Earth has two types of crust: oceanic crust is relatively young, dense, and made at mid-oceanic spreading centers, whereas continental crust is buoyant, old, and believed to be created in magmatic arcs. However, making continental crust in arcs is problematic because arc magmas are basaltic with 48-50 percent silica, yet continental crust has approximately 60 percent silica and less magnesium than arc basalts. Paradoxically, how scientists think crust is created doesn't match the composition of the continental crust.
Women had a significant impact on the formation of early Christian communities, but (they) have been largely ignored in the history books. Kaisa-Maria Pihlava's new book brings forgotten female leaders to the forefront.
'Cancer Evolution', from CSHLPress, examines cancer progression as an evolutionary process and explores how this way of looking at cancer may lead to more effective strategies for managing and treating it. The contributors review efforts to characterize the subclonal architecture and dynamics of tumors, understand the roles of chromosomal instability, driver mutations, and mutation order, and determine how cancer cells respond to selective pressures imposed by anticancer agents, immune cells, and other components of the tumor microenvironment.
What is the value of learning in out-of-school settings such as science centers, local businesses, and libraries? How are avatars, massive open online courses, and other new technologies shaping online and distance learning? These questions and more are explored in The SAGE Encyclopedia of Out-of-School Learning.
The Arctic is often in the headlines: starving polar bears on melting ice, the reckless hunt for raw materials, an increase in shipping, and the dispute over seal hunting. How should protecting the fragile ecosystem and the indigenous peoples who live there also be achieved? Kristina Schönfeldt from the University of Bonn has now edited a book that offers a systematic insight into the legal issues in this seemingly remote corner of the earth.
The Arab Spring brought down dictators, but true revolution never came or has been thwarted since. University of Illinois Middle East expert Asef Bayat, in a new book, says true revolution was actually never thought out or planned for - at least not the 20th-century kind. "Revolution without Revolutionaries: Making Sense of the Arab Spring" focuses not only on the events of 2011 and after, but also on the nature of revolution itself.
In his new book, dream expert G. William Domhoff presents an integrated neurocognitive theory of dreams that is grounded in the similarities between dreaming and drifting waking thought.
A Henry Ford Hospital physician whose near-death patient experience inspired an organizational campaign to help health professionals communicate more effectively with patients has chronicled her story in a captivating memoir.
Providing students, scholars, and practitioners an introduction to the full scope of the field, SAGE Publishing announces the publication of The SAGE Encyclopedia of Abnormal and Clinical Psychology. The new 7-volume resource contains more than 1,400 signed articles that discuss essential approaches and theories, numerous mental health disorders, assessment tools and psychotherapeutic interventions, and the social, legal, and cultural foundations that have caused controversy in abnormal and clinical psychology.
Plates collide and mountain ranges form, and the why and how are key to understanding orogenic processes. This volume explores linkages between tectonic processes through a series of field, numerical modeling, and laboratory studies, concentrating on feedback mechanisms within orogens by which tectonic processes may influence or predetermine the operation of other processes in space and time.
