Abstract
Purpose
Drawing on the knowledge-based view, this study investigates how IT–business alignment influences business model design via organizational learning and examines the moderating role of data-driven culture in the relationship between IT–business alignment and business model design via organizational learning.
Design/methodology/approach
Using multi-respondent survey data collected from 597 Chinese firms, mediation and moderated mediation analyses were used to examine this study's hypotheses.
Findings
The mediation test results revealed organizational learning served as a mediator between IT–business alignment and two types of business model design (i.e. novelty- and efficiency-centered). In addition, data-driven culture strengthened the indirect effects of IT–business alignment on these two types of business model design via organizational learning.
Originality/value
This study extends current understandings of the relationship between IT–business alignment and business model design by revealing the mediating role of organizational learning and investigating its indirect effects under various degrees of data-driven culture. As such, it contributes to the literature on the business model and IT–business alignment and provides insights for managers seeking to achieve the expected business model design.

This study aims to improve the passenger accessibility of passenger demands in the end-of-operation period.
Abstract
Purpose
This study aims to improve the passenger accessibility of passenger demands in the end-of-operation period.
Design/methodology/approach
A mixed integer nonlinear programming model for last train timetable optimization of the metro was proposed considering the constraints such as the maximum headway, the minimum headway and the latest end-of-operation time. The objective of the model is to maximize the number of reachable passengers in the end-of-operation period. A solution method based on a preset train service is proposed, which significantly reduces the variables of deciding train services in the original model and reformulates it into a mixed integer linear programming model.
Findings
The results of the case study of Wuhan Metro show that the solution method can obtain high-quality solutions in a shorter time; and the shorter the time interval of passenger flow data, the more obvious the advantage of solution speed; after optimization, the number of passengers reaching the destination among the passengers who need to take the last train during the end-of-operation period can be increased by 10%.
Originality/value
Existing research results only consider the passengers who take the last train. Compared with previous research, considering the overall passenger demand during the end-of-operation period can make more passengers arrive at their destination. Appropriately delaying the end-of-operation time can increase the proportion of passengers who can reach the destination in the metro network, but due to the decrease in passenger demand, postponing the end-of-operation time has a bottleneck in increasing the proportion of passengers who can reach the destination.

Abstract
Purpose
The aim of this study is to numerically simulate the density-driven convection in heterogeneous porous media associated with anisotropic permeability field, which is important to the safe and stable long term CO2 storage in laminar saline aquifers.
Design/methodology/approach
The study uses compact finite difference and the pseudospectral method to solve Darcy’s law.
Findings
The presence of heterogeneous anisotropy may result in non-monotonic trend of the breakthrough time and quantity of CO2 dissolved in the porous medium, which are important to the CO2 underground storage.
Originality/value
The manuscript numerically study the convective phenomena of mixture contained CO2 and brine. The phenomena are important to the process of CO2 enhanced oil recovery. Interesting qualitative patterns and quantitative trends are revealed in the manuscript.

Abstract
Purpose
The factors contributing to skilled labor shortages in the construction industry are investigated based on relevant global literature. The potential factors are collected, organized and subjected to expert evaluation to determine their inter-relationships. The identified factors are integrated to determine both direct and indirect impacts, clarifying their relative importance.
Design/methodology/approach
Apart from literature reviews, the decision-making trial and evaluation laboratory (DEMATEL) method was employed to elucidate influential relationships among the factors. Intuitive assessments and DEMATEL with and without the shortage factors were used to compare the impact of various factors on skilled labor shortages.
Findings
Significant differences were observed between considering only direct effects and both direct and indirect effects. Factors identified through comprehensive evaluation were prioritized; poor overall wages, poor overall welfare and lack of retirement income security and unclear career path owing to lack of prospects and talent plans were the three important factors identified.
Research limitations/implications
The disparity between construction companies and key stakeholders, such as government agencies, public sector clients, pre-project planners, designers and consulting engineers, stems from differing priorities concerning skilled labor in the construction industry. In this study, evaluations of most experts from construction companies and the gap ratio for data reliability were implemented for the analysis. In the future, more experts from government agencies, and other groups should be included while focusing on the shortage in individual trades of skilled workers. In addition, the proposed measures require further evaluation for interactive influence and effectiveness.
Originality/value
The interactive relationship among the factors influencing skilled labor shortages is explored to determine measures to alleviate their influence. This can aid policymakers in identifying effective solutions.

Abstract
Purpose
This paper aims to solve the problem of public resource allocation among vulnerable groups by proposing a new method called uncertain α-coordination value based on uncertain cooperative game.
Design/methodology/approach
First, explicit forms of uncertain Shapley value with Chouqet integral form and uncertain centre-of-gravity of imputation-set (CIS) value are defined separately on the basis of uncertainty theory and cooperative game. Then, a convex combination of the two values above called the uncertain α-coordination value is used as the best solution. This study proves that the proposed methods meet the basic properties of cooperative game.
Findings
The uncertain α-coordination value is used to solve a public medical resource allocation problem in fuzzy coalitions and uncertain payoffs. Compared with other methods, the α-coordination value can solve such problem effectively because it balances the worries of vulnerable group’s further development and group fairness.
Originality/value
In this paper, an extension of classical cooperative game called uncertain cooperative game is proposed, in which players choose any level of participation in a game and relate uncertainty with the value of the game. A new function called uncertain α-Coordination value is proposed to allocate public resources amongst vulnerable groups in an uncertain environment, a topic that has not been explored yet. The definitions of uncertain Shapley value with Choquet integral form and uncertain CIS value are proposed separately to establish uncertain α-Coordination value.

In gearbox fault diagnosis, identifying the fault type and severity simultaneously, as well as the compound fault containing multiple faults, is necessary.
Abstract
Purpose
In gearbox fault diagnosis, identifying the fault type and severity simultaneously, as well as the compound fault containing multiple faults, is necessary.
Design/methodology/approach
To diagnose multiple faults simultaneously, this paper proposes a multichannel and multi-task convolutional neural network (MCMT-CNN) model.
Findings
Experiments were conducted on a bearing dataset containing different fault types and severities and a gearbox compound fault dataset. The experimental results show that MCMT-CNN can effectively extract features of different tasks from vibration signals, with a diagnosis accuracy of more than 97%.
Originality/value
Vibration signals at different positions and in different directions are taken as the MC inputs to ensure the integrity of the fault features. Fault labels are established to retain and distinguish the unique features of different tasks. In MCMT-CNN, multiple task branches can connect and share all neurons in the hidden layer, thus enabling multiple tasks to share information.

Abstract
Purpose
Valuers should independently assess market value. The purpose of this article is to analyze whether the valuation behavior remains independent when commissioned by publicly listed companies in Taiwan.
Design/methodology/approach
This study used both quantitative and qualitative methods. Quantitative data analysis was used to examine the estimated premium ratio and estimated divergent ratio with the independent sample t test and Wilcoxon-Mann-Whitney test. To complement and validate the quantitative analysis, open-ended questionnaires were conducted, providing additional insights into the research findings.
Findings
The results showed that there is a significant difference in estimated valuations commissioned by representatives of buyers and sellers, and the estimated premium ratios commissioned by representatives of buyers were higher than those of sellers. Furthermore, the open-ended questionnaires results indicate that these findings may be influenced by clients for less experienced appraisers. However, for senior appraisers, this is seen as an action to gain a better understanding of the valuation purpose and always within a reasonable price range. In addition, client influence is not a static factor; it may transform into the valuer's behavior as the appraiser's experience grows and deepens.
Practical implications
It is difficult to obtain valuation reports commissioned by representatives of both buyers and sellers for the same property transactions. In this study, data were obtained from the Market Observation Post-System (MOPS) in Taiwan. As valuation reports could not be obtained, estimated valuations and transaction prices are used to calculate estimated premium ratio and estimated divergent ratios.
Originality/value
Previous investigations of the client effect have been conducted using qualitative methods including questionnaire surveys, in-depth interviews and experimental design. However, these studies are subject to moral hazard. This study may be the first study that has access to data on valuations for both buyers and sellers in such a formal setting.

The study aims to examine the effect of inclusions and inherent microstructure on fatigue behavior of 34Cr2Ni2Mo steel.
Abstract
Purpose
The study aims to examine the effect of inclusions and inherent microstructure on fatigue behavior of 34Cr2Ni2Mo steel.
Design/methodology/approach
Fatigue behavior of 34Cr2Ni2Mo steel was investigated for up to 1E10 cycles.
Findings
Results showed that both inclusion and inherent microstructure have an influence on the crack initiation mechanism. Fatigue cracks mostly initiated from inclusions, whereas substrate-induced crack initiations were also observed. Fatigue life of inclusion-induced failures is mostly determined by the location of inclusions rather than the loading stress. The inherent microstructure seems to tolerate inclusions at a lower stress level in very high-cycle regime owing to the absence of internal inclusion-induced failure. For the substrate-induced crack initiations, high-density dislocations are found to be accumulated around the carbide particle-matrix interface, which may be the cause of crack initiation in the inherent structure due to strain localization.
Originality/value
The effect of inclusions and inherent microstructure on fatigue behavior of 34Cr2Ni2Mo steel up to 1E10 cycles.
Highlights
Fatigue failure occurs even at a lifetime of 5.76E9 cycles.
Surface inclusion induced premature failures.
Inherent microstructure tolerates inclusions at lower stress level.
Internal carbides promote substrate-induced crack initiations.

Abstract
Purpose
This paper aims to explore the influence of information technology (IT) capability (i.e. IT exploration and exploitation) on service innovation and ultimately financial performance in manufacturing firms. Moreover, this paper examines the contingent role of cross-functional integration (CFI) on the IT capability–service innovation relationship.
Design/methodology/approach
This study employs seemingly unrelated regression to test the theoretical model based on survey data from 121 manufacturers in China.
Findings
IT exploration is positively related to radical and incremental service innovations, whereas IT exploitation is only positively related to radical service innovation. CFI positively moderates the relationship between IT exploitation and service innovation. Radical and incremental service innovations are positively related to manufacturers' financial performance.
Originality/value
This study contributes to existing information systems and servitization literature by uncovering the varying effects of IT exploration and exploitation on radical and incremental service innovations and by revealing the different contingent roles of CFI in moderating the above effects in the manufacturing context.

Abstract
The present chapter aims to provide a holistic perspective by investigating how passion types can have a role on entrepreneurs’ target of passion with the integration of Hofstede’s cultural dimensions. A conceptual framework was administered in order to build the association between passion types and targets of passion in the light of the literature by which harmonious and obsessive passions are proposed to be the determinants of different targets of entrepreneurs’ passion. Additionally, based on the extant literature, the role of culture in shaping the entrepreneurs’ target of passion is addressed by utilizing Hofstede’s cultural approach. Seven major propositions were discussed to provide a comprehensive understanding of entrepreneurial passion and targets of passion.
