The Complexities Of Female Sexuality: Narratives Of Women Who Have Experienced Both Heterosexual And Same-Sex Marriages, Krista Anne Butland

Walden Dissertations and Doctoral Studies

Due to social stigma, millions of sexual minorities have concealed their true sexual identities by entering into heterosexual relationships and marriages. Eventually, some transition to same-sex relationships and are able to live authentic lives. This latter group had identified as genuinely heterosexual, never questioning their sexuality until a particular time in their lives when same-sex desires spontaneously appeared. The experiences of transitioning from heterosexual to same-sex partners are not well known, particularly for women who have been legally married to both men and women. Diamond's dynamical systems theory for same-sex sexuality and McCarn and Fassinger's lesbian identity formation model provided …

Mortality Salience Effects On Gender Stereotype Attitudes And Sexism, And The Moderating Effect Of Gender Role Conflicts, Gary Evan Leka

Walden Dissertations and Doctoral Studies

Research on existential mortality fears has indicated that death reminders impact individuals at the cognitive and behavioral levels. One way people cope with this threat is through cherishing cultural values that provide life with meaning. However, little research has explored how death reminders impact cultural standards regarding gender. These cultural values often manifest through various means by male and female groups. Guided by terror management theory, which posits that people address threats to their existence by engaging in culturally-sanctioned behaviors to enhance their self-esteem, the purpose of this study was to examine the effect of mortality salience (MS) on male …

Why Some Women Eat Too Much: A Qualitative Study Of Food-Dependent Women, Gigi Van Ostrand

Walden Dissertations and Doctoral Studies

Obesity has become a worldwide epidemic and limiting one's food intake, or dieting, is usually unsuccessful. The purpose of the study was to explore the effect of food addiction (FA) on the current clinical and behavioral epidemic of obesity. FA, synonymous with food-dependency, is tentatively defined as an eating disorder based on substance dependence, as defined by the Diagnostic and Statistical Manual of Mental Disorders. Measurement of FA has been operationalized by the Yale Food Addiction Scale (YFAS) by applying the diagnostic criteria of substance dependence to eating behaviors. This study was based on the biological theory of chemical addiction …

Moderating Effect Of Psychological Hardiness On The Relationship Between Occupational Stress And Self-Efficacy Among Georgia School Psychologists, Jennifer B. Crosson

Walden Dissertations and Doctoral Studies

School psychologists have unique advisory, consultative, interventional, and therapeutic leadership functions within schools. Consequently, they are confronted with increased levels of occupational stress, which test their cognitive appraisal, coping mechanisms, and feelings of self-efficacy. Although studies have included school psychologists, none have examined the moderating effect of psychological hardiness on the relationship between occupational stress and self-efficacy. A cross-sectional, nonexperimental, and quantitative design used convenience, single-stage, and self-administered web-based surveys with 112 Georgia school psychologists. Using a framework structured by the theory of psychological hardiness, self-efficacy theory, and transactional model of stress and coping, sequential multiple linear regression revealed that …

The March of Dimes indicated that the leading causes of infant mortality include birth defects, preterm birth, low birth weight, sudden infant death syndrome, maternal complications of pregnancy, and respiratory distress syndrome, most of which are considered preventable with access to adequate prenatal care by mothers. The goal of this study was to examine the association between maternal health literacy levels and preterm birth. This research was based on the theoretical framework of the Interaction Model of Client Health Behavior. The hypothesis for this …

Predictors Of Physician Use Of The New Nia Alzheimer's Assessment Protocols, Richard Norman Schultz

Walden Dissertations and Doctoral Studies

Consensus is lacking on early diagnostic criteria and the exact symptoms of Alzheimer's disease (AD). A new, in-office test may help physicians detect the early symptoms of AD, based upon new National Institute of Aging (NIA) criteria. However, a gap exists in knowledge regarding physicians' current use or intent to use the new protocols. Choreographing the descriptive AD terminology in the Diagnostic and Statistical Manual of Mental Disorders IV-TR and the International Classification of Diseases (ICD-10) is recommended. Thus, the purpose of this study was to understand possible contributing factors to physician's use or intent to use of the new …

The Effects Of Motivational Interviewing With The Dual Diagnosis Population, Martina S. Moore

Walden Dissertations and Doctoral Studies

Dual diagnosis clients continue to have low treatment completion rates. The purpose of the current study was to understand if motivational interviewing helped to increase completion rates for clients receiving cognitive behavioral therapy (CBT). Studying the problem was necessary for identifying an evidenced-based model for mental health counselors to help clients with dual diagnoses complete CBT treatment. There were no studies available for understanding the effectiveness of motivational interviewing as a tool for improving treatment completion rates for dual diagnoses clients in intensive outpatient programs. The research question examined if motivational interviewing was effective for improving treatment completion rates for …

Transgender Identity Development In A Rural Area: A Multiple Case Study, Nicholaus Lee Erber

Walden Dissertations and Doctoral Studies

A transgender person develops an identity over time and must overcome several obstacles such as stigma, transphobia, discrimination, and sexism, which can be even more difficult for transgender people who choose to come out and transition in a rural area. Grounded in queer theory, social constructivism, and rural identity development theory, the purpose of this qualitative multiple case study was to explore the lived experiences of 4 transgender persons who came out and transitioned in a rural area, and who accessed online communities as a source of information during their identity development. A 4-stage process was used to collect data, …

The Impact Of A Nonpublic Schools Early Childhood Development Program On Readiness Achievement, Catina Pierre

The impact of a local early childhood program on student school readiness was unknown at the study elementary school. The purpose of this quantitative study was to compare the academic readiness between kindergarten students who participated in the Nonpublic School Early Childhood Development Program and those who did not. The theoretical framework was based on Bruner's constructivist theory of scaffolding, which highlights the importance of providing support to students in the initial stages of learning. Early achievement data from a …

Facilitating Weight Tolerance Among Health And Fitness Majors Toward Obese Persons, Stephanie Boss

Walden Dissertations and Doctoral Studies

Weight bias exists in some health-related degree programs. Overweight and obese persons who experience weight bias in health-related services often delay or avoid medical attention altogether. Guided by the attribution theory, the purpose of this sequential explanatory study was to examine weight bias among health majors at a southwest regional university to illuminate how attitudes can affect the level of care provided to overweight persons. The Attitudes toward Obese Persons (ATOP) scores from a convenience sample of 184 health majors revealed that participants' scores were found to be significantly lower than the midpoint (60) of the ATOP scale, M = …

The Effect Of A State Legitimation Process On Child Support Payments And Father-Child Relationships, Chalonda L. Smith

Walden Dissertations and Doctoral Studies

For noncustodial fathers, having legal rights and leaving an inheritance to their child or children are important aspects of being an active father. Georgia state law sees a difference between paternity and legitimation, and for some noncustodial fathers, although paternity is established and they are responsible for supporting that child financially and medically as deemed through child support enforcement, they have no legal rights to their children, nor can they petition the courts for visitation until legitimation is established. This correlational study examined the impact that the legitimation policy has on noncustodial fathers and their relationship with their child, as …

Guided by resilience theory, the purpose of this study was to examine the relationship between HIV risk behavior and resiliency with the goal of identifying a new intervention to mitigate the HIV infection rate in the BMSM community. The theoretical framework used for this study was the resilience theory. This theory is concern with the phenomenon of …

Best Predictors Of A Person's Long-Term Success With Quitting Tobacco, Nhu-Tam P. Villar

Walden Dissertations and Doctoral Studies

Smoking relapse rates among tobacco users remain high after quit attempts, with or without interventions. Though researchers have examined stress-related factors contributing to high relapse rate, little empirical research has concentrated on variables predicting long-term quit maintenance. The purpose of this study was to determine the predictability of stress management tools, including exercise motivation, eating behaviors, social support, and self-compassion, as well as the significant combined variance of these variables, in a person's long-term maintenance with tobacco use abstinence. Bandura's social cognitive theory was used to highlight the factors contributing to health behavior such as tobacco use. This study involved …

Correlations Between Childhood Obesity And Obesogenic Environmental Variables Within Durham County, North Carolina, Eureka Capri Daye

Walden Dissertations and Doctoral Studies

The application of geographic information systems was used to map obesogenic conditions by zip code tabulation areas in Durham County, North Carolina and evaluated associations between those conditions and the understudied area of early childhood obesity. Of the thirty one percent of the children in Durham County, North Carolina who were considered obese in 2010, four hundred and thirty three (1:5) 2 - 4 year old children who received supplemental nutrition services for women, infants and children were obese with BMI levels greater or equal to the 95th percentile and were used as the criterion variable in the study (N=433). …

The Relationship Between Compassion Fatigue And Self-Transcendence Among Inpatient Hospice Nurses, Donna Marie Johnson

Walden Dissertations and Doctoral Studies

Health care complexities have limited the understanding of nursing care and have jeopardized the "soft skills" or foundation of caring as the art of nursing. Hospice nurses provide a deeper, more spiritual and complex type of care for critically ill and end-of-life (EOL) patients, which place them at a high risk for compassion fatigue. Using Reed's middle range theory of self-transcendence, the purpose of this project was to examine the relationship between compassion fatigue and self-transcendence among inpatient hospice nurses. A descriptive, correlational research methodology guided this inquiry surveying a convenience sample of 42 inpatient hospice nurses at 4 hospice …

Secure-Base Caregiving And Adult Attachment Development Within The Client-Psychotherapist Relationship, Dennis A. Weeks

Walden Dissertations and Doctoral Studies

Recent studies have shown significant improvements in the attachment security of adult therapy clients during therapy, supporting Bowlby's theory that such improvement can be influenced by secure-base caregiving provided by mentors such as therapists. However, because these studies did not measure the secure-base variable, its relationship to client attachment development remains unknown. The present study is the first to evaluate that relationship by measuring clients' pre and posttherapy attachment security using the Relationship Scales Questionnaire and therapists' secure-base caregiving using the Client Attachment to Therapist and Working Alliance Inventory, Short Form. Of 21 initially insecure client participants, 17 experienced high …

Glioblastoma Multiforme: Geographic Variations In Tumor Size, Treatment Options, And Survival Rate, Susan Rebecca Nohelty

Walden Dissertations and Doctoral Studies

Glioblastoma multiforme (GBM) is a destructive brain cancer that results in death 12 to 15 months after diagnosis. The purpose of this retrospective study was to determine if variations in tumor size at diagnosis, treatment options, and survival rate occur in GBM patients living in urban and rural areas of the United States. Using the behavior model of health services as the theoretical framework, this study used secondary data sets of GBM cases reported from 1988 to 2011 from the Surveillance, Epidemiology, and End Results program.

Restructuring High School Science Curriculum: A Program Evaluation, Cathy Robertson

Walden Dissertations and Doctoral Studies

One rural Midwestern high school discovered a discrepancy among school, state, and national science skill attainment, verified by ACT scores. If students do not acquire vital science skills, they may not perform proficiently on science tests, thus impacting future college options. Inquiry based instruction and constructivism provided the basis for the theoretical framework. This study questioned associations between ACT scores, inquiry science technique usage, and ACT standard usage (Phase 1), and teachers' views on science instruction (Phase 2). This sequential explanatory mixed methods program evaluation included 469 ACT scores, surveys sent to 9 science teachers, and 8 interviews. Phase 1 …

Perceptions Of Role Conflict And Workplace Stress Among Women Working In Two Traditionally Male Professions, Timothy Herley

Walden Dissertations and Doctoral Studies

Role conflict and workplace stress can result in psychological and physical disorders. Research has indicated that societal forces are ingrained concerning how gendered behaviors are manifested in the workplace. However, research has not included women working in male-dominated professions, nor has research examined how stress and role conflict might differ for women in these professions. Understanding the different experiences of women in two distinct professions might illuminate the diversity of experiences in these understudied environments. This quantitative study, based on role-congruity and transactional stress theories, examined and compared women's perceptions of role conflict and stress in 2 male-dominated professions. A …

Interpersonal Safety Of Active Duty Women In The Deployed Environment Of Bagram Afghanistan, Cynthia Tara Ferguson

Walden Dissertations and Doctoral Studies

In the United States Armed Forces, 30% of women in the military suffer physical assault each year; in 2009, there were 22 reported cases of sexual assault in the U.S. Central Command. Aggravated assault, gang violence, sexual assault, homicide, and suicide can damage the morale of military personnel at a deployed site and collectively cost millions of dollars over time. Interpersonal violence in the United States military is destructive to the military system and directly diminishes mission readiness. This study was designed to illuminate the environmental, cultural, and political influences that affect interpersonal safety among military women in the deployed …

The Creation Of A Pacemaker Clinic At A Federally-Funded Patient-Centered Medical Home: A Quality Improvement Project, Tony Anno

Walden Dissertations and Doctoral Studies

It is common for clinicians to implant medical devices, such as permanent pacemakers and implantable defibrillators, for cardiac diseases. These medical devices require follow-up care at regular intervals to ensure proper device function and optimal outcomes. Currently, many individuals without insurance or financial resources lack access to recommended follow-up care after implantation of a cardiac device. The purpose of this project was to determine the number of individuals who have had a medical device implanted without insurance coverage over a 3-year period, and then to establish a clinic that provides this service. The standard of care and operating procedure for …

Predictors Of Recidivism For Offenders With Mental Illness And Substance Use Disorders, Linda Buckmon

Walden Dissertations and Doctoral Studies

Mental illness and substance use disorders have been determined to be leading predictors for recidivism among criminal offenders in the United States who are released to community supervision. Women make up an increasing in percentage of this criminal justice population; however, few studies have explored the role that gender plays in determining men and women's recidivism. Offender's education, employment, and peer association have also been reported to be predictors increasing the likelihood of recidivism among criminal offenders. This study was designed to determine if gender, mental illness, substance use disorder, employment, education, and peer association predicted recidivism. Differential association theory …

Integrating Molecular And Traditional Systematic Techniques To Redefine Red Algal (Rhodophyte) Diversity In The Bermuda Islands, Thea Ruth Popolizio

Open Access Dissertations

Molecular-assisted alpha taxonomy (MAAT) is a groundbreaking methodology that combines molecular tools with traditional morphological investigations. From studies using these methods, researchers can determine whether specimens with different morphologies are actually one entity exhibiting high phenotypic plasticity or are multiple genetic species with convergent morphologies, an important breakthrough for phycologists since algae are notoriously difficult to identify on morphology alone. Molecular-assisted techniques have also significantly increased the rate of novel species discovery among the algae, especially rhodophytes. From our own biodiversity assessments, we have learned that numerous members of Bermuda’s macroalgal flora have been misnamed, overlooked, or have not been …

Synchrony Capture Filterbank (Scfb): Auditory-Inspired Signal Processing For Frequency Tracking, Vijay Kumar Peddinti

Open Access Dissertations

The mammalian auditory system is a more robust and versatile sound analyzer than any artificial system that has been developed to date. Nature found a simple yet elegant solution for the hearing mechanism. Incorporating some key aspects of the functional organization of the mammalian auditory system into artificial signal-processing systems may drastically simplify problems of auditory representation and scene analysis such that capabilities for acoustic signal separation, detection, classification, recognition and identification can be greatly improved.

The objective of the thesis is to mimic the functionality of the mammalian peripheral auditory system in a digital computer by developing a synchrony …

Biological Evaluation Of Membrane-Active Compounds As Treatment For Clostridium Difficile Infection, Md Zahidul Alam

Biology Dissertations - Archive

Clostridium difficile infection (CDI), which is caused by a spore-forming, gram-positive anaerobe, named C. difficile, is the leading cause of the hospital-acquired antibiotic-associated diarrhea. Hospitalized elderly patients, who receive broad-spectrum antibiotics, are mostly affected. However, recent clinical observations demonstrate that the incidence of CDI is also increasing in the community and occurs without previously established risk factors. With the recent emergence of epidemic strains of C. difficile, such as BI/NAP1/027, the severity of the CDI has increased in the North America, as well as in other parts of the world. The US Centers for Disease Control and Prevention (CDC), in …

Proximate Behavioral And Morphological Mechanisms That May Mediate Intraguild Predation Stability In The Anisoptera, Benjamin Thomas Allen

Biology Dissertations - Archive

Intraguild Predation (IGP) is a form of interference competition characterized by an intraguild predator consuming interspecific competitors, the intraguild prey. This interaction is extremely common in nature, but mechanistic and descriptive models usually predict that it is unstable with either the IG prey or IG predator becoming locally extinct, dependent on initial conditions. Only intermediate shared prey availability leads to IGP stability in these models, and this condition is not common. In this work, I used dragonfly nymphs to examine behavioral and morphological aspects of consumptive competition and predator avoidance that may act to stabilize IGP, particularly in systems with …
