We study the processes e⁺e⁻→2(π⁺π⁻)π⁰π⁰π⁰γ and 2(π⁺π⁻)π⁰π⁰ηγ in which an energetic photon is radiated from the initial state. The data were collected with the BABAR detector at SLAC. About 14 000 and 4700 events, respectively, are selected from a data sample corresponding to an integrated luminosity of 469  fb⁻¹.The invariant mass of the hadronic final state defines the effective e⁺e⁻ center-of-mass energy. The center-of-mass energies range from threshold to 4.5 GeV. From …

Comparable Response Of Wild Rodent Gut Microbiome To Anthropogenic Habitat Contamination, Anton Lavrinienko, Ann Hämäläinen, Rasmus Hindstrom, Eugene Tukalenko, Zbyszek Boratynski, Kati Kivisaari, Timothy Mousseau, Phillip C. Watts, Tapio Mappes

Faculty Publications

Species identity is thought to dominate over environment in shaping wild rodent gut microbiota, but it remains unknown whether the responses of host gut microbiota to shared anthropogenic habitat impacts are species-specific or if the general gut microbiota response is similar across host species. Here, we compare the influence of exposure to radionuclide contamination on the gut microbiota of four wild mouse species: Apodemus flavicollis, A. sylvaticus, A. speciosus and A. argenteus. Building on the evidence that radiation impacts bank vole (Myodes glareolus) gut microbiota, we hypothesized that radiation exposure has a general impact on rodent gut microbiota. Because we …

Response Shift In Patient‑Reported Outcomes: Defnition, Theory, And A Revised Model, Antoine Vanier, Frans J. Oort, Leah Mcclimans, Nikki Ow, Bernice G. Gulek, Jan R. Böhnke, Mirjam Sprangers, Véronique Sébille, Nancy Mayo, Response Shift - In Sync Working Group

Faculty Publications

Purpose

The extant response shift definitions and theoretical response shift models, while helpful, also introduce predicaments and theoretical debates continue. To address these predicaments and stimulate empirical research, we propose a more specific formal definition of response shift and a revised theoretical model.

Methods

This work is an international collaborative effort and involved a critical assessment of the literature.

Results

Three main predicaments were identified. First, the formal definitions of response shift need further specification and clarification. Second, previous models were focused on explaining change in the construct intended to be measured rather than explaining the construct at multiple time …

We present a measurement of R_k+ , the branching fraction ratio B(B → K⁺μ⁺μ⁻)=B(B → K*e⁺e⁻),, for both charged and neutral B mesons. The ratio for the charged case R _K^* + is the first measurement ever performed. In addition, we report absolute branching fractions for the individual modes in bins of the squared dilepton invariant mass q². The analysis is based on a data sample of 711 fb⁻¹, containing 772 × 10⁶ BB̅ events, recorded at the ϒ(4S) resonance …

Source Evaluation Strategies For The Misinformation Age, Allison I. Faix

South Carolina Libraries

This article provides a summary of recent criticisms of checklist approaches to source evaluation to build a fuller picture of the issues involved with relying on checklists and factors that have increased the complexity of evaluating sources in the misinformation age. It then looks at new source evaluation strategies and methods which can be used by teachers and librarians to better prepare students for the internet realities they now face in their academic and personal online research.

Improved Bounds On Lorentz Symmetry Violation From High-Energy Astrophysical Sources, Brett David Altschul

Faculty Publications

Observations of the synchrotron and inverse Compton emissions from ultrarelativistic electrons in astrophysical sources can reveal a great deal about the energy–momentum relations of those electrons. They can thus be used to place bounds on the possibility of Lorentz violation in the electron sector. Recent 𝛾 -ray telescope data allow the Lorentz-violating electron 𝑐^𝜈𝜇 parameters to be constrained extremely well, so that all bounds are at the level of 7×10⁻¹⁶ or better.

The Malina Oceanographic Expedition: How Do Changes In Ice Cover, Permafrost And Uv Radiation Impact Biodiversity And Biogeochemical Fluxes In The Arctic Ocean?, Philippe Massicotte, Rainer M.W.

The MALINA oceanographic campaign was conducted during summer 2009 to investigate the carbon stocks and the processes controlling the carbon fluxes in the Mackenzie River estuary and the Beaufort Sea. During the campaign, an extensive suite of physical, chemical and biological variables were measured across seven shelf-basin transects (south-north) to capture the meridional gradient between the estuary and the open ocean. Key variables such as temperature, absolute salinity, radiance, irradiance, nutrient concentrations, chlorophyll a concentration, bacteria, phytoplankton and zooplankton abundance and taxonomy, and carbon stocks and fluxes were routinely measured onboard the Canadian research icebreaker CCGS Amundsen and from a …

A Case Examination Of Factors Impacting Charges In Vehicular Heatstroke, Jennifer Gray, Monica L. Mccoy

SC Upstate Research Symposium

Abstract — Since the 1990s, preventing vehicular heatstroke has been the focus of many public health campaigns. Parents are implored to never leave their young children unattended in the car, and to check the backseat before getting out of the car. Despite the increase in awareness about child fatalities due to hyperthermia, children continue to be left or forgotten in vehicles with tragic consequences. Interestingly, the decision to charge the negligent caregiver in cases of vehicular heatstroke is not widely studied. While some evidence indicates that case factors (e.g., intentionality and caregiver intoxication) are relevant in the decision to charge …

Background

Diet is a modifiable risk factor that may influence cognition in people with HIV.

Objectives

We examined the association between dietary intake and cognition in women with HIV (WWH) and HIV-seronegative women.

Methods

An 18-item dietary National Cancer Institute screener was completed by 729 WWH and 346 HIV-seronegative Women's Interagency HIV Study participants. Daily intake frequencies of processed meats, sweet beverages, fish, whole milk, and vegetables were calculated. Participants completed biennial neuropsychological (NP) testing. NP domains included attention/working memory, executive function, processing speed, memory, learning, fluency, and motor function. NP impairment was defined as demographically adjusted T-scores (mean = …

Maternal Pragmatic Language Difficulties In The Fmr1 Premutation And The Broad Autism Phenotype: Associations With Individual And Family Outcomes, Jessica Klusek, Angela John Thurman, Leonard Abbeduto

Faculty Publications

Broader phenotypes associated with genetic liability, including mild difficulties with pragmatic language skills, have been documented in mothers of children with autism spectrum disorder (ASD) and mothers of children with fragile X syndrome (FXS). This study investigated the relationship between pragmatic difficulties and indicators of maternal well-being and family functioning. Pragmatic difficulty was associated with loneliness in mothers of children with ASD or FXS, and with depression, decreased life satisfaction, and poorer family relationship quality but only in mothers of children with FXS. Results suggest that subtle maternal pragmatic language difficulties are a risk factor that that may contribute to …

An Evaluation Of The Sustainability Of The Palm Oil Industry, Leah Marie Roberts

Senior Theses

The goal of this thesis is to critically analyze the sustainability of the rapidly growing palm oil industry in order to diagnose whether the benefits of production outweigh the varied costs incurred by stakeholders, how the industry can be improved, and what analytical tools consumers can use to make better purchasing decisions. The body of the thesis begins with a discussion on sustainability definitions and determines that for this paper, sustainability will be defined as analyzing the socioeconomic and environmental effects of palm oil and how they affect different actors of the value chain in order to allow for prescriptions …

The Eviction Landscape In South Carolina, Ethan Magnuson

Senior Theses

The purpose of this thesis is to describe and analyze the South Carolinian eviction crisis from the perspective of radical geography. South Carolina was chosen for the severity of its crisis and the lack of research at a sub-state level. Court records of eviction filings from 2019 were geocoded and tested for spatial clustering, which was clearly visible. Plaintiff names were used to identify the most frequent filers and distinguish landlords by type. At the census tract level, eviction filing counts were compared with neighborhood characteristics using negative binomial regression, and most were found to be significant in South Carolina. …

An Overview Of Unethical Medical Practice In The United States And Their Implications, Virginia Scott

Senior Theses

Questionable and unethical medical experiments have existed and persisted since the creation of the field of medicine. In the 20^thcentury, the United States was a nation that acted as though they were the moral police and ultimate judges on humanitarian crisis such as unethical medical experiments. In reality, the United States was performing and endorsing unethical medical practices, as well as creating and funding the entire pseudoscience of eugenics, at the same time they were condemning others for doing so. The subsequent “codes of ethics” that were created allowed for the continuation of unethical practices throughout the 20 …
