This paper aims to present a one-shot gesture recognition approach which can be a high-efficient communication channel in human–robot collaboration systems.

This paper applies dynamic time warping (DTW) to align two gesture sequences in temporal domain with a novel frame-wise distance measure which matches local features in spatial domain. Furthermore, a novel and robust bidirectional attention region extraction method is proposed to retain information in both movement and hold phase of a gesture.

The proposed approach is capable of providing efficient one-shot gesture recognition without elaborately designed features. The experiments on a social robot (JiaJia) demonstrate that the proposed approach can be used in a human–robot collaboration system flexibly.

According to previous literature, there are no similar solutions that can achieve an efficient gesture recognition with simple local feature descriptor and combine the advantages of local features with DTW.

The purpose of this research is to review empirical research on customer involvement in innovation and identify future research directions that can better connect this research with marketing strategy literatures and offer opportunities for further theoretical development.

We conduct a review of empirical articles published in eight leading marketing and innovation journals between 2001 and 2017.

The review shows that the literature on customer involvement in innovation is highly diverse and fragmented, lacking a common understanding of what constitutes customer involvement in innovation and its theoretical underpinnings. There exists a multitude of conceptualizations of customer involvement in innovation, which limits effective accumulation of domain knowledge. A large number of studies have taken the customer’s perspective to examine their motivation to participate and ability to contribute, whereas less research has been done from the firm’s perspective to understand how firms may effectively manage the well-recognized challenges of customer involvement as well as the implications of customer involvement for long-term innovation strategy and overall performance. Based on the review, we offer recommendations for future research.

We identify important questions for future research that are highly relevant for the practice of customer involvement in innovation.

We provide a systematic review of the rapidly growing empirical research on customer involvement in innovation. We evaluate key points of differences in the literature and offer a synthesis that helps identify opportunities for future research.

This study aims to test the role of a firm’s marketing and technological capabilities in mediating the relationship between customer involvement in information provision (CIP) and customer involvement in coproduction (CIC) and new product performance, while also investigating the impact of the interactive effect of such capabilities. This investigation is at the firm rather than the project level.

A survey-based questionnaire was distributed to senior managers from 101 Taiwanese electronics firms. The research model and hypotheses were evaluated using partial least squares structural equation modeling in SmartPLS 3.

CIP and CIC improve new product performance indirectly through the development of marketing and technological capabilities. CIP has a stronger positive effect on marketing capabilities than CIC. In addition, the interactive effect of marketing and technological capabilities on new product performance is positive and significant.

The data came from a single respondent in each firm, which may lead to common method bias. In addition, the data were cross-sectional in nature, having been collected at a single point in time. This limits the ability to draw causal inferences, as would be possible with longitudinal data. Finally, the data came from a single industry in only one country.

CIC is useful in terms of product idea generation and screening, as well as in helping to effectively learn and combine market knowledge from customers, whereas CIP takes on a more active role in strengthening marketing capabilities. Managers should understand these direct effects of CIP and CIC, as well as their indirect effects on new product performance.

Previous empirical research is largely limited to project-level implications such as innovativeness, advantages and the financial performance of a specific new product; a clear understanding of the strategic, firm-level implications of CIP and CIC in the context of new product development is lacking. The findings highlight the importance of treating CIP and CIC as continuous processes in a firm rather than viewing each in isolation to a specific project.

This study aims to investigate whether firms purchase directors' and officers' liability (D&O) insurance when the country-level economic policy uncertainty (EPU) is high.

This study uses D&O insurance data from Chinese listed firms between 2003 and 2019 to conduct regression analyses to examine the association between D&O insurance and EPU.

The results show that government EPU, despite being an exogenous factor, increases the likelihood of firms' purchasing D&O insurance, and this effect is more pronounced when firms are exposed to great share price crash risk and high litigation risk, suggesting that firms intend to purchase D&O insurance possibly due to the accentuated stock price crash risk and litigation risk associated with EPU. In addition, the results indicate that the effect of EPU on the D&O insurance purchase decision is moderated by the provincial capital market development and internal control quality.

The study highlights the role of uncertain economic policies in shareholder approval of D&O insurance purchases.

The study enriches the literature on the determinants of D&O insurance purchases by documenting novel evidence that country-level EPU is a key institutional factor shaping firms' decisions to purchase D&O insurance.

The purpose of this paper is to examine whether and how the extent of religion in a firm’s social environment affects corporate innovation and innovation efficiency from the perspectives of religion-related risk aversion and religion-based social norms.

Using a sample of 8,601 Chinese firm-year observations from 2007 to 2012, this paper examines the relationship between religion and innovation intensity, as well as innovation efficiency. A battery of checks, that is, adopting Heckman selection model, using a province-level measure of religiosity and an alternative measure of innovation intensity, and taking the stochastic frontier analysis method to capture corporate innovation efficiency, are conducted to alleviate the concern of self-selection and to guarantee the robustness of the findings of this paper.

This paper finds strong evidence that firms registered in more religious regions, that is, regions with more Buddhist monasteries within a certain radius, undertake fewer innovation activities as measured by the ratio of R&D investment over total sales income but achieve higher innovation efficiency reflected by the value-relevance of R&D investment.

This paper complements the existing literature by suggesting that religion can serve as an informal social mechanism and performs a “less is more” effect in disciplining corporate innovation activities.

Motivated by the significant role of uncertainty in affecting investment decisions and China's economic leadership in Asia, this paper investigates the predictive role of exposure to Chinese economic policy uncertainty at the individual stock level in large Asian markets.

We estimate the monthly uncertainty exposure (beta) for each stock and then employ the portfolio-level sorting analysis to investigate the relationship between the China’s uncertainty exposure and the future returns of major Asian markets over multiple trading horizons. The raw returns of the high-minus-low portfolios are then adjusted using conventional asset pricing models to investigate whether the relationship is explained by common risk factors. Finally, we check the robustness of the portfolio-level results through firm-level Fama and MacBeth (1973) regressions.

Applying portfolio-level sorting analysis, we reveal that exposure to Chinese uncertainty is negatively related to the future returns of large stocks over multiple trading horizons in Japan, Hong Kong and India. We discover this is unexplained by common risk factors, including market, size, value, profitability, investment and momentum, and is robust to the specification of stock-level Fama and MacBeth (1973) regressions.

Our analysis demonstrates the spillover effects of Chinese economic policy uncertainty across the region, provides evidence of China's emerging economic leadership, and offers trading strategies for managing uncertainty risks.

The findings of the study significantly improve our understanding of stock return predictability in Asian markets. Unlike previous studies, our results challenge the leading role of the US by providing a new intra-regional return predictor, namely, China’s uncertainty exposure. These results also evidence the continuing integration of the Asian economy and financial markets. However, contrary findings for some Asian markets point toward certain market-specific features. Compared with market-level research, our analysis provides deeper insights into the performance of individual stocks and is of particular importance to investors and other market participants.

Component positioning is an important part of aircraft assembly, aiming at the problem that it is difficult to accurately fall into the corresponding ball socket for the ball head connected with aircraft component. This study aims to propose a ball head adaptive positioning method based on impedance control.

First, a target impedance model for ball head positioning is constructed, and a reference positioning trajectory is generated online based on the contact force between the ball head and the ball socket. Second, the target impedance parameters were optimized based on the artificial fish swarm algorithm. Third, to improve the robustness of the impedance controller in unknown environments, a controller is designed based on model reference adaptive control (MRAC) theory and an adaptive impedance control model is built in the Simulink environment. Finally, a series of ball head positioning experiments are carried out.

During the positioning of the ball head, the contact force between the ball head and the ball socket is maintained at a low level. After the positioning, the horizontal contact force between the ball head and the socket is less than 2 N. When the position of the contact environment has the same change during ball head positioning, the contact force between the ball head and the ball socket under standard impedance control will increase to 44 N, while the contact force of the ball head and the ball socket under adaptive impedance control will only increase to 19 N.

In this paper, impedance control is used to decouple the force-position relationship of the ball head during positioning, which makes the entire process of ball head positioning complete under low stress conditions. At the same time, by constructing an adaptive impedance controller based on MRAC, the robustness of the positioning system under changes in the contact environment position is greatly improved.

The present chapter addresses a topic that is of growing interest – namely, the exploration of alternative item response theory (IRT) models for noncognitive assessment. Previous research in the assessment of trait emotional intelligence (or “trait emotional self-efficacy”) has been limited to traditional psychometric techniques (e.g., classical test theory) under the notion of a dominance response processes describing the relationship between individuals' latent characteristics and individuals' response selection. The present study, presents the first unfolding IRT modeling effort in the general field of emotional intelligence (EI). We applied the Generalized Graded Unfolding Model (GGUM) in order to evaluate the response process and the item properties on the short form of the trait emotional intelligence questionnaire (TEIQue-SF). A sample of 866 participants completed the English version of the TEIQue-SF. Results suggests that the GGUM has an adequate fit to the data. Furthermore, inspection of the test information and standard error functions revealed that the TEIQue-SF is accurate for low and middle scores on the construct; however several items had low discrimination parameters. Implications for the benefits of unfolding models in the assessment of trait EI are discussed.

Independent directors are important corporate decision participants and makers. Based on the Chinese cultural background, this paper interprets the listing order of independent directors as independent directors’ status, exploring their influence on the corporate research and development (R&D) behavior.

This paper studies A-share listed firms in China from 2008 to 2018 as the sample. The main method is ordinary least square (OLS) regression. We also use other methods to deal with endogenous problems, such as the firm fixed effect method, change model method, two-stage instrumental variable method, and Heckman two-stage method.

(1) Higher independent directors’ status attribute to more effective exertion of supervision and consultation function, and positively enhance the corporate R&D investment. The increase of the independent director’ status by one standard deviation will increase the R&D investment by 4.6%. (2) The above effect is more influential in firms with stronger traditional culture atmosphere, higher information opacity and higher performance volatility. (3) High-status independent directors promote R&D investment by improving the scientificity of R&D evaluation and reducing information asymmetry. (4) The enhancing effect of independent director’ status on R&D investment is positively associated with the firm’s patent output and market value.

This paper contributes to understanding the relationship between the independent directors’ status and their duty execution from an embedded cultural background perspective. The findings of the study enlighten the improvement of corporate governance efficiency and the healthy development of the capital market.
