Connections Between Classical And Parametric Network Entropies, Matthias Dehmer, Abbe Mowshowitz, Frank Emmert-Streib
Connections Between Classical And Parametric Network Entropies, Matthias Dehmer, Abbe Mowshowitz, Frank Emmert-Streib
Publications and Research
This paper explores relationships between classical and parametric measures of graph (or network) complexity. Classical measures are based on vertex decompositions induced by equivalence relations. Parametric measures, on the other hand, are constructed by using information functions to assign probabilities to the vertices. The inequalities established in this paper relating classical and parametric measures lay a foundation for systematic classification of entropy-based measures of graph complexity.

\African-Centered Psychology, Education And The Liberation Of African Minds: Notes On The Psycho-Cultural Justification For Reparations, Karanja Keita Carroll, Dereef F. Jamison
Publications and Research
One means through which reparations can be provided to communities of African descent within America is through the creation and institutionalization of culturally enriching after-school programming, African-centered Saturday schools and independent Black educational institutions. Rather than looking to reparations as merely financial compensation for the descendants of the formerly enslaved, we can look to reparations as they relate to the building of educational infrastructures that will impact future generations of African descendants in America. This essay outlines the psychological and epistemological consequences of miseducation that many students of African descent experience within the Eurocentrically orientated education institutions they attend; The …
Flight Control Design For A Tailless Aircraft Using Eigenstructure Assignment, Clara Nieto-Wire, Kenneth Sobel
Flight Control Design For A Tailless Aircraft Using Eigenstructure Assignment, Clara Nieto-Wire, Kenneth Sobel
Publications and Research
We apply eigenstructure assignment to the design of a flight control system for a wind tunnel model of a tailless aircraft. The aircraft, known as the innovative control effectors (ICEs) aircraft, has unconventional control surfaces plus pitch and yaw thrust vectoring. We linearize the aircraft in straight and level flight at an altitude of 15,000 feet and Mach number 0.4. Then, we separately design flight control systems for the longitudinal and lateral dynamics. We use a control allocation scheme with weights so that the lateral pseudoinputs are yaw and roll moment, and the longitudinal pseudoinput is pitching moment. In contrast …

Publications and Research
Information retrieval has become very popular over the last decade with the advent of the Web. Nevertheless, searching on the Web is very different to searching on smaller, often more structured collections such as digital libraries, local Web sites and intranets. One way of helping the searcher locating the right information for a specific information need is by providing well-structured domain knowledge to assist query modification and navigation. There are two challenges: acquiring the domain knowledge and adapting it automatically to the specific interests of the user community. We will outline how a domain model can be automatically acquired using …
Learning Through Quests And Contests: Games In Information Literacy Instruction, Maura A. Smale
Learning Through Quests And Contests: Games In Information Literacy Instruction, Maura A. Smale
Publications and Research
Games-based learning is an innovative pedagogical strategy employed at all levels of education, and much research in education, psychology, and other disciplines supports its effectiveness in engaging and motivating students, as well as increasing student learning. Many libraries have incorporated games into their collections and program-ming. College and university libraries have begun to use games for information literacy and library instruction. Academic librarians use commercially-produced games, create their own games, and employ game principles and mechanics to enhance their tradi-tional instructional offerings. While there may be impediments to implementing games-based learning for information literacy, the promising benefits of this approach …
Climate Change: The Fork At The End Of Now, Micha Tomkiewicz
Climate Change: The Fork At The End Of Now, Micha Tomkiewicz
Publications and Research
There are many books on global warming written entirely from a layman's perspective, and there is a great deal of scientific literature on this subject. But few if any books attempt to bridge the science to those who lack a rigorous background in mathematics, physics and chemistry-but who may be working on careers in environmental science and policy. The new text is designed to introduce the field of global climate change from a scientific perspective-but written in a way that is accessible to students with some or little science background. It reviews the basic principles of climatic thermodynamics and atmospheric …
Teacher Collaboration: Implications For New Mathematics Teachers, Laura M. Gellert, Lidia Gonzalez
Teacher Collaboration: Implications For New Mathematics Teachers, Laura M. Gellert, Lidia Gonzalez
Publications and Research
One increasingly popular way of supporting new teachers is through the use of mentoring. New teachers are often paired with mentors as one of a number of supports meant to aid new teachers as they begin their career. The various types of mentoring range from school based mentors assigned by the school to specialty mentors, such as math coaches. Examples of other types of supports that are thought of as separate from formal mentoring are lesson studies, professional development schools, professional development workshops supported by local universities, teacher networks and sponsored professional development. Given the popularity of policies promoting support …

The Maximum Rectilinear Crossing Number Of The Wheel Graph, Elie Feder
Publications and Research
We find and prove the maximum rectilinear crossing number of the wheel graph. First, we illustrate a picture of the wheel graph with many crossings to prove a lower bound. We then prove that this bound is sharp. The treatment is divided into two cases for n even and n odd.

Dissipative Macroscopic Quantum Tunneling In Type-I Superconductors, Ricardo Zarzuela, Eugene M. Chudnovsky, Javier Tejada
Dissipative Macroscopic Quantum Tunneling In Type-I Superconductors, Ricardo Zarzuela, Eugene M. Chudnovsky, Javier Tejada
Publications and Research
We study macroscopic quantum tunneling of interfaces separating normal and superconducting regions in type-I superconductors. Mathematical model is developed, that describes dissipative quantum escape of a two-dimensional manifold from a planar potential well. It corresponds to, e.g., a current-driven quantum depinning of the interface from a grain boundary or from artificially manufactured pinning layer. Effective action is derived and instantons of the equations of motion are investigated. Crossover between thermal activation and quantum tunneling is studied and the crossover temperature is computed. Our results, together with recent observation of non-thermal low-temperature magnetic relaxation in lead, suggest possibility of a controlled …
A Bulk Inflaton From Large-Volume Extra Dimensions, Brian Greene, Daniel N. Kabat, Janna Levin, Dylan Thurston
A Bulk Inflaton From Large-Volume Extra Dimensions, Brian Greene, Daniel N. Kabat, Janna Levin, Dylan Thurston
Publications and Research
The universe may have extra spatial dimensions with large volume that we cannot perceive because the energy required to excite modes in the extra directions is too high. Many examples are known of such manifolds with a large volume and a large mass gap. These compactifications can help explain the weakness of four-dimensional gravity and, as we show here, they also have the capacity to produce reasonable potentials for an inflaton field. Modeling the inflaton as a bulk scalar field, it becomes very weakly coupled in four dimensions, and this enables us to build phenomenologically acceptable inflationary models with tunings …

Publications and Research
The Spitzer-SDSS-GALEX Spectroscopic Survey (SSGSS) provides a new sample of 101 star-forming galaxies at z < 0.2 with unprecedented multi-wavelength coverage. New mid- to far-infrared spectroscopy from the Spitzer Space Telescope is added to a rich suite of previous imaging and spectroscopy, including ROSAT, Galaxy Evolution Explorer, Sloan Digital Sky Survey, Two Micron All Sky Survey, and Spitzer/SWIRE. Sample selection ensures an even coverage of the full range of normal galaxy properties, spanning two orders of magnitude in stellar mass, color, and dust attenuation. In this paper we present the SSGSS data set, describe the science drivers, and detail the sample selection, observations, data reduction, and quality assessment. Also in this paper, we compare the shape of the thermal continuum and the degree of silicate absorption of these typical, star-forming galaxies to those of starburst galaxies. We investigate the link between star formation rate, infrared luminosity, and total polycyclic aromatic hydrocarbon luminosity, with a view to calibrating the latter for spectral energy distribution models in photometric samples and at high redshift. Last, we take advantage of the 5-40 micron spectroscopic and far-infrared photometric coverage of this sample to perform detailed fitting of the Draine et al. dust models, and investigate the link between dust mass and star formation history and active galactic nucleus properties.

Mount Graham, in southern Arizona, is considered a sacred location by the Apaches. The remoteness and high elevation of the mountain makes it an ideal location for astronomical research. After protracted litigation suits, the University of Arizona prevailed and was allowed to establish the Mount Graham International Observatory on the site.

Introduction To Gis Using Open Source Software, 1st Ed, Frank Donnelly
Open Educational Resources
This tutorial was created to accompany the GIS Practicum, a day-long workshop offered by the Newman Library at Baruch College CUNY that introduces participants to geographic information systems (GIS) using the open source software QGIS. The practicum introduces GIS as a concept for envisioning information and as a tool for conducting geographic analyses and creating maps. Participants learn how to navigate a GIS interface, how to prepare layers and conduct a basic geographic analysis, and how to create thematic maps. This tutorial was written using QGIS version 1.5 "Tethys", a cross-platform (Windows, Mac, Linux) desktop GIS software package.

Six Titans Of The Cambridge School: A Review Article, Harvey Gram
Publications and Research
Six volumes in the Great Thinker in Economics Series were chosen by the Editors for this review, which focuses on The Cambridge School of Economics, so very different from the mainstream theory of general economic equilibrium which gives formal expression to Lionel Robbins’ famous definition of the subject as the allocation of scarce means among alternative uses. In recognition of a distinct Cambridge School, the authors of these volumes present a variety of arguments within which three overlapping themes can be discerned: the relationship between ethics and economics; the role of stocks and flows in economic analysis; and the epistemic …

Dea With A Perfect Object: Analytical Solutions, Alexander Vaninsky
Publications and Research
For the main DEA models, adding a Perfect Object—that is, a virtual object that has the smallest inputs and greatest outputs—to a collection of actual objects permits obtaining solutions analytically. The paper derives formulas for the solutions and demonstrates that computations with them comprise simple operations with ratios of inputs and outputs while avoiding the use of linear programming (LP) algorithms. A numerical example illustrates the utility of the approach.
