A non-linear creep function embedded in an elastic visco-plastic (EVP) model can simulate the decrease of creep compression rate with time. It overcomes the limitation of a linear logarithmic creep function, by which creep continuously increases to infinite value as time approaches infinity. However, the determination of the creep model parameters is a challenging task to apply the EVP model. Therefore, this paper presents a new numerical solution to determine the EVP model parameters applying trust-region reflective least square optimisation algorithm and the finite difference scheme to simulate stress-strain behaviour of soft soil.

In this paper, the developed method is verified against the field case study of Väsby test fill. A set of EVP model parameters is obtained by applying the developed method to the available laboratory consolidation results of Väsby clay. Then, the predictions of settlement and the excess pore water pressure at different depths are compared to the available field measurement.

The analysis results show the developed method is a reliable tool to evaluate the long-term performance of soft soils under embankments.

Practicing engineers can use the proposed optimisation algorithm to increase the accuracy of the soil visco-plastic model parameters by utilising all laboratory results of several loading stages during and after the dissipation of the excess pore water pressure.

A novel numerical solution to determine the viscoplastic model parameters applying trust-region reflective least square optimisation algorithm has been developed.

This study aims to point out the importance and the relevance of sustainability issues and the need for their enhancement in the contemporary model of corporate social responsibility (CSR) as the top priority for business entities. Furthermore, it also highlights ways to enhance sustainability in the contemporary CSR model in the fast fashion industry of developing countries.

Literature review has been extensively done through available databases, including ProQuest and ScienceDirect.

This study delivers a full insight into the current state of research on the CSR model and sustainability in developing countries. The prevalent corporate environmental sustainability practices of global apparel brands are identified to propose ways to enhance sustainability in the contemporary CSR model.

The growth of fast fashion industry brings the risks of unsustainability to developing countries. Thus, it is a must for the garment and textile companies to enhance a sustainable CSR model through promoting sustainable leadership and integrating corporate culture.

To the best of author’s knowledge, this study is the first to emphasise the role of sustainable leadership in promoting a sustainable CSR model in the fast fashion industry of developing countries.

This study evaluates the important role of humane entrepreneurship (HE) on sustainable business advantage (SBA) and sustainable business performance (SBP) by exploring the mediating role of sustainable business model innovation (SBMI) under the influence of knowledge management (KM) in small and medium-sized enterprises (SMEs). Encouraging businesses to implement a combination of KM and HE facilitates the implementation of SBMI that brings value to businesses, communities and the environment in emerging economies.

This study uses an empirical quantitative research method using primary information based on data collected by questionnaires. The study sample resulted in 424 valid responses (66.77% response rate). The target audience of the study is middle and senior managers in SMEs. This study aims to perform structural modeling analysis with the maximum likelihood estimates method to examine structural relationships.

This study found a positive relationship between KM and HE to SBMI. At the same time, SBMI plays an important role for businesses to achieve SBA and SBP. Similarly, a positive relationship was also found between HE to SBA and SBP. And SBA strongly promotes SMEs to achieve SBP. In addition, the mediating role of SBMI and SBA is clarified to have a positive impact between HE–SBP and SBMI–SBP. HE plays an important role in motivating businesses to innovate sustainable business models, making it easier to gain sustainable competitive advantages, thereby bringing sustainable business results.

This research helps SMEs realize the importance of KM and HE in SBMI. At that time, SMEs take advantage of internal and external information sources and innovate their business models based on HE mechanisms. Applying HE mechanisms will allow businesses to innovate their business models by combining concerns between stakeholders and the social environment for sustainable development. Therefore, businesses will achieve their SBA toward SBP.

The present literature shows that there are few empirical studies on the mechanism mediating SBMI in the relationship between HE and SBP; and SBA in the link between SBMI and SBP. In addition, the impact of KM and HE on SBMI is also very important in the current context. The study's findings could have huge implications for entrepreneurs and senior managers in SMEs in emerging economies. Help them realize the importance of KM and HE for SBMI, thereby building strategic perspectives that help businesses achieve sustainable competitive advantages and increase SBP for businesses.

This study examines employee emotional exhaustion and turnover intention as the consequences of problematic customer behaviors and tests the role of perceived organizational justice and job satisfaction in mitigating these consequences.

A four-hypothesis model was tested using partial least squares structural equation modeling (PLS-SEM) based on a two-phase survey of 369 frontline services employees in Vietnam with a three-month time lag.

The study shows that abusive and unreasonably demanding customer behaviors have positive effects on emotional exhaustion, which, in turn, reduces job satisfaction and, subsequently, turnover intention. It also reveals that organizational justice mechanisms attenuate the positive association between emotional exhaustion and turnover intention. Job satisfaction indirectly mitigated the turnover intention of emotionally exhausted employees who had to deal with problematic customer behaviors, especially in the service sector in Vietnam, an emerging market.

Building upon the social exchange theory (SET) and the conservation of resources theory (COR), this study extended the research on organizational justice with respect to emotional exhaustion in the customer service sector that received less attention previously. Rather than merely focusing on the interpersonal factors (e.g. respect and sensitivity) as organizational support does, organizational justice encompasses employees' perception of fairness of outcome and the whole process in an organization to reach decisions.

This study aims to explore the mediating roles of self-efficacy and learning orientation in the relationship between entrepreneurship education and entrepreneurial intentions of university students in Vietnam.

The data were collected from an online survey of 1,021 university students in Vietnam. The authors conducted a hierarchical regression analysis to test the hypotheses.

The results of hierarchical regression analysis reveal that entrepreneurship education positively affects entrepreneurial intentions, and this relationship is mediated by both learning orientation and self-efficacy.

This study confirms the importance of entrepreneurship education in encouraging university students' entrepreneurial intentions.

This study offers practical implications for universities and policy makers.

This study is one of the first to empirically examine the concept of entrepreneurship education and entrepreneurial intentions in an Asia-Pacific context.

This study emphasises the significance of entrepreneurship education and its effects on university students' entrepreneurial intentions. Furthermore, the findings confirm that self-efficacy and learning orientation play an important part in explaining how entrepreneurship education relates to entrepreneurial intentions.

This study evaluates the impact of online menus and perceived convenience of online food ordering on consumer purchase intention and shows how a desire for food creates a relationship between an online menu and a customer's purchase intention. Suggestions for management are proposed to design an effective menu to improve business performance in the competitive market in Vietnam.

The paper follows a quantitative method. Quantitative research aims to analyze and critically evaluate the research question(s) to discover new factors.

Findings indicate a positive relationship between menu visual appeal (MV), menu informativeness (MI), desire for food (DF), the perceived convenience (PC) of ordering food online and intention to purchase (PI). The attractiveness of images and information is a significant factor affecting diners’ desire to eat, while the demand for food and the convenience of ordering food online are also factors affecting purchase intention.

The study confirms the importance of online menus to purchase intention. Economically, when supply and demand are reasonable, the market is stable and technology develops. In terms of social, hygiene, attractiveness and price factors, it is helpful to have an overview. Research is the premise for further studies with factors from menu to customer trust.

The study provides a solid foundation for further studies on restaurant menu elements as well as a new perspective on how restaurants improve their dishes.

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.

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.

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.

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.

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.
