Female Police Officers' Perceptions And Experiences With Marginalization: A Phenomenological Study, Dr. Arlether Ann Wilson

Walden Dissertations and Doctoral Studies

There is a lack of female police officer representation in police departments nationwide. Women's position, or lack thereof, in law enforcement is a topic of discussion in many police literature reviews. However, there were minimal studies detailing female police officers' personal experiences in the law enforcement profession. The purpose of this phenomenological study was to describe and understand the perceptions and lived experiences of female police officers, as well as the impact those experiences had on their careers. Female participants from 3 police departments formed the purposive sample that included 8 full-time female police officers. The feminist theory helped to …

Assessing The Impact Of Yoga As A Moderator On Substance Abuse Treatment Effectiveness, Joseph Antonio Mcdaniel

Walden Dissertations and Doctoral Studies

Self-efficacy and treatment adherence reduce substance dependence. Yoga has been suggested as an adjunct to substance dependence treatment to enhance outcomes. This study was designed to assess yoga as a moderator of substance abuse treatment effectiveness, as indicated by the Exercise Self-Efficacy survey and Treatment Effectiveness Assessment scores. This study was guided by self-efficacy theory and used a nonequivalent quasi-experimental design to evaluate self-efficacy changes and treatment effectiveness. A drug treatment program that did not incorporate yoga as an adjunct to treatment was compared to another treatment program that did. Convenience sampling strategy was utilized to recruit 100 voluntary yoga …

An Interpretive Phenomenological Investigation Of The Meaning Of Job Satisfaction Among Veteran Special Educators, Raeann Barnes

Walden Dissertations and Doctoral Studies

The attrition rate among special education teachers is ranked among the highest in the education profession. Retaining teachers early in their careers continues to be a concern due to increased job responsibilities, larger caseloads, challenging student behaviors, minimal support from colleagues, increased paperwork, and diminishing resources. The purpose of this phenomenological study was to examine the meaning of satisfaction special education teachers made of their careers. The transactional model developed by Lazarus and Folkman (1984) can help to explain how the occurrence of stressful events can impact an individual. A purposive sample of 9 tenured, certified special education teachers currently …

Exploring Barriers To Fathers' Implementation Of Behavioral Interventions For Nonverbal Children With Autism, Michael Lafasakis

Walden Dissertations and Doctoral Studies

Many families, regardless of their ethnic and cultural background, find it challenging to raise a nonverbal child with autism. Parent-implemented behavioral interventions can contribute to positive behavior change related to joint attention, imitation, and communication. However, many parents face barriers that prevent them from implementing behavioral interventions in the home. Very little research has been conducted on fathers of nonverbal children with autism to ascertain their perspectives on these barriers. In this qualitative study, a phenomenological design was used to obtain input from 12 fathers of diverse ethnic and cultural backgrounds residing in New York City regarding barriers to implementing …

Chronic Pain Causal Attributions In An Interdisciplinary Primary Care Clinic: Patient-Provider And Provider-Provider Discrepancies, Bryan Jensen

Theses and Dissertations

The purpose of the present study was to investigate the influence of pain causal attributions on patient pain-related functioning, treatment engagement, and clinical outcomes. Additionally, the impact of discordant pain causal attributions between patients and their providers as well as between interdisciplinary providers was examined. Patients rated their pain functioning and causal pain attributions during a regular clinic visit. Following the patient’s visit both the behavioral medicine provider and internal medicine resident provided ratings of similar pain-related functioning domains and causal attributions. Follow-up data were collected from the electronic medical record three months following that clinic visit. Overall, results revealed …

Identifying Misconceptions Associated With Inaccurate Survey Reporting In The Combined Use Of Caffeine And Alcohol, Kathryn Polak

Theses and Dissertations

Research on college student use of caffeine combined with alcohol (CAC) and public health concern over such use has been hampered by the absence of psychometrically sound measures of caffeine and CAC use. The present study examined agreement between survey (CAS) and interview (TLFB) methods for collecting data on caffeine, alcohol and CAC use. Participants were N=50 college students randomized to complete CAS followed by TLFB or the reverse. Qualitative follow-up interviews with N=15 participants were used to identify factors contributing to CAS-TLFB discrepancies. Responses varied by method of administration, with largest discrepancy magnitudes found for CAC, followed …

Factors Predicting African American Renal Patients’ Completion Of The Medical Evaluation Process For Kidney Transplantation, Camilla W. Nonterah

Theses and Dissertations

African Americans (AA) are more susceptible to end-stage renal disease (ESRD) for several reasons. Treatment options for patients with ESRD include dialysis therapy and transplantation, with the latter typically producing better outcomes. AA are less likely to complete the medical evaluation process, which requires patients to consult with doctors and undergo a series of tests and examinations. This study sought to determine the factors that predict completion of the medical evaluation for AA ESRD patients using a mixed methods design. Participants consisted of transplant professionals (N=23) recruited from nine transplant centers in the Mid-Atlantic, Mid-Western and Southeastern parts …

The Relationship Between Christian Religiosity And Heterosexism In The Southern United States, Patricia Hare

Walden Dissertations and Doctoral Studies

The internalization of heterosexism places lesbian, gay, and bisexual (LGB) individuals at disproportionately higher risks of depression and self-destructive behaviors. For LGB Christians, this phenomenon is often exacerbated. Although literature on heterosexism has increased, little research has examined more insular, religious environments. The purpose of this study was to examine the relationship between Christian denominational religiosity and heterosexism and to compare the degree of religiosity and heterosexism between members of 5 Christian denominations and between same-sex sexuality perspectives in the southern United States. Guided by the attribution theory, a correlational, cross-sectional survey design was used to analyze degree of religiosity …

The Use Of Online Supplemental Materials In College Courses To Improve Retention, Amy Lynn Hennings

Walden Dissertations and Doctoral Studies

First-generation college students continue to have lower retention and success rates in colleges and universities, reducing their likelihood of staying above the poverty line. The study tested Bandura and Vygotsky's social cognitive theories of self-efficacy, self-regulation, and student ability to self-pace in the classroom. The purpose of this study was to explore if offering supplemental online materials to traditional class delivery, which can be self-regulated and self-paced, impacted students' success rates in the class and semester-to-semester retention. Using a quasi-experimental method, first-semester college students, in a small private liberal arts college (N = 678); were compared on use of supplemental …

Motivating Parents Of Kids With Asthma To Quit Smoking: The Effect Of The Teachable Moment And Increasing Intervention Intensity Using A Longitudinal Randomized Trial Design, Belinda Borrelli, Erin M. Tooley

Arts & Sciences Faculty Publications

Aims—We tested two aims: 1) The Teachable Moment (TM): whether second hand smoke exposure (SHSe) feedback motivates cessation in parents of children with asthma vs. parents of healthy children (HC) and 2) whether greater intervention intensity (Enhanced-PAM) produces greater cessation than a previously tested intervention (Precaution Adoption Model; PAM).

Design and interventions—Aim 1: Two home visits (asthma education or child wellness), and cessation induction using Motivational Interviewing and SHSe feedback. Aim 2: Post home-visits, parents with asthmatic children were randomized to PAM (n=171; 6 asthma education calls) or Enhanced-PAM (n=170; 6 asthma education/smoking cessation calls + repeat SHSe …

Prevalence, Reasons For Use, And Risk Perception Of Electronic Cigarettes Among Post-Acute Coronary Syndrome Smokers, Andrew M. Busch, Erin M. Tooley

Arts & Sciences Faculty Publications

Purpose—The use of electronic cigarettes (e-cigarettes) has risen dramatically in recent years. However, there is currently no published data on use of e-cigarettes among cardiac patients. The current study reports on the prevalence, reasons for use, and perceived risks of e-cigarettes among post-Acute Coronary Syndrome (ACS) patients. The relationship between e-cigarette use and post- ACS tobacco smoking cessation is also explored.

Methods—Participants were drawn from a randomized trial of smoking cessation treatments following hospitalization for ACS. The current study focuses on 49 participants that completed e- cigarette questions at 24 weeks post-ACS.

Results—51.0% of participants reported ever …

Comparison Of Secondhand Smoke Exposure In Minority And Non-Minority Children With Asthma, David A. Fedele, Erin M. Tooley

Arts & Sciences Faculty Publications

Objective—Determine if secondhand smoke exposure (SHSE) is related to asthma-related functional morbidity by examining racial/ethnic differences in Non-Latino White (NLW), African American, and Latino families and whether racial/ethnic SHSE differences across families persist when accounting for smoking factors.

Methods—Participants were 305 caregiver smokers of children with asthma. Two passive dosimeters measured SHS: one in the home and one worn by the child.

Results—Higher SHSE was related to greater asthma-related functional morbidity. African Americans had higher levels of home SHSE than Latinos (p = .003) or NLWs (p = .021). SHSE as assessed by the child …

Investigating The Effects Of A Parent-Mediated Intervention On Latino Parent-Child Verbal Interaction And Children's Receptive Vocabulary, Patricia G. Onorato

Theses and Dissertations

This study aimed to investigate parent-child verbal interactions in Spanish in a group of Latino preschoolers growing up in the United States through a parent-mediated program at home, and the effects of the program on their receptive vocabulary in Spanish. A single subject multiple baseline across participants design was used in the study. The participants were 3 Latino mothers and their sons, with low family income, living in the United States. The intervention taught the mothers strategies to enhance their children’s language through a sharing-book activity. The study lasted for 6 weeks during which baseline and intervention conditions data were …

Cognitive Evidence Of Fish Sentience, Jonathan Balcombe

Animal Sentience

I present a little-known example of flexible, opportunistic behavior by a species of fish to undermine Key’s (2016) thesis that fish are unconscious and unable to feel. Lack of a cortex is flimsy grounds for denying pain to fish, for on that criterion we must also then deny it to all non-mammals, including birds, which goes against scientific consensus. Notwithstanding science’s fundamental inability to prove anything, the precautionary principal dictates that we should give the benefit of the doubt to fish, and the state of the oceans dictates that we act on it now.

Mediating Claims Through Critical Anthropomorphism, Gordon Burghardt

Animal Sentience

Key’s (2016) discussion of his claim that fish do not feel pain ignores the history of attempts to study the attribution of mental states to other species. Although willing to accept that mammals feel pain, Key claims that fish lack the mammalian neural mechanisms underlying pain and are unconscious of their experiences. Consequently, we do not need to be overly concerned about fishing practices that would otherwise be viewed as painful. Key uses a flawed anthropomorphic lens. All attributions of mental events to organisms other than oneself involve inferences derived from anthropomorphic processes through which we process physiological and behavioral …

Mate Preferences Among Young People: Us And China., Ginny Q. Zhan

Faculty Articles

Mate preferences expressed by college students may reflect both the society’s traditional beliefs and the changing nature of cultural values. The current study compared American and Chinese college students’ responses on mate preference choices (N=545). Results show both similarities and differences in mate preferences between these two groups. Out of 18 characteristics, the two groups were similar in eight and differed in ten; and out of 13 rank order ratings, the two groups differed significantly on ten items. Overall, these findings suggest that while there is evidence of convergence in American and Chinese college students’ mate preference values, reflecting the …

Burnout In Firefighters: A Word On Methodology, Irvin Sam Schonfeld, Renzo Bianchi

Publications and Research

At least three methodological problems affect the study by Katsavouni et al. (2016). First, there are currently no diagnostic criteria for burnout, neither in the DSM-5, nor in the ICD-10. Second, one extremely important variable was omitted from this study of firefighters, namely, depression. Third, the authors did not control for relevant nonoccupational factors such as stressors occurring outside of work.

An Examination Of The Technical And Relational Hypotheses Of Motivational Interviewing In A Sample Of African American Adolescent Girls Seeking Obesity Treatment, Rachel L. Boutte

Theses and Dissertations

Adolescent obesity has increased exponentially over the past three decades in the United States. In response, behavioral interventions have been developed and implemented to address this epidemic; however, treatment adherence is often suboptimal. Motivational interviewing (MI) is a directive, person centered approach to reducing patient ambivalence about change, which has been shown to increase engagement in obesity interventions. The current study investigated the underlying process of MI by exploring two different, but related pathways that explain how change happens (e.g., the technical and relational hypotheses) in the context of a multidisciplinary obesity intervention with African American adolescent girls (N …

Heterogeneous Versus Homogeneous Measures: A Meta-Analysis Of Predictive Efficacy, Suzanne Lee Dean

Browse all Theses and Dissertations

A meta-analysis was conducted to compare the predictive validity and adverse impact of homogeneous and heterogeneous predictors on objective and subjective criteria for different sales roles. Because job performance is a dynamic and complex construct, I hypothesized that equally complex, heterogeneous predictors would have stronger correlations with objective and subjective criteria than homogeneous predictors. Forty-seven independent validation studies (N = 3,378) qualified for inclusion in this study. In general, heterogeneous predictors did not demonstrate significantly stronger correlations with the performance criteria than homogeneous predictors. Notably, heterogeneous predictors did not demonstrate adverse impact on protected classes. One noteworthy finding was that …

Changes In State Suspicion Across Time: An Examination Of Dynamic Effects, Steve Khazon

Browse all Theses and Dissertations

State Information Technology (IT) suspicion is the simultaneous action of uncertainty, mal-intent, and cognitive activity about underlying information that is being electronically generated, collated, sent, analyzed, or implemented by an external agent (Bobko, Barelka, & Hirshfield, 2014). Understanding IT suspicion is important in both military and civilian contexts as both are growing increasingly reliant on automation to augment human performance (e.g., Lenhart, Purcell, Smith, & Zickuhr, 2010). The current process model of state IT suspicion describes how suspicion arises and its immediate correlates. Little is known about how suspicion changes over time and what factors influence this change. Drawing upon …

Stop With The Questions Already! The Effects Of Questionnaire Length And Monetary Incentives On Insufficient Effort Responding., Anthony Gibson

Browse all Theses and Dissertations

Insufficient Effort Responding (IER) can negatively impact self-report data quality. The purpose of the current study was to investigate questionnaire length as a predictor of IER and to examine whether the presence of a monetary incentive moderates the relationship between questionnaire length and IER. I predicted that participants who were assigned to complete longer questionnaires would engage in more IER than would respondents who were assigned to complete shorter questionnaires. I predicted that the effects of questionnaire length on IER would be minimized by the presence of a monetary incentive to respond carefully. Using a sample of undergraduate students (N …

Identification And Examination Of Key Components Of Active Learning, Darrell Scott Kelly

Browse all Theses and Dissertations

The purpose of this study was to examine key components of active learning. I hypothesized that feedback, accountability, and guided exploration were key components of active learning. I collected survey data from second year medical students (N = 103) in three different active learning interventions: peer instruction (PI), team-based learning (TBL), and problem-based learning (PBL), at six time points. My results did not consistently support my hypotheses. However, I observed a pattern of differences concerning feedback and accountability in the predicted direction in all three interventions. Feedback had a positive effect on professionalism in both PI and PBL, and accountability …

Cognition Of Shared Decision Making: The Case Of Multiple Sclerosis, Katherine Domjan Lippa

Browse all Theses and Dissertations

The increasing emphasis in the medical community on shared decision making and patient centered care suggests that patients play a role in their care, but research on clinical reasoning almost exclusively addresses practitioner cognition. As patient involvement increases, it is important to understand the effect patients have on clinical cognition. This necessitates moving beyond a model that equates clinical cognition with practitioner cognition to incorporate the influence of patient cognition and dyadic patient-practitioner cognition. In this dissertation, I suggest that patient-practitioner interactions constitute a distributed cognitive system. As a result patient cognition and the nature of the interaction inherently contribute …

Interaction Of Top-Down And Bottom-Up Search With Magnocellular- And Parvocellular-Mediated Stimuli, James Samuel Garrett

Browse all Theses and Dissertations

The current study simultaneously examined the potentiality of a magnocellular attentional advantage and the competition between top-down and bottom-up processing on attention during visual search as measured by covert and overt visual attention. Specifically, the study tested two opposing views of the competition between top-down and bottom-up processing. The contingent involuntary orienting hypothesis (Folk, Remington, & Johnston, 1992), states that goal directed search is not affected by target-irrelevant stimuli. In contrast, the distractor interference paradigm (Theeuwes, 1994), states that goal directed search can be affected by target-irrelevant stimuli if more salient than the rest of the search array. The study …

A Bifactor Model Of Burnout? An Item Response Theory Analysis Of The Maslach Burnout Inventory - Human Services Survey, David Andrew Periard

Browse all Theses and Dissertations

Burnout is a syndrome-composed of emotional exhaustion, depersonalization, and personal accomplishment-resulting from chronic stress. The Maslach Burnout Inventory - Human Services Survey (MBI-HSS; Maslach, Jackson, & Leiter, 1996) is the most popular measure of burnout. Unfortunately, the MBI-HSS has flaws including highly correlated traits and low subscale reliabilities. I tested a bifactor model for the MBI-HSS based on the work by Meszaros, Adam, Svabo, Szigeti, and Urban (2014) using item response theory. Bifactor models specify a general factor that underlies all the items within a scale and specific factors that underlie the subscale items; also, all factors are orthogonal. I …

Browse all Theses and Dissertations

The Internet has become a platform that many users, governments, corporations, and other organizations hope to leverage in order to support a dynamic and effective physician-patient partnership. However, many researchers have identified significant shortcomings with the current online health information domain. This research examined the use of online health information technology (HIT) by individuals with and without visual disabilities. Two studies were conducted to understand online health information searching behaviors of individuals with and without disabilities. The impact of providing relevant search keywords to participants, and the impact of stress appraisals upon health information search behavior and HIT website usage …

The Influence Of Implicit And Explicit Gender Bias On Grading, And The Effectiveness Of Rubrics For Reducing Bias, Sarah Marie Jackson

Browse all Theses and Dissertations

The effect of implicit bias on discriminatory grading in education has received considerable attention but, to date, no study has examined the effectiveness of using a rubric to reduce biased grading. Current research has demonstrated that the presence of a gender-normative name is sufficient to activate implicit gender bias, which can result in disparate treatment. The purpose of this study was to examine the effects of implicit and explicit gender bias on grading decisions for written assignments. When grading identical essays on the topic of computers (stereotypically-male), participants assigned significantly lower grades when the essay was supposedly written by a …

East-West Cultural Differences In Visual Attention Tasks: Identifying Multiple Mechanisms And Developing A Predictive Model, Yin Yin Tan

Dissertations, Master's Theses and Master's Reports

Past research has identified East-West differences in visual attention associated with holistic versus analytic perception and reasoning strategies (Nisbett et al., 2001; Boduroglu et al., 2009). These cross-cultural differences might stem from several different mechanisms, which may include: interference suppression, response inhibition, attention to detail vs. object configuration, stimulus centrality vs. eccentricity, number of visual distractors (e.g., display set size or clutter), and others.

Although research has shown East-West differences, the results sometimes appear inconsistent with each other, or they lack clear predictions from underlying theories. For example, evidence of a preference for cluttered displays (Wang et al., 2012), evidence …

Designing Better Symbols: An Attentional Approach To Match Symbols To Performance Goals, Hannah North

Dissertations, Master's Theses and Master's Reports

Effective displays require symbol sets that are customized to specific tasks and performance goals. In order to create such sets, designers must account for the effects of top-down and bottom-up attention. The current work presents a pair of experiments that examined the effects of salience and cueing in a change detection tasks within the flicker paradigm (Rensink, O’Regan and Clark, 1997). Each trial, participants either received no cue or a cue indicating which symbol would be the target. This cueing manipulation isolated top-down effects to the cued condition. Consistent with previous studies (Orchard, 2012; Steelman, Orchard, Fletcher, Cockshell, Williamson & …

The Effect Of Inversion And Motor Expertise On Body Compatibility, Harrison M. Goodall Iii

Pomona Senior Theses

Previous studies have established that when a subject’s attention is directed to a specific body part, the subject is able to move that body part faster than a body part their attention was not drawn to. This is known as the body compatibility effect, and it has been shown that this effect only occurs when viewing upright images of the human body. In this study, we presented control subjects and expert acrobats with inverted and upright stimuli. We hypothesized that the amount of time the acrobats spent inverted would result in the acrobats exhibiting body compatibility effects for both upright …
