Fearless Friday: Yasmine Perry

This Friday, we are celebrating the work of Yasmine Perry ’17. Yasmine, who is originally from Orange, New Jersey, is a senior at Gettysburg College and is majoring in English and minoring in Math. Currently, she is involved with the Black Student Union (BSU) and the Social Entrepreneurship Initiative (SEI), which is a year-long program at Gettysburg College that aims to enable students to impact positive change in their communities, countries, and around the world through social entrepreneurship. Yasmine is also a program coordinator with the Center for Public Service (CPS), working specifically with the LIU Migrant Education program. This Spring Break, she will also be leading an immersion trip to León, Nicaragua, which will focus on education, literacy, and community development. [excerpt

Effective Generation of Subjectively Random Binary Sequences

We present an algorithm for effectively generating binary sequences which would be rated by people as highly likely to have been generated by a random process, such as flipping a fair coin.Comment: Introduction and Section 6 revise

On infinite words avoiding a finite set of squares

Building an infinite square-free word by appending one letter at a time while simultaneously avoiding the creation of squares is most likely to fail. When the alphabet has two letters this approach is impossible. When the alphabet has three or more letters, one will most probably create a word in which the addition of any letter invariably creates a square. When one restricts the set of undesired squares to a finite one, this can be possible. We study the constraints on the alphabet and the set of squares which permit this approach to work.Comment: 18 page

Everyday writing in Graeco-Roman and late antique Egypt : outline of a new research programme

In October 2017, the European Research Council awarded a Starting Grant to Klaas Bentein for his project EVWRIT: Everyday writing in Graeco-Roman and Late Antique Egypt: A socio-semiotic study of communicative variation. In what follows, the research goals, methodology, and corpus of this new project are briefly outlined

On the hypersurface orbital varieties of sl(N,C)

We study the structure of hypersurface orbital varieties of sl(N,C) (those that are hypersurfaces in the nilradical of some parabolic subalgebra) and how information about this structure is encoded in the standard Young tableau associated to it by the Robinson-Schensted algorithm. We present a conjecture for the exact form of the unique non-linear defining equations of hypersurface orbital varieties and proofs of the conjecture in certain cases.Comment: 17 page

The US-China Trade Conflict: A Game Theoretical Analysis

Game Theory has been gaining great importance in Economics, encouraging research in many theoretical and applied fields. This paper relies on simple game theory tools to set up a major international trade dispute. Using the backward deduction approach, the strategies of the United States and China in their recent trade conflict are analyzed.Trade Conflict, Exchange Rate Policy, Game Theory
