GDP growth project

Study examines the economic structure and dynamics of the East Midlands and Yorkshire and Humber regions of the UK, using the logic of firm and labour agglomerations and their contribution to GDP as the basis for the analysis

Hacking Digital Video Recorders: Potential Copyright Liability for DVR Hackers and Service Providers

To what extent does Sony\u27s time-shifting fair use argument extend to recent innovations that make it easier for hackers use DVR technology to generate copies of protected material? The author assesses the potential liability of DVR manufacturers against the backdrop of traditional fair use doctrines

Land Application of Domestic Sludge in Cold Climates

Aerobically digested sludge from the Fairbanks sewage treatment plant was worked into the soil on several plots at the University of Alaska in the summer of 1978. Some of the sludge had been air dried for up to six months prior to application while some was taken directly from the thickener. Applications varied from 12 to 100 tons of solids/acre. For sludge applied in July and August, the fecal coliform count decayed by several orders of magnitude by the middle of September.. There was no significant movement of fecal coliform bacteria either vertically or laterally. Lime was used to raise the pH of one plot to 12, completely killing the fecal coliform bacteria within several days. The nutrient distribution demonstrated the potential for enriching soils by sludge addition. The main purpose of the study was to investigate the feasibility of this concept for remote military sites. Air drying followed by land application may represent a viable means of sludge disposal.This study was performed for the U.S. Army Cold Regions Research and Engineering Laboratory (USA CRREL) and was funded under DA Project 4A762720A896, Environmental Quality for Construction and Operation of Military Facilities, Task 02, Pollution Abatement Systems

Factors related to the rejection and/or abandonment of AAC devices

More than 3.5 million Americans have such significant communication disability that they cannot rely on their natural speech to meet their communication needs. As a result, these individuals are severely restricted in their participation in all aspects of life, including their education, employment, family, and community. Augmentative and alternative communication strategies offer great potential to enhance the communication of individuals with complex communication needs, and therefore improve their quality of life. Fifty-two ISAAC members that responded to the online survey utilized a 5 point Likert-type scale (strongly agree to strongly disagree) to rate the importance of factors as they relate to the rejection and/or abandonment. The mean values of ratings were calculated to determine which factors were cited as relevant in predicting AAC device rejection and abandonment. Additionally, an independent T-test was utilized to determine if the factors cited varied depending on the role of the person completing the survey. The results of this investigation indicate that it is imperative to consider a complex interaction of factors pertaining to the individuals who use AAC, their conversational partners, settings in which interactions occur, and devices used to interact, when designing an AAC intervention. The statistical analysis revealed no significance difference in how the respondents rated the factors based on their occupation. Based on the results of the study, a checklist of factors that an AAC practitioner might consider addressing in order to foster acceptance of AAC systems initially and later on was constructed

Laser velocimeter measurements of high-speed compressible flows

Laser velocimeter results were compared and found to be consistent with those obtained with conventional measurement techniques and existing compressible boundary layer theory. Turbulence information at supersonic speed has been successfully obtained in compressible boundary layer with laser system
