Existing studies of hospital readmissions typically focus on specific diagnoses, age groups, discharge dispositions, payer classes, or hospitals, and often use small samples. It is not clear how predictive models generated from such studies generalize across diseases, hospitals, or time periods. In this study, a logistic regression model of readmission risk within 30 days based on hospital administrative data was constructed and validated across hospitals and time periods. The hospitals included both general and specialty hospitals such as long-term care, women’s, and children’s hospitals. The administrative data included information on patient’s demographics, diagnoses, procedures, and discharge disposition. Derivation and validation …

Journal of Human Performance in Extreme Environments
We used a field excursion to the West Clearwater Lake Impact structure as an opportunity to test factors that contribute to the decisions a remote field team (for example, astronauts conducting extravehicular activities (EVA) on planetary surfaces) makes while collecting samples for return to Earth. We found that detailed background on the analytical purpose of the samples, provided to the field team, enables them to identify and collect samples that meet specific analytical objectives. However, such samples are not always identifiable during field reconnaissance activities, and may only be recognized after outcrop characterization and interpretation by crew and/or science team …

Identity, Critical Agency, And Engineering Majors: An Affective Model For Predicting Engineering As A Career Choice., Allison Godwin, Geoff Potvin, Zahra Hazari, Robynne Lock
School of Engineering Education Faculty Publications
Prior to college, many students do not have experience with engineering, but some ultimately choose an engineering career. Additionally, women choose engineering at lower rates than men, which results in women’s underrepresentation. The framework of critical engineering agency (CEA) is utilized to understand student attitudes and beliefs for choosing engineering. We investigate the relationships among students’ math and physics identities in high school that predict choice of engineering careers; how students’ beliefs about science and technology predict a choice of engineering careers; whether these beliefs are different by gender; and how well CEA explains students’ engineering choice. The data were …

Systematic Literature Review Of The Use Of Rich Media In Stem And Related Education, Tony A. Lowe
School of Engineering Education Graduate Student Series
The use of video in pedagogy is well established in the modern classroom with researched understanding of its benefits. Prior literature reviews provide a foundation for the impacts within a wide scope of environments and subjects. These reviews primarily have looked at students and faculty attitudes, learning outcomes, and the impact on attendance. The impact has been spread over general subject matter with little focus on the often challenging topics of STEM education. Many topics in STEM education are highly procedural, such as mathematical proofs or writing code or conducting experiments. Understanding the costs and benefits of using video to …
Estimating The Water Quality Condition Of River And Lake Water In The Midwestern United States From Its Spectral Characteristics, Jing Tan
Open Access Dissertations
This study focuses on developing/calibrating remote sensing algorithms for water quality retrieval in Midwestern rivers and lakes. In the first part of this study, the spectral measurements collected using a hand-held spectrometer as well as water quality observations for the Wabash River and its tributary the Tippecanoe River in Indiana were used to develop empirical models for the retrieval of chlorophyll (chl) and total suspended solids (TSS). A method for removing sky and sun glint from field spectra for turbid inland waters was developed and tested. Empirical models were then developed using a subset of the field measurements with the …

Borges's Postmodern Landscape, Mario Vrbančić
Borges's Postmodern Landscape, Mario Vrbančić
CLCWeb: Comparative Literature and Culture
In his article "Borges's Postmodern Landscape" Mario Vrbančić examines specific constructs of space -- among them heterotopia (Michel Foucault) and hyperreality (Jean Baudrillard) -- and applies them to narration and narrative strategies in Jorge Luis Borges's texts. Vrbančić posits that postmodern mapping undermines our known familiar geography and that authors like Borges who experimented with different spaces and connections in their texts, represent postmodernism avant la lettre.
Generalized Techniques For Using System Execution Traces To Support Software Performance Analysis, Thelge Manjula Peiris
Generalized Techniques For Using System Execution Traces To Support Software Performance Analysis, Thelge Manjula Peiris
Open Access Dissertations
This dissertation proposes generalized techniques to support software performance analysis using system execution traces in the absence of software development artifacts such as source code. The proposed techniques do not require modifications to the source code, or to the software binaries, for the purpose of software analysis (non-intrusive). The proposed techniques are also not tightly coupled to the architecture specific details of the system being analyzed. This dissertation extends the current techniques of using system execution traces to evaluate software performance properties, such as response times, service times. The dissertation also proposes a novel technique to auto-construct a dataflow model …

The Impact Of Crystal Morphology On The Thermal Responses Of Ultrasonically-Excited Energetic Materials, J. K. Miller, J. O. Mares, I. E. Gunduz, Steven F. Son, Jeff Rhoads
Purdue Energetics Research Center Articles
The ability to detect explosive materials may be significantly enhanced with local increases in vapor pressure caused by an elevation of the materials'temperature. Recently, ultrasonic excitation has been shown to generate heat within plastic-bonded energetic materials. To investigate the impact of crystal morphology on this heating, samples of elastic binder are implanted with single ammonium perchlorate crystals of two distinct shape groups. Contact piezoelectric transducers are then used to excite the samples at ultrasonicfrequencies. The thermal responses of the crystals are recorded using infrared thermography, and the rate of heating is estimated. Surface temperature increases up to 15 °C …

Evaluation Of Alternative Intersections And Interchanges: Volume I—Roundabout Capacity And Rollover Analysis For Heavy Vehicles, Andrew P. Tarko, Mario Romero, Thomas Hall, Shaikh Ahmad Matin, Cristhian Lizarazo
JTRP Technical Reports
There is a recent trend of building roundabouts on high-speed roads, often with the considerable presence of heavy vehicles. With the increased presence of trucks on roundabouts, the issue of overturning has become a concern. Although some geometric, vehicle, and loading factors have been connected to rollover, the safety performance of roundabouts built on high-speed roads is not well understood due to their relative novelty. In addition, other concerns related to geometry, driver behavior, and environmental considerations may exist at roundabouts. This study examined roundabout circulatory superelevation, aggressive driver behavior, roundabout readability, and nighttime conditions in the context of heavy …

Time Distortion In Bierce's "One Of The Missing" And Uroshevic's "Ракописот Од Китаб-Ан" ("The Manuscript From Kitab-An"), Kalina Maleska
CLCWeb: Comparative Literature and Culture
In her article "Time Distortion in Bierce's 'One of the Missing' and Uroshevic's 'Ракописот од Китаб-Ан' ('The Manuscript from Kitab-An')" Kalina Maleska examines the relationship between literature and astronomy in the context of time. The two stories share several common elements: they explore the possible manipulations of time in unexpected and extraordinary ways and come close to certain scientific explorations of time. For "One of the Missing," Albert Einstein's theory of relativity provides an interesting foundation for understanding Bierce's treatment of time. For The Manuscript of Kitab-An, the speculations of time travel starting from the Einstein-Rosen concept of the black …

Changes In Teachers’ Adaptive Expertise In An Engineering Professional Development Course, Taylor Martin, Stephanie Baker Peacock, Pat Ko, Jennifer J. Rudolph
Journal of Pre-College Engineering Education Research (J-PEER)
Although the consensus seems to be that high-school-level introductory engineering courses should focus on design, this creates a problem for teacher training. Traditionally, math and science teachers are trained to teach and assess factual knowledge and closed-ended problemsolving techniques specific to a particular discipline, which is unsuited for teaching design skills for open-ended problems that may involve multiple engineering disciplines. Instead, engineering teacher training should use the more fluid framework of adaptive expertise which values the ability to apply knowledge in innovative ways as well as recall facts and solve problems using conventional techniques. In this study, we examined a …

Journal of Human Performance in Extreme Environments
Background: Prevention of heat illness is of considerable medical interest within the field of occupational work. There are many established methods of perceptual health assessment; however, many are rather unpractical and timely. The objective was to improve the practicality and timeliness of perceptual physiological monitoring; a Heat Thermal Sensation scale has been developed. The usefulness of the scale was assessed on its ability to monitor physiological variable. Materials and Methods: Ten apparently healthy individuals performed physically exerting activity while exposed to 37 °C. Sensation and physiology were measured throughout. Results: The perceptual monitoring scale demonstrated weak positive correlations with human …

Effect Of An Engineering Camp On Students’ Perceptions Of Engineering And Technology, Rebekah Hammack, Toni A. Ivey, Juliana Utley, Karen A. High
Journal of Pre-College Engineering Education Research (J-PEER)
Students’ knowledge about a profession influences their future decisions about careers. Research indicates that students tend to hold stereotypical views of engineers, which would hinder engineering as a career choice. The purpose of this study was to measure how participating in a week long engineering summer camp affected middle school students’ (N519) attitudes towards engineering and their conceptions of engineering and technology. Results indicate that participation in the programs had a positive impact on the students’ understandings of what technology is and the work engineers do. Although the results indicate a positive impact on participants, it is not clear which …

Journal of Pre-College Engineering Education Research (J-PEER)
The present study examines middle school teachers’ beliefs about seven learning outcomes related to a project that involves developing and examining the effects of a set of engineering design modules constructed for use by middle school math and science teachers. Overall, the teachers involved in the intervention appear to believe they have the instructional skills, professional development, and resources to carry out the modules. Teachers from all of the schools (both intervention and comparison schools) for the most part valued the outcomes as important. Results of the study indicate that, although teachers believe they value and can obtain most of …

Marbles: The Application Of Input-Output Concepts To Safety Management Systems, Tim Brady, Alan Stolzer, Anthony Brickhouse, Antonio Cortés, Dan Mccune, Jayathi Raghavan, David Freiwald
Journal of Aviation Technology and Engineering
The goal of this research was to apply the economic concept titled Input-Output Analysis to an aviation safety concept titled Safety Management Systems (SMS). Input-Output (IO) is based upon the interrelationships of various components of an economic system and what happens to the system when one or more of those components changes. Since SMS is, by definition, a system with definable components, the research sought to determine if the interrelationships between those components could be determined and quantified. The term ‘‘marbles’’ was used to describe the activities that led to the IO-SMS matrix. Marbles was used as a metaphor for …
