Slope Stability Models For Rainfall-Induced Lahars During Long-Lasting Eruptions, V Baumann, C Bonadonna, S Cuomo, M Moscariello, I Manzella

School of Geography, Earth and Environmental Sciences

In this study we analyse the spatial distribution of potential lahar sources during long-lasting eruptions using two slope stability models (SHALSTAB and TRIGRS). The analysis is based on observed deposit grain-size and thickness, rainfall data and slope angle of the lahar events, in the area surrounding the Cordón Caulle volcano, Chile, that occurred during the 2011 eruption. The main phase of the eruption (4–7 June) was characterized by eruptive plumes from 7 to 11 km high which dispersed most of the tephra eastward toward Argentina, with a total estimated volume of about 1 km3. Tephra-fallout blanketed the region from ESE …

Why couldn't the United States stay out of this area? The answer lies in three phases of international life. We are involved because of (I) geography, (II) world economy and (Ill) certain cultural factors that can best be described in psychocultural terms.

Pre-Boomer Students On Campus: An Exploratory Study Of How Students Born Before 1946 Experience The Youth-Oriented Campus Culture At Unm, Elinor Sue Coates Phd

Organization, Information and Learning Sciences ETDs

Older learners have been studied thoroughly, except for those born before 1946, preceding the post-war "population bulge" (Carlson, 2008; Laditka, Fischer, Laditka, & Segal, 2004; Verstynen, 2011). Most such studies define "older" as over 25 or over 40, and fail to separate the subject group from those who came later. Defining a group by numerical age is problematic because it changes every year and soon omits the group's defining life experiences (Pilcher, 1994), which for this group include the Great Depression, World War II, the polio epidemic, and life before television. To address that gap this critical ethnography explored the …

Impact Of Suburban Landscape Features On Gene Flow Of The Model Invasive Grass, Brachypodium Sylvaticum, Tina Marie Arredondo

Dissertations and Theses

Rapid range expansion of newly invasive species provides a unique opportunity for studying patterns of dispersal and gene flow. In this thesis, I examined the effect of landscape features on gene flow in the invasive grass Brachypodium sylvaticum at the edge of its expanding range. I used genome-wide Single Nucleotide Polymorphism (SNP) surveys of individuals from 22 locations in the Clackamas Watershed in the Portland, Oregon metropolitan region to assess genetic diversity and structure, to identify putative source populations, and to conduct landscape genetic analyses. Resistance surfaces were created for each landscape feature, using ResistanceGA to optimize resistance parameters. My …

Differential Responses Of Carbon-Degrading Enzyme Activities To Warming: Implications For Soil Respiration, Ji Chen, Yiqi Luo, Pablo García-Palacios, Junji Cao, Marina Dacal, Xuhui Zhou, Jianwei Li, Jianyang Xia, Shuli Niu, Huiyi Yang, Shelby Shelton, Wei Guo, Kees Jan Van Groenigen

Agricultural and Environmental Sciences Faculty Research

Extracellular enzymes catalyze rate-limiting steps in soil organic matter decomposition, and their activities (EEAs) play a key role in determining soil respiration (SR). Both EEAs and SR are highly sensitive to temperature, but their responses to climate warming remain poorly understood. Here, we present a meta-analysis on the response of soil cellulase and ligninase activities and SR to warming, synthesizing data from 56 studies. We found that warming significantly enhanced ligninase activity by 21.4% but had no effect on cellulase activity. Increases in ligninase activity were positively correlated with changes in SR, while no such relationship was found for cellulase. …

Grafting Democracy: British Policy In The Burma Independence Process, Kylan Rutherford

Undergraduate Honors Theses

This thesis investigates—through a case study of the independence process in Burma—what, if any, specific policies the British established and followed in granting independence to their former colonies. The author investigates the development of institutions in the first Burma constitution through primary source documents. Statements of policy found indicate that the British strove to create a policy of protection and representation of minorities, encouragement of democracy mirroring Western constitutions, and a desire to establish stability in the region and preserve self-interests. Documents indicate a large disparity between policy and practice. The author concludes that this disparity is caused primarily by …

Impacts Of Agricultural Expansion (1910s-2010s) On Water Cycle In The Songneng Plain, Northeast China, Lijuan Zhang, Cuizhen Wang, Xiaxiang Li, Hongwen Zhang, Wenliang Li, Lanqi Jiang

Faculty Publications

Agricultural expansion is one of the primary land use changes on the Earth’s surface. The Songnen Plain in Northeast China is renowned for its Black Soil and is one of the most important agricultural regions of this country. In the last century, its population increased 20-fold and excessive areas of grassland were cultivated. Based on a series of decadal land use/land cover data sets in the plain (1910s–2010s), this study simulated the water balance in each decade using the Weather Research and Forecasting (WRF) model and assessed the water effects of centurial agricultural expansion. Six variables were simulated to explain …

This thesis addresses Constantine's developments of the Roman province of Palaestina. It analyzes two important Christian bishops, Eusebius of Caesarea and Cyril of Jerusalem, and one nameless Christian traveler, the Bordeaux pilgrim, to illuminate how fourth-century Christians understood these developments. This study examines the surviving writings of these Christian authors: the Bordeaux Itinerary, Cyril's Catechetical Lectures, and Eusebius's Ecclesiastical History, Onomasticon, Preparation of the Gospel, Proof of the Gospel, and the Life of Constantine, and the archaeological remains of several Constantinian basilicas to interpret their views of the imperial attentions that were being poured …

Measurement Of Methylamines In Seawater Using Solid Phase Microextraction And Gas Chromatography, Mark F. Fitzsimons, Charlotte H.L. Cree, Ruth Airs, Stephen D. Archer

School of Geography, Earth and Environmental Sciences

The methylamines form part of the marine organic nitrogen pool. Although they are ubiquitous in marine systems, little is known about their distribution, production and fate in the marine environment. Analytical methods have been developed for their analysis in marine waters, but these have employed custom-made apparatus, limiting data to a few studies. Here, we report a method developed for the determination of methylamines in seawater which combines headspace solid phase micro-extraction (SPME) and gas chromatography with selective nitrogen detection. Gaseous methylamines were pre-concentrated from water samples (approximately 1 L) at elevated temperature, onto a polydimethylsiloxane/divinylbenzene SPME fibre. The analytes …

Sediment Characteristics And Methane Ebullition In Three Subarctic Lakes, Martin Wik, Joel E. Johnson, Patrick M. Crill, Joel P. Destasio, Lance Erickson, Madison J. Halloran, Maria Florencia Fahnestock, Maurice K. Crawford, Stephen C. Phillips, Ruth K. Varner

Faculty Publications

Ebullition (bubbling) from climate‐sensitive northern lakes remains an unconstrained source of atmospheric methane (CH4). Although the focus of many recent studies, ebullition is rarely linked to the physical characteristics of lakes. In this study we analyze the sediments of subarctic postglacial lakes and investigate how sediment properties relate to the large spatial variation in CH4 bubble flux, quantified over multiple years using bubble traps. The results show that the sediments from our lakes are rich in total organic carbon, containing 37 kg/m3 on average. This number is roughly 40% higher than the average for yedoma deposits, which have been identified …

Non-Gnss Smartphone Pedestrian Navigation Using Barometric Elevation And Digital Map-Matching, Daniel J. Broyles, Kyle J. Kauffman, John F. Raquet, Piotr Smagowski

Faculty Publications

Pedestrian navigation in outdoor environments where global navigation satellite systems (GNSS) are unavailable is a challenging problem. Existing technologies that have attempted to address this problemoften require external reference signals or specialized hardware, the extra size,weight, power, and cost of which are unsuitable for many applications. This article presents a real-time, self-contained outdoor navigation application that uses only the existing sensors on a smartphone in conjunction with a preloaded digital elevation map. The core algorithm implements a particle filter, which fuses sensor data with a stochastic pedestrian motion model to predict the user’s position. The smartphone’s barometric elevation is then …

Multilevel Governance: Framing The Integration Of Top-Down And Bottom-Up Policymaking, George C. Homsy, Zhilin Liu, Mildred E. Warner

Public Administration Faculty Scholarship

Scholars embrace multilevel governance as an analytical framework for complex problems, such as climate change or water pollution. However, the elements needed to comprehensively operationalize multilevel governance remain undefined in the literature. This paper describes the five necessary ingredients to a multilevel framework: sanctioning and coordinating authority, provision of capacity, knowledge co-production, framing of co-benefits, and inclusion of civil society. The framework’s analytical utility is illustrated through two contrasting case examples – watershed management in the U.S. and air quality management in China. The framework balances local and central actors, which can promote a more effective governance regime.

Aurel Stein And The Kiplings: Silk Road Pathways Of Converging And Reciprocal Inspiration, Geoffrey Kain

Publications

Biographies of the renowned linguistic scholar and archaeological explorer Sir Marc Aurel Stein (1862–1943) inevitably yet briefly refer to the role played by John Lockwood Kipling (1837–1911), as curator of the Lahore Museum—with its extensive collection of ancient Gandharan Greco-Buddhist sculpture—in exciting Stein’s interests in and theories of what likely lay buried under the sands of the Taklamakan Desert. A more insistent focus on the coalescing influences in the Stein-Kipling relationship, including a subsequent line of evident inspiration from Stein to the internationally famed author and Nobel laureate Rudyard Kipling (Lockwood’s son; 1865–1936), helps to synthesize some of the highlights …

Numeracy

Nathan D. Grawe. 2018. Demographics and the Demand for Higher Education (Baltimore: John Hopkins University Press). 175 pp. ISBN 9781421424132.

Grawe introduces the Higher Education Demand Index (HEDI), a new probabilistic model designed to produce more nuanced forecasts of college attendance in the US than one-dimensional predictions based on the declining number of 18 year-olds. Using HEDI, Grawe confirms that nationwide attendance at both 2-year and 4-year schools is likely to decline over the next decade, but that the nature of this decline will vary by type of institution, geography, race and ethnicity, and parental income and education levels; some …
