Rural-urban land conversion is positively effective as far as social and economic benefits are concerned (Yang, 2002), but its negative effect is also evident, resulting in such problems as low efficiency of rural land configuration and loss of social welfare. Consequently, farm-ers should also have an equal chance to enjoy the social welfare enhanced by land conversion. Based on the theories of welfare economy, this paper puts forward policy suggestions by discussing the welfare changes of various interest groups, builds the model of welfare distribution, and analyzes the conditions of maximizing social welfare. The absolute and opposite value of social welfare is closely related with the speed of rural-urban land conversion, and governments should give farmers and collectives fair compensa-tion to make up for the utility loss caused by land expropriation, which are conclusions drawn from this paper. This study aims to provide a theoretical basis for regulating targets and evaluation criteria, realizing the mechanism and implementation of public po-lices during rural-urban land conversion.展开更多

This conclusion holds true after removal of sample selection bias and policy expectation factor.Further analysis reveals that Labor Contract Law's welfare improvement effect was more significant for migrant workers in regions where workers had poor bargaining power. Other economic factors during the same period of time did not affect the law's labor protection effect. Our findings give a clear answer to controversies over whether the Labor Contract Law can improve labor rights for underprivileged groups, and are of reference value for developing labor protection systems.展开更多

For many years, mechanical castration and surgical castration have been practiced to sterilize the animals. However, these castration methods are not humane because of the associated risk of death, pain, and stress. Recently, immunocastration targeting the hypothalamic-pituitary-gonadal axis(HPG) axis has been reported as an animal-friendly approach that circumvents many of the concerns with conventional castration, and suggested by researches as an alternative to surgical castration. However, there is no compilation of updated information on the use of immunocastration in sheep and goats. Therefore, this review aims to summarize the developmental process from traditional surgical castration to immunocastration and to screen the process of immune targets. It also compares the respective advantages and disadvantages of traditional castration technologies and immunocastration, in particular including analyses in the characteristics, features application and welfare benefits of immunocastration in sheep and goats were also analyzed.展开更多

A choice experiment approach is used to elicit Chinese consumer preferences for various food safety attributes using data from a 2008 urban consumer survey. An alternative welfare calculation is used to model aggregate market impacts of select food safety measures. Our results show that the largest welfare gains are found in the current government-run certiifcation program. The implementation of a third-party certiifcation system, a traceability network and a product label would generate signiifcant value and would help reduce current system inefifciencies in China. This study builds on previous research and provides an alternative approach for calculating consumer valuation of safety and quality attributes that can be used to estimate aggregate economic and welfare impacts.展开更多

Dry-bulb temperature, relative humidity, dew point, shaded area, air velocity, and maximum temperature were measured beneath each shed. The temperature-humidity index （THI） and the shading efficiency were calculated for each cowshed. The trials were conducted using 180 lactating Holstein Friesian cows; twenty cows housed beneath each shade structure. Measurements performed on cows were respiration rate, skin temperature, and rectal temperature; moreover, the milk produced by each cow was recorded, and the feed intake. High air velocities were recorded under high shade structures which enhance the aeration; consequently, maximum temperatures, and THI recorded beneath high sheds were less than those recorded beneath low sheds; also, skin temperatures, and respiration rates for cows housed under high sheds were less than those measured for animals housed under low sheds（differences were found to be significant）. Thereby, increasing shed height enhances dairy cows＇ microclimate under Egyptian conditions （hot climate）; consequently, the milk production increases. The best orientation is the east-west orientation, which is preferable for hot climates. The exploitation of cooling has significant effect on microclimate, cooling enhances the ambient environment and provides comfortable zone for dairy cows within which cows reach high production levels.展开更多

文摘In recent years,carbon emissions have gradually evolved from an environment issue into a political and economic one.Carbon tariff has brought about new trade barriers of developed countries,and in order to enhance the industrial competitiveness of developed countries,it will produce unfavorable impact on developing countries.Concentrated on the manufacturing industry,which is the most intensive high-carbon industry in China's export structure,this article studies the relationship between carbon tariff policy and industry structure of export trade and builds up a relation between climate change and international trade.First,by means of establishing a partial equilibrium model,it applies geometric analysis and mathematical analysis to compute the impact on China's manufacturing export trade and the consequences of the introduction of the US carbon tariff to China's manufacturing industry that has already imposed a domestic shipping carbon tax.Furthermore,with the application of the GTAP model,it estimates the overall economic and welfare effects on China's manufacturing industry if the US and Europe introduce carbon tariff by means of four ways,and then analyzes the influence on China's manufacturing industry export structure and social welfare as well.The result shows that the introduction of the US carbon import tariff lowers China's export price and export volume,and the implementation of a domestic carbon tax justifies a higher export price and a lower export volume for China.However,the degree of export reduction is smaller than that under the effect of the US carbon tariff.In the case of developed countries imposing carbon tariff on China's energy-intensive industries,such as chemical rubber products,oil and coal-processing industry and paper industry,whose export would be reduced,the negative impact on the paper industry is the severest,which will decrease the paper industry's export ranging from 1.79%to 6.05%,whereas the other industries' export will increase.Anyhow,it will promote China's manufacturing industry to adjust the export structure to a certain extent.In addition,it will lead to a decrease in China's welfare,with a decrease between $2,134 billion and $8,347 billion.Finally,this paper provides information on international coordination,export structure adjustment and green manufacturing adjustment as a reference for the development of China's manufacturing industry.

文摘Rural-urban land conversion is a universal phenomenon in the rapid process of economic development and urban growth.The welfare of farmers who lost their farmland attracted a widespread concern within the society and academia.However,further research about differentiated policies according to the characteristics of different farmer groups is still need to be conducted.This article divides the land-lost farmers into three age groups:younger than 45,45-65,and more than 65.It proposes a welfare index system including eight functional areas based on different age groups of affected farmers,taking four districts of Wuhan City as case study area.Fuzzy mathematics method is used to derive the aggregated welfare effect index.Our analysis show that the overall welfare levels of land-lost farmers of all age groups declined,but with a varying degree,with the level of welfare in those farmers who are 45-65 years old,younger than 45 years old,and older than 65 years old decreased by 18.7%,16.6%,and 12.7%,respectively.The direction and degree of effects on the functional activity index varies among different groups.Economic conditions,living environment,health,and social participation of all age groups decrease while social security and housing conditions increase.On the other hand,development opportunities,social communication,and leisure have different changing directions in different age stages.These results call for differentiated and tailor-made compensation policies for land-lost farmers,towards improving the welfare levels of all farmers and reduce the disparity among them.
文摘This paper employs difference-in-differences(DID) approach to evaluate the effects of China's Labor Contract Law's implementation on rural migrant workers' welfare.Our findings suggest that the Labor Contract Law has reduced rural migrant workers' working hours by 23%, and increased their social insurance coverage by 10% to 26%. This conclusion holds true after removal of sample selection bias and policy expectation factor.Further analysis reveals that Labor Contract Law's welfare improvement effect was more significant for migrant workers in regions where workers had poor bargaining power. Other economic factors during the same period of time did not affect the law's labor protection effect. Our findings give a clear answer to controversies over whether the Labor Contract Law can improve labor rights for underprivileged groups, and are of reference value for developing labor protection systems.

文摘Castration of male animals is a common practice in the meat industry aimed at reducing aggressive behavior, preventing unpleasant flavor, and controlling undesirable breeding. For many years, mechanical castration and surgical castration have been practiced to sterilize the animals. However, these castration methods are not humane because of the associated risk of death, pain, and stress. Recently, immunocastration targeting the hypothalamic-pituitary-gonadal axis(HPG) axis has been reported as an animal-friendly approach that circumvents many of the concerns with conventional castration, and suggested by researches as an alternative to surgical castration. However, there is no compilation of updated information on the use of immunocastration in sheep and goats. Therefore, this review aims to summarize the developmental process from traditional surgical castration to immunocastration and to screen the process of immune targets. It also compares the respective advantages and disadvantages of traditional castration technologies and immunocastration, in particular including analyses in the characteristics, features application and welfare benefits of immunocastration in sheep and goats were also analyzed.

文摘This study provides an economics assessment of various food safety measures in China. A choice experiment approach is used to elicit Chinese consumer preferences for various food safety attributes using data from a 2008 urban consumer survey. An alternative welfare calculation is used to model aggregate market impacts of select food safety measures. Our results show that the largest welfare gains are found in the current government-run certiifcation program. The implementation of a third-party certiifcation system, a traceability network and a product label would generate signiifcant value and would help reduce current system inefifciencies in China. This study builds on previous research and provides an alternative approach for calculating consumer valuation of safety and quality attributes that can be used to estimate aggregate economic and welfare impacts.
文摘Nine cowsheds were used, the differences between each cowshed are orientation （east-west or north-south）, cooling （with or without）, and height （3 m, 5 m or 8 m height）. Dry-bulb temperature, relative humidity, dew point, shaded area, air velocity, and maximum temperature were measured beneath each shed. The temperature-humidity index （THI） and the shading efficiency were calculated for each cowshed. The trials were conducted using 180 lactating Holstein Friesian cows; twenty cows housed beneath each shade structure. Measurements performed on cows were respiration rate, skin temperature, and rectal temperature; moreover, the milk produced by each cow was recorded, and the feed intake. High air velocities were recorded under high shade structures which enhance the aeration; consequently, maximum temperatures, and THI recorded beneath high sheds were less than those recorded beneath low sheds; also, skin temperatures, and respiration rates for cows housed under high sheds were less than those measured for animals housed under low sheds（differences were found to be significant）. Thereby, increasing shed height enhances dairy cows＇ microclimate under Egyptian conditions （hot climate）; consequently, the milk production increases. The best orientation is the east-west orientation, which is preferable for hot climates. The exploitation of cooling has significant effect on microclimate, cooling enhances the ambient environment and provides comfortable zone for dairy cows within which cows reach high production levels.

文摘Regional coordinated ecological development is a new form of regional coordinated development that aims to construct an ecological civilization in the“new normal”period.The coordinated ecological development of the Beijing-Tianjin-Hebei(BTH)region is especially significant because this region is leading the overall coordinated development and reform in China.Based on complex system theory,synergetics,and the ecological civilization and green development ideas of the“new normal”period,we constructed a regional ecological synergy measurement model that scientifically evaluates the dynamic evolution of the BTH ecological synergy level from 2006 to 2018.Using an econometric model,we also analyzed the welfare effect and the regional heterogeneity of ecological synergy in regional development.First,it was found that in general,the degree of ecological synergy in BTH increased yearly up to 2018 with a strong development trend.The speed of ecological synergy in the Tianjin-Hebei and Beijing-Hebei subsystems was accelerating during that period,but the development potential of the ecological synergy in Beijing-Tianjin was insufficient and slow-growing.Second,whereas Beijing had entered the stage of moderate coordinated ecological development,Tianjin and Hebei remained in the low level of coordinated development;moreover,the coordinated development was unstable.The uneven development of the internal subsystems in BTH restricted the development of the cooperative effect and the overall development of the region.Third,improving the degree of ecological synergy significantly benefited the social and economic welfare in BTH.Finally,the welfare effect of the degree of ecological synergy showed a significant regional heterogeneity,being significantly higher in Tianjin and Hebei than in Beijing.This result indicates that improving the ecological synergy can narrow the development gaps between Tianjin,Hebei,and Beijing.To further improve the level of regional ecological synergy,we should innovate the coordinated model of regional development,implement the collaborative ecological development model,generate new growth drivers for the green development of BTH based on a reasonable division of labor,difference positioning,and active integration,create a soft environment for an innovation ecosystem that promotes regional ecological synergy,and build a regional innovation ecosystem led by Beijing and Xiongan.Next,we should establish a balanced regional-interest mechanism with ecological environmental protection that supports regional green and high-quality development.
文摘We emphasize the importance of studying the primate brain in cognitive neuroscience and suggest a new mind-set in primate experimentation within the boundaries of animal welfare regulations.Specifically,we list the advantages of investigating both genes and neural mechanisms and processes in the emergence of behavioral and cognitive functions,and propose the establishment of an open field of primate research.The latter may be conducted by implementing and harmonizing experimental practices with ethical guidelines that regulate(1)management of natural parks with free-moving populations of target nonhuman primates,(2)establishment of indoor-outdoor labs for both system genetics and neuroscience investigations,and(3)hotel space and technologies which remotely collect and dislocate information regarding primates geographically located elsewhere.
文摘Background:Biochemical and hematological parameters are important tools for assessing the physiological profile of vital organs,and can be recorded to create reference values used for clinical diagnosis of diseases.Many research laboratories lack the means to establish their own set of reference parameters for use in their research,and while there are articles in the literature that discuss laboratory parameters for healthy BALB/c mice,few studies address the evaluation of these parameters in pathological situations,such as in mice inoculated with Ehrlich tumor.Method:BALB/c-FMABC mice previously inoculated with Ehrlich tumor were maintained under appropriate conditions.Blood samples were taken for analysis of hematological parameters using automated and semi-automated equipment to create a set of the animal welfare parameters for evaluation.Result:Results were obtained for all the hematological parameters for all groups analyzed.These showed:statistically significant differences between the initial and final tumor weight;comparable initial tumour volume and weight;an increase in leukocytes in the 7-day group with a characteristic predominance of lymphocytes and neutrophils;statistically significant changes in RDW in the 21-day group and in the welfare parameters in the 28-day group.Conclusion:The study successfully defined and established reference values for hematological and welfare parameters for all groups analyzed.

文摘Stocking density is an important factor for animal production performance.It appears particularly urgent and important to research systematically on stocking density for the dual restriction of environmental protection and animal welfare.This review dealt with the influence of stocking density on ducks'productivity and health through production performance,animal behavior and animal welfare,and analyzed the possible mechanism of high stocking density reducing production performance,resulting in abnormal behavior and stress,causing welfare and health problems.We consider that it might be associated with heat stress,more spatial competition(to gather the food,drinking water,sports area,etc.),as well as the quality deterioration of litter and house air caused by high stocking density.Finally,we put forward some suggestions on the study of stocking density's effects on ducks,and proposed the future work that need to be studied and problems that need to be solved imminently.
