The purpose of this paper is to provide a theoretical account of how firms make choices between dynamic capability-based and ad hoc problem-solving approaches toward strategic change.

A model has been developed to answer the questions of how and under what conditions firms develop appropriate approaches to handle strategic change.

Drawing upon structural inertia theory (SIT) and the resource-based view (RBV), the model predicts that firms, regardless of their age and size, are more likely to adopt an ad hoc problem-solving approach to handle change in both highly dynamic and low-dynamic environments. However, in moderately dynamic environments, a dynamic capability-based approach may be more appropriate, depending on which theoretical logic (SIT or RBV) the decision is made.

The paper builds on the useful distinction made by Winter (2003) in terms of the ways to handle organizational change and extends the recent research on temporary vs sustainable competitive advantages to investigate how firms tackle strategic change within the contexts of both environmental dynamism and organizational attributes.

This paper aims to propose a novel statistic energy analysis method with fuzzy parameters to study the dynamic and acoustic responses of coupled system with fuzzy parameters, which can expand the applied range of statistic energy analysis method in engineering to some extent.

On the basis of the property of membership level, the uncertain fuzzy parameters are expressed as the interval forms. Interval mathematics and interval expansion principle are adopted to solve the problem with interval parameters. At last, two numerical examples, which include a two-plate coupled system and a single-partition sound-insulation system, are carried out to demonstrate the feasibility and validity of the presented method.

Interval mathematics and interval expansion principle are adopted to solve the problem with interval parameters.

By integrating the interval analysis, optimization technique and Taylor expansion method, two non-probabilistic, set-theoretical statistical energy analyses are proposed for predicting the dynamical and acoustical response of the complex coupled system with uncertain parameters in high-frequency domain.

The purpose of this paper is to design an automatic press-fit instrument to realize precision assembly and connection quality assessment of a small interference fitting parts, armature.

In this paper, an automatic press-fit instrument was developed for the technical problems of reliable clamping and positioning of the armature, automatic measurement and adjustment of the attitude and evaluation of the connection quality. To compensate for the installation error of the equipment, corresponding calibration method was proposed for each module of the instrument. Assembly strategies of axial displacement and perpendicularity were also proposed to ensure the assembly accuracy. A theoretical model was built to calculate the resistant force generated by the non-contact regions and then combined with the thick-walled cylinder theory to predict the press-fit curve.

The calibration method and assembly strategy proposed in this paper enable the press-fit instrument to achieve good alignment and assembly accuracy. A reasonable range of press-fit curve obtained from theoretical model can achieve the connection quality assessment.

This instrument has been used in an armature assembly project. The practical results show that this instrument can assemble the armature components with complex structures automatically, accurately, in high-efficiency and in high quality.

This paper provides a technical method to improve the assembly quality of small precision interference fitting parts and provides certain methodological guidelines for precision peg-in-hole assembly.

Retail investors are prone to be affected by information dissemination in social media with the rapid development of Web 2.0. The purpose of this study is to recognize the factors that may impact users' retweet behavior, namely information dissemination in the online financial community, through machine learning techniques.

This paper crawled data from the Chinese online financial community (Xueqiu.com) and extracted author-related, content-related, situation-related, stock-related and stock market-related features from the dataset. The best information dissemination prediction model based on these features was determined by evaluating five classifiers with various performance metrics, and the predictability of different feature groups was tested.

Five prevalent classifiers were evaluated with various performance metrics and the random forest classifier was proven to be the best retweet prediction model in the authors’ experiments. Moreover, the predictability of author-related, content-related and market-related features was illustrated to be relatively better than that of the other two feature groups. Several particularly important features, such as the author's followers and the rise and fall of the stock index, were recognized in this paper at last.

This study contributes to in-depth research on information dissemination in the financial domain. The findings of this study have important practical implications for government regulators to supervise public opinion in the financial market.

Many e-commerce companies adopt a product customization platform offering various choices for customers to configure products to better satisfy their needs. However, a method to effectively measure customer satisfaction is lacking. This paper aims to investigate customers' perception of time in the online configuration process of customized products and seeks to propose time perception as the measurement of the effectiveness of online product customization.

An online laptop customization system was used in an empirical experiment to collect respondents' answers in a set of research questions. Regression and correlation analysis were conducted to investigate the factors affecting customers' satisfaction as well as the relationships with time perception.

The experimental results reveal several factors in customers' perception of time during the online product customization process. First, customers tend to overestimate the amount of time spent in a short-duration task but underestimate the amount of time spent in a long-duration task. Second, customers' perceptions of time are significantly correlated with their satisfaction with the configured products, and perceived time is moderately correlated with their satisfaction with the configuration process. Third, the difficulty of customization tasks and customers' motivation to process information also significantly affect customers' perceptions of time.

This paper advances the research on time perception by developing a new relative segmentation-based method to estimate the subjective perception of time. This study also makes several contributions to product customization research: the authors fill a research gap in the field of product customization by incorporating customers' perceptions of time into the measurement of customer satisfaction and by identifying the significant relationships among customers' perception of time, the ease of task selection, the customers' motivation to process information, and customers' satisfaction with customized products. These results aid in the design of online product customization systems.

The purpose of this paper is to assess the orbital perturbation caused by the gravitational orbit–attitude coupling of spacecraft in the proximity of asteroids.

The gravitational orbit–attitude coupling perturbation (GOACP), which has been neglected before in the close-proximity orbital dynamics about asteroids, is investigated and compared with other orbital perturbations. The GOACP has its origin in the fact that the gravity acting on a non-spherical extended body is actually different from that acting on a point mass located at the body’s center of mass, which is the approximated model in the orbital dynamics. Besides, a case study of a tethered satellite system is given by numerical simulations.

It is found that the ratio of GOACP to the asteroid’s non-spherical gravity is the order of ρ/a_e, where ρ is the spacecraft’s characteristic dimension and a_e is the asteroid’s mean radius. It can also be seen that as ρ increases, GOACP will also increase but the solar radiation pressure (SRP) will decrease due to the decreasing area-to-mass ratio. The GOACP will be more significant than SRP at small orbital radii for a large-sized spacecraft. Based on the results by analyses and simulations, it can be concluded that GOACP needs to be considered in the orbital dynamics for a large-sized spacecraft in the proximity of a small asteroid.

This study is of great importance for the future asteroids missions for scientific explorations and near-Earth objects mitigation.

The GOACP, which has been neglected before, is revealed and studied.

Based on the team conflict theory and organizational learning theory, this study aims to discuss the two different types of conflicts of the top management team (TMT) on the different mechanisms of exploratory learning behavior of firms, and, based on the perspective of CEO-TMT (CEO – chief executive officer) interface, the different moderating effects caused by different CEO leadership styles are clarified.

Using the sample of 193 firms’ samples with multi-source data, the authors take an empirical test of the theoretical framework.

The effect of task conflict on exploratory learning behavior was insignificant, and relationship conflict had a positive effect on exploratory learning behavior. However, when CEO’s transformational leadership level was high, or transactional leadership level was low, there existed “bathtub curve” relationship between task conflict and exploratory learning behavior, and the relationship conflict under these conditions strengthened exploratory learning behavior. When CEO’s transactional leadership level was high, or transformational leadership level was low, there existed the inverted U-shaped relationship between task conflict and exploratory learning behavior, and the relationship conflict under such conditions weakened exploratory learning behavior.

First, the authors challenge the assumption of linear mechanism of task conflict, trying to build the mechanism of curve hypothesis, and the nonlinear explanation might be able to integrate the inconsistent results in the existing literature. Second, according to the inconsistent results of relationship conflict in existing literature, this study takes perspective of the CEO-TMT and introduces CEO leadership behavior as a moderating variable to test the moderating effect of CEO leadership and clarifies the boundary conditions of TMT conflicts.

Employees’ bootlegging innovation behavior is common and plays an important role in enterprise management. Based on the resource conservation theory and self-regulation theory, the purpose of this study is to explore the influence mechanism of leaders’ abusive supervision on employees’ bootlegging innovation behavior, with psychological safety as a mediator and mindfulness at workplace as a moderator.

Survey data were gathered from 591 employees’ self-assessment questionnaires in China. Hierarchical regression analysis was used to test the research model through SPSS and AMOS.

This study found that the leaders’ abusive supervision negatively affects employees’ bootlegging innovation behavior; employees’ psychological safety completely mediates the negative effect of leaders’ abusive supervision on employees’ bootlegging innovation behavior; and mindfulness at work moderates the influence of leaders’ abusive supervision on employee’ bootlegging innovation behavior, as well as the influence of leaders’ abusive supervision on employees’ psychological safety.

This study has significant implications in passive leadership that affect employees’ innovation. Authors found that leaders’ abusive supervise, mindfulness at workplace play a crucial role in employees’ bootleg innovation through psychological safety.

Theoretically, this study has enriched the antecedent research on employees’ bootlegging innovation behavior from the perspective of negative leadership behavior and employee psychology. And this study considered mindfulness at workplace as a boundary condition.

The change rules of the shielding effectiveness (SE) of the sleeve has not been clarified, which leads to the lack of the basis for the design, manufacture and evaluation of the electromagnetic shielding (EMS) clothing.

According to a simplified analysis model, a series of sleeve samples with different fabrics and styles are designed and manufactured. The SE of the sleeve is tested with the proposed special test method in a semi-anechoic chamber to analyze the influence of different factors on the SE of the sleeve.

The SE is greatly reduced about 60–90% after the fabric is manufactured into the sleeve. The larger the sleeve length is, the higher the peak value of the SE is. When the sleeve length is low, the SE value is easy to appear negative. As the cuff circumference increases, the SE of the sleeve will change with the frequency band. The influence of the cuff style on the SE of the sleeve mainly depends on the cuff width and style. The larger the cuff width is, the lower the overall SE of the sleeve is. The more wrinkles there are at the cuff, the better the SE of the sleeve is.

Our results provide a reference for the design, production and evaluation of the sleeve and the whole EMS clothing.

This study explores the impact of owner chief executive officers' (CEO) narcissism on the exporting small to medium-sized enterprises' (SMEs) decision-making on the international market expansion speed after their initial entry. Specifically, the authors use the mechanism of firms' international entrepreneurial orientation (IEO) to examine how owner CEO narcissism may influence SMEs' post-entry speed of internationalization (PSI), both directly and indirectly.

To test the hypotheses, the authors draw on data from a two-wave questionnaire and on archival export data from 291 Chinese exporting SMEs in three municipalities and 17 provinces from 2019 to 2020.

The results support the theoretical predictions that owner CEO narcissism shapes exporting SMEs' decisions on PSI, both directly and indirectly, through the mediation of firm-level IEO.

The study extends emerging research on the role of CEO narcissism in the upper echelons literature into the international marketing (IM) context. It also offers new insights into what drives exporting SMEs' IM decision-making from a psychological microfoundations perspective. Furthermore, the authors theoretically establish and empirically demonstrate the key role of a firm's IEO as a mediator to complement the existing literature's focus on the direct influence of CEO narcissism on firms' internationalization decisions.
