The economic impact of the Australia–US free trade agreement

The Australia–United States Free Trade Agreement (AUSFTA) came into effect in 2005. It was the second preferential trade agreement that Australia signed, after its agreement with Singapore, and marked a departure from the primacy of Australia's previous trade policy of unilateral and multilateral trade liberalisation toward preferential liberalisation. This paper assesses the economic effects of AUSFTA by applying the Productivity Commission's gravity model of trade from its Bilateral and Regional Trade Agreements review. The evidence reveals AUSFTA resulted in a fall in Australian and US trade with the rest of the world—that the agreement led to trade diversion. Estimates also show that AUSFTA is associated with a reduction in trade between Australia and the United States.     

3D Digital Survey of Iron Tie-Rods in Masonry Buildings: Cross-Sections Analysis and Error Estimation

Ancient iron tie-rods are handcrafted elements with large geometric irregularities, due to production techniques (they are shaped by hammering and linked by hot-forging) and corrosion processes. In common practice, their cross section (that is one of the main parameter to assess their strength) is manually measured on site with a manual caliber. By analyzing a set of detailed three-dimensional (3D) digital surveys of real ancient tie-rods, this study provide an evaluation of the errors made by in-situ manual geometric measurements. In particular, it shows that, in some cases, manual on-site survey is sufficiently reliable and has errors that fall below 10%. Moreover, it shows that when tie-rods have high corrosion levels in hidden zones (typically those close or within the retaining walls) the on-site survey of visible parts only may produce far greater errors that exceed 100%, leading to a strong overestimation of the cross-section of the tie. The ongoing study is a first step toward the definition of correction coefficients to be applied to the on-site manual measurements of ancient tie-rods, with the final aim to improve the reliability of structural analyses.     

Historical Use of Metal Tie-Rods in the Italian Territory: Treatises,Essays, and Manuals through Four Centuries of History

The use of metal tie-rods in buildings is documented and visible in many Italian areas since the 15th century. This article refers to the study of treatises, manuals and essays from the 15th to the early 20th century, mainly in the Italian context with some exceptions of certain foreign texts that, due to their diffusion and importance, have greatly influenced the technical literature on the subject. Technology is an expression of the social, economic, cultural, political and juridical events of a country and, as such, is deeply linked to the times and territories in which it develops. However, it is also closely linked to the laws of nature and to forms of communication, therefore it is useful to compare, underlining the analogies and differences, the knowledge and the ways of the productive and technical process in a long-term analysis.     

Modern roads as UNESCO World Heritage sites: framework and proposals

There has been noticeable development in the protection of linear infrastructure by UNESCO, whether on its cultural, technological or historical merits. However, with the exception of other means of transport incorporated within the field of industrial archaeology or recognised by the CIIC under the category of cultural routes, little or no consideration has been given to roads built from the mid-eighteenth century to the early part of the twentieth century. In view of this situation, this paper has the following aims. Firstly, to define the concept of ‘modern road’ and provide a brief analysis of the historical development and current situation of the same. Secondly, to assess the main contributions made to date regarding the heritage dimension of modern roads. Thirdly, to reconstruct the process of defining linear cultural landscapes, historic transportation corridors, cultural routes and heritage canals, railways and roads, in accordance with the considerations raised by ICOMOS and UNESCO. Finally, to contribute to the debate on the definition, characterisation and assessment of modern roads as world heritage assets, both intrinsically and in relation to established heritage categories.     

Tourism–conservation enterprises as a land-use strategy in Kenya

Since the early 1990s, nature conservation organizations in Eastern and Southern Africa have increasingly attempted to integrate their objectives with those of international development organizations, the land-use objectives of local communities and the commercial objectives of tourism businesses, in order to find new solutions for the protection of nature and wildlife outside state-protected areas. The increased inclusion of the market in conservation initiatives has led to diverse institutional arrangements involving various societal actors, such as private game reserves, conservancies and conservation enterprises. The Koija Starbeds ecolodge in Kenya – a partnership between communities, private investors and a non-governmental organization – serves as a case study for emerging institutional arrangements aimed at enabling value creation for communities from nature conservation. Based on a content analysis of data from individual semi-structured interviews and focus group interviews, as well as a document and literature review, this article reveals a range of benefits for community livelihood and conservation. It also identifies a range of longer term governance challenges, such as the need to address local political struggles, the relations between partners and transparency and accountability in the arrangement.     

Children,social capital and health: increasing the well‐being of young people in rural Wales

This paper explores the usefulness of employing the concept of social capital within a research project investigating the best ways of meeting the health and well‐being needs of young people living in rural Wales. The first part of the paper provides an overview of some of the current research exploring the relationship between social capital, health and young people. The second part provides an overview of findings from an action research project to illustrate how social capital is conceived and applied in this context. It concludes by stating that children and young people do actively generate, draw upon and negotiate their own social capital, and that this is an under‐utilised resource in terms of promoting health and well‐being.
