Hyperbaric Oxygen Therapy For Alzheimer’S Dementia With Positron Emission Tomography Imaging: A Case Report, Paul G. Harch, Edward F. Fogarty

Radiology Faculty Publications

A 58-year-old female was diagnosed with Alzheimer’s dementia (AD) which was rapidly progressive in the 8 months prior to initiation of hyperbaric oxygen therapy (HBOT). 18Fluorodeoxyglucose (18FDG) positron emission tomography (PET) brain imaging demonstrated global and typical metabolic deficits in AD (posterior temporal-parietal watershed and cingulate areas). An 8-week course of HBOT reversed the patient’s symptomatic decline. Repeat PET imaging demonstrated a corresponding 6.5–38% regional and global increase in brain metabolism, including increased metabolism in the typical AD diagnostic areas of the brain. Continued HBOT in conjunction with standard pharmacotherapy maintained the patient’s symptomatic level of function over an ensuing …

Summer Therapeutic Program For Children, Randi Losalu

Social Work Independent Study Projects (ISP)

Children who struggle during the school year will continue to do so through the summer months. As such, it is important to have therapeutic opportunities and programming available for those children. Addressing the therapeutic needs of children with serious emotional disturbances and/or social deficits can take many forms. Adventure therapy and experiential activities are supported by a variety of theoretical perspectives including Experiential Learning Theory, Systems Theory, Existential Theory, Behavioral/Cognitive Behavioral Theory, and Psychodynamic Theory. Through the use of adventure type activities, participants are able to address and reach therapeutic goals in a different manner than the traditional office setting. …

A Brief Review Of Mueller Matrix Calculations Associated With Oceanic Particles, Bingqiang Sun, George W. Kattawar, Ping Yang, Xiaodong Zhang

Earth System Science and Policy Faculty Publications

The complete Stokes vector contains much more information than the radiance of light for the remote sensing of the ocean. Unlike the conventional radiance-only radiative transfer simulations, a full Mueller matrix-Stokes vector treatment provides a rigorous and correct approach for solving the transfer of radiation in a scattering medium, such as the atmosphere-ocean system. In fact, radiative transfer simulation without considering the polarization state always gives incorrect results and the extent of the errors induced depends on a particular application being considered. However, the rigorous approach that fully takes the polarization state into account requires the knowledge of the complete …

Motivations And Satisfaction Of North Dakota Deer Hunters During A Temporal Decline In Deer Populations, Kristen E. Black, William F. Jensen, Robert Newman, Jason Boulanger

Biology Faculty Publications

Achieving state wildlife agency biological goals for deer (Odocoileus spp.) management may often conflict with hunter desires. Concomitantly, better information is needed to optimize agency deer herd management goals with hunters’ social goals. In 2016, we surveyed 3,000 North Dakota, USA, resident deer hunters using a self-administered mail survey to gain a better understanding of motivations, satisfaction, and hunter demographics that may be used to inform hunter recruitment and retention (HRR) efforts during a period of reduced statewide deer populations. With deer-gun license availability strictly limited, we explored the possibility that some gun hunters may have been engaging …

Self-Determined Motivation In Foreign Language Learning: Examining The Effects On Students' Achievement, Yawo Badagbo

Theses and Dissertations

This study investigated the relationship between foreign language motivation and self-determined motivation, as well as the issue of students’ perceptions of strategies used to improve foreign language motivation and achievement among undergraduate students in the department of foreign language. This research was conducted in two mid-western universities among undergraduate foreign language learners. The participants were undergraduate foreign language learners. A total of 391 students from 18- 43 years old started the paper-and-pencil surveys in which they shared their views and perceptions about foreign language learning motivations and strategies to improve motivations and achievement. However, only 380 completed the majority of …

Some Features Of Participant Reference In Xochapa Mixtec, Laura J. Cline

Theses and Dissertations

Many works have been published about the grammar and phonology of Mixtecan languages, but relatively little has been written about the discourse features of these languages. One of these areas of discourse where relatively little research has been done is that of participant reference.

This thesis explores the features of participant reference in one Mixtec language, Xochapa Mixtec, by examining the use of nouns, pronouns, and deictic phrases in eight Xochapa Mixtec texts. The texts used in this research were transcribed from audio recordings and then analyzed with respect to the participant reference forms they employed. The thesis begins with …

Reference Tracking In Ethiopian Sign Language, Katelin Jo French

Theses and Dissertations

Very little has been written about Ethiopian Sign Language, but the language has obvious differences from more well-studied signed languages. This thesis focuses on striking differences in reference tracking: looking at all the different referring types—lexical items, points, eye gaze, body shift, agreement, and zero reference—and their distribution throughout narrative texts. Through this process, Ethiopian Sign Language has proved different from expectations based on previously studied signed languages. This language uses loci with much more flexibility, depending on role shift alone to strongly establish loci for entities. Another way this language differs from other languages is its lack of entity …

Education, Health & Behavior Studies Faculty Publications

Objective To estimate international and national temporal trends in the cardiorespiratory ftness (CRF) of adults, and to examine relationships between trends in CRF and trends in health-related, socioeconomic, and environmental indicators.

Methods Data were obtained from a systematic search of studies that explicitly reported temporal trends in the CRF of apparently healthy adults aged 18–59 years. Sample-weighted temporal trends were estimated using best-ftting regression models relating the year of testing to mean CRF. Post-stratifed population-weighted mean changes in percent and standardized CRF were estimated. Pearson’s correlations were used to describe associations between linear trends in CRF and linear trends in …

Intergenerational Transmission Of Child Abuse: Predictors Of Child Abuse Potential Among Racially Diverse Women Residing In Domestic Violence Shelters, Raeann E. Anderson, Larissa-Jayne Edwards, Kristin E. Silver, Dawn M. Johnson

Psychology Faculty Publications

Parental risk for perpetrating child abuse is frequently associated with intergenerational patterns of abuse: being abused increases the risk for future abuse. Yet, the mechanisms of intergenerational abuse are unclear, and the risk factors for perpetrating child abuse are interrelated. Research suggests that history of childhood abuse, psychiatric distress, and exposure to intimate partner violence (IPV) are all related risk factors for perpetrating child abuse. We investigated these three risk factors using the developmental psychopathology framework in a racially diverse sample of high-risk women: women residing in domestic violence shelters. 211 mothers residing in domestic violence shelters completed measures of …

Containers And Reproducibility In Scientific Research, Sara Faraji Jalal Apostal, David Apostal, Ronald Marsh

Computer Science Faculty Publications

Numerical reproducibility has received increased emphasis in the scientific community. One reason that makes scientific research difficult to repeat is that different computing platforms calculate mathematical operations differently. Software containers have been shown to improve reproducibility in some instances and provide a convenient way to deploy applications in a variety of computing environments. However, there are software patterns or idioms that produce inconsistent results because mathematical operations are performed in different orders in different environments resulting in reproducibility errors. The performance of software in containers and the performance of software that improves numeric reproducibility may be of concern for some …

English Learners And Mathematical Word Problem Solving: A Systematic Review, Virginia Clinton, Deni Lee Basaraba, Candace Walkington

Educational Foundations and Research Faculty Publications

Successful solution of mathematics word problems (MWPs) requires students to be able to understand the language of the MWP, which may be particularly challenging for English Learners (ELs). In this chapter, we review 21 empirical studies about specific linguistic features of MWPs, and the effects of modifying linguistic features on mathematics word problem-solving performance. Results of our review indicated that a variety of linguistic features has differential effects on the mathematics word problem-solving performance of ELs (compared to non-ELs), and that the effects vary by linguistic feature and grade level. Additionally, the effects of modifying the linguistic features of items …

Characterization And Consecutive Prediction Of Pore Structures In Tight Oil Reservoirs, Zhaohui Xu, Peiqiang Zhao, Zhenlin Wang, Mehdi Ostadhassan, Zhonghua Pan

Petroleum Engineering Faculty Publications

The Lucaogou Formation in Jimuaser Sag of Junggar Basin, China is a typical tight oil reservoir with upper and lower sweet spots. However, the pore structure of this formation has not been studied thoroughly due to limited core analysis data. In this paper, the pore structures of the Lucaogou Formation were characterized, and a new method applicable to oil-wet rocks was verified and used to consecutively predict pore structures by nuclear magnetic resonance (NMR) logs. To do so, a set of experiments including X-ray diffraction (XRD), mercury intrusion capillary pressure (MICP), scanning electron microscopy (SEM) and NMR measurements were conducted. …

The Aromatization Of Propene Via Nano-Size Hzsm-5, Wayne Seames, Swapnil Fegade, Inna Sakodynskaya, Darrin Muggli, Brian Tande, Alena Kubatova, Evguenii Kozliak

Chemistry Faculty Publications

Zeolite (ZSM) catalysts are known to convert small-size alkenes, e.g., propene, into aromatic hydrocarbons, specifically benzene, toluene and xylenes (BTX), with both high efficiency and specificity. The efficiency of conventional and hierarchical nano-size ZSM-5 for propene aromatization was compared in this study using a Design of Experiments (DOE) approach combined with detailed product analysis. Contrary to our expectations, the former showed a significantly greater BTX yield than the latter. Analysis of the obtained data by DOE and additional experiments with soybean oil cracking using both catalyst types indicated that a reason for the observed reduced activity of nano-scale zeolites may …

Comparison Of Deep Convolutional Neural Networks And Edge Detectors For Image-Based Crack Detection In Concrete, Sattar Dorafshan, Robert J. Thomas, Marc Maguire

Civil Engineering Faculty Publications

This paper compares the performance of common edge detectors and deep convolutional neural networks (DCNN) for image-based crack detection in concrete structures. A dataset of 19 high definition images (3420 sub-images, 319 with cracks and 3101 without) of concrete is analyzed using six common edge detection schemes (Roberts, Prewitt, Sobel, Laplacian of Gaussian, Butterworth, and Gaussian) and using the AlexNet DCNN architecture in fully trained, transfer learning, and classifier modes. The relative performance of each crack detection method is compared here for the first time on a single dataset. Edge detection methods accurately detected 53–79% of cracked pixels, but they …

Do Mindful Breathing Exercises Benefit Reading Comprehension? A Brief Report, Virginia Clinton, Sara Elizabeth Carlson, Megan Swenseth

Educational Foundations and Research Faculty Publications

A brief breathing exercise designed to induce a mindful state could benefit reading comprehension performance, but has not been previously examined. Furthermore, the mechanisms of how an induced mindful state benefits cognition are not well understood. The purposes of this study are to test the effectiveness of a brief mindful breathing exercise on reading comprehension performance and examine two potential mechanisms (mind wandering and stress reduction). Undergraduate students (N = 104) engaged in either a mindful breathing exercise or control sham exercise, indicated their stress levels, and completed a reading comprehension assessment during which they self-reported their mind wandering. The …

Determining The Respiratory State From A Seismocardiographic Signal - A Machine Learning Approach, Christian Ulrich, Martin Jensen, Rolf Oberlin, Kouhyar Tavakolian, Farzad Khosrow-Khavar, Andrew Blaber, Kasper Sørensen, Samuel Schmidt

Electrical Engineering Faculty Publications

Seismocardiography (SCG) is a non-invasive method for measurement of vibrations on the chest wall originating from the heart. Respiration changes the morphology of the SCG-signal and analyzing these changes could improve the diagnostic value of SCG. This study aimed to determine the nasal respiration signal amplitude at mitral closure (MC) and aortic opening (AO) using SCG features. The three proposed methods for this were multiple regression analysis (MRA), support vector regression (SVR), and a neural network (NN). SCG, Electrocardiography and nasal-catheter flow signals were acquired from 18 healthy subjects (age 29± 6). SCG-signal fiducial points were used as features and …
