E-mail in government: Not post-bureaucratic but late-bureaucratic organizations

Empirical research provides evidence that electronic communication does not change government agencies into post-bureaucratic organizations. Structuration Theory is used to explore the interaction between e-mail use, communication patterns of civil servants, and two bureaucratic characteristics: formalization and hierarchy. Previous research suggested that the use of e-mail leads to less formalization and less hierarchy, but empirical research in three bureaucratic organizations in the Netherlands leads to different conclusions. First, the use of e-mail leads to informal formalization: the style of communication is more informal but the content focuses less on personal issues and emphasizes efficient recordings of agreements. Second, the use of e-mail leads to hierarchical horizontalization: horizontal contacts take a more central position in bureaucratic organizations but these horizontal contacts are tightly linked to vertical structures. The result of the interaction between e-mail and government bureaucracy is horizontal communication directly linked to vertical structures. Electronic communication turns government agencies into late-bureaucratic organizations.     

Environmentally-induced stone decay: the cumulative effects of crystallization–hydration cycles on a Lincolnshire oopelsparite limestone

An investigation has been undertaken at St Andrew’s church, Walpole St Andrew, Norfolk, to establish the underlying causes of the observed stone decay to the upper parts of the six stone piers. The stone decay was first recorded in the early 1930s. The salt-contaminated masonry within the church has been shown to undergo severe salt decay during the summer, with little damage occurring over the winter months. The south aisle piers have been shown to decay 2.5 times faster than the north aisle piers. Although crystallization–hydration cycles have been identified, the rate of decay is at its greatest when the cycling is relatively infrequent. This was not the expected trend. Furthermore, it has been shown that during extended periods where the ambient relative humidity is less than 75%, the rate of decay reaches a maximum. It is the length of this ‘drying’ period that apparently has the greatest influence on the rate of decay and could explain the significant difference in the rate of decay between the south and north aisle piers. The results have serious implications for passive conservation, where it is often recommended to lower the ambient relative humidity to well below the equilibrium relative humidity of the salt contaminant, to avoid crystallization–hydration cycles. Since, at the time of building, the church was situated on the coast, it is possible that the sodium chloride contamination occurred during the building process (1440–1520), particularly since the area was prone to sea-flooding at this time. Alternatively, the salt could have been applied as a treatment during the general restoration of 1897. Whatever the source of the salt, it seems likely that the ambient environment was changed by the insertion of a sealed floor in 1897, which could account for the onset of the salt decay.     

Educational and Employment Testing: Changing Concepts in Measurement and Policy

How will the expansion of the concept of construct validity affect validation practice in employment testing? How does the need for consequential validity differ in educational and employment testing? How do the research bases differ for performance assessment in these settings? Are there parallel trends in policies for test use in education and industry?
