Food safety standard draws increasing concerns on agricultural trade throughout the world.This paper aims to assess the impact of maximum residual limit standard(MRL) of chloromycetin on honey exporting from China.To achieve this objective,the paper discusses the trends of China's honey production and export practices,analyzes changes on MRL of chloromycetin adopted by major importing countries,and use a gravity model to estimate the impact of MRL of chloromycetin on China's honey export.The results show that despite the rapid growth of China's honey production,honey export has declined significantly since 2000.The major reason of declining honey export was mainly due to the more stringent food safety standards indicated by MRL of chloromycetin imposed by importing countries on their honey imports. 展开更多

The China Infectious Disease Automated-alert and Response System(CIDARS) was successfully implemented and became operational nationwide in 2008. The CIDARS plays an important role in and has been integrated into the routine outbreak monitoring efforts of the Center for Disease Control(CDC) at all levels in China. In the CIDARS, thresholds are determined using the ?Mean+2SD? in the early stage which have limitations. This study compared the performance of optimized thresholds defined using the ?Mean +2SD? method to the performance of 5 novel algorithms to select optimal ?Outbreak Gold Standard(OGS)? and corresponding thresholds for outbreak detection. Data for infectious disease were organized by calendar week and year. The ?Mean+2 SD?, C1, C2, moving average(MA), seasonal model(SM), and cumulative sum(CUSUM) algorithms were applied. Outbreak signals for the predicted value(Px) were calculated using a percentile-based moving window. When the outbreak signals generated by an algorithm were in line with a Px generated outbreak signal for each week, this Px was then defined as the optimized threshold for that algorithm. In this study, six infectious diseases were selected and classified into TYPE A(chickenpox and mumps), TYPE B(influenza and rubella) and TYPE C [hand foot and mouth disease(HFMD) and scarlet fever]. Optimized thresholds for chickenpox(P_(55)), mumps(P_(50)), influenza(P_(40), P_(55), and P_(75)), rubella(P_(45) and P_(75)), HFMD(P_(65) and P_(70)), and scarlet fever(P_(75) and P_(80)) were identified. The C1, C2, CUSUM, SM, and MA algorithms were appropriate for TYPE A. All 6 algorithms were appropriate for TYPE B. C1 and CUSUM algorithms were appropriate for TYPE C. It is critical to incorporate more flexible algorithms as OGS into the CIDRAS and to identify the proper OGS and corresponding recommended optimized threshold by different infectious disease types. 展开更多

The farming-pastoral ecotone of northern China(FPENC)provides an important ecological barrier which restrains the invasion of desert into Northwest China.Studying drought and flood characteristics in the FPENC can provide scientific support and practical basis for the protection of the FPENC.Based on monthly precipitation data from 115 meteorological stations,we determined the changes in climate and the temporal and spatial variations of drought and flood occurrence in the FPENC during 1960-2020 using the Standardized Precipitation Index(SPI),Morlet wavelet transform,and inverse distance weighted interpolation method.Annual precipitation in the FPENC showed a slightly increasing trend from 1960 to 2020,with an increasing rate of about 1.15 mm/a.The interannual SPI exhibited obvious fluctuations,showing an overall non-significant upward trend(increasing rate of 0.02/a).Therefore,the study area showed a wetting trend in recent years.Drought and flood disasters mainly occurred on an interannual change cycle of 2-6 and 9-17 a,respectively.In the future,a tendency towards drought can be expected in the FPENC.The temporal and spatial distribution of drought and flood differed in the northwestern,northern,and northeastern segments of the FPENC,and most of the drought and flood disasters occurred in local areas.Severe and extreme drought disasters were concentrated in the northwestern and northeastern segments,and severe and extreme flood disasters were mainly in the northeastern segment.Drought was most frequent in the northwestern segment,the central part of the northeastern segment,and the northern part of the northern segment.Flood was most frequent in the western part of the northwestern segment,the eastern part of the northeastern segment,and the eastern and western parts of the northern segment.The accurate evaluation of the degrees of drought and flood disasters in the FPENC will provide scientific basis for the regional climate study and critical information on which to base decisions regarding environmental protection and socio-economic development in this region. 展开更多

Although the story continuation writing task(SCWT) has attracted much research attention, few studies have investigated the construct of the task, particularly with respect to which language competence it focuses on. In addition, although some studies have demonstrated that China’s Standards of English Language Ability(CSE) provides comprehensive insights into the development of Chinese learners’ English language proficiency, little research has investigated the relationship between CSE and SCWT. This study drew upon the CSE to develop an SCWT language use inventory to address the above research gaps. A total of 358 high school students were asked to complete the questionnaire, of which 277 valid responses were analyzed. Exploratory factor analysis(EFA) on the CSE-based questionnaire revealed the presence of six factors, namely language correctness, language variety, task planning, connecting-and-generating, selecting-andmining, and organizing. The strategy of connecting-and-generating was the only significant predictor of the learners’ SCWT scores. The paper also discusses the findings relating to the SCWT rating and other integrated writing tasks. 展开更多

In July 2014,《International Financial Reporting Standard 9:Financial Instruments》(Referred to IFRS 9)was formally published. Compared to the former standard,《International Accounting Standard 39: Financial Instruments》(Referred to IAS 39), rules of two main aspects, the classification and measurement of financial assets and the impairment model of financial assets have been changed in IFRS 9. Taking ICBC as an example, this paper studies the impact of changes in financial instruments on commercial banks. The study shows three impacts on commercial banks’ financial report. Firstly, the changes of the classification and measurement of financial assets will have limited impacts on commercial banks. Secondly, the expected-loss model will significantly increase the loan loss reserves under the new standard, thus reducing the net asset and net profit. Thirdly, the change in the measurement way of the equity instruments of available-for-sale securities will increase the fluctuation of the net profit. This study shows investors and regulators the impact of the new standard of financial instruments on commercial banks. 展开更多

The Rural Minimum Living Standard Guarantee(Rural Dibao)is an important unconditional cash transfer program to alleviate poverty in rural China.Despite the importance of children’s nutrition in breaking poverty cycles,little is known about the impact of Rural Dibao on child nutrition outcomes.Using China Family Panel Studies(CFPS),this paper examines the effects of Rural Dibao on child nutrition outcomes and investigates potential pathways and heterogeneous effects.We exploit propensity score matching and difference-in-differences techniques to evaluate the effects of the Rural Dibao program on child nutrition outcomes.Our results suggest that Rural Dibao significantly impacts the nutrition outcomes of children up to 15 years of age.Specifically,our results suggest that Rural Dibao improves child height-to-age z-scores by 1.05 standard deviations and lowers the probability of stunting by 11.9 percentage points.Additional analyses suggest that increased protein intake is the main pathway through which Rural Dibao participation contributes to better nutrition outcomes.We also find that the effect of the program is more pronounced among girls,children who are non-left-behind or live with highly educated mothers,and those from low-income families and poor areas.Our findings suggest that Rural Dibao participation helps improve child nutrition outcomes through improving diet quality. 展开更多

Numerous studies evaluated the effects of end-of-pipe control environmental regulations(EER).However,few scholars discussed the effects of process management environmental regulations(PER),such as the China Cleaner Production Standards(CCPS)implemented by the country's Ministry of Ecology and Environment.Using data on China's manufacturing enterprises,this paper adopts the CCPS policies as quasi-natural experiments and uses differences-in-differences(DID)methods to analyze their effects on enterprise profitability and profit quality,respectively.The results show that:first,the CCPS significantly improve both profitability and profit quality;that is,the implementation of the environmental regulation policy plays a significant role in improving enterprise profit rates and cash flows.Second,for the profitability mediator effects,the short-term Porter effect of CCPS is not significant but shows the opposite during the lag period and significantly reduces the management cost and wage levels,comprehensively promoting enterprise profitability.Third,for the profit quality meditator effects,environmental regulations improve the enterprises'cash flow by reducing management costs and increasing government subsidies;however,its effect on bank credit subsidies is not significant.Fourth,for the moderator effects,the environmental regulations'effect on enterprises profitability and profit quality depends on the strategic interaction among local governments,the scale and ownership of the enterprise,and regional differences.That is,the strategic interaction weakens the effect of environmental regulations on enterprise performance.Environmental regulations have a stronger influence on profitability and profit quality for large-scale,state-owned,and coastal enterprises. 展开更多

The Israelite people began to have kings hundreds of years after the Mosaic Law was given to them from God,and with kings from David and then his family,they experienced no substantial dynastic changes in the southern kingdom of Judah.Later,the Israelites were ruled by kings or emperors of other nations until the State of Israel was restored in its historical land after World War Two.Without any written law comparable to the Mosaic Law,the earliest Zhou kings of China claimed to be Sons of Heaven and Heaven worship was inherited by later emperors.Heaven worship has features in common with the monotheistic religion of the Israelites,such as that a king should obey the will of God.With changes of dynasties,Heaven worship actually means that heaven could be renamed and the former Son of Heaven had no life-long priesthood in serving Heaven.After the redemptive work of Jesus Christ had fulfilled the Mosaic Law,Heaven worship had little relation with faith in God,the Creator. 展开更多
