Abstract
Purpose
The purpose of this paper is to explore the effect of the feeling awe on individuals' endorsement of conformist attitudes in consumption choices and the mediating role of social connectedness in generating this effect.
Design/methodology/approach
We test our hypotheses across three studies. Study 1 used an online survey. Study 2 and 3 conducted two laboratory experiments to induce awe and measured consumer conformity in two consumption choice tasks.
Findings
This research shows that both dispositional awe and induced awe can increase individuals' preferences for majority-endorsed vs. minority-endorsed choice alternatives in subsequently unrelated consumption situations, and this effect is mediated by perceptions of social connectedness with other decision-makers.
Practical implications
Marketers can promote the sales of mass-market products through inducing awe.
Social implications
Public regulators could utilize people's incidental awe as an effective policy intervention to nudge individual cooperation in some cases.
Originality/value
The research is the first to demonstrate a novel consequence of awe on consumer decision-making. It also highlights the significance of desire for social connectedness that explains why the feeling of awe develops conformity to the opinions of unknown people.

Abstract
Purpose
Aerospace assembly demands high drilling position accuracy for fastener holes. Hole position error correction is a key issue to meet the required hole position accuracy. This paper aims to propose a combined hole position error correction method to achieve high positioning accuracy.
Design/methodology/approach
The bilinear interpolation surface function based on the shape of the aerospace structure is capable of dealing with position error of non-gravity deformation. A gravity deformation model is developed based on mechanics theory to efficiently correct deformation error caused by gravity. Moreover, three solution strategies of the average, least-squares and genetic optimization algorithms are used to solve the coefficients in the gravity deformation model to further improve position accuracy and efficiency.
Findings
Experimental validation shows that the combined position error correction method proposed in this paper significantly reduces the position errors of fastener holes from 1.106 to 0.123 mm. The total position error is reduced by 43.49% compared with the traditional mechanics theory method.
Research limitations/implications
The position error correlation method could reach an accuracy of millimeter or submillimeter scale, which may not satisfy higher precision.
Practical implications
The proposed position error correction method has been integrated into the automatic drilling machine to ensure the drilling position accuracy.
Social implications
The proposed position error method could promote the wide application of automatic drilling and riveting machining system in aerospace industry.
Originality/value
A combined position error correction method and the complete roadmap for error compensation are proposed. The position accuracy of fastener holes is reduced stably below 0.2 mm, which can fulfill the requirements of aero-structural assembly.

Abstract
Purpose
This paper aims to study the boundary disturbance rejection control design for a flexible Timoshenko robot arm to diminish external disturbances and achieve desired angle tracking, with system vibration and elastic deformation considered.
Design/methodology/approach
This study introduces disturbance observer and disturbance rejection mechanism into the boundary control design for flexible Timoshenko robot arm systems. The uniform bounded stability of controlled systems is proved via Lyapunov analysis without any simplification of the infinite-dimensional system dynamics.
Findings
The proposed boundary disturbance rejection control scheme can effectively suppress vibrations and shear deformations, achieve the required angular positioning and reject external disturbances. Numerical simulations developed by the finite difference method are adapted to demonstrate the validity of the designed controller.
Originality/value
The originality of this study is to design boundary disturbance rejection control to suppress vibrations and shear deformations for the flexible Timoshenko robot arm, thereby improving the performance and control accuracy of the system.

Abstract
Purpose
The purpose of the paper is to study the dyeing process of three-dimensional-printed (3DP) fabrics, and then study the wearability of the fabrics before and after dyeing to provide a feasible dyeing method of 3DP clothes.
Design/methodology/approach
In this regard, the thermoplastic polyurethane (TPU) was applied during the process of 3DP. Then, the imitation twill weave (ITW) was printed with fused deposition modeling (FDM) technology using TPU and the suspension of Disperse Blue 2BLN (as a dye) was prepared. After that, the single factor analysis and orthogonal experiment of dyeing were combined to obtain the optimized dyeing process. And then, ITW fabrics were dyed through the weak acid-low temperature dyeing method. In the end, in order to discuss the wearability of ITW fabrics, the dyeing experiments, including permeability, wrinkle recovery angle, bending rigidity, crock fastness and washing colorfastness were carried out.
Findings
The surface morphology of TPU before and after spinning was established by field emission scanning electron microscopy (FE-SEM), which was confirmed the surface of TPU getting smoother after spinning. The wearability of the fabric after dyeing was not affected compared with before dyeing. Moreover, both colorfastness grades were above 4–5 with high colorfastness.
Originality/value
The article provides a method for 3DP dyeing, which can solve the problem of a single color. And the wearability demonstrates that 3DP fabrics after dyeing-based TPU have more value for clothing than before dyeing.

Abstract
Purpose
In the context of collaborative research and development (R&D), multi-actor participation and multi-resource integration of technological knowledge has become the mainstream paradigm for the R&D and spillover of industry generic technology (GT). As GT's core characteristics, “fundamentality” and “externality,” make differential requests on knowledge bases regarding the R&D and spillover of GT (SGT). Knowledge breadth can enhance the generality of technology. The purpose of this paper is to integrate “generic technology R&D” and “generic technology spillover” into a single study, and try to solve the theoretical problem of “whether broader mean more general?”
Design/methodology/approach
This paper collects and collates the patent data from the two patent databases of Derwent and SooPAT, and then makes an empirical analysis of the patent data collected by the authors with the data analysis software Stata.
Findings
Taking 352 strategic emerging firms in China as the sample, this paper examined the effects of general knowledge breadth (GKB) and specific knowledge breadth (SKB) on the R&D and SGT. The authors concluded that both general and SKB have a positive effect on the R&D of GT (RGT), and the latter has a greater effect. There is a significant inverted U-shaped relationship between SKB and SGT.
Originality/value
The theoretical contributions of this paper are as follows. GT can effectively link different technologies and knowledge fields (Gambardella and Giarratana, 2013; Appio et al., 2017a, b). Therefore, existing studies regard the role of knowledge breadth on the R&D and SGT as an existing hypothesis. This paper challenges such hypothesis in two ways. First, this paper divides knowledge breadth into “general knowledge breadth” and “specific knowledge breadth” in response to the insufficient division of knowledge breadth in previous research, although some existing studies have examined the antecedents of the R&D and SGT from the perspective of R&D and SGT. Thus, the authors define GKB as the scope of context-free knowledge and SKB as the scope of context-specific knowledge, both of which shows differential nature, source and application. Second, this paper decomposes the effect of knowledge breadth on RGT, as well as on SGT, basing on distinguishing the SKB from GKB. Existing research reaches a consensus of the positive role of knowledge breadth, no matter on RGT or SGT (e.g. Schmidt et al., 2016; Appio et al., 2017a, b). Yet, such hypothesis ignores the refinement and decomposition of “knowledge breadth” in the research field of R&D and SGT, which is essential in promoting the development of GT theory. In this paper, the authors find that these two types of knowledge breadths play different roles in the RGT, and especially SKB plays a double-edged sword effect on the SGT.

Abstract
Purpose
The purpose of this paper is to outline some key aspects such as material systems used, phenomenological and statistical process modeling, techniques applied to monitor the process and optimization approaches reported. All these need to be taken into account for the ongoing development of the SLM technique, particularly in health care applications. The outcomes from this review allow not only to summarize the main features of the process but also to collect a considerable amount of investigation effort so far achieved by the researcher community.
Design/methodology/approach
This paper reviews four significant areas of the selective laser melting (SLM) process of metallic systems within the scope of medical devices as follows: established and novel materials used, process modeling, process tracking and quality evaluation, and finally, the attempts for optimizing some process features such as surface roughness, porosity and mechanical properties. All the consulted literature has been highly detailed and discussed to understand the current and existing research gaps.
Findings
With this review, there is a prevailing need for further investigation on copper alloys, particularly when conformal cooling, antibacterial and antiviral properties are sought after. Moreover, artificial intelligence techniques for modeling and optimizing the SLM process parameters are still at a poor application level in this field. Furthermore, plenty of research work needs to be done to improve the existent online monitoring techniques.
Research limitations/implications
This review is limited only to the materials, models, monitoring methods, and optimization approaches reported on the SLM process for metallic systems, particularly those found in the health care arena.
Practical implications
SLM is a widely used metal additive manufacturing process due to the possibility of elaborating complex and customized tridimensional parts or components. It is corroborated that SLM produces minimal amounts of waste and enables optimal designs that allow considerable environmental advantages and promotes sustainability.
Social implications
The key perspectives about the applications of novel materials in the field of medicine are proposed.
Originality/value
The investigations about SLM contain an increasing amount of knowledge, motivated by the growing interest of the scientific community in this relatively young manufacturing process. This study can be seen as a compilation of relevant researches and findings in the field of the metal printing process.

Abstract
This study aims to examine the Environmental Kuznets Curve (EKC) hypothesis in the case of 100 developed and developing nations by taking into account the role of institutional quality (IQ). Using generalized method of moments (GMM) estimators, we find an inverted U-shaped relationship between economic growth and carbon dioxide (CO2) emissions only in the developed world but not in the developing nations. It is also revealed that control of corruption plays a vital role in reducing CO2 emissions in high income countries. Furthermore, rule of law is found to have a beneficial effect on the environment in all countries except for low income countries. Overall, our results confirm the importance of IQ in reducing CO2 emissions. Additionally, foreign direct investment contributes to CO2 reduction in rich countries while deteriorates the environmental quality in developing nations. Trade openness was shown to exert a positive impact on environmental quality in developing countries. These findings can be of great importance to policy makers of different income groups in designing appropriate economic and environmental policies toward the dual goals of high growth and low pollution.

Abstract
Purpose
This study aims to investigate the service performances of a new full-section asphalt concrete waterproof sealing structure (FSACWSS) for the high-speed railway subgrade through on-site tracking, monitoring and post-construction investigation.
Design/methodology/approach
Based on the working state of the waterproof sealing structure, the main functional characteristics were analyzed, and a kind of roller-compacted high elastic modulus asphalt concrete (HEMAC) was designed and evaluated by several groups of laboratory tests. It is applied to an engineering test section, and the long-term performance monitoring and subgrade dynamic performance testing system were installed to track and monitor working performances of the test section and the adjacent contrast section with fiber-reinforced concrete.
Findings
Results show that both the dynamic performance of the track structure and the subgrade in the test section meet the requirements of the specification limits. The water content in the subgrade of the test section is maintained at 8–18%, which is less affected by the weather. However, the water content in the subgrade bed of the contrast section is 10–35%, which fluctuates significantly with the weather. The heat absorption effect of asphalt concrete in the test section makes the temperature of the subgrade at the shoulder larger than that in the contrastive section. The monitoring value of the subgrade vertical deformation in the test section is slightly larger than that in the contrastive section, but all of them meet the limit requirements. The asphalt concrete in the test section is in good contact with the base, and there are no diseases such as looseness or spalling. Only a number of cracks are found at the joints of the base plates. However, there are more longitudinal and lateral cracks in the contrastive section, which seriously affects the waterproof and sealing effects. Besides, the asphalt concrete is easier to repair, featuring good maintainability.
Originality/value
This research can provide a basis for popularization and application of the asphalt concrete waterproof sealing structure in high-speed railways.

Abstract
Purpose
The UN Global Compact promotes values of precautionary approach to environmental changes and business sustainability, which are eagerly embraced by MNCs; however the recognized emerging country risks pose a challenge for continuous commitment to those principles in the subsidiaries. Especially political and currency risks are considered significant in the subsidiaries located in the emerging markets. Therefore, those risks are often shifted to the local partners as the pursued core principle of the risk management strategies. The objective of MNCs is in fact to limit MNCs responsibility for the liabilities and losses in the emerging markets in case of market downturns, and in effect the advocated risk management practices exacerbate the severity of the emerging market crises.
Methodology/approach
The chapter explores those corporate practices on the examples of numerous major international market players in case of several historical, but recent examples of the emerging market currency crises.
Findings
The concerns addressed in the chapter include: the preference for local financing exposing at risk local banking sectors in the emerging markets, excessive liquidity and minimal capital commitments and investments leading to weaker currency fluctuations and resulting in private capital speculations and capital flight (to safety or to quality). The intensified global competition for international investments in form of FDIs resulted in the erosion of the capital requirements, reduced social and business infrastructure commitments requested, limited currency controls, and other components of the regulatory framework easing in the emerging markets. Other identified in the research key components of the risk management strategies applied by MNCs, destabilizing the emerging markets in financial (both fiscal and currency) crises include: intercompany payments and financing such as: transfer pricing, local sourcing and reimbursements for both tangible and intangible assets transfer.
Implications
Demonstrated approach of MNCs appears ethically questionable and reflects the disparity of the bargaining powers. It also undermines the intentions of the Ten Principles of the UN Global Compact. The corporate citizenship is found difficult to dominate over the conflicting self-centered interests of MNCs operating in the emerging markets, especially in times of crises. The consideration of the non-compulsory ethically based initiative, as the alternative to the failing effectiveness of the international market regulations, requires restoration of the public and an individual value of the reputation (image, name) built on social responsibility and accountability, unfortunately so much diluted over the last two decades.
Originality/value
The chapter examines the effect of MNCs risk management of their foreign operations on the crises in the emerging markets with focus on inward FDIs flows and inward FDIs stock fluctuations and debt financing. The results evidence the repetitive nature of the self-interest driven corporate behavior.
