Abstract

Purpose

The purpose of this paper is to explicate the influence of diverse team on team-level ambidexterity and its curvilinear assessment, and test the mediating role of team reflexivity and the moderating role of shared meta-knowledge in the curvilinear relationship between team diversity and team ambidexterity.

Design/methodology/approach

The authors collected multisource and temporally separated data on 206 R&D teams within 28 high-tech firms in Taiwan.

Findings

This study found a complex, curvilinear, moderated mediation relationship that functional background diversity has with team ambidexterity. Furthermore, consistent with the notion from categorization-elaboration model, the authors found the curvilinear relationship that functional background diversity has with both team ambidexterity and team reflexivity. Finally, the authors also found that the curvilinear relationship between functional background diversity and team reflexivity was moderated by shared meta-knowledge, such that the positive relationship was strengthened and the negative relationship weakened, in higher shared meta-knowledge in teams rather than lower.

Originality/value

The results demonstrate that team diversity-team ambidexterity relationship is much more complicated than previous works have assumed or suggested. Overall, the authors contribute to a novel understanding about the importance of team diversity in ambidextrous teams by opening the black box of how and when functional background diversity and team ambidexterity.

Abstract

Purpose

The purpose of this paper is to test how team regulatory focus may relate to individual creativity and team innovation; and address the fit/misfit issue of team regulatory focus and team bureaucracy.

Design/methodology/approach

The authors collected data from 377 members and their leaders within 56 R&D teams in two Taiwanese companies.

Findings

A team promotion focus was positively related, whereas a team prevention focus was negatively related, to both team innovation and member creativity through team perspective taking and employee information elaboration, respectively. Furthermore, team bureaucracy played a moderating role that suppressed the indirect relationship between team regulatory focus and creativity.

Originality/value

This is one of first studies to explore an underlying mechanism linking team regulatory focus and both team innovation and member creativity. The authors provide a more complete view of the creative and innovation implications of team-level self-regulation.

Abstract

Purpose

This research adopts a dynamic self-regulation framework to test whether there is a curvilinear relationship between creative self-efficacy and individual creative performance at the within-person level. Furthermore, to establish a boundary condition of the predicted relationship, the authors build a cross-level model and examine how approach motivation and avoidance motivation moderate the complex relationship between creative self-efficacy and individual creative performance.

Design/methodology/approach

To obtain results from a within-person analysis, the authors collect multi-source data from 125 technicians who provided monthly reports over an 8-month period.

Findings

The authors find evidence of an inverted U-shaped relationship between creative self-efficacy and individual creative performance at the within-person level and differential moderating effects of approach/avoidance motivations.

Originality/value

This study is one of the first to challenge the assumption that creative self-efficacy always has a positive linear relationship with creativity. It provides a more complete view of the complex pattern between creative self-efficacy and creativity at the within-person level.

The purpose of this paper is to test a multilevel framework to further explicate how team leaders’ authentic leadership is related to their followers’ individual creativity.

Abstract

Purpose

The purpose of this paper is to test a multilevel framework to further explicate how team leaders’ authentic leadership is related to their followers’ individual creativity.

Design/methodology/approach

This study is based on a questionnaire survey/analysis of analyses of multisource and lagged data from 63 team leaders and 428 followers in Taiwan.

Findings

The findings demonstrated that leader-member exchange (LMX) and team psychological safe climate mediated the positive relationship of authentic leadership on followers thriving at work. Furthermore, employee thriving at work sequentially mediated the positive relationship between authentic leadership and employee creativity. The author also found that indirect relationship of LMX with employee creativity through thriving at work was stronger when authentic leadership was higher.

Originality/value

The authors contribute to the existing understanding that authentic leadership relates to individual creativity through three multilevel mechanisms: leaders modeling their authenticity to develop and maintain their dyad-level exchange relationships with their followers (LMX), motivating the team, captured by team-level psychological safe climate and its members, reflected by employee-level thriving at work, and facilitating the relationship between LMX and employee thriving at work.

Abstract

Purpose

This study aims to investigate how consumers respond to global brands adapting to local elements. Specifically, this study identified three factors (i.e., cultural compatibility, cultural elements authenticity and cultural pride) affecting the purchase intentions (PIs) toward global brands using Chinese elements among Chinese consumers in China and Chinese immigrants in North America. Another aim is to examine the moderating role of acculturation in the relationship between cultural pride and PIs among Chinese immigrants.

Design/methodology/approach

Three studies were conducted to test the hypotheses in China and North America. Confirmatory factor analysis was used to confirm the factor structure. Hierarchical regression was used to test the main effects and moderated regression analysis was used to test the moderation effect.

Findings

Results show that cultural compatibility, cultural elements authenticity (CEA) and cultural pride positively affect the PIs toward global brands with Chinese elements for both Chinese consumers and Chinese immigrants. Further, among Chinese immigrants, acculturation moderates the relationship between cultural pride and PIs.

Originality/value

This study explored the factors influencing the PIs toward global brands using Chinese elements, filling a research gap. To the best of the authors’ knowledge, this study is the first to examine how perceived CEA affects consumers’ PIs toward global brands with Chinese elements. Further, the findings have implications for global brands that want to target Chinese consumers and Chinese immigrants in overseas markets.

Abstract

Purpose

This paper aims to fabricate inclined thin-walled components using positional wire and arc additive manufacturing (WAAM) and investigate the heat transfer characteristics of inclined thin-walled parts via finite element analysis method.

Design/methodology/approach

An inclined thin-walled part is fabricated in gas metal arc (GMA)-based additive manufacturing using a positional deposition approach in which the torch is set to be inclined with respect to the substrate surface. A three-dimensional finite element model is established to simulate the thermal process of the inclined component based on a general Goldak double ellipsoidal heat source and a combined heat dissipation model. Verification tests are performed based on thermal cycles of locations on the substrate and the molten pool size.

Findings

The simulated results are in agreement with experimental tests. It is shown that the dwell time between two adjacent layers greatly influences the number of the re-melting layers. The temperature distribution on both sides of the substrate is asymmetric, and the temperature peaks and temperature gradients of points in the same distance from the first deposition layer are different. Along the deposition path, the temperature distribution of the previous layer has a significant influence on the heat dissipation condition of the next layer.

Originality/value

The established finite element model is helpful to simulate and understand the heat transfer process of geometrical thin-walled components in WAAM.

Abstract

Purpose

This paper aims to study the residual stress of deposited components which is a main issue to impede the widespread application of wire and arc additive manufacturing (WAAM). The interlayer dwell time is believed to have an effect on residual stress distributions in WAAM due to variance in heat dissipation condition. A coupled thermomechanical finite element model was established to evaluate the role of dwell time in between layers on the mechanical behavior of thin-walled components in WAAM, mainly involving thermal stress evolutions and residual stress distributions of the component and substrate.

Design/methodology/approach

Four interlayer dwell times including 0, 120 and 300 s and cooling to ambient temperature were selected in finite element modeling, and corresponding experiments were conducted to verify the reliability of the model.

Findings

The results show that with the interlayer dwell time, the stress cycling curves become more uniform and the interlayer stress-releasing effect is weakened. The residual stress levels on the substrate decrease with the increasing interlayer dwell time. In the outside surface of the component, the distributions of axial and longitudinal residual stress along the deposition path are the smoothest when the interlayer dwell time is cooling to ambient temperature. In the inside surface, a longer interlayer dwell time leads to an obvious decrease in the longitudinal and axial residual stress along the deposition path.

Originality/value

The comprehensive study of how the interlayer dwell time influences stress field of components is helpful to improve the deposition defects generated by WAAM.

Abstract

Purpose

An accurate prediction of process-induced residual stress is necessary to prevent large distortion and cracks in gas metal arc (GMA)-based additive manufactured parts, especially thin-walled parts. The purpose of this study is to present an investigation into predicting the residual stress distributions of a thin-walled component with geometrical features.

Design/methodology/approach

A coupled thermo-mechanical finite element model considering a general Goldak double ellipsoidal heat source is built for a thin-walled component with geometrical features. To confirm the accuracy of the model, corresponding experiments are performed using a positional deposition method in which the torch is tilted from the normal direction of the substrate. During the experiment, the thermal cycle curves of locations on the substrate are obtained by thermocouples. The residual stresses on the substrate and part are measured using X-ray diffraction. The validated model is used to investigate the thermal stress evolution and residual stress distributions of the substrate and part.

Findings

Decent agreements are achieved after comparing the experimental and simulated results. It is shown that the geometrical feature of the part gives rise to an asymmetrical transversal residual stress distribution on the substrate surface, while it has a minimal influence on the longitudinal residual stress distribution. The residual stress distributions of the part are spatially uneven. The longitudinal tensile residual stress is the prominent residual stress in the central area of the component. Large wall-growth tensile residual stresses, which may cause delamination, appear at both ends of the component and the substrate–component interfaces.

Originality/value

The predicted residual stress distributions of the thin-walled part with geometrical features are helpful to understand the influence of geometry on the thermo-mechanical behavior in GMA-based additive manufacturing.

Abstract

Purpose

The purpose of this study is to present how the thermal energy transmission of circular parts produced in robotized gas metal arc (GMA)-based additive manufacturing was affected by the substrate shape through finite element analysis, including distributions of thermal energy and temperature gradient in the molten pool and deposited layers.

Design/methodology/approach

Three geometric shapes, namely, square, rectangle and round were chosen in simulation, and validation tests were carried out by corresponding experiments.

Findings

The thermal energy conduction ability of the deposited layers is the best on the round substrate and the worst on the rectangular substrate. The axial maximum temperature gradients in the molten pool along the deposition path with the round substrate are the largest during the deposition process. At the deposition ending moment, the circumferential temperature gradients of all layers with the round substrate are the largest. A large temperature gradient usually stands for a good heat conduction condition. Altogether, the round substrate is more suitable for the fabrication of circular thin-walled parts.

Originality/value

The predicted thermal distributions of the circular thin-walled part with various substrate shapes are helpful to understand the influence of substrate shape on the thermal energy transmission behavior in GMA-based additive manufacturing.

Abstract

Purpose

This paper aims to study different possibilities for implementing easy-to-use and cost-effective micro-systems to detect and trace expelled gases from rotten food. The paper covers various radio-frequency identification (RFID) technologies and gas sensors as the two promoting feasibilities for the tracing of packaged food. Monitoring and maintaining quality and safety of food in transport and storage from producer to consumer are the most important concerns in food industry. Many toxin gases, even in parts per billion ranges, are produced from corrupted and rotten food and can endanger the consumers’ health. To overcome the issues, intelligent traceability of food products, specifically the packaged ones, in terms of temperature, humidity, atmospheric conditions, etc., has been paid attention to by many researchers.

Design/methodology/approach

Food poisoning is a serious problem that affects thousands of people every year. Poisoning food must be recognized early to prevent a serious health problem.

Contaminated food is usually detectable by odor. A small gas sensors and low-cost tailored to the type of food packaging and a communication device for transmitting alarm output to the consumer are key factors in achieving intelligent packaging.

Findings

Conducting polymer composite, intrinsically conducting polymer and metal oxide conductivity gas sensors, metal–oxide–semiconductor field-effect transistor (MOSFET) gas sensors offer excellent discrimination and lead the way for a new generation of “smart sensors” which will mould the future commercial markets for gas sensors.

Originality/value

Small size, low power consumption, short response time, wide operating temperature, high efficiency and small area are most important features of introduced system for using in package food.
