Talking In: Maori English as Index for Maori identity in Film

Allura Warden
New Zealand cinema often represented Maori people as an exotic background to a paradisaical country while Pakeha were represented as heroic protagonists helping bring progress to a backwards nation. Until recently the national film industry was almost entirely Pakeha run. Consequently, there was a dearth of Maori presence in all industry positions. However, since the Maori cultural revolution there has been progress in Maori cinematic presence which has spurred the creation of Maori-produced media. Their...

Thermal Analysis of High Altitude Ballooning Payloads

Paul Hughes
Balloon-borne telescopes have the potential to produce almost space telescope quality data, because stratospheric balloons float above 99% of the atmosphere. The stratospheric environment poses unique and unsolved issues especially in the thermal stability of the optics. To inform the design of the future ”Testbed for High-Acuity Imaging - Stable Photometry and Image-Motion Compensation Experiment” balloon borne telescope, a team formed to improve thermal models for the stratosphere, especially by including convection. To accomplish such...

Examination of Planetary Systems with Kepler Data

Claire Teclaw
In this period of study we attempted to use data from the Kepler archive to deduce information about planetary systems observed by that mission. The ultimate goal was to potentially identify features of the planets in these systems by examining ellipsoidal variations in their light curves. For this purpose we attempted to, separately, apply PyKE utilities and create new code to search the mission’s fits files. We discovered potential issues with the PyKE code regarding...

Liberation through Cooperation: How Library Publishing Can Save Scholarly Journals from Neoliberalism

Dave Ghamandi
This commentary examines political and economic aspects of open access (OA) and scholarly journal publishing. Through a discourse of critique, neoliberalism is analyzed as an ideology causing many problems in the scholarly journal publishing industry, including the serials crisis. Two major efforts in the open access movement that promote an increase in OA funded by article-processing charges (APC) —the Open Access 2020 (OA2020) and Pay It Forward (PIF) initiatives—are critiqued as neoliberal frameworks that would...

Design rules for interfacial thermal conductance: Building better bridges

Carlos A. Polanco, Rouzbeh Rastgarkafshgarkolaei, Jingjie Zhang, Nam Q. Le, Pamela Norris & Avik Ghosh
We study the thermal conductance across solid-solid interfaces as the composition of an intermediate matching layer is varied. In the absence of phonon-phonon interactions, an added layer can make the interfacial conductance increase or decrease depending on the interplay between (1) an increase in phonon transmission due to better bridging between the contacts and (2) a decrease in the number of available conduction channels that must conserve their momenta transverse to the interface. When phonon-phonon...

Phonon-mediated thermal transport at exponentially mass-graded interfaces: A computational study

Rouzbeh Rastgarkafshgarkolaei, Jinjie Zhang, Carlos A. Polanco, Nam Q. Le, Avik Ghosh & Pamela Norris
We numerically investigate thermal transport at solid-solid interfaces with graded intermediate layers whose masses vary exponentially from one side to the other. Using Non-Equilibrium Green's Function and Non-Equilibrium Molecular Dynamics simulations, we show that an exponentially mass-graded junction with a finite thickness can result in 68% of enhancement in thermal conductance larger compared to a single bridging layer (29%) and a linear mass-graded junction (64%) of similar thickness. We examine how the thermal conductance at...

Waitman Beorn
Describes how one concentration camp survivor witnessed sexual violence and documented it in his drawings during the Holocaust.

Data from: Early changes in transient adenosine during cerebral ischemia and reperfusion injury

Mallikarjunarao Ganesana & B. Jill Venton
Adenosine is an important neuromodulator in the central nervous system, and tissue adenosine levels increase during ischemic events, attenuating excitotoxic neuronal injury. Recently, our lab developed an electrochemical fast-scan cyclic voltammetry (FSCV) method that identified rapid, spontaneous changes in adenosine concentrations that last only about 3 seconds. Here, we investigated the effects of cerebral ischemia and reperfusion on the concentration and frequency of transient adenosine release in the caudate-putamen. In anesthetized rats, data were collected...

Data from: Is there a disease-free halo at species range limits? The co-distribution of anther-smut disease and its host species

Emily L. Bruns, Janis Antonovics & Michael Hood
1. While disease is widely recognized as affecting host population size, it has rarely been considered to play a role in determining host range limits. Many diseases may not be able to persist near the range limit if host population density falls below the critical threshold level for pathogen invasion. However, in vector- and sexually-transmitted diseases, pathogen transmission may be largely independent of host density and theory demonstrates that diseases with frequency-dependent transmission may persist...

Data from: The role of infectious disease in the evolution of females: evidence from anther-smut disease on a gynodioecious alpine carnation

Emily L. Bruns, Ian Miller, Michael E. Hood, Valentina Carasso & Janis Antonovics
In flowering plants, the evolution of females is widely hypothesized to be the first step in the evolutionary pathway to separate male and female sexes, or dioecy. Natural enemies have the potential to drive this evolution if they preferentially attack hermaphrodites over females. We studied sex-based differences in exposure to anther-smut (Microbotryum), a sterilizing pollinator-transmitted disease, in Dianthus pavonius, a gynodioecious perennial herb. We found that within a heavily diseased population, females consistently had lower...

The Distance to the Sagittarius Dwarf Galaxy and its Relation to M54 using Infrared Photometry of RR Lyrae Variable Stars

Arvind Gupta
The Sagittarius dwarf galaxy (Sgr) is among the most massive satellites of the Milky Way and is unique due to its extensive tails of tidally stripped stars. Models of these tails provide strong constraints on the orbital history of Sgr, which in turn lend insight into the structure of the Milky Way’s dark matter halo. Fully understanding the dynamics of Sgr, however, relies on a precise distance to the core. Yet past measurements yield a...

University of Virginia Library Discovery Layer Recommendation

Ellen Ramsey, Carla Lee, Raymond Lubinsky, Jeremy Bartczak, Todd Burks, Dave Griles, Robert Haschart, Nestor Walker, Mark Witteman & Christopher Welte
In August of 2018, the University of Virginia Library's Virgo 4 Project Team recommended Blacklight 7 for comprehensive discovery of UVA Library holdings via a sustainable technology stack. Virgo 3, built on Blacklight/Rails 3, is outdated and unable to progress further. For the Library's discovery layer, a modern architecture is needed to better interface with our users. UVA stakeholder requirements emphasize an interface to the Library's collections that meets the needs of both novice and...

Data from: Morphology of the core fibrous layer of the cetacean tail fluke

William T. Gough, Frank E. Fish, Dylan K. Wainwright & Hilary Bart-Smith
The cetacean tail fluke blades are not supported by any vertebral elements. Instead, the majority of the blades are composed of a densely packed collagenous fiber matrix known as the core layer. Fluke blades from six species of odontocete cetaceans were examined to compare the morphology and orientation of fibers at different locations along the spanwise and chordwise fluke blade axes. The general fiber morphology was consistent with a three‐dimensional structure comprised of two‐dimensional sheets...

Data from: Spatiotemporal dynamics and genome-wide association analysis of desiccation tolerance in Drosophila melanogaster

Subhash Rajpurohit, Eran Gefen, Alan O. Bergland, Dmitri A. Petrov, Allen G. Gibbs & Paul S. Schmidt
Water availability is a major environmental challenge to a variety of terrestrial organisms. In insects, desiccation tolerance varies predictably over spatial and temporal scales and is an important physiological determinant of fitness in natural populations. Here, we examine the dynamics of desiccation tolerance in North American populations of Drosophila melanogaster using: 1) natural populations sampled across latitudes and seasons; 2) experimental evolution in field mesocosms over seasonal time; 3) genome-wide associations to identify SNPs/genes associated...

Data from: Relative effects of LDL-C on ischaemic stroke & coronary disease: a Mendelian randomization study

Elsa Valdes-Marquez, Sarah Parish, Robert Clarke, Traiani Stari, Bradford B. Worrall & Jemma C. Hopewell
Objective: To examine the causal relevance of lifelong differences in LDL-C for ischaemic stroke (IS) relative to that for coronary heart disease (CHD) using a Mendelian randomization approach. Methods: We undertook a two-sample Mendelian randomization, based on summary data, to estimate the causal relevance of LDL-C for risk of IS and CHD. Information from 62 independent genetic variants with genome-wide significant effects on LDL-C levels was used to estimate the causal effects of LDL-C for...

Data from: Populations with greater flexibility in floral traits modify mating system in response to the pollinator environment

Lia Leibman, Anne Rowe, Matthew H. Koski & Laura F. Galloway
1. Mixed mating and variation in outcrossing rate among populations of the same species are common. Outcrossing can be affected by pollinator activity and floral traits that facilitate or impede autonomous self-fertilization. However, the relative contribution of pollen limitation and evolved differences in the ability to self fertilize to variation in the mating system is poorly understood and can only be disentangled using an experimental approach. 2. We placed arrays of plants from eight Campanula...

Data from: Co-occurrence among three divergent plant-castrating fungi in the same silene host species

Jessica L. Abbate, Pierre Gladieux, Michael E. Hood, Damien M. De Vienne, Janis Antonovics, Alodie Snirc & Tatiana Giraud
The competitive exclusion principle postulates that different species can only coexist in sympatry if they occupy distinct ecological niches. The goal of this study was to understand the geographical distribution of three species of Microbotryum anther-smut fungi that are distantly related but infect the same host plants, the sister species Silene vulgaris and S. uniflora, in western Europe. We used microsatellite markers to investigate pathogen distribution in relation to host specialization and ecological factors. Microbotryum...

Data from: A key floral scent component (β-trans-bergamotene) drives pollinator preferences independently of pollen rewards in seep monkeyflower

Ariela I. Haber, James W. Sims, Mark C. Mescher, Consuelo M. De Moraes & David E. Carr
1) Floral odors play an important role in attracting insect pollinators. Because pollinators visit flowers to obtain pollen and nectar rewards, they should prefer floral odor profiles associated with the highest-rewarding flowers (honest signals). In previous work, bumble bees exhibited a preference for flowers from outbred over inbred Mimulus guttatus plants. Pollen is the only floral reward in M. guttatus, and pollen viability (a reliable indicator of protein content) is reduced in inbred plants. Yet,...

Data from: Archaeogenomic evidence from the southwestern US points to a pre-Hispanic scarlet macaw breeding colony

Richard J. George, Stephen Plof, Adam S. Watson, Kari L. Schmidt, Brandon J. Culleton, Thomas K. Harper, Patricia A. Gilman, Steven A. LeBlanc, George Amato, Peter Whiteley, Logan Kistler & Douglas J. Kennett
Hundreds of scarlet macaw (Ara macao cyanoptera) skeletons have been recovered from archaeological contexts in the southwestern United States and northwestern Mexico (SW/NW). The location of these skeletons, >1,000 km outside their Neotropical endemic range, has suggested a far-reaching pre-Hispanic acquisition network. Clear evidence for scarlet macaw breeding within this network is only known from the settlement of Paquimé in NW dating between 1250 and 1450 CE. Although some scholars have speculated on the probable...

Data from: Adaptive radiation along a deeply conserved genetic line of least resistance in Anolis lizards

Joel W. McGlothlin, Megan E. Kobiela, Helen V. Wright, D. Luke Mahler, Jason J. Kolbe, Jonathan B. Losos, & Edmund D. Brodie
On microevolutionary timescales, adaptive evolution depends upon both natural selection and the underlying genetic architecture of traits under selection, which may constrain evolutionary outcomes. Whether such genetic constraints shape phenotypic diversity over macroevolutionary timescales is more controversial, however. One key prediction is that genetic constraints should bias the early stages of species divergence along “genetic lines of least resistance” defined by the genetic (co)variance matrix, G. This bias is expected to erode over time as...
