The Particularity of the Development of Labor Relationship in the 70-Year History of the People’s Republic of China

The past seven decades witnesses a stage marked by"ossification-consolidation-emptiness"as regards domestic labor relationship.It is highly probable that China is to be inaugurated by the stage of"falsification"in forthcoming days.A major cause is rooted in that labor relationship is the output of economic development that would request that labor relationship chime with it.The development course of labor relationship since the founding of PRC explicitly evinces that"flexibility"might be incurred in case labor relationship fails to align with economic development and with demands of marketing competitiveness.It might even propel main bodies of labor relationship to circumvent labor laws,as is verified by prevalence of large-scaled labor dispatching,and of"labor dispatching under the disguise of outsourcing".Lawmakers thus need to further ruminate over degree of tolerance on labor legislation.

Parental myopia, near work, hours of sleep and myopia in Chinese children

Background/Aims: Juvenile myopia is a serious problem in China, the prevalence of which stays at a high level and shows an upward trend. The target of this study was to explore the factors associated with myopia in Chinese children. Methods: A cross-sectional analysis in a random sample survey was conducted in Beijing in 2008. The data collected from 15,316 Chinese school students aged 6 to 18 years, randomly selected from 19 schools were evaluated, including noncycloplegic refraction and possible genetic, environmental and behavioral factors, to explore the key risk factors for myopia. Univariate and multiple logistic regression analyses were performed to compare the OR values, and receiver operator characteristic (ROC) curves were generated to compare the differences among the areas under the ROC curves using the method of multiple comparison with the best. Results: Myopia was associated with shorter sleep times versus longer sleep times (adjusted OR = 3.37;95%CI 3.07-3.70), and the multivariate OR for two compared with no parents with myopic was 2.83 (95%CI 2.47-3.24) and 1.95 (95%CI 1.69-2.24) for reading or writing distances less than33 cmcompared to distances greater than33 cm. Controlling for other factors, children that slept for shorter periods of time had significantly more myopic refractions (?1.69D vs ?1.29D for children with longer sleeping time per day). Analysis of the areas under the ROC curves showed five variables with predictable values better than chance: age, sleeping time, reading or writing distance, hours of studying, and parental myopia. Conclusion: It was not surprising, as proved by other studies, that parental myopia, reading or writing distances, time spent on studying or other activities by using eyes were dominant risk factors associated with juvenile myopia. Our findings indicated that hours of sleeping were also closely related to juvenile myopia, in which the underlying mechanism should be explored in the future study.

Mental health status of students’parents during COVID-19 pandemic and its influence factors

Background During the outbreak of COVID-19,the national policy of home quarantine may affect the mental health of parents.However,few studies have investigated the mental health of parents during the COVID-19 pandemic.Aims To investigate the depression,anxiety and stress of the students'parents during the COVID-19 pandemic,and to explore the influence factors,especially the influence of social support and family-related factors.Methods The Generalised Anxiety Disorder-7,Patient Health Questionnaire-9,Perceived Stress Scale-10 and Social Support Rating Scale were applied to 1163 parents to measure the parents'depression,anxiety,stress and social support.Results(1)The detection rates of depression and anxiety in parents were 6.1%and 4.0%.The depression,anxiety and perceived stress of parents in central China were significantly higher than those in non-central China.The anxiety of college students'parents was lower than that of parents of the primary,middle and high school students.The depression,anxiety and perceived stress of parents with conflicts in the family were significantly higher than those with a harmonious family.Other factors that influence parents’depression,anxiety and perceived stress include marital satisfaction,social support,parents*history of mental illness and parenting style,etc.(2)The regression analysis results showed that perceived stress,social support,marital satisfaction,family conflicts,child's learning stage as well as parents'history of mental illness had significant effects on parents'anxiety and depression.Conclusion During the COVID-19 pandemic,the mental health of parents was affected by a variety of factors.Good marital relationships,good social support,family harmony and parents without a history of mental illness may be protective factors for parents*mental health,while perceived stress and child in middle or high school are risk factors for parents’mental health.

Industrial layout reconstruction, the role of local government and variation of pollution distribution in China

In recent years, high-polluting industries have been gradually shifted from the eastern developed regions to the central and western underdeveloped regions in China. Certain environmental regulations have been in place accordingly in various regions, but the pollution in the central and western regions has risen sharply. Based on the data of interprovincial panel in China from 2006 to 2015, this paper calculates high-pollution industry dynamic agglomeration index, environmental pollution agglomeration index and relative environmental regulation intensity index, and uses Generalized Method of Moments to carry out the regression analyses of the whole samples,regional heterogeneity and temporal heterogeneity. The results show that there is an inverted Ushaped relationship between relative environmental regulation and environmental pollution concentration in China. The concentration degrees of industrial wastewater pollution and industrial waste gas pollution are deepened, which are mainly caused by the transfer of highly polluting industries. However, the concentration of industrial solid waste pollution caused by the transfer is not obvious. Furthermore, the deepening of industrialization intensifies the concentration of regional environmental pollution. Environmental Kuznets Curve does exist in China,but it is not significant. The increase of labor cost and quality will reduce the concentration of environmental pollution.

The Impact of Tobacco Taxation Policy on Slim Cigarette Use and the Growing Popularity of Slim Cigarettes in China Since 2014

Introduction: In 2016, China became the largest market for slim cigarettes in the world, selling 68.945 billion sticks. The purpose of this study is to examine the impact of China’s 2015 tobacco taxation policy on slim cigarette consumption and the product’s market trends. Methods: Monthly data on the market share of slim cigarettes and their average price between January 2014 and June 2017 were used to show tobacco market trends and to estimate the impact of the 2015 tobacco tax increase on tobacco consumption. Segmented regression analysis was used to estimate the immediate effect of the 2015 tax policy and the time trends in consumption due to the policy change. Findings: After the tobacco tax increase was announced in May 2015, the market share of slim cigarettes initially decreased by 0.2117 (p = 0.067). However, by the third month after the policy change, consumption began to increase, and the market share of slim cigarettes was 1.6 times the normal increase over time. Slim cigarettes gained a 2.02% additional share by the second quarter of 2017 (from 2.58% to 4.60%), controlling for the price difference between slim cigarettes and regular cigarettes. The coefficient of the share and the price ratio (slim cigarettes/regular cigarettes) was ?0.7536 (p = 0.0044), suggesting that slim cigarettes are a substitute for regular cigarettes. Estimates also show that after the tax increase was implemented, consumption of slim cigarettes increased almost three times the normal consumption rate (0.0069 versus 0.0024). Conclusion: The slim cigarette industry in China has grown rapidly in recent years. The 2015 tax increase has had only minimal or short-term impact on reducing the growing popularity of slim cigarettes. Since slim cigarettes are a substitute for regular cigarettes, more empirical research is urgently needed to study the health impacts of slim cigarette use and the impact of tobacco control policies on slim cigarette consumption.

Ecological Planning and Design of Urban Green Space System of Sanya City

The construction of International Tourism Island has accelerated the development of Sanya City. The population aggregation and the external extension of urban area have brought a lot of negative effects, such as discontinuities of green space matrix, dysfunction of green wedge permeation, deficiency of eco-corridor, structural imbalance of green space system and so on. The overall layout of Green space system known as "One Belt & Three Bays, One Core & Six Towns, Two Axes & Three Wedges, Two Net Synchronous-construction" strengthens the eco-connection among different groups and green space in central area of the city, and realizes the collaborative construction of both resource corridor and landscape corridor. The eco-layout of green core, green corridor and green patch helps keep the integrity of large vegetation patches, enhances the eco-connection of different types of green space and improves finger-shaped network of urban green space. The most efficient way to promote the circulation of urban ecosystem and the positive development of Sanya City is to plan multilevel and three-dimensional eco-space structure and maximize ecological benefits of green space system.

Untying the Two “Deadlocks”of Labor Contract Law Is Necessary for the Recovery of Chinese Economy

Labor Contract Law receives mixed evaluations since its implementation.The call for the amendment is hot and even some scholars regard it as the"tiger in the road"which hinders the economic development. The Central Committee of the Communist Party of China pays high attention to the construction of harmonious labor relation and the amendment has been a top priority. Labor Contract Law leads to two"deadlocks"of which the entrepreneurs are afraid. The first one is that the non-fixed term labor contract cannot be cancelled and the second one is that they must pay the economic compensation at the expiration of contract. These two rules hinder the employment enthusiasm of entrepreneurs. The current laws have excessive expectation for the non-fixed term labor contract and too strict regulations; as for the economic compensation at the expiration of contract, it increases the enterprise cost. The amendment of these two articles will benefit the recovery of Chinese economy and make the labor relation more harmonious.

Impact of Regional Economy on Internal Migration in Yangtze Delta:Based on Panel Data

Metropolitan Shanghai, in Yangtze River Delta (YRD), plays undoubtedly the leading role in the economic development in China, and becomes one of the most important population con- gregation areas. It is also widely regarded as the sixth uprising urban agglomeration in the world. Based on the quantitative stud- ies on basic socioeconomic and demographic profile on the num- ber and transition of population, this paper concluded that the migration is the key factor for population dynamics in YRD. Then, what are the regional economic factors affecting the migration of different cities in YRD? The panel data show that the different wage level is the most important factor that affects the immigra- tion in YRD. Moreover, the ratio of industry sector and service sector has an impact on attracting immigration. However, per-capital GDP and the share of foreign direct investment (FDI) to GDP have dual-side impact: not high per-capital GDP and FDI bring the high immigration.

Points System:An Universal Beneficial System with Multiple Objectives of Reform on Household Registration System

Reform of China's Household Registration system(HRS) has been entering a new stage and deserves us to research.The paper argues that reform of HRS should have multiple objectives.It examines various local efforts and practices of the reform and claims that the point system is one of the most feasible alternative systems for the HRS that can fit those multiple reform objectives.The system could also be treated as the new institutional basic for public welfare provision and rights allocation,and a new governance means for population issues as well in China's transitional period.

Market Access and the Border Effect of China's Labor Migration

：This paper introduces a new economy geography index, market access, to analyze the dynamic mechanism of labor migration in China based on the sample data from China＇s labor cross-region flow 1998 -- 2008. The empirical test prove the reversed U-shape of ＂Market access -Wage - Migration＂ and finds that market access in early period of China＇s reform increased labor migration significantly from peripheral zone to the central area which caused China＇s core-peripheral competition landscape. However with the appearance of Lewis turning point＂and disappearance of demographic dividend, the M-W-M mechanism tends to weaken.

The potential biological mechanisms of obesity effects on depression: A systematic review of the literature and knowledge mining

Depression and obesity (BMI ≥ 30) have been recognized as major public health issues worldwide. Although they have traditionally been compartmentalized as separate physical and emotional health conditions, evidence has suggested interactions and common pathways between them, implying that they probably shared common underlying biological mechanisms. By a systematic review of the literature and knowledge mining, we explore a potential biological mechanism of obesity effects on depression. Bioactivators in the body of obesity including adiponectin, leptin and its receptors, ghrelin, endocannabinoids and orexin receptors may contribute to depression by the hypothalamic pituitary adrenal axis, psycho-neuro-immunological system, neurovegetative system and brain areas control of mood and emotion such as hippocampus, cortex and amygdala.

Survey Reveals Farmers'Perceptions of Modern Life

Through a statistical analysis of the results of a field survey conducted in a moderately remote suburb of Shanghai,this article investigates the common problems and concerns that farmers are facing during the process of marketization. In evaluating the level of rural development,farmers pay more attention to social security and their living conditions than an increase in income. Whilst playing a prominent role in the development of the rural economy and environmental governance, the government has failed to adequately cultivate community culture and public spiritual life. The government policies on building a new socialist countryside focus on those issues of most concern to farmers: income,employment,education,social security and rural environmental governance,whilst neglecting the cultural life of farmers.

Stage Features and Influence Factors of Urbanization in Hainan

Hainan has witnessed rapid urbanization since the early twenty-fi rst century. To defi ne development stages and dominant factors of urbanization, this paper adopted such quantitative research methods as principal component analysis(PCA) and regression analysis, established a composite index system including population, land use, economic and social factors, and investigated urbanization process of Hainan Province using SPSS19.0. The results showed that the comprehensive influence obtained from the composite index system has had increasing impact on the urbanization of Hainan since 2000, and showed obvious stage features. As a whole, the urbanization history falls into 3 stages: slowing down, improving, and rapidly accelerating, and dominant factors in each stage vary greatly.

Elasticity Ratio of Resource Consumption and the Resource Consumption

Today the resources are becoming scarcer, which should not be regarded as unexhausted any more. Correspondingly, the production would be constrained by the scarcity of resources clearly. Then the economic researchers would pay much more attention to reducing the consumption of natural resources in the future. Therefore this paper brings foreword the conception of elasticity ratio of resource consumption based on the concept of elasticity and analyzes the relationship between the parameters. For the certain relationships between the elasticity ratio of resource consumption and resource consumption, this paper will try to reveal, to keep economy growing while resource consumption reducing, what conditions should be met as to the relationships among resource productivity, its growth rate, energy saving efficiency, economic growth rate and elasticity ratio of resource consumption. This paper proves the relationship between the China＇s energy consumption and economy growth using statistic data from 1978 to 2003.

Effect of job satisfaction on burnout among physicians: A survey study in urban public medical institutions in Hubei province, China

Objectives: Chinese physicians are being loaded with the enormous psychological pressure and so tend to be susceptible to burnout. Little is known on the relationship between job satisfaction and burnout for physicians from urban public medical institutions. We aim to describe the degree of burnout and evaluate the impact of job satisfaction on burnout. Methods: A cross-sectional survey was conducted in March 2010 in Hubei province, central China. The job satisfaction and burnout instruments were obtained by modifying the Chinese Physicians’ Job Satisfaction Questionnaire and the Chinese Maslach Burnout Inventory, respectively. Such statistical methods as one-way ANOVA, Pearson correlation coefficient and GLM-univariate were employed. Results: The observed mean and burnout incidence on emotional exhaustion (3.45 ± 0.75, 66.99%) and depersonalization (3.56 ± 0.76, 68.64%) were high, but reduced personal accomplishment (2.18 ± 0.56, 5.79%) was low. The distribution of the degree of overall burnout was: 3.2% (severe), 48.2% (moderate), 35.4% (mild) and 13.2% (zero). Less the development level of urban area and higher the grade of medical institution was, more severe physicians’ burnout was. Job-itself satisfaction (b1 = -0.166, b2 = -0.056), job rewards satisfaction (b1 = -0.084, b2 = -0.150) and medical practicing environment satisfaction (b1 = -0.096, b2 = -0.319) were identified as significant negative predictors of emotional exhaustion (R2 = 0.35) and also of depersonalization (R2 = 0.46). Only the job-itself satisfaction (b3 = -0.355) contributed to reduced personal accomplishment (R2 = 0.40). significantly Conclusions: Occupational burnout, especially emotional exhaustion and depersonalization, is common and serious among Chinese physicians. Several, but not all dimensions of job satisfaction, which prove to have predictive effects on burnout, should be paid more attention to in order to improve physicians’ psychological health.

A Comprehensive Programme for the Resettlement of Climate Refugees

The placement of environmentally displaced persons is imminent.Involving as many countries as possible in the resettlement of environmentally displaced persons,while protecting their culture and human rights,are the primary goal of the resettlement program.However,countries may refuse to participate in resettlement programs if their interests are not fully considered.The rights of the environmentally displaced persons cannot be protected.The model involves the interests of all parties to ensure the wide participation of all countries in the world.Then,we use quantitative assessment to assess the risk of cultural loss and protect culture and human rights of environmentally displaced persons by controlling this risk.Firstly,in order to calculate the number of people who are likely to be environmentally displaced persons in the future,we build a prediction model based on Markov Chain.By analyzing the average altitude of each country and the predicted sea level rise,we calculate the number of countries likely to be submerged over time.Combining the projected future population of each country,we calculate the total number of people at risk of becoming environmentally displaced persons.Secondly,we link the number of environmentally displaced persons that countries should place with the two goals of human rights protection.Establish Double-Score model to allocate the number of people that each country should place reasonably.The model takes into account countries’carbon emissions and their suitability for migration.The two integral indexes in the model are as follows:Score of carbon dioxide emission.The higher a country’s score,the more responsibility it has to accommodate environmentally displaced persons.The index is converted from the country’s per capita carbon emissions and total carbon emissions,using the Paris Climate Agreement’s calculation of carbon emissions.Score of suitability for immigration.The lower the Score of a country,the higher the Score of carbon emission can be deducted.Meanwhile,the better a country’s cultural and human rights protection of environmentally displaced persons,the higher the score.We encourage countries to actively protect the human rights and culture of refugees.As a part of its commitment to the Paris Climate Agreement,the countries of the world must keep their total score below the set threshold.

Analysis on the Characteristics and Changing Trends of Population Structure in Megalopolis : the Case of Beijing

Taking Beijing as an example and based on the census data,macro-level population statistical data and 2004~2013 marriage registration data,this paper makes a contrastive analysis on the characteristics and changing trends of local residents,migrants and temporary migrants. Relative to the local residents,the migrants generally have household registry of central districts and higher educational level and occupational layer. Temporary migrants have relatively complicated population structure but differentiate during the process of marriage matching. 'Two-place marriages'form a stable group of new permanent migrants and meanwhile imply a sizable group of latent dependent migrants. This will produce great infl uences on the general population structure and the aging process,which may also lead to some confl icts and problems. The government should be prepared with policy responses so as to promote the benign development of population diversifi cation in megalopolis.

A New Method for Comprehensive Evaluation of Air Quality in Urban Agglomeration

In this study, a new method for a comprehensive evaluation of air quality in urban agglomerations was developed based on a prototype used to solve the spatial Steiner-Weber point. With this method, the air quality information of each city in the city group is aggregated into an optimal gathering point, and then the air quality of the city group is then dynamically evaluated each year. According to the relevant data of the China Statistical Yearbook 2018, we applied this method to aggregate the air quality indices of the major cities in the Beijing-Tianjin-Hebei urban agglomeration from 2014 to 2017. Using the plant growth simulation algorithm (PGSA), the optimal assembly points were calculated to be of a higher accuracy, compared to the traditional mean value aggregation method. Finally, the air quality of the Beijing-Tianjin-Hebei urban agglomeration during each year was evaluated dynamically based on the obtained assembly points. The results show that the air quality of the urban agglomeration is ranked as follows: Y2016Y2015Y2017Y2014.
