Multitemporal analysis for preservation of obsidian sources from Melka Kunture (Ethiopia): integration of fieldwork activities,digital aerial photogrammetry and multispectral stereo-IKONOS II analysis

An integrated analysis of recent satellite imageries and dated aerial photos demonstrated to be a good investigation tool (Gallo et al., 2009) for the identification of new sites and for the assessment of landscape changes of wide archaeological areas in Ethiopia.     

A Presumed Hydraulic Apparatus for the Transport of Live Fish,Found on the Roman Wreck at Grado,Italy

The Roman wreck found off Grado, not far from the city of Aquileia in the north Adriatic Sea, was recovered in 1999. The ship carried various kinds of amphoras with processed fish. A lead pipe, inserted in the hull near the keel, is curious evidence which the authors try to explain. The pipe could be connected to a piston‐pump to suck water. A theoretical reconstruction demonstrates how this apparatus could work and that it could be used to feed a tank to allow trading in live fish over a long distance. © 2011 The Authors     

Optical spectroscopy as a rapid and low-cost tool for the first-line analysis of glass artefacts: a step-by-step plan for Roman green glass

Archaeometric research on glass artefacts is continuously evolving and is converging towards a multidisciplinary research domain where different types of techniques are applied depending on the questions asked and the circumstances involved. The technique described in this work is optical spectroscopy. The benefit of this technique being the possibility of building up a knowledge database for a large amount of material in a relatively short period of time and with a relatively limited budget. This is of particular interest for the investigation of extensive and/or unexplored glass collections where a first-line analysis of artefacts could facilitate the selection of material needing further and more detailed examination.     

Difference

Speaking in particular of Oceanic societies, my intention is to reverse the gestalt of Le totemisme aujourd'hui to foreground the role of difference as a fundamental condition of the possibility of society – difference between as well as within societies. I take the point that difference is not just an historical circumstance but that it is indeed a positive value. Accordingly, differentiation is not so much a natural process as it is a cultural intention.     

The Pendulum of Congressional Power: Agenda Change,Partisanship and the Demise of the Post-World War II Foreign Policy Consensus

Many scholars contend that Congress rarely matters in the realm of foreign policy. The source of this collective impotence is often explained by the weaknesses in congressional institutions vis-a-vis the president, as well as a general inability to respond effectively to a dynamic international political environment. We contend that the debate over congressional activism has not adequately addressed the role of agenda change. We analyze all roll call votes in the House of Representatives relating to the international affairs agenda between 1953 and 1998. We find that presidents have become significantly more likely to stake out positions on economic and trade issues as compared to other international issues. We also observe that presidential positions in the realm of foreign policy are increasingly characterized by interparty and interinstitutional conflict. While this increased conflict has dramatically decreased the president's ability to successfully pass executive priorities in foreign affairs more generally, presidential success on economic and trade issues has witnessed a significantly greater decline. We infer from these results that changes to the foreign policy issue agenda represent one important factor that has affected not only the incentives for political parties to participate actively, but also the willingness of Congress to challenge the president in the foreign policy debate.Asked one day whether it was true that the navy yard in his district was too small to accommodate the latest battleships. Henry Stimson (chair of the House Naval Affairs Committee early in the century) replied, 'That is true, and that is the reason I have always been in favor of small ships.'1Carriers have been, are and will be for the foreseeable future an absolutely essential part of our deterrence force…2John Warner, senator from Virginia, home state of Newport News Shipbuilding     

Milestones and Stumbling Blocks,Continued

This commentary is based on a banquet address I presented at the 1989 Pioneer America Society conference. It looks back over the 15 years since hearing an address by Fred Kniffen at the 1974 Pioneer America Society conference, which was published as "Milestones and Stumbling Blocks." Kniffen's work in folk architecture and the work of his friend, Henry Glassie, have greatly influenced my own work in vernacular architecture and material culture. I offer an opinion on our progress in answering Kniffen's call for new efforts to comprehend daily life and the American landscape–our "search for landmarks"–contemplate new trends. My remarks are based on the study of local architecture in Missouri. While I hope for increased activity in field recording of cultural heritage, I wish to emphasize the rather new arena of cultural conservation as we aspire to apply our knowledge in the documentation and encouragement of traditional cultural expression in our nation.     

Vattel's law of nations and just war theory

It has often been said that Vattel's treatise on the law of nations breaks with the tradition of modern natural law and just war theory. Based on a closer examination of Vattel's justification of preventive war and of his assessment of the balance of power in Europe, the paper argues that this criticism is greatly exaggerated, if not entirely misleading.     

Design thinking for city dashboard development: Recommendations from a study of smart asset management in Sydney,Australia

The city dashboard has become an integral component of smart city asset management systems. It leverages data collected from multiple sources to monitor performance and enable evidence-based decision making. This article investigates the use of a design thinking framework to develop a functional and easy to understand city dashboard. The Smart Social Spaces project is used as a case study to illustrate how design thinking can be employed to develop an asset management dashboard, enabling efficient management of public space and infrastructure. The article profiles the unique collaboration between a local government, a multi-disciplinary team of university academics, and a street furniture designer and manufacturer, all located in Sydney, Australia. We unpack some of the design practice nuances that led this project to receive national awards and international recognition, and most importantly, created a user-friendly system to track and maintain public micro assets. We conclude with lessons learnt and recommendations for dashboard development through a design thinking process.
