The jump-yip display, vigilance, and foraging behaviour of the black-tailed prairie dog (Cynomys ludovicianus)
No full textThe contagious nature of the black-tailed prairie dog (Cynomys ludovicianus) jump-yip display may provide information to signalers and receivers regarding the vigilance of neighbours. Videotaping jump-yip bouts and the behaviour of both bout initiators and respondents within those bouts provided evidence that: 1) individuals became vigilant immediately following jump-yip production, but exhibited minimal changes in their immediate post-jump-yip behaviour with changes in the characteristics of the preceding bout, 2) bout initiators spent more time actively foraging and exhibited vigilance behaviours less frequently with greater levels of response in the preceding jump-yip bout, 3) respondents spent more time actively foraging and less time vigilant following bouts with greater response. These results suggest that black-tailed prairie dogs base behavioural decisions at least in part on the characteristics of their jump-yip bouts and thus the jump yip display may provide information about the vigilance of group members.October 200
Fascial Spaces and Communicating Apertures Found in the Neck. A Visual Learning Module of The Retropharyngeal Space
No full text2023The complex existence of fascial spaces in the head and neck remain vague and difficult to visualize for prospective students. This may be due to historical disagreement on the nomenclature and having only cross-sectional images, which prove inefficient in illustrating every aspect of a fascial space. This raises concern for fundamental knowledge on anatomical relationships found in the head and neck. The objective of this study is to design a learning module that demonstrates the three-dimensional retropharyngeal space (RPS). This study uses a series of research articles and academic textbooks to restate current descriptions of fascia and fascial spaces. In addition, a fresh frozen cadaver was utilized to develop the learning module. We collected a series of cone-beam computed tomography (CBCT) images following injection of radiopaque materials into the RPS. This will lay the foundation of this learning module for the RPS. With appropriate data, a more detailed perspective of fascial spaces could be developed, which could a useful for future health and medical professionals to diagnose and treat the pathway of RPS abscess and infection
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

Structural analysis of online criminal social networks
No full textOver the last decade, a sophisticated underground economy has emerged over the Internet in which cybercriminals collaborate and trade different goods and services. This study takes a unique approach towards understanding the functioning of the underground economy by focusing on the social dynamics between the cybercriminals. Using anonymized private messaging records from four underground forums formerly operating as online black markets, this study aims to examine the structural properties of the networks of personal interactions between the cybercriminals and to turn the findings into actionable intelligence for tackling the problem of profit-driven cybercrime
Lexicon Optimization in Languages without Alternations
No full textLanguages 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.
