Heat Related Illnesses: Review Of An Ongoing Challenge, Anas A. Khan

Saudi Medical Journal

Climate change is the most challenging natural calamity of chronic nature that presents intense episodes of heat waves, and events. Effects of heat waves and increasing average temperature on heat-related illnesses (HRIs) demand a review of existing preventive and treatment strategies to direct future research. Heat-related illnesses are presented as minor to severe life-threatening conditions. Despite the understanding of the pathophysiology of HRI, pharmacological interventions are limited. Prevention is the best strategy against HRI. There is a dearth of epidemiological studies that reviewed the effect of pharmacological interventions on mortality, and there remains a need to identify critical key components …

Changes In The Diet And Body Size Of A Small Herbivorous Mammal (Hispid Cotton Rat, Sigmodon Hispidus) Following The Late Pleistocene Megafauna Extinction, Catalina P. Tomé, Emma A. Elliott Smith, S. Kathleen Lyons, Seth D. Newsome, Felisa A. Smith

School of Biological Sciences: Faculty Publications

The catastrophic loss of large-bodied mammals during the terminal Pleistocene likely led to cascading effects within communities. While the extinction of the top consumers probably expanded the resources available to survivors of all body sizes, little work has focused on the responses of the smallest mammals. Here, we use a detailed fossil record from the southwestern United States to examine the response of the hispid cotton rat Sigmodon hispidus to biodiversity loss and climatic change over the late Quaternary. In particular, we focus on changes in diet and body size. We characterize diet through carbon (δ¹³C) and nitrogen …

Death Of Copyright, Paul Gugliuzza

Faculty Scholarship

The four primary bodies of intellectual property law—patent law, copyright law, trademark law, and the law of trade secrets—address the question of duration in different ways. Trade secrets have no fixed duration; the law protects against misappropriation as long as the relevant information remains secret. Trademark protection lasts as long as the mark retains its capacity to distinguish the goods or services it is attached to. In patent law—my primary area of scholarship—duration is fixed, finite, and generally straightforward to determine: you get twenty years from the date you file your patent application. Copyright duration, by contrast, varies depending on …

The Unnecessary And Unfortunate Focus On “Animus,” “Bare Desire To Harm,” And “Bigotry” In Analyzing Opposition To Gay And Lesbian Rights, James E. Fleming

Faculty Scholarship

I am delighted to participate in this symposium on Professor Linda C. McClain’s wonderful new book, Who’s the Bigot? Learning from Conflicts over Marriage and Civil Rights Law. All of the other papers in this symposium focus on Masterpiece Cakeshop, Ltd. v. Colorado Civil Rights Commission (and thus connect with Chapter Eight of her book, on claims of religious exemptions from protections of gay and lesbian rights), while my piece will join issue with the related Chapter Seven, on bigotry, motives, and morality in the Supreme Court’s gay and lesbian rights cases. In this brief Essay, I cannot do justice …

Deep Fakes: A Looming Challenge For Privacy, Democracy, And National Security, Robert Chesney, Danielle K. Citron

Faculty Scholarship

Harmful lies are nothing new. But the ability to distort reality has taken an exponential leap forward with “deep fake” technology. This capability makes it possible to create audio and video of real people saying and doing things they never said or did. Machine learning techniques are escalating the technology’s sophistication, making deep fakes ever more realistic and increasingly resistant to detection. Deep-fake technology has characteristics that enable rapid and widespread diffusion, putting it into the hands of both sophisticated and unsophisticated actors. While deep-fake technology will bring with it certain benefits, it also will introduce many harms. The marketplace …

The sale is open to 4-H and FFA members who qualified their livestock at the annual Dixie National Junior Round-Up. While youth livestock sales programs are commonly found at state and county fairs throughout the United States, demographic information and information concerning financial and life skill impacts of the program on participants is limited. Therefore, a survey instrument for the 2018 sale was designed to determine how the event has impacted the financial burden …

An Evaluation Of Unmanned Aerial Systems And Structure-From-Motion For Fluvial Large Wood Sensing And Risk Assessment, Daniel Gerke

Masters Theses

This research aims to show Unmanned Aerial System (UAS) and Structure-from-Motion (SfM) technology can, in combination, improve on traditional large wood (LW) monitoring techniques. More temporally and economically efficient data collected at a finer spatial resolution and greater spatial extent will increase the effectiveness of management plans and risk assessment for LW by providing decision-makers with a complete picture of the river.

Contemporary practices are too inefficient in time and labor for large-scale monitoring of fluvial LW with anything more than the most general management or risk assessment in mind. The paradigm of river research, the river continuum concept (RCC), …

Reconsidering ‘Soul And Body Ii’: Who Is Culpable For Their Combined Fate?, Sarah Jaran

Masters Theses

Soul and Body II has been considered for many years by scholars to be a less doctrinally complex poem compared to later versions of the topos. Superficially, the poem seems to blame the body fully for the shared doomed fate of the body and soul because the majority of the poem is a speech by the soul claiming that much. I propose in this study, however, that the poet created a dual message for the audience of Soul and Body II. While the easy and more superficial message is that the body is at fault for the damnation of …

Development And Employment Of Environmental Dna Methods For The Detection Of Bull Sharks (Carcharhinus Leucas) In A Freshwater And Estuarine Interface In The Mobile-Tensaw Delta And Mobile Bay, Alabama, Katherine Schweiss

Master's Theses

Species conservation and management is influenced by the quality of monitoring methods employed, especially when targeting elusive, but ecologically significant species, like elasmobranchs. Bull Sharks (Carcharhinus leucas) are highly mobile predators that rely on estuaries and freshwater rivers for maturation, resources, and refuge; their ability to withstand changing environmental conditions may mean they are linking ecosystems through their habitat usage and movements. Rather than setting nets or attaching acoustic monitoring devices, which can be expensive, time-consuming, and invasive, the analysis of environmental DNA (eDNA) for tracing species presence was used to target C. leucasDNA. The present research …

A Heavy Burden: Associations Between Sexual Minority Status, Mental Health, And Bmi In Women, Alison E. A. Goldblatt

Graduate Masters Theses

Sexual minority women (SMW) are at increased risk of elevated body mass index (BMI) compared to heterosexual women, which increases their vulnerability to a variety of chronic diseases. This increased risk of elevated BMI is likely due to unique minority stressors faced by sexual minority individuals, such as internalized heterosexism and discrimination. Minority stressors are associated with poorer mental and physical health among SMW, and SMW may engage in unhealthy coping strategies, like binge eating, to cope with these minority stressors. Research suggests that bisexual women, and other women with non-monosexual orientations, face elevated risks to their physical and psychological …

Climate Change Impacts On Phosphorus Loads In The Upper And Middle Charles River Watershed With Hspf Modeling, Meagan Riley

Graduate Masters Theses

Water quality in the Upper and Middle Charles River Watershed has improved over the past several decades primarily due to improvements statewide in wastewater management. However, climate change threatens this progress, with future projections promising increased precipitation and temperatures for the New England region. This study investigated the impact of climate change projections on total phosphorus loads in the Upper and Middle Charles River Watershed using the HSPF model. Model input data were extended through 2018 to update present day conditions represented by the previously calibrated and validated HSPF model. The updated model was then used to simulate the following …

Effects Of Visual Impairment On The Preparation, Response, And Recovery From The 2017 Hurricane Season In Puerto Rico, Kevin D. Mccormack

Graduate Doctoral Dissertations

The 2017 hurricane season in Puerto Rico brought rain and wind forces the likes of which had not been seen in 90 years on the island. Some say it will take at least ten years to recover from the damage caused to functional necessities such as roadways, assuming full recovery is possible. While the general populace in Puerto Rico struggled to recover, populations such as people with visual impairments experienced the struggle more acutely. Independent living, limited as it generally was before Hurricane Maria, was further compromised. There was a feeling of abandonment throughout the community of people with visual …

Oblivion, Deema Ali

Theses

Oblivion tells a story of a plain-looking individual named Miech at a gritty, damp subway station en route to catch a movie. As he waits for a train, he faces a troubling memory of a past relationship and is confronted by a projection of his inner emotions that takes the form of a creature. In a desperate attempt to escape from this manifestation, he shifts his attention to his external surroundings only to find that his fellow commuters also have similar creatures. In Oblivion, I address a very human experience through the spectacle of an animated lens. This film is …

Early Recruitment Of Crassostrea Virginica To Restored And Natural Oyster Reefs In The Western Mississippi Sound: Larval Supply And Post-Settlement Success, Leah Morgan

Master's Theses

The eastern oyster (C. virginica) is a foundation species that improves water quality, protects shorelines, provides refuge for other organisms, and contributes to commercial fisheries. Successful early recruitment of eastern oyster is vital for resupplying adult populations in the face of habitat loss. Coastal oyster populations are challenged by freshwater input, hypoxia, predation and overfishing. Consequently, substantial efforts have been dedicated toward oyster restoration within the northern Gulf of Mexico. The overall objective of this study was to consider the role and importance of early recruitment to oyster restoration in western Mississippi Sound. During the summer 2018 recruitment period, we …

Distribution, Abundance, And Trophic Ecology Of Anguilliform Leptocephali In The Northern Gulf Of Mexico, Lillian Collins

Master's Theses

All species of anguilliform eels have pelagic leptocephalus larval stages, which provides a means of monitoring the population dynamics of these otherwise cryptic and hard to study species. The goals of this study were to: 1) describe the distribution and abundance of anguilliform eel leptocephali across the northern Gulf of Mexico, and 2) examine the trophic ecology of leptocephali using stable isotope values of carbon and nitrogen (δ13C and δ15N). A 25-year (1990-2014) ichthyoplankton dataset provided by the National Oceanic and Atmospheric Administration (NOAA) Southeast Area Monitoring and Assessment Program (SEAMAP) was used to examine interannual variations in leptocephalus distribution, …

Terrorism And Organized Crime: An Analytical Study From An International Law Perspective, Leila Mejdoubi

Master's Theses

With the spread of terrorism and its growing risks since the start of the 21^st century, a wide range of reports and studies have emerged. This funding comes from a special relationship between terrorist organizations, organized crime syndicates, and their cooperation with each other, which has enabled terrorist organizations in particular to carry out recruitment efforts and operations alike. It has also fueled an international black market for smuggling and trade in drugs and arms. Under what conditions do violent terrorist groups driven by extreme Islamist ideology collaborate with organized criminal enterprises to generate the requisite resources to pursue …

Ancestral Pueblo Pottery: Cataloguing, Curation, Mount-Making And More, Elizabeth Jennings

Undergraduate Honors Theses

Ancestral Pueblo pottery is some of the most renowned pottery of its kind in North America, yet outside of the archaeology and art history communities its beauty and complexity is not well known. The University of Northern Colorado has a vast and remarkable collection of artifacts, predominately comprised of Native American pottery and ceramics. This collection was not previously widely accessible, partially because it was not published. The purpose of my research was to create an exhibition highlighting this collection of Ancestral Pueblo pottery in Michener Library at University of Northern Colorado, as well as an interactive touch screen kiosk …

Pre-Test Processing Differences Of Test Anxious Students, Michelle M. Garcia

Undergraduate Honors Theses

The purpose of this study was to investigate the pre-testing differences in persons with test anxiety (TA) comparted to person without test anxiety. Specifically, the study focused on differences in test preparation and study methods between groups. Further understanding of pretest differences regarding the processing and study methods of TA students may lead to the development of interventions that improve the deficits experienced by those with TA. All participants were administered the Cognitive Test Anxiety Inventory (CTAI) designed by Cassady and Johnson (2002). Persons that scored above the mean of 73.1 were classified as having TA, those who scored below …

Patch Size As A Niche Dimension: Aquatic Insects Behaviorally Partition Enemy-Free Space Across Gradients Of Patch Size, William J. Resetarits, Matthew R. Pintar, Jason R. Bohenek, Tyler M. Breech

Faculty and Student Publications

© 2019 by University of Chicago. Positive correlation of species richness with area is ubiquitous in nature, but the processes driving that relationship, as well as those constraining typical patterns, remain elusive. Patch size variation is pervasive in natural systems, and it is thus critical to understand how variation in patch size, as well as its potential interaction with factors like predation and isolation, affects community assembly. We crossed patch quality (fish presence/absence) with patch size to the examine effects of quality, size, and their interaction on colonization by aquatic insects. Overall, beetles favored small, fishless patches, but individual species …

Do My Students Understand? Automated Identification Of Doubts From Informal Reflections, Siaw Ling Lo, Kar Way Tan, Eng Lieh Ouh

Research Collection School Of Computing and Information Systems

Traditionally teaching is usually one directional where the instructor imparts knowledge and there is minimal interaction between learners and instructor. With the focus on learner-centred pedagogy, it can be a challenge to provide timely and relevant guidance to individual learners according to their levels of understanding. One of the options available is to collect reflections from learners after each lesson to extract relevant and high-value feedback so that doubts or questions can be addressed in a timely manner. In this paper, we derived an approach to automate the identification of doubts from the informal reflections through features analysis and machine …

Self-Organizing Neural Networks For Universal Learning And Multimodal Memory Encoding, Ah-Hwee Tan, Budhitama Subagdja, Di Wang, Lei Meng

Research Collection School Of Computing and Information Systems

Learning and memory are two intertwined cognitive functions of the human brain. This paper shows how a family of biologically-inspired self-organizing neural networks, known as fusion Adaptive Resonance Theory (fusion ART), may provide a viable approach to realizing the learning and memory functions. Fusion ART extends the single-channel Adaptive Resonance Theory (ART) model to learn multimodal pattern associative mappings. As a natural extension of ART, various forms of fusion ART have been developed for a myriad of learning paradigms, ranging from unsupervised learning to supervised learning, semi-supervised learning, multimodal learning, reinforcement learning, and sequence learning. In addition, fusion ART models …

Playing Isn’T Just For The Kids: The Effects Of Video Modeling On Adult Play Behavior, Grace Fancine Boatman

Theses and Dissertations

Children with Autism Spectrum Disorder lack appropriate play skills. To provide quality care to these children, practitioners who work with these children should be versed in how to play. The researchers for the current study used a multiple baseline design across stimulus sets. A pre-experimental assessment, naturalistic generalization probe, and a toy generalization probe were conducted prior to baseline. The baseline phase demonstrated the participant’s performance in playing with a confederate researcher. Task clarification represented the participant’s performance in playing with a confederate researcher after a verbal prompt to play more. The researchers implemented video modeling to increase the frequency …

Examining The Impact Of Standardized Fine Motor Activity Selection On Various Fine Motor Skills In Children With Autism Spectrum Disorder, Cheyenne Lee Dong

Theses and Dissertations

Many children with Autism Spectrum Disorder (ASD) demonstrate deficits in fine motor skills, requiring therapies to help improve their performance of a variety of self-care, daily living, and academic skills. Research in the occupational therapy literature suggests several methods of assessing and teaching fine motor skills and represents an area that is understudied in the applied behavior analysis research. The two disciplines may offer a complementary approach to targeting emerging skills, shaping desired responses in naturalistic contexts, and reinforcing participation. This study aimed to examine the impact of occupational therapy-recommended activities on fine motor skills by blending the occupational therapy …

A Quantitative Analysis Of Errors During Conditional Discriminations: Changing Sample-Stimuli Disparity In Delayed Matching-To-Sample Task With Children Diagnosed With Autism Spectrum Disorder, Tiara Rahadian Putri

Theses and Dissertations

Conditional discrimination skill is foundational in teaching many other functional skills in children diagnosed with Autism Spectrum Disorder (ASD) and error occur during training. Antecedent- and consequence-based intervention are commonly used without the understanding of underlying behavioral mechanism responsible for these errors. A quantitative framework based on choice- and signal-detection analyses (Davison & Tustin, 1978) was used to quantify and categorize errors. Three children diagnosed with ASD participated. The current study used an automated 0-s delayed matching-to-sample (DMTS) procedure on an iPad Pro® 9.7”. Four experimental conditions were arranged successively, wherein each corresponded with a level of sample stimuli disparity: …

The Effects Of Lag Reinforcement Schedules And Differential Reinforcement Of Alternative Responding On Reinforced Variability And Resurgence, Weizhi Wu

Theses and Dissertations

Differential reinforcement of an alternative responding (DRA) is a commonly used procedure to teach children with ASD more functionally and socially appropriate skills and decrease problem behavior. However, resurgence of problem behavior could occur when treatment integrity errors appearing while implementing DRA procedure. In research, one approach to mitigating resurgence is to reinforce varied alternative responses using a lag schedule. A lag schedule of reinforcement is a method to increase variability in which a reinforcer will be delivered contingently if the response differs from a certain number of previous responses. The present laboratory study evaluated whether reinforced behavioral variability could …

A Compositional Analysis Of Artificial And Terrestrial Analog Martian Regolith Simulants, Beverly Watson Kemmerer

Theses and Dissertations

Over the past 50 years, significant advances in the knowledge of the topography, climate, and geology of Mars have taken place. The global Martian regolith composition is highly basaltic, primarily composed of pyroxene, plagioclase, and olivine, a mixture of Fe oxides and Fe-Ti oxides, and some alteration minerals, i.e. sulfates, carbonates, and clays. The particle size distribution of Martian regolith ranges from 1 µm to 1000 µm, with average Martian soil grain sizes being 250 µm to 300 µm. These regolith properties, as well as geotechnical properties, all play a part in the outcome of certain in situ resource utilization …
