This study examined the similarities and differences among 171 Grade 7-12 science teachers from three different countries (54 U.S, 63 Bolivian, and 54 Turkish) with respect to their attitudes toward environmental education (EE) and instructional practices. The instrument employed explored how teachers‘ knowledge, instructional practices, decisionmaking process, and cultural features influenced their EE attitudes and praxis. The instrument, which was translated into Spanish and Turkish and then back into English, contained a personal data form that included demographic questions and a three-part questionnaire. Based on the analysis completed, significant differences were found between these three countries with respect to 1) …

Mule Deer: A Handbook For Utah Hunters And Landowners, Dennis D. Austin

All USU Press Publications

Mule deer are a familiar sight to residents of Utah and the Intermountain West. Sportsmen hunt them, others seek a glimpse of them while hiking or camping, drivers dodge them, and homeowners sometimes delight, sometimes fret as deer visit backyards and gardens. Deer, many of which live in the towns, cities, and farms that sprawl over their historical habitat, sometimes seem ubiquitous. Useful information about them, either scientific or practical, is less widespread. In this handbook, Dennis Austin fills that need for information, offering a one-stop reference packed with up-to-date knowledge and practical advice on mule deer. Data on deer …

Measurement Methods Of Electron Emission Over A Full Range Of Sample Charging, R. C. Hoffman, John R. Dennison

All Physics Faculty Publications

The electron emission properties of a material subject to incident radiation flux are key parameters in determining to what equilibrium charge a spacecraft will established under given environmental conditions. However, there is a complex relation between these emission properties and the charge built up in spacecraft insulators. Complex modeling codes have been developed to predict the potential a spacecraft will adopt as a consequence of its interaction with the space plasma. These require correct models of the electron yields as a function of charge to accurately predict the both the charge build up and the equilibrium potential of spacecraft components. …

Classroom Instructions Observed From The Perspectives Of Current Reform In Science Education: Comparisons Between Korean And U.S. Classrooms., Todd Campbell, P. S. Oh, M. Shin, D. Zhang

Teacher Education and Leadership Faculty Publications

This research investigated the similarities and differences between Korean and U.S. 9-12th grade science classrooms. The Reformed Teaching Observation Protocol was used to observe sixty-six classrooms (26 Korean and 40 U.S.) to examine the extent to which principles of constructivism framing both Korean and U.S. standards documents were observed. Through quantitative methods the findings revealed generally more similarities than differences when comparing Korean and U.S. classrooms. This was evidenced by the lack of overall significant differences in how the classrooms were rated, as well as the lack of overall significant differences in each subscale of reformed teaching measured by the …

Hot Water, Dry Streams: A Tale Of Two Trout, Jack R. Tuholske

All In-stream Flows Material

Norman Maclean’s timeless memoir A River Runs Through It begins with the reflection that in his household “there was no clear line between religion and fly fishing.”¹ That zeal remains today; nearly 30 million Americans call themselves fishermen.² Anglers devoted an aggregate of 517 million user-days pursuing their passion in 2006 and spent billions of dollars to support it.³ Fishing in the western United States holds a special place in fishing lore the world over and for good reason. From the great trout waters of Montana, to the salmon-laden rivers of the west coast, to the sparkling …

Genetic Characteristics And Environmental Parameters For Growing Turfgrass In Closed And Retractable Dome Stadiums, Bruce Bugbee, Paul Johnson

Turfgrass

Our analysis indicates that electric lighting for turfgrass growth is highly cost effective, if it is coupled with appropriate genetic and environmental changes.

Inadequate light levels for vigorous turf growth is the key challenge associated with growing turf in enclosed and retractable dome stadiums. The light levels of closed stadiums are too low to maintain vigorous plant growth that can quickly recover from the damage caused by athletic events. As a solution, retractable-dome stadiums have been built. However, even with the roof open, light levels in these stadiums are less than half of natural sunlight because of shading from the …

Rehabilitate Failing Park Sewage System Environmental Assessment, United States Department Of The Interior, National Park Service

Environmental Assessments (UT)

The National Park Service (NPS) proposes to rehabilitate the failing sewage system within Bryce Canyon National Park, Utah. The rehabilitation would provide a safe, healthy, and functional environment, and maintain public health and future service for park visitors and staff. Portions of the sanitary sewage collection system were originally constructed in 1958 of clay pipe and currently service the lodge, staff housing, and visitor center before feeding into sewage treatment lagoons. Sections of the sewage system have deteriorated significantly with age. These sections of the system and appurtenant manholes are deteriorating into pieces that regularly clog the system and cause …

Examining The Compatibility Between Forestry Incentive Programs In The Us And The Practice Of Sustainable Forest Management, Steven E. Daniels, Michael A. Kilgore, Michael G. Jacobsen, John L. Greene, Thomas J. Straka

Sociology, Social Work and Anthropology Faculty Publications

This research explores the intersection between the various federal and state forestry incentive programs and the adoption of sustainable forestry practices on non-industrial private forest (NIPF) lands in the US. The qualitative research reported here draws upon a series of eight focus groups of NIPF landowners (two each in Minnesota, Oregon, Pennsylvania, and South Carolina). Despite minor regional variations, the dominant theme that emerged is that these landowners’ purchase and management decisions are motivated by the “trilogy” of forest continuity, benefit to the owner, and doing the “right thing.” This trilogy is quite consistent with notions of sustainable forestry, but …

Xperts And Novices: Differences In Their Use Of Mental Representation And Metacognition In Engineering Design, Raymond Anthony Dixon

Dissertations

Research shows that mental representation such as analogical reasoning is a fundamental cognitive tool for design problem solving (Daugherty & Mentzer, 2008; Hey, Lensey, Agogino, & Wood, 2008; Lewis, 2008). Not much is known, however, about the way students and professional engineers actively generate and change their mental representation when solving a engineering design problem. There are very few studies that show how different types of mental representations; such as metaphors, propositions, and analogies; interplay with higher order cognitive processes; such as planning, monitoring, and evaluation; as engineering designers navigate their problem and solution spaces. This empirical study investigated the …

The Influence Of Culture Medium And Light Cycle On The Productivity Of The Green Algae Neochloris Oleoabundans, Candace Clark

Browse All Undergraduate research

Biofuels from algae are a promising source of alternative energy. One algae species, Neochloris oleoabundans, shows potential for successful biodiesel production, where biodiesel is produced from the neutral lipid content of the algae. Algal neutral lipid content may be influenced and increased by changes in the surrounding environment. One possible way to influence lipid synthesis is through the growth medium. Two published growth mediums were compared using photobioreactors. Two experimental runs were performed with each medium: 1) continuous light and 2) 12 hour on, 12 hour off light cycle. In addition to medium composition, the effect of light cycle on …

Regeneration Response And Seedling Bank Dynamics On A Dendroctonus Rufipennis-Killed Picea Engelmannii Landscape, R. Justin Derose, James N. Long

Aspen Bibliography

Question: How does regeneration response to a host- specific, high-severity, infrequent Dendroctonus rufipennis outbreak differ from our conceptualization of high-severity, infrequent/low-severity, frequent disturbance regimes in Picea engelmannii - Abies lasiocarpa communities? Location: Southern Utah, USA. Methods: One hundred and seven plots across a high- elevation P. engelmannii forest were sampled to re- construct pre-outbreak overstory and seedling bank densities, and calculate their associated metrics of diversity. Decade of establishment by seedling bank trees indicated ‘‘chronic’’ and ‘‘pulse’’ regenerators. Results: The post-outbreak overstory and seedling bank were dominated by A. lasiocarpa. Although Pinus flexilis, Pinus ponderosa, Picea pungens, and Psuedotsuga menziesii …

Propagating Trembling Aspen From Root Cuttings: Impact Of Storage Length And Phenological Period Of Root Donor Plants, Jessica Snedden, Simon M. Landhausser, Victor J. Lieffers, Lee R. Charleson

Aspen Bibliography

Two experiments were conducted to examine the effects of growing conditions, duration of cold storage, and distinct phenological periods of root donor plants on the propagation success of aspen rootlings. Root donor plants were produced either under greenhouse or open grown conditions. Root cuttings were periodically collected from donor plants that had been stored for various lengths of time in cold storage (up to 180 days), or that were stored dormant in cold storage (up to 150 days) and then grown for another full growing season. Longer storage of donor plants produced only slightly smaller rootlings and resulted in slightly …

Absence Of Predation Eliminates Coexistence: Experience From The Fish-Zooplankton Interface, Z. M. Gilwicz, Wayne A. Wurtsbaugh, E. Szymansk

Watershed Sciences Faculty Publications

Examples from fishless aquatic habitats show that competition among zooplankton for resources instigates rapid exclusion of competitively inferior species in the absence of fish predation, and leads to resource monopolization by the superior competitor. This may be a single species or a few clones with large body size: a cladoceran such as Daphnia pulicaria, or a branchiopod such as Artemia franciscana, each building its population to a density far higher than those found in habitats with fish. The example of zooplankton from two different fish-free habitats demonstrates the overpowering force of fish predation by highlighting the consequences of its absence. …

Development Of A New Tacaribearenavirus Infection Model And Its Use To Explore Antiviral Activity Of A Novelaristeromycin Analog, Brian B. Gowen, M. H. Wong, D. Larson, W. Ye, K. H. Jung, E. J. Sefing, Ramona T. Skirpstunas, Donald F. Smee, John D. Morrey, S. W. Schneller

Animal, Dairy, and Veterinary Science Faculty Publications

Background

A growing number of arenaviruses can cause a devastating viral hemorrhagic fever (VHF) syndrome. They pose a public health threat as emerging viruses and because of their potential use as bioterror agents. All of the highly pathogenic New World arenaviruses (NWA) phylogenetically segregate into clade B and require maximum biosafety containment facilities for their study. Tacaribe virus (TCRV) is a nonpathogenic member of clade B that is closely related to the VHF arenaviruses at the amino acid level. Despite this relatedness, TCRV lacks the ability to antagonize the host interferon (IFN) response, which likely contributes to its inability to …
