四川省FDI与环境污染问题初探

利用FDI在很大程度上促进了四川经济的增长。但与此同时,由于FDI直接涉及生产过程和资源利用,它对四川省环境也产生了不利影响。通过Granger因果关系检验发现FDI是四川省环境污染的Granger原因。实证分析结果表明,FDI和工业废气、废水排放物之间分别存在着协整关系,影响程度为实际使用FDI投资额每增加1％,工业废气、废水排放量均增加0．2％左右。

基于高光谱遥感特征参数的樟树幼林叶绿素a含量估算模型

以ASD公司生产的手持式野外光谱辐射仪测量樟树幼林的冠层光谱,同时对观测叶片进行叶绿素a含量的测定。利用统计相关分析法,分析了高光谱遥感特征参数与叶绿素a含量的相关关系,在此基础上建立了高光谱遥感特征参数的樟树幼林叶绿素a含量估算模型,并对模型进行了精度检验。结果表明:樟树幼林叶绿素a含量与Db、Rg、Rg/Ro、(Rg-Ro)/(Rg Ro)之间的相关系数达到了0.01极显著性检验水平;建立它们与叶绿素a含量的估算模型,通过精度检验,选择出最适合叶绿素a含量估算的高光谱模型:y=exp[1.027 (-348.942)×Db]。

Māori science education in Aotearoa New Zealand

Abstract    This article reports on the first two phases of a multiphase science education development project in predominantly Māori kura (school communities) in the central region of the North Island of Aotearoa New Zealand. The development project in its entirety employs an action research methodology and by so doing endeavors to support the improvement of science education delivery in accordance with school community aspirations. The full project (a) establishes the current situation in Year 1–8 science education in the communities; (b) identifies developmental aspirations for stakeholders within the communities and identifies potential contributors and constraints to these aspirations; (c) implements mechanisms for achieving identified aspirations; and finally; (d) evaluates the effectiveness of such mechanisms. In its focus on the first two phases, this article incorporates the analytical lenses of Kaupapa Māori Theory and Bronfenbrenner’s bio-ecological model. It concludes by outlining some priorities to consider for science education development based on the outcomes of our preliminary discussions.

Teachers’ perceptions of assessments of their mathematical knowledge in a professional development course

The purpose of the project reported in this article was to evaluate how assessing teachers’ mathematical knowledge within a professional development course impacted from the teachers’ perspective their learning and their experience with the course. The professional development course consisted of a 2-week summer institute and the content focus was geometry. We had decided to assess the mathematical learning of the teachers during this professional development course for various accountability reasons, but were concerned about possible negative by-products of this decision on the teachers and their participation. Thus, we worked to design assessment in ways that we hoped would minimize negative impacts and maintain a supportive learning environment. In addition, we undertook this evaluation to examine the impacts of the assessment, which included homework, quizzes, various projects, and an examination for program evaluation. Seventeen grade 5–9 teachers enrolled in the course participated in the study by completing written reflections and by describing their experiences in interviews. We learned that while our original intent was “to do no harm,” the teachers reported that their learning was enhanced by the assessment. The article concludes by describing the various properties of the assessments that the teachers identified as contributing to their learning of the geometry content, many of which align with current recommendations for assessing and evaluating grade K-16 mathematics students.
