Die, Hu; Lei, Zhang; Hongbin, Wang

2014-01-01

In this study, Aerosol Optical Depth (AOD) at 550nm from the MODIS sensor on board the Terra/Aqua satellites were compared with sun photometer (CE-318) measurements from 11 AERONET stations in China. The average correlation coefficient (R) value from the AOD product, using the Aqua-MODIS Deep Blue algorithm, in the Hexi Corridor was 0.67. The MODIS Dark Target algorithm AOD product is superior to Deep Blue algorithm AOD products in SACOL of the Semi-arid regions of the Loess Plateau. These two kinds of algorithm are not applicable to sites in Lanzhou city. The average R value of Dark Target algorithm AOD MODIS products is 0.91 for Terra and 0.88 for Aqua in the eastern part of China. According to the analysis of spatial and temporal characteristics of the two MODIS AOD products in China, high value areas are mainly distributed in the southern part of Xinjiang (0.5∼0.8), Sichuan Basin (0.8∼0.9), North China (0.6∼0.8) and the middle and lower reaches of the Changjiang River (0.8∼1.0). The Deep Blue algorithm for Aqua-MODIS is a good supplement for the retrieval of AOD above bright surfaces of deserts in Northwest China

Industrialization of bio-energy relies on the supply of resources on a large scale. The theoretical biomass resources could reach 2.61-3.51 billion tce (tons of coal equivalent)/a in China, while the available feedstock is about 440-640 million tce/a, however, among this only 1.5-2.5% has been transferred into energy at present. Marginal land utilization has great prospects of supplying bio-energy resources in China, with co-benefits, such as carbon sequestration, water/soil conservation, and wind erosion protection. There is a large area of marginal land in China, especially in northern China, including about 263 million ha of desertification land, 173 million ha of sand-land, and 17 million ha of salinizatin land. The plant species suitable to be grown in marginal lands, including some species in Salix, Hippophae, Tamarix, Caragana, and Prunus is also abundant Biomass feedstock in marginal lands would be 100 million tce/a in 2020, and 200 million tce/a in 2050. As a result, a win-win situation of eco-society and bio-energy development could be realized, with an expected 4-5% reduction of total CO{sub 2} emission in China in 2020-2050. Although much progress has been made in the field of bio-energy research in China, yet significant efforts should be taken in the future to fulfill large-scale industrialization of bio-energy.

There is a large uncertainty in evaluating the radiative forcing from aerosol–radiation and aerosol–cloud interactions due to the limited knowledge on aerosol properties. In-situ measurements of aerosol physical and chemical properties were carried out in 2012 at Mt. Huang (the Yellow Mountain), a continental background mountainous site in eastern China. An aerosol optical closure study was performed to verify the model outputs by using the measured aerosol optical properties, in which a spherical Mie model with assumptions of external and core–shell mixtures on the basis of a two-component optical aerosol model and high size-segregated element carbon (EC) ratio was applied. Although the spherical Mie model would underestimate the real scattering with increasing particle diameters, excellent agreement between the calculated and measured values was achieved with correlation coefficients above 0.98. Sensitivity experiments showed that the EC ratio had a negligible effect on the calculated scattering coefficient, but largely influenced the calculated absorption coefficient. The high size-segregated EC ratio averaged over the study period in the closure was enough to reconstruct the aerosol absorption coefficient in the Mie model, indicating EC size resolution was more important than time resolution in retrieving the absorption coefficient in the model. The uncertainties of calculated scattering and absorption coefficients due to the uncertainties of measurements and model assumptions yielded by a Monte Carlo simulation were ± 6% and ± 14% for external mixture and ± 9% and ± 31% for core–shell mixture, respectively. This study provided an insight into the inherent relationship between aerosol optical properties and physicochemical characteristics in eastern China, which could supplement the database of aerosol optical properties for background sites in eastern China and provide a method for regions with similar climate. - Highlights: • A spherical Mie

Nicholson Medal Lecture: Scientists and Totalitarian Societies

Fang, Li-Zhi

1997-04-01

In order to call for support for his policy in China from the scientific community outside of China, Li Peng, China's premier today and at the time of Tiananmen massacre in 1989, published an editorial of ``Science" magazine (July 5, 1996) titled ``Why China needs science ... and partners." This editorial brought a serious problem, which is originally faced by scientists in a totalitarian society, upon the scientific community in free societies outside. It is well known that the current attitude of the Chinese government toward science is what it was during the years of Mao and the Soviet Union: science is limited to provide instruments useful to the rulers, but any degree of freedom, such as to challenge ideas, required by science to change the totalitarian regime itself, is suppressed. Thus, the problem facing us is: how to help your colleagues and promote science in a totalitarian society, without becoming a partner of the injustices of that regime.

Wenjing, Jin; Bai, Jinming; Yao, Yongqiang

2015-03-01

Before 1950 there are two observatories, Shanghai and Purple Mountain Astronomical Observatories (SHAO and PMO), and two observing stations, Qingdao and Kunming stations in China. With the requirements of astronomical research, two observatories, Beijing and Shaanxi Astronomical Observatories (BAO and SXAO) and two artificial satellite stations, Urumqi and Changchun, were established about 1960. Based on the current management, now there are 4 observatories, SHAO, PMO, NAOC(National Astronomical Observatories), which was grouped from BAO, YNAO and 2 others, as well as XAO (Xinjiang Astronomical Observatory). The optical 1-2 m class telescopes are being operated at former four observatories. SXAO is changed as National Time Service Center. Because of city expansion as well as the traveling and economic developments, these observatories are suffered severe light pollution. For example, Zo Ce is located at the suburb of Shanghai city. A 40 cm double astrograph was installed in 1900 and a 1.56 m optical reflector have been operated since November 1987. In 1994 the seeing is better than 1 and the night sky brightness in V is about 19 mag/arcsec 2, stars fainter than 20 mag with CCD are visibles. In 2007 a large playground was built in Zô Cè area. The light pollution is severe gradually. The night sky brightness has been increased to 15.8 mag/arcsec 2. The other observatories have similar situation. New site surveys and found new stations to solve the problem. Except the solar and radio stations of each Astronomical Observatory, now there are 3 optical observing sites at PMO (Hong-He, Xu-Yi and Yaoan), 2 at SHAO (Zô Cè and Tian Huang Ping) and 2 at YNAO (Kunming and Gao-Mei-Gu) as well as 1 optical observing site at BAO (Xing-Long). The best observing site is Gao-Mei-Gu, which is selected as the optical observing site of YNAO and where atmospheric turbulence distribution is 0.11 near ground with heights from 6.5m to 2.7m during night.

The Migration, Mental Stress, and Tobacco use of Internal Migrants in China: The Moderating Effect of the Social Context of the Host Society.

Science.gov (United States)

Xie, Shenghua

2017-11-10

Previous studies on the relationship between mental stress and the tobacco use of internal migrants have not fully considered the social context of the host society. This study aims to examine how mental stress influences cigarette smoking in internal migrants in China by considering the social context of the host society. We used the RUMiC data that were collected in 15 cities distributed throughout 9 provinces of China. A total of 8,446 and 5,426 migrant workers were interviewed in 2008 and 2009, respectively. We selected individuals based on the criteria of age, salary, and hukou status. A total of 8,880 observations are valid for this study. This research used the logistic regression method to test the association between mental stress and the tobacco use of internal migrants. The results show that mental stress is not necessarily associated with the tobacco use of internal migrants. However, the effects of mental stress on tobacco use are moderated by the social context of the host society. This article calls for more attention to be paid to the moderate effect of social context in the host society on the association between mental stress and cigarette smoking of internal migrants. Moreover, this article underscores the importance of factors related to local societies in making and enacting tobacco control policies for migrants in developing countries.

China is undergoing rapid changes in sexual mores due to several reasons such as decreasing control of the state over private lives of individuals, globalization of its economy, and some policies initiated by the state. There is increased acceptance of premarital sex and extramarital sex in China, especially among youth. In historically conservative China, influenced by Confucian ideals of patriarchal dominance for centuries, the sexual freedom currently enjoyed by many is unprecedented. This has impacted women's status and sexual lives in several positive ways such as increasing freedom of sexual expression, control over their bodies, sexual choices, and increasing equality with men in all spheres of life. However several negative consequences such as a rise in STD/HIV prevalence, commercial sex, and divorce rates have also been attributed to the ongoing sexual revolution in China. Recommendations combating these and suggestions for directions in future research are discussed.

OMS'05 is the first international conference wholly dedicated to optical microsystems. It was organized by the European Optical Society (EOS) in the frame of its international topical meeting activity and was held in Italy, September 2005, amidst the wonderful scenery of the Island of Capri. A possible definition of an optical microsystem is a complex system, able to perform one or more sensing and actuation functions, where optical devices are integrated in a smart way with electronic, mechanical and sensing components by taking advantage of the progress in micro- and nano-technologies. The increasing interest in this field arises from the expected applications that would significantly improve the quality of life. The list of possibilities offered by the optical microsystem enabling technologies is very long and seems to increase day by day. We are not only thinking about the next generation of optical telecommunication networks and computers, but also about low-cost, compact microsystems for environmental monitoring, in order to improve safety in the avionic and automotive fields, medical diagnostics and proteomic/genomic studies, or just finding general applications in several industrial fields. The goal of the conference was to involve scientists and young researchers from the main public and private laboratories, giving them the opportunity to present new scientific results and compare their know-how in the exciting and emerging field of optical microsystems. We believe that we succeeded in this. More than 200 scientists from all over the world attended the conference. We had more than 100 oral presentations and approximately 20 from the keynote lectures and invited speeches. It was an opportunity to define the most recent progress carried out in the field and to outline the possible road-map leading to the expected results in the industrial and social fields. We strongly believe that research and technology are closely interconnected at present and cannot

Distributed acoustic sensing (DAS) is a new type of replacement technology for geophysical geophone. DAS system is similar to high-density surface seismic geophone array. In the stage of acquisition, DAS can obtain the full well data with one shot. And it can provide enhanced vertical seismic profile (VSP) imaging and monitor fluids and pressures changes in the hydrocarbon production reservoir. Walkaway VSP data acquired over a former producing well in north eastern China provided a rich set of very high quality data. A standard VSP data pre-processing workflow was applied, followed by pre-stack Kirchhoff time migration. In the DAS pre-processing step we were faced with additional and special challenges: strong coherent noise due to cable slapping and ringing along the borehole casing. The single well DAS Walkaway VSP images provide a good result with higher vertical and lateral resolution than the surface seismic in the objective area. This paper reports on lessons learned in the handling of the wireline cable and subsequent special DAS data processing steps developed to remediate some of the practical wireline deployment issues. Optical wireline cable as a conveyance of fiber optic cables for VSP in vertical wells will open the use of the DAS system to much wider applications.

Aerosol observational data for 2012 obtained from Dunhuang Station of CARE-China (Campaign on Atmospheric Aerosol Research Network of China) were analyzed to achieve in-depth knowledge of aerosol optical properties over Dunhuang region. The results showed that the annual average aerosol optical depth (AOD) at 500 nm was 0.32±0.06, and the Ångström exponent ( α) was 0.73 ± 0.27. Aerosol optical properties revealed significant seasonal characteristics. Frequent sandstorms in MAM (March-April-May) resulted in the seasonal maximum AOD, 0.41 ± 0.04, and a relatively smaller α value, 0.44±0.04. The tourism seasons, JJA (June-July-August) and SON (September-October-November) coincide with serious emissions of small anthropogenic aerosols. While in DJF (December-January-February), the composition of the atmosphere was a mixture of dust particles and polluted aerosols released by domestic heating; the average AOD and α were 0.29 ± 0.02 and 0.66 ± 0.17, respectively. Different air masses exhibited different degrees of influence on the aerosol concentration over Dunhuang in different seasons. During MAM, ranges of AOD (0.11-1.18) and α (0.06-0.82) were the largest under the dust influence of northwest-short-distance air mass in the four trajectories. Urban aerosols transported by northwest-short-distance air mass accounted for a very large proportion in JJA and the mixed aerosols observed in SON were mainly conveyed by air masses from the west. In DJF, the similar ranges of AOD and α under the three air mass demonstrated the analogous diffusion effects on regional pollutants over Dunhuang.

H. Che

2008-06-01

Full Text Available This study compares the aerosol optical and physical properties simultaneously measured by a SKYNET PREDE skyradiometer and AERONET/PHOTONS CIMEL sunphotometer at a location in Beijing, China. Aerosol optical properties (AOP including the Aerosol Optical Depth (AOD, Angstrom exponent (α, volume size distribution, single scattering albedo (ω and the complex refractive index were compared. The difference between the two types of instruments was less than 1.3% for the AOD and less than 4% for the single scattering albedo below the wavelength of 670 nm. There is a difference between the volume size distribution patterns derived from two instruments, which is probably due to difference of measurement protocols and inversion algorithms for the respective instruments.

AOP under three distinct weather conditions (background, haze, and dust days over Beijing were compared by using the retrieved skyradiometer and sunphotometer data combined with MODIS satellite results, pyranometer measurements, PM₁₀ measurements, and backtrajectory analysis. The results show that the significant difference of AOP under background, haze, and dust days over Beijing is probably due to different aerosol components under distinct weather conditions.

Full Text Available Aerosols greatly influence global and regional atmospheric systems, and human life. However, a comprehensive understanding of the source regions and three-dimensional (3D characteristics of aerosol transport over central China is yet to be achieved. Thus, we investigate the 3D macroscopic, optical, physical, and transport properties of the aerosols over central China based on the March 2007 to February 2016 data obtained from the Cloud–Aerosol Lidar and Infrared Pathfinder Satellite Observations (CALIPSO mission and the hybrid single-particle Lagrangian integrated trajectory (HYSPLIT model. Our results showed that approximately 60% of the aerosols distributed over central China originated from local areas, whereas non-locally produced aerosols constituted approximately 40%. Anthropogenic aerosols constituted the majority of the aerosol pollutants (69% that mainly distributed less than 2.0 km above mean sea level. Natural aerosols, which are mainly composed of dust, accounted for 31% of the total aerosols, and usually existed at an altitude higher than that of anthropogenic aerosols. Aerosol particles distributed in the near surface were smaller and more spherical than those distributed above 2.0 km. Aerosol optical depth (AOD and the particulate depolarization ratio displayed decreasing trends, with a total decrease of 0.11 and 0.016 from March 2007 to February 2016, respectively. These phenomena indicate that during the study period, the extinction properties of aerosols decreased, and the degree of sphericity in aerosol particles increased. Moreover, the annual anthropogenic and natural AOD demonstrated decreasing trends, with a total decrease of 0.07 and 0.04, respectively. This study may benefit the evaluation of the effects of the 3D properties of aerosols on regional climates.

A brief review of recent progress in researches, productions and applications of full distributed fiber Raman photon sensors at China Jiliang University (CJLU) is presented. In order to improve the measurement distance, the accuracy, the space resolution, the ability of multi-parameter measurements, and the intelligence of full distributed fiber sensor systems, a new generation fiber sensor technology based on the optical fiber nonlinear scattering fusion principle is proposed. A series of new generation full distributed fiber sensors are investigated and designed, which consist of new generation ultra-long distance full distributed fiber Raman and Rayleigh scattering photon sensors integrated with a fiber Raman amplifier, auto-correction full distributed fiber Raman photon temperature sensors based on Raman correlation dual sources, full distributed fiber Raman photon temperature sensors based on a pulse coding source, full distributed fiber Raman photon temperature sensors using a fiber Raman wavelength shifter, a new type of Brillouin optical time domain analyzers (BOTDAs) integrated with a fiber Raman amplifier for replacing a fiber Brillouin amplifier, full distributed fiber Raman and Brillouin photon sensors integrated with a fiber Raman amplifier, and full distributed fiber Brillouin photon sensors integrated with a fiber Brillouin frequency shifter. The Internet of things is believed as one of candidates of the next technological revolution, which has driven hundreds of millions of class markets. Sensor networks are important components of the Internet of things. The full distributed optical fiber sensor network (Rayleigh, Raman, and Brillouin scattering) is a 3S (smart materials, smart structure, and smart skill) system, which is easy to construct smart fiber sensor networks. The distributed optical fiber sensor can be embedded in the power grids, railways, bridges, tunnels, roads, constructions, water supply systems, dams, oil and gas pipelines and other

People's Republic of China's Contemporary Migration Processes

Directory of Open Access Journals (Sweden)

Martina Bofulin

2014-12-01

Full Text Available The last three decades of significant political, economic and social transformations in the People’s Republic of China have had a profound impact on the Chinese society. The article addresses selected topics of Chinese migration that give a more nuanced understanding of migration processes and their contextualization within the contemporary Chinese society: the internal migration, emigration from China and international immigration to China. Migration from rural area towards urban eastern coast is one of the largest spatial movements in the human history, as well as a key component of the economic rise and subsequent social change. Emigration from China has, despite its relatively small volume, profoundly transformed local places of origin, a process that is not independent from the current international geopolitical situation. Immigration of international migrants to China is a relatively new phenomenon that puts the country on the map of migration destination countries for the first time in sixty years. The author concludes that the prevalent research perspectives on Chinese migration offer only a limited insight and suggests some possible alternative ways of analyzing this phenomenon.

China's water scarcity.

Science.gov (United States)

Jiang, Yong

2009-08-01

China has been facing increasingly severe water scarcity, especially in the northern part of the country. China's water scarcity is characterized by insufficient local water resources as well as reduced water quality due to increasing pollution, both of which have caused serious impacts on society and the environment. Three factors contribute to China's water scarcity: uneven spatial distribution of water resources; rapid economic development and urbanization with a large and growing population; and poor water resource management. While it is nearly impossible to adjust the first two factors, improving water resource management represents a cost-effective option that can alleviate China's vulnerability to the issue. Improving water resource management is a long-term task requiring a holistic approach with constant effort. Water right institutions, market-based approaches, and capacity building should be the government's top priority to address the water scarcity issue.

Aerosol optical properties and radiative effects: Assessment of urban aerosols in central China using 10-year observations

2018-06-01

Poor air quality episodes are common in central China. Here, based on 10 years of ground-based sun-photometric observations, aerosol optical and radiative forcing characteristics were analyzed in Wuhan, the biggest metropolis in central China. Aerosol optical depth (AOD) in the last decade declined significantly, while the Ångström exponent (AE) showed slight growth. Single scattering albedo (SSA) at 440 nm reached the lowest value (0.87) in winter and highest value (0.93) in summer. Aerosol parameters derived from sun-photometric observations were used as input in a radiative transfer model to calculate aerosol radiative forcing (ARF) on the surface in ultraviolet (UV), visible (VIS), near-infrared (NIR), and shortwave (SW) spectra. ARFSW sustained decreases (the absolute values) over the last 10 years. In terms of seasonal variability, due to the increases in multiple scattering effects and attenuation of the transmitted radiation as AOD increased, ARF in summer displayed the largest value (-73.94 W/m2). After eliminating the influence of aerosol loading, the maximum aerosol radiative forcing efficiency in SW range (ARFESW) achieved a value of -64.5 W/m2/AOD in April. The ARFE change in each sub-interval spectrum was related to the change in SSA and effective radius of fine mode particles (Refff), that is, ARFE increased with the decreases in SSA and Refff. The smallest contribution of ARFENIR to ARFESW was 34.11% under strong absorbing and fine particle conditions, and opposite results were found for the VIS range, whose values were always over 51.82%. Finally, due to the serious air pollution and frequency of haze day, aerosol characteristics in haze and clear days were analyzed. The percentage of ARFENIR increased from 35.71% on clear-air days to 37.63% during haze periods, while both the percentage of ARFEUV and ARFENIR in ARFESW kept decreasing. The results of this paper should help us to better understand the effect of aerosols on solar spectral radiation

A case study of the highly time-resolved evolution of aerosol chemical and optical properties in urban Shanghai, China

Y. Huang

2013-04-01

Full Text Available Characteristics of the chemical and optical properties of aerosols in urban Shanghai and their relationship were studied over a three-day period in October 2011. A suite of real-time instruments, including an Aerosol Time-Of-Flight Mass Spectrometer (ATOFMS, a Monitor for AeRosols and GAses (MARGA, a Cavity Ring Down Spectrometer (CRDS, a nephelometer and a Scanning Mobility Particle Sizer (SMPS, was employed to follow the quick changes of the aerosol properties within the 72 h sampling period. The origin of the air mass arriving in Shanghai during this period shifted from the East China Sea to the northwest area of China, offering a unique opportunity to observe the evolution of aerosols influenced by regional transport from the most polluted areas in China. According to the meteorological conditions and temporal characterizations of the chemical and optical properties, the sampling period was divided into three periods. During Period 1 (00:00–23:00 LT, 13 October, the aerosols in urban Shanghai were mainly fresh and the single scattering albedo varied negatively with the emission of elemental carbon, indicating that local sources dominated. Period 2 (23:00 LT on 13 October to 10:00 LT on 15 October was impacted by regionally transported pollutants and had the highest particulate matter (PM mass loading and the lowest particle acidity, characterized by large fractions of aged particles and high secondary ion (nitrate, sulfate and ammonium mass concentrations. Comparison between ATOFMS particle acidity and quantitative particle acidity by MARGA indicated the significance of semi-quantitative calculation in ATOFMS. Two sub-periods were identified in Period 2 based on the scattering efficiency of PM1 mass. Period 3 (from 10:00 LT on 15 October to 00:00 LT on 16 October had a low PM1/PM10 ratio and a new particle formation event. The comparison of these sub-periods highlights the influence of particle mixing state on aerosol optical properties

CHINA’S ROLE AND STATUS IN INTERNATIONAL SOCIETY: SHOULD ITS RISE BE PERCEIVED AS A ‘THREAT’?

Dahlia Patricia Sterling

Full Text Available China has been making strides in numerous areas the entire world is still trying to grapple with and determine in what way China’s economic growth, active engagement and participation in the world system will affect nation states. Without a doubt, this has added increasing pressure and brought complications for China in continuously explaining its economic growth to a number of actors who perceive its growth and active participation in international society as a “threat”. In effect, China is still yet to define completely its new role in international society even today, and is still using its foreign policy principles and approaches in its participatory role in international society. Moreover, despite honoring its commitments to international society, it still plays a comparatively lesser role in the shaping and making of rules and regulations. Thus, rather than developing and creating new comprehensive policies geared towards shaping and making new rules and regulations to guide its action and roles in international society given that numerous changes have occurred in the world, such as more and more civil conflicts, humanitarian crisis and rogue leaders on the rise today, etc.; China needs to make changes to ensure that not only its voice is heard, but its rules and regulations are up-to-date, works and applicable along with its spoken voice. Based on these assumptions and debates, it is therefore reasonable to make an attempt to determine China’s role and status in its involvement in international society and its rise to become a global power, given its participation in international society which plays a significant part in the way the world perceives China’s rise. On this basis, the article intends to attempt to unravel China’s role and status in international society, the limitations and challenges China faces and the perception of its threat in becoming a “rising” global power.

Li, En-Chang

2008-09-01

Historically, the preconditions for the emergence of bioethics in China. were political reforms and their applications. The Hanzhong Euthanasia Case and the publication of Qiu Ren-zong's academic work Bioethics played a significant role in the development of bioethics in China. Other contributory factors include the establishment of the Chinese Society of Medical Ethics/Chinese Medical Association (C.M.A), the publication of the Journal of Chinese Medical Ethics, and the teaching and education of bioethics in China. Major achievements of bioethics in China include the establishment of ethics committee and ethics review system, active international communication and cooperation among the academic circles, and the successful management of the 8th World Congress of Bioethics in Beijing in 2006. Chinese bioethics focus on native Chinese realities and conditions, absorb the international research achievements in relevant fields, and combine international ideas with traditional Chinese doctrines. Admittedly, there are still some aspects to be improved, yet bioethics has attracted a lot of attention from the core leadership in China and has gained sound financial support, which augers well for its further development. This article also briefly introduces the development of bioethics in Hong Kong and Taiwan, China.

Aerosol and water vapor radiative forcings, shortwave atmospheric heating rates and longwave atmospheric cooling rates were determined based on in situ physical and chemical measurements of aerosol, associated with the Mie theory and a radiative transfer model, LOWTRAN7, during the two haze episodes in the winter of 2013 in Tianjin, China. The aerosol types considered in LOWTRAN7 included rural, urban, marine, desert and custom aerosols. The default ratio of the absorption coefficient to the extinction coefficient for urban aerosol in LOWTRAN7 was approximately double of those found in this work, implying the weaker absorption ability of aerosols in the North China Plain (NCP). Moreover, the aerosol is assumed to be evenly distributed below 1 km of planetary boundary layer (PBL) on hazy days in LOWTRAN7. If the default urban aerosol optical properties and extinction profile in LOWTRAN7 is employed directly, a larger energy imbalance between the atmosphere and surface is generated and the warming effect of the aerosol is magnified. Hence, modified urban aerosol optical properties were established to replace the corresponding parameters' database in LOWTRAN7. The aerosol extinction profiles were obtained based on a 255-m meteorological tower and observed results from the studies about Tianjin. In the NCP, the aerosol had little impact on atmospheric counter radiation. The water vapor is the crucial factor that affects atmospheric counter radiation. Both modified high shortwave heating rates and longwave cooling rates occur near the surface due to the abundance of aerosol and water vapor. The modified net atmospheric heating rate near the surface is 1.2 K d-1 on hazy days and 0.3 K d-1 on non-hazy days. Compared with the default urban aerosol optical properties and its vertical distribution in LOWTRAN7, the feedback effect of the modified urban aerosol on the boundary layer may not necessarily result in a stable lower atmosphere, but depends on the aerosol light

The optical and radiative properties of aerosols during a severe haze episode from 15 to 22 December 2016 over Beijing, Shijiazhuang, and Jiaozuo in the North China Plain were analyzed based on the ground-based and satellite data, meteorological observations, and atmospheric environmental monitoring data. The aerosol optical depth at 500 nm was 1.4 as the haze pollution developed. The Ångström exponent was > 0.80 for most of the study period. The daily single-scattering albedo was > 0.85 over all of the North China Plain on the most polluted days and was > 0.97 on some particular days. The volumes of fine and coarse mode particles during the haze event were approximately 0.05-0.21 and 0.01-0.43 μm3, respectively—that is, larger than those in the time without haze. The daily absorption aerosol optical depth was about 0.01-0.11 in Beijing, 0.01-0.13 in Shijiazhuang, and 0.01-0.04 in Jiaozuo, and the average absorption Ångström exponent varied between 0.6 and 2.0. The aerosol radiative forcing at the bottom of the atmosphere varied from -23 to -227,-34 to -199, and -29 to -191 W m-2 for the whole haze period, while the aerosol radiative forcing at the top of the atmosphere varied from -4 to -98, -10 to -51, and -21 to -143 W m-2 in Beijing, Shijiazhuang, and Jiaozuo, respectively. Satellite observations showed that smoke, polluted dust, and polluted continental components of aerosols may aggravate air pollution during haze episodes. The analysis of the potential source contribution function and concentration-weighted trajectory showed that the contribution from local emissions and pollutants transport from upstream areas were 190-450 and 100-410 μg m-3, respectively.

Aerosol optical properties (AOPs) and supporting parameters - particle number size distributions, PM2.5 mass concentrations, and the concentrations of trace gases (NOx and NOy) - were measured at SORPES, a regional background station in Nanjing, China from June 2013 to May 2015. The aerosol was highly scattering: the average scattering coefficient was σsp = 403 ± 314 Mm-1, the absorption coefficient σap = 26 ± 19 Mm-1, and the single-scattering albedo SSA = 0.93 ± 0.03 for green light. The SSA in Nanjing appears to be slightly higher than published values from several other sites in China and elsewhere. The average Ångström exponent of absorption (AAE) for the wavelength range 370-950 nm was 1.04 and the AAE range was 0.7-1.4. These AAE values can be explained with different amounts of non-absorbing coating on pure black carbon (BC) cores and different core sizes rather than contribution by brown carbon. The AOPs had typical seasonal cycles with high σsp and σap in winter and low ones in summer: the averages were σsp = 544 ± 422 and σap = 36 ± 24 Mm-1 in winter and σsp = 342 ± 281 and σap = 20 ± 13 Mm-1 in summer. The intensive AOPs had no clear seasonal cycles, the variations in them were rather related to the evolution of pollution episodes. The diurnal cycles of the intensive AOPs were clear and in agreement with the cycle of the particle number size distribution. The diurnal cycle of SSA was similar to that of the air photochemical age, suggesting that the darkest aerosol originated from fresh traffic emissions. A Lagrangian retroplume analysis showed that the potential source areas of high σsp and σap are mainly in eastern China. Synoptic weather phenomena dominated the cycle of AOPs on a temporal scale of 3-7 days. During pollution episodes, modeled boundary layer height decreased, whereas PM2.5 concentrations and σsp and σap typically increased gradually and remained high during several days but decreased faster, sometimes by even more

As the capital of the most air-polluted Hebei province in China, Shijiazhuang has been suffering serious haze pollutions especially during wintertime. An integrated campaign for investigating aerosol optical properties under haze conditions over Shijiazhuang were carried out using a sunphotometer, an aethalometer and a lidar in the winter from late 2013 to early 2014. The results indicated that the haze episodes during the measurement period were severer and more frequent over Shijiazhuang than Beijing. Under heavy pollution conditions (PM2.5 > 150 μg/m3) over Shijiazhuang, fine-mode fractions of AOD500nm were larger than 0.80 with more dispersive angstrom exponent due to hygroscopic growth. The mean values of SSA over Shijiazhuang were smaller than those over Beijing both in this study and the severe haze episodes in January 2013, suggesting that there were more fine-mode absorbing particles over Shijiazhuang. More significant spectrally-dependence of imaginary part of refractive index over Shijiazhuang implies larger relative magnitude of brown carbon (BrC) as compared to Beijing. The black carbon (BC) measurement displayed extremely high records with a larger ratio of BC to PM2.5 (12.11% in average) comparing with other cities in China. The high carbonaceous aerosols (BC and BrC) should be attributed to large amounts of coal consumption. During the hazes with high BC concentrations, the daily maximal planetary boundary layer (PBL) heights were consistently lower than 500 m, implying the impacts of BC aerosols on the PBL development and hence enhance the surface haze pollution.

Information and telecommunication technologies (ITT) are already tool economic development of society and their role will grow. The first task is providing of information security of ITT that is necessary for it distribution in "information" society. The state policy of the leading world countries (USA, France, Japan, Great Britain and China) is focused on investment huge funds in innovative technologies development. Within the next 4-6 years the main fiber-optic transfer lines will have data transfer speed 40 Gbit/s, number of packed channels 60-200 that will provide effective data transfer speed 2,4-8 Tbit/s. Photonic-crystalline fibers will be promising base of new generation fiber-optic transfer lines. The market of information imaging devices and digital photo cameras will be grown in 3-5 times. Powerful lasers based on CO2 and Nd:YAG will be actively used in transport machinery construction when producing aluminum constructions of light rolling-stock. Light-emitting diodes (LEDs) will be base for energy saving and safety light sources used for vehicles and indoor lighting. For example, in the USA cost reducing for lighting will be 200 billion dollars. Implementation analysis of optic electronic photonic technologies (OPT) in ground and aerospace systems shows that they provide significant increasing of traffic safety, crew and passengers comfort with help of smart vehicles construction and non-contact dynamic monitoring both transport facilities (for example, wheel flanges) and condition of rail track (road surface), equipping vehicles with night vision equipment. Scientific-technical programs of JSC "RZD" propose application of OPT in new generation systems: axle-box units for coaches and freight cars monitoring when they are moved, track condition analysis, mechanical stress and permanent way irregularity detection, monitoring geometric parameters of aerial contact wire, car truck, rail and wheel pair roll surface, light signals automatic detection from

Professional societies sponsor student chapters in order to foster scholarship and training in photonics at the college and graduate level, but they are also an excellent resource for disseminating photonics knowledge to pre-college students and teachers. Starting in 2006, we tracked the involvement of SPIE student chapter volunteers in informal pre-college education settings. Chapter students reached 2800, 4900 and 11800 pre-college students respectively from 2006-2008 with some form of informal instruction in optics and photonics. As a case study, the EduKit, a self-contained instruction module featuring refractive and diffractive micro-optics developed by the European Network of Excellence on Micro-Optics (NEMO), was disseminated through student chapters in Argentina, Belgium, Canada, China, Colombia, India, Latvia, Mexico, Peru, Russia, Singapore, South Africa, and the United States. We tracked the movement of this material through the network, up to the student-teacher feedback stage. The student chapter network provided rapid dissemination of the material, translation of the material into the local language, and leveraged existing chapter contacts in schools to provide an audience. We describe the student chapter network and its impact on the development of the EduKit teaching module.

Accurate estimation of surface evapotranspiration (ET) with high quality is one of the biggest obstacles for routine applications of remote sensing in eco-hydrological studies and water resource management at basin scale. However, many aspects urgently need to deeply research, such as the applicability of the ET models, the parameterization schemes optimization at the regional scale, the temporal upscaling, the selecting and developing of the spatiotemporal data fusion method and ground-based validation over heterogeneous land surfaces. This project is based on the theoretically robust surface energy balance system (SEBS) model, which the model mechanism need further investigation, including the applicability and the influencing factors, such as local environment, and heterogeneity of the landscape, for improving estimation accuracy. Due to technical and budget limitations, so far, optical remote sensing data is missing due to frequent cloud contamination and other poor atmospheric conditions in Southwest China. Here, a multi-source remote sensing data fusion method (ESTARFM: Enhanced Spatial and Temporal Adaptive Reflectance Fusion Model) method will be proposed through blending multi-source remote sensing data acquired by optical, and passive microwave remote sensors on board polar satellite platforms. The accurate "all-weather" ET estimation will be carried out for daily ET of the River Source Region in Southwest China, and then the remotely sensed ET results are overlapped with the footprint-weighted images of EC (eddy correlation) for ground-based validation.

The past decades have witnessed interventional radiology in China to go from a very initial clinical practice to an important medical player in modern medicine. Recently, a friendly collaboration has been successfully established between the Chinese Interventional Radiology Sub-society and the Journal of Interventional Radiology. The Chinese Interventional Radiology Sub-society will take the full responsibility for the academic governance of the Journal of Interventional Radiology and the Journal of Interventional Radiology will formally become the sole interventional academic periodical of the Chinese Interventional Radiology Sub-society in China. This collaboration will surely make Chinese interventional radiology to initiate a new era,promote the further development of interventional radiology at home and enable the Journal of Interventional Radiology to step into the international medical circle.

Sb-doped GeSe2 chalcogenide thin films are prepared by the magnetron co-sputtering method. The linear optical properties of as-deposited films are derived by analyzing transmission spectra. The refractive index rises and the optical band gap decreases from 2.08 eV to 1.41 eV with increasing the Sb content. X-ray photoelectron spectra further confirm the formation of a covalent Sb-Se bond. The third-order nonlinear optical properties of thin films are investigated under femtosecond laser excitation at 800 nm. The results show that the third-order nonlinear optical properties are enhanced with increasing the concentration of Sb. The nonlinear refraction indices of these thin films are measured to be on the order of 10-18 m2/W with a positive sign and the nonlinear absorption coefficients are obtained to be on the order of 10-10 m/W. These excellent properties indicate that Sb-doped Ge-Se films have a good prospect in the applications of nonlinear optical devices.

Aerosol pollution in eastern China is an unfortunate consequence of the region's rapid economic and industrial growth. Here, sun photometer measurements from seven sites in the Yangtze River Delta (YRD) from 2011 to 2015 were used to characterize the climatology of aerosol microphysical and optical properties, calculate direct aerosol radiative forcing (DARF) and classify the aerosols based on size and absorption. Bimodal size distributions were found throughout the year, but larger volumes and effective radii of fine-mode particles occurred in June and September due to hygroscopic growth and/or cloud processing. Increases in the fine-mode particles in June and September caused AOD440 nm > 1.00 at most sites, and annual mean AOD440 nm values of 0.71-0.76 were found at the urban sites and 0.68 at the rural site. Unlike northern China, the AOD440 nm was lower in July and August (˜ 0.40-0.60) than in January and February (0.71-0.89) due to particle dispersion associated with subtropical anticyclones in summer. Low volumes and large bandwidths of both fine-mode and coarse-mode aerosol size distributions occurred in July and August because of biomass burning. Single-scattering albedos at 440 nm (SSA440 nm) from 0.91 to 0.94 indicated particles with relatively strong to moderate absorption. Strongly absorbing particles from biomass burning with a significant SSA wavelength dependence were found in July and August at most sites, while coarse particles in March to May were mineral dust. Absorbing aerosols were distributed more or less homogeneously throughout the region with absorption aerosol optical depths at 440 nm ˜ 0.04-0.06, but inter-site differences in the absorption Angström exponent indicate a degree of spatial heterogeneity in particle composition. The annual mean DARF was -93 ± 44 to -79 ± 39 W m-2 at the Earth's surface and ˜ -40 W m-2 at the top of the atmosphere (for the solar zenith angle range of 50 to 80°) under cloud-free conditions.

Full Text Available The knowledge of nitrogen concentration in the ocean is fundamental for the study of oceanic biogeochemical processes. The objective of this research is to estimate total inorganic nitrogen (TIN by integrating optical parameters from HJ-1 CCD image and polarization parameters from RADARSAT-2 quad-polarization image. The situ data and HJ-1 CCD, RADARSAT-2 image were acquired from Pearl River Estuary Hong Kong Seas, China in August, 2010. The four sensitive parameters, reflectance of Band 4, NDSI (Normalized Difference Spectral Index, the backscattering coefficient of HV and VH were derived as input variables to assess the TIN. A multiple regression model was established between four input variables and TIN. The result showed that the fusion of optical data and SAR data was proved to be successful in estimating TIN in sea surface, with the correlation coefficient (R2 between measured TIN and predicated TIN of 0.774, and the root mean square error (RMSE of 0.063. The optical data in combination with SAR data is promising for detecting biochemical component in sea surface.

In this work, remote sensing reflectance (Rrs) spectra of the Zhejiang coastal water in the East China Sea (ECS) were simulated by using the Hydrolight software with field data as input parameters. The seawater along the Zhejiang coast is typical Case II water with complex optical properties. A field observation was conducted in the Zhejiang coastal region in late May of 2016, and the concentration of ocean color constituents (pigment, SPM and CDOM), IOPs (absorption and backscattering coefficients) and Rrs were measured at 24 stations of 3 sections covering the turbid to clear inshore coastal waters. Referring to these ocean color field data, an ocean color model suitable for the Zhejiang coastal water was setup and applied in the Hydrolight. A set of 11 remote sensing reflectance spectra above water surface were modeled and calculated. Then, the simulated spectra were compared with the filed measurements. Finally, the spectral shape and characteristics of the remote sensing reflectance spectra were analyzed and discussed.

Organ procurement from executed prisoners in China.

Organ procurement from executed prisoners in China is internationally condemned, yet this practice continues unabated in 2014. This is despite repeated announcements from Chinese authorities that constructive measures have been undertaken to conform to accepted ethical standards. While there is unanimous agreement on the unethical nature of using organs from executed prisoners, due to its limitations on voluntary and informed consent, there is insufficient coverage of forced organ procurement from prisoners of conscience without consent. Strategies to influence positive change in China over the last few decades have failed to bring this practice to an end. While organ donation and transplantation services in China have undergone considerable structural changes in the last few years, fundamental attempts to shift practice to ethically sourced organs have floundered. In this article, we discuss the organ trade in China, reflect upon organ procurement from executed prisoners (including both capital prisoners and prisoners of conscience) and provide an overview of contradictory Chinese efforts to halt forced organ procurement from executed prisoners. Finally, we highlight current actions being taken to address this issue and offer comprehensive recommendations to bring this ethically indefensible practice to an immediate end. © Copyright 2014 The American Society of Transplantation and the American Society of Transplant Surgeons.

We determine and interpret fine particulate matter (PM2.5) concentrations in eastern China for January to December 2013 at a horizontal resolution of 6 km from aerosol optical depth (AOD) retrieved from the Korean geostationary ocean color imager (GOCI) satellite instrument. We implement a set of filters to minimize cloud contamination in GOCI AOD. Evaluation of filtered GOCI AOD with AOD from the Aerosol Robotic Network (AERONET) indicates significant agreement with mean fractional bias (MFB) in Beijing of 6.7 % and northern Taiwan of -1.2 %. We use a global chemical transport model (GEOS-Chem) to relate the total column AOD to the near-surface PM2.5. The simulated PM2.5 / AOD ratio exhibits high consistency with ground-based measurements in Taiwan (MFB = -0.52 %) and Beijing (MFB = -8.0 %). We evaluate the satellite-derived PM2.5 versus the ground-level PM2.5 in 2013 measured by the China Environmental Monitoring Center. Significant agreement is found between GOCI-derived PM2.5 and in situ observations in both annual averages (r2 = 0.66, N = 494) and monthly averages (relative RMSE = 18.3 %), indicating GOCI provides valuable data for air quality studies in Northeast Asia. The GEOS-Chem simulated chemical composition of GOCI-derived PM2.5 reveals that secondary inorganics (SO42-, NO3-, NH4+) and organic matter are the most significant components. Biofuel emissions in northern China for heating increase the concentration of organic matter in winter. The population-weighted GOCI-derived PM2.5 over eastern China for 2013 is 53.8 μg m-3, with 400 million residents in regions that exceed the Interim Target-1 of the World Health Organization.

Full Text Available Aerosol haze pollution has had a significant impact on both global climate and the regional air quality of Eastern China, which has a high proportion of high level pollution days. Statistical analyses of aerosol optical properties and direct radiative forcing at two AERONET sites (Beijing and Xuzhou were conducted from 2013 to 2016. Results indicate: (1 Haze pollution days accounted for 26% and 20% of days from 2013 to 2016 in Beijing and Xuzhou, respectively, with the highest proportions in winter; (2 The averaged aerosol optical depth (AOD at 550 nm on haze days were about 3.7 and 1.6 times greater than those on clean days in Beijing and Xuzhou, respectively. At both sites, the maximum AOD occurred in summer; (3 Hazes were dominated by fine particles at both sites. However, as compared to Xuzhou, Beijing had larger coarse mode AOD and higher percentage of small α. This data, together with an analysis of size distribution, suggests that the hazes in Beijing were more susceptible to coarse dust particles than Xuzhou; (4 During hazes in Beijing, the single scattering albedo (SSA is significantly higher when compared to clean conditions (0.874 vs. 0.843 in SSA440 nm, an increase much less evident in Xuzhou. The most noticeable differences in both SSA and the imaginary part of the complex refractive index between Beijing and Xuzhou were found in winter; (5 In Beijing, the haze radiative forcing produced an averaged cooling effect of −113.6 ± 63.7 W/m2 at the surface, whereas the averaged heating effect of 77.5 ± 49.7 W/m2 within the atmosphere was at least twice as strong as clean days. In Xuzhou, such a radiative forcing effect appeared to be much smaller and the difference between haze and clean days was insignificant. Derived from long-term observation, these findings are more significant for the improvement of our understanding of haze formation in China and the assessment of its impacts on radiative forcing of climate change than previous

China has long been regarded as a centralized society where the public has little influence on decision-making. Such a top-down management scheme is perceived as a major obstacle to address complicated environment issues. The recent public campaign in China to urge creation of a nationwide PM₂.₅ monitoring network and mitigation plan provides an unprecedented case of how the public participated and influenced policy-making in a centralized society. This paper reviews key incidents in the campaign chronologically. Here we identify information technology, public awareness of air quality's health impacts and the fact air quality affects everyone as public goods as the major factors promoting public participation. This case demonstrates that public participation can happen in a centralized, top-down society such as China. Continued environmental deterioration may stimulate similar campaigns for other issues. We anticipate this essay to be a starting point for more studies on how environmental issues stimulate incremental social change by making people involved in decision-making process, especially in societies where they are rarely able to do so.

Air pollution is one of the most important environmental problems in developing Asian countries like China. Due to huge consumption of fossil fuels and rapid increase of traffic emissions in the past decades, many regions in China have been experiencing heavy air pollution. The Yangtze River Delta (YRD) region includes the mega-city Shanghai and the well-industrialized and urbanized areas of Zhejiang Province and Jiangsu Province, with over ten large cities, such as Hangzhou, Suzhou and Nanjing. Covering only 2% land area, this region produces over 20% of China's Gross Domestic Product (GDP) which makes it the most densely populated region and one of the most polluted regions in China. For instance, there more than 60% of a year was haze days with poor visibility in Shanghai over the last few years. In the YRD region, knowledge gaps still exist in the understanding of the source and transport of air pollutants because only few measurement studies have been conducted. MAX-DOAS measurements were performed in Shanghai city center and Wujiang (border of Shanghai and Jiangsu Province) from 2010 to 2012 and in Nanjing (capital of Jiangsu Province) from April 2013. A retrieval algorithm, based on an on-line implementation of the radiative transfer code LIDORT and the optimal estimation technique, has been used to provide information on aerosol extinction vertical profiles. The total aerosol optical depths (AODs) calculated from the retrieved profiles were compared to MODIS, AERONET and local PM measurements. The aerosol information was input to LIDORT to calculate NO2 air mass factors. The retrieved tropospheric NO2 vertical column densities (VCDs) were compared to in-situ and satellite NO2 measurements.

This paper provides insights on the status of broadband optical access market and technologies in Europe and on the expected trends for the next generation optical access networks. The final target for most operators, cities or any other player is of course FTTH (Fibre To The Home) deployment although we can expect intermediate steps with copper or wireless technologies. Among the two candidate architectures for FTTH, PON (Passive Optical Network) is by far the most attractive and cost effective solution. We also demonstrate that Ethernet based optical access network is very adequate to all-IP networks without any incidence on the level of quality of service. Finally, we provide feedback from a FTTH pilot network in Colmar (France) based on Gigabit Ethernet PON technology. The interest of this pilot lies on the level of functionality required for broadband optical access networks but also on the development of new home network configurations.

Contextualizing Female Infanticide: Ming China in Early Modern European Travelogues

Directory of Open Access Journals (Sweden)

Rachana Sachdev

2010-10-01

Full Text Available One of the essential components of the early modern European response to China was an emphasis on the fabulous wealth and social organization of Chinese society. Despite their knowledge of the wide-scale abandonment and killing of newborns within the society, and despite the categorization of infanticide as a great moral sin by the early Christian church, the European travelers to China commented on infanticide dispassionately, without any moral revulsion, and continued to project an image of China as a virtual utopia for its residents. One reason for the detached descriptions of abandonment of children and infanticide in China might be the fact that conditions with regard to children in Europe were no superior to those in China and were probably far worse; the vast numbers of abandoned and dead children in Europe blunted the edge of criticism with regard to Chinese customs. Another might be that infanticide was practiced within Europe contemporaneously, even though the killing of newborn children there was practiced much more surreptitiously, and public opinion had firmed up connections among single women, illegitimacy, concealment, and murder. However, the dire social circumstances within their own countries had not prevented the Europeans from soundly criticizing and morally reproving cannibalism or infanticide in other cultures. In order to understand their acceptance of this “sinful” practice in China, we must look elsewhere.

Aerosol optical properties and direct radiative forcing based on measurements from the China Aerosol Remote Sensing Network (CARSNET in eastern China

2018-01-01

Full Text Available Aerosol pollution in eastern China is an unfortunate consequence of the region's rapid economic and industrial growth. Here, sun photometer measurements from seven sites in the Yangtze River Delta (YRD from 2011 to 2015 were used to characterize the climatology of aerosol microphysical and optical properties, calculate direct aerosol radiative forcing (DARF and classify the aerosols based on size and absorption. Bimodal size distributions were found throughout the year, but larger volumes and effective radii of fine-mode particles occurred in June and September due to hygroscopic growth and/or cloud processing. Increases in the fine-mode particles in June and September caused AOD440 nm  >  1.00 at most sites, and annual mean AOD440 nm values of 0.71–0.76 were found at the urban sites and 0.68 at the rural site. Unlike northern China, the AOD440 nm was lower in July and August (∼ 0.40–0.60 than in January and February (0.71–0.89 due to particle dispersion associated with subtropical anticyclones in summer. Low volumes and large bandwidths of both fine-mode and coarse-mode aerosol size distributions occurred in July and August because of biomass burning. Single-scattering albedos at 440 nm (SSA440 nm from 0.91 to 0.94 indicated particles with relatively strong to moderate absorption. Strongly absorbing particles from biomass burning with a significant SSA wavelength dependence were found in July and August at most sites, while coarse particles in March to May were mineral dust. Absorbing aerosols were distributed more or less homogeneously throughout the region with absorption aerosol optical depths at 440 nm  ∼  0.04–0.06, but inter-site differences in the absorption Angström exponent indicate a degree of spatial heterogeneity in particle composition. The annual mean DARF was −93 ± 44 to −79 ± 39 W m−2 at the Earth's surface and ∼ −40 W m−2 at the top of the atmosphere (for

Full Text Available This article discusses the features and mechanisms of ensuring and maintaining social and political stability in China. Analyzes the scientific theoretical foundation in the study of this phenomenon, developed by Russian and Chinese scientists. Political stability in contemporary China is understood as a precondition for effective social and economic development. The paper studied the treatment of leadership in China from different generations to tools approval of social and political stability as a way of implementing the modernization program of the political course. It has been found that maintaining the political stability of the society in modern China made possible by the harmonization of public relations, flexible national policy, economic growth, trends in socio-economic development and the use of ideological tools. The author studied the basic mechanisms of the stability of the political system of China at the present stage. It is concluded that a stable political development in contemporary China strengthens the regime and the preservation of the monopoly of the CCP to political power.

'The Asian Routes Towards the Global Information Society' and 'Towards a Strategic Planning for the Global Information Society' will be the forum themes of 'Asia Telecom 97' and 'Telecom Interactice 97' events respectively, to be held by the International Telecommunication Union (ITU) in order to further telecommunication development around the world. International telecommunications network affects our life by keeping us in touch, bringing us world news and underpinning the global economy. Global tele-economy, global information infrastructure, global information society terms are more and more used to indicate the evolution towards an information- driven world where the access to information, communication and technologies is essential to the economic and social development in every country. Telecommunication industry can strongly contribute to this evolution together with broadcasting and computer industry, and fiber optic communications are expected to continue to grow up and share a relevant part of the total telecom market. In 1995 telecom market shown a 3.8 percent worldwide investment growth reaching a 545 billion value. According to 'Kessler Marketing Intelligence (KMI) Corp.' analysis of fiberoptics and multimedia market the amount of cabled fiber installed in U.S. will be around 11 million fiber-km in 1997 and 15 million fiber-km are predicted in the year 2000. Between 1995 and 1998 the undersea industry is estimated to deal with 13.9 billion as additional undersea cable systems investment in the global telecom network. In China beside satellite telecom stations and digital microwave systems 22 fiber optic backbones have been realized and another 23 systems are expected to be built in the Ninth Five-Year National Plan (1996 to approximately 2000) with a total length of nearly 30,000 sheat-km. The study, Fiber and Fiberoptic Cable Markets in China, recently released by KMI Corp. shows that fiber optic cable installation by MPT and other network operators

Li, M; Wei, L; Liu, H; Tang, L

2009-03-01

Nursing research in Mainland China is divided into two parts: domestic nursing research, comprising all publications in Chinese; and international nursing research, comprising all publications in English. Domestic nursing research has been developing rapidly, demonstrated by the increase in new national or regional journals and publications. However, little is known about the extent of international research. To outline the development of international nursing research publications in Mainland China and to provide suggestions for future development. All of the papers were retrieved from PubMed. The key search phase was 'China or P.R.China NOT Hong Kong NOT Taiwan NOT Macao [AD]', with the limits of 'English', 'nursing journals' as well as the published date up to '2007/09/30'. PubMed recorded 57 English papers that were originally conducted in Mainland China during the search period from 1989 to 30 September 2007. Thirty-seven of the total 57 (65%) publications were contributed by Beijing, Shanghai and Hubei. Forty-four of the 57 publications were conducted with collaborators from Hong Kong, the USA, the UK and Canada. Thirteen publications were funded by international societies, while only three were funded by the Chinese government. The research topics mainly focused on clinical research, nursing education and nursing management. This study indicates that international nursing research has been growing slowly in Mainland China along with provincial variations. The suggestions to improve nursing research include the reform of nursing education, the enhancement of the collaboration with the international societies and the establishment of research priorities.

Defining migration and its health impact in China.

Mou, J; Griffiths, S M; Fong, H F; Dawes, M G

2015-10-01

The scale and rapid expansion of urbanization resulting from socio-economic transformation in China at the beginning of the 21st century has accelerated rural-urban migration. Public health concerns from this increasing internal population mobility are now receiving attention from researchers. The health problems from internal migration pose particular demands on healthcare systems and relate to its demographic characteristics, with many younger and older people being left behind in the rural countryside. A review of literature, census, policy reports, government documents and media was undertaken to look at the classification system and health characteristics of China's internal migrants. It suggests that public health bears the consequences of political and economic decisions made elsewhere in society. Copyright © 2014 The Royal Society for Public Health. Published by Elsevier Ltd.

Shock Waves in Condensed Matter

1986-01-01

The Fourth American Physical Society Topical Conference on Shock Waves in Condensed Matter was held in Spokane, Washington, July 22-25, 1985. Two hundred and fifty scientists and engineers representing thirteen countries registered at the conference. The countries represented included the United States of America, Australia, Canada, The People's Repub­ lic of China, France, India, Israel, Japan, Republic of China (Taiwan), United Kingdom, U. S. S. R, Switzerland and West Germany. One hundred and sixty-two technical papers, cov­ ering recent developments in shock wave and high pressure physics, were presented. All of the abstracts have been published in the September 1985 issue of the Bulletin of the American Physical Society. The topical conferences, held every two years since 1979, have become the principal forum for shock wave studies in condensed materials. Both formal and informal technical discussions regarding recent developments conveyed a sense of excitement. Consistent with the past conferences, th...

The Relationship Between Core Members' Social Capital and Perceived and Externally Evaluated Prestige and Cooperation Among HIV/AIDS-Related Civil Society Organizations in China.

Wang, Danni; Xu, Xiaoru; Mei, Guangliang; Ma, Ying; Chen, Ren; Qin, Xia; Hu, Zhi

2017-03-01

The purpose of this study was to investigate whether the core members' social capital was associated with individually perceived and externally evaluated prestige and cooperation among the HIV/AIDS-related civil society organizations (CSOs). To accomplish this, a cross-sectional study using multistage sampling was carried out in eight provinces of China. Data were collected from the 327 core members via questionnaires and self-evaluated performance of the respondents were evaluated and measured. The interviews were conducted with all core members and the supervisory staff of the local Centers for Disease Control and Prevention. Multivariate logistic regression analysis indicated that social support (adjusted odds ratio [a OR] = 1.87) and organizational commitment (a OR = 1.57) were significantly associated with a higher odds of prestige performance in self-evaluation. Furthermore, social support (a OR = 1.65), trust (a OR = 1.33), and organizational commitment (a OR = 1.52) were significantly correlated with cooperation performance. Trust was positively associated with the cooperation performance on external evaluation. These findings may provide a new perspective on challenges that the CSOs face in response to a growing HIV/AIDS epidemic in China. Social capital may increase performance and accelerate organizational growth, ultimately improving HIV/AIDS prevention and care.

The Pursuit of Happiness in China: Individualism, Collectivism, and Subjective Well-Being during China's Economic and Social Transformation*

Science.gov (United States)

Steele, Liza G; Lynch, Scott M

2013-11-01

This paper examines the consequences of China's dramatic socioeconomic and political transformations for individual subjective well-being (SWB) from 1990 to 2007. Although many still consider China to be a collectivist country, and some scholars have argued that collectivist factors would be important predictors of individual well-being in such a context, our analysis demonstrates that the Chinese are increasingly prioritizing individualist factors in assessments of their own happiness and life satisfaction thus substantiating descriptions of their society as increasingly individualistic. While the vast majority of quality of life studies have focused on Westerners, this study contributes findings from the unique cultural context of China. Moreover, concentration on this particular period in Chinese history offers insight into the relationship between SWB and rapid socioeconomic and political change.

Optical biosensors represent the most common type of biosensor. Here we provide a brief classification, a description of underlying principles of operation and their bioanalytical applications. The main focus is placed on the most widely used optical biosensors which are surface plasmon resonance (SPR)-based biosensors including SPR imaging and localized SPR. In addition, other optical biosensor systems are described, such as evanescent wave fluorescence and bioluminescent optical fibre biosensors, as well as interferometric, ellipsometric and reflectometric interference spectroscopy and surface-enhanced Raman scattering biosensors. The optical biosensors discussed here allow the sensitive and selective detection of a wide range of analytes including viruses, toxins, drugs, antibodies, tumour biomarkers and tumour cells. © 2016 The Author(s).

2016-11-24

To analyze the discourse right construction of China's medical aid to Africa, so as to provide evidences for improving the effect and sustainable development of China's medical aid to Africa. The documents of the discourse right that China constructed in the medical aid to Africa were selected at different periods as discourse samples. The achievement and deficiency were analyzed from four aspects, namely confident, charismatic, influential, and dominant. China's medical team made much in the discourse right construction in their aid to Africa, but some China's medical team members were still too cautious and too low-key. China's medical team gained the trust of the people of Africa, but the language communication difficulties still hampered in China's medical aid to Africa. Chinese medical team were widely praised by the African society, but in the west, some African media, even China's media still neglected to report China's doctors. China's international discourse right were greatly improved, but western countries still dominated the public opinion. China should refer to the actual situation of medical aid to Africa to strengthen the construction of discourse right.

AHP 28: Review: China's Environmental Challenges

Bill Bleisch

2013-12-01

Full Text Available Judith Shapiro's latest ambitious work picks up the story of modern China's checkered relationship with the environment at approximately the point where her previous study, Mao's War Against Nature (2001, left off. 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.1 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 China seeks to address them, are now widely recognized as having major impacts on the entire planet. Chinese demand has become a major factor in the pricing of the world's natural resources, while pollution from Chinese sources, particularly emissions of CO2 and other climate changing gasses, are having global consequences.

China building energy consumption: Situation, challenges and corresponding measures

Cai, W.G.; Wu, Y.; Zhong, Y.; Ren, H.

2009-01-01

As one of the biggest parts of total national energy consumption (TNEC), building energy consumption (BEC) catches public eyes and has been regarded as a crucial problem of the current society. For the past 20 years, BEC in china has been increasing at a high speed. To curb the rapid growing of BEC, china has enforced and implemented a series of policies. These include enforcing BEC constraints on new building projects, promoting more environment friendly building designs, establishing a more sophisticated legislation for building energy conservation, and increasing the total budget in the area of BEC control. This article analyzed china BEC situation and the challenges. As the main point, the measures required by China government to improve building energy efficiency were introduced as well.

Loess deposits since early Pleistocene in northeast China and implications for desert evolution in east China

2018-04-01

Loess deposits and deserts are regarded as coupled geological systems and loess deposits on the periphery of deserts can often be used to reconstruct desert evolution. Previous studies of desert evolution in Asia are mainly concentrated in northwest China and the China Loess Plateau, and little is known about long-term desert evolution in east China. In this study, we selected the Sishijiazi loess section in the Chifeng area in northeast China to study the long-term evolution of the desert in east China. A high-resolution magnetostratigraphy combined with optically stimulated luminescence dating indicated that the age of the section base is approximately 1.02 Ma. The Brunhes-Matuyama boundary is at the depth of 39.8 m in loess unit L8, and the upper boundary of the Jaramillo Subchron is at the depth of 60.8 m in paleosol S10. The results of grain-size analysis indicate a coarsening grain-size trend in the past 1.0 Ma. In addition, based on grain-size variations, the desert evolution in east China since ∼1.0 Ma can be divided into three stages: stability from 1.0 to 0.8 Ma, desert recession from 0.8 to 0.5 Ma, and gradual expansion since 0.5 Ma. Our results further indicate that the evolution of desert in east China was mainly controlled by changes in global ice volume, and that the uplift of the Tibetan Plateau may have had an additional effect.

In 2016, the authors published their concept study and suggestions for a 12-m telescope optical system. This article presents the authors' further research and some new results. Considering that this telescope should be a general-purpose telescope for a wide range of scientific goals and could be used for frontier scientific research in the future, the authors studied and designed a variety of 12-m telescope optical systems for comparison and final decision-making. In general, we still adopt our previous configuration, but the Nasmyth and prime-focus corrector systems have been greatly improved. In this article, the adaptive optics is given special attention. Ground-layer adaptive optics (GLAO) is adopted. It has a 14-arcmin field of view. The secondary mirror is used as the adaptive optical deformable mirror. Obviously, not all the optical systems in this telescope configuration will be used or constructed at the same stage. Some will be for the future and some are meant for research rather than for construction.

Since Xi Jinping invoked"The China Dream"as a key concept in November 2012,this phrase has come to dominate discussions of China’s future.This paper will examine the China dream phenomenon first by placing it in the context of debates that have been raging in Chinese civil society over the past few years.It will analyze the works of20 prominent"China dreamers"in terms of debates over the proper relationship between(1)politics and economics,(2)equality and hierarchy,(3)civilization and civility,and(4)nationalism and statism.The other main context for the China dream concept is the American dream.While it is common to dismiss the American dream as crass materialism,this essay will examine how it stresses the complementary ideals of freedom and equality.More importantly,it will examine how the American dream has been used as a critical tool to comment on problems in the United States,and relate this to examples in the PRC where the China dream is being used as a critical tool as well.

Total Lightning Flash Activity Response to Aerosol over China Area

Directory of Open Access Journals (Sweden)

Pengguo Zhao

2017-01-01

Full Text Available Twelve years of measurements of aerosol optical depth (AOD, cloud fraction, cloud top height, ice cloud optical thickness and lightning flash density from 2001 to 2012 have been analyzed to investigate the effect of aerosols on electrical activity over an area of China. The results show that increasing aerosol loading inspires the convective intensity, and then increases the lightning flash density. The spatial distribution of the correlation between aerosol loading and electrical activity shows a remarkable regional difference over China. The high-correlation regions embody the positive aerosol microphysical effect on the intensity of the electrical activity, while the large-scale processes may play the main role in convection development and producing lightning in low-correlation regions.

Full text: Quantum optics in Australia has been an active research field for some years. I shall focus on recent developments in quantum and atom optics. Generally, the field as a whole is becoming more and more diverse, as technological developments drive experiments into new areas, and theorists either attempt to explain the new features, or else develop models for even more exotic ideas. The recent developments include quantum solitons, quantum computing, Bose-Einstein condensation, atom lasers, quantum cryptography, and novel tests of quantum mechanics. The talk will briefly cover current progress and outstanding problems in each of these areas. Copyright (1999) Australian Optical Society.

Evaluation of the MODIS C6 Aerosol Optical Depth Products over Chongqing, China

Directory of Open Access Journals (Sweden)

Guangming Shi

2017-11-01

Full Text Available The Moderate Resolution Imaging Spectroradiometer (MODIS Collection 6 (C6 aerosol optical depth (AOD products from the 10/3 km Dark Target (DT and Deep Blue (DB algorithms are firstly evaluated using ground observed AODs by the sun photometer in Chongqing, a mountainous mega-city in southwest China. The validation results show that MODIS AODs from 10/3 km DT algorithm are comparable with those of the sun photometer, although there are slight overestimations. However, the DB algorithm substantially underestimates MODIS AODs when comparing with those of the sun photometer. Error analyses imply that the bias of surface reflectance estimation is the main error source for both algorithms. The cloud screening scheme of the DT algorithm is more effective than the DB algorithm. The cloud vicinity effect should be considered in the quality control processes for both of the algorithms. A sensitivity test suggests that in complex terrain area, like Chongqing, the collocation method in the validation of satellite products should be carefully selected according to local circumstances. When comparing the monthly mean AODs of MODIS products with sun photometer observations, it shows that the Terra MODIS AOD products are valid to represent the mean statuses in summer and autumn, but the monthly mean of Aqua MODIS AODs are limited in Chongqing.

Managing agricultural nutrients to provide a safe and secure food supply while protecting the environment remains one of the great challenges for the 21st century. The fourth International Nutrient Management Symposium (INMS), held in 2011 at the University of Delaware, addressed these issues via presentations, panel sessions, and field tours focused on latest technologies and policies available to increase nutrient use efficiency. Participants from the United States, Europe, Canada, and China discussed global trends and challenges, balancing food security and the environment in countries with struggling and emerging economics, nutrient management and transport at the catchment scale, new technologies for managing fertilizer and manure nutrients, and adaptive nutrient management practices for farm to watershed scales. A particular area of interest at the fourth INMS was nutrient management progress and challenges in China over the past 40 years. China's food security challenges and rapidly growing economy have led to major advances in agricultural production systems but also created severe nutrient pollution problems. This special collection of papers from the fourth INMS gives an overview of the remarkable progress China has made in nutrient management and highlights major challenges and changes in agri-environmental policies and practices needed today. Lessons learned in China are of value to both developing and developed countries facing the common task of providing adequate food for an expanding world population, while protecting air and water quality and restoring damaged ecosystems.

This paper compares water resource policies and management practices in China and Denmark. It takes two vulnerable water ecosystems as case studies: Baiyangdian wetland in China and Mariager fjord in Denmark. Based on the theories of the commons, this article explores the similarities...... due to the complicated administrative structure in China and clearer goals and better resources in Denmark. Denmark has also accomplished a large degree of environmental policy integration (EPI), which is not the case in China. But China has recently put environmental concerns high on the agenda...... and differences between the two ecosystems in terms of ecosystem characteristics, historical and cultural backgrounds of these societies, the technologies affecting the ecosystems and also how the ecosystems have been seen at different times as well as the existence of property rights through time.

Wherever We Find Friends there Begins a New Life: Tagore and China

Full Text Available Tagore made a deep impression upon the Chinese culture and society. In 1923, the Jiangxue she 講學社 (Beijing Lecture Association invited Rabindranath Tagore to deliver a series of talks. The Jiangxue she Association was established in September 1920 and represented one of the many institutions that came to life in China during the May Fourth Movement. Since then, almost all of his works in English have been translated into Chinese. He came to China just when the latter was beginning her Renaissance and his visit certainly gave a great impetus to this new movement. His poems of Stray Birds and The Crescent Moon have created new styles of prosody in the new Chinese poetry. A Crescent Moon Society (for poetry and a Crescent Moon magazine were started immediately after this event by Hu Shi 胡适 (Hu 2002: 90. During his visit, Tagore raised two basic questions, one about the relation between tradition and modernity, and the other about the usual identification of modernisation with Westernisation. Since the May Fourth Movement, China has also been concerned with these questions and Chinese intellectuals have come out with different answers. These questions, however, were important not only for China but for India as well. Such debates and the revaluation of various answers represented the most important condition for a consolidation of new ideologies, which formed a political basis for the changing societies of both countries.

Full Text Available The papers in this issue of Cross-Currents grew out of a Berkeley workshop with the same title. They may not have much in common in terms of genre, discipline, project, or objective. Yet they share an attention to the material aspects of China, both in “China proper” and in the Chinese borderlands, including issues of resources, environment, and ecology in studies of history, politics, society, and economy. The papers, in short, seek to invest a certain agency in environmental factors. They also seek to demonstrate the reward of such an approach. . . .

Importation of yellow fever into China: assessing travel patterns.

Wilder-Smith, Annelies; Leong, W Y

2017-07-01

Rapid increase in trade and a growing air passenger market encourages high travel volume between the regions associated with increasing risks of such importations including China. Eleven Chinese workers infected during the 2016 yellow fever (YF) outbreak in Angola imported YF into China highlighting the potential for spread into Asia. Using outbound and inbound travel data, we assessed travel patterns from and to YF endemic countries in relation to China. Among YF endemic countries, Angola has the second highest number of travellers into China and also receives the second highest number of Chinese visitors. We estimated that China needs around half a million YF vaccine doses to cover their population travelling to YF endemic countries. The recent importation cases into China also unmasked the low YF vaccination coverage among Chinese travellers and workers to Angola, indicating the need to ensure better adherence to the International Health Regulations. © International Society of Travel Medicine, 2017..

Hands-on optics: an informal science education initiative

Science.gov (United States)

Johnson, Anthony M.; Pompea, Stephen M.; Arthurs, Eugene G.; Walker, Constance E.; Sparks, Robert T.

2007-09-01

The project is collaboration between two scientific societies, the Optical Society of America (OSA) and SPIE - The International Society for Optical Engineering and the National Optical Astronomy Observatory (NOAO). The program is designed to bring science education enrichment to thousands of underrepresented middle school students in more than ten states, including female and minority students, who typically have not been the beneficiaries of science and engineering resources and investments. HOO provides each teacher with up to six activity modules, each containing enough materials for up to 30 students to participate in 6-8 hours of hands-on optics-related activities. Sample activities, developed by education specialists at NOAO, include building kaleidoscopes and telescopes, communicating with a beam of light, and a hit-the-target laser beam challenge. Teachers engage in two days of training and, where possible, are partnered with a local optics professional (drawn from the local rosters of SPIE and OSA members) who volunteers to spend time with the teacher and students as they explore the module activities. Through these activities, students gain experience and understanding of optics principles, as well as learning the basics of inquiry, critical thinking, and problem solving skills involving optics, and how optics interfaces with other disciplines. While the modules were designed for use in informal after- school or weekend sessions, the number of venues has expanded to large and small science centers, Boys and Girls Clubs, Girl Scouts, summer camps, family workshops, and use in the classroom.

2012-03-01

The U.S. government has brought a new trade case against China over rare earth elements (REE) as well as tungsten and molybdenum, President Barack Obama announced on 13 March. Japan and the European Union also have taken similar actions against China about REEs, which are a group of 17 chemically similar metallic elements that are used in a variety of electronic, optical, magnetic, and catalytic applications. REEs are plentiful in the Earth's crust, although China currently has about 37% of the world's reserves and accounts for more than 95% of the world's production of the elements, according to the British Geological Survey. The United States has requested consultations with China at the World Trade Organization (WTO) concerning "China's unfair export restraints on rare earths, as well as tungsten and molybdenum," the Office of the United States Trade Representative announced in a 13 March statement.

Ethics teaching is a relatively new area of medical education in China, with ethics curricula at different levels of development. This study examined ethics education at three medical schools in China to understand their curricular content, teaching and learning methods, forms of assessments, changes over time, and what changes are needed for further improvement. We used student and faculty surveys to obtain information about the ethics courses' content, teaching methods, and revisions over time. The surveys also included five realistic cases and asked participants whether each would be appropriate to use for discussion in ethics courses. Students rated the cases on a scale and gave written comments. Finally, participants were asked to indicate how much they would agree with the statement that medical professionalism is about putting the interests of patients and society above one's own. There were both similarities and differences among these schools with regard to course topics, teaching and assessment methods, and course faculty compositions, suggesting their courses are at different levels of development. Areas of improvement for the schools' courses were identified based on this study's findings and available literature. A model of the evolution of medical ethics education in China was proposed to guide reform in medical ethics instruction in China. Analysis identified characteristics of appropriate cases and participants' attitudes toward the ideal of professionalism. We conclude that the development of medical ethics education in China is promising while much improvement is needed. In addition, ethics education is not confined to the walls of medical schools; the society at large can have significant influence on the formation of students' professional values.

Improving fiber-optic laser beam delivery by incorporating GRADIUM optics

International Nuclear Information System (INIS)

Hunter, B.V.; Leong, K.H.

1997-01-01

The performance of a fiber-optic laser beam delivery system strongly depends on the fiber and the optics used to image the fiber face on the workpiece. We have compared off-the-shelf homogenous (BK7) and GRADIUM (axial-gradient) singlets to determine what improvement the GRADIUM offers in practice to the typical laser user. The realized benefit for this application, although significant, is much smaller than would be realized by a conventional imaging application. The figure of merit for laser-based materials processing is the 86% energy-enclosure radius, which is not directly supported by commerical ray-tracing software. Therefore empirical rules of thumb are presented to understand when GRADIUM (or any other well-corrected optics) will yield meaningful improvement to the beam delivery system. copyright 1997 Optical Society of America

Political repression, civil society and the politics of responding to AIDS in the BRICS nations.

Gómez, Eduardo J; Harris, Joseph

2016-02-01

The policy responses to human immunodeficiency virus/acquired immune deficiency syndrome (AIDS) in the Brazil, Russia, India, China and South Africa (BRICS) nations have played out amid radically different political environments that have shaped state-civil society relations in critical ways. In contrasting these different environments, this article offers the first comparison of the policy response to AIDS in the BRICS nations and seeks to understand the way in which political context matters for conditioning the response to a major epidemic. Using a comparative historical approach, we find that while collaborative state-civil society relations have produced an aggressive response and successful outcomes in Brazil, democratic openness and state-civil society engagement has not necessarily correlated with an aggressive response or better outcomes in the other cases. Response to the epidemic has been worst by far in democratic South Africa, followed by Russia, where in the former, denialism and antagonistic state-civil society relations fuelled a delayed response and proved extremely costly in terms of human lives. In Russia, a lack of civil societal opportunity for mobilization and non-governmental organization (NGO) growth, political centralization and the state's unwillingness to work with NGOs led to an ineffective government response. Top-down bureaucratic rule and a reluctance to fully engage civil society in democratic India substantially delayed the state's efforts to engage in a successful partnership with NGOs. Nevertheless, China has done surprisingly well, in spite of its repressive approach and narrow engagement with civil society. And in all cases, we find the relationship between state and civil society to be evolving over time in important ways. These findings suggest the need for more research on the links between democratic openness, political repression and policy responses to epidemics. © The Author 2015.

University Students' Views on Political Influences and the Status of Law in Post-Reform China: A Moderation and Mediation Analysis.

Science.gov (United States)

Jiang, Guoping; Lo, T Wing

2016-07-01

Scholars categorize societies into "rule of man" societies, "rule by law" societies, and "rule of law" societies on the basis of a status of law. After 1978, China's leaders invoked law as an alternative to the arbitrariness of the Cultural Revolution. In this study, we used quantitative methods to explore university students' views on the status of law in post-reform China. Surveys were conducted in three national universities located in different regions of China. Responses from university students show that their perceptions of well-developed legislation and perceptions of the publicity of law are associated with their perceptions of equality before the law, which could be the consequence of a "rule of law" system. However, the study found that university students are of the view that the political nature of legislation and interference in law enforcement moderate the relationship between legislation and equality before the law. The political nature of legislation also moderates the mediation effect of interference in law enforcement between law publicity and equality before the law. As such, the article concludes that although university students are no longer primary movers in China's social and political development after the Tiananmen incident, they are still knowledgeable if not critical about the status of law and its political implications. © The Author(s) 2015.

The author is referring to documents such as the ANS Bylaws and Rules, which have been made available to almost every existing nuclear society in the world. He remembers working with groups from Russia, Europe, China, Japan, Brazil, France, Germany, and others when they sought the experience of ANS in establishing a society. Financial planning guides are available for meetings, international conferences, technical expositions, and teacher workshops. Periodically, the ANS publishes position papers on the uses and handling of fuel materials and other publications helpful to public relations and teacher training courses. A few have had distributions in the hundreds of thousands, and one went as high as 750,000. Some of these have been translated in part into Spanish, French, Portuguese, and Japanese. Nuclear Standards are developed by a series of ANS committees consisting of about 1000 experts--the largest technical operation of ANS. Buyers guides and directories are very helpful in promoting the commerce in the nuclear industry. The Utility Directory covers utilities all over the globe. Radwaste Solutions, the new name for the former Radwaste Magazine, covers the efforts made by all sectors--private, government, and utility--to deal with radioactive waste. In the author's opinion, the one area in which all societies are weak is in interfacing with the International Atomic Energy Agency (IAEA). Since his retirement 9 yr ago, he has become much more aware of the IAEA as a news and technical information source. The ANS is trying to be more aware of what the IAEA is doing for everyone

Full Text Available The Paris Climate Change Conference was successfully concluded with the Paris Agreement, which is a milestone for the world in collectively combating climate change. By participating in IPCC assessments and conducting national climate change assessments, China has been increasing its understanding of the issue. For the first time, China's top leader attended the Conference of the Parties, which indicates the acknowledgement of the rationality and necessity of climate change response by China at different levels. Moreover, this participation reflects China's commitment to including climate change in its ecology improvement program and pursuing a low-carbon society and economy. In order to ensure the success of the Paris Conference, China has contributed significantly. China's constructive participation in global governance shows that China is a responsible power. These principles such as the creation of a future of win–win cooperation with each country contributing to the best of its ability; a future of the rule of law, fairness, and justice; and a future of inclusiveness, mutual learning, and common development will serve as China's guidelines in its efforts to facilitate the implementation of the Paris Agreement and participate in the design of international systems.

The politics of China studies in South Korea: A critical examination of South Korean historiography of modern China since 1945

Institute of Scientific and Technical Information of China (English)

Dongyoun HWANG

2012-01-01

This paper argues that the South Korean scholarship on modem Chinese history since 1945 can be characterized as apolitical with its objectivism,positivism,liberalism,and anti-communist nationalism.This characteristic is a product of not only the Cold War and the military regimes of South Korea but also the political orientation and stance of the senior historians who played an initial and decisive role in determining the goal,direc tion,and research methods of South Korean studies concerning modem China.The SouthKorean perspective they promoted usually meant the study of liberal,apolitical topics in Chinese history from a nationalist perspective without any political/ideological influences.The utility of modern Chinese history has mainly lain in helping to construct an anti-socialist,modern Korean nation-state through modernization.South Korean historians of modem China,the paper argues,have not been able to induce a meaningful,broad discussion of critical historical issues in modem China as they might pertain to South Korean society,thus failing to utilize them to help challenge and transform the undemocratic South Korean society and regimes.Hence,the future success of new academic undertakings since the 1990s by South Korean historians will be determined by whether or not they are able to make a radical break from the previous scholarship,in particular,from its objectivism and nationalism.

Preservice teachers in primary education should be well equipped to meet the challenges of teaching primary science effectively in 21century. The purpose of this research was to describe the projects for the implementation of Science-Technology-Society (STS) approach in Basic Concept of Natural Science course as application of optical and electrical instruments’ material by the preservice teachers in Elementary Schools Teacher Education Program. One of the reasons is the lack of preservice teachers’ ability in making projects for application of STS approach and optical and electrical instruments’ material in Basic Concept of Natural Science course. This research applied descriptive method. The instrument of the research was the researcher himself. The data were gathered through observation and documentation. Based on the results of the research, it was figured out that preservice teachers, in groups, were creatively and successful to make the projects of optical and electrical instruments assigned such as projector and doorbell. It was suggested that the construction of the instruments should be better (fixed and strong structure) and more attractive for both instruments, and used strong light source, high quality images, and it could use speaker box for projector, power battery, and heat sink for electrical instruments.

We propose and demonstrate a novel scheme, which enables all-optical virtual private network (VPN) and all-optical optical network units (ONUs) inter-communications in optical orthogonal frequency-division multiplexing-based passive optical network (OFDM-PON) system using the subcarrier bands allocation for the first time (to our knowledge). We consider the intra-VPN and inter-VPN communications which correspond to two different cases: VPN communication among ONUs in one group and in different groups. The proposed scheme can provide the enhanced security and a more flexible configuration for VPN users compared to the VPN in WDM-PON or TDM-PON systems. The all-optical VPN and inter-ONU communications at 10-Gbit/s with 16 quadrature amplitude modulation (16 QAM) for the proposed optical OFDM-PON system are demonstrated. These results verify that the proposed scheme is feasible. © 2011 Optical Society of America

The current situations of thermal spraying materials in China are described in this paper.The thermal spraying technology in China has a great progress over tens of years. More than one hundred varieties of material products serve thermal spraying producing now. They belong to three kinds, powders,wires and rods. Technologies for producing alloy, ceramic and composite powders, alloy and cored wires,and oxide ceramic rods are applied to large-scale production. Many research and development works on advanced materials for thermal spraying are carrying out recent years. They show that the general tendencies of thermal spraying materials in China are composite or low-impurity component, ultrafine or nanosized microstructure, high properties, and specialized and systematized applications. Thermal spraying materials have great prospects with the development of saving society in China.

Diaphorina citri (Asian citrus psyllid; ACP) transmits 'Candidatus Liberibacter asiaticus' associated with citrus Huanglongbing (HLB). ACP has been reported in 11 provinces/regions in China, yet its population diversity remains unclear. In this study, we evaluated ACP population diversity in China using representative whole mitochondrial genome (mitogenome) sequences. Additional mitogenome sequences outside China were also acquired and evaluated. The sizes of the 27 ACP mitogenome sequences ranged from 14 986 to 15 030 bp. Along with three previously published mitogenome sequences, the 30 sequences formed three major mitochondrial groups (MGs): MG1, present in southwestern China and occurring at elevations above 1000 m; MG2, present in southeastern China and Southeast Asia (Cambodia, Indonesia, Malaysia, and Vietnam) and occurring at elevations below 180 m; and MG3, present in the USA and Pakistan. Single nucleotide polymorphisms in five genes (cox2, atp8, nad3, nad1 and rrnL) contributed mostly in the ACP diversity. Among these genes, rrnL had the most variation. Mitogenome sequences analyses revealed two major phylogenetic groups of ACP present in China as well as a possible unique group present currently in Pakistan and the USA. The information could have significant implications for current ACP control and HLB management. © 2018 Society of Chemical Industry. © 2018 Society of Chemical Industry.

Medical missionaries to China: the Jesuits.

Fu, Louis

2011-05-01

The 15th and 16th centuries saw a religious revival in Europe and an increased interest in church missions. With geographical discoveries supported by strong monarchies in Spain, Portugal and later France, Catholic missions and in particular the Society of Jesus resumed the spread of Christianity to China. Convinced that it was wise policy to address themselves to the most influential upper classes, the Jesuits under the leadership of Father Matteo Ricci became friendly with the aristocrats and the intelligentsia. The Jesuits introduced Western scientific ideas into China and even practised medicine. Between periods of adversity and persecutions, Chinese emperors who valued them for their scientific expertise generally tolerated their missionary activities. Any lasting influence on Chinese culture was limited.

Xu, Junfang; Wang, Jian; Wimo, Anders; Qiu, Chengxuan

2016-05-11

Mental disorders represent a major contributor to disease burden worldwide. We sought to quantify the national economic burden of mental disorders in China. We used a prevalence-based, bottom-up approach to estimate the economic costs of mental disorders in 2005-2013 in China. Prevalence data were derived from a national survey. Cost data were derived from the electronic health records of two psychiatric hospitals that consisted of 25,289 outpatients (10%) and inpatients (90%) who were diagnosed with a mental disorder. Cost items included direct medical costs, direct non-medical costs, and indirect costs. The total annual costs of mental disorders in China increased from $1,094.8 in 2005 to $3,665.4 in 2013 for individual patients, and from $21.0 billion to $88.8 billion for the whole society. The total costs of mental disorders in 2013 accounted for more than 15% of the total health expenditure in China, and 1.1% of China's gross domestic product. If the needs of the professional care for all patients with mental illnesses were fully met, the potential economic costs would have been almost five times higher than the actual estimated costs. Mental disorders imposed a huge economic burden on individuals and the society in China. A nation-wide strategic action plan for preventing mental disorders and promoting mental health and well-being is in urgent need to reduce the individual and societal costs of mental illnesses.

Climatic effects of air pollutants over china: A review

Science.gov (United States)

Liao, Hong; Chang, Wenyuan; Yang, Yang

2015-01-01

Tropospheric ozone (O3) and aerosols are major air pollutants in the atmosphere. They have also made significant contributions to radiative forcing of climate since preindustrial times. With its rapid economic development, concentrations of air pollutants are relatively high in China; hence, quantifying the role of air pollutants in China in regional climate change is especially important. This review summarizes existing knowledge with regard to impacts of air pollutants on climate change in China and defines critical gaps needed to reduce the associated uncertainties. Measured monthly, seasonal, and annual mean surface-layer concentrations of O3 and aerosols over China are compiled in this work, with the aim to show the magnitude of concentrations of O3 and aerosols over China and to provide datasets for evaluation of model results in future studies. Ground-based and satellite measurements of O3 column burden and aerosol optical properties, as well as model estimates of radiative forcing by tropospheric O3 and aerosols are summarized. We also review regional and global modeling studies that have investigated climate change driven by tropospheric O3 and/or aerosols in China; the predicted sign and magnitude of the responses in temperature and precipitation to O3/aerosol forcings are presented. Based on this review, key priorities for future research on the climatic effects of air pollutants in China are highlighted.

2018-01-01

This study performed two phases of analysis to shed light on the performance and thematic evolution of China's quantum cryptography (QC) research. First, large-scale research publication metadata derived from QC research published from 2001-2017 was used to examine the research performance of China relative to that of global peers using established quantitative and qualitative measures. Second, this study identified the thematic evolution of China's QC research using co-word cluster network analysis, a computational science mapping technique. The results from the first phase indicate that over the past 17 years, China's performance has evolved dramatically, placing it in a leading position. Among the most significant findings is the exponential rate at which all of China's performance indicators (i.e., Publication Frequency, citation score, H-index) are growing. China's H-index (a normalized indicator) has surpassed all other countries' over the last several years. The second phase of analysis shows how China's main research focus has shifted among several QC themes, including quantum-key-distribution, photon-optical communication, network protocols, and quantum entanglement with an emphasis on applied research. Several themes were observed across time periods (e.g., photons, quantum-key-distribution, secret-messages, quantum-optics, quantum-signatures); some themes disappeared over time (e.g., computer-networks, attack-strategies, bell-state, polarization-state), while others emerged more recently (e.g., quantum-entanglement, decoy-state, unitary-operation). Findings from the first phase of analysis provide empirical evidence that China has emerged as the global driving force in QC. Considering China is the premier driving force in global QC research, findings from the second phase of analysis provide an understanding of China's QC research themes, which can provide clarity into how QC technologies might take shape.

Tao, Jun; Zhang, Leiming; Cao, Junji; Zhang, Renjian

2017-08-01

To obtain a thorough knowledge of PM2. 5 chemical composition and its impact on aerosol optical properties across China, existing field studies conducted after the year 2000 are reviewed and summarized in terms of geographical, interannual and seasonal distributions. Annual PM2. 5 was up to 6 times the National Ambient Air Quality Standards (NAAQS) in some megacities in northern China. Annual PM2. 5 was higher in northern than southern cities, and higher in inland than coastal cities. In a few cities with data longer than a decade, PM2. 5 showed a slight decrease only in the second half of the past decade, while carbonaceous aerosols decreased, sulfate (SO42-) and ammonium (NH4+) remained at high levels, and nitrate (NO3-) increased. The highest seasonal averages of PM2. 5 and its major chemical components were typically observed in the cold seasons. Annual average contributions of secondary inorganic aerosols to PM2. 5 ranged from 25 to 48 %, and those of carbonaceous aerosols ranged from 23 to 47 %, both with higher contributions in southern regions due to the frequent dust events in northern China. Source apportionment analysis identified secondary inorganic aerosols, coal combustion and traffic emission as the top three source factors contributing to PM2. 5 mass in most Chinese cities, and the sum of these three source factors explained 44 to 82 % of PM2. 5 mass on annual average across China. Biomass emission in most cities, industrial emission in industrial cities, dust emission in northern cities and ship emission in coastal cities are other major source factors, each of which contributed 7-27 % to PM2. 5 mass in applicable cities. The geographical pattern of scattering coefficient (bsp) was similar to that of PM2. 5, and that of aerosol absorption coefficient (bap) was determined by elemental carbon (EC) mass concentration and its coating. bsp in ambient condition of relative humidity (RH) = 80 % can be amplified by about 1.8 times that under dry conditions

Optical actuation of micromechanical components

Electromagnetic momentum is a fundamental physical concept that has been demonstrated experimentally and incorporated theoretically in various areas of physics. In spite of the weak character of the electromagnetic momentum transfer process, the combination of latter-day, high-energy laser light sources and microminiature mechanical elements suggested the possibility of optical excitation of these structures. One outcome of the present theoretical analysis is the prediction of an optopiezic effect wherein electromagnetic momentum causes a mechanical stress on a dielectric layer. If this is a valid prediction, such an optically induced, expansional pressure effect could be utilized as an extensional optical-to-mechanical transduction means. copyright 1997 Optical Society of America

CSR Strategies in Greater China: Global, East Asian, American, European Style?

Directory of Open Access Journals (Sweden)

Heiduk Guenter

2014-10-01

Full Text Available The concept of Corporate Social Responsibility emerged in the United States and spread to Europe and Asia while being adapted to national/local characteristics. Since borders between markets and societies are blurring and globalization is promoting MNCs which find themselves acting in hybrid societies, international institutions put efforts into the development and moral acceptance of global CSR standards. The scientific interest in CSR focused on the conflicts between company returns and benefits for society. The resulting concepts of performance-oriented, awareness-oriented and welfare-oriented CSR should facilitate the evaluation of CSR strategies implemented by MNCs. In research on the cultural dimensions of economies, it might be possible to allocate geographically the three concepts. Regarding the newly emerging Chinese MNCs, the paper aims to shed light on which concept they follow. On the one hand, CSR concepts of American and/or European MNCs that are present in China might serve as a role model; on the other hand, by learning from Taiwanese/ Hong Kong MNCs, a “greater China CSR approach” might emerge. Empirical studies and own field research suggest that compared to American and European companies, CSR is less deeply rooted in Chinese companies. Furthermore, significant differences between Mainland China, Hong Kong and Taiwanese companies indicate that a Greater Chinese CSR approach does not yet exist. Therefore, it cannot be assumed that American and European CSR concepts will experience a Chinese influence in the near future.

Cambodia–China Relations: A Positive-Sum Game?

Directory of Open Access Journals (Sweden)

Pheakdey Heng

2012-01-01

Full Text Available China has re-emerged to become a dominant foreign player in Cambodia. Politically, Cambodia is one of China’s oldest and closest allies. Economically, China is Cambodia’s top foreign investor, a major donor, and an increasingly important trading partner. Culturally, Chinese values are deeply embedded in many aspects of Cambodian society. However, China’s dominance is surrounded by renewed controversies. While the government warmly welcomes Chinese aid, saying that it comes with no strings attached, many experts are concerned that China is providing aid for more nefarious reasons. Critics also accuse Chinese investment and aid of having exacerbated corruption, weakened governance and harmed human rights, and of ruining Cambodia’s natural resources and environment. With such controversies, it is relevant and significant to assess the roles that China has played and continues to play in Cambodia’s socio-economic development. Using expert interviews, media analysis and an extensive literature review, this paper uniquely contributes to the existing discussion on China–Cambodia relations by closely examining the controversies of China’s investment and aid, critically analysing China’s interests in Cambodia, and asking if the relationship between the two nations is a positive-sum game.

Barriers' and policies' analysis of China's building energy efficiency

Zhang, Yurong; Wang, Yuanfeng

2013-01-01

With the rapid economic growth and the improvement of people's living standards, China's building energy consumption has kept rising during the past 15 years. Under the effort of the Chinese government and the society, China's building energy efficiency has made certain achievements. However, the implementation of building energy efficiency in China is still far from its potential. Based on the analysis of the existing policies implemented in China, the article concluded that the most essential and the most effective ways to promote building energy efficiency is the government's involvement as well as economic and financial incentives. In addition, the main barriers in the process of promoting building energy efficiency in China are identified in six aspects. It has been found that the legal system and administrative issues constitute major barriers, and the lack of financial incentives and the mismatching of market mechanism also hamper the promotion of building energy efficiency. Finally, in view of the existing policies and barriers analysis, three corresponding policy proposals are presented. -- Highlights: •The existing policies implemented in China from three aspects are presented and analysed. •The Government's involvement is the most essential effective way to promote building-energy efficiency. •Six aspects of barriers in promoting building energy efficiency in China are identified. •The legal system and administrative issues constitute the major barriers. •Three policy proposals to further promote building energy efficiency in China are proposed

Influence of Aerosols And Surface Reflectance On NO2 Retrieval Over China From 2005 to 2015

Satellite observation is a powerful way to analysis annual and seasonal variations of nitrogen dioxide (NO2). However, much retrieval of vertical column densities (VCDs) of normally do not explicitly account for aerosol optical effects and surface reflectance anisotropy that vary with space and time. In traditional retrieval, aerosols' effects are often considered as cloud. However, China has complicated aerosols type and aerosol loading. Their optical properties may be very different from the cloud. Furthermore, China has undergone big changes in land use type in recent 10 years. Traditional climatology surface reflectance data may not have representation. In order to study spatial-temporal variation of and influences of these two factors on variations and trends, we use an improved retrieval method of VCDs over China, called the POMINO, based on measurements from the Ozone Monitoring Instrument (OMI), and we compare the results of without aerosol, without surface reflectance treatments and without both to the original POMINO product from 2005 to 2015. Furthermore, we will study correspondent spatial-temporal variations of aerosols, represented by MODIS aerosol optical depth (AOD) data and CALIOP extinction data; surface reflectance, represented by MODIS bidirectional reflectance distribution function (BRDF) data.

How Africans Pursue Low-End Globalization in Hong Kong and Mainland China

Gordon Mathews

2012-01-01

Full Text Available This article looks at the livelihoods and lives of African traders coming to Hong Kong and Guangzhou. These traders are practising “low-end globalization”, involving small amounts of capital, and semi-legal or illegal transactions under the radar of the law. The article first considers who these traders are, portraying them as, typically, members of the upper crust of their home societies. It then considers these traders in Chungking Mansions, Hong Kong, a building that is an entrepôt between China and the developing world. Finally, it looks at traders’ livelihoods and lives in Guangzhou, South China, and traders’ efforts to succeed in mainland China. The article argues that one essential economic role China plays today is in manufacturing the cheap, sometimes counterfeit goods that enable Africa and other developing-world regions to experience globalization; the African traders who come to China help make this possible.

Poliomyelitis has historically been endemic in China and has been considered an important cause of disability and death. We reviewed strategies and measures of poliomyelitis control and eradication from 1953 to 2012. Data from notifiable disease and routine immunization reporting systems and acute flaccid paralysis (AFP) surveillance were analyzed. About 20 000 poliomyelitis cases were reported annually in the prevaccine era. During 1965-1977, live, attenuated oral poliomyelitis vaccine (OPV) was administered to children through annual mass campaigns in the winter, and the number of poliomyelitis cases started to decline. A cold chain system was established during 1982, and OPV coverage increased during the early stage of the Expanded Programme on Immunization, from 1978 to 1988. Between 1989 and 1999, routine immunization was strengthened, supplementary immunization activities (SIAs) were conducted, and the AFP surveillance system was established. China reported a last indigenous poliomyelitis case in 1994 and was certified as free of polio in 2000. To maintain its polio-free status, China kept >90% coverage of 3 doses of OPV, conducted SIAs in high-risk areas, and maintained high-quality of AFP surveillance. China succeeded in stopping the outbreak in Xinjiang in 2011. China's polio-free status was achieved and maintained through strengthening routine immunization and implementing SIAs and AFP surveillance. © The Author 2014.

Income inequality and health in China: A panel data analysis.

Science.gov (United States)

Bakkeli, Nan Zou

2016-05-01

During the last decades, the level of income inequality in China has increased dramatically. Despite rapid economic growth and improved living conditions, the health performance in China has dropped compared to the period before the economic reform. The "Wilkinson hypothesis" suggests that increased income inequality in a society is correlated to worse health performance. China is a particular interesting case due to the rapid socioeconomic change in the country. This study uses the China Health and Nutrition Survey (CHNS) to address the question of whether income inequality has an impact on individuals' risks of having health problems in China. Unlike previous studies with health measures such as self-reported health or mortality rate, our study uses physical functions to measure individual health. By analysing panel data using county/city-level dummies and year fixed-effects, we found that income inequality does not have a significant impact on individuals' risks of having health problems. This result is robust when changing between different indicators for income inequality. Copyright © 2016 Elsevier Ltd. All rights reserved.

Smilax china root, which is rich in resveratrol and oxyresveratrol, has been used as emergency foods as well as folk medicine. This study investigated changes in concentration of bioactive components and the free-radical scavenging capacity of Smilax china root during fermentation by Aspergillus usami and Saccharomyces cerevisiae. Resveratrol, oxyresveratrol and piceid were quantified as major constituents in Smilax china root by using UPLC-ESI-MS. The concentration of oxyresveratrol and resveratrol remarkably increased through fermentation and the transformation of piceid to resveratrol. Its concentration in 4% Smilax china root was 1.16-2.95 times higher than that of a 2% preparation throughout fermentation. The vitamin C equivalent antioxidant capacity of 2% Smilax china root was 1.51-1.91 times higher than that of 4% Smilax china root during fermentation. Meanwhile, ABTS free-radical scavenging capacity was enhanced up to 95.07 and 99.35% for 2% and 4% Smilax china root, respectively. Results from our study propose that bioactive components in Smilax China root were highly extracted by fermentation followed by saccharification and ethanol production, resulting in enhanced free-radical scavenging capacity. © 2013 Society of Chemical Industry. © 2013 Society of Chemical Industry.

Species of the genus Retiboletus (Boletaceae, Boletales) in China are investigated based on morphology and phylogenetic analyses of DNA sequences from nuc rDNA internal transcribed spacer (ITS) and partial 28S regions and sequences from the translation elongation factor 1-a gene (tef1a). Six lineages are recovered among the collections studied. Five of these are documented and presented in the present paper, including three new species and two new combinations. The remaining species is not described due to the paucity of material. The specimens from China identified as "R. ornatipes" or "R. retipes" are in fact R. sinensis or R. kauffmanii, those labeled "R. griseus" are either R. fuscus or R. pseudogriseus A key to all known taxa of the genus is provided. Phylogenetic relationships of taxa within Retiboletus are partially resolved. A preliminary biogeographical analysis shows that allied species of Retiboletus between eastern Asia and North/Central America are common but there are no Retiboletus species common to both continents. Species of Retiboletus in Japan and southern China are conspecific or closely related. © 2016 by The Mycological Society of America.

Marital role attitudes and expected role behaviors of college youth in mainland China and Taiwan.

Hsieh, K H; Burgess, R L

1994-09-01

Mainland China and Taiwan have been politically and physically segregated since 1949, and it was not until the late 1980s that limited contacts and cultural exchanges between the two societies began to take place. During their period of segregation, the two societies adopted different approaches toward gender roles. While gender equality was actively promoted in mainland China, the government in Taiwan lacked the theoretical guidance on how to achieve such equality. Gender egalitarianism in Taiwan therefore remains at the abstract or philosophical level with no specification of what gender equality means in concrete terms. Testing the hypothesis that people in mainland China have become more egalitarian than have people in Taiwan with respect to the division of marital roles, the authors investigated the differences in marital role attitudes and expected behavior among selected college students in mainland China and Taiwan. Survey responses were obtained from 185 male and 154 female students from Taiwan and 150 male and 138 female students from mainland China of different years and majors on four dimensions of marital role attitudes and six areas of traditional husband and wife role behaviors. The dimensions were determined through exploratory and confirmatory factor analyses. The data indicate that although most of the hypothesized societal differences are supported, some are not. The authors speculate that possible regressive changes in mainland China and progressive changes in Taiwan during the past decade were responsible for the discrepancy between hypotheses and results.

2018-01-01

Cancer has become a major disease burden across the globe. It was estimated that 4.29 million new incident cases and 2.81 million death cases of cancer would occur in 2015 in China, with the age-standardized incidence rate (ASIR) of 201.1 per 100,000 and age-standardized mortality rate (ASMR) of 126.9 per 100,000, respectively. For females, 2 of the top 10 most common types of cancer would be gynecologic cancers, with breast cancer being the most prevalent (268.6 thousand new incident cases) and cervical cancer being the 7th most common cancer (98.9 thousand new incident cases). The incidence and mortality of gynecologic cancers have been constantly increasing in China over last 2 decades, which become a major health concern for women. Survival rates of gynecologic cancers are generally not satisfactory and decrease along with advancing stage, though national data on survival are still not available. It is of great importance to overview on the epidemiology of gynecologic cancers, which may provide scientific clues for strategy-making of prevention and control, and eventually lowering the incidence and mortality rate as well as improving the survival rate in the future.

Full Text Available Natural gas hydrate, also known as combustible ice, and mainly composed of methane, is identified as a potential clean energy for the 21st century. Due to its large reserves, gas hydrate can ease problems caused by energy resource shortage and has gained attention around the world. In this paper, we focus on the exploration and development of gas hydrate as well as discussing its status and future development trend in China and abroad. We then analyze its opportunities and challenges in China from four aspects, resource, technology, economy and policy, with five forces model and Politics Economics Society Technology method. The results show China has abundance gas hydrate resource; however, backward technologies and inadequate investment have seriously hindered the future development of gas hydrate; thus, China should establish relevant cooperation framework and intuitional arrangement to attract more investment as well as breaking through technical difficulties to commercialization gas hydrate as soon as possible.

How kinship systems and welfare regimes shape leaving home: A comparative study of the United States, Germany, Taiwan, and China

Directory of Open Access Journals (Sweden)

Bernhard Nauck

2017-04-01

Full Text Available Objective: This paper aims to explain societal differences in the event of leaving the parental home as part of the transition to adulthood, in the United States, Germany, China, and Taiwan. It proposes bridge hypotheses between societal characteristics such as kinship system and welfare regime and home-leaving behavior, and tests them with nationally representative panel studies. Methods: Four panel studies (NLSY97 for the USA; PAIRFAM for Germany; CFPS for China; TYP for Taiwan were harmonized for similar cohorts, with an age span of 15 to 30 years. Testing was based on age-specific tabulations of household composition and separate discrete-time event history models. Results: The prevalence of home-leaving is highest in the United States, followed by Germany, China, and then Taiwan. Timing is earlier in the United States than in Germany, and earlier in China than in Taiwan. Gender-specific coincidence of home-leaving with entry into higher education, the work force, cohabitation, and marriage can be conclusively related to differences in kinship system and welfare regime, and regional opportunity disparities. Contribution: The empirical results point to significant cultural differences between home-leaving in collectivistic, patrilineal societies (China, Taiwan and individualistic, bilineal societies (USA, Germany. Whereas neolocal housing signifies an important step in the transition to adulthood in the latter societies, continuous intergenerational housing, or even an early return to it, is normatively supported in collectivistic cultures. Differences between the United States and Germany on the one hand, and China and Taiwan on the other, point to variation in welfare regimes and differences in urbanization.

To achieve an in-depth understanding of the aerosol optical properties in the highly-industrial region of Tangshan, we provided systematic aerosol optical properties analysis in this largest industrial zone for the first time. The aerosol optical datasets (2013.05-2015.04) and chemical component data of PM2.5 (2014-2015) obtained from the Tangshan site of the campaign on atmospheric aerosol research (CARE-China) network were analyzed. The results showed that the Tangshan region was seriously affected by fine-mode industrial aerosols all year, which would promote the accumulation of pollutants and influence the atmospheric circulation through changing the vertical temperature gradient. The annual average aerosol optical depth (AOD) and Ångstrӧm exponent (α) were 0.80 ± 0.26 and 1.05 ± 0.10, respectively. The aerosol optical properties revealed significant seasonal characteristics. The maximum seasonal average AOD (1.03 ± 0.62) and α (1.12 ± 0.19) accompanied the highest seasonal secondary inorganic aerosol concentrations (SIA: SO42 -, NO3-, NH4+), 53.33 μg/m3, occurred in summer, and this phenomenon was attributed to the photochemical reactions favored by the high temperature and humidity. During the spring, frequent dust events led to the maximum Ca2 + concentration of 6.57 μg/m3 and the lowest seasonal α of 0.98 ± 0.31. Coal was used for generating heat in winter, resulting in the highest levels of pollutant emissions (Cl-, Elemental carbon (EC) and organic carbon (OC)). The aerosol type classifications showed that the industrial aerosols were the main controls in the summer and fall, representing 56%-58% of the total aerosols. While for spring and winter, mixed aerosols represented 53%-54% of the total aerosols. Hygroscopic growth effect of aerosols existed all year, which could enhance the negative radiative forcing and eventually cool the earth-atmosphere system. The classification Wing for Tangshan data showed high AOD values (> 0.70) were mainly

Analysis and evaluation for social acceptability for utilizing nuclear power in China

International Nuclear Information System (INIS)

Xu, Ting; Wakabayashi, Toshio

2011-01-01

This study is about the acceptability of the society of utilizing nuclear power in China. There are different interactions and opinions has been raised that leads conflict between the society and the nuclear technology people. Many emotions and views have mixed up: people have image of environment friendly, also have image of explosion, fright and danger. The purpose of this study is to make clear the social consciousness for utilizing nuclear power in China and to improve social acceptability. A survey by the questionnaire was conducted for investigation of the features of the social consciousness for necessity and safety for utilizing nuclear power in China. The questionnaire has been sent to 10000 citizens of Zhejiang province in south China from June to August 2010 (Zhejiang province is one of the earliest city for utilizing nuclear power plants in China). There were 4255 available respondents (42.6%) with 1851 men and 2404 women of adult who answered the questionnaire. The survey was including 37 items about energy problem, social consciousness for utilizing nuclear power, safety, the reliability of government and information sources. As a result, it was found that some 57.5% of adults are in favor of nuclear power plants. There are differences of sense between men and women. The reliability for safety of men for nuclear power is higher than that of women. Some 59.6% of men respondents are in favor of nuclear power plants, and about 10% respondents of women are in favor of nuclear power plants. Social acceptance is still one of the major barriers for further development of nuclear power, although recent technological and institutional innovation is clearly reduced its risk and enhanced its relative and absolute benefit compared to other energy resources. Consequently, this result indicates that women with maternal instinct may not be favor of nuclear power plants compared with men in China. (author)

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

An Analysis of China's Fertilizer Policies: Impacts on the Industry, Food Security, and the Environment.

China has made remarkable strides in recent decades to grow enough food to feed 20% of the world's population with only 9% of the world's arable land. Meanwhile, the nation is experiencing exacerbated air and water pollution problems. Agricultural growth and the pollution aggravation are closely linked with policies affecting fertilizer production and use. Essentially nonexistent in 1950, China's fertilizer industry is now a robust conglomerate producing fertilizers in amounts that not only meet domestic demand but also contribute to international trade. The industry's growth stemmed from a series of policy progressions, featuring (i) a total control system with state ownership and central planning (1949-1984), (ii) a dual system of central planning and market adjustment (1985-1997), (iii) a market-driven system with government-mandated price caps (1998-2009), and (iv) a complete market-oriented system (since 2009). In conjunction with the policy changes were massive subsidy programs totaling more than $18 billion in 2010. The support policies and subsidies helped grow the industry and safeguard an adequate supply of fertilizers at affordable costs to farmers, but the artificially low-priced fertilizers also contributed to a nationwide trend of fertilizer overuse, leading to nutrient pollution. China needs innovative policies and programs to address food security and sustainability challenges. In this study, we review and analyze policies and programs related to China's fertilizer production and use in a 60-yr span (1950-2010) and discuss its impact on the development of the industry, food security, and pressing environmental issues. Finally, our study analyzes long-term trends in fertilizer use in China and offers some key viewpoints to stimulate debates among all stakeholders.

2009-01-01

Organ procurement in China has been criticized because of its reliance on executed prisoners as donors. We aimed to assess the influence of perceptions about organ procurement practices in China on domestic patient-care decisions. An anonymous internet administered case-based questionnaire was used to survey a sample of healthcare professionals with affiliations to hepatology and transplantation professional societies. Of 674 completed surveys, the vast majority (93%) of the respondents were physicians, surgeons or allied transplant professionals actively caring for liver transplant patients and 81% practiced in the US. A strong majority believed procurement practices were ethically sound in the US and Europe (87% and 73%) but fare fewer believed that procurement practices were ethically sound in China (4%, p < 0.001). In case-based questions, lack of confidence in the ethical standards of organ procurement in China predicted patient-care decisions. The majority would provide post-transplantation care for patients who underwent liver transplantation at another domestic center, in a foreign country and in China (90%, 78%, and 63%, respectively, p < 0.001) yet respondents who suspected unethical procurement practices in China were more reluctant to do so (p < 0.001). Transplant professionals expressed concern about organ procurement practices in China which influenced their patient-care decision-making.

Full Text Available Past research has documented various cultural and psychological changes in contemporary China. In two studies, we examine how Chinese people’s need for uniqueness (NFU also has changed. In Study 1, we found a significant cross-generational increase in Chinese participants’ self-reported NFU. In Study 2, we sampled the names of Chinese newborn babies over the last five decades and found that parents have been increasingly likely to use unique characters to name their children. These findings suggest that the NFU has been rising in China, a historically collectivistic-oriented society. Theoretical and practical implications of our findings were discussed.

The psychological capacity to recognize that others may hold and act on false beliefs has been proposed to reflect an evolved, species-typical adaptation for social reasoning in humans; however, controversy surrounds the developmental timing and universality of this trait. Cross-cultural studies using elicited-response tasks indicate that the age at which children begin to understand false beliefs ranges from 4 to 7 years across societies, whereas studies using spontaneous-response tasks with Western children indicate that false-belief understanding emerges much earlier, consistent with the hypothesis that false-belief understanding is a psychological adaptation that is universally present in early childhood. To evaluate this hypothesis, we used three spontaneous-response tasks that have revealed early false-belief understanding in the West to test young children in three traditional, non-Western societies: Salar (China), Shuar/Colono (Ecuador) and Yasawan (Fiji). Results were comparable with those from the West, supporting the hypothesis that false-belief understanding reflects an adaptation that is universally present early in development.

Jinah Park

2018-04-01

Full Text Available Tourism is a critical, cross-cultural social behavior in contemporary society and provides diverse experiences based on different regional resources in destinations. This research identified the attributes associated with Korean golf tourists’ images of seven destination regions in Mainland China. A content analysis of 328 golf tourists’ blogs indicated that each region had different combinations of destination attributes, but these were partially hidden in vivid descriptions of playing experiences. The narratives were coded with 15 golf destination attributes with 136 headwords and they reflected both place-centred images and interactions through perceptual experiences with different social groups. The golfers greatly appreciated congestion control at courses and social interaction during their tours, including the services of local human resources and play partners. The seven Chinese golf destinations had different perceived characteristics and relationships with South Korean society. Thus, they had dissimilar destination images for Korean golf tourists. Historical ties and geographical proximity played important roles, including, for example, the significant presence of ethnic Koreans in northeast China.

In recent years, the Ministry of Education of China attaches great importance to the reform of higher education quality. As an important link in the reform of higher education, curriculum development is bound to promote the development of "quality-centered connotative education". Zhejiang University, Changchun University of Science and Technology, Southern Airlines University and other colleges and universities carried out a full range of close cooperation, proposed integrated innovation teaching mode of the course based on network technology. Based on this model, the course of "Applied Optics" has been practiced for two years. The results show that the integrated innovation teaching mode can fully realize the integration amplification effect among multiple colleges and universities and the depth sharing all types of resources. Based on the principle of co-building and sharing, mutual help, comprehensively improve the teaching quality of domestic related courses and promote the comprehensive development of the curriculum to meet the needs of learning society.

Since China first applied isotopes to medical research in 1956, over 800 hospitals and research institutions with 4000 staff have taken up nuclear technology. So far, over 120 important biologically active materials have been measured by radioimmunoassay in China, and 44 types of RIA kit have been supplied commercially. More than 50,000 cases of hyperthyroidism have been treated satisfactorily with 131 I. Radionuclide imaging of practically all organs and systems of the human body has been performed, and adrenal imaging and nuclear cardiology have become routine clinical practice in several large hospitals. The thyroid iodine uptake test, renogram tracing and cardiac function studies with a cardiac probe are also commonly used in most Chinese hospitals. The active principles of more than 60 medicinal herbs have been labelled with isotopes in order to study the drug metabolism and mechanism of action. Through the use of labelled neurotransmitters or deoxyglucose, RIA, radioreceptor assay and autoradiography, Chinese researchers have made remarkable achievements in the study of the scientific basis of acupuncture analgesia. In 1980 the Chinese Society of Nuclear Medicine was founded, and since 1981 the Chinese Journal of Nuclear Medicine has been published. Although nuclear medicine in China has already made some progress, when compared with advanced countries, much progress is still to be made. It is hoped that international scientific exchange will be strengthened in the future. (author)

The aim of this study was to investigate the susceptibility of flomoxef against clinical isolates collected from China and understand the trend of antimicrobial resistance. A total of 2955 pathogenic strains isolated from 18 tertiary hospitals in 18 cities of China over the period from July 2011 to June 2012 were studied. And the susceptibility tests were performed using agar dilution method recommended by CLSI in central laboratory. Flomoxef showed good potency against Enterobacteriaceae with susceptibility rate 85%-100%. The susceptibility rates of flomoxef against Staphylococcus spp. isolates were 63.9%-92.2%; 98.8% of MSSA and 88.2% of MSSE were susceptible to this drug. For other tested bacteria including Moraxella catarrhalis, Haemophilus spp., and Streptococcus spp. (except Viridans group streptococci) flomoxef showed good potency with susceptibility rate more than 95%. All these results strongly suggest that flomoxef is a potent antibacterial agent against major pathogens in China.

Hughes, Terry P; Huang, Hui; Young, Matthew A L

2013-04-01

We examined the development of coral reef science and the policies, institutions, and governance frameworks for management of coral reefs in China in order to highlight the wicked problem of preserving reefs while simultaneously promoting human development and nation building. China and other sovereign states in the region are experiencing unprecedented economic expansion, rapid population growth, mass migration, widespread coastal development, and loss of habitat. We analyzed a large, fragmented literature on the condition of coral reefs in China and the disputed territories of the South China Sea. We found that coral abundance has declined by at least 80% over the past 30 years on coastal fringing reefs along the Chinese mainland and adjoining Hainan Island. On offshore atolls and archipelagos claimed by 6 countries in the South China Sea, coral cover has declined from an average of >60% to around 20% within the past 10-15 years. Climate change has affected these reefs far less than coastal development, pollution, overfishing, and destructive fishing practices. Ironically, these widespread declines in the condition of reefs are unfolding as China's research and reef-management capacity are rapidly expanding. Before the loss of corals becomes irreversible, governance of China's coastal reefs could be improved by increasing public awareness of declining ecosystem services, by providing financial support for training of reef scientists and managers, by improving monitoring of coral reef dynamics and condition to better inform policy development, and by enforcing existing regulations that could protect coral reefs. In the South China Sea, changes in policy and legal frameworks, refinement of governance structures, and cooperation among neighboring countries are urgently needed to develop cooperative management of contested offshore reefs. © 2012 Society for Conservation Biology.

The aerosol radiative effect can be modulated by the vertical distribution and optical properties of aerosols, particularly when aerosol layers are decoupled. Direct aerosol radiative effects over the northern South China Sea (SCS) were assessed by incorporating an observed data set of aerosol optical properties obtained from the Seven South East Asian Studies (7-SEAS)/Dongsha Experiment into a radiative transfer model. Aerosol optical properties for a two-layer structure of aerosol transport were estimated. In the radiative transfer calculations, aerosol variability (i.e., diversity of source region, aerosol type, and vertical distribution) for the complex aerosol environment was also carefully quantified. The column-integrated aerosol optical depth (AOD) at 500 nm was 0.1-0.3 for near-surface aerosols and increased 1-5 times in presence of upper layer biomass-burning aerosols. A case study showed the strong aerosol absorption (single-scattering albedo (ω) ≈ 0.92 at 440 nm wavelength) exhibited by the upper layer when associated with predominantly biomass-burning aerosols, and the ω (≈0.95) of near-surface aerosols was greater than that of the upper layer aerosols because of the presence of mixed type aerosols. The presence of upper level aerosol transport could enhance the radiative efficiency at the surface (i.e., cooling) and lower atmosphere (i.e., heating) by up to -13.7 and +9.6 W m-2 per AOD, respectively. Such enhancement could potentially modify atmospheric stability, can influence atmospheric circulation, as well as the hydrological cycle over the tropical and low-latitude marginal northern SCS.

Chinese Anti-Cancer Association as a non-governmental organization undertakes systematic cancer prevention work in China

Science.gov (United States)

2015-01-01

Cancer has become the first leading cause of death in the world, particularly in low- and middle-income countries. Facing the increasing trend of cancer incidence and mortality, China issued and implemented “three-early (early prevention, early diagnosis and early treatment)” national cancer prevention plan. As the main body and dependence of social governance, non-governmental organizations (NGOs) take over the role of government in the field of cancer prevention and treatment. American Cancer Society (ACS) made a research on cancer NGOs and civil society in cancer control and found that cancer NGOs in developing countries mobilize civil society to work together and advocate governments in their countries to develop policies to address the growing cancer burden. Union for International Cancer Control (UICC), Cancer Council Australia (CCA), and Malaysian cancer NGOs are the representatives of cancer NGOs in promoting cancer control. Selecting Chinese Anti-Cancer Association (CACA) as an example in China, this article is to investigate how NGOs undertake systematic cancer prevention work in China. By conducting real case study, we found that, as a NGO, CACA plays a significant role in intensifying the leading role of government in cancer control, optimizing cancer outcomes, decreasing cancer incidence and mortality rates and improving public health.

Greg Linden

2003-01-01

China’s industrial policy for high-technology industries combines key features of the policies adopted elsewhere in East Asia: judicious opening to foreign investors and support for local firms. However, unlike the developing economies of East Asia, China is a transition economy that already had a relatively well-developed, if somewhat dated, technology base of its own before its opening to outside investors at the end of the 1970s. Although the initial technology level of indiv...

We have investigated the chemical and optical properties of aerosol particles during the 2014 Asia-Pacific Economic Cooperation (APEC) summit in Beijing, China, using the highly time-resolved measurements by a high-resolution aerosol mass spectrometer and a cavity attenuated phase shift extinction monitor. The average (±σ) extinction coefficient (bext) and absorption coefficient (bap) were 186.5 (±184.5) M m-1 and 23.3 (±21.9) M m-1 during APEC, which were decreased by 63% and 56%, respectively, compared to those before APEC primarily due to strict emission controls. The aerosol composition and size distributions showed substantial changes during APEC; as a response, the mass scattering efficiency (MSE) of PM1 was decreased from 4.7 m2 g-1 to 3.5 m2 g-1. Comparatively, the average single-scattering albedo (SSA) remained relatively unchanged, illustrating the synchronous reductions of bext and bap during APEC. MSE and SSA were found to increase as function of the oxidation degree of organic aerosol (OA), indicating a change of aerosol optical properties during the aging processes. The empirical relationships between chemical composition and particle extinction were established using a multiple linear regression model. Our results showed the largest contribution of ammonium nitrate to particle extinction, accounting for 35.1% and 29.3% before and during APEC, respectively. This result highlights the important role of ammonium nitrate in the formation of severe haze pollution during this study period. We also observed very different optical properties of primary and secondary aerosol. Owing to emission controls in Beijing and surrounding regions and also partly the influences of meteorological changes, the average bext of secondary aerosol during APEC was decreased by 71% from 372.3 M m-1 to 108.5 M m-1, whereas that of primary aerosol mainly from cooking, traffic, and biomass burning emissions showed a smaller reduction from 136.7 M m-1 to 71.3 M m-1.

Milk composition and its fatty acid profile have received much attention with respect to improving human health. However, limited work has been conducted to assess the composition of milk fat in China, which is the third largest producer of milk in the world. In this study the effects of geographical region and seasonal changes (spring and summer) on the fatty acid composition of milk samples collected from six Chinese farms were investigated. Milk fat and protein contents, as well as some individual fatty acids and five fatty acid groups, were found to be unaffected by season, but they did show significant differences by geographical region. Levels of milk cis-9, trans-11 conjugated linoleic acid decreased in summer and increased in spring, increased in north (Hohhot), northeast (Harbin), north centre (Beijing) and northwest (Xi'an) China and decreased in far northwest (Urumqi) and east (Chuzhou) China. Monounsaturated fatty acids increased in east and northwest China and decreased in northeast China, while polyunsaturated fatty acids increased in far northwest and north centre China and decreased in northeast China. This study provides relevent information that contributes to the understanding of parameters affecting variability of milk fatty acid profiles. © 2012 Society of Chemical Industry.

China has been experiencing huge changes in all aspects, including dermatologic research, since its reform in 1978. However, it is not known how the economic and intellectual development has influenced the publication trends in the field of dermatology, which could mirror the scientific development in other medical disciplines. In the present study, we analyzed publication trends from dermatology departments in mainland China from 2002 to 2011. All publication data were obtained from www.pubmed.com. Only papers published from dermatology departments in mainland China were used for analysis. The number of publications increased 10-fold over this 10-year period. A total of 1231 articles were published in English in 251 journals between 2002 and 2011. A total of 129 journals published only one paper from dermatology departments in mainland China. Over 60% of articles were original research, and 21.7% were case reports. Among these 251 journals, foremost was the Journal of Clinical Experimental Dermatology, which published 5.9% of all papers from mainland China; 2.7% of papers were published in the Journal of Investigative Dermatology. The number of publications positively correlated with the changes in gross domestic product per capita during the study period. These results suggest that the number of publications in the dermatology field has increased markedly in mainland China over the last 10 years. This dramatic increase in publications could be attributed, at least partially, to the significant improvement in economic conditions in mainland China. © 2013 The International Society of Dermatology.

Structures and Logic of EP Implementation and Administration in China

Dieter Grunow

2011-01-01

Full Text Available This paper describes empirical observations gathered during a research project on the implementation of environmental protection (EP policies in China. The project focused on local EP in both urban and rural areas. Policy field analysis was used as a conceptual framework for structuring the observations. The paper develops in three main steps discussing the following topics: 1 Collective problems within the policy field of EP show that EP issues in general are unlike those of other policy fields. Official EP policies in China today resemble those of other countries – but they are separating issues and responsibilities, making local implementation very demanding. 2 China lags behind in its willingness and ability to implement these policies – leading to implementation gaps. To explore the causes and consequences, specific sites in China are described in an extended look at local implementation structures. It was found that although policies in China are basically the same everywhere, the structures for implementing them and the quality of their implementation vary widely with regard to resources, organization, coordination, staff qualifications, personnel placement, and other aspects. 3 Not all of the challenges hampering local implementation of environmental policies were China-specific; however, some of those which are can be described as the macro-context: an ineffective rule of law, insufficient involvement of civil society, and complicated macro-structures of public administration prevent a generally high level of successful EP implementation in China.

Does who you know in the positional hierarchy protect or hurt? Social capital, comparative reference group, and depression in two societies.

Does the socioeconomic status (SES) that one's (ego's) network members (alters) occupy indicate social resources or social comparison standards in the dynamics of health across culture? Using nationally representative data simultaneously collected from the United States and urban China, this study examines two competing theories-social capital and comparative reference group-in the two societies and compares their different application across the two societies using two cultural explanations, relational dependence and self-evaluation motive. Social capital theory expects absolute accessed SES and the size of higher accessed socioeconomic positions to protect health, and the size of lower accessed socioeconomic positions to harm health. But comparative reference group theory predicts the opposite. Additionally, the relational dependence explanation anticipates social capital theory to be more applicable to urban China and comparative reference group theory to be more applicable to the United States. The self-evaluation motive explanation expects the same pattern across the two societies in the examination of the size of lower accessed socioeconomic positions but the opposite pattern in the analysis of absolute accessed SES and the size of higher accessed socioeconomic positions. This study focuses on depressive symptoms and measures accessed occupational status. Results are consistent with the self-evaluation motive explanation. They support both social capital theory and comparative reference group theory in the United States but only the latter theory in urban China. Copyright © 2015 Elsevier Ltd. All rights reserved.

The aim of this study was to analyze the barriers in the implementation of the Framework Convention on Tobacco Control (FCTC) in China and present recommendations on ways to address these challenges in tobacco control in China. We review the available literature on progress and explore the barriers and challenges that impede a speedier pace in the adoption of the effective tobacco control measures, and present recommendations based on in-depth knowledge of decision-making process on the implementation of FCTC in China. The pace of progress in China is too slow. China faces intractable political, structural, economic and social barriers in tobacco control, which make the whole-hearted implementation of FCTC measures a painstaking process. The authors recommend a comprehensive approach to speed up the implementation of tobacco control measures. This includes strong political leadership from the top, structural changes to the tobacco industry and government oversight of the tobacco industry, as well as advocacy and support for tobacco control from civil society at the grassroots level.

Li, X. S.; Peng, Z. Y.; Li, T. T.

2016-08-01

This paper establishes an evaluation index system of water security. The index system employs 5 subsystems (water circulation security, water environment security, water ecology security, water society security and water economy security) and has 39 indicators. Using the AHP method, each indicator is given a relative weight to integrate within the whole system. With macroeconomic data from 2000 to 2012, a model of water security evaluation is applied to assess the state of water security in China. The results show an improving trend in the overall state of China's water security. In particular, the cycle of water security is at a high and low fluctuation. Water environment security presents an upward trend on the whole; however, this trend is unsteady and has shown a descending tendency in some years. Yet, water ecology security, water society security, and water economy security are basically on the rise. However, the degree of coordination of China's water security system remains in need of consolidation.

For traditional coherent effects, two separated identical point sources can be interfered with each other only when the optical path difference is integer number of wavelengths, leading to alternate dark and bright fringes for different optical path difference. For hundreds of years, such a perfect coherent condition seems insurmountable. However, in this paper, based on transformation optics, two separated in-phase identical point sources can induce perfect interference with each other without satisfying the traditional coherent condition. This shifting illusion media is realized by inductor-capacitor transmission line network. Theoretical analysis, numerical simulations and experimental results are performed to confirm such a kind of perfect coherent effect and it is found that the total radiation power of multiple elements system can be greatly enhanced. Our investigation may be applicable to National Ignition Facility (NIF), Inertial Confined Fusion (ICF) of China, LED lighting technology, terahertz communication, and so on.

The first optical burst switching (OBS) system has been demonstrated in China, which includes three edge routers and one core-node. A kind of fast wavelength selective optical switching was used in the system. The core OBS node consists of a kind of wavelength selective optical switch we developed. It consists of two SOA switches and one wavelength selective thin film filter with centre wavelength at one wavelength. There are one input optical fiber and two output fibers, each fiber carries two wavelengths. The Dell PE2650 servers act as the edge OBS routers. The wavelength of each data channel is located in C-band and the bit rate is at 1.25Gbps. The control channel uses bit rate of 100Mbps at wavelength of 1310 nm. A novel effective scheme for Just-In-Time (JIT) protocol was proposed and implemented. OBS services, such as Video on Demand (VOD) and file transfer protocol (FTP), have been demonstrated. Assembling and scheduling methods that are capable to guarantee the QoS (quality of service) of the transported service are studied.

Fossil-fuel combustion related winter heating has become a major air quality and public health concern in northern China recently. We analyzed the impact of winter heating on aerosol loadings over China using the MODIS-Aqua Collection 6 aerosol product from 2004-2012. Absolute humidity (AH) and planetary boundary layer height (PBL) -adjusted aerosol optical depth (AOD*) was constructed to reflect ground-level PM2.5 concentrations. GIS analysis, standard statistical tests, and statistical modeling indicate that winter heating is an important factor causing increased PM2.5 levels in more than three-quarters of central and eastern China. The heating season AOD* was more than five times higher as the non-heating season AOD*, and the increase in AOD* in the heating areas was greater than in the non-heating areas. Finally, central heating tend to contribute less to air pollution relative to other means of household heating.

Morioka, Toshio; Awaji, Yoshinari; Ryf, Roland

2012-01-01

Optical fibers have often been considered to offer effectively infinite capacity to support the rapid traffic growth essential to our information society. However, as demand has grown and technology has developed, we have begun to realize that there is a fundamental limit to fiber capacity of ~ 100...... Tb/s per fiber for systems based on conventional single-core single-mode optical fiber as the transmission medium. This limit arises from the interplay of a number of factors including the Shannon limit, optical fiber nonlinearities, the fiber fuse effect, as well as optical amplifier bandwidth...... new fibers for space-division multiplexing and mode-division multiplexing....

Some cities in China are facing serious air pollution problems including high concentrations of particles, SO2 and NOx. Exposure to PM2.5, one of the primary air pollutants in many cities in China, is highly correlated with various adverse health impacts and ultimately represents a cost for society....... The aim of this study is to assess health impacts and external costs related to PM2.5 pollution in Beijing, China with different baseline concentrations and valuation methods. The idea is to provide a reasonable estimate of the total health impacts and external cost due to PM2.5 pollution, as well...... as a quantification of the relevant uncertainty. PM2.5 concentrations were retrieved for the entire 2012 period in 16 districts of Beijing. The various PM2.5 related health impacts were identified and classified to avoid double counting. Exposure-response coefficients were then obtained from literature. Both...

2007-07-01

Full Text Available Abstract Background Although economic reforms have brought significant benefits, including improved health care to many Chinese people, accessibility to improved care has not been distributed evenly throughout Chinese society. Also, the effects of the uneven distribution of improved healthcare are not clearly understood. Evidence suggests that mortality is an indicator for evaluating accessibility to improved health care services. We constructed spatially smoothed risk maps for gender-specific adult mortality in an area of southern China comprising both urban and rural areas and identified ecological factors of gender-specific mortality across societies. Results The study analyzed the data of the Hechi Prefecture in southern in China. An average of 124,204 people lived in the area during the study period (2002–2004. Individual level data for 2002–2004 were grouped using identical rectangular cells (regular lattice of 0.25 km2. Poisson regression was fitted to the group level data to identify gender-specific ecological factors of adult (ages 15– Conclusion We found a disparity in mortality rates between rural and urban areas in the study area in southern China, especially for adult men. There were also differences in mortality rates between poorer and wealthy populations in both rural and urban areas, which may in part reflect differences in health care quality. Spatial influences upon adult male versus adult female mortality difference underscore the need for more research on gender-related influences on adult mortality in China.

This paper quantitatively evaluated the economic forest ecosystem services in the provinces of China in 2003, based on the long-term and continuous observations of economic forest ecosystems in this country, the sixth China national forest resources inventory data, and the price parameter data from the authorities in the world, and by applying the law of market value, the method of substitution of the expenses, and the law of the shadow project. The results showed that in 2003, the total value of economic forest ecosystem services in China was 11763.39 x 10(8) yuan, and the total value of the products from economic forests occupied 19.3% of the total ecosystem services value, which indicated that the economic forests not only provided society direct products, but also exhibited enormous eco-economic value. The service value of the functions of economic forests was in the order of water storage > C fixation and O2 release > biodiversity conservation > erosion control > air quality purification > nutrient cycle. The spatial pattern of economic forest ecosystem services in the provinces of China had the same trend with the spatial distribution of water and heat resources and biodiversity. To understand the differences of economic forest ecosystem services in the provinces of China was of significance in alternating the irrational arrangement of our present forestry production, diminishing the abuses of forest management, and establishing high grade, high efficient, and modernized economic forests.

HIV, Sex Work, and Law Enforcement in China.

Shen, Tingting; Csete, Joanne

HIV prevalence in China is low in the general population but higher among certain key affected populations, including sex workers. Providing and purchasing sexual services are administrative offenses. Police engage in humiliating and repressive practices against sex workers. A study reported here based on the experience of over 500 sex workers highlights that the human rights abuses that sex workers face at the hands of the police directly undermine the country's HIV response toward sex workers. An important element of this phenomenon is the police's use of condoms as evidence of sex work, which impedes sex workers' possession and use of condoms. Whereas in some countries, sex worker collectives have helped empower sex workers to stand up to the police and safeguard their use of condoms, restrictions on civil society in China make such a strategy impossible. Removing sex work and related activities as offenses under the law in China, however politically difficult it might be, would ease this situation. Short of that, improving the coordination among and strategic harmony of public health and police roles and authorities would be useful.

Identification of agricultural pest insects is an important aspect in insect research and agricultural monitoring. We have performed a methodological study of how spectroscopic techniques and wing-beat frequency analysis might provide relevant information. An optical system based on the combination of close-range remote sensing and reflectance spectroscopy was developed to study the optical characteristics of different flying insects, collected in Southern China. The results demonstrate that the combination of wing-beat frequency assessment and reflectance spectral analysis has the potential to successfully differentiate between insect species. Further, studies of spectroscopic characteristics of fixed specimen of insects, also from Central China, showed the possibility of refined agricultural pest identification. Here, in addition to reflectance recordings also laser-induced fluorescence spectra were investigated for all the species of insects under study and found to provide complementary information to optically distinguish insects. In order to prove the practicality of the techniques explored, clearly fieldwork aiming at elucidating the variability of parameters, even within species, must be performed.

How to Be Modern? The Social Negotiation of 'Good Food' in Contemporary China.

Science.gov (United States)

Zhang, Joy Y

2018-02-01

Developing safe and sustainable food production for its population has been central to China's 'Modernisation Project'. Yet recent fieldwork in three Chinese cities suggests that there are two conflicting views on what a 'modern' agriculture should look like. For the government, modernisation implies a rational calculation of scale and a mirroring of global trends. But an alternative interpretation of modernity, promoted by civil society, has been gaining ground. For this camp, good food production is then established through a 'rhizomic' spread of new practices, which are inspired by world possibilities but are deeply rooted in the local context. Based on 14 interviews and five focus groups, this article investigates the ongoing social negotiation of 'good food' in China. It demonstrates how a non-western society responds to the twin processes of modernisation and globalisation and provides insights on the varieties of modernity in the making.

China currently put forwards 'striving to build an environmentally friendly society' as one of the most important development goals. The land administration authorities are facing the challenge of effectively incorporating environment considerations into their planning system. This paper aims to investigate why and how Strategic Environmental Assessment (SEA) is enacted as an effective tool to integrate the environment into land-use planning during the construction process of an environmentally friendly society in China, and identify factors that influence the integration. It presents characteristics of the land-use planning system, and reviews the progress and current state of SEA in China. Results show that SEA provides many benefits in promoting environmental considerations into the land-use planning process. The legal frameworks and operational procedures, in the context of land-use master planning SEA, are summarized and an assessment made of their effectiveness. Some barriers are highlighted through examination of the latest case studies, and several recommendations are presented to overcome these obstacles

Chen, Q.; Tani, M.; Jiang, Zhiping; Zhang, X.-C.

2001-01-01

Because of the reciprocal behavior of the optical rectification and the electro-optic effect in a nonlinear optical crystal, an electro-optic transceiver can alternately transmit pulsed electromagnetic radiation (optical rectification) and detect the return signal (electro-optic effect) in the same crystal. However, the optimal condition of the electro-optic transceiver may be very different from that of the spatially separated emitter and receiver. We present a detailed description of the crystal-orientation dependence of the electro-optic terahertz devices (transmitter, receiver, and transceiver). It is found that for a (110) zinc-blende electro-optical crystal, the efficiency of the electro-optic transceiver will be optimized when the angle between the polarization of the optical pump beam and the crystallographic z axis [0,0,1] is 26 degree. Meanwhile, for a (111) crystal, the angle between the optical beam and the crystallographic direction [-1,-1,2] should be 23 degree. The experimental results from a (110) ZnTe transceiver verify theoretical calculations and demonstrate a direct way to optimize the working efficiency of an electro-optic terahertz transceiver.

Food adulteration has a long history in human society, and it still occurs in modern times. Because children are relatively vulnerable to food adulterants, studying the health impacts of food adulteration on children is important. This article provides an overview of the child health impacts of food adulterants in two recent food adulteration incidents in the Greater China Region: (1) a plasticizer incident in Taiwan and (2) a 2,4,6-triamino-1,3,5-triazine (melamine)-tainted milk incident in China. The involved food adulterants, di-(2-ethylhexyl) phthalate (DEHP), diisononyl phthalate (DiNP) and melamine, are harmful to the hippocampus, kidneys, reproductive organs and immune system of children, and they also increase the risk of cancer. To detect food adulteration and to avoid further harm caused by food adulteration, simple screening methods have been developed, and they have recently emerged as a new focus area for research. This article also summarizes the simple screening methods used to analyse the aforementioned food adulterants and reports how governments reacted to the recent food incidents. © 2017 Society of Chemical Industry. © 2017 Society of Chemical Industry.

Securitizing HIV/AIDS: a game changer in state-societal relations in China?

Science.gov (United States)

Lo, Catherine Yuk-Ping

2018-05-16

China has experienced unprecedented economic growth since the 1980s. Despite this impressive economic development, this growth exists side by side with the human immunodeficiency virus/acquired immune deficiency syndrome (HIV/AIDS) and severe acute respiratory syndrome (SARS) crises and the persisting deficiencies in public health provision in China. Acknowledging the prevailing health problems, the Chinese government has encouraged the development of health non-governmental organizations (NGOs) to respond to the health challenges and address the gaps in public health provision of the government. HIV/AIDS-focused NGOs have been perceived as the most outstanding civil society group developed in China. Considering the low priority of health policies since the economic reform, the limitation of the "third sector" activity permitted in authoritarian China, together with the political sensitivity of the HIV/AIDS problem in the country, this article aims to explain the proliferation of HIV/AIDS-focused NGOs in China with the usage of the securitization framework in the field of international relations (IR). The research that underpins this article is based on a desk-based literature review as well as in-depth field interviews with individuals working in HIV/AIDS-focused NGOs in China. Face-to-face interviews for this research were conducted between January and May in 2011, and between December 2016 and January 2017, in China. Discourse analysis was in particular employed in the study of the security-threat framing process (securitization) of HIV/AIDS in China. This article argues that the proliferation of HIV/AIDS-related NGOs in China is largely attributed to the normative and technical effects of HIV/AIDS securitization ushered in by the United Nations Security Council (UNSC) and supported by the Global Fund to Fight AIDS, Tuberculosis, and Malaria (hereinafter Global Fund) observed in China. Despite depicting a positive scenario, the development of HIV

Atmospheric particulate matter (PM) pollution has become a major health threat accompanying the rapid economic development in China. For decades, filter-based offline chemical analyses have been the most widely adopted means to investigate PM and have provided much information for understanding this type of pollution in China. However, offline analyses have low time resolutions and the chemical information thus obtained fail to reflect the dynamic nature of the sources and the rapid processes leading to the severe PM pollution in China. In recent years, advances in real-time PM chemical characterization have created a new paradigm for PM studies in China. In this review, we summarize those advances, focusing on the most widely used mass spectrometric and ion chromatographic techniques. We describe the findings from those studies in terms of spatiotemporal variabilities, degree of neutralization and oxygenation, source apportionment, secondary formation, as well as collocated measurements of the chemical and physical (hygroscopic and optical) properties of PM. We also highlight the new insights gained from those findings and suggest future directions for further advancing our understanding of PM pollution in China via real-time chemical characterization.

With its immense population and as the largest developing country in the world, China has made remarkable achievements in health promotion at a relatively low cost. However, China is still faced with challenges such as changes of disease spectrum, the coming era of an aging society, and the risk of environmental pollution. On October 25, 2016, China formally passed the blueprint of "Healthy China 2030," working towards the national goal of reaching a health standard on par with developed countries by 2030, which was also a response to realize the 2030 United Nations Sustainable Development Goals. "Healthy China 2030" is comprised of 29 chapters that cover five health areas. China is sparing no effort to transfer from being merely the most populous country, to becoming a leading nation in health education. In "Healthy China 2030," collaborated construction and resource sharing were clearly stated as the core strategy. A shift in concentration towards coordinated development of health-based economy from a previous pursuit of rapid economic growth was also underlined. There are also several major issues, such as severely aging population, the burden of chronic diseases, the insufficiency of health expenditure, and the great demand on health protection, waiting to be dealt with during the implementation process of "Healthy China 2030". "Healthy China 2030" is a momentous move to enhance public health, which is also a response to the global commitments. We also need to rethink our approach to reach the living standards and maintain a better environment.

With one-fifth of the world's total population, China's prevention and control of cardiovascular disease (CVD) may affect the success of worldwide efforts to achieve sustainable CVD reduction. Understanding China's current cardiovascular epidemic requires awareness of the economic development in the past decades. The rapid economic transformations (industrialization, marketization, urbanization, globalization, and informationalization) contributed to the aging demography, unhealthy lifestyles, and environmental changes. The latter have predisposed to increasing cardiovascular risk factors and the CVD pandemic. Rising CVD rates have had a major economic impact, which has challenged the healthcare system and the whole society. With recognition of the importance of health, initial political steps and national actions have been taken to address the CVD epidemic. Looking to the future, we recommend that 4 priorities should be taken: pursue multisectorial government and nongovernment strategies targeting the underlying causes of CVD (the whole-of-government and whole-of-society policy); give priority to prevention; reform the healthcare system to fit the nature of noncommunicable diseases; and conduct research for evidence-based, low-cost, simple, sustainable, and scalable interventions. By pursuing the 4 priorities, the pandemic of CVD and other major noncommunicable diseases in China will be reversed and the global sustainable development goal achieved. © 2016 American Heart Association, Inc.

In January 2013, North China Plain experienced several serious haze events. Cimel sunphotometer measurements at seven sites over rural, suburban and urban regions of North China Plain from 1 to 30 January 2013 were used to further our understanding of spatial-temporal variation of aerosol optical parameters and aerosol radiative forcing (ARF). It was found that Aerosol Optical Depth at 500 nm (AOD500nm) during non-pollution periods at all stations was lower than 0.30 and increased significantly to greater than 1.00 as pollution events developed. The Angstrom exponent (Alpha) was larger than 0.80 for all stations most of the time. AOD500nm averages increased from north to south during both polluted and non-polluted periods on the three urban sites in Beijing. The fine mode AOD during pollution periods is about a factor of 2.5 times larger than that during the non-pollution period at urban sites but a factor of 5.0 at suburban and rural sites. The fine mode fraction of AOD675nm was higher than 80% for all sites during January 2013. The absorption AOD675nm at rural sites was only about 0.01 during pollution periods, while 0.03-0.07 and 0.01-0.03 during pollution and non-pollution periods at other sites, respectively. Single scattering albedo varied between 0.87 and 0.95 during January 2013 over North China Plain. The size distribution showed an obvious tri-peak pattern during the most serious period. The fine mode effective radius in the pollution period was about 0.01-0.08 microns larger than during nonpollution periods, while the coarse mode radius in pollution periods was about 0.06-0.38 microns less than that during nonpollution periods. The total, fine and coarse mode particle volumes varied by about 0.06-0.34 cu microns, 0.03-0.23 cu microns, and 0.03-0.10 cu microns, respectively, throughout January 2013. During the most intense period (1-16 January), ARF at the surface exceeded -50W/sq m, -180W/sq m, and -200W/sq m at rural, suburban, and urban sites

This paper provides an overview of prototyping research activities of automatically switched optical networks and transport networks (ASONs/ASTNs) in China. In recent years, China has recognized the importance and benefits of the emerging ASON/ASTN techniques. During the period of 2001 and 2002, the national 863 Program of China started the preliminary ASON research projects with the main objectives to build preliminary ASON testbeds, develop control plane protocols and test their performance in the testbeds. During the period of 2003 and 2004, the 863 program started ASTN prototyping equipment projects for more practical applications. Totally 12 ASTN equipments are being developed by three groups led by Chinese venders: ZTE with Beijing University of Posts and Telecommunications (BUPT), Wuhan Research Institute of Posts and Telecommunication (WRI) with Shanghai Jiao Tong University (SJTU), and Huawei Inc. Meanwhile, as the ASTN is maturing, some of the China"s carries are participating in the OIF"s World Interoperability Demonstration, carrying out ASTN test, or deploying ASTN backbone networks. Finally, several ASTN backbone networks being tested or deployed now will be operated by the carries in 2005. The 863 Program will carry out an ASTN field trail in Yangtse River Delta, and finally deploy the 3TNET. 3TNET stands for Tbps transmission, Tbps switching, and Tbps routing, as well as a network integrating the above techniques. A task force under the "863" program is responsible for ASTN equipment specifications and interoperation agreements, technical coordination among all the participants, schedule of the whole project during the project undergoing, and organization of internetworking of all the equipments in the laboratories and field trials.

Full Text Available Open burning of straw in China has degraded agricultural environments and has become a contributor to air pollution. Development of efficient straw-reuse technologies not only can yield economic benefits but also can protect the environment and can provide greater benefit to society. Thus, the overall benefits of straw-reuse technologies must be considered when making regional development planning and enterprise technology decisions. In addition, agricultural areas in China cross several climatic zones and have different weather characteristics and cultural conditions. In the present study, we assessed five types of straw-reuse technologies (straw-biogas production, -briquetting, -based power generation, -gasification, and -bioethanol production, using emergy analysis, in northeast China. Within each type, five individual cases were investigated, and the highest-performing cases were used for comparison across technologies. Emergy indices for comprehensive benefits for each category, namely, EYR, ELR, and ESI were calculated. Calculated indices suggest that straw-briquetting and -biogas production are the most beneficial technologies in terms of economy, environmental impact, and sustainability compared to straw-based power generation, -gasification, and -bioethanol production technologies. These two technologies can thus be considered the most suitable for straw reuse in China.

This paper presents a theoretical model of nonlinear optical properties for strip plasmonic waveguides. The particular waveguides geometry that we investigate contains a gold core, adhesion layers, and silicon dioxide cladding. It is shown that the third-order susceptibility of the gold core...... significantly depends on the layer thickness and has the dominant contribution to the effective third-order susceptibility of the long-range plasmon polariton mode. This results in two nonlinear optical effects in plasmonic waveguides, which we experimentally observed and reported in [Opt. Lett. 41, 317 (2016...... approaches.

China's urban population surpassed its rural population historically in 2011, when the number of Chinese living in towns and cities reached about 690 million1. In the years to come, cities in China will face major challenges as their rapidly increasing populations burden already crowded infrastructure systems and exacerbate environmental and climate change issues, threatening public health and quality of life. Low-carbon cities may be key to addressing those challenges, especially as regards mitigating and adapting to climate change. Government entities at both the central and local level have moved aggressively on building low-carbon eco-cities. According to statistics reported by the Chinese Society for Urban Studies, by February of 2011, China will have 230 cities at the prefecture-and-above level that have proposed to establish themselves as “eco-cities,” accounting for 80.1% of the 287 such cities nationally. Of those 230 cities, 133, or 46.3%, have established targets to develop specifically as “lowcarbon cities” (Chinese Society for Urban Studies 2011). Given the proposed scale of the effort, China’s potential success or failure in demonstrating and implementing low-carbon eco-cities could greatly affect how the world addresses both the climate change impacts of urbanization and the sustainable development of cities. Despite the multiple guidelines that have been developed, it remains unclear what defines a low-carbon eco-city. Additionally, although more than 100 indicators have been used or proposed for assessing such cities, few relate directly to energy use or carbon emissions. Nonetheless, policy makers and leaders continue to demand comprehensive toolboxes to facilitate development of low-carbon eco-cities. This paper presents the results of an extensive literature review of the development of low-carbon eco-cities in China. The paper also qualitatively and quantitatively analyzes 11 major indicator systems that researchers, planners

Frailty in older adults predicts dependence and mortality and is a major challenge for healthcare systems in countries with rapidly aging populations. Little is known about frailty in China. We investigated the prevalence and associated risk factors of frailty in older adults in China. Cross-sectional. Data were obtained from the China Comprehensive Geriatric Assessment Study, conducted in 2011-12, which was the first uniform comprehensive assessment system adopted in China. Older adults from 7 cities were selected based on well-established cluster, stratification, and random selection statistical sampling techniques (N = 5,844). The Comprehensive Geriatric Assessment-Frailty Index was measured based on demographic characteristics, physical health, physical function, living behavior and social function, mental health, and cognitive function. The overall weighted prevalence of frailty was 9.9%: 12.7% in southwestern China, 11.0% in northern China, 5.9% in northwestern China, 5.0% in south-central China, 2.5% in eastern China, and 2.3% in northeastern China. The prevalence of frailty increased with age and was significantly higher in women and those living in rural areas. After adjusting for sex, age, area, region, and education, activity of daily living impairment was the strongest risk factor for frailty. Chronic diseases, depression, poor lifestyle, and geriatric syndromes were also independent risk factors. Our study provides epidemiological characteristics and the risk factors of frailty in China; the findings indicate greater regional disparities. Efforts to promote physical, psychological, and social health in older adults are a core objective of health policy, especially in women and those living in rural areas. © 2017, Copyright the Authors Journal compilation © 2017, The American Geriatrics Society.

The work of the theoretical study and numerical simulation of optical klystron free electron laser is supported by National 863 Research Development Program and National Science Foundation of China. The object of studying UV band free electron laser (FEL) is to understand the physical law of optical klystron FEL and to gain experience for design. A three-dimensional code OPFEL are made and it is approved that the code is correct completely. The magnetic field of the optical klystron, the energy modulation of the electron beam, the density modulation of the electron beam, spontaneous emission of the electron beam in optical klystron, the harmonic super-radiation of the electron beam, and the effects of the undulator magnetic field error on modulation of the electron beam energy are simulated. These results are useful for the future experiments

Full Text Available Corporate social responsibility is reflected in environmental, social, economic, stakeholder and voluntariness dimensions. It had become an important topic for European agenda where CSR is considered as a concept whereby companies integrate social and environmental concerns in their business operations and interact with stakeholders on a voluntary basis. In general, it is the responsibility of enterprises for their impact on society. CSR and its certification is important not only for EU but also for out-European business partners such as China. This paper is focused on EU agenda related to CSR, certification, SA8000 standard and the case study of China in relation to SA8000. The results show that the interest in obtaining of SA8000 certificate has risen up to 3231 companies in 2013. European certified companies are represented by 1583 in 2013. The most developing regions in terms of SA8000 certification are Europe and Central Asia, resp. Europe, South Asia and East Asia and the Pacific. In Europe, the most SA8000 certified country is Italy with one third of certifications from the whole world. From out- European countries leading role is taken by India and China. China is the world biggest exporter in the apparel branch which has also the highest number of SA8000 certified companies.

A centralized optical processing unit (COPU) that functions both as a wavelength converter (WC) and optical burst equaliser in a 10 Gb/s wavelength-converting optical access network is proposed and experimentally characterized. This COPU is designed to consolidate drifting wavelengths generated with an uncooled laser in the upstream direction into a stable wavelength channel for WDM backhaul transmission and to equalize the optical loud/soft burst power in order to relax the burst-mode receiver dynamic range requirement. The COPU consists of an optical power equaliser composed of two cascaded SOAs followed by a WC. Using an optical packet generator and a DC-coupled PIN-based digital burst-mode receiver, the COPU is characterized in terms of payload-BER for back-to-back and backhaul transmission distances of 22, 40, and 62 km. We show that there is a compromise between the receiver sensitivity and overload points that can be optimized tuning the WC operating point for a particular backhaul fiber transmission distance. Using the optimized settings, sensitivities of -30.94, -30.17, and -27.26 dBm with overloads of -9.3, -5, and >-5 dBm were demonstrated for backhaul transmission distances of 22, 40 and 62 km, respectively. © 2011 Optical Society of America

Future Hegemonic Rivalry Between China and the West?

Directory of Open Access Journals (Sweden)

Erich Weede

1995-08-01

Full Text Available Currently there is a unipolar distribution of power. The United States reigns supreme. Russia's economic power will remain insufficient to underwrite a renewed attempt to establish global leadership. While the European Community still commands sufficient resources for exercising global leadership, it lacks the political foundation for unitary action. Moreover, the European addiction to the welfare state undermines European competitiveness. Japan is too much of a "trading state" and unlikely to become a first-rate military power, before she is overtaken by China in economic size. So, count Russia, Europe and Japan out as conceivable challengers to United States hegemony. China is the only plausible candidate. Its economic growth rate is nothing less than spectacular. Moreover, the Chinese government seems capable of extracting the necessary resources for waging a hegemonic rivalry from a society that is likely to remain quite poor for at least another generation. There are a number of conceivable scenarios for the emerging American-Chinese relationship. The future will depend on the relative speed of the American decline and the rise of China as well as on the openness of the global economy. The more open the global economy, the better the prospects for rising per capita incomes in China become, the better the prospects for some mellowing or even democratization of the Chinese regime. Only if the West sticks together under American leadership and if creeping capitalism in China leads to creeping democratization later, is hegemonic rivalry likely to remain benign and peaceful.

Over the past two decades in China,stress on the environment has increased continuously.This paper will assess the change in environmental quality over time,and its spatial variation using data from the statistical yearbooks of 31 provincial administrative regions in 1990,1995,2000,2005,and 2010.These books provide a general assessment of the environment at the provincial level,and the three major economic regions from western to eastern China.By using the geographic information system (GIS) and SPSS,we analyzed the changing trend of China's eco-environment and calculated the changing trajectory in the gravity center of the eco-environmental quality.We conclude the following.(1) From 1990 to 2010,the rate of deterioration of the environment went down.We argue that the cause of this trend was neither the result as “the deterioration trend was under control” noticed by the government departments concerned,nor “the deterioration rate of the environment was increasingly intensified” suggested by many researchers.(2) Since 1990,the general environment has been worsening in China,but it was improved in some regions; however,the ecological deficit is still expanding and will last for a long time.(3) From western to eastern China,the deterioration rate of environmental quality was slowed down.The reasons include a good natural environment,a developed regional economy,and technology and finance in eastern China.(4) After extensive economic development in China,there are imbalances of population,economy,society,and the environment in the 31 provincial regions.The governments at all levels should play an important role in research and protecting the environment.In addition,it is imperative to implement positive measures such as controlling population,improving the environment,and promoting smart development to balance the socio-ecological system.

SONG is a global ground-based network of 1m telescopes for stellar time-domain science, an international collaboration involving many countries across the world. In order to enable a favorable duty cycle, the SONG network plans to create a homogeneous distribution of four nodes in each of the northern and southern hemispheres. An expected possibility was building one of the northern nodes in East Asia, preferably on the Qinghai-Tibetan Plateau. During the last decade, a great deal of effort has been invested in searching for a high-quality site for ground-based astronomy in China, since this has been one of the major concerns for the development of Chinese astronomy. A number of sites on the plateau have been in operation for many years, but most of them are used only for radio astronomy, as well as small optical telescopes that are used for applied astronomy. Several potential sites for large optical instruments have been identified by the plateau site survey, but so far none of them have been adequately quantitatively characterized. Here we present results from a detailed multi-year study of the Delingha site, which was eventually selected for the SONG-China node. We also describe the site-monitoring system that will allow an isolated SONG and 50BiN node to operate safely in an automated mode.

Comparison between iterative wavefront control algorithm and direct gradient wavefront control algorithm for adaptive optics system

Among all kinds of wavefront control algorithms in adaptive optics systems, the direct gradient wavefront control algorithm is the most widespread and common method. This control algorithm obtains the actuator voltages directly from wavefront slopes through pre-measuring the relational matrix between deformable mirror actuators and Hartmann wavefront sensor with perfect real-time characteristic and stability. However, with increasing the number of sub-apertures in wavefront sensor and deformable mirror actuators of adaptive optics systems, the matrix operation in direct gradient algorithm takes too much time, which becomes a major factor influencing control effect of adaptive optics systems. In this paper we apply an iterative wavefront control algorithm to high-resolution adaptive optics systems, in which the voltages of each actuator are obtained through iteration arithmetic, which gains great advantage in calculation and storage. For AO system with thousands of actuators, the computational complexity estimate is about O(n2) ˜ O(n3) in direct gradient wavefront control algorithm, while the computational complexity estimate in iterative wavefront control algorithm is about O(n) ˜ (O(n)3/2), in which n is the number of actuators of AO system. And the more the numbers of sub-apertures and deformable mirror actuators, the more significant advantage the iterative wavefront control algorithm exhibits.

Full Text Available Construction industrialization (CI has been adopted worldwide because of its potential benefits. However, current research shows the incentives for adopting CI may differ in different regions. While the promotion of CI in China is still at the initial stage, a systematical analysis of the driving factors would help decision makers get a comprehensive understanding of CI development and select proper strategies to promote CI. This research combines qualitative and quantitative methods to explore the construction industrialization driving factors (CIDFs in China. The grounded theory method (GTM was employed to explore CI concepts among 182 CI-related articles published in 10 top-tier journals from 2000 to 2017. A total of 15 CIDFs were identified, including one suggested by professionals during a pre-test questionnaire survey. The analysis showed that the development of CI in China is pushed by macrodevelopment and pulled by the government and is also a self-driven process. The major driving factors for CI adoption in China are the transformation and upgrade of the conventional construction industry and the solution of development dilemmas. Our study also suggests that pilot programs are, currently, the most effective method to promote CI in China and to accumulate experience so to gain recognition by the society. This research is also of value for CI promotion in other developing countries.

Ephemeral China/Handmade China

Xing Ruan

2014-07-01

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

Women in Physics in a Rapidly Changing China

Wu, Ling-An

2008-03-01

Despite the upheavals of the 20th century, physics managed to survive quite well in China, where the first woman president of the American Physical Society was born and bred. During the 1950s as a result of policies that emphasized science and engineering, declared equal rights and equal pay for men and women, and assigned jobs to college graduates irrespective of sex, the number of women in physics increased rapidly, many of whom made notable achievements. Since China's opening up over the last thirty years tremendous changes have taken place, and women now face new opportunities as well as challenges in all aspects of society. Whereas physics used to be regarded as the most elite of the sciences, new fields such as computer science, biotechnology and business are now competing for the best students. Compared with other countries the statistics are not bad; in schools and many physics departments the ratio of women teachers may be 30% or higher, but the numbers drop drastically with rank. Moreover, in some research institutions the ratio of female physicists is actually declining, due to retirement of the older generation and fewer successors. Compulsory retirement for women at an earlier age than for men is also a new factor. Conversely, in recent years the ratio of female graduate students enrolling in physics has increased, even reaching 40% in some universities. However, the reasons for this do not bode well: men are not performing so well as women in entrance exams, while the latter are facing increasing discrimination in employment so they have to seek higher degree qualifications. With the further development of China's economy there will be abundant demand for qualified personnel including women with a physics background. It is imperative to actively support the upcoming generation of women physicists and not lose them in the leaky pipeline. The Chinese Physical Society has taken certain positive steps, such as the recent establishment of the Xie Xi

Proposal for a Northeast Asian Hydrogen Highway: From a Natural-gas-based to a Hydrogen-based Society

In Northeast Asia, East Siberia and Sakhalin are rich in natural gas (NG). The environmental protection and energy security of the Northeast Asian region requires constructing an energy infrastructure network that can transport and distribute NG throughout the region in the near term, and renewable-source gaseous hydrogen (GH2) in the long term. We have promoted the construction of an NG pipeline network, the principal component of the energy infrastructure essential to our evolution toward a hydrogen-based society, through the Northeast Asia Natural Gas and Pipeline Forum (NAGPF). Our ultimate goal is a clean and sustainable society based on renewable energy sources, wherein hydrogen is produced from the vast potential of renewable energy in Siberia and China. The hydrogen thus produced would be transmitted through the pipeline network, progressively replacing NG as it is depleted. Over three-quarters of commercially exploitable hydroelectric power (hydro) resources of all Russia is in East Siberia. The areas from Kamchatka through the Kurilskiye Islands (called the Chishima Islands, in Japan) to Sakhalin is a world-class wind energy resource. West China has huge potential for solar energy.

With the rapid development of China's economy and high rate of industrialization, environmental pollution has become a major challenge for the country. The present study is aimed at analyzing spatiotemporal heterogeneities and changes in trends of different aerosol optical properties observed over China. To achieve this, Collection 6 Level 3 data retrieved from the Moderate Resolution Imaging Spectroradiometer (MODIS; 2002-2016) and Ozone Monitoring Instrument (OMI; 2005-2016) sensors were used to investigate aerosol optical depth (AOD 550 ), Ångstrӧm exponent (AE 470-660 ), and Absorption Aerosol Index (AAI). The spatial distribution of annual mean AOD 550 was noticed to be high over economically and industrialized regions of the east, south, and northeast of China, while low aerosol loadings were located over rural and less-developed areas of the west and northeast of China. High AE 470-660 (> 1.0) values were characterized by the abundance of fine-mode particles and vice versa, likely attributed to large anthropogenic activities. Similarly, high AOD with corresponding high AE and low AAI was characterized over the urban-industrialized regions of the central, east, and south of China during most of the months, being more pronounced in June and July. On seasonal scale, AOD values were found to be high during spring, followed by the summer and autumn, and low during the winter season. It is also evident that all aerosol parameters showed a single-peak frequency distribution in all seasons over entire China. Further, the annual, monthly, and seasonal spatial trends revealed a decreasing trend in AOD over most regions of China, except in the southwest of China, which showed a positive increasing trend. Significant increasing trends were noted in AAI for all the seasons, particularly during autumn and winter, resulting in a large amount of the absorbing type of aerosols produced from biomass burning and desert dust.

The development of quantum optics was part and parcel of the formation of modern physics following the fundamental work of Max Planck and Albert Einstein, which gave rise to quantum mechanics. The possibility of working with pure quantum objects, like single atoms and single photons, has turned quantum optics into the main tool for testing the fundamentals of quantum physics. Thus, despite a long history, quantum optics nowadays remains an extremely important branch of physics. It represents a natural base for the development of advanced technologies, like quantum information processing and quantum computing. Previous Central European Workshops on Quantum Optics (CEWQO) took place in Palermo (2007), Vienna (2006), Ankara (2005), Trieste (2004), Rostock (2003), Szeged (2002), Prague (2001), Balatonfüred (2000), Olomouc (1999), Prague (1997), Budmerice (1995, 1996), Budapest (1994) and Bratislava (1993). Those meetings offered excellent opportunities for the exchange of knowledge and ideas between leading scientists and young researchers in quantum optics, foundations of quantum mechanics, cavity quantum electrodynamics, photonics, atom optics, condensed matter optics, and quantum informatics, etc. The collaborative spirit and tradition of CEWQO were a great inspiration and help to the Institute of Physics, Belgrade, and the Serbian Academy of Sciences and Arts, as the organizers of CEWQO 2008. The 16th CEWQO will take place in 2009 in Turku, Finland, and the 17th CEWQO will be organized in 2010 in St Andrews, United Kingdom.

Optic perineuritis is an uncommon inflammatory disorder that involves optic nerve sheath. Numerous case reports have been published on optic perineuritis in adults, the majority of whom had bilateral presentation. There are limited data on optic perineuritis occurring in pediatric patients. We report a teenager who presented with a unilateral sign that mimicked the presentation of optic neuritis. The orbit and brain magnetic resonance imaging confirmed features of unilateral optic perineuritis. She was treated with a high dose of corticosteroids for 2weeks, and her final visual outcome was satisfactory. No signs of relapse were noted during follow-up visits.

Full Text Available In this article, the author presents an empirical study of sustainable banking in China and examines the flagship China DevelopmentBank (CDB. The CDB is directly supervised by the State Council of the People’s Republic of China and is one ofthe largest state-owned financial institutions in the country. Its overseas lending is growing rapidly; it increasingly acts as aglobal player, influenced by a variety of international actors. Using the mercantilist framework, the author investigates how the CDB’s social policies diverge from those set by the Chinese authorities. The analysis discusses CDB’s policy variations that are not in line with government interests or prescribed directly by governmental bodies. It concludes that the bank has been active in developing and establishing its own corporate strategy for implementing the concept of sustainable development to promote a balanced development of the economy, society and the environment. That strategy contains the norms and rules set by Chinese regulatory agencies with regard to social and environmental areas, as well as important elements ofthe international practice of corporate responsibility and sustainable funding. The CDB is most likely driven by its desire tobe considered internationally a good corporate citizen and often acts independently from governmental guidance, which insome sense undermines mercantilist perceptions.

Social trust, interpersonal trust and self-rated health in China: a multi-level study.

Science.gov (United States)

Feng, Zhixin; Vlachantoni, Athina; Liu, Xiaoting; Jones, Kelvyn

2016-11-08

Trust is important for health at both the individual and societal level. Previous research using Western concepts of trust has shown that a high level of trust in society can positively affect individuals' health; however, it has been found that the concepts and culture of trust in China are different from those in Western countries and research on the relationship between trust and health in China is scarce. The analyses use data from the national scale China General Social Survey (CGSS) on adults aged above 18 in 2005 and 2010. Two concepts of trust ("out-group" and "in-group" trust) are used to examine the relationship between trust and self-rated health in China. Multilevel logistical models are applied, examining the trust at the individual and societal level on individuals' self-rated health. In terms of interpersonal trust, both "out-group" and "in-group" trust are positively associated with good health in 2005 and 2010. At the societal level, the relationships between the two concepts of trust and health are different. In 2005, higher "out-group" social trust (derived from trust in strangers) is positively associated with better health; however, higher "in-group" social trust (derived from trust in most people) is negatively associated with good health in 2010. The cross-level interactions show that lower educated individuals (no education or only primary level), rural residents and those on lower incomes are the most affected groups in societies with higher "out-group" social trust; whereas people with lower levels of educational attainment, a lower income, and those who think that most people can be trusted are the most affected groups in societies with higher "in-group" social trust. High levels of interpersonal trust are of benefit to health. Higher "out-group" social trust is positively associated with better health; while higher "in-group" social trust is negatively associated with good health. Individuals with different levels of educational

Introduction to "Islam in China/China in Islam"

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...

In China, regional haze pollution is a serious environmental problem. The impact on ecosystem, however, is not clearly understood. This study investigates the effect of regional haze pollution on the yields of rice and wheat in China. The spatial and temporal distributions of aerosol optical depth (AOD) show high particulate pollution in the North China Plain region, Yangtze River Delta region, the central eastern China, and the Si Chuan Basin, coexisted largely with crop growth in time and space. The solar irradiance reaching these regions is estimated to reduce by up to 28-49%, calculated using the AOD distributions and tropospheric ultraviolet-visible (TUV) model. Reduction of solar irradiance in these regions can depress optimal yields of about 45% of rice and 75% of wheat growth in China, leading to 2% reduction in total rice production and 8% reduction in total wheat production in China. However, there are large uncertainties of the estimate related to the diffuse solar radiation. For high diffuse radiation case, the estimate reductions of rice and wheat decrease to 1% and 4.5%, respectively. A further detailed study is needed to clearly understand this effect to meet the growing food demand in the nation in the coming decades.

Motivations for Deceased Organ Donation Among Volunteers in China: A Qualitative Research Study.

Yin, Zhike; Liu, Shan; Yan, Jin; Liu, Jia

2016-06-09

BACKGROUND To align with guiding principles on human organ and tissue transplantation published by the World Health Organization (WHO), the Red Cross Society of China (RCSC) launched a new nationwide organ donation program in 2010 to recruit organ donation volunteers. Despite severe shortage of donated organs, there is a very low rate of volunteering for organ donation among the Chinese population (only 0.03 donors per million population) in the national program. Motivating organ donation is the key to the success of organ transplantation in China. MATERIAL AND METHODS Semi-structured 45- to 60-min interviews were conducted among 34 volunteers. Data analysis was performed with Nvivo 8.0 software. RESULTS Six motivations for organ donation were identified: helping others/altruism, fulfilling long-cherished wishes, reducing the burdens, making the best use of everything, giving back to society, and life extension. Factors affecting the motivation of organ donation among volunteers in China included traditional values, personal experiences, role model effect, family support, and problems in the donation system. Possible strategies to improve organ donation included fostering a scientific concept of the body and death, focusing donation promotion efforts on certain groups, and simplifying the process of organ donation. CONCLUSIONS There are multiple reasons for Chinese people to register for organ donation, with helping others as the central motivation.

The relative stability of prehistorical geographic environment in China's tropics on the basis of archaeology

According to archaeological data from about sixty samples the relative stability ofphysical and human geographical environment in the tropical zone of China is discussed in thispaper. Because of the superior natural environment, sufficient food resources and a sparsepopulation resulting in the absence of social requirement to transform the productive forces, theadvancement of economy and society was stagnated during prehistorical period in China's tropics.Compared with northern China, the appearance of ground stone tool stagnated about 3,000 years,the beginning of Bronze Age, about 1,000 years, and the agriculture, 2,500-3,000 years. The noceramics age continued till the early Neolithic Age and the appearance of colour or white ceramicswas 2,000 years later than that in northern China. The life form of migration to gather and to huntcontinued till the middle Neolithic Age, and the fixed settlement based on agriculture 1,000-2,000years stagnated. The clan commune just appeared at the end of the Neolithic Age which was 2,000-3,000 years later than that in northern China.

Garber, Paul A

2018-01-24

Over the past few decades, field studies conducted by Chinese primatologists have contributed significant new theoretical and empirical insights into the behavior, ecology, biology, genetics, and conservation of lorises, macaques, langurs, snub-nosed monkeys, and gibbons. With the recent establishment and inaugural meeting of the China Primatological Society in 2017, China has emerged as a leading nation in primate research. Several research teams have conducted long-term studies despite the difficult challenges of habituating and observing wild primates inhabiting mountainous temperate forests, and the fact that some 80% of China's 25-27 primate species are considered vulnerable, endangered, or critically endangered and are distributed in small isolated subpopulations. In going forward, it is recommended that primatologists in China increase their focus on seasonal differences in the social, ecological, physiological, and nutritional challenges primates face in exploiting high altitude and cold temperate forests. In addition, provisioning as a habitation tool should be minimized or eliminated, as it is difficult to control for its effects on group dynamics, patterns of habitat utilization, and feeding ecology. Finally in the next decade, Chinese primatologists should consider expanding the taxonomic diversity of species studied by conducting research in other parts of Asia, Africa, and the Neotropics.

This paper reports on the reason for China's future nuclear policy. First, assuming a continued decline in superpower influence, China's focus will be on regional issues. The policies of Japan, the NICs and other Chinese neighbors will be more relevant than those of the superpowers. Second, Chinese domestic politics will have to resume the road to reform. A more unstable and suspicious Chinese leadership will perceive a more hostile and unstable world. Even when China was on the path to reform, its foreign relations were not always peaceful. However, it would be wrong to suggest that even a more xenophobic and unstable Chinese leadership would necessarily expand China's nuclear capability or lead China into a major war. Even at the height of the Cultural Revolution, Chinese foreign policy was careful, nuclear proliferation was avoided and crises were well-managed. Still China's basic domestic and foreign policy needs will likely remain unfulfilled for the foreseeable future. Furthermore, although the East Asian balance of power may not appear to be particularly dangerous at present, there is enough uncertainty to ensure that China remains a nuclear power and a maverick one at that at least in the near term

Tobacco as a social currency: cigarette gifting and sharing in China.

Rich, Zachary C; Xiao, Shuiyuan

China produces and consumes more tobacco than any other country in the world and as such is at the forefront of the world tobacco epidemic. Many studies have recently emerged that directly or indirectly reference the acts of giving and sharing cigarettes as a major contributor to China's high tobacco usage. The goal of this report is to review relevant literature relating to sharing and gifting cigarettes as well as provide useful historic and cultural contexts. Important differences between the act of giving individual cigarettes and the gifting of packaged cigarettes are explored as well as explanations for how both these practices have influenced current tobacco control efforts. Available Chinese and English sources on gifting and sharing cigarettes in China published between 1991 and 2011 were reviewed and discussed with a cultural and historical background. The practices of gifting and sharing cigarettes strongly contribute to smoking initiation as well as failure to quit smoking among Chinese males. Historical and cultural roots have reinforced these practices and hampered efforts to reduce tobacco use in China. Traditional tobacco control efforts should be combined with culture-specific approaches to reduce tobacco usage in China. The regular exchange of cigarettes normalizes smoking across society and promotes tobacco's acceptability. Great efforts should be taken not only to minimize these practices among males but also to discourage their adoption by females.

To evaluate the extent and quality of published pharmacoeconomic studies based in China. A systematic literature search was conducted using PubMed, Web of Science, Google Scholar, and China National Knowledge Infrastructure to identify pharmacoeconomic studies conducted in China. The keywords included different combinations of health economics, pharmacoeconomic, cost-effectiveness, and China. The inclusion criteria for the studies were: 1) original research articles; 2) written/published in English; 3) comparing a pharmaceutical to another pharmaceutical, treatment modality, or no treatment; and 4) conducted in China. The articles were reviewed by two independent reviewers using the 100-point Quality of Health Economic Studies scale for pharmacoeconomic studies. General and economic analysis information was collected from the articles. A total of 20 studies were included, which were published in 11 different journals between 2006 and 2012 and had an average of 5 ± 2 authors. The mean Quality of Health Economic Studies scale scores for pharmacoeconomic studies was 80 ± 10. More than two-thirds of the authors resided in China (70%) and most had a medical background (90%). Most studies were published in foreign journals (not based in China) (90%), conducted cost-effectiveness (65%) or cost-utility analyses (65%), and used modeling as their study design (80%). China-based pharmacoeconomic studies written in English are limited in number, but, on average, are of good quality. Economic evaluation of pharmaceuticals should be encouraged in China because appropriate allocation of health care resources is important in a country where, despite economic growth, resources remain scarce relative to needs.

Chen, Zhi Yun

2001-10-01

Infocom is a term used to describe the merger of Information and Communications and is used to show the radical changes in today's network traffic. The continuous growth of Infocom traffic, especially that of Internet, is driving Infocom networks to expand rapidly. To service providers, the traffic is consuming the bandwidth of their network. Simultaneously, users are complaining too slow, the net never stopped in China. It is the reality faced by both the service providers and equipment vendors. Demands from both the customers and competition in market call for an efficient network infrastructure. What should a Service Provider do? This paper will first analyze the development trends of optical networking and the formation of the concepts of Intelligent Optical Network (ION) and Automatic Switched Optical Network (ASON) as a solution to this problem. Next it will look at the ways to bring intelligence into optical networks, discussing the benefits to service providers by showing some application examples. Finally, it concludes that the development of optical networking has arrived at a point of introducing intelligence into optical networks. The intelligent optical networks and Automatic Switched Optical Networks will immediately bring a wide range of benefit to service providers, equipment vendors, and, of course, the end users.

Mistrust of physicians in China: society, institution, and interaction as root causes.

Science.gov (United States)

Chan, Cheris Shun-Ching

2018-03-01

Based on two years' ethnographic research on doctor-patient relations in urban China, this paper examines the causes of patients' mistrust of physicians. I identify the major factors at the societal, institutional, and interpersonal levels that lead to patients' mistrust of physicians. First, I set the context by describing the extent of mistrust at the societal level. Then, I investigate the institutional sources of mistrust. I argue that the financing mechanism of public hospitals and physicians' income structures are the most crucial factors in inducing patients' mistrust. Hospitals' heavy reliance on self-finance has basically caused public hospitals to run like private hospitals, resulting in blatant conflicts of interest between hospitals and patients. Related to this is physicians' reliance on bonuses and commissions as part of their regular incomes, which has inevitably resulted in overtreatment and, hence, mistrust from the patients. At the interpersonal level, I describe how individual physicians' attitudes toward and interaction with patients may also affect patients' sense of trust or mistrust in physicians. In conclusion, I discuss the ethical implications of the mistrust problem, and suggest changes at the institutional and interpersonal levels to mitigate the problem. © 2017 John Wiley & Sons Ltd.

An all-optical temporal fractional order differentiator with ultrabroad bandwidth (~1.6 THz) and extremely simple fabrication is proposed and experimentally demonstrated based on an in-fiber ellipsoidal air-microcavity. The ellipsoidal air-microcavity is fabricated by splicing a single mode fiber (SMF) and a photonic crystal fiber (PCF) together using a simple arc-discharging technology. By changing the arc-discharging times, the propagation loss can be adjusted and then the differentiation order is tuned. A nearly Gaussian-like optical pulse with 3 dB bandwidth of 8 nm is launched into the differentiator and a 0.65 order differentiation of the input pulse is achieved with a processing error of 2.55%. Project supported by the the National Natural Science Foundation of China (Nos. 61522509, 61377002, 61535012), the National High-Tech Research & Development Program of China (No. SS2015AA011002), and the Beijing Natural Science Foundation (No. 4152052).

Hou Yu; Zhang Tianzhu

2009-01-01

Lessons learnt from accidents are essential sources for updating state-of-the-art requirements in pollution accident prevention. To improve this input in the People's Republic of China in a systematic way, a database for collecting and evaluating major pollution accidents is being established. This is being done in co-operation with Chinese Society for Environment Sciences and other national Institutions. At the time of writing over 80 major events from 2002-2006 have been collected. In this paper, a summary evaluation on the major polluting events in China from 2002 to 2006 is presented and some basic lessons drawn shown. There is no a systematic pollution accident notification system currently in China. The results from root cause analysis underline the importance of emergency measures, maintenance, human factor issues and the role of safety organization. Chronic pollution, especially water pollution and air pollution should be paid the same attention as the sudden pollution. It is important to keep in mind that collecting information from major accidents represents a small percentage of the actual number of events taking place.

For 20 years, China has participated in 267 international cooperation projects against the HIV/AIDS epidemic and received ∼526 million USD from over 40 international organizations. These projects have played an important role by complementing national efforts in the fight against HIV/AIDS in China. The diverse characteristics of these projects followed three phases over 20 years. Initially, stand-alone projects provided technical support in surveillance, training or advocacy for public awareness. As the epidemic spread across China, projects became a part of the comprehensive and integrated national response. Currently, international best practices encourage the inclusion of civil society and non-governmental organizations in an expanded response to the epidemic. Funding from international projects has accounted for one-third of the resources provided for the HIV/AIDS response in China. Beyond this strong financial support, these programmes have introduced best practices, accelerated the introduction of AIDS policies, strengthened capacity, improved the development of grassroots social organizations and established a platform for communication and experience sharing with the international community. However, there are still challenges ahead, including integrating existing resources and exploring new programme models. The National Centre for AIDS/STD Control and Prevention (NCAIDS) in China is consolidating all international projects into national HIV prevention, treatment and care activities. International cooperation projects have been an invaluable component of China's response to HIV/AIDS, and China has now been able to take this information and share its experiences with other countries with the help of these same international programmes.

Religious Renaissance in China Today

Directory of Open Access Journals (Sweden)

Richard Madsen

2011-01-01

Full Text Available Since the beginning of the Reform Era in 1979, there has been a rapid growth and development of religious belief and practice in China. A substantial new scholarly literature has been generated in the attempt to document and understand this. This essay identifies the most important contributions to that literature and discusses areas of agreement and controversy across the literature. Along with new data, new paradigms have developed to frame research on Chinese religions. The paradigm derived from C. K. Yang’s classic work in the 1960s came from structural functionalism, which served to unite research in the humanities and social sciences. However, structural functionalism has been abandoned by the new generation of scholars. In the humanities, the most popular paradigm derives from Michel Foucault, but there are also scholars who use neo-Durkheimian and neo-Weberian paradigms. In the social sciences, the dominant paradigms tend to focus on state-society relations. None of these paradigms fully captures the complexity of the transformations happening in China. We recommend greater dialogue between the humanities and social sciences in search of more adequate theoretical frameworks for understanding Chinese religions today.

Climatic Change, Wars and Dynastic Cycles in China Over the Last Millennium

In recent years, the phenomenon of global warming and its implications for the future of the human race have been intensively studied. In contrast, few quantitative studies have been attempted on the notable effects of past climatic changes upon human societies. This study explored the relationship between climatic change and war in China by comparing high-resolution paleo-climatic reconstructions with known war incidences in China in the last millennium. War frequencies showed a cyclic pattern that closely followed the global paleo-temperature changes. Strong and significant correlations were found between climatic change, war occurrence, harvest level, population size and dynastic transition. During cold phases, China suffered more often from frequent wars, population decline and dynastic changes. The quantitative analyses suggested that the reduction of thermal energy input during a cold phase would lower the land carrying capacity in the traditional agrarian society, and the population size, with significant accretions accrued in the previous warm phase, could not be sustained by the shrinking resource base. The stressed human-nature relationship generated a 'push force', leading to more frequent wars between states, regions and tribes, which could lead to the collapse of dynasties and collapses of human population size. War frequencies varied according to geographical locations (North, Central and South China) due to spatial variations in the physical environment and hence differential response to climatic change. Moreover, war occurrences demonstrated an obvious time lag after an episode of temperature fall, and the three geographical regions experienced different length of time lags. This research also shows that human population increases and collapses were correlated with the climatic phases and the social instabilities that were induced by climate changes during the last millennium. The findings proposed a new interpretation of human

China has become the world's largest producer and consumer of tobacco and lung cancer is China's leading cause of cancer deaths. The large majority of Chinese smokers are men. Tobacco consumption is of particular concern among China's internal floating (or migrant) population, which has become a permanent feature of Chinese society, because this population is very large (over 100 million persons) and it has a high prevalence of smoking. Considering additionally that like the general population of China, the smoking prevalence rate of women from this group is quite low, we therefore aimed to explore smoking-related knowledge, attitudes and behaviours among male smokers in the floating population to help inform the development of effective smoking cessation interventions in this important target group in China. We interviewed 39 floating population male smokers in six focus groups and performed a qualitative content analysis of the interviews. Most participants knew that smoking is risky to health but they knew little about why. Habit and social participation were key drivers of smoking. Smoking was regarded as a core component of their identity by the urban residents. Some participants had tried to stop smoking but none reported having ever been educated about smoking. Smoking cessation interventions for China's male floating population would need to incorporate comprehensive education and information about why smoking is dangerous and the benefits of stopping.

The position, role and development prospects of nuclear energy in China energy system

The fundamental features of the present energy system of China are discussed and analyzed. and it is pointed out that since the founding of the People's Republic of China, although the energy construction, including the development and use of nuclear energy, has achieved great success, the average energy resource per capita is still low. The following major issues, such as the transportation pressure raised from the energy structure of taking coal as the main, the increasing seriousness of environmental pollution, large amount of greenhouse gases emission and low 'energy efficiency', etc., have constrained the sustainable development of national economy and society. In accordance with the position of nuclear energy in the strategy of the energy development in south-east coastal areas of China, and the analysis of 'value criteria' and 'decision goal' system for the development and use of nuclear energy, it is thought the development of nuclear energy is an important way and the optimum selection to optimize China's energy system. In accordance with the fundamental policy and technical line, and the technical ability and foundation conditions, the strategic target, scale and overall arrangement for the development of China's nuclear power are proposed and the bright future for the development of China's nuclear power industry is comprehensively discussed and analyzed.

Given the rapid demographic transition and obesity growth in China, it is important to study how the large only-child population (≈100 million) might contribute to the obesity epidemic. This study evaluated associations of only-child status with weight and energy expenditure-related behaviors in China and examined how the associations may vary by sex and urbanicity. Secondary analyses of nationally representative cross-sectional data from China Education Panel Survey: Junior Cohorts 2013-14, which included 19,487 students from 112 middle schools in 28 regions across China. We used propensity-score-weighted multilevel models to test associations between only-child status and weight outcomes.

The transmission route of TCM knowledge in ancient China primarily included doctor's transmission and non-doctor's transmission. The doctor's transmission mode included lineage-teaching system, elementary study system, transmission between schools and the clinical effects on the society etc. Non-doctor's transmission mode included literati's interests, literati's sickness, literati's health cultivation, the interests of top society, literati's recoding etc. Different transmission modes played an important role in the transmission and conservation of TCM knowledge as well as a reference to developing the transmission of present-day TCM knowledge.

Different educational and professional developments within the dental field create different sets of missions, norms, and practices regarding dental diseases and their appropriate treatment. This review has addressed differences in dental education and professional development between mainland China and North America. Many factors influence the choice of model and it is very difficult to predict which model will become predominant. However, there is growing sentiment that the independent faculty model in North America is logical and superior to the model, which 'integrates' dental and medical education in mainland China. Many North America dental schools place a high priority on preclinical and clinical training in the curriculum in order to expose students to patient oral health needs and systemic dental problems much earlier than in mainland China. North America dental schools promote and embrace students self-learning skills by the use of PBL, CRL, and TRAD education methodologies and new e-based technologies and approaches whereby students learn rather than are taught. In mainland China, the traditional lecture-based format is still employed in the majority of dental schools; however, strategies to enhance students self-learning skills is increasingly utilised in most well-known Chinese dental schools. The Chinese dental education model, which treats dentistry as a sub-specialty of medicine, has brought about fundamental differences, with the dentist functioning essentially as a stomatologist. For example, China has built up a large oral and maxillofacial surgery society, and craniofacial surgery is performed to a much broader extent by Chinese dentists than by most North American counterparts. In North America, dentists engage in full-time work, attend continuing training/education programmes, belong to an association, gain legal status, and construct a code of ethics emphasising the quality of care delivered to the public. Currently, continuing dental

China has become a key player in the global nanotechnology field, however, no surveys have specifically examined safety practices in the Chinese nano-laboratories in depth. This study reports results of a survey of 300 professionals who work in research laboratories that handle nanomaterials in China. We recruited participants at three major nano-research laboratories (which carry out research in diverse fields such as chemistry, material science, and biology) and the nano-chemistry session of the national meeting of the Chinese Chemical Society. Results show that almost all nano-research laboratories surveyed had general safety regulations, whereas less than one third of respondents reported having nanospecific safety rules. General safety measures were in place in most surveyed nano-research laboratories, while nanospecific protective measures existed or were implemented less frequently. Several factors reported from the scientific literature including nanotoxicology knowledge gaps, technical limitations on estimating nano-exposure, and the lack of nano-occupational safety legislation may contribute to the current state of affairs. With these factors in mind and embracing the precautionary principle, we suggest strengthening or providing nanosafety training (including raising risk awareness) and establishing nanosafety guidelines in China, to better protect personnel in the nano-workplace.

The International Network for Genetic Evaluation of Rice (INGER) is a global partnership between international and national agricultural research institutions. INGER focuses on worldwide exchange, evaluation and utilization of improved varieties and elite breeding lines of rice. China has actively participated in the activities of INGER since 1980.During the pasted years, 26 500 INGER entries with diversity genetic background have been introduced and evaluated by Chinese scientists. Among of them, 37 commercial varieties directly from elite INGER entries and 27 rice hybrids using INGER lines as their restorer lines/donors have been released to farmers in China. About 1 900 INGER entries were indirectly utilized as cross parents or pest resistant donors in various national and provincial rice breeding programs. Based on the incomplete statistics, there were 14.5 million cumulated hectares planting these varieties and hybrids, from which 5.44 MT of increased rough rice has been received by farmers. INGER accelerates the transfer of adapted varieties and hybrids to farmers, and increases the diversity of rice germplasm in cultivation. Therefore, INGER cooperation has made great benefit both in economy and society in China.

Generation of optical vortices using a new design of adaptive helical mirror (AHM) is reported. The new AHM is a reflective device that can generate an optical vortex of any desired topological charge, both positive and negative, within its breakdown limits. The most fascinating feature of the AHM is that the topological charge of the optical vortex generated with it can be changed in real time by varying the excitation voltage. Generation of optical vortices up to topological charge 4 has been demonstrated. The presence of a vortex in the optical field generated with the AHM is confirmed by producing both fork and spiral fringes in an interferometric setup. Various design improvements to further enhance the performance of the reported AHM are discussed. Some of the important applications of AHM are also listed. © 2011 Optical Society of America

There is profound interest in knowing the degree to which China's institutions are capable of protecting its natural forests and biodiversity in the face of economic and political change. China's 2 most important forest-protection policies are its National Forest Protection Program (NFPP) and its national-level nature reserves (NNRs). The NFPP was implemented in 2000 in response to deforestation-caused flooding. We undertook the first national, quantitative assessment of the NFPP and NNRs to examine whether the NFPP achieved its deforestation-reduction target and whether the NNRs deter deforestation altogether. We used MODIS data to estimate forest cover and loss across mainland China (2000-2010). We also assembled the first-ever polygon dataset for China's forested NNRs (n = 237, 74,030 km(2) in 2000) and used both conventional and covariate-matching approaches to compare deforestation rates inside and outside NNRs (2000-2010). In 2000, 1.765 million km(2) or 18.7% of mainland China was forested (12.3% with canopy cover of ≥70%)) or woodland (6.4% with canopy cover <70% and tree plus shrub cover ≥40%). By 2010, 480,203 km(2) of forest and woodland had been lost, an annual deforestation rate of 2.7%. Forest-only loss was 127,473 km(2) (1.05% annually). In the NFPP provinces, the forest-only loss rate was 0.62%, which was 3.3 times lower than in the non-NFPP provinces. Moreover, the Landsat data suggest that these loss rates are overestimates due to large MODIS pixel size. Thus, China appears to have achieved, and even exceeded, its target of reducing deforestation to 1.1% annually in the NFPP provinces. About two-thirds of China's NNRs were effective in protecting forest cover (prevented loss 4073 km(2) unmatched approach; 3148 km(2) matched approach), and within-NNR deforestation rates were higher in provinces with higher overall deforestation. Our results indicate that China's existing institutions can protect domestic forest cover. © 2015 The Authors

The Movement Disorder Society Clinical Diagnostic Criteria for Parkinson's disease (MDS-PD Criteria) was introduced by the Movement Disorder Society in 2015 for research purposes. However, its use for clinical diagnosis of Parkinson disease still needs further revision. This study compares the UK-Criteria versus MDS-PD Criteria in the clinical diagnosis of Parkinson disease referred to the China-Japan Friendship Hospital of Beijing, China. To compare the MDS-PD Criteria with the UK-Criteria and discuss the feasibility of the clinical application of MDS-PD Criteria as a general guide to clinical diagnosis of PD in Chinese PD patients. 150 patients of neurology clinic of China-Japan Friendship Hospital of Beijing were recruited in our research. They were divided into three groups: UK-Criteria group, MDS-PD Criteria group and a combined group of UK and MDS-PD Criteria. Clinical history was collected while physical and auxiliary examinations were done by a trained neurologist according to the corresponding criteria. An interrater reliability analysis using the Kappa statistic claimed substantial agreement (κ = 0.626) between the MDS-PD Criteria and the UK-Criteria. The differences between the diagnostic results of these two criteria were statistically significant by paired Chi-square test (p = 0.000). It was found that levodopa-induced dyskinesia had a good positive predictive value, while early bulbar impairment and inspiratory dysfunction presented a negative predictive value. The MDS-PD Criteria emphasize the importance of non-motor symptoms, keeping the motor symptoms as the core for the clinical diagnosis of PD, and establish categories of diagnosis features and levels of certainty which are more complete and organized to be used and replicated by non specialized physicians to evaluated patients with Parkinsonism. The higher sensitivity of MDS-PD Criteria compared with UK-Criteria is worth being widely used in clinical work.

This paper presents a novel SCM optical transmission system for next-generation WDM-PONs combining broadband optical sources and a Mach-Zehnder interferometric structure. The approach leeds to transport RF signals up to 50 GHz being compatible with RoF systems since a second configuration has been proposed in order to overcome dispersion carrier suppression effect using DSB modulation. The theoretical analysis validates the potentiality of the system also considering the effects of the dispersion slope over the transmission window. (c) 2009 Optical Society of America

Gray, L.A.B.

2004-01-01

In order to fuel China's economic growth, PetroChina began construction of the West to East Natural Gas Pipeline Project (WEPP) in 2001 to transport large quantities of natural gas reserves from the Tarim Basin in the Xinjiang Autonomous Region in far western China to markets in eastern China. The WEPP is the first large diameter, cross-country pipeline project ever constructed in China, and was the first to use automatic welding and automatic ultrasonic inspection on pipelines in China. This paper addressed the management, engineering, procurement and construction challenges of the WEPP. Upon completion of the 3,800 km, 1.016 mm mainline pipeline, construction will begin on other major facilities, such 294 km of lateral line, dual fiber optic conduits with the mainline, 1,100 km of access roads, 23 metering stations, 18 pigging stations, 10 compressor stations, 16 mountain tunnels, 16 aerial crossings, 1 crossing of the Yangtze River, 3 crossings of the Yellow River, a gas control center, and SCADA system. Houston-based Universal Ensco Inc. was awarded a contract to perform a feasibility study as well as a construction supervision contract by PetroChina for the WEPP. Universal also designed a gas turbine drive compressor station at Lunnan and an electric drive compressor station at Zhengzhou. This paper demonstrated that business in China for foreign companies in the pipeline industry is evolving and several changes can be expected as the state planned economy is reformed to a free market economy. 4 refs., 5 tabs., 17 figs.

According to this statement presented to the Committee on Population of the UN Economic and Social Commission for Asia and the Pacific, China is similar to other countries in the region in that its rate of population growth has declined due to government family planning efforts while the absolute size of the population continues to increase because of the widening population base. However, China's enormous population of over 1 billion sets it apart and places great strain on economic development efforts. In the past decade the Chinese government has provided population education for the masses, explaining the relationship between population and socioeconomic development, and its overall family planning program has helped reduce population growth from 24.82/1000 in 1974 to 10.81/1000 in 1984. The net population increase has been over 100 million in the past 10 years, and if the present rate of increase with a total fertility rate of 2.1 is maintained for another 15 years, the total population would exceed 1.3 billion by 2000, posing a grave threat to China's socioeconomic development. The nucleus of China's population policy is its birth policy, whose main points are to promote family planning so that population growth will be in keeping with socioeconomic development and the utilization of natural resources and environmental protection. The policy is in line with the principles and objectives of the World Population Plan of Action adopted in 1974. The government has advocated the practice of "1 couple, 1 child" since 1979 to carry out the population policy and limit the total population to about 1.2 billion by the century's end. 28.17 million couples, 18.25% of the 150 million married couples of childbearing age, had received 1-child certificates by the end of 1984. Generally speaking, most couples in urban areas would be satisfied with 1 child, while those in rural areas usually prefer 2 children. The family planning program is carried out through publicity

Full Text Available China has undergone rapid social transitions within the last few decades. However, mental health issues, challenges to psychological well-being, and poor dietary choices have gradually surfaced. These health concerns are related to the rapid growth of the aging population and of the fast-paced industrialized society. Nevertheless, there is little knowledge about food preferences and psychological well-being measurements in contemporary China. Applying the 2011 China Health and Nutrition Survey (CHNS with a cross-sectional study design (n = 7970, we conducted multinomial logistic regression models to investigate the associations of food preferences, including fast food, salty snacks, fruits, vegetables, and sweetened beverages, with psychological well-being among Chinese middle-aged and older adults (age ≥ 45. Food preferences are mostly associated with psychological well-being (p < 0.05. However, respondents’ preferences regarding fast food, salty snacks, and sweetened beverages are associated not only with poorer psychological health status, but also with positive psychological well-being. We speculate that Chinese older adults may consume Westernized fast food and salty snacks as pleasure to the palate due to the recent Westernization in modern China. We also provide practical implications of results from this preliminary study.

The YES Network is an international association of early-career geoscientists who are primarily under the age of 35 years and are currently engaged in the geosciences in organizations from across the world. The YES Network was formed as a result of the International Year of Planet Earth in 2007. The YES Network aims to establish an interdisciplinary global network of individuals committed to solving these challenges, and furthering the IYPE motto of "Earth Sciences for Society". In 2009, in collaboration with the IYPE and under the patronage of UNESCO, the YES Network organized its first international Congress at the China University of Geosciences in Beijing, China. The Congress focused on climate, environmental and geoscience challenges facing today's society, as well as career and academic pathway challenges faced by early-career geoscientists. More than 300 young geoscientists from across the world attended the conference to present their research and participate in the oral, poster, and roundtable symposia. The roundtable symposia engaged senior and early-career geoscientists via presentations, panel discussions, and working group sessions. These symposia were broadcast as ‘live' webinars to increase international participation. As a result, 41 "virtual" participants from 10 countries and 16 "virtual" speakers from 5 countries were able to participate in these discussions. Since October, the YES Network has continued to expand its membership and develop more projects aligned with the "Earth Sciences for Society" motto. The YES Network is continuing to develop its website and social media networks to increase communication between YES Network members on local, regional and international scales, and it is developing resources to aid early-career geoscientists with opportunities for professional development, international collaboration, and involvement in outreach activities. Members of the YES Network are actively forming connections between the YES Network

Outcome investigation to verify the internal consistency, reproducibility and validity of the adapted Chinese version of the Scoliosis Research Society-22 (SRS-22) questionnaire for measuring health-related quality of life (HRQoL) in children with idiopathic scoliosis. To develop this questionnaire for the outcome measurement in treating Chinese adolescents with idiopathic scoliosis and evaluate its metric qualities. The SRS-22 questionnaire has proven to be a valid instrument for clinical assessment of patients with idiopathic scoliosis and has been successfully translated into Spanish and Turkish. In most developing countries, however, quality of life and psychological health have been poorly described when treating children with idiopathic scoliosis. Trans-cultural adaptation of the SRS-22 questionnaire was carried out according to the International Quality of Life Assessment Project guidelines. The final version was approved by a committee of experts. The questionnaire was completed by 86 adolescents with idiopathic scoliosis who had been treated with a brace; this included 11 males and 75 females, aged from 10 to 18 years (mean 13.9 years). Curve magnitude ranged from 25 degrees to 45 degrees (mean 35.6 degrees ). A subgroup of 30 patients completed the questionnaire again in 3 or 4 weeks. Five common factors were acquired from factorial analysis, and the cumulative contribution ratio was 67.66%. The overall alpha coefficient of the questionnaire was 0.88. Coefficients for individual domains were as follows: function/activity, 0.70; pain, 0.80; self-image, 0.80; mental health, 0.88; and satisfaction, 0.81. The questionnaire as a whole had a test-retest correlation coefficient of 0.97. Test-retest correlation coefficients for individual domains were as follows: function, 0.85; pain, 0.96; self-image, 0.96; mental health, 0.95; and satisfaction, 0.91. The Chinese version of the SRS-22 questionnaire is eligible in terms of reliability and validity, and can be

2010-06-01

The global market for organic food has developed significantly in the past decade. The organic food industry in China is export oriented, with production growing rapidly, although the domestic market remains relatively small. This paper surveys 432 consumers from three cities in China, consequently establishing a logit model to analyse the main factors affecting consumers' choice for organic food. The result indicates that Chinese consumers' intent to purchase organic food is strongly affected by factors such as income, degree of trust in organic food, degree of acceptance of organic food price, and consumers' concern on self-health. This intent is only slightly affected by factors such as consumers' age, education level and concern about environmental protection. Based on the results, the following measures are recommended: reduce the cost of organic food through multiple channels to cut down the market price; establish and perfect the supervision system of organic food; and promote organic food through various channels.

Conjugal intimacy, gender and modernity in contemporary China.

2017-12-15

The new generation of modernity theorists have forecast the democratization of gender relations within intimate relationships in late-modern times. Chinese society has undergone rapid and dramatic changes in its unique trajectory of political, social and economic reform. Using China as an example of a region which has been largely ignored in contemporary social theory, this article enters the debate to contest the extent to which conjugal relationships are democratized in line with modernity. We further test the assertion that modern marriages are characterized by increased self-disclosure and communication between partners. Data from a national survey on Chinese families is analysed in relation to the level of self-disclosure between husbands and wives; gender division of housework; household decision-making; and home ownership. We highlight the impact of gender, cohort and location (urban, rural or migrant) on experiences of modernity and draw attention to the material, social and cultural factors which continue to shape conjugal relations in contemporary Chinese society. Based on our findings, we contest the argument that disclosing intimacy between intimate partners is a defining characteristic of modern relationships, and suggest that other social factors may condition degrees of self-disclosure in marriage. Similarly, we question the extent to which heterosexual conjugal equality is attained: the cultural practices and values of patrilineal family organization, together with material circumstances, continue to influence marital relations in China. © London School of Economics and Political Science 2017.

The worldwide decline of wetland ecosystems calls for an urgent reassessment of their current status from a resilience perspective. Understanding the trajectories of changes that have produced the current situation is fundamental for assessing system resilience. Here, we examine long-term dynamics of wetland ecosystem change by reviewing paleoecological records from 11 representative lakes in China. We identify unprecedented change in alga communities in the context of last two centuries. Striking ecological shifts have occurred in all lakes, yet with spatial and temporal differences. The long-term trajectories of change in diatom species composition and structure indicate gradually eroded system resilience. These ecological shifts were shaped by socio-economic activities as China transformed from a rural agricultural to an industrialized society within the last several decades, during which multiple drivers have accumulated and acted synergistically. The balance between ecosystem and society, which appeared to exist for thousands of years, was broken by increasing population, new technology, and urbanization since the 1980s. The consequences are the emergence of new positive feedbacks with the potential to drive the coupled systems into undesirable states. By linking long-term social and ecological change at a regional scale, our study provides a novel contribution to the understanding of lake ecosystems resilience in present-day China. We argue that sustaining wetland ecosystems requires integrated approaches that incorporate a deeper understanding of social-ecological dynamics over decadal-centennial timescales to address the complex underlying mechanisms leading to the current degradation.

Along the eastcoasts of China are large bodies of water, China has abundant ocean energy resource, such as the theory reserves of tidal resource is about 0.2 billion kW, as early as 1958, Jizhou tidal power station is the first tidal power station in China, which built in Shunde, Guangdong province, and more than 40 small tidal power stations are built in east coastal region in 1960s, and the total installed capacity is about 0.5 MW. But it is a pity, the application and development of tidal energy has not been regarded by the government and ordinary people due to the investment of power plant is big and the technology is not mature, so there are only several small tidal power stations in China, and Jiangxia tidal power station with an installed capacity of 3.2 MW is the most famous. Fortunately, with the rapid development of Chinese economic and society, the renewable and sustainable energy have been regarded by Chinese government, and the application and development of wind energy and solar energy is increasing in an incredible speed, and more and more specialists began to regard the application of tidal energy, and they thought that tidal energy can relieve the energy stress of east coastal region, and many layout of tidal energy exploitation is unfold in recently. This paper discusses the distribution zone and current developmental situation of tidal energy in China. Then, some application practice is described, such as tidal power station and tidal stream turbine. The policies and law of China central government and local governments are described in the following paragraph. At the end, the developmental prospect of tidal energy in future China and the development barriers and recommendations are introduced, respectively. (author)

[Different uses of Fagopyrum esculentum Moench (buckwheat) in Japan and China: what ancient medical documents reveal].

Science.gov (United States)

Tatsumi, Nami; Marui, Eiji

2012-03-01

The purpose of this thesis is to demonstrate that buckwheat has been recognized, both in Japan and China, as a crop that is useful in many ways: as an agricultural crop, and for the healing powers and properties that, according to traditional Chinese medicine, it has. A comparative study of ancient documents pertaining to medicine in these countries has made it clear that this is the case. Buckwheat, however, has been used quite differently in each country. As is shown in some ancient Chinese documents pertaining to medicine, China has treated buckwheat primarily as a medicine for clinical use rather than as an edible crop. Nowadays, buckwheat is eaten only in some regions of China. Although it came to Japan from China as a medicine, in Japan buckwheat gradually became a popular food crop. It has become an important component of traditional Japanese cuisine thanks in part to government support and the strong demand that developed in Japanese society.

Tang Bosin; Wong Siuwai; Lau, Milton Chi-hong

2008-01-01

This study examines the current prospects for and obstacles facing the implementation of social impact assessment (SIA) and participatory planning in the People's Republic of China. During the past two decades, rapid urbanisation and the conversion of rural land for urban development have led to numerous social conflicts and tensions between the Chinese government and its people. SIA and public participation in development decisions have received increasing attention from the Chinese authorities as possible ways to tackle the problem. Based on a Guangzhou case study, this paper argues that the assessment and mitigation of adverse impacts on the community from urban development have been carried out with different objectives, core values and principles when compared with those in Western societies. It concludes that the poor prospects of SIA and collaborative planning in China lie not only in the weak framework for environmental legislation, but also in all institutions concerning state-society relations, the socialist governing ideology and traditional Chinese culture

We developed novel integrated optical packet and circuit switch-node equipment. Compared with our previous equipment, a polarization-independent 4 × 4 semiconductor optical amplifier switch subsystem, gain-controlled optical amplifiers, and one 100 Gbps optical packet transponder and seven 10 Gbps optical path transponders with 10 Gigabit Ethernet (10GbE) client-interfaces were newly installed in the present system. The switch and amplifiers can provide more stable operation without equipment adjustments for the frequent polarization-rotations and dynamic packet-rate changes of optical packets. We constructed an optical packet and circuit integrated ring network testbed consisting of two switch nodes for accelerating network development, and we demonstrated 66 km fiber transmission and switching operation of multiplexed 14-wavelength 10 Gbps optical paths and 100 Gbps optical packets encapsulating 10GbE frames. Error-free (frame error rate optical packets of various packet lengths and packet rates, and stable operation of the network testbed was confirmed. In addition, 4K uncompressed video streaming over OPS links was successfully demonstrated. © 2011 Optical Society of America

The Concept of Harmony in Contemporary P. R. China and in Modern Confucianism

Directory of Open Access Journals (Sweden)

Jana S. ROŠKER

2013-11-01

Full Text Available The present article deals with the idea of the “harmonious society,” which is at the core of contemporary social ideologies in the P. R. China. This concept is examined from three perspectives: the official state interpretations of the concept of harmony (he 和 or hexie 和諧, and the classical and Modern Confucian elucidations. The author concludes that official political interpretations from the P.R. China mainly follow Xunzi’s classical elaboration of this concept, which is in the legalist tradition and implies autocratic elements, whereas the philosophic interpretations written by the Taiwanese Modern Confucians generally elaborate the Mencian, i.e. the more egalitarian and democratic stream of classical Confucian thought.

Rice is one of the main staple foods in East Asia and Southeast Asia, which has occupied more than half of the world's population with 11% of cultivated land. Study on rice can provide direct or indirect information on food security and water source management. Remote sensing has proven to be the most effective method to monitoring the cropland in large scale by using temporary and spectral information. There are two main kinds of satellite have been used to mapping rice including microwave and optical. Rice, as the main crop of paddy fields, the main feature different from other crops is flooding phenomenon at planning stage (Figure 1). Microwave satellites can penetrate through clouds and efficiency on monitoring flooding phenomenon. Meanwhile, the vegetation index based on optical satellite can well distinguish rice from other vegetation. Google Earth Engine is a cloud-based platform that makes it easy to access high-performance computing resources for processing very large geospatial datasets. Google has collected large number of remote sensing satellite data around the world, which providing researchers with the possibility of doing application by using multi-source remote sensing data in a large area. In this work, we map rice planting area in south China through integration of Landsat-8 OLI, Sentienl-2, and Sentinel-1 Synthetic Aperture Radar (SAR) images. The flowchart is shown in figure 2. First, a threshold method the VH polarized backscatter from SAR sensor and vegetation index including normalized difference vegetation index (NDVI) and enhanced vegetation index (EVI) from optical sensor were used the classify the rice extent map. The forest and water surface extent map provided by earth engine were used to mask forest and water. To overcome the problem of the "salt and pepper effect" by Pixel-based classification when the spatial resolution increased, we segment the optical image and use the pixel- based classification results to merge the object

Since the platform "Coursera" is created by the professors of Stanford University Andrew Ng and Daphne Koller, more and more universities have joined in it. From the very beginning, online education is not only about education itself, but also connected with social equality. This is especially significant for the economic transformation in China. In this paper the research and practice on informatization of optical education are described. Online to offline (O2O) education activities, such as online learning and offline meeting, online homework and online to offline discussion, online tests and online to offline evaluation, are combined into our teaching model in the course of Applied Optics. These various O2O strategies were implemented respectively in the autumn-winter small class and the spring-summer middle class according to the constructivism and the idea of open education. We have developed optical education resources such as videos of lectures, light transmission or ray trace animations, online tests, etc. We also divide the learning procedure into 4 steps: First, instead of being given a course offline, students will learn the course online; Second, once a week or two weeks, students will have a discussion in their study groups; Third, students will submit their homework and study reports; Fourth, they will do online and offline tests. The online optical education resources have been shared in some universities in China, together with new challenges to teachers and students when facing the revolution in the e-learning future.

The impact of mental health on labour market outcomes in China.

Mental illnesses account for 20% of the total burden of disease in China. Yet, health policy in China has not devoted much attention to mental health problems and their impact on Chinese society. The objective of this paper is to investigate the impact of mental health status on labour market outcomes, such as employment and income, and provide evidence about some of the economic consequences of mental illnesses. Using the China Health Surveillance Baseline 2001 Survey and an instrumental variables estimation approach, we address possible reverse causation between work and mental health. To estimate the impact of self-reported mental health status, we use the two-part model, the first part estimating a logit equation for the probability of being employed and the second-part estimating an ordinary least squares (OLS) model on the log of individual income condition on being employed. We use a list of symptoms of mental disorders to constitute a measure of mental health status. Our identification strategy relies on instruments that measure average mental health status by zip code other than the observed individual to implement an instrumental variables model. Both men and women suffer a significant reduction in the employment rate and annual income if the average mental health deteriorates at a population level. The mental health index has a positive and significant effect on the likelihood of being employed. Our findings are consistent with what has been found in industrialised countries. This is the first empirical study that reveals that poor mental health status can be disruptive of labour market activities in China. A rapid rise of mental and behavioural problems in population reflects the transition to a market economy and indicates pressing problems that have gone unrecognised and unaddressed. The negative economic consequences in labour market outcomes suggest a potential gain from preventing and curing the mental disorder. Our study about the impact of mental

Static thermo-optic instability in double-pass fiber amplifiers

A coupled-mode formalism, earlier used to describe transverse mode instabilities in single-pass optical fiber amplifiers, is extended to the case of double-pass amplifiers. Contrary to the single-pass case, it is shown that the thermo-optic nonlinearity can couple light at the same frequency...... between the LP01 and LP11 modes, leading to a static deformation of the output beam profile. This novel phenomenon is caused by the interaction of light propagating in either direction with thermo-optic index perturbations caused by light propagating in the opposite direction. The threshold power...... for the static deformation is found to be several times lower than what is typically found for the dynamic modal instabilities observed in single-pass amplifiers.

A nonlinear plasmonic resonator for three-state all-optical switching

KAUST Repository

Amin, Muhammad

2014-01-01

A nonlinear plasmonic resonator design is proposed for three-state all-optical switching at frequencies including near infrared and lower red parts of the spectrum. The tri-stable response required for three-state operation is obtained by enhancing nonlinearities of a Kerr medium through multiple (higher order) plasmons excited on resonator\\'s metallic surfaces. Indeed, simulations demonstrate that exploitation of multiple plasmons equips the proposed resonator with a multi-band tri-stable response, which cannot be obtained using existing nonlinear plasmonic devices that make use of single mode Lorentzian resonances. Multi-band three-state optical switching that can be realized using the proposed resonator has potential applications in optical communications and computing. © 2014 Optical Society of America.

Scaling and contextualizing climate-conflict nexus in historical agrarian China

Science.gov (United States)

Lee, Harry F.

2017-04-01

This study examines climate-conflict nexus in historical agrarian China in multi-scalar and contextualized approach, illustrating what and how socio-political factors could significantly mediate the climate-violent link in pre-industrial society. Previous empirical large-N studies show that violent conflict in historical agrarian society was triggered by climate-induced food scarcity. The relationship was valid in China, Europe, and various geographic regions in the Northern Hemisphere in pre-industrial era. Nevertheless, the observed relationship has only been verified at a macro level (long-term variability of the nexus is emphasized and data over large area are aggregated), and somewhat generalized in nature (only physical environmental factors are controlled). Three inter-related issues remain unresolved: First, the key explanatory variable of violent conflicts may change substantially at different spatio-temporal scales. It is necessary to check whether the climate-conflict nexus is valid at a micro level (about short-term variability of the nexus and data in finer spatial resolution), and explore how the nexus changes along various spatio-temporal dimensions. Second, as the climate-conflict nexus has only been demonstrated in a broad sense, it is necessary to check whether and how the nexus is mediated by local socio-political context. More non-climatic factors pertinent to the cause and distribution of conflicts (e.g., governance, adaptive mechanisms, etc.) should be considered. Third, the methodology applied in the previous studies assumes spatially-independent observations and linear relationship, which may simplify the climate-conflict link. Moreover, the solitary reliance on quantitative methods may neglect those non-quantifiable socio-political dynamics which mediates the climate-conflict nexus. I plan to address the above issues by using disaggregated spatial analysis and in-depth case studies, with close attention to local and temporal differences and

Interannual variation in the fine-mode MODIS aerosol optical depth and its relationship to the changes in sulfur dioxide emissions in China between 2000 and 2010

Directory of Open Access Journals (Sweden)

S. Itahashi

2012-03-01

Full Text Available Anthropogenic SO₂ emissions increased alongside economic development in China at a rate of 12.7% yr⁻¹ from 2000 to 2005. However, under new Chinese government policy, SO₂ emissions declined by 3.9% yr⁻¹ between 2005 and 2009. Between 2000 and 2010, we found that the variability in the fine-mode (submicron aerosol optical depth (AOD over the oceans adjacent to East Asia increased by 3–8% yr⁻¹ to a peak around 2005–2006 and subsequently decreased by 2–7% yr⁻¹, based on observations by the Moderate Resolution Imaging Spectroradiometer (MODIS on board NASA's Terra satellite and simulations by a chemical transport model. This trend is consistent with ground-based observations of aerosol particles at a mountainous background observation site in central Japan. These fluctuations in SO₂ emission intensity and fine-mode AOD are thought to reflect the widespread installation of fuel-gas desulfurization (FGD devices in power plants in China, because aerosol sulfate is a major determinant of the fine-mode AOD in East Asia. Using a chemical transport model, we confirmed that the contribution of particulate sulfate to the fine-mode AOD is more than 70% of the annual mean and that the abovementioned fluctuation in fine-mode AOD is caused mainly by changes in SO₂ emission rather than by other factors such as varying meteorological conditions in East Asia. A strong correlation was also found between satellite-retrieved SO₂ vertical column density and bottom-up SO₂ emissions, both of which were also consistent with observed fine-mode AOD trends. We propose a simplified approach for evaluating changes in SO₂ emissions in China, combining the use of modeled sensitivity coefficients that describe the variation of fine-mode AOD with changes in SO₂ emissions and satellite retrieval. Satellite measurements of fine-mode AOD

The annual averaged values of aerosol optical depth (AOD500) and the Ångström exponent (AE440-870) were measured to be 0.94 ± 0.52 and 1.10 ± 0.21, respectively. The seasonal averaged values of AOD500 (AE440-870) were noticed to be high in summer (autumn) and low in autumn (spring). The characterization of aerosol types showed the dominance of mixed type followed by the biomass burning and urban-industrial type of aerosol at Nanjing. Subsequently, the curvature (a 2) obtained from the second-order polynomial fit and the second derivative of AE (α') were also analyzed to understand the dominant aerosol type. The single scattering albedo at 440 nm (SSA440) varied from 0.88 to 0.93 with relatively lower (higher) values during the summer (spring), suggesting an increase in black carbon and mineral dust (desert dust) aerosols of absorbing (scattering) nature. The averaged monthly and seasonal evolutions of shortwave (0.3-4.0 μm) direct aerosol radiative forcing (DARF) values were computed from the Santa Barbara DISORT Atmospheric Radiative Transfer (SBDART) model both at the top of atmosphere (TOA) and bottom of atmosphere (SUR) during the study period. Further, the aerosol forcing efficiency (AFE) and the corresponding atmospheric heating rates (AHR) were also estimated from the forcing within the atmosphere (ATM). The derived DARF values, therefore, produced a warming effect within the atmosphere due to strong absorption of solar radiation.

We investigate numerically the formation of extreme events or rogue waves in soft glass tellurite fibers and demonstrate that optical loss drastically diminishes shot-to-shot fluctuations characteristic of picosecond pumped supercontinuum (SC). When loss is neglected these fluctuations include...... distributions. Our results thus implicitly show that rogue waves will not occur in any SC spectrum that is limited by loss, such as commercial silica fiber based SC sources. © 2011 Optical Society of America....

In this study, a multi-wavelength polarization lidar was developed at the Lidar Center for Atmosphere Remote Sensing, in Xi'an, China to study the vertical distribution of the optical and microphysical properties of smog aerosols. To better understand smog, two events with different haze conditions observed in January 2015 were analyzed in detail. Using these data, we performed a vertical characterization of smog evolution using the lidar range-squared-corrected signal and the aerosol depolarization ratio. Using inversion with regularization, we retrieved the vertical distribution of aerosol microphysical properties, including volume size distribution, volume concentration, number concentration and effective radius. We also used the Hybrid Single Particle Lagrangian Integrated Trajectory (HYSPLIT) model to analyze aerosol sources during the two episodes. Our results show that the most polluted area in the lower troposphere during smog episodes is located below a height of 1 km above the ground level; under more severe smog conditions, it can be below 0.5 km. In the case of severe smog, we found a large number of spherical and fine particles concentrated in the very low troposphere, even below 0.5 km. Surprisingly, a dust layer with a slight depolarization ratio was observed above the smog layer.

The oriental liver fluke, Clonorchis sinensis, a pathogen causing clonorchiasis, is of major socio-economic importance in East Asia, including China, Korea and Vietnam. This parasite is now recognized as a biocarcinogen strongly linked to cholangiocarcinoma in humans. Here, we describe the status of clonorchiasis in China, where it has been estimated that more than 15 million patients are affected. This paper also summarizes the major advances in the field of clonorchiasis research during last decade, including diagnosis techniques, pathogenesis and genome/transcriptome/proteome studies in the last years. We strongly hope that our work can stimulate the governments of the countries or regions where clonorchiasis is endemic to pay more attention to this disease and establish related guidelines to prevent and control it. © The Author 2015.

China opens the door

Energy Technology Data Exchange (ETDEWEB)

Starke, K.

1997-01-01

The door to China`s vast market for power generation was opened a bit further for foreign firms in November. That is when power ministry head Shi Dazhen said the country would rely on overseas investors for 20 percent of the funding needed to boost output--double the amount foreigners were previously allowed to contribute. Through 1995, foreigners invested $12.2 billion in China`s electricity industry, accounting for 10 percent of total investment. According to Shi, foreign investors will be asked to provide about $17 billion of the $84 billion China plans to invest in the sector over the next five years. Under China`s Ninth Five-Year Plan (1996-2000), the government aims to boost the country`s power generation capacity at the rate of 15,000 MW to 20,000 MW annually by the year 2000. Since China`s public external debt balance already exceeds $80 billion, however, the government would seem to have little choice but to allow foreigners a greater role. Shi also said that foreigners would be allowed 100 percent ownership of PRC power projects. This is discouraged under China`s current industry guidelines. It is, however, expected to be permitted under China`s first build-operate-transfer (BOT) law, which was anticipated by the end of 1996, says Susan Urkevich, director of project finance at HSBC Investment Bank Asia in Hong Kong. Indeed, China`s first BOT is already happening.

Height-resolved data of the particle optical properties, the vertical extend of the haze layer, aerosol stratification, and the diurnal cycle of vertical mixing over the Pearl River Delta in southern China are presented. The observations were performed with Raman lidar and Sun photometer at Xinken (22.6°N, 113.6°E) near the south coast of China throughout October 2004. The lidar run almost full time on 21 days. Sun photometer data were taken on 23 days, from about 0800 to 1700 local time. The particle optical depth (at about 533-nm wavelength) ranged from 0.3-1.7 and was, on average, 0.92. Ångström exponents varied from 0.65-1.35 (for wavelengths 380 to 502 nm) and from 0.75-1.6 (for 502 to 1044 nm), mean values were 0.97 and 1.22. The haze-layer mean extinction-to-backscatter ratio ranged from 35-59 sr, and was, on average, 46.7 sr. The top of the haze layer reached to heights of 1.5-3 km in most cases.

Comparative Time Series Analysis of Aerosol Optical Depth over Sites in United States and China Using ARIMA Modeling

Science.gov (United States)

Li, X.; Zhang, C.; Li, W.

2017-12-01

Long-term spatiotemporal analysis and modeling of aerosol optical depth (AOD) distribution is of paramount importance to study radiative forcing, climate change, and human health. This study is focused on the trends and variations of AOD over six stations located in United States and China during 2003 to 2015, using satellite-retrieved Moderate Resolution Imaging Spectrometer (MODIS) Collection 6 retrievals and ground measurements derived from Aerosol Robotic NETwork (AERONET). An autoregressive integrated moving average (ARIMA) model is applied to simulate and predict AOD values. The R2, adjusted R2, Root Mean Square Error (RMSE), Mean Absolute Error (MAE), Mean Absolute Percentage Error (MAPE), and Bayesian Information Criterion (BIC) are used as indices to select the best fitted model. Results show that there is a persistent decreasing trend in AOD for both MODIS data and AERONET data over three stations. Monthly and seasonal AOD variations reveal consistent aerosol patterns over stations along mid-latitudes. Regional differences impacted by climatology and land cover types are observed for the selected stations. Statistical validation of time series models indicates that the non-seasonal ARIMA model performs better for AERONET AOD data than for MODIS AOD data over most stations, suggesting the method works better for data with higher quality. By contrast, the seasonal ARIMA model reproduces the seasonal variations of MODIS AOD data much more precisely. Overall, the reasonably predicted results indicate the applicability and feasibility of the stochastic ARIMA modeling technique to forecast future and missing AOD values.

2011-04-11

A linearized dual parallel Mach-Zehnder modulator (DPMZM) based on electro-optic (EO) polymer was both fabricated, and experimentally used to suppress the third-order intermodulation distortion (IMD3) in a coherent analog fiber optic link. This optical transmitter design was based on a new EO chromophore called B10, which was synthesized for applications dealing with the fiber-optic communication systems. The chromophore was mixed with amorphous polycarbonate (APC) to form the waveguide's core material. The DPMZM was configured with two MZMs, of different lengths in parallel, with unbalanced input and output couplers and a phase shifter in one arm. In this configuration each of the MZMs carried a different optical power, and imposed a different depth of optical modulation. When the two optical beams from the MZMs were combined to generate the transmitted signal it was possible to set the IMD3 produced by each modulator to be equal in amplitude but 180° out of phase from the other. Therefore, the resulting IMD3 of the DPMZM transmitter was effectively canceled out during two-tone experiments. A reduction of the IMD3 below the noise floor was observed while leaving fifth-order distortion (IMD5) as the dominant IMD product. This configuration has the capability of broadband operation and shot-noise limited operation simultaneously. © 2011 Optical Society of America

The solar observing facilities in China are introduced with the emphasis on the development in recent years and future plans for both ground and space-based solar instrumentations. The recent solar instruments are as follows: A new generation Chinese Spectral Radioreliograph (CSRH) has been constructed at Mingantu Observing Station in Zhengxiangbaiqi, inner Mongolia of China since 2013 and is in test observations now. CSRH has two arrays with 40 × 4.5 m and 60 × 2 m parabolic antennas covering 0.4-2 GHz and 2-15 GHz frequency range. CSRH is renamed as MUSER (Mingantu Ultrawide Spectral Radiheliograph) after its accomplishment. A new 1 m vacuum solar telescope (NVST) has been installed in 2010 at Fuxian lake, 60 km away from Kunming, Yunana. At present it is the best seeing place in China. A new telescope called ONSET (Optical and NIR Solar Eruption Tracer) has been established at the same site as NVST in 2011. ONSET has been put into operation since 2013. For future ground-based plans, Chinese Giant Solar Telescope (CGST) with spatial resolution equivalent to 8m and effective area of 5m full-aperture telescope has been proposed and was formally listed into the National Plans of Major Science & Technology Infrastructures in China. The pre-study and site survey for CGST have been pursued. A 1-meter mid-infrared telescope for precise measurement of the solar magnetic field has been funded by NSFC in 2014 as a national major scientific instrument development project. This project will develop the first mid-infrared solar magnetic observation instrument in the world aiming at increasing the precision of the transverse magnetic field measurement by one order of magnitude. For future ground-based plans, we promote the Deep-space Solar Observatory (DSO) with 1-m aperture telescope to be formally funded. The ASO-S (an Advanced Space-based Solar Observatory) has been supported in background phase by Space Science Program as a small mission. Other related space solar

Agent-Based Approach for Modelling the Labour Migration from China to Russia

Valeriy Leonidovich Makarov

2017-06-01

Full Text Available The article describes the process of labour migration from China to Russia and shows its modelling using the agent-based approach. This approach allows us to simulate an artificial society in a computer program taking into account the diversity of individuals under consideration, as well as to model a set of laws and rules of conduct that make up the institutional environment in which the members of this society live. A brief review and analysis of agent-based migration models presented in the foreign literature are given. The agent-based model of labour migration from China to Russia developed by the Central Economic Mathematical Institute of the Russian Academy of Sciences simulates human behaviour close to reality, which is based on their internal purposes, determining the agents choice of territory as a place of residence. Therefore, at the development of the agents of the model and their behaviour algorithms, as well as the organization of the environment in which they exist and interact, the main characteristics of the population of two neighbouring countries and their demographic processes have been considered. Using the model, two experiments have been conducted. The purpose of the first of them was to assess the effect of depreciation of the rubble against the yuan on the overall indexes of labour migration, as well as its structure. In the second experiment, the procedure of the search of the information by agents for the migratory decision-making was changing. Namely, all generalizing information on the average salary by types of activity and skill level of employees, both in China and Russia, became available to all agents irrespective of their qualification level.

Impacts of climate change and inter-annual variability on cereal crops in China from 1980 to 2008.

Science.gov (United States)

Zhang, Tianyi; Huang, Yao

2012-06-01

Negative climate impacts on crop yield increase pressures on food security in China. In this study, climatic impacts on cereal yields (rice, wheat and maize) were investigated by analyzing climate-yield relationships from 1980 to 2008. Results indicated that warming was significant, but trends in precipitation and solar radiation were not statistically significant in most of China. In general, maize is particularly sensitive to warming. However, increase in temperature was correlated with both lower and higher yield of rice and wheat, which is inconsistent with the current view that warming results in decline in yields. Of the three cereal crops, further analysis suggested that reduction in yields with higher temperature is accompanied by lower precipitation, which mainly occurred in northern parts of China, suggesting droughts reduced yield due to lack of water resources. Similarly, a positive correlation between temperature and yield can be alternatively explained by the effect of solar radiation, mainly in the southern part of China where water resources are abundant. Overall, our study suggests that it is inter-annual variations in precipitation and solar radiation that have driven change in cereal yields in China over the last three decades.

Scenario analysis and path selection of low-carbon transformation in China based on a modified IPAT model.

Directory of Open Access Journals (Sweden)

Liang Chen

Full Text Available This paper presents a forecast and analysis of population, economic development, energy consumption and CO2 emissions variation in China in the short- and long-term steps before 2020 with 2007 as the base year. The widely applied IPAT model, which is the basis for calculations, projections, and scenarios of greenhouse gases (GHGs reformulated as the Kaya equation, is extended to analyze and predict the relations between human activities and the environment. Four scenarios of CO2 emissions are used including business as usual (BAU, energy efficiency improvement scenario (EEI, low carbon scenario (LC and enhanced low carbon scenario (ELC. The results show that carbon intensity will be reduced by 40-45% as scheduled and economic growth rate will be 6% in China under LC scenario by 2020. The LC scenario, as the most appropriate and the most feasible scheme for China's low-carbon development in the future, can maximize the harmonious development of economy, society, energy and environmental systems. Assuming China's development follows the LC scenario, the paper further gives four paths of low-carbon transformation in China: technological innovation, industrial structure optimization, energy structure optimization and policy guidance.

Atoms, molecules, and light have been at the forefront of understanding quantum mechanics, since its discovery over 100 years ago. Since then the field has progressed from understanding the most fundamental aspects of how particles behave under quantum mechanics to controlling individual atoms for creating new technologies. While matter and light are from ordinary experience rather different, with today's control of coherent quantum phenomena many of the ideas freely cross their respective boundaries. Some of the topics that will be covered at the conference include, but are not limited to, cold atoms and cold molecules, ultrafast and precision spectroscopy, quantum manipulation and precision measurement, quantum computing and quantum communication, and quantum metrology. In this conference we aim to bring together the leading experts working in the frontiers of atomic, molecular, and optical systems.

Full Text Available The future of the Iranian political relations with other countries  especially China in the post-nuclear-agreementera is of serious  importance in the Iranian foreign policy in the Rouhani  administration. Despite turbulences in the relations of the two  countries in recent years, theirs have been stronger than the trade  relations between Iran and western countries. For this reason, the  shift from ordinary to strategic relations between Iran and China is  attracting serious attention in the political circles in Iran. The  supporters argue for the present and future stance of China in the  international society and its constructive role during the western- imposed sanctions against Iran. The opponents refer to the poorer  Chinese technology as opposed to their Western rivals and to  ambivalent and at time anti-Iranian stances Beijing adopted in the  Iranian nuclear problem. The question this paper seeks to answer is  whether there is a possibility of the promotion of the relations of the  two countries in future and the possible obstacles in the way.

Optical Imaging of Ionizing Radiation from Clinical Sources.

Shaffer, Travis M; Drain, Charles Michael; Grimm, Jan

2016-11-01

Nuclear medicine uses ionizing radiation for both in vivo diagnosis and therapy. Ionizing radiation comes from a variety of sources, including x-rays, beam therapy, brachytherapy, and various injected radionuclides. Although PET and SPECT remain clinical mainstays, optical readouts of ionizing radiation offer numerous benefits and complement these standard techniques. Furthermore, for ionizing radiation sources that cannot be imaged using these standard techniques, optical imaging offers a unique imaging alternative. This article reviews optical imaging of both radionuclide- and beam-based ionizing radiation from high-energy photons and charged particles through mechanisms including radioluminescence, Cerenkov luminescence, and scintillation. Therapeutically, these visible photons have been combined with photodynamic therapeutic agents preclinically for increasing therapeutic response at depths difficult to reach with external light sources. Last, new microscopy methods that allow single-cell optical imaging of radionuclides are reviewed. © 2016 by the Society of Nuclear Medicine and Molecular Imaging, Inc.

Korea-China Joint R and D on Doppler Lidar Technology

International Nuclear Information System (INIS)

Cha, Hyung Ki; Kim, D. H.; Kwon, S. O.; Yang, K. H.; Song, I. K.

2009-03-01

Doppler lidar technology is to monitor atmospheric wind velocity by measuring the light scattering signals between a laser and aerosol particles or molecules existing in the atmosphere. When the particles (or molecules) in the atmosphere are moving by wind force, the frequency of backscattering light is shifted by doppler effect, so that the wind velocity profile can be obtained by measurement of the shifted frequencies. When the laser radiation is scanned in four different direction, three dimensional wind profiles are obtained. The Anhui Institute of Optics and Fine Mechanics under the China Academy of Sciences has developed and operated the doppler lidar system for long time. In this project we want to developed a new technologies adopted to the chinese doppler system and to test the updated In the process of collaboration between China and Korea research teams, we want to learn the state-of-art technology involved in the doppler lidar system

Feasibility of infrared Earth tracking for deep-space optical communications.

Chen, Yijiang; Hemmati, Hamid; Ortiz, Gerry G

2012-01-01

Infrared (IR) Earth thermal tracking is a viable option for optical communications to distant planet and outer-planetary missions. However, blurring due to finite receiver aperture size distorts IR Earth images in the presence of Earth's nonuniform thermal emission and limits its applicability. We demonstrate a deconvolution algorithm that can overcome this limitation and reduce the error from blurring to a negligible level.

Arditty, Hervé

1982-01-01

Currently there is considerable interest in the application of optical meth­ ods for the measurement of absolute rotation. Active approaches, so-called ring laser gyros, have been under serious development for at least 15 years. More recently, passive approaches using ring resonators or multi turn fiber interferometers have also demonstrated much pro~ise. The only previous conference devoted exclusively to optical rotation sensors, held in 1978 in San Diego, California, was organized by the Society of Photo-optical Instru­ mentation Engineers(S.P.I.E.J. Although the main emphasis at that conference was on ring laser gyros, a number of papers were also included that described the early development of fiber gyroscopes. Since then the field of fiber optic rotation sensors has grown so rapidly that a conference devoted primarily to this subject was needed. The First International Conference on Fiber-Optic Rotation Sensors was held at the Massachusetts Institute of Technology, Cambridge, Massachusetts, Nove~­ b...

GHG (Increasing greenhouse gas) emissions in China imposes enormous pressure on China's government and society. The increasing GHG trend is primarily driven by the fast expansion of high energy-intensive sectors including the chemical industry. This study investigates energy consumption and CO 2 emissions in the processes of chemical production in China through calculating the amounts of CO 2 emissions and estimating the reduction potential in the near future. The research is based on a two-level perspective which treats the entire industry as Level one and six key sub-sectors as Level two, including coal-based ammonia, calcium carbide, caustic soda, coal-based methanol, sodium carbonate, and yellow phosphorus. These two levels are used in order to address the complexity caused by the fact that there are more than 40 thousand chemical products in this industry and the performance levels of the technologies employed are extremely uneven. Three scenarios with different technological improvements are defined to estimate the emissions of the six sub-sectors and analyze the implied reduction potential in the near future. The results highlight the pivotal role that regulation and policy administration could play in controlling the CO 2 emissions by promoting average technology performances in this industry.

Applied optics course in Zhejiang University is a National Excellent Resource Sharing Course in China, and the online to offline teaching strategies have been implemented and shared with dozens of universities and colleges in China. Discussion is an important activity in teaching. In this paper our main consideration is designing the discussion questions and group works so as to develop the students' critical thinking, cooperative and sharing spirits, and communication abilities in the cosmopolitan era. Typical questions that connect different chapters and help the students to understand the relationship between each sub-system in both field of view and aperture are given for discussion. We inspire the students to complete group works such as ray trace programming by cooperation and then make presentations. All of these create a circumstance for sharing thoughts and developing intelligence and knowledge. A poll shows that the students pay more attention to optical design than before and have made progress in conversation and cooperation.

Full Text Available This article briefly discusses various definitions and concepts of the so-called information society. The term information society has been proposed to refer to the post-industrial society in which information plays a pivotal role. The definitions that have been proposed over the years highlight five underlying characterisations of an information society: technological, economic, sociological, spatial, and cultural. This article discusses those characteristics. While the emergence of an information society may be just a figment of one’s imagination, the concept could be a good organising principle to describe and analyse the changes of the past 50 years and of the future in the 21st century.

The following aspects are discussed: the public health problems of acute poisoning in China in recent years; the characteristics of acute poisoning; the negative effects of poison cases on the society and economy. The four stages of development of a poison control system in China are: (1) clinical hospital as the only facility used for detoxification; (2) institutes and hospitals of occupational medicine got involved in the program; (3) the traditional model of poison control changed to the modern National Poison Control Center (NPCC), and its network got established and it began to play a key role; (4) establishment of a multi-disciplinary network for dealing with emergencies in which chemical poison control is an important component. Introduction of the operations of the NPCC: the functions of the center are a 24 h hotline service, clinical consultants service, poison identification and diagnosis, laboratory analysis, education for public, training for physicians, coordination of anti-dotes, and the development of a network of poison control centers for dealing with chemical emergencies. The work practice and achievement of NPCC and its network in the field of poison control during the last 3 years is discussed. Lessons from SARS infection: to extend the network, to strengthen multi-disciplinary cooperation, enhance communication between centers, to pay attention to capacity building, to improve reporting systems, and to share resources

Review and challenges of policies of environmental protection and sustainable development in China.

China is confronted with the dual task of developing its national economy and protecting its ecological environment. Since the 1980s, China's policies on environmental protection and sustainable development have experienced five changes: (1) progression from the adoption of environmental protection as a basic state policy to the adoption of sustainable development strategy; (2) changing focus from pollution control to ecological conservation equally; (3) shifting from end-of-pipe treatment to source control; (4) moving from point source treatment to regional environmental governance; and (5) a turn away from administrative management-based approaches and towards a legal means and economic instruments-based approach. Since 1992, China has set down sustainable development as a basic national strategy. However, environmental pollution and ecological degradation in China have continued to be serious problems and have inflicted great damage on the economy and quality of life. The beginning of the 21st century is a critical juncture for China's efforts towards sustaining rapid economic development, intensifying environmental protection efforts, and curbing ecological degradation. As the largest developing country, China's policies on environmental protection and sustainable development will be of primary importance not only for China, but also the world. Realizing a completely well-off society by the year 2020 is seen as a crucial task by the Chinese government and an important goal for China's economic development in the new century, however, attaining it would require a four-fold increase over China's year 2000 GDP. Therefore, speeding up economic development is a major mission during the next two decades and doing so will bring great challenges in controlling depletion of natural resources and environmental pollution. By taking a critical look at the development of Chinese environmental policy, we try to determine how best to coordinate the relationship between the

Despite of extensive efforts into characterization of the sources in severe haze pollution periods in the megacity of Shanghai, the study of aerosol composition, mass-size distribution and optical properties to PM1 in the pollution periods remain poorly understood. Here we conducted a 47days real-time measurement of submicron aerosol (PM1) composition and size distribution by a High-Resolution Time-of-Flight Aerosol Mass spectrometer (HR-TOF-AMS), particle light scattering by a Cavity Attenuated Phase Shift ALBedo monitor (CAPS-ALB) and Photoacoustic Extinctionmeter (PAX) in Shanghai, China, from November 28, 2016 to January 12, 2017. The average PM1 concentration was 85.9(±14.7) μg/m3 during the pollution period, which was nearly 4 times higher than that of clean period. Increased scattering coefficient during EP was associated with higher secondary inorganic aerosols and organics. We also observed organics mass size distribution for different pollution extents showing different distribution characteristics. There were no obvious differences for ammonium nitrate and ammonium sulfate among the pollution periods, which represented single peak distributions, and peaks ranged at 650-700nm and 700nm, respectively. A strong relationship can be expected between PM1 compounds mass concentration size distribution and scattering coefficient, suggesting that chemical composition, size distribution of the particles and their variations could also contribute to the extinction coefficients. Organics and secondary inorganic species to particle light scattering were quantified. The results showed that organics and ammonium nitrate were the largest contribution to scattering coefficients of PM1. The contribution of (NH4)2SO4 to the light scattering exceeded that of NH4NO3 during clean period due to the enhanced sulfate concentrations. Our results elucidate substantial changes of aerosol composition, formation mechanisms, size distribution and optical properties due to local

The Evolution of Environmental Policy in the People’s Republic of China

Richard Louis Edmonds

2011-01-01

Full Text Available This paper outlines how the evolution of China’s policy and study of the environment are reflected in the scholarly literature, paying special attention to the impact of the country’s environmental developments on international relations. In particular, it examines accounts of how China has moved from an isolated national scientific and environmental control infrastructure into the centre of international environmental debates as its society has opened and the geographical scale of ecological problems has expanded. The paper also identifies the continuing inhibitors to China’s ability to control environmental degradation – including lack of transparency, elite manipulation, and bureaucratic weaknesses – despite the opening of China’s system to limited participation of civil society in its environmental debates.

Trichloroethylene (TCE) is a carcinogen that has been linked to kidney cancer and possibly other cancer sites including non-Hodgkin lymphoma. Its use in China has increased since the early 1990s with China's growing metal, electronic, and telecommunications industries. We examined historical occupational TCE air concentration patterns in a database of TCE inspection measurements collected in Shanghai, China to identify temporal trends and broad contrasts among occupations and industries. Using a database of 932 short-term, area TCE air inspection measurements collected in Shanghai worksites from 1968 through 2000 (median year 1986), we developed mixed-effects models to evaluate job-, industry-, and time-specific TCE air concentrations. Models of TCE air concentrations from Shanghai work sites predicted that exposures decreased 5-10% per year between 1968 and 2000. Measurements collected near launderers and dry cleaners had the highest predicted geometric means (GM for 1986 = 150-190 mg m(-3)). The majority (53%) of the measurements were collected in metal treatment jobs. In a model restricted to measurements in metal treatment jobs, predicted GMs for 1986 varied 35-fold across industries, from 11 mg m(-3) in 'other metal products/repair' industries to 390 mg m(-3) in 'ships/aircrafts' industries. TCE workplace air concentrations appeared to have dropped over time in Shanghai, China between 1968 and 2000. Understanding differences in TCE concentrations across time, occupations, and industries may assist future epidemiologic studies in China.

This paper presents the Time Shared Optical Network (TSON) as metro mesh network architecture for guaranteed, statistically-multiplexed services. TSON proposes a flexible and tunable time-wavelength assignment along with one-way tree-based reservation and node architecture. It delivers guaranteed sub-wavelength and multi-granular network services without wavelength conversion, time-slice interchange and optical buffering. Simulation results demonstrate high network utilization, fast service delivery, and low end-to-end delay on a contention-free sub-wavelength optical transport network. In addition, implementation complexity in terms of Layer 2 aggregation, grooming and optical switching has been evaluated. © 2011 Optical Society of America

At present, the diagnosis-related groups-based prospective payment system (DRG-PPS) that has been implemented in China is merely a prototype called the simplified DRG-PPS, which is known as the 'ceiling price for a single disease'. Given that studies on the effects of a simplified DRG-PPS in China have usually been controversial, we aim to synthesize evidence examining whether DRGs can reduce medical costs and length of stay (LOS) in China. Data were searched from both Chinese [Wan Fang and China National Knowledge Infrastructure Database (CNKI)] and international databases (Web of Science and PubMed), as well as the official websites of Chinese health departments in the 2004-2016 period. Only studies with a design that included both experimental (with DRG-PPS implementation) and control groups (without DRG-PPS implementation) were included in the review. The studies were based on inpatient samples from public hospitals distributed in 12 provinces of mainland China. Among them, 80.95% (17/21) revealed that hospitalization costs could be reduced significantly, and 50.00% (8/16) indicated that length of stay could be decreased significantly. In addition, the government reports showed the enormous differences in pricing standards and LOS in various provinces, even for the same disease. We conclude that the simplified DRGs are useful in controlling hospitalization costs, but they fail to reduce LOS. Much work remains to be done in China to improve the simplified DRG-PPS. © The Author 2017. Published by Oxford University Press on behalf of Royal Society of Tropical Medicine and Hygiene.

Optical wireless communication in data centers

In the last decade data centers have become a crucial element in modern human society. However, to keep pace with internet data rate growth, new technologies supporting data center should develop. Integration of optical wireless communication (OWC) in data centers is one of the proposed technologies as augmented technology to the fiber network. One implementation of the OWC technology is deployment of optical wireless transceiver on top of the existing cable/fiber network as extension to the top of rack (TOR) switch; in this way, a dynamic and flexible network is created. Optical wireless communication could reduce energy consumption, increase the data rate, reduce the communication latency, increase flexibility and scalability, and reduce maintenance time and cost, in comparison to extra fiber network deployment. In this paper we review up to date literature in the field, propose an implementation scheme of OWC network, discuss ways to reduce energy consumption by parallel link communication and report preliminary measurement result of university data center environment.

Retrieval of High-Resolution Atmospheric Particulate Matter Concentrations from Satellite-Based Aerosol Optical Thickness over the Pearl River Delta Area, China

2015-06-01

Full Text Available Satellite remote sensing offers an effective approach to estimate indicators of air quality on a large scale. It is critically significant for air quality monitoring in areas experiencing rapid urbanization and consequently severe air pollution, like the Pearl River Delta (PRD in China. This paper starts with examining ground observations of particulate matter (PM and the relationship between PM10 (particles smaller than 10 μm and aerosol optical thickness (AOT by analyzing observations on the sampling sites in the PRD. A linear regression (R2 = 0.51 is carried out using MODIS-derived 500 m-resolution AOT and PM10 concentration from monitoring stations. Data of atmospheric boundary layer (ABL height and relative humidity are used to make vertical and humidity corrections on AOT. Results after correction show higher correlations (R2 = 0.55 between extinction coefficient and PM10. However, coarse spatial resolution of meteorological data affects the smoothness of retrieved maps, which suggests high-resolution and accurate meteorological data are critical to increase retrieval accuracy of PM. Finally, the model provides the spatial distribution maps of instantaneous and yearly average PM10 over the PRD. It is proved that observed PM10 is more relevant to yearly mean AOT than instantaneous values.

Fertility preference being related to government policy in China, women generally understate their desired family size when questioned directly. A binomial probit model is, therefore, presented to estimate the probability that family-size preferences in Shifang County, Sichuan, China, are understated. The model provides estimates on the percentage of respondent understatement along with the number of children, women of different ages and social characteristics truly desire. Women's preferences for sons versus daughters are also examined. The study found that women desire on average 1/2 more children than that which they state. Understating was in greatest evidence among urban, educated, and younger women more sensitive to the government's 1-child policy. Preference for sons was found to be weaker than expected, yet strong nonetheless in rural areas among women desiring only 1 child. Sons are considered to cause more worry for parents in China due to an aggressive, risk-taking nature. Possible explanations for the decline of son preference include increasing familial costs for sons' betrothment and marriage, changing household structures, and increasing status of and job opportunities for women in Chinese society. In closing, the paper highlights that couples restrict marital fertility out of interest for national prosperity and the welfare of future generations, not personal preference for small families. Were government policy to relax, fertility would rise to preferred levels.

The society has an active chapter at Kolkata. The society was formed with the main aim to promote, encourage and develop the growth of Vacuum Science, Techniques and Applications in India. In order to achieve this aim it has conducted a number of short term courses at graduate and technician levels on vacuum science and technology on topics ranging from low vacuum to ultrahigh vacuum So far it has conducted 39 such courses at different parts of the country and imparted training to more than 1200 persons in the field. Some of these courses were in-plant training courses conducted on the premises of the establishment and designed to take care of the special needs of the establishment. IVS also regularly conducts national and international seminars and symposia on vacuum science and technology with special emphasis on some theme related to applications of vacuum. A large number of delegates from all over India take part in the deliberations of such seminars and symposia and present their work. IVS also arranges technical visits to different industries and research institutes. The society also helped in the UNESCO sponsored post-graduate level courses in vacuum science, technology and applications conducted by Mumbai University. The society has also designed a certificate and diploma course for graduate level students studying vacuum science and technology and has submitted a syllabus to the academic council of the University of Mumbai for their approval, we hope that some colleges affiliated to the university will start this course from the coming academic year. IVS extended its support in standardizing many of the vacuum instruments and played a vital role in helping to set up a Regional Testing Centre along with BARC. As part of the development of vacuum education, the society arranges the participation of

The Protestant medical missions to China: the introduction of Western medicine with vaccination.

Fu, Louis

Modern medicine in China began with the arrival of Anglo-American Protestant missionaries in the early 19th century. Conditions were vastly different from the times of the Jesuits in Peking during the 17th and 18th centuries, when the priests enjoyed the endorsement of the Court and high officials. Faced with hostile and xenophobic officialdom and populace, surgeons of the British East India Company in collaboration with missionaries took the initiative. In 1805 Dr Alexander Pearson (1780-1874) introduced smallpox vaccination in Macao and Canton. Reverend Dr Robert Morrison (1782-1834) of the London Missionary Society with another East India Company Surgeon, Dr John Livingstone (1829) opened a dispensary for the poor in Macao in 1820. These pioneers paved the way for later Anglo-American medical missionaries who revolutionized medical practice in China.

2010-01-01

This paper has compared the legal frameworks supporting water management in Europe and China, with special focus on integrated river basin management (IRBM) to identify synergies and opportunities in policymaking and implementation. The research shows that China has committed to the efficient management of water resources through various policy tools during the current period. This commitment, however, has often been interrupted and distorted by politics, resulting in the neglect of socioeconomic and environmental priorities. The European legal framework supporting water management underwent a complex and lengthy development, but with the adoption of the Water Framework Directive provides a policy model on which to develop an integrated and sustainable approach to river basin management, elements of which may help to meet the demands of the emerging 21st century Chinese society on these critical natural resources.

Scrub typhus is a vector-borne disease, which has recently reemerged in China. In this study, we describe the distribution and incidence of scrub typhus cases in China from 2006 to 2014 and quantify differences in scrub typhus cases with respect to sex, age, and occupation. The results of our study indicate that the annual incidence of scrub typhus has increased during the study period. The number of cases peaked in 2014, which was 12.8 times greater than the number of cases reported in 2006. Most (77.97%) of the cases were reported in five provinces (Guangdong, Yunnan, Anhui, Fujian, and Shandong). Our study also demonstrates that the incidence rate of scrub typhus was significantly higher in females compared to males (P scrub typhus incidence, but also document an expansion in the geographic distribution throughout the country. © The American Society of Tropical Medicine and Hygiene.

Novel reassortants of H7N9, H10N8, and H5N6 avian influenza viruses (AIVs) are currently circulating in China's poultry flocks, occasionally infecting humans and other mammals. Combined with the sometimes enzootic H5N1 and H9N2 strains, this cauldron of genetically diverse AIVs pose significant risks to public health. Here, we review the epidemiology, evolution, and recent outbreaks of AIVs in China, discuss reasons behind the recent increase in the emergence of novel AIVs, and identify warning signs which may point to the emergence of a potentially virulent and highly transmissible AIV to humans. This review will be useful to authorities who consider options for the detection and control of AIV transmission in animals and humans, with the goal of preventing future epidemics and pandemics.

Cognitive capital is an emerging paradigm that captures the criticality of investing in children whilst neural proliferation and development of brain architecture are at their peak. Distinct from financial capital, cognitive capital represents investment in future human potential from interventions in nutrition, health, education, child protection, and social welfare systems that optimize brain development. The return on investment is significant given the plasticity of the developing brain in response to positive stimuli. Investment in brain development results in improved health and well-being, educational outcomes, skills, employment, and quality of life. The inverse is also true. Negative stimuli lead to depreciating cognitive capital, poorer mental and physical health and educational outcomes, and decreased life chances. Cognitive capital could be an organizing framework for China's next phase of development to ensure the building of a prosperous society. Through significant commitment from the government, China has seen remarkable improvements in under-five mortality, literacy rates, access to basic education, life expectancy, and gross domestic product in the past few decades as the result of an expansion of publicly funded social services. Yet, inequities remain within and across communities and regions. In 2015, China had a country ranking of 97 for gross national income per capita, highlighting remaining challenges across the whole population. Cognitive capital relies on a package of forward-looking policies that lead to equitable, efficient, and effective use of existing and future resources. This is consistent with the United Nations Convention on the Rights of the Child. Investments in interventions that maximize optimal brain development in children, realize children's rights, and contribute to future economic growth, defined as "cognitive capital," represent a significant opportunity for improving children's lives, nation-building, and future

Measuring the Dynamic Efficiency of Regional Industrial Green Transformation in China

2018-02-01

Full Text Available The green concept has become one of the key demands of the current era of development in China. As an attempt to cope with climate change and constraints of resources and environment, the industrial green transformation is bound to have a dramatic impact on the whole society. This paper enriches the understanding of industrial green transformation by highlighting its social attributes. Combining a hybrid model with a window analysis, this paper measures the dynamic efficiency of regional industrial green transformation in China from 2006 to 2015. In general, Beijing, Tianjin, Shanghai, Jiangsu, Zhejiang, Fujian, Shandong and Guangdong obtain the best performance; industrial water use has the lowest and most unstable efficiency among various resources. Tobit regression model, thereafter, is used to analyze the impact of hypothetical factors on the efficiency of industrial green transformation. The findings demonstrate that reduction and lean management of state-owned property, promoting the development of the productive service industry, minimizing the proportion of fossil energy use and establishing an excellent economic basis can have nationally positive impacts on the regional industrial green transformation; the progress of the productive service industry is the key to industrial green transformation in Eastern China, while the internal optimization of the industrial sector should be paid more attention in other regions, especially in Western China. Finally, detailed discussions and policy suggestions at a regional level as well as research prospects are given.
