THE UNFAIR TREATMENT OF CRYPTOCURRENCIES BY THE U.S. INTERNAL REVENUE SERVICE

This paper explores the challenges the cryptocurrency industry has been confronting in the United States due to the unfairness of the tax policies issued by the United States Internal Revenue Service. Cryptocurrency service providers, miners, investors and general consumers are being prevented from taking advantages of special tax treatments as compared to other similar properties, commodities and securities. Tax legislation has not kept pace with the development of emerging cryptocurrency technologies that enable otherwise traditional types of revenue to be generated

New N=4 Superfields and Sigma-models

In this note, we construct new representations of D=2, N=4 supersymmetry which do not involve chiral or twisted chiral multiplets. These multiplets may make it possible to circumvent no-go theorems about N=4 superspace formulations of WZWN-models.Comment: 11 pages, late

Anti-field Formalism and Non-Abelian Duality

The act of implementing non-Abelian duality in two dimensional sigma models results unavoidably in an additional reducible symmetry. The Batalin-Vilkovisky formalism is employed to handle this new symmetry. Valuable lessons are learnt here with respect to non-Abelian duality. We emphasise, in particular, the effects of the ghost sector corresponding to this symmetry on non-Abelian duality.Comment: 13 pages, LaTeX2

The Proceedings of the International Civil Aviation English Association (2019) Conference

Hosted by All Nippon Airways (ANA) in Chiba, Tokyo, Japan, the 2019 International Civil Aviation English Association (ICAEA) annual conference focused on exploring the aviation English training needs of ab-initio pilots and air traffic controllers, as well as aircraft maintenance personnel. Globally, much of the demand for new pilots and air traffic controllers is located in areas of world for which English is not a first or national language. Exploring this resulting need to train non-native English speaking personnel was a primary focus of the 2019 ICAEA conference, including consideration of the language proficiency required for success in initial training, test design and implementation, instructional techniques, and the actual language used by this target population. Further, although the International Civil Aviation Organization (ICAO) Language Proficiency Requirements (LPRs) do not directly apply to maintenance personnel, the widespread use of English in the international aviation maintenance industry necessitates language-training solutions. For the first time, the ICAEA conference included a specific track for presenters to share their knowledge and experience related to training aircraft maintenance personnel which, until now, has been an underrepresented and underdeveloped area of aviation English. The conference featured plenary presentations, Q&A panels, and practical workshops. More than 100 participants from over 35 countries attended ICAEA’s first event in Asia in seven years. Attendees included representatives from airlines, flight training organizations (FTOs), air navigation service providers (ANSPs), civil aviation authorities (CAAs), universities, and training and testing providers from all over the world. These proceedings feature six articles written by seven of the presenters, summarizing their practical experiences and research findings which were shared at the conference. This publication is recommended to anyone interested in aeronautical communication. The accompanying presentation materials, as well as shorter summaries of other presentations and workshops, can be found on Embry-Riddle Aeronautical University’s Scholarly Commons page
