Sommario/riassunto |
|
This book follows an example-driven, simplified, and practical approach to using OpenCL for general purpose GPU programming.If you are a beginner in parallel programming and would like to quickly accelerate your algorithms using OpenCL, this book is perfect for you! You will find the diverse topics and case studies in this book interesting and informative. You will only require a good knowledge of C programming for this book, and an understanding of parallel implementations will be useful, but not necessary. |

Sommario/riassunto |
|
Consumers trust is a key factor in dealing with rising concerns about food safety and food quality, but only few studies have dealt with consumer attitudes and none of them has tried to model the process of consumer response. This book reports the main findings of an european project aimed at analysing trust along the food chain and its relationship with food risk communication. The papers collected investigate the mechanisms that determine the social diffusion of trust, examining the interplay of the psychological, sociological and economic factors; and analyze the impact of the food risk communication policies on consumers and producers and on the society as a whole. |
