Abstract

Purpose

The purpose of this study is to synthesize a new kind of a cationic-type UV-curing prepolymer diepoxycyclohexylethyl tetramethyldisiloxane, which is used to replace the current prepolymers’ common cycloaliphatic epoxy resins to prepare a novel 3D printing stereolithography material.

Design/methodology/approach

Diepoxycyclohexylethyl tetramethyldisiloxane was characterized and analyzed by FT-IR and 1HMR. Diepoxycyclohexylethyl tetramethyldisiloxane was compounded with a polycaprolactone polyol, some acrylates and photoinitiators to prepare a novel 3D printing stereolithography resin (3DPSLR11). Optical properties of 3DPSLR11 were investigated by HRPL-150A stereolithography apparatus and INITELLI-RAY400 UV-curing system. Tensile mechanical properties of printed 3DPSLR11 specimens were tested by WDW-50-type universal testing machine, and the glass transition temperature (Tg) was determined by DMA. Rectangle plates and double-cantilever parts were fabricated by using the stereolithography apparatus with 3DPSLR11 as the printing material, and the dimension shrinkage factors and the curl factors of the parts were investigated.

Findings

The experimental results showed that the critical exposure (Ec) of the 3D printing 3DPSLR11 was 11.6 mJ/cm2, its penetration depth (Dp) was 0.18 mm, the tensile strength of the cured 3DPSLR11 was 40.1 MPa, the tensile modulus was 1,741.4 MPa, the elongation at break was 15.3%, Tg was 113°C, the dimension shrinkage factor was less than 0.85% and the curl factor was less than 8.00%.

Originality/value

In this work, a novel 3D printing 3DPSLR11 was prepared with diepoxycyclohexylethyl tetramethyldisiloxane as a main prepolymer. The novel 3DPSLR11 possessed excellent photosensitivity, and its cured products had good mechanical and thermal properties. The accuracy and resolution of the fabricated parts were high with 3DPSLR11 for stereolithography in 3D printing, which showed that 3DPSLR11 has potential application value as 3D printing material.

Abstract

Purpose

Building on the territoriality perspective and innovation process theory, to the purpose of this study is to investigate the mechanism of transmission and influence of knowledge territorial behavior congruence on innovation process, which provides theoretical implications for innovative teams to execute territoriality management and create a constructive knowledge sharing climate and platform for sustainable innovation of individuals and organizations.

Design/methodology/approach

The data were collected by the paired method from 311 creative R&D members. In addition, polynomial regressions and response surface method were adopted to test the hypotheses.

Findings

The more congruent the marking behavior and defensive behavior were, the higher the creative idea generation and idea implementation became. The congruence of “high marking high defensive behavior” was more conducive to triggering creative idea generation and promoting idea implementation. Compared with the incongruence of “low marking high defensive behavior,” the incongruence of “high marking low defensive behavior” was more conducive to stimulating creative idea generation. However, there was no significant difference in the incongruence effect of marking defensive behavior on idea implementation. In addition, creative idea generation mediated the relationship between knowledge territorial behavior congruence and idea implementation. Furthermore, team territorial climate moderated the relationship between knowledge territorial behavior congruence and creative idea generation.

Originality/value

The study highlights the theoretical research of territoriality and innovation process. By deconstructing the relationship between the territorial behavior congruence and the innovation process, this study establishes that the congruence and incongruence of the marking defensive behavior in knowledge territoriality exerts different effects on creative idea generation and idea implementation.

Abstract

Purpose

This study aims to explore the transmission mechanism of individual idea generation on team idea implementation and elucidate the relationships among team knowledge territoriality, team information exchange and team trust, which can better improve team knowledge sharing, decrease individual knowledge hiding or territoriality and assist the team in solving the predicament of idea implementation.

Design/methodology/approach

The data were collected by the paired method from 56 Chinese companies’ R&D teams, which comprised 356 valid samples. Besides, structure equitation modeling and hierarchical linear modeling were used to test the hypotheses.

Findings

Team knowledge territoriality had a significant positive impact on individual idea generation, team information exchange and team idea implementation. Team information exchange mediated the relationship between team knowledge territoriality and team idea implementation. Moreover, team information exchange positively moderated the relationship between team knowledge territoriality and individual idea generation. Furthermore, the relationship between individual idea generation and team idea implementation was mediated by team trust.

Originality/value

This study augments the theoretical research of territoriality and innovation process. From the viewpoint of knowledge territoriality to describe the coexistence of knowledge sharing and knowledge hiding in the organization, this study reveals the influence mechanism of team knowledge territoriality on team innovation process. Overall, this study provides empirical support that team territoriality can weaken the adverse impact of individual territoriality on innovation to a certain extent.

Abstract

Purpose

This study aims to explore the dual-path effects of challenge (CTP) and hindrance time pressure (HTP) on knowledge sharing, which provides theoretical reference for knowledge teams to carry out knowledge sharing smoothly.

Design/methodology/approach

This study collected two waves of data and surveyed 416 employees in China. Regression analysis, bootstrapping and structure equitation modeling was adopted to test the hypotheses.

Findings

CTP has a positive impact on employee knowledge sharing, while HTP has a negative impact on employee knowledge sharing. Self-efficacy plays a mediating role between CTP and knowledge sharing, and emotional exhaustion plays a mediating role between HTP and knowledge sharing. The perceived organizational support can moderate the relationship between CTP and self-efficacy and between HTP and emotional exhaustion.

Originality/value

This study explains the reasons for the academic controversy about the effect of time pressure, enhances the scholars’ attention and understanding of the dual-path mechanism between time pressure and knowledge sharing and augments the theoretical research of time pressure and knowledge sharing.

Abstract

Purpose

This study aims to explore the enabling and suppressing effects of leader affiliative and aggressive humor on employee knowledge sharing form the lens of emotional contagion process, which provides theoretical reference for the applications of different leader humor style, thereby enhancing employee knowledge sharing.

Design/methodology/approach

This study collected three waves of data and surveyed 379 employees in China. Regression analysis, bootstrapping and latent moderation structural equation were adopted to test the hypotheses.

Findings

Leader affiliative humor has a positive impact on employee knowledge sharing, whereas leader aggressive humor has a negative impact on employee knowledge sharing. Positive emotion plays a mediating role between leader affiliative humor and employee knowledge sharing, and negative emotion plays a mediating role between leader aggressive humor and employee knowledge sharing. Moreover, supervisor–subordinate Guanxi moderates the relationship between leader affiliative humor and positive emotion, and between leader aggressive humor and negative emotion, respectively.

Originality/value

This study not only adds to the knowledge sharing literature calling for the exploration of antecedents and mechanism of employee knowledge sharing, but also contributes to our comprehensive understanding of the suppressing and enabling effects of leader humor style on employee knowledge sharing. Besides, this study also unpacks the dual-path mechanism and boundary condition between leader humor style and employee knowledge sharing and augments the theoretical explanations of emotional contagion theory between leader humor style and employee knowledge sharing.
