The actual construction time and cost of construction projects may be affected by the client, project and contractual characteristics and in many cases can be very different from the contract time and cost. In this paper, details of 93 Australian construction projects are used to develop several models for actual construction time and cost prediction. A forward crossvalidation regression analys...

The study suggests that the construction sector plays a leading role in the improvement of socioeconomic conditions and the built environment in every country. The study revealed that the construction sector remains as one of the key sectors in the economy in terms of its share of GDP (i.e. 9.1% for 19932011 period) and the overall industrial output( i.e. 35.9% for 1993-2011 period). Also, the ...

The launching of the JOT provides a welcome opportunity to resume the Eiffel column that ran for many years in JOOP from 1998 (edited first by Rock Howard from whom I took over in 1998). It will run pretty much like its predecessor, with a mix of contributions by guest columnists and by me, and a mix of topics — from language matters to methodological issues of object-oriented software construc...

Sign languages (SL) require a fundamental rethinking of many basic assumptions about human language processing because instead of using linear speech, sign languages coarticulate facial expressions, shoulder and hand movements, eye gaze and usage of a three-dimensional space. SL researchers have therefore advocated SL-specific approaches that do not start from the biases of models that were ori...

Construction Grammar has reached a stage of maturity where many researchers are looking for an explicit formal grounding of their work. Recently, there have been exciting developments to cater for this demand, most notably in Sign-Based Construction Grammar (SBCG) and Fluid Construction Grammar (FCG). Unfortunately, like playing a music instrument, the formalisms used by SBCG and FCG take time ...

Traffic problems are the most prominent urban dilemmas, especially during recent years, since the capacity of old traffic arteries don’t meet the increasing volume of population and vehicles, therefore, adopting some measures in order to enhance the capacity of existing roads has been placed on the agenda of urban managers. Changing the existing intersections to over changes is one of these met...
