Title:  Coding Theory and Subspace codes

Abstract:  In this talk I will give a basic introduction into the ideas of coding theory and subspace codes. Then I will give a few examples of constructions of subspace codes and show a theorem which can be used to link these codes. I will end on the idea of decoding particularly the linkage construction. This should be an introductory talk, no previous coding theory knowledge required.

Title:  A scattering map in two dimensions

Abstract:  We consider the scattering map introduced by Beals and Coifman and Fokas and Ablowitz that may be used to transform one of the Davey-Stewartson equations to a linear evolution. We give mapping properties of this map on weighted L 2 Sobolev spaces that mimic well-known properties of the Fourier transform. This is joint work with N. Serpico, P. Perry and K. Ott.

A special 1-credit opportunity to discover text mining and textual data analysis.

Across many disciplines, interest is increasing in the use of computational text analysis in the service of answering questions in the humanities and the social sciences. Media scientists analyze social media in order to predict corporate crises, political scientists and economists look for indicators of mood and sentiment in platform speeches and economic forecasts, literary scholars analyze the distribution of motifs in large numbers of texts in different literary epochs, and social historians and sociolinguists look for networks and connections among the people, places, and times related to the documents they study.



Following the distinction between "digitized" vs. "digital" scholarship, computers not only assist the work of researchers (digitized scholarship) but also transform the basis of the scholarship: they foster research that would have not been possible without digitization and increasing computing power (digital scholarship). Mapping emotions by mining huge numbers of books, or searching all Latin texts from Antiquity for paraphrases of Plato, are only two examples of investigations documenting the innovative potential of digital research. This transformation makes it necessary to reflect on the new relationship of scholars to their objects of investigation and to discuss the new ways researchers handle textual "data".



In this course we will familiarize ourselves with the concepts, debates, and selected tools within text-based digital scholarship and discuss the repercussions on the way we perceive and construct our objects of research.

Mass surveillance is only possible with the help of smart computer algorithms. Whenever text data is monitored by machines, methods from computational linguistics come into play. The main goal is to automatically filter and identify content that points to certain attitudes or behavioral dispositions viewed as a threat to security. When monitoring online data, the task is even more complicated.  Since people are not usually required to provide their real identity in cyberspace, the tracing of identities through language features ("writeprint") is another challenge for computational linguistics at the service of the intelligence apparatus. Surveillance through language relies on the idea of the expressive function of language: Whenever we utter something, we do not just say something about the world to someone else, we also reveal something about ourselves.

In my talk I will give a critical account of some of the linguistic methods used to automatically attribute identities such as "extremist", "endangerer", or "potential terrorist" on the basis of text analysis. Starting with an overview of the political, legal, and technical framework of state surveillance measures in Germany, I will discuss core concepts of the surveillance discourse and present examples of how linguistic knowledge can be used to assign identities for the purpose of control. In doing so, I hope to foster a discussion on the logic of surveillance in western democracies and the responsibility of the sciences and humanities.

In celebration of the 50th anniversary of the Wilderness Act, the Environmental & Sustainability Studies program at the University of Kentucky will be hosting the movie, Green Fire, on Thursday, October 2nd at 7pm in the Student Center Theater. At the showing Dr. Bob Sandmeyer will discuss Aldo Leopold's role in the establishment of wilderness as a public lands designation as well as the idea of wilderness and its importance to Leopold's land ethic. Discussion will follow the movie.

Recently, unexpected relations between unrelated physical quantities such as Hall viscosity, conductivity and angular momentum have been proposed for certain condensed matter systems with broken parity. We derive the quantum field theory Ward identities originated from area preserving as well as conformal transformations for relativistic as well as non-relativistic systems. The relations among these physical quantities depend on the symmetries of the system. A special cases yields the well known relation: Hall viscosity is half the angular momentum.

Don't miss this opportunity to see and hear the the James Leva Quartet performing A Kindly Visitation, a play about fiddler Tommy Jarrell. This event is free and open to the public!  The performing quartet is James Leva, Riley Baugus, Danny Knicely, and Ira Bernstein. The play starts at 7:30 in the Recital Hall of the Singletary Center for the Arts on Tuesday, October 14, 2014.

Come help SEA (Students of English Association) and members of the English Dept celebrate the National Day of Writing.  For the fourth year in a row, we will be working with the Carnegie Center and running a writing booth in the Student Center.

All English majors and minors are invited to come talk openly with the DUS, Pearl James, and director of Creative Writing, Julia Johnson.  Come have some pizza and tell us about your experience.  What do English majors want? What is working, and what could be improved?  What questions do you have?
