From Population Sources To Sieves: The Matrix Alters Host-Parasitoid Source-Sink Structure, James T. Cronin

Faculty Publications

Field experiments that examine the impact of immigration, emigration, or landscape structure (e.g., the composition of the matrix) on the source-sink dynamics of fragmented populations are scarce. Here, planthoppers (Prokelisia crocea) and egg parasitoids (Anagrus columbi) were released among host-plant patches that varied in structural (caged, isolated, or in a network of other patches) and functional (mudflat matrix that impedes dispersal vs. brome-grass matrix that facilitates dispersal) connectivity. Planthoppers and parasitoids on caged patches exhibited density-dependent growth rates, achieved high equilibrium densities, and rarely went extinct. Therefore, experimental cordgrass patches were classified as population sources. Because access to immigrants did …

Two's Company, Three's A Crowd: Stable Family And Threesome Roommates Problems, Chien-Chung Huang

Computer Science Technical Reports

We investigate Knuth's eleventh open question on stable matchings. In the stable family problem, sets of women, men, and dogs are given, all of whom state their preferences among the other two groups. The goal is to organize them into family units, so that no three of them have the incentive to desert their assigned family members to form a new family. A similar problem, called the threesome roommates problem, assumes that a group of persons, each with their preferences among the combinations of two others, are to be partitioned into triples. Similarly, the goal is to make sure that …

Exclusion And Object Tracking In A Network Of Processes, Yih-Kuen Tsay, Chien-Chung Huang

Computer Science Technical Reports

This paper concerns two fundamental problems in distributed computing---mutual exclusion and mobile object tracking. For a variant of the mutual exclusion problem where the network topology is taken into account, all existing distributed solutions make use of tokens. It turns out that these token-based solutions for mutual exclusion can also be adapted for object tracking, as the token behaves very much like a mobile object. To handle objects with replication, we go further to consider the more general $k$-exclusion problem which has not been as well studied in a network setting. A strong fairness property for $k$-exclusion requires that a …

An Examination Of Colliding Galaxy Clusters: Recreating 1e 0657-56 With Gadget-2, Joseph Johnson

All Theses

In this thesis I use the publicly available smooth particle hydrodynamics (SPH) code GADGET-2 to investigate and recreate the phenomenon of two merging galaxy clusters, as currently seen in the hot X-ray cluster 1E 0657-56 (the 'bullet cluster'). In this scenario, the stellar and dark matter components of the galaxies pass through the collision without experiencing strong stopping forces, but the intra-cluster gas is significantly slowed by ram pressure. This leads to a spatial separation between the galaxies and the intra-cluster gas, which provides a testing ground for gravitational theories. Weak gravitational lensing in the cluster has been used to …

Using Non-Fiction Conventions To Improve Expository Reading In 6* Grade History, Annie Whitlock

Masters Theses

Students often have very little experience with textbooks before they reach the middle and upper grades. Teachers of content areas in these grades also have very little resources available to help these students. In this study, a curriculum was developed to teach specific non-fiction conventions to 6th grade students in a history classroom. The purpose of the study was to test the hypothesis that this developed curriculum would positively impact these students’ abilities to use non-fiction conventions while reading their textbook. The results of the study revealed that after being taught the developed curriculum, the students made improvements and showed …

A Comparison Of A Scorecard Systems To Determine Supplier Efficency, Santosh Noone

Theses and Dissertations

The new trends of global competition, heightened customer expectations, and harsh economic conditions suggest that future competitiveness will be determined by a company's ability to develop strategies to optimally align and manage an extended network of supplier relationships. To remain in competition every company needs to attract and retain high-caliber suppliers. To accomplish this, firms must accurately evaluate vendor performance and must work with their suppliers to improve areas of weakness.

Scorecards are the matrix system that is used by most companies today to evaluate their supply base. These matrix systems evaluate the suppliers based on various performance factors and …

An Examination Of The Variables Affecting Rfid Tag Readability In A Conveyer Belt Environment, Jay A. Singh, C. Deupser, Eric Olsen, S. P. Singh

Industrial Technology and Packaging

There is a growing list of companies implementing radio frequency identification (RFID) systems to help optimize their supply chain processes. These companies realize that a successful RFID system can potentially lead to lower supply chain inventory levels, reduced operating expenses, and greater visibility throughout the supply chain. However, since RFID technology is still relatively immature, a majority of the applications experience less than perfect read rates for tagged items moving through the supply chain. This paper reports the results for a variety of different arrangements of variables that may influence the readability of the RFID tags in a conveyer belt …

Systematic Study Of The Validity Of Clinical Performance Assessments In Entry-Level Athletic Training Education, Gayle A. Thompson

Dissertations

PPerformance assessment (PA) is essential to determining the competency of clinical skills in allied health education, yet little research has been conducted to determine what validity evidence supports the interpretations made from PA currently utilized in athletic training clinical education. This study examined current PA practice and associated effectiveness of PA used by athletic training clinical practicum course instructors. Current research suggests the most predominant method of PA utilized in athletic training follows a behavioral approach that emphasizes observation of specific skills in standardized ways, as exemplified by the 'check-list' method. An alternative to the behavioral approach is the holistic …

Fluxes Of Iron And Manganese Across The Sediment-Water Interface Under Various Redox Conditions, Svetlana V. Pakhomova, Per O.J. Hall, Mikhail Yu Kononets, Alexander G. Rozanov, Anders Tengberg, Andrei V. Vershinin

Faculty Publications

Fluxes of dissolved forms of iron and manganese across the sediment-water interface were studied in situ in the Gulf of Finland and the Vistula Lagoon (Baltic Sea), and in the Golubaya Bay (Black Sea) from 2001 to 2005. Fluxes were measured using chamber incubations, and sediment cores were collected and sliced to assess the porewater and solid phase metal distribution at different depths. Measured and calculated benthic fluxes of manganese and iron were directed out of sediment for all sites and were found to vary between 70-4450 and 5-1000 μmole m- 2 day- 1 for manganese and iron, respectively. The …

Polymer Microfluidic Chips With Integrated Waveguides For Reading Microarrays, Feng Xu, Proyag Datta, Hong Wang, Sitanshu Gurung, Masahiko Hashimoto, Suying Wei, Jost Goettert, Robin L. Mccarley, Steven A. Soper

Faculty Publications

A microfluidic chip with an integrated planar waveguide was fabricated in poly(methyl methacrylate), PMMA, using a single-step, double-sided hot-embossing approach. The waveguide was embedded in air on three sides, the solution being interrogated on the fourth. DNA probes were covalently attached to the waveguide surface by plasma activating the PMMA and the use of carbodiimide coupling chemistry. Successful hybridization events were read using evanescent excitation monitored by an imaging microscope, which offered high spatial resolution (2 μm) and a large field-of-view (20 mm diameter field-of-view), providing imaging of the entire array without scanning. The application of the microfluidic/waveguide assembly was …

English And French Speakers' Perception Of Voicing Distinctions In Non-Native Lateral Consonant Syllable Onsets, Catherine T. Best, Pierre A. Hallé, Jennifer Pardo

Department of Psychology Faculty Scholarship and Creative Works

English and French listeners were tested on discrimination and open-response categorization of laryngeal contrasts in three non-native syllable onsets differing in gestural complexity, in particular in the phasing between laryngeal and supra-laryngeal articulations. All onsets involved a lateral, which was combined with a coronal stop in two contrasts. Results support the view that syllable onsets are perceived as holistic articulatory patterns, in which voicing is more difficult to perceive separately as gestural complexity of the onset increases.

The Effects Of Feedback On The Accuracy Of Completing Flight Checklists, William G. Rantz

Masters Theses

This study examined whether pilots completed airplane checklists more accurately when they received post-flight graphic and verbal feedback. Participants were 8 college student pilots with instrument rating. The task consisted of flying flight patterns using a Personal Computer Aviation Training Device. The main dependent variable was the number of checklist items completed correctly per flight. A multiple baseline design across pairs with reversal was used. During baseline, the average number of correctly completed items per flight varied considerably across participants, ranging from 21 to 39 out of 40. It increased to near perfect levels for all participants after they were …

Sharing Tacit Knowledge Among Expert Teaching Professors And Mentees: Considerations For Career And Technical Education Teacher Educators, Han Sik Shim, Gene L. Roth

Journal of STEM Teacher Education

This case study provides viewpoints of knowledge sharing by expert teaching professors and their mentees. Professors who were recognized as expert teachers with an annual award at a mid-western USA university were the units of analysis of this study. Expert teaching professors had difficulty articulating much of their teaching expertise. The difficulty was rooted in three characteristics of teaching expertise. Sharing tacit knowledge was also noted as a difficult task because the nature of tacit knowledge prevented it from being articulated. Methods of sharing tacit knowledge were categorized in two ways: observation and “bringing it to surface.” Recommendations for additional …

A Computer Model Of Gluconeogenesis And Lipid Metabolism In The Perfused Liver, Elie Chalhoub, Richard W. Hanson, Joanne M. Belovich

Chemical & Biomedical Engineering Faculty Publications

A mathematical model of the perfused rat liver was developed to predict intermediate metabolite concentrations and fluxes in response to changes in various substrate concentrations in the perfusion medium. The model simulates gluconeogenesis in the liver perfused separately with lactate and pyruvate and the combination of these substrates with fatty acids (oleate). The model consists of key reactions representing gluconeogenesis, glycolysis, fatty acid metabolism, tricarboxylic acid cycle, oxidative phosphorylation, and ketogenesis. Michaelis-Menten-type kinetic expressions, with control by ATP/ADP, are used for many of the reactions. For key regulated reactions (fructose-1,6-bisphosphatase, phosphofructokinase, pyruvate carboxylase, pyruvate dehydrogenase complex, and pyruvate kinase), rate …

Species Invasion Shifts The Importance Of Predator Dependence, Blaine D. Griffen, David G. Delaney

Faculty Publications

The strength of interference between foraging individuals can influence per capita consumption rates, with important consequences for predator and prey populations and system stability. Here we demonstrate how the replacement of a previously established invader, the predatory crab Carcinus maenas, by the recently invading predatory crab Hemigrapsus sanguineus shifts predation from a species that experiences strong predator interference (strong predator dependence) to one that experiences weak predator interference (weak predator dependence). We demonstrate using field experiments that differences in the strength of predator dependence persist for these species both when they forage on a single focal prey species only (the …
