Habitat Selection Of The Channel Darter, Percina (Cottogaster) Copelandi, A Surrogate For The Imperiled Pearl Darter, Percina Aurora, Pamela J. Schofield, Stephen T. Ross

Faculty Publications

Percina (Cottogaster) aurora is an imperiled species under consideration for listing by the U.S. Fish and Wildlife Service. To better understand habitat use of P. aurora, we studied a related and more abundant Cottogaster species, Percina copelandi, from the Ouachita River, Arkansas. We used a laboratory stream system to examine mesohabitat selection (pools versus riffles) and microhabitat selection (substratum particle size) of P. copelandi over three temperature regimes (summer, spring, and winter). Percina copelandi selected pool habitats over riffles and selected pools with coarse substrata (e.g., cobble) over fine substrata (e.g., gravel). In riffles, …

Cellular Proliferation, Death And Histology In Gambusia Affinis Livers After Exposure To 2-Aminofluorene And Benzidine, Susan J. Lentz

Dissertations

A fundamental need exists for aquatic animals in the biomonitoring of aquatic ecosystems for environmental carcinogens. G. affinis, a small fish species, is selected for this study due to its hardiness, non-migratory nature, geographic diversity and ability to develop tumors. Molecular tools for cellular proliferation and death are examined for use with G. affinis. Additionally, these tools are used to investigate the early carcinogenic effects of 2-aminofluorene and benzidine, both individually and combined, on G. affinis livers.

Antibodies to proliferating cell nuclear antigen (PCNA), p53, cleaved caspase-3 and cleaved poly(ADP-ribose) polymerase (PARP) were examined for use in G. …

Affective Expression And Behavior In Sex Offenders, Peter F. Rausch

Dissertations

This analytic variable study examined potential differences that exist among juvenile and adult sex offenders on the emotional expressiveness variables of alexithymia and affective orientation, and three behavior variables including self-defeating behavior, risk taking, and reckless behavior. In addition, the adult sex offenders' attachment style in current relationships was examined.

Research questions were tested by t -tests. The significance level for all analyses was set at the .05 level. An analysis of variance (ANOVA) was conducted to determine the primary attachment style of the adult sex offenders in current relationships.

Participants in this study were 47 juvenile sex offenders from …

Interspecies Encounters: An Ethnography Of A Veterinary Hospital, Dana Atwood-Harvey

Dissertations

There were three broad reasons for this research. The larger goal was to continue to advance the incorporation of 'other' animals and the rest of nature in general in sociological theory and research. The second was to suggest to those who have incorporated 'other' animals into their research, to include them as participants. The third was to redirect the focus of those who have incorporated 'other' animals as participants, to the impact that ideological structures and other social factors have on human-'other' animal encounters. Toward this end, I directed the focus of my study to examine human-'other' animal encounters ina …

Emotional Intelligence And Its Relationship With Sales Success, George C. Chipain

College of Education Theses and Dissertations

Emotional intelligence is a theoretical framework that organizes and integrates empirical research regarding emotions. Personal selling is the most effective marketing communication vehicle available to organizations because of its ability to adapt to specific customer needs. While two bodies of research have evolved regarding emotional intelligence theory and sales success predictors, little research has been carried out to link these two concepts together. This exploratory study tested a model of emotional intelligence and a measure of sales performance. The participants for the investigation were sales representatives in the personal home products industry. One hundred twenty-eight adult sales professionals completed a …

Life Cycle Of A Torrenticolous Hawaiian Chironomid (Telmatogeton Torrenticola): Stream Flow And Microhabitat Effects, M. Eric Benbow, Albert J. Burky, Carl M. Way

Biology Faculty Publications

In this study we documented the instar densities and life cycle of Telmatogeton torrenticola Terry (Chironomidae : Telmatogetoninae) from Kinihapai Stream, Maui, Hawaii. Greatest larval densities of this midge are found on substrates of high velocity, shallow flows of cascades, and splash zones of waterfalls, with lower densities in riffles. In the summer of 1994 we compared the effects of two microhabitats (termed optimal and suboptimal) on inter-instar density and relative abundance. In a second year (1995), we evaluated the effect of long-term reduced stream flow on these variables only in optimal microhabitats. A significant reduction in stream flow from …

Ground Water Resources And International Law In The Middle East Process, Yoram Eckstein, Gabriel Eckstein

Faculty Scholarship

Next to issues of land, water resources are the major bone of contention in the peace negotiations between Israel and the Palestinian Arabs. The objective of negotiations is de facto setting the clock back to the eve of the Israel War of Independence, when the Jews accepted the 1947 UN resolution of partition, while the Arabs rejected it. The Arabs now accept the principle of territorial partition, but at the same time, they demand re-apportioning of resources, mainly of water. The Palestinians contend that the facts created on the ground unilaterally by Israel during the last 50 years, namely the …

Bibliographies As An Extension Outreach Tool: An Old Method In A New Age, Janet Webster

Journal of Extension

Bibliographies, a librarian's basic tool, prove to be useful tools for Extension work. We all make lists of information--books, Extension bulletins, journal articles. Do we do it effectively? Defining the audience, determining the coverage, and creating timely access are a few of the challenges. Two Web-searchable bibliographies provide case studies of how this classic tool can address information needs.

Comparative Genome Organization Of Human, Murine, And Feline Mhc Class Ii Region, Naoya Yuhki, Thomas W. Beck, Robert M. Stephens, Yoko Nishigaki, Kymberly Newmann, Stephen J. O'Brien

Biology Faculty Articles

To study comparative molecular dynamics in the genesis of the major histocompatibility complex (MHC), we determined a complete nucleotide sequence spanning 758,291 bp of the domestic cat (Felis catus) extended and classical class II region. The feline class II MHC includes 44 genes (31 predicted to be expressed) which display DNA sequence homology and ordered gene synteny with human HLA and mouse H2, in extended class II and centromere proximal regions (DM to DO) of the classical class II region. However, remarkable genomic alterations including gene gain and loss plus size differentials of 250 kb are …

Factors Predicting Disrupted Versus Continuous Memory For Child Sexual Abuse, Tami Lorraine Young

Loma Linda University Electronic Theses, Dissertations & Projects

Information regarding the nature of disrupted memory for childhood sexual abuse (CSA) is limited. To increase understanding, repressive coping, dissociative tendencies, and characteristics of CSA were measured via survey in college students to determine if they predicted disrupted memory for CSA. Dissociative tendencies, but not repressive coping, predicted disrupted memory. Furthermore, repressive coping and dissociative tendencies were negatively correlated in those with disrupted memory for CSA. Characteristics of CSA loaded onto four factors: less physically intrusive CSA, significantly intrusive CSA, pornographic exploitative CSA and psychological impact of CSA. The psychological impact of CSA factor, greater number of years abused, and …

Comparison Of Receptor Efficacies On Vascular Smooth Muscle Contraction, Oommen K. George

Loma Linda University Electronic Theses, Dissertations & Projects

Vascular smooth muscle contraction involves multiple signal-transduction pathways, the interrelations of which are not completely understood. Our objectives in this project were to compare the effects of phenylephrine (alpha₁-adrenergic agonist, angiotensin II (AT₁ agonist), clonidine (alpha₂-adrenergic agonist) and moxondine (alpha₂- adrenergic /I₁-imidazoline agonist) on contraction in the rat-tail artery. Functionally, all these agonists cause contraction, but biochemically there are differences in how the result is achieved. We wanted to determine the role of protein kinase C (PKC) in the functional regulation between AT₁ and alpha₁-adrenergic receptor pathways. In …

A Novel Method To Detect Bacterial Restriction-Modification (R-M) Systems, Julie Kay Armantrout Kasarjian

Loma Linda University Electronic Theses, Dissertations & Projects

Analysis of recently sequenced microbial genomes has revealed many DNA sequences that code for previously unknown restriction endonucleases and their corresponding methyltransferases. These findings show that numerous restriction enzymes abundant in bacteria have yet to be discovered. Traditionally, restriction enzymes have been discovered by the classical restriction and modification (R-M) phenomena of bacteriophages (type I and III enzymes), or by direct enzyme assays (type II enzymes). To avoid the limitations of these traditional approaches, a quantitative R-M test based on plasmid transformation efficiency (Plasmid R-M Test) was established using DNA fragments derived from the E. coli bacteriophage lambda. This test …

Interaction Between Adrenergic And Nitric Oxide-Releasing Nerves In Cerebral Arteries, Emmanuel Ngu Mbaku

Loma Linda University Electronic Theses, Dissertations & Projects

Of all body tissues, the brain is the least tolerant of ischemia so much that interruption of cerebral blood flow by 5 sec can cause syncope, with irreversible tissue damage if the ischemia last a few minutes. In this respect, the body has an imperative duty of ensuring constant and adequate blood supply to the brain. It does so through a series of intrinsic and extrinsic control factors of which adrenergic and nitric oxide-releasing nerves are components. My research examined the interaction between these two nerve-types with emphasis on the mechanisms involved as well as on changes in their functions …

Effects Of Moral Sensitivity And Moral Climate On Moral Reasoning, Marita Louise Mahoney

Loma Linda University Electronic Theses, Dissertations & Projects

As healthcare professionals, psychology students and psychologists are expected to behave ethically and morally. It is assumed that moral and ethical reasoning in psychology students develops through exposure to ethical dilemmas within ethics classes and during clinical training experiences. Rest's Four Component Model of Moral Behavior, a neo-Kohlbergian approach to understanding moral development, posits an interaction of Moral Sensitivity, Moral Motivation, Moral Reasoning and Moral Character. Moral sensitivity, or awareness of a moral dilemma, is posited to cue the moral reasoning process, though little is known about how the training environment can facilitate or hamper such developments. Fifty".'two psychology-graduate students …

Effects Of Mtad On Some Physical Properties Of Enamel And Dentin, Tanya Kristina Machnick

Loma Linda University Electronic Theses, Dissertations & Projects

Recently, a Mixture of Tetracycline, an Acid, and a Detergent (MTAD) has been advocated to remove smear layer and disinfect canals. The purpose of this study was to evaluate the effect of MTAD the flexural strength and modulus of elasticity of dentin as well as its effect on the bond strength to enamel and dentin. In Part I, dentin bars were randomly assigned to eight groups treated either with various concentrations of NaOCl (5.25%, 2.65%, 1.31%, 0.66%), 17% EDTA, MTAD, saline, or according to a clinical protocol with 1.3% NaOCl and then 5 min of MTAD. …

Ultrasonic Removal Of Bacteria From Plated Cells, Cecilia Chi-Pei Kao

Loma Linda University Electronic Theses, Dissertations & Projects

Children often present with dental trauma to pediatric emergency departments and pediatric dental offices. There is a wide spectrum of types of dental trauma. Although research has been done concerning the treatment of avulsed teeth, the current recommendations in the published guidelines might still be improved for better long term prognoses. One may speculate that ultrasonification of an avulsed tooth prior to replantation may dislodge existing surface bacteria and improve the prognosis for the tooth. This was as an in vitro study to test this concept. Epithelial cells were grown in 6-well tissue culture plates. Standardized amounts of Staphylococcus aureus …

The Effect Of Ultrasonics On Fibroblast Cells, Sheila A. Harris

Loma Linda University Electronic Theses, Dissertations & Projects

The field of dentistry uses the debriding properties of ultrasonic vibration. It is unknown if this property is detrimental to the periodontal ligament (PDL) of an avulsed tooth. This information is important when a clinician is faced with a debris-covered avulsed tooth following a traumatic event. The purpose of this study was to determine the effect that ultrasonic vibration has on those PDL cells most numerous and most vital to a successful tooth replantation, namely, the fibroblasts.

Several fibroblast cell sources were exposed to varying ultrasonic times. These included a commercially available cell line of human foreskin fibroblast (HFF), a …

Exploring The Physician’S Processes: Diagnosing Autism, Gwennyth Li Sze Palafox

Loma Linda University Electronic Theses, Dissertations & Projects

Physicians are customarily the first point of contact for parents who are concerned about a child’s development. Thus, it is important for physicians to be current and educated about childhood disorders and subsequent treatment for those disorders. Recently, empirical evidence has led to the proposal of early indicators of autism supporting that autism may be diagnosed accurately in children less than three years old. Furthermore, formal screening and assessment parameters developed by medical organizations have been proposed in order to identify autism as early as possible (American Academy of Neurology, 2000). While the proposed parameters and empirical evidence support early …

Potential Mechanisms Explaining The Antitumor Effect Of Total-Body Irradiation, Glen Michael Miller

Loma Linda University Electronic Theses, Dissertations & Projects

While numerous reports have documented that radiation exposure increases the risk for malignancy and suppresses immune mechanisms, increasing evidence has suggested that low-dose total-body irradiation (TBI) may alter leukocyte composition and function leading to heightened immune responsiveness and long-term remission of certain cancers. Having observed that moderate-dose TBI produces an antitumor effect in the Lewis lung carcinoma (EEC) model, the major goal of this study was to determine whether changes in tumor growth could be correlated with radiation-induced alterations of immune system parameters. The governing hypothesis was that selective immune augmentation, i.e. upregulation of specific leukocyte subsets, is primarily responsible …

Long-Term Almond Supplementation: Effects On Diet, Eating Patterns, And Satiety In Free-Living Healthy Individuals, Karen Jaceldo-Siegl

Loma Linda University Electronic Theses, Dissertations & Projects

Because of the growing evidence of the cardio protective effect of nuts, examining the potential of nuts as a healthy food choice for the larger population should be considered. The purpose of this 12-month crossover study was to evaluate the impact on diet, eating patterns, and satiety of supplementing a self-selected diet (with little or no nuts) with ~52 g of almonds in free-living healthy males (43) and females (38) between the ages 25 and 70 years. The first six months constituted the control period where subjects followed their habitual diet (HD). During the intervention (second 6 months), subjects were …

“Growing Pains And Challenges”: Grandfamilies House Four-Year Follow-Up Evaluation, Alison S. Gottlieb, Nina M. Silverstein

Gerontology Institute Publications

During the past decade, there has been increased awareness of issues facing grandparent caregiver families on the part of policymakers and service providers. This awareness has prompted efforts to document the numbers of children being raised by grandparents, to identify challenges faced by grandparents raising grandchildren, and to provide services to meet the needs of these families. National estimates suggest that the numbers of grandparent caregiver families are increasing. Recent estimates suggest that 1.4 million (2%) of all children under 18 live in “skipped generation” families in the United States; similarly, 29,000 (nearly 2%) of all children in Massachusetts live …

Optimization Of Receptive Fields For Mlp Networks With Ensemble Encoding, Deena Osama Hassan

Archived Theses and Dissertations

Ensemble encoding is a biologically-motivated, distributed data representation scheme for MLP networks. Multiple overlapping receptive fields are used to enhance locality of representation. The number, form, and placement of receptive fields have a great impact on performance. This thesis presents four heuristics, two based on descriptive statistics, and two based on clustering, for optimizing receptive field configuration, and compares their performance on four benchmark data sets. The two statistical approaches are based on the mean and median properties of the data set. The two clustering methods are the c-means and fuzzy c-means clustering. The four data sets used are well-known …

Organizational Power And Politics: More Than Meets The Eye In Program Planning, Susan Shaver

Dissertations

Organizational power and politics influence corporate training in ways not often discussed. This study explores the effects of organizational power and politics on program planning and how planning, with its inherent power and politics (see Cervero & Wilson, 1994a), influences the daily practices of corporate trainers.

This study was informed by the literature of systems theory and constructivism. Von Bertalanffy’s (1968) general systems theory, in which the whole of a system is considered to be greater than the sum of its parts, Senge’s (1990) systems view that interrelationships within organizational structures, (not events), underlie complex situations, and Lincoln & Guba’s …
