Solving the Author Problem of \ue2Dream of the Red Chamber\ue2 with the Writing Style Indicator
No full textThe question of whether the number of authors of \ue2Dream of the Red Chamber\ue2 is only one or not has been discussed extensively since 1750. To clarify the number of authors of the book, in this thesis, we take some ideas of previous studies and conduct experiments with machine learning classifiers with various features (word count, word frequency, sentence pattern, change points, etc.). Finally, we find that feature selection is more important than a classifier itself.
We figure out the property for revealing the nature of the writing habits of different authors, and formulating the writing style categories. We use CkipTagger of Academia Sinica in Taiwan to break words and give word-based labels, and then organize 61 kinds of words into 45 writing style categories. Our writing style categories could correctly distinguish the same type of books of different authors, but it is difficult to distinguish the same type of books of the same author. This result means that our writing style categories could correctly analyze the writing styles and distinguish the habits of different authors. In addition, to test the effectiveness of the writing style categories, we apply SVM (support vector machine) classifier and Tanimoto similarity to the experiments on the same type of books of the same author. The result shows that the writing style categories is more stable than other features. Then we perform three experiments of the same author from same books, the same author from different books, and different authors. These are carried out for 42 control group novels. Then the corresponding SVM accuracy and Tanimoto value range are obtained as the writing style indicator. Finally, we perform the same experiments on the first 80 episodes and the last 40 episodes of \ue2Dream of the Red Chamber\ue2. According to the experimental results, we conclude that the question of whether there is one or more than one authors in the entire book of \ue2Dream of the Red Chamber\ue2 is inconclusive. We cannot prove that there is only one author, and we cannot prove that there are multiple authors either.
Based on this study, we develope a web application that compares the writing style similarity of the two texts on the following website:

Diagonal Forms, Linear Algebraic Methods and Ramsey-Type Problems
No full textThis thesis focuses mainly on linear algebraic aspects of combinatorics. Let N_t(H) be an incidence matrix with edges versus all subhypergraphs of a complete hypergraph that are isomorphic to H. Richard M. Wilson and the author find the general formula for the Smith normal form or diagonal form of N_t(H) for all simple graphs H and for a very general class of t-uniform hypergraphs H.
As a continuation, the author determines the formula for diagonal forms of integer matrices obtained from other combinatorial structures, including incidence matrices for subgraphs of a complete bipartite graph and inclusion matrices for multisets.
One major application of diagonal forms is in zero-sum Ramsey theory. For instance, Caro's results in zero-sum Ramsey numbers for graphs and Caro and Yuster's results in zero-sum bipartite Ramsey numbers can be reproduced. These results are further generalized to t-uniform hypergraphs. Other applications include signed bipartite graph designs.
Research results on some other problems are also included in this thesis, such as a Ramsey-type problem on equipartitions, Hartman's conjecture on large sets of designs and a matroid theory problem proposed by Welsh.</p
Optimality and limitations of audio-visual integration for cognitive systems
No full textMultimodal integration is an important process in perceptual decision-making. In humans, this process has often been shown to be statistically optimal, or near optimal: sensory information is combined in a fashion that minimizes the average error in perceptual representation of stimuli. However, sometimes there are costs that come with the optimization, manifesting as illusory percepts. We review audio-visual facilitations and illusions that are products of multisensory integration, and the computational models that account for these phenomena. In particular, the same optimal computational model can lead to illusory percepts, and we suggest that more studies should be needed to detect and mitigate these illusions, as artifacts in artificial cognitive systems. We provide cautionary considerations when designing artificial cognitive systems with the view of avoiding such artifacts. Finally, we suggest avenues of research toward solutions to potential pitfalls in system design. We conclude that detailed understanding of multisensory integration and the mechanisms behind audio-visual illusions can benefit the design of artificial cognitive systems.

Design automation for circuit reliability and energy efficiency
No full textThis dissertation presents approaches to improve circuit reliability and energy efficiency from different angles, such as verification, logic synthesis, and functional unit design. A variety of algorithmic methods and heuristics are used in our approaches such as SAT solving, data mining, logic restructuring, and applied mathematics. Furthermore, the scalability of our approaches was taken into account while we developed our solutions.
Experimental results show that our approaches offer the following advantages: 1) SAT-BAG can generate concise assertions that can always achieve 100% input space coverage. 2) C-Mine-DCT, compared to a recent publication, can achieve compatible performance with an additional 8% energy saving and 54x speedup for bigger benchmarks on average. 3) C-Mine-APR can achieve up to 13% more energy saving than C-Mine-DCT while confronting designs with more common cases. 4) CSL can achieve 6.5% NBTI delay reduction with merely 2.5% area overhead on average. 5) Our modulo functional units, compared to a previous approach, can achieve a 12.5% reduction in area and a 47.1% reduction in delay for a 32-bit mod-3 reducer. For modulo-15 and above, all of our modulo functional units have better area and delay than their previous counterparts.Submission published under a 24 month embargo labeled 'U of I Access', the embargo will last until 2019-12-01The student, Chen-Hsuan Lin, accepted the attached license on 2017-12-05 at 13:54.The student, Chen-Hsuan Lin, submitted this Dissertation for approval on 2017-12-05 at 14:15.This Dissertation was approved for publication on 2017-12-05 at 15:38.DSpace SAF Submission Ingestion Package generated from Vireo submission #11865 on 2018-03-13 at 09:56:58Made available in DSpace on 2018-03-13T15:25:27Z (GMT).

Translocal imagination of Hong Kong connections: the shifting of Chow Yun-Fat's star image since 1997
No full textAnyone who is interested in Hong Kong cinema must be familiar with one name: Chow Yun-fat (b. 1955). He rose to film stardom in the 1980s when Hong Kong cinema started to attract global attention beyond East Asia. During his early screen career, Chow established a star image as an urban citizen of modern Hong Kong through films such as A Better Tomorrow/Yingxiong bense (John Woo, 1986), City on Fire/Longhu fengyun (Ringo Lam, 1987), All About Ah-Long/A Lang de gushi (Johnnie To, 1989), God of Gamblers/Du shen (Wong Jing, 1989), and Hard Boiled/Lashou shentan (John Woo, 1992)
Review paper: gender competencies in the medical curriculum: addressing gender bias in medicine
No full textGender inequalities in health and gender bias in medicine are interrelated challenges facing health care providers and educators. Women and girls are disadvantaged in accessing health care because of their low social status and unequal treatment in medical care. Gender bias has long been inherent in clinical practice, medical research, and education. This can be traced to the medical curriculum that shapes the perceptions, attitudes, and behavior of the future doctor. The author advocates medical curricula change to address gender inequalities in health and gender bias in medicine. She analyses the reasons for integration of gender competencies in the medical curriculum, discusses what gender competencies are, and reviews ways to in-build gender competencies and their assessment. Efforts to change and gender sensitize medical curricula in
developed and developing countries are also reviewed. The review hopes to contribute to strategic
medical curriculum reform, which would lead to gender-sensitive health services and equity in health

No full textEchoing the recommendations from the World Health Organization (WHO) Traditional Medicine Strategy 2014-23, the concept of evidence-based healthcare (EBHC) was incorporated into the integration of traditional and complementary medicine (T&CM) with national health system.This thesis investigated how the use of EBHC approach guided the integration of T&CM with the national health system in Hong Kong context. As Chinese medicine (CM) is a major type of T&CM in Hong Kong, four studies were conducted to explore the integration from three perspectives related to CM service delivery, namely service standards, health information and health workforce, within the Hong Kong health system.Firstly, to improve the standard of CM service, consensus on recommending evidence-based CM interventions for cancer palliative care were built among twelve Hong Kong clinical experts via the GRADE-ADOLOPMENT approach. Three out of seven evidence-based interventions reached positive consensus as service recommendations. These recommendations were i) acupuncture and ii) acupressure for reducing fatigue among palliative cancer patients; and iii) moxibustion for reducing nausea and vomiting among patients receiving chemotherapy.Secondly, to guide future investment in the development of evidence-based health information, CM clinical research questions were prioritized by twelve international experts in cancer palliative care using a two-round Delphi survey. Eight research priorities reached positive consensus after the two-round survey. Six of them focused on acupuncture and related therapies for pain, fatigue, insomnia, anxiety, xerostomia, paresthesia and dysesthesia while two related to Chinese herbal medicine (CHM) for constipation and anemia.Thirdly, given the Chinese medicine practitioner (CMP) workforce play an important role in determining the use of evidence in clinical practice, individual qualitative face-to-face interviews were performed to explore their beliefs and attitudes of applying evidence-based synopses of systematic reviews (SRs) and randomized controlled trials (RCTs) in routine practice (n=15). Analysis of the interviews identified eleven constructs and sub-constructs within four Consolidated Framework for Implementation Research (CFIR) domains: intervention characteristics, outer setting, inner setting and characteristics of individuals. Facilitators which promoted the application of results from synopses of clinical evidence in CMPs’ routine practice included adaptability, external policy and incentives, and leadership engagement while barriers included complexity, culture, available resources, knowledge and beliefs about the intervention. The remaining four constructs acted as both barriers and facilitators.Fourthly, to address some of the barriers described above, an EBHC education workshop was tailored for Hong Kong CMPs. CMPs who completed the workshop (n=59) demonstrated significant improvements in the attitude and knowledge domains of the Evidence-based Practice Questionnaire (EPQ). Significant improvements were also observed in the attitude, perceived behavioural control, decision making, and intention and behaviour domains of the Evidence-based Practice Inventory (EPI).To conclude, this thesis suggests the following policy recommendations: i) to design theory-based customized implementation strategies for promoting the implementation of evidence-based CM service recommendations; ii) to invest in the identified clinical research priorities which helps reduce research waste; iii) to incorporate EBHC education into current CMP curricula, and iv) to disseminate synopses of existing clinical evidence via the public access website.為促進香港中醫藥的發展，香港特區政府遵循《世界衛生組織傳統醫學戰略2014至2023年》的重點方向，以「循證醫學」為本推動本地中西醫結合的政策和措施。本論文試利用概念框架，把中醫與香港醫療系統以「循證醫學」的方式結合，並從醫療服務標準、健康衛生資訊及人力資源規劃三方面，探討如何實踐中西醫結合臨床證據的應用及研究。本論文的第一部份邀請了12名香港專家，包括西醫、中醫和護士，進行Delphi專家問卷，透過GRADE-ADOLOPMENT方法制訂本地中醫在癌症紓緩治療的臨床建議，旨在提高中醫服務標準。結果顯示，達成專家共識的臨床建議如下: 使用針灸或穴位按摩改善疲勞症狀，以及艾灸改善化療引起的噁心和嘔吐。第二部份則邀請了12名國際專家，包括西醫、中醫、護士及臨床研究方法學家，參與Delphi專家問卷，確定中醫在癌症紓緩治療領域的優先臨床研究課題，旨在提供更多具實證的健康資訊。結果表明，在有限的研究資源下，我們應先進行臨床研究，探討針灸及相關療法能否改善正接受癌症紓緩治療患者的症狀。由於中醫師在應用臨床證據上扮演著重要的角色，因此第三部份邀請了15名香港中醫師，進行面對面訪談，以探討他們對在臨床上應用相關概要的看法。結果指出，應用概要之主要障礙為中醫師對「循證醫學」的認知不足，而且缺乏相關培訓，以致無法掌握其應用，甚至存在偏見。基於第三部份的結果，本論文的第四部份向59名香港中醫師提供「循證醫學」實踐證書課程。透過網上問卷評估發現，課程可有效改善他們對「循證醫學」的認知及態度。總的而言，本論文提供下列政策建議，從中醫方面推廣以「循證醫學」為本的中西醫結合發展:一. 研究實踐中醫臨床建議的利弊，再訂立合適的實施方案;二. 為減少研究浪費，未來的研究資源應著重分配在已確定的中醫優先臨床研究課題;三. 可考慮將「循證醫學」實踐證書課程納入目前的中醫常規培訓中;四. 以及，在網頁上發放基於現有中西醫結合臨床證據的概要，供公眾人士瀏覽。Wong, Hoi Lam Charlene."November 2019."Ph.D. Chinese University of Hong Kong 2020.Includes bibliographical references (leaves 146-162).Abstracts and appendix 4 also in Chinese.Title from PDF title page (viewed on September 6, 2022).Wong, Hoi Lam Charlene
