Barrett

Barrett, The Honors College at Arizona State University proudly showcases the work of undergraduate honors students by sharing this collection exclusively with the ASU community.

Barrett accepts high performing, academically engaged undergraduate students and works with them in collaboration with all of the other academic units at Arizona State University. All Barrett students complete a thesis or creative project which is an opportunity to explore an intellectual interest and produce an original piece of scholarly research. The thesis or creative project is supervised and defended in front of a faculty committee. Students are able to engage with professors who are nationally recognized in their fields and committed to working with honors students. Completing a Barrett thesis or creative project is an opportunity for undergraduate honors students to contribute to the ASU academic community in a meaningful way.

Hyperactive ERK/MAPK Regulates Cortical GABAergic Neuron Development

Description
Aberrant signaling through the canonical RAS/RAF/MEK/ERK (ERK/MAPK) pathway leads to the pathology of a group of neurodevelopmental disorders called RASopathies. RASopathies are caused by germline mutations in the ERK/MAPK pathway and have an incidence of approximately 1:2000 births. The majority of RASopathies stem from mutations that cause gain-of-function in the…

Aberrant signaling through the canonical RAS/RAF/MEK/ERK (ERK/MAPK) pathway leads to the pathology of a group of neurodevelopmental disorders called RASopathies. RASopathies are caused by germline mutations in the ERK/MAPK pathway and have an incidence of approximately 1:2000 births. The majority of RASopathies stem from mutations that cause gain-of-function in the ERK/MAPK pathway. In this study, we have begun to unravel the roles that GABAergic interneurons play in the pathology of RASopathies. Our data demonstrate that gain-of-function ERK/MAPK signaling expressed in a GABAergic interneuron-specific fashion leads to forebrain hyperexcitability in mutant mice. Further, some GABAergic interneurons experience activated-caspase 3 mediated apoptosis in the embryonic subpallium, leading to a loss of PV-expressing interneurons in the somatosensory cortex. We found that pharmaceutical intervention during embryogenesis using a MEK1 inhibitor may be effective in preventing apoptosis of these neurons. Future work is still needed to understand the mechanism of the death of GABAergic interneurons and to further pursue therapeutic approaches. Taken together, this study suggests potential roles of cortical GABAergic interneurons in ERK/MAPK-linked pathologies and indicates possible approaches to provide therapy for these conditions.

Energy Subsidies: Cheaper Energy or Energy Abuse?

This paper seeks to analyze the relationship between energy subsidies on fossil fuels by countries and corresponding energy consumption, specifically electricity, by its citizens and occupants. The purpose of this was to determine whether pre-tax subsidies and post-tax subsidies have an effect on that consumption. This paper will discuss the prospect of accounting for post-tax subsidies as a method to curb rampant energy consumption throughout the world, with the focus being on residential electricity use. The two case studies, the Netherlands and Saudi Arabia, will illustrate the consumption patterns in relatively similar economic societies with different subsidy policies. Saudi Arabia will be a high pre-tax subsidy example while the Netherlands will be shown to account for some of the post-tax subsidies through an externality tax system. At the end of this analysis, this paper will show that the heavy subsidization of electricity production is strongly correlated to residential electricity consumption at levels that many officials would deem unsustainable, and that as such, subsidy reform is both beneficial and necessary.

Haiti in Turmoil: Why US Foreign aid has not worked and how to fix it

Description

Countries such as Haiti—where corruption, violence, and extreme poverty hinder economic growth and recovery— require multifaceted, interdisciplinary solutions. The United States, along with much of the western world, has a flawed understanding of foreign aid.

Countries such as Haiti—where corruption, violence, and extreme poverty hinder economic growth and recovery— require multifaceted, interdisciplinary solutions. The United States, along with much of the western world, has a flawed understanding of foreign aid. Though current humanitarian efforts have effectively improved the lives of millions of Haitians, they fail to address the systemic roots of Haiti’s issues. Likewise, some efforts have been counterproductive or even harmful. If the US wishes to assist Haiti (and similar developing countries for that matter) in its journey to restoring the rule of law, reducing corruption, and empowering its citizens, it must collaborate with Haitian leaders and prioritize socioeconomic policy programs.
