Wetlands are the world’s largest natural source of methane, a powerful greenhouse gas. The strong sensitivity of methane emissions to environmental factors such as soil temperature and moisture has led to concerns about potential positive feedbacks to climate change. This risk is particularly relevant at high latitudes, which have experienced pronounced warming and where thawing permafrost could potentially liberate large amounts of labile carbon over the next 100 years. However, global models disagree as to the magnitude and spatial distribution of emissions, due to uncertainties in wetland area and emissions per unit area and a scarcity of in situ observations. …

Tipping Point Of A Conifer-Based Ecosystem Under Severe Drought, Kaicheng Huang, Chuixiang Yi, Donghai Wu, Tao Zhou, Xiang Zhao, William J. Blanford, Suhua Wei, Hao Wu, Du Ling, Zheng Li

Publications and Research

Drought-induced tree mortality has recently received considerable attention. Questions have arisen over the necessary intensity and duration thresholds of droughts that are sufficient to trigger rapid forest declines. The values of such tipping points leading to forest declines due to drought are presently unknown. In this study, we have evaluated the potential relationship between the level of tree growth and concurrent drought conditions with data of the tree growth-related ring width index (RWI) of the two dominant conifer species (Pinus edulis and Pinus ponderosa) in the Southwestern United States (SWUS) and the meteorological drought-related standardized precipitation evapotranspiration index …

Music: Its Language, History, And Culture, Douglas Cohen, Brooklyn College Library And Academic It

Open Educational Resources

From Cohen’s proposal:

In 2006 faculty of the Conservatory of Music wrote and published their own textbook for Core Curriculum 1.3 (CC 1.3), Music: Its Language, History, and Culture. Published by Kendall-Hunt, the reader was bundled with a subscription to the Rhapsody music streaming service. The reader and music service were to give a skeletal structure for all instructors of CC 1.3 for the development of course content focusing on the individual musical strengths and interests of each instructor. We also wanted to keep the costs to students as low as possible by not taking any royalties. The result was …

Roads To Progress: Public Perceptions Of Highway Construction In Peru, 1920–30, Mark Rice

Publications and Research

This paper, presented at the AHA/CLAH Annual Meeting in 2015 examines how Peruvians viewed the ongoing construction of roads in the early twentieth century. I argue that public support for road construction stemmed from the perception that such infrastructure would economically and culturally modernize Peru.

Exploring Social Networking Technologies As Tools For Hiv Prevention For Men Who Have Sex With Men, Jorge Ramallo, Thomas Kidder, Tashuna Albritton, Gary Blick, John Pachankis, Valen Grandeleski, Trace Kershaw

Publications and Research

Social networking technologies are influential among men who have sex with men (MSM) and may be an important strategy for HIV prevention. We conducted focus groups with HIV positive and negative participants. Almost all participants used social networking sites to meet new friends and sexual partners. The main obstacle to effective HIV prevention campaigns in social networking platforms was stigmatization based on homosexuality as well as HIV status. Persistent stigma associated with HIV status and disclosure was cited as a top reason for avoiding HIV-related conversations while meeting new partners using social technologies. Further, social networking sites have different social …

"They Shall Not Pass:" Opposition To Public Leisure And State Park Planning In Connecticut And On Long Island, Kara M. Schlichting

Publications and Research

Estate owners in Greens Farms in Westport, Connecticut, and on the North Shore of Long Island doggedly fought inclusive, state-sponsored public recreation in the 1910s and 1920s. Private land-use goals shaped localism and, in turn, exploited home rule governance to control public land use. This study of local politics in the New York metropolis contributes to the ongoing regionalization of urban history. These home rule fights against state parks reveal the extent to which elite local interests systematically exploited ineffective county government to block Progressive-era regionalism. For all the interest shared by urban historians on the topic of real estate, …

Connecting The Point(S), Hunts Point, Bronx, New York, Corey Clarke, Jocelyn Dupre, Leah Feder, Sarah Gelder, Nate Heffron, Stephanie Printz, Josh Thompson, Laxmi Ramasubramanian

Publications and Research

Hunts Point is a notoriously over-planned neighborhood. As the exploration of recent plans on page 15 illustrates, Hunts Point has been both the beneficiary and victim of planning efforts that have left many in the community feeling over-surveyed with inadequate results to show for it. Our client made it clear from the beginning that the community did not need another plan to sit on a shelf. Therefore, the team chose to focus on small-scale, actionable interventions that could be implemented without significant capital outlays. To this end, we began by conducting an analysis of existing conditions, investigating both the physical …

Specters Of Kurdish Nationalism: Governmentality And Counterinsurgent Translation In Turkey, Nicholas S. Glastonbury

Publications and Research

This essay examines translations of the Kurdish epic poem Mem û Zîn into Turkish, tracing the logics behind these state-sponsored translations and examining how acts of translation are also efforts to regulate, translate, and erase Kurdish subjectivities. I argue that the state instrumentalizes Mem û Zîn’s potent nationalist currency in order to disarm present and future claims of Kurdish national autonomy. Using translation as a counterinsurgent governmental tool, the state attempts to domesticate Kurdish nationalist discourses even as it reproduces them, thereby transforming Kurdish nationalism into a specter of itself. Attending to this specter, however, allows us to see how …

"Microfinance As A Determinant Of Domestic Violence In Bangladesh: Who Is At Risk?", Alvin Christian

Dissertations and Theses

This paper examines the impact that microfinance participation has on reported domestic violence rates among women in Bangladesh. While microfinance programs are aimed at reducing poverty, they may have unintended consequence and contribute to domestic violence or Intimate Partner Violence (IPV). Using nationally representative data from the Urban Health Survey (2006), I study the association between microfinance participation and domestic violence among currently married women. The outcome variable is domestic violence, which is coded as a dummy variable, where a women either has experienced domestic violence episodes or she hasn’t. Predictor variables include microfinance participation, community attitudes, liberal views, labor …

Do Oil Economies In Sub-Sahara Africa, Rebecca Girma

Dissertations and Theses

The African continent provides majority of the world’s raw material for technology and fine jewelry. Countries dependent on their extractive industries lag behind on developmental goals. Their GDPs are high as well as their national poverty levels. This paper explores the factors in which a nation lacks development when it is financially wealthy to do so. There are similar patterns in nations where resource curse has occurred. What is the key to sustainable development in Sub-Saharan Africa? Is solving corruption and migrating away from a market dependent on primary exports the answer? Can they transition from the ancient patrimonial state …

Empirical Investigation Of Samhsa’S (Substance Abuse And Mental Health Services Administration) Model Of Wellness, Dipanjana Das

Dissertations and Theses

The quest to operationalize the construct of wellness has been elusive. Part of the difficulty resides in the way wellness has been conceptualized in the literature, using different non-overlapping models. Another drawback is that many existing models are not based on solid empirical evidence. The current study addressed these limitations by assessing the empirical validity of SAMHSA’s (Substance Abuse and Mental Health Services Administration) model of wellness. We created an instrument to assess wellness based on a thorough review of the literature that serves as the basis of the SAMHSA model that can be used to assess wellness. Findings revealed …

Is The Trans-Pacific Partnership A ‘Natural’ Trade Bloc?, Matthew Ziegler

Dissertations and Theses

The Trans-Pacific Partnership began as a free trade agreement between Brunei Darussalam, Chile, New Zealand and Singapore which was enacted in 2004. Since that time, additional countries have entered into formal negotiations to expand the trade bloc, including the USA, Mexico, Peru, Australia, Malaysia, Canada, Vietnam and Japan. This paper seeks to determine whether these countries represent a ‘natural’ trade partnership by comparing and contrasting the trade complementarity index between each pair of countries within the partnership and those other countries counted in the APEC 21 countries plus India, which is a member of the RCEP trade bloc.

Effects Of Temperature Stress On Coral Fluorescence And Reflectance, Andrea Gomez

Dissertations and Theses

Around the world, climate change, land-based pollution and fishing impacts are recognized as principal threats to coral reef ecosystems. Sea surface temperatures, in particular, are expected to change dramatically over the next decades and result in high coral mortality in some regions. Through controlled experiments, I examined changes in coral fluorescence and reflectance in response to water temperature alterations to assess the potential of employing these signatures as a diagnostic tool to measure coral health. At the NOAA Coral Culture and Collaborative Research Facility, I conducted controlled laboratory-based heat stress experiments on three Caribbean species of coral: Acropora cervicornis, Orbicella …

"Model Complexity And Variable Selection In Maxent Niche Models: Analyses For Rodents In Madagascar", Peter Galante

Dissertations and Theses

Ecological niche models (ENMs) characterize the relationship between localities where a species is known to occur and the abiotic characteristics of these regions. While widely used, ENMs remain subject to several outstanding issues, including those related to model complexity and violation of modeling assumptions (e.g., representative sampling). Critical in resolving these issues is a better understanding of the effectiveness of model selection techniques. Here, I compare two strategies for optimizing ENMs: an information-criterion approach (AICc) and a sequential approach that assesses model performance on withheld data. I do so for a single species using two datasets, one with all available …

Food Imports As A Hindrance To Food Security And Sustainable Development: The Cases Of Nigeria And Senegal, Dioume Astou

Dissertations and Theses

Despite the growing global acceptance of an individual’s right to adequate food and nutrition, and the state’s obligation to ensure that all its citizens are free from hunger, 805 million or one in nine people around the world today are still chronically malnourished; the majority live in developing countries. African states have had a particular problem with food insecurity. Food security on the continent has worsened since the 1970s and by the end of the century, the population in Africa is

expected to be three times its current level. Hence, food insecurity in Africa will be much more severe than …

Degradation Of Carbon Tetrachloride Using Hydrophobic Green Rust, Sheena Bowman

Dissertations and Theses

Hydrophobic green rusts (GR) were produced using aerial oxidation of solutions containing bis (2-ethylhexyl) sulfosuccinate (BIS) and sodium N-lauroylsarcosinate (SNLS), iron (II) sulfate and sodium hydroxide. The synthesis was conduced at constant pH 8.0±0.1 for the duration of 1-3 hrs. Partition tests showed GRBIS and GRSNLS suspended in the organic phase (tetrachloroethylene). Through X-ray diffraction analysis both GRs exhibit similar patterns to Green Rust II, an inorganic form of GR. The kinetics of GR reductive dechlorination of carbon tetrachloride (CT) was investigated. CT at high concentrations was degraded at high percentages for GRBIS-3, 88.5% and GRSNLS-5, 97.6%. Their reactions were …

World Bank, Agriculture And Policy: A Case Study In Ghana And Ethiopia, Steven Margel

Dissertations and Theses

This thesis tests the effectiveness of the World Bank’s agricultural-aid policy by examining case studies in Ghana and Ethiopia in the period of 2000-2010. Each study examines the policy context, project/program success, overall human development results, and threats to sustainability, of agricultural aid. The primary hypothesis of the paper is that participatory processes and inclusive institutions will prove to be decisive factors. Each case is tested against this political view of aid in addition to three additional images (Destructive, Ineffective, Effective Technical), in order to ensure a comprehensive review.

The Ghana case showed a lack of participation in forming the …

Intra- And Inter-Seasonal Variability Of Supra-Glacial 1 Streams And Lakes Over The West Greenland Ice Sheet 2 From High-Resolution Satellite Optical Data, Michael Gregory Brown

Dissertations and Theses

The Greenland ice sheet (GrIS) is one of the largest glacial ice masses on Earth, second only to the Antarctic ice sheet. The surface hydrology of the GrIS plays a crucial role on the surface energy and mass balance budgets of the ice sheet as a whole. Surface water, known as supra-glacial water, is seasonally found in the ablation zone and feeds the en-glacial and sub-glacial hydrological environments of the ice sheet. The spatial distribution of surface streams is poorly understood and their temporal variability is (to our knowledge) unknown. One of the reasons for the lack of knowledge on …

Factors Affecting Developing Planning In Africa: The Need For Local Input, Ismael Sow

Dissertations and Theses

Africa has become synonymous with poverty, diseases, and despair. The continent is home to the highest number of extremely poor people in the world. Throughout the world, especially in the last few decades, many countries in the so-called South have succeeded in lifting their people out of poverty. The continent, with the exception of a few African countries, has failed to design and implement sound economic plans to bring prosperity to a billion Africans. This thesis proposes that for African countries to develop, ways should be found to include indigenous input into development planning. This assumption is based on both …

Towards A Theory Of Gis Program Management, Jochen Albrecht

Publications and Research

After a brief flurry of monographs on business and organizational aspects of GIS in the 1990s, little attention has been paid to a systematic approach in support of GIS Program management. Most existing efforts in both public and private enterprises are based on anecdotal evidence. This chapter outlines a range of research questions and the beginning efforts to study modern GIS management practices and help develop a body of knowledge that can be used for the accreditation of GIS Programs and the certification of GIS Program managers.

The Odds And The Ends: What To Do With Some Letters Of Catharine Macaulay, Olivera Jokic

Publications and Research

Biographers of Catharine Macaulay (1731–91), much like her contemporaries, often agreed that the woman’s reputation was shaped by the peculiar company she kept: prominent, intellectual, political, radical, revolutionary, and occasion- ally “foolish.”3 This essay examines why it matters what company a writer keeps, especially when that writer is a woman and her reputation is tied to the status of her letters and her correspondents.

The Effects Of Merging Proactive Cctv Monitoring With Directed Police Patrol: A Randomized Controlled Trial., Eric L. Piza, Joel M. Caplan, Leslie W. Kennedy, Andrew M. Gilchrist

Publications and Research

Objectives: This study was designed to test the effect of increased certainty of punishment on reported crime levels in CCTV target areas of Newark, NJ. The experimental strategy was designed for the purpose of overcoming specific surveillance barriers that minimize the effectiveness of CCTV, namely high camera-to-operator ratios and the differential response policy of police dispatch. An additional camera operator was deployed to monitor specific CCTV cameras, with two patrol cars dedicated to exclusively responding to incidents of concern detected on the experimental cameras.

Methods: A randomized controlled trial was implemented in the analysis. A randomized block design was used …
