These notes are meant as complements to the paper [5] which served as backbone for most of the material covered in my lectures delivered at the Oregon Programming Languages Summer School 2011 “Types, Semantics and Verification” (videos should be soon available at http://www.cs.uoregon.edu/Activities/ summerschool/summer11/). In particular, we give a brief account of Munch-Maccagnoni’s polarised...

These lectures will be about the approximability of constraint satisfaction problems (CSPs). Definition 1.1. Let D be a domain of cardinality q. We usually write D = {0,1,2, . . . , q − 1} and often call the elements of D labels. Let Γ be a nonempty finite set of nontrivial relations (predicates) over D, with each R ∈ Γ having arity ar(R) ≤ k. We usually write an r-ary relation as R : Dr → {0,1...

Despite decades of policy intervention to increase college entry among low-income students, substantial inequalities in college going by family income remain. Policy makers have largely overlooked the summer after high school as an important time period in students' transition to college. During the post-high school summer, however, students must complete a range of financial and informational ...

Richmond came to the Clinic near the end of the Summer School. Because he had failed his work in a regular seventh grade the previous year he was a pupil in the Demonstration Class, conducted by the University of Pennsylvania during the summer session. In the Demonstration School his work was no better than it had been during the regular school term. It was, therefore, considered advisable to h...

OBJECTIVE To assess the effects of winter/summer school breaks on occurrences of influenza-like illness (ILI). METHODS We jointly analysed ILI surveillance data with the timing of school breaks in a temperate district in Beijing, China from 2008 to 2015. ILI incidence rate ratios (IRRs) of schoolchildren (5-14 and 15-24 years of age) to adults (25-59 and >60 years of age) were used to measure...
