Proteomic Approaches To Investigate Pp2a-B55 Substrates And Cellular Function, Brennan C. Mcewan

Dartmouth College Ph.D Dissertations

Cell division is controlled in large part by reversible protein phosphorylation. The phosphorylation state of proteins during mitosis and other phases of the cell cycle represents a careful balance of activity between kinases and opposing phosphatases. The phosphoprotein phosphatase (PPP) family is responsible for the majority of serine and threonine dephosphorylation. Members of the PPP family are composed of a catalytic subunit paired with a regulatory subunit that targets them towards specific substrates.

The most abundant PPP, PPP2A, paired with its regulatory B55 subunit, is thought to be the phosphatase responsible for the dephosphorylation of substrates during mitotic exit. Despite …

Examining Choices Of Sarcastic Responses In Dialogue With Virtual Interlocutors, Samantha Langley

Theses and Dissertations

We report the results from three experiments examining people’s preferences for using sarcasm in conversation as a function of: 1. whether their interlocutor uses sarcasm during the conversation; 2. Their knowledge about whether the interlocutor has used sarcasm in a previous conversation; 3. The presence of prosodical and visual cues for interlocutors’ sarcasm. In each experiment, participants took part in two conversations, and we manipulated whether the interlocutors were sincere or sarcastic and whether they remained the same or changed from one conversation to the next. Experiment one used written conversations and experiment two and three used pre-recorded video clips …

Rethinking Equality In Mathematics Education With Category Theory, Kelly Paton

The Mathematics Enthusiast

To provide an alternative to the flattening operations of equality, which are prevalent not only in mathematics but also in our everyday world, I introduce the relational structures of category theory and their more nuanced notions of equivalence. Instead of defaulting to a binary assignation of equal or not-equal, equivalence posits that contextual relationships are integral to how we conceive of ‘same’ and ‘different’. I draw upon the ideas of philosophers who work against the erasure of diversity and offer ways to uphold difference while searching for commonalities. As I trace the sociopolitical implications of embracing an ontological framework built …

Environmental Receipts: The Ecological Footprint Of Multilateral Development Banks, Mike Wigdor

Student Publications

This paper assesses whether membership in multilateral development banks (MDBs) is associated with lower ecological footprints. Drawing on country-year data from the 2025 Quality of Government (QoG) Basic Dataset and the Correlates of War (CoW) IGO Dataset, I analyze 1,714 observations from 1970–2008. Ecological footprint (global hectares per capita) is used as the dependent variable, while the central explanatory variable is the total number of MDB memberships annually. I utilize an OLS regression model controlling for logged GDP per capita, regime type, oil production value, urbanization, and economic globalization. Contrary to my hypothesis that MDB safeguards, norm diffusion, and pooling …

Gillooly, Robert Bagchi, Joseph A. Lamanna, Daniel J. Johnson

Biological Sciences Faculty Research and Publications

The Janzen-Connell Hypothesis posits that plant species diversity is maintained by a reduction in seedling survival near living conspecific trees relative to heterospecifics–known as negative conspecific density dependence (CDD). CDD facilitates coexistence if stronger than heterospecific density dependence (HDD). However, whether and how long CDD persists after trees die is unknown. In a three-year study across three forests, we monitored seedling survival near living and dead trees, both conspecific and heterospecific, across a seven-year chrono-sequence since tree death. CDD persisted for at least 5 years after tree death (‘legacy CDD’), and most species showed stronger CDD relative to HDD through …

Morphology-Performance Relationships To Understand Cichlid Neurocranial Evolution In The Context Of Adaptive Radiation, Sarah Pascarella

Theses and Dissertations from DePaul University

Cichlid fishes have undergone multiple adaptive radiations in the rift lakes of East Africa pairing rapid taxonomic and morphological diversification. Lake Malawi’s rock-dwelling cichlids (mbuna) have diversified into hundreds of species that partition their habitat by depth and diet resulting in high morphological and behavioral diversity. We characterized morphological differences and performed behavioral assays among four cichlid genera from Lake Malawi focused on understanding form-function relationships in the neurocranium and oral feeding apparatus. We characterized neurocranial shape using 3D geometric morphometrics across a large taxonomic sample of mbuna cichlids, focusing primarily on the Tropheops species complex. Alongside broad changes in …

Toward The Human Right To Water For Vulnerable Communities: The Effectiveness Of Stakeholder Processes To Control Regional Shallow Groundwater Contamination By Nitrates, Iris Stewart, John Dialesandro, Samantha Lei, Lilah Foster

Environmental Studies and Sciences

Nitrate contamination in shallow drinking water wells is an urgent and persistent concern for agricultural regions and disadvantaged communities worldwide. As viable options for the large-scale removal of nitrates from groundwater remain elusive, greater emphasis has been placed on stakeholder-based integrative approaches, yet few have been developed, and fewer evaluated for their effectiveness. The Central Valley in California is one of the most important intensive agricultural regions globally, where such a stakeholder-based process (CV-SALTS) has been initiated, and which is poised to serve as a model for controlling nitrate contamination elsewhere. Based on the Groundwater Ambient Monitoring and Assessment Program …

(Si15-093) Dynamics Of The Generalized Nonlinear Schrödinger Equation With A Source Using An Analytical Method, Manish Raghav, Manoj .

Applications and Applied Mathematics: An International Journal (AAM)

In the present article, an analytical method is used to obtain hyperbolic, trigonometric, and rational solutions of the generalized nonlinear Schrödinger (GNLS) equation with a source. The ability of solitons to preserve their shapes during propagation makes them suitable for optical fiber communication. Solutions to the generalized nonlinear Schrödinger equation with a source can also describe solitons, and understanding their dynamics helps to design communication systems based on solitons. The analytical method used is compelling and effective for finding exact solutions to various nonlinear evolution equations (NLEEs). To further understand the phenomena, we create 3−D, contour, and 2−D graphs of …
