As one of the most important participants in construction industry, construction workers' unsafe behavior is very common on construction sites. From an individual level, this research aims to investigate the relationship among risk perception, risk propensity and unsafe behavior decision-making. A survey is conducted within first-line workers in Chinese construction projects. The results show that:...
There are many similarities on fluctuations between clothing styles and finance so that many theorists approach to analyze the relationship of them, the best known of which is the Hemline Index Theory. When the economy is flourishing, hemlines increase, and when the economic situation is deteriorating, the hemlines drop, perhaps even to the floor. In contrast with measuring the illustrations from...
In this study, we present a detailed inter-annual analysis of four remotely sensed leaf area index (LAI) products: GLASS, GLOBALBNU, GLOBMAP, and MODIS LAI, and conduct correlation analysis between LAI and three meteorological variables over China. The results manifest that the four products agree well in most of northern regions of China, with higher correlation coefficient and the same response...
Atmospheric particulate matter estimated by using satellite data is gaining more attention due to their wide spatial coverage advantages. Here, instead of empirical statistical approach, we describe a physical-based approach that reduces the uncertainty of surface PM10 estimation from satellite data. In our approach, particulate matter mass concentration retrievals require the inclusion of optical...
In this paper, an evaluation index system of science and technology (S&T) innovative capacity is designed, using the AHP method for weight assignment. The raw data of these third-order indexes is obtained from “Compilation of Science and Technology Statistical Information in Colleges and Universities”. Taking 31 provinces as samples, an evaluation on S&T innovative capacity of universities...
This research adopts empirical approach to investigate structure features of employees' silence in interests' expressions (ESIE) and its coping styles. The result shows that in organizations, the interests of employees are related to four aspects: survival, development, relationship, and the interest of value inclination; the ESIE mainly are negative cognition; the ESIE includes: cognitive silence,...
Based on the basic data of the housing price and housing price-to-income ratio in 286 prefecture-level cities in 2009, this paper analyzes the spatial differentiation pattern, overall trend, spatial heterogeneity and correlation between the absolute housing price and relative housing price. The results show that: 1) there is significant spatial differentiation in terms of China's urban housing price,...
Eco-innovation (EI) pursues to bring environmental and economic win-win outcomes, including competitive performance and environmental performance, which possess the property of double externality and to present multi-motivations. Based on empirical analyses of EI on 246 enterprises in China, the econometric estimations show that the impact of different motivations on EI performance. In this study,...
The logistics industry has played a more and more important role in the modern economic development. This paper analyzed the input-output relation on modern logistics industry and the other industries with Chinese input and output data, and calculated the effect coefficient, sensitivity of dispersion coefficient, production spread effect and price spread effect of logistics industry to the other industries...
In order to make a quantitative analysis on spatial pattern of headquarters about top 500 enterprises of Chinese service industries, the software of ArcGIS 9.2 was adopted. The results showed that the headquarters were mainly distributed in the eastern coast region of China. The value of global Moran's I was about 0.11. High value regions were all distributed in the eastern coast region of China and...
Geographers, demographers and other scholars have a sustaining interest in China's population distribution. The research is based on China's GIS data sets of population census in 1953, 1964, 1982, 1990 and 2000. The first part of this study is to analyze the population density patterns by various spatial analysis methods and explain possible influencing factors. The second part analyzes population...
With the rapid growth and development of China's economy, the hotel industry has correspondingly experienced extraordinary growth demonstrating different interesting characteristics of its spatial distribution geographically. The paper seeks to analyze these spatial characteristics affecting the dynamic system of tourism development based on the six dynamic indicator covering twelve influential factors...
Although some documents deal with the impacts of producer services on regional innovation capability, relative empirical studies are rarely found in China. The relationship between producer services and innovation capability of state-level hi-tech development zones is empirically studied with principal component analysis and correlation analysis respectively, and it is proved that producer services...
Begin with theory summary of economic development pattern, the paper forecasted GDP per capita in 2020 as indicator of economic development in China based on the optimization of gray model with logarithm new developments coefficients, analyzed influence of population structure on economic development by gray correlation model. The conclusion shows that population industry structure, urban and rural...
This paper reports an investigation into the urban expansion in Beijing during 2004-2009 and its impact on land surface temperature (LST), as well as the relationship between LST and NDVI. LST and landuse/land-cover (LULC) data were extracted from Landsat Thematic Mapper (TM) images acquired on September 8, 2004 and September 22, 2009. The spatial pattern of LST before and after the 2008 Summer Olympic...
In order to investigate the fruit quality of tomato (Lycopersicon esculentum mill) affected by microenvironment and soil water and fertilizer, the field experiment was conducted in a greenhouse in Ansia research Station of Soil and Water Conservation, Chinese Academy of Science, Yan'an, Shaanxi province, China, from March to October in 2008 and 2009. The research results showed that soluble protein...
Based on the observation of the thunderstorm days at ten weather stations in the area of Linyi, the characteristics of temporal and spatial distribution of thunderstorm days from 1962 to 2009 has been analyzed. The results indicate that the thunderstorm days are varied in different regions of the area, but the differences are small. The thunderstorm days decreased significantly by 3.4 days for every...
Based on 1961-2008 day-by-day meteorological data observed by Linyi stations, using correlation analysis and wavelet analysis method, the correlation and tendency of the pan evaporation and the main influence factors (sunshine, temperature, daily temperature range, relative humidity and wind speed, etc.) of the recent 48 years are researched. The results show that, in recent 48 years, the average...
The paper presents the principle and calculation process of the principal component analysis which is a useful method of water quality assessment. Eight indicators include dissolved oxygen, permanganate index, BOD, ammonia nitrogen, copper, zinc, volatile phenol, oil in 20 monitoring sections of Ningbo urban river were analyzed by using principal component analysis. Three factors with 86.67% of accumulated...
The Zhuhai city in Pearl River Delta was chosen as a study area. The soil samples were recollected according to the sampling points of Second National Soil Survey. Based on application of geographical information system (GIS) and SPSS software, the content, distribution and its influence factors of available Cu in cultivated soils were analyzed. The results showed that: the average available copper...
