Effect Of Bulk Composition On The Heterogeneous Oxidation Of Semi-Solid Atmospheric Aerosols, Hanyu Fan, Fabien Goulay

Faculty & Staff Scholarship

Abstract: The OH-initiated heterogeneous oxidation of semi-solid saccharide particles with varying bulk compositions was investigated in an atmospheric pressure flow tube at 30% relative humidity. Reactive uptake coefficients were determined from the rate loss of the saccharide reactants measured by mass spectrometry at different monosaccharide (methyl-β-d-glucopyranoside, C7H14O6) and disaccharide (lactose, C12H22O11) molar ratios. The reactive uptake for the monosaccharide was found to decrease from 0.53 ± 0.10 to 0.05 ± 0.06 as the mono-to-disaccharide molar ratio changed from 8:1 to 1:1. A reaction–diffusion model was developed in order to determine the effect of chemical composition on the reactive uptake. The …

Can Religiosity Be Explained By ‘Brain Wiring’? An Analysis Of Us Adults’ Opinions, Sharan Kaur Mehta, Christopher P. Scheitle, Elaine Howard Ecklund

Faculty & Staff Scholarship

Studies examining how religion shapes individuals’ attitudes about science have focused heavily on a narrow range of topics, such as evolution. This study expands this literature by looking at how religion influences individuals’ attitudes towards the claim that neuroscience, or “brain wiring,” can explain differences in religiosity. Our analysis of nationally representative survey data shows, perhaps unsurprisingly, that religiosity is negatively associated with thinking that brain wiring can explain religion. Net of religiosity, though, individuals reporting religious experiences are actually more likely to agree that brain wiring can explain religiosity, as are individuals belonging to diverse religious traditions when compared …

Father-Daughter Incest: Comparison Of Treated Cases To Untreated Control Subjects, Keith W. Beard, Jason E. Newsome, Karen V. Harper-Dorton, Stephen L. O'Keefe, Debra H. Young, Sam Swindell, Walter E. Stroupe, Kerri Steele, Megan Lawhon, Shih-Ya Kuo

Faculty & Staff Scholarship

Treatment of father daughter incest (FDI) survivors using the victim advocacy/child welfare approach to FDI that predominates today in the US has never been compared to results in untreated control subjects in any published report. In the present study, thirty-two survivors of FDI who received treatment based on the victim advocacy/child welfare approach to FDI were compared to 32 control subjects who did not receive treatment. No significant differences were found using analysis of variance on 21 scales and subscales. Statistical analysis of the data from all 64 of the FDI survivors showed that items reflecting a poor self-image and …

A Data Envelopment Analysis Of West Virginia School Districts, Eduardo Minuci, Amir B. Ferreira Neto, Joshua Hall

Faculty & Staff Scholarship

West Virginia schools are consistently below the national average on the National Assessment of Educational Progress. Using Data Envelopment Analysis, we estimate the technical efficiency of West Virginia school districts. We find less variation in technical efficiency in West Virginia than in similar studies conducted in other states. This appears to be because of state policy imposing homogeneity of input usage. Due to the limited variation in technical efficiency across districts, we cannot analyze how non-school inputs such as socioeconomic factors affect technical efficiency across districts. Summary statistics organized by county economic status, however, suggest that socioeconomic status plays a …

Modelling And Evaluation Of Electrical Resonance Eddy Current For Submillimeter Defect Detection, Yew San Hor, Vinod K. Sivaraja, Yu Zhong, Bui V. Phuong, Christopher Lane

Physics Faculty Research & Creative Works

Eddy current (EC) inspection is used extensively in non-destructive testing (NDT) to detect surface-breaking defects of engineering components. However, the sensitivity of conventional eddy current inspection has plateaued in recent years. The ability to detect submillimetre defects before it becomes critical would allow engineering components to remain in-service safely for longer. Typically, it is required that higher frequency EC is employed to achieve a suitable sensitivity for detection of such submillimetre defects. However, that would lead to significant electromagnetic noise affecting the sensitivity of the inspection. To overcome this issue, the electrical-resonance based eddy current method has been proposed, where …

Faculty & Staff Scholarship

Bamboo shoots, a promising renewable biomass, mainly consist of carbohydrates and other nitrogen-related compounds, such as proteins, amino acids and nucleotides. In this work, nitrogen self-doped activated carbons derived from bamboo shoots were prepared via a simultaneous carbonization and activation process. The adsorption properties of the prepared samples were evaluated by removing methylene blue from waste water. The factors that affect the adsorption process were examined, including initial concentration, contact time and pH of methylene blue solution. The resulting that BSNC-800-4 performed better in methylene blue removal from waste water, due to its high specific surface area (2270.9 m2 g−1), …

Characterizing Land Use Impacts On Channel Geomorphology And Streambed Sedimentological Characteristics, Sean J. Zeiger, Jason A. Hubbart

Faculty & Staff Scholarship

Land use can radically degrade stream physical habitat via alterations to channel geomorphology and sedimentological characteristics. However, independent and combined influences such as those of agricultural and urban land use practices on channel geomorphology and substrate composition remain poorly understood. To further understanding of mixed land use influence on stream physical habitat, an intensive, 56 km hydrogeomorphological assessment was undertaken in a representative mixed land use watershed located in Midwestern USA. Sub-objectives included quantitative characterization of (1) channel geomorphology, (2) substrate frequency and embeddedness, and (3) relationships between land use, channel geomorphology, and substrate frequency and embeddedness. Channel geomorphology, and …

Apoa-I Deficiency Increases Cortical Amyloid Deposition, Cerebral Amyloid Angiopathy, Cortical And Hippocampal Astrogliosis, And Amyloid-Associated Astrocyte Reactivity In App/Ps1 Mice, Emily B. Button, Guilaine K. Boyce, Anna Wilkinson, Sophie Stukas, Arooj Hayat, Jianjia Fan, Brennan J. Wadsworth, Jerome Robert, Kris M. Martens, Cheryl L. Wellington

Faculty & Staff Scholarship

Background

Alzheimer’s disease (AD) is defined by amyloid beta (Aβ) plaques and neurofibrillary tangles and characterized by neurodegeneration and memory loss. The majority of AD patients also have Aβ deposition in cerebral vessels known as cerebral amyloid angiopathy (CAA), microhemorrhages, and vascular co-morbidities, suggesting that cerebrovascular dysfunction contributes to AD etiology. Promoting cerebrovascular resilience may therefore be a promising therapeutic or preventative strategy for AD. Plasma high-density lipoproteins (HDL) have several vasoprotective functions and are associated with reduced AD risk in some epidemiological studies and with reduced Aβ deposition and Aβ-induced inflammation in 3D engineered human cerebral vessels. In mice, …

Controlling The Transverse Proton Relaxivity Of Magnetic Graphene Oxide, Bibek Thapa, Daysi Diaz-Diestra, Dayra Badillo-Diaz, Rohit Kumar Sharma, Kiran Dasari, Shalini Kumari, Mikel B. Holcomb, Juan Beltran-Huarac, Brad R. Weiner, Gerardo Morell

Faculty & Staff Scholarship

The engineering of materials with controlled magnetic properties by means other than a magnetic feld is of great interest in nanotechnology. In this study, we report engineered magnetic graphene oxide (MGO) in the nanocomposite form of iron oxide nanoparticles (IO)-graphene oxide (GO) with tunable core magnetism and magnetic resonance transverse relaxivity (r2). These tunable properties are obtained by varying the IO content on GO. The MGO series exhibits r2 values analogous to those observed in conventional single core and cluster forms of IO in diferent size regimes—motional averaging regime (MAR), static dephasing regime (SDR), and echo-limiting regime (ELR) or slow …

How Can Cities Respond To Flood Disaster Risks Under Multi-Scenario Simulation? A Case Study Of Xiamen, China, Yijun Shi, Guofang Zhai, Shutian Zhou, Yuwen Lu, Wei Chen, Jinyang Deng

Faculty & Staff Scholarship

Flood disasters often have serious impacts on cities. Disaster prevention and mitigation schemes for flood disasters must be based on risk assessment. We constructed an indicator system for flood disaster risk assessment from the aspects of hazard factors, sensitivity to the environment, disaster vulnerability, flood disaster prevention, and resilience. Then we add the precipitation factor as a scenario parameter to the assessment of flood disasters, in order to assess the flood disaster risk under annual average precipitation scenarios, multi-year flood season average precipitation scenarios, and large typhoon precipitation scenarios. Xiamen is one of the cities with more serious flood disasters. …

Short Rotation Wood Crops In Latin American: A Review On Status And Potential Uses As Biofuel, Roger Moya, Carolina Tenorio, Gloria Oporto

Faculty & Staff Scholarship

Studies related to biomass production, with a focus on energy uses for short-rotation woody crops (SRWCs), are limited in Latin America. The research that is available relates to a variety of tested SRWC species (50 species), however, the most important species are Populus, Salix, Eucalyptus, Acacia, and Gmelina arborea. In the existing studies, stocking densities varied from 1111 to 20,000 trees per hectare, with square or rectangular spacing. One important advantage of SRWC systems in this region, compared to most regions worldwide, is the predictability of biomass yields due to the tropical climate conditions of the majority of the Latin …

Technology-Facilitated Stalking And Unwanted Sexual Messages/Images In A College Campus Community: The Role Of Negative Peer Support, Walter D. Dekeseredy, Martin D. Schwartz, Bridget Harris, Delanie Woodlock, James Nolan, Amanda Hall-Sanchez

Faculty & Staff Scholarship

Researchers have accumulated much social scientific knowledge about the scope, distribution, causes, and outcomes of the physical and sexual abuse of female students in North American institutions of higher learning. However, surveys of technology-facilitated stalking and the dissemination of unwanted sexual messages/images in college campus communities are in short supply. The few that have been conducted do not identify key sociological risk factors associated with these two electronic forms of victimization. This paper, then, has two objectives: (1) to examine the influence of two types of negative peer support and (2) to determine if being the target of technology-facilitated stalking …

Reconceptualizing Attrition In Parent–Child Interaction Therapy: “Dropouts” Demonstrate Impressive Improvements, Corey C. Lieneman, Lauren B. Quetsch, Laurie L. Theodorou, Kathleen A. Newton, Cheryl B. Mcneil

Faculty & Staff Scholarship

Purpose: Behavior disorders in early childhood are linked to a variety of negative outcomes for both children and families. Parent–Child Interaction Therapy (PCIT), an evidence-based parent-training program, demonstrates large effect sizes in reducing child problem behavior for dyads who complete treatment; however, a high number of families seeking treatment in community-based settings terminate from PCIT prior to meeting the protocol’s strict graduation criteria. The purpose of this study was to examine the impact of PCIT on child behavior problems for families who received at least a small dose of PCIT but not enough to meet the strict mastery criteria required …

Teacher Shortage As A Local Phenomenon: District Leader Sensemaking, Responses, And Implications For Policy, Erin Mchenry-Sorber, Matthew P. Campbell

Faculty & Staff Scholarship

While the teacher shortage is a national crisis, the manifestations of the shortage are felt most acutely at the local district level. The diversity of these micro-contexts often leads to disparities in the ways local school systems are served by large-scale initiatives. District leaders provide an important lens for understanding the localized manifestation of teacher shortages. This research contributes to the existing macro-level literature on teacher shortages through investigation of the ways in which district leaders in West Virginia make sense of and respond to the teacher shortage. As part of a broader study, we share analyses of interviews with …

Overview: Cardiovascular disease remains a leading cause of death worldwide, with vulnerable plaque rupture the underlying cause of many heart attacks and strokes. Much research is focused on identifying an imaging biomarker to differentiate stable and vulnerable plaque. Magnetic Resonance Imaging (MRI) is a non-ionising and non-invasive imaging modality with excellent soft tissue contrast. However, MRI has relatively low sensitivity (micromolar) for contrast agent detection compared to nuclear imaging techniques. There is also an increasing emphasis on developing MRI probes that are not based on gadolinium chelates because of increasing concerns over associated systemic toxicity and deposits1. To address the …

A Framework For Understanding The Role Of Psychological Processes In Disease Development, Maintenance, And Treatment: The 3p-Disease Model, Casey D. Wright, Alaina Tiani, Amber Lynn Billingsley, Shari Alaina Steinman, Kevin T. Larkin, Daniel W. Mcneil

Faculty & Staff Scholarship

Health psychology is multidisciplinary, with researchers, practitioners, and policy makers finding themselves needing at least some level of competency in a variety of areas from psychology to physiology, public health, and others. Given this multidisciplinary ontology, prior attempts have been made to establish a framework for understanding the role of biological, psychological, and socio-environmental constructs in disease development, maintenance, and treatment. Other models, however, do not explain how factors may interact and develop over time. The aim here was to apply and adapt the 3P model, originally developed and used in the treatment of insomnia, to couch the biopsychosocial model …
