Environmental fluid mechanics (EFM) is the scientific study of transport, dispersion and transformation processes in natural fluid flows on our planet Earth, from the microscale to the planetary scale. This book brings together scientists and engineers working in research institutions, universities and academia, who engage in the study of theoretical, modeling, measuring and software aspects in environmental fluid mechanics. It provides a forum for the participants, and exchanges new ideas and expertise through the presentations of up-to-date and recent overall achievements in this field.

Some reports estimate that nearly 50% of teachers entering the profession leave within the first five years (Alliance for Excellent Education 2004; Ingersoll, 2003; Quality Counts 2000). One explanation of why teachers leave the profession so early in their career might be related to the emotional nature of the teaching profession. For example, teaching is an occupation that involves considerable emotional labor. Emotional labor involves the effort, planning, and control teachers need to express organizationally desired emotions during interpersonal transactions.
