Drawing on the dynamic capabilities theory, this paper proposes that supply chain (SC) strategies (i.e. the lean SC and agile SC strategies) will mediate the relationship between big data analytics (BDA) and SC performance. Furthermore, from the perspective of strategic alignment, this study hypothesizes that the effect of the SC strategy on SC performance is differently moderated by the information system (IS) strategy (i.e. the IS innovator and IS conservative strategies).

This study used 159 match-paired questionnaires collected from Chinese firms to empirically test the hypotheses.

Results show the positive direct and indirect impact of BDA on SC performance. Specifically, the lean and agile SC strategies mediate the relationship between BDA and SC performance. Furthermore, the results indicate that the IS innovator and IS conservative strategies differentially moderate the effect of the lean and agile SC strategies on SC performance. Specifically, the IS innovator strategy positively moderates the effect of the agile SC strategy on SC performance. By contrast, the IS conservative strategy positively moderates the effect of the lean SC strategy on SC performance but negatively moderates the effect of the agile SC strategy on SC performance.

This study provides a comprehensive understanding of how SC and IS strategies can help firms leverage BDA to improve SC performance.

This study aims to investigate the impact of enterprise social media (ESM) usage on employee agility through communication quality and visibility. Theory of communication visibility is used to explore the moderating role of ESM-related strain in the relationship among communication quality, visibility and employee agility.

The research model is analyzed using data from 240 Chinese employees of different companies. The proposed hypotheses are tested using structural equation modeling, hierarchical regression and mediation analysis.

Findings suggest that ESM usage is positively related to communication quality and visibility. Communication visibility mediates the relationship between ESM usage and employee agility. ESM-related strain reduces the relationship between communication visibility and employee agility. However, ESM-related strain has an insignificant moderating effect on the relationship between communication quality and employee agility.

The present study examines how employee agility is associated with ESM usage in the workplace. The mediating effects of communication quality and visibility are explored using a theoretical foundation. This study provides empirical evidence on how the impact of ESM on employee agility is transmitted through communication visibility. Lastly, the current study quantifies the advantages of ESM for organizations and may motivate managers to confidently deploy ESM in the workplace.

Most previous thermal-mechanical modeling of cold-formed steel (CFS) walls did not consider the failure of screwed connections under fire conditions because of the limited data of such connections at elevated temperatures.

In this study, 285 steady-state tests are conducted on CFS screwed connections with single-layer gypsum plasterboard (GPB) and Bolivian magnesium board (BMB) sheathing at ambient and elevated temperatures. The failure of these connections is described as the breaking of the loaded sheathing edge.

For the BMB sheathing screwed connections, hydrochloric acid gas is generated and released above 300°C, and the shear strength becomes much less than that of the GPB sheathing screwed connection above 370°C. Hence, BMB may not be suitable for use as the face-layer sheathing of CFS walls but is still recommended to replace GPB as the base-layer sheathing. The major influencing parameters on the shear strength of screwed connections are identified as the type of sheathing material and the loaded sheathing edge distance.

Based on the previous and present test results, a unified expression for the residual shear strength of screwed connections with GPB and BMB is proposed at ambient and elevated temperatures with acceptable accuracy. It can be used as the basic input parameter of the numerical simulation of the CFS structures under fire conditions.

This study investigates how employees' work- and social-related use of social media can individually and interactively render different impacts on employees' performance in the context of internal or external social media.

To test the research model in these two different contexts, the authors collected data from 392 internal social media users and 302 external social media users in the workplace.

The data suggest that the respondents' job performance can be enhanced when using internal social media for work-related purposes and using external social media for social-related purposes. Meanwhile, the interaction of work- and social-related use is positive for external social media but negative for internal social media on job performance. These findings highlight the significant distinction of social media use in the workplace.

First, this study contributes to the literature on the business value of IT by providing theoretical arguments on how companies can capitalize efforts to consider work-related use in combination with social-related use to create business value. Second, this research theorizes two distinct yet interacting views of social media use. The authors offer a more granular insight of the paths from work- and social-related use to employee performance instead of encapsulating social media use in a unitary concept and linking it simply and broadly to employee performance. Third, this research considers the interdependent effects of work- and social-related use on employee performance, and thus goes beyond the independent roles of these two types of social media use. Fourth, the authors find that the links from employees' work- and social-related use of social media to job performance vary in different contexts.

Corporate social responsibility (CSR) has gradually come to be regarded as a strategic business tool, and has a significant influence on consumers’ behaviours, but few studies discuss CSR regarding consumers’ behaviour in the insurance industry. The purpose of this paper is to investigate the effects of CSR on corporate reputation and customer loyalty.

This paper used a survey to assess consumers’ perception regarding CSR activities from non-life insurance industries. The questionnaires were administered to consumers who have purchased insurance in Taiwan. The survey questions were tested through an exploratory factor analysis. An analysis of variance and multiple regressions were performed to test the hypotheses.

The empirical results demonstrate that CSR activities have significantly positive influences on corporate reputation and customer loyalty. Additionally, CSR activities also have significantly positive influences on brand image. Furthermore, the study indicates the mediating role of brand image on CSR, corporate reputation and customer loyalty.

This paper establishes the mediating role of brand image among CSR, corporate reputation and customer loyalty for non-life insurance industries. Additionally, the empirical results focus on analysing the impact of CSR on customer’s behaviour, and strongly encourage insurers to continue investing; CSR and brand image can be strategic marketing tools and promote the sustainable development of insurance.

Based on the aerodynamic loads and dynamic performances of trains, this study aims to investigate the effect of crosswinds and raindrops on intercity trains operating on viaducts to ensure the safe operation of intercity railways in metropolitan areas.

An approach coupled with the Euler multiphase model as well as the standard k-ɛ turbulence model is used to investigate the coupled flow feature surrounding trains and viaducts, including airflow and raindrops, and the numerical results are validated with those of the wind tunnel test. Additionally, the train’s dynamic response and the operating safety region in different crosswind speeds and rainfall is investigated based on train’s aerodynamic loads and the train wheel–rail dynamics simulation.

The aerodynamic loads of trains at varying running speeds exhibit an increasing trend as the increase of wind speed and rainfall intensity. The motion of raindrop particles demonstrates a significant similarity with the airflow in wind and rain environments, as a result of the dominance of airflow and the supplementary impacts of droplets. As the train’s operating speed ranged between 120 and 200 km/h and within a rainfall range of 20–100 mm/h, the safe operating region of trains decreased by 0.56%–7.03%, compared with the no-rain condition (0 mm/h).

The impact of crosswind speeds and rainfall on the train’s aerodynamic safety is studied, including the flow feature of crosswind and different particle-sized raindrops around the train and viaduct, aerodynamic loads coefficients suffered by the intercity train as well as the operating safety region of intercity trains on the viaduct.

In this letter, based on the infinitesimal transformations with respect to the generalized coordinates and generalized momentums, we obtain the definition, determining equations and structure equation of the momentum‐dependent symmetry for the systems. This study directly leads to the non‐ Noether type conserved quantity for the systems. Further we also give the inverse issue of the momentum‐dependent symmetries of the systems. However, a theory of momentum‐dependent symmetries of the nonconservative Hamiltonian systems is established. Finally, an example is discussed to illustrate the results.

In this paper, the international progress of Nationally Appropriate Mitigation Actions (NAMAs), Intended Nationally Determined Contributions (INDCs), and Nationally Determined Contributions (NDCs) under the United Nations Framework Convention on Climate Change are reviewed. The content of Taiwan’s NAMAs and INDCs are also investigated, especially with reference to actions for the electricity sector. To better understand the greenhouse gas (GHG) reduction contribution from the electricity sector, this paper aims to examine challenges and solutions for implementing a carbon trading mechanism in Taiwan’s monopolistic electricity market under the newly passed Greenhouse Gases Emissions Reduction and Management Act (GHG ERMA).

Carbon reduction strategies for the electricity sector are discussed by examining and explaining Taiwan’s official documents and the law of GHG ERMA.

This study finds that market mechanisms should be utilized to allocate appropriate costs and incentives for GHG reductions to transform Taiwan into a low-carbon society.

This study identifies strategies for the electricity sector to reduce GHG emissions, especially the operation of a carbon-trading scheme under a non-liberalized electricity market.

The purpose of this paper is to prove the importance of both cluster leadership and identification on cluster innovation.

The case studies presented in this study involve a cluster by micro-enterprises in Yilan, Taiwan. Data collected during interviews, observations and secondary data provide understanding and practices for the impact of cluster identification on cluster innovation.

This study proved: first, the importance of cluster identification on innovation by representing the need of consensus and collaboration of the members in conducting innovation actions; and second, the cluster identification is influenced by the cluster leadership by showing high satisfaction of the leader, close interaction between the members and high identification with the cluster.

This study predicts the ongoing cluster innovation activities will be achieved due to the transformational leadership and high cluster identification.

This study enriches the factors of cluster innovation accomplishment and proposes the important of cluster identification, which has not been discussed much in the past.

Organizations use enterprise social media (ESM) platforms to operate, function, and develop. However, the effectiveness of the use of ESM is inconclusive. This study aims to explore the mechanism and boundary conditions of the relationship between employee ESM use and job performance.

This study uses a 2-wave survey design, with a final sample of 481 employees from a large automobile company.

The results indicate that ESM use is beneficial and detrimental to job performance. On the one hand, ESM use is positively related to work overload, decreasing job performance. On the other hand, ESM use is positively associated with informational support, increasing job performance. A mediation test revealed that both work overload and informational support mediate the relationship between ESM use and job performance. Furthermore, job autonomy weakens the positive relationship between ESM use and work overload, but strengthens the positive relationship between ESM use and informational support.

This study provides a more balanced view of how ESM use influences job performance by demonstrating the opposing mediating roles of work overload and informational support. Further, this study fills a research gap by considering job characteristics when examining the boundary conditions of ESM use. Third, this study validates the generalization of the job demands-resources model in social media research.
