    Full Text Available Objectives. We report the single-incision laparoscopic cholecystectomy (SILC learning experience of 2 hepatobiliary surgeons and the factors that could influence the learning curve of SILC. Methods. Patients who underwent SILC by Surgeons A and B were studied retrospectively. Operating time, conversion rate, reason for conversion, identity of first assistants, and their experience with previous laparoscopic cholecystectomy (LC were analysed. CUSUM analysis is used to identify learning curve. Results. Hundred and nineteen SILC cases were performed by Surgeons A and B, respectively. Eight cases required additional port. In CUSUM analysis, most conversion occurred during the first 19 cases. Operating time was significantly lower (62.5 versus 90.6 min, P = 0.04 after the learning curve has been overcome. Operating time decreases as the experience increases, especially Surgeon B. Most conversions are due to adhesion at Calot’s triangle. Acute cholecystitis, patients’ BMI, and previous surgery do not seem to influence conversion rate. Mean operating times of cases assisted by first assistant with and without LC experience were 48 and 74 minutes, respectively (P = 0.004. Conclusion. Nineteen cases are needed to overcome the learning curve of SILC. Team work, assistant with CLC experience, and appropriate equipment and technique are the important factors in performing SILC.

    We present Spin-SILC, a new foreground component separation method that accurately extracts the cosmic microwave background (CMB) polarisation E and B modes from raw multifrequency Stokes Q and U measurements of the microwave sky. Spin-SILC is an internal linear combination method that uses spin wavelets to analyse the spin-2 polarisation signal P = Q + iU. The wavelets are additionally directional (non-axisymmetric). This allows different morphologies of signals to be separated and therefore the cleaning algorithm is localised using an additional domain of information. The advantage of spin wavelets over standard scalar wavelets is to simultaneously and self-consistently probe scales and directions in the polarisation signal P = Q + iU and in the underlying E and B modes, therefore providing the ability to perform component separation and E-B decomposition concurrently for the first time. We test Spin-SILC on full-mission Planck simulations and data and show the capacity to correctly recover the underlying cosmological E and B modes. We also demonstrate a strong consistency of our CMB maps with those derived from existing component separation methods. Spin-SILC can be combined with the pseudo- and pure E-B spin wavelet estimators presented in a companion paper to reliably extract the cosmological signal in the presence of complicated sky cuts and noise. Therefore, it will provide a computationally-efficient method to accurately extract the CMB E and B modes for future polarisation experiments.

    Full Text Available Validation is an essential and important step before the application of remote sensing products. This paper introduces a prototype of the validation network for remote sensing products in China (VRPC. The VRPC aims to improve remote sensing products at a regional scale in China. These improvements will enhance the applicability of the key remote sensing products in understanding and interpretation of typical land surface processes in China. The framework of the VRPC is introduced first, including its four basic components. Then, the basic selection principles of the observation sites are described, and the principles for the validation of the remote sensing products are established. The VRPC will be realized in stages. In the first stage, four stations that have improved remote sensing observation facilities have been incorporated according to the selection principles. Certain core observation sites have been constructed at these stations. Next the Heihe Station is introduced in detail as an example. The three levels of observation (the research base, pixel-scale validation sites, and regional coverage adopted by the Heihe Station are carefully explained. The pixel-scale validation sites with nested multi-scale observation systems in this station are the most unique feature, and these sites aim to solve some key scientific problems associated with remote sensing product validation (e.g., the scale effect and scale transformation. Multi-year of in situ measurements will ensure the high accuracy and inter-annual validity of the land products, which will provide dynamic regional monitoring and simulation capabilities in China. The observation sites of the VRPC are open, with the goal of increasing cooperation and exchange with global programs.

    To assess the accuracy of remote sensing product (RSP) requires well designed and carefully implemented validation effort. However, validation is not a straightforward task. On the contrary, it is generally recognized as a challenging issue due to the inconsistence of resolutions and extents associated with various products, strong spatial and temporal variations of surface parameters and, the essential heterogeneity of land surfaces. Thus, to develop, design and conduct reasonable validation schemes and activities to acquire ground truth at pixel scale over heterogeneous land surfaces is urgently needed. This contains, from the perspective of measurement, to integrate various ground observations collected at multi-scale, in order to validating different RSPs from site to network, especially for those land surface variables with strong spatial-temporal variations. To this end, a dedicated validation initiative has been launched in China since 2011. The main scientific objectives and research contents of this project are to develop mathematical approaches for in situ sampling design to acquire ground truth at pixel scale over heterogeneous land surfaces, to form a series of recognized and practicable technical specifications to guide users to validate various RSPs, and to establish a prototype of national validation network and a RSP evaluation system. Specific validation activities, such as the HiWATER, were conducted from site to network, through multi-scale observations collected from multi-platform and multi-source, to experimentally examine those proposed methodologies and guidelines. Corresponding research outcomes on the development of sampling design, scale method and validation of land surface variables have already yielded. This enables validation efforts to be more effective for heterogeneous land surfaces and applicable for other validation tasks beyond local and regional scale. Following the experience of these validation exercises, we are coordinating

    We have successfully developed a new quantitative analytical ITAT-based SILC model which can explain both of the two field dependencies, i.e. Fowler-Nordheim (FN)-field and the direct tunneling (DT)-field dependent of A-mode and B-mode SILCs. While DT-field dependence of A-mode comes from the single trap assisted tunneling, FN-field dependence of B- mode originates at the tunneling via the multi-trap leakage path. We have also developed an analytical model for the anomalous SILC of the flash memory cell and investigate the properties of retention lifetime of failure bits. The anomalous SILC shows the DT-field dependence because of the tunneling via the incomplete multi-trap path. A remarkable behavior of retention characteristics predicted by our models is a nearly logarithmic time dependence. The Fowler- Nordheim tunneling model leads to an overestimation of lifetime at low Vth region. To take into account a position of each trap and clarify the detail characteristics of SILC, we have proposed a new Monte Carlo like approach for hopping conduction and successfully explained the anomalous SILC using only physical based parameters.

    CERN Document Server

    Rogers, Keir K; Leistedt, Boris; McEwen, Jason D; Pontzen, Andrew

    2016-01-01

    We present new clean maps of the CMB temperature anisotropies (as measured by Planck) constructed with a novel internal linear combination (ILC) algorithm using directional, scale-discretised wavelets --- Scale-discretised, directional wavelet ILC or SILC. Directional wavelets, when convolved with signals on the sphere, can separate the anisotropic filamentary structures which are characteristic of both the CMB and foregrounds. Extending previous component separation methods, which use the frequency, spatial and harmonic signatures of foregrounds to separate them from the cosmological background signal, SILC can additionally use morphological information in the foregrounds and CMB to better localise the cleaning algorithm. We test the method on Planck data and simulations, demonstrating consistency with existing component separation algorithms, and discuss how to optimise the use of morphological information by varying the number of directional wavelets as a function of spatial scale. We find that combining t...

    We present new clean maps of the cosmic microwave background (CMB) temperature anisotropies (as measured by Planck) constructed with a novel internal linear combination (ILC) algorithm using directional, scale-discretized wavelets - scale-discretized, directional wavelet ILC or Scale-discretised, directional wavelet Internal Linear Combination (SILC). Directional wavelets, when convolved with signals on the sphere, can separate the anisotropic filamentary structures which are characteristic of both the CMB and foregrounds. Extending previous component separation methods, which use the frequency, spatial and harmonic signatures of foregrounds to separate them from the cosmological background signal, SILC can additionally use morphological information in the foregrounds and CMB to better localize the cleaning algorithm. We test the method on Planck data and simulations, demonstrating consistency with existing component separation algorithms, and discuss how to optimize the use of morphological information by varying the number of directional wavelets as a function of spatial scale. We find that combining the use of directional and axisymmetric wavelets depending on scale could yield higher quality CMB temperature maps. Our results set the stage for the application of SILC to polarization anisotropies through an extension to spin wavelets.

    The Chinese Sun Hazemeter Network(CSHNET)provides the necessary ground-based observation to validate and assess the applicability of MODIS aerosol optical depth(AOD)products over different ecological and geographic regions in China for the first time.The validation results show that the comprehensive utilization ratio and applicability of MODIS products varied very much over different regions and seasons from August 2004 to July 2005.On the Tibetan Plateau,the comprehensive utilization ratio of MODIS data was low:MODIS products only accounted for 16% of the ground-based observation;on average,31% to 45% of MODIS products fell within the retrieval errors issued by NASA.A similar result was found in northern desert areas with the ratio of MODIS to observation ranging from 15% to 55%,with 7% to 39% of MODIS products within errors.In the remote northeast corner of China,low ratios of MODIS to observation were also found ranging from 14% to 46%,with 49% to 69% of MODIS within errors.The forested sites exhibited moderate ratios of MODIS to observation ranging from 46% to 65%,with 30% to 59% of MODIS within errors.This was similar to numbers observed at sites along eastern seashore of China and inland urban sites with the ratio of MODIS to observation between 63% to 75%,with 25% to 67% of MODIS within errors for sites along eastern seashore of China and 43% to 78%,with 35% to 75% of MODIS within errors for inland urban sites.The ratio of MODIS to observation over agricultural areas ranged from 61% to 89%;59%-88% of MODIS fell within the retrieval errors.At homogeneous and well vegetated areas,the comprehensive utilization ratio of MODIS products was over 80% and above 70% of MODIS products fell within the retrieval errors in growing Season.

Using the latest available EU-SILC data set, a positive relation between these two variables is found across the whole distribution by means of a quartile regression (QR approach. Such effect is stronger effect at the highest quartiles than at the lowest. This result corroborates the possibilityof an increase in the wage dispersion when higher educational attainments are achieved and it is found to be rather robust as showed by linear hypothesis tests. Finally, the country-specific results highlight that the OLS technique misleads relevant information over cross-countries heterogeneity in the impact ofeducation on within group inequality at different points of the wage distribution compared to the QR approach.

    The quality of a newly merged soil moisture product (ECV_SM v0.1) from active and passive microwave sensors has attracted widespread international attention. The performance evaluation of this product will benefit studies on climate, meteorology, agriculture, hydrology, ecology and the environment. In this study, meteorological station data and the Noah soil moisture product were used to validate the ECV_SM product in China. First, some conventional statistical measures, such as correlation coefficients, bias, root mean square difference (RMSD) and mean relative error (MRE), were computed to describe the level of agreement between the meteorological station data and ECV_SM values. The accuracy was moderately high (the correlation was significant at the 0.05 level), although the two datasets differed slightly for various types of land cover. Compared with cropland and urban and built-up areas, the performance of ECV_SM was best in grassland regions. Second, the triple collocation technique was used to assess the random error in the meteorological station data, Noah soil moisture product and ECV_SM product. The mean errors in these three datasets were 0.108, 0.079 and 0.075 m3 m-3, respectively, on July 8, 2010 and 0.099, 0.061 and 0.059 m3 m-3, respectively, on October 8, 2010. Only two days of data were used for the triple collocation test as a representative, but this cannot precisely indicate that the test results on any other day correspond with the test results on these two days. Additionally, a trend analysis of ECV_SM during 2003-2010 was carried out using the Mann-Kendall trend test.

    Freshwater ecoregion is currently widely used by biologists, conservators and resource managers. Most of ecoregion delineations are developed at the basin scale and are not fully adapted in a practical manner because operational water resources management is primarily conducted by political administrative departments. In this study, an ecoregion delineation framework was proposed to classify three-level ecoregions in Jinan City with geographic information systems and cluster analysis. The first level ecoregion was composed of three watersheds (a part of the Yellow River, Xiaoqing River and Tuhaimajia River) plus the urban area, which was primarily determined on the basis of the city administrative divisions and river watersheds. The classification of the second level ecoregion is primarily based on the spatial heterogeneity of land use. The third level ecoregion was delineated for each second level ecoregion by using the cluster analysis on water quality. At the same time, administrative boundaries were used to rectify the boundaries of each ecoregion in this study to facilitate the administration of each ecoregion. Furthermore, ecological health assessment (IBI) based on fish communities were employed to validate the freshwater ecoregion. The results demonstrated that 73.3% of ecoregions were in line with the distribution of fish IBI, indicating that the freshwater ecoregions are acceptable for future water resources management.

  18. Varying association between education and second births in Europe: Comparative analysis based on the EU-SILC data

    2014-10-01

    Full Text Available Background: Previous research has shown considerable variation in the relationship between women's educational attainment and second births in contemporary Europe. A negative association is found in some countries, while a positive or non-negative relationship is reported in others. Existing studies come mainly from single-country perspectives, which renders the results not strictly comparable. Objective: We investigate the association between women's and their partners' educational attainment and transition to second births comparatively in regions and sub-regions of Europe. Methods: The data come from the 2005 and 2011 waves of the EU Statistics on Income and Living Conditions (EU-SILC. We estimate separate discrete-time event history models for regions and sub-regions and multilevel models for all EU-SILC countries. Results: Northern Europe exhibits a positive association between women's and their partners' education and second childbearing. Western Europe features a positive relationship among partners but demonstrates a U-shaped pattern among women. This pattern occurs due to German-speaking countries where women's educational attainment appears inversely related to second births. A negative relationship between women's education and second childbearing also prevails in Eastern Europe; in some sub-regions it extends to male partners. Except for in Eastern Europe, the time-squeeze adds to the positive effect of women's high education. In Northern Europe it enables highly educated women to wholly catch up with their counterparts with medium and low education as regards the proportion having second births. In Southern Europe, by contrast, the educational gradient turns negative following the consideration of the time-squeeze effect. Conclusions: We conclude that the relationship between educational attainment and second births varies not only by individual country but also by larger geographical area in Europe. Although smaller in scale than

    In this paper, the performance of two operational ocean forecasting systems, the global Mercator Océan (MO) Operational System, developed and maintained by Mercator Océan in France, and the regional South China Sea Operational Forecasting System (SCSOFS), by the National Marine Environmental Forecasting Center (NMEFC) in China, have been examined. Both systems can provide science-based nowcast/forecast products of temperature, salinity, water level, and ocean circulations. Comparison and validation of the ocean circulations, the structures of temperature and salinity, and some mesoscale activities, such as ocean fronts, typhoons, and mesoscale eddies, are conducted based on observed satellite and in situ data obtained in 2012 in the South China Sea. The results showed that MO performs better in simulating the ocean circulations and sea surface temperature (SST), and SCSOFS performs better in simulating the structures of temperature and salinity. For the mesoscale activities, the performance of SCSOFS is better than MO in simulating SST fronts and SST decrease during Typhoon Tembin compared with the previous studies and satellite data; but model results from both of SCSOFS and MO show some differences from satellite observations. In conclusion, some recommendations have been proposed for both forecast systems to improve their forecasting performance in the near future based on our comparison and validation.

    Research on students' views on nature of science (VNOS) in Asian countries such as China is notably lacking. This study aimed to develop and validate an instrument to measure South China high school students' VNOS. Based on the previously acquired qualitative data, the instrument included seven VNOS dimensions which reflect the crucial aspects of NOS indicated by the literature and/or the dominating ideology in China (i.e., Marxism). A sample (N = 604) was randomly divided into two groups used for exploratory analyses and confirmatory analyses. The results indicated that the instrument expressed satisfactory reliability and validity and the seven NOS dimensions could be explained by a higher-order dimension. That is, the data of this study supported the multi-dimensional framework that treats VNOS as comprising several more-or-less correlated dimensions. Two distinct dimensions, namely "Accumulative-Empirical Source" and "Pragmatic Justification" which have not been explicitly specified in the past literature, were found. In addition, the Chinese high school students generally held a constructivist/relativist-oriented view of all seven dimensions. Differences in gender and grade level were hardly observed in any dimension of the instrument. The findings are further discussed through a socio-cultural lens to enrich the current understanding of VNOS.

    The gap between the demand and delivery of mental health services in mainland China can be reduced by validating freely available and psychometrically sound psychological instruments. The present research examined the Chinese version of the 21-item Depression Anxiety Stress Scales (DASS-21). Study 1 administered the DASS-21 to 1,815 Chinese college students and found internal consistency indices (Cronbach's alpha) of .83, .80, and .82 for the Depression, Anxiety, and Stress subscales, respectively, and .92 for the total DASS total. Test-retest reliability over a 6-month interval was .39 to .46 for each of the 3 subscales and .46 for the total DASS. Moderate convergent validity of the Depression and Anxiety subscales was demonstrated via significant correlations with the Chinese Beck Depression Inventory (r = .51 at Time 1 and r = .64 at Time 2) and the Chinese State-Trait Anxiety Inventory (r = .41), respectively. Confirmatory factor analyses supported the original 3-factor model with 1 minor change (nonnormed fit index [NNFI] = .964, comparative fit index [CFI] = .968, and root mean square error of approximation [RMSEA] = .079). Study 2 examined the clinical utility of the Chinese DASS-21 in 166 patients with schizophrenia and 90 matched healthy controls. Patients had higher Depression and Anxiety but not Stress subscale scores than healthy controls. A discriminant function composed of the linear combination of 3 subscale scores correctly discriminated 69.92% of participants, which again supported the potential clinical utility of the DASS in mainland China. Taken together, findings in these studies support the cross-cultural validity of the DASS-21 in China. (PsycINFO Database Record PMID:26619091

    The Advanced Along-Track Scanning Radiometer (AATSR) aboard on ENVISAT has been used to observe the Earth for more than 10 years since than 2002. One of main applications of AATSR instrument is to observe atmospheric aerosol, especially in retrieval of aerosol optical depth (AOD), taking advantage of its dual-view that helps to separate the contribution of aerosol from top of atmosphere reflectance (A. A. Kokhanovsky and de Leeuw, 2009). The project of Aerosol_CCI, as part of European Space Agency's Climate Change Initiative (CCI), has released new AATSR aerosol AOD products by the of 2015, including the SU v4.21 product from Swansea algorithm, ADV v2.3 product from the ATSR-2/AATSR dual view aerosol retrieval algorithm (ADV) and ORAC v03.04 product from the Oxford-RAL Retrieval of Aerosol and Cloud algorithm. The previous versions of these three AOD level 2 (L2) products in 2008 have been validated over mainland China (Che and Xue, 2015). In this paper, we validated these AATSR AOD products with latest versions in mainland China in 2007, 2008 and 2010 by the means of comparison with the AErosol RObotic NETwork (AERONET) and the China Aerosol Remote Sensing Network (CARSNET). The combination of AERONET and CARSNET helps to make up for the disadvantages of small number and uneven distribution of AEROENT cites. The validation results show different performance of these AOD products over China. The performances of SU and ADV products seem to be the same with close correlation coefficient (CC) about 08~0.9 and root mean square (RMS) within 0.15 in all three years, and sensitive to high AOD values (AOD >1): more AODs and more underestimated. However, these two products do exist difference, which is that the SU algorithm retrieves more high AODs, leading to more space-time validation matches with ground-based data. The ORAC algorithm is different from the others, it can be not only used to retrieve low AODs but also high AODs over different landcover types. Even though

    Waters along China coast are very turbid with high concentrations of suspended sediment nearly all the time, especially at the Hangzhou Bay, the Changjiang (Yangtze) River Estuary and the shoal along Jiangsu Province. In these turbid and optically complex waters, the standard MODIS ocean color products tend to have invalid values. Because the water-leaving radiances in the near-infrared (NIR) are significant resulting from the strong scattering of suspended particles, the standardMODIS atmospheric correction algorithm often gets no results or produces significant errors. And because of the complex water optical properties, the OC3 model used in the standard MODIS data processing tends to get extremely high chlorophyll-a (Chl-a) concentrations. In this paper, we present an atmospheric correction approach using MODIS short wave infrared (SWIR) bands based on the fact that water-leaving radiances are negligible in the SWlR region because of the extreme strong absorption of water even in turbid waters. A regional Chl-a concentration estimation model is also constructed for MODIS from in situ data. These algorithms are applied to MODIS Aqua data processing in the China coastal regions. In situ data collected in the Yellow Sea and the East China Sea in spring and autumn, 2003 are used to validate the performance. Reasonably good results have been obtained. It is noted that water-leaving reflectance in the NIR bands are significant in waters along the China coast with high sediment loadings. The satellite derived and in-situ reflectance spectra can match in the turbid waters along China coast, and there is relatively good linear relationship between satellite derived and in-situ reflectance. The RMSE value of Rrs(λ)is 0.0031 sr-1 for all the nine ocean color bands (412 to 869 nm). The satellite-derived Chl-a value is in the reasonable range and the root mean square percentage difference is 46.1%.

  7. Validating a dust production model by field experiment in Mu Us Desert, China

    2006-01-01

    Field experiments of dust production have been seldom performed in Chinese deserts that are identified as one of main dust sources in the world, and such an experiment to validate a dust production model (DPM) has not been made in China until now. Saltation flux, dust emission flux, surface features and meteorological parameters (U*, Z0, Ri, etc.) were investigated in Mu Us Desert of China to verify the DPM model and accumulate dust emission data during the spring of 2002. It indicates that observed saltation fluxes from 0.07 to 8.00 g·m-1·s-1 are in good agreement with the ones predicted by the DPM model when the constant of the saltation flux equation is tuned to about 2.61, which corresponds to wind friction velocities from 0.26 to 0.35 m·s-1. Unfortunately, during three local dust emission events, the observed dust fluxes are from 1 to 3μg· m-2· s-1, lower than the modeled ones, implying that the model needs to be improved further under lower wind velocity. In comparison with data from a sandy soil with physical crust and a loam soil, saltation fluxes of the loose sandy soil in Mu Us Desert are obviously higher, which suggests that deserts and sandy land with desertification are major dust sources in northern China.

    Full Text Available The main aim of the article is to analyse the working poor employees and their household's social situation in the national income and living conditions survey (EU-SILC. The analysis starts with the definition of the two main groups of employees according to the number of months spent in the full-time employment - those working whole year and those employed for 6 to 11 months. Poverty in earned income concept is used to evaluate poverty at individual level, confronting employee's income with single person household poverty line benchmark. The study then moves to the household level poverty measure based on household's disposable equivalised income. When shifting from the individual income to the household's one the economies of scale represented by an implicit or explicit equivalence scale used in the construction of the household poverty measure play a crucial role. Therefore, attention is paid to the comparison of poverty level based on equivalised disposable income using equivalence scales and per-capita income. At the end, material deprivation of different subgroups of employees according to their poverty status is examined.

    Full Text Available Abstract: Based on the major dimensions of a communicative language test that Bachman proposed, this paper aims to have an investigation on the validity of the new CET-4 listening subtest in China from a communicative point of view. Both qualitative and quantitative methods are involved in the study. Material analysis falls into qualitative study, including analysis of the CET-4 testing syllabus and eight new CET-4 listening comprehension tests. Students’ scores of two tests and the questionnaires are analyzed quantitatively. Through analysis, it is found that the new CET-4 listening subtest has a high validity and can measure test-takers’ listening ability in real communication. First, the new CET-4 listening subtest has the quality of reliability. Second, the seven listening skills tested in this subtest can measure the communicative language ability required in the testing syllabus. The intra-correlation analysis shows that each part of the new CET-4 listening subtest focuses on different language abilities related to listening. Third, the authenticity of the new CET-4 listening subtest reaches a satisfactory level. The materials chosen in the test cover various topics and genres. Speakers’ pronunciation, tone and speed are in accordance with the real situation. However, some shortcomings also exist in the test design and should be improved later. For example, its limited item types cannot represent the task types in real life, and the actual input is too ideal to be authentic.   Keywords: Communicative language ability, communicative language testing, listening comprehension, test validity

    STRs, scattered throughout the genome with higher mutation rate, are attractive to genetic application like forensic, anthropological and population genetics studies. STR profiling has now been applied in various aspects of human identification in forensic investigations. This work described the developmental validation of a novel and universal assay, the Huaxia Platinum System, which amplifies all markers in the expanded CODIS core loci and the Chinese National Database in one single PCR system. Developmental validation demonstrated that this novel assay is accurate, sensitive, reproducible and robust. No discordant calls were observed between the Huaxia Platinum System and other STR systems. Full genotypes could be achieved even with 250 pg of human DNA. Additionally, 402 unrelated individuals from 3 main ethnic groups of China (Han, Uygur and Tibetan) were genotyped to investigate the effectiveness of this novel assay. The CMP were 2.3094 × 10(-27), 4.3791 × 10(-28) and 6.9118 × 10(-27), respectively, and the CPE were 0.99999999939059, 0.99999999989653 and 0.99999999976386, respectively. Aforementioned results suggested that the Huaxia Platinum System is polymorphic and informative, which provides efficient tool for national DNA database and facilitate international data sharing.

    Full Text Available Introduction. With Chinese health care reform increasingly emphasizing the importance of primary care, the need for a tool to evaluate primary care performance and service delivery is clear. This study presents a methodology for a rapid assessment of primary care organizations and service delivery in China. Methods. The study translated and adapted the Primary Care Assessment Tool-Adult Edition (PCAT-AE into a Chinese version to measure core dimensions of primary care, namely, first contact, continuity, comprehensiveness, and coordination. A cross-sectional survey was conducted to assess the validity and reliability of the Chinese Rapid Primary Care Assessment Tool (CR-PCAT. Eight community health centers in Guangdong province have been selected to participate in the survey. Results. A total of 1465 effective samples were included for data analysis. Eight items were eliminated following principal component analysis and reliability testing. The principal component analysis extracted five multiple-item scales (first contact utilization, first contact accessibility, ongoing care, comprehensiveness, and coordination. The tests of scaling assumptions were basically met. Conclusion. The standard psychometric evaluation indicates that the scales have achieved relatively good reliability and validity. The CR-PCAT provides a rapid and reliable measure of four core dimensions of primary care, which could be applied in various scenarios.

    2008-06-01

    Full Text Available Satellite altimeter data from 1993 to 2005 has been used to analyze the seasonal variation and the interannual variability of upper layer thickness (ULT in the South China Sea (SCS. Base on in-situ measurements, the ULT is defined as the thickness from the sea surface to the depth of 16°C isotherm which is used to validate the result derived from satellite altimeter data. In comparison with altimeter and in-situ derived ULTs yields a correlation coefficient of 0.92 with a slope of 0.95 and an intercept of 6 m. The basin averaged ULT derived from altimeter is 160 m in winter and 171 m in summer which is similar to the in-situ measurements of 159 m in winter and 175 m in summer. Both results also show similar spatial patterns. It suggests that the sea surface height data derived from satellite sensors are usable for study the variation of ULT in the semi-closed SCS. Furthermore, we also use satellite derived ULT to detect the development of eddy. Interannual variability of two meso-scale cyclonic eddies and one anticyclonic eddy are strongly influenced by El Niño events. In most cases, there are highly positive correlations between ULT and sea surface temperature except the periods of El Niño. During the onset of El Niño event, ULT is deeper when sea surface temperature is lower.

    Global time series of the Essential Climate Variable (ECV) soil mositure (SM) is being developed from passive and active satellite microwave sensors at a coarse spatial resolution with Climate Change Initiative program funded by European Space Agency. This study aims to validate the reliability of ECV SM dataset, and attempts are made to analyze SM trends in cropland. Firstly, in-situ SM measurements during crop growing seasons from 1992 to 2010 for 228 stations across China and 21 stations over cropland of North China Plain (NCP) were employed to validate ECV SM product. Then, the spatiotemporal variations of ECV SM were analyzed during growing period of winter wheat (April-June) and summer maize (July-September) from 1981 to 2010 in NCP. Finally, the possible relationship between SM, precipitation, evapotranspiration and NDVI were explored. Results showed that ECV SM could generally capture the seasonal SM dynamics. The average triple collocation random error of ECV SM in China was 0.052 m3 m-3 while the error in cropland ranged from 0.003 to 0.156 m3 m-3. The averaged Spearman correlation coefficient between ECV SM and all in-situ observations was 0.42 (p China and 0.43 (p < 0.01) for cropland over NCP. Spatially, ECV SM was decreasing in most areas during wheat season, whereas the trends of ECV SM were positive in south and negative in north during maize season in NCP, being consistent with the precipitation fluctuation. Overall, ECV SM is potentially suitable for trend analysis in NCP and its validations and analysis will be helpful for further enhancement of the ECV SM product.

    To evaluate the reliability and validity of the Chinese version of addiction severity index (ASl)-5th version (ASI-C-5), in illegal drug users receiving methadone maintenance treatment (MMT) in China. Methods One hundred and eighty-six heroin addicts (144 men and 42 women) receiving MMT at three clinics in Guizhou province, southwest China, were recruited. They were all interviewed with a questionnaire of ASI-C-5 and 35 were re-interviewed at an interval of seven days to assess its test-retest reliability. Results Cronbach's alpha for internal consistency of CSs varied from 0.60 to 0.81 in all domains. Test-retest reliability of composite scores (CSs) of ASI-C-5 were satisfactory (r=0.38-0.97). Based on item analysis and expert's suggestions, five items were deleted and one item was modified in ASI-C-5. Criterion validity of ASI-C-5 was found acceptable, as compared to addicts' self-rating anxiety scale (SAS) and self-rating depression scale (SDS) (r=0.59 and 0.45) except for social support rating scale (SSRS). Conclusions ASI-C-5 can be used for heroin addicts receiving MMT with acceptable reliability and validity.

    AIM: To assess the reliability and validity of the translated version of Nepean Dyspepsia Index (NDI) in Chinese patients with documented functional dyspepsia (FD).METHODS: The translation process included forward translation, back translation, pretest and cross-cultural adaptation. Reliability and validity of the translated version were examined by asking 300 subjects to complete the Chinese version of the NDI. The mean age of subjects was 39.24 years and 68.7% of the subjects were women. Internal consistency analysis with Cronbach's α was performed to test the reliability. Correlation analysis was used to assess the content validity. Factor analysis and structural equation models were used to assess the construct validity.RESULTS: The Cronbach's α coefficients ranged 0.833-0.960, well above the acceptable level of 0.70. Correlation analysis showed that each item had a strong correlation with the corresponding domain, but a weak correlation with other domains. Confirmatory factor analysis indicated that the comparative fit index was 0.94, higher than the acceptable level of 0.90.CONCLUSION: The Chinese version of the NDI is a reliable and valid scale for measuring health-related quality of life and disease severity in Chinese patients with FD.

    Daily increment validation in fish otolith is fundamental to studies on fish otolith microstructure, age determination and life history traits, and thus is critical for species conservation and fishery management. However, it has never been done for Schizothoracine fish, which is the dominant component of fish fauna in the Tibetan Plateau. This study validated the daily increment formation of Gymnocypris selincuoensis, as a representative of Schizothoracine fish, by monitoring the growth of hatchery-reared larvae group and wild-caught post-yolk-sac larvae group under controlled experiments. The results from monitoring the hatchery-reared larvae group showed that sagittae and lapilli were found in yolk-sac larvae, and formed 5-7 days before hatching, but asterisci were not found until 11 days post-hatching. The first increment in sagittae and lapilli was formed in the first day after hatching. The daily periodicity of increment formation was examined and confirmed in sagittae and lapilli of both larvae groups. However, sagittae were better for age determination than lapilli for larvae at earlier days. For larval G. selincuoensis older than 50 days, lapilli were the only otolith pair suitable for larvae daily age determination. This study validated the daily increment formation in Schizothoracine fish for the first time has primary implications to other fishes from this subfamily. PMID:26380660

  6. Validity of the Bouchet's complementary relationship at 102 observatories across China

    YU JingJie; ZHANG YongQiang; LIU ChangMing

    2009-01-01

    Bouchet in 1963 hypothesized that for large homogeneous land surface with minimum advection of heat and moisture, there exists a 1:1 complementary relationship of potential and actual evaporation coupled through land-atmosphere feedbacks. The complementary relationship has been widely used to estimate regional actual evaporation and explain the pan evaporation paradox. We examine the stan-dardized potential evaporation (potential evaporation divided by wet environment evaporation) at 102 observatories at different elevations across China. Generally, the relationship is appropriate at the low elevations (<1000 m). With the increase of elevation, vapor transfer power becomes much less than radiation energy budget because of lower vapor pressure deficit and stronger global solar radiation. As a result, at the high elevations (over 1000 m), the excess energy resulted by limited moisture availability is not enough to be converted into drying power of the air. This result suggests that the complementary relationship is asymmetric at the high elevations.

    The global aerosol optical depth (AOD or τ) has been retrieved using the Dark Target algorithm (the C004 and C005 products) and the Deep Blue algorithm (DB product).Few validations have thus far been performed in arid/semi-arid regions,especially in northwest China.The ground-based remote sensing of AOD from sun photometers at four sites in Xinjiang during the years 2002-2003 is used to validate aerosol products,including C004,C005 and DB of the Moderate Resolution Imaging Spectroradiometer (MODIS).The results show substantial improvement in the C005 aerosol product over the C004 product.The average correlation coefficient of regression with ground measurements increased from 0.59 to 0.69,and the average offset decreased from 0.28 to 0.13.The slopes of the linear regressions tended to be close to unity.The percentage of AODs falling within the retrieval errors of 30% (or △τ =±0.1 ± 0.2τ)increased from 16.1% to 45.6%.The best retrievals are obtained over an oasis region,whereas the worst are obtained over urban areas.Both the MODIS C004 and C005 products overestimate AOD,which is likely related to improper assumptions of the aerosol model and of the estimation of surface reflectance.An encouraging result has been derived with regard to validation of the DB AOD.Overall,the average offset,slope and correlation coefficient of regression with sun-photometer measurements are -0.04,0.88 and 0.85,respectively.Approximately 73% of the DB AOD retrievals fall within the expected error of 30%.Underestimation of the AOD by the DB products is observed.The aerosol model and estimations of surface reflectance in this region require further improvements.

    Perceived stress while driving may affect how critical driving events are handled. The current study validates a Chinese version of the Driver Stress Inventory (DSI) and explores its correlation with dangerous driving behaviors and gender. A sample of 246 drivers completed the Chinese version of the DSI and the Driver Behavior Questionnaire (DBQ). We also evaluated specific sociodemographic variables and traffic violations (including speeding, violating traffic signs or markings, driving while intoxicated, running a red light, and incurring penalty points). A confirmatory factor analysis (CFA) verified the DSI's internal structure. The DSI was also validated using questionnaires related to the DBQ, self-reported traffic accidents and violations, and sociodemographic characteristics. First, all of the DSI dimensions were moderately or weakly correlated with the DBQ subscales. Second, aggression, hazard monitoring and fatigue were weakly correlated with minor accidents. Third, drivers who had sped and violated traffic signs during the previous three years reported higher aggression and thrill seeking, while drivers who had violated traffic signs or markings during the previous three years reported decreased hazard monitoring compared with non-offenders. Finally, there were significant gender differences in driver stress. The Chinese version of the DSI will be useful for classifying and diagnosing drivers who may be at an increased risk for stress reactions. PMID:26642077

    An enthalpy-based frozen soil model was developed for the simulation of water and energy transfer in cold regions. To simulate the soil freezing/thawing processes stably and efficiently, a three-step algorithm was applied to solve the nonlinear governing equations: (1) a thermal diffusion equation was implemented to simulate the heat conduction between soil layers; (2) a freezing/thawing scheme used a critical temperature criterion to judge the phase status and introduced enthalpy and total water mass into freezing depression equation to represent ice formation/melt and corresponding latent heat release/absorption; and (3) a water flow scheme was employed to describe the liquid movement within frozen soil. In addition, a parameterization set of hydraulic and thermal properties was updated by considering the frozen soil effect. The performance of the frozen soil model was validated at point scale in a typical mountainous permafrost basin of China. An ice profile initialization method is proposed for permafrost modeling. Results show that the model can achieve a convergent solution at a time step of hourly and a surface layer thickness of centimeters that are typically used in current land surface models. The simulated profiles of soil temperature, liquid water content, ice content and thawing front depth are in good agreement with the observations and the characteristics of permafrost. The model is capable of continuously reproducing the diurnal and seasonal freeze-thaw cycle and simulating frozen soil hydrological processes.

    Brain attack care is rapidly evolving with cutting-edge stroke interventions similar to the growth of heart attack care with cardiac interventions in the last two decades. As the field of stroke intervention is growing exponentially globally, there is clearly an unmet need to standardize stroke interventional laboratories for safe, effective, and timely stroke care. Towards this goal, the Society of Vascular and Interventional Neurology (SVIN) Writing Committee has developed the Stroke Interventional Laboratory Consensus (SILC) criteria using a 7M management approach for the development and standardization of each stroke interventional laboratory within stroke centers. The SILC criteria include: (1) manpower: personnel including roles of medical and administrative directors, attending physicians, fellows, physician extenders, and all the key stakeholders in the stroke chain of survival; (2) machines: resources needed in terms of physical facilities, and angiography equipment; (3) materials: medical device inventory, medications, and angiography supplies; (4) methods: standardized protocols for stroke workflow optimization; (5) metrics (volume): existing credentialing criteria for facilities and stroke interventionalists; (6) metrics (quality): benchmarks for quality assurance; (7) metrics (safety): radiation and procedural safety practices.

    Objective Diabetes represents a significant challenge for Chinese healthcare providers. Healthcare decision-making is generally based on many data sources, including randomised controlled and real-world studies; however, good-quality data from Chinese diabetes patients are scarce. We performed an initial validation to assess the representativeness of one source of real-world data—the Diabetes Adelphi Disease Specific Programme (DSP) in China. Setting China, UK. Participants The Chinese DSP included 2060 patients with previously diagnosed type 2 diabetes mellitus (T2DM) sampled by 200 physicians. The reference Chinese population comprised 238 639 patients with previously diagnosed T2DM. The UK DSP contained 1481 patients with T2DM sampled by 125 physicians; the reference UK population comprised 289 patients with diabetes. Primary and secondary outcomes The primary outcome was comparison of unweighted China DSP and reference data for sex, body mass index (BMI), blood pressure (BP), patients achieving glycosylated haemoglobin (HbA1c)HbA1c, total cholesterol, smoking and insulin status. Results Comparison of unweighted China DSP and reference data revealed statistical equivalence for BMI, systolic BP, proportion of patients achieving HbA1c HbA1c level were not equivalent, although differences were generally small. Weighting of data did not substantially affect the results. A similar pattern was observed for UK data. Conclusions This study provides evidence that the methodology used for the China and UK parts of the Diabetes DSP produces representative samples that are comparable with other independent sources of patient treatment outcomes data, which may ultimately inform public health decision-making. Although this method could be used in other countries, the current validation applies to UK and China. Further research is required for other countries. PMID:27531722

We determine the tropospheric vertical column densities (VCDs), near surface concentrations and vertical profiles of aerosols, NO2, SO2, HCHO from the MAX-DOAS observations using the optimal estimation profile retrieval algorithm (refered to as "PriAM"). We verified the results by comparing them with results from independent techniques, such as sun photometer (AERONET), a visibility meter and a long-path DOAS instrument. We acquire the cloud and aerosol conditions using a cloud classification scheme based on the MAX-DOAS observations (Wang et al., AMTD, 2015). Based on the obtained results, we characterize the effect of the clouds on the trace gas and aerosol profiles retrieved from MAX-DOAS. Then we characterize the diurnal, annual and weekly variations of the trace gases and aerosols and validate the tropospheric trace gas VCDs derived from the Ozone Monitoring instrument (OMI) on the Aura satellite platform as well as the model results from the IMAGES, CHIMERE and Lotos-Euros models and analyse the agreement depending on the cloud and aerosol conditions. Besides the direct comparison with the satellite data, we also use the trace gas and aerosol profiles derived from MAX-DOAS to recalculate the air mass factor (AMF) for the satellite observations and to evaluate the corresponding improvement of the satellite VCDs. In some periods with strong aerosol pollution, we evaluate the

    This discussion of China focuses on the following: the people; geography; history (early history, 20th century China, the People's Republic of China; the "Great Leap Forward" and the Sino Soviet Split, the Cultural Revolution, and Mao's death and present directions); government (state structure, Chinese Communist Party, and legal system); education; economy; foreign relations; defense; and relations between China and the US. As of 1982, China's population totaled just over 1.008 billion with an annual growth rate of 1.5%. Life expectancy is 68 years. Government authorities endorsed birth control in the 1950s, played it down in 1958, and began to promote it again in 1962. The present family planning program began in the early 1970s and has become more fully mobilized since 1979. The largest ethnic group is the Han Chinese, who constitute 93.3% of the total population. The People's Republic of China, located in eastern Asia, is almost as large as the European continent. 2/3 of China's area is mountainous or semidesert; only about 1/10 is cultivated. China is the oldest continuous major world civilization with records dating back about 3500 years. Mao's death in September 1976 removed a towering figure from Chinese politics and set off a scramble for succession. The post 11th Party Congress leadership has emphasized economic development and renounced the mass political movements of prior years. Important educational reforms were made in early 1978. Since 1979, the Chinese leadership has moved toward more pragmatic positions in almost all fields. The Chinese government has always been subordinate to the Chinese Communist Party (CCP), its role being to implement party policies. The primary instruments of state power are the State Council, an executive body corresponding to a cabinet, and the NPC, a legislative body. China has made impressive progress in primary education since 1949. About 93% of eligible children are enrolled in 1st grade, though only 65% finish primary

    Full Text Available While the current food security is fulfilled in China, the substantial nitrogen fertilizer use has caused many far-reaching environmental problems. Therefore, reforming the fertilizer management is the key toward sustainable agriculture for 1.3 billion people. The present study is intended to test the applicability of a nitrogen fertilizer management approach for corn production developed in U.S. to regions with different climates in China. Through field work, it was found that the so-called Late Season Cornstalk Nitrate Test approach may have to be adapted to dry continental climate and irrigation water conditions, but meanwhile appeared workable under sub-humid warm temperate continental monsoon climate in China. A hypothesis was made to explain the findings and a simple cure was suggested. Moreover, the importance of applying this approach to China was discussed in relation to GHG emission reduction and national fertilizer subsidy policy. Finally, a new fertilizer management scheme was proposed.

    2016-03-01

    Full Text Available The diurnal variation of the suspended sediment concentration (SSC in Hangzhou Bay, China has been investigated using remotely-sensed SSC derived from the Geostationary Ocean Color Imager (GOCI in combination with a coupled hydrodynamic-ecological model for regional and shelf seas (COHERENS. The SSC maps were inferred through a UV-AC atmospheric correction algorithm and an empirical inversion algorithm from the GOCI Level-1B data. The sediment transport model was initialized from maps of the GOCI-derived SSC and the model results were validated through a comparison with remotely-sensed data. The comparison demonstrated that the model results agreed well with the observations. The relationship between SSC distribution and hydrodynamic conditions was analyzed to investigate the sediment transport dynamics. The model’s results indicate that the action of tidal currents dominate the sediment deposition and re-suspension in the coastal waters of the East China Sea. This is especially the case in Hangzhou Bay where the tidal currents are strongest. The satellite-derived sediment data product can not only dramatically improve the specification of the initial conditions for the sediment model, but can also provide valuable information for the model validation, thereby improving the model’s overall performance.

  5. Measuring coverage in MNCH: a validation study linking population survey derived coverage to maternal, newborn, and child health care records in rural China.

    Directory of Open Access Journals (Sweden)

    Li Liu

    Full Text Available BACKGROUND: Accurate data on coverage of key maternal, newborn, and child health (MNCH interventions are crucial for monitoring progress toward the Millennium Development Goals 4 and 5. Coverage estimates are primarily obtained from routine population surveys through self-reporting, the validity of which is not well understood. We aimed to examine the validity of the coverage of selected MNCH interventions in Gongcheng County, China. METHOD AND FINDINGS: We conducted a validation study by comparing women's self-reported coverage of MNCH interventions relating to antenatal and postnatal care, mode of delivery, and child vaccinations in a community survey with their paper- and electronic-based health care records, treating the health care records as the reference standard. Of 936 women recruited, 914 (97.6% completed the survey. Results show that self-reported coverage of these interventions had moderate to high sensitivity (0.57 [95% confidence interval (CI: 0.50-0.63] to 0.99 [95% CI: 0.98-1.00] and low to high specificity (0 to 0.83 [95% CI: 0.80-0.86]. Despite varying overall validity, with the area under the receiver operating characteristic curve (AUC ranging between 0.49 [95% CI: 0.39-0.57] and 0.90 [95% CI: 0.88-0.92], bias in the coverage estimates at the population level was small to moderate, with the test to actual positive (TAP ratio ranging between 0.8 and 1.5 for 24 of the 28 indicators examined. Our ability to accurately estimate validity was affected by several caveats associated with the reference standard. Caution should be exercised when generalizing the results to other settings. CONCLUSIONS: The overall validity of self-reported coverage was moderate across selected MNCH indicators. However, at the population level, self-reported coverage appears to have small to moderate degree of bias. Accuracy of the coverage was particularly high for indicators with high recorded coverage or low recorded coverage but high specificity. The

    Accurate monitoring of the spatiotemporal distribution and variation of snow cover is important for snowmelt runoff simulation and water resources management especially in mountainous areas. In this work, we develop a snow data assimilation scheme based on Ensemble Kalman Filter (EnKF) algorithm and Common Land Model (CoLM), which can assimilate snow cover fraction (SCF) products from the Moderate resolution imaging Spectroradiometer (MODIS) into CoLM for improving snow depth (SD) and snow cover area simulations. An empirical model between SD and SCF has been built based on MODIS SCF and snow depth observations at meteorological stations located in study area, which is used as observation operator in snow data assimilation scheme. The assimilation experiment is conducted during 2004-2007, in Xingjiang province, west China. The preliminary assimilation results are very promising and show that the assimilation of SCF could significantly improve the CoLM capability of simulating snow cover area and snow depth. The assimilation results are more closer to those of observations, which have more reasonable and reliable snow accumulation and melting trends throughout the snow season. After assimilating MODIS SCF observations, the Root Mean Square Error (RMSE) and Mean Bias error (MBE) of snow cover or snow depth are significantly reduced compared to the results without assimilation.

    Full Text Available Model calibration is essential for hydrologic modeling of large watersheds in a heterogeneous mountain environment. Little guidance is available for model calibration protocols for distributed models that aim at capturing the spatial variability of hydrologic processes. This study used the physically-based distributed hydrologic model, MIKE SHE, to contrast a lumped calibration protocol that used streamflow measured at one single watershed outlet to a multi-site calibration method which employed streamflow measurements at three stations within the large Chaohe River basin in northern China. Simulation results showed that the single-site calibrated model was able to sufficiently simulate the hydrographs for two of the three stations (Nash-Sutcliffe coefficient of 0.65–0.75, and correlation coefficient 0.81–0.87 during the testing period, but the model performed poorly for the third station (Nash-Sutcliffe coefficient only 0.44. Sensitivity analysis suggested that streamflow of upstream area of the watershed was dominated by slow groundwater, whilst streamflow of middle- and down- stream areas by relatively quick interflow. Therefore, a multi-site calibration protocol was deemed necessary. Due to the potential errors and uncertainties with respect to the representation of spatial variability, performance measures from the multi-site calibration protocol slightly decreased for two of the three stations, whereas it was improved greatly for the third station. We concluded that multi-site calibration protocol reached a compromise in term of model performance for the three stations, reasonably representing the hydrographs of all three stations with Nash-Sutcliffe coefficient ranging from 0.59–072. The multi-site calibration protocol applied in the analysis generally has advantages to the single site calibration protocol.

    Hoarding disorder, newly included as a separate diagnostic entity in the Obsessive-Compulsive and Related Disorders section of DSM-5, has been reported to have significantly different symptoms and etiology than obsessive-compulsive disorder (OCD). However, the validity of this new diagnosis in China – where the storing of possessions is sanctioned and normalized – remains to be proven. We considered available data about pathological hoarding in East Asia and found the condition to be relatively common and symptomatically similar to that reported in western countries. We conclude that the ‘Hoarding Disorder’ diagnosis defined in DSM-5 is a valid clinical entity in China, though when making the diagnosis clinicians must take care to differentiate pathological hoarding that is distressing to the individual and significantly interferes with social and occupational functioning from culturally sanctioned thriftiness that is not associated with either distress or social dysfunction.%概述:囤积障碍(hoarding disorder),作为新近被纳入DSM-5强迫症和相关障碍部分的一个独立疾病,与强迫症(obsessive-compulsive disorder, OCD)相比具有明显不同的症状和病因。然而,在中国,人们认可储藏个人财物并认为这是正常的,这种新的诊断方法在中国的效度还有待证明。我们研究了东亚地区有关病理性囤积的可用数据,并发现囤积是比较常见的情况,而且出现的症状也类似于西方国家的报道。我们认为, DSM-5中定义的“囤积障碍”在中国是一种合理的临床实体,虽然临床医生在作出该诊断时必须小心区分病理性囤积与文化上所认可的节俭,前者令患者非常痛苦并且明显妨碍其社会和职业功能,而后者与痛苦或社交障碍都不相关的。

    Full Text Available The 3 km Dark Target (DT aerosol optical depth (AOD products, 10 km DT and Deep Blue (DB AOD products from the Collection 6 (C6 product data of Moderate Resolution Imaging Spectroradiometer (MODIS are compared with Sun-sky Radiometer Network (SONET measurements at Song Mountain in central China, where ground-based remote sensing measurements of aerosol properties are still very limited. The seasonal variations of AODs are significant in the Song Mountain region, with higher AODs in spring and summer and lower AODs in autumn and winter. Annual mean AODs (0.55 µm vary in the range of 0.5–0.7, which indicates particle matter (PM pollutions in this mountain region. Validation against one-year ground-based measurements shows that AOD retrievals from the MODIS onboard Aqua satellite are better than those from the Terra satellite in Song Mountain. The 3 km and 10 km AODs from DT algorithms are comparable over this region, while the AOD accuracy of DB algorithm is relatively lower. However, the spatial coverage of DB products is higher than that of 10 km DT products. Moreover, the optical and microphysical characteristics of aerosols at Song Mountain are analyzed on the basis of SONET observations. It suggests that coarse-mode aerosol particles dominate in spring, and fine-mode particles dominate in summer. The aerosol property models are also established and compared to aerosol types used by MODIS algorithm.

    This paper has conducted a short-term national-scale assessment of flood hazards in China based on the theory of natural disaster risks and by means of the powerful spatial analytic tool of GIS, as well as the normalization and analytic hierarchy process. The pre- cipitation of the current day and last three days, topographic elevation, topographic stand- ard deviation, network of rivers and lakes respectively were extracted as assessment factors, the methods of flood hazard factors computation and the models of flood hazard inde xes were advanced, as well as hazard assessment model was built for the national-scale flood hazard. Combined with disasters records, analysis of the minimum and maximum of hazard indexes by statistical method, the flood hazards are divided into four levels: high, medium, low and zero by dividing points of 0.3, 0.45 and 0.6, respectively. Then the model of short-term flood hazard assessment was built and used for a flood hazard assessment on September 14, 2009. It was applied for real-time flood events from June 18 to September 16, 2009 on daily basis. Finally, this paper puts forward the result validation method of flood hazard assessment based on the official report of disaster data. It collects the data from official report of disasters to build the disaster spatial database for the same period of the flood season in 2009, and validates the flood hazard assessment results in the point of view of quantity and area from both county-based and district-based validation u- nit. And the result shows that the rate of correct assessment (i. e. both the hazards and disasters occurrence) is above 65% for counties as the assessment unit and above 84% for districts as the assessment unit in the point of view of quantity. The validation result reveals that short-term national flood hazard assessment conforms basically to the actual disaster data. This model has been successfully applied to the forecast of flood hazards by the Disaster

    Today it makes little sense to ask a question, why social scholars are interested in China’s economy as far as the answer is obvious. The growth rate of Chinese economy and duration of its growth period are stunning. It is likely that in the nearest future China will outrun USA in terms of GDP and become the largest economy in the world. Moreover, China has made a huge progress in GDP per capita. But this is not the only reason for the great interest in China. Chinese communist party is still...

    North China (NC), namely Huabei in Chinese, is one of the most severely polluted regions in China, and the air pollution issues in this region have received a worldwide attention. We performed ground-based Multi Axis Differential Absorption Spectroscopy (MAX-DOAS) measurements at Gucheng, (39°08‧N, 115°40‧E), a rural site of North China about 110 km southwest of Beijing, from September 2008 to September 2010. The tropospheric vertical column densities (VCDs) of NO2 and SO2 were retrieved using the so-called geometric approximation. The results show that the tropospheric NO2 and SO2 VCDs over NC have nearly the same seasonal variation pattern, with the maximum in winter and minimum in summer, while their diurnal variations are different. We also compared the tropospheric NO2 and SO2 VCDs from our MAX-DOAS measurements with several products of corresponding OMI (Ozone Monitoring Instrument) satellite observations. While in summer good agreement is found, the satellite observations systematically underestimate the tropospheric NO2 in winter over the polluted rural area of NC, probably mostly due to the so called aerosol shielding effect. In contrast, for SO2 no such clear conclusion can be drawn, probably owing to the larger uncertainties from MAX-DOAS and in particular satellite retrievals. This indicates that improvements of the retrieval algorithm for MAX-DOAS and off-line corrections of satellite measurements for the tropospheric SO2 VCDs should be given more emphasis in the future.

    This study evaluates the accuracy of total ozone column derived from Ozone Monitoring Instruments (OMI) with two algorithms: OMI Total Ozone Mapping Spectrometer (OMI-TOMS) and OMI Differential Optical Absorption Spectroscopy (OMI-DOAS), compared to ground-based Brewer and Dobson spectrophotometers located at eight China stations from July 2009 to December 2013, including Xianghe, Kunming, Mt.Waliguan, Lhasa, Taipei, Chengkung, Cape D'Aguilar and Longfengshan. Results showed that the agreement between OMI ozone data and ground-based measurements is excellent. Total ozone columns from both OMI-TOMS and OMI-DOAS data are on average about 1.5% lower than ground-based data. For both OMI ozone data products the SZA dependence of the mean relative differences (RD) between satellite data and the ground-based data is relative obvious when the SZA is larger than 50°. Similar to the SZA, the satellite view zenith angle (VZA) dependence of the mean relative differences (RD) between satellite and ground is relatively markedly when the VZA is smaller than 10° in eight stations. Finally, the dependence of the mean relative differences (RD) (-4.28% to 0.818%) between OMI-DOAS data and ground-based data for the total ozone column is remarkable. While for OMI-TOMS data the dependence is not obvious (the RD value varies from -3.30% to -0.676%).

    Climate change is impacting agro-ecosystems, crops, and farmer livelihoods in communities worldwide. While it is well understood that more frequent and intense climate events in many areas are resulting in a decline in crop yields, the impact on crop quality is less acknowledged, yet it is critical for food systems that benefit both farmers and consumers through high-quality products. This study examines tea (Camellia sinensis; Theaceae), the world's most widely consumed beverage after water, as a study system to measure effects of seasonal precipitation variability on crop functional quality and associated farmer knowledge, preferences, and livelihoods. Sampling was conducted in a major tea producing area of China during an extreme drought through the onset of the East Asian Monsoon in order to capture effects of extreme climate events that are likely to become more frequent with climate change. Compared to the spring drought, tea growth during the monsoon period was up to 50% higher. Concurrently, concentrations of catechin and methylxanthine secondary metabolites, major compounds that determine tea functional quality, were up to 50% lower during the monsoon while total phenolic concentrations and antioxidant activity increased. The inverse relationship between tea growth and concentrations of individual secondary metabolites suggests a dilution effect of precipitation on tea quality. The decrease in concentrations of tea secondary metabolites was accompanied by reduced farmer preference on the basis of sensory characteristics as well as a decline of up to 50% in household income from tea sales. Farmer surveys indicate a high degree of agreement regarding climate patterns and the effects of precipitation on tea yields and quality. Extrapolating findings from this seasonal study to long-term climate scenario projections suggests that farmers and consumers face variable implications with forecasted precipitation scenarios and calls for research on management

    We have developed an operational model to simulate water and energy fluxes in the Haihe River Basin (231,800 km2 in size) for the past 28 years. This model is capable of estimating water and energy fluxes of irrigated croplands and heterogeneous grids. The model was validated using actual evapotranspiration (ETa) measured by an eddy covariance system, measured soil moisture in croplands, groundwater level measurements over the piedmont plain and runoff observations in a mountainous catchment. A long-term time series of water and energy balance components were then simulated at a daily time step by integrating remotely sensed information and meteorological data to examine the spatial and temporal distribution and changes in water and energy fluxes in the basin over the past 28 years. The results show that net radiation (Rn) in the mountainous regions is generally higher than that in the plain regions. ETa in the plain regions is higher than that in the mountainous regions mostly because of higher air temperature and larger areas of irrigated farmland. Higher sensible heat flux (H) and lower ETa in the urban areas are possibly due to less vegetation cover, an impervious surface, rapid drainage, and the heat island effect of cities. During the study period, a water deficit continuously occurred in the plain regions because of extensive pumping of groundwater for irrigation to meet the crop water requirements. Irrigation has led to significant groundwater depletion, which poses a substantial challenge to the sustainability of water resources in this basin.

But the test cannot prove that the mutual influence between them exists and the prices overlap, it's necessary to justify whether the two markets are efficiency jointly. Through the Johansen cointegration test and the Granger causality test, it can be proved that the returns of Shanghai has a slight role in prediction on the Shenzhen, however, there is no long-term and harmonious relationship between Shanghai and Shenzhen stock markets. Based on this, the two market are weak efficiency jointly.

    SANSMIC is solution mining software that was developed and utilized by SNL in its role as geotechnical advisor to the US DOE SPR for planning purposes. Three SANSMIC leach modes - withdrawal, direct, and reverse leach - have been revalidated with multiple test cases for each mode. The withdrawal mode was validated using high quality data from recent leach activity while the direct and reverse modes utilized data from historical cavern completion reports. Withdrawal results compared very well with observed data, including the location and size of shelves due to string breaks with relative leached volume differences ranging from 6 - 10% and relative radius differences from 1.5 - 3%. Profile comparisons for the direct mode were very good with relative leached volume differences ranging from 6 - 12% and relative radius differences from 5 - 7%. First, second, and third reverse configurations were simulated in order to validate SANSMIC over a range of relative hanging string and OBI locations. The first-reverse was simulated reasonably well with relative leached volume differences ranging from 1 - 9% and relative radius differences from 5 - 12%. The second-reverse mode showed the largest discrepancies in leach profile. Leached volume differences ranged from 8 - 12% and relative radius differences from 1 - 10%. In the third-reverse, relative leached volume differences ranged from 10 - 13% and relative radius differences were %7E4 %. Comparisons to historical reports were quite good, indicating that SANSMIC is essentially the same as documented and validated in the early 1980's.

    In the field of forensic genetics, essential developmental impulses come from the advances of the molecular biology and human genome projects. This paper overviews existing technologies for forensic genetics in China and gives a perspective of forensic DNA analysis. In China, work has been done in the development of blood group serology of the conventional markers. Forensic scientists in China also contributed to the progress of DNA analysis by the validation of numerous test methods and by optimization of these methods. During these years, forensic DNA analysis in China has experienced tremendous progress towards development of robust, efficient and precise protocols, including the development of short tandem repeat analysis, mitochondrial DNA and Y-chromosome analysis. Forensic scientists are constantly looking for new methods to further improve DNA typing. Therefore, this paper also focuses on emerging new technologies in China, which represent an interest for forensic genetics.

    In recent years, global climate change has become a hot issue concerned and studied by domestic and foreign atmospheric scientists. The change of temperature is the most significant characteristic as well as the most direct consequence of climate change. Extreme weather and climate occurrs more and more frequently in the recent decade, which will have great potential impacts on many regions especially climate-sensitive areas. The research of temperature simulation and validation can help to assess the model applicability systematically as well as can be used as reference for improvment and perfection of the model. The data used in this research come from the simulation results of ten years (2000-2009) obtained by Regional Climate Model and the relevant meteorological observation data from 752 stations. The research methods are mainly mathematical statistics, comparison and analysis as well as correlation validation. In this paper, temperature and its change in the recent decade (2000-2009) in China were first simulated by RegCM3, and then the results were validated preliminarily and analyzed in detail based on meteorological observation data. The results show that the model can simulate the temperature distribution, gradient changes and obvious high temperature centers in general, and the simulation results of central and eastern China are better than western China, such as Qinghai-Tibet Plateau and Sinkiang. The temperature change simulations of 2005-2009 at representative meteorological stations are consistent with those of 2000-2004, which indicates that the model has a certain simulation capability of regional climate change. Further validation shows that the model can simulate the annual and seasonal temperature change as a whole, and the simulation results are better in Northeast China and North China than in other regions. However, there is a phenomenon of systematically low value, especially for high temperature season in northern China and low temperature

    2006-08-01

    Effective management of water resources in arid and semi-arid areas demands studies that cross over the disciplinaries of natural and social sciences. An integrated Hydrological, Ecological and Economical (HEE) modeling system at regional scale has been developed to assess water resources use and ecosystem production in arid and semi-arid areas. As a physically-based distributed modeling system, the HEE modeling system requires various input parameters including those for soil, vegetation, topography, groundwater, and water and agricultural management at different spatial levels. A successful implementation of the modeling system highly depends on how well it is calibrated. This paper presented an automatic calibration procedure for the HEE modeling system and its test in the upper and middle parts of the Yellow River basin. Previous to calibration, comprehensive literature investigation and sensitivity analysis were performed to identify important parameters for calibration. The automatic calibration procedure was base on conventional Monte Carlo sampling method together with a multi-objective criterion for calibration over multi-site and multi-output. The multi-objective function consisted of optimizing statistics of mean absolute relative error (MARE), Nash-Sutcliffe model efficiency coefficient (E NS), and coefficient of determination (R2). The modeling system was calibrated against streamflow and harvest yield data from multiple sites/provinces within the basin over 2001 by using the proposed automatic procedure, and validated over 1993-1995. Over the calibration period, the mean absolute relative error of simulated daily streamflow was within 7% while the statistics R2 and E NS of daily streamflow were 0.61 and 0.49 respectively. Average simulated harvest yield over the calibration period was about 9.2% less than that of observations. Overall calibration results have indicated that the calibration procedures developed in this study can efficiently calibrate

    中国古代逻辑也是研究推理和论证的。推理和论证的主要目的是揭示一个命题为真的原因或理由。推理关系是一种 "必然地得出" 的关系。墨子提出了四种推理模式:"辟"、"侔"、"援"、"推",而且把 "推" 又分为两种 "止",即归纳"止" 式推论和演绎 "止" 式推论。特别地,墨家提出了 "效" 作为判定推理是否有效的标准。%Ancient Chinese logic concerns reasoning and argumentation. The main aim of argumentation is to reveal the reasons for true statements. The relation between the reasons and the statement to be explained is how the truth of the the statement "necessarily comes about"given the reasons. The Mohists advanced four kinds of reasoning pattern: "illustrating (pi,辟)", "parallelizing (mou, 侔)", "adducing (yuan, 援)" and "inferring (tui, 推)". "Inferring"can also be divided into two kinds of "stopping (zhi, 止)", that is to say, inductive and deductive "stopping" inferences. In addition, the Mohists proposed a standard called "xiao (效)" for determining whether or not reasoning is valid.

    Full Text Available A China that is in a frenzied state of economic boom and potential social instability, which is most vividly represented in its architectural and urban developments, is, I hope I will convince you, ephemeral. A quite different China, perhaps is not so visible as its new buildings and cities, is metaphorically ‘handmade’. I should like to extend the meanings of the handmade to the more stable and long lasting attitudes towards social life, and even mortality. My sources for the second China are partially from literature (not from architecture. With the construction boom since the mid-1990s, mainstream Western architectural journals and galleries have been racing to expose new architecture in China; celebrity Western architects have been winning major commissions in China: the 2008 Beijing Olympic Games is a case in point. The sheer quantity and speed of China’s development, as evidenced in architecture and urbanisation, causes an ‘unbearable lightness of being’ (to paraphrase Milan Kundera. Does all this then suggest that China, as solidified in its buildings and cities, is no longer ‘handmade’ in the sense that memory and a sense of history are redundant (particularly for a country that has a recorded history of more than 5000 years, which have been so lovingly recorded in handmade artefacts? The true meaning of the handmade, which absorbs labour — an ‘honourable labour’ as Joseph Conrad lovingly put it in his Mirror of the Sea, as well as memory, like that of a home, is a static artefact, which harbours our changing emotion, the frailties of human life, and indeed, the growing awareness that comes with time of our mortality: the handmade offers the necessary enshrinement of life’s vulnerability. Let me assure you, the seemingly fast-changing China, as represented in its new architecture and city forms, as well in its frenzied urbanisation and booming economy, is but a smoke screen. It is, in other words, ephemeral. The

  3. ESCADRE Code Development and Validation -AN OVERVIEW-

    International Nuclear Information System (INIS)

    The ESCADRE code system (Ensemble de Systems de Codes d'Analyse d'accidents Des Reactors a Eau) is tool designed to help in evaluating the response of nuclear power plants during hypothetical severe accidents. It is an integral code, built with simple engineering models describing major phenomena involved in the accidental sequences; its main objective is to compute the whole sequence, starting from the core uncover right up to the release of fission products outside the plant containment. In the last few years, ESCADRE has been extensively used in France and Eastern countries such as Russia, Hungary, Slovakia, Bulgaria, China, etc...and also modified to match the Russian PWR (WWER) reactors. Since this, ESCADRE has been significantly improved to cope with the needs of French Probabilistic Safety Analysis level 2, which require extensive calculations involving numerous scenarios and parametric studies. A new release, ESCADRE mod 1.1 has been thus developed and is currently used in France and will be soon available for foreign countries. In a first part, new features of ESCADRE mod 1.1 are presented; on the modeling point of view (for example improvement in the core degradation phenomenology description, consideration of Direct Containment Heating phenomena...) and on the mode of use (improved coupling between ESCADRE modules, safety systems management, consideration of events occurring during the accident). A brief description of the new environment of ESCADRE, making this code much more user friendly, is also provided. Second part of the presentation concerns the ESCADRE validation program. The validation is supported by both French and foreign experimental programs. A validation test matrix is presented, showing the experiments used so far for the validation (only the tests for which a validation work has been achieved and documented are mentioned). This validation effort is still in progress. As an illustration, some of the results of this validation work are

This review was performed in response to Corrective Action Request BSC-01-C-01 (Clark 2001, Krisha 2001) pursuant to Quality Assurance review findings of an adverse trend in model validation deficiency. The review findings in this report provide the following information which defines the extent of model validation deficiency and the corrective action needed: (1) AMRs that contain or support models are identified, and conversely, for each model the supporting documentation is identified. (2) The use for each model is determined based on whether the output is used directly for TSPA-SR, or for screening (exclusion) of features, events, and processes (FEPs), and the nature of the model output. (3) Two approaches are used to evaluate the extent to which the validation for each model is compliant with AP-3.10Q (Analyses and Models). The approaches differ in regard to whether model validation is achieved within individual AMRs as originally intended, or whether model validation could be readily achieved by incorporating information from other sources. (4) Recommendations are presented for changes to the AMRs, and additional model development activities or data collection, that will remedy model validation review findings, in support of licensing activities.

  13. Verification and validation benchmarks.

    Energy Technology Data Exchange (ETDEWEB)

    Oberkampf, William Louis; Trucano, Timothy Guy

    2007-02-01

    Verification and validation (V&V) are the primary means to assess the accuracy and reliability of computational simulations. V&V methods and procedures have fundamentally improved the credibility of simulations in several high-consequence fields, such as nuclear reactor safety, underground nuclear waste storage, and nuclear weapon safety. Although the terminology is not uniform across engineering disciplines, code verification deals with assessing the reliability of the software coding, and solution verification deals with assessing the numerical accuracy of the solution to a computational model. Validation addresses the physics modeling accuracy of a computational simulation by comparing the computational results with experimental data. Code verification benchmarks and validation benchmarks have been constructed for a number of years in every field of computational simulation. However, no comprehensive guidelines have been proposed for the construction and use of V&V benchmarks. For example, the field of nuclear reactor safety has not focused on code verification benchmarks, but it has placed great emphasis on developing validation benchmarks. Many of these validation benchmarks are closely related to the operations of actual reactors at near-safety-critical conditions, as opposed to being more fundamental-physics benchmarks. This paper presents recommendations for the effective design and use of code verification benchmarks based on manufactured solutions, classical analytical solutions, and highly accurate numerical solutions. In addition, this paper presents recommendations for the design and use of validation benchmarks, highlighting the careful design of building-block experiments, the estimation of experimental measurement uncertainty for both inputs and outputs to the code, validation metrics, and the role of model calibration in validation. It is argued that the understanding of predictive capability of a computational model is built on the level of

  14. Validation suite for MCNP

    Energy Technology Data Exchange (ETDEWEB)

    Mosteller, R. D. (Russell D.)

    2002-01-01

    Two validation suites, one for criticality and another for radiation shielding, have been defined and tested for the MCNP Monte Carlo code. All of the cases in the validation suites are based on experiments so that calculated and measured results can be compared in a meaningful way. The cases in the validation suites are described, and results from those cases are discussed. For several years, the distribution package for the MCNP Monte Carlo code1 has included an installation test suite to verify that MCNP has been installed correctly. However, the cases in that suite have been constructed primarily to test options within the code and to execute quickly. Consequently, they do not produce well-converged answers, and many of them are physically unrealistic. To remedy these deficiencies, sets of validation suites are being defined and tested for specific types of applications. All of the cases in the validation suites are based on benchmark experiments. Consequently, the results from the measurements are reliable and quantifiable, and calculated results can be compared with them in a meaningful way. Currently, validation suites exist for criticality and radiation-shielding applications.

  15. Containment Code Validation Matrix

    International Nuclear Information System (INIS)

    The Committee on the Safety of Nuclear Installations (CSNI) formed the CCVM (Containment Code Validation Matrix) task group in 2002. The objective of this group was to define a basic set of available experiments for code validation, covering the range of containment (ex-vessel) phenomena expected in the course of light and heavy water reactor design basis accidents and beyond design basis accidents/severe accidents. It was to consider phenomena relevant to pressurised heavy water reactor (PHWR), pressurised water reactor (PWR) and boiling water reactor (BWR) designs of Western origin as well as of Eastern European VVER types. This work would complement the two existing CSNI validation matrices for thermal hydraulic code validation (NEA/CSNI/R(1993)14) and In-vessel core degradation (NEA/CSNI/R(2001)21). The report initially provides a brief overview of the main features of a PWR, BWR, CANDU and VVER reactors. It also provides an overview of the ex-vessel corium retention (core catcher). It then provides a general overview of the accident progression for light water and heavy water reactors. The main focus is to capture most of the phenomena and safety systems employed in these reactor types and to highlight the differences. This CCVM contains a description of 127 phenomena, broken down into 6 categories: - Containment Thermal-hydraulics Phenomena; - Hydrogen Behaviour (Combustion, Mitigation and Generation) Phenomena; - Aerosol and Fission Product Behaviour Phenomena; - Iodine Chemistry Phenomena; - Core Melt Distribution and Behaviour in Containment Phenomena; - Systems Phenomena. A synopsis is provided for each phenomenon, including a description, references for further information, significance for DBA and SA/BDBA and a list of experiments that may be used for code validation.

    Full Text Available The application of games for behavioral change has seen a surge in popularity but evidence on the efficacy of these games is contradictory. Anecdotal findings seem to confirm their motivational value whereas most quantitative findings from randomized controlled trials (RCT are negative or difficult to interpret. One cause for the contradictory evidence could be that the standard RCT validation methods are not sensitive to serious games’ effects. To be able to adapt validation methods to the properties of serious games we need a framework that can connect properties of serious game design to the factors that influence the quality of quantitative research outcomes. The Persuasive Game Design model [1] is particularly suitable for this aim as it encompasses the full circle from game design to behavioral change effects on the user. We therefore use this model to connect game design features, such as the gamification method and the intended transfer effect, to factors that determine the conclusion validity of an RCT. In this paper we will apply this model to develop guidelines for setting up validation methods for serious games.

Today, the state maintains it omnipresence...... in this cultural sector while promoting a policy of dialogue, integration and exclusion. Cooperation with the state is attractive because it is rewarded with unlimited access to official media, audiences and commercial success. The article focuses on recent trends in China’s most important genres of popular music...... attractiveness of the Chinese market. Mandopop and rock music are carefully integrated, while national/international artists and companies engage in self-censorship and thereby support the mainstream ideology.

    This documentation outlines the verification and validation of Shift for the Consortium for Advanced Simulation of LightWater Reactors (CASL). Fivemain types of problems were used for validation: small criticality benchmark problems; full-core reactor benchmarks for light water reactors; fixed source coupled neutron-photon dosimetry benchmarks; depletion/burnup benchmarks; and full-core reactor performance benchmarks. We compared Shift results to measured data and other simulated Monte Carlo radiation transport code results and found very good agreement in a variety of comparison measures. These include prediction of critical eigenvalue, radial and axial pin power distributions, rod worth, leakage spectra, and nuclide inventories over a burn cycle. Based on this validation of Shift, we are confident in Shift to provide reference results for CASL benchmarking.

    Full Text Available In this paper, I respond to the challenge raised against contemporary experimental neurobiology according to which the field is in a state of crisis because of the multiple experimental protocols employed in different laboratories and strengthening their reliability that presumably preclude the validity of neurobiological knowledge. I provide an alternative account of experimentation in neurobiology which makes sense of its experimental practices. I argue that maintaining a multiplicity of experimental protocols and strengthening their reliability are well justified and they foster rather than preclude the validity of neurobiological knowledge. Thus, their presence indicates thriving rather than crisis of experimental neurobiology.

    This ASTER sub-image covers a 12 x 12 km area in northern Shanxi Province, China, and was acquired January 9, 2001. The low sun angle, and light snow cover highlight a section of the Great Wall, visible as a black line running diagonally through the image from lower left to upper right. The Great Wall is over 2000 years old and was built over a period of 1000 years. Stretching 4500 miles from Korea to the Gobi Desert it was first built to protect China from marauders from the north.This image is located at 40.2 degrees north latitude and 112.8 degrees east longitude.Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) is one of five Earth-observing instruments launched December 18, 1999, on NASA's Terra satellite. The instrument was built by Japan's Ministry of International Trade and Industry. A joint U.S./Japan science team is responsible for validation and calibration of the instrument and the data products. Dr. Anne Kahle at NASA's Jet Propulsion Laboratory, Pasadena, Calif., is the U.S. Science team leader; Moshe Pniel of JPL is the project manager. ASTER is the only high resolution imaging sensor on Terra. The primary goal of the ASTER mission is to obtain high-resolution image data in 14 channels over the entire land surface, as well as black and white stereo images. With revisit time of between 4 and 16 days, ASTER will provide the capability for repeat coverage of changing areas on Earth's surface.The broad spectral coverage and high spectral resolution of ASTER will provide scientists in numerous disciplines with critical information for surface mapping, and monitoring dynamic conditions and temporal change. Example applications are: monitoring glacial advances and retreats, monitoring potentially active volcanoes, identifying crop stress, determining cloud morphology and physical properties, wetlands Evaluation, thermal pollution monitoring, coral reef degradation, surface temperature mapping of soils and geology, and measuring surface

    Self-Validating Thermocouple (SVT) Systems capable of detecting sensor probe open circuits, short circuits, and unnoticeable faults such as a probe debonding and probe degradation are useful in the measurement of temperatures. SVT Systems provide such capabilities by incorporating a heating or excitation element into the measuring junction of the thermocouple. By heating the measuring junction and observing the decay time for the detected DC voltage signal, it is possible to indicate whether the thermocouple is bonded or debonded. A change in the thermal transfer function of the thermocouple system causes a change in the rise and decay times of the thermocouple output. Incorporation of the excitation element does not interfere with normal thermocouple operation, thus further allowing traditional validation procedures as well.

In previous research, only two end-users' constructs were used: assurance and responsiveness. In this paper, we extend MEDIQUAL constructs to include reliability, empathy, assurance, tangibles, and responsiveness, which are based on the SERVQUAL theory. The results suggest that: 1) five MEDIQUAL constructs are validated through the factor analysis. That is, importance of the constructs have relatively high correlations between measures of the same construct using different methods and low correlations between measures of the constructs that are expected to differ; and 2) five MEDIQUAL constructs are statistically significant on media users' satisfaction in help desk service by regression analysis.

    An appropriate evaluation methodology is critical in collecting valid data in complex development intervention contexts. This paper explores this issue by putting forward an appropriate evaluation methodology for development interventions in rural China. It draws on the experience of an impact evaluation of a sustainable agricultural biodiversity management project conducted in Hainan, China in 2010. The authors propose that evaluation be culturally responsive and the evaluation design be rooted in the particular cultural context where an evaluation is conducted. The appropriate use of the participatory rural appraisal (PRA) approach and methods helps generate data that are relevant and meaningful for evaluation purposes in rural China. PMID:25045841

Sets of rules, ways to assess the consistency of rules and behavior within the organization are defined. Using ontologies are obtained qualifications that assess the organization's audit. Elaboration of the audit reports is a perfect algorithm-based activity characterized by generality, determinism, reproducibility, accuracy and a well-established. The auditors obtain effective levels. Through ontologies obtain the audit calculated level. Because the audit report is qualitative structure of information and knowledge it is very hard to analyze and interpret by different groups of users (shareholders, managers or stakeholders. Developing ontology for audit reports validation will be a useful instrument for both auditors and report users. In this paper we propose an instrument for validation of audit reports contain a lot of keywords that calculates indicators, a lot of indicators for each key word there is an indicator, qualitative levels; interpreter who builds a table of indicators, levels of actual and calculated levels.

    Vegetation indices (Ⅵ) are one of the standard science products available from the Moderate Resolution Imaging Spectroradiometer (MODIS). Validation of MODIS-Ⅵ products was an important prerequisite to using these variables for global modeling. In this study, validation of the MODIS-VI products including single-day MODIS, level 2 (gridded) daily MODIS surface reflectance (MOD09), 16-day composited MODIS (MOD13) was performed utilizing multisensor data from MODIS, Thematic Mapper (TM), and field radiometer, for a rice-planting region in southern China. The validation approach involved scaling up independent fine-grained datasets, including ground measurement and high spatial resolution imagery, to the coarser MODIS spatial resolutions. The 16-day composited MODIS reflectance and Ⅵ matched well with the ground measurement reflectance and Ⅵ. The Ⅵ of TM and MODIS were lower than the ground Ⅵ. The results demonstrated the accuracy, reliability, and utility of the MODIS-Ⅵ products for the study region.

    Headache disorders are problematic worldwide. China is no different. A population-based door-to-door survey revealed that the 1-year prevalence of primary headache disorders in China was 23.8%, constituting a major societal burden. Many headache centers and clinics have been established in China, and headache disorders (and associated stress) are receiving an increased level of expert attention. This review summarizes the outcomes of the epidemiological survey and the progress of clinical and basic research in China, describes the present situation in terms of headache diagnosis and treatment, and discusses the future of headache care in China.

    Test data on canonical weapon-like fixtures are used to validate previously developed analytical bounding results. The test fixtures were constructed to simulate (but be slightly worse than) weapon ports of entry but have known geometries (and electrical points of contact). The exterior of the test fixtures exhibited exterior resonant enhancement of the incident fields at the ports of entry with magnitudes equal to those of weapon geometries. The interior consisted of loaded transmission lines adjusted to maximize received energy or voltage but incorporating practical weapon geometrical constraints. New analytical results are also presented for bounding the energies associated with multiple bolt joints and for bounding the exterior resonant enhancement of the exciting fields.

    The large amount of work on community detection and its applications leaves unaddressed one important question: the statistical validation of the results. In this paper we present a methodology able to clearly detect if the community structure found by some algorithms is statistically significant or is a result of chance, merely due to edge positions in the network. Given a community detection method and a network of interest, our proposal examines the stability of the partition recovered against random perturbations of the original graph structure. To address this issue, we specify a perturbation strategy and a null model to build a set of procedures based on a special measure of clustering distance, namely Variation of Information, using tools set up for functional data analysis. The procedures determine whether the obtained clustering departs significantly from the null model. This strongly supports the robustness against perturbation of the algorithm used to identify the community structure. We show the r...

    The Dyadic Coping Inventory (DCI, Bodenmann, 2008) assesses how couples support each other when facing individual (e.g., workload) and common (e.g., parenting) stressors. Specifically, the DCI measures partners' perceptions of their own (Self) and their partners' behaviors (Partner) when facing individual stressors, and partners' common coping behaviors when facing common stressors (Common). To date, the DCI has been validated in 6 different languages from individualistic Western cultures; however, because culture can affect interpersonal interactions, it is unknown whether the DCI is a reliable measure of coping behaviors for couples living in collectivistic Eastern cultures. Based on data from 474 Chinese couples (N = 948 individuals), the current study examined the Chinese version of the DCI's factorial structure, measurement invariance (MI), and construct validity of test scores. Using 3 cultural groups (China, Switzerland, and the United States [U.S.]), confirmatory factor analysis revealed a 5-factor structure regarding Self and Partner and a 2-factor structure regarding Common dyadic coping (DC). Results from analyses of MI indicated that the DCI subscales met the criteria for configural, metric, and full/partial scalar invariance across cultures (Chinese-Swiss and Chinese-U.S.) and genders (Chinese men and women). Results further revealed good construct validity of the DCI test scores. In all, the Chinese version of the DCI can be used for measuring Chinese couples' coping behaviors, and is available for cross-cultural studies examining DC behaviors between Western and Eastern cultures.

    This paper focuses on the radiative transfer in stars where opacities seem to raise problems : β-Cephei and solar-type stars. We first concentrate on the iron bump (log T = 5.25), responsible for β-Cephei pulsations through the κ-mechanism. To discriminate between the different opacity calculations used to predict their oscillations, new well-qualified calculations are used and compared to OP calculations. In parallel with this theoretical work, an experiment has been conducted at LULI 2000 in 2011 on iron and nickel. We show that this extended study pushes for the revision of the tables in the conditions corresponding to the iron bump region, at least for nickel. We will then deal with the Sun case for which we are preparing an opacity experiment on a high-energy laser, in some conditions of the radiative zone (T = [2 - 15 ×10^{6} K] and ρ = [0.2 - 150 g/cm^{3}]). To reach these high temperatures and densities at LTE and validate or not plasma effects and line widths, we are exploring an approach called the Double Ablation Front, driven by plasma radiative effects. The 1D simulations performed with the code CHIC show that with this technique, we could reach conditions equivalent to the conditions of half of the solar radiative zone.

    Full Text Available Data validation is becoming more and more important with the ever-growing amount of data being consumed and transmitted by systems over the Internet. It is important to ensure that the data being sent is valid as it may contain entry errors, which may be consumed by different systems causing further errors. XML has become the defacto standard for data transfer. The XML Schema Definition language (XSD was created to help XML structural validation and provide a schema for data type restrictions, however it does not allow for more complex situations. In this article we introduce a way to provide rule based XML validation and correction through the extension and improvement of our SRML metalanguage. We also explore the option of applying it in a database as a trigger for CRUD operations allowing more granular dataset validation on an atomic level allowing for more complex dataset record validation rules.

    Coal fires have a very long history in China; the oldest coal fires have being burning for many million years. Up to now more than 56 coal fires spots were distinguished. They mainly locate in West-North of China, North of China and East-North of China. About millions of tons of coal have been burned in fires every year. Xinjiang Autonomy is the most serious region in coal fires as it has 38 coal fires spots and about 6.85 million tons of coal was burned every year. Coal fires in China ignited by wildfires, spontaneous combustion and human being during mining activities. These fires have released about 0.9 million tons of gasses (including CO, CO2, SO2, NO2 CH4, CO2, H2S etc.) into the atmosphere every year, most of which are brought to the east by wind and resulting more heavier air pollution in northern China.

    International Nuclear Information System (INIS)

    This study reports on conducted experiments and computer simulations of ultrasonic nondestructive testing (NDT). Experiments and simulations are compared with the purpose of validating the simulation program UTDefect. UTDefect simulates ultrasonic NDT of cracks and some other defects in isotropic and homogeneous materials. Simulations for the detection of surface breaking cracks are compared with experiments in pulse-echo mode on surface breaking cracks in carbon steel plates. The echo dynamics are plotted and compared with the simulations. The experiments are performed on a plate with thickness 36 mm and the crack depths are 7.2 mm and 18 mm. L- and T-probes with frequency 1, 2 and 4 MHz and angels 45, 60 and 70 deg are used. In most cases the probe and the crack is on opposite sides of the plate, but in some cases they are on the same side. Several cracks are scanned from two directions. In total 53 experiments are reported for 33 different combinations. Generally the simulations agree well with the experiments and UTDefect is shown to be able to, within certain limits, perform simulations that are close to experiments. It may be concluded that: For corner echoes the eight 45 deg cases and the eight 60 deg cases show good agreement between experiments and UTDefect, especially for the 7.2 mm crack. The amplitudes differ more for some cases where the defect is close to the probe and for the corner of the 18 mm crack. For the two 70 deg cases there are too few experimental values to compare the curve shapes, but the amplitudes do not differ too much. The tip diffraction echoes also agree well in general. For some cases, where the defect is close to the probe, the amplitudes differ more than 10-15 dB, but for all but two cases the difference in amplitude is less than 7 dB. 6 refs

    Objective: The Substance Use Risk Profile Scale (SURPS) has been developed to screen personality risk factors for substance misuse. This scale assesses 4 high-risk personality traits using a 23-item, self-report questionnaire. SURPS helps guiding targeted approaches to prevention of substance abuse and misuse. It has been validated in the United Kingdom, English Canada, Sri Lanka, and China. This study aims to validate this scale in a sample of French-speaking adolescents from Quebec as well as its sensitivity in a clinical sample of adolescents. Method: Two hundred two 15-year-old youths from a community sample completed a French version of SURPS as well as other measures of personality and substance use. This study reports the internal consistency and concurrent validity of the scale, as well as a factor analysis of items. Further, 40 youths (mean age 15.7 years) from a clinical population completed SURPS and their scores were compared with those of the community sample. Results: SURPS French translation has good internal consistency and demonstrated a 4-factor structure very similar to the original scale. The 4 subscales show good concurrent validity, and 3 of the subscales were found to correlate with measures of substance use. Finally, 95% of the clinical sample was identified at high risk for substance misuse according to SURPS cut-off scores. Conclusion: SURPS French translation seems to be a valid and sensitive scale that can be used in a French-speaking adolescent population from Quebec.

    Automated structure validation was introduced in chemical crystallography about 12 years ago as a tool to assist practitioners with the exponential growth in crystal structure analyses. Validation has since evolved into an easy-to-use checkCIF/PLATON web-based IUCr service. The result of a crystal structure determination has to be supplied as a CIF-formatted computer-readable file. The checking software tests the data in the CIF for completeness, quality and consistency. In addition, the reported structure is checked for incomplete analysis, errors in the analysis and relevant issues to be verified. A validation report is generated in the form of a list of ALERTS on the issues to be corrected, checked or commented on. Structure validation has largely eliminated obvious problems with structure reports published in IUCr journals, such as refinement in a space group of too low symmetry. This paper reports on the current status of structure validation and possible future extensions.

    This paper discusses the past and the status quo of electricity securitization in China. First, the stranded cost securitization in American electricity industry and the ongoing securitization progress in emerging market countries are investigated, which enlightens the way of electricity securitization in China. Through analysis of electricity industry in China, the paper proposes constructive policy suggestions for regulators who intend to prompt securitization to develop electricity infrastructure, and detailed recommendations for companies who plan to raise money at reduced cost. It is concluded that even though it is at the very beginning stage in China, securitization not only provides financing for investment projects, but also speeds up the reform by stranded cost securitization, a novel idea for electricity industry in China.

  14. AREVA in China

    International Nuclear Information System (INIS)

    China has a great need for secure, safe, and economic energy supplies that combat the greenhouse effect and global warming. Since January 2002, China, the most heavily populated country with more than 1.3 billion inhabitants in a territory of 9.5 million km2 (17 times larger than France), has a nuclear capacity of 9 GWe with 11 nuclear plants on line. Forecasts of electricity consumption report a need for 900 to 1,000 GWe per year through 2020, and at this time the country's objective is to increase nuclear generated electricity from 1% to 4% of its total output. This means a need for additional 30 GWe, which is the equivalent of twenty 1,500 MWe reactors. In addition to nuclear power, China is pushing renewable energy. With the passage of the 2005 Renewable Energy Law, China's government imposed a national renewable energy requirement that is expected to boost the use of renewable energy capacity from 10 to 12 percent by 2020, up from 3% in 2003. This law requires power operators to buy electricity from alternative energy providers and gives economic incentives to these providers. Consequently, China is expanding its interests in renewable energy sources including wind and bio-energies, among others. It is in this context that AREVA, a world expert in energy, creates and offers solutions to generate, transmit, and distribute electricity for China. Based on its long experience and global presence, AREVA has become the worldwide leader for nuclear energy in the areas of construction, equipment, and services for nuclear power plants, and for the whole nuclear fuel cycle. AREVA is also a world leader in electrical power-grid equipment and systems. This document presents: China's need for energy; the Sources of China's energy mix; the challenges of China's nuclear program; AREVA's action in supporting China's ambitious nuclear program; the strong opportunities in renewable energy; and the high potential market for AREVA's T and D Division

    In order to study the carbon cycling in China deeply, a forest above ground biomass (AGB) estimation research is carried out under the support of 'Strategic Priority Research Program - Climate Change: Carbone Budget and Related Issues' of the Chinese Academy of Sciences (Carbon Project). The research aims to estimate the forest AGB in 2000, 2005 and 2010 in China, and analyzes its dynamic changes. The overall thinking of the research is using field works and airborne LiDAR data as basis to estimate the AGB in GLAS footprints, and then extrapolating discrete AGB to continuous results with optical and auxiliary data. Due to the large area of China, totally 8 sub-areas are marked out based on the different forest ecosystems and some other factors (Table 1 and Fig. 1). Here, a latest China's land cover product (the background of Fig 1), named 'ChinaCover', and also supported by the 'Carbon Project', is imported to classify the forest types. There are around 5000 sample plots (Table 1) surveyed by the 'Carbon Project'. It can provide a large number of training and validation data. At the same time, the research sets 6 other typical sample areas, which have areas of 60 to 200 km2, and airborne LiDAR flights are carried out to obtain high accuracy AGB in these areas. With the sample plots and 6 typical sample areas, the AGB in GLAS footprint is estimated. Since the sample plots and LiDAR flights were carried out in 2012, the height and area parameters extracted from GLAS footprint are corrected by tree growth model of different forest types. In a further step, extrapolation models are built together with time-series MODIS and auxiliary data. These models fully consider the time-series features and propose several long time-series indices to minimize the influence of spectral saturation. Results are validated by samples and compared to the result of some other researches. At last, the models are applied to the data of 2000, 2005 and 2010 to get the corresponding AGB maps

This latest book sets out to address questions of grave importance to China and to the world. The litany of challenges – poisonous water and toxic air, scarcity of water and other resources, deforestation, soil erosion, loss of biodiversity – seem nearly insurmountable, despite evidence of considerable attention from the Chinese government and from China's public, and despite the rocket-like rise of China's economic power and political influence in the world. Shapiro adds to this list the growing problems with lapses in environmental justice, both within China and passed on to its neighbours and to the countries with which it trades. Not only do growing environmental problems affect China's ability to achieve the government's stated goals of a 'harmonious society' with 'moderate prosperity for all,' but these problems, and the ways that ...

  3. China's power policy

    International Nuclear Information System (INIS)

    Whether the People's Republic of China may develop to an economical super-government in future depends on the amount of power and resources of this land. The security of power supply is in an extremely prominent position in the Agenda of the Chinese government. Under this aspect the author of the contribution under consideration reports on the power policy of China. The main aspects of this contribution are: (a) Trends of power consumption, productions and imports of power; (b) Power political targets, measures and instruments of China; (c) Characteristics, national and international impacts of the power policy of China. Due to the economical activities of the chinese oil industry worldwide as well as due to the increasing dependence from imports of petroleum and natural oil, China becomes a global player. Thus, one may expect an intensification of Beijing's economical activities with an increased military component. Nevertheless, the power policy of China is an important factor in the global competition according to fossil resources. In order to understand the future behaviour of China's power policy, one may have to take notice of the strategies relating the power policy and relating to foreign affairs. Furthermore, trends and problematic areas concerning the securitization of the power supply in the national area have to be observed

    ValidNESs (http://validness.ym.edu.tw/) is a new database for experimentally validated leucine-rich nuclear export signal (NES)-containing proteins. The therapeutic potential of the chromosomal region maintenance 1 (CRM1)-mediated nuclear export pathway and disease relevance of its cargo proteins has gained recognition in recent years. Unfortunately, only about one-third of known CRM1 cargo proteins are accessible in a single database since the last compilation in 2003. CRM1 cargo proteins are often recognized by a classical NES (leucine-rich NES), but this signal is notoriously difficult to predict from sequence alone. Fortunately, a recently developed prediction method, NESsential, is able to identify good candidates in some cases, enabling valuable hints to be gained by in silico prediction, but until now it has not been available through a web interface. We present ValidNESs, an integrated, up-to-date database holding 221 NES-containing proteins, combined with a web interface to prediction by NESsential.

Twenty years later, the number of HIV/AIDS patients has risen alarmingly. In 2003, the Chinese Ministry of Health launched an AIDS Epidemiological Investigation across China with the support of the WHO and UN AIDS Program. Its results show that there are currently 840,000 HIV carriers, including 80,000 people with full-blown AIDS, in 31 Chinese provinces, municipalities and autonomous regions. This means China has the second highest number of HIV/AIDS cases in Asia and 14th highest in the world. Statistics from the Chinese Venereal Disease and AIDS Prevention Association indicate that the majority of Chinese HIV carriers are young to middle aged, more than half of them between the ages of 20 and 29.

    Since the end of the Cold War, China's military diplomacy has displayed an omni-directional and multi-level form, and with an increasing transparency which has increased trust and reduced doubt. China has enhanced its conventional military functions and strengthened its military soft power. This has helped China develop into a responsible state on the world stage. Through military exchanges with other countries, the Chinese military has gradually strengthened its ability to undertake a variety of tasks. The Chinese military has to make greater efforts to counter the perception of a "China threat." There is also a need to establish a system of military spokesmen and to develop a theory of military diplomacy with Chinese characteristics.

  13. Orphan Care in China

    Full Text Available Orphan care in China was once provided by the central government as a means of social control. The centralized welfare delivery guaranteed some of the poorest orphans to be protected by the government. Since the economic reform, the central government started to relinquish its control over social welfare delivery, new forms of orphan care were introduced into China, sharing the responsibilities and burdens for caring the orphans. Yet, many issues and problems exist in social delivery due to a lack of finances, professionals, and policy support. In this chapter, we will discuss the background of social welfare changes in China, as pertains to orphan care, focusing on the different types of orphans as a result of social issues, service delivery, barriers and solutions. It is claimed that during the reform, the burden of orphan care in China may not be reduced in the coming future, and we offer suggestions to cope with that.

    Background So far, in China, there has been no effective or easy procedure to define the control of asthma. This study assesses the validity of Asthma Control Test in Chinese patients.Methods Three questionnaires (Asthma Control Test, Asthma Control Questionnaire and the 30 second asthma test)were administered to 305 asthma patients from 10 teaching hospitals across China. Spirometry was also used. Asthma specialists rated the control of asthma according to patients' symptoms, medications and forced expiratory volume in first second. The patients were divided into noncontrolled group and controlled group according to the specialists' rating.Reliability, empirical validity and screening accuracy were conducted for Asthma Control Test scores. Screening accuracy was compared among 3 questionnaires. The patients' self rating and the specialists' rating were also compared.Results The internal consistency reliability of the 5-item Asthma Control Test was 0.854. The correlation coefficient between Asthma Control Test and the specialists' rating was 0.729, which was higher than other instruments. Asthma Control Test scores discriminated between groups of patients differing in the percent predicted forced expiratory volume in first second (F=26.06, P<0.0001), the specialists' rating of asthma control (F=88.24, P<0.0001) and the Asthma Control Questionnaire scores (F=250.57, P<0.0001). Asthma Control Test showed no significant difference with Asthma Control Questionnaire in the percent correctly classified, while the percent correctly classified by Asthma Control Test was much higher than 30 second asthma test. The patients' self rating was the same as assessment of the specialists (t=0.65, P=0.516).Conclusion The Asthma Control Test is an effective and practicable method for assessing asthma control in China.

    The Energy Analysis Program (EAP) at the Lawrence Berkeley Laboratory (LBL) first became involved in Chinese energy issues through a joint China-US symposium on markets and demand for energy held in Nanjing in November of 1988. Discovering common interests, EAP began to collaborate on projects with the Energy Research Institute (ERI) of China`s State Planning Commission. In the course of this work it became clear that a major issue in the furtherance of our research was the acquisition of reliable data. In addition to other, more focused activities-evaluating programs of energy conservation undertaken in China and the prospects for making Chinese industrics morc energy-efficient, preparing historical reviews of cncrgy supply and demand in the People`s Republic of China, sponsoring researchers from China to work with experts at LBL on such topics as energy efficiency standards for buildings, adaptation of US energy analysis software to Chinese conditions, and transportation issues-we decided to compile, assess, and organize Chinese energy data. Preparing this volume confronted us with a number of difficult issues. The most frustrating usually involved the different approaches to sectoral divisions taken in China and the US. For instance, fuel used by motor vehicles belonging to industrial enterprises is counted as industrial consumption in China; only fuel use by vehicles belonging to enterprises engaged primarily in transportation is countcd as transportation use. The estimated adjustment to count all fuel use by vehicles as transportation energy use is quite large, since a large fraction of motor vehicles belong to industrial enterprises. Similarly, Chinese industrial investment figures are skewed compared to those collected in the US because a large portion of enterprises` investment funds is directed towards providing housing and social services for workers and their families.

  9. Validating LES for Jet Aeroacoustics

    Science.gov (United States)

    Bridges, James

    2011-01-01

    Engineers charged with making jet aircraft quieter have long dreamed of being able to see exactly how turbulent eddies produce sound and this dream is now coming true with the advent of large eddy simulation (LES). Two obvious challenges remain: validating the LES codes at the resolution required to see the fluid-acoustic coupling, and the interpretation of the massive datasets that result in having dreams come true. This paper primarily addresses the former, the use of advanced experimental techniques such as particle image velocimetry (PIV) and Raman and Rayleigh scattering, to validate the computer codes and procedures used to create LES solutions. It also addresses the latter problem in discussing what are relevant measures critical for aeroacoustics that should be used in validating LES codes. These new diagnostic techniques deliver measurements and flow statistics of increasing sophistication and capability, but what of their accuracy? And what are the measures to be used in validation? This paper argues that the issue of accuracy be addressed by cross-facility and cross-disciplinary examination of modern datasets along with increased reporting of internal quality checks in PIV analysis. Further, it is argued that the appropriate validation metrics for aeroacoustic applications are increasingly complicated statistics that have been shown in aeroacoustic theory to be critical to flow-generated sound.

    As a part of its inspection strategy for the Sizewell-B PWR station, the Central Electricity Generating Board (in part now Nuclear Electric) decided that the ultrasonic inspection procedures for the incredibility of failure components would be subjected to independent confirmation of their adequacy. The incorporation of validation into a large-scale inspection strategy was unique at the time (1982), indeed remains so today. The CEGB's general philosophy is one of diversity, redundancy and validation. In order to carry out independent validation of the specific procedures and ultrasonic operators to be used during the manufacture and in-service inspection of the reactor pressure vessel and steam plant components, the Inspection Validation Centre (IVC) has operated as a contractor to Nuclear Electric with special arrangements in place to guarantee independence. The setting-up and early methods of operation of IVC are briefly reviewed, the most recent operational experience summarized and the technical significance of the validations to date discussed.

    Hybrid tense logic is an extension of Priorean tense logic in which it is possible to refer to times using special propositional sym- bols called nominals. Temporal indexicals are expressions such as now, yesterday, today, tomorrow and four days ago that have highly context- dependent...... interpretations. Moreover, such indexicals give rise to a special kind of validity—contextual validity—that interacts with ordinary logi- cal validity in interesting and often unexpected ways. In this paper we model these interactions by combining standard techniques from hybrid logic with insights from the work...... of Hans Kamp and David Kaplan. We introduce a simple proof rule, which we call the Kamp Rule, and first we show that it is all we need to take us from logical validities involving now to contextual validities involving now too.

    As the Chinese economy has become an integral part of the global supply chain, quantifying the environmental impacts by Chinese industry is indispensible to understanding the environmental performance of products in general. Comprehensive and consistent environmental data infrastructure, however, is lacking in China, hindering such an understanding. In this paper, we demonstrate a simplified method for assembling and harmonizing various data sources to develop a sectoral environmental database for input-output life cycle assessment (IO-LCA). We first identified key substances by analyzing previous normalization studies and other countries' sectoral environmental databases. Data for priority substances were compiled and then adjusted and validated. The database created from this process was then used to analyze the direct and indirect environmental impacts generated by Chinese rural and urban consumptions. Expenditures on food and other basic household needs like heating and cooking were found to play a dominant role in generating environmental impacts in China, while previous studies of industrialized countries also highlighted the importance of transportation. This database provides background information for LCA through, for example, the hybrid approach, and is also conducive to ongoing efforts to develop generic life cycle inventory databases in China.

    The South China Sea is poorly understood in terms of its marine biota, ecology and the human impacts upon it. What is known is most often contained in reports and workshop and conference documents that are not available to the wider scientific community. The South China Sea has an area of some 3.3 million km2 and depths range from the shallowest coastal fringe to 5377 m in the Manila Trench. It is also studded with numerous islets, atolls and reefs many of which are just awash at low tide.

    The South China Sea is poorly understood in terms of its marine biota, ecology and the human impacts upon it. What is known is most often contained in reports and workshops and conference documents that are not available to the wider scientific community. The South China Sea has an area of some 3.3 million km{sup 2} and depths range from the shallowest coastal fringe to 5377m in the Manila Trench. It is also studded with numerous islets, atolls and reefs many of which are just awash at low tide.

    Results of population programs started in China during the last decade have attracted worldwide attention. The Chinese population issues are important due to the following characteristics: 1) China is the most populated country in the world, with over 1 billion people (22% of world population), by the end of 1980; 2) its population is 80% rural; 3) despite improved living conditions that have helped lower the mortality rate from over 20/1000 before Liberation to 10/1000 in the 1960s and finally 6-8/1000 during the last decade, the Chinese population has increased from 540 million soon after Liberation to the current 1 billion, with an average yearly growth rate of 2%; 4) China has a young population, with 36.8% under 14 years old and less than 5% over 65, hence education and employment are big issues; and 5) due to longterm backward economy resulting from feudal and colonial influence before Liberation, efforts in developing a strong Chinese economy have met with many obstacles. The above 5 features of the Chinese population have important bearing on solving China's population problems and in building its economy, developing its society, and realizing its 4 modernizations. Although China is self-sufficient despite its large population, it faces many problems and challenges especially in the areas of educating its young population and subsequent employment. To achieve a strong economy and to improve the welfare of its people, China has put efforts into controlling the size and improving the quality of its population during the past decade. Programs in population control will continue to take priority in China. PMID:12338284

    The Energy Analysis Program (EAP) at the Lawrence Berkeley Laboratory (LBL) first became involved in Chinese energy issues through a joint China-US symposium on markets and demand for energy held in Nanjing in November of 1988. Discovering common interests, EAP began to collaborate on projects with the Energy Research Institute (ERI) of China's State Planning Commission. In the course of this work it became clear that a major issue in the furtherance of our research was the acquisition of reliable data. In addition to other, more focused activities-evaluating programs of energy conservation undertaken in China and the prospects for making Chinese industrics morc energy-efficient, preparing historical reviews of cncrgy supply and demand in the People's Republic of China, sponsoring researchers from China to work with experts at LBL on such topics as energy efficiency standards for buildings, adaptation of US energy analysis software to Chinese conditions, and transportation issues-we decided to compile, assess, and organize Chinese energy data. Preparing this volume confronted us with a number of difficult issues. The most frustrating usually involved the different approaches to sectoral divisions taken in China and the US. For instance, fuel used by motor vehicles belonging to industrial enterprises is counted as industrial consumption in China; only fuel use by vehicles belonging to enterprises engaged primarily in transportation is countcd as transportation use. The estimated adjustment to count all fuel use by vehicles as transportation energy use is quite large, since a large fraction of motor vehicles belong to industrial enterprises. Similarly, Chinese industrial investment figures are skewed compared to those collected in the US because a large portion of enterprises' investment funds is directed towards providing housing and social services for workers and their families.

    As a naturally part of information technology, Remote Sensing (RS) is strongly required to provide very precise and accurate information product to serve industry, academy and the public at this information economic era. To meet the needs of high quality RS product, building a fully functional and advanced calibration system, including measuring instruments, measuring approaches and target site become extremely important. Supported by MOST of China via national plan, great progress has been made to construct a comprehensive calibration and validation (Cal&Val) site, which integrates most functions of RS sensor aviation testing, EO satellite on-orbit caration and performance assessment and RS product validation at this site located in Baotou, 600km west of Beijing. The site is equipped with various artificial standard targets, including portable and permanent targets, which supports for long-term calibration and validation. A number of fine-designed ground measuring instruments and airborne standard sensors are developed for realizing high-accuracy stepwise validation, an approach in avoiding or reducing uncertainties caused from nonsynchronized measurement. As part of contribution to worldwide Cal&Val study coordinated by CEOS-WGCV, Baotou site is offering its support to Radiometric Calibration Network of Automated Instruments (RadCalNet), with an aim of providing demonstrated global standard automated radiometric calibration service in cooperation with ESA, NASA, CNES and NPL. Furthermore, several Cal&Val campaigns have been performed during the past years to calibrate and validate the spaceborne/airborne optical and SAR sensors, and the results of some typical demonstration are discussed in this study.

    Multiple-choice questions have long been widely used inlarge-scale language proficiency tests in China. Nowadays withthe dramatic increase in the number of test takers, the validityof this type of test is of much concern to various parties. Drawing upon the psycholinguistic theories, the author ofthis article recommends exploring the hidden process the test-takers go through in order to examine its validity. Takingmultiple-choice reading comprehension as an example, theauthor investigates the strategies the test takers employ intackling multiple-choice questions, thereby gaining insights intothe validity of the test type discussed. Such inquiry into test validity not only helps test-developersin their own validation of items, but also helps languageteachers and students in developing a positive attitude towardstests.

    Full Text Available The article presents a review of the English language publications concerning the history and the current state of differential psychological assessment of validity of testimonies produced by child and adolescent victims of crimes. The topicality of the problem in Russia is high due to the tendency of Russian specialists to use methodical means and instruments developed abroad in this sphere for forensic assessments of witness testimony veracity. A system of Statement Validity Analysis (SVA by means of Criteria-Based Content Analysis (CBCA and Validity Checklist is described. The results of laboratory and field studies of validity of CBCA criteria on the basis of child and adult witnesses are discussed. The data display a good differentiating capacity of the method, however, a high level of error probability. The researchers recommend implementation of SVA in the criminal investigation process, but not in the forensic assessment. New perspective developments in the field of methods for differentiation of witness statements based on the real experience and fictional are noted. The conclusion is drawn that empirical studies and a special work for adaptation and development of new approaches should precede their implementation into Russian criminal investigation and forensic assessment practice

    Generally accepted standards for testing and validating ecosystem models would benefit both modellers and model users. Universally applicable test procedures are difficult to prescribe, given the diversity of modelling approaches and the many uses for models. However, the generally accepted scientific principles of documentation and disclosure provide a useful framework for devising general standards for model evaluation. Adequately documenting model tests requires explicit performance criteria, and explicit benchmarks against which model performance is compared. A model's validity, reliability, and accuracy can be most meaningfully judged by explicit comparison against the available alternatives. In contrast, current practice is often characterized by vague, subjective claims that model predictions show 'acceptable' agreement with data; such claims provide little basis for choosing among alternative models. Strict model tests (those that invalid models are unlikely to pass) are the only ones capable of convincing rational skeptics that a model is probably valid. However, 'false positive' rates as low as 10% can substantially erode the power of validation tests, making them insufficiently strict to convince rational skeptics. Validation tests are often undermined by excessive parameter calibration and overuse of ad hoc model features. Tests are often also divorced from the conditions under which a model will be used, particularly when it is designed to forecast beyond the range of historical experience. In such situations, data from laboratory and field manipulation experiments can provide particularly effective tests, because one can create experimental conditions quite different from historical data, and because experimental data can provide a more precisely defined 'target' for the model to hit. We present a simple demonstration showing that the two most common methods for comparing model predictions to environmental time series (plotting model time series

  16. Pension Reform in China.

    Science.gov (United States)

    Liu, Tao; Sun, Li

    2016-01-01

    This article analyzes China's pension arrangement and notes that China has recently established a universal non-contributory pension plan covering urban non-employed workers and all rural residents, combined with the pension plan covering urban employees already in place. Further, in the latest reform, China has discontinued the special pension plan for civil servants and integrated this privileged welfare class into the urban old-age pension insurance program. With these steps, China has achieved a degree of universalism and integration of its pension arrangement unprecedented in the non-Western world. Despite this radical pension transformation strategy, we argue that the current Chinese pension arrangement represents a case of "incomplete" universalism. First, its benefit level is low. Moreover, the benefit level varies from region to region. Finally, universalism in rural China has been undermined due to the existence of the "policy bundle." Additionally, we argue that the 2015 pension reform has created a situation in which the stratification of Chinese pension arrangements has been "flattened," even though it remains stratified to some extent.

    Over the past 50 years, with the improvement of relationship between India and China, the scope of India studies in China's IR research has been broadened and the new areas of studies are being explored. The research agenda of India studies has already extended to the areas like economy, society, culture, security, national strategy and their impact on both bilateral and international relations. In this situation, the focuses of India studies in China's IR research can be mainly identified as follows: reviews on India's social, political and economic systems; analysis on the national strategy and foreign policy; Sino-Indian relations; India's relations with some international organizations. However, even though many fresh progresses have been made in India studies, the India studies in China's IR research still lag far behind the study of other important countries like the U.S., UK, Russia and Japan, and more problems and challenges will face in the coming future. The paper believes that a fuller understanding of India probably will not make China and India close friends, but it definitely will help to prevent them from becoming fierce enemies.

    Palaeogeography is a science that studies the features and evolution of physical geography in geological history and human history. The palaeogeography of China has multiple disciplines and multiple types of palaeogeographic map. These perfectly reflect "a hundred flowers blossom and a hundred schools of thought content". The palaeogeography of China has three characteristics. The first is multiple disciplines flourishing simultaneously. The second is that lithofacies palaeogeography is in a leading position. The third is that palaeogeography of China is closely connected with industrial practice. It is why palaeogeography, especially lithofacies palaeogeography of China, can flourish continually. We have two journals of palaeogeography, i. e. Journal of Palaeogeography (Chinese Edition) and Journal of Palaeogeography (English Edition). The former primarily publishes articles of Chinese authors regarding Chinese palaeogeography and related disciplines and has a foothold in China. The latter will publish the articles of both Chinese and international authors and caters to foreign readers. These two journals will cooperate together and display their own expertise, which will effectively make a great contribution to the development and innovation of Chinese palaeogeography and international palaeogeography.

    Full Text Available In the business process world, web services present a managed and middleware to connect huge number of services. Web service transaction is a mechanism to compose services with their desired quality parameters. If enormous transactions occur, the provider could not acquire the accurate data at the correct time. So it is necessary to reduce the overburden of web service t ransactions. In order to reduce the excess of transactions form customers to providers, this paper propose a new method called Equalization Validation Classification. This method introduces a new weight - reducing algorithm called Efficient Trim Down algorit hm to reduce the overburden of the incoming client requests. When this proposed algorithm is compared with Decision tree algorithms of (J48, Random Tree, Random Forest, AD Tree it produces a better accuracy and Validation than the existing algorithms. The proposed trimming method was analyzed with the Decision tree algorithms and the results implementation shows that the ETD algorithm provides better performance in terms of improved accuracy with Effective Validation. Therefore, the proposed method provide s a good gateway to reduce the overburden of the client requests in web services. Moreover analyzing the requests arrived from a vast number of clients and preventing the illegitimate requests save the service provider time

  19. Bringing Biocuration to China

    Biocuration involves adding value to biomedical data by the processes of standardiza-tion, quality control and information transferring (also known as data annotation). It enhances data interoperability and consistency, and is critical in translating biomedical data into scientific discovery. Although China is becoming a leading scientific data producer, biocuration is still very new to the Chinese biomedical data community. In fact, there currently lacks an equivalent acknowledged word in Chinese for the word ‘‘curation”. Here we propose its Chinese translation as‘‘审编”(Pinyin:shen bian), based on its implied meanings taken by biomedical data community. The 8th International Biocuration Conference to be held in China (http://biocuration2015.tilsi.org) next year bears the potential to raise the general awareness in China of the significant role of biocuration in scientific discovery. However, challenges are ahead in its implementation.

    It is clear from the trade press that American, European, and Japanese chemical companies are making major capital investment commitments in China. They are also developing strategies to participate in the country's growth. Many people wonder how long the window of opportunity will remain open. Some questions one may ask include: What are the driving forces for such intense activity? What role is the Chinese government playing in implementing growth plans? What are the classes of chemical products receiving priority attention? To what degree is China integrating upstream into energy and basic feedstocks? What are the long-term implications for Asia and the rest of the world with respect to foreign trade? To answer these and other questions, Martech, Inc., a subsidiary of Mitsubishi Chemical Corporation, recently completed a comprehensive report on China's petrochemical industry.

This false-color image of the western Yangtze River and Dongting Lake in central China was acquired on August 21, 2002, by the Moderate-resolution Imaging Spectroradiometer (MODIS), flying aboard NASA's Terra spacecraft. (right) The latest flooding crisis in China centers on Dingtong Lake in the center of the image. Heavy rains have caused it to swell over its banks and swamp lakefront towns in the province of Hunan. As of August 23, 2002, more than 250,000 people have been evacuated, and over one million people have been brought in to fortify the dikes around the lake. Normally the lake would appear much smaller and more defined in the MODIS image. Credit: Image courtesy Jacques Descloitres, MODIS Land Rapid Response Team at NASA GSFC.

  17. JaqEngine Model Validation

    Energy Technology Data Exchange (ETDEWEB)

    Rademakers, C.

    2009-03-15

    The JaqEngine is a concept engine. It runs on the two stroke internal combustion principle, but is based on an uncommon piston setup and a unique mechanical conversion system. The design of the current prototype of the JaqEngine is (partially) based on two thermodynamic models: A numeric combustion cycle (NCC) model and a computational fluid dynamics (CFD) model. The NCC model simulates multiple combustion cycles and determines global parameters such as cylinder pressure, engine power and overall efficiency. The CFD model simulates the turbulent flow of gasses running through the engine. It provides more detailed information at the cost of increased computational demands. Changes made to the design of the JaqEngine are based on the results of these thermodynamic models. To ensure their results are accurate and reliable, the models need to be validated. Validation consists of checking the input, the used modelling density (e.g. step size or grid size), the working principles of the various components and the implementation of the underlying physical phenomena. After the models are functionally validated they can be verified and corrected using real life data. Eventually the thermodynamics models are a valuable component during redesigning prototypes and programming the engine management system. This report covers the validation of both thermodynamic models of the JaqEngine. The characteristics of the JaqEngine, its benefits and its disadvantages are summed up, with special attention to the usability of the thermodynamic models. The NCC model is rewritten into a more practical format and each component is individually analyzed and checked. The stability and grid quality of the CFD model are investigated and the solver is validated using a backward facing step. Also the usability of the CFD model is investigated by analyzing the performance of the ports and manifolds. In the final part of the report the requirements and setup of the engine test bed is given along with

    1984-01-01

    The validity of the stratospheric aerosol measurements made by the satellite sensors SAM II and SAGE was tested by comparing their results with each other and with results obtained by other techniques (lider, dustsonde, filter, and impactor). The latter type of comparison required the development of special techniques that convert the quantity measured by the correlative sensor (e.g. particle backscatter, number, or mass) to that measured by the satellite sensor (extinction) and quantitatively estimate the uncertainty in the conversion process. The results of both types of comparisons show agreement within the measurement and conversion uncertainties. Moreover, the satellite uncertainty is small compared to aerosol natural variability (caused by seasonal changes, volcanoes, sudden warmings, and vortex structure). It was concluded that the satellite measurements are valid.

    2010-01-01

    Full Text Available The semivariogram function fitting is the most important aspect of geostatistics and because of this the model chosen must be validated. Jack knifing may be one the most efficient ways for this validation purpose. The objective of this study was to show the use of the jack knifing technique to validate geostatistical hypothesis and semivariogram models. For that purpose, topographical heights data obtained from six distinct field scales and sampling densities were analyzed. Because the topographical data showed very strong trend for all fields as it was verified by the absence of a sill in the experimental semivariograms, the trend was removed with a trend surface fitted by minimum square deviation. Semivariogram models were fitted with different techniques and the results of the jack knifing with them were compared. The jack knifing parameters analyzed were the intercept, slope and correlation coefficient between measured and estimated values, and the mean and variance of the errors calculated by the difference between measured and estimated values, divided by the square root of the estimation variances. The ideal numbers of neighbors used in each estimation was also studied using the jack knifing procedure. The jack knifing results were useful in the judgment of the adequate models fitted independent of the scale and sampling densities. It was concluded that the manual fitted semivariogram models produced better jack knifing parameters because the user has the freedom to choose a better fit in distinct regions of the semivariogram.

    Objective:To evaluate the technical characteristics and application of mass casualty incident (MCI) primary triage (PT) methods applied in China.Data Sources:Chinese literature was searched by Chinese Academic Journal Network Publishing Database (founded in June 2014).The English literature was searched by PubMed (MEDLINE) (1950 to June 2014).We also searched Official Websites of Chinese Central Government's (http://www.gov.cn/),National Health and Family Planning Commission of China (http://www.nhfpc.gov.cn/),and China Earthquake Information (http://www.csi.ac.cn/).Study Selection:We included studies associated with mass casualty events related to China,the PT applied in China,guidelines and standards,and application and development of the carding PT method in China.Results:From 3976 potentially relevant articles,22 met the inclusion criteria,20 Chinese,and 2 English.These articles included 13 case reports,3 retrospective analyses of MCI,two methods introductions,three national or sectoral criteria,and one simulated field testing and validation.There were a total of 19 kinds ofMCI PT methods that have been reported in China from 1950 to 2014.In addition,there were 15 kinds of PT methods reported in the literature from the instance of the application.Conclusions:The national and sectoral current triage criteria are developed mainly for earthquake relief.Classification is not clear.Vague criteria (especially between moderate and severe injuries) operability are not practical.There are no triage methods and research for children and special populations.There is no data and evidence supported triage method.We should revise our existing classification and criteria so it is clearer and easier to be grasped in order to build a real,practical,and efficient PT method.

This paper, based on the development track of cities at home and abroad, puts forward the new research perspective judgment. There is the Logistic curve between economic development and urban sprawl, and then the authors select the typical cities in East China for empirical test. As the results show: First, economic growth' dependence on urban sprawl weakened gradually abroad from the rapid ur- banization, industrialization primary phase transiting to the senior or after the process of industriali- zation stage. Second, China's economic growth and urban sprawl has periodical fluctuating charac- teristics from 1978 to 2003, and there have been significant decoupling or different fluctuations since 2003. Third, the empirical results show that turning points would come in urban

    The Soil Moisture Active Passive (SMAP) mission launched on Jan 31, 2015. The mission employs L-band radar and radiometer measurements to estimate soil moisture with 4% volumetric accuracy at a resolution of 10 km, and freeze-thaw state at a resolution of 1-3 km. Immediately following launch, there was a three month instrument checkout period, followed by six months of level 1 (L1) calibration and validation. In this presentation, we will discuss the calibration and validation activities and results for the L1 radar data. Early SMAP radar data were used to check commanded timing parameters, and to work out issues in the low- and high-resolution radar processors. From April 3-13 the radar collected receive only mode data to conduct a survey of RFI sources. Analysis of the RFI environment led to a preferred operating frequency. The RFI survey data were also used to validate noise subtraction and scaling operations in the radar processors. Normal radar operations resumed on April 13. All radar data were examined closely for image quality and calibration issues which led to improvements in the radar data products for the beta release at the end of July. Radar data were used to determine and correct for small biases in the reported spacecraft attitude. Geo-location was validated against coastline positions and the known positions of corner reflectors. Residual errors at the time of the beta release are about 350 m. Intra-swath biases in the high-resolution backscatter images are reduced to less than 0.3 dB for all polarizations. Radiometric cross-calibration with Aquarius was performed using areas of the Amazon rain forest. Cross-calibration was also examined using ocean data from the low-resolution processor and comparing with the Aquarius wind model function. Using all a-priori calibration constants provided good results with co-polarized measurements matching to better than 1 dB, and cross-polarized measurements matching to about 1 dB in the beta release.

    Full Text Available In the software measurement validations, assessing the validation of software metrics in software engineering is a very difficult task due to lack of theoretical methodology and empirical methodology [41, 44, 45]. During recent years, there have been a number of researchers addressing the issue of validating software metrics. At present, software metrics are validated theoretically using properties of measures. Further, software measurement plays an important role in understanding and controlling software development practices and products. The major requirement in software measurement is that the measures must represent accurately those attributes they purport to quantify and validation is critical to the success of software measurement. Normally, validation is a collection of analysis and testing activities across the full life cycle and complements the efforts of other quality engineering functions and validation is a critical task in any engineering project. Further, validation objective is to discover defects in a system and assess whether or not the system is useful and usable in operational situation. In the case of software engineering, validation is one of the software engineering disciplines that help build quality into software. The major objective of software validation process is to determine that the software performs its intended functions correctly and provides information about its quality and reliability. This paper discusses the validation methodology, techniques and different properties of measures that are used for software metrics validation. In most cases, theoretical and empirical validations are conducted for software metrics validations in software engineering [1-50].

  5. Why is China going nuclear?

    International Nuclear Information System (INIS)

    In November 2007, China's State Council approved its 'Medium- and Long-Term Nuclear Power Development Plan', which set as a goal to increase the nation's nuclear capacity from about 7 to 40 GWe by 2020. In March 2008, the National Development and Reform Commission suggested installed nuclear power capacity might even exceed 60 GWe by 2020 due to faster than expected construction. Even with this growth, nuclear power's share of China's installed total capacity would be only about 5 percent. Yet China's rapid nuclear expansion poses serious financial, political, security, and environmental challenges. This study investigates China's claim that nuclear energy is necessary to meet its growing energy demands by analyzing China's energy alternatives and assessing their likelihood of contributing to total Chinese capacity. By looking at China's transformative energy policy from several perspectives, this study finds that nuclear energy is indeed a necessity for China.

  5. China's petroleum reserves

    Science.gov (United States)

    Bell, Peter M.

    Perhaps because of declining yields inland, the People's Republic of China has moved to its storm-ridden coast to develop additional petroleum reserves. During 1979 and 1980, 44 foreign oil-exploration companies engaged in what has been termed the world's record “seismic shoot” over 411,000 km2 extending from the Yellow Sea through the South China Sea, and including Beibu Wan (Gulf of Tonkin), the bay lying east of Hanoi and west of Hainan Island. These offshore oil reserves are estimated to be 40-100 billion barrels.The seas off the mainland are relatively shallow (most drilling has been done in less than 100 m) but they are stormy. According to a recent description, “Typhoons can … occur in the area at almost any time of the year, and the strong winds (160 km h-1 or more) which they generate frequently wreak havoc in the Philippines, Vietnam, China, and occasionally, Hong Kong. Typhoon Vera, which hit southern China in late July, did immense damage and claimed dozens of lives. The main implications for oil operation naturally relate to rig design and safety measures but onshore facilities will also have to be designed accordingly” (New Scientist, Sept. 8, 1983).

    Three uranium provinces are recognized in China, the Southeast China uranium province, the Northeast China-lnner Mongolia uranium province and the Northwest China (Xinjiang) uranium province. The latter two promise good potential for uranium resources and are major exploration target areas in recent years. There are two major types of uranium deposits: the Phanerozoic hydrothermal type (vein type) and the Meso-Cenozoic sandstone type in different proportions in the three uranium provinces. The most important reason or prerequisite for the formation of these uranium provinces is that Precambrian uranium-enriched old basement or its broken parts (median massifs) exists or once existed in these regions, and underwent strong tectonomagmatic activation during Phanerozoic time. Uranium was mobilized from the old basement and migrated upwards to the upper structural level together with the acidic magma originating from anatexis and the primary fluids, which were then mixed with meteoric water and resulted in the formation of Phanerozoic hydrothermal uranium deposits under extensional tectonic environments. Erosion of uraniferous rocks and pre-existing uranium deposits during the Meso-Cenozoic brought about the removal of uranium into young sedimentary basins. When those basins were uplifted and slightly deformed by later tectonic activity, roll-type uranium deposits were formed as a result of redox in permeable sandstone strata.

It has been a natural counterpart to the Energy Analysis Program`s continuing program of collaborative research with the Energy Research Institute. No other current reference volume dedicated to China`s energy system contains a similar variety and quality of material. We have revised some of the categories and data that appeared in the old volume. The adjustment for energy consumption in the transportation sector, for instance, has been slightly changed to include some fuel use in the commercial sector, which was previously left out. As another example, natural gas consumption statistics in the first edition greatly overstated electric utility use; we have rectified that error. Some tables have changed as statistical collection and reporting practices change in China. Figures on gross output value by sector stop with 1992, and economic output in subsequent years is covered by various measures of value-added, such as national income and gross domestic product.

    The work of radiation protection has been given great attention in China. The Ministry of Health is the competent authority in charge of the work. Before the accident at Chernobyl, the government had formulated and promulgated laws and regulations concerning the radiation protection, such as the Basic Standard for Radiation Protection, the Basic Standard for Radiation Protection of Nuclear Plants, the institutions and organizations for monitoring radioactive pollution at national level and provincial level had been set up. After the accident at Chernobyl, each of the monitoring institutions and organizations took samples of air, subsided substances of atmosphere, rainwater, terrestrial surface water from various sources, vegetables, milk and thyroid glands of sheep and goats immediately, for the detection of radiation contamination. As far as we know that the samples had small extent contamination, the extent of contamination of samples in the south of China is smaller than that of samples in the north of China, that the content of nuclides in various samples is lower than the limits of radioactive substances set in national standard, and that radiation dosage subjected by residents of China caused by the contamination is also lower than the set quota in the national standard. The contamination did not interfere with the regular life of the residents

Three samples of full-time employees (Ns = 205, 266, and 283) from different companies and industries participated in the present study. Confirmatory factor analysis showed that a single-factor structure fit the data. The scale had acceptable reliabilities, convergent and criterion-related validities, and was shown to be an appropriate measure of psychological work maturity in Chinese employees. Maturity differences in several demographic variables were not found, but employees with longer tenure in Sample 2 scored higher on maturity, which shows that psychological work maturity may be dependent on personal development in the interaction with the varying situational factors, especially in the work domain. Implications for research and practice on psychological work maturity in China are discussed.

    The IP packet forwarding of current Internet is mainly destination based. In the forwarding process, the source IP address is not checked in most cases.This causes serious security, management and accounting problems. Based on the drastically increased IPv6 address space, a "source address validation architecture" (SAVA) is proposed in this paper, which can guarantee that every packet received and forwarded holds an authenticated source IP address. The design goals of the architecture are lightweight, loose coupling, "multi-fence support" and incremental deployment. This paper discusses the design and implementation for the architecture, including inter-AS, intra-AS and local subnet. The performance and scalability of SAVA are described. This architecture is deployed into the CNGI-CERNET2infrastructure--a large-scale native IPv6 backbone network of the China Next Generation Internet project. We believe that the SAVA will help the transition to a new, more secure and dependable Internet.

    Cancer remains to be the second most common cause of death, and its incidence and mortality rates are increasing in China. According to the 2015 National Central Cancer Registry (NCCR) of China, the incidence of bladder cancer and prostate cancer ranked sixth and seventh, respectively, in male cancers. The majority of prostate cancer patients were diagnosed at an advanced stage. Early diagnosis of prostate cancer is the key to improve prostate cancer survival in China. Radical prostatectomy or radical radiotherapy is the main treatment for localized prostate cancer, and a comprehensive therapy based on androgen deprivation therapy is the treatment for advanced disease. The most common histologic types of bladder cancer in China were urothelial carcinoma, followed by adenocarcinoma and squamous carcinoma. The majority of patients were diagnosed using white-light cystoscopy with biopsy. Fluorescence and narrow-band imaging cystoscopy had additional detection rates and are becoming more popular. Following Chinese guidelines, most non-muscle invasive bladder cancer patients were treated with diagnostic transurethral resection and more than half of the muscle invasive bladder cancer patients were treated with radical cystectomy. Due to the increased detection rate of kidney tumors by ultrasound in physical examination, the number of incidentally diagnosed renal cell carcinoma has increased. Localized kidney cancers are more and more often treated by nephron-sparing surgery. Radical nephrectomy is still the main treatment option for patients with locally advanced renal cell carcinoma. Both laparoscopic and robotic-assisted laparoscopic surgeries have been used in big medical centers. Both testicular cancer and penile cancer have lower incidence levels than that in Europe. As we have an enormous population base, the absolute patient number is big. The diagnosis and treatment follows the Chinese guidelines. In China, both medical professionals and public should concern

    The Energy Analysis Program at the Lawrence Berkeley Laboratory (LBL) first became involved in Chinese energy issues through a joint China-US symposium on markets and demand for energy held in Nanjing in November of 1988. Discovering common interests, EAP began to collaborate on projects with the Energy Research Institute of China's State Planning Commission. In the course of this work it became clear that a major issue in the furtherance of our research was the acquisition of reliable data. In addition to other, more focused activities-evaluating programs of energy conservation undertaken in China and the prospects for making Chinese industries more energy-efficient, preparing historical reviews of energy supply and demand in the People's Republic of China, sponsoring researchers from China to work with experts at LBL on such topics as energy efficiency standards for buildings, adaptation of US energy analysis software to Chinese conditions, and transportation issues, we decided to compile, assess, and organize Chinese energy data. We are hopeful that this volume will not only help us in our work, but help build a broader community of Chinese energy policy studies within the US. In order to select appropriate data from what was available we established several criteria. Our primary interest was to use the data to help understand the historical evolution and likely future of the Chinese energy system. A primary criterion was thus that the data relate to the structure of energy supply and demand in the past and indicate probable developments (e.g., as indicated by patterns of investment). Other standards were accuracy, consistency with other information, and completeness of coverage. This is not to say that all the data presented herein are accurate, consistent, and complete, but where discrepancies and omissions do occur we have tried to note them

As one project of the National Basic Research Programme of China (973 Programme) in energy domain, which is sponsored by the China Ministry of Science and Technology (MOST), a five year programme of fundamental research of ADS physics and related technology was launched in 2000 and passed national review at the end of 2005. From 2007, another five year 973 Programme Key Technology Research of Accelerator Driven Subcritical System for Nuclear waste Transmutation started. The research activities were focused on HPPA physics and technology, reactor physics of external source driven subcritical assembly, nuclear data base and material study. For HPPA, a high current injector consisting of an ECR ion source, LEBT and an RFQ accelerating structure of 3.5 MeV has been built and were being improved. In reactor physics study, a series of neutron multiplication experimental study has been carrying out. The VENUS I facility has been constructed as the basic experimental platform for neutronics study in ADS blanket. VENUS I a zero power subcritical neutron multiplying assembly driven by external neutron produced by a pulsed neutron generator or 252Cf neutron source. The theoretical, experimental and simulation studies on nuclear data, material properties and nuclear fuel circulation related to ADS are carried out in order to provide the database for ADS system analysis. China Institute of Atomic Energy (CIAE), Institute of High Energy Physics (IHEP) and other Chinese institutes carried out the MOST project together. Besides CIAE, China Academy of Science (CAS) pays more and more attention to Advanced Nuclear Fuel Cycles (ANFC).

    This paper presents results of measurements of tropospheric sulphur dioxide (SO2) from satellite over China during 2004-2009. SCIAMACHY/ENVISAT SO2 data products have been validated by ground based remote sensing instrument MAXDOAS in China, and with predictions of the atmospheric model GEOS-Chem. The spatial and temporal distribution of tropospheric SO2 over China is discussed in this study. The result shows that the SO2 load over East China is decreasing since strong control for pollution emission in 2007 for preparation of 2008 Olympic Games in China, while the SO2 load in West China is increasing all the way during 2004-2009, which might reflect that the anthropogenic activity was added to promote the economy development in west of China. Typical seasonal variation with high pollution levels in winter and low in summer is found in the northwest of China, while the inverse seasonal variation is found for the south of China. The characteristics of tropospheric SO2 over the major cities in China were explored and found that tropospheric SO2 was partly under control from 2007 because of the policy from China government for reduction in SO2 emissions in 2006. And the SO2 value shows remarkably decrease in most of the major cities after 2007 because strong control for the pollution emission for 2008 Olympic games. Guangzhou city shows high SO2 pollution levels in summer time, since most of the coal power plants and thermal power industry are located to the south of Guangzhou city and southerly winds dominate during summer time.

  4. Turbulence Modeling Verification and Validation

    2014-01-01

    Computational fluid dynamics (CFD) software that solves the Reynolds-averaged Navier-Stokes (RANS) equations has been in routine use for more than a quarter of a century. It is currently employed not only for basic research in fluid dynamics, but also for the analysis and design processes in many industries worldwide, including aerospace, automotive, power generation, chemical manufacturing, polymer processing, and petroleum exploration. A key feature of RANS CFD is the turbulence model. Because the RANS equations are unclosed, a model is necessary to describe the effects of the turbulence on the mean flow, through the Reynolds stress terms. The turbulence model is one of the largest sources of uncertainty in RANS CFD, and most models are known to be flawed in one way or another. Alternative methods such as direct numerical simulations (DNS) and large eddy simulations (LES) rely less on modeling and hence include more physics than RANS. In DNS all turbulent scales are resolved, and in LES the large scales are resolved and the effects of the smallest turbulence scales are modeled. However, both DNS and LES are too expensive for most routine industrial usage on today's computers. Hybrid RANS-LES, which blends RANS near walls with LES away from walls, helps to moderate the cost while still retaining some of the scale-resolving capability of LES, but for some applications it can still be too expensive. Even considering its associated uncertainties, RANS turbulence modeling has proved to be very useful for a wide variety of applications. For example, in the aerospace field, many RANS models are considered to be reliable for computing attached flows. However, existing turbulence models are known to be inaccurate for many flows involving separation. Research has been ongoing for decades in an attempt to improve turbulence models for separated and other nonequilibrium flows. When developing or improving turbulence models, both verification and validation are important

    Since China adopted an open door policy in 1978, its economy has grown rapidly. Between 1980 and 1993, China`s real GNP growth averaged 9.4 percent per year. Economists at the Chinese Academy of Social Sciences forecast that GNP will increase by 11.5 percent in 1994. During the rest of the decade, the Chinese government plans to reduce its annual GNP growth rate to 8-9 percent. During the 2001-2010 period, the economic growth rate is projected to decline to 6.5 percent per year. Table 1 compares China`s economic growth to other Asia-Pacific Economies, and includes projections to 2010. During the 1980s, China`s GDP growth rate was only second to that of South Korea. In the 1990`s, China is projected to have the highest economic growth in the Asia-Pacific region. China`s rapid economic growth is due to dramatic increases in the effective labor supply and effective capital stock. For the remainder of the 1990s, the effective labor supply should continue to increase rapidly because: (1) Chinese state enterprises are over-staffed and labor system reforms will move millions of these workers into more productive activities; (2) reforms in the wage system will provide increased incentives to work harder; (3) relaxation of migration controls from rural to urban areas will cause nominal labor in the industrial sector to accelerate; (4) differentials in personal income will increase and develop peer pressure on workers to work harder and earn more money; and (5) at China`s low personal income level, Chinese people are willing to trade leisure for more income as wages increase.

    Full Text Available Rather than China versus Islam, the overarching theme of this special issue is “Islam in China/China in Islam.” In thinking through “Islam in China,” we argue that the relationship between China and Islam is not one of opposition, but rather one of cultural, linguistic, and economic imbrication. Indeed, it is difficult to describe Islam and China as two separate or essentialized entities. For some Muslim minorities in certain regions of China, there is no distinction between neo-Confucianism and Islam or between the nation-state and the global umma (community of Muslims. Through intellectual labor, modes of prayer and worship, art, calligraphy, architecture, cuisine, linguistic creoles, and legal pluralism, these Muslims embody multiple cultural referents. For other Muslim minorities in other regions in China, political and economic circumstances present challenges to living in accordance with Islam while also being a citizen of the PRC. In other words, the Muslim experience in China encompasses a complex mosaic of accommodation, adjustment, preservation, and, at times, resistance. Thus, generalizations about this incredibly diverse population are unhelpful, and careful attention must be paid to history, politics, and place...

    Chinese inflation, particularly non-food inflation, has been surprisingly modest in recent years. We find that supply factors, including those captured through upstream foreign commodity and producer prices, have been important drivers of non-food inflation, as has foreign demand for Chinese goods. Domestic demand and monetary conditions seem less important, possibly reflecting a large domestic output gap generated by many years of high investment. Inflation varies systemically within China, ...

  19. Convergent Validity of the PUTS

    Full Text Available Premonitory urges are a cardinal feature in Gilles de la Tourette syndrome. Severity of premonitory urges can be assessed with the Premonitory Urge for Tic Disorders Scale (PUTS. However, convergent validity of the measure has been difficult to assess due to the lack of other urge measures.We investigated the relationship between average real-time urge intensity assessed by an in-house developed real-time urge monitor, measuring urge intensity continuously for 5mins on a visual analogue scale, and general urge intensity assessed by the PUTS in 22 adult Tourette patients (mean age 29.8+/- 10.3; 19 male. Additionally, underlying factors of premonitory urges assessed by the PUTS were investigated in the adult sample using factor analysis and were replicated in 40 children and adolescents diagnosed with Tourette syndrome (mean age 12.05 +/- 2.83 SD, 31 male.Cronbach’s alpha for the PUTS10 was acceptable (α = .79 in the adult sample. Convergent validity between average real-time urge intensity scores (as assessed with the real-time urge monitor and the 10-item version of the PUTS (r = .64 and the 9-item version of the PUTS (r = .66 was good. A factor analysis including the 10 items of the PUTS and average real-time urge intensity scores revealed three factors. One factor included the average real-time urge intensity score and appeared to measure urge intensity, while the other two factors can be assumed to reflect the (sensory quality of urges and subjective control, respectively. The factor structure of the 10 PUTS items alone was replicated in a sample of children and adolescents.The results indicate that convergent validity between the PUTS and the real-time urge assessment monitor is good. Furthermore, the results suggest that the PUTS might assess more than one dimension of urges and it may be worthwhile developing different sub-scales of the PUTS assessing premonitory urges in terms of intensity and quality, as well as subjectively

  20. Validation of maritime spectral features

    Science.gov (United States)

    Hubler, Matthew J.

    In 1991 a research team led by Klaus Hasselmann developed a general technique to build synthetic aperture radar (SAR) spectra from scans of the ocean surface; however these techniques were verified on older equipment. The algorithms input a SAR spectrum from an ocean spectrum, an inversion from SAR spectrum to ocean spectrum, and determine the threshold of the azimuthal cutoff. Originally designed for platforms that have since fulfilled their missions, the question remains as to whether the algorithms are valid with newer systems such as TerraSAR-X operated by German Aerospace Centre (DLR). One of the larger differences that may skew data analysis by these algorithms is that TerraSAR-X has much finer resolution, pixels being on the scale of 5--10 meters (or less), while older satellites returned images with pixel scaling on the order of kilometers. The finer pixel scaling allows for more detail to be recovered and analyzed, specifically the individual waves on the ocean surface become visible. To that end, algorithms developed for older satellites will be employed on data collected from TerraSAR-X and compared to ground truth data in order to assess the compatibility of existing algorithms. During the course of the validation, several sets of code, written in Matlab, will be employed and discussed, each providing a different approach, more focused results. In aggregate a clearer picture will emerge describing the accuracy that older algorithms have with newer machinery. The imagery data, being satellite borne, comes with individual collection geometry that needs to be addressed in the processing as well, currently through parsing the accompanying metadata. The determination that these algorithms indeed work with newer systems and the validation of an azimuthal cutoff demonstrate that little fine tuning of older algorithms is needed at these higher resolutions. While the Hasselmann algorithms become cumbersome to use, a new approach to the algorithms yield useful
