我省专科学生使用互联网存在的问题及对策

高职高专学生在我省大学生群体占有较大的比重。他们对互联网的认识和使用中 存在一些带有普遍性问题。针对这些问题。我们提出了一些教育对策和建议。     

A strategic design approach to develop sustainable product service systems: examples taken from the ‘environmentally friendly innovation’ Italian prize

The product service systems’ (PSS) sustainability potential is described in the framework of the new types of stakeholder relationships and/or partnerships, producing new convergence of economic interests, and a potential concomitant systemic resources optimization.In this perspective, it is argued that the design competencies should move towards those of the ‘strategic design’, thus introducing the concept of ‘strategic design for sustainability’: the design of an innovation strategy, shifting the business focus from designing (and selling) physical products only, to designing (and selling) a system of products and services which are jointly capable of fulfilling specific client demands, while re-orienting current unsustainable trends in production and consumption practices.Some examples of PSS are presented and discussed using the PSS categories ‘services providing added value to the product life cycle’, ‘services providing final results to customers’, and ‘services providing enabling platforms for customers’. The cases derive from an analysis of the ‘environmental friendly innovation’ yearly endowed prize submissions. The Politecnico di Milano University together with the Bocconi University and Legambiente (an environmental NGO) promotes the initiative in Italy.

“互动式”教学方法在中小学环境教育中的应用

介绍了“互动式”教学方法的特点及其实施计划．通过编写中小学“互动式”环境教育系列教材，培养环保部门教育官员、中小学教师、师范院校师生以及建立教师资源库，从而逐渐把“互动式”教学方法推广到全国中小学环境教育教学计划中．     

铁路专用线声环境影响评价

针对新建铁路专用线沿线的环境特征，提出了铁路专用线声环境影响评价的程序、内容和方法。在目前缺乏新建铁路噪声预测模式的情况下，提出了应对铁路边界噪声、不同距离处的铁路噪声、敏感点噪声、鸣笛噪声进行预测，并以某铁路专用线声环境影响评价为例，对上述四种噪声进行了预测，通过预测得到铁路两侧的声环境状况，并以此为依据提出了铁路噪声的防治对策，以保证铁路专用线沿线声环境质量。     

如何培养学生学习数学的兴趣

学习兴趣在学生的学习中占有重要地位。为了培养学生学习数学的兴趣,教师应充分利用数学的学科特点,合理安排教学内容,灵活运用教学方法,并在学生遇到困难时给予及时的帮助。     

谈孔子的德育方法

孔子的德育方法可分为教育者教的方法和受教育者自我教育的方法。对于教育者来说，要做到：诲人不倦；“正人”必先“正己”；因材施教；寓德育于智育之中。对于受教育者来说，要做到：学为人之道；克己内省；就有道而正焉；从孝悌做起；践履躬行。文章最后提出，对孔子的德育方法的正确态度是结合时代要求批判继承。

Connecting sources, fractions and algal availability of sediment phosphorus in shallow lakes: An approach to the criteria for sediment phosphorus concentrations

Although point and nonpoint sources contribute roughly equal nutrient loads to lakes, their relative role in supporting algae growth has not been clarified. In this research, we have established a quantitative relationship between algae-available phosphorus (P) and P chemical fractions in sediments; the latter indicates the relative contribution of point versus nonpoint sources. Surface sediments from three large shallow lakes in eastern China, namely, the Chaohu, Taihu and Hongzehu Lakes, were sampled to assess their algae-available P and chemically extracted P fractions. The algae-available P primarily comes from iron/aluminium (hydr)oxide-bound P (Fe/Al-bound P), 45% of which is algae-available P. The ratio of Fe/Al-bound P to calcium compound-bound P (Ca-bound P) indicated the relative contribution of point to nonpoint sources, with the point sources contributing the majority of increased Fe/Al-bound P in sediments. Therefore, the reduction of point sources from urbanized areas, rather than nonpoint sources from agricultural areas that primarily contribute to the Ca-bound P fraction, should be prioritized to alleviate cyanobacterial algal blooms (CyanoHABs) in shallow lakes with sediment P as a potential source to support algae growth. With these important results, we proposed a conceptual model for “P-pumping suction” from sediments to algae to aid in the development of the criteria for sediment P concentrations in shallow lakes.
