Highway Lighting Test Bed On Indot Facility (Off-Roadway), Xiaoqiang Hu, Jieyi Bao, Yi Jiang, Shuo Li

JTRP Technical Reports

According to the National Highway Traffic Safety Administration (NHTSA), during 2016 there were 7,277,000 vehicle crashes nationally. Among them, approximately 70% happened during the daytime and around 30% of crashes occurred during the nighttime. There were 11,375 nighttime fatal crashes that account for about 48% of total fatal crashes (23,714). Given the fact that only 25%–33% of the vehicle miles traveled (VMT) occur at night, the above statistics indicate that the nighttime crash fatality rate is much higher and nighttime crashes are usually more severe compared to daytime crashes. Providing lighting on roadways is one of the proven safety countermeasures …

Long-Term Project And Network-Level Ndt Implementation Plan For Indiana, Yunhui Jia, Christopher S. Williams, Prince Baah, Mark D. Bowman

JTRP Technical Reports

Bridge deck condition assessments in Indiana are primarily reliant on visual inspection. The condition of bridge decks, however, is highly dependent on deterioration under the surface, which includes the corrosion of steel reinforcement and concrete delamination. The implementation of reliable nondestructive testing (NDT) methods can provide information about such internal deterioration, but considering the multiple NDT methods currently available, guidance is needed to find the best approach for assessing bridge decks in the state’s bridge inventory. A research program was conducted to examine various NDT methods with the objective of recommending an effective NDT strategy for network-level and project-level bridge …

Developing An Air Pollutant Emissions Database For Global Economic Analysis, Maksym Chepeliev

Department of Agricultural Economics Faculty Publications

According to the Global Burden of Disease study (Cohen et al., 2017), in 2015 ambient air pollutant emissions caused 4.2 million deaths and a loss of 103.1 million disability-adjusted life-years, making it the fifth-ranked global risk factor. In terms of the welfare costs of mortality and illnesses associated with outdoor air pollutant emissions, global estimates for 2015 range between $2.7-3.2 trillion (Coady et al., 2015; OECD, 2016). Still, while greenhouse gas emissions are usually well represented in many global economic databases and models, air pollutant emission accounts in most cases are not included. In particular, this is the case for …

Silva, Eliseo Zeballos Zeballos, Jonathan Bauchet, Nelly Ramírez Calderón, Glenn Roberto Arce Larrea

Department of Agricultural Economics Faculty Publications

Large-scale water transfer projects (LWTPs) transfer water to urban and agricultural areas. The Majes-Siguas canal, established in 1983, is an LWTP that created a thriving agricultural area through irrigating the Majes district in the Atacama Desert of Peru. Like other LWTP receiving basins, the project has attracted an influx of migrants who work on the farms. At the same time, the Majes LWTP is the district’s only source of water and has an aging infrastructure which presents significant risks. While many studies critically analyze the consequences of LWTPs in water supply basins, few evaluate the resilience of communities living in …

Identities Development Of Adult Chinese Heritage Language Learners From Southeast Asian American Families, Feng Liang

Journal of Southeast Asian American Education and Advancement

Although linguistic and cultural varieties exist among Chinese Heritage Language Learners (CHLLs), little attention has been given to how adult CHLLs with non-Mandarin backgrounds attempt to negotiate their identities when they learned Chinese. Grounded in He’s (2008, 2016) theory of Chinese heritage language (CHL) development, this study explored the construction of identities of Chinese adults with non-Mandarin backgrounds in the process of Chinese heritage language learning. Three adult CHLLs in the United States participated in a multiple case study that lasted for six months. Data collection included interviews, journals, observations, and informal communications. Findings suggest that CHLLs of non-Mandarin backgrounds …

Praising Papers, Clarifying Concerns: How Writers Respond To Praise In Writing Center Tutorials, Mike Haen

The Writing Center Journal

In face-to-face writing center tutorials, tutor praise is an action that builds rapport and motivates writers (Mackiewicz & Thompson, 2013). Drawing on and extending prior interactional analyses of praise, this article examines writers’ responses to text-based praise across 10 tutorials, with a particular focus on interactional segments in which writers reformulate their previously mentioned concerns in response to tutor praise. Unlike more common responses that signal acceptance of the praise, such as appreciation, overt acceptance, and alignment, this responding action reflects some momentary misunderstanding between tutor and writer in the tutorial interaction. Despite this, these segments also show writers taking …

Faith, Secularism, And The Need For Interfaith Dialogue In Writing Center Work, Anna Sicari, Liliana M. Naydan, Andrea Rosso Efthymiou

The Writing Center Journal

This article argues that religious and secularist identities complement and intersect in political ways with race, class, gender, sexuality, and nationality and that they inform writing center practice because belief exists along a spectrum that involves all writing center inhabitants and affects all writing-centered conversations. We suggest that this spectrum of faith is evocative of the spectrums that theorists of race, gender, and sexuality in particular have discussed, yet often faith has been overlooked in discussions of identity in writing center work (Denny, 2010). We propose that theories of race, gender, sexuality and other identities that have served as springboards …

Review: Advocating, Building, And Collaborating: A Resource Toolkit To Sustain Secondary School Writing Centers Edited By Renee Brown And Stacey Waldrup, Jenny Goransson

The Writing Center Journal

The past decade has shown enormous growth in the number of SSWCs and a need for increased scholarship and research from this group. Inspired by the work of previous secondary school writing center director (SSWCD) authors, the content offered in the Advocating, Building, and Collaborating toolkit is rooted in directors’ real experiences in K–12 schools, rather than in the post-secondary context we find in most writing center scholarship.

Agents Of Change: African American Contributions To Writing Centers, Sue Mendelsohn, Clarissa Walker

The Writing Center Journal

African Americans and their contributions to our field’s first pedagogical models and operational structures are absent from writing center histories. This archival research invokes their presence by recounting the stories of five African American innovators—Bess Bolden “B. B.” Walcott, Coragreene Johnstone, Anne Cooke, Hugh Gloster, and Percival Bertrand “Bert” Phillips—spanning four decades at three historically Black colleges and universities (HBCUs). Their stories invite an expansive understanding of writing center work, moving beyond a focus on traditional tutoring and strictly alphabetic literacies and into “strategic literacies”—the survival skills needed to stand up for oneself and one’s community in the face of …

Unicorn Status, Queer Activism, And Bullied Laboring: Lgbtq Writing Center Directors Reflect On Invisible Work, Travis Webster

The Writing Center Journal

This article showcases interviews with lesbian, gay, bisexual, transgender, and queer (LGBTQ) writing center directors about their administrative work. In it, findings reveal that participant work distinctly departs from recent empirical writing center research about labor (Geller & Denny, 2013; Caswell, Grutsch McKinney, & Jackson, 2016), particularly in ways that practitioners’ invisible administrative work is informed and complicated by their LGBTQ identities. Across 20 interviews, participants communicated that their work extends to making queer activist space through their writing centers; to supporting tutors, students, and colleagues of all orientations with issues central to queer communities and mental health; and to …

Building Networks Of Enterprise: Sustained Learning In The Writing Center, Steve Sherwood

The Writing Center Journal

This essay examines the learning processes of writing center professionals through the lens of “networks of enterprise” (Wallace & Gruber, 1989), which reflects on the dynamic processes through which creative people, like writing center professionals (WCPs), bring together the diverse and complex tasks undertaken in their everyday work into a cohesive and satisfying career. While there is substantial turnover in the profession, some WCPs stay in writing center positions for decades. Drawing on information gathered through surveys and interviews with ten long-term WCPs (with an average of 28 years of experience), as well as reflecting on his own career, the …
