Uncertainty In Employee Status Across Federal Law, Ryan Vacca

Faculty Publications

Numerous federal statutes rely on a distinction between employees and independent contractors. Based on a series of Supreme Court decisions from 1968 through 2003, courts and administrative agencies have used a common law multifactor test to draw this distinction. In an effort to enhance predictability and certainty within and across legislation, these cases have rejected a purposive approach in applying the test. But the Supreme Court has never said which, if any, of the factors are the most important in the analysis, nor has anyone determined whether the underlying purpose-enhancing predictability and certainty-has been attained.

Frequent Fire Reorganizes Fungal Communities And Slows Decomposition Across A Heterogeneous Pine Savanna Landscape, Tatiana A. Semenova-Nelsen, William J. Platt, Taylor R. Patterson, Jean Huffman, Benjamin A. Sikes

Faculty Publications

© 2019 The Authors. New Phytologist © 2019 New Phytologist Trust Pyrogenic savannas with a tree–grassland ‘matrix’ experience frequent fires (i.e. every 1–3 yr). Aboveground responses to frequent fires have been well studied, but responses of fungal litter decomposers, which directly affect fuels, remain poorly known. We hypothesized that each fire reorganizes belowground communities and slows litter decomposition, thereby influencing savanna fuel dynamics. In a pine savanna, we established patches near and away from pines that were either burned or unburned in that year. Within patches, we assessed fungal communities and microbial decomposition of newly deposited litter. Soil variables and …

Hinge Region In Dna Packaging Terminase Pul15 Of Herpes Simplex Virus: A Potential Allosteric Target For Antiviral Drugs, Lana F. Thaljeh, J. Ainsley Rothschild, Misagh Naderi, Lyndon M. Coghill, Jeremy M. Brown, Michal Brylinski

Faculty Publications

Approximately 80% of adults are infected with a member of the herpesviridae family. Herpesviruses establish life-long latent infections within neurons, which may reactivate into lytic infections due to stress or immune suppression. There are nine human herpesviruses (HHV) posing health concerns from benign conditions to life threatening encephalitis, including cancers associated with viral infections. The current treatment options for most HHV conditions mainly include several nucleoside and nucleotide analogs targeting viral DNA polymerase. Although these drugs help manage infections, their common mechanism of action may lead to the development of drug resistance, which is particularly devastating in immunocompromised patients. Therefore, …

Sympathetic Innervation Of The Interscapular Brown Adipose Tissue In Mouse, Marie François, Hayden Torres, Clara Huesing, Rui Zhang, Carson Saurage, Nathan Lee, Emily Qualls-Creekmore, Sangho Yu, Christopher D. Morrison, David Burk, Hans Rudolf Berthoud, Heike Münzberg

Faculty Publications

© 2019 The Authors. Annals of the New York Academy of Sciences published by Wiley Periodicals, Inc. on behalf of New York Academy of Sciences. The recent discovery of significant brown fat depots in adult humans has revived discussion of exploiting brown fat thermogenesis in the control of energy balance and body weight. The sympathetic nervous system (SNS) has a key role in the activation of brown fat and functional mapping of its components will be crucial for the development of specific neuromodulation techniques. The mouse is an important species used for molecular genetic modulations, but its small size is …

A Hybrid Kinematic-Acoustic System For Automated Activity Detection Of Construction Equipment, Yong-Cheol Lee

Faculty Publications

Automatically recognizing and tracking construction equipment activities is the first step towards performance monitoring of a job site. Recognizing equipment activities helps construction managers to detect the equipment downtime/idle time in a real-time framework, estimate the productivity rate of each equipment based on its progress, and efficiently evaluate the cycle time of each activity. Thus, it leads to project cost reduction and time schedule improvement. Previous studies on this topic have been based on single sources of data (e.g., kinematic, audio, video signals) for automated activity-detection purposes. However, relying on only one source of data is not appropriate, as the …

Intensive Livestock Production Causing Antibiotic Pollution In The Yinma River Of Northeast China, Hanyu Ju, Sijia Li, Y. Jun Xu, Guangxin Zhang, Jiquan Zhang

Faculty Publications

Antibiotics are increasingly used in livestock production in rural China, raising concerns over pollution and health risk in countryside waterways. The Yinma River Basin in China's far northeast is an agriculture-dominated area mixed with a densely populated province capitol city, providing a suitable area for investigating the influence of a typical land use mix in Northeast China on riverine antibiotic levels and transport. In this study, we sampled water along the Yinma River from upstream to downstream in a wet and a dry season and analyzed the samples for two popularly used antibiotics, ciprofloxacin (CIP) and norfloxacin (NOR). The goal …

On-Site Capabilities Of A Mobile Laboratory For Aquatic Germplasm Cryopreservation, William M. Childress, Brian Bosworth, Edward Chesney, Ronald B. Walter, Terrence R. Tiersch

Faculty Publications

The cryopreservation of genetic material can be an important tool for researchers and others involved with imperiled fishes, wild fisheries, aquaculture, and biomedical research. The standardization and reliable collection of diverse, high-quality samples are persistent challenges to the successful cryopreservation of aquatic species. The overall goal of this study was to work with different user groups, cryopreserving sperm on-site at their facilities to evaluate the uses and challenges of a mobile laboratory with high-throughput and quality control capabilities comparable to those of a specialized central facility. The objectives were to demonstrate the collection and cryopreservation of sperm from (1) large-bodied …

Postbreeding Habitat Use By Golden-Cheeked Warblers (Setophaga Chrysoparia), Melanie R. Colón, Mark R. Hutchinson, Ashley M. Long, Gary Voelker, Michael L. Morrison

Faculty Publications

The period following breeding but prior to migration is an important, though understudied, component of the avian annual life cycle. We quantified habitat use by endangered Golden-cheeked Warblers (Setophaga chrysoparia) during the postbreeding period in Golden-cheeked Warbler breeding habitat (i.e., oak-juniper [Quercus-Juniperus] woodlands) predominated by Texas oak (Quercus buckleyi) or post oak (Q. stellata), as well as in immediately adjacent oak woodland, oak savanna, and riparian vegetation not usually associated with breeding activity for this species. Most (87%) of the Golden-cheeked Warblers we detected were in oak-juniper woodlands, especially in Texas oak sites, but we also detected warblers in each …

Language Nests On The Move: The Case Of Võro Pre-Primary Education In Estonia, Kara D. Brown, Mariko Faster

Faculty Publications

This article considers the circuitous route of knowledge exchange from South (New Zealand)-to North (Finland)-to regional South (Estonia) by examining the development of Võro language nests (keelepesä) in Estonia. Language nests reflect the global nature of educational knowledge exchange as well as the importance of networks of languageresearchers and activists in this policy inspiration. Estonia is a fascinating case for understanding the international spread and local development of the language-nest approach in a post-Socialist context. The authors draw on concepts of policy borrowing and diffusion and the “grammar of schooling” to explore the spread of the language nest approach and …

Visualizing Nutrient Effects On Root Pattern Formation, Robert E. Zdor

Faculty Publications

This lab gives students hands-on experience with visualizing the root architecture of plants exposed to varying concentrations of the vital nutrient phosphorus. By maintaining Brassica sp. seedlings in the presence of different quantities of phosphate, students can quantify changes in the number of lateral roots as an example of how the environment influences plant pattern formation. Additional variables in the experimental design, such as the use of plant mutants altered in plant regulator action or the presence of plant regulators in the plant growth medium, allow for exploration of how plant growth regulators are involved in root development. The quantitative …

Boateng, Zeina Jamaluddine, Joshua D. Miller, Edward A. Frongillo, Torsten B. Neilands, Shaleans M. Collins, Amber Wutich, Wendy E. Jepson, Justin Stoler

Faculty Publications

Objective Progress towards equitable and sufficient water has primarily been measured by population-level data on water availability. However, higher-resolution measures of water accessibility, adequacy, reliability and safety (ie, water insecurity) are needed to understand how problems with water impact health and well-being. Therefore, we developed the Household Water InSecurity Experiences (HWISE) Scale to measure household water insecurity in an equivalent way across disparate cultural and ecological settings.

Methods Cross-sectional surveys were implemented in 8127 households across 28 sites in 23 low-income and middle-income countries. Data collected included 34 items on water insecurity in the prior month; socio-demographics; water acquisition, use …

Life Lessons With Atreus And Chloe: Mature Video Games As Opportunity Spaces For Family Conversations, Angela Vanden Elzen, Adam L. Vanden Elzen

Faculty Publications

The effects of childhood and adolescent exposure to mature video games has been a recurring topic in popular culture as well as academic research for many years. While many studies have been conducted, a consensus has not been reached. Video games have been shown,however,to play a positive role in family togetherness and act as an opportunity space to encourage family discussion. Through a review of the literature, this article argues that mature video games can serve as opportunity spaces for families with older children and teens. A case study in which the M-rated video games,Life is Strange: Before the Storm …

Segmentation Of Severe Occupational Incidents In Agribusiness Industries Using Latent Class Clustering, Fatemeh Davoudi Kakhki, Steven Freeman, Gretchen Mosher

Faculty Publications

One of the principle objectives in occupational safety analysis is to identify the key factors that affect the severity of an incident. To identify risk groups of occupational incidents and the factors associated with them, statistical analysis of workers’ compensation claims data is performed using latent class clustering, for the segmentation of 1031 severe occupational incidents in agribusiness industries in the Midwest region of the United States between 2008–2016. In this study, severe incidents are those with workers’ compensation costs equal to or greater than $100,000 (USD). Based on the latent class clustering results, three risk groups are identified with …

Multilevel Analysis In Rural Cancer Control: A Conceptual Framework And Methodological Implications, Tine Verreet, Cory J. Weaver, Hiromu Hino, Masahiko Hibi, Fabienne E. Poulain

Faculty Publications

Mitochondria are abundantly detected at the growth cone, the dynamic distal tip of developing axons that directs growth and guidance. It is, however, poorly understood how mitochondrial dynamics relate to growth cone behavior in vivo, and which mechanisms are responsible for anchoring mitochondria at the growth cone during axon pathfinding. Here, we show that in retinal axons elongating along the optic tract in zebrafish, mitochondria accumulate in the central area of the growth cone and are occasionally observed in filopodia extending from the growth cone periphery. Mitochondrial behavior at the growth cone in vivo is dynamic, with mitochondrial positioning …

Structural Properties And Cellular Expression Of Afrlea6, A Group 6 Late Embryogenesis Abundant Protein From Embryos Of Artemia Franciscana, Blase M. Leblanc, Mike T. Le, Brett Janis, Michael A. Menze, Steven C. Hand

Faculty Publications

© 2019, Cell Stress Society International. Late embryogenesis abundant (LEA) proteins are intrinsically disordered proteins (IDPs) commonly found in anhydrobiotic organisms and are frequently correlated with desiccation tolerance. Herein we report new findings on AfrLEA6, a novel group 6 LEA protein from embryos of Artemia franciscana. Assessment of secondary structure in aqueous and dried states with circular dichroism (CD) reveals 89% random coil in the aqueous state, thus supporting classification of AfrLEA6 as an IDP. Removal of water from the protein by drying or exposure to trifluoroethanol (a chemical de-solvating agent) promotes a large gain in secondary structure of AfrLEA6, …

Copyright © 2019 American Society of Plant Biologists. All rights reserved. The plant-specific translation initiation complex eIFiso4F is encoded by three genes in Arabidopsis (Arabidopsis thaliana)-genes encoding the cap binding protein eIFiso4E (eifiso4e) and two isoforms of the large subunit scaffolding protein eIFiso4G (i4g1 and i4g2). To quantitate phenotypic changes, a phenomics platform was used to grow wild-type and mutant plants (i4g1, i4g2, i4e, i4g1 × i4g2, and i4g1 × i4g2 × i4e [i4f]) under various light conditions. Mutants lacking both eIFiso4G isoforms showed the most obvious phenotypic differences from the wild type. Two-dimensional differential gel electrophoresis and mass spectrometry …

Development Of Germplasm Repositories To Assist Conservation Of Endangered Fishes: Examples From Small-Bodied Livebearing Fishes, Yue Liu, Harvey Blackburn, Sabrina S. Taylor, Terrence R. Tiersch

Faculty Publications

Germplasm repositories are a necessary tool for comprehensive conservation programs to fully preserve valuable genetic resources of imperiled animals. Cryopreserved germplasm can be used in the future to produce live young for integration into other conservation projects, such as habitat restoration, captive breeding, and translocations; thus compensating for genetic losses or negative changes that would otherwise be permanent. Although hundreds of cryopreservation protocols for various aquatic species have been published, there are great difficulties in moving such research forward into applied conservation projects. Successful freezing of sperm in laboratories for research does not guarantee successful management and incorporation of genetic …

There is evidence from human twin and family studies as well as mouse and rat selection experiments that there are considerable interindividual differences in the response of cardiorespiratory fitness (CRF) and other cardiometabolic traits to a given exercise programme dose. We developed this consensus statement on exercise response variability following a symposium dedicated to this topic. There is strong evidence from both animal and human studies that exercise training doses lead to variable responses. A genetic component contributes to exercise training response variability. In this consensus statement, we (1) briefly review the literature on exercise response variability and the various …

Additive And Heterozygous (Dis)Advantage Gwas Models Reveal Candidate Genes Involved In The Genotypic Variation Of Maize Hybrids To Azospirillum Brasilense, Miriam Suzane Vidotti, Danilo Hottis Lyra, Júlia Silva Morosini, Ítalo Stefanine Correia Granato, Maria Carolina Quecine, João Lúcio De Azevedo, Roberto Fritsche-Neto

Faculty Publications

Maize genotypes can show different responsiveness to inoculation with Azospirillum brasilense and an intriguing issue is which genes of the plant are involved in the recognition and growth promotion by these Plant Growth-Promoting Bacteria (PGPB). We conducted Genome-Wide Association Studies (GWAS) using additive and heterozygous (dis)advantage models to find candidate genes for root and shoot traits under nitrogen (N) stress and N stress plus A. brasilense. A total of 52,215 Single Nucleotide Polymorphism (SNP) markers were used for GWAS analyses. For the six root traits with significant inoculation effect, the GWAS analyses revealed 25 significant SNPs for the N stress …

Strangers In The Village: James Baldwin, Teju Cole, And Glenn Ligon, Monika Gehlawat

Faculty Publications

This essay uses Edward Said’s theory of affiliation to consider the relationship between James Baldwin and contemporary artists Teju Cole and Glenn Ligon, both of whom explicitly engage with their predecessor’s writing in their own work. Specifically, Baldwin’s essay “Stranger in the Village” (1953) serves a through-line for this discussion, as it is invoked in Cole’s essay “Black Body” and Ligon’s visual series, also titled Stranger in the Village. In juxtaposing these three artists, I argue that they express the dialectical energy of affiliation by articulating ongoing concerns of race relations in America while distinguishing themselves from Baldwin in terms …

When Good Girls Go Bad (Or Do They?): Nymphomania And Lycanthropy In Verga’S “La Lupa”, Ilona Klein

Faculty Publications

At some point during early development, most children are afraid of the imaginary wolf under the bed or the wolf that hides in the closet at night. Traditional bedtime stories such as Little Red Riding Hood certainly do not help assuage such fears: these are atavistic dreads, similar to being scared of the dark or of death.1 In childhood culture, the wolf represents the “other,” the “furry non-human,” and almost always the viciously violent. Later, as adults, the occasional dream of wolverine violence, or of human transformation into a wolf (a lycanthropic aversion) might very well create anxiety and apprehension.2 …

Functional And Anatomical Variations In Retinorecipient Brain Areas In Arvicanthis Niloticus And Rattus Norvegicus: Implications For The Circadian And Masking Systems, Dorela D. Shuboni-Mulligan, Breyanna L. Cavanaugh, Anne Tonson, Erik M. Shapiro, Andrew J. Gall

Faculty Publications

Daily rhythms in light exposure influence the expression of behavior by entraining circadian rhythms and through its acute effects on behavior (i.e., masking). Importantly, these effects of light are dependent on the temporal niche of the organism; for diurnal organisms, light increases activity, whereas for nocturnal organisms, the opposite is true. Here we examined the functional and morphological differences between diurnal and nocturnal rodents in retinorecipient brain regions using Nile grass rats (Arvicanthis niloticus) and Sprague-Dawley (SD) rats (Rattus norvegicus), respectively. We established the presence of circadian rhythmicity in cFOS activation in retinorecipient brain regions in …

Evaluation Of The Stock Structure Of Cobia (Rachycentron Canadum) In The Southeastern United States By Using Dart-Tag And Genetics Data, Matt Perkinson, Tanya Darden, Maggie Jamison, Matt J. Walker, Michael R. Denson, James Franks, Read Hendon, Susanna Musick, Eric S. Orbensen

Faculty Publications

Available tag-recapture and population genetics data for cobia (Rachycentron canadum) in the southeastern United States were evaluated to provide information on population structure and determine the geographic boundary between stocks in the Gulf of Mexico and the Atlantic Ocean. The movements of 1750 cobia were evaluated on the basis of assigned tagging and recapture zones. Genetic samples from an additional 2796 cobia collected during the presumed spawning season were genotyped at 10 microsatellite loci, and standard population genetic statistical analyses were applied to the resulting sample data set. Tag-recapture results indicate that cobia tagged south of Cape Canaveral, …

Prospects For The Sustainable Management Of Public Oyster Resources, Thomas M. Soniat, Nathan A. Cooper, Eric N. Powell

Faculty Publications

Common-pool resources such as public oyster grounds are especially vulnerable to overexploitation and habitat loss. Like those elsewhere, oyster populations and habitat of Louisiana public grounds are in decline. To maintain reef habitat and increase oyster abundance, a sustainable harvest model is applied, which allows harvest above that required to maintain reef cultch stasis. The model is restrained to promote shell gain by limiting fishing by area, type (sack versus seed), effort, and season. Harvest quotas and cultch removal rates derived from shell-budget–based modeling are a foundation for sustainable management of public oyster resources.
