利益偿还请求权价值和性质探析

票据利益返还请求权作为票据法上一项特殊权利,在其性质方面争议颇多,我国学者普遍认为其是一种特别请求权。笔者认为特别请求权说并不能反映利益偿还请求权的本质,反而把该权利的性质变得更加深不可测。本文探讨了票据利益返还请求权的价值、性质,认为票据利益偿还请求权是一种不当得利请求权。

Earnings quality: Some evidence on the role of auditor tenure and auditors’ industry expertise

Prior studies suggest that auditors with short tenure are associated with lower earnings quality because of the lack of client-specific knowledge and/or low balling. In this study, we examine whether industry specialization of auditors and low balling affect the association between auditor tenure and earnings quality. We find that the association between shorter auditor tenure and lower earnings quality is weaker for firms audited by industry specialists compared to non-specialists. In addition, we do not find results consistent with the low balling explanation.

长江经济带生态环境保护与经济高质量发展的耦合协调关系及其影响因素

以长江经济带为研究地区构建生态环境保护与经济高质量评价指标体系。利用耦合协调模型、Dagum基尼系数、核密度和固定效应模型探究耦合协调度的时空特征、区域差异、动态演进特征及影响因素。结果表明：1）2008-2020年两系统发展指数均呈上升趋势。2）耦合协调度仍处于较低水平，具体表现为沿海下游省市>中心省市>上游省市。3）区域间差异是总体差异的主要来源，并且绝对差异缩小，梯度效应减弱。4）经济发展水平、人口聚集程度、产业结构升级和城镇化水平对耦合协调发展具有显著影响。     

Teacher qualifications and student achievement in urban elementary schools

Teacher quality is a key element of student academic success, but few specific teacher characteristics influence classroom outcomes. This research examines whether teacher licensure test scores and other teacher attributes affect elementary student achievement. The results are based on longitudinal student-level data from Los Angeles. California requires three types of teacher licensure tests as part of the teacher certification process; a general knowledge test, a subject area test (single subject for secondary teachers and multiple subject for elementary teachers), and a reading pedagogy test for elementary school teachers. The student achievement analysis uses a value-added approach that adjusts for both student and teacher fixed effects. The results show large differences in teacher quality across the school district, but measured teacher characteristics explain little of the difference. Teacher licensure test scores are unrelated to teacher success in the classroom. Similarly, student achievement is unaffected by whether classroom teachers have advanced degrees. Student achievement increases with teacher experience, but the linkage is weak and largely reflects poor outcomes for teachers during their first year or two in the classroom.
