Artistic Syncretism In Latin America: From Olmec To Spanish Colonialism, Nicole Timm

Honors Program: Senior Projects (Public)

The purpose of this paper is to provide a historic and systematic review of colonial Latin American art. The first half will focus on the ancient arts created by the ancient civilizations that sculpted culture in Latin America centuries before the Spanish were aware another continent existed. The latter portion of the paper will look to the post-colonial period. It will begin by delving into the influence of European artistic styles blending with Latin American culture and style of painting and vice versa. The final goal of this paper is to uncover the syncretism that took place across Latin America …

Earth System Models (ESMs) are essential tools for understanding and predicting global change, but they cannot explicitly resolve hillslope‐scale terrain structures that fundamentally organize water, energy, and biogeochemical stores and fluxes at subgrid scales. Here we bring together hydrologists, Critical Zone scientists, and ESM developers, to explore how hillslope structures may modulate ESM grid‐level water, energy, and biogeochemical fluxes. In contrast to the one‐dimensional (1‐D), 2‐ to 3‐mdeep, and free‐draining soil hydrology in most ESM land models, we hypothesize that 3‐D, lateral ridge‐to‐valley flow through shallow and deep paths and insolation contrasts between sunny and shady slopes are the top …

Newgeochemical Evidence For The Origin Of North America's Largest Dune Field, The Nebraska Sand Hills, Central Great Plains, Usa, Daniel R. Muhs, James R. Budahn

United States Geological Survey: Staff Publications

The Nebraska SandHills region is the largest dune field inNorthAmerica and has diverse aeolian landforms. It has been active during both the late Pleistocene and late Holocene. Despite decades of study, the source of sediment for this large sand sea is still controversial. Here we report new trace element compositions of aeolian sand that are compared to four hypothesized sediment sources, Tertiary rocks of the Arikaree Group and Ogallala Group, unconsolidated sands of Pliocene age, and Platte River systemsands. All four potential sources have amineralogy that is similar to the Nebraska Sand Hills. K/Rb, K/Ba, Sc-Th-La, Eu/Eu*, LaN/YbN, As/Sb, and …

Blood Parasites Infecting The Hoatzin (Opisthocomus Hoazin), A Unique Neotropical Folivorous Bird, M. Andreína Pacheco, M. Alexandra García-Amado, Jaime Manzano, Nubia E. Matta, Ananias A. Escalante

Harold W. Manter Laboratory of Parasitology: Library Materials

The Hoatzin (Opisthocomus hoazin) is the only extant member of the order Opisthocomiformes. This unique South American bird lives in the riparian lowland vegetation characteristic of the Amazon and Orinoco basins. Hoatzins nest in communal social units close to water bodies; they are strictly folivores being the only bird with pregastric fermentation in the crop. Because of the complex logistics involved in capturing this bird, there is a knowledge gap on its parasites. This study documents two distant lineages of haemosporidian parasites (Plasmodium spp.) in a juvenile and two adults sampled in the Cojedes state, Venezuela. Although …

Soil Moisture Monitoring Using Remote Sensing Data And A Stepwise-Cluster Prediction Model: The Case Of Upper Blue Nile Basin, Ethiopia, Getachew Ayehu, Tsegaye Tadesse, Berhan Gessesse, Yibeltal Yigrem

National Drought Mitigation Center: Faculty Publications

In this study, a residual soil moisture prediction model was developed using the stepwise cluster analysis (SCA) and model prediction approach in the Upper Blue Nile basin. The SCA has the advantage of capturing the nonlinear relationships between remote sensing variables and volumetric soil moisture. The principle of SCA is to generate a set of prediction cluster trees based on a series of cutting and merging process according to a given statistical criterion. The proposed model incorporates the combinations of dual-polarized Sentinel-1 SAR data, normalized difference vegetation index (NDVI), and digital elevation model as input parameters. In this regard, two …

Chronology Of Dune Development In The White River Badlands, Northern Great Plains, Usa, P. E. Baldauf, P. A. Burkhart, Paul R. Hanson, M. Miles, Ashley Larsen

School of Natural Resources: Faculty Publications

Aeolian dune field chronologies provide important information on drought history on the Great Plains. The White River Badlands (WRB) dunes are located approximately 60 km north of the Nebraska Sand Hills (NSH), in the western section of the northern Great Plains. Clifftop dunes, sand sheets, and stabilized northwest-southeast trending parabolic dunes are found on upland mesas and buttes, locally called tables. The result of this study is a dune stabilization history determined from samples collected from stratigraphic exposures and dune crests. Thirty-seven OSL ages, from this and previous investigations, show three periods of dune activity: 1) ~21,000 years ago to …

Twenty-Three Unsolved Problems In Hydrology (Uph) – A Community Perspective, Günter Blöschl, Christopher M. U. Neale, A Cast Of Thousands

Daugherty Water for Food Global Institute: Faculty Publications

This paper is the outcome of a community initiative to identify major unsolved scientific problems in hydrology motivated by a need for stronger harmonisation of research efforts. The procedure involved a public consultation through online media, followed by two workshops through which a large number of potential science questions were collated, prioritised, and synthesised. In spite of the diversity of the participants (230 scientists in total), the process revealed much about community priorities and the state of our science: a preference for continuity in research questions rather than radical departures or redirections from past and current work. Questions remain focused …

Islamophobia In U.S. Education, Shabana Mir, Loukia K. Sarroub

Department of Teaching, Learning, and Teacher Education: Faculty Publications

Anti-Muslim sentiment has grown in scale and visibility far beyond its association with the horrific attacks of 2001. The US government’s “War on Terror,” which began after the attacks, often pervades the domestic landscape as a war on Islamic religious “extremism.” The definitions and content of such religious extremism are so extensive that they encompass large numbers of Muslims, and they highlight Muslims as being inherently problematic. For example, the success of the 2016 presidential campaign can be said to have relied significantly on a right-wing Islamophobic fear-mongering that shariah was set to take over the US. As we grappled …

Grain Yield, Crop And Basal Evapotranspiration, Production Functions And Water Productivity Response Of Drought-Tolerant And Non-Drought-Tolerant Maize Hybrids Under Different Irrigation Levels, Population Densities And Environments: Part Ii. In South-Central And Northeast Nebraska's Transition Zone And Sub-Humid Environments, Suat Irmak, Ali T. Mohammed, William Kranz

Department of Agricultural and Biological Systems Engineering: Faculty Publications

Information and data on newer drought-tolerant maize hybrid response to water in different climates are extremely scarce. This research quantified the performance of non-drought-tolerant (NDT) (H1) and drought-tolerant (DT) (H2, H3, and H4) maize (Zea mays L.) hybrids response to grain yield, crop evapotranspiration (ETc), basal evapotranspiration (ETb), ETc-yield production functions (ETYPF), and crop water use efficiency (CWUE) at three irrigation levels and two plant population densities (PPDs) at two locations (transition zone between sub-humid and semiarid climates at Clay Center (SCAL), Nebraska, in 2010 and 2012; and in a sub-humid climate at Concord (HAL), Nebraska, in 2010, 2011, and …

Closing Yield Gaps For Rice Self-Sufficiency In China, Nanyan Deng, Patricio Grassini, Haishun Yang, Jianliang Huang, Kenneth G. Cassman, Shaobing Peng

Department of Agronomy and Horticulture: Faculty Publications

China produces 28% of global rice supply and is currently self-sufficient despite a massive rural-to-urban demographic transition that drives intense competition for land and water resources. At issue is whether it will remain self-sufficient, which depends on the potential to raise yields on existing rice land. Here we report a detailed spatial analysis of rice production potential in China and evaluate scenarios to 2030. We find that China is likely to remain self-sufficient in rice assuming current yield and consumption trajectories and no reduction in production area. A focus on increasing yields of double-rice systems on general, and in three …

An Information Theory-Based Approach To Assessing Spatial Patterns In Complex Systems, Tarsha Eason, Wen Ching-Chuang, Shana Sundstrom, Heriberto Cabezas

School of Natural Resources: Faculty Publications

Given the intensity and frequency of environmental change, the linked and cross-scale nature of social-ecological systems, and the proliferation of big data, methods that can help synthesize complex system behavior over a geographical area are of great value. Fisher information evaluates order in data and has been established as a robust and effective tool for capturing changes in system dynamics, including the detection of regimes and regime shifts. The methods developed to compute Fisher information can accommodate multivariate data of various types and requires no a priori decisions about system drivers, making it a unique and powerful tool. However, the …

The Cost Of Forest Preservation In The Brazilian Amazon: The “Arc Of Deforestation”, Felipe De Figueiredo Silva, Lilyan E. Fulginiti, Richard Perrin

Department of Agricultural Economics: Faculty Publications

We estimate the trade-off between agricultural production and forest preservation for the municipalities in Brazil’s agricultural frontier, the so-called “arc of deforestation,” using census and deforestation data for 2006. We use a nonparametric directional output distance function that allows us to identify the gradients of the production possibility frontier, which are the trade-offs of interest. We found that, on average, $979 is forgone in annual livestock, timber, and grain revenues to conserve 1 hectare of forest. This translates, ceteris paribus, to an average present value of costs to permanently sequester CO2 of $16.36/t, higher than most previous estimates.

The Opportunity Cost Of Preserving The Brazilian Amazon Forest, Felipe De Figueiredo Silva, Richard Perrin, Lilyan E. Fulginiti

Department of Agricultural Economics: Faculty Publications

We estimate the trade-off between forest preservation and agricultural production for the Legal Amazon region, using census and deforestation

data for municipalities in 2006.We use a directional distance function to represent the production possibility frontier, and then calculate the shadow

price of reducing deforestation in terms of agricultural income foregone. Results indicate that, on average, to preserve 1 ha of forest, $797 in annual

agricultural GDP must be foregone. Using a discount rate of 10% and average forest carbon density of 132 tons per hectare, these results imply an

average shadow price of $16 per ton of CO2 permanently sequestered.

The Importance Of Frankfurt Printing Before 1550. Sebald Beham Moves From Nuremberg To Frankfurt, Alison Stewart

School of Art, Art History, and Design: Faculty Publications and Creative Activity

Five hundred years ago, Sebald Beham had reasons enough to leave Nuremberg and more than enough reasons to move to Frankfurt. That town's attraction as a printing center became one of the factors that resulted in Beham's settling permanently in the city on the Main in 1531, leaving behind his home town of Nuremberg, best known as the artistic center of the Renaissance master Albrecht Durer. Despite the high regard the Franconian town and Durer received, the authorities there did not treat other painters in Durer's circle particularlywell. The dubbing of Beham as 'godless painter' in 1525 constituted one of …

Background: Workplace or campus wellness/obesity-prevention policies and initiatives can improve health. Research tools to assess worksite or campus policies/initiatives are scarce. Thus, the aim of this research is to develop and validate the policies, opportunities, initiatives, and notable topics (POINTS) audit. Methods: POINTS was developed and refined via expert review, pilot-testing, and field testing. Trained researchers completed a web-based review from a student-focus or employee-focus regarding 34 health-promoting topics for colleges. Each topic was evaluated on a 0–2 scale: 0 = no policy/initiative, 1 = initiatives, 2 = written policy. When a written policy was detected, additional policy support questions …

Delineating A Regional Education Research Agenda, Edmund T. Hamann

Department of Teaching, Learning, and Teacher Education: Faculty Publications

If one wants to advance the argument that the Great Plains, as a region, matters— and the very existence of Great Plains Research and the Center for Great Plains Studies that publishes it suggest significant support for the idea— then one can ask, How did we learn that they matter? How do they matter? Can we live on them ethically, with a regard for each other and sense of stewardship and responsibility? Education research in, of, for, and with a region allows us to pursue each of these questions, plus more. Here we do so, informed by the two central …
