Introduction To Gis Using Open Source Software, 4th Ed, Frank Donnelly

Open Educational Resources

This tutorial was created to accompany the GIS Practicum, a day-long workshop offered by the Newman Library at Baruch College CUNY that introduces participants to geographic information systems (GIS) using the open source software QGIS. The practicum introduces GIS as a concept for envisioning information and as a tool for conducting geographic analyses and creating maps. Participants learn how to navigate a GIS interface, how to prepare layers and conduct a basic geographic analysis, and how to create thematic maps. This tutorial was written using QGIS version 1.8 "Lisboa", a cross-platform (Windows, Mac, Linux) desktop GIS software package.

Remote Sensing Of Soil Moisture In Vineyards Using Airborne And Ground-Based Thermal Inertia Data, Aiman Soliman, Richard J. Heck, Alexander Brenning, Ralph Brown, Stephen Miller

Publications and Research

Thermal remote sensing of soil moisture in vineyards is a challenge. The grass-covered soil, in addition to a standing grape canopy, create complex patterns of heating and cooling and increase the surface temperature variability between vine rows. In this study, we evaluate the strength of relationships between soil moisture, mechanical resistance and thermal inertia calculated from the drop of surface temperature during a clear sky night over a vineyard in the Niagara region. We utilized data from two sensors, an airborne thermal camera (height ≈ 500 m a.g.l.) and a handheld thermal gun (height ≈ 1 m a.g.l.), to explore …

The Role Of Suburbia In The Attribution Of Greenhouse Gas Emissions, Jochen Albrecht, Peter Marcotullio, Andrea Sarzynski, Niels Schulz

Publications and Research

The original goal of the research presented here was to quantify by world region, the contribution of urbanized areas to global greenhouse gas (GHG) emissions (EDGAR, 2011). Regressions on population density and growth rate, GDP, and heating/cooling degree days, as well as a row of other non-significant variables, show that the contribution of urban extents is between 38% and 49% of total emissions (Marcotullio et al., 2012). In spite of using very liberal definitions of urban extents (GRUMP, 2011) this is at the low end of academic estimates (Satterthwaite, 2008; WEO, 2008; Dhakal, 2010). It is no surprise that the …

The Intellectual And Curricular Spaces Of Knowledge Studies, Jay H. Bernstein

Publications and Research

The words “knowledge” and “information” are sometimes used interchangeably, but the connection between them is complex and problematic. Knowledge is a mental product gained from engaging with information. All educational subjects, scholarly disciplines, occupations, and activities produce knowledge as well as information. Because libraries encompass potentially all subjects, professional vision in librarianship would benefit from an examination of knowledge that transcends the methods and topical concerns of individual disciplines. An interdisciplinary (or transdisciplinary) framework in which to view knowledge was pioneered in the post-Sputnik age by Fritz Machlup and Michael Polanyi. Their insights have stimulated scholars to develop research, publications, …

Impacts Of Soil-Acquifer Heat And Water Fluxes On Simulated Global Climate, Nir Krakauer, M. J. Puma, B. I. Cook

Publications and Research

Climate models have traditionally only represented heat and water fluxes within relatively shallow soil layers, but there is increasing interest in the possible role of heat and water exchanges with the deeper subsurface. Here, we integrate an idealized 50m deep aquifer into the land surface module of the GISS ModelE general circulation model to test the influence of aquifer-soil moisture and heat exchanges on climate variables. We evaluate the impact on the modeled climate of aquifer-soil heat and water fluxes separately, as well as in combination. The addition of the aquifer to ModelE has limited impact on annual-mean climate, with …

Habitat And Host Indicate Lineage Identity In Colletotrichum Gloeosporioides S.L. From Wild And Agricultural Landscapes In North America, Vinson P. Doyle, Peter V. Oudemans, Stephen A. Rehner, Amy Litt

Publications and Research

Understanding the factors that drive the evolution of pathogenic fungi is central to revealing the mechanisms of virulence and host preference, as well as developing effective disease control measures. Prerequisite to these pursuits is the accurate delimitation of species boundaries. Colletotrichum gloeosporioides s.l. is a species complex of plant pathogens and endophytic fungi for which reliable species recognition has only recently become possible through a multi-locus phylogenetic approach. By adopting an intensive regional sampling strategy encompassing multiple hosts within and beyond agricultural zones associated with cranberry (Vaccinium macrocarpon Aiton), we have integrated North America strains of Colletotrichum gloeosporioides s.l. from …

Refining Environmental Satellite Data Using A Statistical Approach, Md Zahidur Rahman, Leonid Roytman, Abdelhamid Kadik

Publications and Research

The proposed approach in this article applies an efficient and novel statistical technique to accurately describe radiometric data measured by Advanced Very High Resolution Radiometers (AVHRR) onboard the National Oceanic and Atmospheric Administration’s (NOAA) Polar Orbiting Environmental Satellites (POES). The corrected data set will then be applied to improve the strength of NOAA Global Vegetation Index (GVI) data set for the 1982- 2003 period produced from AVHRR. The GVI is used extensively for studying and monitoring land surface, atmosphere and recently for analyzing climate and environmental changes. The POES AVHRR data, though useful, cannot be directly used in climate change …

The Battle Of Brooklyn: World City And Space Of Neighborhoods., Benjamin C. Shepard

Publications and Research

Throughout Brooklyn, regular people are fighting off the negative dynamics of urban experience, including uneven development, speculative gentrification, displacement, and police brutality long seen in global cities. Yet, little of the global cities literature considers the ways local actors impact global forces shaping world cities. Instead, observers of globalization suggest local actors have been relegated the sidelines as passive spectators of larger social and economic forces. Many wonder, is there a space for agency in global cities? Can regular people shape the dynamics of life in cities? For many, the answer is clearly affirmative. Throughout the borough of Brooklyn, people …

The Impact Of Demographics On 21st Century Education, Norman Eng

Global Futures And Government Towns: Phosphates And The Production Of Western Sahara As A Space Of Contention, Mark Drury

Publications and Research

The study of natural resources lends itself to theorizing the politics of nature and the politics of time. The space of Western Sahara, where both remain highly contested, provides an opportunity to consider the ramifications of resources in political conflict at different historical moments. Drawing from environmental histories of North Africa and the Sahara, as well as the anthropology of time, the author focuses on two historical moments. The first, from 1945 to 1972, concerns the discovery of phosphate deposits during the Spanish colonial period and the implications of this discovery for political authority in the Sahara more broadly. The …

The Impact Of Gut Passage By Binturongs (Arctictus Binturong) On Seed Germination, Christina P. Colon, Ahimsa Campos-Arceiz

Publications and Research

Binturongs (Arctictis binturong) are the largest of Asian civets and, due to their highly frugivorous diet, are expected to play an important role in seed dispersal processes. To study the effect of binturong gut passage on seed viability, we fed 10 captive binturongs with fruits of longan (Dimocarpus longan), papaya (Carica papaya) and chiku (Manilkara zapota), collected the seeds they defaecated, and planted these to determine seed germination rate and time. Of the defaecated seeds, 90.4% passed through binturong gut intact in under nine hours, and 99.4% passed in under 33 hours. Chiku seeds had the highest germination rate (35.7% …

Allometric Scaling And Resource Limitations Model Of Tree Heights: Part 1. Model Optimization And Testing Over Continental Usa, Yuli Shi, Sungho Choi, Xiliang Ni, Sangram Ganguly, Gong Zhang, Hieu V. Duong, Michael A. Lefsky, Marc Simard, Sassan S. Saatchi, Shihyan Lee, Wenge Ni-Meister, Shilong Piao, Chunxiang Cao, Ramakrishna R. Nemani, Ranga B. Myneni

Publications and Research

A methodology to generate spatially continuous fields of tree heights with an optimized Allometric Scaling and Resource Limitations (ASRL) model is reported in this first of a multi-part series of articles. Model optimization is performed with the Geoscience Laser Altimeter System (GLAS) waveform data. This methodology is demonstrated by mapping tree heights over forested lands in the continental USA (CONUS) at 1 km spatial resolution. The study area is divided into 841 eco-climatic zones based on three forest types, annual total precipitation classes (30 mm intervals) and annual average temperature classes (2 °C intervals). Three model parameters (area of single …

Lefsky, Marc Simard, Sassan S. Saatchi, Shihyan Lee, Wenge Ni-Meister, Shilong Piao, Chunxiang Cao, Ramakrishna R. Nemani, Ranga B. Myneni

Publications and Research

The ultimate goal of this multi-article series is to develop a methodology to generate continuous fields of tree height and biomass. The first paper demonstrated the need for Allometric Scaling and Resource Limitation (ASRL) model optimization and its ability to generate spatially continuous fields of tree heights over the continental USA at coarse (1 km) spatial resolution. The objective of this second paper is to provide an assessment of that approach at site scale, specifically at 12 FLUXNET sites where more accurate data are available. Estimates of tree heights from the Geoscience Laser Altimeter System (GLAS) waveform data are used …

Particularizing Universal Education In Postcolonial Sierra Leone, Grace Pai

Publications and Research

This paper presents a vertical case study of the history of universalizing education in postcolonial Sierra Leone from the early 1950s to 1990 to highlight how there has never been a universal conception of universal education. In order to unite a nation behind a universal ideal of schooling, education needed to be adapted to different subpopulations, as the Bunumbu Project did for rural Sierra Leoneans in the 1970s to 1980s. While the idea of “localizing” education was sound, early program success was undermined by a lack of clarity behind terms like “rural” or “community.” This was exacerbated by a change …

Mydigitalfootprint.Org: Young People And The Proprietary Ecology Of Everyday Data, Gregory Thomas Donovan

All Open Access Legacy Dissertations and Capstone Projects

Young people are the canaries in our contemporary data mine. They are at the forefront of complex negotiations over privacy, property, and security in environments saturated with information systems. The productive and entertaining promises of proprietary media have led to widespread adoption among youth whose daily activities now generate troves of data that are mined for governance and profit. As they text, email, network, and search within these proprietary ecologies, young people's identity configurations link up with modes of capitalist production. The MyDigitalFootprint.ORG Project was thus initiated to unpack and engage young people's material social relations with/in proprietary ecologies through …

The Digital Diaspora In Sunset Park: Information And Communication Technologies In Brooklyn’S Chinatown, Sarah Wendolyn Williams

Dissertations, Theses, and Capstone Projects

My thesis is that, contrary to expectations that working-class Chinese immigrants would have less access to information and communication technologies (ICTs) and fewer skills in using them, struggling immigrants to Brooklyn's Chinatown are skilled at using ICTs and do so on a daily basis, in ways that enrich their relationships and transnational participation. They are able to do this despite the severe limitations that ethnic enclave employment places on their time and opportunities, in part because of heavy use of affordable internet cafes in the neighborhood. Building on a growing body of literature on new media and diaspora, this thesis …

Producing Bodies, Knowledge, And Community In Everyday Civilian Struggle Over Surveillance, Michelle C. Billies

Dissertations, Theses, and Capstone Projects

In a global context of rapidly expanding security practices, those cast as social threats are themselves often most risk of harm. In this dissertation, I develop the concept surveillance threat (ST) to describe the perception or experience of impending or actual harm faced by targeted civilians when they are stopped or screened by law enforcement. Singled out by race and other lines of sociocultural force, those stopped risk physical, legal, sexual, and spatial consequences. Yet focusing solely on the risk of harm limits the full meaning of this encounter. As I show in my research, civilians persistently struggle against these …

The Rise Of Disyllables In Old Chinese: The Role Of Lianmian Words, Jian Li

Dissertations, Theses, and Capstone Projects

The history of Chinese language is characterized by a clear shift from monosyllabic to disyllabic words (Wang 1980). This dissertation aims to provide a new diachronic explanation for the rise of disyllables in the history of Chinese and to demonstrate its significance for Modern Chinese prosody and lexicalization.

A corpus of 300 Lianmian words in Old Chinese was compiled, including 96 Shuāngshēng words, 172 Diéyùn words and 32 Splitting-sound words. This study builds on previous morphological and phonological research on disyllables in Chinese and looks closely at detailed aspects of Old Chinese sound patterns and their evolution. Based on the …

Understanding A Pest: Phylogeography And Systematics Of The Plum Curculio (Conotrachelus Nenuphar), Samuel N. Crane

Dissertations, Theses, and Capstone Projects

The plum curculio (Conotrachelus nenuphar Herbst) (Coleoptera: Curculionidae) is an economically and ecologically important pest in North America but is understudied despite having a long history in the scientific literature. Its chemical ecology, life history habits, and distribution are all well characterized. However, there is a dearth of knowledge concerning the population structure and evolutionary history of the species. This study aims to use methods from evolutionary biology to better understand an agricultural pest species and provide tools to aid in its management.

Existing taxonomic classifications of North American Conotrachelus species have been tested for the first time. Using …

From Property Abandonment To Predatory Equity: Writings On Financialization And Urban Space In New York City, Desiree Justina Fields

Dissertations, Theses, and Capstone Projects

Financial markets, actors and imperatives are increasingly central to today's global capitalism, even in areas of the economy traditionally distinct from finance, such as real estate. This financialization changes the role of mortgage capital in urban space from building place-bound wealth to facilitating the extraction of value from place. This dissertation addresses questions about how financialization operates in the rental market, specifically its relation to: earlier processes of urban disinvestment, ongoing social and political struggles around urban space, the meaning of home and social reproduction. These questions correspond to broader theoretical debates about the contingent relationship between today's urban context …
