Selective Mutism: Identification Of Subtypes And Influence On Treatment, Christy A. Mulligan Jan 2012

Selective Mutism: Identification Of Subtypes And Influence On Treatment, Christy A. Mulligan

PCOM Psychology Dissertations

Selective Mutism (SM) is a psychiatric disorder with a relatively low incidence that impairs social communication in some settings. There are many characteristics that appear similar in some children but are absent in others. Therefore, it was hypothesized that there may be distinct SM subtypes that warrant differential diagnosis and treatment strategies. In this study, 442 Selective Mutism Comprehensive Diagnostic Questionnaires (SM-CDQ) were analyzed to help identify children with specific characteristics that made their SM unique. Participants ranged in age from 3 to18 years old and met criteria for SM. The data were coded based on 203 variables and were …

Sensory Processing In Children With Adhd: A Classroom Study And Rational Item Analysis, Jason Mathison Jan 2012

Sensory Processing In Children With Adhd: A Classroom Study And Rational Item Analysis, Jason Mathison

PCOM Psychology Dissertations

In the classroom, distinguishing between sensory modulation disorder (SMD), one proposed subtype of Sensory Processing Disorder, and attention deficit hyperactivity disorder (ADHD) can be difficult given their similar behavioral manifestations. The overlap between these two disorders and the prevelance of rating scales used for gathering diagnostic information warrant a closer look at items on commonly used rating scales to ensure discriminative validity. This pilot study examined specific patterns of SMD in 24 children with ADHD using the Sensory Profile School Companion (SPSC), which includes four components of SMD, namely, Seeking, Avoiding, Registration, and Sensitivity. As hypothesized, the majority of teacher …

Clinician Factors In Psychotherapy Disparities For People With Intellectual Disabilities And Co-Occurring Mental Illness, Timothy Barksdale Jan 2012

Clinician Factors In Psychotherapy Disparities For People With Intellectual Disabilities And Co-Occurring Mental Illness, Timothy Barksdale

PCOM Psychology Dissertations

An estimated 4.5 million Americans with intellectual disabilities (ID) have lived in the community for over twenty years now, following the closing of institutions that once isolated them from the public (Scott, Lakin & Larson, 2008). It has since become evident that this group has the same and more vulnerabilities of developing mental illness than the general public but often lack access to therapeutic service (Whitaker & Read, 2005). Unfortunately society’s lack of interaction with and education about this population has contributed to a number of misconceptions and fears. The hypothesized variables for the behavioral health disparity included: level of …

Attention To Psychosocial Concerns Related To Lqts: A Survey Of Medical Providers, Elizabeth Conlin

PCOM Psychology Dissertations

Long QT Syndrome (LQTS) is a heritable condition characterized by syncopal episodes, arrhythmias, and sudden cardiac death in otherwise healthy individuals. Current research, although underrepresented, on the quality of life and psychosocial stressors indicate that some individuals experience depression and anxiety as a result of this chronic medical illness. A survey was created and administered to cardiologists and allied professionals, who offer medical services to LQTS patients, and belong to the Pediatric Arrhythmia and Congenital Electrophysiology Society (PACES). A Likert scale survey was developed for selfadministration and posted in an email for PACES members to complete voluntarily. This survey study …

Overweight, Obesity, And Mental Illnesses: Weight Loss Treatment, Michelle Huang Jan 2012

Overweight, Obesity, And Mental Illnesses: Weight Loss Treatment, Michelle Huang

PCOM Psychology Dissertations

For the past 30 years, overweight and obesity has increased at alarming rates in the general population. This public health crisis has affected persons with mental illnesses as it has those in the general population. Little is known about how individuals with psychiatric problems respond to weight-loss treatment compared to the general population. The current study examines the efficacy of a cognitive-behavioral group weight-loss intervention with such individuals. The study also examines self-esteem, motivation, and the involvement of a support person in treatment as predictor variables. The treatment was shown to be effective regardless of depression severity. However, while all …

Novel Mechanism Leading To Mismatch Repair Deficiency And Mutator Phenotype, Janice Ortega Rodríguez Jan 2012

Novel Mechanism Leading To Mismatch Repair Deficiency And Mutator Phenotype, Janice Ortega Rodríguez

Theses and Dissertations--Toxicology and Cancer Biology

DNA mismatch repair (MMR) is a critical genome-maintenance system. It ensures genome stability by correcting mismatches generated during DNA replication, suppressing homologous recombination, and inducing apoptosis in response to severe DNA damage. As a result, defects in MMR lead to genome-wide mutations and susceptibility to both hereditary and sporadic cancer syndromes. The hallmark of cancer cells defective in MMR is their ability to display frequent instability in simple repetitive DNA sequences, a phenomenon called microsatellite instability (MSI). However, only ~70% of the MSI-positive tumors have identifiable MMR gene mutations, indicating that additional factor(s) are responsible for the MSI phenotype in …

Relationships Between Telomeric Sequences And Structures, Dna Replication, And The Function Of The Werner Syndrome Protein, Deanna Edwards Jan 2012

Relationships Between Telomeric Sequences And Structures, Dna Replication, And The Function Of The Werner Syndrome Protein, Deanna Edwards

Theses and Dissertations--Toxicology and Cancer Biology

All human chromosomes end with protective structures called telomeres, which consist of thousands of double-stranded TTAGGG repeats and end in a 3’ guanine-rich overhang. These structures shorten normally during each round of replication, and extremely short telomeres along with telomere dysfunction are thought to contribute to the development of aging and cancer. Although many proteins have roles in telomere maintenance, WRN, which is a 3’ to 5’ helicase that is deficient in the premature aging disorder Werner’s syndrome, has been proposed to play multiple roles at telomeres. In this study, I focus on the effect of telomeric sequences and/or structures …

The Polarizing Impact Of Science Literacy And Numeracy On Perceived Climate Change Risks, Donald Braman, Dan M. Kahan, Ellen Peters, Maggie Wittlin, Paul Slovic, Lisa Larrimore Ouellette, Gregory N. Mandel Jan 2012

The Polarizing Impact Of Science Literacy And Numeracy On Perceived Climate Change Risks, Donald Braman, Dan M. Kahan, Ellen Peters, Maggie Wittlin, Paul Slovic, Lisa Larrimore Ouellette, Gregory N. Mandel

GW Law Faculty Publications & Other Works

Seeming public apathy over climate change is often attributed to a deficit in comprehension. The public knows too little science, it is claimed, to understand the evidence or avoid being misled. Widespread limits on technical reasoning aggravate the problem by forcing citizens to use unreliable cognitive heuristics to assess risk. An empirical study found no support for this position. Members of the public with the highest degrees of science literacy and technical reasoning capacity were not the most concerned about climate change. Rather, they were the ones among whom cultural polarization was greatest. This result suggests that public divisions over …

Improving Water Quality Antidegradation Policies, Robert L. Glicksman, Sandra B. Zellmer Jan 2012

Improving Water Quality Antidegradation Policies, Robert L. Glicksman, Sandra B. Zellmer

GW Law Faculty Publications & Other Works

The Clean Water Act’s principal goal is to “restore and maintain” the integrity of the nation’s surface water bodies. The Act’s adoption was spurred largely by the perception that unchecked pollution had caused the degradation of those waters, making them unsuitable for uses such as fishing and swimming. At the time Congress passed the statute, however, some lakes, rivers, and streams had water quality that was better than what was needed to support these uses. An important question was whether the statute would limit discharges with the potential to impair these high quality waters. EPA’s anti-degradation policy sought to ensure …

Microfluidic Separation Of Live And Dead Yeast Cells Using Reservoir-Based Dielectrophoresis, Saurin Patel, Daniel Showers, Pallavi Vedantam, Tzuen-Rong Tzeng, Shizhi Qian, Xiangchun Xuan Jan 2012

Microfluidic Separation Of Live And Dead Yeast Cells Using Reservoir-Based Dielectrophoresis, Saurin Patel, Daniel Showers, Pallavi Vedantam, Tzuen-Rong Tzeng, Shizhi Qian, Xiangchun Xuan

Mechanical & Aerospace Engineering Faculty Publications

Separating live and dead cells is critical to the diagnosis of early stage diseases and to the efficacy test of drug screening, etc. This work demonstrates a novel microfluidic approach to dielectrophoretic separation of yeast cells by viability. It exploits the cell dielectrophoresis that is induced by the inherent electric field gradient at the reservoir-microchannel junction to selectively trap dead yeast cells and continuously separate them from live ones right inside the reservoir. This approach is therefore termed reservoir-based dielectrophoresis (rDEP). It has unique advantages as compared to existing dielectrophoretic approaches such as the occupation of zero channel space and …

Factors Related To Sibling Involvement In Early Childhood Intervention, Julie Harp Rutland Jan 2012

Factors Related To Sibling Involvement In Early Childhood Intervention, Julie Harp Rutland

Theses and Dissertations--Early Childhood, Special Education, and Counselor Education

Professionals in early intervention have little information about the levels of sibling involvement in intervention, factors that contribute to sibling involvement, or how sibling involvement is related to families’ perceptions of self-efficacy. Few studies have investigated siblings in early intervention, and none have focused on relationships between sibling involvement in early intervention and parent self-efficacy. Using quantitative survey research this study investigated factors related to sibling involvement in early intervention strategies. Respondents completing the survey consisted of 129 parents who had a child enrolled in Michigan’s early intervention program, and at least one sibling in the home. Results indicated a …

Identifying Factors That Influence Terrorist Decisions And Target Selection, Barry C. Ezell, Joshua Behr, Andrew Collins Jan 2012

Identifying Factors That Influence Terrorist Decisions And Target Selection, Barry C. Ezell, Joshua Behr, Andrew Collins

VMASC Publications

Currently, the U.S. Department of Homeland Security (DHS) elicits probabilistic judgements from the intelligence community on actions terrorists may take to attack the continental U.S. For example, how likely is the adversary to choose agent 'x' over 'y' or target 'a' over target 'b'? Eliciting these types of judgements is difficult and time consuming. The National Academies and others have suggested that a better approach may be to elicit information on adversary's preferences, perceptions, and capabilities and use this information to calculate probabilities of interest to DHS. Some terrorist groups are thinking about using weapons of mass destruction (WMD), each …

The Diagnostic And Prognostic Value Of Salivary Scd44 Level Determination In Oral Malignant And Potentially Premalignant Lesions, Dalia Ghalwash, Fatheya Zahran, Khaled Gaaly, Olfat Shaker, Hossam Elfoll

Dentistry

A key factor in the lack of improvement in prognosis of oral squamous cell carcinoma (OSCC) lesions over the years is the fact that a significant proportion are not diagnosed or treated until they reach an advanced stage. A molecular marker for malignant transformation in innocent looking oral lesions and a monitor for the aggressiveness of malignant lesions might be of help. The present study included 40 subjects: 10 healthy control subjects, 10 patients with potentially premalignant oral lesions with dysplastic changes and 10 others without, in addition to 10 patients suffering from OSCC. Levels of soluble CD44 (sCD44) were …

The Influence Of Selenium Status On Immune Function And Antioxidant Status In The Horse, Mieke Brummer Jan 2012

The Influence Of Selenium Status On Immune Function And Antioxidant Status In The Horse, Mieke Brummer

Theses and Dissertations--Animal and Food Sciences

Selenium (Se) has received a lot of attention for its antioxidant and immune modulating properties. Yet, comparably few studies have focused on the horse. Therefore the objectives of this research were to evaluate the influences of Se status on immune function and antioxidant defense in horses. Twenty eight horses were allocated to one of 4 dietary Se treatments: low (LS), adequate (AS), high organic (SP) and high inorganic (SS). First, horses assigned to LS, SP and SS were depleted of Se and received a low Se diet (0.07 ppm Se) for 35 wk, while AS received an adequate Se diet …

Engaging And Enacting Writing In First-Year Composition: Re-Imagining Student Self-Efficacy In Writing, Mary L. Tripp Jan 2012

Engaging And Enacting Writing In First-Year Composition: Re-Imagining Student Self-Efficacy In Writing, Mary L. Tripp

Electronic Theses and Dissertations

According to educational theory, learning to write necessitates self-belief that one is capable of performing required tasks. This belief is called self-efficacy, a component of human agency. Students who enter First-Year Composition (FYC), are often unaware of the writing challenges that lie ahead, and many educational psychologists posit that self-efficacy beliefs are the most important factor in meeting these writing challenges. While socio-cognitive theory shapes views of self-efficacy in education literature, to date, measures of self-efficacy in writing have focused only on the individual cognitive beliefs as they influence writing performance outcomes. However, current research in writing studies as well …

Effects Of A Severe Cold Event On The Subtropical, Estuarine-Dependent Common Snook, Centropomus Undecimalis, Aaron J. Adams, Jessica E. Hill, Benjamin N. Kurth, Andrew B. Barbour Jan 2012

Effects Of A Severe Cold Event On The Subtropical, Estuarine-Dependent Common Snook, Centropomus Undecimalis, Aaron J. Adams, Jessica E. Hill, Benjamin N. Kurth, Andrew B. Barbour

Gulf and Caribbean Research

The effects of infrequent disturbance events on marine fishes are often difficult to determine, due largely to lack of sufficient pre- and post-disturbance event data. In January 2010, subtropical southwestern Florida (USA) experienced extreme cold for 13 days, which caused extensive mortality of many fish species. The effect of this severe cold event on common snook (Centropomus undecimalis), an economically important gamefish, was assessed using three years (2007-2009) of pre-event and one year (2010) of post-event data from a tag-recapture program conducted over 28 km of Gulf of Mexico barrier islands of Florida. All metrics pointed to a …

Early Growth Of Three Kingfish (Menticirrhus) Species Found In Coastal Waters Of The Northern Gulf Of Mexico, E. John Anderson, Bruce H. Comyns, Harriet Perry, Chet F. Rakocinski Jan 2012

Early Growth Of Three Kingfish (Menticirrhus) Species Found In Coastal Waters Of The Northern Gulf Of Mexico, E. John Anderson, Bruce H. Comyns, Harriet Perry, Chet F. Rakocinski

Gulf and Caribbean Research

Southern kingfish (Menticirrhus americanus), gulf kingfish (M. littoralis), and northern kingfish (M. saxatilis) are members of the drum family (Sciaenidae) that are widespread in coastal habitats of the western Atlantic, including in the Gulf of Mexico (GOM). Despite their economic and ecological importance, little is known about growth of young kingfish. Young kingfish were collected from four different Mississippi shoreline habitats in 2005 and 2006; two associated with barrier islands and two along the mainland. Barrier island habitats included surf zones on the south shore and grass beds on the north shore. Mainland habitats …

Flexible Feeding Strategies Of Juvenile Gray Triggerfish (Balistes Capriscus) And Planehead Filefish (Stephanolepis Hispidus) Within Sargassum Habitat, Sarah E. Ballard, Chet F. Rakocinski Jan 2012

Flexible Feeding Strategies Of Juvenile Gray Triggerfish (Balistes Capriscus) And Planehead Filefish (Stephanolepis Hispidus) Within Sargassum Habitat, Sarah E. Ballard, Chet F. Rakocinski

Gulf and Caribbean Research

Sargassum-associated juvenile gray triggerfish and planehead filefish exhibited flexible feeding strategies in terms of their use of epifauna or pelagic zooplankton. Four diet samples represented instances of co-occurrence and segregated occurrence. Co-occurring gray triggerfish had the most specialized diets consisting mainly of pelagic copepods and hyperiid amphipods. Conversely, segregated triggerfish as well as both co-occurring and segregated filefish had broader diets mainly consisting of Sargassum epifauna, such as bryozoans, portunid crabs, and hippolytid shrimp. Still, co-occurring planehead filefish also consumed somewhat more zooplankton than segregated planehead filefish. Ontogenetic diet transitions were not as distinct for gray triggerfish as for …

A New Baseline For Diadema Antillarum, Echinometra Viridis, E. Lucunter, And Eucidaris Tribuloides Populations Within The Cayos Cochinos Mpa, Honduras, Paul A.X. Bologna, Lucy Webb-Wilson, Patrick Connelly, James E. Saunders Jan 2012

A New Baseline For Diadema Antillarum, Echinometra Viridis, E. Lucunter, And Eucidaris Tribuloides Populations Within The Cayos Cochinos Mpa, Honduras, Paul A.X. Bologna, Lucy Webb-Wilson, Patrick Connelly, James E. Saunders

Gulf and Caribbean Research

We investigated the density of 4 urchin species from 5 shallow reefs in the Cayos Cochinos Marine Protected Area in Honduras. Individual species density varied among reefs with total urchin density ranging from 3.2–7.9 individuals/m2. Echinometra viridis (Agassiz, 1863) was the numerically dominant species (2.29/m2) followed by E. lucunter (Linnaeus, 1758) (1.76/m2) with Eucidaris tribuloides (Lamarck 1816) representing the fewest individuals (0.42/m2). Our results indicated that density of Diadema antillarum (Philippi, 1845) differed significantly among reefs (0.4-1.3/m2, mean = 0.63/m2), but are three times greater than data collected …
