Department of Civil and Environmental Engineering: Faculty Publications

This study investigated the positive effect of the combined use of recycled asphalt shingles (RASs) and municipal solid waste incineration (MSWI) bottom ash (B.A.) in asphalt concrete, which contributes to enhanced sustainability in pavement engineering. In addition, unlike traditional approaches that employ individual recycling material in hot mix asphalt (HMA), the combined use of the two waste materials maximizes the mechanical performance of the asphalt mixture. The addition of RAS (with 30–40% aged binder) as an additive generally enhances the strength/stiffness of the asphalt mixture. The high porosity/absorption of MSWI BA results in an additional amount of liquid asphalt binder …

People, Processes, Systems, And Leadership — Keys To Organizational Performance, Cam Caldwell, Khalfan R. Al Asmi, Zulaikah Albusaidi, Rayan Esmaail

The Journal of Values-Based Leadership

Current evidence about successful organizations emphasizes the importance of integrated organizational factors that combine to convey a consistent message to employees that is the essence of an effective organizational culture (Beer, 2009; Shein & Schein, 2016). Although there is much that is positive about the achievements that some organizations are making to create a sustainable organizational culture, there is also overwhelming evidence that organizations and their leaders are struggling to earn the commitment and followership of their employees (Clifton & Harter, 2019; Edelman, 2023).

Robust Gasification Trial Results For A Variety Of Difficult-To-Recycle Packaging-Related Materials, Bruce A. Welt

Journal of Applied Packaging Research

Currently, recycling requires nearly absolute sorting of materials to accommodate the limited capabilities of existing recycling infrastructure. Whether a material is “recyclable” depends more on the method of recycling than the material itself. Our dependence upon sorting has limited success of recycling and has stifled our ability to achieve circular economy sustainability with plastic packaging materials. Our dependence upon sorting is rooted in our material-specific recycling processes. However, newer robust recycling processes are commercially available that reduce or eliminate the need to sort waste, and can convert mixed waste into primary feedstock chemicals, such as methanol for subsequent manufacture of …

Critically Analyzing The Meanings Of “Critical” Media Literacy, W. James Potter

Journal of Media Literacy Education

This study provides a critical analysis into how authors of publications about critical media literacy express what they mean by the term. The use of multiple strategies to examine the degree to which these authors exhibit a sharing of meaning led to the conclusion that there are far more differences than commonalities across definitions of critical media literacy. The implications of this conclusion raise important questions about the value of a literature where authors seem to express so many different meanings for the concept that they use to label their common concern.

The Complexities Of Green Infrastructure, Troy Weber

Purdue Journal of Service-Learning and International Engagement

The Wabash River is the most extensive river system in Indiana. The river drains two-thirds of Indiana’s 92 counties, which can have issues associated with stormwater runoff (Weist, 1981). As precipitation runs off impervious surfaces, it can carry high concentrations of pollutants, such as excess nitrogen and phosphorus, pet waste, and automobile fuel. Prior to impervious runoff entering the river, preexisting contaminants include industrial waste (acid mine drainage and oil field brines), municipal waste, and sediment (Weist, 1981). Thus, stormwater runoff can negatively impact the Wabash River watershed. On top of this pollution, Lafayette and West Lafayette have combined sewer …
