Plant Community Response To Disturbances In Nebraska Sandhills Upland Prairie, Josiah D. Dallmann

Department of Agronomy and Horticulture: Dissertations, Theses, and Student Research

Historically, disturbances shaped prairie ecosystems both directly through events like fire and soil moving by animals, as well as indirectly through dynamic rainfall patterns and periodic flux in seed availabilities. We hypothesized that the implementation of several distinct disturbance events in Nebraska Sandhills upland prairie would have measurable effects on plant community composition. We implemented mid-spring fire, soil disturbance in the form of disking, seed addition of native forbs on disked plots, as well as early summer supplemental watering (to mimic minor rainfall events during abnormally dry periods) during 2016 and 2017. Plant community response during the first and second …

Promoting Preschoolers’ Emotional Competence Through Prosocial Tv And Mobile App Use, Eric Rasmussen, Gabrielle Strouse, Malinda Colwell, Collen Russo Johnson, Steven Holiday, Kristen Brady, Israel Flores, Georgene Troseth, Holly Wright, Rebecca Densley, Mary Norman

School of Education Faculty Publications

This study explored the relationship between preschoolers’ exposure to Daniel Tiger’s Neighborhood television programming and its accompanying mobile app and preschoolers’ emotion knowledge and use of emotion regulation strategies. An experiment involving 121 parent-child dyads from 3 US metro areas found that children who played with the Daniel Tiger’s Neighborhood app, and those who both played with the app and watched episodes of the program, employed the emotion regulation strategies taught by Daniel Tiger’s Neighborhood media more frequently 1 month later than children in a control condition. Preschoolers (3- and 4-year-olds) also exhibited higher levels of emotion knowledge 1 month …

Colonization Of And Adaptation To Tidal Marshes In The Savannah Sparrow (Passerculus Sandwichensis), Phred M. Benham

Graduate Student Theses, Dissertations, & Professional Papers

Intraspecific patterns of geographic variation reflect a dynamic history of colonization and divergence in response to spatially varying selective pressures. Analysis of this phenotypic variation has long stimulated biological thought, yet many outstanding questions remain regarding the ecological and evolutionary mechanisms driving patterns of geographic variation. In my dissertation, I collected data on demographic history, physiological traits contributing to salinity tolerance, and acclimation responses to different salinities to elucidate the mechanisms shaping colonization and adaptive divergence in tidal marsh populations of Savannah Sparrows (Passerculus sandwichensis). Specifically, I addressed two main questions related to adaptive divergence in this species: (1) how …

Home Is Where The Food Is: Causes And Consequences Of Partial Migration In Elk, Kristin Jennifer Barker

Graduate Student Theses, Dissertations, & Professional Papers

Migratory and non-migratory ungulates often coexist in partially migratory populations, but the mechanisms that drive and maintain different migratory behaviors within the same herd are poorly understood. In western North America, increasing numbers of elk (Cervus canadensis) reside on low-elevation winter range year-round. These residents can cause issues associated with crop damage, potential for disease transmission to livestock, and reduced effectiveness of harvest management strategies. Because migrants transfer nutrients, alter carnivore distributions, and structure vegetative communities across seasonal ranges, reductions in migratory behavior raise ecological as well as management-related concerns. This work investigated the factors affecting migratory behavior …

A Cartographic Workflow Manual For Endangered Species Conservation, Martin P. Viereckl

Graduate Student Theses, Dissertations, & Professional Papers

In response to global consumer demand for rare and exotic wildlife products, poaching of endangered species has become pervasive around the world (Eliason 1999). Despite the enactment of CITES, and other international efforts to protect vulnerable species from overexploitation, the global market for illegal wildlife products is estimated as high as $20-billion a year industry (Wyler 2008). Within important wildlife habitat sites, law enforcement struggle to curb rampant poaching that threatens the ultimate survival of many endangered species (Jachmann 2008; Rowcliffe 2004). Law-enforcement agencies responsible for protecting wildlife from poachers often lack geospatial tools that could greatly improve the effectiveness …

Midwifery Anatomized: Vesalius, Dissection, And Reproductive Authority In Early Modern Italy, Jennifer Kosmin

Faculty Journal Articles

Although Vesalius, like his contemporaries, had only extremely limited opportunities to examine or dissect the human gravid uterus, it is the image of the anatomist laying bare the (un)pregnant female body and revealing its secrets that graces the title page of the 1543 edition of De humani corporis fabrica. This essay focuses on the implications of Vesalius’s and his followers’ anatomical discoveries for the practice and professional status of early modern Italian midwives. In particular, the essay focuses on three venues in which the authority to understand the female body and the processes of reproduction were contested. A close …

Comparison Of Artificial Saliva Vs Saline Solution On Rate Of Suture Degradation In Oropharyngeal Surgery, Jenna W. Briddell, Luke Riexinger, Jove Graham, Donna M. Ebenstein

Faculty Journal Articles

IMPORTANCE Absorbable sutures are designed to degrade and lose strength over time. Manufacturers warn that exposure to various body fluids can change the estimated degradation rate of these sutures, but few studies have been conducted to quantify the degree of change associated with saliva.

OBJECTIVE To quantify the association of increased loss of strength of sutures over time after exposure to artificial saliva (hereinafter referred to as “saliva”).

DESIGN, SETTING, AND PARTICIPANTS This experimental in vitro study was conducted at Bucknell University (Lewisburg, Pennsylvania) from June 19, 2015, to July 4, 2015. No participants were involved. The loss of strength …

Branch Mathematics and Statistics Faculty and Staff Publications

In this paper, we give an outline of an ongoing study to go beyond Freudian mental archetypal model. First, we discuss the essence of numerous problems that we suffer in our sophisticated and modernized society. Then we discuss possibility to reintroduce spirit into human consciousness. While we are aware that much remain to be done and we admit that this is only a sketch, we hope that this paper will start a fresh approach of research towards more realistic nonlinear consciousness model with wide ranging implications to socio-economic modeling and also integrative cancer therapy. At the last section we also …

A Dynamic Ocean Management Tool To Reduce Bycatch And Support Sustainable Fisheries, Elliot L. Hazen, Kylie L. Scales, Sara M. Maxwell, Dana K. Briscoe, Heather Welch, Steven J. Bograd, Helen Bailey, Scott R. Benson, Tomo Eguchi, Heidi Dewar

Biological Sciences Faculty Publications

Seafood is anessential sourceofprotein formore than3billionpeopleworldwide, yet bycatchof threatened species in capture fisheries remains a major impediment to fisheries sustainability. Management measures designed to reduce bycatch often result in significant economic losses and even fisheries closures. Static spatial management approaches can also be rendered ineffective by environmental variability and climate change, as productive habitats shift and introduce new interactions between human activities and protected species. We introduce a new multispecies and dynamic approach that uses daily satellite data to track ocean features and aligns scales of management, species movement, and fisheries. To accomplish this, we create species distribution models for …

Spectators, Sponsors, Or World Travelers? Engaging With Personal Narratives Of Others Through The Afghan Women's Writing Project, Bethany Mannon

English Faculty Publications

This article studies the Afghan Women’s Writing Project and proposes three conceptual tools for examining the ways readers and editors of digital storytelling projects interact with writers and texts. The author advances discussions of personal narrative and the role this form of writing plays in transnational feminism and forms of humanitarian activism that increasingly take place online. Digital storytelling projects effectively circulate these personal accounts, but they benefit from scholarship that advises self-critical approaches to representing their subjects.

Dialogical Numbers: Counting Humanimal Pain In J.M. Coetzee's Elizabeth Costello, Mike Piero

English Faculty Publications

This essay argues that J.M. Coetzee's Elizabeth Costello stages numerical sequences strategically, dialogically, and parodically in order to call attention to the ideological weight involved in counting. Focusing on how one counts - and accounts for - human and nonhuman animal pain, I contend that the repetition of numbers in the novel works to subvert the neoliberal faith put in numbers, quantification, and data. Without succumbing to some religious-mystical numerology, this reading attempts to expose the fiction involved in the act of counting and the need to pay more attention to numerical discourse in literary fiction. In tracking these numbers …

The Mechanisms Shaping The Repertoire Of Cd4(+)Foxp3(+) Regulatory T Cells, Piotr Kraj, Leszek Ignatowicz

Biological Sciences Faculty Publications

Regulatory T (Treg) cells expressing Foxp3 transcription factor control homeostasis of the immune system, antigenic responses to commensal and pathogenic microbiota, and immune responses to self and tumour antigens. The Treg cells differentiate in the thymus, along with conventional CD4⁺ T cells, in processes of positive and negative selection. Another class of Treg cells is generated in peripheral tissues by inducing Foxp3 expression in conventional CD4⁺ T cells in response to antigenic stimulation. Both thymic and peripheral generation of Treg cells depends on recognition of peptide/MHC ligands by the T-cell receptors (TCR) expressed on thymic Treg precursors or …

Characterizing Habitat Suitability For A Central‐Place Forager In A Dynamic Marine Environment, Dana K. Briscoe, Sabrina Fossette, Kylie L. Scales, Elliott L. Hazen, Steven J. Bograd, Sara M. Maxwell, Elizabeth A. Mchuon, Patrick W. Robibson, Carey Kuhn, Daniel P. Costa, Larry B. Crowder, Rebecca L. Lewison

Biological Sciences Faculty Publications

Characterizing habitat suitability for a marine predator requires an understanding of the environmental heterogeneity and variability over the range in which a population moves during a particular life cycle. Female California sea lions (Zalophus californianus) are central‐place foragers and are particularly constrained while provisioning their young. During this time, habitat selection is a function of prey availability and proximity to the rookery, which has important implications for reproductive and population success. We explore how lactating females may select habitat and respond to environmental variability over broad spatial and temporal scales within the California Current System. We combine near‐real‐time …

Quotidian Intimidation And Mussolini's Special Tribunal In Istria And The Eastern Borderlands, Maura Hametz

History Faculty Publications

The article examines the Special Tribunal for the Defense of the State's use of the "no grounds to proceed" ruling to intimidate anti-fascists and extend the fascist government's power in the Adriatic borderlands. It demonstrates how the Tribunal's judges used their sentencing prerogatives to support repression in Istria and cloak persecution in the mantel of legal action in defense of the state.

Plastid Dna Variation Of The Endemic Species Oxytropis Glandulosa Turcz. (Fabaceae), Alla Kholina, Marina Kozyrenko, Elena Artyukova, Denis Sandanov, Inessa Selyutina, Daba Chimitov

Turkish Journal of Botany

Oxytropis glandulosa Turcz. (Fabaceae) is a rare perennial plant endemic to Buryatia (Russia). We sequenced three intergenic spacers (the psbA−trnH, trnL−trnF, and trnS−trnG) of chloroplast DNA (cpDNA) in specimens of four populations from two geographic regions (Barguzin and Yeravna depressions) within this species range. The levels of haplotype and nucleotide diversity varied in the range of 0.133−0.911 and 0.0002−0.0059, respectively. The highest values of these parameters are characteristic of populations located in the Barguzin depression. Variable sites detected within the intergenic spacers allowed the identification of eleven haplotypes; nine of them were found in the populations from the Barguzin depression …

Predicting The Potential Distribution Area Of Solidago Xniederederi (Asteraceae), Malgorzata Jazwa, Elzbieta Jedrzejczak, Ewelina Klichowska, Artur Pliszko

Turkish Journal of Botany

In this study, we aimed to investigate the potential distribution area of Solidago xniederederi, a natural hybrid between North American S. canadensis and European S. virgaurea, in Central and East Europe using the MAXENT modeling approach. The final MAXENT model was constructed based on 83 occurrence records from Austria, Poland, Lithuania, and Latvia and six abiotic environmental variables. The jackknife test revealed that annual temperature range, mean temperature of wettest quarter, and minimum temperature of coldest month had the highest gain for the training and test data when used alone, whereas precipitation seasonality, precipitation of coldest quarter, and precipitation of …

Players In A Storm: Climate And Political Migrants In The Tempest And Othello, Darcie Rees

Master's Theses and Doctoral Dissertations

This paper presents a reading of migrants and their relationships with political and environmental slow violence in William Shakespeare’s The Tempest and Othello. Using Steve Mentz’s work with water and shipwreck, Lowell Duckert’s work on water in Shakespeare, Rob Nixon’s concept “slow violence,” Patricia Fumerton’s book on vagrancy in sixteenth and seventeenth century England, and Ken Hiltner’s work with environmental advocacy of the same time, I read the social history of vagrancy of the time (presented by Hiltner and Fumerton) alongside the Poor Laws. This social history is combined with water-focused ecocriticism, shipwreck and a postcolonial reading of migrancy. Ultimately, …

Irrational Science Breeds Irrational Law, Caleb Small

Emory Law Journal

Current jurisprudence regarding the subject matter eligibility requirement for patents relies upon outdated assumptions in both philosophy of science and the scientific endeavor itself. In relying upon these assumptions, the Supreme Court, especially in its recent decisions covering biotechnology and computer software, has given the arguably more technocratic lower federal court judges a confusing and unworkable test. Scholars have proposed new approaches on subject matter eligibility, urging courts to revisit and revitalize other areas of the patentability analysis: utility and the written description requirement. While these arguments adeptly characterize some solutions to the current predicament, they do so without utilizing …

Enforcing An Unenforceable Law: The National Bioengineered Food Disclosure Standard, Mary Christine Brady

Emory Law Journal

Congress hastily crafted the National Bioengineered Food Disclosure Standard (¿GE labeling law¿ or Act), which it passed in July of 2016, to preempt various state laws that were cropping up around the country seeking to label genetically engineered ingredients (GEs). This Comment anticipates that the Act will face free speech challenges that may find the GE labeling law unconstitutional, especially following recent trends in First Amendment jurisprudence that have been increasingly applying stricter scrutiny upon constitutional review. Due to inconsistent applications of the two governing tests that review compelled commercial speech¿the Central Hudson and Zauderer standards, respectively¿this Comment suggests that …

Persona¿Character Copyrights And Merger¿S Role In The Evolution Of Entertainment Expressions, Sydney Altman

Emory Law Journal

This Comment defines what qualifies as a character and what makes the character eligible or ineligible for copyright protection. This Comment proposes placing characters on a spectrum, from those that are granted full copyright protection to those that are denied legal security. When the line is not clear regarding whether a character is an original expression or is a persona of the actor, this Comment suggests utilizing the merger doctrine as a personal affirmative defense to eliminate a studio¿s inflexible copyright control and to release the character into the actor¿s shared control.

Bioethics & Vulnerability: Recasting The Objects Of Ethical Concern, Michael Thomson

Emory Law Journal

Mainstream bioethics has long been challenged for its focus on the technological developments of biomedicine and principles of individual ethics. It is argued that the focus on these particular objects, and the delisting of the social context within which the ethical is constructed and experienced, limits the extent to which bioethics provides a contesting counter-weight to modern biomedicine. In response, this Article promotes Martha Fineman¿s vulnerability theory as a new framework for bioethical deliberation. Fineman¿s foundational concern with the embodied and embedded experience of being human puts the social at the heart of analytical enquiry. Further, a focus on the …

Disturbance Of Redox Homeostasis In Down Syndrome: Role Of Iron Dysmetabolism, Eugenio Barone, Andrea Arena, Elizabeth Head, D. Allan Butterfield, Marzia Perluigi

Sanders-Brown Center on Aging Faculty Publications

Down syndrome (DS) is the most common genetic form of intellectual disability that leads in the majority of cases to development of early-onset Alzheimer-like dementia (AD). The neuropathology of DS has several common features with AD including alteration of redox homeostasis, mitochondrial deficits, and inflammation among others. Interestingly, some of the genes encoded by chromosome 21 are responsible of increased oxidative stress (OS) conditions that are further exacerbated by decreased antioxidant defense. Previous studies from our groups showed that accumulation of oxidative damage is an early event in DS neurodegeneration and that oxidative modifications of selected proteins affects the integrity …

Expatriation Restored, Jonathan David Shaub

Law Faculty Scholarly Articles

Expatriation - the loss or relinquishment of citizenship - has a long and divisive history as a fundamental concept of American citizenship. It has been the subject of contentious and robust debate from the very beginning of the country. This Article posits that the concept of expatriation today has little jurisprudential salience, despite its increasing rhetorical valence in the context of terrorism, because the historical development of the concept has obscured its meaning. Expatriation originally had a precise meaning: an individual right declared by the country in 1868 to be "indispensable" to the inalienable rights identified in the Declaration of …

Registration Is Fundamental, Brian L. Frye, Nicole E. Pottinger

Law Faculty Scholarly Articles

Under the Copyright Act, copyright owners can file infringement actions only if registration of their copyright claim with the Copyright Office “has been made” or “has been refused.” The United States Supreme Court recently granted certiorari in Fourth Estate v. Wall-Street.com, in order to decide whether registration is “made” when a claimant files a registration application or when the Copyright Office registers the claim.

This article argues that the Court should hold that registration occurs when the Copyright Office registers the claim, in order to ensure that federal courts can benefit from the expertise of the Copyright Office. The Copyright …
