Dimitrov et al. argue that nonregimes are a worthy object of research attention that can contribute to international regime theory. Case studies, however, are still sparse. In this article, I examine Arctic haze, an issue area where a transnational environmental problem existed but no regime formed. Arctic haze was (re‐)discovered in 1971 but by 2000, the window of opportunity to form a regime had closed. What factors explain why an Arctic haze regime was not formed between 1971 and 2000? I claim science‐based factors play the dominant role. An analytical approach applicable to the science‐policy interface was employed. Using this approach, I conclude that the Arctic haze nonregime is best explained by the absence of scientifically documented and compelling transboundary consequences to ecosystems and humans. This is a product of the unique nature of the Arctic atmosphere.  相似文献

This article seeks to analyze the Foreign Office reaction to the Cicero spy affair. Papers newly released in 2003 and 2005 provide some fascinating insights into leaks that were occurring at the Ankara embassy long before Cicero, how diplomats tried to trap the notorious spy and how the Foreign Office sought to block any outside interference in its investigations, particularly from the Security Service (MI5). The article also sheds light on how the Foreign Office attempted to deal with the fallout when the full scale of the Cicero leak became publicly known. At the time, the Foreign Office investigation into the leak failed to identify Cicero but it did highlight that Sir Hughe Knatchbull-Hugessen, the British Ambassador to Turkey, was culpable in allowing documents in his possession to be photographed. It appeared, however, that Hugessen had got off lightly when he was rewarded with the ambassadorship at Brussels in September 1944. Why had this situation come about? Was the Foreign Office closing its ranks to protect one of its own? And, did this confirm oft-repeated accusations that as an institution, the Foreign Office could not be trusted when it came to security?  相似文献

Sir Ronald H. Campbell was the first British ambassador during the Second World War to manage a key bilateral relationship with a wartime ally. When the Germans invaded France in May 1940, Campbell's Embassy was transformed from a diplomatic reporting post into a frontline base that had to brief London not only on the political situation in France but also on strategic military matters. However, the British ambassador would constantly struggle to register his authority in the overall management of the Franco-British relationship, and more often than not, was bypassed by Whitehall departments, special advisors and senior ministers. Campbell only found himself in a more pivotal role as communications between the British and French Governments disintegrated and the latter moved to Bordeaux. It then fell upon Campbell to make some of the most dramatic decisions in twentieth century Franco-British history.  相似文献

Impurity profiles of methamphetamine tablets seized in Thailand have been investigated. The samples are extracted with small amounts of ethyl acetate under alkaline condition and the extracts are analyzed by capillary gas chromatography. Nine compounds (1,2-dimethyl-3-phenylaziridine, ephedrine, methylephedrine, N-formylmethamphetamine, N-acetylmethamphetamine, N-formylephedrine, N-acetylephedrine, N,O-diacetylephedrie, methamphetamine dimer) are identified as impurities in methamphetamine tablet. Caffeine and ethyl vanillin are also detected as diluents and/or adulterants, and acetylcodeine monoacetylmorphine and diacetylmorphine are contained in many samples. In addition, trans-3,4-dimethyl-5-phenyl-2-oxazolidone is newly found as an impurity. For characterization and comparison of methamphetamine tablet exhibits, intensely and commonly detectable nine peaks are selected as the factor for multivariate analysis. The procedures reported here permit classification of 250 analyzed exhibits into five groups and characterization of classified groups.  相似文献

In this study, a set of key Service Efforts and Accomplishments (SEA) indicators was determined for higher-education external reports. Personal interviews were conducted with presidents and administrators from 28 colleges to determine their preferences for and the usefulness of performance indicators. Participants’ perceptions were analyzed using the analytic hierarchy process. In addition to determining indicators, the study discovered an unexpectedly high correlation between the key indicators selected by private and public institutions.  相似文献
