Abstract
Purpose
The aim of this paper was to study the initial corrosion behavior of copper in the substations of Zhanjiang and Zhuhai.
Design/methodology/approach
The copper exposed at the substation of Guangdong coastal region in southern China for up to 12 months. The rust layer formed on the copper has been examined by scanning electron microscopy, X-ray energy spectrum, X-ray diffraction and electrochemical polarization techniques.
Findings
The corrosion weight loss of copper at Zhanjiang exposure site is a little more serious than that at Zhuhai exposure site in every exposure period. The corrosion products of copper have different changes in color and composition at the two exposure sites. The tensile strength of copper has a slight decrease after one-year exposure.
Originality/value
The atmospheric exposure experiments of copper in the substations of Zhanjiang and Zhuhai have been adopted for the first time. The corrosion behavior of copper was investigated, and it can provide reference for material selection of the substation.

Abstract
Purpose
Value co-creation is known to increase innovation, but it can backfire under certain conditions. The purpose of this study is to investigate co-creation activities for their effects on consumer perceptions of symbolic designs and to investigate the mediation effect of psychological distance and the moderation effect of peer feedback.
Design/methodology/approach
Three studies were designed by using a survey (Study 1) and two controlled laboratory experiments (Study 2 and 3). Study 1 had a sample size of 160 respondents and examined whether innovative ideas and behavior intensity had different impact on symbolic design. Study 2 had a sample size of 204 respondents and verified the interaction effect between innovativeness and intensity and to show that psychological distance is the underlying internal mechanism. Study 3 examined peer feedback as a critical moderator by using a sample of 235 participants.
Findings
Results show that idea innovativeness positively influences perceptions of symbolic design, while behavior intensity has a negative influence. The studies verify that innovativeness interacts with intensity to affect perceptions of symbolic design. Psychological distance explains why it is difficult to co-create luxury goods. Peer feedback is revealed to be a new moderator.
Originality/value
This research uniquely develops an extensive theory-based conceptual model and highlights two dimensions of value co-creation that interact with product design. The article emphasizes the theoretical and practical importance of studying both direct and indirect moderating effects.

Abstract
Purpose
Existing studies mostly rely on the static characteristics of team members, and there is still a lack of empirical investigation on how entrepreneurial team members make decisions through dynamic team process and how team members’ cognition influences team decision-making. The purpose of this study is to validate how entrepreneurial team heterogeneity affects team decision-making performance from the perspective of dynamic team process.
Design/methodology/approach
Drawing on the theory of input-process-output model, this study proposed and examined the mediating role of team interaction as well as the moderating role of proactive socialization tactics in the relationship between entrepreneurial team heterogeneity and decision-making performance. Based on a sample of 162 entrepreneurial teams that include pairing superiors and subordinates, hierarchical regressions and moderated mediation tests were used to test the hypotheses.
Findings
The research results show that the heterogeneity of entrepreneurial teams is positively correlated with both team interaction and decision-making performance. Team interaction plays a mediating role between entrepreneurial team heterogeneity and decision-making performance; information seeking of proactive socialization tactics moderates the impact of entrepreneurial team heterogeneity on team interaction.
Originality/value
Contributing to the literature on entrepreneurial team decision-making performance, this study identifies that proactive socialization tactics with a high level of information seeking can help entrepreneurial team members respond to environmental and organizational changes more effectively during team development and increase the effectiveness of team interaction. This finding helps us better understand the mechanism and context under which entrepreneurial heterogeneity may enhance the team’s decision-making performance.

Abstract
Purpose
As measurement results of optical gas sensors are constantly affected by the pressure of a target gas, approaches must be taken to modify the results. The purpose of this paper is to compare the traditional measurement method with the new measurement system. At the same time, measurement results of the two systems under different pressures are presented for comparison of the detection performance.
Design/methodology/approach
A theoretical model of line shape function and its impact on the measured results is presented, which is based on direct absorption and wavelength modulation spectroscopy (WMS) for gas concentration detection under different pressures. Methods of linear fitting and result modification have been illustrated and compared. A new testing system with the result modification method used for water vapor concentration detection under different pressures between 1 and 7 atm is applied. With an additional pressure sensor placed in the gas cell and calibration performed, relationships between the amplitude of the second harmonic and concentration of the target gas under different pressures can be obtained.
Findings
Amplitude detection can be used for concentration detection regardless of the change in pressure for the method of direct absorption. Although, WMS with second harmonic detection is not enough. Two methods are presented and compared with WMS under different pressures. Moreover, the result modification method shows better performance as computation is significantly reduced.
Originality/value
The comparison between linear fitting and the result modification method with WMS under different pressures is firstly presented. At the same time, a new testing system with better performance for water vapor concentration detection under different pressures is presented as well.

Abstract
Purpose
Although academics and retail managers share a common belief that crowded stores generate more sales, there is a growing concern about the negative impact of retail crowding on customer relationship management (CRM). This research aims to understand the underlying processes driving the effect, and it explores potential moderators that may mitigate the negative effects on consumer satisfaction.
Design/methodology/approach
This research employs a meta-analysis on retail crowding effects and potential moderators.
Findings
The integrative model of retail crowding reveals that social needs, crowd similarity, crowd expectation and uncertainty avoidance mitigate the negative retail crowding effects on satisfaction.
Research limitations/implications
The authors advance the retailing literature by synthesizing recent studies on retail crowding. The findings also provide a clearer understanding of the mediating role of negative emotions in the relationship between retail crowding and satisfaction.
Practical implications
This research offers guidance for retail managers on how to mitigate the harmful effects of crowding on customer satisfaction.
Originality/value
This research contributes to the retailing literature and offers guidance for retailers on how to mitigate the harmful effects of crowding on cvustomer satisfaction. Our moderation analyses provide insights into how and when crowding drives consumer satisfaction.
