The Impact Of Pre-Experiment Walking On Distance Perception In Vr, Soheil Sepahyar

Dissertations, Master's Theses and Master's Reports

While individuals can accurately estimate distances in the real world, this ability is often diminished in virtual reality (VR) simulations, hampering performance across training, entertainment, prototyping, and education domains. To assess distance judgments, the direct blind walking method—having participants walk blindfolded to targets—is frequently used. Typically, direct blind walking measurements are performed after an initial practice phase, where people become comfortable with walking while blindfolded. Surprisingly, little research has explored how such pre-experiment walking impacts subsequent VR distance judgments. Our initial investigation revealed increased pre-experiment blind walking reduced distance underestimations, underscoring the importance of detailing these preparatory procedures in research—details …

Supporting Team Innovation With Design Thinking Cognitive Strategies, Lisa M. Casper

Dissertations, Master's Theses and Master's Reports

Innovation is a 21st-century skill needed to design new systems, solve challenging problems, and develop novel solutions. Design Thinking (DT) is a tool used to support team innovation. In this experiment, 145 students (47 teams) used one of two DT methods during a semester-long project to come up with an innovative solution to one of the UNESCO 17 sustainable development goals. The key experimental manipulation was during the DT Ideate phase where teams brainstormed potential solutions. Teams either used a baseline DT Ideate strategy or an expanded one with additional prompts during a 10-minute period. Results indicated that teams using …

Feeding Our Local Communities-The Benefits Of Food Assistance Programs At Local Farmers Markets, Courtney A. Archambeau

Dissertations, Master's Theses and Master's Reports

Living in a rural area can make finding food that is good and affordable difficult, especially for those who rely on assistance from the Supplemental Nutrition Assistance Program or SNAP. Federal incentive programs assist those with SNAP benefits to purchase fresh produce. I studied three farmers markets in Houghton County in Michigan’s western Upper Peninsula to identify how rural farmers markets are integrating these programs to increase access to fresh produce. Specifically, I asked: 1) How might farmers markets work to be more inviting and make their food more accessible to those of lower socioeconomic status?; 2) By studying these …

Structural Analysis And Interpretation Of Deformation Along The Keweenaw Fault System From Lake Linden To Mohawk, Michigan, Nolan G. Gamet

Dissertations, Master's Theses and Master's Reports

The Keweenaw fault is likely the most significant and most studied fault associated with the Midcontinent Rift System. The fault roughly bisects the Keweenaw Peninsula and places Portage Lake Volcanics (~1.1 Ga) over much younger Jacobsville Sandstone (~1.0 Ga). Published bedrock geology maps with cross sections from the 1950s show the fault as a single continuous trace that is locally associated with smaller cross faults and splays. The accompanying cross-sections show hanging-wall volcanic strata having a well-defined, listric geometry with dip decreasing away from the fault to the northwest.

This M.S. thesis presents a structural analysis and interpretation of the …

The Rhetorical Art Of Risk Assessment: Lessons From Risk Management In Rural And Tribal Communities, John L. Velat

Dissertations, Master's Theses and Master's Reports

Risk assessment, mitigation, and communication rely on data from multiple sources to form a complete understanding of hazards and how to manage them. Experts can use these data to make informed decisions about the nature and extent of risks and inform the public to protect health, the environment, and economic welfare. However, in an effort to objectively make decisions, technical experts and policymakers increasingly rely on quantitative data as the most important determiner of risk, which can alienate the public, limit risk understanding, and delay or miss obvious signals of impending catastrophe. I examine several cases based on my experiences …

Structural Analysis And Slip Kinematics Of The Keweenaw Fault System Between Bête Grise Bay And Gratiot Lake, Keweenaw County, Michigan, Daniel J. Lizzadro-Mcpherson

Dissertations, Master's Theses and Master's Reports

The Keweenaw fault is perhaps the most significant geologic structure on the Keweenaw Peninsula, with an estimated 7-11 km of reverse slip juxtaposing volcanic strata of the ~1.1 Ga Portage Lake Volcanics above ~1.0 Ga Jacobsville Sandstone. The fault has been interpreted as a rift-bounding normal fault later inverted by compressional pulses of the Grenville Orogeny or, more recently, as part of a detached thrust fault system unrelated to an earlier normal fault. The fault is shown on published maps as a single continuous fault trace whose sinuosity implies multiple fault segments and complex slip dynamics. Mapping along Bête Grise …

Accepting Change: Facets Of Acceptance & Sustainable Redevelopment, Zoe L. Ketola

Dissertations, Master's Theses and Master's Reports

As the effects of climate change worsen, it becomes increasingly apparent that just development efforts must be rooted in principles of sustainability and community engagement. This research addresses the role that acceptance plays within two different examples of sustainable redevelopment. The first empirical case examines acceptance of genetically improved trees among family forest owners. The second case explores policy acceptance of community-centric redevelopment of brownfield sites for renewable energy generation. This work uses a combination of survey data and document analysis to shed light on two specific forms of sustainable redevelopment and the consideration given to community priorities and acceptance …

Using Artificial Intelligence To Understand Environmental Policy Innovation Labs' Contribution To The Sustainable Development Goals, Sidney M. Mechling

Dissertations, Master's Theses and Master's Reports

Policy innovation labs (PILs) serve as centers of experimental innovation pursued by governmental, private, and non-profit entities that employ design-thinking methodology, scientific experimentation, and user-centric approaches (Wellstead et al., 2021). The multi-disciplinary expertise of policy innovation labs in social and economic topics equips them to offer policy recommendations addressing public issues, including environmental concerns. When designing innovative solutions, it is customary for policy innovation labs to provide substantial information and reports detailing their progress and methods. However, the wealth of information available becomes a challenge to fully divest in comprehending a lab's contribution to solving global issues. This report addresses …

Altering The Environment: The Effects Of Light And Music On Vigilance Performance And Affective State, Lauren Sprague

Dissertations, Master's Theses and Master's Reports

Vigilance, otherwise known as a state of alert watchfulness, is a phenomenon that occurs when someone is sustaining their attention on a particular task or environment. Largely, tasks that require a state of vigilance induce negative mood outcomes, result in loss of performance over time, and cause increased disengagement from the task. These tasks involve detecting critical signals which are buried among more frequently occurring neutral signals. While little can be done to change the base nature of the vigilance task, altering the physical environment of the operator may improve working conditions to a point where there are fewer losses …

Investigating Collaborative Explainable Ai (Cxai)/Social Forum As An Explainable Ai (Xai) Method In Autonomous Driving (Ad), Tauseef Ibne Mamun

Dissertations, Master's Theses and Master's Reports

Explainable AI (XAI) systems primarily focus on algorithms, integrating additional information into AI decisions and classifications to enhance user or developer comprehension of the system's behavior. These systems often incorporate untested concepts of explainability, lacking grounding in the cognitive and educational psychology literature (S. T. Mueller et al., 2021). Consequently, their effectiveness may be limited, as they may address problems that real users don't encounter or provide information that users do not seek.

In contrast, an alternative approach called Collaborative XAI (CXAI), as proposed by S. Mueller et al (2021), emphasizes generating explanations without relying solely on algorithms. CXAI centers …

Explicit Rule Learning: A Cognitive Tutorial Method To Train Users Of Artificial Intelligence/Machine Learning Systems, Anne Linja

Dissertations, Master's Theses and Master's Reports

Today’s intelligent software systems, such as Artificial Intelligence/Machine Learning systems, are sophisticated, complicated, sometimes complex systems. In order to effectively interact with these systems, novice users need to have a certain level of understanding. An awareness of a system’s underlying principles, rationale, logic, and goals can enhance the synergistic human-machine interaction. It also benefits the user to know when they can trust the systems’ output, and to discern boundary conditions that might change the output. The purpose of this research is to empirically test the viability of a Cognitive Tutorial approach, called Explicit Rule Learning. Several approaches have been used …

The Hidden Role Of The “Co-” Paradigm In The Conceptualization And Application Of Living Labs, Madelina E. Dilisi

Dissertations, Master's Theses and Master's Reports

In the past two decades, the living lab has emerged as an innovative approach for addressing a wide range of issues. Living labs challenge traditional top-down research and development approaches in an array of subjects including climate change and sustainability, healthcare, information communication technology, and urban planning. Despite their growth, the current conceptualization of living labs is incomplete. The conceptual ambiguity surrounding living labs prevents researchers and practitioners from appreciating their true value, limitations, and appropriate applications. My thesis builds on Dekker et al.’s (2020) living lab research by including key concepts from the “co” paradigm literature that includes the …

This report examines the practice of carbon offset programs on private nonindustrial forestlands in the state of Michigan ass. Previously, the state of Michigan provided technical assistance for enrollment in carbon offsets through the Michigan Working Forest Carbon Offset Program, but this program has now been discontinued. Currently, private companies and nongovernmental organizations are developing projects throughout the state with nonindustrial private landowners. This descriptive analysis in this case study examines the roles of different forest practitioners who are working on carbon offsets, including private consulting foresters and foresters within Michigan public agencies. I review the academic and grey literature …

Information Use And Decision-Making For Evacuation At Fuego Volcano, Guatemala, Beth A. Bartel

Dissertations, Master's Theses and Master's Reports

For populations living with risk to rapid-onset environmental hazards, an effective early warning system (EWS) may be the most viable short- to mid-term solution for risk reduction. At Fuego volcano, Guatemala, more than 60,000 people distributed between more than 30 small communities live within the identified hazard zones for pyroclastic density currents (PDCS), highly lethal hot avalanches and surges of volcanic gases, rock, and ash. Despite ongoing risk reduction efforts by scientific and civil protection authorities, more than 400 people died during a paroxysmal eruption on 3 June 2018 when PDCs reached populated areas. A high-end resort, La Reunión, evacuated …

Types Of Questions Teachers Ask To Engage Students In Making Sense Of A Student Contribution, Nishat B. Alam

Dissertations, Master's Theses and Master's Reports

In the student-centered classroom, a teacher’s interpretation and response to student mathematical contributions plays an important role to shape and direct students’ opportunities for sense-making. This research used a scenario-based survey questionnaire to examine what types of questions middle and high school mathematics teachers indicate they would ask to engage students in making sense of a high-leverage student mathematical contribution and their reasoning about why particular questions are or are not productive. From the results, it could be concluded that teachers asked more productive questions after seeing a set of possible questions. Their beliefs about the productivity of the questions …
