Designing Curriculum The Fair Way, Lorraine Wallace

The Utah English Journal

It was my second year as a teacher, my first year in a new school. In early August, I went to the building and introduced myself to the secretary. She was very pleasant as she escorted me to my new classroom. She opened the door, handed me the key, pointed to the cupboards where books were stored, and told me to let her know if I needed anything. Expecting some type of curriculum guide, I naively asked, “What am I supposed to teach?” “English, of course,” she answered with a laugh that continued as she went down the hall, back …

John Jay As A Hispanic-Serving Institution: Meeting The Challenges And Opportunities. A Position Paper, John Jay College Of Criminal Justice - Department Of Latin American And Latina/O Studies, Lisandro Perez, Jose Luis Morin, Isabel Martinez

Reports and Publications from John Jay College

What is true of constitutions is also true of strategic plans: they are just pieces of paper unless we make them real, give them power with the choices we make. The Department of Latin American and Latina/o Studies is presenting this Position Paper to the John Jay College community in the hope and expectation that it will serve as a source of reflection, discussion, and, especially, actions that will lead to fulfilling the College’s obligations and promise as a Hispanic-Serving institution (HSI), in keeping with Goal #5 of the John Jay 2020 Strategic Plan.

Investigation Of Neutron Induced Ternary Fission With The Niffte Time Projection Chamber, Alex C. Kemnitz

Physics

Ternary fission is a rare occurrence in which three particles are produced from a single fission event. This analysis uses tracked fission event data recorded by NIFFTE’s time projection chamber with a series of refined cuts to isolate all possible ternary events. The experiment used two targets, each consisting of two isotopes; one target was Pu-239 and U-235, and the other was U-238 and U-235. The data was used to measure the ternary/binary fission ratios for each isotope. The ratios for the Pu-239 and U-235 target that were found are shown to be too high due to alpha contamination. The …

Multiwavelength Follow-Up Of A Rare Icecube Neutrino Multiplet, Karen Andeen

Physics Faculty Research and Publications

On February 17, 2016, the IceCube real-time neutrino search identified, for the first time, three muon neutrino candidates arriving within 100 s of one another, consistent with coming from the same point in the sky. Such a triplet is expected once every 13.7 years as a random coincidence of background events. However, considering the lifetime of the follow-up program the probability of detecting at least one triplet from atmospheric background is 32%. Follow-up observatories were notified in order to search for an electromagnetic counterpart. Observations were obtained by Swift’s X-ray telescope, by ASAS-SN, LCO and MASTER at optical wavelengths, …

Constraints On Galactic Neutrino Emission With Seven Years Of Icecube Data, Karen Andeen

Physics Faculty Research and Publications

The origins of high-energy astrophysical neutrinos remain a mystery despite extensive searches for their sources. We present constraints from seven years of IceCube Neutrino Observatory muon data on the neutrino flux coming from the Galactic plane. This flux is expected from cosmic-ray interactions with the interstellar medium or near localized sources. Two methods were developed to test for a spatially extended flux from the entire plane, both of which are maximum likelihood fits but with different signal and background modeling techniques. We consider three templates for Galactic neutrino emission based primarily on gamma-ray observations and models that cover a wide …

Faculty Publications

The T2K experiment reports an updated analysis of neutrino and antineutrino oscillations in appearance and disappearance channels. Asample of electron neutrino candidates at Super-Kamiokande in which a pion decay has been tagged is added to the four single-ring samples used in previous T2K oscillation analyses. Through combined analyses of these five samples, simultaneous measurements of four oscillation parameters, j?m2 32j, sin2 ?23, sin2 ?13, and dCP and of the mass ordering are made. A set of studies of simulated data indicates that the sensitivity to the oscillation parameters is not limited by neutrino interaction model uncertainty. Multiple oscillation analyses are …

Internode Morphometrics And Allometry Of Tonkin Cane Pseudosasa Amabilis, Liang Cheng, Cang Hui, Gadi V.P. Reddy, Yu Long Ding, Pei Jian Shi

Faculty Publications

Pseudosasa amabilis (McClure) (Poales: Gramineae) is a typical bamboo species naturally distributed in large area of south China and famous for its culm strength. Although bamboos were found to share the same development rule, the detailed internode morphology of bamboo culm was actually not fully expressed. We explored internode morphology of P. amabilis using 11 different physical parameters in different dimensions (1–4). As Taylor's power law (TPL) is generally applicable to describe relationship between mean and variance of population density, here we used TPL to evaluate the differences between internodes, and further, the relationship between dimension and TPL. Results showed …

Arthropod Development’S Response To Temperature: A Review And New Software For Modeling, Mohammad Ali Mirhosseini, Yaghoub Fathipour, Gadi V.P. Reddy

Faculty Publications

Among environmental factors, temperature has a direct and crucial influence on the key life processes of survival, development, reproduction, and movement of poikilothermic animals and hence their population dynamics. The lower and upper temperature thresholds and optimal temperature have ramifications for all major life processes, where within a specific range, a temperature change results in a proportional rise or fall of the rate of any given process. There are some basic approaches for modeling development response to temperature in arthropods. The oldest and most widely used model is a simple linear description of arthropod development in relation to temperature.The linear …

Comparison Of Thermal Performance Equations In Describing Temperature-Dependent Developmental Rates Of Insects: (Iii) Phenological Applications, Pei Jian Shi, Mei Ling Fan, Gadi V.P. Reddy

Faculty Publications

The developmental times of poikilotherms at different stages are significantly affected by temperature. Most mathematical models describing the temperature-dependent developmental rates of poikilotherms are built according to the experimental data at various constant temperatures. However, these models can also be applied to the developmental rates at variable temperatures. It is more meaningful to use models to predict the occurrence times of pest insects that actually represent the completion for a particular developmental stage (e.g., hatching, pupation, eclosion) under a natural thermal environment. For some developmental stages, insects might experience a period of high temperatures. In this case, skewed bell-shaped nonlinear …

Admixture Mapping In The Hispanic Community Health Study/Study Of Latinos Reveals Regions Of Genetic Associations With Blood Pressure Traits, Tamar Sofer, Leslie J. Baier, Sharon R. Browning, Timothy A. Thornton, Gregory A. Talavera, Sylvia Wassertheil-Smoller, Martha L. Daviglus, Robert Hanson, Sayuko Kobes, Richard S. Cooper, Jianwen Cai, Daniel Levy, Alex P. Reiner, Nora Franceschini

Faculty Publications

Admixture mapping can be used to detect genetic association regions in admixed populations, such as Hispanics/Latinos, by estimating associations between local ancestry allele counts and the trait of interest. We performed admixture mapping of the blood pressure traits systolic and diastolic blood pressure (SBP, DBP), mean arterial pressure (MAP), and pulse pressure (PP), in a dataset of 12,116 participants from the Hispanic Community Health Study/Study of Latinos (HCHS/SOL). Hispanics/Latinos have three predominant ancestral populations (European, African, and Amerindian), for each of which we separately tested local ancestry intervals across the genome. We identified four regions that were significantly associated with …

Let C be an open cone in a Banach space equipped with the Thompson metric with closure a normal cone. The main result gives sufficient conditions for Borel probability measures μ,ν on C with finite first moment for which μ≤ν in the stochastic order induced by the cone to be order approximated by sequences {μn}, {νn} of uniform finitely supported measures in the sense that μn≤νn for each n and μn→μ, νn→ν in the Wasserstein metric. This result is the crucial tool in developing a pathway for extending various inequalities on operator and matrix means, which include the harmonic, geometric, …

Three-Dimensional Quasi-Periodic Shifted Green Function Throughout The Spectrum, Including Wood Anomalies, Oscar P. Bruno, Stephen P. Shipman, Catalin Turc, Stephanos Venakides

Faculty Publications

This work, part II in a series, presents an efficient method for evaluation of wave scattering by doubly periodic diffraction gratings at or near what are commonly called ‘Wood anomaly frequencies’. At these frequencies, there is a grazing Rayleigh wave, and the quasi-periodic Green function ceases to exist. We present a modification of the Green function by adding two types of terms to its lattice sum. The first type are transversely shifted Green functions with coefficients that annihilate the growth in the original lattice sum and yield algebraic convergence. The second type are quasi-periodic plane wave solutions of the Helmholtz …

Semi-Discrete Error Estimates And Implementation Of A Mixed Method For The Stefan Problem, Ch B. Davis, Sh W. Walker

Faculty Publications

We analyze a dual formulation and finite element method for simulating the Stefan problem with surface tension (originally presented in [C.B. Davis and S.W. Walker, Int. Free Bound. 17 (2015) 427-464]). The method uses a mixed form of the heat equation in the solid and liquid (bulk) domains, and imposes a weak formulation of the interface motion law (on the solid-liquid interface) as a constraint. The computational method uses a conforming mesh approach to accurately capture the jump conditions across the interface. Preliminary error estimates are derived, under reduced regularity assumptions, for the difference between the time semi-discrete solution and …

Hydrodynamic And Thermal Effects Of Sub-Critical Heating On Superhydrophobic Surfaces And Microchannels, Adam M. Cowley

Theses and Dissertations

This dissertation focuses on the effects of heating on superhydrophobic (SHPo) surfaces. The work is divided into two main categories: heat transfer without mass transfer and heat transfer in conjunction with mass transfer. Numerical methods are used to explore the prior while experimental methods are utilized for the latter. The numerical work explores convective heat transfer in SHPo parallel plate microchannels and is separated into two stand-alone chapters that have been published archivally. The first considers surfaces with a rib/cavity structure and the second considers surfaces patterned with a square lattice of square posts. Laminar, fully developed, steady flow with …

Results—Dye-conjugated PNAs showed no aggregation under …

Weighting The Perceived Importance Of Minimising Economic, Social And Environmental/Cultural Risks In Flood Risk Management, Zeinab Bedri, John O'Sullivan, Mark Adamson

Conference papers

In 2006, the Office of Public Works (OPW) began the National Catchment-based Flood Risk Assessment and Management (CFRAM) Programme through a series of pilot studies. A Multi-Criteria Analysis (MCA) Framework was developed through the CFRAM pilot studies that integrated a range of objectives related to human health and society, the environment and cultural heritage and the economy into the core process of selecting suitable flood risk management measures for a given area or location, and then for prioritising national investments for different schemes and projects. In support of this MCA framework, UCD, was commissioned to undertake a collaborative study with …

Accessing Blue Spaces: Social And Geographic Factors Structuring Familiarity With, Use Of, And Appreciation Of Urban Waterways, Melissa Haeffner, Douglas Jackson-Smith, Martin Buchert, Jordan Risley

Environmental Science and Management Faculty Publications and Presentations

Are urban waterways amenities, and if so, are there inequities in household access? While urban waterways represent a potential site for access to nature within the urban environment, there have been few studies on the accessibility and interactions with water features in particular, what we refer to as “blue spaces." This study drew on a sample of households in Northern Utah living in neighborhoods with a nearby river or canal to ask if local waterways provide positive impacts to households and if proximity to them increased the likelihood of households spending time at them and being familiar with them. We …

Sbirt Screening In Primary Care Of Women Of Reproductive Age To Aid In The Identification Of Alcohol Use Patterns Focusing On Prevention Of Fetal Alcohol Exposure, Isabel Vesely

Student Projects for Graduate Degrees

The over consumption of alcohol can directly correlate with negative effects on health and quality of life. When vulnerable subjects such as pregnant women and subsequently the fetus is alcohol exposed lifelong detrimental consequences can ensue such as Fetal Alcohol Spectrum Disorder (Jones, Smith, Ulleland, & Streissguth, 1973). Although most women reduce their alcohol intake during pregnancy, 45% of pregnancies in the United States are unplanned (Finer & Zolna, 2016). The combination of social patterns of alcohol use in women of childbearing age and the prevalence of unintended pregnancy set the stage for an alcohol exposed fetus. Late recognition of …

Head Pose Estimation In The Wild Using Convolutional Neural Networks And Adaptive Gradient Methods, M Patacchiola, A Cangelosi

School of Engineering, Computing and Mathematics

Head pose estimation is an old problem that is recently receiving new attention because of possible applications in human-robot interaction, augmented reality and driving assistance. However, most of the existing work has been tested in controlled environments and is not robust enough for real-world applications. In order to handle these limitations we propose an approach based on Convolutional Neural Networks (CNNs) supplemented with the most recent techniques adopted from the deep learning community. We evaluate the performance of four architectures on recently released in-the-wild datasets. Moreover, we investigate the use of dropout and adaptive gradient methods giving a contribution to …
