Implications Of 3-D Printing For Teaching Geoscience Concepts To Students With Visual Impairments, Karen E. Koehler, Tiffany A. Wild, Sean Tikkun

Journal of Science Education for Students with Disabilities

This article presents the results of a study on the use of 3-D printed models in a science classroom for students with visual impairments and examines whether the use of these models impacts student conceptual understanding and misconceptions related to geosciences concepts, specifically plate tectonics.

Data were collected one week prior to instruction, one week after instruction and throughout the 3-week instructional period. Results showed that students with visual impairments held many of the same misconceptions about plate tectonics as students who are typically sighted. All students in this study had fewer misconceptions after the instructional period than they held …

Systematics Of Malesian-Pacific Piper (Piperaceae), Rani Asmarayani

Dissertations

Comprised of ~2400 spp., Piper is a major clade in the magnoliid angiosperms. Three major groups are recognized in Piper, i.e., the Neotropical, Asian and South Pacific. Unlike Neotropical Piper,relationships in the Paleotropical Piper remain enigmatic. This study focused on the Paleotropical Piperwith emphasize on the Malesian-Pacific Piper, Malesia being the center of diversity of the genus in the Paleotropics. The goals are to evaluate relationships within Paleotropical Piper (chapter 1), to evaluate characters, morphological (chapter 1) and stem anatomical (chapter 2), that may distinguish clades, and to investigate the species boundaries focusing on the well-supported …

Parental Habituation To Human Disturbance Over Time Reduces Fear Of Humans In Coyote Offspring, Christopher J. Schell, Julie K. Young, Elizabeth V. Lonsdorf, Rachel M. Santymire, Jill M. Mateo

Wildland Resources Faculty Publications

A fundamental tenet of maternal effects assumes that maternal variance over time should have discordant consequences for offspring traits across litters. Yet, seldom are parents observed across multiple reproductive bouts, with few studies consider‐ ing anthropogenic disturbances as an ecological driver of maternal effects. We ob‐ served captive coyote (Canis latrans) pairs over two successive litters to determine whether among‐litter differences in behavior (i.e., risk‐taking) and hormones (i.e., cortisol and testosterone) corresponded with parental plasticity in habituation. Thus, we explicitly test the hypothesis that accumulating experiences of anthropogenic disturbance reduces parental fear across reproductive bouts, which should have disparate phenotypic …

Synchronous Online Tutoring For Deaf And Hard-Of-Hearing Students: An Analysis Of Observed Functions, Lisa B. Elliot, Rebecca Carpenter

Presentations and other scholarship

Literature on online learning suggests that many faculty members are reluctant to participate in online learning activities. Concerns raised include faculty concerns that the experiences may be impersonal and that technology will stand in the way of the learning experience. Despite this resistance, students are more likely to endorse online learning strategies, especially because they provide more flexibility in managing complex schedules. Previous research from the Deaf STEM Community Alliance project found that students were positive about their experiences—the opportunity to communicate online enabled students to seek out tutoring that they would not have been able to get otherwise due …

Rhizosphere Microbial Communities Of Spartina Alternifloa And Juncus Roemerianus From Restored And Natural Tidal Marshes On Deer Island, Mississippi, Olga Mavrodi, Carina M. Jung, Jed O. Eberly, Samuel Hendry, Sanchirmaa Namijilsuren, Patrick D. Biber, Karl J. Indest, Dmitri V. Mavrodi

Faculty Publications

The U. S. Gulf of Mexico is experiencing a dramatic increase in tidal marsh restoration actions, which involves planting coastal areas with smooth cordgrass (Spartina alterniflora) and black needlerush (Juncus roemerianus) for erosion control and to provide habitat for fish and wildlife. It can take decades for sedimentary cycles in restored marshes to approach reference conditions, and the contribution of the sediment microbial communities to these processes is poorly elucidated. In this study, we addressed this gap by comparing rhizosphere microbiomes of S. alterniflora and J. roemerianus from two restored marshes and a natural reference marsh located at Deer Island, …

Phylogeographic Analyses Of A Widely Distributed Populus Davidiana: Further Evidence For The Existence Of Glacial Refugia Of Cool‐Temperate Deciduous Trees In Northern East Asia, Zhe Hou, Zhaoshan Wang, Zhanyang Ye, Shuhui Du, Shuya Liu, Jianguo Zhang

Aspen Bibliography

Despite several phylogeographic studies had provided evidence to support the existence of glacial refugia of cool‐temperate deciduous trees in northeast China, the species used in these studies were limited by the species ranges, which could not exclude the possibility that northern populations were the colonists from southern refugial populations during the last glacial maximum (LGM). Here, we estimated the nucleotide variation in Populus davidiana, a widespread species distributed in Eurasia. Three groups in northeast, central, and southwest China were constructed according to the simulation results from SAMOVA, composition of chloroplast haplotypes and structure results. We revealed that the northeast …

An Explorational Study Of Educational Leaders' Attitudes, Opinions, Understanding, And Application Of Student Growth Percentile (Sgp) Data, J Lyn Turnell

Doctor of Education in Educational Leadership Dissertations

Student Growth Percentiles have recently become popular as a way to report student progress over time. Because of the perception that they are relatively simple to understand, they have also become a popular tool to use when evaluating teachers and school-based administrators, even though this is not the purpose of their design. Previous studies have examined the impact of student growth measures on teachers who are evaluated annually with a tool that includes a component of student growth. This study builds on the previous work of Clauser, Keller, and McDermott (2016) and Collins (2014). It examines the actions and opinions …

Evolutionary mechanisms underlying innovation of cell types have remained largely unclear. In multicellular eukaryotes, the evolutionary molecular origin of sperm differentiation is unknown in most lineages. Here, we report that in algal ancestors of land plants, changes in the DNA-binding domain of the ancestor of the MYB transcription factor DUO1 enabled the recognition of a new cis-regulatory element. This event led to the differentiation of motile sperm. After neo-functionalization, DUO1 acquired sperm lineage-specific expression in the common ancestor of land plants. Subsequently the downstream network of DUO1 was rewired leading to sperm with distinct morphologies. Conjugating green algae, a …

Increased Activity Of Mature Osteoblast From Rat Bone Marrow-Mesenchymal Stem Cells Tn Osteogenic Medium Exposed To Melatonin, Yugi Hari Chandra Purnama, Gondo Mastutik, Suhartono Taat Putra

Folia Medica Indonesiana

Exposure to melatonin in the cultures of Bone Marrow Mesenchymal Stem Cells (BM-MSCs) in osteogenic medium is able to induce mesenchymal stem cells and preosteoblasts into active osteoblasts via several transduction signals such as ERK 1/2. Previous studies used a single dose of 50 nM and a physiological dose of 20-200 pg/ml. The objective of the study was to obtain an optimal dose of melatonin that enhances osteoblast activity by increasing the expression of ERK1/2 and ALP levels in the culture of Rat Bone Marrow Mesenchymal Stem Cells (BM-MSCs) in osteogenic medium. This study was an in vitro experimental laboratory …

Exploring Structure-Property Relationships Of Gags To Tailor Ecm-Mimicking Hydrogels, Ralf Zimmermann, Carsten Werner, James Sterling

Business and Information Technology Faculty Research & Creative Works

Glycosaminoglycans (GAGs) are a class of linear polysaccharides that are ubiquitous in the extracellular matrix (ECM) and on cell surfaces. Due to their key role in development, homeostasis, pathogenesis, and regeneration, GAGs are increasingly used in the design of ECM-mimicking hydrogels to stimulate tissue formation and regenerative processes via specifically orchestrated cell-instructive signals. These applications first and foremost build on the ability of GAGs to effectively bind, protect, and release morphogens. The specificity and strength of morphogen-GAG interactions are largely governed by the number and spatial distribution of negatively charged sulfate groups carried by GAGs. Herein, we summarize a mean-field …

Cryo-Em Structures Of Eastern Equine Encephalitis Virus Reveal Mechanisms Of Virus Disassembly And Antibody Neutralization, Saif Hasan, Chengqun Sun, Arthur S. Kim, Yasunori Watanabe, Chun-Liang Chen, Thomas Klose, Geeta Buda, Max Crispin, Michael S. Diamond, William B. Klimstra, Michael G. Rossmann

Department of Biological Sciences Faculty Publications

Alphaviruses are enveloped pathogens that cause arthritis and encephalitis. Here, we report a 4.4-Å cryoelectron microscopy (cryo-EM) structure of eastern equine encephalitis virus (EEEV), an alphavirus that causes fatal encephalitis in humans. Our analysis provides insights into viral entry into host cells. The envelope protein E2 showed a binding site for the cellular attachment factor heparan sulfate. The presence of a cryptic E2 glycan suggests how EEEV escapes surveillance by lectin-expressing myeloid lineage cells, which are sentinels of the immune system. A mechanism for nucleocapsid core release and disassembly upon viral entry was inferred based on pH changes and capsid …

Occurrence Of Alkaloids In Grass Seeds Symbiotic With Vertically-Transmitted Epichloë Fungal Endophytes And Its Relationship With Antioxidants, Pedro E. Gundel, Charlotte E. Seal, Fernando Biganzoli, Marco A. Molina-Montenegro, Beatriz R. Vázquez-De-Aldana, Iñigo Zabalgogeazcoa, Lowell P. Bush, María A. Martínez-Ghersa, Claudio M. Ghersa

Plant and Soil Sciences Faculty Publications

Host organisms can acquire new functional traits through symbiosis. Seed-transmitted Epichloë fungal endophytes are known to protect host plants against herbivores and increase tolerance to abiotic stresses by alkaloids and antioxidants, respectively (currencies of mutualism). Whereas, alkaloids are fungal products with demonstrated effects at plant vegetative stage, few studies have focused on alkaloids in seeds. We assessed the occurrence of fungal alkaloids and determined their concentrations in seeds of two host grasses, Festuca rubra and Lolium multiflorum. Then, we sought for a relationship with the antioxidants tocochromanols and glutathione, which are involved in the control of oxidative stress. Different …

Gofish: A Versatile Nested Pcr Strategy For Environmental Dna Assays For Marine Vertebrates, Mark Y. Stoeckle, Mithun Das Mishu, Zachary Charlop-Powers

Publications and Research

Here we describe GoFish, a strategy for single-species environmental DNA (eDNA) presence/absence assays using nested PCR. The assays amplify a mitochondrial 12S rDNA segment with vertebrate metabarcoding primers, followed by nested PCR with M13-tailed, species-specific primers. Sanger sequencing confirms positives detected by gel electrophoresis. We first obtained 12S sequences from 77 fish specimens for 36 northwestern Atlantic taxa not well documented in GenBank. Using these and existing 12S records, we designed GoFish assays for 11 bony fish species common in the lower Hudson River estuary and tested seasonal abundance and habitat preference at two sites. Additional assays detected nine cartilaginous …
