Bat Activity Over Wetlands: Temporal And Spatial Variation, Sarah Stankavich

EWU Masters Thesis Collection

"Foraging animals face decisions about when and where to forage based, in part, on prey availability, which can fluctuate temporally as well as spatially. For temperate insectivorous bats, wetlands are important forage habitats because they provide water and high abundances of insects. My overall objective was to identify abiotic and biotic factors that influence bat foraging activity over wetlands in the channeled scablands of eastern Washington. I surveyed 12 wetland sites at Turnbull National Wildlife Refuge (TNWR) in Cheney, Washington, 3 or 4 times during summer 2012. Ten stations were set up at each site to measure insect abundance using …

Exploitation Of The Bacteriophage-Derived Peptidase Chapk, Pierre-Mehdi Hadbi

Theses

This project investigated an anti-staphylococcal bacteriophage-derived peptidoglycan hydrolase enzyme, namely a cysteine-histidine amydohydrolase/peptidase (CHAP_k). The study focused firstly on optimizing the production of recombinant CHAP_k, which was previously cloned in an E. coli expression system, and sets out the resulting optimal Standard Operating Procedures (SOPs) for production, purification and determination of concentration and activity of the resulting protein stock. A typical yield resulting from the investigation was 300pg of CHAP_k from one litre of E.coli culture. The activity of the purified enzyme was typically in the region of 190U nmol ’. Secondly, the project investigated …

Spatial And Seasonal Variation In The Stable Isotopic Composition Of Thirteen-Lined Ground Squirrel Fecal Pellets As An Estimate Of Variation In Diet, Allie Chacko

Honors Theses

We performed stable isotope analyses of fecal pellets to investigate temporal and spatial patterns in the diet of free-ranging, thirteen-lined ground squirrels (Ictidomys tridecemlineatus). Samples were collected opportunistically from a population in SW Michigan from May to September 2012. We found a statistically significant increases in d13C values throughout the study period, possibly correlating to a late-season flush of C-4 plants. Also, samples collected within 25 m of a cornfield had a mean d13C value of -20.470%, a value significantly higher than those outside the 25 m border (mean=26.192%). This patternmay be indicative of a C-4 rich diet probably due …

Hawksbill Turtle Eretmochelys Imbricata Nesting Environment And Population Study In Cuero Y Salado Wildlife Refuge On The Coast Of Northern Honduras, Ariana Emily Cunningham

Honors Theses

This report outlines my contributions to ProTECTOR's Hawksbill turtle conservation project along the beachfront at Cuero y Salado Wildlife Refuge of Honduras. Observation-focused nightly beach patrols were conducted so as to census numbers of turtles nesting in this location presently and beach characteristic surveys were undertaken to create a map of environmental factors relevant to Hawksbill nesting along this beach. Resulting environmental maps were correlated with known factors contributing to Hawksbill nest site choice in order to assess the suitability of this beach for Hawksbill nesting, and thus determine its value for preservation efforts and ongoing funding. Of the 10 …

The Prevalence Of Encysted Toxoplasma & Sarcocystis In Consumer-Grade Pork, Beef, And Lamb In Michiana, Ross Trecartin

Honors Theses

Commonly present in the muscle of animals are the tissue cysts of Toxoplasma and Sarcocystis. The aim of this study was to determine the presence and levels of Toxoplasma/Sarcocystis tissue cysts in retail pork, beef, and mutton throughout the Michiana area. A total of 36 samples from the three species of interest were exposed to a digestive solution mimicking stomach conditions. The solution consisted of 0.75% pepsin, 0.86% NaCl, and HCl adjusted to a pH of 1-2. The digested samples were then strained through several layers of cheesecloth, centrifuged, and examined for the presence of parasites. Toxoplasma/Sarcocystis were detected in …

Effect Of Latrunculin B On Phonotaxis In Induced Selective Crickets Treated With Jhiii (Acheta Domesticus), Jerome Martin

Honors Theses

The purpose of this experiment is to determine the effect of the actin kinase inhibitor, latrunculin B, on previously unselective crickets. We expected the injecion of a mixture of latrunculin B and juvenile hormones (JHIII) into the prothoracic ganglion would cause a reduction in the affect of JHIII in older crickets, causing them to remain unselective. Based on the results we can conclude that latrunculin B reduces the effect of JHIII, which indicates that creating new synapses is at least a partial effect of JHIII.

Variation In The Calling Song Of The Cricket Gryllus Pennsylvanicus Across Geographic Longitudinal Change, Ioana Danci

Honors Theses

Variation of cricket calling songs can be attributed to environmental factors, including temperature, humidity, vegetation, season, solar elevation, and geographic location. Recent studies found that latitudinal position affects the calling song of male Gryllus pennsylvanicus. My project evaluates whether longitudinal position influences the calling song of G. pennsylvanicus. Using the predicted values of 4 song features based on a mathematical model (Burden 2009), I evaluated data from 6 locatons along a longitudinal axis. I calculated R2 values to determine how well the model predicted the values in my sample populations. The model was found to be a poor predictor.

Spatial And Seasonal Signals In Stable Isotopes Of Incisor Enamel From Free-Ranging, Thirteen-Lined Ground Squirrels, Jacob Andrew Brassington

Honors Theses

From early May through late September, 2012, we captured, tagged, and collected body masses from multiple, free-ranging thirteen-lined ground squirrels (Ictidomys tridecemlineatus) in southwestern Michigan, with 14 individuals recaptured 1 or more times through the season. Beginning in mid-June, we captured and euthanized 12 or these individuals (on average, about 1 per week) to allow study of their lower incisors. We serially micro-sampled enamel along squirrel incisors using laser ablation and determined stable isotope ratios (d13 and d18 O) with gas chromatography-isotope-ratio mass spectrometry (GC-IRMS). The resulting values fell into two spatial groups. Specimens collected within 25 m of a …

Verdi At 200: Recent Scholarship On The Composer And His Works, Linda B. Fairtile

University Libraries Faculty and Staff Publications

The 100th anniversary of Verdi’s death, observed in 2001, inspired nearly a dozen academic conferences. At the dawn of his 2013 bicentennial, a celebratory year shared with Richard Wagner, hundreds of recent studies assess Verdi’s life, his works, and his impact. The present article surveys a selection of books and articles published between these two commemorations. A popular topic is Verdi’s role as a national icon, the calculated product of Italy’s search for a postunification identity. His engagement with foreign cultures has also received attention, for his German literary sources, his forays into French grand opera, and his use of …

Predation, Turbidity, And Other Factors Influencing Juvenile Salmonid Survival In The Lower Snake River, Devin M. Sontag

EWU Masters Thesis Collection

"The object of this study was to quantify consumption rates of juvenile salmonids by three introduced species, smallmouth bass (Micropterus dolomieu), walleye (Sander vitreus) and channel catfish (Ictalurus punctatus). Consumption information is crucial because the construction of the Snake River hydrosystem has created a series of reservoirs, which have altered the river 's flow regimes, riparian vegetation, and turbidity. Further, several non-native fishes have been introduced as sport fish into the Lower Snake River. This combination of physical alterations and new biological interactions with introduced species has reduced the survival of anadromous salmonids in the Lower Snake River. Currently all …

Detection And Characterization Of Antibiotic Resistance Plasmids In Cheney Biosolids, Gaayathiri Paramasivam

EWU Masters Thesis Collection

"Biosolids are organic matter produced at the end of sewage treatment process. It has been shown that during sewage treatment, resistant bacteria are selected because of the presence of antibiotics and their byproducts. These resistant bacteria are more likely to transfer resistance genes to other bacteria. In the current study, we examined Cheney biosolids for the presence of drug resistant bacteria and the role of these bacteria in transfer of resistance genes to others. We screened 100 bacteria for drug resistance and found that 68% of the isolates were resistant to two or more drugs tested. Plasmids were separated from …

Historical Remedies Versus Current Pathogens : Laboratory Investigation Of The Efficacy Of Traditional Herbal Remedies Against Present-Day Common Causes Of Bacterial Pneumonia, Eibhlin Mccarthy

Theses

Despite the medical advances of recent years, pneumonia is still a common disease in Ireland, accounting for approximately 7% of deaths in this country'. While national databases such as those run by CIDR and SARI ensure that incidences of systemic and notifiable infections such as tuberculosis are recorded, there are currently no available statistics on commonplace respiratory isolates within Ireland. This study analysed the available data on bacterial pathogens isolated from respiratory samples at a 355 bed Irish hospital over a one year period. Seasonal variations and resistance patterns were noted. The most frequently isolated pathogens were Staphylococcus aureus (27%), …

Evaluating Hypotheses That Explain Non-Continuous Responses To Syllable Periods ("Skipping") During Phonotaxis By Female Acheta Domesticus, Tori Joy Steely

Master's Theses

One way to classify female cricket phonotactic response is as "non-skipping" or "skipping." "Skipping" is defined as crickets that respond to a non-continuous range of calling songs. This investigation evaluates the temporal aspects of typical phonotactic protocols and attempts to determine if "skipping" is due to a filtering mechanism or if "skipping" is an artifact of testing protocol. Rather than a notch filter or testing parameters inhibiting a phonotactic response to a syllable period within the range of a band pass filter, I hypothesize that "skipping" occurs as a result of the probabilistic nature of phonotaxis.

Features Of Copulation And The Copulation Call In Glaucous-Winged Gulls (Larus Glaucescens), Amanda Sandler

Master's Theses

Glaucous-winged gulls (Larus glaucescens) breed along the Pacific Northwest coast where they perform highly stereotypical behavior patterns, including associated vocalizations. Early studies suggested the copulation call functions in maintaining pair bonds. Recent studies, however, challenge the idea that strengthening pair bonds is the only function of this call. I described the spectral and temporal features of the copulation call and investigated whether copulation behaviors varied over the course of the 2012 nesting season. During continuous observations from a blind in daylight hours, I documented the start and stop time for every copulation in a sample area of a nesting colony …

Balancing Human And Machine Contributions In Human Computation Systems, R. Jordan Crouser, Alvitta Ottley, Remco Chang

Computer Science: Faculty Publications

Many interesting and successful human computation systems leverage the complementary computational strengths of both humans and machines to solve these problems. In this chapter, we examine Human Computation as a type of Human-Computer Collaboration—collaboration involving at least one human and at least one computational agent. We discuss recent advances in the open area of function allocation, and explore how to balance the contributions of humans and machines in computational systems. We then explore how human-computer collaborative strategies can be used to solve problems that are difficult or computationally infeasible for computers or humans alone.

Financial Retrenchment And Institutional Entrenchment: Will Legal Education Respond, Explode, Or Just Wait It Out?, Ian Weinstein

Faculty Scholarship

Both markets and ideas have turned against the American legal profession. Legal hiring has contracted, and law school enrollments are decreasing. The business models of big law and legal education are under pressure, current levels of student indebtedness seem unsustainable, and a hero has yet to emerge from our fragmented regulatory structures. In the realm of ideas, the information revolution has sparked deep critiques of structured knowledge and expertise, opening the roles of the law and the university in society to reexamination. We are less enamored of the scholar-lawyer and gaze with longing at technocrats. I hope that clinical law …

International Law In A Time Of Scarcity: An Introduction, Harlan G. Cohen

Faculty Scholarship

Stories of scarcity litter the morning newspapers. Around the world, resources — food, water, fuel sources, clean air — seem stretched to, or even beyond, capacity. Consequences have already been serious, including suffering and unrest. Competition for resources seems likely only to increase. Does international law have the tools to manage or even solve this growing global problem? It was with this question in mind that the editors of the Georgia Journal of International and Comparative Law convened their 2012 symposium: “International Law in a Time of Scarcity.”

This short essay serves as introduction to that symposium and the related …

Combination Thermochemotherapy For The Treatment Of Non-Muscle Invasive Bladder Cancer, Ramy Said Goueli

Yale Medicine Thesis Digital Library

Bladder cancer is the fourth most commonly diagnosed malignancy and is the eighth leading cause of cancer death among men in the United States of America. Furthermore, it is the seventh and seventeenth most common cancer among males and females, respectively with increasing incidence among Caucasian compared with other ethnicities. Thus it is of utmost importance to develop strategies to improve our ability to early diagnose as well improve treatments by developing new drugs or develop novel treatments. We hypothesized that improving drug potency by enhancing their uptake into tumors will improve their clinical efficacy and enhance tumor killing. We …

A Presence Of The Past: The Legal Protection Of Singapore’S Archaeological Heritage, Jack Tsen-Ta Lee

Research Collection Yong Pung How School Of Law

Singapore is not well known for its archaeological heritage. In fact, chance finds in the early 20th century and systematic archaeological excavations since the 1980s conducted at sites around the Singapore River have unearthed artefacts shedding light on the island’s early history. In addition, the value of archaeology for a deeper knowledge of Singapore’s British colonial past is increasingly being recognized. Nonetheless, Singapore law provides only a rudimentary framework to facilitate archaeological investigations and protect cultural artefacts. This article considers how the National Heritage Board Act (Cap 196A, 1994 Rev Ed), the Planning Act (Cap 232, 1998 Rev Ed), and …

Embodied Conflict Resolution: Resurrecting Roleplay-Based Curricula Through Dance, Nadja Alexander, Michelle Lebaron

Research Collection Yong Pung How School Of Law

Moving on from the authors’ seminal 2009 critique of the overuse of role-plays in negotiation teaching, "Death of the Role-Play" (chapter 13 in Rethinking Negotiation Teaching), Alexander and LeBaron have taken the rapidly increasing enthusiasm for experiential learning in a new direction: multiple intelligences. Their particular interest is in a use of experiential learning that focuses on kinesthetic intelligence, employing actual physical movement, particularly dance, to unlock creativity in other mental domains, as well as to encourage authentic participation by people whose skills are not primarily verbal or mathematical. Those who may be inclined to be skeptical should note that …

Assessing Connections Between Young Children’S Affinity For Nature And Their Experiences In Natural Outdoor Settings In Preschools, Camilla S. Rice, Julia C. Torquati

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

The purposes of this research were to: develop a reliable measure of children’s affinity for nature or “biophilia”; determine whether young children’s biophilia was related to the “green-ness” of the outdoor play area of the preschool they attend; examine whether demographic variables are associated with children’s biophilia; and determine whether demographic variables predict children’s enrollment in nature-oriented programs. We recruited children from ten early childhood education programs—six that had outdoor play spaces with many natural elements and four that had few or none of these elements. One hundred fourteen preschool-aged children completed an 11-item measure of biophilia that included preferences …

Beyond The Walls: Conceptualizing Natural Environments As “Third Educators”, Julia C. Torquati, Julie A. Ernst

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

This research examined preservice early childhood educators’ perceptions of outdoor settings and their intentions to use outdoor settings in their teaching practice. Students enrolled in an early childhood education program (n = 110) at a university in the Great Lakes region completed surveys that assessed perceptions of natural settings, intentions to use natural settings in future teaching, knowledge of the benefits of nature for children, and personal nature relatedness. Participants reported relatively high intentions to use natural settings in future teaching, as well as knowledge of the benefits of nature for children, but moderate levels of personal nature relatedness. Participants …
