Findings related to language learning that are of interest to researchers The topic of audiovisual speech perception is addressed in Audiovisual Language Learning: How to Crack the Speech Code by Ear and by Eye. The publication presents nine contributions on the perceptual system's reliance on visual speech to process and learn language.

The word agile has moved far beyond its original meaning in helping to transform large organizations. We now know that agile is used as the tool to accelerate an organization's ability to adapt and thrive in a world of accelerating change. This book provides the missing link of how to shift mindsets on how to work effectively. This shift requires an investigation of how we can move organizations in the way they think about work-especially work that does not easily conform to the traditional plan-driven approach. The author takes the reader on a journey to be able to think in an A.G.I.L.E way. The approach taken is reflective and allows time for the insight to understand how to think differently about teams, work, and even organizations. It is said that all organizations are technology organizations, if that is true it brings risks and opportunities that many organizations have not seen before. The framework of the book will help grow a new way of thinking and is anchored in: Adaptability; Growth; Improvement; Leadership; Experience. In order to make the full transition to thinking in an A.G.I.L.E way you will need to challenge everything you think you know about leading and working in large organizations.
