With the increase of motor vehicles, ambient air pollution related to traffic exhaust has become an important environmental issue in China. Because their fast growth and development, children are more susceptible exposure. Many chemicals from exhaust, such as carbon monoxide, nitrogen dioxide, lead, have been reported show adverse effects on neurobehavioral functions. Several studies China suggested that might affect functions adults who occupational However, few data function children.The...

This research examined the relationships between students' academic performance and their social emotional skills in China, as well mediation pathways from perspective of connectedness cognitive theory. A sample 5,703 fourth to sixth graders less affluent areas was investigated a large-scale survey. The results indicated that had salient positive connections with socio-emotional skills. Structural equation modeling revealed both perception themselves (self-efficacy) relation key persons...

Modulated signal recognition and classification occupies an important position in electronic information warfare, intelligent wireless communication, fast modulation demodulation. To address the shortcomings of existing methods, such as high manual involvement, few types, a low rate under signal-to-noise ratio, we propose attention mechanism short-link convolution long short-term memory deep neural networks (ASCLDNN) model. The network is optimized for modulated incorporates to achieve...

In this study, a general type-2 fractional order fuzzy PID (GT2FO-FPID) controller is proposed to fulfil the balance adjustment of Power-line Inspection (PLI) robot system. It combination Mamdani logic (GT2-FLC) and controller. Since PLI system an under-actuated system, it’s necessary get complete information However, when all state variables are treated as input controller, there problem with rule explosion. Because this, fusion method adopt solve simplify design. At same time,...

To address the shortcomings of existing methods such as low recognition accuracy and poor anti-interference performance under signal-to-noise ratios, this paper proposes RFSE-ResNeXt (Residual-fusion squeeze–excitation aggregated residual for networks, RFSE-ResNeXt) network. In paper, we improve structure network based on ResNeXt then introduce compressed excitation to generalization ability The improvement leads a good in overall network; meanwhile, improves confusion phenomenon when faces...

<p style='text-indent:20px;'>A control parametrization based optimal PID tuning scheme for a single-link manipulator is developed in this paper. The performance specifications of the system are formulated as continuous state inequality constraints. Then, problem can be an parameter selection subject to These constraints handled by constraint transcription method together with local smoothing technique. In such way, transformed becomes canonical form, which solved efficiently method. Since...

This study analyzes the structural reform of local governments funding for early childhood education (ECE) as general public still casts doubts about fairness ECE system in China. A particular case point is Shenzhen Municipal Government's on their system. Because efforts are more restructuring social welfare than redistributing resources, need to properly define governmental responsibilities before attempting resolve issue. After initial trials and errors, such reforms move toward a...

IN 2010, CHINA'S GOVERNMENT announced that by 2020 all kindergarten-aged children will be able to gain access at least a one-year, high-quality kindergarten experience. This announcement reflected the state's acceptance formal experience can assist become learners China need as it transitions knowledge economy, government's wish reduce social inequality and increasing proportion of families do not have grandparents who help care for young children. The aim this research was investigate...

This paper is about an experiment in non-formal early childhood education for migrant children Beijing. The Si Huan Playgroup was set up by a group of volunteers 2004 and built on ideas pedagogy, equity, life-long learning education. Non-formal has implications policy makers as this model that the potential to build capacity disadvantaged communities provide educational experiences preschool children. model, envisaged participants Playgroup, provider education, operates volunteer basis aims...

Gender disparity in education is a perpetually compelling issue. It especially attention-grabbing economically disadvantaged areas, as it may reinforce backwardness on top of economic vulnerability. Underpinned by the self-determination theory, this study examined underlying mechanisms that gave rise to gender differences academic achievement upper primary grades students from areas China. We drew dataset 5,032 four through six, assembled 89 schools three counties spanning two provinces. The...

ISEE-0914 Objectives: The objective of this study was to explore the association between traffic-related air pollution exposure and its impacts children’s neurobehavioral functions. Methods: A field conducted in Quanzhou, China where two primary schools were chosen based on traffic density monitoring data ambient pollutants. School located polluted area B clear area. Nitrogen dioxide (NO2) PM10 at campus classroom monitored as indicators for pollution. battery manual computerized testing...

Abstract China's government has abolished its one‐child policy and intends to universalise access preschool education by 2020. It also announced plans raise the retirement age beginning in 2022. Together, these policies risk generating a major increase number of parents who must balance workplace–preschool demands with little assistance from grandparents. Drawing on mixed‐method design sample parent‐workers reside Beijing, this article finds that most currently deem need reconcile respective...
