High Carbon And Biodiversity Costs From Converting Africa's Wet Savannahs To Cropland, Timothy D. Searchinger, Lyndon Estes, Philip K. Thornton, Tim Beringer, An Notenbaert, Daniel Rubenstein, Ralph Heimlich, Rachel Licker, Mario Herrero

Geography

Do the wet savannahs and shrublands of Africa provide a large reserve of potential croplands to produce food staples or bioenergy with low carbon and biodiversity costs? We find that only small percentages of these lands have meaningful potential to be low-carbon sources of maize (1/42%) or soybeans (9.5-11.5%), meaning that their conversion would release at least one-third less carbon per ton of crop than released on average for the production of those crops on existing croplands. Factoring in land-use change, less than 1% is likely to produce cellulosic ethanol that would meet European standards for greenhouse gas reductions. Biodiversity …

Detergent Less Ultrasound-Assisted Extraction Of Trace Elements From Edible Oils Using Lipase As An Extractant, Derya Kara, Andrew Fisher, Steve Hill

School of Geography, Earth and Environmental Sciences

A new method for the extraction and preconcentration of trace elements (Al, Ba, Cd, Cu, Fe, Mn, Mo, Ni, Ti, V and Zn) from edible oils by producing detergentless micro-emulsions via an ultrasound-assisted extraction using a water phase containing Lipase at pH 3 as an extractant was developed. The trace elements in the water phase post-extraction were determined against matrix matched standards using ICP-MS. In the first step of the work, the parameters that affect extraction, such as pH, the volume of 1% lipase in the water phase and the ultrasonic and centrifugation times were optimized. Under the optimal conditions, …

The Human Ecology Dialectic: Culture As A Behavioral Adaptation, Marcia S. Taylor

The Hilltop Review

Contrary to popular thought, which implicated the disengagement of Marx from anthropological theory, his dialectical concept will be applied to explain human ecology in a Boasian historical particularism milieu. Environmental conditions will be the common denominator for the Darwinian biogeography theory, intertwined with the cultural adaptation theory of Boas within the Human Ecology Dialectic (Taylor, 2014). Anthropologically, in a biological context the theories will explain the behavioral adaptation process demonstrated culturally by the prehistoric ancestors of the Inuit of the Canadian Central Arctic in their development and essential engagement in the creation of art; a pursuit that became a cultural …

Report On The Sacred Heart University Participation In The Ace Internationalization Laboratory By The American Council On Education Peer Review Visit Team February 25-27, 2015, American Council On Education Peer Review Visit Team

Emerging Roles Of Health Care Providers To Mitigate Climate Change Impacts: A Perspective From East Harlem, New York, Perry E. Sheffield, Kathleen T. Durante, Elena Rahona, Christina Zarcadoolas

Publications and Research

Professional associations of health care workers are issuing policy statements on climate change and health with greater frequency, calling on their members to act in their duty to protect and fulfill the right to health. These health care providers’ perceptions of their roles in the intersection of climate and health, however, have not been well-studied. This article presents results from a qualitative study using focus groups conducted with health care providers serving the low-income, ethnic minority population in East Harlem, New York. The focus groups sought to identify and explore providers’ perceived health threats of climate change, as well as …

Language And Thought In Egypt's Schools Today: What Does Arabic Mean To Arabic Native Speakers? A Literature Review, Diego Dalle Carbonare

Capstone and Graduation Projects

Sociocultural education initiated by Leo Vygotsky strongly believes that language of instruction affects thinking. With regards to the present situation in Egypt, the present research explores the current literature on the value that Arabic has in the Arabic speaking world. Over against a wide-spread opinion that English should be used as the only medium of instruction in early years of literacy, literature shows that some forms of immersion have negative impact on the mastery of mother tongue, and on the very development of cognitive skills. The linguistic and educational scenario is further complicated by the fact that Arabic is a …

Transferring Hypothetical Deductive Reasoning, Jordan Hatch, Jamie L. Jensen

Journal of Undergraduate Research

The purpose of our project was to understand if hypothetical deductive (HD) reasoning skills exist in each discipline and if so, whether they are transferable between disciplines. HD reasoning is the method of scientific investigation used most commonly by scientists. It includes formulating hypotheses, devising experiments, making predictions, and analyzing results (iSTAR 2013). Many science classes boast scientific reasoning as a main learning outcome, but does reasoning transfer between disciplines and thus benefit the person as a whole? We hypothesized that most, if not all, disciplines use HD reasoning. In addition, we hypothesized that because this skill is context independent …

Using Spatiotemporal Methods To Fill Gaps In Energy Usage Interval Data, Kristin K. Graves

Theses and Dissertations

Researchers analyzing spatiotemporal or panel data, which varies both in location and over time, often find that their data has holes or gaps. This thesis explores alternative methods for filling those gaps and also suggests a set of techniques for evaluating those gap-filling methods to determine which works best.

Health Exposure, Socio-Economic Vulnerability, And Infrastructure At Risk To Current And Projected Coastal Flooding In New York City, Lesley Patrick

Dissertations, Theses, and Capstone Projects

This work uses a GIS-based methodology to develop and map a composite physical exposure, social vulnerability, and critical facilities index for New York City populations exposed to the current and predicted 100- and 500- year coastal floods. The objective is to illustrate how sea-level rise may affect future 100- and 500-year coastal floods in New York City, how these changes in future flood scenarios will affect the number and distribution of people at risk and their associated physical and socioeconomic impacts, and how these impacts will vary among neighborhoods.

Sea-level rise throughout the 21st century will result in increased flood …

Ecomusicology: Back To The Roots Of Sound/Music And Environmental Sustainability, Tiffany Challe

Dissertations, Theses, and Capstone Projects

We are currently living in the midst of a global warming crisis, and running against the clock to counter the rapid depletion of natural resources in an increasingly technology-run world. The first step toward sustainability is to care for our world that is full of vibrant ecosystems and that we must work together to preserve. While the visual arts have served as a cogent platform for the environmental movement, this paper will argue that sound and music have been vastly overlooked in sustainability topics. Place-making music can capture a place's unique spirit and connect listeners with their local ecologies. Therein …

Civil War Incentives, Identities, And Group Allegiances In Syria's Contested Provinces: A Case Study On Civil War, Hilary Weitze

Dissertations, Theses, and Capstone Projects

This project seeks to answer the following questions: Why did the 2011 Syrian Revolution transition into a civil war? What contributed to the popularity of rebel efforts in the countryside? This case study on the Syrian Civil War begins by characterizing key events in the current civil war setting in order to characterize the nature of participation on the insurgent side of the conflict. Further, this project sets out to identify key events and actors in their respective geographic and demographic frameworks in order to identify the nature of participants and their respective characteristics. I will ultimately draw a connecting …

Psychosocial Sequelae Of Homicide Among Murder Victims' Family Members: An Appraisal Of Depression, Grief, And Posttraumatic Stress, Sarah Kopelovich

Dissertations, Theses, and Capstone Projects

The current investigation explored what is known regarding the psychological sequelae of the post-homicide experience for murder victims' family members and friends (MVFM). Participants were also asked about whether they felt they had attained closure, a term which populates anecdotal and theoretical accounts of MVFM's experience. Previous literature guided a theoretical definition of closure as a dimensional construct that represents adaptive functioning following a murder, and includes (1) absence of disabling symptomatology, (2) absence of ruminations about the event or murder victim, and (3) subjective return to baseline functioning. This quasi-experiment consisted of a between-subjects cross-sectional design. The dependent variable …

Rebellion Under The Palm Trees: Memory, Agrarian Reform And Labor In The Aguán, Honduras, Andres Leon

Dissertations, Theses, and Capstone Projects

On December 9, 2009, the Unified Peasant Movement of the Aguán (Movimiento Unificado Campesino del Aguán; MUCA) occupied over 20,000 hectares of oil palm covered lands in the Aguán region in the Honduran northern coast. This was the latest, and probably most dramatic, chapter in the region's tumultuous recent history. This dissertation explores this history and the process of creation of the Aguán region from the perspective of a set of impoverished peasant families that migrated from different parts of Honduras towards the Aguán from the 1970s onwards, in search of a better present and future.

It asks about the …

Income Inequality And Vulnerabiility To Flood Hazard In Brazil, Rebecca Rasch

Dissertations, Theses, and Capstone Projects

Social theorists suggest that income inequality within a society leads to a breakdown of social cohesion, spatial segregation, and as a result, uneven public resource access. I will assess whether this social phenomenon is important to consider when measuring vulnerability to climate change in urban, middle-income countries. To test this relationship, I create a flood hazard vulnerability index at the municipality level and determine whether income inequality, measured at the municipality level, is a predictor of municipality vulnerability to flood hazard. The flood hazard vulnerability index incorporates socioeconomic, built environment and natural environment data, providing a more holistic approach to …

The Ones Left Behind: Making The Connection Between Poverty And The Achievement Gap, Audrey Davis

Dissertations, Theses, and Capstone Projects

The achievement gap has been a major issue plaguing the education system in the United States for decades. There has been much research conducted with the goal of identifying the reasons for the achievement gap. One of the main reasons for the achievement gap is poverty. In fact, I argue that there is a direct correlation between academic achievement and poverty, in other words school and society are inextricably connected. The focus of this paper will be the elementary school level as there is an abundance of information on elementary schools in New York City. To further demonstrate the fact …

Narratives Of Interiority: Black Lives In The U.S. Capital, 1919 - 1942, Paula C. Austin

Dissertations, Theses, and Capstone Projects

This dissertation constructs an urban, social and intellectual history of poor and working class African Americans in the interwar period in Washington, D.C. Although the advent of social history shifted scholarly emphasis onto the "ninety-nine percent," many scholars have framed black history as the story of either the educated, uplifted and accomplished elite, or of a culturally depressed monolithic urban mass in need of the alleviation of structural obstacles to advancement. A history of the poor and working class as individuals with both ideas and subjectivity has often been difficult simply because there are limited archival sources.

"Narratives of Interiority" …

Luti Masculinity In Iranian Modernity, 1785-1941: Marginalization And The Anxieties Of Proper Masculine Comportment, Robert Joseph Bell

Dissertations, Theses, and Capstone Projects

This paper offers a genealogy of changing conceptualizations and performances of masculinity in 19^th and early to mid-20^th century Iran, and examines in particular a unique group of masculine subjects known as the lutis. The first component of the analysis traces the historical lineage of these lutis, situating their emergence out of Persian Sufi brotherhoods, bandit clans ('ayyar), and guild-like organizations (futuwwa) from the period of the 15th to the 19th century CE. This section provides an account of the most pertinent and distinguishing rites, attitudes, and practices of the …

Blessed Disruption: Culture And Urban Space In A European Church Planting Network, John D. Boy

Dissertations, Theses, and Capstone Projects

New Protestant churches are being founded in cities around the world. They are the product of a conscious effort on the part of evangelicals to found, or ``plant,'' new churches in urban areas. Behind this effort are a whole host of actors, including denominations, churches, seminaries, and parachurch organizations, who come together in church planting networks to establish theologically conservative churches that will speak to young urban professional audiences. The hope is that these efforts will scale up and turn into a movement bringing about religious revival among culturally influential groups. Among the focal areas for these efforts are European …

Archiving The City: A Guide To The Art Of Urban Interventions, Olatokunbo Adeola Enigbokan

Dissertations, Theses, and Capstone Projects

The topic of this dissertation is the development and exploration of alternative methodologies for understanding and relating to everyday urban experience. The project is a psychogeographical exploration of methodologies used in contemporary art and architectural practice to create street-level "urban interventions." For the purposes of this study, urban interventions are defined as actions, performances, installations and objects created by artists, and or activists and sometimes architects, and inserted into, or responsive to, everyday urban environments, usually taking place outside of official art spaces, such as museums and galleries. In most cases these interventions are unexpected, express a "do-it-yourself" aesthetic and …

Growing Up Online: Identity, Development And Agency In Networked Girlhoods, Claire M. Fontaine

Dissertations, Theses, and Capstone Projects

Young women's digital media practices unfold within a postfeminist media landscape dominated by rapidly circulating visual representations that often promote superficial readings of human value. Meanwhile the dominant framing within educational policy and practice of digital media literacy insufficiently captures young people's motivations for engaging in multimedia production, online gaming and blogging. In addition to using digital media for social purposes, and to navigate dimensions of social difference like race, class and gender, working class young women of color also use digital media to develop internal awareness of their selves. The processes of documenting the self, reflecting on the documented …

Black Migrant Literature, New African Diasporas, And The Phenomenology Of Movement, Christopher Ian Foster

Dissertations, Theses, and Capstone Projects

Black Migrant Literature, New African Diasporas, and the Phenomenology of Movement examines immigration, diaspora, and movement in late twentieth and twenty-first century African literature. "Migritude" describes the work of a disparate yet distinct group of contemporary African authors who critically focus on migration within the context of globalization, emphasizing that the "past" of immigration is irreducibly entangled with colonial processes. These writers often refashion the politics or discourses of earlier movements within the black radical tradition, such as Négritude or pan-Africanism, as a way to engage immigration in the present. I argue that although immigration as a system developed as …

Carbon Emission Policy In The United States: State Patchwork Vs. National Policy, Samuel T. Frank

Dissertations, Theses, and Capstone Projects

The lack of a national law in the United States to mitigate climate change has prompted many states and cities to take the lead in implementing policies to reduce their carbon emissions and adapt to the threats posed by a warming planet. This project adopts two established systems that classify states by their relative involvement in climate policy (Wheeler 2010; Lutsey et al. 2008) and combines them into a single, six-point ranking scale. States are then cross-tabulated against EPA data showing the amount and trajectory of each state's carbon emissions from the electrical power sector over the period 2005-2010. States …

The State Of The Oligocene Icehouse World: Sedimentology, Provenance, And Stable Isotopes Of Marine Sediments From The Antarctic Continental Margin, Daniel William Hauptvogel

Dissertations, Theses, and Capstone Projects

The Oligocene Epoch (34-23 Ma) was a dynamic time in Antarctica, with previous ice volume estimates suggesting fluctuations from below 50 % up to 140 % of modern all while atmospheric CO₂ decreased from above 1,000 ppm in the Early Oligocene to near modern levels by the Late Oligocene. Most of what is known about the Oligocene Antarctic cryosphere however, is derived from distal sedimentary records that can only provide a generalized view of the cryospheric dynamics in Antarctica. To better understand regional differences in Antarctic glacial dynamics, proximal records are needed. This dissertation advances our understanding of these …

Do Cultural And Perceptual Factor Matter?: An Investigation Of Factors Impacting Intelligence Test Scores Of Latinos/Hispanics In The United States, Mary E. Ignagni

Dissertations, Theses, and Capstone Projects

This paper examined societal and cultural explanations regarding the score differences seen between Latinos/Hispanics and Whites on intelligence tests through focusing specifically on possible explanations for the scores obtained by Latino/Hispanic test-takers. In this paper, it was argued that additional unique factors may impact the test scores of Latino/Hispanic test-takers. Specifically, racial and ethnic self-identification, ethnic centrality, acculturation, cultural distance, test perceptions, and ethnicity were explored as possible unique factors. In addition, an attempt was made to explain within group differences. A non-experimental study was utilized in which a final sample of 194 participants completed an intelligence test and measures …

Bad Apple: Complexities Of New York City Food Aid Programs, Rose Meagan Jimenez

Dissertations, Theses, and Capstone Projects

The only universal thing about food is that everyone needs to eat. In the United States, there are more instances of food insecurity than impoverishment. Governmental and local food aid programs are complex but are essentially motivated by socioeconomic issues. Food aid programs, from community gardening to Food Stamps, initially stem from a depression-era need to stimulate the economy. However, as socioeconomic issues change, food aid programs also evolve to meet those needs. By excavating different pieces of literature that discuss issues in food aid, the forms of structural violence that cause hunger come to life. This piece discusses community …

Obstruent Voicing And Tone In Siklis Gurung, Danielle Ronkos

Dissertations, Theses, and Capstone Projects

This thesis examines proposals for the tone system of Gurung, a Sino-Tibetan language spoken in Nepal, in light of data collected from a speaker of Siklis Gurung. Although Gurung is widely acknowledged to be a tonal language, existing descriptions of Gurung disagree as to how these tone categories should be defined and whether word-initial obstruent voicing is phonemic or allophonic. The data presented in this paper suggests that, despite claims otherwise, voicing is phonemic in some dialects of Gurung. It also suggests that Siklis Gurung is best analyzed as having three tone categories: a low tone that occurs with breathy …

Foreign Direct Investment And The Chinese Economy: Theory And Impact, Gerasimos Seriatos

Dissertations, Theses, and Capstone Projects

The Chinese economy has sustained a high rate of growth during the last three decades. This economic growth has been the outcome of an innovative strategy, which the Chinese leadership has been implementing within the model of the state directed economy. This strategy has been manifested in a variety of tactical moves one of which is the utilization of Foreign Direct Investment as a source of finance and industrial know-how. The argument in this study is that Foreign Direct Investment has positively contributed to the phenomenal growth of the Chinese economy. Moreover, the performance of Foreign Direct Investment in China …

Phylogeography Of Southeast Asian Flying Foxes (Chiroptera: Pteropodidae: Pteropus), Susan Man Shu Tsang

Dissertations, Theses, and Capstone Projects

Flying foxes (Pteropus) are a genus of Old World fruit bats that are important seed dispersers and pollinators for plants native to the 200,000+ islands in Southeast Asia, yet they are some of the most poorly known bats in the world. They comprise some of the largest known bat species, and are morphologically relatively conserved on the genus level. Pteropus is the most species-rich genus within Pteropodidae, though the origin for this diversity remains incompletely understood. In Chapter 1, I discuss the importance of Pteropus to the ecosystem and as reservoir hosts. In Chapter 2, a molecular phylogeny is presented …

Technology And The Glass Imagination: Isolation And Closeness From The Window To The Screen, Sarah Elizabeth Welsh

Dissertations, Theses, and Capstone Projects

In computer and cell phone screens, as in 19th-century architecture, glass employs a frame to show a specific picture, and keeps us at a distance from what lies behind it. Glass' dichotomies in technology (transparency and reflection, isolation and closeness) have become stronger metaphors for our experience with technology. This paper will look at the similarities between the language and metaphors created by glass in 19th-century architecture and 21st century technology, and glass' role in connecting us to and alienating us from the world 'outside.' In so doing, the role of glass in the imagination and its impact on modernity …

Essays On The Economics And Methodology Of Social Mobility, Benjamin Zweig

Dissertations, Theses, and Capstone Projects

This dissertation consists of three essays which aim to extend the methodology and analysis of the study of social mobility. In the first essay, differences in intergenerational mobility across race and across the parent's earnings distribution are explored through a nonparametric framework. Components of mobility are differentiated and analyzed separately in order to get a comprehensive account of heterogeneities in mobility. Several important differences are found including higher expected mobility for white households, higher idiosyncratic mobility for black households, larger disparities in expected mobility at the high end of the earnings distribution, and much higher rates of overall intergenerational persistence …
