Growth, Sprawl, And The Contradictions Of Capitalism: San Diego Suburbs And The Speculative Frenzy, 1970-1991, Richard Hogan
Purdue GIS Day
San Diego has become the most beautiful place where nobody can afford to live because speculative growth drives housing prices regardless of the level of supply or demand. How this happened in San Diego County is fairly clear. Marx explained that ground rents (and thereby land prices) increase when capital and labor are invested in the most valuable land and when investment is intensive, with vast amounts of labor and capital focused on the high yield properties to the virtual exclusion of less productive or less valuable lands. In fact, speculative growth between 1960 and 1980 conformed to what Marx …

Visualizing Election Results With Arcgis, Ryan Day
Purdue GIS Day
In 2018, Porter County, Indiana held its municipal elections concurrent with the national midterm elections. Using ArcGIS, the election results for the fourway race for the Duneland School Board at-large seat are mapped. These results are compared to other area election results, voter characteristics, and previous election results to try to visualize the correlation between factors affecting the race, including candidate ideology, geographic base, area demographics, turnout, and national electoral trends. This project serves as a demonstration of how GIS software can improve the understanding of what influences voters and election outcomes.

Investigation Of Late Roman Settlement On Dana Island, Bogsak Archaelogical Survey Project, Nicholas K. Rauh, Ayman Habib, Evan Flatt, Angus Moore, Gunder Varinlioglu
Purdue GIS Day
Purdue researchers participated in the 2019 season of the Bogsak Archaeological Survey Project in south coastal Turkey. Prof. Ayman Habib and Evan Flatt of CE used a drone to conduct LIDAR and camera mapping of the Late Roman harbor remains of Dana Island (approximately 250-800 AD). The remains, including vast quarry trenches and terraces of houses, cisterns, and churches, are covered in dense, nearly impenetrable garrigue brush, making standard architectural mapping laborious, inaccurate, and hazardous. The results of the LIDAR mapping should reveal a detailed map of obscured remains in real world coordinates, making it possible to map the remains …

A new 30-m spatial resolution global shoreline vector (GSV) was developed from annual composites of 2014 Landsat satellite imagery. The semi-automated classification of the imagery was accomplished by manual selection of training points representing water and non-water classes along the entire global coastline. Polygon topology was applied to the GSV, resulting in a new characterisation of the number and size of global islands. Three size classes of islands were mapped: continental mainlands (5), islands greater than 1 km2 (21,818), and islands smaller than 1 km2 (318,868). The GSV represents the shore zone land and water interface boundary, and …

Beyond Europeanization: The Politics Of Scale And Positionality In Lithuania’S Alternative Food Networks, Renata Blumberg, Diana Mincyte
Publications and Research
This article brings geographical insights to understanding the Europeanization of agri-food politics in new European Union member states. Most literature on agri-food policy and law in the European Union has conceptualized policy making and implementation as an institutional process involving multiple levels of governance. In this perspective, Europeanization is understood as a process through which stakeholders formulate, negotiate, and implement legal principles and procedures across various institutions at different levels of governance. By employing the conceptual tools developed in geographical research, we contribute a spatial and historical dimension to these studies. Our analysis shows how the politics of scale and …

The Paradox Of Urban Greening: Does It Harm The Very People Who Need It The Most?, Juliana Maantay
Sustainability Seminar Series
Urban greening and sustainability approaches are well accepted methods for improving the urban environment and combating the climate crisis. Cleaning up potentially contaminated lands and bringing them back into constructive public use is one of the benefits of greening. However, greening efforts may have unintended consequences, resulting in adverse social and economic impacts to the existing residents, who are often the most vulnerable urban populations. Spatial analyses of case study examples show that greening can spur “green gentrification.” Measures can be taken to integrate social equity objectives into urban sustainability planning, to mitigate gentrification, and to improve equitable distribution of …

Relationships Between Soil Macroinvertebrates And Nonnative Feral Pigs (Sus Scrofa) In Hawaiian Tropical Montane Wet Forests, Nathaniel H. Wehr, Creighton M. Litton, Noa K. Lincoln, Steven C. Hess
United States National Park Service: Publications
Abstract Nonnative feral pigs (Sus scrofa) are recognized throughout the New World as a highly significant introduced species in terms of ecosystem alteration. Similarly, nonnative soil macroinvertebrates (e.g. earthworms, ground beetles) invade and alter the structure and function of native habitats globally. However, the relationship between feral pigs and soil macroinvertebrates remains largely unknown. This study analyzed relationships between these taxa using nine sites located inside and outside of feral pig management units representing a * 25 year chronosequence of removal in tropical montane wet forests in Hawai‘i. Soil macroinvertebrates were sampled from plots categorized as: actively trampled by feral …

Hutterite Colonies And The Cultural Landscape: An Inventory Of Selected Site Characteristics, Simon Evans
Journal of Amish and Plain Anabaptist Studies
Hutterite colonies are a growing and sustainable element in the cultural landscape of the Canadian Prairies and Northern Great Plains of the United States. Their increasing numbers do something to offset the disappearance of the smallest service centers on the plains. While the diffusion of these communities has been well documented, the morphology of the settlements has been less well studied. New technology makes it possible to remotely evaluate selected characteristics of almost all Hutterite colonies. This paper describes the differences, with respect to orientation, layout and housing types, both between the four clan groups and within the Dariusleut and …

The Growth Of Amish And Plain Anabaptist Communities In Kentucky, Joseph Donnermeyer, Cory Anderson
Journal of Amish and Plain Anabaptist Studies
This article examines the growth of Amish and plain Anabaptist communities and population in Kentucky, one of the few southern states with a sizeable plain Anabaptist presence across much of its rural areas. Within the Amish religious tradition, this study focuses on both the broadly defined Old Order Amish, namely, those who prohibit ownership of motor vehicles for transportation, and the Amish-Mennonites, those who allow ownership. We provide an overview of their community formation and present a county-based estimate of their population. There are now 53 Amish communities in Kentucky, and a population of nearly 10,000. Over half (27) of …

Church District Fissioning And Watershed Boundaries Among Holmes County, Ohio, Amish, Scott Long, Richard Moore
Journal of Amish and Plain Anabaptist Studies
Upon reaching 40 households, an Amish church district typically divides into two smaller, relatively equally sized districts. This article analyzes the relationship between Amish church divisions and topographic demarcation lines within Clark Township, Holmes County, Ohio, from 1930 to 2010. In findings, divisions often follow physical geography boundaries, such as ridges that outline the edge of a watershed, or rivers and streams that essentially define topography within a watershed. Further, Amish leaders divide churches with objectives based on several socioreligious factors, from the maintenance of the faith community to the goal of preserving Amish neighborhoods and rural identity, while also …

Where Are The Plain Anabaptists?, Cory Anderson, Joseph Donnermeyer
Journal of Amish and Plain Anabaptist Studies
This article discusses geographic analytical units of plain Anabaptist groups relevant for conceptualizing spatial dispersion across Canada and the United States. All plain Anabaptist groups are tied to the land, hence, the religious values, cultural traditions, and social organizations of plain Anabaptists are intimately and reciprocally bound up with geography. We discuss six geographic units of the plain Anabaptists and describe how we gathered information about their locations. These include: local church, local affiliation, settlement, region, broad affiliation, and global region. We present maps of their geographic distribution throughout Canada and the U.S., noting spatial patterns. Hence, this article provides …
