The Interplay Between Families and Schools: Immigrant and Native Differentials in Educational Outcomes

We examine the effects of school context on educational outlooks and outcomes of the children of immigrants, in comparison with natives in Spain, an under-represented case in the international literature and a fast growing immigration destination in Europe. Using two sources of hierarchical data, 2011 Chances Survey and the 2010 Secondary Schooling National Evaluation Survey, which cluster students across schools, we investigate the factors that contribute to the formation of long term educational careers. To start with we analyze performance from both an objective (test scores in mathematics) and subjective perspective (estimation by children and also their parents of whether individual school results will allow them to proceed to tertiary education). Then we turn our attention to the adjusted educational expectations (controlled for prior performance) of children. Our results reveal the different way that school context works for immigrant and native origin children. Our multilevel regression analysis finds significantly worse school results among immigrants (test scores). Although immigrant children themselves understand the constraints that such disadvantage imposes on their future educational careers, immigrant parents seem to hold on to a rather unrealistic position. This parental optimism in turn seems to boost the career expectation of immigrant children independent of school effects. Thus while school context determines the performance of immigrant origin students to a greater extent than those of natives, the opposite is true for expectations. The formation of aspirations is more family-oriented among immigrants, and thus more positive, than among natives

Age of Information in Multicast Networks with Multiple Update Streams

We consider the age of information in a multicast network where there is a single source node that sends time-sensitive updates to $n$ receiver nodes. Each status update is one of two kinds: type I or type II. To study the age of information experienced by the receiver nodes for both types of updates, we consider two cases: update streams are generated by the source node at-will and update streams arrive exogenously to the source node. We show that using an earliest $k_1$ and $k_2$ transmission scheme for type I and type II updates, respectively, the age of information of both update streams at the receiver nodes can be made a constant independent of $n$. In particular, the source node transmits each type I update packet to the earliest $k_1$ and each type II update packet to the earliest $k_2$ of $n$ receiver nodes. We determine the optimum $k_1$ and $k_2$ stopping thresholds for arbitrary shifted exponential link delays to individually and jointly minimize the average age of both update streams and characterize the pareto optimal curve for the two ages

Why Is the Universe of Sets Not a Set?

According to the iterative conception of sets, standardly formalized by ZFC, there is no set of all sets. But why is there no set of all sets? A simple-minded, though unpopular, "minimal" explanation for why there is no set of all sets is that the supposition that there is contradicts some axioms of ZFC. In this paper, I first explain the core complaint against the minimal explanation, and then argue against the two main alternative answers to the guiding question. I conclude the paper by outlining a close alternative to the minimal explanation, the conception-based explanation, that avoids the core complaint against the minimal explanation
