Attachment And Biofilm Formation Of Foodborne Pathogens, Sara Jean Smith

Microbiological Sciences

Outbreaks of Listeria monocytogenes, Salmonella, and Escherichia coli are increasingly attributed to fresh produce. Current control measures have been assessed for decades, with no alternatives adopted. Sources were identified, reducing flhD transcription and biofilm amounts nearly 2-fold. β-phenylethylamine (PEA), reduced growth and biofilm 96% and 70%, respectively. Curli production was assessed and found to be microorganism-, strain-, and/or serotype-dependent. Reporter fusions were constructed, evaluating expression of Listeria cellulose protein (Lcp). Plcp was not impacted by conditions used. Conditions were then used in attachment of L. monocytogenes to stainless steel. Attachment was significantly reduced by 5 ppm chlorine and 2% lysate. …

North Dakota Wetlands: Changes Over Five Years In Prairie Pothole Wetlands And A Description Of Vegetative And Soil Properties In A North Dakota Fen, Kristine Mary Altrichter

Natural Resources Management

Wetlands provide ecosystem services such as water quality, flood attenuation, primary productivity, biodiversity, and provide habitats for wildlife. Land use conversions from natural to agricultural and urban landscapes threaten the quantity and quality of wetlands globally. Monitoring remaining wetlands has become increasingly important as degradation persists, particularly in agriculturally productive regions like the Prairie Pothole Region (PPR) of North Dakota. Two studies were completed in the summers of 2016 and 2017 to contribute to efforts to monitor wetlands in North Dakota. The first study aimed to assess the overall condition of prairie pothole wetlands across North Dakota using the North …

Dynamic Modelling For The Path Tracking Control Of A Four-Wheel Independent-Drive, Four-Wheel Independent-Steer Autonomous Ground Vehicle, Karl Klindworth

Mechanical Engineering and Applied Mechanics

Robots that can be reconfigured to perform more than one task would be to consumers. The Four-Wheel Independent-Drive, Four-Wheel Independent-Steer (4WD4WS) robot is well suited for the role of reconfigurable robot due to its extremely high maneuverability and torque control. However, the nonlinear dynamics in conjunction with complex kinematic constraints make the 4WD4WS structure an extremely difficult control problem. As a result of this many who model the 4WD4WS structure make simplifications that aren’t realistic for a reconfigurable consumer robot. A 4WD4WS robot is kinematically and dynamically modeled using both the front and rear path angles and their respective coordinates. …

16s Ribosomal Rna And Phylograms: Characterizing Student Reasoning To Learning Outcomes From The American Society For Microbiology Curriculum, Chelsey Lee Grassie

Microbiological Sciences

The American Society for Microbiology (ASM) has established a suggested curriculum for introductory microbiology courses that includes a focus on evolution. However, no data is published to describe how proficiently students address the learning outcomes, in part because validated assessments do not exist. Thus, the goal of this project was to develop assessment prompts that capture student understanding about fundamental statement five under the core concept of evolution. In total, 167 written responses were collected from upper-division microbiology courses, with pre-pharmacy and microbiology majors comprising the majority of students (74.6%). Two coders coded all written responses, and five student interviews …

Obama's Conversion On Same-Sex Marriage, Robert Tsai

Scholarly Articles in Law Reviews & Journals

This essay explores how presidents who wish to seize a leadership role over the development of rights must tend to the social foundations of those rights. Broad cultural changes alone do not guarantee success, nor do they dictate the substance of constitutional ideas. Rather, presidential aides must actively re-characterize the social conditions in which rights are made, disseminated, and enforced. An administration must articulate a strategically plausible theory of a particular right, ensure there is cultural and institutional support for that right, and work to minimize blowback. Executive branch officials must seek to transform and popularize legal concepts while working …

Exploring The Multidimensional Structure Of The Wasi-Ii: Further Insights From Schmid-Leiman Higher-Order And Exploratory Bifactor Solutions, Brittany Mcgeehan, Nadine Ndip, Ryan J. Mcgill

Archives of Assessment Psychology

The Wechsler Abbreviated Scale of Intelligence-Second Edition (WASI-II; Wechsler, 2011a) is a versatile and widely utilized brief intelligence measure by assessment psychologists in a variety of clinical settings. Despite the fact that a hierarchical measurement model is implied in the WASI-II Manual (Wechsler, 2011b) and the scores provided by the instrument, a hierarchical measurement model was not specified in the structural validation studies conducted by the test publisher. Due to this shortcoming, two exploratory factor analytic methods (Schmid-Leiman [SL] and exploratory bifactor analysis [EBFA]) were utilized to disclose the higher-order structuring of WASI-II variables. Results from both solutions indicated that …

Job Descriptive Index (Jdi): Reliability And Validity Study In Greece, Theodosis Tasios, Vaitsa Giannouli

Tracking Radical Opinions In Polls Of U.S. Muslims, Veronika Fajmonová, Sophia Moskalenko, Clark R. Mccauley

Psychology Faculty Research and Scholarship

This Research Note examines two telephone polls (2007, 2011) and three Internet polls (2016) to track opinionsof U.S. Muslims relating to the war on terrorism. Results indicate that a small but consistent minority (five to tenpercent) justify suicide bombing of civilians in defense of Islam, while those seeing the war on terrorism as a war on Islam have declined from more than half to about a third. This decline coincided with a decline in perception of discrimination against Muslims in the U.S., and correlational results confirm that perceived discriminationis one source of seeing the war on terrorism as a war …

Effect Of Sequence Of Simulated And Clinical Practicum Learning Experiences On Clinical Competency Of Nursing Students, Jamie Hansen, Marilyn Bratt

College of Nursing Faculty Research and Publications

Two different sequences of blocks of simulated and clinical practicum learning experiences compared the clinical competency development of nursing students using a randomized crossover design. Competency was measured 3 times: after each block of simulated and clinical experiences and after a final simulated experience. No significant differences in competency scores between the 2 groups across the 3 time points were found. Using alternative models of clinical and simulation learning may help address barriers to the delivery of clinical education faced by schools of nursing

Fertility Care Services, Richard J. Fehring

College of Nursing Faculty Research and Publications

The Catholic Church calls married couples to responsible parenthood; this includes both openness to new human life and the avoidance of pregnancy when serious reasons present themselves. Natural methods of family planning respect the dignity of the person and the integrity of the sexual act. They treat fertility as a natural process rather than a disease. Natural family planning (NFP) works with a woman’s menstrual cycle; it uses awareness of fertile and infertile times to achieve or avoid pregnancy and allows married couples, through their awareness, to respect and maintain both the unitive and the procreative aspects of the sexual …

Examining The Relationship Between Clinical Judgment And Nursing Actions In Prelicensure Students, Andrea Stuedemann Fedko, Kristina Dreifuerst

College of Nursing Faculty Research and Publications

Faculty frequently use the Lasater Clinical Judgment Rubric (LCJR) to identify students’ clinical judgment; however, it is unclear whether LCJR scores relate to appropriate nursing action. In a pilot study consisting of senior-level nursing students (N = 22), participants were scored on the LCJR and anticipated nursing actions, and results were analyzed using simple linear regression. There was a statistically significant correlation (r = 0.364) between clinical judgment and nursing action. Results suggest that total LCJR scores may be an indicator of the completion of indicated nursing action.

The massification of higher education is now a global phenomenon Huge changes in the teaching and learning milieu within colleges. The forces of massification have brought multiple challenges with regard to pedagogy. What kind of pedagogy to employ? The role of the lecturer is to empower learning and it is challenging and complex. There is a need to employ a pedagogy which requires students to do things, to access information, to solve problems, to reflect on what they are doing and make connections to real world problems.

Educational research has revealed a number of important lessons for educators:

Deep Models For Engagement Assessment With Scarce Label Information, Feng Li, Guangfan Zhang, Wei Wang, Roger Xu, Tom Schnell, Jonathan Wen, Frederic Mckenzie, Jiang Li

Electrical & Computer Engineering Faculty Publications

Task engagement is defined as loadings on energetic arousal (affect), task motivation, and concentration (cognition) [1]. It is usually challenging and expensive to label cognitive state data, and traditional computational models trained with limited label information for engagement assessment do not perform well because of overfitting. In this paper, we proposed two deep models (i.e., a deep classifier and a deep autoencoder) for engagement assessment with scarce label information. We recruited 15 pilots to conduct a 4-h flight simulation from Seattle to Chicago and recorded their electroencephalograph (EEG) signals during the simulation. Experts carefully examined the EEG signals and labeled …

First Performance Results Of A New Field-Widened Spatial Heterodyne Spectrometer For Geocoronal Hα Research, D. D. Gardner, E. J. Mierkiewicz, F. L. Roesler, J. M. Harlander, K. P. Jaehnig, S. M. Nossal, L. M. Haffner

Publications

A new, high-resolution field-widened spatial heterodyne spectrometer (FW-SHS) designed to observe geocoronal Balmer α (Hα, 6563 Å) emission was installed at Pine Bluff Observatory (PBO) near Madison, Wisconsin. FW-SHS observations were compared with an already well-characterized dual-etalon Fabry-Perot Interferometer (PBO FPI) optimized for Hα, also at PBO. The FW-SHS is a robust Fourier transform instrument that combines a large throughput advantage with high spectral resolution and a relatively long spectral baseline (~10 times that of the PBO FPI) in a compact, versatile instrument with no moving parts.Coincident Hα observations by FW-SHS and PBO FPI were obtained over similar integration times, …

Anisotropic Character Of Low-Order Turbulent Flow Descriptions Through The Proper Orthogonal Decomposition, Nicholas Hamilton, Murat Tutkun, Raúl Bayoán Cal

Mechanical and Materials Engineering Faculty Publications and Presentations

Proper orthogonal decomposition (POD) is applied to distinct data sets in order to characterize the propagation of error arising from basis truncation in the description of turbulence. Experimental data from stereo particle image velocimetry measurements in a wind turbine array and direct numerical simulation data from a fully developed channel flow are used to illustrate dependence of the anisotropy tensor invariants as a function of POD modes used in low-order descriptions. In all cases, ensembles of snapshots illuminate a variety of anisotropic states of turbulence. In the near wake of a model wind turbine, the turbulence field reflects the periodic …

Increased System Fidelity For Navy Aviation Hypoxia Training, Beth. F. Wheeler Atkinson, Janet Marnane, Daniel L. Immeker, Jonathan Reeh, John Zbranek, Ashwin K. Balasubramanian, David M. Mcettrick, W. Tyler Scheeler

Publications

In 2009, the Naval Aviation Survival Training Program (NASTP) Trainer Management Team (TMT) identified a need for a next-generation normobaric mask-on hypoxia trainer with enhanced capabilities due to the lack of positive air pressure provided by existing capabilities. The lack of a positive pressure-on-demand airflow delivery for current mask-on hypoxia training has been cited as a potential training gap wherein 44% of students experience air hunger (Artino, Folga, & Vacchiano, 2009). As a result, it is unclear whether students are able to recognize more subtle symptoms of hypoxia or if they are masked by air hunger. To address this, researchers …

Background: Exercise causes an acute decrease in the pain sensitivity known as exercise-induced hypoalgesia (EIH), but the specificity to certain pain modalities remains unknown. This study aimed to compare the effect of isometric exercise on the heat and pressure pain sensitivity.

Methods: On three different days, 20 healthy young men performed two submaximal isometric knee extensions (30% maximal voluntary contraction in 3 min) and a control condition (quiet rest). Before and immediately after exercise and rest, the sensitivity to heat pain and pressure pain was assessed in randomized and counterbalanced order. Cuff pressure pain threshold (cPPT) and pain tolerance (cPTT) …

A Multi-Method Exploration Of The Genetic And Environmental Risks Contributing To Tobacco Use Behaviors In Young Adulthood, Elizabeth K. Do

Theses and Dissertations

Tobacco use remains the leading preventable cause of morbidity and mortality in both the United States and worldwide. Twin and family studies have demonstrated that both genetic and environmental factors are important contributors to tobacco use behaviors. Understanding how genes, the environment, and their interactions is critical to the development of public health interventions that focus on the reduction of tobacco related morbidity and mortality. However, few studies have examined the transition from adolescent to young adulthood – the time when many individuals are experimenting with and developing patterns of tobacco use. This dissertation thesis seeks to provide a comprehensive …

Comparisons Of Isogenic Trisomic And Disomic Cells From People With Mosaicism For Down Syndrome Unmask Cellular Differences Related To Trisomy 21, Kelly A. Rafferty

Theses and Dissertations

It is known that age-related changes impacting multiple organ systems occur earlier in people with Down syndrome (Ds), but the biological basis underlying this trisomy 21-associated propensity for premature aging is poorly understood. Given that the trisomic/normal cells from people with mosaic Ds (mDs) are identical with regards to environmental exposures and genes (except for chromosome 21 copy number), comparisons of these isogenic trisomic/disomic cells allow one to “unmask” the cellular consequences of trisomy 21 by removing extraneous factors. The primary aim of this study was to determine if trisomy 21 results in an increase in the acquisition of age-related …
