Memory Interference In The Lateral Entorhinal Cortex, Omar Ghazy

Dissertations, Theses, and Capstone Projects

Memory interference occurs when previously formed memories disrupt the acquisition or retrieval of new information. A prominent example of proactive interference is latent inhibition (LI), defined as a reduced ability to form or express Pavlovian associations with a stimulus following non-reinforced exposure. The interference-based model suggests that LI arises because the memory that the pre-exposed stimulus is inconsequential interferes with the memory that it predicts a reinforcer.

Because interference increases with age, identifying its neural basis may help prevent or slow cognitive decline. Prior studies using the LI paradigm implicate the entorhinal cortex (EC) in retrieving the memory that a …

Single Mother Poverty In A Global City, Gregory Cala

Dissertations, Theses, and Capstone Projects

The thesis explores how New York City's emergence as a "Global City" and welfare reform uniquely impacted single mothers’ lives on the matter of labor, housing, cost of living and more. New York City’s recovery from near bankruptcy in the 1970s began after cutting social programs and luring corporate firms with financial incentives. As firms moved to the city, so did their workforce of employees with skills in specialized service roles. Concurrently, the need for cheap, part-time, and temporary services emerged. By the 1990s, the growth of these less specialized service jobs outpaced all others, all while calls for work …

The Ethnobotany And Pharmacology Of Medicinal Plants For Caribbean Women’S Health, Ella Thomas Vardeman

Dissertations, Theses, and Capstone Projects

Approximately 55% of the world’s population lives in cities, and the United Nations estimates that this number will rise to 68% by 2050. Urban ethnobotany, the study of people’s traditional knowledge and use of plants in cities, is increasingly important as people adapt their cultural traditions to changing environments. In New York City (NYC), there have been several urban ethnobotany investigations in collaboration with Caribbean immigrant groups. However, there has yet to be an ethnobotanical survey that documents and botanically authenticates the medicinal plants used in the Haitian community. Previous collaborative research with women from the Caribbean in NYC has …

Parametrization Of Formal Norm Compatible Sequences, Joseph Dicapua

Dissertations, Theses, and Capstone Projects

We give a classification of power series parametrizing Lubin-Tate trace compatible sequences. This proof answers a question posed in the literature by Berger and Fourquaux. Lubin-Tate trace compatible sequences are a generalization of norm compatible sequences, which arise in Iwasawa theory and local class field theory. The result we prove generalizes the interpolation theorem proved by Coleman in the classical norm compatible sequence case. We also, jointly with Victor Kolyvagin, give a method for finding such series explicitly in certain special cases.

Elucidating The Roles Of Eukaryotic Initiation Factors Involved In Dap5 Mediated Translation, Jacob Nk Quartey

Dissertations, Theses, and Capstone Projects

Translation initiation in eukaryotes is a highly regulated process essential for accurate protein synthesis. It is a dynamic process that involves a complex interplay between messenger RNAs (mRNAs), ribosomal subunits, and a host of initiation factors, ensuring precise start codon selection and the subsequent assembly of the translation machinery. This process has well been known to be mediated by the eukaryotic Initiation Factor (eIF4F), which consists of the cap binding protein eIF4E, the scaffolding protein eIF4GI, and the helicase factor eIF4A.The recognition and binding of eIF4E to the m⁷G cap structure of the mRNA is essential for the …

The study identified six additional themes: flexible admissions, desire for independence, merit-based …

Decoding The Plant Metabolome: A Metabolomics Approach To Guereza (Colobus Guereza) Feeding Ecology In Kibale National Park, Uganda, Emma Grace Thurau

Dissertations, Theses, and Capstone Projects

Plant metabolites, an elusive and diverse group of plant chemicals, represent a complex chemical interplay between plants and herbivores. Plants contain essential nutrients necessary for herbivore survival, yet herbivore consumption results in negative fitness consequences to a plant. This relationship has triggered a coevolutionary arms race in which plants have evolved chemical defenses to prevent herbivore consumption and herbivores, in response, have evolved their own counter-adaptations. This arms race has led to the diverse numbers of herbivores and plants observed today; therefore, these plant metabolites act as a signature of evolution through their influence on herbivore adaptations. Plant metabolites are …
