This meta-analysis examines the effects of sorting secondary students into different tracks (“between-school” tracking) or classrooms (“within-school” on efficiency and inequality levels an educational system. Efficiency is related to overall learning achievement students, whereas can refer “inequality achievement” (i.e., dispersion outcomes) opportunity” strength influence family background st...

Twofish is a 128-bit block cipher submitted as a candidate for the Advanced Encryption Standard (AES). It has a structure related to the Feistel structure and runs in 16 rounds. In this paper we consider mainly differentials of Twofish and show that there are differentials for Twofish for up to 16 rounds, predicting at least 32 bits of nontrivial information in every round. In addition, it hold...

Introduction Familial Mediterranean fever (FMF) is an autosomal recessive disease associated with a number of mutations of the MEFV gene. To date 246 variants responsible for the disease were identified, one such a variant is E148Q in exon 2. The role of E148Q variant in the development of FMF remains inconclusive. Some authors believe it causes the disease, whereas others favor the concept of ...

In this paper, we consider the collaborative data publishingproblem for anonymizing horizontally partitioned data atmultiple data providers. We consider a new type of “in-sider attack” by colluding data providers who may use theirown data records (a subset of the overall data) in addition tothe external background knowledge to infer the data recordscontributed by other d...

We investigate a mixed economy of an individual rational expert and several naı̈ve near-sightedagents in the context of security decision making. Agents select between three canonical security ac-tions to navigate the complex security risks of weakest-link, best shot and total effort interdependencies.We further study the impact of two information conditions on agents’ choices. W...

That is the way Miriam Butt begins her book. Apparently, she felt that the quote fits her introduction to case theory within grammatical traditions (Latin grammar is one) and their relationship to various notions of case within modern theoretical linguistics. In her introduction to the book, Butt states “...several issues must be dealt with. One is the issue of what “case” really means and what...
