Discrete Geometry and Convexity in Honour of Imre Bárány

This special volume is contributed by the speakers of the Discrete Geometry and Convexity conference, held in Budapest, June 19–23, 2017. The aim of the conference is to celebrate the 70th birthday and the scientific achievements of professor Imre Bárány, a pioneering researcher of discrete and convex geometry, topological methods, and combinatorics. The extended abstracts presented here are written by prominent mathematicians whose work has special connections to that of professor Bárány. Topics that are covered include: discrete and combinatorial geometry, convex geometry and general convexity, topological and combinatorial methods. The research papers are presented here in two sections. After this preface and a short overview of Imre Bárány’s works, the main part consists of 20 short but very high level surveys and/or original results (at least an extended abstract of them) by the invited speakers. Then in the second part there are 13 short summaries of further contributed talks. We would like to dedicate this volume to Imre, our great teacher, inspiring colleague, and warm-hearted friend

Q(sqrt(-3))-Integral Points on a Mordell Curve

We use an extension of quadratic Chabauty to number fields,recently developed by the author with Balakrishnan, Besser and M ̈uller,combined with a sieving technique, to determine the integral points overQ(√−3) on the Mordell curve y2 = x3 − 4

Modeling Narrative Discourse

This thesis describes new approaches to the formal modeling of narrative discourse. Although narratives of all kinds are ubiquitous in daily life, contemporary text processing techniques typically do not leverage the aspects that separate narrative from expository discourse. We describe two approaches to the problem. The first approach considers the conversational networks to be found in literary fiction as a key aspect of discourse coherence; by isolating and analyzing these networks, we are able to comment on longstanding literary theories. The second approach proposes a new set of discourse relations that are specific to narrative. By focusing on certain key aspects, such as agentive characters, goals, plans, beliefs, and time, these relations represent a theory-of-mind interpretation of a text. We show that these discourse relations are expressive, formal, robust, and through the use of a software system, amenable to corpus collection projects through the use of trained annotators. We have procured and released a collection of over 100 encodings, covering a set of fables as well as longer texts including literary fiction and epic poetry. We are able to inferentially find similarities and analogies between encoded stories based on the proposed relations, and an evaluation of this technique shows that human raters prefer such a measure of similarity to a more traditional one based on the semantic distances between story propositions

A Status of NASA Rotorcraft Research

In 2006, NASA rotorcraft research was refocused to emphasize high-fidelity first-principles predictive tool development and validation. As part of this new emphasis, documenting the status of NASA rotorcraft research and defining the state-of-the-art in rotorcraft predictive capability were undertaken. This report is the result of this two-year effort. Contributors to this work encompass a wide range of expertise covering the technical disciplines of aeromechanics, acoustics, computational fluid dynamics (CFD), flight dynamics and control, experimental capabilities, propulsion, structures and materials, and multi-disciplinary analysis

Teaching/Learning Physics: Integrating Research into Practice

The GIREP-MPTL International conference on Teaching/Learning Physics: Integrating Research into Practice [GIREP-MPTL 2014] was held from 7 to 12 July 2014 at the University of Palermo, Italy. The conference has been organised by the Groupe International de Recherche sur l’Enseignement de la Physique [GIREP] and the Multimedia in Physics Teaching and Learning [MPTL] group and it has been sponsored by the International Commission on Physics Education [ICPE] – Commission 14 of the International Union for Pure and Applied Physics [IUPAP], the European Physical Society – Physics Education Division [EPS-PED], the Latin American Physics Education Network [LAPEN] and the Società Italiana di Fisica [SIF]. The theme of the conference, Teaching/Learning Physics: Integrating Research into Practice, underlines aspects of great relevance in contemporary science education. In fact, during the last few years, evidence based Physics Education Research provided results concerning the ways and strategies to improve student conceptual understanding, interest in Physics, epistemological awareness and insights for the construction of a scientific citizenship. However, Physics teaching practice seems resistant to adopting adapting these findings to their own situation and new research based curricula find difficulty in affirming and spread, both at school and university levels. The conference offered an opportunity for in-depth discussions of this apparently wide-spread tension in order to find ways to do better. The purpose of the GIREP-MPTL 2014 was to bring together people working in physics education research and in physics education at schools from all over the world to allow them to share research results and exchange their experience. About 300 teachers, educators, and researchers, from all continents and 45 countries have attended the Conference contributing with 177 oral presentations, 15 workshops, 11 symposia, and around 60 poster presentations, together with 11 keynote addresses (general talks). After the conference, 147 papers have been submitted for the GIREP-MPTL 2014 International Conference proceedings. Each paper has been reviewed by at least two reviewers, from countries that are different to those of the authors and on the basis of criteria described on the Conference web site. Papers were subsequently revised by authors according to reviewers’ comments and the accepted papers are reported in this book, divided in 8 Sections on the basis of the keywords suggested by authors. The other book section (actually, the first one) contains the papers that six of the keynote talkers sent for publication in this Proceedings Book. We would like to thank all the authors that contributed with their papers to the realization of this book and all the referees that with their criticism helped authors to improve the quality of the papers

Teaching as Analogous Personalization: A pragmatic inquiry into expert teachers' process for fostering synchrony in educational dialogs, in post-secondary writing

Descriptive understandings of what human learning is, and so normative expectations of what teachers can and should do as educational leaders, has shifted greatly in society over the past century. The learning metaphors have moved from mechanical transfer to organic transformation; the educational approaches have moved from behavioral response-training to social-emotional facilitating: encouraging students not merely to repeat experts but to think like members in those knowledge-based communities, not merely to mimic disciplines' methods but to participate personally in the ongoing discourse of those fields. In an immediate sense, this shift is progress. Yet, in a larger sense, it is merely cycling back to acknowledge an old and persistent thread of practical wisdom among educators: that people learn complexly as emotional-social-intellectual creatures, and so that a teacher's work is to entice interest and effort, to foster a sense of belonging and trust, and to persuade students toward personally connecting with and valuing those same integral parts of a subject-matter that the teacher has already beneficially personalized for themselves. This longstanding rhetorical and pragmatic view of a teacher's educational role is now being supported directly by empirical research that shows the sense-bound, neurologically integrated, socially attuned, identity-and-meaning motivated character of human feelings, thoughts, and dispositions. I introduce the term “analogous personalization” to capture this synthetic (experience-based, scientifically supported) understanding of teaching as complexly social-emotional, intellectual, persuasive work. I then focus on educational dialogs—specifically within post-secondary writing-based courses—as a means of exploring how expert teachers foster synchrony between their own and their students' personal connections to (i.e., emotional inclination toward, social affiliation with, intellectual/practical understanding of) subject-matter. First, this dissertation offers a synthetic overview of some emergent mind-brain-body findings, and points out the fundamental educational realities that those findings substantiate. On that foundation, it next overviews insights from the field of rhetoric-and-writing about how teachers can usefully conceptualize the learner-knowledge-environment relationship from a dialogic perspective, to achieve effective (intentional, situated, synchronous) educational exchanges. Building from those scientific and practical literatures, it offers a flexible research method for studying the pragmatic arc of an educational exchange (from teacher intention to student take-away): by using the teacher's own personal, practical, principled framework of educational ideals and approaches; comparing their stated intentions with students' stated learning experiences, and tracing the arc of that educational dialog through actual classroom recordings. Finally, it enlists this radically situated research method to analyze three expert university writing teachers' practices: their idiosyncratic understandings of a teacher's role (from their own perspective); their experience-based manner of forming learning-centered relationships with students (from my observing perspective); and their apparent, persuasive self-investment in the course's subject-matter and the students' learning (from students' perspectives). It concludes with observations about the role of a teacher's sincerity (both practiced and perceived) in developing professional expertise and achieving synchrony with students in educational exchanges
