Comparison Of Condensation Nuclei Counter And Controlled Negative Pressure Methods Under Different Environmental Conditions Tested With A Mannequin And Human Subjects, Olanrewaju John Fadairo

Graduate Theses, Dissertations, and Problem Reports (ETD)

Continuing concern about exposure to respiratory hazards at various workplaces and prevalent pandemics such as H1N1/09 influenza and COVID-19, have necessitated a need for more research regarding respirators. Quantitative fit testing (QNFT) is a critical component of an OSHA compliant respiratory protection program. QNFTs are often performed in environments where temperature and relative humidity (RH) vary. However, no study has investigated the possible effects of these parameters on penetration and QNFT results.

This comparative study utilized condensation nuclei counter (CNC) and controlled negative pressure (CNP) methods to quantitatively determine simulated mannequin fit factors (SMFFs) and human fit factor (HFFs) using …

State Counter-Insurgency And Political Policing In Colonial And Post-Colonial Malawi, 1891-1994, Paul Brenard Chiudza Banda

Graduate Theses, Dissertations, and Problem Reports (ETD)

This is a study that adopts the longue durée historical approach to analyze the main causes behind the rise of ‘insurgencies’ or the so-called resistance against the colonial and post-colonial state in the present-day southern African country called Malawi from 1891 to 1994. In turn, it also uses the concept of ‘counter-insurgency’ to analyze the various measures the states in question used to defeat the ‘insurgents’. To arrive at the conclusions made in the study, I have migrated through various domestic and transnational spaces, personalities, and documents that inform the current study. I also adopt two main historical approaches to …

Description Of Motor Control Using Inverse Models, Anton Sobinov

Graduate Theses, Dissertations, and Problem Reports (ETD)

Humans can perform complicated movements like writing or running without giving them much thought. The scientific understanding of principles guiding the generation of these movements is incomplete. How the nervous system ensures stability or compensates for injury and constraints – are among the unanswered questions today. Furthermore, only through movement can a human impose their will and interact with the world around them. Damage to a part of the motor control system can lower a person’s quality of life. Understanding how the central nervous system (CNS) forms control signals and executes them helps with the construction of devices and rehabilitation …

The objectives of this study were 1) to compare factors associated with different type of opioid overdose, 2) to determine the conditional probability of repeat overdose among veterans with a prior overdose event and corresponding probability of mortality for each overdose event and, 3) to identify cause-specific mortality rate of those who experienced a …

Supporting The Injured Athlete: Coaches’ Perspectives On Providing Social Support, Stefanee Opal Maurice

Graduate Theses, Dissertations, and Problem Reports (ETD)

Injury is an inevitable facet of sport participation, and injured athletes require support from coaches. However, research on injured athletes highlights a lack of support from coaches. Building on the conceptual model proposed by Maurice et al., this study uses the International Sport Coaching Framework (ISCF) to examine ways contextual coaching knowledge is used to support athletes throughout rehabilitation. Previous research has focused on the knowledge types but has neither addressed the integration of the knowledges in a single study nor examined them in an injury context. A generic qualitative approach was used to examine 13 NCAA DI coaches’ perception …

The Effects Of Obesity, Chronic Stress, And Exercise On Pancreatic Health, Abigail Tice

Graduate Theses, Dissertations, and Problem Reports (ETD)

Obesity is concomitant with hyperglycemic conditions, increased proinflammatory cytokines, and increased oxidative stress. Under hyperglycemia, thioredoxin interacting protein (TXNIP) is increased and causes increased oxidative stress and pancreatic b-cell apoptosis. Chronic stress is associated with increased glucocorticoid levels and a proinflammatory environment. The purpose of this study was to examine the effects of obesity, chronic stress, and exercise on pancreatic health.

Lean Zucker Rats (LZRs) and Obese Zucker Rats (OZRs) were randomly assigned to four groups: 1) sedentary controls (C: n=8 per); 2) unpredictable chronic mild stress (UCMS) (S: n=8); 3) exercise (E: n=8); and 4) combined UCMS and exercise …

Health Literacy And Family Factors In The Transition To Adult Care In Adolescents With Type I Diabetes, Ellen M. Manegold

Graduate Theses, Dissertations, and Problem Reports (ETD)

Successful management of type 1 diabetes (T1DM) in adolescence involves multiple daily tasks, developmental changes, and the expectation of transition to an adult provider. Health literacy is one variable to consider in the context of transition, as studies have demonstrated the correlation of parental health literacy with health behaviors and outcomes, yet not studied adolescent health literacy in T1DM. Family factors (e.g., management responsibility, diabetes-specific family conflict, parental support) also are important to behavior and health outcomes in adolescents with T1DM. Study aims were to: 1) examine the association of adolescent health literacy to transition readiness and health outcome in …

Trustworthiness And Stability In Same And Different Sex Relationships: Heterosexuals’ Attitudes Toward Bisexuality, Jeneice Shaw

Graduate Theses, Dissertations, and Problem Reports (ETD)

Although bisexuals are reportedly the largest sexual orientation minority group in North America (Copen, Chandra, & Febo-Vazquez, 2016), there is scant research examining the population without also including lesbian women and gay men. However, according to the American Psychological Association’s (2012) Guidelines for Psychological Practice with Lesbian, Gay, and Bisexual Clients, psychologists should endeavor to understand the unique experiences of the bisexual population. Bisexual individuals face different stereotypes, conflict within the LGB community, and different life experiences related to other sexual orientations (Rust, 2000). Two unique stereotypes applied to the bisexual community are that bisexuality is an unstable sexual orientation …

Specifically, this study investigates interpretive journalism in the context of political news coverage and also examines the relationship between political ideology and the aforementioned variables. This study uses a 2 (interpretive journalism; fact-based journalism) x 2 (political ideology: conservative leaning; liberal leaning) between-subjects online experiment to test the proposed hypotheses. Findings illustrate the predictive value of credibility to trust within the context of political news coverage. Additionally, this study shows that individuals exhibit higher perceptions of trust and credibility towards fact-based political coverage as opposed to interpretive …

A Sociopolitical Perspective To Understand When And Why Supervisors Endorse And Implement Employees’ Suggested Changes, Huaizhong Chen

Graduate Theses, Dissertations, and Problem Reports (ETD)

When employees make suggestions for changes to their supervisors, they are providing raw materials potentially critical to the organization’s continuous improvement and adaptation. However, research suggests that supervisors do not always react favorably to employee voice behavior. The purpose of this study is to unravel the mediating and moderating mechanisms that can explain when and why employee voice behavior leads to supervisor endorsement and implementation. Specifically, taking a sociopolitical perspective, I argued that supervisor motive attributions for employee voice behavior can explain the extent to which supervisors endorse and subsequently implement employee voice. Furthermore, I argued that the mediating effects …

Electrochemical Detection Of Fentanyl Using Screen-Printed Carbon Electrodes With Confirmatory Analysis Of Fentanyl And Its Analogs In Oral Fluid Using Liquid Chromatography-Tandem Mass Spectrometry, Colby E. Ott

Graduate Theses, Dissertations, and Problem Reports (ETD)

Utilizing screen-printed carbon electrodes (SPCEs), a fast, simple, and sensitive approach toward the detection, identification, and quasi-quantitation of fentanyl was achieved both in an electrochemical cell and as a drop on the electrode surface. Electro-oxidation of fentanyl at the electrode was demonstrated using adsorptive stripping square-wave voltammetry between -0.5 V and +1.6 V with 100 mM Tris-HCl buffer at pH 8.5 as supporting electrolyte. Parameter optimization was conducted during method development to include supporting electrolyte and pH, electrochemical technique, pre-treatment and equilibration time, and various surface modifications. The simplest method utilizing an unmodified SPCE was determined to be appropriate for …

A Randomized Controlled Trial Of Parent-Child Interaction Therapy With And Without Incentives In A Community Mental Health Setting, Lauren Borduin Quetsch

Graduate Theses, Dissertations, and Problem Reports (ETD)

Disruptive behavior disorders (e.g., oppositional defiant disorder, conduct disorder) are the leading cause of referrals for children in mental health settings. Significant advancements in the implementation and dissemination of evidence-based family therapies have yielded successful reductions in these problem behaviors while also promoting long-term outcomes. Unfortunately, effective interventions such as Parent-Child Interaction Therapy (PCIT) are plagued with high rates of attrition and low rates of homework completion in community clinics. The current research study focused on evaluating the use of low cost incentives to increase retention and homework adherence in PCIT for a sample of low income, largely Hispanic families. …

Internalized Heterosexism, Outness, Athletic Identity, And Perceived Stress Among Queer Female Athletes, Olivia C. Scott

Graduate Theses, Dissertations, and Problem Reports (ETD)

The historical presence of heterosexism in sport has been discussed in numerous publications, with unique considerations for female athletes (Anderson, Magrath, & Bullingham, 2016; Cahn, 1993; Griffin, 1998; Rankin, 1998). Unfortunately, few studies have examined the impact of this climate on female athletes with minoritized sexual identities. Most research pertaining to this population has been qualitative and largely focused on lesbian athletes (Fynes & Fisher, 2016; Stoelting, 2011). Consequently, more generalizable conclusions about queer female athlete experiences has been limited. The present study was an attempt to address this research gap, by assessing the internalized heterosexism, outness, athletic identity, and …

The Parent-Child Interaction Therapy Family Experiences And Feedback Study: A Follow-Up Examination Of Attrition In An Evidence-Based Treatment In Community Settings Statewide, Brittany K. Liebsack

Graduate Theses, Dissertations, and Problem Reports (ETD)

Attrition is a significant problem in child psychotherapy (De Haan, Boon, De Jong, Hoeve, & Vermeiren, 2013) and has serious implications (Barrett et al., 2008). Predictors of attrition include those at the client, therapist, and treatment levels. The current study investigated variables associated with attrition in Parent-Child Interaction Therapy (PCIT), an evidence-based parent training program for families with young children (ages 2.5- to 7-years-old) with disruptive behavior disorders. The sample of 67 caregivers were treated by 25 therapists from 19 different licensed psychiatric outpatient clinics across one state and were part of a larger study (RO1 MH09750; A Statewide Trial …

An Investigation Of The Relation Between Mindfulness And Self-Esteem Stability, Cameron Grant Ford

Graduate Theses, Dissertations, and Problem Reports (ETD)

Self-esteem stability is the magnitude of the short-term fluctuations in one’s immediate feelings of self-worth (Kernis, 2005). Stable self-esteem is associated with several psychological benefits, such as lower depression (Kernis et al., 1998). However, it is unknown what factors lead to self-esteem stability. Because mindfulness promotes a nonjudgmental orientation whereby thoughts, feelings, and reactions are viewed as transient events that do not necessarily represent objective reality, mindfulness might be associated with more stable self-esteem. Thus, the present research examined the relation between mindfulness and self-esteem stability. Undergraduates (N = 190) were randomly assigned to one of three conditions: mindfulness …

Eyewitness Memory Recall In Adolescents With Callous-Unemotional Traits, Benjamin Dylan Thomas

Graduate Theses, Dissertations, and Problem Reports (ETD)

Individuals with high levels of psychopathic traits have been portrayed as having higher intelligence and better memory (Cleckley, 2015). In terms of developmental pathways for psychopathy, the strongest predictor of children and adolescents developing psychopathic traits in adulthood is high levels of callous-unemotional (CU) traits in childhood (Burke et al, 2007; Frick, 2009). Research has been mixed with regard to links between CU or psychopathic traits and memory performance in children and adults, with some studies finding that individuals with high levels of these traits demonstrated poorer memory performance (Bauer & Hesselbrock, 2001; Dolan & Fullam, 2005). This study examined …

Choose Your Own Lecture: Students’ Motivational Resources As A Consequence Of Autonomy-Supportive Instruction, James P. Baker

Graduate Theses, Dissertations, and Problem Reports (ETD)

The purpose of this dissertation was to extend the self-determination theory literature by investigating the utility of the choose your own lecture method of instruction. This method of instruction allows students to control the direction of a lesson. In line with the theoretical propositions of SDT, the researcher hypothesized that this style of teaching would support students’ inner motivational resources (i.e., autonomy-need satisfaction and intrinsic motivation) and in turn, foster students’ interest in the topic of the lesson, free-choice persistence, cognitive learning, affect for the course, and expressive dissent. A 50-minute live-lecture experiment on environmental communication (climate change, risk communication, …

Tie Strength, Optimal Connections, And Distance In Social Networks, David Anthony Buch

Graduate Theses, Dissertations, and Problem Reports (ETD)

Social network analysis seeks to understand the structure of relationships in networks of actors. As researchers identify structural properties of interest (e.g. vulnerability to network cuts) they introduce measures to quantify the expression of those properties in observed networks. In fact, it is not uncommon that multiple measures are introduced purporting to evaluate a single property. Relative merits of competing measures are not self-evident but the corresponding inferences can conflict, encouraging arbitrary choice among measures and endangering the validity of conclusions. We argue (i) that multiplicity of measures is a necessary consequence of the de rigueur practice of conflating different …

It identifies the Quaker traditions that shaped the work of the FAU and FRS—particularly the …

Short-Term Abstinence Effects In Experienced Electronic Cigarette Users, Nicholas J. Felicione

Graduate Theses, Dissertations, and Problem Reports (ETD)

Nicotine/tobacco dependence is a problem that negatively affects health at an individual and population level. Nicotine/tobacco dependence may be best assessed by measuring withdrawal symptoms of a nicotine/tobacco user who abstains from use. Withdrawal symptoms experienced by cigarette smokers are well characterized, including deficits in attention and memory, as well as self-reported cravings, urges, and other symptoms. While withdrawal in cigarette smokers has been studied extensively, little is known about dependence and withdrawal associated with newer products, such as electronic cigarettes (ECIGs). ECIGs can deliver nicotine comparably to tobacco cigarettes, indicating that they may have the potential to cause dependence. …

Behavioral Impairment Following Gestational Exposure To Titanium Dioxide Nanomaterial Aerosols In Male And Female Rats, Matthew Leland Eckard

Graduate Theses, Dissertations, and Problem Reports (ETD)

Engineered nanomaterials (ENMs) are beginning to be recognized as hazardous to human and animal health. Titanium dioxide (TiO2) is primarily used as a whitening agent in paints, plastics, and sunscreens. While relatively inert in its bulk form, nano-TiO2 (diameter) can produce prolonged inflammation and oxidative stress in target tissue. Recently, the potential for nano-TiO2 to cause neuroinflammation and damage has heightened concerns about its continued use. One important concern is that nano-TiO2, and other metal oxide ENMs, may affect fetal neurodevelopment. Accordingly, it is imperative to screen ENMs, like TiO2, for possible neurotoxicity following developmental exposures. The current set of …

Groups included dentate, implant overdenture, and conventional denture.

Methods: Counter movement jumping with force plate collection was utilized to test the three populations in this study. The three populations were dentate, mandibular implant overdenture opposing maxillary complete denture, and conventional maxillary and …

Determinants Of Control-Key Responding In An Operant Resurgence Procedure, Anthony C. Oliver

Graduate Theses, Dissertations, and Problem Reports (ETD)

The Control response in a resurgence procedure has been described as the “gold standard” in isolating resurgence from other extinction-induced phenomena. Although Control responding is not generally observed during the resurgence test phase of animal-resurgence procedures, it is common to see such responding in human-operant resurgence procedures. Thus, it is necessary to identify the conditions under which Control responding may be observed. Using pigeons and rats as subjects, the current series of experiments examined the determinants of Control-operandum responding in a resurgence procedure. Experiment 1 assessed whether behavior with a pre-experimental reinforcement history would resurge if the Target response was …

An Assessment Of Emotional-Force And Cultural Sensitivity The Usage Of English Swearwords By L1 German Speakers, Sarah Dawn Cooper

Graduate Theses, Dissertations, and Problem Reports (ETD)

This study examines the usage of English swearwords by L1 German speakers and poses the following three questions: (1) Which English swearwords do native-speakers of German use? (2) In which situations do German speakers use English swearwords? Why do they use English swearwords instead of their German counterparts? (3) What emotional weight do they apply to swearwords in English (i.e. How taboo are they)? In an effort to understand Germans’ use of swearwords today, potential attributing factors were assessed and evaluated in a 15-question survey comprised of both qualitative and quantitative components that was taken by 403 participants from Germany …
