  • 【期刊】 Assessment of Urban Human Settlements of Jinan City

    刊名:Applied Mechanics and Materials 作者:Luo ; Fang 关键词:Jinan City ; Principal Component Analysis (PCA) ; Urban Human Settlements 年份:2014
    摘要:Human Settlements are the basis of the human survival and development that the quality affects human health and is an important symbol to measure the progress of human society and cultural development. Based on the urban human settlements data of 2000-2009, evaluation system of urban human settlements of Jinan City was constructed from economic development, ecological environment and social culture in this paper which involved in per capita GDP, unemployment rate, the per capita areas of the urban roads, and the sewerage treatment rate etc.. Then urban human settlements of Jinan City were evaluated quantitatively by principal component analysis and the sort of synthetic quality was given: the urban human settlements of Jinan City are getting better and better notwithstanding fluctuations.

    摘要:

    The linear relations between math anxiety and math cognition have been frequently studied. However, the relations between anxiety and performance on complex cognitive tasks have been repeatedly demonstrated to follow a curvilinear fashion. In the current studies, we aimed to address the lack of attention given to the possibility of such complex interplay between emotion and cognition in the math-learning literature by exploring the relations among math anxiety, math motivation, and math cognition. In two samples—young adolescent twins and adult college students—results showed inverted-U relations between math anxiety and math performance in participants with high intrinsic math motivation and modest negative associations between math anxiety and math performance in participants with low intrinsic math motivation. However, this pattern was not observed in tasks assessing participants’ nonsymbolic and symbolic number-estimation ability. These findings may help advance the understanding of mathematics-learning processes and provide important insights for treatment programs that target improving mathematics-learning experiences and mathematical skills.

  • 【期刊】 Roof Runoff Replenishment of Groundwater in Jinan, China

    摘要:In Jinan, China, which is named the Spring City of China, karst groundwater is an important water source for urban supply and maintaining spring flow. However, rapid urbanization in Jinan, China, has caused overexploitation of groundwater and an increase in surface runoff. Consequently, roof runoff harvesting and recycling via the aquifer is being considered to augment the recharge for this area. A pilot-managed aquifer recharge scheme with urban roof runoff was investigated as part of this case study to supplement groundwater recharge. This case study is intended as a pilot for the wider application of managed aquifer recharge at the University of Jinan. The pilot-scale system is composed of the roof catchment, first-flush removal device, regulating tank, filter tank, and recharge well; dimensions and operating parameters of each component were designed by laboratory experiment and hydraulic calculations. The quality of roof runoff is better than road runoff; however, it is still contains a number of hazards. The injected water quality must meet the quality standard for groundwater for the protection of potable groundwater quality. Barriers, or measures to protect water quality, within the treatment train include first-flush removal (first 6 mm rainfall) followed by sedimentation and filtration in a zeolite filter. Water quality monitoring of each barrier and geochemical simulation were used to evaluate the potential influences on groundwater recharge and quality. The rainfall, recharge quantities, and groundwater levels as well as water quality through the recharge process were monitored continuously in June to November 2012. All indexes of treated roof runoff were below the quality standard for groundwater, with the exception of turbidity. Geochemical modeling indicates there is some calcite dissolution after injection but this does not pose a risk to the operational lifetime of the recharge well. However, pretreatment of the source water still needs further improvement to decrease the turbidity to acceptable levels. In addition, water quality risk management is also required for sustainable long-term operation of the scheme. (C) 2014 American Society of Civil Engineers.
  • 【期刊】 Cross-sectional epidemiological survey of asthma in Jinan, China

  • 【期刊】 Framework of Integrated Stormwater Management of Jinan City, China

    刊名:Procedia Environmental Sciences 作者:Ranran Yang ; Baoshan Cui 关键词:water resources; integrated stormwater management 年份:2012
    摘要:The fast pace of urbanization puts stress on water resources. There are water shortages in many big cities. At the same time, the increase of impermeable surfaces makes floods more frequent. The conflict of water shortages and flood risk indicates that traditional stormwater management should be changed. Traditional stormwater management routes runoff directly to streams and rivers, exacerbating pollutant inputs and hydrologic disturbances that result in the degradation of ecosystem structure and function. The new stormwater management techniques integrate stormwater collection, treatment, storage and reuse. Integrated management could be implemented on the roads, parking lots, depressed grassland and building roofs. This will reduce the runoff volume released by floods downstream, thereby reducing pollution and improving aquatic function. However, the integrated approach is just starting in many Chinese cities and there are lots of things to do.

  • 【期刊】 Early math interest and the development of math skills.

    刊名:Journal of Educational Psychology 作者:Fisher, Paige H. ; Dobbs-Oates, Jennifer ; Doctoroff, Greta L. ; Arnold, David H. 关键词:math ; interest ; achievement ; preschool 年份:2012
    摘要:Prior models suggest that math attitudes and ability might strengthen each other over time in a reciprocal fashion (Ma, 1997). The current study investigated the relationship between math interest and skill both concurrently and over time in a preschool sample. Analyses of concurrent relationships indicated that high levels of interest were related to strong math skills. Even when controlling for initial interest and a brief intelligence measure, math skills predicted math interest approximately 5 months later; in the same way, early interest predicted later skill, even controlling for initial interest. These findings suggest that a reciprocal relationship between math interest and math ability may be in place as early as preschool.
