Settlement Site

Summary The excavations revealed a stone house and showed that it was oval, 13 m × 10 m, with an interior about 7 m in diameter. In the first occupation phase the entrance was on the SE side. During the second phase this entrance was replaced with one to the NE and the interior was partitioned. The roof was supported on wooden posts. After the building was abandoned it was covered with peat-ash which was subsequently ploughed. There were numerous finds of steatite-tempered pottery and stone implements, which dated the site to late Bronze/early Iron Age. The second settlement, Site B, lay by the shore of the voe and consisted of two possible stone-built houses and a field system. Two trenches were dug across the structures and the results are reported in Appendix I. Although damaged in recent years it was in no further danger.

78 Fordham Law Review 2799 (2010)The Internet is a semicommons. Private property in servers and network links coexists with a shared communications platform. This distinctive combination both explains the Internet's enormous success and illustrates some of its recurring problems.Building on Henry Smith's theory of the semicommons in the medieval open-field system, this essay explains how the dynamic interplay between private and common uses on the Internet enables it to facilitate worldwide sharing and collaboration without collapsing under the strain of misuse. It shows that key technical features of the Internet, such as its layering of protocols and the Web's division into distinct "sites," respond to the characteristic threats of strategic behavior in a semicommons. An extended case study of the Usenet distributed messaging system shows that not all semicommons on the Internet succeed; the continued success of the Internet depends on our ability to create strong online communities that can manage and defend the infrastructure on which they rely. Private and common both have essential roles to play in that task, a lesson recognized in David Post's and Jonathan Zittrain's recent books on the Internet.

The Magnetic Field

AbstractThis paper discusses problems which have as their uniting theme the need to understand the coupling between a stellar convection zone and a magnetically dominated corona above it. Interest is concentrated on how the convection drives the atmosphere above, loading it with the currents that give rise to flares and other forms of coronal activity. The role of boundary conditions appears to be crucial, suggesting that a global understanding of the magnetic field system is necessary to explain what is observed in the corona. Calculations are presented which suggest that currents flowing up a flux rope return not in the immediate vicinity of the rope but rather in an alternative flux concentration located some distance away.

Electrical Substation

The evaluation of a small cairnfield was carried out at Elvanfoot, South Lanarkshire, in advance of the construction of an electrical substation. A pit located beneath one of the cairns contained sherds of Beaker pottery, but there were no artefacts recovered from the remaining cairns. It is thought that the cairnfield may have been field clearance associated with the North Shortcleugh (also known as Harryburn Brae) platform settlements and field system.
