Analysis of the Employment Situation of Non Private Enterprises in Various Regions of China

In the past 30 years, Chinese enterprises have been a hot topic of discussion and concern among the general public in terms of economic and social status, ownership structure, business mechanism, and management level. Solving the problem of employment for the people is an important prerequisite for their peaceful living and work, as well as a prerequisite and foundation for building a harmonious society. The employment situation of private enterprises has always been of great concern to the outside world, and these two major jobs have always occupied an important position in the employment field of China that cannot be ignored. With the establishment of the market economy system, individual and private enterprises have become important components of the socialist economy, making significant contributions to economic development and social progress. The rapid development of China’s economy, on the one hand, is the embodiment of the superiority of China’s socialist market economic system, and on the other hand, it is the role of the tertiary industry and private enterprises in promoting the national economy. Since the 1990s, China’s private enterprises have become a new economic growth point for local and even national countries, and are one of the important ways to arrange employment and achieve social stability. This paper studies the employment of private enterprises and individuals from the perspective of statistics, extracts relevant data from China statistical Yearbook, uses the relevant knowledge of statistics to process the data, obtains the conclusion and puts forward relevant constructive suggestions.

Land Use and Land Cover Change on Slope in Qiandongnan Prefecture of Southwest China

This study uses DEM （Digital Elevation Model） data and remote sensing maps of the study area in 1993, 1999, and 2009 to analyze the slope gradient change of land use patterns in Qiandongnan Prefecture, Guizhou province, China. The land use data were classified into five types, forest, farmland, grassland, water and built-up, the slope gradients were divided into four grades. Indices for analyzing land use features were defined by their proportions, transformation matrixes, land use degree and changes The results showed that all land use types can be found at every gradient. Generally, with the slope degree increased, the area of forest being augmented as well, while the area of the other land use types （farmland, grassland and build-up） declined. Moreover, a mass of farmland were shifted from other land use types from o° to 25°, while a quantity of forest were transformed from the other land use types on 〉 25° from 2993 to 2009. In terms of land use degree and changes, the area of farmland and buildup land use types decreased when slope degree increased. Finally, we calculated the five landscape pattern metrics： Patch Density （PD） value, Largest Patch Index （LPI）, Shannon＇s Diversity Index （SHDI）, Area-Weighted Mean Shape Index （AWMSI） and Contagion Index （CONTAG）. The results of metricsanalysis showed that PD values, SHDI values and CONTA values had a similar variation trend, that is, they decreased when slope degree increased. There was no obvious variation trend on LPI value.

Ethnobotany and diversity of medicinal plants used by the Buyi in eastern Yunnan, China

The Buyi are a socio-linguistic group in Yunnan Province of southwest China that have a long history of using medicinal plants as part of their indigenous medical system.Given the limited written documentation of the Buyi indigenous medical system,the objective of this paper is to document the medicinal plants of the Buyi and associated traditional knowledge and transmission.Field research was conducted in four villages in Lubuge Township of Luoping County in Yunnan Province using ethnobotanical methodologies including participatory observation,semi-structured interviews,key informant interviews,and focus group discussions to elicit information on medicinal plants.In total,120 informants(including 15 key informants who are healers)were interviewed.This study found that a total of 121 medicinal plant species belonging to 64 families are used by the Buyi including by local healers to treat different diseases.Among the medicinal plants recorded in this study,56 species(46%)have not previously been documented in the scientific literature as having medicinal value,highlighting the pressing need for ethnobotanical documentation in indigenous communities.The most frequently used medicinal part was the leaf(24.9%of documented plants),and the most common preparation method was decoction(62.8%of medicinal).Medicinal plants were mainly used to treat rheumatism(12.4%of plants),trauma and injuries(9.6%).The documented plants are also used for other non-medicinal purposes including food,fodder,fencing,and ornamental.In addition,35 of the medicinal plants are considered poisonous and are used by local Buyi healers for medicine.The traditional Buyi beliefs and practices associated with the documented medicinal plants likely contributes to their conservation in the environments and around Buyi communities.This study further highlights that ethnomedicinal knowledge of the Buyi is at risk of disappearing due to increased introduction and use of modern medicine in Buyi communities,livelihood changes,rapid modernization,and urbanization.Research,policy,and community programs are urgently needed to conserve the biocultural diversity associated with the Buyi medical system including ethnobotanical knowledge towards supporting both environmental and human wellbeing.

Temperature effect on luteinizing hormone secretion of Eurasian Skylark(Alauda arvensis) and Great Tit(Parus major) in China

Background: Global warming caused trophic mismatch has affected the breeding success, and even the survival, of some bird species.The ability of birds to accelerate their reproduction onset in the warmer spring could be critical to the survival of some species.The activation of the reproductive endocrine axis in birds is a key physiological process that determines the onset of reproduction.Could birds change the HPG axis endocrine rhythm under the temperature rising condition?Methods: Using plasma LH level as an indicator of initiation of the reproductive endocrine and artificially controlling temperature, we compared variations in the timing of activation of the reproductive endocrine axis in response to temperature in two Chinese bird species, the Eurasian Skylark(Alauda arvensis) and the Great Tit(Parus major) at both the population and individual levels.Results: At the population level, temperature only significantly influenced LH level in the Eurasian Skylark, and had no significant effect on the LH levels in the Great Tit.Mean LH level of Eurasian Skylarks in the 20 ℃ group was higher than that of those in the 15 ℃ group throughout the experiment.Large individual variations in the timing of peak LH levels were observed in the high and the low temperature groups of both Eurasian Skylarks and Great Tits.Conclusions: These results indicate that the effects of temperature differ among species.Meanwhile, there appears to be a degree of within population polymorphism in the timing of reproductive endocrine axis activation in some species.This polymorphism could provide the variation required for bird populations to cope with the possible change of their food peak under the climate warming condition.

Coarse woody debris features of a warm temperate deciduous broad-leaved forest,northern China

Stocking and structural composition of a deciduous broad-leaved forest were determined to predict coarse woody debris quantity by quantifying the empirical relationships between these two attributes.The most ecologically significant families by stem density were Salicaceae,Betulaceae,Fagaceae,and Aceraceae.P opulus davidiana was the most dominant species followed by B etula dahurica,Quercus mongolica,and Acer mono.The four species accounted for 69.5%of total stems.Numerous small-diameter species characterized the coarse woody debris showing a reversed J-shaped distribution.The coarse debris of P.davidiana,B.dahurica,and Q.mongolica mainly comprised the 10–20 cm size class,whereas A.mono debris was mainly in the 5–10 cm size class.The spatial patterns of different size classes of coarse woody debris were analyzed using the g-function to determine the size of the tree at its death.The results indicate that the spatial patterns at the 0–50 m scale shifted gradually from an aggregated to a random pattern.For some species,the larger coarse debris might change from an aggregated to a random distribution more easily.Given the importance of coarse woody debris in forest ecosystems,its composition and patterns can improve understanding of community structure and dynamics.The aggregation pattern might be due to density dependence and self-thinning effects,as well as by succession and mortality.The four dominant species across the different size classes showed distinct aggregated distribution features at different spatial scales.This suggests a correlation between the dominant species population,size class,and aggregated distribution of coarse woody debris.

The decoupling relationship between China’s economic growth and carbon emissions from the perspective of industrial structure

This study analyses the decoupling relationship between energy-related CO_(2) emissions and economic growth in China from 2000-2017 from the perspective of industrial structure using the LMDI method and Tapio decoupling model.The decoupling driving force was decomposed into emission,energy intensity,industrial structure,economic activity,and population factors.Studies have shown that the restructuring of China’s industries has not led to a significant increase in CO_(2) emissions.Specifically,from 2000 to 2017,China’s economic development and carbon emissions are generally in a weak decoupling state.Strong decoupling occurred from 2000 to 2001 and from 2013 to 2016.The industrial structure change has a substantial impact on the primary sector(agriculture),followed by the tertiary sector(services),while the impact on the secondary sector(industry)is negligible.The GDP contribution of the primary industry is small,but it is an indispensable guarantee for a country.With the development of agricultural mechanization and technology,human and animal power in this industry has been decreasing year by year,and large-scale planting has improved energy efficiency.The level of technology should be continuously strengthened to promote the decoupling of carbon emissions.The contribution of the secondary industry to GDP is around 40%,but the secondary industry accounts for more than 80%of CO_(2) emissions,mainly caused by the use of fossil energy.In 2017,fossil energy still accounted for about 86.2%of China’s energy consumption,so fossil energy remains the most critical energy source for China’s economic development.Coal,in turn,accounts for the largest share of fossil energy consumption.Therefore,emphasis should be placed on increasing technological innovation and conversion from fossil to non-fossil energy sources.The Chinese government considers the service industry a new engine for sustainable social and economic development.The contribution of the tertiary sector to GDP has increased from 2000 to 2017,followed by resource and environmental problems.Although the current share of CO_(2) emissions directly caused by the tertiary sector is not high,as the tertiary sector continues to grow,plans to reduce the decoupling of carbon emissions from the tertiary sector should be made in advance.

A Comparison between the Corporation Law System of the United States and the Corporation Law of China

The corporation law system of the United States is greatly different from the related rules and regulations of China.In this paper,the two sides are compared only in terms of director’s duties to corporation.Because of the demand of corporation for business specialization,the shareholders of corporation are divorced from the management of corporation affairs,and thus director’s duty of loyalty and duty of care to corporation are especially important for the interests of the corporation.In the stipulation of China for the two duties,however,specific discretion standards are absent,but also unreasonably aggravated duties of director have emerged.By comparing with the corporation law of the United States,the judgment for the reasonable and unreasonable aspects of Chinese corporation law is conducive to improve the duties of director in China.

Identifying the priority areas for enhancing the ecosystem services in hilly and mountainous areas of southern China

Ecosystem services can be enhanced through ecological restoration,industrial structure adjustment,land-use optimization,and agricultural and forestry ecosystem transformation.The ecosystem services in hilly and mountainous areas of southern China are crucially needed to be enhanced since these regions are important ecological functional zones in China.However,due to its large area,it is not possible to simultaneously upgrade the ecosystem services for all areas,and therefore,priority areas need to be selected to individually upgrade the ecosystem service function.In this study,via an approach of combining remote sensing,geographic information system,and spatial statistics,we identify the priority areas that need to be upgraded based on the analysis of ecological sensitivity,importance of ecosystem service function,and decreased degree in ecosystem services.For five counties in hilly and mountainous areas of southern China,only less than 2% of the total area was identified as the first priority area;its land-use compositions were analyzed and recommendations on how to enhance ecosystem service were suggested.This approach overcomes the conflict and contradiction issues associated with identifying priority areas in previous studies and solves the problems of high cost or difficult implementation of priority areas.

Study on Regulatory Issues of Environmental Laws of Rural Tourism in China

In recent years, rural tourism in China vigorously developed, which promoted economic and social development in rural area. However, serious environmental problems appeared in the development process of rural tourism since rural tourism lacked effective and comprehensive super- vision. These environmental problems included environmental pollution and ecological damage. However, environmental legal system about rural tourism had many problems, such as the lagged legislation, the absence of law enforcement supervision, imperfect judicial system and weak law- abiding awareness. Therefore, it became the solution to solve environmental problems brought by rural tourism in China, and was also the safe- guard for promoting sustainable development of rural tourism in China to establish a sound legal system for rural tourism, implement strict law en- forcement supervision of rural tourism, build litigation system of environmental public interest and enhance law-abiding awareness of rural tourism. For legal defects of regulating rural tourism and its induced environmental problems in China, we tried to perfect regulation of environmental law for rural tourism in China.

Cyclical Patterns of China’s Reform and Their Implications for the New Era

After taking stock of China's four-decade reforms, this paper identifies the cyclical patterns of China's reforms, which consist of an intermediate cycle and three short cycles. The purpose of reform is to adjust the changing relations of production to changing productivity. China has adopted a gradualist approach of reform, and reform cycles have coincided with economic cycles. The cyclical changes of reform are of great significance to comprehensively deepening reforms in the new era: Downward pressures of the economy present the best window period for reform;a new cycle of reform will unveil a new economic cycle as well;the people's support is essential to pushing forward the cyclical movements of reform;and top-down design is essential to deepen reforms on all fronts.

Incubation temperature induced developmental plasticity of cold responsive physiological phenotypes in Japanese Quails

Embryonic development is a critical period for phenotype formation.Environmental variation during embryonic development can induce changes in postnatal phenotypes of animals.The thyroxine secretion and aerobic metabolic activity of small birds are important phenotypes closely related to their winter survival.In the context of climate change,it is necessary to determine whether temperature variation during incubation in birds leads to developmental plasticity of these cold responsive phenotypes.We incubated Japanese Quail(Coturnix japonica)eggs at 36.8℃,37.8℃,and 38.8℃,and raised the chicks to 35-day old at 22℃with same raising conditions,then all the quails were exposed to gradually temperature dropping environment(from 15℃to 0℃).After cold treatment,serum T3 level,resting metabolic rate,skeletal muscle and liver metabolomes of the birds were measured.The serum T3 levels were significantly lower in the 38.8℃group and significantly higher in the 36.8℃group compared to the 37.8℃group.The metabolic rate in the 38.8℃group was significantly lower compared to the 37.8℃group.Compared with the 37.8℃group,metabolites involved in the tricarboxylic acid cycle in the liver were significantly lower in the 38.8℃group,and metabolites related to lipid oxidation metabolism and fatty acid biosynthesis were significantly lower in the skeletal muscles in the 38.8℃group but significantly higher in the 36.8℃group.These results indicate that incubation temperature variation can lead to developmental plasticity in cold responsive physiological phenotypes.Higher incubation temperature may impair the capacity of birds coping with cold challenge.

Dual mass spectrometry imaging and spatial metabolomics to investigate the metabolism and nephrotoxicity of nitidine chloride

Evaluating toxicity and decoding the underlying mechanisms of active compounds are crucial for drug development.In this study,we present an innovative,integrated approach that combines air flowassisted desorption electrospray ionization mass spectrometry imaging(AFADESI-MSI),time-of-flight secondary ion mass spectrometry(ToF-SIMS),and spatial metabolomics to comprehensively investigate the nephrotoxicity and underlying mechanisms of nitidine chloride(NC),a promising anti-tumor drug candidate.Our quantitive AFADESI-MSI analysis unveiled the region specific of accumulation of NC in the kidney,particularly within the inner cortex(IC)region,following single and repeated dose of NC.High spatial resolution ToF-SIMS analysis further allowed us to precisely map the localization of NC within the renal tubule.Employing spatial metabolomics based on AFADESI-MSI,we identified over 70 discriminating endogenous metabolites associated with chronic NC exposure.These findings suggest the renal tubule as the primary target of NC toxicity and implicate renal transporters(organic cation transporters,multidrug and toxin extrusion,and organic cation transporter 2(OCT2)),metabolic enzymes(protein arginine N-methyltransferase(PRMT)and nitric oxide synthase),mitochondria,oxidative stress,and inflammation in NC-induced nephrotoxicity.This study offers novel insights into NC-induced renal damage,representing a crucial step towards devising strategies to mitigate renal damage caused by this compound.

Pharmacometabolomics and mass spectrometry imaging approach to reveal the neurochemical mechanisms of Polygala tenuifolia

Polygala tenuifolia,commonly known as Yuanzhi(YZ)in Chinese,has been shown to possess antiinsomnia properties.However,the material basis and the mechanism underlying its sedative-hypnotic effects remain unclear.Herein,we investigated the active components and neurochemical mechanism of YZ extracts using liquid chromatography tandem mass spectrometry(LC-MS/MS)-based pharmacometabolomics and mass spectrometry imaging(MSI)-based spatial resolved metabolomics.According to the results,17 prototypes out of 101 ingredients in the YZ extract were detected in both the plasma and brain,which might be the major components contributing to the sedative-hypnotic effects.Network pharmacology analysis revealed that these prototypes may exert their effects through neuroactive ligand-receptor interaction,serotonergic synapse,dopaminergic synapse,and dopaminergic synapse,among other pathways.LC-MS/MS-based targeted metabolomics and Western blot(WB)revealed that tryptophan-serotonin-melatonin(Trp-5-HT-Mel)and tyrosine-norepinephrine-adrenaline(Tyr-Ne-Ad)are the key regulated pathways.Dopa decarboxylase(DDC)upregulation and phenylethanolamine Nmethyltransferase(PNMT)downregulation further confirmed these pathways.Furthermore,MSI-based spatially resolved metabolomics revealed notable alterations in 5-HT in the pineal gland(PG),and Ad in the brainstem,including the middle brain(MB),pons(PN),and hypothalamus(HY).In summary,this study illustrates the efficacy of an integrated multidimensional metabolomics approach in unraveling the sedative-hypnotic effects and neurochemical mechanisms of a Chinese herbal medicine,YZ.

MULTIPLICITY OF NORMALIZED SOLUTIONS FOR THE FRACTIONAL SCHR?DINGER-POISSON SYSTEM WITH DOUBLY CRITICAL GROWTH

In this paper,we are concerned with solutions to the fractional Schrodinger-Poisson system■ with prescribed mass ∫_(R^(3))|u|^(2)dx=a^(2),where a> 0 is a prescribed number,μ> 0 is a paremeter,s ∈(0,1),2 <q <2_(s)^(*),and 2_(s)^(*)=6/(3-2s) is the fractional critical Sobolev exponent.In the L2-subcritical case,we show the existence of multiple normalized solutions by using the genus theory and the truncation technique;in the L^(2)-supercritical case,we obtain a couple of normalized solutions by developing a fiber map.Under both cases,to recover the loss of compactness of the energy functional caused by the doubly critical growth,we need to adopt the concentration-compactness principle.Our results complement and improve upon some existing studies on the fractional Schrodinger-Poisson system with a nonlocal critical term.

New insights into the interactions between the gut microbiota and the inflammatory response to ulcerative colitis in a mouse model of dextran sodium sulfate and possible mechanisms of action for treatment with PE&AFWE

Background:Inflammatory bowel disease(IBD),comprising Crohn's disease(CD)and ulcerative colitis(UC),is a heterogeneous state of chronic intestinal inflammation.Intestinal innate immunity,including innate immune cells,defends against pathogens and excessive entry of gut microbiota,while preserving immune tolerance to resident intestinal microbiota,and may be characterized by its capacity to produce a rapid and nonspecific reaction.The association between microbiota dysbiosis and the pathogenesis of IBD is complex and dynamic.When the intestinal ecosystem is in dysbiosis,the reduced abundance and diversity of intestinal gut microbiota make the host more vulnerable to the attack of exogenous and endogenous pathogenic gut microbiota.The aim of our study was to comprehensively assess the relationship between microbial populations within UC,the signaling pathways of pathogenic gut microbe therein and the inflammatory response,as well as to understand the effects of using PE&AFWE(poppy extract[Papaver nudicaule L.]and Artemisia frigida Willd.extract)on UC modulation.Methods:A UC mouse model was established by inducing SPF-grade C57BL/6 mice using dextrose sodium sulfate(DSS).Based on metagenomic sequencing to characterize the gut microbiome,the relationship between gut microbiota dysbiosis and gut microbiota was further studied using random forest and Bayesian network analysis methods,as well as histopathological analysis.Results:(1)We found that the 5 gut microbiota with the highest relative abundance of inflammatory bowel disease UC model gut microbiota were consistent with the top 5 ranked natural bacteria.There were three types of abundance changes in the model groups:increases(Chlamydiae/Proteobacteria and Deferribacteres),decreases(Firmicutes),and no significant changes(Bacteroidetes).The UC model group was significantly different from the control group,with 1308 differentially expressed species with abundance changes greater than or equal to 2-fold.(2)The proportion of the fecal flora in the UC group decreased by 37.5%in the Firmicutes and increased by 14.29%in the proportion of Proteobacteria compared to the control group before treatment.(3)The significantly enriched and increased signaling pathways screened were the'arachidonic acid metabolic pathway'and the'phagosomal pathway',which both showed a decreasing trend after drug administration.(4)Based on the causal relationship between different OTUs and the UC model/PE&AFWE administration,screening for directly relevant OTU networks,the UC group was found to directly affect OTU69,followed by a cascade of effects on OTU12,OTU121,OTU93,and OTU7,which may be the pathway of action that initiated the pathological changes in normal mice.(5)We identified a causal relationship between common differentially expressed OTUs and PE&AFWE and UC in the pre-and post-PE&AFWE-treated groups.Thereby,we learned that PE&AFWE can directly affect OTU90,after which it inhibits UC,inhibiting the activity of arachidonic acid metabolic pathway by affecting OTU118,which in turn inhibits the colonization of gut microbiota by OTU93 and OTU7.(6)Histopathological observation and scoring(HS)of the colon showed that there was a significant difference between the model group and the control group(p<0.001),and that there was a significant recovery in both the sulfasalazine(SASP)and the PE&AFWE groups after the administration of the drug(p<0.0001).Conclusion:We demonstrated causal effects and inflammatory metabolic pathways in gut microbiota dysbiosis and IBD,with five opportunistic pathogens directly contributing to IBD.PE&AFWE reduced the abundance of proteobacteria in the gut microbiota,and histopathology showed significant improvement.

Gene editing and overexpression of soybean miR396a reveals its role in salinity tolerance and development

MicroRNAs(miRNAs)are versatile regulators of gene expression at both the transcription and posttranscription levels.The microRNA miR396 plays vital roles in growth,development,and resistance to abiotic stresses in many plant species.However,the roles and functions of miR396 in soybeans are not well understood.Here,we report that Gm-miR396a influences soybean development and salinity tolerance.We found that soybean miR396a was responsive to salt stress.Gm-miR396a gene-edited lines(miR396a-GEs),created using CRISPR/Cas9,exhibited more branches,higher grain yields,and greater salinity tolerance than control plants.The transcripts in lines with altered abundance of miR396a-GE were significantly enriched for biological processes related to hormone regulation.Overexpression of the Gm-miR396a precursor(pre-miR396a-OE)resulted in developmental deficiencies including dwarfness,abnormal inflorescences and flowers,smaller and fewer seeds,and small leaves with larger and more numerous stomata.Transcriptome analysis indicated photosynthesis-related genes were downregulated in pre-miR396a-OE plants.These results contribute valuable insights into the function of GmmiR396a in soybeans and hold promise for enhancing soybean yield and salinity tolerance through germplasm innovation.

Macro Characteristics of Human Rights Legal Principles for Ethnic Minorities in New China

In this paper, ethnic minorities refer to the 55 minorities other than the Han ethnic group with- in the borders of the People＇s Republic of China; human rights mean the human rights connotations within the ken of international human rights laws; legal principles mean the principles that all authoritative organizations, legislative organs, administrative departments, judicial organs and other departments should obey.

A Nano-Micro Engineering Nanofiber for Electromagnetic Absorber,Green Shielding and Sensor

It is extremely unattainable for a material to simultaneously obtain efficient electromagnetic(EM)absorption and green shielding performance,which has not been reported due to the competition between conduction loss and reflection.Herein,by tailoring the internal structure through nano-micro engineering,a NiCo2O4 nanofiber with integrated EM absorbing and green shielding as well as strain sensing functions is obtained.With the improvement of charge transport capability of the nanofiber,the performance can be converted from EM absorption to shielding,or even coexist.Particularly,as the conductivity rising,the reflection loss declines from −52.72 to −10.5 dB,while the EM interference shielding effectiveness increases to 13.4 dB,suggesting the coexistence of the two EM functions.Furthermore,based on the high EM absorption,a strain sensor is designed through the resonance coupling of the patterned NiCo2O4 structure.These strategies for tuning EM performance and constructing devices can be extended to other EM functional materials to promote the development of electromagnetic driven devices.
