Analysis of Childhood Sexual Abuse among 1099 University Students in Shanghai

Journal of Reproduction and Contraception 2010年第1期21卷 53-61页

作者： hong-feng niu Chao-hua LOU Er-sheng GAO Xia-yun ZUO Iqbal Shah Shanghai Institute of Planned Parenthood Research Shanghai 200032 China Department of Reproductive of Health and Research World Health Organization

Objective To understand the situations of childhood sexual abuse （CSA） and to examine associations of CSA with demographic factors and with later risk behaviors among university students in Shanghai, China. Methods A two-stage random sampling method was adopted to conduct the survey anomalously using electronic questionnaire and computer-assisted-structured-interview method. Results About 15.1% （10.2% among male, 18.2% among female） university students reported having had experienced CSA before age 14, 1.2% university students reported having had experienced abuse of attempted vaginal or anal intercourse and 0.8% university students experienced abuse of forced vaginal or anal intercourse. The perpetrators were mainly strangers （accounting for 40.3%） and classmates or friends of the victims （23.9%）. Family members or relatives accounted for 11.3% of the perpetrators. Female students who came from cities （21.9%） reported more CSA experiences than those who came from townships （10.1%） or rural areas （8.2%）. Association between CSA experiences of victims and their parents education levels was not found. Those respondents who had ever experienced CSA before age 14 had reported more later risk behaviors than those who had not experienced CSA： males with CSA reported more experiences of ever fighting and more often involved in forced sexual intercourse than those without CSA, while females with CSA reported more experiences of smoking, running away from home, ever fighting, watching pornography and more unmarried sexual intercourse than those without CSA. Conclusion CSA is not rare among university students and associated with later risk sexual behaviors. It is important and urgent to pay attention to the issue of CSA and take prevention measures to protect children.

目的:探讨大学生中儿童期性虐待的发生状况,为保障儿童免受性虐待制定预防对策提供参考依据。方法:使用电子问卷在上海市4所大学对1099名大学生开展儿童期性虐待经历情况的匿名调查。结果:15.1%(男生10.2%、女生18.2%)的大学生在14岁前至少经历过1种或几种不同形式的身体接触或非身体接触的性虐待,1.2%的人曾被试图性交或肛交,0.8%的人曾被强行性交或肛交。施虐者主要是陌生人(40.3%)和同学/朋友(23.9%),还有11.3%为家庭成员或亲戚。来自城市的女大学生比来自城镇和农村者遭受儿童期性虐待的比例更高。未显示父母的文化程度与儿童期性虐待的发生有关联。经历过儿童期性虐待的对象以后发生性行为和强迫性行为的危险更高。结论:在大学生中儿童期性虐待问题较常见,且与以后的高危性行为相关,应加强对这一问题的关注并采取相应的预防措施。

Dynamically self-adjustable liquid-liquid and self-adaptive softcontact solid-solid triboelectric nanogenerator for wave energy harvesting

引用

Nano Research 2025年第1期18卷 404-414页

作者： Yong Long Bingqi Zhao Jianan niu Yuxiu Liu Wei Sha Jiangwen Wang Zhong Lin Wang Weiguo Hu Guangzhou Institute of Blue Energy Knowledge CityHuangpu DistrictGuangzhou 510555China Beijing Institute of Nanoenergy and Nanosystems Chinese Academy of SciencesBeijing 101400China School of Nanoscience and Technology University of Chinese Academy of SciencesBeijing 100049China

Water wave energy exhibits great potential toalleviate the global energy crisis. However, harvesting andutilizing wave energy are challenging due to its irregularity,randomness, and low frequency. Triboelectric nanogenerators(TENGs) have gained significant attention for harvesting waveenergy with high efficiency. This study presents a novelellipsoidal, pendulum-like TENG integrating both liquid-liquid(L-L) and solid-solid (S-S) triboelectricity (LS-TENG). Thisinnovative design enables continuous wave energy harvestingand self-powered marine environment monitoring under variousconditions, including temperature, humidity, and light intensity. The binary immiscible liquids within the LS-TENG’s innersoft balloon create dynamic, and self-adjustable L-L contact interfaces, significantly increasing the L-L contact area andenhancing L-L contact electrification (CE). The unique self-adaptive, soft S-S contact increases the S-S contact areacompared to traditional hard point contact, better adapting to the irregular movements of waves and promoting efficient S-SCE. The LS-TENG achieves highly efficient wave energy harvesting by coupling L-L and S-S CE. Furthermore, the uniquesoft contact design protects the S-S interfaces from mechanical wear and damage during long-term work. The LS-TENG’snovel structure provides an innovative and effective way for water wave energy harvesting.

Microstructural Evolutions and Mechanical Properties of Energetic Al_(1) (TiZrNbTaMoCr)_(15) High-Entropy Alloys

引用

Acta Metallurgica Sinica(English Letters) 2024年第4期37卷 620-632页

作者： Xuan-hong Cai Zhen-Hua Wang Ben niu Jin-feng Li Qing Wang Show authors Key Laboratory of Materials Modification By Laser Ion and Electron Beams(Ministry of Education)Engineering Research Center of High Entropy Alloy Materials(Liaoning Province)School of Materials Science and EngineeringDalian University of TechnologyDalian116024China Institute of Materials China Academy of Engineering PhysicsMianyang621908China

The present study focuses on investigating the microstructural evolutions and mechanical properties of energetic Al_(1)(TiZrNbTaMoCr)_(15) refractory high-entropy alloys with the different heat treatments at low Al content state. It is found that even with a reduction in the Al content, the strength of these alloys remains unaffected at room temperature and high temperature, while the plasticity improves significantly. In particular, the coherent BCC/B_(2) microstructure with needle-like B_(2) nanoprecipitates dispersed into the BCC matrix is formed in 873 K-aged Al_(1)Ti_(6)Zr_(2)Nb_(3)Ta_(3)Mo_(0.5)Cr_(0.5) alloy. Therefore, this alloy exhibits the highest compression yield strength (σ_(YS) = 1333 and 717 MPa) at room temperature and 1073 K, respectively. After 973 K-aged, the coherent BCC/B_(2) microstructure underwent destabilization, and the B_(2) phase transforms into the brittle Zr5Al3 phase which then coarsens and dominates the microstructure of S3-AlTa_(3) alloy after 1073 K-aged. Moreover, these current alloys exhibit exceptionally high theoretical exothermic enthalpy (ΔH), surpassing 11606 J·g^(−1), which highlights their significant potential as innovative high-performance energetic structural materials.
