Corticosteroids Treatment For Pediatric Acute Respiratory Syndrome: A Critical Review, Khouloud A. Al-Sofyani

Saudi Medical Journal

Approximately 25% of all pediatric consultations are due to respiratory conditions, 10% of which are for asthma. Regarding prevalence, bronchiolitis, acute bronchitis, and respiratory infections are other leading pediatric respiratory illnesses. Compared to the aforementioned diseases, pediatric acute respiratory distress syndrome (PARDS) is rare but lethal in the Intensive Care Unit patients. According to global studies, the mortality in PARDS ranges from 13.3% to 60.7%. Before the Pediatric Acute Lung Injury Consensus Conference (PALICC), adult acute respiratory distress syndrome (ARDS) management guidelines were used for PARDS. The PALICC set new criteria to identify PARDS with a different treatment and management …

Optimal R&D Investment In The Management Of Invasive Species, William Haden Chomphosy, Dale T. Manning, Stephanie A. Shwiff, Stephan Weiler

United States Department of Agriculture Wildlife Services: Staff Publications

Invasive alien species (IAS) threaten world biodiversity, ecosystem services, and economic welfare. While existing literature has characterized the optimal control of an established IAS, it has not considered how research and development (R&D) into new removal methods or technologies can affect management decisions and costs over time. R&D can lower the costs of control in a management plan and creates an intertemporal trade-off between quick but costly control and gradual but cheaper removal over time. In this paper, we develop and solve a continuous time dynamic optimization model to study how investment in R&D influences the optimal control of an …

The Negative Influence Of External Stressors On Patient Outcomes: Why Physicians Should Consider More Than Outwardly Presenting Symptom(S), Gianna Meckler '23

Honor Scholar Theses

In this thesis, the influence of external stressors on patient health outcomes in the medical setting will be examined. There is an overwhelming amount of reputable research that suggests that the American healthcare system, at least as it operates now, does not effectively improve patient health outcomes. Simply focusing on outwardly apparent illness or disease does not address the full scope of patient need. Ample evidence will be provided in the form of a comprehensive literature review accompanied by supporting anecdotes from real physicians in hopes of encouraging healthcare professionals to increase the breadth of their considerations when it comes …

Visual Literacy And Reading Motivation Understanding The Impact Of Illustrations And Images On An Individual’S Engagement With Text, Anna Mccuaig '23

Honor Scholar Theses

Education systems are currently facing an issue not of illiteracy, but aliteracy due to their emphasis on easily measured and taught content that ultimately removes much of what makes reading relatable and personally rewarding to students. Common Core State Standards, Accelerated Reader, and Hooked on Phonics are examples of measurement heavy programs which emphasize a standardized education that removes the art and connection that comes with literature. Before these programs, visuals have been intertwined with literature in various forms for centuries. Theater, the film, or even architecture has an important ability to create an immersive experience which connects its viewers …

A Pattern-Centered Analysis Of Adolescents' Concerns And Hopes About Future Crises: Differences In Ways Of Coping And Personal Adjustment, Melanie J. Zimmer-Gembeck, Katheryn L. Modecki, Ellen Skinner, Lara J. Farrell, Tanya Hawes

Psychology Faculty Publications and Presentations

Introduction

Many adolescents are concerned about global and future crises, such as the health of the planet or terrorism/safety. Yet, adolescents can also express hope about the future. Thus, asking adolescents about their concern and hope could yield subgroups with different ways of coping and personal adjustment.

Method

Australian adolescents (N = 863; age 10-16) completed surveys to report their concern (worry and anger) and hope about the planet, safety, jobs, income, housing, and technology, as well as their active and avoidant coping, depression, and life satisfaction.

Results

Four distinct subgroups were identified using cluster analysis: Hopeful (low on concern …

Impacts Of Attribution Style On Academics, Personal Relationships, And Extracurricular Activities: A Mixed Methods Study Of Learned Helplessness In Secondary Students, Joslyn Vendola

Graduate Doctoral Dissertations

The phenomenon of learned helplessness is the state in which an individual no longer views their outcomes as contingent upon their effort in response to previous failure outcomes and stressful events which were out of their control. Learned helplessness symptoms are often observed amongst students who experience other challenges simultaneously, such as low academic achievement, emotional disability (ED) diagnosis, and/or low-socioeconomic status (low-SES). The existing LH research focuses on identification, labeling, and offering interventions, such as learned optimism (LO) and attribution retraining. The lack of qualitative data, specifically student input, is a gap in the current body of research that …

Estimation Of Mortality Rates For The Gulf Menhaden Stock And Reference Point Implementation For The Fishery, Catherine Wilhelm

Master's Theses

The Gulf menhaden stock is the target of a large commercial fishery in the Gulf of Mexico. To address the needs of both the stock and fishery, I performed two studies. I first addressed the natural mortality rates currently used in the Gulf menhaden stock assessment. To update these rates, I used data from a tagging study conducted from 1970 to 1988. Adult and juvenile menhaden were tagged, released, and recovered in fish processing plants. To evaluate the data, I built a Bayesian model using the negative binomial distribution to estimate natural mortality, catchability, and the overdispersion factor parameters. I …

Toward Accelerometer Recording Of Pit Viper Foraging Behavior In Nature: Validation And Case Study With Timber Rattlesnakes (Crotalus Horridus), Morgan L. Thompson

Biology Theses

Accelerometer dataloggers are becoming increasingly common in field studies of animal behavior. Among the most difficult study subjects, and consequently, the most ideal candidates for accelerometer applications, are those for which simultaneous observation of key fitness-determining behaviors, such as foraging, across a sample of individuals in the wild is traditionally impossible or restricted to the use of proxy measures. This is the case for many solitary vertebrate predators, such as all pit vipers (Viperidae; Crotalinae). Large-bodied pit vipers are ambush (sit-and-wait) specialists that represent uniquely challenging and intriguing study subjects in predator ecology. Unlike many comparable avian or mammalian terrestrial …

Functional Analysis Of Daxx In Tumorigenesis Of Pancreatic Neuroendocrine Tumors And Embryonic Development, Chang Sun

Dissertations and Theses (Open Access)

Death domain-associated protein 6 (Daxx) is a histone chaperone specific to Histone 3.3 (H3.3). DAXX interacts with ATRX forming a chromatin remodeling complex, which deposits H3.3 into telomeric and pericentric region of the genome. The importance of Daxx was manifested in embryonic development. The loss of Daxx leads to early lethality in mouse embryos around E6.5. Moreover, sequencing studies have revealed the importance of DAXX in human tumors. Mutually exclusive mutations in DAXX and ATRX occur in about 30% of pancreatic neuroendocrine tumors (PanNETs). Although lots of progress has been made in studying functions of DAXX, we still do not …

Pronombres De La Tercera Persona Del Zapoteco De Macuiltianguis [Third Person Pronouns In Macuiltianguis Zapotec], Paula Margarita Foreman

Theses and Dissertations

As attested in Marlett (2010), the Zapotec languages of Oaxaca, Mexico, exhibit great variation within their pronominal systems. Based on my knowledge as a native speaker, I present a description of third-person pronouns in the Zapotec from the town of San Pablo Macuiltianguis (MacZ) (ISO 639-3 [zaa]) (Eberhard, Simons, & Fennig 2023), part of the Sierra de Juárez Juárez within the Sierra Norte branch of Zapotec (Smith Stark 2007). MacZ has four categories of third person pronouns (which can be called formal, general, child, and animal). The child and animal pronouns are generally optional, used to emphasize affection. The choice …

Anti-Doping Crisis In Sports, What's Next? Ion Mobility-Mass Spectrometry For The Study Of Anabolic Androgenic Steroids, Diana Constanza Velosa

Theses and Dissertations

The main objective of this work is to augment both qualitative and quantitative measures of anabolic androgenic steroids (AAS) with ion mobility-mass spectrometry (IM-MS), laying the foundation for implementation into analytical drug testing laboratories. AAS testing requires high sensitivity and specificity. IM-MS is presented as an emerging technology workflow capable of targeted quantification of AAS and structural elucidation for potential unknowns, allowing ions to be separated and characterized based on their rotationally averaged collision cross section (CCS). Chapter 1 provides a background of the basic principles of IMS and the different types of analytical methods used for doping analysis currently …

Xeno-Free Biomimetic Ecm Model For Investigation Of Matrix Properties On Astrocyte Cell Response, Bayan Saleh

Theses and Dissertations

Astrocytes are crucial in preserving the structural and functional integrity of the central nervous system (CNS). They participate in several physiological processes, such as the uptake of neurotransmitters, control of extracellular ion concentration, and preservation of the blood-brain barrier. Recent research has raised the possibility that astrocytes are also involved in the onset and development of Alzheimer's disease (AD). While the precise mechanisms underlying the development and progression of AD are not fully understood, recent research has suggested that age-related changes in the brain extracellular matrix (ECM) properties may play a critical role in the progression of the disease. Investigating …

The dissertation is divided into three main parts: the first part focuses on research using different drift gases and ion adducts to modify the mobility separations allowing for resolution between the isomers. The second part focuses on research exploring derivatization reactions that target structural differences between the steroid hormone isomers to amplify the differences and resolve the isomers in the ion mobility region. The final part covers a proposal on future study directions to include simultaneous derivatization reactions, mass spectrometry fragmentation, …

Effect Of Brain Injury On Demand Of Alcohol, Whitney Michele Chaney

Theses and Dissertations

Brain injury, or damage to the brain and/or surrounding structures, is listed by the CDC as the leading cause of disability and death in the United States. This kind of injury can result in symptoms that physical, cognitive, and behavioral functioning in those affected. Despite this, current literature reflects a significant deficiency in the understanding and management of behavioral symptoms, that present after the injury, in most neurorehabilitative treatments. This study aimed to investigate whether sustaining a brain injury can effect an individual’s demand intensity for alcohol, if their demand was inelastic, and their probability for misuse of alcohol. To …
