Seismological research in Yunnan Province, China, and its tectonic implication between the Xianshuihe-Xiaojiang fault system and the Red River fault zone

The tectonic crosscutting relationship between the two most tectonic important Xianshuihe-Xiaojiang fault system (XFS) and the Red River fault zone (RRF) is a key basic problem but it is controversial now. These obscure further leads to a hot argument about the geodynamic model of the southeast margin of the Tibetan Plateau. In order to answer whether the XFS has cut across the RRF and extended southwardly, multiple seismological methods, including seismic relocation, b-value analysis, seismic energy, density study, focal mechanism inversion, and regional stress field research, are applied in the Yunnan Province area, China, where the XFS and the RRF intersects with each other. The results comprehensively demonstrate that the southern segment of the XFS has not been affected by the RRF, and it has continued for a length after crossing the RRF, but the Dian Bien Phu fault zone should not be an extension fault of the XFS. Along the SW direction, starting from the middle segment of the XFS, and cutting across the Qujiang fault, Shiping-Jianshui fault zone, RRF, Ailaoshan fault zone, Wuliangshan fault zone, and the southern section of the Daluo fault, the belt should be treated as the eastern boundary of the clockwise rotational in geodynamics model of the Tibetan Plateau in this study area. Based on these conclusion above and previous recognitions, a new geodynamic evolution model is proposed

Person-job fit and innovative behavior in new R&D institutions: the mediating effects of self-efficacy and job involvement on business decision-making

In recent years, new R&D institutions have emerged in China, distinguished from traditional research entities by their unique structure and objectives. This study explores the impact of person-job fit on the innovative behavior of 334 researchers within these institutions. Through hierarchical regression analysis and bootstrap methods, we find that person-job fit significantly enhances innovative behavior. Furthermore, self-efficacy and job involvement partially mediate this relationship. These findings offer practical implications for managers seeking to foster innovation by aligning employees’ roles with their skills and motivations, thereby improving organizational effectiveness and supporting strategic business decisions

Identification of the surface traces of historical earthquakes: one example from the southeast margin of the Tibetan Plateau

&amp;lt;p&amp;gt;The surface traces of historical earthquakes on the optical images are easily obscured by dense vegetation. Fortunately, the vegetation can be filtered and removed mostly or completely from LiDAR-derived cloud point data. We incorporate tectono-geomorphic interpretations of optical image, digital elevation model (DEM)-derived hillshades, contour maps, and field observations of tectono-geomorphic features and trenches to identify surface traces created by a historical earthquake. Based on DEM data, we used LaDiCaoz_v2_1 and 3D_Fault_Offsets to quantify offsets of tectonically displaced geomorphic markers. These approaches help us to recover an Mw7.5 historical earthquake at the southeast margin of the Tibetan Plateau, but the seismogenic fault had been considered as a weakly active fault and the magnitude of this earthquake was cited as M6.8 in the catalog of Chinese historic strong earthquakes from BC 2300 to AD 1911.&amp;lt;/p&amp;gt; </jats:p
