Improving Communication Access With Deaf People Through Nursing Simulation: A Cross-Disciplinary Collaboration, Jamie L. Mccartney Ph.D., Tracy Gidden, Jennifer Biggs, Kathy Geething, Karl Kosko Ph.D.

Journal of Gender, Ethnic, and Cross-Cultural Studies

Baccalaureate nursing and sign language interpreting students participated in a pediatric discharge simulation with a deaf person playing the role of the baby’s parent. At the conclusion of the simulation, participants were emailed a consent letter and a link to a 17-item questionnaire developed by the authors. Responses were analyzed both quantitatively and qualitatively, whereby nonparametric statistics were calculated to examine Likert-scale items. A Mann-Whitney test statistic was calculated, instead of an independent samples t-test, given the smaller sample in the current study (n = 26). A question was posed to participants that evaluated their self-perception of the effectiveness of …


“Handicap Removed”: An Alternative Path To The Social Model, Craig M. Rustici Jun 2023

“Handicap Removed”: An Alternative Path To The Social Model, Craig M. Rustici

Journal of Gender, Ethnic, and Cross-Cultural Studies

This article identifies an expression of a social model of disability in a 1966 film promoting Hofstra University’s Program for the Higher Education of the Handicapped and traces that model back to books published by the pioneering rehabilitation physician Henry H. Kessler in 1935 and 1947, decades before the UPIAS (Union of the Physically Impaired against Segregation) Fundamental Principles of Disability (1976). In light of Kessler’s articulation of social and minority models, identification of contrasting religious, charity and medical models, and discussion of disability stigma, this article reassesses Ruth O’Brien’s critique, in Crippled Justice (2001), of Kessler and the twentieth-century …


Understanding Relationships Between Early Life Toxic Stress, Childhood Socioeconomic Disadvantage, And Allostatic Load In Adolescence, Amanda King Jul 2018

Understanding Relationships Between Early Life Toxic Stress, Childhood Socioeconomic Disadvantage, And Allostatic Load In Adolescence, Amanda King

Dissertations (1934 -)

Chronic disease prevalence among children and adolescents is rising, which is thought to result in part from elevations in allostatic load (AL). AL is the cumulative physiological dysregulation that results from exposure to biological, social and environmental stressors over time. Socioeconomic disparities in chronic disease and AL have been well-documented in adult populations, including links between childhood socioeconomic disadvantage (CSD) and AL, yet little is known as to whether CSD may begin to impact AL earlier in life. Differential exposure and vulnerability to stress among racial/ethnic minorities may increase risk for elevated AL among those experiencing CSD. Framed by the …


The Famous Names Discrimination Task As A Biomarker Of Alzheimer's Disease Risk: An Erp Study, Elizabeth Rose Paitel Apr 2018

The Famous Names Discrimination Task As A Biomarker Of Alzheimer's Disease Risk: An Erp Study, Elizabeth Rose Paitel

Master's Theses (2009 -)

Current ERP research emphasizes age- and pathology-related declines in neural processing in the form of attenuated amplitudes and prolonged latencies. Notably, there is a gap in the ERP literature regarding neural processing trajectories in the time between healthy young adulthood and clinical MCI/AD samples. fMRI research, however, has demonstrated periods of increased, compensatory activation in healthy, cognitively intact APOE ɛ4 carriers both during resting state and event-related tasks (Bondi, Houston, Eyler, & Brown, 2005; Evans et al., 2014; Filippini et al., 2009; Rao et al., 2015), consistent with compensatory theories of cognitive aging (Cabeza, 2002; Park & Reuter-Lorenz, 2009; Reuter-Lorenz …


The Mediating Effects Of Positive Thinking And Social Support On Suicide Resilience Among Undergraduate Students, Denise Marie Matel-Anderson Oct 2017

The Mediating Effects Of Positive Thinking And Social Support On Suicide Resilience Among Undergraduate Students, Denise Marie Matel-Anderson

Dissertations (1934 -)

Suicide has been the 2nd leading cause of death for 18-24-year-olds in the US since 2011. The stress experienced by undergraduate college students has the potential to increase ones’ risk for suicide. Resilience theory was used as a theoretical framework to examine the interplay between risk and protective factors. A cross-sectional and correlational design was used to assess the mediating effects of positive thinking and/or social support on suicide resilience in 131 college students 18-24 years old who completed an online survey. An indirect effect of self-esteem on suicide resilience was found through positive thinking and social support indicating that …


Examining The Durability Of Peers For Adolescents With Asd: Maintenance Of Neurological And Behavioral Effects, Bridget Kathleen Dolan Jul 2017

Examining The Durability Of Peers For Adolescents With Asd: Maintenance Of Neurological And Behavioral Effects, Bridget Kathleen Dolan

Dissertations (1934 -)

To date, there are no known published studies that have assessed the maintenance of treatment effects in the context of neurological changes and their relationship to behavioral outcomes following a social skills intervention for adolescents with Autism Spectrum Disorder (ASD). The few studies that have incorporated long-term assessment into their design have focused exclusively on sustained behavioral responses to treatment. Individuals with ASD across the lifespan exhibit aberrant neural activity, which is thought to underlie social skill deficits noted in persons on the spectrum. Thus, this study sought to examine the impact of a social skills intervention, the Program for …


Aging, Executive Function, Fronto-Parietal Network Cortical Thickness: Insights From Cognitive Reserve, Katherine Reiter Jul 2017

Aging, Executive Function, Fronto-Parietal Network Cortical Thickness: Insights From Cognitive Reserve, Katherine Reiter

Dissertations (1934 -)

Cognitive reserve (CR) indexes the nonlinear relationship between neurological insult and behavioral change. CR is manifested in both static factors (e.g., childhood environment, education) and modifiable lifestyle factors, (e.g., leisure activities). Detailed investigation of the influence of CR on cortical thickness, which indexes neuropathology, and cognitive functioning could be particularly important in understanding the heterogeneity of Alzheimer’s disease (AD). While memory decline is the hallmark of AD, executive functioning (EF) decline often predates memory changes, making EF an important target for investigating CR influences. The current study examines the relationship of CR and genetic risk for AD (ε4) on EF …


Pediatric Oncology Nurses' Experiences With Prognosis-Related Communication, Amy Rose Newman Apr 2017

Pediatric Oncology Nurses' Experiences With Prognosis-Related Communication, Amy Rose Newman

Dissertations (1934 -)

Health care providers (HCPs) in pediatric oncology are faced with the challenge of communicating the devastating news of a cancer diagnosis and prognosis. This type of communication can be referred to as prognosis-related communication (PRC). While the initial conversation with the patient and family regarding prognosis is generally considered the responsibility of the physician, patients and family members will subsequently turn to nurses for clarification of the information presented. If nurses are excluded from initial conversations, they may feel as though they are “working in the dark,” trying to answer questions while not contradicting what the physician said. This strained …


The Cry Of The Poor: Anthropology Of Suffering And Justice In Health Care From A Latin American Liberation Approach, Alexandre Andrade Martins Apr 2017

The Cry Of The Poor: Anthropology Of Suffering And Justice In Health Care From A Latin American Liberation Approach, Alexandre Andrade Martins

Dissertations (1934 -)

This dissertation examines the connection between poverty and health inequalities from a liberation theological ethics perspective. It uses Simone Weil’s and Latin American liberation theology’s approaches to suffering and social justice as theoretical sources to address health inequalities and the suffering of the poor because of social injustice, vulnerability to diseases, and lack of healthcare assistance. First of all, these approaches are examined from how they shape an anthropology of suffering that enable us to understand the suffering of the poor and, at the same time, to recognize them as agents of their own liberation and struggle for justice in …


Objective And Subjective Influences On Cognitive Performance In Adolescents With Type 1 Diabetes, Natalie E. Benjamin Apr 2017

Objective And Subjective Influences On Cognitive Performance In Adolescents With Type 1 Diabetes, Natalie E. Benjamin

Master's Theses (2009 -)

Type 1 diabetes mellitus (T1DM) is an increasingly common chronic illness in children and adolescents that can result in short- and long-term health complications. Disease management can be a particular challenge for adolescents seeking autonomy from caregivers. Recently, there has been a significant increase in adolescents’ use of diabetes-related technology to aid in blood glucose (BG) management and insulin administration. Individuals with T1DM also experience symptoms related to their BG levels, and these symptoms can serve as indicators of out-of-range BG levels and guide management decisions. Although research shows that diabetes-related health factors can affect cognitive functioning, no existing research …


The Relationship Between The Military's Masculine Culture And Service Members' Help-Seeking Behaviors, Rachel Reit Apr 2017

The Relationship Between The Military's Masculine Culture And Service Members' Help-Seeking Behaviors, Rachel Reit

Master's Theses (2009 -)

Since the terrorist attacks on September 11, 2001, over 2.5 million active duty U.S. military service members have deployed to Iraq and Afghanistan (Knobloch & Wilson, 2015). Of those who return as veterans, twenty percent experience serious mental health problems, and only 30-40% of them seek help or treatment (Tanielian & Jaycox, 2008; Wilson, Gettings, Hall, & Pastor, 2015). Recently, the military has increased efforts to encourage help-seeking behaviors among service members and to normalize mental health treatment. However, the military’s masculine culture and emphasis on strength and toughness inhibits the success of these efforts. The present studies investigate the …


Baby Dust To All! Identity Construction In Two-Week Wait Online Discussion Forums, Danielle R. Derose Oct 2016

Baby Dust To All! Identity Construction In Two-Week Wait Online Discussion Forums, Danielle R. Derose

Master's Theses (2009 -)

Women with a self-identified infertility status sometimes choose to address this status by seeking medical intervention. There are a variety of methods available when attempting to conceive using medical treatments, with the choice heavily dependent on the health of each partner. A common first approach by reproductive endocrinologists is that of intrauterine insemination, or IUI. Women undergoing IUI invest significant time and money into the process and often must undergo procedures or take medication that can be enormously distressing. Once the IUI is complete, the woman must wait an emotional two weeks before she finds out if she is pregnant …


Finding Meaning And Sensemaking In Hospital Nursing Teams: The Promise Of Narrative Medicine, Shelley Bobb Oct 2016

Finding Meaning And Sensemaking In Hospital Nursing Teams: The Promise Of Narrative Medicine, Shelley Bobb

Dissertations (1934 -)

Purpose. Narrative medicine is an innovative field that has provided meaning and increased communication between health care providers and their patients. This study explored the significance and nature of the practice of Narrative Medicine and what impact this had with NICU nurses on their team interaction with respect to team functioning, sense-making, and vocational understanding. This study seeks to provide nursing teams another tool to find meaning in their work and strengthen their teamwork. Using Narrative Medicine and the theory of phenomenology, this is a new approach that may bring nurses to draw on fresh ways to engage their work …


Reinforcement Learning, Error-Related Negativity, And Genetic Risk For Alzheimer's Disease, Christina Marie Figueroa Apr 2016

Reinforcement Learning, Error-Related Negativity, And Genetic Risk For Alzheimer's Disease, Christina Marie Figueroa

Dissertations (1934 -)

Reinforcement learning (RL) has been widely used as a model of animal and human learning and decision-making. The neural networks underlying RL involve many of the same structures primarily affected by Alzheimer’s disease (AD) such as the hippocampus. Yet, RL and non-invasive evaluation of its neural underpinnings have been underutilized as a framework for understanding disease pathology and its pre-clinical states. This study aimed to provide a novel approach for assessing subtle changes in asymptomatic apolipoprotein-E (APOE) carriers and non-carriers. Electroencephalography was collected from forty APOE genotyped older adults (Male n = 11; Mage = 79.30; Meducation = 14.88 years) …


A Mobile Health Approach To Assist Veterans Reintegrating Into Civilian Life, Rizwana Rizia Apr 2016

A Mobile Health Approach To Assist Veterans Reintegrating Into Civilian Life, Rizwana Rizia

Dissertations (1934 -)

Civilian reintegration is the process of transitioning from military service to civilian life. For any active or reserve member of armed force, reintegration into civilian life can be very challenging. The reintegration phase has far larger impact than just a change in profession. It is actually a change in every aspect of life, which includes changes in lifestyles, responsibilities, home life, communities and much more. If a veteran is unable to survive the challenges of civilian reintegration it can adversely impact his or her personal and social life. Furthermore, in the long run it may even result in serious psychological …


Video Game Interventions To Improve Cognition In Older Adults, David E. C. Marra Apr 2016

Video Game Interventions To Improve Cognition In Older Adults, David E. C. Marra

Master's Theses (2009 -)

Cognitive abilities decline as part of the normal aging process. Various non-pharmacological interventions are being studied in an effort to ameliorate this cognitive decline. Some of these interventions include computerized cognitive training, such as neuropsychological software (i.e., brain training games) and video games. A previous study in our lab found that older adults who played a brain training game or a video poker game showed similar cognitive gains. The purpose of the present study was to follow the methodological procedures of our previous study to try and determine if the positive effects seen for the brain training program and video …


A Neurobiological Pathway That Mediates Stress-Induced Drug Use, Oliver Vranjkovic Oct 2015

A Neurobiological Pathway That Mediates Stress-Induced Drug Use, Oliver Vranjkovic

Dissertations (1934 -)

Cocaine addiction represents a tremendous health and financial burden on our society and the high rate of relapse to cocaine use in abstinent addicts represents a major barrier to effective therapy. Thus, understanding the factors that contribute to relapse and the underlying neurobiological processes is important for guiding the development of treatment for addiction. Stressful life events often trigger drug use in recovering addicts. The contribution of stress to drug use is problematic due to the unpredictable and often uncontrollable nature of stress. A growing literature indicates that norepinephrine and corticotropin releasing factor (CRF) in the brain play key roles …


Neural Plasticity In Response To Intervention In Adolescents With Autism Spectrum Disorders, Sheryl Jayne Stevens Jul 2015

Neural Plasticity In Response To Intervention In Adolescents With Autism Spectrum Disorders, Sheryl Jayne Stevens

Dissertations (1934 -)

Current theories of Autism Spectrum Disorders (ASD) suggest that they may develop from the transactional interaction between biological risk factors and environmental processes (Dawson et al., 2009). Due to the brain’s experience-expectant nature, one’s degree of social exposure may have a significant impact on their brain development and behavioral presentation. In addition to the primary critical neurodevelopmental period identified in early childhood, recent research has demonstrated a second period of substantial neurodevelopment during the adolescent period (Sisk & Foster, 2004). This study investigated the neural and behavioral impact of participation in an empirically validated behavioral intervention (The Program for the …


Stay-At-Home-Fathers Navigating Depression: A Consensual Qualitative Research Study, William Douglas Meyers Caperton Jul 2015

Stay-At-Home-Fathers Navigating Depression: A Consensual Qualitative Research Study, William Douglas Meyers Caperton

Dissertations (1934 -)

Evidence suggests that the practices through which men are socialized to become masculine may serve both to restrict their potential in ways that lead to psychological distress, and also to restrict the ways in which they respond to such distress (Addis & Mahalik, 2003; Mahalik, Good, Tager, Levant, & Mackowiak, 2012; O’Neil, 2008). While we are beginning to understand masculine depression (Cochran & Rabinowitz, 2000; Magovcevic & Addis, 2008) and paternal depression (Paulson & Bazemore, 2010; Ramachandani & Psychogiou, 2009), almost nothing is known about how SAHFs experience depression, nor their experiences and beliefs regarding help-seeking and psychotherapy. The trend …


Role Of Shared Care In The Relationship Between Depressive Symptoms And Self-Care In Patients With Heart Failure, Susan Cole Jul 2015

Role Of Shared Care In The Relationship Between Depressive Symptoms And Self-Care In Patients With Heart Failure, Susan Cole

Dissertations (1934 -)

Heart failure (HF) is a chronic condition affecting over 5 million Americans. Heart failure accounts for over 32 billion dollars in total cost each year, and is the most common cause of hospitalization for persons 65 years of age or older. Patients with HF experience poor self-care, are at risk for depressive symptoms, and have high rates of 30-day hospital readmissions. Social support influences depressive symptoms, self-care, and hospital readmissions. Shared care was used to operationalize social support. Shared care is a system of three relationship processes communication, decision making, and reciprocity, used to exchange social support. The purpose of …


Interpersonal Communication In The Context Of Dementia: Examining Family Caregivers' Appraisals And Burden, Stacy Lynn Barnes Oct 2014

Interpersonal Communication In The Context Of Dementia: Examining Family Caregivers' Appraisals And Burden, Stacy Lynn Barnes

Dissertations (1934 -)

Purpose and Objectives: The purpose of this study was to explore dementia family caregivers' appraisals of communication behaviors and strategies, and their relationships to caregiver burden. Study objectives were to investigate: 1) the relationship between frequency of dementia-related communication behaviors and caregivers' appraisals of frustration; 2) the relationship between caregivers' use of communication strategies and appraisals of helpfulness; 3) the structural relationships between communication behavior appraisal, communication strategy appraisal, problem behaviors, and caregiver burden; and 4) caregiver education level as a moderating variable of the final structural model. Methods: A written, mailed questionnaire was developed to capture dementia family caregivers' …


Hispanic Mothers' Normative Beliefs And Intentions About The Discussion Of Sex-Related Topics With Their Adolescent Daughters, Dana M. Rodriguez Oct 2014

Hispanic Mothers' Normative Beliefs And Intentions About The Discussion Of Sex-Related Topics With Their Adolescent Daughters, Dana M. Rodriguez

Dissertations (1934 -)

Hispanic adolescent females continue to have rates of pregnancy and STIs, which exceed those of white non-Hispanic peers. When mothers engage in the discussion of sex-related topics (DSRTs) with their adolescent daughters, it has been shown to delay or decrease sexual intercourse. However, it has been found that Hispanic parents talk less with their daughters about sex-related topics (SRTs) when compared to other ethnic groups. Understanding why Hispanic mothers may or may not intend to engage in DSRTs is important in order to design culturally appropriate programs aimed at increasing their DSRTs. A sequential mixed-methods predictive correlational design framed by …


Patient Perceptions Of Patient-Empowering Nurse Behaviours, Patient Activation And Functional Health Status In Postsurgical Patients With Life-Threatening Long-Term Illnesses, Teresa Jerofke-Owen, Marianne E. Weiss, Olga Yakusheva Jun 2014

Patient Perceptions Of Patient-Empowering Nurse Behaviours, Patient Activation And Functional Health Status In Postsurgical Patients With Life-Threatening Long-Term Illnesses, Teresa Jerofke-Owen, Marianne E. Weiss, Olga Yakusheva

College of Nursing Faculty Research and Publications

Aim

To explore the trajectory of associations between the nursing care process of patient empowerment during postsurgical hospitalization and postdischarge patient self-management outcomes, specifically patient activation and functional health status.

Background

Patient-centred care models advocate for patient empowerment in long-term illness care. Postsurgical patients with life-threatening long-term illnesses frequently feel powerless, have unmet needs, decreased functional health status and high readmission rates; however, previous studies of patient empowerment have conceptualized empowerment as an outcome primarily in outpatient settings, with little attention paid to provider processes used to empower patients during hospitalizations.

Design

A non-experimental, prospective, correlational study.

Methods

This sample …


Stressor-Induced Increase In Muscle Fatigability Of Young Men And Women Is Predicted By Strength But Not Voluntary Activation, Manda L. Keller-Ross, Hugo M. Pereira, Jaclyn Pruse, Tejin Yoon, Bonnie A. Schlinder-Delap, Kristy A. Nielson, Sandra Hunter Apr 2014

Stressor-Induced Increase In Muscle Fatigability Of Young Men And Women Is Predicted By Strength But Not Voluntary Activation, Manda L. Keller-Ross, Hugo M. Pereira, Jaclyn Pruse, Tejin Yoon, Bonnie A. Schlinder-Delap, Kristy A. Nielson, Sandra Hunter

Psychology Faculty Research and Publications

This study investigated mechanisms for the stressor-induced changes in muscle fatigability in men and women. Participants performed an isometric-fatiguing contraction at 20% maximal voluntary contraction (MVC) until failure with the elbow flexor muscles. Study one (n = 55; 29 women) involved two experimental sessions: 1) a high-stressor session that required a difficult mental-math task before and during a fatiguing contraction and 2) a control session with no mental math. For some participants (n = 28; 14 women), cortical stimulation was used to examine mechanisms that contributed to muscle fatigability during the high-stressor and control sessions. Study two …


Replication Of Known Dental Characteristics In Porcine Skin: Emerging Technologies For The Imaging Specialist, L. Thomas Johnson, Thomas W. Radmer, Dean C. Jeutter, Gary L. Stafford, Joseph Thulin, Thomas Wirtz, George Corliss, Kwang Woo Ahn, Alexis Visotky, Ronald L. Groffy Jan 2014

Replication Of Known Dental Characteristics In Porcine Skin: Emerging Technologies For The Imaging Specialist, L. Thomas Johnson, Thomas W. Radmer, Dean C. Jeutter, Gary L. Stafford, Joseph Thulin, Thomas Wirtz, George Corliss, Kwang Woo Ahn, Alexis Visotky, Ronald L. Groffy

School of Dentistry Faculty Research and Publications

This study demonstrates that it is sometimes possible to replicate patterns of human teeth in pig skin and determine scientifically that a given injury pattern (bite mark) correlates with the dentitions of a very small proportion of a population dataset, e.g., 5 percent or even 1 percent. The authors recommend building on the template of this research with a sufficiently large database of samples that reflects the diverse world population. They also envision the development of a sophisticated imaging software application that enables forensic examiners to insert parameters for measurement, as well as additional methods of applying force to produce …


Parent Attributional Style And Early Termination From Child And Parent Therapy, Ryan James Mattek Sep 2013

Parent Attributional Style And Early Termination From Child And Parent Therapy, Ryan James Mattek

Dissertations (1934 -)

ABSTRACT

PARENT ATTRIBUTIONAL STYLE AND EARLY TERMINATION

FROM CHILD AND PARENT THERAPY

Ryan J. Mattek, M.A.

Marquette University, 2013

Behavior problems are prevalent in young children and represent a threat to a child's typical development. These early behavior problems are even more common in children from low-income, urban settings. If left untreated, such challenging behaviors may become ingrained and lead to later more severe behaviors including aggression, violence, and anti-social behaviors. Research has demonstrated that participation in child and parent therapy (CPT) programs significantly reduces problematic child behaviors while increasing positive behaviors in both the child and the parent. However, …


Supervisees' Experiences Of Ruptures In Multicultural Supervision: A Qualitative Study, Laura Lubbers Sep 2013

Supervisees' Experiences Of Ruptures In Multicultural Supervision: A Qualitative Study, Laura Lubbers

Dissertations (1934 -)

As the paradigmatic shift of multiculturalism emerges in counseling, the constructs of culture and context warrant examination in the supervision process. With an understanding that conflict is inevitable in supervision relationships particularly when cultural topics are being discussed, investigation into the process of ruptures and rupture repair as they take place within multicultural supervision is warranted. Despite the attention paid to addressing culture in supervision, surprisingly little empirical attention has focused on supervisee experiences of ruptures in multicultural supervision. This study sought to provide a deeper understanding of supervisees' experiences of ruptures in multicultural supervision. Twelve participants were interviewed regarding …

Muscle Fatigue And Motor Output Variability With Acute Stress In Healthy Young Adults And Veterans With Posttraumatic Stress Disorder, Manda Linea Keller Oct 2011

Muscle Fatigue And Motor Output Variability With Acute Stress In Healthy Young Adults And Veterans With Posttraumatic Stress Disorder, Manda Linea Keller

Dissertations (1934 -)

Acute stress can alter motor performance differently for men and women. The first aim of this dissertation addresses possible causes for the sex difference in the motor response of a low-intensity fatiguing contraction of the elbow flexor muscles to an acute stressor (difficult mental math) in young, healthy adults. Muscle fatigue increased for men and women when exposed to the stressor, but impairment was more prominent for the women. This work showed that fatigue in the central nervous system, specifically in cortical motor and premotor areas, as well as relaxation rates of the muscle (quantified with cortical stimulation) were not …
