Fostering Penetrative Thinking in Geosciences Through Immersive Experiences: A Case Study in Visualizing Earthquake Locations in 3D

Mahda M. Bagher, Pejman Sajjadi, Julia Carr, Peter La Femina and Alexander Klippel
Proceedings of the 6th International Conference of the Immersive Learning Research Network (iLRN 2020)
Thinking in and understanding of three-dimensional structures is omnipresent in many sciences from chemistry to geosciences. Current visualizations, however, are still using two-dimensional media such as maps or three-dimensional representations accessible through two-dimensional interfaces (e.g., desktop computers). The emergence of immersive virtual reality environments, both accessible and of high-quality, allows for creating embodied and interactive experiences that permit for rethinking learning environments and provide access to three-dimensional information through three-dimensional interfaces. However, there is a shortage of empirical studies on immersive learning environments. In response to this shortcoming, this study examines the role of immersive VR (iVR) in improving students’ learning experience and performance in terms of penetrative thinking in a critical 3D task in geosciences education: drawing cross-sections. We developed a pilot study where students were asked to draw cross-sections of the depth and geometry of earth-quakes at two subduction zones after visualizing the earthquake locations either in iVR or 2D maps on a computer. The results of our study show that iVR creates a better learning experience; students reported significantly higher scores in terms of Spatial Situation Model and there is anecdotal evidence in favor of higher reflective thinking in iVR. In terms of learning performance, we did not find a significant difference in the graded exercise of drawing cross-sections. However, iVR seems to have a positive effect on understanding the geometry of earthquake locations in a complex tectonic environment such as Japan. Our results, therefore, add to the growing body of literature that draws a more nuanced picture of the benefits of immersive learning environments calling for larger scale and in-depth studies.

A spatial analysis of COVID-19 period prevalence in US counties through June 28, 2020: Where geography matters?

Feinuo Sun, Stephen A. Matthews, Tse-ChuanYang, Ming-Hsiao Hu
Annals of Epidemiology
Purpose: This study aims to understand how spatial structures, the interconnections between counties, matter in understanding COVID-19 period prevalence across the US.
Methods: We assemble a county-level dataset that contains COVID-19 confirmed cases through June 28, 2020 and various sociodemographic measures from multiple sources. In addition to an aspatial regression model, we conduct spatial lag, spatial error, and spatial autoregressive combined models to systematically examine the role of spatial structure in shaping geographical disparities in COVID-19 period prevalence.
Results: The aspatial ordinary least squares regression model tends to overestimate the COVID-19 period prevalence among counties with low observed rates, but this issue can be effectively addressed by spatial modeling. Spatial models can better estimate the period prevalence for counties, especially along the Atlantic coasts and through the Black Belt. Overall, the model fit among counties along both coasts is generally good with little variability evident, but in the Plain states, model fit is conspicuous in its heterogeneity across counties.
Conclusions: Spatial models can help partially explain the geographic disparities in COVID-19 period prevalence. These models reveal spatial variability in model fit including identifying regions of the country where fit is heterogeneous and worth closer attention in the immediate short term.

Seed source pattern and terrain have scale-dependent effects on post-fire tree recovery

Jamie L. Peeler & Erica A. H. Smithwick
Landscape Ecology
Context: Distance to seed source is often used to estimate seed dispersal—a process needed for post-fire tree recovery. However, distance, especially in mountainous terrain, does not capture pattern or scale-dependent effects controlling seed supply and delivery. Measuring seed source pattern (area and arrangement) could provide insights on how these spatial dynamics shape recovery.
Objectives: We tested metrics and investigated how seed source pattern, tree regeneration traits, scale, and terrain interact to shape post-fire tree recovery. Our research questions were: Does seed source pattern outperform distance when modeling tree species presence and regeneration density? If yes, does seed source pattern have scale-dependent or terrain-dependent effects on regeneration density?
Methods: We measured seed source pattern at nested spatial extents around 71 plots and related measurements to local post-fire tree recovery. We used generalized linear models to test metrics and visualize scale-dependent and terrain-dependent effects on regeneration density.
Results: Distance sufficiently modeled presence, but seed source pattern outperformed distance when modeling regeneration density. Relevant spatial extents and relationships were species-dependent. For wind-dispersed species, regeneration was associated with more seed source area and more complex arrangements, but terrain mediated these relationships. For serotinous and resprouting species, regeneration was associated with less seed source area and less complex arrangements, which are consistent with high-severity burn sites that promote recovery.
Conclusions: Seed source pattern supports spatial resilience and interacts with scale and terrain to shape regeneration density. Accounting for these spatial dynamics could help steward forests facing changing fire regimes.

Informal food chains and agrobiodiversity need strengthening—not weakening—to address food security amidst the COVID-19 crisis in South America

Karl S. Zimmerer & Stef de Haan
Food Security
The COVID-19 crisis is worsening food insecurity by undermining informal food chains. We focus on impacts involving the informal food chains that incorporate the resilience-enhancing biodiversity of food and agriculture known as agrobiodiversity. Our analysis addresses how informal food chains and agrobiodiversity are impacted by policies and interventions amidst COVID-19 disruptions. Our methodology relies on research in Peru with a focus on the cites and surrounding areas of Lima, Arequipa, Cusco, Huancayo, and Huánuco. We extend these insights to similar challenges and opportunities across western South America and other word regions. We utilize the four-part Agrobiodiversity Knowledge Framework to guide our examination of agrobiodiversity-related processes that interconnect governance, nutrition, agroecology, and the COVID-19 pandemic. Our results detail three links of informal food chains that are being disrupted and yet can offer resilience. These are food retailing, logistics and transportation, and seed systems. Utilization of the Agrobiodiversity Knowledge Framework cuts through highly complex issues to elaborate key food-security difficulties facing informal systems and how they can be strengthened to provide more resilience. We identify the specific roles of agrobiodiversity in resilience-enhancing processes that need strategic policy and program support. Results identify ways to augment the resilience of informal food chains using agrobiodiversity and the empowerment of social groups and organizations in urban food systems and rural communities. We conclude that the disruptions triggered by the global COVID-19 pandemic highlight the need to use agrobiodiversity as an instrument for resilience in informal food chains.

From the Head | New online MS in spatial data science | VR brings field sites to students


spatial data science imageMore and more companies are using location data from devices like smartphones and tablets to gain insights into choices consumers make. As the volume and complexity of location data increases, the demand for the professionals with the technical skills to leverage these data is also increasing.

A new degree from Penn State, a master of science in spatial data science, aims to address that growing need.

From the Head: Preparing for fall

There are tremendously geographic and spatial aspects to preparing for a back-to-campus fall at a variety of scales. There is a national and global aspect in places students are coming from when they return and what the coronavirus rates are at their summer residences. There is an almost opposite concern that international students already here who are taking all remote/online coursework may be deported by the federal government—a decision Penn State is studying and challenging.

At a different scale, the classrooms in which we teach have all changed in “size.” Rooms are set at about one-third to one-fifth normal capacity, so popular rooms such as 112 Walker Building—where we hold Coffee Hour talks and large classes—has reduced available seats from 137 to 26. (Classroom capacities are listed on the 25Live website.) In our usual departmental meeting room, 319 Walker Building, capacity shrinks from 35 to 8 people with social distancing in effect.

Yvette Richardson, associate dean; geography’s academic adviser, Jodi Vender; and the registrar set new rooms for all the in-person teaching requests in geography over the past two weeks. I’m pleased to say that 20 of our 37 fall geography courses have some in-person meetings planned (fully in-person, mixed-mode, or hybrid). Some instructors split their class into cohorts to meet with half of the student each day in a new, larger room. We were able to claim 108 Forum Building, which is large enough for the whole GEOG 220 Perspectives on Human Geography class to meet together (its usual 355-seat capacity now accommodates the 54 students with social distancing). If infection rates allow us to feel confident in having instructors and students together, we are ready to meet an uncertain fall.

Here but still ‘there’: Using virtual-reality field trips to enrich education

Classes may have been held remotely during the previous spring semester, but Penn State faculty members found creative ways to bring field trips to their students, even when they couldn’t necessarily bring students out into the field. Two courses in Penn State’s College of Earth and Mineral Sciences employed virtual reality field trips last semester to continue delivering the same high degree of academic quality that Penn State is known for around the world.

“Fully immersive virtual reality, where everything is interactive, is the ideal,” said Alexander Klippel, professor of geography and director of the Center for Immersive Experiences. “But that requires special equipment that would not work in the new remote teaching environment.”


Communal Innovations: Inspiring Neighborhoods of Hope and Advocacy

Rachel A. Smith, Youllee Kim, Stephen A. Matthews, Eleanore D. Sternberg, Dimi Théodore Doudou, and Matthew B. Thomas
Journal of Health Communication
Innovations promise a better future, which may generate feelings of hope and inspire advocacy. Some innovations are more communal in nature: attempting to address a social problem, through community engagement and wide-spread adoption. For such innovations, the social processes that involve collective aspects of community life may play important roles in fostering hope and interpersonal advocacy. This study uses communication infrastructure theory and discrete emotions theory to investigate hope and advocacy within a field trial for a salient, visible, community-bound innovation to reduce transmission of malaria. Heads of households in one community (N = 119) in West Africa were interviewed. Results showed that innovation hope was predicted by appraisals of innovation attributes. Better appraisals of the innovation’s attributes, greater perceived collective efficacy, and recent malaria illness predicted more innovation advocacy. The spatial analysis showed that innovation advocacy was geographically clustered within the community, but hope was not. The implications for theory and practice are discussed.

Patch-scale selection patterns of grazing herbivores in the central basalt plains of Kruger National Park

DOI: 10.2989/10220119.2020.1733084
Large herbivores form an essential component in the ecosystem, because of the impact that they have on their surrounding habitat. In this study, we aimed to evaluate some of the mechanisms behind how herbivores select forage at a patch scale. Thirty-six experimental plots were established and fitted with camera traps in Kruger National Park to test forage selectivity by grazers. Plots were manipulated by clearing with a brush cutter and the application of fertiliser. We used generalised linear models to detect trends in probability of occurrence by seven grazing herbivore species using camera trap data. Our results showed that season was a major determinant of species distribution, especially those that are not obligate grazers or feed exclusively in the 0.5 km to 2 km zone from water. We found that most selective feeding occurred in the late wet season when water would be more evenly distributed across the landscape and forage resources close to water would have had the chance to recover from depletion, as a result of dry season use. This has implications for the distribution of artificial water points across the landscape, because areas of reserve forage must be maintained to alleviate grazing pressure close to water.

Climate change is also a racial justice problem

Gregory Jenkins is interviewed

If humanity is going to effectively tackle climate change, scientists and activists told me, it’s a question we have to answer. You can’t build a just and equitable society on a planet that’s been destabilized by human activities, they argue. Nor can you stop the world from warming without the experience and the expertise of those most affected by it.

Summer Series on questions of geo-ethics and Human Rights highlighted by COVID-19 Conditions

This series developed from discussions that took place at the AAG’s Virtual Annual Meeting, April 6-10, 2020, during publicly available panels of the breaking theme “Geographers Respond to COVID-19”. The panels were set up by AAG specialty groups and their chairs who wanted to initiate discussions about the ongoing pandemic using a geographic lens, showcase the application of geography to urgent issues, and to learn from the evolving circumstances to build future preparedness. Recordings of the panels are still available for anyone to watch.


Conceptual Links between Landscape Diversity and Diet Diversity: A Roadmap for Transdisciplinary Research

Malnutrition linked to poor quality diets affects at least 2 billion people. Forests, as well as agricultural systems linked to trees, are key sources of dietary diversity in rural settings. In the present article, we develop conceptual links between diet diversity and forested landscape mosaics within the rural tropics. First, we summarize the state of knowledge regarding diets obtained from forests, trees, and agroforests. We then hypothesize how disturbed secondary forests, edge habitats, forest access, and landscape diversity can function in bolstering dietary diversity. Taken together, these ideas help us build a framework illuminating four pathways (direct, agroecological, energy, and market pathways) connecting forested landscapes to diet diversity. Finally, we offer recommendations to fill remaining knowledge gaps related to diet and forest cover monitoring. We argue that better evaluation of the role of land cover complexity will help avoid overly simplistic views of food security and, instead, uncover nutritional synergies with forest conservation and restoration.

Hunter and Non-Hunter Perceptions of Costs, Benefits, and Likelihood of Outcomes of Prescribed Fire in the Mid-Atlantic Region

In the mid-Atlantic region, prescribed fire is as an important tool for natural resource managers to achieve a variety of outcomes, including the management of wildlife habitat and wildfire risk reduction. However, little research has been conducted in this region to help inform managers about public perceptions and acceptance of prescribed fire. In this research, data from intercept surveys of hunter and non-hunters on public lands in New Jersey and Pennsylvania are used to compare perceptions of perceived costs, benefits, and likelihood of outcomes for these groups related to prescribed fire. Results show that hunters generally had lower levels of perceived costs and likelihood of negative outcomes from prescribed fire than non-hunters. From this, managers using prescribed fire in these areas can better understand public perceptions, differences among recreation users, and possibly better communicate about using prescribed fire as a tool for managing resources.

Shared discovery: A process to coproduce knowledge among scientists, policy makers, and stakeholders for solving nutrient pollution problems

Matthew B. Royer, Robert P. Brooks, James S. Shortle, Susan Yetter
Journal of Environmental Quality
There is growing recognition of the importance of involving stakeholders in solution‐oriented multidisciplinary environmental research projects. Management of nutrients to address water pollution is a wicked problem requiring multidisciplinary research and participation of stakeholders. Here, we frame participatory research as shared discovery , a deliberative, focused engagement process that serves as a directional guide for how research unfolds during the entire span of a project. We explore its application within a 5‐yr, multidisciplinary research project seeking innovative solutions to nutrient management challenges in four agriculturally influenced small watersheds in the Chesapeake Bay basin. This process involved deliberate development of a stakeholder engagement strategy and structure, which included a specific research team dedicated to implementing shared discovery throughout. Recognizing that stakeholders involved in nutrient and watershed management engage at multiple scales, we developed a biscalar approach to engage stakeholders at both a regional or state policy level and within the local study watersheds. Early collaboration allowed stakeholders to be participatory in developing research questions and shaping research design, which made research results more applicable to the identified problems. The biscalar framework for engagement was a novel approach that allowed researchers to incorporate both broader policy concepts into research and local concerns and concepts specific to the small study watersheds, allowing solutions to be tailored to local needs. Although infusing research with stakeholder engagement and input from the outset is a time‐consuming process, it bolsters research design and products and leads to greater application of research to solve nutrient pollution—a wicked problem indeed.

Who is resilient in Africa’s Green Revolution? Sustainable intensification and Climate Smart Agriculture in Rwanda

Nathan Clay, Karl S. Zimmerer
Land Use Policy
Under the banner of a “New Green Revolution for Africa,” agricultural intensification programs aim to make smallholder agriculture more productive as well as “climate smart”. As with Green Revolutions in Asia and Mexico, agricultural innovations (hybrid seeds, agronomic engineering, market linkages,and increased use of fertilizer and pesticides) are promoted as essential catalysts of agriculture-led economic growth. Intensification programs are now frequently linked to Climate Smart Agriculture (CSA), which attempts to build resilience and reduce greenhouse gas emissions while increasing crop yields. This article considers who and what is resilient in Africa’s Green Revolution. We report on a multi-season study of smallholder food producers’ experiences with Rwanda’s Crop Intensification Program (CIP) and related policies that aim to commercialize subsistence agriculture while implementing CSA. . We suggest that there are fundamental limits to the climate resilience afforded by CSA and development efforts rooted in Green Revolution thinking. Our findings illustrate that such efforts foreground technology and management adjustments in ways that have reduced smallholder resilience by inhibiting sovereignty over land use, decreasing livelihood flexibility, and constricting resource access. We put forth that rural development policies could better promote climate-resilient livelihoods through: 1) adaptive governance that enables smallholder land use decision-making; 2) support for smallholder food producers’ existing agro-ecological strategies of intensification; 3) participatory approaches to visualize and correct for inequalities in local processes of social-ecological resilence Such considerations are paramount for meeting the United Nations Sustainable Development Goals and building climate-resilient food systems.

Participatory seed projects and agroecological landscape knowledge in Central America

DOI: 10.1080/14735903.2020.1775930
Participatory projects supporting the farmer-based seed management of agrobiodiverse varieties including landraces have proliferated globally in response to nutritional insecurity and climate change. This research examines the agroecological landscape knowledge of farmers in a recent participatory seed project using the tricot approach in Central America. Over 800 smallholder farmers in Nicaragua facilitated on-farm trials of diverse common bean varieties that are nutritiously valuable and potentially well-adapted to increased temperatures and variable precipitation. Our article integrates relevant research concepts in a case study of the agroecological landscape knowledge of 52 participating farmers. Participatory sketch maps, transect walks, and semi-structured interviews were used to identify key areas of farmers’ agroecological landscape knowledge in crop and seed management. Results indicate the prevalence of nine themes of farmer agroecological landscape knowledge. This landscape knowledge exerts major influence on the choice, placement, and management of common bean varieties and associated land use decisions. Our analysis reveals that farmers use this knowledge to manage their landholdings as landscapes of agroecological interactions that guide seed and variety management and affect potential sustainability. Results demonstrate that local agroecological landscape learning is strengthened through and benefits participatory seed projects.

The geography of sentiment towards the Women’s March of 2017

Felmlee DH, Blanford JI, Matthews SA, MacEachren AM
The Women’s March of 2017 generated unprecedented levels of participation in the largest, single day, protest in history to date. The marchers protested the election of President Donald Trump and rallied in support of several civil issues such as women’s rights. “Sister marches” evolved in at least 680 locations across the United States. Both positive and negative reactions to the March found their way into social media, with criticism stemming from certain, conservative, political sources and other groups. In this study, we investigate the extent to which this notable, historic event influenced sentiment on Twitter, and the degree to which responses differed by geographic area within the continental U.S. Tweets about the event rose to an impressive peak of over 12% of all geo-located tweets by mid-day of the March, Jan. 21. Messages included in tweets associated with the March tended to be positive in sentiment, on average, with a mean of 0.34 and a median of 0.07 on a scale of -4 to +4. In fact, tweets associated with the March were more positive than all other geo-located tweets during the day of the March. Exceptions to this pattern of positive sentiment occurred only in seven metropolitan areas, most of which involved very small numbers of tweets. Little evidence surfaced of extensive patterns of negative, aggressive messages towards the event in this set of tweets. Given the widespread nature of online harassment and sexist tweets, more generally, the results are notable. In sum, online reactions to the March on this social media platform suggest that this modern arm of the Women’s Movement received considerable, virtual support across the country.

Characterizing traveling fans: a workflow for event-oriented travel pattern analysis using Twitter data

DOI: 10.1080/13658816.2020.1770259
Characterizing event attendees’ travel patterns is key to understanding the dynamics of social events in cities. However, the scientific investigation of event travel patterns has been hindered by the difficulty in gathering travel diaries of participants. Geotagged microblogs provide new opportunities for studying event travel patterns by offering rich locational and semantic information of attendees. Here, we develop, implement, and apply a workflow to characterize travel behaviors of event attendees with geotagged Twitter data, using college football events as a case study. The workflow includes five steps: 1) filtering event attendees using real-time geotagged tweets, 2) identifying origins of the event attendees using historical timeline tweets, 3) identifying past sports-related activities at travel destinations using topic modeling, 4) computing user movement features using origin-destination travel flows, and 5) identifying atypical travel patterns to characterize event attendees. The travel patterns uncovered in the study offer insights into user interests and travel behaviors related to sporting event attendance. The findings demonstrate that our method holds promise in revealing long-term event travel patterns (not limited to sporting events) through the use of geotagged microblogs.

Multiple geometry atmospheric correction for image spectroscopy using deep learning

Xu, F., Cervone, G., Franch, G., Salvador, M.
Journal of Applied Remote Sensing
doi: 10.1117/1.JRS.14.024518
The goal of this research is to develop a general deep learning solution for atmospheric correction and target detection using multiple hyperspectral scenes. It is assumed that the scenes differ only in range and viewing angles, that they are acquired in rapid sequence using an airborne sensor orbiting a target, and that the target and the atmosphere remain invariant within the time scale of the collection. Several hundred thousand hyperspectral simulations were performed using the MODTRAN model and were used to train the deep learning solution, as well as to validate the proposed method. The input to the deep learning solution is a matrix of the simulated radiances at the sensor as function of wavelength and elevation angles. The output is atmospheric upwelling, downwelling, and transmission. This solution is repeated for all or a subset of pixels in the scene. We focus on emissive properties of targets, and simulations are performed in the longwave infrared between 7.5 and12μm. Results show that the proposed method is computationally efficient and it can characterize the atmosphere and retrieve the target spectral emissivity within one order of magnitude errors or less when compared with the original MODTRAN simulations.

Spatiotemporal event detection: a review

The advancements of sensing technologies, including remote sensing, in situ sensing, social sensing, and health sensing, have tremendously improved our capability to observe and record natural and social phenomena, such as natural disasters, presidential elections, andi nfectious diseases. The observations have provided an unprecedented opportunity to better understand and respond to the spatiotemporal dynamics of the environment, urban settings, health and disease propagation, business decisions, and crisis and crime. Spatiotemporal event detection serves as a gateway to enable a better understanding by detecting events that represent the abnormal status of relevant phenomena. This paper reviews the literature for different sensing capabilities, spatiotemporal event extraction methods, and categories of applications for the detected events. The novelty of this review is to revisit the definition and requirements of event detection and to layout the overall workflow (from sensing and event extraction methods to the operations and decision-supporting processes based on the extracted events) as an agenda for future event detection research. Guidance is presented on the current challenges to this research agenda, and future directions are discussed for conducting spatio temporal event detection in the era of big data, advanced sensing, and artificial intelligence.

A geospatial look at COVID-19 | Baka prioritizes connection | Geography report card


Susquehanna River
The Susquehanna River cuts through the folds of the Valley-and-Ridge province of the Appalachian Mountains in this photograph taken by the crew of the International Space Station. The Valley-and-Ridge province is a section of the larger Appalachian Mountain Belt between the Appalachian Plateau and the Blue Ridge physiographic provinces. The northeast-southwest trending ridges are composed of Early Paleozoic sedimentary rocks. The valleys between them were made of softer rocks (limestone and shales) that were more susceptible to erosion; they are now occupied by farms. The Susquehanna River cuts through several ridges as it flows south. The Susquehanna River flows 444 mi (714 kilometers) from upstate New York to Maryland, draining into Chesapeake Bay.

The “Nation’s Report Card” on Geography Reveals a World of Opportunities

Periodically since 1994, the National Assessment of Educational Progress (NAEP) has released its “report card” on geography education in America, providing a snapshot of student achievement. The most recent assessment was conducted in 2018 with a nationally representative sample of nearly 13,000 8th grade students.


Integration of Crowdsourced Images, USGS Networks, Remote Sensing, and a Model to Assess Flood Depth during Hurricane Florence

Hultquist, C., Cervone, G.
Remote Sensing
Crowdsourced environmental data have the potential to augment traditional data sources during disasters. Traditional sensor networks, satellite remote sensing imagery, and models are all faced with limitations in observational inputs, forecasts, and resolution. This study integrates flood depth derived from crowdsourced images with U.S. Geological Survey (USGS) ground-based observation networks, a remote sensing product, and a model during Hurricane Florence. The data sources are compared using cross-sections to assess flood depth in areas impacted by Hurricane Florence. Automated methods can be used for each source to classify flooded regions and fuse the dataset over common grids to identify areas of flooding. Crowdsourced data can play a major role when there are overlaps of sources that can be used for validation as well providing improved coverage and resolution.

Representation in geosocial data: grappling with uncertainty in digital traces of human activity

Hultquist, C.
International Journal of Humanities and Arts Computing
Researchers from the spatial humanities can play an active role in the ongoing discussion around representation and uncertainty in geosocial data. Opportunistic geosocial data from crowdsourced and user contributions are typically available in large quantities, however, these data are generally not sampled or collected with intentionality for research purposes. Therefore, digital traces from geolocationally-enabled devices may not provide data that are directly relevant to addressing precise questions or being used in applications of societal interest. It is crucial to first understand characteristics of geosocial data prior to proceeding with interpretation. The spatial humanities could encourage realization of the role data analysts and researchers play in creating narrative in light of large opportunistic data with many facets of uncertainty. An approach is proposed that suggests directions of inquiry into data limitations based on the characteristics of the source and the properties of the data. Finally, this article notes that the digital world influences the activities of individuals in real-life so the generalizability of the behaviour of users may be limited. Integrating other forms of relevant spatial data can help to bound uncertainty and constrain the interpretation of geosocial data.

Alum’s book on homelessness | Virus dashboards rely on GIS | Student maps marine traffic


Shown above is a partial view of Harrison Cole’s map, “Finding Refuge in Prince William Sound” published on visionscarto.net This map is a snapshot of marine traffic during the busiest months of 2017, which shows the paths of over 1,000 unique vessels and many thousands of trips. While minimizing damage to the environment is an important factor when considering a PPOR, the continued use of Prince William Sound as a high-volume thoroughfare both by oil tankers as well as other marine vessels means that damage to the environment will remain a matter of course rather than an exceptional tragedy.

How the Streets Got So Mean

When Don Mitchell was a master’s student in geography at Penn State in the late 1980s, he came across a newspaper article on homelessness that struck him. Homelessness was surging in many U.S. cities — from 1984 to 1987 the number of people living on the streets almost doubled — and the article attempted to explain the trend by looking into the characteristics of those experiencing homelessness: age, race, gender, work history, drug or alcohol abuse. That didn’t seem like a satisfactory approach to Mitchell.

The Software That’s Powering All the Coronavirus Dashboards

With roughly a zillion different sources out there for coronavirus information, experts and authorities are rapidly iterating on ways to best present useful information to the public. Are deaths spiking, or is the curve flattening? How is the virus moving around, and how can it be stymied? To collate all of this information, many groups are leaning on geographic information system (GIS) software. It’s often used by governments and large businesses that need to account for changes in the physical world, usually meaning disaster preparedness and mitigation, as well as monitoring public infrastructure, such as plotting the location of 911 calls.


Carbon isotope ratios in tree rings respond differently to climatic variations than tree-ring width in a mesic temperate forest

Agricultural and Forest Meteorology
Determining the response of forest growth and productivity to climate variability is crucial for understanding and modeling forest carbon sequestration in mesic temperate forests. Most tree-ring analyses have used monthly climate data. Daily climate data may be more appropriate to use in the determination of tree-ring response to climate because cell division, enlargement, and thickening occur during discrete periods of the growing season. We analyze annual tree-ring width and δ13C from Tsuga canadensis (1992–2012) at ten sites in the northeastern US to test the null hypothesis that tree-ring width and δ13C respond similarly to critical climate periods using daily climate data and linear regression. There was a significant difference in the climate response of ring width and δ13C. Precipitation predicted both δ13C and ring width with the highest r2 and greatest level of significance overall. δ13C integrated climate over longer periods of the year (and previous year) than ring width at most sites. δ13C showed a more consistent seasonal signal across sites for each climate variable than ring width. Our work provides a new perspective on the response of annual tree growth and δ13C to climatic variability that can inform ecosystem productivity, carbon cycle, and earth system models.

Virtual reality for student learning: Understanding individual differences

DOI: 10.37716/HBAB.2020010105
Virtual reality (VR) is emerging as a rapidly developing technology that holds significant promises to impact student learning. In this review, we focus on the features of this technology regarding levels of immersion and interaction and individual differences in cognitive characteristics of VR learners. We attempt to parse the specific technological features that enable effective learning and examine how students mentally process these features. While VR helps to create situated learning conditions, its theoretical significance lies in its ability to provide perception-action enabled experiences to the learner, and it is these experiences that lead to positive behavioural and brain outcomes compared to traditional methods of learning. Our discussion highlights the understanding of VR learning with respect to individual differences, especially in spatial abilities of the learner, and how variability in spatial abilities might impact both spatial learning and language learning.

Geography’s transition to remote learning | Last EarthTalks for spring semester | VR research roundup


poster detail

Zhuolai Pan, majoring in Earth sciences with a minor in geography and advised by Luke Trusel, won first place in the Undergraduate Exhibition Physical Sciences category for his presentation on “Dynamics of supraglacial lake drainage on Amery ice shelf, East Antarctica.” Abstract: Surface meltwater lakes can destabilize ice shelves through the process of hydrofracture, thereby reducing their buttressing effect and causing sea level to rise. Here, we present remotely sensed observations of repeated, rapid drainages of a ~4.3 km2 supraglacial lake on Amery ice shelf. We describe lake evolution and volume variations using ultra-high-resolution (~0.5 m) optical imagery and digital elevation models. Our research aims to advance the understanding of surface melt on ice shelf stability. A detail of his poster is shown.

Extended realities – How changing scale affects spatial learning

Investigating the relationship between the human body and its environment is essential to understand the process of acquiring spatial knowledge. However, few empirical evaluations have looked at how the visual accessibility of an environment affects spatial learning through direct experiences. To address this gap, this paper extends research on geographic scale (ground vs. pseudo-aerial perspectives) by incorporating active exploration in a human study. Results indicate that only low spatial ability participants benefit from the pseudo-aerial perspective in terms of spatial learning. In contrast, high spatial ability participants make more efficient use of the normal ground perspective.

Learning in the field: Comparison of desktop, immersive virtual reality, and actual field trips for place-based STEM education

Zhao, J., LaFemina, P. C., Carr, J., Sajjadi, P., Wallgrün, J. O., & Klippel, A.
2020 IEEE Conference on Virtual Reality and 3D User Interfaces (VR)
Field trips are a key component of learning in STEM disciplinessuch as geoscience to develop skills, integrate knowledge, and prepare students for lifelong learning. Given the reported success of technology-based learning and the prevalence of new forms oftechnology, especially with immersive virtual reality (iVR) entering the mainstream, virtual field trips (VFTs) are increasingly being considered as an effective form of teaching to either supplement or replace actual field trips (AFTs). However, little research has investigated the implications of VFTs in place-based STEM education, and empirical evidence is still limited about differences between students’ learning experiences and outcomes in VFTs experienced on desktop displays and field trips experienced in iVR. We report on a study that divided an introductory geoscience laboratory course into three groups with the first two groups experiencing a VFT either on desktop (dVFT) or in iVR (iVFT), while the third group went on an AFT. We compared subjective experiences (assessed via questionnaires) and objective learning outcomes for these groups. Our results suggest that, although students reported higher motivation and being more present in the iVFT group, they did not learn more compared to those in the dVFT group; both VFT groups yielded higher scores for learning experience and perceived learning outcomes than the actual field site visit. These findings demonstrate positive learning effects of VFTs relative to AFTs and provide evidence that geology VFTs need not be limited to iVR setups, which lead to considerable equipment costs and increased implementation complexity. Discussing the results, wereflect on the implications of our findings and point out future research directions.

CZ investigator: learning about critical zones through a VR serious game

Sajjadi, P., Bagher, M. M., Cui, Z., Myrrick, J., Swim, J. K., White, T. S., & Klippel, A.
2020 IEEE Conference on Virtual Reality and 3D User Interfaces Abstracts and Workshops (VRW) https://conferences.computer.org/vr-tvcg/2020/pdfs/
The critical zone (CZ) plays a pivotal role in the food-energy-water nexus, yet in its entirety, it is not well understood by society. Challenges range from imagining the invisible (from bedrock to soil) to understanding complex relations between the involved components. We have launched a transdisciplinary project driven by immersive technologies that allow for an extension of what physical reality offers society about the concept of CZ. We have developed a VR serious game that enables learners to have a concrete experience about what a CZ is, and how natural and human processes affect it.

Immersive place-based learning – An extended research framework

2020 IEEE Conference on Virtual Reality and 3D User Interfaces Abstracts and Workshops (VRW) https://conferences.computer.org/vr-tvcg/2020/pdfs/
At Kelvar 2019, we introduced a research framework for immersive virtual field trips (iVFTs) as a key element of immersive place-based learning. Organizing our research in this framework has been highly successful. We will be documenting outcomes of our research guided by this approach here, both as a conceptual extension of the original framework and through discussing three new studies that complement our existing empirical studies aimed at providing an evidence-based basis for assessing immersive learning. We believe in and strongly argue for the necessity of such a framework as we witness for the first time in the history of immersive technologies opportunities for comprehensive studies of immersive place-based learning, given the accessibility of the technology and the growing need for an evidence-based foundation. In detail, to assess the value of immersive experiences for learning, we argue for the necessity to compare them to traditional media such as desktop environments; correspondingly, we extended the framework to include non-sensing media. We conducted several new studies (both submitted and still unpublished work) that fill in gaps such as comparing desktop versus immersive VFTs, comparing Oculus GO versus Quest, and we describe our first experiences with moving immersive learning into the category of advanced iVFTs using both simulations and gamification as potential advantages of immersive technologies. We critically reflect on the results and lay out an agenda for future research on immersive place-based learning.

A Comparison of Visual Attention Guiding Approaches for 360°Image-Based VR Tours

Mechanisms for guiding a user’s visual attention to a particular point of interest play a crucial role in areas such as collaborative VR and AR, cinematic VR, and automated or live guided tour experiences in xR-based education. The attention guiding mechanism serves as a communication tool that helps users find entities currently not visible in their view, referenced for instance by another user or in some accompanying audio commentary. We report on a user study in which we compared three different visual guiding mechanisms (arrow, butterfly guide, and radar) in the context of 360°image-based educational VR tour applications of real-world sites. A fourth condition with no guidance tool available was added as a baseline. We investigate the question: How do the different approaches compare in terms of target finding performance and participants’ assessments of the experiences. While all three mechanisms were perceived as improvements over the no-guidance condition and resulted in significantly improved target finding times, the arrow mechanism stands out as the most generally accepted and favored approach, whereas the other two (butterfly guide and radar) received a more polarized assessment due to their specific strengths and drawbacks.

Book Review: Re-enchanting the World: Feminism and the Politics of the Commons

Jacklyn Weier
The AAG Review of Books
DOI: 10.1080/2325548X.2020.1722464
This edited collection by Italian feminist, scholar, and activist Silvia Federici features writings published in various venues over the course of her career. In essence, the collected writings trace the entanglement of capitalism, women’s reproductive work, the burgeoning debt crisis, and the commons. With a foreword by Peter Linebaugh, and publications from the 1980s to the present, Re-enchanting the World: Feminism and the Politics of the Commons offers a view of Federici’s previous work that argues for its continued importance and relevance in the world. Although Federici is most known for her book Caliban and the Witch: Women, the Body and Primitive Accumulation (Federici 2004), as well as her publications demonstrating the connections between sexuality and reproductive work, Re-enchanting the World offers a renewed perspective on some of the other key theories and ideologies Federici has delved into throughout her career. The inclusion and ordering of her previous publications successfully place her work among larger discussions concerning Marxist accumulation, the political importance of the commons, and the role of debt in capitalism and the creation of the proletariat.

Coming Out of the Foodshed: Phosphorus Cycles and the Many Scales of Local Food

Russell C. Hedberg II
Annals of the American Association of Geographers
DOI: 10.1080/24694452.2019.1630248
Systems of food production and provision face a set of complex and interdependent challenges to sustainably meet current and future nutrition needs and minimize the negative social and ecological consequences of modern agriculture. Food system localization, often in the context of specific initiatives like farmers’ markets, are frequently put forth as a promising strategy for establishing more just food systems and agroecological production that relies on regional resources and in situ ecological processes rather than agrichemical inputs. Despite a significant literature on local food, there remain critical omissions in geographic inquiry, particularly analyses of scale in regard to food system localization. This article uses scale as an analytical lens to examine phosphorus fertility on farms participating in a farmers’ market network in New York City. Through a synthesis of biogeochemical analysis, semistructured interviews, and nutrient network mapping, the work charts the complex and often contradictory interactions of material and discursive scales in local food systems. The lens of scale reveals multiple narratives of sustainability, indicating both the great potential for agroecological phosphorus management and significant structural problems that undermine the project of food system localization. These findings argue for a more expansive approach to localization that acknowledges a mosaic of overlapping scalar processes in food systems and that the sustainability promise of food system localization requires interconnected sustainabilities in multiple places and at multiple scales.

“The Care and Feeding of Power Structures”: Reconceptualizing Geospatial Intelligence through the Countermapping Efforts of the Student Nonviolent Coordinating Committee

Annals of the American Association of Geographers
DOI: 10.1080/24694452.2019.1631747
This article advances three interrelated arguments. First, by focusing on the Student Nonviolent Coordinating Committee’s (SNCC) Research Department, an undertheorized chapter in the civil rights movement, we advance an expressly spatialized understanding of the African American freedom struggle. Second, by focusing on an SNCC-produced pamphlet titled The Care and Feeding of Power Structures, we advance a larger historical geography of geospatial agency and countermapping of racial capital within black civil rights struggles. SNCC’s research praxis, which we argue constitutes a radical geospatial intelligence project, recognizes that geographical methods, information, and analytical insights are not just the purview of experts but are a set of political tools and processes deployed by a wide range of groups. Our article develops a deeper understanding of the rich spatial practices underlying black geographies and the role of geospatial intelligence in a democratic society outside the military–industrial–academic complex.

After searching databases including CINAHL and MEDLINE, we systematically reviewed 66 articles published between 2003 and 2019 and found four major gaps in racial/ethnic segregation and health disparities: (a) the concept of segregation was rarely operationalized at the neighborhood level, (b) except for the evenness and exposure dimension, other dimensions of segregation are overlooked, (c) little attention was paid to the segregation between whites and non‐black minorities, particularly Hispanics and Asians, and (d) mental health outcomes were largely absent. Future directions and opportunities include: First, other segregation dimensions should be explored. Second, the spatial scales for segregation measures should be clarified. Third, the theoretical frameworks for black and non‐black minorities should be tested. Fourth, mental health, substance use, and the use of mental health care should be examined. Fifth, the long‐term health effect of segregation has to be investigated, and finally, other competing explanations for why segregation matters at the neighborhood level should be answered.
