Mast-Step Coins among the Romans

The archaeological evidence of more than a dozen ancient shipwrecks indicates that the tradition of placing a coin inside the mast-step of a ship's hold probably originated with the Romans. The mast-step coin phenomenon, which persisted through the Middle Ages and continues in various forms today, has often been characterized according to the modern concept of 'luck'. The custom was, however, not one of an exclusively maritime nature; rather, it was ultimately derived from a long-standing religious tradition that can be traced back to the consecration of the earliest Greek temples.

School Choice and Educational Stratification

Recent growth in the number of school choice programs across the country has ignited debate on the stratifying effects of these programs. In the context of interdistrict open enrollment, this paper analyzes—both theoretically and empirically—how choice programs affect stratification levels through the mechanisms of (i) the relative characteristics of program participants and nonparticipants and (ii) the schooling choices of different groups of program participants. The theoretical analysis uses Monte Carlo simulation techniques to analyze a hypothetical world where interdistrict choice is available to students in three school districts that are allowed to vary in student composition, the type of students who take advantage of the interdistrict choice program, and schooling choices of students who open enroll. The results of these simulations provide an understanding of the conditions under which an interdistrict open enrollment program leads to increases, decreases, or no changes in stratification levels. The empirical analysis uses data from the universe of students attending Colorado public schools in 2009–10 to examine how the state's interdistrict choice program affects stratification levels. It also analyzes the factors responsible for any increases or decreases in stratification and finds both participation patterns and differences in schooling decisions across groups to play important roles. The paper concludes with a discussion of its implications for research and policy.     

Impact of Modification on Ground Motion Characteristics and Geotechnical Seismic Analyses for a California Site

The impact of different modification techniques on ground motion characteristics and results of seismic geotechnical analyses is investigated for a site in California. Twenty-eight motions were selected and scaled and also modified using both time domain (TD) and frequency domain (FD) techniques. PGV and PGD of the TD-modified motions are found to be larger than their FD-modified counterparts, but slightly less than the scaled ground motion characteristics. Cyclic stress ratios and amplification factors are similar for all sets of motions. Newmark-type slope displacements caused by the scaled and modified ground motions are similar (within 25%) for a variety of sliding masses.     

The Underwater Recovery of Monumental Marble Column Drums from an Ancient Shipwreck at Kızılburun,Turkey

In the first century B.C., a stone carrier sank off the Aegean coast of Turkey at K?z?lburun transporting all the elements of a monumental marble column, including a single Doric capital and eight drums. The 60-tonne cargo lay at a depth of 45–48 m and was excavated in its entirety by the Institute of Nautical Archaeology at Texas A&M University between 2005 and 2011. Ongoing research has shown that the Doric column pieces in the K?z?lburun cargo originated in the marble quarries on Proconnesus Island in the Sea of Marmara and were very likely heading for the Temple of Apollo at Claros when the ship sank just 50 km short of its destination. The complete recovery of the ship’s cargo posed a unique set of methodological challenges involving lifting the multi-tonne marble drums without disturbing the delicate waterlogged wooden hull remains preserved beneath. This report summarizes the solutions developed over five seasons in order to rig, hoist, move, and ultimately raise to the surface eight large ancient marble column drums (as well as all the other marble artifacts in the cargo) from a depth of almost 50 m under water.     

‘Making Change’ in the memorial landscape to the Dakota–US War of 1862: remembrance,healing and justice through affective participation in the Dakota Commemorative March (DCM)

The Dakota–US War of 1862 led to the removal and exile of Dakota people from their ancestral homeland. Integral to this process was the forced march of 1,700 women, children and elders from the Lower Sioux Agency to Fort Snelling, Minnesota. Despite the siting of numerous memorials related to the war and its aftermath, few mark the forced march and its legacies. Since 2002, however, the seven-day Dakota Commemorative March (DCM) has been held biennially to remember and honour Dakota ancestors on the original forced march. Following a brief overview of extant place-based memorials at sites along its path, we draw on documentary sources to explore the significance of the DCM as a distinctive Dakota intervention in the commemorative landscape. Through a process we call ‘affective participation’ – an intense bodily, emotive and transformative engagement in an event – participants on the DCM not only seek to remember but also strive towards healing and justice in the present and the future. Our hope is to expand the focus of current geographical work on discrete site-based memorials to consider the social- and cultural-geographical significance of alternative (particularly Native) forms and scales of commemoration.     

Festschrift

By working largely unaware of the huge literature in anthropology and certain other social sciences on ethnogenesis, Western cultural/historical and ethnic geographers remain aside from the mainstream in this inquiry and in fact do not address the topic as often as one might expect. Anthropologists have dominated ethnogenetic research for decades in North America. We further marginalize our work on ethnogenesis by ignoring completely the work of the Russian Leo Gumilev, a fellow geographer who devoted his career to the study of this subject. I le remains virtually unknown in the West in spite of English translations of a number of his works. This neglect of the works of anthropologists and Gumilev leads Western geographers to deal with ethnogenesis infrequently and somewhat naively. Hie authors suggest that by becoming familiar with these valuable sources and by applying existing, well-developed cultural geographical themes and concepts, such as homeland, diffusion, landscape, preadaptation, and incremental change, Western cultural geographers can more abundantly and significantly join the debate on ethnogenesis, building upon Gumilev's foundation and offering a humanistic, particularistic, and holistic alternative perspective largely absent in anthropological and other nongeographical studies.
