The Use of Faunal Remains for Identifying Shifts in Pit Structure Function in the Mesa Verde Region: a Case Study From Goodman Point

Description: The archaeofaunal remains left by the Ancestral Puebloan people of Goodman Point Unit provides a valuable, yet underutilized resource into pit structure function. This thesis explores temporal changes in pit structure use and evaluates if a final feast occurred during a kiva decommissioning. The results from zooarchaeological analyses of a pithouse and two great kivas suggest that changes in pit structures at Goodman Point mimic the regional trend toward specialization until late Pueblo III.

Using Your Imagination to Pursue Goals: Diminishing the Effects of Visceral Temptations

Description: Consumers consistently set goals for themselves. Despite good intentions, consumers often deviate from their goals. If consumers understand the benefits that arise from goal success, then why do most consumers fail to accomplish goals? Often, temptations are more appealing than achievement of goals; temptations are tangible while the benefits of a goal are difficult to grasp. An individual who uses his/her imagination to visualize goal success makes the goal more present-minded and attainable (… more

The Virtual Classroom As a Tool for the Assessment of Automatic and Controlled Processing in Autism Spectrum Disorders

Description: Assessment of executive functioning in neurodevelopmental disorders (e.g., autism) is a crucial aspect of neuropsychological evaluations. The executive functions are accomplished by the supervisory attentional system (SAS) and include such processes as inhibition, switching, and planning. Autism spectrum disorder (ASD) tends to present similarly to other neurodevelopmental disorders (e.g., ADHD). For example, ASD and ADHD may share similar etiological underpinnings in the frontostriatal system… more

Act Like a Punk, Sing Like a Feminist: A Longitudinal Content Analysis of Feminist Themes in Punk Rock Song Lyrics, 1970-2009

Description: Punk rock music has long been labeled sexist as copious media-generated accounts and reports of the genre concentrate on male artists, hyper-masculine performances, and lyrics considered to be aggressive, sexist, and misogynist. However, scholars have rarely examined punk rock music longitudinally, focusing heavily on 1980s and 1990s manifestations of the genre. Furthermore, few systematic content analyses of feminist themes in punk rock song lyrics have been conducted. The present research is … more

Atomistic Simulations of Deformation Mechanisms in Ultra-Light Weight Mg-Li Alloys

Description: Mg alloys have spurred a renewed academic and industrial interest because of their ultra-light-weight and high specific strength properties. Hexagonal close packed Mg has low deformability and a high plastic anisotropy between basal and non-basal slip systems at room temperature. Alloying with Li and other elements is believed to counter this deficiency by activating non-basal slip by reducing their nucleation stress. In this work I study how Li addition affects deformation mechanisms in Mg usi… more
