Thirty years ago, the Church Committee completed what was and still is the most exhaustive look at any government's secret intelligence agencies. The Committee showed that in times of crisis, even constitutional democracies are likely to violate their laws and forget their values. In this reflection, the Committee's Chief Counsel states that by examining the full record over time, the Committee found that it was insufficient to blame abuses solely on intelligence agencies. Ultimate responsibility was properly fixed with the presidents, attorneys general, and other high executive branch officials. Seven general lessons, including the danger of excess secrecy, are drawn from his experience. These lessons are valuable for the present struggle with terrorism. 相似文献

The economic and social gains from electronic commerce (e-commerce) that promote innovation, industry upgrading and economic growth have been widely discussed. China’s successful experience with e-commerce has had a positive effect in transforming consumer-goods sectors of the economy and motivating economic reform. This article looks at how e-commerce reduces barriers to entry and enables firms to move up the value chain by using the global value chain framework to analyse the impact of e-commerce on the upgrading trajectories and governance structures of China’s apparel industry. For large Chinese brands, e-commerce has enabled end-market diversification. For small- and medium-sized enterprises, e-commerce has facilitated entry with functional upgrading as well as end-market upgrading. In the “two-sided markets” created by platform companies, the “engaged consumers” are the demand side of this market, and “e-commerce focused apparel firms” are the supply side of the new market. Consumers and platforms are more directly involved in value creation within this emerging internet-based structure. 相似文献

Ein Verwalter hat auch im Bereich der ordentlichen Verwaltung generellen Direktiven und individuellen Weisungen der Mehrheit
der Wohnungseigentümer Folge zu leisten, soweit sie nicht offenkundig gesetzwidrig sind. Dies bedeutet aber nicht, dass der
Verwalter den Wünschen eines dominierenden Mehrheitseigentümers in solchen Belangen auch ohne formelle, die Mitwirkungsrechte
aller Miteigentümer wahrende Beschlussfassung quasi vorauseilend gehorchen darf, wenn sie den erkl?rten Interessen der Minderheit
widersprechen. 相似文献

The ability of two mass spectrometric methods, surface-assisted laser desorption/ionization-time of flight-mass spectrometry (SALDI-TOF-MS) and direct analysis in real time (DART-MS), to detect the presence of seven common explosives (six nitro-organic- and one peroxide-type) in spiked latent fingermarks has been examined. It was found that each explosive could be detected with nanogram sensitivity for marks resulting from direct finger contact with a glass probe by DART-MS or onto stainless steel target plates using SALDI-TOF-MS for marks pre-dusted with one type of commercial black magnetic powder. These explosives also could be detected in latent marks lifted from six common surfaces (paper, plastic bag, metal drinks can, wood laminate, adhesive tape and white ceramic tile) whereas no explosive could be detected in equivalent pre-dusted marks on the surface of a commercial lifting tape by the DART-MS method due to high background interference from the tape material. The presence of TNT and Tetryl could be detected in pre-dusted latent fingermarks on a commercial lifting tape for up to 29 days sealed and stored under ambient conditions. 相似文献
