Harsh Poetry and Art's Address: Romare Bearden and Hans-Georg Gadamer in Conversation

In this essay, I analyze Romare Bearden’s art, methodology, and thinking about art, as well as his attempt to harmonize his personal aesthetic goals with his sociopolitical concerns. I then turn to Hans-Georg Gadamer’s reflections on art and our experience (Erfahrung) of art. I show how Bearden’s approach to art and the artworks themselves resonate with Gadamer’s critique of aesthetic consciousness and his contention that artworks address us, make claims upon us, and even reveal truth. Lastly, I discuss Gadamer’s emphasis on the spectator’s active yet non-mastering role in the event of art’s address—an event that implicates the spectator and has the potential to transform him or her. This leads to a discussion of Gadamer’s notion of the type of self-(and world) understanding that occurs through aesthetic experience. I close by returning to Bearden in order to discuss how his art unearths a crucial feature of our being-in-the-world. I call this feature “world-unmasking” and show how it expands and enriches Gadamer’s account

Interstitial Soundings: Philosophical Reflections on Improvisation, Practice, and Self-Making

In Interstitial Soundings, Cynthia R. Nielsen brings music and philosophy into a fruitful and mutually illuminating dialogue. Topics discussed include the following: music's dynamic ontology, performers and improvisers as co-composers, the communal character of music, jazz as hybrid and socially constructed, the sociopolitical import of bebop, Afro-modernism and its strategic deployments, jazz and racialized practices, continuities between Michel Foucault's discussion of self-making and creating one's musical voice, Alasdair MacIntyre on practice, and how one might harmonize MacIntyre's notion of virtue development with Foucauldian resistance strategies

Strategic Afro-Modernism, Dynamic Hybridity, and Bebop's Socio-Political Significance

In this chapter, I argue that one can articulate a historically attuned and analytically rich model for understanding jazz in its various inflections. That is, on the one hand, such a model permits us to affirm jazz as a historically conditioned, dynamic hybridity. On the other hand, to acknowledge jazz’s open and multiple character in no way negates our ability to identify discernible features of various styles and aesthetic traditions. Additionally, my model affirms the sociopolitical, legal (Jim Crow and copyright laws), and economic structures that shaped jazz. Consequently, my articulation of bebop as an inflection of Afromodernism highlights the sociopolitical, and highly racialized context in which this music was created. Without a recognition of the sociopolitical import of bebop, one’s understanding of the music is impoverished, as one fails to grasp the strategic uses to which the music and discourses about the music were put

A model for J/ψJ/\psi - kaon cross section

We calculate the cross section for the dissociation of $J/\psi$ by kaons within the framework of a meson exchange model. We find that, depending on the values of the coupling constants used, the cross section can vary from 5 mb to 30 mb at $\sqrt{s}\sim5$ GeV.Comment: 4 pages, 3 eps figure

The performance of a combined solar photovoltaic (PV) and thermoelectric generator (TEG) system

The performance of a combined solar photovoltaic (PV) and thermoelectric generator (TEG) system is examined using an analytical model for four different types of commercial PVs and a commercial bismuth telluride TEG. The TEG is applied directly on the back of the PV, so that the two devices have the same temperature. The PVs considered are crystalline Si (c-Si), amorphous Si (a-Si), copper indium gallium (di)selenide (CIGS) and cadmium telluride (CdTe) cells. The degradation of PV performance with temperature is shown to dominate the increase in power produced by the TEG, due to the low efficiency of the TEG. For c-Si, CIGS and CdTe PV cells the combined system produces a lower power and has a lower efficiency than the PV alone, whereas for an a-Si cell the total system performance may be slightly increased by the TEG.Comment: 10 pages, 6 figure

Duality of privacy amplification against quantum adversaries and data compression with quantum side information

We show that the tasks of privacy amplification against quantum adversaries and data compression with quantum side information are dual in the sense that the ability to perform one implies the ability to perform the other. These are two of the most important primitives in classical information theory, and are shown to be connected by complementarity and the uncertainty principle in the quantum setting. Applications include a new uncertainty principle formulated in terms of smooth min- and max-entropies, as well as new conditions for approximate quantum error correction.Comment: v2: Includes a derivation of an entropic uncertainty principle for smooth min- and max-entropies.
