Meaningful Hope For Teachers In Times Of High Anxiety And Low Morale, Carrie Nolan, Sarah Marie Stitzlein

Democracy & Education

Many teachers struggle to maintain or build hope among themselves and their students in today’s climate of high anxiety and low morale. This article describes and responds to those challenging conditions. It offers teachers and scholars of education a philosophically sophisticated and feasible understanding of hope. This notion of hope is grounded in pragmatism and grows out of the pragmatist commitment to meliorism. Hope is described as a way of living tied to specific contexts that brings together reflection and intelligent action alongside imagination and gratitude. Such hope is realistic and generative, rendering it well suited for teachers struggling in …

The Development Of A Systematic Coding System For Elementary Students’ Drawings Of Engineers, Nicole Weber, Daphne Duncan, Melissa Dyehouse, Johannes Strobel, Heidi A. Diefes-Dux

Journal of Pre-College Engineering Education Research (J-PEER)

The Draw an Engineer Test (DAET) is a common measure of students’ perceptions of engineers. The coding systems currently used for K-12 research are general rubrics or checklists to capture the images presented in the drawing, which leave out some of the richness of students’ perceptions, currently only captured with an accompanying student interview. The purpose of this study is to build a reliable coding system, which first establishes an inventory of pictorial elements irrespective of their potential relationship with engineering and second captures aspects of students’ engineering perceptions inductively (from the ground up) while at the same time incorporating …

Problems Associated With A Lack Of Cohesive Policy In K-12 Pre-College Engineering, John Chandler, A. Dean Fontenot, Derrick Tate

Journal of Pre-College Engineering Education Research (J-PEER)

This article identifies a number of issues associated with current STEM education reform efforts, especially with regard to efforts to integrate engineering education into the K-12 curriculum. Precollege engineering is especially problematic in STEM reform since there is no well-established tradition of engineering in the K-12 curriculum. This discussion aims at identifying some of the issues and problems that serve to impede implementation of engineering education in the K-12 environment. Historically, engineering education has been the purview of higher education, and the epistemology of engineering education has not evolved to specifically inform the exigencies of K-12 education.

Middle-And High-School Students’ Interest In Nanoscale Science And Engineering Topics And Phenomena, Kelly Hutchinson, George M. Bodner, Lynn Bryan

Journal of Pre-College Engineering Education Research (J-PEER)

Research has shown that an increase in students’ interest in science and engineering can have a positive effect on their achievement (Baird, 1986; Eccles & Wigfield, 2002; French, Immekus & Oakes, 2005; Schiefele, Krapp, & Winteler, 1992; Schwartz Bloom & Haplin, 2003; Weinburgh, 1995). Whereas many NSF-funded programs in materials science and nanotechnology have included efforts to develop curriculum materials for use in secondary or tertiary classrooms, relatively little work has been done to determine the topics that increase students’ interest in science, engineering, and technology. As part of the work done by the National Center for Learning and Teaching …

Knowledge Integration And Wise Engineering, Jennifer L. Chiu, M. C. Linn

Journal of Pre-College Engineering Education Research (J-PEER)

Recent efforts in engineering education focus on introducing engineering into secondary math and science courses to improve science, technology, engineering, and math (STEM) education (NAS, 2010). Infusing engineering into secondary classrooms can increase awareness of and interest in STEM careers, help students see the relevance of science and math in their everyday lives, and increase STEM literacy. This paper describes how the knowledge integration framework provides research-based guidelines to help secondary students develop and connect science and engineering concepts. Results from technology enhanced curriculum units demonstrate how instruction based on knowledge integration principles and patterns using the Web based Inquiry …

Engineering An Optimal Bioartificial Pancreas For Islet Transplantation Using Bioactive Scaffolds, Eileen Pedraza

Open Access Dissertations

Clinical islet transplantation is a promising treatment for type 1 diabetes. It involves the transplantation of pancreatic islets, isolated from a donor, into the portal vein of a recipient in order to replace his/her dysfunctional islets. Though promising, islet implantation into the liver is greatly hindered by numerous problems, including mechanical stresses, inflammatory responses, exposure to high drug and toxin loads, as well as irretrievability. In order to address these concerns, investigation into alternative implant sites, such as the subcutaneous site, has intensified. Transplantation of islets within these extrahepatic sites is commonly met with three primary obstacles: 1) inadequate spatial …

The Transition From 3-D To 2-D Visual Stimuli And Its Effect On Paired-Associate Learning, Amanda Beers

Mahurin Honors College Capstone Experience/Thesis Projects

A single experiment investigated the influence of varying dimensions of visual stimuli on the ability of academically gifted adolescents to recall paired-associations. Fifty-two participants were randomly assigned to one of four groups. Each group was asked to memorize the same set of 15 paired-word associations. The first group was presented with words only. The second group was presented with words and 2- dimensional (2-D) representations of each word. The third group was presented with words along with 3-dimensional (3-D) representations of the words. The fourth group was also presented words along with 3-D objects; however, this group was instructed to …

A Compact Guide To The Diagnosis And Management Of Neurofibromatosis Type 1, Timothy Beer, David Strayer, Md, Phd

Department of Pathology, Anatomy, and Cell Biology Resident's Posters

Brief Introduction

Neurofibromatosis type 1 (NF-1) is a multisystem neurocutaneous disorder resulting from mutations in the NF-1 gene on chromosome 17 (q11.2). Mutations in NF-1 result in deficient activity of the tumor suppresor protein neurofibromin, allowing for uncontrolled constitutive activity of the proliferative Raspathway in several neural cell types, including neurons, oligodendrocytes, astrocytes and Schawnn cells. Half of NF-1 cases are inherited in autosomal dominant fashion, while half develop sporadically. The syndrome has 100% penetrance but highly variable expressivity. The prevalence of this syndrome is 1/3,000, making it common enough to warrant YOU, the physician, taking a moment to learn …

Transplantation Of Adult Mouse Ips Cell-Derived Photoreceptor Precursors Restores Retinal Structure And Function In Degenerative Mice, Budd A. Tucker, In-Hyun Park, Sara D. Qi, Henry J. Klassen, Caihui Jiang, Jing Yao, Stephen Redenti, George Q. Daley, Michael J. Young

Publications and Research

This study was designed to determine whether adult mouse induced pluripotent stem cells (iPSCs), could be used to produce retinal precursors and subsequently photoreceptor cells for retinal transplantation to restore retinal function in degenerative hosts. iPSCs were generated using adult dsRed mouse dermal fibroblasts via retroviral induction of the transcription factors Oct4, Sox2, KLF4 and c-Myc. As with normal mouse ES cells, adult dsRed iPSCs expressed the pluripotency genes SSEA1, Oct4, Sox2, KLF4, c-Myc and Nanog. Following transplantation into the eye of immunecompromised retinal degenerative mice these cells proceeded to form teratomas containing tissue comprising all three germ layers. At …

Nudibranch Predators Of Octocorallia, Eric Brown

HCNSO Student Capstones

Nudibranchs are soft-bodied marine heterobranch gastropod molluscs which lack a shell and mantle cavity. The basic body plan is bilaterally symmetrical with an expanded notum, but in regards to other physical characteristics they exhibit a wide range of forms. Compared to other molluscs, evolutionarily the head and body became flattened and streamlined and tentacles have been lost or shifted to different areas of the body. Nudibranchs are found in many variations of size and color; despite the fact that these animals in general are noted for flamboyant colors and prominent external anatomical structures, many species rely upon a more cryptic …

The Influence Of Family Structure And Transitions On Parenting, Income, Residential Mobility, And Substance Initiation In Early Adolescence: A Comparison Of Caucasian And African American Youth, Sally Mays

Theses and Dissertations

The effect of family structure on youth adjustment has received increasing attention as historical trends in single parenting, divorce, remarriage, and cohabitation with partners and extended family members have produced a diverse constellation of structures. African American youth are less likely than Caucasian youth to live in an “intact” family. Links between family structure and a variety of indices of youth adjustment have been established, although a relatively understudied outcome is that of substance initiation, despite its association with dependence and other negative sequelae. The dynamic effect of transitions has additionally been less studied than the static effect of structure. …

The Good, The Bad, And The Rare: Memory For Partners In Social Interactions, Jenny Volstorf, Jörg Rieskamp, Jeffrey R. Stevens

Department of Psychology: Faculty Publications

For cooperation to evolve via direct reciprocity, individuals must track their partners’ behavior to avoid exploitation. With increasing size of the interaction group, however, memory becomes error prone. To decrease memory effort, people could categorize partners into types, distinguishing cooperators and cheaters. We explored two ways in which people might preferentially track one partner type: remember cheaters or remember the rare type in the population. We assigned participants to one of three interaction groups which differed in the proportion of computer partners’ types (defectors rare, equal proportion, or cooperators rare). We extended research on both hypotheses in two ways. First, …

Passive Immunization Reduces Behavioral And Neuropathological Deficits In An Alpha-Synuclein Transgenic Model Of Lewy Body Disease, Troy Rohn

Biology Faculty Publications and Presentations

Dementia with Lewy bodies (DLB) and Parkinson's Disease (PD) are common causes of motor and cognitive deficits and are associated with the abnormal accumulation of alpha-synuclein (α-syn). This study investigated whether passive immunization with a novel monoclonal α-syn antibody (9E4) against the C-terminus (CT) of α-syn was able to cross into the CNS and ameliorate the deficits associated with α-syn accumulation. In this study we demonstrate that 9E4 was effective at reducing behavioral deficits in the water maze, moreover, immunization with 9E4 reduced the accumulation of calpain-cleaved α-syn in axons and synapses and the associated neurodegenerative deficits. In vivo studies …

Modeling Saltmarsh Sparrow Distribution In Connecticut, Susan T. Meiman

Master's Theses

To develop a map that would predict where saltmarsh sparrows live and reproduce in Connecticut, I compared models to test a) whether field data or remote-sensing data most effectively characterized within-marsh conditions that relate to sparrow occurrence, and b) whether including landscape-level variables improved model fit.  The best sparrow presence model used a variable derived from raw spectral reflectance values associated with plots where sparrows did not occur, while the best nest presence model used a combination of vegetation structure descriptions.   A second nest model, built using high resolution remote sensing data that organized marsh characteristics into high and low …

Discriminative Stimulus Properties Of 3-Substituent Rimonabant Analogs, D. Matthew Walentiny

Theses and Dissertations

Cannabinoid agonists (e.g., THC) dose-dependently decrease locomotor activity and body temperature and produce antinociception and catalepsy. Drugs that produce this tetrad of effects within a limited dose range are likely to function as CB1 receptor agonists. A structure activity relationship study from our laboratory investigating analogs of the CB1 antagonist rimonabant revealed that certain alterations in the 3-substituent of rimonabant’s pyrazole core conferred agonist-like properties in the tetrad. Interestingly, these effects were present in CB1 -/- mice, and were not reversed by rimonabant in wild-type mice. The present study evaluated two novel 3-substituent rimonabant analogs, O-6629 and O-6658 in the …

Phytoremediation Of Pcb Contaminated Soil: Effectiveness And Regulatory Policy, Nathan Pinsker

Theses and Dissertations

The purpose of this paper was to combine available peer-reviewed literature on PCB phytoremediation and make direct comparisons using ANCOVA statistics in order to determine if and what plants are presently a viable option for the remediation of PCB contaminated soils. Pumpkin (Curbita pepo cv Howden) consistently had the top root and shoot concentrations, as well as total plant accumulation. Their consistency shows that they can be reliable in the field and the most viable option. Tall fescue and sedge were also top contenders. Due to the small sample size for many plants and accounting for several confounding variables, very …

Community Classification And Distribution Patterns Of Freshwater Mussels Of Strawberry River, Arkansas, Sujata Poudel, David E. Tenenbaum Ph.D, John L. Harris, Alan D. Christian Ph.D

Interdisciplinary Perspectives: a Graduate Student Research Showcase

The purpose of this study is to determine if there are distinct communities of freshwater mussels in the Strawberry River, Arkansas, and if environmental variables influenced these communities.  The Strawberry River watershed is located in the Ozark Mountains in northcentral Arkansas.  Based on previous studies of interior highland mussels, we expected distinct low, mid, and high order stream mussel communities. Mussels were surveyed from headwaters to mouth and resulted in 38 species from 57 sites.  Environmental variables of land cover, geology, soiltype, and drainage area were calculated at local and subwatershed scale using GIS. Mussel presence/absence and environmental variables were …

Tumor Recognition And Self-Recognition Induce Distinct Transcriptional Profiles In Antigen-Specific Cd4 T Cells, Adam J. Adler

UCHC Articles - Research

Tumors express a wide variety of both mutated and nonmutated Ags. Whether these tumor Ags are broadly recognized as self or foreign by the immune system is currently unclear. Using an autochthonous prostate cancer model in which hemagglutinin (HA) is specifically expressed in the tumor (ProHA × TRAMP mice), as well as an analogous model wherein HA is expressed in normal tissues as a model self-Ag (C3HA^high), we examined the transcriptional profile of CD4 T cells undergoing Ag-specific division. Consistent with our previous data, transfer of Ag-specific CD4 T cells into C3HA^high resulted in a functionally inactivated …
