Abstract

Along with the acceleration of Chinese urbanization, urban history degrades at a rapid rate, and development follows formalism. Based on architectural typology, this study introduces a methodology of concept mapping and discusses the urban complex design method from a perspective of regional cultural elements. The theoretical analysis shows that concept mapping represents an integrated solution that incorporates regional cultural elements into architectural planning. Through the concept mapping method, it not only protects the physical environment, but also strengthens modern urban residents’ psychological sense of belonging to their own living space. Meanwhile, distinct regional cultural elements can be efficiently combined in the overall layout, monomer building design, building details design, and landscape design of urban complex by using different architectural design methods. This design method is validated using an actual case in Guizhou. Therefore, it forms a complete set of design method with a three-step framework, namely positioning cultural areas, summarizing regional cultural elements, and selecting the mapping method and combination mode.

Abstract

Purpose

This study aims to investigate how long commutes negatively affect employees’ creative deviance at work, exploring the mediating role that impaired work–life balance plays in linking commute to restricted creative deviance, as well as examining whether access to flexible work arrangements can alleviate commuting’s detrimental indirect effects.

Design/methodology/approach

This study employed a three-wave survey methodology conducted over monthly intervals with 246 participants in China’s Pearl River Delta region. Rigorous screening ensured a demographically diverse sample.

Findings

Commuting time negatively affects creative deviance, both directly and indirectly through work–life balance. Flexible work arrangements mitigate the adverse effects of long commutes on work–life balance, subsequently weakening the indirect effect of commuting time on creative deviance through work–life balance.

Practical implications

A holistic approach is suggested for organizations aiming to foster a supportive and ethical work environment, which involves a combination of organizational policies, leadership practices and individual actions to promote both creativity and employee welfare.

Originality/value

This research breaks new ground by identifying commuting time as a key factor influencing creative deviance in the workplace, mediated by work–life balance. It integrates transportation research with organizational behavior, applying an ethics of care perspective to challenge traditional paradigms. The study’s interdisciplinary approach, bridging multiple fields, provides a novel, holistic view of how non-work factors impact workplace innovation.

Abstract

Significant differences exist in terms of use and demand of urban public space in different districts and communities. In this study, PSPL survey was made in about one year to investigate the type and occurring time of outdoor activities and the visitors' demand difference of Round-City-Park in Xi'an, China. The survey method for collecting data included spatial classification, photographic recording, field observation, questionnaires and interviews. Then a new method of Virtual Typical Day (VTD) was put forward to analyze usage pattern of public space in the daily life. According to our results, laying out more public spaces close to residential area can make a more vigorous city. And the results also reveal that there exist some problems of uneven usage periods in different spaces, various space requirement from different age groups, insufficient support of space and facilities and so on. Based on the survey, an optimizing strategy of adaptive design is proposed such as setting mobile “stage” and providing flexible “props” according to the changing demands. The proposed design approach can encourage people to participate in outdoor activities, improve usage frequency of public spaces, and stimulate vitality of the city. This may also apply to other Chinese cities.

Abstract

Purpose

Thruster point assembly mechanism (TPAM) of the electric propulsion system allows to adjust the thrust vector, so that the thrust vector is directed to the satellite center of gravity (COG) during the satellite on-orbit working period. In this way the impact of disturbance torque caused by deviation of the thrust vector from the satellite COG during thruster ignition can be decreased. Therefore, the control accuracy of satellite is influenced directly by the control accuracy of TPAM. On the other hand, the on-orbit application of TPAM is restricted to the on-orbit computer resource. Therefore, the purpose of this paper is to design a control strategy for TPAM, and the strategy should not only be able to control the TPAM precisely but also be easily implemented by the on-board computer.

Design/methodology/approach

First, the structure and work principle of TPAM are discussed, and the mathematical model based on D-H coordinate system is built for it. Then the fitting methods are utilized to design the control strategy of TPAM. Absolute position fitting-based control strategy and relative position fitting-based control strategy are designed, and the least squares algorithm is introduced for parameter selection.

Findings

Simulations and tests are provided for the TPAM. Compared with the state-of-the-art PD controller, the proposed control strategy shows smaller overshoot and more simple realization. The experiment results are matched with the simulation results and both the experiment and simulation results show the validity of the proposed control strategies.

Practical implications

The designed control strategies can be used for the TPAM of some satellite’s electric propulsion system.

Originality/value

The mathematical model of the TPAM based on D-H coordinate system is given. The absolute position fitting-based control strategy and relative position fitting-based control strategy are proposed. Compared with existing methods, the two control strategies have more simple structure and smaller amount of computations. Furthermore, the relative position fitting-based control strategy achieves high precision with simple structure.

Abstract

Purpose

This paper aims to document and to illustrate highly usable research: a practical framework for realizing the sustainable operations of the high investment, technology-intensive high-speed railways in China. Also, for the first time, we draw a broad, metaphorical relationship between railways within a country to Chinese meridian lines within a human body. These are similar in enabling flows across the country and human body.

Design/methodology/approach

Employing Chinese case studies, we attempt to apply methodological procedures involving operational, financial and developmental in realizing the sustainability of high-speed railways. Critical criteria are emphasized for efficiency, financial viability and long-term funding sustained development of high-speed railways in the Chinese context. Policymakers may utilize the illustrative framework in working toward specific recommendations that may be implementable.

Findings

Three critical aspects to sustainability are operational, financial solvency and developmental. Our empirical investigations result in the working out of the procedural aspects as well. Based on this three-way classification, we design an evaluative framework for realizing sustainability of high-speed railways. Our insights are based on the social reality of China. Thus, we argue that cash handouts by government are necessary solutions, given the intensive capital investments required of high-speed railways for strongly positive externalities generated. On developmental aspects of sustainability, there should be rational, in-depth studies conducted so as to lead to rational choices of sites. Strong passenger flows coupled with affordability of fares are the twin guarantees of continuing, profitable performances.

Practical implications

This work on sustainability is globally, most highly significant for two reasons. First, railway is one fundamental mean of transportation within China. Thus, the sustainability of railway matters to a majority of the 1.3 billion people. Second, transport volume of China’s railway is the world’s largest. By developing such a comprehensive methodology, we hope to enhance how top management of Chinese Railways may keep the high-speed railways sustainable into the future.

Social implications

This paper is socially highly significant, especially in the context of what has happened in recent years in China’s railway industry, and may contribute by providing both the regulators and management with an objective methodology in future projects assessment within high-speed railway.

Originality/value

This paper develops an overall framework for enabling management to realize sustainability of high-speed railway within China. The ideas, concepts and methodologies are likely beneficial to top management, regulators and policymakers within the railway transportation, a state monopoly.

Abstract

Purpose

The purpose of this study is to characterize the galvanic corrosion behavior of a simulated X80 pipeline steel welded joint (PSWJ) reconstructed by the wire beam electrode (WBE) and numerical simulation methods.

Design/methodology/approach

The galvanic corrosion of an X80 PSWJ was studied using WBE and numerical simulation methods. The microstructures of the coarse-grained heat affected zone, fine-grained heat affected zone and intercritical heat affected zone were simulated in X80 pipeline steel via Gleeble thermomechanical simulation processing.

Findings

Comparing the corrosion current density of coupled and isolated weld metal (WM), base metal (BM) and heat-affected zone (HAZ), the coupled WM exhibited a higher corrosion current density than isolated WM; the coupled BM and HAZ exhibited lower corrosion current densities than isolated BM and HAZ. The results exhibited that the maximum anodic galvanic current fitted the Gumbel distribution. Moreover, the numerical simulation results agreed well with the experimental data.

Originality/value

This study provides insight into corrosion evaluation of heterogeneous welded joints by a combination of experiment and simulation. The method of reconstruction of the welded joint has been proven to be a feasible approach for studying the corrosion behavior of the X80 PSWJ with high spatial resolution.

Abstract

Purpose

The emergence of mobile health (mHealth) products has created a capability of monitoring and managing the health of patients with chronic diseases. These mHealth technologies would not be beneficial unless they are adopted and used by their target users. This study identifies key factors affecting the usage of mHealth apps based on user usage data collected from an mHealth app.

Design/methodology/approach

Using a dataset collected from an mHealth app named mPower, developed for patients with Parkinson's disease (PD), this paper investigated the effects of disease diagnosis, disease progression and mHealth app difficulty level on app usage, while controlling for user information. App usage is measured by five different activity counts of the app.

Findings

The results across five measures of mHealth app usage vary slightly. On average, previous professional diagnosis and high user performance scores encourage user participation and engagement, while disease progression hinders app usage.

Research limitations/implications

The findings potentially provide insights into better design and promotion of mHealth products and improve the capability of health management of patients with chronic diseases.

Originality/value

Studies on the mHealth app usage are critical but sparse because large-scale and reliable mHealth app usage data are limited. Unlike earlier works based solely on survey data, this research used a large user usage data collected from an mHealth app to study key factors affecting app usage. The methods presented in this study can serve as a pioneering work for the design and promotion of mHealth technologies.

Abstract

Purpose

As a frequently observed business phenomenon, the use of product scarcity to improve a product’s market performance has received increasing attention from both academics and practitioners. The resulting literature has covered a wide variety of issues based on various theories, using different research methods, in a diverse range of settings. However, this diversity also makes it difficult to grasp the core themes and findings, and to see the outstanding knowledge gaps. This paper aims to review previous studies on the use of product scarcity in marketing and identifies new directions for future research.

Design/methodology/approach

A systematic review was conducted to identify and analyse 66 research papers published in business and management journals between 1970 and 2017.

Findings

The authors examined the underlying theories of scarcity-based marketing, and developed a conceptual framework that describes the key factors of product scarcity and how they influence both consumers and the market. They also highlighted some key achievements in modelling the processes involved in using product scarcity in marketing.

Originality/value

This analysis of the identified papers suggests that there are substantial gaps in our knowledge of this field, which opens up new paths for future research. For future research, the authors identified three directions aimed at: addressing the practical needs of firms in understanding product scarcity; guiding the implementation of scarcity-based strategies; and measuring, monitoring and predicting the level of product scarcity and its impacts during implementation.

This paper aims to use redundant manipulators to solve the challenge of collision avoidance in construction operations such as welding and painting.

Abstract

Purpose

This paper aims to use redundant manipulators to solve the challenge of collision avoidance in construction operations such as welding and painting.

Design/methodology/approach

In this paper, a null-space-based task-priority adjustment approach is developed to avoid collisions. The method establishes the relative position of the obstacle and the robot arm by defining the “link space,” and then the priority of the collision avoidance task and the end-effector task is adjusted according to the relative position by introducing the null space task conversion factors.

Findings

Numerical simulations demonstrate that the proposed method can realize collision-free maneuvers for redundant manipulators and guarantee the tracking precision of the end-effector task. The experimental results show that the method can avoid dynamic obstacles in redundant manipulator welding tasks.

Originality/value

A new formula for task priority adjustment for collision avoidance of redundant manipulators is proposed, and the original task tracking accuracy is guaranteed under the premise of safety.
