Modeling the Development & Expression of Political Opinion: A Zallerian Approach

Date: 2024-01-01

Creator: Avery C Ellis

Access: Open access

Research focused on John Zaller's famous RAS model of political opinion formation and change from "The Nature and Origins of Mass Opinion" (1992). Analyzed the mathematical and psychological underpinnings of the model, the first paper to do so in over fifteen years and the first to do so through an analysis of motivated reasoning and Bayesian reasoning. Synthesized existing critiques of Zaller's model and other literature to suggest ways to build on Zaller, utilizing fundamental reunderstandings of opinions and messages from political and mathematical perspectives. Found verification for Zaller's model, confirming its value, but also found support for the proposed RAIS model, which suggests foundational changes in the way citizens interact with information in the current political environment. Confirmed the utility of a Zallerian framework for analyzing shifts in mass opinion over time and suggested ways to improve the creation of surveys and polls for understanding elections and reported opinions on issues.

            The role of modulation on the pyloric neurons and the neuromuscular junction in a pattern generator-effector system

            Neuromodulation, the process of altering the electrical outputs of a neuron or neural circuit, allows an organism to control its physiological processes to meet the needs of both its internal and external environments. Previous work shows that the pyloric pattern of the kelp crab (Pugettia producta) stomatogastric nervous system (STNS) neurons responded to fewer neuromodulators than the Jonah crab (Cancer borealis). Since the kelp crab diet primarily eats kelp, it is possible that the movements of the foregut that control digestion may require less flexibility in functional output compared to an opportunistic feeder. To determine whether a reduced flexibility is correlated with diet, this study compared the modulatory responses in Pugettia to two other species of majoid crabs: Chionoecetes opilio and Libinia emarginata, which are both opportunistic feeders. Pooled data for this study found that Libinia and Chionoecetes responded to all twelve modulators tested. When considering the effect of modulators on stomatogastric ganglion (STG) motor outputs, we must consider whether these modulators also alter the excitatory junction potentials (EJPs) at the neuromuscular junction (NMJ), and whether there are differences in responses across species. To test this, the dorsal gastric nerve (dgn) was stimulated while recording intracellularly from the muscle fibers of the associated gm4 muscles. The NMJ of the gm4 in Cancer borealis did not appear to be broadly modulated, as only RPCH and CabTRP showed increases in amplitude, and RPCH decreased facilitation at 5 Hz.

                            New Institutional Economics: Political Institutions and Divergent Development in Costa Rica and Honduras

                            For most of their histories, Costa Rica and Honduras were primarily agricultural societies with little economic diversification. However, around 1990, after the implementation of Washington Consensus reforms, the economies of both nations began to diverge. Costa Rica’s economy rapidly expanded for the following 30 years, while Honduras remained stagnant. Through a New Institutional Economics approach, I argue that institutional differences between Costa Rica and Honduras are responsible for the impressive economic growth Costa Rica has been able to achieve in the past few decades. Specifically, early political developments in Costa Rica have deeply imbedded relatively egalitarian values into the population, helping shape formal and informal inclusive political institutions. Meanwhile, Honduras experienced the development of extractive political institutions, as political and economic power was heavily concentrated in the hands of a select few. These political institutions were crucial during the implementation stages of Washington Consensus reforms, as strong and inclusive political institutions attracted Foreign Direct Investment that helped propel the Costa Rican economy and materialize its position as an outlier in the region. In contrast, lack of institutional guarantees discouraged foreign investors from investing money into the Honduran economy. Through a deep dive into the political histories of both nations, from European discovery to modernity, I conclude that the political institutions of these Central American nations have determined their economic growth paths.
