Book Description
K3 surfaces are central objects in modern algebraic geometry. This book examines this important class of Calabi–Yau manifolds from various perspectives in eighteen self-contained chapters. It starts with the basics and guides the reader to recent breakthroughs, such as the proof of the Tate conjecture for K3 surfaces and structural results on Chow groups. Powerful general techniques are introduced to study the many facets of K3 surfaces, including arithmetic, homological, and differential geometric aspects. In this context, the book covers Hodge structures, moduli spaces, periods, derived categories, birational techniques, Chow rings, and deformation theory. Famous open conjectures, for example the conjectures of Calabi, Weil, and Artin–Tate, are discussed in general and for K3 surfaces in particular, and each chapter ends with questions and open problems. Based on lectures at the advanced graduate level, this book is suitable for courses and as a reference for researchers.

Book Description
Christian Ragacs develops contributions to the theory of minimum wages, while taking rationing and spill-over effects on markets other than the labour market into account. Following an introduction into the theory of minimum wages and a discussion of methodological problems, four new theoretical models are developed; two of them comparative static in nature and two models of endogenous growth. The results are contradictory - partly supporting the 'textbook' theory and partly yielding unorthodox results, such as no change in the steady state rates of growth and employment.

Book Description
No issue in American higher education is more contentious than that of race-based affirmative action. In light of the ongoing debate around the topic and recent Supreme Court rulings, affirmative action policy may be facing further changes. As an alternative to race-based affirmative action, some analysts suggest affirmative action policies based on class. In Race, Class, and Affirmative Action, sociologist Sigal Alon studies the race-based affirmative action policies in the United States. and the class-based affirmative action policies in Israel. Alon evaluates how these different policies foster campus diversity and socioeconomic mobility by comparing the Israeli policy with a simulated model of race-based affirmative action and the U.S. policy with a simulated model of class-based affirmative action. Alon finds that affirmative action at elite institutions in both countries is a key vehicle of mobility for disenfranchised students, whether they are racial and ethnic minorities or socioeconomically disadvantaged. Affirmative action improves their academic success and graduation rates and leads to better labor market outcomes. The beneficiaries of affirmative action in both countries thrive at elite colleges and in selective fields of study. As Alon demonstrates, they would not be better off attending less selective colleges instead. Alon finds that Israel’s class-based affirmative action programs have provided much-needed entry slots at the elite universities to students from the geographic periphery, from high-poverty high schools, and from poor families. However, this approach has not generated as much ethnic diversity as a race-based policy would. By contrast, affirmative action policies in the United States have fostered racial and ethnic diversity at a level that cannot be matched with class-based policies. Yet, class-based policies would do a better job at boosting the socioeconomic diversity at these bastions of privilege. The findings from both countries suggest that neither race-based nor class-based models by themselves can generate broad diversity. According to Alon, the best route for promoting both racial and socioeconomic diversity is to embed the consideration of race within class-based affirmative action. Such a hybrid model would maximize the mobility benefits for both socioeconomically disadvantaged and minority students. Race, Class, and Affirmative Action moves past political talking points to offer an innovative, evidence-based perspective on the merits and feasibility of different designs of affirmative action.

Book Description
The study of the symmetric groups forms one of the basic building blocks of modern group theory. This book presents information currently known on the projective representations of the symmetric and alternating groups. Special emphasis is placed on the theory of Q-functions and skew Q-functions.

Book Description
"TRB's National Cooperative Highway Research Program (NCHRP) Report 555: Test Methods for Characterizing Aggregate Shape, Texture, and Angularity examines a methodology for classifying aggregates based on the distribution of shape, texture, and angularity characteristics. The report also explores a test method that it is appropriate for use in central and field laboratories, which measures shape, texture, and angularity characteristics of aggregates used in hot-mix asphalt, hydraulic cement concrete, and unbound base and subbase layers of pavements. Appendixes for the report were published as NCHRP Web-Only Document 80"--Publisher's description.
