Enter the dragon: China's courtship of Hong Kong, 1982–1999

From 1982, when the Chinese government first signalled its intention to take back Hong Kong, to the actual transfer of sovereignty in 1997, the PRC engaged in a long-term campaign to “win friends and influence people” in the British colony. Hoping to prevent a large-scale flight of capital and manpower, and wishing to cultivate a core group of sympathetic local notables as future political leaders, Beijing issued frequent pledges of non-interference in Hong Kong's affairs and adopted classic “united front” tactics — flattering, cajoling, and otherwise wooing potential supporters while snubbing (and sometimes smearing) outspoken critics. Despite intensely negative local reaction to the 1989 “Tiananmen Massacre”, over the long haul Beijing largely succeeded in disarming public fears of a heavyhanded Chinese takeover. Consequently, the handover itself was an extremely calm, tranquil affair. And in the first 2 years of Hong Kong's new status as a “Special Administrative Region” of China, the PRC earned generally high marks for honoring its pledge to uphold the principle of “one country, two systems”.

Influencing Negotiation Willingness in the Middle East: The Potential Contributions of Private Actors

Numerous efforts to solve the Israeli–Palestinian conflict through diplomacy have taken place over the last four decades. To shed light on this dilemma in this article, the role that private actors and nongovernmental organizations (NGOs) can play to enhance the negotiation willingness of nonstate armed groups was examined. It was argued that the NGOs in particular could play key roles in promoting the negotiation willingness of nonstate actors and also in influencing their internal dynamics and increasing their cohesion. Specifically, we examine two pairs of efforts to resolve the conflict in Israel and Palestine: the “Road Map” and the track two Geneva Initiative of 2003, and the Olmert Peace Plan and Jimmy Carter's visit to the Middle East in 2008. In the first pair, NGO efforts yielded unexpected results. The Palestinians were ready to compromise even though the deal offered by the Israelis did not seem very generous. In the second pair, the reaction of the Palestinians to Israeli Prime Minister Ehud Olmert's generous peace offer seemed especially puzzling, illustrating, the internal dynamics between the Palestinian factions. Negotiation willingness was closely related to cohesion, and that cohesion plays an important role in conflict negotiations. President Jimmy Carter's efforts in 2008 to enhance cohesion among the Palestinians illustrated the potential that NGOs have to complement official negotiations.     

Investigating Residential History Using Stable Hydrogen and Oxygen Isotopes of Human Hair and Drinking Water

The relationship between isotopic signals in human hair and geographic region has potential forensic applications for identifying unknown individuals' place of recent residence. This study analyzes δ²H and δ¹⁸O isotopes in residential tap water and bulk hair samples from 17 volunteers representing 12 locations in Ontario, Canada. There is a strong correlation (R² = 0.9) between δ²H and δ¹⁸O values of the water samples. In contrast, the δ²H and δ¹⁸O values of the hair samples are weakly correlated (R² = 0.3), and the greater variability in the data is linked to dietary factors. This study demonstrates that the δ²H and δ¹⁸O values of hair and drinking water can be used to help identify potential place of residence in forensic cases, particularly in relation to proximity to large bodies of water such as the Great Lakes, but interpretations are complicated by the contribution of both water and diet to δ²H and δ¹⁸O values in hair.     

Calcium and Phosphorus Detection Using Benchtop Versus Handheld X‐ray Fluorescence Spectrometers

Elemental analysis of calcium (Ca) and phosphorus (P) has been shown to be useful in differentiating skeletal and nonskeletal material. X‐ray fluorescence spectrometry (XRF) is an attractive, nondestructive technique for forensic anthropologists, and the development of portable XRF instrumentation is promising for field applications. This study examines the performance of handheld XRF instrumentation operated in air compared to a traditional benchtop XRF device that has the ability to control the analysis atmosphere. Both instruments can be used to effectively distinguish skeletal from nonskeletal remains. However, as the measurement atmosphere affects detection levels for calcium and phosphorus, Ca/P ratios obtained from the instruments and analysis conditions were found to differ significantly, with analyses conducted in air showing significantly lower phosphorus detection. Consequently, comparison of Ca/P ratios to conclude skeletal versus nonskeletal origin must be based on data collected under similar analysis conditions.

Detection and Classification of Ignitable Liquid Residues Using a Fluorescence‐Based Vapor‐Sensitive Microsphere Array*

Abstract: This paper describes the application of microsphere vapor sensing arrays to the detection of ignitable liquid (IL) vapors as both pure vapors and as residues (ILRs) on simulated fire debris samples. The temporal fluorescence response profile of the microsphere array generated a reproducible pattern unique to each analyte that could be used to classify subsequent sensor responses. This system, together with a support vector machine pattern recognition algorithm, was used to address several different IL and ILR classification scenarios. High classification accuracy (98%) was maintained over more than 200 vapor responses and the array was able to identify ILs when presented to the pattern classification algorithm within a dataset containing 11 other volatile compounds. Both burned and unburned IL treated samples were classified correctly greater than 97% of the time. These results indicate that microsphere vapor sensing arrays may be useful for the rapid identification of ILs and ILRs.
