Abstract
Purpose
To meet the requirement of establishing an effective schedule for the assembly process with overall detection and rework, this paper aims to address a new problem named resource-constrained multi-project scheduling problem based on detection and rework (RCMPSP-DR).
Design/methodology/approach
First, to satisfy both online and offline scheduling, a mixed integer programming model is established with a weighted bi-objective minimizing the expected makespan and the solution robustness. Second, an algorithm that combines a tabu search framework with a critical chain-based baseline generation scheme is designed. The tabu search framework focuses on searching for a reasonable resource flow representing the execution sequence of activities, while the critical chain-based baseline generation scheme establishes a buffered baseline schedule by estimating the tradeoff between two aspects of bi-objective.
Findings
The proposed algorithm can get solutions with gaps from −4.45% to 2.33% when compared with those obtained by the commercial MIP solver CPLEX. Moreover, the algorithm outperforms four other algorithms in terms of both objective performance and stability over instances with different weighting parameters, which reveals its effectiveness.
Originality/value
The represented RCMPSP-DR considering the overall detection and rework is an extension of the scheduling problem for large-scale equipment. An effective algorithm is proposed to establish the baseline schedule and determine the execution sequence of activities for the assembly process, which is significant for practical engineering applications.

Abstract
Purpose
Previous studies primarily focus on how to achieve better performance in the international markets, but few centers on whether internationalization is a promising strategy for new ventures’ growth and development. Based on two pioneering frameworks Conservative, Predictable, and Pacemaker (CPP) model and the 7-P model, this paper fills this gap by analyzing how exporting exert heterogeneous effects on two types of growth, sales growth and employment growth. Accordingly, this paper aims to favor market-oriented new ventures to make a strategy on expanding international markets.
Design/methodology/approach
This study is based on firm-level data from the Chinese Industrial Enterprises Database. The year 2005 was used as the shock year. By conducting the propensity score matching method, 793 couples of matched new ventures were collected with sales growth and 686 couples with employment growth. The difference-in-differences method was applied to analyze the various influences that exporting has on new ventures’ sales growth and employment growth.
Findings
The main finding of this paper is that new ventures that exported can achieve better sales growth than their counterparts that only operated domestically, whereas new ventures that remain in the domestic market have no difference in employment growth from those that exported.
Research limitations/implications
This study shows that exporting is especially beneficial for market-seeking new ventures. Because the study is based on Chinese data, scholars of international business can conduct further research on other countries with different economic structures.
Originality/value
Theoretically, this paper contributes to both international business theory and entrepreneurship theory by combining the CPP model and the 7-P model. Practically, this paper shows that exports mainly benefit the sales growth of new ventures. This suggests that business practitioners should consider their growth goals before they choose to enter the global market.

Abstract
Purpose
The purpose of this paper is to investigate the relations between the directors' and officers' (D&O) insurance and digital transformation of Chinese-listed companies to provide insights into triggers of digital transformation from the perspective of D&Os' incentive plan.
Design/methodology/approach
Based on a panel dataset of 2,590 listed manufacturing companies in China from 2017 to 2020, and using a textual analysis of annual reports, this paper empirically examines the impact of D&O insurance on digital transformation. The authors investigate the mechanism through a mediating model and apply a series of robustness tests including firm fixed effect model, propensity score matching and changing key measures.
Findings
The research shows that the digital transformation has been negatively influenced by D&O insurance. The long coverage duration of D&O insurance significantly lowers the level of digital transformation. The moral hazard problem caused by D&O insurance has hampered digital transformation through reducing explorative innovation, while there has been no significant change in innovation quantity. Under the coverage of D&O insurance, firms with worse internal governance and state-owned firms are more reluctant to invest in risky transformation than their counterparts.
Originality/value
Based on a textual analysis of annual reports, this paper empirically tests the influential mechanism of D&O insurance coverage on digital transformation. The authors provide insights into non-tech triggers of digital transformation and uncover how incentive plans influences D&Os' behaviors. This paper provides a new angle to the debate on governance-strengthening and governance-weakening role of D&O insurance.

Abstract
Purpose
The purpose of this paper is to study the relationship between industry risk taking and risk-taking strategy of born-global firms (BGs), and how industry-related variety moderates that relationship.
Design/methodology/approach
The authors apply fixed effect model to analyze 26,499 observations on 10,508 BGs in 276 Chinese cities.
Findings
The authors find that industry risk taking positively influences risk-taking strategy of BGs, and industry-related variety positively moderates such relationship.
Originality/value
The findings reveal how BGs formulate their risk-taking strategy given the dilemma of risk nature and hurdles in firm establishment and rapid internationalization. This paper extends understanding on BGs’ strategy making, supplements the theoretical framework on BGs with an integrated viewpoint containing “regional–industry–firm” levels and contributes to the industry variety argument.

Abstract
Man has been seeking an ideal existence for a very long time. In this existence, justice, love, and peace are no longer words, but actual experiences. How ever, with the American preemptive invasion and occupation of Afghanistan and Iraq and the subsequent prisoner abuse, such an existence seems to be farther and farther away from reality. The purpose of this work is to stop this dangerous trend by promoting justice, love, and peace through a change of the paradigm that is inconsistent with justice, love, and peace. The strong paradigm that created the strong nation like the U.S. and the strong man like George W. Bush have been the culprit, rather than the contributor, of the above three universal ideals. Thus, rather than justice, love, and peace, the strong paradigm resulted in in justice, hatred, and violence. In order to remove these three and related evils, what the world needs in the beginning of the third millenium is the weak paradigm. Through the acceptance of the latter paradigm, the golden mean or middle paradigm can be formulated, which is a synergy of the weak and the strong paradigm. In order to understand properly the meaning of these paradigms, however, some digression appears necessary.

Abstract
We examined the role gender plays in managerial stereotypes and changes that have occurred in the US for executive women in the workforce. We also investigated factors and personality traits that affect advancement into upper management for all executives and those that affect women in particular. Despite increased organisational sensitivity, public policies, and equal rights legislation, women continue to be underrepresented in corporate America. Pay increases and promotions for females have not kept pace with those for men. Study results also indicate that managerial womenwho juggle jobs and family life benefit from these multiple roles, but women who put off marriage and family to build top‐level careers suffer in later years from greatly reduced chances of finding spouses and having children. Further adaptation of organisational culture in the new economy, weakening of the glass ceiling phenomenon, and family friendly work policies may alleviate some of the difficulties experienced by women who want it all.

Abstract
Purpose
Achieving accurate trajectory tracking control of robot manipulators is challenging due to dynamic model errors and uncertain payloads. This paper aims to enhance trajectory tracking performance for robots with n degrees of freedom (DOF).
Design/methodology/approach
This study proposes a robust motion control framework that combines uncertainty and disturbance estimator with model-based compensation. The proposed framework ensures precise trajectory tracking in robot manipulators. In addition, uncertainties in the high-DOF robot dynamics are estimated through a simple model-based compensation for system error dynamics. The stability of the closed-loop system of the proposed framework is analyzed and proved.
Findings
The results indicate that the proposed framework can significantly reduce tracking errors and increase disturbance resistance. The simulation results of a two-link robotic arm verify the effectiveness of the proposed method. The results of the experiments conducted on a seven-DOF torque-controlled Flexiv4S manipulator demonstrate the superior trajectory tracking performance and robustness of the proposed algorithm.
Originality/value
This study introduces a highly efficient, robust motion control framework for high-DOF robots, which can improve the trajectory tracking performance in the presence of model uncertainties.

Abstract
Purpose
Understanding China's economic success requires insights into its peculiar guanxi‐based market. Many scholars are confused about how to apply Western network theories to the guanxi‐based Chinese market. This paper aims to contribute to this comprehensive topic by theoretically exploring the differences among three fundamental network concepts: guanxi; structural hole; and closure.
Design/methodology/approach
Following Heide, the present paper categorises networks into three dimensions: network initiation, network maintenance and network termination, each based on different time phases. The three fundamental network concepts in every dimension are compared, laying out their similarities and dissimilarities in detail.
Findings
Although each of the three networks are initiated either naturally or artificially, guanxi is closely embedded in Chinese institutions. Unlike structural hole and closure, which can be applied at any level, guanxi is a special relation that only exists at the individual level. Structural hole and closure highlight the structures of the networks that bring them various benefits and constraints. Such merits are not evident in guanxi, in which favour exchange plays a crucial role in connecting entities. In addition, guanxi has special rules that affect the strength of ties.
Originality/value
The purpose of this paper is to articulate the differences among guanxi, structural hole and closure. The systematic framework provides a platform to scholars interested in applying the Western network theory to guanxi‐based markets. The study work also provides new insights to non‐Chinese actors doing business in China.
