  • Voter Displeasure: The Role of Dislike For the Opposition In the 2016 U.S. Presidential Election

    Creator:
    Schiek, Andrew
    Abstract:
    One of the surprising things about the 2016 presidential election was how much each presidential candidate was disliked. In this historic election, questions about whether voters made their decisions by supporting their candidate or voting against another have arisen. Studies have been done in the past that examine which traits...

    Abstract:
    Cells in three-dimensional (3D) environments exhibit very different biochemical and biophysical phenotypes compared to the behavior of cells in two-dimensional (2D) environments. As an important biomechanical measurement, 2D traction force microscopy can not be directly extended into 3D cases. In order to quantitatively characterize the contraction field, we have developed...

  • Skill progression demonstrated by users in the Scratch animation environment

    Creator:
    Scaffidi, Christopher and Chambers, Christopher
    Abstract:
    The Scratch environment exemplifies a tool+community approach to teaching elementary programming skills, as it includes a website where users can publish, discuss, and organize animations that are programs. To explore this environment’s effectiveness for helping people to develop programming skills, we performed a quantitative analysis of 250 randomly-selected users’ data,...

    Abstract:
    This paper proposes a technique, called Smell-driven performance tuning (SDPT), which semi-automatically assists end-user programmers with fixing performance problems in visual dataflow programming languages. A within-subjects laboratory experiment showed SDPT increased end-user programmers’ success rate and decreased the time they required. Another study, based on using SDPT to analyze a...

    Abstract:
    This paper proposes a technique, called Smell-driven performance analysis (SDPA), which automatically provides situated explanations within a visual dataflow language IDE to help end-user programmers to overcome performance problems without leaving the visual dataflow paradigm. An experiment showed SDPA increased end-user programmers’ success rates at finding performance problems and decreased...

    Abstract:
    This study examines climatological influences, particularly that of snowpack, on tree growth and stable carbon isotope discrimination (Δ¹³C) from ~1980 to 2013 at two sites located in the upper reaches of the McKenzie River watershed of the Oregon Cascade Mountains. We tested the use of Δ¹³C values from latewood, corroborated...

  • Durable resistance: A key to sustainable management of pathogens and pests

    Creator:
    Mundt, Christopher C.
    Abstract:
    This review briefly addresses what has been learned about resistance durability in recent years, as well as the questions that still remain. Molecular analyses of major gene interactions have potential to contribute to both breeding for resistance and improved understanding of virulence impacts on pathogen fitness. Though the molecular basis...

    Abstract:
    BACKGROUND: Oregon produces 99% of the hazelnuts grown in the United States. The key pest threatening commercial hazelnut orchards in Oregon is Cydia latiferreana (Tortricidae), filbertworm moth (FBW). Currently, most growers control FBW with one to two applications of esfenvalerate (Asana XL), a broad spectrum pyrethroid. Pheromone mating disruption is...
