An Analysis Of Hybrid/Remote Work Eligibility In Academic Librarian Job Advertisements, Ruth S. Connell, Meris Mandernach Longmeier

Library Faculty Publications

This paper seeks to capture changing policies and approaches to hybrid and remote work in academic libraries following the COVID-19 pandemic. For this study, job advertisements were gathered and those hiring managers surveyed. Results show hybrid/remote positions have competitive salaries, many types of academic library positions have hybrid eligibility, and campus and library policies regarding hybrid/remote work and their inclusion in job postings continue to evolve. Despite the potential recruitment benefits of these flexible work arrangements, many who offer them are not including this information in their job advertisements; therefore, job candidates should ask or negotiate for this benefit.

Laboratory Evaluation And Field Demonstration Of Cold In-Place Recycling Asphalt Mixture In Michigan Low-Volume Road, Dongzhao Jin, Lei Yin, Lance Malburg, Zhanping You

Michigan Tech Publications, Part 2

Cold-in place recycling (CIR) is a promising technology for the rehabilitation of asphalt pavements. However, the CIR asphalt pavement constructed in the field often has high air voids due to the presence of moisture during construction, and the moisture susceptibility of the pavement is crucial in determining its service life. Therefore, the objective of this research was to assess the laboratory performance of CIR asphalt mixes under freeze-thaw conditions (The mix prior to being subjected to freezing and thawing is labeled as "dry condition", while the mix that was placed in a refrigerator at –18 °C for 16 h and …

Bikeability Disparities In Orange County, California: Intersection Of Place And Demographics, Jeanette Gritton, Maria Cristina Martinez, Georgiana Bostean, Megan Thiele Strong

Sociology Faculty Articles and Research

Active transportation modes such as walking and biking are gaining popularity for their extensive health and environmental benefits, yet scholars know little about how place-based accessibility varies by area sociodemographic composition. This study is among the first to examine sociodemographic disparities (by both race and socioeconomic status) in bikeability while allowing for heterogeneity in disparities. Consideration of bikeability disparities is particularly critical within the framework of urban planning concepts that promote equitable accessibility and reduced dependency on automobiles, such as the 15-minute city. Geographically Weighted Regressions examined associations between census tract-level bikeability (using an index that combines five components), socioeconomic …

Visitor Use Management: How The Timed Entry Permit Reservation System At Parks And Protected Areas Influence The Perception Of Sustainable Recreation And Impact Visitor Motivations, Cassandra L. Onufrak

Masters Theses

Parks and protected areas across the United States have undergone substantial change in recent years, specifically pertaining to visitation trends and patterns. National parks have endured rapid growth in park visitation and popular attractions within park boundaries now experience a high visitor concentration and traffic. As visitation within national parks increases, there is a high probability that visitor-related impacts, such as vegetation trampling, wildlife disturbance, soil erosion, and intra-visitor conflict, are also likely to increase. Visitors are more likely to feel crowded and rushed, and ultimately label their park experience as low or poor quality. Through the use of Visitor …

To What Extent Do Water Reuse Treatments Reduce Antibiotic Resistance Indicators? A Comparison Of Two Full-Scale Systems, Ishi Keenum, Jeanette Calarco, Haniyyah Majeed, E. Eldridge Hager-Soto, Charles Bott, Emily Garner, Valerie J. Harwood, Amy Pruden

Michigan Tech Publications, Part 2

Water reuse is an essential strategy for reducing water demand from conventional sources, alleviating water stress, and promoting sustainability, but understanding the effectiveness of associated treatment processes as barriers to the spread of antibiotic resistance is an important consideration to protecting human health. We comprehensively evaluated the reduction of antibiotic resistance genes (ARGs) and antibiotic-resistant bacteria (ARB) in two field-operational water reuse systems with distinct treatment trains, one producing water for indirect potable reuse (ozone/biologically-active carbon/granular activated carbon) and the other for non-potable reuse (denitrification-filtration/chlorination) using metagenomic sequencing and culture. Relative abundances of total ARGs/clinically-relevant ARGs and cultured ARB were …

Computer Science Student Research

Streamflow prediction is crucial for planning future developments and safety measures along river basins, especially in the face of changing climate patterns. In this study, we utilized monthly streamflow data from the United States Bureau of Reclamation and meteorological data (snow water equivalent, temperature, and precipitation) from the various weather monitoring stations of the Snow Telemetry Network within the Upper Colorado River Basin to forecast monthly streamflow at Lees Ferry, a specific location along the Colorado River in the basin. Four machine learning models—Random Forest Regression, Long short-term memory, Gated Recurrent Unit, and Seasonal AutoRegresive Integrated Moving Average—were trained using …

Next-Generation Crop Monitoring Technologies: Case Studies About Edge Image Processing For Crop Monitoring And Soil Water Property Modeling Via Above-Ground Sensors, Nipuna Chamara

Dissertations and Doctoral Documents from University of Nebraska-Lincoln, 2023–

Artificial Intelligence (AI) has advanced rapidly in the past two decades. Internet of Things (IoT) technology has advanced rapidly during the last decade. Merging these two technologies has immense potential in several industries, including agriculture.

We have identified several research gaps in utilizing IoT technology in agriculture. One problem was the digital divide between rural, unconnected, or limited connected areas and urban areas for utilizing images for decision-making, which has advanced with the growth of AI. Another area for improvement was the farmers' demotivation to use in-situ soil moisture sensors for irrigation decision-making due to inherited installation difficulties. As Nebraska …

Spatiotemporal Analysis Of Soil Quality Degradation And Emissions In The State Of Iowa (Usa), Elena A. Mikhailova, Hamdi A. Zurqani, Lili Lin, Zhenbang Hao, Christopher J. Post, Mark A. Schlautman, Gregory C. Post

Geography Faculty Publications and Presentations

The concept of soil quality (SQ) is defined as the soil's capacity to function, which is commonly assessed at the field scale. Soil quality is composed of inherent (soil suitability) and dynamic (soil health, SH) SQ, which can also be analyzed using geospatial tools as a SQ continuum (SQC). This study proposes an innovative spatiotemporal analysis of SQ degradation and emissions from land developments using the state of Iowa (IA) in the United States of America (USA) as a case study. The SQ degradation was linked to anthropogenic soil (SD) and land degradation (LD) in the state. More than 88% …

Uniform Intelligence: The United States Military Liaison Mission And The Cold War 1947-1990, Frank Christopher Ofner

Doctoral Dissertations and Projects

On May 7, 1945, Germany surrendered unconditionally to the Allied Powers, ending the war in Europe. As such, the Western Allies of Britain, France, and the United States came into direct contact with the Soviet forces in Germany, which they divided into four zones of occupation. With the potential of an armed conflict over Germany, the Western Allies and the Soviets agreed to use military liaison missions to help foster communication in Germany. The British and French maintained their units: British Commanders in Chief Mission to the Soviet Forces in Germany (BRIXMIS) and La Mission Militaire Francaise de Liaison (FMLM …

Soil Stabilization With Gypsum: A Review, Yasaman Abdolvand, Mohammadhossein Sadeghiamirshahidi

Michigan Tech Publications, Part 2

The demand for sustainable ground improvement methods is rising as urban development expands into areas with challenging soil conditions. Traditional approaches, mostly reliant on cement and lime, contribute significantly to anthropogenic greenhouse gas emissions. Researchers, therefore, are constantly searching for new environmentally friendly stabilization methods to improve the engineering properties of soils. One alternative material used for this purpose is gypsum in its hydrated and dehydrated (hemihydrate/anhydrate) states. Not only can natural gypsum be used for ground improvement but also industrial waste and by-products (e.g. used or waste plasterboard, phosphogypsum, flue gas desulfurization gypsum, titanium dioxide production gypsum by-product) can …

This paper provides an overview of the application of space-based technologies, specifically Geographic Information Systems (GIS) technology and rocket cargo launches, to disaster management operations. GIS links data from satellites, remote sensing, and other sources to dashboards, allowing relief teams to monitor relevant demographic, environmental, and disaster details. This information supports multiple aspects of planning and decision-making in the preparedness, response, and relief stages of the disaster management cycle. Rocket cargo transportation, an emerging method of shipping supplies, will allow for supplies to be shipped anywhere in the world in under twenty-four hours. This can be used in a future …

Supply, Demand, And Fiscal Sustainability Of Outdoor Recreation In Utah, Jordan W. Smith, Chris Monz

Environment and Society Faculty Publications

Because Utah's outdoor recreation destinations are managed by several different federal and state agencies, there is no comprehensive and consistent information on the amount and types of outdoor recreation resources available within the state. Additionally, there has been no research to date on how state programs whose revenues are dependent on outdoor recreation activity, are likely to fare in the coming years. This report begins to address these limitations by: 1) compiling and synthesizing data that characterize the amount and location of outdoor recreation resources throughout the state; and 2) presenting the results of a suite of econometric forecasting models …

Neighborhood Light At Night And Noise Levels, And Long-Term Sleep Trajectories In The Southern Community Cohort Study, Samuel H Nyarko, Qian Xiao

Journal Articles

While light at night (LAN) and noise levels have been linked to suboptimal sleep outcomes, little is known about the link between these factors and long-term suboptimal sleep trajectories. The current study examined the association of neighborhood LAN and nighttime noise with long-term sleep trajectories in a cohort of Black individuals and White individuals predominantly from low-income communities. We used data from the Southern Community Cohort Study (N = 28,759 Black individuals and 16,276 White individuals). Sleep duration was self-reported at baseline and after an average of five years of follow-up, based on which we constructed nine sleep trajectories: normal-normal …

Parallelized Quadtrees For Image Compression In Cuda And Mpi, Aidan Jones

Senior Honors Theses

Quadtrees are a data structure that lend themselves well to image compression due to their ability to recursively decompose 2-dimensional space. Image compression algorithms that use quadtrees should be simple to parallelize; however, current image compression algorithms that use quadtrees rarely use parallel algorithms. An existing program to compress images using quadtrees was upgraded to use GPU acceleration with CUDA but experienced an average slowdown by a factor of 18 to 42. Another parallelization attempt utilized MPI to process contiguous chunks of an image in parallel and experienced an average speedup by a factor of 1.5 to 3.7 compared to …

Social Determinants Of Rural Food Security: Findings From Michigan's Upper Peninsula, Hongmei Lu, Angie Carter

Michigan Tech Publications, Part 2

Rural food insecurity is understudied, although many rural-specific characteristics influence rural food security. We used a mixed-mode survey to investigate how economic conditions, food support measures, and geospatial patterns impact rural residents' food insecurity in the six-county region of Michigan's Western Upper Peninsula. Three nested ordinal logistic regressions identify that household income and costs significantly influence rural food insecurity probability. Lack of time is also a key factor in increasing food insecurity probability. The ability to drive oneself to access food offsets the negative impacts of living a far distance from retail food locations; yet, transportation remains a barrier to …

Trends Of Sediment Resuspension And Budget In Southern Lake Michigan Under Changing Wave Climate And Hydrodynamic Environment, Longhuan Zhu, Pengfei Xue, Guy Meadows, Chenfu Huang, Jianzhong Ge, Cary D. Troy, Chin H. Wu

Michigan Tech Publications, Part 2

Sediment suspension and transport driven by waves and currents play a significant role in both the ecological and physical environments of large lakes. Lake Michigan has faced a rapidly increasing water level associated with intensified wind waves in the past decade. To investigate the spatiotemporal characteristics of suspended sediment concentration (SSC) and associated coastal sediment budgets in southern Lake Michigan, a 30-year (1991–2020) hindcast was performed using a coupled wave-current-sediment model (SWAN-FVCOM-CSTMS). We found that in southern Lake Michigan, the basin-wide mean SSC increased, and the coastal sediment loss accelerated dramatically, corresponding with intensified waves, currents and lake water level …

Addressing The Opioid Crisis Through County-Widen Public Safety Agencies’ Post-Overdose Outreach Programs, Julia Keane

School of Professional Studies

The opioid epidemic not only kills thousands every year but sees thousands survive overdoses only to overdose again in a continuous cycle. Massachusetts is no stranger to this epidemic, with numbers and patterns mirroring national rates. Newer changes to the drug supply, with fentanyl becoming increasingly used, sold, and cut with other drugs., have been on the rise and impact current opioid overdoses rates. Preventative measures are needed to address this public safety and public health crisis, not only bettering the current rates but decreasing future ones. This paper will first look at the methodology and literature used to understand …

Neighborhood Disadvantage And Breast Cancer-Specific Survival In The Us, Neha Goel, Alexandra E Hernandez, Angela Mazul

2020-Current year OA Pubs

IMPORTANCE: Despite improvements in breast cancer screening, treatment, and survival, disparate breast cancer-specific survival outcomes persist, particularly in disadvantaged neighborhoods. Most of these disparities are attributed to disparities in individual, tumor, and treatment characteristics. However, a critical knowledge gap exists as to whether disparities in breast cancer-specific survival remain after accounting for individual, tumor, and treatment characteristics.

OBJECTIVE: To evaluate if neighborhood disadvantage is associated with shorter breast cancer-specific survival after controlling for individual, tumor, and treatment characteristics in a national population.

DESIGN, SETTING, AND PARTICIPANTS: This national retrospective cohort study included patients with breast cancer diagnosed from 2013 to …

Climate Change-Associated Declines In Water Clarity Impair Feeding By Common Loons, Walter H. Piper, Max R. Glines, Kevin C. Rose

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

Climate change has myriad impacts on ecosystems, but the mechanisms by which it affects individual species can be difficult to pinpoint. One strategy to discover such mechanisms is to identify a specific ecological factor related to survival or reproduction and determine how that factor is affected by climate. Here we used Landsat imagery to calculate water clarity for 127 lakes in northern Wisconsin from 1995 to 2021 and thus investigate the effect of clarity on the body condition of an aquatic visual predator, the common loon (Gavia immer). In addition, we examined rainfall and temperature as potential predictors …

Making Sense Of Ethnocentrism: Intelligence Analysis & National Cultural Dimensions, Travis J. Benson

Doctoral Dissertations and Projects

Varying internal and external stimulants naturally oscillate the creation of objective intelligence analysis; however, the most egregious offender to accuracy and completeness is the natural human mental process. No element of intelligence analysis is more formidable than the cognitive process that houses specific deviations, known as biases, as it yields inaccuracies and alters what is believed to be a rational response to a complex analytical problem. The phenomenon of ethnocentrism is consistently identified as an analytical limitation of intelligence professionals, derived from cognitive bias. Ultimately, ethnocentrism manifests an analyst’s perception of information directly through the lens of culturally dependent heuristics …

Sanitation In Urban Areas May Limit The Spread Of Antimicrobial Resistance Via Flies, Drew Capone, Oliver Cumming, Abeoseh Flemister, Victor Ilevbare, Seth R. Irish, Ishi Keenum, Jackie Knee, Rassul Nala, Joe Brown

Michigan Tech Publications, Part 2

Synanthropic filth flies are common where sanitation is poor and fecal wastes are accessible to them. These flies have been proposed as mechanical vectors for the localized transport of fecal microbes including antimicrobial resistant (AMR) organisms and associated antimicrobial resistance genes (ARGs), increasing exposure risks. We evaluated whether an onsite sanitation intervention in Maputo, Mozambique reduced the concentration of enteric bacteria and the frequency of detection of ARGs carried by flies collected in household compounds of low-income neighborhoods. Additionally, we assessed the phenotypic resistance profile of Enterobacteriaceae isolates recovered from flies during the pre-intervention phase. After fly enumeration at study …

Prendersi Cura: Taking Care Of Nature In Perugia, Italy, Katharine Kurtz

Other student scholarship

Cities need more green spaces to adapt to climate change and facilitate community resilience. However, successfully managing green spaces is challenging. City governments consistently employ top-down management practices that limit the benefits, usage, and perception of such spaces as Nature. Further, current management practices overlook socio-cultural factors important to residents. Using the existing categories of urban green spaces (UGS) and informal green spaces (IGS), this article situates the cultural practice prendersi cura as a way to conceptualize successful, bottom-up green space management. The term prendersi cura, meaning “to take care of” in Italian, emerged through interviews in Perugia, Italy, and …
