近年来,19世纪的口号"大角逐"在国际能源领域再次抬头。但是,西方学者往往选择少数案例来证明油价上升的主要原因是中国与印度的竞争,以及油田的买卖。本文通过对中印竞争、合作与独立购买案例的实证调研,认为双方的竞争与合作案例的数量不仅少,而且两类交易的数量相当,相比之下,平行独立的中印能源外交案例最多。中印两国能源公司都基本遵照市场规律与游戏规则,而且多数能源行动并不属于过时的份额油"大角逐"。 相似文献

Suicides or suicide attempts with power saws (band, circular or chain saws) are rather rare events and only a few case reports exist in the forensic literature. The use of a band saw, in particular, has been extremely rare in cases of suicide.We report two cases of suicide that occurred in the same suburban area, three years apart. In each case, the victim was a carpenter and had a history of psychiatric disorder and/or of prior suicide attempts.We summarize the findings of the death scene investigations, the pertinent autopsy findings, and also summarize the world literature pertaining to suicide committed with power saws. 相似文献

In the face of an unprecedented surge in United Nations (UN) peacekeeping activity over the past three years—with now almost 100,000 military, police and civilian personnel deployed on four continents in 18 operations—there is a need for the UN to develop a comprehensive doctrine that better defines what modern UN peacekeeping has become and that covers the full range of civilian peacebuilding activities that are now a standard feature of Security Council mandates. This paper serves as a primer and proposes an agenda for debate on such a doctrine. It summarises evolutions in thinking and practice over the past 15 years. It also highlights key conceptual challenges and political fault lines to be reconciled in order for a new comprehensive doctrine to enjoy broad support of the UN's 192 Member States, while still providing relevant guidance to thousands of personnel on the front-lines of the effort to help rebuild war-torn states. 相似文献

Only limited data exist concerning the utility of complementary specimens in heroin-related deaths. As such, this report employed a validated LC-MS-MS method to quantify 6-monoacetylmorphine (6-MAM), 6-acetylcodeine (6-AC), and their metabolites morphine and codeine in blood with (BN) and without preservative (B) and the additional unpreserved specimens of vitreous humor, urine, stomach contents, and bile from 20 postmortem cases in which heroin was the primary cause of death. The median concentration of 6-MAM in BN was 0.011 mg/L, B was 0.008 mg/L, urine was 0.186 mg/L, vitreous humor was 0.022 mg/L, stomach contents was 0.147 mg/L, and bile was 0.012 mg/L. Only one case was found to be positive for 6-AC in B (case 6, 0.002 mg/L), and the median concentration of 6-AC was 0.002 mg/L in BN, 0.012 mg/L in urine, 0.003 mg/L in vitreous humor, 0.057 mg/L in stomach contents, and 0.004 mg/L in bile. These findings present new information on the distribution of these analytes in complementary matrices and support their inclusion for accurately determining the role of heroin in opioid-related deaths. 相似文献
