Increased Hippocampal Probdnf Contributes To Memory Impairments In Aged Mice, Mona Buhusi, Chris Etheredge, Ann-Charlotte Granholm, Catalin V. Buhusi

Psychology Faculty Publications

Memory decline during aging or accompanying neurodegenerative diseases, represents a major health problem. Neurotrophins have long been considered relevant to the mechanisms of aging-associated cognitive decline and neurodegeneration. Mature Brain-Derived Neurotrophic Factor (BDNF) and its precursor (proBDNF) can both be secreted in response to neuronal activity and exert opposing effects on neuronal physiology and plasticity. In this study, biochemical analyses revealed that increased levels of proBDNF are present in the aged mouse hippocampus relative to young and that the level of hippocampal proBDNF inversely correlates with the ability to perform in a spatial memory task, the water radial arm maze …

Relational Values Resonate Broadly And Differently Than Intrinsic Or Instrumental Values, Or The New Ecological Paradigm, Sarah Klain, Paige Olmsted, Kai M. A. Chan, Terre Satterfield

Environment and Society Faculty Publications

Value orientations used to explain or justify conservation have been rooted in arguments about how much and in what context to emphasize the intrinsic versus instrumental value of nature. Equally prominent are characterizations of beliefs known as the New Ecological Paradigm (NEP), often used to help explain pro-environmental behaviour. A recent alternative to these positions has been identified as ‘relational value’—broadly, values linking people and ecosystems via tangible and intangible relationships to nature as well as the principles, virtues and notions of a good life that may accompany these. This paper examines whether relational values are distinct from other value …

Schrödinger, 3, David Peak

The 3D infinite square well: quantum dots, wells, and wires

In the preceding discussion of the Schrödinger Equation the particle of interest was assumed to be “moving in the x -direction.” Of course, it is not possible for a particle to be moving in one spatial direction only. If that were true, according to the HUP it could be anywhere in the y - and z -directions and therefore be undetectable with finite volume detectors. Now, we consider the more realistic case of motion in all three spatial directions. For this purpose, we start with the 3D infinite square well. …

Initiating Cultural Shifts In Perceptions Of Cataloging Units Through Interaction Assessment, Andrea Payant, Becky Skeen, Liz Woolcott

Library Faculty & Staff Publications

Points of contact formulate the culture of any organization and shape the perceptions of decision makers and colleagues alike. This research project investigated the interactions between Cataloging and Metadata Services staff and other library employees by analyzing interactions. This article summarizes the results of data gathered from interaction assessments and compares them with surveys about the current perceptions of the cataloging unit at the Utah State University Libraries. It discusses the ways these results have influenced existing unit workflows to enhance awareness of cataloging and metadata contributions to the library and posits possible ways to continue such initiatives moving forward.

Should Universities Abandon Placement Exams?, Rachel Robinson-Greene

Languages, Philosophy, and Communication Studies Faculty Publications

At most universities in the United States, students are required to take placement exams to determine their developmental level in math and English. Students are placed in classes that are appropriate for a student at that developmental level in each of those disciplines. Students who are placed in non-college ready, remedial classes are required to take up to three such classes before they can enroll in courses that actually count toward their degree. Last week, the Chancellor of the California State University educational system issued an executive order doing away with placement exams. Instead, students can try their hands at …

An Electric sail, a propellant-less propulsion system, uses solar wind ions to rapidly travel either to deep space or the inner solar system. Scientific spacecraft could reach Pluto in ~5 years, or the boundary of …

Operating Small Sat Swarms As A Single Entity: Introducing Soda, Tracie Conn, Andres Perez, Laura Plice, Michael Ho

Small Satellite Conference

NASA’s decadal survey determined that simultaneous measurements from a 3D volume of space are advantageous for a variety of studies in space physics and Earth science. Therefore, swarm concepts with multiple spacecraft in close proximity are a growing topic of interest in the small satellite community. Among the capabilities needed for swarm missions is a means to maintain operator-specified geometry, alignment, or separation. Swarm stationkeeping poses a planning challenge due to the limited scalability of ground resources. To address scalable control of orbital dynamics, we introduce SODA – Swarm Orbital Dynamics Advisor – a tool that accepts high-level configuration commands …

Seasonal Development Of The Biological Control Agent Of Dalmatian Toadflax, Mecinus Janthiniformis (Curculionidae: Coleoptera), In Utah: Phenology, Overwintering Success, And Mortality, Samantha A. Willden

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

By outcompeting desirable vegetation, invasive weeds can dominate field crops and rangelands, drastically reducing yield and land value. One option in controlling the impact and spread of such weeds is reuniting them with their natural insect herbivores, a process called biological control. When successful, biocontrol can be the cheapest way to provide long-term control of invasive weeds, but continual monitoring of insect and weed activity is required to ensure success.

Dalmatian toadflax is an invasive weed that occurs widely throughout the northwestern U.S., and that is spreading south each year to warmer and drier regions, including sites in Utah. Although …

Resolving Spatial And Temporal Variability In Dissolved Organic Matter Characteristics Within Combined Agricultural And Stormwater Conveyances, Bryce A. Mihalevich

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

In many urban areas, stormwater runoff can threaten the ecological health of streams and downstream water bodies. Due to the increased impervious nature of urban landscapes, runoff is more “flashy” and as a result, high concentrations of pollutants can be transported in shorter periods of time than in more natural environments. One pollutant of concern is dissolved organic matter (DOM). DOM is important within aquatic ecosystems, but excess amounts can cause depletion in dissolved oxygen concentrations and can negatively affect aquatic organisms. This study investigated changes in DOM quantity and sources within the Northwest Field Canal (NWFC), an urban water …

Using Silkworms As A Host To Spin Spider Silk-Like Fibers, Xiaoli Zhang

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Using silkworms as the potential host to spin spider silk-like fibers is an area of intense research world-wide. The conventional methods used to create transgenic silkworms hosting spider silk-like gene limits the incorporation of spider silk-like protein and do not improve the mechanical performance of the composite silkworm/spider silk fibers. In this dissertation, synthetic spider ampullate genes were incorporated into the precise site of the fibroin heavy chain or light chain using the latest genome editing technology CRISPR/cas9 guided non-homologous end joining as opposed to conventional random integration using transposon-based piggyBac system. These protocols, with extensive applicability to other silkworm …

The Past That Was Differs Little From The Past That Was Not: Pictographs And Petroglyphs In Cormac Mccarthys Blood Meridian Or The Evening Redness In The West, Cami Ann Dilg

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

This literary analysis expands the scholarly canon concerning Cormac McCarthy’s regional writing by identifying the purpose of pictographs and petroglyphs in Blood Meridian or the Evening Redness in the West (1985). Not only do pictographs and petroglyphs tie the narrative to place, but they create a commentary regarding the erasure of Native American histories in the United States. These images record Native American memory and presence in the landscape, and by referencing them, McCarthy confronts concepts of exposure and shame, which facilitates conversations concerning Native American genocide. A close analysis of character interaction with and scene placement of these images …

Experiences And Perceptions Of Human Vulnerability To Climate Change In Calakmul, Mexico, Lisa Green

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

This report explores how residents of Calakmul, Mexico perceive and experience their own vulnerability to climate change, and how these perceptions and experiences are differentiated among communities, households, and individuals. Fifty-five semi-structured interviews in 2013 and 45 follow-up interviews in 2016 provide data on familiarity with climate change and perceived effects of climate-related stressors on livelihood activities, health, and experiences of hunger. We found that coping responses to the effects of climate change often require cash inputs, and communities are differentiated in their experiences of vulnerability, based in part on their access to wage labor and importantly governmental support.

Natural And Anthropogenic Effects On Life History Characteristics In The Side-Blotched Lizard (Uta Stansburiana), Geoffrey David Stuart Smith

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Survival is a prerequisite for successful reproduction, and is thus intertwined with fitness. Some physiological systems can improve survival, like the immune system, but compete with other processes for resources. Because animals evolved with resource limitation, it is important to understand how these resource-allocation decisions are made. To meet this end, I performed four investigations addressing how life-history characteristics shift in side-blotched lizards (Uta stansburiana) using laboratory studies and multi-year field sampling. First, I measured metabolic rates in response to different immune challenges and different energy states in male lizards. I found that, surprisingly, cutaneous biopsies were associated …

Integrating Black Bear Behavior, Spatial Ecology, And Population Dynamics In A Human-Dominated Landscape: Implications For Management, Jarod D. Raithel

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The American black bear (Ursus americanus) has made a robust recovery within the human-dominated, social-ecological systems characterizing the Mid-Atlantic United
States. For example, in northwestern New Jersey (NJ), USA, black bear abundance increased from an estimated 450-500 in 1996 to 3200-3400 in 2010. Bear recovery
coincided with increasing human populations, coupled with shifting settlement patterns toward sprawling suburban communities. Consequently, conflicts have rapidly proliferated over the past three decades and resulted in >1400 incidents of verified property damage, >400 livestock kills, >250 pet attacks and/or kills, seven human attacks and one human fatality since 2001. The New Jersey …
