区别性主从复合词的两种造词方式

在区别性主从复合词的造词活动中，主从复合词本身才是命名活动的目标，词根是参照，前加成分是为了使目标区别于参照而给目标添加的区别标识。前加成分可以分化词根，也可以异化词根。由异化方式或完全分化方式造成的几个词之间呈连续性，其系统比较稳定；由不完全分化造成的词呈离散性，其系统不稳定。分化与异化之间可以互相转化，条件是泛化或特化及有无标记对立的建立和失效。     

中国能源利用效率测度的国际对比研究

为解决国内日益尖锐的能源环境矛盾,应对国际气候变化的压力,中国能源利用效率的提高成为各方关注的焦点,而对其进行准确的统计测度和国际对比是必不可少的前提和基础。本文将能源消费者分为企业、政府和居民三大类别,从国家能源发展目标出发,构建测度指标体系,包括总分类指标、监控类指标、解释类指标和辅助说明类指标4 大类;在汇率法和购买力平价法核算方式下,采用熵权法与能源消费份额法确定各指标的权重,并与主成份投影法相结合,对中国、美国、日本等32 个国家和地区的能源利用效率进行测度分析,结果显示,在4 种组合条件下,我国能源利用效率的测度值分别为0.6207、0.5796、0.7854、0.7186,总体虽基本处于"较好"状态,但在32个样本国家和地区中排名分别为第26 位、第28 位、第8 位和第11 位,比较而言,购买力平价法下的测度值和排名更好,最后提出有针对性的政策建议。

Towards a model for research on the effects of school organizational health factors on primary school performance in Trinidad & Tobago

This article presents a model for research on the effects of school organizational heath factors on primary school academic achievement in Trinidad and Tobago. The model can be applicable for evaluating schools in other developing countries. As proposed, the model hypothesizes relationships between external factors (exogenous variables), school-level factors (endogenous variables), and school outcomes (student achievement and positive school climate). The endogenous variables are sub-scales of school organizational health. They include principal leadership, psycho-social environment, school–home–community relationships, teacher characteristics, curriculum quality, and school culture. These subscales are partially influenced by the Organizational Health Inventory OHI (Hoy and Feldman, 1987) and by school health indices set forth by the World Health Organization (1996). It is hoped that this school organizational health model can provide a conceptual tool for formulating a more comprehensive measure of healthy schools.     

Exploring principal capacity to lead reform of teaching and learning quality in Thailand

In 1999 Thailand passed an ambitious national educational law that paved the way for major reforms in teaching, learning and school management. Despite the ambitious vision of reform embedded in this law, recent studies suggest that implementation progress has been slow, uneven, and lacking deep penetration onto classrooms. Carried out ten years after the launch of the reform law, the current research sought to expand on these earlier studies by examining the capacity of Thailand's principals to lead reforms in teaching and learning. The study developed a national profile of principal instructional leadership using a Thai Form of the Principal Instructional Management Rating Scale ( Hallinger, 1994). The overall profile of 1195 primary and secondary school principals suggested a moderate level of engagement in two dimensions (Creating a School Mission and Developing a Positive School Learning Climate) and a lower level of activity on the dimension, Managing the Instructional Program. The results provide preliminary evidence which suggests that a more systematic human resource strategy is needed in order to ensure that Thailand's key school leaders have the knowledge, skills and motivation needed to support changes in teaching and learning envisioned in the nation's education reforms.     

高校教师职业压力问题研究综述

高校教师职业压力问题的研究已经引起了人们的高度关注。国内外学者认为高校教师职业压力主要来源于工作负荷过重、人际关系紧张、社会期望过高、政策调整过快和个人感受过强等方面。过大的职业压力会引起教师生理上、心理上、行为上的消极反应;容易导致教师职业倦怠和问题行为等。研究者大都主张在分析高校教师职业压力来源的基础上,采取应对性策略来缓解。     

On-site variety discrimination of tomato plant using visible-near infrared reflectance spectroscopy

The use of visible-near infrared (NIR) spectroscopy was explored as a tool to discriminate two new tomato plant varieties in China (Zheza205 and Zheza207).In this study,82 top-canopy leaves of Zheza205 and 86 top-canopy leaves of Zheza207 were measured in visible-NIR reflectance mode.Discriminant models were developed using principal component analysis (PCA),discriminant analysis (DA),and discriminant partial least squares (DPLS) regression methods.After outliers detection,the samples were randomly split into two sets,one used as a calibration set (n=82) and the remaining samples as a validation set (n=82).When predicting the variety of the samples in validation set,the classification correctness of the DPLS model after optimizing spectral pretreatment was up to 93%.The DPLS model with raw spectra after multiplicative scatter correction and Savitzky-Golay filter smoothing pretreatments had the best satisfactory calibration and prediction abilities (correlation coefficient of calibration (Rc)=0.920,root mean square errors of calibration=0.196,and root mean square errors of prediction=0.216).The results show that visible-NIR spectroscopy might be a suitable alternative tool to discriminate tomato plant varieties on-site.
