How Much Do Purdue's Trees Weigh? Estimating Biomass In Urban Areas, Jacob Klaybor, Gillian Clark, Brady Hardiman

Purdue GIS Day

Vegetation plays an important role in urban areas by reducing the urban heat island effect, sequestering carbon emissions, and providing socioeconomic benefits to the surrounding areas. However, the roles and distributions of urban forests have historically been ignored or underestimated. This presentation uses the campus of Purdue University in West Lafayette, IN, as a case study to quantify the aboveground vegetative biomass of campus trees. Tree biomass is calculated with data from the Purdue Arboretum and family-specific allometric relationships based on each tree's diameter at breast height to estimate the total carbon storage available within campus trees. Biomass estimates of …

Economic Resilience And Diversity In Indiana From 2002 To 2016, Santiago Ruiz, Michael Wilcox, Indraneel Kumar

Purdue GIS Day

It is well accepted that recessionary shocks affect long-term patterns of economic growth within regions. For this reason, it is important to understand how regional economies recover and in which extent a shock could be an economic burden in long term. A relevant variable to measure shock’s impact is employment, for two reasons. First, past recessions suggested that in most cases, the decline in employment tended to be deeper than in output. Second, layoffs of workers are key forms of adjustment to which employees seek to reduce costs. Given these, our research aims to understand shifts in employees during, after …

The Geopolitics Of Canadian Defense White Papers: Lofty Rhetoric And Limited Results, Bert Chapman

Libraries Faculty and Staff Scholarship and Research

As the United States northern neighbor, Canada serves as a NATO ally and a strategic partner with Washington through the North American Aerospace Defense Command (NORAD). Canadian forces have fought honorably and bravely in concert with American forces in many wars. Canada's government, however, has been less consistent in promoting a credible vision of Canadian national security policy and geopolitical interests in its defense white papers. These documents have often contained idealistic rhetoric about adhering to a rules-based international order and defending freedom. In reality, Canadian governments of varying political parties have consistently failed to provide the sustained funding and …

Housing Diversity In Children’S Literature, Carla Earhart

Charleston Library Conference

Previous studies have examined diversity in children’s literature: Gender diversity, racial diversity, religious diversity, and diversity in family composition. This project examines an often overlooked diversity issue in children’s literature: Housing diversity. In the stories they read and the accompanying images, children need to see a variety of housing environments and need to see the settings and the people portrayed in a positive manner.

Renting an apartment is an increasingly popular housing option for many families. However, many children’s books glamorize living in a traditional house. Using a rubric designed by the course instructor, students in a university immersive learning …

Acoustic Signatures Of Habitat Types In The Miombo Woodlands Of Western Tanzania, Sheryl Vanessa Amorocho, Dante Francomano, Kristen M. Bellisario, Ben Gottesman, Bryan C. Pijanowski

The Summer Undergraduate Research Fellowship (SURF) Symposium

The Miombo Woodlands of Tanzania comprise several habitat types that are home to a great number of flora and fauna. Understanding their responses to increasing human disturbance is important for conservation, especially in places where people depend so directly on their local ecosystem services to survive. Soundscapes are a powerful approach to study complex biomes undergoing change. The sounds emitted by soniferous fauna characterize the acoustic profile of the landscapes they inhabit such that habitats with the highest acoustic abundance are considered as the most diverse and possibly more ecologically resilient. However, acoustic variability within similar habitat types may pose …

How To Enhance Interdisciplinary Competence—Interdisciplinary Problem-Based Learning Versus Interdisciplinary Project-Based Learning, Mirjam Brassler, Jan Dettmers

Interdisciplinary Journal of Problem-Based Learning

Interdisciplinary competence is important in academia for both employability and sustainable development. However, to date, there are no specific interdisciplinary education models and, naturally, no empirical studies to assess them. Since problem-based learning (PBL) and project-based learning (PjBL) are learning approaches that emphasize students’ collaboration, both pedagogies seem suitable to enhance students’ interdisciplinary competence. Based on the principle of constructive alignment and four instructional principles on interdisciplinary learning, this paper proposes that students profit more from interdisciplinary PBL (iPBL) than interdisciplinary PjBL (iPjBL). A pre-post study was conducted with a sample of 95 students participating in iPBL and 183 students …
