Surveillance of large geotechnical projects requires autonomous collection of data from a wide range of instrument types. An equally large range of data formats are employed by these measurement systems. A data exchange protocol is needed to make field data available for interpretation on a variety of platforms. This paper...
Most studies of crack response have focused on opening and closing of a crack in the plane of the wall in which the crack occurs. Crack movement also occurs perpendicular or normal to the plane of the wall. This paper will examine and compare the in-plane and out-of-plane (normal) response...
Cracking is one of the most common concerns cited by owners of structures adjacent to construction or mining blasting. While a large database of case studies documenting the relative insignificance of ground motion induced by responsible blasting compared to weather effects on cracks in nearby structures has been established, the...
In this essay, key features of Nigerian governance since independence are reviewed. The military had ruled the county for thirteen years and civilian politicians, in two phases, had done so for ten. Military governments involved significant participation by civilians, so there was overlap between these successive systems. Moreover, the military...

They took place in a context of economic decline and policy disarray. However, the opposition still retained an important share of...
This article resumes the exploration of Nigeria’s political economy and the entrenchment of a prebendal mode of attitudes and behaviors. It takes up the shift to a mono-mineral export economy, the socio- economic proclivities of the dominant class, the considerable expansion in the state’s economic role, and the distinct pattern...
The building of the Second Republic required a military government, which had been deeply engaged in shaping the Federation over almost fifteen years, performing as an impartial umpire in the electoral choice of its successors. This complex process is dissected in this article together with an analysis of the relative...

The 1979 elections demonstrated that, however much political party leaders may seek to build a national following, they are “trapped” by ethnic and other sectional...
