Management Of Bayberry In Relation To Tree-Swallow Strikes At John F. Kennedy International Airport, New York, Glen E. Bernhardt, Zachary J. Paton, Lisa A. Kutschbach-Brohl, Richard A. Dolbeer

Human–Wildlife Interactions

Tree swallows (Tachycineta bicolor) have been a periodic bird-strike problem at John F. Kennedy International Airport (JFKIA), New York, New York, causing runway closures, flight delays, and damage to aircraft following the ingestion of bird flocks into engines. We examined 65 tree swallows collected at JFKIA in October 2001 to determine food sources that were attracting the birds to the airport. Digestive tracts of all 65 specimens contained northern bayberry fruits (Myrica pensylvanica), averaging 15.6 fruits per bird or 3.4% of the bird’s body mass in specimens where the entire tract was dissected. Bayberry fruits are …

Setting Research Priorities At Wildlife Services’ National Wildlife Research Center, Richard L. Bruggers

Human–Wildlife Interactions

As director of the Wildlife Services’ National Wildlife Research Center (NWRC), I frequently have been asked how the NWRC determines, prioritizes, and implements its research agenda. To answer this question, I will start by giving both a historical overview and an update of the NWRC. The mission of the NWRC is to provide science-based tools and information to resolve human–wildlife conflicts.

Observations Of Neck-Collared Canada Geese Near John F. Kennedy International Airport, New York, Thomas W. Seamans, Scott E. Clemons, Allen L. Gosser

Human–Wildlife Interactions

Canada geese (Branta canadensis) often cause significant damage when they strike aircraft. They are responsible for a reported minimum of $2.6 million in damage per year to civil aviation in the United States. Knowledge of goose movements in relation to airports would allow wildlife managers to allocate time and funds to manage those populations that pose the greatest threat to aircraft. We placed alpha-numeric neck collars on 300 Canada geese within 8 km of both John F. Kennedy International Airport (JFKIA) and LaGuardia Airport in New York, New York. We conducted weekly observations for 2 years within a …

Developing Bird-Strike Risk Assessment Models For Open-Water Restorations, Justin D. Hart, Alison Colyer, John R. Allan

Human–Wildlife Interactions

Mineral extraction sites that are restored to open water can increase bird-strike risk if they are planned near airports. This can generate conflict between the minerals industry and safeguarding authorities. To help resolve this potential conflict, it would be useful to predict how new restorations affect local water-bird populations so that mineral deposits can be exploited and restored in safeguarded zones without compromising flight safety. Bird abundances and movements at new restorations can be estimated with statistical models that use the environmental characteristics of restoration schemes as predictor variables. These models can improve guidance in safeguarding, provided that they comprise …

Deep Rationality: The Evolutionary Economics Of Decision Making, Douglas T. Kenrick, Vladas Griskevicius, Jill M. Sundie, Norman P. Li, Jessica Yexin Li, Steven L. Neuberg

Research Collection School of Social Sciences

What is a “rational” decision? Economists traditionally viewed rationality as maximizing expected satisfaction. This view has been useful in modeling basic microeconomic concepts, but falls short in accounting for many everyday human decisions. It leaves unanswered why some things reliably make people more satisfied than others, and why people frequently act to make others happy at a cost to themselves. Drawing on an evolutionary perspective, we propose that people make decisions according to a set of principles that may not appear to make sense at the superficial level, but that demonstrate rationality at a deeper evolutionary level. By this, we …

Compromising Anonymous Communication Systems Using Blind Source Separation, Ye Zhu, Riccardo Bettati

Electrical and Computer Engineering Faculty Publications

We propose a class of anonymity attacks to both wired and wireless anonymity networks. These attacks are based on the blind source separation algorithms widely used to recover individual signals from mixtures of signals in statistical signal processing. Since the philosophy behind the design of current anonymity networks is to mix traffic or to hide in crowds, the proposed anonymity attacks are very effective. The flow separation attack proposed for wired anonymity networks can separate the traffic in a mix network. Our experiments show that this attack is effective and scalable. By combining the flow separation method with frequency spectrum …

Touring Polygamous Utah With Elizabeth W. Kane, Winter 1872–1873, Lowell C. Bennion, Thomas R. Carter

BYU Studies

This article, originally a lecture given at Brigham Young University in 2009, was published as part of a special issue of BYU Studies featuring Thomas L. Kane. Although Kane was not a member of The Church of Jesus Christ of Latter-day Saints, he was an advocate for the Mormon cause and a trusted friend of Mormon leaders for almost forty years. Bennion and Carter consider the ideas presented by Elizabeth Kane, Thomas's wife, who expressed her dismay with plural marriage in her writings about her visit to Utah in 1872–73. The authors combine Elizabeth's views with their interest in Mormon …

Fast And Robust Techniques For The Euclidean P-Median Problem With Uniform Weights, G J. Lim, J Reese, Allen G. Holder

Mathematics Faculty Research

We discuss new solution techniques for the p-median problem, with the goal being to improve the solution time and quality of current techniques. In particular, we hybridize the discrete Lloyd algorithm and the vertex substitution heuristic. We also compare three starting point techniques and present a new solution method that provides consistently good results when appropriately initialized.

The findings of the study indicate that professional pilot faculty take a range of occupational and educational pathways to reach their positions in …

A Comparison Of Algorithms That Estimate The Effectiveness Of Commercial Airline Boarding Strategies, Dalila Giraldo

Doctoral Dissertations and Master's Theses

The number of passengers carried by commercial aircraft has increased dramatically over the past 50 years, closely in-step with advances in aircraft design. This makes unloading and loading an aircraft, called turn-around time, critical to the success of the airport, the aircraft and the airlines. A number of mathematical algorithms have been developed over the years that purport to determine the most efficient boarding strategy for passengers by decreasing turn time. This thesis evaluated the boarding strategies most often used by the airlines and algorithms used to predict boarding efficiency. The models used were obtained from the literature and from …

Q-Groupoids And Their Cohomology, Rajan Amit Mehta

Mathematics Sciences: Faculty Publications

We approach Mackenzie's L{script}A{script}-groupoids from a supergeometric point of view by introducing Q-groupoids, which are groupoid objects in the category of Q-manifolds. There is a faithful functor from the category of L{script}A{script}-groupoids to the category of Q-groupoids. We associate to every Qgroupoid a double complex that provides a model for the Q-cohomology of the classifying space. As examples, we obtain models for equivariant Q-and orbifold Q-cohomology, and for equivariant Lie algebroid and orbifold Lie algebroid cohomology. We obtain double complexes associated to Poisson groupoids and groupoid-algebroid "matched pairs".

Barriers And Bridges To Success: Factors For Retention Of Nontraditional Mexican American Students In Teacher Education, Gail Shroyer, Sally Yahnke, Amanda Morales, Cindi Dunn, Gayla Lohfink, Pedro Espinoza

Department of Teaching, Learning, and Teacher Education: Faculty Publications

This paper discusses the findings of a qualitative, microethnographic case study of 15 nontraditional, Mexican American students as they completed their coursework in a 2+2 teacher education program in the Midwest. The theoretical frameworks that serve as the basis of this study are Tinto’s Model of Student Integration (Tinto, 1975, 1993), Bean’s attrition model (1980), and von Destinon’s empowerment model (1988). This integrated framework is an inclusive adaptation as it addresses the complex interaction among first-generation, Mexican American students’ backgrounds, geographical locations, and the institutions that serve them. The researchers identify characteristics of those students who persisted on to graduation, …

Universal Design, Education And Technology, Ciaran O'Leary, Damian Gordon

9th. IT & T Conference

Universal Design is an approach to design which insists upon the consideration of users with diverse levels of ability. Rather than representing a specialist approach to design, it is recognised that Universal Design results in a better design for all. Furthermore, by isolating design for disability as an independent topic in education, or ignoring it altogether, educators create an exclusionist perception of the role and place of individuals with disability in modern society. Modern education programmes which teach design skills are enhanced in quality by mainstreaming Universal Design as a core topic, permeating all that surrounds it. This paper describes …

Comparison Of Feature Classification Algorithm For Activity Recognition Based On Accelerometer And Heart Rate Data, Dominic Maguire, Richard Frisby

9th. IT & T Conference

This paper describes a project to compare two feature classification algorithms used in activity recognition in relation to accelerometer and heart rate data. Data was collected from six male and female subjects using a single tri-axial accelerometer and heart monitor attached to each subject’s dominant thigh. Subjects carried out eight activities and the data was labelled semi-automatically. Features (mean, standard deviation, energy, correlation and mean heart rate) were extracted from the data using a window of 256 (3.4 seconds) and an overlap of 50%. Two classifers, k-NN and J48, were evaluated for activity recognition with 10-fold validation with k-NN (k …

Vocate: Auditory Interfaces For The Lok8 Project, John Mcgee, Charlie Cullen

9th. IT & T Conference

The auditory modality has a number of unique advantages over other modalities, such as a fast neural processing rate and focus-independence. As part of the LOK8 project’s aim to develop location-based services, the Vocate module will be seeking to exploit these advantages to augment the overall usability of the LOK8 interface and also to deliver scalable content in scenarios where the user may be in transit or requires focus-independence. This paper discusses these advantages and outlines three possible approaches that the Vocate module may take within the LOK8 project: speech interfaces, auditory user interfaces, and sonification.

Tracker: Indoor Positioning For The Lok8 Project, Viacheslav Filonenko, James Carswell

9th. IT & T Conference

Spatial awareness is identified as a key feature of today’s mobile devices. While outdoor navigation has been accessible and broadly used for some time already with the help of GPS, indoor positioning has not yet made it into mainstream life. GPS and other GNSS systems offer accuracy of a scale different to that required for efficient indoor navigation. This research aims to investigate how a number of sensors such as a Digital Compass, Bluetooth and Accelerometer may be combined to calculate device position and orientation to perform directional querying in a spatial database. These three technologies were chosen because they …

Herbert, Matt J. Jarvis, Shanil Virani, Dan Andreescu, Steven P. Bamford, Kate Land, Phil Murray, Robert C. Nichol, M. Jordan Raddick, Anže Slosar, Alex Azalay, Jan Vandenberg

Physics

We report the discovery of an unusual object near the spiral galaxy IC 2497, discovered by visual inspection of the Sloan Digital Sky Survey (SDSS) as part of the Galaxy Zoo project. The object, known as Hanny's Voorwerp, is bright in the SDSS g band due to unusually strong [O iii]4959, 5007 emission lines. We present the results of the first targeted observations of the object in the optical, ultraviolet and X-ray, which show that the object contains highly ionized gas. Although the line ratios are similar to extended emission-line regions near luminous active galactic nucleus (AGN), the source of …

Thermodynamics Of The Quantum Critical Point At Finite Doping In The Two-Dimensional Hubbard Model Studied Via The Dynamical Cluster Approximation, K. Mikelsons, Ehsan Khatami, D. Galanakis, A. Macridin, J. Moreno, M. Jarrell

Faculty Publications

We study the thermodynamics of the two-dimensional Hubbard model within the dynamical cluster approximation. We use continuous time quantum Monte Carlo as a cluster solver to avoid the systematic error which complicates the calculation of the entropy and potential energy (double occupancy). We find that at a critical filling, there is a pronounced peak in the entropy divided by temperature, S/T, and in the normalized double occupancy as a function of doping. At this filling, we find that specific heat divided by temperature, C/T, increases strongly with decreasing temperature and kinetic and potential energies vary like T2 ln T. These …

Funny Money: How Federal Education Funding Hurts Poor And Minority Students, Cassandra Jones Havard

All Faculty Scholarship

Neither race nor class alone can predict educational achievement. However, in America, disparities in funding for education may be an impediment to educational opportunity for disadvantaged youth. At the crux of the Nation's achievement gap among minority children is the question of the how states should allocate federal education funds, and how local school districts should use those monies. Educators have long recognized that the socioeconomic circumstances of many public school students present great educational challenges. Since 1965, Congress has authorized the use of federal funds by local school districts to remedy the achievement gap.

The Attractors Of Teaching Biology: A Perspective From A Turkish Context, Ahmet Kilinc, Ahmet Mahiroglu

Australian Journal of Teacher Education

Because the teaching occupation plays a crucial role in a country’s development, policymakers and teacher recruitment units all around the world strive to understand how to attract individuals to this profession. However, research regarding the attractors of teaching has been conducted almost entirely in developed countries and has not focused on particular subject areas to be taught. In addition, only limited lists of attractors have been used. Accordingly, the main purpose of this study was to examine what attractors influence people who choose teaching biology as a career, and what about the Turkish culture has caused people to make this …

E-Portfolios As A Pedagogical Device In Primary Teacher Education: The Aut University Experience, Marguerite Maher, Philippa Gerbic

Australian Journal of Teacher Education

Portfolios have a long tradition in teacher education and now these are available in electronic form. At the same time, there are increasing demands for primary teachers to be technologically capable and confident in classrooms. When teacher educators wish to respond through the introduction of new technologies such as e-portfolios, there are significant issues of professional learning. This paper discusses one response, a collaborative self-study, around the introduction of an e-portfolio as a pedagogical device. It highlights two key aspects of the study: first, it considers how collaborative self-study as a methodology proved crucial for sustaining lecturer motivation and commitment …

How Can Preservice Teachers Be Measured Against Advocated Professional Teaching Standards?, Peter Hudson

Australian Journal of Teacher Education

Australia has had many inquiries into teaching and teacher education over the last decade. Standards for teaching have been produced by national education systems with many state systems following suit. The Queensland College of Teachers (QCT) advocates ten professional teaching standards for teachers and preservice teachers. How can preservice teachers be measured against advocated professional standards? This study investigated 106 second-year preservice teachers’ perceptions of their development against the QCT standards. A pretest-posttest survey instrument was developed based on the QCT standards and administered to these preservice teachers before and after their science education coursework. Percentages, ANOVAs and t-tests were …

Two-Loop Soft Anomalous Dimensions With Massive And Massless Quarks, Nikolaos Kidonakis

Faculty Articles

I present results for two-loop soft anomalous dimensions, which are derived from dimensionally regularized diagrams with eikonal quark lines and control soft-gluon emission in hard-scattering processes. Detailed results for the UV poles of the eikonal integrals are shown for massive quarks, and the massless limit is also taken. The construction of soft anomalous dimensions at two-loops allows soft-gluon resummations at NNLL accuracy.
