This approach, which initially started as a multidimensional ICA, later evolved into an independent subspace analysis with developments in theory and methodology.
Specifically, the increasingly evident and different perspectives in theory and methodology not only facilitate in-depth research, but also stimulate the establishment of societies and academic conferences dedicated to different discipline branches.
The weak disciplinary foundation mentioned by Fei mainly refers to the lack of accumulation in theory and methodology over the years, lack of comprehension and absorption of the relevant outcomes of international academia, and lack of theoretical innovation.
At that time, Chinese ethnologists had to come up with supportive standards and technical solutions in theory and methodology as the Chinese government had kicked off the work of ethnic recognition nationwide.
Since it was presented for the first time in the 1990s (Zeng et al. 1998a, b), seismic sedimentology has been improved in theory and methodology by many researchers and is playing an increasingly important role in oil and gas exploration and development (Posamentier 2002; Miall 2002; Zeng and Hentz 2004; Zhang et al. 2007; Zhu et al. 2009; Zeng 2010; Reijenstein et al. 2011; Hubbard et al. 2011).
These efforts in the last three decades represent the large-scale systematic introduction of Western ethnology (cultural anthropology) in both theory and methodology, following the upsurge of translations in the early twentieth century.
By applying Western ethnology to the in-depth investigation and research of Chinese society, it achieved innovations and development in both theory and methodology.
"We focus on research in action, so our students are well founded in theory and research methodology as they build up their portfolios.
Yunnan University, Peking University, Lanzhou University, Xiamen University and Sun Yat-Sen University, as well as 12 other universities with considerable strength in ethnology and anthropology have made outstanding achievements in the theory and methodology of ethnology (anthropology), historical ethnology, urban anthropology, and local ethnic studies.
