The process included educational, pedagogical, judicial, liturgical and theological-rhetorical means and had significant, invaluable, and long lasting consequences. The province remains as a part of the Kingdom of Sweden. From a historical perspective, the process was fast and successful, even though some modem historians question the speediness of the process and thereby want to modify the picture of a fast and non-problematic Swedification or pseudo-indigenization process.展开更多

They depicted a clear blueprint for the relationship between China and Southeast Asia in the coming decades. China will more equally emphasize sovereignty, security and development interests and pay equal attention to land and maritime issues. The paper tries to summarize the features of China's Southeast Asian policy at present and the factors that influence the relations in the future.展开更多

In the context of this work the error is considered isotropic if it has spherical symmetry about the state of interest. The theoretical definition is given, as well the numerical approximation for practical purposes. The index is tested in some simple examples and the geometric distortion of the propagated error is studied for an inaccurate Shor 9-qubits correcting code.展开更多

Through the study in four aspects, namely, the pursuit of modem education, simple appearance, great leaders, and the ambassadors of culture, the author＇s research indicates that Chen＇s construction of＂new woman＂ has been influenced by complex historical and cultural forces such as the Chinese traditional culture, Western culture, and the iconoclastic spirit of ＂the New Culture Movement＂. Meanwhile, Chen＇s gender consciousness is also an important element. Moreover, Chen＇s pioneering standing and her own experiences of studying abroad makes her take the lead in conceiving women＇s leadership and their roles in global culture communications. In the late Qing and the early Republic, traditional values and norms of womanhood were severely challenged. Chen＇s construction of＂new woman＂ is her conscious effort to define a new womanhood and is an integral part of the ongoing exploration of Chinese women for modem womanhood. Through the examination of Chen＇s ＂new woman＂, this paper seeks to enrich our understanding of the complexity of modem Chinese women＇s exploration of modem womanhood.展开更多

The Chinese literati＇s yearning to become a part of＂the world,＂ and their endeavor to earn China a better position in the world, involved a hesitant process of exploration.展开更多

Based on near infrared （NIR） spectra of multiple samples, the genuine manufacturer of DEE J, e.g. Dong＇e Ejiao Co., Ltd., was accurately identified among 21 suppliers by the fingerprint method using Hotelling T2, distance to Model X （DModX）, and similarity match value （SMV） as dis- criminate criteria. Soft independent modeling of the class analogy algorithm led to a misjudgment ratio of 6.2%, suggesting that the fingerprint method is more suitable for manufacturer identification. For another important feature related to clinical efficacy of DEE J, storage time, the partial least squares-discriminant analysis （PLS-DA） method was applied with a satisfactory misjudgment ratio （15.6%） and individual prediction error around 1 year. Our results demonstrate that NIR spectra comprehensively reflect the essential quality information of DEE J, and with the aid of proper chemometric algorithms, it is able to identify genuine manufacturer and determine accurate storage time. The overall results indicate the promising potential of NIR spectroscopy as an effective quality control tool for DEEJ and other precious TCM products.展开更多

Ultimately, however, the country has been unable to complete the ＂transformation＂ of its political values. Its consciousness of superiority, dating back to the Meiji era, and its dream of being restored to the status of a ＂normal country＂ have distorted Japan＇s idea of the war and its interpretation of history. As a result, at the critical postwar moment when Japan most needed to develop a truthful view of its history, its national will expressed itself in the rejection of this possibility. Japan has manufactured Sino-Japanese friction and manipulated the United States, on the pretext of a supposed ＂China threat＂ into relaxing the constraints upon Japan, and has attempted to abandon the thought and deeds of the postwar international order. Not only has this repeatedly subverted the standards by which the intemational ＂left＂ and ＂right＂ assess Japan; it has also once again placed the Asia-Pacific region in a precarious position.展开更多
