Abstract
Purpose
Emerging real‐time multimedia services over IP have penetrated into the daily lives of normal people with the advent of advanced broadband communications and innovated interconnection technologies. To protect shared Internet from unfairness and further congestion collapse, rate control plays a crucial role for many multimedia services such as streaming applications. Streaming applications such as video on demand (VoD) or voice over IP (VoIP) services face some critical problems such as insufficient bandwidth and improper performance of transmission protocols. Besides, the new generation networks are anticipated to integrate all heterogeneous wired and wireless networks and offer seamless customized multimedia services anywhere, anytime. However, wireless networks usually with low and variable bandwidth, and non‐congestion related loss do bring the challenge to the existing transport protocol, such as TCP, TFRC etc.
Design/methodology/approach
The paper uses simulations and compares other methods. The purpose of this paper is to address these issues. The paper, proposes a rate control scheme named Jitter‐based Rate Control (JRC) to fit wired‐wireless hybrid network which has better performance than the current rate control scheme.
Findings
Extensive simulations and comparisons with other methods verify the effectiveness of our method for accurate and smooth estimation, no matter whether the wireless links are located.
Originality/value
The paper introduces the JRC.

Abstract
The e-freight program launched by the International Air Transport Association (IATA) has gradually become a standard specification for international air freight operations. This study examined critical factors affecting air freight forwarders’ decision to adopt the IATA e-freight using a technology-organization-environment model with air freight forwarders in Taiwan as the base. Our findings show that ‘information technology (IT) competence’, ‘trading partner pressure’, ‘government policy’ and ‘competitive pressure’ all have significant positive effects on air freight forwarders’ decision to adopt the e-freight and the top three factors among these are ‘government funding’, ‘government’s active promotion’ and ‘government’s requirement of electronic air waybill (e-AWB)’. Finally, this study proposes strategies that can encourage air freight forwarders to decide on e-freight adoption for the information of relevant oK regyawniozradtison International Air Transport Association (IATA); IATA e-freight; Technology organization environment model; Air freight forwarder

Abstract
Purpose
The Western-centric nature of research into corporate social responsibility (CSR) has left gaps in one’s understanding of local culture's role in augmenting or undermining the impact of firms' CSR policies. This paper constructs and tests variables measuring “Confucian values” mediation between Chinese employees' perceived CSR and their job satisfaction, organizational commitment and organizational citizenship behavior.
Design/methodology/approach
The hypotheses were tested through structural equation modeling, using data from 311 responses completed by employees at Chinese private companies, located in China's Cheng-Yu economic area (Chongqing and Chengdu).
Findings
Chinese employees' perceived CSR had a positive significant effect on job attitudes (job satisfaction and organizational commitment). However, perceived CSR had no significant positive impact on organizational citizenship behavior. The authors also found that Confucian values are a partial mediator between perceived CSR and job attitudes and a full mediator between perceived CSR and organizational citizenship behavior.
Originality/value
The results enrich one’s understanding of cultural values in these relationships and suggest further research into how firms and governments in Confucian-based societies can better operationalize Confucian values to argument the firm's and country's CSR identity, thus improving job attitudes and public relations among customers who share this cultural heritage. For non-Confucian societies and foreign firms operating in China, the results encourage searches for Confucian value substitutes, such as trust and education, to incorporate into CSR mechanisms that promote these values among employees. The authors suggest approaches for furthering these agendas.

Abstract
Purpose
The purpose of this paper is to briefly summarize and review the theories and methods of complex structures’ dynamic reliability. Complex structures are usually assembled from multiple components and subjected to time-varying loads of aerodynamic, structural, thermal and other physical fields; its reliability analysis is of great significance to ensure the safe operation of large-scale equipment such as aviation and machinery.
Design/methodology/approach
In this paper for the single-objective dynamic reliability analysis of complex structures, the calculation can be categorized into Monte Carlo (MC), outcrossing rate, envelope functions and extreme value methods. The series-parallel and expansion methods, multi-extremum surrogate models and decomposed-coordinated surrogate models are summarized for the multiobjective dynamic reliability analysis of complex structures.
Findings
The numerical complex compound function and turbine blisk are used as examples to illustrate the performance of single-objective and multiobjective dynamic reliability analysis methods. Then the future development direction of dynamic reliability analysis of complex structures is prospected.
Originality/value
The paper provides a useful reference for further theoretical research and engineering application.

Abstract
Purpose
Studies have explored the determinants of customer advocacy because of customer advocacy's vital role in improving the efficiency and effectiveness of marketing. The current research complements the existing literature in the hospitality field by examining the association between restaurant innovativeness and customer advocacy while also investigating the mediating roles of self-image congruity and customer engagement.
Design/methodology/approach
The statistical software AMOS version 25 and bootstrapping were employed to test the hypotheses. Purposive sampling was employed for participant recruitment, and a self-administered questionnaire was used to collect data. Data were collected from Taiwanese customers who had dined at selected restaurants.
Findings
The results from 385 restaurant customers reported that self-image congruity had an indirect impact on customer advocacy through customer engagement. Customer advocacy was influenced by restaurant innovativeness through the mediation of customer engagement. The influence of restaurant innovativeness on customer advocacy was positively and sequentially mediated by self-image congruity and customer engagement.
Practical implications
Restaurant innovativeness is linked to customer advocacy through self-image congruity and customer engagement. Thus, restaurant managers should implement strategies focusing on innovativeness to improve self-image congruity and engagement among customers.
Originality/value
The current research may be the first to provide a research model that explores restaurant innovativeness, self-image congruity, customer engagement and customer advocacy in the hospitality context. This study also has practical implications for enhancing customer advocacy.

Abstract
Purpose
Prosocial service behaviors play a major role in the hospitality industry. However, few studies have examined how job resourcefulness affects prosocial service behaviors. This paper aims to investigate the relationship between job resourcefulness and prosocial service behaviors as well as clarify the mediating effect of work engagement.
Design/methodology/approach
A questionnaire was developed to collect data from 282 frontline service employees in Taiwan’s hotel industry. Structural equation modeling was conducted to test the hypotheses of this research.
Findings
The results indicate that job resourcefulness is positively related to role-prescribed service behaviors, extra-role service behaviors and cooperation. Furthermore, work engagement mediates the relationship between job resourcefulness and prosocial service behaviors.
Research limitations/implications
The design of cross-sectional research restricts inference to the findings of cause–effect relationships. Also, the design of this study could not rule out the effect of common method variance, as all the data used in the study were acquired using the same questionnaire.
Originality/value
The current study contributes to the hospitality management research by investigating the link between job resourcefulness and prosocial service behaviors, and elaborating the partially mediating role of work engagement in this relationship.

Abstract
Purpose
Researchers and practitioners have remarked the critical nature of job crafting for employee and organizational effectiveness in the hotel industry. However, few studies have investigated the determinants of job crafting, especially the role of personality traits. Hence, this study aims to address this research gap by exploring how job resourcefulness influences job crafting and by clarifying the mediating role of work engagement.
Design/methodology/approach
The sample of the present study comprised 433 Taiwanese frontline hotel employees. The hypothesized relationships were tested using structural equation modeling.
Findings
The results reveal that job-resourceful employees tend to engage themselves at work. Engaged employees tend to craft their jobs individually and collaboratively. That is, work engagement is a mediator between job resourcefulness and job crafting. Finally, the job resourcefulness–work engagement–individual crafting relationship is closer than the job resourcefulness–work engagement–collaborative crafting relationship.
Research limitations/implications
The findings suggest that job resourcefulness can be considered as a criterion in selecting and retaining employees. Work engagement may serve as a mechanism for interpreting the relationship between job resourcefulness and job crafting. This study provides crucial insights to help hotel managers seek and aid employees who can actively reshape their work conditions. However, the sample comprises only frontline hotel employees and the generalization can be considered in the future studies.
Originality/value
This research is the first to examine the psychological process that mediates the connection between job resourcefulness and job crafting. The findings of this study contribute to the theory of the relationship between personality traits and job crafting and may serve as a reference in related practices.

This work seeks to analyze the heat transfer phenomena of anisotropic thermal conductivity fabrics containing electric conductive yarns.
Abstract
Purpose
This work seeks to analyze the heat transfer phenomena of anisotropic thermal conductivity fabrics containing electric conductive yarns.
Design/methodology/approach
A numerical program, based on a spectral element method, is used to assess the heating fabric with a temperature control model. The study determines suitable parameters for the fabric by evaluating the temperature uniformity on the fabric surface. Effective thermal conductivities of the fabric are obtained by comparing the experimental and numerical results with each other, using a nonlinear least‐square fitting method.
Findings
The results indicate that employing high effective thermal conductivity of non‐electric conductive yarns in a direction perpendicular to electric conductive yarns helps to increase temperature uniformity. However, the effect of the high effective thermal conductivity of electric conductive yarns is not evident. Adopting a short distance between the electric conductive yarns and a thick fabric is also beneficial in increasing temperature uniformity. If the heating fabric is applied in a place where there is easy energy transfer between the surface of the fabric and moving air, collocation with high heating power is needed to maintain the temperature. Choosing an appropriate heating source is essential when considering temperature uniformity and energy savings using a temperature controller.
Originality/value
The findings will be useful in the design of heating fabrics.
