Identification of correlations between rates of concussion and soccer positions played will lead to improved safety protocols and athlete health. Improvements can be identified by understanding the minutes played per position as fatigue is a risk factor for obtaining a concussion, in training or in game conditions by men and women soccer players. PURPOSE: To determine whether a correlation exists between minutes of soccer played, soccer position played, and the incidence of concussion among men and women collegiate soccer players.

An evaluation of characteristics of tree stumps that make them conducive for the presence of the Wandering Salamander (Aneides vagrans). I looked at stump diameter, the relative abundance of cracks on the stumps, and the amount of surface and canopy cover around the stumps to determine if wandering salamander abundance is correlated with any of those variables.

We examined how HEK293 kidney cells responded metabolically to heavy metal poisoning by cadmium chloride (CdCl2), aluminum chloride (AlCl3), and cesium chloride (CsCl) using two fluorometric assays (resazurin and MitoTracker). We then attempted to mitigate adverse effects by treating these cells with ascorbic acid (vitamin C).

You will spend more time looking at faces than any other type of object in your lifetime. Because faces are such an important social signal, humans have developed a perceptual expertise for faces. Decades of research on the mechanisms of face processing have demonstrated that although faces contain both featural and configural information humans rely more heavily on configural processing strategies when viewing faces. However, this work has been done using almost exclusively adult facial stimuli. The current study uses a well-established configural disruption known as the Thatcher Effect (TE) to investigate the use of configural processing for infant faces.

My study investigates how human disturbances affect songbird diversity and abundance in Arcata, CA. Many songbirds try to adjust their behavior in response to human populated environments; however, adjustments can have intense effects on their survival, and serious ramifications beyond urban settings (Marzluff 1997). My findings aim to better inform conservation efforts of species specific requirements and minimize areas with human disturbances as needed.

The study focuses on the effects of tidal change on marsh bird communities. A positive trend in sea level rise has been detected for the past years with approximately 20 cm increase of sea level rise per century. This can affect bird populations on wetland habitats. This study will provide data on bird species diversity at the study site and determine what bird species are more susceptible to population decrease based on habitat loss from sea level rise. The study results can call more attention on the most vulnerable bird species to prevent species extinction in marsh habitats.

An analysis into the different aspects of food insecurity we face on campus, from privatization of our food systems, administrative apathy, and consequences of food insecurity for students.

Disequilibrium reaction rim textures on olivine grains from black dacite from the 1915 eruption of Lassen Peak were measured and coupled with experimental reaction rim growth rates to estimate the duration of magma mixing that took place prior to the 1915 eruption. Reaction rims on 100 olivine grains were measured and the duration of magma mixing prior to the 1915 eruption was estimated to be between 12-17 months. The abundance of reaction rim growth varies during the duration of magma mixing and is evidence that the eruption of Lassen Peak was catalyzed by multiple injections of hot basaltic andesite into a relatively cool and mushy dacitic reservoir magma chamber prior to eruption.

The goal of this project is to establish an ethnographic archive that documents Humboldt County women's stories and experiences. This archive will contain both historical and contemporary material and be devoted to making the stories, struggles, and achievements of women in Humboldt County known. The Rebekah's Lodge was a Independent Order Of the Oddfellows, whose main goal was to serve the community around Humboldt County through their services and volunteer work.

For this project, a masters list of introduced mammals was provided. The masters list consisted of several different species of mammals who were classified by family, genus, species, and common names. Each species was accompanied by islands they were introduced too. Using the “Database of Island Invasive Species Eradication,” each animal on the list was searched for to see if they were successfully eradicated. If these animals had been eradicated, then the date and method of eradication were recorded. If these species didn’t show up on the database, then they were search for using various different search engines. If animals still remain of these islands the question becomes why?
