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 …

Essential Elements Of An Implementation Process For Grant-Funded Projects/Programs In Nonprofit Organizations, Margaret M. Bernhard

Dissertations

Grant seeking is a source of funding for many nonprofit organizations. If a proposal is funded, the organization must contend with the responsibility of project implementation and the expectations of successful project outcomes. A project implementation process with strategic and tactical steps that clearly define the path that leads to positive grant outcomes would assist the grant administrator. Using the Delphi Method as a methodological tool for facilitating dialog among anonymous experts, 12 foundation program officers identified, ranked, and rated the essential elements and barriers of grant implementation. The process revealed 13 essential elements of implementation and 11 barriers to …

Treatment Of Specific Animal Phobias And The Relationship Of An Opiate Antagonist To Outcome, Andrea T. Kozak

Dissertations

Previous research with non-humans, and humans to a lesser degree, suggest the endogenous opiate system is at work to assist an organism in times of pain or stress. One-session exposure treatment is an effective treatment for specific animal phobia and entails modest degrees of stress during implementation. At the present time, the mechanisms at work that facilitate the success of this intervention have been incompletely investigated. The focus of the present study was to determine whether the endogenous opiate system is activated during the treatment of persons with specific animal phobias. In a double-blind investigation, 15 individuals with specific animal …

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. …

This dissertation demonstrated the use of behavioral systems analysis tools in the development of a useful service in a non-profit association. The purpose of this study was threefold: (1) to design a placement system that would add value to the field of behavior analysis by placing behavior analysts in appropriate jobs, internships, and graduate programs; (2) to develop a data collection infrastructure that would assist the Association for Behavior Analysis (ABA) in the assessment of the trends related to the human resources of the field; and (3) to advance the knowledge and methodology of behavioral systems analysis.

Six objectives were …

A Behavior Systems Analysis Approach To Designing A Hlgh-Impact Knowledge Management System, Jacalyn S. Smeltzer

Dissertations

Behavior systems analysis is an approach to designing and managing systems that incorporates the human-performance-technology model of systems analysis and considers the basic principles of behavior when analyzing causes of performance deficiencies and in selecting interventions to address those deficiencies. Behavior systems analysis focuses on three major conditions that influence behavior: (1) the motivation of the individual, (2) the immediate environmental cues, and (3) the consequences of behavior (Malott & Garcia, 1987; Suarez, 2001). The present study used behavior systems analysis to design a knowledge management system (independent variable) for a small business, a consulting firm in the employer-provided training …

The Enigma Of The Great Cities: Body And State In Amazonia, Michael J. Heckenberger

Tipití: Journal of the Society for the Anthropology of Lowland South America

This paper discusses issues of political power in Amazonia, particularly with regard to traditional definitions of the State, in general, and the body or person in Amazonia. Using the historical ethnography of the Upper Xingu region of southern Amazonia as a point of departure, issues of inequality, hierarchy, and social complexity are briefly discussed. Specifically, it is suggested that Xinguano cultural patterns, considered over the long term (circa 800 C.E.–present), show evidence of social hierarchy and regional organization considered characteristic of so-called complex societies elsewhere. As is true in many ancient states and chiefdoms, power is based on strategic control …

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 …

Partnerships For Natural Resource Education: Differing Program Needs And Perspectives Of Extension Agents And State Agency Staff, Martha C. Monroe, Susan K. Jacobson, Alison Bowers

Journal of Extension

An evaluative survey of 45 Extension agents and 59 state forestry agency staff in Florida 1 year after a joint in-service training provides insight into the program needs for both groups as they develop public education programs on wildland fire. Results analyzed three primary barriers to program implementation: educational, logistical, and attitudinal, providing insight into the needs for both groups as they develop public education programs. Providing a toolkit of materials and resources reduces logistical and educational barriers and assists agents with program delivery in a new topic area. Supervisor support may be key to reducing additional barriers that agents …

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.

Agricultural Science Fairs: Are Students Truly Learning From This Activity?, Ct Boleman, F Burrell Jr

Journal of Extension

Agriculture Science Fairs are designed to teach youth how agriculture is a part of their lives. A study measured the knowledge change of youth participating in an agricultural science fair in Texas. A pre-test/post-test was administered to 480 participants that revealed an increase in correct responses for nine out of 10 questions. Two scale statements revealed significant increases (p < 0.05) related to thoughts on how agriculture affects everyday life. Teachers were administered an ex-post facto instrument, and results indicated that the activity was a positive learning experience but that specific curriculum should be designed to support the activity.

Review Of Micromedium Digital Trainer Professional(R) As A Tool For Developing Teaching And Extension Training Programs, Y Martin Lo, Lisa N. Sadar

Journal of Extension

The authors have been using Digital Trainer Professional® software for more than 4 years and found it to be effective in teaching classes and Extension training programs. The merit of the program is that, instead of reading a training manual or paper book, trainees interact with an e-book on their computer. E-books can track the reader's knowledge and evaluate responses to questions to measure their progress and performance, and gauge the effectiveness of the training.

An Inquiry Into Portland's Canine Quandary: Recommendations For A Citywide Off-Leash Program, Jeff Gimour, Heather Gundersen, Doug Miller, Emily Moore, Amy Rose

Master of Urban and Regional Planning Workshop Projects

The City of Portland currently faces a difficult challenge. As the population continues to grow, greater pressure is placed upon the limited amount of public open space available for recreation. As stated in the Portland Parks & Recreation (PP&R) 2020 Vision Plan, "Demographic, recreational, and funding trends suggest that both current shortages and future needs will intensify and produce inequities in our cherished park system" (PP&R, 2001).

Today, Portland's already strained park system struggles to accommodate demands for the myriad of recreational activities. Competition among park users - joggers, tennis players, picnickers, dog owners, bicyclists, and others - for limited …

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 …

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 …

Distraction Osteogenesis In Edentulous Alveolar Bone With Rhbmp-2 Enhancement, Liviu F. Eftimie

Loma Linda University Electronic Theses, Dissertations & Projects

Distraction osteogenesis, a unique system of affecting rapid bone healing in fractures, realigning malformed bones, and lengthening congenitally short and traumatically shortened bones has become an increasingly utilized technique for the maxillofacial region. The use of distraction osteogenesis has been described for increasing the height of edentulous mandibular alveolar ridges while concurrently forming new bone within the ridge to allow for adequate reconstruction. A standard protocol for performing distraction osteogenesis in the maxillofacial region has been well documented in the literature. Standard distraction osteogenesis requires an initial surgery to place the distraction osteogenesis device and mobilize the segment to be …

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 …

Lives, Life-Years, And Willingness To Pay, Cass R. Sunstein

Coase-Sandor Institute for Law & Economics Research Paper Series

In protecting safety, health, and the environment, government has increasingly relied on cost-benefit analysis. In undertaking cost-benefit analysis, the government has monetized risks of death through the idea of "value of a statistical life" (VSL), currently assessed at about $6.1 million. Many analysts, however, have suggested that the government should rely instead on the "value of a statistical life year" (VSLY), in a way that would likely result in significantly lower benefits calculations for elderly people, and significantly higher benefits calculations for children. I urge that the government should indeed focus on statistical life-years rather than statistical lives. A program …

Enhancer Trapping Reveals Widespread Circadian Clock Transcriptional Control In Arabidopsis, Todd P. Michael, C Robertson Mcclung

Dartmouth Scholarship

The circadian clock synchronizes the internal biology of an organism with the environment and has been shown to be widespread among organisms. Microarray experiments have shown that the circadian clock regulates mRNA abundance of about 10% of the transcriptome in plants, invertebrates, and mammals. In contrast, the circadian clock regulates the transcription of the virtually all cyanobacterial genes. To determine the extent to which the circadian clock controls transcription in Arabidopsis, we used in vivo enhancer trapping. We found that 36% of our enhancer trap lines display circadian-regulated transcription, which is much higher than estimates of circadian regulation based on …

Science, Sexuality, And The Novels Of Huxley And Houellebecq, Angela C. Holzer

CLCWeb: Comparative Literature and Culture

In her article "Science, Sexuality, and the Novels of Huxley and Houellebecq," Angela C. Holzer begins with an introduction to recent discourse about contemporary culture by Francis Fukuyama, notably in his book Our Posthuman Future (2001). Next, Holzer introduces twentieth-century literary representations of genetic engineering. Focusing on Huxley's Brave New World (1932) and on Houellebecq's Les Particules élémentaires (1998), Holzer discusses differences in "utopian" literature when linked to metaphysical aspects of reproduction and that are owing to changes in the life sciences and medicine. Further, Holzer explores the implications for poetics resulting from scientific developments and relates Houellebecq's perspectives to …

Corpi, Murakami, And Contemporary Hardboiled Fiction, Cathy Steblyk

CLCWeb: Comparative Literature and Culture

In her paper, "Corpi, Murakami, and Contemporary Hardboiled Fiction," Cathy Steblyk discusses comparatively texts by contemporary detective fiction writers, one an ethnic-minority US-American and the other Japanese. Steblyk proposes that in detective fiction since the late 1980s, morally or ethically contestable sites of history have been given a postmortem by contemporary authors who are interested in restoring the lost parts of cultural histories. Detective fictions by feminist US-Chicana author Lucha Corpi and Japanese writer Murakami Haruki show how recent fiction from around the globe uses the hardboiled genre for the purposes of exploring past injustices and offering revisionist histories. The …

From The Inverted-U To The Extended-U: The Evolution Of A Law Of Psychology, Peter A. Hancock, H. C. Neil Ganey

Journal of Human Performance in Extreme Environments

The Yerkes-Dodson relationship is one of the oldest 'laws' behavioral research. It is used repeatedly as an explanation for stress effects on performance and is a fixture of undergraduate psychological texts. However, as is the case of most classics, it is more cited than read. In actuality, Yerkes and Dodson's report dealt with animal learning under states of compulsion and is only tangentially related to human performance in stress filled conditions. Our re-evaluation is motivated by two primary circumstances. The first is the evident failure of the unitary arousal notion, which has commonly been invoked as the causal source to …
