The Impact Of Affiliative Motivation And Trust On Confrontations Of Racism, Jamie Patrianakos

Dissertations

Anti-Black racism persists in the United States with harmful consequences for Black people. White people are able to disrupt the racial status quo and propel the conversation about racial justice forward by confronting racism. Confronting perpetrators of racism can reduce prejudice, yet people hesitate to confront because they fear social backlash, even from those with whom they share a social bond. Two online studies asked participants to complete a task eliciting stereotypical responding while being observed by a supposed interaction partner with whom they shared either a high or low desire to get along. Participants were confronted by their interaction …

Cardioprotective Extracellular Vesicles Derived-Micrornas: Sorting Mechanisms And Functions, Anh P. Phan

Dissertations

Extracellular vesicles (EVs) are nano-size membrane bound vesicles that are derived from the fusion of multivesicular endosomes with the plasma membranes. EVs have important roles in intercellular communication through the transfer of their unique cargoes including RNA, DNA and protein molecules to recipient cells. Mesenchymal stem cell (MSC)-derived EVs have been shown to reduce infarct size and reduce the progress of heart failure after cardiac ischemia/reperfusion (I/R) injury in animal models. Small non-coding RNAs such as microRNA (miRNA) have been indicated as one of the active components that mediate the beneficial effects of MSC-derived EVs. However, the selective packaging mechanisms …

Dissertations

Loyola University Chicago MOVING BEYOND RECRUITMENT AND HIRING: INCLUDING AND ACTUALIZING THE VOICES OF TEACHERS OF COLOR IN A SUBURBAN SCHOOL DISTRICT This capstone identifies, as a problem of educational practice in American secondary schools, the failure of our school systems to equally value and validate Black and brown educators as compared with their white counterparts, consequently preventing the cultivation of an environment that would encourage these educators to flourish in the profession rather than presenting barriers to their success. Calling upon the prevailing research, Ms. Rowe evaluates approaches that school districts can take to overcome these roadblocks and foster …

Dying To Fight: The Individual And Social Processes Of The Foreign Fighter Phenomenon, Michael James Schumacher

Dissertations

Why do individuals take the extraordinary risk of traveling abroad to fight, and potentially die, in another country's conflict? This dissertation compares the motivations behind the U.S. citizens who fought on behalf of the International Brigades in the Spanish Civil War (1936-1939) and the Tunisian citizens who fought on behalf of the Islamic State of Iraq and Syria (ISIS) in the Syrian Civil War (2011 - present). The study relies on personal narratives of individual foreign fighters collected through twelve weeks of archival research at the Tamiment Library in New York City and the Ernest Hemingway Archives in Boston dedicated …

Environmental Reforestation And Social Justice In Cameroon: A Test Case For Pope Francis' Concept Of 'Integral Ecology' In Laudato Sí, Augustin Vondou

Dissertations

The following quotation from Pope Francis' encyclical Laudato Sí is one of the most quoted parts of his well-known encyclical: We are faced not with two separate crises, one environmental and the other social, but rather with one complex crisis which is both social and environmental. Strategies for a solution demand an integrated approach to combating poverty, restoring dignity to the excluded, and at the same time protecting nature (139).

This is a very challenging statement. Not everyone accepts this idea of an ‘integral ecology’; that is, the notion that the condition of human society is directly linked to the …

Pediatric Mental Health Hospitalizations And The Return To School: School-Based Provider Perspectives On Commmunication, Collaboration, And Systematic Practices, Lauren Elizabeth Carr

Dissertations

The provision of pediatric mental health services has changed greatly over the last several decades with more children and adolescents requiring intensive mental health treatment. Despite this increase, systemic barriers continue to prevent youth from receiving appropriate treatment following psychiatric hospitalization. An important aspect of this treatment process includes a child’s return to school, one of the most common environments for a child or adolescent outside of their home. For many children, the hospital-to-school transition team may include regular and special education teachers, school psychologists, social workers or therapists, psychiatrists, medical doctors, case managers, and nurses. Because of this, it …

Standardizing Thoracic Aortic Aneurysm Education, Marjorie Anne Gisslow

Master's Projects and Capstones

Problem: Patients receive information about a new thoracic aortic aneurysm (TAA) diagnosis from their primary care providers (PCPs). As TAA is a relatively rare conditions, many PCPs have rudimentary knowledge of TAA, and need information and support from cardiac specialists to address their patients’ concerns and guide their care.

Context: In the Regional TAA Surveillance Program the TAA nurses offer educational content for patients through the information they provide to the PCPs. Currently the educational material available to PCPs is not comprehensive or easily accessible.

Intervention: Uniform, comprehensive educational content provided through recommendations in the patient’s electronic medical record at …

Wastewater Treatment Alters Microbial Colonization Of Microplastics, John J. Kelly, Maxwell G. London, Amanda R. Mccormick, Miguel Rojas, John W. Scott, Timothy J. Hoellein

Biology: Faculty Publications and Other Works

Microplastics are ubiquitous contaminants in aquatic habitats globally, and wastewater treatment plants (WWTPs) are point sources of microplastics. Within aquatic habitats microplastics are colonized by microbial biofilms, which can include pathogenic taxa and taxa associated with plastic breakdown. Microplastics enter WWTPs in sewage and exit in sludge or effluent, but the role that WWTPs play in establishing or modifying microplastic bacterial assemblages is unknown. We analyzed microplastics and associated biofilms in raw sewage, effluent water, and sludge from two WWTPs. Both plants retained >99% of influent microplastics in sludge, and sludge microplastics showed higher bacterial species richness and higher abundance …

Biostatistics Collaborative Core: Faculty Publications and Other Works

Objective: The aim of this study was to determine the association of low antihypertensive medication adherence with decline in health-related quality of life (HRQOL) over 1 year.

Methods: We used data from older men and women with hypertension (n¼ 1525) enrolled in the Cohort Study of Medication Adherence among Older Adults. Adherence was measured using the validated self-report four-item Krousel-Wood Medication Adherence Scale (K-Wood-MAS-4) (low adherence¼ score 1) and prescription refill-based proportion of days covered (PDC) (low adherence¼ PDC< 0.80). We defined decline in HRQOL as a decrease in Mental Component Summary (MCS) or Physical Component Summary (PCS) score (from the RAND 36-Item Health Survey 1.0 administered at two time points – at the time of adherence assessment and 1 year later) equivalent to the minimal important difference (MID) for each respective summary score, calculated as the average of MID estimates derived from distribution and anchor-based approaches.

Results: The prevalence of low adherence was 38.6% using the K-Wood-MAS-4 and 23.9% using PDC. On the basis of mean MID …

The Effects Of Technological Supervision On Gig Workers: Organizational Control And Motivation Of Uber, Taxi, And Limousine Drivers, Peter Norlander, Nenad Jukic, Arup Varma, Svetlozar Nestorov

School of Business: Faculty Publications and Other Works

Does supervision from technological platforms alter gig workers’ motivation and perceptions of control? We address this question with two field studies set in the passenger livery (pick up and drop off) industry. A between-subjects field survey (n = 50) finds that UberX drivers perceive significantly greater organizational control compared to taxi drivers, but do not report significantly different levels of intrinsic motivation, needs satisfaction, or enjoyment of work. In a follow-up within-subjects field experiment (n = 79), we identify the causal impact of technological supervision on drivers’ perceptions of control and motivation. Black car limousine drivers who sometimes …

Ethical Health Care In An African Context: Linking Conventional Medicine And Traditional Healing Practices In Igboland, Nigeria., Michael Osondu Okoro

Dissertations

This dissertation argues that in Nigeria’s Igboland, a health care ethic reflective of the Roman Catholic Christian faith must build links between the rightful practices of both conventional Western medicine and traditional Igbo healers. It calls such a health care ethic an “integral health care ethic” in the Nigerian Igbo context.The inspiration for this dissertation comes from the growing respect given to indigenous people and their knowledge by the Roman Catholic Church since the Second Vatican Council and, more specifically, the attention Pope Francis has given to indigenous people in his writings and speeches. For example, in his remarks on …

Files Cryptography Based On One-Time Pad Algorithm, Ahmad Mohamad Al-Smadi, Ahmad Al-Smadi, Roba Mahmoud Ali Aloglah, Nisrein Abu-Darwish, Ahed Abugabah

All Works

The Vernam-cipher is known as a one-time pad of algorithm that is an unbreakable algorithm because it uses a typically random key equal to the length of data to be coded, and a component of the text is encrypted with an element of the encryption key. In this paper, we propose a novel technique to overcome the obstacles that hinder the use of the Vernam algorithm. First, the Vernam and advance encryption standard AES algorithms are used to encrypt the data as well as to hide the encryption key; Second, a password is placed on the file because of the …

Automatic Fall Risk Detection Based On Imbalanced Data, Yen-Hung Liu, Patrick C. K. Hung, Farkhund Iqbal, Benjamin C. M. Fung

All Works

In recent years, the declining birthrate and aging population have gradually brought countries into an ageing society. Regarding accidents that occur amongst the elderly, falls are an essential problem that quickly causes indirect physical loss. In this paper, we propose a pose estimation-based fall detection algorithm to detect fall risks. We use body ratio, acceleration and deflection as key features instead of using the body keypoints coordinates. Since fall data is rare in real-world situations, we train and evaluate our approach in a highly imbalanced data setting. We assess not only different imbalanced data handling methods but also different machine …

Small Unmanned Aircraft Systems Acoustic Analysis For Noninvasive Marine Mammal Response: An Exploratory Field Study, David Thirtyacre, Gennifer Brookshire, Sarah Callan, Brittany Arvizu, Patrick Sherman

International Journal of Aviation, Aeronautics, and Aerospace

As in countless other fields of human endeavor, small unmanned aircraft systems (sUAS) have the potential to benefit pinniped (Pinnipedia; e.g., Phocidae [seals], Otariidae [sea lions], and Odobenidae [walruses]) response efforts. The employment of sUAS could give responders a close-up look at animals in distress in order to determine their condition as well as develop a response strategy. However, unlike other subjects that are regularly inspected by sUAS (e.g., croplands and civil infrastructure) pinnipeds may respond to the distinctive sound generated by small, multirotor sUAS. This reaction may include retreating into the water en masse, which could put …

How Duty Rosters And Stress Relate To Sleep Problems And Fatigue Of International Pilots, Marion Venus, Martin Grosse Holtforth

Evaluating The Emerging Environmental Risks Of Mycotoxins In Freshwater Ecosystems., Emily Eagles

School of Geography, Earth and Environmental Sciences Theses

Deoxynivalenol (DON) and zearalenone (ZON) are two of the prominent mycotoxins which regularly contaminate food, both of these natural toxins are produced by fungi within the Fusarium genus. With the known widespread occurrence of these toxins in cereal crops there has been rising interest into the potential transference into freshwaters. Multiple reports of mycotoxin occurrence in freshwater samples have led to their consideration as natural chemicals of emerging concern, particularly with ZON seen to act in an oestrogenic nature, yet the ecotoxicological data to support analysis of risk to freshwater ecosystems is lacking. The main aim of this work was …
