Abstract
Purpose
The purpose of this paper is to understand the natural wind field characteristics of the tunnel entrance section and analyzing the aerodynamic performance of high-speed railway trains (HSRTs) under natural winds.
Design/methodology/approach
Three typical tunnel entrance section sites, namely, tunnel–bridge in a dry canyon (TBDC), tunnel–bridge in a river canyon (TBRC) and tunnel–flat ground (TF), are selected to conduct a continuous wind field measurement. Based on the measured wind characteristics, the natural winds of the TBDC and TF sites are reconstituted and imported into the two corresponding full-scale computational fluid dynamics models. The aerodynamic loads of the HSRT running on TBDC and TF with reconstituted winds are simply analyzed.
Findings
The von Kármán spectrum can be used to describe the wind field at the tunnel entrance section. In the reconstituted natural wind condition, a time-varying feature of wind speed distribution and leeward side vortex around the HSRT caused by the wind speed fluctuation is found. The fluctuating amplitude of aerodynamic loads at the TBDC infrastructure is up to 97.9% larger than that at the TF infrastructure.
Originality/value
The natural wind characteristics at tunnel entrance sections on the high-speed railway are first measured and analyzed. A numerical reconstitution scheme considering the temporal and spatial variation of natural wind speed is proposed and verified based on field measurement results. The aerodynamic performance of an HSRT under reconstituted natural winds is first investigated.

Abstract
Purpose
The purpose of this study is to investigate the impact of board secretaries’ characteristics on annual report readability using an original method that evaluates the readability of Chinese characters.
Design/methodology/approach
The authors manually collect board secretaries’ characteristics from the China Securities Market and Accounting Research database and obtain annual reports from the China Information website. Ordinary least square regression is applied to evaluate the impact, and then robustness tests and additional regression analyses are conducted.
Findings
Board secretaries’ legal-professional expertise, international expertise and role duality improve annual report readability. However, their political connections are negatively associated with it. The effect of expertise (role duality) is more pronounced for firms with lower ex ante litigation risk (board secretaries with equity holdings). Furthermore, higher readability increases the compensation of board secretaries, whereas lower readability increases their turnover. Finally, annual report readability is positively related to firm performance.
Research limitations/implications
The authors only investigate listed firms in China from 2007 to 2017 because of the difficulties of obtaining data and text mining.
Practical implications
The authors provide managerial insights for regulators aiming to establish an effective governance mechanism with Chinese characteristics. First, certain requirements for board secretaries’ expertise can improve annual report readability. Further, firms can consider appointing board members or senior executives as board secretaries to enhance disclosure quality.
Originality/value
To the best of the authors’ knowledge, this study is the first to verify the effect of board secretaries’ characteristics on disclosure quality, especially annual report readability. Moreover, this study proposes a novel measure of annual report readability for Chinese texts.

Abstract
Purpose
To offer a realistic foundation for urban cultural construction planning, we want to investigate the distribution features of Shanghai's cultural functional elements and examine the distribution patterns in urban space.
Design/methodology/approach
In this research, we managed to gather POI geographic data, refined and categorized them to integrate eight categories of cultural functional elements, observed the density and agglomeration, distribution direction and hot and cold spots of overall and each type of cultural functional elements using geospatial analysis methods and then investigated the factors influencing cultural functional elements using geographic detectors.
Findings
Our research shows apparent differences between regions and most cultural functional elements are found in the inner city. Second, there are hot and cold spots in the way different cultural functional elements are spread out. Its geographic structure is primarily influenced by third-party traffic service capacity and available time.
Originality/value
This work provides a benchmark for cultural planning in Shanghai by establishing the spatial aggregation impact of cultural functional elements.

Abstract
Mobile agent, as a new mobile computing technology, has been applied to various parallel and distributed computing problem solutions. Several mobile agent systems have been built to drive the agents following a platform dependant scheme, and some formal approaches have been proposed to describe mobile agents’ behaviors or properties for respective purposes. However, there remains a lack of a standard approach to describing a mobile agent algorithm and its semantics from the viewpoint of a practical program, which makes it difficult to specify an algorithm unambiguously and verify its correctness formally. This paper proposes a practical approach to overcome that difficulty by defining a script language and associated mechanisms to specify and verify mobile agent algorithms. The language, called SMAL, can describe mobile agent’s behaviors clearly due to its explicitly defined semantics. Based on the semantics, a transformation function for converting the specified algorithm to its equivalent specification in Mobile UNITY, a well‐known mobile computation formal approach for correctness verification, is presented. Formal verification of the algorithms can be accomplished based on the UNITY‐logic rules.

Abstract
Purpose
This paper aims to examine the impact of humble leadership on project success. The authors propose that such an effect is mediated by team-building, and top management support moderates the direct relationship (humble leadership and project success) as well as an indirect relationship through team-building.
Design/methodology/approach
Data were collected from 337 individuals employed in the information technology sector of Pakistan. A two-step approach consisting confirmatory factor analysis and structural equation modeling was used for analysis. To examine conditional direct and indirect effects, the authors utilized model 8 in PROCESS.
Findings
The results showed that humble leadership is positively related to project success. Furthermore, team-building partially mediates the relationship between humble leadership and project success. Moreover, top management support was anticipated to have a moderating effect on the direct and indirect link (via team-building) between humble leadership and project success.
Originality/value
Drawing on the conservation of resources theory, this study found that how humble leadership is vital for project success, and thus, extends the utility of the concept of humble leadership to the project literature.

Abstract
Purpose
This paper aims to examine the role of two mediating variables in the relationship between spiritual leadership with organizational citizenship behavior (OCB). The two mediating variables used in the study were organization-based self-esteem (OBSE) and workplace spirituality as followers’ intrinsic motivation and self-concept factors. Furthermore, the research also examined the role of perceived organizational support as moderating variable on the relationship between spiritual leadership and workplace spirituality.
Design/methodology/approach
A survey was conducted using questionnaires via a face-to-face method. The five-point Likert scale was used to assess the variables and to measure the items. The tool of analysis used was partial least square. The sample consisted of 234 respondents encompassing teachers and educational staffs of an Islamic based education institution in Indonesia.
Findings
The results supported five out of the eight proposed hypotheses. It was apparent that there was a partial mediating role of the OBSE as followers’ motivational concept on the relationship between spiritual leadership and organization citizenship behavior.
Research limitations/implications
The dearth of literature on the adoption of spiritual leadership in Islamic schools makes the depth of discussion on the study framework somewhat limited.
Practical implications
The insight provided by this study into understanding and link between spiritual leadership and OCB among Muslim education practitioners. While a large body of leadership research has adopted a variation of leadership theories, the results shifted the focus of attention to the adoption of spiritual leadership as an essential determinant of discretionary behavior in a religious-based institution.
Social implications
Islamic schools are in dire need of teachers with discretionary behavior. Spiritual leadership proved to have a significant relationship with organizational based self-esteem and OCB. It promotes the intrinsic well-being of the follower by creating a vision where people can achieve their higher purposes of life and contributing to society by performing services to others, and by giving people a feeling of being appreciated.
Originality/value
The study extends scholarly understanding on the role of spiritual leadership, which is a relatively new and growing area of interest for academics and practitioners, in shaping teachers and academic staffs’ OCBs regarding both theory and practice.

Abstract
Purpose
As Chinese imported cross-border e-commerce has entered a stage of rapid development, the problem of consumer shopping risk is increasingly prominent and the crisis of consumer trust is intensified. The theory of establishing consumer trust in traditional online shopping can no longer meet the need of cross-border context.
Design/methodology/approach
The researchers used the methods of network logs and grounded theory. The data collection and analysis are conducted on consumer comments from Tmall Global, NetEase Koala and JD Worldwide in the product comment area. This article explored and extracted the moderating variables of consumer perceived risk and cross-border characteristics in cross-border e-commerce. Based on the theory of “perceived risk – consumer trust – consumer purchase decision – making,” this article deduced mechanism of consumer dynamic trust based on the whole process of cross-border e-commerce transaction.
Findings
In the prepurchase, purchase and postpurchase stages of cross-border e-commerce transactions, consumers' perceived cognitive risk, transaction risk and utility risk are moderated by the cultural distance, geographical distance and institutional distance caused by the cross-border transaction subjects. On this basis, the preinfluence factors of trust in each transaction stage are synthesized to respectively influence the establishment of cognitive trust, emotional trust and behavioral trust, so as to affect consumers to make the order payment, confirm receipt and praise repurchase decisions. At the same time, with the advance of prepurchase, purchase and postpurchase transactions in cross-border online shopping, consumer trust presents a dynamic evolutionary path of “cognitive trust – emotional trust – behavioral trust.”
Originality/value
This article expands the application context of the theory of consumer rational behavior from traditional online shopping to the context of cross-border online shopping and expands the scope of interpretation of the theory of consumer rational behavior. This article also supplements the theoretical gaps in the dynamic evolution of consumer trust in cross-border online shopping, enriches the decision-making process model of consumers in the context of cross-border online shopping and provides new ideas for follow-up research.

Abstract
Purpose
The purpose of this paper is to investigate the effect of online service failure on online customer satisfaction and offline customer loyalty, and the moderating role of brand strength is also examined. While extant research on brick and click service mode recognizes the positive spillover effect from offline stores to online stores, this study analyzes the negative spillover effect from online stores to offline stores.
Design/methodology/approach
This paper tests the hypotheses by two studies. Study 1 is based on a 2 (failure severity: mild vs severe) × 2 (brand strength: strong vs weak) between-subjects experimental design using scenarios in a brick and click retailer context, while study 2 is based on data collected from a scenario-based questionnaire survey and analyzed through the structural equation modeling.
Findings
The results indicate that participants exposed to severe online service failure show lower online satisfaction as compared to their counterparts exposed to mild online service failure, but they show the similar level of offline loyalty in both degrees of online service failure. Nevertheless, these results are not moderated by brand strength significantly.
Research limitations/implications
An experimental design and a scenario-based questionnaire survey are used to test the framework. However, the generalizability of the research findings is still limited to a specific study setting. Future research in a different setting is needed to further validate the presented findings.
Practical implications
The findings suggest that physical service providers should adopt aggressive online expansion strategy to seize the market and pay more attention to online service quality rather than online marketing only.
Originality/value
This is one of few studies to explore the risk of brick and click service mode, and provide a clear understanding of the likely occurrence of online service failure and its impact on online customer satisfaction and offline customer loyalty. It extends prior research by exploring non-existence of negative perceptual effect from online service failure to offline customer loyalty in the short run and weakening brand effect, which contributes to cross-channel spillover effect in the integrated multi-channel context and brand building in the internet era.

Abstract
Purpose
This study proposes that the three core underpinnings of dynamic managerial capabilities (DMCs) – managerial cognition, managerial human capital and managerial social capital – represent individual-level micro-foundations that influence corporate social responsibility (CSR). It further explores the interaction mechanism between the three underpinnings in influencing CSR, and their influence depends on the technological turbulence caused by big-data-related technologies.
Design/methodology/approach
This study uses a quantitative research method and partial least squares structural equation modelling (PLS-SEM) to test the relationship between latent factors based on a sample of 270 Chinese top managers.
Findings
The three core underpinnings of DMCs are positively related to CSR. Managerial human capital and managerial social capital mediate the relationship between managerial cognition and CSR. Technological turbulence's moderating effects are also tested. Specifically, technological turbulence amplifies the positive relationship between managerial cognition, managerial human capital and CSR but negatively moderates the relationship between managerial social capital and CSR.
Originality/value
Why are some firms more willing to participate in CSR than others mainly depend on the fact that the actual participants of CSR are the top managers who formulate strategies and implement CSR plans. This study, grounded in the DMCs framework and the upper echelons perspective, is arguably the first to link DMCs' three core underpinnings and CSR, and further explore the multiple drivers' mechanisms and boundary conditions. This study contributes to individual micro-foundation of CSR literature, and advances the understanding of whether and how top managers influence CSR engagement.

Abstract
Purpose
To predict the price of battery-grade lithium carbonate accurately and provide proper guidance to investors, a method called MFTBGAM is proposed in this study. This method integrates textual and numerical information using TCN-BiGRU–Attention.
Design/methodology/approach
The Word2Vec model is initially employed to process the gathered textual data concerning battery-grade lithium carbonate. Subsequently, a dual-channel text-numerical extraction model, integrating TCN and BiGRU, is constructed to extract textual and numerical features separately. Following this, the attention mechanism is applied to extract fusion features from the textual and numerical data. Finally, the market price prediction results for battery-grade lithium carbonate are calculated and outputted using the fully connected layer.
Findings
Experiments in this study are carried out using datasets consisting of news and investor commentary. The findings reveal that the MFTBGAM model exhibits superior performance compared to alternative models, showing its efficacy in precisely forecasting the future market price of battery-grade lithium carbonate.
Research limitations/implications
The dataset analyzed in this study spans from 2020 to 2023, and thus, the forecast results are specifically relevant to this timeframe. Altering the sample data would necessitate repetition of the experimental process, resulting in different outcomes. Furthermore, recognizing that raw data might include noise and irrelevant information, future endeavors will explore efficient data preprocessing techniques to mitigate such issues, thereby enhancing the model’s predictive capabilities in long-term forecasting tasks.
Social implications
The price prediction model serves as a valuable tool for investors in the battery-grade lithium carbonate industry, facilitating informed investment decisions. By using the results of price prediction, investors can discern opportune moments for investment. Moreover, this study utilizes two distinct types of text information – news and investor comments – as independent sources of textual data input. This approach provides investors with a more precise and comprehensive understanding of market dynamics.
Originality/value
We propose a novel price prediction method based on TCN-BiGRU Attention for “text-numerical” information fusion. We separately use two types of textual information, news and investor comments, for prediction to enhance the model's effectiveness and generalization ability. Additionally, we utilize news datasets including both titles and content to improve the accuracy of battery-grade lithium carbonate market price predictions.
