The moving force to integrate BIM (building information modeling) tools may come from owners demanding a BIM deliverable to approve the work on these projects. Ifa contractor can produce this deliverable, then obtaining the project could be done in a more convincing way. Contractors are confronted with problems in selecting proper construction methods and applying their knowledge about specific and well-defined technologies to a project. Their decision-making process and better project outcomes can be improved through a database-oriented library of construction methods and therefore, a consistent methodology to classify construction methods is needed. This goal can be achieved by introducing rigorous construction method descriptors. The technology solution and the trending need of owners to pay software companies to develop software that really works for them and contractors are empirically proved in this paper through a technology ontology and BIM-enabled estimating procedure. An exploratory case study is presented. This way, owners can efficiently demand deliverables that can be utilized by them downstream, allowing contractors and subcontracting trades to work efficiently and to assure the daily flow of operations.展开更多

The method is contained in the conceptual framework. The article provides the constitutional legal landscape--or the overarching laws of the land--and the co-regulatory framework within which journalists work. There are four research explications: the Protection of State Information Bill (dubbed the Secrecy Bill), a painting of the president and Freedom of Expression, an arson attack on a community radio station and finally, the death of a photojournalist at the hands of police. The argument here is that the death, the arson attack, the Secrecy Bill, and the shut-down of dissent during the exhibition of the painting of the president all undermine democracy and signify significant closures for the media in the now 20-year-old post-apartheid South Africa. The analysis and reflections will be framed within theories of radical democracy, which argue for more fights and contestations and more voices from the margins in order to deepen democracy, rather than rational consensus which closes the spaces for greater plurality.展开更多
Recent eruption of Unzen Volcano in 1991-1995 caught attention of scientists all over the world because of disastrous character of previous one in 1792.

Intrusion of andesitic magma to the chamber with rhyolitic magma is proposed to be a trigger for these eruptions. T-P-X parameters of two end-member magmas have been estimated several times, but usually estimations are based on phenocrysts assemblages. New results of this research are based on mafic enclaves and groundmass. These results are significant for magma mixing and mingling theory.展开更多
