Racial Identity, Hair Esteem, Hair Texture, And Hairstyle Choice As Correlates Of Psychological Well-Being Among Afro-Latinas In The United States, Marielsy Esther Pimentel

Dissertations

Problem

During the Colonial period, hair was one of the designated phenotypic markers of racial group membership used to assign or deny privilege. Privileges are still assigned to people based on their racial group membership and their proximity to Whiteness. As such, Hair remains a salient part of Afro-Latina women’s lives and identities, with its influences seen in the personal, social, and mental realms. How an Afro-Latina wears her hair can have legal, social, and intrapersonal consequences. The subsequent treatment of Afro-Latinas because of their hairstyle can affect how they view themselves and even how they relate to others, especially …

Indicators Of Typology In The Narrative Of Elijah: An Investigation Into The Predictive Nature Of Biblical Theology, JôNatas De Mattos Leal

Dissertations

Elijah is among the most popular prophets in the Judeo-Christian tradition. In Judaism, the hope for his return has evolved into a plethora of legends in which he functions as a helper to the righteous in the present and avenger to the wicked in the future eschaton. In Christianity, the expectation involving his return has also a multitemporal dimension, but its fulfilment is typologically oriented. More often, scholars study the fulfilment of the Elijah typology from the NT perspective in a backward movement. This dissertation investigates this typology in a forward movement going from the OT to the NT while …

Phosphorus Use And Management Based On Fertilizer Placement, Rate Of Application, And Soil Biota In No-Till Situations, Brennan Alexander Bingham Lewis

Electronic Theses and Dissertations

Phosphorus (P) pollution has become a concern among multiple scientific organizations as it leads to eutrophication, an algal bloom that depletes lacustrine and marine ecosystems of native species. Multiple strategies can be implemented to reduce phosphorus loss from agriculture fields, which is often implicated as a cause of eutrophication. Soil phosphorus chemistry results in phosphate fertilizers absorbing to clay minerals over time. Soil phosphorus is lost from agricultural fields primarily through wind and water erosion. No-till practices prevent soil erosion, which reduces the phosphorus from loading into waterways. Fertilizer placement affects phosphorus loss. Surface application of phosphorus fertilizers increases the …
