An investigation into Chinese cybercrime and the underground economy in comparison with the West
With 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
An investigation into Chinese cybercrime and the underground economy in comparison with the West
With 420 million Internet users, China has become the world’s largest Internet population and the Chinese cyber-security has become globally significant. In this investigation, cybercrimes in China were studied from both sociological and technical perspectives using an array of methods including literature review, passive monitoring of online forums and interest groups as well as establishing direct contact with the Chinese cybercriminals. Hacking was found to be immensely popular in China with a population of 3.6 million registered users spanning across just 19 online hacker forums. Financial and political factors were found to be the main motivations for Chinese cybercriminals. Observations from the Chinese hacktivist forums during recent Chinese cyber-attacks against Japan has brought to light some valuable insights into the true state of hacktivism in China and the level of tolerance from the Chinese government towards such actions. Furthermore, it was found that not only do organised cybercrimes exist in China but also an underground economy as sophisticated as that in the West is flourishing at a rapid pace. Estimates from Chinese security experts suggest that the size of the Chinese underground economy may be much larger than that observed in the West. With the support of the Serious Organised Crime Agency (SOCA), the frameworks of organised cybercrime as observed in the West were compared with those observed in China. Significant similarities and differences were found including differences in the tools of trade used and some of the pricing of goods and services advertised in the underground economy. A generic mapping of the underground economy was deduced from the comparison of frameworks

Lexicon Optimization in Languages without Alternations
Languages with few or no alternations have never fitted smoothly into rule-based theories with a commitment to lexical economy. To derive rich surface inventories from more parsimonious underlying inventories, it was necessary to postulate abstract underlying forms even for morphemes which only ever surfaced with one particular allophone. Even if lexical economy was demoted as a paramount consideration, the occurrence of alternations in one small corner of the grammar, such as in loanwords, still forced the linguist back to the abstract and rule-based analysis. This was so because the alternative, a set of phonotactic statements about the surface distribution of allophones, could not alone produce alternations: only rules could do that, and once the grammar included rules, they could be made use of for other purposes, including the non-alternating forms. Output-based theories are tailor-made for language of this type. Surface-true generalizations can be trivially dealt with. When alternations are encountered, they can be understood as the direct result of the pressure to observe these surface constraints, and no special rules are needed.
Using data from vowel systems in several Chinese dialects, Mandarin palatal consonants, and Chaoyang nasalization, it is argued that abstract underlying representations and rules that produce surface forms are highly inefficient for non-alternating systems, in that they frequently require both rules that derive A from B, and rules that derive B from A, in the same contexts. It is proposed that language is learnt on the basis of core data, and that non-core data - language games, poetry, speech errors, onomatopoeia, loanwords - can be used as a probe to investigate the nature of the underlying representations. This paper finds inconclusive evidence for abstract underlying representations, and concludes that the balance of the evidence suggests that learners acquire something rather close to what they hear, unless information from alternations or paradigms forces them to do otherwise. These findings provide support for Lexicon Optimization (Prince and Smolensky 1993).The definitive version of this paper was published in Current Trends in Phonology: Models and Methods (1996)Yip, M.

The digital underground economy: a social network approach to understanding cybercrime
Emphasized in both the National Security Strategy [11] and the Cyber Security Strategy [3], cybercrime is now a Tier-One national threat to the United Kingdom, a threat which must be addressed as our lives become ever more embedded in the digital economy. Recent cybercrime statistics [14, 24] indicate that with hundreds of millions worth of damage, cybercrime remains one of the primary threats facing nations, corporations and ordinary people. The intriguing question then is how has cybercrime managed to evolve into such a persistent problem despite almost a decade of extensive research into cybersecurity

Italy
My contribution in this volume deals with the Court system in Italy and the existing special courts for company and IT disputes and explores the possibility of introducing in our country a Commercial Court dealing with cross-border disputes in line with similar foreign experience
Yucatan Initiative Project: Transforming Yucatan & Texas Through Research, Teaching & Service
The Yucatan Initiative Project (YIP) was established to foster international collaborations of faculty and students between Texas A&M University (TAMU) and member institutions of the Yucatan Research Consortium (SIIDETEY) in the state of Yucatan, Mexico. The YIP was developed to identify knowledge gaps, set research challenges, organize submission of proposals and securing seed funding aimed at producing economic development in both states in the U.S. and Mexico respectively. The Yucatan Initiative Project, now in its 7th consecutive year, has shown to be a successful model for international collaboration to address regional problems and increase exposure for student's global competencies
Crystalline Motion of Interfaces Between Patterns
We consider the dynamical problem of an antiferromagnetic spin system on a two-dimensional square lattice with nearest-neighbour and next-to-nearest neighbour interactions. The key features of the model include the interaction between spatial scale and time scale , and the incorporation of interfacial boundaries separating regions with microstructures. By employing a discrete-time variational scheme, a limit continuous-time evolution is obtained for a crystal in which evolves according to some motion by crystalline curvatures. In the case of anti-phase boundaries between striped patterns, a striking phenomenon is the appearance of some "non-local" curvature dependence velocity law reflecting the creation of some defect structure on the interface at the discrete level
