Re-investigating Dempster's idea on evidence combination.

In this paper, we investigate the problem encountered by Dempster's combination rule in view of Dempster's original combination framework. We first show that the root of Dempster's combination rule (defined and named by Shafer) is Dempster's original idea on evidence combination. We then argue that Dempster's original idea on evidence combination is, in fact, richer than what has been formulated in the rule. We conclude that, by strictly following what Dempster has suggested, there should be no counterintuitive results when combining evidence.

The University Incubator: Insights in the Entrepreneurial Process from a Network Perspective

Research to date has identified incubator units as an effective mechanism for supporting the growth and development of small entrepreneurial firms. Advantages are gained not only from the provision of appropriate facilities and external managerial expertise on site, but also from the opportunity to develop entrepreneurial networks facilitated by the spatial proximity of incubator firms. Therefore, the research question upon which the paper is based investigates the impact of context, in other words the degree to which the networking opportunities provided by the university incubator support the small firm in its pursuit of sustainability and growth

A long-term study (1949-2005) of experimental introductions to an island; freshwater amphipods (Crustacea) in the Isle of Man (British Isles)

Using data from field introduction experiments with Gammarus spp. conducted in the rivers of a small island, commencing in 1949, with resampling in the 60s, 70s, 80s, 90s and finally in 2005, we aimed to examine the long-term interaction of the native freshwater amphipod Gammarus duebeni celticus with the introduced G. pulex. Using physico-chemical data from a 2005 island-wide survey, we also aimed to find what environmental factors could influence the distribution of the two species.
