Three decades of SOE reform:no pain,no gain

What lies ahead for China,difficulties or perhaps another three decades of glory? To address this question,a special event was held at Chongqing Technology and Business University:Symposium on Theories on and Reality of China’s 30 Years of Enterprise Reform and Development,annual meeting of the Chinese Institute of Business Administration for 2008. At the foot of a mountain just south of Chongqing,150 delegates in the field of economic research gathered for discussions on pains and gains of the 30 years of reform. Leading economists at the event included Chen Jiagui,vice president of Chinese Academy of Social Sciences (CASS),Zhang Guoyou,vice president of Peking University,and Jin Bei,deputy director of CASS’s Institute of Industrial Economics (IIE). The symposium was jointly sponsored by the Chinese Institute of Business Administration,Jiang Yiwei Academic Foundation for Enterprise Reform and Development,Chongqing Technology and Business University,and CASS Management Science Research Institute. The following is a group of articles written by staff reporters of the China Economist (CE).

Changes in body composition of women at different age decades and its relation with to metabolic risks

Objective: Aim of this study was to investigate the changes in body composition and some biochemical parameters of women at different age and body mass index (BMI) groups and to evaluate their relations with to cardiometabolic risk factors. Methods: The study was created by retrospective research of the file records of total 800 women who got into nutritional counseling between 2002 - 2007 years at Cerrahpasa Medical Faculty. Participants were grouped as 10 - 19, 20 - 29, 30 - 39, 40 - 49, 50 - 59, ≥60 years according to ages and were divided into 4 groups as normal, overweight, obese and morbidly obese according to body mass index. Data were statistically analysed in SPSS for Windows computer program with ANOVA and Tukey HSD tests. Findings: There are significant differences between different age groups in weight, BMI, waist and hip circumferences, percentage of body water, fat and fat-free mass, basal metabolic rate and blood glucose, insulin, triglyceride, cholesterol, HDL, LDL levels and HOMA-IR values. HOMA-IR values were the highest at age group 1 and the lowest at age group 2. Although they were in the same BMI group;their waist circumference, basal metabolic rate and percent of body fat showed significant increases with advancing age. Conclusion: The findings of our study show that it will be useful to use standard values generated for each age group according to BMI levels in predicting increased cardiovascular and metabolic risks together with advancing age. While the lowest rate of obesity according to body fat percent (>30%) was found at the ages in between 20 - 29 (58.4%), it is noteworthy that the obesity rate with respect to their body fat percent has been noticed at the ages of 10 to 19 (2.3%). Comparing with the other groups, significantly higher body heights found at the ages in between 10 - 19, could possibly predicate that the new generations are having better nutrition and overhaul. On the other hand, it was known that as a result of eating bugs and/or over-nutrition, besides insertion of inactive life style, children have become more sensitive to obesity and related health problems. As seen in our study, the healthiest values are at the ages in between 20 - 29, the results were commentated as the women at those ages are showing more interest in their physical appearance and their health. In accordance with our study’s data, in order to cope with obesity and related illnesses, which are having an importance in public health, we concluded that generalizing continuous and effective trainings on nutrition concerning families even the educators starting from the childhood, can be usefull.

Lawyers' Role Greater in China's Legal System——A review of legal services in China over the past two decades

Lawyers play no small a role in improving China’s legal system, which comes along with the country’s endeavor to build a market-oriented economy and open to the outside world. Legal services provided by lawyers have virtually become available to all sectors of society since the country adopted the policy of reform and opening up in the late 1970s.

Fruitful Cooperation between CAS and Japanese Scientists Over the Past Three Decades

Ⅰ. From the Civilian Contact to the Dual Channel of Official and Non-governmental Exchanges From 1949 to 1972, S&T exchanges between China and Japan were dominated by civilian contacts,as non-governmental channels were used to intermediate between the two governments. In 1955, a delegation of Chinese scientists visited Japan under the leadership of Guo Moruo, the first president of CAS,and met with Japanese scientists and friends from all walks of life.

My Reporti Decades In Tibet

I am 61 years old. My hometown is Batang, now part of Sichuan Province. Driven by apoor life, father joined the KMT five days after I was born. His troops went over to the PLA right before national liberation. He joined the PLA 18th Army and was sent into Tibet. On the morning of October 17,1950, the PLA forces marched from Mamkang and Dege toward Qamdo, which was garrisoned by Tibetan troops. The latter soon surrendered or were routed. Qamdo was liberated on the 19th. On May 23,1951, the Central Government and the local government of Tibet signed an agreement for the peaceful liberation of Tibet.Join the PLA When 11I joined the PLA to follow in my father’s footsteps in 1951, when I was only 11.1 left Batang on

The Hiatus and Accelerated Warming Decades in CMIP5 Simulations

Observed hiatus or accelerated warming phenomena are compared with numerical simulations from the Coupled Model Intercomparison Project Phase 5 （CMIP5） archives,and the associated physical mechanisms are explored based on the CMIP5 models.Decadal trends in total ocean heat content （OHC） are strongly constrained by net top-of-atmosphere （TOA） radiation.During hiatus decades,most CMIP5 models exhibit a significant decrease in the SST and upper OHC and a significant increase of heat penetrating into the subsurface or deep ocean,opposite to the accelerated warming decades.The shallow meridional overturning of the Pacific subtropical cell experiences a significant strengthening （slowdown） for the hiatus （accelerated warming） decades associated with the strengthened （weakened） trade winds over the tropical Pacific.Both surface heating and ocean dynamics contribute to the decadal changes in SST over the Indian Ocean,and the Indonesian Throughflow has a close relationship with the changes of subsurface temperature in the Indian Ocean.The Atlantic Meridional Overturing Circulation （Antarctic Bottom Water） tends to weaken （strengthen） during hiatus decades,opposite to the accelerated warming decades.In short,the results highlight the important roles of air-sea interactions and ocean circulations for modulation of surface and subsurface temperature.

Has the East Asian Westerly Jet Experienced a Poleward Displacement in Recent Decades?

Previous studies have suggested a poleward shift of the zonally averaged jet stream due to rapid warming over continents.However,the regional characteristics of the change in the jet stream are not yet understood.Here,we present evidence suggesting that the East Asian westerly jet did not shift poleward in past decades（1980-2004 relative to 1958-1979）,both in winter and summer.Rather,the jet axis has moved southward in summer,but its meridional position is steady in winter.The main change of the jet stream in winter is the enhancement of its intensity.These changes in both summer and winter are consistent with the corresponding changes in the large meridional tropospheric temperature-gradient zone.Based on these results,we suggest that the changes of the jet stream over East Asia are unique and are different from the zonal mean jet stream over the Northern Hemisphere and over the North Atlantic region.

Changes in Vegetation and Rainfall over West Africa during the Last Three Decades (1981-2010)

The decadal variability of rainfall and vegetation over West Africa have been studied over the last three decades, 1981-1990, 1991-2000 and 2001-2010 denoted as 1980s, 1990s and 2000s, respectively. Climate Research Unit (CRU) monthly precipitation and Normalized Difference Vegetation Index (NDVI) from the National Oceanic and Atmosphere Administration (NOAA), all covering the period 1981-2010 have been used. This study aimed to assess the changes in the land surface condition and the spatio-temporal distribution of rainfall over West Africa region. The relationship between rainfall and vegetation indices over this region was determined using Pearson’s correlation. Also, the decadal comparison between rainfall and NDVI over the region was based on the significant t-test and the Pearson’s correlation. Results showed that significant return to wet conditions is observed between decade 1980s and decade 1990s over West Africa, and also during decade 2000s with the exception of central Benin and the western Nigeria. Meanwhile, a regreening of the central Sahel and Sudano-Sahel regions is noted. From 1990s to 2000s, this regreening belt is located in the South and the coastal areas: the Guinea Coast, Sudano-Guinea and western Sahel regions. A northward displacement of this re-greening belt is also detected. Thus, a linear relationship occurs between rainfall and NDVI in the Sudanian savannah region, but it is not the case in the rest of West Africa. This may suggest that the re-growth of vegetation in the Sudanian savannah region may be linked to rainfall supplies. Therefore, re-greening over Sahel region in 1990s is related to rainfall recovery. However, this re-greening was not sustained in the decade 2000s due to a slight decrease in rainfall.

Anthropogenic Influence on Decadal Changes in Concurrent Hot and Dry Events over China around the Mid-1990s

The frequency and duration of observed concurrent hot and dry events(HDEs) over China during the growing season(April–September) exhibit significant decadal changes across the mid-1990s. These changes are characterized by increases in HDE frequency and duration over most of China, with relatively large increases over southeastern China(SEC), northern China(NC), and northeastern China(NEC). The frequency of HDEs averaged over China in the present day(PD,1994–2011) is double that in the early period(EP, 1964–81);the duration of HDEs increases by 60%. Climate experiments with the Met Office Unified Model(MetUM-GOML2) are used to estimate the contributions of anthropogenic forcing to HDE decadal changes over China. Anthropogenic forcing changes can explain 60%–70% of the observed decadal changes,suggesting an important anthropogenic influence on HDE changes over China across the mid-1990s. Single-forcing experiments indicate that the increase in greenhouse gas(GHG) concentrations dominates the simulated decadal changes,increasing the frequency and duration of HDEs throughout China. The change in anthropogenic aerosol(AA) emissions significantly decreases the frequency and duration of HDEs over SEC and NC, but the magnitude of the decrease is much smaller than the increase induced by GHGs. The changes in HDEs in response to anthropogenic forcing are mainly due to the response of climatological mean surface air temperatures. The contributions from changes in variability and changes in climatological mean soil moisture and evapotranspiration are relatively small. The physical processes associated with the response of HDEs to GHG and AA changes are also revealed.

Root morphology in response to nitrogen supply in mid-season indica rice cultivars released in different decades

Dear Editor,Roots,as a major organ of plants,are involved in nutrient and water acquisition,and might play a vital role in yield increase and efficient N absorption with genetic improvement.Because of the great differences in growth period and pattern between the old and new rice cultivars,it is difficult to clarify how genetic improvements contribute to root growth in rice.For example,for a solution culture system,Wu et al.suggested that total root length increased with increasing year of release for maize hybrids,while shoot dry weight,

CMIP 6 models simulation of the connection between North/South Pacific Meridional Mode and ENSO

The subtropical North and South Pacific Meridional Modes(NPMM and SPMM)are well known precursors of El Niño-Southern Oscillation(ENSO).However,relationship between them is not constant.In the early 1980,the relationship experienced an interdecadal transition.Changes in this connection can be attributed mainly to the phase change of the Pacific decadal oscillation(PDO).During the positive phase of PDO,a shallower thermocline in the central Pacific is responsible for the stronger trade wind charging(TWC)mechanism,which leads to a stronger equatorial subsurface temperature evolution.This dynamic process strengthens the connection between NPMM and ENSO.Associated with the negative phase of PDO,a shallower thermocline over southeastern Pacific allows an enhanced wind-evaporation-SST(WES)feedback,strengthening the connection between SPMM and ENSO.Using 35 Coupled Model Intercomparison Project Phase 6(CMIP6)models,we examined the NPMM/SPMM performance and its connection with ENSO in the historical runs.The great majority of CMIP6 models can reproduce the pattern of NPMM and SPMM well,but they reveal discrepant ENSO and NPMM/SPMM relationship.The intermodal uncertainty for the connection of NPMM-ENSO is due to different TWC mechanism.A stronger TWC mechanism will enhance NPMM forcing.For SPMM,few models can simulate a good relationship with ENSO.The intermodel spread in the relationship of SPMM and ENSO owing to SST bias in the southeastern Pacific,as WES feedback is stronger when the southeastern Pacific is warmer.

Highlights of genetics research over the past four decades in China

The year of 2018 marks China’s 40th anniversary of the reform and opening up. Coincidently, this year is also the 40th anniversary of Genetics Society of China (GSC), one of the largest academic organizations in China. In October of 1978, GSC was formally established in Nanjing, ushering a new era of genetics research in China, and its mission is to promote genetics research and education.Genetics focuses on the study of genes, genetic variations, and heredity in living organisms. It has permeated every field of
