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, …

Breast Milk Stem Cells: Current Science And Implications For Preterm Infants, Carrie-Ellen Briere, Jacqueline M. Mcgrath, Todd Jensen, Adam Matson, Christine Finck

Elaine Marieb College of Nursing Faculty Publication Series

Background: The benefits of breast milk are well described, yet the mechanistic details related to how breast milk protects against acute and chronic diseases and optimizes neurodevelopment remain largely unknown. Recently, breast milk was found to contain stem cells that are thought to be involved in infant development.

Purpose: The purpose of this review was to synthesize all available research involving the characterization of breast milk stem cells to provide a basis of understanding for what is known and what still needs further exploration.

Methods/Search Strategy: The literature search was conducted between August and October 2015 using the CINAHL, PubMed, …
