Abstract

Purpose

This paper aims to investigate the printability of photocurable PDMS with digital light processing (DLP) in terms of dimensional accuracy, mechanical properties, isotropy and postcure shrinkage.

Design/methodology/approach

The photocurable PDMS was made from methacrylated PDMS-macromer and 2,4,6-Trimethylbenzoyldi-Phenylphosphinate (TPO-L) photoinitiator. The PDMS was printed using different orientations, sizes and post-exposure conditions and then evaluated by tensile test and microscope to determine the printability.

Findings

Printed parts show good accuracy and low shrinkage, but high directionality in modulus, ductility and strength. The dimensional error is less than 2% and the shrinkage rates are less than 0.52%. In contrast, the modulus varies between 0.87 and 0.96 MPa depending on print orientation, elongation varies from 34.7% to 66.4% and strength varies from 0.23 to 0.49 MPa.

Originality/value

This study quantitatively characterizes the printability of photo curable PDMS with DLP, which has not been reported elsewhere. This paper also discusses the challenges of PDMS printing for future advancement.

Abstract

Purpose

Guanxi is the foundation of business success in Chinese and other Eastern cultures, but little is known about the extent to which guanxi influences brand outcomes in channel relationships. The purpose of this study is to propose a novel theoretical framework of interpersonal and interorganizational guanxi relationships in a sales channel context and how these relationships influence brand outcomes.

Design/methodology/approach

The authors conceptualize, develop and validate new scales measuring interpersonal and interorganizational guanxi and test the proposed model with a field study to validate the effects of guanxi on brand loyalty. The causal relationships between interpersonal guanxi and brand attitudes and affect are confirmed in a separate field experiment.

Findings

Findings show that interpersonal guanxi is antecedent to interorganizational guanxi, and these two constructs have significant and differential direct and indirect effects on brand attitudes, brand affect and brand loyalty.

Originality/value

New multidimensional scales measuring both interpersonal and interorganizational guanxi were developed. Both interpersonal and interorganizational guanxi are conceptualized as second-order reflective constructs measured by the reflective first-order guanxi elements of personal and firm trust, personal and firm long-term orientation, xinyong (integrity), reciprocity, interaction and face.

Abstract

Purpose

Despite widespread use of virtual streamers, academic research on this subject remains limited. This study aims to explore the mechanisms by which consumer perceptions of virtual streamers influence consumer purchase intentions.

Design/methodology/approach

We used partial least squares structural equation modeling to analyze validated online survey data from 414 consumers watching virtual streamers.

Findings

Consumer perceptions of virtual streamers (perceived competence, perceived interaction quality and perceived warmth) promote the establishment of transactional psychological contract and relational psychological contract between consumers and virtual streamers, which further affects consumers’ purchase intention.

Originality/value

This study enriches the research on virtual streamers, facilitates their adoption and introduces the psychological contract into a new research context by revealing the formation of the psychological contract from the perspective of virtual streamers. Moreover, this study provides a new understanding of the relationship between disembodied artificial intelligence and consumers.
