A Sense Of Entitlement To Self In Relationships: An Elaboration Of Attachment And Feminist Object Relations Theories, Suzanne Elaine Wolfe

Dissertations

Many women who present for psychotherapy with symptoms of depression and/or anxiety describe a common pattern of involvement in current and past nonmutual relationships. This phenomenon is described and explored in light of a new conception of entitlement. It is proposed that one’s sense of entitlement is a relative relational position along a continuum from overentitlement through healthy entitlement to underentitlement, and that these women are often underentitled in their adult relationships. Their relationships are often with overentitled others, and they may hold internal convictions that their place in relationships is to be underentitled. A particular pattern contributing to underentitlement …

Direct Service Staff's Perceptions Of Psychotropic Medication In Noninstitutional Settings For Individuals With Developmental Disabilities, Leeann Christian

Dissertations

Approximately 35-55% of individuals with mental retardation who live in the community are prescribed psychotropic and/or antiepileptic medication (Aman, Saphare, & Burrows, 1995; Singh, Guernsey, & Ellis, 1992). As more individuals with severe behavior challenges are transitioned from institutions into the community, these rates are likely to increase. Given these prevalence rates, it is important to determine whether staff who serve people with mental retardation are adequately educated about psychotropic medications. Previous studies (Aman, Singh, & White, 1987; Gadow, 1983; Singh, Epstein, Stout, Luebke, & Ellis, 1994; Singh et al., 1996) surveyed a variety of service providers in school and …

African-American Females And The Glass Ceiling In The Defense Logistics Agency, Velma Lee Clay

Dissertations

This study explores the career advancement experiences of African American women who have successfully broken through the glass ceiling.
