In order to improve the robustness of bare-steel and composite structures in fire, a novel axially and rotationally ductile connection has been proposed in this paper.

The component-based models of the bare-steel ductile connection and composite ductile connection have been proposed and incorporated into the software Vulcan to facilitate global frame analysis for performance-based structural fire engineering design. These component-based models are validated against detailed Abaqus FE models and experiments. A series of 2-D bare-steel frame models and 3-D composite frame models with ductile connections, idealised rigid and pinned connections, have been created using Vulcan to compare the fire performance of ductile connection with other connection types in bare-steel and composite structures.

The comparison results show that the proposed ductile connection can provide excellent ductility to accommodate the axial deformation of connected beam under fire conditions, thus reducing the axial forces generated in the connection and potentially preventing the premature brittle failure of the connection.

Compared with conventional connection types, the proposed ductile connection exhibits considerable deformability, and can potentially enhance the robustness of structures in fire.

The purpose of this paper is to examine how customer orientation affects frontline service workers’ deep acting and to what extent the effect is moderated by the severity of dysfunctional customer behavior (DCB). Service organizations usually want their employees to demonstrate sincere emotions during customer encounters.

The study employed a mixed method design using measured variables (e.g. customer orientation) and a scenario-based manipulated variable (i.e. DCB severity). Data from 237 service workers were used to investigate the theoretical model.

Results showed that perspective taking and emotional sensitivity mediate the positive effect of customer orientation on deep acting. Furthermore, the influence of emotional sensitivity on deep acting is positive when DCB is less severe, but becomes non-significant when DCB becomes severe.

Because the DCB severity is manipulated as a single event, future research can examine its influence based on employees’ experiences. Also, future studies may investigate other mechanisms to explain customer orientation’s effects on deep acting.

This paper provides service organizations an understanding of the key roles of emotional sensitivity and perspective taking in driving deep acting as well as the importance of monitoring DCB severity.

The study is one of the first in marketing to examine the different influences of DCB severity on important employee outcomes. This study also identifies two important mediators to explain how customer orientation drives deep acting.

The purpose of this study is two-fold: (1) identify shifts in prioritization of corporate social responsibility (CSR) issues and (2) identify the CSR issues in which companies are currently involved, as indicated in their website communications. Corporate communications are also examined for possible variations of CSR focus between manufacturers, retailers and service firms.

In order to identify the CSR issues in which companies are currently involved and detect any shifts, a content analysis was conducted of the 2021 Fortune 100 company websites, specifically cataloging CSR communications. This data was compared with CSR communications on Fortune 100 company websites in 2015. CSR issues are also examined within each industry categorization: manufacturing, retail and service.

Findings indicate that companies have reduced the number of CSR issues prioritized in their website communications. In 2015, companies gave prominence to an average of seven CSR issues on their websites, today the average is three CSR issues. Today, the CSR issues prioritized most commonly are diversity and sustainability. However, these issues are prioritized by only half of the companies. Previously, the vast majority of Fortune 100 companies prioritized the same top issues. That is not the case today. This shift may suggest that companies are narrowing their focus to fewer CSR issues, perhaps those that align with company goals.

This study provides information to keep company executives and academicians abreast of prominent CSR issues and terminology found in the marketplace. As executives make choices about committing resources to social issues, knowledge of what the Fortune 100 is doing can help in that decision-making process.

This study aims to determine the extent to which the use of coordinating conjunctions enhances or impairs definitional clarity.

In two studies, a sample of 736 construct definitions from the Journal of Marketing, Journal of Marketing Research and Journal of Consumer Research over a 30-year period was judged for ambiguity and vagueness by both academic and lay judges.

The authors demonstrate that constructing definitions using both “and” and “or” increases the ambiguity and vagueness of the construct’s meaning. The most frequently used conjunction is “and” which appeared in 42 per cent of the definitions. A significant percentage (26 per cent) contain the conjunction “or.”

A framework for understanding alternative interpretations of “and” or “or” is developed. Five recommendations are proposed for evaluating the use of “and” and “or” in construct definitions. Theorists in all academic fields should not use both “and” and “or” in the same construct definition.

A five-step process is proposed for evaluating the use of “and” and “or” in construct definitions. Theorists should not use both “and” and “or” in the same construct definition.

This is the first exploration of how specific wording patterns used in construct definitions in academic research affect the clarity of the definition.

Under the background of the overall increase of China's economic policy uncertainty and the urgent need for the transformation and upgrading of the substantial economy, this paper studies the time-varying causality between China's economic policy uncertainty and the growth of the substantial economy through bootstrap rolling window causality test, further refines economic policies and studies the causal differences between different types of economic policies and substantial economic growth, refining the conclusions of previous studies.

This paper first studies the causal relationship between China's economic policy uncertainty and substantial economic growth in the full sample period through bootstrap Granger causality test. Then, the paper tests the short-term and long-term stability of the parameters of the VAR model, and it is found that the model parameters are unstable in both the short and long term, so the results of the Granger causality test of the full sample are not credible. Finally, we conduct a dynamic test of the causal relationship between China's economic policy uncertainty and substantial economic growth by means of rolling window, so as to comprehensively analyze the dynamic characteristics and sudden changes of the relationship between them.

The research shows that economic policy uncertainty in China has a significant inhibiting effect on the growth of substantial economy. Growth in the substantial economy will drive up economic policy uncertainty before 2016 and restrain it after that. In addition, this paper further subdivides economic policy uncertainty to explore the causal differences between different types of economic policy uncertainty and substantial economic growth. The test results show that the relationship between them has obvious policy heterogeneity. The fiscal policy uncertainty and the monetary policy uncertainty, as the main policy means in China, has a significant impact on the growth rate of substantial economy in multiple ranges, but the effect time is short. Although trade policy uncertainty has a significant impact on the growth rate of substantial economy only during the financial crisis, the effect lasts for a long time. The impact of exchange rate and capital account policy uncertainty on the growth rate of substantial economy is mainly reflected after 2020.

The values of this paper are as follows: First, the economic policy uncertainty is combined with the growth of substantial economy, which makes up the gap of previous studies. Second, the economic policy uncertainty is further subdivided. The paper explores the causal differences between different types of economic policy uncertainties and the growth of substantial economy, so as to make the research more detailed. Finally, different from the previous static analysis, this paper uses dynamic model to examine the relationship between China's economic policy uncertainty and the growth of substantial economy from a dynamic perspective, with richer research conclusions.

The purpose of this paper is to investigate how and when used by employees influences witnessing customers’ willingness to spread positive word of mouth (WOM).

This research used a qualitative method to develop a typology of necessary evil using two pilot studies and an experimental study to test the theoretical model.

The results show that the necessary evil used by employees to manage dysfunctional customers positively influences witnessing customers’ perceptions of distributive, procedural and interactional justice and their subsequent deontic justice perceptions, resulting in their willingness to spread positive WOM. Moreover, the positive influence of necessary evil on witnessing customers’ responses is strengthened when dysfunctional customer behavior (DCB) targets another customer as opposed to an employee.

This research offers service providers a better understanding of how to manage DCBs.

This paper contributes to the existing literature by introducing necessary evil to the service literature, proposing a new typology of employee response strategies to DCB based on necessary evil and examining how necessary evil drives positive customer responses. Additionally, it is among the first to examine the relationship between deontic justice and traditional justice mechanisms.

The purpose of this paper is to investigate the state of logistics management research in Asia. The study focuses on the research agenda, the topics of interest, and the extent of research collaboration in logistics theory building and knowledge specific to Asia.

This study uses a mixed methods approach namely, content analysis drawn from the articles found in six well-recognized peer-reviewed logistics management related journals from 2003 to 2013, followed by social network analysis which is applied on the selected articles to provide a structure of the collaboration relationship.

Initial findings suggest that there are some scholars in Asia who are instrumental in research collaboration and in building a body of knowledge on logistics management focused on Asia. More co-production of knowledge from deeper and tightly knit industry-academic collaboration is needed to progress this domain. Most of the published work use an empirical instrument drawn from the resource-based view to explore firm level supply chain collaboration and strategy. This suggests a positivist research tradition within logistics. There is a shortage of studies conducted on the supply chain as a network of enterprises.

The review of the articles is limited to six logistics specific journals and the authors only concentrate on logistics management research focused on Asia. The contributions from the other journals may have been missed. More collaboration at the institutional, national, and international levels is called for especially on cross-collaboration between practice and theory.

Though the analysis is restricted to 260 articles found in six journals, this paper can shed light on the research needs from different perspectives and facilitate the progress of logistics management research in Asia.

This is the first paper to discuss the state of logistics management research collaboration in Asia, and provides an overview of the research issues, topics, and approaches undertaken thus far. Through this work, this study hopes that it will encourage greater research collaboration between industry and academia, and academics themselves.

In recent years, China's marine industry has maintained rapid growth in general, and marine-related economic activities have continued to improve. The purpose of this research is to analyze the basic situation of China's marine economy development, identify the problems therein, forecast development trends and propose policy recommendations accordingly.

This research conducts a comprehensive and detailed analysis of the development of China's marine economy with rich data in diversified aspects. The current situation of China's marine economy development is analyzed from the perspective of scale and structure, and the external and internal development environment of China's marine economy is discussed. With the application of measurement and prediction method such as trend extrapolation, exponential smoothing, grey forecasting and neural network method, the future situation of China's marine economy development is forecasted.

In a complex environment where uncertainties at home and abroad have increased significantly, China's marine economy development suffers tremendous downward pressure in recent years. As China has achieved major achievements in the prevention and control of the COVID-19 epidemic, the marine economy development will gradually return to normal. It is estimated that the gross marine production value in 2022 will exceed 10 trillion yuan. China's marine economy will continue to maintain a steady growth trend in the future, and its development prospects will remain promising.

This research explores the current situation and trends of China's marine economy development and puts forward policy recommendations to promote the steady and health development of China's marine economy accordingly.

Fire hazards and full-scale structural tests have provided evidence that the beam-column connections of building frames are the weakest structural elements, which are vulnerable to fracture in fire. Connection fractures may lead to extensive damage or even progressive collapse. However, current design methods for connections are solely based on ambient-temperature behaviour, the additional forces and rotations generated in fire are not taken into account. The Structural Fire Engineering Research Group of the University of Sheffield is involved in a European-collaborative project which concerns the behaviour and robustness in fire of practical connections to composite columns. This includes two natural fire tests in a full-scale composite structure in Veselí, the Czech Republic. The Sheffield team was responsible for predicting the structural behaviour in the tests before they were conducted. This assessment was conducted using the specialist structural fire engineering FEA program Vulcan. This paper reports the results of this predictive analysis.

Lattice Boltzmann method (LBM) is employed to explore friction factor of single-phase fluid flow through porous media and the effects of local porous structure including geometry of grains in porous media and specific surface of porous media on two-phase flow dynamic behavior, phase distribution and relative permeability. The paper aims to discuss this issue.

The 3D single-phase LBM model and the 2D multi-component multi-phase Shan-Chen LBM model (S-C model) are developed for fluid flow through porous media. For the solid site, the bounce back scheme is used with non-slip boundary condition.

The predicted friction factor for single-phase fluid flow agrees well with experimental data and the well-known correlation. Compared with porous media with square grains, the two-phase fluids in porous media with circle grains are more connected and continuous, and consequently the relative permeability is higher. As for the factor of specific porous media surface, the relative permeability of wetting fluids varies a little in two systems with different specific surface areas. In addition, the relative permeability of non-wetting fluid decreases with the increasing of specific surface of porous media due to the large flow resistance.

Fluid-fluid interaction and fluid-solid interaction in the SC LBM model are presented, and schemes to obtain immiscible two-phase flow and different contact angles are discussed. Two-off mechanisms acting on the wetting fluids is proposed to illustrate the relative permeability of wetting fluids varies a little in two systems with different specific surface.
