At The Intersection Of Gender And Race: A Qualitative Study Of The Lived Experiences Of African American Female Elementary Principals, Andrea M. Haynes

Student Work

This study examined the “lived experiences” related to race, gender, and the construct of time for five African American female elementary principals. The study specifically explored the intersectionality of race and gender. Through a qualitative phenomenological framework, the study aimed to research the implications of race and gender, at a specific point in time, for African American females in the elementary principalship. A phenomenological research method, that included semi-structured interviews, was employed to capture the essence of the participants’ stories and to fully understand their common experiences. Critical Race theory and Feminism theory were used as an intersecting lens for …

Assessing Genetic Variation Of Rocky Mountain Bighorn Sheep At Elk Mountain, Brynn L. Parr, Rebeca L. Juarez, Jonathan A. Jenks

The Prairie Naturalist

The bighorn sheep (Ovis canadensis canadensis) herd occupying the Elk Mountain Region of South Dakota and Wyoming was established in 2001 with 20 individuals. An additional 7 ewes were released in 2004. The population increased to approximately 120 individuals in 2009, but subsequently declined to an estimated 80 individuals. Because of the low population size used to establish the herd and relative isolation of the Elk Mountain Region, potential factors associated with the population decline included reduced genetic diversity. Our objectives were to: 1) assess genetic diversity, 2) measure effective population size (Ne), and 3) compare the genetic diversity of …

Keys To Lichens Of North America, Revised And Expand- Ed. Irwin M. Brodo (Photographs By Sylvia Duran Sharnoff And Stephen Sharnoff; Drawings By Susan Laurie-Bourque)., Caleb A. Morse

The Prairie Naturalist

It would be hard to overestimate the importance of the 2001 publication of Lichens of North America (hereafter LNA) by Irwin Brodo, Silvia Duran Sharnoff, and Stephen Sharnoff (Brodo et al. 2001). Beautifully illustrated, LNA included both an excellent overview to lichenology—including such diverse topics as chemistry, ecology, ethnolichenology, and specimen preparation—and descriptions of more than 800 of the common and charismatic lichens of North Ameri- ca. It is the rare book that provides a good introduction to the discipline, while serving as an essential tool for lichenologists. LNA is frequently cited in journals as an authoritative source on spot …

Varmints And Victims: Predator Control In The Ameri- Can West. Frank Van Nuys., Phil Mastrangelo

The Prairie Naturalist

Having recently retired after 30+ years working in the field of human-wildlife conflicts, including predator conflicts with livestock, I looked forward to reading Varmints and Victims: Predator Control in the American West by Frank Van Nuys. As a wildlife biologist with an interest in the history of wildlife management in North America, I was further intrigued by the subject matter selected by Van Nuys.

In the book’s introduction, Van Nuys explains how the issue of mountain lion (Puma concolor) management in his home state of South Dakota sparked his interest in further exploring the history of predators and their management …

Why We Had To Leave; A Study Of Human Rights & Refugees (9th-12th Grade), Marisa C. Cavin

Understanding by Design: Complete Collection

This unit was designed around 9th grade accelerated learners in a World Geography classroom at an international school. Prior to this unit, we connected national boundary changes and economic power shifts in Europe, the Middle East, and Central Asia to decolonization and WWII. The goal of this unit is to humanize the “refugee” and to understand the far-reaching and immediate causes and consequences of mass migrations in the modern world in geo-politically significant regions. To accomplish this, the unit prepares students to understand how the world defines human rights and the ways these “rights” are protected or, in the case …

The Adoption And Use Of The Hirschman–Herfindahl Index In Nonprofit Research: Does Revenue Diversification Measurement Matter?, Grace L. Chikoto, Qianhua Ling, Daniel G. Neely

Accounting Faculty Research and Publications

Since its introduction by Tuckman and Chang, the Hirschman–Herfindahl Index (HHI) has been widely adopted into the nonprofit literature as a precise measure of revenue concentration. This widespread adoption has been characterized by diverse composition, with the HHI’s calculation being largely determined by the nature of the available data and the degree to which it contained disaggregated measures of revenue. Using the NCCS 990 Digitized Data, we perform an acid test on whether different HHI measures yield significantly different results. Four measures of revenue concentration—an aggregated measure based on three revenue streams, an aggregated measure separating government grants from other …

Aristotle And The Cynics On Happiness And Misfortune, Christopher Turner

College of Liberal Arts & Social Sciences Theses and Dissertations

The fundamental concern of ancient ethics is the question concerning happiness. As Aristotle famously poses it in EN I, that everyone is concerned with happiness is given but as to what it is there is much dispute. My dissertation project takes up the question of happiness and considers its relation to fortune, and in particular, misfortune, as it is treated in both Aristotle and his contemporaries, the ancient Cynics. It is my thesis that fortune has a problematic status in relation to happiness in Aristotle’s ethical and political thought: Aristotle’s consideration of Solon’s dictum ‘Look to the end’ in NE …

A Comparison Of Catabolic Pathways Induced In Primary Macrophages By Pristine Single Walled Carbon Nanotubes And Pristine Graphene, Caroline More, Jennifer Mcintyre, Luke O'Neill, Hugh Byrne

Articles

Understanding the correlation between the physico-chemical properties of carbonaceous nanomaterials and how these properties impact on cells and subcelluar mechanisms is critical to their risk assessment and safe translation into newly engineered devices. Here the toxicity, uptake and catabolic response of primary human macrophages to pristine graphene (PG) and pristine single walled carbon nanotubes (pSWCNT) are explored, compared and contrasted. The nanomaterial toxicity was assessed using three complementary techniques (live-dead assay, real time impedance technique and confocal microscopic analysis), all of which indicated no signs of acute cytotoxicity in response to PG or pSWCNT. Transmission electron microscopy (TEM) demonstrated that …

Grandiose Narcissism Predicts Willingness To Behave Badly, Without Proportional Tolerance For Others’ Bad Behavior, Harry M. Wallace, Benjamin R M Scheiner, Andrew Grotzinger

Psychology Faculty Research

Narcissists characteristically behave badly; our study investigated how they respond to experiencing others’ bad behavior. After completing the Narcissistic Personality Inventory, a measure of grandiose narcissism, participants reported their willingness to engage in different inconsiderate or unethical common behaviors. Then they reported how bothered they would feel in response to experiencing each of the same bad behaviors—perpetrated by someone else. Participants overall reported feeling bothered by others’ bad behavior, but narcissism was unrelated to intolerance judgments. Narcissists are often highly reactive when their inflated self-views are challenged, but our study suggests that narcissists are not uniquely bothered by everyday minor …

Pure Partial Awareness Or Interaction Between The Mask And The Masked Stimuli?, Jiangong Guo, Jerwen Jou, Qian Cui, Guang Zhao, Shen Tu

Psychological Science Faculty Publications

Many studies using masking paradigm have shown that stimuli can be processed unconsciously. However, different researchers put forward different ideas about the mechanisms of the unconscious information processing. For example, one idea is that the unconscious information might be derived from a partial awareness of the masked stimulus. Another idea is that it is derived from a perceptual interaction between a masked stimulus and the masking stimulus. We used a masking paradigm (with a briefly displayed target followed by a mask) and a subjective rating and an objective forced-choice test (with a word and picture version) given after the display …

Modification Of The In Vitro Uptake Mechanism And Anti-Oxidant Levels In Hacat Cells And Resultant Changes To Toxicity And Oxidative Stress Of G4 And G6 Poly (Amido Amine) Dendrimer Nanoparticles., Marcus Maher, Hugh Byrne

Articles

The mechanism of cellular uptake by endocytosis and subsequent oxidative stress has been identified as the paradigm for the toxic response of cationically surface charged nanoparticles. In an attempt to circumvent the process, the effect of increased cellular membrane permeability on the uptake mechanisms of poly (amidoamine) dendrimers generation 4 (G4) and 6 (G6) in vitro was investigated. Immortalised, non-cancerous human keratinocyte (HaCaT) cells were treated with DL-Buthionine-(S,R)-sulfoximine (BSO). Active uptake of the particles was monitored using fluorescence microscopy to identify and quantify endosomal activity and resultant oxidative stress, manifest as increased levels of reactive oxygen species, monitored using the …

Screening The Low Molecular Weight Fraction Of Human Serum Using Atr-Ir Spectroscopy, Franck Bonnier, Matthew J. Baker, Hugh Byrne

Articles

Vibrational spectroscopic techniques can detect small variations in molecular content, linked with disease, showing promise for screening and early diagnosis. Biological fluids, particularly blood serum, are potentially valuable for diagnosis purposes. The so-called Low Molecular Weight Fraction (LMWF) contains the associated peptidome and metabolome and has been identified as potentially the most relevant molecular population for disease-associated biomarker research. Although vibrational spectroscopy can deliver a specific chemical fingerprint of the samples, the High Molecular Weight Fraction (HMWF), composed of the most abundant serum proteins, strongly dominates the response and ultimately makes the detection of minor spectral variations a challenging task. …

Bathymetric Survey For Lakes Azuei And Enriquillo, Hispaniola, Michael Piasecki, Mahrokh Moknatian, Fred Moshary, Joseph Cleto, Yolanda Leon, Jorge Gonzalez, Daniel Comarazamy

Publications and Research

The two largest lakes on the Caribbean Island of Hispaniola, Lake Azuei in Haiti and Lake Enriquillo in the Dominican Republic, have experienced dramatic growth and surface area expansion over the past few years leading to severe flooding and loss of arable land around the lake perimeters. In order to better understand the reasons for this unprecedented rate of expansion and the resulting consequences a multi-disciplinary team comprised of researchers from Haiti, the DR, and the US have embarked on an extensive data collecting and hydrologic and climatological modeling campaign. While the sensor deployment entails stations that measure climatological data …

"A Medium For Meeting God": C.S. Lewis And Music (Especially Wagner), John Macinnis

Faculty Work Comprehensive List

This essay will survey Lewis’s writings and outline the development of his aesthetic ideas in relation to music, emphasizing his enjoyment of Wagner and explaining nuanced references to Wagner throughout Lewis’s works. Moreover, this essay will describe how Lewis’s ideas about God advanced in counterpoint to his ideas about music and how Lewis came to eventually conclude that music is a medium for meeting God. To conclude, I share ways in which Lewis’s ideas have influenced and strengthened my own teaching of Wagner in Music History and Literature classes.

Exploring The Possibility Of Photosynthetic Plasticity In Agave Sensu Lato, John Anthony Huber

Theses and Dissertations

Crassulacean acid metabolism (CAM) provides desert plants with distinct advantages over the C₃ and C₄ photosynthetic pathways in harsh climates where water is scarce. CAM is, however more metabolically costly than C₃ or C₄ photosynthesis, and some plants, such as Mesembryanthemum crystallinum, facultatively utilize CAM when water is abundant, and water conservation unnecessary. In such situations, these plants behave akin to a C₃ plant when photosynthesizing. CAM is divided into four phases, with each phase displaying unique metabolic processes. Certain changes, including changes in the timing of CO₂ fixation, stable carbon isotope ratios, …

Prosthetic Leg Kit For Deployment In Developing Countries, Brian Murphy, Dominique Porcincula, Derek Morgan, Kendall Ruggles, Christian Aguayo

Biomedical Engineering

The World Health Organization estimates that over 30 million people require some sort of prosthetic technology. However, traditional prosthetic fitting practices take a lot of time and cost a lot of money, making them inaccessible to millions of people around the world. StandUP Worldwide is an interdisciplinary project team devoted to creating low-cost prosthetic technologies for use around the world, especially in resource poor areas. They are currently developing a low cost, below-the-knee prosthetic kit that can be easily deployed in a resource-poor area. The following presents their solution for a below-the-knee prosthetic socket, foot, and leg.

OES Faculty Publications

Continental shelves and shelf seas play a central role in the global carbon cycle. However, their importance with respect to trace element and isotope (TEI) inputs to ocean basins is less well understood. Here, we present major findings on shelf TEI biogeochemistry from the GEOTRACES programme as well as a proof of concept for a new method to estimate shelf TEI fluxes. The case studies focus on advances in our understanding of TEI cycling in the Arctic, transformations within a major river estuary (Amazon), shelf sediment micronutrient fluxes and basin-scale estimates of submarine groundwater discharge. The proposed shelf flux tracer …

Loma Linda University Electronic Theses, Dissertations & Projects

The purpose of this clinical investigation was to evaluate and compare the degree of new bone formation through histomorphometric analysis following maxillary sinus grafts (MSG) using three different bone graft materials. Thirty-one MSG were performed using a lateral window approach for patients who required implant placement in posterior maxilla. Each sinus was randomly selected to receive one of three bone graft materials; Group A: anorganic bovine bone mineral (ABBM) [Bio-Oss®], Group B: anorganic equine bone mineral (AEBM) [Equimatrix®], or Group C: mineralized cancellous bone allograft (MCBA) [OSSIF-i sem™]. A total of 28 bone cores were obtained at a mean time …

The Growth And Ecology Of Upper Cambrian Microbialite Biostromes From The Notch Peak Formation In Utah, Ken P. Coulson

Loma Linda University Electronic Theses, Dissertations & Projects

Exposure of carbonate rocks within the uplifted mountains of southwestern Utah presents a unique opportunity to study the growth, morphology and ecology of two upper Cambrian microbialite reefs located within the Hellnmaria Member of the Notch Peak Formation. The first reef contains meter-length, strongly elongate microbialites that grew in a deep, subtidal marine environment. These elongate microbialites formed as a result of coalescence of round ‘algal’ heads, a process known to produce compound microbialite structures in shallow water, but seldom explored as a key factor in the elongation of deep, subtidal forms that grew in ancient environments. The second reef …

Strategies For Protecting Privacy In Open Data And Proactive Disclosure, Teresa Scassa, Amy Conroy

Canadian Journal of Law and Technology

In this paper, the authors explore strategies for balancing privacy with transparency in the release of government data and information as part of the growing global open government movement. The issue is important because government data or information may take many forms, may contain many different types of personal information, and may be released in a range of contexts. The legal framework is complex: personal information is typically not released as open data or under access to information regimes; nevertheless, in some cases transparency requirements take precedence over the protection of personal information. The open courts principle, for example, places …

The Role Of Bed Shear Stress In Sediment Sorting Patterns In A Reconstructed, Gravel Bed River, Samuel Emerson

Master's Theses

The role of bed shear stress in bed surface grain size sorting was investigated on a reconstructed reach of the Merced River in the Central Valley of California. Pebble count data were collected at the inside, middle, and outside of ten bends in April 2015 and compared to data from pebble counts conducted in previous years. Output from a previously developed 2D flow model (FaSTMECH) was compared to critical shear stresses calculated from median grain-size data. Comparison of pebble count results from 2002 through 2015 showed that there was no temporally consistent pattern of coarsening or fining along the study …
