational sequence of the site and its constructions. To better examine the extent of construction, as well as the occupation associated with them, we conducted a program of shovel testing, topographic mapping, electromagnetic induction survey and excavation. We discuss our findings in this paper and demonstrate the utility of geophysical surveys as complementary field strategies in the Tuxtla Mountains and other volcanic regions.     

The spiral that vanished: the application of non-contact recording techniques to an elusive rock art motif at Castlerigg stone circle in Cumbria

This article describes the recording of stone 11 of the Castlerigg stone circle in Cumbria through two different non-contact techniques: laser scanning and ground-based remote sensing. Despite the unproblematic recording of modern graffiti, neither technique was able to document the spiral photographed and rubbed in 1995. It is concluded that the spiral was most probably painted and has since faded away due to natural events. The discovery and loss of the spiral motif in Castlerigg is seen as a cautionary tale. In particular, it seems to suggest that it is time to take advantage of the novel technologies based on the digitisation of 3D surfaces with millimetre and submillimetre accuracy such as laser scanning and ground-based remote sensing. They offer many advantages to the recording of prehistoric carvings. In addition to avoiding direct contact with the rock surface eliminating the preservation concerns raised by other techniques, both produce high quality images (laser scanning offering a greater potential for this, but at higher cost) having a much higher level of objectivity, and precision and accuracy far beyond those of traditional recording methods such as wax rubbings and scale drawings.

Integrated near-surface geophysical survey of the Cathedral of Mallorca

This paper describes an integrated near-surface geophysical study carried out in order to obtain high-resolution images of the shallow subsurface under and around the Cathedral of Mallorca. The study was a part of a global project focused on determining the state of the building structure and on evaluating the Cathedral's dynamical behaviour (natural frequencies and vibration modes). Ground-penetrating radar (GPR) and the capacitively coupled resistivity method were used to obtain 2D images of the shallow subsurface. Refraction microtremor array measurements (ReMi) were also used to characterize the rock and soil properties and several invasive boreholes provided detailed and exact information on the stratigraphy. The information from the geophysical data was used to determine a final model of the ground, with indications of the most likely vulnerable zones.     

The design of effective and efficient trial trenching strategies for discovering archaeological sites

This paper reports a study on the effectivity and efficiency of trial trenching strategies for site discovery within the context of Dutch archaeological heritage management. It discusses the principles of site discovery by means of trial trenching, and suggests the optimal strategies for trial trenching survey, based on the results of simulations. Effective and efficient strategies for discovering different groups of archaeological sites are given, according to their presumed size, shape and feature density. The recommended strategies will be included in the Quality Norm for Dutch archaeology.     

Magnetic detection of ship ballast deposits and anchorage sites in King Herod's Roman harbour,Caesarea Maritima,Israel

Ballast stone deposits are a common feature of sediments in ancient harbour basins but are often overlooked as a potential source of archaeological information. Recent geophysical investigations at Caesarea Maritima in Israel have discovered a thick, laterally extensive ballast layer in the area seaward of the 1st c. BC Roman harbour. The ballast deposits were identified by low-relief mounds on the seabed with elevated magnetic intensities. Jet probing and excavation of magnetic anomalies at several locations revealed a 20–60 cm thick rubble layer containing large quantities of Late Roman and Byzantine pottery, local sedimentary boulders (kurkar sandstone, limestone cobbles) and foreign igneous and metamorphic boulders (granite, schist, volcanics; ca. 50%). The foreign boulders and pottery identify the rubble layer as ballast and ships refuse jettisoned by merchant ships outside the harbour. The strong magnetic contrast between the ballast deposits and the natural seabed sediments is attributed to the high magnetic susceptibility (>10⁻³ SI) of crystalline boulders and pottery materials within the ballast rubble.
