Towards a multi-scale multi-modal model of infrastructure interdependence
No full textThere has in recent years been an increasing focus in both research and policy on considering infrastructure networks as interdependent systems, rather than as separate interconnected entities. This has resulted from a recognition that the functionality of transport, energy, water, waste, and ICT networks is inextricably linked, with their efficiency, effectiveness and resilience dependent on their connectivity to the other systems with which they interact. The importance of such interdependencies has been reflected in policy making, with the recent establishment of a National Infrastructure Commission by the UK government, and in the development of a range of research projects focusing on network interconnections (in other words, on infrastructure nexus thinking). This session will focus on the geographies of interdependency between transport and other infrastructure networks, examining how nexus thinking can 1) enhance existing approaches to dealing with and exploiting infrastructure interdependencies, in order to realise a more efficient, equitable and sustainable use of transport infrastructure and 2) help understand and address the impacts of interdependencies on society
Appropriate Similarity Measures for Author Cocitation Analysis
No full textWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis

Evidence for prion protein expression in enteroglial cells of the myenteric plexus of mouse intestine
No full textTransmissible spongiform encephalopathies (TSEs) are slowly progressive and fatal neurodegenerative diseases affecting man and animals. They are caused by pathological isoforms (PrP(Sc)) of the host-encoded cellular prion protein (PrP(C)). There are two crucial factors for the initiation of infection, namely host cells PrP(C) expression and sufficient sequence homology between the PrP(Sc) to which the animal is exposed and its own PrP(C). In acquired TSEs, the gastrointestinal tract (GIT) is the main prion entry site. Hence, it is of paramount importance to an understanding of the early pathogenesis of prion infections, to characterize the GIT cell types constitutively expressing PrP(C). Twenty-three mice were utilized, including wild-type (WT), Prnp knock-out (KO), and PrP(C)-overexpressing (tga20/tga20) animals, of 20-30 g in weight and of either sex. In all three groups of mice, PrP(C)-immunoreactivity (IR), along with glial fibrillary acidic protein (GFAP)-IR and synaptophysin (Syn)-IR were investigated by means of indirect immunofluorescence in wholemount preparations from several gut regions, from duodenum to rectum. In WT mice, PrP(C)-IR and GFAP-IR co-localization was observed in enteric glial cells (EGCs) from all intestinal segments. PrP(C)-overexpressing mice showed a stronger PrP(C)-IR in EGCs, whereas the same cells exhibited no PrP(C)-IR in Prnp-KO mice. Our findings clearly indicate that EGCs of the mouse intestine constitutively express PrP(C); thus they could be a potential target for infectious prions.Valeria Albanese, Victoria A.
