Diagnosing The Third World: The “Map Doctor” And The Spatialized Discourses Of Disease And Development In The Cold War, Timothy Barney

Rhetoric and Communication Studies Faculty Publications

In the early 1950s, the American Geographical Society, in collaboration with the United States Armed Forces and international pharmaceutical corporations, instituted a Medical Geography program whose main initiative was the Atlas of Disease, a map series that documented the global spread of various afflictions such as polio, malaria, even starvation. The Atlas of Disease, through the stewardship of its director, Jacques May, a French-American physician trained in colonial Hanoi, evidenced the ways in which cartography was rhetorically appropriated in the Cold War as a powerful visual discourse of development and modernization, wherein both the data content of the maps and …

Spatial Analysis Of Human-Induced Vegetation Productivity Decline Over Eastern Africa Using A Decade (2001-2011) Of Medium Resolution Modis Time-Series Data, Tobias Landmann, Olena Dubovyk

All Peer-Reviewed Publications

Climate variation and land transformations related to exploitative land uses are among the main drivers of vegetation productivity decline and ongoing land degradation in East Africa. We combined analysis of vegetation trends and cumulative rain use efficiency differences (CRD), calculated from 250-m MODISNDVI time-series data, to map vegetation productivity loss over eastern Africa between 2001 and 2011.The CRD index values were furthermore used to discern areas of particular severe vegetation productivity loss over the observation period. Monthly 25-km Tropical Rainfall Measuring Mission (TRMM) datametrics were used to mask areas of rainfall declines not related to human-induced land productivity loss. To …

Creative Heartland: Creative Capital And Knowledge Economy In Micropolitan Midwest, Philip A. Cavin

Dissertations and Theses @ UNI

Recent regional development studies increasingly focus on creative economies that provide an alternative perspective to regional development in a globalizing world-economy. However, most research in economic geography of creativity and innovation is exclusively concerned with larger metropolitan areas. The lack of attention does not make knowledge-based economy less relevant or creative capital less important in smaller urban regions, where it acts as an agent of economic development and revitalization. This study is the first attempt to use creative capital metrics and a combination of qualitative and qualitative analyses to investigate the creative capital and its economic implications in micropolitan areas …

Anthropogenics: Human Influence On Global And Genetic Homogenization Of Parasite Populations, Dante S. Zarlenga, Eric P. Hoberg, Benjamin Rosenthal, Simonetti Mattiucci, Giuseppe Nascetti

Harold W. Manter Laboratory of Parasitology: Faculty Publications

The distribution, abundance, and diversity of life on Earth have been greatly shaped by human activities. This includes the geographic expansion of parasites; however, measuring the extent to which humans have influenced the dissemination and population structure of parasites has been challenging. In-depth comparisons among parasite populations extending to landscape-level processes affecting disease emergence have remained elusive. New research methods have enhanced our capacity to discern human impact, where the tools of population genetics and molecular epidemiology have begun to shed light on our historical and ongoing influence. Only since the 1990s have parasitologists coupled morphological diagnosis, long considered the …

Numerical Simulation Of “An American Haboob”, A. Vukovic, M. Vujadinovic, G. Pejanovic, J. Andric, M. J. Kumjian, V. Djurdjevic, M. Dacic, Anup K. Prasad, Hesham El-Askary, B. C. Paris, S. Petkovic, W. Sprigg, S. Nickovic

Mathematics, Physics, and Computer Science Faculty Articles and Research

A dust storm of fearful proportions hit Phoenix in the early evening hours of 5 July 2011. This storm, an American haboob, was predicted hours in advance because numerical, land–atmosphere modeling, computing power and remote sensing of dust events have improved greatly over the past decade. High-resolution numerical models are required for accurate simulation of the small scales of the haboob process, with high velocity surface winds produced by strong convection and severe downbursts. Dust productive areas in this region consist mainly of agricultural fields, with soil surfaces disturbed by plowing and tracks of land in the high Sonoran Desert …

Brooklyn's Thirst, Long Island's Water: Consolidation, Local Control, And The Aquifir, Jeffrey A. Kroessler

Publications and Research

The creation of greater New York City in 1898 promised a solution to the problem of supplying Brooklyn and Queens with water. In the 1850s, the City of Brooklyn tapped ponds and streams on the south side of Queens County, and in the 1880s, dug wells for additional supply. This lowered the water table and caused problems for farmers and oystermen, many of whom sued the city for damages. Ultimately, salt water seeped into some wells from over-pumping. By 1896, Brooklyn’s system had reached its limit. Prevented by the state legislature from tapping the aquifer beneath Suffolk’s Pine Barrens, the …

Integrated Spatial Analysis Of Volunteered Geographic Information, Haydn Lawrence

Theses and Dissertations (Comprehensive)

Volunteered Geographic Information (VGI) is becoming a pervasive form of data within geographic academic research. VGI offers a relatively new form of data, one with both potential as a sensitive way to collect information about the world, and challenges associated with unknown and heterogeneous data quality. The lack of sampling control, variable expertise in data collection and handling, and limited control over data sources are significant research challenges. In this thesis, data quality of VGI is tackled as a general composite measure based on coverage of the dataset, the evenness in the density of data, and the relative evenness in …

Kingswood Lake Management Plan, Sarah Martina Tierney

Honors Theses and Capstones

High water quality and natural buffers exist on Kingswood Lake located in Brookfield, New Hampshire. A comprehensive lakes inventory (CSI) was recorded and health of the land, wildlife, and waterways were observed. Educational outreach was taken to inform the local community and to instruct them on proper stewardship of the land. A completed watershed management plan was constructed including key recommendation of limiting nitrogen loading in the area, checking septic systems for leaching, stabilizing shoreline from erosion, and establishing man-made rain gardens to help preserve water quality. The Kingswood watershed management plan acts as a guide for the town of …

Self-Reliance Beyond Neoliberalism: Rethinking Autonomy At The Edges Of Empire, Karen Hébert, Diana Mincyte

Publications and Research

Across scholarly and popular accounts, self-reliance is often interpreted as either the embodiment of individual entrepreneurialism, as celebrated by neoliberal designs, or the basis for communitarian localism, increasingly imagined as central to environmental and social sustainability. In both cases, self-reliance is framed as an antidote to the failures of larger state institutions or market economies. This paper offers a different framework for understanding self-reliance by linking insights drawn from agrarian studies to current debates on alternative economies. Through an examination of the social worlds of semisubsistence producers in peripheral zones in the Global North, we show how everyday forms of …

Dynamic Modeling Of Gnss Troposphere Wet Delay For Estimation Of Precipitable Water Vapour, Ahmed El-Mowafy, Johnny Lo

Research outputs 2014 to 2021

Proper dynamic modelling of the troposphere wet delay using the Global Navigation Satellite Systems (GNSS) measurements is important in precise point positioning and in estimation of the PrecipitableWater Vapour (PWV) for weather forecast. The random walk (RW) and the first-order Gauss-Markov (GM) autocorrelation models are commonly used for this purpose. However, it was found that these models consistently underestimate the temporal correlations that exist among the troposphere wet delay. Therefore, a new dynamic model is proposed. The performance of the proposed model in following the autocorrelation of actual data is demonstrated and its impact on the near-real time estimation of …

Crater Detection Via Genetic Search Methods To Reduce Image Features, Joseph Paul Cohen

Graduate Masters Theses

Recent approaches to crater detection have been inspired by face detection's use of gray-scale texture features. Using gray-scale texture features for supervised machine learning crater detection algorithms provides better classification of craters in planetary images than previous methods. When using Haar features it is typical to generate thousands of numerical values from each candidate crater image. This magnitude of image features to extract and consider can spell disaster when the application is an entire planetary surface. One solution is to reduce the number of features extracted and considered in order to increase accuracy as well as speed. Feature subset selection …

Producing Space: Block-By-Block Change In A Gentrifying Neighborhood, Jen Douglas

Graduate Doctoral Dissertations

Gentrification of urban neighborhoods is part of an ongoing restructuring of the city, linked to the emerging occupational structure of the service economy and the remaking of built environments that were created for a production economy. It is the name given to processes in which commodification and reinvestment accompany the in-migration of professional and managerial workers, often displacing prior residents and giving altered spatial form to inequality.

This dissertation is a case study of gentrification in Hyde and Jackson Squares, part of Boston's Jamaica Plain neighborhood. The emergence of gentrification pressures and their uneven distribution within the area is documented …

Studying Soil Moisture And Land-To-Water Carbon Export In Urbanized Coastal Areas Using Remotely Sensed Data And A Regional Hydro-Ecological Model, Yun Yang

Graduate Doctoral Dissertations

The main objective of this research was to study the flux of dissolved organic carbon (DOC) from a terrestrial urbanized watershed to an estuarine system using a process-based regional hydro-ecological model and remotely sensed data.

While DOC is an important component of the global carbon cycle, the link of the variations in terrestrial carbon storage is still poorly understood. Soil moisture is a key factor that influences the amount of available water for vegetation growth and the decomposition rate of organic matter in the soil and thus contributes to the amount of DOC in the soil at the land-water boundary. …

Wetlands Utilization And Rural Livelihood Diversification: A Case Of Simiyu Wetland, Magu, Tanzania, Emiliana Mwita

This paper explores the livelihood options provided by Simiyu wetland in Magu District, Simiyu Region, to the community living arround it using social survey methods. This paper is based on a study which shows that wetland farming is the main activity (75%) and significantly contribute to cash income generation, followed by livestock keeping, fishing and handicraft. …

Techniques For The Visualization Of Positional Geospatial Uncertainty, Brent A. Barré

LSU New Orleans Theses and Dissertations

Geospatial data almost always contains some amount of uncertainty due to inaccuracies in its acquisition and transformation. While the data is commonly visualized (e.g. on digital maps), there are unanswered needs for visualizing uncertainty along with it. Most research on effectively doing this addresses uncertainty in data values at geospatial positions, e.g. water depth, human population, or land-cover classification. Uncertainty in the data’s geospatial positions themselves (positional uncertainty) has not been previously focused on in this regard. In this thesis, techniques were created for visualizing positional uncertainty using World Vector Shoreline as an example dataset. The techniques consist of a …

Building A Gis Model To Assess Agritourism Potential, Brian G. Baskerville

Department of Geography: Dissertations, Theses, and Student Research

Rural areas of the world are developing and implementing tourism programs to diversify and reinvigorate their local economies. Often, these programs focus on privately-held lands in largely agricultural regions. In some countries, tourism development strategies have combined agriculture and tourism to create a new industry – agritourism. This industry, although not new in the United States, is still in its nascent stages. Before starting an agritourism enterprise, farmers and ranchers must consider the various factors that will likely influence their potential for long-term success. These factors can be grouped into 1) farm-specific factors such as an operator’s personality or the …

Reflections On Community Planning In San Francisco, Rachel Brahinsky, Miriam Chion, Lisa Feldstein

Politics

This paper builds on a dialogue between barrio planners and municipal planners on spatial and economic changes in San Francisco’s Mission District. The Mission is a predominantly Latino neighborhood with vibrant streets that have reflected and been transformed by the investments and displacement of recent decades. Though the Mission has seen tremendous upheaval with the influx of new capital and communities, this paper contends that efforts of community members shaped the development of the neighborhood with street-level planning expertise. We find that an attempt by community members to define their own development proposals and engage in land use decisions– rather …

Jewish Genetic Origins In The Context Of Past Historical And Anthropological Inquiries, John M. Efron

Human Biology Open Access Pre-Prints

The contemporary study of Jewish genetics has a long prehistory dating back to the eighteenth century. Prior to the era of genetics studies of the physical makeup of Jews were undertaken by comparative anatomists and physical anthropologists. In the nineteenth century the field was referred to as “race science.” Believed by many race scientists to be a homogeneous and pure race, Jews occupied a central position in the discourse of race science because they were seen as the control group par excellence to determine the relative primacy of nature or nurture in the development of racial characteristics. In the nineteenth …

Global Digital Elevation Model Accuracy Assessment In The Himalaya, Nepal, Luke G. Miles

Masters Theses & Specialist Projects

Digital Elevation Models (DEMs) are digital representations of surface topography or terrain. Collection of DEM data can be done directly through surveying and taking ground control point (GCP) data in the field or indirectly with remote sensing using a variety of techniques. The accuracies of DEM data can be problematic, especially in rugged terrain or when differing data acquisition techniques are combined. For the present study, ground data were taken in various protected areas in the mountainous regions of Nepal. Elevation, slope, and aspect were measured at nearly 2000 locations. These ground data were imported into a Geographic Information System …

From Generation To Generation: The Genetics Of Jewish Populations, Noah A. Rosenberg, Steven P. Weitzman

Human Biology Open Access Pre-Prints

Introduction:

This year marks the 35th anniversary of two noteworthy papers—one in this journal and the other in the American Journal of Human Genetics—posing the same famous question: are the different Jewish populations from around Europe, the Middle East, and North Africa more genetically similar to each other, or are they more similar to the local non-­‐Jewish populations in the regions where they were historically located? Both studies gathered blood-­‐group and protein variation data from a variety of Jewish and non-­‐Jewish populations, compiling significant “classical marker” data sets commensurate with the standard for human population-­‐ genetic studies at the time. …

Genetics And The Archaeology Of Ancient Israel, Aaron J. Brody, Roy J. King

Human Biology Open Access Pre-Prints

This paper is a call for DNA testing on ancient skeletal materials from the southern Levant to begin to database genetic information of the inhabitants of this crossroads region. Archaeologists and biblical historians view the earliest presence in the region of a group that called itself Israel in the Iron I period, traditionally dated to ca. 1200-1000 BCE. These were in villages in the varied hill countries of the region, contemporary with urban settlements in the coastal plains, inland valleys, and central Hill Country attributed to varied indigenous groups collectively called Canaanite. The remnants of Egyptian imperial presence in the …

Spatial Analysis Of Fatal Automobile Crashes In Nashville, Tn, 2001-2011, Yan Chen

Masters Theses & Specialist Projects

With increasing levels of motor vehicle ownership, automobile crashes have become a serious public issue in the U.S. and around the world. Knowing when, where, and how traffic accidents happen is critical in order to ensure road safety and to plan for adequate road infrastructure. There is a rich body of literature pertaining to time-related fatal crashes, most of which focuses on non-spatial factors such as a driver’s visibility at night, drinking and drug use, and road conditions. These studies provide a theoretical basis for understanding the causes of crashes from a non-spatial perspective, and a number of traffic laws …
