JTRP Technical Reports

This report is the first of a two-part, three volume final report presenting the findings of the research work that was undertaken to evaluate the behavior of Indiana highway bridges with diaphragm members welded directly to the web of the primary beams and girders. Fatigue cracks have been observed at several bridges that utilize the welded diaphragm connection. The seriousness of the cracking and the corresponding potential risk on the integrity of the bridge superstructure were assessed. Inspection and repair guidelines for bridges with the welded diaphragm connections were also developed as part of the research effort. This volume presents …

Noise Control And Speech Intelligibility Improvement Of A Toll Plaza, Luc Mongeau, Robert J. Bernhard, Jeffery P. Feist

JTRP Technical Reports

Vehicular toll roads are one component of many municipal transportation systems. Open communication windows, often used in tollbooths, facilitate essential communication and monetary transactions. However, the vehicle noise generated outside the booth is easily transmitted into the booth via the open window. Personnel working at toll collection plazas are exposed to extended, continuous traffic noise. Sustained noise levels of this nature may cause hearing loss, induce fatigue or stress, and reduce worker productivity. The annoyance and discomfort related to continuous noise exposure may create an unpleasant working condition and may affect the hospitality of the tollbooth operators and their attitude …

Performance-Related Specifications For Concrete Bridge Superstructures, Volume 1: Performance Parameters And Related Procedure For Concrete Bridge Superstructures, J. A. Ramirez, Jhon Paul Smith

JTRP Technical Reports

In Volume 1 of the final report, the identification of performance levels and parameters, and the development of acceptance criteria, have been addressed. Emphasis has been placed on the development of a methodology for a Performance Related Specification, PRS, for concrete bridge superstructures. The implementation of the methodology, presented in the form of a user-friendly computer program, is project specific. It requires the mean and standard deviation (or definition of a probability distribution) of the input parameters for the performance predictive models. This is done for both the as-designed condition and the as-built condition of the structure. The contractor is …

Performance-Related Specifications For Concrete Bridge Superstructures, Volume 4: Bond Of Epoxy-Coated Bars With Thicker Coatings, J. A. Ramirez, Michael K. Appelhans

JTRP Technical Reports

In Volume 4 of the final report, the results of an evaluation of the bond performance of epoxy-coated bars with a coating thickness up to 18 mils are presented. The experimental work on the bond performance of epoxy-coated bars with thickness up to 18 mils indicates that the current AASHTO requirements for development length of epoxy-coated bars up to #8 could be safely extended to coating thickness of up to 18 mils. Thus, no change to the bond specifications is recommended in order to implement the use of bars with diameters up to a #8 with epoxy-coating thickness up to …

Performance-Related Specifications For Concrete Bridge Superstructures, Volume 3: Nonmetallic Reinforcement, Robert J. Frosch, Christopher P. Mosley, Ahmet Koray Tureyen

JTRP Technical Reports

In Volume 3 of the final report, research work conducted to investigate the behavior of fiber reinforced polymer (FRP) reinforcement is summarized. This study focused on the behavior of FRP reinforced concrete structures with an emphasis on bond and shear. For the bond investigation, three series of beam splice tests were performed on specimens reinforced with steel, glass FRP, and aramid FRP to determine the effect of the different types of reinforcement on bond, cracking, and deflections. The test results indicate that the use of FRP reinforcement leads to lower bond strengths and, therefore, require longer development lengths. The specimen …

Scour Monitoring Of Indiana Streams, Dennis A. Lyn, Thomas J. Cooper, Yong-Kon Yi, Rahul N. Sinha, A. Ramachandra Rao

JTRP Technical Reports

The project examines the survivability and reliability of fixed-in-place continuous scour monitors for possible use in Indiana streams. The report considers primarily the experience with a sonar device at the US52 crossing of the Wabash River. Although very large flow events did not occur over the project period, the device has survived a number of smaller events, and has operated continuously without failure due to physical damage. Further, the data obtained, after appropriate processing, were examined for their credibility in terms of their correlation with a hydrologic parameter, the stage. A reasonably strong correlation was found, suggesting that the recorded …

Sign Retroreflectivity Study, Austin Lyons Bischoff, Darcy M. Bullock

JTRP Technical Reports

Signing is a big yearly cost to state DOT’s in sign maintenance and replacement costs. In 2001 the Indiana Department of Transportation (INDOT) replaced 14,930 signs at a cost of $1,067,931 and did maintenance work on 34,084 signs at a cost of $2,136,076. Recently, guidelines have been proposed by the Federal Highway Administration (FHWA) for minimum retroreflectivity of traffic signs for state, county, and city roads in the United States. The purpose of this study was to evaluate if the majority of the signs currently used by INDOT will meet the new minimum requirements proposed by the FHWA. In addition, …

Counting Device Selection And Reliability: Synthesis Study, Srinivas Peeta, Pengchang Zhang

JTRP Technical Reports

Accuracy in traffic data detection is important for transportation operations and planning. Currently, inductive loop detectors are the most commonly used traffic counting devices in the field. New technologies are being developed to meet growing data counting and traffic surveillance needs. They include passive infrared, active infrared, passive magnetic, Doppler microwave, radar, passive acoustic, pulse and Doppler ultrasonic and video image processor. However, the relatively recent, but widespread, emergence of these technologies and the consequent sparseness in information on their performance characteristics preclude traffic agencies from making informed choices in the selection of traffic counting devices. This study performs a …

Physics Conference Proceedings And The Electronic Environment—An Investigation Of New Dissemination Patterns., Michael Fosmire

Libraries Research Publications

The electronic publication of articles from physics conference proceedings on the arXive preprint server and on dedicated conference web sites is investigated. Several subdisciplines within physics were sampled. Except for high-energy theory conferences, and to a lesser extent astrophysics, there is almost no publication of proceedings articles on the preprint server. Only one conference out of all those sampled had a web site with conference presentations on it. That web site contained audio files of the presentations and images of the overheads used and thus had much different content than the published proceedings.

Telework And Work Attitudes: The Relationship Between Telecommuting And Employee Job Satisfaction, Organizational Commitment, Perceived Organizational Support, And Perceived Co-Worker Support, Erica Israelson Desrosiers

Open Access Dissertations

The present study investigates the relationship between employee telework and work attitudes, including job satisfaction, organizational commitment, perceived organizational support, and perceived co-worker support. A web-based questionnaire was distributed to employees at five organizations. Surveys were completed by 1,350 employees. A positive relationship was predicted between telework and overall job satisfaction, as mediated by perceived autonomy. Further, moderating effects of job level were predicted for the above relationships. A negative relationship was predicted between telework and perceived co-worker support, moderated by task interdependence. It was also predicted that teleworkers would report higher levels of affective commitment, and that this relationship …

Ezra Pound's Comparative Poetics, Naikan Tao

CLCWeb: Comparative Literature and Culture

In his paper, "Ezra Pound's Comparative Poetics," Naikan Tao concentrates on Pound's theories regarding comparison and examines the significance of his comparative studies to the formulation of his poetics, an aspect that has not been sufficiently investigated. On the basis of Pound's work, Tao observes that the conception of comparison Pound shaped through his comparative studies is the internal principle that governs the presentation of details and particulars, the method Pound advocated as a reader-oriented approach to truth and as an efficient, self-reliant means to avoid others' generalization and discursive presentation. Pound's view of comparison as an epistemological norm -- …

Hoosier Farmland Wildlife Notes: Windbreaks For Farms And Wildlife, Brian J. Macgowan, Brian K. Miller

Historical Documents of the Purdue Cooperative Extension Service Archive

A home or farmstead windbreak is a strip of vegetation, generally consisting of multiple rows of trees and/or shrubs that shelters a residence and related structures from the negative effects of wind. While windbreaks can provide excellent food and cover for a variety of wildlife species, their primary function is to reduce wind velocity on the leeward side of the windbreak. The degree of protection depends upon the density and height of the windbreak. However, windbreaks will typically protect an area on their leeward side of 10 times the height of the windbreak (Figure 1). Benefits of windbreaks may even …

Hoosier Farmland Wildlife Notes: Enhancing Your Farm For Northern Bobwhite Quail, Brian J. Macgowan

Historical Documents of the Purdue Cooperative Extension Service Archive

Northern bobwhite quail (Colinus virginianus) are a nonmigratory, small game bird found throughout Indiana and the eastern United States. Once very common throughout the agricultural landscape, recent population indices of this native species continue to be at or near historical lows in Indiana (Figure 1).

Loss of habitat is most likely responsible for the declines in bobwhite quail over the past half century. A shift in agricultural practices during this time is the primary cause. When quail populations in Indiana and the Midwest were much higher in the 1950s, farming practices were different than today. Farms were generally divided into …

Western Culture And The Ambiguous Legacies Of The Pig, Benton Jay Komins

CLCWeb: Comparative Literature and Culture

In his paper, "Western Culture and the Ambiguous Legacies of the Pig," Benton Jay Komins provides a cultural lineage of the pig by the example and reading of Piggies by the Beatles. Komins observes that Piggies enacts the possibilities of the ubiquitous pig in Western culture by juxtaposing swinish antics with interpretations of limitation and heartbreak thereby forcing listeners to blur the distinctions between struggle, unrequited love, and boorishness. Komins continues his discussion by locating this juxtaposition within the Western pantheon of real, metaphorical, and imaginary animals, where the pig is noted to have obsessively endured. Komins argues that through …

Aimé Césaire And Gestures Toward The Universal, Gary Leising

CLCWeb: Comparative Literature and Culture

In his paper, "Aimé Césaire and Gestures toward the Universal," Gary Leising argues that Césaire's Notebook of a Return to the Native Land presents a speaker struggling with his own identity, torn between a double consciousness of his black African heritage and his French-European education. This dichotomy appears in the poem in terms of his perceptions of his ancestry as well as in symbols of the masculine and feminine in the surrounding landscape. For the speaker, the African appears as the "real" around him, while the European is an "absent presence," and he confronts the two at the poem's climax, …

Journal of Human Performance in Extreme Environments

The purpose of this study is to identify the motivational patterns of one group of risk recreators (mountain climbers) and determine if these patterns changed as a function of experience in the activity. In this study, the sample consisted of high-altitude mountaineers attempting to climb Mount McKinley in Denali National Park, Alaska.

(Post)Feminism, Transnationalism, The Maternal Body, And Michèle Roberts, Ayako Mizuo

CLCWeb: Comparative Literature and Culture

In her paper "(Post)Feminism, Transnationalism, the Maternal Body, and Michèle Roberts," Ayako Mizuo argues that the question and problematics of feminism have diversified over the last few decades. Diverse and competing voices have been, nonetheless, incorporated into the paradigm of an equality and difference sexual dichotomy. Further, recent discussions about feminism suggest the problematization of gender differences. Consequently, exponents of postfeminism are compelled to ask what comes next? Mizuo urges that the issue of the tangibility of the body acquires a particular relevance within this context and that thus the ultimate question is how the site of the maternal body …

Language, Vagueness, And Social Communication, Colin B. Grant

CLCWeb: Comparative Literature and Culture

In his paper, "Language, Vagueness, and Social Communication," Colin B. Grant adopts an interdisciplinary approach to an interrelated complex of language, communication, and society. Grant operates with a modified concept of vagueness as a pragmatic property and attempts to establish a link between pragmatic vagueness and contingency in communication. This communicative contingency takes the form of improbabilities (entropy). Grant observes that the challenge lies in modelling communication as porous networks which nonetheless enable society to function. In this sense, contingency in communication must not be confused with arbitrariness just as cognitive closure cannot be confused with solipsism. This line of …

Entropy In Pynchon's "Entropy" And Lefebvre's The Production Of Space, Jason Snart

CLCWeb: Comparative Literature and Culture

In his paper, "Entropy in Pynchon's 'Entropy' and Lefebvre's The Production of Space," Jason Snart examines Thomas Pynchon's short story "Entropy" for the ways in which it deals with the kinds of disorder(s) associated with entropy as a thermodynamic and informational concept. Those concepts are installed as a framework within which to consider cultural studies work like Henri Lefebfre's thought in his The Production of Space and Ludwig von Bertalanffy's general systems theory and themodynamics: disorder is rendered not as confusion, but rather as a state of potential energy and productivity and Lefebvre's and Bertalanffy's concepts serve to show how …
