Abstract

Purpose

Orbital maneuver of the spacecraft can cause large-amplitude vibration of its flexible solar array, which leads to large dynamic stress and a risk of structural failure and fatigue failure. This paper aims to provide a method to reduce such vibration.

Design/methodology/approach

Through controlling the rotation at the root of the solar array, a method of vibration reduction is proposed using zero-placement input shaping technique. Experimental research on a beam scale model of the solar array is performed to verify the effectiveness of the method. Simulation of a detailed example is carried out to investigate whether the method can be applied in engineering.

Findings

The experimental results demonstrate the effectiveness of such method. The simulation results indicate that, by adopting the presented method, the vibration induced by orbital maneuver can be diminished remarkably.

Research limitations/implications

Studies on the robustness of the method are left for further work. Additionally, since only the first-order bending vibration of the flexible solar array is eliminated, further improvements are required such that the stated method can be applied to suppress multi-mode vibration.

Practical implications

An effective method is proposed for spacecraft designers planning to actively suppress the vibration of flexible solar array during the process of orbital maneuver.

Originality/value

This paper fulfils a source of theoretical and experimental studies for orbital maneuver system design and offers practical help for spacecraft designers.

Abstract

Purpose

The purpose of this paper is to investigate the influence of technological creativity for sports and knowledge sharing on individual performance, and to analyze the correlation among creativity for sports technologies, knowledge sharing, and individual performance, via the mediating effect of athletes' self‐efficacy.

Design/methodology/approach

This study selected 250 current athletes, including tennis players, track and field athletes, volleyball players, etc. as the subjects. Statistical methods, such as Cronbach's α, factor analysis, Pearson's correlation, regression analysis, and path analysis, were used to perform analyses.

Findings

It was found that among the technological creativity for sports, athletes' creativity and analytic capacity had significant positive influence on task performance and team performance in athletes' individual performance. In other words, the improvement in athletes' self‐efficacy may improve their creativity and level of technological capacity, which further improves team performance and task performance.

Originality/value

For coaches it is necessary to constantly strengthen athletes' self‐efficacy and provide them with the space for the development of creativity and technological capacity in order to specifically improve their athletic performance. This study integrated relevant theories of technological creativity with those of self‐efficacy to investigate issues regarding improvements in athletes' performance. At present, there is a lack of relevant studies on technological creativity for sports. The research results can serve as a reference to future studies for continuous clarification of investigations into technological creativity for sports.

Abstract

Purpose

The purpose of this paper is to broaden previous work on organizational learning and the factors that influence learning in organizational settings.

Design/methodology/approach

Qualitative and quantitative research methods that included in‐depth interviews and questionnaire distribution were used. Data gathered were analyzed using qualitative analysis along with statistical Pearson correlation and multiple regression analysis.

Findings

Research results indicate that individual motivation to learn, team dynamics, and organization culture practices all have a significant level of influence on organization learning sustainability in non‐profit organizations.

Research limitations/implications

This study provides a better understanding of what influences learning in organizations. The study adds on to existing definitions, theories and concepts and enables another depth of understanding to be explored. A major limitation of this study is its focus on the non‐profit sector and a selected number of organizations thereby limiting its applicability and ability to be generalized.

Practical implications

The findings of the study can help differentiate the learning phenomenon that takes place in organizations. Moreover, non‐profit organizations as well as managers and leaders would be able to better appreciate the learning that takes place in their organizations and create interventions that would enable them to motivate employees to learn effectively, enhance team dynamics, and shape their organization culture to promote their overall learning performance.

Originality/value

More empirical research is needed to better understand the nature of learning in organizations. This research adds to other empirical studies on organization learning while providing a basis for studying the factors that influence an organization's ability to sustain its learning in the long run.

Abstract

Purpose

Experiential marketing is a technique through which companies enhance their promotional marketing with extensive sensory and imagery appeal in order to intensify consumers' experience. The purpose of this current empirical study is to address this strategy and suggests a conceptual framework to explain consumer attitude and behavior toward the promoted brand and the retailer store. Consumers' psychographic characteristics were added to enhance the novelty of the study.

Design/methodology/approach

An experiential stimulating environment was created in a real retail store location. The study employs data collected during the experiential demonstration.

Findings

The path model suggests that the intensity of the experience evokes an affective response toward the promoted brand and an indirect response toward the hosting retailer. Psychographic characteristics, such as the tendency to socialize and extrinsic cues, were found to moderate the effect of experiential marketing.

Practical implications

Product manufacturers and suppliers can use experiential marketing techniques to improve affective and cognitive responses toward their products and brands. Experiential promotion should also be strategically encouraged by retailers because it creates a recreational shopping experience that enhances the retailer's image.

Originality/value

The study is among the few empirical works that examine real-life settings and the double impact of experiential marketing on brand image and the retailer's store image. The study contributes to the existing literature by suggesting a path analysis model toward brand and store images, which combines the effect of experiential marketing with psychographic characteristics.
