Performance Of Warranted Asphalt Pavements: Smoothness And Performance Of Indiana Warranted Asphalt Pavements, Leila Sadeghi, Rebecca S. Mcdaniel, John E. Haddock

JTRP Technical Reports

In the early 1990s the Indiana Department of Transportation (INDOT) developed a five-year warranty specification for asphalt pavements with the first project being built in 1996. In 2004, results indicated that the asphalt pavements built with the warranty specification had improved performance over the conventional asphalt pavements.

Nineteen years have passed since the original asphalt pavement warranty project was placed in Indiana. It has been eleven years since the performance of the warranted asphalt pavements has been analyzed to determine the effectiveness of warranties. Therefore, it is prudent to reexamine the potential benefits of asphalt pavement warranties. Hence, the ultimate …

In Indiana, distracted driving and unexpected queues have led to an increase in the amount of back-of-queue crashes, particularly on approach to work zones. This report presents new strategies for the assessment of both transportation safety and traffic operations using crowd-sourced probe vehicle data and a speed laser vehicle re-identification scheme. This report concludes by recommending strategies for the placement of variable speed limits (VSL) adjacent to work zones and suggestions for future research.

Development Of A Cost-Effective Concrete Bridge Deck Preservation Program: Volume 1—Development And Implementation Of The Experimental Program, Robert J. Frosch, Michael E. Kreger, Emily A. Byl, John P. Lyrenmann, Andrew S. Pollastrini

JTRP Technical Reports

The deterioration of bridge decks has been identified as a major problem in Indiana. The primary cause of this deterioration is salt water ingress from the application of deicing salts during the winter. Deicing chemicals placed on the road mix with water and enter the deck through cracks and the pore structure of the concrete. This results in corrosion of the reinforcing steel and scaling of the surface, which leads to a shortened bridge deck life and costly deck replacement. The objective of this study is to investigate potentially effective and economic bridge deck preservation methods to significantly extend the …

JTRP Technical Reports

The ability to accurately measure and cost-effectively collect traffic data at road intersections is needed to improve their safety and operations. This study investigates the feasibility of using laser ranging technology (LiDAR) for this purpose. The proposed technology does not experience some of the problems of the current video-based technology but less expensive low-end sensors have limited density of points where measurements are collected that may bring new challenges. A novel LiDAR-based portable traffic scanner (TScan) is introduced in this report to detect and track various types of road users (e.g., trucks, cars, pedestrians, and bicycles). The scope of this …

Duties To Organizational Clients, William H. Simon

Faculty Scholarship

Loyalty to an organizational client means fidelity to the substantive legal structure that constitutes it. Although this principle is not controversial in the abstract, it is commonly ignored in professional discourse and doctrine. This article explains the basic notion of organizational loyalty and identifies some mistaken tendencies in discourse and doctrine, especially the "Managerialist Fallacy" that leads lawyers to conflate the client organization with its senior managers. The article then applies the basic notion to some hard cases, concluding with a critical appraisal of the rationale for confidentiality with organizational clients.

Creating Shared Norms In Schools - A Theoretical Approach, Maryanne Macdonald, Eyal Gringart, Jan Gray

Research outputs 2014 to 2021

Whilst some improvements to Indigenous education outcomes have occurred in recent years, there remains considerable inequity in the educational experiences and long-term engagement of Indigenous and non-Indigenous students. One of the factors contributing to the challenging environment for Indigenous students is dissonance of social norms, as a result of ethnic and socioeconomic differences between teacher and student. Many hegemonic culture teachers are unaware of Standpoint Theory and the way in which normative beliefs impact on classroom interactions and student outcomes at the cultural interface. This paper draws on the Theory of Planned Behaviour (TBP) to illustrate ways in which schools …

Research outputs 2014 to 2021

Introduction:Background to metabolomics:

Metabolomics is the comprehensive study of the metabolome, the repertoire of biochemicals (or small molecules) present in cells, tissues, and body fluids. The study of metabolism at the global or “-omics” level is a rapidly growing field that has the potential to have a profound impact upon medical practice. At the center of metabolomics, is the concept that a person’s metabolic state provides a close representation of that individual’s overall health status. This metabolic state reflects what has been encoded by the genome, and modified by diet, environmental factors, and the gut microbiome. The metabolic profile provides …

Re-Conceptualising Graduate Employability: The Importance Of Pre-Professional Identity, Denise Jackson

Research outputs 2014 to 2021

Despite efforts to broaden the concept of graduate employability, there remains an overarching focus on developing industry-relevant employability skills. The skills-based approach is, however, too narrow and does not fully capture the complexity of graduate work-readiness. This paper argues for the redefining of graduate employability by embracing pre-professional identity (PPI) formation. PPI relates to an understanding of and connection with the skills, qualities, conduct, culture and ideology of a student's intended profession. The ‘communities of practice’ model is drawn upon to demonstrate how PPI can be developed during university years. Here, a student makes sense of his/her intended profession through …

Permanent Slides For Morphological Studies Of Small Crustaceans: Serban's Method And Its Variation Applied On Bathynellacea (Malacostraca), Giulia Perina, Ana I. Camacho

Research outputs 2014 to 2021

Morphological studies of small invertebrates often involve the preparation of slides to observe minute body parts under a compound microscope. Preparation should facilitate observation, through traditional optical microscopy, of small surface structures on different planes, like pores, spines and setae. Various methods and techniques, using different mounting media that specialists have adopted to observe and preserve small crustaceans, have their advantages and disadvantages.Within the order Bathynellacea, specimens in the family Bathynellidae are particularly challenging due to their small size (0.5 to 2.25 mm body length) and very delicate exoskeleton, which tends to be completely digested when using common clearing mounting …

The Influence Of The Sex Of And Prior Relationship Between The Perpetrator And Victim On Perceptions Of Stalking: A Qualitative Analysis, Jeff Bath, Adrian J. Scott

Research outputs 2014 to 2021

The sex of and prior relationship between the perpetrator and victim have been shown to influence perceptions of stalking. To explore the ways in which shared assumptions around these factors interact to shape perceptions of stalking, this study analyses the deliberations of mock juries as they attempt to reach a unanimous verdict on a hypothetical stalking case summary. Twelve mock juries comprising between five and six ‘jurors’ (n = 64) were presented with one of three versions of a case summary (stranger, acquaintance, and ex-partner) describing a man stalking a woman or a woman stalking a man. Thematic analysis shows …

As a result of climate change warmer temperatures are projected through the 21st century and are already increasing above modelled predictions. Apart from increases in the mean, warm/hot temperature extremes are expected to become more prevalent in the future, along with an increase in the frequency of droughts. It is crucial to better understand the response of terrestrial ecosystems to such temperature extremes for predicting land-surface feedbacks in a changing climate. While land-surface feedbacks in drought conditions and during heat waves have been reported from Europe and the US, direct observations of the impact of such extremes on the carbon …

Research outputs 2014 to 2021

There are considerable differences in the structure, content, and delivery of tertiary journalism degrees in Australia as identified in a 2014 Office for Learning and Teaching (OLT) Innovation and Development Project report on graduate qualities and journalism curriculum renewal. To address this situation, the author argues for journalism capstone units, designed by both journalism educators and news editors, to include a series of agreed criteria and standards to guide journalism educators, and for journalism students to demonstrate not only a broad knowledge base together with research and communication skills but also entrepreneurial skills to help them adapt to new media …

Towards A Participatory Netnography: Collaborating With Children In Virtual Worlds Research, Ashley Donkin, Donell Holloway, Lelia Green

Research outputs 2014 to 2021

The new sociology of childhood has encouraged social researchers to incorporate children in as much of the research process as possible. However, whilst some success has been achieved within traditional ethnographic studies, netnography has been slow to make this a reality. This article discusses the previous online research into children’s virtual worlds, which has rarely incorporated young children into the data collection or research analysis processes. The opportunity for researchers to use participatory approaches to collaborating with their child participants and collecting online data is limited due to ethical constraints. The ethical challenges of conducting netnography are compounded by a …

The Possibilities Of A Line: Marking The Glissando In Music, Cat Hope, Michael Terren

Research outputs 2014 to 2021

The glissando as it is deployed in Western art music notation carries with it a number of challenges to the hegemony of traditional harmony, rhythm, and notation. The glissando embodies the smooth line, unlike the striated pitch-time space of traditional Western music, which aligns the glissando to many philosophical concepts, as well as mathematical, scientific, and architectural disciplines. Select works by Iannis Xenakis, James Tenney and Giacinto Scelsi are discussed for their development of glissandi as integral formal components, especially around the glissando’s tendency to encourage stasis. Compositional attempts to combine the nature of glissandi with drone in the author’s …

Stick Or Switch: A Selection Heuristic Predicts When People Take The Perspective Of Others Or Communicate Egocentrically, Shane Rogers, Nicholas Fay

Research outputs 2014 to 2021

This paper examines a cognitive mechanism that drives perspective-taking and egocentrism in interpersonal communication. Using a conceptual referential communication task, in which participants describe a range of abstract geometric shapes, Experiment 1 shows that perspective-taking and egocentric communication are frequent communication strategies. Experiment 2 tests a selection heuristic account of perspective-taking and egocentric communication. It uses participants' shape description ratings to predict their communication strategy. Participants' communication strategy was predicted by how informative they perceived the different shape descriptions to be. When participants' personal shape description was perceived to be more informative than their addressee's shape description, there was a …
