This paper produces new estimates of the rate of organizational forgetting in the well-known case study of US wartime ship production. Estimates obtained using data constructed from primary sources at the National Archives yield rates of forgetting that are much smaller than previously reported, and may well be zero. The richness of the data make it(More)
In this thesis, we investigate reliable modelling within a stochastic process algebra framework. Primarily, we consider issues of variance in stochastic process algebras as a measure of model reliability. This is in contrast to previous research in the eld which has tended to centre around mean behaviour and steady-state solutions. We present a method of(More)
We investigate the use of 2 tagging technologies: Near Field Communication (NFC) and 2-dimensional barcodes. Our investigation combined a field trial and interview based study with an experimental evaluation. The field trial focused on users' experience of the usability of NFC for a range of trial services, users' perceptions of NFC use in their daily life(More)
While prior research has considered the desirability and implications of employee mobility, less research has considered factors affecting the ease of mobility. This paper explores a legal constraint on mobility —employee noncompete agreements—by exploiting Michigan's apparently-inadvertent 1985 reversal of its enforcement policy as a natural experiment.(More)
Background and Life History The decline of American eel Anguilla rostrata in many parts of its North American range is well documented, especially in the Great Lakes basin (Haro et al. 2000; Cassel-man 2003). We have chosen to end this section with a short summary of the declines and associated causal factors, as some of the complexities associated with the(More)
Recent evidence has shown that entrants into self-employment are disproportionately drawn from the tails of the earnings and ability distributions. This observation is explained by a multi-task model of occupational choice in which frictions in the labor market induces mismatches between firms and workers, and mis-assignment of workers to tasks. The model(More)
We have designed and implemented a system that permits the measurement of network Quality of Service (QoS) parameters. This system allows us to objectively evaluate the requirements of network applications for delivering user acceptable quality. We use FastEthernet taps to monitor full-duplex traffic and programmable network interface cards to extract all(More)
