Mémoire et souvenir dans l'imaginaire antillais - Maryse Condé et Fabienne Kanor: Identité et existence noire aux Antilles et en France
Date: 2020-01-01
Creator: Elijah B Koblan-Huberson
Access: Open access
- L’histoire d’un peuple est en grande partie liée à sa mémoire, aux souvenirs et commémorations des évènements passés et des ancêtres.En raison de la colonisation et ses conséquences, les habitants des îles de la Guadeloupe et de la Martinique vivent un malaise vis-à-vis de la mémoire en tant que peuple antillais.Par conséquent, il est important de se demander comment, après la déshumanisation effectuée par l’extermination des premiers habitants, les Caraïbes et les Arawaks, l’esclavagisation des Africains, et la colonisation des territoires antillais, une nouvelle conceptualisation de la mémoire peut mener à une nouvelle conceptualisation de l’existence et de l’identité pour l’être humain antillais qui provient de ceux qui ont été esclavagisés. Pour répondre à la question nous examinerons les romans de Maryse Condé et de Fabienne Kanor.
Enemy Combatants and Unitary Executives: Presidential Power in Theory and Practice During the War on Terror
Date: 2020-01-01
Creator: Rohini Kurup
Access: Open access
- In the wake of the September 11 attacks, the Bush administration decided that suspected terrorists and those determined to have aided terrorists would be detained and classified as “enemy combatants.” This was a largely new category of prisoners who were neither prisoners of war protected under international law nor civilians. They included noncitizens and citizens—those captured on foreign battlefields and on American soil. They would be detained by the United States, held indefinitely without charge or access to a lawyer, and subject to trial by military commission. The administration’s enemy combatant policies were based on a theory of inherent executive power—that the Constitution gave the president vast and exclusive powers, which allowed him to act unilaterally without Congressional interference or judicial review. This thesis charts the development of and challenges to the enemy combatant policies to understand how they were conceived and what their implications are to the American political system. I argue that by appealing to a theory of inherent executive power to create the policies, the administration subverted traditional checks on presidential power and undermined the rule of law. Ultimately, the dismantling of some of the enemy combatant policies, largely a result of court rulings that challenged the administration’s premise of power, signified a reining in of executive authority. Yet, many aspects of the administration’s counterterrorism apparatus remained past Bush’s years in the White House, leaving a legacy of expanded presidential power for future presidents.

The role of behavioral diversity in determining the extent to which central pattern generators are modulated
Date: 2020-01-01
Creator: Jacob Salman Kazmi
Access: Open access
- Neuromodulation may be a substrate for the evolution of behavioral diversity. The extent to which a central pattern generator is modulated could serve as a mechanism that enables variability in motor output dependent on an organism’s need for behavioral flexibility. The pyloric circuit, a central pattern generator in the crustacean stomatogastric nervous system (STNS), stimulates contractions of foregut muscles in digestion. Since neuromodulation enables variation in the movements of pyloric muscles, more diverse feeding patterns should be correlated with a higher degree of STNS neuromodulation. Previous data have shown that Cancer borealis, an opportunistic feeder, is sensitive to a wider array of neuromodulators than Pugettia producta, a specialist feeder. The observed difference in modulatory capacity may be coincidental since these species are separated by phylogeny. We predict that the difference in modulatory capacity is a product of a differential need for variety in foregut muscle movements. This study examined two members of the same superfamily as P. producta, the opportunistically feeding snow crab (Chionoecetes opilio) and portly spider crab (Libinia emarginata). Using extracellular recording methods, the responses of isolated STNS preparations to various neuromodulators were measured. Initial qualitative results indicate that the STNS of C. opilio is sensitive to all of these neuromodulators. Additionally, previous data on the neuromodulatory capacity of L. emarginata was supported through similar electrophysiological analysis of the isolated STNS. As a first step in determining the mechanism of differential sensitivity between species, tissue-specific transcriptomes were generated and mined for neuromodulators.

Hermeneutic Encounters: Hans-Georg Gadamer in North America, 1968-1986
Date: 2020-01-01
Creator: Ian Ward
Access: Open access
- Hans-Georg Gadamer’s myriad contributions to the continental philosophical tradition have been well documented, but his influence on North American intellectual life has gone largely gone unrecognized. This paper attempts to fill that gap, using primary and secondary source material to document Gadamer’s scholarly activities in the United States and Canada between 1968 and 1986. The paper also evaluates Gadamer’s influence using detailed accounts of “hermeneutic encounters” that occurred between Gadamer and four notable North American philosophers: Richard Palmer, Paul de Man, Charles Taylor, and Richard Rorty. Through these accounts, this paper argues that Gadamer made lasting contributions to ongoing debates in the humanities about the nature of literary interpretation, the social sciences, and analytic philosophy. Finally, the paper explores the philosophical and historiological possibilities that Gadamer’s hermeneutics opens up for intellectual history more broadly, especially in the field of reception history. Building on Gadamer’s own hermeneutics and Hans-Robert Jauss’s reception aesthetics, it develops the concept of the “encounter” as the starting point of a more hermeneutically-sensitive approach to intellectual history.
Living Upstream: Kennebec River Influence on Nutrient Regimes and Phytoplankton Communities in Harpswell Sound

Creator: Siena Brook Ballance
Access: Open access
- Phytoplankton underpin marine trophic systems and biogeochemical cycles. Estuarine and coastal phytoplankton account for 40-50% of global ocean primary productivity and carbon flux making it critical to identify sources of variability. This project focuses on the Kennebec River and Harpswell Sound, a downstream, but hydrologically connected coastal estuary, as a case study of temperate river influence on estuarine nutrient regimes and phytoplankton communities. Phytoplankton pigments and nutrients were analyzed from water samples collected monthly at 8 main-stem rivers stations (2011-2013) and weekly in Harpswell Sound (2008-2017) during ice-free months. Spatial bedrock and land use impacts on river nutrients were investigated at sub-watershed scales using GIS. Spatial analysis reveals a 10-fold increase in measured phytoplankton biomass across the Kennebec River’s saltwater boundary, which demonstrates ocean-driven phytoplankton variability in the lower river. The biomass pattern is accompanied by a transition in phytoplankton community structure with respect to which groups co-occur (diatoms, chlorophytes, and cryptophytes) and which are unique (dinoflagellates in Harpswell). Upstream, the timing of each community depends on land-use proximity and seasonal discharge. In Harpswell Sound, the nutrient regime and phytoplankton community structure vary systematically: first diatoms strip silicate, then dinoflagellates utilize nitrate, followed by chlorophytes and cryptophytes that utilize available phosphate. These findings reveal, for the first time, patterns in phytoplankton communities and nutrient dynamics across the fresh to salt water interface. Ultimately the Kennebec River phytoplankton communities and nutrient regimes are distinct, and the river is only a source of silicate to Harpswell Sound.

The Colombo-Venezuelan Border Through the Lens of the Colombian Press
Date: 2020-01-01
Creator: Diego Rafael Grossmann
Access: Open access
- The Colombo-Venezuelan Border Through the Lens of the Colombian Press examines the dominant Colombian press coverage of crises of sovereignty at the Colombo-Venezuelan border, Venezuelan migration, and the February 2019 attempt to introduce humanitarian aid into Venezuela, as seen in El Espectador and El Tiempo’s coverage from the period of August 2018-November 2019. Through theories of nations and power, this thesis reveals the divergent editorial lines and dominant narratives within each newspaper’s construction of the relation between the Colombian and Venezuelan nations, states, and their people. The study details how both newspapers construct different “truths” through divergent constructions of similar events in a manner coherent with the ideological affinities and conceptions of Colombian national identity held by their respective audiences and editorial leadership, constrained further by economic factors. The thesis is split into three main chapters. Chapter 1 addresses the construction of Colombian nationhood rooted in militarism and the presentation of the Colombian state as a protector in El Tiempo’s coverage concerning binational tensions at the border. Chapter 2 traces the coverage regarding Venezuelan migration to Colombia within El Espectador, detailing the conception of national identity rooted in liberal-democratic values that the newspaper constructs and appeals to. Chapter 3 considers both newspaper’s coverage of the attempt to introduce humanitarian aid into Venezuela in 2019. Ultimately, this thesis argues that the discursive actor––and construction––of Venezuela permits the “imagining” of the Colombian nation, a project framed through a discussion of the Colombian conflict and official commitments to multiculturalism by the Colombian state.
