论儿童阶段教师权威地位的重要性——对“师生平等”的反思

“平等”概念进入教育领域后，为我们解决了一些困扰已久的师生关系问题。但这种看似民主的师生平等观点，是否也夹杂着整个社会的权威退化值得探讨。在权威普遍丧失的今天，教育领域中万万不能丧失权威的概念，师生平等并不是师生关系最高标准，它甚至有弱化教师权威的倾向。如何建立起师生关系的最佳模式，如何帮助教师重塑在学生心目中应有的权威地位，阿伦特的权威观念也许可以作为一个指引。     

市场激励型环境规制对企业绿色技术创新的影响研究——以浙江省为例

随着我国经济的快速发展,环境污染问题日益突出。为解决环境污染和经济发展的矛盾,我国政府制定了环境税费、补贴、排污权交易及押金返还制度等市场激励型环境规制政策。当前,就环境规制是否会促进企业绿色技术创新,进而提高经济发展这一问题,国内外学者尚未达成共识。本文以市场激励型环境规制政策为研究对象,通过对浙江省污染行业企业的数据分析,并考虑市场激励型环境规制的强度,研究发现环境税费、环境规制强度对绿色产品创新有显著影响;环境税费、环境规制强度、排污权交易对绿色工艺创新有显著影响;排污权交易对绿色产品创新无显著影响;押金返还对绿色产品、工艺创新无显著影响。     

因材施教——声乐教学的重要法则

声乐与其它的艺术形式存在着明显的区别，由于难以形象地对声乐的乐理、思想等进行表达，因此在声乐教学的过程中如何有效地让学生更好地理解声乐知识，更好地掌握发声技巧等一直是广大声乐教师关注的重点。鉴于此，文章主要就声乐教学中的因材施教进行研究，通过努力在声乐教学中推动因材施教，学生才能对此会产生更浓厚的兴趣，更好地用声乐来表达内心的思想与情感。     

中国主要贵金属资源利用及关键性评估

贵金属资源同时具备工业属性和金融属性，不仅关系着国民经济的发展，更关系着国家的金融安全和国防安全。中国经济的发展带动了矿产资源需求的增加，对贵金属的需求量也是全球之最。本文参照欧盟的关键性矩阵研究，从经济重要性和供应风险两个维度，对金、银、铂、钯4种贵金属的供应风险开展研究，得到了中国贵金属的关键性矩阵，综合来看，4种贵金属的经济重要性由大到小的顺序为金>银>铂> 钯，供应风险由大到小的顺序为银>钯>铂>金。     

Robust influence diagnostics for generalized linear models with continuous responses

This article introduces two parametric robust diagnostic methods for detecting influential observations in the setting of generalized linear models with continuous responses. The legitimacy of the two proposed methods requires no knowledge of the true underlying distributions so long as their second moments exist. The performance of the two proposed influence diagnostic tools is investigated through limited simulation studies and the analyses of an illustration.     

Bayesian estimation of the stochastic volatility model with double exponential jumps

Review of Derivatives Research - This paper generalizes the stochastic volatility model to allow for the double exponential jumps. To derive the jumps and time-varying volatility in returns, we...     

Assessment of innovation and foreign direct investment: An investigation of OECD countries

Using a panel cointegration method incorporating structural breaks and cross-sectional dependence, this paper explores the long-run equilibrium relationship between innovation and foreign direct investment (FDI) in 30 OECD countries. The results from the panel stationary test show that FDI and innovation variables follow a stationary process with several structural breaks over the period 1999–2018. The results also suggest an equilibrium relationship with structural breaks between FDI and innovation in OECD countries. The panel dynamic OLS model with breaks further reveals that FDI is positively associated with innovation performance and vice versa in OECD countries. Therefore, this paper sheds light on the relationship between FDI and innovation in OECD countries.     

Total Factor Productivity and Energy Intensity: An Empirical Study of China’s Cement Industry

China is the largest cement producer and consumer in the world. The cement industry’s rapid growth has led to a large demand of energy. This study reviews China’s cement industry in terms of energy intensity and examines the effects of technological progress on energy intensity. It also discusses the feasibility of achieving China’s energy reduction targets. We employ the Granger causality test and find that the total factor productivity or technological progress causes the energy intensity of the cement industry. Impulse responses analysis also proves that in the long run the technological change contributes to the decline in energy intensity of cement production.

高校科研档案管理存在的问题及对策构想

科研档案管理工作是高校事业发展的重要组成部分之一,为了改善科研档案管理中存在的归档不及时、不完整、重档轻管、只存不用等问题,可以考虑采用分级管理模式、进行信息化建设、培训档案管理人员等方法来提升高校科研档案的质量和利用率。
