Abstract

Purpose

This study aims to manufacture cotton fabric with thermal regulation performance by using the composite phase change material (CPCM) prepared by coating paraffin doped with expanded graphite (EG), and the thermal effect of the fabric material was evaluated and characterized.

Design/methodology/approach

EG/paraffin CPCM with shape stability and enhanced thermal conductivity were prepared by the impregnation method and then finished on the surface of cotton fabric with coating technology. The microstructure, crystal structure, chemical composition, latent heat property and thermal conductivity were analyzed by scanning electron microscope, x-ray diffraction, Fourier transform infrared spectroscopy, differential scanning calorimeter and thermal constant analyzer. The photo-thermal effect of the coated fabric was studied by a thermal infrared imager.

Findings

CPCM prepared with a mass ratio of EG to paraffin of 1:8 showed excellent shape stability and low paraffin leakage rate. The latent heat of the CPCM was 51.6201 J/g and the thermal conductivity coefficient was increased by 11.4 times compared with the mixed paraffin. After the CPCM was coated on the surface of the cotton fabric, the light-to-heat conversion rate of the C-EG/PA3 sample was improved by 86.32% compared with the original fabric. In addition, the coated fabric showed excellent thermal stability and heat storage performance in the thermal cycling test.

Research limitations/implications

EG can improve the shape stability and thermal conductivity of paraffin but will reduce the latent heat energy.

Practical implications

The method developed provided a simple and practical solution to improving the thermal regulation performance of fabrics.

Originality/value

Combining paraffin wax with fabrics in a composite way is innovative and has certain applicability in improving the thermal properties of fabrics.

Abstract

Purpose

The purpose of this paper is to study enterprise innovation in the perspective of external supplier relationship. On this purpose, this paper examines the impact of supplier change on enterprise innovation with the moderating role of market competition.

Design/methodology/approach

Using 2012–2020 empirical data of Chinese listed manufacturing enterprises, this paper investigates the relationship among supplier change, market competition and enterprise innovation through a two-way interaction model.

Findings

The results show that supplier change has a negative impact on enterprise innovation. And market competition intensifies the negative relationship between supplier change and enterprise innovation. Additional analyses indicate that the main effect and the moderating effect are more significant when the enterprise is non-state-owned or has lower ownership concentration.

Originality/value

This paper studies enterprise innovation from the perspective of external stakeholders. It focuses on supplier relationship in a dynamic variation view, instead of the traditional static ones. Moreover, this paper explores the contingency effect of market competition and gives practical implications for managers to adjust innovation strategy flexibly.

Abstract

Purpose

Influencer marketing is a newer interactive marketing model that has attracted the attention of scholars and marketers. The study aimed to examine the mediation role of influencer credibility (IC) and the moderation role of self-esteem in the effects of individuals' parasocial relationships (PSR) with YouTube influencers on their product attitudes (PATs) and purchase intentions (PIs).

Design/methodology/approach

The researchers used an online survey to test a sequential mediation model and moderation mediation models using Hayes PROCESS modeling.

Findings

The researchers revealed a sequential mediation model that IC and PAT mediate the association between PSR and PI. Individuals who perceived IC to be low were more likely to buy an endorsed product when their self-esteem got lower. When their self-esteem is low, individuals tend to purchase the endorsed products if they have stronger PSR with the influencers. However, they are less likely to buy the endorsed products when their self-esteem gets higher.

Originality/value

The study expands the dimensions of IC. The persuasive power of IC and influencer-user relationship was affected by individual differences, namely, self-esteem. Brands should pay attention to customers' personalities, motivations and preferences when designing strategies to market their products via social media.

Abstract

Purpose

This article will select 25 years of subdivided data to perform Kaplan–Meier survival analysis on the export trade relations of Chinese wooden flooring, use discrete-time cloglog models to analyze influencing factors, use logit and probit models to test the robustness, and try to systematically reveal the duration of China's wood flooring export trade and its influencing factors.

Design/methodology/approach

This study used Kaplan–Meier survival function estimation method. In the survival analysis, survival function and hazard rate function are often used to characterize the distribution of survival time.

Findings

The continuous average export time of China's wooden flooring is relatively long, about 14 years. China's wooden flooring has a negative time dependency. After the export trade exceeds the threshold value of 15 years, the failure rate of trade greatly decreases, which has a “threshold effect.” Gravity model variables have a significant impact on the duration of China's wooden floor export.

Originality/value

Studying the duration of forest products trade is of great significance for clearing deep-level trade relations and promoting sustainable development of forest products trade.

Abstract

Purpose

Influencers’ vlogs have the potential to impact consumer behaviors through vlog-embedded corporate sponsorship and brand collaborations. However, even without brand involvement, vlogs can also “unintentionally” benefit influencers as a relationship-building tool. This study is designed to investigate the relationship between vlog-viewing and audiences’ purchase behaviors of influencer-recommended products through the impacts of influencer–follower interactions, perceived influencer credibility and parasocial relationships.

Design/methodology/approach

An influencer-disseminated online survey was conducted in collaboration with a YouTube celebrity among N = 948 of her 72.6 K subscribers. Statistical analysis was performed through structural equation modeling (SEM) on SPSS Amos.

Findings

SEM results indicated that the extent to which participants liked the vlogs had both a direct impact on their purchase behaviors and secondary impact through social media engagement, parasocial relationships and perceived influencer credibility.

Originality/value

The study expands current research and understanding of influencer marketing. Brands and social media content creators are advised to rethink vlogs as a creative genre for long-term brand–influencer collaborations and implicit social media endorsements.

Abstract

Purpose

This study aims at developing a better understanding of the relationship between network embeddedness and incremental innovation capability and further examines the moderating effect of open innovation.

Design/methodology/approach

This paper adopts hierarchical regressions to validate the theoretical model and collect the patent data of the top 54 firm patentees in the smartphone industry as empirical sample. Using patent citation network data, this paper estimates the relationship between open innovation, network embeddedness and incremental innovation capability.

Findings

This paper empirically shows that structural embeddedness exerts a negative effect on incremental innovation capability, while relational embeddedness is positively related to incremental innovation capability. And open innovation strengthens the relationship between network embeddedness and incremental innovation capability.

Originality/value

This paper shifts the focus of the determinants of incremental innovation capability from internal factors to the external network features by exploring the linkage between network embeddedness and incremental innovation capability. A counterintuitive conclusion is that structural embeddedness shows a negative effect on firm's incremental innovation capability. Furthermore, in contrast to most previous studies, which only focus on the direct effect of open innovation on the firm's incremental innovation capability, our study examines the moderating effect of open innovation on the relationships between network embeddedness and incremental innovation capability. At last, the results provide practical guidance for firms to occupy the beneficial network positions and adopt appropriate open innovation strategies to improve their incremental innovation capability.

Abstract

Purpose

Although many scholars have found that exploration and exploitation innovation have significantly positive effects on firm performance, it remains to be resolved whether the relationship between the two is still established at different stages of enterprise development and in different competitive contexts. This paper aims to clarify the effect of exploration/exploitation innovation on firm performance in start-ups, and in particular, the mediation role of entrepreneurial orientation (EO) and the moderation role of competitive intensity are tested to explore their disturbing effects on above relationship.

Design/methodology/approach

The authors construct a theoretical framework to analyze and verify the relationship between innovation, EO and firm performance. The hypotheses of this paper are put forward by theoretical inference. In addition to test the hypotheses, 143 questionnaires are collected from technology-oriented start-ups in Hefei National University Science Park.

Findings

The empirical results show that consistent with previous findings, exploration innovation and exploitation innovation both have positive impact on firm performance; meanwhile, the EO partially mediates the relationship between both innovations and firm performance. What cannot be ignored is that the competition intensity plays a moderation role between EO and firm performance.

Originality/value

The findings reveal that the impact of innovation activities on corporate performance has been disrupted by EO and competition intensity in start-ups. The work of this paper deepens the understanding of the relationship between innovation, EO, external environment and firm performance, which is of guiding significance to the entrepreneurship management of emerging economies.

Abstract

Purpose

The purpose of this paper is to develop non-leaching and eco-friendly antimicrobial waterborne polyacrylates with excellent antibacterial properties by grafting antibacterial vinyl monomer, glycidyl methacrylate (GMA) modified polyhexamethylene guanidine hydrochloride (PHMG).

Design/methodology/approach

PHMG of different molecular weights were modified by GMA to synthesize antibacterial vinyl monomer, GMA-modified PHMG (GPHMG). Different content and molecular weights of GPHMG were used to synthesize antimicrobial waterborne polyacrylates through emulsion polymerization.

Findings

The addition of GPHMG gained by modifying PHMG showed little influence on thermal stability of the films, but decreased the glass transition temperature(Tg). Meanwhile, the tensile strength decreased, while the breaking elongation increased. The antibacterial properties of the antibacterial films with different GPHMG contents were studied, when GPHMG content was around 0.9 Wt.%, antibacterial films showed excellent antibacterial activity (antibacterial rate >= 99.99 per cent). When weight content of GPHMG in the films remained constant, antibacterial property of films increased first and then decreased with the increase of molecular weight of GPHMG. The structural antibacterial polymer film had more perdurable antibacterial activity than the blended one.

Research limitations/implications

The grafting efficiency of GPHMG to antimicrobial waterborne polyacrylates could be further improved.

Practical implications

Antimicrobial waterborne polyacrylates with excellent antibacterial properties can be used to antibacterial coating and adhesive.

Originality/value

The antibacterial properties of films with different molecular weight of GPHMG were studied, and the durability and stability of antibacterial properties between structural antimicrobial films and blended antimicrobial films were also investigated by ring-diffusion method.

Abstract

Purpose

This research takes the transfer behavior of users from Tencent QQ to WeChat as an example to discuss the wider transfer behavior of social media users on the Internet.

Design/methodology/approach

This paper collects data through a combination of offline interviews and online questionnaire surveys, and utilizes data analysis tools to construct structural equation modeling (SEM). Using Statistical Product and Service Solutions (SPSS) Statistics 22.0 and Analysis of Moment Structures (AMOS) 22.0 software with SEM, this study was carried out to provide reasonable statistical support for relevant proposed hypotheses based on 368 effective samples acquired through the questionnaire.

Findings

The findings of this study show that subjective norm, transfer experience, social communication, and knowledge acquisition all have significant associations with transfer intention and switching behavior. To be specific, transfer intention exerts a positive association on switching behavior; function setting, privacy protection and personal innovation have a favorable association with transfer intention; transfer cost has a significantly negative relationship with transfer intention and switching behavior; function setting has no important relationship on switching behavior.

Originality/value

The research results provide a reference for improving the viscosity and loyalty of social media users in the new era and resolving the problem of user churn.

This study aims to examine whether compensation committees dominated by co-opted directors are less effective in mitigating the CEO horizon problem.

Abstract

Purpose

This study aims to examine whether compensation committees dominated by co-opted directors are less effective in mitigating the CEO horizon problem.

Design/methodology/approach

The author uses a sample of 7,280 firm-year observations from 1998 to 2011.

Findings

In this study, the author finds evidence of opportunistic research and development (R&D) reduction and accruals management in firms with retiring CEOs and compensation committees dominated by co-opted directors. Moreover, it is found that R&D reduction and income-increasing accruals are less discouraged when determining the compensation for retiring CEOs by compensation committees that are dominated by co-opted directors. The results suggest that compensation committees dominated by co-opted directors are less effective in adjusting CEO compensation to mitigate the CEO horizon problem.

Originality/value

The study reveals that co-opted directors are weak monitors. Moreover, the study adds empirical evidence to the debate of organizations’ CEO horizon problem. Finally, the study adds to the literature on corporate governance, revealing that compensation committees play an important role in mitigating an organization’s CEO horizon problem by adjusting CEO compensation.
