- Understanding the changes in molecular electronic structure following the absorption of light is a fundamental challenge for the goal of predicting photochemical rates and mechanisms. Proposed here is a systematic benchmarking method to evaluate accuracy of a model to quantitatively predict photo-degradation of small organic molecules in aquatic environments. An overview of underlying com- putational theories relevant to understanding sunlight-driven electronic processes in organic pollutants is presented. To evaluate the optimum size of solvent sphere, molecular Dynamics and Time Dependent Density Functional Theory (MD-TD-DFT) calculations of an aniline molecule in di↵erent numbers of water molecules using CAM-B3LYP functional yielded excited state energy and oscillator strength values, which were compared with data from experimental absorption spectra. For the first time, a statistical method of comparing experimental and theoretical data is proposed. Underlying Gaussian functions of absorption spectra were deconvoluted and integrated to calculate experimental oscillator strengths. A Matlab code written by Soren Eustis was utilized to decluster MD-TD-DFT results. The model with 256 water molecules was decided to give the most accurate results with optimized com- putational cost and accuracy. MD-TD-DFT calculations were then performed on aniline, 3-F-aniline, 4-F-aniline, 3-Cl-aniline, 4-MeOacetophenone, and (1,3)-dimethoxybenzophenone with CAM-B3LYP, PBE0, M06-2X, LCBLYP, and BP86 functionals. BP86 functional was determined to be the best functional. Github repository: https://github.com/eustislab/MD_Scripts

- How can individuals in the contemporary media and political environment form better political beliefs? In chapter one, this thesis considers what it means to say American politics is polarized. It evaluates the extent of polarization in American politics. And it presents original evidence that suggests that just as the public and members of Congress have polarized, so too has American political discourse. Through the lens of political psychology, chapter two investigates how America’s polarized politics has influenced the quality of individuals’ beliefs. Chapter three explores the role that the media plays in encouraging or minimizing the biased information processing practices identified in chapter two. Finally, I conclude by arguing that individuals need to fundamentally rethink how they consume political information; advocate for the creation of a completely new social media platform specifically designed to encourage political deliberation; and outline what such a platform might look like.

- Site-specific recombinases (SSRs) are valuable tools for manipulating genomes. In Drosophila, thousands of transgenic insertions carrying SSR recognition sites have been distributed throughout the genome by several large-scale projects. Here we describe a method with the potential to use these insertions to make custom alterations to the Drosophila genome in vivo. Specifically, by employing recombineering techniques and a dual recombinase-mediated cassette exchange strategy based on the phiC31 integrase and FLP recombinase, we show that a large genomic segment that lies between two SSR recognition-site insertions can be "captured" as a target cassette and exchanged for a sequence that was engineered in bacterial cells. We demonstrate this approach by targeting a 50-kb segment spanning the tsh gene, replacing the existing segment with corresponding recombineered sequences through simple and efficient manipulations. Given the high density of SSR recognition-site insertions in Drosophila, our method affords a straightforward and highly efficient approach to explore gene function in situ for a substantial portion of the Drosophila genome. © 2013 by the Genetics Society of America.

Biographial Note
Kent Conrad was born on March 12, 1948, in Bismarck, North Dakota, to Abigail and Gaylord Conrad. After graduating from Phillips Exeter Academy in 1966, he attended Stanford University; he later received an MBA from George Washington University. After college, Conrad became an assistant to the North Dakota tax commissioner. He became tax commissioner in 1980, a job he held until 1986, when he successfully ran for the Senate as a Democrat representing North Dakota, when George Mitchell was chair of the DSCC. In 1992, he chose not run for reelection because of a campaign promise he made that he would not run for reelection if the budget deficit had not fallen by the end of his first term. However, the other North Dakota Senate seat became vacant and Conrad won a special election to fill that vacancy in December of 1992. At the time of this interview he was still in the Senate, serving on the Finance Committee, the Committee on Agriculture, Nutrition and Forestry, the Joint Committee on Taxation, the Committee on Indian Affairs, and as chairman of the Budget Committee.
Summary
Interview includes discussions of: the Muskie presidential campaign; Conrad’s Senate campaign of 1986; Mitchell as chair of the Democratic Senatorial Campaign Committee and his decision to give the maximum possible support to Conrad; the Clean Air Act; North Dakota’s interest as a coal state and the difficulties that posed for Conrad when Mitchell wanted him to get behind the Clean Air Act; Mitchell’s leadership qualities such as patience and determination; Mitchell’s role in balancing the budget under the Clinton administration; Mitchell’s skill in questioning witnesses; Mitchell’s sense of humor and how that served him well as a senator; Conrad’s recommendation to then Senator Obama regarding the importance of reaching out to Mitchell; and the prospects for Mitchell in his new post as special envoy to the Middle East.

David F. Durenberger was born August 19, 1934, in St. Cloud, Minnesota. He attended St. John’s University and the University of Minnesota Law School, graduating in 1959. Beginning in 1966, he was chief of staff to Minnesota Governor Harold LeVander. In 1978, he won a special election to finish the unexpired term of Senator Hubert Humphrey, was reelected twice, and held the seat until 1995. He served as chairman on the Select Committee on Intelligence, was vice chair of the Pepper Commission, and had a special interest in issues involving health care. At the time of this interview, he was a health policy fellow at the University of St. Thomas, and he sat on the advisory board for Energy Literacy Advocates.
