Abstract

Purpose

This paper aims to examine the antecedent of purchase intention: online seller reputation, product category and surcharge.

Design/methodology/approach

This paper uses five experimental designs to explore the seller reputation, product category and surcharge effects in Internet shopping. The authors chose one seller of low reputation and one seller of high reputation from Yahoo Mall. ANOVA are used to evaluate the results.

Findings

Sellers of high reputation can post higher surcharges to increase the total price paid by the buyer, but sellers of low reputation cannot do so (experiment 1). Moreover, partitioned price will decrease purchase intention for sellers of low reputation more than for sellers of high reputation (experiment 2). Consumers take the longest time to make purchasing decisions when buying credence goods (experiment 3) or buying from sellers of low reputation (experiment 4). The effect of surcharge levied by sellers of low reputation is weakened for consumers with low (vs high) shipping‐charge skepticism (experiment 5).

Practical implications

This study is helpful to online sellers if they can identify their reputation, product category and those consumers who have shipping‐charge skepticism, they can create extra profit through surcharge practice.

Originality/value

The authors’ investigation extends the literature on consumers’ price processing by identifying the important moderators (seller reputation, product category, and elaboration) and probing into the decision process (via the response time). The results suggest prescriptive strategies for online sellers.

Abstract

Purpose

The purpose of this paper is to examine consumer reactions to product categories, online seller reputation, and brand name syllables.

Design/methodology/approach

This paper uses four experimental designs to explore the seller reputation, product category, and brand name syllable effects in internet shopping. The authors chose sellers of (low/high) repute from Yahoo Mall. ANOVA is used to evaluate the results.

Findings

Seller reputation moderates the effect of the brand name syllable level on purchase intention and product category moderates the effect of the brand name syllable level on purchase on internet (experiment 1). Consumers take the longest time to make purchasing decisions when buying credence goods or buying from sellers of low repute and that the response time mediates the moderating role of the product category (experiment 2) or reputation (experiment 3). Moreover, the effect of brand name syllable levels chosen/assigned by sellers of low repute is weakened for consumers with low (vs high) skepticism toward non-store shopping (experiment 4).

Practical implications

This study is helpful to online sellers if they can identify their reputation, product category and those consumers have skepticism, they can create extra profit through brand name syllable practice.

Originality/value

This paper extends the literature on consumers’ brand name syllable processing by identifying important moderators and probing into the decision process. The results allow us to substantiate prior research and suggest prescriptive strategies for internet retailers.

Abstract

Purpose

The purpose of this paper is to explore the role of supervisor gossip in the workplace. This paper proposes a hypothetical model in which supervisor gossip has an effect on leader-member exchange (LMX), in turn resulting in perceived supervisor ostracism among subordinates.

Design/methodology/approach

A dyadic research design was applied to collect data from Taiwanese employees. Supervisors participated in a survey containing measures of supervisor gossip and control variables, whereas subordinates responded to a questionnaire on LMX, perceived supervisor ostracism, and control variables.

Findings

The results indicated that positive supervisor gossip significantly affected LMX. Furthermore, healthy LMX reduced subordinates’ perceptions of supervisor ostracism.

Research limitations/implications

All participants were recruited in Taiwan, which is a limitation for generalising the research findings. Future studies should investigate multiple societies of various cultural profiles.

Practical implications

To improve the quality of the supervisor-subordinate relationship, supervisors should adopt a positive informal communication style, and organisations should provide supervisors with information regarding the implications of workplace gossip, illustrating the substantial benefits of positive gossip and the potential drawbacks of negative gossip.

Originality/value

The present study highlighted the role of supervisor workplace gossip in the field of leadership and empirically investigated the impact of supervisor gossip on subordinates’ reactions.

Abstract

Purpose

This study established and examined a moderated mediation model connecting workplace ostracism with job performance. Drawing from the viewpoint of self-esteem threat, the model posits that the effect of workplace ostracism on job performance is mediated by levels of organization-based self-esteem, while the relationship between workplace ostracism and organization-based self-esteem is moderated by performance goal orientation.

Design/methodology/approach

Multisource data were collected from 160 employees and their immediate supervisors in Taiwan.

Findings

As predicted in the research model, workplace ostracism was found to decrease organization-based self-esteem and, therefore, hinder employees' job performance. Performance goal orientation was found to buffer the negative effect of workplace ostracism on job performance via organization-based self-esteem.

Practical implications

To eliminate the negative impact of workplace ostracism, supervisors can help ostracized employees to self-regulate by aligning their performance goal orientation to reduce the perception of self-esteem threat.

Originality/value

This study provides evidence of boundary conditions for the relationship between workplace ostracism and job performance and explores the impact of self-regulation on ostracized employees' organization-based self-esteem and subsequent job performance.

Abstract

Purpose

This paper aims to review the latest management developments across the globe and pinpoint practical implications from cutting-edge research and case studies.

Design/methodology/approach

This briefing is prepared by an independent writer who adds their own impartial comments and places the articles in context.

Findings

This study examined the link between workplace ostracism and job performance. The study found that workplace ostracism had a direct adverse effect upon performance but was also moderated by both organizational-based self-esteem and performance goal orientation.

Originality/value

The briefing saves busy executives, strategists and researchers hours of reading time by selecting only the very best, most pertinent information and presenting it in a condensed and easy-to-digest format.

Abstract

Purpose

This study aims to enhance the bioavailability and antioxidant function of vitamin E (VE) by combining it with inositol and choline, exploring their synergistic effects and underlying mechanisms.

Design/methodology/approach

An oxidative stress model in mouse hepatocytes was established using hydrogen peroxide to assess the antioxidant effects of combined VE, inositol and choline treatments. Cell viability, the levels of reactive oxygen species (ROS) and malondialdehyde (MDA) and antioxidant enzymes, including superoxide dismutase (SOD) and catalase (CAT), were measured to evaluate protective effects. α-Tocopherol (α-T) and α-tocopherol transfer protein (α-TTP) levels were assessed to determine VE bioavailability. Transcriptome sequencing was conducted to identify gene expression changes and pathways impacted by the treatment.

Findings

An optimal oxidative stress model was established with 641 µM hydrogen peroxide for 6 h. The combination of 20 µM VE, 1.5 mM inositol and 0.3 mM choline significantly improved cell viability, reduced ROS and MDA levels and increased SOD and CAT activities, indicating enhanced antioxidant protection. In addition, α-T and α-TTP levels were higher with this combination, suggesting improved VE bioavailability. Transcriptome analysis revealed that the treatment modulated key pathways linked to inflammation, cancer and lipid metabolism, particularly impacting interleukin-17 and nuclear factor kappa-light-chain-enhancer of activated B cells signaling, cytokine interactions and the alcoholic liver disease pathway.

Originality/value

This study demonstrates a novel approach for improving VE’s bioavailability and effectiveness through its combination with inositol and choline, providing insights that could inform antioxidant therapies and liver health interventions.
