Humans As Sensors: The Influence Of Extreme Heat Vulnerability Factors On Risk Perceptions Across The Contiguous United States, Forrest Scott Schoessow Aug 2018

Humans As Sensors: The Influence Of Extreme Heat Vulnerability Factors On Risk Perceptions Across The Contiguous United States, Forrest Scott Schoessow

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Extreme heat events are the deadliest natural hazard in the United States and will continue to get worse in the coming years due to the effects of climate change. As a result, more people will experience deadly heat conditions. This highlights the need for decision-makers to develop better strategies for preventing future losses. How badly individuals are affected by extreme heat depends on many circumstances, such as how high temperatures actually are, weather conditions, and location. For example, a dry 90 °F day in Phoenix is probably more tolerable than a humid 90 °F day in New Orleans for most …


Estimation Of The Relationship Between Satellite-Derived Vegetation Indices And Live Fuel Moisture Towards Wildfire Risk In Southern California, Kristen Whitney, Seung Hee Kim, Shenyue Jia, Menas Kafatos Aug 2018

Estimation Of The Relationship Between Satellite-Derived Vegetation Indices And Live Fuel Moisture Towards Wildfire Risk In Southern California, Kristen Whitney, Seung Hee Kim, Shenyue Jia, Menas Kafatos

Mathematics, Physics, and Computer Science Faculty Articles and Research

Southern California possesses a Mediterranean climate having semi-arid to arid characteristics and contains shrubland areas at high risk to wildfire. To assess wildfire danger, fire agencies have been monitoring the moisture of vegetation, called live fuel moisture (LFM), using field-based sampling. Unfortunately, spatial and temporal resolution of live fuel moisture data are significantly limited because sampling is labor intensive. Remote sensing satellite data has been used to monitor vegetation moisture content and health of shrublands. Therefore, a potential approach to overcome the limitations of manual measurements of live fuel moisture is to use vegetation indices (VIs) derived from satellite data. …


The Energy Yield Of Global Crops 1961-2016, Quinn Montana Aug 2018

The Energy Yield Of Global Crops 1961-2016, Quinn Montana

Graduate Theses and Dissertations

It is often suggested that world food production must increase by 70%-100% or more by the year 2050 if we are to feed the anticipated world population at that time. To evaluate this claim, global crop production from 1961 to 2016 was inventoried using publicly available data from the United Nations Food and Agriculture Organization (FAO). To determine the adequacy of global crop output for humanity, annual global food crop production data (T y-1) were converted to energy yield in kilojoules (KJ y-1). These data were then compared to the annual metabolic energy requirement of the global human population. The …


The Impact Of World War One On The Forests And Soils Of Europe, Drew Heiderscheidt Jul 2018

The Impact Of World War One On The Forests And Soils Of Europe, Drew Heiderscheidt

Ursidae: The Undergraduate Research Journal at the University of Northern Colorado

The First World War was one of the deadliest conflicts in human history thus far. With the human toll being over eight million deaths, and millions more wounded, and as such it has taken hold in peoples imaginations for over a hundred years. However, one overlooked impact of the war is the environmental impact it had. The forests of Europe were significantly changed, going from being diverse ecosystems pre-war to monocultures after the war, dominated by single species of trees. The soil was also affected, more heavily in some places, becoming contaminated with heavy metals, as well as becoming entirely …


Transformation Of Post-Authoritarian Rural Development In Indonesia: A Study Of Farmer Breeder Community Development In West Bandung Regency, Rahmalia Rifandini Jul 2018

Transformation Of Post-Authoritarian Rural Development In Indonesia: A Study Of Farmer Breeder Community Development In West Bandung Regency, Rahmalia Rifandini

Masyarakat: Jurnal Sosiologi

The idea of post-authoritarian rural development is seen as the transformation of rural development since it no longer places the village as an object of development characterized by the demand for the preparation of rural development instruments. However, in practice, the development instruments do not result in the improvement of agricultural and livestock productivity as it happened in Kampung Pasir Angling, Suntenjaya Village, West Bandung Regency, West Java. Using a critical development perspective, the study argues that rural development transformation may apply if not limited to changes in public policy strategies, but rather to the social change in various sectors …

Re-Reading The Map Of Middle-Earth: Fan Cartography's Engagement With Tolkien's Legendarium, Stentor Danielson Jul 2018

Re-Reading The Map Of Middle-Earth: Fan Cartography's Engagement With Tolkien's Legendarium, Stentor Danielson

Journal of Tolkien Research

J.R.R. Tolkien provided an elaborate textual history for his writings about Middle-earth, but did not do so for his now-iconic maps. This paper examines how this difference, in concert with the general tendency of readers to treat maps as objective records of geography, has manifested in Tolkien's work and fan works based upon it. An examination of fan cartography shows a strong tendency to treat the published maps as records of geographical fact rather than historical documents from within Middle-earth.

Non-Gnss Smartphone Pedestrian Navigation Using Barometric Elevation And Digital Map-Matching, Daniel Broyles, Kyle J. Kauffman, John F. Raquet, Piotr Smagowski

Faculty Publications

Pedestrian navigation in outdoor environments where global navigation satellite systems (GNSS) are unavailable is a challenging problem. Existing technologies that have attempted to address this problemoften require external reference signals or specialized hardware, the extra size,weight, power, and cost of which are unsuitable for many applications. This article presents a real-time, self-contained outdoor navigation application that uses only the existing sensors on a smartphone in conjunction with a preloaded digital elevation map. The core algorithm implements a particle filter, which fuses sensor data with a stochastic pedestrian motion model to predict the user’s position. The smartphone’s barometric elevation is then …

Geography Faculty Publications and Presentations

A decline in dry season precipitation over tropical South America has a large impact on ecosystem health of the region. Results here indicate that the magnitude of negative trends in dry season precipitation in the past decades exceeds the estimated range of trends due to natural variability of the climate system defined in both the preindustrial climate and during the 850–1850 millennium. The observed drying is associated with an increase in vapor pressure deficit. The univariate detection analysis shows that greenhouse gas (GHG) forcing has a systematic influence in negative 30-year trends of precipitation ending in 1998 and later on. …
