高校知情权与学生隐私权的冲突与平衡     

徐爱萍  余淼  黄道主 《内蒙古师范大学学报(教育科学版)》2020,(2):16-20

充分了解学生是学校做好学生工作的重要前提。在学生管理实务中,高校知情权与学生隐私权之间的矛盾冲突主要表现为学生的个人信息被泄露、个人领域被入侵、私人活动被曝光等。其外因在于相关法律法规不完善,内因在于高校与学生间复杂的校生关系。因此,政府要进一步完善相关立法工作,高校要根据依法治校的要求科学管理,大学生要遵规守纪、合法维权。  相似文献

Multi-lagged-input iterative dynamic linearization based data-driven adaptive iterative learning control     

Na Lin  Ronghu Chi  Biao Huang  Zhongsheng Hou 《Journal of The Franklin Institute》2019,356(1):457-473

This article presents a multi-lagged-input based data-driven adaptive iterative learning control (M-DDAILC) method for nonlinear multiple-input-multiple-output (MIMO) systems by virtue of multi-lagged-input iterative dynamic linearization (IDL). The original nonlinear and non-affine MIMO system is equivalently transformed into a linear input-output incremental counterpart without loss of dynamics. The proposed learning law utilizes the desired trajectory to cancel the influence from iteration-by-iteration variations, as well as additional multi-lagged inputs to improve control performance. The developed iterative estimation law is more effective and also makes estimation of the unknown parameters easier because the dynamics for each parameter to represent are decreased by dividing the system into multiple components in the multi-lagged-input IDL formulation. Moreover, the proposed M-DDAILC does not need an explicit and accurate model. It is proved to be iteratively convergent with rigorous analysis. Both a numerical example and a practical application to a permanent magnet linear motor are provided to verify the validity and applicability of the proposed method.  相似文献

黄中俊 《体育科技文献通报》2020,(6):74-75,82

近几年来,我国网球运动蓬勃发展,前程似锦,但是世界级网球高手随处闪现,在技战术水平、心理素质等都优于同龄中国选手。不难发现,我国距离体育强调还有很长一段距离,只有大家齐心协力,共同努力,明确网球发展动向,才能实现体育大国向体育强国的跨越。因此,本文首先介绍新时期体育强国的要求,然后分析我国网球与世界网球强国的差距,最后研究体育强国视域下我国网球发展趋势。  相似文献   

Early Childhood Parenting Predicts Late Childhood Brain Functional Connectivity During Emotion Perception and Reward Processing     

Daniel C. Kopala-Sibley  Marilyn Cyr  Megan C. Finsaas  Jonathan Orawe  Anna Huang  Nim Tottenham  Daniel N. Klein 《Child development》2020,91(1):110-128

Seventy-nine 3-year olds and their mothers participated in a laboratory-based task to assess maternal hostility. Mothers also reported their behavioral regulation of their child. Seven years later, functional magnetic resonance imaging data were acquired while viewing emotional faces and completing a reward processing task. Maternal hostility predicted more negative amygdala connectivity during exposure to sad relative to neutral faces with frontal and parietal regions as well as more negative left ventral striatal connectivity during monetary gain relative to loss feedback with the right posterior orbital frontal cortex and right inferior frontal gyrus. In contrast, maternal regulation predicted enhanced cingulo-frontal connectivity during monetary gain relative to loss feedback. Results suggest parenting is associated with alterations in emotion and reward processing circuitry 7–8 years later.  相似文献   

The link between student-perceived teacher talk and student enjoyment,anxiety and discursive engagement in the classroom     

Gaowei Chen  Jiahong Zhang  Carol K. K. Chan  Sarah Michaels  Lauren B. Resnick  Xiaorui Huang 《British Educational Research Journal》2020,46(3):631-652

This study seeks to understand the emotional connection of teachers' academically productive talk (APT) with student learning from the students' perspective. Using a sample of 2,225 students (N_{7th grade} = 1,146 and N_{8th grade} = 1,079) from 16 middle schools in a city of China, we investigate the relationship between students' perceptions of their teachers’ APT, student emotions (enjoyment and anxiety) and their discursive engagement with others in the mathematics classroom. Results from structural equation modelling and mediation analysis show that after controlling for gender, family resources and mathematics achievement, student-perceived teacher APT was positively associated with their discursive engagement with classmates. Furthermore, student enjoyment and anxiety in class mediated the relationship between student-perceived teacher APT and student discursive engagement with classmates. Multi-group analysis revealed that the model was invariant across genders and grades, indicating that the associations were applicable to male and female students as well as to seventh and eighth graders. These findings shed light on the emotional relationship of teacher APT with the discursive engagement of their students. Although prior research observes a positive relationship between teacher productive classroom talk and student discursive engagement primarily through classroom observations and teacher reflections, this study provides evidence from the students’ perspective and highlights the mediating role of student emotions in the relationship.  相似文献
