中原城市群的差异化经营策略探讨

城市群是关联紧密的城市空间,关系到国计民生大计。本文以中原城市群为例,立足于经营城市、差异化发展的理论基础,通过分析城市群的现状与发展条件,提出了城市群差异化经营的理念和发展策略。最后,探讨了中原城市群差异化发展的路径选择问题。     

Theoretical study of NO adsorbed on the surface of TiO<Subscript>2</Subscript> (110) cluster model

The chemisorption properties of N¹⁸O adsorption on TiO₂(110) surface were investigated by experimental and theoretical methods. The results of temperature programmed desorption (TPD) indicated that the temperatures of the three desorption peaks of the main N₂ molecules were at (low) temperature of 230 K, 450 K and (high) temperature of 980 K. This meant that N¹⁸O decomposed and recombined during the process of N₂ desorption after N¹⁸O was exposed. Analysis of the stable combination and orbital theory calculation of the surface reaction of NO adsorption on the TiO₂(110) cluster model showed that there was clear preference for the Ti-NO orientation.

安徽省物流发展能力综合评价

收集安徽省2012—2016年16个地级市与物流发展能力相关的时间序列数据,构建安徽省各地级市的物流发展能力评价指标体系,利用因子分析法和聚类分析法对安徽省各地级市的物流发展能力进行综合评价,分析影响物流发展能力的关键性因素。研究表明,安徽省区域的物流发展水平和发展能力存在明显的地域差异,其中,合肥市最强,阜阳市、芜湖市次之,池州市等城市最弱。应形成区域联动优势,以点带面;明确政府的主体责任,为物流发展保驾护航;打造规模化、品牌化、专业化、社会化的第三方物流企业,树立良好的物流企业形象。

Cluster analytic classification of reading disability subtypes

Cluster analysis was employed to identify subtypes of reading disability in a sample of 140 reading-disabled children using factor scores obtained from a battery of psychometric tests. Preliminary results suggested the existence of three subtypes, but closer scrutiny of the data indicated that individual differences are more accurately characterized by continuity in the measurement space. This result demonstrates the need for detailed validation of findings from applications of cluster analysis. Despite the absence of homogeneous subtypes, the characterization of individual strengths and weaknesses on psychometric measures may nonetheless be important for diagnosis and remediation in the educational setting.Behavioral Research Institute

What if reading is easy but unimportant? How students’ patterns of affirming and undermining motivation for reading information texts predict different reading outcomes

Many affirming and undermining motivational constructs affect students as they read information texts, but few researchers have explored how these motivations are patterned within students. In this study we used cluster analysis to classify middle school students (n = 1134) based on their patterns of self-efficacy, perceived difficulty, value, and devalue for reading school information texts. We then compared how the patterns predicted students’ language arts grades, science information text comprehension, and dedication to reading school information texts. We found and validated a four-cluster solution. One cluster included a pattern of high affirming and low undermining motivations, and another included low affirming and high undermining motivations. Students with these patterns earned the highest and lowest scores, respectively, on all outcomes. A third pattern showed high self-efficacy/low difficulty with low value/high devalue, and a fourth showed moderate levels of all four motivational constructs. Students with the high efficacy and devalue pattern showed high information text comprehension but relatively low dedication. Students with the moderate pattern showed high dedication but low initial information text comprehension. Students with these two patterns earned similar grades. We discuss the implications of our findings for motivation theories and for school instruction that involves information text reading.     

我国学术期刊集约化的发展脉络与对策研究

【目的】剖析我国学术期刊集约化的发展脉络与实践情况,并对遇到的问题进行思考,提出解决方案。【方法】 通过文献调研法收集期刊业界、学术界以及政策层面留下的文字记录,按时间脉络加以梳理,并参加期刊界相关的学术研讨会,通过与专业人士的交流,了解各事件发生的内在联系与实际情况。【结果】我国学术期刊的集约化过程是在理念借鉴、业界探索、政策支持、总结推广等多种因素的交错作用中发生的,虽然取得了一些初步成效,但由于行政主导的原因,仍然存在一系列不足。【结论】制约我国学术期刊集约化发展的一个主要原因是市场化不足,这需要进一步深化体制机制改革,给办刊主体更多的自主权,推动市场的多样化发展。
