Qiuxia MENG, Jianjie ZHANG, Wenyan XIE, Huaiping ZHOU, Qiang ZHANG

《农业科学与工程前沿(英文)》 2020年 第7卷 第4期   页码 440-454 doi: 10.15302/J-FASE-2020353

摘要:

Africa has experienced increasing aridity and higher frequency of droughts due to climate change during the half past century with possible adverse effects on agricultural production, especially in dry areas with low rainfall. Under the auspices of the Africa Water Action Program between the Chinese Ministry of Science and Technology (MOST) and the United Nations Environment Program (UNEP), the Institute of Agricultural Environment and Resources, Shanxi Academy of Agricultural Sciences (SAAS-IAER) has worked closely with domestic and overseas partners on technology transfer in Morocco, Zambia, Egypt, Niger and Ethiopia from 2008 to 2013. A drought early warning system has been established and validated, and drought adaptation technologies have been trialed, modified, demonstrated and extended in African countries, and this shows great potential to increase crop production, water and fertilizer use efficiency and desert control in rainfed areas of Africa. The project has continued for six years and is a successful case of technology transfer and capacity building in Africa. The knowledge and experience gained will be useful to researchers, technicians, aid agencies and policy makers who work on agricultural technology transfer for in dry areas of Africa.

SUSTAINABLE PLANT PEST MANAGEMENT THROUGH OPTIMIZATION AND MINIMIZATION

Plant Production and Protection Division (NSP), Food and Agriculture Organization of the United Nations

《农业科学与工程前沿(英文)》 2022年 第9卷 第1期   页码 161-166 doi: 10.15302/J-FASE-2021426

摘要:

Plant pests and diseases have significant negative impacts on global food security, world trade and rural livelihoods. Climate change exacerbates these impacts in certain parts of the world. Overreliance on pesticides as the primary tool for plant pest management leads to problems such as pesticide resistance and pest resurgence. Environmental and food safety concerns are also associated with overuse of pesticides in crop production. There is clearly a need for a shift in pest management strategies and practices globally. Optimization of structures and functions in crop production agroecosystems through soil conservation practices and cropping diversification can improve pest regulation services provided in the systems. Prioritization of safer alternatives and practices in the IPM pyramid, such as resistant varieties and biopesticides, helps minimize the use of potentially risky agricultural inputs such as synthetic pesticides. Investment is needed to boost the development of innovative green technologies and practices. Production, distribution, use and regulatory capacities need to be strengthened to facilitate large-scale adoption of green technologies and practices. Finally, policy, financial and market instruments should be wielded to provide an enabling environment for the transformation to sustainable plant pest and disease management strategies and practices worldwide.

 

全球2℃温升目标与应对气候变化长期目标的演进

高云, 高翔, 张晓华

《工程(英文)》 2017年 第3卷 第2期   页码 272-278 doi: 10.1016/J.ENG.2017.01.022

摘要:

《巴黎协定》提出把全球平均地表气温升幅控制在较工业化前水平的2°C 之内,并努力限制在1.5°C之内。这是第一个使“全球2°C 温升目标”具备法律效力的国际条约,《联合国气候变化框架公约》第二条关于最终目标的定性表述,至此演进为《巴黎协定》第二条包含具体数值的全球温升目标。从政府间气候变化专门委员会(IPCC) 第二次评估开始,为《联合国气候变化框架公约》谈判提供有助于确定定量化长期目标的科学信息就成为后续历次评估的重要任务,但由于涉及非科学评估范畴的价值判断,IPCC 从未从科学上认定全球升温到何种程度是不可接受的。应对气候变化长期目标的确定经历了长期的过程,“全球2°C 温升目标”是建立在科学评估基础上的一个政治共识。本文从“全球2°C 温升目标”的由来、IPCC 围绕《联合国气候变化框架公约》第二条开展的系列评估,以及不同政治层面对温升目标的推动等几个方面,分析了国际应对气候变化长期目标的演进过程,及其对未来科学评估、谈判进程和全球低碳发展走向的影响。

Haloacetic acids in swimming pool and spa water in the United States and China

Xiaomao WANG,Garcia Leal M I,Xiaolu ZHANG,Hongwei YANG,Yuefeng XIE

《环境科学与工程前沿(英文)》 2014年 第8卷 第6期   页码 820-824 doi: 10.1007/s11783-014-0712-7

摘要: The objective of this study is to investigate the occurrence of haloacetic acids (HAAs), a group of disinfection byproducts, in swimming pool and spa water. The samples were collected from six indoor pools, six outdoor pools and three spas in Pennsylvania, the United States, and from five outdoor pools and nine indoor pools in Beijing, China. Five HAAs (HAA5), including monochloroacetic acid, dichloroacetic acid, trichloroacetic acid, monobromoacetic acid, and dibromoacetic acid were analyzed. Total chlorine, pH and total organic carbon concentration were analyzed as well. Results indicated that the levels of HAA5 in swimming pools and spas in the United States ranged from 70 to 3980 μg·L , with an arithmetic average at 1440 μg·L and a median level at 1150 μg·L . These levels are much higher than the levels reported in chlorinated drinking water and are likely due to organic matters released from swimmers’ bodies. The levels of HAA5 in swimming pools in China ranged from 13 to 332 μg·L , with an arithmetic average at 117 μg·L and a median level at 114 μg·L . The lower HAA levels in swimming pools in China were due to the lower chlorine residuals. Results from this study can help water professionals to better understand the formation and stability of HAAs in chlorinated water and assess risks associated with exposures to HAAs in swimming pools and spas.

Evolving perspectives on biofuels in the United States

Lisa C. DIRKS, Gary W. DIRKS, Jianguo WU

《能源前沿(英文)》 2012年 第6卷 第4期   页码 379-393 doi: 10.1007/s11708-012-0213-y

摘要: Biofuels represent an important source of renewable energy and may play a crucial role in developing sustainable energy strategies for many countries and the world as a whole. The pros and cons of biofuels, however, have been debated both scientifically and politically. They remain a topic of controversy. In this paper, the evolvement of the perspectives and policies on biofuels in the United States in the past several decades was reviewed. Four different periods, that is, the period prior to 1978 (marked by the passage of the Energy Act in 1978); 1978–1989 (ending with the passage of the Clean Air Act Amendments of 1990); 1990–2004 (ending with the passage of the energy act of 2005); and 2005 to the present, which were characterized by defining events of major policy importance were identified. Each time period was assessed using the Ostrom institutional analysis and development (IAD) framework to show the impact of the evolving interests and influences of global players on policy choices related to biofuels in the United States. The US has a long history of supporting corn-based ethanol and more recently advanced biofuels. Changes in perspectives on biofuels from largely unrelated groups led to changes in policy and market dynamics. Until the late 1990s, most perspectives and policies tended to be aligned and significantly supportive of corn-based ethanol in the United States. In the early 2000s, it became clear that the complications associated with first generation biofuels and corn-based ethanol in particular, were too numerous and too severe to overlook. The need for better options has spurred interest in new technologies and more environmentally benign feedstocks, but, there is little prospect for biofuels playing a significant role in the near term without greater alignment among key players.

Sustainable Program Quality Management of International Infrastructure Construction

Steve Hsueh-Ming Wang

《工程管理前沿(英文)》 2016年 第3卷 第3期   页码 239-245 doi: 10.15302/J-FEM-2016047

摘要: Management of the program quality for international infrastructure construction projects is complicated. Sustainability of these programs is the key for them to succeed in their lifecycles. This paper investigated current program quality management and compared it with the results of recent surveys of KGMP. A method for the sustainable program quality management of the international infrastructure construction management is proposed and demonstrated by research projects. The cycle of accountability, predictability, balance ability, and policy was proposed. The findings from the KGMP’s survey and this research show that the trend of the sustainable program quality management of the international infrastructure construction is transferring from agility to alacrity in the balancing of the metrics among economy, ecology, culture, and politics.

Achievements of the national malaria control and elimination program in the People’s Republic of China

《医学前沿(英文)》 2023年 第17卷 第1期   页码 85-92 doi: 10.1007/s11684-021-0917-7

摘要: In 2017, China achieved the target of zero indigenous malaria case for the first time, and has been certified as malaria free by World Health Organization in 2021. To further summarize the historical achievements and technical experiences of the elimination program, a project on the Roadmap Analysis and Verification for Malaria Elimination in China was carried out. Results of the project were compiled and published as the Atlas of Malaria Transmission in China (The Atlas). The Atlas using modern digital information technologies, has been supported by various data from 24 malaria endemic provinces of China since 1950, to assess the changes in malaria epidemic patterns from 1950 to 2019 at national and provincial levels. The Atlas is designed as two volumes, including a total of 1850 thematic maps and more than 130 charts, consisting of introductory maps, thematic maps of malaria epidemic and control at national and provincial levels. It objectively and directly shows the epidemic history, evolution process, and great achievements of the national malaria control and elimination program in China. The Atlas has important reference value for summing up historical experience in the national malaria elimination program of China, and malaria control and elimination in other endemic countries in the world.

Risk evaluation for the task transfer of an aircraft maintenance program based on a multielement connection

《工程管理前沿(英文)》 doi: 10.1007/s42524-023-0282-0

摘要: This paper proposes a framework for evaluating the efficacy and suitability of maintenance programs with a focus on quantitative risk assessment in the domain of aircraft maintenance task transfer. The analysis is anchored in the principles of Maintenance Steering Group-3 (MSG-3) logic decision paradigms. The paper advances a holistic risk assessment index architecture tailored for the task transfer of maintenance programs. Utilizing the analytic network process (ANP), the study quantifies the weight interrelationships among diverse variables, incorporating expert-elicited subjective weighting. A multielement connection number-based evaluative model is employed to characterize decision-specific data, thereby facilitating the quantification of task transfer-associated risk through the appraisal of set-pair potentials. Moreover, the paper conducts a temporal risk trend analysis founded on partial connection numbers of varying orders. This analytical construct serves to streamline the process of risk assessment pertinent to maintenance program task transfer. The empirical component of this research, exemplified through a case study of the Boeing 737NG aircraft maintenance program, corroborates the methodological robustness and pragmatic applicability of the proposed framework in the quantification and analysis of mission transfer risk.

Status of hyperhomocysteinemia in China: results from the China Stroke High-risk Population Screening Program

《医学前沿(英文)》 2021年 第15卷 第6期   页码 903-912 doi: 10.1007/s11684-021-0871-4

摘要: A nationwide survey was conducted from October 2018 to September 2019 to assess the prevalence of hyperhomocysteinemia (Hhcy) and its influencing factors in China. A standardized questionnaire was used to collect information. Hhcy was defined as the level of serum homocysteine (HCY) 15.0 µmol/L. The H-type hypertension (HHYP) was defined as hypertension with an elevated serum HCY (15.0 µmol/L). Finally, 110 551 residents 40 years of age from 31 provinces in the mainland of China were included. Overall, the median serum HCY level was 10.9 µmol/L (interquartile range 7.9–15.1). A total of 28 633 participants (25.9%) were defined as Hhcy. The Hhcy prevalence ranged from 7.9% in Shanghai to 56.8% in Tianjin. The data showed that serum HCY levels were associated with age, male gender, cigarette smoking, hypertension, diabetes, ethnicity, endurance in exercise (inverse), and fruit and vegetable intake (inverse). In addition, 15 486 participants were defined as HHYP, and the rate was 14.0%. HHYP was an independent predictor of stroke with an adjusted odds ratio of 1.752 (95% CI 1.338–2.105). The geographical distribution pattern of the Hhcy epidemic reflects dynamic differences, and national strategies should be carried out to further improve the care of patients with Hhcy across China.

Cultural differences define diagnosis and genomic medicine practice: implications for undiagnosed diseases program

摘要:

Despite the current acceleration and increasing leadership of Chinese genetics research, genetics and its clinical application have largely been imported to China from the Occident. Neither genetics nor the scientific reductionism underpinning its clinical application is integral to the traditional Chinese worldview. Given that disease concepts and their incumbent diagnoses are historically derived and culturally meaningful, we hypothesize that the cultural expectations of genetic diagnoses and medical genetics practice differ between the Occident and China. Specifically, we suggest that an undiagnosed diseases program in China will differ from the recently established Undiagnosed Diseases Program at the United States National Institutes of Health; a culturally sensitive concept will integrate traditional Chinese understanding of disease with the scientific reductionism of Occidental medicine.
