Process and IT (Editorial)

Purpose – This paper’s aim is to provide a fresh perspective on how to address process improvement and information technology (IT) in an integrated fashion in order to improve the efficiency of the construction process. Design/methodology/approach –This paper looks at the problems associated with the “conventional” way of addressing IT within construction, and suggests improvements based on integrating three core organisational resources: people, process and technology. Findings – The existing view that IT on its own brings organisational benefits leads to only marginal improvements in organisational efficiency if not resulting in negative impact. However, by correctly integrating people, process and IT initiatives, significant benefits can be achieved. Originality/value – This paper provides value by providing a conceptualisation for addressing people, process and technology within the construction sector

Stratifying modular representations of finite groups

We classify localising subcategories of the stable module category of a finite group that are closed under tensor product with simple (or, equivalently all) modules. One application is a proof of the telescope conjecture in this context. Others include new proofs of the tensor product theorem and of the classification of thick subcategories of the finitely generated modules which avoid the use of cyclic shifted subgroups. Along the way we establish similar classifications for differential graded modules over graded polynomial rings, and over graded exterior algebras.Comment: 37 pages; minor changes from the first version.

Localising subcategories for cochains on the classifying space of a finite group

The localising subcategories of the derived category of the cochains on the classifying space of a finite group are classified. They are in one to one correspondence with the subsets of the set of homogeneous prime ideals of the cohomology ring $H^*(G,k)$.Comment: 5 pages, minor changes, accepted for publication in C. R.
