Libraries On The Front Lines: The Imperative For Disaster-Ready Information Professionals, Feili Tu-Keefner Ph.D.
Faculty Publications
Libraries, particularly local public libraries, have evolved into hubs for community-first services, extending beyond traditional roles. Library personnel are now expected to act as first responders and crisis leaders during times such as natural disasters. This report documents the critical crisis leadership qualifications required for library personnel, identified through comprehensive research from 2015 to 2023. Findings from these situation-specific case studies call attention to the community’s needs for library services during emergencies, underscoring the requirement for LIS education to include disaster management. Continuing education (CE) is also critical in preparing information professionals for these essential roles.
How Should Scientists Act? Assessing Public Perceptions Of Scientists And Scientific Practices And Their Implications For Science Communication, Thomas G. Safford, Emily H. Whitmore
How Should Scientists Act? Assessing Public Perceptions Of Scientists And Scientific Practices And Their Implications For Science Communication, Thomas G. Safford, Emily H. Whitmore
Faculty Publications
Is how science is conducted legitimate? Are scientists trustworthy? Whether the public answers “yes” to these questions is critical for science communicators. We explore how social factors affect public perceptions of the practice of science, and then test how those beliefs relate to views about how scientists engage with the public and policy making. Our results show that political ideology and religiosity affect these views. However, more importantly, respondents’ concerns about the integrity of the scientific process are the strongest predictor of views about scientists’ behavior, providing a focus area for future communication efforts in support of science-based decision making.

Charging, Aggregation, And Electrostatic Dispersion Of Radioactive And Nonradioactive Particles In The Atmosphere, Yong Ha Kim, Sotira Yiacoumi, Costas Tsouris
Faculty Publications
Electrostatic dispersion can significantly impact the microphysical behavior of charged particles and ions until reaching zero space charge. However, although radioactive particles can be strongly charged in air, the influence of electrostatic dispersion has been neglected in understanding their behavior. This study is aimed at investigating the time evolution of the charge and size distributions of radioactive and nonradioactive particles in air and developing simple approaches for applications. With processes involving charging, aggregation, and electrostatic dispersion, a comprehensive population balance model (PBM) has been developed to examine particle charge/size distribution dynamics. It is shown that compared to nonradioactive particles, the …

The Impacts Of Co-Occurring Developmental Language Disorder On The Academic, Interpersonal, And Behavioral Profiles Of Children With Adhd, Kirsten M. Hannig Russell, Sean M. Redmond
Faculty Publications
Purpose: Attention-deficit/hyperactivity disorder (ADHD) is a multifactorial disorder that has been linked to increased risk for behavioral, academic, and interpersonal problems. Developmental language disorder (DLD) has also been linked to poor outcomes in these areas. The presence of co-occurring disorders in children’s profiles is generally associated with poorer outcomes relative to profiles consisting of only one disorder. This study investigated the extent to which co-occurring DLD in children already identified with ADHD presented increased risk for severity of their primary ADHD symptoms, the presence of secondary behavioral problems, and/or increased problems in the tertiary areas of academic performance and interpersonal …

The availability of natural resources drives the exploration and transformation of remote regions in the Arctic and beyond. Extractive infrastructure is one of the major sources of industrial development and environmental impact on landscapes. For Indigenous people, these landscapes are homely environments full of sentient beings, and for other local communities, they provide a wide variety of subsistence and hunting resources. While extractive infrastructure violence is the evident issue for many Indigenous communities, there are more complicated situations where extractive infrastructure is adopted and utilized for the subsistence and support of other human and more-than-human relations in local and Indigenous …
Everyone Brings Something To The Table: A Culturally Sustaining Analysis Of Teacher Candidates’ Mixed Reality Teaching Simulations, Erin Scott
Faculty Publications
Discussions of HBCU students’ content knowledge have centered around developing high impact, asset-based approaches to learning (Williams et al, 2022). So, HBCU teacher preparation providers (TPPs) can also focus efforts on culturally sustaining approaches to developing candidates’ content knowledge and researching how high impact practices, like teaching simulations, can help prepare candidates for classrooms. This exploratory case study uses critical cases (n=2); findings suggest candidates have a developing understanding of content, which forms a solid basis for increasing their knowledge. MRTSs are addressed as a potential high impact, culturally sustaining practice for building candidates’ content knowledge. Further, HBCU TPPs can …

Coastal wetlands are one of the most productive ecosystems on Earth with the capacity to sequester large amounts of carbon dioxide (CO2). Wetland loss due to anthropogenic and natural causes reduces the carbon (C) storage capacity and potentially releases previously fixed C in biomass and soil to the water column and atmosphere through decomposition. Coastal wetland restoration has the potential to mitigate some of the C losses depending on the balance of C fluxes. However, the role of vegetation and environmental conditions in governing rates of C accumulation in restoration sites is not well resolved. The purpose of this study …

Although mangroves provide many beneficial ecosystem services, such as blue carbon storage and coastal protection, they are currently under threat due to changes in climate conditions, such as prolonged drought exposure. Under drought conditions, evaporation exceeds precipitation and high soil salinities can lead to stunted growth and die-back. To quantify this interplay, we developed a database for low-lying and uninhabited mangrove islands in the Caribbean under various evaporation and precipitation regimes. We extracted physical and biological information from each island using remote sensing techniques and coupled it with a process-based model. We used this database to develop a model that …

There is an urgent need for models that can robustly detect past and project future ecosystem changes and risks to the services that they provide to people. The Fisheries and Marine Ecosystem Model Intercomparison Project (FishMIP) was established to develop model ensembles for projecting long-term impacts of climate change on fisheries and marine ecosystems while informing policy at spatio-temporal scales relevant to the Inter-Sectoral Impact Model Intercomparison Project (ISIMIP) framework. While contributing FishMIP models have improved over time, large uncertainties in projections remain, particularly in coastal and shelf seas where most of the world's fisheries occur. Furthermore, previous FishMIP climate …

Covid, Elite Rhetoric, And Americans’ Attitudes Toward U.S. Trade Practices With China, Dmitriy Nurullayev, Ping Xu, James Garand
Faculty Publications
Objectives: In this article, we consider how the COVID-19 pandemic and evaluations of Donald Trump combined to influence Americans' attitudes toward U.S. trade practices with China. We suggest that psychological factors—such as confirmation bias and transfer of grievances—influence how individuals evaluate the costs and benefits of trade. Specifically, we argue that the severity of the pandemic (reflected by both cumulative deaths and news coverage of the pandemic) and the rhetoric of (then) President Trump came together to influence Americans’ attitudes toward trade with China. Methods: To assess the COVID effect, the Trump effect, and their interaction effect on trade opinion, …

On The Identification And Use Of Social Versus Nonsocial Reinforcers: A Review Of Research Practices, Samuel L. Morris, Katherine G. Bridges
Faculty Publications
Recent research has developed efficacious methods for identifying individualized social reinforcers and utilizing social reinforcers may be beneficial for several reasons. However, the relative likelihood of utilizing social versus nonsocial reinforcers in behavior-analytic research remains unclear. The aim of this study was to evaluate how likely behavior analysts are to employ social versus nonsocial reinforcers in the context of research. We pursued this aim by evaluating the types of reinforcers utilized in research published during the past 9 years in five applied behavior-analytic journals. Results suggest that researchers in applied behavior analysis have been more likely to use individualized nonsocial …

A 2.1 yr periodic oscillation of the gamma-ray flux from the blazar PG 1553+113 has previously been tentatively identified in ∼7 yr of data from the Fermi Large Area Telescope. After 15 yr of Fermi sky-survey observations, doubling the total time range, we report >7 cycle gamma-ray modulation with an estimated significance of 4σ against stochastic red noise. Independent determinations of oscillation period and phase in the earlier and the new data are in close agreement (chance probability < 0.01). Pulse timing over the full light curve is also consistent with a coherent periodicity. Multiwavelength new data from Swift X-Ray Telescope, Burst Alert Telescope, and UVOT, and from KAIT, Catalina Sky Survey, All-Sky Automated Survey for Supernovae, and Owens Valley Radio Observatory ground-based observatories as well as archival Rossi X-Ray Timing Explorer satellite-All Sky Monitor data, published optical data of Tuorla, and optical historical Harvard plates data are included in our work. Optical and radio light curves show clear correlations with the gamma-ray modulation, possibly with a nonconstant time lag for the radio flux. We interpret the gamma-ray periodicity as possibly arising from a pulsational accretion flow in a sub-parsec binary supermassive black hole system of elevated mass ratio, with orbital modulation of the supplied material and energy in the jet. Other astrophysical scenarios introduced include instabilities, disk and jet precession, rotation or nutation, and perturbations by massive stars or intermediate-mass black holes in polar orbit.

The Arctic Ocean supports a unique and dynamic microbial community, yet its composition, structure, and response to environmental shifts remain incompletely understood. In this study, 16S rRNA gene metabarcoding (targeting the V3-V4 and V4-V5 hypervariable regions) was used to assess surface water microbial diversity across 20 stations in the Barents Sea, focusing on latitudinal variations within two contrasting current systems: the West Spitsbergen Current (WSC) and the East Spitsbergen Current (ESC). Our results showed that the microbial community is dominated by three primary families—Pseudoalteromonadaceae, Moraxellaceae, and Flavobacteriaceae (14.20%). Comparative analysis of the V3-V4 and V4-V5 regions reveals that each region …

Heavy and costly use of phosphorus (P) fertiliser is often needed to achieve high crop yields, but only a small amount of applied P fertiliser is available to most crop plants. Hakea prostrata (Proteaceae) is endemic to the P-impoverished landscape of southwest Australia and has several P-saving traits. We identified 16 members of the Phosphate Transporter 1 (PHT1) gene family (HpPHT1;1-HpPHT1;12d) in a long-read genome assembly of H. prostrata. Based on phylogenetics, sequence structure and expression patterns, we classified HpPHT1;1 as potentially involved in Pi uptake from soil and HpPHT1;8 and HpPHT1;9 as potentially involved in Pi uptake and root-to-shoot …

Abstract: Sugarcane (Saccharum officinarum) is Louisiana's number one row crop. Growing and processing sugarcane produces significant amounts of byproducts, including bagasse, crop residue, molasses, filter-press mud, and boiler fly ash. These products represent an important opportunity to generate value-added and specialty products and enhance sugarcane's sustainability by facilitating a circular economy, where agricultural by-products are reused instead of disposing them (linear economy), in order to reduce resource use and energy demand. Examples of value-added products range from biochar, construction materials, animal feed, biofuels, nanoparticles, and fertilizer. Paramount to the success of the bio-based circular economy is creating useful products that …

Winter injury can cause significant loss of hybrid bermudagrasses [Cynodon dactylon (L.) Pers. × C. transvaalensis Burtt-Davy] in the transition zone. Current research has focused on high-value, low-acreage areas like putting greens, but those practices are impractical to implement on golf course fairways. To that end, multi-year research projects were conducted at three sites across Maryland and Virginia to investigate the influence of annual N fertility [2.0 lb N 1000 ft−2 (early summer application) or 4.0 lb N 1000 ft−2 (split applied early and late summer)] across multiple fall mowing heights (0.5 inches, 0.8 inches, or 1 inch) and to …

Bermudagrass (Cynodon spp. Rich) is a warm-season grass that is widely planted throughout tropical, sub-tropical, and even temperate climates, and it generally requires fewer inputs than most cool-season turfgrasses. In recent years, the area of adaptation for bermudagrass has progressively expanded to cooler climates due to the development of more cold-tolerant cultivars. The expanded area of adaptation as well as the reduced inputs required to maintain healthy turfgrass have made bermudagrass a popular choice in areas of marginal adaptation. In these areas, the greatest threat to bermudagrass health and survivability is winterkill. This management guide seeks to describe winterkill: what …

Faculty Publications
Recently, a series of 8(meso)-pyridyl-BODIPYs (2-pyridyl, 3-pyridyl, and 4-pyridyl) and their 2,6-substituted derivatives were synthesized and their structure and photophysical properties were studied both experimentally and computationally. One of the main observed trends was that the 2-pyridyl-BODIPYs were consistently less fluorescent than their 3-pyridyl and 4-pyridyl analogs, regardless of the 2,6-substituents. Herein, we extend our previous computational studies and model not only the ground but also the excited states of the entire series of previously synthesized meso-pyridyl-BODIPYs with the aim of explaining the observed differences in the emission quantum yields. To better understand the trends and the effect of 2- …

The increased politicization of sexual and reproductive health has created barriers to medically necessary care. In absence of formal health care, social ties become critical sources of information and resources, yet the disclosure of stigmatized health needs carries significant risk. How do people navigate the risks and benefits of disclosure when seeking care for stigmatized needs? Drawing on original survey data (N = 153) and in-depth interviews (N = 55) with women who attempted a self-managed abortion, I first describe the distinct roles of weak and strong ties in women’s health-seeking experiences. I then demonstrate how both partial disclosure and …

The concentration of small molecules reflects the normality of physiological processes in the human body, making the development of simple and efficient detection equipment essential. In this work, inspired by a facile strategy in point-of-care detection, two devices were fabricated to detect small molecules via photocurrent measurement. A linear response of the photocurrent against the concentration of the small molecules was found. In the first device, metal ions were introduced into gel substrates made by xanthan gum to enhance photocurrent response. N-phenyl-2-naphthylamine was measured when iron or manganese ions were used. L-Phenylalanine was measured when the gel was modified by …

Nano-delivery of natural compounds has gained increasing attention in the food and pharmaceutical ingredients industry. Avocado seed was extracted by a total lipid extraction and the presence of two acetogenin compounds was confirmed by the high-performance liquid chromatography (LC-MS) technique. Then, the avocado seed extract (Avo) was encapsulated into zein nanoparticles by liquid-liquid dispersion and the formation of zein nanoparticles loaded with avocado seed extract (Avo-ZNPs) was confirmed by FTIR analysis. The Avo-ZNPs with various Avo contents showed an average size ranging from 166.9 ± 14.1 to 305.2 ± 16.2 nm with 0.19–0.26 of polydispersity index (PDI), and a surface …

In the United States, the nineteenth century was the halcyon era for local newspapers. These publications were the primary source of public information at a time when other periodicals and books had low circulation. The purpose of this paper is to explore how local journalism in the nineteenth-century United States dealt with an occasion outside the boundaries of the commonplace: an unfamiliar natural phenomenon. My example is the total solar eclipse of 7 August 1869. Editors and journalists of the time largely were unaccustomed to covering celestial events. Nevertheless, they sensed—correctly—an interest in the solar eclipse. Articles about the approaching …
