Abstract
Purpose
In many countries, innovation in building design for improving energy performance, reducing CO2 emissions and minimizing life cycle cost has received much attention for sustainable development. This paper investigates the importance of optimization tools for enhancing the design performance in the early stages of Vietnam's cooling-dominated buildings in hot and humid climates using an integrated building design approach.
Design/methodology/approach
The methodology of this study exploits the non-dominated sorting genetic algorithm (NSGA-II) optimization algorithm coupled with building simulation to research a trade-off between the optimization of investment cost and energy consumption. Our approach focuses on the whole optimization problem of thermal envelope, glazing and energy systems from preliminary design phases. The methodology is then tested for a case study of a non-residential building located in Hanoi.
Findings
The results show a considerable improvement in design performance by our method compared to current building design. The optimal solutions present the trade-off between energy consumption and capital cost in the form of a Pareto front. This helps architects, engineers and investors make important decisions in the early design stages with a large view of impacts of all factors on energy performance and cost.
Originality/value
This is one of the original research to study integrated building design applying the simulation-based genetic optimization algorithm for cooling-dominated buildings in Vietnam. The case study in this article is for a non-residential building in the north of Vietnam but the methodology can also be applied to residential buildings and other regions.

Abstract
Purpose
Vloggers (video bloggers) have emerged as a new phenomenon in social media marketing, especially in the hotel industry, where user-generated reviews can strongly influence purchase decisions. Therefore, this paper aims to build an electronic word-of-mouth (eWOM) adoption model (EAM) that incorporates source evaluation attributes (information quality, major influence and source credibility), trust in eWOM and eWOM intention (EWOMI) and booking intention and investigate the moderation of negative reviews from vloggers on relationships in the EAM.
Design/methodology/approach
This paper conducted two studies (ns1 = 446, ns2 = 374). The data were collected through an online and face-to-face survey with an experimental design. This paper conducted covariance-based structural equation model to examine main effects and applied a multiple-group analysis to test the moderating effect of vlogger reviews.
Findings
Three attributes of source evaluation are important predictors of trust in eWOM, which positively impact eWOM and booking intention. EWOMI also positively affects booking intention. Moreover, the negative review of vloggers can lower the effects of information quality on trust and of trust on EWOMI in Study 1 and on hotel booking intention in Study 2.
Originality/value
This study builds the EAM model for the hospitality context and provides novel insights into the moderating effects of vloggers’ negative reviews on the relationships in the EAM.
研究目的

Abstract
Purpose
This paper aims at identifying perceived factors and measuring opinions about the factors' impact on academic staff development (ASD) at Tay Nguyen University (TNU), Dak Lak, Vietnam.
Design/methodology/approach
The research used the exploratory factor analysis (EFA) method, the multiple regression model (ordinary least squares (OLS)) and a five-point Likert scale questionnaire. A sample of 70 managerial staff, 374 lecturers and 512 students of TNU was surveyed to obtain data.
Findings
The EFA showed that opinions concerning university autonomy (UA) and university social responsibility (USR) were positively correlated. With the above two factors united as responsible autonomy (RA), the OLS indicated perceptions that RA and internal driving factor (IF) had significant and positive impacts on the ASD, while external driving factor (EF) was found to have a perceived negative influence on ASD.
Research limitations/implications
The results indicated that there appears to be a close relationship between UA and USR, and these can be considered as a factor that has apparent impacts on the ASD of the university.
Practical implications
The degree of UA and USR of TNU should be enhanced through awareness of the university's academic staff, the application of a suitable evaluation system and the efficiency of university's regulations. In addition, efforts should be made to improve internal factors such as the dissemination of educational philosophy, the suitability of strategic plans, the development of key performance indicators KPIs and the building of organizational culture – all of which will help to heighten the university’s ASD. At the same time, TNU should endeavor to quickly transform aspects of administration and management to meet the shifting requirements of the autonomous environment and competitive features of the market economy. In particular, there is a need for the academic staff themselves to have increased capacity to adapt to these changes.
Social implications
The authors' results have a broader application to not only the case of TNU but to other situations in developing countries where universities are in transitional stages as governments assign increasing autonomy and responsibility to them.
Originality/value
This paper suggests that the academic staff of TNU should be provided with both professional autonomy and adaptive capacity to foster research and educational innovation in the market-based higher education system of Vietnam. More generally, if true, the paper suggests that an increase in the degree of UA and USR should be combined with the efforts to improve the internal environments such as disseminating educational philosophy, mission, vision and strategies and building organizational culture.

Abstract
Purpose
This study aims to develop a strategic framework for the success of coastal urban projects in Vietnam, which is one of the Asia Pacific countries significantly affected by climate change.
Design/methodology/approach
A questionnaire was used to collect data from practitioners in Vietnam. Principal component analysis (PCA) technique was used to identify critical success factors (CSFs) of coastal urban projects. A strategy map for the success of coastal urban projects was also proposed using the balanced scorecard (BSC) method.
Findings
This study identified 41 project success factors that could contribute to project success, and thence, extracted 11 CSFs for coastal urban projects using the PCA technique. In addition, 11 key performance indicators (KPIs) for coastal urban projects were listed and their linking with project success factors and CSFs was explored. Furthermore, a strategy map for the success of coastal urban projects was proposed using the BSC method. The strategy map included five perspectives: learning and growth, internal processes, social and environmental performance, financial performance, and stakeholders' satisfaction.
Originality/value
This study identified 11 CSFs for coastal urban projects and proposed a strategy map for the success of coastal urban projects.

Abstract
E‐commerce plays an important role in today’s business environment, and that role will continue to grow each year. eMarketer predicts that by “2004, world wide e‐commerce revenues are expected to total USD 2.7 trillion”. E‐commerce continues to grow in the United States. “The Census Bureau of the Department of Commerce announced today that the estimate of U.S. retail e‐commerce sales for the first quarter of 2004, not adjusted for seasonal, holiday, and trading‐day differences, was $15.5 billion, an increase of 28.1 per cent (±2.9 per cent) from the first quarter of 2003.” “According to a new study by RoperASW and AOL Time Warner, Europeans spent on average EUR430 on line between August and October 2002.” This compares with an average spend of EUR543 per head in the US over the same period.

Abstract
Purpose
This study empirically examines factors affecting the extent of balanced scorecard (BSC) adoption in Vietnamese small- and medium-sized enterprises (SMEs) such as top management involvement, an innovative culture, a product innovation strategy, organisational resources, a competitive environment and business network support. This study aims to gain an improved understanding and draw important lessons on BSC adoption for SMEs.
Design/methodology/approach
Using primary data obtained from a survey of top managers of SMEs that have experienced some forms of BSC adoption, the authors conduct their analysis using exploratory factor analysis and regression analysis methods.
Findings
The authors find that top management involvement, an innovative culture, organisational resources and business network support are essential factors impacting the extent of BSC adoption in Vietnamese SMEs. Besides confirming literature findings on these variables, the authors identify support of business networks as another important factor affecting the extent of BSC adoption, alongside location and business owners’ experience. However, the impacts of a product innovation strategy and a competitive environment are not significant.
Research limitations/implications
This study adapts scales previously designed for large enterprises in developed countries to fit into the context of Vietnamese SMEs. Future research can take advantage of this new set of scales and data to obtain further research results.
Practical implications
This study will serve as guidance for SMEs considering BSC adoption to have a clear vision of what factors are likely to affect BSC adoption, how they affect it and in what direction.
Social implications
Lessons learned can be extended not only to Vietnamese SMEs that have not yet adopted the BSC but also to firms in other countries with similar economic conditions.
Originality/value
This study is among pioneering studies on BSC in SMEs and within the context of Vietnam.

Abstract
Since the 1990s, public health agencies as well as nutrition and child health experts have recognized breastfeeding as the most appropriate infant-feeding mode for optimal health and psycho-emotional development. Consequently, breastfeeding has become a standard of good mothering, internalized by mothers, who implement a demanding self-discipline to perform breastfeeding. This dedication reflects the delegation of biopolitics to individuals in modern neoliberal societies: authoritative experts inform new parents, who then bear the responsibility of their children's health risk management. They are expected to choose appropriate practices as part of a collective strategy of risk management and anticipation of the future by changing current behaviours, aiming at the emergence of a ‘healthy body and mind’ society. Among these practices, breastfeeding holds a central place due to medical consensus about its benefits. In my ethnography of postpartum consultations by independent midwives in Switzerland, I studied the breastfeeding practices and experiences of home birth parents as part of the ‘holistic care’ provided by these midwives. Shadowing midwives during their postpartum visits between 2014 and 2017, I witnessed parents committing to the body and emotional work required to carry out their ‘breastfeeding project’, designed in continuity with their out-of-hospital birth choice. During their follow-ups, midwives engage with parents in a shared construction of meanings around breastfeeding, anchoring parenting identities in the body. I explore in this chapter the issues raised by the production of lactating maternal bodies and how women engage in body and emotional work to achieve it.

Abstract
Purpose
The purpose of this study is to contrast how the relationship between career and leadership development and workplace culture is experienced by women in two different countries and the implications this has for human resource development initiatives.
Design/methodology/approach
The study used a qualitative narrative research design to understand how the lived experiences of Australian and Vietnamese early- to mid-career female academics is engendered.
Findings
The study identified a number of key barriers and enablers that affected women’s career and leadership development. For the Australian participants, the main barrier included the competing demands of work and life and male dominated organisational cultures that discriminate against women in covert ways. The main enabler was mentoring and the building of professional networks that provided their careers with direction and support. For the Vietnamese participants, the main barriers were overt and included male-dominated organisational and societal cultures that limit their career and leadership development opportunities. The main enabler was having a sponsor or person with power in their respective organisation who would be willing to support their career advancement and gaining recognition from colleagues and peers.
Research limitations/implications
Gaining a deeper understanding of the barriers and enablers that effect women’s career and leadership development can be used to investigate how culturally appropriate developmental relationships can create ways to overcome the barriers they experience.
Originality/value
The study analysed the contrasting experiences of barriers and enablers from two cultures. The participants narrated stories that reflected on the gender politics they experienced in their career and leadership development. The narrative comparisons provide a unique lens to analyse the complex cultural experience of gender and work with potential implications for human resource development.
