Construction industry involves the highest risk of occupational accidents and bodily injuries, which range from mild to very severe. The aim of this cross-sectional study was to identify the factors associated with accident severity rate (ASR) in the largest Iranian construction companies based on data about 500 occupational accidents recorded from 2009 to 2013. We also gathered data on safety ...

Outline 1. Introduction to relation algebras. Representations. Atom structures. Examples. 2. Using games to build representations. Axiomatising the finite representable relation algebras. 3. 'Rainbow' construction (Hirsch). Monk's theorem that the representable relation algebras are not finitely axiomatisable. 4. Relativised representations. Weakly associative algebras (WA, Maddux). Finite base...

Research in automatic genre classification has been producing increasingly small performance gains in recent years, with the result that some have suggested that such research should be abandoned in favor of more general similarity research. It has been further argued that genre classification is of limited utility as a goal in itself because of the ambiguities and subjectivity inherent to genr...

One of the reforms proposed for Ontario’s broader public sector by the Drummond Report is the establishment of centralized bargaining structures. As Chaykowski and Hickey have argued, such a reform “must consider whether, how, and in what context, alternative bargaining structures and enhanced coordination could yield outcomes which promote efficiencies and improve value.” In this regard, the t...

Besides all the attention given to lattice constructions, it is common to find some very interesting nonlattice constellations, as Construction C, for example, which also has relevant applications in communication problems (multi-level coding, multi-stage decoding, good quantization efficieny). In this work we present a constellation which is a subset of Construction C, based on inter-level cod...

This paper describes our contribution to the SemEval-2015 task 17 on “Taxonomy Extraction Evaluation”. We propose a hypernym detection system combining three modules: a lexico-syntactic pattern matcher, a morphosyntactic analyzer and a module retrieving hypernym relations from structured lexical resources. Our system ranked first in the competition when considering the gold standard and manual ...
