Improved space-time forecasting of next day ozone concentrations in the eastern U.S.
No full textThere is an urgent need to provide accurate air quality information and forecasts to the general public and environmental health decision-makers. This paper develops a hierarchical space–time model for daily 8-h maximum ozone concentration (O3) data covering much of the eastern United States. The model combines observed data and forecast output from a computer simulation model known as the Eta Community Multi-scale Air Quality (CMAQ) forecast model in a very flexible, yet computationally fast way, so that the next day forecasts can be computed in real-time operational mode. The model adjusts for spatio-temporal biases in the Eta CMAQ forecasts and avoids a change of support problem often encountered in data fusion settings where real data have been observed at point level monitoring sites, but the forecasts from the computer model are provided at grid cell levels. The model is validated with a large amount of set-aside data and is shown to provide much improved forecasts of daily O3 concentrations in the eastern United State
Tooth erosion : prevention and treatment
No full text"Erosion frequently coexists to varying extents with other tooth wear processes, such as abrasion and attrition, but erosion is often not recognized as being present or is confused withother wear mechanisms." "The aim of this book is to inform ... of the causes and treatment of tooth surface loss from erosion. Chapters are presented as a series of extensively-referenced articles, which include information on the importance of the oral environment and lifestyle behaviors in influencing tooth erosion, and practial information on the preventionof tooth erosion and the restoration of lost tooth substance." --pref.Kevin HK Yip, Roger J Smales, John A Kaidoni
An investigation into Chinese cybercrime and the underground economy in comparison with the West
No full textWith 420 million Internet users, China has become the world’s largest Internet population. Yet, the Internet penetration rate in China is only 31.6%, which means that the Chinese Internet population has the potential to triple in size in the foreseeable future. With cybercrimes transcending national boundaries, the security of the Internet in China is becoming increasingly significant to the global Internet. As in the West, organised cybercrimes are flourishing in China. With a rapidly expanding Internet population, China is fast becoming a giant hub of cybercrime activities. Therefore, it is in the interest of Western cyber-security experts to increase their attention to China’s cyber-security

The rise of Chinese cyber warriors: towards a theoretical model of online hacktivism
No full textChina is frequently reported as the source of many transnational cyber-attacks. Yet, there have been very few studies on the people behind such attacks. In this paper, we have studied some of the reasons behind the rise of a specific form of hacking: hacktivism emanating from China. Using various criminological theories, as well as political and sociological approaches, a novel theoretical framework behind Chinese hacktivism is proposed in this paper. This is supported by an empirical analysis that was carried out on the membership growth patterns of online Chinese hacktivist forums and the observed patterns are used to support the proposed framework.</p
Implications of oral biofilms in medically at risk persons
No full textThere is the need to understand the composition of oral biofilms so that appropriate preventive and treatment regimens, including using appropriate antimicrobials, can be developed further. Additionally, when the systemic effects from specific microorganisms in oral biofilms are better understood, more targeted preventive treatment options may be recommended for persons at high risk for potential systemic diseases such as cardiovascular disease, and for aspiration pneumonia. Hence, the possible association between periodontopathic microorganisms, and also between cariogenic microorganisms in high caries risk persons, and systemic diseases requires further research involving metagenomic and large well-designed clinical studies. Effective preventive oral care is important for reducing potential systemic diseases. © 2012 The Editorial Board of Journal of Biomedical Research.Kevin H.-K. Yip, Roger J. Smale
University of California Press eScholarship editions in process
No full textIn this collection of passionately argued essays, the internationally acclaimed poet and critic Wai-lim Yip calls Western scholarship to account for its treacherous representation of non-Western literature. Yip moves from Plato to Hans-Georg Gadamer, from Chuang-tzu to Mao Tse-tung, from John Donne to Robert Creeley, as he attempts to create a double consciousness that includes the state of mind of the original author and the expressive potentials of the target language. He aims, first, to expose the types of distortions that have occurred in the process of translation from one language to another and, second, to propose guidelines that will prevent this kind of linguistic violence in the future
Chi-Square and F Approximations of Hetelling's Generalized T0^2
No full textTitle: Chi-Square and F Approximations of Hetelling's Generalized T0^2, Author: Davin Y.N. Yip. Location: ThodeChi-square approximation of Retelling's generalized T0^2 have
been investigated by Professor Tiku. In this project, further results
on the approximation are presented and examined. Also, an F approximation
for the distribution of Retelling's generalized T0^2 is proposed. The
results are compared with other approximations and discussed.ThesisMaster of Science (MSc
