Ideas About Nature In American Art And Visual Culture, Mark Graham

Faculty Publications

The stories we tell ourselves about nature deeply influence how we attempt to preserve, use, or restore nature as well as practices of art and art education that are concerned with ecological issues (Cronon 1996). Landscapes are culture before they are nature (Schama 1996). Yet, our ideas about wilderness, nature, landscape, and sustainability are fraught with paradox and debate. For example, Darwin’s fundamental assertions about the human relationship to nature continue to spark theological, political and educational controversies. Some environmentalists caution that our consumerist economy will destroy the planet and that we need to return to a less sophisticated technology …

A Potential Tool For Clinicians; Evaluating A Computer-Led Dietary Assessment Method In Overweight And Obese Women During Weight Loss, Adrianne Widaman, Nancy Keim, Dustin Burnett, Beverly Miller, Megan Witbracht, Keith Widaman, Kevin Laugero

Faculty Publications

Many Americans are attempting to lose weight with the help of healthcare professionals. Clinicians can improve weight loss results by using technology. Accurate dietary assessment is crucial to effective weight loss. The aim of this study was to validate a computer-led dietary assessment method in overweight/obese women. Known dietary intake was compared to Automated Self-Administered 24-h recall (ASA24) reported intake in women (n = 45), 19–50 years, with body mass index of 27–39.9 kg/m2. Participants received nutrition education and reduced body weight by 4%–10%. Participants completed one unannounced dietary recall and their responses were compared to actual intake. Accuracy of …

Threshold Concepts And Core Competences In The Library And Information Science (Lis) Domain: Methodologies For Discovery, Virginia Tucker

Faculty Publications

Researchers have used a variety of methodologies for investigating threshold concepts, and this paper considers these approaches for library and information science (LIS) domains. The focus is on specific benefits of constructivist grounded theory for eliciting evidence of core knowledge, and elements of research design for this purpose are discussed, including the importance of collecting experiences from the learners themselves as well as effective protocols for data gathering and analysis through the use of active tasks and semi-structured interviews. The discussion extends to implications of the research design for how it may be applied to thematic analysis more broadly and …

Innovation Among Different Classes Of Software Development Organizations, James Gaskin, Nicholas Berente, Kalle Lyytinen, Gregory Rose

Faculty Publications

Software development organizations (SDOs) innovate in diverse ways. In this paper, based on an extensive review of innovation typologies, we develop a theory‐driven typology of SDO innovator classes. We theorize about the driving forces behind these classes, with specific attention given to knowledge‐based dispositions that relate to the SDO's knowledge‐based competencies in technology appropriation, technology generation, and network intensity within ecological niches. Through a survey of 136 SDOs, which adopted Internet technologies during 1995‐2006, we empirically verify that these classes also determine different ways that SDOs innovate around software services they provide to their clients. Our findings suggest that the …

Neural Networks In Strategic Marketing: Exploring The Possibilities, Kristen Bell Detienne, David H. Detienne

Faculty Publications

A review of the literature indicates that few studies have used artificial neural networks (ANNs) for data analysis in business and marketing research, even though there are many benefits to the use of ANNs. Therefore, this article discusses neural networks (NNs) that can be used in addition to or as an alternative to linear regression for data analysis in strategic marketing. The function and layout of NNs make them ideal for research dealing with nonlinear, incomplete, unspecified, or ‘fuzzy’ data and offer several advantages over linear regression. Unfortunately, in many marketing studies, the information being modeled is far from flawless …

The Relationship Between Family Support; Pain And Depression In Elderly With Arthritis, Wendy C. Birmingham, Man Hung, Jerry Bounsanga, Maren W. Voss, Anthony B. Crum, Wei Chen

Faculty Publications

The prevalence and chronic nature of arthritis make it the most common cause of disability among U.S.A adults. Family support reduces the negative impact of chronic conditions generally but its role in pain and depression for arthritic conditions is not well understood. A total of 844 males (35.0%) and 1567 females (65.0%) with arthritic conditions (n = 2411) were drawn from the 2012 Health and Retirement Study to examine the effect of family support on pain and depressive symptoms. Using regression analysis and controlling for age, ethnicity, gender, marital/educational status and employment/income, physical function/disability status, pain and antidepressant medications, and …

Structural Covariance Of Sensory Networks, The Cerebellum, And Amygdala In Autism Spectrum Disorder, Garrett Cardon, Susan Hepburn, Donald C. Rojas

Faculty Publications

Sensory dysfunction is a core symptom of autism spectrum disorder (ASD), and abnormalities with sensory responsivity and processing can be extremely debilitating to ASD patients and their families. However, relatively little is known about the underlying neuroanatomical and neurophysiological factors that lead to sensory abnormalities in ASD. Investigation into these aspects of ASD could lead to significant advancements in our general knowledge about ASD, as well as provide targets for treatment and inform diagnostic procedures. Thus, the current study aimed to measure the covariation of volumes of brain structures (i.e., structural magnetic resonance imaging) that may be involved in abnormal …

Introduction: Individuals with idiopathic subglottic stenosis (SGS) are at risk for voice disorders prior to and following surgical management. This study examined the nature and severity of voice disorders in patients with SGS before and after a revised cricotracheal resection (CTR) procedure designed to minimize adverse effects on voice function. Method: Eleven women with idiopathic SGS provided presurgical and postsurgical audio recordings. Voice Handicap Index (VHI) scores were also collected. Cepstral, signal-to-noise, periodicity, and fundamental frequency (F0) analyses wereundertaken for connected speech and sustained vowel samples. Listeners made auditory-perceptual ratings of overall qualityand monotonicity.Results: Paired samples statistical analyses revealed that …

Siah2 Protein Mediates Early Events In Commitment To An Adipogenic Pathway, Gail Kilroy, David H. Burk, Z. Elizabeth Floyd

Faculty Publications

© 2016 by The American Society for Biochemistry and Molecular Biology, Inc. Adipose tissue expansion occurs by increasing the size of existing adipocytes or by increasing the number of adipocytes via adipogenesis. Adipose tissue dysfunction in obesity is associated with adipocyte hypertrophy and impaired adipogenesis. We recently demonstrated that deletion of the ubiquitin ligase Siah2 is associated with enlarged adipocytes in lean or obese mice. In this study, we find that adipogenesis is impaired in 3T3-L1 preadipocytes stably transfected with Siah2 shRNA and that overexpression of Siah2 in non-precursor fibroblasts promotes adipogenesis. In the 3T3-L1 model, loss of Siah2 is …

Isotopic Analysis Of Sporocarp Protein And Structural Material Improves Resolution Of Fungal Carbon Sources, Janet Chen, Kirsten S. Hofmockel, Erik A. Hobbie

Faculty Publications

Fungal acquisition of resources is difficult to assess in the field. To determine whether fungi received carbon from recent plant photosynthate, litter or soil-derived organic (C:N bonded) nitrogen, we examined differences in δ13C among bulk tissue, structural carbon, and protein extracts of sporocarps of three fungal types: saprotrophic fungi, fungi with hydrophobic ectomycorrhizae, or fungi with hydrophilic ectomycorrhizae. Sporocarps were collected from experimental plots of the Duke Free-air CO2 enrichment experiment during and after CO2 enrichment. The differential 13C labeling of ecosystem pools in CO2 enrichment experiments was tracked into fungi and provided novel insights into organic nitrogen use. Specifically, …

A Cloud-Based Workflow To Quantify Transcript-Expression Levels In Public Cancer Compendia, P J. Tatlow, Stephen R. Piccolo

Faculty Publications

Public compendia of sequencing data are now measured in petabytes. Accordingly, it is infeasible for researchers to transfer these data to local computers. Recently, the National Cancer Institute began exploring opportunities to work with molecular data in cloud-computing environments. With this approach, it becomes possible for scientists to take their tools to the data and thereby avoid large data transfers. It also becomes feasible to scale computing resources to the needs of a given analysis. We quantified transcript-expression levels for 12,307 RNA-Sequencing samples from the Cancer Cell Line Encyclopedia and The Cancer Genome Atlas. We used two cloud-based configurations and …

Constraining Ribbon Rock Dolomitization By Mg Isotopes: Implications For The ‘Dolomite Problem’, Fang Bing Li, Fang Zhen Teng, Ji Tao Chen, Kang Jun Huang, Shui Jiong Wang, Xian Guo Lang, Hao Ran Ma, Yong Bo Peng, Bing Shen

Faculty Publications

© 2016 Elsevier B.V. Modern dolomite formation is conditional and restricted in specific environmental and geochemical conditions, accordingly cannot be used as the analog of ancient dolostones, which normally have platform-wide distribution. The key to understand ancient dolostone formation is to find a dolomitization process that is independent of physical/geochemical environments. It is well-known that ribbon rock (one type of calcareous rhythmites, sensu stricto referring to the alternating limestone and marlstone layers or the limestone-marl alternations) that are deposited in nearly all marine environments throughout the Earth's history, are exclusively, though normally partially, dolomitized. Thus, understanding ribbon rock dolomitization may …

Transcription Factor Reb1 Is Required For Proper Transcriptional Start Site Usage At The Divergently Transcribed Tfc6-Esc2 Locus In Saccharomyces Cerevisiae, Qing Wang, David Donze

Faculty Publications

© 2016 Elsevier B.V. Eukaryotic promoters generally contain nucleosome depleted regions near their transcription start sites. In the model organism Saccharomyces cerevisiae, these regions are adjacent to binding sites for general regulatory transcription factors, and the Reb1 protein is commonly bound to promoter DNA near such regions. The yeast TFC6 promoter is a unique RNA polymerase II promoter in that it is autoregulated by its own gene product Tfc6p, which is part of the RNA polymerase III transcription factor complex TFIIIC. We previously demonstrated that mutation of a potential Reb1 binding site adjacent to the TFIIIC binding site in the …

Multilevel Perspective On High-Order Harmonic Generation In Solids, Mengxi Wu, Dana A. Browne, Kenneth J. Schafer, Mette B. Gaarde

Faculty Publications

We investigate high-order harmonic generation in a solid, modeled as a multilevel system dressed by a strong infrared laser field. We show that the cutoff energies and the relative strengths of the multiple plateaus that emerge in the harmonic spectrum can be understood both qualitatively and quantitatively by considering a combination of adiabatic and diabatic processes driven by the strong field. Such a model was recently used to interpret the multiple plateaus exhibited in harmonic spectra generated by solid argon and krypton [G. Ndabashimiye, Nature 534, 520 (2016)NATUAS0028-083610.1038/nature17660]. We also show that when the multilevel system originates from the Bloch …

Focusing On Men And Fathers: A Challenge For Social Work Research And Practice, Kevin Shafer, Jennifer L. Bellamy

Faculty Publications

In introducing this special issue of Social Work Research, we feel it is important to discuss why social work practice and research with men and fathers is of critical importance and deserving of specific attention. Social work researchers and practitioners need to focus on men and fathers, both as a special population and as subpopulations of other groups. A focus on men and fathers is critical because (a) it is a social justice issue for men, women, and children; (b) men are underserved by helping professionals, including social workers, particularly in certain contexts and programs; (c) social workers are uniquely …

Peg3 Binds To H19-Icr As A Transcriptional Repressor, An Ye, Hongzhi He, Joomyeong Kim

Faculty Publications

© 2016 Taylor & Francis Group, LLC. Paternally expressed gene 3 (Peg3) encodes a DNA-binding protein with 12 C2H2 zinc finger motifs. In the current study, we performed ChIP-seq using mouse embryonic fibroblast (MEF) cells. This experiment identified a set of 16 PEG3 genomic targets, the majority of which overlapped with the promoter regions of genes with oocyte expression. These potential downstream genes were upregulated in MEF cells lacking PEG3 protein, suggesting a potential repressor role for PEG3. Our study also identified the imprinting control region (ICR) of H19 as a genomic target. According to the results, PEG3 binds to …

A Review Of The Tawny Crazy Ant, Nylanderia Fulva, An Emergent Ant Invader In The Southern United States: Is Biological Control A Feasible Management Option?, Zinan Wang, Lori Moshman, Emily C. Kraus, Blake E. Wilson, Namoona Acharya, Rodrigo Diaz
