Nuclear charge-exchange excitations in localized covariant density functional theory

The recent progress in the studies of nuclear charge-exchange excitations with localized covariant density functional theory is briefly presented, by taking the fine structure of spin-dipole excitations in 16O as an example. It is shown that the constraints introduced by the Fock terms of the relativistic Hartree-Fock scheme into the particle-hole residual interactions are straightforward and robust.Comment: 4 pages, 1 figure, Proceedings of INPC2013, Florence, Italy, 2-7 June 201

Longquan celadon: a quantified archaeological analysis of a pan-Indian Ocean industry of the 12th to 15th centuries

This paper examines the Longquan celadon industry, located in Zhejiang province in China, which flourished mainly between the Southern Song and early Ming dynasties (12th to 15th century). The products of this industry are found on archaeological sites from across China and the Indian Ocean. This paper attempts a quantified analysis of the development of the industry based on archaeological data, focussing on four aspects: production, domestic consumption, overseas consumption and, to a lesser degree, workshop organisation. Although much of the data is still, in many ways, problematic, and many of the conclusions drawn are necessarily tentative, it is possible to demonstrate the value and timeliness of the approach by charting the overall development of this industry and by arguing that the close integration of the four aspects examined indicates that the Longquan celadon industry was an industry of considerable economic significance across much of the Indian Ocean

A Proposed Approach To Comparing the BIM Maturity of Countries

BIM concepts and tools have now proliferated across the construction industry. This is evidenced by the comparative results of BIM adoption rates reported through a number of industry surveys. However these surveys typically cover a small number of industry stakeholders; are intended to establish adoption rates by organizations rather than markets; and are unsupported by theoretical frameworks to guide data collection and analysis. Based on a published theoretical framework, this paper proposes three metrics to augment survey data and help establish the overall BIM maturity of countries. These metrics apply to noteworthy BIM publications (NBP)s and assess their BIM knowledge content (BKC). NBPs are publically-available industry documents intended to facilitate BIM adoption; while BKCs are specialized labels (e.g. report, manual, and contract) used to describe NBP contents. The three metrics - NBP availability, NBP content distribution, and NBP relevance - are applied in assessing the knowledge deliverables of three countries - United States, United Kingdom and Australia - chosen for their similar construction culture and active BIM scene. The paper then discusses how these complementary metrics can inform policy development and identify market-wide knowledge gaps
