Attitudes Of Extension Professionals Toward Diversity Education In 4-H Programs, Patreese D. Ingram

Journal of Extension

America is becoming an increasingly diverse society. As an informal educational program for youth development, what role should 4-H programs have in helping youth learn about cultures that are different than their own? The purpose of this study was to examine the attitudes of Extension professionals toward diversity education in 4-H programs. Pennsylvania Extension professionals were surveyed regarding their attitudes toward the importance of diversity education and the recruitment of youth from different backgrounds. Although Pennsylvania Extension professionals were generally supportive of diversity in 4-H /youth development programs, there is clearly a need to strengthen diversity efforts and provide diversity …

Development Of A Firefly Luciferase-Based Assay For Determining Antimicrobial Susceptibility Of Mycobacterium Avium Subsp. Paratuberculosis, Stephanie L. Williams, N. Beth Harris, Raul G. Barletta

School of Veterinary and Biomedical Sciences: Faculty Publications

Paratuberculosis (Johne’s disease) is a fatal disease of ruminants for which no effective treatment is available. Presently, no drugs against Mycobacterium avium subsp. paratuberculosis (M. paratuberculosis), the causative agent of Johne’s disease, are approved for use in livestock. Additionally, M. paratuberculosis has been linked to a human chronic granulomatous ileitis (Crohn’s disease). To assist in the evaluation of antimicrobial agents with potential activity against M. paratuberculosis, we have developed a firefly luciferase-based assay for the determination of drug susceptibilities. The microorganism used was M. paratuberculosis K-10(pYUB180), a clinical isolate carrying a plasmid with the firefly luciferase gene. …

The Life Cycle Of A Horsehair Worm, Gordius Robustus (Nematomorpha: Gordioidea), Ben Hanelt, John J. Janovy Jr.

John J. Janovy, Jr. Publications

Aspects of the life cycle of the nematomorph Gordius robustus were investigated. Gordius robustus larvae fed to Tenebrio molitor (Coleoptera: Tenebrionidae) readily penetrated and subsequently encysted in the posterior portion of the midgut wall. Parasite development was then arrested in each infected beetle. Upon feeding these cysts to laboratory-reared Gryllus firmus. worm larvae developed to adults in the cricket hemocoel. In an additional experiment, G. robustus larvae fed to G. firmus did not develop to adults. These findings are in contrast to other studies that found direct infection to be an alternative mode of infection. This experiment is the …

Physiological And Morphological Correlates Of Presynaptic Inhibition In Primary Afferents Of The Lamprey Spinal Cord, I. V. Batueva, E. A. Tsvetkov, A. K. Sagatelyan, James T. Buchanan, N. Vesselkin, V. Adanina, E. I. Suderevskaya, J. -P Rio, J. Repérant

Biological Sciences Faculty Research and Publications

Patch-clamp recordings in a whole-cell mode were performed on dorsal sensory cells enzymatically isolated from the spinal cord of two lamprey species, Ichthyomyzon unicuspis and Lampetra fluviatilis. The voltage-activated currents through calcium channels were analysed. GABA and the specific GABA_B receptor agonist baclofen reduced the peak amplitude of inward Ba²⁺ current, as a robust alternate charge carrier through voltage-dependent Ca²⁺ channels. These effects were dose-dependent and reversible. GABA_B receptor antagonists, 2-hydroxysaclofen and δ-amino-n-valeric acid, blocked the reduction of Ba²⁺ currents by GABA and baclofen, while bicuculline, a GABA_A receptor antagonist, had no blocking …

Source Water Assessment Plan, Water Quality Division

Publications (WR)

The safe drinking water amendments of 1996 placed a strong emphasis on the goal to establish a nationwide effort to protect drinking water sources. As part of that goal, the legislation provided for a preliminary assessment of drinking water sources and an inventory of surrounding adjacent land use (ALUs). This nationwide effort will result in the first comprehensive look at the nation's drinking water sources from an assessment perspective. One of the outcomes of this nationwide assessment will be information that public water systems (PWSs) can use to help determine appropriate monitoring frequencies and to protect their sources of drinking …

Fas-Fasl Interaction Involved In Pathogenesis Of Ocular Toxoplasmosis In Mice, Mark S. Hu, Joseph D. Schwartzman, Grant R. Yeaman, Jane Collins, Rosanne Seguin, Imtiaz A. Khan, Lloyd H. Kasper

Dartmouth Scholarship

Ocular toxoplasmosis is a potentially blinding intraocular inflammation. The intent of this study was to investigate the role of Fas-FasL interaction in a murine model of acquired ocular toxoplasmosis induced by intracameral inoculation of Toxoplasma gondii. Intraocular inflammation, Fas and FasL expression on lymphocytes and on ocular tissues, the occurrence of apoptosis, and the frequency of CD8⁺ and CD4⁺ T cells in the infected eyes were analyzed in C57BL/6 (B6) mice. Susceptibility to parasite-induced intraocular inflammation was observed in Fas-deficient (B6-lpr) and FasL-deficient (B6-gld) mice. Inoculation of 5,000 T. gondii tachyzoites induced significant …

The Web Can Be Suitable For Learning, Gary C. Kessler, Ken Rosenblad, Steven D. Shepard

Security Studies & International Affairs - Daytona Beach

The authors discuss the advantages and difficulties of Web-based online distance learning. Web-based ODL can and does work for most learners when designed with high levels of interactivity and when cost and access issues can be adequately addressed. However, Web-based ODL requires a fundamental paradigm shift in how we define concepts like education and the classroom.

Are There Ways To Enhance China's Food Security?, B. Gardner Delworth, Yahui Zhao

Faculty Publications

Chinese officials and newspapers express considerable concern about the country's capacity to feed its huge and still growing population. The rhetoric will be familiar to people in Western countries as a blend of "agrarian fundamentalism" and "Malthusianism." But beyond the official rhetoric, we will argue that reforms in land ownership and irrigation water pricing and management could have highly salutary impacts on agricultural output that could alleviate food shortages far into the future.

Holgate Lake Study: An Examination Of The Issues Associated With Groundwater Flooding, John J. Lynch Jr., Heidi A. Mader, Mark Mccann

Master of Urban and Regional Planning Workshop Projects

This project examines Holgate Lake. Despite its natural hazard characteristics, the Holgate Lake area has not been immune to development pressure. Holgate Lake is an intermittent water body that forms when groundwater levels rise. Historical accounts show that the lake has formed at many different times in the last century. Because the lake fluctuates with the groundwater level, it is not necessarily present from year to year. As the area has developed, more and more people built in the location of the natural lakebed when the water was not present. When the lake level returned in the 1960's flooding of …

Identifying Effective And Efficient Methods To Educate Farmers About Soil Sampling, Robert N. King

Journal of Extension

This study compares three educational methods, (a) a slide set, (b) a pamphlet, and (c) a combination of slide set and pamphlet in identifying the most effective and efficient method of the three for educating 99 farmers about soil sampling. Both immediate and delayed post-tests were used in assessing attitudes about soil sampling, gains in immediate and long term knowledge, and preferences for educational methods. Farmers' attitudes did not adversely impact learning. However, farmers did lack prerequisite skills to correctly perform soil sampling. All three Extension methods were found to be effective with the pamphlet being the most efficient.

A New Artistic Rendering Of Izapa Stela 5: A Step Toward Improved Interpretation, John E. Clark

Journal of Book of Mormon Studies

Aided by creative techniques, Ajáx Moreno carefully prepared more accurate, detailed renderings of the Izapa monuments, including Stela 5, with its complex scenes of gods and other supernatural creatures, royalty, animals invested with mythic and value symbolism, and mortals. The author raises relevant questions about reconciling Jakeman’s view with the new drawing: Are there Old World connections? Can Izapa be viewed as a Book of Mormon city? Did the Nephites know of Lehi’s dream? Are there name glyphs on the stela? The scene, if it does not depict Lehi’s dream, fits clearly in Mesoamerican art in theme, style, technical execution, …

Bovine Follicular Dynamics, Oocyte Recovery,And Development Of Oocytes Microinjected With A Green Fluorescent Protein Construct, M S. Chauhan, S Nadir, T L. Bailey, A W. Pryor, S P. Butler, D R. Notter, William H. Velander, F C. Gwazdauskas

Papers in Biotechnology

The present study was carried out to 1) evaluate the viability of in vitro fertilized zygotes after microinjection of DNA, 2) assess the influence of oocyte quality upon the development rate of embryos when injected with DNA, and 3) determine the integration frequency of green fluorescent protein DNA into microinjected embryos. Oocytes were aspirated from ovaries of nine nonlactating Holsteins and were categorized into grades A, B, C, and D. At 16 h after in vitro fertilization, approximately half of the pronuclear stage presumptive zygotes were classified as having 1 pronucleus or 2 pronuclei, and they were microinjected with DNA …

System Simulation And Modeling Of Electronics Demanufacturing Facilities, Ketan Giridhar Limaye

Theses

Over the last decade, pressure on the electronic industry has been increasing as concerns for product take-back, product stewardship and global warming have continued to grow. Various end-of-life management options are being expanded including recycling to recapture values from basic materials through reengineering and recovery of subassemblies and individual components for remanufacturing. While progress has been reported on life cycle assessment (LCA), disassembly planning, design for disassembly, and design for environment (DFE), very little research has been focused on demanufacturing from a systems perspective.

The objective of this thesis is to build an interface between the user who knows the …

Preliminary Ecological Risk Assessment To Assess The Implications Of Replacing Chromium Plating With Tantalum Coating, Erik Jonathan Weiss

Theses

An ecological risk assessment process requires a modeling tool that can adapt to changing environmental conditions. Computer simulation tools are a useful means to develop an ecological risk assessment, because if properly used they can provide an organized framework to evaluate multiple data sources, complex problems and hypotheses. An evaluation was completed of the University of Tennessee CHEMS-1 model that ranks and scores contaminant toxicity and exposure potential. Tantalum posed less of a hazard than hexavalent chromium to the terrestrial and aquatic animals. Although, results indicated that the vanadium compounds, in particular vanadium pentoxide, presented the greatest hazard, with hexavalent …

A Field Study Coupling Soil Fractionation And Sonic Energy For Enhancing The In Situ Removal Of Volatile Organic Compounds In The Vadose Zone, Hassan Kaleem

Theses

Remediation of sites contaminated with hazardous wastes could be an expensive endeavor. There is, therefore, the need to explore techniques, which can reduce the remediation time and achieve regulatory specifications, thus reducing the cost involved in a site remediation exercise.

In this work, we investigated the use of sonic energy to enhance the in situ removal rate of trichloroethylene and dichloroethylene from a site in Hillsborough Township. New Jersey. The experiments were performed with and without sonic energy and each time the concentration of the trichloroethylene swept out from the site and the flowrate of the effluent gas were measured. …

A New Candidate In Arabia For The Valley Of Lemuel, George Potter

Journal of Book of Mormon Studies

The author serendipitously discovered a stream east of the Gulf of Aqaba that seems to share the physical features of Lehi’s “river of water” that “emptied into the Red Sea” and was “continually running.” The river Laman ran through the valley of Lemuel, described as “firm, steadfast, and immovable.” The stream and the canyon seem to fulfill the conditions of the river of Laman and the valley of Lemuel.

Near Eastern Weapon Parallels, Journal Of Book Of Mormon Studies

Journal of Book of Mormon Studies

Parallels between sickle swords and two-bladed knives in ancient Mesoamerica and the Near East may strengthen the possibility of some historical link between the areas. Similarities in weapons terminology may also lead to fruitful research.

Pre-Implantation Immunosuppression In The Pregnant Rat:A Possible Role Of Seminal Fluid, Omar A. Habbal, John M. Mclean

Sultan Qaboos University Medical Journal

Successful reproduction involves exposure of the female in significant antigenic challenge. These experiments were done to test the possibility/hypothesis that seminal fluid has an immunosuppressive role in the early stages cf pregnancy,which cculd pretect the conceptus from immonological attack. A highly inbred strain cf rat AO(RTI“) was used in this study. Eleven groups of animals were examined, one during the estrous phase of the ovarian cycle to provide base-line data, five during pseudopregnancy, designated as controls, and five groups during syngeneic pregnancy. Each group contained a minimum of six animals. For each animal, body weight and organ/tissue weightsocf the uterus, …
