Introduction To Big Data Computing For Geospatial Applications, Zhenlong Li, Wenwu Tang, Qunying Huang, Eric Shook, Qingfeng Guan

Faculty Publications

The convergence of big data and geospatial computing has brought challenges and opportunities to GIScience with regards to geospatial data management, processing, analysis, modeling, and visualization. This special issue highlights recent advancements in integrating new computing approaches, spatial methods, and data management strategies to tackle geospatial big data challenges and meanwhile demonstrates the opportunities for using big data for geospatial applications. Crucial to the advancements highlighted here is the integration of computational thinking and spatial thinking and the transformation of abstract ideas and models to concrete data structures and algorithms. This editorial first introduces the background and motivation of this …

Easily Overlooked: Modelling Coastal Dune Habitat Occupancy Of Threatened And Endangered Beach Mice (Peromyscus Polionotus Spp.) Using High-Resolution Aerial Imagery And Elevation Models Of The Northern Gulf Of Mexico, Wesley Burger

Theses and Dissertations

The Gulf of Mexico dune system is a broad and dynamic environment that varies greatly in geomorphology and vegetative composition across the Gulf coastline. Beach mice (Peromyscus polionotus spp.) are an endangered species that rely on coastal habitat structure. I hypothesized that beach mouse occupancy would be dependent upon coastal dune land cover and landform features. I identified coastal landforms using high-resolution elevation data and landform models in GRASS GIS and identified coastal dune vegetation classes using high-resolution aerial imagery and object oriented vegetation classification. These features were used to create a dynamic occupancy model to determine occupancy patterns in …

Characterization Of Severe Asthma Worldwide: Data From The International Severe Asthma Registry, E Wang, Me Wechsler, Tn Tran, Lg Heaney, Rc Jones, An Menzies-Gow, J Busby, Dj Jackson, Pe Pfeffer, Ck Rhee, Ys Cho, Gw Canonica, E Heffler, Pg Gibson, M Hew, M Peters, Es Harvey, M Alacqua, J Zangrilli, L Bulathsinhala, Va Carter, I Chaudhry, N Eleangovan, N Hosseini, Rb Murray, Db Price

Peninsula Medical School

BackgroundClinical characteristics of the international population with severe asthma are unknown. Intercountry comparisons are hindered by variable data collection within regional and national severe asthma registries. We aimed to describe demographic and clinical characteristics of patients treated in severe asthma services in the United States, Europe, and the Asia-Pacific region.MethodsThe International Severe Asthma Registry retrospectively and prospectively collected data in patients with severe asthma (≥ 18 years old), receiving Global Initiative for Asthma (GINA) Step 5 treatment or with severe asthma remaining uncontrolled at GINA Step 4. Baseline demographic and clinical data were collected from the United States, United Kingdom, …

Active Learning In Accounting And The Impact On Student Engagement, Daniel King

Conference papers

This paper reports on a range of active learning and online strategies that were introduced into an introductory accounting module. Up until recently the traditional lecture format, where students sit passively and the lecturer delivers the lecture, has been the dominant format in higher education. However, research has shown that formats which provide students with a more active and engaged learning environment result in deeper learning The active learning strategies discussed in this paper were based around an "Active Learning Exercise" where students worked in a cooperative group environment. Before, during and after the "Active Learning Exercise" an additional range …

Human Dimensions Research For Informed Decisions About Aquatic Restoration In New Hampshire: Environmental Justice In Implementation Of Compensatory Mitigation, Simone Tania Chapman

Master's Theses and Capstones

New Hampshire’s aquatic resources provide many important ecosystem services and values, such as recreation, wildlife habitat, flood storage, nutrient reduction, community identity and aesthetic enjoyment. However, the many competing interests that seek to benefit from New Hampshire’s aquatic resources present challenges for efforts to steward public aquatic resources in the public interest. This thesis presents findings about the environmental justice outcomes of New Hampshire’s compensatory mitigation program, the Aquatic Resource Mitigation (ARM) fund, to inform aquatic restoration policy.

Previous studies have found evidence that aquatic restoration programs can lead to systemic resource relocation and patterns of inequality in outcomes. Using …
