Turkish Journal of Zoology
Communal nest egg-laying refers to females laying their eggs with those of their conspecifics under or within artificial or natural structures. Homonota aff. darwinii is a recently discovered species that has not yet been formally described. The objective of this work is to characterise the oviposition of this species in the Puna region in the Central Andes of Argentina. We recorded the type and surface of the rocks where the eggs were laid, the temperature of the substrate, and the temperature of the rock surface facing the substrate. In addition, we recorded the daily temperature variation that a randomly selected …

INTRODUCTION: The number of surgical extractions performed in hospitals in England remains unclear. This study reports the volume of surgical extractions conducted in hospitals and change in activity during the COVID-19 pandemic.
METHODS: We conducted a nationwide observational cohort study using Hospital Episode Statistics (HES) in England for patients undergoing surgical removal of a tooth (defined using OPSC-4 code F09) between April 1, 2015, and December 31, 2020. Procedures were stratified by age, gender, and urgency (elective or nonelective), reported using descriptive statistics, number, and percentage. We conducted post hoc modeling to predict surgical activity to December 2023. In addition, …
The Impact Of Permit Concealed Carry And Social Factors On Firearm Fatalities, Witty Kwok, Jacob Weaver
The Impact Of Permit Concealed Carry And Social Factors On Firearm Fatalities, Witty Kwok, Jacob Weaver
Scholarship in Medicine - All Papers
A tragic amount of gun fatalities occur in today's world. These fatalities can be from acts of aggression, negligence, or accidental, but nonetheless are taking lives at an alarming rate. There has been a call to action to make changes and begin combating these issues, with the most commonly proposed solution being firearm regulation. This study aimed to assess the effectiveness of firearm legislation, specifically of concealed carry regulations, on controlling firearm fatalities while also attempting to identify underlying causes or predictors of firearm fatalities. In an attempt to simplify the many regulations implemented differently between states, this study looked …

A Comparative Study Of Biocrusts On Gypsum And Non-Gypsum Soils In The Northern Chihuahuan And Eastern Mojave Deserts, Usa: Biocrust Mosses Respond To Soil, Environmental, And Climatic Conditions, Katelyn Gobbie
Masters Theses
Biological soil crust communities (biocrusts) growing on gypsum soils have been well- documented for their prolific appearance and rich diversity of lichens and bryophytes. However, studies characterizing gypsum biocrusts have primarily occurred outside of the U.S., most of which lack comparisons to other soil types. We conducted intensive field surveys to evaluate the cover and frequency of biocrust functional groups and moss species on gypsum and non-gypsum soils in the U.S. regions with the most extensive gypsum outcrops, the northern Chihuahuan and eastern Mojave Deserts. We employed canonical correspondence analysis (CCA) to relate the observed differences in biocrust abundance and …

Human papillomavirus (HPV) is the most common sexually transmitted infection in the United States; yet, despite the availability of safe and effective HPV vaccines, only half of eligible adolescents have completed the vaccine series. School-entry requirements are one proven strategy to increase vaccination rates among children and youth and reduce the burden of HPV-related cancer. This study investigated community perceptions of an HPV vaccine school-entry mandate in Virginia and the consequences of a low threshold exemption option included in the legislation. We conducted 40 interviews with community members including 15 interviews with parents, 19 with healthcare providers, and 6 with …

Plant growth and food security depend heavily on phosphorus (P). Recovering and recycling P from animal, municipal, and food waste streams can significantly reduce dependency on traditional mineral P. This is particularly pertinent in the EU regions with limited native P supplies. The agronomic performance of including P-based recycling-derived fertilisers (two struvite and two ashes) or cattle slurry was compared to a conventional mineral P fertilisation programme along with no P and no fertiliser controls over three years. A field-scale experiment was set up to evaluate the perennial ryegrass dry matter yield (DMY), P uptake, and soil test P effects. …

Temperature is a primary factor influencing organismal development, and the fluctuating daily and seasonal thermal regimes of temperate climates may challenge the ability of viviparous reptiles to optimize body temperatures during gestation. Testing how viviparous reptiles navigate highly variable thermal conditions (e.g., relatively cold nights and/or highly fluctuating temperatures) is a powerful way to understand how they use microhabitats for thermoregulatory benefits. We assessed the thermal ecology of pregnant and non-pregnant female prairie rattlesnakes (Crotalus viridis) inhabiting a high-elevation, montane shrubland in northwest Colorado throughout their short summer active season, addressing the thermal consequences of microhabitat selection with …

Living Datasets: Towards Data-Centric Ai Explainability And Bias Mitigation, Akib Zaman
Computer Science and Engineering Dissertations - Archive
Benchmark datasets are critical to the evolution of AI efforts yet often embed unintended biases that influence the models that drive human-AI interactions. A deeper inspection and awareness of data is needed to understand the biases datasets may contain. In this dissertation, I introduce the Tag-and-Release method, inspired from wildlife research, that treats data as an organism and examines how different environments (i.e., CNNs) select for unique traits or characteristics that ultimately impact data's survival. Using the canonical MNIST handwritten digit dataset as a case study, I describe how the Tag-and-Release method can be used to analyze how dataset imbalance …
Does Assessment Of Distress Disclosure Enhance Prediction Of Suicidal Ideation In The Three-Step Theory Of Suicide?, Jessica A. Ruiz
Does Assessment Of Distress Disclosure Enhance Prediction Of Suicidal Ideation In The Three-Step Theory Of Suicide?, Jessica A. Ruiz
Graduate Thesis and Dissertation 2023-2024
The three-step theory of suicide (3ST) proposes that suicidal ideation (SI) and behavior develops in the context of unbearable pain and hopelessness (Step 1), low social connection (Step 2) and acquired capability (Step 3 - not assessed in this study; Klonsky et al., 2016). Distress disclosure is one way a person may utilize their social network to mitigate feelings of distress and can be a critical measure of social connectedness. Building on efforts to diversify measurement of social connectedness in the 3ST, a sample of 549 college students (mean age = 19.27, SD = 1.28; 56.6% reporting history of SI) …
Teacher Agency In Dual Language Programs: Examining Constraining And Facilitating Factors Through An Ecological Lens, Marcio R. Soares Gomes
Teacher Agency In Dual Language Programs: Examining Constraining And Facilitating Factors Through An Ecological Lens, Marcio R. Soares Gomes
Graduate Thesis and Dissertation post-2024
In the state of Florida (USA), several public schools offer dual-language education programs that include the equal use of Spanish and English to teach both English to speakers of other languages, the vast majority of whom are immigrants, and Spanish to school-age speakers of the majority language. Using the ecological approach (Priestley et al., 2015), as defined by Emirbayer and Mische’s (1998), this study seeks to understand how teachers in dual language programs achieve agency to protect the interests of their English learners. Through the lens of the ecological perspective, the study attempts to answer the following research questions: i) …
Governance Policy Evaluation In The United States During The Pandemic: Nonpharmaceutical Interventions Or Else?, Danlin Yu, Shenyang Guo, Yuanyuan Yang, Linyun Fu, Timothy Mcbride, Ruopeng An
Governance Policy Evaluation In The United States During The Pandemic: Nonpharmaceutical Interventions Or Else?, Danlin Yu, Shenyang Guo, Yuanyuan Yang, Linyun Fu, Timothy Mcbride, Ruopeng An
Department of Earth and Environmental Studies Faculty Scholarship and Creative Works
Scientific evidence suggests that nonpharmaceutical interventions (NPIs) effectively curb the spread of COVID-19 before a pharmaceutical solution. Implementing these interventions also significantly affects regular socioeconomic activities and practices of social, racial, and political justice. Local governments often face conflicting goals during policymaking. Striking a balance among competing goals during a global pandemic is a fine science of governance. How well state governments consume the scientific evidence and maintain such a balance remains less understood. This study employs a set of Bayesian hierarchical models to evaluate how state governments in the United States use scientific evidence to balance the fighting against …
