Abstract
Purpose
The purpose of this study which resulted in this work is to propose an optimization method of sensors distribution for structural impact localization.
Design/methodology/approach
This paper presents a multi-objective optimization study of a novel sensors distribution technique, where two optimization objective functions are considered: sensors number and sensors location optimization performance index. In addition, the finite element analysis, the time-frequency transform and the principal component analysis are combined to quantize the above objective functions. The non-dominated sorting genetic algorithm II (NSGA-II) is used to acquire Pareto solutions.
Findings
The effectiveness of this method is validated through a prototype laboratory called the piezoelectric intelligent structure where promising results are obtained.
Originality/value
An optimization method of this novel sensors distribution technique is built and produced a set of efficiency solutions for the real-world problem of impact localization where two conflicting objectives are involved.

Abstract
Purpose
Although knowledge has become a decisive factor in the development of firms, there has been no detailed investigation into how start-ups acquire external knowledge. In order to narrow the research gap, this paper attempts to explore the mechanism of acquiring external knowledge in start-ups from the perspective of “environment–[sic.] structure” interaction.
Design/methodology/approach
This research develops a conceptual model regarding improvisation as an independent variable, strategic flexibility as a mediator, knowledge acquisition as the dependent variable and environmental mutation as a moderator between improvisation and strategic flexibility. Furthermore, this study collects the survey data from 277 firms and uses structural equation modeling (SEM) to empirically test the model and hypotheses.
Findings
The results show that creativity-bricolage and spontaneity-persistence have significantly positive effects on both capability flexibility and coordination flexibility. However, the positive effects of pressure-stress on capability flexibility and coordination flexibility are not supported. Meanwhile, the mediating roles of capability flexibility and coordination flexibility are supported. Finally, environmental mutation only positively moderates the relationship between creativity-bricolage and capability flexibility.
Originality/value
Improvisation can be seen as a core antecedent for start-ups to acquire external knowledge in environmental mutation. More specifically, the significant mediator is strategic flexibility to promote the relationship between improvisation and knowledge acquisition. The findings provide practical inspiration for start-ups to effectively utilize improvisation in emergencies.

Abstract
Purpose
The purpose of this paper is to investigate the role of intrinsic motivation and self-construal in explaining the relationship between work-related identity discrepancy and employee innovation behavior.
Design/methodology/approach
Based on a survey of 637 respondents from 15 organizations in southern China, this study examines four hypotheses with regard to the relationship between work-related identity discrepancy and employee innovation behavior through hierarchical regression analysis.
Findings
The research results indicate that work-related identity discrepancy is negatively related to employee innovation behavior, but intrinsic motivation mediates their negative relationship, and self-construal moderates this mediating effect further. Specifically, the results demonstrate that perceiving work-related identity discrepancy can lower intrinsic motivation among employees with interdependent self-construal and subsequently reduce their innovation behavior.
Originality/value
Drawn on social cognitive theory, this study reveals the negative effect of work-related identity discrepancy on employee innovation behavior and the moderated mediation effect of intrinsic motivation and self-construal on the negative relationship. The finding expands existing literature on work-related identity discrepancy and employee innovation behavior.

Abstract
Purpose
Under extensive pressure from normal market competition, frequent technological change and extreme exogenous shock, firms are facing severe challenge nowadays. How to withstand discontinuous crises and respond to normal risks through improving resilience (RE) is an important question worth researching. Thus, drawing on the strategic entrepreneurship theory, the purpose of this study is exploring the relationship between entrepreneurial orientation (EO) and RE, and combining digitization to discuss the role of digital business capability (DBC), digital business model innovation (DBMI) and environmental hostility (EH).
Design/methodology/approach
Based on survey data from 203 Chinese firms, using the methods of linear regression and bootstrap to test our hypothesis. Furthermore, fuzzy-set qualitative comparative analysis (FsQCA) is used to identify previously unknown combinations which lead to strong/weak RE in digital context.
Findings
First, EO positively influenced DBC and RE. Second, DBMI promoted RE, DBC and DBMI served as sequential mediators that linked EO and RE. Third, EH positively moderated the effects of EO on RE. Further the study revealed that different configuration of DBMI and dimensions of EO and DBC can explain RE.
Originality/value
The study explains mechanism of RE from perspective of digitization. The conclusion is good for further consolidating strategic entrepreneurship theory, and providing a new frame for firms to build the ability of antifragile.

Abstract
Purpose
Propose a more comprehensive explanation on the determinants and fluctuations of China’s exchange rate policy in the past decade (2005–2015).
Approach
Case study on China’s exchange rate policies in three respective stages since 2005 and then a comparative study on these three stages.
Findings
Put forward a two-pronged explanation on the determinants and fluctuations of China’s exchange rate policy in the past decade and arrive at three specific conclusions. First, external pressure is only one factor among many influencing the formation of China’s national interests (Guojia Liyi in Chinese) and the decision-making process on exchange rate policy. Second, national interest is the fundamental driving force and substratum for making China’s exchange rate policy. Third, in the short term, the specific exchange rate policies in different periods were not always in accordance to the national interests (or Guojia Liyi), due to the influences of some factors on the decision-making environment.
Value
The comprehensive view is conducive to better explaining the formation and fluctuations of China’s exchange rate policy and consequently contributes to understanding and even predicting future policies.

Abstract
Purpose
China after 1949, especially since entering the 21st century, significant progress has been made in leadership research under Chinese context. However, so far there has been no systematic review and prospect of China's leadership research in the past 70 years. Therefore, with the help of scientific visualization software Citespace, this paper analyzes the research papers on leadership in the context of China from the top international journals of management science and applied psychology (1949–2018), supplemented and verified the previous research conclusions based on qualitative review, and quantitatively demonstrated the research evolution of leadership field.
Design Methodology Approach
Using a scientific visualization tool CiteSpace and 145 international leadership works, which were published in 64 top international journals and collected from the Web of Science database, and 852 domestic works which were published in 28 top domestic journals and collected from the CNKI database from 1949 to 2018, we draws keyword co-occurrence knowledge graph and keyword strategy map to visualize the landscape and evolution of leadership research and analyze the hot topics and research trends in the field of leadership.
Findings
The research found that: (1) Before 2002, there were only 7 articles published in 64 international top journal, mainly focusing on Western leadership theories such as transformational, cross-cultural comparison and the adaptability in Chinese context; (2) From 2003 to 2012, scholars had begun to introduce mainstream quantitative research paradigm in international academic community; (3) From 2013 to 2018, researches tended to be synchronized, with 461 and 99 papers published respectively. How emerging leaderships (such as ethical leadership) affect on various emerging outcome variables (such as creativity, voice behavior, unethical pro-organizational behavior etc.) is hot topic for future research.
Originality Value
Different from the previous qualitative reviews on organizational culture research, this paper, for the first time, uses bibliometric research methods to systematically analyze the evolution path of leadership research during the 70 years of China(1949–2018, and puts forward the future research prospects.

Abstract
Purpose
This study, a narrative literature review, aims to examine the combined benefits of the active and passive use of social media (SM) for well-being (WB), physical and mental health during the COVID-19 pandemic.
Design/methodology/approach
A search strategy has been carried out in the databases: Riss, PubMed, Medline, Scopus and Google Scholar, including all the articles published until 19 October 2023.
Findings
SM offers various benefits, including global risk awareness, health information, social connections and support. With the natural increase in physical inactivity due to COVID-19 social restrictions, SM has been identified as an appropriate tool for promoting physical activity (PA) at home to improve health.
Research limitations/implications
It suggests that the combined use of active and passive benefits of SM could potentially play an important role in public health by increasing individuals’ health behaviours. In addition, dissemination, sharing and social interaction of information provided by YouTube can encourage healthy behaviours, contribute to WB, physical and mental health and raise public health awareness.
Originality/value
The findings presented in this study highlight the combined benefits of differentiating the features of SM use. Compared to other SM platforms, YouTube can be used as a useful tool for home-based PA that promotes health by enabling people to remain active and avoid barriers to PA due to social restrictions during the global crisis. In addition, some recommendations from the findings may help protect against potential risks and improve public health outcomes during global crises, such as the COVID-19 pandemic, among the general public using SM.

Abstract
Purpose
The purpose of this paper is to study the users’ willingness for acceptance of background music service in university libraries based on intelligent campus and to improve the intelligence level of university libraries and provide a reference for the atmosphere.
Design/methodology/approach
The research method of combining theory with practice is applied, and field distribution method and network survey method are used. An algorithm model is established to investigate relevant users, and statistical analysis of the data obtained is made.
Findings
The results show that in the questionnaire survey, girls are more inclined to study in the environment of library than boys; for grade, sophomores and juniors are more inclined to go to library than other grades; through model analysis, the target users are more inclined to choose light music as background music, accounting for 65 percent. Heavy metals and other users have fewer choices, accounting for only 8 percent.
Research limitations/implications
This questionnaire is mainly filled out in paper form on site, so it only selects some nearby students as the survey objects. However, the condition of university libraries across the country must be different due to regional differences, disciplinary differences and funding differences, so the representative sample may be insufficient. Therefore, in the follow-up research, the scope of the survey should be expanded, especially the geographical scope. It should collect as much data as possible for students of different types and genders, so as to expand the applicable scope and explanatory power of the model.
Practical implications
Starting from the library scene, this research studies the acceptance intention of users of background music service in the library, which provides reference for the improvement of the intellectualization of university libraries and their atmosphere. Although different university libraries have different operation modes and service characteristics, the conclusions of this study have certain practical significance for the library industry because the library industry has many commonalities.
Originality/value
At present, the research on the background music service of University Library based on the smart campus is relatively rare and limited to the theoretical stage. Few people have deeply explored the background music service of the library, and no scholars have quantitatively studied it. In this study, based on the questionnaire and from the perspective of users, the acceptance intention of background music service users is investigated, which provides a reference for the improvement of the intellectualization of university libraries and its atmosphere. It is a research topic of great practical significance.

Abstract
Purpose
The purpose of this paper is to explore the relationship between top management team (TMT) internal social capital and strategic decision-making speed, and further explore role of TMT behavioral integration in their relationship. It reveals how TMT internal social capital impacts strategic decision-making speed.
Design/methodology/approach
On the basis of the social capital theory and upper echelons theory, at first, a model about TMT internal social capital and strategic decision-making speed is proposed by exploratory case study. Then, the data obtained via questionnaire from 67 TMTs by software SPSS 19.0 and AMOS 17.0 are analyzed, and the theoretical hypotheses as mentioned above are verified.
Findings
The empirical study found that different dimensions of TMT internal social capital have significant positive impact on TMT behavioral integrity; TMT behavioral integrity has significant positive impact on strategic decision-making speed; and TMT behavioral integrity as an intermediary variable played a brokering role in the relationship between TMT internal social capital and strategic decision-making speed.
Originality/value
The study enriches the empirical test on the relationship between TMT internal social capital and decision speed, thereby helping the authors further understand how to improve the speed of strategic decision making in TMT.
