The Sand Creek Massacre and the History of Greater Reconstruction in the American West

In the traditional U.S. historical narrative, the Civil War & Reconstruction era is a North vs. South story. Nevertheless, the era of western expansion, a central theme throughout the nineteenth century, has no contingent place within this traditional narrative. Meanwhile, the history of the American West and its diverse peoples appears in many textbooks as an unrelated albeit contemporaneous narrative. Separated by geographical regions, historians often do not examine these concurrent histories. However, many of these historical events and actors were interconnected. As I am interested in understanding the Reconstruction era’s national impact, I intend to explore how Reconstruction policies were enacted in the 1860s and 70s trans-Mississippi West, building which builds on the historical contributions of Historian Elliot West in “Greater Reconstruction,” which aims to reimagine a more national ideal of Reconstruction, not confined to the Southern states. Moreover, this era includes western Native peoples\u27 post-Civil War reform era history. This project aims to uncover the history of the Reconstruction of Native peoples by concentrating on the Southern Arapaho and Cheyenne of the Colorado plains territory. Elliott West’s “Greater Reconstruction” concept specifically connects mid-nineteenth-century race-making and nation-state-building political projects in the American South and West. For this project, I plan to center the 1864 Sand Creek massacre that took place in the southeastern Colorado Territory as a marking point in the Civil War in the West and Greater Reconstruction. This massacre involved the brutal murder and mutilation of an estimated 200 Cheyenne and Arapaho people by the U.S. Army. By contextualizing this massacre in terms of other Civil War-era Indian “wars,” I will be able to examine the federal government’s decision to investigate the attack on the Native people, which was not only a common occurrence but widely supported among military personnel. I will significantly rely on Congressional testimony and investigation reports (39th Congress, 2nd Session, U.S. Senate, Reports of Committees, No. 156.), along with Bureau of Indian Affairs records (Record Group 75.19.10). These sources will help me determine why this particular Native massacre received so much federal scrutiny. I also intend to put the Sand Creek investigation in a historical conversation with the federal government’s attempts to reconstruct the Southern Arapaho and Cheyenne through new treaty provisions (primarily in the Medicine Lodge Treaty of 1867) that forced them into reservation life in Native Territory. Rather than portraying these developments as contradictory, I hope to connect them by identifying their shared Greater Reconstruction-era political motivations as 19th-century Republicans attempted to build a politically and culturally unified nation. More broadly, I hope to shed light on an overlooked aspect of Greater Reconstruction and its complicated and often negative impact on the Arapaho people. In so doing, this project contributes to the growing inclusion of marginalized voices and perspectives in the history of Reconstruction, which is still primarily dominated by prominent American military and political figures. Finally, this project will take steps to clarify the meaning and legacy of this critical era of political reform and nation-state building concerning American society today

Changes in shell durability of common marine taxa through the Phanerozoic: evidence for biological rather than taphonomic drivers.

Abstract.-Phanerozoic trends in shell and life habit traits linked to postmortem durability were evaluated for the most common fossil brachiopod, gastropod, and bivalve genera in order to test for changes in taphonomic bias. Using the Paleobiology Database, we tabulated occurrence frequencies of genera for 48 intervals of ,11 Myr duration. The most frequently occurring genera, cumulatively representing 40% of occurrences in each time bin, were scored for intrinsic durability on the basis of shell size, reinforcement (ribs, folds, and spines), life habit, and mineralogy. Shell durability is positively correlated with the number of genera in a time bin, but durability traits exhibit different temporal patterns across higher taxa, with notable offsets in the timing of changes in these traits. We find no evidence for temporal decreases in durability that would indicate taphonomic bias at the Phanerozoic scale among commonly occurring genera. Also, all three groups show a remarkable stability in mean shell size through the Phanerozoic, an unlikely pattern if strong sizefiltering taphonomic megabiases were affecting the fossil record of shelly faunas. Moreover, small shell sizes are attained in the early Paleozoic in brachiopods and in the latest Paleozoic in gastropods but are steady in bivalves; unreinforced shells are common to all groups across the entire Phanerozoic; organophosphatic and aragonitic shells dominate only the oldest and youngest time bins; and microstructures having high organic content are most common in the oldest time bins. In most cases, the timing of changes in durability-related traits is inconsistent with a late Mesozoic Marine Revolution. The post-Paleozoic increase in mean gastropod reinforcement occurs in the early Triassic, suggesting either an earlier appearance and expansion of durophagous predators or other drivers. Increases in shell durability hypothesized to be the result of increased predation in the late Mesozoic are not evident in the common genera examined here. Infaunal life habit does increase in the late Mesozoic, but it does not become more common than levels already attained during the Paleozoic, and only among bivalves does the elevated late Mesozoic level persist through the Holocene. These temporal patterns suggest control on the occurrence of durability-related traits by individual evolutionary histories rather than taphonomic megabiases. Our findings do not mean taphonomic biases are absent from the fossil record, but rather that their effects apparently have had little net effect on the relative occurrence of shell traits generally thought to confer higher preservation potential over long time scales

Creative Thinking and Modelling for the Decision Support in Water Management

This paper reviews the state of art in knowledge and preferences elicitation techniques. The purpose of the study was to evaluate various cognitive mapping techniques in order to conclude with the identification of the optimal technique for the NetSyMod methodology. Network Analysis Creative System Modelling (NetSyMod) methodology has been designed for the improvement of decision support systems (DSS) with respect to the environmental problems. In the paper the difference is made between experts and stakeholders knowledge and preference elicitation methods. The suggested technique is very similar to the Nominal Group Techniques (NGT) with the external representation of the analysed problem by means of the Hodgson Hexagons. The evolving methodology is undergoing tests within several EU-funded projects such as: ITAES, IISIM, NostrumDSS

Global climate analysis of growth rings in woods, and its implications for deep time paleoclimate studies

We outline a plausible evolutionary sequence that led from prokaryotes to the origin of the first nucleated cell. The nucleus is postulated to evolve after the archaebacterium and eubacterium merged to form the symbiotic ancestor of amitochondriate protists. Descendants of these amitochondriate cells (archaeprotists) today thrive in organic-rich anoxic habitats where they are amenable to study. Eukaryosis, the origin of nucleated cells, occurred by the middle Proterozoic Eon prior to the deposition in sediments of well-preserved microfossils such as Vandalosphaeridium and the spiny spheres in the Doushantou cherts of China
