Constructing Engineering Knowledge Through Tinkering, Reflection, And Digital Storytelling, Lauren C. Pagano

Dissertations

Educators and researchers suggest that informal learning activities in museums, libraries, and families’ homes can promote children’s science, technology, engineering, and mathematics (STEM) learning (Sobel & Jipson, 2016). Tinkering, a form of hands-on problem-solving involving real tools and materials, is one way to engage families in engineering design processes. However, tinkering activities vary greatly in terms of the goals presented, the resources available, and opportunities to test (Bevan, 2017). Across three studies, we examined how variations in tinkering exhibit design and parent-child interaction relate to children’s memory and STEM learning. In Study 1, we examined the structure and content of …

Leveraging Moral Foundations To Increase Covid-19 Vaccination, Cara Elizabeth Ray

Dissertations

Despite the vast majority of the eligible U.S. adult population being vaccinated against COVID-19, geographical clusters of unvaccinated individuals pose a substantial risk of outbreak. It is important to encourage as many individuals as possible to vaccinate against COVID-19 to reduce its spread and severity. Past research has identified endorsement of the purity and liberty moral foundations – intuitive domains of moral concern – as predictors of vaccine hesitancy and political conservatism, while conservatism is itself associated with vaccine hesitancy. Across two online surveys, I examined the effects of a message invoking the purity and liberty foundations as well as …

It Doesn’T Get Better With Time: The Effect Of Housing Insecurity On Rearrest In Polk And Palm Beach County, Quintin Williams

Dissertations

Housing insecurity is one of the main drivers of poverty and inequality in contemporary urban society. We know that this insecurity contributes to poor outcomes for the individuals experiencing it. We know less about how this housing insecurity impacts contact with the criminal justice system. Using event history analysis, this study assesses the effects of housing insecurity in Polk County Iowa and Palm Beach County Florida. Results confirm that housing insecurity increases the risk of being rearrested each day a person is without stable housing. These findings reveal that lack of access to safe, affordable, and stable housing not only …

School of Environmental Sustainability: Faculty Publications and Other Works

In recent years, pollution of watercourses in nearby protected ecosystems has increased due to urbanization. Standard physiochemical methods and probes are one way to monitor watercourses for quality. However, they often do not provide the full ecological status of the body of water. In this work, we set out to assess the ecological water quality of an urban stream by using benthic macroinvertebrates as bioindicators. We conducted the work on the Orienco stream in Lago Agrio in the province of Sucumbíos in the Northern Ecuadorian Amazon (NEA). The stream has become a sink of raw domestic sanitary wastewater from rural …

Objective: The purpose of this article is to highlight the value of Black fathers to the sexual decision-making processes among Black adolescent and young adult daughters. Background: Various contextual factors, such as fewer sexual health resources in poorer communities and federal funding cuts to family planning service agencies, ultimately contribute to the sexual health decision-making of adolescent young women and may be linked to sexual health disparities among Black adolescent women. Recent studies have reported the protective nature of a Black father’s engagement to be beneficial to the behavioral outcomes of adolescent daughters. Method: Findings from 17 semistructured interviews conducted …

Strategies To Mitigate The Effects Of Negative Political Rhetoric On Service Providers: A Study In Two Refugee-Serving Organizations, Maria V. Wathen, Charity N. Weishar, Patrick L.F. Decker

Social Work: School of Social Work Faculty Publications and Other Works

This paper explores the strategies that staff at two refugee-serving organizations found helpful in mitigating their increased distress from negative political rhetoric aimed at their clients. Results point to the importance of organizational acknowledgement of the distress. Additionally, staff perceived that intentionally focused organizational interventions can mitigate the emotional impacts of negative rhetoric. Finally, strategies employees used to lessen their distress and regain a sense of efficacy included recommitment to the mission, advocacy for refugees among family and friends, strong reliance on religious faith in coping, and an avoidance of the rhetoric by decreasing engagement with news and social media.

Casting And Splinting Options For Pseudo-Jones Avulsion Fractures: An Evidence-To-Practice Review, Amber M. Kingsley, Aysha B. Reyes, Zachary K. Winkelmann

Clinical Practice in Athletic Training

Avulsion fractures of the fifth metatarsal bone occur when a portion of the bone is broken or pulled off the rest of the bone. These fractures are often seen in athletes, especially those of a young age. Avulsion fractures of the fifth metatarsal bone are commonly treated non-surgically with immobilization of the foot. There are several different options for immobilization of the foot with no clear result as to which immobilization method is the most effective. The purpose of this evidence-to-practice review was to summarize a systematic review on comparative outcomes of immobilization interventions on avulsion fractures of the fifth …

Cook Like A Boss Online: An Adapted Intervention During The Covid-19 Pandemic That Effectively Improved Children’S Perceived Cooking Competence, Movement Competence And Wellbeing, Lynsey Hollywood, Johann Issartel, David Gaul, Amanda Mccloat, Elaine Mooney, Clare Elizabeth Collins, Fiona Lavelle

Articles

The COVID-19 pandemic has further exacerbated physical inactivity, poor dietary intake and reduced mental wellbeing, contributing factors to non-communicable diseases in children. Cooking interventions are proposed as having a positive influence on children’s diet quality. Motor skills have been highlighted as essential for performance of cooking skills, and this movement may contribute to wellbeing. Additionally, perceived competence is a motivator for behaviour performance and thus important for understanding intervention effectiveness. Therefore, this research aimed to assess the effectiveness of an adapted virtual theory-based cooking intervention on perceived cooking competence, perceived movement competence and wellbeing.

The Application Of Salutogenesis In Communities And Neighborhoods, Lenneke Vaandrager, Lynne Kennedy

All Works

Communities and neighborhoods have reemerged as important settings for health promotion; they are particularly effective for encouraging social processes which may shape our life-chances and lead to improved health and well-being; consequently, as Scriven and Hodgins, (2012) note, of all the settings (cities, schools, workplaces, universities, etc.), communities are the least well defined. Indeed, within the health literature, they are frequently referred to in terms of place, identity, social entity, or collective action.This chapter on communities and neighborhoods distinguishes between settings as a place (natural and built environment), identity (sense of community), social entity (cohesion, social capital), and collective action …

Fatigue In Aircraft Maintenance Technician Schools, Natalie Zimmermann, Peng Hao Wang, Keegan Pullen

International Journal of Aviation, Aeronautics, and Aerospace

Fatigue has long been identified as a human factor in aviation. Subsequently, a series of studies have highlighted fatigue-related elements within the context of the aviation industry, focusing on the flight deck – with some extension to flight students – and aviation maintenance activities. However, the latter has not been as deeply examined as its flight crew-centered counterpart. Similarly – if not more significantly – fatigue experienced by aircraft maintenance technician (AMT) students is scarcely explored, especially in comparison to the research conducted to understand fatigue in flight schools. AMT students are subject to comparable, but not the same, experiences …

International Journal of Aviation, Aeronautics, and Aerospace

Comfort is an important factor for passengers in the selection of airlines, and electric propeller aircraft will be an important element of future sustainable aviation. In this paper, we studied the order of importance of different (dis)comfort factors regarding traveling with propeller aircraft. Two experiments were conducted, one was a simulation flight on the ground with 33 participants and the other were two real flights with 97 participants. All participants were asked to rank the importance of different (dis)comfort factors in different phases of flights. Results indicated that though there are differences between the simulation and the real flights, noise, …

The Persistence Of Safety Silence: How Flight Deck Microcultures Influence The Efficacy Of Crew Resource Management, Kimberly Perkins, Sourojit Ghosh, Julie Vera, Cecilia Aragon, Adam Hyland

International Journal of Aviation, Aeronautics, and Aerospace

The majority of First Officers and Captains feel that Captains establish the tone of the flight deck microculture. However, the majority of these pilots also report that as First Officers, they have hesitated to share safety-pertinent data and/or experience being silenced after sharing safety data due to a psychologically unsafe flight deck. Utilizing direct feedback from industry pilots, we explore ways that Captains can create a more inclusive microculture that elicits safety voice. The safety system designed to enhance crew collaboration, Crew Resource Management, fails to adequately establish tools for designing a psychologically safe flight deck. We conclude that Crew …

International Journal of Aviation, Aeronautics, and Aerospace

Objective

This research investigates and compares working-conditions, duty rosters, stress, sleep problems, fatigue levels, mental health, and well-being of pilots working for network (NWCs), and low-cost carriers (LCCs). This study extends previous research by investigating working conditions, pilots’ actual rosters, fatigue and mental health of two groups of pilots flying for LCC or NWC.

Method

A comprehensive cross-sectional online survey was completed by N=338 pilots (185 NWC, 153 LCC pilots). All pilots reported their roster data of the last 2 months during peak flight season, psychosocial and work-related stress (e.g., high job insecurity, less total flight-experience, lower income, more time …

Exploring Algorithmic Literacy For College Students: An Educator’S Roadmap, Susan Gardner Archambault

LMU Theses and Dissertations

Research shows that college students are largely unaware of the impact of algorithms on their everyday lives. Also, most university students are not being taught about algorithms as part of the regular curriculum. This exploratory, qualitative study aimed to explore subject-matter experts’ insights and perceptions of the knowledge components, coping behaviors, and pedagogical considerations to aid faculty in teaching algorithmic literacy to college students. Eleven individual, semi-structured interviews and one focus group were conducted with scholars and teachers of critical algorithm studies and related fields. Findings suggested three sets of knowledge components that would contribute to students’ algorithmic literacy: general …

Dynamic Modeling Of Inland Flooding And Storm Surge On Coastal Cities Under Climate Change Scenarios: Transportation Infrastructure Impacts In Norfolk, Virginia Usa As A Case Study, Yawen Shen, Navid Tahvildari, Mohamed M. Morsy, Chris Huxley, T. Donna Chen, Jonathan Lee Goodall

Civil & Environmental Engineering Faculty Publications

Low-lying coastal cities across the world are vulnerable to the combined impact of rainfall and storm tide. However, existing approaches lack the ability to model the combined effect of these flood mechanisms, especially under climate change and sea level rise (SLR). Thus, to increase flood resilience of coastal cities, modeling techniques to improve the understanding and prediction of the combined effect of these flood hazards are critical. To address this need, this study presents a modeling system for assessing the combined flood impact on coastal cities under selected future climate scenarios that leverages ocean modeling with land surface modeling capable …

Civil & Environmental Engineering Faculty Publications

Bike-sharing holds promise for available and healthy mobility services during COVID-19 where bike sharing users can make trips with lower health concerns due to social distancing compared to the restricted transportation modes such as public transit and ridesharing services. Leveraging the trip data of the Divvy bike-sharing system in Chicago, this study explores spatially heterogeneous effects of built environment on bike-sharing usage under the pandemic. Results show that the average weekly ridership declined by 52.04%. To account for the spatially heterogeneous relationship between the built environment and the ridership, the geographically weighted regression (GWR) model and the semiparametric GWR (S-GWR) …

Detection Of Overlapping Passive Manipulation Techniques In Image Forensics, Gianna S. Lint, Umit Karabiyik

Annual ADFSL Conference on Digital Forensics, Security and Law

With a growing number of images uploaded daily to social media sites, it is essential to understand if an image can be used to trace its origin. Forensic investigations are focusing on analyzing images that are uploaded to social media sites resulting in an emphasis on building and validating tools. There has been a strong focus on understanding active manipulation or tampering techniques and building tools for analysis. However, research on manipulation is often studied in a vacuum, involving only one technique at a time. Additionally, less focus has been placed on passive manipulation, which can occur by simply uploading …

A Risk-Averse Mechanism For Suicidality Assessment On Social Media, Ramit Sawhney, Atula Tejaswi Neerkaje, Manas Gaur

Publications

Recent studies have shown that social media has increasingly become a platform for users to express suicidal thoughts outside traditional clinical settings. With advances in Natural Language Processing strategies, it is now possible to design automated systems to assess suicide risk. However, such systems may generate uncertain predictions, leading to severe consequences. We hence reformulate suicide risk assessment as a selective prioritized prediction problem over the Columbia Suicide Severity Risk Scale (C-SSRS). We propose SASI, a risk-averse and self-aware transformer-based hierarchical attention classifier, augmented to refrain from making uncertain predictions. We show that SASI is able to refrain from 83% …

Arithfusion: An Arithmetic Deep Model For Temporal Remote Sensing Image Fusion, Md Reshad Ul Hoque, Jian Wu, Chiman Kwan, Krzysztof Koperski, Jiang Li

Electrical & Computer Engineering Faculty Publications

Different satellite images may consist of variable numbers of channels which have different resolutions, and each satellite has a unique revisit period. For example, the Landsat-8 satellite images have 30 m resolution in their multispectral channels, the Sentinel-2 satellite images have 10 m resolution in the pan-sharp channel, and the National Agriculture Imagery Program (NAIP) aerial images have 1 m resolution. In this study, we propose a simple yet effective arithmetic deep model for multimodal temporal remote sensing image fusion. The proposed model takes both low- and high-resolution remote sensing images at t₁ together with low-resolution images at a …

Reskilled And Integrated, But How? Navigating Trauma And Temporary Hardships, Cihan Aaydiner, Erin L. Rider

Research, Publications & Creative Work

Immigrants are often pressed to show how they will contribute to a host country, thus proving through their conditions of entry and human capital whether they will be perceived as an asset or burden, and this is juxtaposed with the host country’s institutions offering an improved quality of life, mainly through employment. Seeking employment is often a key factor to be economically assimilated, and in the case of highly educated Turkish migrants, the opportunity to reclaim their previous professional and quality of life statuses. Based on qualitative research, we have examined the experiences of highly educated Turkish people (n = …

Abolition Is Not Abstract: Zines And The Transmission Of Revolutionary Cultural Capital, Austin Wonder

Master's Theses

Abolition as a theory and practice-whether in relation to the institution of the prison, systems of policing, or the carceral state as a whole-has received relatively little attention or serious appreciation within the discipline of Sociology. Calls for the abolition of policing and prisons are often taken for granted as naïve and radical demands, perceived as being disassociated from the material conditions of reality. Nonetheless, abolitionist analyses provide a unique and critical perspective from which to explore alternatives to addressing pervasive police violence and mass incarceration through strategies which do not rely upon, or increase the power of, the criminal …

Growth Of Condition-Related Knowledge Among Youth With Spina Bifida: Associations With Neurocognitive Functioning And Self-Management Skills, Olivia Emery Clark

Master's Theses

Spina bifida (SB) is a congenital birth defect that may involve physical, medical, and neuropsychological complications due to central nervous system malformation (Copp et al., 2015). Ambulation problems, bladder and bowel dysfunction, and hydrocephalus require daily medical management tasks, including catheterization, bowel program management, and skin checks to avoid secondary complications. While self-management skills are typically gained during adolescence, executive dysfunction in SB may complicate gains (Dennis et al., 2006; Greenley, 2010). Indeed, evidence in other chronic conditions suggests that adolescent executive dysfunction is linked to poorer medical self-management. Condition-related knowledge has been identified as an important basis of medical …

The Effect Of Group Identification And Emotion On Participation In Collective Action, Iryna Chaban

Master's Theses

In the last few years, the number of collective actions in the United States started to increase. These events have been ranging from peaceful to violent. The present research aims to understand what is causing groups to participate in collective action and become aggressive. It will expand understanding of group identification, emotion, and participation in collective action. The researcher hypothesizes that individuals who hold higher identification with a group are more likely to experience anger and participate in a protest. Data collection involved an online survey. Introductory psychology students read a passage describing a protest and respond to several short …

A Study In The Effectivenss Of Factual Versus Emotional Interventions In Reducing Ambivalent Sexism In Hiring Decisions, Molly Jane Driscoll

Master's Theses

Ambivalent sexism – divided into the categories of benevolent sexism (BS) and hostile sexism (HS) – is imbedded in many parts of the workplace. This study aims to explore if ambivalent sexism influences hiring decisions and, if so, what can be done about it. After completing a series of surveys, participants were asked to read about an agentic female candidate who applied for a male-dominated position. Afterwards, participants went through either a factual or emotional intervention before reevaluating their decision. Major results showed that only the emotional intervention increased the likelihood of the candidate being hired but it is not …

Examining The Bidirectional Relations Between Psychological Functioning And Academic Outcomes Among College Students, Maya Hareli

Master's Theses

Emerging adulthood is a developmental period associated with a variety of transitions and changes, including rising rates of mental health concerns (Arnett, 2004, 2006; Center for Collegiate Mental Health, 2020). The literature has established that both psychological and academic functioning are critical components of students’ lives, as mental health has been shown to interfere with students’ grades, graduation rates, and postgraduate employment (Hartley, 2010; Mojtabai et al., 2015), while poor achievement is associated with mental health challenges in college and beyond (Bruffaerts et al., 2018; Respondek et al., 2017). Additionally, women and men have been shown to experience these areas …
