Acquisition Of Initial Mental Graphemic Representations By Children At Risk For Literacy Development, Kenn Apel, Shurita Thomas-Tate, Elizabeth B. Wilson-Fowler, Danielle Brimo

Faculty Publications

We examined the acquisition of initial mental graphemic representations (MGRs) by 46 kindergarten children (mean age = 5 years, 9 months) at risk for literacy development because of low socioeconomic status. Using a storybook context, we exposed children to novel nonwords that varied in their phonotactic and orthotactic probabilities and then assessed the children's development of initial MGRs through spelling and reading recognition tasks. The children developed some initial MGRs but less than past reports of children from middle socioeconomic backgrounds. Children with more advanced word recognition abilities developed more initial MGRs than their peers with less advanced word recognition …

Examining The Reuse Of Open Textbooks, John Hilton Iii, David A. Wiley, Neil Lutz

Faculty Publications

An important element of open educational resources (OER) is the permission to use the materials in new ways, including revising and remixing them. Prior research has shown that the revision and remix rates for OER are relatively low. In this study we examined the extent to which the openly licensed Flat World Knowledge textbooks were being revised and remixed. We found that the levels of revision and remix were similar to those of other OER collections. We discuss the possible significance and implication of these findings.

Analysis Of A Kinetic Multi-Segment Foot Model. Part I: Model Repeatability And Kinematic Validity, Dustin A. Bruening, Kevin M. Cooney, Frank L. Buczek

Faculty Publications

Kinematic multi-segment foot models are still evolving, but have seen increased use in clinical and research settings. The addition of kinetics may increase knowledge of foot and ankle function as well as influence multi-segment foot model evolution; however, previous kinetic models are too complex for clinical use. In this study we present a three-segment kinetic foot model and thorough evaluation of model performance during normal gait. In this first of two companion papers, model reference frames and joint centers are analyzed for repeatability, joint translations are measured, segment rigidity characterized, and sample joint angles presented. Within-tester and between-tester repeatability were …

Stress, Mental Health, And Substance Abuse Problems In A Sample Of Diversion Program Youths: An Exploratory Latent Class Analysis, Richard Dembo, Rhissa Briones-Robinson, Laura M. Gulledge, Lora M. Karas, Ken C. Winters, Steven Belenko, Paul Greenbaum

Faculty Publications

Reflective of interest in mental health and substance abuse issues among youths involved with the justice system, we performed a latent class analysis on baseline information collected on 100 youths involved in two diversion programs. Results identified two groups of youths: Group 1: a majority of the youths, who had high levels of delinquency, mental health, and substance abuse issues; and Group 2: youths with low levels of these problems. Comparison of these two groups on a variety of psychosocial measures and parent/guardian reports found differences between them that were consistent with their problem group classification. Follow-up analysis confirmed problem …

Phosphorus (P) is a critical driver of phytoplankton growth and ecosystem function in the ocean. Diatoms are an abundant class of marine phytoplankton that are responsible for significant amounts of primary production. With the control they exert on the oceanic carbon cycle, there have been a number of studies focused on how diatoms respond to limiting macro and micronutrients such as iron and nitrogen. However, diatom physiological responses to P deficiency are poorly understood. Here, we couple deep sequencing of transcript tags and quantitative proteomics to analyze the diatom Thalassiosira pseudonana grown under P-replete and P-deficient conditions. A total of …

Ototoxic Hearing Loss And Retinoblastoma Patients, Shaum Bhagat

Faculty Publications

Chemotherapy is often used in the conservative management of retinoblastoma. Chemotherapy drugs, while ameliorative, can produce long-lasting side effects that potentially can affect survivor quality of life. Carboplatin is a common chemotherapy agent with known ototoxic side effects that is used in the treatment of retinoblastoma (Rodriguez-Galindo et al., 2003). The potential for carboplatin-induced hearing loss is of concern to the medical professional, given that retinoblastoma is often diagnosed in early childhood and children with retinoblastoma have visual impairments. This chapter will outline the mechanisms underlying carboplatin ototoxicity. The extent of knowledge concerning the pathophysiology of carboplatin-induced hearing loss will …

Reactive Oxygen Species And Mitochondrial Sensitivity To Oxidative Stress Determine Induction Of Cancer Cell Death By P21, Ionica Masgras, Samantha Carrera, Petra J. De Verdier, Paul Brennan, Aneela Majid, Wan Makhtar, Eugene Tulchinsky, George D. Jones, Igor Roninson, Salvador Macip

Faculty Publications

p21(Waf1/Cip1/Sdi1) is a cyclin-dependent kinase inhibitor that mediates cell cycle arrest. Prolonged p21 up-regulation induces a senescent phenotype in normal and cancer cells, accompanied by an increase in intracellular reactive oxygen species (ROS). However, it has been shown recently that p21 expression can also lead to cell death in certain models. The mechanisms involved in this process are not fully understood. Here, we describe an induction of apoptosis by p21 in sarcoma cell lines that is p53-independent and can be ameliorated with antioxidants. Similar levels of p21 and ROS caused senescence in the absence of significant death in other cancer …

Self-Assembly Of Octadecyltrichlorosilane: Surface Structures Formed Using Different Protocols Of Particle Lithography, Cha Marra K. Saner, Kathie L. Lusker, Zorabel M. Lejeune, Wilson K. Serem, Jayne C. Garno

Faculty Publications

Particle lithography offers generic capabilities for the high-throughput fabrication of nanopatterns from organosilane self-assembled monolayers, which offers the opportunity to study surface-based chemical reactions at the molecular level. Nanopatterns of octadecyltrichlorosilane (OTS) were prepared on surfaces of Si(111) using designed protocols of particle lithography combined with either vapor deposition, immersion, or contact printing. Changing the physical approaches for applying molecules to masked surfaces produced OTS nanostructures with different shapes and heights. Ring nanostructures, nanodots and uncovered pores of OTS were prepared using three protocols, with OTS surface coverage ranging from 10% to 85%. Thickness measurements from AFM cursor profiles were …

Β-Nitro Derivatives Of Iron Corrolates, Sara Nardis, Manuela Stefanelli, Pruthviraj Mohite, Giuseppe Pomarico, Luca Tortora, Machima Manowong, Ping Chen, Karl M. Kadish, Frank R. Fronczek, Gregory T. Mccandless, Kevin M. Smith, Roberto Paolesse

Faculty Publications

Two different methods for the regioselective nitration of different meso-triarylcorroles leading to the corresponding β-substituted nitrocorrole iron complexes have been developed. A two-step procedure affords three Fe(III) nitrosyl products-the unsubstituted corrole, the 3-nitrocorrole, and the 3,17-dinitrocorrole. In contrast, a one-pot synthetic approach drives the reaction almost exclusively to formation of the iron nitrosyl 3,17-dinitrocorrole. Electron-releasing substituents on the meso-aryl groups of the triarylcorroles induce higher yields and longer reaction times than what is observed for the synthesis of similar triarylcorroles with electron-withdrawing functionalities, and these results can be confidently attributed to the facile formation and stabilization of an intermediate iron …

Coral reefs are experiencing unprecedented degradation due to human activities, and protecting specific reef habitats may not stop this decline, because the most serious threats are global (i.e., climate change), not local. However, ex situ preservation practices can provide safeguards for coral reef conservation. Specifically, modern advances in cryobiology and genome banking could secure existing species and genetic diversity until genotypes can be introduced into rehabilitated habitats. We assessed the feasibility of recovering viable sperm and embryonic cells post-thaw from two coral species, Acropora palmata and Fungia scutaria that have diffferent evolutionary histories, ecological niches and reproductive strategies. In vitro …

A Religious Organization’S Autonomy In Matters Of Self-Governance: Hosanna-Tabor And The First Amendment, Carl H. Esbeck

Faculty Publications

In Hosanna-Tabor, a teacher suing her employer, a church-based school, alleged retaliation for having asserted rights under a discrimination statute. The School raised the “ministerial exception,” which prohibits ministers from suing their religious employer. The Court held the exception was constitutionally required. Before giving the facts that convinced it that this teacher was a “minister,” the Court had to distinguish the leading case of Employ. Div. v. Smith. Plaintiffs in Smith held jobs as counselors at a drug rehabilitation center. They were fired for illegal drug use (peyote), and later denied unemployment compensation. The Native American Church ingests peyote during …

Detection And Imaging Of The Free Radical Dna In Cells—Site-Specific Radical Formation Induced By Fenton Chemistry And Its Repair In Cellular Dna As Seen By Electron Spin Resonance, Immuno-Spin Trapping And Confocal Microscopy, Suchandra Bhattacharjee, Saurabh Chatterjee, Jinjie Jiang, Birandra K. Sinha, Ronald P. Mason

Faculty Publications

Oxidative stress-related damage to the DNA macromolecule produces lesions that are implicated in various diseases. To understand damage to DNA, it is important to study the free radical reactions causing the damage. Measurement of DNA damage has been a matter of debate as most of the available methods measure the end product of a sequence of events and provide limited information on the initial free radical formation. We report a measurement of free radical damage in DNA induced by a Cu(II)-H2O2 oxidizing system using immuno-spin trapping supplemented with electron paramagnetic resonance. In this investigation, the short-lived radical generated is trapped …

Competitiveness And Individualism-Collectivism In Bali And The U.S., John M. Houston, Cokorda Bagus Jaya Lesmana, Luh Ketut Suryani Udayana University

Faculty Publications

Competitiveness is an important individual difference variable that influences behavior across a range of social domains; however, surprisingly few studies have examined competitiveness from a cross-cultural perspective. This study examined the relationship betweendifferent aspects of competitiveness and individualism-collectivism as individual difference variables in two cultures by comparing Balinese (n = 104) and American (n = 124) undergraduate college students. The results indicated that healthy competitiveness was positively related to collectivism for both Balinese and American students; however, unhealthy competitiveness or hypercompetitiveness was only negatively related to collectivism for Balinese students.

Middle Income Peers As Educational Resources And The Constitutional Right To Equal Access, Derek W. Black

Faculty Publications

Concentrated poverty in public schools continues to be a leading determinate of the educational opportunities that minority students receive. Since the effective end of mandatory desegregation, advocates have lacked legal tools to address it. As an alternative, some advocates and scholars have attempted to incorporate the concerns of concentrated poverty and racial segregation into educational litigation under state constitutions, but these efforts have been slow to take hold. Thus, all that has remained for students in poor and minority schools is the hope that school finance litigation could direct sufficient resources to mitigate their plight. This Article offers another solution. …

Drug Treatment Program Ownership, Medicaid Acceptance, And Service Provision., Duane C. Mcbride, J. Chriqui, Y. Terry-Mcelrath, M Mulatu

Faculty Publications

The Institute of Medicine noted that effective substance abuse treatment (SAT) programs integrate individual therapeutic approaches with transitional/ancillary services. In addition, research suggests that type of ownership impacts SAT services offered and that Medicaid plays a key role in SAT access. Data from the National Survey of Substance Abuse Treatment Services for the years 2000 and 2002–2006 were used to examine relationships among SAT program Medicaid acceptance, program ownership, and transitional/ancillary service accessibility. Multivariate logistic regression models controlling for state- and program-level contextual factors were used to analyze the data. Nonprofit SAT programs were significantly more likely to offer transitional/ancillary …

Influence Of Immobilized Biomolecules On Magnetic Bead Plug Formation And Retention In Capillary Electrophoresis, Rachel L. Henken, Rattikan Chantiwas, S. Douglass Gilman

Faculty Publications

Significant changes in the formation and retention of magnetic bead plugs in a capillary during electrophoresis were studied, and it was demonstrated that these effects were due to the type of biological molecule immobilized on the surface of these beads. Three biological molecules, an antibody, an oligonucleotide, and alkaline phosphatase (AP), were attached to otherwise identical streptavidin-coated magnetic beads through biotin-avidin binding in order to isolate differences in bead immobilization in a magnetic field resulting from the type of biological molecule immobilized on the bead surface. AP was also attached to the magnetic beads using epoxy groups on the bead …

Life, Transferable: Questioning The Commodity-Based Approach To Transplantation Ethics, David Dillard-Wright

Faculty Publications

Some bioethicists have proposed a legalized market in human organs as a solution to transplant waiting lists and global poverty. Solutions to organ procurement problems that are solely market-based would unfairly shift the burdens of medical procedures onto developing nations. Market advocates base their claims on the understanding of organs as property, a position that should be problematized. Instrumentalizing people in this way is made part of the broader commodification of animals and the environment. Combating the market mentality requires a return to the holistic view of bioethics that led to the founding of the field.

Tolerance, Fermentation, And Cytokine Expression In Healthy Aged Male C57bl/6j Mice Fed Resistant Starch, June Zhou, Michael J. Keenan, Jeffrey Keller, Sun O. Fernandez-Kim, Paul J. Pistell, Richard T. Tulley, Anne M. Raggio, Li Shen, Hanjie Zhang, Roy J. Martin, Marc R. Blackman

Faculty Publications

Health benefits of resistant starch (RS), a dietary fermentable fiber, have been well documented in young, but not in old populations. As the essential step of more comprehensive evaluations of RS on healthy aging, we examined the effects of dietary RS on tolerance, colonic fermentation, and cytokine expression in aged mice. Healthy older (18-20 months) C57BL/6J male mice were fed control, 18% RS, or 36% RS diets for 10weeks. Body weight gain, body composition, and fat pad weights did not differ among the three groups after 10weeks, indicating good tolerance of the RS diet. Fermentation indicators (cecum weights, and cecal …

Section 2 Enforcement And The Great Recession: Why Less (Enforcement) Might Mean More (Gdp), Alan J. Meese

Faculty Publications

The Great Recession has provoked calls for more vigorous regulation in all sectors, including antitrust enforcement. After President Obama took office, the Antitrust Division of the Department of Justice abandoned the Bush Administration’s standard of liability under section 2 of the Sherman Act, which forbids unlawful monopolization, as insufficiently interventionist. Based on the premise that similarly lax antitrust enforcement caused and deepened the Great Depression, the Obama Administration outlined a more intrusive and consumer-focused approach to section 2 enforcement as part of a larger national strategy to combat the “extreme” economic crisis the nation was then facing.

Securing Civil Protection Orders For Teens When Laws Ignore Teens, Lisa V. Martin

Faculty Publications

Despite the pervasiveness of violence in teen relationships, civil protection order statutes largely ignore teens. The accessibility of protection orders for teens depends primarily on the scope of their rights to standing and legal capacity to pursue claims for protection. Because states largely fail to detail expressly the circumstances under which teens are accorded standing to seek protection orders and legal capacity to represent their own interests in related court proceedings, the accessibility of protection orders for teens in most states remains in flux.

This article explores legal principles and policy arguments that support the extension of standing and legal …

Pathos: A Brief Screening Application For Assessing Sexual Addiction, Patrick J. Carnes, Bradley A. Green, Lisa J. Merlo, Alexis Polles, Mark S. Gold

Faculty Publications

Sexual addiction is estimated to afflict up to 3% to 6% of the population. However, many clinicians lack clear criteria for detecting potential cases.

Objectives: The present studies were conducted to assess the effectiveness of a brief sexual addiction screening instrument (ie, PATHOS Questionnaire) to correctly classify patients being treated for sex addiction and healthy volunteers.

Methods: In study 1, a 6-item questionnaire, which utilizes the mnemonic "PATHOS," was examined in regard to sensitivity and specificity using a sample combining patients being treated for sex addiction and healthy volunteers (970 men/80.2% patients; 938 women/63.8% patients). In study 2, a cross-validation …

School Racial Composition And Race/Ethnic Differences In Early Adulthood Health, Bridget J. Goosby, Katrina M. Walsemann

Faculty Publications

We investigate whether school racial composition is associated with racial and ethnic differences in early adult health. We then examine whether perceived discrimination, social connectedness, and parent support attenuates this relationship. Using U.S. data from Wave I and IV of the National Longitudinal Survey of Adolescent Health, we found that black adolescents attending predominantly white schools reported poorer adult health while Asians reported better health. Further research is warranted to understand whether there are qualitative differences in the treatment of racial and ethnic minorities within certain school contexts and how that differential treatment is related to adult health outcomes.
