Fortification Renaissance: the Roman Origins of the Trace Italienne

Fortification Renaissance: the Roman Origins of the Trace Italienne

Date: May 2013
Creator: Vigus, Robert T.
Description: The Military Revolution thesis posited by Michael Roberts and expanded upon by Geoffrey Parker places the trace italienne style of fortification of the early modern period as something that is a novel creation, borne out of the minds of Renaissance geniuses. Research shows, however, that the key component of the trace italienne, the angled bastion, has its roots in Greek and Roman writing, and in extant constructions by Roman and Byzantine engineers. The angled bastion of the trace italienne was yet another aspect of the resurgent Greek and Roman culture characteristic of the Renaissance along with the traditions of medicine, mathematics, and science. The writings of the ancients were bolstered by physical examples located in important trading and pilgrimage routes. Furthermore, the geometric layout of the trace italienne stems from Ottoman fortifications that preceded it by at least two hundred years. The Renaissance geniuses combined ancient bastion designs with eastern geometry to match a burgeoning threat in the rising power of the siege cannon.

Online Lecture As an Alternative Method of Instruction in College Classrooms: Measuring the Effects of Alternating In-class with Online Lectures in Two Sections of an Undergraduate Introduction to Behavior Analysis Course

Online Lecture As an Alternative Method of Instruction in College Classrooms: Measuring the Effects of Alternating In-class with Online Lectures in Two Sections of an Undergraduate Introduction to Behavior Analysis Course

Date: May 2013
Creator: Treacher, Kay G.
Description: Online instruction is becoming increasingly common at universities; however, there is little single subject research concerning the effectiveness of the online lecture format. We investigated whether online lecture could replace in-class lecture in two sections of an undergraduate Introduction to Behavior Analysis course without detrimentally affecting student learning. Using an adapted alternating treatments design, online and in-class lecture formats were counterbalanced across the two course sections. Experimenters collected data on lecture attendance/access, percent correct on the weekly quiz, and student report on lecture format preference. The data show that, within the context of this class, students performed equally in the weekly quiz regardless of lecture format; further, that this is consistent when looking at individual student data and mean data. However, although students stated a preference for online lecture in the questionnaire, a greater percentage of students attended in-class lecture than accessed online lecture.

Utilizing Traditional Environmental Knowledge in Industrialized Nations to Assist in Disaster Evacuations

Date: May 2013
Creator: Lea, Brandi M.
Description: Using traditional ecological knowledge (TEK), which is typically reserved for understanding how indigenous societies function successfully, and applying this to developed countries' ideas of disaster planning and response, emergency planners, public officials, and lay-persons can gain an understanding of their environment. Stories, history, education, and The waterborne evacuation of Lower Manhattan on September 11, 2001 provides a backdrop with which to test the tenets of TEK in a developed nation setting. This dissertation has found that TEK was effective when used by a developed nation and should be integrated into the current disaster system in the US.

Graduate Students' Collaborative Information Seeking in a Group-based Learning Setting

Graduate Students' Collaborative Information Seeking in a Group-based Learning Setting

Date: May 2013
Creator: Lee, Jisu
Description: Working with others within an organization can have a variety of positive effects, and the benefits of collaboration have been discussed in various disciplines. In information science, interest in collaborative information seeking, including collaborative information seeking by students in an online learning environment is expanding. This study was aimed at understanding graduate students' collaborative information seeking behaviors through the process of a group project, including factors that affected students' perceptions of collaborative work and their difficulties during the collaborative process. The research was based on Yue and He's model, which describes information users' collaborative communication and information behaviors, and Kuhlthau's model, which describes users' individual information seeking behaviors. The participants were 43 students enrolled in a master's level course delivered primarily online. The students were required to work together in groups to complete a research project. Data were collected through a background survey, behavior survey, and online communication texts and analyzed using descriptive statistics, statistical tests, and content analyses. The results showed significant changes in collaborative and information seeking behaviors and perceptions across three stages of the project during the semester. Theoretical, practical, and methodological implications for future research are discussed.

A New Approach for Transition Metal Free Magnetic Sic: Defect Induced Magnetism After Self-ion Implantation

A New Approach for Transition Metal Free Magnetic Sic: Defect Induced Magnetism After Self-ion Implantation

Date: May 2013
Creator: Kummari, Venkata Chandra Sekhar
Description: SiC has become an attractive wide bandgap semiconductor due to its unique physical and electronic properties and is widely used in high temperature, high frequency, high power and radiation resistant applications. SiC has been used as an alternative to Si in harsh environments such as in the oil industry, nuclear power systems, aeronautical, and space applications. SiC is also known for its polytypism and among them 3C-SiC, 4H-SiC and 6H-SiC are the most common polytypes used for research purposes. Among these polytypes 4H-SiC is gaining importance due to its easy commercial availability with a large bandgap of 3.26 eV at room temperature. Controlled creation of defects in materials is an approach to modify the electronic properties in a way that new functionality may result. SiC is a promising candidate for defect-induced magnetism on which spintronic devices could be developed. The defects considered are of room temperature stable vacancy types, eliminating the need for magnetic impurities, which easily diffuse at room temperature. Impurity free vacancy type defects can be created by implanting the host atoms of silicon or carbon. The implantation fluence determines the defect density, which is a critical parameter for defect induced magnetism. Therefore, we have studied the influence ...

A Descriptive Analysis of the Use and Effect of a Self-management Project in an Undergraduate Course in Behavior Analysis

A Descriptive Analysis of the Use and Effect of a Self-management Project in an Undergraduate Course in Behavior Analysis

Date: May 2013
Creator: Lamancusa, Michelle
Description: Undergraduate male and female students enrolled in an introductory behavior analysis course with minimal instruction on self-management were given modified exploratory logs to use in a self-management project. Students self-monitored behavior via the log, constructed their own interventions, and reported changes in behavior and extent of success in a write up at course end. Changes in self-reported descriptions in the logs as well as the written results of a pre and post survey of emotional responses were counted. Successful self-management project interventions were reported by most students. Correspondence between planned and actual events increased. Negative reinforcement procedures characterized most students' intervention. Correspondence between events at pre and post and actual log reports was highest at post.

The Use of a Real Life Simulated Problem Based Learning Activity in a Corporate Environment

The Use of a Real Life Simulated Problem Based Learning Activity in a Corporate Environment

Date: May 2013
Creator: Laurent, Mark A.
Description: This narrative study examines using a real life simulated problem base learning activity during education of clinical staff, which is expected to design and develop clinically correct electronic charting systems. Expertise in healthcare does not readily transcend to the realm of manipulating software to collect patient data that is pertinent to the care of patients. To gain the expertise, troubleshooting abilities and knowledge required to maintain their clinical system, each participant in this study has gone through the RLSPBL activity. Education in the corporate world must be effective and efficient while providing a good return on the educational investment. Corporate education must use material contextually similar to a workplace, and the techniques for education must provide both near and far transfer of the material. Ten individuals (eight clinical, two non-clinical) who work across the United States were interviewed; their reflections on their career as a clinical interface designer are told here. The participants varied in their age, educational background, and current work responsibility and computer experience. Their insights revealed four major themes which summarize their stories: problem-based learning, collaboration, hands-on activities and the use of a real-life simulated problem-based learning activity.The clinical environment requires patient safety as a paramount parameter ...

Homeless Predictors in the Older Adult Population

Homeless Predictors in the Older Adult Population

Date: May 2013
Creator: Lewallen, Jina P.
Description: This secondary research study uses data from two convenience samples of homeless persons in Central Arkansas collected during 2004 and 2011 Point in Time Counts. The prevalence of predictors of homelessness are compared across years, and also compared by age (<50 and > 50) controlling for year of survey. The number of older adults increased significantly between 2004 and 2011 surveys, and reporting serious mental illness and veteran status significantly decreased from 2004 to 2011. Age differences were noted in 2004 with older adults more likely to report serious mental illness in comparison to younger adults. Older adults were also more likely to report veteran status in comparison to younger adults during both the 2004 and 2011 surveys. The predictors of homelessness -- including serious health problems, substance abuse, race, age, and developmental disabilities-- remained fairly consistent from 2004 to 2011 and across "age groups". In addition to Point in Time data, qualitative surveys and interviews of providers were performed for their observations of the older homeless population. Providers indicated their belief that the older homeless population is increasing. Providers suggested possible challenges and reasons for the increase among older adults who are homeless. In central Arkansas, service providers feel ...

A Survey of Four Original Works for Clarinet and Guitar and Their Effect on Compositional Output for the Repertoire

A Survey of Four Original Works for Clarinet and Guitar and Their Effect on Compositional Output for the Repertoire

Date: May 2013
Creator: Lignitz, Kellie
Description: In the last three decades there has been a surge in original compositions for clarinet and guitar resulting in the repertoire virtually doubling in size. However, documentation and research of original works in published sources remains limited and is quickly becoming outdated. This document reviews the current resources and reviews the newer published materials. Early chamber music works for guitar and clarinet typically required the guitar to supply harmonic support to the clarinet's upper voice, which carried the themes. An examination of the earliest works, which date from the early nineteenth century, suggests, in other words, that the two parts were not treated equally, in contrast to modern-day chamber music, in which melodic elements are proportionally balanced between the two instruments. A critical survey and comparison of four significant works from the repertoire reveals a development toward motivic balance, a progression towards melodic equality that continued in subsequent compositions. The four works surveyed are: Heinrich Neumann's Serenata Svizzera Op.29, Ferdinand Rebay's Sonata for Clarinet and Guitar No.2 in A minor, Libby Larsen's Blue Third Piece, and Gernot Wolfgang's Four Miniatures. An extensive compilation of over 300 original published and unpublished works for clarinet and guitar, bass clarinet and guitar, and ...
