Abstract
Purpose
Recognition that not every climate adaptation policy is a good one has shifted attention to new tools and methods to measure the adequacy and effectiveness of adaptation policies. This study aims to propose and apply and applies an innovative adaptation policy assessment framework to identify the extent to which climate adaptation policies in Vietnam exhibit conditions that are likely to ensure a sufficient, credible and effective adaptation.
Design/methodology/approach
In total, 21 conditions, categorized under five normative principles and covering critical issue areas in adaptation domain, form the climate adaptation policy assessment framework. The principles were double-checked and tested in case studies through observations and analyses of policy documents to ensure that each condition should be distinct and not overlapping across principles. To see if the principles and attendant conditions were able to capture all relevant aspects of adaptation, the authors used structured expert judgment. In total, 39 policy documents pertaining to climate change adaptation were selected for qualitative document analysis. In-depth interviews with local officials and experts were conducted to address data gaps.
Findings
The study reveals major weaknesses constituting a reasonably worrisome picture of the adaptation policies in Vietnam since several critical conditions were underrepresented. These results shed new light on why some adaptation policies falter or are posing adverse impacts. The findings suggest that a sound policy assessment framework can provide evidence on what effective adaptation policy looks like and how it can be enabled. The framework for climate adaptation policy assessment in this study can be easily adjusted and used for different socio-environmental contexts in which new conditions for policy assessment might emerge.
Social implications
The findings show underlying weaknesses constituting a reasonably worrisome picture of the adaptation regime in Vietnam. In the absence of mechanisms and measures for accountability and transparency in policy processes, adaptation in Vietnam appears more likely to be prone to maladaptation and corruption. While solving these problems will not be easy for Vietnam, the government needs to evaluate whether the short-term gains in sustaining the existing adaptation policies really make progress and serve its long-term climate-adaptive development goals.
Originality/value
Although interpretations of adaptation effectiveness may be very divergent in different normative views on adaptation outcomes, the authors argue that a common, agreed-upon effectiveness can be reached if it is clearly defined and measurable in adaptation policies. Thus, the climate adaptation policy assessment framework proposed in this study is critical for policymakers, practitioners, donors and stakeholders dealing with adaptation to better understand the weaknesses in policymaking processes, pinpoint priority areas of action and timely prevent or prepare for possible adverse impacts of policies.

Abstract
Purpose
The strength and stiffness of steel deteriorate rapidly at elevated temperatures. Thus, the characteristics of steel structures exposed to fire have been concerned in recent years. Most studies on the fire response of steel structures were conducted at uniformly distributed temperatures. This study aims to evaluate the buckling capacity of steel H-beams subjected to different loading conditions under non-uniform heating.
Design/methodology/approach
A numerical investigation was conducted employing finite element analysis software, ABAQUS. A comparison between the numerical analysis results and the experimental data from previous studies was conducted to verify the beam model. Simply supported beams were loaded with several loading conditions including one end moment, end equal moments, uniformly distributed load and concentrated load at midspan. The effects of initial imperfections were considered. The buckling capacities of steel beams under fire using the existing fire design code and the previous study were also generated and compared.
Findings
The results showed that the length-to-height ratio and loading conditions have a great effect on the buckling resistance of steel beams under fire. The capacity of steel beams under non-uniform temperature distribution using the existing fire design code and the previous study can give unconservative values or too conservative values depending on loading conditions. The maximum differences of unconservative and conservative values are −44.5 and 129.2% for beams subjected to end equal moments and one end moment, respectively.
Originality/value
This study provides the buckling characteristics of steel beams under non-uniform temperature considering the influences of initial imperfections, length-to-height ratios, and loading conditions. This study will be beneficial for structural engineers in properly evaluating structures under non-uniform heating conditions.

Abstract
Purpose
This study aims to investigate the effect of the presence of women in top executive positions on financial reporting quality (FRQ) and the role of external audit in enhancing the role of women in top executive positions.
Design/methodology/approach
This study uses a sample of 644 Vietnamese-listed firms from 2010 to 2020 and applies fixed-effect and dynamic system generalized method of moments techniques for empirical models to test the related hypotheses.
Findings
First, this study found a U-shaped relationship between women on the board and FRQ as well as women on the audit committee and FRQ. Second, female CEOs are positively associated with FRQ in small firms but there is no evidence of this in large firms. Third, a female chief accountant can enhance FRQ. Finally, external audit quality can reduce the negative effect of women on the board and the audit committee on FRQ and increase the positive impact of female chief accountants on FRQ.
Practical implications
The results support all risk-averse, ethical sensitivity and glass ceiling hypotheses in different contexts. This study provides important implications for firms to enhance FRQ by nominating women in a majority of top executive positions and simultaneously using high-quality external audit services.
Originality/value
The impact of women in top executive positions on controlling FRQ in different contexts is an original contribution to gender in management literature.

Abstract
Purpose
This article aims to draw a conceptual model that integrates the view from the entrepreneurial event model with entrepreneurial education and prior self-employment experience. The model tests the role of entrepreneurial education on the formation of intentions to become an entrepreneur and examines whether prior self-employed experiences moderate the route from entrepreneurial education, entrepreneurial perceived feasibility (PF) and perceived desirability (PD) into the entrepreneurial intention (EI).
Design/methodology/approach
The authors operated on a sample of 389 master's students by applying Cronbach's alpha, exploratory factor analysis, confirmatory factor analysis and structural equation modelling to illustrate the links between constructs.
Findings
The study found that entrepreneurial education is positively correlated with PF, PD, and intention to enter entrepreneurial activities. PD is determined as a partial mediator in the entrepreneurial education–intention link and full mediator in PF and EI. Moreover, the study revealed that prior self-employed experiences serve as a positive moderator in the path from entrepreneurial education and PD to EI.
Practical implications
The study offers several recommendations based on research findings so as to nurture and promote entrepreneurial activities among master's students.
Originality/value
The current research provides novel insights about the relationship between entrepreneurial education and intentions to become an entrepreneur over and about the central antecedents in the entrepreneurial event model and moderation effects of prior self-employed experiences.

This study aims to examine the relationship between bank capital and bank risk during COVID-19.
Abstract
Purpose
This study aims to examine the relationship between bank capital and bank risk during COVID-19.
Design/methodology/approach
The study covers 20 countries during the period from Q4:2018 to Q4:2020, using different measurements of risk with consideration for the interrelationship between bank risk and bank capital and the impact of COVID-19.
Findings
The findings show that higher bank capital mitigates bank market risk and default risk; banks incur higher market risk during the COVID-19 period, and these risks are greater if banks have higher capital levels; and low-capitalized banks reduce risks more than well-capitalized banks, and moderately low-capitalized banks behave the most prudentially. These results are robust to different capital measures and model settings.
Practical implications
The research results are important in proving the motivation and practicality of capital regulation as well as the impact of COVID-19 as an exogenous shock to the bank’s operations.
Originality/value
To the best of the authors’ knowledge, this is the first study to investigate the influence of the COVID-19 pandemic on the relationship between bank capital and bank risk. In addition, while most of the studies on this nexus are based on the US data and the conclusions are inclusive; our results provide empirical cross-country evidences on the relationship between bank capital and bank risk.

This study aims to investigate the effect of digitalization on bank profitability among Vietnamese banks.
Abstract
Purpose
This study aims to investigate the effect of digitalization on bank profitability among Vietnamese banks.
Design/methodology/approach
The research employs fixed-effects regression on a panel data of 32 banks in Vietnam during the period 2010–2021.
Findings
The study reveals a positive impact of digitalization on bank profitability. The result is robust to different measures and empirical settings. Not surprisingly, small banks and banks with high percentage of state ownership experience lower profitability than their peers. However, digitalization helps improve the profitability of these banks. This study explains the effect by showing that digitalization significantly reduces bank cost in terms of cost to income ratio and increases bank non-interest income through diversification into non-traditional products and services. In addition, the current stage of bank digitalization in Vietnam does not reduce banks’ employment costs since it requires staffs to support and operate the new system.
Practical implications
The research findings are motivations for bankers and policy-makers in designing appropriate strategies toward digitalization. Investors can also consider highly digitalized banks as valuable investment.
Originality/value
This research extends the current literature on the relationship between digitalization and bank profitability, with a focus on commercial banks in Vietnam. Given the high involvement of the government and the dominance of several large banks in the banking system, the study also explores whether the effect of digitalization on bank profitability varies with the bank’s size and state ownership. Last but not least, the channels in which digitalization affects bank profitability are also examined.

Abstract
Purpose
This study examines the impact of economic policy uncertainty (EPU) on investment decision-making of start-up firms in Japan. While existing literature suggests firms generally retrench investment under EPU, the authors argue that start-ups’ investment behaviours are likely different given the fact that start-ups always have to compete for survival.
Design/methodology/approach
The authors investigate the impact of general economic policy and policy-specific uncertainty, including monetary policy, fiscal policy, trade policy and exchange rate policy uncertainty, on corporate investment of start-up firms using multiple fixed-effect regression. A wide range of robustness and endogeneity tests are conducted to ensure the validity and soundness of the empirical findings.
Findings
The authors document a positive effect of EPU on start-up investment, to suggesting that the investment behaviour of start-ups is backed by venture capital distinct from that of mature firms. The results show that start-ups are more vulnerable during the changes in trade and exchange rate policies; uncertainties in monetary and fiscal policies do not restrain firms' investment. However, the effect varies in the cross-sections. Financial constraints have a moderating effect on the relation-ship between EPU on start-up investment. Institutional investors have an incremental effect on the positive relationship between EPU and start-up investment by encouraging risky investments.
Originality/value
This is the first study to investigate how start-up investment is influenced by EPU, thus providing a new understanding of the investment behaviour of start-up firms during uncertainty. Further investigation sheds light on the roles of institutional and managerial ownership in this newfound relationship.

Abstract
Purpose
This paper presents the outcomes of the international project “Protecting Landscape Heritage: a requalification project as an instrument for the re-birth of Quang Tri Old Citadel in Vietnam”, achieved with scientific cooperation between the Università Politecnica delle Marche (Italy) and Hue University of Sciences (Vietnam) funded by the Italian Ministry of Foreign Affairs and International Cooperation and Ministry of Science and Technology of Vietnam. The research focuses on the Quang Tri Citadel, founded in 1809 and now in an advanced state of degradation.
Design/methodology/approach
For the purpose of rehabilitation, the wide multidisciplinary project first examined the historical context of the military model, the architectural aspects of the structure, the characterization of the existing materials, the degradation levels of different parts, and, finally, a proposal of the suggested interventions.
Findings
The original structure and geometry were extrapolated and studied. Building materials were produced with nearby raw materials. Firing temperatures of bricks ranged from 800 to 1,000 °C, hydraulic lime was supposed the binder of the mortar with a calcination temperature lower than 1,000 °C. Damage assessment was provided and after these analyses a requalification project was proposed so the cultural heritage can play a role for the future in the dialog between different cultures.
Originality/value
The requalification project achieved by an integrated analytical approach defines aspects in relation to the restoration of the structures, enabling compliance with the geometry, techniques, building materials used in the original construction and allowing its guardianship and management to align with the historical context of the architectural heritage.
