Session 2-3-F: Gaming Applications Of A Forgotten Distribution, Rohan J. Dalpatadu, Ashok K. Singh May 2013

Session 2-3-F: Gaming Applications Of A Forgotten Distribution, Rohan J. Dalpatadu, Ashok K. Singh

International Conference on Gambling & Risk Taking

Introduction

The bonus game has become a very important part of the slot machine, as indicated by a large number of patent applications and patents (Bennett, 2000; Slomiany and Grupp, 2000; Vancurra, 2000; Baerlocher et al, 2002; Jaffe et al, 2002; Cannon and Donovan, 2003; Dickerson, 2005). Therefore, probability distributions suitable for developing games are very much in need. In this study, we illustrate how a forgotten discrete probability distribution, viz. the negative hypergeometric distribution, can be used to develop bonus games for slot machines, and also to analyze existing bonus games. The mean and the variance for this distribution …

A variety of methods are often employed to forecast the outcome of sports events and to shed light upon the factors that influence contestants’ winning prospects. We explore the potential of combining forecasts to improve the accuracy of sports event prediction. Successful combination usually involves accurate and diverse individual predictions. Further, to accurately predict the outcome of sports events it is important to effectively account for the intensity of rivalry among contestants. Consequently, we develop modeling procedures and practices for addressing these challenges: First, in order to construct a large and diverse library of base models, we employ a range …

Mid-Morning Break And Poster Sessions: Comorbidity Among Pathological Gamblers Seeking Treatment, Daniela Gonzalez-Sicilia, Louise Nadeau May 2013

Mid-Morning Break And Poster Sessions: Comorbidity Among Pathological Gamblers Seeking Treatment, Daniela Gonzalez-Sicilia, Louise Nadeau

International Conference on Gambling & Risk Taking

Context of the study

Pathological gambling prevalence in the general population: United States 0.42% (Petry et al., 2005), Canada 0.5% (Rush et al., 2008), Quebec 0.7% (Kairouz et al., 2011)

Epidemiological surveys (i.e. NESARC) indicate that pathological gambling is usually accompanied by other comorbid disorders, such as: Alcohol and drug abuse (prevalence of 25 and 27%, respectively), alcohol and drug dependence (48 and 11%), mood disorders (50%), anxiety disorders (41%), personality disorders (61%). (Petry et al., 2005)

The comorbidity found in clinical samples is usually higher than that in the general population because it is more likely for a person …

Mid-Morning Break And Poster Sessions: A Comparative Analysis Of Design And Motivation In Slot Machines And Video Games, Daniel Sahl

International Conference on Gambling & Risk Taking

Introduction

The slot machines of today reflect an impressive design feat: translating cold win/loss probability into an unpredictable, whimsical, and engaging experience. A successful spin offers more than a quick payout, it’s an opportunity to experience hidden secrets within the machine: creative bonus games, rich animation and movie clips, even the chance to play simultaneously with other players on linked machines. Many of these characteristics are similar to design and gameplay elements of video games. Separate research into both slots and video games often reflect similar questions about design, motivation for play and addiction. This poster presents a visual and …

International Conference on Gambling & Risk Taking

While many governments are considering the option of legalizing online gambling, mental health professionals and public health advocates worry that it will increase the number of problem gamblers. Results of the survey show that 3% of the sample, composed of 1009 Internet users, intended to gamble real money on the new online legal site, 6% would gamble without money, and 5% would visit the new site without gambling. Nearly 45% of those who intended to visit the legal gambling site were Internet non-gamblers in the last year. Half of online gamblers intended to gamble on the new legal site. Also, …


Mid-Morning Break And Poster Sessions: Family Gambling And Its Connection To Intergenerational Family Relationship Building, Melissa M. Sleightholm, Joan E. Norris, Joseph Tindale May 2013

Mid-Morning Break And Poster Sessions: Family Gambling And Its Connection To Intergenerational Family Relationship Building, Melissa M. Sleightholm, Joan E. Norris, Joseph Tindale

International Conference on Gambling & Risk Taking

Introduction

Most research has viewed gambling as an individual activity and very little research has been devoted to the impacts of family gambling.

Bengtson and Roberts (1991) viewed intergenerational family solidarity as a comprehensive construct consisting of six components of solidarity. Affectual, Associational, and Functional solidarities, can be adapted to a gambling context.

The three family solidarity dimensions of affection, association, and function are the core components to family solidarity (Hogerbrugge & Komter, 2012).

What do we know about risk factors for PG?

Vast majority of research carried out on PG risk factors has involved cross-sectional surveys

PG status at a single point in time statistically correlated with behaviors & characteristics assessed at the same time

Cannot resolve the “chicken and egg” problem

  • Does PG precede other disorders?
  • Do other disorders precede PG?
  • Or does one underlying condition account for both?

Session 1-4-B: Gambling And Marijuana Use In The Netherlands: Is Legalization The Best Tool For Dealing With "Naughty Habits?", William N. Thompson, Laura K. Thompson

International Conference on Gambling & Risk Taking

In 1976, the Netherlands embraced two policy initiatives which encompassed similar objectives. The policies sought to control “undesired substances” via the process of legalization. One legalization process involved casino gambling. The policies have sometimes led to desired results (the right road), while at other times they have led to undesirable results (the wrong road). Now in 2013, without an observable crossroad or even fork in the road, The Netherlands is poised to deviate from a right road to travel down a wrong road by placing rather severe restrictions upon the operations of “Coffee Houses” which have been “serving” customers measured …

Session 1-2-F: Rationality And Risk Intelligence In Binary Betting, Raph Di Guisto, Aaron C. Brown, Nick Maughan

International Conference on Gambling & Risk Taking

We analyze 1.6 million binary bets on financial markets totaling $600 million in stakes, placed by 21,000 bettors at a large Internet betting site. The data set is unusually large and complete, plus has one additional important advantage: we can obtain objective independent estimates of the ex ante probability of winning each bet, using data from financial markets. This allows us to distinguish bettor profit due to superior prediction of financial events from bettor profit due to exploiting ex ante favorable odds situations. We focus on the degree or type of skill possessed by bettors (if any), and the amount …

Fearless: Kevin Lugo, Kevin B. Lugo

SURGE

This summer, recent graduate Kevin Lugo will bike over 4,000 miles across the country to benefit the Ulman Cancer Fund for Young Adults. His choice to bike for seventy days from Baltimore to Seattle makes him fearless! His goal is to raise $7,476 for the organization, and he reached that goal last night (although more donations are always welcome in support of fighting cancer)! Kevin explains that when he studied abroad in Denmark in the fall of 2011, he “fell in love with sustainable transportation, especially cycling.” Not only does his fearless endeavor raise money to fight cancer, but he …

Pilot Comparative Effectiveness Study Of Surface Perturbation Treadmill Training To Prevent Falls In Older Adults, Jon D. Lurie, Alexandra B. Zagaria, Dawna M. Pidgeon, Judith L. Forman, Kevin Spratt May 2013

Pilot Comparative Effectiveness Study Of Surface Perturbation Treadmill Training To Prevent Falls In Older Adults, Jon D. Lurie, Alexandra B. Zagaria, Dawna M. Pidgeon, Judith L. Forman, Kevin Spratt

Dartmouth Scholarship

Falls are the leading cause of fatal and non-fatal injuries among older adults. Exercise programs appear to reduce fall risk, but the optimal type, frequency, and duration of exercise is unknown. External perturbations such as tripping and slipping are a major contributor to falls, and task-specific perturbation training to enhance dynamic stability has emerged as a promising approach to modifying fall risk. The purpose of this pilot study was 1) to determine the feasibility of conducting a large pragmatic randomized trial comparing a multidimensional exercise program inclusive of the surface perturbation treadmill training (SPTT) to multidimensional exercise alone (Standard PT); …

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

Dual pH and temperature sensitive microgel-based etalons were fabricated by sandwiching a “monolithic” microgel layer between two semitransparent, Au layers. The devices exhibit visual color and multipeak reflectance spectra, both of which primarily depend on the distance between the Au surfaces mediated by the microgel diameter. We found that a polycationic polyelectrolyte can penetrate through the Au overlayer to interact with negatively charged microgel confined between Au overlayers. In this submission we report that biotinylated polycationic polymer can penetrate through the Au overlayer of a poly (N-isopropylacrylamide)-co-acrylic acid (pNIPAm-co-AAc) microgel-based etalon and cause the microgel layer to collapse. The collapse …


Estimating Effects On Rare Outcomes: Knowledge Is Power, Laura B. Balzer, Mark J. Van Der Laan May 2013

Estimating Effects On Rare Outcomes: Knowledge Is Power, Laura B. Balzer, Mark J. Van Der Laan

U.C. Berkeley Division of Biostatistics Working Paper Series

Many of the secondary outcomes in observational studies and randomized trials are rare. Methods for estimating causal effects and associations with rare outcomes, however, are limited, and this represents a missed opportunity for investigation. In this article, we construct a new targeted minimum loss-based estimator (TMLE) for the effect of an exposure or treatment on a rare outcome. We focus on the causal risk difference and statistical models incorporating bounds on the conditional risk of the outcome, given the exposure and covariates. By construction, the proposed estimator constrains the predicted outcomes to respect this model knowledge. Theoretically, this bounding provides …
