Abstract
Purpose
This study aims to research the development trend, research status, research results and existing problems of the steel–concrete composite joint of railway long-span hybrid girder cable-stayed bridge.
Design/methodology/approach
Based on the investigation and analysis of the development history, structure form, structural parameters, stress characteristics, shear connector stress state, force transmission mechanism, and fatigue performance, aiming at the steel–concrete composite joint of railway long-span hybrid girder cable-stayed bridge, the development trend, research status, research results and existing problems are expounded.
Findings
The shear-compression composite joint has become the main form in practice, featuring shortened length and simplified structure. The length of composite joints between 1.5 and 3.0 m has no significant effect on the stress and force transmission laws of the main girder. The reasonable thickness of the bearing plate is 40–70 mm. The calculation theory and simplified calculation formula of the overall bearing capacity, the nonuniformity and distribution laws of the shear connector, the force transferring ratio of steel and concrete components, the fatigue failure mechanism and structural parameters effects are the focus of the research study.
Originality/value
This study puts forward some suggestions and prospects for the structural design and theoretical research of the steel–concrete composite joint of railway long-span hybrid girder cable-stayed bridge.

Abstract
Purpose
This study aims to explore the relationship between risk governance characteristics (chief risk officer [CRO], chief financial officer [CFO] and senior directors [SENIOR]) and regulatory adjustments (RAs) in Organization for Economic Cooperation and Development public commercial banks.
Design/methodology/approach
Using principal component analysis (PCA) and regression models, the research analyzes a representative data set of these banks.
Findings
A significant negative correlation between risk governance characteristics and RAs is found. Sensitivity analysis on the regulatory Tier 1 capital ratio and the total capital ratio indicates mixed outcomes, suggesting a complex relationship that warrants further exploration.
Research limitations/implications
The study’s limited sample size calls for further research to confirm findings and explore risk governance’s impact on banks’ capital structures.
Practical implications
Enhanced risk governance could reduce RAs, influencing banking policy.
Social implications
The study advocates for improved banking regulatory practices, potentially increasing sector stability and public trust.
Originality/value
This study contributes to understanding risk governance’s role in regulatory compliance, offering insights for policymaking in banking.

Abstract
Purpose
Although both institutional export assistance and entrepreneurial orientation (EO) contribute separately and positively to export performance, the interplay between them has received little attention. This study examines the role of international EO in deriving performance benefits from governmental and nongovernmental export assistance.
Design/methodology/approach
In this longitudinal study, two surveys were administered at two different times: In 2011, 705 Bangladeshi apparel exporters were surveyed, and in 2019, a subsequent survey of 198 firms in multiple industries was conducted. The aim of the surveys was to assess the relationships between governmental and nongovernmental assistance, EO and export performance.
Findings
The results of the first survey show that, while nongovernmental assistance influences performance directly and via EO, governmental assistance has only direct effects. Furthermore, the negative influence of government assistance on EO reduces the total effects and renders them nonsignificant. The results of the second survey demonstrate that government EPPs have both direct and indirect positive and significant effects on market performance, indicating a partial mediation, whereas quasi-governmental assistance has positive and significant direct effects as well as negative but nonsignificant indirect effects. Nongovernmental EPPs have both direct and indirect significant effects on international performance, indicating a partial mediation.
Research limitations/implications
The study has important implications for researchers studying export assistance and its impact on firm performance. Instead of adopting a parochial view of government assistance, this study categorizes such assistance into three types – government, quasi-government and nongovernment. Furthermore, this study bridges the export assistance and international entrepreneurship literature by including EO.
Practical implications
Entrepreneurs must emphasize the use of government assistance in order to enhance export performance. However, to promote both entrepreneurship and performance, they must emphasize nongovernment assistance. Exporters should also capitalize on the assistance extended by various quasi-governmental agencies to bolster export performance.
Originality/value
Given the performance advantage of export assistance, this study highlights the contribution of the private sector in promoting export entrepreneurship while shedding light on the pernicious role of (quasi-)governmental assistance in export entrepreneurship.

Abstract
Purpose
Damage functions constitute an essential part of the modelling of critical infrastructure (CI) performance under the influence of climate events. This paper aims to compile and discuss publications comprising damage functions for transport assets.
Design/methodology/approach
The research included the collection of contemplable literature and the subsequent screening for damage functions and information on them. In conclusion, the derived damage curves and formulae were transferred to a unified design.
Findings
Damage functions for the transport sector are scarce in the literature. Although specific damage functions for particular transport assets exist, they mainly consider infrastructure or transport in general. Occasionally, damage curves for the same asset in different publications vary. Major research gaps persist in wildfire damage estimation.
Research limitations/implications
The study scope was restricted to the hazards of fluvial floods and wildfires. Despite all efforts, this study did not cover all existing literature on the topic.
Originality/value
This publication summarises the state of the art of research concerning transport asset damage functions, and hence contributes to the facilitation of prospective research on CI performance, resilience and vulnerability modelling.

Abstract
Purpose
This article analyzes the concepts of experience economy and promotion of authenticity at The Venetian Hotel and Casino in Las Vegas by exploring the resort's tangible and intangible heritage use in design and marketing strategies.
Design/methodology/approach
This qualitative study conducts a content analysis of marketing material, historical documents, and site observations.
Findings
Visitors' active involvement, combined with The Venetian's use of tangible and intangible heritage, is used in creating an authentic themed experience. In addition, our study suggests that authenticity constitutes a key concept for today's hospitality industry.
Research limitations/implications
This study centers on a single case study, and requires adjustments in order to be replicated. However, The Venetian represents one of the most prominent models followed by the hospitality industry worldwide.
Practical implications
This analysis provides a baseline for comparison among resorts that have theming but do not integrate it in the same way, or in general, to other professionals and academics considering themed experiences.
Social implications
The manuscript centers on several aspects that are being debated in numerous fields, from business to sociology, such as customers' desire for authentic experiences through the creation of themed attractions.
Originality/value
This research fills a gap in hospitality marketing research into authenticity and themed experience by investigating how The Venetian Hotel and Casino uses the heritage of another, tourism-focused city (Venice) to promote itself. The investigation uncovers how themed attractions in hospitality create an experience-based involvement that centers on the authenticity of the theme (in our case cultural heritage) they replicate.

Abstract
As the wave of liberalization and deregulation have accelerated to relieve rigid controls over airline routes, capacity, and fare setting regimes, Low Cost Carriers (LCCs) have emerged especially in local aviation markets since the 1970s.
This paper has studied the effects of LCC's entry into the domestic aviation market which was pre-occupied by two major carriers, Korean Air (KAL) and Asiana Airlines. Through a simple model describing two situations, prior and post to LCC's entry, we analyzed changes and trends of each airline's output and profit based on the Cournot and two-stage Stackelberg game equilibrium.
In summary, our conclusion consists of five points: (1) Even though JIN Air's entry reduced KAL's respective output and profit, the more JIN Air produces, the higher the joint-profit of KAL and JIN Air is, (2) From the joint-profit aspect, increasing KAL's output to a level than JIN Air's is more profitable on the Gimpo-Jeju route, on the other hand, increasing JIN Air's output higher than KAL's is more profitable on the Jeju-Busan route, (3) Even though JIN Air's entry increase Asiana Airline's output, the more JIN Air produces, the less Asiana Airlines's profit is, (4) Total output in markets as well as total profits of firms will increase under certain conditions, (5) KAL and JIN Air tend to get caught in an unresolved conflict on level of LCC cost.

Abstract
Purpose
This study aims to examine the impact of habitual Facebook use (HFU) on life satisfaction and psychological well-being. In addition, the study examined the impact of life satisfaction on psychological well-being. Moreover, the study investigates the impact of social safeness in moderating the relationship between HFU and life satisfaction.
Design/methodology/approach
The study employed a quantitative survey design, using a sample of 261 Generation Y students based in Mthatha, in the Eastern Cape Province of South Africa. Scales for data collection were operationalized from prior studies. The collected data were analyzed using structural equation modeling.
Findings
The study’s results disclosed that HFU positively and significantly impacts life satisfaction and psychological well-being. In addition, life satisfaction positively and significantly impacted psychological well-being. Moreover, the results showed that social safeness had a positive and significant moderating effect on the nexus between HFU and life satisfaction.
Originality/value
This study contributes to understanding HFU as a precursor to life satisfaction and psychological well-being among Generation Y students. Also, evaluating the moderating effect of social safeness contributes to a more thorough understanding of the link between HFU and life satisfaction. Furthermore, this research aims to add to the body of knowledge in Africa’s communication psychology and social media literature, a field that has received little academic attention in developing countries.

Abstract
Purpose
This study provides an analysis of professional development school (PDS) dissertation research that focuses on learning in PDSs. These 103 dissertations written between 1990 and 2020 address an aspect of learning in PDS work, including inquiry as a pedagogical learning tool, student learning PK-12, intern/teacher candidate learning, university teacher educator learning, and inservice teacher learning. From the current exploration of PDS dissertations, most especially from the comparison studies, the authors have learned that there is still no clear path to presenting PDS as having a positive impact when compared with non-PDS experiences..
Design/methodology/approach
Within each of these categories, the authors examine the dissertations by methodology and explore common themes among dissertation findings. As the PDS movement enters its third decade of inquiry and builds its efficacy on models of learning, the findings provide insight into the degree to which PDS scholars are building on the past to determine future PDS research agendas around learning.
Findings
The authors examine the dissertations by methodology and explore common themes among dissertation findings. The themes included: intern learning does happen in PDS sites; PDSs provide structures for intern learning; teacher educators can learn from their PDS work; dissertations in the area of student learning overwhelmingly had inconclusive findings, except for research that focused on targeted interventions, which demonstrated student gains.
Research limitations/implications
With fewer PDS-focused dissertations being written in more recent years, the authors wonder if the complexity of PDS may be a deterrent to the growth and sustainability of this model?
Practical implications
From the current exploration of PDS dissertations, most especially from the comparison studies, the authors have learned that the authors still do not have a clear path to presenting PDS as having a positive impact when compared with non-PDS experiences. However, the authors are beginning to understand the types of studies that are needed to move this agenda forward and hope the work will help inform the PDS community of some.
Originality/value
This is the first known study of PDS dissertations across time.
