Fracturing Opportunity
Fracturing Opportunity demonstrates a simple yet profound idea - that educational opportunity is learned. And if it is learned, then it can be taught and taught more equitably. This book brings sociocultural theories of learning and development to bear on the persistent problems of inequality in college access, and presents an innovative framework for understanding and addressing the historic inequities that plague educational opportunity. Through ethnographic documentation of Mexican migrants' educational experiences, the book moves beyond traditional inquiry on aspiration, academic preparation, and college matriculation to explore the deeper, more fundamental sense-making processes that mediate how students among the most vulnerable cultural communities in the United States engage in college-going. This is an excellent text for educators and researchers interested in equal educational opportunity generally, Mexican migrant and Chicano education in particular, and scholars interested in applied critical sociocultural theory and critical ethnographic methods.
Structural Health Monitoring of Long-Span Suspension Bridges
Long span suspension bridges cost billions. In recent decades, structural health monitoring systems have been developed to measure the loading environment and responses of these bridges in order to assess serviceability and safety while tracking the symptoms of operational incidents and potential damage. This helps ensure the bridge functions properly during a long service life and guards against catastrophic failure under extreme events. Although these systems have achieved some success, this cutting-edge technology involves many complex topics that present challenges to students, researchers, and engineers alike. Systematically introducing the fundamentals and outlining the advanced techno...
The Foundational Handbook on Improvement Research in Education
The Foundational Handbook on Improvement Research in Education is a pathbreaking effort to build a field of research committed to producing the practical knowledge needed to advance educational access, quality, and equity. This is research distinguished by the use of inclusive, iterative approaches to analysis, design, implementation, and evaluation to understand and address educational opportunities, needs, and problems grounded deeply in school and community contexts. Designed for researchers, students, and educators, the handbook elaborates the intellectual foundations, explores the organizational and policy contexts, reviews approaches, and examines methods of improvement research. It features contributions from a plural community of researchers with expertise in the learning sciences, instructional improvement, organizational and policy studies, and research methodologies, many with extensive experience collaborating with teachers, leadership, families, and advocates in local problem solving and design.
Baryonic Dark Matter
The visible universe is a small perturbation on the material universe. Zwicky and Sinclair Smith in the 1930s gave evidence of invisible mass in the Coma and Virgo Clusters of Galaxies. Better optical data has only served to confound their critics and the X-ray data confirms that the gravitational potentials are many times larger than those predicted on the basis of the observed stars. Dynamical analyses of individual galaxies have found that significant extra mass is needed to explain their rotational velocities. On much larger scales, tens of megaparsecs, there is suggestive evidence that there is even more mass per unit luminosity. What is this non-luminous stuff of which the universe is made'? How much of it is there? Need there be only one kind of stuff? There are three basic possi bili ties:- all of it is ordinary (baryonic) matter, all of it is some other kind of (non-baryonic) matter, or some of it is baryonic and some is non-baryonic.

#youthaction
Social media and digital tools permeate the everyday lives of young people. In the early stages of commentary about the impact of the digital age on civic life, debates revolved around whether the Internet enhanced or discouraged civic and political action. Since then we have seen new media move to center stage in politics and activism--from the 2008 US election to the 2011 Arab Spring to the Occupy movement. We have also seen new patterns in how different sub-groups make use of digital media. These developments have pushed people to move beyond questions about whether new media are good or bad for civic life, to ask instead: how, under what conditions, and for whom, do new digital tools bec...
