Bounds And Conditions: A Kolob In Our Solar System?, David D. Allred

Faculty Publications

In 2003, Dialogue ran adjacent essays by two scientists, David Tolman and David Allred. The two Davids had been students together at Princeton, attending the same student ward. Decades after Princeton, Tolman had left Mormonism and Allred had stayed. Their essays are a fascinating juxtaposition. In the course of his piece, David Allred ventured for a few paragraphs into a discussion of the planet Jupiter and its role as a governor and protector in our solar system—a type of Kolob. Although the other author dismissed the topic as “fanciful physics,” my own interest was piqued. I asked Dr. Allred, who …

Post-Traumatic Stress Disorder And Post-Traumatic Stress Symptoms Following Critical Illness In Medical Intensive Care Unit Patients: Assessing The Magnitude Of The Problem, Ramona O. Hopkins, James C. Jacson, Robert P. Hart, Sharon M. Gordon, Timothy D. Girard, E. Wesley Ely

Faculty Publications

Post-traumatic stress disorder (PTSD) is a potentially serious psychiatric disorder that has traditionally been associated with traumatic stressors such as participation in combat, violent assault, and survival of natural disasters. Recently, investigators have reported that the experience of critical illness can also lead to PTSD, although details of the association between critical illness and PTSD remain unclear. Methods We conducted keyword searches of MEDLINE and Psych Info and investigations of secondary references for all articles pertaining to PTSD in medical intensive care unit (ICU) survivors. Results: From 78 screened papers, 16 studies (representing 15 cohorts) and approximately 920 medical ICU …

Evaluating The Impact On Users From Implementing A Course Management System, Charles R. Graham, Meghan M. Kennedy, Gregory L. Waddoups, Richard E. West

Faculty Publications

Nearly all colleges and universities are using some form of e-learning system, usually an expensive course management system (CMS), to create online course offerings or to enhance regular, classroom-oriented courses. Our university has invested a large amount of resources into purchasing and supporting one of the two most popular CMS vendors, and it has become imperative to understand what the effects from using this technology have been, as well as how we can improve the integration of this and other educational technologies into different instructional contexts. This project, through a combination of surveys, call-log analysis, and interviews, was used to …

Two Sides Of The Same Coin? The Differing Roles Of Assets And Consumer Debt In Marriage, Jeffrey P. Dew

Faculty Publications

This study examines whether assets and consumer debts relate to change in marital satisfaction and conflict in opposing ways or in independent ways. It also tests whether these relationships are direct or mediated. Using a nationally representative longitudinal sample, the results indicate that assets and consumer debt influence change in marital outcomes in mostly independent rather than complementary ways. Consistent with prior literature, assets work indirectly by decreasing feelings of economic pressure. Consumer debt, however, directly predicts changes in marital conflict, even after controlling for variables in the family stress model. Debts also act indirectly by decreasing depression once economic …

Family Support For Physical Activity In Girls From 8th To 12th Grade In South Carolina, Marsha Dowda, Rod K. Dishman, Karin A. Pfeiffer, Russell R. Pate

Faculty Publications

Objective - To examine the relationship between perceived family support and other selected correlates of physical activity (PA) with changes in PA over time.

Methods - A total of 421 girls in South Carolina completed questionnaires at 8th, 9th and 12th grades (1998-2003). Family support for PA, PA self-efficacy, perceived behavioral control, attitudes, availability of equipment, and PA were measured.

Results - Growth curve analysis showed that family support, perceived behavioral control, and self-efficacy were independently related to age-related changes in PA as reflected by a total METs. Girls who reported lower family support at the 8th grade measure had …

Yy1 As A Controlling Factor For The Peg3 And Gnas Imprinted Domains, Jeong Do Kim, Angela K. Hinz, Jung Ha Choo, Lisa Stubbs, Joomyeong Kim

Faculty Publications

Imprinting control regions (ICRs) often harbor tandem arrays of transcription factor binding sites, as demonstrated by the identification of multiple YY1 binding sites within the ICRs of Peg3, Nespas, and Xist/Tsix domains. In the current study, we have sought to characterize possible roles for YY1 in transcriptional control and epigenetic modification of these imprinted domains. RNA interference-based knockdown experiments in Neuro2A cells resulted in overall transcriptional up-regulation of most of the imprinted genes within the Peg3 domain and also, concomitantly, caused significant loss in the DNA methylation of the Peg3 differentially methylated region. A similar overall and coordinated expression change …

Generation And Characterization Of Rabbit Embryonic Stem Cells, Shufen Wang, Xianghui Tang, Yuyu Niu, Hongwei Chen, Bin Li, Tianqing Li, Xiuzhen Zhang, Zhixin Hu, Qi Zhou, Weizhi Ji

Faculty Publications

We described the derivation of four stable pluripotent rabbit embryonic stem cell (ESC) lines, one (RF) from blastocysts fertilized in vivo and cultured in vitro and three (RP01, RP02, and RP03) from parthenogenetic blastocysts. These ESC lines have been cultivated for extended periods (RF >1 year, RP01 >8 months, RP02 >8 months, and RP03 >6 months) in vitro while maintaining expression of pluripotent ESC markers and a normal XY or XX karyotype. The ESCs from all lines expressed alkaline phosphatase, transcription factor Oct-4, stage-specific embryonic antigens (SSEA-1, SSEA-3, and SSEA-4), and the tumor-related antigens (TRA-1-60 and TRA-1-81). Similar to human …

Laguerre Functions On Symmetric Cones And Recursion Relations In The Real Case, Michael Aristidou, Mark Davidson, Gestur Ólafsson

Faculty Publications

In this article we derive differential recursion relations for the Laguerre functions on the cone Ω of positive definite real matrices. The highest weight representations of the group Sp (n, R) play a fundamental role. Each such representation acts on a Hilbert space of holomorphic functions on the tube domain Ω + i Sym (n, R). We then use the Laplace transform to carry the Lie algebra action over to L2 (Ω, d μν). The differential recursion relations result by restricting to a distinguished three-dimensional subalgebra, which is isomorphic to sl (2, R) . © 2005 Elsevier B.V. All rights …

Faculty Publications

The Physical Activity Questionnaire for Older Children (PAQ-C) is a validated self-report measure of physical activity widely used to assess physical activity in children (8-14 years of age). To date, however, the instrument has been validated in largely White Canadian samples. The purpose of the present article is to determine the pscyhometric properties of the PAQ-C for African American, European American, and Hispanic children. Two studies were conducted in which independent samples were administered the PAQ-C, along with varying indices of cardiovascular fitness, fatness, and psychological measures related to physical activity. Results showed that the reliability and validity of the …

Threshold Power Of Canonical Antennas For Inducing Sar At Compliance Limits In The 300-3000 Mhz Frequency Range, Mohammod Ali, Mark G. Douglas, Abu T.M. Sayem, Antonio Faraone, Chung-Kwang Chou

Faculty Publications

A study of the specific absorption rate (SAR) in an exposed body induced by canonical antennas is presented, with the aim of determining an upper bound for the antenna transmit power that demonstrates that a product is inherently compliant with internationally accepted radio frequency (RF) exposure limits. Starting from the fundamental limits in antenna quality factor (Q) and the corresponding bandwidth, several antenna sizes are selected, and their SAR distributions are computed using the method of moments (MoM) and finite-difference time domain (FDTD) method in the frequency range 300-3000 MHz. The threshold powers are then determined, below which the peak …

A Dairy-Based Espresso Beverage Manufactured Using Three Different Coffee Bean Roasts, Charles A. Boeneke, John U. Mcgregor, Kayanush J. Aryana

Faculty Publications

The objective of this study was to evaluate the effects of coffee bean roast on the acceptability of a dairy-based espresso drink. Espresso coffee was made from freshly ground coffee beans with light-medium roast, between roast (between medium and dark) and dark French roast in order to show the influence of roasting on flavor. Samples were prepared by blending skim milk, soft-serve ice cream mix, ice and fresh espresso extracts. No significant differences (P < 0.05) were detected in total solids and fat content among treatments. Viscosity for the light-medium roasted beverage was significantly (P < 0.05) higher than the others. The beverage pH increased with increased darkening of roast. The beverage made with the light-medium roasted coffee had significantly (P < 0.05) higher preference scores for coffee flavor and overall flavor than beverages made with the between and French roasts. The between and French roasted treatments were shown to have a more intense coffee flavor by trained sensory panelists. Consumers in this study preferred a less intense coffee flavor. © 2007, Blackwell Publishing.

Food Insecurity And Subsequent Weight Gain In Women, Sonya J. Jones, Edward A. Frongillo Jr.

Faculty Publications

Objective: Cross-sectional data indicate that a relationship between household food insecurity and overweight exists among women in the USA. Cross-sectional data cannot determine if food insecurity leads to overweight as some have hypothesised. The purpose of the present study was to examine the relationship of food insecurity with subsequent weight gain in women using data from the Panel Study of Income Dynamics (PSID).

Design, setting and subjects:Panel data from the 1999 and 2001 PSID, a nationally representative sample of households, were analysed using multivariate regression procedures.

Results: Average weight gain among all women (n=5595) was 1.1 kg …

Avpv Neurons Containing Estrogen Receptor-Beta In Adult Male Rats Are Influenced By Soy Isoflavones, Edwin D. Lephart, Lihong H. Bu

Faculty Publications

Background Isoflavones, the most abundant phytoestrogens in soy foods, are structurally similar to 17beta-estradiol. It is known that 17beta-estradiol induces apoptosis in anteroventral periventricular nucleus (AVPV) in rat brain. Also, there is evidence that consumption of soy isoflavones reduces the volume of AVPV in male rats. Therefore, in this study, we examined the influence of dietary soy isoflavones on apoptosis in AVPV of 150 day-old male rats fed either a soy isoflavone-free diet (Phyto-free) or a soy isoflavone-rich diet (Phyto-600). Results: The occurrence of apoptosis in AVPV was examined by TUNEL staining. The incidence of apoptosis was about 10 times …

Because of this attention, it is desirable to present a survey of HRI to serve as a tutorial to people outside the field and to promote discussion of a unified vision of HRI within the field. The goal of this review is to present a unified treatment of HRI-related problems, to identify key themes, and discuss challenge problems that are likely to shape the field in the near future. Although the review follows a survey structure, the goal of …

Bereavement In The Modern Western World, David San Filippo Ph.D.

Faculty Publications

Bereavement is the process of suffering that follows the loss of a living being that is significant to someone. When one suffers, she or he has to endure an unpleasant experience, in the case of bereavement, the loss of something special to the person. This loss most often is a loved one but could also include the loss of a pet, relationship, or physical or mental capability. This state of suffering is called grief. In describing his grief, C. S. Lewis stated, after the loss of his wife, “No one ever told me that grief felt so much like fear. …

Model-Based Compartmental Analysis Indicates A Reduced Mobilization Of Hepatic Vitamin A During Inflammation In Rats, Sin Gieng, Michael Green, Joanne Green, Francisco Rosales

Faculty Publications

Vitamin A (VA) kinetics was studied in rats with marginal VA stores before, during, and after inflammation. Rats received orally [11,12-3H(N)]retinol ([3H]VA; day 0), and inflammation was induced on day 21 with lipopolysacchride (LPS) for 3 days (n = 5) or recombinant human interleukin-6 (rhIL-6) for 7 days (n = 5). Both the fraction of [3H]VA and retinol concentrations in plasma were reduced significantly by LPS or rhIL-6. Compartmental analysis using the Windows version of Simulation, Analysis, and Modeling software was applied to group mean data, and non-steady-state models were developed. After absorption, VA kinetics was described by a three-compartment …

Self-Archiving And The Copyright Transfer Agreements Of Isi-Ranked Library And Information Science Journals, Anita Coleman

Faculty Publications

A study of Thomson-Scientific ISI ranked Library and Information Science (LIS) journals (n = 52) is reported. The study examined the stances of publishers as expressed in the Copyright Transfer Agreements (CTAs) of the journals toward self-archiving, the practice of depositing digital copies of one's works in an Open Archives Initiative (OAI)-compliant open access repository. Sixty-two percent (32) do not make their CTAs available on the open Web; 38% (20) do. Of the 38% that do make CTAs available, two are open access journals. Of the 62% that do not have a publicly available CTA, 40% are silent about self-archiving. …

Smith, Robert E. Berry, Nikolai V. Shokhirev, Celia A. Balfour, Hongjun Zhang, F. Ann Walker

Faculty Publications

In this work, we report the assignment of the majority of the ferriheme resonances of high-spin nitrophorins (NPs) 1 and 4 and compare them to those of NP2, published previously. It is found that the structures of the ferriheme complexes of NP1 and NP4, in terms of the orientation of the histidine imidazole ligand, can be described with good accuracy by NMR techniques and that the angle plot proposed previously for the high-spin form of the NPs (Shokhireva, T. Kh.; Shokhirev, N. V.; Walker, F. A. Biochemistry 2003, 42, 679-693) describes the angle of the effective nodal plane of the …

Engagement Risk: Perceptions And Strategies From Audit Partners, Jack R. Ethridge, Treba Marsh, Bonnie Revelt

Faculty Publications

The audit function creates several important relationships among the various parties. One of the significant and potentially problematic relationships is between the audit firm and the audit client. The decision by the audit firm to accept or retain a client is crucial because of the potential risk of being associated with certain clients. The potential damage can range from financial loss and/or loss of prestige to the ultimate demise of the audit firm. Engagement risk is considered to be composed of three components: entity’s business risk, audit risk, and auditor’s business risk. This research questioned whether audit firms have significantly …

Selective Cholesterol Dynamics Between Lipoproteins And Caveolae/Lipid Rafts, Stephen M. Storey, Adalberto M. Gallegos, Barbara P. Atshaves, Avery L. Mcintosh, Gregory G. Martin, Rebecca D. Parr, Kerstin K. Landrock, Ann B. Kier, Judith M. Ball, Friedhelm Schroeder

Faculty Publications

Although low-density lipoprotein (LDL) receptor-mediated cholesterol uptake through clathrin-coated pits is now well understood, the molecular details and organizing principles for selective cholesterol uptake/efflux (reverse cholesterol transport, RCT) from peripheral cells remain to be resolved. It is not yet completely clear whether RCT between serum lipoproteins and the plasma membrane occurs primarily through lipid rafts/caveolae or from non-raft domains. To begin to address these issues, lipid raft/caveolae-, caveolae-, and non-raft-enriched fractions were resolved from purified plasma membranes isolated from L-cell fibroblasts and MDCK cells by detergent-free affinity chromatography and compared with detergent-resistant membranes isolated from the same cells. Fluorescent sterol …

Faculty Publications

The mechanism of heel pressure ulcers after hip surgery is not entirely understood. The purpose of this one-group, prospective, repeated-measures design study was to examine how the external pressure of the bed surface affects heel skin oxygen tension in adults on the first 3 days after hip surgery. Transcutaneous oxygen sensors were placed on the plantar surface of each foot, close to the heels. Measures were taken on room air and with an oxygen challenge with the heels (1) suspended above the bed surface (preload), (2) on the bed surface for 15 minutes (loading), and (3) again suspended above the …

Tackling The Monday Morning Quarterback: Applications Of Hindsight Bias In Decision-Making Settings, T. A. Louie, Mahesh N. Rajan, Robert E. Sibley

Faculty Publications

Extant research has focused largely on what causes hindsight distortion. In contrast, this work examines applied aspects related to the bias in decision-making environments. A conceptual framework is provided and recent real–world examples are presented to outline how decision makers—and those who observe them—show hindsight effects. Then, both negative and positive consequences of the bias are outlined. Strategies are presented to reduce negative effects that occur when decision makers show hindsight distortion. Finally, because it is often not possible to avoid or to correct others' hindsight–tainted evaluations, suggestions for coping with the bias are discussed.

A New N-Terminal Recognition Domain In Caveolin-1 Interacts With Sterol Carrier Protein-2 (Scp-2), Rebecca D. Parr, Gregory G. Martin, Heather A. Hostetler, Megan E. Schroeder, Kiran D. Mir, Ann B. Kier, Judith M. Ball, Friedhelm Schroeder

Faculty Publications

Although plasma membrane domains, such as caveolae, provide an organizing principle for signaling pathways and cholesterol homeostasis in the cell, relatively little is known regarding specific mechanisms, whereby intracellular lipid-binding proteins are targeted to caveolae. Therefore, the interaction between caveolin-1 and sterol carrier protein-2 (SCP-2), a protein that binds and transfers both cholesterol and signaling lipids (e.g., phosphatidylinositides and sphingolipids), was examined by yeast two-hybrid, in vitro binding and fluorescence resonance energy transfer (FRET) analyses. Results of the in vivo and in vitro assays identified for the first time the N-terminal amino acids (aa) 1−32 amphipathic α helix of SCP-2 …
