An Investigation Of Motivational Dysfunctions In A Rat Model Of Effort-Related Choice Behavior: Behavioral And Neurochemical Evidence For Possible Novel Pharmacological Treatments, Renee A. Rotolo
Doctoral Dissertations
Motivational symptoms such as fatigue, anergia, and amotivation are seen in depression, Parkinson’s disease, schizophrenia, and other disorders. These symptoms are often left untreated by the most frequently prescribed antidepressants, which typically block serotonin transport. Considerable evidence implicates brain dopamine (DA) in the regulation of behavioral activation and effort-related aspects of motivation. Animal studies of effort-based choice are being used to provide formal models of motivational dysfunctions in humans. Drugs that block DA transport (DAT) are able to reverse the effort-related effects of the vesicular monoamine transport inhibitor tetrabenazine, a drug that blocks DA storage and depletes DA. Many of …

Friendship Dissolution In Adolescence: Considering The Factors Surrounding Dissolution And Their Associations With Adjustment, Kaitlin M. Flannery
Friendship Dissolution In Adolescence: Considering The Factors Surrounding Dissolution And Their Associations With Adjustment, Kaitlin M. Flannery
Doctoral Dissertations
Friendships are important relationships in the lives of adolescents. However, about half of adolescent best friendships end across the course of a school year, and very little research has focused on the factors surrounding their dissolution. The current study aimed to examine different aspects of friendship dissolution in adolescence, such as the number of friendship dissolutions experienced, the reasons driving dissolution, and the way that friendships ended in a sample of middle school students (N = 354). Results suggest that dissolutions are incredibly common, reported by 86% of the sample, that conflict/betrayal is the most common reason for friendship …
Exploring Mediators Of Religiosity And Depressive Symptoms In Married Couples, Andrew Rose
Exploring Mediators Of Religiosity And Depressive Symptoms In Married Couples, Andrew Rose
Doctoral Dissertations
Substantial research has established that increases in religiosity can serve as a protective factor against depression. However, almost no research has focused on this relationship within a couple relational framework. Theory and previous research provide evidence that there may be several indirect or mediational pathways whereby this relationship is manifest. Three longitudinal Actor-Partner Interdependence Models were used to test the relationships between religiosity at Time 1, forgiveness at Time 3, marital satisfaction at Time 4 and depressive symptoms at Time 5. Data came from a longitudinal sample of 315 married couples who were studied over a five year period. Religiosity …
“Un Pueblo Tan Dulce”: Diabetes, Depression, And Obesity Syndemics In Puerto Rico, Shir Lerman
“Un Pueblo Tan Dulce”: Diabetes, Depression, And Obesity Syndemics In Puerto Rico, Shir Lerman
Doctoral Dissertations
Diabetes, depression, and obesity are global health crises that disproportionately affect people with low socioeconomic status and other marginalized identities. These diseases have high incidence and prevalence rates in Puerto Rico due to high poverty and unemployment rates, changing dietary patterns, and Puerto Rico’s political status as a U.S. commonwealth. The myriad problems on the island contribute to the flight of Puerto Ricans to the mainland in search of better education and employment; there are currently more Puerto Ricans living on the mainland than there are in Puerto Rico. Puerto Rico’s political status is of particular importance, as it simultaneously …
Jane Minot Sedgwick Ii And The World Of American Catholic Converts, 1820-1890, Erin M. Bartram
Jane Minot Sedgwick Ii And The World Of American Catholic Converts, 1820-1890, Erin M. Bartram
Doctoral Dissertations
When Jane Minot Sedgwick II (1821-1889), the daughter of an elite New England Unitarian family, became a Catholic in 1853, she joined a new faith culture while remaining embedded in the social world of her birth. As a young woman, she was uninterested in her family’s religious activities and uncomfortable with their zeal. This dissertation argues that Sedgwick only came to see Catholicism as a viable religious option after developing friendships with other elite women who had recently converted. After studying Catholicism for ten years, Sedgwick joined the Church, a decision she described as rational. In light of her independent …
Empirical Examination Of Caregiver Empowerment, Appraisal, And Depressive Symptoms Among Adult Siblings Of Individuals With Intellectual And Developmental Disabilities, Mamta Saxena
Doctoral Dissertations
Today, 72% of individuals with intellectual and developmental disabilities (IDDs) in the United States live with a caregiver (Braddock & Rizzolo, 2013). In many families, siblings of individuals with IDDs are the default long-term care providers (Heller et al., 2008). Despite the fact that research has begun to recognize and explore the roles of family members in care, little is known about sibling support providers (SSPs). Exploration and confirmation of the caregiving processes and outcomes of siblings can have implications for policy, research, and practice. The purpose of this study was to examine a conceptual model of caregiving processes and …
