Noise And Time Pressure Effects On Situation Awareness And Aviation Maintenance Tasks, Syaza R. M. Haris

Doctoral Dissertations and Master's Theses

Aircraft maintenance technicians (AMTs) working in a line maintenance work setting are very susceptible to the deafening occupational noise from the airport vicinity or the maintenance machinery itself. Compared to a base maintenance working period, a line maintenance job requires AMTs to complete a task within a short time frame. The current study's objective is to determine if different noise levels and time pressure influence AMTs' performance and situation awareness (SA). Sixteen Embry-Riddle Aeronautical University students majoring in Aviation Maintenance Science participated in a within-subject experimental design. Each participant's performance, SA level, and perceived workload were measured during maintenance tasks …

Nature-Based Solutions In Environmental Planning: Ecosystem-Based Adaptations, Green Infrastructures, And Ecosystem Services To Promote Diversity In Urban Landscapes, Lorena Alves Carvalho Nascimento

Dissertations and Theses

Nature-based solutions encompass strategies that explore ecosystem-based adaptations, green infrastructures, and ecosystem services in environmental planning and landscape management. However, nature-based solutions do not always consider ecological values and perspectives from Black, Indigenous, and Global South population. This dissertation has three independent papers that explore the application of ecosystem-based adaptations, green infrastructures, and ecosystem services in communities unheard by environmental planning agencies. The first paper is a conceptual framework that used literature review and observations of current human-nature interactions to reflect how the criminalization, acculturation, and cultural appropriation of cultural ecosystem services have burdened Black and Indigenous identities. Recommendations for …

Antipsychotic Medication Administration In Oregon Assisted Living/Residential Care Settings: Analyzing An Action Situation, Sarah Dys

Dissertations and Theses

Antipsychotic medication use (APU) in assisted living and residential care (AL/RC) settings is an under-studied and controversial health policy issue. APU in older adults with dementia is associated with an increased risk of falls, hospitalizations, and early mortality. I operationalize the Institutional Analysis and Development Framework using a situational analysis approach, an extension of grounded theory methods, to explore the APU in Oregon AL/RC settings. Regulatory deficiency citations, Oregon AL/RC population data, and semi-structured interviews suggest that staff role clarity, organizational characteristics, and perceived agency influence decision-making around APU. AL/RC providers and caregivers are forced to simultaneously balance and prioritize …

Found in the water column, sediment, shorelines, estuaries, freshwater streams and rivers along with terrestrial soils, flora and fauna. The continuous input of plastic waste into the marine environment doesn't seem to be slowing as the amount of plastic created each year increases globally.

This study investigated (1) the effects of microplastic ingestion in the indicator species, the Pacific mole crab (Emerita analoga), testing the predator avoidance behavior, reproductive output and parasitism effects when an adult female gravid crab had ingested microplastics (2) adult mortality, hatching …

A New Criterion For Fluoroquinolone-Associated Disability Diagnosis: Functional Gastrointestinal Disorders, Deanna N. Cannizzaro, Lydia F. Naughton, Maya Z. Freeman, Linda Martin, Charles L. Bennett M.D., Ph.D., Cecilia Bove

Faculty Publications

Background and Objectives: Fluoroquinolones (FQs) are a broad-spectrum class of antibiotics routinely prescribed for common bacterial infections despite recent recommendations to use them only for life-threatening cases. In addition to their antimicrobial properties, FQs act in the central nervous system as GABAA receptor inhibitors, which could potentially affect functionality of the vagus nerve at the forefront of gastrointestinal (GI) tract function. Alterations in neural control of digestion have been shown to be linked to Functional Gastrointestinal Disorders (FGIDs), which are usually diagnosed based on self-reported symptoms. The aim of this study was to assess the incidence of FGIDs following FQ …

Robotic Olfactory-Based Navigation With Mobile Robots, Lingxiao Wang

Doctoral Dissertations and Master's Theses

Robotic odor source localization (OSL) is a technology that enables mobile robots or autonomous vehicles to find an odor source in unknown environments. It has been viewed as challenging due to the turbulent nature of airflows and the resulting odor plume characteristics. The key to correctly finding an odor source is designing an effective olfactory-based navigation algorithm, which guides the robot to detect emitted odor plumes as cues in finding the source. This dissertation proposes three kinds of olfactory-based navigation methods to improve search efficiency while maintaining a low computational cost, incorporating different machine learning and artificial intelligence methods.

IGC Proceedings (1977-2023)

The objective of this study was to establish an intensive grazing system of meadow fescue (Festuca elatior L.) pasture for high-producing dairy cows in some areas of Japan where soil freezes in winter. Plant succession of meadow fescue pastures that had been grazed at different plant heights and milk production from cows grazed on meadow fescue pasture compared to that from cows grazed on perennial ryegrass pasture were surveyed over a five year period. Succession of meadow fescue pasture depended on the management of plant height before grazing use. Milk production from cows grazed on meadow fescue pasture was …

Leaf Blade Selection By Sheep In Kleingrass (Panicum Coloratum L.) Pastures With Different Deferment Periods, P. Sierra, M. S. Cid, M. A. Brizuela, C. M. Ferri

IGC Proceedings (1977-2023)

The winter use of standing dead biomass produced by warm season grasses during the previous growing season may be an alternative to grazing systems in the semi-arid Pampean Region of Argentina. This study evaluated: 1) the effect of different deferment periods on the leaf blade percentage and quality of ‘kleingrass’ (Panicum coloratum L.), a warm season specie recently introduced to that region, and 2) whether rams grazing the vegetation accumulated during these different periods are able to select leaf blades to maintain the quality of their diets. It was generated three treatments by deferment of the forage produced after …

Microhistological Estimation Of Leaf Blade Percentage In Diets From Monoespecific Pastures, P. Sierra, M. S. Cid, M. A. Brizuela, C. M. Ferri

IGC Proceedings (1977-2023)

Although a decrease in the leaf-stem ratio affects the nutritive value of pastures, herbivores can reinforce selection for leaf blades to maintain the quality of their diets. This study evaluated whether the percentage of fragments with furrows in blades could be used to estimate the relative intake of this part of the leaves by herbivores grazing monoespecific pastures. It was worked with vegetation of kleingrass (Panicum coloratum L.) from paddocks with three deferment periods. Blade samples, and different plant part mixtures hand compounded were in vitro digested. The digestion residues were microhistological analyzed determining the number of fragment with …

Evaluation Of Kentucky Bluegrass (Poa Pratensis L.) For Creating Sustainable Grazing Swards In Hokkaido, T. Saigusa, S. Tejima, Y. Ogawa, S. Takahashi

IGC Proceedings (1977-2023)

Kentucky bluegrass (Poa pratensis L.) is generally considered to be a weed in the meadows of Hokkaido. However, a revaluation of this species should be undertaken in terms of its useful characteristics for labor-saving management on farms in marginal areas. The performance of steers (Holstein-Friesian) and botanical composition of Kentucky bluegrass swards were investigated under the stocking methods of set and rotational grazing and compared with timothy (Phleum pratense L.) swards. Kentucky bluegrass was stable over the grazing season under both methods, although timothy decreased rapidly. The average daily gain of steers raised on Kentucky bluegrass swards was …

The Pow+Tree Strategy’S Effects On The Argumentative Writing Of Struggling Secondary Students, Matthias Grünke

Journal of Educational Research and Practice

The present study aims to evaluate the effects of an argumentative writing strategy (POW+TREE) on four struggling ninth graders’ ability to produce persuasive texts regarding their point of view on different questions.
