The Standardized Fish Bioassay Procedure For Detecting And Culturing Actively Toxic Pfiesteria, Used By Two Reference Laboratories For Atlantic And Gulf Coast States, Joann M. Burkholder, Harold G. Marshall, David W. Seaborn, Nora J. Deamer-Melia

Biological Sciences Faculty Publications

In the absence of purified standards of toxins from Pfiesteria species, appropriately conducted fish bioassays are the "gold standard" that must be used to detect toxic strains of Pfiesteria slop. from natural estuarine water or sediment samples and to culture actively toxic Pfiesteria. In this article, we describe the standardized steps of our fish bioassay as an abbreviated term for a procedure that includes two sets of trials with fish, following the Henle-Koch postulates modified for toxic rather than infectious agents. This procedure was developed in 1991, and has been refined over more than 12 years of experience in …

The Distribution Of Airborne Coal Dust In Soil Profiles Of Norfolk, Va And Its Implication For Arsenic Loading To These Soils, William Joseph Bounds

OES Theses and Dissertations

Norfolk, Virginia is home to the Northern Hemisphere's largest coal terminal the Lamberts Point Docks. The coal loading process of this terminal creates large amounts of coal dust, which subsequently is distributed throughout the local region by atmospheric transport and deposition. While the coal dust itself poses only minor health hazards, certain trace elements within the coal, particularly arsenic, may pose environmental as well as significant health hazards. Within coal, arsenic occurs primarily in the mineral pyrite. As pyrite in the coal dust is subsequently oxidized via exposure to the atmosphere and/or meteoric water, arsenic may be released to the …

Application And Interpretation Of Simple Odds Ratios In Physical Therapy-Related Research, Pamela Levangie

All PTHMS Faculty Publications

Over the past several decades, physical therapists have demonstrated an increasing responsiveness to the profession's obligation to generate objective evidence for examination and intervention strategies employed in physical therapy practice. This trend is evident, not only in the increasing number of journals that are publishing physical therapy research, but in the growing sophistication of research design and analytic options used by investigators. At the same time, physical therapists are held increasingly accountable for adopting an evidence-based approach to practice. The result for many of us is a growing concern about our ability to interpret study findings. The ability to independently …

Nonparametric Techniques To Extract Fuzzy Rules For Breast Cancer Diagnosis Problem, Manish Sarkar, Tze-Yun Leong

Research Collection School Of Computing and Information Systems

This paper addresses breast cancer diagnosis problem as a pattern classification problem. Specifically, the problem is studied using Wisconsin-Madison breast cancer data set. Fuzzy rules are generated from the input-output relationship so that the diagnosis becomes easier and transparent for both patients and physicians. For each class, at least one training pattern is chosen as the prototype, provided (a) the maximum membership of the training pattern is in the given class, and (b) among all the training patterns, the neighborhood of this training pattern has the least fuzzy-rough uncertainty in the given class. Using the fuzzy-rough uncertainty, a cluster is …

Ethics As Therapy: Philosophical Counseling And Psychological Health, Mike W. Martin

Philosophy Faculty Articles and Research

From the inception of philosophical counseling an attempt was made to distinguish it from (psychological) therapy by insisting that therapy could not be more misleading. It is true that philosophical counselors should not pretend to be able to heal major mental illness; nevertheless they do contribute to positive health—health understood as something more than the absence of mental disease. This thesis is developed by critiquing Lou Marinoff’s book, Plato not Prozac!, but also by ranging more widely in the literature on philosophical counseling. I also interpret philosophical counseling as a form of philosophical ethics.

Minimum Mean Square Error Spectral Peak Envelope Estimation For Automatic Vowel Classification, Jaishree Venugopal

Electrical & Computer Engineering Theses & Dissertations

Spectral feature computations continue to be a very difficult problem for accurate machine recognition of speech. In this work, which focuses on vowels, a new spectral peak envelope method for vowel classification is developed, based on a missing frequency components model of speech recognition. According to the missing frequency components model, vowel recognition depends only on the spectral (harmonic) peaks. Smoothing and interpolation of the spectra, performed in the standard cepstral analysis method commonly used in automatic speech recognition, actually loses valuable information and results in reduced recognition accuracy. The new method for feature extraction presented in this thesis is …

Advancing Scientific Discourse In The Controversy Surrounding The Comprehensive System For The Rorschach: A Rejoinder To Meyer (2000), James M. Wood, M. Teresa Nezworski, William J. Stejskal, Sena Garven

Department of Psychology: Faculty Publications

A recent commentary by Meyer (2000) in the Journal of Personality Assessment alleged that Rorschach critic Wood and his colleagues had intentionally published information that they knew to be in error. To substantiate this contention, Meyer’s commentary published information that was part of the peer review process at another journal. In this rejoinder, we present factual information that shows we have consistently acted in good faith. This rejoinder suggests that the scientific debate regarding the Comprehensive System for the Rorschach is unlikely to be advanced by speculating about the intentions of Rorschach critics, or by publishing information from the peer …

The study assessed the reliability of the Spanish and English versions of the Schedule of Sexist Events General Form (SSE-G). The extent to which Spanish and English-speaking men and women differed in their responses on the SSE-G was investigated, as was the degree to which men and women differed in their report of psychiatric symptoms. Further, the extent to which the SSE-G predicted psychiatric symptomology for Spanish and English-speaking men and women was assessed, as was the extent to which sexism (i.e., gender-specific stress) accounted for additional variance in symptoms, above and beyond that accounted for by acculturation, language, and …

Quality Improvement Tools In Disease Management, Lisa E. Paddock, Amy L. Phillips, Peter Chodoff

College of Population Health Faculty Papers

Disease management programs require constant monitoring to assure quality and address problems efficiently. To initiate continuous quality improvement in a disease management program, there are several methods available to identify potential problems within the program that may be affecting quality. Some common quality improvement instruments include the Plan-Do-Check-Act model, check sheets, and so forth. Whatever model is used, Statistical Process Control using flow charts, histograms, Pareto diagrams, scatter diagrams, control charts, and cause-and-effect diagrams provides a better understanding about how the organization's processes are functioning. These tools facilitate problem recognition and allow an organization to meet established standards of quality …

Studies On The Formation Of Dna-Cationic Lipid Composite Films And Dna Hybridization In The Composites, Murali Sastry, Vidya Ramakrishnan, Mrunalini Pattarkine, Krishna N. Ganesh

Faculty Works

The formation of composite films of double-stranded DNA and cationic lipid molecules (octadecylamine, ODA) and the hybridization of complementary single-stranded DNA molecules in such composite films are demonstrated. The immobilization of DNA is accomplished by simple immersion of a thermally evaporated ODA film in the DNA solution at close to physiological pH. The entrapment of the DNA molecules in the cationic lipid film is dominated by attractive electrostatic interaction between the negatively charged phosphate backbone of the DNA molecules and the protonated amine molecules in the thermally evaporated film and has been quantified using quartz crystal microgravimetry (QCM). Fluorescence studies …

Multidisciplinarity And Cognitive Science, Barbara Von Eckardt

Department of Psychology: Faculty Publications

The aim of Schunn, Crowley and Okada’s (1998) study is to address the question of whether the current state of cognitive science, as represented by Cognitive Science and the Cognitive Science Society, “reflects the multidisciplinary ideals of its foundation.” To properly interpret and respond to their results, we need to ask a prior question: What is cognitive science’s multidisciplinary ideal? There are at least two conceptions—a “localist” conception, which seems to be implicit in Schunn, Crowley and Okada’s discussion, and a “holist” conception. I argue that while both have been endorsed by some cognitive scientists, there are reasons for preferring …

Magnetic Resonance Imaging And Three-Dimensional Reconstructions Of The Brain Of A Fetal Common Dolphin, Delphinus Delphis, Lori Marino, Timothy L. Murphy, Lyad Gozal, John I. Johnson

Series of scans were obtained in coronal, sagittal and horizontal planes. A digital three-dimensional reconstruction of the whole brain was prepared from the coronal series of scans. Sectional areas and three-dimensional volumes were obtained of the cerebral hemispheres and of the brainstemplus-cerebellum. Neuroanatomical features identified in the scans include the major sulci of …

Between- Or Within-Culture Variation? Culture Group As A Moderator Of The Relations Between Individual Differences And Resource Allocation Preferences, Gustavo Carlo, Scott C. Roesch, George P. Knight, Silvia H. Koller

Department of Psychology: Faculty Publications

Recent theoretical discussion of the influence of between- and within-culture factors on social behaviors suggests that both approaches may be useful. The present study was designed to investigate the joint influence of sociocultural (between-group) and individual (within-group) factors on resource allocation preferences. Brazilian (n = 166) and European-American (n = 99) children with ages ranging from 37 to 140 months were administered a resource allocation task, which consisted of distributing rewards to themselves or to an acquaintance. As expected, individualistic resource allocation preferences decreased with age, whereas competitive and cooperative resource allocation preferences increased with age. Culture group, the task-specific …

Hand Intensive Leisure Activities And Repetitive Motion Injuries Of The Distal Upper Extremities, Marilyn Colvin Wright

Loma Linda University Electronic Theses, Dissertations & Projects

Background. The work-relatedness of repetitive motion injuries to the distal upper extremities (RMI-DUEs) has been well documented; however, human occupation extends beyond the job to include self-care and leisure activities. The effects of hand intensive leisure activities (HILAs) such as home computer use and needlework on RMI-DUEs have not been explored. These HILAs require hand usage similar to known work-related risk factors. Additionally, sedentary leisure contributes to obesity thereby increasing the disease burden of women. Health beliefs regarding leisure and fitness among women employed in hand intensive sedentary jobs have not been explored.

Purpose. The purpose of this study was …

A Comparison Of Phytoplankton Communities In Lake Prince And The Western Branch Reservoir, Suffolk, Virginia, Cara Marie Muscio

Biological Sciences Theses & Dissertations

Lake Prince and the Western Branch Reservoir are two eutrophic bodies of water located in Suffolk, Virginia. Lake Prince and its two small tributaries join the Western branch via a constructed spillway. This lake system is a source of water for the surrounding municipalities, and a recreational area for community citizens. In the past, these bodies of water had repeated incidents of low oxygen and nuisance algal blooms, particularly cyanobacteria species. As a result aerators have been installed in the main body of both Lake Prince and the Western Branch Reservoir. In addition, a pipeline has been installed from North …
