Abstract

Purpose

The purpose of this paper is to study the dynamic behavior of complex-valued switched grey neural network models (SGNMs) with distributed delays when the system parameters and external input are grey numbers.

Design/methodology/approach

Firstly, by using the properties of grey matrix, M-matrix theory and Homeomorphic mapping, the existence and uniqueness of equilibrium point of the SGNMs were discussed. Secondly, by constructing a proper Lyapunov functional and using the average dwell time approach and inequality technique, the robust exponential stability of the SGNMs under restricted switching was studied. Finally, a numerical example is given to verify the effectiveness of the proposed results.

Findings

Sufficient conditions for the existence and uniqueness of equilibrium point of the SGNMs have been established; sufficient conditions for guaranteeing the robust stability of the SGNMs under restricted switching have been obtained.

Originality/value

(1) Different from asymptotic stability, the exponential stability of SGNMs which include grey parameters and distributed time delays will be investigated in this paper, and the exponential convergence rate of the SGNMs can also be obtained; (2) the activation functions, self-feedback coefficients and interconnected matrices are with different forms in different subnetworks; and (3) the results obtained by LMIs approach are complicated, while the proposed sufficient conditions are straightforward, which are conducive to practical applications.

Abstract

Purpose

Currently, consumers can easily access social media to share information and experiences. How a relationship between these consumers influences their decisions has not been clearly investigated. When consumers participate in information sharing activities, they usually communicate with each other and can perceive their social distance from others. Thus, the purpose of this paper is to explore the direct and indirect effects of perceived social distance on eWOM sharing intentions.

Design/methodology/approach

Specifically, a moderated mediation model was validated, in which the indirect effect of perceived social distance on eWOM sharing intentions through reciprocity expectations was moderated by trust.

Findings

Perceived social distance had a positive indirect effect on eWOM sharing intentions through reciprocity expectations, which was found to be negatively moderated by trust.

Originality/value

This study integrates the concept of perceived social distance into the eWOM research area. Moreover, this result adds to the s-commerce literature by specifying the conditions of the indirect effect of perceived social distance through reciprocity expectations on eWOM sharing intention.

Abstract

Purpose

The purpose of this paper is to investigate the impact of corporate social responsibility (CSR) on the performance of service innovation (PSI), and the mediating effect of knowledge acquisition.

Design/methodology/approach

Drawing on social exchange and knowledge management theories, this paper establishes a relevant conceptual model and adopts a hierarchical regression analysis to examine the model with a data set of 298 firms from China.

Findings

CSR positively affects the PSI; however, the effects vary when firms take responsibility for different stakeholders. CSR for the same group of stakeholders influences differently the short-term financial and long-term non-financial PSI, whereas knowledge acquisition mediates the impact of employee and customer CSR on PSI, but not the impact of community CSR on PSI.

Practical implications

Managers could improve the PSI of the firm by strategically assuming CSR and by managing corporate knowledge acquisition activities.

Originality/value

This study contributes to the service innovation literature by identifying the influence of particular types of CSR on PSI, and by highlighting the influencing mechanism of knowledge acquisition. It extends scholarly understanding of the antecedents of PSI as well as the business returns to CSR.

Abstract

Purpose

Social recommender systems have recently gained increasing popularity. The purpose of this paper is to investigate the influences of informational factors on purchase intention in social recommender systems.

Design/methodology/approach

Specifically, this study validated the mediating effect of trust in recommendations and the perceived value between informational factors and consumers’ purchase intention.

Findings

The results confirm that recommendation persuasiveness was a strong predictor of trust in recommendations and perceived value. Recommendation completeness was positively related to trust in recommendations and perceived value as well. Trust in recommendations and perceived value was found to be strong drivers of purchase intention.

Originality/value

The author identifies two sets of informational factors, i.e. recommendation persuasiveness and recommendation completeness, which are relevant to consumer attitudes. The current study proved that informational factors on consumers’ purchase intention are fully mediated through trust in recommendations and perceived value.

The purpose of this study was to develop a new folding method for modeling complicated folded fabric with surfaces of revolution.

Abstract

Purpose

The purpose of this study was to develop a new folding method for modeling complicated folded fabric with surfaces of revolution.

Design/methodology/approach

Irregular wrinkles and mesh distortions easily appear in the fold modeling of a complex curved surface. Aimed at this key technical problem, the segmentation mapping folding method (SMFM) is proposed in this paper. First, high-precision flattened planes were obtained by using segmentation mapping techniques. Second, the segmented planes were transformed into a folded and continuous geometric model by using matrix transformations. Finally, initial stress was used to modify the geometric folding errors, which ensured agreement with the inflated flexible fabric’s geometry and the original design.

Findings

Compared with the traditional folding method, SMFM has the advantages of good finite-element mesh quality, large radial compression rate, regular folds, etc. The surface area error and the volume error of the inflated single torus established by SMFM were only 1.2 per cent, showing that SMFM has high modeling accuracy. The numerical results of an inflatable re-entry vehicle are presented to demonstrate the reliability, feasibility and applicability of SMFM. Moreover, the stress modification reduced the problems of stress concentration and mesh distortions, improving the accuracy and stability of the numerical calculations.

Originality/value

In this paper, for the first time, a folding method for modeling complicated folded fabric is proposed. This methodology can be used to model the multidimensional compression and regular folds of complex surfaces of revolution that cannot be flattened and to improve the accuracy and stability of the numerical calculations.

Abstract

Purpose

Swift guanxi and trust can influence consumers’ decision making in social commerce. What factors will influence the formation of swift guanxi and trust between buyers and sellers in social commerce has not been clearly investigated. The purpose of this paper is to identify antecedents and impacts of swift guanxi and trust in social commerce.

Design/methodology/approach

An online questionnaire was used to collect the data, and Partial Least Squares Structural Equation Modeling was employed for data analysis. Social support and presence are introduced as the antecedents for swift guanxi and trust, leading to the repurchase intention (RI) and social sharing intention of customers.

Findings

The results indicate that social support and presence can influence swift guanxi and trust. Social support and presence are positively associated with swift guanxi and trust which further lead to RI and social sharing intention.

Practical implications

The findings can be used to guide sellers in social commerce platforms to improve their services and make good use of platform features to improve customers’ perception of presence. To attract new customers and retain old customers, sellers should also build swift guanxi and trust through the recommendation and experience sharing of previous buyers on social media.

Originality/value

This study combines social support theory and presence theory to investigate the factors that influence customers’ purchase decision and social sharing intention in the context of social commerce in China. The integration of social support theory and presence theory explains both the social and technical factors that influence swift guanxi and trust in social commerce.

Abstract

Purpose

This study aimed to examine the impact of social influence and personal attitudes on users’ continuance intention. Based on social influence theory, this study developed a theoretical model to explore what factors can influence users’ social network sites continuance intention.

Design/methodology/approach

To validate the research model, the authors used an online survey instrument to gather data. Hypotheses were tested using partial least squares modeling.

Findings

Using a data set including 229 WeChat users in China, the authors found that the influence of subjective norms and group norms on continuance intention is insignificant. Moreover, social identity and personal attitudes were proved to be significant predictors of continuance intention. Specifically, gender played a moderating role in the relationship between social identity and continuance intention. In addition, gender moderated the effect of personal attitudes on continuance intention as well.

Originality/value

This study provided insights into how social influence affects users’ continuance intention. Moreover, this study concentrated on the different impact of social influence and personal attitudes on users’ continuance intention. Specifically, the authors explored gender differences in users’ continuance intention. The results extend the knowledge about the differences of males versus females in using social network sits.

This study aims to investigate the factors and mechanism which influence the doctor’s social and economic benefits from the perspective of social capital.

Abstract

Purpose

This study aims to investigate the factors and mechanism which influence the doctor’s social and economic benefits from the perspective of social capital.

Design/methodology/approach

This paper mainly investigates the factors and mechanism influencing the doctor's social and economic benefits from the perspective of social capital and then constructs a doctor's social capital model and discusses the effects of doctor's social capital on their economic and social benefits; what is more, this paper also considers the moderating effect of patients’ group behavior.

Findings

The results show that the doctor's social capital has a positive and significant effect on doctor's economic benefits, while it has a negative and significant effect on doctors' social benefits. Patients’ group behavior plays an important moderating role; in particular, the number of online patients of doctors can effectively strengthen follow-up patients’ positive perception of the doctor capital, while the number of offline patients has a negative effect on doctors’ economic benefits, but it can reduce its negative impact on doctors’ social benefits by establishing trust between patient and physician.

Originality/value

This paper enriches the relevant research of social capital theory in the medical field and broadens the research about online health care. For platforms, they should give more attention to doctors and their income issues, which is of great significance for their healthy and sustainable development.

This paper compares the work values of the People's Republic of China's (PRC) millennials with their parents.

Abstract

Purpose

This paper compares the work values of the People's Republic of China's (PRC) millennials with their parents.

Design/methodology/approach

The Chinese version of the multidimensional work ethic profile (1. productive use of time; 2. centrality of work; 3. hard work; 4. delay of gratification; 5. leisure; 6. self-reliance; and 7. moral reasoning) was used to survey PRC millennials and their parents. A repeated measures analysis of variance (ANOVA) was used for comparing work values for a subsample of 68 same-gender parent/child dyads. A one-way ANOVA was used for comparing the work values of the total sample of 217 PRC millennials and their parents.

Findings

The repeated measures ANOVA found that one of the seven work values for the male dyads and three of the seven work values for the female dyads were significantly different. The one-way ANOVA found that four of the seven work values for males grouping and five of the seven work values for the females grouping were significantly different.

Research limitations/implications

Social norms and socialization by parents may moderate the influences of changing social conditions on personal values formation predicted by the theory of generations. Researchers need to sample across demographic and socioeconomic subgroups to understand subgroup differences when conducting cross-generational research. Taking large samples, aggregating data and drawing conclusions about cross-generational values may not be a valid approach in trying to understand the complexity of cross-generational values differences.

Practical implications

Managers should be wary of broad declarations about cross-generational values differences. The differences in generational values are nuanced.

Originality/value

This paper shows when controlling for same-gender parents, cross-generational values are very similar. This contrasts other findings on cross-generational values.

Abstract

Purpose

The purpose of this paper is to find optimal reef parameters to minimize the maximum instantaneous opening load for a reefed parachute with geometry and environmental parameters given in the model.

Design/methodology/approach

The dynamic model Drop Test Vehicle Simulation (DTVSim) is used to model the inflation and descent of the reefed parachute system. It is solved by the fourth-order Runge–Kutta method, and the opening load values are thereby obtained. A parallel genetic algorithm (GA) code is developed to optimize the reefed parachute. A penalty scheme is used to have the maximum dynamic pressure restricted within a certain range.

Findings

The simulation results from DTVSim fit well with experimental data from drop tests, showing that the simulator has high accuracy. The one-stage and two-stage reefed parachute systems are optimized by GA and their maximum opening loads are decreased by 43 and 25 per cent, respectively. With the optimal reef parameters, two of the peaks in the opening load curve are almost equal. The velocity, loiter time and flight path angle of the parachute system all change, but these changes have no negative effect on the parachute’s operational performance.

Originality/value

An optimization method for reefed parachute design is proposed for the first time. This methodology can be used in the preliminary design phase for a reefed parachute system and significantly improve design efficiency.
