[牙牙學語] 普遍來說，幼童6個月時，就會開始有牙牙學語的聲音，到了一歲，就會開始說有意思的單字或詞語。有家長會問：「如果我孩子到了一歲只會發出『咿咿呀呀』的聲音，甚至於還沒開口發聲，到底是什麼問題呢？是否代表他們完全還沒發展語言？其他幼童說的單字又是什麼呢？」我聽一聽言語治療臨床導師，楊浩怡姑娘的解說。

Have you ever come across times when you get particularly nervous, say during a presentation, you find it extra hard to speak smoothly? Most of us may stop at times when we talk, so how do we differentiate between Normal Dysfluency and Stuttering? Are kids struggling with words due to language ability or are they stuttering? Will they naturally outgrow stuttering? How do speech therapists help adults and children who stutter?
大家有否試過在某些時間特別緊張，例如在發佈會中，你覺得難以流暢地說話? 其實每一個人說話時也會有停頓的時候，到底我們如何分辨「口吃」和正常的不流暢呢？ 孩子到底是口吃還是因語言能力較弱而在找字呢？是否長大後自然會沒有口吃的問題？ 言語治療師可以如何幫助受口吃困擾的小孩和成人呢？

This talk begins with an overview of the interconnection between literature and philosophy in modern Chinese literature. Then, it probes into the three existentialist allegories in Fortress Besieged (1947), a philosophical novel written by Qian Zhongshu, a polyglot scholar of East-East comparative literature and philosophy. The novel’s overarching allegory, i.e., a fortress besieged, will be compared in juxtaposition with several philosophical allegories about the mutability and limitations of human life in Western philosophy. This talk concludes with a reflection on the seminal influence of this novel in contemporary Chinese society where “fortress besieged” has become an everyday word referring to one’s existential crisis.

宣統年間（1909-1911），袁世凱（1859-1916）在攝政王載灃排擠下歸隱彰德府洹上村，與門生故舊唱和，以示無心世務。這些詩作被袁氏次子袁克文（1890-1931）輯錄於《圭塘唱和詩》中，於宣統二年（1910）刊印，其中袁氏詩作共十三題十五篇。1940年代，長子袁克定（1878-1958）將袁世凱當年親筆謄鈔之詩稿影印出版，額曰《洹村逸興》。比對二書之篇目，《圭塘》諸本有袁氏詩作五篇不見於《洹村逸興》。實際上，該五篇之謄抄稿仍與《洹村逸興》之原件共同收藏於社科院近代史所；克定當日不收入書中，蓋因稿上頗有無名氏批點文字，公之於眾可能影響乃父形象。這些批點文字當係某位幕僚所為，內容為修改建議；然參《圭塘》諸本，可知袁世凱對建議幾乎全未採納。本文著眼於五篇詩稿及其批點文字，以討論原詩與修改建議如何優劣互見，乃至這輯詩歌與當時政局之微妙關係。

編修地方志為中華民族悠久而獨特的文化傳統，至今已有2000多年歷史。中國方志有始於《山海經》、《尚書‧禹貢》和《周禮》這三種說法。「國有史，地有志」，「方志」和「歷史」在中國史學傳統上，有同源異流的密切關係。是次講座根據歷來中國地方志的原始資料和方志學著述，討論「志」與「史」的異同，並疏理中國舊方志和中國新方志在「存史」及「資政」方面的經驗，並就地方志對歷史研究的當代意義提出建議。

古代中國幅員遼闊，習俗各異，如何實行統一管理是一大難題。秦朝用嚴刑峻法移風易俗，激起東方社會的激烈反抗，很快歸於失敗。西漢初年郡國並行，允許東方王國在一定程度上從俗而治。但王國勢力太大，危及國家的統一，文景二帝不得不收奪諸侯王的自治權。為了避免重蹈亡秦覆轍，儒生們提出“德教”主張，其中又包含“以禮為治”和“以德化民”兩種方案。受其影響，武帝以後的朝廷政策繼續表現出大幅度搖擺，至漢末魏晉才確立了基本符合當時國情的治理模式。

清朝皇族婚入女子的財產權受到法律保障，但是皇族女子的財產權則缺乏法律保障，分產的機會也相對稀少。清朝公主出嫁後對於其陪嫁的人丁、動產與不動產並未擁有完整的所有權，僅擁有占有權、使用權與收益權，而不具備轉讓或出售的處分權，其後代對其亦無繼承權。本文以清代滿洲公主的陪嫁莊頭與壯丁為例，運用清代滿蒙漢文檔案材料和官書典籍，輔以其他二手研究文獻，以出嫁蒙古王公之清朝公主的收支為核心，並聚焦於其妝奩上，探討其財產的所有權、管理機制與公主薨逝後的轉讓情況。最後透過研究公主在崇奉藏傳佛教上的花費，說明清朝公主如何在清朝治理蒙古的政策中起到重要作用。

有關《穆天子傳》周穆王西行地理的研究多矣，然自古未有定論。本研究以顧頡剛的實據地理與神話地理二重結構為理論框架，結合傳世文獻、出土資料與地理實查資料，重探《穆傳》的地理空間。針對有實據之部的地理，本研究強調以當代資料作為地理重構的依據，並發現其主要以戰國早期的晉南及其鄰近地區為核心。針對神話空間，則著重分析其「理性化」的創作思維及其反映的歷史地理脈絡，包含其領土型態、中國觀、世界觀以及交通地理背景。基於上述的歷史地理重構與分析，本研究進一步探討《穆傳》的體裁、國家主體、成書年代、資料依據、作者與讀者以及文本性質，期許對於這部高度爭議的奇書帶來新的認識。

本演講的出發點是《西廂記》在法國的傳播與接受，從儒蓮、巴贊的戲曲翻譯談起，說明《西廂記》故事如何被十九世紀的歐陸漢學家理解，進而創發出風貌各異的紅娘、鶯鶯與張生等角色類型。本演講也將觸及晚清民初在法國的外交官、留學生，說明他們如何譯介或改編《西廂記》，並與法國文學界激盪出不同模式的文化交流。由此延伸出的議題是熊式一、夏志清等身處英美國家的華人學者，淺析他們如何將《西廂記》置放於知識傳播的脈絡下，讓《西廂記》在二十世紀成為西方讀者認識中國戲曲的重要媒介之一。

中國戲曲源自新石器時代的巫術儀式，經歷漢代百戲、唐代戲弄和北宋雜劇，在北宋末融匯了多種形式的演出藝術、民歌、文人曲子及多種演唱文類，發展成戲曲鼻祖「南戲」。粵劇是清代地方劇種百花齊放的產品，既保留着近乎巫術儀式的《祭白虎》，也承傳着崑曲牌子、秦腔梆子、徽劇二黃、宋明南戲和元雜劇的劇目，堪稱中國戲曲的縮影。本講座概述當代香港粵劇的傳承狀況和中國戲曲的歷史面貌，從中探討粵劇如何保留和發展傳統戲曲的元素。講座將論及粵劇神功戲的演出、《祭白虎》儀式、戲班結構、行當、劇目題材、唱腔特點和傳承。

晚清時期英雄傳記風行一時，引發英雄崇拜的熱潮。但是此時所謂「傳記」，其實是融合諸多資源形構而成的新文類。《意大利建國三傑傳》作為晚清英雄傳記的代表作，充分展示了這一特徵。梁啟超借鑑明治政治小說的多種書寫模式，又援引本土小說的要素，將意大利建國史轉化為中國未來命運的預言，將意大利建國三傑刻畫為智、仁、勇的化身，將兒女情長俠義精神引入傳記書寫。正是由於梁啟超自出機杼的創造與轉化，此類英雄傳記廣受讀者歡迎，成為晚清文學文化史上的典範作品。

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.

Staying F.O.C.U.S.E.D!
Learn BETTER. Learn FASTER. Learn MORE than you are used to.
To learn more about the idea of the “ecosystem” that we built around the FOCUSED philosophy and its accompanying 7 colourful dice framework, please visit the FOCUSED homepage.
Most problems, issues, and challenges remain unsolved because we end up resorting to our past habitual attempts without being mindful of new ways of thinking and new ways of doing. This video will showcase an innovative new strategic thinking framework that is designed to make you think more deeply and peripherally about your organization's unsolved problems, and in the process, open up alternatives not contemplated before.
This video illustrates the F.O.C.U.S.E.D. Dice framework, to help open your thinking about complex issues. Each letter represents different key behaviors:
"F" - Bring Fresh Perspective
"O" - Think, feel and act like an Owner/ Manager
"C" - Show Connected-thinking
"U" - Have a Sense of Urgency
"S" - Show Team SPIRIT

We investigate reversal and recirculation for the stationary Prandtl equations. Reversal describes the solution after the Goldstein singularity, and is characterized by regions in which u > O and u < 0. The classical point of view of regarding the Prandtl equations as an evolution equation in x completely breaks down since u changes sign. Instead, we view the problem as a quasilinear, mixed-type, free-boundary problem. This is a joint work with Sameer Iyer.

Models arising in biology are often written in terms of Ordinary Differential Equations. The celebrated paper of Kermack-McKendrick (19271, founding mathematical epidemiology, showed the necessity to include parameters in order to describe the state of the individuals, as time elapsed after infection. During the 70s, many mathematical studies were developed when equations are structured by age, size, more generally a physiological trait. The renewal, growth-fragmentation are the more standard equations. The talk will present structured equations, show that a universal generalized relative entropy structure is available in the linear case, which imposes relaxation to a steady state under non-degeneracy conditions. In the nonlinear cases, it might be that periodic solutions occur, which can be interpreted in biological terms, e.g., as network activity in the neuroscience. When the equations are conservation laws, a variant of the Monge-Kantorovich distance (called Fortet-Mourier distance) also gives a general non-expansion property of solutions.

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.

Adaptive computation is of great importance in numerical simulations. The ideas for adaptive computations can be dated back to adaptive finite element methods in 1970s. In this talk, we shall first review some recent development for adaptive methods with some application. Then, we will propose a deep adaptive sampling method for solving PDEs where deep neural networks are utilized to approximate the solutions. In particular, we propose the failure informed PINNs (FI-PINNs), which can adaptively refine the training set with the goal of reducing the failure probability. Compared with the neural network approximation obtained with uniformly distributed collocation points, the proposed algorithms can significantly improve the accuracy, especially for low regularity and high-dimensional problems.

We introduce a Dimension-Reduced Second-Order Method (DRSOM) for convex and nonconvex (unconstrained) optimization. Under a trust-region-like framework, our method preserves the convergence of the second-order method while using only Hessian-vector products in two directions. Moreover; the computational overhead remains comparable to the first-order such as the gradient descent method. We show that the method has a local super-linear convergence and a global convergence rate of 0(∈-3/2) to satisfy the first-order and second-order conditions under a commonly used approximated Hessian assumption. We further show that this assumption can be removed if we perform one step of the Krylov subspace method at the end of the algorithm, which makes DRSOM the first first-order-type algorithm to achieve this complexity bound. The applicability and performance of DRSOM are exhibited by various computational experiments in logistic regression, L2-Lp minimization, sensor network localization, neural network training, and policy optimization in reinforcement learning. For neural networks, our preliminary implementation seems to gain computational advantages in terms of training accuracy and iteration complexity over state-of-the-art first-order methods including SGD and ADAM. For policy optimization, our experiments show that DRSOM compares favorably with popular policy gradient methods in terms of the effectiveness and robustness.

Convex Matrix Optimization (MOP) arises in a wide variety of applications. The last three decades have seen dramatic advances in the theory and practice of matrix optimization because of its extremely powerful modeling capability. In particular, semidefinite programming (SP) and its generalizations have been widely used to model problems in applications such as combinatorial and polynomial optimization, covariance matrix estimation, matrix completion and sensor network localization. The first part of the talk will describe the primal-dual interior-point methods (IPMs) implemented in SDPT3 for solving medium scale SP, followed by inexact IPMs (with linear systems solved by iterative solvers) for large scale SDP and discussions on their inherent limitations. The second part will present algorithmic advances for solving large scale SDP based on the proximal-point or augmented Lagrangian framework In particular, we describe the design and implementation of an augmented Lagrangian based method (called SDPNAL+) for solving SDP problems with large number of linear constraints. The last part of the talk will focus on recent advances on using a combination of local search methods and convex lifting to solve low-rank factorization models of SP problems.
