Book Summary: World at War: Understanding Conflict and Society is an essential source of reference material on the military conflicts that have defined global history from antiquity to today. Through absorbing investigations of how the World War I peace settlement led to World War II, or insightful comparisons of U.S. past involvement in Southeast Asia with the Afghanistan War, this database encourages study and research that goes beyond isolated events to identify causal relationships, chart historical developments, and analyze the role conflict itself plays in society. Content quality is maintained by an expert advisory board, comprised of educators and historians including Dr. Spencer Tucker (the award-winning author of titles such as The Encyclopedia of Middle East Wars and American Civil War: The Definitive Encyclopedia and Document Collection).This advisory board also serves to vet the database's original journal articles, which expose researchers to scholarly argumentation on controversial topics in global military history.

Book Summary: Wars create important turning points in human history, defining our leaders and changing the lives of ordinary families and citizens. Whether fighting for independence, forging alliances, making a play for dominance, or battling a global threat, nations shape history—and the world—when they go to war. World at War: Understanding Conflict and Society presents overviews of 50 wars, rebellions, and revolutions, both those commonly taught and those less so, and provides additional analysis of causes and consequences and portraits of opponents. The effect is to elucidate the global impact of these military conflicts that have defined our world from antiquity to today such that students and researchers may develop a deeper, critical appreciation of both the history of the world and the human costs of war.

The Chehalem Mountains area, encompassing 70 square kilometers, is at the western extent of the Columbia River Basalt Group as mapped in western Oregon. The flows in the study area were identified as belonging to subdivisions of the Columbia River Basalt Group on the basis of physical characteristics and trace element geochemistry. The basalt flows are poorly exposed in the area and weathering is deep and extensive where the flows have been exposed. Where erosion has exposed the underlying marine sedimentary rocks, the basalt has failed in landslides.

This thesis is a cultural tour of the Blue Mountains, New South Wales, Australia. It is concerned with the way in which Europeans employed stories to claim land and, conversely, their fears that the land would claim them.The stories considered are taken from literature and folk legend. The concept of liminality is important to the work because the mountains are a threshold, a demarcation between the city and the bush. Allied with the notion of liminality in the mountains is that of the uncanny (as defined by Freud). The work is divided into four sections. The first section, A POCKET GUIDE, introduces the terrain to be traversed. Section 2, FOUND, centres around the notion of foundation. Section 3, PASSAGE, links LOST and FOUND. LOST is the converse of FOUND. It explores our fears that the land will consume us.This fear is often expressed in the notion that the bush, beneath a surface beauty, has a dark and dangerous aspect and that it will swallow up the unwary. This idea is evident in the notion of possession - that a certain place can take hold of a person and induce a prescribed response from them - and of haunting, in which a spirit is tied to a specific location. / Doctor of Philosophy (PhD)

An understanding of the tectonic history of the Klamath Mountains is crucial for a valid paleogeographic reconstruction of the Pacific Northwest. However, prior to this study there were very few paleomagnetic (PM) data from the Klamath Mountains (KN), which resulted in conflicting interpretations about the role of the KM province in the tectonic evolution of western North America. Twenty-eight sites from five unmetamorphosed Middle Jurassic KM plutons with K-Ar ages ranging from 161 to 139 m.y.B.P. yielded stable PM results showing (1) a direction for the 160 in.y.B.P. Ashland pluton (D=324°, I=163°, α₉₅=8°, n=6) nearly concordant with the coeval expected direction (D=337°, 1=54°) and (2) clockwise rotated directions for the plutons of Grants Pass (D=045°, I=67°, α₉₅=12°, n=4), Greyback (D=083°,I=63°, α₉₅=9, n=9), and the Wooley Creek batholith and Slinkard pluton combined (D=037°, 160°, α₉₅=ll°, n=9). Tectonic interpretations of these PM data are difficult; two interpretations are offered to explain the observed directions. In the first, the mean PM direction of the four plutons with discordant directions (D=057°, 1=65°, α₉₅=7°, n=22) is restored to the expected 150 m.y.B.P. (the average K-Ar age for these four plutons) direction by rotation of a rigid block ~87° in a counterclockwise sense about a vertical axis (the possibility of tilt of these four plutons is disregarded in this interpretation). The Ashland pluton which shows no rotation is problematic. Either there was (is) a tectonic boundary west of the Ashland pluton, separating it from the rotation of the others, or the Ashland pluton was influenced both by clockwise rotation and tilt, the combined effect producing an essentially concordant PM direction. In the second interpretation we distinguish between the northern KN, intruded by the Grants Pas and Greyback Mountain plutons, and the southern region intruded by the Wooley Creek batholith and the Ashland and Slinkard plutons. The bases for this distinction are recent geologic and gravity studies which suggest that post-Middle Jurassic uplift of the domal Condrey Mountain Schist may have caused radially outward tilt of its adjacent terranes and plutons intruded therein, causing some of the observed discordances in their PM directions. Thus, in the second interpretation it is envisioned that (a) the northerly portion of the KM, intruded by the Grants Pass and Greyback plutons, was affected primarily by clockwise rotation about a vertical axis, and (b) discordant directions for the remaining plutons intruded farther south are due primarily to tilt in response to Condrey Mountain uplift. Based on the observed inclinations, there is no evidence of transport of the Klamath Mountain province along lines of longitude since Middle Jurassic time. Tectonic interpretations of the PM results of this study are consistent with significant post-Middle Jurassic clockwise rotation of the Klamath Mountains. The first interpretation above yields ~87° of clockwise rotation of the terrane examined. According to the second interpretation, a clockwise rotation of ~l00° is inferred from the average of the PM results of the northern Grants Pass and Greyback plutons. Therefore, 10° to 25° of clockwise rotation of the KM may have occurred prior to the formation of the Oregon Coast Range (~55 m.y.B.P.) and the two provinces may have rotated together since post-Lower Eocene time. / Graduation date: 1983

Terrestrial cosmogenic nuclides such as beryllium-10 have recently been used as a way to determine basin-average erosion rates around the world. These erosion rates are useful to geomorphologists investigating landscape evolution. The Hangay Mountains in Mongolia are a prime location to use beryllium-10 because of the granitic rocks that provide the quartz needed for cosmogenic analysis as well as the lack of observed evidence of recent or old mass wasting events that mobilize sediment and bedrock with much lower cosmogenic concentrations that cause underestimations of erosion rates. Basin-average erosion rates observed in seven basins across the eastern Hangay Mountains range from 12 m/My to about 20 m/My. These are of similar magnitude to those found in tectonically inactive regions such as the southern Appalachians. Comparing basin-average erosion rates to basin parameters, whole basin relief had the highest calculated R2 value and elevation had the lowest P-value. No strong relationships were seen between erosion rate and mean slope angle, hypsometric integral, area, or mean local relief. The basin-average erosion rates observed in the Hangay were compared to previous studies by Ahnert (1970), Portenga and Biernman (2011), and Matmon et al. (2009). We found erosion rates from the Hangay to be much lower than expected in our analyses. The differences in erosion rates from the Hangay Mountains compared to other places around the world are likely due to the fact that the streams in the Hangay are eroding into alluvium as opposed to bedrock, and are located in a landscape dominanted by diffusive hillslope sediment transport mechanisms. The erosion rate is limited to the amount of sediment that can be transported by the streams.
