Description
There is a documented gap between research-based recommendations produced by university-based scholars in the field of education in the United States and the evidence that U.S. politicians' use when deciding which educational policies to implement or amend. This is a problem because university-based education scholars produce vast quantities of research each year, some of which could, and more importantly should, be useful to politicians in their decision-making processes and yet, politicians continue to make policy decisions about education without the benefit of much of the knowledge that has been gained through scholarly research. I refer to the small fraction of university-based education scholars who are demonstrably successful at getting scholarly research into the hands of politicians to be used for decision-making purposes as "university-based bipartisan scholarship brokers". They are distinct from other university-based education scholars in that they engage with politicians from both political parties around research and, as such, are able to use scholarly research to influence the education policymaking process. The problem that this dissertation addresses is the lack of use, by U.S. politicians, of scholarly research produced by United States university-based education scholars as input in education policy decisions. The way in which this problem is explored is through studying university-based bipartisan scholarship brokers. I focused on three areas for exploration: the methods university-based bipartisan scholarship brokers use to successfully get U.S. politicians to consider scholarly research as an input in their decision-making processes around education policy, how these scholars are different than the majority of university-based education policy scholars, and how they conceive of the education policy-setting agenda. What I uncovered in this dissertation is that university-based bipartisan scholarship brokers are a complete sub-group of university-based education scholars. They work above the rigorous promotion and tenure requirements of their home universities in order to use scholarly research to help serve the research needs of politicians. Their engagement is distinct among university-based education scholars and through this dissertation their perspective is presented in participants' own authentic language.

Description
What does it mean to speak of governance in the absence of states? This dissertation seeks to answer this question through an empirical examination of the founding of two unique agricultural settlements constructed by the Jewish community of Palestine, also known as the Yishuv: the kibbutz and the moshav. Commonly, in order to be considered effective, states must, at minimum, provide their population with two critical public goods: the satisfaction of their material needs and their physical protection through a military or police force. Dominant assumptions across multiple subfields of both Comparative Politics and International Relations content that because weak and failed states cannot provide their civilian populations with these critical public goods, that governance in the absence of effective, sovereign, and territorial states is a myth. It is often argued that violence, anarchy, and human suffering inevitably follow in the wake of state collapse and that in order to alleviate these problems, state building practices must focus on creating a fully sovereign state that has a monopoly on the legitimate use of violence within its borders. This dissertation questions these assumptions. Through quantitative analysis of an original dataset constructed from Israeli archival sources as well as a qualitative historical examination of declassified Israeli archival material from 1920-1948, this dissertation demonstrates that it is possible for non-state actors to construct institutions of governance within the context of a weak or failing state. The Jewish community, through its organs of governance, utilized the kibbutzim and the moshavim to provide the all important public goods of military defense and economic growth respectively. It is shown in this dissertation how political institutions can be crafted endogenously within weak and failing states and how these institutions may actually serve to increase political stability, staving off anarchy and violence.

Description
Traditional approaches to modeling microgrids include the behavior of each inverter operating in a particular network configuration and at a particular operating point. Such models quickly become computationally intensive for large systems. Similarly, traditional approaches to control do not use advanced methodologies and suffer from poor performance and limited operating range. In this document a linear model is derived for an inverter connected to the Thevenin equivalent of a microgrid. This model is then compared to a nonlinear simulation model and analyzed using the open and closed loop systems in both the time and frequency domains. The modeling error is quantified with emphasis on its use for controller design purposes. Control design examples are given using a Glover McFarlane controller, gain sched- uled Glover McFarlane controller, and bumpless transfer controller which are compared to the standard droop control approach. These examples serve as a guide to illustrate the use of multi-variable modeling techniques in the context of robust controller design and show that gain scheduled MIMO control techniques can extend the operating range of a microgrid. A hardware implementation is used to compare constant gain droop controllers with Glover McFarlane controllers and shows a clear advantage of the Glover McFarlane approach.

Description
Gender and sex are often conflated. Our laws, policies, and even science establish sex and gender as intrinsically linked and dimorphic in nature. This dissertation examines the relationship between sex and gender and the repercussions of this linked dimorphism in the realms of law, politics, and science. Chapter One identifies the legal climate for changing one's sexual identity post-surgical reassignment. It pays particular attention to the ability of postsurgical transsexuals to marry in their acquired sex. Chapter Two considers the process for identifying the sex of athletes for the purposes of participation in sex-segregated athletic events, specifically the role of testing and standards for categorization. Chapter Three explores the process of identifying and assigning the sex of intersex children. Chapter Four examines the process of prenatal sex selection and its ethical implications. Chapter Four also offers an anticipatory governance framework to address these implications.

Description
This research conducts two methods of rhetorical analysis of State of the Union Addresses: 1. Computational linguistic analysis of all State of the Union Addresses from 1790-2007, and 2. Close-readings and rhetorical analyses of two addresses: one by President Truman and one by President Reagan. This research shows the following key findings: 1. I am able to see general shifts in the authors' approaches to the State of the Union Address through historical computational analyses of the content of all speeches, and 2. Through close readings, I can understand the impact of the author's ethos and the historical context on the addresses, something that would not be readily revealed in a computational analysis. This study starts with a historical computational linguistic analysis of all State of the Union Addresses between 1790 and 2007. The study follows with close-readings of two State of the Union Addresses from the early and late Cold War period in-context: 1. Harry Truman's 1951 Address and 2. Ronald Reagan's 1986 Address. The main conclusions drawn from this research are that close-readings of State of the Union Addresses cannot be replaced by computational analyses, but can work in tandem with computerized text analysis to reveal shifts in rhetorical and topical features. This paper argues that there must be more close analyses in coordination with large-scale text analysis in order to understand the complexities of rhetorical situations.

Description
The object of this study was a 26 year old residential Photovoltaic (PV) monocrystalline silicon (c-Si) power plant, called Solar One, built by developer John F. Long in Phoenix, Arizona (a hot-dry field condition). The task for Arizona State University Photovoltaic Reliability Laboratory (ASU-PRL) graduate students was to evaluate the power plant through visual inspection, electrical performance, and infrared thermography. The purpose of this evaluation was to measure and understand the extent of degradation to the system along with the identification of the failure modes in this hot-dry climatic condition. This 4000 module bipolar system was originally installed with a 200 kW DC output of PV array (17 degree fixed tilt) and an AC output of 175 kVA. The system was shown to degrade approximately at a rate of 2.3% per year with no apparent potential induced degradation (PID) effect. The power plant is made of two arrays, the north array and the south array. Due to a limited time frame to execute this large project, this work was performed by two masters students (Jonathan Belmont and Kolapo Olakonu) and the test results are presented in two masters theses. This thesis presents the results obtained on the north array and the other thesis presents the results obtained on the south array. The resulting study showed that PV module design, array configuration, vandalism, installation methods and Arizona environmental conditions have had an effect on this system's longevity and reliability. Ultimately, encapsulation browning, higher series resistance (potentially due to solder bond fatigue) and non-cell interconnect ribbon breakages outside the modules were determined to be the primary causes for the power loss.

Description
Why do religious organizations facilitate secular political activism in some settings and not others? This dissertation uses regional variation in political activism across Mexico to elucidate the relationship between religious organizations and political activism, as measured through associational activity and involvement in political protests. I utilize a quantitative analysis of 13,500 data observations collected from the nationally representative National Survey of Political Culture and Citizenship (ENCUP), supplemented by municipal and diocesan-level data from a variety of governmental and Church statistical databases, to test several theories describing religion's potential impact on political activism. I also utilize a qualitative comparative analysis examining the relationship between the Catholic Church and political mobilization in the Mexican States of Chiapas, Morelos, and Yucatán. I present an agent-based model developed to delineate the micro-level mechanisms linking Church institutional configurations and religion's pro-social effects to individual incentives to politically organize. The predictions of the agent-based model are assessed against my statistical dataset. The study finds where religious institutions devolve decision-making, monitoring, and sanctioning authority to the laity, individuals develop capacities to overcome collective action problems related to political activism. Religious ideology is also found to influence capacities for political activism.

Description
Energy is a central concern of sustainability because how we produce and consume energy affects society, economy, and the environment. Sustainability scientists are interested in energy transitions away from fossil fuels because they are nonrenewable, increasingly expensive, have adverse health effects, and may be the main driver of climate change. They see an opportunity for developing countries to avoid the negative consequences fossil-fuel-based energy systems, and also to increase resilience, by leap-frogging-over the centralized energy grid systems that dominate the developed world. Energy transitions pose both challenges and opportunities. Obstacles to transitions include 1) an existing, centralized, complex energy-grid system, whose function is invisible to most users, 2) coordination and collective-action problems that are path dependent, and 3) difficulty in scaling up RE technologies. Because energy transitions rely on technological and social innovations, I am interested in how institutional factors can be leveraged to surmount these obstacles. The overarching question that underlies my research is: What constellation of institutional, biophysical, and social factors are essential for an energy transition? My objective is to derive a set of "design principles," that I term institutional drivers, for energy transitions analogous to Ostrom's institutional design principles. My dissertation research will analyze energy transitions using two approaches: applying the Institutional Analysis and Development Framework and a comparative case study analysis comprised of both primary and secondary sources. This dissertation includes: 1) an analysis of the world's energy portfolio; 2) a case study analysis of five countries; 3) a description of the institutional factors likely to promote a transition to renewable-energy use; and 4) an in-depth case study of Thailand's progress in replacing nonrenewable energy sources with renewable energy sources. My research will contribute to our understanding of how energy transitions at different scales can be accomplished in developing countries and what it takes for innovation to spread in a society.

Description
The purpose of this dissertation is to study not only relations between Latin America and the United States, but also Latin American states with each other. It specifically aims to examine the extent to which the United States, the principal hegemonic power in the Americas, can play a constructive role by providing regional public goods. These goods include conflict resolution and economic progress. Although the United States has the potential to create such goods, it also has the potential to create public bads in the form of regional instability, political terror, and economic stagnation. This raises two fundamental research questions: Under what conditions can Washington play a positive role and if these conditions cannot be met, under what conditions can Latin American nations bypass the United States and create their own economic progress and conflict resolution strategies? Drawing upon qualitative research methods and case studies that have attracted scant academic attention, this dissertation finds that through regional multilateral diplomatic negotiations, the United States can play a positive role. However, due to U.S. parochial economic interests and the marginalization of diplomacy as a foreign policy tool, these conditions rarely occur. This research further finds, however, that through flexible regionalization Latin American nations can bypass the United States and create their own goods. Supported by an alternative regional power, flexible regionalization relies upon supranational institutions that exclude the United States, emphasize permanent political and economic integration, and avoid inflexible monetary unions. Through this type of regionalization, Latin America can decrease U.S. interference, sustain political and economic autonomy, and open space for alternative conflict resolution strategies and economic policies that Washington would otherwise oppose. This dissertation is academically significant and policy relevant. First, it reconsiders diplomacy as an instrumental variable for peace and offers generalizable results that can be applied to additional cases. Moreover, finding that Latin American countries can address their own regional issues, this study recognizes the positive agency of Latin America and counters the negative essentialization commonly found in U.S. academic and policy research. Finally, this research offers policy advice for both the United States and Latin America.

Description
Dye sensitized solar cells (DSSCs) are currently being explored as a cheaper alternative to the more common silicon (Si) solar cell technology. In addition to the cost advantages, DSSCs show good performance in low light conditions and are not sensitive to varying angles of incident light like traditional Si cells. One of the major challenges facing DSSCs is loss of the liquid electrolyte, through evaporation or leakage, which lowers stability and leads to increased degradation. Current research with solid-state and quasi-solid DSSCs has shown success regarding a reduction of electrolyte loss, but at a cost of lower conversion efficiency output. The research work presented in this paper focuses on the effects of using nanoclay material as a gelator in the electrolyte of the DSSC. The data showed that the quasi-solid cells are more stable than their liquid electrolyte counterparts, and achieved equal or better I-V characteristics. The quasi-solid cells were fabricated with a gel electrolyte that was prepared by adding 7 wt% of Nanoclay, Nanomer® (1.31PS, montmorillonite clay surface modified with 15-35% octadecylamine and 0.5-5 wt% aminopropyltriethoxysilane, Aldrich) to the iodide/triiodide liquid electrolyte, (Iodolyte AN-50, Solaronix). Various gel concentrations were tested in order to find the optimal ratio of nanoclay to liquid. The gel electrolyte made with 7 wt% nanoclay was more viscous, but still thin enough to allow injection with a standard syringe. Batches of cells were fabricated with both liquid and gel electrolyte and were evaluated at STC conditions (25°C, 100 mW/cm2) over time. The gel cells achieved efficiencies as high as 9.18% compared to 9.65% achieved by the liquid cells. After 10 days, the liquid cell decreased to 1.75%, less than 20% of its maximum efficiency. By contrast, the gel cell's efficiency increased for two weeks, and did not decrease to 20% of maximum efficiency until 45 days. After several measurements, the liquid cells showed visible signs of leakage through the sealant, whereas the gel cells did not. This resistance to leakage likely contributed to the improved performance of the quasi-solid cells over time, and is a significant advantage over liquid electrolyte DSSCs.
