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

Fabrics with photothermal conversion functions were developed based on the introduction of shape stable composite phase change materials (CPCMs).

Design/methodology/approach

Acidified single-walled carbon nanotubes (SWCNTs) were selected as support material to prepare CPCMs with n-octadecane to improve the thermal conductivity and shape stability. The CPCMs were finished onto the surface of cotton fabric through the coating and screen-printing method. The chemical properties of CPCMs were characterized by Fourier transform infrared spectrometer, XRD and differential scanning calorimetry (DSC). The shape stability and thermal conductivity were also evaluated. In addition, the photothermal conversion and temperature-regulating performance of the finished fabrics were analyzed.

Findings

When the addition amount of acidified SWCNTs are 14% to the mass of n-octadecane, the best shape stability of CPCMs is obtained. DSC analysis shows that the latent heat energy storage of CPCMs is as high as 183.1 J/g. The thermal conductivity is increased by 84.4% compared with that of n-octadecane. The temperature-regulating fabrics coated with CPCMs have good photothermal conversion properties.

Research limitations/implications

CPCMs with high latent heat properties are applied to the fabric surface through screen printing technology, which not only gives the fabric the photothermal conversion performance but also reflects the design of personalized patterns.

Practical implications

CPCMs and polydimethylsiloxane (PDMS) are mixed to make printing paste and printed cotton fabric with temperature-regulating functional is developed.

Originality/value

SWCNTs and n-octadecane are composited to prepare CPCMs with excellent thermal properties, which can be mixed with PDMS to make printing paste without adding other pastes. The fabric is screen-printed to obtain a personalized pattern and can be given a thermoregulatory function.

Abstract

Purpose

This paper aims to build a theory model to examine the influencing mechanism of entrepreneurial environment on new firm performance based on network view and resource‐based view, and then carry out empirical research.

Design/methodology/approach

Data were obtained from 112 new firms, through the use of questionnaires, in Changchun city, China.

Findings

Evidence indicates that the entrepreneurial environment has an impact on new firm performance through entrepreneurial network and resource acquisition. The results show that eight out of ten hypotheses are supported.

Practical implications

In a hostile, dynamic and complex environment, the new firm should enhance its entrepreneurial network to ensure resource acquisition and then promote performance.

Originality/value

The paper shows definitely the significance of entrepreneurial network as a bridge between external environment and resource acquisition and new firm performance. Entrepreneurial network and resource acquisition are identified as important intermediary variables, and resource combination ability as a moderating variable. This paper examines the influence of external environment on new firm performance. The research has some theoretical and managerial implications for new firms' survival and obtaining growth in highly uncertain and turbulent environments.

Abstract

Purpose

Export manufacturing firms from emerging markets can better meet customer needs by providing customization, which leads to competitive advantages. Although both practice and academic research have deeply discussed customization, the question of whether customization promotes export manufacturing firms' product innovation in the global B2B market is largely unexplored. The purpose of this paper is to address this issue.

Design/methodology/approach

This paper collects survey data from 2,248 export manufacturing firms in China and uses hierarchical moderated regression to explore the relationship between customization and product innovation in the global B2B market and their boundary conditions.

Findings

This research shows that customization positively affects export manufacturing firms' product innovation in the context of the global B2B market, and it shows that internal governance structure (contract governance and relationship governance) and external governance structure (legal enforceability) can be used as boundary conditions that affect the relationship. Specifically, contract governance has an inverted U-shaped moderating effect on the relationship between customization and product innovation; moreover, relationship governance and legal enforceability can strengthen the positive relationship between customization and product innovation.

Originality/value

The study explores the relationship between customization and product innovation in the global B2B market and examines the moderating effect of internal and external governance structures. In addition, the study enriches the research related to customization and product innovation in the context of the global B2B market and provides essential practical insight into the survival of export manufacturing firms from emerging markets.

Abstract

Purpose

This study aims to examine how three types of information technology (IT) capability (supplier technological capability, customer technology-sensing capability and relatedness of IT infrastructure) facilitate knowledge acquisition by the customer when the supplier is dominant in the supplier-customer relationship.

Design/methodology/approach

The unit of analysis was project. The authors designed two different questionnaires that were responded by the project manager of an enterprise resource planning (ERP) software supplier and the contact person of the customer organization in the same project, respectively. The two questionnaires were matched by means of project name. The final sample included a total of 136 projects. The authors used ordinary least squares to test the research hypotheses.

Findings

The authors found that supplier power advantage negatively influenced knowledge acquisition by the customer. The three types of IT capability did not have direct impacts on knowledge acquisition. The moderating effect of customer technology-sensing capability was not significant either. However, supplier technological capability and relatedness of IT infrastructure attenuated the negative effect of supplier power advantage on knowledge acquisition, indicating that both factors promoted knowledge acquisition.

Originality/value

Knowledge acquisition is important for the success of software implementation in the supplier-customer relationship. There is limited evidence in the literature on how to apply externally oriented IT capability to enhance knowledge management, improve knowledge acquisition and manage the business relationship that is typically dominated by the software supplier. The authors provide evidence to examine related issues.

Abstract

Purpose

The purpose of this paper is to explore the transformation from service engagement through hotel consumption behavior to subsequent product purchases and identify marketing strategies to facilitate this transformation.

Design/methodology/approach

Using a 1.5-year data set of transactional data from a typical hotel firm, the authors examined 4,999 valid purchase events via ordinary least squares regression to test the hypotheses proposed.

Findings

Contrary to studies indicating that heavy hospitality users are resistant to external change, the authors found that hotel service engagement (in terms of recency, frequency and monetary value) significantly informed subsequent product purchases. Effects varied based on customized solutions and product purchase channel.

Practical implications

Product managers in hospitality should target customers who have recently patronized hotels as well as hotel customers with high monetary value and frequency. Managers can adopt distinct marketing strategies (e.g. customized solutions and purchase channels) to sell hotel customers more products.

Originality/value

Prior studies have framed the cross-selling of hospitality services as a vital revenue management strategy from hotel firms’ or frontline employees’ perspectives. However, to the best of the authors’ knowledge, this is the first study to test how hotels cross-sell tangible products by targeting customers engaging in hotel consumption and by examining two major product marketing strategies that may facilitate or hinder this cross-selling process.

Abstract

Purpose

Scholars and practitioners have long debated carbon dioxide (CO2) emissions reduction via setting double-carbon goals of peak emissions and carbon neutrality in China. Our study, based on dynamic capability and resource dependence theory (RDT), explores whether digital transformation (DT) affects carbon emissions reduction (CER), and the role of operations and supply chain management (OSCM) factors in this relationship.

Design/methodology/approach

The samples are constructed with 454 A-shared listed manufacturing firms with complete financial data from 2010–2021. Regression models with fixed effects are applied to estimate the potential parameters.

Findings

We find that DT promotes CER. The performance output of CER is strengthened when supplier concentration and customer concentration are high. In contrast, the performance output of CER is weaker when environmental uncertainty is high.

Originality/value

The findings of our study enrich the literature on CER in Chinese manufacturing firms and highlight DT and OSCM factors as important drivers influencing CER practices.

Abstract

Purpose

Based on the business-to-business context in the service industry, this study aims to address two balancing problems that a supplier firm may face in an integrated framework: the trade-off between the two-dimensional market orientations (MO) (i.e. proactive and responsive MO) and the trade-off between two categories of governance mechanisms (i.e. contractual governance [CG] and relational governance [RG]). In doing so, the contingent effects of the governance mechanisms on the relationships between two-dimensional MO and service innovation capability (SIC) are empirically examined and tested.

Design/methodology/approach

A dyadic questionnaire survey of 168 services outsourcing firms’ project managers and strategy managers was used to collect data, which was then used to test the hypotheses by conducting hierarchical regression analysis.

Findings

It was observed that CG weakens the positive relationship between proactive MO (PMO) and SIC, while the positive impact of responsive MO (RMO) on SIC is strengthened. By contrast, RG plays an inverted U-shaped moderating role in the positive relationship between PMO and SIC. Nevertheless, the hypothesis that RG has an inverted U-shaped moderating effect on the effectiveness of RMO is not supported.

Originality/value

Drawing on transaction cost economics and relational exchange theory, this study contributes to the existing literature on MO by revealing how CG and RG differentially shape the value of PMO and RMO.
