Bioshock And Bioshock 2: A Case Study Of Tragic Posthumans, Madison Knight

Dialogue: The Interdisciplinary Journal of Popular Culture and Pedagogy

Video games offer unique perspectives when analyzing the social structures built into the world of a text; choice becomes a major factor in the central action of video games as players take control of the story’s main protagonists. Two video games that fixate on this idea of choice and its intersection with the posthuman are Ken Levine’s BioShock (2007) and its direct successor, Jordan Thomas’s BioShock 2 (2010). The games each feature posthuman protagonists. Posthumans themselves are often prejudiced and portrayed to be “other,” and while BioShock equally asserts posthumans as “others,” these games show a different side to the …

Escaping The Pedagogical Cabin In The Woods, Tony Kemerly, Davis Ritenour

Dialogue: The Interdisciplinary Journal of Popular Culture and Pedagogy

The American educational system, because of its seemingly innocuous yet ubiquitous nature, has become, to borrow a term from Roland Barthes, naturalized. By being naturalized, it has become a system that has somehow slipped beneath the radar of the American populace and operates on an autopilot of sorts that allows it to employ practices that don’t necessarily have the best interests of its constituents at heart. Murray Rothbard (1979) argued that compulsory schooling is not guided by altruism, but rather a desire to coerce the population into a mold that is desired by those possessing power in society. This need …

Seeing The Strange: Science Fiction, Critical Pedagogy, And Future Teachers, Jeremy Delamarter

Dialogue: The Interdisciplinary Journal of Popular Culture and Pedagogy

Critical pedagogy, which is the branch of critical theory devoted to uncovering hidden power differentials in educational settings, is too often taught in abstract terms, and future educators fail to understand its relevance to praxis in their future classrooms. As a genre, science fiction is particularly adept at helping students consider the power structures and dynamics occasioned by scientific advances. Even more specifically, science-fiction is a powerful tool for teaching future educators the fundamentals of critical pedagogy. This article provides a philosophical exploration of why science fiction is such a useful tool for teaching critical pedagogy and uses the specific …

A Statewide Geographic Information System (Gis) As A Predictive Tool For Locating Deeply Buried Archeological Deposits In Nebraska: Phase Iii-The Sandhills Region, Anthony L. Layzell, Rolfe D. Mandel, John Swigart, David T. Williams

Nebraska Department of Transportation: Research Reports

This project developed a GIS to assist with the identification of deeply buried cultural deposits in alluvial settings across the Sandhills region of Nebraska. Soil survey data, previous geoarchaeological investigations, landform position, and other information was used to rank the potential of any stream valley setting as low, low-moderate, moderate-high, or high potential to contain buried cultural deposits. While the presence of buried soils does not necessarily translate to presence of buried archeological sites, the potential for such sites is far greater in buried soils. The GIS can be used by NDOT and other agencies with statutory historic preservation obligations, …

Two Birds, Two Stones: Separating Biodiversity Conservation From Patent Law, Jessie Sadlon

Nebraska Law Bulletin (Selected Issues)

The current decline in biodiversity is faster than any other point in human history.[1] Overexploitation is the leading driver of biodiversity loss; species are harvested at unreplenishable rates. Government, non-government, and industry representatives are searching for direction in addressing this rapid species loss. In particular, the World Intellectual Property Organization (“WIPO”) is looking to channel biodiversity conservation through patent systems by instituting an origin disclosure requirement within the patent application process. This paper explores the intersection of biodiversity and innovation, contending the origin disclosure requirement is an unjustified, ineffective mechanism to effectuate biodiversity conservation.

Part II describes the biodiversity crisis …

Chilling- And Dark-Regulated Photoprotection In Miscanthus, An Economically Important C4 Grass, Jared Haupt, Katarzyna Glowacka

Department of Biochemistry: Faculty Publications

Tolerance of chilling dictates the geographical distribution, establishment, and productivity of C4 crops. Chilling reduces enzyme rate, limiting the sink for the absorbed light energy leading to the need for quick energy dissipation via non-photochemical quenching (NPQ). Here, we characterize NPQ upon chilling in three Miscanthus accessions representing diverse chilling tolerance in C4 grasses. High chilling tolerant accessions accumulate substantial amounts of zeaxanthin during chilling nights in both field and growth chamber settings. Chilling-induced zeaxanthin accumulation in the dark enhances rate of NPQ induction by 66% in the following morning. Based on our data, the emerging ways for the unique …

The Case For E15: A Cheaper, Cleaner Fuel, Cassidy Skillett

Op-Eds from ENSC230 Energy and the Environment: Economics and Policies

In its name, “E” indicates that the fuel contains ethanol and “15” communicates that 15% of the gasoline blend is ethanol. When Nebraskan drivers pull up to the gas station, they can buy cheaper and cleaner E15. In 43 states - drivers are not so lucky. A new bill would end fuel discrimination of E15 at refueling stations nationwide.

This change is long overdue and would allow E15 to be available year-round in all states rather than just during the winter.

Impact Of Irrigation Systems On Water Use And Water Productivity: A Case Study Using Aquacrop In Khartoum, Sudan, Abdalhakam Almagzoop

Department of Agricultural and Biological Systems Engineering: Masters Project Reports

Water scarcity significantly challenges agricultural productivity in arid regions like Khartoum, Sudan. This study evaluates the impact of three irrigation systems—furrow, sprinkler, and surface drip—on the water use and productivity of sorghum (Sorghum bicolor L.) under different climatic conditions using the AquaCrop model. Simulations were conducted for three representative years: a wet year (2022), a normal year (2015), and a dry year (2018). The results demonstrate that irrigation substantially improved water use efficiency and crop yield compared to non-irrigated (rainfed) conditions. Rainfed crops resulted in lower biomass, harvest index, and yield, particularly in the dry year, highlighting the importance …

Current storage solutions are not viable on a global scale due to material scarcity, safety concerns, and high capital costs. Among emerging technologies, zinc-air batteries (ZABs) have garnered significant interest. ZABs offer a theoretical energy density five times greater than traditional lithium-ion batteries, utilize safe …

Impacts Of Stream Bed Adjustment On Local Bridge Morphology At Highway 281, Molly G. Likins

Department of Civil and Environmental Engineering: Dissertations, Theses, and Student Research

Nebraska sand-bed rivers have long been a part of sediment transport studies and have been used in the development of numerous well-known empirical bedload equations. Some of these studies have shown how adjustments in streambed elevation led to changes in local stream morphology. The sand-bed rivers of Nebraska are highly susceptible to such changes due to their wide, shallow cross-sections and erodibility. The objective of our study is to synthesize a hydrodynamic model with high-resolution field data and improved methods of representing sediment transport to better predict both short and long-term channel adjustments for an aggraded sand-bed river.

Development And Evaluation Of Highly Thixotropic Uhpc Mixtures For Bridge Overlay Applications, Akbota Aitbayeva

Department of Civil and Environmental Engineering: Dissertations, Theses, and Student Research

Ultra-high-performance concrete (UHPC) is an advanced construction material renowned for its exceptional strength and durability. However, conventional UHPC is typically self-consolidating, making it unsuitable for bridge deck overlay applications due to challenges posed by potential surface slopes. UHPC overlay construction requires a highly thixotropic material that not only responds well to vibration but also maintains workability over an extended period and remains stable on sloped surfaces. Despite the complex rheological properties of highly thixotropic UHPC, limited testing methods are available to effectively assess the workability and rheology of overlay mixtures. To address this gap, the present study provides a comprehensive …

Channel Estimation In Millimeter Wave Mimo Systems: The Tensor-Based Methods, Fei He

Dissertations and Doctoral Documents, University of Nebraska-Lincoln, 2023–

This dissertation presents two novel tensor-based methods for solving channel estimation (CE) problems in Millimeter Wave (mmWave) multiple-input multiple-output (MIMO) wireless communication systems. First, we proposed a method of tensor rank regularization with bias compensation for CE in a hybrid mmWave MIMO system. We modified the CANDECOMP/PARAFAC(CP) decomposition-based method and jointly estimated the tensor rank and channel factor matrices. It differs from most existing works by assuming that the number of channel paths is unknown, yet it can accurately estimate channel parameters without prior knowledge of the number of multipath components. The tensor rank is estimated by a novel sparsity-promoting …
