A total of four hundred forty-nine (449) microplastic fragments were isolated …

A Framework For Assessing Environmental Incidents In Coastal Areas: A Case Study In The Southeastern Coastal Area Of Vietnam, Cuong Le Tan, Phuoc Nguyen Van, Quan Nguyen Hong, Loan Tran Thi Diem, Minh Tran Thanh

Applied Environmental Research

As developing dynamic regions, coastal areas have a high potential for environmental incidents, especially chemical spills, which may permanently threaten livelihoods and coastal ecosystems. Establishing an appropriate methodological framework for assessing environmental incidents in coastal areas, ensuring increased predictability and minimising potential consequences is a trend of interest to scientists. In this study, the environmental risk assessment model was applied to develop a framework for assessing environmental incidents in coastal areas due to chemical spills from the mainland based on hazard, exposure and vulnerability factors (i.e., sensitivity and adaptability). Using the multiple criteria decision-making (MCDM) method approach, suitable criteria, their …

An Urban Tree (Tabebuia Argentea) Exhibits Higher Sensitivity To Environmental Conditions Than An Urban Palm (Ptychosperma Macarthurii) Growing In The Same Roof Garden: An Implication For Sustainable Urban Water Use, Ratchanon Ampornpitak, Prangwilai Khobpee, Weerapong Unawong, Nisa Leksungnoen, Pantana Tor-Ngern

Applied Environmental Research

Roof gardening is popular for increasing green space in cities due to the restricted urban areas. However, when watering plants on a roof garden, one should consider loading capacity of the roof, which may limit water supply to the plants therein. To improve the efficiency in irrigating trees in a roof garden, we evaluated plant water status, represented by midday leaf water potential (ΨL), and leaf gas exchange parameters including stomatal conductance (gs) and net photosynthesis (An) of a tree (Tabebuia argentea, Ta) and a palm (Ptychosperma macarthurii, Pm) species, which dominate the garden. …

Utilizing Wasteaware Benchmark Indicators To Improve Municipal Solid Waste Management In Northern Thailand, Sujitra Vassanadumrongdee, Ridthipat Kallayanapattharasit, Arisara Lekkham, Pattayaporn Unroj

Applied Environmental Research

Primarily responsible for waste collection and disposal, local governments in northern Thailand face significant obstacles in managing waste. Mixing infectious, hazardous and general waste, over-utilizing incinerators and implementing environmentally improper disposal methods all contribute to burgeoning volumes of waste with adverse environmental and health impacts. The objectives of this study are to use the Wasteaware benchmark indicators (WABIs) to assess the effectiveness and sustainability of the waste management of Wiengthoeng Sub-district Municipality (WSM), to identify advantages and disadvantages of its system and offer fact-based recommendations for improvement. Pertinent data was obtained through interviews of governmental authorities, community members and private …

Impact Of Covid-19 Nationwide Lockdowns And Unlock Phases In India On River Water Quality Of Upper Part Of The Ganga River, Dhara Kakwani, Abha Kumari, Kumar Suranjit Prasad, Bablu Prasad

Applied Environmental Research

The river water quality index (RWQI) of the upper Ganga canal has been computed to assess the effect of lockdown and unlock phases lead down by COVID-19 in India. Geospatial distribution of RWQI from January 2019 to December 2021 in the study area revealed significant impacts of lockdown on water quality. However, unlock phases (post lockdown) have deteriorated water quality since August 2020 and reached to actual conditions of the river by August 2021. To evaluate the lockdown as a management strategy to clean the river, other factors were reviewed including rainfall data, migration, and other activities. The results revealed …

A Review Of The Effects Of Kinesio Tape Fascial Correction Technique Of The Iliotibial Band Relating To Myofascial Pain Syndrome, Austin James Hills

Health Nutrition and Exercise Science

This paper reviewed the effects of Kinesio Taping® on pain pressure threshold (PPT) of trigger points (TrPs) within the iliotibial band (ITB). The condition known as myofascial pain syndrome (MPS) is a chronic pain disorder where pressure or sensitive points in muscle tissue causes localized or referred pain. This disorder typically manifests chronically due to an overuse or overtraining mechanism. MPS has been identified in individuals of all ages, body types, and activity level. However, the population with the highest reported prevalence is individuals participating in moderate or higher levels of physical activity. Kinesio Taping® fascial correction technique claims an …

It is employed to save time and resources in training, as it does not require a large …

Humanity's Footprint: Tracing The Devastating Effects Of Climate Change Through Time, Elizabeth Ponto

Architecture Theses

The climate is changing, there is no doubt about that. Past and present practices are not enough, we need to change now. This excerpt gives an adequate explanation on the dire need for change, “Human experience and memory offer no good analogy for how we should think of those thresholds, but, as with world wars or recurrences of cancer, you don’t want to even see one. [talking about the degrees Celsius the earth warms on average] At two degrees, the ice sheets will begin their collapse, 400 million more people will suffer from water scarcity, major cities in the equatorial …

The Fight For Equality: African American Seabees During World War Ii, Victoria Castillo

War, Diplomacy, and Society (MA) Theses

This thesis outlines the Navy’s movement towards black inclusion from the beginning of World War I to the end of World War II through the lens of African American Seabees as well as the two integrated Seabee Battalions, 34^th and 80^th. While examining African American Seabees during World War II, one can see the injustices they were facing in the Navy. Seabees are one of the forgotten branches during World War II, but while examining the history of African Americans serving in the U.S. Navy and the Seabees, we start to understand how they were able to …

How Salinity Influences Soil Organisms: Earthworms, Archaea, Bacteria And Fungi, Cecelia Bartley Castleberry

Soil Science

Soil salinity is a naturally-occurring issue in the Great Plains. Current standards for saline soil designation are based on plant tolerance levels. This thesis expands salinity knowledge into salinity responses of other soil organisms. I used laboratory mesocosms to examine survival and fecundity or cocoon production of earthworms in the Apporectodea complex to increasing levels of salinity, with or without supplemental organic matter (OM). I then used a split-bin design to examine earthworm choice between combinations of saline and non-saline soils, with and without supplemental OM. I found that earthworms avoided saline soils, but survival and production was steady across …

Solving The Cherry-Picking Problem In Legislative History Use – A Corpus-Based Approach For Empirical Intentionalist Legal Interpretation Analysis, Brett James Hashimoto, James Heilpern

Faculty Publications

The use of legislative histories under intentionalist/purposivist theories of statutory interpretation is frequently criticized because it can be easily biased (see, e.g., Scheppele, 2012). To date, corpus-based statutory interpretation has relied almost exclusively on textualist theory of legal interpretation. However, corpus linguistic methods are not necessarily bound to any one theory (e.g., Biber & Reppen, 2015). The present study analyses two legislative histories as corpora and compares them against a general corpus of English to determine if interpretative theory makes a meaningful difference in two example cases (Costello v. United States, 2012; Taniguchi v. Kan Saipan Pacific, 2012). Senses of …

Corpus Of Founding Era American English: Designing A Corpus For Interpreting The United States Constitution, Brett James Hashimoto

Faculty Publications

The original meaning of words or phrases is often in dispute in Founding Era legislation, especially the US Constitution. The Corpus of Founding Era American English (COFEA) accurately provides evidence for the meaning of contested terms during the Founding Era. COFEA consists of 126,394 texts and over 136 million words. This corpus has been and is being used by legal researchers and interpreters in scholarly research as well as various courts, including the Supreme Court. This paper describes the motivation for the creation of COFEA and describes the process of designing and collecting the corpus.

Rapid Prediction Of Verbs Based On Pronoun Interpretation Is Modulated By Individual Differences In Pronoun Processing, Jeffrey Jack Green

Faculty Publications

How quickly can pronoun interpretation affect the prediction of a following verb? Readers were presented with implicit causality contexts in which a specific pronoun and following verb were predictable. N400 and reaction time results indicated that predictable verbs were facilitated relative to unpredictable verbs when following predicted pronouns, suggesting that verbal predictions were rapidly updated based on pronoun interpretation. There was also some evidence for rapid updating of verb predictions after unexpected pronouns, but this was modulated by individual differences. Some readers appear to have placed higher weight on top–down implicit causality predictions to interpret unexpected pronouns, and others on …

Utahns Sound Utahn When They Avoid Sounding Utahn, Joseph A. Stanley

“Someone In Their Corner”: Parental Support In Online Secondary Education, Courtney N. Hanny, Charles R. Graham, Richard E. West, Jered Borup

Faculty Publications

Despite increased interest in K–12 online education, student engagement deficits and the resulting student attrition remain widespread issues. The Academic Communities of Engagement (ACE) framework theorizes that two groups support online student engagement: the personal community of support and the course community of support. However, more evidence is needed to understand how members of these communities, especially parents, support students in various contexts. Using insights gleaned from 14 semi-structured interviews of parents with students enrolled in online secondary school, this study adds support to the roles identified in the ACE framework by presenting real examples of parents supporting their online …

Barriers And Enablers To K-12 Blended Teaching, Courtney N. Hanny, Karen T. Arnesen, Qi Guo, Jordan Hansen, Charles R. Graham

Faculty Publications

The attributes of post-pandemic blended teaching (BT) will more closely resemble pre-Coronavirus conditions than the outbreak’s emergency remote teaching. Thus, barriers and enablers for teachers transitioning to BT after emergency remote teaching will be similar to those of early BT adopters. K-12 research has identified external and internal barriers and enablers to technology integration but has largely overlooked those of BT. This study involved analyzing 62 interviews of K-12 blended teachers to discover factors that enabled BT, stood as barriers to initial and continued blending efforts, and helped teachers overcome barriers. Teacher-perceived barriers included, among others, costs perceived as outweighing …

A Preliminary Investigation Of A Brief Tier 1 Classroom Management Measure, Allison F. Gilmour, Joseph H. Wehby, Jessica Boyle, Howard P. Wills, Paul Caldarella

Faculty Publications

Multitiered systems for supporting students’ behavior in schools rely on teachers using generally effective classroom management strategies, such as Tier 1 practices. However, few tools exist to easily assess classwide Tier 1 practices. In this brief report, we describe one potential tool, the Classroom Atmosphere Rating Scale–Brief (CARS-B) and assess the properties of the tool using item response theory and multilevel models. We found that most items on the CARS-B had acceptable discriminations and difficulty estimates. Teachers’ CARS-B latent scores were positively associated with student group on-task. We discuss potential changes to the CARS-B and its use in research and …

The Icfr Process: Perspectives Of Accounting Executives At Large Public Companies, Eldar Maksymov, Jeffrey Pickerd, T. Jeffrey Wilks, Devin Williams

Faculty Publications

The Sarbanes-Oxley Act charges management with the primary responsibility for internal control over financial reporting (ICFR). However, prior research tells us little about the ICFR process from management’s perspective. We develop a theoretical model of the ICFR process from management’s perspective and examine that model by surveying 145 and interviewing 35 accounting executives at large US public companies. Our primary finding is that executives feel constrained in their ability to direct ICFR and hold perspectives that reflect these constraints. Specifically, most executives feel compelled by auditors to follow the PCAOB’s preferences even though executives believe these preferences often tend to …

Automatic Enrollment With A 12 Percent Default Contribution Rate, Josh Beshears, Ruofei Guo, David Laibson, Brigitte C. Madrian, James J. Choi

Faculty Publications

We study a retirement savings plan with a default contribution rate of 12 percent of income, which is much higher than previously studied defaults. Twenty-five percent of employees had not opted out of this default 12 months after hire; a literature review finds that the corresponding fraction in plans with lower defaults is approximately one-half. Because only contributions above 12 percent were matched by the employer, 12 percent was likely to be a suboptimal contribution rate for employees. Employees who remained at the 12 percent default contribution rate had average income that was approximately one-third lower than would be predicted …

Speed-Accuracy Tradeoffs In Decision Making: Perception Shifts And Goal Activation Bias Decision Thresholds, Jeff Larson, Guy Hawkins

Faculty Publications

A fundamental aspect of decision making is the speed-accuracy tradeoff (SAT): slower decisions tend to be more accurate, but because time is a scarce resource people prefer to conclude decisions more quickly. The current research adds to the SAT literature by documenting two previously unrecognized influences on the SAT: perception shifts and goal activation. Decision makers’ perceptions of what constitutes a fast or a slow decision, and what constitutes an accurate or inaccurate decision, are based on prior experience, and these perceptions influence decision speed. Similarly, previous experience in a decision context associates the context with a particular decision goal. …

Typing Fast Versus Typing Slow: Using Typing Dynamics To Reveal Authentic And Imposter Users, David Kim, Joseph S. Valacich, Jeffrey L. Jenkins, Manasvi Kumar

Faculty Publications

Real-time assessment of users' cognitive states has practical importance, allowing organizations to infer user behaviors. Realizing its importance, prior studies – specifically those using mouse cursor movements – have applied various theories to answer a similar question, i.e., how does a high cognitive load influence the users' device usage behavior? While numerous activities can increase cognitive load, we argue that the mechanisms behind how humans process information can more holistically be explained using Dual Process Theory (DPT) (i.e., when cognitive load is either low or high) and can be applied under a broad range of usage contexts. Using a within-participant …

Devour The Land: War And American Landscape Photography Since 1970, James R. Swensen

Faculty Publications

At first glance, it is apparent that this is not a typical art book or exhibition catalog. Spiral bound with various, variegated folios and sections, Devour the Land appears to be taken from a restricted archive. Indeed, everything down to the chosen fonts makes it seem as if this was a government record. Yet, it becomes quickly evident that this engaging text is not a report that federal authorities would like to broadcast. By subverting the look of a bureaucratic document, this text penetrates and probes the very system it wants to critique.

“A Tyrannical Grace”: Mabel Frazer, The American West, And The Navigation Of A Man’S Space, James R. Swensen

Faculty Publications

In 1949 the painter Mabel Frazer (1887–1981) applied for, and finally received, promotion to the position of associate professor of art at the University of Utah. Yet, after nearly three decades of diligent service, she witnessed her male peers, often with far fewer bona fides, receive advancement.1 This was the challenge, she acknowledged, of being a “woman in a man’s institution.”2 Throughout her career Frazer repeatedly overcame similar challenges and, by so doing, defied and redefined what it meant to be a female artist in Utah. This essay explores one of the significant ways in which Frazer’s work stretched gendered …

An Angry Face And A Guilty Conscience: The Intrapersonal Effects Of Fake Anger In Negotiation, David Hunsaker, Teng Zhang, Mckenzie Rees

Faculty Publications

Research on anger in negotiation suggests that expressing anger can have detrimental effects on the relationship between the parties but may also improve the expresser’s economic outcomes, resulting in the use of fake anger (i.e., anger that is expressed but not felt) as a negotiation strategy. Based on research on moral emotions, we argue that fake anger in negotiation will lead to expressers’ guilt, which in turn negatively impacts their self-perception and their overall subjective experience of the negotiation. Across three studies (two online and one face-to-face), we consistently demonstrate that fake anger lowers negotiators’ feelings about themselves as well …

Are We Essential, Or Sacrificial? The Effects Of Felt Public Gratitude On Essential Worker Recovery Activities During Covid-19, Hee Young Kim, Sijun Kim, Taeya M. Howell, Sarah P. Doyle, Nathan C. Pettit, Michael Bizzarro

Faculty Publications

COVID-19 has been characterized by unprecedented levels of public gratitude to some, but not all, essential workers. In this research, we integrate insights from the stigmatized occupations and gratitude literature to build theory on the positive and negative relationships between such displays of public gratitude and essential workers’ recovery activities. We argue that felt public gratitude positively relates to adaptive recovery activities (e.g., exercise) and negatively relates to maladaptive recovery activities (e.g., overdrinking). We further explain how felt public gratitude impacts (mal)adaptive recovery activities through (a) felt invisibility and (b) negative/positive affect. We find support for our predictions in a …

Dietary Counselling Of Children With Food Allergy, Julia Eisenblaetter

School of Health Professions Theses

Background: The management of food allergy is challenging for children and their families. Several international guidelines recommend involving dietitians in the management; however, their tasks remain uncertain, and the effectiveness of dietary counselling has rarely been investigated. Therefore, the aim of this project was to evaluate the effectiveness of dietary counselling in children with food allergy regarding food allergy related quality of life (QoL), number of allergic reactions, and growth as indicator of nutritional status and diet diversity. Methods: The project was guided by the Complex Intervention Model by the Medical Research Council. To reach the overall aim there needed …

Investigating Letter Identification For Visual Acuity Measurements In The Paracentral Visual Field, Hatem Barhoom

School of Health Professions Theses

Sloan letters are commonly used optotypes in clinical practice, but they exhibit different relative legibility, which may be attributed to response bias, sensitivity differences, and letter similarity. In this thesis, we employed Luce’s choice model and developed a new noisy template model to investigate the role of response bias, sensitivity differences, and letter similarity in letter identification of Sloan letters at central and paracentral locations. Results show that the best model was the one that accounted for the effects of bias, sensitivity, and similarity, with bias contributing more than sensitivity and similarity. However, when estimating the letter acuity from the …

Efficacy And Acceptability Of Mobilisation And Stretches Of The Foot And Ankle In People With Diabetic Peripheral Neuropathy, Vasileios Lepesis

School of Health Professions Theses

People with diabetic peripheral neuropathy and limited joint mobility syndrome (LJMS) can experience increased forefoot peak plantar pressures (PPPs). Elevated PPPs are a risk factor for diabetic neuropathic foot ulceration. Diabetic peripheral neuropathy can also affect balance and increase the risk of falling. This thesis investigated the efficacy and acceptability of foot and ankle mobilisations combined with home stretches in people living at risk of neuropathic diabetic foot ulceration and falling. A systematic review and meta-analysis examined the effects of foot and ankle physical therapy modalities for the management of foot and ankle joint mobility, PPPs, and balance. The review …

Enhancing Restaurant Dining Experience: Design And Evaluation Of A Mobile App For Personalized Menu Item Selection In Restaurants, Kimia Tuz Zaman

Computer Science

Picking the right food item from a restaurant menu can be challenging for people, specially for those who are unfamiliar with local cuisine and those with specific dietary requirements. Existing menus often lack essential information, making it difficult for diners to make quick and confident decisions. In this paper, we propose a mobile app that offers a user-friendly interface to allows users rank menu items based on their preferences and concerns. Using personalized ranking algorithms, the app analyzes the ingredients and nutritional content of menu items, providing users with valuable information to make informed choices. Preliminary tests suggest that the …
