  • Chieftains Into Ancestors: Imperial Expansion and Indigenous Society in Southwest China
    1 Chieftains into Ancestors: Imperial Expansion and Indigenous Society in Southwest China. David Faure and Ho Ts’ui-p’ing, editors. Vancouver and Toronto: University of British Columbia Press, 2013. ISBN: 9780774823692 The scholars whose essays appear in this volume all attempt, in one way or another, to provide a history of southern and southwestern China from the perspective of the people who lived and still live there. One of the driving forces behind the impressive span of research across several cultural and geographical areas is to produce or recover the history(ies) of indigenous conquered people as they saw and experienced it, rather than from the perspective of the Chinese imperial state. It is a bold and fresh look at a part of China that has had a long-contested relationship with the imperial center. The essays in this volume are all based on extensive fieldwork in places ranging from western Yunnan to western Hunan to Hainan Island. Adding to the level of interest in these pieces is the fact that these scholars also engage with imperial-era written texts, as they interrogate the different narratives found in oral (described as “ephemeral”) rituals and texts written in Chinese. In fact, it is precisely the nexus or difference between these two modes of communicating the past and the relationship between the local and the central state that energizes all of the scholarship presented in this collection of essays. They bring a very different understanding of how the Chinese state expanded its reach over this wide swath of territory, sometimes with the cooperation of indigenous groups, sometimes in stark opposition, and how indigenous local traditions were, and continue to be, reified and constructed in ways that make sense of the process of state building from local perspectives.

  • Narrative Inquiry Into Chinese International Doctoral Students
    Volume 16, 2021 NARRATIVE INQUIRY INTO CHINESE INTERNATIONAL DOCTORAL STUDENTS’ JOURNEY: A STRENGTH-BASED PERSPECTIVE Shihua Brazill Montana State University, Bozeman, [email protected] MT, USA ABSTRACT Aim/Purpose This narrative inquiry study uses a strength-based approach to study the cross- cultural socialization journey of Chinese international doctoral students at a U.S. Land Grant university. Historically, we thought of socialization as an institu- tional or group-defined process, but “journey” taps into a rich narrative tradi- tion about individuals, how they relate to others, and the identities that they carry and develop. Background To date, research has employed a deficit perspective to study how Chinese stu- dents must adapt to their new environment. Instead, my original contribution is using narrative inquiry study to explore cross-cultural socialization and mentor- ing practices that are consonant with the cultural capital that Chinese interna- tional doctoral students bring with them. Methodology This qualitative research uses narrative inquiry to capture and understand the experiences of three Chinese international doctoral students at a Land Grant in- stitute in the U.S. Contribution This study will be especially important for administrators and faculty striving to create more diverse, supportive, and inclusive academic environments to en- hance Chinese international doctoral students’ experiences in the U.S. Moreo- ver, this study fills a gap in existing research by using a strength-based lens to provide valuable practical insights for researchers, practitioners, and policymak- ers to support the unique cross-cultural socialization of Chinese international doctoral students. Findings Using multiple conversational interviews, artifacts, and vignettes, the study sought to understand the doctoral experience of Chinese international students’ experience at an American Land Grant University.

Chen Submitted to the graduate degree program in Art History and the Graduate Faculty of the University of Kansas in partial fulfillment of the requirements for the degree of Doctor of Philosophy. ________________________________ Chairperson Marsha Haufler ________________________________ Amy McNair ________________________________ Sherry Fowler ________________________________ Jungsil Jenny Lee ________________________________ Keith McMahon Date Defended: May 13, 2016 The Dissertation Committee for Janet C. Chen certifies that this is the approved version of the following dissertation: REPRESENTING TALENTED WOMEN IN EIGHTEENTH-CENTURY CHINESE PAINTING: THIRTEEN FEMALE DISCIPLES SEEKING INSTRUCTION AT THE LAKE PAVILION ________________________________ Chairperson Marsha Haufler Date approved: May 13, 2016 ii Abstract As the first comprehensive art-historical study of the Qing poet Yuan Mei (1716–97) and the female intellectuals in his circle, this dissertation examines the depictions of these women in an eighteenth-century handscroll, Thirteen Female Disciples Seeking Instructions at the Lake Pavilion, related paintings, and the accompanying inscriptions. Created when an increasing number of women turned to the scholarly arts, in particular painting and poetry, these paintings documented the more receptive attitude of literati toward talented women and their support in the social and artistic lives of female intellectuals. These pictures show the women cultivating themselves through literati activities and poetic meditation in nature or gardens, common tropes in portraits of male scholars. The predominantly male patrons, painters, and colophon authors all took part in the formation of the women’s public identities as poets and artists; the first two determined the visual representations, and the third, through writings, confirmed and elaborated on the designated identities.
