Implementing Integrated Stem Forensic And Soil Sciences Lab Activities To Promote Interest In Stem Careers, Mariah K. Stollar Awan, Caroline J. Rakowski

Indiana STEM Education Conference

We implemented forensic and soil science integrated STEM lab activities with 11 middle school youth at a 4-H day camp at Purdue University. STEM perceived knowledge increased overall for participants. However, the pre- and post-assessments did not show a statistically significant difference. More students also indicated STEM career interest after participating. Because this study was exploratory and had a small sample size, more research on these integrated STEM lab activities should be conducted with larger samples.

Quantitative, empirical approaches to establishing the structure of psychopathology hold promise to improve on traditional psychiatric classification systems. The Hierarchical Taxonomy of Psychopathology (HiTOP) is a framework that summarizes the substantial and growing body of quantitative evidence on the structure of psychopathology. To achieve its aims, HiTOP must incorporate emerging research in a systematic, ongoing fashion. In this article, we describe the historical context and grounding of the principles and procedures for revising the HiTOP framework. Informed by strengths and shortcomings of previous classification systems, the proposed revisions protocol is a formalized system focused around three pillars: (a) prioritizing systematic …

Incorporating Time-Dependent Data For Proactive Safety Management, Raul Pineda-Mendez, Qiming Guo, Noshin Ahmad, Mario A. Romero, Andrew P. Tarko

JTRP Technical Reports

This study proposed a risk-based safety management framework to supplement the current crash-based safety management system. The proposed tool considers time-dependent factors (e.g., hourly traffic, speed features, weather conditions, signal controls) to help justify operational measures for safety improvements (e.g., variable message signs, variable speed limits, warnings). These selected temporal factors subsequently were included in the developed sequential logit models; and those models, applied hour by hour, were then used to estimate the crash probability and severity level. Two typical roadway elements, rural freeway segments and signalized intersections, were also included in the analysis. The obtained crash risk profiles can …

JTRP Technical Reports

A literature review was conducted to evaluate current standards and existing research around the use of plasma arc cutting for holes (PACH) in the context of steel bridge applications. Additionally, an investigation into the state of the practice was conducted to determine if the latest technological advancements and equipment capabilities for plasma cutting could prove PACH to be an acceptable hole making process for bridge applications. Much of the existing research focuses on drilling and punching to make holes, but very limited experimental studies and data exists specifically evaluating plasma arc cutting. The most comprehensive study, including PACH, is discussed …

Discursive Practices In Recurring Asynchronous Writing Center Consultations, Olalekan T. Adepoju

The Writing Center Journal

This study explores the discursive practices the researcher utilizes during recurring asynchronous writing consultations to engender mutually adjusted and context-driven interactions meaningful to writers’ development during virtual tutoring. While earlier studies have critiqued asynchronous tutoring for its inability to efficiently promote the writing center philosophy, the inevitability of writing centers’ transition to online modes due to the global COVID-19 pandemic warrants that writing center scholarship rethink the effectiveness of these online spaces. This study utilizes a discourse-analytic approach to analyze textual data collected from both WCONLINE and drafts I, the tutor, worked on. Individual interviews are also collected to ascertain …

Stand Up And Be Counted: Using Traffic Cameras To Assess Voting Behavior In Real Time, Bryce J. Dietrich, Hyein Ko, Payel Sen

Purdue University Libraries Open Access Publishing Fund

Despite their ubiquity, few have used traffic camera networks for social science research. Using 1,312,977 images collected from 768 London-based cameras leading up to the 2015 UK general election, this study not only demonstrates how traffic camera data can be used to effectively measure same-day turnout, but we also provide ways such data can be used to assess political behavior more broadly. Such automated enumeration is especially important in countries where official results are only returned for the current election, making it difficult for those interested in assessing turnout at lower levels of aggregation, even when those elections are next …

Clcweb Call For Papers: Ai And/As Form

CLCWeb Calls for Papers

We are now several years into the growing interest in “generative AI” that followed the introduction of transformer-based Large Language Models (LLMs) and text-to-image generators (Stable Diffusion, DALL-E), and more than a year from the explosive public release of ChatGPT on November 30, 2022. This special issue of CLCWeb is about how theorists and analysts of culture are approaching formal questions in the context of technologies of machine learning and generative AI, and, also, conversely, about how to theorize AI’s forms.

We seek contributions to these debates that address the question of AI and/as form, with the term “form” …
