Soil Peels: Their Preparation And Presentation, Tim D. Overheu

All other publications

Soil peels are an exciting and inexpensive technique for collecting an exact reproduction of soil profiles. They are an excellent product for displays and soil extension activities. Introduced in the mid-1960s, the soil peel (lackfilm) technique was initially developed using a flexible glue product in combination with a cloth base, and was used to preserve soil stratigraphy at geo-archaeological excavations (Voight & Gittins 1977). The method described in this update introduces refinements to the technique for heavy and consolidated clay or duplex soils in Western Australia. Applying and removingtechnique was initially developed using a flexible glue product in combination with …

Against Agnosticism: Why The Liberal State Isn't Just One (Authority) Among The Many, Linda C. Mcclain

Faculty Scholarship

This article takes up the gauntlet thrown down by Professor Abner Greene’s recent book, Against Obligation: The Multiple Sources of Authority in a Liberal Democracy, to those scholars, politicians, and activists who believe that realizing the ideal of e pluribus unum (out of many, one) as well as constitutional principles of liberty and equality require a robust role for government. Government, Greene argues, is just one source of authority among many others, and citizens – or even public officials – have no general moral duty to obey the law. The political and constitutional order of the United States, he contends, …

Carnivore Use Of Avocado Orchards Across An Agricultural-Wildland Gradient, Theresa M. Nogeire, Frank W. Davis, Jennifer Duggan, Kevin R. Crooks, Erin E. Boydston

AES Faculty Publications and Presentations

Wide-ranging species cannot persist in reserves alone. Consequently, there is growing interest in the conservation value of agricultural lands that separate or buffer natural areas. The value of agricultural lands for wildlife habitat and connectivity varies as a function of the crop type and landscape context, and quantifying these differences will improve our ability to manage these lands more effectively for animals. In southern California, many species are present in avocado orchards, including mammalian carnivores. We examined occupancy of avocado orchards by mammalian carnivores across agricultural-wildland gradients in southern California with motion-activated cameras. More carnivore species were detected with cameras …

Human Leukocyte Antigens And Cellular Immune Responses To Anthrax Vaccine Adsorbed, Inna G. Ovsyannikova, V. Shane Pankratz, Robert A. Vierkant, Nicholas M. Pajewski, Conrad P. Quinn, Richard A. Kaslow, Robert M. Jacobson, Gregory A. Poland

United States Public Health Resources

Interindividual variations in vaccine-induced immune responses are in part due to host genetic polymorphisms in the human leukocyte antigen (HLA) and other gene families. This study examined associations between HLA genotypes, haplotypes, and homozygosity and protective antigen (PA)-specific cellular immune responses in healthy subjects following immunization with Anthrax Vaccine Adsorbed (AVA). While limited associations were observed between individual HLA alleles or haplotypes and variable lymphocyte proliferative (LP) responses to AVA, analyses of homozygosity supported the hypothesis of a “heterozygote advantage.” Individuals who were homozygous for any HLA locus demonstrated significantly lower PA-specific LP than subjects who were heterozygous at all …

Brief 8: International Fisheries Governance That Works: The Case For A Global Fisheries Organization, J. Samuel Barkin, Elizabeth R. Desombre

Governance and Sustainability Issue Brief Series

International fisheries are being overexploited, and the current institutional structure in place to manage them is not working effectively. Presently, two sets of intergovernmental institutions oversee global fishing. The first comprises roughly three dozen regional fisheries management organizations (RFMOs), approximately 19 of which are charged with regulating fishing in the areas they oversee. The second set consists of global organizations that touch on but do not directly regulate fisheries issues, such as the United Nations Food and Agriculture Organization (FAO), the World Trade Organization (WTO), the World Bank, and the International Maritime Organization (IMO). This management patchwork is inadequate to …

Role Of Nucleation In Cortical Microtubule Array Organization: Variations On A Theme, Erica A. Fishel, Ram Dixit

Biology Faculty Research

The interphase cortical microtubules (CMTs) of plant cells form strikingly ordered arrays in the absence of a dedicated microtubule-organizing center. Considerable research effort has focused on activities such as bundling and severing that occur after CMT nucleation and are thought to be important for generating and maintaining ordered arrays. In this review, we focus on how nucleation affects CMT array organization. The bulk of CMTs are initiated from γ-tubulin-containing nucleation complexes localized to the lateral walls of pre-existing CMTs. These CMTs grow either at an acute angle or parallel to the pre-existing CMT. Although the impact of microtubule-dependent nucleation is …

Jules Verne's Dream Machines: Technology And Transcendence, Arthur B. Evans

Global Language Studies Faculty publications

This article discusses how Verne mythologizes and poeticizes his fictional machines. More than just a means for solving problems and/or for providing access to exotic geographical locales, Verne’s technology is portrayed as being intrinsically poetic. Bridging the worlds of the industrial and the artistic, Verne’s machines constitute a new kind of objet d’art. Anthropomorphized to make them seem less coldly mechanical, these devices take on a life of their own and exist in a richly symbiotic relationship with their creators. Such machines transport the readers of Verne’s Voyages extraordinaires beyond the mimetic, serving both as a means to build verisimilitude …

Aboriginal And Non-Aboriginal Students Learn About Natural Health Products From Different Information Sources, Sarah O. Alkholy, Samiah N. Alqahtani, Audrey Cochrane, Maria Pontes Ferreira, Fidji Gendron

Nutrition and Food Science Faculty Research Publications

Natural health products (NHPs) include naturally derived botanical and nonbotanical products. Past research indicates a high prevalence of NHPs use amongst adults in the United States and Canada but does not clearly characterize NHPs use amongst students, ethnic variations of such use, or how users learn about NHPs. We hypothesize that there is a difference between Aboriginal and non-Aboriginal students in how they learn about NHPs. To investigate this question, we conducted a cross-sectional study at First Nations University of Canada and the University of Regina, Saskatchewan, Canada, during the fall of 2011. Aboriginal (n=214) and non-Aboriginal (n=749) students participated …

Proposal For An Animal Crimes Unit Within The Milwaukee Police Department, Caroline Knitter

Professional Projects

The incidence of animal abuse continues to rise in communities across this nation. The range of animal abuse crimes includes starvation and neglect, dog fighting, sexual abuse to malicious killing. Research indicates that crime against or involving animals often leads to crime against humans, interpersonal violence. Many animal abuse crimes go unreported, and the human victims involved are unidentified. Overburdened with crimes against humans, many police departments do not have the resources available to focus on animal abuse. To address this issue, animal crimes units are being initiated in police departments in some major cities. The purpose ofthis research study …

Environmental Law, Travis M. Trimble

Mercer Law Review

In 2012, the United States Court of Appeals for the Eleventh Circuit, deciding an issue of first impression, held that a party that enters a consent order to settle potential liability under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) is not entitled to pursue a cost recovery action against other potentially responsible parties under section 107 of the Act, but may only seek contribution from those parties under section 113(f) of the Act. The court also affirmed a decision by the Bureau of Ocean Energy Management to approve an exploration plan for oil and gas drilling in the …

Exploring Epigenetic Regulation Of Fear Memory And Biomarkers Associated With Post-Traumatic Stress Disorder, Stephanie A. Maddox, Glenn E. Schafe, Kerry J. Ressler

Publications and Research

This review examines recent work on epigenetic mechanisms underlying animal models of fear learning as well as its translational implications in disorders of fear regulation, such as Post-traumatic Stress Disorder (PTSD). Specifically, we will examine work outlining roles of differential histone acetylation and DNA-methylation associated with consolidation, reconsolidation, and extinction in Pavlovian fear paradigms. We then focus on the numerous studies examining the epigenetic modifications of the Brain-derived neurotrophin factor (BDNF) pathway and the extension of these findings from animal models to recent work in human clinical populations. We will also review recently published data on FKBP5 regulation of …

Does Boyer’S Integrated Scholarships Model Work On The Ground? An Adaption Of Boyer’S Model For Scholarly Professional Development, William E. Boyd

International Journal for the Scholarship of Teaching & Learning

Boyer’s model of four scholarships as an integrated system engaging and integrating the scholarships of discovery, integration, application, and teaching is being increasingly adopted both by individual scholars and institutions. Here I reflect on my own adoption of this approach almost a decade ago, and I describe one application, its use in defining my professional academic profile. While this does not directly address issues of pedagogy, it provides a sound basis for improved pedagogical practice in higher education. I assess my adoption of Boyer’s model against several benchmarks grounded in the social life of academe: success of promotion; mentoring peers …

Genomic Analysis Of Stress Response Against Arsenic In Caenorhabditis Elegans, Surasri N. Sahu, Jada Lewis, Isha Patel, Serdar Bozdag, Jeong H. Lee, Robert Sprando, Hediye Nese Cinar

Mathematics, Statistics and Computer Science Faculty Research and Publications

Arsenic, a known human carcinogen, is widely distributed around the world and found in particularly high concentrations in certain regions including Southwestern US, Eastern Europe, India, China, Taiwan and Mexico. Chronic arsenic poisoning affects millions of people worldwide and is associated with increased risk of many diseases including arthrosclerosis, diabetes and cancer. In this study, we explored genome level global responses to high and low levels of arsenic exposure in Caenorhabditis elegans using Affymetrix expression microarrays. This experimental design allows us to do microarray analysis of dose-response relationships of global gene expression patterns. High dose (0.03%) exposure caused stronger global …

Portable Game Based Instruction Of American Sign Language, Christyna Wilson

All Theses

In this thesis, we address the effectiveness of portable gaming devices as a vehicle for learning American Sign Language. We begin by creating a multi-level game using a standard programming language, and use the game to illustrate various signed words. We translate the game to mobile devices using Kivy, a crossplatform framework. This allows the game to be compatible with multiple mobile devices and platforms. A secondary inspiration for creating a game as opposed to standard memorization techniques is to stimulate a quicker learning response as the user enjoys the sign learning process. In this thesis we provide a mobile …

Improving Spoken Programming Through Language Design And The Incorporation Of Dynamic Context, Benjamin M. Gordon

Computer Science ETDs

Programming is not just about the syntax of the language; the programming environment is also an important part of the process. In English prose speech recog- nition, knowledge of the context of the conversation or document being produced is useful to disambiguate otherwise error-prone phrases or words. Our spoken programming environment explores the same idea applied to programming by incorporating several forms of context inherent in computer programs to guide and enhance the speech recognition engine: We use the structure and grammar of the language itself, we use scoping of symbols and identifiers, and we incorporate constraints gleaned from type …

Anti-Immigrant Ideology In U.S. Crime Reports: Effects On The Education Of Latino Children, Theresa Catalano

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

This article investigates the link between how Latino migrants are represented in U.S. crime reports, the formation of immigration laws/policies, and the effects on children of Latino migrants in U.S. schools. From a framework of cognitive linguistics and critical discourse analysis, I examine crime reports in U.S. online newspapers depicting crimes allegedly committed by Latino migrants in the years 2008–2010. The analysis exposes linguistic strategies such as the use of metaphor and metonymy to construct a negative representation of Latino migrants. I conclude with a discussion of the indirect effects on Latino schoolchildren.

Health and Nutritional Sciences Faculty Publications

OBJECTIVE: The present study evaluated the restaurant and dining venues on and near post-secondary campuses varying in institution size.
DESIGN: The Nutrition Environment Measures Survey for Restaurants (NEMS-R) was modified to evaluate restaurants as fast food, sit down and fast casual; and campus dining venues as dining halls, student unions and snack bar/cafe´s. ANOVA with post hoc Tukey’s B and T tests were used to distinguish differences between dining venues and associated institutions by size.
SETTING: The study was conducted at fifteen US post-secondary institutions, 2009–2011.
SUBJECTS: Data presented are from a sample of 175 restaurants and sixty-eight on-campus dining …

Translations From Allada And Experience D'Edward Lee, Versailles By Gérard Gavarry, Gérard Gavarry, Katina Rogers

Publications and Research

At the heart of Gérard Gavarry’s writing are the questions of what power language holds, and what remains beyond the reach of expression. The two translations included here, excerpts from Allada (P.O.L, 1993) and Expérience d’Edward Lee, Versailles (P.O.L, 2009), share little with each other in terms of setting or structure, but explore similar questions of the role and limits of language in relation to defamiliarization, power, and fear. The inventive reflection on the nature of language, identity, and power that, woven into the fabric of the novel, makes Gavarry’s work some of the most compelling fiction coming out of …

The Peak At The Nadir: Psychological Turmoil As The Trigger For Awakening Experiences, Steve Taylor

International Journal of Transpersonal Studies

A study of 161 temporary awakening experiences showed that over 23% were triggered by, or associated with, intense turmoil and distress (Taylor, 2012b). Examples of some of these turmoil-induced awakening experiences are given, illustrating the wide variety of traumatic experiences involved. (The type of trauma was found to be less important than its intensity.) These temporary awakening experiences are contrasted with permanent suffering-induced transformational experiences (SITEs). A distinction is made between a primary shift, involving the establishment of a new self-system (which occurs in SITEs), and the secondary shift which may occur after temporary awakening experiences, when the individual’s self-system …

Implications And Consequences Of Post-Modern Philosophy For Contemporary Transpersonal Studies Ii. Georges Bataille’S Post-Nietzschean Secular Mysticism, Phenomenology Of Ecstatic States, And Original Transpersonal Sociology, Harry Hunt

International Journal of Transpersonal Studies

The writings of the French philosopher Georges Bataille (1897-1962) offer their own contribution to the descriptive phenomenology of mystical and numinous states, as well as a version of the modern secular or this-worldly mysticism variously anticipated by Jung and Nietzsche, and a highly original sociology and social psychology of transpersonal experience, influenced by Max Weber, that helps to open an area not widely developed in recent studies. At the same time, the trauma and personal difficulties in Bataille’s life serve as a stark example of the often distortive effects of spiritual metapathologies on inner development. Bataille’s views of ecstatic states …

Intentional Kayaking: Awakening To Intimacy Within The Natural World, Nancy M. Rowe

International Journal of Transpersonal Studies

This article explores the notion of intimacy within the natural world. The author blends personal quest with scholarship from transpersonal psychology, spirituality, nature writing, and philosophy. It highlights the results of a thematic content analysis of journal entries made during a week of kayaking with the conscious intention of being in better relationship with a specific lake community. A thematic analysis of the journal entries that followed this experience revealed that that certain actions, attitudes, and ways of being increased intimacy and contributed to a greater sense of spirituality. She posits that we can all achieve greater spiritual connection and …

Understanding Relationships Among Abundance, Extirpation, And Climate At Ecoregional Scales, Erik A. Beever, Solomon Z. Dobrowski, J. Long, A. R. Mynsberge, N. B. Piekielek

Forest Management Faculty Publications

Recent research on mountain-dwelling species has illustrated changes in species' distributional patterns in response to climate change. Abundance of a species will likely provide an earlier warning indicator of change than will occupancy, yet relationships between abundance and climatic factors have received less attention. We tested whether predictors of counts of American pikas (Ochotona princeps) during surveys from the Great Basin region in 1994-1999 and 2003-2008 differed between the two periods. Additionally, we tested whether various modeled aspects of ecohydrology better predicted relative density than did average annual precipitation, and whether risk of site-wide extirpation predicted subsequent population counts of …

Measuring Bonds In Equine-Facilitated Psychotherapy, Carla K. Sloan-Brown

Master's Theses or Doctor of Nursing Practice

Equine-facilitated psychotherapy is a type of animal-assisted intervention that has potential to be an effective therapeutic modality in the treatment of psychiatric disorders. It is theorized that a meaningful relationship is formed between client and horse; this relationship is thought to inspire meaningful change in the client. The current study found evidence of human-equine bonds and determined they can be measured quantitatively using adapted bonding scales. This study also explored variables that may impact bonds formed between clients and horse co-therapists. Finally, a potential correlation between the strength of the bond and the severity of symptoms over the course of …

Temperament, Attachment, And Coparenting As Risk And Protective Factors Of Depression In Young Adulthood, Whitney Giesing

Master's Theses or Doctor of Nursing Practice

Depression is a serious mental illness that affects millions of people. Depression can cause severe life impairment and is associated with numerous life threatening risk factors. Though treatment of depression is important, prevention is ideal. Therefore, it is important to understand associated risk and protective factors of depression. Several factors may precede the development of depression in young adulthood. This study sought to better understand the role of temperament, parent-child attachment relationships, and child reported co-parenting quality on the development of depressive symptoms in young adults between the ages of 18 and 22. Previous studies have suggested that some temperament …

Undoing The Factory Model: A Practical Field Test In Blended Learning, Adam Holden

Master's Theses or Doctor of Nursing Practice

The successful implementation of e-learning strategies into the learning process is not a new idea. Education was first introduced to the concept of digital natives using technological tools to learn over a decade ago now, and yet we remain a nation struggling to come to terms with the educational potential of technology. It is true, that the past ten years has seen a significant integration of hardware into the classroom; the question must be asked however, whether this has been wastefully accomplished by many schools, without predetermined planning or the development of strategic outcomes for its use. Merely, introducing these …

Studying The Relationship Between Mud/Salt Flat Habitat And Shorebird Abundance At Two Wetland Areas Using Landsat, Dustin Reagan

Master's Theses or Doctor of Nursing Practice

The objective of this project was to determine the degree and direction of association between the amount of mud/salt flat area and shorebird abundance during spring and early summer. This study used Landsat 5 to indirectly measure mudflat and salt flat areas at two wetland complexes within Kansas over a period of several years (1991-2008). These measurements were compared to shorebird surveys conducted by several individuals at both Quivira National Wildlife Refuge and Cheyenne Bottoms Wildlife Area. A correlation analysis showed that significant relationships exist between mud/salt flat area and the abundance of certain shorebird species. Correlation coefficients for individual …
