متن کاملClass Size and Class Heterogeneity
Class Size and Class Heterogeneity We study how class size and composition affect the academic and labor market performances of college students, two crucial policy questions given the secular increase in college enrollment. We rely on the random assignment of students to teaching classes. Our results suggest that a one standard deviation increase in the class-size would result in a 0.1 standar...
متن کاملComplex Algebraic Surfaces Class 11
Last time, we began analyzing geometrically ruled surfaces by studying projectivizations of rank 2 locally free sheaves. We proved: Proposition. Every geometrically ruled surface over C is C-isomorphic to PC(E) for some rank 2 locally free sheaf (vector bundle) over C. The bundles PC(E) and PC(E ′) are isomorphic (over C) iff there is an invertible sheaf (line bundle) L on C such that E ′ ∼= E ...
