Investigating Intermolecular Interactions In Crystalline Aspirin Using Cdft, Nicholas Turner, Tonglei Li, Mingtao Zhang

The Summer Undergraduate Research Fellowship (SURF) Symposium

Drugs today are widely administered in their crystalline form, namely via tablets and capsules. The crystal structure of a drug molecule affects important drug qualities such as solubility, bioavailability, shelf life, and compaction properties. In order to form a basis for crystal structure prediction, it is necessary to first understand how intermolecular interactions cause molecules to pack in certain ways. Being able to predict and perhaps even control a drug molecule’s crystal structure will lead to the development of higher quality drugs that perform more consistently. Scientists and engineers do not fully understand the reasons for a molecule assuming a …

Investigation Of Major Intermolecular Interactions In 7,8-Dihydrobenzo(K)Phenanthridin-6(5h)-One Crystal Using Quantum Calculations And Crystallographic Visualization Programs, Zhiwei Liao, Tonglei Li, Mingtao Zhang

The Summer Undergraduate Research Fellowship (SURF) Symposium

Currently, tablets and capsules are the most common ways of delivering drugs. The active pharmaceutical ingredients and excipients used to make those tablets and capsules are in their crystalline form generally. However, a single molecule can form multiple different crystal structures because of different packing arrangements of the molecules. These different crystal structures have identical chemical composition but different properties such as solubility, density, stability, etc. This phenomenon is called polymorphism. Occurrence of polymorphism could be a disaster for both patients and pharmaceutical companies, as the drug could lose its efficacy due to changes in properties. Studying intermolecular interactions in …

Session 4-1-D: The Experience Of Lotto 6/49 And The Capacity To Trust: Elements For An Anthropology Of Gambling, Jocelyn Gadbois

International Conference on Gambling & Risk Taking

Anthropologists study Lotto 6/49 as an experience.

Lévy-Bruhl tries to compare the magical beliefs of serious gamblers with the magical beliefs of individuals he refers to as the ‘‘primitives’’ (1924).

After that, Henslin studied the superstitions of St.Louis taxi drivers who play craps during their work breaks and compared them to Skinner’s pigeon (1967).

I wanted in my thesis to help anthropology to reconstruct lost knowledge regarding gambling and beliefs about magic in capitalist society.

Session 3-3-A: The ‘Circles Concept’ Of Gambling Addiction: An Empowered Framework For Change, Harry B. Mayr

International Conference on Gambling & Risk Taking

The original ‘Circles Concept of (Gambling) Addiction’ was developed by Harry Mayr in 1982, while working as an addictions counsellor in a community-based health centre. It has always been a ‘user friendly’ concept … applicable and understood by people from all cultures, across all ages, and with or without an addiction issue. Years later, people have informed Mr Mayr how they still remember ‘those circles’, and how the concept helped them.

The ‘Circles Concept of (Gambling) Addiction’ is therefore a concept remembered as much for its visual cues as its verbal explanation – and thus applicable across languages, cognitive and …

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.

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 …

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: A Comparative Analysis Of Design And Motivation In Slot Machines And Video Games, Daniel Sahl

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

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).

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 …
