关于我国现行《保险法》中受益人问题的法律思考

在人身保险合同中,受益人是保险合同利益的最终受益人,在理论和实践中占据重要地位。关于受益人的概念、受益人的资格、受益人的指定和变更、受益人受益权的丧失等问题在我国现行《保险法》中的规定虽然对以前的《保险法》进行了修改,但是仍有一些让人不易理解之处,将针对这些问题进行一些法律思考,旨在减少相关法律纠纷。

Ethical and political dimensions of action research and lesson study: reflections from a research project on a controversial issue in Cyprus

ABSTRACT

As educational interventions that integrate death issues in the school curriculum are rarely designed, implemented and evaluated, our action research (AR) project aimed at investigating the complexities of integrating the concepts of loss and grief in the primary school curriculum of Cyprus. The purpose of this paper is to identify and analyze convergences and divergences between AR and lesson study (LS), as they emerged in our project. We particularly focus on the ways that AR served to legitimate ethically and politically those aspects of the project that constituted the experimentation of lesson plans on loss and grief. The AR and LS elements of our project functioned differently and served different purposes, and we speculate that this is not irrelevant to the controversial aspects of the lesson plans’ topic, namely loss and grief. The paper argues that it may be strategically important, for ethical and political reasons, to both demarcate and associate AR and LS, navigating between them, particularly if a controversial issue is involved.     

Difference score reliabilities within the RIAS-2 and WISC-V

Many prominent intelligence tests (e.g., Wechsler Intelligence Scale for Children, Fifth Edition [WISC-V] and Reynolds Intellectual Abilities Scale, Second Edition [RIAS-2]) offer methods for computing subtest- and composite-level difference scores. This study uses data provided in the technical manual of the WISC-V and RIAS-2 to calculate reliability coefficients for difference scores. Subtest-level difference score reliabilities range from 0.59 to 0.99 for the RIAS-2 and from 0.53 to 0.87 for the WISC-V. Composite-level difference score reliabilities generally range from 0.23 to 0.95 for the RIAS-2 and from 0.36 to 0.87 for the WISC-V. Emphasis is placed on comparisons recommended by test publishers and a discussion of minimum requirements for interpretation of differences scores is provided.     

Is academic tracking related to gains in learning competence? Using propensity score matching and differential item change functioning analysis for better understanding of tracking implications

This study analyzes gains in cognitive components of learning competence with respect to cohorts based on ability tracking in a Czech longitudinal study. Propensity score matching is used to form parallelized samples of academic and non-academic track students and to eliminate the effect of selective school intake. We applied regression models on the total scores to test for the overall track effect. Furthermore, we analyze scores and gains on the subscores and check for differential item functioning in Grade 6 and in change to Grade 9. While after 3 years, no significant difference between the two tracks was apparent in the total learning competence score, we did, however, find significant differences in some subscores and in the functioning of some items. We argue that item-level analysis is important for deeper understanding of the tracking implications and may provide the basis for more precise evidence-based decisions regarding the tracking policy.     

串行同步双缓冲扫描提高平板显示器的显示亮度和传送利用率

This paper presents a serial synchronous scanning mode in flat panel display (FPD) by adding a latch buffer between the serializer and the driving buffer. Comparing with conventional techniques, the proposed structure can efficiently reduce the brightness loss and improve the transmission performance. Theoretical analysis and experimental results show that the ratio between the lightest weight display time and the relative transmission time is a tradeoff between brightness loss and transmission efficiency.     

高校文科学报人文性缺失之我见

高校文科学报在充分体现学术性、具有独特性的同时，还必须注重体现人文性，这不仅是其自身生存与可持续发展应有之意。也是构建和谐社会的需要。高校文科学报要努力做到：发挥传承老一代学人的优良学术传统和注意奖掖新人的作用；拆除学术壁垒，大力弘扬主流文化，同时包容无害于社会发展的非主流文化；跨越校际与地域的界限。努力去承载学科研究的最高成果；在编辑、排版、设计等方面折射出编辑的人文主义理念。
