The rise of virtualisation and cloud computing is one of the most significant features of computing in the last 10 years. However, despite its popularity, there are still a number of technical barriers that prevent it from becoming the truly ubiquitous service it has the potential to be. Central to this are the issues of data security and the lack of trust that users have in relying on cloud services to provide the foundation of their IT infrastructure. This is a highly complex issue, which covers multiple inter-related factors such as platform integrity, robust service guarantees, data and network security, and many others that have yet to be overcome in a meaningful way. This paper presents a concept for an innovative integrated platform to reinforce the integrity and security of cloud services and we apply this in the context of Critical Infrastructures to identify the core requirements, components and features of this infrastructure. 相似文献

The authors report the case of a 25-year-old white woman at 7 months' gestation who died suddenly and unexpectedly at home. Anatomic findings at autopsy included a tongue contusion, glomerulonephritis, changes indicative of systemic hypertension, and trophoblastic microemboli in the lungs. Review of the prenatal care record disclosed 3+ proteinuria 2 days before death. The features of the postmortem examination were consistent with clinically undiagnosed preeclampsia-eclampsia and glomerulonephritis. The authors discuss the rarity of fatal preeclampsia-eclampsia, the contribution of concomitant glomerulonephritis, and the significance of trophoblastic microemboli in the lungs. 相似文献

This paper reports on sexual behavior, knowledge of sexually transmitted diseases (including AIDS) and condoms, and condom use among African-American and white incarcerated adolescents in Seattle, Washington. One hundred nineteen adolescents in a juvenile detention facility completed questionnaires that assessed their lifetime and recent sexual behaviors, an objective test of disease and condom knowledge, attitudes and norms regarding condom use with steady and casual partners, prior condom use, and intentions to use condoms. The results indicate that these adolescents are at high risk by a number of indicators: They have a high average number of partners, have unprotected vaginal and anal sex, and many have sex with known or suspected drug users. Their overall knowledge of condoms and sexual transmitted diseases risks is high, but high knowledge is not correlated with positive attitudes; for one attitude measure, high knowledge is significantly correlated with negative attitudes toward condom use. These findings suggest that programs designed solely to increase knowledge are unlikely to effect behavior change.This research presented in this paper was supported by a research grant from the National Institute of Allergy and Infectious Diseases.Received Ph.D. in social psychology from the University of Washington.
