Adjective Learning In Young Typically Developing Children And Children With Developmental Language Disorder: A Retrieval-Based Approach, Laurence B. Leonard, Patricia Deevy, Jeffrey D. Karpicke, Sharon Christ, Christine Weber, Justin B. Kueser, Eileen Haebig

Faculty Publications

Purpose: There are strong retention benefits when learners frequently test themselves during the learning period. This practice of repeated retrieval has recently been applied successfully to children’s word learning. In this study, we apply a repeated retrieval procedure to the learning of novel adjectives by preschool-age children with developmental language disorder (DLD) and their typically developing (TD) peers. We ask whether the benefits of retrieval extend to children’s ability to apply the novel adjectives to newly introduced objects sharing the same characteristics as the objects used during the learning period. Method: Fourteen children with DLD (Mage = 62.64 months) and …

From The Arctic To The Tropics: Multibiome Prediction Of Leaf Mass Per Area Using Leaf Reflectance, Shawn P. Serbin, Jin Wu, Kim S. Ely, Eric L. Kruger, Philip A. Townsend, Ran Meng, Brett T. Wolfe, Adam Chlus, Zhihui Wang, Alistair Rogers

Faculty Publications

Leaf mass per area (LMA) is a key plant trait, reflecting tradeoffs between leaf photosynthetic function, longevity, and structural investment. Capturing spatial and temporal variability in LMA has been a long-standing goal of ecological research and is an essential component for advancing Earth system models. Despite the substantial variation in LMA within and across Earth's biomes, an efficient, globally generalizable approach to predict LMA is still lacking. We explored the capacity to predict LMA from leaf spectra across much of the global LMA trait space, with values ranging from 17 to 393 g m−2. Our dataset contained leaves from a …

Spatiotemporal Variability Of Fire Characteristics Affect Animal Responses In Pyric Landscapes, Bradley S. Cohen, Thomas J. Prebyl, Bret A. Collier, Michael J. Chamberlain

Faculty Publications

Background: Behavioral responses are the most immediate ways animals interact with their environment, and are primary mechanisms by which individuals mitigate mortality risk while ensuring reproductive success. In disturbance-driven landscapes, animals must adjust behaviors both spatially and temporally to maximize individual fitness. Prescribed fire is an important ecosystem driver in many coniferous forests, as fire cycles nutrients, creates spatially heterogeneous distributions in quantity and quality of forage and cover, and provides opportunities for fire-adapted taxa. Because fire immediately shifts resource distribution, and fire characteristics may drive behavioral responses to recent burns, we examined behavioral responses of 105 Global Positioning System …

Winter Cover Crops Effect On Soil Moisture And Soybean Growth And Yield Under Different Tillage Systems, Bharat Sharma Acharya, Syam Dodla, Lewis A. Gaston, Murali Darapuneni, Jim J. Wang, Seema Sepat, Hari Bohara

Faculty Publications

Current agricultural systems heavily rely on intensive tillage and inorganic fertilizer inputs. This tradition increases the cost of agricultural production and negatively affects agricultural systems and environment. Conservation practices, such as cover crops (CCs) and no-till (NT), could serve as a management approach to promote soil health and agricultural sustainability. There is limited understanding of CCs effect on soil properties, crop growth and yield under different tillage systems in the humid sub-tropical region of the US. This study evaluated the effect of winter cover crops [wheat (Triticum aestivum) and hairy vetch (Vicia villosa)] and different tillage systems [NT and conventional …

Genetic Diversity, Population Structure, And Marker-Trait Association For Drought Tolerance In Us Rice Germplasm, Uttam Bhattarai, Prasanta K. Subudhi

Faculty Publications

Drought is a major constraint in some rice-growing areas of the United States. Its impact is most severe at the reproductive stage resulting in low grain yield. Therefore, assessment of genetic and phenotypic variation for drought tolerance in US rice germplasm is necessary to accelerate the breeding effort. Evaluation of 205 US rice genotypes for drought tolerance at the reproductive stage revealed tolerant response in rice genotypes Bengal, Jupiter, Cypress, Jazzman, Caffey, and Trenasse. Harvest index and fresh shoot weight were identified as important traits to explain the majority of variability among the genotypes under drought tolerance. Genotyping with 80 …

The Influence Of Progesterone On Bovine Uterine Fluid Energy, Nucleotide, Vitamin, Cofactor, Peptide, And Xenobiotic Composition During The Conceptus Elongation-Initiation Window, Constantine A. Simintiras, José M. Sánchez, Michael Mcdonald, Patrick Lonergan

Faculty Publications

Conceptus elongation coincides with one of the periods of greatest pregnancy loss in cattle and is characterized by rapid trophectoderm expansion, commencing ~ Day 13 of pregnancy, i.e. before maternal pregnancy recognition. The process has yet to be recapitulated in vitro and does not occur in the absence of uterine gland secretions in vivo. Moreover, conceptus elongation rates are positively correlated to systemic progesterone in maternal circulation. It is, therefore, a maternally-driven and progesterone-correlated developmental phenomenon. This study aimed to comprehensively characterize the biochemical composition of the uterine luminal fluid on Days 12–14 – the elongation-initiation window – in heifers …

The Marine Geological Imprint Of Antarctic Ice Shelves, James A. Smith, Alastair G.C. Graham, Alix L. Post, Claus Dieter Hillenbrand, Philip J. Bart, Ross D. Powell

Faculty Publications

Reductions in the thickness and extent of Antarctic ice shelves are triggering increased discharge of marine-terminating glaciers. While the impacts of recent changes are well documented, their role in modulating past ice-sheet dynamics remains poorly constrained. This reflects two persistent issues; first, the effective discrimination of sediments and landforms solely attributable to sub-ice-shelf deposition, and second, challenges in dating these records. Recent progress in deciphering the geological imprint of Antarctic ice shelves is summarised, including advances in dating methods and proxies to reconstruct drivers of change. Finally, we identify several challenges to overcome to fully exploit the paleo record.

A green and simple process for preparing the polyethylene glycol passivated fluorescent carbon dots (CDs-PEG) have been studied by a microwave pyrolysis method, using gelatin and PEG as starting materials. This method is very effective for development of carbon-based quantum dots from gelatin with high quantum yield (QY). The synthesized CDs-PEG were found to emit blue photoluminescence (PL) with a maximum QY of 34%. At the following research, we investigated the effect of the presence of PEG on PL intensity, and the result showed that CDs-PEG becomes stronger PL properties than pure CDs from gelatin. The synthesized CDs-PEG were characterized …

Survival And Inactivation Of Salmonella Enterica Serovar Typhimurium On Food Contact Surfaces During Log, Stationary And Long-Term Stationary Phases, Dorra Djebbi-Simmons, Wenqing Xu, Marlene Janes, Joan King

Faculty Publications

One of the most important transmission routes of foodborne pathogens is through contaminated food contact surfaces. In this study, we investigated the survival and inactivation of Salmonella enterica serovar Typhimurium on frequently used food contact surfaces in household settings, including plastic cutting board (CB), formica laminate (LA), and stainless steel (SS) surfaces. S. Typhimurium at log (6 h), stationary (24 h), or long-term stationary (LTS) (14 days) phases were evaluated. Results showed that, at medium and high microbial loads, LTS phase cells had significantly higher survivor population compared to log and stationary phase cells at 24 h after inoculation (p < 0.05). Disinfection study showed that LTS phase cells were very resilient to sodium hypochlorite when the initial microbial load was high with disinfection efficacy ranging from 26 to 35%. Scanning electron microscopy of these surfaces at 24 h after inoculation with a high microbial load revealed an early biofilm structure.

Virtual Briefing At The Supreme Court, Jeffrey L. Fisher, Allison Orr Larsen

Faculty Publications

The open secret of Supreme Court advocacy in a digital era is that there is a new way to argue to the Justices. Today's Supreme Court arguments are developed online: they are dissected and explored in blog posts, fleshed out in popular podcasts, and analyzed and re-analyzed by experts who do not represent the parties or have even filed a brief in the case at all. This "virtual briefing" (as we call it) is intended to influence the Justices and their law clerks but exists completely outside of traditional briefing rules. This article describes virtual briefing and makes a case …

Psychogenic Antecedents And Apparel Customization: Moderating Effects Of Gender, Su Kyung Seo, Chunmin Lang

Faculty Publications

The impact of gender is critical in consumer behavior; however, gender differences have been overlooked in consumer studies. The purpose of this study is to examine how behavior-inducing psychogenic needs (i.e., need for uniqueness, self-promotion, and social identity) influence the way individuals perceive apparel customization, leading to buying intention of customized apparel products. Further, to identify whether gender plays a moderating role in the relationships between those psychogenic needs and the perception of apparel customization. The conceptual model was tested by conducting an online survey of 338 samples from college students in the United States. Structural equation modeling (SEM) was …

Inoculation of detached strawberry leaves with Colletotrichum species may provide an accurate, rapid, nondestructive method of identifying anthracnose-resistant germplasm. The purpose of this study was to statistically compare two methods (visual and image analysis) of evaluating disease severity of strawberry germplasm screened for anthracnose resistance. Detached leaves of 77 susceptible and resistant strawberry clones were inoculated with one Colletotrichum gloeosporioides (Penz.) Penz. & Sacc. and two C. fragariae A. N. Brooks isolates. Anthracnose disease symptoms on each leaf were assessed quantitatively via computer-based image analysis to determine percentage lesion area and qualitatively by two independent raters using a visual disease …

Distinguishing Anuran Species By High-Resolution Melting Analysis Fo The Coi Barcode (Coi-Hrm), Steven Everman, Shiao Y. Wang

Faculty Publications

Taxonomic identification can be difficult when two or more species appear morphologically similar. DNA barcoding based on the sequence of the mitochondrial cytochrome c oxidase 1 gene (COI) is now widely used in identifying animal species. High‐resolution melting analysis (HRM) provides an alternative method for detecting sequence variations among amplicons without having to perform DNA sequencing. The purpose of this study was to determine whether HRM of the COI barcode can be used to distinguish animal species. Using anurans as a model, we found distinct COI melting profiles among three congeners of both Lithobates spp. and Hyla spp. Sequence variations …

The Great Unfulfilled Promise Of Tinker, Mary-Rose Papandrea

Faculty Publications

The most famous line from Tinker v. Des Moines Independent School District is that “[i]t can hardly be argued that either students or teachers shed their constitutional rights to freedom of speech or expression at the schoolhouse gate.” 393 U.S. 503, 506. People who know only this line from Tinker—and the victory it gave to the Vietnam-war protesting students—likely think of it as an incredibly speech-protective decision. It turns out that although Tinker contains lofty language about the importance of student speech rights, it sowed the seeds for the erosion of those very same rights. In the past …

Deep Donors And Acceptors In Β-Ga2O3 Crystals: Determination Of The Fe2+/3+ Level By A Noncontact Method, Christopher A. Lenyk, Timothy D. Gustafson, Larry E. Halliburton, Nancy C. Giles

Faculty Publications

Electron paramagnetic resonance (EPR), infrared absorption, and thermoluminescence (TL) are used to determine the Fe^2+/3+ level in Fe-doped β-Ga₂O₃ crystals. With these noncontact spectroscopy methods, a value of 0.84 ± 0.05 eV below the conduction band is obtained for this level. Our results clearly establish that the E2 level observed in deep level transient spectroscopy (DLTS) experiments is due to the thermal release of electrons from Fe²⁺ ions. The crystals used in this investigation were grown by the Czochralski method and contained large concentrations of Fe acceptors and Ir donors, and trace amounts of Cr …

The Case For Hyrcanus Ii As The “Wicked Priest” And A Pirate: Evidence From Neglected Roman Historical Sources, Kenneth Atkinson

Faculty Publications

Scholars have long debated the identity of the mysterious person denounced in the Dead Sea Scrolls by the sobriquet the Wicked Priest (הכוהן הרשע). Since the discovery of the Scrolls, researchers have identified nearly twenty persons as the Wicked Priest. Some view this vast number of proposals as indicative of a faulty method for understanding the history of the community behind these texts. This is because such efforts assume the Wicked Priest was an actual person. Consequently, scholars seeking to uncover his identity use material from Josephus, Philo, Pliny, and other writers to interpret the references to him in the …

The “Three Nets Of Belial” In The Dead Sea Scrolls: A Pre-Qumran Tradition, Kenneth Atkinson

Faculty Publications

Explicit quotations and allusions to writings from the apocrypha and pseudepigrapha are rare in the Dead Sea Scrolls. For this reason, the two references to non-canonical writings in the Damascus Document (CD) are of particular importance. The first is a citation from the well-known Book of Jubilees in CD 16:3-4. Literature on Jubilees and CD is quite abundant. However, the second and more enigmatic passage in CD is the topic of this paper. It has much to tell us about the source of the theology and beliefs reflected in the Dead Sea Scrolls. In this citation, found in CD 4:15, …

What’S The Point? The Missing Piece Of Criminal Justice Reform Through Consensus And Compromise, Jelani Jefferson Exum

Faculty Publications

(Excerpt)

Criminal justice reform has had a firm place in news headlines for more than a decade. When the mass incarceration crisis came to the fore in 2008, with reports that one in a hundred adults in America was behind bars, there had already long been cries for reducing the prison and jail populations. Reform has mainly been sought through two approaches: consensus through ballot initiative or legislative compromise. But these modes of reform share a fundamental failure: both often lack a clear articulation of the purpose of criminal sentencing. In other words, “What’s the point?” Without an agreement on …
