When Baseball Went White, Ryan A. Swanson

University of Nebraska Press: Sample Books and Chapters

The story of Jackie Robinson valiantly breaking baseball’s color barrier in 1947 is one that most Americans know. But less recognized is the fact that some seventy years earlier, following the Civil War, baseball was tenuously biracial and had the potential for a truly open game. How, then, did the game become so firmly segregated that it required a trailblazer like Robinson? The answer, Ryan A. Swanson suggests, has everything to do with the politics of “reconciliation” and a wish to avoid the issues of race that an integrated game necessarily raised. The history of baseball during Reconstruction, as Swanson …

Native Diasporas, Gregory D. Smithers, Brooke N. Newman

University of Nebraska Press: Sample Books and Chapters

The arrival of European settlers in the Americas disrupted indigenous lifeways, and the effects of colonialism shattered Native communities. Forced migration and human trafficking created a diaspora of cultures, languages, and people. Gregory D. Smithers and Brooke N. Newman have gathered the work of leading scholars, including Bill Anthes, Duane Champagne, Daniel Cobb, Donald Fixico, and Joy Porter, among others, in examining an expansive range of Native peoples and the extent of their influences through reaggregation. These diverse and wide-ranging essays uncover indigenous understandings of self-identification, community, and culture through the speeches, cultural products, intimate relations, and political and legal …

Bold They Rise, David Hitt, Heather R. Smith

University of Nebraska Press: Sample Books and Chapters

After the Apollo program put twelve men on the moon and safely brought them home, anything seemed possible. In this spirit, the team at NASA set about developing the Space Shuttle, arguably the most complex piece of machinery ever created. The world’s first reusable spacecraft, it launched like a rocket, landed like a glider, and carried out complicated missions in between. Bold They Rise tells the story of the Space Shuttle through the personal experiences of the astronauts, engineers, and scientists who made it happen—in space and on the ground, from the days of research and design through the heroic …

Anthropologists And Their Traditions Across National Borders, Regna Darnell, Frederic W. Gleach

University of Nebraska Press: Sample Books and Chapters

Two Hawk Dreams, Lawrence L. Loendorf, Nancy Medaris Stone

University of Nebraska Press: Sample Books and Chapters

Bighorn sheep graze on the last of the green grass on Gets-Struck-By-Lightning Mountain in the late fall. Two Hawk’s father and older brother, Night Heron, set off through newly fallen snow to hunt with their dogs. Two Hawk is sad to be left behind, but he has heard the bull elk’s mating call for only seven seasons, too few to be old enough to hunt.

So begins another day for a boy of the Tukudika (Sheep Eater) Shoshones, living in the traditional ways in what will one day be known as Yellowstone National Park. Two Hawk is learning those ways, …

Uses Of Plants By The Hidatsas Of The Northern Plains, Gilbert Livingston Wilson

University of Nebraska Press: Sample Books and Chapters

In 1916 anthropologist Gilbert L. Wilson worked closely with Buffalobird-woman, a highly respected Hidatsa born in 1839 on the Fort Berthold Reservation in western North Dakota, for a study of the Hidatsas’ uses of local plants. What resulted was a treasure trove of ethnobotanical information that was buried for more than seventy-five years in Wilson’s archives, now held jointly by the Minnesota Historical Society and the American Museum of Natural History in New York City. Wilson recorded Buffalobird-woman’s insightful and vivid descriptions of how the nineteenth-century Hidatsa people had gathered, prepared, and used the plants and wood in their local …

Frequency-Dependent Mate Selection In The Guppy (Poeciliidae: Poecilia Reticulata), Andre Porter, Jack Frankel

Department of Biology Faculty Publications

Heterogeneity within a population enhances its long-term survival. A fundamental method of maintaining population heterogeneity is the retention of rare or uncommon phenotypes by selective mating strategies. Employing two color morphs, red tuxedo and red, of the guppy (Poecilia reticulata, Poeciliidae), this study was designed to investigate whether P. reticulata females would preferentially seek out heterogeneous groupings of males exhibiting two color morphs. Adult female guppies were exposed simultaneously to two groups of males (n=10); one comprised of only the tuxedo color morph (n=5) and the other of both color morphs (n=5). For the latter group, the ratio of males …

Perchlorate Content Of Plant Foliage Reflects A Wide Range Of Species Dependent Accumulation But Not Ozone-Induced Biosynthesis, D A. Grantz, K O. Burkey, W A. Jackson, H B. Vu, M T. Mcgrath, G Harvey

United States Air Force: Publications

Perchlorate (ClO4-) interferes with uptake of iodide in humans. Emission inventories do not explain observed distributions. Ozone (O3) is implicated in the natural origin of ClO4-, and has increased since preindustrial times. O3 produces ClO4 - in vitro from Cl -, and plant tissues contain Cl- and redox reactions.We hypothesize that O3 exposure may induce plant synthesis of ClO4-.We exposed contrasting crop species to environmentally relevant O3 concentrations. In the absence of O3 exposure, species exhibited a large range of ClO4- accumulation but there was no relationship between leaf ClO4- and O3, whether expressed as exposure or cumulative flux (dose). …

Integrins Promote Cytokinesis Through The Rsk Signaling Axis, Shomita S. Mathew, Bethsaida Nieves, Sharon Sequeira, Savitha Sambandamoorthy, Kevin Pumiglia, Melinda Larsen, Susan E. Laflamme

Biological Sciences Faculty Scholarship

Cytokinesis is the final stage in cell division. Although integrins can regulate cytokinesis, the mechanisms involved are not fully understood. In this study, we demonstrate that integrin-regulated ERK (extracellular signal-related kinase) and RSK (p90 ribosomal S6 kinase) signaling promotes successful cytokinesis. Inhibiting the activation of ERK and RSK in CHO cells by a mutation in the integrin b1 cytoplasmic tail or with pharmacological inhibitors results in the accumulation of cells with midbodies and the formation of binucleated cells. Activation of ERK and RSK signaling by the expression of constitutively active RAF1 suppresses the mutant phenotype in a RSK-dependent manner. Constitutively …

Condoms And Contradictions: Assessing Sexual Health Knowledge In Lesbian, Gay, Bisexual, Trans, And Queer Youth Labelled With Intellectual Disabilities, Ciann L. Wilson

Psychology Faculty Publications

Background: Accessible, culturally relevant data collection tools to assess the sexual health knowledge of lesbian, gay, bisexual, trans, queer and questioning (LGBTQ) young people labelled with intellectual disabilities are sparse.

Materials and Methods: Using community-based participatory research (CBPR) we piloted a variety of interactive activities designed to assess the sexual health knowledge and decision making skills of LGBTQ young people with intellectual disabilities.

Results: Posters created by youth participants suggested substantial sexual health knowledge and empowerment, while individual knowledge assessment scores indicated a range in understanding of risks and strategies to avoid pregnancy, HIV and herpes.

Conclusions: These findings reinforce …

Investigating The Effect Of The ‘‘Land Between The Lakes’’ On Storm Patterns, Joshua D. Durkee, Ahmed M. Degu, Faisal Hossain, Rezaul Mahmood, Jesse Winchester, Themis Chronis

High Plains Regional Climate Center: Staff Publications

The artificially created region around the ‘‘Land between the Lakes’’ (LBL) in Kentucky represents unique land use and land cover (LULC) heterogeneities. Over a distance of 100 km, the LULC comprises artificially created open water bodies (i.e., two parallel large run-on-river dams separated by the LBL), mountainous terrain, forest cover, and extensive agricultural land. Such heterogeneities increase (decrease) moisture supply and sensible heat, resulting in a differential air mass boundary that helps to initiate (inhibit) convection. Hence, the LBL can potentially modify precipitation formation. Historical anecdotes reveal a tendency for storms to dissipate or reintensify near the LBL. The specific …

Relationship Of Follicle Size And Concentrations Of Estradiol Among Cows Exhibiting Or Not Exhibiting Estrus During A Fixed-Time Ai Protocol, G. A. Perry, O. L. Swanson, E. L. Larimore, B. L. Perry, G. D. Djira, R. A. Cushman

Roman L. Hruska U.S. Meat Animal Research Center: Reports

Cows exhibiting estrus near fixed-time artificial insemination (AI) had greater pregnancy success than cows not showing estrus. The objective of this study was to determine the relationship between follicle size and peak estradiol concentration between cows that did or did not exhibit estrus during a fixed-time AI protocol. Ovulation was synchronized in beef cows by applying the CO-Synch protocol [GnRH (100 mg) on day-9, prostaglandin F2a (PGF_2α; 25 mg) on day-2, and a second injection of GnRH 48 h after PGF_2α (day 0)] to both suckled (experiment 1) and nonsuckled (experiment 2) cows. Follicle size (day 0) …

No. 67: Migrant Entrepreneurship, Collective Violence And Xenophobia In South Africa, Jonathan Crush, Sujata Ramachandran

Southern African Migration Programme

The remarkable growth of informal migrant entrepreneurship in South Africa since 1990 would have been much lauded had it not been for the striking detail that the actors in question are seen as “foreigners” or “outsiders”. As such, they are uniformly viewed as undesirable and disadvantaging poor South African citizens. The growing presence of migrants in the informal sector has created various tensions in South Africa, including in government circles, ignoring the fact that in the free market economy of South Africa, immigrants and refugees, like citizens and commercial enterprises, would otherwise enjoy the freedom to establish, operate and expand …

No. 66: Xenophobic Violence In South Africa: Denialism, Minimalism, Realism, Jonathan Crush, Sujata Ramachandran

Southern African Migration Programme

Violent xenophobia has become a regular feature of South African life. Everyday animosity frequently spills over into violence against individual migrants and refugees and their economic enterprises. Some of these incidents reach the scrutiny of the media and officialdom, but most remain invisible and unremarked. The fact that most of the violence occurs in marginal urban locations of informal settlements, townships and inner-city suburbs in South Africa has prompted intense debate over the nomenclature and identification of the underlying causes. Explanations for the large-scale anti-migrant violence that swept the country in May 2008, and continues in more isolated and sporadic …

Quality And Safety Of Minimally Invasive Surgery: Past, Present, And Future, Bernadette Mccrory, Chad A. Lagrange, M. S. Hallbeck

Department of Mechanical and Materials Engineering: Faculty Publications

Adverse events because of medical errors are a leading cause of death in the United States (US) exceeding the mortality rates of motor vehicle accidents, breast cancer, and AIDS. Improvements can and should be made to reduce the rates of preventable surgical errors because they account for nearly half of all adverse events within hospitals. Although minimally invasive surgery (MIS) has proven patient benefits such as reduced postoperative pain and hospital stay, its operative environment imposes substantial physical and cognitive strain on the surgeon increasing the risk of error. To mitigate errors and protect patients, a multidisciplinary approach is needed …

Measurement Of Hydrodynamic Force Generation By Swimming Dolphins Using Bubble Dpiv, Frank E. Fish, Paul Legac, Terrie M. Williams, Timothy Wei

Department of Mechanical and Materials Engineering: Faculty Publications

Attempts to measure the propulsive forces produced by swimming dolphins have been limited. Previous uses of computational hydrodynamic models and gliding experiments have provided estimates of thrust production by dolphins, but these were indirect tests that relied on various assumptions. The thrust produced by two actively swimming bottlenose dolphins (Tursiops truncatus) was directly measured using digital particle image velocimetry (DPIV). For dolphins swimming in a large outdoor pool, the DPIV method used illuminated microbubbles that were generated in a narrow sheet from a finely porous hose and a compressed air source. The movement of the bubbles was tracked …

Natural And Lesion-Induced Decrease In Cell Proliferation In The Medial Nucleus Of The Trapezoid Body During Hearing Development, Aminat Saliu, Shana Adise, Sandy Xian, Kamila Kudelska, Adrián Rodríguez-Contreras

Publications and Research

The functional interactions between neurons and glial cells that are important for nervous system function are presumably established during development from the activity of progenitor cells. In this study we examined proliferation of progenitor cells in the medial nucleus of the trapezoid body (MNTB) located in the rat auditory brainstem. We performed DNA synthesis labeling experiments to demonstrate changes in cell proliferation activity during postnatal stages of development. An increase in cell proliferation correlated with MNTB growth and the presence of S100β-positive astrocytes among MNTB neurons. In additional experiments we analyzed the fate of newly born cells. At perinatal ages, …

Causality In La Mort Le Roi Artu: Free Will, Accident, And Moral Failure, David S. King

Quidditas

The thirteenth-century French La Mort le Roi Artu indicates forthrightly how the Arthurian world comes to an end, but the text leaves less clear what motivates the disaster. Many critics attribute the cause to an external force, God or the goddess Fortune, that obliges Arthur and others to pursue their own destruction. A few offer greater insight into the nature of causality in the romance. They see the characters as exercising some degree of free will or even complete liberty. But these critics err in alienating the notion of free choice from moral concerns. In their reading, the heroes suffer …

The Intersection Of Music Philosophy, Performance And Genre In The Middle English Breton Lay Sir Orfeo, Lisa Myers

Quidditas

The Middle English romance Sir Orfeo is a dynamic and creative retelling of the classical Orpheus myth in which the wife of the English king, Orfeo, is abducted by fairies but eventually restored to her position and husband through Orfeo’s musical prowess. While any retelling of the Orpheus myth would necessarily contain references to music and would, therefore, likely use music as an important cue within the text, the poet of Sir Orfeo displays a sophisticated understanding of musical philosophy, composition and performance, as well as the Breton lay genre. The intersection of these elements all work together not only …

The Impacts Of The Railways In Scotland, Isabella Katherine Stryker

Master of Liberal Studies Theses

An Anthropocene Without Archaeology—Should We Care?, Todd J. Braje, Jon M. Erlandson, C. Melvin Aikens, Tim Beach, Scott Fitzpatrick, Sara Gonzalez, Douglas J. Kennett, Patrick V. Kirch, Gyoung-Ah Lee, Kent G. Lightfoot, Sarah B. Mcclure, Lee M. Panich, Torben C. Rick, Anna C. Roosevelt, Tsim D. Schneider, Bruce Smith, Melinda A. Zeder

Faculty Publications

For more than a decade, a movement has been gathering steam among geoscientists to designate an Anthropocene Epoch and formally recognize that we have entered a new geological age in which Earth’s systems are dominated by humans. Chemists, climatologists, and other scientists have entered the discussion, and there is a growing consensus that we are living in the Anthropocene. Nobel Prize-winning atmospheric chemist Paul Crutzen (2002a, 2002b; Crutzen and Stoermer 2000) coined the term, but the idea that humans are a driver of our planet’s climate and ecosystems has much deeper roots. Italian geologist Antonio Stoppani wrote of the “anthropozoic …

Untangling Intra- And Interspecific Effects On Body Size Clines Reveals Divergent Processes Structuring Convergent Patterns In Anolis Lizards, Martha M. Muñoz, Johanna E. Wegener, Adam C. Algar

Biological Sciences Faculty Publications

Bergmann’s rule—the tendency for body size to increase in colder environments—remains controversial today, despite 150 years of research. Considerable debate has revolved around whether the rule applies within or among species. However, this debate has generally not considered that clade-level relationships are caused by both intra- and interspecific effects. In this article, we implement a novel approach that allows for the separation of intra- and interspecific components of trait-environment relationships. We apply this approach to body size clines in two Caribbean clades of Anolis lizards and discover that their similar body size gradients are constructed in very different ways. We …

Is It Time To Rethink Cord Management When Resuscitation Is Needed?, Judith S. Mercer, Debra A. Erickson-Owens

College of Nursing Faculty Publications

A newborn who receives a placental transfusion at birth, either from cord milking or delayed cord clamping, obtains about 30% more blood volume than the newborn whose cord is cut immediately. Receiving an adequate blood volume from placental transfusion at birth may be protective for the distressed neonate as it prevents hypovolemia and can support optimal perfusion to all organs. New research shows that ventilating before clamping the umbilical cord can reduce large swings in cardiovascular function and help to stabilize the newborn. Hypovolemia, often associated with nuchal cord or shoulder dystocia, may lead to an inflammatory cascade and subsequent …

Infantile Exposure To Lead And Late-Age Cognitive Decline: Relevance To Ad, Syed Waseem Bihaqi, Azadeh Bahmani, Gehad M. Subaiea, Nasser H. Zawia

Biomedical and Pharmaceutical Sciences Faculty Publications

Background: Early-life lead (Pb) exposure induces overexpression of the amyloid beta precursor protein and its amyloid beta product in older rats and primates. We exposed rodents to Pb during different life span periods and examined cognitive function in old age and its impact on biomarkers associated with Alzheimer's disease (AD).

Methods: Morris, Y, and the elevated plus mazes were used. Western blot, quantitative polymerase chain reaction (qPCR), and enzyme-linked immunosorbent assay were used to study the levels of AD biomarkers.

Results: Cognitive impairment was observed in mice exposed as infants but not as adults. Overexpression of AD-related genes (amyloid beta …

Multifaceted Nutritional Intervention In Hemodialysis Patients, Zulfitri Azuan Mat Daud

Wayne State University Dissertations

Mortality rate in patients undergoing chronic hemodialysis (HD) in the United States remain unacceptably high despite improvement in dialysis technology. Cardiovascular disease (CVD) account for more than 50% of the premature death in this population. Evidences indicate that the accelerated CVD are attributed to by malnutrition, inflammation, dyslipidemia and oxidative stress. Dietary intervention using nutrients with antioxidant, anti-inflammatory, and potential lipid altering properties to correct the aforementioned problems remain inconclusive. Furthermore, such nutritional intervention trial is often hampered by poor compliance related to medical and socioeconomic barriers. Therefore, a series of randomized, double-blind, placebo-controlled, parallel trials were undertaken to document …
