Squirreling From Afar: Adapting Squirrel-Net Modules For Remote Teaching And Learning, Laurie Dizney, Johanna Varner, Jennifer Duggan, Hayley C. Lanier, Patrice K. Connors, Liesl P. Erb, Elizabeth A. Flaherty, Christopher J. Yahnke, John D. Hanson

AES Faculty Publications and Presentations

The shift from face-to-face instruction to remote teaching and learning has proven to be a challenging endeavor for many reasons, including lack of time, resources, and inspiration. Lab courses, the “hands-on” portion of many curricula, may be especially difficult to adapt to online learning given the common use of specialized equipment, materials, and techniques that require close supervision. Without the time and resources to creatively modify existing activities or create new ones, remote lab courses run the risk of becoming less effective, equitable, and/or engaging. Squirrel-Net has created four field-based activities for biology labs that are easy to implement, highly …

Implications Of Climate-Driven Fallowing For Ecological Connectivity Of Species At Risk, Sofie He Mccomb, Claire Powers, Forrest Melton, Ashley Larsen

AES Faculty Publications and Presentations

Context.

Climate change and agricultural intensification are modifying the configuration of natural lands within agricultural landscapes, further impacting species’ ability to move freely between remaining natural areas. These working landscapes have inherently high opportunity costs, making the establishment of additional permanent reserves for species movement unlikely.

Objectives.

Here we explore the potential for opportunistic and dynamic conservation reserves, in the form of temporary fallowed croplands, to increase connectivity in competing land use regions.

Methods.

We evaluate the potential for fallowed lands to facilitate habitat connectivity for at-risk species in the San Joaquin Valley (SJV), an intensive agricultural landscape in California. …

New Generation Geostationary Satellite Observations Support Seasonality In Greenness Of The Amazon Evergreen Forests, Hirofumi Hashimoto, Weile Wang, Jennifer L. Dungan, Shuang Li, Andrew R. Michaelis, Hideaki Takenaka, Atsushi Higuchi, Ranga B. Myneni, Ramakrishna R. Nemani

AES Faculty Publications and Presentations

Assessing the seasonal patterns of the Amazon rainforests has been difficult because of the paucity of ground observations and persistent cloud cover over these forests obscuring optical remote sensing observations. Here, we use data from a new generation of geostationary satellites that carry the Advanced Baseline Imager (ABI) to study the Amazon canopy. ABI is similar to the widely used polar orbiting sensor, the Moderate Resolution Imaging Spectroradiometer (MODIS), but provides observations every 10–15 min. Our analysis of NDVI data collected over the Amazon during 2018–19 shows that ABI provides 21–35 times more cloud-free observations in a month than MODIS. …

Flux-Data-Qaqc: A Python Package For Energy Balance Closure And Post-Processing Of Eddy Flux Data, John Volk, Justin Huntington, Richard Allen, Forrest Melton, Martha Anderson, Ayse Kilic

AES Faculty Publications and Presentations

Eddy Covariance (EC) systems provide continuous direct measurements of turbulent and radiative heat and energy fluxes between the atmosphere and land surface (Baldocchi et al., 1988). Evapotranspiration (ET) estimates from EC systems are highly valuable for many scientific disciplines, water policy decisions, and operational applications such as irrigation management. Although the EC technique is considered accurate under certain atmospheric and spatial conditions, inherent theoretical and practical limitations of the technique are magnified by data uncertainty from post-processing methods. Error can result from the well-documented energy balance closure problem resulting from inherent limitations in the technique but also from data processing …

Applied Machine Learning In Extrusion-Based Bioprinting, Shuyu Tian

Theses and Dissertations

Optimization of extrusion-based bioprinting (EBB) parameters have been systematically conducted through experimentation. However, the process is time and resource-intensive and not easily translatable across different laboratories. A machine learning (ML) approach to EBB parameter optimization can accelerate this process for laboratories across the field through training using data collected from published literature. In this work, regression-based and classification-based ML models were investigated for their abilities to predict printing outcomes of cell viability and filament diameter for cell-containing alginate and gelatin composite hydrogels. Regression-based models were investigated for their ability to predict suitable extrusion pressure given desired cell viability when keeping …

A Comprehensive Study To Delineate The Role Of An Extracellular Vesicle-Associated Microrna-29a In Chronic Methamphetamine Use Disorder, Subhash Chand, Austin Gowen, Mason Savine, Dalia Moore, Alexander Clark, Wendy Huynh, Niming Wu, Katherine Odegaard, Lucas Weyrich, Rick A. Bevins, Howard S. Fox, Gurudutt Pendyala, Sowmya V. Yelamanchili

Department of Psychology: Faculty Publications

Extracellular vesicles (EVs), which express a repertoire of cargo molecules (cf. proteins, microRNA, lipids, etc.), have been garnering a prominent role in the modulation of several cellular processes. Here, using both non-human primate and rodent model systems, we provide evidence that brain-derived EV (BDE) miRNA, miR- 29a-3p (mir-29a), is significantly increased during chronic methamphetamine (MA) exposure. Further, miR-29a levels show significant increase both with drug-seeking and reinstatement in a rat MA self-administration model. We also show that EVassociated miR-29a is enriched in EV pool comprising of small EVs and exomeres and further plays a critical role in MA-induced inflammation and …

Much Ado About Missingness: A Demonstration Of Full Information Maximum Likelihood Estimation To Address Missingness In Functional Magnetic Resonance Imaging Data, Timothy D. Nelson, Rebecca L. Brock, Sonja Yokum, Cara C. Tomaso, Cary R. Savage, Eric Stice

Department of Psychology: Faculty Publications

The current paper leveraged a large multi-study functional magnetic resonance imaging (fMRI) dataset (N = 363) and a generated missingness paradigm to demonstrate different approaches for handling missing fMRI data under a variety of conditions. The performance of full information maximum likelihood (FIML) estimation, both with and without auxiliary variables, and listwise deletion were compared under different conditions of generated missing data volumes (i.e., 20, 35, and 50%). FIML generally performed better than listwise deletion in replicating results from the full dataset, but differences were small in the absence of auxiliary variables that correlated strongly with fMRI task data. However, …

Internal Audit Stigma Impairs Internal Audit Outcomes, Marc Eulerich, Joleen Kremin, K. Kelli Saunders, David A. Wood

Faculty Publications

Prior research finds that the internal audit function (IAF) plays a critical role in organizations, yet there is still a stigma toward the profession. We examine how this stigma affects internal audit outcomes, using three different data sources: survey results from parts of Europe and the United States and an experiment. We find that when practicing internal auditors in parts of Europe and the U.S. believe there is a negative stigma about internal auditing, they report negative work outcomes, including less ability to add value, less influence in the organization, more resistance to implementing their recommendations, and more pressure to …

Getting It: The Ada After Thirty Years, Elizabeth F. Emens

Faculty Scholarship

On the thirtieth anniversary of the Americans with Disabilities Act (ADA), this essay examines the vital role that attitudes have played — and will play — in the success of this pathbreaking civil rights law. Drawing on the legacy of the late disability philosopher and bioethicist Adrienne Asch, the essay argues that the law alone cannot bring about the change that’s needed in the United States to realize the ADA’s promise. Attitudes to disability need to change. More people need to “get it” with regard to disability. The essay puts forward an updated account of what it means to get …

“Child Witches”: Sexual Exploitation And Abuse Of Homeless Girls In South-Southern Nigeria, Chima Agazue

Dignity: A Journal of Analysis of Exploitation and Violence

Sexual exploitation and abuse of girls is one of the endemic social problems in Nigeria. Although this problem has attracted much research attention in recent times, some newly emerged factors contributing to the problem have been mostly ignored. This study explored how the abandonment of children following their stigmatization as witches contributes to sexual exploitation and abuse of the girls in the Akwa Ibom and Cross River states of Nigeria. The study was based on the qualitative research paradigm. Data was collected via semi-structured interviews of three senior staff members of the Child’s Rights and Rehabilitation Network (CRARN)—a children’s charity …

Legal Pathways To Biden's Climate Goals, Michael B. Gerrard

Faculty Scholarship

Achieving President Biden’s goal of net-zero green­house gas emissions by 2050, with interim targets of being halfway there by 2030 and having entirely clean electric­ity by 2035, is possible with law and technologies that already exist or can be readily imagined. In the process, many more jobs would be created than lost, and aspects of the environment beyond climate change would be greatly improved. But it is a massive undertaking.

Removing Carbon Dioxide Through Seaweed Cultivation: Legal Challenges And Opportunities, Korey Silverman-Roati, Michael B. Gerrard, Romany M. Webb

Faculty Scholarship

Scientists increasingly agree that carbon dioxide removal will be needed, alongside deep emissions cuts, to stave off the worst impacts of climate change. A wide variety of technologies and strategies have been proposed to remove carbon dioxide from the atmosphere. To date, most research has focused on terrestrial-based approaches, but they often have large land requirements, and may present other risks and challenges. As such, there is growing interest in using the oceans, which have already absorbed more than a quarter of anthropogenic carbon dioxide emissions, and could become an even larger carbon sink in the future.

This paper explores …

Evolutionary Responses Of Marine Organisms To Urbanized Seascapes, S. Elizabeth Alter, Laraib Tariq, James Keanu Creed, Emmanuel Megafu

Biology, Agriculture and Chemistry Faculty Publications and Presentations

Many of the world's major cities are located in coastal zones, resulting in urban and industrial impacts on adjacent marine ecosystems. These pressures, which include pollutants, sewage, runoff and debris, temperature increases, hardened shorelines/structures, and light and acoustic pollution, have resulted in new evolutionary landscapes for coastal marine organisms. Marine environmental changes influenced by urbanization may create new selective regimes or may influence neutral evolution via impacts on gene flow or partitioning of genetic diversity across seascapes. While some urban selective pressures, such as hardened surfaces, are similar to those experienced by terrestrial species, others, such as oxidative stress, are …

Microbiome samples are inherently defined by the environment in which they are found. Therefore, data that provide context and enable interpretation of measurements produced from biological samples, often referred to as metadata, are critical. Important contributions have been made in the development of community-driven metadata standards; however, these standards have not been uniformly embraced by the microbiome research community. To understand how these standards are being adopted, or the barriers to adoption, across research domains, institutions, and funding agencies, the National Microbiome Data Collaborative (NMDC) hosted a workshop in October 2019. This report provides a summary of discussions that took …

Extracting Indigenous Jurisdiction On Private Land: The Duty To Consult And Indigenous Relations With Place In Canadian Law, Estair Van Wagner

Articles & Book Chapters

Indigenous relations with land are grounded in place-based legal orders which have been regulating the territories now making up Canada for millennia (Borrows 2010, 2018; McGregor 2010). Judicial consideration of Indigenous relations with place has focused on the duty to consult and accommodate with respect to ‘Crown land’ – lands for which federal and provincial governments are the deemed owners. This emphasis on Crown lands is logical – 89 per cent of land in Canada is held by either the federal or provincial Crown (Neimanis 2013). Indigenous claims often expressly exclude private land, wary of courts’ willingness to unsettle third-party …

Specifically, the task force would seek to define what the computing/computational contributions are to this new field, and provide guidance on computing-specific competencies in data science for departments offering such programs of study at the undergraduate level.

There are many stakeholders in the discussion of data science – these include colleges and universities that (hope to) offer data science …

Do You Copy? Post-Traumatic Stress Disorder, Auditory Processing, And Heart Rate Variability, Lyndsey Johnson

UNF Graduate Theses and Dissertations

Self -report measures used in PTSD research have the potential to limit the degree of symptom severity in military veterans, especially as there is often underreporting in this population (Kline, Falca-Dodson, Susner et al., 2010). Polyvagal Theory provides a framework assessing if physiological measures can tap into PTSD Symptomology (Porges, 1995). It is therefore hypothesized that lower scores on auditory processing tests will be positively correlated with higher scores on Stress and PTSD measures. Additionally, it is thought that lower scores on auditory processing tedts as well as higher scores on PTSD and Stress Measures will be positively correlated with …

Weak Olfactory Preferences Of The Gall Midge Asphondylia Borrichiae, Associated Fungal Endophytes And Implications On Gene Flow And Host Range Expansion, Frances S. Nagle

UNF Graduate Theses and Dissertations

Asphondylia borrichaie is a small fly (Diptera: Cecidomyiidae) that is currently undergoing host-associated sympatric divergence. Asphondylia borrichaie is an ambrosia galler, these insects utilize a host plant for oviposition, but its offspring also rely on a symbiotic fungus (or fungal community) to promote the formation of the gall as well as serve as a food source for the developing larvae. Previous studies indicate that A. borrichaie consists of two host- associated populations based on its original host plant Borrichia frutescens (Asterales: Asteraceae), and another one from the two Iva species (I. frutescens (Asterales: Asteraceae) and I. imbricata …

Inside The Zoo: Captive Giraffes’ Changes In Social Ties Throughout Membership Variations, Morgan Paige Howard

UNF Graduate Theses and Dissertations

Many animals live in gregarious, fission-fusion societies where group size and composition are continually changing. Despite this, many studies have suggested that captive animals are capable of maintaining long term social bonds with others. In captive giraffes, effects on their social bonds during membership transitions have not been studied thoroughly, however, prior research does show that social bonds are a defining factor in non-captive animals. Captive giraffe social network patterns were investigated at the Jacksonville Zoo and Botanical Gardens using all occurrence behavioral data. Based on previous research, I hypothesized that when one of the individuals in the group was …
