Jones -- The history of St. Catherines Island after 1684 / Roger S. Durham and David Hurst Thomas -- Appendix: Notes on ethnohistorical resources and methodology / Grant D. Jones."This volume, the first in a series, considers the natural and cultural background to anthropological research being conducted on St. Catherines Island, Georgia. The island is one of a complex series of barrier islands, of various orgins. The extant vegetation is an interesting mixture of natural succession, periodically disrupted by recent historical processes. Archaeologists have worked on St. Catherines Island discontinuously since 1896, when C.B. Moore conducted excavations in several prehistoric burial mounds. The University of Georgia then conducted a program of burial mound and midden excavations in 1969-1970, and the American Museum of Natural History began intensive archaeological investigations on St. Catherines Island in 1974. The ethnohistory of the Guale Indians is discussed in detail, suggesting that they were essentially a riverine people with strong internal trade contacts. Guale political organization was that of the classic Creek chiefdom. Each chiefdom maintained two principal towns, and may have been organized according to dual political organization. This interpretation contrasts sharply with the traditional view of the Guale, who are often characterized as isolated, scattered, shifting cultivators. The volume concludes with a historical outline of St. Catherines Island from the early Spanish mission period up to present times"--P. 159
Reduced order models for control of fluids using the Eigensystem Realization Algorithm
In feedback flow control, one of the challenges is to develop mathematical
models that describe the fluid physics relevant to the task at hand, while
neglecting irrelevant details of the flow in order to remain computationally
tractable. A number of techniques are presently used to develop such
reduced-order models, such as proper orthogonal decomposition (POD), and
approximate snapshot-based balanced truncation, also known as balanced POD.
Each method has its strengths and weaknesses: for instance, POD models can
behave unpredictably and perform poorly, but they can be computed directly from
experimental data; approximate balanced truncation often produces vastly
superior models to POD, but requires data from adjoint simulations, and thus
cannot be applied to experimental data.
In this paper, we show that using the Eigensystem Realization Algorithm (ERA)
\citep{JuPa-85}, one can theoretically obtain exactly the same reduced order
models as by balanced POD. Moreover, the models can be obtained directly from
experimental data, without the use of adjoint information. The algorithm can
also substantially improve computational efficiency when forming reduced-order
models from simulation data. If adjoint information is available, then balanced
POD has some advantages over ERA: for instance, it produces modes that are
useful for multiple purposes, and the method has been generalized to unstable
systems. We also present a modified ERA procedure that produces modes without
adjoint information, but for this procedure, the resulting models are not
balanced, and do not perform as well in examples. We present a detailed
comparison of the methods, and illustrate them on an example of the flow past
an inclined flat plate at a low Reynolds number.Comment: 22 pages, 7 figure
South End Mound complex
46 p. : ill., maps ; 26 cm.Includes bibliographical references (p. 44-46)."This volume presents results of archaeological excavations of two prehistoric burial mounds on St. Catherines Island, Georgia. South End Mound I is an Irene period mortuary site, initially excavated by C.B. Moore during the winter of 1896-1897. Although Moore adequately described his investigations in a subsequent publication, he retained only six complete ceramic vessels for later analysis. These vessels have been reexamined and are discussed here. None of the skeletal materials excavated by Moore, to our knowledge, was saved for later analysis. Field crews from the American Museum of Natural History recently reexcavated parts of this site, finding evidence that at least some of the primary human burials previously exposed by Moore remain intact beneath the backdirt of South End Mound I. Further investigation might be fruitful. South End Mound II, a previously unexplored mortuary site, was discovered not far from Moore's excavations. This St. Catherines/Savannah period burial mound, extensively excavated by the American Museum of Natural History, had a central pit containing two cremations and a mass grave containing at least 15 individuals. Grave goods included a perforated copper sheet, worked galena, a river otter mandible, and a polished stone pendant. Prehistoric copper has rarely been reported from archaeological contexts from this area and, to our knowledge, this is the first occurrence of galena in coastal Georgia. Mound construction methods resemble those employed at Johns and Marys mounds, two roughly contemporary mortuary sites on St. Catherines Island"--P. 4
Empirical Legal Studies Before 1940: A Bibliographic Essay
The modern empirical legal studies movement has well-known antecedents in the law and society and law and economics traditions of the latter half of the 20th century. Less well known is the body of empirical research on legal phenomena from the period prior to World War II. This paper is an extensive bibliographic essay that surveys the English language empirical legal research from approximately 1940 and earlier. The essay is arranged around the themes in the research: criminal justice, civil justice (general studies of civil litigation, auto accident litigation and compensation, divorce, small claims, jurisdiction and procedure, civil juries), debt and bankruptcy, banking, appellate courts, legal needs, legal profession (including legal education), and judicial staffing and selection. Accompanying the essay is an extensive bibliography of research articles, books, and reports
