A Theory-Guided Investigation Of Proposed Factors That Influence The Relationship Between Cybervictimization And Psychological Adjustment In Late Adolescents, Melissa K. Hord Dec 2015

A Theory-Guided Investigation Of Proposed Factors That Influence The Relationship Between Cybervictimization And Psychological Adjustment In Late Adolescents, Melissa K. Hord

Electronic Theses and Dissertations

Cybervictimization is related to negative psychological adjustment (e.g., Tokunaga, 2010); however, not all cybervictims report negative outcomes, and it is not clear what factors may influence vulnerability. One possibility is that cybervictims’ attributions regarding technology-based communication impact their emotional adjustment. Those who make hostile intent attributions in ambiguous situations are more likely to experience negative outcomes (e.g., Crick & Dodge, 1994), and the inherent ambiguity of electronic communication may be particularly susceptible to misinterpretation. In addition, how individuals respond to cyber experiences may serve to either protect or damage their emotional well-being. Furthermore, those who are high in rejection sensitivity …


The Temporal Nature Of The Acute Stress Response And Its Impact On Explicit Learning, Steven B. Hutchinson Dec 2015

The Temporal Nature Of The Acute Stress Response And Its Impact On Explicit Learning, Steven B. Hutchinson

Dignity is “an internal state of peace that comes with the recognition and acceptance of the value and vulnerability of all living things” (Hicks, 2011, p. 1). Dignity is a crucial element in effective governance arrangements. This study applies dignity theory, and related theories of natural resource governance and environmental communication, to understand and overcome barriers to effective governance of common pool resources in rural communities. Chapter 1 reviews relevant literature on natural resource governance and develops a theoretical framework for dignity. Chapter 2 applies dignity theory to a contentious comprehensive planning process in a small Maine town in order …


Nurses’ Perceptions Of Self As Role Models Of Health, Shelia Hurley Dec 2015

Nurses’ Perceptions Of Self As Role Models Of Health, Shelia Hurley

Electronic Theses and Dissertations

Given the sad state of obesity and lifestyle-related illnesses in the US, nurses, as the largest and most trusted health profession, must take the cause of health promotion seriously and personally. This study seeks to close the gap in knowledge of nurses’ perception of self as a role model of health and personal healthy lifestyle behaviors. This study focuses on four specific behaviors that lead to a healthy lifestyle: limit alcohol, avoid tobacco, improve nutrition, and engage in physical activity. The purpose of this study is to determine the relationship between nurses’ health practices and their perceptions of self as …


Suicide Prevention Strategies In Tennessee Community Colleges: A Case Study, Sandra Perley Dec 2015

Suicide Prevention Strategies In Tennessee Community Colleges: A Case Study, Sandra Perley

Electronic Theses and Dissertations

Suicide is the second leading cause of death for college students; annually approximately 1,100 students in institutions of higher education die by suicide. However, most research related to college student suicide was conducted using the sample of 4-year institutions. Community colleges have seldom been included in the sample of suicide research studies. This qualitative case study research explored the student suicide prevention strategies in the 13 community colleges in the Tennessee Board of Regents higher education system. Data were collected from surveys, institutional web sites, and interviews with institutional personnel.

Approximately half of the institutions offer suicide prevention information to …


Shifts In Ritual Response To Loss Due To Death: An Assessment Of Funeral Service Mourning Trends Over Time, Lawrence D. Childress Dec 2015

Shifts In Ritual Response To Loss Due To Death: An Assessment Of Funeral Service Mourning Trends Over Time, Lawrence D. Childress

Electronic Theses and Dissertations

Bereavement, while universal, is experienced and expressed uniquely; it is both ultimate and particular. As the predominant social expression of grief, funerals are purported to be waning and/or transitioning to emergent, less conventional ceremonial forms. In this research, the possible salutary utility of funerals is outlined, and trends relative to the cost, nature (type), and prevalence of funeral services are examined relative to an extant data set from two funeral homes of shared ownership in northeast Tennessee. This data analysis of specific funeral trends in south central Appalachia is juxtaposed against the broader backdrop of current theoretical, clinical, and socio-cultural …


A Phenomenological Study Of Anticipated Intimacy And Sexual Expression Needs Of Aging Male And Female Baby Boomers., Charles Shawn Oak Dec 2015

A Phenomenological Study Of Anticipated Intimacy And Sexual Expression Needs Of Aging Male And Female Baby Boomers., Charles Shawn Oak

Electronic Theses and Dissertations

The purpose of this study was to understand the phenomenon of how heterosexual Baby Boomers define and understand intimacy, sexual expression, along expectations and desires relating to their respective expressions across the lifespan through their individual experiences and reflections. A set of guiding questions were used in a hermeneutic phenomenological qualitative research design. Data was gathered from thirteen subjects (n=13) using the Rappaport Time Line (RTL) that was used to develop individualized semi-structured interviews and follow-up interviews that were professionally transcribed. These were coded to identify emergent themes. Results of the study provided insight into the phenomenon of how heterosexual …


A Culturally-Sensitive Model Of The Development Of Child Anxiety., Jenny Marie Petrie Dec 2015

A Culturally-Sensitive Model Of The Development Of Child Anxiety., Jenny Marie Petrie

Electronic Theses and Dissertations

Explanatory models significantly enhance the understanding of etiological influences that place children at risk for anxiety, yet little is known about processes that promote resilient outcomes in children. While contextual factors influence risk and protective processes, cultural constructs have not been incorporated into existing models of anxiety and the role of culture remains obscure. The current study proposes a culturally sensitive model for understanding the etiological and mitigating processes underlying anxious symptoms in ethnic minority youth, and preliminarily tests basic components of the proposed model within a non-clinical community sample of 49 African American (AA) parent-child dyads who completed self-report …


Self-Compassion And Self-Forgiveness As Mediated By Rumination, Shame-Proneness, And Experiential Avoidance: Implications For Mental And Physical Health, Elizabeth Conway Williams Aug 2015

Self-Compassion And Self-Forgiveness As Mediated By Rumination, Shame-Proneness, And Experiential Avoidance: Implications For Mental And Physical Health, Elizabeth Conway Williams

Electronic Theses and Dissertations

Self-compassion and self-forgiveness appear to have much in common, as both relate to one’s self-regard during challenging circumstances; however, their empirical relationship is largely yet to be explored. The present study examines theoretical and empirical areas of overlap and proposes a theory of their relationship, including its possible impact on health. Self-compassion and self-forgiveness were proposed to have a direct relationship that may be mediated by reduction in rumination, shame, and experiential avoidance. These factors together were also hypothesized to have a positive impact on health functioning. The current study tested these models in a sample of undergraduate students (n …


Risk And Protective Factors Of Internalized Mental Illness Stigma, Kathleen Klik Aug 2015

Risk And Protective Factors Of Internalized Mental Illness Stigma, Kathleen Klik

Electronic Theses and Dissertations

The internalization of mental illness stigma is associated with an array of negative consequences; however, not all individuals experience the deleterious effects of internalized mental illness stigma. The present dissertation focuses on factors associated with internalized stigma, and will be the first to examine simultaneously both risk (i.e., shame, shame proneness and shame aversion, insight, and centrality and valence) and protective factors (social support and self-compassion) of internalized mental illness stigma. Using two of the most widely used assessments of internalized mental illness stigma (i.e., Self-Stigma of Mental Illness Scale [SSMIS] and the Internalized Mental Illness Scale [ISMI]), risk and …


Testing The Chronic Care Model For Depression In Homebound Older Adults., Brittney Rose Getz Aug 2015

Testing The Chronic Care Model For Depression In Homebound Older Adults., Brittney Rose Getz

Electronic Theses and Dissertations

Homebound older adults are a unique population of older adults with many chronic illnesses and complex care needs (Qui et al., 2010). Depression is highly prevalent in homebound older adults (Qui et al., 2010). Many Chronic Care Models (CCMs) have been developed to provide a better system of care to those with chronic health conditions (Bodenheimer, Wagner, & Grumbach, 2002; Wagner et al., 2001; Wagner, Austin, & Von Korff, 1996a, 1996b). The Chronic Care Model for Depressed Homebound Older Adults is a model that was specifically designed for the depressed homebound elderly. It addresses many areas for improvement of care …


Temporal Information Processing Across Primary Visual Cortical Layers In Normal And Red Light Reared Tree Shrews., Wenhao Dang Aug 2015

Temporal Information Processing Across Primary Visual Cortical Layers In Normal And Red Light Reared Tree Shrews., Wenhao Dang

Electronic Theses and Dissertations

Visual neuroscience research has benefitted from decades of efforts of comparative studies of different species, since exploring and understanding the diversity of functional properties of visual system in different species has helped us identify both general organization rules and unique traits of certain species. In this study, spatio-temporal receptive fields (STRFs), together with some other functional properties (etc. stimulus preference to different visual stimuli, orientation tuning, temporal frequency tuning and the F1/F0 ratio of responses to sine-wave grating stimuli), of primary visual cortex (V1) cells were measured in normally reared and red-light reared tree shrews (Tupaia), a species considered the …


An Analysis Of The Interaction Of Methylphenidate And Nicotine In Adolescent Rats: Effects On Bdnf, Elizabeth D. Freeman Aug 2015

An Analysis Of The Interaction Of Methylphenidate And Nicotine In Adolescent Rats: Effects On Bdnf, Elizabeth D. Freeman

Electronic Theses and Dissertations

This investigation was an analysis of the interaction of adolescent exposure to methylphenidate (MPH; trade name: Ritalin) on nicotine sensitization and conditioned place preference (CPP) in a rodent model and underlying mechanisms of this effect. Animals were treated IP with 1 mg/kg MPH or saline using a ―school day‖ regimen of five days on, two days off, from postnatal day (P) 28-50. During the final two weeks of MPH treatment, animals were either behaviorally sensitized to nicotine (0.5 mg/kg free base) or saline for 10 days, or conditioned to nicotine or saline using the CPP behavioral paradigm. In addition, three …


The Neuropsychological Profile Of Older Adult Musicians And Non-Musicians : Implications For Cognitive Reserve In Late Life., Jessica Vemich Strong, Aug 2015

The Neuropsychological Profile Of Older Adult Musicians And Non-Musicians : Implications For Cognitive Reserve In Late Life., Jessica Vemich Strong,

Electronic Theses and Dissertations

Published literature studying children and adults musicians suggests significant differences in neuroanatomy, in brain regions that include the auditory and motor cortices, language centers, and frontal regions and tracts. Studies examining cognitive correlates to these neuroanatomical differences have consistently found that children and adult musicians have better cognitive abilities in the domains of language, verbal or non-verbal memory and executive function. Only one study has examined the differences in cognitive performance between older adult musicians and non-musicians to see how normal age-related cognitive changes may affect these differences. The current study compared cognitive test performance among older adult non-musicians, low-activity …


Effects Of Amplitude Modulation On Sound Localization In Reverberant Environments., Paul W. Anderson Aug 2015

Effects Of Amplitude Modulation On Sound Localization In Reverberant Environments., Paul W. Anderson

Electronic Theses and Dissertations

Auditory localization involves different cues depending on the spatial domain. Azimuth localization cues include interaural time differences (ITDs), interaural level differences (ILDs) and pinnae cues. Auditory distance perception (ADP) cues include intensity, spectral cues, binaural cues, and the direct-to-reverberant energy ratio (D/R). While D/R has been established as a primary ADP cue, it is unlikely that it is directly encoded in the auditory system because it can be difficult to extract from ongoing signals. It is also noteworthy that no neuronal population has been identified that specifically codes D/R. It has therefore been proposed that D/R is indirectly encoded in …


What We See Changes How We See : Analyzing The Plasticity Of The Horizontal Effect., April Marie Schweinhart Aug 2015

What We See Changes How We See : Analyzing The Plasticity Of The Horizontal Effect., April Marie Schweinhart

Electronic Theses and Dissertations

The relationship between the processing of orientations by the human visual system has been related to the orientation content of the natural environment; horizontal orientations, while predominant in natural environments, are perceived less well than vertical and oblique orientations are perceived best, though they are least prevalent in the natural world. This ‘horizontal effect’ has further extended the well-studied relationship between visual encoding and natural scene statistics as the differential perception of orientations in broadband scenes inversely matches their differential representation in the natural environment. However, the original hypothesis that this relationship may have evolved across millennia in order to …


Awareness Of Executive Functioning As A Diagnostic Tool For Mild Cognitive Impairment And Alzheimer's Disease., Jeremy Stark Carmasin Aug 2015

Awareness Of Executive Functioning As A Diagnostic Tool For Mild Cognitive Impairment And Alzheimer's Disease., Jeremy Stark Carmasin

Electronic Theses and Dissertations

This study examined the utility of older adults’ awareness of their executive functioning abilities to predict future cognitive decline. The recently revised Cognitive Awareness Model (CAM) forms the conceptual background of this approach, and suggests that executive dysfunction disrupts awareness in a manner distinct from episodic memory dysfunction. The study design examined how awareness of executive functioning ability may predict both continuous decline on neuropsychological testing and qualitative change in diagnostic status. This form of prediction was tested using a longitudinal sample (n = 661) of older adults with either normal cognition, mild cognitive impairment (MCI), or Alzheimer’s disease (AD). …


Anger Rumination, Stress, And Dangerous Driving Behaviors As Mediators Of The Relationship Between Multiple Dimensions Of Forgiveness And Adverse Driving Outcomes, David J. Bumgarner Aug 2015

Anger Rumination, Stress, And Dangerous Driving Behaviors As Mediators Of The Relationship Between Multiple Dimensions Of Forgiveness And Adverse Driving Outcomes, David J. Bumgarner

Electronic Theses and Dissertations

Motor-Vehicle crashes are the leading cause of death for teens and young adults. Research and public interventions have primarily examined the impact of external factors related to driving; however, less work has examined internal factors. Limited research has shown a negative association between trait forgiveness of others and both driving anger and driving aggression. The current study replicates previous findings and expands to include multiple dimensions of forgiveness and adverse driving outcomes as a dependent variable. It was predicted that multiple dimensions of forgiveness would be directly and indirectly related to adverse driving outcomes through the mediators of anger rumination, …


Identity As A Buffer Against Negative Outcomes Of Public Stigma Among Lesbian, Gay, And Bisexual Individuals, Emma G. Fredrick May 2015

Identity As A Buffer Against Negative Outcomes Of Public Stigma Among Lesbian, Gay, And Bisexual Individuals, Emma G. Fredrick

Electronic Theses and Dissertations

Sexual minority individuals suffer stigmatization which often predicts negative mental health outcomes and low self-esteem. However, specific dimensions of identity have been shown to buffer against negative outcomes in racial minorities and other stigmatized groups. Yet, limited research has examined identity as a buffer for sexual minorities. This thesis aimed to explore the moderating role of identity characteristics between sexual stigma and mental health outcomes. Findings in a sample of 209 gays, lesbians, and bisexuals suggested that public stigma, centrality, and private regard predict psychological distress. Private regard also emerged as a predictor of self-esteem. Additionally, centrality and public stigma …

Exploring The Relationship Between Early Childhood Attentional Control And Language Ability, Jaima S. Price May 2015

Exploring The Relationship Between Early Childhood Attentional Control And Language Ability, Jaima S. Price

Electronic Theses and Dissertations

Relatively few studies have investigated the relationship between early childhood attentional control and later cognitive outcomes, especially language development. The current study is an investigation of the relationship between the executive functioning (EF) component of attentional control and language ability in the second year of life. More specifically, the predictive nature of two aspects of attentional control, attentional focus and resistance to distraction, was be the primary focus of the proposed study. Although it was expected that children both high in attentional focus and resistance to distraction would have significantly superior language development than infants with lower attentional capacities, analyses …


Intimate Partner Psychological Abuse And Posttraumatic Stress Symptoms : The Role Of Shame During Recall Of Psychological Abuse Memories., Kimberly N. Fleming May 2015

Intimate Partner Psychological Abuse And Posttraumatic Stress Symptoms : The Role Of Shame During Recall Of Psychological Abuse Memories., Kimberly N. Fleming

Electronic Theses and Dissertations

To help understand why intimate partner psychological abuse has been associated with posttraumatic stress (PTS) symptoms in past studies, two studies of college-aged individuals tested a mediational model in which shame during recall was hypothesized to mediate associations between psychological abuse memory recall and PTS symptom severity. The model was partially supported. Experiment 1 established the first piece of the model by linking recall of a psychological abuse memory to increases in state shame from pre- to post-recall. Consistent with the hypothesis, there was a statistically significant interaction between memory condition (psychological abuse memory, non-abuse relationship memory) and time of …


Differential Parenting And Parents' Perceptions Of Their Children: Can Attachment Help Explain This Relationship?, Meagan Mcswiggan Jan 2015

Differential Parenting And Parents' Perceptions Of Their Children: Can Attachment Help Explain This Relationship?, Meagan Mcswiggan

Electronic Theses and Dissertations

Research has suggested that the differential experiences of children in the same family were often greater than those of children across different families. Although studies identified potential moderators (e.g., age, gender) associated with differential parenting, there has been less investigation of mediators. The current study examined attachment as a mediator in the relationship between differential parenting and parents' perceptions of their children. As part of this study, 132 culturally diverse mothers with children who ranged in age from 2- to 10-years rated how differently they treat their own children, their children's attachment, their parenting characteristics, and their children's functioning (i.e., …


Temperament, Emotion Regulation, And Distress Tolerance As Related Correlates Of Psychological Symptoms, Catherine Pearte Jan 2015

Temperament, Emotion Regulation, And Distress Tolerance As Related Correlates Of Psychological Symptoms, Catherine Pearte

Electronic Theses and Dissertations

Researchers have postulated that those with difficult temperament are at risk for difficulties with regulating emotions, are less tolerant of distressing stimuli, have characteristic difficulty coping with distress, and are (at some periods of development) more apt to experience clinically significant psychological symptoms. This study used exploratory factor analyses and structural equation modeling to compose and test a model that explained how emotion regulation, distress tolerance, and coping skills interact to explain how certain temperament features translate into psychological symptoms. Because those with difficult temperament were thought to be at a unique risk for psychological maladjustment, mean-based criterion were used …


The Subjective Gameplay Experience: An Examination Of The Revised Game Engagement Model, Katelyn Procci Jan 2015

The Subjective Gameplay Experience: An Examination Of The Revised Game Engagement Model, Katelyn Procci

Electronic Theses and Dissertations

The study of the subjective gameplay experience spans multiple disciplines, from teachers who want to harness the power of gameplay to enhance instruction to game developers hoping to create the next big hit. Despite decades of interest, little agreement has been found regarding the way constructs—such as immersion, involvement, presence, and flow—are used to describe the subjective gameplay experience. Without the consistent usage of well-defined constructs, it becomes impossible to further scientific understanding of this domain. This dissertation examined the theoretical evolution of the key subjective gameplay experience constructs. From this, definitions for immersion, involvement, presence, and flow were extracted. …


Psychometric Issues Related To The Tinker Toy Test, Daniel Guzman Jan 2015

Psychometric Issues Related To The Tinker Toy Test, Daniel Guzman

Electronic Theses and Dissertations

An evaluation of executive functioning is a critical component of a comprehensive assessment of higher cerebral functioning. The Tinker Toy Test (TTT) was introduced in 1982. This test allows an individual to demonstrate the extent of their executive capacities by permitting them to initiate, plan, and structure a potentially complex activity and carry it out independently in an unstructured fashion and administration is simple. This is a departure from more complex and structured tests of executive function. There is a dearth of research on the TTT and this study seeks to examine some of the psychometric properties of this instrument; …


Assessment Center Structure And Construct Validity: A New Hope, Christopher Wiese Jan 2015

Assessment Center Structure And Construct Validity: A New Hope, Christopher Wiese

Electronic Theses and Dissertations

Assessment Centers (ACs) are a fantastic method to measure behavioral indicators of job performance in multiple diverse scenarios. Based upon a thorough job analysis, ACs have traditionally demonstrated very strong content and criterion-related validity. However, researchers have been puzzled for over three decades with the lack of evidence concerning construct validity. ACs are designed to measure critical job dimensions throughout multiple situational exercises. However, research has consistently revealed that different behavioral ratings within these scenarios are more strongly related to one another (exercise effects) than the same dimension rating across scenarios (dimension effects). That is, results from ACs suggest that …


Team Interaction Dynamics During Collaborative Problem Solving, Travis Wiltshire Jan 2015

Team Interaction Dynamics During Collaborative Problem Solving, Travis Wiltshire

Electronic Theses and Dissertations

This dissertation contributes an enhanced understanding of team cognition, in general, and collaborative problem solving (CPS), specifically, through an integration of methods that measure team interaction dynamics and knowledge building as it occurs during a complex CPS task. The need for better understanding CPS has risen in prominence as many organizations have increasingly worked to address complex problems requiring the combination of diverse sets of individual expertise to achieve solutions for novel problems. Towards this end, the present research drew from theoretical and empirical work on Macrocognition in Teams that describes the knowledge coordination arising from team communications during CPS. …


Friendship And Informant Characteristics Associated With Agreement Among Adolescent And Friend Ratings Of Behavior Problems., Brea-Anne Lauer Jan 2015

Friendship And Informant Characteristics Associated With Agreement Among Adolescent And Friend Ratings Of Behavior Problems., Brea-Anne Lauer

Electronic Theses and Dissertations

Although teacher and parent informants often are used to gather information regarding adolescents* emotional and behavioral functioning, research has suggested that agreement among these raters and adolescents* self-ratings tends to be low to moderate. Given that friends typically play an important role in the lives of adolescents, the present study sought to determine the relative agreement amongst adolescent self-reports and those of their friends as well as factors that might impact this agreement. In particular, a sample of 207 culturally diverse high school students were matched based on perceived friendship closeness and asked to provide ratings of their own emotional …
