Recent state legislation regulating fantasy sports contests may present a different type of threat to the nascent fantasy sports industry—the possibility that the U.S. Attorney General (or others) could invoke PASPA to enjoin the state law. This is the same law that prohibits states from legalizing traditional, single-game sports betting. Although PASPA has not yet surfaced as an obstacle to state legalization of DFS, it may emerge as an important issue as additional state legislative measures are introduced, particularly with a new U.S. Attorney General potentially taking a harder look at Internet gambling generally. Further, as more and more states begin passing laws legalizing daily fantasy sports contests, many have begun to question why some forms of sports gambling are allowed but not others. This chapter examines how PASPA could apply to state-sanctioned fantasy sports and provides an analytical framework for assessing the viability of such legislation under PASPA.

BACKGROUND: Autofluorescence imaging technology has been utilized for preserving or identifying parathyroid glands (PTGs) during thyroid surgery. We developed a wireless PTGs detection device linked with smart glasses that allows for real-time video recording and screen switching according to the light source. OBJECTIVE: This study aimed to confirm the feasibility of the device and whether it would help preserve the PTG during the surgery. METHODS: This prospective study was conducted in 30 patients with 66 PTGs. The device’s agreement with the physician’s judgment was evaluated, and we determined how many PTGs were preserved from thyroidectomy. RESULTS: The positive agreement rate for PTGs detection between the surgeon and device was 70.9%. Inadvertent parathyroidectomy was identified in surgical specimens of 6 patients (20%). No PTG was removed when it was confirmed by the device (0/39). Of the 27 glands not detected by the device, there was inadvertent removal of 6 PTGs. CONCLUSIONS: PTGs can be preserved successfully when the detection of them by the device is consistent with the surgeon’s discretion. A large-scale controlled study is necessary to demonstrate the practical effect of this device on hypoparathyroidism after thyroidectomy.

Differentiating and defining games of skill versus chance have major legal implications when classifying gambling, especially in relation to daily fantasy sports in the United States. This paper provides a theoretical discussion and introduces an empirical approach to analyzing game player pricing mechanisms. If game pricing mechanisms are fully efficient—player prices fully reflect the expected contributions from players—then that game is one of chance since there is no opportunity for skill to play a role in outcomes. This paper examines player prices from DraftKings’ daily fantasy football product. Empirical results show that there are strategies deriving from the pricing mechanism that can be incorporated by skilled participants to increase their expected performance and improve their chances of winning. This provides evidence that daily fantasy sports are skill-based—a necessary condition for skill to be a predominant factor in game outcomes as part of the legal debate.

AbstractThis paper outlines a novel approach to optimising teams for Daily Fantasy Sports (DFS) contests. To this end, we propose a number of new models and algorithms to solve the team formation problems posed by DFS. Specifically, we focus on the National Football League (NFL) and predict the performance of real-world players to form the optimal fantasy team using mixed-integer programming. We test our solutions using real-world data-sets from across four seasons (2014-2017). We highlight the advantage that can be gained from using our machine-based methods and show that our solutions outperform existing benchmarks, turning a profit in up to 81.3% of DFS game-weeks over a season.
