    Steven D. Vance Research Focus My research focuses on using geophysical and geochemical methods to understand ocean worlds: how oceans couple to the thermal evolution and composition, and what this might mean for life. I am also interested in the global geochemical fluxes in ocean worlds, by analogy to biogeochemical fluxes in the Earth system. My experimental research involves collecting thermodynamic equations of state for fluids and ices. I have applied these equations of state to evaluating oceanic heat transport and double diffusive convection in Europa, and to the geophysical constraints imposed by ocean composition on the radial structures of Europa, Ganymede, Callisto, Enceladus, and Titan. In recent years I have used these models to explore the parameter space of possible geophysical signals—seismic, magnetic, and gravitational—in the interest of improving the fidelity of returned science from investigations of ocean composition and habitability.

    EXPLORING MIDDLE GRADE TEACHERS’ KNOWLEDGE OF PARTITIVE AND QUOTITIVE FRACTION DIVISION by SOO JIN LEE (Under the Direction of Denise S. Mewborn) ABSTRACT The purpose of the present qualitative study was to investigate middle grades (Grade 5-7) mathematics teachers’ knowledge of partitive and quotitive fraction division. Existing research has documented extensively that preservice and inservice teachers lack adequate preparation in the mathematics they teach (e.g., Ball, 1990, 1993). Especially, research on teachers’ understanding of fraction division (e.g., Ball, 1990; Borko, 1992; Ma, 1999; Simon, 1993) has demonstrated that one or more pieces of an ideal knowledge package (Ma, 1999) for fraction division is missing. Although previous studies (e.g., Ball, 1990; Borko, 1992; Ma, 1999; Simon, 1993; Tirosh & Graeber, 1989) have stressed errors and constraints on teachers’ knowledge of fraction division, few studies have been conducted to explore teachers’ knowledge of fraction division at a fine-grained level (Izsák, 2008). Thus, I concentrated on teachers’ operations and flexibilities with conceptual units in partitive and quotitive fraction division situations. Specifically, I attempted to develop a model of teachers’ ways of knowing fraction division by observing their performance through a sequence of division problems in which the mathematical relationship between the dividend and the divisor became increasingly complex. This is my first step toward building a learning trajectory of teachers’ ways of thinking, which can be extremely useful for thinking about how to build an effective professional development program and a teacher education program. The theoretical frame that I developed for this study emerged through analyses of teachers’ participation in the professional development program where they were encouraged to reason with/attend to quantitative units using various drawings such as length and area models.

Its initial terms are 1, 9, 7, 17, 33, 57, 107, 197, 361, 665,... Note that 197 itself is a member of this sequence. This phenomenon was first noticed by Mike Keith and such numbers are now called Keith numbers.

    Idiopathy: A Novel and ‘A Failed Entertainment:’ The Process of Paying Attention in and to Infinite Jest by Sam Byers Thesis submitted for the qualification of Doctor of Philosophy at The University of East Anglia, Department of Literature, Drama, and Creative Writing, September 2013. © This copy of the thesis has been supplied on condition that anyone who consults it is understood to recognize that its copyright rests with the author and that use of any information derived there from must be in accordance with current UK Copyright Law. In addition, any quotation or extract must include full attribution. WORD COUNT: 90,000 words + Appendix 2 Abstract My PhD thesis combines a novel, Idiopathy, and a critical essay, ‘A Failed Entertainment:’ The Process of Paying Attention In and To Infinite Jest. Idiopathy examines the inner lives of three friends and their experiences of both separation and a reunion. By emphasising internality over externality it seeks to examine the notion that how we feel about our lives may be more important, indeed, more ‘real,’ than what takes place around us. Idiopathy is overtly concerned with the extent to which interaction with others is problematic, and pays particular attention to the emotional complexities of friendships, relationships and family dynamics. Through these pained and frequently unsatisfactory interactions the novel seeks to satirise broader social phenomena, such as media panics, health epidemics, ideological protest movements and the rise of what might be termed a ‘pathologised’ culture, in which all the characters are continually concerned that something is ‘wrong’ with them. Illness is a metaphor throughout, and is explored not only through the characters’ sense of personal malaise, but also through the device of a fictional cattle epidemic that forms a media backdrop to unfolding events.

  • Section Handout
    CS106B Handout 11 Autumn 2012 October 1st, 2012 Section Handout This first week, I’m only including two problems, because introductions might take 15 or so of the 50 minutes we have. One of the problems is a discussion problem, and the other is written up as an informal coding exercise. However, I’ll always allow your section leader and your peers to decide if you’d rather adopt the collaborative discussion-problem format for both of them. Discussion Problem 1: Publishing Stories Social networking sites like Facebook, LinkedIn, and Google+ typically record and publish stories about actions taken by you and your friends. Stories like: Jessie Duan accepted your friend request. Matt Anderson is listening to Green Day on Spotify. Patrick Costello wrote a note called "Because Faiz told me to". David Wang commented on Jeffrey Spehar’s status. Mike Vernal gave The French Laundry a 5-star review. are created from story templates like {name} accepted your friend request. {name} is listening to {band} on {application}. {name} wrote a note called "{title}". {name} commented on {target}’s status. {actor} gave {restaurant} a {rating}-star review. The specific story is generated from the skeletal one by replacing the tokens—substrings like "{name}", "{title}", and "{rating}"—with event-specific values, like "Jessie Duan", "Because Faiz told me to", and "5". The token-value pairs can be packaged in a Map<string, string>, and given a story template and a data map, it’s possible to generate an actual story. 2 Write the generateStory function, which accepts a story template (like "{actor} gave {restaurant} a {rating}-star review.") and a Map<string, string> (which might map "actor" to "Mike Vernal", "restaurant" to "The French Laundry", and "rating" to "5"), and builds a string just like the story template, except the tokens have been replaced by the text they map to.

ORESTE PIRO and IDAN TUVAL Institut Mediterrani d’Estudis Avanc¸ats, CSIC–UIB, E-07071 Palma de Mallorca, Spain. Received (received date) Revised (revised date) Accepted (accepted date) We review the concept of bailout embedding; a general process for obtaining order from chaotic dy- namics by embedding the system within another larger one. Such an embedding can target islands of order and hence control chaos. Moreover, a small amount of noise enhances this process. Keywords: Bailout embedding, emergence in noisy environments, noise-induced patterns, noisy self- organization 1. Introduction “But how does it happen,” I said with admiration, “that you were able to solve the mystery of the library looking at it from the outside, and you were unable to solve it when you were inside?” “Thus God knows the world, because He conceived it in His mind, as if from the outside, before it was created, and we do not know its rule, because we live inside it, having found it already made.” Dialogue between Adso and William, in Umberto Eco’s The Name of the Rose, Third Day: Vespers. Many times we have a given system, we want to study it or modify its behaviour, but we cannot get inside. We are thus obliged to do so from the outside.

  • Solving Knapsack and Related Problems
    Solving knapsack and related problems Daniel Lichtblau Wolfram Research, Inc. 100 Trade Centre Dr. Champaign IL USA, 61820 [email protected] Abstract. Knapsack problems and variants thereof arise in several different fields from operations research to cryptography to really, really serious problems for hard−core puzzle enthusiasts. We discuss some of these and show ways in which one might formulate and solve them using Mathematica. 1. Introduction A knapsack problem is described informally as follows. One has a set of items. One must select from it a subset that fulfills specified criteria. A classical example, from cryptosystems, is what is called the "subset sum" problem. From a set S of numbers, and a given number k, find a subset of S whose sum is k. A variant is to find a subset whose sum is as close as possible to k. Another variant is to allow integer multiples of the summands, provided they are small. That is, we are to find a componentwise "small" vector v such that v.S » k (where we regard S as being an ordered set, that is, a vector). More general knapsack problems may allow values other than zero and one (typically selected from a small range), inequality constraints, and other variations on the above themes.. Of note is that the general integer linear programming problem (ILP) can be cast as a knapsack problem provided the search space is bounded. Each variable is decomposed into new variables, one for each "bit"; they are referred to as 0 −1 variables because these are the values they may take.

  • I ABSTRACT a CONCEPTUAL MODEL of ICE SHELF
    i ABSTRACT A CONCEPTUAL MODEL OF ICE SHELF SEDIMENTATION Matthew Mayerle, M.S. Department of Geology and Environmental Geosciences Northern Illinois University 2014 Ross Powell, Director Sedimentation studies of polar glacimarine systems remain few relative to temperate glacimarine systems due to the problem of accessibility below ice shelves. This thesis presents a conceptual model of ice shelf sedimentation at the scale of a continental shelf, which is an update of Howat and Domack’s (2003) model. This update adds scale, a third dimension, a decade of research on new geologic/glaciological processes, depositional bias', and greater specificity to their model. The shelf-scale model groups facies into deformation till, glacigenic debris flows, shelfstone mud, and diatomaceous mud. Furthermore, the model is tested and shown to be capable of replicating the facies distribution and major landforms found in two distinctly different Antarctic paleo-ice stream troughs within time constraints dictated by radiometric dating. It is hoped that ideas and techniques presented by this conceptual model will serve as a launching pad for more advanced computational models in the future, which are badly needed in order to help constrain future behavior of ice sheets in a warming world. i NORTHERN ILLINOIS UNIVERSITY DE KALB, ILLINOIS DECEMBER 2014 A CONCEPTUAL MODEL OF ICE SHELF SEDIMENTATION BY MATTHEW WILLIAM MAYERLE ©2014 Matthew Mayerle A THESIS SUBMITTED TO THE GRADUATE SCHOOL IN PARTIAL FULLFILLMENT OF THE REQUIREMENTS FOR THE DEGREE OF MASTER OF SCIENCE DEPARTMENT OF GEOLOGY AND ENVIRONMENTAL GEOSCIENCES Thesis Director: Ross D.
