The Effects Of Divorce On Children And Adolescents, Rachelle A. Haker

Graduate Research Papers

This research paper focuses on the effects of divorce on children and adolescents. Based on a review of literature, there are many short-term and long-term effects including emotional, behavioral, and physical issues. Children and adolescents vary in adjustment to divorce depending on multiple factors such as communication, conflict, and parental adjustment. The stages that children and adolescents of divorce go through depend on one's developmental stage and gender. Counselors can greatly influence how children and adolescents adjust to divorce.

Predictive Spatial Dynamics And Strategic Planning For Raccoon Rabies Emergence In Ohio, James E. Childs, David L. Smith, Colin A. Russell, Leslie A. Real

Zoonotics and Wildlife Disease: Publications

Rabies is an important public health concern in North America because of recent epidemics of a rabies virus variant associated with raccoons. The costs associated with surveillance, diagnostic testing, and post-exposure treatment of humans exposed to rabies have fostered coordinated efforts to control rabies spread by distributing an oral rabies vaccine to wild raccoons. Authorities have tried to contain westward expansion of the epidemic front of raccoonassociated rabies via a vaccine corridor established in counties of eastern Ohio, western Pennsylvania, and West Virginia. Although sporadic cases of rabies have been identified in Ohio since oral rabies vaccine distribution in 1998, …

Experimental Transmission Of Chronic Wasting Disease Agent From Mule Deer To Cattle By The Intracerebral Route, Amir N. Hamir, Robert A. Kunkle, Randall C. Cutlip, Janice M. Miller, Katherine I. O'Rourke, Elizabeth S. Williams, Michael W. Miller, Mick J. Stack, Melanie J. Chaplin, Jügen A. Richt

Zoonotics and Wildlife Disease: Publications

This communication reports final observations on experimental transmission of chronic wasting disease (CWD) from mule deer to cattle by the intracerebral route. Thirteen calves were inoculated intracerebrally with brain suspension from mule deer naturally affected with CWD. Three other calves were kept as uninoculated controls. The experiment was terminated 6 years after inoculation. During that time, abnormal prion protein (PrP^res) was demonstrated in the central nervous system (CNS) of 5 cattle by both immunohistochemistry and Western blot. However, microscopic lesions suggestive of spongiform encephalopathy (SE) in the brains of these PrP^res-positive animals were subtle in 3 …

Coordinated Contingency Planning In The Face Of Uncertainty In The National Aviation System, Philip J. Smith, Amy Spencer, Charlie Billings

International Symposium on Aviation Psychology - 2005

One of the major challenges for strategic planning in aviation concerns uncertainty about weather and traffic constraints, as traffic managers often have to disseminate reroute advisories 2 hours before an expected constraint impacts an airport, and dispatchers file flight plans 60-75 minutes before a flight’s departure. When the predictions used to for these plans are wrong, significant inefficiencies (unused airspace and runway capacity from a traffic manager’s perspective and delayed flights from a dispatcher’s perspective) often result. To make operations more adaptive, new procedures have been developed. These procedures involve using predefined Coded Departure Routes, and are now being extended …

A Simulation Evaluation Of A Human-Centered Approach To Flight Deck Procedures And Automation For En Route Free Maneuvering, Walter W. Johnson, Vernol Battiste, Stacie Granada, Nancy Johnson, Arik Quang Dao, Dominic Wong, Anthony Tang

International Symposium on Aviation Psychology - 2005

A joint simulation was conducted by NASA Ames and Langley Research Centers. This paper presents flight deck performance and subjective data collected at the NASA Ames Research Center. During the simulation of en route free maneuvering, the presence and mixture of managed and autonomous aircraft was manipulated, as was the number of autonomous aircraft.. These manipulations allowed for an examination of the viability of both conducting mixed AFR-IFR operations, and of substantially increasing en route traffic through insertion of AFR aircraft. The Ames airside performance and pilot comment data support the safety and feasibility of the concept, with double en …

Optimising Physiotherapy Care For Acute Low Back Pain – Identifying Non-Responders To Treatment, James H. Mcauley, Benedict M. Wand, C Bird, Lorraine H. De Souza

Health Sciences Conference Papers

Recent evidence suggests that positive effects of physiotherapy for acute low back pain patients can be achieved if treatment is delivered early enough. However it is clear that not all patients treated with physiotherapy are likely to report equally positive outcomes from their treatment. The identification of clinical characteristics of those patients who do less well will help refine models of care for acute low back pain.

Aim: To identify non-responders to early active physiotherapy.

Method: A secondary analysis was conducted on the data from a recently published randomised controlled trial of early physiotherapy for acute low back pain. All …

A Developed Country Approach To Eliminating Blinding Trachoma, Donna B. Mak

Medical Conference Papers

In Australia trachoma is endemic, only in pockets among aboriginal people. The TF prevalence in school-age children in 2002−2003 ranged from 0−27% (district) and 0−60% (community).⁴ Trichiasis in indigenous adults in highly disease-endemic communities over the age of 40 years is approximately 10%. There are limited data on face-washing, but a survey of three schools in 2004 gave rates of 55%. The rate of latrine use and access to water is almost universal (96%).

Language Production: A Complex Dynamic System With A Chronometric Footprint, Kim Kirsner, John Dunn, Kathryn Hird

Medical Conference Papers

In this paper we outline a new approach to the study of language production. Central to this approach is the assumption that communication takes place in a dynamic environment in which cognitive resources are deployed to achieve ‘Right-Time’ as distinct from ‘Fast-as-Possible’ solutions. This is based on the assumption that language production includes a single, integrated, interactive process that recruits and coordinates information from a variety of internal, external and interactive sources to build each speech segment. The output of this process is reflected in the longer of the two log-normal pause duration distributions observed in spontaneous speech (Kirsner, Dunn, …

Aphasia Classification: The Relationship Between Objective Measures Of Spontaneous Speaking Samples And Naive Listener Judgments Of Similarity And Fluency, Kathryn Hird, Joanne Silvestri, John Dunn, Kim Kirsner

Medical Conference Papers

For an objective measure to be useful in a clinical setting it must correlate with perceptions of the speaker and what is considered “normal” (Kreiman, Gerratt, Kempster, Erman, & Berke, 1993). Perceptions of the functional communicative abilities of people with aphasia do not correlate well with changes on decontextualised linguistic measures (Wertz, 1999). In addition, the current practice of reliance on specific perceptual ratings of fluency of speech has been shown to be unreliable (Gordon, 1998; Kent, 1996,). Using a multidimensional scaling technique Kreiman, Gerratt & Precoda (1990) found that naïve and expert listeners attended to different aspects of voice …

Play Therapy, Melissa A. Hardman

Graduate Research Papers

Play therapy techniques are valuable tools for a variety of professionals who work with children. One need not be a registered play therapist to implement play techniques when working with child clients. There are many types of clients that would benefit from play therapy. There are several different theoretical approaches, but the researcher chose to focus on Adlerian Play Therapy, Client-Centered Play Therapy, Cognitive-Behavioral Play Therapy, and Psychodynamic Play Therapy. The paper considers the best location to implement play techniques, by urging the counselor to be aware of the setting's location within the building, ease of cleaning, available space, and …

Cost - Minimization Analysis Of Treprostinil Vs. Epoprostenol As An Alternate To Oral Therapy: Non - Responders For The Treatment Of Pulmonary Arterial Hypertension, Lutchmie Narine, L. Hague, J. Walker, C. Vicente

Public Health, Food Studies, and Nutrition

Idiopathic pulmonary arterial hypertension (IPAH) is associated with substantial morbidity and mortality. Treprostinil was compared to epoprostenol for the economic impact of treating IPAH patients who failed or were not candidates for bosentan. METHODS: The model was a cost-minimization analysis, assuming clinical equivalence was achieved by proper dosing of both drugs, in terms of survival and surrogate measures. Two theoretical cohorts of 270 patients were treated with subcutaneous treprostinil and intravenous epoprostenol, and were evaluated over 3 years using a spreadsheet model. Annual survival rates were estimated for the cohorts so that at endpoint 114 (42%) patients survived in both …

Genome Size And Organization In The Blacklegged Tick, Ixodes Scapularis And The Southern Cattle Tick, Boophilus Microplus, A. J. Ullmann, C. M. R. Lima, F. D. Guerrero, J. Piesman, W. C. Black Iv

United States Public Health Resources

Genome sizes and the organization of repetitive DNA were determined in the hard ticks Ixodes scapularis and Boophilus microplus using reassociation kinetics. The I. scapularis genome contains ~ 2.15 pg (2.1 × 10 ³ Mbp) of DNA and consists of no foldback (FB), 27% highly repetitive (HR), 39% moderately repetitive (MR), and 34% unique DNA. The B. microplus genome contains 7.5 pg (7.1 × 10 ³ Mbp) DNA, and consists of 0.82% FB, 31% HR, 38% MR, and 30% unique DNA. In both species, repetitive sequences occur in a mixture of long and short period interspersion but most (65–80%) of …

Evolutionary Genetics Of A New Pathogenic Escherichia Species: Escherichia Albertii And Related Shigella Boydii Strains, Katie E. Hyma, David W. Lacher, Adam M. Nelson, Alyssa C. Bumbaugh, J. Michael Janda, Nancy A. Strockbine, Vincent B. Young, Thomas S. Whittam

United States Public Health Resources

A bacterium originally described as Hafnia alvei induces diarrhea in rabbits and causes epithelial damage similar to the attachment and effacement associated with enteropathogenic Escherichia coli. Subsequent studies identified similar H. alvei-like strains that are positive for an intimin gene (eae) probe and, based on DNA relatedness, are classified as a distinct Escherichia species, Escherichia albertii. We determined sequences for multiple housekeeping genes in five E. albertii strains and compared these sequences to those of strains representing the major groups of pathogenic E. coli and Shigella. A comparison of 2,484 codon positions in 14 …

Non-O157 Shiga Toxin–Producing Escherichia Coli Infections In The United States, 1983–2002, John T. Brooks, Evangeline G. Sowers, Joy G. Wells, Katherine D. Greene Greene, Patricia M. Griffin, Robert M. Hoekstra, Nancy A. Strockbine

United States Public Health Resources

Background. Shiga toxin–producing Escherichia coli (STEC) O157:H7 is a well-recognized cause of bloody diarrhea and hemolytic-uremic syndrome (HUS). Non-O157 STEC contribute to this burden of illness but have been underrecognized as a result of diagnostic limitations and inadequate surveillance.

Methods. Between 1983 and 2002, 43 state public health laboratories submitted 940 human non-O157 STEC isolates from persons with sporadic illnesses to the Centers for Diseases Control and Prevention reference laboratory for confirmation and serotyping.

Results. The most common serogroups were O26 (22%), O111 (16%), O103 (12%), O121 (8%), O45 (7%), and O145 (5%). Non-O157 STEC infections were …

Identification And Characterization Of Shigella Boydii 20 Serovar Nov., A New And Emerging Shigella Serotype, David L. Woodward, Clifford G. Clark, Richard A. Caldeira, Rafiq Ahmed, Geoff Soule, Louis Bryden, Helen Tabor, Pasquale Melito, Roger Foster, Julie Walsh, Lai-King Ng, Georgia B. Malcolm, Nancy Strockbine, Frank G. Rodgers

United States Public Health Resources

Analysis of 163 putative Shigella isolates from Canada and the USA showed biochemical reactions consistent with Shigella species, although none of the isolates reacted with antiserum raised against any of the well-established or provisional Shigella serotypes. All these isolates, provisionally designated serotype SH108, were positive for the ipaH gene and the invasion-associated locus. All fermented mannitol, were serologically indistinguishable from each other and showed no reaction in antisera prepared against Escherichia coli serotypes O1 to O181. PCR-RFLP analysis of the genes involved in O-antigen synthesis revealed a common pattern among these isolates that was distinct from recognized Shigella serotypes and …

Evaluating Current Policy For Detecting Mosaicism In Amniotic Fluid Cultures: Implications For Current Cell Counting Practices, Samuel P. Caudill, Daniel L. Van Dyke, Andrew T. L. Chen, John A. Reidy, Paul S. Ing, Stuart Schwartz, Gail H. Vance

United States Public Health Resources

Chromosomal mosaicism is one of the most vexing problems for clinical cytogenetic laboratories and personnel time used for analysis at the microscope is one of the principle costs in cytogenetic laboratories. We use data collected from 26 cytogenetic laboratories to evaluate whether the American College of Medical Genetics guidelines for minimum number of cells to count to exclude mosaicism in amniotic fluid specimens is appropriate. An accurate estimate of the number of mosaics that are missed by current cell counting practices is an important step in this process. Thus, we present a new method for estimating the number of mosaics …

Molecular Cloning And Characterization Of A Porcine Ul16 Binding Protein (Ulbp)-Like Cdna, Carmen N. Garcia-Borges, Bounleut Phanavanh, Sarika Saraswati, Richard A. Dennis, Mark D. Crew

United States Public Health Resources

UL16 binding proteins (ULBPs) are ligands for the NK cell activating receptor NKG2D. A cDNA encoding a porcine ULBP-like protein (PULBP) was cloned and the predicted amino acid sequence exhibited 35–52% identity to human ULBPs. Southern blot analysis suggested that there is only one ULBP-like gene in the pig genome. Transcripts of PULBP and another potential NKG2D ligand, MIC2, were detected by RT-PCR in a wide range of tissues. Recombinant PULBP-Fc and human ULBP2-Fc fusion proteins were made and used to examine PULBP binding to porcine PBMCs and a human NK cell line (NKL cells). PULBP-Fc bound to a subpopulation …

Phylogenetic Analysis Of North American West Nile Virus Isolates, 2001–2004: Evidence For The Emergence Of A Dominant Genotype, C. Todd Davis, Gregory D. Ebel, Robert S. Lanciotti, Aaron C. Brault, Hilda Guzman, Marina Siirin, Amy Lambert, Ray E. Parsons, David W.C. Beasley, Robert J. Novak, Darwin Elizondo-Quiroga, Emily N. Green, David S. Young, Lillian M. Stark, Michael A. Drebot, Harvey Artsob, Robert B. Tesh, Laura D. Kramer, Alan D.T. Barrett

United States Public Health Resources

The distribution of West Nile virus has expanded in the past 6 years to include the 48 contiguous United States and seven Canadian provinces, as well as Mexico, the Caribbean islands, and Colombia. The suggestion of the emergence of a dominant genetic variant has led to an intensive analysis of isolates made across North America. We have sequenced the premembrane and envelope genes of 74 isolates and the complete genomes of 25 isolates in order to determine if a dominant genotype has arisen and to better understand how the virus has evolved as its distribution has expanded. Phylogenetic analyses revealed …

Agricultural Pesticide Use And Risk Of Glioma In Nebraska, United States, W. J. Lee, J. S. Colt, E. F. Heineman, R. Mccomb, D. D. Weisenburger, W. Lijinsky, M. H. Ward

United States Public Health Resources

Background: To evaluate the risk of the adult glioma associated with farming and agricultural pesticide use, the authors conducted a population based case control study in eastern Nebraska.
Methods: Telephone interviews were conducted with men and women diagnosed with gliomas (n = 251) between 1988 and 1993 and controls (n = 498) randomly selected from the same geographical area. Unconditional logistic regression was used to calculate adjusted odds ratios (ORs) for farming and for use of individual and chemical classes of insecticides and herbicides, including pesticides classified as nitrosatable (able to form N-nitroso compounds upon reaction with nitrite). Non-farmers were …

Role Of Elevated S-Adenosylhomocysteine In Rat Hepatocyte Apoptosis: Protection By Betaine, Kusum K. Kharbanda, David D. Rogers Ii, Mark E. Mailliard, Gerri L. Siford, Anthony J. Barak, Harriet C. Beckenhauer, Michael F. Sorrell, Dean J. Tuma

United States Public Health Resources

Previous studies from our laboratory have shown that ethanol consumption results in an increase in hepatocellular S-adenosylhomocysteine levels. Because S-adenosylhomocysteine is a potent inhibitor of methylation reactions, we propose that increased intracellular S-adenosylhomocysteine levels could be a major contributor to ethanol-induced pathologies. To test this hypothesis, hepatocytes isolated from rat livers were grown on collagen-coated plates in Williams’ medium E containing 5% FCS and exposed to varying concentrations of adenosine in order to increase intracellular S-adenosylhomocysteine levels. We observed increases in caspase-3 activity following exposure to adenosine. This increase in caspase activity correlated with increases in intracellular S-adenosylhomocysteine levels and …

Measurements Of Constraint Of Total Knee Replacement, H. Haider, P.S. Walker

United States Public Health Resources

Measurement of the constraint of total knee components in a test machine provides an objective method of describing the laxity and stability characteristics of the implant itself, independent of the knee joint into which it would be implanted. A special fixture was designed and fitted to a Bionix multi-channel loading machine. The test consisted of applying a compressive load, applying a cyclic AP force or internal-external torque, and measuring all of the displacements and rotations. Three different commonly-used TKR’s showed widely different constraint characteristics. In the cyclic AP test, along with the cyclic AP displacement, displacements and rotations occurred in …
