Forest roads alter hillslope hydrologic processes by intercepting, concentrating, and rerouting storm runoff. Current road drainage guidelines are based on minimizing erosion and do not take into account the impact of forest roads on hillslope hydrology. This work monitors ditch flow and rainfall for 10 road segments over the course...
Ice-penetrating radar produces detailed images of the internal ice layers in a glacier. Because the layers form from each year's snowfall, the curving of the internal layers is a record of the climate conditions that the glacier experienced as it flowed throughout the millennia. The Hiawatha Glacier lies on top...
Recent observations of tidewater glaciers find that the currently accepted model for predicting ice melt vastly underestimates observed melt rates. The release of pressurized air bubbles into the ocean from pores in the ice is one process that can amplify glacier melt. To incorporate this process into models, we need...
The process of leaving a work organization is difficult. Leaving an organization that you are part of as a volunteer is just as difficult. In fraternities, upperclassmen members tend to move out one year before they graduate. This is a problem that can create a leadership gap in the chapter...
The opportunistic pathogen Pseudomonas aeruginosa possesses two LuxR-LuxI
type quorum-sensing systems that use diffusible acyl-homoserine lactone molecules to
autoinduce and coordinate expression of multiple virulence factors. We conducted a highthroughput
screen for mutants deficient in skim-milk proteolysis—a quorum-sensing
dependent phenotype—using a nonredundant transposon-insertion library representing
most nonessential genes in P....
As a young adult, I have been able to witness first hand just how drastically social media is changing our culture and the way that we look at things. As social media continues to become more vastly used by its members who are in many different phases of life and...
Student problem behavior continues to be a primary concern in schools and, as resources decrease and greater burden is placed upon teachers, schools are pursuing better ways to mange student behavior. Researchers have continually found that when correctly implemented, Positive Behavior Supports (PBS) is an effective system for mitigating problem...
Individuals who have been traumatized have the opportunity to experience posttraumatic growth, conceptualized as positive changes that result from navigating highly challenging life circumstances (Tedeschi & Calhoun, 2004). The current model of posttraumatic growth (Calhoun, Cann, & Tedeschi, 2010) is based solely on cognitive-emotional processing yet by examining the role...
Emerging infectious diseases in wild animals threaten global biodiversity as well as domestic animal and human health. Their unprecedented increase in conjunction with anthropogenically induced range shifts of endemic pathogens exposes hosts to novel parasite combinations, lending urgency to research on disease dynamics in wildlife systems. In natural populations, hosts...
The South Pole ice core (SPC14), drilled in the field seasons of 2014/2015 and 2015/2016, is an intermediate length, 1,751-m ice core which preserves a 54,000-year record of past climate and atmospheric composition. The SPC14 ice core adds to the spatial grid of ice cores in Antarctica extending into the...
