Abstract

Purpose

The practice of renovation and construction of university libraries is flourishing, but how to attract readers to use the library is an issue that urgently needs to be explored. Spatial cognition is a subjective judgment of a person's tendency to take action in the future and implies behavioral intention. Based on the sensory–image–cognition relationship, a theoretical model of university library readers' spatial cognition is conducted, and the influencing factors and mechanisms of spatial cognition are explored based on empirical data to provide theoretical references for spatial practices in university libraries.

Design/methodology/approach

A visual and art-based mental map approach is introduced based on a questionnaire survey. The questionnaire is mainly used for the specific evaluation of spatial use and the breakdown of the detailed elements, while the mental map method is mainly used for the evaluation of readers' spatial cognition. Relevant empirical data are collected from the library of the Zhejiang University of Technology.

Findings

The results indicate that readers' spatial sensory experience and mental imagery have positive effects on readers' behavior via the mediator spatial cognition, readers' spatial sensory experience and mental imagery have a positive effect on readers' spatial cognition and spatial cognition has a significant effect on readers' behavior.

Originality/value

The main contribution of this study is to construct a theoretical model of readers' spatial cognition and to explore the factors that have an impact on spatial cognition and the influence of cognition on behavior. This provides a more rational and in-depth thinking paradigm for the study of university library space and provides theoretical references for library practice.

Abstract

Purpose

The purpose of this paper is to model the aircraft-cargo’s coupling dynamics during ultra-low altitude heavy cargo airdrop and to design the aircraft’s robust flight control law counteracting its aerodynamic coefficients perturbation induced by ground effect and the disturbance from the sliding cargo inside.

Design/methodology/approach

Aircraft-cargo system coupling dynamics model in vertical plane is derived using the Kane method. Trimmed point is calculated when the cargo fixed in the cabin and then the approximate linearized motion equation of the aircraft upon it is derived. The robust stability and robust H optimal disturbance restraint flight control law are designed countering the aircraft’s aerodynamic coefficients perturbation and the disturbance moment, respectively.

Findings

Numerical simulation shows the effectiveness of the proposed control law with elevator deflection as a unique control input.

Practical implications

The model derived and control law designed in the paper can be applied to heavy cargo airdrop integrated design and relevant parameters choice.

Originality/value

The dynamics model derived is closed, namely, the model can be called in numerical simulation free of assuming the values of parachute’s extraction force or cargo’s relative sliding acceleration or velocity as seen in many literatures. The modeling is simplified using Kane method rather than Newton’s laws. The robust control law proposed is effective in guaranteeing the aircraft’s flight stability and disturbance restraint performance in the presence of aerodynamic coefficients perturbation.

Abstract

Purpose

By exploring the impact of digital knowledge resources (DKR) on the carbon emission intensity of the pig industry (PCEI), this study aims to reveal the role of DKR in reducing PCEI.

Design/methodology/approach

Based on provincial panel data in China from 2011 to 2021, this study uses the entropy and Intergovernmental Panel on Climate Change coefficient methods to calculate the evaluation index system of DKR and PCEI, respectively. Empirical analysis using a panel fixed-effects model examines the influence of DKR on PCEI and its underlying mechanisms.

Findings

DKR can significantly reduce PCEI. This conclusion still holds even after undergoing endogeneity treatment and a series of robustness tests. Mechanism test results indicate that DKR can operate indirectly through the mediation mechanism of rural human capital (RHC) and pig breeding technology innovation (PTI), while environmental regulation intensity (ERI) plays a positive moderating role in the relationship between DKR and PCEI. The magnitude of the impact of DKR on PCEI depends on ERI. Further studies found that the impact of DKR on PCEI has obvious heterogeneity characteristics, and the promotion effect is more obvious in regions with good integration degrees and high development potential.

Practical implications

This paper divides DKR into three dimensions: digital technology knowledge (DTK), digital management knowledge (DMK) and digital application knowledge (DAK), providing a new framework for research and enriching the understanding of the relationship between DKR and PCEI. Furthermore, the research results reveal the application potential of DKR in the pig industry, particularly in terms of resource allocation efficiency. This is of great significance for promoting low-carbon development in the pig industry and provides insights for the low-carbon transformation of other industries. In addition, the study emphasizes the moderating effect of ERI on the mechanism of carbon reduction in the pig industry through DKR. This offers a new perspective for understanding the relationship between knowledge management and environmental governance, providing a reference basis for policy formulation in related fields.

Originality/value

This paper further enriches the role of DKR in the livestock industry. Integrating DKR with traditional industries promotes knowledge innovation, information distribution and utilization and scientific decision-making. This has significant value in promoting the development and application of carbon reduction technologies, enhancing industrial competitive advantages, and other aspects.

Abstract

Purpose

This study aims to simulate and test the performance of a transmitting and receiving capacitive micro-machined ultrasonic transducer (CMUT). Aimed at detecting demand of the CMUT, a matched integrated adjustment circuit was designed through analyzing processing methods of transducer’s weak echo signal.

Design/methodology/approach

Based on the analysis of CMUT array structure and work principle, the CMUT units are designed and the dynamic performance analysis of SIMULINK is given according to the demand of underwater detecting. A transceiver isolation circuit is used to make transmission mode and receiving mode separate. A detection circuit is designed based on the transimpedance amplifier to achieve extraction of high-frequency and weak signal.

Findings

Through experimentation, the effectiveness of the CMUT performance simulation and the transceiver integrated adjustment circuit were verified. In addition, the test showed that CMUT with 400 kHz frequency has wider bandwidth and better dynamic characteristics than other similar transducers.

Originality/value

This paper provides a theoretical basis and design reference for the development and application of CMUT technology.

Abstract

Purpose

This study aimed to investigate associations between the organisational and cultural contexts in which Chinese teachers work, the influence of these on their understandings of professionalism, and relationships between these and their perceived willingness and commitment to be effective in teaching to their best.

Design/methodology/approach

The research was part of a two-country collaboration between the universities of Beijing and Sydney into Australian and Chinese teachers' perceptions of influences on their professionalism in which research protocols were jointly developed and implemented. This paper focusses mainly upon the Chinese research but also refers to key differences between Australian and Chinese teachers' perspectives. Seventeen teachers in early, middle and later career phases were recruited from a convenience sample of primary and secondary schools in Beijing. Qualitative data analyses of individual interviews, and cross case comparative analyses were conducted.

Findings

The analyses of the data from Beijing indicated that almost all teachers emphasised their strong moral purposes and commitment to teach to their best, despite identifying the challenges of workload, school contexts and cultures and personal circumstances, which tested their resolve. In contrast, concerns about teacher autonomy and agency, which were common in the Australian study and other published research literature, were not highly visible in the Chinese data.

Research limitations/implications

The authors acknowledge that this study was small scale and data were collected from a narrow sample from one urban region of China, and we should be cautious with the generalisability of findings to other regions and schools of China since there are significant discrepancies between developed coastal areas and large cities and the remote rural areas in China. Furthermore, interview data were only collected once, restricting insight to a snapshot in time. This research may be seen as an encouragement to researchers from other regions and countries to further explore the impact of socially situated understandings of teacher professionalism on practice. Future research could also benefit from utilising multiple data sources, longitudinal design and cross-cultural collaborations to further explore the challenge of defining teachers' understandings of professionalism locally while engaging with global perspectives.

Practical implications

The practical implications relate to (1) expanding conceptualisations of teacher professionalism by developing locally nuanced understandings of perceptions and enactments of professionalism in different contexts across the profession, which take account of the unique roles of national and local cultural contexts; (2) designing initial teacher education and continuing professional development programmes so that they take account of the influences on the professions' ideals and individual teacher identities, of the ideological and practical interplay in the workplace of structures such as mandated standards, and different socio-economic geographical settings (e.g. rural and urban); (3) designing leadership development programmes that take account of research on associations between school leaders' values, qualities and practices on school cultures and their effects on teachers' well-being, and capacities and capabilities to fulfil their understandings of being professionals and teach to their best.

Social implications

The social implications relate to (1) further research on the associations between the effects of external policy demands on teachers' work and work–life tensions, teachers' sustained commitment and quality; and (2) further research on the impact of the collective influences of national cultures, broad-based policy conditions, personal values and the demands of particular schools, parents and students that influence teachers' experience, perceptions and enactments of professionalism in order to provide further insights into understanding the complexity of teachers' lives and promoting teachers' sustained enactments of professionalism in broad contexts.

Originality/value

The research findings, though tentative, revealed that the altruistic nature of their mission to serve students and the parental community was the dominant marker of professionalism for teachers in China, regardless of school structures, cultures, academic achievement imperatives and personal circumstance; and that their professionalism was informed by the socio-cultural formation of individual and collective moral responsibility, reinforced through national educational policies. These findings differed from the concerns reported by the teachers in the Australian study, which aligned with literature that suggests that teacher professionalism is being eroded through neo-liberal government policies, excessive workloads and performance-oriented cultures. Though the comparative data set is small, these findings suggest that whilst there are increasing policy convergences across nations, which seek to define teacher professionalism through their abilities to make improvements in students' measurable academic achievement, how teachers in different countries and cultures define themselves as professionals may differ.

Abstract

Purpose

The purpose of this paper is to provide a modified welding image feature extraction algorithm for rotating arc narrow gap metal active-gas welding (MAG) welding, which is significant for improving the accuracy and reliability of the welding process.

Design/methodology/approach

An infrared charge-coupled device (CCD) camera was utilized to obtain the welding image by passive vision. The left/right arc position was used as a triggering signal to capture the image when the arc is approaching left/right sidewall. Comparing with the conventional method, the authors’ sidewall detection method reduces the interference from arc; the median filter removes the welding spatter; and the size of the arc area was verified to reduce the reflection from welding pool. In addition, the frame loss was also considered in the authors’ method.

Findings

The modified welding image feature extraction method improves the accuracy and reliability of sidewall edge and arc position detection.

Practical implications

The algorithm can be applied to welding seam tracking and penetration control in rotating or swing arc narrow gap welding.

Originality/value

The modified welding image feature extraction method is robust to typical interference and, thus, can improve the accuracy and reliability of the detection of sidewall edge and arc position.

Abstract

Purpose

The construction industry has been investigating “where Henry Ford is in the industry system.” Given that listed construction enterprises are the backbone of the promotion of the high-quality development of the industry, their research and innovation are of considerable importance. This study aims to comprehensively assess the research and development (R&D) status quo and trends within various types of construction enterprises in order to identify effective strategies to enhance R&D efficiency in the construction industry.

Design/methodology/approach

Based on the data won from annual reports and the CSMAR database for the period 2016–2020, this study examines 104 listed construction enterprises in China. By applying both the data envelopment analysis (DEA) method and the Malmquist productivity index, this research compares and analyzes the static and dynamic differences in R&D efficiency across different types of construction enterprises.

Findings

Results suggest that the magnitude of change in the Malmquist decomposition index of 104 listed construction enterprises gradually narrowed, but the comprehensive technological level remained relatively low. Although state-owned enterprises had an advantage in scale efficiency, meaning they could maximize output with given inputs, their technological progress efficiency, also known as the degree of technological innovation, was significantly lower than that of private enterprises. As one finding, state-owned enterprises in comparison with private enterprises experience significant R&D inefficiency. It represents the main cause of their low degree of technological innovation and efficiency.

Originality/value

This study assesses the R&D efficiency of listed construction enterprises in China from the perspective of different market segments, state-owned and private enterprises and suggests approaches to improve strategies for various corporate types. Thus, the study’s new findings contribute to addressing the challenge of low R&D levels in the construction industry in the fields of engineering, construction and architectural management.
