In response to the increasing demands for mobile communications and differentiated network services, we present a novel and generalizable service architecture that supports multiple service classes in wireless networks with mobile hosts. This architecture, called Lottery-Based Multiple Access (LBMA), is based on the abstraction of a lottery, in which hosts hold lottery tickets that represent a ...

We examined the role of lottery participation in contributing to gambling-related problems, using a sample of 351 college students who self-identified as frequent gamblers, including a sub-sample of 133 frequent lottery gamblers. Participants completed the DSM-IV based Diagnostic Interview for Gambling Severity and two cognitive tasks, the Georgia Gambling Task (GGT) and the Iowa Gambling Task ...

Sunspot equilibrium and lottery equilibrium are two stochastic solution concepts for nonstochastic economies. We compare these concepts in a class of completely finite, (possibly) nonconvex exchange economies with perfect markets, which requires extending the lottery model to the finite case. Every equilibrium allocation of our lottery model is also a sunspot equilibrium allocation. The convers...

This paper proposes an electronic soccer lottery protocol suitable for the Internet environment. Recently, protocols based on public-key schemes such as digital signature have been proposed for electronic voting systems or other similar systems. For a soccer lottery system in particular, it is important to reduce the computational complexity and the amount of communication data required, becaus...

The study investigates the construct validity of a self-report questionnaire for dispositional sensitivity to befallen injustice (SBI; Schmitt, Neumann, & Montada, 1995). The items are combinations of four indicators of SBI (frequency of perceived injustice, intensity of anger, intrusiveness/perseverance of thoughts about the event, punitivity) with various types of unfair situations (e.g., per...

We investigate the impact of income distribution on lottery expenditures in Taiwan, using an agent-based model developed in [2, 3]. The agents in the model are potential lottery buyers, whose characteristics are described by three features: the percentage of income spent on the lottery, the preferences among lottery numbers selected and the aversion to regret. We used a genetic algorithm to dri...

When Jefferson introduced the state lottery to the United States, he hailed it as a voluntary tax that could entertain consumers while raising money for the government. However, by the late eighteen hundreds, the lottery was banned partly due to its reputation as a seedy, corrupt, and immoral system. Since being first reinstated by New Hampshire in 1954, the lottery has grown significantly, bei...

We characterize revenue maximizing head starts for all-pay auctions and lottery contests with many heterogeneous players. We show that under optimal head starts all-pay auctions revenue-dominate lottery contests for any degree of heterogeneity among players. Moreover, all-pay auctions with optimal head starts induce higher revenue than any multiplicatively biased all-pay auction or lottery cont...

Due to the mature of networks and communication technologies, electronic commerce is growing up rapidly and many advanced applications in electronic commerce have been developed recently, such as on-line shopping, on-line bidding, and on-line gambling. There are numerous types of gambling like typical lottery, sport lottery, and poker gambling. Our research will focus on the lottery games. Owin...
