This paper provides the groundwork for educators in business schools to reconsider the conventional approach to teaching qualitative methods. It draws on my personal and professional experience as a key resource to shape its examination of doctoral education in conducting qualitative research. The paper offers points of reflection on the struggle students may face in conducting rigorous qualitative research without appropriately understanding the influence of self with previous experience, preconceived ideas, …

“Urban Renewal” Surrounding Florida Solar Plants: A Study On Low-Carbon Gentrification, Megan Amber Grove

USF Tampa Graduate Theses and Dissertations

Renewable energy and sustainable living are growing trends in Florida as the state “develops” rural landscapes and “redevelops” urban ones, resulting in neighborhood changes, including displacement of low-income and minority populations (LIMP). Solar energy has not historically been a root cause of such changes, but in recent years it has increasingly accompanied neighborhood development which prioritizes the interests of the elite and middle class. As such, it has become a contributor to “urban renewal,” which must be addressed to avoid future LIMP displacement. This study used geospatial and data science technologies and techniques to empirically explore and analyze urbanization and …

Exploring The Dynamics Of Cross-Boundary Interactions In Qinglinkou, China: The Perspective Of Networks Of Second-Home Owners, Meiling Wu, Mengqiu Cao, Jiuxia Sun

Research Collection School of Social Sciences

Cross-boundary interactions between second-home owners and local are complex over time–networks form and evolve within second-home owners and between owners and locals, each with its deliberately selective inclusion and exclusion. However, little attention has been paid to this phenomenon in the literature. This study, based on social network analysis alongside qualitative interviews, explores the dynamics of interactions between second-home owners and locals by analysing the networks formed by second-home owners in Qinglinkou, China. The ways in which second-home owners maintain and strengthen pre-existing networks with other owners and forge new links with locals, shape the cross-boundary interactions between the two …

Sabkha (salt flat) is a geological feature composed of saline and salt marshes that typically occur in shallow or coastal environments within arid and semi-arid climates. Traditional methods of measuring soil salinity are time-consuming and labor-intensive, making remote sensing techniques an attractive alternative. This study employed a hyperspectral sensor specifically the SVC-XHR-1024i to …

Relocating Lubra Village And Visualizing Himalayan Flood Damages With Remote Sensing, Ronan Wallace, Yungdrung Tsewang Gurung, Ryan Kastner

Journal of Critical Global Issues

As weather patterns change worldwide, isolated communities impacted by climate change go unnoticed and we need community-driven solutions. In Himalayan Mustang, Nepal, indigenous Lubra Village faces threats of increasing flash flooding. After every flood, residual muddy sediment hardens across the riverbed like concrete, causing the riverbed elevation to rise. As elevation increases, sediment encroaches on Lubra’s agricultural fields and homes, magnifying flood vulnerability. In the last monsoon season alone, the Lubra community witnessed floods swallowing several agricultural fields and damaging two homes. One solution considers relocating the village to a new location entirely. However, relocation poses a challenging task, as …

Recovery Of Microtopography Following Prairie Restoration: Implications For Biodiversity Monitoring, Karli Cich, Scott Powell

The Geographical Bulletin

Tallgrass prairies are often restored from agricultural fields where the natural microtopography has long since been removed. Therefore, our study investigates the degree to which restored prairies recover microtopography. Differences in microtopography were measured using precise elevation data collected from LiDAR to compare differences in microtopography between crop fields, fallow fields, newer restored prairies, and older restored prairies. We also compared plant biodiversity indices between newer and older restored prairies using nested plot vegetation sampling. Our first research question is how microtopography differs between the sites. Our results show that older restored prairies had the most microtopographic variation, followed by …

Modeling The Impact Of Ocean Temperature Increases On The Distribution Of Seagrasses Around The Korean Peninsula Using A Machine Learning Technique, Jina Jang, Seohyeon Kim, Jeong Seong

The Geographical Bulletin

Seagrasses are important resources which form a vital part of the ocean ecosystem. They are also considered blue carbon because of their capability of sequestrating carbon. Seagrass distribution can be affected by many factors including ocean temperature. It is highly likely that recent climate change may increase ocean temperature significantly in East Asia and consequently alter seagrass distribution patterns. This study aims at predicting the impact of ocean temperature increases on seagrass habitats around the Korean Peninsula. Using the Maximum Entropy (MaxEnt) Model, seagrass habitat distributions were modeled when sea temperature rises by 1°C, 2°C, 3°C, and 4°C. Results show …
