Chen Hansheng was not only a pioneer of modern Chinese social science, remembered for the village studies he organized by teams of researchers in the 1930s. He was also a political operative whose career as an underground and aboveground Communist activist spanned the twentieth century and the globe. This book draws on unique interviews, beginning in 1979, with Chen himself, his family and associates, along with an exhaustive examination of documents, writings, and archives, to build a rounded portrait of Chen, the man, and his world. -------------- “Stephen MacKinnon’s lifetime study of eminent social scientist and Communist Chen Hansheng makes for an absorbing, thrilling, and illuminating read. This product of decades of researching Chen, and of years of discussions with him, MacKinnon shows us how one enterprising and creative scholar became dedicated to the cause, worked for it, and then ended his life sad and angry about what became of the Chinese Communist Party in power.” —Han

With the increasing number of complaints and court cases relating to healthcare disputes, healthcare practitioners (HCPs) are now facing more challenges and dilemmas in their daily practices. This book is unique in that most chapters are written jointly by two authors: one with legal training and one with a healthcare background. The balanced view offered thus allows readers to gain a thorough understanding of the concepts presented. Although most of the examples and scenarios are specific to medical doctors, the basic principles and ethical considerations as well as the enforcement of laws and regulations are, with some modifications, equally applicable to other HCPs, such as dentists, nurses, midwives, etc. Readers interested in healthcare law and ethics from numerous fields and stages of training, including legal and healthcare practitioners, trainees, postgraduate researchers and undergraduate students, will find this book both informative and practical as an aid to their work and

◎This is the Part-One (Radical Index - Stroke No. 1-2) of Twelve printouts from the on-line dictionary that is currently under developing. ◎This unprecedented, intelligent, convenient and useful Tool provides “Pin Yin” (spelled in English) of Traditional Chinese characters. ◎Along with Stroke-by-Stroke writings for each character’s Radical and additional strokes, it is possible to learn Chinese ubiquitously. The stroke-sequences for writing radical-characters are also included in a separate nineteen-page section with the order of radical stroke number and sequence. All the multiple ways of “Pin Yin” will also appear under multiple English letters. However, an unique sort key for the Last Name found in 百家姓 (the Hundred Family Surnames) is highlighted and used for grouping the same Last Name in Traditional Character with different Last Name in English. For example, 鄭 can be found as Cheng, Jeng and Zheng in all 3 places with Cheng marked as sort-key. Therefore, all 鄭s will be grouped u

Psychopathology: An Empathic Representational Approach retraces the foundations of classical phenomenological psychopathology and integrates them with modern ideas drawn from anthropology, cognitive neuroscience, computational science, and evolutionary biology to synthesize a comprehensive framework and provide fresh insights. This book explores how the scientific concepts of ‘information and representation’ can be used to understand subjective mental phenomena and integrate them in empathic clinical dialogues during interactions with patients. It explores key issues in clinical psychopathology coherently and systematically, illustrates advanced topics in an accessible manner using clinical case examples, metaphors and clarifying diagrams, and directly links advanced conceptual frameworks with pragmatic skills in the clinical dialogue process. This volume is aimed at a broad audience of mental health professionals, researchers, and students in psychiatry, psychology, and social work.

In Chinese Cinema: Identity, Power, and Globalization, a variety of scholars explore the history, aesthetics, and politics of Chinese cinema as the Chinese film industry grapples with its place as the second largest film industry in the world. Exploring the various ways that Chinese cinema engages with global politics, market forces, and film cultures, this edited volume places Chinese cinema against an array of contexts informing the contours of Chinese cinema today. The book also demonstrates that Chinese cinema in the global context is informed by the intersections and tensions found in Chinese and world politics, national and international co-productions, the local and global in representing Chineseness, and the lived experiences of social and political movements versus screened politics in Chinese film culture. This work is a pioneer investigation of the topic and will inspire future research by other scholars of film studies.

西西的動物詩，大部分是近年的新作，盡是奇思妙想，而民胞物與，充滿溫暖、關懷之情，明朗，親切，靈動，幽默，自有深意，寫來似跟動物通靈。總括而言，是為動物發聲，彼此平等、和平地相處，合而為「動物嘉年華」，並且邀來二十多位香港年輕畫家和插畫師參加盛會，每首詩配以不同的繪畫，畫風迥異，不拘一格，呈現多元異質。看西西的詩，看畫家們的詮釋，加上讀者自己的想像與理解，眾聲複調，文學藝術合該這般如此。西西的作品在華文世界膾炙人口，屢獲殊榮，曾獲美國紐曼華語文學獎，以及瑞典蟬獎，為香港獲國際詩獎的首位作家。這詩集是奇書《縫熊志》、《猿猴志》後，另一種動物書寫。 本書適合青少年，也適合喜歡文學藝術的成年。 Most of Xi Xi’s animal poems featured here are new works written during the past few years.

These poems could be described as bright and cheerful, approachable, clever and fluid, humourous, and deep with meaning, written as though the author is able to directly communicate with animals. Overall, they serve as a voice for animals, showing that they are able to coexist equally and peacefully, resulting in a “carnival of animals.” More than twenty young Hong Kong artists and illustrators have been invited to join this project, with each poem accompanie

The Sinological Development Charitable Foundation (SDCF) aspires to help spread 5,000 years of cultural history embedded in the Chinese Classics as a fundamental basis for understanding Chinese civilization. To that end, every year since 2016, the SDCF has provided intensive summer programs by which means scholars from across the globe are brought together in situ (in Hong Kong, Macau, Taiwan, and mainland China) to learn together and share their research into some of the most important topics in Chinese Studies. Over the last five years (2016–2020), candidates representing nations from Africa, the Americas, Europe, the Middle East, Russia, and other parts of Asia have embraced the SDCF program and its goals. This compendium is published to mark the milestone of five comprehensive programs completed successfully. It includes a sample of the best research by program participants from around the world, along with personal reflections and reflections by professors and tutors allied with

In Painting Architecture: Jiehua in Yuan China, 1271–1368, Leqi Yu has conducted comprehensive research on jiehua or ruled-line painting, a unique painting genre in fourteenth-century China. This genre relies on tools such as rulers to represent architectural details and structures accurately. Such technical consideration and mechanical perfection linked this painting category with the builder’s art, which led to Chinese elites’ belittlement and won Mongol patrons’ admiration. Yu suggests that painters in the Yuan dynasty made new efforts towards a unique modular system and an unsurpassable plain-drawing tradition. She argues that these two strategies made architectural paintings in the Yuan dynasty entirely different from their predecessors, as well as making the art form extremely difficult for subsequent painters to imitate.

Games help drive engagement, achieve goals, and ultimately promote development within a group. As such, it is important for group facilitators to be equipped with game skills to ensure a lively, vibrant, and motivated atmosphere. This book includes four theoretical essays by experienced game facilitators regarding the concept, practice sharing, and application skills of group game facilitation, as well as a collection of 100 practical group games covering ice-breaking, mutual understanding, group cooperation, and problem solving. This list of games is built on the experiences and contributions of the author and social work students.

Masculinity, fast-changing and regularly declared to be in the throes of crisis, is attracting more popular and scholarly debate in China than ever before. At the same time, Chinese literature since 1989 has been characterized as brimming with countercultural ‘attitude’. This book probes the link between literary rebellion and manhood in China, showing how male writers, as they critique the outcomes of decades of market reform, also ask the same question: how best to be a man in the new postsocialist order? In this first full-length discussion of masculinity in post-1989 Chinese literature, Pamela Hunt offers a detailed analysis of four contemporary authors in particular: Zhu Wen, Feng Tang, Xu Zechen, and Han Han. In a series of insightful readings, she explores how all four writers show the same preoccupation with the figure of the man on the edges of society. Drawing on longstanding Chinese and global models of maverick and marginal masculinity, and responding to a desire to retain

Sir Robert Ho Tung (1862–1954) is a compelling figure in Hong Kong history. He is regularly portrayed as the colony’s greatest philanthropist and wealthiest man of his day, the first Chinese to live on the Peak, and, at the end of his life, the ‘Grand Old Man of Hongkong’. The illegitimate son of a Chinese mother and European father, he was highly sensitive about his mixed heritage though he consistently made the most of his fate. He was a man perfectly in tune with his place and time, his success driven as much by his entrepreneurial talents as by his being Eurasian. This book shows him in all his immense variety—clerk with the Imperial Maritime Customs, chief compradore of Jardine Matheson, financial wizard, husband and lover, patriarch of a large family of five sons and eight daughters, loyal British subject but also, paradoxically, Chinese patriot. China’s president Yuan Shikai awarded him the Order of the Excellent Crop, and King George V knighted him. May Holdsworth’s thoughtful

This book, Chiang Yee and His Circle: Chinese Artistic and Intellectual Life in Britain, 1930–1950, celebrates the life and work of Chiang Yee (1903–1977), a Chinese writer, poet, and painter who made his home in London, England during the 1930s and 1940s. It examines Chiang’s relationship with his circle of friends and colleagues in the English capital, and assesses the work he produced during his sojourn there. This edited volume, with contributions from eleven distinguished scholars, tells a story of a Chinese intellectual community in London that up to now has been largely overlooked. It portrays a dynamic picture of the London-based émigré life during the years that led up to the war and during the conflict that was the catalyst for many of them moving on. In addition, the book broadens our understanding of cultural interactions between China and the West in Hampstead, one of the most vibrant artistic communities in London.

The ultimate goal of this thesis is to construct an optimal global portfolio with ETFs. We choose the iShares MSCI country index ETFs as our assets. We start with the calculation of correlation between these countries. We find out that there is potential benefit undertaking international diversification. While comparing with the former research, the potential benefit is smaller. We examine the effect of investing internationally of each country. And we can see that not all countries are benefit from international diversification. While considering international diversification, investors have to look at the characteristic of the domestic country to make decision. In the international level, we can see that the investment risk would decrease and the return would increase. And the marginal effect decreases. In our test, the return, risk and efficiency come stable after adding the 14th asset into the global portfolio. Therefore we construct our global portfolio with 13 assets. We can see

English novelist E.M. Forster wrote his last and best-loved work, A Passage to India, both as a paean to his love for India and as a tribute to the relationships he formed with Indians. Forster became entranced by the India of the Raj at a young age, and his love affair with the sub-continent, its princes, and peoples, was to last all his life. At his most socially transgressive, it was with Indians that Forster chose to connect and with whom he put into effect his belief in man’s duty to value friendship over state or ideology. His time in India was undoubtedly when he was at his most human and most vulnerable. At once a contemporary reflection on India’s rich history and a biographical retelling of Forster’s travels through the country in the early 1900s, Developing the Heart delves into the past to better understand the profound impact certain events and people had on his writing. In doing so, it allows readers to look on as Forster matures and softens over time in his behaviour

The crisis of masculinity surfaced and converged with the crisis of the nation in the late Qing, after the doors of China were forced open by Opium Wars. The power of physical aggression increasingly overshadowed literary attainments and became a new imperative of male honor in the late Qing and early Republican China. Afflicted with anxiety and indignation about their increasingly effeminate image as perceived by Western colonial powers, Chinese intellectuals strategically distanced themselves from the old literati and reassessed their positions vis-à-vis violence. In Mastery of Words and Swords: Negotiating Intellectual Masculinities in Modern China, 1890s–1930s, Jun Lei explores the formation and evolution of modern Chinese intellectual masculinities as constituted in racial, gender, and class discourses mediated by the West and Japan. This book brings to light a new area of interest in the “Man Question” within gender studies in which women have typically been the focus. To fully r

The origins of modern Daoism can be traced to the Church of the Heavenly Master (Tianshidao), reputedly established by the formidable Zhang Daoling. In 142 CE, according to Daoist tradition, Zhang was visited by the Lord on High, who named him his vicar on Earth with the title Heavenly Master. The dispensation articulated an eschatological vision of saving initiates—the pure, those destined to become immortals— by enforcing a strict moral code. Under evolving forms, Tianshidao has remained central to Chinese society, and Daoist priests have upheld their spiritual allegiance to Zhang, their now divinized founder. This book tells the story of the longue durée evolution of the Heavenly Master leadership and institution. Later hagiography credits Zhang Daoling’s great-grandson, putatively the fourth Heavenly Master, with settling the family at Longhushan (Dragon and Tiger Mountain); in time his descendants—down to the present contested sixty-fifth Heavenly Master living in Taiwan— made th

In War and Revolution in South China, Edward Rhoads recounts his childhood and early teenage years during the Sino-Japanese War and the early postwar years. Rhoads came from a biracial family. His father was an American professor while his Chinese mother was a typist and stenographer. In the late 1930s and the 1940s, the Rhoads family lived through the turbulent years in southern China and Hong Kong. The book follows Rhoads’ childhood in Guangzhou, his family’s evacuation to Hong Kong, his father’s internment and repatriation to the United States, and his and his mother’s flight to Free China. He recalls his reunion with family members in northern Guangdong Province in 1943, their retreat to China’s wartime capital of Chongqing, where his father worked for the American government, and how they returned to Guangzhou after the war. The Rhoads family then witnessed the socioeconomic recovery in the city and the regime change in 1949. The book ends with their departure from China to the Un

“Red and blue appear in stark contrast with one another on the map of America. But the even more profound divide is the alienation in our hearts.” This work is a striking analysis of the struggles faced by American society, written from the perspective of a Chinese professor of history who spent 60 years of his life in the US. As both an insider and outsider to this country, Cho-yun Hsu is able to perceive what many other Americans may take for granted, and it is this viewpoint—together with his decades of experience teaching history at the University of Pittsburgh—that make this work so unusual and worthwhile. This work analyzes American history through a wide range of topics, including culture, politics, economics, industrialization, class, ethnicity, the urban-rural divide, and more. Expertly analyzing the origins of the tension and conflict between different classes and ethnic groups in American society, this book seeks to offer a way forward from a humanistic perspective, in the

Appropriate for use by students at varying levels of competence, Burmese: A Cultural Approach provides a thorough and systematic introduction to the Burmese writing system in Part One and a series of true-to-life conversations in Part Two. Students with some prior knowledge of the spoken language but little familiarity with the Burmese script can use Part One to solidify their grasp of the Burmese sound system as well as its orthography. Intrepid beginners could also start their study of the language by making use of Part One. Doing so would mean making a slower start at formulating phrases as compared to using a romanization system but learners would gain a firmer foundation for the later—and eventually, faster—development of their speaking and reading skills. The conversations in Part Two are extensively annotated in order to illustrate grammatical patterns, characteristic turns of phrase, and typical habits of social interaction. True to an anthropological approach to language le

本書集結六篇論文（第一、三、四、六篇德文，第二篇西班牙文，第五篇義大利文），本書為因應時代變遷下的教育環境及學生職涯挑戰，在教學方法上所提出新的論述及建構。 This book contains essays by various teachers from different universities and departments with the aim of presenting modern teaching methods for the changed learning and study conditions on the basis of theoretical preliminary considerations. Language teachers at Taiwanese universities often encounter similar difficulties in designing lessons: students’ increasing frustration and lack of motivation. Many students experience a high level of frustration and demotivation; they cannot find future prospects in language studies. Confronted with reality of time-consuming internships, part-time jobs and life, many students become painfully aware that a linguistic degree won’t prepare them for later work or provides career opportunities. In addition, they realize their low language skills and life experiences. Aware of that problem, the language departments have to find new teaching methods and create curricula which
