Essays On International Trade And Economic Growth, Mateo Hoyos

Doctoral Dissertations

In this dissertation I study the relationship between trade and economic growth, with a focus on developing economies. I specifically provide a critical review of the consensus view in trade and growth, according to which a liberal trade regime is generally the best policy stance to promote growth. In the first essay of this dissertation, I provide evidence that the relationship between trade policy and growth may depend on economic structure: tariff reductions are followed by higher levels of GDP per capita for manufacturer countries, but lower levels for nonmanufacturers. Testing for mechanisms, I find the heterogeneity seems to be …

Three Essays On Macroeconomics And Development, Guilherme Klein Martins

Doctoral Dissertations

This dissertation is a collection of essays that relate, in different forms, macroeconomic policies to economic development. Essay 1 provides evidence that austerity shocks have longrun negative effects on GDP. Besides addressing the important gap in the growing fiscal research regarding the short time horizon of the estimations, the paper analyzes two other important assumptions made in the literature regarding the (i) symmetry of episodes of fiscal expansion and contraction and (ii) uniformity of fiscal multipliers for different sizes of shocks. We use narrative fiscal shocks and propensity score reweighting in a local projections setup to account for the potential …

Activation Of Nrf2 At Critical Windows Of Development Alters Protein S-Glutathionylation In The Zebrafish Embryo (Danio Rerio), Emily G. Severance

Masters Theses

Perturbation of cellular redox homeostasis to a more oxidized state has been linked to adverse human health effects such as diabetes and cancer. However, the impact of altering the regulation of redox homeostasis during development is not fully understood. Specifically, this project investigates the role of the Nrf2 antioxidant response pathway and its effect on glutathione (GSH; cellular redox buffer) at critical windows of development. To explore this, we used zebrafish embryos (Danio rerio) as a model due to the function of GSH and the Nrf2 being conserved among vertebrates. We exposed zebrafish embryos to three Nrf2 activators: two antioxidant …

Platforms And Power: Transnational Guatemala, Eric Sippert

Doctoral Dissertations

Moving beyond studies of social movements and NGOs, this dissertation examines how grassroots groups in Guatemala use transnational flows of goods, ideas, and people to create new organizational forms and types of political action. This case study of an organization of returned migrants, former combatants, and indigenous youth demonstrates how marginalized groups create platforms that facilitate connections between disparate actors across nation-state and identity borders. Drawing on field research in Guatemala’s Western Highlands, I explore how these platforms emerged, threats to them, their effects, and what they can teach us about political organizing in crisis. I begin by tracing the …

Effects Of Berberine On Development In Caenorhabditis Elegans, Zhuojia Qian

Masters Theses

Berberine is an isoquinoline alkaloid found in some plants and has many bioactivities including anti-microbial, lipid- and glucose-lowering, anti-cancer, anti-inflammatory, etc. However, there is limited knowledge about berberine’s effects on development and locomotive activity. Herein, in vivo studies were conducted to determine these effects of berberine using Caenorhabditis elegans as an in vivo model. Treatment of berberine at 50 μM starting at L1 stage significantly retarded the growth rate of nematodes, and reduced the length, width and moving speed of worms by 19%, 12% and 29%, respectively, compared to the control. In addition, triglycerides (TG) and protein content in worms …

Patterns Of Morphological Plasticity In Metriaclima Zebra And Danio Rerio Suggest Differently Canalized Phenotypes Due To Form-Function Relationships, Dylan Jockel

Masters Theses

In order to ascertain the degree of compatibility in developmental restructuring and behavioral plasticity between two fish species frequently made subject of laboratory research (Metriaclima zebra & Danio rerio), alternative trophic niche exposure experiments utilizing novel three-prong feeding treatments were conducted to obtain morphometric data, which demonstrated both species do bear some degree of plasticity. The results are somewhat complicated by differences in locality of detectable restructuring, which may be due to disparity in the form-function relationship for each species’ lineage. Each is notable in the manner of respective species’ jaw protrusion, as it is driven by anterior …

Determining Kinetic Parameters Of Thiamine Degradation In Three Nasa Spaceflight Foods In Thermal Processing And Long-Term Storage And Methods For Analyzing Microstructure And Precipitant Development In Real And Model Wines, Timothy R. Goulette

Doctoral Dissertations

The current NASA spaceflight food program encompasses a wide variety of commercial and custom-made edible products. These foods are designed to ensure each crewmember receives the Recommended Dietary Allowance (RDA) of vitamins and minerals to maintain adequate health during the entire spaceflight mission. With the desire for long-duration and exploration-class missions, such as the impending mission to Mars, the retention of important nutrients such as labile vitamins in spaceflight foods is critically important. For this reason, multiple studies were conducted to determine the vitamin degradation behavior of thiamine (vitamin B₁) within three spaceflight foods which demonstrated both significant …

Epigenetic Regulation Of Genomic Imprinting During Early Mammalian Embryonic Development, Chelsea Marcho

Doctoral Dissertations

Mammalian development involves remarkable changes, starting from a single-cell, totipotent zygote and ending with a developed organism comprised of diverse cells types with distinct morphologies, structures, and functions. Within three days of murine development, the two parental genomes merge into a single nucleus, begin zygotic gene expression, undergo epigenetic remodeling, and make the first lineage decisions. Diversity in cell-types is possible even though cells share the same genome. This diversity is achieved by the tight regulation of differential transcriptional programs. There are many ways these transcriptional programs can be initiated. Epigenetic alterations to the genome can drive transcriptional changes. Epigenetic …

Influence Of Household Chaos On Associations Between Physiology And Behavior, Sarah Mccormick

Masters Theses

Internalizing behaviors, or behaviors related to behavioral inhibition and the tendency to withdraw from novelty or uncertainty, are stable over time. There is substantial evidence indicating the association between greater resting right lateralized frontal EEG alpha asymmetry and negative affect as well as internalizing behaviors (Coan & Allen, 2003; Henderson, Fox, & Rubin, 2001; Fox, 1991). Further, right frontal asymmetry has been shown to be a stable marker of the presence of psychosocial risk (e.g. child maltreatment; see Peltola, Bakermans-Kranenburg, Alink, Huffmeijer, Biro, & van IJzendoorn, 2014 for meta-analyses). However, little is known about the influences of the home and …

Methylglyoxal Influences Development Of Caenorhabditis Elegans Via Heterochronic Pathway, Jiaying Wang

Masters Theses

Methylglyoxal is a highly reactive dicarbonyl compound, which is widely distributed in food products and beverages, and is particularly high in Manuka honey. In addition to its antibacterial effects, methylglyoxal is also known as a major precursor of advanced glycation end products (AGEs), that produces altered macromolecules (such as proteins and DNA), leading to abnormal physiological changes. However, the effects of methylglyoxal on development is unclear. Thus, this study aimed to determine the role of methylglyoxal in this aspect using Caenorhabditis elegans (C. elegans). Treatment of methylglyoxal at 0.1 mM and 1 mM for 48 h significantly inhibited …

Distribution And Population Dynamics Of Ungulates In The Mongolian Gobi, Buuveibaatar Bayarbaatar

Doctoral Dissertations

The Mongolian Gobi is one of the most spectacular and important regions in Central Asia, comprising the largest area of intact grassland in the world. In recent years, a growing human population, expanding exploitation of natural resources, and the development of infrastructure in the region place increasing pressure on these species and their habitats. This dissertation has focused on three species of ungulates such as Mongolian saiga (Saiga tatarica mongolica) in western Mongolia, and Asiatic wild ass (Equus hemionus), and goitered gazelle (Gazella subgutturosa) in Southern Gobi. The study on endangered saiga antelope in …

Infants' Reasoning About Agents' Identity: The Case Of Sociomoral Kinds, Hernando Taborda

Doctoral Dissertations

Recent studies in development psychology suggest that early on infants are able to distinguish characters who display a cooperative behavior from characters who display an antisocial behavior. The current research builds on these findings and aims at determining the extent to which infants possess the sociomoral distinction of “good” and “mean” agents. In particular, we propose that infants represent sociomoral behaviors through kind-based categories. This hypothesis was tested in the current research across 5 different experiments by investigating how infants represent the identity of agents in sociomoral situations. Experiment 1 used a looking-time paradigm to demonstrate 11-month-old infants’ bias to …

The Political Economy Of Smallholder Incorporation And Land Acquisition, Alfredo R. Rosete

Doctoral Dissertations

Of late, development institutions and economists have argued that one way to accomplish the modernization, and thus, poverty alleviation in the rural sector is through smallholder incorporation- partnerships between agribusiness firms and smallholders in order to cultivate high valued export crops. Smallholders in developing countries often face numerous challenges that result in low incomes, and limited opportunities. As a result of these challenges, smallholders in developing countries continue to cultivate subsistence crops, or, use less technologically intensive techniques. Thus, many are unable to maximize the use of their holdings. Agribusiness firms may provide the material inputs, infrastructure, and transport needed …

Effects Of Adolescent Alcohol Binge Drinking On Prefrontal Myelin, Wanette M. Vargas-Rodriguez

Doctoral Dissertations

Alcohol binge drinking is highly prevalent in teenagers and is associated with various harmful health effects and social problems. During adolescence, brain regions such as the prefrontal cortex (PFC) are still undergoing active development, characterized by increases in white matter volume. While the morphological details and the cellular and molecular sequences governing adolescent white matter development are not fully known, it is known that this development process is sensitive and can be disrupted. Although consumption of alcohol in a binge drinking pattern has been linked to lower white matter integrity in humans, it is important to determine if alcohol is …

Colonial And Post-Colonial Origins Of Agrarian Development: The Case Of Two Punjabs, Shahram Azhar

Doctoral Dissertations

This study explores the colonial and post-colonial origins of agrarian development by looking at the role of historical institutions, class formations and the state (ICS) in shaping the process. It contributes to the “divergence debates” in economics, which make an attempt to explain the ‘fundamental causes’ of divergence between countries. While one strand of the divergence literature presents the process as being functional to ‘geography’, a second strand focuses on the institutional legacies of colonialism; what is common to both sets of explanations, however, is the view that future outcomes are completely pre-determined by one or another time-invariant factor, leading …

Managing The Agricultural Biotechnology Revolution: Responses To Transgenic Seeds In Developing Countries, Alper Yagci

Doctoral Dissertations

There has been heated debate over transgenic or genetically modified (GM) crops in agriculture. Advocates and critics argue over possible economic, environmental, public health implications of this technology. This study examines varying policy approaches to regulating GM crop cultivation in four developing countries where the technology has large potential application. Why have some countries banned GM crop cultivation in their territory while others encouraged it? In countries where GM crops were allowed, why have varying systems of intellectual property rights (IPR) protection been constructed? To investigate these questions I comparatively examine the policy experience (1995-2015) of Argentina, Brazil, Turkey relying …

Evolvability Of The Skull: A Study Of Genetic Basis And Integration In The Teleost Craniofacial Skeleton, Yinan Hu

Doctoral Dissertations

As the field of evolutionary biology pivots away from a gene-centric view of how adaptive evolution proceeds, renewed emphasis is placed on the origin of phenotypic variation. Understanding the developmental processes that underlie the production of novel traits, and how they might influence evolvability, is considered a primary goal in the on-going “extended evolutionary synthesis”. The following dissertation explores these questions in the context of adaptive radiations in fish, with a focus on morphological variation in the craniofacial skeleton. Specifically, the first chapter investigates the genetic and developmental basis of shape (co-)variation in the feeding apparatus of African cichlid fishes, …

Structural Transformation, Culture, And Women’S Labor Force Participation In Turkey, Yasemin Dildar

Doctoral Dissertations

Turkey has experienced important structural and social changes that would be expected to facilitate women’s participation in market work. Social attitudes toward working women have changed in recent years; women are becoming more educated; they are getting married at a later age; and fertility rates are declining. Despite these factors, women’s labor force participation rates are very low in comparison to the countries at a similar development stage. This dissertation analyzes the underlying causes of low female labor force participation in Turkey. In addition to a background chapter (Chapter 2) analyzing structural transformation and employment generation patterns, the dissertation has …

Human Capital, Employment And Subjective-Objective Poverty: A Micro Case Study Of Nepal, Tejesh Pradhan

Masters Theses

This thesis derives an alternative subjective-objective poverty line (SPL) using self-reported qualitative assessments of perceived adequacy for different categories of consumption namely, food, housing and clothing. Modeling the probability of reporting that actual consumption in each category is adequate, I find that actual measures of consumption are highly significant predictors of perceived consumption adequacy. The perceived adequacy for different consumption components respond more elastically to spending on the corresponding category of goods than to that on other types. The results suggest that the implied subjective poverty lines and regional profiles are different from those predicted by popular objective methods.

The Pervasiveness Of Technocracy In Sanitation Development And Its Impact On Project Sustainability: A Case Study Of The Microbial Fuel Cell Latrine Pilot Project In Nyakrom, Ghana, Kathryn E. Fox

Masters Theses

Approximately 2.5 billion people in the world currently lack access to adequate sanitation facilities. Improving sanitation access in the developing world is vitally important to public health, economies, and the environment. Non-governmental organizations and the private sector have played a significant role in increasing sanitation access through the construction of sanitation and hygiene systems. However, these projects have been plagued with sustainability problems with the rate of non-functional systems remaining consistently at 30 to 40 percent since the 1980s. Studies have found that meaningful community engagement and the consideration of community capacity during project development are vitally important to long-term …

Essays On The Evolution Of Inequality, Cem Oyvat

Doctoral Dissertations

This dissertation examines the evolution of inequality during the development process. Specifically, the study will focus on two factors that crucially in influence the evolution of distribution: 1) industrialization and urbanization, and 2) agrarian structures and land inequality. The dissertation consists of three essays: The first essay examines the impact of the initial conditions of agrarian structures on income inequality over the long run. It develops a model showing that at the same level of national income, countries with more unequal land distribution can be expected to experience greater agglomeration in the urban sector. The excess labor in the urban …

Interpreting, Stephanie Jo Kent

Doctoral Dissertations

What do community interpreting for the Deaf in western societies, conference interpreting for the European Parliament, and language brokering in international management have in common? Academic research and professional training have historically emphasized the linguistic and cognitive challenges of interpreting, neglecting or ignoring the social aspects that structure communication. All forms of interpreting are inherently social; they involve relationships among at least three people and two languages. The contexts explored here, American Sign Language/English interpreting and spoken language interpreting within the European Parliament, show that simultaneous interpreting involves attitudes, norms and values about intercultural communication that overemphasize information and discount …

Community Development In Emerging Cities: A Case For Lagos,Nigeria, Olaoluwa Olakunle Silva

Masters Theses

Urban spatial expansion resulting from urbanization in Sub-Saharan Africa (SSA) is growing and will not stabilize in the near future. Sub-Saharan Africa’s urban growth rate is climbing faster than developing economies. Efforts should be concentrated on accommodating this phenomenon through the promotion of sustainable urban planning and development.

Relying on secondary data, this research examines models of indigenous Sub-Saharan African urban forms and residential architecture vernacular to understand these forms and their characteristics, and how these models and associated management, design, and planning principles can be adopted in a contemporary context. Also, studies of established indigenous building materials and technology, …

Seeds Of A New Economy? A Qualitative Investigation Of Diverse Economic Practices Within Community Supported Agriculture And Community Supported Enterprise, Ted White

Open Access Dissertations

Amidst widespread feelings that capitalism is a deeply problematic yet necessary approach to economy, Community Supported Agriculture (CSA) has emerged as both an alternative model for farming and as an increasingly visible and viable model for alternative economy. Using qualitative methods, this doctoral research explores and documents how CSA has become a productive space for economic innovation and practice that emphasizes interdependence, camaraderie and community well-being rather than hierarchical control and private gain. This study also examines how the many participants of CSA have built an identity for CSA--branding it via autonomous and collective efforts. This has resulted in CSA …

Place And The Politics Of Knowledge In Rural Bolivia: A Postcoloniality Of Development, Ecology, And Well-Being, Karen Marie Lennon

Open Access Dissertations

This dissertation is a study of the dynamics of place and people in a rural municipality in southeastern Bolivia. A study of the dialectical relations between knowledge, ecology, and culture that are manifest through the daily life of the municipality, it is an ethnography that illuminates the multiple discourses of colonialism, nationalism, modernity and decolonization that overlay one another. The contradictions and tensions produced through these intersecting discourses represent major obstacles to the project of "decolonization" and the formation of viable and equitable "intercultural" relationships, as promoted by the indigenous leadership which is the governing party of the Bolivian state …

The Role Of Prompts As Focus On Form On Uptake, Brian Bates Boisvert

Open Access Dissertations

Students are human beings; they, like all of us, make mistakes. In the language classroom, these mistakes may be written, spoken, and even thought. How, if, when, under what conditions and to what degree these errors are treated is of current concern in research regarding language acquisition. In their meta-analysis of interactional feedback, Mackey and Goo (2007) report that the utilization of feedback is beneficial and find evidence that feedback within the context of a focus on form environment is also facilitative of acquisition, echoing Norris and Ortega's (2000) positive findings regarding focus on form research. Thus, the role of …

Youth And Economic Development: A Case Study Of Out-Of-School Time Programs For Low-Income Youth In New York State, Kristen Maeve Powlick

Open Access Dissertations

Children are conceptualized many ways by economists-- as sources of utility for their parents, investments, recipients of care, and public goods. Despite the understanding that children are also people, the economic literature is lacking in analysis of children as actors, making choices with consequences for economic development. Using a capability-driven approach and an emphasis on co-evolutionary processes of institutional and individual change, with mixed qualitative and quantitative methods, my dissertation analyzes the role of children in long-term economic development at the community level. I use a case study of community-based, out-of-school time (OST) programs for low-income youth funded through the …

Why China Grew: Understanding The Financial Structure Of Late Development, Adam S. Hersh

Open Access Dissertations

This dissertation explores how economic institutions governing finance and investment have con- tributed to growth in reform-era China. Economic and political reforms greatly transformed China's prior centrally-planned economy. Although reforms incorporated elements of market institutions and private enterprise, China's state institutions exercising extensive authority over a wide range of eco- nomic affairs critically and fundamentally played a central role in transforming this economy from one of the world's poorest to the world's second largest in the span of one generation. I explain the emergence of a unique configuration of institutions supportive of industrial policy implemented by largely autonomous local government …

Piping Plover (Charadrius Melodius) Conservation On The Barrier Islands Of New York: Habitat Quality And Implications In A Changing Climate, Jennifer Ruth Seavey

Open Access Dissertations

Habitat loss is the leading cause of species extinction. Protecting and managing habitat quality is vital to an organism's persistence, and essential to endangered species recovery. We conducted an investigation of habitat quality and potential impacts from climate change to piping plovers (Charadrius melodius) breeding on the barrier island ecosystem of New York, during 2003-2005. Our first step in this analysis was to examined the relationship between two common measures of habitat quality: density and productivity (Chapter 1). We used both central and limiting tendency data analysis to find that density significantly limited productivity across many spatial scales, especially broader …
