Abstract
Purpose
The purpose of this paper is to describe how a traditional metal base plate is replaced with a vapour chamber, a two‐phase flow heat transfer module with high heat transfer efficiency, to effectively reduce the temperature of heat sources as graphic processing unit (GPU) of smaller area and higher power.
Design/methodology/approach
As a first step, the nature of flow field of a vapour chamber‐based thermal module with heat sink is simulated and analysed through computational numerical method. Second, a sample is prepared according to the theoretical results and the performance of thermal modules is tested together with thermal performance experiment.
Findings
The results show that when the fin height from vapour chamber top to fan bottom area is more than 3 mm and not more than 8 mm, the vapour chamber‐based thermal module can achieve the optimum heat dissipation and the maximum heat flux may exceed 90 W/cm2. Also, when copper fins are 3 mm in height, 0.2 mm in thickness, 53 in number and spaced out 1.0 mm apart, the optimum total thermal resistance of a vapour chamber‐based thermal module is 0.28 ○C/W.
Originality/value
The Sapphire Atomic HD3870 of Video Graphics Array module for AMD RV670XT using MicroLoops vapour chamber has greater thermal performance than the AMD reference dual slot thermal module. So, AMD latest GPU is considered to be the vapour chamber thermal cooler to solve the higher power consumption.

Abstract
Purpose
The purpose of this paper is to investigate the influence of store atmosphere on consumers’ positive emotional responses and impulsive purchase behaviour. In addition, it analyses the moderating role of culture characteristics and situational variables on this influence.
Design/methodology/approach
The study carried out a quantitative face-to-face on-site survey of a retail fashion brand in two countries, Brazil and Germany. This paper extended the original model of Jung Chang et al. (2014) based on environment, design and social features (staff) by adding store atmosphere factors such as layout, music and lighting (Mohan et al., 2013), thereby defining store atmosphere as the way customers perceive and experience the combination of all those factors.
Findings
Data analysis from 313 consumers by structural equation modelling (PLS–SEM) showed that most factors influence consumers’ positive emotional responses, but no significant difference between countries. However, the effect of emotions on impulse purchase behaviour is stronger among collectivist consumers (Brazil) than among individualists (Germany).
Originality/value
This study sheds light on the links between store atmosphere and retail market in Brazil and Germany, framing its conclusions in the context of a comparison between cultures. The paper extends the growing research in the area by exploring the moderating role of the individualism–collectivism dimension of national culture in consumer buying behaviour by comparing the strength of various relationships across shoppers from individualistic vs collectivistic cultures.

Abstract
Purpose
We seek to contribute to the literature by comparing and analyzing the relationship between Australian and Taiwanese students regarding environmental value attitude, action intention and green marketing intention. Specifically, by comparing the green marketing intention of hospitality and tourism (H&T) students in the East with that in the West.
Design/methodology/approach
A well-designed curriculum examines student thinking and behavior (learn). This study compares and analyzes the value and attitude and the application of big data to green marketing among Taiwanese and Australian university students using the stimulus-organism-response (S-O-R) model. Structural equation modeling (SEM) was used to test the hypotheses in a sample of 633 H&T students in Taiwan (389) and Australia (244).
Findings
This study also shows how the national differences between Australia and Taiwan have interference effects on the relationship between value attitudes and action intentions and between action intentions and the green marketing intention. We also combined the application of big data and related variables and estimated the mediating effect of related variables to evaluate the impact on action intentions and green marketing of big data applications.
Practical implications
There are significant differences in the sustainable behavior and intentions of H&T higher education students that reflect the educational differences between the East and the West. These different results may be due to a lack of natural resources and the relatively smaller size of Taiwan. With the strengthening of environmental action intention (AI) and green marketing intention (GMI), Taiwanese hospitality and management (H&M) students' sense of crisis increases, and their performance in GMI is slightly higher than that in Australia.
Originality/value
These findings indicate that it is necessary to consider students' ecological concepts, environmental knowledge, environmental value attitude and environmental action intention to improve their intentions to engage in green marketing under the stimulus-organism-response (S-O-R) framework. We also found that environmental knowledge has a mediating effect on the relationship between ecological concepts and environmental value attitude.

Abstract
Purpose
The purpose of this paper is to propose an innovative service model regarding the public library’s pilot project in Taiwan – Borrowing Books from Convenience Stores (BBCS). The proposed model presents a comprehensive evaluation of patrons to enhance readers’ intention to adopt this innovative library service.
Design/methodology/approach
A structured questionnaire was used to collect data from the users of the public library and convenience stores in Taiwan. Structural equation modeling was used to analyze the data.
Findings
The main findings of this study make both theoretical and practical contributions. First, this study explores the library’s extending service to convenience stores, and proposes an integrated BBCS model for the library’s innovative service. Second, the identification of influential factors, such as control influence, social interaction and perceived values of convenience, contributes to a marketing strategy for this innovative service offered by the library. Third, gender differences in some relationships of influential factors on BBCS use intention were identified.
Originality/value
Although many studies have investigated the adoption of self-service technology, this paper is the very first attempt to explore the use of the innovative library service in convenience stores. Based on several theories, an integrated model for users’ intention to use BBCS is proposed in this study. The authors also recommend various gender-specific strategies of BBCS service.

Abstract
Purpose
This paper aims to explore the trends in academic research on elder abuse from 1990 to 2023 using bibliometric analysis. It seeks to identify research trends, hotspots and gaps and proposes future research directions.
Design/methodology/approach
Using bibliometric analysis method, this study analyzes 2,404 documents related to elder abuse from the Scopus database. Visual analysis is conducted using VOSviewer software to reveal research trends, thematic clusters and their interrelationships.
Findings
The study shows a rising concern for elder abuse, especially in nursing homes, domestic settings and among dementia patients. However, research on prevention and intervention measures is lacking, despite increasing international collaboration. Yet, deeper exploration of cross-cultural and regional differences remains limited.
Practical implications
This study reveals that improving care conditions for nursing home residents and dementia patients requires increased funding, professional training for caregivers, the strengthening of regulations and the establishment of clear guidelines for reporting abuse. Additionally, promoting international cooperation, sharing best practices, raising public awareness and supporting ongoing research are essential measures to ensure the safety and dignity of older adults.
Originality/value
To the best of the authors’ knowledge, this study represents the first systematic review of elder abuse research using bibliometric analysis, providing researchers and policymakers with a comprehensive knowledge framework of the field’s development trends and research hotspots.

Abstract
Purpose
During COVID-19 pandemic, the use of social media enhances information exchange at a global level; therefore, customers are more aware and make backup plans to take optimal decisions. This study explores the customer psychology of impulse buying during COVID-19 pandemic.
Design/methodology/approach
The researcher, being a social constructionist, aims at understanding social patterns in impulsive buying strategies during COVID-19 pandemic. Forty UK consumers were participated using the telephonic interview method with the purpose to maintain social distancing practices.
Findings
Results revealed that vulnerable group of people, fear of illness, fear of empty shelves, fear of price increase and social inclination to buy extra for staying at home, increased panic impulsive buying behaviour among customers. Many people socially interpreted the evidence of death rate and empty shelves, which led to more disinformation, rumours and sensationalism, which increased customers' impulsive buying behaviour. Finally, risk of going outside, COVID-19 outbreak among employees of local retail stores, and health professionals' recommendations to stay at home, led to impulsive buying behaviour.
Originality/value
This study has constructed a research framework of customer psychology of impulse buying based on the results of this study and fear and perceived risk theories. The study also explains how the fear of fear, risk perception and conformist tendency enhanced impulsive buying during COVID-19 pandemic. This study has discussed specific implications for retailers.

Abstract
Purpose
Customer co-creation behaviors significantly affect a firm's performance and sustainable growth. This study tested the mediating role of corporate reputation in the relationship between corporate hypocrisy and two types of customer co-creation behaviors: customer citizenship behavior and customer participation behavior. The study also investigated the moderating effect of self-corporate brand connection on the corporate hypocrisy–corporate reputation relationship and the indirect relationship between corporate hypocrisy and customer co-creation behavior through corporate reputation.
Design/methodology/approach
The authors conducted a two-wave research survey with 346 Korean bank customers and tested our hypotheses using PROCESS Macro.
Findings
Corporate reputation mediated the relationship between corporate hypocrisy and customer citizenship/participant behavior. The negative effect of corporate hypocrisy on corporate reputation was more pronounced when self-corporate brand connection was high. Self-corporate brand connection further moderated the indirect effect of corporate hypocrisy on customer citizenship/participant behavior through corporate reputation.
Originality/value
The results clearly explain how corporate hypocrisy affects customer co-creation behavior. This study advances corporate hypocrisy and corporate reputation research by proposing and verifying a moderated mediation model.

Abstract
Purpose
The purpose of this paper is to address the potential impact of need for touch (NFT) on perceived product quality and the possible roles of purchasers’ social (subjective norms), personal (buying impulsiveness) and epistemic (e-commerce orientation) factors, as well as the likely interaction effect of the shopping channel.
Design/methodology/approach
The empirical study is based on 540 observations, analysed in a partial least squares structural equation model.
Findings
The link between the NFT and perceived quality tends to be negative, especially for online purchases. E-commerce orientation reduces the need to touch products, but subjective norms and buying impulsiveness have no significant effects.
Research limitations/implications
The NFT scale might be improved by adding more items. Some of the structural model coefficients indicate a low effect size. Finally, the results are limited to Spanish purchasers of the focal product.
Practical implications
Firms should appeal to purchasers’ e-commerce orientation to reduce the negative implications of a need to touch products among consumers shopping online.
Originality/value
The need to touch a product may be an obstacle to online purchases, yet few studies deal with its impact in online, relative to offline, contexts to evaluate product quality. This study also integrates personal, social and epistemic factors.

Abstract
Purpose
The purpose of this paper is to develop a small data set forecasting method to improve the effectiveness when making managerial decisions.
Design/methodology/approach
In the grey modeling process, appropriate background values are one of the key factors in determining forecasting accuracy. In this paper, grey compensation terms are developed to make more appropriate background values to further improve the forecasting accuracy of grey models.
Findings
In the experiment, three real cases were used to validate the effectiveness of the proposed method. The experimental results show that the proposed method can improve the accuracy of grey predictions. The results further indicate that background values determined by the proposed compensation terms can improve the accuracy of grey model in the three cases.
Originality/value
Previous studies determine appropriate background values within the limitation of traditional grey modeling process, while this study makes new background values without the limitation. The experimental results would encourage researchers to develop more accuracy grey models without the limitation when determining background values.

Abstract
Purpose
Guided by the Stimulus-Organism-Response (S-O-R) model, this study aimed to investigate direct and indirect effects of apparel store environmental characteristics and consumers' positive emotional responses to the environment on impulse buying behavior. Also, this study sought to examine how situational variables interact with consumers' positive emotional responses in influencing impulse buying behavior.
Design/methodology/approach
Survey data were collected using a store intercept method from 118 female consumers of an outdoor retail store in the western region of the USA.
Findings
The study found direct effects of ambient/design characteristics on consumers' positive emotional responses and direct effects of consumers' positive emotional responses to the retail environment on impulse buying behavior. Money availability and task definition moderated the relationship between consumers' positive emotional responses and impulse buying behavior.
Research limitations/implications
The conceptualization of a theoretical framework of impulse buying behavior for apparel resulted from this study.
Practical implications
Managing appealing store design characteristics may increase consumers' positive emotions and impulse purchases. Displays designed to attract impulse purchasers should target browsers without restricted budgets.
Originality/value
This study expands the application of the S-O-R model in the context of apparel by including situational factors as moderating variables.
