Abstract
Purpose
Consistent with an “absolute bonding hypothesis,” the benefits of listing on US exchanges experienced by cross-listed firms are accompanied by an increased risk of experiencing a spillover effect due to negative news within their industry. The purpose of this study is to test this form of the bonding hypothesis by analyzing the spillover effect to cross-listed firms when class action lawsuits are filed against their industry peers.
Design/methodology/approach
The bonding hypothesis is tested by analyzing the spillover effect to non-sued cross-listed firms of class action lawsuits brought against US domestic firms in the same industry. The spillover effect is identified using cumulative abnormal returns around lawsuit filing dates from 1996 to 2020. A sample of matched non-sued cross-listed and domestic peer firms is evaluated in a cross-sectional analysis to identify country and firm-level characteristics that mitigate the negative spillover effect to cross-listed firms.
Findings
While US firms realize significantly negative abnormal returns when class action suits are filed against their industry peers, the impact to cross-listed peers is statistically insignificant. In multivariate analyses, we show that the ability of cross-listed firms to avoid this negative spillover effect is stronger for firms with greater profitability that are headquartered in countries with better shareholder protections and governance characteristics.
Originality/value
Results suggest that cross-listed firms may have a level of immunization from the negative industry spillover effect of class action lawsuits and, thus, exhibit only “partial bonding” to the US market.

Abstract
Purpose
The purpose of this paper is to propose an optimal energy management (OEM) method using intelligent optimization techniques applied to implement an optimally hybrid heat and power isolated microgrid. The microgrid investigated combines renewable and conventional power generation.
Design/methodology/approach
Five bio-inspired optimization methods include an advanced proposed multi-objective particle swarm optimization (MOPSO) approach which is comparatively applied for OEM of the implemented microgrid with other bio-inspired optimization approaches via their comparative simulation results.
Findings
Optimal multi-objective solutions through Pareto front demonstrate that the advanced proposed MOPSO method performs quite better in comparison with other meta-heuristic optimization methods. Moreover, the proposed MOPSO is successfully applied to perform 24-h OEM microgrid. The simulation results also display the merits of the real time optimization along with the arbitrary of users’ selection as to satisfy their power requirement.
Originality/value
This paper focuses on the OEM of a designed microgrid using a newly proposed modified MOPSO algorithm. Optimal multi-objective solutions through Pareto front demonstrate that the advanced proposed MOPSO method performs quite better in comparison with other meta-heuristic optimization approaches.

Abstract
Purpose
This paper aims to propose an advanced tracking control of the uncertain nonlinear dynamic system using a novel hybrid fuzzy linear quadratic regulator (LQR)-proportional-integral-derivative (PID) sliding mode control (SMC) optimized by differential evolution (DE) algorithm.
Design/methodology/approach
First, a swing-up and balancing control is presented for an experimental uncertain nonlinear Pendubot system perturbed with friction. The DE-based optimal SMC scheme is used to optimally swing up the Pendubot system to the top equilibrium position. Then the novel hybrid fuzzy-based on LQR fusion function and PID controller optimized by DE algorithm is innovatively applied for balancing and control the position of the first link of the Pendubot in the down-right position with tracking sinusoidal signal reference.
Findings
Experimental results demonstrate the robustness and effectiveness of the proposed approach in balancing control for an uncertain nonlinear Pendubot system perturbed with internal friction.
Originality/value
This manuscript is an original research paper and has never been submitted to any other journal.

This paper aims to analyze the effects of organizational factors on electronic customer relationship management (e-CRM) successful implementation.
Abstract
Purpose
This paper aims to analyze the effects of organizational factors on electronic customer relationship management (e-CRM) successful implementation.
Design/methodology/approach
Data were collected through a structured questionnaire survey conducted in Vietnam. The dataset consists of 241 valid responses by individuals working at Vietnamese airlines. Correlation analysis and structural equation modeling were used to examine the causal relationships among organizational factors, customer orientation, knowledge management, data quality and CRM strategy.
Findings
The result shows that organizational factors have influence on e-CRM success. However, there are other factors needed to be more considered that are customer orientation having the most influence, following by knowledge management and technology. Still other factors have indirect effect on e-CRM success such as data quality and CRM strategy.
Originality/value
This study is among the first to examine an integrated model depicting the direct and indirect effects of organization factors on e-CRM success. From this perspective, this paper provides an improved understanding of how customer orientation and organizational factors, technology and knowledge management influences airlines applying e-CRM. This study also provides several implications for practice. The paper suggests airline providers and marketing managers, especially those in Vietnam, focus more on customer orientation activities. The paper also recommends that airlines should pay attention to its organizational structure in line with its customer-orientation strategy.

Abstract
Purpose
The purpose of this paper is to characterize the optimal ordering and allocation policy for a store replenishment decision in the context of an omnichannel retailer in a franchise network. The authors further show that a myopic policy is optimal, which circumvents the curse of dimensionality for the multi-period inventory model and help store managers optimize their decisions about the amount of inventory to stock for both online and offline demands and the percentage of inventory to reserve for online orders.
Design/methodology/approach
This research is trigged by several managerial studies which suggest reserving a certain percentage of the in-store inventory for online orders as a good store inventory allocation practice for omnichannel retailers in a franchise network. The authors used an analytical model to develop this practice by clarifying how store managers can decide on the amount of inventory to replenish and the percentage to reserve for online orders.
Findings
This study develops a finite horizon, periodic review inventory model to identify an optimal and dynamic replenishment and allocation policy. The analysis uncovers the system’s fundamental structural property concavity. The research shows that, due to this property, the optimal replenishment policy is a base-stock policy. The latter is due to the base stock level being independent of the initial inventory at hand, and the optimal allocation level being non-decreasing on the base-stock level.
Research limitations/implications
This study contributes to the literature on store inventory management for omnichannel retailers in a franchise network by investigating their optimal store inventory ordering and allocation policy. Nevertheless, the zero-lead time and zero-setup cost assumptions limit the findings.
Practical implications
Insights into an optimal store inventory policy may guide franchisee store managers to decide on the amount of inventory to replenish and the percentage to reserve for online orders.
Originality/value
The originality of this paper lies in its focus on in-store inventory management for omnichannel retailers in a franchise network. The findings are helpful for franchisor retailers to implement the omnichannel strategy at the level of in-store inventory management. Beyond using incentive systems, the franchisor should leverage legitimate powers by mentioning a relevant measure in their contracts with their franchisee to minimize their channel conflicts and ensure their customers have seamless shopping experiences.

Abstract
This chapter provides information on the development of Vietnamese education under the influence of global forces based on the analysis of relevant education research and policies using Wolhuter’s frameworks. In the process of coming up with ways to develop education in the face of different influences of globalization, besides having reactions with patterns commonly found in countries around the world, Vietnam also has responses that reflect its own political, sociocultural and economic characteristics. The state still plays a controlling role in education at all levels and many culture-related features that have existed throughout the country’s history have hardly changed, namely aspects related to teachers, learners and teaching and learning methods. To sustain its education in the globalized era, Vietnam must make more efforts in various aspects such as the link between education and employment, the logic of education objectives, the feasibility and appropriateness of curricula, quality of education, especially of higher education and equality in education for underprivileged groups.

Abstract
The community college model is evolving in the Socialist Republic of Viet Nam. During June 2009, 11 of the 12 existing higher education institutions with “community college” in their official name were examined utilizing a qualitative multiple-case study approach. Data were collected in the field from June 1 to 23, 2009, while making visits to each of the 11 colleges, the Ministry of Education and Training (MOET), and the Vietnam Association of Community Colleges (VACC). Five data collection techniques were utilized to examine the bounded system: (a) semi-structured interviews, (b) survey of the college rectors, VACC informant and MOET informant, (c) participant observation with field notes, (d) document review, and (e) photographs taken during each site visit. After the field study stage, e-mail communication with the study informants between August 2009 and March 2010 clarified questions and developed a deeper level of understanding of the Vietnamese community college model. Results of the study (Epperson, 2010) indicate that although legislation does not exist to permanently establish the higher education institutions named community colleges, a community college model does exist and is in a state of evolution. The model can be defined by a set of core characteristics which emerged from the data. Five themes were particularly prominent: (a) public higher education institutions with community ownership at the provincial or city level, in conjunction with MOET oversight for academic matters; (b) multidisciplinary programs designed to meet the unique needs of the community; (c) multi-level certificates and diplomas conferred up through the college level (three year) of higher education and articulation agreements with universities enable students to earn a university bachelor's degree; (d) domestic and international partnerships are actively sought to develop social capital; (e) scientific and technological research based on community needs as required in the 2005 Education Law.

Abstract
Purpose
This study aims to dispense a concrete and coherent picture on the role of digitalization of accounting information (DOAI) among the small and medium-sized enterprises (SMEs) through a statistically reliable and parsimonious paradigm for procuring the impact of DOAI on sustainable innovation ecosystem (SIE) and public value (PV) generation. With this cue, the geographical scope of this tentative manuscript was framed in SMEs of developing countries.
Design/methodology/approach
A three-pronged methodology was disposed in this research, namely, literature review, expert interviews and self-administered survey. Qualitative data was procured from a series of semi-structured in-depth interviews. The quantitative data was drawn on a self-administered survey in which the closed-ended questionnaires were conveniently circulated to a cross-sectional sample of 583 respondents. The data captured from quantitative approach was processed and analyzed via covariance-based structural equation modeling with AMOS 26.0.
Findings
The outcomes analysis highlighted that there were significant positive associations between the hypothesized constructs regarding significance and effect size. These interlinks were also partially mediated through the mediation of quality of information on financial reports and SIE.
Research limitations/implications
This research was bounded by geographical provenance emphasis on one country and relative smallness of the data set procured through anonymous survey-based approach drawn from a convenient sample of digitally savvy respondents working in one sub-sector resulted in the reduction in the robustness and generalizability of the observations. Nevertheless, these above-mentioned limitations could thus offer the starting points for novel avenues creation for the future research.
Practical implications
The practitioners would definitely have valuable benefits from in-depth insights on the obtained findings. Concretely, as lifting the degree of understandings on the magnitude of long-term cooperation and superior coordination within the SIE would enable practitioners to enlarge their business viewpoints to better cope with the challenges of complicated business settings, facilitating them to co-create PV for all their key stakeholders through giving priority to implementing DOAI.
Social implications
Society could benefit from this study if policymakers and the influencers of government focus on innovative features and assure the possible environment for innovation deployment through embarking on introducing policies that would facilitate the digitalization as well as stimulate and incentivize establishing the SIE for PV generation. It would be good for both the SMEs and society when SMEs could thrive in community settings as well as this togetherness.
Originality/value
Unpacking the potential of DOAI has been considered as the promising research avenues that are outlined not only to redress the shortfall in the research stream in relation to the digitalization among SMEs but also provide the right directions for sustainable development among SMEs.

Abstract
Purpose
The purpose of this paper is to trace the way in which a popular ritual became one of Vietnam’s most important festivals, elevated as a celebration of national heroism and charts its gradual transformation in modern society.
Design/methodology/approach
This research focuses on the combination of a fertility rite and narratives of St Gióng based on nationalism or heroism created a special festival reflecting many traditional cultural characteristics of Vietnam and the Việt people and the transformation of St Gióng from a mythological to a national symbol of heroism in anti-invader history was recorded in texts.
Findings
The paper casts light on the mythologization and historicization of St Gióng in Vietnam’s particular historical context by decoding the Gióng symbol as a core element of the folktales and myths about St Gióng to understand the formation and development of St Gióng in the cultural history of Vietnam.
Research limitations/implications
The paper is not exploring the Gióng symbol within a larger cultural context of nationalism and ethnosymbolic approach in a comparison of national symbolism and heroism.
Practical implications
The paper includes implications for advised scholars to conduct further exploration of the symbol and myth of not only St Gióng in Vietnam but also Kubera in India and Vaisravana in China to connect Kubera, Vaisravana and St Gióng under the connection of literal myth and heroic symbol.
Social implications
The paper shows how processes of historicizing myth and mythologizing history are important features of Vietnamese socio-historical research.
Originality/value
The paper shows how a fertility rite became a historical festival and the figure of St Gióng became a symbol of patriotic heroism.

Abstract
Purpose
Building on my earlier work (Dang, 2007, 2008), this chapter provides an updated review of the private tutoring phenomenon in Vietnam including the reasons, scale, intensity, form, cost, and legality of these classes. In particular, this chapter offers a comparative analysis of the trends in private tutoring between 1998 and 2006 using all available data.
Design/methodology/approach
This chapter analyzes data from different sources, including (i) the 2006 Vietnam Household Living Standards Measurement Survey (VHLSS), (ii) the 1997–1998 Vietnam Living Standards Measurement Survey (VLSS), (iii) the 2008 Vietnam Household Testing Survey (VHTS), and (iv) local press in Vietnam. Quantitative methods are used.
Findings
Several (micro-)correlates are examined that are found to be strongly correlated with student attendance at tutoring, including household income, household heads’ education and residence areas, student current grade level, ethnicity, and household sizes. In particular, I focus on the last three variables that received little attention in the previous literature on the determinants of tutoring.
Originality/value
This chapter provides an updated and systematic review of the private tutoring phenomenon in Vietnam. Findings are highly relevant to the ongoing debates on private tutoring among all stakeholders in Vietnam, as well as policymakers/researchers in other countries. Suggestions are proposed on current gaps in the literature for future research.
