Abstract
Purpose
Risks are considered a significant obstacle to Green Building (GB) development and have recently received significant attention from both construction practitioners and academics. This study aimed to identify critical GB risks and explore the relationship between participants' characteristics and risk assessment.
Design/methodology/approach
Firstly, a list of GB risks was developed based on a comprehensive literature review and interviewing GB experts. After that, a survey of 207 construction professionals was then conducted to validate these GB risk factors. Finally, this research adopted the ANOVA test and hierarchical regression analysis to examine the relationship between participants' characteristics and risk assessment.
Findings
The results provided a list of GB risks classified and evaluated according to the GB project life cycle and, thus, may serve as a helpful reference for GB practitioners. Notably, the ANOVA analysis revealed that risk assessment negatively correlates with participants' GB experience, while their industry experience does not affect risk assessment. Furthermore, the hierarchical regression analysis proved that participant roles do not moderate the association between risk assessment and GB experience.
Originality/value
This study contributed to GB literature by implementing empirical research on GB risks in a developing country. The results implied the essential role of professionals with rich GB experience in risk management in GB projects. Furthermore, this research could help construction practitioners understand GB risks adequately and thereby have better risk-management strategies for future GB projects.

Abstract
Purpose
This paper aims to look into the role of transformational leadership and transactional leadership as predictors of employee creativity and organisational innovation. Employee creativity is examined as a potential mediator in the leadership styles–organisational innovation relationships.
Design/methodology/approach
A cross-sectional, quantitative design was adopted and structural equation modelling (SEM) techniques were used to analyse data collected from 369 employees working in 39 public coffee enterprises in Vietnam.
Findings
Transformational leadership and transactional leadership were significant predictors of employee creativity and organisational innovation. Specifically, transformational leadership was instrumental to employee creativity and organisational innovation while transactional leadership was detrimental to these two variables. Additionally, employee creativity partially mediated the relationships between the two leadership styles and organisational innovation.
Practical implications
Results of this study benefit the management of organisations and policy makers by providing an insight of which leadership style will effectively suit public enterprises to promote employee creativity and foster organisational innovation.
Originality/value
While there is a lack of studies investigating organisational innovation in organisational methods and that the interrelationships between leadership styles, employee creativity and organisational innovation are not fully understood, this study pioneers in examining relationships between leadership styles and organisational innovation that is being mediated by employee creativity. Figuring out that organisational innovation is more likely to be fostered by the positive influence of leadership behaviours and the improvement of employee creativity, in particular, the significant role of employee creativity represents important contributions of the current study.

Abstract
Purpose
Determining alarm levels of river floods is considered an effective non-structural measure to prevent and mitigate the damages of flood and inundation. This study aims to propose a holistic approach, a comprehensive review of the factors affecting flooding and flood risk, based on which the water level (WL) is proposed for the flood alarm levels. The corresponding proposed WL to the necessary flood alarm levels is based on observed data, as well as simulated data from statistical methods and hydrological and hydraulic models.
Design/methodology/approach
In this paper, the proposed criteria to delineate WLs corresponding to flood alarm levels include flood magnitude; flood derivation and flood duration; flood risks and damage; correlation with neighboring stations; flood characteristics and local characteristics; and other criteria (flood prevention strategy and flood experience).
Findings
The paper proposed a synthesis approach to determine flood warning levels in Vietnam. The retrieved levels are the basics to revise the Decision 632/2010 of the Vietnam Government on determining water alarm levels for flood prevention. The study proposes a new flood alarm system including revised flood levels at 115 existing stations and new flood levels at 30 additional stations. The proposed flood warning level can help manage the flooding problem in major river systems that supports flood protection and prevention services in Vietnam.
Originality/value
The paper proposed a novel synthesis approach to flood prevention in Vietnam.

Abstract
Purpose
This study aims to examine the impact of managerial use of motivating language on employee absenteeism, turnover intention, job satisfaction and job performance for employees from three nations: India, the USA and Vietnam.
Design/methodology/approach
Data is collected from 614 employees working in India, the USA and Vietnam. A variance-based partial least squares structural equation modeling technique is used to test the hypotheses. In addition, a statistical test is used to examine the statistical differences in the results across the three nations.
Findings
The findings are consistent with the motivating language theory, in that managerial use of motivating language can be an effective strategy in motivating employees. Specifically, motivating language is found to significantly decrease employee absenteeism and turnover intention, as well as significantly increase job satisfaction and performance across the three nations. The effect sizes indicate that, across all samples, motivating language has a medium effect for all employee outcomes, except absenteeism, which is shown to have a small effect size. Moreover, the results indicate that employees in different cultures perceive and interpret the leader’s use of motivating language in different ways. Whereas motivating language may receive greater success in promoting workers’ job performance in eastern cultures, it is also more effective in retaining employees in western cultures.
Originality/value
The study adds to the literature in three major ways. First, it provides evidence for two understudied relationships: motivating language and absenteeism and motivating language and turnover intention. Second, it assesses the generalizability of the motivating language theory by investigating data from India, the USA and Vietnam. Finally, this paper offers a statistical comparison of the three samples to analyze how the relationship between motivating language and worker outcomes differ among the three samples.
