Harnessing The Power Of Interdisciplinary Research With Psychology-Informed Cyberbullying Detection Models, Deborah Hall, Yasin N. Silva, Brittany Wheeler, Lu Cheng, Katie Baumel

Computer Science: Faculty Publications and Other Works

Cyberbullying has become increasingly prevalent, particularly on social media. There has also been a steady rise in cyberbullying research across a range of disciplines. Much of the empirical work from computer science has focused on developing machine learning models for cyberbullying detection. Whereas machine learning cyberbullying detection models can be improved by drawing on psychological theories and perspectives, there is also tremendous potential for machine learning models to contribute to a better understanding of psychological aspects of cyberbullying. In this paper, we discuss how machine learning models can yield novel insights about the nature and defining characteristics of cyberbullying and …

Background Cutaneous T-cell lymphoma (CTCL) patients often suffer from recurrent skin infections and profound immune dysregulation in advanced disease. The gut microbiome has been recognized to influence cancers and cutaneous conditions; however, it has not yet been studied in CTCL.ObjectivesTo investigate the gut microbiome in patients with CTCL and in healthy controls.MethodsA case-control study was conducted between January 2019 and November 2020 at Northwestern’s busy multidisciplinary CTCL clinic (Chicago, Illinois, USA) utilizing 16S ribosomal RNA gene amplicon sequencing and bioinformatics analyses to characterize the microbiota present in fecal samples of CTCL patients (n = 38) and age-matched healthy controls (n …

Runoff And Discharge Pathways Of Microplastics Into Freshwater Ecosystems: A Systematic Review And Meta-Analysis, J. Wang, K. Bucci, P. A. Helm, T. Hoellein, M. J. Hoffman, R. Rooney, C. M. Rochman

Biology: Faculty Publications and Other Works

Although many studies have focused on the importance of littering and (or) illegal dumping as a source of plastic pollution to freshwater, other relevant pathways should be considered, including wastewater, stormwater runoff, industrial effluent/runoff, and agricultural runoff. Here, we conducted a meta-analysis focused on these four pathways. We quantified the number of studies, amount and characteristics of microplastics reported, and the methods used to sample and measure microplastics from each pathway. Overall, we found 121 studies relevant to our criteria, published from 2014 to 2020. Of these, 54 (45%) quantified and characterized microplastics in discharge pathways. Although most focused on …

Microplastic Accumulation In Riverbed Sediment Via Hyporheic Exchange From Headwaters To Mainstems, Jennifer D. Drummond, Uwe Schneidewind, Angang Li, Timothy J. Hoellein, Stefan Krause, Aaron I. Packman

Biology: Faculty Publications and Other Works

In rivers, small and lightweight microplastics are transported downstream, but they are also found frequently in riverbed sediment, demonstrating long-term retention. To better understand microplastic dynamics in global rivers from headwaters to mainstems, we developed a model that includes hyporheic exchange processes, i.e., transport between surface water and riverbed sediment, where microplastic retention is facilitated. Our simulations indicate that the longest microplastic residence times occur in headwaters, the most abundant stream classification. In headwaters, residence times averaged 5 hours/km but increased to 7 years/km during low-flow conditions. Long-term accumulation for all stream classifications averaged ~5% of microplastic inputs per river …

Abl2 Promotes Alcohol-Associated Liver Disease Via Ppar Gamma Regulation, Gregory Malnassy

Dissertations

Alcohol-associated liver disease (AALD) is an umbrella term for a spectrum of diseases resulting from chronic alcohol (e.g. ethanol) abuse ranging in severity from reversible conditions such as alcohol-induced steatosis to advanced and largely irreversible liver pathologies including alcoholic steatohepatitis (ASH), alcoholic hepatitis (AH), fibrosis, cirrhosis, and hepatocellular carcinoma (HCC). AALD is one of the primary causes of chronic liver disease worldwide and accounts for 44% of liver disease deaths in the United States. Drinking rates, both in the United States and globally, have increased year over year for the past three decades, a trend which has resulted in significantly …

Las Chingonas: An Ecological Approach To Latina Student Mothers’ Journey Through College, Emely Elizabeth Medina-Rodriguez

Dissertations

Women with children are one of the growing student sub-populations in higher education. However, the support student mothers receive in colleges and universities has been historically unreliable and their experiences in college have not been studied in depth. This is especially true for student mothers from minoritized backgrounds with differing racial, ethnic, sexual, gender, and ability identities. This research aims to understand the experiences Latina graduate student mothers from an ecological and critical perspective. Guided by Critical Human Ecology and Black Feminist Thought, eight open-ended interviews were conducted and analyzed. Themes and categories came out of the patterns in the …

The Souls Of Black Folks In The Twenty-First Century: Self-Efficacy, Grit, And Their Development In Low-Income Urban Black Youth, Amzie Moore

Dissertations

Self-efficacy and grit have shown to be internal resources for African American youth, particularly urban low-income youth living in high crime and high poverty communities. This dissertation is a quasi-experimental, longitudinal, and mix method study, which evaluated a cross-age peer mentoring program. This evaluation was to examine if youth mentors’ attendance in the program for one year predicted increases in their self-efficacy and grit. The results of the study revealed that age significantly interacted with youth attendance, predicting increases in self-efficacy. Findings from the qualitative analyses illustrated that the peer-mentoring program strengthened culturally-relevant self-efficacy and grit among youth mentors.

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 …

The Role Of Glycogen Synthase Kinase 3 Β (Gsk-3Β) At The Cardiac Myofilament, Marisa Jean Stachowski

Dissertations

Altered kinase activity and localization is gaining appreciation as a mechanism contributing to cardiovascular disease. Previous work suggests that the kinase glycogen synthase kinase 3 β (GSK-3β) regulates contractile function of the myofilament, but this work was performed in vitro. The goal of this work was to investigate GSK-3β’s in vivo role in regulating myofilament function, the mechanisms involved, and the translational relevance in disease. GSK-3β’s myofilament localization was confirmed in wild type mouse and human tissue via western blot of myofilament enriched tissue and immunofluorescence. These experiments also revealed that GSK-3β phosphorylated at Y216 binds to the z-disc. We …

Healing Earth In A Time Of Crisis: Curriculum For Integral Ecology, Caleb Steindam

This intrinsic multiple case study examined secondary- and university-level educators’ experiences teaching with Healing Earth, a curriculum developed by the International Jesuit Ecology Project at Loyola University Chicago, which merges scientific, social, spiritual, and ethical analyses of pressing ecological issues. Based on the conceptual framework of integral ecology, Healing Earth is a response to Pope Francis’s (2015a) call for “a new way of thinking about human beings, life, society and our relationship with nature” (§215).

This study primarily consisted of in-depth interviews with educators who have used Healing Earth in a variety of secondary and post-secondary Catholic educational contexts. A …

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 …

Does Co-Speech Gesture Support Children’S Analogical Reasoning? An Investigation Into The Differential Effects Of Gesture On Learning, Amy Michelle Wilkinson

Dissertations

A well-established conceptualization of academic capitalism is rooted in the marriage of economic theory and critical social. Significantly, academic capitalism links economic dimensions with the political-ideological transformations of U.S. society associated with the fall of communism and the rise of neoliberalism. Academic capitalism is based on a recognition of the paradoxical nature of higher education and offers a lens through which to examine the ways in which institutions in the United States have come to prioritize learning for the labor market as a private good within the new global economy, while also becoming less beholden to the notion of learning …

Determination Of The Ecological Water Quality In The Orienco Stream Using Benthic Macroinvertebrates In The Northern Ecuadorian Amazon, Federico Sinche, Manuel Cabrera, Lenin Vaca, Edin Segura, Pablo Carrera

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 …

Fairness And Inclusion For Users Of Surface Transport—An Exploratory Thematic Study For Irish Users, Ajeni Ari, Maria Chiara Leva, Lorraine D'Arcy, Mary Kinahan

Articles

This paper explores the conditions of public transport with respect to user accessibility, design of infrastructure, and safety from a gendered perspective. Our investigation aims to understand the factors that direct a citizen’s choice of whether or not to use public transport. Our discussion is focused on gender disparities among user experiences, so we confine our focus to that of women’s perspectives and their experiences with public transport use. A framework for our discussion was formed with consideration of the theoretical aspects of fairness, justice, and gender in transport, as well as user statistics. We identified several spaces where public …

Viruses, Vaccines, And The Erotics Of Risk In Latinx Hiv Stories And Covid-19, Dr. Suzanne Bost

English: Faculty Publications and Other Works

In 2019, I published Shared Selves: Latinx Memoir and Ethical Alternatives to Humanism (University of Illinois Press), in which I discuss contagion as a metaphor for embracing our shared materiality with others. Six months later, during the Covid-19 pandemic, neighbors were crossing streets to avoid each other. Social distancing is, counterintuitively, asking us to view separation and seclusion as forms of solidarity. But how can we be solid if we are oriented against each other? Isolation itself has become contagious: sharing repulsion and rejection, measuring six feet of “social” distance from others. These spaces are made up of a variety …

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 …

Human resource is a key component in ramp handling operation and errors by employees cause significant accidents or incidents. The main purpose of the current study is to prioritize critical risk factors in ramp handling operations by using an integrated risk management approach and optimizing human performance while minimizing both failures and errors by employees. In this study, an integrated qualitative and quantitative risk assessment …

Establishing Commercial Aviation Safety Privilege: Court Precedent Versus Statute, Jason Powell

International Journal of Aviation, Aeronautics, and Aerospace

This concept paper evaluates the pros and cons of establishing commercial aviation safety privilege beyond the almost uniquely United States Department of Defense (DoD) legal protection built upon court precedence (stare decisis) as a statutory concept that can apply across all aviation investigations. The protection offered under Title 49 CFR 1114 only applies to the information provided that is not part of the safety investigation and allows full release of interviews that pertain to the investigation, which is further applied in the National Transportation Safety Board Aviation Investigation Manual (2002). The Supreme Court of the United States recognized different privileged …

Aircraft Interior And Seat Design: Priorities Based On Passengers’ Opinions, Peter Vink, Gerbera Vledder, Yu Song, Britta Herbig, Anna Sophie Reichherzer, Neil Mansfield

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 …

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 …

The Necessity Of Global Standardization Guidelines For Space Travel, Joshua Larson, Mallory K. Casebolt

International Journal of Aviation, Aeronautics, and Aerospace

This study explored the interest in global standardization guidelines for space travel. Due to the lack of accepted minimum international standards and commercialized space travel guidelines, there is a need to explore the feasibility of developing of an agency or clearinghouse for the standardization of certifications, requirements, and ethical standards for space travel between global governments and private entities. This study employed a two-round Delphi design to investigate the need to establish and prioritize such guidelines. The findings yielded from this study provide guidance on how an agency or clearinghouse is needed and could potentially aid in developing such guidelines. …
