Half-precessional cycle revealed by environment magnetism of stalagmite in Shizhu Cave from southwestern china during the Last Glacial

The environmental magnetic proxies of stalagmites hold significant potential for reconstructing regional hydroclimate changes by revealing the content and grain size of magnetic particles within stalagmites. In this study， we present the contents and grain sizes of magnetic particles within a stalagmite SZ-1， from Shizhu Cave in southwestern china from 70.4 to 22.3 thousand years ago (ka) during the last glacial period. Specifically， the parameters IRMsoft， soil-derived magnetic minerals， and ARM/SIRM (anhysteretic remanent magnetization/saturation isothermal remanent magnetization)， the ratio of fine magnetic particles to total ferrimagnetic particles preserved in stalagmite SZ-1， indicate the fluctuation of regional precipitation. Obvious half-precessional cycles are evident in these two proxies， indicating that hydroclimatic variations in southwestern china may predominantly arise from the heat and moisture transported from tropical oceans. These variations are likely influenced by shifts in the Intertropical Convergence Zone and fluctuations in the Asian summer monsoon.

This paper explores the narratives of the chinese woman novelist Shao-Lin Chu’s trilogy to see how the problem of female sexuality and resistance to parental wedlock tragedy becomes a traumatic *** traumatic symptoms in the narratives are taken as Peircean signs for tracing the negative influences of traumatic experiences on the formation of personal identity and the associated depressive *** scenes portrayed in Chu’s traumatic narratives of female and male sexuality are implications and representations of how sexuality is conceptualized and confined by the traumatic events while backgrounded with regulations and restrictions of a traditional *** stories of Chu’s female narrators reveal the persistent and resisting feminine *** paper adopts the concept of feminist narrative to analyze the traumatic and sexual events in Chu’s *** decoding and re-encoding of resistance and sexuality in the traumatic narratives prove that the narratological textual analysis and semiotic reading strategy together offer a solid approach to the discovery of the persistent traumatic impacts of the secret veiled in the narratives and reveal the probable strength of compassion that has its roots derived from deplorable trauma but later transforms itself to stimulate a positive reconstruction of the traumatic survivors’identity.
