Machine learning can deliver unprecedented performance. Its application domain has expanded into safety-critical cyber-physical systems such as UAVs and self-driver cars. However, the safety assurance of vehicular control has two conditions: 1) an analytical model of system behaviors such as provable stability, and 2) the software safety certification process (e.g., DO 178C) requires that the software be simple enough so that software safety can be validated by a combination of model checking and near exhaustive testing. Although ML software, as is, does not meet these two safety requirements, the real-time physics model supervised ML architecture holds the promise to 1) meet the two safety requirements and 2) enable ML software to safely improve control performance and safely learn from its experience in real-time. This talk will review the structure of the proposed architecture and some methods to embed physics into ML-enabled CPS control.

Before the advent of computers around 1950, optimization centered either on small-dimensional problems solved by looking at zeroes of first derivatives and signs of second derivatives, or on infinite-dimensional problems about curves and surfaces. In both cases, "variations" were employed to understand how a local solution might be characterized. Computers changed the picture by opening the possibility of solving large-scale problems involving inequalities, instead of only equations. Inequalities had to be recognized as important because the decisions to be optimized were constrained by the need to respect many upper or lower bounds on their feasibility. A new kind of mathematical analysis, beyond traditional calculus, had to be developed to address these needs. It built first on appealing to the convexity of sets and functions, but went on to amazingly broad and successful concepts of variational geometry, subgradients, subderivatives, and variational convergence beyond just that. This talk will explain these revolutionary developments and why there were essential.

The notion of expertise is integral to all forms of institutional and professional practice in many domains – in education, healthcare, social welfare, law, journalism, banking, information technology, marketing, translating and interpreting services etc. It is a concept addressed by scholars across many disciplines – cognitive science, sociology, anthropology, psychology, language/communication studies, among others. There are, however, enduring problems of definition, description and measurement of expertise. Some scholars draw attention to the ongoing ‘crisis in expertise’ and others pronounce the ‘death of expertise’ in contemporary society.
More humbly, I begin with a characterisation of professional expertise very broadly to include scientific, experiential, technological, organisational, legal, ethical and communicative knowledge. This then leads me to the notion of ‘distributed expertise’, which extends beyond the individual remit and the conventional lay-expert divide. For instance, in the healthcare domain, a significant development afforded by internet-based technology is the increased level of patients’ e-health literacy and, consequently, democratisation of expertise. This amounts not only to accessing health information digitally, but also the phenomenon of patients ‘doctoring’ themselves in ‘the now of its presence’, i.e., ‘expert patients’ becoming instrumental in self-diagnosis and even self-treatment.
Additionally, ‘distributed expertise’ is also constitutive of ‘expert systems’, e.g., diagnostic and interventionist technologies as well as decision aids mediated by algorithms and templates. This is what I refer to as the technologization of expertise. I suggest that there is overreliance on ‘expert systems’ by both experts and lay persons in everyday decision making. Access to and use of ‘expert systems’ in optimal ways inevitably necessitates a reconfiguration of the very conditions and consequences of professional expertise.

As a recent New York Times editorial proclaimed, "The Global Order Isn't Working. It's Time for Something Different." To teach environmental history and environmental ethics is to reacquaint ourselves with the facts that we need to try to build, while there is still time, a new cooperative order that understands this: simple fact: that other people and other countries are quite literally "the air we breathe." Moreover, all who claim to be ethical persons must take seriously the notion of inter-generational equity and try to act upon it. This notion should, in theory, come more easily to countries whose traditions have built upon classical/ Confucian learning, for those traditions say that the most important marker of human behavior is working toward common ends (qun 群) while "learning what is enough" (zhi zu 知足). Put another way, many resources within the Chinese tradition may strengthen our resolve to act more constructively in less short-sighted ways.

The real-life stroke scenario presented in ANA101x Human Anatomy has invited vigorous discussions on whether fully recovery from a severe stroke is possible and how it could happen. The knowledge of anatomy has arisen a series of queries on body functioning that are commonly implicated in stroke. An extension of human anatomy fundamentals towards functional anatomy has formed the basis of intervention approaches for functional recovery undertaken by different healthcare professionals, which is guiding the ultimate goals of post-stroke rehabilitation program for regaining independence and quality-of-life of the individuals. Therefore, this course is particularly designed to delineate the stroke recovery process and its underlying scientific rationales.
Continuing using the same clinical case of Mr Law, this course walks you through the recovery journey, known as stroke care pathway involving multiple healthcare professionals to compose module ONE. In module TWO, intervention approaches practiced in key healthcare disciplines underpinned by the functional anatomy will be explored. Finally, the course knowledge will be assessed using an experiential approach using a set of mini case studies derived from the mainstream scenario of Mr Law.

Everyone wishes to know the future!
Although we do not have the magic crystal ball to show us the future, we have interviewed more than forty (40+) international industrialists, academics, and business leaders. They are experts in their area and the drivers behind the industry. Our guests will share their views of the future and potential of the fashion industry with you.
During the interviews, we focused on the following questions:
What are the current challenges?
What are the new main directions in the coming five to ten (5 – 10) years?
What kind of new technologies will become popular?
Will there be any new business models (new ways of doing business)?
What role can a government play?
Will there be any ideology that may bring a big impact?
We fully understand that learners may face the obstacle of terminology and background. We will introduce the background of the fashion supply chain first. Then, we take the learners to attend the interviews week by week, sector by sector. Most importantly, the course content is bilingual in Chinese and English. Learners will enjoy our learning supports.
Suitable for students, consumers, anyone who is interested or working in the fashion business.

In this CIHK webinar, we will discuss the material conditions of and historical background to the use of Classical Chinese or Literary Sinitic in writing-mediated brush conversation between literati of Sinitic engaged in cross-border communication within Sinographic East Asia or the Sinographic cosmopolis, which corresponds with today’s China, North Korea, South Korea, Japan (including Okinawa, formerly the Ryukyu Kingdom) and Vietnam. Compared with speech as a modality of communication, real-time writing-mediated interaction between talking humans, synchronously face-to-face, seems uncommon. In any society, speaking is premised on one condition: the interlocutors must have at least one shared spoken language at their disposal, but even then, there are circumstances under which speaking is either physically not feasible or socially inappropriate. Could writing function as an alternative modality of communication when speaking is not an option due to the absence of a shared spoken language, as in cross-border communication settings? Whereas real-time writing-mediated face-to-face interaction is rare where a regional lingua franca was known to exist (e.g., Latin and Arabic), there is ample historical evidence of literati of Classical Chinese or Literary Sinitic from different parts of Sinographic East Asia conducting ‘silent conversation’, synchronously and interactively in writing mode using brush, ink, and paper. Such a pattern of writing-assisted interaction is still practiced and observable in pen-assisted conversation – pen-talk – between Chinese and Japanese speakers today, thanks to the pragma-linguistic affordance of morphographic, non-phonographic sinograms (i.e., Chinese characters and Japanese kanji). We will outline the historical spread of Classical Chinese or Sinitic texts from the ‘center’ to the ‘peripheries’, and the historical background to the acquisition of literacy in Sinitic by the people there. Their shared knowledge of Sinitic helps explain why, for well over a thousand years until the 1900s, literati from these places were able to speak their mind by engaging in ‘Sinitic brush-talk’ 漢文筆談 in cross-border communication.

Focusing on tensions and links between national formation and international outlooks, this talk shows how classical world visions persist as China’s modernizers and revolutionaries adopted and revised the Western nation-state and cosmopolitanism. The concepts of tianxia (all under heaven) and datong (great harmony) have been updated into outlooks of global harmony that value unity, equality, and reciprocity as strategies of overcoming interstate conflict, national divides, and social fragmentation. The talk will delve into two debates: the embrace of the West vs. aspirations for a common world, and the difference between liberal cosmopolitanism and socialist internationalism.

During the sixteenth and early seventeenth centuries, the relaxation of the Ming sea ban, along with the arrival of the Europeans, generated a multipolar environment in East Asia. It revolved around the intra-Asian exchange centered upon Chinese silk and Japanese silver, and a nascent global flow of New World bullion to China and spices for Western Europe. The situation changed during the mid-seventeenth century amid mounting restrictions on overseas contacts from the Tokugawa shogunate of Japan and the consolidation and militarization of Chinese merchants under the Zheng family. By 1683, when the Qing forced the Zheng to surrender and occupied their bastion of Taiwan, China had achieved naval preeminence in the East Asian sea lanes. Other than a few outposts, the Europeans had largely withdrawn from the area north of island Southeast Asia, which remained under the hegemony of the Dutch East India Company. In 1684, the Qing court legalized private trade and travel abroad, prompting another wave of overseas migration. Authorities in China and across eastern maritime Asia enacted policies that kept the Qing merchants and immigrants separate from the earlier Ming loyalists. Additionally, both groups of Chinese were accorded significant political, economic, and legal privileges. This infrastructure, backed by Qing naval power, paved the way for the “Chinese century” in maritime Asia.
