Boundaries And Policing: Space, Jurisdictions, And Roles In The Collection Of Official Crime Data, Cynthia Suzanne Barnett-Ryan Jan 2019

Boundaries And Policing: Space, Jurisdictions, And Roles In The Collection Of Official Crime Data, Cynthia Suzanne Barnett-Ryan

Graduate Theses, Dissertations, and Problem Reports (ETD)

The Uniform Crime Reporting (UCR) Program is a law enforcement statistical system open to unreported information due to its voluntary nature. As such, there need to be a valid and accepted means to estimate official reports of crime for those different levels of geography where reporting may be incomplete. Current methods of imputing and modeling UCR data, which have not been updated since the 1960s, are based upon conceptualizations of law enforcement agencies that may no longer be valid. These older models do not appropriately represent the law enforcement assessment of space and place and its effects on discretionary recording …

Criar Y Dejarse Criar: Trans-Situ Crop Conservation And Indigenous Landscape Management Through A Network Of Global Food Neighborhoods, Cass Madden

Capstone Collection

As climate change progresses, global food security is likely to become increasingly threatened and crop biodiversity will be a significant source of resiliency and adaptability. However, these adaptations will only be fully realized through cooperative in situ and ex situ conservation and cultivation of domesticated crops, crop wild relatives, and wild foods. This conservation is best realized in places where communities have the cultural resources to invest meaningfully in the cultivation of native crops, and where the cultivation of those crops can reinforce place-specific livelihoods and identities. To this end, the principal objective of this research is to propose a …


Crown-Level Mapping Of Tree Species And Health From Remote Sensing Of Rural And Urban Forests, Fang Fang Jan 2019

Crown-Level Mapping Of Tree Species And Health From Remote Sensing Of Rural And Urban Forests, Fang Fang

Graduate Theses, Dissertations, and Problem Reports (ETD)

Tree species composition and health are key attributes for rural and urban forest biodiversity, and ecosystem services preservation. Remote sensing has facilitated extraordinary advances in estimating and mapping tree species composition and health. Yet previous sensors and algorithms were largely unable to resolve individual tree crowns and discriminate tree species or health classes at this essential spatial scale due to the low image spectral and spatial resolution. However, current available very high spatial resolution (VHR) remote sensing data can begin to resolve individual tree crowns and measure their spectral and structural qualities with unprecedented precision. Moreover, various machine learning algorithms …

How Are Interannual Variations Of Land Surface Phenology In The Highland Pastures Of Kyrgyzstan Modulated By Terrain, Snow Cover Seasonality, And Climate Oscillations? An Investigation Using Multi-Source Remote Sensing Data, Monika Anna Tomaszewska

Electronic Theses and Dissertations

In the semiarid, continental climates of montane Central Asia, with its constant moisture deficit and low relative humidity, agropastoralism constitutes the foundation of the rural economy. In Kyrgyzstan, an impoverished, landlocked republic in Central Asia, herders of the highlands practice vertical transhumance—the annual movement of livestock to higher elevation pastures to take advantage of seasonally available forage resources. Dependency on pasture resource availability during the short mountain growing season makes herds and herders susceptible to changing weather and climate patterns. This dissertation focuses on using remote sensing observations over the highland pastures in Kyrgyzstan to address five interrelated topics: (i) …

The Archaeology Of The Postindustrial: Spatial Data Infrastructures For Studying The Past In The Present, Daniel Trepal Jan 2019

The Archaeology Of The Postindustrial: Spatial Data Infrastructures For Studying The Past In The Present, Daniel Trepal

Dissertations, Master's Theses and Master's Reports

Postindustrial urban landscapes are large-scale, complex manifestations of the past in the present in the form of industrial ruins and archaeological sites, decaying infrastructure, and adaptive reuse; ongoing processes of postindustrial redevelopment often conspire to conceal the toxic consequences of long-term industrial activity. Understanding these phenomena is an essential step in building a sustainable future; despite this, the study of the postindustrial is still new, and requires interdisciplinary connections that remain either unexplored or underexplored. Archaeologists have begun to turn their attention to the modern industrial era and beyond. This focus carries the potential to deliver new understandings of the …
