Abstract
An eigenvalue method is presented for solving the transient heat conduction problem with time‐dependent or time‐independent boundary conditions. The spatial domain is divided into finite elements and at each finite element node, a closed‐form expression for the temperature as a function of time can be obtained. Three test problems which have exact solutions were solved in order to examine the merits of the eigenvalue method. It was found that this method yields accurate results even with a coarse mesh. It provides exact solution in the time domain and therefore has none of the time‐step restrictions of the conventional numerical techniques. The temperature field at any given time can be obtained directly from the initial condition and no time‐marching is necessary. For problems where the steady‐state solution is known, only a few dominant eigenvalues and their corresponding eigenvectors need to be computed. These features lead to great savings in computation time, especially for problems with long time duration. Furthermore, the availability of the closed form expressions for the temperature field makes the present method very attractive for coupled problems such as solid—fluid and thermal—structure interactions.

Abstract
The primary purpose of this article is to investigate empirically for the US the potential impact of monetary and fiscal policy upon real economic activity using the “St. Louis equation” approach. Only lagged values of the policy variables are included in the estimation to ensure their statistical exogeneity. Hsiao's (1981) multivariate technique is employed to determine the model lag specification. The empirical results suggest that only fiscal policy as measured by high‐employment tax changes can exert a significant lasting impact upon real GNP. Monetary policy, on the other hand, has only a temporary effect on real GNP. The results also show that both monetary and fiscal policy have significant and permanent effects on nominal GNP, the former via its permanent effect on prices and the latter through its permanent effect on real GNP.

Abstract
The luxury brands sales in emerging markets will see rapid growth. When entering the emerging markets, luxury fashion brands always find it challenging to balance adaption with local consumer culture and standardization to maintain their global brand image. The present study attempts to examine this intriguing issue of adaptation and standardization and many other challenges for luxury brands in the emerging market by focusing on China’s luxury market. A case study on China is conducted, which consisted of reviewing academic literature and consulting trade reports, examining over 50 luxury brands’ Chinese websites, reading newspaper articles, conducting field trips to luxury retail outlets, and studying luxury brands’ advertisements in major Chinese fashion magazines. We identified five intriguing market characteristics that must be taken into account in order to succeed in this market. Specifically, we found that to perform well in China’s luxury market, luxury brands should have a good understanding of the conflicting Chinese social cultural sentiments toward luxury consumption. Luxury brands should seek a balance between standardization and adaptation and appeal to both consumers’ converging needs and their desire for products that embrace local elements. Further, given the unique consumer characteristics, luxury brands should better serve the young and economically diverse consumer base in China.

Abstract
Purpose
Actual product-harm crises pose significant challenges to firms, but so can defaming product-harm crises, which are defined as crises caused by false or malicious rumors made by consumers or competing firms. Unlike typical product-harm crises, in defaming product-harm crises, the truth often emerges only after substantial damage has been done to the victim firm. Thus, crisis management strategies in these two cases may be different. The paper aims to discuss these issues.
Design/methodology/approach
Using a defaming product-harm crisis that involved two competing firms, this paper examines how the firms changed their advertising strategies and how the changes affected consumers’ online search behavior regarding the two firms.
Findings
The analyses show that after the crisis, the offending firm sensitively reacted to its own and the victim firm’s advertising levels, but the victim firm did not react to the offending firm’s advertising as it had previously. The effectiveness of advertising on consumers’ online search weakened for both firms after the crisis.
Originality/value
The paper provides a new insight about marketing strategies and their effectiveness in the product-harm crisis literature.

Abstract
Although the term “trigger event” is commonly accepted and frequently mentioned by many disciplines in conjunction with sensemaking, research attention on the trigger event construct is sorely lacking. We chose to examine this construct within a specific setting that global leaders have to master – the intercultural context. After reviewing the relevant literature, we created an original model of trigger events and sensemaking in the intercultural context, which is accompanied by propositions that determine the likelihood of an event rising to the level of a trigger. It is our hope that this theoretical model will lead to a better understanding of how trigger events function in general. The chapter contributes to a greater understanding of the cognitive element of global leadership effectiveness. Finally, the model has practical implications for intercultural and global leadership training and executive coaching.

Abstract
“Velocity of money is a ‘purely statistical concept’ of no causal significance, which varies automatically with changes in the quantity of money in relation to total expenditure,” as concluded in the late 1950s by the well‐known Radcliffe Committee in Great Britain (Kaldor, p. 19). This view, although it has been supported from time to time by prominent economists such as Kaldor and Kahn, is not generally accepted. Velocity and its ‘stability,’ which is closely related to the stability of the demand for money, are considered by many economists to be very important in economic affairs and to constitute an important foundation of the monetarist doctrine.

Abstract
Purpose
The purposes of this study are to identify the ways that luxury fashion brands can leverage in metaverse retailing, and give insights to practitioners in the fashion industry who are planning to launch metaverse retailing.
Design/methodology/approach
To offer a balanced view of available evidence, this study adopted a literature review approach and attempted to collect all existing academic journal articles on the issues related to metaverse retailing and luxury fashion brands. A comprehensive literature search was conducted in electronic databases Google Scholar, Web of Science, Scopus, Pro Quest and Science Direct from January 2023 to April 2024. Based on the results of the research in literature, real-life examples of luxury fashion brands were used to explain the ways that luxury fashion brands in the metaverse retailing can be put into practice.
Findings
The findings have revealed that there are many ways that luxury fashion brands can leverage in the metaverse retailing. The fusion of metaverse-related technologies provides brands with a wide platform of choices that can create immersive, personalized marketing experiences for customers. Four roles of metaverse are identified: (1) enhance of immersive experience; (2) provide big data interface to smart decision-making; (3) form high-fidelity simulated space; and (4) maintenance economic system and making of identification. To further enhance the four roles of metaverse, four types of technologies and 15 components for metaverse can be adopted by luxury fashion brands.
Research limitations/implications
While this paper provides a literature review and real-life examples of luxury fashion brands in the metaverse retailing to explain the findings, further research is needed to evaluate the effectiveness of current efforts in the development of luxury fashion brands in the metaverse retailing through collecting both quantitative and qualitative data. Also, future studies may attempt to explore the challenges of investigating consumers in response to luxury fashion brands in the metaverse retailing.
Practical implications
The metaverse is turning imagination into reality through the integration of multiple technologies and is gaining momentum in tech. With technology leading the way, business leaders and brands must not only rethink retail but also bring immersive shopping experiences into the future. Metaverse has immense potential to transform the retail industry, thus the leading global and local firms must embrace innovation and new technologies, and prioritize “metaverse transformation” for their business. Based on the results of this study, some emerging practices pertaining to metaverse retailing are provided.
Originality/value
To the best of the authors’ knowledge, it would seem that this is the first work that conducts a literature review of the relevant academic journal articles addressed to the practitioners or managerial audiences in the area of luxury fashion industry who are concerned about the development of metaverse retailing. This paper identifies the ways that luxury fashion brands can leverage in the metaverse retailing and gives insights to practitioners in the luxury fashion industry who are planning to launch metaverse retailing.

Abstract
Survey of period infinite element developments The first infinite elements for periodic wave problems, as stated in Part 1, were developed by Bettess and Zienkiewicz, the earliest publication being in 1975. These applications were of ‘decay function’ type elements and were used in surface waves on water problems. This was soon followed by an application by Saini et al., to dam‐reservoir interaction, where the waves are pressure waves in the water in the reservoir. In this case both the solid displacements and the fluid pressures are complex valued. In 1980 to 1983 Medina and co‐workers and Chow and Smith successfully used quite different methods to develop infinite elements for elastic waves. Zienkiewicz et al. published the details of the first mapped wave infinite element formulation, which they went on to program, and to use to generate results for surface wave problems. In 1982 Aggarwal et al. used infinite elements in fluid‐structure interaction problems, in this case plates vibrating in an unbounded fluid. In 1983 Corzani used infinite elements for electric wave problems. This period also saw the first infinite element applications in acoustics, by Astley and Eversman, and their development of the ‘wave envelope’ concept. Kagawa applied periodic infinite wave elements to Helmholtz equation in electromagnetic applications. Pos used infinite elements to model wave diffraction by breakwaters and gave comparisons with laboratory photogrammetric measurements of waves. Good agreement was obtained. Huang also used infinite elements for surface wave diffraction problems. Davies and Rahman used infinite elements to model wave guide behaviour. Moriya developed a new type of infinite element for Helmholtz problem. In 1986 Yamabuchi et al. developed another infinite element for unbounded Helmholtz problems. Rajapalakse et al. produced an infinite element for elastodynamics, in which some of the integrations are carried out analytically, and which is said to model correctly both body and Rayleigh waves. Imai et al. gave further applications of infinite elements to wave diffraction, fluid‐structure interaction and wave force calculations for breakwaters, offshore platforms and a floating rectangular caisson. Pantic et al. used infinite elements in wave guide computations. In 1986 Cao et al. applied infinite elements to dynamic interaction of soil and pile. The infinite element is said to be ‘semi‐analytical’. Goransson and Davidsson used a mapped wave infinite element in some three dimensional acoustic problems, in 1987. They incorporated the infinite elements into the ASKA code. A novel application of wave infinite elements to photolithography simulation for semiconductor device fabrication was given by Matsuzawa et al. They obtained ‘reasonably good’ agreement with observed photoresist profiles. Häggblad and Nordgren used infinite elements in a dynamic analysis of non‐linear soil‐structure interaction, with plastic soil elements. In 1989 Lau and Ji published a new type of 3‐D infinite element for wave diffraction problems. They gave good results for problems of waves diffracted by a cylinder and various three dimensional structures.
