Comparison of Cancer Incidence between China and the USA

Objective The incidence of cancer varies around the globe,especially between less-developed and developed regions.The aim of this study is to explore differences in cancer incidence between China and the USA. Methods Data were obtained from the GLOBOCAN 2008 database.Estimated numbers of new cancer cases in the USA were obtained from the American Cancer Society,while the numbers of cases in China,including those in urban and rural areas,were obtained from 36 cancer registries(2003-2005).Cancer incidence for major sites between China and the USA were analyzed. Results In China,lung cancer was the predominant type of cancer detected in males;in females,breast cancer was the main type of cancer.Gastrointestinal cancers,such as those of the liver,stomach,and esophagus,were more commonly seen in China than in the USA.A significant difference in the incidence of melanoma of the skin was observed between China and the USA.During comparison of differences in the age-standardized rates by world population(ASRWs) of major cancer sites between the two countries,4 sites in males(i.e.,nasopharynx,esophagus,stomach,and liver) and 6 sites in females(i.e.,nasopharynx,esophagus,stomach,liver, gallbladder,and cervix uteri) showed higher cancer incidence rates in China than in the USA. Conclusions Significant differences in cancer incidence sites were found between the two countries.Cancer may be prevented through public education and awareness.Programs to promote cancer prevention in China,especially those of the lung,breast,and gastrointestinal region,must also be implemented.

Changes in Spatiotemporal Land Use Patterns in Selected Hydrogeomorphic Areas of China and the USA

Differences exist in land use/cover pattern and its change between the P. R. China and the USA. In order to describe those differences, land use changes in representative regions were quantitatively analyzed and compared. Xiamen City, Changzhutan region and Liupan Mountains regions were selected to represent three different hydrogeomorphic areas of eastern, central, and western China, respectively, while the Goodwin Creek Experimental Watershed (GCEW) located in the north-central part of Mississippi in the bluff hills just east of the Mississippi River floodplain was chosen in the USA. By integrating historical Landsat TM imagery and geographical information system data, the spatiotemporal land use dynamics and conversion of land use in China and the USA between 1980 and 2010 were explored and compared. Results indicated an urban sprawl in eastern and central China, which encroached upon large amount of cropland, forest land and grassland. On the other hand, western China reclaimed cropland from grassland, forest land, which led to severe soil erosion between 1990 and 2000. Goodwin Creek Watershed of the USA converted 73.3% of the lost cropland into forest land, pasture and idle land, which accounted for about 90% in 2010. Further, counter-urbanization occurs in the GCEW due to favorable eco-environment for living. Compared with the land dynamic degree of the GCEW, eastern China is greater than it;western China is smaller than it while central China is almost equal to it. And the land use intensity index of GCEW is smaller than that of China all these years. Eastern China advocated ecological civilization in 2007 to meet the serious challenges of sustainable development. Western China started the Return of Land from Farming to Forestry and Grassland Project in 2000. The Changzhutan region in central China is served as the resource-saving and environment-friendly community in 2007, which will be favorable for the sustainable land utilization and protection of ecology. From the eco-environmental view, China might use the experience of USA for future reference.

A comparison and interpretation of the international competitiveness of China and India

This paper first presents a comparison between China and India with respect to their overall economic and social development conditions and finds that China is currently at a higher development stage than India in terms of key economic indicators or social indicators.This paper also conducts an assessment of the international competitiveness of the Chinese and Indian manufacturing industries and finds that the Chinese manufacturing industry is more competitive than its Indian counterpart.This paper then conducts an evaluation of the international competitiveness of the Chinese and Indian service industries and finds that(1)the Indian service industry has remained more globally competitive than its Chinese counterpart in most of the years examined;(2)the Chinese service industry has derived its international competitiveness primarily from its competitive advantages.In spite of its weaker comprehensive competitiveness,the Chinese services industry has consistently secured a stronger competitive edge over its Indian counterpart.The Chinese service industry’s comparative competitiveness is weaker than India’s simply because the Chinese manufacturing industry has grown at a faster pace.Last but not least,this paper conducts an in-depth analysis of the causes of competitive difference between China and India in respect of labor quality,infrastructure,government role,social heterogeneity,religion and culture as well as overseas compatriots.

Inter-Regional Comparisons on the Quaternary Large Mammalian Faunas between China and Sub-Saharan Africa

The current and dominant theory about the origin of modern humans is the out-of-Africa hypothesis, which asserts that populations of Homo sapiens left Africa 100,000 years ago and replaced indigenous populations of humans in Eurasia. Many scholars equated the out-of-Africa dispersal of humans with paleoenvironmental changes. However, until now, few have paid special attention to the faunal data and whether or not faunal patterns are supportive of the popular theory. Recent comparative study of the Chinese fauna shows that the communication of faunas between Africa and East Asia could have occurred during the Neogene, but it was very limited during the Pleistocene. In the Chinese Quaternary fauna, only 16% of the genera are also present in the sub-Saharan African fauna. There is also no element among the dominant taxa of the Chinese Quaternary fauna which can be related to the African fauna. There is no reliable proof for the existence of Hippopotamus and Giraffa, as well as Panthera leo, during the Quaternary in China. Two controversial taxa are Acinonyx and Crocuta, about which there is still argument concerning their species identification in Eurasia. It is possible that both of the genera have co-specific taxa in Africa and Eurasia. Although the two genera are confined to Africa today, they did have a long evolutionary history in China. For the Out of Africa hypothesis for Homo sapiens, the implications of the limited faunal interchanges between China and Africa are not completely clear yet.

Comparison of Ten Potential Evapotranspiration Models and Their Attribution Analyses for Ten Chinese Drainage Basins

Potential evapotranspiration(EPET)is usually calculated by empirical methods from surface meteorological variables,such as temperature,radiation and wind speed.The in-situ measured pan evaporation(ETpan)can also be used as a proxy for EPET.In this study,EPET values computed from ten models are compared with observed ETpan data in ten Chinese river basins for the period 1961−2013.The daily observed meteorological variables at 2267 stations are used as the input to those models,and a ranking scheme is applied to rank the statistical quantities(ratio of standard deviations,correlation coefficient,and ratio of trends)between ETpan and modeled EPET in different river basins.There are large deviations between the modeled EPET and the ETpan in both the magnitude and the annual trend at most stations.In eight of the basins(except for Southeast and Southwest China),ETpan shows decreasing trends with magnitudes ranging between−0.01 mm d−1 yr−1 and−0.03 mm d−1 yr−1,while the decreasing trends in modeled EPET are less than−0.01 mm d−1 yr−1.Inter comparisons among different models in different river basins suggest that PETHam1 is the best model in the Pearl River basin,PETHam2 outperforms other models in the Huaihe River,Yangtze River and Yellow River basins,and PETFAO is the best model for the remaining basins.Sensitivity analyses reveal that wind speed and sunshine duration are two important factors for decreasing EPET in most basins except in Southeast and Southwest China.The increasing EPET trend in Southeast China is mainly attributed to the reduced relative humidity.

Comparative study of China and USA public private partnerships in public transportation

As an effective alternative approach to provide goods and services for public infrastructure, the Public Private Partnership （PPP） has been studied extensively over the past few decades. On a global scale, China and the United States have developed cooperation on PPP projects in various areas. To perform a comparative study, this paper analyzes how PPP projects work in both countries for public transportation. The basic features, types, and phases of PPPs in public transportation are introduced first, fol- lowed by a thorough discussion on their advantages and challenges. This paper adopts a case study method to analyze the achievements and problems of PPP projects in both countries and then proposes important findings and suggestions for future research.

A comparison of tectonic ambient shear stress value in China with that in western USA

A method is proposed to estimate average tectonic ambient shear stress value for a region. Thus the average stress values of 19 regions in western USA, and 43 regions (each region is 1010) in Chinese mainland and its surroundings have been obtained. The data of 15 993 earthquakes are from the Internet Centroid Moment Tensor solution made by Harvard University from 1997 to 1999. The results demonstrate that there are highest average stress values in the regions of south California of USA and its off coast sea, reach to 12.0 MPa and 13.7 MPa respectively, then gradually decrease toward north, south, and east. The lowest value is 8.7 MPa and 63% of highest value. The average stress values in northern Xinjiang and in the Chayu region of Tibet are 17.2 and 12.9 MPa respectively. They are highest values in China and higher than USAs. The average stress value in North China, Yunnan, Sichuan, Taiwan is similar to south California of USA. The average stress value in South-North seismic zone is about 13 MPa, a little higher than south California. The distribution of average stress value for two important regions provides basic data for geology. These results are useful to research earthquake activity background and attenuation relation of strong ground motion parameters (e.g. peak acceleration and response spectra).

Visualizing Patterns and Differences in Fine Particulate Matter(PM2.5) Research Between the USA and China over Last 25 Years: A Bibliometric Analysis

To reveal patterns in scientific research results and compare differences in studies on fine particulate matter (PM_(2.5)) between China and the USA, 6608 publications from 1992 to 2016 were collected from the Science Citation Index Expanded (SCI-E)databaseandanalyzedbybibliometrics.Histcite^(TM), Bib Excel1.0.0.0, Net Draw and VOSviewer were used for statistical and visual analysis during this study. Publication outputs, journals, institutions, authors and author keywords were all analyzed to identify publication patterns, research hotspots and research trends. Based on this study, the number of publications produced in future years is expected to be at least twice that in 2016. The number of publications in China and the USA increased annually from 1992 through2014, promoted by improved social and economic conditions. Gross domestic product (GDP) was significantly positively correlated with the number of annual articles published in China and the USA (p<0.05). Through comparative analysis, it was observed that the output of publications in the USA before 2014 was larger than that in China. The total output of PM2.5-related publications in China increased rapidly and far exceeded that in the USA after 2014. It is predicted that the leading region for research on PM2.5 in the future would be China. Analysis of author keywords indicated that"chemical composition"and"source allocation"were the main research hotspots in China and the USA. This research on exposure would be valuable in the future because of the pollution problem in China.Moreover, patterns and differences in scientific outcomes were revealed in this study and this study might provide potential guidelines for future research and management.

A comparison analysis between developed and undeveloped depressions over the South China Sea

-- In this paper, by using two sets of composite data of developed and undeveloped depressions over the South China Sea, we analyze and compare the dynamic structures, the heating fields and the vorticity budget residuals of two different types of depressions. Our conclusions are as follows:The two types of depressions are similar in thermodynamical and dynamical structures. The main differ ences are : in the high layer of developed depression there is a divergence field, with a center near the zero line of vertical wind shear, and over undeveloped depression, the divergence field is weaker and the vertical wind at its center is greater than 5 m s-1. The thermodynamical field of the former is asymmetrical and that of the latter is quasi - symmetrical. As far as the dynamics structure is concerned, the convergence in the lower layer and the difference of divergence between the upper and lower layers of developed depression is three tmies larger than that of undeveloped depression. The upward motion and heating field at the center of developed depression is also stronger than that of undeveloped one.The vorticity budget of the two types of depressions is mainly determined by the divergence term, the vorticity advection term and the vertical transport term. The residual term is also important.The principal contribution comes from the divergence term . This is more significant for developed depression than for undeveloped depression.

A COMPARISON OF DOMESTIC FINANCE IN CHINA AND AMERICA(Summary)

The purpose of this report is to help people to realize the reform of domestic finance in China and the differences of Chinese domestic finance vis-a-vis that of the United States. The domestic finance in China has been developing rapidly in recent years, so nothing has a stable status as we observe the sphare of domestic finance in China. However, as long as we know its nature and development, whatever the status may be in the future, we are still able to know the main distinctions between the two domestic

INVERSION OF TEMPERATURE FROM AMSU-A AND ITS APPLICATION ON WARM-CORE OF TROPICAL DEPRESSION OVER THE SOUTH CHINA SEA

The linear regression and horizontally stepwise correction are conducted on the observational data from AMSU-A L1 B of NOAA polar orbit satellite to invert a 40-layers(from 1,000 h Pa to 0.1 h Pa) dataset of atmospheric temperature with a horizontal resolution of 0.5°×0.5° after the correction of satellite antenna pattern and limb adjustment. Case study shows that the inversion data of temperature can reveal the detail structure of warm core in tropical cyclone. We choose two categories of tropical depressions(TDs) over the South China Sea, including the non-developing TDs and developing TDs. Both of them are developed downward from the middle and upper level to the lower level. Comparison between the evolutions of warm core in the two categories of TDs indicates that the warm core is developed downward from the middle and upper troposphere to the sea surface in all the downward-developing TDs. The difference is that in the group of further developing TDs, the warm core in the upper troposphere is intensified suddenly when it is extending to the sea surface. The warm core in the upper and lower troposphere is strengthened in a meantime. But the similar feature is not observed in the non-developing TDs. Then it may be helpful to judge the TD development by monitoring the change in its warm-core structure.
