Criminal Careers In Cyberspace: Examining Website Failure Within Child Exploitation Networks, Bryce G. Westlake, Martin Bouchard

Bryce Garreth Westlake

Publically accessible, illegal, websites represent an additional challenge for control agencies, but also an opportunity for researchers to monitor, in real time, changes in criminal careers. Using a repeated measures design, we examine evolution in the networks that form around child exploitation (CE) websites, over a period of 60 weeks, and determine which criminal career dimensions predict website failure. Network data were collected using a custom-designed web-crawler. Baseline survival rates were compared to networks surrounding (legal) sexuality and sports websites. Websites containing CE material were no more likely to fail than comparisons. Cox regression analyses suggest that increased volumes of …

Comparing The Model-Simulated Global Warming Signal To Observations Using Empirical Estimates Of Unforced Noise, Patrick T. Brown, Wenhong Li, Eugene C. Cordero, Steven A. Mauget

Eugene C. Cordero

The comparison of observed global mean surface air temperature (GMT) change to the mean change simulated by climate models has received much public and scientific attention. For a given global warming signal produced by a climate model ensemble, there exists an envelope of GMT values representing the range of possible unforced states of the climate system (the Envelope of Unforced Noise; EUN). Typically, the EUN is derived from climate models themselves, but climate models might not accurately simulate the correct characteristics of unforced GMT variability. Here, we simulate a new, empirical, EUN that is based on instrumental and reconstructed surface …

Imbalances And Inequities: The Structure Of Inquiry And Its Place In Rhetorical Studies, Kathleen F. Mcconnell

Kathleen F McConnell

Inquiry’s place in rhetorical studies has long been contentious. Critics argue that academic professionalism and the rise of criticism and theory have diminished rhetoric as a pragmatic art. The recent trend in higher education toward greater restrictions on academic inquiry poses new problems for rhetorical studies, particularly where those restrictions exacerbate existing educational inequities. In the effort to address those inequities, a distinction needs to be made between old concerns with inquiry and the new issues any reorganization of inquiry will present. The generic support for inquiry that universities provide benefits rhetorical studies by lending structure to inquiry processes fraught …

Birds Of A Feather (Les Oiseaux De Même Plumage): Dynamic Soundscapes Using Real-Time Manipulation Of Locally Relevant Birdsongs, William Walker, Brian Belet

Brian Belet

This paper and live audio demonstration explores the capabilities of using Web Audio API as a digital audio workstation (DAW) to manipulate sounds from massive server-side databases. Sonic source material comes from a database of birdsongs recorded worldwide by volunteer recordists at xeno-canto.org. Sounds from xeno-canto are chosen to match recent, nearby bird sightings submitted by volunteer birders at eBird. The result is a virtual soundscape derived from the sounds of birds currently present in the user’s geographical region. Our client-server architecture delegates database queries and archival storage to the server, leaving the client to concentrate on the aesthetic context …

Cultural Norms Of Clinical Simulation In Undergraduate Nursing Education, Susan G. Mcniesh

Susan McNiesh

Simulated practice of clinical skills has occurred in skills laboratories for generations, and there is strong evidence to support high-fidelity clinical simulation as an effective tool for learning performance-based skills. What are less known are the processes within clinical simulation environments that facilitate the learning of socially bound and integrated components of nursing practice. Our purpose in this study was to ethnographically describe the situated learning within a simulation laboratory for baccalaureate nursing students within the western United States. We gathered and analyzed data from observations of simulation sessions as well as interviews with students and faculty to produce a …

Optimal Ranking Regime Analysis Of Intra- To Multidecadal U.S. Climate Variability. Part I: Temperature, Eugene C. Cordero, Steven A. Mauget

Eugene C. Cordero

The optimal ranking regime (ORR) method was used to identify intradecadal to multidecadal (IMD) time windows containing significant ranking sequences in U.S. climate division temperature data. The simplicity of the ORR procedure’s output—a time series’ most significant nonoverlapping periods of high or low rankings—makes it possible to graphically identify common temporal breakpoints and spatial patterns of IMD variability in the analyses of 102 climate division temperature series. This approach is also applied to annual Atlantic multidecadal oscillation (AMO) and Pacific decadal oscillation (PDO) climate indices, a Northern Hemisphere annual temperature (NHT) series, and divisional annual and seasonal temperature data during …

Optimal Ranking Regime Analysis Of Intra- To Multidecadal U.S. Climate Variability. Part Ii: Precipitation And Streamflow, Steven A. Mauget, Eugene C. Cordero

Eugene C. Cordero

In Part I of this paper, the optimal ranking regime (ORR) method was used to identify intradecadal to multidecadal (IMD) regimes in U.S. climate division temperature data during 1896–2012. Here, the method is used to test for annual and seasonal precipitation regimes during that same period. Water-year mean streamflow rankings at 125 U.S. Hydro-Climatic Data Network gauge stations are also evaluated during 1939–2011. The precipitation and streamflow regimes identified are compared with ORR-derived regimes in the Pacific decadal oscillation (PDO), the Atlantic multidecadal oscillation (AMO), and indices derived from gridded SST anomaly (SSTA) analysis data. Using a graphic display approach …

Querie: Collaborative Database Exploration, Magdalini Eirinaki, Suju Abraham, Neoklis Polyzotis, Naushin Shaikh

Magdalini Eirinaki

Interactive database exploration is a key task in information mining. However, users who lack SQL expertise or familiarity with the database schema face great difficulties in performing this task. To aid these users, we developed the QueRIE system for personalized query recommendations. QueRIE continuously monitors the user’s querying behavior and finds matching patterns in the system’s query log, in an attempt to identify previous users with similar information needs. Subsequently, QueRIE uses these “similar” users and their queries to recommend queries that the current user may find interesting. In this work we describe an instantiation of the QueRIE framework, where …

Anger Problems And Posttraumatic Stress Disorder In Male And Female National Guard And Reserve Service Members, Miranda E. Worthen, Sujit D. Rathod, Gregory Cohen, Laura Sampson, Robert Ursano, Robert Gifford, Carol Fullerton, Sandro Galea, Jennifer Ahern

Miranda E. Worthen

Anger is a common problem among veterans and has been associated with posttraumatic stress disorder (PTSD). This study aimed to improve understanding of how anger and PTSD co-occur by examining gender differences and differences by whether the triggering traumatic event is deployment-related vs. civilian-related in current service members. A representative cohort of Reserve and National Guard service personnel (n = 1293) were interviewed to assess for deployment- or civilian-related traumas, PTSD, and anger. The prevalence of self-reported anger problems was estimated among male (n = 1036) and female (n = 257) service members. Log Poisson regression models with robust standard …

Leveraging Scholarships To Advance Student Success, Jared Tuberty, Thalia Anagnos, Emily L. Allen

Thalia Anagnos

As college costs rise, students and their families continually look for ways to pay for an undergraduate education. Increased financial pressures have forced some students to work additional hours in part-time or even full-time employment. As a result, time to degree can be extended as students tackle fewer units per term or as they repeat courses, struggling to balance work and school. Scholarship funding is one mechanism to help support students, but providing financial relief is not enough. Scholarship recipients face many of the same challenges as all students, in that some find themselves struggling as they transition to college …

Formative Assessment In Seven Good Moves, Brent M. Duckor

Brent M. Duckor

The research is clear: What teachers do in their classrooms matters. But which practices really make a difference? John Hattie (2012) conducted an extensive meta-analysis, looking at 800 meta-analyses that focused on locating a specific student achievement outcome and identifying an influence on that outcome. Formative assessment topped his list of the most influential practices that improve student outcomes. What makes formative assessment so effective? It depends on whom you talk to. Although experts tell us that formative assessment is one of the most powerful ways to raise student achievement (Black & Wiliam, 1998), we don't always know which practices …

Results Of Environmental Scanning Applied To The Design Of A Deer Management Decision Support System (Dss) For The United States And California, G. Kent Webb

G. Kent Webb

Using freely available internet search tools for environmental scanning, information related to deer management was collected, categorized, and evaluated with the goal of providing public decision support. Key issues raised in the public debate discovered by the search are addressed with relevant information formatted as output for a decision support system – dashboard elements. A graph addresses contradictory reports about the current direction of the deer population; the trend since 2006 appears to be down. Another graph illustrates the approximate longterm population trend; the current U.S. white-tailed deer population is about the same as in 1500. A table summarizes profiles …

Impact Of Engineering Ambassador Programs On Student Development, Thalia Anagnos, Alicia Lyman-Holt, Claudia Marin-Artieda, Ellen Momsen

Thalia Anagnos

This study highlights the positive impact of participation in an engineering ambassador program on students from two universities: Oregon State University which is a large public university in a college town with a 13% minority student body, and Howard University, a medium sized private university with a relatively small engineering program in an urban setting enrolling a primarily minority population. Although these ambassador programs have a major goal of service to the university and engineering program, they serve an equally important goal of developing the skills and attitudes of the ambassadors themselves. Ambassadors from both universities were surveyed, and though …

Ultra Compact Dwarfs In The Core Of The Perseus Cluster: Ucd Formation Via Tidal Stripping, S. J. Penny, D. A. Forbes, J. Strader, C. Usher, J. P. Brodie, Aaron J. Romanowsky

Aaron J. Romanowsky

We present the results of a Keck/DEIMOS survey of Ultra Compact Dwarfs (UCDs) in the Perseus Cluster core. We confirm cluster membership for 14 UCDs, with radial velocities ~5300 km s−1. Two of these confirmed Perseus UCDs have extremely blue colours (B−R<0.6 mag), reside in star forming filaments surrounding NGC 1275, and have likely formed as massive star clusters in the last ~100 Myr. We also measure a central velocity dispersion of a third, UCD13 (σ0=38±8 km s−1), the most extended UCD in our sample. We determine it to have radius Re=85±1.1 pc, a dynamical mass of (2.3±0.8)×108 M⊙, and a metallicity [Z/H]=−0.52+0.33−0.29 dex. UCD13 and the cluster's central galaxy, NGC 1275, have a projected separation of 30 kpc and a radial velocity difference of ~20 km s−1. Based on its size, red colour, internal velocity dispersion, dynamical mass, metallicity and proximity to NGC 1275, we argue that UCD13 is likely the remnant nucleus of a tidally stripped dE, with this progenitor dE having MB≈−16 mag and mass ∼109 M⊙.

Low Mach Number Fluctuating Hydrodynamics Of Diffusively Mixing Fluids, Aleksandar Donev, Andy J. Nonaka, Yifei Sun, Thomas Fai, Alejandro Garcia, John B. Bell

Alejandro Garcia

We formulate low Mach number fluctuating hydrodynamic equations appropriate for modeling diffusive mixing in isothermal mixtures of fluids with different density and transport coefficients. These equations eliminate the fast isentropic fluctuations in pressure associated with the propagation of sound waves by replacing the equation of state with a local thermodynamic constraint. We demonstrate that the low Mach number model preserves the spatio-temporal spectrum of the slower diffusive fluctuations. We develop a strictly conservative finite-volume spatial discretization of the low Mach number fluctuating equations in both two and three dimensions. We construct several explicit Runge-Kutta temporal integrators that strictly maintain the …

The Sluggs Survey: Breaking Degeneracies Between Dark Matter, Anisotropy And The Imf Using Globular Cluster Subpopulations In The Giant Elliptical Ngc 5846, N. R. Napolitano, V. Pota, Aaron J. Romanowsky, D. A. Forbes, J. P. Brodie, C. Foster

Aaron J. Romanowsky

We study the mass and anisotropy distribution of the giant elliptical galaxy NGC 5846 using stars, as well as the red and blue globular cluster (GC) subpopulations. We break degeneracies in the dynamical models by taking advantage of the different phase space distributions of the two GC subpopulations to unambiguously constrain the mass of the galaxy and the anisotropy of the GC system. Red GCs show the same spatial distribution and behaviour as the starlight, whereas blue GCs have a shallower density profile, a larger velocity dispersion and a lower kurtosis, all of which suggest a different orbital distribution. We …

Dynamical Models Of Elliptical Galaxies – Ii. M87 And Its Globular Clusters, A. Angello, N. W. Evans, Aaron J. Romanowsky, J. P. Brodie

Aaron J. Romanowsky

We study the Globular Cluster (GC) system of the nearby elliptical galaxy M87 using the newly available dataset with accurate kinematics (Strader et al.2011). We find evidence for three distinct sub-populations of GCs in terms of colours, kinematics and radial profiles. We show that a decomposition into three populations (blue, intermediate and red GCs) is statistically preferred to one with two or four populations, and relate them to the stellar profile. We exploit the sub-populations to derive dynamical constraints on the mass and Dark Matter (DM) content of M87 out to ∼100 kpc. We use a class of global mass-estimators …

The Sluggs Survey: New Evidence For A Tidal Interaction Between The Early Type Galaxies Ngc 4365 And Ngc 4342, C. Blom, D. A. Forbes, C. Foster, Aaron J. Romanowsky, J. P. Brodie

Aaron J. Romanowsky

We present new imaging and spectral data for globular clusters (GCs) around NGC 4365 and NGC 4342. NGC 4342 is a compact, X-ray luminous S0 galaxy with an unusually massive central black hole. NGC 4365 is another atypical galaxy that dominates the W' group of which NGC 4342 is a member. Using imaging from the MegaCam instrument on the Canada-France-Hawaii Telescope (CFHT) we identify a stream of GCs between the two galaxies and extending beyond NGC 4342. The stream of GCs is spatially coincident with a stream/plume of stars previously identified. We find that the photometric colours of the stream …

Linked-Cluster Expansion For The Green's Function Of The Infinite-U Hubbard Model, Ehsan Khatami, Edward Perepelitsky, Marcos Rigol, Sriram B. Shastry

Ehsan Khatami

We implement a highly efficient strong-coupling expansion for the Green's function of the Hubbard model. In the limit of extreme correlations, where the onsite interaction is infinite, the evaluation of diagrams simplifies dramatically enabling us to carry out the expansion to the eighth order in powers of the hopping amplitude. We compute the finite-temperature Green's function analytically in the momentum and Matsubara frequency space as a function of the electron density. Employing Padé approximations, we study the equation of state, Kelvin thermopower, momentum distribution function, quasiparticle fraction, and quasiparticle lifetime of the system at temperatures lower than, or of the …

Magnetic Correlations And Pairing In The 1/5-Depleted Square Lattice Hubbard Model, Ehsan Khatami, Rajiv R.P. Singh, Warren E. Pickett, Richard T. Scalettar

Ehsan Khatami

We study the single-orbital Hubbard model on the 1/5-depleted square-lattice geometry, which arises in such diverse systems as the spin-gap magnetic insulator CaV4O9 and ordered-vacancy iron selenides, presenting new issues regarding the origin of both magnetic ordering and superconductivity in these materials. We find a rich phase diagram that includes a plaquette singlet phase, a dimer singlet phase, a Néel and a block-spin antiferromagnetic phase, and stripe phases. Quantum Monte Carlo simulations show that the dominant pairing correlations at half filling change character from d wave in the plaquette phase to extended s wave upon transition to the Néel phase. …

A Case Study Of A Co-Instructed Multidisciplinary Senior Capstone Project In Sustainability, Jinny Rhee, Clifton M. Oyamot, Leslie Speer, David Parent, Anuradha Basu, Larry N. Gerston

Larry N. Gerston

As societal challenges involving sustainable development increase, the need to effectively integrate this inherently multidisciplinary topic into existing curricula becomes more pressing. Multidisciplinary, team-taught, project-based instruction has shown effectiveness in teaching teamwork, communication, and life-long learning skills, and appreciation for other disciplines. Unfortunately, this instruction mode has not been widely adopted, largely due to its resource-intensiveness. Our proposed co-instruction model of multidisciplinary senior project administration was tested to see if it could effectively teach sustainability topics and duplicate the known benefits of team-taught instruction, while overcoming its resource-intensiveness. A case study of a co-instructed senior project was undertaken with students …

Keeping Education Affordable: Engaging Faculty In A Textbook Alternatives Program, Ann Agee, Mike Jerbic

Ann Agee

The average annual cost to students for textbooks is $1,754, and a recent survey found that 49% of students were likely or very likely to not buy a required textbook because of the cost. When cost is an obstacle, learning is hampered. To combat soaring costs, we launched an Affordable Learning Solutions campaign, engaging faculty in finding textbook alternatives that lower costs and improve learning. This session will explore how we recruited faculty and walk attendees through one class that uses low-cost materials and open educational resources available online.
