This method will become a new development trend in subgrade structure design for high speed railways.

This paper summarizes the structural types and design methods of subgrade bed for high speed railways in China, Japan, France, Germany, the United States and other countries based on the study and analysis of existing literature and combined with the research results and practices of high speed railway subgrade engineering at home and abroad.

It is found that in foreign countries, the layered reinforced structure is generally adopted for the subgrade bed of high speed railways, and the unified double-layer or multi-layer structure is adopted for the surface layer of subgrade bed, while the simple structure is adopted in China; in foreign countries, different inspection parameters are adopted to evaluate the compaction state of fillers according to their respective understanding and practice, while in China, compaction coefficient, subsoil coefficient and dynamic deformation modulus are adopted for such evaluation; in foreign countries, the subgrade top deformation control method, the subgrade bottom deformation control method, the subsurface fill strength control method are mainly adopted in subgrade bed structure design of high speed railways, while in China, dynamic deformation control of subgrade surface and dynamic strain control of subgrade bed bottom layer is adopted in the design. However, the cumulative deformation of subgrade caused by train cyclic vibration load is not considered in the existing design methods.

This paper introduces a new subgrade structure design method based on whole-process dynamics analysis that meets subgrade functional requirements and is established on the basis of the existing research at home and abroad on prediction methods for cumulative deformation of subgrade soil.

The study endeavours to bring out a critical synthesis of the effect of quality of financial reporting in the BRICS (Brazil, Russia, India, China, and South Africa) countries pertaining to the International Financial Reporting Standards (IFRS) adoption. BRICS is the group composed by the five major emerging countries, which together represent about 42% of the population, 23% of gross domestic product (GDP), 30% of the territory, and 18% of the global trade. The study synthesised 57 quantitative, qualitative, and theoretical studies between the period 2005 and 2020. The findings reflect that the BRICS countries are far way behind with the qualitative and quantitative outcomes on IFRS adoption, which may be on a voluntary basis or mandatory basis. However, there are mixed revelation based on the implications of the domestic convergence of standards with IFRS, which demonstrate that 15 papers’ results revealed a negative impact.

This study aims to investigate the adoption and performance of Facebook fan pages (FFPs) among global airline companies in developed, least developed and developing countries.

Diffusion of innovations theory has been applied as the underlying theory in this study. By using content analysis, data were collected from the official FFPs of global airlines.

Results show no significant difference in FFP adoption among global airline companies in developed, least developed and developing countries. However, there is a significant difference in performance and timing of adoption of FFP between the countries. Airlines from developed countries adopted FFP three years earlier than developing countries and performed better than airlines from developing and least developed countries.

Because FFP is studied with limited variables, future studies can expand to other social networking sites and explore more variables to get reliable results.

Academically, this study adds to internet and technology implementation literature. Finding of poor performance on FFP implementation among airlines in developing and least developed countries could draw attention to increased engagement with fans and improve FFP performance in the future. To successfully use Facebook, airline companies should establish a two-way communication and respond to their fans.

This paper fulfils an identified need to study the difference in using FFPs among global airline companies in developed, least developed and developing countries.

Although leader humility is generally considered a positive leadership behavior, this study aims to examine when the positive influences of leader humility are likely weakened.

Data were collected from a two-wave survey. Ordinary least squares regression analyses were conducted to test the hypotheses.

Although leader humility is positively related to perceived leader support, this relationship is weakened when the environment is uncertain, resulting in comparatively lower follower performance.

Leaders should be aware that environmental constraints may weaken the desired outcomes of humility and therefore adapt leadership to situational needs.

Contrasting to predominant research on leader humility, this study examines a critical boundary condition by which its positive influences are compromised. In light of the disruption caused by the ongoing COVID-19, this study suggests that what usually are considered positive characteristics of leader humility are likely perceived as little leader support when the environment is uncertain. Findings of this study echo contingency leadership theories, which suggest that effective leadership should be context-dependent.

The purpose of this paper is to investigate the negative consequences of employee perceptions of supervisor self-interested behavior (SIB). Using social exchange theory, the authors argue that perceived supervisor SIB reduces affective commitment to the supervisor (ACS), which in turn fosters employees’ negative reciprocal behavior in the form of counterproductive work behavior – interpersonal (CWBI) and counterproductive work behavior – organizational (CWBO). In addition, the authors identify employee power distance orientation (PDO) as an important contingent factor that influences the indirect effects.

Using a final sample of 441 employees from 146 workgroups across 6 firms in China, the hypotheses are tested using multilevel path analysis to account for the nesting effects.

Perceived supervisor SIB is negatively related to ACS, which in turn is related to employee CWBI and CWBO. Furthermore, employee PDO moderates the indirect effects of perceived supervisor SIB on employee CWBI and CWBO through decreased ACS. Specifically, when employee PDO is low, the indirect effects on employee CWBI and CWBO are stronger.

This is one of the first studies to investigate the influence of employee perceptions of supervisor SIB on negative employee behavior in the workplace. Furthermore, it furthers our understanding of how negative exchange can stimulate negative reciprocal behavior, which is a relatively underexplored area. Another strength of this paper is the multi-time survey design and the adoption of multilevel path analysis.

Postpandemic efforts to rebuild have steered the global economy toward a more sustainable trajectory. It is imperative to acknowledge the pressing need for further enhancements in the sustainable development of the tourism industry. This study aims to examine the influence of personal factors, including environmental concern, cultural interest, travel lifestyle and involvement, on tourist satisfaction and revisit intention, using the theory of planned behavior (TPB) as its framework.

The data was gathered through surveys conducted in three of Türkiye’s most famous slow travel destinations: Seferihisar, Gökçeada and Akyaka. The analysis was carried out using SPSS and SmartPLS software, with subsequent structural model testing.

This study presents an extended model that incorporates four individual factors, tourist satisfaction, TPB and revisit intention. All hypotheses have been rigorously tested, and the model accounts for 60.4% of the variance in revisit intention. The findings are comprehensively discussed in this article, supported by relevant theoretical frameworks.

Future research avenues could delve into the evolution of slow tourism in both developed and developing countries, assess disparities in revisit intentions between slow tourism and mass tourism destinations and investigate the prospects of sustainable tourism development in the postpandemic era.

The authors use the TPB to examine individual factors, tourist satisfaction and revisit intentions, aiming to build an extended model to gain a deeper understanding of the slow tourist decision-making process.

This paper is about equity crowdfunding syndicates as a form of entrepreneurial finance and looks specifically at the lead investors' human capital and their ability to raise funds.

The authors develop regressions on a unique hand-collected dataset of 178 lead investors taken from the US-based platform AngelList.

Results indicate that lead investors' specialized human capital has a positive effect on their syndicate fundraising performance. However, it does not find a significant effect of general human capital. It also finds that specialized human capital is mediated by the reputation of the lead investor on the platform.

This study extends human capital theory in the crowdfunding context by providing a more comprehensive portrait of human capital and in doing so, shifts the focus from an entrepreneur to an investor perspective, an approach much neglected in the crowdfunding literature.

This study advances the current knowledge on crowdfunding as it is one of the first to understand syndicate investment as an innovative and alternative platform-based financial channel. It also contributes to the current debate on the role of human capital in crowdfunding and more generally to entrepreneurial finance.

This article empirically tests the impact of risk appetite of the executive team on the re-innovation strategy after technological innovation failure using a panel regression model from the perspective of regional financial development level of enterprises.

By means of time series global principal component analysis and panel regression model method, the study validated and analyzed the impact of risk appetite of the executive team on the re-innovation strategy after enterprise technological innovation failure.

The research found that the higher the risk appetite of executive team, the more inclined the enterprise is to choose the “focusing on quantity, ignoring quality” re-innovation strategy after technological innovation failure. The better the financial development level of the region where the enterprise is located, the better it can effectively reduce the re-innovation strategy of “focusing on quantity, ignoring quality” of the enterprise due to the high risk appetite of the executive team.

The findings of this study are helpful in improving the financial development level of the region where the enterprise is located. It can help the executive team of the enterprise to more objectively choose the innovation strategy after technological innovation failure, and reduce the phenomenon that the executive team of the enterprise only pays attention to the quantity of re-innovation and underestimates the quality of re-innovation after technological innovation failure due to its high risk appetite.

Hospitality businesses have been challenged to pick fitting electronic word-of-mouth (eWOM) management strategies, yet accurate return on investment assessments and contextual contingencies interpretation essential for leveraging eWOM power are largely absent. This study aims to fill these gaps and develop a tool aiming at more holistic and accurate eWOM management assessment.

An agent-based model is developed based on eWOM-related hospitality/business theories and empirical evidence on the NetLogo 6.0.2 platform, wherein a series of simulated experiments are conducted.

Simulation patterns suggest that conformity to the majority’s choice of eWOM usage can be beneficial for consumption satisfaction, yet conformity to a group’s eWOM posting choice can compromise satisfaction. Compared to the brief reputation-boosting benefit of exaggerated advertising, honesty in advertising is preferable given its compatibility with competing eWOM distribution and long-term reputation benefits.

A preliminary tool is developed for hospitality businesses that aids the clearer interpretation of and more accurate/cost-efficient assessment of effectiveness in managing eWOM distribution. Generic directions for improved eWOM management are also provided.

A prototype model is established that surpasses existing models in its ability to capture the complexity of eWOM management and more accurately assess management effectiveness. The authors also reveal emerging novel patterns concerning the interactive dynamics of eWOM behaviors and contextual influences. The research also adds to the scarce agent-based model applications in hospitality research/practices and recommends future potential applications.

The purpose of this paper is to evaluate the co-seismic and post-seismic behaviors of an existed soil-foundation system in an actual alternately layered sand/silt ground including pore water pressure, acceleration response, and displacement et al. during and after earthquake.

The evaluation is performed by finite element method and the simulation is performed using an effective stress-based 2D/3D soil-water coupling program DBLEAVES. The calculation is carried out through static-dynamic-static three steps. The soil behavior is described by a new rotational kinematic hardening elasto-plastic cyclic mobility constitutive model, while the footing and foundation are modeled as elastic rigid elements.

The shallow (short-pile type) foundation has a better capacity of resisting ground liquefaction but large differential settlement occurred. Moreover, most part of the differential settlement occurred during earthquake motion. Attention should be paid not only to the liquefaction behavior of the ground during the earthquake motion, but also the long-term settlement after earthquake should be given serious consideration.

The co-seismic and post-seismic behavior of a complex ground which contains sand and silt layers, especially long-term settlement over a period of several weeks or even years after the earthquake, has been clarified sufficiently. In some critical condition, even if the seismic resistance is satisfied with the design code for building, detailed calculation may reveal the risk of under estimation of differential settlement that may give rise to serious problems.
