Interview with Sean Davis
Interview with Sean Davis
Lucky Strike FTW (For the Win) arcade is a bowling alley and arcade located in downtown Chicago. With 130 games that give prizes every time, a mini golf course, pool tables, and bowling, it has something for everyone. Featuring fresh made food developed by an in-house chef, private suites overlooking the Chicago skyline, and a variety of party options, it’s a great experience. In charge of all of this is Sean Davis, the Director of Operations at Lucky Strike FTW. Mr. Davis has meddled in all areas of the entertainment business throughout his career, including working as a cook, waiter, bartender, manager, and general manager. He first discovered that he loved working in the entertainment industry when working as a local Massachusetts pizza maker, whose venue housed several bar games like billiards and its own mini golf course. He studied business at Northeastern University, and went on to work at Jillian’s arcade around 1993 in Boston, which featured 52 pool tables, 200 games, and 70,000 square feet of restaurant space. Then, in 2011 he started working at FTW in Chicago. As Director of Operations, Mr. Davis checks on things like making sure the arcade is staffed, ensuring each department has what they need, ordering, scheduling, and generally makes sure that everything in his arcade runs smoothly from day to day. However, as he’ll tell you, “There’s always something going on, there’s always a catastrophe... It’s never ‘Hey everything’s great,’” citing a time when a nearby pipe burst and caused the entire floor to flood, as one extreme case. Mr. Davis plays the games in his arcade as often as possible (his favorite game being Silent Scope), and loves watching other people enjoy themselves. He has said that some of his best days at work are when they bring in groups of less fortunate or handicapped children and let them play and have fun to their heart’s desire. Davis says that FTW is really a place for everyone. The arcade uses large cabinets and displays so that even adults can feel like a kid again when standing in front of the big games, part of the appeal to going to the arcade. “We serve great food, great beer. It really is like the total package. And it’s geared more towards adults than it is kids, because we do have a lot of adults saying, ‘Hey we’re going to bring our kids here,’ and they have their birthday parties here and kids love it. Typically the bigger arcades are more designed for kids and they have to bring their parents, and so we said well why don’t we make it for the parents, and they have to bring their kids. It seems to be working out.”

Crosslinking of Dermis-Derived Hydrogels Increases Stiffness and Alters Resistance to Degradation
Hydrogels have been investigated extensively as biomaterials for three-dimensional tissue reconstruction and regeneration. Incorporation of tissue-specific features into synthetic materials is difficult, due to limited ability to recreate the complex multi-component nature of extracellular matrices (ECM). ECM-rich hydrogels extracted and assembled from soft tissues have been shown to stimulate the formation of vascularized tissue in vitro and in vivo.1,2,3 Hydrogels derived from dermal tissue using this technique contain basement membrane proteins, including laminin 3, collagen IV, and collagen VII, all of which are essential for proper skin function.2 While these materials have significant biological activity, their poor mechanical properties and rapid degradation in vivo hinder their performance in wound healing applications. This study investigates the effect of covalent crosslinking on the mechanical properties, biological activity, and degradation (in vitro and in vivo) of dermal-derived hydrogels. Glutaraldehyde (GA) is a well-known crosslinking agent used in clinically approved products to prolong lifetime and increase strength of materials. Compression tests indicated increasing elastic modulus and yield stress of crosslinked hydrogels with crosslinking time (p<0.05). The crosslinked ECM were resistant to pepsin degradation in vitro. Gels and gel extracts were non toxic, and fibroblasts adhered and spread on gels at all crosslink densities. Crosslinking drastically slowed degradation relative to controls (non-crosslinked gels) in vivo in a subcutaneous implant model relative to control. While degradation was slowed, inflammation was low and mature vascularized tissue formed in the gels, suggesting that the materials retained the ability to induce tissue invasion. These results support the potential use of dermis-derived hydrogels as promising constructs for applications in tissue engineering and suggest that covalent crosslinking can be used to enhance mechanical properties and prolong hydrogel lifetime while inducing vascularized tissue formation., Based on this research, IIT biomedical engineering undergraduate senior Sophia Pilipchuk was named one of five recipients of the Biomedical Engineering Society (BMES) Undergraduate Student Award, to be presented in October 2011 at the BMES Annual Business Meeting in Hartford, Connecticut. Up to eight undergraduate students are selected from around the country on the basis of originality, significance, thoroughness of design analysis, and performance evaluation.
Raman Spectroscopy as a Probe of Surface Defects in Nb for SRF Cavities
Superconducting RF (SRF) cavities made of Nb are an enabling device for future linear accelerators. Recently it has been demonstrated that hot spots in SRF cavities, which diminish performance, are correlated with a high density of defects (etch pits) especially near grain boundaries. For a pit to cause local heating, it is likely that near-surface impurities, e.g. hydrides or oxides are leading to suppressed superconductivity. New probes are needed to measure such complexes. Here we present Raman spectroscopy. Raman is a fast, nonperturbative method that can measure the vibrational modes of Nb-O and Nb-H complexes by inelastic light scattering. These can then be compared to molecular dynamics simulations to identify oxide and hydride phases. The probing depth of Raman is estimated from the skin depth of the 785 nm laser in the bulk Nb ~ 10-20 nm. This is a reasonable fraction of the superconducting penetration depth ~ 45 nm. Simulating manufacturing processes of SRF cavities may shed light on the origins and composition of hot spots, and their relationship with defects in the material. Defects such as pits, whose origins are yet unknown, are found in the hot spots of completed cavities. Raman spectroscopy is used here to identify changes in the surface chemistry after manipulations such as creating artificial pits, exposing the material to chemical etching, or cold-working the material. BCP exposure and cold-working are common to the SRF manufacturing process.
Interview with Jim Zespy
Interview with Jim Zespy
Logan Arcade is a new arcade-bar that opened just February 2014. It features over twenty-five pinball machines and forty-five vintage arcade-games. Owner Jim Zespy collects and restores arcade games, including those in the arcade. His collection started in 2009; he seeks out games from the mid-1970s through the present. He often buys broken arcade machines and fixes them. Any machine that couldn't be fixed is as spare parts to maintenance other arcade machines. Zespy chooses games to be placed in the arcade based on the games’ popularity with the general public. He first balanced all different eras, and placed different kinds of games to try to have a balance. Afterward he watched to see which games people gravitated to, then took out the games people didn't like and placed more popular games. Zespy’s daily concern is the maintenance of the arcade machines. Logan Arcade has its own Local Pinball League, for which the game changes every week. While the league has scoring, and there is some competition, it's meant to encourage participants to play different games, get to know them, and get to know other people. Some players have made major records in the Logan Arcade. These records are on games including Nibbler, Tron Ice Score, and Tetris.
Interview with Terry Minnich and Jeff Lee
Interview with Terry Minnich and Jeff Lee
For our oral history project, we interviewed Jeff Lee, and Terry Minnich who is also known as Trickman Terry. Jeff Lee was an artist that made artwork for Q​­Bert, Exterminator,​ and as well as other freelancing work. Terry Minnich was an editor for a magazine called Electronic Gaming Monthly Magazine where he was an editor for the T​ips and Tricks s​ection where he would review tricks submitted from fans and publish them in EGM. Terry had a fairly large collection of arcade games in his basement which is where the interview took place. Both of these men were passionate about their job and were very knowledgeable in the video game industry. Terry Minnich worked many years as an editor for EGM, specifically the T​ricks and Tips section. He would receive letters from fans, receive information overseas from Japan, or play the games himself with his team to try to obtain tricks, cheats, glitches or bugs, and other information needed to make the games more enjoyable. Terry was also an avid collector who obtained and maintained a collection of arcade machines in his basement and was well informed in the hardware aspect of the history. Jeff Lee, the second person interviewed, was an artist who was a fan of video games, specifically at the bar scene where he would enjoy a few drinks along with playing P​inball o​r Armour Attack b​efore he got into the game industry in a more serious manner. He coincidently began working at G​ottlieb and Co.​as an artist where he made the artwork for Q​­bert​1, 2, and 3. Then him and a fellow partner from Q​­bert​were contracted to do some artistry work on a few games like E​xterminator. A​fter he finished his artwork for Q​­Bert, h​e did some freelancing, and did some art and design work for the games D​ouble Gs​and​Lotto Fun a​s well as another piece for the company​Credible Technologies. Terry Minnich, as part of his job as an editor, knew a lot about the Konami Code, which is a special combination of buttons the player can hit which will enable special abilities or extra lives. He mentioned the Konami Code as one of the first major cheat codes as it was used in many games such as G​radius, Contra, Dance Dance Revolution,​and other games. The Konami code was interesting to look at because it is something about the history that you can not find by looking at the game itself; you have to talk to the players and fans of the games to learn about. Jeff Lee was a major designer of Q*bert,a puzzle game where players had to make each color of a block on a pyramid the same color. This game was hugely popular and is considered to be a classic from its time period. Lee had significant contributions on the project including character design, using the pyramid shape as a game, and the “@​!#?@!” that the playable character would say in speech bubble. Minnich and Lee both had major impacts in the first generation of video games however from different positions. Lee was a creator and was part of the first hand industry while Minnich was part of the second hand industry that helped publicize the games and create the community of gamers that is around today. It is interesting to look at the multiple levels of the video game industry as there are many aspects to it like designing, manufacturing, retailing, the media scene, and the competition aspect.

Hashtag data from "Agenda Building & Indexing: Does the U.S. Congress Direct New York Times Content through Twitter?"
Hashtag data from "Agenda Building & Indexing: Does the U.S. Congress Direct New York Times Content through Twitter?"
From the paper: The conventional understanding of how elected officials affect the policy agenda is based in arguments that they use symbols and rhetoric to propagate the problem, and that this happens primarily through the traditional media. The arguments presented in this article are largely consistent with this but account for the function of social media. More specifically, and framed by indexing theory, we argue that social media enhances opportunities for policy agenda builders in the U.S. Congress to share information with journalists. Across the key policy issues of 2013, tests for congruence between politicians’ Twitter posts and New York Times articles confirm a connection, particularly for the policy issue areas of the economy, immigration, health care, and marginalized groups. Simultaneous discussion and debate between Democrats and Republicans about a particular policy issue area, however, negatively impacts how the New York Times indexes a particular issue., Here we provide single Excel file of all the hashtags posted by members of Congress to Twitter during 2013. The file contains three columns: datetime, hashtag, and twitter_username. The datetime indicates when a tweet was posted. The hashtag indicates what hashtag a user posted at that time (tweets may contain multiple tags). Twitter_username is the Twitter handle of the account that posted a tweet with that hashtag at that time. We created a list of member of Congress Twitter accounts by looking up each member and checking with Govtrack.us and congress.gov information. Please cite our paper: Shapiro, M. A. and Hemphill, L. (in press) Agenda Building & Indexing: Does the U.S. Congress Direct New York Times Content through Twitter? Policy & Internet.
Data used to develop #Polar scores
Data used to develop #Polar scores
We present a new approach to measuring political polarization, including a novel algorithm and open source Python code, which leverages Twitter content to produce measures of polarization for both users and hashtags. #Polar scores provide advantages over existing measures because they (1) can be calculated throughout the legislative cycle, (2) allow for easy differentiation between users with similar scores, (3) are chamber-agnostic, and (4) are a generic approach that can be applied beyond the U.S. Congress. #Polar scores leverage available information such as party labels, word frequency, and hashtags to create an accessible, straightforward algorithm for estimating polarity using text. (from the paper: Hemphill, L., Culotta, A., and Heston, M. (forthcoming) #Polar Scores: Measuring partisanship using social media content. Journal of Information Technology & Politics.), The dataset contains one plain text TSV file with the following information for each of the 55,244 tweets used to develop #Polar scores : tweet_id, created_at, user_id, screen_name, tag, shortid, sex, party, state, chamber, name. The file contains one row per hashtag, and therefore tweets may appear more than once. The Python code for calculating #Polar scores is available here: http://doi.org/10.5281/zenodo.53888
