论过程的增值及对过程的测量

过程是应当增值的,而过场是不增值的。为了保证过程增值,需要按规定的程序来开展过程,需要对过程进行必要的测量,更需要对测量的结果进行监视和处置。同时,还要防止程序走过场,并淘汰不能增值的过程。

The Influences of Teacher Knowledge and Authentic Formative Assessment on Student Learning in Technology Education

Students involved in holistic technological practice need to develop an understanding of technological practice outside the classroom and to participate in tasks set as close as practicable to actual technological practice. This paper investigates the context of assessment and its relationship to achievement and the importance of teacher knowledge to student technological practice. I argue that ‘out of context’ assessment tasks do not give an accurate indication of achievement levels of the children assessed. Introduced is the Model of Student Technological Practice, which identifies four constraints that influence student technological practice. A significant factor is teacher knowledge, as it impacts greatly on the quality of feedback given to students by their teachers. Timely teacher intervention and formative assessment feedback will alter student technological practice and should improve the students’ likelihood of developing successful outcomes.

公允价值计量和金融资产减值相关理论研究

金融企业资产发生减值的情况已经大规模出现,由此产生的资产减值问题引起了人们的普遍关注。公允价值是会计发展的方向,新《企业会计准则》实现了与国际财务报告准则的趋同,其标志之一是公允价值的全面应用,这也意味着公允价值在我国面临的主要问题已经由“是否应当应用”转为“应当怎样应用、应当怎样更好的应用”。     

对ISO技术报告TR 24094的几点认识——兼论能量计量的不确定度评价

从天然气能量计量涉及的3种测量方法:流量测量、热量计测定发热量和气相色谱法测定组成,分别讨论了它们的溯源性;并指出对后2种测量方法我国目前尚未建立完善的溯源链,ISO标准体系中若干有关天然气分析的溯源准则及称量法制备标准气混合物的重要标准也尚未转化为我国国家标准。为了满足GB/T 18603中对A级站天然气能量计量的不确定度要求,对有关科研和标准化工作提出了若干建议。     

Product standards and developing country agricultural exports: The case of the European Union

This paper shows that voluntary product standards in EU food and agriculture markets can have significant trade effects. In particular for all countries and for goods that are raw or lightly processed, EU standards can often be trade-inhibiting. However, internationally harmonized EU standards—those that are equivalent to ISO norms—have much weaker trade effects, and in some cases are even trade-promoting. EU standards may have hurt developed countries more than developing countries, but this result is dependent on the sector. At a policy level, the results highlight the importance of dealing with the trade effects of voluntary standards in major markets, not just mandatory public standards.
