考虑偏差路径的电动汽车充电站选址和定容

为在电动汽车推广初期提升其在物流配送领域的接受度,缓解途中驾驶人员的"里程焦虑",对电动汽车充电站的选址和定容进行合理规划。不仅考虑驾驶人员为给电动汽车充电而愿意偏离最短路径行驶的偏差路径,还考虑电动汽车进入充电站后的等待时间,提出一个双目标混合整数规划模型。以偏差路径中的车流量来模拟充电需求,以最大化满足路径中需求与最小化平均等待时间两个目标之间的相互平衡作为衡量选址和定容合理性的指标,从而得到充电站的合理规划。结果表明:单次充电行驶里程、偏差距离和服务速率对充电站的选址和定容有重要影响。     

Banach空间中一类广义混合平衡问题系统解的存在性及算法

在实Banach空间中引入和研究了一类新的广义混合平衡问题组.首先考虑了一个辅助混合平衡问题组,通过它与广义混合平衡问题组的等价性,证明了它的解的存在性和唯一性;其次构造了广义混合平衡问题组的近似解的迭代算法.在一定的条件下,证明了由算法生成的迭代序列的强收敛性,这些结果推广并改进了近期的某些结果.     

Comparative School Marks of September and January Junior High-School Entrants

ABSTRACT

The author used an explanatory mixed methods research design. The first phase involved the collection of quantitative data to examine the nature of preservice teachers’ (N = 192) culturally responsive teaching self-efficacy beliefs. Follow-up face-to-face interviews were carried out with a subsample selected from Phase 1 participants. These interviews were used to identify the types of culturally responsive teaching self-efficacy-forming experiences that preservice teachers encountered during their teacher education program and the perceived influence that these experiences had on the development of their self-efficacy beliefs. The face-to-face interviews uncovered disparities among preservice teachers regarding the aspects of culturally responsive teaching that were discussed, modeled, and practiced. The theoretical and practical implications of this study are discussed.     

Exploring Top Hat’s Impact on Undergraduate Students’ Belongingness,Engagement, and Self-Confidence: A Mixed Methods Study

Abstract

Evidence suggests that the use of educational technologies may promote positive learning environments and contribute to students’ success. The following mixed methods study examined the impact of Top Hat in a blended learning environment on undergraduate students’ sense of belongingness, engagement, and self-confidence in a Canadian post-secondary institution. A survey study measured students’ sense of belongingness, engagement, and self-confidence before and after the course, which used Top Hat. The results show a significant increase in belongingness and self-confidence, but a decrease in engagement. Contrarily, focus groups revealed that using Top Hat may improve the overall learning experience. Limitations and future recommendations are discussed.     

现代国家金融业监管模式剖析

本文所称金融业监管有利于商业银行等金融企业的内部风险管理，是政府或行业自律组织对它的外部监管。银监会的成立有利于实行更好地集中共货币手段，而不为监管所累，也有利于监管的高效，但在银监会之后应尽快出台一个跨机构监管协调委员会。
