This dissertation consists of three essays on the identification analysis of econometric models.
The first essay explores the identification question in semiparametric binary response models when all regressors have discrete support. I suggest a recursive procedure that finds sharp bounds on the parameter of interest and can be applied to...
The authors of the article “Toward Environmentally Sustainable Digital Preservation” created this workshop as a space for participants to discuss issues of environmental sustainability in digital preservation, identify and enact change toward sustainable practices in their organizational contexts, and identify and plan further research. The workshop was run for the...
Aluminum alloys strengthened with coherent (L1<sub>2</sub>), nanosize Al<sub>3</sub>Sc precipitates may be used as structural materials at elevated temperatures. They are creep resistant at 300°C and exhibit a threshold stress, below which creep is not measurable. Introducing ternary alloying additions, such as rare-earth elements (RE=Y, Dy, Er), that segregate within Al<sub>3</sub>Sc...
This thesis presents results and analysis on a series of donor-bridge-acceptor (D-B-A) charge transfer systems in which we use time-resolved spectroscopy and magnetic resonance techniques to study the relationship of molecular structure to energy, charge, and spin transfer dynamics. We find that the sequence of events following the initial charge...
NiTi shape memory alloy (SMA) has drawn a great deal of attention for its various applications in the medical field (orthodontics, cardiovascular stents technology, etc.) and in other engineering fields (aerospace, aircraft, automotive, etc.) as it shows shape memory effect, superelasticity and biocompatibility. The fatigue-related issues, however, are pronounced in...
Bitcoin is a decentralized payment system proposed in 2008 by Nakamoto, who remains anonymous to date. It offers an effective alternative to fiat money or centralized payment systems with advantages on privacy, anonymity, and low international remittance fees. The transactions in Bitcoin payment system are sent through a peer-to-peer network,...
This manual describes use of a new hybrid autonomous crack and structural response monitoring (ACSM) system. It is designed as a low cost alternative to the research grade version employing SOMAT’s eDAQ data recording system. The concept is to combine a new field portable, 24 bit, 12 channel seismograph with...
Substance abuse is one of the most critical public health problems affecting juvenile detainees. Previous research suggests that a significant proportion of juvenile detainees with substance use disorders do not receive treatment prior to or during detention. Using data from the Northwestern Juvenile Project, a large-scale longitudinal study of juvenile...
Saccades are rapid eye movements that bring visual images into focus by placing them on the fovea. The control of accurate and precise saccades is essential for normal visual perception of the world around us. Disruptions in saccade production are the hallmark of several neurological disorders such as schizophrenia and...
The goal of this dissertation is to improve our understanding of the driving forces behind short-term movements in important aggregate variables such as exports, imports, the trade balance, output, investment, and employment. The first chapter contrasts the cyclical behavior of the trade balance and trade flows in a group of...
Researchers have long recognized that schools are powerful environments for shaping students' worldview and identity. The structured content, activities, and resultant culture of schools profoundly impact the way in which students learn to make sense of the world around them. In the ultra-Orthodox Jewish community this function of schooling is...
This project argues that displays of humanist learning in diplomacy served to demonstrate the extraordinary good will of the Florentine regime towards a host ruler. I call this act of surpassing previous oratorical gestures a "cultural gift". Although the singular goal of humanism in diplomacy remained offering cultural gifts in...
The small heat shock protein αB-crystallin is expressed primarily in lens and muscle tissue, but it is also found in lung, kidney and many cancers. Regulators of αB-crystallin have been identified almost exclusively using mouse muscle and lens specific models. It has been well documented that αB-crystallin is expressed in...
Recently, much public attention has been focused on racial inequalities in who is subjected to exclusionary school disciplinary policies, and consequently, forced to miss hours of instruction. Over the past two decades, researchers have documented the disparate impacts that zero-tolerance policies have had on students of color, low-income students, and...
Objective: To evaluate documentation of cardiovascular (CV) risk factors and obesity management by pediatric cardiologists. Study design: Review of medical records of obese (≥95th body mass index percentile) 2–17 year-old children presenting to outpatient pediatric cardiology over 1 year. Subjects were categorized as: heart disease (HD) with increased risk for...
This paper provides an overview of key governance issues of relevance to the upstream oil and gas industry in Canada. The focus is on implications of Canada's constitutional organization as a federation. Regulatory structures and provisions are described, as are revenue-sharing arrangements. Challenges for macro-economic management and for the environmental...
The past decade has witnessed exponential growth in study abroad participation. During these same years the promise that studying abroad will make students into Global Citizens has been a nearly ubiquitous feature in the promotion of the experience. Yet, Global Citizenship remains a highly contested concept that is rarely defined,...
This article examines how powerful policy actors defend themselves against opponents' strategies of conflict expansion through a case study of the Alberta oil sands subsystem. In response to changes in the key issues surrounding the oil sands subsystem, the provincial government along with industry have pursued a strategy of engaging...
This article challenges the role that successive generations of EU scholars have granted to the transnational networks of European federalists in the process of European integration. Whereas a first wave of scholarship has claimed that they played a huge role in the process (1) by convincing states to change their...
