The costs of playing free games on gambling websites

One of the most common ways to entice gamblers to play online is to make them try out games in ‘demo’, ‘practice’ or ‘free play’ mode. At one level, most would argue that playing for points rather than money is little more than innocuous fun. However, is this really the case? Dr. Mark Griffiths and Abby McCormack, of Nottingham Trent University, and Dr Jonathan Parke, of the University of Salford, examine some of the real costs of playing free online games on gambling websites

Profiting From Purpose: Profiles of Success and Challenge in Eight Social Purpose Businesses

Offers an in-depth analysis of eight community-based human service and youth-serving nonprofit organizations that received assistance from Seedco's Nonprofit Venture Network to develop their capacity to launch social purpose businesses

Electrical characterization Of SiGe thin films

An apparatus for measuring electrical resistivity and Hall coefficient on both thin films and bulk material over a temperature range of 300K to 1300K has been built. A unique alumina fixture, with four molybdenum probes, allows arbitrarily shaped samples, up to 2.5 cm diameter, to be measured using van der Pauw's method. The system is fully automated and is constructed with commercially available components. Measurements of the electrical properties of doped and undoped Si-Ge thin films, grown by liquid phase epitaxy reported here, are to illustrate the capabilities of the apparatus

Image correlation and sampling study

The development of analytical approaches for solving image correlation and image sampling of multispectral data is discussed. Relevant multispectral image statistics which are applicable to image correlation and sampling are identified. The general image statistics include intensity mean, variance, amplitude histogram, power spectral density function, and autocorrelation function. The translation problem associated with digital image registration and the analytical means for comparing commonly used correlation techniques are considered. General expressions for determining the reconstruction error for specific image sampling strategies are developed
