  • The Significance and Inheritance of Huang Di Culture
    ISSN 1799-2591 Theory and Practice in Language Studies, Vol. 8, No. 12, pp. 1698-1703, December 2018 DOI: http://dx.doi.org/10.17507/tpls.0812.17 The Significance and Inheritance of Huang Di Culture Donghui Chen Henan Academy of Social Sciences, Zhengzhou, Henan, China Abstract—Huang Di culture is an important source of Chinese culture. It is not mechanical, still and solidified but melting, extensible, creative, pioneering and vigorous. It is the root of Chinese culture and a cultural system that keeps pace with the times. Its influence is enduring and universal. It has rich connotations including the “Root” Culture, the “Harmony” Culture, the “Golden Mean” Culture, the “Governance” Culture. All these have a great significance for the times and the realization of the Great Chinese Dream, therefore, it is necessary to combine the inheritance of Huang Di culture with its innovation, constantly absorb the fresh blood of the times with a confident, open and creative attitude, give Huang Di culture a rich connotation of the times, tap the factors in Huang Di culture that fit the development of the modern times to advance the progress of the country and society, and make Huang Di culture still full of vitality in the contemporary era. Index Terms—Huang Di, Huang Di culture, Chinese culture I. INTRODUCTION Huang Di, being considered the ancestor of all Han Chinese in Chinese mythology, is a legendary emperor and cultural hero. His victory in the war against Emperor Chi You is viewed as the establishment of the Han Chinese nationality. He has made great many accomplishments in agriculture, medicine, arithmetic, calendar, Chinese characters and arts, among which, his invention of the principles of Traditional Chinese medicine, Huang Di Nei Jing, has been seen as one of the greatest contributions to Chinese medicine.

    Adoption of Aspiration Feature in Sino-Korean Phonology Sun-Mi Kim A dissertation submitted in partial fulfillment of the requirements for the degree of Doctor of Philosophy University of Washington 2015 Reading Committee: Zev Handel, Chair Ellen Kaisse Soohee Kim Program Authorized to Offer Degree: Asian Languages and Literature ©Copyright 2015 Sun-Mi Kim Abstract Adoption of Aspiration Feature in Sino-Korean Phonology Sun-Mi Kim Chair of the Supervisory Committee: Professor Zev Handel Department of Asian Languages and Literature This dissertation examines the adoption of aspiration feature in Sino-Korean character readings. In broad usage, the term Sino-Korean refers to Chinese loanwords in Korean, but in this dissertation, it is used for a phonological system of Chinese-character readings (or pronunciation) derived from Middle Chinese. Although most sound correspondences between Sino-Korean and Middle Chinese are quite regular, some phonological features of Middle Chinese have been adopted irregularly into Sino-Korean, and Sino-Korean (SK) readings with aspiration discrepancy are part of this broader phenomenon of irregular SK readings. It is generally assumed that both the Chinese and Korean languages had voiceless aspirated stops and voiceless unaspirated stops at the time Chinese characters were adopted in the Korean peninsula. If that is indeed the case, a regular correspondence between Middle Chinese (MC) and SK is expected between the two languages. However, there are many cases where the aspiration feature shows irregular correspondence. Some SK readings with an unaspirated initial in their MC counterpart have an aspirated initial, while other SK readings with an aspirated initial in their MC counterpart have an unaspirated initial.

  • Male Names of Women and Female Names of Men in the Chinese Society Irena Kałużyńska
    ONOMÀSTICA BIBLIOTECA TÈCNICA DE POLÍTICA LINGÜÍSTICA Male Names of Women and Female Names of Men in the Chinese Society Irena Kałużyńska DOI: 10.2436/15.8040.01.81 Abstract The paper discusses some Chinese given names that apparently indicate the sex of their bearers. In China there have never been any strict linguistic rules concerning the gender-specific differentiation of given names, as the Chinese language does not have a grammatical gender, and the gender usually is a covert category. However, there is a group of given names strictly complying with the most common naming convention, i.e. that a name overtly indicates the sex of the person named. These are Chinese female given names with “female” terms written in characters with the graphical marker of “femininity”, and male names with typical “male” terms, especially general terms for men, terms of address, kinship and rank. In most cases the occurrence of such a term in a name indicates that the bearer of the name is a woman or a man. The cases of the inverse use of the terms reveal the additional significance of such formed names, as commendatory or counter-commendatory names. ***** Introduction The meaningfulness of names plays an important social and cultural role in the Chinese naming system. Given names are formed individually, and they are mostly semantically transparent. The approach to names, as being not only labels helpful in the identification of people but almost real or desired facts, has caused that through personal names the Chinese express their culture-oriented opinions and expectations. Gender stereotypes have had an enormous impact on various aspects of the family and social life, and they have also influenced personal naming.

The names also reflect the beliefs and religion of Singapore Chinese. More significantly, a change of identity and representation is reflected in the names of earlier settlers and Singapore Chinese today. This paper aims to show the general naming traditions of Chinese in Singapore as well as a change in ideology and trends due to globalization. Keywords Singapore, Chinese, names, identity, beliefs, globalization. 1. Introduction When parents choose a name for a child, the name necessarily reflects their thoughts and aspirations with regards to the child. These thoughts and aspirations are shaped by the historical, social, cultural or spiritual setting of the time and place they are living in whether or not they are aware of them. Thus, the study of names is an important window through which one could view how these parents prefer their children to be perceived by society at large, according to the identities, roles, values, hierarchies or expectations constructed within a social space.

  • A Comparison of the Korean and Japanese Approaches to Foreign Family Names
    15 A Comparison of the Korean and Japanese Approaches to Foreign Family Names JIN Guanglin* Abstract There are many foreign family names in Korean and Japanese genealogies. This paper is especially focused on the fact that out of approximately 280 Korean family names, roughly half are of foreign origin, and that out of those foreign family names, the majority trace their beginnings to China. In Japan, the Newly Edited Register of Family Names (新撰姓氏錄), published in 815, records that out of 1,182 aristocratic clans in the capital and its surroundings, 326 clans—approximately one-third—originated from China and Korea. Does the prevalence of foreign family names reflect migration from China to Korea, and from China and Korea to Japan? Or is it perhaps a result of Korean Sinophilia (慕華思想) and Japanese admiration for Korean and Chinese cultures? Or could there be an entirely distinct explanation? First I discuss premodern Korean and ancient Japanese foreign family names, and then I examine the formation and characteristics of these family names. Next I analyze how migration from China to Korea, as well as from China and Korea to Japan, occurred in their historical contexts. Through these studies, I derive answers to the above-mentioned questions. Key words: family names (surnames), Chinese-style family names, cultural diffusion and adoption, migration, Sinophilia in traditional Korea and Japan 1 Foreign Family Names in Premodern Korea The precise number of Korean family names varies by record. The Geography Annals of King Sejong (世宗實錄地理志, 1454), the first systematic register of Korean family names, records 265 family names, but the Survey of the Geography of Korea (東國輿地勝覽, 1486) records 277.

Dissertation Title: Followers Creative Self-efficacy and Idea Generation in Entrepreneurial Settings: Leader Narcissism and Leader Humility as Joint Moderators Committee: Brian Anderson (Chair), Jeff Hornsby, Mark Perry, and Ishrat Ali Status: Dissertation proposal defense scheduled in July 2019. Abstract: Based on social-cognitive theory and a paradox perspective, this dissertation explores how leader narcissism and leader humility together moderate the influence of domain- specific self-efficacy on the type-specific innovative work behavior in entrepreneurial settings. This multilevel framework answers the repeated calls for theorizing and examining the joint effects of multiple leader traits. It offers novel insights to understand the interaction effects of leader humility and narcissism in the entrepreneurial context. By focusing on idea generation, I clarify areas of ambiguity in prior research on innovative work behavior. I used a three-phase design for this dissertation. First, I assessed the psychometric properties of the focal constructs with a sample of 98 students. I further refined the measures and checked their consistency with 380 participants from Amazon M-Turk. Consistent results from Phase 1 and Phase 2 showed the scales were reliable and valid.
