Academic Incivility: Can The Dark Triad Personality Traits Predict Academic Entitlement?, Melissa M. Foley

Walden Dissertations and Doctoral Studies

Academic entitlement is a view held by students that can cause dissent and student incivility. Academic entitlement can be driven by various factors, including the personality traits of the Dark Triad (personality traits of Machiavellianism, psychopathy, and narcissism). Other researchers have examined the relationship between these traits and academic entitlement, but further research on this subject is needed. Adams’ equity theory, which proposes that people experience distress when they identify as either under- or over rewarded individuals, provided the theoretical foundation for this study. Using a quantitative approach, 160 participants were recruited using online methods and asked to complete a …

Forensic Insight On Predatory Behavior: Fantasy And Relational Paraphilic Attachments In Stalker Processing, Elizabeth Ann Duemig

Walden Dissertations and Doctoral Studies

Despite the push to criminalize stalking, many of the actions that would legally fall under these provisions do not materialize into stalking-based arrests or convictions as stalking frequently becomes a lesser included offense under charges that escalate into violence. Insight into offender pathways related to predatory pursuit could serve to inform individuals faced with the forensic challenges of legal decision-making. The dynamics of stalking behavior include elements of fantasy and attachment. The objective of this study was to examine patterns of violent sexual fantasies and relational paraphilic attachment (RPA) in an offender’s process of stalking preselected victims. The research question …

How Feminist Beliefs Relate To Self-Objectification In African American Females, Ashton Shelby

Walden Dissertations and Doctoral Studies

Sexual objectification has consistently been found to significantly influence self-objectification in women. Self-objectification has been linked to a number of adverse effects in women including depression, sexual dysfunction, and disordered eating. All females are vulnerable to sexually objectifying experiences and thus, developing self-objectifying behaviors and issues. Although extensive research explores both forms of objectification with Caucasian females, less is known about females in minority groups. In addition, little research has explored potential moderating variables. In other research related to investigating women’s mental health, feminism is one variable that has been found to have a positive effect on women’s issues. This …
