Does Hunting Affect The Behavior Of Wild Pigs?, Oliver Keuling, Giovanna Massei
Does Hunting Affect The Behavior Of Wild Pigs?, Oliver Keuling, Giovanna Massei
Human–Wildlife Interactions
Wild boar and feral swine (Sus scrofa) numbers are growing worldwide. In parallel, their severe ecological and economic impacts are also increasing and include vehicle collisions, damage to crops and amenities, reduction in plant and animal abundance and richness, and transmission of diseases, the latter causing billions of U.S. dollars in losses to the livestock industry each year. Recreational hunters are the main cause of mortality for this species, and hunting has traditionally been the main method to contain populations of wild pigs. Hunting might affect the behavior of the species, which potentially can lead to these animals …

Data From: Yellow Air Day Advisory Study, Arthur J. Caplan
Browse all Datasets
Using a dataset consisting of daily vehicle trips, PM2.5 concentrations, along with a host of climactic control variables, we test the hypothesis that “yellow air day” advisories provided by the Utah Division of Air Quality resulted in subsequent reductions in vehicle trips taken during northern Utah’s winter-inversion seasons in the early 2000s. Winter inversions occur in northern Utah when climactic conditions are such that PM2.5 concentrations (derived mainly from vehicle emissions) become trapped in the lower atmosphere, leading to unhealthy air quality (concentrations of at least 35 µg/m3) over a span of what are called “red air days”. When concentrations …

The COVID-19 pandemic of 2020–2021 continues to impact all Utahns’ daily lives. Nationally, the Bureau of Labor Statistics, Pew Research Center, the Federal Reserve Bank, and sources such as the Wall Street Journal continue to report that women’s employment and careers have been disproportionately impacted during this time. Utah has seen similar negative impacts on working women. For example, the Kem C. Gardner Policy Institute at the University of Utah reported that from 2019 to 2020, jobs held by women declined at a rate more than double that of men, and unemployment rose more for females than males.
The Intersection Of Cultural Context And Research Encounter: Focus On Interviewing In Qualitative Research, Rebecca Yvonne Bayeck
The Intersection Of Cultural Context And Research Encounter: Focus On Interviewing In Qualitative Research, Rebecca Yvonne Bayeck
Instructional Technology and Learning Sciences Faculty Publications
This article discusses the influence of the cultural context on the interview process. With literature demonstrating the role of spatial context on interviews, the article contends that similar consideration should be given to cultural contexts of research studies. Focusing on the cultural context where the interview takes place and the interactions during the interview can help researchers understand and analyze interview material. Interview forms such as conversation/interview bombing emerged from the interaction of cultural context with the interview process. This points to the need for qualitative researchers to explore how the cultural context shapes their research encounter. Such focus will …

Contributors To Reduced Life Expectancy Among Native Americans In The Four Corners States, Olusola A. Omisakin, Hyojun Park, Max T. Roberts, Eric N. Reither
Sociology, Social Work and Anthropology Student Research
To assess trends in life expectancy and the contribution of specific causes of death to Native American-White longevity gaps in the Four Corners states, we used death records from the National Center for Health Statistics and population estimates from the U.S. Census Bureau from 1999–2017 to generate period life tables and decompose racial gaps in life expectancy. Native American-White life expectancy gaps narrowed between 2001 and 2012 but widened thereafter, reaching 4.92 years among males and 2.06 years among females in 2015. The life expectancy disadvantage among Native American males was primarily attributable to motor vehicle accidents (0.96 years), liver …

Human–Wildlife Interactions
Trapping of terrestrial animals is an important tool for harvest, pest control and research worldwide. To catch animals alive, animal welfare has to be ensured, which is reflected in different agreements on trading and trapping of animals between sovereign nations (Council Regulation [EEC] No 3254/91). The red fox (Vulpes vulpes) and stone marten (Martes foina) represent important predatory animals. Their influence on protected species as well as their increasing appearance in urban areas demand responsible handling. In our study, we evaluated 2 trap systems used for trapping red foxes and stone martens in accordance with criteria stipulated in the Agreement …

Human–Wildlife Interactions
Wild pigs (Sus scrofa) are a non-native, invasive species that cause considerable damage and transmit a variety of diseases to livestock, people, and wildlife. We explored Twitter, the most popular social media micro-blogging platform, to demonstrate how social media data can be leveraged to investigate social identity and sentiment toward wild pigs. In doing so, we employed a sophisticated machine learning approach to investigate: (1) the overall sentiment associated with the dataset, (2) online identities via user profile descriptions, and (3) the extent to which sentiment varied by online identity. Results indicated that the largest groups of online …

Small Satellite Conference
The subtropical waters between Hawaii and California are currently infested with an accumulation of plastic estimated to be twice the area of Texas, otherwise known as the Great Pacific Garbage Patch (GPGP). This paper presents a novel CubeSat mission to monitor the size, growth and position of the GPGP. At 1.6 million square kilometres, the GPGP is by far the largest and most serious accumulation of garbage out of the five patches littered across the world’s oceans. If we are to prevent further damage to the marine ecosystems, it is imperative we act with the utmost urgency. Leveraging recent technological …

Small Satellite Conference
The origin of the cosmic diffuse gamma-ray (CDG) background in the 0.3 – 30 MeV energy range is a mystery that has persisted for over 40 years. The Mini Astrophysical MeV Background Observatory (MAMBO) is a CubeSat mission concept motivated by the fact that, since the MeV CDG is relatively bright, only a small detector is required to make high-quality measurements of it. Indeed, the sensitivity of space-based gamma-ray instruments to the CDG is limited not by size, but by the locally generated instrumental background produced by interactions of energetic particles in spacecraft materials. Comparatively tiny CubeSat platforms provide a …
Globalstar Stx3 To Stx4/Spotx: An Evolution From Global Simplex To Global Duplex Communications For 1u Cubesats And Larger Vehicles, Andrew Santangelo
Globalstar Stx3 To Stx4/Spotx: An Evolution From Global Simplex To Global Duplex Communications For 1u Cubesats And Larger Vehicles, Andrew Santangelo
Small Satellite Conference
The STX3 module is used in devices from the LinkStar-TRK satellite radio system to SPOT locators used on the ground providing global beaconing services for a range of systems and applications such as cubesats, aircraft, ships at sea, and pipeline monitoring systems to name a few. For cubesats and small satellites the STX3 and the STX3 based LinkStar-TRK provides an invaluable low cost global data communications system. However a key drawback is the module only provides one-way “simplex” communications–there is not a mechanism to send messages and commands globally up to the satellite via the STX3 module. Per FCC regulations …

Simulating The Storm Environment Responsible For Nepal's First Observed Tornado, Jonathan David Douglas Meyer, Binod Pokharel, Robert R. Gillies
Plants, Soils, and Climate Faculty Publications
A high-resolution numerical forecast model was used to simulate the meteorological conditions leading up to the March 31st, 2019 severe weather event that produced Nepal's first-ever observed tornado. The sparse meteorologic observations in the region capturing the storm environment limit the ability to anticipate another similar situation should the particular set of conditions present themselves again. This study presents a multifaced view of the storm environment through 1) a synoptic perspective provided by the Global Data Assimilation System (GDAS) reanalysis dataset and 2) a trio of progressively higher resolution one-way nested simulations (12 km–4km–1km) driven by GDAS boundary conditions to …

Computer Science Student Research
Purpose: With the rapid deployment of Internet of Things (IoT) technologies, it has been essential to address the security and privacy issues through maintaining transparency in data practices. The prior research focused on identifying people’s privacy preferences in different contexts of IoT usage, and their mental models of security threats. However, there is a dearth in existing literature to understand the mismatch between user’s perceptions and the actual data practices of IoT devices. Such mismatches could lead users unknowingly sharing their private information, exposing themselves to unanticipated privacy risks. We aim to identify these mismatched privacy perceptions in our work. …

A Versatile And Open-Source Radio Framework For The D3 Cubesat Mission, Carlos Carrasquillo
Small Satellite Conference
This paper details the design and implementation of the communications system for the Drag De-OrbitDevice (D3) CubeSat mission. The D3 mission aims to validate the effectiveness of a novel approach to aerodynamically-based orbital maneuvering and controlled re-entry. Using four deployable tape-spring booms that can be retracted to any intermediate length, the D3 can accurately modulate the ballistic coefficient profile of the CubeSat in low Earth orbit (LEO). To compute the necessary boom deployment and reproduce a desired trajectory, the guidance profile of the CubeSat must be actively generated, which itself is a very computationally intensive process. The guidance will therefore …

Constellation Forecasting Tools For Autonomous Operations, Alexander Dunn, Joe Miceli, Michael Reher
Small Satellite Conference
Large constellations are quickly becoming the norm in small satellite missions. These constellations are being designed and developed faster than ever before through the utilization of smaller, heterogeneous spacecraft. Often, these constellations provide increased resiliency and capabilities over their heritage, highly tailored counterparts. The ability to replace on-orbit assets quickly and with lower costs is an advantageous feature of these large smallsat constellations. With the advent of these new architectures, though, come increased complexity in mission operations. The management and monitoring of potentially hundreds of heterogeneous space assets can be extremely challenging and negate much of the cost savings using …

Design And Validation Of An Autonomous Mission Manager Towards Coordinated Multi-Spacecraft Missions, Antony Gillette, Alan George, J. Patrick Castle
Small Satellite Conference
For ambitious upcoming aerospace missions, autonomy will play a crucial role in achieving complex mission goals and reducing the burden for ground operations. Standalone spacecraft can leverage autonomy concepts to optimize data collection and ensure robust operation. For spacecraft clusters, autonomy can additionally provide a feasible method of ensuring coordination through onboard peer-to-peer scheduling. However, in exchange for providing flexible mission capabilities and operational convenience, autonomy introduces additional uncertainty and software complexity, which complicates the mission assurance process. This research presents a framework for designing and testing schedules consisting of heavily constrained tasks.
The core of this framework, the Schedule …

Recent breakthroughs in technology have led to a thriving “new space” culture in low-Earth orbit (LEO) in which performance and cost considerations dominate over resilience and reliability as mission goals. These advances create a manifold of opportunities for new research and business models but come with a number of striking new challenges. In particular, the size and weight limitations of low-Earth orbit small satellites make their successful operation rest on a fine balance between solar power infeed and the power demands of the mission payload and supporting platform technologies, buffered by on-board battery storage. At the same time, these satellites …

A Wave Physics Approach To Electronically Steerable Antennas, Jean-Baptiste Gros, Vladislav Popov, Mikhail Odit, Geoffroy Lerosey
Small Satellite Conference
Electronically steerable antennas, that are compact, thin, light and contain no mechanical parts, are being more and more used for satcom applications on the ground, notably owing to the fast development of mega constellations; yet their use is still very limited on board. Indeed, all designs up to date rely on the same old concept, phased arrays, namely, a large number of sources that are phased matched to point in various directions. These can be passive, in the sense that a common feed is used to radiate through many radiators, or active in which case each tiny emitter contains its …

Neodothiora populina Crous, G.C. Adams & Winton was determined to be a new pathogen of trembling aspen (Populus tremuloides) growing in Alaska, based on completion of Koch’s Postulates in replicated forest and growth chamber inoculation trials. The pathogen is responsible for severe damage and widespread rapid mortality of sapling to mature aspen (≥ 80 years) in the boreal forests of interior Alaska, due to large diffuse annual (1–2 years) cankers. Isolation of the pathogen was challenging, and identification based on cultural characters was difficult. Fruiting bodies were not found on wild diseased trees, but erumpent pycnidia were found …
