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...
