The British decision to withdraw from the Palestine mandate in 1947–1948 may at first glance appear contradictory to British strategic interests. The Middle East and Palestine were vital to Britain's Cold War strategy, and its government repeatedly stated the need for a continued British presence in the region to prevent Soviet expansion. Why then withdraw from Palestine just as the Cold War started? The traditional explanation is that Britain withdrew because of economic exhaustion and its inability to remain a great power. But this article shows that economic and strategic considerations both contributed to the decision to withdraw. Britain's involvement in Palestine threatened to undermine its relations with the independent Arab states, and the decision to withdraw from Palestine was therefore taken in the hope that this would secure Britain's position in the rest of the Middle East.  相似文献

Measuring support for democracy in societies where democratic institutions do not exist or do not function well is a challenge faced by many researchers around the world. In societies moving either toward or away from democracy, the very meaning of ‘democracy’ is often in question and institutions and practices that go by the label of ‘democratic’ may vary widely from accepted norms. As a result, respondents are likely to interpret survey questions on democratic concepts in unpredictable ways. This article examines some of the ways respondents in non-democratic or imperfectly democratic countries may misinterpret the meaning of survey questions and consequently how their answers may mislead researchers. Previous research has focused on problems with abstract concepts like ‘democracy’. Evidence presented here – from interviews with Russians – shows that the problem is broader and covers more kinds of questions than previously thought. A strong potential for miscommunication also exists with more concrete questions about institutions and values, forced choices that encourage respondents to change the meaning of questions, and questions about trust in institutions.  相似文献

In Carney v Newton [2006] TASSC 4 the Tasmanian Supreme Court heard a claim that the defendant breached his duty of care by failing to properly diagnose and treat a node positive carcinoma in the plaintiff's breast tissue. At trial, argument turned on the actual dialogue that took place during the initial consultation, with significant reliance on the clinical notes of the defendant. The court gave considerable weight to "expert" witnesses in ascertaining the acceptability of the defendant's conduct concerning the maintenance and interpretation of his clinical notes. This raises important questions in relation to proof of quality of medical records as part of the current professional standard of care, as modified by recent legislation in most jurisdictions.  相似文献

In this study we reviewed the post-mortem cases in the years 1999-2004 that were presented at the Netherlands Forensic Institute. The concentrations of amphetamine-based drugs in femoral blood from cases of suspected unnatural death were compared with concentrations in whole blood from non-fatal cases of driving under the influence (DUI cases) and with literature. Furthermore, the combinations with other drugs and/or alcohol were investigated. Amphetamine-based drugs were present in 70 post-mortem cases and 467 DUI cases. The most detected amphetamine-based drug was MDMA, followed by amphetamine. The presence of MDA could usually be explained by metabolism of MDMA. Methamphetamine and MDEA were rarely present. Frequently, the amphetamine-based drugs were taken in combination with alcohol and/or other non-amphetamine-based drugs such as cocaine or cannabinoids. The 70 post-mortem cases were divided into 38 amphetamine-based drug caused (i.e. the amphetamine-based drug directly caused or contributed to the death) and 32 amphetamine-based drug related deaths (i.e. death was not directly caused by the amphetamine-based drug). In the latter category, other (poly)drug intoxications and death by violence or drowning were the most frequent causes of death. In 30 cases, MDMA caused death directly. The range in blood concentrations of MDMA in these cases was substantial, i.e. 0.41-84 mg/L with a median concentration of 3.7 mg/L (n=30). MDMA blood concentrations in the MDMA related deaths (n=20) and in the DUI cases (n=360) varied up to 3.7 and 4.0 mg/L, respectively. Seven victims died from the direct effects of amphetamine; the blood concentration of amphetamine ranged from 0.24 to 11.3 mg/L, with a median concentration of 1.7 mg/L (n=7). The median concentrations of amphetamine in the amphetamine related deaths (n=13) and the DUI cases (n=208) were much lower, i.e. 0.28 and 0.22 mg/L, respectively. Amphetamine blood concentrations up to 6.0 and 2.3 mg/L were seen in the drug related deaths and DUI cases, respectively. The most frequently encountered amphetamine-based drugs in the investigated deaths were MDMA and amphetamine. The majority of MDMA- and amphetamine-caused deaths, i.e. 90% of these deaths, occurred with blood concentrations above 1.5 and 0.80 mg/L, respectively. MDMA and amphetamine blood concentrations in drug related deaths and DUI cases, however, overlap the range of fatal concentrations. Therefore, MDMA or amphetamine concentrations should never be used alone to establish the cause of death.  相似文献

Bejaht man die Beendigung der überlassung der Dienstwohnung auch für den Fall der Beendigung des Arbeitsverh?ltnisses durch den Arbeitgeber, dann hat dies auch für den übergang des Arbeitsverh?ltnisses auf einen neuen Arbeitgeber infolge Betriebsübergangs zu gelten. Der neue Arbeitgeber tritt anstelle des alten Arbeitgebers in das Arbeitsverh?ltnis ein. Im Verh?ltnis zwischen Arbeitnehmer und altem Arbeitgeber kommt es – wie bei der Kündigung oder Entlassung des Arbeitnehmers durch den Arbeitgeber – zu einer Beendigung der bisherigen Beziehung. Wird das Arbeitsverh?ltnis beendet, entf?llt mangels abweichender Vereinbarung auch das Benutzungsrecht an der Dienstwohnung. Eine Aufkündigung nach der ZPO hat nicht zu erfolgen, vielmehr ist sogleich eine R?umungsklage zul?ssig.  相似文献
