Abstract
The effect of the tube wall heat conduction on the natural convection in a tilted long cylindrical envelope with constant, but different temperature of the two ends and an adiabatic outer surface was numerically investigated. The envelope is supposed to be a simplified model for the pulse tube in a pulse tube refrigerator when the pulse tube is positioned at different orientations. It is found that the cylindrical envelope lateral wall heat conduction can enhance the heat transfer from the hot end to the cold end, not only because of the increase in pure heat conduction in the wall, but more importantly, also the intensification of the natural convection within the enclosure. This enhancement is resulted from the big temperature difference between the tube wall and the adjacent fluid near the hot and cold ends. Adoption of low thermal conductivity tube can effectively reduce such additional heat transfers from hot to cold end, thus reducing the loss of cooling capacity for the pulse tube refrigerator.

Abstract
Purpose
The purpose of this paper is to focus on the condensation process of hot vapor on smooth/rough walls and find how the condensation film forms and grows. The influences of the roughness and the wettability on condensation are especially analyzed.
Design/methodology/approach
The non‐equilibrium molecular dynamics simulation method is used to simulate the condensation. In order to maintain the process, a simple and effective molecule insertion mechanics is proposed.
Findings
The results show that the wall‐neighboring liquid structure becomes more regular with stronger wettability. The temporal parametric profiles show that the condensation does not progress at a constant rate but exhibit obvious unsteady characteristics of gradual deceleration, especially for strong wettability cases. Analysis based on heat and mass transfer indicates that the influence of wettability is quite superior to that of the roughness. The enhancement should be explained by the more fluent and effective energy exchange between solid and liquid particles caused by strong solid‐liquid coupling other than by the ordering structure itself.
Practical implications
The paper's findings suggest that the wettability should be paid special attention when the heat transfer performance of the microscale condensation is predominantly focused on.
Originality/value
The paper provides a vapor‐liquid‐solid model with molecule insertion. This model can be used to evaluate the contact thermal resistance and the thermal boundary conditions in condensation under different geometric conditions.

Abstract
Purpose
This paper explores two museums in Taiwan, both former sites of incarceration, and asks how they reflect Taiwan’s evolving relationship with the past. Taiwan has successfully emerged from its authoritarian past into a democratic present; yet, it still bears the scars of its traumatic and violent history in the places where trauma and pain was exacted over Taiwanese people by different regimes. Two of these places are former prisons, now museums with common histories of incarceration, but very different approaches to presentation of traumatic pasts. This paper aims to understand the selective presentation of narratives of punishment in prison museums in Taiwan and what they reflect about Taiwan’s national identity.
Design/methodology/approach
This research used a qualitative ethnographic methodology, approaching prison museums as research sites with multidimensional textual, spatial and visual data. This study used a narrative ethnology approach to analyse the content, structure and social context surrounding the stories told about punishment at the sites.
Findings
While the Jingmei White Terror Memorial Park documents past abuses under the authoritarian Kuomindang Government (1945–1987), the narratives presented at the Chiayi Prison Museum, constructed under Japanese colonial rule (1895–1945), ignore past colonial violence. This study argues that the invisibility of past colonial violence in Chiayi prison museum acts to strengthen Taiwan’s multicultural national identity, while Jingmei WTMP acts to valorise political prisoners as heroic fighters for Taiwan’s democracy and human rights.
Originality/value
This research makes a contribution to the museum studies literature through extending understanding of the relationship between former carceral spaces and national identity projects.

Abstract
Purpose
Based on stimulus-organism-response model, the purpose of this paper is to develop an integrated model to explore the effects of six marketing-mix components (stimuli) on consumer loyalty (response) through consumer value (organism) in social commerce (SC).
Design/methodology/approach
In order to target online social buyers, a web-based survey was employed. Structural equation modeling with partial least squares (PLS) is used to analyze valid data from 599 consumers who have repurchase experience via Facebook.
Findings
The results from PLS analysis show that all components of SC marketing mix (SCMM) have significant effects on SC consumer value. Moreover, SC customer value positively influences SC customer loyalty (CL).
Research limitations/implications
The data for this study are collected from Facebook only and the sample size is limited; thus, replication studies are needed to improve generalizability and data representativeness of the study. Moreover, longitudinal studies are needed to verify the causality among the constructs in the proposed research model.
Practical implications
SC sellers should implement more effective SCMM strategies to foster SC CL through better SCMM decisions.
Social implications
The SCMM components represent the collective benefits of social interaction, exemplifying the importance of effective communication and interaction among SC customers.
Originality/value
This study develops a parsimonious model to explain the over-arching effects of SCMM components on CL in SC mediated by customer value. It confirms that utilitarian, hedonic, and social values can be applied to online SC and that SCMM can be leveraged to achieve these values.

Abstract
Purpose
The purpose of this study is to examine the effect of perceived value on customer loyalty through affective commitment in the online group-buying (OGB) context. This paper addressed the following questions: what are the factors affecting customer loyalty (i.e. revisit intention and buy more intention); and how do referral rewards moderate the impact of affective commitment on customer loyalty?
Design/methodology/approach
All data were collected from OGB websites’ members in Taiwan. The total number of respondents to the online survey was 403. The data were analyzed using structural equation modeling (SEM) to test a perceived value–commitment–loyalty model.
Findings
This study shows that three proposed antecedents (i.e. OGB scheme value, hedonic value and social value) can trigger customer loyalty through affective commitment. Monetary savings, a variety of merchandise and aspirational products are all critical OGB scheme value components. The results also show that referral reward importance positively moderates the relationship between affective commitment and revisit intention.
Practical implications
The findings have implications for managing people and work tasks in OGB websites. First, understanding the importance of dimensions of value should enable OGB managers to develop more accurate targeting strategies. This study provides guidance on the design of the platform and the OGB scheme, for the effective allocating of marketing resources. Second, a referral reward mechanism can be a critical CRM tool; in addition to the potential to attract new customers, they can also help to retain existing customers. This mechanism is a very effective method to enhance customer stickiness.
Originality/value
The marketing literature generally recognizes the importance of developing and maintaining long-term relationships with customers. This study is the first one to explore the importance of affective commitment in developing and sustaining loyal relationships in the OGB context. Referral rewards are an important moderator variable: affective commitment has a stronger effect on the revisit intention when the referral rewards are high. The findings of this study provide insights into how OGB website developers can create customer commitment and more effectively retain existing customers through the use of referral rewards.

Abstract
Purpose
Given the increasing intensity of highly competitive markets, this study aims to evaluate the effect of salespeople's emotional regulation, adaptive selling and customer-oriented behavior on sales performance.
Design/methodology/approach
A research model was tested by using a sample of 288 respondents from the logistics industry in Taiwan. Structural equation modeling was used to examine the relationships between emotional regulation, adaptive selling, job resourcefulness, customer-oriented behavior and sales performance.
Findings
The results indicate that emotional regulation, adaptive selling and job resourcefulness can improve customer-oriented behavior, and that customer-oriented behavior and job resourcefulness can enhance sales performance. By highlighting the role of job resourcefulness, the authors find a positive moderating effect among these four dimensions.
Originality/value
The findings can help salespeople integrate customer-oriented behaviors into strategic changes to regulate their own emotions and those of others to productively address and resolve difficult business conditions. The theoretical and managerial implications of this work's contributions to international logistics are also discussed.

Abstract
Purpose
The purpose of this paper is to investigate the post-adoption stage of Voice over Internet Protocol (VoIP) telephony diffusion, examining usage behavior based on Shih and Venkatesh’s use-diffusion (UD) model.
Design/methodology/approach
The research model incorporates technology sophistication, complementary technologies, personal innovativeness, self-efficacy, trust propensity, media exposure, subjective norms, and word-of-mouth (WOM) referrals as UD determinants; rate of use and variety of use as usage variables; intense use, specialized use, nonspecialized use, and limited use as UD patterns; and satisfaction and intention to use future-related technologies as UD outcomes. Data used to test the research model were collected using a web-based online questionnaire form; 360 valid responses were obtained. Partial least squares, multinomial logistic regression, and analysis of variance were used to analyze data.
Findings
The results reveal that variety of use, self-efficacy, propensity to trust, media exposure, subjective norms, and WOM referrals increase rate of use, while complementary technologies, personal innovativeness, self-efficacy, media exposure, and subjective norms widen variety of use; variety of use is essential in predicting UD outcomes; when choosing limited use as the reference category, more than half of the UD determinants are capable of predicting UD patterns; and generally, intense users are more satisfied with VoIP telephony, while limited users have less intention to use future-related technologies.
Originality/value
The present study focuses on the post-adoption stage, thereby extending the frontiers of research on the diffusion of VoIP telephony. Academics can obtain some evidence of the explanatory power of the UD model in the context of VoIP telephony use, and practitioners can obtain fresh insights into the dynamics of VoIP telephony usage behavior.

Abstract
Purpose
Creative performance relies on the capability of developing and presenting an original concept or idea, and the collaborative production of creative content which enhances feeling of connection with others and formation of strong community. The purpose of this paper is to apply the theory of work performance containing four dimensions (capacity, opportunities, willingness, and performance) to investigate how the capabilities of social network sites enhance user creative performance through collective social capital and information capital (opportunities) for and individual habit of use (willingness) of the user to engage in social learning process.
Design/methodology/approach
Many measurement items are adapted from the literature, except those measuring the constructs of social media capabilities (i.e. transmission velocity (TV), parallelism, symbol sets, rehearsability, and reprocessability) and user creative performance. The study uses survey method to collect data from social media network (SMN) users in Taiwan. Facebook is chosen as the source because it is the most prevalent and sophisticated social media platform that provides a home for users to interact and communicate. Structural equation modeling with partial least square is used to analyze the usable data collected from 533 Facebook users.
Findings
The results show that the constructs are significantly and positively correlated, meaning that social media capabilities enable social capital, information capital, and habit of use to improve user creative performance in SMNs. Three out of five social media capabilities (i.e. TV, parallelism, and rehearsability) are identified as the key enablers.
Research limitations/implications
Because of the sampled surveyed subjects and the single research method, there are some limitations in this study. The research results may lack generalizability that should be taken into account when they are interpreted. The authors encourage researchers to test the proposed theoretical model further with additional subjects, variables, and linkages.
Practical implications
The findings of this research shed light for managers of SMN platforms on how to manage the platforms more effectively. A healthy SMN platform must implement at least these three media capabilities: the functions of news feed (i.e. TV), chat (i.e. parallelism), edit (i.e. rehearsability), in order to sustain its service.
Social implications
This study confirmed that user creative performance can be increased in various ways through social capital, information capital, and habit of use. Company management should use SMNs (e.g. Facebook or Twitter) to enable employees to interact and exchange ideas and promote “coopetition” among employees across the company. If the organizational culture supports free expression of ideas and sharing of opinions, the development and robustness of group creativity can be enhanced, leading to higher competitive advantage for a company against its competitors.
Originality/value
Past studies related to individual creativity have mostly discussed it as a personality trait or talent; yet, personality trait or talent is implicit until it is shown by one’s behavior. Thus, for the collective performance of user creativity on SMNs, the authors elicit individual creativity through the creative performance manifested by user behavior. Furthermore, the authors confirm that social capital, information capital, and habit of use are the critical antecedents of user creative performance, and that the five social media capabilities are the enablers of social capital, information capital, and habit of use on SMNs.

Abstract
Purpose
The purpose of this paper is to use comprehensive model to investigate the effects of particle physical properties on in-flight nano-particles behavior for the radio frequency suspension plasma spray.
Design/methodology/approach
In this paper, both the effects thermal properties of solvent and solid particle on the evolution of particle size, velocity and temperature are discussed. Besides, the numerical analysis is also conducted to investigate the influences of particle physical properties on the characteristic distributions of particles for poly-disperse cases.
Findings
Results show the thermal properties of solvent have critical effects on the discharged point of the solid particles, but little influence on the final particle velocity and size, as well as their distributions. The final state of particle temperature is mainly determined by the solid particle thermal properties, especially depending on the boiling point.
Originality/value
Most of the former studies took the experimental approaches and mainly focussed on the operating conditions effects. While beyond the operating conditions, the variety of particle physical and thermal properties also has strong effect on particle heating performance.
