Meeting Students Where They Are: Trauma-Informed Approaches In Rural Schools, Maria Frankland

The Rural Educator

Twenty-five percent of U.S. schoolchildren attend a rural school. Yet, rural school issues are typically subsumed by debates focused on urban problems and the misguided notion of ample resources available for their remediation. These assumptions belie the reality of the spatial mismatch that exists for rural schools, especially around mental health supports. Adverse childhood experiences and trauma disproportionately affect rural schoolchildren, putting them at greater risk of academic underachievement and other negative throughout the lifespan. Trauma-informed approaches in rural schools may mitigate the effects of childhood adversity and help close achievement gaps for rural students. Rural schools and students have …

Publications and Research

The novel COVID-19 outbreak is a major public health challenge that quickly turned into an economic recession of great proportions. This pandemic poses a trade-off between health and the economy where social distancing, quarantines, and isolation shut down demand and supply chains across the USA. This paper analyzes the impact of COVID-19 on illness and death among older adults and communities of color with low socioeconomic status in New York City. To achieve this goal, fractional logit models are used to capture changes in the novel virus’ morbidity and mortality rates at the neighborhood level. Median income, race/ethnicity, age, household …

Effects Of Salts On Structural, Physicochemical And Rheological Properties Of Low-Methoxyl Pectin/Sodium Caseinate Complex, Shengyu Fan, Fang Fang, Ailing Lei, Jiong Zheng, Fusheng Zhang

Department of Food Science Faculty Publications

The addition of salts is an effective way to improve the properties of polysaccharide/protein complexes for use in foods. However, there is no comparative study on the effects of different ions on the complex system of low methoxyl pectin (LMP)/ sodium caseinate (CAS) complex. The effects of different concentrations of three salt ions (Na⁺, K⁺, Ca²⁺) on the physicochemical and rheological properties of the LMP/CAS complex were determined in this study, and the structure of LMP/CAS complex was characterized. The results showed that the addition of these three salt ions affected zeta potential, particle …

The Earth–ionosphere cavity resonator is occupied primarily by the electromagnetic radiation of lightning below 100 Hz. The phenomenon is known as Schumann resonances (SR). SR intensity is an excellent indicator of lightning activity and its distribution on global scales. However, long-term measurements from high latitude SR stations revealed a pronounced in-phase solar cycle modulation of SR intensity seemingly contradicting optical observations of lightning from satellite, which do not show any significant solar cycle variation in the intensity and spatial distribution of lightning activity on the global scale. The solar cycle-modulated local deformation of the Earth–ionosphere cavity by the ionization of …

The Potential Of “Civic Science Education”: Theory, Research, Practice, And Uncertainties, Brett Levy, Alandeon Oliveira, Cornelia Harris

Educational Theory and Practice Faculty Scholarship

This paper explores the potential of civic science education (CSE), which includes experiences that have been intentionally designed to foster or enhance individuals’ interactions with and/or engagement in science‐related public matters. To begin, we provide a theoretically‐ grounded definition of CSE, including three sub‐categories: foundational, exploratory, and purposefully
active. We then explore the scholarly arguments for why enacting CSE could help to support students’ science learning and civic engagement and also strengthen civil society. Next, the paper examines current educational practices related to CSE, such as citizen science, exploring socioscientific issues, and various civic education pedagogies, detailing what researchers have …

Smartphone Appropriation And Knowledge Retention In Technology-Mediated Learning, Daniel Dwomor, Gamel O. Wiredu

African Conference on Information Systems and Technology

Digitization of learning activities has introduced some notable improvements as well as some significant knowledge retention impairments. Extant theories of knowledge retention are dominated by instrumental and cognitive approaches. Relatively less attention has been paid to the smartphone appropriation which includes instrumental and cognitive approaches but transcends them. This research adopts the smartphone appropriation approach to model antecedents of knowledge retention in the context of technology-mediated learning. It synthesizes user-invited actions based on technology design, knowledge retention, looping, and unlearning. The data analysis and model testing primarily confirm smartphone appropriation in knowledge retention. Complexity of technology usage in itself does …

Enhancing The Fertilizer Value Of Cattle Manure Using Organic Resources For Soil Fertility Improvement: A Review, Benedicta E. Ayamba, Robert C. Abaidoo, Andrews Opoku, Nana Ewusi-Mensah

Journal of Bioresource Management

The poor quality of cow dung in Ghana resulting from the opportunistic feeding mode of cattle impedes its adoption due to high quantities needed for application. This calls for nutrient optimization of cattle manure with inexpensive locally available sources of organic inputs that could enhance its quality. Though large volumes of crop residues and other agro-wastes are produced on-farm, they are underutilized and mostly a nuisance. Major food crops take approximately, 44 %, 42 % and 56 % of the total nitrogen (N), phosphorus (P) and potassium (K), respectively and are found in crop residues. There is therefore the need …

Microbial Activity Responses To Water Stress In Agricultural Soils From Simple And Complex Crop Rotations, Jorg Schnecker, D. Boone Meeden, Francisco Calderon, Michel Cavigelli, R. Michael Lehman, Lisa K. Tiemann, A. Stuart Grandy

Faculty Publications

Increasing climatic pressures such as drought and flooding challenge agricultural systems and their management globally. How agricultural soils respond to soil water extremes will influence biogeochemical cycles of carbon and nitrogen in these systems. We investigated the response of soils from long-term agricultural field sites under varying crop rotational complexity to either drought or flooding stress. Focusing on these contrasting stressors separately, we investigated soil heterotrophic respiration during single and repeated stress cycles in soils from four different sites along a precipitation gradient (Colorado, MAP 421 mm; South Dakota, MAP 580 mm; Michigan, MAP 893 mm; Maryland, MAP 1192 mm); …

BACKGROUND: Sleep-disordered breathing is a common disorder associated with significant morbidity. The genetic architecture of sleep-disordered breathing remains poorly understood. Through the NHLBI Trans-Omics for Precision Medicine (TOPMed) program, we performed the first whole-genome sequence analysis of sleep-disordered breathing.

METHODS: The study sample was comprised of 7988 individuals of diverse ancestry. Common-variant and pathway analyses included an additional 13,257 individuals. We examined five complementary traits describing different aspects of sleep-disordered breathing: the apnea-hypopnea index, average oxyhemoglobin desaturation per event, average and minimum oxyhemoglobin saturation across the sleep episode, and the percentage of sleep with oxyhemoglobin saturation < 90%. We adjusted for age, sex, BMI, study, and family structure using MMSKAT and EMMAX mixed linear model approaches. Additional bioinformatics analyses were performed with MetaXcan, GIGSEA, and ReMap.

RESULTS: We identified a …

Multivariate Analysis Of 1.5 Million People Identifies Genetic Associations With Traits Related To Self-Regulation And Addiction, Richard Karlsson Linnér, Travis T. Mallard, Peter B. Barr, Sandra Sanchez-Roige, James W. Madole, Morgan N. Driver, Holly E. Poore, Ronald De Vlaming, Andrew D. Grotzinger, Mark Z. Kos

School of Medicine Publications

Behaviors and disorders related to self-regulation, such as substance use, antisocial behavior and attention-deficit/hyperactivity disorder, are collectively referred to as externalizing and have shared genetic liability. We applied a multivariate approach that leverages genetic correlations among externalizing traits for genome-wide association analyses. By pooling data from ~1.5 million people, our approach is statistically more powerful than single-trait analyses and identifies more than 500 genetic loci. The loci were enriched for genes expressed in the brain and related to nervous system development. A polygenic score constructed from our results predicts a range of behavioral and medical outcomes that were not part …

Cfd Analysis Of Subcutaneous Deposition And Dispersion Of Insulin In Adipose Tissue, Ryan C. Lubbers

Masters Theses

Drug delivery is the most important factor of many therapies, but a lack of technology and research have led to a very generalized understanding of drug kinetics. Insulin pump therapy for the treatment of Type 1 Diabetes depends on precise delivery of the hormone into the adipose region between the dermis and underlying muscle. The kinetics of insulin within the adipose tissue environment is not well understood and varies greatly case to case. The use of computation fluid dynamics (CFD) models to study insulin kinetics in relation to influential factors will lead to a better understanding of the characteristics of …

Representation Justice As A Research Agenda For Socio-Hydrology And Water Governance, Melissa Haeffner, Dana E. Hellman, Alida Cantor, Idowu Ajibade, Vinka Oyanedel-Craver, Maura Kelly, Laura Schifman, Lisa Weasel

Environmental Science and Management Faculty Publications and Presentations

We propose representation justice as a theoretical lens for socio-hydrology and water governance studies. An exploratory survey of 496 water sector employees in the United States revealed that self-identifying females felt more strongly discriminated against due to their gender and other social factors, compared to self-identifying males. Responses unveiled how macro- and microaggressions impede career pathways to leadership positions and, therefore, representation. We identify ways in which socio-hydrology can benefit from a representation justice lens by considering the following: (1) how power and politics shape the composition of the water sector and decision-making processes; (2) how available quantitative data do …

Allelopathic Influence Of Eragrostis Curvula Water Extract On Seed Germination And Seedling Growth Of Two Other Species, R. W. Coelho, R. E. Schmidt

Effect Of Aging In Tillers Of Panicum Maximum On Leaf Elongation Rate, D. D. Carvalho, C. Matthew, J. Hodgson

IGC Proceedings (1977-2023)

Two cultivars of Guinea grass (P. maximum, Jacq.), Mombaça and Tanzânia, were cultivated in five litre pots, as single plants, in a green house. Plants were subjected to three defoliation levels (100, 200 and 400 mm height) for five successive monthly harvests. The experimental design was a 3x2 randomised block with five replicates. Three types of tiller (main, primary and secondary) were selected, at random, on each plant and leaf elongation rate (LER) above cutting height was measured, weekly, between harvests. There were significant differences (P < 0.05) in LER between tiller types in cv. Mombaça in all periods, but only in period two in cv. Tanzânia. In the last period tillers were classified, at random, as old (over four months age) mature (between two and four months) and young (between one and two months). Old tillers had a lower (P < 0.05) LER than the other two categories in both cultivars and lower (P < 0.05) SLA (specific leaf area) in Mombaça.

Dormant Bud Development In Phalaris Aquatica L., Brendan R. Cullen, P. E. Quigley, D. F. Chapman

IGC Proceedings (1977-2023)

The formation of dormant buds is critical to the summer survival of phalaris (Phalaris aquatica L.) in pastures. Dormant buds are formed on the base of reproductive tillers as they develop in spring. This project aimed to determine the seasonal pattern of dormant bud development and the influence of grazing management on bud dynamics. Approximately three buds per reproductive tiller were formed in the spring and early summer period. These buds responded to summer rainfall, with one third of buds becoming active following a 15-mm rainfall event in mid summer. In the following growing season, on average, 1.5 buds …

Tillering Dynamics Of Panicum Maximum Jacq. Cv. Tanzania-1 After Grazing, Rodrigo A. Barbosa, Domicio Nascimento Jr., Valéria P. B. Euclides, A. J. Regazzi, D. M. Fonseca

IGC Proceedings (1977-2023)

Tillering dynamics and tiller dry matter weight from Tanzania grass (Panicum maximum cv. Tanzania-1) were evaluated in two post-grazing stubbles (High Post-grazing Stubble – HPS-3.6 t of DM/ha and Low Post-grazing Stubble – LPS-2.3 t of DM/ha). There was no difference between post-grazing stubbles for decapitated axillary and basal remainder and new axillary tillers. The LPS presented greater number of new basal tillers. The rate of appearance of new basal and axillary tillers decreased with time after grazing. There were differences between the treatments on tiller dry matter weight, and greater values were found in the high post-graze stubble.

Konjac Glucomannan Polysaccharide And Inulin Oligosaccharide Ameliorate Dextran Sodium Sulfate-Induced Colitis And Alterations In Fecal Microbiota And Short-Chain Fatty Acids In C57bl/6j Mice, Chih-Hsuan Changchien, Cheng-Hsin Wang, Hsiao-Ling Chen
