With the rapid development of economy, the increasing number of motor vehicles and the total road mileage, which leads to the increasingly prominent traffic safety problems. In order to explore the quantitative relationship between the built environment and the risk of urban road traffic safety, this paper reconstructs the built environment system based on the '5D' element model of the built environment combined with the factors influencing traffic safety risks, and describes the built environment from multiple aspects such as density, diversity &traffic design etc, and then build the gradient lift decision tree model to explore the importance and dependency of variables. The empirical analysis selects a district in Chongqing as the research unit, and the results show that: the RMSE the model was 0.0036, the MAPE was 1.9%, and the determination coefficient R2 was 0.84. GBDT algorithm results shows: the cumulative importance of population density, road facilities, intersection density, secondary road and branch road density, average intersection distance, land use mix, and economic density reaches 77.87%. Some variables show obvious nonlinearity and threshold effect. [ABSTRACT FROM AUTHOR]

With the application of intergenerational theory as its analytical framework, this paper seeks to provide new insights into the social construction of sugar-sweetened food and food practices in the context of contemporary urban China, drawing on 16 months' in-depth qualitative research in the city of Chongqing. From an intergenerational perspective, it argues that although adults and children both typically construct sugar-sweetened food as "bad" for health based on the logic of its biological meaning, there are more generational differences in the understandings of sociocultural meanings associated with these foods, which are the main reasons may lead to intergenerational conflict. Caregivers tend to regard their control of children's sugar-sweetened food intake as a means to discipline their children's bodies and develop food moralities. However, children themselves are likely to perform sugar-sweetened food practices as a way of socializing and sometimes resisting the control of caregivers. Based on this, this paper further shows that these diverse views are rooted in the tension between caregivers' anxiety about the transmission of food moralities through intensive parenting practices and children's agency in food consumption in contemporary urban China. These findings enhance intergenerational-theoretical research and highlight the need to move beyond the analytical framework of "behaviour change" in related food and health studies.

Since thermodynamics can describe the energy of matter and its form of storage or transformation in the system, it is introduced to resolve the uncertain decision-making problems. The paper proposes the thermodynamic decision-making method which considers both the quantity and quality of the probabilistic linguistic decision information. The analogies for thermodynamical indicators: energy, exergy and entropy are developed under the probabilistic linguistic circumstance. The probabilistic linguistic thermodynamic method combines the regret theory which captures decision makers' regret-aversion and the objective weight of criterion obtained by the water-filling algorithm. The proposed method is applied to select the optimal solution to respond to the floods in Chongqing, China. The self-comparison is conducted to verify the effectiveness of the objective weight obtained by the water-filling algorithm and regret theory in the probabilistic linguistic thermodynamic method. The reliability and feasibility of the proposed method are verified by comparative analysis with other decision-making methods by some simulation experiments and non-parametric tests.

The city of Chongqing in southwestern China has adopted a systematic set of urbanization policies since the late 2000s. Due to their emphasis on the role of the government and their scale, they deserve close attention. Yet, few studies have examined both positive and negative impacts of the urbanization policies regarding land acquisition, hukou conversion and urban housing as a complete process from rural migrants' perspective. More longer-term empirical studies focusing on rural migrants' reactions to the urbanization policies are needed. By conducting interviews with rural migrants, this paper aims to fill this gap. The results show that the migration intentions of rural migrants living in public rental housing are well-organized and purposive. The motivations for migration are not exclusively financial, but include the opportunities for better schooling and enhanced family bonds that come with living in public rental housing. Meanwhile, the institutional and social barriers faced by rural migrants were also identified. The goal of the paper is to enrich the understandings of the effects of urbanization policies in China.

The appropriate sizes of scale-breeding industries are causing increasing attention in that rational scale-breeding industries may both meet the meat demand of the market and avoid serious environmental problems. In this paper, the appropriate scales of breeding-type family farms were studied from the perspective of quantifying resource losses. The mathematical models about quantifying resource losses were built, and then the evaluation index system of resource losses was established. More than one hundred family farms in Sichuan province and Chongqing city of China located in the subtropics were selected as research cases and were classified as small-, medium- and large-scale family farms, whose unit resource losses and resource loss rates were both evaluated by the index system. Results show that the unit resource losses and the resource loss rate of medium-scale family farms are the lowest among these three kinds of family farms. Therefore, medium-scale farms are moderate, and then are recommended for scale-breeding industries. Implications: Appropriate sizes are essential for the green development of scale-breeding industries. The external environment factors and internal resource effect should be considered. The unit resource losses and the resource loss rate of medium-scale family farms are the lowest among these three kinds of family farms. Therefore, medium-scale farms are optimistic, and then are recommended for scale-breeding industries. For medium-scale family farms, the scale of 800–999 pigs is optimistic. Furthermore, it is very necessary to adopt green cycle. [ABSTRACT FROM AUTHOR]

A new Chengyuchelys latimarginalis (Xinjiangchelyidae) specimen is reported based on a well-preserved, nearly complete shell from the upper part of the Upper Jurassic Shangshaximiao Formation of Qijiang District, Chongqing Municipality, China. The Xinjiangchelyidae were widely distributed in Asia during the Jurassic and were the dominant turtle group in Asian freshwater ecosystems during the Late Jurassic. The Qijiang specimen adds a new element to the yet poorly known freshwater vertebrate fauna and extends the geographical distribution of C. latimarginalis. This paper discusses the intraspecific variation in C. latimarginalis for the first time. It provides a new insight for studying the evolution, habitat, and diversity of xinjiangchelyids.

Academic discussion of traditional zinc-smelting technology in China has been hampered by a paucity of physical data recovered from early production sites. In recent years, however, the discovery of former zinc-smelting sites in the municipality of Chongqing in south-western China has provided important evidence from archaeological excavations that contribute to the study of this topic. Taking the smelting furnace found at the Linjiangerdui site in Zhong County as an example, this paper introduces and discusses the form, use and maintenance of the zinc-smelting furnace of the Ming Dynasty (AD 1368–1644), and makes a preliminary comparison with the smelting furnaces dating to the Qing Dynasty (AD 1636–1912) unearthed in Shizhu County and the mountainous Hunan Province in an attempt to elucidate the development and evolution of ancient Chinese zinc-smelting technology.

Urban transit systems have differential impacts across population groups, including the perceptions of impacts. Nevertheless, the evaluation of difference in perceived benefits of transport investment is under researched, and few attempts have been made to quantify the extent to which transport provision meets users' requirements. This paper explores how the impact of rail transit on development and regeneration differs across different income groups and migrants, assessing equity dimensions that arise through surveys on residents' perceptions, using evidence from Chongqing, China. The analysis utilises both MANOVA and discriminant analysis. The result shows that the lowest income group perceives they benefit least from the rail transit impacts, while the highest income group perceives they benefit most. There is a significant unequal perceived benefit distribution between migrants and local residents within the low-income groups. Reflections are made on policies and planning interventions which might be introduced to achieve greater social equity in impacts. [ABSTRACT FROM AUTHOR]

The organization of construction in the People's Republic of China has over recent decades undergone radical restructuring. The announcement of Deng Xiaoping's Open Door strategy in 1978 marked the beginning of the transition towards the espoused socialist market economy and the progressive introduction of market mechanisms. Existing research tends to focus on the derivation of "critical success factors" rather than the lived realities of those directly involved. In contrast, the current paper adopts a sensemaking perspective that privileges the transient roles and identities of those involved in the micro-processes of project organizing. The empirical focus lies on the sensemaking narratives of middle managers within three state-owned construction enterprises in the Chongqing city region. The findings illustrate how market mechanisms such as bidding and tendering play out in complex ways involving hybrid arrangements between new and pre-existing ways of working. The terminology of project management is seen to have played a performative role in establishing the "project" as the essential unit around which the socialist market is organized. Middle managers are further found to maintain multiple identities in response to the experienced paradoxes of the socialist market economy. The research provides new insights into the micro-processes of project organizing in China with broader implications for transitional economies elsewhere. [ABSTRACT FROM AUTHOR]

Adopting methods of the questionnaire, matched-guise test and semi-structured interview among different occupational groups of migrants in Chongqing, China, the present study investigates the correlation between dialect competence, dialect attitude and social inclusion. The results show that entrepreneur migrants have the highest dialect competence, followed by labor migrants and intellectual migrants. All the migrants' attitude toward Mandarin Chinese, mainly reflected in the "emotional cognitive" and "social evaluation" dimensions, is significantly more positive than that toward Chongqing dialect. In terms of social inclusion, the entrepreneur migrants rank highest, followed by intellectual migrants and labor migrants. Statistics indicate that there is a significant correlation between migrants' social inclusion and their dialect competence and attitude (in particular, the "emotional cognitive" dimension of their dialect attitude plays an important role in affecting their social inclusion). In addition, the semi-structured interview reveals that the migrants' language environment of working and living is a crucial factor affecting their dialect competence, dialect attitude, and hence their social inclusion. Based on the results, this paper provides suggestions on how to improve migrants' social inclusion from a language planning perspective. [ABSTRACT FROM AUTHOR]

China is a country with frequent geological disasters. The geological disasters in different regions are different, such as earthquakes, landslides, collapses, karst collapses, and ground subsidence. With the development of science and technology and the improvement of engineering technology, the combination of image technology and digital technology is constantly developing. People can improve the accuracy of prediction by studying the characteristics of rock formation under different geological conditions while collecting geological data and sorting various information. And reliability, can more accurately identify poor geological conditions, can increase construction safety and reduce economic losses. Based on the comprehensive CT geological survey data, this paper uses nanomaterials to construct software DEM to model the porous medium of the Yanziyan dangerous rock mass in Jinfo Mountain, Nanchuan District, Chongqing and to estimate the area and volume of the collapse potential area of the high-steep dangerous rock mass parameter.

In a complex urban scene, observation from a single sensor unavoidably leads to voids in observations, failing to describe urban objects in a comprehensive manner. In this paper, we propose a spatio-temporal-spectral-angular observation model to integrate observations from UAV and mobile mapping vehicle platform, realizing a joint, coordinated observation operation from both air and ground. We develop a multi-source remote sensing data acquisition system to effectively acquire multi-angle data of complex urban scenes. Multi-source data fusion solves the missing data problem caused by occlusion and achieves accurate, rapid, and complete collection of holographic spatial and temporal information in complex urban scenes. We carried out an experiment on Baisha Town, Chongqing, China and obtained multi-sensor, multi-angle data from UAV and mobile mapping vehicle. We first extracted the point cloud from UAV and then integrated the UAV and mobile mapping vehicle point cloud. The integrated results combined both the characteristics of UAV and mobile mapping vehicle point cloud, confirming the practicability of the proposed joint data acquisition platform and the effectiveness of spatio-temporal-spectral-angular observation model. Compared with the observation from UAV or mobile mapping vehicle alone, the integrated system provides an effective data acquisition solution toward comprehensive urban monitoring.

The synergetic development level of port and city is an important index to measure the radiation effect of the port. Through systematic analysis and study at the development level of port-city systems in the Chengdu-Chongqing Economic Circle, this paper constructed a synergistics-based synergy degree model and proposed an index system of synergy degree measurement for a port-city complex system based on a coupling coordination degree model. Results show that the ports and cities in the Chengdu-Chongqing Economic Circle are still far from high-level synergetic development. In general, the comprehensive synergetic development level of the ports and cities are rising, in which Chongqing ranks the top and is still in a rising trend. The comprehensive development level of Luzhou and Yibin is also on the rise, but the gap between them and Chongqing is becoming bigger. The synergetic development level of port and city is an important index to measure the radiation effect of port and constructs a synergistics-based synergy degree model for a complex system and proposed an indicator system of synergy degree measurement for a port-city complex system based on a coupling coordination degree model from the perspective of systematics.

The First Egongyan Bridge in Chongqing, China was opened to traffic on December 27, 2000. It carries six-lanes of city traffic and two pedestrian paths, one on each side. It is a 600 m span suspension bridge. It was planned that the two pedestrian paths might eventually be converted to transit tracks in the future. However, with the rapid increase in urban traffic, the deck was transformed into an 8-lane bridge instead. Therefore, a new bridge parallel and adjacent to the old bridge was built for the rail transit. For aesthetic reasons, the city decided that the new bridge should also be a suspension bridge, with the same span length and tower height as the first bridge. The First Egongyan Bridge was a true suspension bridge with main cables anchored to ground anchors. However, the new bridge bridge's proximity to the first bridge necessitated the construction of a self-anchored suspension bridge that did away with a second set of ground anchors. This 600 m span happened to be the world's longest span for a self-anchored suspension bridge. [ABSTRACT FROM AUTHOR]

Parcel-level farmland information contains rich spatial distribution and boundary details, which is crucial for digital agriculture and agricultural resource surveys. However, the spatial complexity and heterogeneity of features resulting from high resolution makes it difficult to obtain parcel-level information quickly and accurately. In addition, existing methods do not sufficiently take into account the spatial topological information, particularly for blurred boundaries. Here, we develop a multi-task network model to extract plot-level cropland information. Specifically, the model consists of a cascaded multi-task network with integrated semantic and edge detection, a refinement network with fixed edge local connectivity, and an integrated fusion model. To validate the performance of the model, two typical tests were conducted in Denmark (Europe) and Chongqing (Asia) with high-resolution remote sensing images provided by Sentinel-2 (10 m) and Google Earth (0.53 m) as data sources. The results show that our proposed model outperforms other baseline models and exhibits higher performance. This study is expected to provide important support for the design of new global agricultural information management systems in the future. [ABSTRACT FROM AUTHOR]

Background: Nuts and algae have been shown to improve BP levels, but their effectiveness is controversial. Aims: This study aims to illustrate the effect of dietary pattern with nuts and algae-less on BP levels in children and adolescents from a cross-sectional study. Methods: A total of 5645 children from the Chongqing Children's Health Cohort, aged 9.34 ± 1.74 years with 52.05% males, were analyzed. Stratified analysis was conducted to explore the differences between the two dietary patterns in urban or rural areas, as well as the differences in different gender. Logistic regression was used to analyze the influence factors of increased BP. And a GLM was used to analyze the influence of the two dietary patterns on systolic blood pressure (SBP, mmHg), diastolic blood pressure (DBP, mmHg), and mean arterial pressure (MAP, mmHg). Results: Children with nuts and algae-less dietary patterns had higher SBP (104.68 ± 10.31 vs 103.81 ± 9.74, P = .006), DBP (64.27 ± 7.53 vs 63.55 ± 7.52, P = .002), and MAP (77.74 ± 7.75 vs 76.97 ± 7.52, P = .001) compared with those children with a balanced diet. After adjusting for covariates, the nuts and algae-less diet was a risk factor for hypertension in children when compared with the balanced diet(OR(95%CI):1.455(1.097,1.930), P = .009). The nuts and algae-less diet has a significant influence on SBP (104.68 ± 10.31 mmHg vs.103.81 ± 9.74 mmHg, P = .006). Stratified analysis by sex showed that nuts and algae-less dietary patterns had a more significant impact on females than males. Conclusion: Nuts and algae-less dietary pattern correlated with increased BP levels in children, and a greater impact on SBP levels was found in females, suggesting that a balanced diet with appropriate nuts and algae should be proposed for children in China.

People's use of the rail transit system varies over space. Previous literature suggests there is a social equity dimension in the distribution of benefits from new urban transit systems, but how this varies spatially is poorly evidenced. The research aims to examine the spatial differences in the use of rail transit and associated transport equity. Using a case study of Chongqing, a geographically weighted regression (GWR) model is used to reveal the spatial variation in parameter estimates, complementing the traditional multivariate global model. The analysis demonstrates the effect of rail transit in facilitating people's travel and mitigating transport-related social inequity, including for those with mobility disadvantages and living in areas with poor access to public transport. The results emphasise the necessity of associated development strategies and transport policies in favour of socially disadvantaged groups, such as low fare levels. Implications for planning interventions are proposed based on the model results. [ABSTRACT FROM AUTHOR]

Clarifying the spatiotemporal distribution and impact mechanism of pollution is the prerequisite for megacities to formulate relevant air pollution prevention and control measures and achieve carbon neutrality goals. Chongqing is one of the dual-core key megacities in Cheng-Yu region and as a typical mountain-city in China, environmental problems are complex and sensitive. This research aims to investigate the exceeding standard levels and spatio-temporal evolution of criteria pollutants between 2014 and 2020. The results indicated that PM10, PM2.5, CO and SO2 were decreased significantly by 45.91%, 52.86%, 38.89% and 66.67%, respectively. Conversely, the concentration of pollutant O3 present a fluctuating growth and found a "seesaw" phenomenon between it and PM. Furthermore, PM and O3 are highest in winter and summer, respectively. SO2, NO2, CO, and PM showed a "U-shaped", and O3 showed an inverted "U-shaped" seasonal variation. PM and O3 concentrations are still far behind the WHO, 2021AQGs standards. Significant spatial heterogeneity was observed in air pollution distribution. These results are of great significance for Chongqing to achieve "double control and double reduction" of PM2.5 and O3 pollution, and formulate a regional carbon peaking roadmap under climate coordination. Besides, it can provide an important platform for exploring air pollution in typical terrain around the world and provide references for related epidemiological research. Implications: Chongqing is one of the dual-core key megacities in Cheng-Yu region and as a typical mountain city, environmental problems are complex and sensitive. Under the background of the "14th Five-Year Plan", the construction of the "Cheng-Yu Dual-City Economic Circle" and the "Dual-Carbon" goal, this article comprehensively discussed the annual and seasonal excess levels and spatiotemporal evolution of pollutants under the multiple policy and the newest international standards (WHO,2021AQG) backgrounds from 2014 to 2020 in Chongqing. Furthermore, suggestions and measures related to the collaborative management of pollutants were discussed. Finally, limitations and recommendations were also put forward. Clarifying the spatiotemporal distribution and impact mechanism of pollution is the prerequisite for cities to formulate relevant air pollution control measures and achieve carbon neutrality goals. This study is of great significance for Chongqing to achieve "double control and double reduction" of PM2.5 and O3 pollution, study and formulate a regional carbon peaking roadmap under climate coordination and an action plan for sustained improvement of air quality. In addition, this research can advanced our understanding of air pollution in complex terrain. Furthermore, it also promote the construction of the China national strategic Cheng-Yu economic circle and build a beautiful west. Moreover, it provides scientific insights for local policymakers to guide smart urban planning, industrial layout, energy structure, and transportation planning to improve air quality throughout the Cheng-Yu region. Finally, this is also conducive to future scientific research in other regions of China, and even megacities with complex terrain in the world. [ABSTRACT FROM AUTHOR]

This article examines how capital/industrial relocation interacts with work regime dynamics through a case study of geographical relocation of four electronics multinationals from China's coastal regions to its interior. Based on fieldwork conducted in Chongqing and Chengdu between 2012 and 2017, I find that a migrant labor regime in coastal regions has shifted to a local-labor based development strategy in western regions when capital moves inland. This shift, I argue, has increased labor agency and given rise to capital's labor control problems and work regime dynamics that are unique to the relocation process and western China. Specifically, rather than a race-to-the-bottom in labor conditions, three distinct work regimes have emerged in the new sites of production, depending on firms' positions in the global production networks (GPNs) and workers' responses/agency embedded in the GPNs and local labor institutions. They are: (1) advanced quality production and negotiated commitment between workers and management; (2) lean-and-dual and fragmented worker discontent; and (3) flexible Taylorism and high-level worker resistance. The evidence highlights the important role of local state in building location-sensitive labor institutions and workers' constrained, varied agency in influencing work regime dynamics, which challenge many assumptions of the race-to-the-bottom argument associated with capital relocation.

Physically-based landslide susceptibility models have been widely used to predict rainfall-triggered landslides. Calibration of these models is mainly conducted by tuning various inputs, but spatially varying soil properties are not considered. In this study, an efficient probabilistic model calibration method is proposed, which integrates discrete cosine transform (DCT) representation of spatial variability with Bayesian parameter estimation to characterise the spatial variation of soil properties in a physically-based landslide susceptibility model. The efficacy of DCT inversion in representing fields with binary information about landslide occurrence and non-occurrence is investigated. To illustrate the capability and feasibility of the proposed method, a hypothetical example and a case study of a 2014 regional rainfall-triggered landslide event in Qinglian Town, Chongqing, China are presented. The results demonstrate that the location, size and shape of landslide have little influence on the DCT inversion. Considering spatial variation in model calibration can significantly improve model prediction performance for regional rainfall-induced landslides. The topography of the landslide initiation area may affect the influence of the model calibration if the field observations do not agree with the fundamental physics underlying the stability equation used in the model.

The literature on World War II memory in China is skewed toward the history of the occupation and victimization of the eastern provinces. This study shifts the focus to the southwestern city of Chongqing, which served as China's temporary wartime capital and the seat of the CCP–GMD united front. Comparing distinctive thematic narratives of four state museums, this research shows that Chongqing is not an outlier in China's memory scape, as is often presumed. Rather, it finds that these narratives draw selectively and purposefully from local experiences to instantiate and reaffirm the evolving central line. Chongqing's story of unified resistance and joint triumph exemplifies the more inclusive and empowering new norm of war remembrance under Xi Jinping, which stresses national unity as the key to Chinese 'greatness'.

The genetic diversity and population structures of five Chongqing local chicken populations were investigated using by 24 microsatellite markers. Results revealed that the mean number of alleles (NA) ranged from 7.08 (Daninghe chicken, DN) to 8.46 (Nanchuan chicken, NC). The highest observed heterozygosity (HO) and expected heterozygosity (HE) were observed in DN (HO= 0.7252; HE= 0.7409) and the lowest HOand HE were observed in XS (Xiushan native chicken [XS], HO= 0.5910 and HE= 0.6697). The inbreeding coefficient (FIS) within population ranged from 0.022 (DN) to 0.119 (XS). Among the 24 microsatellite markers, four loci (MCW0111, MCW0016, ADL0278, and MCW0104) deviated from the Hardy–Weinberg equilibrium in all the studied populations. The results of population polygenetic analysis based on Nei's genetic distance and STRUCTURE software showed that the clustering of the five populations was incomplete consistent with geographical distribution. Moreover, a large number of gene flows were widespread among different populations, suggesting that genetic material exchanges occurred due to human activities and migration which was also verified by PCoA. In summary, this study preliminarily showed that Chongqing local chicken populations had rich genetic diversity and remarkable genetic divergence, but still high risk in conversion. These findings would be useful to the management of conservation strategies and the utilization of local chicken populations in further. [ABSTRACT FROM AUTHOR]

The city of Chongqing in Southwest China has recently attracted widespread attention for adopting a land-use policy, dipiao, which has radically transformed the rural and urban landscape. Previous research on the impacts of the new scheme on peasants remains inconclusive, which necessitates further qualitative study on whether the policy provides an equitable and sustainable solution to urbanisation. According to the results of semi-structured interviews conducted with 34 relocated peasants, the policy is equitable for all peasants regarding urbanisation. However, economically-disadvantaged peasants struggle with their livelihood after relocation. The findings enrich the understanding of the ongoing urbanisation process in China.

This study investigates the impact and transmission mechanism of foreign direct investment (FDI) inflows on the economic growth of city clusters. Via theoretical analysis, a spatial Durbin model (SDM) and mediating effect model are applied based on panel data of the three major city clusters in the Yangtze River Economic Belt (YREB) from 1997 to 2018. The results reveal the following: (1) FDI inflows promote the economic growth of city clusters in the YREB, but the degrees of impacts on the three city clusters are different; (2) the spatial effects of FDI inflows differ across city clusters; the effects are negative in city clusters of the Yangtze River Delta and the Yangtze River Middle Reaches, and positive in the Chengdu-Chongqing city cluster; (3) urbanization and industrial structure upgrading are two important mechanisms by which FDI inflows promote the economic growth of city clusters. However, there are differences among the three major city clusters; the intermediary effect of urbanization is more significant in city clusters of Chengdu-Chongqing and the Yangtze River Middle Reaches, while the intermediary effect of industrial structure upgrading is more significant in the Yangtze River Delta and Chengdu-Chongqing city clusters. Policy implications are proposed accordingly. [ABSTRACT FROM AUTHOR]

Shunosaurus is a small eusauropod from China. It is characterised by solid cervical and dorsal vertebral centra without complicated pneumatic structures, platycoelous or amphicoelous middle and posterior vertebrae and a lack of pubic foramen in adult individuals. Although many Shunosaurus individuals have been discovered, the ontogenetic characteristics of its long bones and bone tissues are not very clear and the existing description of the postcranial skeleton is relatively rudimentary. The new well-preserved and the smallest Shunosaurus specimen discovered in Yunyang, Chongqing, China, provides good material for solving these problems. The radial distal breadth is more than twice the minimum midshaft breadth, and the fibular distal end is twice as wide as the midshaft, while these ratios are all smaller in adult specimens. The lateral trochanter is undeveloped. This individual does show a pubic foramen. The degree of vascularisation of the bone tissue in the juvenile bone tissue is higher for adults. There are no arrested growth lines and peripheral rest lines in the compact bone, indicating that body size still increases slowly after maturity. The discovery of this new material expands the distribution range of Shunosaurus in China. [ABSTRACT FROM AUTHOR]

China's pilot emission trading schemes (CP-ETS) have been operating for five years since the first pilot ETS launched its carbon market in 2013. The seven pilots have a common framework but different details. In this study, an assessment model which is used to evaluate mitigation efficiency, is constructed by combining the DID method and an evaluation matrix. Results show that the five CP-ETS have been effective in promoting emission reduction, whereas the pilot ETS of Shanghai and Chongqing have failed to drive the covered enterprises to reduce their GHG emission directly. Our findings reveal that at least three key elements, namely, allowance cap, the covered enterprises' potential emission reduction capacity, and economic structure stability, affect the mitigation efficiency of the CP-ETS. The mitigation efficiency of the CP-ETS may be enhanced by conducting a pre-evaluation of the potential mitigation capacity of the covered enterprises, setting a mechanism for the evaluation and adjustment of the allowance cap, and employing financial tools to maintain the carbon price within a reasonable range that most covered enterprises can afford.

Background: Gangliosides (GAs) are important for neuronal function and development of the brain, accumulating rapidly in the fetal brain during the last trimester of pregnancy. No study in humans has investigated whether maternal supplementation of GAs during pregnancy has an effect on fetal growth, particularly of the head circumference.Objective: To evaluate the effect of maternal dietary supplementation of complex milk lipids (CML; gangliosides and phospholipids) from the milk fat globule membrane (MFGM) during pregnancy on fetal growth.Design: Double-blind three-arm parallel randomized controlled trial of 1500 pregnant women from the Chongqing Municipality of China, recruited between 11 and 14 weeks of pregnancy. Intervention was in the form of supplementation with: control maternal milk formulation containing a minimum of 2 mg GA per serving (4 mg GA per day) versus a CML-enriched (CML-E) maternal milk formulation containing a minimum of 4 mg GA per serving (8 mg GA per day) versus no maternal milk supplementation, but with standard obstetric care including prenatal folic acid supplementation. Main outcomes and measures were ultrasonographically-derived estimates of fetal growth in head circumference (HC) & biparietal diameter (BPD) (primary outcomes); and abdominal circumference (AC), femur length (FL) and estimated fetal weight (EFW) (secondary outcomes) (Clinical trial registry: ChiCTR-IOR-16007700).Results: Supplementation with CML-E milk had no effects on size at midpregnancy or growth trajectories in any of the fetal biometric dimensions.Conclusions: Supplementation of CML from the MFGM from the end of the first trimester did not have any effects on fetal growth. The absence of any adverse growth outcomes suggests that maternal MFGM supplementation during pregnancy is safe and using CML-E milk formula can be a method of providing an increased GA and phospholipid supply in early life, which has been associated with neurodevelopmental benefits.Clinical Trial Registry: ChiCTR-IOR-16007700 (http://www.chictr.org.cn/enindex.aspx).

It has long been known that Lower Jurassic theropod track assemblages are dominated by theropod tracks including Eubrontes and Grallator, known from North America since the mid 19th century. It was only comparatively recently that it was recognised that these ichnogenera where also abundant in other regions including China, making them important components of a global Lower Jurassic footprint assemblage zone. Moreover, another theropod ichnogenus, Kayentapus, also proved to be an important component of this assemblage zone in North America, Europe and Asia. The newly reported Kayentapus-occurrences reported here from the Lower Jurassic Geleshan site in Chongqing, China provide some of the best-preserved examples of this ichnogenus in Asia, and show that it can be consistently distinguished from robust Eubrontes. The assemblage is further evidence that the dinosaur tracksites of the Lower Jurassic were theropod dominated in Asia and globally with a consistent diversity of track morphotypes.
