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.
The twin spot generator for differential Drosophila lineage analysis

- In Drosophila melanogaster, widely used mitotic recombination-based strategies generate mosaic flies with positive readout for only one daughter cell after division. To differentially label both daughter cells, we developed the twin spot generator (TSG) technique, which through mitotic recombination generates green and red twin spots that are detectable after the first cell division as single cells. We propose wide applications of TSG to lineage and genetic mosaic studies.
The tyrosine kinase Abl and its substrate enabled collaborate with the receptor phosphatase Dlar to control motor axon guidance

- Genetic analysis of growth cone guidance choice points in Drosophila identified neuronal receptor protein tyrosine phosphatases (RPTPs) as key determinants of axon pathfinding behavior. We now demonstrate that the Drosophila Abl tyrosine kinase functions in the intersegmental nerve b (ISNb) motor choice point pathway as an antagonist of the RPTP Dlar. The function of Abl in this pathway is dependent on an intact catalytic domain. We also show that the Abl phosphoprotein substrate Enabled (Ena) is required for choice point navigation. Both Abl and Ena proteins associate with the Dlar cytoplasmic domain and serve as substrates for Dlar in vitro, suggesting that they play a direct role in the Dlar pathway. These data suggest that Dlar, Abl, and Ena define a phosphorylation state-dependent switch that controls growth cone behavior by transmitting signals at the cell surface to the actin cytoskeleton.

- PREMISE: Biological invasions increasingly threaten native biodiversity and ecosystem services. One notable example is the common reed, Phragmites australis, which aggressively invades North American salt marshes. Elevated atmospheric CO2 and nitrogen pollution enhance its growth and facilitate invasion because P. australis responds more strongly to these enrichments than do native species. We investigated how modifications to stomatal features contribute to strong photosynthetic responses to CO2 and nitrogen enrichment in P. australis by evaluating stomatal shifts under experimental conditions and relating them to maximal stomatal conductance (gwmax) and photosynthetic rates. METHODS: Plants were grown in situ in open-top chambers under ambient and elevated atmospheric CO2 (eCO2) and porewater nitrogen (Nenr) in a Chesapeake Bay tidal marsh. We measured light-saturated carbon assimilation rates (Asat) and stomatal characteristics, from which we calculated gwmax and determined whether CO2 and Nenr altered the relationship between gwmax and Asat. RESULTS: eCO2 and Nenr enhanced both gwmax and Asat, but to differing degrees; gwmax was more strongly influenced by Nenr through increases in stomatal density while Asat was more strongly stimulated by eCO2. There was a positive relationship between gwmax and Asat that was not modified by eCO2 or Nenr, individually or in combination. CONCLUSIONS: Changes in stomatal features co-occur with previously described responses of P. australis to eCO2 and Nenr. Complementary responses of stomatal length and density to these global change factors may facilitate greater stomatal conductance and carbon gain, contributing to the invasiveness of the introduced lineage.

Living Upstream: Kennebec River Influence on Nutrient Regimes and Phytoplankton Communities in Harpswell Sound
Date: 2020-01-01
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.
