Farmers' cultural quality,technical level and ideological and moral standards,directly determine the success of countryside construction and agricultural development. Therefore,many countries have attached great importance to farmers' education and training,and established the training mode with their own characteristics,playing an important role in improving the comprehensive quality of farmers,promoting the advance of social modernization,and propelling sustainable social development. By probing into the history of the development of foreign farmers' education and training,I summarize the main features,and conduct in-depth scientific analysis,which will provide a reference for developing farmers' education and training,and resolving issues concerning agriculture,countryside and farmers in China during the period of social transformation.展开更多

The analysis indicated that there are differences in employment opportunity,employment sector,employment ability,wage income and employment stability between land-expropriated farmers. Besides,though skill training,it is feasible to effectively improve employment quality of land-expropriated farmers. The skill training exerts a significant effect on employment and urban adaptation of land-expropriated farmers. The mode of skill training promoting employment quality was proposed. Skill training can raise human resource level of land-expropriated farmers,and increase their labor and employment skills,to help them realize regular employment and smoothly become citizens. For fund sources for skill training,government and land expropriation unit should bring into play active role. And skill training should be undertaken under the guidance of government and support of land expropriation unit.展开更多

Farm level data were collected from 2,900 farmers over 11,000 farm plots. The difference-in-difference estimator is employed to test the impact of this intervention on crop yields and incomes. Farmers were randomly put into two distinct groups: the treatment (early training) and control (late training). After the collection of baseline data, the treatment group received crop husbandry training and a starter pack which included inputs and cash both worth about US$230. The control group received the intervention after a year. The main findings of this study are that the intervention does not have any significant impact on crop yields and crop incomes. However the authors do find some evidences that as a result of the intervention, the value of chemicals used by farmers decreased by about GH^25 The study concludes by noting that although some changes do occur over the period, and it is not possible to attribute these changes to the MiDA training programme for all the indicators of interest except chemical costs.展开更多

Nevertheless, excessive nitrogen fertilizer use in China has resulted in severe environmental problems. The goal of this paper is to examine the impacts of an improved nitrogen management (INM) training experiment on farmers' chemical nitrogen (N) use behaviors in maize production in China. Based on household data collected from 813 maize farmers in Shandong, China, this study finds that while INM training can significantly reduce farmers' N fertilizer use, an INM training is not sufficient to change farmer's practices significantly, and farmers only partially adopted the recommended INM. This study reveals that China faces challenges to transform its agriculture to a low-carbon one. The research also sheds light on China's extension system and future technologies in meeting the objectives of reducing the excessive nitrogen fertilizer use in agricultural production.展开更多

Firstly, the antenna patterns modeling of the phased array system is exploited to build the radar sweeping model and the signal propagation model. Secondly, the relationship between the variation of the radiated power and the antenna beam pointing angles in the given airspace is analyzed. Based on the above two points, the sample with obvious amplitude characteristics of the pulse amplitude train can be screened out after detecting the train peaks. Finally, the sample is matched to the subsequent pulse amplitude train based on the Hausdorff distance. The proposed methods have less prior knowledge and higher efficiency and are easier to process. By cross correlating the sample of the pulse amplitude train with the sample data of the antenna follow-up radiation, the probability of detection of the beam pointing direction becomes larger in case that the subsequent antenna beam returns to the specific position.展开更多

To improve the capability of train self control, a combined speed measurement and positioning method based on speed sensor and radar which is assisted by global positioning system(GPS) is proposed to improve the accuracy of measurement and reduce the dependence on the ground equipment. In consideration of the fact that the filtering precision of Kalman filter will decrease when the statistical characteristics are changing, this paper uses fuzzy comprehensive evaluation method to evaluate the sub filter, and information distribution coefficients are dynamically adjusted according to filtering reliability, which can improve the fusion accuracy and fault tolerance of the system. The sub filter is required to carry on the covariance shaping adaptive filtering when it is in the suboptimal state. The adjustment factor of error covariance is obtained according to the minimized cost function, which can improve the matching degree between the measured residual variance and the system recursive residual. The simulation results show that the improved filter algorithm can track the changes of the system effectively, enhance the filtering accuracy significantly, and improve the measurement accuracies of train speed and distance.展开更多

The search was conducted using the key words "high-intensity intermittent training" or "high-intensity interval exercise" or "interval running" or "sprint interval training" and "endurance runners" or "long distance runners". A systematic approach was used to evaluate the 783 articles identified for initial review. Studies were included if they investigated HIIT in recreational endurance runners. The methodological quality of the studies was evaluated using the Physiotherapy Evidence Database(PEDro) scale(for intervention studies) and the modified Downs and Black Quality Index(for cross-sectional studies).Results: Twenty-three studies met the inclusionary criteria for review. The results are presented in 2 parts: cross-sectional(n = 15) and intervention studies(n = 8). In the 15 cross-sectional studies selected, endurance runners performed at least 1 HIIT protocol, and the acute impact on physiological, neuromuscular, metabolic and/or biomechanical variables was assessed. Intervention studies lasted a minimum of 4 weeks, with 10 weeks being the longest intervention period, and included 2 to 4 HIIT sessions per week. Most of these studies combined HIIT sessions with continuous run(CR) sessions; 2 studies' subjects performed HIIT exclusively.Conclusion: HIIT-based running plans(2 to 3 HIIT sessions per week, combining HIIT and CR runs) show athletic performance improvements in endurance runners by improving maximal oxygen uptake and running economy along with muscular and metabolic adaptations. To maximize the adaptations to training, both HIIT and CR must be part of training programs for endurance runners.展开更多

文摘Under the direction of theory of human resources development,this thesis analyzes the impact of rural human resources development oncultivating new-type farmers.Firstly,it increases the input of rural basic education;secondly,it reinforces the vocational education and technologytraining;thirdly,it promotes the rural medical and public health services;fourthly,it quickens the rural labor transfer.The status quo of China's ruralhuman resources has been analyzed as follows:in terms of the quantity of rural human resources,the status quo is large and quick-developed baseof rural human resources,high labor participatory rate,and constitution of low age;in terms of the quality of rural human resources,the status quois the ubiquitous low quality of rural human resources,low technological level of rural human resources,and overall low physical quality of farmers;in terms of the structure of rural human resources,the status quo is the irrational industrial structure distribution and imbalanced regional structuredistribution.The thesis also discusses the edification of theory of human resources development in cultivating new-type farmers.First,in terms ofthe control over quantity of rural human resources,it is to keep the stability of family planning policy,and expedite the transfer of rural surplus la-bor;second,in terms of promoting the quality of rural human resources,it is to bolster the development of reserve rural labor force resources,toconstruct the adult educational training system with Chinese characteristics,and to build rural primary health care system;third,in terms of adjus-ting the structure of rural human resources,it is to perfect rural human resources market,and adjust rural economical structure and talents struc-ture.

文摘Objective: This systematic review aimed to critically analyze the literature to determine how high-intensity intermittent training(HIIT) affects recreational endurance runners in the short-and long-term.Methods: Electronic databases were searched for literature dating from January 2000 to October 2015. The search was conducted using the key words "high-intensity intermittent training" or "high-intensity interval exercise" or "interval running" or "sprint interval training" and "endurance runners" or "long distance runners". A systematic approach was used to evaluate the 783 articles identified for initial review. Studies were included if they investigated HIIT in recreational endurance runners. The methodological quality of the studies was evaluated using the Physiotherapy Evidence Database(PEDro) scale(for intervention studies) and the modified Downs and Black Quality Index(for cross-sectional studies).Results: Twenty-three studies met the inclusionary criteria for review. The results are presented in 2 parts: cross-sectional(n = 15) and intervention studies(n = 8). In the 15 cross-sectional studies selected, endurance runners performed at least 1 HIIT protocol, and the acute impact on physiological, neuromuscular, metabolic and/or biomechanical variables was assessed. Intervention studies lasted a minimum of 4 weeks, with 10 weeks being the longest intervention period, and included 2 to 4 HIIT sessions per week. Most of these studies combined HIIT sessions with continuous run(CR) sessions; 2 studies' subjects performed HIIT exclusively.Conclusion: HIIT-based running plans(2 to 3 HIIT sessions per week, combining HIIT and CR runs) show athletic performance improvements in endurance runners by improving maximal oxygen uptake and running economy along with muscular and metabolic adaptations. To maximize the adaptations to training, both HIIT and CR must be part of training programs for endurance runners.
