The Role Of Forensic Anthropological Techniques In Identifying America's War Dead From Past Conflicts, William Belcher, Calvin Y. Shiroma, Lesley A. Chesson, Gregory E. Berg, Miranda Jans

Department of Anthropology: Faculty Publications

The Scientific Analysis Directorate of the U.S. Department of Defense's (DoD) Defense POW/MIA Accounting Agency (DPAA) is a unique entity within the U.S. Government. This agency currently houses the world's largest, accredited skeletal identification laboratory in the world, in terms of the size of the scientific staff, global mission, and number of annual identifications. Traditional forensic anthropology is used for the formation of a biological profile (biological sex, stature, population affinity/ancestry, and age) as well as trauma and pathologies that may be compared with historical records and personnel files. Since World War II, various scientists associated with DoD have conducted …

A Model-Based Exploratory Study Of Sulfur Dioxide Dispersions From Concentrated Animal Feeding Operations In The Southeastern United States, Jesse Winchester, Rezaul Mahmood, William Rodgers, Philip J. Silva, Nanh Lovanh, Joshua D. Durkee, John Loughrin

High Plains Regional Climate Center: Staff Publications

In the Southeastern U. S. there are Concentrated Animal Feeding Operations (CAFOs) that emit a variety of gases, including SO₂. Sulfur is emitted as reduced sulfur compounds and can react in the atmosphere to produce SO₂. It is expected that the concentra­tion and spread of SO₂ emissions from these sources would differ between wet and dry periods. In this research, SO₂ emissions from locations representing CAFOs and its dispersion over the south­eastern U.S. were simulated through sensitivity experiments using the Weather Research and Forecasting-Chemistry (WRF- Chem) model. Simulations were performed for dry periods and …

Temperamental Constellations And School Readiness: A Multivariate Approach, Andrew S. White, Kate M. Sirota, Scott R. Frohn, Sarah E. Swenson, Kathleen Moritz Rudasill

Department of Educational Psychology: Faculty Publications

This study uses canonical correlation analyses to explore the relationship between mul- tiple predictors of school readiness (i.e., academic readiness, social readiness, and teacher-child relationship) and multiple temperamental traits using data from the second wave (age 54 months, n = 1226) of the longitudinal Study of Early Child Care and Youth Development (SECCYD; NICHD ECCRN 1993). This longitudinal study collected data on a large cohort of children and their families from birth through age 15. For academic readiness, only one temperamental constellation emerged, representing the construct of effortful control (i.e., high attentional focusing, high inhibitory con- trol). For peer interactions, …

Bedbug Education, Treatment, And Prevention, Elizabeth Bedford

Department of Entomology: Distance Master of Science Projects

Cimex lectularius (bedbug) has become a severe issue in more recent years due to travel, immigration, and importation of products. Unfortunately, most people do not know their biology hence do not treat these arthropods correctly. Many myths and misinformation are currently available to people on the internet and with pest professionals. Education and proper treatment must eradicate these pests in homes, commercial buildings, and other places. To prove whether or not education with treatment garners better results,ten homes were treated with the same heating and chemical process, with only five being educated before, during and after. All homes were inspected …

Disrupted Identities And Forced Nomads: A Post-Disaster Legacy Of Neocolonialism In The Island Of Barbuda, Lesser Antilles, Sophia Perdikaris, Rebecca Boger, Edith Gonzalez, Emira Ibrahimpašić, Jennifer D. Adams

School of Global Integrative Studies: Faculty Publications

In the aftermath of the forced evacuation of the island of Barbuda due to Hurricane Irma, the Barbudan people have experienced an exile and return to a ‘new’ geographical, political, and economic context, albeit on the same island. With the specter of climate change and the potential impacts on island communities and nations, we use Barbuda, sister island of Antigua in the Lesser Antilles, to examine the trajectory of nomadic identities as they navigate changes that threaten contemporary land relationships and culture. Since its first permanent settlement in the 17th Century, the island geography of Barbuda has been fundamental to …

Department of Child, Youth, and Family Studies: Faculty Publications

The aim of this study was to describe the psychological and physical health needs of informal caregivers in a rehabilitation hospital and explore differences related to informal caregiver and care recipient characteristics. Readiness to engage in health promotion and perspectives on mindfulness meditation were assessed. Informal caregivers (N = 33) to patients receiving inpatient or outpatient treatment completed the Multidimensional Health Profile screening tools. Readiness to change was assessed using the readiness ruler approach. Almost half of participants (45.5%) had a chronic illness and 18.2% reported that it interferes with daily functioning. Low Positive Health Habits were reported by …

“Born Under My Heart”: Adoptive Parents’ Use Of Metaphors To Make Sense Of Their Past, Present, And Future, Lucas Hackenburg, Toni Morgan, Eve Brank

Center on Children, Families, and the Law: Faculty Publications

Metaphors provide the opportunity to make sense of our experiences and share them with others. The current research qualitatively examined interviews with adoptive parents who had adopted through intercountry or private adoptions. Throughout their interviews, each participant used at least one metaphor in describing their experiences of adopting and raising their child. Overarchingly, the metaphor of “Adoption is a journey” encapsulated parents’ experiences. To demonstrate the journey, parents used metaphors to describe the past, present, and future. Metaphors of the past focused on their child’s trauma and the origin of how the child came to join their family. Metaphors used …

Diets Of Double-Crested Cormorants In The Lake Winnebago System, Wisconsin, Ryan P. Koenigs, Daniel J. Dembkowski, Charles D. Lovell, Daniel A. Isermann, Adam D. Nickel

United States Department of Agriculture Wildlife Services: Staff Publications

Double-crested cormorant Phalacrocorox auritus Lesson (cormorant) populations have increased throughout the Great Lakes region of North America causing concern related to the impact of cormorant predation on fish communities. A recent decline in yellow perch Perca flavescens (Mitchill) abundance within the Lake Winnebago System, Wisconsin, USA, prompted an assessment of cormorant diets to evaluate potential effects of cormorant predation on the sportfish community. Diets were collected from 883 cormorants (417 from Lake Winnebago and 466 from Lake Butte des Morts) between 2015 and 2017. Cormorant diets on both waterbodies consisted mostly of freshwater drum Aplodinotus grunniens Rafinesque and gizzard shad …

Evaluation Of A Warfarin Bait For Controlling Invasive Wild Pigs (Sus Scrofa), James C. Beasley, Lindsay M. Clontz, Allison Rakowski, Nathan P. Snow, Kurt C. Vercauteren

United States Department of Agriculture Wildlife Services: Staff Publications

BACKGROUND: Wild pigs (Sus scrofa) cause widespread environmental and economic damage, and as a result are subjected to extensive control. Current management strategies have proven insufficient, and there is growing interest in use of toxicants to control invasive populations of this species. In 2017 a low-dose warfarin bait was federally approved for use in controlling wild pigs in the United States. However, no states have allowed use of this bait due to unanswered questions regarding welfare concerns, field efficacy, and non-target impacts.

RESULTS: All captive wild pigs fed 0.005% warfarin baits in no choice feeding trials succumbed in an average …

Relationship Between Urinary Energy And Urinary Nitrogen Or Carbon Excretion In Lactating Jersey Cows, D. L. Morris, Jeffrey L. Firkins, C. Lee, W. P. Weiss, Paul J. Kononoff

Department of Animal Science: Faculty Publications

Measurement of urinary energy (UE) excretion is essential to determine metabolizable energy (ME) supply. Our objectives were to evaluate the accuracy of using urinary N (UN) or C (UC) to estimate UE and ultimately improve the accuracy of estimating ME. Individual animal data (n = 433) were used from 11 studies with Jersey cows at the University of Nebraska–Lincoln, where samples were analyzed after drying (n = 299) or on an as-is basis (n = 134). Dried samples resulted in greater estimated error variance compared with as-is samples, and thus only as-is samples were used for final models. The as-is …

Ultrasound-Activated Ciliary Bands For Microrobotic Systems Inspired By Starfish, Cornel Dillinger, Nitesh Nama, Daniel Ahmed

Department of Mechanical and Materials Engineering: Faculty Publications

Cilia are short, hair-like appendages ubiquitous in various biological systems, which have evolved to manipulate and gather food in liquids at regimes where viscosity dominates inertia. Inspired by these natural systems, synthetic cilia have been developed and utilized in microfluidics and microrobotics to achieve functionalities such as propulsion, liquid pumping and mixing, and particle manipulation. Here, we demonstrate ultrasound-activated synthetic ciliary bands that mimic the natural arrangements of ciliary bands on the surface of starfish larva. Our system leverages nonlinear acoustics at microscales to drive bulk fluid motion via acoustically actuated small-amplitude oscillations of synthetic cilia. By arranging the planar …

Lysosomal Slc46a3 Modulates Hepatic Cytosolic Copper Homeostasis, Jung-Hwan Kim, Tsutomu Matsubara, Jaekwom Lee, Cristina Fenollar-Ferrer, Kyungreem Han, Donghwan Kim, Shang Jia, Christopher J. Chang, Heejung Yang, Tomokazu Nagano, Kristopher W. Krausz, Sun Hee Yim, Frank J. Gonzalez

Department of Biochemistry: Faculty Publications

The environmental contaminant 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) causes hepatic toxicity associated with prominent lipid accumulation in humans. Here, the authors report that the lysosomal copper transporter SLC46A3 is induced by TCDD and underlies the hepatic lipid accumulation in mice, potentially via effects on mitochondrial function. SLC46A3 was localized to the lysosome where it modulated intracellular copper levels. Forced expression of hepatic SLC46A3 resulted in decreased mitochondrial membrane potential and abnormal mitochondria morphology consistent with lower copper levels. SLC46A3 expression increased hepatic lipid accumulation similar to the known effects of TCDD exposure in mice and humans. The TCDD-induced hepatic triglyceride accumulation was significantly …

Transcriptomics Reveals The Putative Mycoparasitic Strategy Of The Mushroom Entoloma Abortivum On Species Of The Mushroom Genus Armillaria, Rachel A. Koch, Joshua R. Herr

Department of Plant Pathology: Faculty Publications

During mycoparasitism, a fungus—the host—is parasitized by another fungus—the mycoparasite. The genetic underpinnings of these relationships have been best characterized in ascomycete fungi. However, within basidiomycete fungi, there are rare instances of mushroom-forming species parasitizing the reproductive structures, or sporocarps, of other mushroom-forming species, which have been rarely investigated on a genetic level. One of the most enigmatic of these occurs between Entoloma abortivum and species of Armillaria, where hyphae of E. abortivum are hypothesized to disrupt the development of Armillaria sporocarps, resulting in the formation of carpophoroids. However, it remains unknown whether carpophoroids are the direct result of …

Genetic (Co)Variation And Accuracy Of Selection For Resistance To Viral Mosaic Disease And Production Traits In An Inter-Ecotypic Switchgrass Breeding Population, Serge J. Edmé, Gautam Sarath, Nathan Palmer, Gary Y. Yuen, Anthony A. Muhle, Rob Mitchell, Satyanarayana Tatineni, Christian Tobias

Department of Plant Pathology: Faculty Publications

Obtaining good accuracy and reliability of estimated breeding values is essential to increase the efficiency of a plant breeding program. Genetic variation was assessed for categorical (Virc) and binary (Virb) mosaic (caused by Panicum mosaic virus), dry matter (DMY) and predicted ethanol (Etoh) yields, and lignin content (Klason or KL, and acid-detergent or ADL) in a Summer–Kanlow switchgrass (Panicum virgatum L.) population. Breeding values were predicted with the restricted maximum likelihood–best linear unbiased prediction (REML-BLUP) approaches using a multivariate phenotypic (PBLUP) and animal (ABLUP) models, integrating a three-generation pedigree (1,622 half-sibs) in ABLUP and not in PBLUP. Models …

Poplar Allene Oxide Synthase 1 Gene Promoter Drives Rapid And Localized Expression By Wounding, Bin Lei, Christopher J. Frost, Tao Xu, Joshua Herr, John E. Carlson, Haiying Liang

Department of Plant Pathology: Faculty Publications

Promoters play critical roles in controlling the transcription of genes and are important as tools to drive heterologous expression for biotechnological applications. In addition to core transcription factor-binding motifs that assist in the binding of RNA polymerases, there are specific nucleotide sequences in a promoter region to allow regulation of gene expression. The allene oxide synthase (AOS) gene family are cytochrome P450s that are responsive to a variety of environmental stress, making them good candidates for the discovery of inducible promoters. Populus AOS homologs separate phylogenetically into two clades. Based on the 19 promoter motifs with significant abundance differences between …

Pratylenchus Smoliki, A New Nematode Species (Pratylenchidae: Tylenchomorpha) From The Great Plains Region Of North America, Thomas Powers, Timothy Todd, Tim Harris, Rebecca Higgins, Ann Macguidwin, Peter Mullin, Mehmet Ozbayrak, Kirsten Powers, Kanan Sakai

Department of Plant Pathology: Faculty Publications

Pratylenchus smoliki is a new species of root-lesion nematode described from corn-soybean production fields in the Central Great Plains of North America. It is characterized by populations with relatively abundant males, two lip annuli, females with a round functional spermatheca and a conoid to subcylindrical tail with a non-crenate, smooth terminus. In host preference tests, corn and wheat produce the largest nematode populations, whereas sorghum and soybeans produce less than 20% the numbers observed on corn. Scanning electron microscopy reveals that the en face patterns compare to those seen in Pratylenchus pseudocoffeae, P. scribneri, P. hexincisus, and …

The Interspecific Growth–Mortality Trade-Off Is Not A General Framework For Tropical Forest Community Structure, Sabrina E. Russo, Sean M. Mcmahon, Matteo Detto, Glenn Ledder, S.

Mohamad, Perry Ong, Anna Sugiyama, I-Fang Sun, Sylvester Tan, Jill Thompson, Takuo Yamakura, Sandra L. Yap, Jess K. Zimmerman

School of Biological Sciences: Faculty Publications

Resource allocation within trees is a zero-sum game. Unavoidable trade-offs dictate that allocation to growth-promoting functions curtails other functions, generating a gradient of investment in growth versus survival along which tree species align, known as the interspecific growth–mortality trade-off. This paradigm is widely accepted but not well established. Using demographic data for 1,111 tree species across ten tropical forests, we tested the generality of the growth–mortality trade-off and evaluated its underlying drivers using two species-specific parameters describing resource allocation strategies: tolerance of resource limitation and responsiveness of allocation to resource access. Globally, a canonical growth–mortality trade-off emerged, but the trade-off …

China’S Three Gorges Dam: Development, Displacement, And Degradation, Trent M. Carney

Nebraska Anthropologist

China’s state-led push towards modernization and enhanced economic growth has been marked by environmentally unsustainable practices, the results of which are still being combated today (Sapiro 2001). The construction of the Three Gorges Dam on the Yangtze River in Hubei province, China, represents the largest civil engineering project of the modern era. The dam is capable of generating one-sixth of China’s total electrical capacity; however, China’s attempts to go green come at a substantial cost. (Gleick 2009; Morgan & Waretini 2013; Paerl et al. 2011; Xu et al. 2013). Some of these consequences include increased geologic activity: the forced resettlement …

Impact Of Dietary Phytase On Tilapia Performance And Biofloc Water Quality, Bartholomew W. Green, Steven D. Rawles, Kevin K. Schrader, Matthew E. Mcentire, Jason Abernathy, Candis L. Ray, T. Gibson Gaylord, Miles D. Lange, Carl D. Webster

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

We tested the hypothesis that the fate of dietary phosphorus will not differ among a dicalcium phosphate-free practical diet treated with 6-phytase (3000 FTU/kg; Quantum Blue™; P-F + Phy), and positive (C) and negative (P-F) control practical diets when fed to hybrid tilapia (Oreochromis aureus x O. niloticus; 29.8 g initial weight) stocked at 29 fish/m³ and grown for 5 months to market size (454 g/fish) in outdoor biofloc production system tanks (16.6 m³). The ideal protein diets were formulated to contain 27.7% digestible protein and 4% lipid from practical ingredients and were extruded …

Patterns Of Genetic Variation In A Prairie Wildflower, Silphium Integrifolium, Suggest A Non-Prairie Origin And Locally Adaptive Variation, Andrew R. Raduski, Adam Herman, Cloe Pogoda, Kevin M. Dorn, David L. Van Tassel, Nolan Kane, Yaniv Brandvain

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

PREMISE: Understanding the relationship between genetic structure and geography provides information about a species’ history and can be used for breeding and conservation goals. The North American prairie is interesting because of its recent origin and subsequent fragmentation. Silphium integrifolium, an iconic perennial American prairie wildflower, is targeted for domestication, having undergone a few generations of improvement. We present the first application of population genetic data in this species to address the following goals: (1) improve breeding by characterizing genetic structure and (2) identify the species geographic origin and potential targets and drivers of selection during range expansion. METHODS: We …

James B Beard (24 Sept 1935 to 8 May 2018) can rightly be considered the “Father” of contemporary turfgrass science. During his career, he was known for setting a standard that provided the foundation for turfgrass science through his thorough approach to research, teaching, mentoring and communications. The books he published outlined a vision for an evolving scientific discipline. He trained and mentored >45 domestic and international doctoral and master students and numerous post-doctoral trainees, who in turn continued to raise the quality of contemporary turfgrass science in the USA and internationally. He led the effort to change the name …

High Plains Wheat Mosaic Virus: An Enigmatic Disease Of Wheat And Corn Causing The High Plains Disease, Satyanarayana Tatineni, Gary Hein

Department of Entomology: Faculty Publications

Brief history: In 1993, severe mosaic and necrosis symptoms were observed on corn (maize) and wheat from several Great Plains states of the USA. Based on the geographical location of infections, the disease was named High Plains disease and the causal agent was tentatively named High Plains virus. Subsequently, researchers renamed this virus as maize red stripe virus and wheat mosaic virus to represent the host and symptom phenotype of the virus. After sequencing the genome of the pathogen, the causal agent of High Plains disease was officially named as High Plains wheat mosaic virus. Hence, High Plains virus, …

Characterizing The Relationship Between Western Corn Rootworm (Coleoptera: Chrysomelidae) Larval Survival On Cry3bb1-Expressing Corn And Larval Development Metrics, Jordan D. Reinders, David S. Wangila, Emily Robinson, B. Wade French, Lance Meinke

Department of Entomology: Faculty Publications

The western corn rootworm, Diabrotica virgifera virgifera LeConte (Coleoptera: Chrysomelidae), is a significant pest of field corn, Zea mays L. (Poales: Poaceae), across the United States Corn Belt. Widespread adoption and continuous use of corn hybrids expressing the Cry3Bb1 protein to manage the western corn rootworm has resulted in greater than expected injury to Cry3Bb1-expressing hybrids in multiple areas of Nebraska. Single-plant bioassays were conducted on larval western corn rootworm populations to determine the level of resistance present in various Nebraska counties. The results confirmed a mosaic of susceptibility to Cry3Bb1 across Nebraska. Larval development metrics, including head capsule width …

Anth 110: Introduction To Anthropology: A Peer Review Of Teaching Benchmark Memo, Taylor A. Livingston

UNL Faculty Course Portfolios

This portfolio examines the extent to which the learning outcomes for Introduction to Anthropology (ANTH 110) were met through course assessments. The primary goal of this course is for students to engage with anthropological content, by introducing students to an anthropological perspective, which requires looking at issues from multiple contexts (holism), and having students add this to their “tool kit” to help them make sense of what they believe, why they believe it, and how to make sense of the world around them and their place in it. The alignment of outcomes and assessment was analyzed through an examination of …
