Urban Dwellers Experiences Regarding Loss Of Natural Environments Due To Rapid Urbanization, Erica Montanye

Walden Dissertations and Doctoral Studies

Little is known about how residents of rapidly growing cities are impacted by the loss of natural environments. Large cities are expanding at an exponential rate, reducing the presence of, and access to, natural environments for urban dwellers. Many benefits to human health regarding the presence of natural environments near where people live and work are known, but impacts of the loss of natural environments for urban dwellers are unknown. The purpose of this qualitative investigation was to understand residents' experiences regarding the loss of natural environments and related impacts. Attention restoration theory and place attachment were the theoretical lenses …

An Exploration Of Emotional Intelligence In Victim-Survivors Of Intimate Partner Violence, Terri L. Ratliff

Walden Dissertations and Doctoral Studies

Despite decades of preventive education and services for intimate partner violence, such violence continues. Studies have shown mixed evidence regarding the effectiveness of current treatment options and prevention remains paramount. If victims seek therapy, the focus is typically on a single diagnosis, such as depression or post-traumatic stress disorder, rather than cause-and-effect. Emotional intelligence in abusers of intimate partner violence has been tested and studied. There is literature on victims, but they are rare, regional, and examined only female participants resulting in conflicting findings. There is a gap in research in the review of the nuances of emotional intelligence in …

Barriers To Mental Health Treatment Among Chronically Homeless Women: A Phenomenological Inquiry, Rebecca Keeler Spicer

Walden Dissertations and Doctoral Studies

Homeless women demonstrate higher rates of mental illness than homeless men. The combination of complex life circumstances, stigmas related to mental illness, and homelessness may cause homeless women with mental illnesses to face unique barriers that prevent them from accessing necessary mental health services. The purpose of this phenomenological study was to expand the body of literature on homeless women's experiences with the mental health system and to understand the barriers to treatment services. Guided by Young's critical social theory of gender, this study was designed to develop a better understanding of the support that may be in place to …

Intimate Partner Violence In Military Couples, Kristy Wood

Walden Dissertations and Doctoral Studies

Intimate partner violence is negatively impacting the military community. This social issue is not understood well enough to create effective prevention programs or improve intervention programs. Missing from the literature is research investigating the complex nature of intimate partner violence using attachment as the framework. The purpose behind this quantitative, cross-sectional study was to understand the relationships between attachment styles, posttraumatic stress disorder, and intimate partner violence. Whether traumatic brain injury mediates these relationships was considered. There were 228 surveys collected from military couples, using the Adult Attachment Scale, Posttraumatic Stress Disorder Checklist-Military Version, and Intimate Justice Scale. Traumatic brain …

Terrorism And Parents' Experience Of Children's Schooling In Nigeria: A Phenomenological Study., James Ovu Urien

Walden Dissertations and Doctoral Studies

In Nigeria, displaced non-Muslim parents living in refugee camps face difficult decisions regarding the schooling of their teenage daughters, who are potential targets of Boko Haram terrorist activities. The purpose of this interpretative phenomenological analysis (IPA) was to qualitatively explore a deeper understanding of the lived experience of displaced non-Muslim parents in Nigeria concerning the schooling of their teenage daughters. Prospect theory provided a theoretical foundation for the study. The theory holds that decision-making is based on the perceived value of gains and losses under risk conditions, rather than solely the perceived final outcome of the risk. The research questions …

Relationships Between Sales Management Control, Salesperson Role, And Salesperson Performance, Michelle Vazzana

Walden Dissertations and Doctoral Studies

Organization theory proposes that managers exert control over the behavior of salespeople and the outcomes salespeople are expected to deliver. The purpose of this quantitative, nonexperimental study was to examine the relationships between activity control, capability control, and outcome control and salesperson performance, as well as the moderating effects of product complexity, task complexity, and number of accounts on the control-performance relationships for business-to-business sales personnel. The framework for the study was based in the concept of organizational control. Data analysis included hierarchical regression of a convenience sample of 374 survey responses from salespeople to analyze the direct and moderating …

Comparisons Of Artifact Correction Procedures For Meta-Analysis: An Empirical Examination On Correcting Reliabilities, Lei Zhao

Dissertations

This study reviewed some challenges and issues in artifact correction meta-analysis, particularly around using reliability estimates to correct for measurement error. Two individual correction procedures—the Hunter-Schmidt procedure and the procedure developed by Raju, Burke, Normand, and Langlois (the RBNL procedure)—are addressed in this research. The purpose of this study is to use real-world data to examine the differences between meta-analytic estimations produced by the two artifact correction procedures and those by the traditional bare-bones meta-analysis procedures, under the condition of inter-dependent reliabilities. The impact of this inter-correlation on meta-analysis results needs investigation when artifact indicators, such as reliability of predictor …

Improving Planning: Quantitative Evaluation Of The Premortem Technique In Field And Laboratory Settings, Madeline Peabody

Dissertations, Master's Theses and Master's Reports

This thesis compares different plan evaluation techniques in a series of experiments. The Premortem plan evaluation method can help people reduce overconfidence and generate more reasons a plan might not succeed. This research evaluates the extension of the Premortem to shorter planning time periods, evaluates the effectiveness with team generated and executed plans, and compares the use of this technique among individuals and teams. In Experiment 1, 52 Army Cadets operating in teams completed six time-constrained field exercises that required planning, half using the Premortem and half using a standard Military plan evaluation process. When teams used the Premortem they …

Finding The Ghost With The Machine: Breaking Through The Assessment Center Validity Ceiling By Exploring Decisional Processes Using New Sources Of Behavioral Data Within Virtual Assessments, Brett W. Guidry

Open Access Dissertations

Decades of assessment center (AC) research has resulted in an inevitable “validity ceiling” whereby increasing the validity of the AC method is becoming increasingly difficult. To overcome this challenge, new avenues for collecting and evaluating AC participant behaviors must be explored, with a particular focus on overcoming the inherent limitations of human observation—a hallmark of the AC method. This study examines detailed logs of AC participant behaviors captured automatically and unobtrusively during a computer-based simulation assessment. Using a decision making framework, basic characteristics of the new behavioral data are tested against existing theories of decisional efficacy. The construct-related validity of …

Multiple Imputation Of Missing Data In Structural Equation Models With Mediators And Moderators Using Gradient Boosted Machine Learning, Robert J. Milletich Ii

Psychology Theses & Dissertations

Mediation and moderated mediation models are two commonly used models for indirect effects analysis. In practice, missing data is a pervasive problem in structural equation modeling with psychological data. Multiple imputation (MI) is one method used to estimate model parameters in the presence of missing data, while accounting for uncertainty due to the missing data. Unfortunately, commonly used MI methods are not equipped to handle categorical variables or nonlinear variables such as interactions. In this study, we introduce a general MI framework that uses the Bayesian bootstrap (BB) method to generate posterior inferences for indirect effects and gradient boosted machine …

An Item Response Theory Analysis Of Emotional Expressivity Measures, Melissa K. Matheys

Theses and Dissertations

The understanding of psychometric properties of emotional expressivity measures is often limited to rudimentary statistics. The present study investigated, in depth, the psychometric properties of four measures of emotional expressivity (the Self-Concealment Scale, the Distress Disclosure Index, the Emotional Expressivity Scale, and the Emotion Regulation Questionnaire – Suppression subscale). Item response theory (IRT) analyses suggested that recoded versions of the measures’ Likert scales may be beneficial in practice as well as the deletion of some measures’ items. IRT analyses of the four measures of emotional expressivity provide more information than classical test theory statistics about how to implement these measures …

Optimizing Cross-Battery Assessment Procedures For Reading-Based Specific Learning Disorder Diagnosis: A Monte Carlo Study, Zachary Joseph Roman

Theses and Dissertations

Specific Learning Disorder is a disorder in which deficits in academic skills are caused by specific cognitive deficits. Cross-Battery Assessment (Flanagan, Alfonso, & Ortiz, 2013), is a popular method of diagnosing specific learning disorders. A recent study using data simulation methods claimed that cross-battery assessment was insufficiently accurate for clinical use (Stuebing, Fletcher, Branum-Martin, & Francis, 2012). However, the study used the general population base rate for specific learning disorders, resulting in misleadingly low accuracy estimates. The current study attempted to accurately simulate the cross-battery assessment method with a referred population prevalence to provide a fair analysis of cross-battery assessment’s …

The Psychometric Evaluation And Validation Of A Measure Assessing Pharmacological And Social Alcohol Expectancies In Adolescents, Megan Victoria Mcmurray

USF Tampa Graduate Theses and Dissertations

Extending prior alcohol expectancy measurement research, this researcher (McMurray, 2013) recently developed the Pharmacological and Social Alcohol Expectancy Scale (PSAES). The PSAES is the only alcohol expectancy measure to date that provides adequate coverage of both social expectancies and the anticipated positive pharmacological effects resulting from alcohol consumption, and was developed and validated in a sample of young adults (aged 18-23). Research has shown that adolescents at high risk for alcohol use disorder (AUD) hold higher expectations of reward from alcohol, suggesting that expectancy patterns may help distinguish at-risk youth. Building upon the previous PSAES validation study, the primary purpose …

Investigating Parameter Recovery And Item Information For Triplet Multidimensional Forced Choice Measure: An Application Of The Ggum-Rank Model, Philseok Lee

USF Tampa Graduate Theses and Dissertations

To control various response biases and rater errors in noncognitive assessment, multidimensional forced choice (MFC) measures have been proposed as an alternative to single-statement Likert-type scales. Historically, MFC measures have been criticized because conventional scoring methods can lead to ipsativity problems that render scores unsuitable for inter-individual comparisons. However, with the recent advent of classical test theory and item response theory scoring methods that yield normative information, MFC measures are surging in popularity and becoming important components of personnel and educational assessment systems. This dissertation presents developments concerning a GGUM-based MFC model henceforth referred to as the GGUM-RANK. Markov Chain …

Psychological Abuse, Mental Health, And Acceptance Of Dating Violence Among Adolescents, Jeff R. Temple, Hye Jeong Choi, Joanna Elmquist, Michael L. Hecht, Michelle Miller-Day, Gregory L. Stuart, Meagan Brem, Caitlin Wolford-Clevenger

Communication Faculty Articles and Research

Purpose

Existing literature indicates that acceptance of dating violence is a significant and robust risk factor for psychological dating abuse perpetration. Past work also indicates a significant relationship between psychological dating abuse perpetration and poor mental health. However, no known research has examined the relationship between acceptance of dating violence, perpetration of dating abuse, and mental health. In addition to exploring this complex relationship, the present study examines whether psychological abuse perpetration mediates the relationship between acceptance of dating violence and mental health (i.e., internalizing symptoms of depression, anxiety, and hostility).

Methods

Three waves of longitudinal data were obtained from …

Parametrically Constrained Lightness Model Incorporating Edge Classification And Increment-Decrement Neural Response Asymmetries, Michael E. Rudd

MODVIS Workshop

Lightness matching data from disk-annulus experiments has the form of a parabolic (2^nd-order polynomial) function when matches are plotted against annulus luminance on log-log axes. Rudd (2010) has proposed a computational cortical model to account for this fact and has subsequently (Rudd, 2013, 2014, 2015) extended the model to explain data from other lightness paradigms, including staircase-Gelb and luminance gradient illusions (Galmonte, Soranzo, Rudd, & Agostini, 2015). Here, I re-analyze parametric lightness matching data from disk-annulus experiments by Rudd and Zemach (2007) and Rudd (2010) for the purpose of further testing the model and to try to constrain …

A Learning Model For L/M Specificity In Ganglion Cells, Albert Ahumada

MODVIS Workshop

An unsupervised learning model for developing L/M specific wiring at the ganglion cell level would support the research indicating L/M specific wiring at the ganglion cell level (Reid and Shapley, 2002). Removing the contributions to the surround from cells of the same cone type improves the signal-to-noise ratio of the chromatic signals. The unsupervised learning model used is Hebbian associative learning, which strengthens the surround input connections according to the correlation of the output with the input. Since the surround units of the same cone type as the center are redundant with the center, their weights end up disappearing. This …

Examining Latent Change Classes: An Application Of Factor Mixture Modeling To Change Scores, Thai Q. Ong

Masters Theses, 2010-2019

Although change scores are used in a variety of statistical methods (e.g., analysis of variance and regression), there is a lack of application of latent variable modeling methods to change scores. This thesis provides a detailed description of two latent variable modeling methods applied to change scores: factor analysis of change scores and change score factor mixture modeling. To illustrate advantages of these methods, both were applied to change score data from undergraduates. Students responded to sense of identity items during a university-wide assessment day on two occasions, once as incoming freshmen and again as second-semester sophomores. Change scores were …

The Effect Of Anchoring Vignettes On Factor Structures: Student Effort As An Example, Carolyn A. Miesen

Masters Theses, 2010-2019

Anchoring vignettes are used as a methodological technique for removing differential interpretation of response categories (DIRC) from scores on subjective self-report measures (King, Murray, Slomon, & Tandon, 2004). This technique requires participants to read one or more short scenarios, or vignettes, designed to represent various levels of a construct. Vignette ratings are used as an indication of DIRC, which is a source of differential item functioning (DIF). Prior research primarily used indirect methods for evaluating vignette quality. In response, the present set of studies proposes using invariance testing as a more direct evaluation of how the use of anchoring vignettes …
