The Ereğli E Shipwreck,Turkey: an early Hellenistic merchant ship in the Black Sea

A shipwreck from the early 3rd century BC was discovered in the Black Sea's suboxic depths off Ere?li, Turkey, during the 2011 E/V Nautilus expedition. Remote investigation revealed the trawl‐damaged remains of a merchant ship carrying multiple amphora types associated with Aegean and Pontic production areas. Also discovered were elements of the ship's hull that show evidence of both pegged mortise‐and‐tenon and laced construction. The wreck provides crucial archaeological evidence for both maritime connectivity and ship‐construction methods during a period of political and economic transition.     

Investments in Scientific Research: Examining the Funding Threshold Effects on Scientific Collaboration and Variation by Academic Discipline

This paper seeks to examine how federal financial support of academic scientists shapes their collaborative behavior. More specifically, it investigates two questions: (i) are there threshold sizes of federal grants that have effects on collaboration? and (ii) do the threshold sizes differ by discipline? To test and model these questions, this paper uses data collected in a 2004–2005 survey by the Research Valuing Mapping Project (a project based at Georgia Tech and led by Barry Bozeman) of 2,086 academically based research scientists and engineers. The analysis in this paper reaffirms the positive relationship between federal funding and collaboration seen in previous works, but the findings suggest that there is in fact a threshold effect—as the positive relationship has a diminishing influence. The findings of this paper are more limited with respect to how academic disciplines’ threshold levels differ. The results indicate a difference in the threshold levels between disciplines for three of the eight models.

Terra incognita: terrestrial LiDAR documentation of Mound A at Kolomoki (9ER1)

ABSTRACT

The manifest representation of space and place is essential to good archaeology. Our ability to document and relate these concepts, projected into the past and reflected in the present, has increased tremendously with the expansion and availability of technology. We present recent efforts to further document a well-known place in the cultural landscape: the Kolomoki site in southwestern Georgia, occupied primarily during the Middle and Late Woodland periods. Specifically, we summarize older investigations of Mound A, then present the results of recent terrestrial LiDAR documentation. Our work substantiates the claim that Mound A was the largest Woodland-period mound in Eastern North America in terms of overall volume.     

Using AMOEBA to Create a Spatial Weights Matrix and Identify Spatial Clusters

The creation of a spatial weights matrix by a procedure called AMOEBA, A Multidirectional Optimum Ecotope-Based Algorithm , is dependent on the use of a local spatial autocorrelation statistic. The result is (1) a vector that identifies those spatial units that are related and unrelated to contiguous spatial units and (2) a matrix of weights whose values are a function of the relationship of the ith spatial unit with all other nearby spatial units for which there is a spatial association. In addition, the AMOEBA procedure aids in the demarcation of clusters, called ecotopes, of related spatial units. Experimentation reveals that AMOEBA is an effective tool for the identification of clusters. A comparison with a scan statistic procedure (SaTScan) gives evidence of the value of AMOEBA. Total fertility rates in enumeration districts in Amman, Jordan, are used to show a real-world example of the use of AMOEBA for the construction of a spatial weights matrix and for the identification of clusters. Again, comparisons reveal the effectiveness of the AMOEBA procedure.
