Planning For Student Initiative: Creating A Digital Textbook, Ronald Vaughan Morris

The Councilor: A National Journal of the Social Studies

Undergraduate students enrolled in a university class created an elementary social studies book delivered to computers, personal communication devices, and tablets. Students worked in an interdisciplinary team to create the interactive platform. The students worked with both university and community partners to create the text. The study presented described both the content and the process of student generation of material followed by community member review, and the revision cycle used by the students to create features and components of the text materials. A variety of false starts and marketing challenges reflect the obstacles undergraduate students face when creating marketable products …

Juxtaposing Primary- And Intermediate-Elementary Trade Books’ Historical Representation Of Amelia Earhart, Rachael A. Burkhardt

The Councilor: A National Journal of the Social Studies

Amelia Earhart can be used in the classroom not only to interest students but can also be used to cover Common Core State Standards (CCSS), National Council for the Social Studies (NCSS) framework, and Next Generation Science Standards (NGSS). When teaching Amelia Earhart, textbooks, trade books, and primary sources can be used, however one must be careful with the misrepresentations each resource can portray. To look at what is misrepresented, omitted, and included within primary and intermediate grade level trade books, 32 books were scrutinized. The trade books being analyzed were found to have some historically representative and misrepresentative elements …

Wise-Practice Use Of Visual Primary Sources: Towards A More Interactive Presentation Of Content, Lamont E. Maddox, James B. Howell, Cory Callahan

The Councilor: A National Journal of the Social Studies

Modern citizens are often confronted by visual social media seeking to persuade or influence their opinion on public issues. In order for students to develop civic competence, they must be able to evaluate visual data. An interactive slide lecture using four to five strategically-chosen visuals holds promise for developing students’ interpretive skills, but this strategy can be difficult to implement. In this article, we share a collaboratively designed educative primer or teacher scaffold created in response to the challenges experienced by “Amelia” as she implemented an interactive slide lecture with 7^th grade students. Our intent in sharing the primer …

Agricultural Permanence In Large Asian Cities: A Case Study Of Nanjing, China, Gregory Veeck, Charles Emerson, Erik S. Breidinger

Faculty Research and Creative Activities Award (FRACAA)

Nanjing, the capital of China's Jiangsu Province, has grown rapidly during the post-reform era and the pace of change placed tremendous pressure on the city's arable land resources. This case study of land use/land cover change (LUC) in Nanjing's Jiangning district assesses changes in agricultural land, production, and labor within the ten 2016-era jiedao (sub-district political units) of Jiangning from 2000 to 2015. This case study provides an opportunity to assess an important component of the Ginsburg-McGee desakota hypothesis that predicts that Asian extended metropolis regions, unlike similar large cities in Western nations, will consistently maintain agricultural land and labor …

Acoustically Advertising Male Harbour Seals In Southeast Alaska Do Not Make Biologically Relevant Acoustic Adjustments In The Presence Of Vessel Noise, Leanna P. Matthews, Michelle E.H. Fournet, Christine Gabriele, Holger Klinck, Susan E. Parks

United States National Park Service: Publications

Aquatically breeding harbour seal (Phoca vitulina) males use underwater vocalizations during the breeding season to establish underwater territories, defend territories against intruder males, and possibly to attract females. Vessel noise overlaps in frequency with these vocalizations and could negatively impact breeding success by limiting communication space. In this study, we investigated whether harbour seals employed anti-masking strategies to maintain communication in the presence of vessel noise in Glacier Bay National Park and Preserve, Alaska. Harbour seals in this location did not sufficiently adjust source levels or acoustic parameters of vocalizations to compensate for acoustic masking. Instead, for every 1 dB …

Remote Sensing Derived Indices For Tracking Urban Land Surface Change In Case Of Earthquake Recovery, Sahar Derakhshan, Susan Lynn Cutter, Cuizhen Wang

Faculty Publications

The study of post-disaster recovery requires an understanding of the reconstruction process and growth trend of the impacted regions. In case of earthquakes, while remote sensing has been applied for response and damage assessment, its application has not been investigated thoroughly for monitoring the recovery dynamics in spatially and temporally explicit dimensions. The need and necessity for tracking the change in the built-environment through time is essential for post-disaster recovery modeling, and remote sensing is particularly useful for obtaining this information when other sources of data are scarce or unavailable. Additionally, the longitudinal study of repeated observations over time in …

Comparing Individual Perceptions Of Food Desert With Quantitative Measures In Omaha, Nebraska., Hector N. Samani, Bradley Bereitschaft

UNO Student Research and Creative Activity Fair

Food deserts have been linked to an increase in chronic diseases such as obesity and diabetes, due to lower access to affordable and healthy foods. The United States Department of Agriculture (USDA) outlines various methods and variables for defining food deserts, in attempts to standardize what constitutes a food desert or their characteristics. The USDA identifies the state of Nebraska as having both rural and urban food deserts, with an increase of food insecurity from 1.1% – 3.0% between 2007 and 2012 and warns of further increase of food deserts and its impact if measures are not taken. However, there …

Carnivore Population Structure Across An Urbanization Gradient: A Regional Genetic Analysis Of Bobcats In Southern California, Julia G. Smith, Megan K. Jennings, Erin E. Boydston, Kevin R. Crooks, Holly B. Ernest, Seth Riley, Laurel E. K. Serleys, Shaelynn Sleater-Squires, Rebecca L. Lewison

United States National Park Service: Publications

Context In human-dominated landscapes, habitat fragmentation and barriers to movement can interrupt gene flow. While often considered at a local extent, regional analyses are also needed to reveal broader landscape-mediated population processes.

Objectives To explore the relationship between patterns of gene flow and fragmentation resulting from urbanization across southern California, we used the bobcat as an indicator species. We assembled data for a landscape level genetic analysis across southern California from both archived and new samples, including two northern Californian populations for comparison, to identify local and regional areas affected by isolation.

Methods Our regional analyses focused on a dataset …

Asynchronous Carbon Sink Saturation In African And Amazonian Tropical Forests, Wannes Hubau, Simon L. Lewis, Et. Al. Authors

United States National Park Service: Publications

Structurally intact tropical forests sequestered about half of the global terrestrial carbon uptake over the 1990s and early 2000s, removing about 15 percent of 1–3 anthropogenic carbon dioxide emissions. Climate-driven vegetation models 4,5 typically predict that this tropical forest ‘carbon sink’ will continue for decades . Here we assess trends in the carbon sink using 244 structurally intact African tropical forests spanning 11 countries, compare them with 321 published plots from Amazonia and investigate the underlying drivers of the trends. The carbon sink in live aboveground biomass in intact African tropical forests has been stable for the three decades to …

No.08: Improving The Profitability Of Wet Market Food Vendors In China, Xinxian Qi, Taiyang Zhong, Zhenzhong Si, Xianjin Huang

Hungry Cities Partnership

■ The characteristics of individual vendors and their business operations have a more significant impact on business profits than more general socioeconomic factors. Policy interventions need to prioritize the former.

■ The profits of wet market vendors vary spatially in Nanjing, China. The average profit level in central urban districts is higher than in peri-urban districts.

■ Almost all determinants have more significant impacts on vendor profitability in peri-urban than urban areas. Measures should therefore be taken to improve the profitability of wet market vendors in peri-urban areas.

No.09: Enhancing Food Security Through Urban Agriculture In Kingston, Jamaica, Elizabeth Thomas-Hope, Robert Kinlocke, Therese Ferguson

Hungry Cities Partnership

■ Much focus has been accorded rural agriculture, both in the literature and in practice. Yet urban agriculture is both a viable and necessary area of focus as it pertains to food security in Jamaica.

■ An education and communication strategy is required to ensure that attitudes towards nutrition and poor food choices are changed (within the range of affordability) in efforts to achieve food security.

■ Given the threats posed by climate change, the development of urban agriculture should incorporate not only previously designated sites through zoning for small-scale livestock and produce rearing; it also should incorporate backyard farming/gardening, …

No.06: Gender Inequality And Food Security Policy Responses, Mary Caesar

Hungry Cities Partnership

■ Gender inequality and the legacy of racial discrimination operate alongside poverty and economic inequality to shape the household food security experience in low-income areas in South African cities.

■ In Cape Town, male-headed households are more likely to be food secure than female-headed households, although both experience high levels of severe food insecurity.

■ National food security policy and local government do not recognize the systemic nature of gender inequality and food insecurity; a gap that needs to be addressed.

Problematic Plant Monitoring In Homestead National Monument Of America, 2006–2017, Craig C. Young

United States National Park Service: Publications

Abstract

Managers are challenged with the impact of problematic plants, including exotic, invasive, and pest plant species. Information on the abundance, distribution, and location of these plants is essential for developing risk-based approaches to managing these species. Based on surveys conducted in 2006, 2009, 2013, and 2017, Heartland Inventory and Monitoring Network staff and contractors identified a cumulative total of 20 potentially problematic plant species in Homestead National Monument of America (NMA). Of the 13 species found in 2017, we characterized 4 as very low frequency, 4 as low frequency, 2 as medium frequency, and 3 as high frequency. Only …

Legal Geographies And Political Ecologies Of Water Allocation In Maui, Hawai'i, Alida Cantor, Kelly Kay, Chris Knudson

Geography Faculty Publications and Presentations

Throughout the Hawaiian Islands, sugar plantations have controlled a large proportion of water resources for over a century, often leaving little water in streams to support ecosystems or Native Hawaiian cultural and agricultural practices. Recently, in Maui, Hawai‘i, community activists and lawyers representing Native Hawaiian and environmental interests have successfully reclaimed water resources for instream flow utilizing legal processes and tools such as Hawai‘i’s public trust doctrine, which has plural roots in both Hawaiian and Western legal traditions. In this paper, we use qualitative fieldwork, including interviews, participant observation, and archival data collection, to explore two recent and ongoing legal …

Mult-Spectral Imaging Of Vegetation With A Diffractive Plenoptic Camera, Tristan R. Naranjo

Theses and Dissertations

Snapshot multi-spectral sensors allow for object detection based on its spectrum for remote sensing applications in air or space. By making these types of sensors more compact and lightweight, it allows drones to dwell longer on targets or the reduction of transport costs for satellites. To address this need, I designed and built a diffractive plenoptic camera (DPC) which utilized a Fresnel zone plate and a light field camera in order to detect vegetation via a normalized difference vegetation index (NDVI). This thesis derives design equations by relating DPC system parameters to its expected performance and evaluates its multi-spectral performance. …

North Atlantic Hurricane Winds In Warmer Than Normal Seas, Jill C. Trepanier

Faculty Publications

Tropical cyclones devastate coastlines around the world. The United States and surrounding areas experienced catastrophic extreme events in recent hurricane seasons. Understanding extreme hurricanes and how they change in a warming ocean environment is of the utmost importance. This study makes use of the historical, positive relationship between average summer sea surface temperatures (SSTs) and maximum hurricane wind speeds across the North Atlantic Basin from 1854-2018. Geographically weighted regression shows how the relationship between hurricane winds and SSTs varies across space. Each localized slope is used to increase historical wind speeds to represent winds in a three-degree Celsius warmer-than-average sea …

Climatology And Spatiotemporal Analysis Of North Atlantic Rapidly Intensifying Hurricanes (1851-2017), Kathleen M. Benedetto, Jill C. Trepanier

Faculty Publications

In recent decades, the scientific ability to project tropical cyclone (TC) intensities and tracks has improved. Hurricanes undergoing the process of rapid intensification (RI) have created new barriers in formulating predictions of TC paths and peak velocities. Current research suggests the warming climate may produce more intense TCs with a higher probability of undergoing RI during their life cycle. The increased likelihood of rapidly intensifying TCs necessitates the development of an RI climatology spanning the current North Atlantic record. A time series count analysis suggests a significant increasing trend of RI events in the Atlantic basin by 29.1% (17%-45%) from …

Trend Analysis Of Multiple Extreme Hourly Precipitation Time Series In The Southeastern United States, Vincent M. Brown, Barry D. Keim, Alan W. Black

Faculty Publications

Annual trends in extreme hourly precipitation time series were examined at 50 first-order weather stations across the southeastern United States from 1960 to 2017. Results indicated that the magnitude of annual maximum 1-, 3-, 6-, 12-, and 18-h periods did not broadly change at the sites analyzed; however, the numerical value that defines a (station specific) 90th-percentile hourly accumulation significantly (p ≤ 0.05) increased at 36% (18/50) of the stations. No station had a significant decreasing trend in annual 90th-percentile hourly event magnitude. Stations in Texas observed the largest increase in annual 90th-percentile hourly event magnitude, where parameter estimates showed …
