Risk Perception And Response Among International Students Of The University Of Southern Mississippi, Elida Lopes Souza Rocha

Master's Theses

Given the exposure of university campuses to hazards, disaster mitigation is a critical element of higher education policy. Although U.S. higher education institutions are leaders in the global education market, emergency warning systems give little consideration to how international students perceive risk, prepare for hazards, or access warning technologies available to them. This poses several questions regarding the suitability of hazards mitigation practices and the welfare of international students.

This thesis investigates the relationship between USM international students and natural hazards. Responses from online surveys and semi-structured interviews data were analyzed through qualitative and quantitative methods to document the extent …

Spatial Proximity Matters: A Study On Collaboration, Arianna Salazar Miranda, Matthew Claudel

Geography Faculty Publications and Presentations

As scientific research becomes increasingly cross-disciplinary, many universities seek to support collaborative activity through new buildings and institutions. This study examines the impacts of spatial proximity on collaboration at MIT from 2005 to 2015. By exploiting a shift in the location of researchers due to building renovations, we evaluate how discrete changes in physical proximity affect the likelihood that researchers co-author. The findings suggest that moving researchers into the same building increases their propensity to collaborate, with the effect plateauing five years after the move. The effects are large when compared to the average rate of collaboration among pairs of …

A Novel Big Data Approach To Measure And Visualize Urban Accessibility, Yuqin Jiang, Diansheng Guo, Zhenlong Li, Michael E. Hodgson

Faculty Publications

Accessibility is a topic of interest to multiple disciplines for a long time. In the last decade, the increasing availability of data may have exceeded the development of accessibility modeling approaches, resulting in a modeling gap. In part, this modeling gap may have resulted from the differences needed for single versus multimodal opportunities for access to services. With a focus on large volumes of transportation data, a new measurement approach, called Urban Accessibility Relative Index (UARI), was developed for the integration of multi-mode transportation big data, including taxi, bus, and subway, to quantify, visualize and understand the spatiotemporal patterns of …

Modeling The Spatial Distribution Of The Current And Future Ecosystem Services Of Urban Tree Planting In Chicopee And Fall River, Massachusetts, R. Moody, N. Geron, M. Healy, J. Rogan, Deborah Martin

Geography

Mature urban tree canopy cover disrupts the local effects of urban heat islands and provides important ecosystem services such as energy savings through evaporation and shading, pollution removal, storm runoff control, and carbon sequestration. Sustainable urban tree canopy relies on the planting of juvenile trees. Typically, tree planting programs are only evaluated by the number of trees planted and there is a lack of analysis of juvenile trees post-planting. This study examines the value and distribution of energy savings provided by juvenile trees and how that value changes considering predicted tree growth and mortality by 2050. Using i-Tree Eco software, …

Experiences With Flood And Perceptions Of Flood Risk Among Members Of The Filipino American Community In Virginia Beach, Virginia, Anjelica Pascual Petsch

Institute for the Humanities Theses

The Filipino Americans living in Hampton Roads, Virginia have comprised of almost 2% of the region’s overall population, and 5.3% of the population in Virginia Beach, Virginia (United States Census Bureau, 2019) (Greater Hampton Roads Connects, 2021). Filipino Americans in Hampton Roads, like the rest of the population, are equally vulnerable to experiencing flooding when commuting to and from work or simply traveling around town, but previous research and surveys from the Hampton Roads Region have failed in their ability to capture this cultural diversity within perception of flood risk.

Forced And Unforced Permafrost Changes In The Northern Hemisphere During 1901-2100, Hong Guo

Graduate Theses and Dissertations

Permafrost regions are very sensitive to rapid changes in climate and environment. In recent decades, there has been growing interest to better understand the permafrost degradation over the Northern Hemisphere in the context of human-induced climate change. Understanding permafrost dynamics is not only important for infrastructure but also for environmental protection in cold regions. In-situ permafrost measurements are important for assessing permafrost conditions. However, direct permafrost observations are sparse and asymmetrical in both spatial and temporal coverage. Active layer thickness (ALT) modeling is another approach that can overcome many of these limitations, but the models have large uncertainty in predicting …

Shipboard Lidar As A Tool For Remotely Measuring The Distribution And Bulk Characteristics Of Marine Particles, Brian Leigh Collister

OES Theses and Dissertations

Light detection and ranging (lidar) can provide remote estimates of the vertical distribution of optical properties in the ocean, potentially revolutionizing our ability to characterize the spatial structure of upper ocean ecosystems. However, challenges associated with quantifying the relationship between lidar measurements and biogeochemical properties of interest have prevented its adoption for routinely mapping the vertical structure of marine ecosystems. To address this, we developed a shipboard oceanographic lidar that measures attenuation (α) and linear depolarization (δ) at scales identical to those of in-water optical and biogeochemical measurements. The instrument’s ability to resolve the distribution of optical and biogeochemical properties …

Data-Driven Operational And Safety Analysis Of Emerging Shared Electric Scooter Systems, Qingyu Ma

Computational Modeling & Simulation Engineering Theses & Dissertations

The rapid rise of shared electric scooter (E-Scooter) systems offers many urban areas a new micro-mobility solution. The portable and flexible characteristics have made E-Scooters a competitive mode for short-distance trips. Compared to other modes such as bikes, E-Scooters allow riders to freely ride on different facilities such as streets, sidewalks, and bike lanes. However, sharing lanes with vehicles and other users tends to cause safety issues for riding E-Scooters. Conventional methods are often not applicable for analyzing such safety issues because well-archived historical crash records are not commonly available for emerging E-Scooters.

Perceiving the growth of such a micro-mobility …

Assessing Population Exposure To Coastal Flooding Due To Sea Level Rise, Matthew E. Hauer, Dean Hardy, Scott A. Kulp, Valerie Mueller, David J. Wrathall, Peter U. Clark

Faculty Publications

The exposure of populations to sea-level rise (SLR) is a leading indicator assessing the impact of future climate change on coastal regions. SLR exposes coastal populations to a spectrum of impacts with broad spatial and temporal heterogeneity, but exposure assessments often narrowly define the spatial zone of flooding. Here we show how choice of zone results in differential exposure estimates across space and time. Further, we apply a spatio-temporal flood-modeling approach that integrates across these spatial zones to assess the annual probability of population exposure. We apply our model to the coastal United States to demonstrate a more robust assessment …

Nuanced Networks: How Social Relationships And Power Influence Participation In Private Lands Conservation Programs, Ellen Loechner

Geography ETDs

Because the majority of land in the Midwestern United States is privately owned, the responsibility for creating and maintaining space for wildlife conservation falls upon private landowners. Numerous state and federal agencies and non-governmental organizations (NGOs) host private lands conservation programs that offer landowners financial and technical support to complete conservation projects on their property (Echols, Front, and Cummins 2019). While the individual motivations and priorities of a landowner may inform how they use and manage their property, a landowner’s ability to connect with the agricultural and conservation communities may determine if they have the opportunity to participate in these …

Factors Facilitating And Challenges Facing Community-Based Interventions In Improving Antenatal Care In Rural Tanza, Stephen Maluka, Chakupewa J. Mpambije

Journal of Humanities and Social Sciences

The improvement of antenatal care has remained a topical global concern as signalled by maternal deaths, which have remained unacceptably high, especially in low- and middle income countries. In response to this concern, community-based interventions through women’s groups have been implemented to improve antenatal care; and have shown promising results in rural settings. However, factors contributing to the success or failure of these interventions vary across geographical settings, thereby necessitating area specific considerations. This paper sets out to unveil significant facilitators and barriers to the implementation of women’s group interventions in Tanzania. A qualitative case study design was employed involving …

Market-Driven Rice Farming And Water Use Change In Mbarali District From The Mid-1980s To The 2010s, George K. Ambindwile

Journal of Humanities and Social Sciences

This paper examines the effects of market-driven rice farming on the use of water in Mbarali District from about the mid-1980s to 2010s. It specifically traces the development of both peasant and state rice farming and their subsequent effects on water use in the district. The study is essentially qualitative, although in some cases it uses quantitative data to validate its arguments. Thus, it adopts political economy and historical ecology theories to understand changes brought by market-driven rice farming; and the ways peasants struggled to accommodate those changes in their agricultural practices. The area of study included six villages, namely …
