Time Series Tests of Income Convergence with Two Structural Breaks: An Update and Extension

This paper uses newly available long-span data on real per capita incomes from 1900-2001 to test for stochastic convergence in a diverse group of 29 countries. To perform our tests, we utilize the two-break LM unit root test of Lee and Strazicich (2003) and endogenously determine two distinct structural breaks in level and trend for each country. Despite including both OECD and non-OECD countries, we find significant evidence that incomes are stochastically converging. World War II is the most often identified time period of breaks. The results represent slightly more evidence in favor of convergence than reported in the study by Dawson and Sen (forthcoming) using the same sample of countries.

Exploring heritage through time and space : Supporting community reflection on the highland clearances

On the two hundredth anniversary of the Kildonan clearances, when people were forcibly removed from their homes, the Timespan Heritage centre has created a program of community centred work aimed at challenging pre conceptions and encouraging reflection on this important historical process. This paper explores the innovative ways in which virtual world technology has facilitated community engagement, enhanced visualisation and encouraged reflection as part of this program. An installation where users navigate through a reconstruction of pre clearance Caen township is controlled through natural gestures and presented on a 300 inch six megapixel screen. This environment allows users to experience the past in new ways. The platform has value as an effective way for an educator, artist or hobbyist to create large scale virtual environments using off the shelf hardware and open source software. The result is an exhibit that also serves as a platform for experimentation into innovative ways of community co-creation and co-curation.Postprin

Coupling of Energy Into PCB Traces in a Reverberant Environment: Absorption Cross-section and Probability of Susceptibility

Predicting the risk of susceptibility to electromagnetic interference for a system would be of significant interest to the EMC community. In this paper, we consider the coupling of electromagnetic energy into Printed Circuit Board (PCB) traces and how it relates to the power balance model of shielding effectiveness. We show results of some measurements of the absorption cross-section of a load on a PCB trace and compare them with previously published results

Tank tests to determine the effect on planing-tail hulls of varying length, width, and plan-form taper of afterbody

Tests were conducted in Langley Tank no. 2 on models of an unconventional flying-boat hull called a planing-tail hull to determine the effects on resistance of varying a number of afterbody parameters. The effects of varying length, width, and plan-form taper of the afterbody are presented. Tests were made with afterbodies of two widths, two lengths, and two tapers. In the tests the depth of step and the angle of afterbody keel were held constant.(author

The Attorney-Client Privilege

History suggests that the attorney-client privilege is the oldest of the evidentiary privileges. It probably arose at common law during the 1500\u27s, concurrent with the right to trial by jury. Judges initially viewed the privilege as a vindication of the oath and the honor of the attorney. However, during the late 1700\u27s, courts began to assert that the privilege\u27s purpose was to encourage clients to make full disclosure to their counsel, by providing subjectively for the client\u27s freedom of apprehension. In 1871, the Virginia Supreme Court5 stated that [i]f the privilege did not exist at all, every one would be thrown upon his own legal resources; deprived of all professional assistance, a man would not venture to consult any skillful person, or would only dare to tell his counsel half his case. Today, courts continue to state that the benefits of full disclosure justify the privilege, and frequently assert that without such full disclosure an attorney may not be able to adequately advise his client

Allopurinol and Nitric Oxide Activity in the Cerebral Circulation of Those With Diabetes: A randomized trial

OBJECTIVE—Type 2 diabetes increases risk of stroke, perhaps because of impaired cerebrovascular basal nitric oxide (NO) activity. We investigated whether this activity is improved by a 2-week course of the xanthine oxidase inhibitor allopurinol
