Priests' Perceptions Of The Leadership Styles Of U.S. Catholic Bishops, Aloysius Okey Ndeanaefo

Walden Dissertations and Doctoral Studies

The United States Catholic bishops have used their authority to address the child sexual abuse scandal, but it has been problematic that no one has yet evaluated their exercised leadership styles. In this phenomenological study, I explored U.S Catholic priests' perceptions of the bishops' leadership styles related to how they handled the child sexual abuse scandal. Knowing the bishops' leadership styles was paramount to fill the research gap. The theoretical frameworks underpinning this study were transformational leadership, transactional leadership, charismatic leadership, and servant leadership. Data collected through interviews with 11 Catholic priests revealed their perceptions of how the behavioral characteristics …

A Phenomenological Analysis Of Formerly Incarcerated Women's Perceptions Of Successful Reentry, Angela Martilik

Walden Dissertations and Doctoral Studies

Female offenders are distinctly different from male offenders, and present with their own gender-specific needs and issues both in and out of the correctional setting. Most approaches to treatment and programming for female offenders are currently based on research involving males and approaches designed for males. Inquiry regarding the gender-specific needs of female inmates as they pertain to treatment and reentry programs is necessary so professionals can better understand how to serve this population. Through in-depth semi-structured interviews with 8 women who were formerly incarcerated in the United States, this phenomenological study was used to examine the perceptions of successful …

High School Teachers' Self-Reported Knowledge And Implementation Of Social And Emotional Learning Competencies, Stephanie Y. Clark Rhoe

Walden Dissertations and Doctoral Studies

Public policymakers have failed to address public high school students' social and emotional learning (SEL). Recent public policies such as Common Core State Standards (CCSS) do not measure SEL outcomes as significant. Public education is government funded and therefore public policy driven. Research indicates SEL competencies have a positive influence on students' academic successes, classroom behaviors, and future career outcomes. The conceptual framework for this study was based on SEL components described by the Collaborative for Academic, Social, and Emotional Learning (CASEL) and served as the lens though which the data were analyzed. Research questions for this phenomenological study explored …

Public Elementary School Teachers' Experiences With Implementing Outdoor Classrooms, Lori Schultz Goff

Walden Dissertations and Doctoral Studies

Children experience limited time outdoors and have few opportunities for outdoor learning in schools, putting them at risk for being unprepared to engage in solving environmental and societal problems. Researchers have examined outdoor learning at the preschool and high school levels; elementary school experiences have been explored less frequently. Guided by a conceptual framework informed by social emotional learning (SEL), ecological literacy, and teacher self-efficacy, this study investigated public school elementary teachers' experiences with outdoor classrooms including barriers and supports to creating and using outdoor classrooms. A qualitative design using in-depth interviews with interpretive phenomenological analysis techniques was conducted with …

Thinking Perspective Profiles As A Predictor Of Intelligence Analysts' Job Performance., Curtis Rasmussen

Walden Dissertations and Doctoral Studies

Empirical research has supported the use of general cognitive ability to predict employee performance; however, studies have accounted for only a fraction of the variance. The current study addressed whether intellectual styles, which describe how individuals habitually acquire and use information, account for a significant portion of the variance in job performance not covered by general cognitive ability. The study followed a quantitative, nonexperimental design with a convenience sample of 77 intelligence analysts from 6 U.S. government agencies and 2 online professional groups. MindTime provided the primary theoretical framework. The International Cognitive Ability Resource, MindTime Profile InventoryTM, and Self-Rated Analytic …

Social-Sexual Autonomy, Person-Centered Planning, And Individuals With Intellectual Disabilities, Earlie Simone Brown-Hall

Walden Dissertations and Doctoral Studies

Abstract

Sexual autonomy is the right and capacity of each individual to decide and make choices

about whom, when, and how they express themselves sexually. Individuals with

intellectual disabilities have frequently been marginalized, oppressed, and left out of

discussions about sexuality placing them at risk of abuse, unsafe sex practices, and

unplanned pregnancies. The purpose of this qualitative study was to examine the

usefulness of person-centered planning techniques in the development of an individual

service plan that address the social-sexual needs of individuals with intellectual

disabilities. Purposeful sampling was used to select 8 participants for this study. Specific

participants were …

Impact Of The Centering Pregnancy Model On Sustaining Normal Gestation Weight Gain, Hyacinth Dennis-Crooks

Walden Dissertations and Doctoral Studies

Obesity during pregnancy has increased in prevalence over the last decade and is associated with adverse outcomes for mothers and babies, especially Black mothers. In the local setting of this project, the group-centered centering pregnancy model (CPM) was implemented to improve outcomes of pregnancy. The model had not been evaluated for its effectiveness in reducing weight in Black pregnant women; therefore, there was a need for an evaluation of the effectiveness of the CPM in decreasing excessive gestational weight gain (EGWG). The health belief model was used to guide the project, which compared mothers' weights early in the 2nd trimester, …

Health Seeking Behavior In African American Women, Lorretta Larmond-Hyman

Walden Dissertations and Doctoral Studies

Disparities exist in the health-seeking behavior of African American (AA) women in the United States. Specifically, AA women 40 years and older often do not adhere to guidelines for breast cancer screening because of demographic and socioeconomic factors that have impacted health disparities. The purpose of this study was to research negative health-seeking behavior toward early-stage breast cancer detection in AA women 40 years and older. The main research questions addressed whether there is a relationship between negative health-seeking behavior, operationally defined as lack of a personal doctor, lack of health insurance, and lack of doctor visits within the past …

Using A Quality Workbook Committee To Improve Nurse-Sensitive Patient Indicator Scores, Nicole Robinson

Walden Dissertations and Doctoral Studies

Health care providers gather and track quality patient indicator scores to monitor patients' safety and outcomes and decrease the number of adverse events. Nursing leaders implemented a Quality Workbook Committee (QWC) within a hospital setting to improve patient outcomes and the facility's reported scores for nurse-sensitive patient indicators. The practice-focused question for this quality improvement evaluation project examined whether the implementation of the QWC improved nurse-sensitive patient indicator scores. Watson's theory of human caring was used to evaluate the gap in practice, and Rosswurm and Larabee's model for evidence-based practice change provided guidance for planning the project. Sources of evidence …

Theses and Dissertations--Public Health (M.P.H. & Dr.P.H.)

Background

The rabies virus is a zoonotic pathogen that is nearly 100 percent fatal once symptoms occur. Because it is still active in wildlife populations in Kentucky, the need for preventive measures and surveillance is critical. Temperature and precipitation have been shown to affect rabies. This study examined rabies submissions in Kentucky, weather and geographical distribution to both describe and predict cases.

Methods

Data from the University of Kentucky Veterinary Diagnostics laboratory were used to assess rabies submissions from 2005 through 2015. These submissions were anonymously submitted by the public and the Florescent Antibody Test was used to determine infection …

Development And Characterization Of A Paper Based Analytical Device For Heparin Quantification, Carolanne Norris

Undergraduate Honors Thesis Projects

Paper-based analytical devices (PAD) have gained popularity in the past ten to fifteen years due to many favorable mechanical properties.1 They have largely been used to analyze small ionic species, such as Na+ and Li+, but little research has been done on their capability of to analyze large polyionic species, for instance the highly sulfonated polysaccharide heparin.2,3 This study explores adaptation of a traditional optode design to a low cost PAD that employs a smartphone as a detector. Throughout the study variables, such as membrane composition, pH, volume of solution, time, addition of a polymer, use of different cell phone …

Predictors Of Nutritional Counseling Among Adolescents By Physicians In California, Jean Kigozi

Walden Dissertations and Doctoral Studies

The prevalence of obesity in the United States was stable at 17% from 2011-2014 among approximately 13 million children and adolescents 12-19 years of age, according to the Centers for Disease Control and Prevention. Nutritional counseling has been recommended, and while most physicians agree that it is necessary, it is not happening consistently. The purpose of this study was to examine the association between dietary intake, physical activity, and body mass index (BMI) characteristics of youth 12-17 years old in California and the receipt of nutritional counseling. Social cognitive theory guided this quantitative cross-sectional analysis of archived data from 814 …

Confronting Heteronormative Standards Of The Nuclear Family: A Narrative Analysis Of Transgender Dads Pregnancy And Birth Experiences, Annie Rosenblum

Theses & ETDs

In our society, we most commonly associate pregnancy and birth with the bodies and experiences of cisgender, straight women. This thesis seeks to center the underrepresented pregnancy and birth stories of transgender dads through a narrative analysis of their experiences, as told by them in media. Their stories are sourced from three pieces of media created by and for transgender parents (and those wanting to learn more about them): Labor of Love (2008), a memoir, The Accidental Gay Parents (2015-2017), a podcast, and Transgender Parents (2014), a documentary. I will broadly explore how gender determines reproductive choices, and more specifically …

The Effect Of Mosquito Ditching On Carbon Sequestration In Mangrove Ecosystems And Associated Management Implications, Race Stryker

Theses & ETDs

Mangroves are coastal wetlands that are critical to the global carbon cycle. Mangroves account for about 10-15% of the carbon sequestered by forests while only occupying 0.5% of the total forested area on the planet. Many mangrove ecosystems in the state of Florida suffer from the historic impacts of ditches that were created to reduce viable breeding grounds for mosquitoes. Unfortunately, the full effects of these ditches on rates of carbon sequestration have yet to be investigated or understood. This thesis presents an exploration of the policies that lead to mosquito ditching in Florida; provides an assessment of the impacts …

Continuity Of Transcriptomes Among Colorectal Cancer Subtypes Based On Meta-Analysis, Siyuan Ma, Shuji Ogino, Princy Parsana, Reiko Nishihara, Zhirong Qian, Jeanne Shen, Kosuke Mima, Yohei Masugi, Yin Cao, Jonathan A. Nowak, Kaori Shima, Yujin Hoshida, Edward L. Giovannucci, Manish K. Gala, Andrew T. Chan, Charles S. Fuchs, Giovanni Parmigiani, Curtis Huttenhower, Levi Waldron

Publications and Research

Background: Previous approaches to defining subtypes of colorectal carcinoma (CRC) and other cancers based on transcriptomes have assumed the existence of discrete subtypes. We analyze gene expression patterns of colorectal tumors from a large number of patients to test this assumption and propose an approach to identify potentially a continuum of subtypes that are present across independent studies and cohorts.

Results: We examine the assumption of discrete CRC subtypes by integrating 18 published gene expression datasets and >3700 patients, and contrary to previous reports, find no evidence to support the existence of discrete transcriptional subtypes. Using a meta-analysis approach to …

A Structured Weight Loss Program To Combat Obesity In Women, Tara English

Walden Dissertations and Doctoral Studies

Rates of obesity and the associated comorbidities continue to increase for women in the United States. Despite information available, efforts at weight loss are often unsuccessful because women lack integral knowledge of how to approach the various components essential for weight loss. This doctoral project was created to address the practice question of whether obesity can be reduced through a step-wise weight loss program that identifies essential elements to reduce weight in menopausal age women. Guided by the information-motivation-behavioral skills model, this project led 17 volunteer participants from a Northwest, Florida primary care clinic through 6 weeks of protocols supplemented …

Abundance Data Change Geographic Estimates Of Terrestrial Invasive Plant Risk In The Contiguous United States, Mitchell W. O'Neill

Master's Theses and Capstones

Invasive plants pose severe threats to ecosystems worldwide. Geographic invasion risk is often assessed using occurrence-based species distribution modeling, which estimates where species can occur but cannot represent variation in abundance, a crucial component of impact. I assembled an ordinal abundance dataset for 155 terrestrial invasive plant species in the contiguous United States based on reports to the Early Detection & Distribution Mapping System, a georeferenced invasive species data repository. I used maximum entropy models to estimate range boundaries and ordinal regression to estimate abundance within ranges. I predicted the areas where establishment is possible (potential establishment ranges), and where …

Metformin Suppresses Retinal Angiogenesis And Inflammation In Vitro And In Vivo, Jing Han, Yue Li, Xiuli Liu, Tongrong Zhou, Haijing Sun, Paul Edwards, Hua Gao, Fu-Shin Yu, Xiaoxi Qiao

Ophthalmology Articles

The oral anti-diabetic drug metformin has been found to reduce cardiovascular complications independent of glycemic control in diabetic patients. However, its role in diabetic retinal microvascular complications is not clear. This study is to investigate the effects of metformin on retinal vascular endothelium and its possible mechanisms, regarding two major pathogenic features of diabetic retinopathy: angiogenesis and inflammation. In human retinal vascular endothelial cell culture, metformin inhibited various steps of angiogenesis including endothelial cell proliferation, migration, and tube formation in a dose-dependent manner. Its anti-angiogenic activity was confirmed in vivo that metformin significantly reduced spontaneous intraretinal neovascularization in a very-low-density …

The Evaluation Of A Breast Cancer Screening Decision Aid In The Community Setting., Kimberly Gibbons

DNP Scholarly Projects

Breast cancer screening (BCS) has been recommended to women by healthcare providers as well as professional organizations and non-profit awareness organizations for over four decades. Recently, attention is being paid to quantification of the actual benefits and harms of BCS with mammography. The harms include overdiagnosis, overtreatment and mandate of mammography screening that may not be in alignment with the individual values and preferences of women ages 40-69. This evidence translation project developed a resource for practice that was evaluated by community participants for alignment with personal value and preference-based educational needs about BCS. This project piloted a clinical practice …

Implementation Of A Physical Activity Group At A Community Mental Health Center: A Pilot Quality Improvement Project To Reduce Depressive Symptoms In Adolescents With Major Depressive Disorder, Nancy Gallagher

DNP Scholarly Projects

Major Depressive Disorder is a debilitating illness that affects millions of Americans, including adolescents. The majority of adolescents with Major Depressive Disorder (MDD) do not receive treatment. There may be a variety of reasons for this including stigma, access to care, and potential adverse reactions. People suffering from MDD are known to be at high risk for suicide. Lack of treatments adds the risk of suicide for adolescents with MDD. Identifying and implementing treatment options that are more acceptable and accessible are of the utmost importance. Although there is limited research regarding exercise/physical activity, depressive symptoms, and adolescents with MDD, …

Implicit Racial Biases In Prosecutorial Summations: Proposing An Integrated Response, Praatika Prasad

Fordham Law Review

Racial bias has evolved from the explicit racism of the Jim Crow era to amore subtle and difficult-to-detect form: implicit racial bias. Implicit racial biases exist unconsciously and include negative racial stereotypes andassociations. Everyone, including actors in the criminal justice system who believe themselves to be fair, possess these biases. Although inaccessible through introspection, implicit biases can easily be triggered through language. When trials involve Black defendants, prosecutors’ summations increasingly include racial themes that could trigger jurors’ implicit biases, lead to the perpetuation of unfair stereotypes, and contribute to racial injustice and disparate outcomes. This Note examines and critiques the …

Reproductive Health And Fertility Among Transgender Adolescents: A Knowledge And Attitudes Survey, Aimee Alphonso

Yale Medicine Thesis Digital Library

The goal of this study was to determine the knowledge and attitudes of transgender adolescents regarding fertility and future parenthood. We developed and administered a cross-sectional questionnaire to a convenience sample of 23 transgender and gender non-conforming adolescents (mean age 16.2 ± 2.6) who attended the Yale Pediatric Gender Program between October 2016 and August 2017. Our results indicate that transgender adolescents have a basic understanding of reproductive health and fertility (mean total knowledge score of 3.78 ± 0.80 out of 5). Knowledge scores were significantly higher in participants with previous information about gender-affirming hormone therapy (GAH; p
