With the rapid development of modern economy and the process of urbanization is faster, a large number of historical relics have been mercilessly destroyed in the urban reconstruction. In order to balance the contradiction between urban development and historical heritage and promote the harmonious development of new and old urban areas, it is necessary to research on the old urban areas from the perspective of historical landscape. Old urban area of Jingdezhen is taken as an example in this paper, the present situation of the reconstruction of the old city in Jingdezhen is analyzed. Then, by using the methodology of urban historical landscape, some specific methods for updating and designing the old urban area reconstruction of Jingdezhen is put forward, such as the elements of spatial form, urban texture, historical and cultural landscape elements, streets and alleys, the Changjiang River, public facilities and landscape sketches, and so on. A new design method of landscape transformation of old urban area is established. As the renewal method of respecting the urban history and cultural heritage is a very intelligent urban renewal model, it is found that the application of urban historical landscape in the old urban city is reasonable and effective, which is based on the development of the old urban area and pursues the coexistence of protection and development.

The purpose of this paper is to present a weakly supervised learning method to perform health evaluation and predict the remaining useful life (RUL) of rolling bearings.

Based on the principle that bearing health degrades with the increase of service time, a weak label qualitative pairing comparison dataset for bearing health is extracted from the original time series monitoring data of bearing. A bearing health indicator (HI) quantitative evaluation model is obtained by training the delicately designed neural network structure with bearing qualitative comparison data between different health statuses. The remaining useful life is then predicted using the bearing health evaluation model and the degradation tolerance threshold. To validate the feasibility, efficiency and superiority of the proposed method, comparison experiments are designed and carried out on a widely used bearing dataset.

The method achieves the transformation of bearing health from qualitative comparison to quantitative evaluation via a learning algorithm, which is promising in industrial equipment health evaluation and prediction.

Like other nations in Asia, mainland China has undergone continuous reforms in its economic, political and social institutions over the past two decades. These changes are also reflected in its education system, which has been both the target of government reforms and an agent for social change. In this context, China's Ministry of Education has cast school principals as key actors in leading and managing change in schools at the local level throughout the country. The purpose of this paper is to explore how Chinese school leaders successfully respond to the implementation of educational reform.

In this paper the authors explore how school leaders in one city in South China perceive their roles and actions in fostering successful change. The study employed extensive literature review with qualitative interviews of five school principals who had demonstrated success at leading change in their schools.

The findings of both the literature review and interview study unexpectedly found more similarities than differences between how leaders contribute to successful change in China as compared with the Western literature.

The research findings are limited by two main features. First, the sources analyzed in the literature review were of highly varying quality. Moreover, relatively few employed replicable analytical methods capable of generalization. These limitations of the literature mean that the results of the review can only be interpreted as suggestive rather than conclusive. Second, the interview study was framed as an effort to further explore the trends of the literature review. Although the findings from the small-scale interview study were consistent with the broader Chinese literature, the research design suffers form the same limitations as the general literature. Therefore, these findings must also be treated as emergent rather than explanatory.

The paper identifies directions for future research and discusses implications for school leaders in implementing educational change in China.

The originality of this study lies in its attempt to synthesize a previously inaccessible literature on change leadership in Chinese schools. Despite China's rising role as a global leader, the literature in educational leadership and management remains sparse and largely unknown to Western scholars. Therefore, the study's limitations are balanced by the need to provide better descriptions of current practices employed by leaders as they attempt to improve China's schools.

An increasing number of Chinese enterprises are involved in cross-border mergers and acquisitions (M&As). However, few Chinese enterprises have achieved successful integration, which plays a critical role in enhancing performance. The important field of cultural integration is currently facing major challenges. To identify the reasons for these challenges, studies have analyzed why cultural integration succeeds or fails and have suggested that cultural differences between acquiring and acquired enterprises are the primary obstacles to cultural integration. However, it is unclear how success can be achieved. The paper aims to focus on cultural integration from the perspective of acculturation to describe the penetration of cultural elements in M&As.

In adopting acculturation as our theoretical lens, the authors use the case study method to answer the following research question: “how can the cultural integration of Chinese enterprises be successfully achieved?” Two typical cases are examined: Lenovo’s cultural integration with IBM’s personal computer (PC) division and Haier’s cultural integration with Sanyo home appliance. First, using the exploratory case study method, the Lenovo–IBM PC division case is analyzed. The characteristics and relationships between cultural environments, employee adoption methods and acculturation patterns are summarized to reveal a cultural integration path. Second, the Haier–Sanyo home appliance case is analyzed using the confirmative case study method to test the findings of the Lenovo–IBM PC division case.

The results indicate that it is critical to achieve a dynamic fit between cultural environments, employee adoption methods and acculturation patterns during each stage of cultural integration (exploration, experimentation, reinforcement and fixing). The three constructs of these stages reflect the following evolutionary paths: “isolate-introduce-learning-chance taking”, “detecting-icebreaking-interacting-remodeling” and “specialized sections-senior managers-managers-employees”.

These findings contribute to the development of cultural integration and acculturation theories and serve as a reference for Chinese enterprises wishing to implement cultural integration strategies.

This paper aims to present a novel position sensorless control scheme with fault-tolerance ability for switched reluctance motor at low speed.

First, the detection pulses are injected in the freewheeling and idle intervals of each phase. Second, the aligned position of each phase can be detected by comparing the consecutive rise time of detection current. Third, the whole-region rotor position and real-time rotational speed can be updated four times for the improvement of detection accuracy. Finally, the fault-tolerant control strategy is performed to enhance the robustness and reliability of proposed sensorless scheme under faulty conditions.

Based on proposed sensorless control strategy, the estimated rotor position is in good agreement with the actual rotor position and the maximum rotor position error is 1.5°. Meanwhile, the proposed sensorless scheme is still effective when the motor with multiphase loss and the maximum rotor position error is 1.9°. Moreover, the accuracy of the rotor position estimation can be ensured even if the motor is in an accelerated state or decelerated state.

The proposed sensorless method does not require extensive memory, complicated computation and prior knowledge of the electromagnetic properties of the motor, which is easy to implement. Furthermore, it is suitable for different control strategies at low speed without negative torque generation.

This paper examines the impact and mechanism of China's digital inclusive finance on rural consumption upgrade. First, the impact of the development of digital inclusive finance on the upgrading of rural household consumption structure is to be theoretically analyzed and empirically tested. Secondly, in terms of heterogeneity analysis, it pays attention to the age heterogeneity of users that digital inclusive finance influencing rural residents' developmental consumption upgrade, which is related to the issue of intergenerational “digital gap”. Thirdly, the mechanism of digital inclusive finance in promoting rural consumption upgrade is to be investigated. Finally, how to promote the role of digital inclusive finance in upgrading the structure of rural consumption to a developmental demand level will be showed.

From the perspective of the micro-household, this study is conducted by using the instrumental variable (IV) method, with 2SLS model and IV-Tobit model, based on the matched city-level data of Digital Inclusive Financial Index (DIFI) with the Chinese Household Financial Survey (CHFS). “The relief degree of land surface” is an ideal instrumental variable of digital inclusive finance, for including regional altitude difference and terrain factors of regional area, has theoretical influence on the development of digital inclusive finance, and is not affected by other economic variables.

The conclusions show that the digital inclusive finance plays a significant role in promoting the rural households' developmental consumption, but has no significant effect on the rural households' survival-type consumption and hedonistic consumption. Furthermore, this paper examines the impact and mechanism of China's digital inclusive finance on rural consumption upgrade. First, the impact of the development of digital inclusive finance on the upgrading of rural household consumption structure is to be theoretically analyzed and empirically tested. Secondly, it is discovered that digital inclusive finance is age heterogeneous in promoting the upgrade of consumption structure of rural household, and its effect on the elderly is weaker than that on the young for the intergenerational “digital gap”. Thirdly, these conclusions reveal that the digital inclusive finance does affect the consumption of rural residents through three mechanisms: increasing income and wealth, easing liquidity constraints and facilitating payment methods. Finally, how to promote the role of digital inclusive finance in upgrading the structure of rural consumption to a developmental demand level will be showed.

The current research on the relationship between digital inclusive finance and rural consumption only stays at the level of total rural consumption and has not stressed the structural problems of rural consumption. Can digital inclusive finance promote the upgrade of rural consumption structure? To what level can digital inclusive finance promote the upgrading of rural consumption structure? Therefore, it is of great theoretical value to study the upgrading of rural consumption structure from the micro level. Can the current digital inclusive finance benefit the elderly and help break the vulnerability of the elderly to enjoy finance? In this regard, evidence of heterogeneity remains to be provided.

Electrical capacitance tomography (ECT) and electrical resistance tomography (ERT) are promising techniques for multiphase flow measurement due to their high speed, low cost, non-invasive and visualization features. There are two major difficulties in image reconstruction for ECT and ERT: the “soft-field”effect, and the ill-posedness of the inverse problem, which includes two problems: under-determined problem and the solution is not stable, i.e. is very sensitive to measurement errors and noise. This paper aims to summarize and evaluate various reconstruction algorithms which have been studied and developed in the word for many years and to provide reference for further research and application.

In the past 10 years, various image reconstruction algorithms have been developed to deal with these problems, including in the field of industrial multi-phase flow measurement and biological medical diagnosis.

This paper reviews existing image reconstruction algorithms and the new algorithms proposed by the authors for electrical capacitance tomography and electrical resistance tomography in multi-phase flow measurement and biological medical diagnosis.

The authors systematically summarize and evaluate various reconstruction algorithms which have been studied and developed in the word for many years and to provide valuable reference for practical applications.

To explore the economical and reasonable semi-rigid permeable base layer ratio, solve the problems caused by rainwater washing over the pavement base layer on the slope, improve its drainage function, improve the water stability and service life of the roadbed pavement and promote the application of semi-rigid permeable base layer materials in the construction of asphalt pavement in cold regions.

In this study, three semi-rigid base course materials were designed, the mechanical strength and drainage properties were tested and the effect and correlation of air voids on their performance indexes were analyzed.

It was found that increasing the cement content increased the strength but reduced the air voids and water permeability coefficient. The permeability performance of the sandless material was superior to the dense; the performance of the two sandless materials was basically the same when the cement content was 7%. Overall, the skeleton void (sand-containing) type gradation between the sandless and dense types is more suitable as permeable semi-rigid base material; its gradation is relatively continuous, with cement content? 4.5%, strength? 1.5 MPa, water permeability coefficient? 0.8 cm/s and voids of 18–20%.

The study of permeable semi-rigid base material with large air voids could help to solve the problems of water damage and freeze-thaw damage of the base layer of asphalt pavements in cold regions and ensure the comfort and durability of asphalt pavements while having good economic and social benefits.

The purpose of this paper is to examine the influence of clan social capital on the willingness to pay (WTP) and WTP value for collective biogas investment.

Using the Heckman two-stage model and a dataset of 1,265 representative observations from three provinces in Central China collected in 2019, this paper utilizes the contingent valuation method to estimate households' WTP value for collective biogas investment. The paper also explores the heterogeneity between households with different clan governance mechanisms and village governance structures.

The results indicate that clan networks and trust were likely to improve farmer households' WTP, while clan trust and norms could improve their WTP values. For clans with councils and for clans that can influence the decision-making of village committees, their members were more likely to be influenced by the social capital of their clans to pay for collective biogas investment.

This paper focuses on the WTP and WTP values of households for collective biogas investment, which is often neglected in the research. This paper suggests that clans can be used as a medium to urge households to increase their collective power to reduce carbon emissions and climate crises. The findings empirically contribute to efforts to reduce rural carbon emissions.

Current policies and research on carbon emissions focus on operational emission but overlook the importance of embodied and user-transport emissions in residential buildings. This study built a comprehensive framework to assess the impact of life-cycle carbon emissions on different in-building open public spaces (open roof, open vertical garden, and open ground floor) in affordable housing.

A parametric model of a typical affordable housing building in Shanghai, China was constructed and 36 variations of open public spaces studied. Embodied, operational, and user-transport carbon emissions were quantified over 50 years.

The results show that the life-cycle carbon emissions decrease with the application of the open public space. In addition, the paper found that the carbon reduction due to user transport is seven times higher than the carbon increment due to construction and over long-term operation.

This paper provides quantitative evidence for carbon emissions and in-building open public spaces, and the authors suggest taking multiple aspects into account in addition to the structure of the building is crucial to sustainable building development.
