Melanoma is one of the most severe forms of skin cancer and can be life-threatening due to metastasis if not caught early on in its development. Over the past decade, the U.S. Government added a Healthy People 2020 objective to reduce the melanoma skin cancer rate in the U.S. population. Now that the decade has come to a close, this research investigates possible large-scale risk factors that could lead to incidence of melanoma in the population using logistic regression and propensity score matching. Logistic regression results showed that Caucasians are 14.765 times more likely to get melanoma compared to non-Caucasians; however, after adjustment using propensity scoring, this value was adjusted to 11.605 times more likely for Caucasians than non-Caucasians. Cholesterol, Chronic Obstructive Pulmonary Disease, and Hypertension predictors also showed significance in the initial logistic regression. By using the results found in this experiment, the door has been opened for further analysis of larger-scale predictors and gives public health programs the initial information needed to create successful skin safety advocacy plans.

The current model of revenue generation for some free to play video games is preventing the companies controlling them from growing, but with a few changes in approach these issues could be alleviated. A new style of video games, called a MOBA (Massive Online Battle Arena) has emerged in the past few years bringing with it a new style of generating wealth. Contrary to past gaming models, where users must either purchase the game outright, view advertisements, or purchase items to gain a competitive advantage, MOBAs require no payment of any kind. These are free to play computer games that provides users with all the tools necessary to compete with anyone free of charge; no advantages can be purchased in this game. This leaves the only way for users to provide money to the company through optional purchases of purely aesthetic items, only to be purchased if the buyer wishes to see their character in a different set of attire. The genre’s best in show—called League of Legends, or LOL—has spearheaded this method of revenue-generation. Fortunately for LOL, its level of popularity has reached levels never seen in video games: the world championships had more viewers than game 7 of the NBA Finals (Dorsey). The player base alone is enough to keep the company afloat currently, but the fact that they only convert 3.75% of the players into revenue is alarming. Each player brings the company an average of $1.32, or 30% of what some other free to play games earn per user (Comparing MMO). It is this low per player income that has caused Riot Games, the developer of LOL, to state that their e-sports division is not currently profitable. To resolve this issue, LOL must take on a more aggressive marketing plan. Advertisements for the NBA Finals cost $460,000 for 30 seconds, and LOL should aim for ads in this range (Lombardo). With an average of 3 million people logged on at any time, 90% of the players being male and 85% being between the ages of 16 and 30, advertising via this game would appeal to many companies, making a deal easy to strike (LOL infographic 2012). The idea also appeals to players: 81% of players surveyed said that an advertisement on the client that allows for the option to place an order would improve or not impact their experience. Moving forward with this, the gaming client would be updated to contain both an option to order pizza and an advertisement for Mountain Dew. This type of advertising was determined based on community responses through a sequence of survey questions. These small adjustments to the game would allow LOL to generate enough income for Riot Games to expand into other areas of the e-sports industry.

Along with the number of technologies that have been introduced over a few years ago, gesture-based human-computer interactions are becoming the new phase in encompassing the creativity and abilities for users to communicate and interact with devices. Because of how the nature of defining free-space gestures influence user's preference and the length of usability of gesture-driven devices, defined low-stress and intuitive gestures for users to interact with gesture recognition systems are necessary to consider. To measure stress, a Galvanic Skin Response instrument was used as a primary indicator, which provided evidence of the relationship between stress and intuitive gestures, as well as user preferences towards certain tasks and gestures during performance. Fifteen participants engaged in creating and performing their own gestures for specified tasks that would be required during the use of free-space gesture-driven devices. The tasks include "activation of the display," scroll, page, selection, undo, and "return to main menu." They were also asked to repeat their gestures for around ten seconds each, which would give them time and further insight of how their gestures would be appropriate or not for them and any given task. Surveys were given at different time to the users: one after they had defined their gestures and another after they had repeated their gestures. In the surveys, they ranked their gestures based on comfort, intuition, and the ease of communication. Out of those user-ranked gestures, health-efficient gestures, given that the participants' rankings were based on comfort and intuition, were chosen in regards to the highest ranked gestures.

The purpose of this research is to identify the factors contributing the resiliency of Syria's President Assad amongst a backdrop of falling authoritarians during the Arab Spring. After determining the Assad's regime's strategies of authoritarian rule both before and after the 2011 uprisings, this paper theorizes what Assad's persistence is most dependent on today by analyzing his discourse throughout the conflict. Assad's framing of the war to the media has significantly legitimized his rule.

Description
The objective of this project concentrates on the game Defense of the Ancients 2 (Dota 2). In this game, players are constantly striving to improve their skills, which are fueled by the competitive nature of the game. The design influences the community to engage in this interaction as they play the game cooperatively. This thesis illustrates the importance of player interaction in influencing design as well as how imperative design is in affecting player interaction. These two concepts are not separate, but are deeply entwined. Every action performed within a game has to interact with some element of design. Both determine how games become defined as competitive, casual, or creative. Game designers can benefit from this study as it reinforces the basics of developing a game for players to interact with. However, it is impossible to predict exactly how players will react to a designed element. Designers should remember to tailor the game towards their audience, but also react and change the game depending on how players are using the elements of design. In addition, players should continue to push the boundaries of games to help designers adapt their product to their audience. If there is not constant communication between players and designers, games will not be tailored appropriately. Pushing the limits of a game benefits the players as well as the designers to make a more complete game. Designers do not solely create a game for the players. Rather, players design the game for themselves. Keywords: game design, player interaction, affinity space, emergent behavior, Dota 2

In 1972, the United States Supreme Court found that the death penalty was being applied too arbitrarily in the United States and that this arbitrary application constituted cruel and unusual punishment under the eighth amendment (Furman V. Georgia, 1972). This lead to a moratorium on capital punishment until the case Gregg V. Georgia, which outlined guidelines for the states in applying the death penalty in order to ensure that its application was constitutional (Gregg V. Georgia, 1976). These guidelines included enumerated aggravating factors and a bifurcated capital trial (Gregg V. Georgia, 1976). Despite these findings from the Supreme Court, the application of the death penalty in Arizona has remained problematic. In practice, Arizona has adopted a death penalty statute that appears to conform to the standards set by Furman and Gregg. Arizona state law includes a list of aggravating factors to help guide juries in capital trials and these trials are bifurcated. However, Arizona's aggravating factors are both numerous and inclusive, to the point that it is challenging to commit a first-degree murder in Arizona that does not include an aggravating factor. The statute fails to limit the crimes that qualify for the death penalty so state budgetary concerns become the limiting factor. Arizona's application of the death penalty remains arbitrary, in consistent, and as a result, unconstitutional as defined by the United States Supreme Court.

Bots tamper with social media networks by artificially inflating the popularity of certain topics. In this paper, we define what a bot is, we detail different motivations for bots, we describe previous work in bot detection and observation, and then we perform bot detection of our own. For our bot detection, we are interested in bots on Twitter that tweet Arabic extremist-like phrases. A testing dataset is collected using the honeypot method, and five different heuristics are measured for their effectiveness in detecting bots. The model underperformed, but we have laid the ground-work for a vastly untapped focus on bot detection: extremist ideal diffusion through bots.

Species survive by adapting to what is demanded by their environment. In constant and fluctuating environments, specialist and generalists should be favored, respectively. However, the costs and benefits of adaptation can depend on a variety of factors that alter the intensity of the specialist-generalist trade-off. We examined flight performance to determine how well flies that evolved in constant and fluctuating temperatures acclimated to hot and cold temperatures. We predicted that flies would perform best at temperatures most similar to the ones the flies evolved at. Best performance was found when rearing and testing temperatures aligned with the temperature at which a genotype had evolved, with the generalist sharing the best and worst performance combination with the constant thermally evolved flies. Interestingly, evolved and reared temperatures had equal impact on flight performance. It was also observed that rearing at 25°C resulted in flies with the best fitness. These results contribute to the specialist-generalist theory and the idea that long term cold development is restricting in terms of range for thermal performance.

Description
The Paradise Valley Family Resource Center (PVFRC) is a not for profit, community based organization funded by First Things First and a part of the Paradise Valley Unified School District (PVUSD) in Phoenix, Arizona. The mission of this organization is to connect and strengthen families with children from birth to five years old in the Phoenix valley. The PVFRC longed to be more cognizant of what the needs of the community they serve are, and how they, as an organization, can administer programs of value to the community. Hence, the PVFRC entered a partnership with the Community Action Research Experiences (CARE) program at Arizona State University to develop a research proposal to improve their effectiveness and efficiency at achieving their mission. The purpose of this research project was to identify and evaluate the needs of the families with children ages birth to five within the community, to improve upon existing programs and services or to implement new programs, and to discover more effective modes of awareness and advertisement to the community about the programs and services the PVFRC provides. The main research questions of the experiment included asking participants about what programs and services they need, wish, or want to exist at the PVFRC, what barriers or gaps they see or experience regarding attending the PVFRC, how did participants learn about the PVFRC, and what are the best ways to contact families in their community. The methods of the research included conducting focus group interviews with families who utilize the programs and services at the PVFRC and with early childhood professionals in the Paradise Valley Unified School District (PVUSD), which included social workers and preschool teachers. A total of 25 participants were interviewed (10 families, 6 social workers, and 9 preschool teachers) and responses from the interviews were coded by the researcher. The results of the research was that the PVFRC is meeting many needs and current families are satisfied, participants desire some changes to current programs and services, and the best modes of advertisement and awareness were "word of mouth" and the internet. It was recommended that in order to better achieve their mission, it is advised that the PVFRC make appropriate changes to programs and services as suggested by the participants, connect with mom's or parents groups in the community, collaborate with preschool teachers on the front line, and increase their online presence through the use of social media and their website.
